Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a fixed-length lead frame for mounting thin, minute, and easily deformable electronic components that is stacked and stored in a tray in an upright position. Regarding a lead frame arranging device.

[Prior Art] To facilitate handling, standard-length lead frames formed by punching with a press or the like are generally stored or transported in a stacked state of a predetermined number.

A sorting device that automatically stacks these standard length lead frames has been developed and used in the past. This sorting device stacks standard-length lead frames horizontally.The standard-length lead frames, which are formed by punching with a press and transported on a conveyor, are carried onto a horizontally facing slider, and then the standard-length lead frames are stacked horizontally. It has a structure in which standard-length lead frames are stacked one after another horizontally by repeating the process of rotating the slider downward and causing the standard-length lead frames carried onto the slider to fall below the slider due to their own weight. .

[Problems to be Solved by the Invention] Nowadays, lead frames have a structure that is extremely thin, lightweight, and easily deformed. By the way, if we talk about a recent example of a lead frame 10 as shown in FIGS. 4 and 5, the plate thickness is extremely thin at 0.08 mm, and the lead width and pitch between the leads are 0. There are those with extremely small widths and small intervals, such as .10 mm and 0.20 mm. In addition, the lead 101 in a cantilevered state of the lead frame is bent downward in a two-shape shape, and the lead 101 and its stage (not shown) are easily deformed downward. There is. In addition, L-shaped legs 102 are provided on both sides of the lead frame 10 and extend downward, so that when a plurality of lead frames 10 are stacked as shown in FIG. The legs 102 on both sides are other lead frames 10
There are some things that are easy to get caught on.

Therefore, the easily deformable lead frame 10 as described above
If these are stacked horizontally using the conventional sorting device described above, the leads 101 of the lead frame, the stage, etc. will gradually bend downward due to their own weight and become deformed.

Furthermore, if the conventional alignment device described above is used to stack the thin and light standard-length lead frames 10, when the slider of the alignment device is rotated downward to drop the standard-length lead frames 10 below, In this case, the light standard-length lead frame 10 receives wind pressure from its surroundings and is reversed or its direction is tilted. The standard length lead frames IO are piled up unevenly and sloppily because some of them get caught and tangled.

Therefore, the conventional alignment device described above cannot be used for the lead frame 10, which is light and easily deformed.

The present invention was made in view of such problems, and its purpose is to provide a set of standard-length lead frames that are light and easily deformable and can be stored in a tray by neatly stacking the standard-length lead frames without deformation. Our objective is to provide a device (hereinafter simply referred to as an assortment device).

In the arrangement apparatus having the above-mentioned configuration, the tray 12 is moved by a pair of front and rear upstanding walls 14a on the table 14.

It will be installed within 14b. Then, by driving the air cylinder 32 of the rotation means 20 and pushing the drive rod 34 forward, the tilting table 16 connected to the tip of the rod 34 is rotated about its rotation axis 30.
The tilting table 16 and the movable table 14 are tilted at 45 degrees with respect to the horizontal direction, for example. And moving table 1
The tray 12 mounted on the tray 12 is tilted at an angle of 45 degrees with respect to the horizontal direction. At the same time, the camshaft drive motor 506 is driven to rotate the camshaft 503 in a predetermined direction. Then, the support member 42 connected via a rod-shaped link 511 to the tip of a lever 509 that contacts the peripheral surface of one cam 502 rotating together with the cam shaft 503 via a cam roller 507 is rotated around the shaft 40 by a predetermined angle, and the side While the clamper 26 is oriented horizontally, the tip of the lever 508 that contacts the circumferential surface of the other cam 501 rotating together with the camshaft 503 via the cam roller 507 is separated from the rear end of the support arm 44, and the side clamper 26 is moved.

1. Clamp between the inner and lower surfaces. Then, as shown in FIG. 3, the tip clamper 24 that has clamped the tip of the standard length lead frame 10 is caused to pass over the slider 261 of the side clamper by the tip clamper moving means 240 by driving the motor 248. , to a predetermined position ahead of the conveyor 22, thereby conveying the standard length lead frame 10 to a predetermined position ahead of the conveyor 22.

Then, the standard length lead frame 10 is completely removed from the conveyor 22 and the standard length lead frame 10 is removed.
is mounted at a predetermined position on the slider 261'' of the side clamper. Next, the side portion of the regular length lead frame 10 mounted at a predetermined position on the slider 261-4= is clamped to the side clamper 26.

Specifically, the air cylinder 263 is driven to lower the side chuck 262 of the side clamper, and the side portion of the standard length lead frame 10 is moved between the slider 261 on which the standard length lead frame 10 is mounted and the side chuck 262. Clamp between. Thereafter, the air cylinder 243 is driven to raise the chuck 242 of the tip clamper upward, and the tip of the regular length lead frame 10 is separated from the tip clamper 24. Next, the camshaft motor 5

is slid along with the side clamper 26 a predetermined distance in front of the support member 42 against the elastic force of the coil spring 46. Then, the side clamper 26 is inserted into the tray 12 on the movable table 14, which is tilted at 45 degrees, together with the regular length lead frame IO whose side portions are clamped, in an upright state from the upper opening thereof. Then, the standard length lead frame 10, which is light and susceptible to wind pressure, can be neatly inserted into a predetermined position in the tray 12 in an upright position in a predetermined direction without inverting or tilting it.

Next, the air cylinder 263 is driven to raise the side chuck 262 of the side clamper, and the side portion of the regular length lead frame 10 inserted into the tray 12 is removed from the side clamper 26.

