Description

Technical Field

[0001] The present invention relates to the technical field of series machines. Specifically, it particularly relates to a glue application device and a series machine with high precision for BC solar cells. Background Art

[0002] As an essential device for the production of photovoltaic cell strings, the main function of the series machine is to connect multiple solar cells in series through soldering tapes to form a cell string. During the production process of the series machine, first, a glue application operation needs to be performed on the solar cells. Then, the soldering tape is pulled out and straightened from the soldering tape reel by the soldering tape traction mechanism, and then the soldering tape is cut to a fixed length according to the required length. The cut soldering tape is laid flat on the grid line position of adjacent solar cells, and then the solar cells with the soldering tape placed are conveyed to the lower part of the UV curing device for the series connection of the cell string.

[0003] In the existing series machines, the glue application device places the solar cells under the glue application mesh plate through the lifting and supporting handling mechanism, and then the scraper mechanism presses down to scrape the glue or solder paste on the glue application mesh plate, so that the glue or solder paste adheres to the solar cells, thereby realizing the glue application operation. Due to the high viscosity of the glue or solder paste, there is no real-time position information correspondence between the solar cells on the existing glue application device and the mesh plate, and glue application printing deviation often occurs, which cannot meet the precision requirements for the glue application of BC solar cells.
