Design of Bending Fatigue Machine for Flexible Electronics
According to the current requirements of bending fatigue test for flexible electronics, a bending fatigue machine based on SCM (single chip Microcomputer) has been designed. using stepper motor driving screw nut body as loading mechanism, improve the accuracy of the structure effectively by gaps eliminator, and achieve the requirement of precision control by using fraction driving technology in the motor control. Photoelectric counter and electrical signals detection circuit have also been designed to achieve unattended function. This design plays an important role in the following testing process.
