One end of the carrier plate 320 is connected to the first slide plate 310, and the other end extends horizontally and is suspended. The laser 330 is carried on the carrier plate 320. The carrier plate 320 is provided with a first through hole 321.

[0032] It is understandable that in some embodiments of the present invention, reference Figure 3 and Figure 4The fixing assembly 400 includes a second slide plate 410 and a pressing plate 420. The second slide plate 410 slides with the slide rail 200. One end of the pressing plate 420 is connected to the second slide plate 410, and the other end extends horizontally and is suspended. When the pressing plate 420 descends, the pressing plate 420 can press the workpiece to fix the workpiece. A second through hole 421 is formed through the pressing plate 420. The second through hole 421 is aligned with the first through hole 321 so that the laser can pass through the second through hole 421. When the workpiece needs to be laser welded, the second slide plate 410 slides with the slide rail 200 to drive the pressing plate 420 to descend and press the workpiece, thereby fixing the workpiece. At this time, the laser is emitted by the laser 330, and the laser passes through the first through hole 321 and the second through hole 421 in sequence to achieve laser welding of the workpiece.

[0033] It is understandable that in some embodiments of the present invention, reference Figure 3 and Figure 4 The welding control mechanism also includes a first driving component 500 and a second driving component 600. The first driving component 500 and the second driving component 600 are both arranged on the base plate 100.

[0034] It is understandable that in some embodiments of the present invention, reference Figure 3 and Figure 4 The first driving assembly 500 includes a first driving member, a first screw rod 520 and a first connecting block 530. The first driving member is disposed at one end of the bottom plate 100. The first screw rod 520 is disposed along the length direction of the slide rail 200. The first driving member can drive the first screw rod 520 to rotate. The first connecting block 530 is fixedly connected to the second slide plate 410. A first screw hole is formed through the first connecting block 530. The first screw rod 520 is threadedly engaged with the first screw hole. When the first driving member drives the first screw rod 520 to rotate, the first screw rod 520 is threadedly engaged with the first screw hole, so that the first connecting block 530 drives the second slide plate 410 to slide relative to the slide rail 200, so as to realize the lifting and lowering of the pressure plate 420.

[0035] It is understandable that in some embodiments of the present invention, reference Figure 3 and Figure 4, the first driving member is a first motor 511, the first motor 511 is arranged at the top of the bottom plate 100, and the first screw rod 520 is fixedly connected to the output shaft of the first motor 511. It should be noted that in the present embodiment, the first slide plate 310 is located between the second slide plate 410 and the first motor 511, and a first space 700 is formed between the first slide plate 310 and the bottom plate 100, so that one end of the first screw rod 520 is connected to the first motor 511, and the other end passes through the first space 700, and the end passing through the first space 700 is threadedly engaged with the first connecting block 530. Therefore, when it is necessary to fix the workpiece, when the first motor 511 drives the first screw rod 520 to rotate, the first screw rod 520 is threadedly engaged with the first screw hole, so that the first connecting block 530 drives the second slide plate 410 to slide relative to the slide rail 200, so that the pressing plate 420 descends to press the workpiece, thereby fixing the workpiece.

[0036] It is understandable that in some embodiments of the present invention, reference Figure 3 and Figure 4 The second driving assembly 600 includes a second driving member, a second screw rod 620 and a second connecting block 630. The second driving member and the first driving member are arranged at the same end of the bottom plate 100. The second screw rod 620 is arranged along the length direction of the slide rail 200. The second driving member can drive the second screw rod 620 to rotate. The second connecting block 630 is fixedly connected to the first slide plate 310. A second screw hole is provided through the second connecting block 630. The second screw rod 620 is threadedly engaged with the second screw hole. When the second driving member drives the second screw rod 620 to rotate, the second screw rod 620 is threadedly engaged with the second screw hole, so that the second connecting block 630 drives the first slide plate 310 to slide relative to the slide rail 200, so as to realize the lifting and lowering of the bearing plate 320.

