Glass fragment gathering device for automotive glass impact resistance experiment and method thereof

Abstract

The invention discloses a glass fragment gathering device for an automotive glass impact resistance experiment and a method thereof. The device comprises a sample supporting part and a glass fragment gathering part which comprises a funnel, a replaceable catch plate positioned below the funnel and a conveyor track used for placing the catch plate. The method comprises the following steps: placing a sample; carrying out an impact experiment; gathering and conveying fragment sample; taking out waste sample; placing a new sample, and conveying the new catch plate below the funnel. By the above technical scheme, fragment gathering can be guaranteed to be complete, and test data can be guaranteed to be accurate; efficiency of the impact resistance experiment can be effectively enhanced; and the operation of replacing the catch plate on the conveyor track can be completed at the outer side of the sample supporting part, and the operation is relatively simple.

Description

technical field [0001] The invention relates to the technical field of glass industry, in particular to a device and method for collecting glass shards in an impact resistance test of automobile glass. Background technique [0002] With the improvement of people's living standards and the application of advanced manufacturing technology, private cars have gradually become the preferred means of transportation for travel. As an important part of a car, the safety performance requirements of auto glass are always given top priority. [0003] In the current national standard "Automotive Safety Glass" (GB 9656-2003) and "Automotive Safety Glass Test Methods Part 1: Mechanical Properties Test" (GB 5137.1-2002), in the impact resistance test of automobile laminated glass, it is required to say Take the total mass of the fragments peeled off from the opposite side of the impact surface and the mass of the largest fragment. Laminated glass is two layers of glass overlapped with a ...

AI Technical Summary

Problems solved by technology

The above-mentioned glass shard collection device in the prior art has the defect that it cannot accurately collect the detached glass shards: if an independent collection tray is used to be placed inside the support frame 6 in a manner that fits on the inner side wall of the support frame 6 On the lower side, the glass shards that have peeled off can fall into the collection tray completely, but it is difficult to manufacture a collection tray that is consistent with the size of the support frame 6 and is easy to take out and put in.

so use figure 1 The method in this method: the front windshield glass of the car is ordinary laminated glass, and the glass fragments peeled off when the glass is impacted fall on the rubber collection film 3, and when the damaged sample glass is removed from the support frame, there will still be part of the glass Fragments are detached from the rubber collection film 3, thereby increasing the peeling amount of the glass, making it difficult to ensure the objectivity and authenticity of the weighing results; at the same time, the process of taking out and putting in the collection film or the like is cumbersome and is all done manually, which seriously affects the experiment work efficiency
