Abstract

The invention discloses a sucker jig, a pole piece conveying method and lamination equipment. The sucker jig comprises a sucker body with a suction surface and an elastic separating piece connected with the sucker body. Through staggered arrangement of the multiple layers of pole pieces on the pole piece tray, the active separation function of the elastic separation piece is matched, and batch buffering and accurate single piece suction of the pole pieces are realized. When the sucker rises, the compressed elastic separating piece applies separating thrust to the lower pole piece through elastic recovery, so that a plurality of pieces are prevented from being sucked. The multi-layer buffer memory of the pole piece tray solves the problem that the cutting end and the lamination end are mutually restricted in the traditional single piece conveying, the decoupling operation of the two ends is realized, the active separation mechanism of the elastic separation piece ensures the accurate absorption of the single piece, the lamination quality defect is avoided, and the high-speed lamination requirement is met.

Description

Sucker jig, pole piece conveying method and lamination equipment Technical Field The invention relates to the technical field of lithium battery manufacturing, in particular to a sucker jig, a pole piece conveying method and lamination equipment. Background In the lithium battery manufacturing process, the cutting, conveying and lamination of the pole pieces are key procedures. After the pole pieces are cut and molded, the pole pieces need to be transferred to a conveying line from a cutting station through a mechanical arm, then the pole pieces are conveyed to a lamination station through the conveying line, and finally, the pole pieces with good products are fed to a lamination station through the mechanical arm to be stacked. The traditional pole piece conveying system adopts a single-piece conveying mode, namely the pole pieces are arranged in a single-layer overlapping way on a conveying line, and the mechanical arm needs to suck and transfer piece by piece. The conveying mode has the defects that when the lamination end is in fault and stagnation, the pole pieces are accumulated on the conveying line due to station limitation of the conveying line, so that the cutting end is forced to stop, otherwise, when the cutting end is in fault, the lamination end enters a stagnation state after the pole pieces on the conveying line are consumed, and the continuity and efficiency of the whole production line are seriously affected. In addition, the conventional single-layer overlapped pole piece arrangement mode has the risk of sucking multiple pieces in the feeding process. Although the existing manipulator is additionally provided with auxiliary actions of preventing sucking multiple pieces, such as blowing, shaking and the like, the situation that two or more pieces of pole pieces are sucked at one time is still difficult to completely avoid in actual production, and the quality defect of a laminated battery core can be caused, so that the consistency and the safety of a battery are affected. With the rapid development of the new energy automobile industry, the productivity and quality requirements on lithium batteries are continuously improved, the traditional single-sheet conveying lamination method cannot meet the efficiency requirements of the current high-speed lamination equipment, and a novel pole piece conveying scheme is required to be developed so as to meet the production requirements of high efficiency and high reliability.
