Composite Panel Device and Its Manufacturing Method

Abstract

A composite sheet metal assembly and its manufacturing method are disclosed. The assembly comprises a core board with two opposing surfaces and two metal plate assemblies. Each metal plate assembly includes a metal component and a metal sheet adhered to their respective surfaces, and a first adhesive layer and a second adhesive layer for bonding. Each metal component has a bonding portion adhered between the respective metal sheet and the respective surface. Each first adhesive layer covers the respective surface, and each metal component and each metal sheet are bonded to their respective first adhesive layer. Each second adhesive layer is bonded between the respective bonding portion and the respective metal sheet. By directly attaching the metal sheet to the metal component and together with it to the same core board, the manufacturing process eliminates the need for splicing, offering the advantage of simplified manufacturing.

The material has a joining plate portion attached to each of the bonding plate portions, and a body plate portion protruding from each of the bonding plate portions and attached to each of the plate surfaces. Each metal plate includes a plate width in the same direction as the core plate width. Each first adhesive layer covers each of the plate surfaces and is bonded between each of the metal plates and each of the plate surfaces, and is bonded between the body plate portion and each of the plate surfaces of each of the metal plates. Each second adhesive layer is bonded between each of the bonding plate portions and each of the bonding plate portions. The core plate width is greater than the width of each of the plate components and greater than the width of each of the plate portions.

2. The composite panel device as claimed in claim 1, wherein, The core board also includes a core board length of not less than 1.8 meters and not more than 10 meters, and the width of each core board is not less than 0.9 meters and not more than 1.5 meters.

3. The composite panel apparatus as described in claim 1, wherein, The core board and the metal plate groups are stacked along a stacking direction, and the bonding plate portion of each metal plate group does not overlap with the bonding plate portion of another metal plate group in that stacking direction.

4. The composite panel apparatus as claimed in claim 1, wherein, The core board includes a side surface connected between the board surfaces, each board surface includes a concave portion recessed into the other board surface and spaced apart from the side surface, and each bonding portion is attached to the respective concave portion.

5. A method for manufacturing a composite board apparatus, comprising: Step (A): conveying a mother board along a conveying direction; Step (B): conveying two first adhesive tapes along the conveying direction, such that the first adhesive tapes are respectively disposed on two opposing mother board surfaces of the mother board; Step (C): conveying two first metal strips along the conveying direction, such that the first metal strips are respectively disposed on the surfaces of the first adhesive tapes, wherein a first width of each first metal strip is less than a mother board width of the mother board; Step (D): conveying two second adhesive tapes along the conveying direction; Step (E): conveying two second metal strips along the conveying direction, such that each second metal strip is partially overlapped on the surface of a respective first metal strip in a width direction transverse to the conveying direction through the second adhesive tapes, wherein each second adhesive tape is located between the respective second metal strips and the respective first metal strips, and a second width of each second metal strip is less than the mother board width of the mother board; Step (F): Heating to melt each of the first adhesive tape and each of the second adhesive tape to form an adhesive, and pressing the mother plate, the first adhesive tape, the first metal strip, the second adhesive tape and the second metal strip together; and Step (G): Cutting the mother plate, the first adhesive tape, the first metal strip, the second adhesive tape and the second metal strip to obtain a composite board device.

6. The method of manufacturing the composite sheet apparatus as claimed in claim 5 further includes a step (H) in which the mother plate, the first metal strips, the second metal strips are cooled, and the adhesive formed after each of the first adhesive strips is heated and melted is cooled, and the adhesive formed after each of the second adhesive strips is cooled.

7. The method for manufacturing the composite panel apparatus as described in claim 6, wherein, The first conveyor belt, the first metal belt, the second conveyor belt, and the second metal belt are conveyed by several rollers.

8. The method for manufacturing the composite panel apparatus as described in claim 6, wherein, Step (F) involves heating each of the first adhesive tapes and each of the second adhesive tapes with at least one heating roller to form an adhesive, and pressing the motherboard, the first adhesive tapes, the first metal strips, the second adhesive tapes and the second metal strips together. Step (H) involves cooling the motherboard, the first metal strips and the second metal strips with at least one cooling roller, and cooling the adhesive formed by the melting of each of the first adhesive tapes and the adhesive formed by the melting of each of the second adhesive tapes.

9. The method for manufacturing the composite panel apparatus as described in claim 7, wherein, Each of these rollers rotates at a speed of 2 to 4 meters per minute.
