Description

The present invention relates to a work holding jig used for electroless plating, a work attaching method to the work holding jig, and the like.

Unlike electroplating, electroless plating has the advantage that the workpiece to be plated is not only a conductor but also a non-conductor such as plastic or ceramics because no current flows in the bath.

According to Patent Document 1, a plurality of wiring boards are arranged vertically in a plating tank containing an electroless plating solution through a gap through which an electroless plating solution can flow, or hung from a rack and batched. It is disclosed to process (claims 1 and 3 and FIG. 4).

Japanese Unexamined Patent Publication No. 2006-93651

In recent years, with the miniaturization of electronic devices such as smartphones, wiring boards have become thinner. When the thickness of the wiring board is, for example, 100 μm or less, the wiring boards arranged upright on the rack or suspended from the rack as in Patent Document 1 are bent due to the thinness.

An object of the present invention is to prevent bending of a plurality of workpieces to be batch-processed, to secure a gap between the workpieces through which an electroless plating solution can flow, and to hold a workpiece capable of electroless plating while maintaining plating quality. It is an object of the present invention to provide a method of attaching a work to a jig and a work holding jig.

Hereinafter, preferred embodiments of the present invention will be described in detail. It should be noted that the present embodiment described below does not unreasonably limit the content of the present invention described in the claims, and all of the configurations described in the present embodiment are essential as a means for solving the present invention. Is not always.

1. 1. Work holding jig FIG. 1 is a perspective view of a work holding jig according to an embodiment of the present invention. In FIGS. 1 to 4, the work holding jig 10 has a jig main body 20. The jig main body 20 includes a quadrangular upper frame 30, a quadrangular lower frame 40, and a connecting portion 50 for connecting the upper frame 30 and the lower frame 40. The direction in which each work W (see FIGS. 2 and 3) is carried into the jig main body 20 is defined as the first direction A. The step movement direction of the work holding jig 10 after the one work W is carried in is defined as the second direction B.

The upper frame 30 connects the first and second upper frame members 31 and 32 facing each other in the first direction A and the third and fourth upper frame members 33 and 34 facing each other in the second direction B in a square frame shape. It is composed of. The first and second upper frame members 31 and 32 facing each other in the first direction A are provided with, for example, a plurality of slits 31A and 32A having openings at the lower ends. Further, the first and second upper frame members 31 and 32 are integrated with hooks 31B and 32B supported by an elevating member 200 (see FIG. 3) that suspends the work holding jig 10 and elevates it to and from the plating bath. It is formed. The upper frame members 33 and 34 of the jig body 20 are reinforcing members for forming the upper frame 30. The portion of the upper frame 30 does not necessarily have to be frame-shaped, and may have at least the upper frame members (a pair of upper horizontal members) 31 and 32 parallel to each other in which the slits 31A and 32A are formed.

The lower frame 40 connects the first and second lower frame members 41 and 42 facing each other in the first direction A and the third and fourth lower frame members 43 and 44 facing each other in the second direction B in a square frame shape. It is composed of. The first and second lower frame members 41 and 42 facing each other in the first direction A are provided with a plurality of, for example, 20 slits 41A and 42A having openings at the upper ends facing the upper slits 31A and 32A. If necessary, as shown in FIG. 1, at a position where the distance between the first and second lower frame members 41 and 42 is divided into two, both ends are fixed to the third and fourth lower frame members 43 and 44. The material 45 may be provided. The intermediate member 45 is also provided with a slit 45A that opens at the upper end at a position facing the slits 41A and 42A in the first direction A. The lower frame members 43 and 44 of the jig body 20 are reinforcing members for forming the lower frame 40. The portion of the lower frame 40 does not necessarily have to be frame-shaped, and may have at least the upper frame members (a pair of lower horizontal members) 41 and 42 parallel to each other in which the slits 41A and 42A are formed.

The connecting portion 50 that connects the upper frame 30 and the lower frame 40 has a plurality of, for example, four vertical frame members 51 to 54 that vertically connect the four corners of the upper frame 30 and the lower frame 40. The connecting portion 50 may have a reinforcing member if necessary, and has a horizontal reinforcing member 55 and a vertical reinforcing member 56 that reinforce two surfaces facing each other in the second direction B in FIG. The reinforcing member may be a brace.

