[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0027] As shown in the figure, a vehicle-mounted USB interface testing robot loading and unloading device includes: a moving mechanism 1, a detection mechanism 2 disposed on one side of the moving mechanism 1, and a gripping mechanism 3 disposed above the detection mechanism.

[0028] It also includes a base 4, with a detection module 22 located at the bottom of the base 4. The moving mechanism 1, the gripping mechanism 3, and the docking module are all located above the base 4. A camera is installed on the top inner side of the base 4, and a visual inspection module 22 is installed inside the camera. The visual inspection module 22 is used to inspect the socket holes on the top of the socket.

[0029] It should be noted that the base 4 is a box with two cavities on the top and bottom. A fixed plate is set in the middle of the box. The detection module 22 is fixedly connected to the bottom of the fixed plate, while other components are set on the top of the fixed plate. A camera is set on the top of the box, and a vision detection module 22 is set inside the camera. The vision detection module 22 is used to detect the sockets on the plug plate 16 in real time and determine the position of the missing parts. At the same time, two displays are set on the same side to display whether the detected interface is qualified.

[0030] The moving mechanism 1 includes: a moving component and a docking component disposed above the moving component; the moving component and the docking component are slidably connected; the docking component is used to connect with the detection mechanism 2;

[0031] In this utility model, the moving components are provided in several groups. The moving components include a moving motor 11, a pulley 12 connected to the moving motor 11, and a threaded rod connected to the pulley 12. A slide rail 13 is also provided on the outer side of the threaded rod. The pulley 12 includes a synchronous belt and a synchronous pulley meshing with the synchronous belt. The synchronous pulley is fixedly connected to the moving motor 11 and the threaded rod. The docking components include a slider 14, a connecting plate 15 disposed on the slider 14, and an insert plate 16 disposed on the slider 14. The connecting plate 15 communicates with the insert plate 16, and the insert plate 16 has several insertion holes for detection.

[0032] It should be noted that several moving components are provided and fixedly connected side by side to the base 4. The moving motor 11 is a servo motor, which can rotate in both directions and its speed can be controlled. The shaft of the moving motor 11 is fixedly connected to the pulley component 12. The pulley component 12 is a combination of a synchronous belt and two synchronous pulleys. The two synchronous pulleys are fixedly connected to the shaft of the moving motor 11 and one end of the threaded rod, respectively. A protective shell is also provided on the outside of the pulley component 12. The synchronous pulleys and the synchronous belt are located inside the protective shell. This protects the synchronous belt and the synchronous pulleys from damage by the external environment. At the same time, it prevents dust, debris or other foreign objects from entering the working area during the operation of the test robot, or prevents the connected wires from getting tangled on the synchronous belt, or getting stuck between the synchronous pulleys and the synchronous belt, which would cause the pulley component 12 to malfunction or even damage the entire moving component.

[0033] A slide rail 13 is provided on the outer side of the threaded rod. The slide rail 13 is concave in shape, and the threaded rod is rotatably connected to the inner side of the concave slide rail 13. A limit plate is provided above the slide rail 13 and is fixedly connected to the slide rail 13. A slide groove is provided below the slider 14, and the limit plate is located in the slide groove. A threaded hole is provided at the bottom of the slider 14, which engages with the threaded rod. As the motor rotates in both directions, it drives the slider 14 to move back and forth on the slide rail 13. At the same time, during the testing of the vehicle USB interface, it is necessary to precisely control the position of the docking component to ensure that the test probe can be accurately inserted into the interface under test. The presence of the limit plate makes the movement of the slider 14 more stable, reduces the test error caused by shaking or offset, and thus improves the accuracy and reliability of the test.

[0034] The main body of the connecting plate 15 and the insert plate 16 are circuit components used for detection and connection. They are equipped with plastic protective shells on their outer sides, and these shells are fixedly connected to the slider 14. The insert plate 16 is horizontally connected to the top of the slider 14, and the insertion hole is also located directly above the insert plate 16, allowing the vision inspection module to detect the insertion hole. The connecting plate 15 is vertically fixed above the slider 14, and in cross-section, the connecting plate 15 has three vertical sides surrounding the insert plate 16, forming an inner and outer side. The inner side is the side closest to the insert plate 16, and the outer side is the side opposite to the inner side. A connecting wire extends from the bottom of the plug board 16 and connects to the inside of the connecting board 15. The connecting wire is an electrical wire. Both the connecting board 15 and the plug board 16 are circuit components with circuit boards as the main body. The plug board 16 has two types of sockets: one is the old-fashioned USB port A, and the other is the commonly used USB port Type-C. Both types of sockets are connected to the circuit board of the plug board 16 and connected to the connecting board 15 through the connecting wire. Several probes are set on the outside of the connecting board 15. The test probes are used to dock with the docking module to test the vehicle USB interface. During the test, the components are moved to load and unload the components.

[0035] The gripping mechanism 3 includes a rotating component and a gripper 34 disposed at the bottom of the rotating component; the gripper 34 is used to grip the docking module.

[0036] In this utility model, the rotating assembly includes a base 30, a first rotating part 31 disposed on the base 30, and a second rotating part 32 connected to the first rotating part 31; a cylinder 33 is disposed in the vertical direction of the second rotating part 32; a gripper 34 is fixedly connected to the bottom of the cylinder 33 and is used to grip the plug.

