Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for laminating strip-shaped plated products typified by IC lead frames (hereinafter referred to as "plated products") suitable for taking them out from a plating apparatus and supplying them to a stocker for storage. It relates to an adsorption means used for the stacking.

[0002]

2. Description of the Related Art Conventionally, plated products that have been plated are taken out of the plating line and stacked horizontally in a stocker for storage in units of 50 to 100 to prepare for the next process. Since the plated product typified by the frame has a flat shape, in any case where there is no unevenness or there is slight unevenness, 1
When stacking multiple sheets in units of 0 to 100, the weight of the sheets will also help to bring the upper and lower plated products into close contact (if there is no unevenness at all) or entangle (if there is some unevenness)
Sometimes.

Therefore, when the plated products are stacked in the storage stocker, an interlayer paper is provided between the plated products not only to prevent the plated products from adhering to each other and prevent entanglement, but also to protect the plated surfaces. There is. The interlayer paper has a shape corresponding to the size of the plated product, and a paper, film, sheet or plate-shaped thin one is used.
Incidentally, the interlayer paper is not limited to paper as the material, and the resin and others are generically referred to as the interlayer paper. Therefore, in the above description and the following description, the “interlayer paper” is not limited to paper and has a broad meaning. Is what is used.

In order to interpose the interlayer paper between the plated products in the storage stocker, one plate is applied from the take-out position called unloading of the plating line, and the plated product is taken in a horizontal state by a chuck or a suction device. , Is directly dropped on the stocker for storage, is dropped and stored therein, and another sheet is similarly dropped from the interlayer paper stocker by another suction device to be dropped and stored. This operation is repeated to successively stack the plated products with the intercalation paper interposed.

[0005]

However, when the intercalation paper is dropped and stored in the storage stocker as described above, the intercalation paper is thin and lighter than the plated product even if the fall distance is not so large. For some reasons, some of the inter-layer papers that are being stored may not be positioned correctly in the storage stocker, or the corners of the inter-layer paper may hit the wall of the storage stocker and interfere, or the corners may be bent or stored. It may project outside from the gap of the stocker. In such a case, there is a problem that the next plated product laminated on the interlayer paper may not be properly stored and may be bent or deformed.

[0006]

According to the present invention, the strip-shaped plated product is held in a horizontal state by the suction means, and is guided to the interlayer paper stocker before being supplied to the storage stocker, and the uppermost interlayer paper Place the strip-shaped plating on the top, adsorb the inter-layer paper together for each strip-shaped plating with the same suction means and take it out from the inter-layer paper stocker. Inside the storage stocker with the inter-layer paper positioned on the lower surface It is a stacking method that drops and stacks on top of each other.

[0007] In order to carry out such a lamination treatment of the plated products, as a suction means used for laminating the strip-shaped plated products, an appropriate transfer means is used to take out the strip-shaped plated products, the interlayer paper stocker, and the storage space. The stocker is capable of moving back and forth between the stockers, and is provided with a base plate having a suction system connected to an air suction device, and a suction plate attached to the base plate. The suction means was provided with a suction hole and a second suction hole for suctioning the interlayer paper.

[0008]

Operation: First, the strip-shaped plated product is held in the horizontal state by the suction means and taken out from the take-out position of the strip-shaped plated product, and is guided to the interlayer paper stocker before being supplied to the storage stocker. Then, the strip-shaped plated product is positioned on the uppermost inter-layer paper in the inter-layer paper stocker, and the inter-layer paper is adsorbed together for each strip-shaped plated product by the same suction means and taken out from the inter-layer paper stocker. In this way, the inter-layer paper is transferred directly above the storage stocker as if they were stacked on the underside of the plated product, and the adsorption is released to drop the plated product together with the inter-layer paper into the storage stocker. It will be done.

In order to carry out such a lamination process of the plated products, an adsorbing means is used which can move freely between the take-out position of the strip-shaped plated products, the interlayer paper stocker and the storage stocker by an appropriate transfer means. . If suction is applied from the air suction device through the suction system, the first suction hole of the suction plate is provided at a position corresponding to the non-opening portion of the plated product, so that the suction plate can be simply applied to the upper surface of the plated product. The first suction hole adsorbs the plated product.

Next, when the plated product is placed on the uppermost interlayer paper in the interlayer paper stocker while the plated product is adsorbed, the second suction hole of the adsorption plate becomes the opening of the plated product. Since it is provided at the corresponding position, the second suction hole adsorbs the interlayer paper under the plated product through the opening. When transferred to the storage stocker in this state and releasing the suction, the interlayer paper is dropped and stored in the storage stocker as it is without causing misalignment by utilizing the self-weight of the plated material on top of it. Will be.

