A kind of processing method of photovoltaic module

Abstract

The invention discloses a processing method of a photovoltaic module, which belongs to the field of processing of photovoltaic modules. The method includes using a stringer to simultaneously weld at least two strings of batteries, and welding interconnection bars at predetermined positions; performing EL and appearance inspection / PL on cells in at least two strings of cells to obtain cell images and cell detection results; Automatically weld the bus bars at the head and tail of the battery string; place the cell modules in sequence on the front glass, and mark suspicious cells; if there are cells in the cell modules that need repairing, a repair instruction will be issued, and the The front plate glass with the battery module placed is transported to the rework station; the bus bars at the ends of the two adjacent battery modules are welded together at the stacking station; EL and appearance inspection / PL are carried out; the current photovoltaic module production is solved The problem of high labor costs in the process; it has achieved the effect of improving the production efficiency of photovoltaic modules and reducing labor costs.

Description

technical field [0001] Embodiments of the present invention relate to the field of photovoltaic module processing, in particular to a method for processing photovoltaic modules. 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, solar power generation has become the main direction for the development and utilization of new energy sources. Using solar cells to generate electricity is a major way for people to use solar energy today.

Problems solved by technology

[0003] The stringer of the conventional photovoltaic module stringer station can only string out one string of batteries, and the efficiency is relatively low. One production line needs to purchase multiple stringer machines to cooperate with the subsequent process equipment; and after stringing, an independent The typesetting process, the tape-attaching process for fixed strings, the welding bus bar and lead-out process, all these processes require additional equipment or manual actions, and also require a lot of space and capital resources to be occupied

In addition, the abnormalities in the serial welding process need manual online inspection, otherwise it is impossible to judge whether there are batches or serious defects in time, and the actual location of the defects is unknown. Low

Conventional photovoltaic modules are inspected for appearance and EL (Electro Luminescence, electroluminescence) after laying the back adhesive film and the rear sheet manually. If there is a problem of cracks during serial welding, it will be discovered later, and a large number of defective products will be produced. A lot of labor is wasted to repair, and there will also be material loss
