Description

Technical Field

[0001] This utility model relates to the field of chip testing technology, and in particular to a chip support device for chip testing. Background Technology

[0002] In the chip manufacturing process, in order to ensure product quality, it is necessary to conduct rigorous electrical performance, functional and reliability tests. Chip testing usually requires placing the chip precisely on a special support device and contacting the chip's pins or solder joints with test probes or test sockets to complete signal transmission and testing.

[0003] Existing chip support devices mostly use simple clamps or vacuum adsorption to position the chip. However, during the testing process, especially when testing chips from multiple angles and positions, the clamps or pressure plates used for fixing often obstruct the corner areas of the chip, preventing these areas from being directly accessed by the testing equipment. For comprehensive testing, it is usually necessary to stop the machine and manually readjust the chip's clamping position or replace the clamps. This is not only cumbersome and inefficient, but the accuracy of manual adjustments is also difficult to guarantee, easily affecting the accuracy of the test results and severely restricting the automation level and production efficiency of chip testing. Utility Model Content

[0004] The purpose of this invention is to provide a chip support device for chip testing. By combining a rotating component and a swinging component, it solves the problems of incomplete chip testing caused by the clamps obstructing the chips in the prior art, which necessitates manual adjustment and is inefficient.

[0005] The technical solution of this utility model is as follows: a chip support device for chip testing, comprising a base, a support column fixedly connected to the inner cavity of the base, a support disk fixedly connected to the top of the support column, a frame disposed on the top of the support disk, a toothed ring rotatably connected to the surface of the support disk, a rotating assembly disposed on the surface of the base, the rotating assembly comprising a drive motor fixedly connected to the surface of the base, a drive gear fixedly connected to the output shaft of the drive motor, the drive gear meshing with the toothed ring, a movable disk fixedly connected to the bottom of the toothed ring via a limiting telescopic rod, a swing assembly disposed on the top of the movable disk, the swing assembly comprising a dual-axis motor fixedly connected to the top of the movable disk, a bevel gear set fixedly connected to the output shaft of the dual-axis motor, a worm fixedly connected to one side of the bevel gear set, a worm wheel meshing with the surface of the worm, a rotating shaft fixedly connected to the axis of the worm wheel, a clamping plate fixedly connected to one end of the rotating shaft, a hydraulic telescopic rod fixedly connected to the inner cavity of the base, and a drive disk fixedly connected to the telescopic end of the hydraulic telescopic rod.

[0006] Preferably, the bevel gear set includes a first bevel gear fixedly connected to the output shaft of the dual-shaft motor, a second bevel gear meshing with the surface of the first bevel gear, and the shaft center of the second bevel gear fixedly connected to the surface of the worm.

[0007] Preferably, one end of the worm gear is rotatably connected to a mounting plate via a bearing seat, and the mounting plate is fixedly connected to the top of the movable disk.

[0008] Preferably, one end of the rotating shaft is rotatably connected to the top of the movable disk via a bearing seat, and the top of the toothed ring is provided with a through hole adapted to the rotating shaft, the diameter of which is larger than the diameter of the rotating shaft.

[0009] Preferably, the drive disk is located at the center of the movable disk.

[0010] The beneficial effects of this utility model are as follows: Through the cooperation of the swing component and the hydraulic telescopic rod, the clamping plate can automatically swing open when picking up and placing chips, so that the top of the chip is completely exposed, which facilitates loading and unloading of automated equipment. When it is necessary to inspect the clamped part of the chip, the clamping plate is released by the hydraulic telescopic rod, and then the rotating component is used to drive the entire clamping mechanism to rotate a certain angle, so that the previously blocked part becomes exposed. Then, it is pressed down again to fix it for inspection. The whole process realizes the automatic switching of the chip clamping point without manual intervention, ensuring that every side of the chip can be inspected, improving the comprehensiveness of inspection, the degree of automation and work efficiency.

[0018] 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. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example 1

