With the rapid development of the new energy vehicle industry, extremely stringent requirements have been put forward for the precision, efficiency, and adaptability of component welding. There is a need to develop a welding device for new energy vehicle production to perform welding operations on new energy vehicles.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 - 5 , a welding device for new energy vehicle production, including a frame 1, a first adjustment motor 2 is installed on the top of the frame 1, and a docking assembly 3 is provided at the output end of the first adjustment motor 2. The docking assembly 3 includes a first driving rod 301, and a clamping shaft 302 is installed at the lower end of the first driving rod 301. A total docking ring 303 is sleeved outside the clamping shaft 302, and an upper docking ring 304 and a first connecting sleeve rod 305 are installed at the upper end of the total docking ring 303. A lower docking ring 306 and a second connecting sleeve rod 307 are installed at the lower end of the total docking ring 303. A pneumatic telescopic rod 309 is provided on one side of the total docking ring 303, and a cross bar 310 is installed at the output end of the pneumatic telescopic rod 309. A clamping ring 313 is installed at one end of the cross bar 310.

[0025] In this embodiment, the frame 1 is installed at the required position through a suitable installation method, and the welding device uses the frame 1 as the basic support structure, providing a stable installation platform for the entire device, ensuring that each component will not be displaced due to vibration or external force interference during the welding process, affecting the welding accuracy. The first adjustment motor 2 is installed on the top of the frame 1, and its main function is to provide power for the docking component 3. It is externally connected to a power supply, a controller, and a receiver. The first driving rod 301 is a power transmission component of the docking component. Its upper end is connected to the output end of the first adjustment motor 2, and a clamping shaft 302 is installed at the lower end. The clamping shaft 302 not only plays a role in supporting the total docking ring 303, but also can drive the total docking ring 303 to generate a corresponding rotational movement under the drive of the first driving rod 301, so as to better dock with the upper docking ring 304 and the lower docking ring 306, thereby respectively driving the first connecting sleeve rod 305 and the second connecting sleeve rod 307 to generate corresponding rotational movements. The pneumatic telescopic rod 309 is externally connected to a gas source, a controller, and a receiver, facilitating better control of the operation timing of the pneumatic telescopic rod 309. The pneumatic telescopic rod 309 drives the cross bar 310 to move up and down, thereby controlling the up and down movement of the clamping ring 313, facilitating driving the total docking ring 303 docked with the clamping ring 313 to move up and down to achieve the docking operation, and the clamping ring 313 and the total docking ring 303 are matched, and when the total docking ring 303 rotates, the clamping ring 313 does not affect its rotation.

[0026] Specifically, a first mounting plate 308 is installed at the lower end of the frame 1. A through rod 311 is installed at the upper end of the cross bar 310, and a spring 312 is sleeved outside the through rod 311. The clamping shaft 302 is engaged and slidably connected with the total docking ring 303. The total docking ring 303 has a structure with convexities at both the upper and lower ends, which are respectively matched with the upper docking ring 304 and the lower docking ring 306. The clamping ring 313 is matched with the total docking ring 303. The through rod 311 passes through the first mounting plate 308 and extends to its outside. A sliding rod 314 is provided at the lower end of the second connecting sleeve rod 307 and is engaged and slidably connected with it.

