Description

Technical Field

[0001] This invention belongs to the field of parts processing and assembly technology, specifically relating to an integrated assembly process for the layered glue application of magnets on a solid wood cover plate for a game console. Background Technology

[0002] Currently, the assembly of solid wood cover magnets for game consoles generally uses plastic limiting molds to fix solid wood workpieces, combined with single-point glue valves to dispense glue at specific points. Automated equipment is used to complete the placement and pressing assembly of magnets, thus addressing the problems of large dimensional tolerances in solid wood substrates and poor precision in manual magnet assembly, and basically realizing automated production of magnet bonding for solid wood workpieces.

[0003] However, the existing assembly process only uses a single-layer, single-point gluing mode, which still has many defects in actual mass production:

[0004] 1. Insufficient precision in controlling the amount of glue applied can easily lead to insufficient glue, causing the magnets to fall off, or glue overflow to contaminate the solid wood board surface. Glue overflow on the solid wood surface is difficult to clean, which will damage the texture of the solid wood surface coating and result in a low product appearance yield.

[0005] 2. The non-magnetic polarity anti-foolproof positioning structure makes it easy for the magnets to be installed incorrectly by manual or mechanical feeding. In addition, the tooling lacks a buffer structure, and the impact force of pressing can easily cause the solid wood groove to chip and the workpiece to be bumped and damaged. At the same time, the limit positioning accuracy is limited, and the magnets are easy to be skewed and offset after installation, resulting in poor consistency of magnetic attraction dimensions in batch products.

[0006] 3. With only a single layer of adhesive, the adhesive cannot completely cover the bottom and sides of the magnet. The bonding interface is not sufficiently wetted, which can easily lead to hollow spots in the bonding. After long-term use, the magnet will loosen and fall off. The bonding strength cannot meet the durability requirements of the game machine's frequent opening and closing.

[0007] 4. The process of pressing and then simply letting the product stand still to cure is long, requiring a lot of space to store the semi-finished products. It also cannot achieve simultaneous dispensing at multiple workstations, making the process cumbersome, the cost of manual error correction high, and the overall production efficiency low.

[0008] 5. Failure to implement pre-control measures to address the susceptibility of solid wood to moisture and deformation resulted in workpieces with excessive moisture content or cracks and knots entering the assembly process. Later deformation of the wood would tear the colloid, further exacerbating the problem of magnets falling off. Summary of the Invention

[0009] In view of this, the purpose of the present invention is to provide an integrated assembly process for the solid wood cover plate magnet of a game machine with layered adhesive application, which aims to solve the problem that the existing single-layer single-application assembly process cannot simultaneously take into account the appearance quality of solid wood, the bonding strength of magnets, the assembly dimensional accuracy and the efficiency of mass production.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A layered adhesive bonding assembly process for a solid wood cover plate magnet of a game console includes the following steps:

[0012] S1. Pre-treatment and screening of solid wood substrates;

[0013] Select solid wood substrates with a moisture content of 8%–12%, and remove defective products with cracks, knots, or excessive deformation. Process the selected solid wood substrates into game machine cover plates, with magnet mounting grooves. The inner wall and bottom surface of the magnet mounting grooves are treated with cross-grain sanding, and then wood chips, dust, and grease impurities are removed. Leave a 0.1–0.2 mm filling gap on one side of the magnet mounting groove.

[0014] S2. Cover plate fixing and layered composite adhesive application;

[0015] The tooling for fixing the solid wood cover of the game machine is made of integrated constant pressure locking components. The adhesive is applied in layers using a composite adhesive path of continuous ring dispensing at the bottom of the groove and micro-applying adhesive on the groove wall. The thickness of the adhesive layer at the bottom of the groove is controlled to be 0.05-0.1mm, so that the adhesive fully covers the bottom and sides of the magnet. The adhesive is applied to the bottom of the groove first, and then the magnet is placed into the mounting groove. The gap between the magnet and the mounting groove is filled by applying adhesive to the sides.

