Detailed ways

Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

The automatic film tearing device 100 and the automatic film tearing system according to the embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 5 .

As shown in FIG. 1 , the automatic film tearing device 100 according to the embodiment of the first aspect of the present invention includes: a glue feeding unit 10 , a mucous membrane unit 20 and a cutting unit 30 .

The glue feeding unit 10 is used for containing the adhesive tape 200 for tearing film and controlling the supply of the adhesive tape 200 . That is to say, the adhesive tape 200 is set in the gluing unit 10 and driven by the gluing unit 10 so that the adhesive tape 200 can be delivered, making preparations for the realization of the following adhesive tape 200 being uncovered and the film 500 being torn off. Besides, the gluing unit 10 is configured to be movable so as to drive the adhesive tape 200 to tear off the film 500 . In other words, the glue feeding unit 10 is not only used to supply and give out the adhesive tape 200 , but also can drive the adhesive tape 200 to move together so that the adhesive tape 200 moves together with the film 500 , so that the film 500 is torn off.

The adhesive film unit 20 is slidably connected to the glue feeding unit 10 to be suitable for driving the adhesive tape 200 to stick on the covering film 500 . It can be understood that the main function of the adhesive film unit 20 is to provide a compressive force for sticking the adhesive tape 200 on the covering film 500 so as to make the bonding between the two more tightly. Among them, the "slidable" in "the mucous membrane unit 20 is slidably connected to the glue feeding unit 10" is not limited to sliding along a straight line, but can also slide along a curve or slide along a certain spatial preset track, as long as it can play a role. The movement modes of the action of attaching the adhesive tape 200 to the cover film 500 all fall within the above-mentioned "slidable" range.

The cutting unit 30, the gluing unit 10, and the mucous membrane unit 20 are fixedly connected. That is to say, each of the above three units is fixedly connected to at least one of the other two units.

The cutting unit 30 is suitable for cutting the adhesive tape 200 pasted on the cover film 500 . Specifically, the cutting unit 30 cuts off the adhesive tape 200 pasted on the covering film 500, so that the used adhesive tape 200 and the covering film 500 can be separated from the unused adhesive tape 200 as a whole, so as to realize detachment. The continuous use of 200 can also enhance the continuity of the film. The previously used adhesive tape 200 includes at least the portion of the adhesive tape 200 that is attached to the cover film 500 .

The applicant has found through research that manual tearing of the film is not only inefficient, especially for softer and thinner peelable adhesive films, it is more likely to cause the adhesive film to adhere to the adhesive tape 200 during the tearing process, resulting in the need for manual tearing. The problem of frequent replacement of the adhesive tape 200 occurs. For this reason, the embodiment of the present invention designs the above-mentioned automatic film tearing device 100, which can realize automatic tearing off. Of course, the automatic film tearing device 100 is not limited to the tearing off of the peelable adhesive film, and is applicable to the tearing off of the film 500 attached to a certain part or component.

In summary, according to the automatic film tearing device 100 of the embodiment of the present invention, by using the glue feeding unit 10, the mucous membrane unit 20 and the cutting unit 30 to complete a series of operations such as automatic glue feeding, automatic mucous membrane, and automatic demoulding, it can quickly and Automatically complete the action of replacing the tape 200 and tearing off the film layer. There is no need to replace the tape 200, just cut off the few tapes 200 pasted on the film 500, and realize the integration of film tearing, especially for medium and large sizes. (such as products above 7 inches), it reduces the static electricity, dust, dirt, damage and other defects caused by manual tearing of the film, and improves the product quality and tearing efficiency in the process of tearing the film, which has good feasibility.

To facilitate film tearing, the gluing unit 10 is configured to be movable or rotatable. That is to say, the gluing unit 10 can drive the adhesive tape 200 and the film 500 to move as a whole to tear the film, or the gluing unit 10 can rotate the adhesive tape 200 and the film 500 to tear the film as a whole. Of course, the present invention is not limited thereto. The gluing unit 10 can also tear the film by moving and rotating at the same time, or the gluing unit 10 can be torn by moving first and then rotating, or by rotating first and then moving. membrane.

In addition, the above-mentioned moving manner is not limited to a single moving direction, and may also move in two different directions successively to realize the tearing off of the covering film 500 .

In the specific embodiment shown in Figure 2, the glue feeding unit 10 includes a glue feeding mechanism 11, the glue feeding mechanism 11 includes a pressing wheel 111 and a driving wheel 112, the driving wheel 112 is configured to be driven to rotate, and the driving wheel 112 A first channel through which the adhesive tape 200 passes is defined between the side wall and the side wall of the pressing wheel 111 .

