Description

Technical Field

[0001] This utility model relates to the technical field of laser welding, and in particular to a laser welding machine for battery assembly. Background Technology

[0002] New energy batteries, also known as power batteries, require welding equipment for welding during assembly.

[0003] Among existing laser welding machines used for battery assembly, such as the welding device for assembling new energy batteries disclosed in utility model patent application number 202310912354.2, this invention can automatically clean the dust on the new energy battery and extract the welding fume during the welding process, avoiding the problem of welding fume causing harm to the health of workers, and has a high degree of automation; at the same time, there is no need to transport and handle the new energy battery during operation, which effectively improves welding efficiency.

[0004] However, during laser welding, the battery's position cannot be accurately located when it is brought into contact with the laser, which can easily cause the battery to shift. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a laser welding machine for battery assembly, which can fix and limit the welding of batteries during the laser welding process by setting a clamping mechanism and a contacting mechanism, thereby reducing battery displacement and improving welding accuracy.

[0006] This utility model discloses a laser welding machine for battery assembly, including a lifting mechanism; it also includes a welding mechanism, a limiting mechanism, two sets of clamping mechanisms and two sets of contacting mechanisms. The welding mechanism is installed on the lifting mechanism, the limiting mechanism is installed on the lifting mechanism, the two sets of clamping mechanisms are installed on the lifting mechanism, and each set of clamping mechanisms is equipped with a set of contacting mechanisms.

[0007] The lifting mechanism performs lifting and lowering, the welding mechanism performs welding, the limiting mechanism performs limiting, the clamping mechanism performs clamping, and the contacting mechanism makes contact. By opening the lifting mechanism, the equipment is lowered; the limiting mechanism limits the battery; the limiting mechanism drives the clamping mechanism to clamp the battery; simultaneously, the contacting mechanism makes soft contact; and by opening the welding mechanism, the battery is welded. This allows for fixed and limited welding of the battery during laser welding, reducing battery displacement and improving welding accuracy.

[0008] Preferably, the lifting mechanism includes a vertical frame, a lifting cylinder, and a movable frame. The lifting cylinder is installed at the lower end of the vertical frame, and the movable frame is installed at the lower end of the lifting cylinder. The movable frame is lowered by opening the lifting cylinder.

[0009] Preferably, the welding mechanism includes two sets of equipment frames, two sets of laser welding heads, a bidirectional lead screw, and a motor. The two sets of equipment frames are slidably mounted on a movable frame, and a set of laser welding heads is installed at the lower end of each set of equipment frames. The bidirectional lead screw is rotatably mounted on the movable frame, and the bidirectional lead screw is threadedly engaged with both sets of equipment frames. The motor is installed at the right end of the movable frame, and the output end of the motor is connected to the input end of the bidirectional lead screw. By turning on the motor, the bidirectional lead screw is driven to rotate. While rotating, the bidirectional lead screw engages with the equipment frame, causing the equipment frame to move and position for welding. Welding is then performed by turning on the laser welding heads.

[0010] Preferably, the limiting mechanism includes a limiting frame, four sets of sliding rods and four sets of springs. The limiting frame is slidably mounted on the movable frame via the four sets of sliding rods, and the limiting frame is connected to the movable frame via the four sets of springs. The limiting frame limits the battery by lowering the movable frame, and the limiting frame is reset by the springs.

[0011] Preferably, the clamping mechanism includes a gripper and a connecting plate. The gripper is rotatably mounted on the movable frame, and the connecting plate is rotatably mounted on the limiting frame. The gripper and the connecting plate are rotatably connected. The connecting plate is driven by the movable frame descending and the limiting frame rising, so that the connecting plate presses against the gripper and the gripper clamps the battery.

[0012] Preferably, the contacting mechanism includes a sliding frame, two sets of springs, and an airbag. The sliding frame is slidably mounted on the gripper via the two sets of springs, and the airbag is mounted on the sliding frame. When the gripper clamps the material, the airbag contacts the battery, while the springs support the sliding frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by opening the lifting mechanism to lower the equipment, by using the limiting mechanism to limit the battery, by using the limiting mechanism to drive the clamping mechanism to clamp the battery, by using the contact mechanism to make soft contact, and by opening the welding mechanism to weld the battery, the battery can be fixed and limited during the laser welding process, reducing battery displacement and improving welding accuracy.

