Part 60 can make light beam change direct of travel；Circuit board 70 can carry laser ruler calibration system 100, and by
It is electrically connected with port 80 to be electrically connected with external device (ED) (not illustrating).
When light emission module 30 object towards the outside launches light beam, can first anti-at luminous reflectance assembly 60
Penetrate and reflect on face, penetrate thereafter lens 50 homed on its target thing；Then, anti-through object when light beam
After penetrating, can first penetrate lens 50 again after luminous reflectance assembly 60 produces reflection, Optical Receivers 40 connect
Receive.
Additionally, body 10 has clamping part 12, supporting part 14 and regulation portion 16.Specifically, light is anti-
Penetrate assembly 60 to be held on body 10 by clamping part 12, and the reflecting surface of luminous reflectance assembly 60 can breasting
On supporting part 14, regulation portion 16 then for regulating the position of luminous reflectance assembly 60, makes luminous reflectance group
Part 60, at the normal direction top offset of reflecting surface, implies that luminous reflectance assembly 60 is along before the normal direction of reflecting surface
/ move afterwards, and then make from object reflection light beam via luminous reflectance assembly 60 produce reflection after, focus in
Optical Receivers 40.Furthermore, owing to have employed luminous reflectance assembly 60 so that the circuit of Optical Receivers 40
Plate (not illustrating) can combine with the circuit board 70 of body 10, and then simplifies laser ruler calibration system
The overall structure of 100.
As in figure 2 it is shown, pedestal 20 includes axis hole 22, accommodation space 24 and counterbore 26.Wherein, light is sent out
Penetrating module 30 to be arranged in counterbore 26, Optical Receivers 40 is arranged in accommodation space 24.
Specifically, the aperture of counterbore 26 is more than the aperture of axis hole 22, therefore, light emission module 30
Curved surfaces can be connected to the seam between axis hole 22 and counterbore 26.Wherein, light emission module 30
Curved surfaces can be circular arc sphere.In the present embodiment, light emission module 30 is by circular arc sphere
So that seam can be tightly fitted in the way of rotating full circular.
Fig. 3 illustrates the equivalent structure schematic diagram of the laser ruler calibration system 100 of Fig. 1.Wherein, anti-due to light
The main function penetrating assembly 60 is to make light beam change direct of travel, therefore, in order to simplify and be easy to explanation,
Luminous reflectance assembly 60 is eliminated in Fig. 3, but not in order to limit the present invention.
Referring concurrently to Fig. 1, Fig. 2 and Fig. 3, counterbore 26 is connected with axis hole 22, and by light emission module
30 launch light beam.Wherein, light beam is after light emission module 30 penetrates, and its direction advanced is i.e. first
Optical axis X1 direction, specifically, if light emission module 30 rotates, then in seam with carrying out full circular
The direct of travel of light beam can be changed, imply that the direction changing primary optic axis X1.In other words, can be by rotation
Light emission module 30 and change the direction of primary optic axis X1；Accommodation space 24 be then arranged on by lens 50,
On the second optical axis X2 that luminous reflectance assembly 60 and Optical Receivers 40 are constituted.In short, be arranged at heavy
The light emission module 30 in hole 26 is also equal to be arranged on primary optic axis X1 simultaneously, and is arranged at accommodating sky
Between 24 Optical Receivers 40 be then provided on the second optical axis X2.
On the other hand, can be connected to rotatably by full circular by its circular arc sphere due to light emission module 30
Interface, thus when the direction of primary optic axis X1 changes, the second optical axis X2 also can interlock therewith.This means,
When light emission module 30 rotates, the direction (that is, the direction of primary optic axis X1) that light beam is advanced can be changed,
And then make the direct of travel (that is, the direction of the second optical axis X2) of the light beam from object reflection change.
In an embodiment, light emission module 30 includes light emission component, and wherein light emission component can use
Laser luminescence diode；Optical Receivers 40 includes light-receiving assembly, and wherein light-receiving assembly can use and collapse
Routed optical diode；Lens 50 can be to receive big eyeglass；Luminous reflectance assembly 60 includes light reflection mirror；And light is sent out
Penetrate light beam that module 30 launched and the light beam that Optical Receivers 40 is received can be then laser light.
Fig. 4 illustrates the flow chart of the light path calibration steps of one embodiment of the invention.Must first illustrate, figure
Light path calibration steps disclosed in 4 can be applicable to the laser ruler calibration system 100 of Fig. 1, so the most only
Calibrate system 100 with the laser ruler disclosed in Fig. 1 to explain, but not in order to limit the present invention.
Referring concurrently to Fig. 1, Fig. 2 and Fig. 4, the light emission module 30 of laser ruler calibration system 100 is positioned at the
On one optical axis X1, Optical Receivers 40 and lens 50 are then positioned on the second optical axis X2, during calibration, and palpus
Make primary optic axis X1 and the second optical axis X2 parallel to each other, and make the dot projection of light beam in light-receiving mould
In the preset range of block 40, so that Optical Receivers 40 receives the strongest light energy.
In step S210, light emission module 30 is utilized to launch light beam.Thereby, by light emission module 30
The light beam homed on its target thing sent, and after object reflects, penetrate lens 50, thereafter at luminous reflectance
Reflection is produced on the reflecting surface of assembly 60.
In step S220, coarse adjustment light emission module 30.In this step, adjust light by full circular
Transmitter module 30 changes the transmitting angle of light beam, makes the direction of primary optic axis X1 change, and related makes second
The direction of optical axis X2 changes, and is perforated through lens 50 and through luminous reflectance group with order from the light beam of object reflection
After part 60 reflection, it is projeced into Optical Receivers 40.
Specifically, light emission module 30 sustainable development irradiating light beam.Further, object the light beam reflected
Lens 50 can be penetrated, and change light conduct direction via luminous reflectance assembly 60.Now, via luminous reflectance group
The light beam of part 60 reflection may not necessarily be incident upon on Optical Receivers 40 accurately, but can be by the mode of coarse adjustment
Adjusting light emission module 30, e.g. full circular ground rotates light emission module 30, to change primary optic axis X1
Direction, simultaneously, the direction of the second optical axis X2 the most synchronously changes.Thereby, can allow from target
The light beam of thing reflection converges on Optical Receivers 40.
In step S230, finely tune luminous reflectance assembly 60.In this step, when determining that light beam can converge at
After on Optical Receivers 40, i.e. can adjust luminous reflectance assembly 60, make luminous reflectance group in the way of fine setting
Part 60 is front/rear displacement in the normal direction of reflecting surface, produces reflection to light beam through luminous reflectance assembly 60
After, can focus in Optical Receivers 40, make the dot projection of light beam in the preset range of Optical Receivers 40
In, so that Optical Receivers 40 receives the strongest light energy.Specifically, fine setting luminous reflectance assembly 60
Can be via the regulation portion 16 adjusted on body 10 so that luminous reflectance assembly 60 is in the normal of reflecting surface
Front/rear displacement on direction.
In sum, although the present invention is disclosed above with embodiment, but it is not limited to the present invention.
Those skilled in the art, without departing from the spirit and scope of the present invention, when making various changes and profit
Decorations.Therefore, protection scope of the present invention is when being as the criterion depending on as defined in claim.
