Description

Technical Field

[0001] The utility model relates to the technical field of a hundred-grid testing device, in particular to a hundred-grid testing fixture. Background Art

[0002] When touch screens and displays are manufactured, the adhesion test method for pattern film layers is evaluated by a 100-grid test. The adhesion of the film layer and the pattern is currently tested by using a blade and a ruler to draw a 100-grid pattern in the horizontal and vertical directions on the surface, and the adhesion is determined by sticking 3M tape on the area where the grid is drawn. However, since personnel need to use a ruler to draw, resulting in inconsistent sizes of each piece, and there is a probability that the length of the draw will be damaged if personnel control the draw length (the area is not controlled), and there is a risk that the ruler will scratch the product. Therefore, a 100-grid test fixture is designed. By using a special test 100-grid fixture, equal length horizontal and vertical (different angles, different widths) straight lines are opened on a board for drawing 100-grid patterns. A soft anti-scratch pad is designed at the bottom of the fixture to solve the problems existing in the current 100-grid test. Utility Model Content
