However, due to production processes, environmental factors, or raw material issues, oxidized profiles may exhibit surface defects such as color variation, spots, scratches, and uneven film thickness. These defects not only affect the product's appearance but can also reduce its mechanical properties and durability.

Since the rotation directions of the first transmission gear 7 and the second transmission gear 802 are opposite, when the conveyor belt 502 is reversely transmitted, the hollow shaft 801 drives the cleaning brushes 805 at both ends to rotate clockwise, so that the rotation direction of the cleaning brush 805 is opposite to the transmission direction of the conveyor belt 502, thereby increasing the friction between the cleaning brush 805 and the conveyor belt 502, and improving the cleaning effect of the cleaning brush 805 on the surface of the conveyor belt 502.

The dust and impurities enter the filter box 902 through the hollow shaft 801 and the rotary joint 803, and the gas containing dust and impurities is filtered by the filter box 902 to prevent the dust and impurities from floating away.

[0022] As a further embodiment of the present invention, Figure 7-8 The two ends of the support frame 11 are fixedly connected to the support frame 10 at the bottom, and a fixed shaft 11 is provided on both sides above the support frame 10. The two fixed shafts 11 are fixedly connected between the two support frames 4. The outer shell of the fixed shaft 11 is connected to the support bearing 12. The outer walls of the two support bearings 12 are fixedly connected to the turning assembly 13. The turning assembly 13 is located between the two support frames 4. The turning assembly 13 includes two turning plates 131. The middle part of the turning plate 131 is fixed to the outer wall of the support bearing 12. The fixed shaft 11 passes through the turning plate 131 through the support bearing 12 to support and limit the turning plate 131, thereby improving the rotation stability of the turning plate 131. The two turning plates 131 are located between the two block frames 4 and are staggered with each other. A supporting groove 132 is opened on one side of the turning plate 131. The supporting groove 132 on the right turning plate 131 is in a horizontal state, and the supporting groove 132 on the left turning plate 131 is in a downwardly inclined state. Two blocking rods 133 are fixed to the front and rear sides of the turning plate 131 respectively. One end of the two turning plates 131 intersecting each other is rotatably connected to a first connecting rod 134 and a second connecting rod 135 via a pin. The first connecting rod 134 and the second connecting rod 135 are parallel to each other and the other ends are rotatably connected to the driving assembly 14 via a pin. During operation, the leftmost side of the profile is supported by the supporting groove 132 in the turning plate 131, so that the profile can be placed in the supporting groove 132. The turning plate 131 and the plurality of blocking rods 133 support the bottom of the profile, thereby improving the stability of the turning plate 131 driving the profile to rotate; When the two flipping plates 131 rotate relative to each other, the two flipping plates 131 are in a relatively overlapping state. Since the two flipping plates 131 are staggered with each other, there will be no interference in the movement trajectories of the two flipping plates 131. Since the supporting groove 132 on the left turning plate 131 is in a downwardly inclined state, a certain movable gap is given to the profile, thereby preventing the two turning plates 131 from squeezing the groove.

[0023] As a further embodiment of the present invention, Figure 9 As shown, one end of the turning assembly 13 is rotatably connected to the driving assembly 14 through a pin rod, and the driving assembly 14 is fixedly connected to one side of the bracket 10. The driving assembly 14 includes a second motor 141, and the second motor 141 is fixedly connected to the bracket 10. A driving gear 142 is fixedly connected to the output shaft of the second motor 141, and the driving gear 142 is externally meshed with a driven gear 143. A driving shaft 144 is fixed to the middle of the driven gear 143, and one end of the driving shaft 144 is rotatably connected to the rotating sleeve. Connected to the side of the retaining frame 4, the outer cover of the drive shaft 144 is connected to a bearing seat 146, and the bearing seat 146 is fixedly connected to the bracket 10. The rotation sleeve at the end of the drive shaft 144 and the support of the bearing seat 146 improve the stability of the rotation of the deflection seat 145 driven by the drive shaft 144. One end of the drive shaft 144 passes through the bearing seat 146 and is fixed with the deflection seat 145. The protruding ends on both sides of the deflection seat 145 are rotatably connected to the ends of the first connecting rod 134 and the second connecting rod 135 through pins. During operation, since the protruding ends on both sides of the deflection seat 145 are rotatably connected to the ends of the first connecting rod 134 and the second connecting rod 135 through pin rods, the protruding end on the left side of the deflection seat 145 pulls the first connecting rod 134, and the first connecting rod 134 pulls the right flipping plate 131 to rotate around the center of the fixed axis 11. During this process, the right flipping plate 131 will rotate counterclockwise and contact the upper profile. At the same time, the protruding end on the right side of the deflection seat 145 pushes the second connecting rod 135, so that the second connecting rod 135 pushes the left flipping plate 131 to rotate, so that the left flipping plate 131 can rotate clockwise, and the two flipping plates 131 can be adjusted synchronously, which is convenient for quickly flipping the profile.

