Description

  The present invention relates to an adhesive tape attaching apparatus for attaching an adhesive tape to an object to be attached.

  In the manufacturing process of a flat panel display such as a liquid crystal display and an organic EL display, it is necessary to mount an electronic component on a substrate which is an object to be adhered. This mounting is performed, for example, by temporarily pressing an electronic component to a terminal portion provided on the peripheral upper surface of the substrate via a pressure-sensitive adhesive tape, followed by heat-pressure bonding.

  The attached electronic component is, for example, a TCP (Tape Carrier Package). TCP is a package in which a chip such as an IC is mounted on a thin film. The adhesive tape is, for example, a tape made of ACF (Anisotropic Conductive Film), having a width of several millimeters and a thickness of several tens of microns. ACF is a resin-made anisotropic conductive film containing metal particles.

  Thus, the thin adhesive tape is comprised as a tape-shaped member affixed on the release tape. The tape-shaped member is fed out from the reel, and after the adhesive tape is pressure-bonded to the substrate, only the release tape is peeled off and discharged. As a guide member for guiding the movement of such a tape-like member, a reel-like member having a side wall with an interval equivalent to the width of the tape-like member is known.

Japanese Patent Laid-Open No. 7-270742

  In general, a substrate to which an adhesive tape is attached is a substrate in which a pair of glass plates are attached. And the electrode formation part which is a crimping | compression-bonding location of the adhesive tape in the peripheral part of a board | substrate is a part which fractured | ruptured the edge part of one glass plate and exposed the other glass plate. In such an electrode forming portion, the width of the press-bonded portion of the tape at the peripheral edge of the substrate is narrower because of the demand for a larger display screen and a smaller outer dimension.

  On the other hand, the guide member that guides the movement of the tape-like member is a reel-like member, and in order to ensure smooth movement of the tape-like member, the groove width of the reel-like member is slightly larger than the width of the tape-like member. Forming. Therefore, when the tension applied to the tape-shaped member fluctuates in the cycle of supplying the tape-shaped member, press-bonding to the substrate, and peeling the release tape, the position of the tape-shaped member is wide. Fluctuate in direction. As a result, the position of the pressure-sensitive adhesive tape with respect to the crimped portion becomes unstable.

  As described above, when the position of the tape-shaped member in the width direction becomes unstable even though the width of the crimped portion tends to be narrow, the tape-shaped member is likely to be misaligned with respect to the crimped portion. It becomes difficult to wear.

  The present invention has been proposed in order to solve the above-mentioned problems of the prior art, and its purpose is to prevent the positional deviation of the tape-shaped member in the width direction and to enable accurate sticking. The object is to provide a tape sticking device.

  An example of an embodiment of the present invention (hereinafter referred to as an embodiment) will be specifically described with reference to the drawings. As shown in FIG. 1, the tape-like member 2 used in the present embodiment is, for example, one in which an ACF adhesive tape 21 is attached to a release tape 22. The release tape 22 is a tape that can be peeled off from the adhesive tape 21 and is formed of, for example, a resin film such as polyimide. The width of the tape-like member 2 that is generally used is about 0.5 to 3.5 mm.

  Moreover, the sticking target object of the tape-shaped member 2 is the board | substrate 3 which comprises a flat panel display, for example. As shown in FIGS. 1 and 2, the substrate 3 is formed by bonding a pair of flat plates, and the edge of the other flat plate is exposed from the edge of the one flat plate. In the electrode portion formed in the exposed portion, a sticking location 3a indicated by a two-dot chain line in FIG. 2, which is a region to which the adhesive tape 21 cut to a predetermined length is attached, is set.

[Constitution]
The sticking apparatus 1 of this embodiment has the sticking part 11, the cutting part 12, the supply part 13, the discharge | emission part 14, guide part 15A, 15B, and the peeling part 16, as shown in FIG. The sticking part 11, the cutting part 12, the supply part 13, the discharge part 14, the guide parts 15A and 15B, and the peeling part 16 are each attached to a support body such as a frame or a plate (not shown) that constitutes the main body of the sticking apparatus 1. ing. Hereinafter, the structure of each part of the sticking apparatus 1 is demonstrated.

