Clamping and transferring device for lithium battery production line

Abstract

The invention discloses a clamping and transferring device for a lithium battery production line. The clamping and transferring device comprises a conveying arm and an automatic clamping mechanism which is slidably installed along the conveying arm in cooperation, and the automatic clamping mechanism comprises a wireless stepping mechanism and a suction mechanism used for clamping lithium batteries. The suction mechanism comprises a gas path pipeline installed at the lower end of the wireless stepping mechanism, at least one set of branch pipes in butt joint with the gas path pipeline, and corrugated hoses which are arranged at the ends of the branch pipes and play a role in buffering suction. The gas path pipeline is connected with negative pressure equipment and is provided with an electric control valve for controlling the circulation state of gas flow, one set of branch pipes are connected by a plurality of sets of reinforcing ribs, a power connection column is fixed on the reinforcing rib close to the corrugated hoses, and the bottom end of the power connection column is provided with a travel switch which abuts against the lithium batteries to close the electric control valve when the corrugated hoses are in a deformation contraction state. According to the clamping and transferring device for the lithium battery production line, negative pressure control can be easily achieved to clamp the lithium batteries by suction or release the lithium batteries, and the operation is convenient, fast and stable.

Description

technical field [0001] The invention belongs to the technical field of lithium battery production, and in particular relates to a clamping and transferring device used in a lithium battery production line. Background technique [0002] Lithium batteries are a type of batteries that use lithium metal or lithium alloys as positive / negative electrode materials and use non-aqueous electrolyte solutions. With the development of microelectronics technology at the end of the 20th century, miniaturized equipment is increasing day by day, which puts forward high requirements for power supply. Lithium batteries have entered a large-scale practical stage. With the increase of market demand, the production scale of lithium batteries has also been continuously expanded, and various types and special-purpose battery structures have been developed. From 18650 cylindrical lithium batteries to subsequent blade batteries, lithium batteries have developed rapidly. with application. [0003]...

AI Technical Summary

Problems solved by technology

[0003] In the transportation of lithium batteries in the lithium battery production line, it is necessary to use a clamping transfer device to adjust and transfer the position of the lithium battery so that it can pass through different production stages, and the existing clamping transfer device structure is suitable for cylindrical lithium batteries. The battery has been improved, but there is a problem that the clamping force is not easy to control when adjusting the transfer of sheet batteries such as blade batteries, and the unloading of the clamping depends on the transmission opening and closing of the mechanical structure, which will affect the clamping position for a long time stability
