Abstract
The utility model discloses a kind of multi-turn mechanical type absolute value encoder, comprise rotating shaft, absolute value code-disc, light source, planar light slit, opto-electronic receiver source and gear set, in described rotating shaft, cover has absolute value code-disc, described absolute value code-disc is provided with the pertusate planar light slit of band, the right-hand member of described absolute value code-disc is provided with multiple opto-electronic receiver source, the light that described opto-electronic receiver source sends for receiving light source, described rotating shaft transmission is connected with gear set, the utility model structure is simple, easy to use, break existing servo-driver structural framing, scrambler as servo-driver an accessory and driver is supporting instead of and servomotor supporting, so the application of this servo-driver is just wider, install more flexible, control effects is better.
Description
Technical field
The utility model relates to scrambler field, specifically a kind of multi-turn mechanical type absolute value encoder.
Background technology
Scrambler due to the servomotor of current servo driver drives is mostly increment type or individual pen absolute value optoelectronic encoding device, and this scrambler must be arranged on servomotor, servomotor could must mate mixing up zero point both before dispatching from the factory, but it is as follows to there is intrinsic shortcoming in such servo drive system, the shortcoming of incremental encoder: the zero point of definition that after powering on, very important person is, there is the trouble finding zero point, moreover do not allow such action in some occasion, the shortcoming of individual pen absolute value optoelectronic encoding device: individual pen absolute value encoder is as the term suggests be exactly be the scrambler of absolute position in a circle, the number of turns to be remembered by powered battery and realize multi-turn function, powered battery is depended on after driver power down, driver powers at every turn and will read previous historical record, if motor load has rotation during this period, just there is the phenomenon that data misread, if the especially error of meter circle, original absolute position cannot be found on the contrary, there are some in addition as the leakage circle in high speed, mistake circle in interference, just in time at the shake mistake circle of 12 o ' clock positions, battery failure mistake circle, often change the problems such as battery.
Utility model content
The purpose of this utility model is to provide a kind of multi-turn mechanical type absolute value encoder, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of multi-turn mechanical type absolute value encoder, comprise rotating shaft, absolute value code-disc, light source, planar light slit, opto-electronic receiver source and gear set, in described rotating shaft, cover has absolute value code-disc, described absolute value code-disc is provided with the pertusate planar light slit of band, the right-hand member of described absolute value code-disc is provided with multiple opto-electronic receiver source, the light that described opto-electronic receiver source sends for receiving light source, described rotating shaft transmission is connected with gear set.
As further program of the utility model: described gear set is made up of multiple gear.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, easy to use, break existing servo-driver structural framing, scrambler as servo-driver an accessory and driver is supporting instead of and servomotor supporting, so the application of this servo-driver is just wider, and install more flexible, control effects is better.
Accompanying drawing explanation
Fig. 1 is the structural blast figure of a kind of multi-turn mechanical type of the utility model absolute value encoder.
In figure: 1-rotating shaft, 2-absolute value code-disc, 3-light source, 4-planar light slit, 5-opto-electronic receiver source, 6-gear set.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of multi-turn mechanical type absolute value encoder, comprise rotating shaft 1, absolute value code-disc 2, light source 3, planar light slit 4, opto-electronic receiver source 5 and gear set 6, in described rotating shaft 1, cover has absolute value code-disc 2, described absolute value code-disc 2 is provided with the pertusate planar light slit 4 of band, the right-hand member of described absolute value code-disc 2 is provided with multiple opto-electronic receiver source 5, the light that described opto-electronic receiver source 5 sends for receiving light source 3, described rotating shaft 1 is connected with gear set 6, and described gear set 6 is made up of multiple gear.
Principle of work of the present utility model is: multi-turn mechanical type absolute value encoder uses the principle of watch gear machinery, add one group of gear set 6, when absolute value code-disc 2 rotates, by another group gear of gear drive, the basis of individual pen coding increases the coding of the number of turns again, to expand the measurement range of scrambler, such absolute encoder is just called true multi-turn absolute value encoder, for the numerical value of multi-turn, determine coding by mechanical location equally, eachly position encodedly uniquely not repeat, and without the need to memory, another advantage of encoder is because measurement range is large, actual use is often rich more, this servo-driver and multi-turn mechanical type absolute value encoder have coordinated closed-loop control, this scrambler can be arranged on motor shaft, also can be arranged in final drive mechanism, only need determine zero point when equipment is installed for the first time, just zero point need not be determined again in use afterwards, user also oneself can determine the position at zero point, any one position user of absolute value encoder can locate the zero point of oneself, and enormously simplify Installation and Debugging difficulty.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this instructions is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of instructions is only for clarity sake, those skilled in the art should by instructions integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
