The invention discloses an AOI vision detection device with an automatic overturning function. The AOI vision detection device comprises a bearing
machine box, the bearing
machine box is provided with a conveying belt for conveying PCBs to be detected, a detection
machine box is further arranged above the bearing machine box, and the detection machine box is internally provided with an automatic shooting camera, a
processing terminal and a display panel. One side of an inlet of the conveying belt is fixedly provided with a PCB bearing mechanism, and the PCB bearing mechanism comprises a foundation support, a vacuum sucking disc plate, an overturning motor and a grab
handle, the foundation support is fixed to the conveying belt, the vacuum sucking disc plate is fixed to the foundation support, the upper surface of the vacuum sucking disc plate is used for absorbing the PCBs to be detected, the overturning motor is arranged on one side of the foundation support, and the output end of the overturning motor is connected with the grab
handle to drive the grab
handle to grab and turn over the PCBs to be detected at the center of the conveying belt. By means of the AOI vision detection device, two faces can be detected at the same time through one-time conveying, a sucking disc is adopted for adsorption, taking, placing and fixing are facilitated, and detection efficiency is greatly improved.
