Under the action of the reset spring, the limit plate will rebound to the initial position. The lower pressure rod will squeeze the limit spring during the upward movement, forcing the limit spring to retract toward the adjustment plate. After the limit plate is pressed down, the battery to be welded is placed on the upper surface of the limit plate for limiting, ensuring that the welding result is more accurate. The limit ball can limit the downward pressure and rebound of the limit plate, and the limit spring will extend or retract according to the up and down movement of the lower pressure rod to limit the position of the limit plate.

[0029] Example:

[0030] New energy battery cell production side panel welding equipment, a workbench 11 is welded on one side surface of the welding machine body 1, an X-axis guide rail 14 is fixedly installed on the upper surface of the workbench 11, and a movable column 6 is movably installed on the upper surface of the X-axis guide rail 14, a fixed disk 5 is fixedly installed on the upper surface of the movable column 6, a fixed plate 15 is fixedly installed on the upper surface of the fixed disk 5, an adjusting plate 16 is fixedly installed on the lower surface of the fixed plate 15, the surface of the fixed plate 15 is movably connected to the limiting plate 12, the lower surface of the limiting plate 12 is fixedly installed with a lower pressure rod 20, the surface of the lower pressure rod 20 is movably inserted with a reset spring 21, and the surface of the reset spring 21 is movably connected to the limiting ball 17.

[0031] When welding side panels of commonly used battery cells, the batteries are usually placed on the welding plate. During the welding process, there may be a large displacement phenomenon, which leads to a decrease in the quality of welding. This device presses down the limit plate 12 before placing the battery. Under the action of the limit spring 19, the limit ball 17 can limit the lower pressure rod 20. When the welding work is completed, the limit plate 12 can be pressed down again. Under the action of the reset spring 21, the limit plate 12 will rebound to the initial position. The lower pressure rod 20 will squeeze the limit spring 19 during the upward movement, forcing the limit spring 19 to retract toward the adjustment plate 16. After the limit plate 12 is pressed down, the battery to be welded is placed on the upper surface of the limit plate 12 for limiting, ensuring that the welding result is more accurate.

[0032] The surface of the adjustment plate 16 is provided with a movable hole 18, and a limit spring 19 is provided on the surface of the movable hole 18. The end of the limit spring 19 is fixedly mounted with a limit ball 17. The limit ball 17 limits the downward pressure and rebound of the limit plate 12. The limit spring 19 extends or retracts according to the upward and downward movement of the pressing rod 20, thereby limiting the position of the limit plate 12.

[0033] A rotating motor 22 is fixedly mounted on the inner wall of the movable column 6, and a fixed plate 5 is fixedly mounted on the upper surface of the rotating motor 22. The operator can start and stop the rotating motor 22 through the control panel. The rotating motor 22 controls the rotation of the fixed plate 5, thus preventing the operator from repeatedly adjusting the position of the battery, which would affect the quality of the battery side plate welding, and improving welding efficiency.

[0034] A suction cup 7 is fixedly mounted on the lower surface of the welding machine body 1. The suction cup 7 can provide stability to the overall device and improve the accuracy of welding.

[0035] A welding support plate 3 is fixedly mounted on the upper surface of the welding machine body 1. A welding pneumatic structure 2 is fixedly mounted on the upper surface of the welding support plate 3. A laser welder 4 is provided at one end of the welding pneumatic structure 2. Laser welder 4 uses a high-energy-density laser beam to weld, achieving uniform, defect-free welds and ensuring the strength and stability of the weld points, thereby improving the reliability of the battery module. This not only enhances welding quality and production efficiency, but also reduces thermal impact and material damage.

[0036] A control panel 13 is fixedly mounted on the upper surface of the welding machine body 1. The control panel 13 can control parameters such as temperature, time, and current during the welding process to ensure welding quality and efficiency. By accurately controlling these parameters, problems such as overheating, overcooling, or unstable current during the welding process can be avoided, thereby improving welding quality.

[0037] A connecting shaft 10 is provided at the edge of the upper surface of the welding machine body 1. A protective plate 9 is fixedly mounted on one side of the connecting shaft 10. Heat dissipation holes 8 are provided on the surface of the welding machine body 1 adjacent to the protective plate 9. The design of the heat dissipation holes 8 helps to form a natural ventilation channel, improve the heat dissipation capacity of the equipment, and thus optimize the overall performance of the equipment.

[0038] The implementation principle of the embodiment of the new energy battery cell production side plate welding equipment of this application is:

[0039] The limiting ball 17 can limit the downward pressure and rebound of the limiting plate 12, and the limiting spring 19 will extend or retract according to the up and down movement of the lower pressure rod 20 to limit the position of the limiting plate 12.

[0040] The operator can start and stop the rotary motor 22 through the control panel, which controls the rotation of the fixed plate 5. This prevents the operator from repeatedly adjusting the battery position, which could affect the quality of the battery side plate welds, thereby improving welding efficiency. The laser welder 4 uses a high-energy-density laser beam to weld, achieving uniform, defect-free welds and ensuring the strength and stability of the weld points, thereby improving the reliability of the battery module. This not only improves welding quality and production efficiency, but also reduces thermal effects and material damage.
