Technical Field
[0001] The invention belongs to the technical field of battery cell sintering, and in particular relates to a battery cell grid line sintering process. Background Art
[0002] The cell grid wire sintering device is a production equipment designed specifically for solar cells. Its core function is to sinter the grid wire electrodes on the cell and the silicon wafer under high temperature to ensure stable ohmic contact between them. The device usually includes key components such as the furnace body, heating system, transmission device and exhaust system.

This process is crucial to improving the conversion efficiency and stability of solar cells. It is an indispensable part of the solar cell manufacturing process. The cell grid wire sintering device provides strong support for the development of the solar industry with its efficient and precise process characteristics.
[0003] In the process of implementing this application, it was found that the technology has the following problems: the traditional battery cell grid line sintering device is not equipped with a refractory jacket, and the heat in the environment is difficult to dissipate evenly, resulting in local excessive temperature, which may affect the sintering quality and even damage the battery cell. At the same time, there is no component for automatically collecting dust and debris, which easily causes dust to pollute the environment.
[0004] Therefore, a cell grid line sintering process is proposed. Summary of the invention
[0005] The purpose of the present invention is to ensure uniform heat dissipation in the environment, automatically collect dust and debris, and improve the environmental friendliness of equipment production. The present application provides a cell grid line sintering process.

Since the outer surfaces of the driving gear shaft and the driven gear shaft are meshed with the inner surface of the second transmission toothed belt, and the inner surface of the first transmission toothed belt is meshed with the outer surfaces of the multiple groups of driven gears and the driving gear, the rotation of the driving gear shaft can drive the corresponding multiple groups of rotating rods to rotate, thereby effectively transmitting the battery cell.

By starting to heat the multiple groups of electric heating tubes to heat the inside of the device, the refractory jacket and the multiple groups of heat transfer grooves ensure that the heat in the environment is evenly dissipated, thereby ensuring the sintering quality. At the same time, the exhaust gas inside the equipment is quickly driven to leave the chamber by the suction pump, so as to maintain air circulation in the furnace body and avoid the exhaust gas from polluting the battery cell.
[0014] 2. In the present invention, after sintering is completed, the corresponding first screw is started to rotate. Since the outer periphery of the first screw is connected to a group of threaded sleeves for rotation, the rotation of the first screw can drive the corresponding scraper to move laterally. The top of the scraper effectively scrapes the dust and debris on the outer surface of the multiple groups of feed rollers. The dust and debris reach the pulling groove at the bottom. By starting the corresponding third motor, the second screw connected to the output end is rotated. Since the outer periphery of the second screw is connected to a group of threaded sleeves for rotation, the rotation of the second screw can drive the corresponding cleaning part to clean the dust and debris inside the pulling groove from right to left. After cleaning, the debris reaches the inside of the collection box through the material guide groove for collection, thereby protecting the production environment and preventing it from adversely affecting the quality of the battery cells.
