[0058] As a preferred embodiment of the present invention, Figure 3 As shown, the rotary preloading mechanism 5 includes a workbench 501, an annular shell 502 is fixed to the upper end of the workbench 501, a rotating disk 503 is arranged in the annular shell 502, the edge of the annular shell 502 is provided with a U-shaped groove 504 with an opening facing upward, the end of the nut sorting path 2 is connected to the U-shaped groove 504, and a plurality of grooves 505 are evenly arranged along the circumferential direction at the edge of the upper end surface of the rotating disk 503. Whenever the rotating disk 503 rotates a certain angle, there will be a groove 505 connected to the U-shaped groove 504, so that the nuts on the nut sorting path 2 can enter the corresponding groove 505; a motor is fixed to the lower end of the workbench 501, and the output shaft of the motor is connected to the rotating disk 503 through a connecting shaft.

[0059] A proximity switch 506 is provided on the side wall of the annular shell 502. The proximity switch 506 is used to accurately control the rotation angle of the rotating disk 503. Whenever the rotating disk 503 rotates a certain angle, one of the grooves 505 can reach the specified position, that is, directly below the transfer clamp cylinder 507. In this way, the nut in the groove 505 can correspond to the position of the battery rod, thereby realizing automatic assembly of the battery rod and the nut.

[0060] Preferably, a blanking plate 6 is provided on one side of the workbench 501 , and the assembled battery rods and nuts are blanked through the blanking plate 6 .

[0061] The working principle of the automatic assembly device of battery pull rod and nut of the utility model is as follows:

[0062] The nuts are sorted and arranged in a queue in the annular vibrating disk 1 and transported to the groove 505 of the rotating disk 503 through the nut sorting track 2 under the action of the first oscillator;

[0063] The battery rods are sorted into a queue in the rod sorting mechanism 3. Specifically, after being placed in the hopper 302, the battery rods are moved from the bottom of the reciprocating plate 303 to the first transmission belt 304 at the top. They are then conveyed to the end of the first conveyor belt 304 via the first conveyor belt 304. The elbows of some battery rods are hooked onto the rod sorting assembly 305 for sorting into a queue. The remaining battery rods fall onto the second conveyor belt 306 and are conveyed back to the hopper 302 via the second conveyor belt 306.

[0064] The lifting cylinder 410 is used to lift the battery rods forming a queue on the rod sorting assembly 305 and send them to the clamping cylinder 405 to clamp the elbow of the battery rod. Under the drive of the piston rod of the translation cylinder 403, the clamping cylinder 405 moves horizontally and sends the battery rod to the transfer clamp cylinder 507 for clamping. Then the clamping cylinder 405 returns to its original position. At the same time, under the action of the translation cylinder 403, the third connecting plate 408 is controlled to move until the tightening cylinder 409 clamps the elbow of the battery rod. At this time, the transfer clamp cylinder 507 is loosened, and the tightening cylinder 409 is controlled to move downward by the piston rod of the lifting cylinder 406, so that the lower part of the battery rod rotates against the nut on the rotating disk 503. After the rotation is completed, the battery rod and the nut are automatically assembled. Finally, the lifting cylinder 406 controls the tightening cylinder 409 to drive the assembly up and down, and unloads the material through the blanking plate 6.

[0065] After completing an assembly, the rotating disk 503 is driven by the motor to rotate a certain angle, so that the next groove 505 with a nut is in the specified position (the specified position refers to the position directly below the transfer clamp cylinder 507), and continues to complete the assembly with the next pull rod. And so on. After completing an assembly, the rotation angle of the rotating disk 503 is precisely controlled by the contact switch 506 set on the outer wall of the annular shell to achieve high efficiency of assembly.
