AI Technical Summary

Technical Problem

The existing lithium battery pole piece chamfering device has deficiencies in the workpiece loading and unloading design, which makes the placement and fixation of the pole piece inconvenient before and after the chamfering process, and is prone to displacement or falling off, affecting the uniformity and accuracy of the chamfer. In addition, the lack of an auxiliary positioning mechanism makes it difficult to ensure that the center of the pole piece is accurately aligned with the machining center axis, affecting the performance stability of the battery after assembly.

Method used

The dual fixing design of the fixing component and the guide component is adopted. The cooperation of the electric push rod and the guide block ensures that the center of the pole piece is aligned with the machining center axis. The elastic force of the rubber pad and the contraction spring is used to fix the pole piece, thereby improving the stability and positioning accuracy of the pole piece. The processing is carried out in combination with the motor-driven chamfering grinding wheel.

Benefits of technology

It achieves fast and stable fixation of the pole pieces, ensures the uniformity and accuracy of the chamfers, avoids the displacement and falling off of the pole pieces during the processing, and improves the performance consistency and quality of the battery after assembly.

Abstract

The utility model relates to the technical field of lithium battery pole piece processing, in particular to a lithium battery pole piece chamfering device. The technical problems that existing equipment has defects in workpiece assembly and disassembly design, so that the pole piece is not convenient to place and fix before and after chamfering, sometimes, the pole piece is likely to displace and even fall off in the machining process, an operator is difficult to align the center of the pole piece to a machining center shaft of the equipment due to the lack of an auxiliary positioning mechanism, and machining efficiency is poor are solved. The inaccurate positioning can directly influence the quality and the consistency of the chamfer, and further leads to unstable performance after the battery is assembled. According to the technical scheme, the lithium battery pole piece chamfering device comprises a bottom plate. According to the utility model, the positive and negative pole pieces can be quickly fixed through the cooperation of the fixing assembly and the guide assembly, the fixing effect is stable through the double fixation of the fixing assembly and the guide assembly, and the centers of the pole pieces can be aligned with a machining center shaft of equipment through the arrangement of the guide assembly.
