Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0030] Referring to Figures 1 to 3 , according to an embodiment of the present utility model, the wheel pair laser cleaning device 100 includes a laser module 101 and a base 102. The laser module 101 includes a cleaning module 202, and the cleaning module 202 includes a laser head 301, a first air knife 302, and a second air knife 303. The base 102 is disposed at intervals below the laser module 101, and the base 102 is used to place the workpiece 104. The workpiece 104 includes a cleaning surface 110. The laser head 301 is used to emit laser light toward the cleaning surface 110. The first air knife 302 is used to provide a first air flow blowing toward the cleaning surface 110. One end of the laser head 301 that emits laser light is an emission end 308. The second air knife 303 is used to provide a second air flow covering the emission end 308. The first air flow provided by the first air knife 302 blows toward the cleaning surface 110, reducing the accumulation of dust and the influence of dust on the laser. The second air knife 303 provides a second air flow covering the emission end 308, preventing the contamination of the laser head 301 by dust during the laser cleaning process, thereby improving the laser processing effect.

[0031] Referring to Figure 3 , in some embodiments of the present utility model, the first air knife 302 is disposed on the side of the laser head 301. The direction in which the first air knife 302 emits the first air flow is the first direction, and the direction in which the laser head 301 emits laser light is the second direction. The first direction intersects the second direction and the included angle is an acute angle. The included angle being an acute angle can enable the first air flow to better interfere with the end of the laser emission path, thereby purging the dust in the laser processing path and improving the laser cleaning effect. Preferably, in some embodiments of the present utility model, the first air flow is set to blow toward the cleaning surface 110, so that the accumulation of dust on the cleaning surface 110 can be better processed, further improving the cleaning effect.

[0032] Referring to Figure 3, in some embodiments of the present utility model, the second air knife 303 is annular, the second air knife 303 surrounds the ejection end 308, and the air outlet of the second air knife 303 is located on the inner circumferential surface of the second air knife 303 and faces the central axis of the second air knife 303. In this way, a wind barrier covering the ejection end 308 can be formed, thereby blocking dust from blowing towards precision components such as the optical lens inside the laser head 301 through the ejection end 308, effectively protecting the laser head 301, improving the service life of the laser head 301, and moreover, the air flow direction of the annular air knife is from outside to inside, and the influence range is also smaller compared to that of a linear air knife, which can effectively reduce the influence of the formed wind barrier on other components while protecting the laser head 301. It should be noted that, in some embodiments of the present utility model, a unidirectional linear air knife or other structures can also be used and arranged at the ejection end 308 to provide a second air flow covering the ejection end 308.

[0033] Reference Figure 3 , in some embodiments of the present utility model, the cleaning module 202 further includes a dust suction component 306. The dust suction component 306 is installed on the side of the laser head 301. The dust suction component 306 includes a dust suction port, the orientation of the dust suction port is the third direction, the direction in which the laser head 301 emits laser is the second direction, the third direction intersects with the second direction and the included angle is an acute angle, and the dust suction port is used for sucking dust from the cleaning surface 110. The setting of the acute angle can enable the dust suction port to better suck the dust at the end of the laser emission path, that is, suck the dust at a position closer to the cleaning surface 110, improving the laser cleaning effect.

[0034] It should be noted that, reference Figure 3 , in some embodiments of the present utility model, the cleaning module 202 further includes a displacement sensor 307. The displacement sensor 307 is installed on the side of the laser head 301 and is used to detect the distance between the laser head 301 and the workpiece 104, so as to adjust the position of the laser head 301 to provide an optimal working state.

[0035] Reference Figure 1 and Figure 2 , in some embodiments of the present utility model, the wheel pair laser cleaning device 100 further includes a gantry 103. The gantry 103 further includes a cross beam 105. The laser module 101 is installed below the cross beam 105. The laser module 101 further includes a motion module 201. The motion module 201 is used to drive the cleaning module 202 to move relative to the gantry 103. The structure of the gantry 103 is stable, and the outer circumference, inner surface and interlayer of the gantry 103 can also provide placement and installation positions for many mechanisms. The space below the cross beam 105 can well provide a working space. The motion module 201 driving the cleaning module 202 to move relative to the gantry 103 can enable the cleaning module 202 to clean the workpiece 104 from multiple angles, improving the applicability of the wheel pair laser cleaning device 100.

[0036] It should be noted that with reference to Figure 1 , in some embodiments of the present utility model, the wheel set laser cleaning device 100 further includes a rolling shutter door 111, which is installed above the openings at both ends of the gantry 103. When the workpiece 104 is to be cleaned and processed inside the gantry 103, the rolling shutter door 111 is lowered to form a working space, thereby reducing the pollution of the external environment by the dust generated during work. Preferably, the rolling shutter door 111 is made of flame-retardant polyvinyl chloride, which can improve the safety performance and prevent sparks generated during work from splashing into the external environment and causing safety accidents.

