Financial news on January 8, 2024, according to the announcement of the State Intellectual Property Office, Wuhan Dyer Laser Technology Co., Ltd. has obtained a project entitled "A battery screen printing alignment method and system", authorized announcement number CN116885047B, the application date is September 2023.

The patent abstract shows that the application provides a cell screen printing alignment method and system, which relates to the technical field of solar cell screen printing. Firstly, the coordinate system of the calibration board is obtained, and then the coordinates of the rotation center of the UVW platform in the coordinate system of the calibration board are calculated. Then, the screen plate is calibrated to obtain the coordinates of the center point of the screen plate in the coordinate system of the calibration board and the offset Angle of the screen plate in the coordinate system of the calibration board. Then, the battery plate is fed and calibrated to obtain the coordinates of the center point of the battery plate in the coordinate system of the calibration board. Finally, according to the coordinates of the rotation center of the UVW platform in the coordinate system of the calibration board, the coordinates of the center point of the screen in the coordinate system of the calibration board, the deviation Angle of the screen in the coordinate system of the calibration board, the coordinates of the center point of the battery in the coordinate system of the calibration board and the deviation Angle of the battery in the coordinate system of the calibration board, Align the screen with the battery. In this way, the accuracy of alignment between the screen and the battery before printing can be improved.
