The current intelligent visual inspection system can only detect the defects of the printed pattern, the defect of the hot stamping pattern and the offset of the position of the holographic pattern, but cannot be detected for the hidden problem of excessive hot stamping pressure. This is mainly because when the hot stamping pressure is too large, the paper fiber will break, and this cracking phenomenon cannot be observed from the surface of the paper, and it needs to be seen from the back to be seen, so the intelligent visual inspection system photographed from the surface of the paper This hot stamping quality problem cannot be found. At this time, it needs to be completed by some conventional detection means. For the flat-pressed flat-to-roll bronzing machine, the back light of the LED light source is used to perform on-line detection of the problem of excessive hot stamping pressure; On the roll-to-roll hot stamping machine, the back of the stroboscopic light source is used to perform on-line detection of excessive hot stamping pressure. The installation position of the back light source is shown in Figure 3.
