Turnover mechanism for printed circuit board

A printed circuit board (PCB) panel turnover mechanism is installed at the PCB automatic production line or automatic detection line. The mechanism includes an upper and a lower drive component respectively in symmetry and upright installation at both sides of the production line or detection line, and clamp components capable of moving from top to bottom for clamping and rotating the PCB are provided on the upper and lower drive components. The inventive mechanism can be directly mounted beside the conveyor belt of the production line or detection line of the PCB to fulfill the continuous turnover of PCB in the transfer process. The invention has advantages of compact structure, greatly improved production efficiency, and a wide range application.
