[0012] Preferably, the testing platform is equipped with a workpiece unloading assembly; The workpiece unloading assembly includes a first nozzle assembly and a second nozzle assembly set on the inspection table, and a collection box one and a collection box two corresponding to the positions of the first nozzle assembly and the second nozzle assembly, respectively.

Multiple structures can be adjusted according to the size of the workpiece to fit its dimensions. With the coordinated operation of these multiple structures, multiple workpieces are sequentially moved onto the turntable in a flat arrangement for inspection. This avoids the problem of workpieces being disorderly piled or overlapping during inspection, which would prevent the inspection component from clearly capturing the complete appearance of the obscured workpiece and thus avoid missed inspections.

[0017] 2. The optical image inspection device with feeding function described in this invention utilizes a material-shifting component to ensure that all workpieces arriving at conveyor belt two maintain a uniform posture with the nuts facing downwards, eliminating situations where inspection cannot be performed according to preset conditions due to inconsistent workpiece orientation, thus affecting inspection accuracy. Simultaneously, the shifting plate, during rotation, pushes overlapping workpieces down before they reach the lifting plate, effectively preventing interference with subsequent material discharge cycles caused by workpieces getting stuck below the lifting plate.

The feeding cover 3 is rotatably connected to one side of the fixed base 4.

One side of the two width-adjusting rods 21 extends into the inner cavity of the feeding cover 3. A first conveyor belt 26 is provided on the width-adjusting rods 21. After the workpiece is lifted to a certain height by the lifting plates 29, the workpiece falls on the two width-adjusting rods 21 and contacts the first conveyor belt 26. The first conveyor belt 26 drives the workpiece to move towards the second conveyor belt 28.

[0023] In this embodiment, as Figures 2-8 As shown, a gear 7 is rotatably connected to one side of the fixed base 4, and a gear ring 31 is fixedly sleeved on the outer wall of the feeding cover 3. The gear 7 and the gear ring 31 mesh with each other.

[0024] A motor 6 is fixedly connected to one side of the feeding hood 3, and the output end of the motor 6 is fixedly connected to the gear 7.

[0025] Two cylinders 20 are symmetrically and fixedly connected on the frame 19, and the piston ends of the two cylinders 20 are respectively fixedly connected to one end of the two width adjustment rods 21.

[0026] A guide plate 18 is fixedly connected to one side of the upper end of the frame 19, and the lower edge of the guide plate 18 is in contact with the upper surface of the conveyor belt 28.

[0027] A return plate 8 is fixedly connected to one side of the upper end face of the testing table 2. The upper surface of the return plate 8 is inclined, and one side of the return plate 8 is in contact with one side edge of the feeding cover 3.

[0028] The inspection table 2 is equipped with a workpiece unloading assembly; The workpiece unloading assembly includes a first nozzle assembly 13 and a second nozzle assembly 14 disposed on the inspection table 2, and a collection box 15 and a collection box 2 16 respectively corresponding to the positions of the first nozzle assembly 13 and the second nozzle assembly 14.

[0029] A tilted lower slide plate 30 is fixedly connected to one end face of the fixed base 4, and the end of the lower slide plate 30 away from the fixed base 4 is aligned with two width adjustment rods 21.

[0030] A guide rod 24 is slidably connected to one end of the frame 19 near the feeding hood 3. A lifting plate 22 is fixedly connected to the upper end of the guide rod 24. A cylinder 27 is fixedly connected to one side of the frame 19. The piston end of the cylinder 27 is fixedly connected to one side of the bottom of the lifting plate 22.

[0031] Specifically, in existing technologies, hexagonal round head flange nuts, as commonly used fasteners in industrial production, often require inspection using optical imaging technology during manufacturing to remove defective products. Furthermore, to achieve continuous batch inspection, a conveyor belt is used to transport the hexagonal round head flange nuts to be inspected onto a transparent glass turntable. As the turntable rotates, the nuts pass through multiple sets of inspection components for testing. However, the nuts tend to pile up or overlap randomly on the turntable, making it difficult for the inspection components to clearly capture the complete appearance of the obscured workpieces, leading to missed inspections.

[0032] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: This method is only applicable to the inspection of hexagonal round head flange nuts of the same specification within the same batch. The hexagonal round head flange nuts are characterized by their flat shape, with a flange at one end and a flange diameter larger than the nut diameter. For ease of description later, the hexagonal round head flange nut will be referred to as the workpiece.

