[0007] In use, the feeding mechanism transports the device under test to the designated position on the mounting platform. The sliding block of the positioning mechanism descends to press the device under test for positioning. The first terminal test connector on the sliding block is connected to the device under test. The wiring robot operates the second terminal test connector to connect to the device under test and perform a pull-in and release voltage test. After the test is completed, the sliding block is reset, and the feeding mechanism transports the device under test to the next station, realizing the automatic completion of the testing process. The testing fixture provided by this utility model solves the problem that existing testing equipment requires manual testing.

The first lifting drive device drives the sliding block to move up and down along the guide rod. A pressure block is disposed at the bottom of the sliding block, and the pressure block is used to press against the device under test (DUT). The first terminal test connector is disposed at the end of the sliding block away from the guide rod. With the above configuration, when the DUT reaches the designated position, the first lifting drive device drives the sliding block to move downward along the guide rod to position the pressure block for the DUT, and the first terminal test connector connects to the DUT. After the test is completed, the first lifting drive device drives the sliding block to move upward along the guide rod to reset the pressure block and the first terminal test connector.

Through this configuration, the cooperation of the first and second horizontal rotating assemblies allows for horizontal adjustment of the position of the second terminal test connector, the telescopic assembly allows for vertical adjustment of the position of the second terminal test connector, and the flipping assembly allows for adjustment of the tilt angle of the second terminal test connector, thereby enabling the second terminal test connector to be smoothly connected to the device under test.

[0011] Optionally, it further includes a displacement testing mechanism, which is movably mounted on the mounting platform and used to test the dynamic and static positions of the drive end of the device under test.

With the above settings, when the device under test (DUT) reaches the designated position, the base plate moves the reference plate and the baffle towards the DUT. The clearance notch on the reference plate avoids the drive end of the DUT, allowing the reference plate to move upward and contact the bottom of the DUT. Using the reference plate as the reference surface for dynamic and static testing, when the DUT is not powered on, the baffle moves upward and contacts the drive end of the DUT to detect the initial position. The baffle moves downward, and when the DUT is powered on, the drive end of the DUT extends, and the baffle moves upward again to contact the drive end of the DUT to detect the working position. The distance between the initial position and the working position is detected by the displacement sensor to complete the dynamic and static position test.

With the above configuration, the supporting platform conveys the device under test along the conveying device to a designated position, and the lifting assembly lifts the supporting platform, detaching it from the conveying device, thus achieving the positioning of the device under test without stopping the conveying device.

[0016] Optionally, the lifting assembly includes: a blocking member, movably mounted on the mounting platform, the blocking member being used to block and cooperate with the support platform; and a top plate, movably mounted on the mounting platform, the top plate having a limiting protrusion, and the bottom of the support platform having a limiting groove for embedding the limiting protrusion. With the above configuration, when the device under test is transported to the designated position, the blocking member and the support platform form a blocking cooperation, preventing the support platform from moving with the conveying device. The top plate moves upward, causing the limiting protrusion to embed into the limiting groove, and lifting the support platform to achieve positioning.

[0034] This embodiment provides a test fixture structure capable of automatic detection, used for voltage testing and dynamic / static position testing of the device under test.

[0035] As shown in Figures 1 and 2, this embodiment provides a specific implementation of a testing fixture, including: an installation platform 1, a feeding mechanism 2, a positioning mechanism 3, and a wiring robot 4; the feeding mechanism 2 is disposed on the installation platform 1 and is used to transport the device under test to a designated position; the positioning mechanism 3 is disposed on the installation platform 1 and is provided with a liftable sliding block 31, which is located above the feeding mechanism 2 and is used to press the device under test, and is also provided with a first terminal test connector 32 for connecting the device under test; the wiring robot 4 is disposed on the installation platform 1 and is provided with a second terminal test connector 41 for connecting the device under test.

[0036] In use, the feeding mechanism 2 transports the device under test to a designated position on the mounting platform 1. The sliding block 31 of the positioning mechanism 3 descends to press the device under test for positioning. The first terminal test connector 32 on the sliding block 31 is connected to the device under test.

After the test is completed, the sliding block 31 is reset, and the feeding mechanism 2 transports the device under test to the next station, realizing the automatic completion of the testing process. The testing fixture provided in this embodiment solves the problem that existing testing equipment requires manual testing.

[0037] It should be noted that the pressure block 35 and the first terminal test connector 32 are provided with elastic buffers to ensure that the pressure block 35 and the first terminal test connector 32 make flexible contact with the device under test, thus avoiding damage.

[0038] As shown in Figures 1-4, in the test fixture provided in this embodiment, the positioning mechanism 3 includes: a guide rod 34, a mounting block 33, and a sliding block 31. The guide rod 34 is disposed on the mounting platform 1. The mounting block 33 is disposed at the top of the guide rod 34, and a first lifting drive device 36 is disposed on the mounting block 33. The sliding block 31 is slidably sleeved on the guide rod 34, and the sliding block 31 is connected to the driving end of the first lifting drive device 36.

