Description

Technical Field

[0001] This utility model belongs to the field of musical instrument manufacturing technology, specifically relating to a gluing fixture for musical instrument pegboards. Background Technology

[0002] Traditional Chinese musical instruments refer to unique musical instruments played by various ethnic groups around the world. Popular traditional Chinese musical instruments currently include the qin (a seven-stringed zither), zheng (a zither), xiao (a vertical bamboo flute), dizi (a transverse bamboo flute), suona (a double-reed horn), erhu (a two-stringed bowed instrument), pipa (a four-stringed lute), silk and bamboo instruments, and drums. During production, some traditional Chinese musical instruments have relatively large shells. Taking the pipa as an example, the pipa is a stringed instrument. The pipa has a headstock at the top, which generally protrudes upwards towards the soundboard. The soundboard has multiple sets of narrow, slightly upward-protruding horizontal frets called "frets." These frets divide the strings on the soundboard into many semitones. During production, a fret-arranging process is required, where multiple sets of frets are arranged parallel to each other on the soundboard, with each set of frets installed at a predetermined distance. When installing frets, they are generally pasted onto the soundboard by hand. Glue is applied to the bottom of the fret before it is attached. The strings are then plucked to check the pitch. If the pitch is incorrect, the fret needs to be repositioned. Each set of frets requires this process, and only one set can be pasted at a time. During pasting, the frets are prone to misalignment, making it difficult to ensure they are installed in the correct positions. Misalignment or uneven pasting necessitates rework and re-pasting. The assembly process is cumbersome, has low production efficiency, and requires a high level of skill and tonal sensitivity from the installer, making it unsuitable for large-scale production. Utility Model Content

[0003] The purpose of this utility model is to provide a tooling for applying glue to the vibrating parts of musical instruments, which aims to solve the problems of difficult vibrating operation, low efficiency, and unfavorable production in the production process of pipa.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a gluing fixture for musical instrument frets is provided, including a limiting fixture plate, a clearance groove is provided in the middle of the limiting fixture plate, a fret placement groove is provided on the first end face of the limiting fixture plate, and multiple sets of the fret placement grooves are arranged along the length direction of the side wall of the clearance groove, and the fret placement groove is used to place the first end of the fret.

[0005] In one possible implementation, the product placement slots are provided on both the left and right sidewalls of the clearance slot, and the product placement slots on the left and right sidewalls of the clearance slot are provided in a one-to-one correspondence.

[0006] In one possible implementation, the front end of the relief groove is provided with a headstock groove suitable for placing the headstock.

[0007] In one possible implementation, the sidewall of the clearance groove is provided with an installation groove, the bottom of the installation groove is provided with a limiting strip, and the product placement groove is provided on the first end face of the limiting strip away from the bottom of the installation groove.

[0008] In one possible implementation, the limiting strip is made of an elastic rubber material.

[0009] In one possible implementation, a clamping fixture is also provided, which is disposed in the relief groove and away from the item placement groove, and is used to clamp the item onto the panel.

[0010] In one possible implementation, the clamping fixture includes a clamping plate and a clamping handle, the clamping plate being disposed within the relief groove, and the clamping handle being disposed on the second end face of the clamping plate away from the product placement groove.

[0011] In one possible implementation, the clamping plate includes a first clamping plate, an intermediate buffer plate, and a second clamping plate arranged in sequence, with the clamping handle disposed on the second clamping plate.

[0012] In one possible implementation, the left and right sidewalls of the clamping plate match the left and right sidewalls of the relief groove.

[0013] In one possible implementation, the left and right edges of the limiting fixture plate coincide with the left and right edges of the panel.

[0014] The beneficial effects of the gluing fixture for musical instrument pegboards provided by this utility model are as follows:

[0015] Compared with existing technologies, this method uses a limiting fixture plate with a clearance groove that extends through the plate. A product placement groove is located on the first end face of the limiting fixture plate. Products are placed in this groove, which is positioned according to the spacing between the products. The groove is located on the side wall of the clearance groove, extending along its length. During product placement, the top end of each product is placed in the groove. After all products are placed, adhesive is applied to the bottom surface of each product. The panel is then placed face down on the bottom surface of the product, and pressure is applied to bond the panel to the product. Afterward, the panel with the product attached is removed from the limiting fixture plate. This allows for the installation of multiple sets of products at once, or even all products, improving the accuracy of product positioning and preventing misalignment or uneven adhesion. This increases work efficiency. After product installation, the strings are installed and tested. Attached Figure Description
