Four-corner rubber coating device for square battery cell

Abstract

The invention belongs to the technical field of battery cell processing, and discloses a square battery cell four-corner rubber coating device which comprises a battery cell supporting assembly and four corner wrapping assemblies. The battery cell supporting assembly is configured to support a battery cell, and gummed paper is adhered to each of four corners of the upper surface of the battery cell; the four groups of corner wrapping assemblies are respectively arranged at the periphery of the battery cell supporting assembly, each corner wrapping assembly comprises a glue stirring block, the glue stirring blocks can be propped against the upper surface of the battery cell, and the four glue stirring blocks are configured to respectively stir the gummed paper adhered to the four corners to be continuously bent so as to sequentially cover the upper surfaces, the side surfaces and the lower surfaces of the corners. According to the four-corner rubber coating device for the square battery cell, the four rubber stirring blocks respectively stir and bend the rubber paper from the four corners of the battery cell at the same time, so that the coating efficiency is high, appearance defects such as edge wrinkling and edge stacking and quality defects are prevented, the coating precision is high, the upper surfaces, the side surfaces and the lower surfaces of the four corners can be subjected to full-coating rubber coating, the consistency is good, and the production efficiency is high. And the product yield and the processing efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of electric core processing, in particular to a four-corner encapsulation device for a square electric core. Background technique [0002] New energy batteries have the advantages of large specific capacity, no pollution, good charge and discharge performance and long service life, and are currently widely used in electric vehicles, industrial power and other industries. The battery cell is the power storage structure of the battery. As an important part of the battery, the safety performance of the battery cell has a great influence on the power efficiency of the battery. Therefore, the battery cell includes an encapsulation process in the process of processing, and the battery cell is covered with adhesive paper to provide insulation and other protective properties for the battery cell. The wrapping of adhesive tape at the four corners of the cell has always been a problem in the industry, because the wra...

AI Technical Summary

Problems solved by technology

The adhesive tape covering the four corners of the battery cell has always been a problem in the industry, because the covering area is small and difficult to operate. If manual covering is used, the consistency is poor, the stability is poor, the yield is low, and it is prone to wrinkles and edge stacking and other appearance defects and quality defects, and some of the existing equipment on the market for encapsulating battery cells is generally used for encapsulating the surface and side of the battery cell, lacking the function of encapsulating the four corners of the square battery cell, and cannot Provide comprehensive protection for the battery cell
