Abstract
Description
Technical Field
[0001] This invention relates to the field of connector testing technology, and in particular to a connector quality testing device based on optical testing. Background Technology
[0002] In today's highly integrated and intelligent electronic devices, connectors, as key components for electrical connections and signal transmission, directly affect the stability and reliability of the entire electronic system. Therefore, rigorous and comprehensive quality testing of connectors is essential.
[0003] Traditional connector quality inspection methods have many limitations. Current inspection methods typically focus only on a single performance indicator of the connector. Therefore, a single inspection method often results in a cumbersome inspection process, usually requiring different inspection steps to be performed separately. This not only consumes a lot of time and reduces inspection efficiency, but may also introduce additional errors due to multiple clamping, affecting the accuracy of the inspection results.
[0004] Furthermore, the pressure applied when the connector plug is inserted into the socket during the connector mating process cannot be monitored. This insertion pressure is crucial for determining whether the mating process meets acceptance requirements. However, traditional testing methods struggle to accurately capture this critical information, making it impossible to promptly identify and resolve potential quality issues. Moreover, existing optical testing equipment is rarely effectively integrated with pressure detection mechanisms, failing to cross-verify connector mating quality from both mechanical and optical perspectives. This makes it difficult to meet the stringent requirements of modern electronic equipment for high-quality, high-reliability connector testing.
[0005] In summary, it is now necessary to design a connector quality inspection device based on optical testing. Summary of the Invention
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an optical testing-based connector quality inspection device.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: An optical testing-based connector quality inspection device includes: A base, wherein the upper end of the base is provided with a rotating groove; A mounting bracket is fixed to the upper end of the base; Two material placement mechanisms are located above the rotating groove for placing connector plugs and connector sockets; A reversing mechanism is located inside the trough, and both feeding mechanisms are mounted on the reversing mechanism; A movable plate is disposed below the fixed frame, and a second detection camera is provided at the lower end of the movable plate; A drive mechanism is mounted on the fixed frame and connected to the movable plate. The drive mechanism has two strokes in the vertical direction. An internal detection mechanism is located on the side wall of the moving plate and is connected to the drive mechanism. An insertion detection mechanism is provided at the lower end of the movable plate and is connected to the drive mechanism; Specifically, after the first segment of the downward movement of the drive mechanism is completed, the internal detection mechanism can be moved between the connector plug and connector socket to be detected by the moving plate. The internal detection mechanism can then detect and record the internal components of the connector plug and connector socket. During the second segment of the downward movement of the drive mechanism, the internal detection mechanism can be moved out from between the connector plug and connector socket to make room. At the same time, the insertion detection mechanism can be driven to complete the insertion of the connector plug and connector socket. The insertion detection mechanism and the second detection camera can then detect and record the results.
[0008] As a further improvement of the present invention, the driving mechanism includes an electric push rod mounted on the top of the fixed frame. The telescopic end of the electric push rod passes downward through the fixed frame and is fixedly connected to a connecting plate. A connecting rod is fixed to the lower end of the connecting plate.

One end of the third spring is connected to the connecting rod, and the other end of the third spring is connected to the inner wall of the connecting sleeve. A pressure switch is provided at the upper end of the connecting plate.
[0009] As a further improvement of the present invention, the internal detection mechanism includes a mounting sleeve fixed to the side wall of the movable plate. A movable rod is slidably inserted at the end of the mounting sleeve away from the movable plate. A first detection camera is installed at the end of the movable rod away from the mounting sleeve. A traction rope is fixed at the end of the movable rod located inside the mounting sleeve. The end of the traction rope away from the movable rod passes through the mounting sleeve and is fixed to the side wall of the connecting plate. A second spring is provided inside the mounting sleeve and fitted outside the traction rope. One end of the second spring is connected to the movable rod, and the other end of the second spring is connected to the inner wall of the mounting sleeve. Two first guide wheels are installed on the outer wall of the mounting sleeve. A second guide wheel is installed at the upper end of the movable plate. The traction rope passes around the first guide wheels and the second guide wheels.