[0037] It should be noted that in some embodiments of the present utility model, a panoramic camera is also installed in the working space. When the rolling shutter is lowered and the laser module 101 starts to work, the panoramic camera can capture the conditions inside the working space and feedback them to the external staff, enabling them to observe the cleaning situation and handle any abnormalities in a timely manner, thereby improving the safety performance.

[0038] It should be noted that in some embodiments of the present utility model, a movable dust extraction pipe is also installed below the cross beam 105. The dust suction assembly 306 is mainly used to suck the dust between the cleaning surface 110 and the laser head 301, while the movable dust extraction pipe can specifically suck the dust attached to the surface of the equipment or falling on the base 102 after the processing is completed, which can improve the cleanliness of the working environment and reduce dust accumulation.

[0039] With reference to Figure 2, in some embodiments of the present utility model, the motion module 201 includes a first linear transmission mechanism 203, a second linear transmission mechanism 204 and a rotation mechanism 205. The first linear transmission mechanism 203 includes a first track portion 206 and a first slider 207. The first slider 207 is slidably mounted on the first track portion 206, and the first track portion 206 is arranged in the horizontal direction. The second linear transmission mechanism 204 includes a second track portion 208 and a second slider 209. The second track portion 208 is fixed to the first slider 207, and the second slider 209 is slidably mounted on the second track portion 208. The second track portion 208 is arranged in the vertical direction. The rotation mechanism 205 includes a third track portion 304 and a third slider 305. The third track portion 304 is rotatably connected to the second slider 209. The third slider 305 is fixed to the cleaning module 202, and the third slider 305 is slidably mounted on the third track portion 304. The third track portion 304 is arc-shaped, and the two ends of the third track portion 304 are located in the same vertical plane. The cleaning module 202 can rotate relative to the third track portion 304 in the vertical direction to adjust the swing of the laser head 301 in the vertical direction; and the third track portion 304 is connected to the second slider 209, so that the rotation mechanism 205 can move in the vertical direction along the second track portion 208 to realize the position adjustment of the laser head 301 in the vertical direction. At the same time, the third track portion 304 is rotatably connected to the second slider 209, which can make the laser head 301 rotate along its own axis, so as to realize the large-angle adjustment in the vertical direction; and the second track portion 208 is fixed on the first slider 207, so that the second linear transmission mechanism 204 can move in the horizontal direction along the first track portion 206, so as to realize the position adjustment of the laser head 301 in the horizontal direction, so as to realize the movement of the laser head 301 in multiple directions and at multiple angles, so as to be able to clean the surface of the workpiece 104 at more angles and improve the laser cleaning effect. It should be noted that refer to Figure 3 , in some embodiments of the present utility model, the third track portion 304 is connected to the second slider 209 through a servo motor 309, so that the rotation of the third track portion 304 can adjust the angle and speed through the servo motor 309, and the applicability is wider.

[0040] Refer to Figure 1 and Figure 4, in some embodiments of the present utility model, the workpiece 104 includes a main shaft 106 and two wheels 107 symmetrically arranged at both ends of the main shaft 106. The wheel 107 includes a main body portion 108 and a rim portion 109. The rim portion 109 is disposed around the outer periphery of the main body portion 108 close to the main shaft 106, and the rim portion 109 protrudes relative to the outer peripheral surface of the main body portion 108. The base 102 includes two guide rails 401 arranged at intervals. The main body portion 108 is rollably placed on the guide rails 401. The guide rails 401 include abutting surfaces 403. The abutting surfaces 403 of the two guide rails 401 face each other. The abutting surface 403 is used to abut against the surface of the rim portion 109 away from the main shaft 106 to limit the movement of the workpiece 104 in the width direction of the guide rails 401. The abutment between the rim portion 109 and the guide rails 401 reduces the swing of the workpiece 104 when placed on the guide rails 401, and the arrangement of the guide rails 401 enables the workpiece 104 to roll smoothly into the gantry 103 for cleaning.

[0041] It should be noted that, with reference to Figure 1 , in some embodiments of the present utility model, the first linear drive mechanism 203 is consistent with the extending direction of the cross beam 105 on the gantry 103, and the direction of the interval arrangement of the guide rails 401 is also consistent with the extending direction of the first linear drive mechanism 203. In this way, the workpiece 104 placed on the guide rails 401 can be better cleaned and processed, and the cleaning of the workpiece 104 in the horizontal direction can be achieved with the smallest displacement.

[0042] With reference to Figure 4 , in some embodiments of the present utility model, grooves 402 are provided at the parts of the two guide rails 401 below the cross beam 105. The wheel pair laser cleaning device 100 further includes a driving member 404 and two pulley groups 405. The pulley group 405 includes a driving wheel 406 and a driven wheel 407. When the main body portion 108 is located at the groove 402, the outer peripheral surface of the rim portion 109 abuts against the driving wheel 406 and the driven wheel 407. The driving member 404 is used to drive the driving wheel 406 to rotate so that the workpiece 104 rotates around its own axis. The groove 402 can play a certain positioning role. When the workpiece 104 rolls along the guide rails 401 to the position of the groove 402, the main body portion 108 will fall into the groove 402, and the overall height of the workpiece 104 decreases. At this time, the rim portion 109 protruding relative to the main body portion 108 abuts against the driving wheel 406 and the driven wheel 407. When the driving wheel 406 rotates, the workpiece 104 will be subjected to friction and rotate. In this way, the workpiece 104 can face the laser module 101 with different surfaces, so as to realize the cleaning process of the outer peripheral surface of the workpiece 104 by using the self-rotation of the workpiece 104, making the laser cleaning more comprehensive.

