[0002] Laser welding is an efficient and precise welding method that uses a laser beam with a high energy density as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology.

[0003] For example, the Chinese patent publication number is CN115609146A, and the technical solution disclosed in this patent document is as follows: A self-purifying laser welding device includes a support frame and a purification box. Fixed rods are provided on both sides of the outer wall of the support frame, and a top plate is provided on the outer wall of the top of the fixed rods. A fan is provided on the outer wall of the top of the top plate, and a first conduit is provided between the output end of the fan and the inner wall of the top of the purification box. A dust suction plate is provided on the inner wall of the bottom of the support frame, and the dust suction plate is in a circular ring structure; when the fan is turned on, the circular ring-shaped dust suction plate can introduce the odor and dust generated during welding into the purification box through the first conduit and the second conduit, and the dust is effectively purified by a filtering mechanism. When the atomizing nozzle is turned on, the atomized water sprays upward, and the gas flows downward. When the two meet, the dust is sprayed and dust-settled. When the ozone generator is turned on, the odor can be effectively disinfected, improving the technical effect of the purification effect.

[0025] Embodiment 1: As Figures 1-7 shown, a self-purifying laser welding device includes a bottom plate 1. The bottom plate 1 is the foundation and support structure of the entire laser welding device. Its main function is to provide stable support and serve as an installation platform for other components. A support rod 2 is fixedly connected to the upper end of the bottom plate 1. The top of the support rod 2 is fixedly connected to a top plate 3. The support rod 2 connects the bottom plate 1 and the top plate 3, playing a role of bearing and supporting, so that the entire device remains vertical and stable. The support rod 2 also ensures the fixed relationship between the top plate 3 and the bottom plate 1, providing support for the welding and purification components 4. The top plate 3 is located at the top of the device, and its main function is to provide support for other components of the device to ensure the stability of the structure. A purification component 4 and a laser welding component 5 are arranged at the upper end of the bottom plate 1. The function of the purification component 4 is to effectively purify the smoke, dust and harmful gases generated during the welding process through a dust suction and filtering device. The laser welding component 5 is responsible for the actual laser welding operation and is the core part of the entire device to achieve the welding function. A welding table 6 is fixedly connected to the upper end of the bottom plate 1, and a mounting plate 9 is fixedly connected to the bottom of the top plate 3; The purification component 4 includes a U-shaped plate 41 which is fixed on the bottom plate 1 and plays a role in support and structural protection. The U-shaped plate 41 is fixedly connected to the upper end of the bottom plate 1. Inside the U-shaped plate 41, a motor 42 is fixedly connected. The output end of the motor 42 is fixedly connected to a transmission shaft 43. The outer wall of the transmission shaft 43 is slidably connected to the outer wall of a transmission cylinder 44. A rotating plate 45 is fixedly sleeved on the outer wall of the transmission cylinder 44. The upper end of the top plate 3 is fixedly connected to a blower 46. The function of the blower 46 is to generate a strong air flow, suck the waste gas generated during the welding process, and convey it to the purification box 410 through a dust suction hood 48 and a dust suction pipe 47. The input end of the blower 46 is fixedly connected to the dust suction pipe 47. The dust suction pipe 47 is fixedly connected to the rotating plate 45. The other end of the dust suction pipe 47 is fixedly connected to the dust suction hood 48. The dust suction pipe 47 and the dust suction hood 48 together form a waste gas absorption system, which sucks the smoke and harmful gases generated during the welding process into the system for purification. The output end of the blower 46 is fixedly connected to a delivery pipe 49. The other end of the delivery pipe 49 is fixedly connected to the purification box 410. The inhaled waste gas is conveyed to the purification box 410 through the delivery pipe 49 for treatment. Inside the purification box 410, there are materials such as filter screens and activated carbon, which are used to remove harmful components in the waste gas. A ratchet 411 is fixedly sleeved on the outer wall of the transmission shaft 43. The top of the U-shaped plate 41 is fixedly connected to a circular ring 412. An installation groove 413 is formed in the inner wall of the circular ring 412. Inside the installation groove 413, a ratchet pawl 414 is rotatably connected through a pin shaft. A spring A 415 is fixedly connected to the inner wall of the installation groove 413. The other end of the spring A 415 is fixedly connected to the ratchet pawl 414. A worm 416 is fixedly connected to the upper end of the circular ring 412. The outer wall of a mounting plate 9 is rotatably connected to a rotating shaft A 418. The end of the rotating shaft A 418 away from the mounting plate 9 is fixedly connected to a worm gear 417. The worm gear 417 meshes with the worm 416. A transmission wheel A 419 is fixedly sleeved on the outer wall of the rotating shaft A 418. A transmission belt 420 is wound around the outer wall of the transmission wheel A 419. The inner wall of the other side of the transmission belt 420 is drivingly connected to a transmission wheel B 421. The outer wall of the mounting plate 9 is rotatably connected to a rotating shaft B 422. The end of the rotating shaft B 422 away from the mounting plate 9 is fixedly connected to a connecting rod A 423. The other end of the connecting rod A 423 is rotatably connected to a connecting rod B 424 through a pin shaft. The other end of the connecting rod B 424 is rotatably connected to a connecting plate 425 through a pin shaft. The connecting plate 425 is fixedly sleeved on the outer wall of the transmission cylinder 44.

