Description

Technical Field

[0001] The utility model relates to the technical field of square shell lithium battery production, in particular to a liquid injection clamp loading and unloading device. Background Art

[0002] According to the current production process of square lithium batteries, due to the limitation of the space of square aluminum shell, the injection time is generally long, so it requires a point-to-point injection needle to complete the injection through a long time. As a result, when the battery fixture is loaded and unloaded, the fixture needs to be pushed out and returned to its position to facilitate the loading and unloading of the battery.

[0003] Currently, in the production process of square lithium batteries, the clamp is pushed out and returned to its original position by installing a slider at the bottom of the clamp and driving the clamp with a cylinder to complete the action. The reliability of this method is relatively poor. The clamp is pushed out over a long distance, and the slider is easily worn, resulting in a shortened life of the slider. At the same time, it is affected by the crystallization of the electrolyte, causing the slider to get stuck and the cylinder to be unable to complete the action, resulting in low production efficiency and inability to meet future production needs.
