ABSTRACT:
A thickness measuring device of a laminating machine includes a mount, a stepper motor, a screw rod, a first contact-activated element, a second contact-activated element, and a microcontroller unit. The stepper motor is coupled to the mount. The screw rod is interlocked with the stepper motor. The first contact-activated element is provided at a position corresponding to and some distance below the screw rod. The second contact-activated element is provided at a position corresponding to and some distance above the screw rod. The microcontroller unit is electrically connected to the stepper motor, the first contact-activated element, and the second contact-activated element so as to provide initialization setting and exercise judgment and control after receiving a thickness measurement. Thus, the thickness of an object to be detected can be conveniently measured.