[0033] First, based on the diameters of the workpiece nut and flange, two cylinders 20 simultaneously drive two width-adjusting rods 21 to move in opposite directions or away from each other, adjusting the distance between the two width-adjusting rods 21 so that the distance is less than the flange diameter but greater than the maximum diameter of the nut. Then, cylinder 27 drives the lifting plate 22 to rise and fall, adjusting the distance between the lower edge of the lifting plate 22 and the upper surface of the two width-adjusting rods 21, ensuring that this distance is equal to the workpiece thickness.

[0034] After completing the above adjustment operations, place the multiple workpieces to be inspected into the bottom of the inner cavity of the loading cover 3. Then, use motor 6 to drive gear 7 to rotate, which will cause the loading cover 3 to rotate under the action of gear 7 and gear ring 31. When the loading cover 3 rotates, the lifting plate 29 on its inner wall will lift the workpiece located at the bottom of the inner cavity of the loading cover 3. When the workpiece rises to a certain height, it will fall down onto the lower slide plate 30 along the lifting plate 29, and then onto the two width adjustment rods 21 along the lower slide plate 30. Since the workpiece is flat, it is difficult for the workpiece to stand upright on the width adjustment rods 21. Therefore, the workpiece that reaches the two width adjustment rods 21 in an upright state will fall down along the edge of the width adjustment rods 21 and fall back into the loading cover 3 along the return plate 8.

[0035] Therefore, the workpiece can only be stably placed on the width adjustment rod 21 when the nut face or flange face of the workpiece is in contact with the width adjustment rod 21. Furthermore, when the nut end of the workpiece passes through the gap between the two width adjustment rods 21, the workpiece is centered between the two rods 21. Additionally, the flange edge of the workpiece will be in contact with the first conveyor belt 26, and the workpiece will move towards the second conveyor belt 28 under the operation of the first conveyor belt 26.

[0036] Since the distance between the lower edge of the lifting plate 22 and the upper surface of the width adjustment rod 21 is equal to the workpiece thickness, only one flat workpiece can pass under the lifting plate 22 at a time. When the workpiece reaches the end of the width adjustment rod 21, the workpiece is removed from the first conveyor belt 26 and placed on the second conveyor belt 28. At this time, the workpiece will contact the guide plate 18 under the operation of the second conveyor belt 28 and move along the guide plate 18 in an arranged state to the upper surface of the turntable 5. At this time, the second motor 17 drives the turntable 5 to rotate, and multiple workpieces make circular motion and pass through the first detection camera 10, the second detection camera 12 and the ring light source 9 distributed along the circumference of the turntable 5 in sequence. The workpiece can be detected under the cooperation of the three.

[0037] If the workpiece is qualified, when the workpiece reaches the first nozzle assembly 13, the first nozzle assembly 13 blows the workpiece into the first collection box 15; if the workpiece is unqualified, when the workpiece reaches the second nozzle assembly 14, the second nozzle assembly 14 blows the workpiece into the second collection box 16, thereby realizing the automatic detection and classification of workpieces.

[0038] Repeating the above operation, under the continuous rotation of the loading cover 3, multiple workpieces are continuously lifted until they can be stably placed on the width adjustment rod 21. With the coordinated cooperation of the width adjustment rod 21, the lifting plate 22, the first conveyor belt 26, and the second conveyor belt 28, multiple workpieces are moved sequentially to the turntable 5 in a flat arrangement for inspection. This avoids the phenomenon of missed inspections caused by the workpieces being piled up or overlapping in a disordered manner during inspection, which makes it difficult for the inspection components to clearly obtain the complete appearance of the covered workpieces.

[0039] In this embodiment, as Figure 6 and Figure 8 As shown, the lifting plate 22 is equipped with a material feeding assembly; The feeding assembly includes a feed plate 25 rotatably connected to one end face of the lifting plate 22, and a motor 23 is fixedly connected to one side of the lifting plate 22. The output end of the motor 23 is fixedly connected to one end of the feed plate 25.

[0040] Specifically, in the above embodiments, although the aforementioned structure enables the workpieces to be arranged flat, the orientation of the workpieces is still random. Since the lighting angle of the ring light source 9 and the detection steps need to be set for a specific orientation, this uncertainty in orientation makes it difficult to perform the detection according to preset conditions, affecting the accuracy of the detection results to some extent. Furthermore, when workpieces are stacked on the width adjustment rod 21, although they can still move with the width adjustment rod 21, they are prone to jamming when passing under the lifting plate 22, thus interfering with the subsequent material discharge cycle.