In the connecting portion 50, for example, in FIG. 1, no reinforcing member that crosses or traverses each surface is arranged on the two surfaces facing each other in the first direction A. As a result, in the present embodiment, the space surrounded by the first upper frame member 31, the first lower frame member 41, and the two vertical frame members 51 and 52 connecting them is the carry-in entrance 60 of the work W. Is secured as. The carry-in entrance 60 can also be used as a carry-out outlet. Since no reinforcing member is arranged in the space surrounded by the second upper frame member 32, the second lower frame member 42, and the two vertical frame members 53 and 54 connecting them, the work W is carried into this space. It can be used as a carry-in / exit port for a jig that holds the carry-in tip or the carry-out rear end of the work W when it is taken out.

Both ends of a plurality (20 pieces) of the first support plates (first support members) 70 are inserted into the slits 31A and 32A of the first and second upper frame members 31 and 32 of the upper frame 30, and the first and first supports are inserted. 2 The upper frame members 31 and 32 are supported (for example, fixed) so as not to fall. As a result, the plurality of first support plates 70 are supported in parallel between the two opposite sides of the upper frame 30 in the first direction A. Each of the plurality of first support plates 70 is supported by a plurality of, for example, four first clamp members 80 that clamp the upper ends of each of the plurality of rectangular workpieces W by an urging force. In the slits 31A, 32A of the first and second upper frame members 31, 32, both ends of a plurality (20 pieces) of the first support plates 70 may be supported so as to be able to move up and down. In this case, the plurality of first support plates 70 may be moved and urged upward with respect to the upper frame 30 by an urging force such as a spring.

Both ends of a plurality (20 pieces) of the second support plates (second support members) 90 are inserted into the slits 41A and 42A of the first and second lower frame members 41 and 42 of the lower frame 40 to be supported. Both ends of the plurality of second support plates 90 are prevented from coming off by the regulating members 46 attached so as to cover the slits 41A and 42A of the lower frame members 41 and 42 shown in FIG. As a result, the plurality of second support plates 90 are supported in parallel between the two opposite sides of the lower frame 40 in the first direction A. Unlike the first support plate 70, the second support plate 90 is not fixed to the slits 41A and 42A, and can be moved up and down by being guided by the slits 41A and 42A. Further, the bottom surfaces of the slits 41A and 42A in the depth direction set the lower limit position of the second support plate 90. Each of the plurality of second support plates 90 is supported by a plurality of, for example, four second clamp members 100 that clamp the lower end portions of each of the plurality of work Ws by an urging force. When the plurality of first support plates 70 are supported so as to be able to move up and down, the plurality of second support plates 90 may be fixed.

Here, according to the present embodiment, at the lower end of each of the plurality of workpieces W suspended by the plurality of first clamp members 80, each of the plurality of second support plates 90 and the plurality of second clamp members 100 are attached. Can act on its own weight. This is because each of the plurality of second support plates 90 holding the plurality of second clamp members 100 can be raised and lowered by the slits 41A and 42A provided in the lower frame 40, and is lowered by their own weight to lower the work W. This is because it gives tension to. Each of the plurality of second support plates 90 in the lowered position is designed so as not to come into contact with the bottom surfaces of the slits 41A and 42A in the depth direction. As a result, the plurality of works W can be arranged in parallel without bending. As a result, when a plurality of work Ws held by the work holding jig 10 are immersed in the plating bath, even if the work W is thin, there is an appropriate gap through which the electroless plating solution can flow between the adjacent work Ws. It will be secured. As a result, a plurality of work Ws can be batch-processed by electroless plating while maintaining the plating quality.

The clamp structure of the upper end portion of the work W is shown in FIGS. 5 (A) to 5 (C). In FIGS. 5 (A) to 5 (C), the first holder 71 is fixed to each of the plurality of first support plates 70. The first holder 71 supports the shaft 72. The first clamp member (movable piece) 80 is swingably supported on the shaft 72. The first clamp member 80 is subjected to the first urging force by the torsion coil spring 73 inserted through the shaft 72. The first clamp member 80 has a clamp end 82 at one end and a lever 83 at the other end. The first holder 71 includes a first vertical surface 74. The first vertical surface 74 is provided so as to locally extend downward from the first holder 71 in a region facing the clamp end 82 of the first clamp member 80 swingably supported by the first holder 71. Can be done. The first clamp member 80 is brought into contact with and separated from the first vertical surface 74. That is, the upper end portion of the work W is clamped between the clamp end 82 of the first clamp member 80 and the first vertical surface 74, and the clamped state is maintained by the first urging force of the torsion coil spring 73. By applying the first external force F1 to the lever 83 against the first urging force of the coil spring 73, the clamp end 82 of the first clamp member 80 moves in the direction away from the first vertical surface 74, and the work W The clamped state of is released.