[0027] In this embodiment, the first mounting plate 308 is composed of two sets of horizontal plates and one set of vertical plates. The two sets of horizontal plates are respectively mounted together with the first connecting sleeve rod 305 and the second connecting sleeve rod 307 through bearings, which play a certain supporting role without affecting the operation of the first connecting sleeve rod 305 and the second connecting sleeve rod 307. At the same time, the top end of one set of vertical plates is mounted on the frame 1, which plays a role in supporting and connecting the first mounting plate 308. When the pneumatic telescopic rod 309 drives the cross bar 310 to move, the through rod 311 will move accordingly. The spring 312 plays a role in buffering and adjusting here. The clamping shaft 302 is engaged and slidably connected with the total docking ring 303. This connection method enables the total docking ring 303 to not only rotate under the drive of the clamping shaft 302, but also slide within a certain range along the axial direction on the clamping shaft. The total docking ring 303 has a structure with protrusions at both the upper and lower ends, which are respectively matched with the upper docking ring 304 and the lower docking ring 306. The protrusion structure and the docking ring are tightly connected by means including but not limited to clamping and nesting. When the total docking ring 303 moves, it drives the upper docking ring 304 and the lower docking ring 306 to move synchronously. When the pneumatic telescopic rod 309 drives the cross bar 310 and the clamping ring 313 to move to a suitable position, it drives the total docking ring 303 to move to a suitable position for use. The clamping ring 313 is a semi-circular structure and is used by being stuck in the concave ring opened in the middle position of the total docking ring 303. A sliding rod 314 is provided at the lower end of the second connecting sleeve rod 307 and is engaged and slidably connected therewith. The sliding rod 314 can slide along the axial direction within the second connecting sleeve rod 307 and rotate along with the second connecting sleeve rod 307 when the second connecting sleeve rod 307 rotates, which is convenient for cooperating with the lifting assembly 4 for use.

[0028] Specifically, a lifting assembly 4 is provided on one side of the docking assembly 3, and the lifting assembly 4 includes a first pulley assembly 401. An installation frame 402 is installed at the lower end of the frame 1. A limiting tube 403 is provided at the lower end of the installation frame 402. The lower end of the first pulley assembly 401 is connected with a lead screw 404, and a moving block 405 is sleeved outside the lead screw 404. An expansion rod 406 is installed at the lower end of the moving block 405.

[0029] In this embodiment, the first pulley assembly 401 serves as the starting component for power transmission of the lifting assembly. The first pulley assembly 401 generally consists of a driving pulley, a driven pulley, and a transmission belt. The driving pulley is connected to the first connecting sleeve rod 305. When the total docking ring 303 in the docking assembly 3 docks with the docking ring 304, it drives the first pulley assembly 401 to rotate, and drives the driven pulley to rotate synchronously through the transmission belt, so as to stably transmit the power to the lead screw 404. An installation frame 402 is installed at the lower end of the frame 1, providing an installation and support foundation for the entire lifting assembly 4. The first pulley assembly 401, the lead screw 404 and other components are integrated together and firmly connected to the frame 1 to ensure that the entire assembly will not be displaced or shaken during the lifting operation. A limiting tube 403 is provided at the lower end of the installation frame 402, which mainly plays a role in limiting and guiding the movement of the moving block 405, so that the moving block 405 makes a linear up and down movement driven by the lead screw 404, so as to realize the linear up and down movement of the telescopic rod 406.

[0030] Specifically, one end of the first pulley assembly 401 is sleeved on the outside of the first connecting sleeve rod 305. The lead screw 404 matches the moving block 405, and the moving block 405 is slidably arranged in the limiting tube 403. The telescopic rod 406 passes through the limiting tube 403 and extends to its outside, and the telescopic rod 406 is detachably connected to the second mounting plate 601.

[0031] In this embodiment, the other end of the first pulley assembly 401 is connected to the lead screw 404 to realize the synchronous operation of the first connecting sleeve rod 305 and the lead screw 404. Using the principle of lead screw transmission, the rotational motion of the lead screw 404 is converted into the linear motion of the moving block 405. This conversion can achieve high-precision position control. By accurately controlling the number of rotations and direction of the lead screw 404, the position of the moving block 405 on the lead screw can be accurately adjusted, so as to accurately control the height of the telescopic rod 406 and related equipment installed at the lower end of the moving block 405. The limiting tube 403 plays a role of guiding and stabilizing, restricting the movement track of the moving block 405 so that it can only make a linear motion along the axial direction, avoiding the deviation or shaking of the moving block 405 during the movement process, ensuring the stability of the lifting process, and the telescopic rod 406 transmits the linear motion of the moving block 405 to the second mounting plate 601, so as to realize the linear motion of the second mounting plate 601, facilitating the adjustment of the vertical position of the related equipment installed at the lower end of the second mounting plate 601.

