Problems solved by technology

[0006] In order to overcome and make up for the lack of effective means and process devices for precise detection and control of the lag angle in the existing optical fiber precision wiring technology, and the technical deficiencies and defects that cannot meet the precision wiring requirements of the winding when the optical fiber is precisely and automatically wound, the present invention provides a A lag angle precision detection device capable of adjusting feeder height. It installs the industrial CCD camera and strip light source on the lifting plate of the feeder height adjustment device through the frame body assembly, and aligns the lens of the industrial CCD camera directly below. The moving optical fiber between the feeder wheel and the bobbin; when the number of fiber winding layers increases, the lifting plate will drive the fiber feeder wheel, industrial CCD camera and strip light source to rise simultaneously; by increasing the feeder height of the feeder wheel, the feeder wheel and The optical fiber between the bobbins is always kept horizontal, which improves the spatial accuracy of the lag angle measurement; and keeps the distance and angle of the industrial CCD camera and the bar light source for shooting and illuminating the fiber constant, ensuring the lag angle image The same shooting conditions greatly reduce the shooting error of the lag angle image, realize the precise detection of the lag angle in the process of precise wiring, and provide a powerful technical means for the realization of precise wiring
