Background technology
In recent years, the high speed development of the electronic product such as mobile phone, panel computer, has impelled the fast development of glass industry.Glassware in process of production; due to reasons such as uneven, the internal residual stresses of being heated, easily cause the distortion of glass surface, thus after the cover glass of electronic product and screen are fitted; produce larger stress between the two, affect the serviceable life of screen.
Traditional angularity metering system comprises: the modes such as the measurement of manual measurement, catheter type, probe-type measurement.These modes use the mode of manual observation to measure, and measurement result can be subject to the impact that operator self judges, operating personnel are different, and measurement data also can be variant, can not meet the Production requirement of high precision industry.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of automatic glass angularity measuring instrument of high-acruracy survey, being adapted to the angularity high-precision rapid survey of electron trade glassware.
The present invention in order to the technical scheme solving its technical matters and adopt is: the automatic angularity measuring instrument of a kind of face glass, comprise base, high precision laser range finder, for twin shaft guide rail and the fixed mount of fixing high precision laser range finder movement, described twin shaft guide rails assembling is on base, and be made up of horizontal cross guide rail and horizontal longitudinal rail, described high precision laser range finder is arranged on fixed mount, described fixed mount is slidably installed with on horizontal cross guide rail, also be provided with some soft supporting framves and the high level of accuracy glass for correcting, described soft supporting is set up in the below of mother glass, described high level of accuracy glass and mother glass are all located at immediately below high precision laser range finder for detecting.
As a further improvement on the present invention, described high precision laser range finder image-taking device is a USB camera.
As a further improvement on the present invention, be provided with 4 soft supporting framves below described mother glass, described 4 soft supporting framves are located at four angles of mother glass respectively for supporting mother glass.
The invention has the beneficial effects as follows: the present invention drives high precision laser range finder to measure high level of accuracy glass by twin shaft guide rail, calculates the reference range of the measurement point coldest days of the year end; Twin shaft guide rail drives high precision laser range finder measurements to be positioned over glassware on four soft supports, and in conjunction with the reference range of each point, use angularity measure equation, accurately calculates the warp values of this sample; Use nine point-measurement technique, calculated the warp value in sample eight directions by the distance value of sample surfaces 9 respectively.
Whole instrument, by measuring high level of accuracy glass, obtains the measurement baseline of equipment, and baseline is recorded a demerit and participated in the computation process of angularity, greatly reducing the resultant error of instrument, improves the precision of measurement.Use 9 warpage measuring techniques simultaneously, by the measurement result of 9, calculate the warp value in eight directions of sample, substantially increase precision and the accuracy of measurement.
