Abstract
The utility model relates to an ultrathin split type reflection encoder, in particular to a device applied to electrical apparatus servo system and automatic control system as a detecting element or a feedback component. The utility model is characterized in that: the bottom plate is installed with an electronic circuit board and a shell is arranged on the bottom plate; a reflection optoelectronic read head is arranged on the electronic circuit board and gratings are adhered to a grating support to form grating support groups. The structure of the utility model is simple, compact and reasonable; the circuit and the technique of manufacturing setup is simple, the output signal stable and the process parameter adjustable; 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 simple treatment of circuit, thereby finishing the transformation of mechanical movement physical quantity (position, speed, acceleration) towards digital signal.
Description
Technical field
The utility model relates to the split type reflection encoder of a kind of ultrathin type, specifically is used for electrical equipment servo-drive system and automatic control system as detecting element or feedback element, belongs to a kind of novel displacement and angular transducer.
Background technology
In prior art, former common optical electric axial angle encoder, it mainly is the Photoelectric Detection scheme that adopts photoelectric cell, photoelectric tube, because the restriction of its structure, employing components and parts and configuration, can only produce the bigger binary encoding device of straight warp, its production technology assembling and setting difficulty, yield rate is low, volume is big, poor reliability, production cost height, environment for use require harsh, the anti-vibration ability.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of ultrathin type split type reflection encoder, and it has, and volume is little, the production technology assembling and setting is simple, easy for installation, cost is low, and suitable user uses in batches; Dustproof, error correcting capability is strong, reliability is high, long working life.
Main solution of the present utility model is achieved in that
The utility model mainly adopts electronic circuit board is housed on base plate, and housing is contained on the base plate, and feature is that the reflection photoelectric reader is contained on the electronic circuit board, and grating is bonded in and forms grating holder group in the grating holder.
Described base plate is provided with four mounting holes.
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, stable output signal is good, and technological parameter can be adjusted; Reflection photoelectric reader by high integration after grating rotates will access signal on the grating dish, and change digital electric signal into, through the code on the simple processing of circuit reflection grating dish with square wave group (or sinusoidal wave) output, 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 by base plate 1, electronic circuit board 2, reflection photoelectric reader 3, grating 4, grating holder 5, the user fixedly form by jackscrew 6 and housing 7 etc.
The utility model adopts electronic circuit board 2 is housed on base plate 1, and the reflection photoelectric reader 3 of high integration is contained on the electronic circuit board 2, and housing 7 is contained on the base plate 1, and grating 4 is bonded in and forms grating holder group in the grating holder 5.When with installation, this product base plate 1 is fixed on user's axial end, by the user fixedly jackscrew 6 grating holder group is fixed on user's the main shaft, when user's main shaft rotating shutter group (grating 4 and grating holder 5) is also rotated synchronously thereupon, the reflection photoelectric reader 3 of high integration is a digital signal with the code conversion on the grating 4, again through driving output.This product fixed part is to be screwed on the end face of user installation by four mounting holes on the base plate 1.
Principle of work of the present utility model:
When user's axle rotates, the grating group of this product (grating 4 and grating holder 5) is also rotated thereupon synchronously, the reflection photoelectric reader 3 of high integration is a digital signal with the code conversion on the grating 4, exports with square wave group (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.
