[0002] New materials refer to structural materials with excellent performance and functional materials with special properties that have been recently developed or are under development.

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] like Figures 1 to 6As shown in the embodiment of the present invention, an optical inspection device for surface defects includes an inspection base 1. Uprights 2 are provided on both the front and back of the inspection base 1, and a crossbar 3 is fixedly installed between the two uprights 2. A scanner 4 is fixedly installed at the bottom of the crossbar 3. A translation component is provided on the inner wall of the inspection base 1, and a pressing component is provided on the outer wall of the translation component. A driving component is provided on the outer side of the inspection base 1, and a loading component and a unloading component are respectively provided on both sides of the inspection base 1. After the device is started, the driving component drives the inspection base 1 to rotate at a uniform speed. During the rotation of the inspection base 1, the loading component automatically moves the shaft-like new material parts to be inspected to the top of the inspection base 1. Then, under the action of the pressing component, the translation component is translated. When the translation component is translated, the inspection base 1 is in an inclined state. At this time, the shaft-like new material parts located on the inspection base will move along with the translation component. During operation, because the rolling friction is less than the sliding friction, the shaft-type new material parts will roll at a constant speed. When the translation component moves, the upright 2 will be driven by the pressing component to move the scanner 4 along the shaft-type new material parts through the crossbar 3, thereby detecting the surface defects of the shaft-type new material parts. After the shaft-type new material parts have been inspected, as the inspection seat 1 rotates, the inspection seat 1 will cooperate with the unloading component to unload the shaft-type new material parts. After unloading, the inspection seat 1 will be loaded again by the loading component, thereby realizing repeated inspection. In summary, this device realizes automatic loading, automatic inspection and automatic unloading, reduces inspection downtime, and can perform cyclic inspection of shaft-type new material parts. The cyclic operation mode allows the equipment to run continuously, and can process more parts per unit time, reducing the time consumed by repeatedly fixing the shaft-type new material parts with the fixing fixture, effectively improving the inspection efficiency of the device.

[0034] like Figures 1 to 5 As shown, the translation component includes a guide plate 5, which is slidably mounted on the inner wall of the detection seat 1. Several slide rods 6 are fixedly mounted on the inner wall of the detection seat 1, and the outer walls of the slide rods 6 are slidably connected to the inner wall of the guide plate 5. Several reset elastic elements 7 are fixedly mounted between the inner wall of the detection seat 1 and the outer wall of the guide plate 5, and the several reset elastic elements 7 are respectively sleeved on the outer side of the slide rods 6. The detection seat 1 is rotated at a constant speed by the drive component, and the feeding component moves the part to the horizontal section of the detection seat 1. Due to the rotation of the detection seat 1, the horizontal section of the detection seat 1 will tilt, so the part located on the detection seat 1 will keep in contact with the guide plate 5 under the action of gravity. As the detection seat 1 rotates, the squeezing component will move the guide plate 5 along the slide rods 6. In order to keep in contact with the guide plate 5, the part will follow the guide plate 5. Since the rolling friction is less than the sliding friction, the part will roll at a constant speed when it moves, so that the outer circumferential surface of the part can be fully inspected.

[0035] like Figures 4 to 5As shown, the extrusion assembly includes two translation plates 8, which are symmetrically and fixedly installed on the outer wall of the guide plate 5. The outer wall of the translation plates 8 is slidably connected to the inner wall of the detection seat 1. Two uprights 2 are respectively fixedly installed on the outer wall of the translation plates 8. Force rollers 9 are rotatably installed at the ends of the two translation plates 8 that are far apart from each other. Extrusion rings 10 are provided on both the front and back of the detection seat 1. The two force rollers 9 are located inside the two extrusion rings 10. When the detection plate 1 rotates, the force rollers 9 will rotate accordingly. Since the force rollers 9 are located inside the extrusion rings 10, they will contact the extrusion rings 10 and be squeezed by them when they rotate. The inner side of the extrusion rings 10 is teardrop-shaped, so the force... When roller 9 rotates one revolution, its straight-line distance from the axis of the detection seat 1 first decreases, then remains constant, and finally increases and resets. When the force roller 9 moves under the action of the extrusion ring 10, it will drive the guide plate 5 to move through the translation plate 8. After the feeding is completed, the force roller 9 will be squeezed by the extrusion ring 10, and the distance between the force roller 9 and the axis of the detection seat 1 will decrease, so that the guide plate 5 slides along the slide bar 6, achieving the effect of guiding the parts to roll. When the translation plate 8 moves, it will drive the upright 2 to move. When the upright 2 moves, it will drive the scanner 4 to move through the crossbar 3. The relative position of the scanner 4 and the parts remains unchanged, thereby inspecting the surface of the parts.

