Method for detecting glass by meas of handled table, screws and camera wheel corner clamps

Abstract

The invention relates to an armored glass testing method, in particular to a method for detecting glass by means of a handled table, screws and camera wheel corner clamps.As improved, armored glass fragment test includes steps of (1), fastening a test table in a horizontal state; (2) arranging four clamps which are of the same structures and dimensions on the test table; (3) closely attaching rubber press pieces of each clamp onto four edges of a to-be-tested trapezoidal glass sheet; (4), breaking the trapezoidal glass sheet; (5) taking pictures by cameras and sending the pictures of fragments to a computer processing center, and then determining whether the broken trapezoidal glass sheet is qualified or not according to national standards; (6) clearing the fragments of the armored glass and collecting the same in a glass fragment collector through a glass fragment guide; and (7), downwardly griping a handle of the table again with hands to reset the test table in the horizontal state again.During test, cylinder impactors are applied to guarantee uniform hamming each time so as to guarantee normal and unified breakage test.

Description

technical field [0001] The invention relates to a test and inspection method for tempered glass, in particular to a test and inspection device equipped with an industrial camera instead of manual operation, which uses a handle, platen, screw, camera, wheel, and angle fixture to detect glass. Background technique [0002] G0rd0nGaileG published the article "Aut0matedGlassFragmentati0nAnalysis" in 1996, discussing the detection algorithm of glass fragments. This document involves two key technologies: (1) image acquisition technology. Under a piece of photosensitive paper imaged by glass shards, light sources were applied from two different angles, and an original digital image of the shadow of the crack line of the shards was collected. In this way, due to the use of light sources at different angles, the two images collected must be different. In one of the images, the position of the inconspicuous seam line due to lighting may be more obvious in the other image. Therefo...

Problems solved by technology

Chinese patent application number: 2009203050079, tempered glass falling ball test bench, in order to solve the problem of glass fragments splashing everywhere when tempered glass is used for experiments, the method of supporting the frame box is adopted. Although the glass fragments can be collected effectively, it is inconvenient to read the glass fragments. , and the installation efficiency of continuous multi-piece tempered glass is low

Due to the diversity of automobile designs, the glass on the corresponding car is becoming more and more complex. The shape of the glass is often not square or rectangular, but parallelogram or trapezoidal. Uniform fixing fixtures can only use scotch tape paper or other methods to constrain the periphery of the glass, or cover a layer of film on the tempered glass to prevent glass fragments from splashing

At the same time, the adhesive tape is also likely to be broken by the force of the tempered glass explosion, causing the operator to be injured. Therefore, it is very necessary to improve the tempered glass fragment test device
