Description
Technical field
It is related to sensor field, and in particular to sensor, industrial robot, robot.
Technical background
Existing sensor, with high costs, cost very high to requirement on machining accuracy is very high, complex structure, more sensitive biography
Sensor, the small environmental change of easier sensing, detecting system is more sensitive more is conducive to the high speed of equipment to react, existing Gao Min
The sensor price of sensitivity is very expensive.
The content of the invention
The present invention relates to sensor, industrial robot, robot, using the teaching of the invention it is possible to provide a kind of Sensor Design new approaches.
1st, sensor, it is characterised in that：Including the first photo resistance (R1), the second photo resistance (R2), operational amplifier
(U1:A), power supply point (VCC), negative supply (- VCC), place (GND), reference source (Vref), output point (OUT)；
The first end of the first photo resistance (R1) is connected with reference source (Vref)；
Second end of the first photo resistance (R1) and operational amplifier (U1:A end of oppisite phase) is connected；
The first end of the second photo resistance (R2) and operational amplifier (U1:A end of oppisite phase) is connected；
Second end of the second photo resistance (R2) and operational amplifier (U1:A output end) is connected；
Operational amplifier (U1:A in-phase input end) is connected with place (GND)；
Power supply point (VCC) and operational amplifier (U1:A positive power source terminal) is connected；
Negative supply (- VCC) and operational amplifier (U1:A negative power end) is connected；
First photo resistance (R1), the entity of the second photo resistance (R2) are set up in parallel, the first photo resistance (R1), second
Photo resistance (R2) is while receive the same hot spot of laser (S9).
Industrial robot, robot, with foregoing sensor.
Technology contents are illustrated, and its advantage.
Because the first photo resistance (R1), the second photo resistance (R2) receive same hot spot, when hot spot is moved, so first
Photo resistance (R1), the second photo resistance (R2) change in the opposite direction, and add the first photo resistance (R1), the second photo resistance
(R2) different reference modes in circuit；So that the first photo resistance (R1) change in resistance trend and exporting change trend
Association, the second photo resistance (R2) change in resistance trend are associated with exporting change trend, and the two is conversely, one is positive correlation one
Individual negative correlation；The present invention can play a part of drastically to amplify, the movement for measuring hot spot that can be apparent, can detect shadow
Ring the physical quantity of hot spot movement, such as the motion of refractive index, speculum, the motion of light source.
The position movement of the hot spot that the present invention can be sent by laser (S9) produces larger electricity difference in change, this hair
Bright design architecture allows the invention to amplify difference in change, improves photosensitive susceptibility, reduces manufacturing cost, can be also used for inspection
Survey vibrations.
Simple structure of the present invention, with low cost, susceptibility is high, be easily worked, there is provided a Sensor Design new approaches.
Brief description of the drawings

Show the intensity level-magnitude of voltage of circuit output.
Fig. 2 is the structural representation of embodiments of the invention 2.
Drawing reference numeral explanation：First photo resistance (R1)；Second photo resistance (R2)；Number one integrated circuit (U1).R1、
R2, U1 collectively form proportional amplifier, the amplification ratio of R1, R2 change influence proportional amplifier, therefore exporting change.Vref is perseverance
Pressure reference source.Vout=Vref* (- R2/R1), the slight movement of hot spot can all cause the drastically change of output signal, so quick
Sensitivity is very high.
