  • Patent number: 8061959
    Abstract: The present invention relates to a board inverter and a boarding inverting system. The board inverter includes a support, a first board picking device, an second board picking device and a controller. Each of the first board picking device and the second board picking device includes a driving mechanism and a first board picking device. The driving mechanism comprises a first linear driving means mounted on the support, a second linear driving means mechanically coupled to the first linear driving means, and a rotary driving means attached to the second linear driving means. The controller is connected to all the power supply members. The controller controls the motion of the first board picking device and the second board picking device such that the first board picking device and the second board picking device cooperatively inverting workpieces transmitted on a production line. The board inverter can be installed on a production line without altering the arrangement of existing production line.

  • Patent number: 7872744
    Abstract: An exemplary visual inspection apparatus for a flexible printed circuit board includes a frame, an inspection station, a control system, a roller system and a power system. The inspection station is disposed on the frame. The inspection station has an inspection surface for placing the flexible printed circuit board thereon for visual inspection. The roller system includes a first roller for unwinding a flexible printed circuit board therefrom and a second roller for winding up the flexible printed circuit board therearound. The power system includes a driving device and a braking device. The driving device includes a torque motor engaging with the second roller to drive the second roller to roll. The braking device includes a detent engaging with the first roller to stop rolling of the first roller. The control system electrically connects to the power system for controlling the power system.
