Abstract
Description
Technical Field

[0002] An encoder is a device that compiles and converts signals (such as bit streams) or data into signal forms that can be used for communication, transmission and storage. The encoder converts angular displacement or linear displacement into electrical signals. The former is called a code disk, and the latter is called a code ruler. According to the readout method, encoders can be divided into contact and non-contact types; according to the working principle, encoders can be divided into incremental and absolute types.
[0003] The current ultra-micro incremental photoelectric encoder has poor waterproof performance. When used in a dark and humid environment, moisture may penetrate into the inner cavity of the ultra-micro incremental photoelectric encoder, causing damage to the internal components of the ultra-micro incremental photoelectric encoder and a short circuit, which makes the ultra-micro incremental photoelectric encoder unable to work normally. At the same time, the wear resistance of the ultra-micro incremental photoelectric encoder is poor. During the long-term use of the ultra-micro incremental photoelectric encoder, the surface of the ultra-micro incremental photoelectric encoder will be worn. The wear will cause the ultra-micro incremental photoelectric encoder to be damaged and scrapped, which greatly reduces the service life of the ultra-micro incremental photoelectric encoder.
