(5) Polar ear reconstruction
(7) The test voltage
The cylinder drives the shaping block to shape the position after laser welding, and the shaping pressure is adjustable.
The cell is pressed and fixed, and the electrode ear of the cell is tested for voltage. The display screen is controlled to distinguish between qualified and unqualified voltage of the cell. After that, the battery is collected and separated manually.
(7) Turntable system
This component is driven by a turntable and consists of a jacking mechanism. In the jacking state, the rotary table rotates to ensure the rotation of the fixture and the cell at each station is smooth, and there is no collision with other components. Turn to the next station when the turntable drops, each station to operate.
