A counting method and counting device based on an incremental encoder

Abstract

The invention belongs to the technical field of motor encoders, and specifically relates to a counting method based on an incremental encoder and a counting device thereof. The counting method includes the following steps: S1: passing the output shaft of the motor through the center of the encoder body After that, make the output shaft of the motor coincide with the shaft center of the encoder body, and make one side of the encoder body fit the side wall of the motor, and then set the output pulse signal of the encoder; S2: Then, by placing the motor shaft The number obtained by clockwise rotation through the pulse signal is recorded as signal 1, and the signal obtained by reverse rotation is recorded as signal 2, and the signal 1 and signal 2 are output to the display in sequence; through the setting of the dust-proof elastic cloth, the The encoder body can be bonded to the encoder body during use, reducing the impurities outside the encoder body from entering into the encoder body, which will affect the optical counting of the encoder body.

Description

technical field [0001] The invention belongs to the technical field of motor encoders, in particular to an incremental encoder-based counting method and a counting device. Background technique [0002] The encoder is composed of a grating disk and a photoelectric detection device. Since the grating disk and the motor are coaxial, the grating disk and the motor rotate at the same speed. The light-emitting diode illuminates the grating disk and projects the image of the grating disk onto the photoelectric detection device composed of photosensitive elements. The light changes generated by the rotation of the grating disc are converted and output as corresponding pulse signal changes. [0003] There are also some technical solutions for motor encoders in the prior art. For example, a Chinese patent with application number 2021200737511 discloses an incremental encoder with a through-shaft hole, including an encoder body. A shaft hole is provided with a clamping part on the sha...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology and solve the problem of using in an environment with a lot of dust, impurities or oil, when impurities enter the encoder, it will have a greater impact on the optical detection of the encoder, resulting in counting errors problem, the present invention proposes a counting method based on an incremental encoder and a counting device thereof
