DETAILED DESCRIPTION

[0038] Example One: Please refer to Figures 1-5The application provides a technical scheme: a laser processing device, comprising a laser processing table 2, a processing plate 1 fixedly connected to the top of the laser processing table 2, a movable telescopic machine 5 fixedly connected to the top of the laser processing table 2, a fixed block 6 arranged on one side of the movable telescopic machine 5, a laser marking machine 7 fixedly connected to the bottom of the fixed block 6, and a movable air jet mechanism 3 arranged on the top of the processing plate 1.

[0039] The movable air jet mechanism 3 comprises:

[0040] A fixed strip 301 in a long strip-shaped plate structure, the bottom of the fixed strip 301 being fixedly connected to the top of the processing plate 1, and a sliding block 302 fixedly connected to the outer wall of the fixed strip 301, the sliding block 302 being in a square block structure, the fixed strip 301 being used for allowing the sliding block 302 to slide thereon;

[0041] A tuyere pipe 306 in a circular ring-shaped hollow structure, one side of the tuyere pipe 306 being fixedly connected to one side of the sliding block 302, a bearing ring being rotatably connected to the inner wall of the sliding block 302, a blade 305 being fixedly connected to the inner wall of the bearing ring, one side of the blade 305 being fixedly connected to a rotating shaft 304, one side of the sliding block 302 being fixedly connected to a motor 303, the output end of the motor 303 being fixedly connected to one end of the rotating shaft 304, and the tuyere pipe 306 being used for guiding air flow;

[0042] In use, an article needing laser marking is placed on the processing plate 1, then the movable telescopic machine 5 is started to control the fixed block 6 and the laser marking machine 7 to move forward and backward and left and right, so that the laser marking machine 7 can freely mark the metal plate below;

[0043] Embodiment two: please refer to Figures 1-11 On the basis of embodiment one, the application provides a technical scheme: the inner wall of the tuyere pipe 306 is rotatably connected with a hinge shaft 307 on both sides, the hinge shaft 307 is rotatably connected with a flow guide cover A 308 on the outer wall, and the flow guide cover A 308 is in a circular ring structure.

[0044] The top of the tuyere pipe 306 is fixedly connected with a stop block 310, one side of the flow guide cover A 308 is provided with a rotating sleeve 312, and one side of the rotating sleeve 312 is provided with a flow guide cover B 313.

[0045] The bottom of the flow guide cover A 308 is fixedly connected with a counterweight 311, the top of the flow guide cover B 313 is fixedly connected with an elastic rope 314, one end of the elastic rope 314 is fixedly connected with a telescopic rod 315, and the top end of the telescopic rod 315 is fixedly connected with the bottom of the fixed block 6.

[0046] When the object moves on the surface of the metal plate for marking, the motor 303 is started, the motor 303 controls the rotation of the shaft 304 and the blade 305, the blade 305 blows air into the air outlet pipe 306, the air outlet pipe 306 blows the flowing air outward, completes the blowing on the processing plate 1, and reduces the metal debris splashed on the metal plate during marking through air flow;

[0047] When the fixed block 6 and the laser marking machine 7 move, the fixed block 6 will drive the bottom telescopic rod 315 to move synchronously, and when the laser marking machine 7 and the fixed block 6 move transversely along the path of the fixed strip 301, the telescopic rod 315 will pull the elastic rope 314, the elastic rope 314 will pull the fairing B 313 to move synchronously, and the fairing B 313, the rotating sleeve 312 and the fairing A 308 are hinged with the air outlet pipe 306 through the hinge shaft 307, so that the fairing B 313, the rotating sleeve 312 and the fairing A 308 can rotate up and down on the air outlet pipe 306 but cannot rotate horizontally, so that when the fairing B 313 is pulled and moved horizontally by the elastic rope 314, the fairing B 313 will drive the air outlet pipe 306 and the sliding block 302 to move horizontally on the fixed strip 301 through the rotating sleeve 312 and the fairing A 308, so that when the laser marking machine 7 moves horizontally during marking, the sliding block 302 will also move horizontally synchronously, so that the wind blown by the blade 305 will enter the fairing A 308 through the air outlet pipe 306 and finally blow out through the fairing B 313, so that the blown wind can clean the metal slag of the marking position in real time, avoid the problem that the debris becomes an obstacle in the laser path and blocks the propagation of the laser beam, and affect the marking efficiency, and the self-adaptive local blowing function can reduce the overall interference on the surface of the metal plate and reduce the risk of surface damage caused by excessive cleaning;

