[0010] Hereinafter, an embodiment of the present invention (hereinafter, referred to as "the present embodiment") will be described in detail with reference to the drawings. Note that each drawing is merely a schematic illustration to allow a sufficient understanding of the present embodiment. In addition, in each drawing, common or similar components are given the same reference numerals, and duplicated explanations thereof will be omitted.

[0011] (Embodiment) Fig. 1 is an external view of a connecting jig according to an embodiment of the present invention. The X, Y, and Z directions are as indicated by the arrows. In Fig. 1, the vertical direction is the Z direction. The connecting jig 100 is a fabrication jig for fabricating a connected flexible substrate 10 (FIG. 2) by connecting the tip portions 11a, 12a (FIG. 2) of two flexible substrates 11, 12 (FIG. 2) with a head 13 (FIG. 2). The head 13 functions as a connecting member that connects the two flexible substrates 11, 12. The head 13 also functions as a connecting member that is connected to a connector (not shown). The connecting jig 100 (FIG. 1) is configured to include a main body 50 and a plate 20. The main body 50 includes a holding mechanism 40, a mounting plate 51, a slide mechanism 52, and an XY stage 60. The plate 20 is for mounting one of the flexible substrates 11, 12 (FIG. 2), and is configured to be removable from the mounting plate 51 using two handles 25 (see FIG. 8).

[0012] The holding mechanism 40 holds the head 13 (FIG. 2) and includes locking plates 41, 42 and a head mounting base 43. The head 13 (FIG. 2) is fixed to the upper surface of the head mounting base 43. The head 13 is joined to the flexible substrates 11, 12 (FIG. 2) or their electrodes (not shown) on the upper surface of the head mounting base 43. Here, the surfaces where the flexible substrates 11, 12 or their electrodes are joined to the head 13 are referred to as the joining surfaces. The locking plates 41, 42 are fixed to the head mounting base 43, and both ends of the head 13 (FIG. 2) are fixed by abutment surfaces 41c, 42c (FIG. 7).

[0013] The slide mechanism 52 is composed of a moving part 52a and a fixed part 52b, and slides the holding mechanism 40 in the X direction. That is, the holding mechanism 40 is capable of sliding along one side of the mounting plate 51. The XY stage 60 moves the mounting plate 51 in at least one of the X direction and the Y direction.

[0014] Fig. 2 is an outline view of the connected flexible substrate 10. Fig. 2(a) is a left side view, Fig. 2(b) is a front view, and Fig. 2(c) is a right side view. The connected flexible substrate 10 is formed by connecting the tip portions 11a, 12a of two flexible substrates 11, 12 with a head 13. The flexible substrates 11, 12 are formed with different patterns, but are almost plane symmetric. Therefore, the two flexible substrates 11, 12 face each other in the connected flexible substrate 10. The flexible substrates 11, 12 are formed with long portions 11c, 12c. For example, the head 13 is attached to the tip portions of the long portions 11c, 12c so that the head 13 as a connector can be easily connected to another connector (not shown). In addition, the flexible substrates 11, 12 are formed with component mounting portions 11d, 12d, and the long portions 11c, 12c and the component mounting portions 11d, 12d are collectively referred to as main portions 11b, 12b.

[0015] Fig. 3 is a configuration diagram of the plate 20 that constitutes the connecting jig 100. Fig. 3(a) is a plan view thereof, and Fig. 3(b) is a right side view thereof. The plate 20 has a rectangular shape in a plan view. The plate 20 is formed by stacking two plate materials 20a, 20b. A plurality of suction holes 21 are formed in the plate 20. When air is sucked from the suction holes 21 with one of the flexible boards 11, 12 placed on the upper surface of the plate 20, one of the flexible boards 11, 12 is adsorbed to the plate 20. Therefore, air flow holes 22 are formed two-dimensionally on the contact surfaces of the two plate materials 20a, 20b. In addition, two handles 25 are attached to the plate 20. The handles 25 facilitate removal from the mounting plate 51 (FIG. 1) (see FIG. 8).

[0016] (Method of manufacturing linked flexible substrates) Fig. 4 is a perspective view for explaining a first step (SP1) of the manufacturing method of the linked flexible substrate according to the embodiment of the present invention. Fig. 5 is an enlarged view of the periphery of the holding mechanism 40. Fig. 6 is a cross-sectional view taken along line AA in Fig. 5. In Fig. 6, the head mounting table 43 is depicted as being composed of a base body 43a and an adjustment member 43b. Fig. 7 is a plan view of the periphery of the holding mechanism 40.

[0017] (Step SP1) 4 to 7, a first step (SP1) of the method for manufacturing a connected flexible substrate in which flexible substrates 11, 12 are connected via head 13 will be described below. Note that the connecting jig 100 in Fig. 4 is in a state in which plate 20 is attached onto mounting plate 51. Also, air is constantly being sucked in through a plurality of suction holes 21.

[0018] In step SP1, the worker connects the flexible substrate 11 as the first flexible substrate to the head 13 (FIGS. 5 and 6) (SP1). That is, the worker places the plate 20 on the mounting plate 51 (second plate mounting process), and places the head 13 on the end of the head mounting base 43 so as to abut against the abutment plate 45 (FIGS. 5 and 6). Then, the worker slides the locking plates 41 and 42 in the X direction along the long holes 41a and 42a (FIGS. 5 and 7) while loosening the screws (not shown) screwed into the screw holes 44 (FIG. 7), thereby sandwiching the head 13 between the abutment surfaces 41c and 42c. The side surfaces of the locking plates 41 and 42 on the plate 20 side are positioned by abutting against the abutment plate 45 (FIG. 5).

