Description

Technical Field

[0001] This utility model relates to the field of product testing, and in particular to an ICT testing fixture for product testing. Background Technology

[0002] A search of Chinese patents revealed publication number CN214622918U, which discloses an ICT testing fixture for automotive parts inspection. The fixture includes a base plate, a frame fixedly connected to the top of the base plate, a hydraulic cylinder fixedly connected to the top of the frame, the output end of the hydraulic cylinder penetrating into the inner cavity of the frame and fixedly connected to a connecting plate, first springs fixedly connected to the four corners of the bottom of the connecting plate, contact mounting plates fixedly connected to the bottom of the first springs, a housing fixedly connected to the top of the base plate, square holes formed at the four corners of the top of the housing, a motor fixedly connected to the front left side of the housing, and a threaded rod fixedly connected to the right end of the motor shaft penetrating into the inner cavity of the housing. This invention solves the problem that existing ICT testing fixtures for automotive parts inspection only place circuit boards without clamping them, allowing the circuit boards to move and affecting the test results, resulting in low reliability.

[0003] Existing test fixtures lack protective features. Test probes are typically exposed, allowing dust to accumulate on their surfaces when not in use, affecting test stability. External objects can also cause collisions, bending and deformation, impacting usability and hindering probe replacement. Generally, a single test probe can only test one circuit board; replacing probes for different boards requires changing them. Since probes are usually secured with multiple bolts, replacement necessitates tools, making the process cumbersome, increasing workload, and reducing efficiency. To address these issues, we propose an ICT test fixture for product testing. Utility Model Content

The other side of the transmission rod 10... A baffle 11 is hinged to the end and slidably connected to the inner wall of the protective shell 6. A drive mechanism 12 is provided on the top of the lead screw 8. The drive mechanism 12 drives the lead screw 8 to rotate. The rotation of the lead screw 8 drives the lifting plate 9 to move. The movement of the lifting plate 9 drives the transmission rod 10 and the test probe 15 to move. The test probe 15 is moved into the interior of the protective shell 6. The movement of the transmission rod 10 causes the baffle 11 to cover the protective shell 6 for protection. This method can achieve the purpose of protection, ensure the cleanliness of the probe, and improve the safety of use.

[0031] refer to Figure 2 The drive mechanism 12 includes a motor 21, which is bolted to the surface of the protective shell 6. The output end of the motor 21 extends into the interior of the protective shell 6 and is connected to a transmission shaft 22 via a coupling. The transmission shaft 22 is rotatably connected to the inner wall of the protective shell 6. A first bevel gear 23 is fixedly sleeved on the surface of the transmission shaft 22. A second bevel gear 24 meshes with the surface of the first bevel gear 23. The axis of the second bevel gear 24 is fixedly sleeved with the top of the lead screw 8. By setting the drive mechanism 12, the lead screw 8 is driven, which is convenient to use.

[0032] refer to Figure 1 A guide rod 25 is bolted to the top of the fixing plate 5, and the guide rod 25 is slidably sleeved with the inner wall of the fixing frame 3. By setting the guide rod 25, the fixing plate 5 is fixed to prevent displacement.

[0033] refer to Figure 1 An alarm light 26 is bolted to the top of the mounting bracket 3. The alarm light 26 facilitates testing.

[0034] Example 2:

[0035] refer to Figure 2 and Figure 3 A mounting base 13 is bolted to the bottom of the lifting plate 9. A mounting rod 14 is slidably sleeved on the inner wall of the mounting base 13. A test probe 15 is bolted to the bottom of the mounting rod 14. A sliding rod 16 is slidably connected to the inner wall of the mounting base 13. A snap-fit ​​connector 17 is bolted to the surface of the sliding rod 16. A snap-fit ​​hole 18 is opened on the surface of the mounting rod 14, and the snap-fit ​​connector 17 snaps into the snap-fit ​​hole 18. A tension spring 19 is fixedly connected between the sliding rod 16 and the inner wall of the mounting base 13 by a spring fastener. A connecting rod 29 is bolted between the sliding rods 16. A pull rod 20 is bolted to the surface of the sliding rod 16. By moving the pull block 27, the pull rod 20 drives the sliding rod 16 to move. The movement of the sliding rod 16 drives the snap-fit ​​connector 17 to move. The movement of the snap-fit ​​connector 17 disengages the snap-fit ​​connector 17 from the snap-fit ​​hole 18, allowing the test probe 15 to be removed and replaced. This method facilitates the replacement of the test probe 15, reduces workload, and improves replacement efficiency.

[0036] refer to Figure 2 and Figure 3 One end of the pull rod 20 is bolted with a pull block 27, which facilitates the movement of the pull rod 20.

[0037] refer to Figure 2 One end of the snap-fit ​​connector 17 is wedge-shaped, which facilitates the installation of the test probe 15.

[0038] refer to Figure 1 The bottom of the base 1 is bolted with a foot 28, which improves the stability of the device.

[0039] Brief description of the usage process: Place the product to be tested in the positioning groove on the test holder 2. The cylinder 4 drives the fixing plate 5 to lower the test probe 15. The test probe 15 contacts the test point on the product to perform the test. If the test is qualified, the alarm light 26 will not react; if it fails, the alarm light 26 will sound an alarm, thus achieving the purpose of testing. The motor 21 rotates, driving the transmission shaft 22 to rotate. The transmission shaft 22 rotates, driving the first bevel gear 23 to rotate. The first bevel gear 23 rotates, driving the second bevel gear 24 to rotate. The second bevel gear 24 rotates, driving the lead screw 8 to rotate. The lead screw 8 rotates, driving the lifting plate 9 to move. The lifting plate 9 moves, driving the test probe 15 and the transmission rod 10 to move, moving the test probe 15 into the protective shell 6. The transmission rod 10 moves, causing the baffle 11 to move. The baffle 11 moves, covering the protective shell 6 to protect the test probe 15. Motor 21 rotates in the reverse direction, causing the lifting plate 9 to drive the transmission rod 10 and test probe 15 to descend. During the movement, the transmission rod 10 drives the baffle 11 to open, removing the test probe 15 from the protective shell 6 for use, thus achieving the purpose of providing protection. Moving the pull block 27 causes the pull rod 20 to move, which in turn causes the slide rod 16 to move. The slide rod 16 then causes the connecting rod 29 to move, which in turn causes another slide rod 16 to move. The slide rod 16 then causes the snap-fit ​​connector 17 to move, disengaging it from the snap-fit ​​hole 18. The test probe 15 is then removed, and the mounting rod 14 on the new test probe 15 is inserted into the mounting base 13. The slide rod 16, under the action of the tension spring 19, snaps into the snap-fit ​​hole 18, fixing it in place. This completes the replacement process, facilitating the replacement of the test probe 15.
