Embodiment Construction

[0039]The following description is only for disclosing the present invention to enable those skilled in the art to practice the present invention. The embodiments in the following description are only examples, and those skilled in the art can think of other obvious modifications. The basic principles of the invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents and others without departing from the spirit and scope of the invention.

[0040] The invention provides a solar cell series welding system, which is used for welding and connecting multiple solar cells in series to form a solar cell string. In particular, the solar cell stringing system can realize stringing of solar cells by using flat ribbons and special-shaped ribbons, that is, it can realize the feeding of the special-shaped ribbons and the positioning and alignment of the solar cells. Specifically, the solar cell stringing system includes a speci...

Abstract

The invention provides a solar cell series welding system. The solar cell series welding system comprises a flat welding strip feeding device, a solar cell feeding device, a special-shaped welding strip feeding device, a welding platform and a heating device. The special-shaped welding strip feeding device comprises a first moving module and tongs installed on the first moving module. The tongs comprise grabbing pieces with first positioning grooves and first pressing pins. The welding platform comprises a body with second positioning grooves and first adsorption air holes. After special-shaped welding strips are put into the first positioning grooves of the tongs, the first pressing pins press the special-shaped welding strips, the first moving module drives the tongs to move and carry the special-shaped welding strips to the second positioning grooves of the body, and second adsorption air holes in the bottoms of the second positioning grooves adsorb the special-shaped welding strips. Solar cells are carried to the body and are adsorbed by the first adsorption air holes, and the special-shaped welding strips are aligned to interconnected electrodes on one faces of the solar cells. Flat welding strips are carried to the solar cells and are aligned to interconnected electrodes on the other faces of the solar cells.

Description

technical field [0001] The invention relates to the field of photovoltaics, in particular to a solar cell string welding system. Background technique [0002] The two sides of the solar cells are respectively symmetrically provided with several parallel silver interconnect electrodes (referred to as interconnect electrodes), and multiple solar cells can be connected by lapping the welding strips on the interconnect electrodes of two adjacent solar cells. connect them in series. Specifically, the solar cells and the ribbon are placed and positioned on the platform of the stringer, so that the solar cells and the ribbon are aligned, and then high-temperature heating and welding are performed to string the solar cells together. [0003] The traditional welding strips are mostly tinned copper flat strips (also known as flat welding strips). However, with the development of the industry, other shapes of ribbons have appeared, also called special-shaped ribbons. For example, tri...
