A sealing welding tray mechanism

Abstract

The invention discloses a sealed welding tray mechanism, which comprises a base and a clamping part arranged on the upper end of the base, and the clamping part includes a lengthwise clamping part, a widthwise clamping part and a heightwise clamping part. The clamping part in the longitudinal direction includes a fixed plate fixedly connected with the base, the upper end of the fixed plate is slidably connected with a first push plate, and the clamping part in the width direction includes a second push plate slidably connected with the base. The clamping part in the height direction includes a fixed support fixedly connected to the base, and a third push plate is movably connected to the top of the fixed support. This application divides the clamping and positioning of the tray into length aspects according to the clamping requirements of square aluminum shell batteries. The positioning and clamping mechanism, the positioning and clamping mechanism of the width and the positioning and clamping mechanism of the height are three independent subsystems to ensure that the positioning and clamping of the battery do not affect each other, improve the effect of clamping and positioning, and ensure the consistency of positioning.

Description

technical field [0001] The invention relates to the technical field of battery processing equipment, in particular to a sealing welding tray mechanism. Background technique [0002] The sealing of lithium-ion battery hard-shell cells after liquid injection has always been the core technical link of cell production. Sealing after liquid injection currently has two common means of sealing steel balls and welding sealing sheets, both of which can achieve the purpose of sealing. According to the process requirements, the sealing steel ball is selected, and there are currently problems with the pass rate and stability. Seal welding is still the main mode of operation for prismatic batteries. [0003] As a sealed welding tray after secondary liquid injection, it needs to have a certain degree of clamping redundancy according to the size deviation of the length, width and height of the battery; and due to the switching of battery products, the battery tray also needs to be replac...

Problems solved by technology

[0003] As a sealed welding tray after secondary liquid injection, it needs to have a certain degree of clamping redundancy according to the size deviation of the length, width and height of the battery; and due to the switching of battery products, the battery tray also needs to be replaced, which leads to the use of battery trays. The rate is not high, the processing cost is high, etc.
