The second worm gear assembly 15 is connected to a bidirectional threaded rod 16 via a connecting shaft. Two second sliders 17 are threaded onto the outer surface of the bidirectional threaded rod 16. Two grooves 19 are provided at the bottom of the second fixed frame 12. Connecting rods 18 are fixedly connected to the bottom ends of the two second sliders 17, passing through the grooves 19. Fixing blocks 20 are fixedly connected to the two connecting rods 18 via bolts and nuts. Clamping tools 21 are fixedly connected to one end of each fixing block 20. The copper rod body 10 is then inserted into the machine. In set 8, the third motor 14 drives the second worm gear assembly 15, which in turn drives the bidirectional threaded rod 16 to rotate via the connecting shaft. The bidirectional threaded rod 16 drives the second slider 17 to move, which in turn drives the connecting rod 18 to move. The groove 19 limits the connecting rod 18, which in turn drives the fixing block 20 to move. The fixing block 20 drives the clamping tool 21 to move, which clamps the copper rod body 10. The inner surface of the clamping tool 21 is provided with a soft pad to prevent damage to the copper rod body 10.

[0027] The above structure, through the cooperation of the third motor 14, the bidirectional threaded rod 16 and the clamping tool 21, achieves a stable clamping of the copper rod, while avoiding damage to the surface of the copper rod during the clamping process.

[0028] A fourth fixing frame 22 is fixedly connected to the top of the base 1. A fourth motor 23 is fixedly connected to the inner wall of the fourth fixing frame 22. A third worm gear assembly 24 is fixedly connected to the output end of the fourth motor 23. A rotating shaft 25 is fixedly connected to the connection point of the third worm gear assembly 24. A mold 26 is fixedly connected to one end of the rotating shaft 25. A receiving platform 27 is fixedly connected to the top of the base 1. A first electric push rod 28 is fixedly connected to the top of the receiving platform 27. A first fixing clamp 29 is fixedly connected to the telescopic end of the first electric push rod 28. A second electric push rod 30 is fixedly connected to the top of the receiving platform 27. A second fixing clamp 31 is fixedly connected to the telescopic end of the second electric push rod 30. When the clamping tool 21 clamps the copper rod body 10, the first electric push rod 28 drives the first fixing clamp 29 to fix the copper rod body 10. Then, the second electric push rod 30 drives the second fixing clamp 29 to fix the copper rod body 10. The clamp 31 fixes the copper rod body 10. The fourth motor 23 is started, which drives the third worm gear assembly 24. The third worm gear assembly 24 drives the rotating shaft 25 to rotate, and the rotating shaft 25 drives the mold 26 to rotate. Due to the fixation of the first fixing clamp 29 and the second fixing clamp 31, the rotation of the mold 26 will bend the copper rod body 10 for the first time. The second motor 6 is started, which drives the first worm gear assembly 7 to rotate. The first worm gear assembly 7 drives the machine sleeve 8 to rotate through the connecting shaft. The machine sleeve 8 drives the copper rod body 10 to rotate. At the same time, the first motor 3 drives the first slider 4 to move a certain distance in the slide groove 2 through the connecting shaft. The clamping tool 21, the first fixing clamp 29, the second fixing clamp 31, the fourth motor 23, and the third worm gear assembly 24 operate repeatedly, which can realize the bending of the copper rod body 10 at different angles at intervals.

[0029] The above structure, through the cooperation of multiple motors, electric push rods and mold 26, enables precise bending of copper rods at multiple angles and positions, meeting the complex requirements of lithium battery production.

[0030] Working Principle: A copper rod bending machine for lithium batteries operates as follows: First, the copper rod body 10 is inserted into the machine sleeve 8. The third motor 14 is started, driving the bidirectional threaded rod 16 to rotate via the second worm gear assembly 15. This causes the two second sliders 17 to move closer together, thereby clamping and fixing the copper rod body 10 via the connecting rod 18 and the fixing block 20. Then, the first electric push rod 28 and the second electric push rod 30 respectively drive the first fixing clamp 29 and the second fixing clamp 31 to further fix the copper rod body 10. The fourth motor 23 is started, driving the rotating shaft 25 and the mold 26 to rotate via the third worm gear assembly 24, performing the first bend on the copper rod body 10. To bend at different positions or angles, the second motor 6 is started, rotating the copper rod body 10 to adjust the angle. Simultaneously, the first motor 3 moves the first slider 4 in the groove 2 to adjust its position. Repeating the clamping and bending operations allows for multi-angle, multi-position bending of the copper rod.
