The invention discloses a full-automatic assembly line integrating feeding, positioning, film pasting and discharging. The full-automatic assembly line comprises a feeding assembly line, a film pasting assembly line, a feeding mechanical arm, a discharging mechanical arm and a visual positioning mechanism, wherein the film pasting assembly line is opposite to the feeding assembly line, the film pasting assembly line and the feeding assembly line are arranged at an interval to form a transferring space between the film pasting assembly line and the feeding assembly line; and the feeding mechanical arm, the discharging mechanical arm and the visual positioning mechanism are arranged in the transferring space. According to the full-automatic film sticking machine, material supply, positioning, feeding, thin film supply, film pasting and stacking operation are integrated on a unified assembly line for rhythmic and ordered operation through high-integration-degree design thinking, so that the transferring stroke of transferring materials back and forth among a plurality of assembly lines is greatly shortened, time waste caused in the transferring process is greatly reduced, the automation degree and the film and material supplying and stacking efficiency are remarkably improved, and the film pasting efficiency of the assembly line is greatly improved.
