Automatic batch tracing method of solar cells

Abstract

The invention discloses an automatic batch tracing method of solar cells. The automatic batch tracing method comprises the steps: screen-printing electrodes on a battery substrate through a screen printer and sintering to obtain the solar cells; carrying out efficiency detection on the solar cells by a sorting machine and packing the finished solar cells, arranging a baffle piece between the two adjacent solar cells in different batches, arranging an automatic optical detection lens on the sorting machine, connecting the automatic optical detection lens with the sorting machine and the screen printer, automatically switching the batches of the cells when the automatic optical detection lens senses the baffle pieces; carrying out system integration to enable information of switching the batches to be linked with a finished product package number automatically, storing the batches and the manufacturing time which are included in each finished product package in a system; automatically finding relative batch numbers automatically and relevant manufacturing information by only inputting the finished product package number in the system when reverse tracing is needed. By using the automatic batch tracing method, the batches of the solar cells can be automatically switched, the labor cost of manufacture stations is reduced, and the product tracing yield can be up to 100 percent.

Description

technical field [0001] The patent of the invention relates to an automatic batch tracking method for solar cells, which belongs to the technical field of solar cells. Background technique [0002] At present, the solar battery batch tracking methods on the assembly line are: 1. Running a single barcode with a barcode reader; 2. The electronic label on the flower basket is equipped with an electronic label reader. The above two methods will have mixed batch problems at the final site where screen printing is combined with automatic sorting. Such as figure 1 As shown, in order to match fast mass production, screen printing, electrode sintering and efficiency grading are matched in a streamlined manner, so cells of different batches will be combined into the same efficiency grade for shipment, resulting in difficulty after shipment. Track the batch of origin of finished goods. [0003] There are two traditional solutions: 1. Advanced flower baskets after sintering, and then ...

2. Using intervals or block partitions in the batch, inputting the batch change signal at the grading station manually needs to increase the labor cost of production, and at the same time, human factors lead to an increase in the risk of mixed batches
