Guitar double-sided board adhesion method

Abstract

The invention relates to the technical field of guitar manufacturing, and discloses a guitar double-sided board adhesion method. The guitar double-sided board adhesion method comprises the following specific steps that S1, a cellular net is put on a clean base plate, the appropriate amount of imported wood glue is squeezed onto the upper right corner of the base plate, a plush roller brush slowlyrolls to dip the wood glue, and the imported wood glue can be squeezed onto the base plate in a small-amount multi-frequency mode; and S2, after the plush roller brush is uniformly covered with the wood glue, the roller brush slowly rolls on one surface of the cellular net for glue smearing at the constant speed, glue paths are overlapped by 1-2 cm, during glue smearing, the roller brush smears the glue in the same direction till the whole adhesion surface of the cellular net is covered with the glue, the cellular net is protected from being damaged in the glue smearing process, and the plushroller brush needs to be replaced in time. According to the guitar double-sided board adhesion method, the phenomenon that a cellular layer is blocked due to the fact that the adhesion strength is notenough or the amount of the glue is too large can be avoided, in addition, the phenomenon that after several cellular nets are continuously processed, surface drying of the glue starts to occur can be avoided, and the guitar double-sided board adhesion method is suitable for batch guitar double-sided board adhesion continuous operation.

Description

technical field [0001] The invention relates to the technical field of guitar manufacturing, in particular to a method for bonding double panels of a guitar. Background technique [0002] At present, the high-end guitar panels are equipped with white pine or red pine solid wood panels. In order to increase the volume of the guitar, it is necessary to improve the vibration efficiency of the panel. The general tendency is to make the panel thinner and thinner, but this will cause the structure of the guitar to become unstable. , the panel is prone to collapse. Therefore, manufacturers began to look for high-strength and light panel materials, and the double-panel guitar was developed under this background. The basic structure of the double panel is composed of two pieces of white pine or red pine with a thickness of about 0.6mm and a Nomex honeycomb with a thickness of about 0.8mm sandwiched between them ( figure 1 )composition. Nomex (NOMEX) is the trade name registered by...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a double-sided guitar bonding method, which can avoid the phenomenon of insufficient bonding strength or too much glue blocking the honeycomb layer, and can avoid the glue starting to appear after several pieces of continuous operation. Dry phenomenon, so it is suitable for continuous operation of double-sided bonding of guitars in batches, etc. It solves the problem that the thickness of the adhesive film on the glass plane is difficult to grasp, and the thickness of the adhesive film on the plane is uneven, which easily leads to insufficient bonding strength. Or too much glue blocks the honeycomb layer and each time the honeycomb layer is glued, it needs to be reapplied. After several pieces of continuous operation, the glue starts to dry, and the glass surface needs to be cleaned and reapplied. It is not suitable for batch continuous operation.
