[0021] Furthermore, the cross-section of the pressing roller 23 is an I-shaped structure that can fit with the aluminum component, making it easy to press the aluminum component.

[0022] Furthermore, the pressure roller 23 at the feeding end is a rubber roller, which is used to guide and convey the aluminum component, while preventing the aluminum component from being deformed due to protrusions on the surface of the aluminum component. The pressure roller 23 at the unloading end is a metal roller, which is used to level the polished aluminum component.

[0023] Furthermore, the detection device includes a top plate 31 installed on the upper side of the roller conveyor 1, and elastic columns 3 connected to the side of the roller conveyor 1 are provided at both ends of the bottom of the top plate 31. The elastic column 3 is a telescopic rod structure with a spring inside. A detection roller 32 is provided in the middle of the lower surface of the top plate 31, and the bottom of the detection roller 32 contacts the upper surface of the aluminum component. A distance sensor 33 for detecting the height of the top plate 31 is provided on the side of the roller conveyor 1; when the surface of the aluminum component is flat, or the depressions and protrusions are small, after the defective part of the aluminum component touches the detection roller 32, the distance sensor 33 detects that the detection roller 32 drives the top plate 31 to move up and down less; when there is a large protrusion on the surface of the aluminum component, after the defective part of the aluminum component touches the detection roller 32, the distance sensor 33 detects that the detection roller 32 drives the top plate 31 to move up and down more.

[0025] Furthermore, the moving part includes a base frame 5, a lead screw 61 is rotatably arranged in the middle of the base frame 5, and a driving motor 6 for driving the lead screw 61 to rotate is arranged at one end of the base frame 5, a nut seat 62 is threadedly connected to the driving motor 6, and a caster in contact with the base frame 5 is arranged on the side of the nut seat 62, a proximity sensor 51 is arranged on the upper surface of the base frame 5 near the end of the roller conveyor 1, and a lifting assembly is arranged on the upper surface of the nut seat 62, and the driving motor 6 drives the lead screw 61 to rotate, and the nut seat 62 moves during the rotation of the lead screw 61.

[0026] Furthermore, the lifting assembly includes a servo motor 7, a reducer 71 and a screw 72. The output shaft of the servo motor 7 is connected to the input end of the reducer 71, and the output shaft of the reducer 71 is connected to the screw 72 through a coupling. The reducer 71 is installed on the nut seat 62. The side of the screw 72 is threadedly connected with a lifting seat 73 for installing the polishing piece. A guide rod 8 is movably inserted into the lifting seat 73. The bottom of the guide rod 8 is connected to the housing of the reducer 71. A connecting plate 81 is provided on the upper surface of the guide rod 8, and the top of the screw 72 movably penetrates the connecting plate 81. The servo motor 7 drives the screw 72 to rotate through the reducer 71. When the screw 72 rotates, the lifting seat 73 moves up or down along the guide rod 8. The lifting seat 73 drives the polishing wheel 91 to move up or down through the polishing motor 9, thereby adjusting the height of the polishing wheel 91.

[0027] Furthermore, the polishing member includes a polishing motor 9 mounted on the lifting seat 73 , and a polishing wheel 91 is provided on the output shaft of the polishing motor 9 . The polishing motor 9 drives the polishing wheel 91 to polish and grind the surface of the aluminum component.

[0028] The roller conveyor 1, distance measuring sensor 33, proximity sensor 51, drive motor 6, servo motor 7 and polishing motor 9 used in the present invention are all commonly used electrical equipment in the prior art. Their working methods and circuit structures are all well-known technologies and are not elaborated here. The roller conveyor 1, distance measuring sensor 33, proximity sensor 51, drive motor 6, servo motor 7 and polishing motor 9 are all electrically connected to the external controller.

[0029] When using: 1. Place the square strip-shaped aluminum component for support on the roller conveyor 1, and control the roller conveyor 1 to work, so that the roller conveyor 1 conveys the aluminum component; 2. When the aluminum component passes through the roller pressing part at the feeding end, the rubber pressing roller 23 guides and presses the aluminum component; 3. There are two situations when aluminum components pass through the detection device: 31. When the surface of the aluminum component is flat, or the depressions and protrusions are small, after the defective part of the aluminum component touches the detection roller 32, the distance sensor 33 detects that the detection roller 32 drives the top plate 31 to move up and down slightly. At this time, the moving part does not work, and the polishing motor 9 drives the polishing wheel 91 to polish the part where the aluminum component passes; 32. When there is a large protrusion on the surface of the aluminum component, after the defect of the aluminum component touches the detection roller 32, the distance sensor 33 detects that the detection roller 32 drives the top plate 31 to move up and down to a large extent. At this time, the distance sensor 33 transmits a signal to the external controller, and the controller controls the drive motor 6 and the servo motor 7 to work: 321. The servo motor 7 drives the screw 72 to rotate through the reducer 71. When the screw 72 rotates, the lifting seat 73 moves up along the guide rod 8 by one end distance. The lifting seat 73 drives the polishing wheel 91 to move up by one end distance through the polishing motor 9. 322. The driving motor 6 drives the lead screw 61 to rotate, and the nut seat 62 moves along the lead screw 61. In this process, the nut seat 62 indirectly drives the polishing wheel 91 to move horizontally; 323. The servo motor 7 rotates in the opposite direction and causes the polishing wheel 91 to slowly move downward. During the downward and horizontal movement of the polishing wheel 91, the polishing wheel 91 and the aluminum component have the same horizontal movement speed. During the downward movement of the polishing wheel 91, the polishing motor 9 drives the polishing wheel 91 to polish and grind the protrusions on the surface of the aluminum component. 324. When the nut seat 62 moves to the proximity sensor 51, the controller controls the driving motor 6 to rotate in the opposite direction, so that the horizontal movement direction of the polishing wheel 91 is opposite to the horizontal movement direction of the aluminum component. During this process, the polishing wheel 91 continuously polishes the surface of the aluminum component to make its surface flat until the polishing wheel 91 moves to the horizontal initial position; 4. When the polished aluminum component passes through the pressure roller 23 at the unloading end, the metal pressure roller 23 cooperates with the roller conveyor 1 to level the entire aluminum component.

[0030] The present invention can detect the surface of the aluminum component during its transportation and polish the surface. The polishing effect is good, and no manual detection is required. The detection is comprehensive, manpower can be saved, and work efficiency is improved. The surface smoothness of the aluminum component can be effectively improved, and the operation is simple and easy to use.