[0036] like Figures 1 to 3 As shown, the drive assembly includes two support frames 11, symmetrically arranged on opposite sides of the two extrusion rings 10. The two extrusion rings 10 are fixedly mounted on the outer wall of the support frame 11, and a rotating shaft 12 is rotatably mounted between the two support frames 11. The detection seat 1 is fixedly mounted on the outer wall of the rotating shaft 12. A drive motor 13 is fixedly mounted on the outer wall of one of the support frames 11, and the output end of the drive motor 13 is fixedly connected to one end of the rotating shaft 12. The support frame 11 supports the detection seat 1 through the rotating shaft 12, keeping the detection seat 1 in a suitable position. When the drive motor 13 is started, the drive motor 13 drives the rotating shaft 12 to rotate, which in turn drives the detection seat 1 to rotate, thereby providing power for the operation of the device.

[0037] like Figures 3 to 4 and Figure 6As shown, the feeding assembly includes a guide plate 14, which is fixedly installed on one side of the detection seat 1. A hook plate 15 is fixedly installed on the outer wall of the guide plate 14. A support seat A16 is provided on the side of the detection seat 1 near the hook plate 15. A picking seat 17 is fixedly installed on the top of the support seat A16. A picking port 18 is opened at the bottom of the picking seat 17. The part to be tested is placed inside the picking seat 17. Since the picking seat 17 is tilted, the part will slide towards the side near the hook plate 15 under its own weight. When the detection seat 1 rotates, the detection seat 1 will drive the hook plate 15 to rotate through the guide plate 14. When the hook plate 15 rotates, it will pass through the picking port 18 and lift the lowest part. At the same time, the rotation of the detection seat 1 will cause the guide plate 14 and the hook plate 15 to tilt. The part will slide off the hook plate 15 and move to the detection seat 1 through the guide plate 14, thereby achieving the effect of automatic feeding.

[0038] like Figure 1 As shown, the feeding assembly includes a support base B19, which is located on the side of the detection seat 1 away from the support base A16. A feeding plate 20 is fixedly installed on the top of the support base B19. A notch is opened on the side of the feeding plate 20 near the detection seat 1. A sliding seat 21 is fixedly installed on the vertical section of the detection seat 1. After the device completes the detection work, as the detection seat 1 rotates, the part will slide from the guide plate 5 to the side of the detection seat 1 where the sliding seat 21 is installed. Then the part will continue to slide down the detection seat 1 onto the feeding plate 20. Finally, the feeding is completed by the inclined feeding plate 20, realizing the effect of automatic feeding. When the force roller 9 moves to the minimum straight distance from the axis of the detection seat 1, the side of the guide plate 5 near the part will be aligned with the sliding seat 21. Therefore, when the part slides down from the guide plate 5, it will slide down along the sliding seat 21 to the other side of the detection seat 1, preventing the part from falling directly from the guide plate 5 and causing damage, thus protecting the part.

[0039] like Figures 7 to 9As shown, an adjusting shaft 22 is rotatably mounted on the inner wall of the extrusion ring 10, and an extrusion block 23 is rotatably mounted on the outer wall of the adjusting shaft 22. The outer wall of the extrusion block 23 is slidably connected to the inner wall of the extrusion ring 10. An adjusting component is provided on the top of the extrusion ring 10, and a separating component is provided inside the sliding material seat 21. During the detection process, when a defect is detected on the surface of a part, the control system will cause the adjusting component to push the extrusion block 23. The extrusion block 23 will rotate around the adjusting shaft 22 toward the inner side of the extrusion ring 10. Since the extrusion block 23 rotates to the inner side of the extrusion ring 10, the force roller 9 will be squeezed by the extrusion block 23 when it rotates inside the extrusion ring 10. Under the action of the extrusion block 23, the minimum straight-line distance between the force roller 9 and the axis of the detection seat 1 is reduced, thereby changing the final position of the guide plate 5 that drives the part to move. Then, the separation component can automatically pick out the defective parts, achieving the effect of automatic transfer of defective products and increasing the convenience of the device.

