[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] See also Figures 1 to 7 As shown, a laser welding machine for metal accessories includes a base plate 1, wherein two first grooves 11 and a second groove 12 are provided on the top of the base plate 1, and a connecting plate 251 is slidably installed on the inner surface of the first groove 11, and a top plate 2 is fixedly installed on the top of the base plate 1, and a connecting column 33 is slidably installed on the bottom of the top plate 2, and the bottom of the connecting column 33 is rotatably connected to a transverse plate 41, and a laser welder 42 is fixedly installed on the bottom of the transverse plate 41; it also includes a heat dissipation mechanism for dissipating heat from the welded metal; the heat dissipation mechanism includes a purification box 46, which is fixedly installed on the bottom of the transverse plate 41, and a filter plate 462 and activated carbon 463 are fixedly installed in the inner cavity of the purification box 46, and two suction pipes 461 are fixedly connected to the outer surface of the purification box 46, a fan 45 is fixedly installed on one side of the purification box 46, and an air outlet pipe 451 is fixedly connected on one side of the fan 45, and the air outlet pipe 451 is fixedly installed on the bottom of the transverse plate 41.

[0025] After the metal parts are welded, they will generate high temperatures due to welding. At this time, workers cannot move the metal parts, which affects the welding efficiency.

[0026] When the present invention is in use, the metal parts to be welded are first placed on the top of the base plate 1, and then the two connecting plates 251 are brought close to each other to clamp the metal parts, and then the cross plate 41 is moved by the connecting column 33, and the cross plate 41 further carries the laser welder 42 to the top of the position where the metal parts need to be welded to weld the metal parts. Smoke is generated during welding, and the inner cavity of the purification box 46 is placed in a negative pressure state through the fan 45. At this time, the external air can be sucked into the inner cavity of the purification box 46 through the suction pipe 461. In this process, the smoke generated by welding will also enter the inner cavity of the purification box 46, and the particulate matter in the smoke can be filtered through the filter plate 462, and the harmful gases in the smoke can be absorbed by the activated carbon 463. Then the purified smoke is discharged through the outlet pipe 451. When in use, after the metal parts are welded, they will be moved to the other side of the top of the base plate 1, that is, the bottom of the outlet pipe 451. At this time, blowing air to the welded metal parts through the outlet pipe 451 can accelerate the cooling of the metal parts.

[0027] Further, such as Figure 2 and Figure 3 As shown, a mounting bracket 21 is fixedly mounted on the top of the top plate 2, a first electric telescopic rod 22 is fixedly mounted on the bottom of the mounting bracket 21, an output end of the first electric telescopic rod 22 is fixedly connected to a connecting block 221, and one side of the connecting block 221 is rotatably connected to a bidirectional threaded rod 222; A first motor 223 is fixedly mounted on one side of the connecting block 221 , and a pulley 224 is fixedly connected to the output shaft of the first motor 223 and the outer surface of the bidirectional threaded rod 222 , and the two pulleys 224 are driven by a belt 225 ; The outer surface of the bidirectional threaded rod 222 is threadedly connected to two slides 23, and a third groove 231 is formed on one side of the slide 23. A limit rod 24 is slidably installed on the inner surface of the third groove 231. The limit rod 24 is fixedly installed on one side of the top plate 2; A second motor 25 is fixedly installed on one side of the skateboard 23, and the output shaft of the second motor 25 is fixedly connected to the connecting plate 251. A second electric telescopic rod 252 is fixedly connected to the bottom of the connecting plate 251, and a clamping plate 253 is fixedly connected to the output end of the second electric telescopic rod 252. The clamping plate 253 is slidably installed on one side of the connecting plate 251.

