Maintenance equipment and maintenance method for online maintenance of PCB

Abstract

The invention relates to maintenance equipment for online maintenance of a PCB, which is connected with an AOI maintenance system through a board feeding conveying section and comprises a board separation conveying section and the board feeding conveying section. An induction device is arranged on the board separation conveying section; a first OK board conveying device is connected with the boardseparation conveying section; a board collection conveying section is connected with an NG board conveying device; the NG board conveying device is connected with the board separation conveying section, is positioned at the rear end of the board separation conveying section and is used for conveying NG boards; a rechecking machine is positioned at the right end of the NG board conveying device; and a second OK board conveying device is positioned between the rechecking machine and the board collection conveying section. According to the maintenance equipment for online maintenance of a PCB, assembly line production is achieved, the situation that the OK board is scratched due to the fact that the OK board and the NG board are overlapped together is avoided, the rejection rate of the PCB is reduced, meanwhile, the production efficiency is improved, and automatic production is achieved; the invention also provides a maintenance method for the maintenance equipment for online maintenanceof a PCB by using the maintenance equipment for online maintenance of a PCB.

Description

technical field [0001] The invention relates to the technical field of PCB boards, in particular to an inspection equipment for online repair of PCB boards and an inspection method thereof. Background technique [0002] After the AOI process of PCB is completed, the routine process is that after the PCB board is detected by the AOI optical recognition system, the PCB board with defective lines is confirmed, and the serial number is printed on the board surface by the inkjet printer and the defect point is recorded, OK board and defective board (NG boards) are stacked together in order, moved to the side of the re-inspection machine by a transport vehicle, manually retrieve the AOI data, and according to the serial number of the board side, confirm the defect points and repair the defect points one by one, and at the same time after the repair The defective boards are stacked together with the OK boards in order, and then run to the next process. However, the efficiency of t...

Problems solved by technology

However, the efficiency of this operation process is low, and the scrap rate of PCB boards is high. The specific reasons are as follows:

[0003] 1. OK boards and defective boards are stacked together in order, and need to be confirmed one by one, which wastes the production efficiency and labor efficiency of the re-inspection machine;
