2、Equipment introduction

2.1Equipment Overview

This equipment is mainly used for the "Z" shaped lamination of prismatic battery.

 

2.2 workflow

2.2.1 the separator is actively unwinded and introduced into the lamination table through the tension mechanism.

2.2.2 the lamination table drives the separator to move back and forth to place the electrode.

2.2.3 two sets of manipulator suction cups respectively take the negative sheet and the positive sheet after bag making out from the two material boxes on the left, and stack them on the lamination table after mechanical positioning.

2.2.4. The two stations stack the film at the same time. After the lamination is completed, the electric core is successively transferred to the gluing station by the manipulator to realize automatic side gluing; Start the next one at the same time

Automatic lamination of cells.

2.2.5 after gluing, complete automatic stacking and receiving at the same time.

  

2.3 Equipment characteristics

2.3.1 separator mechanism: active unwinding; Tension control; separator correction; separator alignment accuracy +/-0.3mm;

2.3.2 lamination accuracy: ensure the overall accuracy of the electrode in the lamination to reach +/-0.3mm through the precise positioning of the electrode;

2.3.3 lamination efficiency: lamination speed can reach 0.5s-0.8s/pcs;

2.3.4 dust protection: the material box and pre positioning are equipped with effective dust protection hoods;

2.3.5 electrode angle detection: detect the electrode angle to prevent the electrode angle from being folded into the cell after abnormal folding;

2.3.6 prevent the detection of the missing angle of the tab of the electrode, and prevent the electrodes such as the closing and pulling of the tab of the electrode and the missing angle from being stacked into the electric core;

2.3.7 detect the direction of the tab to prevent the electrode from stacking into the electric core after the tab is reversed;

2.3.8 in particular, the bottom of the cell is a continuous two-layer separator.
