Stacking (Disc)

Operation function:

The positive and negative electrode sheets, isolation film, and negative electrode sheets are regularly overlapped by hand or fixture.

1. Equipment function

This machine is mainly used for the lamination of square lithium-ion power battery cells. The working process is as follows: actively roll the diaphragm, through the ferry and tension mechanism, introduce the stack table; the suction cup manipulator moves left and right to drive the diaphragm into Z-shaped movement; the left and right suction cups remove the positive and negative electrode pieces from the two material boxes, and then alternately stacked on the stack table; After the stack, the feeder manipulator takes the core.

Machine performance parameters

• The overall alignment accuracy of the diaphragm is ±3 mm;
• The overall alignment accuracy of the pole sheet is ±3 mm;
• The alignment accuracy of adjacent poles is ±3 mm;
• Production beat: lamination time (1.3-1.5 seconds / number of layers) + ending time (15 seconds);
• Qualified rate: 98% (except for poor incoming materials and misoperation);
• Operating rate: 95% (except for failure within 10 minutes);
• Overall dimensions: 1300 mm (L) 1000mm (W) 2100mm (H) (subject to the final design);
• Power supply: 220VAC ± 5, single-phase, 10 KW;
• Gas source: 0.5~0.6 Kgf / cm², 100 l / min;
• Vacuum source: -0.09MPa, 100 l / min;
• Non-corrosive gas, liquid, and explosive gas;
• Weight: 1500 Kg (bearing ground bearing not less than 500 Kg / m2).

functional characteristics:

• The diaphragm release mechanism is set up with the deviation correction device, using the floating roller to control the diaphragm tension;
• The pole piece handling mechanism is driven by a servo motor with precise positioning;
• There are positive and negative pole plate positioning devices, and the pole plate is positioned by the mechanical secondary positioning mechanism;
• The stack table is set with a precision guidance mechanism to make the laminated table rise and fall in real time according to the laminated thickness;
• The positive and negative electrode pads are designed separately to avoid the mixing of positive and negative materials;
• Take the unloading cell to the unloading station, and collect the cell by manual;
• The equipment has friendly interface, easy to operate, simple maintenance, stable and reliable operation; the top of the equipment has indicator (red: fault green: running yellow: standby); the equipment has maintenance count and prompt function.