[0032] Please refer to Figures 6 - 7, a welding device for new energy vehicle production. A position adjustment component 6 is installed at the lower end of the docking component 3. The position adjustment component 6 includes a second mounting plate 601, and a first sliding groove 602 is opened at the lower end of the second mounting plate 601. A first sliding block 603 is arranged in the first sliding groove 602, and a moving plate 604 is installed at the lower end of the first sliding block 603. A second sliding block 605 is arranged at the upper end of the moving plate 604, and second belt pulleys 609 are installed at the four corners of the moving plate 604. A connecting rod 606 is installed at the lower end of the second mounting plate 601, and a first belt pulley 607 is installed at the bottom of the connecting rod 606. A long rod 612 is arranged at the upper end of the second sliding block 605, and third belt pulleys 610 are connected to both ends of the long rod 612 through connecting blocks 611. A belt 608 is wound around the outer sides of the first belt pulley 607, the second belt pulley 609, and the third belt pulley 610.

[0033] In this embodiment, the docking component 3 is used to drive the operation of the position adjustment component 6, so as to flexibly adjust the positions of the X and Y axes of the laser welding head 812, ensure the accuracy of the welding position, thereby improving the welding quality, reducing welding deviations and defects, and is especially suitable for welding small parts or precision components with high welding precision requirements. According to different welding tasks and workpiece shapes, the position of the laser welding head 812 can be quickly adjusted to adapt to various complex welding paths and curves, improving the welding adaptability of the equipment to different types of workpieces and expanding the application range of the equipment. When the total docking ring 303 moves to dock with the lower docking ring 306, the second connecting sleeve rod 307 and the sliding rod 314 rotate, and the second connecting sleeve rod 307 and the sliding rod 314 are engaged and slidably connected. The second mounting plate 601, as the basic mounting component of the position adjustment component 6, provides mounting positions and support for other components. The moving plate 604 uses the first sliding block 603 and the first sliding groove 602 to make the moving plate 604 perform horizontal position adjustment at the lower end of the second mounting plate 601. The moving plate 604 is used to install other related components, such as the second sliding block 605 and the second belt pulley 609, etc. The second sliding block 605 is connected to the long rod 612 and can slide on the moving plate 604, further providing the freedom of position adjustment for the long rod 612 and the third belt pulleys 610 connected to both ends thereof, making the position adjustment of the welding device in different directions more flexible. The second belt pulley 609, the first belt pulley 607, the third belt pulley 610, and the belt 608 form a belt drive system. The first belt pulley 607 is installed at the bottom of the connecting rod 606, the second belt pulley 609 is installed at the four corners of the moving plate 604, and the third belt pulley 610 is connected to the long rod 612 through the connecting block 611. When the second belt pulley 609 and the auxiliary first belt pulley 505 rotate, the other belt pulleys are driven to rotate through the belt 608, thereby realizing power transmission and motion conversion. This drive system can make the movements of components such as the moving plate 604 and the long rod 612 be interrelated and coordinated to achieve more complex position adjustment actions.

[0034] Specifically, the lower end of the sliding rod 314 is detachably connected to the connecting rod 606. There are two sets of third belt pulleys 610, which are symmetrically arranged at both ends of the long rod 612. The winding shape of the belt 608 is a cross-shaped structure. The first slider 603 is slidably arranged in the first chute 602. The long rod 612 is slidably connected to the moving plate 604 through the second slider 605. An installation rod 613 is installed at the lower end of the long rod 612.

