[0050] There are two extension frames 16 provided, and the two extension frames 16 are located on the upper and lower sides of the swing arm 6. A number of drag reduction beads are rotatably arranged at the top and bottom of the swing arm 6, and the drag reduction beads are in contact with the inner walls of the extension frame 16 and / or the hinge holes 17.

[0051] The second driving mechanism includes a driving frame 18 arranged inside the lifting frame 4. A driving wheel 19 is horizontally rotatably arranged at the bottom of the driving frame 18. A driving part 20 is vertically arranged at the bottom of the driving wheel 19. The straight line where the driving part 20 is located is in a staggered state with the straight line where the axis of the driving wheel 19 is located. A long strip-shaped driving groove 21 is vertically formed through the swing arm 6. The driving part 20 is movably in contact with the inner wall of the driving groove 21. A third driving mechanism for rotating the driving wheel 19 is arranged on the lifting frame 4.

[0052] The third driving mechanism includes a convex seat 23 arranged inside the lifting frame 4. The driving frame 18 is connected to the inner side of the convex seat 23. A cylindrical rotating space 24 is horizontally formed in the convex seat 23. A long strip-shaped flowing space 25 is horizontally formed in the lifting frame. The flowing space 25 communicates with one side of the rotating space 24. A transmission column 26 is vertically arranged on the convex seat 23. A transmission wheel 27 is arranged at the bottom of the transmission column 26. The transmission wheel 27 meshes or abuts against the driving wheel 19. A number of transmission vanes 28 are arranged on the outer wall of the top of the transmission column 26 in a uniformly divergent manner. The upper and lower sides of the transmission vanes 28 are movably in contact with the inner wall of the rotating space 24. The free ends of the transmission vanes 28 are movably in contact with the inner wall of the rotating space 24 or are located in the flowing space 25. One end of the flowing space 25 is connected and provided with a third air inlet pipe 29. The first air inlet pipe 8 communicates with the other end of the flowing space 25. The end of the third air inlet pipe 29 away from the flowing space 25 communicates with the air supply pipe 10. When air flows from the third air inlet pipe 29 towards the first air inlet pipe 8, the driving part 20 can drive the transmission vanes 28 to rotate.

[0053] A concentrating seat 30 is arranged on the side of the flowing space 25 away from the rotating space 24. An arc-shaped concentrating groove 31 is formed on the side of the concentrating seat 30 close to the rotating space 24. The free ends of the transmission vanes 28 can be in contact with the inner wall of the concentrating groove 31.

[0054] The output end of the air supply pipe 10 is connected and provided with a distribution cavity 32. All the second air inlet pipes 13 and the third air inlet pipes 29 communicate with the distribution cavity 32.

[0055] A surface cleaning system for automobile bumper production provided by the present invention. When the conveyor 2 (preferably a conveyor belt, and the support frame 1 is provided with rollers for supporting the conveyor belt and motors for driving the rollers to rotate. At the same time, there can also be multiple rods or plates passing through the middle of the conveyor belt in the middle of the support frame 1 to improve the shape stability of the conveyor belt) sends the bumper below the lifting frame 4, the first driving mechanism slowly lowers the height of the lifting frame 4. At the same time, the air supply pump 9 (a conventional air pump, such as an air compressor) injects compressed air into the inner wall of the cleaning column 5 through the air supply pipe 10 and the first intake pipe 8, so that the compressed air is ejected outward through multiple cleaning heads 7 (with a small opening and a relatively dense distribution to ensure the air flow speed and the action range). At the same time, the second driving mechanism drives the swing arm 6 and the cleaning column 5 to swing. In this way, the whole effect is that the high-speed air ejected by the cleaning heads 7 acts on the surface of the bumper, and at the same time its height drops and it swings left and right, so that the bumper can be better cleaned of dust. At this time, the four cleaning columns 5 simultaneously blow dust on the four sides of the bumper to ensure the cleaning effect. At the same time, when the cleaning column 5 is at a relatively high height, it can also clean the top of the bumper, ensuring the overall cleaning effect. The shape of the bumper is not a flat shape, but a special shape with grooves and / or protrusions and / or holes. Therefore, when the cleaning column 5 swings left and right, it not only ensures a wider cleaning surface, but also can clean the places that are difficult to clean in the special shape, with higher cleaning quality, which ensures the quality of production from the side.

