Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of guitars, and in particular to a modular guitar installation structure and a production process thereof. Background Art
[0002] Traditional guitar manufacturing mostly uses an integral gluing process, which has the following significant defects:
[0003] Low production efficiency: Each component (such as the top, side panels, and back panel) needs to be manually glued piece by piece, which relies on the experience of technicians. The assembly accuracy (such as the positioning of the sound beam) is poor. The assembly of a single guitar takes a long time, which makes it difficult to meet the needs of large-scale production.
[0004] The positioning of the top, side panels, and head and tail wood blocks (head and tail panels) lacks a unified benchmark, requiring repeated adjustments and alignment. Poor side panel height consistency can easily lead to cabinet asymmetry or unstable acoustic performance, and the quality of the finished product is highly dependent on the craftsman's proficiency.
[0005] High degree of process coupling and high rework costs:
[0006] The bonding of various components (such as panels, side panels, and header and foot panels) must be performed simultaneously, and adjustments are difficult to make after the glue has cured. If a component is misaligned, destructive removal may be necessary, increasing time and material loss.
[0007] Therefore, how to provide a guitar modular installation structure and its production process with high-precision modular assembly and industrial production to solve the low efficiency and poor installation accuracy in traditional manufacturing is one of the technical problems that need to be solved urgently in this field. Summary of the Invention
[0008] The purpose of the present invention is to provide a guitar modular installation structure and a production process thereof.
[0009] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:
[0010] The present invention provides a modular guitar installation structure, comprising: a panel, a panel bracing structure, side panels, a frame structure, a back panel bracing structure, a back panel and a neck;
[0011] The frame structure includes a front frame, a back frame, a tail plate and a head plate; the front frame and the back frame are both provided with a panel groove for installing the panel and a back plate groove for the back plate, and the panel groove is consistent in size and shape with the back plate groove. At the same time, the front frame and the back frame are both provided with side plate grooves for installing the side plates.
[0012] Furthermore, the front frame and the back frame are also provided with a tail plate positioning mechanism and a head plate positioning mechanism.
[0013] Furthermore, the tail plate is provided with a tail plate bolt hole that cooperates with the tail plate positioning mechanism; the head plate is provided with a head plate bolt hole that cooperates with the head plate positioning mechanism and a neck mounting hole for mounting the neck.
[0014] Furthermore, the front frame and the back frame have several groups of buckles evenly and symmetrically arranged on the inner edges, and the buckles are used to fix the panel force wood structure and the back panel force wood structure.
[0015] Furthermore, the buckle corresponds to the edge structure position of the reinforced wood structure and has the same size and shape.
[0016] Furthermore, the side panels include a pair of side panels symmetrically installed in the grooves of the side panels of the frame structure. The side panels are located between the front panel and the back panel to form the side profile of the guitar.
[0017] Furthermore, the panel groove is a continuous or segmented groove opened along the edge of the frame, and its shape and depth are designed to accurately accommodate and position the edge of the panel.
[0018] Furthermore, the side panel grooves are located at both side edges of the frame structure, adjacent to or continuous with the panel grooves, and their shape and depth are designed to accurately accommodate and position the upper and lower edges of the side panels.
[0019] The present invention provides a production process for a modular guitar mounting structure, comprising the following steps:
[0020] S1: Material preparation: Cut out the blanks of the top, top bracing structure, side panels, frame structure, back bracing structure, back panel and neck according to the design drawings and size requirements;
[0021] S2: Panel pretreatment (veneer bracing wood);
[0022] S3: Install the front frame and the head and tail panels for positioning;
[0023] S4: Install side panels;
[0024] S5: Install the back frame;
[0025] S6: Install backboard bracing and backboard;
[0026] S7: Complete assembly (final tightening and installation of the neck).
[0027] Beneficial effects of the present invention:
[0028] The modular guitar mounting structure and production process provided by this invention achieve the following breakthrough advantages: 1. Structural: The panel and side panel grooves integrated into the frame structure form a mechanical positioning reference, ensuring zero deviation in the edge positions of the panel, back panel, and side panels. The tail panel positioning mechanism and head panel positioning mechanism cooperate with corresponding holes to achieve precise axial and radial positioning of the head and tail panels, completely eliminating the cumulative errors of traditional processes. The frame structure serves as the core skeleton, with the panel and back panels clamped by the front and back frames and connected in both directions by a bracing structure, forming a "sandwich"-like deformation-resistant structure, significantly improving the cabinet's resistance to string tension.