[0035] In this embodiment, a relatively independent and connectable relationship can be achieved between the docking component 3 and the position adjustment component 6. The sliding rod 314 can transfer part of the movement or force of the docking component 3 to the position adjustment component 6, enabling the two components to work together. When the sliding rod 314 rotates, it drives the connecting rod 606 to rotate. The symmetrically arranged third belt pulleys 610 can ensure the uniform distribution of force during the transmission of the belt 608, making the force received by the long rod 612 more balanced and avoiding the inclination or distortion of the long rod 612 caused by uneven force, thereby ensuring the stability and accuracy of the entire position adjustment component 6. The cross-shaped winding structure enables the belt 608 to connect the first belt pulley 607, the second belt pulley 609, the third belt pulley 610, and the auxiliary first belt pulley 505 at the same time, and realizes the power transmission in different directions. This structure can effectively couple the movements of each belt pulley. Through different rotational speeds and steering controls, the horizontal movement of the moving plate 604 and the longitudinal movement of the long rod 612 are achieved. A chute is provided at the position of the moving plate 604 corresponding to the movement of the second slider 605. The transmission and adjustment of the position of the installation rod 613 are realized through the position movement of the long rod 612.

[0036] Specifically, an auxiliary drive component 5 is provided at the symmetric position of the first adjustment motor 2 on the frame 1. The auxiliary drive component 5 includes a second adjustment motor 501. The output end of the second adjustment motor 501 is installed with a first clamping rod 502, and a second clamping rod 503 that is fitted and slidably connected to the lower end of the first clamping rod 502 is installed. A second drive rod 504 is provided at the bottom of the second clamping rod 503, and an auxiliary first belt pulley 505 is provided at the symmetric position of the bottom of the second drive rod 504 and the first belt pulley 607.

[0037] In this embodiment, the frame 1 provides a certain supporting effect for the auxiliary driving component 5. The auxiliary driving component 5 is externally connected to a power supply, a controller, and a receiver to ensure the normal operation of the device. The auxiliary driving component 5 and the first adjusting motor 2 act on the auxiliary first pulley 505 and the first pulley 607 respectively, for controlling the rotation speed and rotation direction of the auxiliary first pulley 505 and the first pulley 607. The first clamping rod 502 and the second clamping rod 503 are engaged and slidably connected to facilitate length adjustment, and are convenient for cooperating with the lifting component 4 for use, controlling three forms of operation of the first pulley 607 and the auxiliary first pulley 505, so as to realize the position adjustment of the laser welding head 812 in the X and Y axis directions.

[0038] Please refer to Figures 8 - 9 , a welding device for new energy vehicle production. An auxiliary mounting component 7 is mounted at the lower end of the mounting rod 613. The auxiliary mounting component 7 includes an L-shaped mounting plate 701, and a third adjusting motor 702 is mounted at the upper end of the L-shaped mounting plate 701. The output end of the third adjusting motor 702 is connected to a set of docking components 3, and a lifting component 4 is arranged on one side of the docking components 3. Angle adjusting components 8 are mounted at the lower ends of the docking components 3 and the lifting component 4.

[0039] In this embodiment, the auxiliary mounting component 7 is mounted at the lower end of the mounting rod 613 to transfer the movement of the mounting rod 613 to the auxiliary mounting component 7, facilitating the position adjustment of the auxiliary mounting component 7. The L-shaped mounting plate 701 provides a supporting effect for a set of docking components 3 and a set of lifting components 4, which has the same structure as the above-mentioned docking components 3 and lifting components 4. The third adjusting motor 702 provides driving force for the docking components 3 and the lifting components 4, and the third adjusting motor 702 is externally connected to a power supply, a controller, and a receiver to ensure the independent operation of each device. The bottoms of the docking components 3 and the lifting components 4 both act on the angle adjusting component 8, facilitating the adjustment of the height of the angle adjusting component 8.

[0040] Specifically, the mounting rod 613 is fixedly connected to the L-shaped mounting plate 701, and the output end of the third adjusting motor 702 is detachably connected to the docking component 3.

