Description

[Detailed description of the invention] The present invention is a method for plating a plurality of plating objects, particularly strip-shaped plating objects such as IC lead frames (hereinafter simply referred to as "plating objects"), for supplying or discharging them to a line of a plating device. This relates to a storage device that stores items in a stacked state.

When plating IC lead frames and other strip-shaped materials, in order to increase the processing efficiency of the plating device as a whole, it is necessary to supply the plating device line with multiple strip-shaped materials piled up in advance. It is necessary to efficiently load and unload the plating material to the so-called plating device by taking out and storing the plating material discharged from the plating device line in a stacked state. As a conventional storage device for this purpose, for example, a box-shaped storage device is known. This box-shaped storage device had an opening at the top, a side wall around the periphery, and a bottom. When in use, this box-like storage device is placed on the frame or base plate, and the plating items are stacked and stored in a quadrilateral shape defined by the bottom and side walls. However, in the case of such conventional storage devices, the upper opening and the side walls on the four sides are formed to a certain size so that it can only accommodate plated items of a certain size, so it cannot accommodate plated items of a larger size. In the case of smaller size plated items, excess space remains within the side walls surrounding the four sides, resulting in uneven stacking of the plated items in the storage device. At the same time, the bottom is in a so-called deep state, so when using this storage device to take out plated items, for example, the plated items are dropped from the upper opening toward the deep bottom, and the plated items are removed. There was a problem that it was difficult to store it accurately because it bent or got stuck on the side wall.

The present invention was developed in view of these points, and its structure is such that a pair of left and right support plates are placed facing each other and erected on the plane of the base so that the interval can be freely adjusted. By arranging and partitioning the support plates, and by placing a table between both support plates that can be raised and lowered freely, it is possible to freely store matted items of different sizes, and always store them at a certain level. Storage of strip-shaped plating objects that can be set on a surface to facilitate taking in and storing plating objects from the plating device line terminal into the storage device, or supplying and taking out the plating objects from the storage device to the plating device line. The gist is that it is a device.

The present invention will be described in detail below based on an embodiment shown in the drawings. 1 to 3 are views showing one embodiment of the present invention, and the illustrated storage device for plating items mainly includes a base 1, support plates 2 and 3,
It consists of a stopper plate 4 and a table 5. In the illustrated example, the base 1 is plate-shaped, but the base 1 is not limited to this, and it goes without saying that it may be frame-shaped or other shapes. The support plates 2 and 3 are a pair of left and right support plates that are opposed and erected on the plane of the base 1 with an adjustable interval. In order to be able to freely adjust the spacing, the support plates 2 and 3 are provided with flat bases 6 and 7 whose vertical cross section is L-shaped, and through holes are bored therein and adjuster bolts 8 are attached thereto. I have to. In the illustrated example, the adjusting bolts 8 are provided at four locations, two each on the bases 6 and 7 of the pair of left and right support plates 2 and 3, but the position and number of adjusting bolts 8 may be freely determined. It is not specific to this example. The lower end of the adjusting bolt 8 can be screwed into a tightening nut 10 that is previously placed in a groove 9 formed in the base 1. Through-holes 11 and 12 are formed in the centers of the support plates 2 and 3, respectively, and a sensor 13 is arranged at the same level as the through-hole. In the illustrated example, the sensor 13 is a phototube element. The surface position of the plating object 14 used for plating on the table 5 at the stacking height can be checked at all times or periodically. Incidentally, the upper ends of the support plates 2 and 3 are sloped 15 and 16, respectively, and are inclined inward to easily receive the plating material 14. The stopper plate 4 is arranged so as to partition the vicinity of the front ends of the support plates 2 and 3, and can be adjusted in position as appropriate by a positioning means (not shown). The table 5 is arranged between the support plates 2 and 3 so as to be able to be raised and lowered by a pressure cylinder 17. Although not shown in the drawings, if the spacing between the support plates 2 and 3 is adjusted to make them wider, a rug plate corresponding to the appropriate width is placed on the top surface of the table 5.

