Abstract
Description
Technical Field
[0001] The utility model relates to a clamp, in particular to a tab pressing pneumatic clamp. Background Art
[0002] The tab (TAB) is an important component of the bare cell. As a metal conductor connecting the electrode sheet and the terminal inside the battery, it gathers and conducts the current on the current collector inside the battery. It is the contact point of the positive and negative electrodes of the battery during charging and discharging, and it is also a bridge between the cell current and the outside of the cell. During the winding process of the bare cell, the tab is sent to the pole piece position through the unwinding, conveying and clamping mechanism, and then the tab is cut after ultrasonic high-frequency vibration welding. However, the tab clamping mechanism often gets stuck, resulting in the tab not being sent to the designated welding machine position, resulting in poor welding such as cold welding, over-welding, and sticking film. What is more serious is that the pole piece is welded broken, resulting in pole piece fracture. Pole piece fracture and poor welding directly lead to the scrapping of the bare cell, causing huge losses and waste in terms of time and cost. In order to solve this problem, a tab clamping pneumatic clamp is designed to perfectly solve the waste caused by the clamping problem. Utility Model Content

[0005] Preferably, the U-shaped connecting frame performs back-and-forth reciprocating motion.
