Multi-station lamination swinging film covering device and film covering method

Abstract

The invention discloses a multi-station lamination swinging film covering device. The device comprises a diaphragm guide mechanism, a swing table mechanism and a peripheral multi-station lamination bench. The swing table mechanism includes a rotating shaft component which rotates forwardly and reversely within a set angle range, and the rotating shaft component includes a rotating shaft and a rotating plate fixedly connected to the rotating shaft; The swing table mechanism is fixedly installed on any horizontal pedestal through an installation bottom plate arranged at a bottom, and the peripheral multi-station lamination bench is fixedly installed on an upper surface of the rotating plate, and reciprocates with the rotating shaft component. The diaphragm guide mechanism is installed on anend portion near a top film output side of the peripheral multi-station lamination bench so as to guide a diaphragm to flow from a right upper direction of the swing table mechanism. The device of theinvention drags the multi-station lamination bench to horizontally and symmetrically deflect and swing back and forth in a set angle range through the swing table mechanism, and several pole pieces and the diaphragm are covered and spliced at multiple station intervals to achieve a multi-station lamination effect so that lamination efficiency is greatly increased. The lamination bench reciprocates in a arc line swinging mode and a film covering time is saved.

Description

technical field [0001] The invention relates to lithium battery manufacturing equipment, more specifically to a multi-station lamination swing coating device. Background technique [0002] After stacking a pole piece, the stacker needs to cover the upper surface with a layer of diaphragm to separate the positive and negative pole pieces. The film covering action takes a lot of time during the whole stacking process. This device is to reduce the overlay Filming time, especially multi-station simultaneous swing lamination to improve production efficiency. [0003] With the large number of applications of lithium batteries, lithium batteries have a complete and mature process flow from production to production. Among them, in order to separate the positive and negative pole pieces of the battery cell, a diaphragm needs to be covered between the positive and negative pole pieces. [0004] The existing film covering method is the left and right reciprocating movement of the dia...

Problems solved by technology

[0004] The existing film covering method is the left and right reciprocating movement of the diaphragm or the left and right movement of the lamination table. The lamination table moves once in one direction for each pole piece or the film pulling device drives the diaphragm to move in one direction left and right, or the lamination table Swing lamination, and both are single station
