Fully-automatic sticking machine of secondary battery electrode slice insulating tape

Abstract

The invention relates to a fully-automatic sticking machine of a secondary battery electrode slice insulating tape, which comprises a pedestal and mounting blocks, wherein the mounting blocks are positioned at both ends of the pedestal, and a sliding plate is arranged between the mounting blocks; symmetrically distributed conveying rollers are arranged at both sides of each mounting block, and a conveying belt is arranged on each mounting block corresponding to a position between the conveying rollers; a blanking hopper is arranged on the pedestal corresponding to the mounting block at one end; a vertically distributed mounting shell is also arranged on the pedestal; a pole ear position inductor is arranged at the lower part of the mounting shell corresponding to the adjacent conveying belt; an insulating tape charging disk is arranged on the mounting shell; a plurality of insulating tape feed guiding wheels are arranged below the insulating tape charging disk; an automatic insulatingtape conveying mechanism and an insulating tape fusing mechanism are arranged on the mounting shell; an insulating tape fusing cylinder of the insulating tape fusing mechanism is fixed with a connecting block; and symmetrically distributed pole sheet pressing rollers are arranged on the mounting shell corresponding to the other side connected with the blanking hopper. The invention has the advantages of simple and compact structure, high automation degree and accurate sticking position and improves the production efficiency.

Description

technical field [0001] The invention relates to a manufacturing device in the field of chemical power sources, in particular to a fully automatic pasting machine for insulating tapes of secondary battery electrodes, belonging to the technical field of battery machinery manufacturing. Background technique [0002] In the secondary battery manufacturing process, it is required to paste insulating tape on the welding part of the electrode sheet and the current collector to prevent the phenomenon of piercing the separator, causing short circuit and micro short circuit after winding. At present, battery manufacturers all adopt the method of first pulling the insulating tape on the transition plate, then cutting it, and manually using small metal pieces to pick it up one by one and stick it to the two sides of the welding place of the electrode sheet and the current collector. This kind of operation is monotonous and repetitive, the labor intensity is high, and the hands and eyes ...

AI Technical Summary

Problems solved by technology

This kind of operation is monotonous and repetitive, the labor intensity is high, and the hands and eyes are prone to fatigue, so that the paste position deviation is large, and the paste strength is different, which can easily cause short circuit and micro short circuit of the battery, and affect the pass rate of battery production.

This is a labor-intensive, simple and highly repetitive operation with low production efficiency, which seriously affects the development of secondary battery production and the improvement of automation

This seemingly simple operation has not been effectively solved by automation transformation for a long time
