The high-speed development of touch display devices has promoted the industry of cover glass to be continuously strong, and electronic devices with screens, such as notebook computers, tablet computers, mobile communication terminals, liquid crystal screens and other testing machines, have higher and higher requirements on the quality of the cover glass, so that the impact resistance of the machine body needs to be tested.
At present, the industry basically adopts a falling ball impact testing machine to test the impact resistance, and the falling ball testing machine is the most important equipment in the processing test of cover plate glass. Most of the adopted testing machines align the center point of the falling ball with the testing point of the tested object by visual inspection, and calculate the falling ball impact force by simply measuring the mass and the falling height of the steel ball.
However, due to the size of the steel ball, the falling distance of the steel ball, or the deviation of the falling position during the test, there are the following disadvantages: when the heights of steel balls with different diameters or the height of a movable steel ball clamp and a sample wafer are changed, the change of the positioning central point often ensures that the central position cannot be ensured, the steel ball deviation condition can occur, when the vacuum suction of a steel ball suction nozzle disappears, the steel ball can fall in a free falling body motion, and thus the falling point of the steel ball is inaccurate.
