Description

Technical Field

[0001] The utility model relates to the technical field of guide rail appliances, and particularly relates to an automatic controllable guide rail realized by an encoder. Background Art

[0002] A rotary encoder is a precision measuring device that closely combines machinery and electronics. Rotary encoders are generally used for measuring mechanical angles, speeds, and positions. It converts a mechanical geometric displacement into an electronic signal through photoelectric or electromagnetic principles. This electronic signal usually needs to be connected to a control system (e.g., PLC, high-speed counting module, frequency converter, etc.), and the control system can obtain the measured data through calculation for the next step of work.

[0003] A slide rail is a linear guide device used in mechanical systems. It mainly consists of a slider, a guide rail, and a guide rail seat. The slider can move smoothly on the guide rail to achieve the translation or positioning of workpieces or equipment. When a force is applied or the slider is pushed, the slider will move along the guide rail and be supported and guided by the guide rail to ensure the stability and accuracy of the movement trajectory. Slide rails usually use bearings and guiding devices to reduce friction and ensure smooth movement.

[0004] During the operation of various mechanical system devices, it is often necessary to convey materials or equipment through a slide rail, or transmit them to a certain position for direct mechanical or manual operation. Usually, the slide rail is pushed to a fixed point position by manpower for operation. This not only increases labor costs and time costs but also does not conform to automated modern operations.
