[0035] This embodiment discloses a ZIF connector test fixture for testing a product under test (DUT) with a ZIF connector 500 mounted on it. The ZIF connector 500 is provided with a pressure cap 510. Please refer to... Figures 1 to 4The ZIF connector test fixture includes a base 100, a worktable 200, an upper needle module 300, and a lower needle module 400. The worktable 200 is mounted on the base 100 and includes an air blowing assembly 210, a laser sensor group 220, and a slide rail 230. The air blowing assembly 210 faces the pressure cap 510. The laser sensor group 220 is mounted on both sides of the slide rail 230 to detect whether the pressure cap 510 is blown over by the air blowing assembly 210. The upper needle module 300 includes a bracket 310, a needle die pressure plate 320, and a drive component 330. The bracket 310 is fixed to the worktable 200 and located above the slide rail 230. The drive component 330 is mounted on the bracket 310, and the needle die pressure plate 320 is connected to the moving end of the drive component 330. The needle module 400 includes a support plate 410 and a product carrier plate 420. The support plate 410 is mounted on the slide rail 230, and the product carrier plate 420 is placed on the support plate 410. The product carrier plate 420 is provided with a plurality of grooves 421 for placing the product to be tested.
[0036] The workbench 200 is equipped with an air blowing assembly 210, a laser sensor group 220, and a slide rail 230. During testing, the air blowing assembly 210 blows down the cover 510 of the ZIF connector 500, and the laser sensor group 220 detects the opening angle of the cover 510. A bracket 310 is fixed to the workbench 200, providing support for the upper pin module 300. The pin mold pressure plate 320, driven by a drive component 330, achieves precise pressing of the product under test, thereby accurately testing the electrical performance of the ZIF connector. A support plate 410 is mounted on the slide rail 230, ensuring that the product carrier plate 420 moves along a predetermined path on the workbench 200. A groove 421 on the product carrier plate 420 is used to place the product under test, thus enabling pin-down testing of the ZIF connector 500 mounted on the product under test. The worktable 200 is equipped with loading / unloading positions and a testing position. The slide rail 230 moves the product carrier plate 420 from the loading / unloading positions to the testing position, aligning the upper pin module 300 and the lower pin module 400. The driving component 330 presses down the pin die plate 320 to contact the product to be tested on the product carrier plate 420. The air blowing assembly 210 and the laser sensor group 220 ensure that the pressure cover 510 is blown down, thereby enabling pin testing of the ZIF connector, ensuring testing accuracy and improving testing efficiency.
[0037] Please see Figure 4The air blowing assembly 210 includes an air source regulating valve 211 and an air blowing port 212. The air source regulating valve 211 is connected to an external air source and communicates with the air blowing port 212. The air source regulating valve 211 regulates the flow rate and pressure of the gas from the external air source to ensure that the amount and pressure of gas supplied to the air blowing port 212 are appropriate to meet the actual use requirements. The air blowing port 212 faces the cover 510 of the ZIF connector 500 and blows out the gas regulated by the air source regulating valve 211 at a certain speed and direction, which can blow down the cover 510 to facilitate the pin insertion test of the ZIF connector.
[0038] Please see Figure 4 The laser sensor group 220 includes a first laser sensor 221 and a second laser sensor 222, which are respectively mounted on both sides of the slide rail 230. The laser sensor group 220 is a through-beam sensor; for example, the first laser sensor 221 is a laser emitter, and the second laser sensor 222 is a laser receiver. When the cover 510 is blown over, it does not block the light emitted by the first laser sensor 221. When the optical path is not interrupted, the second laser sensor 222 analyzes the signal and triggers a switch state change, thereby detecting that the cover 510 has been blown over. The driving component 330 then drives the needle die plate 320 to press down.
