FPC detection method and device, and FPC lamination method and device

The invention discloses an FPC (Flexible Printed Circuit) detection method and device, an FPC lamination method and device, the FPC detection method is applied to lamination equipment provided with a camera, and the detection method comprises the following steps: controlling a camera to respectively shoot images when a to-be-detected soft material moves to two preset positions to obtain two first images; obtaining first detection information from the two first images, the first detection information comprising a first contour image, a first angle parameter, a first length parameter and a first gray scale parameter; and performing material defect detection on the to-be-detected soft material according to preset reference information and the first detection information to obtain a detection result of the to-be-detected soft material. According to the invention, automatic detection can be carried out in the fitting period, the influence of human factors is reduced, the detection efficiency can be improved, and t
