A collecting bin 1310 is clamped on the rear side of the bottom of the housing 133. The collecting bin 1310 can collect the scraped smoke and dust powder. A closed The closing component can realize the closure of the shell 133; the closing component includes a return frame 134, a swing plate 135 and a torsion spring 1351. The return frame 134 is fixedly connected to the left side of the box body 1, and the return frame 134 is connected to the shell 133. The swing plate 135 is evenly spaced and rotatably connected between the front and rear sides of the return frame 134. The swing plate 135 can realize the closure of the shell 133, and a torsion spring 1351 is connected between the swing plate 135 and the return frame 134.

[0035] First, press the control panel 2 to control the electric lifting plate 3 to move upward through the control module. The electric lifting plate 3 stops moving upward to block the opening of the box 1, and the wheel hub can be placed in the box 1 to contact the electric rotating disk 4. Then start the electric clamp 41 to fix the car wheel hub, start the electric lifting plate 3 to move downward to reset and block the opening of the box 1, and then start the first rodless cylinder 8 to drive the lifting frame 7 to move forward. The lifting frame 7 moves forward to drive the movable frame 6 and the laser head 12 to move forward. When the laser head 12 moves forward to correspond to the car wheel hub, turn off the first rodless cylinder 8, and the laser head 12 stops moving forward. Then, press the control panel 2 to control the one-line laser light 10 to start through the control module. The one-line laser light 10 irradiates the laser on the car wheel hub. The laser is reflected on the distance measuring module 11, and the distance measuring module 11 calculates the distance between the laser head 12 and the automobile wheel hub. The distance measuring module 11 controls the second rodless cylinder 9 to start through the control module. The second rodless cylinder 9 starts to drive the first rodless cylinder 8 to move up and down, and the first rodless cylinder 8 drives the lifting frame 7 to move up and down. The lifting frame 7 moves up and down to drive the laser head 12 to move up and down. When the laser head 12 moves up and down to a suitable position for laser stripping of the automobile wheel hub, the second rodless cylinder 9 is turned off, and the laser head 12 stops moving up and down. The laser irradiated by the laser head 12 is slightly defocused, which expands the laser processing spot and reduces the concentration of laser energy, so that the laser energy can be more dispersed to process the paint layer of the automobile wheel hub, and at the same time does not affect the paint surface. The absorption rate of the laser can make the paint layer on the outer surface of the automobile wheel hub evaporate due to heat without damaging the workpiece substrate, thus overcoming the problem that the laser paint stripping process is prone to produce etching shading. Subsequently, the laser head 12 is started, and the laser head 12 irradiates the laser to perform laser paint stripping on the automobile wheel hub. At the same time, the first rodless cylinder 8 is started again to drive the lifting frame 7 to move forward, and the lifting frame 7 drives the movable frame 6 and the laser head 12 to move forward. The laser head 12 moves forward to continue laser paint stripping on the outer surface of the automobile wheel hub. The movable frame 6 drives the distance measuring module 11 to move forward, and the distance measuring module 11 moves forward to continue calculating the distance between the laser head 12 and the automobile wheel hub. Whenever the laser head 12 moves to correspond to the concave and convex part of the automobile wheel hub, the energy of the laser changes, and the laser head 1 2 and the wheel hub of the automobile also changes. At this time, the laser head 12 needs to move so that the energy of the laser is restored to the required state. The ranging module 11 controls the second rodless cylinder 9 to operate through the control module, so that the lifting frame 7 drives the laser head 12 to move downward. When the laser head 12 moves downward so that the energy of the laser is dispersed to process the paint layer of the paint-stripped part, the second rodless cylinder 9 is closed, and then the laser head 12 continues to move forward to laser strip the paint on the outer surface of the automobile wheel hub. This is repeated, so that the position of the laser head 12 can be flexibly moved along with the concave and convex parts of the wheel hub surface, so as to ensure that the laser can laser strip the paint on the outer surface of the automobile wheel hub with a slight defocus to expand the light spot, reduce the influence of the laser etching background, and thus improve the effect of laser stripping.At the same time, the control panel 2 is pressed to control the drive motor 136 to rotate forward through the control module. The drive motor 136 rotates forward through the synchronous belt assembly to drive the rotating shaft 131 to rotate forward. The rotating shaft 131 rotates forward through the synchronous belt assembly to drive the rotating frame 137 to rotate forward. The rotating frame 137 rotates forward to drive the spiral scraper 138 to rotate forward. At the same time, the forward rotation of the rotating shaft 131 also drives the rotating blades 132 to rotate forward. The rotating blades 132 rotate forward to draw the outside air into the exhaust frame 13. The exhaust frame 13 exhausts the air into the box body 1, so that the air is blown to the left. The flowing air contacts the swing plate 135. The air pushes the swing plate 135 to swing upward. The torsion spring 1351 is compressed, and the swing plate 135 stops swinging upward to seal the shell 133. The air continues to flow and is discharged into the shell 133. The smoke and dust powder produced by the laser paint stripping is blown to the left through the return frame 134 and discharged into the shell 133. The smoke and dust powder in the shell 133 contacts the cylinder 139, and the cylinder 139 blocks the smoke and dust powder. The spiral scraper 138 rotates forward to remove the smoke and dust powder attached to the outer wall of the cylinder 139. The removed smoke and dust powder moves backward with the forward rotation of the spiral scraper 138. When the smoke and dust powder moves backward to the top of the collection bin 1310, the smoke and dust powder falls into the collection bin 1310 and is collected. In this way, the residual smoke and dust powder can be prevented from affecting the working environment, thereby ensuring a good working environment. When the laser head 12 moves forward to the maximum stroke, the first rodless cylinder 8 stops passing through the lifting The lowering frame 7 drives the laser head 12 to move forward, and the electric rotating disk 4 is started to rotate to drive the electric clamp 41 to rotate. The rotation of the electric clamp 41 drives the car wheel hub to rotate, so that the lower part of the car wheel hub rotates to the paint stripping area. The electric rotating disk 4 stops and drives the car wheel hub to rotate through the electric clamp 41. Then the first rodless cylinder 8 drives the lifting frame 7 to move backward, and the lifting frame 7 drives the laser head 12 to move backward to continue laser stripping the car wheel hub. When the laser stripping of the outer surface of the car wheel hub is completed, the laser head 12 is turned off and moved backward to reset. At the same time, the straight line laser light 10 is turned off, and then the control panel 2 is pressed to control the electric lifting plate 3 to move upward to a suitable position through the control module, and the electric clamp 41 is started to release the car wheel hub. , At the same time, press the control panel 2 to control the drive motor 136 to turn off through the control module, the drive motor 136 stops driving the shaft 131 to rotate forward, the shaft 131 stops driving the rotating blades 132 to rotate forward, and the rotating blades 132 stop pumping air into the exhaust frame 13. Due to the action of the torsion spring 1351, the swing plate 135 swings downward to reset and seal the shell 133 to prevent the dust in the shell 133 from floating back into the box 1 and attaching to the car wheel hub. At the same time, the rotating frame 137 stops driving the spiral scraper 138 to rotate forward, and the car wheel hub can be taken out from the box 1, and then the collection bin 1310 is removed from the shell 133 to pour out the smoke and dust powder. After all the smoke and dust powder is poured out, the collection bin 1310 is clamped back to the discharge end of the shell 133. ,