[Attaching part]
The sticking part 11 is a structural part for sticking the adhesive tape 21 in the tape-like member 2 to the substrate 3 as the sticking object. The sticking unit 11 includes a pressure head 110 and a backup member 111.

  The pressure head 110 heats and presses the tape-like member 2 against the substrate 3 by moving up and down by a lifting device (not shown). Therefore, the pressure head 110 is provided with a heater (not shown), and the contact surface with the tape-like member 2 is heated to a predetermined temperature. Further, a buffer member 110 a is provided on the contact surface of the pressure head 110 with the tape-like member 2. The buffer member 110 a is, for example, a sheet formed of an elastic body, and prevents the adhesive tape 21 softened by heating from adhering to the pressure head 110.

  The backup member 111 is a rectangular parallelepiped block that supports a portion of the substrate 3 that is pressed by the pressure head 110 from below when the tape-shaped member 2 is heated and pressed by the pressure head 110. The backup member 111 has a support surface 111 a that is a flat surface that supports the substrate 3 on the upper surface thereof.

[Cut part]
The cutting part 12 is a structural part that cuts only the adhesive tape 21 in the tape-like member 2. The cutting of only the adhesive tape 21 in this way is hereinafter referred to as a half cut. The cutting unit 12 includes a cutter 120 and a backup member 121. The cutter 120 is a member that contacts and cuts the adhesive tape 21. The cutter 120 comes into contact with and separates from the adhesive tape 21 by a lifting mechanism (not shown). The backup member 121 is a rectangular parallelepiped block. This backup member 121 has a flat surface 121a that sandwiches the tape-like member 2 with the cutter 120 and contacts the release tape 22 in the horizontal direction on the lower surface of the block.

[Supply section]
The supply unit 13 is a component that supplies the tape-like member 2 to the sticking unit 11. The supply unit 13 includes a supply reel 130, a tension mechanism 131, and a path roller 132. The supply reel 130 is a reel that winds the tape-shaped member 2 and feeds the tape-shaped member 2 by rotation.

  The tension mechanism 131 is a component that applies tension to the tape-like member 2. The tension mechanism 131 is a pair of rollers arranged at a distance from each other in the vertical direction so as to guide the movement of the tape-like member 2 pulled out from the supply reel 130. One roller is a fixed roller 131a that does not move up and down, and the other roller is a movable roller 131b that can move up and down. The movable roller 131b moves up and down by a lifting mechanism (not shown). That is, it moves in the direction of the black arrow in the figure.

  The load applied to the tape-like member 2 by such a tension mechanism 131 is adjusted to be, for example, about 3 g to 100 g. The optimum tension of the tape-like member 2 varies depending on the width of the tape-like member 2, but if it is a general tape-like member 2, the tape-like member 2 can be transported without problems if the load is adjusted within the above range. This has been confirmed by the applicant's experiment. However, when it is expected that the effect on the adhesive tape 21 is reduced, about 20 to 50 g is preferable. Here, when a tension greater than 100 g is applied to the general tape-shaped member 2, the tape-shaped member 2 wound around the supply reel 130 is tightened, and the adhesive component contained in the adhesive tape 21 flows out. There is a risk that a problem may occur in which the tape-like member 2 wound around is stuck. Therefore, it is not preferable to apply a tension larger than 100 g.

  The path roller 132 is a roller that changes the moving direction of the tape-like member 2 from the tension mechanism 131 and feeds it toward the cutting unit 12.

[Discharge part]
The discharge unit 14 is a component that discharges the release tape 22 peeled from the adhesive tape 21 attached to the substrate 3 in the attachment unit 11. The discharge unit 14 includes a collection reel 140, a feed roller 141, and a path roller 142.

