Description

Technical Field

[0001] The utility model relates to the field of grating sensors, in particular to a grating sensor. Background Art

[0002] A sensor is a detection device and the primary link to achieve automatic detection and automatic control. The characteristics of sensors include: miniaturization, digitization, intelligence, multi-function, systematization, and networking. Usually, they are divided into ten categories according to their basic sensing functions, including thermal sensors, photosensitive elements, gas sensors, force sensors, magnetic sensors, humidity sensors, sound sensors, radiation sensors, color sensors, and taste sensors. They are widely used in various automotive, industrial, consumer and other fields. Sensors can sense the information being measured and can transform the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control.

[0003] The grating sensor is actually a special application of the photoelectric sensor. It has been widely used because of its advantages of simple structure, high measurement accuracy, easy automation and digitization. The grating is mainly composed of two parts: the scale grating and the grating reading head. Usually the scale grating is fixed on the movable part, such as the workbench or screw of the machine tool, and the grating reading head is installed on the fixed part, such as the base of the machine tool. When the movable part moves, the reading head and the scale grating also move relatively. After the current grating sensor is installed, it is not convenient to adjust the distance between the receiver and the transmitter, nor is it convenient to adjust the horizontal distance of the grating sensor. For this reason, we propose a grating sensor to solve the above problems. Utility Model Content