[0029] 2. Process level: Assembly efficiency is greatly improved: Step-by-step decoupled assembly: First, establish the core positioning reference through step S3 (installing the front frame + bolting the head and tail panels); then, in step S4 (installing the side panels), the "grooving + gluing the head and tail panels" actions are completed simultaneously. This single-step operation replaces traditional multi-station collaboration, significantly reducing working hours. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Example 1
[0037] like Figure 1 As shown: The present invention provides a modular guitar installation structure, which includes: a panel 10, a panel bracing structure 20, a side panel 30, a frame structure 40, a back panel bracing structure 50, a back panel 60 and a neck 70;
[0038] The frame structure 40 includes a front frame 41, a back frame 42, a tail plate 43 and a head plate 44; the front frame 41 and the back frame 42 are both provided with a panel groove 411 for installing the panel 10 and a back plate groove for the back plate 50, and the panel groove is consistent in size and shape with the back plate groove. At the same time, the front frame 41 and the back frame 42 are both provided with a side plate groove 412 for installing the side plate 30, and the front frame 41 and the back frame 42 are also provided with a tail plate positioning mechanism 413 and a head plate positioning mechanism 414; the tail plate 43 is provided with a tail plate bolt hole 431 that cooperates with the tail plate positioning mechanism 413; the head plate 44 is provided with a head plate bolt hole 441 that cooperates with the head plate positioning mechanism 414 and a neck mounting hole 442 for mounting the neck 60.
[0039] The edge of the panel 10 is embedded in the panel groove 411 for positioning, and the edges of the side panels 30 are respectively embedded in the side panel grooves 412 of the front frame 41 and the back frame 42 for positioning. The tail panel 43 is positioned by being mounted on the tail panel positioning mechanism 413 through the tail panel bolt hole 431, and the head panel 44 is positioned by being mounted on the head panel positioning mechanism 414 through the head panel bolt hole 441. The panel force wood structure 20 is fixedly set on the front frame.
[0040] Furthermore, the front and back frames 41 and 42 have several sets of clips symmetrically arranged on their inner edges. These clips are used to secure the panel bracing structure 20 and the back panel bracing structure 50. These clips correspond to the structural positions of the bracing structures' edges and are identical in size and shape. During use, the bracing structures' edges can be firmly clamped in the corresponding clip positions. The panel bracing structure 20 and the back panel bracing structure 50 can be pre-attached to the panel 10 and back panel 60, and then installed in sequence with the corresponding clips on the frame structure 40.
[0041] The side panels 30 include a pair of side panels symmetrically mounted in the side panel grooves of the frame structure 40 . The side panels 30 are located between the panel 10 and the back panel 50 , forming the side profile of the guitar.
[0042] The back panel 60 constitutes the rear surface of the guitar; the edge of the back panel 60 is embedded in the back panel groove for positioning.
[0043] The neck 70 is fixed to the headboard 44 through the neck mounting hole 442;
[0044] The top 10 is typically made of high-quality acoustic wood (such as spruce or cedar) and forms the front surface (soundboard) of the guitar. It is the primary vibrating sound-producing component. A wood structure is bonded to its inner side (i.e., the inner side of the guitar) to enhance structural strength and sound conduction.
[0045] The bracing structure is located inside the guitar's interior and is typically composed of a mesh of bracing wood interwoven together. The bracing structure includes a panel bracing structure 20 and a back panel bracing structure 50, both of which are connected and fixed to the front frame (41) and the back frame (42), respectively (e.g., by bonding and mortising), forming an internal support network for supporting the panel 10 and the back panel 50, transmitting vibrations, and maintaining the shape of the guitar body, which significantly affects the tone and volume.
[0046] The side panels 30 are usually made of hardwood (such as rosewood, mahogany, etc.) bent into the side profile of the guitar. They are connected between the panel (10) and the back panel (50) to form the side profile of the guitar (i.e., the waist and neck connection part).
[0047] The frame structure 40 serves as the core support, positioning framework, and connection hub of the entire guitar box, and is the key to achieving modular installation. It specifically includes:
[0048] Front frame 41: A rigid structural member (usually made of hardwood or high-stability composite material) fixedly mounted on the inside of the panel 10. Its design has the following core features:
[0049] Panel groove 411: A continuous or segmented groove opened along the edge of the frame, the shape and depth of which are designed to accurately accommodate and position the edge of the panel 10. Once the panel 10 is inserted into this groove, its position is determined.
