The upper part of the marking area moves back and forth. Due to the straight-line transmission of the laser, the optical path cannot be changed during the actual operation, so that the entire marking machine needs to move above the glass as a whole. Both the guide rail setting and the moving path setting are very complicated. Moreover, During the focusing process, the entire marking machine needs to move up and down as a whole to make the scanning head approach or move away from the glass in the height direction, which is very complicated and needs to be improved urgently.