A pressure block 35 is disposed at the bottom of the sliding block 31, and the pressure block 35 is used to press against the device under test. The first terminal test connector 32 is disposed at the end of the sliding block 31 away from the guide rod 34. When the device under test (DUT) reaches the designated position, the first lifting drive device 36 drives the sliding block 31 to move downwards along the guide rod 34, so that the pressure block 35 positions the DUT. The first terminal test connector 32 is connected to the DUT. After the test is completed, the first lifting drive device 36 drives the sliding block 31 to move upwards along the guide rod 34, so that the pressure block 35 and the first terminal test connector 32 are reset. Specifically, the first lifting drive device 36 is configured as a servo motor. Alternatively, as an alternative embodiment, the first lifting drive device 36 can also be mounted on the mounting platform 1.

[0039] As shown in Figures 1-4, in the testing fixture provided in this embodiment, a second lifting drive device 37 is provided at the end of the sliding block 31 away from the guide rod 34, and the first terminal test connector 32 is located at the driving end of the second lifting drive device 37. The second lifting drive device 37 can drive the first terminal test connector 32 to move up and down, adjusting the position of the first terminal test connector 32 to adapt to various devices under test. Specifically, the second lifting drive device 37 is configured as an electric slider. Alternatively, as an alternative embodiment, the second lifting drive device 37 can be omitted, and the first terminal test connector 32 is fixedly connected to the sliding block 31.

[0040] As shown in Figures 1, 2, 5, and 6, the wiring robot 4 in the testing fixture provided in this embodiment includes: a bracket 42, disposed on the mounting platform 1; a first horizontal rotation component 43, rotatably disposed on the top of the bracket 42; a second horizontal rotation component 44, rotatably connected to the first horizontal rotation component 43; a telescopic component 45, telescopically disposed on the second horizontal rotation component 44; and a flipping component 46, rotatably disposed on the drive shaft of the telescopic component 45. The second terminal test connector 41 is disposed on the flipping component 46. The cooperation of the first horizontal rotation component 43 and the second horizontal rotation component 44 allows for horizontal adjustment of the position of the second terminal test connector 41. The telescopic component 45 allows for vertical adjustment of the position of the second terminal test connector 41. The flipping component 46 allows for adjustment of the tilt angle of the second terminal test connector 41, thereby enabling the second terminal test connector 41 to be smoothly connected to the device under test. In addition, as an alternative implementation, one or more of the first horizontal rotation component 43, the second horizontal rotation component 44, the telescopic component 45 and the flipping component 46 can be selected and combined arbitrarily according to actual design requirements.

[0041] As shown in Figures 1 and 2, the testing fixture provided in this embodiment further includes a displacement testing mechanism 5, which is movably mounted on the mounting platform 1. The displacement testing mechanism 5 is used to test the dynamic and static positions of the drive end of the device under test. The displacement testing mechanism 5 can automatically test the dynamic and static positions of the drive end of the device under test. Alternatively, as an alternative implementation, the displacement testing mechanism 5 can be omitted, and this testing fixture can then be used only for voltage testing.

[0042] As shown in Figures 1, 2, 7, 8, 9, and 10, the displacement testing mechanism 5 provided in this embodiment includes: a base plate 51, movably mounted on the mounting platform 1; a reference plate 52, vertically mounted on the base plate 51, the reference plate 52 being used to contact the bottom of the device under test, and the reference plate 52 having a clearance notch 521 for avoiding the drive end of the device under test; a baffle 53, vertically mounted on the base plate 51, the baffle 53 being used to contact the bottom of the drive end of the device under test; and a displacement sensor 54, mounted on the reference plate 52, the detection end of the displacement sensor 54 being connected to the baffle 53. When the device under test (DUT) reaches the designated position, the base plate 51 drives the reference plate 52 and the baffle 53 to move towards the DUT. The clearance notch 521 on the reference plate 52 avoids the driving end of the DUT, allowing the reference plate 52 to move upward and contact the bottom of the DUT. Using the reference plate 52 as the reference surface for dynamic and static testing, when the DUT is not powered on, the baffle 53 moves upward and contacts the driving end of the DUT to detect the initial position. The baffle 53 then moves downward. After the DUT is powered on, the driving end of the DUT extends, and the baffle 53 moves upward again to contact the driving end of the DUT to detect the working position. The distance between the initial position and the working position is detected by the displacement sensor 54 to complete the dynamic and static position test. The baffle 53, the reference plate 52, and the base plate 51 then reset. Alternatively, as an alternative implementation, the reference plate 52 can be omitted, and a horizontal moving component is provided on the baffle 53. The baffle 53 first contacts the bottom of the device under test to determine the reference surface, and then descends and is pushed forward by the horizontal moving component so that it can contact the driving end of the device under test.

