[0022] Example 1

[0023] like Figures 1-2 As shown, a laser welding device includes a mounting base 1, a positioning component 2, and a welding component 3. The positioning component 2 and the welding component 3 are mounted on the mounting base 1. The positioning component 2 is used to place the product to be welded, and the welding component 3 is used to weld the product placed on the positioning component 2. This solution stably sets the welding component 3 and the positioning component 2 with the product on the mounting base 1, enabling the welding component 3 to stably weld the product.

[0024] Multiple welding components 3 are disposed on the mounting base 1, and the welding components 3 are evenly distributed on the side of the positioning component 2. In this embodiment, three welding components 3 are provided, and the three welding components 3 are evenly distributed along the circumferential direction on the outside of the positioning component 2. By using multiple evenly distributed welding components 3, multiple weld points can be uniformly welded to the product on the positioning component 2 at one time.

[0025] Example 2

[0026] like Figures 1-2As shown, the welding assembly 3 in this embodiment includes a welding torch 31 and a mounting bracket 32. The welding torch 31 is mounted on the mounting base 1 via the mounting bracket 32, and the welding torch 31 points towards the positioning assembly 2. The welding torch 31 is mounted on the mounting base 1 via the mounting bracket 32, so that the installation position and orientation of the welding torch 31 can be adjusted simply by adjusting the position of the mounting bracket 32, without the need for manual operation of the welding torch for welding.

[0027] Mounting bracket 32 ​​includes an adjustment structure for adjusting the position of the welding torch. The adjustment structure includes a displacement stage for adjusting the welding torch in the X and Y directions and a rotatable connecting member. The axis of the rotatable connecting member is set horizontally. The position and angle of the welding torch 31 relative to the mounting base 1 are adjusted by the adjustment structure.

[0028] This embodiment also includes a display component 8, which is connected to a camera and is used to monitor the welding position of the welding torch 31 and the product.

[0029] It also includes a start button 6, which is located on the mounting base 1 and electrically connected to multiple welding torches 31. The start button 6 is used to simultaneously start the welding torches 31 for welding. Setting the start button 6 to control the welding torches 31 at the same time improves the welding efficiency of the welding torches 31.

[0030] Example 3

[0031] like Figures 1-3 As shown, the positioning component 2 in this embodiment includes a rotating table 21 and a clamp 22 placed above the rotating table 21. The rotating table 21 is connected to the mounting base 1 via a transmission connection, and the clamp 22 rotates synchronously with the rotating table 21. The rotation of the rotating table 21 causes the product clamped by the clamp 22 to rotate. By changing the rotation angle of the product, the welding component 3 can perform welding on the product at multiple positions under fixed conditions.

[0032] The rotary table 21 is provided with a handle 23 on its exterior. The handle 23 provides additional gripping points, making it easier and less strenuous to drive the rotary table 21 to rotate by the handle 23.

[0033] The mounting base 1 also includes two stops 4, which are located on both sides of the rotary table handle 23. The stops 4 are used to constrain the rotation angle of the handle 23. The stops 4 are covered with urethane sleeves, which can play a role in cushioning and noise reduction.

[0034] Example 4

[0035] like Figure 3As shown, the embodiment further provides arc-shaped constraint blocks 211 on the mounting base 1, which are arranged circumferentially along the rotating table 21, and the inner wall of the arc-shaped constraint blocks 211 is provided with a sliding groove, and the rotating table 21 is provided with a sliding constraint member on the side edge, and when the rotating table 21 rotates, the sliding constraint member installed on the rotating table 21 is in sliding cooperation with the arc-shaped constraint blocks 211.

[0036] In order to prevent the rotating table 21 from swinging in the axial direction during rotation, which causes the rotating process of the rotating table 21 to be unstable, the sliding constraint member of the embodiment includes a roller plunger 212, which includes an elastic adjusting column and a roller connected to the output end of the elastic adjusting column, and the roller is in sliding cooperation with the sliding groove of the arc-shaped constraint blocks 211, so that the roller can move along the fixed track, and the axial movement of the roller is constrained by the sliding groove of the arc-shaped constraint blocks 211, which can prevent the rotating table from swinging up and down.

[0037] In order to accurately position the rotating table 21 during work, and prevent the rotating table 21 from rotating during welding, the sliding constraint member of the embodiment further includes a positioning column 213, and the output end of the positioning column 213 is provided with an elastic ball head, and the sliding groove of the arc-shaped constraint blocks 211 that cooperates with the positioning column 213 is provided with a positioning pin hole, when the positioning column 213 cooperates with the sliding constraint block, when the positioning column 213 slides on the groove, the elastic ball head of the positioning column retracts, when the positioning column 213 slides to the positioning pin holes on both sides of the groove, the elastic ball head pops out, and the elastic ball head is clamped into the positioning pin hole, and the elastic ball head is constrained in the positioning pin hole, which not only makes the rotating table 21 stable, but also enables the rotating table 21 to be accurately positioned.

[0038] In order to accurately control the rotation angle of the rotating table 21, the embodiment provides a plurality of positioning pin holes on the sliding groove of the arc-shaped constraint blocks 211 that cooperates with the positioning column 213, and the rotation angle of the positioning column 213 between the positioning pin holes is further controlled by controlling the arc length between the positioning pin holes, so that the rotation angle of the rotating table 21 is controllable. In order to constrain the overall rotation angle of the rotating table 21, the stop block 4 is arranged to constrain the handle 23 of the rotating table, and the positions of the positioning pin holes at both ends of the groove are arranged to be the positions constrained by the stop block 4, which ensures that the handle 23 can only rotate within a fixed angle, and the limit of the rotation of the handle 23 constrained by the stop block 4 indicates that it is in place.

[0039] Embodiment 5

[0040] As Figures 1-3As shown, the clamp 22 of the embodiment is provided with a heating assembly 5, and the heating assembly 5 is electrically connected with a temperature controller 7. The heating assembly 5 heats the clamp, so that the temperature of the heating is transmitted to the product installed on the clamping assembly.
