AI Technical Summary
Existing equipment cannot adjust the position of the suction head according to the different sizes of pouch lithium batteries, resulting in cumbersome operation and low applicability.
An air extraction structure was designed, comprising a support frame, positioning plate, rubber pad, telescopic rod, spring, long bolt, drive motor, hydraulic cylinder, and vacuum pump. Through multi-point positioning and an adjustable suction head, it can achieve precise positioning and air extraction of soft-pack lithium batteries of different sizes.
It enables efficient positioning and venting of soft-pack lithium batteries of different sizes, improves the applicability of the equipment, simplifies the operation process, and avoids local overpressure or underpressure caused by uneven pressure distribution.
