PCB appearance on-line maintenance device and maintenance method

Abstract

The invention discloses a PCB appearance on-line maintenance device. The PCB appearance on-line maintenance device includes an on-line AOI machine, an annular maintenance unit and a browning line, wherein the on-line AOI machine, the annular maintenance unit and the browning line are successively connected; and the annular maintenance unit includes an annular conveyer belt and an automatic maintenance machine which is connected with the annular conveyer belt. The PCB appearance on-line maintenance device has the advantages of implementing on-line maintenance of PCB appearance, avoiding carrying PCBs for multiple times, improving the processing efficiency, reducing the labor intensity, reducing the probability of scratching of the surfaces of the PCBs because the PCBs are carried manually.A maintenance method is also disclosed. After the on-line AOI machine detects the appearance of the PCBs, qualified PCBs can be directly conveyed to the browning line for browning processing, and PCBwith defective appearance are conveyed to the automatic maintenance machine for maintenance and then are conveyed to the browning line for subsequent browning processing after being qualified throughmaintenance. The maintenance method has the advantages of being high in level of mechanization, greatly reducing the number of carrying boards manually, improving the processing efficiency and qualityof products, and being suitable for industrial mass maintenance of PCBs.

Description

technical field [0001] The invention belongs to the technical field of printed circuit board production, and in particular relates to PCB appearance maintenance equipment and a maintenance method. Background technique [0002] Printed circuit board (PCB), also known as printed circuit board, printed circuit board, or printed board for short, usually uses an insulating board as the base material, on which at least one conductive pattern is attached, and is equipped with such as component holes, fastening holes, metal Pore ​​structures such as chemical holes are used to replace the chassis of traditional electronic components and realize the interconnection of electronic components. With the rapid development and popularization of smart electronic products, and the continuous development in the direction of thinning and high density, the requirements for the output and quality of PCB are getting higher and higher, and the wiring of PCB is becoming more and more dense, which ma...