Thus, when driving the driving wheel 112 to rotate, the rotating driving wheel 112 drives the adhesive tape 200 to move together, and the pressing wheel 111 can better support the adhesive tape 200, so that the adhesive tape 200 can move outward smoothly through the first channel And be sent out, the above-mentioned glue feeding mechanism 11 is not only simple in mechanism, but also has high driving efficiency.

Specifically, as shown in FIG. 2 , the glue feeding mechanism 11 also includes a housing 13, the adhesive tape 200 is installed in or on the housing 13, and the driving wheel 112 of the glue feeding mechanism 11 is pivotally connected to the The casing 13, the pressing wheel 111 can be fixedly connected to the casing 13, and can also be pivotally connected to the casing 13. The central axes of the pressing wheel 111 and the driving wheel 112 can be parallel to each other, so that the side walls of the two are limited. A gap for the adhesive tape 200 to pass through, that is, the first channel.

The adhesive tape 200 can be wound in rolls, and the winding center of the adhesive tape 200 is parallel to the central axis of the driving wheel 112 , so that the force exerted by the driving wheel 112 on the adhesive tape 200 can be maximized.

The glue feeding mechanism 11 can also include a power source for driving the driving wheel 112, such as a drive cylinder, a drive motor, a drive motor and a transmission mechanism. The power sources included in each unit can be independent or can be Different outputs of a power source.

As shown in FIG. 2 , the side wall of the driving wheel 112 may be provided with a plurality of protruding teeth 112 a, and the plurality of protruding teeth 112 a are evenly distributed along the circumference of the driving wheel 112 . In this way, when the drive wheel 112 drives the tape 200 to move, the protruding teeth 112a can provide greater friction to ensure that the tape 200 is pulled out continuously and stably, and avoid slipping between the drive wheel 112 and the tape 200 .

Optionally, all of the driving wheel 112 or the protruding teeth 112a of the driving wheel 112 are elastic members. Therefore, the sidewall surface of the driving wheel 112 is elastic, and can generate a certain elastic deformation to elastically squeeze the tape 200 , thereby preventing the tape 200 from retracting when the tape 200 is cut.

Specifically, the drive wheel 112 as a whole may be an elastic wheel with elasticity, such as a silicone wheel, a plastic wheel, and the like. Of course, the driving wheel 112 can include a wheel body and an annular sleeve body, and the protruding teeth 112a can be integrated on the annular sleeve, and the annular sleeve is sheathed on the wheel body of the driving wheel 112 (similar to the combination mode of a tire and a hub), at this time , the annular sleeve body can be directly set as an elastic member, so that the annular sleeve can be directly replaced when the protruding teeth 112a are worn out by friction, which saves the cost.

In addition, as shown in FIG. 1 and FIG. 3 , the glue feeding mechanism 11 of the glue feeding unit 10 has a first passage extending in the vertical direction for the adhesive tape 200 to pass through. The mucous membrane unit 20 is arranged below the glue feeding mechanism 11. 20 is configured to drive the free end 201 of the adhesive tape 200 out of the glue feeding unit 10 in the horizontal direction.

In this way, the direction in which the adhesive tape 200 initially protrudes is the vertical direction, which makes reasonable use of the space and makes the arrangement of the film tearing device more compact and reasonable. The adhesive tape 200 is attached on the covering film 500, and the final extension direction of the adhesive tape 200 can be changed so that the free end 201 of the adhesive tape 200 extends substantially horizontally, so that the adhesive tape 200 can be directly attached to the covering film 500, improving The tightness and stability of the fit are ensured.

The specific structure of the mucous membrane unit 20 and the trajectory of the mucous membrane wheel 22 can be designed according to the initial position of the adhesive tape 200 , the position of the glue feeding mechanism 11 , and the final extension position and direction of the adhesive tape 200 . For example, as shown in FIG. 3 , the mucosal unit 20 includes a first power source 21 and a mucosal wheel 22. The first power source 21 is connected to the mucosal wheel 22 to drive the mucosal wheel 22 to move along the trajectory of the first left-right direction and then the front-back direction. . In this way, the horizontal film sticking of the free end 201 of the adhesive tape 200 can be realized.

In addition, the setting of the movement track can be in the following way: the mucosal unit 20 can be located in the housing 13 of the glue supply unit 10 and the mucosal wheel 22 can extend out of the housing 13 during the mucous membrane process. Guide structures such as guide chute or guide rail are set to control the trajectory of the mucosal wheel 22. The guide chute can include a horizontal chute and an arc-shaped chute. The horizontal chute extends from left to right, and the left rear end of the arc-shaped chute It can be connected with the right end of the horizontal chute, and the arc chute extends from the back to the front first to the right and then to the left.

