Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of pole piece assembling equipment, in particular to a kind of positive and negative plate laminating device. BACKGROUND

[0002] In the current battery production process, one process is to assemble positive pole piece, negative pole piece and separator paper into pole group, and the separator paper is sandwiched between the positive pole piece and the negative pole piece, so it is commonly called "packing piece" or "packing plate" process in the industry. The traditional "packing piece" process is mainly operated by hand. The operator first takes a piece of negative pole piece, sandwiches the positive pole piece with the cut separator paper on both sides and stacks it on the negative pole piece, ensuring that there is separator paper between each set of positive and negative pole pieces. The above operation is repeated to complete the entire packing piece and assembly. Not only is the efficiency low, but the quality of the packed pieces is also not high, and the lead dust falling from the pole pieces can also affect the health of the operators. In order to improve production efficiency, yield and protect the health of workers, existing battery manufacturers have developed packing equipment for sandwiching separator paper and pole pieces, and laminating devices for stacking packed pieces and pole pieces into pole groups. However, the existing laminating device is prone to separator paper scattering during production, resulting in low production yield. SUMMARY

[0003] The utility model provides a kind of positive and negative plate laminating device;Solve the problem that laminating device is prone to separator paper scattering in the prior art during production.