[0040] like Figures 7 to 8 As shown, the adjustment assembly includes a mounting plate 24, which is fixedly mounted on the top of the extrusion ring 10. Hinges 25 are fixedly mounted on the horizontal section of the mounting plate 24 and the outer wall of the extrusion block 23. An automatic telescopic rod 26 is fixedly mounted between the two hinges 25. When a defective product is detected, the control system will extend the automatic telescopic rod 26. After the automatic telescopic rod 26 extends, it will push the extrusion block 23 to rotate around the adjustment shaft 22 to the inner side of the extrusion ring 10, thereby achieving the effect of automatically adjusting the position of the extrusion block 23.

[0041] like Figure 9 As shown, the separation assembly includes a guide groove 27 at the bottom of the slide base 21. A torsion spring shaft 28 is fixedly installed on the inner wall of the slide base 21, and a baffle 29 is fixedly installed on the outer wall of the torsion spring shaft 28. The baffle 29 engages with the slide base 21 via the torsion spring shaft 28. A defective product collection box 31 is provided on the side of the support base B19 near the detection seat 1. When the quality of the part is detected to be fine, the force roller 9 moves to the minimum straight-line distance from the axis of the detection seat 1, which will align the side of the guide plate 5 near the part with the slide base 21 to achieve automatic feeding. When the quality of the part is detected to be fine, the force roller 9 moves to the minimum straight-line distance from the axis of the detection seat 1, which will align the side of the guide plate 5 near the part with the slide base 21 to achieve automatic feeding. When a defect is detected, the control system rotates the extrusion block 23, thereby reducing the minimum straight-line distance between the force roller 9 and the axis of the detection seat 1. As a result, the side of the guide plate 5 closest to the part moves to align with the material inlet of the guide trough 27. As the detection seat 1 rotates, the defective part enters the interior of the guide trough 27. When the baffle 29 rotates downward, the part will push the baffle 29 open under its own weight and fall out of the interior of the guide trough 27. The fallen part will enter the interior of the defective product collection box 31 for separate collection, thereby achieving the effect of defective product transfer.

[0042] like Figure 1As shown, a base 30 is provided below the detection seat 1. The support frame 11, support seat A16 and support seat B19 are all fixedly installed on the top of the base 30. The defective product collection box 31 is slidably installed on the top of the base 30. The base 30 supports the entire device to ensure the overall stability of the device. The defective product collection box 31 can slide off the base 30, which facilitates the transfer of defective products.

[0043] Working Principle: After the device is started, the drive assembly drives the detection seat 1 to rotate at a constant speed. During the rotation of the detection seat 1, the feeding assembly automatically moves the shaft-type new material parts to be detected above the detection seat 1. Then, under the action of the pressing assembly, the translation assembly is moved. When the translation assembly is moving, the detection seat 1 will be in an inclined state. At this time, the shaft-type new material parts located on the detection seat will move with the translation assembly. When the shaft-type new material parts move, because their rolling friction is less than their sliding friction, the shaft-type new material parts will roll at a constant speed. When the translation assembly is moving, the upright 2 will be driven by the pressing assembly to drive the scanner 4 to follow through the crossbar 3. The new material shaft parts move to detect surface defects. After the new material shaft parts are detected, the detection seat 1 rotates and, together with the unloading assembly, unloads the new material shaft parts. After unloading, the detection seat 1 is reloaded by the loading assembly, thus achieving repeated detection. In summary, this device realizes automatic loading, automatic detection, and automatic unloading, reducing detection downtime. It can perform cyclic detection of new material shaft parts. The cyclic operation mode allows the equipment to run continuously, processing more parts per unit time and reducing the time consumed by repeatedly fixing the new material shaft parts with fixtures, effectively improving the detection efficiency of the device.

