Description

Technical Field

[0001] This utility model relates to the field of fixing device technology, specifically a chip testing fixing device. Background Technology

[0002] Chip testing fixtures are devices used to fix chips during chip testing, ensuring that the chips maintain a stable position and orientation during testing for accurate testing. Because chips are small in size, have complex structures, and have extremely high requirements for the testing environment, specialized fixtures must be used to ensure the accuracy and reliability of the tests.

[0003] For example, the patent with announcement number CN215866826U (a chip testing fixing device) includes a base plate, a chip placement stage is provided on the end face of the base plate, and transverse moving screws are symmetrically connected to the left and right side walls of the chip placement stage via bearings. A transverse rotating knob is provided on the other end face of the transverse moving screw, and a transverse moving slider is sleeved on the transverse moving screw. A transverse moving groove is opened at the bottom of the transverse moving slider, and a transverse moving rail is installed in the transverse moving groove.

[0004] While the aforementioned existing technology uses lead screw drive to fix the chip, making the chip more stable, it requires turning the lead screw in three directions during chip fixing, which is not convenient for quick chip positioning and fixing, and has poor practicality. Therefore, there is an urgent need in the market to develop a chip testing and fixing device to help people solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to provide a chip testing and fixing device to solve the problem mentioned in the background art that it is inconvenient to quickly position and fix the chip during chip fixing, resulting in poor practicality.

[0007] Preferably, a rubber pad one is fixedly installed on the inner side of the positioning plate, and a rubber pad two is fixedly installed on the inner side of the movable plate.

[0008] Preferably, a handwheel is fixedly installed below the lead screw.

[0010] Preferably, guide strips are symmetrically fixedly installed on both sides below the translation block, and slots are symmetrically provided on both sides inside the fixed plate. The guide strips and slots are positioned correspondingly, and the lower end of the guide strip slides through the slots through the fixed plate.

[0011] Preferably, a rotating cap is provided above the fixing plate, and a threaded rod is fixedly installed below the rotating cap. The threaded rod is threadedly connected to the fixing plate, and the lower end of the threaded rod extends into the interior of the slot and contacts the guide plate.

The bottom rollers are rotatably connected to the translation block, and the lower ends of the bottom rollers extend to the bottom of the translation block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model adopts a combination structure of an L-shaped positioning plate and a movable plate, combined with a single-axis lead screw drive, which can realize the rapid clamping and positioning of the chip in the horizontal direction, reducing the complicated operation of traditional three-way adjustment. Furthermore, the movable plate achieves linear movement through the threaded transmission of the translation block and the lead screw, which can not only ensure clamping stability, but also prevent displacement through the self-locking characteristic of the lead screw, thus increasing its practicality.

[0015] This utility model incorporates two rubber pads, one of which has good elasticity and cushioning properties. These rubber pads can cushion the chip when it is clamped, preventing damage caused by direct rigid clamping and effectively protecting the chip's integrity, thus increasing its practicality.

[0016] This utility model provides guidance for the linear movement of the translation block through the cooperation of the guide plate and the slot, so that the translation block can maintain a stable movement trajectory during the movement, avoid the translation block from deviating or shaking during the movement, and improve the stability of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1-4 An embodiment of this utility model provides a chip testing fixing device, including a device base plate 1, a positioning plate 2 fixedly installed above the front end of the device base plate 1, a movable plate 3 arranged below the positioning plate 2 along the front end of the device base plate 1, both the positioning plate 2 and the movable plate 3 are L-shaped plates, a translation block 4 fixedly installed below the movable plate 3, a fixing plate 5 arranged below the translation block 4, the fixing plate 5 being fixedly connected to the device base plate 1, and a lead screw 6 rotatably installed in the middle below the translation block 4, the lower end of the lead screw 6 passing through the fixing plate 5 and threadedly connected to the fixing plate 5.