[0056] During the actual cleaning process, there is a protrusion on the conveyor 2 on each side of the bumper. At the same time, a position sensor or an infrared sensor is connected to the cleaning frame 3. When the protrusion moves to the sensor position, it means that the bumper (there is a frame on the conveyor 2 for placing the bumper to ensure the position of the bumper) moves below the lifting frame 4. Then at this time, the air supply pump 9 is automatically started or the electric control valve on the air supply pipe 10 is automatically opened, so that the compressed air enters the distribution cavity 32 through the air supply pipe 10, and the compressed air also enters the second intake pipe 13 and the third intake pipe 29.

[0057] The compressed air in the second intake pipe 13 enters the guide cylinder 11 and drives the piston part 12b downward (which is relatively sealed with the inner wall of the guide cylinder 11). By controlling the diameter of the second intake pipe 13, the diameter of the piston part 12b, etc. and the elastic force of the elastic member 14, the piston part 12b descends at a relatively suitable slow speed at this time. During the slow downward movement of the lifting frame 4, the compressed air in the third intake pipe 29 enters the first intake pipe 8 through the flow space 25, enters the cavity-shaped cleaning column 5, and is ejected outward through the cleaning heads 7.

[0058] During the process of the compressed air flowing in the flow space 25, since the transmission blade 28 is located between the outflow end of the third intake pipe 29 and the inflow end of the first intake pipe 8, the flowing air can drive part of the transmission blade 28 to rotate, thereby driving the transmission column 26 and the transmission wheel 27 to rotate. At the same time, the transmission wheel 27 drives the driving wheel 19 to rotate. After the driving wheel 19 acts on the inner wall of the driving groove 21 through the driving part 20 during rotation, the swing arm 6 swings reciprocally. Thus, the movement mode of the entire cleaning column 5 is to swing reciprocally while descending, and blow dust off the bumper.

[0059] When the cleaning column 5 moves to the lowest height, the air supply pump 9 stops operating or the electric control valve on the air supply pipe 10 closes. Then, under the elastic force of the elastic member 14, the lifting frame 4 rises and resets, waiting for the next use. According to the actual situation, a pipe body with a solenoid valve can also be connected to the distribution cavity 32. During the cleaning process, the solenoid valve keeps the pipe body in a closed state; after the cleaning is completed, the solenoid valve opens, and external air enters the distribution cavity 32, so that the inside of the guide cylinder 11 communicates with the outside. At this time, the lifting frame 4 can also rise.

[0060] When the compressed air flows in the flow space 25, the concentrating seat 30 and the concentrating groove 31 enable the air to better act on the transmission blade 28 in the flow space 25, ensuring the rotational power of the transmission column 26. At the same time, in this application, covers are installed at all places where the transmission wheel 27 is installed. That is, when installing each structure, the cover needs to be removed first. Then, after each structure is installed in the rotation space 24 and the flow space 25, the cover is hermetically installed on the lifting frame 4. At the same time, when the swing arm 6 rotates to the maximum angle, its side will touch the inner wall of the hinge hole 17. In this way, the inertial action of the cleaning column 5 etc. can be offset by the inner wall of the hinge hole 17, enabling it to swing reciprocally conveniently and smoothly; and during its swinging process, the resistance-reducing beads can greatly reduce the moving resistance. It should also be understood that all the pipelines in this application are flexible and have sufficient length. The lengths and shapes in the drawings are only for illustration and do not represent the actual structure and proportion.

[0061] It should also be supplemented and explained that all "settings" and similar descriptive words in this application (especially in the specification) express that there is a connection relationship between two structures, but the specific means of connection between the two are not overly limited, and usually are conventional connection means, that is, it should be understood that such means are prior art and do not need to be elaborated. For example, "n is provided on m" only expresses that there is an n structure on the m structure, and whether the two are connected by welding, riveting, adhesive bonding or integrally formed are all within the protection scope of this application; another example is "y is rotatably provided on x", which only expresses that y and x can rotate relative to each other, and as for whether the two are rotatably connected by a bearing, or y directly passes through x and is rotatably connected to x, or other achievable ways, they are all within the protection scope of this application.

[0062] The above description is only a description of the preferred embodiments of the present invention and does not limit the scope of the present invention in any way. Any changes and modifications made by those of ordinary skill in the art of the present invention based on the above disclosure are within the protection scope of the claims.