[0011]

Embodiments will be described below with reference to the drawings. Figure 1
1 schematically shows the corresponding positional relationship between the take-out position 1 of the plated product, the interlayer paper stocker 2 and the storage stocker 3 and the transfer locus of the suction means 4. When the plating process is completed, one IC lead frame 5 (hereinafter referred to as a “plated product”) is transferred to a take-out position 1 of the plated product at the end of the plating line by an appropriate transfer means and transferred. The interlayer paper 6 is prepared in units of 10 to 100 sheets in a state of being laminated in the interlayer paper stocker 2 in advance, and the interlayer paper stocker 2 and the storage stocker 3 are provided on the left and right of the plated product take-out position 1. It is positioned.

The transfer path of the suction means 4 is first transferred to the pick-up position 1 of the plated product by utilizing an appropriate transfer means, and one frame 5 is horizontally held and sucked there (track A). Next, the sheet is transferred directly above the inter-layer paper stocker 2 and the inter-layer paper 6 is also adsorbed to the frame 5 while the frame 5 is adsorbed (trajectory B). Further, the frame 5 is transferred to a position directly above the storage stocker 3 and the suction is released there, so that the frame 5 together with the interlayer paper 6 is dropped and stored (trajectory C). This operation is repeated.

The suction means 4 is mainly composed of a base plate 11 in which suction systems 9 and 10 are connected to an air suction device 8 and a suction plate 13 which is attached to the base plate 11 through a fastening metal fitting 12 so as to be exchangeable. . The base plate 11 is connected to the actuator 1 via the holder 14.
5, the suction plate 13 can be pressed against the upper surfaces of the frame 5 and the interlayer paper 6. Suction system 9, 1
0 communicates with the first suction hole 18 and the second suction hole 19 of the suction plate 13 through the through holes 16 and 17 formed in the base plate 11 and the suction plate 13, respectively.

The first suction holes 18 are provided at positions corresponding to the non-opening portions 20 on both sides of the frame 5, and the second suction holes 19 are provided at positions corresponding to the slit-shaped opening portions 21. There is. Since the positions of the non-opening portion 20 and the opening portion 21 may differ depending on the type of the frame 5, a plurality of suction plates 13 in which the opening positions of the first suction holes 18 and the second suction holes 19 are changed according to the types are prepared. Then, an appropriate suction plate 13 is attached to the base plate 11 in an exchangeable manner by operating the tightening member 12 according to the type of the frame 5 to be sucked.

Next, the operation of the suction means 4 will be described. When the suction means 4 is first transferred to the plating article take-out position 1 by utilizing an appropriate transfer means, the air suction device 8 is moved here.
Through the suction system 9 and the through hole 16 to operate the first suction hole 18
Then, one frame 5 is horizontally held and attracted. Next, the suction means 4 is moved to a position right above the interlayer paper stocker 2 by the same transfer means, and the frame 5 is sucked together with the frame 5 onto the uppermost interlayer paper 6 in the interlayer paper stocker 2.
Then, the air suction device 8 is actuated, and the second suction hole 19 is sucked through the suction system 10 and the through hole 17 to suck the interlayer paper 6 while the frame 5 is sucked.

Further, the suction means 4 is provided directly above the storage stocker 3.
Is transferred and the suction is released there, the frame 5 is dropped together with the interlayer paper 6. At this time, both the first and second suction holes 18 and 1 are provided through the suction systems 9 and 10 and the through holes 16 and 17.
If air blowing is performed instead of suction from 9, the interlayer paper 6 and the frame 5 are easily separated from the suction plate 13. Since the frame 5 is positioned above the interlayer paper 6 when it is dropped, the interlayer paper 6 does not move out of alignment with the frame 5 and drops to a correct position directly below the suction plate 13 and inside the storage stocker 3 for storage. Is stored in. By repeating this operation, the frames 5 are sequentially stacked with the interlayer paper 6 interposed therebetween.
There is no displacement of position. In the above description, the "unloading process" for taking out the frame 5 from the plating line has been mainly described, but by performing the above operation in reverse, the "loading process" for supplying the frame 5 to the plating line is performed. Is also sufficiently applicable.

[0017]

As described above, according to the present invention, the interlayer paper also attracts the intercalation paper while adsorbing the electroplating product by the same adsorption means, and when laminating the layers, the intercalation paper is placed on the lower side and the electroplating product is placed on the upper side. Since it will be dropped and stored as it is,
Since the plated product is heavier than the interlayer paper and drops faster, the interlayer paper is guided by the plated product and drops at the same time. In addition, the corners of the interlayer paper do not interfere with the wall surface of the storage stocker, and even if a large number of plated products are stacked in the storage stocker, even one plated product is not bent or deformed. effective.