In this way, one of the pair of members sandwiching the upper end portion of the work W is a first vertical surface 74 provided on the first holder 71 that swingably supports the plurality of first clamp members 80. The score decreases. Further, the vertical posture of the work W can be ensured following the first vertical surfaces 74 formed in the regions facing the plurality of first clamp members 80. The first vertical surface 74 may be provided on the first support plate 70 instead of the first holder 71, and the same action / effect can be obtained even in this case.

The clamp structure at the lower end of the work W is shown in FIGS. 6 (A) to 6 (C). In FIGS. 6A to 6C, a second holder 91 is fixed to each of the plurality of second support plates 90. The second holder 91 supports the shaft 92. The second clamp member (movable piece) 100 is swingably supported on the shaft 92. A second urging force is applied to the second clamp member 100 by a torsion coil spring 93 inserted through the shaft 92. The second clamp member 100 has a clamp end 102 at one end and a lever 103 at the other end. The second holder 91 includes a second vertical plane 94. The second vertical surface 94 can be provided locally extending upward from the second holder 91 in a region facing the four second clamp members 100 oscillatingly supported by the second holder 91. The second clamp member 100 is brought into contact with and separated from the second vertical surface 94. That is, the lower end portion of the work W is clamped between the clamp end 102 of the second clamp member 100 and the second vertical surface 94, and the clamped state is maintained by the second urging force of the torsion coil spring 104. By applying a third external force F3 to the lever 103 against the second urging force of the coil spring 93, the clamp end 102 of the second clamp member 100 moves in a direction away from the second vertical surface 94, and the work W The clamped state of is released.

As described above, one of the pair of members sandwiching the lower end portion of the work W is a second vertical surface 94 provided on the second holder 91 that swingably supports the plurality of second clamp members 100. The score decreases. Further, the vertical posture of the work W can be ensured following the second vertical surfaces 94 formed in the regions facing the plurality of second clamp members 100. In particular, the upper end of the work W follows the first vertical surface 74, and the lower end of the work W follows the second vertical surface 94, so that the vertical posture of the work W can be more reliably secured. As a result, an appropriate gap through which the electroless plating solution can flow is surely secured between the works W. The second vertical surface 94 may be provided on the second support plate 90 instead of the second holder 91, and the same action / effect can be obtained even in this case.

2. 2. Method of Attaching Work to Work Holding Jig A method of attaching the work W to the work holding jig 10 of the present embodiment will be described with reference to FIGS. 1 and 5 to 9.
2.1. First step In step 1 shown in FIG. 9, the first clamp member 80 is opened. Specifically, one of the plurality of first support plates 70, for example, a plurality of first clamp members 80 held by one first support plate 70 adjacent to the fourth upper frame member 34 of the upper frame 30 in FIG. Is applied with a first external force F1 (see FIG. 5B) that opposes the first urging force of the torsion coil spring 73 so that it can be clamped.

2.2. Second step In step 2 shown in FIG. 9, the second clamp member 100 is opened at a position where the work W can be received. Specifically, one of the plurality of second support plates 90, for example, one second support plate 90 adjacent to the fourth lower frame member 44 of the lower frame 40 in FIG. 1, is a second external force F2 shown in FIG. Is given to raise the lower frame 40 from the lower limit position in the slits 41A and 42. Further, a plurality of second clamp members 100 held by the one second support plate 90 are subjected to a third external force F3 (see FIG. 6B) that opposes the second urging force of the torsion coil spring 93. Give it to make it clampable. The external forces F2 and F3 may be applied at the same time or either one may come first. Further, the first step and the second step may be performed at the same time, or either one may be the first.

2.3. Third step In step 3 shown in FIG. 9, one piece of work W is placed in a vertical state, horizontally moved in the first direction A shown in FIG. 1, and carried into the jig main body 20 from the carry-in entrance 60. At this time, the work W can carry the work W into the jig main body 20 without interfering with the work holding jig 10 by grasping, for example, the transport front end portion and the transport rear end portion, respectively. As a result, the upper end portion of the work W is arranged between the first vertical surface 74 of one first support plate 70 and the plurality of first clamp members 80 supported by the first vertical surface 74. Further, the lower end portion of the work W is arranged between the second vertical surface 94 of one second support plate 90 and the plurality of second clamp members 100 supported by the second vertical surface 94.