[0010] As a further improvement of the present invention, the insertion detection mechanism includes a laser emitter and a laser receiver. Movable sleeves are fitted around the outer sides of both the laser emitter and the laser receiver. The laser emitter, laser receiver, and movable sleeves are connected via annular pressure sensors. Two support structures are provided at the lower end of the moving plate. The two movable sleeves are respectively disposed inside the two support structures. Each support structure includes an L-shaped rod fixed to the lower end of the moving plate. A movable groove is provided at the end of the L-shaped rod away from the moving plate. The movable sleeve is slidably disposed inside the movable groove. A strip-shaped groove is provided through the inner top wall of the movable groove. An inclined rod is rotatably connected to the upper side wall of the movable sleeve. The inclined rod passes through the strip-shaped groove. A vertical rod is rotatably connected to the end of the inclined rod away from the movable sleeve. The end of the vertical rod away from the inclined rod passes through the moving plate and is fixed to the lower end of the connecting plate. The vertical rod is slidably connected to the moving plate.
[0011] As a further improvement of the present invention, the reversing mechanism includes a turntable disposed inside the rotating groove, a receiving groove provided at the bottom of the base, a rotating column fixed at the lower center of the turntable, the rotating column penetrating the inner bottom wall of the rotating groove and extending into the receiving groove, and the rotating column being rotatably connected to the inner bottom wall of the rotating groove, a reversing motor installed inside the receiving groove, the output shaft of the reversing motor being fixed at the lower end of the rotating column, and the reversing motor being electrically connected to a pressure contact switch.
[0012] As a further improvement of the present invention, the material placement mechanism includes a placement platform fixed to the upper end of the turntable. A plug placement seat and a socket placement seat are provided above the placement platform. Insertion holes are provided through the side walls of the plug placement seat and the socket placement seat. Two guide grooves are provided at the upper end of the placement platform. Guide blocks are slidably provided inside the two guide grooves. The two guide blocks are respectively fixed to the bottom of the plug placement seat and the socket placement seat. Guide rods are slidably connected to the guide blocks through the two guide blocks. Both ends of the guide rods are fixed to the inner walls of the guide grooves. A first spring is fitted on the guide rod. One end of the first spring is connected to the inner wall of the guide groove, and the other end of the first spring is connected to the guide block.
[0013] As a further improvement of the present invention, two fixing plates are fixed on the inner top wall of the fixing frame, and each of the two fixing plates is provided with a moving groove on its side wall. The left and right ends of the moving plates are respectively slidably connected to the inside of the two moving grooves.
[0014] As a further improvement of the present invention, the first detection camera is a dual-head camera.
[0015] The beneficial effects of this invention are: 1. Through a unique two-stage stroke design of the drive mechanism, internal detection and insertion detection are integrated into a single up-and-down process. In one action cycle, the internal condition, mating process, insertion pressure and laser continuity of the connector plug and connector socket can be completed in a coordinated manner, realizing a multi-dimensional and integrated optical detection process, which significantly improves the comprehensiveness and efficiency of the detection.
[0016] 2. During the second downward stroke of the drive mechanism, the downward movement of the connecting plate, through the precise cooperation of the traction rope with the second and first guide wheels, pulls the movable rod to overcome the elastic force of the second spring and retract it into the mounting sleeve rod. This allows the first detection camera to smoothly withdraw from between the connector plug and the connector socket, preventing collision damage or image interference during the insertion process. This design cleverly utilizes a single power source to achieve active avoidance of the detection probe, effectively avoiding detection interference and ensuring the accuracy of the detection position.
[0017] 3. The downward movement of the connecting plate, through the linkage structure formed by the vertical rod and the diagonal rod, converts the vertical motion into a horizontal thrust that is movably sleeved in the movable groove of the L-shaped rod. This smoothly and synchronously pushes the laser emitter and laser receiver to extend and align with the insertion axis of the plug and socket placement seats, and inserts them into the inside of the connector plug and connector socket. This mechanism has a simple structure, good transmission rigidity, and no gaps, ensuring the repeatability of the laser optical path positioning accuracy during each test, laying the foundation for stable quality judgment based on the laser transmission status.
[0018] 4. During the process of the laser transmitter and laser receiver moving to the target position, the ring pressure sensor between them and the movable sleeve will make contact with and monitor the pressure applied when the connector plug is inserted into the socket. Combined with the insertion trajectory recorded by the second detection camera, it is possible to intuitively judge whether the insertion process is smooth, whether there is any jamming or abnormal resistance. Subsequently, the laser continuity detection verifies the physical insertion from another dimension. It integrates pressure and optical dual detection mechanisms, which can cross-verify the insertion quality of the connector from both mechanical and optical levels.
