[0002] With technological advancements and changing market demands, HDMI connector standards and specifications are constantly being updated. For example, HDMI 2.1 supports higher bandwidth and higher resolution. This means that test units must be able to adapt to new test standards to ensure the quality of new HDMI connectors.

[0003] At present, some small manufacturers have begun to use automated equipment to replace manual inspection of HDMI connectors. Because the production environment is more complex than that of standard manufacturers, dust is more likely to enter the production process. This dust will form residues on the contact surface of the wave pin (the wave pin is also called "shrapnel" or "spring contact"), making it impossible for the visual inspection system to accurately identify the status of the wave pin, resulting in incorrect judgment. Summary of the Invention

[0009] Furthermore, the visual inspection component includes a detection camera fixedly connected to the end of the first telescopic member, and the detection camera is provided with a lighting lamp, and the lighting lamp cooperates with the detection camera.

[0010] In order to improve the detection accuracy of the visual detection component, preferably, an air jet plate is fixedly connected to the side wall of the working box, and an air jet hole is opened on the air jet plate, and the air jet end of the air jet hole faces the connector interface.

[0011] Furthermore, the negative pressure adsorption component includes a negative pressure box fixedly connected to the end of the second telescopic member, and the negative pressure channel is arranged in the cavity of the negative pressure box. When the second telescopic member drives the negative pressure box to move toward the connector interface, the connector interface is covered by the negative pressure channel.

[0014] Furthermore, the support block is rotatably connected to a rotating shaft, the rotating shaft is fixedly connected to a transmission gear, and racks are provided on both sets of movable plates, and the racks are meshed with the transmission gear.

[0015] A connector detection method, the operating steps are as follows:

[0016] Step 1: Fix the position of the connector and position the connector interface upwards;

[0017] Step 2: Apply negative pressure to the inside of the connector interface through the negative pressure channel on the negative pressure adsorption component;

[0020] Compared with the prior art, the present invention provides a connector detection unit, device, and method, which have the following beneficial effects:

[0021] 1. This connector inspection equipment uses a visual inspection component to primarily photograph and inspect the shape of the internal waveguide pins of the connector interface, thereby inferring whether the internal waveguide pins are in good condition. The negative pressure adsorption component primarily absorbs and removes dust and impurities inside the connector interface, reducing the amount of dust remaining on the waveguide pins and preventing dust from affecting their shape.

It can start from the outside of the connector interface and gradually blow inward to blow away the dust remaining on the wave pin, so that the subsequent negative pressure adsorption can be more convenient. At the same time, it can also make the inspection camera clearer when taking pictures of the wave pin, so that the inspection camera can accurately identify the status of the wave pin and prevent the phenomenon of misjudgment;

[0024] 4. The connector detection device activates the switches of the second telescopic member and the negative pressure pump, so that the negative pressure channel of the negative pressure box covers the interface of the connector, so that the negative pressure channel further absorbs and removes dust in the connector interface;

[0025] 5. In order to improve the stability of the connection detection component during connection, the connector detection equipment is provided with a clamping limit mechanism on the installation box. The clamping limit mechanism can limit the position of the connector joint to prevent the connector joint and the connection detection component from shaking when connected.

[0026] The parts not involved in the device are the same as the existing technology or can be implemented by existing technology. The present invention can blow away the dust remaining on the wave needle so that subsequent negative pressure adsorption can be more convenient. At the same time, it can also make the detection camera clearer when taking pictures of the wave needle, so that the detection camera can accurately identify the state of the wave needle and prevent the occurrence of misjudgment.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0038] Example 1:

[0039] Reference Figures 1-8 A detection unit for a connector includes a detection mechanism, which is used to detect the connector interface. The detection mechanism includes: a visual detection component, a negative pressure adsorption component and a connection detection component.

[0040] The above-mentioned visual inspection component mainly takes photos to detect the shape of the wave needle inside the connector interface, and then infers whether the condition of the internal wave needle is good; the negative pressure adsorption component mainly absorbs and removes dust and impurities inside the connector interface, reducing the amount of residual dust on the surface of the wave needle and preventing dust from affecting the shape of the wave needle, so that the visual inspection system can more accurately identify the status of the wave needle and prevent wrong judgment.