A rotating assembly is arranged on the box body 1, and when the rotating assembly is in operation, the rotating assembly can drive the first wiping roller 142 and the second wiping roller 144 to rotate; the rotating assembly includes a U-shaped plate 146, a rotating rod 1461, a spur gear 147 and an electric gear 148, and a U-shaped plate 146, U-shaped plate 146 is fixedly connected to the rear side of guide tube 145, left and right sides of U-shaped plate 146 are rotatably connected with rotating rods 1461, the left and right rotating rods 1461 are respectively connected to the left and right sides of the first wiping roller 142 through a synchronous belt assembly, the ends of the left and right rotating rods 1461 are respectively connected to the left and right second wiping rollers 144 through a bevel gear assembly, the rear sides of the left and right second wiping rollers 144 are fixedly sleeved with spur gears 147, an electric gear 148 is installed on the upper part of the outer rear side of the box body 1, the electric gear 148 is meshed with the left and right spur gears 147, and the electric gear 148 is electrically connected to the control panel 2.

[0037] Initially, the guide pipe 145 is externally connected to a machine for discharging alcohol and a discharge pipe 143 is externally connected to a collecting container. When the first rodless cylinder 8 is started, the lifting frame 7 drives the laser head 12 to move forward, and the laser head 12 moves forward and disengages from the first wiping roller 142. At the same time, the movable frame 6 drives the distance measuring module 11 to move forward and disengage from the second wiping roller 144. When the laser stripping of the exterior surface of the automobile wheel hub is completed, the lifting frame 7 drives the laser head 12 to move backward and reset to contact the first wiping roller 142, and the movable frame 6 drives the distance measuring module 11 to move backward and reset to contact the second wiping roller 144. At this time, the external alcohol is discharged from the right side into the guide pipe 145, and the alcohol is sprayed onto the first wiping roller 142 and the second wiping roller 144 through the liquid outlet of the guide pipe 145. Then, the control panel 2 is pressed to start the electric gear 148 through the control module to rotate and drive the spur gear 147 to rotate.

The discharge pipe 143 discharges the waste liquid into an external collection container for collection. When the impurities attached to the ranging module 11 and the laser head 12 are cleaned up, stop discharging water into the guide pipe 145, and then turn off the electric gear 148. The electric gear 148 stops driving the spur gear 147 to rotate, and the spur gear 147 stops driving the second wiping roller 144 to rotate, and the second wiping roller 144 also stops rotating. In this way, it is possible to prevent impurities from being attached to the distance measuring module 11 and the laser head 12 to affect the subsequent use effect, thereby ensuring the normal use of the distance measuring module 11 and the laser head 12.

[0038] See also Fig.11 As shown, the laser paint stripping device for the outer surface of the automobile hub also includes a transparent plate 15, and the transparent plate 15 is fixedly connected to the middle part of the electric lifting plate 3.

[0039] When the outer surface of the automobile wheel hub is being laser stripped, the operator can view the laser stripping status of the outer surface of the automobile wheel hub through the transparent plate 15, so that corresponding processing can be performed according to the laser stripping status of the outer surface of the automobile wheel hub, so that the automobile wheel hub can be adjusted in time.
