A connecting rod 10 is connected to the bottom of the No. 1 motor 9. A drive gear 11 is fixedly installed at the bottom end of the connecting rod 10. A transmission gear 12 is connected to the outer wall of the drive gear 11. A transmission rod 45 is fixedly installed on the inner wall of the transmission gear 12. A rotating wheel 46 is fixedly installed on the left side of the outer wall of the transmission rod 45. A grinding steel wire 47 is fixedly installed on the outer wall of the rotating wheel 46. A stabilizing sleeve rod 48 is connected to the left side of the rotating wheel 46. A No. 1 liquid pool 13 is fixedly installed at the bottom of the No. 1 treatment chamber 2. A second liquid tank 14 is fixedly installed at the bottom of the second processing chamber 8. A top plate 15 is installed in front of the second liquid tank 14. A first air pump 16 is fixedly installed on the top of the top plate 15. An air guide pipe 17 is fixedly installed on the outer wall of the first air pump 16. An outer frame plate 18 is fixedly installed at the bottom of the top plate 15. A paint spraying chamber 22 is installed on the left side of the conveyor belt 1. A protective curtain 23 is installed on the inner wall of the paint spraying chamber 22. An electric heating wire is fixedly installed on the inner wall of the outer frame plate 18. 19. A No. 3 treatment chamber 20 is fixedly installed at the bottom of the outer frame plate 18. A No. 2 nozzle 21 is fixedly installed on the inner wall of the No. 3 treatment chamber 20.

A rangefinder 53 is fixedly installed in the middle part of the movable box 52.

[0019] The above technical solution involves first inserting the automotive parts into the clamp, then starting the conveyor belt 1 to move the clamp and automotive parts together. Simultaneously, pumps 3 and 5 are activated, drawing in rust remover and degreaser through the rust remover pipe 4 and degreaser pipe 6. The rust remover and degreaser are then sprayed out through nozzle 7, removing oil stains and dissolving rust from the surface of the automotive parts. Next, motor 9 is activated, driving connecting rod 10 to rotate. Since a drive gear 11 is fixedly installed at the bottom of connecting rod 10, it can further... The drive gear 11 drives the transmission gear 12 to rotate. Since the transmission gear 12 is fixed to the transmission rod 45, it further drives the rotating wheel 46 to rotate synchronously. The rotating wheel 46, in conjunction with the polishing wire 47, powerfully cleans stains and rust from the surface of automotive parts.

In addition to removing rust from the surface of the automotive parts, the parts are continuously moved into the No. 3 processing chamber 20. The No. 1 air pump 16 is turned on to extract outside air, which is then directly heated by the heating wire 19. The hot air is then sprayed out through the No. 2 nozzle 21, thereby rapidly evaporating water stains on the surface of the automotive parts by increasing the temperature and accelerating the airflow. At the same time, the drive gear 49 is activated, which drives the transmission belt 50 to rotate. The transmission belt 50 drives the movable box 52 to move longitudinally, and the movable box 52 is held at a certain distance from the top of the workpiece by the rangefinder 53. Then, the No. 2 nozzle 21 at the bottom of the movable box 52 provides auxiliary air jet heating, thereby achieving the effect of evaporating water vapor, thus completing the pretreatment. Then, the paint spraying components inside the paint spraying chamber 22 spray the surface of the automotive parts. This device can automatically and quickly perform rust and dirt removal pretreatment on the surface of automotive parts. Its automatic batch processing method can quickly process a large number of automotive parts surface stains, avoiding the stains from affecting the paint spraying and protective treatment operation. It has excellent practical effect.

[0020] In this embodiment, as Figure 1 , Figure 4 , Figure 5 and Figure 6A connecting plate 24 is installed at the front of the conveyor belt 1.

A sampling chamber 29 is fixedly installed at the front of the connecting plate 24. An opening and closing plate 30 is movably installed on the top of the sampling chamber 29. A sand pump 31 is fixedly installed on the front of the inner wall of the sampling chamber 29. A guide pipe 32 is fixedly installed at the bottom of the sand pump 31 for sand pumping. A third nozzle 33 is installed on the outer wall of pump 31, and an overlap plate 34 is installed on the outer wall of conduit 32. A guide plate 35 is fixedly installed on the bottom of the inner wall of sampling chamber 29, and a heating plate 36 is fixedly installed on the top of guide plate 35. Fine sand 37 is installed on the bottom of the interior of sampling chamber 29, and a lamp tube 38 is fixedly installed on the top of the inner wall of sampling chamber 29. A monitoring head 39 is installed on the left side of lamp tube 38, and a second air pump 40 is installed around the monitoring head 39. A display screen 41 is fixedly installed on the back of the outer wall of sampling chamber 29. A controller 42 is fixedly installed at the bottom of the sampling chamber 29. An embedded panel 43 is movably installed on the left side of the outer wall of the sampling chamber 29. A viewing glass panel 44 is fixedly installed in the middle of the embedded panel 43. A trapezoidal plate 54 is fixedly installed in the middle of the overlapping plate 34. A telescopic push rod 55 is fixedly installed in the middle of the trapezoidal plate 54. A rotary motor 56 is fixedly installed on the top of the telescopic push rod 55. A receiving plate 57 is provided on the top of the rotary motor 56. An air inlet pipe 58 is provided at the bottom of the rear end of the inner side of the sampling chamber 29. A head airbag cushion 59 is fixed at the end of the air inlet pipe 58. The inner part of the pad 59 is provided with a connecting pipe 60, and a solenoid valve 61 is fixed on the outer wall of the connecting pipe 60. An air guide valve 62 is fixed at the end of the first airbag pad 59. A piston plate 63 is attached to the inside of the air guide valve 62. A limit spring 64 is fixed on the outer wall of the piston plate 63. An overlapping airbag pad 65 is provided at the end of the air guide valve 62. A tail airbag pad 66 is provided at the end of the overlapping airbag pad 65. A connecting pipe 67 is provided at the end of the tail airbag pad 66. A compression airbag 68 is provided at the end of the connecting pipe 67. A pressure sensor 69 is provided around the compression airbag 68.

