The automatic deviation correction device comprises a fixed base, a deviation correction sensor, a deviation correction driving mechanism, a first deviation correction roller mechanism and a deviation correction roller driving mechanism; the deviation correction driving mechanism comprises a deviation correction roller support and a front-back moving mechanism, wherein the deviation correction roller support can be moved inwards or outwards in the direction perpendicular to the base material conveying direction through the front-back moving mechanism; the first deviation correction roller mechanism is arranged in front of the deviation correction roller support, a second deviation correction roller mechanism is arranged in back of the deviation correction roller support, and the first deviation correction roller mechanism and the second deviation correction roller mechanism comprise lower deviation correction compression rollers, upper deviation correction compression rollers and vertical moving mechanisms, wherein the vertical moving mechanisms can drive the upper deviation correction compression rollers to vertically move and are used for clamping base materials between the upper deviation correction compression rollers and the lower deviation correction compression rollers; the deviation correction roller support is provided with the deviation correction roller driving mechanism used for driving the lower deviation correction compression rollers on the first deviation correction roller mechanism to rotate. The automatic deviation correction device has the advantages of being high in deviation correction reliability and simple in structure.

Description

technical field [0001] The invention relates to a deviation correcting device, in particular to an automatic deviation correcting device for adjusting the position of a lithium battery substrate. Background technique [0002] In the lithium battery winding process, the deviation correction action of the plate substrate before entering the winding directly affects the winding alignment of the battery core, and the automatic deviation correction performance is very important for the quality control of the winding. At present, the deviation correction device used in the industry is set before the pole piece cutter, and it is a deviation correction roller mechanism to correct the deviation. When the substrate is deflected, the substrate often has the same or more deflection within a certain distance upstream. At this time, if there is only one pair of rectifying rollers to rectify the deflection, as the upstream deflected substrate is conveyed, the substrate behind the deflectin...

Problems solved by technology

When the substrate is deflected, the substrate often has the same or more deflection within a certain distance upstream. At this time, if there is only one pair of rectifying rollers to rectify the deflection, as the upstream deflected substrate is conveyed, the substrate behind the deflecting roller The material starts to deflect again in a short period of time, which requires deflection correction. Frequent deflection correction actions reduce the stability of the winding performance of the battery core.
