The application discloses an automatic electrochemical aluminum
stamping foil online detection device, and belongs to the technical field of electrochemical aluminum
stamping foil online detection. The device support is provided with a multispectral
light source group, the multispectral
light source group is distributed on both sides of the industrial camera, a guide mechanism for guiding workpiece conveying movement is arranged between the feeding roller shaft and the winding roller shaft on the device support, a balance roller shaft for adjusting workpiece conveying fluctuation is movably arranged between the feeding roller shaft and the winding roller shaft, two groups of balance roller shafts are symmetrically arranged on the device support with respect to the industrial camera, and a moving mechanism for regulating the position of the balance roller shaft is arranged on the device support. Under the limiting action of the balance roller shaft, the tension fluctuation during the movement and conveying of the electrochemical aluminum
stamping foil can be effectively reduced, the definition of the foil surface image collected during detection is improved, and the online detection quality is maintained.