[0019] 5. The reversing mechanism drives the turntable to rotate 180 degrees via a reversing motor, which can move the material loading mechanism that has completed testing away from the workstation and bring the new group to be tested into the workstation at the same time. This process is automatically triggered by the electric push rod pressing the contact switch when it moves up to the top. This allows the equipment to test another group of samples while the operator is loading materials at the testing station, realizing parallel operation of testing and loading / unloading, which significantly improves the utilization rate and production efficiency of the equipment and greatly shortens the ineffective waiting time of the equipment.

When the connecting plate 20 moves to the highest position, it contacts and presses against the fixed frame 2 through the pressure switch 21. The pressure switch 21 triggers the reversing motor 9 to start once. The reversing motor 9 rotates 180 degrees once, which in turn drives the turntable 5 to rotate 180 degrees through the rotating column 15.
[0025] The movable plate 22 is located below the fixed frame 2. The lower end of the movable plate 22 is provided with a second detection camera 43, which is used to capture the insertion process of the connector plug 11 and the connector socket 13. The first detection camera 26 is a dual-head camera, which captures the inside of the connector plug 11 and the connector socket 13. Two fixed plates 4 are fixed on the inner top wall of the fixed frame 2. The side walls of the two fixed plates 4 are provided with movable grooves 23. The left and right ends of the movable plate 22 are slidably connected to the inside of the two movable grooves 23 respectively. The movable grooves 23 can limit the movement of the movable plate 22. A drive mechanism is mounted on a fixed frame 2 and connected to a movable plate 22. The drive mechanism has two strokes in the vertical direction. The drive mechanism includes an electric push rod 3 mounted on the top of the fixed frame 2. The telescopic end of the electric push rod 3 passes through the fixed frame 2 and is fixedly connected to a connecting plate 20. The electric push rod 3 provides power to the entire drive mechanism.

[0026] An internal detection mechanism is located on the side wall of the movable plate 22 and is connected to the drive mechanism. The internal detection mechanism includes a mounting sleeve 24 fixed to the side wall of the movable plate 22. A movable rod 25 is slidably inserted into the end of the mounting sleeve 24 away from the movable plate 22. The mounting sleeve 24 provides a mounting base and guide for the movable rod 25. A first detection camera 26 is mounted on the end of the movable rod 25 away from the mounting sleeve 24. A traction rope 28 is fixed to the end of the movable rod 25 located inside the mounting sleeve 24. The end of the traction rope 28 away from the movable rod 25 passes through the mounting sleeve 24 and is fixed to the drive mechanism. On the side wall of the connecting plate 20, the traction rope 28 is used to pull the movable rod 25 to move.

The traction rope 28 passes around the first guide wheel 27 and the second guide wheel 29. The first guide wheel 27 and the second guide wheel 29 are used to change the direction of the traction rope 28.
[0027] An insertion detection mechanism is located at the lower end of the movable plate 22 and is connected to the drive mechanism. The insertion detection mechanism includes a laser emitter 40 and a laser receiver 41. The laser emitter 40 emits laser light, and the laser receiver 41 receives the laser light. The quality of the connector plug 11 and connector socket 13 is determined by detecting the transmission of the laser light. Movable sleeves 39 are fitted around the outer sides of both the laser emitter 40 and the laser receiver 41. Both the laser emitter 40 and the laser receiver 41 are connected to the movable sleeves 39 via an annular pressure sensor 42. The annular pressure sensor 42 detects the pressure during insertion of the connector plug 11 and connector socket 13. The pre-calibrated elastic resistance of the first spring 19 is removed from the detection data of the annular pressure sensor 42 to eliminate interference from the spring force of the first spring 19, thus obtaining the quality of the connector plug 11 and connector socket 13. The actual pressure data of the insertion is provided. The lower end of the movable plate 22 is provided with two support structures. Two movable sleeves 39 are respectively set inside the two support structures. The support structure includes an L-shaped rod 35 fixed to the lower end of the movable plate 22. The end of the L-shaped rod 35 away from the movable plate 22 is provided with a movable groove 36. The movable sleeve 39 is slidably set inside the movable groove 36. A strip groove 38 is provided through the inner top wall of the movable groove 36. An inclined rod 34 is rotatably connected to the upper side wall of the movable sleeve 39. The inclined rod 34 passes through the strip groove 38. The end of the inclined rod 34 away from the movable sleeve 39 is rotatably connected to a vertical rod 33. The end of the vertical rod 33 away from the inclined rod 34 passes through the movable plate 22 and is fixed to the lower end of the connecting plate 20. The vertical rod 33 is slidably connected to the movable plate 22.
