Description
Technical field
The utility model relates to a kind of automation equipment, in particular to a kind of automobile bend glass laser detects automatically to be set
It is standby.
Background technique
Detection of the tradition for automobile bend glass is that multiple test points are preset on glass curve, by multiple inspections
The DATA REASONING of difference in height between measuring point and glass highest point (or minimum point), substantially to determine whether glass curve is qualified
Part is only carried out in a manner of sampling observation mostly, and whole detections can not be carried out to bend glass, and detection method falls behind, measurement effect
Rate is low, and a detection is taken to be easy to cause the missing inspection of defective products.
Vehicle glass generally is transparent curve form, and light source is radiated on transparent glass and is easy to appear total reflection now
As laser detection is to realize its function by the reflection of light source, if laser largely transmission or total reflection, causes anti-
The luminous flux for being emitted back towards laser head is reduced, and laser head will be unable to detect accurate result.Therefore, it to improve and transparent glass laser is examined
If surveying precision, it is necessary to form one layer of reflecting layer, on the glass surface of detection for reducing the transmitted light and increase glass of glass
The diffusing reflection of glass improves the precision of laser detection, if forming film by spraying the modes such as dust on glass, that certainly will be wanted
Increase the process to bend glass dust film cleaning,.The phenomenon and glass encountered in our daily lifes hazes, principle
Be: when ambient temperature is higher, water vapour saturated pressure is big, and glass temperature is low, and the saturated pressure of steam reduces near glass, when
The temperature difference is sufficiently large, and when saturated pressure is sufficiently low, water vapour just liquefies, and forms aerosol.Saturated pressure closer to bath of glass is got over
It is low, the easier aerosol liquefaction of water.Hydrone in air is ceaselessly doing erratic motion, and when not having the temperature difference, hydrone is not
Stop getting on glass, and does not stop to fly out from glass and.Because temperature more harmonic motion rate is slower, sky of the hydrone from heat
It after gas is got on cold glass, moves slack-off, cannot fly out and in time, and the hydrone of outside is also ceaselessly toward on glass
It beats, so the water on glass is more and more, is just gathered into droplet.