[0041] The above-mentioned connection detection component mainly detects the performance of the wave needle in the connector interface. When the contact end of the connection detection component is engaged with the connector interface, the connection detection component and the connector interface are electrically coordinated, and then the wave needle is detected by the interface status detection sensor, and the contact resistance between the wave needle and the interface status detection sensor contacts is measured to ensure the stability of the wave needle signal transmission. The sensor can also be used to detect the insertion status of the connector connector to determine whether the connector connector is fully inserted. This can be achieved through a photoelectric sensor, a pressure sensor or a switch to ensure that the wave needle can make good contact with the inserted device, and then the plug-in status is fed back through the LED indicator or display screen, and a warning of poor connection or wave needle contact failure is immediately issued to remove it.

[0042] A lighting component is provided on one side of the detection end of the visual detection component. The lighting component can be an LED light group to provide a light source for the visual detection component. A negative pressure channel is provided on the negative pressure adsorption component, and the cross-sectional area of ​​the negative pressure channel is larger than the cross-sectional area of ​​the connector interface. When the connector interface extends to the inside of the negative pressure channel, the negative pressure airflow adsorbs impurities inside the connector interface, and then adsorbs and cleans the residual dust inside the interface.

[0043] A clamping and limiting mechanism is also provided on the detection mechanism. When the contact end of the connection detection component is engaged with the connector interface, the clamping end of the clamping and limiting mechanism abuts against the outer wall of the connector, thereby ensuring the stability of the connector interface during insertion.

[0044] Example 2:

[0045] A detection device for a connector includes a support platform 1, on which a mounting box 2 is fixedly connected, and a first screw rod 3 is rotatably connected inside the mounting box 2, and the first screw rod 3 is a bidirectional screw rod, and a first movable block 5 is also threadedly connected to the first screw rod 3, and two groups of first movable blocks 5 are provided. When the first screw rod 3 rotates clockwise or counterclockwise, the two groups of first movable blocks 5 move relative to or oppositely, and a movable splint 6 is also fixedly connected to the first movable block 5 for clamping the outer wall of the connector, and a first motor 4 is also fixedly connected inside the mounting box 2, and the first screw rod 3 is fixedly connected to the output end of the first motor 4, and the first motor 4 can drive the first screw rod 3 to rotate.

[0046] In addition, a working box 7 is fixedly connected to the installation box 2, a working plate 8 is slidably connected to the working box 7, and the detection mechanism is connected to the working plate 8 via a telescopic member.

[0047] The telescopic member can be an electric telescopic rod, and the electric telescopic rod is fixedly connected to the working plate 8, and the detection mechanism is arranged on the output end of the electric telescopic rod.

[0048] The detection mechanism includes: a visual detection component, a negative pressure adsorption component and a connection detection component.

[0049] The above-mentioned visual inspection component includes a detection camera 9 fixedly connected to the end of the first telescopic member. The detection camera 9 is provided with a lighting lamp 10, and the lighting lamp 10 cooperates with the detection camera 9. The detection camera 9 usually uses a CCD or CMOS camera, which usually has high resolution and good image quality, and the lighting lamp 10 is used in conjunction with the detection camera 9 to ensure that the details of the wave needle are clearly visible in the image.

[0050] In order to drive the working plate 8 to move back and forth on the working box 7, a second screw rod 23 is also rotatably connected in the working box 7, and a second movable block 25 is threadedly connected to the second screw rod 23, and a connecting plate 26 is fixedly connected to the second movable block 25, and a slide groove is opened on the side wall of the working box 7, and the connecting plate 26 is slidably connected to the slide groove, and the working plate 8 is fixedly connected to the connecting plate 26, and a second motor 24 is also fixedly connected in the working box 7, and the second screw rod 23 is fixedly connected to the output end of the second motor 24. When the second motor 24 is started, it can drive the second screw rod 23 to rotate in the working box 7, and then drive the second movable block 25 to move back and forth in contact with the inner wall of the working box 7, thereby adjusting the position of the working plate 8.

[0051] In addition, an air jet plate 12 is fixedly connected to the side wall of the working box 7, and an air jet hole is opened on the air jet plate 12, and the air jet end of the air jet hole faces the connector interface.

