Glass fragment state detection device

Abstract

The invention discloses a glass fragment state detection device, comprising a fixed barrier strip and a movable barrier strip for fixing a glass sample and a support baseplate for placing and supporting glass, wherein the fixed barrier strip is composed of a transverse support strip and a longitudinal support strip, and is 7-shaped; the movable barrier strip is L-shaped, and is arranged on the fixed barrier strip, tow ends of the movable barrier strip are respectively and correspondingly connected with any section of the transverse support strip and the longitudinal support strip of the fixed barrier strip in a clamping manner, and the movable barrier strip and the fixed barrier strip form a closed rectangular frame matched with the glass sample to be tested; an image acquisition device and an image processing device electrically connected with the image acquisition device are arranged above the rectangular frame fixing the glass sample; the support baseplate is arranged at the inner side of the fixed barrier strip, and the upper end of the support baseplate contacts with the lower end of the movable barrier strip. The glass fragment state detection device disclosed by the invention has the advantages of simple structure, quick detection and accuracy.

Description

technical field [0001] The invention belongs to the field of glass quality detection, and in particular relates to a glass fixing experimental device and a glass fragment detection system for performing fragmentation experiments after the glass to be measured is fixed. Background technique [0002] Generally, after the tempered glass is made, in order to ensure the quality of the tempered glass, a fragment test is usually carried out on samples to check the number, size and shape of the fragments within a certain size. In the specified area, the number of fragments within any 50*50mm should be greater than or equal to 30. After the tempered glass with a thickness of 4mm to 12mm is broken, the number of fragments within any 50*50mm should be greater than or equal to 40 in the specified area, and a small amount of long strips are allowed. Fragments, the length of which does not exceed 75mm. After the inspection is completed, the inspector will judge whether the quality of the...

However, the fixing methods of the existing glass samples are all fixed by enclosing them with four stoppers. As announced by the State Intellectual Property Office of China on January 7, 2015, the announcement number is 204086008 in a state of fragmented tempered glass. experimental device

Although the movable retaining wall and the fixed retaining wall of the experimental device can be adjusted according to the size of the glass sample, one of the movable retaining walls is suspended and there is a gap between it and the glass sample. However, the fixing structure of the baffle is not strong enough, and the fixing is troublesome

In addition, after the experiment is completed, the above-mentioned fixed retaining wall and movable retaining wall need to be removed, and then the glass fragments on the bottom plate should be poured into the garbage. However, this processing method is too troublesome, time-consuming and labor-intensive
