Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] For an example, please refer to... Figures 1-4 A laser welding device for battery top cover includes a guiding mechanism 1. The guiding mechanism 1 includes a support member, on which a first guide rail 103 is provided. A first slide block 104 is slidably connected to the first guide rail 103, and a lifting part is provided on the top of the first slide block 104. The lifting part is connected to a clamping part, which clamps a handheld laser welding head 2. The first guide rail 103 and the first slide block 104 cooperate to guide the handheld laser welding head 2 when it moves. This allows the handheld laser welding head 2 to move linearly along the first guide rail 103, which to some extent offsets the influence of hand tremors on the welding process. It ensures that the laser beam always acts accurately on the welding part of the battery top cover according to the preset path during the welding process, reduces the influence of human factors on welding accuracy, improves welding quality, and reduces the risk of battery performance problems and safety accidents caused by inaccurate welding.

[0027] Furthermore, the support includes a support rod 101, and a first guide rail 103 is mounted on the top of the support rod 101. The support rod 101 is used to support the first guide rail 103, and the first guide rail 103 is connected to the support rod 101 by welding or bolting.

[0028] Furthermore, support seats 102 are provided at both ends of the support rod 101. The support seats 102 are used to support the support rod 101 to improve the stability of the support rod 101. The bottom of the support seat 102 is provided with anti-slip texture, which can improve the stability of the support seat 102 when placed on the support surface.

One end of the hand-tightening bolt 111 abuts against the side of the support plate 105 away from the second guide rail 106. When the hand-tightening bolt 111 is tightened, it abuts against the support plate 105, which can fix the height of the second slide 107. Loosening the hand-tightening bolt 111 can release this fixation, thereby pushing the second slide 107 to move up and down. The second slide 107 is welded together with the connecting frame 110 and the first clamp 108.

[0031] Furthermore, the clamping part includes a first clamp 108 connected to the second slide 107, and a second clamp 109 is provided on the side of the first clamp 108 away from the second slide 107.

[0032] Furthermore, the first clamp 108 and the second clamp 109 are provided with slots on their adjacent sides, and the shape and size of the slots are adapted to the shape and size of the handle of the handheld laser welding head 2, thereby facilitating the clamping and fixing of the handle of the handheld laser welding head 2 by the first clamp 108 and the second clamp 109.

[0033] The first clamp 108 and the second clamp 109 only hold the two handles of the handheld laser welding head, and the handles still have space for the user to hold.

[0034] When in use, loosen the hand-tightening bolt 111 and move the handheld laser welding head 2 vertically. Adjust the height of the handheld laser welding head 2 according to the actual situation. After adjustment, tighten the hand-tightening bolt 111, then hold the handle of the handheld laser welding head 2 and press the switch of the handheld laser welding head 2. Then push the handheld laser welding head 2 horizontally along the first guide rail 103 to perform laser welding.
