Abstract
The utility model relates to a compound code encoder, in particular to a device applied to automation control system such as textile machinery industry, which pertains to the technology field of automation measurement device. The utility model is characterized in that: a spindle is supported by a bearing in the main body, a grating disc seat is provided with an optoelectronic read head and a grating and a shell arranged on the main body. The structure of the utility model is simple, compact and reasonable; the circuit is simple, the process parameter can be adjusted and the output signal is stable and reliable; after the rotation of the grating, the optoelectronic read head with high integration can receive the signal on the grating disc and transform into digital electric signal and code reflecting on the grating disc is output in the form of rectangular wave (sinusoidal wave) after being treated by simple drive circuit, thereby finishing the transformation of mechanical movement physical quantity (position, speed, acceleration) towards digital signal.
Description
Technical field
The utility model relates to a kind of compound key scrambler, specifically is applied to belong to the automatic measurement mechanism technical field in the automation control systems such as textile machinery industry.
Background technology
In prior art, be used for the compound key scrambler of systems such as automatic measurement, robotization control, textile machine, mainly grade and form by main body, main shaft, precision bearing, grating and opto-electronic conversion handling part.The photoelectricity of its opto-electronic conversion processing section accepts normally to adopt the Photoelectric Detection scheme of a plurality of discrete components to produce simulating signal, converts digital signal to by treatment circuit again, then through driving output; Its production technology assembling and setting difficulty, circuit are formed complexity, yield rate is low, poor reliability, and the manufacturability that design parameter is adjusted is poor, has directly influenced precision, the stability of output signal.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of compound key scrambler, signal on the grating dish directly can be extracted and change into digital electric signal, its circuit is simple, the production assembly technology is simple, output signal accuracy is high, good stability.
Main solution of the present utility model is achieved in that
The utility model mainly adopts electronic circuit board is housed in main body, the photoelectric reader of high integration is contained on the electronic circuit board, housing and main shaft are contained on the main body, feature is that main shaft is bearing in the main body by bearing and cooperates installation with grating dish seat, and the photoelectric reader and the grating of high integration is installed on grating dish seat.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Its circuit is simple, the production assembly technology is simple, output signal accuracy is high, good stability, and technological parameter can be adjusted; Photoelectric reader by high integration after grating rotates will access signal on the grating dish and change into digital electric signal, through the code on the simple processing of circuit reflection grating dish with the output of square wave group, thereby finished by the conversion of mechanical motion physical quantity (position, angle) to digital quantity.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly is made up of main shaft 1, main body 2, bearing 3, grating dish seat 4, photoelectric reader 5, grating 6 and housing 7 etc.
The utility model adopts and in main body 2 electronic circuit board is housed, and main shaft 1 is bearing in the main body 2 by bearing 3, cooperates installation with grating dish seat 4, and the photoelectric reader 5 and the grating 6 of high integration is installed on grating dish seat 4, and housing 7 is installed on main body 2.
When user's axle rotated, the main shaft 1 of this product (grating 6) also rotated thereupon synchronously, and the photoelectric reader 5 of high integration is a digital signal with the code conversion on the grating 6, again through driving output.This product fixed part is to be provided with four holes by main body 2 to be screwed on the end face of user installation.
Principle of work of the present utility model:
When user's axle rotates, the main shaft 1 of this product (grating 6) also rotates thereupon synchronously, the photoelectric reader 5 of high integration is a digital signal with the code conversion on the grating 6, exports with square wave (or sinusoidal wave) through the code that simple drive circuit is handled on the reflection grating dish.This signal output has promptly comprised the information of user's axle motion state, has finished by the conversion of mechanical motion physical quantity (position, speed, acceleration) to digital quantity.
