Pole piece after-shear control method and pole piece after-shear machine

Abstract

The invention provides a pole piece after-shear control method and a pole piece after-shear machine. A pole piece is driven by a main shaft to move, and an auxiliary shaft drives a slicer for shearingthe pole piece to move. The pole piece after-shear control method comprises the following steps: detecting whether a detection signal sent is received or not when a lug position detection device detects a lug on the pole piece; if so, controlling the main shaft to accelerate by taking the rotating speed of the main shaft in a uniform stage as a target rotating speed value; and when the rotating speed of the auxiliary shaft reaches the target rotating speed value, controlling the slicer to shear the pole piece. When the detection signal of the lug position detection device is received, the rotating speed of the auxiliary shaft which drives the slicer to move pursue the rotating speed of the main shaft which drives the pole piece to move. When the rotating speed of the main shaft is equal to that of the main shaft, that is, the slicer and the pole piece are relatively stationary, the slicer is controlled to shear the pole piece, so that the technical effects of shorting the pole piece shearing time and improving the pole piece shearing efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of lithium battery pole piece cutting, in particular to a pole piece chasing shearing control method and a pole piece chasing shearing machine. Background technique [0002] Due to the rapid development and wide application of lithium battery technology, the requirements for the winding quality and efficiency of lithium batteries are getting higher and higher. The existing pole piece cutting is to suspend the winding when the pole piece of the battery core is turned to the corresponding position, and then the manipulator module Cutting off, this method takes a long time and is inefficient, and cannot meet the increasing demand for production tasks. Contents of the invention [0003] In view of this, the object of the present invention is to provide a pole piece tracking shearing control method and a pole piece tracking shearing machine, so as to alleviate the technical problems of long time-consuming pole ...
