Description

Technical Field

[0001] This invention relates to the field of connector appearance inspection technology, and in particular to a connector appearance inspection device and its inspection process. Background Technology

[0002] The essence of the Industrial Internet is to comprehensively connect people, machines, things, and systems through new-generation information technologies (such as 5G, IoT, cloud computing, big data, artificial intelligence, and digital twins) to build a brand-new manufacturing and service system covering the entire industrial chain and value chain, in order to achieve the goals of data-driven, intelligent decision-making, resource optimization, and efficiency improvement. To achieve this goal, the first step is to acquire data, including equipment status data, environmental data, energy consumption data, and most importantly, product quality data. Using inspection cameras is the most core and efficient technical means to acquire product appearance quality data.

[0003] A search of existing technologies revealed that Chinese Patent CN220104895U discloses an inspection device for the appearance of automotive electronic connectors. The device includes a flipping mechanism that flips the automotive connector and moves it onto a second belt conveyor, and a second CCD camera that performs a second inspection of the appearance of the automotive connector. This device can perform the flipping operation on automotive electronic connectors.

[0004] However, it is worth considering that although the connector can be flipped, the side of the connector cannot be inspected, resulting in a blind spot. This leads to insufficient detection rate of process defects with three-dimensional features, affecting the confidence and reliability of the overall inspection system. Furthermore, it requires waiting for the flipping mechanism to reset from above the second belt conveyor to above the first belt conveyor, and the flipping mechanism needs to move back and forth once before the next flipping can begin. The time interval between two flips is relatively long, affecting the inspection efficiency and presenting certain limitations.

[0005] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a connector appearance inspection device and its inspection process to solve the problems of blind spots and long time intervals between two flipping.

[0020] The present invention also provides a connector appearance inspection process, applied to the connector appearance inspection device described above, comprising the following steps:

[0021] Step 1: The connector to be inspected is transported to the area below the first inspection camera by the first belt conveyor. The top surface of the connector is inspected by the first inspection camera. The connector is simultaneously located between two third inspection cameras. The two adjacent third inspection cameras inspect both sides of the connector. The first belt conveyor drives the connector to move toward the fifth inspection camera.

[0022] Step 2: The connector facing the fifth detection camera is detected by the fifth detection camera. When the connector moves to the preset position, the fifth detection camera is driven by the avoidance component to avoid the moving connector. The first belt conveyor transports the connector to the storage piece. The avoidance component drives the fifth detection camera to reset to the initial position.

[0023] Step 3: By adjusting the structure, the storage component is moved to the top of the third belt conveyor. The last side of the connector is inspected by the fourth detection camera located above the third belt conveyor. At the same time, the next empty storage component is moved to the side of the first belt conveyor. The next connector can be stored in the storage component. When there are defects on the top and four sides of the connector, the connector on the storage component is slid onto the third belt conveyor by adjusting the structure. When there are no defects on the top and four sides of the connector, the connector on the storage component is moved to the top of the second belt conveyor by adjusting the structure.

[0024] Step 4: Adjust the structure to drive the storage component to rotate 180 degrees so that the side of the connector that was originally located below faces upward. By adjusting the structure to drive the storage component, the connector slides onto the second belt conveyor. The second belt conveyor drives the connector to move below the second detection camera, so that the side of the connector that was originally located below can be detected by the second detection camera.