[0024] Working principle of the present invention: When visually inspecting the surface of the aluminum alloy profile for oxidation defects, the aluminum alloy profile is placed on the rightmost side of the two feeding assemblies 5 so that the aluminum alloy profile contacts the conveyor belts 502 in the two feeding assemblies 5. When conveying the aluminum alloy profile, the first motor 505 is controlled to rotate in the reverse direction so that it drives the two transmission rollers 501 to rotate through the connecting shaft 504. The current transmission roller 501 drives the transmission roller 501 on the other side to rotate through the conveyor belt 502, so that the two conveyor belts 502 can work synchronously and drive the aluminum alloy profile to be conveyed to the left. In the process of conveying the aluminum alloy profile, the support wheel 5 03 supports the top of the conveyor belt 502 so that the gravity of the aluminum alloy profile acts on the support wheel 503, preventing the conveyor belt 502 from being deformed by excessive downward pressure, thereby improving the stability of the conveyor belt 502 in automatically conveying the aluminum alloy profile. When the aluminum alloy profile moves to the bottom of the optical inspection instrument 302 on the right, the first motor 505 stops working, so that the conveyor belt 502 no longer conveys the aluminum alloy profile. The display control panel 303 transmits a signal to the optical inspection instrument 302, and the optical inspection instrument 302 can detect defects on the upper surface of the aluminum alloy profile. After completing the detection work, the second motor 141 in the driving assembly 14 is controlled to work, and the second motor 141 drives the driving gear 142 to rotate in the forward direction, and the driving gear 142 drives the driving shaft 144 to rotate counterclockwise through the driven gear 143. The rotating sleeve at the end of the driving shaft 144 and the support of the bearing seat 146 improve the stability of the rotation of the deflection seat 145 driven by the driving shaft 144. Since the protruding ends on both sides of the deflection seat 145 are rotatably connected to the ends of the first connecting rod 134 and the second connecting rod 135 through the pin rod, the protruding end on the left side of the deflection seat 145 pulls the first connecting rod 134 The first connecting rod 134 pulls the right flipping plate 131 to rotate around the center of the fixed shaft 11, and the flipping plate 131 is supported and limited by the support bearing 12, thereby improving the stability of the flipping plate 131. During this process, the right flipping plate 131 will rotate counterclockwise and contact the upper profile, and the leftmost side of the profile will be supported by the supporting groove 132 in the flipping plate 131, so that the profile can be erected in the supporting groove 132, and the bottom of the profile is supported by the flipping plate 131 and multiple blocking rods 133, thereby improving the stability of the counterclockwise rotation of the profile driven by the flipping plate 131; At the same time, the protruding end on the right side of the deflection seat 145 pushes the second connecting rod 135, so that the second connecting rod 135 pushes the left flipping plate 131 to rotate, so that the left flipping plate 131 can rotate clockwise. When the deflection seat 145 rotates one circle, the two flipping plates 131 are in a relatively overlapping state. Since the two flipping plates 131 are staggered with each other, there is no interference with the movement trajectories of the two flipping plates 131. At this time, the right flipping plate 131 can flip the profile into the supporting groove 132 in the left flipping plate 131. Since the supporting groove 132 on the left flipping plate 131 is in a downward tilted state, The profile has a certain movable gap to prevent the two flipping plates 131 from squeezing the profile groove. As the deflection seat 145 continues to rotate counterclockwise for one circle, the protruding end of the deflection seat 145 pushes the right flipping plate 131 through the first connecting rod 134, and the protruding end of the other side of the deflection seat 145 pulls the left flipping plate 131, so that the right flipping plate 131 can rotate clockwise and return to its original position, and the left flipping plate 131 drives the profile to rotate counterclockwise and return to its original position, so that the profile can fall onto the two conveyor belts 502. At this time, the two flipping plates 131 return to their initial positions and are located below the profile, without interfering with the conveying movement of the profile. At this point, the profile is turned over 180 degrees. The inspected side of the profile faces downward and contacts the conveyor belt 502, while the uninspected side faces upward. Next, the optical inspection instrument 302 on the left is controlled to work and inspect the surface of the profile, thereby completing the double-sided inspection of the profile. The entire inspection process is carried out on the same conveyor line, improving inspection efficiency. Next, the first motor 505 is started to make the two conveyor belts 502 continue to drive the inspected profile to the left. The next profile to be inspected is transferred from the right side of the conveyor belt 502 to the bottom of the optical inspection instrument 302 for inspection. When the conveyor belt 502 is conveying the profile, the connecting shaft 504 will drive the two first transmission gears 7 to rotate, and the first transmission gear 7 will drive the hollow shaft 801 to rotate through the second transmission gear 802. Since the rotation directions of the first transmission gear 7 and the second transmission gear 802 are opposite, when the conveyor belt 502 is reversely transmitted, the hollow shaft 801 drives the cleaning brushes 805 at both ends to rotate clockwise, so that the rotation direction of the cleaning brushes 805 is opposite to the transmission direction of the conveyor belt 502, thereby increasing the friction between the cleaning brushes 805 and the conveyor belt 502, and improving the cleaning effect of the cleaning brushes 805 on the surface of the conveyor belt 502. At the same time, the fan 901 is started, the fan 901 works and extracts air from the filter box 902, and the filter box 902 is then Gas is extracted from the inside of the two hollow shafts 801 through the air guide pipe 903 and the rotary joint 803, so that the adsorption holes 804 at both ends of the hollow shaft 801 generate suction and adsorb the dust and small particles of impurities cleaned by the cleaning brush 805. The dust and impurities enter the filter box 902 through the hollow shaft 801 and the rotary joint 803. Since the end of the hollow shaft 801 rotates inside it through the rotary joint 803, and the hollow shaft 801 is connected to the rotary joint 803, it can be ensured that the conduction between the two is not affected during the rotation of the hollow shaft 801. Secondly, the gas containing dust and impurities is filtered through the filter box 902, and the filtered gas is discharged from the air outlet of the fan 901, thereby achieving the purpose of automatic cleaning of the conveyor belt 502.
