[0014] Preferably, the side of the rotating sleeve away from the annular bearing A is fixedly connected to the annular bearing B, one side of the annular bearing B is rotatably connected to one side of the air deflector B, and the outer wall of the air deflector B is fixedly connected to a connecting rod.

[0015] Preferably, one end of the connecting rod away from the deflector B is fixedly connected to the outer wall of the deflector A, and the connecting rod is a U-shaped rod structure, and the connecting rod is used to keep the deflector A and the deflector B stationary.

[0016] Preferably, the stop block is used to prevent the air deflector A from being excessively lifted and rotated, and the counterweight block is used to counterweight the air deflector A.

[0017] The present invention provides a laser processing device having the following beneficial effects:

[0018] 1. The present invention sets a mobile jet mechanism so that the blown wind can clean the metal slag locally and in real time at the marking position, avoiding the debris becoming an obstacle in the laser path, hindering the propagation of the laser beam and affecting the marking efficiency. The adaptive local blowing effect can reduce the overall interference with the surface of the metal plate and reduce the risk of surface damage caused by excessive cleaning.

[0019] 2. The present invention sets a mobile jet mechanism to achieve that the farther the laser marking machine moves longitudinally, the greater the angle at which the air deflector B is lifted. Then, the wind blown out through the air deflector B will reach farther and blow specifically to the position where the laser marking machine marks on the metal plate. The closer the distance the laser marking machine moves longitudinally, the smaller the angle at which the air deflector B is lifted. Similarly, the air deflector B maintains a targeted orientation toward the laser marking machine to mark the metal plate. When marking of various orientations of the metal plate is completed, the air deflector B can automatically align with its marking orientation for local blowing to blow away the metal slag blocking the laser, thereby ensuring the stability and efficiency of laser marking.

[0020] 3. The present invention sets a mobile jet mechanism, and each time the metal plate is marked, the air guide cover B is lifted and lowered when it moves quickly, so as to realize an overall shaking of the air guide cover B, the rotating sleeve and the air guide cover A. The shaking can be used to stably blow and clean the laser marking area locally, and at the same time, the upper and lower ranges are moved at intervals, so that the metal slag blown away to the vicinity of the marking is also sufficiently away from the area, and the shaking can effectively prevent the blockage problem caused by long-term ventilation of the inner wall of the ventilation slot.

[0021] 4. The present invention sets a mobile jet mechanism. When the air is discharged through the air deflector B, a small amount of air will also be discharged from the air deflector A, the rotating sleeve and the ventilation grooves on the outer wall of the air deflector B, thereby realizing a slight flow of air to the entire metal plate area. The slight flow can avoid interference with the metal plate during laser marking, and at the same time, it can clean up the remaining residues blown away by the wind from the air deflector B at the marked position, thereby avoiding the problem of remaining waste residues when the subsequent positions of the metal plate are marked.

[0022] 5. The present invention sets a rotating mechanism, and the rotating sleeve performs relative rotational movement with the air deflector A and the air deflector B through the annular bearing A and the annular bearing B. The air deflector A and the air deflector B are fixed by the connecting rod and cannot rotate. Therefore, the continuous rotation of the rotating sleeve can disperse the air discharged through the ventilation slots in the rotating sleeve through its rotation, further improving the uniform spraying effect of the air dispersed outward through the ventilation slots, fully driving the air around the metal plate to flow to a certain extent, maintaining the overall heat dissipation and cooling effect, and reducing the sputtered metal slag on the metal plate.

DETAILED DESCRIPTION

[0038] Example 1: Please refer to Figure 1-5The present invention provides a technical solution: a laser processing device, comprising a laser processing table 2, a processing plate 1 is fixedly connected to the top of the laser processing table 2, a mobile telescopic machine 5 is fixedly connected to the top of the laser processing table 2, a fixed block 6 is arranged on one side of the mobile telescopic machine 5, a laser marking machine 7 is fixedly connected to the bottom of the fixed block 6, and a mobile jet mechanism 3 is arranged on the top of the processing plate 1;

[0039] The mobile jet mechanism 3 comprises:

[0040] The fixing bar 301 is a long strip-shaped plate-like structure. The bottom of the fixing bar 301 is fixedly connected to the top of the processing plate 1. The outer wall of the fixing bar 301 is fixedly connected with a sliding block 302. The sliding block 302 is a square block-shaped structure. The fixing bar 301 is used to allow the sliding block 302 to slide thereon;

[0041] The tuyere pipe 306 is a circular annular hollow structure. One side of the tuyere pipe 306 is fixedly connected to one side of the sliding block 302. The inner wall of the sliding block 302 is rotatably connected to a bearing ring. The inner wall of the bearing ring is fixedly connected to a blade 305. One side of the blade 305 is fixedly connected to a rotating shaft 304. One side of the sliding block 302 is fixedly connected to a motor 303. The output end of the motor 303 is fixedly connected to one end of the rotating shaft 304. The tuyere pipe 306 is used to guide air.