[0025] The beneficial effects of this invention are as follows: A first belt conveyor transports the connector to be inspected to a position below a first inspection camera. The first inspection camera inspects the top surface of the connector. Simultaneously, the connector is positioned between two third inspection cameras, which inspect both sides of the connector. The first belt conveyor drives the connector towards a fifth inspection camera, which inspects the side of the connector facing it. When the connector reaches a preset position, a clearance component drives the fifth inspection camera to avoid the moving connector. The first belt conveyor then transports the connector onto a receiving component. The clearance component drives the fifth inspection camera to reset to its initial position. An adjustment structure drives the receiving component to move above a third belt conveyor. A fourth inspection camera located above the third belt conveyor inspects the last side of the connector. Simultaneously, the adjustment structure drives the next empty receiving component to move synchronously to one side of the first belt conveyor. The connector can then be collected using the receiving component. The system takes in a connector. When defects are found on the top and four sides of the connector, the connector is slid onto the third belt conveyor by adjusting the structure. When the top and four sides of the connector are free of defects, the connector is moved to the top of the second belt conveyor by adjusting the structure. The structure then rotates the connector 180 degrees so that the side of the connector that was originally facing down faces up. The connector is then slid onto the second belt conveyor, which moves it to the bottom of the second inspection camera. The second inspection camera can then inspect the side of the connector that was originally facing down. This allows for inspection of all six sides of the connector, avoiding blind spots and improving the confidence and reliability of the overall inspection system. Furthermore, using multiple receivers reduces the time interval between flipping adjacent connectors, improving inspection efficiency and preventing defective parts from moving back to the bottom of the second inspection camera, thus avoiding wasting time on known defective products.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0041] Example 1, by Figure 1 , Figure 2 , Figure 3 and Figure 6 The present invention includes a testing platform 1 and a first belt conveyor 2, a second belt conveyor 3, and a third belt conveyor 4 respectively fixedly installed on the testing platform 1, and further includes:

[0042] The top surface inspection unit includes a first inspection camera 5 and a second inspection camera 6 fixedly installed on the inspection table 1. The first inspection camera 5 is located above the first belt conveyor 2, and the second inspection camera 6 is located above the second belt conveyor 3.

[0043] The position adjustment assembly includes at least three storage components for housing the connector to be tested and an adjustment structure for driving the storage components to move to a preset position and flip over;

[0044] The side inspection unit includes two third inspection cameras 36 positioned above the first belt conveyor 2 and one fourth inspection camera 37 positioned above the third belt conveyor 4. Both the third and fourth inspection cameras 36 and 37 are fixedly connected to the inspection platform 1. A fifth inspection camera 38 is positioned above the first belt conveyor 2. The inspection platform 1 is equipped with a clearance component for driving the fifth inspection camera 38 to avoid the connector to be inspected. The connector to be inspected is conveyed to the area below the first inspection camera 5 via the first belt conveyor 2. The top surface of the connector is inspected by the first inspection camera 5. The connector is simultaneously located between the two third inspection cameras 36 and 4. Between the three detection cameras 36, two adjacent third detection cameras 36 detect both sides of the connector, and the first belt conveyor 2 drives the connector to move toward the fifth detection camera 38. The fifth detection camera 38 detects the side of the connector facing the fifth detection camera 38. When the connector moves to a preset position, the fifth detection camera 38 is driven by an obstacle avoidance component to avoid the moving connector. The first belt conveyor 2 transports the connector to the storage component. The obstacle avoidance component drives the fifth detection camera 38 to reset to its initial position, and the storage component is driven to move above the third belt conveyor 4 by an adjustment structure. The fourth inspection camera 37 above the three belt conveyors 4 inspects the last side of the connector. Simultaneously, the adjustment mechanism drives the next empty receiving unit to move to one side of the first belt conveyor 2. The receiving unit then stores the next connector. If defects are found on the top and four sides of the connector, the adjustment mechanism drives the connector on the receiving unit to slide onto the third belt conveyor 4. If no defects are found on the top and four sides of the connector, the adjustment mechanism drives the connector on the receiving unit to move above the second belt conveyor 3. The adjustment mechanism also drives the receiving unit to rotate 180 degrees so that the connector, originally located below... With one side facing upwards, the connector on the storage component is slid onto the second belt conveyor 3 by adjusting the structure. The second belt conveyor 3 then drives the connector to move below the second inspection camera 6. The second inspection camera 6 can then inspect the side of the connector that was originally located below, allowing for the inspection of all six sides of the connector. This avoids blind spots and improves the confidence and reliability of the overall inspection system. Furthermore, the use of multiple storage components reduces the time interval between flipping adjacent connectors, improving inspection efficiency. It also prevents defective parts from moving back below the second inspection camera 6, thus avoiding wasting a lot of time on known defective products.

