Description

The present invention relates to a clamp tray capable of gripping and fixing a work.

For example, when printing a plurality of works simultaneously, supplying the works to a mounting machine, or bonding a semiconductor work, it is required to position and fix the works with high accuracy.

To meet such demands, various clamp trays have been proposed so far. For example, in Patent Document 1, plate-shaped members such as bottom plates 8 and 9 (lower plate), frame plate 10 (frame plate), and upper plate 11 (upper plate) are stacked and fixed, and a spring is used. A jig (clamp tray) in which 6 and the movable plate 3 are arranged inside the frame plate 10 is disclosed. In this clamp tray, it is possible to appropriately hold and fix the work by moving the movable plate.

In order to fix each plate-shaped member to form a strong clamp tray, it is necessary to obtain high fixing strength between each member. As one of the ideal methods for achieving this, a method of fixing members by thermocompression bonding can be considered. If this method can be used, the members can be firmly fixed to each other on the surface by a relatively simple process, and a sufficiently high fixing strength can be obtained as compared with the case of screwing or spot welding.

However, particularly when the thermocompression bonding is performed in a state where the movable parts (the spring 6 and the movable plate 3 correspond in the above example) are included, the movable parts are fixed to other members and do not function properly. I will end up. Therefore, it is generally difficult to form the clamp tray by utilizing thermocompression bonding.

However, the content of the present invention is not limited to these embodiments. In the following description, the up-down, left-right, and front-rear directions (directions orthogonal to each other) are as shown in FIG. 1 and the like.

1. First Embodiment First, a first embodiment of the present invention will be described. FIG. 1 is a schematic external view of a clamp tray 1 (hereinafter, also referred to as “clamp tray 1”) according to the present embodiment. In the clamp tray 1, the upper plate 11, the frame-shaped plate 12, the first lower plate 13, and the second lower plate 14 are stacked in order from the top, and the movable plate 15 is inserted into the frame-shaped plate 12. The configuration has been changed (see FIG. 7).

As a whole, the clamp tray 1 is a thin plate-like body having a rectangular shape in a plan view (the longitudinal direction is the longitudinal direction) with the vertical direction being the thickness direction. The overall size of the clamp tray 1 is, for example, about 20 cm in the front-rear direction, about 4 cm in the left-right direction, and about 1 mm in the up-down direction (thickness). It should be noted that various shapes of the clamp tray 1 in plan view can be adopted, such as one having a different width (size in the left-right direction) as shown in FIG.

In addition, as shown in FIG. 1, the clamp tray 1 includes a plurality of (10 in the example of the present embodiment) housing holes H arranged at equal intervals in the front-rear direction, and a front side positioning hole Pa provided on the right front side. , A rear side positioning hole Pb provided on the left rear side, and a recess DP provided at the center of the rear end.

The accommodation hole H is a hole for accommodating a work (a chip or the like may be used), and penetrates in the vertical direction. The front and rear positioning holes (Pa, Pb) are holes used for positioning in the forming process of the clamp tray 1, and the usage method will be apparent from the description below. In the depression DP, a part of the movable plate 15 (pressed portion DX described later) is projected rearward so that the movable plate 15 can be pushed and moved forward.

Next, each plate member (11 to 15) that is a constituent member of the clamp tray 1 will be described in more detail. Each plate member (11 to 15) is formed by, for example, etching using a thin plate made of a metal material (for example, stainless steel material such as SUS304).

FIG. 2 is a schematic configuration diagram of the upper plate 11. As shown in the figure, the upper plate 11 has a configuration in which a through hole 112, a housing hole H, front and rear positioning holes (Pa, Pb), and a recess DP are provided in a substantially rectangular thin plate portion 111. The through hole 112 is a hole used when spot welding the movable plate 15, and the method of use will be apparent from the description below.

