[0002] In semiconductor manufacturing equipment, components such as wafer materials or large robotic arm bases move on the equipment. In these mechanical transmission systems, the interaction between a slider and a guide rail is a common mode of motion and crucial for achieving precise motion control. However, due to limitations in processing precision, slider wear, and environmental factors, the slider's movement on the guide rail may become unstable, such as wobbling or excessive tightness. This severely affects the accuracy and reliability of the mechanical system and can also lead to equipment malfunctions and reduced lifespan. Currently, although some slider designs incorporate adjustment devices, most are complex in structure, inconvenient to adjust, and fail to quickly and effectively solve the aforementioned problems.
