AI Technical Summary
Existing methods for testing laptop screen hinges rely on manual operation, which makes the results highly susceptible to subjective factors and unable to accurately measure the stress state and wear degree of the hinge at different angles.
A motor drives a rotating rod to apply force to a hook scale, and an angle gauge is used to measure the mechanical state of the rotating shaft at different angles. The hook scale measures the tensile force data and the angle gauge monitors the opening and closing angle of the screen to form an angle-mechanical data pair.
It achieves accuracy and consistency in shaft inspection, reduces human error, provides quantitative assessment of shaft wear and durability, and improves inspection efficiency and accuracy.