[0026] The purification component 4 further includes a clamping groove 426 which is formed in the inner wall of the transmission cylinder 44. A clamping block 427 is fixedly connected to the outer wall of the transmission shaft 43. The clamping block 427 is slidably connected inside the clamping groove 426. The cooperation of these two components ensures the stability of the internal structure of the device under specific circumstances. The clamping groove 426 is fixed in the inner wall of the transmission cylinder 44, and the clamping block 427 is fixed on the outer wall of the transmission shaft 43. Their cooperation ensures the operation accuracy of the transmission system.

[0027] The laser welding assembly 5 includes an electric telescopic rod 51. The electric telescopic rod 51 is fixedly connected to the upper end of the rotating plate 45. The output end of the electric telescopic rod 51 is fixedly connected with a connecting block 52. The bottom of the connecting block 52 is fixedly connected with a laser welding head 53.

[0028] A chute A54 is opened at the upper end of the rotating plate 45. The connecting block 52 is slidably connected inside the chute A54.

[0029] During use, when first adjusting the positions of the welding and the dust suction hood 48 as needed, first start the motor 42 to drive the transmission shaft 43 to rotate counterclockwise. When the transmission shaft 43 rotates counterclockwise, the ratchet wheel 411 fixedly sleeved on its outer part will also rotate counterclockwise. Furthermore, the ring 412 can be driven to rotate through the ratchet pawl 414 on its outer side. And the spring A415 will make the ratchet pawl 414 always approach the ratchet wheel 411. At this time, when the ring 412 rotates, the worm 416 at its upper end will be driven to rotate. Then the worm gear 417 meshed with its side can be driven to rotate. Furthermore, the rotating shaft A418 will rotate at any time, thus driving the transmission wheel A419 to rotate. Then, under the driving action of the transmission belt 420, the transmission wheel B421 will be driven to rotate. Furthermore, the rotating shaft B422 can be driven to rotate at any time. Then the connecting rod A423 will rotate around the rotating shaft B422. Furthermore, one end of the connecting rod B424 connected thereto will also rotate around the rotating shaft B422. Then the connecting plate 425 rotatably connected to the other end of the rotating shaft B422 through a pin shaft can move up and down. The connecting plate 425 will then drive the transmission cylinder 44 to slide on the outer wall of the transmission shaft 43. Furthermore, the rotating plate 45 fixedly sleeved on the outer wall of the transmission cylinder 44 will rise and fall accordingly. Thus, the laser welding assembly 5 and the bottoms of the dust suction pipe 47 and the dust suction hood 48 can be lifted and lowered. When the position of the laser welding assembly 5 is adjusted, the motor 42 can be driven to drive the transmission shaft 43 to rotate clockwise. At this time, the ratchet wheel 411 will also rotate clockwise. In this state, the ratchet wheel 411 will not drive the ring 412 to rotate through the ratchet pawl 414. And at this time, the transmission shaft 43 will drive the transmission cylinder 44 to rotate through the cooperation of the clamping block 427 on its outer wall and the clamping groove 426 on the inner wall of the transmission cylinder 44. Furthermore, the transmission cylinder 44 will drive the rotating plate 45 to rotate until the laser welding assembly 5 is rotated to the upper end of the welding point. This move can ensure that the dust suction hood 48 is always located on the side of the welding position. When it is necessary to adjust the horizontal position of the laser welding head 53 in the laser welding assembly 5, start the electric telescopic rod 51 to drive the connecting block 52 to slide inside the chute A54. Furthermore, the position of the laser welding head 53 at the bottom of the connecting block 52 can be driven. Then welding can be carried out through the laser welding head 53. When welding, start the blower 46. Then the dust and odor generated during the welding process can be adsorbed through the dust suction hood 48 and the dust suction pipe 47 and conveyed to the inside of the purification box 410 through the conveying pipe 49.