FIG. 3 is a schematic configuration diagram of the frame-shaped plate 12. As shown in the figure, the frame-shaped plate 12 includes a left side portion 121L extending in the front-rear direction, a front side portion 121F extending rightward from a front end portion of the left side portion 121L, and a right end portion of the front side portion 121F extending rearward. It has a right side portion 121R. The frame-shaped plate 12 plays a role of ensuring a space for disposing the movable plate 15 inside the clamp tray 1.

The rear side of the space SP (between the rear end of the left side portion 121L and the rear end of the right side portion 121R) surrounded by the left side portion 121L, the front side portion 121F, and the right side portion 121R is an opening OP that is opened rearward. Is becoming When the plate members (11 to 15) are vertically stacked, the accommodation holes H and the front and rear positioning holes (Pa, Pb) pass through the space SP of the frame-shaped plate 12.

FIG. 4 is a schematic configuration diagram of the first lower plate 13 (one of the lower plates). As shown in the figure, the first lower plate 13 has a configuration in which an accommodation hole H, front and rear positioning holes (Pa, Pb), and a depression DP are provided in a substantially rectangular thin plate 131.

FIG. 5 is a schematic configuration diagram of the second lower plate 14 (one of the lower plates). As shown in the figure, the second lower plate 14 has a configuration in which a through hole h, each positioning hole (Pa, Pb), and a depression DP are provided in a substantially rectangular thin plate 141. In the present embodiment, the through hole h is formed in the second lower plate 14 due to the shape of the workpiece to be fixed, but the through hole h may be omitted in the basic configuration of the present invention.

FIG. 6 is a schematic configuration diagram of the movable plate 15. As shown in the figure, the movable plate 15 has a movable portion 151, a fixed portion 153, a left spring portion 154L, and a right spring portion 154R. The movable portion 151 is provided with a housing hole H, a front side positioning hole Pa, a rear side positioning hole Pb, and a pressed portion DX. The pressed portion DX is provided at a position corresponding to the depression DP of another plate member.

Further, the grip portion 151a, which is a part of the movable portion 151, plays a role of gripping the work as described later, and is provided so as to project rearward from the front edge of each accommodation hole H. The fixed portion 153 is connected to the movable portion 151 via the left and right spring portions (154L, 154R) on the rear side of each accommodation hole H (excluding the rearmost one). The left and right spring portions (154L, 154R) have a meandering shape so as to elastically expand and contract in the front-back direction.

The upper plate 11, the frame plate 12, the first lower plate 13, and the second lower plate 14 have the same dimensions in the front-rear direction and the left-right direction. Therefore, these plate members (11 to 14) can be vertically stacked so that their outer edges are overlapped with each other.

On the other hand, the front-rear dimension of the movable plate 15 is substantially equal to the front-rear dimension of the space SP provided in the frame-shaped plate 12. The lateral dimension of the movable plate 15 is slightly smaller than the lateral dimension of the space SP. The thickness (vertical dimension) of the movable plate 15 is slightly smaller than that of the frame-shaped plate 12. Accordingly, the movable plate 15 can be stored in the space SP.

Next, the forming process of the clamp tray 1 will be described with reference to FIG. 7. The numbers in parentheses in FIG. 7 indicate the order of forming steps.

First, the upper plate 11, the frame-shaped plate 12, the first lower plate 13, and the second lower plate 14 are sequentially stacked so that their outer edges overlap each other. Then, the plate members (11 to 14) are thermocompression-bonded to each other by heating the plate member while pressing the plate member in the vertical direction to form the main body portion X of the clamp tray 1 (component before mounting the movable plate 15).

By this thermocompression bonding, the plate members (11 to 14) can be firmly fixed to each other on the surface, and a sufficiently high fixing strength can be obtained as compared with the case of screwing or spot welding. Further, thermocompression bonding can be realized by a relatively simple process, which is advantageous from the viewpoint of production efficiency. Furthermore, since the movable plate 15 is not used in the thermocompression bonding process, the movable plate 15 is not affected by pressurization or heating by thermocompression bonding. At the rear end portion of the main body portion X formed by thermocompression bonding, the space SP communicates with the outside through the opening OP.