[0028] When the present invention is in use, after the metal part is placed on the top of the base plate 1, the metal part needs to be fixed, and the output shaft of the first motor 223 drives the pulley 224 to rotate. After the belt 225 is driven, the bidirectional threaded rod 222 starts to rotate. Under the limit of the limit rod 24, the two slides 23 approach each other. The slide 23 drives the connecting plate 251 to approach the metal part through the second motor 25. At this time, the second electric telescopic rod 252 extends to make the splint 253 close to the bottom of the connecting plate 251. Then the two connecting plates 251 and the splint 253 are pressed against the metal part and clamped. At this time, the metal part can be welded. After the welding of one side of the component is completed, the clamping plate 253 is raised so that the metal component is between the connecting plate 251 and the clamping plate 253, and then the output end of the second electric telescopic rod 252 is extended to clamp the metal component. At this time, the output end of the first electric telescopic rod 22 is contracted, and the connecting block 221 and the two-way threaded rod 222 are moved upward. The limiting rod 24 slides on the inner surface of the third groove 231, and at the same time, the metal component is also lifted. Then, the two connecting plates 251 are rotated synchronously through the output shafts of the two second motors 25, and the metal component can be turned over. After the turning is completed, the metal component is placed on the top of the base plate 1 and clamped, and the metal component is welded again.

[0029] Further, such as Figure 4 As shown, a fourth groove 3 is provided at the bottom of the top plate 2, a threaded rod 31 is rotatably installed in the inner cavity of the fourth groove 3, one end of the threaded rod 31 is fixedly connected to a third motor 311, and the third motor 311 is fixedly installed on one side of the top plate 2, a slider 32 is slidably installed on the inner surface of the fourth groove 3, a fifth groove 321 is provided on one side of the slider 32, the connecting post 33 is slidably installed on the inner surface of the fifth groove 321, a limiting post 34 is fixedly installed on the inner surface of the fifth groove 321, and the limiting post 34 is slidably connected to the connecting post 33; A fourth motor 35 is fixedly mounted on one side of the connecting column 33 , and a gear 36 is fixedly connected to the output shaft of the fourth motor 35 . A rack 37 is fixedly mounted on one side of the slider 32 , and the rack 37 and the gear 36 are meshed with each other.

[0030] When the present invention is in use, the laser welder 42 can be changed in position through the connecting column 33. When in use, the threaded rod 31 is rotated by the output shaft of the third motor 311, so that the threaded rod 31 can drive the slider 32 to slide along the inner cavity of the fourth groove 3. The gear 36 is rotated by the output shaft of the fourth motor 35. When the gear 36 rotates, the fourth motor 35 and the connecting column 33 can slide along the inner cavity of the fifth groove 321.

[0031] Further, such as Figure 5As shown, the bottom of the connecting column 33 is fixedly connected to the fifth motor 4, the output shaft of the fifth motor 4 is fixedly connected to the horizontal plate 41, the top of the horizontal plate 41 is fixedly mounted with a second cylinder 412 and a first cylinder 411, the output end of the first cylinder 411 is fixedly connected to a first mounting plate 4111, the laser welder 42 is fixedly mounted on the bottom of the first mounting plate 4111, and one of the suction pipes 461 passes through the first mounting plate 4111; Valves are fixedly installed on the outer surfaces of the two suction pipes 461, the output end of the second cylinder 412 is fixedly connected to the second mounting plate 4121, two buffer plates 43 are fixedly installed on the bottom of the second mounting plate 4121, the bottoms of the two buffer plates 43 are respectively fixedly connected to the sixth motor 44 and the collecting box 442, the output shaft of the sixth motor 44 is fixedly connected to the friction roller 441, and one end of the suction pipe 461 passes through the inner cavity of the collecting box 442.

[0032] When the present invention is in use, after welding is completed, it is necessary to clean the welding slag on the metal parts. The output shaft of the fifth motor 4 drives the horizontal plate 41 to rotate, so that the friction roller 441 is at the top of the welding part of the metal parts. The output end of the second cylinder 412 is extended to make the friction roller 441 close to the welding part. The output shaft of the sixth motor 44 drives the friction roller 441 to rotate so as to clean the welding slag. When cleaning the welding slag, the valve on the suction pipe 461 near the laser welder 42 is closed. At this time, the fan 45 sucks air through the suction pipe 461 near the collection box 442. The welding slag cleaned by the friction roller 441 will be sucked into the inner cavity of the collection box 442 through the suction. Tube 461 enters into the suction pipe 461 to inoculate the welding slag, which is convenient for the staff to clean the welding slag later. The presence of welding slag will cause the surface of the metal parts to be uneven. In order to prevent the friction roller 441 from being lifted up by the welding slag and unable to return to its initial state to continue the slag removal work, the two buffer plates 43 can increase the range of movement of the friction roller 441 and the collection box 442. Similarly, during welding, the valve of the suction pipe 461 close to the side of the friction roller 441 is also closed, and the outlet pipe 451 is on the side of the collection box 442. When cleaning the welding slag, the air discharge of the outlet pipe 451 will not affect the welding slag entering the inner cavity of the collection box 442.

