Products Description
Placed in the glove box, the equipment is mainly used to glue the positive and (lithium) negative electrode sheet and the isolation film of the metal lithium negative electrode cell to make a Z-shaped laminated film to make a battery cell.
The lithium anode uses a single-layer sheet box to be manually switched as a loading positioning platform. The box and positioning platform are positioned by pins and moved to the loading position (the lithium anode sheet box is completed in another process); it is also compatible with secondary battery carbon anodes. Material box (multi-layer sheet material).
The positive electrode pick-up mechanical arm mechanism uses vacuum to pick up the electrode pieces in the positive electrode trough, and the secondary positioning correction mechanism accurately positions them;
The positive and negative electrode sheets are alternately placed on the stacking table; the stacking table moves back and forth between the two robotic arms in conjunction with the movements of the two robotic arms, so that the isolation film forms a Z-shape to separate the positive and negative electrode sheets; the equipment moves in such a cyclical manner to achieve the polar assembly When the number of laminated sheets reaches the set value, the cell transfer manipulator will send the pole group clamp to the (reserved length of the rolled separator) cutter to cut the separator, and the manipulator rotates to the cell unloading position, and the equipment Automatically enter the assembly of the next pole group;
The cells are collected manually, and the diaphragm is finished and glued manually.
