I. production process requirements:
1. Equipment function: conduct z-type lamination of power cell.
2. Applicable product specifications:
Specification of adaption pole:
Model W cell width (mm) L cell length (mm) H cell thickness (mm)
A 90, 130, 6.2
II. Equipment performance
1. Alignment accuracy between poles: overall <0.5mm, single slice <0.3mm;
2. Alignment accuracy between pole and diaphragm: center deviation <0.5mm;
3. Stacking speed: 1.5-2s/tablet;
4. There are laminated setting parameters in the man-machine interface;
5. Diaphragm constant tension device;
6. Error display and prompt function;
7. It has the function of dusting and removing static electricity
8. The upper plate can work for about 1 hour at a time
III. Device function unit
Laminating machine equipment layout and process description
1. The process diagram of the battery cell after making. After the cell is folded, the membrane shall be outsourced and the adhesive paper shall be pasted.
FIG. P11.1 process diagram of battery cell after manufacture
2. The whole machine includes: left and right pole film box (2 on each side), left and right secondary positioning (2 on each side) main laminating platform (1 on each side), pole piece abdicating mechanism, rear moving mechanism, main transmission mechanism, control system, etc.
3. Each time the machine drives 200mm back and forth, the moving time is 0.7 seconds, and the upper and lower positioning of the cylinder takes 0.35 seconds respectively, that is, 1.4 seconds for each stack.
4. The main laminating platform does not move, and the diaphragm rotates around. There are 2 sets of primary positioning and secondary positioning of the pole, and the pole box device on the right can be lowered.
5. On the right side of the pole piece box can move, the agency is to batteries volume diaphragm spacetime out a larger space. Agencies before and after the move, does not affect the pole piece boxes around, using servo motor and mobile devices, moving up and down quickly and positioning, USES the servo mechanism, material box moved back and forth on top of pole piece adopts servo mechanism, the positioning device, a tiny cylinder to positioning, positioning plate under a vacuum adsorption function.
6. Laminated device: vacuum sucker sucked the pole piece to lamination machine, this position has a clamping cylinder pressure plate and diaphragm, Lord laminated stationary, fold the piece on the number of set pieces. Laminated the audience have a pressure bomb and servo mechanism to ensure that knife work every time in the same height, with pressure to ensure that batteries remain the state of compression, use servo down to control the increase of the thickness of the batteries;
7. Release diaphragm device: the device has dc motor, constant tension mechanism and reasonable standard roller installation to ensure that the torque of diaphragm is basically the same when rotating;
8. Main transmission device, which has a 1.5kw servo motor, precision ball screw, precision bearings, fast acceleration of starting and stopping, accurate positioning.
