When the pneumatic cylinder drives the connecting piece 102 to perform the lifting action, the clamping plate 103 is driven to rotate around the support plate 104 to realize the tightening and loosening actions of the busbar on the material preparation platform 10. Through the setting of the clamping mechanism, the position accuracy of the busbar can be guaranteed, the use space above the material preparation platform 10 is increased, the structure is simple, and the subsequent manual installation, maintenance and maintenance are facilitated.

[0029] According to Figure 4 As shown in the figure, due to the difference in the width size of the busbar for welding, in order to enable the material preparation platform 10 to be compatible with busbars of different sizes while guaranteeing the positioning of the busbar, a plurality of oppositely arranged waist holes 201 are opened on the upper surface of the material preparation platform 10, the waist holes 201 are arranged obliquely with respect to the pulling direction of the busbar, and five threaded holes 202 are further opened in the waist holes 201, and the threaded holes 202 are used to install positioning pieces 203; through the obliquely arranged waist holes 201 on the upper surface of the material preparation platform 10, the threaded holes 202 are opened in the waist holes 201, the positioning pieces 203 can be selected to be installed in the threaded holes 202 at different positions according to busbars of different sizes, and the sizes of various busbars are compatible. In order to further guarantee the position accuracy of the pulled busbar, two suction holes 204 are opened on the material preparation platform 10 along the pulling path of the busbar, and a negative pressure cavity is further opened in the material preparation platform 10 at the position of the suction hole 204, and the negative pressure cavity is communicated with the suction hole 204; through the setting of the suction hole 204, the busbar can be continuously adsorbed during the pulling process, and the position accuracy of the busbar is guaranteed.

[0030] According to Figure 5As shown, the busbar clamping device further comprises a bending clamping mechanism, wherein the bending clamping mechanism is provided with two groups of lower parts arranged at two ends of the material preparation platform 10, and the bending clamping mechanism comprises a driving mechanism 301, a connecting seat 302 and a bending clamping assembly. Specifically, the bending clamping assembly comprises a bending clamp plate 303 and a connecting block 304. In actual use, the driving mechanism 301 is a cylinder, which is connected to the bottom of the material preparation platform 10 through the connecting seat 302. The connecting block 304 is installed on the output end of the cylinder.
