Pole piece nip roll correction mechanism

Abstract

The invention relates to a clamp roll deviation rectifying mechanism of a pole piece. The clamp roll deviation rectifying mechanism comprises a clamp piece deviation rectifying part, a guide supporting part, a deviation rectifying driving part, a deviation rectifying sensor and a reset pressing piece part, wherein the clamp piece deviation rectifying part is arranged on the front face of a vertical plate and is provided with a pair of rolling clamp rolls for clamping the pole piece, and the deviation rectifying direction is vertical to the vertical plate; the guide supporting part is vertically arranged on the vertical plate for supporting the clamp piece deviation rectifying part; the deviation rectifying driving part is arranged on the back face of the vertical plate, and the clamp piece deviation rectifying part is driven to perform deviation rectifying movement or reset movement relative to the vertical plate through the guide supporting part; the deviation rectifying sensor is arranged on the front face of the vertical plate for detecting the transverse position of the pole piece through the clamp piece deviation rectifying part relative to the vertical plate and controlling the deviation rectifying direction of the deviation rectifying driving part; and the reset pressing piece part is arranged at one side of the clamp piece deviation rectifying part on the front face of the vertical plate, and the axle of a reset roll is parallel to the axle of the rolling clamp roll for compressing the pole piece tightly when the clamp piece deviation rectifying part is reset. The clamp roll deviation rectifying mechanism has the advantages of low cost and accurate deviation rectifying, and is quick to response and free of wrong operation.

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 deflection correction device before winding in a fully automatic cell winding machine. Background technique [0002] The deviation correction device of the pole piece in the battery production equipment of the prior art is generally that the deviation correction mechanism is directly installed on the vertical plate, and the driving part and the deviation correction part cannot be installed separately, resulting in a redundant structure and an increase in cost; the response is slow, which affects the deviation correction accuracy . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pole piece deflection correcting device before winding of the battery production equipment in view of the above-mentioned deficiencies in the prior art. [0004] Th...