[0020] Please see Figures 1-5 This is the first embodiment of the present invention, which provides a chip support device for chip testing, including a base 1, a support column 2 fixedly connected to the inner cavity of the base 1, a support disk 3 fixedly connected to the top of the support column 2, a frame 4 disposed on the top of the support disk 3, a toothed ring 5 rotatably connected to the surface of the support disk 3, a rotating assembly 6 disposed on the surface of the base 1, a movable disk 7 fixedly connected to the bottom of the toothed ring 5 via a limiting telescopic rod, a swing assembly 8 disposed on the top of the movable disk 7, and the rotating assembly 6 including a drive motor 61 fixedly connected to the surface of the base 1, and a drive gear 62 fixedly connected to the output shaft of the drive motor 61. The 62 meshes with the toothed ring 5. The swing assembly 8 includes a dual-axis motor 81 fixedly connected to the top of the moving disk 7, a bevel gear set 82 fixedly connected to the output shaft of the dual-axis motor 81, a worm 83 fixedly connected to one side of the bevel gear set 82, a worm wheel 84 meshing with the surface of the worm 83, a rotating shaft 85 fixedly connected to the axis of the worm wheel 84, and a clamping plate 86 fixedly connected to one end of the rotating shaft 85. A hydraulic telescopic rod 11 is fixedly connected to the inner cavity of the base 1. A drive disk 12 is fixedly connected to the telescopic end of the hydraulic telescopic rod 11. The limiting telescopic rod ensures that the moving disk 7 can rotate synchronously with the toothed ring 5, while allowing the two to have a certain relative displacement in the axial direction.

[0021] During operation, the rotating shaft 85 drives the clamping plate 86 to rotate outward, completely exposing the space above the frame 4. At this time, the chip is placed inside the frame 4 from above. The dual-axis motor 81 is started. The output shaft of the dual-axis motor 81 drives the rotating shaft 85 to rotate through the bevel gear set 82, worm gear 83 and worm wheel 84. The rotating shaft 85 drives the clamping plate 86 to rotate inward, so that the clamping plate 86 is above the edge of the chip. Then, the hydraulic telescopic rod 11 is started. The hydraulic telescopic rod 11 pushes the drive disk 12 to move downward. The drive disk 12 drives the moving disk 7 to move. The moving disk 7 drives the entire swing assembly 8 to move downward, thereby moving the clamping plate 86 downward and pressing down to fix the edge of the chip. At this time, the clamping plate 86 will cover part of the chip area.

[0022] After this area is inspected, the hydraulic telescopic rod 11 retracts and resets, disengaging the clamping plate 86 from the chip. Subsequently, the drive motor 61 starts, and its output shaft drives the toothed ring 5 to rotate via the drive gear 62. The toothed ring 5 drives the moving disk 7 to rotate by a set angle via the limit telescopic rod, causing the chip portion previously covered by the clamping plate 86 to rotate into the inspection area. The hydraulic telescopic rod 11 extends again, pushing the moving disk 7 upward via the drive disk 12. The clamping plate 86 then clamps and fixes the chip again. At this point, the previously covered portion is completely exposed, and the inspection equipment can inspect this portion. This allows for comprehensive inspection of all areas of the chip without disassembling it.

[0023] Example 2

[0024] Please see Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0025] Specifically, the bevel gear set 82 includes a first bevel gear 821 fixedly connected to the output shaft of the dual-shaft motor 81, a second bevel gear 822 meshing with the surface of the first bevel gear 821, the shaft of the second bevel gear 822 being fixedly connected to the surface of the worm gear 83, and one end of the worm gear 83 being rotatably connected to a mounting plate 9 via a bearing seat, and the mounting plate 9 being fixedly connected to the top of the movable disk 7.

[0026] The bevel gear set 82 is used to change the transmission direction, transmitting the horizontal rotational power of the dual-axis motor 81 to the vertical worm 83. The mounting plate 9 and bearing seat provide stable rotational support for the worm 83, ensuring the smoothness of the transmission. The self-locking characteristics of the worm wheel 84 and worm 83 ensure the stability of the clamping state. The swing opening method of the clamping plate 86 makes the space above the frame 4 completely exposed when the chip is placed, which is convenient for the automated robotic arm to place the chip from top to bottom and avoids the interference of traditional grippers.

[0027] Example 3

[0028] Please see Figures 1-5This is the third embodiment of the present invention, which is based on the first two embodiments.

[0029] Specifically, one end of the rotating shaft 85 is rotatably connected to the top of the movable disk 7 through a bearing seat, and the top of the toothed ring 5 is provided with a through hole 10 that is adapted to the rotating shaft 85. The diameter of the through hole 10 is larger than the diameter of the rotating shaft 85, and the drive disk 12 is located at the center of the movable disk 7.

[0030] The diameter of the through hole 10 is larger than the diameter of the rotating shaft 85. This design allows the rotating shaft 85 to rotate independently of the toothed ring 5. At the same time, the through hole 10 provides clearance for the vertical movement of the rotating shaft 85, ensuring the realization of the lifting function of the clamping plate 86. The drive plate 12 is located at the center of the moving plate 7 and is not connected to the moving plate 7. The hydraulic telescopic rod 11 cooperates with the drive plate 12 to drive the moving plate 7 and the entire swing assembly 8 to lift and lower, thereby realizing the vertical pressing or releasing of the chip.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
