Description

Marking device for glass stress testing

technical field

The utility model belongs to the technical field of glass testing, in particular to a marking device for glass stress testing.

Background technique

For the stress birefringence test of optical materials such as optical glass, especially large-sized glass, it is necessary to draw a corresponding test mark before the test to identify the point of the upcoming stress birefringence test; for example, colorless optical glass The national standard for stress birefringence testing stipulates that the maximum stress at a position 5% away from the edge of the sample should be tested as the final test result. At present, for rectangular or quasi-rectangular glass samples, the distance between the opposite sides is usually measured with a plate ruler or tape measure, and then 5% of the distance is calculated as the marking distance, and then the plate ruler or tape measure is used to measure the distance from the edge of the sample to the line. Measure the distance of the previously calculated marking line inside the sample, and start to use a marker pen to continuously draw a line along the edge of the glass sample on its surface. This line is the test marking line for the stress test of the sample; Multiple dimensional measurements and calculations are error-prone and inefficient, especially for stress testing of large batches of samples.
