Specifically, the screen frame driving device is an XXY precision positioning platform, and the XXY precision positioning platform is used for controlling the screen frame to move or rotate in a horizontal plane. In addition, the XXY precision positioning platform also has the function of controlling the screen printing frame to move up and down, when the boundary of the pattern to be printed is overlapped with the boundary of the object to be printed 6, the XXY precision positioning platform controls the screen printing frame to descend to a position which is a preset distance away from the object to be printed 6, then printing is carried out, and after printing is finished, the screen printing frame is controlled to move up.
In particular, the conveying device is preferably a transfer robot 2, and the transfer robot 2 can adsorb the object 6 to be printed and then transfer the object onto the screen printing platform 7. In addition, the robot arms such as a DELTA robot, a SCARA robot, a six-axis robot and the like can be used for transferring the objects.
In order to ensure the continuity of material conveying, the baking and feeding device is preferably a conveyor belt 4, and the conveyor belt 4 is provided with a grill 5 for containing the printed objects. The conveyor belt 4 is preferably arranged at the side of the frame and the transfer robot 2 is preferably arranged between the conveyor belt 4 and the frame, wherein the conveyor belt 4 can also convey the objects 6 to be printed. At specific during operation, the accessible is artifical will treat that printed object 6 places on gridion 5 to stack in stock district 1, and the conveyer belt 4 is put to gridion 5 accessible climbing mechanism on the stock district 1, and gridion 5 moves to the stock district 3 along with conveyer belt 4, transports manipulator 2 and will treat that printed object 6 adsorbs, then shifts to silk screen printing platform 7 on, after the printing is accomplished, the rethread transports manipulator 2 and shifts article to gridion 5 on, carries article to toasting equipment through conveyer belt 4 at last.