Next, the effect will be explained. For convenience of explanation, this plating object storage device is placed near the line terminal 18 of the plating device as shown in FIG.
A case will be described in which the plated material 14 discharged from 8 is taken out and stored. Metallic item 1
4 is assumed to flow out from the line terminal 18 of the plating device in the direction of the arrow in FIG. 1, and is stored in this storage device.
The table 5 is raised and lowered to an appropriate height using a pressure cylinder 17 in accordance with the pass line of the plated object formed by rollers 19 provided at the table 8. In such a state, the plating object 14 that is fed in from the direction of the arrow in FIGS. 1 and 2 is forwardly positioned by the stopper plate 4 if there is speed at the time of feeding, and is also moved between the pair of left and right support plates. The left and right sides are placed on the table 5 by regulating their positions. Then, the plating objects 14 that are successively discharged from the line terminal 18 of the plating device in which such a state continues one after another are positioned on top of the previous plating object, thus obtaining a stacked state of a predetermined number of sheets. The sensor 13 constantly checks the level height of the top surface of the plated items 14 that are piled up, and if the table 5 positions, for example, a single piece of plated item 14 between the support plates 2 and 3 and stores it, the plated item 14 can be stored. The plated object 1 formed by the roller 19 lowers the table 5 in accordance with the thickness of one sheet of 14.
The table 5 is always positioned at a level height that is easy to take in from the pass line 4, and care is taken to prevent the plating object 14 from bending or hitting the mating part. In such a state, if the size of the plating object 14 changes from large to small, the adjuster bolt 8 should be loosened from the tightening nut 10 in advance, and the support plates 2 and 3 should be tightened in the horizontal direction [in the figure]. The distance is adjusted in the direction of the arrow X, and the distance in the left and right direction is set to be small or large, and the objects are positioned there. Also, in the front-back direction [arrow Y in the figure]
When the length of the plating object 14 becomes small or large in the direction of plating, the length of the support plates 2 and 3 in the front-rear direction is set in advance to match the minimum length of the plating object, Objects can be dealt with by changing the position of the stopper plate 4. In the illustrated example, the stopper plate 4 is shown to partition the entire front end of the support plates 2 and 3, but there is no need to do so; It is sufficient to arrange the stopper plate 4 so that it is present only in that position. In addition, in the illustrated example, the stopper plate 4
Although it was explained that the position is simply variable, it would be more convenient if the stopper plate 4 could be freely removed from that position when receiving and storing a predetermined number of plated objects 14 is completed, and the front of the support plates 2 and 3 can be opened. This makes it possible to easily take out the stacked plating material 14 from there for subsequent processing. Furthermore, although it has been explained that the spacing between both of the support plates 2 and 3 can be adjusted freely by tightening or loosening the adjuster bolts 8, the spacing can be adjusted as desired if at least one of the supporting plates is adjustable in position. However, both support plates 2 and 3 do not necessarily have to be variable in position. In addition, when this plating object storage device is arranged to supply the line plating objects 14 of the plating device, the table 5 is positioned in advance at the lowest position and a predetermined number of plating objects are placed between the support plates 2 and 3. 14 are set in a stacked state, and each time the top plated material 14 is taken out by an appropriate means such as a vacuum device or the like and supplied to the line of the plating device, the pressure cylinder 17 is constantly pumped by the thickness of the taken out plated material 14. It is only necessary to raise the table 5 through the plate and adjust the height so that the surface level of the topmost plated object 14 is always at a level at which it can be easily taken out to the line of the plating device.

As explained above, the storage device for strip-shaped plated objects according to the present invention has a pair of left and right support plates facing each other and erected on the plane of the base so that the interval can be freely adjusted, and a stopper plate near the front end of both support plates. Since the structure is such that a table that can be raised and lowered is placed between both support plates, it is possible to accept plated items of different sizes and stack and set a predetermined number of them by adjusting the distance between the pair of left and right support plates. By adjusting the height position of the table, it is possible to always obtain a height that makes it easy to store the plated items between the pair of left and right support plates. This has the effect that it can be reliably stored between the support plates without getting stuck. Furthermore, by making the table movable up and down, this storage device for strip-shaped plated items can be installed at the line terminal of the plating equipment and used to receive plated items and stack and store a predetermined number of pieces, or on the line of the plating equipment. There is also the additional effect that it can be used in both ways, such as placing a predetermined number of sheets of plating material on top of each other and making it easier to take out and supplying the plating material.