[0021] Using the above technical solution, the first telescopic rod 26 is activated, causing the clamp 28 to move downwards. The clamp 28 then holds the automotive parts. The first telescopic rod 26 is then reset and extended. The second motor 25 is activated, causing the first telescopic rod 26 to rotate, thus aligning the clamp 28 with the opening and closing plate 30. The automotive parts are then placed inside the sampling chamber 29. The heating plate 36 is energized to heat the fine sand 37. The sand pump 31 and the conduit 32 are then activated to draw in the fine sand 37. The fine sand 37 is then sprayed out at high speed through the third nozzle 33, thereby conducting a high-temperature wear test on the surface of the automotive parts using the fine sand 37. Because the fine sand 37 contains corrosive substances, it can simultaneously... The automotive parts undergo corrosion testing. Fine sand 37 leaks downwards through the overlapping plate 34 and is guided to the duct 32 by the ramp of the guide plate 35, thus completing the recycling of the fine sand 37. After the test, the telescopic push rod 55 is activated and extended, causing the telescopic push rod 55 to drive the rotary motor 56 upwards. The rotary motor 56 also drives the receiving plate 57 to rotate, causing the fine sand 37 remaining on the receiving plate 57 to flow down. The second air pump 40 is activated and blows away the fine sand 37 on the surface of the automotive parts through the third nozzle 33. It can also blow away the fine sand 37 remaining in the third nozzle 33. The second air pump 40 can also supply air to the front airbag cushion 59 through the air intake pipe 58. When the first airbag cushion 59 is ventilated, it inflates, lifting the vehicle components. When the first airbag cushion 59 inflates to a certain size, it pushes the piston plate 63 connected to the limit spring 64. The piston plate 63 pushes back, opening the air valve 62, which connects the first airbag cushion 59 and the overlapping airbag cushion 65. The overlapping airbag cushion 65 then inflates, similar to the first airbag cushion 59. After the overlapping airbag cushion 65 inflates to a certain size, the next overlapping airbag cushion 65 also inflates. Once the last airbag cushion 66 inflates, the compression airbag 68 is inflated through the guide tube 67. The inflated compression airbag 68 then presses against the pressure sensor 69, compressing... When the force sensor 69 is compressed, the internal controller controls the solenoid valve 61 to release the air inside the front airbag 59, the overlapping airbag 65, and the rear airbag 66. The front airbag 59, the overlapping airbag 65, and the rear airbag 66 can lift the automotive parts through the above cycle, so that the automotive parts can be tested more evenly. In addition, the monitoring head 39 takes pictures of the surface of the automotive parts and displays them on the display screen 41, so that the staff can observe the wear of the automotive parts in real time. This device can automatically grab and extract automotive parts for inspection, so that the staff can know the effect of the protective treatment in time. It has excellent practical effect.

[0022] According to another aspect of the present invention, a method for protecting automotive parts is provided, comprising the following steps: S1: First, the surface of the automotive parts is cleaned in the No. 1 processing room; S2: The surface of the automotive parts is rinsed through the No. 2 processing chamber; S3: Dry the surface of the automotive parts through the No. 3 processing chamber; S4: The surface of the automotive parts is sprayed and dried through the spray booth; S5: Place the surface of the automotive parts inside the sampling inspection chamber and inspect them.

[0023] The working principle of this device is as follows: First, rust remover and degreaser are sprayed out through nozzle 7 to wash away oil stains on the surface of the car parts and dissolve rust. Then, motor 9 is started to drive the rotating wheel 46 to rotate, thereby causing the grinding wire 47 to scrub the rust on the surface of the car parts. Air pump 16 is turned on to draw in outside air, and then the air is directly heated by heating wire 19. The hot air is then sprayed out through nozzle 21 to accelerate the evaporation of water stains. Then, the paint spraying components inside the paint spraying chamber 22 spray the surface of the car parts. The car parts are held by clamp 28 and placed in the vacuum chamber. Inside laboratory 29, heating plate 36 is powered on to heat fine sand 37. Fine sand 37 is then sprayed out at high speed through nozzle 33, thus conducting a high-temperature wear test on the surface of the automotive parts. The fine sand 37 can also be leaked downwards through overlapping plate 34 and guided to duct 32 through the ramp of guide plate 35, thus completing the recycling of fine sand 37. After the test, air pump 40 is started and the fine sand 37 on the surface of the automotive parts is blown away through nozzle 33. At the same time, monitoring head 39 is used to take pictures of the surface of the automotive parts and the images are displayed on display screen 41, so that staff can easily observe the wear condition of the automotive parts.

[0024] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention are also within the protection scope of the present invention.
