Technical Field

[0001] The utility model is applied to the technical field of aluminum-based copper-clad plate production, and particularly relates to an aluminum plate coating device. Background Art

[0002] The main material of aluminum-based copper-clad laminate is aluminum plate, which needs to be cut and surface treated before copper foil lamination. Therefore, in the early processing, the aluminum plate is subjected to chemical treatment and mechanical punching and cutting impact. Therefore, in order to ensure that the aluminum plate can be better bonded with the thermal conductive material and copper foil, it needs to be cleaned, anti-oxidized, and surface brushed before lamination.

[0003] The two surfaces of the aluminum plate are the outer surface and the brushed surface. The outer surface needs to be treated with an anti-oxidation agent, and the brushed surface needs to be modified. The usual treatment process is to manually turn the plate over in one production line or to load the material separately with two devices for coating on both sides, which is labor-intensive and labor-intensive. In addition, in order to ensure that the film can better adhere to the surface of the aluminum plate, the dust on the surface needs to be removed during cleaning to prevent the dust from affecting the coating effect. The existing coating device usually has a straight brush to sweep the surface, but this structure cannot remove dust well and there will still be residue.

[0004] If a device for coating an aluminum plate that does not require manual operation to flip the plate to replace the coating surface and can remove dust more thoroughly can be provided, the above technical problems can be better solved. Utility Model Content

[0008] A preferred solution is that a plurality of the first coating rollers are arranged in an array along the transport direction of the conveying mechanism, a modifier replenishing groove is provided below the first coating roller, and the first coating roller absorbs the modifier from the modifier replenishing groove while rotating.

[0009] A preferred solution is that the horizontal moving mechanism is arranged along a length direction perpendicular to the conveying mechanism, and at least one end of the horizontal moving mechanism is provided with an antioxidant replenishing groove cooperating with the second coating roller.

[0010] A preferred solution is that the cleaning mechanism further comprises an air duct assembly surrounding the circumference of the conveying mechanism, and the air duct assembly is located on a side of the plurality of vacuum adsorption ports close to the coating mechanism.

[0011] A preferred solution is that the air duct assembly is provided with bristles that cooperate with the aluminum plate, the bristles are distributed in an eight-shaped pattern on the air duct assembly, and the open ends of the bristles are away from the plurality of vacuum adsorption ports.

[0012] A preferred solution is that an air blowing port is further provided at one end of the air duct assembly away from the plurality of vacuum adsorption ports, and the air blowing port is connected to an external blower.

[0019] In this embodiment, a plurality of the first coating rollers 31 are arranged in an array along the transport direction of the conveying mechanism 1, and a modifier replenishing groove 34 is arranged below the first coating rollers 31. The first coating rollers 31 absorb the modifier from the modifier replenishing groove 34 while rotating. The lower end of the first coating roller 31 continuously contacts the modifier in the modifier replenishing groove 34, and then continuously absorbs the modifier and coats the modifier on the wire drawing surface of the aluminum plate while conveying the aluminum plate, so as to modify the surface and improve the bonding strength between the aluminum plate and the thermal conductive adhesive layer. The plurality of the first coating rollers 31 rotate synchronously with the conveying rollers of the conveying mechanism 1.

[0020] In this embodiment, the horizontal moving mechanism 33 is arranged perpendicular to the length direction of the conveying mechanism 1, and at least one end of the horizontal moving mechanism 33 is provided with an antioxidant replenishing groove 35 that cooperates with the second coating roller 32. By adopting the horizontally arranged horizontal moving mechanism 33, the second coating roller 32 is driven to apply the anti-oxidation film from both sides, and the antioxidant replenishing groove 35 is provided to replenish the second coating roller 32, so as to ensure that the coating work can be carried out for a long time.

[0021] In this embodiment, the cleaning mechanism 2 further includes an air duct component 22 surrounding the conveying mechanism 1, and the air duct component 22 is located on one side of the plurality of vacuum adsorption ports 21 close to the coating mechanism 3. The air duct component 22 is arranged so that the negative pressure generated by the vacuum adsorption ports 21 forms an airflow in the upstream direction of the conveying mechanism 1, thereby increasing the adsorption area, prolonging the adsorption time, and achieving the removal of dust as much as possible.

[0022] like Figures 2 to 4As shown, in this embodiment, the inner wall of the air duct component 22 is provided with bristles 23 matched with the aluminum plate, and the bristles 23 are distributed in an eight-shaped shape on the air duct component 22, and the open end of the bristles 23 is away from the plurality of vacuum adsorption ports 21.

The flexible clamping block is arranged at the movable end of the clamping cylinder. The clamping cylinder is arranged at the movable end of the lifting cylinder. The flexible clamping block cooperates with the side wall of the aluminum plate for clamping. The aluminum plate that has been coated is lifted by the clamping and lifting assembly 4.
