Abstract
Description
Technical Field
[0001] This application relates to the field of detection and adjustment equipment technology, and in particular to a high-precision repeatable positioning adjustment device. Background Technology
[0002] In semiconductor equipment and other precision testing equipment, some functional components need to be disassembled or moved during equipment maintenance to allow space for maintenance operations. For precision mechanisms installed inside the equipment, their working positions often require fine adjustment to meet operational requirements. Therefore, during initial installation, fine-tuning structures are often used to precisely adjust the positions of components. To facilitate maintenance, some equipment incorporates movable or obstacle-avoiding structures, allowing relevant components to be moved away during maintenance and then returned to their original working positions after maintenance.
[0003] However, in existing technologies, when components are reset after maintenance, the reset position often fails to match the original position, thus requiring readjustment. Frequent re-adjustments not only increase equipment maintenance time but also place higher demands on maintenance personnel. Furthermore, during repeated disassembly or reset, insufficient stability of the positioning structure can lead to accumulated positional deviations, affecting the operational stability of the equipment.
[0004] It should be noted that the above content is not necessarily prior art, nor is it intended to limit the scope of patent protection of this application. Summary of the Invention
[0005] This application provides a high-precision repeatability adjustment device to solve the problem that when existing components are reset after maintenance, the reset position is often difficult to keep consistent with the original position.

[0023] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.
[0024] Please refer to the following: Figure 1 and Figure 2 This application discloses a high-precision repeatable positioning adjustment device, including a base, an adjustment component 1 disposed on the base, a motion avoidance component 2 movable relative to the adjustment component 1, a positioning component 3 disposed between the adjustment component 1 and the motion avoidance component 2, and a locking component 4 for locking the linkage slide rod 12. By providing a movable motion avoidance component 2 in the device, relevant components can be moved to an avoidance position during equipment maintenance, thereby providing space for maintenance operations; after maintenance, the positioning component 3 returns the motion avoidance component 2 to its original working position, thereby reducing the need for precision adjustment after maintenance, reducing maintenance complexity, and shortening maintenance time.
[0025] Specifically, the adjustment component 1 is mounted on the base and includes a fine-tuning mechanism 11 and a linkage slide rod 12. The fine-tuning mechanism 11 drives the linkage slide rod 12 to move. The fine-tuning mechanism 11 precisely adjusts the position of the linkage slide rod 12, allowing for accurate setting of the positions of relevant actuators during initial installation or commissioning of the equipment. After adjustment, the position of the linkage slide rod 12 can be used as a reference position for subsequent repositioning. This structure allows the equipment to achieve the required accuracy during initial commissioning, eliminating the need for frequent re-adjustments during subsequent maintenance, thus reducing maintenance workload.
[0026] Furthermore, in this embodiment, the fine-tuning mechanism 11 is configured as a micrometer. The micrometer has high displacement adjustment accuracy; rotating the micrometer causes the linkage slide 12 to undergo a small displacement along the adjustment direction, thus achieving fine position adjustment. After setting the initial position using the micrometer, the linkage slide 12 can be stably maintained at the target position. It should be noted that, without changing the basic principle of fine position adjustment through the fine-tuning mechanism 11 driving the linkage slide 12, the fine-tuning mechanism 11 can also adopt other forms of precision adjustment structures, such as a lead screw adjustment mechanism, a micrometer head structure, or an adjustment screw structure with a precision threaded pair, to adapt to different precision or structural space requirements.
[0027] Specifically, the motion avoidance component 2 is mounted on the base and can move relative to the adjustment component 1. During equipment maintenance, the motion avoidance component 2 can be moved to an avoidance position, providing sufficient operating space for maintenance personnel. After maintenance, the motion avoidance component 2 can be moved back to the working position. This configuration allows for the acquisition of operating space without disassembling a large number of structural components during maintenance, thereby reducing disassembly and assembly steps and improving maintenance efficiency. Furthermore, the motion avoidance component 2 can be configured to slide with the base, for example, using a slide rail guide structure or a linear guide structure to ensure stability during movement. It should be noted that, provided it can move relative to the adjustment component 1, this moving structure can also adopt a roller guide structure, a slider guide structure, or a guide groove structure, etc., to adapt to different equipment structural layouts.
[0028] Specifically, the positioning component 3 is disposed between the adjustment component 1 and the motion avoidance component 2. The positioning component 3 includes mutually cooperating spherical positioning elements. Further, the spherical positioning elements include a first spherical positioning element disposed on the adjustment component 1 and a second spherical positioning element disposed on the motion avoidance component 2. When the motion avoidance component 2 moves back to its working position, the two spherical positioning elements contact each other and form a positioning relationship. Because spherical contact can automatically correct minor assembly deviations during the contact process, the contact position stably falls within the predetermined area, thus facilitating a stable and repeatable positioning effect. By adopting a spherical positioning structure, a relatively consistent positioning position can be maintained even after multiple movements and resets of the motion avoidance component 2, thereby reducing the need for readjustment after reset.
