Description

Technical Field

[0001] The utility model relates to the technical field of battery pole piece processing, in particular to a battery pole piece flattening machine. Background Art

[0002] Solar cells are generally divided into single crystal silicon, polycrystalline silicon, and amorphous silicon. Single crystal silicon solar cells are the fastest-developed solar cells at present. Their structure and production process have been finalized, and the products have been widely used in space and on the ground. This type of solar cell uses high-purity single crystal silicon rods as raw materials. In order to reduce production costs, solar cells used on the ground use solar-grade single crystal silicon rods, and the material performance indicators have been relaxed. The existing battery poles need to be flattened during the production process. The current flattening device may cause the pole to turn outward due to excessive speed, while too slow speed will reduce production efficiency and cause the pole to be not handled smoothly. Therefore, a battery pole flattening machine is designed, which can control the upper and lower kneading belts to knead and flatten the poles, which can improve the continuity, uniformity, and leveling effect of production and processing.
