An automatic loading and unloading system for circuit board double-sided AOI detection and its process flow

Abstract

The invention discloses an automatic plate feeding and discharging system for double-faced AOI (Automated Optical Inspection) of a circuit board. The automatic plate feeding and discharging system comprises a robot device, a feeding and discharging device, a double-faced dust sticking machine, a transferring device, an AOI machine, a butt joint device and a general control system for controlling the equipment to work, wherein the robot device is provided with robot mechanical arms; the double-faced dust sticking machine is located beside the feeding and discharging device; the transferring device is arranged above the feeding and discharging device and the double-faced dust sticking machine; the AOI machine comprises a face A detection and a face B detection machine; detection openings of the face A detection and the face B detection machine are opposite to the feeding and discharging device and the double-faced dust sticking machine; the robot device is located between the face A detection and the face B detection machine; and the butt joint device is located on one side of the face B detection machine and can be in up-down butt joint with the robot mechanical arms. The butt joint device can be in up-down butt joint with the robot mechanical arms so that time consumed by a plate overturning procedure is saved, and furthermore, a whole production process has relatively rapid efficiency; and the structure is compact so that the occupied area of equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of circuit board production, in particular to an automatic loading and unloading system for double-sided AOI detection of circuit boards and a process flow thereof. Background technique [0002] At present, in the process of PCB board processing and production, including AOI station feeding, labeling or inkjet station, manual loading and unloading PCB board station, PCB board needs to detect double-sided when A0I inspection is performed, in the entire PCB board processing production line It is necessary to arrange a large number of operators to operate each station. This original method of PCB board AOI production line not only has slow production efficiency and a large amount of labor, but also each station may be affected by human factors, resulting in defective products. Secondly, A0I During the inspection, only the A side of the PCB board can be detected first, and then the board is turned over manually,...

[0002] At present, in the process of PCB board processing and production, including AOI station feeding, labeling or inkjet station, manual loading and unloading PCB board station, PCB board needs to detect double-sided when A0I inspection is performed, in the entire PCB board processing production line It is necessary to arrange a large number of operators to operate each station. This original method of PCB board AOI production line not only has slow production efficiency and a large amount of labor, but also each station may be affected by human factors, resulting in defective products. Secondly, A0I During the inspection, only the A side of the PCB board can be detected first, and then the board is manually turned over, and then the B side is inspected. The production efficiency is very low. Therefore, our company has proposed an AOI inspection system for automatic upper and lower PCB boards. The patent number is 2015207224751, and the application date is On September 17, 2015, the system realized the purpose of loading and unloading the board by robots, greatly reducing labor force and improving production efficiency, but the following defects were found in the working process: 1. It needs to go through secondary dust sticking, which reduces production efficiency; 2. The overall layout Not compact enough, occupying a large production area