[0048] Furthermore, the fixed block 6 and the laser marking machine 7 do not move laterally along the path of the fixed strip 301, but rather longitudinally. When the laser marking machine 7 marks the surface of the metal plate, during longitudinal movement, the telescopic rod 315 pulls the guide shield B313 via the elastic rope 314. Since the elastic rope 314 is elastic, when the guide shield B313 is pulled, because the sliding block 302 cannot move longitudinally, the guide shield B313 is lifted by the longitudinal pull of the elastic rope 314. This is achieved by the guide shield A308 being hinged and rotated on the hinge shaft 307, thus lifting the guide shield A308, the rotating sleeve 312, and the guide shield B313 as a whole. Because the bottom of the guide shield A308 is equipped with a counterweight block 311, the further the laser marking machine 7 moves longitudinally, the longer the elastic rope 314 is stretched, and the greater the weight of the counterweight block 311 becomes. The larger the diameter, the higher the angle at which the guide shroud A308 rotates and rises on the outer wall of the hinge shaft 307. This allows the guide shroud B313, rotating sleeve 312, and guide shroud A308 to rise to different degrees depending on the distance between the laser marking machine 7 and the guide shroud B313. The further the laser marking machine 7 moves longitudinally, the greater the angle at which the guide shroud B313 rises, and the farther the air blown out through the guide shroud B313 travels, directly targeting the position where the laser marking machine 7 marks the metal plate. Conversely, the closer the laser marking machine 7 moves longitudinally, the smaller the angle at which the guide shroud B313 rises, maintaining a targeted orientation towards the direction the laser marking machine 7 marks the metal plate. When marking various positions on the metal plate, the guide shroud B313 can automatically aim at the marking position and blow away any metal debris blocking the laser, ensuring the stability and efficiency of laser marking.

[0049] When the air guide shroud B313 is raised to be parallel with the air outlet pipe 306, it cannot be raised further. The upper part of the inner wall of the air guide shroud A308 will abut against the top of the baffle 310, thereby preventing the air guide shroud A308 from being excessively rotated and raised, so that the air guide shroud B313 remains in a parallel state and blows air to the farthest distance.

[0050] When the elastic rope 314 pulls the fairing B 313 laterally, the elastic rope 314 is deformed and lifts the fairing A 308 and the fairing B 313 when the elastic rope 314 is pulled quickly, and the elastic rope 314 cannot overcome the gravity of the counterweight 311 when the elastic rope 314 moves the fairing B 313 slowly when the laser marking machine 7 moves slowly, so that the fairing A 308, the rotating sleeve 312, and the fairing B 313 fall under the gravity, but the fairing B 313 is lifted and falls once every time the metal plate is marked quickly, so that the fairing B 313, the rotating sleeve 312, and the fairing A 308 are shaken once, and the metal slag blown to the marking position is removed, and the clogging problem caused by the long-time ventilation of the inner wall of the ventilation groove 309 is effectively prevented.

[0051] When the air is discharged through the fairing B 313, a small amount of air is also discharged from the ventilation grooves 309 formed in the outer walls of the fairing A 308, the rotating sleeve 312, and the fairing B 313, so that the air in the metal plate region is slightly flowed, which can avoid the interference of the laser marking on the metal plate and remove the remaining slag blown by the air in the fairing B 313, so that the subsequent position of the metal plate is not marked by the remaining slag.

[0052] Embodiment three: please refer to Figures 1-14 On the basis of the embodiments one and two, the application provides a technical solution: the rotating sleeve 312 is provided with a rotating mechanism 4, the rotating mechanism 4 comprises an annular bearing A 401, one side of the annular bearing A 401 is fixedly connected with one side of the rotating sleeve 312, and the other side of the annular bearing A 401 is rotatably connected with one side of the fairing A 308.

[0053] The rotating sleeve 312 is fixedly connected with an annular bearing B 402 away from the annular bearing A 401, one side of the annular bearing B 402 is rotatably connected with one side of the fairing B 313, and the outer wall of the fairing B 313 is fixedly connected with a connecting rod 404.

[0054] One end of the connecting rod 404 away from the fairing B 313 is fixedly connected with the outer wall of the fairing A 308, the connecting rod 404 is a U-shaped rod structure, and the connecting rod 404 is used to keep the fairing A 308 and the fairing B 313 stationary.

[0055] The stopper 310 is used to prevent the fairing A 308 from being lifted too much, and the counterweight 311 is used to counterweight the fairing A 308.

[0056] When the air is rapidly ejected from the inside of the fairing B 313 through the fairing A 308, the rotating sleeve 312, the inclined plate 403 in the inner wall of the rotating sleeve 312 is pushed, and the inclined plate 403 is pushed by the air to rotate the rotating sleeve 312 by using the inclined surface, and the rotating sleeve 312 rotates relative to the fairing A 308 and the fairing B 313 through the relative rotation of the annular bearing A 401 and the annular bearing B 402, and the fairing A 308 and the fairing B 313 are fixed by the connecting rod 404 and cannot rotate, so that the continuous rotation of the rotating sleeve 312 can disperse the air discharged through the ventilation slot 309 in the rotating sleeve 312 by rotating, further improving the uniform spraying effect of the air dispersed outward through the ventilation slot 309, fully driving the air around the metal plate to flow, maintaining the overall heat dissipation and cooling effect, and reducing the sputtering metal slag on the metal plate.

[0057] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
