TECHNICAL FIELD

[0001] The present application relates to the technical field of roll pressing and bonding device, in particular to a graphene heating pad roll pressing and bonding device. BACKGROUND

[0002] The graphene heating pad is a new type of surface heating type automobile heating pad, which has the advantages of thin thickness, soft texture, uniform temperature, fast heat transfer, good experience and safety and reliability, and will gradually replace the resistance wire type heating pad. The heating function of the graphene heating pad mainly depends on the electrode spacing, the sheet resistance of the graphene film and the electrical contact between the electrode and the graphene film. When the electrode spacing and the sheet resistance of the graphene film are determined, the heating performance and performance consistency of the heating pad are mainly affected by the electrical contact between the electrode and the graphene film. The electrical contact between the electrode and the graphene film is determined by the bonding process. Therefore, it is very important to use a consistent and effective bonding process.

[0003] There are two main existing bonding processes, one is manual bonding, that is, manually pasting electrodes on the graphene film, or manually pasting graphene film on the electrode conductive adhesive layer. This method is a pure manual method, and due to human interference and unstable sheet fixation, the electrode spacing and bonding quality cannot be guaranteed. The other is jig fitting, the graphene film is first placed flat in the jig, and then fixed by pressing block / strip or vacuum suction plate, and then the electrode film is positioned on the jig by positioning pin, and then manually or plate bonding is performed, or the electrode conductive adhesive layer is first fixed outward in the jig, and then the graphene film is bonded. Although this method has improved quality and efficiency compared with manual bonding, it still cannot meet the high requirements of the automotive field for product quality and batch consistency, and cannot realize mass production. In addition, due to the softness and thinness of the graphene film, the above two bonding processes will also produce bubbles or wrinkles, and thus a graphene heating pad roll pressing and bonding device is invented to solve the above problems.
