The invention provides a full-automatic multifunctional laminating machine comprising a machine frame, a first X axis linear motion module group, a second X axis linear motion module group, a Y axis straight line motion module group, a laminating platform, two laminating heads, double carrying feeding discharging arms, two feeding devices, a feeding box, and a discharging box. The laminating machine is provided with the double carrying feeding discharging arms, and then the feeding and the discharging can be carried out at the same time, and therefore FPC board conveying time can be saved. A plurality of laminating machines can be assembled in a cooperated manner, and by adopting a way of sharing the feeding box and the discharging box, the continuous laminating production of the FPC boards can be realized, and reinforced sheets of various specifications can be laminated continuously. The two laminating heads and the corresponding feeding devices are used to absorb the reinforced sheets alternately and repeatedly, and are attached to predetermined positions to be provided with the FPC in an attached way, and therefore laminating efficiency is greatly improved. Meanwhile, an image processor is provided in a matched manner, and the laminating precision is improved. The laminating heads are provided with springs, and by controlling the amount of compression of the springs, the pressing strength of the laminating heads applied to the FPC boards during the laminating can be controlled, and the FPC boards can be prevented from being damaged.