[0041] In this embodiment, the position of the L-shaped mounting plate 701 is adjusted by using the position adjustment of the mounting rod 613, so as to adjust the position of the laser welding head 812. The output end of the third adjusting motor 702 is connected to the first driving rod 301 in the docking component 3, for driving the first driving rod 301 and the clamping shaft 302 to operate. The third adjusting motor 702 is externally connected to a power supply, a controller, and a receiver to ensure the independent operation of each device.

[0042] Specifically, the angle adjustment component 8 includes a mounting base 801, and a second pulley set 802 is provided at the lower end of the mounting base 801. A first gear 803 is provided at the lower end of one end of the second pulley set 802. A second gear 804 meshing with the first gear 803 is installed on one side of the first gear 803. An internal gear ring 805 is sleeved outside the second gear 804. Another set of docking components 3 is provided at the lower end of the internal gear ring 805. An L-shaped connecting rod 806 is installed at the lower end of the second gear 804. A vertical rod 807 is fixedly installed at the lower end of the L-shaped connecting rod 806. A rotating seat 808 is installed at the lower end of the vertical rod 807. A bracket 809 is installed on one side of the rotating seat 808. A bevel gear set 810 is installed on one side of the bracket 809. An L-shaped mounting rod 811 is installed at one end of the bevel gear set 810. A laser welding head 812 is installed at one end of the L-shaped mounting rod 811.

[0043] In this embodiment, the mounting base 801 provides a foundation for the installation and support of the angle adjustment component 8, and is firmly connected to the lower ends of the docking component 3 and the lifting component 4 to ensure stability during the working process. The second pulley set 802 is a key component for power transmission, usually composed of a driving pulley, a driven pulley, and a transmission belt, and is connected to the slide rod 314 in the docking component 3 to transmit power to the first gear 803. The first gear 803 starts to rotate under the drive of the second pulley set 802. Since the first gear 803 meshes with the second gear 804, the rotational movement of the first gear 803 can be accurately transmitted to the second gear 804 to achieve power steering. The internal gear ring 805 is fixedly arranged to provide a certain limiting effect for the operation of the second gear 804, so that the second gear 804 makes a circular motion around the center position of the first gear 803. The L-shaped connecting rod 806 installed at the lower end of the second gear 804 plays a role in connecting and transmitting motion. The bracket 809 provides installation support for the bevel gear set 810 to ensure its stability during the working process. And a set of docking components 3 is installed at the lower end of the first gear 803. The first connecting sleeve rod 305 in the docking component 3 is connected to the first gear 803, and the second connecting sleeve rod 307 in the docking component 3 is connected to the bevel gear set 810. By using the docking component 3, the angle of the laser welding head 812 can be adjusted in all directions.

[0044] Specifically, the second gear 804 meshes with the internal gear ring 805. One end of the second pulley set 802 is connected to a set of slide rods 314. A set of second connecting sleeve rods 307 penetrate through the L-shaped connecting rod 806 and extend to the outside to be detachably connected to the bevel gear set 810.