[0024] By employing a combination structure of L-shaped positioning plate 2 and movable plate 3, coupled with a single-axis lead screw drive, the chip can be quickly clamped and positioned in the horizontal direction, reducing the complex operation of traditional three-way adjustment. Furthermore, the movable plate 3 achieves linear movement through the threaded transmission of translation block 4 and lead screw 6, ensuring clamping stability while preventing displacement through the lead screw's self-locking characteristic. This simplifies the operation steps while ensuring fixed reliability. At the same time, the fixed installation of positioning plate 2 and the unidirectional adjustability of movable plate 3 complement each other, meeting the adaptation requirements of chips of different sizes while avoiding the time loss of multi-directional adjustment, thus comprehensively improving testing efficiency and operational convenience.

[0025] Furthermore, a rubber pad 8 is fixedly installed on the inner side of the positioning plate 2, and a rubber pad 9 is fixedly installed on the inner side of the movable plate 3.

[0026] The rubber pads 8 and 9 are designed to provide good elasticity and cushioning performance. They can act as a buffer when the chip is clamped, preventing damage to the chip due to direct rigid clamping and effectively protecting the chip's integrity. In addition, the relatively rough surface of the rubber pads can increase the friction between the chip and the chip, making the chip more stable during testing and less prone to slipping or shifting, thus improving the reliability of the test.

[0027] Furthermore, a handwheel 7 is fixedly installed below the lead screw 6.

[0028] The handwheel 7 is designed so that rotating the handwheel 7 can drive the lead screw 6 to rotate, which increases the convenience of rotating the lead screw 6.

[0029] Furthermore, long grooves 101 are symmetrically provided on both sides of the front end face of the device base plate 1 to facilitate chip removal.

[0030] The long groove 101 makes it easier for operators to reach into the device to remove the chip, avoiding the difficulty of chip removal caused by the small operating space and improving the convenience of operation.

[0031] Furthermore, guide plates 10 are symmetrically fixedly installed on both sides below the translation block 4, and slots 501 are symmetrically provided on both sides inside the fixed plate 5. The guide plates 10 and slots 501 are positioned correspondingly, and the lower end of the guide plates 10 slides through the fixed plate 5 through the slots 501.

[0032] The cooperation between the guide plate 10 and the slot 501 provides guidance for the linear movement of the translation block 4, enabling the translation block 4 to maintain a stable motion trajectory during movement, avoiding deviation or shaking of the translation block 4 during movement, and improving the stability of the device.

[0033] Furthermore, a rotating cap 11 is provided above the fixing plate 5, and a threaded rod 12 is fixedly installed below the rotating cap 11. The threaded rod 12 is threadedly connected to the fixing plate 5, and the lower end of the threaded rod 12 extends into the interior of the slot 501 and contacts the guide plate 10.

[0034] The rotating cap 11 and threaded rod 12 facilitate the positioning of the guide plate 10, further improving the stability of the movable plate 3 and contributing to the stable fixing of the chip.

[0035] Furthermore, bottom grooves 401 are symmetrically arranged on the lower sides of the inside of the translation block 4. Bottom rollers 13 are arranged inside the bottom grooves 401 and are rotatably connected to the translation block 4. The lower end of the bottom rollers 13 extends to the lower part of the translation block 4.

[0036] The rotation of the bottom roller 13 can reduce the friction between the translation block 4 and the device base plate 1 during the movement, making the movement of the translation block 4 smoother, reducing the direct friction between the translation block 4 and the device base plate 1, reducing the wear on the device base plate, and extending the service life of the device.

[0037] Working principle: During chip testing and fixing, the chip is placed inside the positioning plate 2. By rotating the handwheel 7, the lead screw 6 is rotated, causing the translation block 4 to move the movable plate 3 linearly in the horizontal direction. By adopting the combination structure of the L-shaped positioning plate 2 and the movable plate 3 and the single-axis lead screw drive, the chip can be quickly clamped and positioned in the horizontal direction. During the clamping process, the rubber pad 8 on the inner side of the positioning plate 2 and the rubber pad 9 on the inner side of the movable plate 3 play a buffering role, preventing the chip from being damaged by direct rigid clamping, and increasing the friction between the chip and the plate, making the chip more stable. The guide strip 10 below the translation block 4 cooperates with the slot 501 inside the fixing plate 5 to provide guidance for the linear movement of the translation block 4, ensuring that the translation block 4 maintains a stable movement trajectory during the movement and avoiding deviation or shaking.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