[0041] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: The lever 25 can reciprocate under the drive of motor 23, and the lowest position of its lower edge when rotating can be adjusted by controlling the height of the lifting plate 22. The distance between this lowest point and the upper surface of conveyor belt 26 is equal to the thickness of the workpiece flange. Therefore, during the movement of the flat workpiece along conveyor belt 26, it will only avoid contact with the swinging lever 25 when the nut passes through the gap between the two width-adjusting rods 21. Workpieces in other positions will be pushed onto the return plate 8 by the lever 25. This ensures that all workpieces arriving at conveyor belt 28 maintain a uniform nut-facing orientation, preventing situations where inconsistent workpiece orientation causes the inspection to fail to meet preset conditions and thus affecting inspection accuracy. Simultaneously, the lever 25 pushes overlapping workpieces down before they reach the lifting plate 22 during rotation, effectively preventing interference with subsequent discharge cycles caused by workpieces getting stuck below the lifting plate 22.

[0042] Working principle: First, based on the diameters of the workpiece nut and flange, two cylinders 20 simultaneously drive two width-adjusting rods 21 to move in opposite directions or away from each other, adjusting the distance between the two width-adjusting rods 21 so that the distance is less than the flange diameter but greater than the maximum diameter of the nut. Then, cylinder 27 drives the lifting plate 22 to rise and fall, adjusting the distance between the lower edge of the lifting plate 22 and the upper surface of the two width-adjusting rods 21, ensuring that this distance is equal to the workpiece thickness.

[0043] After completing the above adjustment operations, place the multiple workpieces to be inspected into the bottom of the inner cavity of the loading cover 3. Then, use motor 6 to drive gear 7 to rotate, which will cause the loading cover 3 to rotate under the action of gear 7 and gear ring 31. When the loading cover 3 rotates, the lifting plate 29 on its inner wall will lift the workpiece located at the bottom of the inner cavity of the loading cover 3. When the workpiece rises to a certain height, it will fall down onto the lower slide plate 30 along the lifting plate 29, and then onto the two width adjustment rods 21 along the lower slide plate 30. Since the workpiece is flat, it is difficult for the workpiece to stand upright on the width adjustment rods 21. Therefore, the workpiece that reaches the two width adjustment rods 21 in an upright state will fall down along the edge of the width adjustment rods 21 and fall back into the loading cover 3 along the return plate 8.

[0044] Therefore, the workpiece can only be stably placed on the width adjustment rod 21 when the nut face or flange face of the workpiece is in contact with the width adjustment rod 21. Furthermore, when the nut end of the workpiece passes through the gap between the two width adjustment rods 21, the workpiece is centered between the two rods 21. Additionally, the flange edge of the workpiece will be in contact with the first conveyor belt 26, and the workpiece will move towards the second conveyor belt 28 under the operation of the first conveyor belt 26.

[0045] Since the distance between the lower edge of the lifting plate 22 and the upper surface of the width adjustment rod 21 is equal to the workpiece thickness, only one flat workpiece can pass under the lifting plate 22 at a time. When the workpiece reaches the end of the width adjustment rod 21, the workpiece is removed from the first conveyor belt 26 and placed on the second conveyor belt 28. At this time, the workpiece will contact the guide plate 18 under the operation of the second conveyor belt 28 and move along the guide plate 18 in an arranged state to the upper surface of the turntable 5. At this time, the second motor 17 drives the turntable 5 to rotate, and multiple workpieces make circular motion and pass through the first detection camera 10, the second detection camera 12 and the ring light source 9 distributed along the circumference of the turntable 5 in sequence. The workpiece can be detected under the cooperation of the three.

[0046] If the workpiece is qualified, when the workpiece reaches the first nozzle assembly 13, the first nozzle assembly 13 blows the workpiece into the first collection box 15; if the workpiece is unqualified, when the workpiece reaches the second nozzle assembly 14, the second nozzle assembly 14 blows the workpiece into the second collection box 16, thereby realizing the automatic detection and classification of workpieces.

[0047] Repeat the above operation. With the continuous rotation of the loading cover 3, multiple workpieces are continuously lifted until they can be stably placed on the width adjustment rod 21. With the coordinated cooperation of the width adjustment rod 21, the lifting plate 22, the first conveyor belt 26, and the second conveyor belt 28, multiple workpieces are moved in a flat arrangement to the turntable 5 for inspection.

[0048] The lever 25 can reciprocate under the drive of motor 23, and the lowest position of its lower edge when rotating can be adjusted by controlling the height of the lifting plate 22. The distance between this lowest point and the upper surface of conveyor belt 26 is equal to the thickness of the workpiece flange. Therefore, as the flat workpiece moves with conveyor belt 26, it will only avoid contact with the swinging lever 25 when the nut passes through the gap between the two width-adjusting rods 21. Workpieces in other positions will be pushed onto the return plate 8 by the lever 25. This ensures that all workpieces arriving at conveyor belt 28 maintain a uniform nut-facing posture.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