  The collection reel 140 is a reel that winds and collects the release tape 22. The feed roller 141 is a processing unit that sandwiches the release tape 22 with a pair of rollers and moves the tape-shaped member 2 from the supply reel 130 side to the collection reel 140 side by rotation of the rollers.

  The path roller 142 is a roller that changes the moving direction of the release tape 22 from the sticking unit 11 side and feeds it toward the collection reel 140.

[Guide section]
The guide portions 15A and 15B are components that are arranged on the supply portion 13 side and the discharge portion 14 side with the sticking portion 11 in between, and guide the movement of the tape-like member 2 from the supply portion 13 toward the discharge portion 14. .

  As shown in FIGS. 2 and 3, the guide portions 15 </ b> A and 15 </ b> B have pin shapes each having a body portion 150, an inclined portion 151, and a restriction portion 152. The trunk portion 150 is a cylindrical portion whose axis extends in the horizontal direction. The inclined portion 151 is a component having an inclined surface 151a that is in contact with the surface of the moving release tape 22 and is inclined with respect to the horizontal direction. The restricting portion 152 is provided at the end of the inclined portion 151 and is in contact with one side edge of the tape-like member 2 (the release tape 22 in the guide portion 15B on the downstream side in the conveying direction) that moves along the inclined surface 151a. By this, it is a structure part which controls the position of the width direction of the tape-shaped member 2 (release tape 22). A surface with which the side edge of the release tape 22 in the restricting portion 152 contacts is referred to as a reference surface 152a.

  The inclined portion 151 of the present embodiment has a truncated cone shape with a diameter reduced toward the restricting portion 152, the large diameter portion side is formed to have the same diameter as the trunk portion 150 and is connected to the trunk portion 150, and the small diameter portion side is formed. A regulating portion 152 is provided at the end. The guide portions 15A and 15B do not rotate. As shown in FIG. 3, the inclined surface 151 a of the inclined portion 151 is a surface on which the surface of the moving release tape 22 (the surface opposite to the surface to which the adhesive tape 21 is attached) is in sliding contact. In other words, the tapered surface which is the outer peripheral surface of the truncated cone functions as the inclined surface 151a on which the release tape 22 slides. The inclined surfaces 151a of the inclined portions 151 in the pair of guide portions 15A and 15B are inclined in the same direction and have the same inclination angle.

  The restricting portion 152 of the present embodiment is a disc-shaped flange, and is provided concentrically with the truncated cone-shaped inclined portion 151. The restricting portion 152 is formed so that the radius is larger than the radius of the small diameter portion of the inclined portion 151, and the difference in radius is larger than the thickness of the tape-like member 2. Further, as shown in FIG. 2, the restriction portions 152 in the pair of guide portions 15A and 15B are arranged so that the respective reference planes 152a coincide with the virtual straight line Y, in other words, on a straight line. ing. Here, the board | substrate 3 will be positioned with respect to the sticking part 11 so that the edge part of the center side of the board | substrate 3 in the sticking location 3a may correspond with this virtual straight line Y. FIG. In addition, the board | substrate 3 does not necessarily have to position the said edge part of the sticking location 3a in alignment with the virtual straight line Y, and is offset by a predetermined amount in the direction orthogonal to the edge of the sticking location 3a. You may make it do. In this embodiment, the imaginary straight line Y is one of the contact surfaces of the pressure head 110 with the tape-like member 2 that is long in the transport direction of the tape-like member 2 in plan view. More specifically, the long side is a straight line located at the same position in the vertical direction as the long side on the near side in FIG.

