[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a laser marking machine, including a workbench 1, the upper surface of the workbench 1 is fixedly connected to a support frame 2, the upper surface of the support frame 2 is fixedly connected to a hydraulic cylinder 3, the output end of the hydraulic cylinder 3 is fixedly connected to a sliding plate 4, the upper surface of the sliding plate 4 is fixedly connected to a limit rod, the limit rod is slidably connected to the inside of the support frame 2, the lower surface of the sliding plate 4 is fixedly connected to a marking mechanism 5, one side of the outer wall of the sliding plate 4 is rotatably connected to a connecting rod 6, the outer wall of the connecting rod 6 is provided with a cleaning component 7, the inner wall of the workbench 1 is fixedly connected to a collecting box 8, the inside of the collecting box 8 is slidably connected to a collecting box 9, the bottom of the inner wall of the workbench 1 is fixedly connected to an air pump 10, the input end of the air pump 10 is arranged through the inside of the collecting box 8, and the output end of the air pump 10 is arranged through the working Inside the workbench 1, a collecting bucket 11 is fixedly connected to the upper surface of the collecting box 8, and a plurality of transmission tubes 12 are fixedly connected to one side of the outer wall of the collecting bucket 11, one end of the transmission tube 12 is arranged to penetrate inside the workbench 1, and one end of the transmission tube 12 is fixedly connected to a dust collecting box 13, a motor 22 is fixedly connected to the top of the inner wall of the workbench 1, and a gear 23 is fixedly connected to the output end of the motor 22, and a left-right symmetrical clamping plate 24 is slidably connected inside the workbench 1, and a rack plate 25 is fixedly connected to the lower surface of the clamping plate 24, and the rack plate 25 is meshed with the gear 23; the cleaning assembly 7 includes an articulated seat 701, which is rotatably connected to the outer wall of the connecting rod 6, and the articulated seat 701 is slidably connected to the inside of the workbench 1, and a cleaning roller 702 is rotatably connected inside the articulated seat 701;

[0025] Specifically, the workpiece is first placed on the workbench 1, and then, when the motor 22 is started, the rotation of the motor 22 is transmitted to the rack plate 25 through the gear 23, so that the rack plate 25 is meshed and rotated. This rotation relationship can drive the clamping plate 24 on the rack plate 25, thereby clamping the workpiece. In this process, the workpiece is stably fixed on one side of the clamping plate 24, avoiding the reduction of processing accuracy and safety hazards caused by the shaking of the workpiece. Then the hydraulic cylinder 3 is started to drive the sliding plate 4 to move. The movement of the sliding plate 4 drives the articulated seat 701 on the outer wall of the connecting rod 6 to slide within the workbench 1. This design ensures the stability and accuracy of the cleaning process. Next, the articulated seat 701 drives the cleaning roller 702 to roll on the surface of the workpiece. In this process, the cleaning roller 702 can effectively remove dust on the surface of the workpiece, thereby achieving the effect of facilitating the cleaning of dust on the surface of the workpiece. This design improves cleaning efficiency and reduces the labor intensity of workers. In order to ensure the cleanliness of the working environment, the air pump 10 is started to collect the remaining dust through the dust box 13 and enter the multiple transmission pipes 12. In this way, the dust is effectively collected and will not affect the marking work. When the transmission pipe 12 is full of dust, the dust is transferred to the collection bucket 11 through the transmission pipe 12 for unified collection. The collection bucket 11 transfers the dust to the collection box 9 for filtering and collection. This design ensures the effective collection of dust and avoids the waste of resources.

[0026] Reference Figure 2 , Figure 4 and Figure 5 The upper surface of the workbench 1 is fixedly connected with an anti-skid pad 14, and a left-right symmetrical hinge block 15 is arranged just above the anti-skid pad 14, and the two hinge blocks 15 are fixedly connected to the lower surface of the sliding plate 4; the outer walls of the two hinge blocks 15 are fixedly connected with left-right symmetrical fixed plates 16, and the outer wall of the fixed plate 16 is rotatably connected with a rotating plate 17; the rotating plate 17 is rotatably connected with a rotating roller 18 inside, and the rotating roller 18 is arranged just above the anti-skid pad 14; a hook 19 is fixedly connected to one side of the outer wall of the fixed plate 16, and a hook 20 is fixedly connected to one side of the outer wall of the rotating plate 17; a reset spring 21 is arranged between the hook 19 and the hook 20; a plurality of transmission pipes 12 are respectively arranged on both sides of the inside of the collecting bucket 11 and the rear side of the inside;

[0027] Specifically, the hydraulic cylinder 3 is started to drive the sliding plate 4 to move. In this process, the rotating roller 18 will be pressed down with the movement of the sliding plate 4. Then, the rotating force of the rotating roller 18 is used to drive the rotating plate 17 to stretch the reset spring 21. At this time, the reset spring 21 is subjected to pressure and will store energy. The stored pressure is then transmitted to the rotating roller 18 through the reaction force of the reset spring 21. The rotating roller 18 applies pressure on both sides of the workpiece, thereby stabilizing the workpiece and preventing it from deflecting. In addition, the anti-skid pad 14 works in conjunction with the rotating roller 18 to further reduce the possibility of workpiece deflection. Finally, the marking work is performed by starting the marking mechanism 5.

[0028] Working principle: When it is necessary to mark a workpiece, the workpiece is placed on the workbench 1 and the motor (22) is started. The motor (22) drives the gear (23) to mesh and rotate with the rack plate (25), thereby facilitating the clamping plate (24) to clamp the workpiece. The clamping plate (24) clamps the workpiece, thereby achieving the effect of initially stabilizing the workpiece. The hydraulic cylinder 3 is started to drive the sliding plate 4 to move. The sliding plate 4 drives the hinge seat 701 on the outer wall of the connecting rod 6 to slide within the workbench 1. The hinge seat 701 drives the cleaning roller 702 to roll on the surface of the workpiece, thereby achieving the effect of facilitating cleaning of dust on the surface of the workpiece. At the same time, the air pump 10 is started. The air pump 10 collects the remaining dust in an enclosed manner through the dust collecting box 13 and enters the interior of multiple transmission pipes 12. At this time, the dust is transmitted through the transmission pipe 12 to the interior of the collecting bucket 11 for unified collection. At this time, the collecting bucket 11 transmits the dust to the interior of the collecting box 9 for filtering and collection, and the excess gas is discharged from the interior of the workbench 1.

[0029] Secondly, when the cleaning work is completed, the rotating roller 18 will be driven to press down through the sliding plate 4. At this time, the rotating roller 18 will drive the rotating plate 17 to stretch the reset spring 21, so that the reset spring 21 is subjected to pressure. At this time, the pressure is transmitted to the rotating roller 18 through the reaction force of the reset spring 21. The pressure is applied to both sides of the workpiece through the rotating roller 18, so as to achieve the effect of stabilizing the workpiece and preventing it from shifting. Through the cooperation of the anti-slip pad 14, the effect of further preventing the workpiece from shifting is achieved. At this time, the marking work can be achieved by starting the marking mechanism 5.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