In order to facilitate the extension of the adhesive tape 200 after the adhesive tape 200 is cut off, a clamping mechanism 12 may be provided. Continuing to refer to Fig. 3, the gluing unit 10 also includes a clamping mechanism 12, the clamping mechanism 12 includes a second power source 121 and a clamping film part 122, and the clamping film part 122 is connected with the second power source 121 to be driven and can be Toggles between clamped and released states. Specifically, the clamping part 122 may be a retractable jaw, and the second power source 121 may drive the clamping part 122 in a horizontal direction to clamp the adhesive tape 200 protruding through the glue feeding mechanism 11 .

Further, the clamping mechanism 12 defines a second channel extending along the horizontal direction for the adhesive tape 200 to pass through. Specifically, the clamping mechanism 12 can include two clamping jaws, and the second power source 121 can drive the two clamping jaws to switch between the clamping state engaged with each other and the release state disengaged from each other, and the second channel is in the clamped state. becomes smaller and becomes larger in the released state. When the clamping part 122 is in the clamping state, the second channel is narrowed so that the adhesive tape 200 is clamped.

The clamping mechanism 12 is located between the mucous membrane unit 20 and the cutting unit 30, so that the mucous membrane wheel 22 of the mucous membrane unit 20 passes through the clamping unit to attach the adhesive tape 200 on the covering film 500, while the cutting unit 30 is arranged on the outermost The end can reduce the unnecessary loss of the tape 200, and at the same time, can make the force of the tape 200 in the tape feeding mechanism 200 and the clamping mechanism 12 more balanced, and ensure the stability of the tape 200 in the process of being pulled out.

Briefly describe the specific structure of the cutting unit 30 below, as shown in Figure 4, the cutting unit 30 includes a cutting table 31 and a cutting knife 32, the cutting table 31 is fixedly connected with the housing 13 of the gluing unit 10, and the cutting knife 32 Can be driven towards or away from the cutting table 31 to move. In addition, the cutting unit 30 may also include a power source for driving the cutting knife 32 to move. Thus, the torn film 500 and part of the adhesive tape 200 can be quickly cut off by the cutter 32, which facilitates rapid demoulding, and avoids the glue on the adhesive film 500 caused by peeling off the adhesive tape 200 from the film 500 on the adhesive tape 200. The adhesive tape 200 caused by the residue has the problem of not sticking firmly after repeated use.

The automatic film tearing device 100 according to some embodiments of the present invention also includes a fixed stand 50 (see FIG. 1 ), and the glue feeding unit 10, the cutting unit 30, and the mucous membrane unit 20 are all integrated on the glue feeding unit 10 and the three are integrated into a An integral part, the integral part is configured to be movably or rotatably connected to the fixed platform 50, and can be switched between a film-removing position and a demoulding position. Therefore, the automatic film tearing device 100 has a higher degree of modularization, which is convenient for production. Specifically, as shown in FIG. 1 , the integral part can be slidably switched between a film-removing position and a film-removing position.

In some embodiments, the automatic film tearing unit also includes a recovery unit 40, the recovery unit 40 is located at the demoulding position, the recovery unit 40 includes a recovery jaw 41, and the recovery jaw 41 is configured to be in a clamping state and a loosening state switch between. Thus, when the gluing unit 10 carries the torn film 500 and moves to the demoulding position, the recovery jaw 41 of the recovery unit 40 clamps the torn film 500, and then passes through the cutting knife 32 of the cutting unit 30. Cut the adhesive tape 200, the adhesive tape 200 and the torn film 500 can be independently clamped by the recovery jaw 41 and put into the recovery cylinder 60 set at the demoulding position, thereby realizing the recovery of the torn film 500 Recycle.

As shown in Figure 5, the recovery unit 40 also includes a third power source 42 and a base 43, and the recovery jaw 41 of the recovery unit 40 includes: a fixed jaw 411 and a movable jaw 412, and the fixed jaw 411 is fixed to the base 43 The movable jaw 412 is rotatably connected to the base 43 , and the third power source 42 is adapted to push the movable jaw 412 to move toward the fixed jaw 411 . In this way, before clamping the film 500 and when the film 500 needs to be released, the movable jaw 412 moves away from the fixed jaw 411, so that the recovery jaw 41 is in a loose state; when the film 500 enters the fixed jaw 411 and moves Between the jaws 412, the third power source 42 drives the movable jaw 412 to move close to the fixed jaw 411, so that the recovery jaw 41 is in a clamping state.

Furthermore, when the recovery jaw 41 returns to the loosened position, it can be directly driven by the third power source 42 , or it can be reset by its own gravity or an elastic member. Specifically referring to FIG. 5 , the third power source 42 is in contact with the movable jaw 412 at the back of the movable jaw 412 , and the movable jaw 412 is configured to push against the third power source 42 under the action of gravity or an elastic recovery member. Wherein, the elastic recovery member may be a spring.

