Abstract
Provided is an increment type photoelectric encoder. The invention relates to the field of photoelectric coding technology. The encoder comprises a housing and a positioning body fixed in the housing and is characterized in that O type sealing rings are provided at the connecting place of the housing and the positioning body. The positioning body is connected to a main shaft through a bearing. One end of the main shaft in the housing is provided with two PCB circuit boards. A code disc is provided between the two PCB circuit boards. The PCB circuit board at the left side of the code disc is provided with a light-sensitive element and the PCB circuit board at the right side of the code disc is provided with a light source. The upper part of the housing is connected to a connector. The invention has advantages such as high resolution, high precision, simple structure, small volume, reliable use, easy maintenance and the like. A solid and beautiful aluminium alloy and a stainless steel rotating shaft are adopted, the rotating shaft is designed with double bearings, and therefore the encoder can be used in a harsh working environment. The encoder is characterized by no screw and disposable machine pressed rubber so as to prevent dusts and splashing and ensure normal work in a scurvy environment.
Description
Technical field
The present invention relates to the photoelectric coding technical field, be specifically related to a kind of incremental optical-electricity encoder.
Background technology
Scrambler (Encoder) is a kind of of sensor (Sensor) class, be mainly used to detect speed, position, angle, distance or the counting of mechanical motion, except being applied in industrial machine, the control of many motor as servo motor, BLDC servo motor all need be equipped with scrambler for motor controller as the detecting of commutation, speed and position, so range of application is quite extensive.According to detecting principle, scrambler can be divided into optical profile type, magnetic-type, induction type and condenser type.According to its scale method and signal output form, be divided into incremental encoder and absolute type encoder.The optical grating diffraction principle of utilizing photoelectric encoder realizes displacement one digital conversion, and it is a kind of light harvesting, mechanical, electrically is the digitizing pick-up unit of one.Nearly 10 in the past few years, in industries such as pharmacy, food, printing, tobacco, machineries, obtained using widely in numerous areas such as numerically-controlled machine, robot, radar, electro-optic theodolite, ground control's instrument, high precision closed loop governing system, servo-drive system.Photoelectric encoder can be defined as: a kind of opto-electronic conversion of passing through, will transport to the machinery on the axle, the sensor that the geometric displacement amount converts pulse or digital quantity to, and it is mainly used in the detection of speed or position (angle).Typical photoelectric encoder is made up of code-disc (Disk), detection grating (Mask), photoelectric switching circuit (comprising light source, photosensitive device, signaling conversion circuit), mechanical part etc.Existing photoelectric encoder resolution is lower, precision is not high, volume is big, working service is inconvenient.
Summary of the invention
Technical matters to be solved by this invention be to provide a kind of resolution height, precision height, simple in structure, volume is little, use is reliable, the incremental optical-electricity encoder that is easy to safeguard.
Technical matters to be solved by this invention realizes by the following technical solutions,
A kind of incremental optical-electricity encoder, comprise shell, the shell internal fixation has positioning body, it is characterized in that: the O RunddichtringO is equipped with in the junction of described shell and positioning body, and described positioning body connects main shaft by bearing, and described shell inner main axis one end is provided with two PCB circuit boards, between two PCB circuit boards code-disc is housed, the PCB circuit board in described code-disc left side is equipped with light activated element, on the PCB circuit board on code-disc right side light source is housed, and described shell upper is connected with connector.
Described bearing is a duplex bearing.
Described shell is an aluminum alloy material.
Described main shaft is a stainless steel.
The present invention converts the geometry of machinery displacement on the output shaft to by opto-electronic conversion the sensor of pulse or digital quantity, because photoelectric code disk is coaxial with motor, during the motor rotation, code-disc and motor are with the speed rotation, the pick-up unit of forming through light activated element detects the some pulse signals of output, through connector output, just can reflect the rotating speed of current motor again by the number of calculating per second photoelectric encoder output pulse; In addition, for judging sense of rotation, code-disc also provides the two pulse signals of 90 ° of phase phasic differences, can make the rotary inductive signal of the electronic equipment receiving axes of received pulse, can be used to realize two-way positioning control.
The invention has the beneficial effects as follows: have resolution height, precision height, simple in structure, volume is little, usefulness is reliable, be easy to safeguard, the cost performance advantages of higher, adopt firm aluminum alloy casing attractive in appearance and stainless steel rotating shaft, the design of rotating shaft duplex bearing, be applicable to harsh working environment, and do not have the disposable machine pressure of screw and add rubber seal, dustproof, the waterproof that can be implemented under the rugged surroundings are spattered immersion and product operate as normal.
