The invention provides a full-automatic film laminator and a control method thereof. The full-automatic film laminator comprises a base, a base board fixed on the upper surface of the base and a film laminating assembly arranged on the base board. The full-automatic film laminator also comprises material transfer assemblies used for loading and unloading of the film laminating assembly and a control assembly in control connection with the film laminating assembly and the material transfer assemblies. According to the control method, double film laminating stations are matched with double mechanical loading arms to perform cycle operation, each of the two material transfer assemblies includes a first material transfer assembly for loading and a second material transfer assembly for unloading, the two transfer assemblies are arranged symmetrically around a cabling rod and responsible for a motion area within 180 degrees respectively, films can be conveyed to the film laminating stations or unloaded from the film laminating stations to a discharging pipeline through 90-degree lateral motion of the first material transfer assembly and the second material transfer assembly, the collaborative arrangement and the control method effectively increase production efficiency and reduce control difficulty, the collaborative arrangement is more compact than tandem arrangement of double material transfer assemblies, and high efficiency is achieved. The full-automatic film laminator and the control method thereof guarantee production efficiency and save labor. In addition, the operation interface is a man-machine interface, accordingly the overall structure is compact and performances are stable and reliable.
