Description

Technical Field

[0001] The utility model relates to the technical field of graphene processing, in particular to a coating mechanism for a graphene composite layer. Background Art

[0002] At present, some products on the market use metals for heat conduction and heat dissipation, especially copper and aluminum. Although copper has high thermal conductivity, its heavy weight and easy oxidation limit its application. The thermal conductivity of aluminum is not high, and it is difficult to meet the needs of existing products for thermal conduction and heat dissipation. The heat dissipation films made of natural graphite materials and synthetic graphite materials currently in use have improved the heat dissipation of electronic products to a certain extent. Graphite heat dissipation films are mainly made by directly rolling graphite after processing, as well as by polymer carbonization, graphitization and other methods. Due to the limitations of the material's own planar thermal conductivity and the limitations of the graphite film process, the size of most graphite films is tens of centimeters, so the graphene heat dissipation film needs to be cut.

[0003] The utility model with application number CN202322042144.0 discloses a graphene heat dissipation film flat cutting structure, which belongs to the field of heat dissipation film processing technology. The key points of its technical solution include a base plate, a fixed shaft is bolted on the top of the base plate, a workbench is bolted on the top of the base plate, a rotating component is bolted on the top of the workbench, a lifting component is bolted on the top of the workbench, and an adjusting component is arranged inside the lifting component. When workers cut the graphene heat dissipation film, by setting the lifting component, the workers start the lifting motor to drive the threaded rod provided in the lifting groove on the inner side of the vertical plate to rotate, thereby driving the adjusting component to move up and down. By setting the adjusting component, it is achieved that when workers cut the graphene heat dissipation film, there is no need for manual cutting, thereby avoiding deviation of the graphene heat dissipation film during the cutting process, and therefore will not cause damage to the graphene heat dissipation film.

[0004] When the existing graphene cutting device is cutting, the graphene membrane is easily heated up when in contact with the rotating cutting knife. Since the membrane is composed of polyethylene material, the structure of the membrane will be destroyed when heated, resulting in jagged edges at the cut part. Part of the membrane may also melt, resulting in uneven edges of the cut membrane. Utility Model Content

[0045] Furthermore, a third linear module 37 is arranged along the length direction of one of the guide rail base plates 31, and the driving end of the third linear module 37 is connected to the guide rail sliding seat 32; the third linear module 37 drives the guide rail sliding seat 32 to move along the length direction of the guide rail base plate 31 to adjust the position of the coating module so that the coating module is close to or away from the cutting area.

[0046] The roller conveying mechanism 1 includes a roller conveying frame 11, and roller conveying rollers 12 are respectively installed at both ends of the roller conveying frame 11 and the bottom of the roller conveying frame 11. A roller conveying belt 13 with a circular runway structure is nested through multiple roller conveying rollers 12.
