The utility model is mainly characterized in that a main shaft is installed in a main body and supported by a shaft bearing, a grating disk is installed on the main shaft, a connecting circuit board of reflective devices are tightly fixed on the main body and a plug is installed on a casing which is also tightly fixed on the main body. The reflective photoelectric axial angle encoder has simple, reasonable and compact structure and completely meets the requirements of all new environmental protection due to the application of completely leadless process. The effect of long distance transmission can be achieved without the requirement of any additional drive circuit, so that the cost is saved. Additionally, the inner part of the reflective photoelectric axial angle encoder is provided with a short protection circuit, so that the service life of a whole rotary encoder can be effectively lengthened.
Description
Technical field
The utility model relates to a kind of reflection optical electric axial angle encoder, and displacement specifically and angle displacement sensor are mainly used in photoelectric servo system and automatic control system as detecting element or feedback element.
Background technology
Photoelectric encoder progressively is diffused into civilian industry department as a kind of sensor by defence and military department.As by at the artillery command instrument, aerospacecraft is used on the military vehicle radar and is diffused into numerically-controlled machine, robot, controls production line, motor etc. automatically.Before the utility model is made, in prior art, what the pulse signal of conventional rotary encoder generally adopted when obtaining is the transmission-type structure, promptly throw a branch of directional light in a side of grating dish, the window (slit) that this light beam sees through two blocks of dynamic and static gratings is received by the photoelectric device of opposite side, and adds the driving circuit output signal after shaping is amplified.This type of scrambler is when making, and technology is complicated, and dynamic and static grating is difficult for quasiconcentric, and phase signal is difficult for obtaining, and the signal of obtaining a little less than, need processing through shaping amplification circuit, can export stable signal, and cost of manufacture is also higher.
Technology contents
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of simple, compact and reasonable for structure; Follow-uply can add driving circuit in addition, can reach the effect of long Distance Transmission, save cost; And can prolong the whole rotary encoder reflection optical electric axial angle encoder in serviceable life effectively.
Main solution of the present utility model is achieved in that
The utility model mainly adopts main shaft 3 to be installed in the main body 1, adopts bearing 2 supportings, and grating dish 5 is housed on main shaft 3, and reflection device 8 connecting circuit plates 6 are fastened on the main body 1, plug 7 is housed on housing 4, and is fastened on the main body 1.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Because this element manufacturing has been used the skill completely without splicer, has reached brand-new environmental protection requirement fully; Follow-uply can add driving circuit in addition, can reach the effect of long Distance Transmission, save cost; And this device inside has short-circuit protection circuit, can prolong the serviceable life of whole rotary encoder effectively.
Description of drawings
Fig. 1 is the utility model structural front view.
Fig. 2 is equipped with the pillar front view for the utility model structure.
Fig. 3 is the utility model structural circuit schematic diagram.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described: the utility model is made up of three parts altogether, i.e. pivotable parts axle system, fixed part reflection photoelectric subassembly, main body and circuit part.Main shaft 3 is contained in the combined body 1, adopt bearing 2 supportings, and the user connects with main shaft 3 by shaft coupling.Grating dish 5 is housed on main shaft 3, and main shaft when user's axle rotates (grating dish 5) also rotates thereupon synchronously.Fixed part main body 1 is installed on user's the fixedly end face by the Luo hole on it.Reflection device 8 connecting circuit plates 6 adopt to be pasted or welding, and circuit board 6 usefulness screws and glue are fastened on the main body 1.The light transmitting-receiving of reflection device 8 is in the same side of grating dish 5, and its grating dish 5 has the reflection ray function.On circuit board 6, electronic circuit is housed, on the housing 4 that shields, plug 7 is housed and is fastened on the main body 1 by screw and glue.Between circuit board 6 and main body 1, adopt screw and glue fastening pillar 9 respectively.
The utility model circuit theory:
When the utility model uses in reality, end by this device is launched a branch of directional light, this light is via the reflection of the effective reflecting surface of reflection grating, and received by the receiver of this device other end, and after the processing of this device inside circuit the stable electric signal of output.Again because of this device inside integrated differential comparison, amplify shaping and driving circuit.Event is follow-up can to add driving circuit in addition, can reach the effect of long Distance Transmission, has saved cost.
The utility model principle of work:
The read method ratio of the utility model encoder pulse signal is easier to, owing on main shaft 3, fixing a grating dish 5 with reflection function, useful photoetching process is scribed on the grating dish 5, arrange according to certain rule, reflected light or not catoptrical pattern code.When user's axle rotates 3 rotations synchronously of this product of drive principle axis shafting, grating dish 5 also rotates, at this moment reflection device 8 will receive on the device 8 and changes electric signal into having reflected light or not catoptrical signal on the grating dish 5, the circuit of forming by the electron device on the circuit board 7 carries out simple process again, becomes the square wave or the sinewave output of the code on the reflection grating dish 5.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 electric weight.