[0039] Please see Figure 3 and Figure 6 The bottom of the pin mold plate 320 is equipped with an upper probe 321, a connector pin mold 322, and an upper pressure block 323. The upper probe 321 abuts against the TYPE-C interface of the product under test. The ZIF connector 500 is equipped with a ZIF mating seat 520, and the connector pin mold 322 abuts against the ZIF mating seat 520. The upper pressure block 323 is used to press the product under test. The upper probe 321 is used to contact and detect the TYPE-C interface of the product under test to ensure accurate alignment of the interface. The connector pin mold 322 is responsible for mating with the ZIF mating seat 520 to perform pin insertion testing. The function of the upper pressure block 323 is to fix and press the product under test, ensuring stability during the testing process and ensuring that all connection points maintain good electrical contact during the test, achieving accurate test results.
[0040] Please see Figure 5 The product carrier plate 420 is equipped with a lower probe 422 and a limiting block 423. The lower probe 422 abuts against the product under test, and the limiting block 423 is used to limit the position of the product under test. The function of the lower probe 422 is to contact the product under test to ensure that the position of the product under test is fixed during the test; the limiting block 423 is used to limit the position of the product under test after it is placed on the product carrier plate to prevent it from moving or shifting during the test, ensuring that the product under test remains stable throughout the test and avoiding inaccurate testing or damage due to position changes.
[0041] Please see Figure 2 The driving component 330 includes a first cylinder 331 and a second cylinder 332, which are respectively connected to both ends of the needle die plate 320. This ensures that when the driving component 330 drives the needle die plate 320 to press down, both ends of the needle die plate 320 remain horizontal, the pressing force is even, and the connection point between the needle die plate 320 and the product under test maintains good electrical contact.
[0042] Please see Figure 5 The support plate 410 is equipped with multiple limiting posts 411, which are used to limit the movement of the product carrier plate 420. The function of the support plate 410 is to provide a stable support platform for the product carrier plate 420, ensuring that it is not easily displaced during movement or testing. By precisely limiting the edges of the product carrier plate 420 with multiple limiting posts 411, the product carrier plate 420 is prevented from slipping on the support plate 410, avoiding displacement caused by slight vibrations or external forces, thereby ensuring stability during the testing process.
[0043] Please see Figure 3 and Figure 5 The needle mold platen 320 is provided with one of a guide pin 324 and a guide hole 424; the product carrier plate 420 is provided with the other of the guide pin 324 and guide hole 424, the size of the guide pin 324 being adapted to the size of the guide hole 424. The guide pin 324 and guide hole 424 are used in pairs; for example, the needle mold platen 320 ensures precise alignment with the product carrier plate 420 during the pressing process through its provided guide pin 324. The guide pin 324 of the needle mold platen 320 and the guide hole 424 provided on the product carrier plate 420 precisely cooperate to achieve positioning and guiding functions, ensuring that the two always maintain the correct alignment relationship during relative movement. Through this precise cooperation, not only can accurate positioning be achieved, but the guide pin 324 can also further restrict the movement direction of the needle mold platen 320, ensuring stability during the testing process.
[0044] This embodiment also discloses an automated testing device, including the ZIF connector test fixture described above.
[0045] During testing, multiple products to be tested are placed in the grooves 421 of the product carrier plate 420, and then the slide rail 230 moves the product carrier plate 420 to the testing position. The air blowing assembly 210 blows compressed air through the air blowing port 212, blowing down the pressure cover 510. When the laser sensor group 220 detects that the opening angle of the pressure cover 510 is less than 90°, the drive component 330 drives the needle die plate 320 to press down, the upper probe 321 abuts against the TYPE-C interface of the product to be tested, the connector needle die 322 abuts against the ZIF docking seat 520, and the upper pressure block 323 presses down on the product to be tested, and the test begins. After the test is completed, the drive component 330 drives the needle die plate 320 to move upward to detach from the tested product; the slide rail 230 moves the product carrier plate 420 to the loading / unloading position for easy removal of the tested product. By using compressed air to blow down the cover 510 and detecting that the angle of the cover 510 is less than 90°, the ZIF connector pin test is automatically started, improving testing efficiency and meeting the requirements of automated testing on the production line.
[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
