Description

Technical Field

[0001] The utility model relates to a chip testing system, in particular to a strip chip testing system, belonging to the technical field of chip testing. Background Art

[0002] With the rapid development of semiconductor technology, bar chips, due to their unique shape and high performance, have been widely used in various fields such as communications, computers, and consumer electronics. To ensure the quality and performance of bar chips during production and use, testing is particularly important.

[0003] However, when faced with irregularly shaped bar chips, these irregularly shaped chips are difficult to clamp firmly during testing due to their uneven edges and large size differences. They are prone to shaking or slipping during testing, resulting in poor contact between the bar chip and the chip tester, causing deviations in the data collected during the test. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a strip chip testing system that can achieve stable clamping during the testing process.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] A strip chip testing system includes a base plate, a chip tester is arranged above the base plate, a disc is rotatably mounted on the base plate, a plurality of test boxes are fixedly mounted on the disc, two mobile racks are symmetrically mounted on the test boxes, a plurality of telescopic rods are fixedly mounted on one side of the mobile rack, a clamp is fixedly mounted on one end of the telescopic rod, a spring is sleeved on the surface of the telescopic rod, a first slide groove is opened on the top of the base plate, a bidirectional threaded rod is rotatably mounted inside the first slide groove, a first motor connected to one end of the bidirectional threaded rod is fixedly mounted on one side of the base plate, and the mobile rack is threadedly connected to the bidirectional threaded rod.

[0007] Furthermore, two ends of the spring are respectively connected to one side of the movable frame and one side of the clamp, and the bottom of the movable frame is slidably connected to the first sliding groove.

[0008] Furthermore, a plurality of air guide grooves are provided on the top of the bottom plate, and the clamp is slidably connected to the air guide grooves.

[0009] Furthermore, second sliding grooves are provided on both sides of the inner wall of the air guide groove, and sliding blocks adapted to the second sliding grooves are fixedly installed on both sides of the clamp.

[0010] Furthermore, a plurality of mounting slots are provided on both sides of the test box, a support plate is fixedly installed inside the mounting slot, a spiral blade is rotatably installed on one side of the support plate, and a second motor connected to one side of the spiral blade is fixedly installed on the other side of the support plate.

[0011] Furthermore, a groove adapted to the disc is provided on the upper surface of the base plate, and a third motor connected to one side of the disc is fixedly mounted on the bottom of the base plate.

[0012] Furthermore, a hydraulic rod is fixedly mounted on the upper surface of the base plate, and the hydraulic rod is connected to one side of the chip tester.

[0013] Furthermore, two bases are symmetrically installed at the bottom of the base plate, and a plurality of threaded holes are opened on the bases.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present application starts the first motor to drive the bidirectional threaded rod to rotate and bring the two clamps closer to each other until the clamps and the bar chip are against each other to clamp the bar chip. For irregularly shaped bar chips, since each clamp can squeeze the spring and the telescopic rod inward to shrink, the setting of the spring and the telescopic rod allows each clamp to be adjusted in position according to the size of the irregular bar chip, ensuring that each clamp can be against the bar chip, avoiding shaking or slipping during the test of the bar chip, resulting in poor contact between the bar chip and the chip tester, resulting in deviations in the data collected during the test.

[0023] In this embodiment, the chip tester 22 is configured to test bar chips; when clamping the bar chip, the first motor 10 is started to drive the bidirectional threaded rod 9 to rotate and then drive the two clamps 6 closer to each other until the clamps 6 are against the bar chip to clamp the bar chip; when clamping an irregularly shaped bar chip, each clamp 6 can squeeze the spring 7 and the telescopic rod 5 inward to contract. Through the configuration of the spring 7 and the telescopic rod 5, each clamp 6 can be adjusted in position according to the size of the bar chip to be tested, ensuring that each clamp 6 is against the bar chip to be tested, avoiding shaking or slipping when testing the bar chip, resulting in poor contact between the bar chip and the chip tester 22, and causing deviations in the data collected during the test.

[0024] like Figure 1-Figure 3 As shown, a plurality of air guide grooves 11 are provided on the top of the base plate 1, the clamp 6 is slidably connected to the air guide groove 11, and second sliding grooves 12 are provided on both sides of the inner wall of the air guide groove 11, and sliders 13 adapted to the second sliding grooves 12 are fixedly installed on both sides of the clamp 6.

[0025] In this embodiment, the second sliding groove 12 and the slider 13 are provided so that the clamp 6 will not deviate from the direction when moving inside the air guide groove 11, and the friction resistance can be reduced, so that the movement of the clamp 6 is smoother.

Through the setting of the spring 7 and the telescopic rod 5, the position of each clamp 6 can be adjusted according to the size of the bar chip to be tested, ensuring that each clamp 6 is against the bar chip to be tested, avoiding shaking or slipping when testing the bar chip, resulting in poor contact between the bar chip to be tested and the chip tester 22, resulting in deviations in the data collected during the test.
