U-shaped automatic piece wrapping machine for pole pieces of storage batteries

Abstract

The invention discloses a U-shaped automatic piece wrapping machine for pole pieces of storage batteries, comprising a piece wrapping mechanism for wrapping a first pole piece, an assembly mechanism connected with the discharge end of the piece wrapping mechanism, a first piece supply mechanism for supplying the first pole piece to the piece wrapping mechanism and a second piece supply mechanism for supplying the second pole piece to the assembly mechanism, wherein the second pole piece and the wrapped first pole piece are piled up at intervals in the assembly mechanism to form a pole group. The machine realizes automatic feeding and automatic wrapping of the pole pieces and automatic assembly of the wrapped pole pieces, completes the whole operation process in a streamline manner in one step and improves the wrapping efficiency and quality of the pole pieces. Improvement of the degree of automation is conductive to correspondingly reducing the probability of manually contacting the pole pieces, thus greatly reducing the harm of lead dust to the operators.

Description

technical field [0001] The invention relates to the technical field of battery manufacturing, in particular to a wrapping machine capable of wrapping battery pole pieces and assembling them into pole groups. Background technique [0002] In the current battery production process, there is a process of assembling the positive electrode sheet, negative electrode sheet, and separator paper into an electrode group. The separator paper is sandwiched between the positive electrode sheet and the negative electrode sheet, so the industry usually calls it " In the "wrapping" or "wrapping" process, the way of wrapping is generally divided into U-type, W-type and I-type. However, in the traditional "wrapping" process, manual operations are mostly used. Taking the U-shaped wrapping method as an example, the operator first takes a piece of negative electrode, and wraps both sides of the positive electrode with cut separator paper. The positive electrode sheet is stacked on the negative ...

Problems solved by technology

Therefore, compared with the traditional wrapping method, the above-mentioned patent only relies on the machine to automatically complete the wrapping process of the separator paper on the pole piece, and the pole piece feeding and assembly process has not yet got rid of the manual operation mode.