  As shown in FIG. 4, the inclination angle α of the inclined surface 151a of the inclined portion 151 is about 1 ° to 30 ° with respect to the horizontal direction. For example, when the inclination angle α is large, a slight curve (bow-like deformation) may occur in the tape-like member 2 between the guide portion 15A and the guide portion 15B. The curvature tends to occur more easily as the width of the tape-like member 2 is larger. As a result of an experiment conducted by the inventors to examine the relationship between the width dimension of the tape-like member 2 and the inclination angle α, the inclination angle α exceeds 10 ° when the width of the tape-like member 2 is 2.5 mm or more and 3.5 mm or less. A curve with an unacceptable size, that is, a curve with a size that prevents the adhesive tape 21 from being attached to the application location 3a. Further, when the width of the tape-like member 2 was 1.5 mm or more and less than 2.5 mm, an unacceptable curve occurred when the inclination angle α exceeded 20 °. When the width of the tape-like member 2 was less than 1.5 mm, an unacceptable curve occurred when the inclination angle α exceeded 30 °. In any condition, the tension applied to the tape-like member 2 was set in the range of 20 g to 50 g. From this result, the inclination angle α may be set in the range of 1 ° to 30 ° according to the width of the tape-like member 2 to be used. However, if the inclination angle α is set to 1 ° to 10 °, it is more preferable because almost no bending occurs in any of the width types of 0.5 to 3.5 mm which are general tape-like members 2. . Further, the width β of the inclined surface 151a of the inclined portion 151 is the same as or larger than the width of the tape-like member 2, and specifically, it may be about 0.5 mm to 3.5 mm. . This corresponds to the width type of the general tape-like member 2. In addition, if the width β of the inclined surface 151a is set to 3.5 mm or more, it is possible to cope with the tape-like member 2 of any width without exchanging the guide portions 15A and 15B. Moreover, when the inclination angle α of the inclined surface 151a is small, the force for urging the tape-shaped member 2 toward the regulating portion 152 is weakened. This urging force does not cause a problem if the inclination angle α is 1 ° or more.

[Peeling part]
The peeling part 16 is a structure part which peels the release tape 22 from the adhesive tape 21 stuck to the board | substrate 3, as shown in FIG. The peeling portion 16 includes the guide portion 15B on the discharge portion 14 side and a peeling rod 160. The guide portion 15B moves in the horizontal direction. Further, the peeling bar 160 is a member that moves together with the guide portion 15B and contacts the surface of the release tape 22. The guide part 15B and the peeling bar 160 are attached to the adhesive tape 21 that is pressure-bonded to the substrate 3 by moving to the sticking part 11 side (in the direction of the dotted arrow in the figure) while the release tape 22 is in contact. The released release tape 22 can be peeled off.

[Action]
[Overall behavior]
The operation of the present embodiment as described above is as follows. First, as shown in FIG. 1, the substrate 3 is supplied to the support surface 111 a of the backup member 111 by a not-shown transport device or the like, and the sticking location 3 a on the substrate 3 is placed. On the other hand, the tape-like member 2 is unwound from the supply reel 130 and is wound around the collection reel 140 via the tension mechanism 131, the path roller 132, the guide portions 15A and 15B, and the path roller 142. Then, the tape-like member 2 is conveyed by driving the feed roller 141. Such movement of the tape-like member 2 by the feed roller 141 is set to be intermittent so as to stop at the timing of pressure bonding to the substrate 3 and half cut.

  The tape-shaped member 2 is half-cut by the cutter 120 at the timing when the planned cutting position is stopped at the cutting position by the cutter 120 by the conveyance by the feed roller 141. That is, only the adhesive tape 21 of the tape-like member 2 is sequentially cut so that the length in the longitudinal direction is the same as the length of the sticking portion 3 a of the substrate 3. At the time of this half cut, the tape-like member 2 slightly inclined by the inclined portion 151 is urged by the cutter 120 and pressed against the flat surface 121a of the backup member 121, so that the tape-like member 2 becomes horizontal. Each cut adhesive tape 21 passes between the pressure head 110 and the backup member 111, and as shown in FIG.1 and FIG.2, above the sticking location 3a of the board | substrate 3 supported by the support surface 111a. Sequentially face each other.

