Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

Glass fiber is an inorganic non-metallic material with excellent performance, good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, and is often applied to electronic products due to the characteristics of higher structural strength, bending strength and easy processing, and compared with metal materials and other non-metallic materials, the glass fiber has low cost and light weight.

In the prior art, glass fiber boards are generally formed by fusing glass fibers and polymer resins and then forming sheet materials with a certain thickness through hot press molding, then cutting the sheet materials into a plurality of sheet materials with the same size as a workpiece, overlapping the plurality of cut sheet materials to the thickness of the workpiece and forming a workpiece prototype through hot press.

After the glass fiber plate is thermally laminated and molded, in order to match the size of the workpiece, CNC (Computerized Numerical Control) machining is required, that is, the surface of the molded glass fiber plate needs to be subjected to processes such as groove milling, hole drilling and the like. Although the glass fiber board has the advantages of high insulation property, high corrosion resistance and the like, the glass fiber board also has the defects of brittleness and poor wear resistance, so the structural strength of the glass fiber board is weakened, and the problems of cracking, breaking and the like can be caused by the processing.

In view of the above drawbacks, the present embodiment provides a composite laminate, which adopts a combination of glass fiber material and metal material, and solves the problem that the conventional glass fiber board may be broken during CNC processing. Specifically, the composite laminate is arranged as follows:

as shown in fig. 1 to 4, the present embodiment provides a composite laminated board 1, which includes a base board 11, a surface board 12, and an insert board 13, which are sequentially disposed, wherein the base board 11 is connected to the surface board 12, and the insert board 13 is sandwiched between the base board 11 and the surface board 12.

Specifically, when the base plate 11 and the surface plate 12 are subjected to the cladding process, the positions corresponding to the placement order of the respective plates are defined as references. Since the materials are stacked and pressed when the lamination is performed, the base layer plate 11 is usually the bottom-most plate, and the top layer plate 12 is the top-most plate.

The base plate 11 and the surface plate 12 are made of glass fiber, the embedded plate 13 is made of metal, a connecting through hole for connecting with parts can be formed on the embedded plate 13, and two ends of the connecting through hole penetrate through the base plate 11 and the surface plate 12.

In forming the composite laminate structure, an inner panel 13 made of a metal material is laminated between the base sheet 11 and the surface sheet 12 as a part of the inner structure. The composite laminate 1 has a predetermined cutting position, i.e., a cutting or drilling position required for CNC processing at a later stage, and the predetermined cutting position is used to form a connecting through-groove formed in a portion of the composite laminate 1 in which the inner panel 13 is embedded, that is, when drilling a surface of the composite laminate 1, for example, the drilling direction is first through the base sheet 11, then through the inner panel 13, and finally through the surface sheet 12 to form a through-type through-groove. Because the embedded plate 13 penetrates through the embedded plate 13 and the embedded plate 13 is made of metal, the structural stress at the position is basically born by the embedded plate 13, so that the stress of the base plate 11 and the surface plate 12 which are made of glass fiber materials is greatly reduced, and the effect of reinforcing the structural strength or transferring the stress is achieved.

Wherein, the logical groove of connecting specifically can be the through-hole, also can set up for the bar groove, other spare parts that specifically connect as required.

Specifically, when processing is performed, the product can be manufactured according to the following flow: selecting a glass fiber board sheet with proper thickness, cutting the glass fiber board sheet by using a die according to the shape and the size of the outline to be processed to obtain an original base plate 11, then positioning an inner embedded plate 13 on the surface of the base plate 11, determining the positioning position according to the position of the composite laminated plate 1 needing CNC processing in the later period, ensuring the position of the inner embedded plate 13 to be unchanged after the positioning of the inner embedded plate is finished, and further coating a surface plate 12 on the surface of the inner embedded plate.

The whole process is carried out through the laminating jig, and the laminating jig is provided with a lower cover plate 2 and an upper cover plate 3, under the ordinary condition, the position of the lower cover plate 2 is unchanged, the base plate 11 is firstly placed on the lower cover plate 2, then the inner embedded plates 13 and the surface plate 12 are placed one by one, and finally the upper cover plate 3 is pressed to form the integral structure of the composite laminated plate 1.

This combined type laminated board 1 passes through base plate 11, surface plate 12 and interior panel 13 form this combined type laminated board 1 structure jointly, wherein, the material of base plate 11 and surface plate 12 is glass fiber, embedded board 13 is embedded between base plate 11 and surface plate 12, and the material of interior panel 13 is the metal, through this kind of structural setting, make embedded board 13 form the position that is used for cutting of laminated board, processing such as the drilling milling flutes to the laminated board can go on interior panel 13, realized promptly through metal substrate reinforcement structure, thereby avoided cutting on the glass fiber board and probably caused the cracked problem of glass fiber board to appear, product design demand has been satisfied.