[0044] The drive assembly rotates the detection seat 1 at a constant speed, and the feeding assembly moves the part to the horizontal section of the detection seat 1. Due to the rotation, the horizontal section of the detection seat 1 tilts, causing the part on the detection seat 1 to remain in contact with the guide plate 5 under gravity. As the detection seat 1 rotates, the extrusion assembly moves the guide plate 5 along the slide bar 6. To maintain contact with the guide plate 5, the part moves along with it. Since rolling friction is less than sliding friction, the part rolls at a constant speed, allowing for comprehensive inspection of the outer circumference of the part. When the detection plate 1 rotates, the force roller 9 rotates accordingly. Because the force roller 9 is located inside the extrusion ring 10, it contacts and is extruded by the extrusion ring 10 during rotation. The inner side of the extrusion ring 10 is teardrop-shaped, so when the force roller 9 rotates one revolution, its linear distance from the axis of the detection seat 1 changes. The force roller 9 moves under the action of the extrusion ring 10, and then moves the guide plate 5 through the translation plate 8. After the feeding is completed, the force roller 9 will be squeezed by the extrusion ring 10, and the distance between the force roller 9 and the axis of the detection seat 1 will decrease, so that the guide plate 5 slides along the slide bar 6, achieving the effect of guiding the parts to roll. When the translation plate 8 moves, it will drive the upright 2 to move. When the upright 2 moves, it will drive the scanner 4 to move through the crossbar 3. The relative position of the scanner 4 and the parts remains unchanged, so as to inspect the surface of the parts. The support frame 11 supports the detection seat 1 through the rotating shaft 12, so that the detection seat 1 is kept in a suitable position. The drive motor 13 is started, and the drive motor 13 will drive the rotating shaft 12 to rotate. When the rotating shaft 12 rotates, it will drive the detection seat 1 to rotate, thus providing power for the operation of the device.

[0045] The parts to be inspected are placed inside the pick-up seat 17. Since the pick-up seat 17 is tilted, the parts will slide towards the hook plate 15 under their own weight. When the inspection seat 1 rotates, it drives the hook plate 15 to rotate via the guide plate 14. As the hook plate 15 rotates, it passes through the pick-up port 18 and lifts the lowest part. Simultaneously, the rotation of the inspection seat 1 causes the guide plate 14 and hook plate 15 to tilt, causing the parts to slide off the hook plate 15 and move onto the inspection seat 1 via the guide plate 14, thus achieving automatic feeding. After the device completes the inspection, As the detection seat 1 rotates, the part slides off the guide plate 5 onto the side of the detection seat 1 where the sliding seat 21 is installed. Then, the part continues to slide down the detection seat 1 onto the unloading plate 20. Finally, the part is unloaded by the inclined unloading plate 20, achieving the effect of automatic unloading. When the force roller 9 moves to the minimum straight-line distance from the axis of the detection seat 1, the side of the guide plate 5 closest to the part will align with the sliding seat 21. Therefore, when the part slides off the guide plate 5, it will slide down along the sliding seat 21 to the other side of the detection seat 1, preventing the part from falling directly off the guide plate 5 and causing damage, thus protecting the part.

[0046] During the inspection process, when a defect is detected on the surface of a part, the control system will cause the adjusting component to push the extrusion block 23. The extrusion block 23 will rotate around the adjusting shaft 22 towards the inside of the extrusion ring 10. As the extrusion block 23 rotates to the inside of the extrusion ring 10, the force roller 9 will be squeezed by the extrusion block 23 when it rotates inside the extrusion ring 10. Under the action of the extrusion block 23, the minimum straight-line distance between the force roller 9 and the axis of the detection seat 1 will decrease, thereby changing the final position of the guide plate 5 that drives the part to move. Then, the separation component can automatically pick out the defective parts, achieving the effect of automatic transfer of defective products and increasing the convenience of the device. When a defective product is detected, the control system will extend the automatic telescopic rod 26. After the automatic telescopic rod 26 extends, it will push the extrusion block 23 to rotate around the adjusting shaft 22 towards the extrusion ring 10. The inner side of the device achieves the effect of automatically adjusting the position of the extrusion block 23. When the quality of the part is detected to be fine, the force roller 9 moves to the minimum straight distance from the axis of the detection seat 1, which will align the side of the guide plate 5 near the part with the sliding seat 21 to achieve automatic feeding. When the quality of the part is detected to be defective, the control system makes the extrusion block 23 rotate, which reduces the minimum straight distance between the force roller 9 and the axis of the detection seat 1. Therefore, the side of the guide plate 5 near the part will move to align with the material inlet of the guide groove 27. As the detection seat 1 rotates, the defective part will enter the interior of the guide groove 27. When the baffle 29 rotates to face downward, the part will push the baffle 29 open under its own gravity and fall out of the interior of the guide groove 27. The fallen part will enter the interior of the defective product collection box 31 for separate collection, thereby achieving the effect of defective product transfer.
