Abstract

The invention provides an automatic optics testing device and method for PCBs. The automatic optics testing device comprises a conveying acceleration section, a steering corner temporary storage machine, a conveying storage position, an inductor and AOI equipment. The steering corner temporary storage machine is arranged at the conveying tail end of the conveying acceleration section. The inductor is arranged at the inner side of the steering corner temporary storage machine. The conveying storage position is arranged at one side of the steering corner temporary storage machine. The AOI equipment is arranged beside the conveying storage position. The invention further provides an automatic optics testing method for the PCBs. The method is implemented through the automatic optics testing device for the PCBs. The method comprises the following steps that 1, the PCBs are sequentially conveyed to the conveying acceleration section after being treated through a copper etching technology; 2, whether the PCBs reach the steering corner temporary storage machine is judged by means of the inductor, and when the PCBs reach the steering corner temporary storage machine, the steering corner temporary storage machine enables the PCBs to be steered and conveys the PCBs into the conveying storage position; the PCBs in the conveying storage position are conveyed into the AOI equipment; automatic optics testing is carried out on the PCBs by means of the AOI equipment.

Description

technical field [0001] The invention relates to the technical field of inspection in the production process of PCB boards, in particular to an automatic optical inspection device and method for PCB boards. Background technique [0002] In the production process of printed circuit boards (PCB boards), after the etching copper process (Developing / Etching / Stripping; DES) of the inner layer (InnerLayer) of the PCB board is completed, the boards are divided manually, and then the automatic optical inspection (AutomaticOpticInspection; Test the defect category and location on the AOI) equipment, and then check the defects on the defect detection confirmation and repair equipment (Verified&Repaired; VRS). However, the prior art has the following defects: a. low operating efficiency; b. hidden quality problems, which can easily cause scratches on the circuit of the PCB board. Contents of the invention [0003] In view of this, the present invention provides an automatic optical i...
