Summary of invention

Here, consideration is given to the case where wiring is performed with a predetermined wiring material different from a general wiring material. First of all, the term "general wiring material" refers to a person who applies a flat copper wire to a full-coating of solder or lead-free solder.

On the other hand, as a subsequent object, the predetermined wiring material different from the general wiring material also refers to a person who applies a flat copper wire to a full-coating of solder or lead-free solder, but as shown in Fig. 16(a) As shown in the cross-sectional view, in combination with the necessary length (L) for connecting the inner surface side and the surface side of the two solar battery cells, the concave and convex portions of the reflected light and the non-concave portions are alternately formed on the surface in a predetermined pattern. Only the welded part of the solder layer. The length of the pattern is as shown in the 16th (b) diagram described later, and is assumed to be the structure of the manufactured string. In the setter, the reflection characteristics of the light of the uneven portion and the non-concave-welded portion are different. In the predetermined wiring material, the photoelectric conversion efficiency of the solar cell module is improved by diffusing and reflecting sunlight on the uneven portion formed on the surface, for example, the wiring material described in FIG. 14 of Patent Document 1.

However, when wiring is performed using a predetermined wiring material as described above, it is necessary to discard an unnecessary portion of the wiring material unlike a general wiring material. Next, the disposal of the unnecessary portion of the wiring member will be described.

The length of the wiring material differs depending on which position is placed on the string. As shown in Fig. 16(b), the wiring material placed on the string is the wiring of the wiring member 301 at the head before the string, the wiring member 307 at the end of the string, and the wiring of the other portion (the middle portion of the string). The materials 302 to 306 are formed, and the lengths of the front head wiring member 301, the end portion wiring member 307, and the intermediate portion wiring members 302 to 306 are set to arbitrary values, and the lengths of the intermediate portion wiring members 302 to 306 are all equal.

The predetermined wiring material is manufactured in advance so that the length of L shown in Fig. 16(a) matches the length of the intermediate portion wiring member.

Since the general wiring material is formed into a uniform structure as a whole, the cutting is not restricted by the structure at any position, and it is only necessary to set the required length and cut it. However, when a predetermined wiring material is used, since the uneven portion is required to face in the same direction as the light receiving surface of the unit, it is necessary to cut the position of the uneven portion and then cut it.

For example, when a string of wires is continuously formed in a normal manner, the front head wiring member can be cut => the intermediate portion wiring member is cut a plurality of times => the end portion of the wiring member is cut and repeated, and only the necessary length of each portion is set. Yes, but make When the predetermined wiring material is used, it is necessary to cut the front head wiring material => the intermediate portion wiring material is cut a plurality of times => the end portion of the wiring material is cut and the unnecessary portion is discarded.

In the case where the wiring member 307 at the end of one string is cut, and then the wiring member 301a of the head before the string is cut, the unnecessary portion is as shown in Fig. 16(c). The unnecessary portion R is generated when the length of the wiring member 307 at the end portion and the wiring member 301a of the front portion are different from L.

Further, in the predetermined wiring member, there is an error in the accuracy of the formation of the pattern caused by the presence or absence of the unevenness. Therefore, even if the wiring member is correctly cut according to the predetermined length, the cutting position may be deviated from the assumed position in the repeated plurality of cuttings. Alternatively, when a plurality of wiring materials are used, even if the first cutting is aligned with each other, there is a possibility that the cutting position of each of the wiring materials becomes different in the repeated cutting.

As a result, the accuracy of the wiring is affected, and as a result, the performance of the solar cell module is lowered, and it is necessary to correct it. Therefore, the alignment is effective every time the unnecessary portion of the wiring member generated by the string is discarded. In addition, it is necessary to perform alignment when manually installing the wiring material during the exchange of the bobbin. That is, it is effective to fix the unnecessary portion of the discarding process before cutting the front head.

In the conventional wiring device, the wiring material can be cut to a set length. In this process, the end portion of the wiring member wound around the bobbin or the like is sandwiched between the head portion and the like, and the necessary length of the chuck member is moved by the servo or the like to be cut and cut.

However, in the conventional wiring device, it cannot be based on the wiring material. The shape automatically cuts the unneeded parts.

In view of the above, the present invention provides a wiring device and a wiring method for a solar battery cell that can automatically cut an unnecessary portion based on the shape of a wiring member.