[0033] Further, such as Figure 7As shown, a support plate 5 is slidably installed in the inner cavity of the second groove 12, and several vertical plates 51 are fixedly installed on the top of the support plate 5. Four vertical rods 52 are fixedly installed on the bottom of the base plate 1. The four vertical rods 52 are divided into two groups of two. One side of the two vertical rods 52 in the same group is respectively rotatably connected to the second rotating plate 54 and the first rotating plate 53. The first rotating plate 53 and the second rotating plate 54 are rotatably connected to the Y-shaped plate 55 together. The length of the first rotating plate 53 is greater than that of the second rotating plate 54. A seventh motor 56 is fixedly installed on one side of the vertical rod 52, and the output shaft of the seventh motor 56 is fixedly connected to the second rotating plate 54.

[0034] When the present invention is in use, since the surface temperature of the metal parts that have just been welded is too high, the metal parts cannot be moved manually. Therefore, after welding is completed, the output shaft of the seventh motor 56 drives the second rotating plate 54 to rotate. Under the pull of the first rotating plate 53, the Y-shaped plate 55 will drive the support plate 5 and the vertical plate 51 to make intermittent movements upward and to one side. When the vertical plate 51 moves upward, the metal parts can be lifted up, and when the vertical plate 51 moves to one side, the metal parts can be moved to one side with it, thereby completing the movement of the metal parts.

[0035] Working principle: When the present invention is in use, the metal parts to be welded are first placed on the top of the base plate 1, and then the pulley 224 is rotated by the output shaft of the first motor 223 through the belt 225 to transmit the two-way threaded rod 222. When the two-way threaded rod 222 rotates, it can drive the two slides 23 to approach each other. The two slides 23 further drive the two connecting plates 251 to approach each other and clamp the metal parts. After welding one side of the metal parts, the metal parts need to be flipped over. At this time, the bottom of the connecting plate 251 is in the inner cavity of the first groove 11, and the output end of the second electric telescopic rod 252 drives the clamping plate 253 to move downward to cooperate with the connecting plate 251 to clamp the metal parts. Then, the output end of the first electric telescopic rod 22 is contracted and the two-way threaded rod 222 drives the slide 23 upward. At the same time, the slide 23 drives the second motor 25 and the clamped metal parts upward. Then, the output shaft of the second motor 25 drives 215 to rotate to realize the flipping of the metal parts, and then the clamping plate 253 is placed in the inner cavity of the first groove 11. After the metal parts are clamped, the metal parts can be welded again.

[0036] During welding, the fan 45 can absorb the fume generated by welding through the purification box 46 and the suction pipe 461, and purify the fume through the filter plate 462 and the activated carbon 463 in the inner cavity of the purification box 46. After welding is completed, the fifth motor 4 output shaft drives the horizontal plate 41 to rotate so that the friction roller 441 is at the top of the welding part, and the sixth motor 44 output shaft drives the friction roller 441 to rotate so as to clean the welding slag on the metal parts. The welding slag can be sucked into the inner cavity of the purification box 46 through the collection box 442 through the suction pipe 461 to clean the welding slag. The concentration of rows makes it easier for the staff to clean the welding slag later. The second rotating plate 54 is driven to rotate by the seventh motor 56. The first rotating plate 53 is pulled to make the Y-shaped plate 55 slide upward and to one side with the support plate 5 and the vertical plate 51. When in use, several vertical plates 51 first lift the metal parts, and then push the metal parts to one side to complete the movement of the metal parts. After moving the metal parts to the other side, the top of the bottom plate 1 can continue to weld other metal parts, and at the same time, the heat dissipation of the metal parts can be accelerated through the air outlet pipe 451.