  In this way, the adhesive tape 21 cut to a predetermined length and positioned on the substrate 3 is heated and pressurized and adhered to the substrate 3 when the pressure head 110 is lowered. Thereafter, the pressure head 110 is raised to release the tape-like member 2 and the peeling portion 16 is moved, whereby the release tape 22 is peeled from the adhesive tape 21 that is pressure-bonded to the substrate 3. The peeled release tape 22 is wound around the collection reel 140 and discharged. The electronic component is mounted on the substrate 3 to which the adhesive tape 21 has been attached by temporarily bonding the electronic component to the adhesive tape 21 in the subsequent process and then applying the heat and pressure to the main pressure bonding.

[Operation of guide section]
In the process of transporting the tape-shaped member 2 by the feed roller 141 as described above, the movement of the tape-shaped member 2 is guided as follows by the guide portions 15A and 15B.

  First, as shown in FIG. 3, the tape-shaped member 2 is moved in contact with the inclined surface 151 a of the inclined portion 151, so that the tape-shaped member 2 is inclined with respect to the horizontal direction. . Since the inclined surface 151a of the inclined portion 151 in the pair of guide portions 15A and 15B has the same direction and the same inclination angle, the tape-like member 2 between the guide portions 15A and 15B is inclined in the same direction without being twisted. Move with.

  When such an inclination exists, the tape-like member 2 is always urged toward the side having the smaller diameter in the inclined portion 151, that is, the regulating portion 152 side (the direction of the white arrow in FIGS. 2 and 3), and the tape The side edge of the shaped member 2 is in contact with the reference surface 152 a of the restricting portion 152. As shown in FIG. 2, the reference surface 152a of the pair of guide portions 15A and 15B coincides with the virtual straight line Y, and the edge of the tape-like member 2 on the regulation portion 152 side coincides with the virtual straight line Y. Thus, the positional variation in the width direction is prevented. Moreover, since the board | substrate 3 is positioned so that one edge of the sticking location 3a may correspond to this virtual straight line Y, the position shift from the sticking location 3a of the tape-shaped member 2 is prevented.

  That is, even when the tension applied to the tape-like member 2 by the tension mechanism 131 fluctuates when the tape-like member 2 is stopped and moved by the feed roller 141, the inclined surface 151a of the inclined portion 151 is slid, Always contacts the reference surface 152a of the restricting portion 152, so that the position of the tape-shaped member 2 in the width direction is stabilized. Further, the inclination of the tape-like member 2 due to the inclined surface 151 a is corrected in the horizontal direction along the substrate 3 when the cutter 120 presses the tape-like member 2 against the flat surface 121 a of the backup member 121.

[effect]
(1) In the present embodiment as described above, the adhesive tape of the tape-like member 2 is supplied to the supply unit 13 that supplies the tape-like member 2 having the adhesive tape 21 attached to the release tape 22 and the substrate 3. Positioning of the supply part 13 across the sticking part 11 and the discharge part 14 which discharges | releases the release tape 22 peeled from the adhesive tape 21 stuck to the board | substrate 3, the sticking part 11 which sticks 21 And guide portions 15A and 15B for guiding the movement of the tape-like member 2 from the supply portion 13 toward the discharge portion 14, respectively.

  And guide part 15A, 15B is provided in the edge part of the inclined part 151 which has the inclined surface 151a which the surface of the moving mold release tape 22 touches, and inclined with respect to the horizontal direction, and the inclined part 151a, and is inclined surface 151a. And a regulating portion 152 that regulates the position in the width direction of the release tape 22 by contacting one side edge of the release tape 22 that moves along the side.

  In the guide portions 15A and 15B having such a configuration, the tape-like member 2 is urged toward the side where the diameter of the inclined portion 151 is smaller along the inclined surface 151a of the inclined portion 151 during conveyance. Therefore, the edge in the width direction is always in contact with the restricting portion 152. For this reason, since the side edge of the tape-shaped member 2 always moves in contact with the restricting portion 152, the position of the tape-shaped member 2 in the width direction is stabilized, and accurate attachment to the substrate 3 can be performed. Further, since one side edge of the tape-like member 2 is not restricted, the tape-like member 2 can always be positioned with reference to the other side edge even if the width of the tape-like member 2 to be used is different. For this reason, for example, when the movement of the tape-like member 2 is guided by a reel-like member having a side wall with an interval corresponding to the width of the tape-like member 2, the tape-like member 2 having a different width is used. Every time you do it, you don't have to change the members or adjust the width of the side wall.

