Design requirements for fully automatic square battery assembly line
1.1. This plan is based on the battery assembly requirements provided by * * * battery co., LTD., and designs the square type battery automatic production line.
1.2. Production line capacity requirements: the whole production speed of the automatic battery assembly line is about 25PPM;
1.3. Applicable battery size: battery length: 36 ~ 80mm, battery width: 30 ~ 70mm, battery thickness: 3.0 ~ 10mm
1.4. Battery assembly production process: from raw material feeding to flip up - positioning repeatedly straight pole ear - stick tape to cover gasket, plastic bags and head to flip the blanking - battery feeding - bottom glue - into the shell - positioning clamping and cutting extremely ear to ear cover plate ultrasonic welding, resistance welding 1-2 - tensile testing - resistance welding reverse feeding to cover plate flattening, bending pole ears to block to short circuit test, laser spot welding, battery.
1.5. Control system: the system is composed of four sets, including a gasket packing system, a glue-in-shell system, a pole ear inspection and welding system, and a pole ear bending and sealing system. Each set of system is independently controlled by PLC.
1.6. Square battery automatic assembly line component equipment:
| NO. | Process Name | Device name | Equipment capability | note |
| 1 | feeding | Automatic feeder | 25ppm | |
| 2 | Gasket pack adhesive | Cell gluing machine | 25 PPM | Contain polar ears repeatedly straight, into the gasket, tape |
| 3 | Into the shell | Cell feeder | 25 PPM | |
| 4 | Pole ear welding inspection | Pole ear cover plate welding machine | 25 PPM | Detection of length and distance of pole ear and elimination of defective products |
| 5 | Cover plate | Pole ear bending capping machine | 25 PPM | Contains the pole lug bending, sealing, laser spot welding anti - rebound |

2.2. Laminating machine
2.2.1. Design requirements
2.2.1.1. The machine is suitable for packing the rubber of the square type battery with good tape and gasket.
2.2.1.2. Process flow: charging the electric cell → feeding the aluminum shell at the same time → coating adhesive → clamping positioning → positioning the aluminum shell → feeding the shell (pushed in three times) → feeding.
2.2.1.3. Features: the shell is guided through a funnel guide. Into the shell push into three times, the first two for the clamping push, the last one for the direct push. The shell is loaded by stepping double-position magazine.
2.2.1.4. The length of adhesive paper on the left and right sides after the roll core is glued is L4:0.2 ~ 1mm
2.2.1.5. The two sides of the reel are symmetrical, with an absolute difference of 0 ~ 3mm
2.2.1.6. The diaphragm paper cannot be turned out to the core after the roll core is glued (the diaphragm paper is bent to the inside of the roll core without exposing the diaphragm)
2.2.1. 7. The pole piece and diaphragm will not be damaged after the roll core is glued
2.2.1.8 when entering the shell, there should be a guide groove between the coil core and the shell mouth
2.2.1.9. The coil core positive and negative ears do not bend during the process of sticking the bottom glue and entering the shell
2.2.1.10 after entering the shell, the Angle between the coil core and the side of the shell is ≤ 50
2.2.1.11. The distance between the coiling core and the inner wall of the shell bottom after entering the shell shall be L3:0.5±0.2mm
2.2.1.12. The distance between the coil core and the two edges of the shell L1 and L2 requires: ≥0.1mm
2.2.1.13. The difference of the distance between the reel core and the edge of the shell | l1-l2 | ≦1.5mm
2.2.1.14. After the coil core enters the shell, it can automatically test the distance between the exposure of the negative ear and the shell mouth, and determine OK or NG
2.2.1.15. Production qualification rate ≥ 99.8%
2.2.1.16. Production yield ≥ 95%.
2.2.1.17. The operation time of switching model should not exceed 30min
