The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. It should be noted that, in the case of no conflict, various features in the embodiments of the present invention may be combined with each other, and the combined embodiments are still within the scope of the present invention.

In the description of the present invention, it should be noted that the terms "first", "second", "third", and the like are used only for distinguishing the description, and are not intended to indicate or imply relative importance.

The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In one aspect of the embodiments of the present invention, there is provided a two-dimensional material transfer apparatus, as shown in fig. 1, including: the device comprises a feeding device A, a hot pressing device B, a separating device C, a cleaning device D, a drying device E and a receiving device F, wherein the feeding device A can provide a target film (the quantity of the target film can be flexibly set according to the single-sided or double-sided growth of two-dimensional materials of the metal film A011), a metal film A011 with two-dimensional materials grows on at least one side, the metal film A011 and the target film are conveyed to the hot pressing device B, the hot pressing device B presses the target film and the metal film to form a composite film with the metal film A011/the target film, the composite film is conveyed to the separating device C, the characteristic that the two-dimensional materials can be separated from the metal film A011 through the separating device C is realized, the two-dimensional materials originally attached to at least one side of the metal film A011 are transferred to the target film, the transfer of the two-dimensional materials is realized, and the target film attached with the two-dimensional materials can be cleaned and dried through the, the collecting device F collects the target film attached with the two-dimensional material, the target film is convenient to serve as a raw material of a follow-up two-dimensional material processing device F05 (a two-dimensional material element production line), an automatic production line for transferring the two-dimensional material can be formed through operations of discharging, hot pressing, separating, cleaning, drying and collecting, and therefore efficiency and productivity are improved, meanwhile, production cost can be reduced, and occupied area of equipment is saved.

In addition, the single-side or double-side transfer process of the two-dimensional material can be correspondingly realized through different situations of the two-dimensional material grown on the single side and the double side of the metal thin film A011, for example, when the two-dimensional material is grown on the single side of the metal thin film A011, one target thin film can be set as one, and one target thin film corresponds to the side, on which the two-dimensional material is grown, of the metal thin film A011; when two-dimensional materials grow on the two sides of the metal thin film A011, the two target thin films can be set to be two, and the two target thin films can respectively correspond to the two sides of the metal thin film A011, which are grown with the two-dimensional materials, so that enterprises can flexibly adjust productivity according to production requirements of different stages. In the case of single-sided transfer, the level of the composite film may be a target film/two-dimensional material/metal film, and in the case of double-sided transfer, the level of the composite film may be a target film/two-dimensional material/metal film/two-dimensional material/target film.

As shown in fig. 1, the discharging device a can be correspondingly provided with two or more discharging mechanisms according to single-sided transfer or double-sided transfer, that is, discharging of different films is realized through different discharging mechanisms, so that each discharging mechanism can discharge independently, and mutual interference is avoided. Meanwhile, in order to improve convenience of layout, the first discharging mechanism a02 may be disposed at one side of the raw material discharging mechanism a01 during single-side transfer, so that the target thin film and the metal thin film a011 can be made to correspond to each other on the side where the two-dimensional material is grown. In the case of double-sided transfer, the first discharge mechanism a02 and the second discharge mechanism a04 may be located on opposite sides of the raw material discharge mechanism a01, that is, the raw material discharge mechanism a01 may be located between the first discharge mechanism a02 and the second discharge mechanism, so that when the raw material discharge mechanism a01, the first discharge mechanism a02, and the second discharge mechanism a04 respectively convey their respective films to the hot press apparatus B, the first target film a021 may be made to face one side of the metal film a011, and the second target film a041 may be made to face the other side of the metal film a 011.

When the hot-pressing device B receives the target film and the metal film A011, the target film is hot-pressed and attached to the front surface of the metal film A011 through a hot-pressing process, and different composite film forms of the target film/two-dimensional material/metal film or the target film/two-dimensional material/metal film/two-dimensional material/target film can be respectively and correspondingly formed according to the difference of single-side transfer and double-side transfer. The temperature of each film can be improved through the effect of heat conduction through the hot pressing device B, so that the pressing tightness of each film is improved, and the stability of subsequent two-dimensional material transfer is ensured.

After receiving the composite thin film, the separation device C separates the two-dimensional material from the metal thin film a011 by its own separation characteristic, that is, the two-dimensional material grown on the surface of the metal thin film a011 can be separated from the surface of the metal thin film a011 and transferred to the surface of the target thin film.

After the separating device C separates the composite film, the target film with the two-dimensional material attached to the surface thereof is conveyed to the receiving device F, and the receiving device F correspondingly receives and collects the target film with the two-dimensional material attached thereto. The material receiving device F can collect a target film attached with two-dimensional materials by the second material receiving mechanism F02 when the single-side transfer is performed, and can correspondingly collect two target films attached with two-dimensional materials by the second material receiving mechanism F02 and the third material receiving mechanism F03 when the double-side transfer is performed. The receiving device F may further include a first receiving mechanism F01, and the first receiving mechanism F01 collects the metal thin film a011, which is conveyed out of the separating device C and has the surface from which the two-dimensional material is removed, so that the metal thin film is recycled or recovered while the two-dimensional material primary product is output.

The cleaning solution may be distilled water or deionized water.