[0019] Furthermore, the worker places a part (main part 11b) of the flexible substrate 11 on the upper surface of the plate 20 (third substrate placing step), and places the tip part 11a (FIG. 2) of the long part 11c on the head 13. This causes the flexible substrate 11 to be adsorbed to the plate 20. Thereafter, the worker electrically joins the flexible substrate 11 to the head 13 (FIG. 5) (second joining step). This electrical connection is achieved by pressure welding, metal paste, a wire harness, or the like.

[0020] (Step SP2) FIG. 8 is a perspective view for explaining the second step (SP2) of the method for producing linked flexible substrates according to the embodiment of the present invention. In step SP2, the flexible substrate 11 to which the head 13 is attached is removed from the plate 20, and the plate 20 is then removed from the mounting plate 51 (removal process). This exposes the recess 51b formed in the mounting plate 51. Then, the holding mechanism 40 is slid in the direction of the arrow (-X direction).

[0021] (Step SP3) FIG. 9 is a perspective view for explaining the third step (SP3) of the method for producing linked flexible substrates according to the embodiment of the present invention. In step SP3, the worker turns over the flexible substrate 11 to which the head 13 is connected in step SP1 and places it on the recess 51b of the mounting plate 51 (first substrate mounting step), and clamps the head 13 between the locking plates 41 and 42. As a result, the head 13 is fixed to the end of the head mounting base 43.

[0022] (Step SP3) FIG. 10 is a perspective view illustrating a fourth step (SP4) in the method for producing linked flexible substrates according to the embodiment of the present invention. In step SP4, the worker first attaches the plate 20 to the mounting plate 51 (first plate mounting step). When the plate 20 is attached to the mounting plate 51, a part (main part 11b) of the flexible substrate 11 is accommodated in a space formed between the lower surface of the plate 20 and the upper surface (bottom surface of the recess 51b) of the mounting plate 51. Next, the worker places the flexible substrate 12 as a second flexible substrate on the plate 20 (second substrate mounting step). At this time, the tip of the flexible substrate 12 is joined on the head 13 fixed on the upper surface of the head mounting base 43 (first joining step). Depending on the shape of the flexible substrates 11 and 12, there may be cases where the suction holes 21 (FIGS. 3 and 8) are not blocked. The suction holes 21 that are not blocked by the flexible substrates 11 and 12 are blocked by the sealing plate 29. The sealing plate 29 prevents air leakage.

[0023] FIG. 11 is a cross-sectional view taken along line BB of FIG. When the plate 20 is attached to the mounting plate 51, the flexible substrate 11 is inclined in the vicinity of the head mounting base 43. That is, the flexible substrate 11 is inclined due to the difference in height between the joint surface between the head 13 and the flexible substrate 11 and the recess 51b. However, an inclined surface 23 is formed on the edge of the plate 20 on the head mounting base 43 side, which is inclined so as to move away from the head mounting base 43 as it goes downward. In other words, the distance between the lower surface side of the plate 20 and the head mounting base 43 of the inclined surface 23 is longer than the distance between the upper surface side of the plate 20 and the head mounting base 43. Therefore, the inclination of the end of the flexible substrate 11 becomes gentler, and the flexible substrate 11 is less bent. The height of the joint surface between the head 13 and the flexible substrate 12 and the upper surface of the plate 20 are approximately the same.

[0024] As described above, according to the connecting jig of this embodiment, when manufacturing a connected flexible substrate 10 including flexible substrates 11 and 12, one flexible substrate 11 to which head 13 is attached can be placed in the recess 51b in an inverted state. Furthermore, by attaching plate 20 to mounting plate 51, plate 20 is placed on one flexible substrate 11 placed in recess 51b. The other flexible substrate 12 is placed on the upper surface of plate 20, and tip portion 12a of flexible substrate 12 is joined to head 13. In this manner, connected flexible substrate 10 is manufactured. Furthermore, since inclined surface 23 is formed on plate 20, bending of flexible substrate 11 is reduced.

[0025] (Modification) The present invention is not limited to the above-described embodiment, and various modifications are possible, for example, as follows. (1) In the connecting jig 100 of the above embodiment, a slide mechanism 52 is provided and the worker slides the holding mechanism 40 in the -X direction (FIG. 8, step SP2). However, if the holding mechanism 40 is provided in the center of the mounting plate 51 and the plate 20 in the X direction, there is no need to provide the slide mechanism 52.

[0026] (2) In the connecting jig 100 of the above embodiment, the recess 51b is formed in the mounting plate 51 to provide a space capable of accommodating the flexible substrate 11, but a recess may be formed in the lower surface of the plate 20. Also, recesses may be formed in both the mounting plate 51 and the plate 20. In other words, a space capable of accommodating the flexible substrate 11 may be provided on the opposing surfaces of the mounting plate 51 and the plate 20.

[0027] (3) In the method for manufacturing linked flexible substrates of the above embodiment, flexible substrate 11 is placed on plate 20 and an end of flexible substrate 11 is connected to head 13 (SP1), but if the end of flexible substrate 11 is to be connected to head 13, there is no need to use linking jig 100. That is, the worker only needs to carry out the steps of placing flexible substrate 11 with head 13 connected in recess 51b of mounting plate 51 (SP2), attaching plate 20 to mounting plate 51 with flexible substrate 11 inserted between the opposing surfaces of mounting plate 51 and plate 20, and placing flexible substrate 12 on plate 20 and connecting the end of flexible substrate 12 to head 13 (SP4).

[0028] (4) In the above embodiment, the upper surface of plate 20 is a flat surface, but a recess may be formed on which flexible substrates 11 and 12 can be placed. In this case, it is preferable that the height of the joining surface that joins head 13 and flexible substrates 11 and 12 is approximately the same as the height of the bottom surface of the recess.
