Detailed Description
As shown in figure 1, the invention provides a method for manufacturing a finger board of a musical instrument with fixed position by using all carbon fibers, which comprises the following steps:
s1: cleaning the mould and polishing the mould with mould release wax;
s2: using a plurality of layers of carbon fiber dry cloth to be stacked into a layer, and putting the layer into a dipping disc to be dipped;
s3: pressing the laying layer, the demolding cloth, the flow guide net and the vacuum bag into a mold in sequence to obtain a finger plate blank;
s4: mounting a fixed beam and an opening wire groove;
s5: and installing the product wire and closing up.
Specifically, the mold is prepared first, and the previous preparation is made. Since the required molds for various musical instruments are different, here, for example, a guitar fingerboard, a soft gauze is used to clean the mold surface, then a tool is used to clean the mold surface, and a waxing tool is used to apply a release wax to the entire mold surface so that the release wax is uniformly adhered to the mold surface. If necessary, a hot air gun can be used for heating so as to ensure that the demolding wax is uniformly attached to the surface of the mold.
In a preferred embodiment of the invention, 9 layers of dry carbon fibre cloth are used to form the lay-up and the surface layer is placed uppermost, wherein before placing the lay-up into the mould, the lay-up is first placed into a dip pan and then the formulated epoxy resin is poured onto the lay-up for saturation, the saturation time being about 2 hours. Here, the method of impregnating the laminate with the epoxy resin may be replaced with a method of impregnating the laminate with a glue or a paste.
In other embodiments, 7 or 8 layers may be used, with a typical carbon fiber layer selection ranging from 5-15 layers. The adopted carbon fiber dry cloth is 3K200G bidirectional dry cloth, and in other embodiments, other materials can be adopted for the carbon fiber dry cloth.
In a preferred embodiment of the present invention, as shown in fig. 2, the material for making the fingerboard of the all-carbon fiber musical instrument comprises the following components: laying layers 2, demoulding cloth 3, a flow guide net 4, a vacuum bag 5 and a mould 1. In the manufacturing process, the laying layer 2, the demoulding cloth 3, the flow guide net 4 and the vacuum bag 5 are pressed into the mould 1 in sequence, then the drainage pipe 6 is connected between the flow guide net 4 and the vacuum bag 5, and the vacuum bag 5 is covered on the mould 1 by using a sealing device 7, wherein the surface layer of the laying layer 2 is placed downwards (because the grain of the surface layer looks clearer and smoother), and the grain of the carbon fiber is kept neat, so that the appearance is more beautiful and beautiful, wherein the sealing device 7 can be sealant, other adhesives or other sealing modes.
As shown in fig. 3, fig. 3 is a schematic view of a vacuum flow guide connection. In FIG. 3, the draft tube 22 includes two sections, a first section and a second section. One end of the first pipe section is connected with the mould, the other end is connected with the inlet of the shunt tank 23, the outlet of the shunt tank 23 is connected with the vacuum pump, and a throttle valve 24 is arranged on the second pipe section of the drainage pipe 22 connected between the shunt tank and the vacuum pump and is arranged close to the shunt tank for keeping the pressure in the vacuum bag 5 in fig. 2 stable. In operation, the vacuum pump 25 is activated to evacuate air and excess glue from the vacuum bag 5 of fig. 2. If there is a leak, it may be necessary to make a leak with sealant or other material, or by other means, to seal. And after no air leakage is confirmed, closing the throttle valve and waiting for the epoxy resin to be cured. It should be noted that the time for curing the different epoxy resins varies, typically between 1 and 1.5 hours.
In a preferred embodiment of the present invention, after the fingerboard blank is demolded, the fingerboard blank needs to be trimmed and surface-treated, specifically, after the fingerboard blank is demolded, the fingerboard blank is cut and the excess edges are removed by using a suitable tool, so that the thickness of the fingerboard blank is about 2mm, and the general thickness can be 1.5-3mm, but other suitable thicknesses can be adopted.
In a preferred embodiment of the present invention, the fingerboard blank is further processed, for example, the fingerboard blank is dewaxed to clean the fingerboard blank and coated with epoxy resin, and after the epoxy resin is solidified, the fingerboard blank is polished to make the surface of the fingerboard blank smooth.
In a preferred embodiment of the present invention, further, a UV coating is sprayed on the surface of the fingerboard blank and cured by UV light, which is completed under a shading condition, and the finished fingerboard surface cannot be polished again. In other embodiments, the surface of the fingerboard blank can be painted.

The first fixing beam 42 is placed at the middle position of the back of the fingerboard blank 41, and the second fixing beams 43 are disposed at both sides of the back of the fingerboard blank 41 as shown in fig. 4. The first fixing beam 42 and the second fixing beam 43 are placed in the same length direction, and the first fixing beam 42 and the second fixing beam 43 are temporarily fixed together with the back of the fingerboard blank 41 by a fixing device, such as glue. The first fixing beam 42 and the second fixing beam 43 may be sectional materials and are spaced apart at a certain distance, and the first fixing beam 42 and the second fixing beam 43 have sizes of 4-12mm and 1X5mm, respectively. In other embodiments, other dimensions can be used, and any profile that meets the required specifications can be used.
After the above-described fixing, a tool, such as a saw, is then used to saw a fret slot for mounting a fret, transversely along the transverse direction of the first fixing beam 42 and the second fixing beam 43. It should be noted that, during the sawing process, it is necessary to ensure that the outer edge of the saw kerf is kept at a certain distance, preferably 2mm, from the work table surface, so that the finger plate blank can be sawed and the finger plate cannot be integrally sawed, thereby achieving a good effect.
In a preferred embodiment of the present invention, the mounting the filament and closing further comprises: pressing metal product wires into the carbon fiber finger plate, brushing a layer of epoxy resin on the back of the finger plate to fix the product wires, sealing gaps between the product wires and the product wire grooves by using carbon fiber sheets, installing sound points on the finger plate, polishing corners and polishing.