[0045] Example 2, based on Example 1, is... Figure 1 , Figure 2 , Figure 4 , Figure 7 , Figure 8 , Figure 10 and Figure 11The storage component includes a mounting plate 7 and two trays 8 fixedly mounted on the mounting plate 7. The two trays 8 are connected by two side plates 9. The adjustment structure includes a first control box 10 located on the side of the mounting plate 7 away from the trays 8. A third rotating shaft 51 is rotatably connected inside the first control box 10. The third rotating shaft 51 is fixedly connected to the corresponding mounting plate 7. A transfer mechanism for driving the first control box 10 to revolve and change the tilt angle of the first control box 10 is installed on the testing table 1. A flipping mechanism for driving the third rotating shaft 51 to rotate 180 degrees is installed on the first control box 10. The transfer mechanism includes a mounting base 12 fixedly mounted on the testing table 1. A servo motor 13 is fixedly connected to the bottom of the mounting base 12. The output end of the servo motor 13 is fixedly connected to... A rotating disk 11 is located above the mounting base 12. A rotating seat 15 is fixedly connected to the first control box 10. A first rotating shaft 16 is fixedly connected to the end of the rotating seat 15 away from the first control box 10. A first support part 14 is rotatably sleeved on the outside of the first rotating shaft 16, and the first support part 14 is fixedly connected to the rotating disk 11. A first torsion spring 17 is sleeved on the outside of the first rotating shaft 16, and the two torsion arms of the first torsion spring 17 are fixedly connected to the rotating seat 15 and the first support part 14, respectively. The mounting base 12 is provided with a supporting member adapted to the rotating seat 15. The supporting member includes three first arc-shaped seats 18 fixedly installed above the mounting base 12. A second arc-shaped seat 19 is provided between two adjacent first arc-shaped seats 18. Two separate supporting members are fixedly connected to the mounting base 12. A first hydraulic telescopic rod 20 cooperates with the first belt conveyor 2 and the second belt conveyor 3. The telescopic ends of the two first hydraulic telescopic rods 20 are respectively fixedly connected to two of the second arc-shaped seats 19. The bottom of the other second arc-shaped seat 19 is fixedly connected to two movable columns 21. The movable columns 21 pass through the mounting base 12. The bottom end of the movable column 21 is fixedly connected to a fixed plate 22 that contacts the bottom of the mounting base 12. A compression spring 23 is sleeved on the outside of the movable column 21, and the two ends of the compression spring 23 abut against the bottom of the second arc-shaped seat 19 and the top of the mounting base 12, respectively. A presser for pressing the tilted first control box 10 located above the second belt conveyor 3 is installed on the testing table 1. The presser includes a mounting bracket 3 fixedly installed on the testing table 1. 5. The end of the mounting bracket 35 is rotatably connected to the rotating disk 11. A second hydraulic telescopic rod 33 is fixedly connected to the mounting bracket 35. The telescopic end of the second hydraulic telescopic rod 33 is fixedly connected to a pressing block 34 for pressing the first control box 10 to tilt. The flipping mechanism includes a first gear 24 fixedly mounted on the third rotating shaft 51. A movable frame 25 passes through the first control box 10. The top of the movable frame 25 is located below the pressing block 34. A plurality of tension springs 26 are provided inside the first control box 10. The top of the tension springs 26 is fixedly connected to the top of the inner wall of the first control box 10. The bottom of the tension springs 26 passes through the first control box 10 and is fixedly connected to the movable frame 25. The bottom of the first control box 10 abuts against the movable frame 25.A first toothed plate 27, which meshes with the first gear 24, is fixedly connected to the movable frame 25;

