Description

Technical Field

[0001] The utility model belongs to the technical field of laser equipment, and in particular relates to a cleaning device for a laser marking machine. Background Art

[0002] The cleaning device for laser marking machines plays a vital role in the laser marking process. During the laser marking process, the surface of the material will be ablated by high temperature, generating a large amount of dust and fine particles. If these residues are not removed in time, it will affect the quality and accuracy of the marking. The laser marking process will also produce smoke and harmful gases. These gases need to be discharged in time to keep the working environment clean and safe.

[0003] The patent with publication number CN219900650U in the prior art discloses a cleaning device for a laser marking machine, including a frame, a suction fan and an air duct are provided on the frame, and an absorption component for absorbing particulate matter generated during the laser marking process is provided on the frame. The device absorbs the particulate matter generated during the marking process into the cavity of the mounting plate by installing the suction fan and the air duct on the frame, thereby reducing the possibility of particulate matter being scattered on the equipment and the workpiece. A blocking plate is installed between the air duct and the mounting plate to block the particulate matter from entering the air duct, thereby reducing the impact of the particulate matter entering the air duct on the air duct and the suction fan. The air duct in a fixed position may have the defect of poor adaptability and is not convenient to adjust according to the different shapes and positions of the workpiece. It may not be able to effectively cover all areas that need to be cleaned, resulting in the particulate matter in some areas not being effectively sucked in. As time goes by, a large amount of particulate matter will accumulate on the blocking plate. These particles will gradually block the pores of the blocking plate, reducing the effective ventilation area, causing the wind speed to drop, and affecting the cleaning effect.

[0027] Example

[0028] Reference Figures 1 to 7 , is an embodiment of the present utility model, which provides a cleaning device for a laser marking machine, which can enable the suction head 104 to perform reciprocating motion of a corresponding stroke according to the different shapes and positions of the workpiece, and intermittently clean the particles attached to the surface of the blocking plate 105 during the cleaning process.

[0029] The cleaning mechanism 100 includes a centrifugal fan 101, a flexible hose 102 connected to the suction port of the centrifugal fan 101, a storage box 103 connected to the other end of the flexible hose 102, a suction head 104 fixedly connected to the outside of the storage box 103, and a blocking plate 105 fixedly connected to the inner wall of the storage box 103. The inner cavity of the storage box 103 is connected to the suction head 104.

[0030] It should be noted that through the cooperation of the centrifugal fan 101, the telescopic hose 102, the storage box 103 and the baffle 105, the solid particles generated during the laser marking process can be sucked into the storage box 103 for centralized processing by the staff, and the smoke and harmful gases generated during the laser marking process can be discharged outdoors, thereby keeping the working environment clean and safe.

[0031] The swing mechanism 200 includes a first motor 201 adapted to be installed at the bottom of the workbench T, a turntable 202 fixedly installed at the through end of the first motor 201 through a coupling, a fixed frame 203 fixedly connected to the top of the turntable 202, a threaded rod 204 fixedly installed on the inner wall of the fixed frame 203 through a bearing, an internal thread block 205 threadedly connected to the outer surface of the threaded rod 204, a hinged rod 206 hinged at the top of the internal thread block 205, a support plate 207 hinged at the other end of the hinged rod 206, guide rails 208 fixedly installed on both sides of the top of the workbench T and used in conjunction with the support plate 207, and a cleaning component 209 arranged on the inner surface of the storage box 103 and used in conjunction with the blocking plate 105.

[0032] Specifically, a knob is fixedly connected to the through end of the threaded rod 204 , the outer surface of the internal thread block 205 is in sliding contact with the inner wall of the fixed frame 203 , and the inner surface of the support plate 207 is in sliding contact with the outer surface of the guide rail 208 .

[0033] It should be noted that turning the knob can drive the threaded rod 204 to rotate, and the internal thread block 205 is limited by the fixed frame 203, so that the internal thread block 205 drives the hinged rod 206 and the support plate 207 to move linearly, and then the support plate 207 drives the storage box 103 and the suction head 104 to move synchronously, so that the rotation radius of the hinged rod 206 and the reciprocating motion stroke of the suction head 104 can be flexibly adjusted according to the different shapes and positions of the workpiece.

