Abstract

The invention relates to a method for mounting a cell string on the surface of a spatial solar cell substrate in the technical field of spatial solar power supply. The method adopts a mounting mechanism consisting of a negative pressure gripping and pressurizing frock and a frock clamp to realize the gripping of the cell string; screen printing technology is adopted to coat glue on the surface of the cell string; and after the mounting is completed, the cell string is pressurized through the negative pressure gripping and pressurizing frock to realize parallel operation of glue coating and pressurization of the cell string. The method can effectively solve the problems of glue spilling, denaturalization of the cell string and mounted bubbles in the process of mounting the cell string and realize automatic mounting.

Description

technical field

[0001] The invention relates to a method in the technical field of batteries, in particular to a method for mounting battery strings on the surface of a space solar battery substrate. Background technique

[0002] The space solar cell array is the main way for most spacecraft to obtain energy, and it is an important part of the spacecraft, and its processing quality directly affects the quality of the entire spacecraft. Automatic mounting of large-size ultra-thin flexible battery strings on the surface of space solar cell substrates is a very important process in the processing of space solar cell arrays. The labor intensity of workers is high and the working environment is poor. At present, the technical shortcomings of this process link are mainly reflected in the following aspects:

[0003] 1) The glue application method is backward, and the shape and thickness of the glue layer are difficult to control, resulting in either too much glue overflowing, or ...