[0046] The servo motor 13 drives the rotating disk 11 to rotate. The rotating disk 11 drives the first control box 10 to rotate synchronously via the first support part 14, the first rotating shaft 16, and the rotating seat 15. The first control box 10 drives the mounting plate 7, the support plate 8, and the side plate 9 to rotate to one side of the first belt conveyor 2 via the third rotating shaft 51. The rotating seat 15 slides from the first arc-shaped seat 18 to above the second arc-shaped seat 19 located on one side of the first belt conveyor 2. The first torsion spring 17 applies a force to the rotating seat 15 so that the rotating seat 15 is always in close contact with the top of the first arc-shaped seat 18 or the second arc-shaped seat 19. The height of the support plate 8 facing the first belt conveyor 2 is higher than the height of the support plate 8 facing the mounting plate 7. The support plate 8 is in an inclined state. At this time, it is located on the first belt conveyor. The first hydraulic telescopic rod 20 on one side of the conveyor 2 drives the corresponding second arc-shaped seat 19 to move downwards. The tilt angle of the rotating seat 15 and the first control box 10 on one side of the first belt conveyor 2 changes, and the height of the end of the pallet 8 away from the mounting plate 7 decreases, eventually bringing the end of the pallet 8 into contact with the first belt conveyor 2. The first belt conveyor 2 drives the connector to slide between the two side plates 9 via the pallet 8, and finally the connector abuts against the mounting plate 7. At this time, the first hydraulic telescopic rod 20 drives the second arc-shaped seat 19 to return to its initial height, so that the top horizontal position of the second arc-shaped seat 19 is consistent with the top horizontal position of the first arc-shaped seat 18. The servo motor 13 drives the rotating disk 11 to rotate, so that the connector located between the two side plates 9 moves from the first... The first belt conveyor 2 moves above the third belt conveyor 4. When the connector above the third belt conveyor 4 is defective, the second arc-shaped seat 19 is driven to move downward by the first hydraulic telescopic rod 20 on one side of the third belt conveyor 4. This changes the tilt angle of the first control box 10 above the third belt conveyor 4, ultimately making the height of the end of the pallet 8 away from the mounting plate 7 lower than the height of the end of the pallet 8 facing the mounting plate 7. This allows the connector on the pallet 8 to slide onto the third belt conveyor 4. When no defects are found in the connector above the third belt conveyor 4, the first hydraulic telescopic rod 20 on one side of the third belt conveyor 4 stops driving the second arc-shaped seat 19 to move vertically. The top of the second arc-shaped seat 19... The horizontal position and the top horizontal position of the first arc-shaped seat 18 are always consistent. The servo motor 13 drives the rotating disk 11 to rotate again, so that the rotating seat 15 slides again on the second arc-shaped seat 19 and the first arc-shaped seat 18. When the connector rotates to the top of the second belt conveyor 3, the rotating seat 15 rotates to the top of the second arc-shaped seat 19 corresponding to the movable column 21. The second hydraulic telescopic rod 33 drives the pressing block 34 to move. The pressing block 34 contacts the movable frame 25 and pushes the movable frame 25 to slide relative to the first control box 10. The tension spring 26 is in the tension state, and the movable frame 25 drives the first toothed plate 27 to move. The first toothed plate 27 can then drive the mounting plate 7 to rotate 180 degrees through the first gear 24 and the third rotating shaft 51.When the mounting plate 7 rotates 180 degrees, the top of the first control box 10 and the movable frame 25 abut against each other. As the pressing block 34 continues to move, the pressing block 34 drives the movable frame 25, the first control box 10, and the rotating seat 15 to change their tilt angles synchronously. The rotating seat 15 pushes the corresponding second arc-shaped seat 19, movable column 21, and fixed plate 22 to move downwards. The compression spring 23 is in a compressed state. Finally, the height of the end of the support plate 8 away from the mounting plate 7 is lower than the height of the end of the first support plate 8 facing the mounting plate 7. The connector on the support plate 8 can then slide onto the second belt conveyor 3. When the second hydraulic telescopic rod 33 drives the pressing block 34 to move in the opposite direction, the compression spring 23 pushes the second arc-shaped seat 19. As column 9 and movable column 21 move upward, rotating seat 15 rotates in the opposite direction relative to first support part 14, and finally the top of fixed plate 22 and the bottom of rotating plate 11 abut together. The top horizontal position of second arc-shaped seat 19 is consistent with the top horizontal position of first arc-shaped seat 18. First control box 10 and rotating seat 15 maintain their tilt angle at this time. As pressing block 34 continues to move, tension spring 26 drives movable frame 25 to follow pressing block 34. Movable frame 25 drives first gear 24 to rotate in the opposite direction through first toothed plate 27. When the bottom of first control box 10 abuts against movable frame 25 again, mounting plate 7, support plate 8 and side plate 9 rotate in the opposite direction relative to first control box 10 to their initial positions.

