Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-2, in order to solve the above technical problem, the embodiment provides a cell bending jig, which includes a press-fit assembly disposed on a workbench 10, the press-fit assembly includes a cylinder assembly and an elastic plate 20 located above the cylinder assembly, the cylinder assembly on the workbench 10 includes three cylinders 11 distributed at equal intervals, and the elastic plate 20 is rectangular.

In order to fix the elastic plate member 20 and the cylinder 11, three connecting members 21 are fixed on the elastic plate member 20 along the width center line thereof, the connecting members 21 are fixed at the center of the elastic plate member 20 and at both ends of the elastic plate member 20 by bolts, respectively, and the line formed by connecting the three connecting members 21 is the width center line of the elastic plate member 20. The telescopic rod ends of the three cylinders 11 are respectively pivoted with the three connecting pieces 21 through pin shafts 22, the pin shafts 22 are connected to enable the connecting pieces 21 to rotate relative to the telescopic rod ends, and the telescopic rod ends can apply vertical force to the connecting pieces 21 through the pin shafts 22.

The table 10 is provided with a vertical frame 30, a suspension 40 is suspended below the vertical frame 30, the suspension 40 is suspended below the vertical frame 30 via a bearing 41, and the suspension 40 is vertically movable in a reciprocating manner.

In order to realize the pressing with the elastic plate 20 on the working table 10, a pressing assembly is also arranged on the suspension bracket 40, and comprises a cylinder assembly and the elastic plate 20, the cylinder assembly comprises three cylinders 31 fixed on the suspension bracket 40, and the telescopic ends of the cylinders 31 are connected with the connecting pieces 21 which are distributed on the elastic plate 20 at equal intervals. The cylinder 31 fixed to the suspension 40 is disposed symmetrically to the cylinder 11 fixed to the table 10 and is pivoted to the connecting member 21 of the elastic plate member 20 by the pin 22 in the same manner. The two groups of symmetrically arranged pressing components form a pressing structure for pressing the battery.

Further, a drive assembly is provided above the suspension 40 for performing the pressing action. The driving assembly is a driving cylinder 50, the driving cylinder 50 is fixed on the stand 30, and the telescopic end of the cylinder 50 is fixed on the suspension 40 through a bolt. The suspension 40 is arranged below the stand 30 in a sliding manner by two side bearings 41, and the suspension 40 can slide up and down in the vertical direction by the guiding and limiting of the two side bearings 41.

In order to complete the bending operation of the battery cell, the elastic plate 20 provided in this embodiment is made of a memory alloy material, and the exterior of the elastic plate is wrapped by high-quality rubber. The internal composition structure of the memory alloy enables the memory alloy material to have elastic performance and strong recovery capability, and the memory alloy material can recover to the original shape after being bent and deformed, has high strength, can meet the strength requirement of bending of the battery core, is wrapped by rubber, and has the effect of protecting the surface of the battery core.
