Abstract

The invention provides a tensile test tool. The tensile test tool comprises an upper mould, a lower mould, and a positioning pin. The bottom of the upper mould is provided with an upper installation position, which is used to install an upper screw. The bottom of the upper mould is also provided with an upper positioning hole. The top of the lower mould is provided with a lower installation position, which is used to install a low screw. The top of the lower mould is also provided with a lower positioning hole. The upper installation position is opposite to the lower installation position. The upper positioning hole is opposite to the lower positioning hole. The positioning pine is used to insert into the upper positioning pin and the lower positioning pin at the same time to positioning the upper mould and the lower mould so as to align the upper installation position and the lower installation position. The tensile test tool can accurately align the upper screw and low screw, the test error is reduced, the actual sealant binding performance of liquid crystal box can be accurately evaluated to obtain accurate test results, the disqualified products can be improved in time, and the improvement cost is reduced.

Description

technical field [0001] The invention relates to the technical field of test fixtures, in particular to a tension test fixture. Background technique [0002] When evaluating the bonding ability between the color filter substrate (CF) and the array substrate (TFT) of the liquid crystal box (cell), it is necessary to stick an M8 screw on the four corners of the CF side and the TFT side of the product, and use the universal material test The machine will peel it off to evaluate whether the frame glue process capability meets the requirements. [0003] When conducting this test, it is required that the upper and lower screws must be aligned so that the stress points are in a straight line. In the daily test, it is generally manually aligned by personnel for bonding without the aid of other fixtures. [0004] Manual alignment errors are relatively large, and the upper and lower screws cannot be accurately aligned, which will lead to the final test results not meeting the require...