[0050] Side panel grooves 412 are located on either side of the frame structure 41, adjacent to or continuous with the panel grooves 411. Their shape and depth are designed to precisely accommodate and position the upper and lower edges of the side panels 30. Once the upper and lower edges of the side panels 30 are inserted into these grooves, their height and horizontal position relative to the front panel 10 and back panel 60 are precisely constrained.
[0051] Back frame 42: A rigid structural member corresponding to the front frame 41, fixedly mounted on the inner side of the back plate 50. The inner side of the back plate bracing structure 50 is usually bonded.
[0052] Tail plate 43: This hardwood block, located at the rear end of the guitar case, connects and secures the rear ends of the two side panels 30. It features tail plate bolt holes 431 at the top and bottom, respectively. These holes are designed to precisely mate with tail plate positioning mechanisms 413 (typically through-holes or threaded holes) on the front and back frames 41 and 42. By interlocking these holes and bolts, the tail plate 43 is precisely positioned relative to the frame structure 40.
[0053] Headboard 44: A hardwood block located at the front end of the guitar body, it connects to the front ends of the side panels 30 and serves as the mounting base for the neck 60. Headboard bolt holes 441 are defined on the top and bottom of the headboard. Furthermore, these headboard bolt holes 441 precisely mate with holes (through or threaded) in the headboard positioning mechanism 414 on the front and back frames 41, 42, to precisely locate the headboard 44 relative to the frame structure 40.
[0054] Neck mounting hole 442: It is usually a threaded hole or a through hole (matching a nut), used to firmly mount and fix the neck 70 on the head plate 44 through fasteners such as screws or bolts.
[0055] Backboard 50: usually made of acoustic wood (such as rosewood, maple, etc.) that matches or complements the panel, forming the back surface of the guitar. Its inner side will be bonded with back strength wood and covered on the back frame 42 during the process.
[0056] Neck 70: the neck head of guitar, on which string knobs are installed. It is fixedly installed on the head plate 44 by passing the fastener (such as screw) of the neck mounting hole 442 on the head plate 44.
[0057] Example 2
[0058] like Figure 1-6 As shown: Based on the structure described in Example 1, this embodiment provides a production process for a modular guitar installation structure, the steps are as follows:
[0059] S1: Material preparation
[0060] According to the design drawings and size requirements, the blanks of the panel 10, the side panels 30 and the back panel 50 are cut out respectively. The blanks need to be properly dried and preliminarily treated on the surface.
[0061] S2: Panel pretreatment (veneer wood)
[0062] On the inside of the panel 10 (the side that will face the interior of the guitar case), a suitable adhesive is used to bond the panel's bracing structure 20, as required by the design. This serves to enhance the panel's rigidity and sound transmission. After bonding, pressurize and secure the panel until the glue cures.
[0063] S3: Install the front frame and the head and tail panels (preliminary positioning)
[0064] Place the front frame 41 inside the panel 10 that has completed step S2. Carefully align the panel 10 to ensure that the edges are fully and accurately embedded in the panel grooves 411 on the front frame 41. At the same time, the edges of the panel bracing structure 20 are also accurately embedded in the clips of the front frame 41. Then use adhesive to firmly bond / fix the front frame 41 to the inside of the panel 10.
[0065] Insert the tail plate 43 through the tail plate bolt holes 431 and onto the tail plate positioning mechanism 413 at the rear end of the front frame 41. At this point, simply use your hands or simple tools (such as washers or temporary nuts) to preliminarily position the tail plate 43 on the bolts 413 to prevent it from falling off or moving excessively, but do not fully tighten it.
[0066] Similarly, the head plate 44 is sleeved onto the head plate positioning mechanism 414 at the head end of the front frame 41 through the head plate bolt holes 441 opened thereon. Similarly, only preliminary positioning is performed.
[0067] S4: Install the side panels
[0068] Take the side panels 30. Carefully and completely insert the top edge of the first side panel (i.e., the side closest to the panel / front frame) into the side panel groove 412 on the corresponding side of the front frame 41. Make sure that the side panel 30 fits well in the groove 412 along its entire length.