[0029] Furthermore, the spherical positioning component is made of high-hardness alloy steel and is installed as an insert on the adjusting assembly 1 and the motion avoidance assembly 2. Alloy steel has high hardness and wear resistance, which reduces wear on the contact surface during repeated contact positioning processes, thereby maintaining positioning stability. By using a material with high hardness, contact deformation can be reduced during long-term use, ensuring stable positioning accuracy.
[0030] Furthermore, a positioning insert 13 can be provided on the linkage slide rod 12. The positioning insert 13 can also be made of alloy steel and installed on the linkage slide rod 12 by embedding. By providing the positioning insert 13, a stable contact relationship can be formed between the linkage slide rod 12 and the positioning component 3, thereby further improving the reliability of repeated positioning. It should be noted that, in addition to alloy steel, the positioning insert 13 can also be made of heat-treated tool steel, stainless steel, or hard alloy material. As long as it can provide high wear resistance and structural strength, it can be used as an alternative.
[0031] Specifically, the locking assembly 4 is used to lock the linkage slide bar 12. After the position adjustment is completed, the locking assembly 4 fixes the linkage slide bar 12 in the current adjustment position, so that the linkage slide bar 12 remains stable during subsequent use. With this setting, after the equipment completes the initial adjustment, the adjustment result can be kept stable, so that no precision adjustment is required again during multiple resets.
[0032] Furthermore, the locking assembly 4 may include a fixed locking block and an eccentric handle mounted on the fixed locking block. By rotating the eccentric handle, the fixed locking block can clamp the linkage slide rod 12, thereby achieving rapid locking. The eccentric structure can generate a large clamping force during rotation, ensuring the linkage slide rod 12 is stably fixed. It is also easy to operate, allowing maintenance personnel to quickly complete the locking operation after adjustment. It should be noted that, provided the linkage slide rod 12 is locked, the locking assembly 4 may also adopt a pressure plate locking structure, a bolt tightening structure, or a wedge locking structure, etc.
[0033] Furthermore, the high-precision repeatable positioning adjustment device in this application embodiment also includes a magnetic suction component 5. The magnetic suction component 5 is disposed between the adjustment component 1 and the motion avoidance component 2. The magnetic suction component 5 includes a magnet 51 and a suction frame 52 corresponding to the magnet 51. As shown in the figure, the magnet 51 is disposed on the adjustment component 1, and the suction frame 52 is disposed on the motion avoidance component 2. When the motion avoidance component 2 moves to the working position, the magnet 51 and the suction frame 52 generate an adsorption effect, thereby providing a stable adsorption force between the two components and keeping the positioning component 3 in stable contact. By setting the magnetic suction, a continuous pressing effect can be provided to the positioning component 3 after reset, thereby reducing the positioning deviation caused by vibration or small gaps.
[0034] Furthermore, a position sensor can be installed on the adjustment component 1 to detect the position signal of the motion avoidance component 2 when it resets. By collecting the detection signal from the position sensor, the reset state can be monitored, allowing for timely judgment when an abnormality occurs in the positioning state. By introducing a position sensor, the positioning state can be monitored during equipment operation, thereby improving overall operational reliability.
[0035] Furthermore, the base can be made of marble, which has good stability and a low coefficient of thermal expansion, and is often used as a stabilizing reference structure in precision equipment. By using a marble base, the impact of temperature changes or structural vibrations on the overall stability of the device can be reduced, thereby helping to maintain the relative positional stability between the adjusting component 1 and the positioning component 3.
[0036] In summary, the high-precision repeatable positioning adjustment device provided in this application embodiment achieves initial fine position adjustment by setting adjustment component 1 and fixes the adjustment result by using locking component 4. Simultaneously, structural avoidance during maintenance is achieved by motion avoidance component 2, and a stable positioning relationship is formed by the positioning component 3 composed of spherical positioning parts during reset. This allows the equipment to quickly return to its original working position after maintenance, reducing repetitive adjustment operations and improving maintenance efficiency. Furthermore, stable clamping force is provided by magnetic suction component 5, and status monitoring is performed by position sensor, further enhancing positioning stability and operational reliability. Without departing from the scope of the claims of this solution, the aforementioned fine-tuning mechanism 11, guiding mechanism, locking method, positioning material, and position sensor can all be equivalently replaced according to actual application requirements to adapt to different equipment structures and operating environments.
