[0014] The beneficial effects of the present invention are:

[0015] Compared with the existing linear slides, the present invention uses the combination of a sensing sheet and a sensor to accurately detect the position of the slider on the guide rail. When the slider moves, changes will occur between the sensing sheet and the sensor. Through the signal feedback of the sensor, the position of the slider can be accurately determined. This high-precision position detection can meet the application scenarios with high requirements for the position control accuracy of the linear slide. Guide rails are arranged on both sides of the guide rail, and a built-in groove is arranged under the guide rail, and the sensing groove is close to one end of the guide rail. This compact structural design makes the size of the entire linear slide smaller and occupies less space. This is very beneficial for application scenarios with limited space and can effectively save space resources. The slider can be slidably set on the guide rail, and the sensing sheet extends into the sensing groove. Through this structural design, the movement of the slider on the guide rail is more stable and is not prone to shaking or offset. This helps to improve the motion control accuracy and stability of the linear slide and ensure the normal operation of the system.

[0016] The induction component of the present invention includes a seat body and an inductor, and a mounting groove is provided on the seat body, and the inductor is installed on the mounting groove. This design makes the installation and debugging of the inductor easier. The inductor can be adjusted and replaced as needed to adapt to different application requirements. At the same time, the mounting groove on the seat body also provides a flexible installation method, which is convenient for users to install and maintain. Sturdy guide rails and slider materials are used, specifically SKD11 or DC53 materials, and are ground and formed after quenching, with high durability and reliability. The design of the induction component has also been fully considered to ensure its stability and long-term reliable working performance. This high reliability and durability makes the linear slide solution suitable for long-term use in various industrial and automation fields. Due to the matching design between the slider and the guide rail, the solution can achieve lower friction and noise levels. This is very important for application scenarios with lower noise requirements, and can provide a quieter and more comfortable working environment.

[0017] The present invention has the technical effects of high-precision position detection, compact structural design, stable motion control, simple installation and debugging, high reliability and durability, and low friction and noise, etc. These technical effects make the linear slide scheme suitable for various industrial automation application fields of precision positioning and motion control.

[0018] In addition, the built-in sensing structure embeds the sensor into the slider and the base, so that the sensor does not require additional installation space. This can reduce the size and space occupied by the entire system, and improve the compactness and integration of the system. The built-in sensing structure integrates the sensor and the base, simplifying the installation process of the sensor. No additional fixing brackets or connectors are required, reducing installation work and time. Since the sensor directly cooperates with the sensor sheet on the slider for position detection, the built-in sensing structure can achieve more accurate position control. The direct contact between the sensor and the slider eliminates the error source that may exist in the traditional external sensing structure, and improves the positioning accuracy and stability of the system.

[0032] The guide rail 11 includes an upper arc surface 111, a convex strip 112, a lower arc surface 113 and a connecting arc surface 114 which are arranged in sequence from top to bottom. The slider 2 is provided with a slide groove 22 which cooperates with the guide rail 11 to cooperate with the upper arc surface 111, the convex strip 112 and the lower arc surface 113 for guiding sliding.