[0028] In this process, after the first segment of the downward movement of the drive mechanism is completed, the internal detection mechanism can be moved between the connector plug 11 and connector socket 13 to be detected by the moving plate 22. The internal detection mechanism can detect and record the internal parts of the connector plug 11 and connector socket 13. During the second segment of the downward movement of the drive mechanism, the internal detection mechanism can be moved out from between the connector plug 11 and connector socket 13 to make room. At the same time, the insertion detection mechanism can be driven to complete the insertion action of the connector plug 11 and connector socket 13. The insertion detection mechanism and the second detection camera 43 can then detect and record the data.
[0029] When using this invention, the operator places the connector plug 11 and connector socket 13 to be tested into the plug placement seat 10 and socket placement seat 12 to complete the loading operation. Then the equipment is started, the reversing motor 9 is in standby mode, the pressure switch 21 is not triggered, the electric push rod 3 drives the connecting plate 20 and the moving plate 22 to move upward as a whole. When the connecting plate 20 presses the pressure switch 21 on the fixing frame 2, the pressure switch 21 connects the power of the reversing motor 9 to make it rotate 180 degrees. The turntable 5 then drives the two loading mechanisms to flip and change positions, so that a set of connector plugs 11 and connector sockets 13 to be tested enters the testing station, while the other loading mechanism turns away. The operator can then continue to carry out the subsequent loading operation of connector plugs 11 and connector sockets 13. Then, the first extension of the electric push rod 3 is activated to drive the connecting plate 20 to move down. During the downward movement of the connecting plate 20, the moving plate 22 will be driven to move down synchronously through the connecting rod 31, the connecting sleeve 30, and the third spring 37. When the moving plate 22 moves down to the lowest position, it will drive the first detection camera 26 to move between the connector plug 11 and the connector socket 13. The first detection camera 26 will take pictures of the inside of the connector plug 11 and the connector socket 13 and record the state of the pins or springs inside the connector plug 11 and the connector socket 13. The moving plate 22 will then carry the second detection camera 43 to the top of the connector plug 11 and the connector socket 13. Then, the electric push rod 3 extends to its second stage, continuing to move the connecting plate 20 downwards. The third spring 37 is compressed, and the downward movement of the connecting plate 20 pulls the traction rope 28. Through the cooperation of the second guide wheel 29 and the first guide wheel 27, the movable rod 25 is pulled back into the mounting sleeve 24, overcoming the elastic force of the second spring 32. This allows the first detection camera 26 to retract from between the connector plug 11 and the connector socket 13 to avoid interference. Simultaneously, the downward movement of the connecting plate 20 moves the vertical rod 33 downwards. Through the linkage structure formed by the vertical rod 33 and the diagonal rod 34, the movable sleeve 39 can be pushed to move inside the movable slot 36. The movable sleeve 39 can then move the laser emitter 40 and the laser receiver 41 closer together. The laser emitter 40 and the laser receiver 41 then extend and align with the axis of the insertion hole 14 of the plug holder 10 and the socket holder 12. Insert the connector plug 11 and connector socket 13 into the inside, then push the plug holder 10 and socket holder 12 closer together, causing the guide block 17 to move and compress the first spring 19, thus inserting the connector plug 11 and connector socket 13 into each other. The second detection camera 43 continuously records the insertion trajectory and relative position of the connector plug 11 and connector socket 13 throughout the entire insertion and removal process. During the insertion process, the pressure applied when the connector plug 11 is inserted into the socket 13 is monitored by the ring pressure sensor 42. Then, the laser emitter 40 is activated to emit a laser, and the laser receiver 41 receives the laser. The quality of the connector plug 11 and connector socket 13 can be judged by detecting the continuity of the laser transmission. It can realize full-dimensional optical detection and data recording of the internal condition of the connector plug 11 and connector socket 13, the insertion process, the insertion pressure, and the continuity of the laser.