(2) The restricting portion 152 is a disc-shaped flange portion, and the inclined portion 151 has a truncated cone shape whose diameter is reduced toward the flange portion. Therefore, for example, by fixing the guide portions 15A and 15B so that the shaft stands upright from the support surface of the support for fixing the guide portions 15A and 15B, the angles of the inclined portion 151 and the regulating portion 152 are taken into consideration. Without having to do both.

(3) The inclined surface 151a is a surface with which the surface of the moving release tape 22 comes into sliding contact. For this reason, the movement of the tape-like member 2 can be stably guided and the structure can be simplified as compared with the case where the inclined portion 151 rotates or the like.

(4) It has the peeling part 16 which peels the release tape 22 from the adhesive tape 21 affixed on the board | substrate 3, and the peeling part 16 and the guide part 15B by the side in which the discharge | emission part 14 which moves to a horizontal direction is located And a peeling bar 160 that moves together with the guide portion 15B and contacts the surface of the release tape 22. Thus, since one guide part 15B is comprised as the peeling part 16, a structure can be simplified.

(5) It has the cutting part 12 which cut | disconnects only the adhesive tape 21 in the tape-shaped member 2, and the cutting part 12 is a tape between the cutter 120 which contacts the adhesive tape 21, and cut | disconnects the adhesive tape 21, and the cutter 120. And a backup member 121 having a flat surface 121a in contact with the release tape 22 in the horizontal direction. For this reason, since the inclination of the tape-like member 2 is corrected in the horizontal direction when half-cutting is performed by the cutter 120, more accurate crimping is possible.

(6) The inclination angle of the inclined surface 151a is 1 ° to 30 °. For this reason, curving of the tape-like member 2 is suppressed and accurate sticking becomes possible.

(7) The length corresponding to the width of the tape-like member 2 on the inclined surface 151a is 0.5 to 3.5 mm. For this reason, the general tape-like member 2 can be used without requiring replacement or adjustment of the member.

(8) It has a tension mechanism 131 for applying a tension of 20 to 50 g to the tape-like member 2. For this reason, an appropriate tension is applied to the tape-like member 2 to prevent a large slack, and the positioning toward the regulating portion 152 can be maintained.

(9) When the width of the tape-shaped member 2 is in the range of 0.5 mm to 3.5 mm and the tension applied to the tape-shaped member 2 is set in the range of 20 g to 50 g, the inclination angle of the inclined surface 151 a is 1 °. It set to the range of -10 degrees. For this reason, if it is a general tape-shaped member 2, the adhesive tape 21 stuck on the sticking location 3a is correctly with respect to the sticking location 3a, without replacement | exchange and adjustment of guide part 15A, 15B. It can position, and the adhesive tape 21 can be correctly affixed on the adhesion location 3a.

[Other Embodiments]
The present invention is not limited to the above embodiment. For example, the inclined portion 151 in the guide portions 15 </ b> A and 15 </ b> B only needs to be able to apply a force in a direction in which the tape-like member 2 is moved to the regulating portion 152 side by the tension applied to the tape-like member 2. For this reason, as shown in FIG. 5, the inclined part 151 can also be made into the member which inclined the rod-shaped or plate-shaped member with respect to the horizontal direction. In such a case, the cross section of the inclined portion 151 may be circular as shown in FIG. 6 (A) or polygonal as shown in FIGS. 6 (B) and 6 (C). Further, as shown in FIG. 6D, the tape-like member 2 is slid in contact with each other by forming rounded corners or curving the plate-like member as shown in FIG. 6E. It may be formed so that the tape-like member 2 moves smoothly. That is, when the movement path lengths of the edge portion located on the restriction portion 152 side and the other edge portion in the width direction of the tape-like member 2 are compared, the movement route length of the edge portion located on the restriction portion 152 side is more It suffices if the inclined portion 151 is configured so as to be shorter.

