Pole piece pushing mechanism of storage battery piece wrapping machine

Abstract

The invention discloses a pole piece pushing mechanism of a storage battery piece wrapping machine, which comprises an ejecting block for pushing a pole piece and multistage linked air cylinder group comprising at least two air cylinders which are connected in parallel, wherein the cylinder body of an air cylinder at a previous stage is driven by the piston of an air cylinder at the next stage; and the initial air cylinder at the first stage drives the ejecting block. When the multistage linked air cylinder group is used, the occupation of the external space of the piece wrapping machine is avoided completely, and the structure of the machine is more compact.

Description

technical field [0001] The invention relates to the technical field of battery manufacturing, in particular to a pole piece pushing mechanism of a battery wrapping machine. 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. Sheet" or "pack board" process. In the traditional "wrapping" process, manual operations are mostly used, which is not only inefficient, but also the quality of the wrapping is not high, and the lead dust falling on the pole piece will also affect the health of the operating workers. The existing open automatic wrapping machine has adopted a mechanical structure to realize the pushing process of the pole piece before wrapping. In order to ensure that the pole piece can have enough power to fully be...

Problems solved by technology

In the traditional "wrapping" process, manual operations are mostly used, not only the efficiency is low, but the quality of the wrapping is not high, and the lead dust falling on the pole piece will also affect the health of the operators.

The existing open automatic wrapping machine has adopted a mechanical structure to realize the pushing process of the pole piece before wrapping. In order to ensure that the pole piece can have enough power to fully bend the indentation of the separator paper, the cylinder for pushing the pole piece is required to have The longer booster stroke, the use of a single cylinder drive will inevitably occupy the outer space of the wrapping machine and destroy the overall structure of the wrapping machine
