A support column 14 is fixedly connected to the bottom of the placement plate 2, and a circular gear 15 is fixedly connected to the support column 14. When using the fixing device for electronic chip production, the first slider 7 and the second slider 12 can be quickly adjusted by twisting the handle 1 6 and the handle 2 11, so that it can flexibly adapt to the fixing requirements of chips of different sizes and quantities, whether it is the single-chip fixing of small-size chips or the fixing of large-size chips or multiple chips at the same time, which greatly improves the versatility and flexibility of the device.

[0023] The bottom plate 1 is fixedly connected with a slide 16, a third slide groove 17 is provided on the slide 16, a slide rod 18 is slidably connected to the third slide groove 17, the bottom of the slide rod 18 is fixedly connected with a spring 19, one end of the spring 19 is fixedly connected to the slide 16, a disc 20 is fixedly connected to the slide rod 18, a gear groove 21 is provided on the disc 20, a handle 22 is fixedly connected to the disc 20, a connecting hole 23 is provided on the bottom plate 1, and the connecting hole 23 is provided with four groups. The first threaded screw 5 and the second threaded screw 10 are symmetrically arranged, the fourth fixed claw 24 and the second fixed claw 9 are symmetrically arranged, the circular gear 15 is engaged with the gear groove 21, and the support column 14 is rotatably connected to On the base plate 1, two groups of first fixing claws 8 are respectively arranged on both sides of the first slider 7, two groups of third fixing claws 13 are respectively arranged on both sides of the second slider 12, and two groups of handles 22 are respectively arranged on both sides of the disc 20. When using the fixing device for electronic chip production, by pressing down the handle 22 to unlock and pulling the placement plate 2, the chip can be flexibly rotated to any required detection angle, thereby ensuring that the probe or sensor of the detection equipment can fully cover all surfaces and corners of the chip, realizing detection without dead angles, which not only improves the accuracy and reliability of detection, but also effectively reduces the risk of quality problems caused by blind spots in detection.

[0024] Working principle: When using the fixture for electronic chip production, the staff first fixes the base plate 1 to the detection equipment bracket with bolts through the four groups of connection holes 23, and then places the chip to be tested between the second fixing claw 9 and one group of the first fixing claw 8 or the fourth fixing claw 24 and one group of the third fixing claw 13. It is also possible to simultaneously place two groups of chips between the second fixing claw 9 and one group of the first fixing claw 8 and the fourth fixing claw 24 and one group of the third fixing claw 13, and then respectively twist the handle 1 6 and the handle 2 11, which drives the first screw rod 5 and the second screw rod 6 to rotate. The screw rod 10 rotates on the placement plate 2, and the first threaded screw rod 5 and the second threaded screw rod 10 are threadedly connected to drive the first slider 7 and the second slider 12 to slide on the first slide groove 3 and the second slide groove 4. When one set of first fixing claws 8 and second fixing claws 9 and one set of third fixing claws 13 and fourth fixing claws 24 are respectively attached to the two sides of the corresponding chip, the chip is fixed. When the size of the chip to be fixed is large, first move the first slider 7 and the second slider 12 to both sides, and then place the chip in the middle of the other set of first fixing claws 8 and third fixing claws 13, and then simultaneously twist the handle 6 and The second handle 11, when the third fixing claw 13 and the first fixing claw 8 are attached to both sides of the chip, completes the fixation of the larger chip, thereby being able to flexibly adapt to the fixing needs of chips of different sizes and quantities, whether it is the fixation of a single chip of small size, or the fixation of a large chip or multiple chips at the same time, greatly improving the versatility and flexibility of the device. When it is necessary to rotate the fixed chip, the staff presses down the two sets of handles 22, and the handles 22 drive the disc 20 to move downward. The disc 20 drives the slide rod 18 to slide downward on the third slide groove 17 and compresses the spring 19 at the same time. When the gear groove 21 leaves the meshing with the circular gear 15, the staff pulls the placement plate 2 to rotate on the base plate 1 through the support column 14 to drive the chip to rotate. When the chip rotates to the required position, the handle 22 is released, and the slide bar 18 slides upward on the third slide groove 17 through the rebound effect of the spring 19. When the slide bar 18 drives the gear groove 21 on the disc 20 to re-engage with the circular gear 15, the support column 14 is fixed, thereby ensuring that the probe or sensor of the detection equipment can fully cover all surfaces and corners of the chip, thereby achieving comprehensive detection of the chip and reducing quality problems caused by blind spots in detection.