  In addition, as shown in FIG. 7A, a part from the support ends of the guide portions 15A and 15B to the restriction portion 152 may be an inclined portion 151, or as shown in FIG. May be the inclined portion 151. Furthermore, since the regulation part 152 should just be able to regulate the position of a side edge of the tape-shaped member 2, the angle is not limited to perpendicular | vertical. For example, as shown in FIG. 7C, the direction may be orthogonal to the inclined surface 151a of the inclined portion 151.

  Moreover, as shown in FIG. 8, the cross section of the tape-shaped member 2 in the width direction of the inclined surface 151a of the inclined portion 151 shown in each of the above embodiments may be a curve. Thereby, since the direction of the tape-like member 2 approximates the horizontal direction in the vicinity of the restricting portion 152, the tape-like member 2 between the guide portions 15A and 15B can be more reliably prevented from bending.

  In the above embodiment, the guide portions 15A and 15B do not rotate and the tape-like member 2 slides. However, the guide portions 15A and 15B may be configured by rollers that rotate. The material of the guide portions 15A and 15B may be any material that allows the tape-like member 2 to slide smoothly, such as metal or resin. Moreover, you may make it perform the process which can make the tape-shaped member 2 slide smoothly on the inclined surface 151a of guide part 15A, 15B, for example, a fluorine coating process, and a plating process.

  Furthermore, the structure of the sticking part 11, the supply part 13, the discharge part 14, etc. is not limited to the above embodiment, All the well-known techniques are applicable. The tension mechanism 131 does not need to be a part of the supply unit 13 and may be disposed in any one of the paths of the tape-like member 2. The feed roller 141 does not need to be a part of the discharge unit 14 and may be disposed in any one of the paths of the tape-like member 2. As the discharge unit 14, there may be a component that discharges the release tape 22 peeled from the adhesive tape 21. For this reason, the structure which winds around the collection | recovery reel 140 is not necessarily required. For example, an area for vacuuming and discharging the release tape 22 by a suction device using reduced pressure may be provided. Further, a container or a compartment in which the release tape 22 is temporarily accommodated can also be regarded as the discharge unit 14. Furthermore, the opening through which the release tape 22 is discharged can also be regarded as the discharge portion 14.

  Moreover, this invention can be comprised as a sticking apparatus of the adhesive tape as a part of component mounting apparatus which mounts an electronic component. Furthermore, the sticking object is not limited to the above-described substrate. For example, it may be an electronic component that attaches a tape-shaped member before being mounted on a substrate, such as TCP.

  Further, the backup member 121 of the cutting part 12 may be arranged so that the flat surface (supporting surface) in contact with the release tape 22 is always in contact with the release tape 22 as well as when the adhesive tape 21 is cut. . By doing so, the tape-like member 2 supported between the guide portions 15A and 15B in an inclined state by the inclined surfaces 151a of the guide portions 15A and 15B is in contact with the flat support surface of the backup member 121 so that it is horizontal. It is possible to always keep the tape-shaped member 2 that is supported between the guide portions 15 </ b> A and 15 </ b> B in a horizontal state, not only when the adhesive tape 21 is cut.

  Moreover, although it demonstrated as what inclines the inclined surface 151a of guide part 15A, 15B with respect to a horizontal direction, in this application, the direction parallel to the surface of the board | substrate 3 supplied to the sticking part 11 is made into a horizontal direction. . Therefore, in the case of the sticking apparatus 1 supplied to the sticking unit 11 in a state in which the substrate 3 is inclined with respect to the horizontal direction, for example, orthogonally, in the present application, the vertical direction is regarded as the horizontal direction. To do.
