The invention relates to the technical field of automatic optical detection equipment, and discloses a double-sided AOI detection mechanism for a PCB, and the mechanism comprises a mounting rack, the top of the mounting rack and the outer side of the mounting rack are both fixedly provided with a machine base, and the outer side of the machine base at the top of the mounting rack is provided with an upper Y-axis driving motor. The outer side of an output shaft of the upper Y-axis driving motor is connected with an upper cross beam, an upper camera module is fixed to the outer side of the upper cross beam, a lower Y-axis driving motor is installed on the outer side of the machine base on the outer side of the installation frame, the outer side of an output shaft of the lower Y-axis driving motor is connected with a lower cross beam, and a lower camera module is fixed to the outer side of the lower cross beam. A fixed conveying plate is mounted in the mounting frame in a matched manner; and when the device is used, the upper camera module and the lower camera module are used in cooperation, the upper surface and the lower surface of the PCB can be detected at the same time, the detection speed is increased, and the problem that an existing AOI detection mechanism is long in detection time is solved.
Description
technical field [0001] The invention relates to the field of physics, in particular to optical detection technology, in particular to a double-sided AOI detection mechanism for PCB circuit boards. Background technique [0002] The AOI device is an automatic optical inspection device, which is based on the optical principle to detect common defects encountered by PCB boards. The machine automatically scans and collects images through the camera, checks the defects through image processing, and displays the defects through the display or automatic signs. Or mark it out for repairing by maintenance personnel; [0003] However, the existing PCB board production process sometimes needs to inspect the upper and lower sides, and the single-sided AOI inspection mechanism is used for inspection twice, which has the problem of long inspection time. Therefore, those skilled in the art provide a double-sided AOI inspection mechanism for PCB circuit boards to solve the problems raised i...
