Description

technical field [0001] The invention relates to a grating encoder test device, more precisely, the invention relates to a grating encoder reliability test device which can apply multiple factors such as temperature, humidity, vibration and rotating speed to the grating encoder. Background technique [0002] The grating encoder is a sensor that integrates light, mechanics, and electricity and is used to measure the speed and angle of the motor. It has a wide range of uses, excellent performance, and can work in harsh environments. Grating encoder is an important part of automatic control equipment such as CNC machine tools. It integrates advanced technologies in the fields of computer, optics, and machinery. It is a high-tech product with strong disciplines and comprehensiveness, which can effectively improve the accuracy of equipment. In rotating machinery, the grating encoder uses a circular grating disk as the detection element. Because it has the advantages of high measu...
