If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.

[0029] One embodiment of the present application provides a testing device, comprising a testing apparatus capable of performing a sealing test on a workpiece. Furthermore, the workpiece may be a pneumatic plug connector having a self-locking function, and the testing apparatus can automatically unlock the workpiece to facilitate assembly and disassembly for testing.

[0030] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides an exemplary structure of a workpiece 20. The workpiece 20 includes an outer sleeve 21, an inner sleeve 22, a limiting ball 23 and a spring 24. The outer sleeve 21 is sleeved on the outer periphery of the inner sleeve 22. The spring 24 is located between the inner sleeve 22 and the outer sleeve 21 and elastically connects the inner sleeve 22 and the outer sleeve 21. A limiting hole 25 is provided through the peripheral wall of the inner sleeve 22, and the limiting ball 23 is movably provided in the inner sleeve 22. A push block 26 and a receiving groove 27 are provided on the inner periphery of the outer sleeve 21. Figure 1 The workpiece 20 is in a self-locking state. At this time, the push block 26 of the outer sleeve 21 pushes the limiting ball 23 radially inward, causing the limiting ball 23 to protrude inward to engage the plug inserted into the workpiece 20. Driving the outer sleeve 21 to slide axially can unlock the workpiece 20. Figure 2 When the outer sleeve 21 slides to a position where the receiving groove 27 and the limiting ball 23 are radially aligned, the limiting ball 23 can move radially outward to enter the receiving groove 27. At this time, the limiting ball 23 no longer engages the plug, thereby unlocking the workpiece 20. It should be emphasized that the workpiece 20 provided in this embodiment is only one type of workpiece 20 that can be tested by the test device 11. The test equipment and test device 11 provided in each embodiment of the present application can also test other workpieces 20 with self-locking functions.

[0031] See also Figure 3 and Figure 4 In one embodiment, the testing equipment further includes a conveying device 12 and a jig 13. The jig 13 is used to support the workpiece 20. The jig 13 is provided on the conveying device 12. The conveying device 12 can drive the jig 13 to move to switch the jig 13 located at the testing device 11, so that the testing device 11 can continuously test the workpiece 20 supported by different jigs 13.

[0032] Please refer again Figure 3One embodiment of the present application provides a testing device 11, which includes a fixing frame 100, a carrier frame 200, a test connector 300 and an unlocking frame 400. The carrier frame 200 is movably provided on the fixing frame 100 to move between a first position and a second position along a reference direction S. The test connector 300 is provided on the carrier frame 200, and the test connector 300 is used to transport a test medium. The unlocking frame 400 is movably provided on the carrier frame 200. When the carrier frame 200 is in the first position, the test connector 300 is used to connect with the workpiece 20 to provide the test medium to the workpiece 20. Moreover, when the carrier frame 200 is in the first position, the unlocking frame 400 is used to connect with the workpiece 20 to drive the workpiece 20 to unlock. When the carrier frame 200 is in the second position, the test connector 300 and the unlocking frame 400 are used to separate from the workpiece 20.

[0033] In the aforementioned testing device 11, the test connector 300 is mounted on the carrier 200. The carrier 200 can move the test connector 300 to a position where it connects with the workpiece 20 for testing. Furthermore, the carrier 200 is provided with a movable unlocking frame 400. When the test connector 300 is connected to the workpiece 20, the unlocking frame 400 can also connect to the workpiece 20. Therefore, after testing is complete, the workpiece 20 can be unlocked from the test connector 300 by driving the unlocking frame 400 relative to the carrier 200.

[0034] For example, with the exemplary workpiece 20 provided above, when the test connector 300 is connected to the workpiece 20, the unlocking frame 400 can be connected to the outer sleeve 21. Thus, when the test is completed, the unlocking frame 400 moves relative to the carrier 200, driving the outer sleeve 21 to move axially to a position where the receiving groove 27 aligns with the stop ball 23, thereby unlocking the workpiece 20. The unlocking frame 400 can move relative to the carrier 200 along the reference direction S.

[0035] In one embodiment, the testing equipment may further include a test medium generator (not shown, the same applies below). The test medium generator is connected to the test connector 300 to supply the test medium to the test connector 300. When the test connector 300 is connected to the workpiece 20, the test medium is supplied to the workpiece 20. If the seal of the workpiece 20 is poor, the test medium may leak. Furthermore, the fixture 13 is used to seal the end of the workpiece 20 away from the test connector 300. The fixture 13, in conjunction with the test connector 300, provides the workpiece 20 with an environmental foundation for a seal test. For example, when the testing device 11 performs an airtightness test on the workpiece 20, the test medium is configured as positive or negative pressure gas. If the test connector 300 supplies positive or negative pressure gas to the workpiece 20 and gas leaks from the workpiece 20, the seal may be insufficient. Furthermore, the test medium generator can obtain the pressure conditions within the workpiece 20 through the test connector 300 to determine the airtightness of the workpiece 20. Of course, when the testing device 11 performs other sealing tests on the workpiece 20 , the testing medium may be configured as other substances, which will not be described in detail here.

