Abstract
The utility model relates to an electronic multi-ring indicating grating based on a two-way or three-way vernier, which belongs to photoelectric encoder components. A first marking ring slit and a second marking ring slit are added on the indicating grating in the slit of the two-way or three-way vernier. The electronic multi-ring indicating grating has the advantages of being novel in structure, simple in design and less in slit receiving channel, can easily achieve miniaturization design of the photoelectric receiver, greatly reduces overall dimension of the photoelectric receiver, and is good in manufacture process.
Description
Technical field
The utility model belongs to the photoelectric encoder parts, refers in particular to electronics and encloses indication grating more.
Background technology
Existing absolute type encloses the indication grating of photoelectric encoder more, adopts traditional Gray code multichannel slit designs more, and grating slit way reaches more than 13, complex design, and anufacturability is poor, is difficult to realize the miniaturization Design of receiver.
Summary of the invention
The utility model provides a kind of electronics based on 2 or 3 road vernier sign indicating numbers to enclose indication grating more, and is many to solve traditional Gray code multichannel grating slit way, complex design, and anufacturability is poor, is difficult to realize the problem of receiver miniaturization.
The technical scheme of the utility model is: the additional first note circle slit, the second note circle slit on the indication grating of 2 or 3 road vernier sign indicating number slits.
The advantage of the utility model is: novel structure, and simplicity of design, slit receiving cable number is few, is easy to the miniaturization Design of photelectric receiver, has greatly dwindled the physical dimension of photelectric receiver, and anufacturability is good.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
The additional first note circle slit 2, second is remembered circle slit 3 on the indication grating of 2 or 3 road vernier sign indicating number slits 1.
On based on the indication grating of absolute type 2 or 3 road vernier sign indicating numbers, add the slit of two receiving record gratings rotation number of turns and form compound indication grating.
Claims (1)
1. the electronics based on 2 or 3 road vernier sign indicating numbers encloses indication grating more, it is characterized in that: the additional first note circle slit, the second note circle slit on the indication grating of 2 or 3 road vernier sign indicating number slits.