[0034] Furthermore, the cleaning assembly 209 includes a second motor 209a adapted to be installed on the outer surface of the storage box 103, a driving rod 209b fixedly installed on the output end of the second motor 209a through a coupling, a connecting frame 209c sleeved on the outer surface of the driving rod 209b, a rack 209d fixedly connected to the outside of the connecting frame 209c, and a fixing block 209e respectively fixedly connected to both sides of the outer surface of the storage box 103 and used in conjunction with the rack 209d.

[0035] It should be noted that the rack 209d is limited by the fixing block 209e, so that the rack 209d limits the connecting frame 209c, so that the connecting frame 209c can drive the gear 209f to perform reciprocating linear motion through the rotation of the driving rod 209b.

[0036] Preferably, the outer end surface of the driving rod 209b is in sliding contact with the inner surface of the connecting frame 209c, and the outer surface of the rack 209d is in sliding contact with the inner wall of the fixing block 209e.

[0038] Furthermore, the cleaning assembly 209 also includes a driven shaft 209j rotatably connected to the inner surface of the storage box 103, a groove wheel 209k fixedly mounted on the outer surface of the driven shaft 209j and used in conjunction with the driving wheel 209h, and a scraper 209l fixedly installed on the through end of the driven shaft 209j.

[0039] It should be explained that when the driving wheel 209h rotates into the groove of the groove wheel 209k, it can drive the groove wheel 209k to rotate synchronously. When the driving wheel 209h rotates out of the groove of the groove wheel 209k, the groove wheel 209k is limited by the brake wheel 209i to prevent the groove wheel 209k from continuing to rotate due to inertia.

[0040] Specifically, the outer end surface of the connecting shaft 209 g is fixedly mounted on the outer surface of the storage box 103 via a bearing, and the outer surface of the scraper 209 l is in sliding contact with the outer surface of the blocking plate 105 .

[0041] When in use, turning the knob can drive the threaded rod 204 to rotate, and the internal thread block 205 is limited by the fixed frame 203, so that the internal thread block 205 drives the hinged rod 206 and the support plate 207 to move linearly, and then the support plate 207 drives the storage box 103 and the suction head 104 to move synchronously, so as to adjust the rotation radius of the hinged rod 206 and the reciprocating motion stroke of the suction head 104 to a suitable range according to the different shapes and positions of the workpieces, and at the same time start the centrifugal fan 101, the first motor 201 and the second motor 209a, through the centrifugal fan 101, the telescopic hose 102, the storage box 103 and the blocking plate 10 5, the solid particles generated during the laser marking process are sucked into the storage box 103 for centralized treatment by the staff, and the smoke and harmful gases generated during the laser marking process are discharged outdoors, thereby maintaining a clean and safe working environment. The first motor 201 drives the turntable 202 and the fixed frame 203 to rotate, so that the fixed frame 203 drives the threaded rod 204 and the internal thread block 205 to rotate synchronously, and the internal thread block 205 drives the hinged rod 206 to move, and then the hinged rod 206 drives the support plate 207, the storage box 103 and the suction head 104 to move synchronously, thereby effectively covering the area to be cleaned;

[0042] The second motor 209a drives the driving rod 209b to rotate synchronously, and the fixed block 209e limits the rack 209d, so that the rack 209d limits the connecting frame 209c, so that the connecting frame 209c can drive the gear 209f to perform reciprocating linear motion through the rotation of the driving rod 209b, and then the gear 209f and the connecting shaft 209g cooperate to drive the driving wheel 209h and the brake wheel 209i to move synchronously, and the driving wheel 209h drives the groove wheel 209k rotates, and then the scraper 209l is driven to rotate through the cooperation of the groove wheel 209k and the driven shaft 209j, so that the scraper 209l cleans the particles attached to the surface of the blocking plate 105. When the driving wheel 209h rotates out of the groove of the groove wheel 209k, the brake wheel 209i limits the groove wheel 209k to prevent the groove wheel 209k from continuing to rotate due to inertia, so as to achieve the effect of intermittently cleaning the particles attached to the surface of the blocking plate 105 during the cleaning process.

[0043] In summary, through the coordination between the various components in the swing mechanism 200, the suction head 104 can perform reciprocating motion of corresponding strokes according to the different shapes and positions of the workpiece. The cleaning component 209 drives the scraper 209l to intermittently clean the blocking plate 105, which can prevent particulate matter from accumulating on the blocking plate and reduce the risk of blockage, so as to ensure full coverage of the cleaning area, improve the cleaning efficiency, and avoid the scraper 209l rotating too fast to affect the performance and efficiency of the equipment.