[0036] See also Figure 5 and Figure 6 In one embodiment, there are multiple test connectors 300 arranged in an array on the carrier 200. Accordingly, the fixture 13 can support multiple workpieces 20, and the relative positions of the multiple test connectors 300 match the relative positions of the multiple workpieces 20 on the fixture 13. Therefore, when the carrier 200 moves along the reference direction S to the first position, the multiple test connectors 300 can be connected to the multiple workpieces 20.

[0037] Furthermore, the carrier 200 may be provided with a test area 211 , and the test connector 300 is provided in the test area 211 of the carrier 200 .

[0038] Please refer again Figure 4 In one embodiment, the testing device 11 includes a first driver 600 and a second driver 700. The first driver 600 is provided on the carrier 200 and is used to drive the unlocking frame 400 to move along the reference direction S to unlock the workpiece 20. The second driver 700 is provided on the fixed frame 100 and connected to the carrier 200 to drive the carrier 200 to move along the reference direction S.

[0039] Please continue reading Figure 5 and Figure 6In one embodiment, the unlocking frame 400 includes an unlocking plate 410. The carrier frame 200 includes a carrier plate 210. The unlocking plate 410 is disposed on a side of the carrier plate 210 proximate to the workpiece 20. The unlocking plate 410 is movable relative to the carrier plate 210 to unlock the workpiece 20. The unlocking plate 410 defines a connecting hole 411. The test connector 300 is disposed on the carrier plate 210 and passes through the connecting hole 411 for connection with the workpiece 20. Positioning the unlocking plate 410 on the side of the carrier plate 210 proximate to the workpiece 20 facilitates movement of the unlocking plate 410 to unlock the workpiece 20. In this embodiment, the first driver 600 may be disposed on the carrier plate 210. The output shaft of the first driver 600 may pass through the carrier plate 210 and connect to the unlocking plate 410, thereby driving the unlocking plate 410 to move. In this embodiment, the unlocking plate 410 can engage with the outer cover 21 through the connecting hole 411 of the unlocking plate 410, thereby driving the outer cover 21 to unlock. For example, a stopper may be provided on the wall of the communication hole 411, which engages with the outer sleeve 21 (e.g., by snapping or tightly gripping) to drive the outer sleeve 21 to unlock. Of course, the unlocking plate 410 can be positioned elsewhere and used to unlock the workpiece 20. For example, if the workpiece 20 requires rotational unlocking, the first actuator 600 can be configured to rotate the unlocking plate 410 to unlock the workpiece 20. The unlocking method of the unlocking plate 410 can be designed to adapt to the unlocking method of the workpiece 20 and will not be further described here.

[0040] In one embodiment, the test area 211 may be located on the carrier 210 , and the test connector 300 is disposed in the test area 211 of the carrier 210 .

[0041] It is understandable that if Figure 5 、 Figure 6As shown, the first actuator 600 can also be located elsewhere on the carrier 200. For example, in one embodiment, the carrier 200 includes a connecting frame 220 and a first rod 230. The unlocking frame 400 also includes a push plate 420 and a second rod 430. Along a reference direction S, the connecting frame 220, the push plate 420, the carrier 210, and the unlocking plate 410 are sequentially arranged. The second rod 430 passes through the carrier 210 and is connected between the unlocking plate 410 and the push plate 420, enabling synchronized movement of the unlocking plates 410 and the push plate 420 on either side of the carrier 210. The first rod 230 passes through the push plate 420 and is connected between the connecting frame 220 and the carrier 210, enabling synchronized movement of the connecting frame 220 and the carrier 210 on either side of the push plate 420. The first actuator 600 is located on the connecting frame 220 and is connected to the push plate 420 to drive the unlocking frame 400 to move along the reference direction S. With this arrangement, the first actuator 600 does not need to be located on the carrier plate 210. Instead, the first actuator 600 can drive the unlocking plate 410 by moving the push plate 420. This reduces the space occupied on the carrier plate 210, facilitating the placement of the test connector 300. Furthermore, the test connector 300 is connected to the test medium generator via a delivery element such as a pipe, thus reducing the space occupied on the carrier plate 210 and facilitating the placement of delivery elements.

[0042] Furthermore, the plurality of first rods 230 and the plurality of second rods 430 are located outside the test area 211, so that the plurality of test connectors 300 in the test area 211 can be arranged to align with the plurality of workpieces 20 on the fixture 13. For example, the test connectors 300 in the test area 211 can be arranged in a rectangular array.

[0043] It should be understood that in the reference direction S, there is sufficient space between the unlocking plate 410 and the push plate 420 connected by the second rod 430, and there is sufficient space between the connecting frame 220 and the carrier plate 210 connected by the first rod 230, so that the unlocking frame 400 has sufficient space for movement.

[0044] Please refer again Figure 3 In one embodiment, the second driver 700 is connected to the connecting frame 220 to drive the supporting frame 200 and the unlocking frame 400 provided on the supporting frame 200 to move along the reference direction S.

