Abstract

The embodiment of the invention belongs to the technical field of solar cell manufacturing, and relates to a battery piece cutting device and a cutting method. The battery piece cutting device comprises a mounting base, a conveying device, a first laser emitting assembly, a second laser emitting assembly, a first moving device, a jig and a cooling assembly. The first laser emitting assembly, the second laser emitting assembly and the first moving device are all mounted on the mounting base; and the jig is driven to move through the conveying device. First laser emitted by the first laser emitting assembly is used for forming a cutting groove in a battery piece installed on the jig, and second laser emitted by the second laser emitting assembly is used for carrying out radiation heating on the cutting groove of the battery piece. The cooling assembly is slidably arranged on the first moving device; and the cooling assembly comprises a nozzle, and a cold source sprayed by the nozzle cools the cutting groove of the battery piece along with the second laser so that the battery piece can be broken along the cutting groove. According to the battery piece cutting device, the fragment rate of the battery piece in the cutting process can be reduced, the thermal damage area of the battery piece is reduced, and low-loss cutting is achieved.

Description

technical field [0001] The present invention relates to the technical field of solar cell manufacturing, and more specifically, to a cell slice cutting device and a cutting method. Background technique [0002] As we all know, a single solar cell cannot be used as a direct power supply, and multiple solar cells need to be spliced ​​together for packaging to form an assembly. This assembly is called a solar panel. Among them, the solar panel is an important part of the solar power generation system. [0003] In the prior art, the solar cells are mainly cut by scribing technology, that is, the single crystal or polycrystalline cells are cut into two halves or multiple parts by laser. However, the process of cutting cells by using the scribing technology first needs to ablate a cutting groove with a depth of 50-60um on the surface of the cells, and then use a mechanical breaking process to separate the cells. Obviously, this process route is easy to cause The expansion of the...