At the same time, one of the cams 501 rotating together with the camshaft 503 rotates the lever 508 that contacts the circumferential surface of the cam 501 via the cam roller 507 around the shaft 510, so that the tip of the lever 508 is placed behind the support arm 44. The support arm 44 is separated from the end, and the support arm 44 is moved together with the side clamper 26 by utilizing the elastic force of the coil spring 46 to move the support member 42.
Slide the top to the rear and pull out the side clamper 26 from inside the tray 12 above it. At the same time, the other cam 502 rotating together with the camshaft 503 rotates the lever 509, which contacts the circumferential surface of the cam 502 via the cam roller 507, around the shaft 510, and attaches a rod-shaped link 511 to the tip of the lever 509. The support member 42 connected thereto is rotated around the shaft 40, and the support member 42 is rotated back in the horizontal direction together with the side clamper 26. Then, the standard-length lead frame 10 released from the side clamper 26 is dropped into the tray 12, which is tilted at 45 degrees due to the weight of the lead frame 10, to the lower side of the tray 12. Thereafter, by sequentially repeating the above steps, the regular length lead frames 10 are stored in an upright state in the tray 12 which is in the inclined state.

Further, when storing the standard length lead frames 10 in order in the tray 12 that is tilted at 45 degrees as described above, the moving table 14 on which the tray 12 is mounted is rotated by the table motor 185 of the moving means 18 at a predetermined position. The tilting table 16 is driven at a specific timing to move the tilting table 16 backward by a predetermined pitch from the front to the rear thereof. This pitch amount is equal to the height of the standard length lead frame 10 (standard length lead frame 10
However, if the leg 102 etc. are not extended below it and it is in the shape of a flat plate, the thickness of the standard lead frame 10)
shall be. Then, as described above, the side clamper 26
is inserted into the tray 12 tilted at 45° together with a regular-length lead frame IO whose sides are clamped, while moving from the lower side to the upper side by a predetermined pitch. Then, the standard-length lead frame 10, whose side portions are clamped by the side clamper 26, is dropped a very short distance inside the tray 12 to the lower side of the lead frame 10, in a so-called drop-down manner, to form a standard-length lead frame 10 that is light and susceptible to wind pressure. The length lead frames 10 can be stacked and stored in the tray I2 in an upright state from the lower side side to the upper side side without being inverted or tilted.

Next, after the tray 12 is filled with the standard-length lead frames 10 stacked and stored in an upright state, the movable table 12 on which the tray 12 is mounted is moved using the rotating means 20. Return to horizontal direction. Specifically, the air cylinder 32 of the rotation means 20 is driven to move the drive rod 34 backward. And the drive rod 34
The tilting table 16 connected to the tip is rotated around its rotation axis 30, and the tilting table 16 is returned to the horizontal direction together with the movable table 14 on which the tray 12 is mounted.

A pair of upright walls 148 on the front and rear of the moving table 14
．． The tray 12 containing the standard length lead frame IO is taken out from within the gap 14b and outward from the side thereof. Next, a new empty tray 12 is mounted again between the pair of front and rear upright walls 14a and 14b on the moving table 14, and the above steps are repeated in sequence.

Then, the regular length lead frames IO can be stored one after another in the tray 12 in an upright state, stacked one on top of the other in an orderly manner.

Furthermore, when storing the standard length lead frame 10 in the tray 12 as described above, the standard length lead frame 1O may be inserted into the tray 12 at an angle of 45 degrees, or the standard length lead frame 10 may be placed at a 45° angle. Since the leads 101 of the standard-length lead frame 10 and its stage are stored on top of each other in an inclined state or in a vertically standing state, only a load of around 70% or less of their own weight is applied downward. In this way, the regular length lead frames 10 can be stacked and stored in the tray 12 without being deformed downward.

In the above-mentioned embodiment, as shown in FIG. When storing a small number of standard-length lead frames 10 in the tray 12, the small number of standard-length lead frames 10 are stacked on top of each other in the tray 12 using the partition wall 121 to ensure that they do not fall down. It's good to be able to store it. At the same time, by leaning a large number of regular-length lead frames 10 stored in the tray 12 against the partition wall 121 one by one, the regular-length lead frames 10 are stored in the lower side of the inclined tray 12. frame 10
It is possible to accurately prevent the lead frame from deforming due to the load from another standard length lead frame 10 superimposed on the upper side thereof.

In the above embodiment, the side clamper moving means 28 for inserting the side clamper 26 clamping the side portion of the standard length lead frame 10 into the tray 12 and pulling it out from the tray 12 is an air cylinder or a servo motor. It may also be formed using a mechanism using a motor as a drive source.

[Effects of the Invention] As explained above, in the arranging device of the present invention, when the light and finely deformable standard length lead frames are stacked and stored in a tray, the standard length lead frames are not tilted diagonally upward or downward. By standing upright in the direction or perpendicular direction, only a load less than a few fractions of its own weight is applied to the easily deformable cantilevered leads and stage of the standard length lead frame.

Therefore, according to the arranging device of the present invention, the standard length lead frames can be stacked and stored in the tray without deforming the easily deformable leads, stages, etc. of the standard length lead frames downward due to their own weight.

Furthermore, in the sorting device of the present invention, when stacking and storing standard-length lead frames in a tray, the standard-length lead frames, which are light and easily affected by wind pressure, are allowed to fall over long distances due to their own weight. After forcibly inserting the standard-length lead frame into the tray together with the side clamper, the standard-length lead frame is released from the side clamper, and the inside of the tray is moved a short distance to the lower side of the tray by its own weight. By dropping the standard length lead frame into the tray, the standard length lead frame is stored in an upright state in the tray.

Therefore, according to the sorting device of the present invention, it is possible to invert, tilt, or intertwine a part of a flat lead frame that is light and susceptible to wind pressure, or a standard lead frame that has legs, etc. They can be neatly stacked and stored in a tray standing upright.