[0030] Embodiment 2: As Figures 1-9 shown, a pushing component 7 is arranged at the upper end of the bottom plate 1. The function of the pushing component 7 is to push the workpiece that has been welded off the welding table 6 to prevent the workpiece from hindering subsequent welding operations. The pushing component 7 includes a connecting rod A71, the connecting rod A71 is fixedly connected to the side surface of the connecting plate 425, the other end of the connecting rod A71 is fixedly connected to a toothed plate A72, a transmission gear 73 is rotatably connected to the outer wall of the mounting plate 9, toothed plates B74 are engaged with the upper and lower sides of the transmission gear 73, a connecting rod B75 is fixedly connected to the outer wall of the toothed plate B74, the other end of the connecting rod B75 is fixedly connected to a pushing plate 76, and the function of the pushing plate 76 is to push the workpiece completed on the welding table 6 off to ensure the smooth progress of subsequent welding work.

[0031] A chute B79 is formed in the outer wall of the mounting plate 9, the connecting rod A71 is slidably connected to the chute B79, a chute C77 is formed in the outer wall of the toothed plate B74, and a guide plate 78 is fixedly connected to the outer wall of the mounting plate 9, and the guide plate 78 is slidably connected inside the chute C77.

[0032] During use, when the connecting plate 425 in the purification component 4 rises, this signal indicates that the welding has been completed. During the welding process, the rise of the connecting plate 425 means that the welding process has been completed and the entire system is about to enter the subsequent workpiece processing stage. Then, as the connecting plate 425 rises, the laser welding head 53 will also rise accordingly. This change is usually a synchronous reaction with the completion of the welding work. The rise of the laser welding head 53 is not only a physical lift but also marks the end of the laser welding process. Usually, the laser welding head 53 on the welding table 6 will automatically rise at the end of welding to reduce contact with the workpiece, avoid overheating or unnecessary interference. At the same time, the rise of the connecting plate 425 will also push the connecting rod A71 to slide in the chute B79. Through its sliding in the chute B79, the connecting rod A71 will drive the toothed plate A72 to rise. The rise of the toothed plate A72 triggers an important mechanical transmission process, which further transmits the kinetic energy. When the toothed plate A72 rises, it meshes with the transmission gear 73, causing the transmission gear 73 to rotate. The rotation of the transmission gear 73 will generate corresponding mechanical movements, usually driving other components to work through gear meshing. In this process, the rise of the toothed plate A72 and the rotation of the transmission gear 73 will cause the toothed plates B74 meshing with the upper and lower sides of the transmission gear 73 to move outward respectively. The outward movement of the toothed plate B74 is very crucial. It slides on the outer wall of the guide plate 78 through the chute C77. The design of the chute C77 is usually to ensure the stability of the toothed plate B74 during movement and avoid jamming or damage to the system caused by friction or asymmetric forces. When the toothed plate B74 moves outward, it is connected to the connecting rod B75, which will drive the push plate 76 to move outward through the connecting rod B75. The function of the push plate 76 is to push the welded workpiece on the welding table 6 off. The design of this part usually involves fine pressure and distance control. The movement of the push plate 76 should not be too violent to avoid damaging the welded workpiece. At the same time, the movement of the push plate 76 should also be ensured to be smooth so as to smoothly push the workpiece away from the welding table 6 and complete the subsequent operation process.

