Abstract
The invention discloses a device and a method for detecting the thickness of hollow glass and the width of an aluminum frame. The device comprises a frame body, a laser emitting source, a CCD (Charge Coupled Device) image sensor and a computer. The method comprises the following steps: a. the laser emitting source and the CCD image sensor are arranged on the parallel surfaces of the detected hollow glass; b. laser emitted from the laser emitting source enters the detected hollow glass and after being reflected and refracted a plurality of times by the detected hollow glass, the light ray reaches the CCD image sensor to form displacement difference, and the displacement difference is converted into a digital signal; and c. the computer is used for calculating the thickness value of the detected hollow glass and the width value of the aluminum frame through an optical formula according to the digital signal of the displacement difference. The invention has the advantages that: the step of modifying parameters again after the specification of the glass is changed is omitted, therefore, the detection efficiency is improved; and the failure of normal gluing or machine damage caused when parameters are forgot to be changed is avoided, therefore, the safety and the stability of the detection are improved.

Computing machine, the digital signal of utilizing ccd image sensor to convert to calculate the numerical value of tested double glazing thickness and aluminium width of frame.
Above-mentioned support body is positioned at tested double glazing top, the convenient detection.
The detection method of double glazing thickness of the present invention and aluminium width of frame pick-up unit may further comprise the steps:
A., laser emitting source and ccd image sensor are set on the parallel surface of tested double glazing;
B. the laser emitting source emitted laser is injected tested double glazing, and the light after tested double glazing reflection and refraction several times drops on and forms displacement difference on the ccd image sensor and convert digital signal to;
C. utilize the optics formula to calculate the numerical value of tested double glazing thickness and aluminium width of frame according to the digital signal of displacement difference by computing machine.
The detection method of above-mentioned double glazing thickness and aluminium width of frame pick-up unit comprises: the tested double glazing upper surface in upper strata is reflected in first reflection spot on the ccd image sensor; Enter refracted ray in the tested double glazing in upper strata and drop on second refraction point on the ccd image sensor through the lower surface reflection and after the upper surface refraction; Reflect the tested double glazing light in upper strata at the third reflect point that drops on after the tested double glazing upper surface reflection of lower floor and after the tested double glazing refraction in upper strata on the ccd image sensor; Enter refracted ray in the tested double glazing of lower floor through the lower surface reflection after drop on fourth reflect point on the ccd image sensor after the tested double glazing refraction in lower floor and upper strata; Displacement difference described in step b and the step c is the displacement difference between first reflection spot, second refraction point, third reflect point and the fourth reflect point.
The incident angle of laser can be saved the length of ccd image sensor less than 45 ° among the above-mentioned steps b.
Laser emitting source sends red visible laser bundle among the above-mentioned steps b, is convenient to observe.
The invention has the beneficial effects as follows: omitted after changing, revised the step of parameter once more, improved detection efficiency when glass size.Avoided because forget the modification parameter, normally gluing or the physical damage that cause have improved the security and the stability that detect.Operate fairly simple and be difficult for makeing mistakes, only need glass before thickness measuring system, to suspend and to read parameters automatically for a moment.