[0052] The connector interface can be purged through the jet holes on the jet plate 12, and the dust that may remain on the wave needle in the interface can be purged, and the dust on the surface of the wave needle can be blown away. It can start from the outside of the connector interface and gradually blow inward to blow away the dust remaining on the wave needle, so that the negative pressure adsorption can be more convenient in the future, and at the same time, it can also make the detection camera 9 clearer when taking pictures of the wave needle.

[0053] Furthermore, the above-mentioned negative pressure adsorption component includes a negative pressure box 11 fixedly connected to the end of the second telescopic member, and the negative pressure channel is arranged in the cavity of the negative pressure box 11. When the second telescopic member drives the negative pressure box 11 to move toward the connector interface, the connector interface is covered by the negative pressure channel.

[0054] In order to facilitate providing a negative pressure effect in the cavity of the negative pressure box 11, a negative pressure pump 35 is also provided in the working box 7. An air intake pipe is also provided on the input end of the negative pressure pump 35, and the air intake pipe is connected to the negative pressure box 11. When the negative pressure pump 35 is started, the residual dust in the cavity of the negative pressure box 11 can be adsorbed, and the gas is discharged into the outside air through the output end of the negative pressure pump 35.

[0055] In order to detect the performance of the wave needle in the connector interface, the connection detection component includes a connection box 13 fixedly connected to the end of the third telescopic member, and an interface status detection sensor that matches the connector interface is provided in the connection box 13.

[0056] When the contact end of the connection detection component is engaged with the connector interface, the connection detection component and the connector interface are electrically coordinated, and then the wave needle is detected by the interface status detection sensor, and the contact resistance between the wave needle and the interface status detection sensor contact is measured to ensure the stability of the wave needle signal transmission.

[0057] Reference Figure 1As shown in the figure, the distribution positions of the visual detection component, the negative pressure adsorption component and the connection detection component are arranged, and the open end of the negative pressure box 11 on the negative pressure adsorption component faces the interface of the connector, and the jet end of the jet plate 12 always faces the interface of the connector. When it is necessary to detect the wave needle in the connector interface, the position of the working plate 8 is first changed, and the position of the negative pressure box 11 is changed. The working plate 8 is moved to the right, and the detection camera 9 is moved to the top of the connector interface. During this process, the jet end of the jet plate 12 always blows air toward the interface of the connector, and the dust in the interface is blown out for the first time. Then the position of the negative pressure box 11 is changed again, and the working plate 8 is moved to the left, so that the position of the negative pressure box 11 faces the top of the connector interface. Then the switch of the second telescopic part and the negative pressure pump 35 is started, so that the negative pressure channel of the negative pressure box 11 covers the interface of the connector, so that the negative pressure channel further adsorbs and removes dust in the connector interface.

[0058] Then move the working plate 8 to the right to move the detection camera 9 to the top of the connector interface. During this process, the jet end of the jet plate 12 blows air toward the interface of the connector for a second time to blow away the dust in the interface again and reduce the residual dust on the wave needle. At this time, start the switch of the first telescopic part again to make the first telescopic part drive the detection camera 9 to move to the top of the interface, and then start the switch of the lighting lamp 10, so that the detection camera 9 can accurately identify the state of the wave needle to prevent the occurrence of wrong judgment.

[0059] Furthermore, in order to provide gas to the jet plate 12, a booster cylinder 27 is fixedly connected to the working box 7, and a booster rod 28 is slidably connected to the booster cylinder 27, and a piston is provided at one end of the booster rod 28, and the piston is in contact with the inner wall of the booster cylinder 27, and the other end of the booster rod 28 is fixedly connected to the second movable block 25. An air inlet pipe and an air outlet pipe are also respectively provided on the booster cylinder 27, and a one-way valve is provided on the air inlet pipe and the air outlet pipe. When the detection camera 9 moves to the top of the connector interface, the booster rod 28 will drive the piston to move during this process, pressurize the gas inside the booster cylinder 27, and transport the gas to the jet plate 12 through the outlet pipe. When the booster rod 28 is reset, it will drive the piston to reset, thereby refilling the gas in the booster cylinder 27.

[0060] When the detection camera 9 has passed the shape detection of the wave needle, the connection detection component is used to detect the connection of the connector interface. In order to improve the stability of the connection detection component during connection, a clamping limit mechanism is provided on the installation box 2, and the position of the connector joint can be limited by the clamping limit mechanism.