[0043] As shown in Figures 7-10, in the test fixture provided in this embodiment, a mounting frame 55 is provided below the base plate 51. A third lifting drive device 56 and a fourth lifting drive device 57 are mounted on the mounting frame 55. The driving end of the third lifting drive device 56 is connected to the reference plate 52, and the driving end of the fourth lifting drive device 57 is connected to the baffle 53. The third lifting drive device 56 drives the reference plate 52 to move vertically, so that the reference plate 52 contacts or moves away from the bottom of the device under test. The fourth lifting drive device 57 drives the baffle 53 to move vertically, so that the baffle 53 contacts or moves away from the driving end of the device under test. Alternatively, as an alternative implementation, the mounting frame 55 can be omitted, and the third lifting drive device 56 and the fourth lifting device can be directly mounted on the base plate 51.

[0044] As shown in Figures 2, 7, 8, 9, and 10, in the testing fixture provided in this embodiment, the displacement testing mechanism 5 is equipped with a translation drive device 58. The translation drive device 58 includes a slide rail 581 and a drive block 582. The slide rail 581 is fixedly mounted on the mounting platform 1, and the drive block 582 is fixedly mounted below the base plate 51. The drive block 582 is provided with a groove for embedding into the slide rail 581. The drive block 582 moves horizontally along the slide rail 581, driving the reference plate 52 and the baffle 53 to move towards or away from the device under test via the base plate 51. Specifically, the drive block 582 is configured as an electric slider. Alternatively, as an alternative embodiment, the translation drive device 58 can also be configured as a motor and rack and pinion transmission structure.

[0045] As shown in Figures 1 and 2, in the test fixture provided in this embodiment, the feeding mechanism 2 includes: a conveying device 21, disposed on the mounting platform 1; a supporting platform, movably disposed on the conveying device 21, the supporting platform being used to support and fix the device under test; and a lifting component 22, vertically and vertically disposed on the mounting platform 1, the lifting component 22 being used to position the supporting platform. The supporting platform conveys the device under test along the conveying device 21 to a designated position, and the lifting component 22 lifts the supporting platform, causing the supporting platform to detach from the conveying device 21, thus achieving the positioning of the device under test without stopping the conveying device 21. Alternatively, as an alternative implementation, the lifting component 22 can be omitted, and after the conveying device 21 conveys the supporting platform to the designated position, the conveying device 21 stops operating, allowing the supporting platform to remain at the designated position.

[0046] As shown in Figures 1 and 2, in the test fixture provided in this embodiment, the lifting assembly 22 includes: a blocking member, which is vertically and flexibly disposed on the mounting platform 1, and the blocking member is used to block and cooperate with the carrying platform; and a top plate, which is vertically and flexibly disposed on the mounting platform 1, the top plate being provided with a limiting protrusion, and the bottom of the carrying platform being provided with a limiting groove for embedding the limiting protrusion. When the device under test is transported to the designated position, the blocking member and the carrying platform form a blocking cooperation, so that the carrying platform no longer moves with the conveying device 21, the top plate moves upward, so that the limiting protrusion is embedded in the limiting groove, and the carrying platform is lifted up to achieve positioning of the carrying platform; after the test is completed, the top plate descends, so that the carrying platform is placed on the conveying device 21, the blocking member descends to release the obstruction of the carrying platform, and the conveying device 21 transports the carrying platform and the device under test to the next station. In addition, as an alternative implementation, the top plate can also be provided as multiple push rods, which lift the carrying platform.

[0047] Specifically, the installation platform 1 is equipped with a fifth lifting drive device. The drive end of the fifth lifting drive device is connected to the top plate. The fifth lifting drive device is a servo motor, or it can be a pneumatic push rod or other drive structure that can achieve vertical lifting.

[0048] How to use:

[0049] As shown in Figure 1, the test fixture provided in this embodiment, during use, involves the feeding mechanism 2 conveying the device under test to a designated position on the mounting platform 1, the lifting component 22 lifting and positioning it, the sliding block 31 of the positioning mechanism 3 descending to press the device under test, the first terminal test connector 32 on the sliding block 31 connecting to the device under test, and the wiring robot 4 operating the second terminal test connector 41 to connect to the device under test for a pull-in / release voltage test; the reference plate 52 of the displacement testing mechanism 5 moving forward to below the device under test, and then the reference plate 52 moving upward to press against the bottom of the device under test, with the baffle 53 extending out to meet the bottom of the device under test. After the drive end of the device under test (DUT) makes contact with the device, the baffle 53 shifts downward by 3mm, and the voltage value is gradually increased or decreased at different rates to detect the two extreme values ​​of the voltage. Then, a dynamic and static position test is performed. The test voltage is 8±0.2V. Without power, the baffle 53 is used to fix the drive end of the DUT to detect the initial position. Then, the baffle 53 moves downward. After the DUT is powered on, it moves upward again to fix the drive end of the DUT. The distance between the two positions is detected by the displacement sensor 54. After the test is completed, the reference plate 52, the baffle 53, the sliding block 31, and the wiring robot 4 are reset. The feeding mechanism 2 transports the DUT to the next station to complete the test of a single DUT.

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
