[0002] The production process of flexible printed circuits (FPC) is complex and varied, and the manufacturing conditions of different items and styles vary greatly. With the rapid iteration of electronic products, the requirements for the quality and inspection speed of FPC are becoming increasingly stringent. For a long time, the inspection of product appearance has mainly relied on manual labor, which is not only costly, but also has limited inspection effects, and can often only detect relatively obvious abnormalities.

[0003] The Chinese invention patent "An FPC Bare Board Appearance Defect Inspection Machine" with publication number CN113277326A turns over the workpiece that has been inspected on the front side at the upstream station through a turning station, and then the downstream station takes the turned workpiece and inspects the back side of the workpiece. This method has the following problems:

[0004] One is that the inspection equipment conveyor line is long and the equipment occupies a large area;

[0005] The second is to add a flipping station, and the efficiency of front and back inspection of FPC is low;

[0006] The third is that after the FPC is turned over, its front side contacts the jig as a supporting surface, which may cause the front side of the FPC to collide with the jig and produce defects such as scratches. Utility Model Content