[0047] Example 3, based on Example 2, by Figure 2 , Figure 7 , Figure 8 and Figure 9 As shown, a first iron plate 28 is provided between two side plates 9, and a first sliding plate 29 is fixedly connected to the first iron plate 28. The first sliding plate 29 passes through a corresponding side plate 9, and a first magnet block 30 that contacts the first iron plate 28 is fixedly connected to the side plate 9. An arc-shaped plate 31 that is adapted to the first sliding plate 29 is fixedly connected to the first control box 10. An anti-detachment strip 32 is fixedly connected to the end of the first sliding plate 29 away from the first iron plate 28.

[0048] When the mounting plate 7, support plate 8, and side plate 9 rotate relative to the first control box 10 to flip the connector, the first iron plate 28 rotates from the side of the connector to below it, and the side plate 9 drives the first sliding plate 29 to rotate synchronously. The end of the first sliding plate 29 contacts the arc plate 31, and the first sliding plate 29 slides on the arc plate 31. The arc plate 31 pushes the first sliding plate 29 to slide relative to the side plate 9. The first iron plate 28 is no longer in contact with the first magnet block 30, and the first iron plate 28 pushes the connector to move relative to the two side plates 9. When the mounting plate 7, support plate 8, and side plate 9 rotate 100 degrees... At 80 degrees, the first iron plate 28 pushes the connector to be centered relative to the two side plates 9. When the support plate 8 is tilted, it is easy for the connector to slide onto the second belt conveyor 3. When the mounting plate 7, support plate 8 and side plate 9 rotate in opposite directions, the end of the first slide plate 29 slides on the arc plate 31. At this time, the first slide plate 29 and the first iron plate 28 slide in opposite directions relative to the side plate 9 due to gravity. Finally, the first iron plate 28 is magnetically attracted to the first magnet block 30 again. The first iron plate 28 and the first slide plate 29 return to their initial positions relative to the side plate 9. The design of the anti-detachment strip 32 prevents the first slide plate 29 from detaching from the side plate 9.

[0049] Example 4, based on Example 2, by Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The obstacle avoidance assembly includes a swing base 39 fixedly mounted on the top of the fifth detection camera 38. A support block 40 for contacting the connector to be detected is fixedly connected to the swing base 39. A second rotating shaft 41 is fixedly connected through the swing base 39. A second support portion 42 is rotatably sleeved on the outside of the second rotating shaft 41, and the second support portion 42 is fixedly connected to the detection table 1. A second torsion spring 43 is sleeved on the outside of the second rotating shaft 41. The two torsion arms of the second torsion spring 43 are fixedly connected to the swing base 39 and the second support portion 42, respectively. A second control box 44 is rotatably connected to both ends of the second rotating shaft 41, and the second control box 44 is fixedly connected to the detection table 1. The control box 44 is equipped with a positioning component for positioning the second rotating shaft 41. The positioning component includes a second magnet block 46 fixedly installed at the bottom of the second control box 44. The bottom of the second magnet block 46 contacts a second iron plate 47. A support frame 48 located above the pallet 8 is provided above the first belt conveyor 2. The two ends of the second rotating shaft 41 are respectively fixedly connected to the second gear 49. The second control box 44 is provided with a second toothed plate 50 that meshes with the second gear 49. The top of the second iron plate 47 and the support frame 48 are connected by several second slide plates 45. The second slide plates 45 pass through the second control box 44, and the second toothed plate 50 and a corresponding second slide plate 45 are fixedly connected.

