[0032] like Figure 1-Figure 4 As shown, the principle of the graphene conductive ink transfer printing device provided in this embodiment is as follows: the first screw 18 is driven to rotate by the position control positioning motor 13, and the rotating first screw 18 drives the positioning plate 15 to move to the required position, and after the printed matter is placed on the printing table 8 and pushed against the rubber plate 16, the output end of the positioning cylinder 7 extends to drive the positioning block 9 and the rubber block 10 to stabilize the printed matter;

After the No. 1 screw rod 18 drives the positioning plate 15 to move a certain distance away from the printed matter, under the action of the lifting cylinder 4 and the pad printing cylinder 21, the pad printing head 23 collides with the printed matter and transfers the print to the printed matter. After the output end of the lifting cylinder 4 and the output end of the positioning cylinder 7 are retracted, the printed matter is moved out of the printing table 8.

[0035] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction.