[0069] At the same time, the head end of the side panel 30 (close to the neck end) is tightly fitted to the corresponding side surface of the head panel 44 and is bonded and fixed using an adhesive.
[0070] The tail end of the side panel 30 (close to the bottom end of the guitar) is tightly fitted to the corresponding side surface of the tail panel 43 and fixed with adhesive.
[0071] Repeat the above process to install the side panel 30 on the other side, and also ensure that its upper edge is embedded in the side panel groove 412 on the other side.
[0072] At this point, through the cooperation of the panel grooves 411, the side panel grooves 412, and the head and tail panel positioning screws (414 / 413), the side panels 30 are precisely positioned and constrained in three dimensions (height, horizontal position, and head and tail positions). They are then bonded to the head and tail panels to form the initial box outline. The lower edge of the side panel 30 (near the back panel) is now free.
[0073] S5: Install the back frame
[0074] The back frame 42 is placed inside the preliminary box structure (i.e., the side to be covered by the back panel) composed of the panel 10, front frame 41, side panels 30, head panel 44, and tail panel 43 installed in steps S1-S4.
[0075] Adjust the position of the back frame 42 so that the lower edges of the side panels 30 are carefully and completely embedded in the side panel grooves on the corresponding sides of the back frame 42. Ensure that the side panels 30 fit snugly into the grooves along their entire length. Simultaneously, secure the tail panel 43 and the head panel 44 to the corresponding head and tail panel positioning mechanisms on the back frame 42 using the tail panel bolt holes located below them, and the head panel 44 using the head panel bolt holes located below them.
[0076] S6: Install the back support wood and backboard
[0077] Adhesive is used to secure the back panel bracing structure 50 to the inner side of the fixed back frame 42 (i.e., the side facing the interior of the box) according to design requirements. The back panel bracing is typically simple horizontal or grid-like wood strips used to support and reinforce the back panel 60. After bonding, pressure is applied to allow curing.
[0078] Drape the back panel 60 blank over the entire back contour formed by the lower edges of the side panels 30, the back of the head panel 44, the back of the tail panel 43, and the outer edge of the back frame 42. Carefully align the edges to ensure they are aligned. Fit the blank precisely into the panel grooves on the back frame 42, while also fitting the edges of the back panel bracing 50 precisely into the clips on the back frame 42. Then, use adhesive to securely bond / fix the back frame 42 to the inside of the back panel 60.
[0079] S7: Complete assembly (final tightening and installing the neck)
[0080] After the box glue is cured, remove the clamp.
[0081] Perform a final tightening of the bolts initially positioned in step S3. Use a suitable tool (such as a wrench) to tighten the nuts on the tail plate positioning mechanism 413 (or directly tighten the bolts, depending on the specific design) to securely fasten the tail plate 43 to the front frame 41. Similarly, tighten the nuts (or bolts) on the head plate positioning mechanism 414 to securely fasten the head plate 44 to the front frame 41. This step eliminates the pre-tightening gap and ensures that the connection between the head and tail plates and the frame meets the designed strength and precision.
[0082] Finally, the neck 70 is securely mounted and fixed to the headboard 44 using fasteners such as screws or bolts through the neck mounting hole 442 .
[0083] So far, if Figure 6 Shown: The main modular assembly of the guitar body (top, sides, back, internal frame) and neck is completed.
[0084] The modular guitar mounting structure and production process provided by this invention achieve the following breakthrough advantages: 1. Structural: The panel and side panel grooves integrated into the frame structure form a mechanical positioning reference, ensuring zero deviation in the edge positions of the panel, back panel, and side panels. The tail panel positioning mechanism and head panel positioning mechanism cooperate with corresponding holes to achieve precise axial and radial positioning of the head and tail panels, completely eliminating the cumulative errors of traditional processes. The frame structure serves as the core skeleton, with the panel and back panels clamped by the front and back frames and connected in both directions by a bracing structure, forming a "sandwich"-like deformation-resistant structure, significantly improving the cabinet's resistance to string tension.
[0085] 2. Process level: Assembly efficiency is greatly improved: Step-by-step decoupled assembly: First, establish the core positioning reference through step S3 (installing the front frame + bolting the head and tail panels); then, in step S4 (installing the side panels), the "grooving + gluing the head and tail panels" actions are completed simultaneously. This single-step operation replaces traditional multi-station collaboration, significantly reducing working hours.
[0086] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