[0045] Furthermore, the fixing frame 100 includes a top plate 110 and two vertical plates 120 connected to the ends of the top plate 110. The supporting frame 200 and the unlocking frame 400 disposed on the supporting frame 200 are located between the two vertical plates 120. The second actuator 700 is disposed on the top plate 110 and connected to the connecting frame 220. The vertical plates 120 are provided with guide rails 121 extending along the reference direction S, and the supporting frame 200 is slidably engaged with the guide rails 121.

[0046] Please refer again Figure 3 In one embodiment, the testing device 11 further includes a stopper assembly 500 disposed on the fixed frame 100. The stopper assembly 500 includes a first stopper (not shown, similarly hereinafter) and a second stopper 510. Along the reference direction S, the first and second stoppers 510 are respectively disposed on either side of the carrier 200. When pressed by the carrier 200, the first and second stoppers 510 stop the carrier 200 from moving. Thus, the cooperation between the first and second stoppers 510 keeps the carrier 200 within a predetermined range, preventing damage to the workpiece 20.

[0047] Furthermore, the fixing frame 100 further includes a mounting plate 130 , which is disposed on the vertical plate 120 . The first stopper is disposed on the top plate 110 , and the second stopper 510 is disposed on the mounting plate 130 .

[0048] See also Figures 3 to 5 In one embodiment, the first stopper can be configured to be movably provided on the fixing frame 100 along the reference direction S, that is, the first stopper can be movably provided on the vertical plate 120. The stopper assembly 500 further includes a third driver 520, which is connected to the first stopper to drive the first stopper to move along the reference direction S. Furthermore, the first stopper can be provided at the end of the output shaft of the third driver 520, so that the third driver 520 can conveniently drive the first stopper to move.

[0049] When the carrier 200 is in the second position, the first stopper extends to a position at a first preset distance from the top surface of the carrier 200. The carrier 200 moves the first preset distance toward the first position, establishing a second preset distance between the carrier 200 and the jig 13 supporting the workpiece 20. By configuring the first stopper to extend, the carrier 200 can be positioned in a third position, where the carrier 200 is at the second preset distance from the jig 13. It should be understood that the third position is between the first and second positions, being closer to the first position than the second position. Configuring the carrier 200 in the third position, firstly, provides space for the unlocking movement of the unlocking plate 410. Secondly, when the testing device 11 performs a negative pressure airtightness test on the workpiece 20, even if the gap between the workpiece 20 and the test connector 300 is unlocked, the workpiece 20 can still be held to the test connector 300 by the negative pressure. In this embodiment, the carrier 200 is configured to have a third position. When in the third position, the carrier 200 is elevated by a first predetermined distance relative to the carrier 200 in the second position. This reduces the blocking effect of the fixture 13 on the workpiece 20, thereby reducing the negative pressure adsorption effect and facilitating separation of the workpiece 20 from the test connector 300. Simultaneously, movement of the unlocking plate 410 in the reference direction S can also press the workpiece 20 back into the fixture 13. In short, this configuration in this embodiment facilitates separation of the test connector 300 from the workpiece 20.

[0050] The specific values ​​of the first preset distance and the second preset distance can be designed according to actual needs and are not limited in this application.

[0051] See also Figure 7 In one embodiment, the testing apparatus further includes a testing device 14. The conveying device 12 is capable of moving the jig 13 to the testing device 14. The testing device 14 is used to drive the outer sleeve 21 and inner sleeve 22 of the workpiece 20 to move relative to each other, thereby compressing the spring 24 connected between the outer sleeve 21 and the inner sleeve 22. Thus, the testing device 14 can test the smoothness of movement of the outer sleeve 21 and the inner sleeve 22, as well as the stability of the connection between the spring 24.

[0052] Please continue reading Figure 7 In one embodiment, the test device 14 includes a lifting platform 15 and a picking component 16. The picking component 16 is used to clamp the outer sleeve 21 to pick up the workpiece 20. The lifting platform 15 can lift the inner sleeve 22 of the workpiece 20 clamped by the picking component 16 to drive the inner sleeve 22 to move relative to the outer sleeve 21. Furthermore, the picking component 16 includes a clamping jaw 17 and a driving structure 18. The driving structure 18 is used to drive the clamping jaw 17 to move in at least two intersecting directions to pick up the workpiece 20 from the fixture 13 to a position aligned with the lifting platform 15. A force feedback sensor can be configured in the lifting platform 15 to obtain the feedback force when the lifting platform 15 lifts the inner sleeve 22, so as to obtain the smoothness of the movement of the outer sleeve 21 and the inner sleeve 22 and the stability of the connection between the spring 24.

[0053] In one embodiment, the driving elements such as the first driver 600 , the second driver 700 , the third driver 520 and the driving structure 18 can be driven by components such as cylinders, hydraulics or motors.

[0054] In one embodiment, the conveying device 12 may be configured as a turntable. A plurality of jigs 13 may be provided on the conveying device 12 .
