Specific embodiment
A kind of dental handpiece dynamic Laser focusing system as Figure 1-3, in figure：Mobile phone 1, condenser lens (3, M1),
Collimation lens (4, M2), focus lamp (5, M3), displacement drive 2, range sensor 6, control system 10.
A kind of dental handpiece dynamic Laser focusing system is provided, as Figure 1-3, it includes：Mobile phone 1, condenser lens 3,
Collimation lens 4, focus lamp 5, displacement drive 2, range sensor 6, control system 10；The inside of mobile phone 1 arranges condenser lens
3rd, collimation lens 4, focus lamp 5, displacement drive 2, range sensor 6 is placed in mobile phone top and electric with control system 10
Connection, displacement drive 2 is connected with condenser lens 3, and displacement drive 2 is electrically connected with control system 10.
Range sensor 6, displacement drive 2 collectively form dynamic focusing feedback control system with control system 10.
Inside mobile phone 1, condenser lens 3, collimation lens 4, focus lamp 5, displacement drive 2 collectively form dynamic focusing drive system.
A kind of dental handpiece dynamic Laser focusing system is provided, wherein condenser lens 3 is connected on displacement drive 2,
Displacement drive 2 can adopt piezo-electric crystal, piezo-electric crystal to produce stroke by voltage signal control, control condenser lens 3
Movement.
Electric machine structure is not adopted to be that piezo-electric crystal small volume, Bit andits control is simple, and structure can using piezo-electric crystal
Lean on, its deficiency is that Bit andits control amount is little, but fit into the internal structure feature in mobile phone small volume.
Range sensor 6 is placed in mobile phone top, and in real time measurement mobile phone and the distance in treatment face, feed back to control system,
Adjustment piezo-electric crystal signal, controls the distance of condenser lens 3, so as to realize the control of dynamic focusing.
A kind of dental handpiece dynamic Laser focusing system is provided, control system 10 can be located inside mobile phone 1, it is also possible to
It is arranged at outside mobile phone 1；Control system is electrically connected by cable with range sensor 6 and displacement drive 2, or by nothing
Line transmission means is connected with range sensor 6 and displacement drive 2.
Range sensor 6 can be laser distance sensor, ultrasonic distance sensor, electric capacity or inductance type sensing
Device, by distance signal transmission to control system, control system can be the intelligent controllers such as computer, single-chip microcomputer, PLC, control
Device can preset the dynamic focusing distance for needing control, and according to the distance of actual measurement, output adjustment signal is to piezo crystals
Body drive control, adjusting focal length is integrally formed closed loop feedback control.
In the use of dentistry laser handpiece, sometimes for fine treatment, need Laser Focusing in affected part, due to mobile phone
It is manual hand manipulation, it is difficult to the accurate distance in stable mobile phone and affected part, therefore be also difficult to ensure to swash in actual application
Optical focus acts on affected part.Therefore application of the dynamic focusing on dental handpiece just becomes critically important, and doctor in operation only needs
Treatment affected part is probably directed at, and focusing work is automatically performed by mobile phone, during operation is mobile, be always ensured that laser is burnt
Point alignment affected part, reaches the purpose of accurate treatment.
As shown in figure 3, the operation principle of dental handpiece dynamic Laser focusing system is as follows：
Dynamic focusing lens (M1) are the motions for having added a Z-direction on conventional focusing lens.It is different with scan position,
Dynamic focusing lens (M1) are moved forward and backward, so as to ensure the accurate focusing on scanning plane.The motion of dynamic focusing mirror is by position
Move driving means to realize, it is capable of achieving bidirectional-movement.
Due to limited space in dentistry laser handpiece, condenser lens displacement is short, it is therefore desirable to which feed rod linkage is adding
Big stroke.
Wherein, variation delta s of focal position with the movement of condenser lens away from z monotonically increasings.
The beneficial effects of the utility model are as follows：
A kind of dental handpiece dynamic Laser focusing system of the utility model design, realizes dynamic focusing control, Neng Goubao
Accurate focusing of the card laser on scanning plane.In practical operation, doctor only needs to probably alignment treatment affected part, automatic by mobile phone
