For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the utility model embodiment and accompanying drawing, the technical scheme in the utility model embodiment is clearly and completely described.It should be noted that, 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.
Embodiment
Refer to Fig. 1, the utility model discloses a kind of High-precision angle locating device, comprise housing 1, capping 2, light activated element 3, charge detection element 4, processor, charge member and generating laser 5; The cylindrical shape of housing 1 in open-top; Light activated element 3 in front inwardly, back side annular outwardly, light activated element 3 is located at the inside of housing 1; Charge detection element 4 ringwise and be close to light activated element 3 the back side arrange; Charge member is located at housing 1 inside and is electrically connected with light activated element 3 and charge detection element 4; Generating laser 5 rotary movable is located in the middle part of housing 1, and generating laser 5 is arranged towards the front of light activated element 3 from housing 1 center; Capping 2 is covered on the top of housing 1; Processor is connected with charge detection element 4.
Prior art, for the location of angle, generally adopts the localization method of optoelectronic switch or pulse step.The installation site of optoelectronic switch is changeless, can only be applied in the occasion of fixed deflection angle; Though pulse step can position control, but the counting of pulse is easier to lose, thus occurs error.For common servomotor, be generally divided into 1000 equal portions by often irising wipe, every equal portions are a deflection unit, every deflection unit angle is 0.36 °, often receive a pulse signal and then rotate 1/1000 circle, thus reach the object controlling deflection angle, precision is higher.The problem that this design existence two is larger: one, pulse signal has certain Loss Rate, and thus deflection angle easily produces error; Its two, the location of angle occurs in controlling unit, and the precision of rotational driving device also likely has impact to deflection angle, and the deflection unit of such as servomotor is greater than or less than 0.36 ° due to error, cause cumulative errors thus.The pivot angle that so now angle positioning device is determined then becomes the theoretical value of an empty talk, becomes meaningless in the occasion that accuracy requirement is high.
And the utility model difference maximum relative to prior art is: the principle adopting optics and electricity to combine carries out High-precision angle location, and the precision of location only depends on the resolution of light activated element 3 and charge detection element 4.And location is not occur in controlling unit, but measure on the spot, therefore the manufacturing accuracy of rotational driving device self does not affect positioning precision.

Electro-conductive glass 6 is conductor, is also light transmissive material simultaneously.The resistivity of photoresistor layer 7 can change along with illumination, and as preferably, described photoresistor layer 7 is uniform selenium packed layer.During use, first by charge member, the photoresistor layer 7 of light activated element 3 and the ring shaped conductor 9 of charge detection element 4 are charged, make the surface of photoresistor layer 7 and ring shaped conductor 9 with electric charge respectively.The ring shaped conductor 9 be now oppositely arranged and photoresistor layer 7 be a composition electric capacity jointly, forms certain electric potential difference between the two.When generating laser 5 rotates, laser can scan photoresistor layer 7.Photoresistor layer 7 is by the conducting because resistivity reduces of the part of laser scanning, thus photoresistor layer 7 is discharged, photoresistor layer 7 and ring shaped conductor 9, connecting electrode form a loop, when connecting electrode has electric charge to flow through, processor can collect electric signal and calculate, thus draws the angle of laser scanning.
As preferably, between described capping 2 and housing 1, be also provided with O-ring seal.The main effect of O-ring seal ensures that housing 1 and capping 2 can not produce gap and light leak, thus form impact to light activated element 3.It also avoid extraneous wet gas on the other hand to enter, and then the normal operation circumstances that impact is inner.
The utility model has two kinds of using method:
The first, rotational driving device is connected with generating laser 5, by rotational driving device active rotation, is gathered by processor by above-mentioned principle and calculate the anglec of rotation of rotational driving device;
Second, rotational driving device is connected with generating laser 5, the angle needing to rotate is precomputed by processor, when after rotational driving device driving laser transmitter 5 synchronous rotary to the angle of specifying, the angle of laser scanning reaches preset value, rotational driving device shuts down, thus carries out the positioning control of specifying the anglec of rotation.