Due to the materials of the base plate 11 and the surface plate 12 and the positional relationship among the base plate 11, the surface plate 12 and the inner panel 13, the present embodiment uses a hot pressing method to integrally form the three. Because the glass fiber board can become soft in a high-temperature state, the embedded board 13 can be better positioned inside by the hot pressing mode, and meanwhile, the base layer board 11 and the surface layer board 12 can be more firmly fixed.

Furthermore, a plurality of first positioning holes 111 are formed in the base plate 11, a plurality of second positioning holes 121 corresponding to the positions and the number of the first positioning holes 111 are formed in the surface plate 12, and the base plate 11 and the surface plate 12 are jointly inserted into the first positioning holes 111 and the second positioning holes 121 through the mold positioning bumps 21 for positioning. Since the lamination by jig is required, it is necessary to secure the positions of the base plate 11, the surface plate 12 and the inner panel 13 in the lamination process. The jig surface may be provided with a mold positioning projection 21, and the mold positioning projection 21 is inserted into the first positioning hole 111 of the base plate 11 and the second positioning hole 121 of the surface plate 12, thereby ensuring the position fixation.

In order to ensure the flat structure of the laminated board formed after lamination, in the embodiment, the size of the base board 11 and the size of the surface board 12 are the same, and the size of the inner embedded board 13 is smaller than that of the base board 11 and the surface board 12, on one hand, the inner embedded board 13 mainly plays a role of providing a connecting position, so that the preset cutting position of the laminated board can be covered, and on the other hand, if the outer edge of the inner embedded board 13 exceeds the base board 11 and the surface board 12, the edge cutting is more troublesome compared with the glass fiber board.

In most cases, a predetermined cutting position of the laminate sheet is limited, and for example, a plurality of connecting through grooves are required along the edge portions of the surface of the laminate sheet, so that the inner panel 13 is provided to include a plurality of connecting pieces, all of which are arranged at intervals between the base sheet 11 and the skin sheet 12. The arrangement of the plurality of connecting sheets to form the inner panel 13 can further enlarge the area covered by the inner panel 13 and improve the flexibility of the arrangement of the preset cutting positions of the composite laminated board 1, and can also be arranged at a plurality of positions when the cutting positions are relatively dispersed, so that the inner panel 13 is reduced as much as possible, and the phenomenon that the arrangement of the inner panel is too much and the advantages of the glass fiber board are adversely affected is avoided.

For the positioning operation of the inner panel 13 within the composite laminate 1, in some implementations, the composite laminate 1 may further include a middle layer panel 14, the middle layer panel 14 being positioned between the base layer panel 11 and the top layer panel 12, the middle layer panel 14 having a positioning groove 141 formed thereon, and the inner panel 13 being positioned within the positioning groove 141. The middle layer 14 is also made of a glass fiber board and is used to provide a positioning groove 141 for placing the inner panel 13, so that the inner panel 13 is not moved during the pressing process after being placed.

With the intermediate layer sheet 14, the composite laminate 1 is processed in such a manner that the intermediate layer sheet 14 is placed after the base layer sheet 11 is placed. At this time, the positioning groove 141 is formed on the middle layer plate 14, and the inner panel 13 is placed at the position of the positioning groove 141, thereby ensuring that the inner panel 13 does not slip when the surface layer plate 12 is further coated.

In order to make the positioning effect better, the shape of the positioning groove 141 matches with the outer contour shape of the inset plate 13, and the shape of the positioning groove 141 can also provide a placement guide for an operator, which can further accelerate the assembly efficiency.

Because the glass fiber plate is thin and fragile, the thickness of the embedded plate 13 is the same as that of the middle layer plate 14, so that the base layer plate 11 and the surface layer plate 12 are respectively attached to the surface of the middle layer plate 14 and the surface of the embedded plate 13 in the hot pressing process, and the risk of cracks caused by overlarge local stress due to the fact that the height is different is avoided.

When the composite laminated board 1 is applied, due to the characteristics of sound absorption, sound insulation, heat insulation, environmental protection, flame retardance and the like, the composite laminated board is applied to a soft package base layer, and the outside is coated with cloth art, leather and the like. Accordingly, in response to the characteristics of the composite laminated board 1, the present embodiment further provides a product support, which includes the composite laminated board 1, as shown in fig. 2 to 4.

The embedded plate 13 of the composite laminated plate 1 can be applied to the positions where edges of the product support are scratched or the positions where the edges are easy to collide, so that the connection effect is ensured, and cracks caused by large acting force on the structure of the laminated plate are avoided.

In an achievable manner, the product support may comprise a support member 5, the support member 5 being connected to the composite laminate 1 at the connecting channel. The support member 5 extends away from the composite laminate 1 such that a product placement space is formed between the support member 5 and the composite laminate 1. For example, the composite laminated board 1 can be applied to a leather sheath keyboard of an electronic product 4, the problem of screw hole edge fracture on a board can not be caused in the sliding, overturning and falling processes, and the strength requirement of product design is met.

Of course, the composite laminated board 1 may be applied to other embodiments, and as long as the problem that the glass fiber material is applied and the position of the board is stressed is solved, the problem can be avoided by the structure of the composite laminated board 1 provided in this embodiment.
