Problems solved by technology
[0004] However, the efficiency of this manual operation process is low, OK boards and defective boards are stacked together in sequence, and it is necessary to manually confirm the PCB boards one by one, which wastes the production efficiency and labor efficiency of the maintenance machine, and it is easy to cause damage to the PCB boards manually. The risk of scratches on the board surface increases the scrap rate

The invention discloses an automation method of a printed circuit board overhaul machine, a first code reading device, a second code reading device, a feeding arm, an overturning arm and a conveying mechanism are configured, the first code reading device is arranged to distinguish an OK board and an NG board of a board, the feeding arm separates and stacks the OK board and the NG board through feedback of a system, only the NG board performs the process of the overhaul machine, and the automation degree of the overhaul machine is improved. Therefore, the operation of overhauling the OK plate in the past is reduced, and the benefit of the overhauling machine is improved; the second code reading device is arranged to judge the front face NG or the back face NG of the plate, if the front face NG is the front face NG, the plate is directly fed into the overhauling machine, if the back face NG is the back face NG, the plate is turned over through the turning arm, and the plate is fed into the overhauling machine after being turned over to the back face, so that manual turning-over operation is reduced, the plate contact frequency of personnel and the probability of wrong face overhauling are reduced, and the working efficiency is improved. Therefore, the scratch risk of the board is reduced, and the rejection rate is reduced.
Description
technical field [0001] The invention relates to the technical field of printed circuit board production, and particularly discloses an automatic method for a printed circuit board inspection machine. Background technique [0002] In the production process of printed circuit boards (PCBs), automatic optical inspection (commonly known as AOI) is an important process to detect common defects encountered in the production process of circuit boards based on optical principles. After the rise of AOI, it has developed very rapidly. Many manufacturers use AOI equipment for quality inspection and become the standard equipment in the production process of printed circuit boards (PCBs). [0003] After the AOI process is completed, the next process is that after the PCB board is detected by the AOI optical identification system, the PCB board with the defective circuit is confirmed, and the serial number is printed on the board surface by the inkjet printer and the defect point is recor...
