Pole piece moving deviation-rectifying device

Abstract

A pole piece moving deviation-rectifying device is used for secondary deviation rectification of a cell core full-automatic winding machine pole piece. The pole piece moving deviation-rectifying device comprises a substrate of a full-automatic winding machine, which is vertically arranged, a moving deviation-rectifying plate vertically arranged on the front of the substrate, a deviation-rectifying driving mechanism installed on the substrate and a deviation-rectifying sensor installed on the substrate, wherein the substrate is vertically arranged, and the conveying direction of the pole piece is parallel to the plane of the substrate; the moving deviation-rectifying plate is parallel to the substrate, a pole piece driving mechanism and a tension control mechanism sequentially connected with the pole piece driving mechanism and used for the pole piece entering a winding process are arranged on the front of the moving deviation-rectifying plate, and the deviation-rectifying direction is perpendicular to the substrate; the deviation-rectifying driving mechanism is used for adjusting the distance between the moving deviation-rectifying plate and the substrate; and the deviation-rectifying sensor detects the horizontal position of the pole piece output out of the moving deviation-rectifying plate relative to the substrate and is used for controlling the deviation-rectifying driving mechanism. The pole piece moving deviation-rectifying device has the advantages that the pole piece driving mechanism is installed on the moving deviation-rectifying plate, front-and-back movement of the whole pole piece is achieved, and the deviation-rectifying effect is good.

Description

technical field [0001] The invention belongs to the technical field of battery manufacturing, and relates to battery cell production equipment, in particular to a pole piece deviation correcting device in a cell sheet making and winding machine. Background technique [0002] The pole piece deviation correction device in the battery production equipment of the prior art is generally that the pole piece driving mechanism 3 is directly installed on the base plate 1. During the movement of the pole piece 9, it is not conducive to the pole piece deviation correction, and it is easy to cause the pole piece to tear. [0003] And the tension cylinder 42 of the pole piece tension control mechanism 4, the pole piece floating roller 43, the pole piece passing roller 44 and the load cell 45, as well as the pole piece length measuring mechanism 7, the pole piece pressing mechanism 8, etc., are all directly installed on the base plate 1 In fact, during the movement of the pole piece, it ...
