Abstract

The invention relates to an automatic electrode clamp opening and closing device for the formation of a lithium battery. The device comprises a cylinder, first sliding blocks, second sliding blocks, a first sliding plate and a second sliding plate. The cylinder is fixed on a support plate. A connecting block is arranged on the head part of a piston rod of the cylinder. The first sliding plate is arranged on the first sliding blocks, and the second sliding plate is arranged on the second sliding blocks. The connecting block is connected with the first sliding plate through a first motion mechanism, and is connected with the second sliding plate through a second motion mechanism. When the cylinder does piston motion, the first and second sliding blocks are driven by the first and second sliding plates to do linear motion along the support plate, and only motion towards or away from each other in motion. At least one stirring fork for stirring an electrode clamp is arranged on the first sliding plate. Stirring forks of which the number is the same as that of the stirring forks on the first sliding plate are arranged on the second sliding plate. The stirring forks on the first and second sliding plates are arranged in pairs. By the device, the electrode clamps can be automatically opened and closed.

Description

technical field [0001] The invention relates to the technical field of formation of lithium batteries, in particular to an automatic opening and closing device for electrode clips suitable for an automatic production line of formation of lithium batteries. Background technique [0002] The demand for batteries for new energy vehicles has risen suddenly. The battery formation process is an important link in the production of battery products and the main factor affecting the quality of batteries. The entire formation process of automotive lithium batteries generally takes 10-15 days. The battery needs to be charged and discharged several times in stages. It is clamped and loosened by the electrode clip many times, so the opening and closing operation of the electrode clip is a basic operation in the lithium battery formation process. The mode of manual opening and closing of the clamps in the manual formation equipment affects the consistency of the clamping performance of t...
