Specific embodiment
Example embodiment is described more fully with reference to the drawings.However, example embodiment can be with a variety of shapes
Formula is implemented, and is not understood as limited to example set forth herein；On the contrary, thesing embodiments are provided so that the disclosure will more
Fully and completely, and by the design of example embodiment comprehensively it is communicated to those skilled in the art.Described feature, knot
Structure or characteristic can be incorporated in any suitable manner in one or more embodiments.
A kind of galvanometer motor is provided firstly in this example embodiment, referring to figs. 1 to Fig. 3, which includes watching
Take motor 10 and refractor 20.The refractor 20 includes the plane of incidence 21 and exit facet 22, which receives
One has the incident beam 50 of default incidence angle a, and forms deflecting light beams 51 by unirefringence, which goes out at this
It penetrates face 22 and forms outgoing beam 52 after birefringence and be radiated on the predetermined position of working face 60.The output shaft of the motor 10
The 11 connection refractors 20, to drive the refractor 20 to deflect and change the incidence angle a adjust it is described go out
Displacement of the irradiating light beam 52 on working face 60 is to form preset pattern.
In the present embodiment, as shown in figure 3, the refractor 20 have preset lens thickness t, lens thickness t with
Displacement of the outgoing beam 51 on working face 60 is related, in the application, it is thick can to control the eyeglass according to actual needs
Spend t.The refractor 20 has preset refractive index, and the refractive index is related to the material of the refractor 20, usually
In the case of, different refractor materials possesses different refractive index, and refractive index is higher, the ability for reflecting incident beam
It is stronger.
In one embodiment, referring to shown in Fig. 3, in order to enable being more likely to more light beams passes through refractor 20, it is described
Refractor 20 is made of transparent material, which can select the materials such as glass, resin or crystal.The present embodiment
In, at least one in the plane of incidence 21 and exit facet 22 of refractor 20 is coated with anti-reflection film, and the effect of anti-reflection film is to reduce reflection
The intensity of light, to increase the intensity of transmitted light.Common anti-reflection membrane material have magnesium fluoride, titanium oxide, vulcanized lead, lead selenide with
And ceramic infrared light infrared anti-reflection film, vinyl silsesquioxane hybridized film etc., the invention is not limited in this regard.
As shown in Fig. 2, in one embodiment, the galvanometer motor further includes a bracket 30, the refractor 20 is logical
Bracket 30 is crossed to connect with the output shaft 11 of the motor 10.The refractor 20 is fixed on the bracket 30, the bracket 30
It is connected on the output shaft 11 of the motor by fastener 40.In practical applications, often because the difference of demand, will replace
Different size, different types of refractor 20, the bracket 30 and refractor 20 are detachable for operating easily,.?
In the present embodiment, refractor 20 is bonded in one end of the bracket 30, and the other end of the bracket 30 is fixed by screws in
On the output shaft 11 of motor 10.The quantity of fastener 40 is more than or equal to 1 in the present invention, as long as guaranteeing that the bracket 30 can the company of consolidating
It connects on the output shaft 11 of motor 10, for example, the quantity of the fastener 40 is 2 in the schematic diagram of Fig. 2.
This example embodiment additionally provides a kind of laser galvanometer, including at least one is as described in any of the above-described embodiment
Galvanometer motor, in the present embodiment, the incident beam 50 that the refractor 20 of the galvanometer motor is received be laser beam,
The laser beam is issued by laser emitter.
Referring to figs. 1 to Fig. 3, the laser galvanometer controls watching for the galvanometer motor during the work time, using driving plate
Motor 10 is taken, by the rotation of output shaft 11 on servo motor 10, the refractor 20 is driven to be rotated.When the refraction
When eyeglass 20 turns an angle, incidence angle a just changes an angle, correspondingly, the angle of the refraction angle b of deflecting light beams 51 is sent out
Changing, so that the position that outgoing beam 52 is penetrated on working face 60 also changes, to scan the figure that we want.
In one embodiment, the horizontal plane of incidence 21 for injecting refractor 20 from air of incident beam 50 forms incidence
Angle a forms the deflecting light beams 51 with refraction angle b after unirefringence occurs, and the deflecting light beams 51 are in exit facet 22 through secondary
After refraction, forming the amount of side-shift that outgoing beam 52 is radiated on working face 60 is X.Assuming that the lens thickness of the refractor 20 is
The refractive index of t, eyeglass are k, then are obtained according to the law of refraction：
Sin a/sin b=k (when light beam injects medium by air, k > 1)
X=t sin (a-b)/cos b
In the prior art, as shown in figure 4, being reflected when the horizontal injection reflex reflector lens 70 of incident beam 50, it is assumed that enter
The angle of reflection of irradiating light beam 50 be c, incident beam 50 with working face 60 at a distance from be A, then incident beam 50 through reflection after
Horizontal distance on working face 60 is Y, then：
Y=Acot2c
When the incident direction of incident beam 50 is constant, and since error causes the motor output shaft 11 of galvanometer motor to deflect
Angle ω drives eyeglass also to produce a deflection angle ω, if the eyeglass is the refractor 20, it is assumed that incident beam 50
Refractive deflection angle be ω1If the eyeglass is reflecting optics 70 in the prior art, it is assumed that the reflection of incident beam 50 deflects
Angle is ω2, then：
sin(b-ω1)-sin b=sin (a- ω)/k-sin a/k
When a level off to 0 when, sin a level off to 0, sin b level off to 0 above formula can abbreviation be：
sin(b-ω1)=sin (a- ω)/k
sin b cosω1-cosbsinω1=(sin a cos ω-cos a sin ω)/k
Then sin ω1=cosa sin ω/k cosb
Due to cosine function in 0-90 ° of section monotone decreasing
B < a again
So cosb > cosa
K > 1 again
So sin ω1< sin ω
Due to SIN function in 0-90 ° of section monotonic increase
So ω1< ω
And ω when reflecting2=2 ω
So ω22 ω of >1
It can be seen that in conjunction with above-mentioned formula, when the error that motor deflects is identical, galvanometer motor provided by the present invention
Deflecting light beams deflection angle will than in the prior art reflecting optics generate small one times of reflected light deflection angle or more, to reduce
The location error that the outgoing beam is formed on working face, and then the precision of galvanometer motor is improved, also reduce interference
