Method and equipment for producing solar battery string

Abstract

The invention discloses a method and equipment for producing a solar battery string. The method comprises the steps of S1, arranging m battery pieces along an X direction, wherein m is greater than or equal to 2; S2, respectively arranging the prepared m sets of welding strips extending along the Y direction above the m battery pieces, wherein the X direction intersects with the Y direction; S3, respectively arranging the m battery pieces above the m sets of welding strips to form m sets of unwelded battery strings, wherein the battery pieces in each set of battery strings are arranged in the Y direction, in two adjacent battery pieces in the same set of battery strings, each set of welding strips are respectively positioned above one battery piece and below the other battery piece; and S4, welding the welding strips in the m sets of battery strings with the battery pieces at the corresponding positions. The equipment comprises an arrangement station, a welding station, a welding strip preparation device, a battery piece supply device, a plurality of transmission devices and the like. According to the method, the production efficiency is greatly improved, the equipment is simple in structure and convenient to use and maintain, and the equipment cost and the occupied area are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of automatic manufacturing equipment, in particular to a method and equipment for producing solar battery strings. Background technique [0002] With the rise of energy prices, the development and utilization of new energy has become the main topic of research in the field of energy. Because solar energy has the advantages of no pollution, no regional restrictions, and inexhaustible supply, the study of solar power generation has become the main direction for the development and utilization of new energy. Using solar modules to generate electricity is a major way people use solar energy today, and solar cells are the main components of solar modules. [0003] In order to increase the output power of solar cells, connecting multiple cells in series is a common method. see Figure 22 and Figure 23 As shown, in the prior art, the method of connecting solar cells in series is as follows: the ribbon feeding m...

AI Technical Summary

Problems solved by technology

Therefore, the floor area and cost of the equipment are greatly increased, and it also brings great trouble to the use and maintenance of the equipment in the later stage, which in turn limits the improvement of production efficiency.

[0005] At present, there are some improved technologies for the production method of solar cell strings, such as optimizing the transmission mode of cells and conductor strips, which improves the production efficiency of cell strings, but essentially does not improve the equipment and does not solve the problem of high production costs. , The technical problem of the equipment occupying a large area

There are also some methods of producing solar cell strings that change the order in which cells and ribbons are alternately placed, and propose the idea of ​​producing small cells and welding, which effectively improves the production efficiency of small cells. In the process of welding a small battery string, it is necessary to lift the upper battery piece, which undoubtedly increases the complexity and difficulty of the production process, and correspondingly increases the production and operation costs of the equipment.

[0006] To sum up, most of the production methods of solar cell strings in the prior art have one or more problems such as low production efficiency, high production cost, large floor space, and difficult use and maintenance.
