AOI vision detection device with automatic overturning function

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of optical detection, and in particular relates to an AOI visual detection device with an automatic flip function. Background technique [0002] AOI (Automatic Optic Inspection), also known as automatic optical inspection, is a device based on optical principles to detect common defects encountered in PCB board welding production. At present, the AOI visual inspection devices on the market can only detect the solder joints on one side of the PCB board, and only after manual flipping can the solder joints on the other side of the PCB board be inspected, which reduces the detection efficiency. The board is fixed, and it is inconvenient to disassemble and assemble, which further reduces the detection efficiency. In addition, the existing AOI visual detection device has a large volume and is inconvenient to move and replace.