In this way, the movable jaw 412 can be reset under the action of gravity by reasonably setting the position of the movable jaw 412. In addition, the elastic return member can be a spring, and the elastic return member can be activated when the third power source 42 drives the movable jaw 412. Compress and store energy, so that when the third power source 42 stops driving the movable jaw 412, the movable jaw 412 can move away from the fixed jaw 411 under the action of the elastic recovery member.

Still further, an air injection port 41a is provided inside the fixed jaw 411 and the movable jaw 412 . That is to say, the inner side of the fixed jaw 411 and the movable jaw 412 is formed as a clamping side, and the clamping side is provided with an air injection port 41 a that can inject gas in a timely manner. Because the film 500 is relatively light, the film 500 will fall out of the recovery cylinder 60 when the movable jaw 412 is released directly. Based on this, by setting the air jet 41a on the clamping side, after the movable jaw 412 is opened, the movable clamp The air injection port 41a on the inside of the claw 412 and the air injection port 41a on the inside of the fixed jaw 411 can spray air towards the film 500 to make the film 500 move towards the recovery cylinder 60 at the demoulding position under the action of the pneumatic driving force, so that the film 500 can It is collected into the recovery cylinder 60, which not only ensures the cleanliness of the working environment, but also improves the recovery efficiency of the film 500.

It can be understood that the gas supply to the gas injection port 41a can be provided through an external gas source and gas path.

Wherein, the specific structure of the power source of the second power source 121, the first power source 21, the third power source 42, and the cutting unit 30 can refer to the power source of the glue feeding mechanism, and can also be a driving motor, a hydraulic drive or Pneumatic drive parts, etc., will not be described in detail here.

The automatic film tearing system according to the embodiment of the second aspect of the present invention includes: the automatic film tearing device 100 of the above-mentioned embodiment and a controller, the controller is electrically connected to the driving mechanism of the glue supply unit 10, the cutting unit 30, and the recovery unit 40 respectively , to control the successive actions of each unit. Specifically, the driving mechanism of each unit can be the power source of each unit, such as the power source of the glue feeding mechanism 11 of the glue feeding unit 10, the power source of the cutting unit 30, the second power source 121 to the third power source mentioned above. power source42.

In this way, for some thin and soft film materials, such as peelable glue, the automatic film tearing system can complete the integration of fully automatic film tearing: taking glue → mucous film → film removal and film tearing → film recycling, removing the adhesive tape 200 after use There is basically no need for manual operation to replace and clean the recovery cylinder 60, especially for medium and large-sized products, which can effectively improve the tearing efficiency and increase production capacity; at the same time, in terms of quality, it can avoid problems that may be caused by manual tearing of the film, such as static shock wear, dust particles, dirt, scratches, etc.

In some embodiments, the automatic film tearing system further includes a film carrier 300 for carrying the film to be torn 400 , at least one of the gluing unit 10 and the film carrier 300 is configured to be movable in the vertical direction. Thus, the film lifting operation (also known as peeling off the film) can be performed before tearing off the film, which improves the first-time success rate of tearing off the film. It can be understood that the action of peeling the film can be performed before or simultaneously with tearing the film.

The following is a brief description of the automatic film tearing process of the automatic film tearing system:

As shown in FIG. 2 , the tear-off tape 200 passes through the first channel defined by the driving wheel 112 and the pressing wheel 111 , as shown in FIGS. 3 and 4 , and then passes through the cutting opening of the cutting unit 30 for automatic glue feeding. The clamping film cylinder stretches out forward, grabs the protruding rubber head, and the clamping film part 122 bites.

The mucous membrane wheel 22 presses the adhesive tape 200 to the mucous membrane position according to the preset trajectory, and the clamping part 122 is released, so that the adhesive tape 200 clamped by the clamping part 122 can be driven by the mucous membrane wheel 22 to realize the mucous membrane.

As shown in Fig. 1, the film tearing mechanism moves in conjunction with the lifting of the film carrier 300 to tear off the covering film 500 to complete the film lifting action, and controls the glue feeding unit 10 to move along the fixed platform 50 to the demoulding position to complete the film tearing action .

As shown in FIG. 5 , the third power source 42 pushes the movable jaw 412 to move toward the fixed jaw 411 to clamp the torn film. The cutter 32 acts (as shown in FIG. 4 ) to cut off the release tape 200 . The clamping mechanism 12 is opened, and the film is thrown into the recovery cylinder 60 under the action of the gas ejected from the gas injection port 41a, thus completing the film throwing (as shown in FIG. 1 and FIG. 5 ).

Providing the adhesive tape 200: the cutter 32 retreats, the drive wheel 112 rotates counterclockwise to push the peeling adhesive tape 200 forward, and the above steps are repeated.
