The utility model relates to the technical field of optical detection, and discloses an AOI automatic
optical testing machine feeding device which comprises a conveyor, one end of the conveyor is fixedly connected with a support, the top end of the support is fixedly provided with a mechanical arm, one side of the surface of the conveyor is fixedly provided with a connecting frame, and the surface of the connecting frame is provided with a positioning
assembly. A mounting frame is fixedly connected to the middle of the surface of the conveyor, and a dust brushing
assembly is mounted on the surface of the mounting frame. The positioning
assembly comprises a connecting frame, a first motor, a gear, two racks, two guide assemblies and two positioning plates. According to the automatic
optical testing machine, the positioning assembly is arranged so that the products cannot deviate when being placed on the conveyor, smooth grabbing of the mechanical arm is guaranteed so that feeding can be conducted on the AOI automatic
optical testing machine, dust on the surfaces of the products can be removed through the dust brushing assembly, interference to detection of the AOI automatic optical testing machine is prevented, and the judgment accuracy is improved.