2.4. Fourth Step In step 4 shown in FIG. 9, the first external force F1 shown in FIG. 5 and the third external force F3 shown in FIG. 6 are released to release the plurality of first clamp members 80 and the plurality of second clamp members 100. It is used to clamp the upper end and the lower end of one work W. The state after the completion of the fourth step is shown in FIG. At this time, the distance between the upper and lower ends of the work W is L1.

2.5. Fifth Step In step 5 shown in FIG. 9, one of the plurality of second support plates 90 is lowered by releasing the second external force F2 as shown in FIG. At this time, the distance between the upper and lower ends of the work W is a distance L2 longer than the distance L1 shown in FIG. Therefore, tension is applied to one work W. The work W is flexed by applying tension. As a result, the attachment of one work W to the work holding jig 10 is completed. At this time, for example, a counter (not shown) is counted up, and the initial value N = 0 is changed to N = 1.

In step 6 shown in FIG. 9, it is determined whether all the workpieces W have been attached to the workpiece holding jig 10. In the present embodiment, when N = 20, the determination in step 6 becomes YES, and the attachment of the work W to the work holding jig 10 is completed. If N <20, the determination in step 6 in FIG. 9 is NO, and the first to fifth steps (steps 1 to 5) are repeated until all the work W is attached to the work holding jig 10. Will be done. As described above, according to the present embodiment, the first to third external forces F1 to F3 are applied / released to the work holding jig 10 (first, second, fourth, and fifth steps), and the first direction A of the work W is A. By the horizontal movement to the work holding jig 10 (third step), a plurality of works can be attached to the work holding jig 10, and the attachment of the work W to the work holding jig 10 can be easily automated.

2.6. 6th Step In the present embodiment, if the determination in step 6 shown in FIG. 9 is NO, as shown in step 7 of FIG. 9, in preparation for carrying in the next work W to be attached to the work holding jig 10. Further, there can be a sixth step of horizontally moving the work holding jig 10 in the second direction B orthogonal to the first direction A shown in FIG. Then, in automating the above method, a device for applying / releasing the first to third external forces F1 to F3 and a device for carrying in the work W are obtained by simply moving the work holding jig 10 horizontally in the second direction B. It is possible to complete the attachment of all the workpieces W to the workpiece holding jig 10 without requiring movement. Therefore, the structure of the work mounting device is simplified.

Although the present embodiment has been described in detail as described above, those skilled in the art will easily understand that many modifications that do not substantially deviate from the novel matters and effects of the present invention are possible. Therefore, all such modifications are included in the scope of the present invention. For example, a term described at least once in a specification or drawing with a different term in a broader or synonymous manner may be replaced by that different term anywhere in the specification or drawing. Further, all combinations of the present embodiment and modifications are also included in the scope of the present invention.

For example, in the mounting method described above, the work Ws are mounted one by one on the work holding jig 10, but a plurality of work Ws are simultaneously carried into the jig body 20 and the plurality of work Ws are mounted at the same time. Is also good.

In the above-described embodiment, the lower second support plate 90 and the second clamp member 100 are lowered by their own weight to apply tension to the work W, but the present invention is not limited thereto. The upper first support plate 70 and the first clamp member 80 may be raised with respect to the upper frame 30 by an urging force such as a spring to apply tension to the work W. In that case, the second external force F2 shown in FIG. 7 is a downward external force acting on the first support plate 70.

Further, the tension given to the work W does not have to be given when the work W is attached to the work holding jig 10, and may be given at least when the work holding jig 10 is arranged in the processing tank. Therefore, when the first support plate 70 is made movable with respect to the upper frame 30, the first support plate 70 does not necessarily have to be urged upward with respect to the upper frame 30 by a urging force such as a spring.

Further, the work holding jig 10 may be formed so that the work W having a different vertical size can be held. For this reason, the vertical frame members 51 to 54 of the connecting portion 50 can be adjusted in length in the vertical direction by a known slide mechanism and lock mechanism. As a result, the vertical distance between the pair of upper horizontal members 31 and 32 and the pair of lower horizontal members 41 and 42 can be made variable. Work Ws having different horizontal sizes may be formed on the work holding jig 10 so as to be able to hold them. In this case, if the size of the work holding jig 10 is manufactured according to the maximum horizontal size work W, it is possible to hold a work W having a horizontal size smaller than that.