Next, the movable plate 15 is inserted into the space SP via the opening OP. When the movable plate 15 is completely inserted, the fixed portions 153 provided on the movable plate 15 are exposed upward through the through holes 112 provided on the upper plate 11. Further, in this state, the front side positioning hole Pa and the rear side positioning hole Pb of each plate are vertically overlapped with each other. Therefore, the movable plate 15 is positioned in this state by inserting rod-shaped pins into these positioning holes.

After positioning the movable plate 15 in this manner, spot welding is performed on each of the fixed portions 153 exposed above to fix each fixed portion 153 (movable plate 15) to the first lower plate 13. As a result, the movable plate 15 is attached to the main body X, and the clamp tray 1 is completed. The form of attaching the movable plate 15 to the main body X is not limited to the spot welding as in the present embodiment, but may be attached by using, for example, screwing or using a magnet.

As described above, the movable plate 15 is inserted into the main body X and then fixed to the main body X by spot welding at each fixed portion 153. Therefore, the portions of the movable plate 15 other than the fixed portions 153 (the movable portion 151, the left-side spring portion 154L, and the right-side spring portion 154R) are not fixed to the main body X and the movability is maintained. As a result, the clamp tray 1 can appropriately grip the work by moving the movable portion 151 in the front-rear direction.

8A and 8B show, as an example of variations regarding the shape of the clamp tray 1 in plan view, one having a relatively narrow width (size in the left-right direction) (first form) and one having a relatively wide width (second form). Is shown. Note that FIG. 9 shows a cross-sectional view of a portion indicated by AA in FIG. 8 and an enlarged view of a part B of the cross-sectional view.

10 shows an internal configuration diagram of a portion C shown in FIG. 8, and FIG. 11 shows an internal configuration diagram of a portion D shown in FIG. The clamp tray 1 shown in FIGS. 10 and 11 is in a state in which the pressed portion DX projects from the depression DP of the clamp tray 1 (a state in which no external force is applied).

Next, the operation of the clamp tray 1 for gripping and fixing the work will be described.

In the depression DP of the clamp tray 1 in the initial state (the state in which no external force is applied), as shown in FIG. 11, the pressed portion DX at the rear end of the movable portion 151 projects rearward. Further, in the initial state, the rear end portion of each grip portion 151a projects into the accommodation hole H, and the accommodation hole H is narrowed. When the pushed portion DX is pushed forward in this initial state, the movable portion 151 moves forward against the bias of the left and right spring portions (154L, 154R).

When the movable portion 151 moves forward, the rear end portion of each grip portion 151a must move from the position overhanging to the accommodation hole H as shown in FIGS. become. As a result, each accommodation hole H is expanded, and it becomes possible to accommodate a work having a size slightly smaller than the accommodation hole H. The position of the movable portion 151 at this time can be regarded as a storable position at which a work can be stored through the storage hole H of the upper plate or the lower plate.

When the work is completely stored in the storage hole H in this state and the pressing of the pressed portion DX is released, the movable portion 151 is biased rearward by the left and right spring portions (154L, 154R). As a result, the grip portion 151a pushes the work backward so as to return to the initial position, and the work is sandwiched between the grip portion 151a and the rear edge of the accommodation hole H. The position of the movable part 151 at this time can be regarded as a fixed position for pressing and fixing the accommodated work. In this way, the clamp tray 1 can appropriately hold and fix the work.

In addition, in order to cancel the gripping and fixing of the work, the pressed portion DX may be pressed forward again. When the pressed portion DX is pressed forward, the grip portion 151a moves forward, the accommodation hole H expands, and the work can be removed from the clamp tray 1.

2. Second Embodiment Next, a second embodiment of the present invention will be described. The second embodiment is basically the same as the first embodiment except for the configuration of the accommodation hole H and the movable plate 15 and the like around the accommodation hole H. In the following description, emphasis is placed on the description of the parts different from the first embodiment, and the description of the common parts may be omitted.
