Description

Technical Field

[0001] The utility model belongs to the technical field of solar cell processing, and specifically relates to a chip splitting device. Background Technique

[0002] A solar cell is a semiconductor thin sheet that can convert solar energy into electrical energy. Different types of solar cells vary in photoelectric conversion efficiency and cost, and are suitable for different application scenarios and market demands. When solar cells are produced, they need to be cut into small pieces to improve utilization. The principle of splitting solar cells mainly utilizes the properties of light, that is, using a laser line or a diamond wire to generate tiny cracks on the surface of the solar cell, applying force at the cracks, and cutting the solar cell into smaller sizes and specifications through physical separation.

[0003] When the existing solar cell splitting device is in use, it usually transports the solar cells through an electric sliding table and a placing plate, making the solar cells contact the laser line, thereby realizing the splitting of the solar cells. However, before the splitting of the solar cells, if dust and impurities adhere to the surface of the solar cells, it will affect the splitting accuracy of the laser line, thereby reducing the splitting effect of the solar cells. For this reason, we propose a chip splitting device. Content of the Utility Model
