As will be readily apparent to those skilled in the art.
In the initial state, the labeling mechanism is positioned at the starting point of the horizontal driving mechanism to stand by, and the distance between the starting point of the horizontal driving mechanism and the industrial camera is required to be determined by the advancing speed of the electrolytic copper foil and the data processing speed of an external processing terminal. When the number of pinholes in the picture shot by the industrial camera is counted to be larger than a preset value by the external data processing terminal, the shot part of the copper foil does not reach the starting point of the horizontal driving mechanism yet. The horizontal driving mechanism starts to operate when the photographed portion of the copper foil reaches the start point of the horizontal driving mechanism. This is calculated from the speed at which the equipment processes the data and the speed of movement of the copper foil.

The inner bottom surface of the shading ring belt 2i is attached to the bottom surface of the shading strip 2 g. In order to prevent the copper foil edge from being rubbed with the upper end plate to cause damage, the width of the copper foil is smaller than the lengths of the second guide roller and the third guide roller, so that gaps exist between the electrolytic copper foil wide edge and the upper end plate, the light gaps of the lower light source can be blocked from entering the light shading ring formed by matching the upper light shading plate and the upper end plate by arranging the light shading ring belt and the light shading strip, the inside of the light shading ring can be a darkroom when the copper foil passes through, and the industrial camera is prevented from being disturbed.
