[0017] Beneficial effects

[0018] The present invention has the following beneficial effects:

[0019] (1) The connector airtightness testing fixture is conveyed to the top of the feeding inclined plate by the feeding conveyor belt. Since the feeding inclined plate is a sloping structure, the connector to be tested falls into the limiting cavity through the feeding inclined plate. At this time, the connector to be tested is in contact with the surface of the carrier plate. The carrier plate moves down along the limiting cavity, the connecting spring is squeezed, and at the same time, the connector to be tested is in contact with the pressure sensor. The pressure sensor detects the pressure change and transmits the detection signal to the controller. The controller controls the electric telescopic rod to extend. At this time, the connector to be tested is fixed in the limiting cavity by the side clamp.

[0020] (2) The connector airtightness test fixture uses a controller to control a hydraulic pump to drive the drive shaft to move downward, thereby causing the upper test plate to contact the lower test plate, thus performing an airtightness test on the connector in the limiting cavity. The test result is sent to the controller. After the test is completed, the controller controls the electric telescopic rod to shorten again, and at the same time connects the electromagnet to the circuit. The carrier plate is made of magnetic material. Since the electromagnet and the corresponding surface of the carrier plate have the same magnetism, under the action of magnetic repulsion, the carrier plate moves upward along the limiting cavity, thereby pushing the tested connector out of the limiting cavity.

[0021] (3) When the connector airtightness test fixture passes the test, the controller controls the rotating motor to drive the rotating shaft to rotate, thereby driving the material feeding shaft to rotate, and the connector that has passed the test is moved from the support plate to the discharge inclined plate, and then falls into the collection trough for easy collection. If the test fails, the controller controls the prompt device to issue a prompt, and the staff manually removes the connector that has failed the test to avoid errors.

[0022] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] Furthermore, the testing assembly includes an upper test plate 7 and a guide shaft 8. A drive shaft 6 is mounted on the bottom surface of the output end of the hydraulic pump 5. The bottom surface of the drive shaft 6 extends to the bottom of the testing bracket 2. The upper test plate 7 is mounted on the bottom surface of the drive shaft 6, and the guide shaft 8 is mounted on the top surface of the upper test plate 7. A through groove 9 is provided inside the testing bracket 2. The outer surface of the guide shaft 8 is movably mounted on the inner wall of the through groove 9. The controller 3 controls the hydraulic pump 5 to drive the drive shaft 6 to move downward, thereby causing the upper test plate 7 to contact the lower test plate 10, thereby performing an airtightness test on the connector in the limiting cavity 11. The test result is sent to the controller.

[0034] Furthermore, the limiting fixture includes a fixture assembly and a limiting assembly. The fixture assembly is installed on the top surface of the fixture base 1, and the limiting assembly is installed inside the fixture assembly. The fixture assembly includes a lower test plate 10 and a support plate 13. The lower test plate 10 is installed on the top surface of the fixture base 1, and a limiting cavity 11 is formed inside the lower test plate 10. A connecting spring 12 is installed at the bottom end of the inner wall of the limiting cavity 11. The support plate 13 is installed on the top surface of the connecting spring 12. An electromagnet 14 is installed inside the lower test plate 10 below the limiting cavity 11. A pressure sensor 15 is installed on the top surface of the support plate 13. The pressure sensor 15 is electrically connected to the controller 3, and the controller 3 is electrically connected to the electromagnet 14. The connector to be tested contacts the surface of the support plate 13. The support plate 13 moves downward along the limiting cavity 11, the connecting spring 12 is squeezed, and at the same time, the connector to be tested contacts the pressure sensor 15.

