A dual adjustable damping slow descent platform device

Abstract

The double-adjustable-damping slow-descending platform device designed by the application realizes three different gear adjustments through a coarse adjustment device and a fine adjustment device. First, the coarse adjustment device realizes long-distance separation or close, and when the first lifting rod of the coarse adjustment device is vertical, it is in the separation gear. The second lifting rod moves to drive the second rotating chassis to rotate, and the first lifting rod on the second rotating chassis moves accordingly. The movement of the first lifting rod drives the first rotating chassis to rotate, and then drives the load lifting rod to move to realize the movement of the load and enter the fine adjustment gear. When the second lifting rod is non-vertical and does not contact the fine adjustment device, it enters the ordinary adjustment gear, and finally realizes the rapid switching of three gears and the control of coarse and fine adjustment.

Description

Technical Field

[0001] This utility model belongs to the field of probe debugging, specifically relating to a dual adjustable damping slow descent platform device. Background Technology

[0002] With the continuous advancement of the semiconductor industry, verification often requires the use of relevant testing equipment during the design and verification phases. However, traditional probe stations typically only have a single adjustment range, a small travel distance, and no buffer design, making it difficult to meet the protection requirements for the lifespan of the samples under test and the testing equipment. This design not only fails to guarantee testing accuracy and speed but also cannot effectively ensure the long-term reliability of the equipment. Although traditional probe stations are easy to operate, modern semiconductor and integrated circuit testing has extremely stringent accuracy requirements; even the smallest error can lead to inaccurate test results.

[0003] The primary goal of the lift lever design is to ensure precise probe positioning, enabling accurate control of the probe contact point's height and pressure to achieve micron-level precision. While traditional single-stage lift lever designs offer a small travel range suitable for initial contact and fine-tuning to ensure stable probe positioning within the designated test area, they are insufficient for high-frequency, high-precision operating environments. Therefore, lift lever systems require high-strength materials and high-quality damping components to ensure long-term, stable use and maintained accuracy.

[0004] Considering future technological advancements, there is an urgent need for a more refined lever design with multi-level adjustable travel to meet the demands of higher precision and diverse application scenarios. This innovative design will ensure the equipment's high efficiency and stability during long-term operation, while simultaneously improving the accuracy and reliability of testing.

[0036] Example 1

[0037] Please refer to Figure 1 This embodiment mainly introduces a dual adjustable damping descent platform device, including a coarse adjustment device 1, a fine adjustment device 2 and a base 3;

[0038] The coarse adjustment device 1 is located on the top left side of the base 3;

[0039] The fine adjustment device 2 is located on the top right side of the base 3.

[0040] The coarse adjustment device is used to move the load, and the fine adjustment device's main function is to perform micro-control on the coarse adjustment device when the coarse adjustment device is close to the fine adjustment device.

[0041] Furthermore, the coarse adjustment device 1 includes a first lifting rod 4 and a first rotating base 5;

[0042] The first lifting rod 4 is fixed to the side of the first rotating base 5; the movement of the first lifting rod 4 can naturally drive the first rotating base 5 to rotate.

[0043] A rotating shaft is fixedly installed at the bottom center of the first rotating chassis 5, and the rotating shaft is rotatably connected to the base 3; a load lifting rod is also installed on the bottom of the first rotating chassis 5, and the load lifting rod is connected to the load; with the above design, the first rotating chassis 5 can be rotated simply by rotating the first lifting rod 4, which in turn drives the load lifting rod to rotate, thereby realizing motion control of the load.

[0044] A damper is also provided between the load lifting rod and the load. Through the design of the damper, the movement of the load can be controlled.

[0045] Furthermore, the fine-tuning device 2 includes a second lifting rod 6, a second rotating base 7, and a fixing block 8;

[0046] The bottom of the second lifting rod 6 is fixedly connected to the second rotating base 7. The bottom outer side of the second rotating base 7 is provided with a rotating shaft. The other end of the rotating shaft is connected to the fixed block 8 to realize the rotational connection between the second rotating base 7 and the fixed block 8.

[0047] Please refer to Figure 2 The second lifting rod 6 rotates, which in turn drives the second rotating chassis 7 to rotate. Since there is a rotating shaft on the outer bottom of the second rotating chassis 7, the rotation of the second rotating chassis 7 is not stationary. Therefore, when it rotates, the position of the first lifting rod 4, which is close to the second rotating chassis 7, can be adjusted. This adjustment is a fine adjustment, which in turn enables the first rotating chassis 5 to rotate slightly, which in turn drives the load lifting rod to move slightly, and thus drives the load to move.

[0048] The fixing block 8 is fixed to the top right side of the base 3;

[0049] The bottom of the second rotating chassis 7 is also provided with a shaft 9, and the top surface of the fixed block 8 is provided with an arc-shaped slot 10, in which the shaft 9 is located; a damper is provided on the shaft 9; this design enables the second rotating chassis 7 to move controllably in the arc-shaped slot 10.

[0050] The second rotating chassis 7 is arc-shaped.

[0051] Furthermore, the side wall of the arc-shaped slot 10 is also provided with three evenly spaced insertion holes 11, please refer to... Figure 3 A pin can be inserted into the socket 11 to limit the movement of the insert shaft 9.

[0052] This application utilizes the movement of the second lifting rod to drive the rotation of the second rotating chassis. At this time, the first lifting rod, which is close to the second rotating chassis, moves accordingly. The movement of the first lifting rod drives the rotation of the first rotating chassis, which in turn drives the load lifting rod to move, thereby realizing the movement of the load. If a large-scale movement of the load is desired, the movement of the first lifting rod can be directly controlled. When the first lifting rod is controlled vertically, it is in the disengagement position. When the first lifting rod contacts the fine adjustment device, it enters the fine adjustment position. When the second lifting rod is not vertical and does not contact the fine adjustment device, it enters the normal adjustment position, ultimately achieving rapid switching between three positions and control of coarse and fine adjustments.

[0053] The above description is merely a preferred embodiment of this utility model and does not limit the scope of protection of this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any changes, modifications, substitutions, integrations, and parameter alterations made to these embodiments within the spirit and principles of this utility model, through conventional substitutions or methods that achieve the same function without departing from the principles and spirit of this utility model, fall within the scope of protection of this utility model.