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0020] Example 1

[0021] like Figures 1 to 4 As shown, a laser welding machine for battery assembly includes a lifting mechanism 1, a welding mechanism 2, a limiting mechanism 3, two sets of clamping mechanisms 4 and two sets of contacting mechanisms 5. The welding mechanism 2 is mounted on the lifting mechanism 1, the limiting mechanism 3 is mounted on the lifting mechanism 1, the two sets of clamping mechanisms 4 are mounted on the lifting mechanism 1, and each set of clamping mechanisms 4 is equipped with a set of contacting mechanisms 5.

[0022] The lifting mechanism 1 performs lifting, the welding mechanism 2 performs welding, the limiting mechanism 3 limits movement, the clamping mechanism 4 clamps, and the contacting mechanism 5 makes contact.

[0023] The lifting mechanism 1 includes a frame 11, a lifting cylinder 12, and a movable frame 13. The lifting cylinder 12 is installed at the lower end of the frame 11, and the movable frame 13 is installed at the lower end of the lifting cylinder 12.

[0024] The welding mechanism 2 includes two sets of equipment frames 21, two sets of laser welding heads 22, a bidirectional lead screw 23, and a motor 24. The two sets of equipment frames 21 are slidably mounted on the movable frame 13. Each set of equipment frames 21 has a set of laser welding heads 22 mounted at its lower end. The bidirectional lead screw 23 is rotatably mounted on the movable frame 13, and the bidirectional lead screw 23 is threadedly engaged with both sets of equipment frames 21. The motor 24 is mounted on the right end of the movable frame 13, and the output end of the motor 24 is connected to the input end of the bidirectional lead screw 23.

[0025] The limiting mechanism 3 includes a limiting frame 31, four sets of sliding rods 32 and four sets of springs 33. The limiting frame 31 is slidably mounted on the movable frame 13 through the four sets of sliding rods 32, and the limiting frame 31 is connected to the movable frame 13 through the four sets of springs 33.

[0026] The clamping mechanism 4 includes a gripper 41 and a connecting plate 42. The gripper 41 is rotatably mounted on the movable frame 13, and the connecting plate 42 is rotatably mounted on the limiting frame 31. The gripper 41 and the connecting plate 42 are rotatably connected.

[0027] The contact mechanism 5 includes a sliding frame 51, two sets of springs 52 and an airbag 53. The sliding frame 51 is slidably mounted on the gripper 41 by the two sets of springs 52, and the airbag 53 is mounted on the sliding frame 51.

[0028] By opening the lifting cylinder 12, the moving frame 13 is lowered, which in turn limits the battery to the limiting frame 31. The limiting frame 31 is reset by the first spring 33. The lowering of the moving frame 13 and the rising of the limiting frame 31 drive the connecting plate 42, causing the connecting plate 42 to press against the gripper 41, which clamps the battery. At the same time, the gripper 41 clamps the material, causing the airbag cushion 53 to contact the battery. Meanwhile, the second spring 52 supports the sliding frame 51. By opening the motor 24, the bidirectional lead screw 23 is driven to rotate. As the bidirectional lead screw 23 rotates, it engages with the equipment frame 21 through a threaded connection, allowing the equipment frame 21 to move and position for welding. Welding is then performed by opening the laser welding head 22. This process allows for fixed and limited welding of the battery during laser welding, reducing battery displacement and improving welding accuracy.

[0029] like Figures 1 to 4 As shown, this utility model discloses a laser welding machine for battery assembly. During operation, the lifting cylinder 12 is opened to lower the moving frame 13, which in turn limits the battery to the limiting frame 31. The limiting frame 31 is reset by spring 33. The lowering of the moving frame 13 and the rising of the limiting frame 31 drive the connecting plate 42, causing the connecting plate 42 to press against the clamping claw 41, which clamps the battery. At the same time, the clamping claw 41 clamps the material, causing the airbag cushion 53 to contact the battery. Meanwhile, the sliding frame 51 is supported by spring 52. The motor 24 is turned on to drive the bidirectional lead screw 23 to rotate. As the bidirectional lead screw 23 rotates, it engages with the equipment frame 21 through a thread, moving the equipment frame 21 to position the welding position. Welding is then performed by opening the laser welding head 22.

[0030] The lifting cylinder 12, laser welding head 22, and motor 24 of this utility model are commercially available. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0031] The main function achieved by this utility model is: during the laser welding process, by setting a clamping mechanism and a contact mechanism, the battery can be fixed and limited during the laser welding process, reducing battery displacement and improving welding accuracy.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
