Battery Automatic Assembly Line – Lithium Battery Pack Assembly Solutions
Battery Auto Assembly Line
1. Outline
This is used to perform the following steps for the winding cell or stacked cell: auto heat and cold pressing, short circuit test, multi cell binding, auto tabs trimming, canning, insulating trip mounting, multi-tab welding, tab folding and sealing, laser welding.
- Highly automated without manual operation;
- High speed: 6PPM for 20AH cells;
2. Applied cell specs
| Type | W Cell width(mm) | L Cell length(mm) |
| ZMAO1A | 20-35 | 25-50 |
| ZMBO1A | 35-55 | 40-70 |
3. Function
- Auto heat and cold press: Mechanical arm picks the cells to heat press station—Auto heat press(temperature and pressure are settable)—mechanical arm pick the cells to cold press station for cold press, and apply short circuit test at the same time (water cooling system for cold press station);
- Cell binding: Neatly overlay 5 or N cells together, and then bind them together under certain pressure; Binding type: full turns binding; two side U type binding, or full turns interval binding with 3 tapes and two side U type;
- Auto tabs trimming: shaping the tab bunches automatically and cut them to required size; With auto waste collecting function;
- Auto canning: Fix the cleaned aluminum or steel can to the right position, manipulator will clamp the battery and fill it to the can;
- Auto insulation sheet loading: vibrating disk shake for load; fix the insulation plate to the right position and load it automatically;
- Auto terminal welding: auto battery positioning and ultrasonic welding;
- Auto tab folding and sealing: auto battery positioning, auto tab welding and cap loading;
- Auto laser welding: manipulator fixed battery to right position, turn 90 degrees, and laser head controlled by servo motor moves to weld the cap;
