Full-automatic FPC (flexible printed circuit) board appearance test unit and corresponding appearance test method

Abstract

The invention provides a full-automatic FPC (flexible printed circuit) board appearance test unit and a corresponding appearance test method. The full-automatic FPC board appearance test unit includesa first appearance test device, a second appearance test device, a feeding platform, a discharging platform, a transfer system, a feeding manipulator and a discharging manipulator. The full-automaticFPC board appearance test unit has the advantages that the feeding manipulator positions and grips an FPC board on the feeding platform to the first appearance test device to carry out photographic appearance test on one side, the transfer system then turns over the FPC board tested by the first appearance test device, corrects the FPC board and transfers the FPC board to the second appearance test device so that photographic appearance test is performed on the other side, the FPC board is finally gripped and discharged to the discharging platform by the discharging manipulator, testing is automated, and testing efficiency is high.

Description

technical field [0001] The invention relates to the field of FPC detection equipment, in particular to a fully automatic FPC board appearance inspection machine and a corresponding appearance inspection method. Background technique [0002] FPC board is a kind of flexible printed circuit board, which is a kind of flexible and windable printed circuit made of polyimide or polyester film as the base material. An important carrier or key connection means that is indispensable to the product. With the development of electronic products towards light, thin, small and compact, the precision of FPC and the complexity of the manufacturing process are increasing, and more stringent requirements are placed on the quality control of FPC; [0003] Among them, due to the flexibility and bendability of the FPC board, it is inconvenient to operate it, making automatic detection more difficult. Therefore, at present, the appearance defects in the manufacturing process of the FPC board main...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a fully automatic FPC board appearance inspection machine, which is positioned by a feeding manipulator, grabs the FPC board on the feeding platform, and transports it to the first appearance inspection device for one-side appearance photo inspection, and then transfers the first appearance through the transfer system. The FPC board that has been inspected by the first appearance inspection device is turned over, calibrated and transported to the second appearance inspection device, and the appearance of the other side is photographed for inspection, and finally the output manipulator grabs and outputs it to the output platform to realize automatic inspection. Solve the problem that the appearance of the FPC board is detected by manual operation in the prior art, resulting in low detection efficiency