[0050] When the first belt conveyor 2 drives the connector to move to one side of the fifth detection camera 38, the connector contacts the support block 40. The first belt conveyor 2 drives the support block 40, the swing seat 39, the fifth detection camera 38, and the second rotating shaft 41 to rotate relative to the second support part 42 through the connector. The second rotating shaft 41 drives the second toothed plate 50 and the second slide plate 45 to move down through the second gear 49, so that the second iron plate 47 is no longer in contact with the bottom of the second magnet block 46, thus releasing the restriction on the position of the fifth detection camera 38. At this time, the second torsion spring 43 drives the second rotating shaft 41, the swing seat 39, and the fifth detection camera 38 to rotate. The second torsion spring 43 gradually recovers its deformation, and finally the bottom of the support frame 48 abuts against the top of the second control box 44, and the fifth detection camera 38 is no longer located in the connection. On one side of the device, the first belt conveyor 2 can drive the connector to pass under the fifth detection camera 38. When the connector slides onto the storage piece, the tilt angle of the first control box 10 is changed by the transfer mechanism so that the tilt angles of the first control box 10 drive the mounting plate 7, the support plate 8 and the side plate 9 to change synchronously. The support plate 8 lifts the support frame 48, the second slide plate 45 and the second iron plate 47 to move upward. The second slide plate 45 drives the second gear 49 to rotate in the opposite direction through the second toothed plate 50 so that the second torsion spring 43 deforms. Finally, the top of the second iron plate 47 contacts the second magnet block 46 again. The second magnet block 46 applies magnetic force to the second iron plate 47 so that the fifth detection camera 38 is reset to the initial position and the fifth detection camera 38 remains fixed relative to the second control box 44.

[0051] This embodiment also provides a connector appearance inspection process, applied to the connector appearance inspection device described above, including the following steps:

[0052] Step 1: The connector to be inspected is transported to the area below the first inspection camera 5 by the first belt conveyor 2. The top surface of the connector is inspected by the first inspection camera 5. The connector is simultaneously located between two third inspection cameras 36. The two adjacent third inspection cameras 36 inspect both sides of the connector. The first belt conveyor 2 drives the connector to move toward the fifth inspection camera 38.

[0053] Step 2: The connector facing the fifth detection camera 38 is detected by the fifth detection camera 38. When the connector moves to the preset position, the fifth detection camera 38 is driven by the avoidance component to avoid the moving connector. The first belt conveyor 2 transports the connector to the storage component. The avoidance component drives the fifth detection camera 38 to reset to the initial position.

[0054] Step 3: The storage component is moved above the third belt conveyor 4 by adjusting the structure. The last side of the connector is inspected by the fourth detection camera 37 located above the third belt conveyor 4. At the same time, the next empty storage component is moved to one side of the first belt conveyor 2 by adjusting the structure. The next connector can be stored in the storage component. When there are defects on the top and four sides of the connector, the connector on the storage component is slid onto the third belt conveyor 4 by adjusting the structure. When there are no defects on the top and four sides of the connector, the connector on the storage component is moved above the second belt conveyor 3 by adjusting the structure.

[0055] Step 4: Adjust the structure to drive the storage component to rotate 180 degrees so that the side of the connector that was originally located below faces upward. By adjusting the structure to drive the storage component, the connector slides onto the second belt conveyor 3. The second belt conveyor 3 drives the connector to move below the second detection camera 6, so that the side of the connector that was originally located below can be detected by the second detection camera 6.

[0056] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the invention is limited to these examples; within the framework of the invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity.
