Battery interconnection method and system and solar battery interconnection equipment

Abstract

The invention provides a battery interconnection method, a battery interconnection system and solar battery interconnection equipment. The method comprises the following steps: establishing a currentcoordinate system for a battery which is currently loaded to a dispensing slide holder, and determining the position of the current battery in the current coordinate system; when the next battery is loaded to the dispensing slide holder, adjusting the current coordinate system into a second coordinate system according to the position deviation of the next battery relative to the current battery; and adjusting a glue dispensing head to dispense a glue on the next battery according to the deviation between the position of the next battery in the second coordinate system and the position of the current battery in the current coordinate system so as to realize interconnection between the current battery and the next battery. According to the battery interconnection method, the glue dispensingtime of battery interconnection can be greatly shortened, the glue dispensing rate is increased, the glue dispensing accuracy can be greatly improved, and the battery interconnection yield is improved.

Description

technical field [0001] The present invention relates to the technical field of solar cells, in particular to a battery interconnection method, system and solar cell interconnection equipment. Background technique [0002] In the field of solar cell preparation, a solar cell interconnection process is usually required. The solar cell interconnection process is a process of connecting multiple solar cells in series or in parallel to form a large cell. Each solar cell has a front electrode and a back electrode. In series, the front electrode of one cell is interconnected with the back electrode of another cell; in parallel, the front electrodes of multiple cells are interconnected, and the back electrodes are interconnected. [0003] At present, in the battery series process, the batteries are usually loaded onto the dispensing stage one by one, and their positions on the stage are adjusted one by one, so that the dispensing positions of the two interconnected batteries are as...

AI Technical Summary

Problems solved by technology

This interconnected dispensing process requires the dispensing head to start from the origin of the original coordinate system and move to the dispensing position of the battery every time, which makes the speed of battery interconnection slower, and the positioning of the battery during the interconnection process is not accurate enough. As a result, the battery interconnection rate and interconnection yield are low
