Embodiment
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with drawings and embodiments.
Referring to Fig. 1 to Fig. 3, the utility model provides a kind of battery crimping unit with bending edge function, includes: the top board 1 that is connected with the bending edge machine, last flap 2, lower platen 3, lower flap portion 4 and cant plate 5.
Described upward flap 2 is positioned at the right side of top board 1, described lower platen 3 and lower flap portion 4 are positioned at top board 1 below, the top of described lower platen 3 and lower flap portion 4 and the bottom connection of top board 1 touch, and the transverse width sum of described lower platen 3 and lower flap portion 4 equals the bottom transverse width of top board 1.
The left side of described lower platen 3 contacts with battery 10 limits, and itself and the contacted upper left corner, battery 10 limits lead angle are fillet.
The upper right corner lead angle of described lower flap portion 4 is a fillet, decides according to the requirement of cell thickness, and the radian scope of this fillet is R0.25~R1.
Described cant plate 5 has arc groove with the top surface that the battery edge joint touches, and according to cell thickness, the radian scope of arc groove is R2~R6.
Described going up between flap 2 and the top board 1 has certain spacing.
In the utility model, described top board 1, last flap 2, lower platen 3, lower flap portion 4 and cant plate 5 all adopt high-termal conductivity and wear-resisting material to make, and for example are steel material.
In order in time to be finalized the design in the battery limit, the utility model also is circumscribed with heat transfer unit (HTU), makes it have the heat setting action on battery limit simultaneously.
Concrete flanging operation of the present utility model is carried out following four steps by the bending edge machine according to operating process drive top board 1, last flap 2, lower platen 3, lower flap portion 4 and cant plate 5 and is finished.
As shown in Figure 1, the course of work of this device is: at first be placed on cell backside on this device up, top board 1 descends, push down battery 10 sides simultaneously with lower platen 3, lower flap portion 4, at this moment the edge part of battery 10 can expose part the right in top board 1 and 4 again, after fixing, at this moment carry out the first step of bending edge and finish, direction of action I direction as shown in the figure.
