Technical Field
[0001] This utility model relates to the field of semiconductor finished product testing fixture technology, specifically a semiconductor finished product testing fixture. Background Technology
[0002] Semiconductor finished product test fixtures are key equipment in semiconductor manufacturing and back-end packaging testing, mainly used for chip functional verification, appearance inspection and reliability testing.
[0003] In many industrial fields such as electronics manufacturing and machining, test fixtures play a vital role as key tools for ensuring product quality and achieving accurate testing. However, the traditional test fixtures widely used in the industry have obvious limitations. Most traditional test fixtures are designed according to the principle of dedicated machine and dedicated product. Each test fixture can often only be adapted to a specific model or specification of product or equipment. Although it meets the testing needs of specific production scenarios to a certain extent, it brings serious problems of poor versatility.
[0004] Therefore, there is an urgent need for a semiconductor finished product testing fixture to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a semiconductor finished product testing fixture that has the advantage of being applicable to multiple specifications and solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a semiconductor finished product testing fixture, comprising a mounting base plate, a vertical connecting plate slidably connected to the surface of the mounting base plate, a support plate fixedly connected to the top of the vertical connecting plate, a cylinder seat fixedly connected to the top of the mounting base plate, a telescopic cylinder fixedly connected to the inner wall of the cylinder seat, an outer tube fixedly connected to the output end of the telescopic cylinder, an inner rod slidably connected to the inner cavity of the outer tube, the top end of the inner rod extending through to the top of the support plate, four mounting seats fixedly connected to the top of the support plate, a rotating shaft rotatably connected to the inner cavity of the mounting seats via a torsion spring, a rocker arm fixedly connected to the surface of the rotating shaft, a clamping block fixedly connected to the top of the rocker arm, a support fixedly connected to one side of each of the four mounting seats, a bearing block slidably connected to the inner cavity of the support, the bottom of the bearing block fixedly connected to the inner rod, and the inner rod cooperating with the rocker arm.

[0023] As attached Figure 1 To be continued Figure 7As shown: This embodiment provides a semiconductor finished product testing fixture, including a mounting base plate 12, a vertical connecting plate 13 slidably connected to the surface of the mounting base plate 12, a support plate 7 fixedly connected to the top of the vertical connecting plate 13, a cylinder seat 11 fixedly connected to the top of the mounting base plate 12, a telescopic cylinder 10 fixedly connected to the inner wall of the cylinder seat 11, an outer tube 9 fixedly connected to the output end of the telescopic cylinder 10, an inner rod 14 slidably connected to the inner cavity of the outer tube 9, the top end of the inner rod 14 extending through to the top of the support plate 7, four mounting seats 6 fixedly connected to the top of the support plate 7, a rotating shaft 5 rotatably connected to the inner cavity of the mounting seat 6 via a torsion spring, a rocker arm 4 fixedly connected to the surface of the rotating shaft 5, a clamping block 3 fixedly connected to the top of the rocker arm 4, a support 2 fixedly connected to the opposite side of the four mounting seats 6, a bearing block 1 slidably connected to the inner cavity of the support 2, the bottom of the bearing block 1 fixedly connected to the inner rod 14, and the inner rod 14 and the rocker arm 4 working together.
[0024] Specifically, the inner rod 14 has a guide sleeve 8 that is slidably connected to its surface, and the surface of the guide sleeve 8 is fixedly connected to the support plate 7.
[0025] In this embodiment: by setting the guide sleeve 8, the outer tube 9 will slide in the inner cavity of the guide sleeve 8 when it moves, which plays a role in guiding the outer tube 9.
[0026] Specifically, a threaded rod 15 is provided through the surface of the outer tube 9, and the threaded rod 15 and the outer tube 9 form a threaded connection, and the threaded rod 15 and the inner rod 14 are used in conjunction.
[0027] In this embodiment: by setting the threaded rod 15, the threaded rod 15 is in close contact with the inner rod 14 to achieve the relative positioning of the inner rod 14 and the outer tube 9. If you want to adjust the position between the inner rod 14 and the outer tube 9, simply reverse the threaded rod 15 so that the threaded rod 15 is away from the inner rod 14.
[0028] Specifically, the top of the mounting base plate 12 has four threaded holes 16.
[0029] In this embodiment, the threaded hole 16 facilitates the installation of the support block 1 on the machine, thereby improving the convenience of installing the support block 1.
[0030] Specifically, a guide groove 17 is provided on one side of the mounting base plate 12, and a guide block 18 is slidably connected to the inner cavity of the guide groove 17. One side of the guide block 18 is fixedly connected to the vertical connecting plate 13, and two bolts are provided through one side of the vertical connecting plate 13. The mounting base plate 12 and the vertical connecting plate 13 are detachably connected.
[0031] In this embodiment: by using the guide groove 17, guide block 18 and bolts together, when it is desired to adjust the position of the support plate 7, the bolts are removed so that the vertical connecting plate 13 drives the guide block 18 to slide in the inner cavity of the guide groove 17 to adjust the position of the support plate 7. Finally, the bolts are tightened to position the mounting base plate 12 and the vertical connecting plate 13.
[0032] The working principle and usage process of this utility model are as follows: The telescopic cylinder 10 is activated, and its output end drives the outer tube 9 to move upward. At this time, the outer tube 9, through the transmission of the inner rod 14, pushes the rocker arm 4 to rotate within the cavity of the mounting base 6. During the rotation of the rocker arm 4, the pressing block 3 rotates, causing all four pressing blocks 3 to expand outward. Simultaneously, as the inner rod 14 moves upward, it pushes the bearing block 1 to slide upward within the cavity of the support 2. The product is then placed on top of the bearing block 1, which is used to hold the product. The output end of the telescopic cylinder 10 retracts, causing the outer tube 9 and the bearing block 1 to move downward. When the thrust of the inner rod 14 on the rocker arm 4 disappears, the rocker arm 4 closes under the action of the torsion spring, thus pressing the product. When the product thickness changes, the threaded rod 15 is reversed, moving away from the inner rod 14. The inner rod 14 is adjusted upward or downward according to the product thickness, causing the bearing block 1 to adjust its height within the cavity of the support 2, thereby achieving precise positioning.
[0033] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
[0034] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
