[0002] After the foldable screen mobile phone is assembled, it is necessary to conduct a bending test on the bending performance to detect durability. A rotating shaft is provided between the upper part of the foldable screen mobile phone and the lower part of the foldable screen mobile phone. During the test, the lower part of the foldable screen mobile phone remains stationary, and the upper part of the foldable screen mobile phone rotates around the rotating shaft to form an angle of 0-180° with the lower part of the foldable screen mobile phone. In the current conventional testing methods, manual testing is usually used to test the bending performance. The operator manually bends the foldable screen mobile phone within a standard time period, but the manual operation method is prone to problems such as the bending angle is not fixed each time and the number of bends may not meet the standard, and the efficiency is low. Another existing detection method is to use special detection equipment for bending test, but during the detection process, the foldable screen mobile phone is prone to displacement during the bending operation.
