Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of AFG material cutting, and particularly relates to a cutting device for AFG material preparation and an operation method thereof. BACKGROUND

[0002] The AFG material is a composite material, and metal atoms are planted in a graphite sheet layer structure to solve the disadvantage of graphite interlayer thermal conduction by electronic thermal conduction. The thermal conduction mechanism is between metal materials and non-metal materials, that is, both phonon thermal conduction and electronic thermal conduction, so that the longitudinal thermal conduction of the material is high, the heat dissipation effect is very good, and the material has very good thermal conductivity, electrical conductivity, high strength, super large storage and conduction of heat and other characteristics. The material is widely applied to the fields of electronic products, lithium ion battery electrode materials, solar cell electrode materials, composite material preparation, electronic information and has a broad application prospect. Because the material has good heat storage and dissipation characteristics, especially in the 5G era, electronic communication equipment needs better heat dissipation and storage materials as a medium to conduct heat generated by the equipment, so as to ensure the electronic stability of the equipment and ensure the normal operation of the equipment and better use of the equipment.

[0003] As a heat dissipation material, the AFG film material needs to be cut and attached to the heat dissipation structure of the equipment, such as the mainboard in a notebook computer. The AFG sheet needs to be cut according to the structure of the mainboard to adapt to the shape of the product. Because the parts on the mainboard are precise, the AFG sheet needs to be cut accurately.

[0004] At present, AFG material cutting is mostly carried out by an automatic laser cutting machine. The sheet is placed under the laser cutting head for automatic cutting. Because the AFG is a relatively thin film sheet, it is difficult to position on the cutting table of the automatic laser cutting machine. Under the influence of equipment vibration and external environment, cutting deviation is easy to occur, and the cutting yield is low. Especially when loading, the positioning deviation is more likely to occur when conveying from the loading position to the cutting position, which further reduces the cutting precision. At the same time, it is also difficult to achieve accurate unloading after cutting. SUMMARY
