The PLC controller determines the required stamping position based on the image information. Driven by the first servo motor 101, the second servo motor 108, and the rotary motor 114, the robotic arm contacts the paper to stamp it at the appropriate position; after the first side is stamped, the robotic arm moves upward.

[0040] The electric push rod 403 extends, the flip plate 401 tilts, and the paper falls to the bottom of the flip roller 402. The fifth servo motor drives the flip roller 402 to rotate, and the flip roller 402 rolls the paper into the space between the two flip rollers 402, and then discharges it from between the flip rollers 402 back to the reset flip plate 401.
