Referring to fig. 11, one side of the material preparing platform 191 is further provided with four blowing pipes 197, when the material loading suction cups 113 suck the sheets on the material preparing platform 191, the four blowing pipes 197 are used for blowing the excess sheets away from the material loading suction cups 113, and the four blowing pipes 197 are symmetrically arranged and located above the long side of the material preparing platform 191.

The utility model discloses a full-automatic printing machine's theory of operation:

the first step is as follows: placing the sheet on the stock preparation table 191, and adjusting the stock preparation table 191 to a proper position;

the second step is that: sucking the sheet on the material preparing platform 191 by the material loading mechanical arm 11, separating the redundant sheet from the material loading mechanical arm 11 by the rotary brush 195, the strip brush 196 and the air blowing pipe 197, and conveying the residual sheet to the material loading platform 12;

the third step: the feeding platform 12 is adjusted to a proper position through the matching of the CCD camera 16 and the XYZCCD automatic positioning platform 13;

the fourth step: printing a pattern on the sheet by the screen printing module 14;

the fifth step: the sheet on the stock table 191 is sucked by the feeding robot 15 and conveyed to a target position.

This is the operation of the fully automatic printing press of the preferred embodiment.

In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, so that the scope of the present invention shall be determined by the scope of the appended claims.