[0045] In this embodiment, the rotation of the slide bar 314 is transmitted to a set of docking components 3 installed on one side of the angle adjustment component 8 by means of the second pulley set 802. The docking component 3 has a unique control function and can independently control the rotation of the rotating seat 808 or the bevel gear set 810. When the docking component 3 controls the rotation of the rotating seat 808, the angle adjustment of the laser welding head 812 in one plane can be achieved; when controlling the rotation of the bevel gear set 810, the angle change of the laser welding head 812 in another plane can be achieved, so as to realize the precise angle adjustment of the laser welding head 812 in two planes in an all-round and flexible manner, tightly connecting the second connecting sleeve rod 307 with the bevel gear set 810, creating favorable conditions for the smooth transmission of power from the docking component 3 to the bevel gear set 810, and further ensuring that the bevel gear set 810 can drive the L-shaped mounting rod 811 and the laser welding head 812 to make precise angle adjustments according to the control instructions of the docking component 3, greatly improving the flexibility and adaptability of the welding device and meeting the diverse welding angle requirements of various parts of new energy vehicles. The bevel gear set 810 is composed of two meshing bevel gears, one group is connected to the second connecting sleeve rod 307, and one group is installed on one side of the bracket 809. To sum up, position sensors are set at the key moving parts of the second mounting plate 601, the long rod 612 and the mounting seat 801 to monitor the position information of the laser welding head 812 in the X, Y, and Z axes in all directions in real time and feed it back to the control system, so that the control system can make precise adjustments according to the preset positions. Angle sensors are installed at the parts related to angle adjustment of the rotating seat 808 and the L-shaped mounting rod 811 to accurately measure the angle changes of the laser welding head 812 in the horizontal and vertical planes and feed the data back to the control system, enabling the control system to accurately control the laser welding head 812 to reach the required welding angle. Contact sensors are set at the docking parts of the total docking ring 303 with the upper docking ring 304 and the lower docking ring 306. When the two are docked, the sensors can detect the contact signal in time and feed it back to the control system, and the control system controls the subsequent actions of related components accordingly, such as controlling the motor to rotate to achieve further position or angle adjustment. Moreover, a vision sensor, such as an industrial camera, is installed on the welding device. Before welding, the vision system can scan the welding parts, compare the position and shape of the actual parts with the standard model pre-stored in the system through image recognition technology. If a deviation is found, the system can quickly calculate the position and angle data that the laser welding head needs to adjust and feed this information back to the control system, thus realizing the automatic adjustment of the laser welding head.

