Embodiment Construction

[0015] Embodiments of the invention are described in detail below, but the invention can be practiced in many different ways as defined and covered by the claims.

[0016] Please refer to Figure 1 to Figure 6 As shown, the battery cell stack pressing equipment includes a stacking support table 10, a moving mechanism 40, and a press 20. The press 20 includes a base 201, a guide column 202, a pressure head 204, and a driving mechanism 206. The guide column 202 is fixed on the base 201. Above, the pressure head 204 can slide along the guide column 202 under the driving action of the driving mechanism 206, the moving mechanism 40 can move from the stacking support platform 10 to the base 201, and the battery cell stack can be positioned on the stacking support platform 10 when the moving mechanism 40 When stacked on the moving mechanism 40 , the pressure head 204 is used to compress the battery cell stack arranged on the moving mechanism 40 .

[0017] The battery cell stack pres...