[0033] Example 3: As Figures 1-10As shown, positioning components 8 are provided at the bottom and sides of the welding table 6. The positioning components 8 ensure that the workpiece is always in the correct position during the welding process, so as to improve the welding accuracy and stability. The positioning components 8 include grooves 81 which are opened on both sides of the welding table 6. The inner wall of the groove 81 is rotatably connected to a clamping jaw 82 by a pin shaft. A receiving groove 83 is opened at the bottom of the clamping jaw 82. A fixing block 84 is fixedly connected to the inner wall of the receiving groove 83. A roller 85 is rotatably connected to the inner side of the fixing block 84. The roller 85 ensures that the clamping jaw 82 can rotate smoothly and releases the clamping of the workpiece when necessary, facilitating the subsequent material pushing operation. A hydraulic rod A86 is fixedly connected to the outer wall of the connecting rod B75. A hydraulic chamber 87 is fixedly connected to the upper end of the bottom plate 1. The hydraulic rod A86 is slidably connected inside one port of the hydraulic chamber 87. A hydraulic rod B88 is slidably connected inside the other port of the hydraulic chamber 87. The other end of the hydraulic rod B88 is fixedly connected to a pushing block 89. A fixing rod 816 is fixedly connected to the upper end of the bottom plate 1. A moving block 810 is slidably connected to the outside of the fixing rod 816. A conical block 811 is fixedly connected to the upper end of the moving block 810. A baffle 812 is fixedly connected to the upper end of the moving block 810. A spring B813 is movably sleeved on the outer wall of the fixing rod 816. The two ends of the spring B813 are respectively fixedly connected to the welding table 6 and the moving block 810.

[0034] A spring C814 is hinged to the upper end of the bottom plate 1 through a hinge block. The other end of the spring C814 is fixedly connected to the clamping jaw 82. The spring C814 is used to control the opening and closing of the clamping jaw 82, ensuring that the clamping jaw 82 can flexibly clamp the workpiece when needed, and avoiding excessive or insufficient clamping force.

[0035] During use, when the push plate 76 in the material pushing assembly 7 is pushing the material, the connecting rod B75 will drive the hydraulic rod A86 to slide inside the hydraulic chamber 87. Then, the hydraulic rod B88 inside the other port of the hydraulic chamber 87 will move outward, thereby driving the push block 89 to move towards the middle of the bottom plate 1, causing the push block 89 to move away from the moving block 810. At this time, the moving block 810 loses its restraint, and then under the action of the spring B813, the moving block 810 will slide downward along the outer wall of the fixed rod 816. Then, the conical block 811 and the baffle 812 at the upper end of the moving block 810 will also move downward. When the conical block 811 descends, after the roller 85 loses its restraint, with the cooperation of the spring C814, the clamping jaw 82 will rotate around its hinge point with the groove 81, causing the clamping jaw 82 to rotate outward, thereby releasing the positioning of the workpiece on the upper end of the welding table 6. At the same time, the baffle 812 also releases the blockage of the workpiece, thus ensuring the smooth progress of the material pushing process. After the material pushing is completed, the connecting rod B75 will drive the hydraulic rod A86 to reset, and at the same time, place the newly to-be-processed workpiece on the upper end of the welding table 6. When the hydraulic rod A86 resets, the hydraulic rod B88 will drive the push block 89 to move towards the side of the bottom plate 1. Then, the push block 89 will push the moving block 810 to move upward. When the moving block 810 rises, the baffle 812 and the conical block 811 will also rise accordingly. Since the contact surface between the roller 85 and the conical block 811 changes from narrow to wide, the clamping jaw 82 can be made to rotate inward, thereby positioning both sides of the workpiece.