[0042] When in use, the object to be laser marked is placed on the processing plate 1, and then the mobile telescopic machine 5 is started to control the fixed block 6 and the laser marking machine 7 to move forward, backward, left and right, so that the laser marking machine 7 can freely laser mark the metal plate below;

[0043] Example 2: Please refer to Figure 1-11 On the basis of the first embodiment, the present invention provides a technical solution: the inner walls of the air outlet pipe 306 are rotatably connected with hinge shafts 307 on both sides, and the outer wall of the hinge shaft 307 is rotatably connected with a guide cover A308, and the guide cover A308 is a circular ring structure.

[0044] A stopper 310 is fixedly connected to the top of the air outlet pipe 306 , a rotating sleeve 312 is provided on one side of the air guide cover A308 , and an air guide cover B313 is provided on one side of the rotating sleeve 312 .

[0045] A counterweight block 311 is fixedly connected to the bottom of the deflector A308, an elastic rope 314 is fixedly connected to the top of the deflector B313, one end of the elastic rope 314 is fixedly connected to a telescopic rod 315, and the top of the telescopic rod 315 is fixedly connected to the bottom of the fixed block 6;

[0046] While the object is moving and marking the surface of the metal plate, the motor 303 is started, the motor 303 controls the rotation of the shaft 304 and the blade 305, and the blade 305 is used to blow air into the air outlet pipe 306, and the air outlet pipe 306 blows the flowing air outward to complete the blowing of the processing plate 1, so that the laser marking position is reduced by air flow and the metal debris splashed on the metal plate during marking;

[0047] When the fixed block 6 and the laser marking machine 7 move, the fixed block 6 will drive the telescopic rod 315 at the bottom to move synchronously, and when the laser marking machine 7 and the fixed block 6 move laterally along the path of the fixed bar 301, the elastic rope 314 will be pulled by the telescopic rod 315, and the elastic rope 314 will be used to pull the air deflector B313 to move synchronously, and the air deflector B313, the rotating sleeve 312, and the air deflector A308 are hinged to the air outlet pipe 306 through the hinge shaft 307, so that the air deflector B313, the rotating sleeve 312, and the air deflector A308 can be hinged and rotated up and down on the air outlet pipe 306 but cannot rotate laterally, so that when the air deflector B313 is pulled and moved laterally by the elastic rope 314, the air deflector B313 will rotate The sleeve 312 and the air guide cover A308 drive the tuyere tube 306 and the sliding block 302 to move horizontally on the fixed bar 301, so that when the laser marking machine 7 moves horizontally during marking, the sliding block 302 will also move horizontally synchronously therewith, so that the wind blown out by the blade 305 will enter the air guide cover A308 through the tuyere tube 306 and finally blow out through the air guide cover B313, so that the blown wind can clean the metal slag locally at the marking position in real time, avoiding the debris from becoming an obstacle in the laser path, hindering the propagation of the laser beam, and affecting the marking efficiency. In addition, the adaptive local blowing effect can reduce the overall interference with the surface of the metal plate and reduce the risk of surface damage caused by excessive cleaning.

[0048] In addition, the fixed block 6 and the laser marking machine 7 do not move laterally along the path of the fixed bar 301, but move longitudinally. When the laser marking machine 7 is used to mark the surface of the metal plate, when moving longitudinally, the telescopic rod 315 will pull the air deflector B313 through the elastic rope 314, and the elastic rope 314 is elastic. When the air deflector B313 is pulled, since the sliding block 302 cannot move longitudinally, the air deflector B313 will be lifted when it is pulled longitudinally by the elastic rope 314. The air deflector A308 is hinged and rotated on the hinge shaft 307 to lift it, so that the air deflector A308, the rotating sleeve 312, and the air deflector B313 are lifted as a whole. Since a counterweight block 311 for counterweight is arranged at the bottom of the air deflector A308, the longer the distance the laser marking machine 7 moves longitudinally, the longer the elastic rope 314 is stretched, and the elastic rope 314 overcomes the gravity of the counterweight block 311. The larger the angle, the higher the angle at which the air deflector A308 is rotated and lifted on the outer wall of the hinge shaft 307. Therefore, when the laser marking machine 7 is at different distances from the air deflector B313 in real time, the air deflector B313, the rotating sleeve 312 and the air deflector A308 are lifted to different degrees, so that the farther the laser marking machine 7 moves longitudinally, the greater the angle at which the air deflector B313 is lifted. Then, the wind blown out through the air deflector B313 is blown farther, and blows to the position where the laser marking machine 7 marks the metal plate. The closer the distance of the longitudinal movement of the laser marking machine 7 is, the smaller the angle at which the air deflector B313 is lifted. Similarly, the air deflector B313 is lifted in a targeted manner toward the position where the laser marking machine 7 marks the metal plate. When marking of each position of the metal plate is completed, the air deflector B313 can automatically align with its marking position for local blowing to blow away the metal slag blocking the laser, thereby ensuring the stability and efficiency of laser marking.