[0035] Furthermore, the limiting assembly includes a side clamping plate 17 and an electric telescopic rod 16. The electric telescopic rod 16 is installed on the inner wall of the limiting cavity 11, and the side clamping plate 17 is installed on the outer surface of the output end of the electric telescopic rod 16. The material guiding mechanism includes a feeding assembly and a material guiding assembly. The feeding assembly is installed on one side surface of the lower test plate 10, and the material guiding assembly is installed on the other side surface of the lower test plate 10. The pressure sensor 15 detects the pressure change and transmits the detection signal to the controller 3. The controller 3 controls the electric telescopic rod 16 to extend. At this time, the connector to be tested is fixed in the limiting cavity 11 by the side clamping plate 17.

[0036] Furthermore, the feeding assembly includes a feeding conveyor belt 18 and a feeding ramp 19. The feeding conveyor belt 18 is mounted on the top surface of the clamp base 1 on one side of the lower test plate 10, and the feeding ramp 19 is mounted on a fixed surface of the lower test plate 10. The end of the feeding conveyor belt 18 extends to the top of the feeding ramp 19. The connectors to be tested are placed sequentially on the feeding conveyor belt 18 by the dropping mechanism and conveyed to the top of the feeding ramp 19 by the feeding conveyor belt 18. Since the feeding ramp 19 has an inclined structure, the connectors to be tested fall into the limiting cavity 11 through the feeding ramp 19.

[0037] Furthermore, the material guiding assembly includes a rotating motor 20 and a material collection trough 24. The rotating motor 20 is installed on the top surface of the lower test plate 10. A rotating shaft 21 is installed on the top surface of the output end of the rotating motor 20. A material-pushing shaft 22 is installed on the outer surface of the rotating shaft 21. A discharge ramp 23 is installed on one side surface of the lower test plate 10. The material collection trough 24 is installed on one side surface of the fixture base 1. The controller 3 controls the rotating motor 20 to drive the rotating shaft 21 to rotate, thereby driving the material-pushing shaft 22 to rotate. The connectors that pass the test are pushed from the support plate 13 to the discharge ramp 23 and then fall into the material collection trough 24 for easy collection. If the test fails, the controller 3 controls the prompt device 4 to issue a prompt. The operator manually removes the connectors that fail the test to avoid errors.

[0038] During use (operation), the connectors to be tested are placed sequentially on the feeding conveyor belt 18 via the feeding mechanism. The feeding conveyor belt 18 transports the connectors to the top of the feeding inclined plate 19. Since the feeding inclined plate 19 is a sloping structure, the connectors to be tested fall into the limiting cavity 11 through the feeding inclined plate 19. At this time, the connectors to be tested are in contact with the surface of the support plate 13. The support plate 13 moves downward along the limiting cavity 11, and the connecting spring 12 is squeezed. At the same time, the connectors to be tested are in contact with the pressure sensor 15. The pressure sensor 15 detects the pressure change and transmits the detection signal to the controller 3. The controller 3 controls the electric telescopic rod 16 to extend. At this time, the connectors to be tested are fixed in the limiting cavity 11 by the side clamp 17.

[0039] The controller 3 controls the hydraulic pump 5 to drive the drive shaft 6 to move downward, thereby causing the upper test plate 7 to contact the lower test plate 10, thus performing an airtightness test on the connector in the limiting cavity 11. The test result is sent to the controller 3. After the test is completed, the controller 3 controls the electric telescopic rod 16 to shorten again, and at the same time connects the electromagnet 14 to the circuit. The carrier plate 13 is made of magnetic material. Since the electromagnet 14 and the corresponding surface of the carrier plate 13 have the same magnetism, under the action of magnetic repulsion, the carrier plate 13 moves upward along the limiting cavity 11, thereby pushing the tested connector out of the limiting cavity 11.

[0040] When the test is passed, the controller 3 controls the rotating motor 20 to drive the rotating shaft 21 to rotate, which in turn drives the feeding shaft 22 to rotate, moving the connector that passed the test from the support plate 13 to the discharge inclined plate 23, and then falling into the collection trough 24 for easy collection. If the test fails, the controller 3 controls the prompt device 4 to issue a prompt, and the staff manually removes the connector that failed the test to avoid errors.
