Abstract
The invention discloses a magneto-electric mixing type absolute value encoder being a mechanical unit comprising a main body and a main shaft installed on the main body in dual-bearing guiding mode. A magnetic source body arranged at the inner end of the main shaft emits a magnetic signal; a variable NS pole signal is generated based on rotation of the magnetic source body; and a magnetic signal collector arranged on a PCB carries out conversion to generate an analog signal. A grating disk is installed at a shoulder of a magnetic source body seat; and a light emitting source is arranged on the main body. Light emitted by the light emitting source passes through the rotating grating disk and enters a light signal collector arranged on the PCB through a slit to generate an analog signal; and after the signal is processed by a follow-up circuit, a pulse signal is outputted. According to the invention, the outer diameter of the absolute value encoder is reduced based on combination of the photoelectricity and magnetoelectricity; and the number of bit of the output pulse of the encoder can be improved.
Description
Technical field
The present invention relates to scrambler field, specifically, be related specifically to the hybrid absolute value encoder of a kind of magnetoelectricity.
Background technology
Scrambler be signal or data are carried out work out, being converted to can in order to the equipment of the signal form of communication, transmission and storage.Scrambler converts electric signal to angular displacement or straight-line displacement, and the former is called code-disc, and the latter is called yardstick.Contact and contactless two kinds can be divided into according to playback mode scrambler; Increment type and absolute type two class can be divided into according to principle of work scrambler.Photoelectric encoder and magnetism encoder can be divided into by signal source classification.Incremental encoder converts mechanical shift to periodic electric signal, then this electric signal is transformed into count pulse, represents the size of displacement by the number of pulse.
At present, absolute type encoder is mostly large external diameter lower-order digit, can not meet the requirement of market for little external diameter seniority absolute type encoder.It is primarily of main shaft, pedestal, light-emitting component and grating disc or be magnetic body, the compositions such as receiving trap, pedestal and main shaft utilize bearing to lead, grating disc and main shaft are integrated, fixing on main shaft hollow spindle being inserted in rotation mechanism, signal picker is fixed on pedestal, coordinates with the position of grating disc, when grating disc rotates, the light beam sent via light-emitting device is received by signal picker through the grating disc rotated, produce initialize signal, the number of converting to, through subsequent treatment output pulse signal, controls mechanical hook-up.Due to the problem on scrambler grating and follow-up signal process, existing absolute type can not accomplish little external diameter seniority, as more difficult in installed on small scale robot, can not meet consumers' demand.
