Method for detecting glass by disc wheel rotary table rack image pick-up step press plate

Abstract

The invention relates to a toughened glass test inspection method, in particular to a method for detecting glass by a disc wheel rotary table rack image pick-up step press plate. Through improvement, the toughened glass fragment test comprises the following steps that 1, a disc wheel crank handle is anticlockwise rotated, and a test table plate is in a horizontal state; 2, a press plate fixing plate, a press plate right side, a press plate opposite side and a press plate left side with the same structures are put on the test table plate to surround an ambient surrounding space; 3, the toughened glass to be tested is put on the test table plate in the ambient surrounding space, so that a rubber press sheet on each press plate is attached to the outer edges of the four sides of the toughened glass to be tested; 4, when the conical tip of an impact hammer is downward moved to the lowest position, the toughened glass is crushed through impacting; 5, an image-pickup motor is started; image-pickup shooting is performed; a fragment image is transmitted to a computer processing center; whether the crushed toughened glass is qualified or not is judged according to national standard requirements; the fragment state test of the toughened glass is completed.

Description

technical field [0001] The invention relates to a test and inspection method for tempered glass, in particular to a method for inspecting glass by using a test and inspection method equipped with an industrial camera instead of manual operation and using a pan-lun turntable rack camera to take pictures of a stepped pressure plate. Background technique [0002] Fragmentation state test is one of the contents of mechanical performance inspection, the purpose of the test is to evaluate the possibility of injury caused by fragments when the safety glass is broken. my country is the same as Japan and the European Community in terms of safety glass testing methods and results. In the process of fragment state inspection, it is necessary to record the number, shape and size of fragments within a 50mm×50mm square that meet the requirements after the sample glass is broken. Due to the irregular shape and large number of fragments produced after glass breaking, manual methods are cu...

Problems solved by technology

This method is not only inconvenient to operate, it takes a long time, and the tape is a disposable product, which is easy to cause waste and pollution, and the tape residue on the test bench must be removed after each test to remove the broken glass, otherwise , the remaining glass fragments will affect the next experimental test operation

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

[0005] 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
