Description
Technical field
The present invention relates to a kind of detection device, especially relate to a kind of whether detect laser bias in laser optical path
Device.
Background technology
At present, carry out in the equipment such as laser printing, cut at various utilization high power lasers, laser optical path
It it is the key being related to make full use of laser power.The adjustment of general laser optical path is in rigging up and debugging
Time, send the trend of HONGGUANG simulated light with a visible ray diode, carry out light path adjustment.Due to light emitting diode with
There is the inconsistence problems such as installation site, size, beam size in actual laser instrument.Laser instrument is caused to make actual
Used time, cause the unnecessary loss of laser power.
Chinese patent CN 102564298 A discloses and a kind of detects what whether laser in high power laser light light path was partial to
Method, comprises the steps: step 1: choose a diaphragm, and there is a light hole centre of this diaphragm；Step 2:
A circle thermistor wire it is fitted around around the light hole of diaphragm；Step 3: this diaphragm is placed in predetermined
In the light path of optical direction；Wherein when laser is without departing from predetermined direction, energy can be completely by the light hole of diaphragm
Time, resistance wire will not generate heat；Wherein when laser deviation predetermined direction, the laser of deviation can cause by resistive heater
The change of its resistance, thus obtain alarm signal.Owing to resistance wire is very thin, and resistance wire is positioned at a vertical plane,
When laser optical path slightly has deviation, laser is it is also possible that thermistor wire, now critesistor will not be touched
Silk will not generate heat, i.e. there is no alarm signal, but now laser is but biased into, therefore, and the inspection of this invention
Survey accuracy is poor.On the other hand the circle that thermistor wire surrounds is relatively large in diameter, and diameter is the biggest, and laser beam is more
Being not easy to touch thermistor wire, the error i.e. detected is the biggest.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and provide a kind of structure letter to answer,
Laser bias whether device in the detection laser optical path that accuracy of detection is high, easy to use.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of device whether detecting laser bias in laser optical path, is arranged on the laser beam in laser optical path,
This device includes induction tube, temperature sensor and support, and described temperature sensor is arranged on induction tube, described
Induction tube be arranged on support；Described induction tube offers the tube chamber passed through so that laser beam vertically；Institute
The induction tube stated is made up of thermo-sensitive material.
Preferably, a length of the 10 of described induction tube～20mm, the internal diameter of induction tube is more straight than laser beam
Within the big 1mm in footpath.
Preferably, the tube chamber of described induction tube is cylindrical.
Preferably, described support is fixed on induction tube and enters the entrance point of laser beam or go out the outlet of laser beam
End.
Preferably, described support is telescoping shoring column.
Preferably, the lower end of described support is provided with the fixing groove of installation.
The present invention is based on laser aid when Laser emission, if laser optical path is normal, laser beam directly passes through
The tube chamber of induction tube, is not radiated on induction tube tube wall, thus does not results in the temperature sensor being connected with induction tube
Temperature raises, and once laser aid is occurred owing to fixed device for laser affects generation laser optical path by external vibration
During deviation, laser beam can be mapped on induction tube tube wall, thus causes induction tube surface temperature to rise, temperature sensing
Device temperature sensor changes, and outwards output signal.
Compared with prior art, the present invention has the following advantages and beneficial effect:
(1) assembly of the invention simple in construction, it is easy to manufacture, and by arranging temperature sensor, use in real time
Temperature detection, therefore, just can obtain information once the laser beam generation deviation in laser optical path, adjust in time
Whole, it is ensured that laser power is fully utilized.
(2) present invention uses whether induction tube senses the deviation of laser beam, owing to induction tube has necessarily
Length, therefore, higher for beam deviation whether detection degree of accuracy；
(3), in the present invention within the internal diameter of induction tube 1mm bigger than the diameter of laser beam, laser beam is slightly
Deflection just can be detected immediately upon, and improves the degree of accuracy of detection further.
(4) can arrange support is telescoping shoring column, in order to adjust its height, easy to use.
(5) lower end at support is provided with the fixing groove of installation, can be fixed in certain bits when life-time service
Put, its position need not be adjusted every time, improve detection efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is that zero deflection laser beam is by apparatus of the present invention schematic diagram；
Fig. 3 is that the laser beam that deviation occurs is by apparatus of the present invention schematic diagram.