[0046] During use, when it is necessary to adjust the vertical position of the laser welding head 812, first start the pneumatic telescopic rod 309. The pneumatic telescopic rod 309 drives the cross bar 310 to move. The movement of the cross bar 310 drives the through rod 311, causing the spring 312 sleeved on its outer side to undergo elastic deformation. At the same time, the snap ring 313 installed at one end of the cross bar 310 moves accordingly, thereby driving the total docking ring 303 to move. When the total docking ring 303 moves to successfully dock with the upper docking ring 304, to achieve subsequent vertical position adjustment, start the first adjustment motor 2. The first adjustment motor 2 drives the first drive rod 301 and the clamping shaft 302 to rotate. The rotation of the clamping shaft 302 drives the total docking ring 303 and the upper docking ring 304 to rotate synchronously, thereby driving the first connecting sleeve rod 305 to rotate. The rotation of the first connecting sleeve rod 305 drives the first pulley assembly 401 to operate. The first pulley assembly 401 drives the lead screw 404 to rotate. Since the lead screw 404 and the moving block 405 are in threaded cooperation, the rotation of the lead screw 404 drives the moving block 405 to slide in the limit tube 403. The movement of the moving block 405 drives the telescopic rod 406 to move. Since the telescopic rod 406 is connected to the second mounting plate 601, the second mounting plate 601 is driven to move up and down, realizing the adjustment of the vertical position of the laser welding head 812; When it is necessary to adjust the position of the laser welding head 812 in the X and Y axis directions, the pneumatic telescopic rod 309 is started. The pneumatic telescopic rod 309 drives the cross bar 310 to move. The cross bar 310 drives the snap ring 313 to move. The through rod 311 moves, causing the spring 312 to undergo elastic deformation. The movement of the snap ring 313 drives the total docking ring 303 to move. When the total docking ring 303 moves to dock with the lower docking ring 306, under the action of friction, the total docking ring 303 rotates to drive the lower docking ring 306 and the second connecting sleeve rod 307 connected thereto to rotate. The rotation of the second connecting sleeve rod 307 drives the slide rod 314 to operate. The slide rod 314 drives the connecting rod 606 to rotate. The rotation of the connecting rod 606 drives the first pulley 607 to rotate. At the same time, the second adjustment motor 501 in the auxiliary drive assembly 5 is started. The second adjustment motor 501 drives the first clamping rod 502 to rotate. The first clamping rod 502 drives the second clamping rod 503 that is engaged and slidably connected thereto to rotate. The rotation of the second clamping rod 503 drives the second drive rod 504 to rotate. The rotation of the second drive rod 504 drives the auxiliary first pulley 505 to operate. When the first pulley 607 and the auxiliary first pulley 505 are controlled to rotate in the same direction, the belt 608 operates accordingly. Since the belt 608 is wound around the outer sides of the first pulley 607, the second pulley 609, the third pulley 610, and the auxiliary first pulley 505, the operation of the belt 608 drives the long rod 612 to move in the X-axis direction; when the first pulley 607 and the auxiliary first pulley 505 are controlled to rotate in the opposite direction, the belt 608 operates, causing the long rod 612 to move in the Y-axis direction; when the first pulley 607 and the auxiliary first pulley 505 are controlled to operate at different speeds, the long rod 612 will move obliquely. The movement of the long rod 612 drives the mounting rod 613 to move. The movement of the mounting rod 613 drives the auxiliary mounting assembly 7 and the docking assembly 3 and the lifting assembly 4 connected thereto to move, so that the angle adjustment assembly 8 moves to a suitable position, thereby realizing the position adjustment of the laser welding head 812 in the X and Y axis directions. After the X and Y axis position adjustments are completed, to further accurately adjust the vertical position of the laser welding head 812, the docking assembly 3 connected to the auxiliary mounting assembly 7 is controlled to move the total docking ring 303 to dock with the upper docking ring 304. Under the action of friction, it drives the first connecting sleeve rod 305 to rotate. The rotation of the first connecting sleeve rod 305 drives the first pulley assembly 401 to operate, realizing the secondary precise adjustment of the vertical position; When it is necessary to adjust the angle of the laser welding head 812, start the third adjustment motor 702. The third adjustment motor 702 drives the first drive rod 301 and the clamping shaft 302 to operate. The rotation of the clamping shaft 302 drives the total docking ring 303 to rotate. At the same time, control the pneumatic telescopic rod 309 to move the total docking ring 303 to dock with the lower docking ring 306. Under the action of friction, it drives the second connecting sleeve rod 307 to rotate. The rotation of the second connecting sleeve rod 307 further drives the slide rod 314 to operate. The rotation of the slide rod 314 drives the second pulley group 802 to rotate. The rotation of the second pulley group 802 in turn causes the first drive rod 301 and the clamping shaft 302 connected to it to rotate. At the same time, control the total docking ring 303 in a set of docking components 3 provided by the angle adjustment component 8 to move to dock with the upper docking ring 304. Under the action of friction, it drives the first connecting sleeve rod 305 to rotate. The rotation of the first connecting sleeve rod 305 drives the first gear 803 to rotate. Since the first gear 803 meshes with the second gear 804, the rotation of the first gear 803 drives the second gear 804 to perform a circular motion. The circular motion of the second gear 804 drives the L-shaped connecting rod 806 to rotate. The rotation of the L-shaped connecting rod 806 drives the vertical rod 807 to rotate. The rotation of the vertical rod 807 drives the rotating seat 808 to rotate, thereby driving the bracket 809 to rotate. The rotation of the bracket 809 drives the bevel gear set 810, the L-shaped mounting rod 811 and the laser welding head 812 to rotate. Through the coordinated rotation of the above series of components, the angle adjustment of the laser welding head 812 in the horizontal plane is successfully achieved. Similarly, when the total docking ring 303 in a set of docking components 3 provided by the angle adjustment component 8 is controlled to move to dock with the lower docking ring 306, under the action of friction, it drives the second connecting sleeve rod 307 to rotate. The rotation of the second connecting sleeve rod 307 drives the bevel gear set 810 to operate. The special transmission structure of the bevel gear set 810 causes the L-shaped mounting rod 811 to rotate, thereby realizing the angle adjustment of the laser welding head 812 in the vertical plane.