[0061] The above-mentioned clamping and limiting mechanism is arranged on the installation box 2, and the clamping and limiting mechanism includes a clamping plate 20, and an inflatable air cushion 21 is connected to the limiting surface of the clamping plate 20. The installation box 2 is fixedly connected to a support block 14, and the support block 14 is fixedly connected to a limiting plate 17. A first movable plate 18 is slidably connected to one limiting plate 17, and a second movable plate 19 is slidably connected to the second limiting plate 17. The clamping plates 20 are respectively arranged on the first movable plate 18 and the second movable plate 19, and the limiting surfaces of the two groups of clamping plates 20 are arranged opposite to each other.

[0062] The outer wall of the connector can be clamped by two groups of clamping plates 20 to prevent the connector joint and the connection detection component from shaking when connected. In order to facilitate the convenient movement of the position of the first movable plate 18 and the second movable plate 19, a support block 14 is fixedly connected to the installation box 2, and a limiting plate 17 is fixedly connected to the support block 14. The first movable plate 18 is slidably connected to one limiting plate 17, and the second movable plate 19 is slidably connected to the second limiting plate 17. The clamping plates 20 are respectively arranged on the first movable plate 18 and the second movable plate 19, and the rotating shaft 15 is rotatably connected to the support block 14, and the rotating shaft 15 is fixedly connected to the transmission gear 16, and racks are provided on both groups of movable plates, and the racks are meshed with the transmission gear 16.

[0063] When the rotating shaft 15 drives the transmission gear 16 to rotate, it can drive the first movable plate 18 and the second movable plate 19 to move toward each other on the two sets of limit plates 17. They can move in opposite directions or in reverse directions. When moving in opposite directions, the two sets of clamping plates 20 can press against the outer wall of the connector. During this process, the inflatable air cushion 21 is inflated and expanded, thereby improving the friction effect of the clamping plate 20, making the connector more stable during detection.

[0064] In order to facilitate the movement of the clamping plate 20, a fixed block 32 is also fixedly installed in the working box 7, and a transmission rod 33 is rotatably connected to the fixed block 32, and a second pulley 34 is fixedly connected to the transmission rod 33, and the first pulley 22 is also fixedly connected to the rotating shaft 15, and the first pulley 22 is then connected to the second pulley 34 through a belt, and a connecting shaft 30 is also rotatably connected in the working box 7, a connecting gear 31 is provided on the connecting shaft 30, and the transmission rod 33 is meshed with the connecting shaft 30 through a bevel gear for transmission, and a meshing plate 29 is also fixedly connected to the second movable block 25, and the meshing plate 29 is meshed with the connecting gear 31, and an air cylinder 36 is also fixedly connected in the working box 7, and an air cylinder 36 is also slidably connected to the air cylinder 36. A piston is provided at one end of the air cylinder 37, and the piston is in contact with the inner wall of the air cylinder 36, and the other end of the air cylinder 37 is fixedly connected to the meshing plate 29.

[0065] When the connecting box 13 moves to the top of the connector interface, the second movable block 25 drives the meshing plate 29 to move, and then the meshing plate 29 drives the connecting gear 31 to rotate, and then the connecting gear 31 drives the connecting shaft 30 to rotate synchronously, and then the connecting shaft 30 drives the rotating shaft 15 to rotate, so that the two sets of clamping plates 20 clamp the outer wall of the connector. During this process, the gas supply rod 37 will drive the piston to move on the inner wall of the gas supply cylinder 36, and transport the gas in the gas supply cylinder 36 to the inflatable air cushion 21 through the outlet pipe, so that the inside of the inflatable air cushion 21 is inflated and expanded, thereby improving the friction effect between the inflatable air cushion 21 and the outside of the connector.

[0067] Step 1: Fix the position of the connector and position the connector interface upwards;

[0068] Step 2: Apply negative pressure to the inside of the connector interface through the negative pressure channel on the negative pressure adsorption component;

[0069] Step 3: Use the inspection end on the visual inspection component to visually inspect the internal wave needle of the connector interface, and cooperate with the lighting component to improve the inspection accuracy of the inspection end, and check whether it is qualified;
