[0002] Cylindrical batteries are mainly composed of an outer shell, a cap, a positive electrode and a negative electrode. The positive electrode and the negative electrode are connected to the positive electrode ear and the negative electrode ear respectively. The positive electrode is welded to the cap through the positive electrode ear, and the negative electrode is welded to the bottom of the outer shell through the negative electrode ear. The cap is tightly covered at the opening of the outer shell. During the production process of cylindrical batteries, the ear and the cap need to be welded together by welding equipment.

[0003] Most of the existing battery cap connector welding machines are turntable type. All jigs are fixed on the periphery of the turntable, the tube shell and the cap are placed in the jig, and the turntable is rotated to make the laser welding gun perform welding in sequence. During welding, it is difficult to ensure the accuracy of the cap position. The battery is directly placed inside the jig and is not fixed. During the rotation process from the turntable to the position below the welding gun, it is easy to shake and shift the position, which causes the welding position of the welding gun to deviate, affecting the quality of the produced batteries.

[0020] The welding mechanism includes a first electric push rod 7 fixedly mounted on the lower surface of the mounting plate 6, and a laser welding gun 8 is fixedly connected to the lower surface of the output end of the first electric push rod 7. The extension and retraction of the output end of the first electric push rod 7 can press the lifting and lowering of the laser welding gun 8, thereby facilitating welding of batteries according to the height of the battery model.

[0021] The clamping mechanism includes a U-shaped plate 13 fixedly connected to the output end of the second electric push rod 12, and a bidirectional screw 15 is rotatably connected to the inner side of the U-shaped plate 13. Correspondingly, a micro motor 14 is fixedly installed on the back side of the U-shaped plate 13, and the output end of the micro motor 14 extends through the inner side of the U-shaped plate 13 and is fixedly connected to one end of the bidirectional screw 15, and the outer surface of the bidirectional screw 15 is symmetrically sleeved with sliders 16 connected by threads, one side of the outer surface of the two sliders 16 is slidably connected to the inner side of the U-shaped plate 13, and the other side of the outer surface of the two sliders 16 is fixedly connected to an arc-shaped clamping plate 17. The operation of the micro motor 14 can drive the rotation of the bidirectional screw 15, so that the two sliders 16 slide toward each other or away from each other along the inner side of the U-shaped plate 13, respectively, so that the two arc-shaped clamping plates 17 can clamp or loosen the battery.

[0022] A servo motor 9 is fixedly installed on the upper surface of the workbench 1, and the output shaft of the servo motor 9 is fixedly connected to a turntable 10, and a plurality of sleeves 11 are fixedly connected to the upper surface of the turntable 10, wherein the servo motor 9 should use a stepper motor commonly used in the prior art, so as to brake its output shaft to rotate a certain angle each time, and the interior of the sleeve 11 can be used to place batteries, and the operation of the servo motor 9 can drive the rotation of the turntable 10 of its output shaft, thereby driving the plurality of sleeves 11 to make circular motion around the center of the turntable 10.

When the servo motor 9 drives the turntable 10 to rotate and a sleeve 11 on the upper surface of the turntable 10 is displaced to a position directly below the laser welding gun 8, the brake servo motor 9 stops running and starts the second electric push rod 12 and the first electric push rod 7. The extension of the output end of the second electric push rod 12 can push the U-shaped plate 13 to one side of the battery. Subsequently, by starting the brake micro motor 14, the rotation of the bidirectional screw 15 can be driven, so that the battery is clamped by two arc-shaped clamping plates 17 and placed in the center of the sleeve 11, which can avoid the laser welding gun 8 from welding in the wrong position and improve the welding accuracy. The quality of the produced battery is guaranteed. Correspondingly, when the output end of the first electric push rod 7 drives the laser welding gun 8 downward to weld the battery, i.e., the cap, the clamping mechanism can also fix the battery, and the welding effect is better and more practical.
