Background technology
Former main application progressively expands to civilian industry department by defence and military department, the application first-class as numerically-controlled machine, robot and motor to optical electric axial angle encoder as a kind of sensor.Before the utility model was made, in prior art, former AC and DC servo electrical machinery system was that realization speed is fast, position ring detects, and except that adopting corresponding sensor, its rotor magnetic pole position detects other sensors such as generally adopting Hall.Optical electric axial angle encoder can be made speed ring, position probing can detect the rotor position of magnetic pole again, but its structure is complicated, and axial dimension is bigger than normal, can not be applied on the sewing machine servomotor usable range limitation; Owing to adopt the restriction of components and parts preparation, can only be applied to industries such as numerically-controlled machine, and the manufacturing cost height.
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; Reduced axial dimension, the user need not to use speciality tool and adjusts and just can install and use rapidly; Reduce component number, reduced manufacturing cost; Adopted a sensor just to satisfy the optical electric axial angle encoder of requirement of the control signal of servomotor.
Main solution of the present utility model is achieved in that
The utility model mainly adopts main shaft 4 to be installed on the main body 1, fixing photoelectric subassembly 2,6 on the main body 1, and grating dish 3 is installed on 4, and control circuit board 7 and cable 8 are installed respectively on 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; Reduced axial dimension, the user need not to use speciality tool and adjusts and just can install and use rapidly; Because photoelectric subassembly has taked the space phase-splitting to arrange, can make A, the output of B signal of the existing detection position of this product, speed, U, the V, the output of W signal that detect the rotor position of magnetic pole arranged again simultaneously, adopted a sensor just to satisfy the requirement of the control signal of servomotor; Reduced component number, reduced manufacturing cost, usable range is wide, can be widely used in textile machine, light industry and machinery, office automation etc., is particularly useful for sewing machine, intelligent sewing machine etc.

8Connect U, V, W and A, B pattern.U, V, W and the A that grating dish 3 is arranged according to certain rules, B pattern by the optical gate effect of the logical light of photoelectric subassembly, obstructed light, form the photocurrent of analog sine.Handle A, the B signal of promptly exportable reflection machine shaft position, U, the V of reflection motor pole position relation, the square wave (or sinusoidal wave) of W signal again through differential comparator circuit, amplification and rectification circuit, driving circuit.The user can handle use according to this square wave (or sinusoidal wave) in subsequent conditioning circuit.
When user's axle rotates drive main shaft 4 rotation synchronously, the integrated electro assembly 2,6 that grating dish 3 also rotates and passes through successively to arrange by the space phase-splitting, at this moment will and change electric signal into printing opacity on the grating dish 3 or the reception of lighttight signal, the logical circuit of forming by the electron device on integrated electro assembly 2,6 and the control circuit board 7 is treated as the square wave or the sinewave output of the code on the reflection grating dish 3 again.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.