[0043] It should be noted that, with reference to Figure 4In some embodiments of the utility model, the driving member 404 is a motor, and the driving wheel 406 between the two pulley groups 405 is connected by a driving shaft 409, and the driven wheel 407 is connected by a driven shaft 410. The motor drives the driving shaft 409 to rotate through a sprocket so that the driving wheels 406 at both ends rotate. The structure designed in this way is simple and easy to maintain, and only one output end is required to evenly drive the two ends to rotate.

[0044] It should be noted that the reference Figure 4 In some embodiments of the present invention, a reducer 411 is also installed between the motor and the driving shaft 409. Since the rotation of the driving wheel 406 is mainly to drive the workpiece 104 to rotate, and the workpiece 104 does not require a large rotation speed during the cleaning process, the reducer 411 can effectively reduce the high rotation speed output from the motor, so that the rotation of the workpiece 104 is smoother. At the same time, the reducer 411 can also increase the torque, thereby driving the workpiece 104 with a higher weight to rotate.

[0045] Preferably, reference Figure 4 In some embodiments of the present invention, the reducer 411 is of a right-angle turn type, which utilizes a worm gear transmission and has an adjustable speed. It has a lower cost than a direct-connection type, but a direct-connection type may also be used in consideration of different usage scenarios. Both types can realize the function of reducing the speed of the motor output end.

[0046] refer to Figure 4 , Figure 6 and Figure 7 In some embodiments of the present invention, the wheelset laser cleaning device 100 further includes an ejection mechanism 408, which is disposed between the two guide rails 401. The ejection mechanism 408 is used to abut the wheel rim 109 to disengage the main body 108 from the groove 402. The ejection mechanism 408 enables the workpiece 104 to smoothly disengage from the groove 402 after being processed, so as to continue to roll away from the gantry 103 along the guide rail 401. The ejection mechanism 408 is disposed inside the guide rail 401 and abuts against the wheel rim 109, so that the ejection mechanism 408 can be buried inside the base 102 to reduce the occupied space. Specifically, refer to Figure 4 In some embodiments of the present invention, the ejection mechanism 408 uses a telescopic cylinder. By setting a bump on the end face of the piston rod, the bump just abuts against the rim 109 after the cylinder is extended to exert an upward and forward force on the workpiece 104, so that the workpiece 104 can be smoothly separated from the groove 402. The upward oblique ejection also makes the separation of the workpiece 104 more convenient. In some embodiments of the present invention, a cylinder extending upward and a cylinder extending in the extension direction of the guide rail 401 can also be used to achieve the separation of the workpiece 104 from the groove 402.

[0047] refer to Figure 5, in some embodiments of the present utility model, a limiting block 501 is provided on the end face of the end of the guide rail 401 away from the cross beam 105. The limiting block 501 protrudes relative to the upper surface of the guide rail 401, and / or, guide plates 502 are provided on the sides of the ends of the two guide rails 401 away from the cross beam 105. The bottom end of the guide plate 502 is connected to the upper surface of the guide rail 401, the top end of the guide plate 502 extends upward, the guide plate 502 is inclined relative to the vertical plane, and the distance between the two guide plates 502 gradually decreases from top to bottom. The limiting block 501 can prevent the workpiece 104 from rolling off the track when placed on the guide rail 401, improving safety performance. The guide plate 502 can make the process of placing the workpiece 104 on the guide rail 401 more diverse. In the conventional technology, the workpiece 104 is pushed into the guide rail 401 flatly. However, after the guide plate 502 is provided, the workpiece 104 can be hoisted and placed on the guide rail 401 from top to bottom. The guide plate 502 plays a good guiding and abutting role on the two side edges of the workpiece 104, improving safety performance and the efficiency of the process of placing the workpiece 104.

[0048] It should be noted that with reference to Figure 5 , in some embodiments of the present utility model, a blocking mechanism 503 is further provided on the base 102. The blocking mechanism 503 can extend or descend relative to the upper surface of the guide rail 401 so as to abut against the workpiece 104. In this way, when the workpiece 104 is placed on the guide rail 401 for processing, the blocking mechanism 503 can be extended to limit the workpiece 104, avoiding the rolling of the workpiece 104 to be processed on the guide rail 401 and improving safety.

[0049] The embodiments of the present utility model have been described in detail above with reference to the drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art to which the present utility model pertains, various changes can be made without departing from the gist of the present utility model. In addition, the embodiments of the present utility model and the features in the embodiments can be combined with each other without conflict.