[0037] It is understandable that in some embodiments of the present invention, reference Figure 3 and Figure 4 The second driving member is a second motor 611, and the second motor 611 and the first motor 511 are arranged side by side at the same end of the bottom plate 100, so that the structure of the welding control mechanism is more compact and standardized, and the problem of the large space occupied by the welding control mechanism is further solved. The second screw rod 620 is fixedly connected to the output shaft of the second motor 611, so that when it is necessary to adjust the different welding focal lengths of the laser 330 for different workpieces, the second screw rod 620 is driven to rotate by the second motor 611, and the second screw rod 620 is threadedly matched with the second screw hole, so that the second connecting block 630 drives the first slide plate 310 to slide relative to the slide rail 200, so as to realize the lifting and lowering of the bearing plate 320, thereby changing the distance between the laser 330 and the workpiece, and realizing the adjustment of the welding focal length of the laser 330.

[0038] It is understandable that in some embodiments of the present invention, reference Figure 3 and Figure 4 The end of the bottom plate 100 away from the first motor 511 is provided with a first limit block 810, and the first screw rod 520 is rotatably connected to the first limit block 810, and the first limit block 810 is used to limit the moving position of the second slide plate 410. The bottom plate 100 is also provided with a second limit block 820, and the second limit block 820 is located between the first slide plate 310 and the second slide plate 410, and the second screw rod 620 is rotatably connected to the second limit block 820, and the second limit block 820 is used to limit the moving position of the first slide plate 310, and at the same time, the second limit block 820 limits the moving position of the second slide plate 410, so as to prevent the first slide plate 310 from contacting the second slide plate 410, thereby preventing the welding assembly 300 from contacting the fixing assembly 400.

[0039] It is understandable that in some embodiments of the present invention, reference Figure 3 and Figure 4 A dust suction tube 900 is provided on the pressing plate 420, and one end of the dust suction tube 900 is located at the second through hole 421. The dust suction tube 900 is used to absorb the debris generated during laser welding of the workpiece. Therefore, when the laser 330 performs laser welding on the workpiece, the laser passes through the first through hole 321 and the second through hole 421 to perform laser welding on the workpiece. At this time, debris is easily generated and affects the effect of laser welding. Therefore, the dust suction tube 900 is used to absorb the debris at the second through hole 421 to maintain normal irradiation of the laser, thereby improving the effect of laser welding.

[0040] It is understandable that in some embodiments of the present invention, reference Figure 3 and Figure 4 , a blowing member is provided on the second slide plate 410, and the blowing member is used to clean the debris between the first through hole 321 and the second through hole 421. Specifically, the blowing member is a wind knife 411, and the wind knife 411 is arranged horizontally. There are two wind knives 411, and the two wind knives 411 are spaced apart along the height direction of the second slide plate 410, and the two wind knives 411 are located between the first through hole 321 and the second through hole 421. When the laser 330 performs laser welding on the workpiece, the debris generated by the welding is easy to drift between the first through hole 321 and the second through hole 421, which is easy to affect the irradiation of the laser, thereby affecting the welding effect. At this time, the air path between the first through hole 321 and the second through hole 421 is continuously blown by the wind knife 411 to clear the debris between the first through hole 321 and the second through hole 421, so as to maintain the normal irradiation of the laser, thereby improving the effect of laser welding.

[0041] The implementation principle of the present application is as follows: when the workpiece needs laser welding, the first motor 511 drives the first screw rod 520 to rotate, and the first screw rod 520 is used to cooperate with the first screw hole thread, so that the first connecting block 530 drives the second slide plate 410 to slide relative to the slide rail 200, so that the pressure plate 420 descends to press the workpiece, thereby fixing the workpiece; the second motor 611 drives the second screw rod 620 to rotate, and the second screw rod 620 is used to cooperate with the second screw hole thread, so that the second connecting block 630 drives the first slide plate 310 to slide relative to the slide rail 200, so as to realize the lifting and lowering of the supporting plate 320, thereby changing the distance between the laser 330 and the workpiece, and realizing the adjustment of the welding focal length of the laser 330. At this time, the laser is emitted by the laser 330, and the laser passes through the first through hole 321 and the second through hole 421 in turn, so that the laser is irradiated to the workpiece, and the workpiece is laser welded. The present application sets a first space 700 so that the first screw rod 520 can pass through the first space 700 and be connected to the fixed component 400, thereby realizing that the first drive component 500 and the second drive component 600 are integrated on the same base plate 100 and are arranged side by side. The first motor 511 and the second motor 611 are located at the same end of the base plate 100, making the structure of the welding control mechanism more compact and standardized, solving the problem of the large space occupied by the welding control mechanism, and improving the compatibility and versatility of the welding control mechanism.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