[0049] When the air guide cover B313 is lifted to be parallel to the air outlet pipe 306, it cannot be lifted further, and the upper part of the inner wall of the air guide cover A308 will abut against the top of the stopper 310, thereby preventing the air guide cover A308 from excessively rotating and lifting, so that the air guide cover B313 remains parallel and performs the farthest blowing;

[0050] When the elastic rope 314 pulls the air deflector B313 laterally, when it is pulled quickly, the elastic rope 314 will be deformed and overcome a certain gravity of the counterweight block 311, so that the air deflector A308 and the air deflector B313 are hinged, rotated and lifted. Then, when the laser marking machine 7 slows down and performs slow laser marking, the elastic rope 314 slowly moves the air deflector B313, and it cannot overcome the gravity of the counterweight block 311, so that the air deflector A308, the rotating sleeve 312, and the air deflector B313 also fall down with gravity. Each time the metal plate is marked, the guide cover B313 is lifted and dropped when it is moved quickly, so that the guide cover B313, the rotating sleeve 312 and the guide cover A308 are shaken as a whole. The shaking can be used to stably blow and clean the laser marking part locally, and the upper and lower ranges are moved at intervals to sufficiently keep the metal slag blown away near the marking part. The shaking can also effectively prevent the blockage problem caused by long-term ventilation of the inner wall of the ventilation slot 309.

[0051] When the air is discharged through the air guide cover B313, a small amount of air will also be discharged from the air guide cover A308, the rotating sleeve 312 and the ventilation slots 309 on the outer wall of the air guide cover B313, so as to achieve a slight flow of air in the metal plate area. This slight flow can avoid interference with the metal plate during laser marking, and at the same time, it can remove the remaining residues blown away by the wind from the air guide cover B313 at the marked position, so as to avoid the problem of the presence of remaining waste residues at the subsequent positions of the metal plate being marked.

[0052] Example 3: Please refer to Figure 1-14 On the basis of the first and second embodiments, the present invention provides a technical solution: a rotating mechanism 4 is arranged on the outer wall of the rotating sleeve 312, and the rotating mechanism 4 includes an annular bearing A401, one side of the annular bearing A401 is fixedly connected to one side of the rotating sleeve 312, and the other side of the annular bearing A401 is rotatably connected to one side of the air guide cover A308.

[0053] The side of the rotating sleeve 312 away from the annular bearing A401 is fixedly connected to the annular bearing B402, one side of the annular bearing B402 is rotatably connected to one side of the air deflector B313, and the outer wall of the air deflector B313 is fixedly connected to a connecting rod 404.

[0054] One end of the connecting rod 404 away from the air deflector B313 is fixedly connected to the outer wall of the air deflector A308. The connecting rod 404 is a U-shaped rod structure. The connecting rod 404 is used to keep the air deflector A308 and the air deflector B313 stationary.

[0055] The stopper 310 is used to prevent the air deflector A308 from being excessively lifted and rotated, and the counterweight 311 is used to counterweight the air deflector A308;

[0056] When the air quickly passes through the air guide cover A308 and the rotating sleeve 312 and is ejected from the air guide cover B313, the inclined plate 403 on the inner wall of the rotating sleeve 312 will be moved. The inclined plate 403 will be moved by the air and will use its inclined surface to drive the rotating sleeve 312 to rotate. The rotating sleeve 312 performs relative rotational motion with the air guide cover A308 and the air guide cover B313 through the annular bearing A401 and the annular bearing B402. The air guide cover A308 and the air guide cover B313 are fixed by the connecting rod 404 and cannot rotate. Therefore, the continuous rotation of the rotating sleeve 312 can disperse the air discharged through the ventilation slots 309 in the rotating sleeve 312 through its rotation, further enhancing the uniform spraying effect of the air dispersed outward through the ventilation slots 309, fully driving the air around the metal plate to flow to a certain extent, while maintaining the overall heat dissipation and cooling effect, it also reduces the sputtered metal slag on the metal plate.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