[0037] It should be noted that the first rotating part 31 and the second rotating part 32 have the same structure, including a rotating motor and a rotating component. The rotating motor is a servo motor, which is located inside the rotating component. The rotating motor controls the rotating component to rotate at any angle. The base 30 is fixedly connected to the base 4. The rotating component of the first rotating part 31 is slidably connected to the base 30. The rotating motor body is fixed inside the rotating component, and the rotating shaft of the rotating motor is fixedly connected to the base 30. As the rotating motor rotates, it drives the rotating component of the first rotating part 31 to rotate. The second rotating part 32 has the same structure as the first rotating part 31. The rotating motor body of the second rotating part 32 is fixedly connected to the rotating component of the second rotating part 32, and its rotating shaft is fixedly connected to the rotating component of the first part. The cylinder 33 is fixedly connected to the end of the second rotating part 32 opposite to the rotating motor. Thus, as the two rotating motors rotate, the cylinder 33 is driven to move to any position above the base 4. The gripper 34 is fixedly connected to the bottom of the cylinder 33. The gripper 34 moves up and down with the extension and retraction of the cylinder 33.

[0038] During testing, the operator inserts the plug into any corresponding hole on the plug plate 16 according to the style of the vehicle USB interface. Then, the visual inspection module 22 on the inner top of the base 4 performs visual inspection to find the plug with the style of the other empty hole. Then, the rotating component rotates, driving the gripper 34 to move to the plug of the docking box 20. The gripper 34 picks up the plug with the style of the empty hole. Then, the cylinder 33 retracts, and at the same time, the first rotating part 31 and the second rotating part 32 extend to pull the plug out and move it to the operator. The operator removes the plug and inserts it into the empty hole. Finally, the moving component moves the plug plate 16 with the plug and vehicle USB interface, so that the probe on the connecting plate 15 is inserted into the docking box 20, and the product to be tested is connected to the inspection module 22 through the docking box 20.

[0039] The testing mechanism 2 includes: a testing module 22, and a docking module connected to the testing module 22; the testing module 22 is used to test whether the vehicle USB interface is connected; the docking module is provided with several docking parts, which can dock with the docking components.

[0040] In a preferred embodiment of the present invention, the docking module includes a docking box 20, a shrinkable member disposed within the docking box 20, and several different plugs disposed on the shrinkable member. The plugs are capable of communicating with the sockets on the plug plate 16. The bottom of the docking box 20 is connected to the detection module 22.

[0041] It should be noted that the detection module 22 is located at the bottom of the base 4. The detection module 22 contains a signal processing unit, a control unit, and a docking unit. The signal processing unit is responsible for receiving signals from the docking module and processing and analyzing these signals, including but not limited to amplifiers, filters, analog-to-digital converters, and other circuits, to ensure the accuracy and reliability of the signals. The control unit is responsible for coordinating the work of each component and making decisions based on the processed signals. The interface circuit is connected to the docking module and is used to transmit detection signals and control signals.

[0042] At the bottom of the docking box 20, at the same level as the probe of the connecting plate 15, the docking box 20 is provided with a probe interface. As the connecting plate 15 moves to the end of the slide rail 13, the probe on the connecting plate 15 is inserted into the probe interface of the docking box 20. The retraction component is mainly composed of a spiral spring. Several plugs of different styles are wound around the outside of the spiral spring. When the gripper 34 clamps and pulls the plug, the spiral spring is stretched. When the gripper 34 is released, the spiral spring retracts, driving the plug to retract. A circuit board is also provided inside the docking box 20. The plugs are all connected to the fixed Luban. At the same time, the probe interface is also connected to the circuit board. The bottom of the circuit board is connected to the detection module 22. Thus, when the probe is inserted into the probe interface, the vehicle USB interface, the plug plate 16, the connecting plate 15, the docking box 20 and the detection module 22 form a closed loop to detect the vehicle USB interface.

[0043] During the inspection process, the operator inserts the plug into any corresponding hole on the connector plate 16 according to the style of the vehicle's USB interface. Then, visual inspection is performed by the vision inspection module 22 on the top inner side of the base 4 to find the plug of the corresponding empty hole style. Then, the rotating component rotates, driving the gripper 34 to move to the plug of the docking box 20. The gripper 34 picks up the plug of the empty hole style. Then, the cylinder 33 retracts, and at the same time, the first rotating part 31 and the second rotating part 32 extend to pull out the plug and move it to the operator. The operator removes the plug and inserts it into the empty hole. Then, the connecting plate 15 moves to the designated position, which is the docking box 20. This allows the connecting plate 15 to connect with the docking box 20. After the plug and socket are connected, the detection module 22 establishes an electrical connection with the circuit components on the plug-in plate 16 through the interface circuit. The detection module 22 sends detection signals to the plug-in plate 16 through the interface circuit. These signals include, but are not limited to, voltage, current, or specific data patterns. After receiving the signals, the circuit components on the plug-in plate 16 process them accordingly and transmit the processed signals back to the detection module 22. The signal processing unit in the detection module 22 amplifies and filters the received signals to improve their accuracy and reliability. The processed signals are then sent to the control unit for further analysis. The control unit determines whether the USB interface is connected based on a preset threshold or algorithm and outputs the result. If the USB interface has good connectivity, the detection module 22 will output a normal signal or a green light indicator. If the USB interface is faulty or has poor connectivity, the detection module 22 will output an abnormal signal or a red light indicator.

[0044] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