[0016] S3. Buffer compression;

[0017] The tooling also integrates a silicone elastic buffer head. After dispensing, the silicone elastic buffer head is used to press the magnet at a constant speed of 0.3-0.5MPa for 15-20 seconds.

[0018] S4. Segmented static curing;

[0019] After pressing, the workpiece is sent to a stationary position for segmented curing.

[0020] S5. Visual inspection;

[0021] After curing, a full inspection is conducted on the solid wood cover plate for defects such as glue overflow, insufficient glue, magnet misalignment, and workpiece pressure damage, and the finished product assembly is completed.

[0022] Furthermore, in step S1, after the cross-texture sanding and impurity cleaning are completed, a pre-treatment process for sealing holes is added: a thin layer of water-based sealing primer is sprayed onto the magnet mounting groove, and after low-temperature air drying and light polishing to remove dust, the capillary pores of the solid wood are sealed, preventing the exudation of wood oils, thereby improving the adhesion between the colloid and the solid wood substrate.

[0023] Furthermore, the specific steps of the sealing pretreatment process are as follows:

[0024] I. Carved solid wood cover for the game console → oil soaking → air drying → sanding;

[0025] II. Cleaning → First coat of primer → Air drying → Sanding;

[0026] III. Cleaning → Second coat of primer → Air drying → Sanding;

[0027] IV. Cleaning → Applying topcoat → Air drying → Cleaning and full inspection.

[0028] Furthermore, in step S2, the layered composite dispensing adopts a multi-point synchronous dispensing operation mode to realize the synchronous dispensing and assembly of multiple sets of magnets.

[0029] Furthermore, the tooling also integrates a magnetic polarity separation limiting groove, which can prevent the magnet from being installed in the wrong orientation and ensure that the magnet is assembled in the correct position without deviation.

[0030] Beneficial effects:

[0031] 1. Significantly improved bonding strength and long-term durability;

[0032] This invention adds a sealing pretreatment step after sanding the solid wood substrate to seal the capillary pores of the wood, preventing the leaching of internal oils and water, and avoiding contamination and delamination at the bonding interface. Combined with a layered composite adhesive application path of ring-shaped dotting at the bottom of the groove and micro-applying adhesive to the groove walls, the adhesive can completely coat the bottom and sides of the magnet, thoroughly eliminating bonding defects such as hollow spots. The tensile strength of the magnet bonding consistently reaches over 8 kg. Solid wood covers assembled using this process can pass a 5000-cycle opening and closing vibration durability test, and exhibit no magnet loosening or detachment issues under long-term, frequent use, perfectly meeting the long-term needs of game consoles.

[0033] 2. Product appearance quality and yield rate have been significantly upgraded;

[0034] On the one hand, the pre-sealing treatment can prevent glue from seeping into the solid wood conduit and causing discoloration or blemishes on the board surface; on the other hand, the layered glue application precisely controls the glue layer thickness to 0.05-0.1mm, and with the structural design that leaves a 0.1-0.2mm filling gap on each side, the standardized control of glue quantity eliminates defects such as insufficient glue or glue overflow that contaminate the solid wood coating board surface from the root, eliminating the need for additional manual cleaning of glue overflow that could damage the texture of the solid wood grain; the finished product appearance yield rate is steadily increased to over 99%, significantly reducing the cost of scrapping due to poor appearance.

[0035] 3. Precise assembly and positioning to prevent misassembly and misalignment defects;

[0036] This invention integrates a magnetic polarity separation limiting groove and a precise limiting structure into the tooling, which can automatically identify the positive and negative magnetic poles of the magnet, eliminating the problem of magnets being installed backwards from the front end of the process; the standardized limiting and positioning ensures that all magnets are installed in the correct position without deviation, and the magnetic attraction fit dimensions are highly uniform in mass production, completely solving the pain point of poor dimensional consistency in manual or simple tooling assembly.

[0037] 4. Adapts to the characteristics of solid wood substrates to avoid workpiece damage and scrapping;

[0038] The tooling is equipped with a silicone elastic buffer pressure head, which adopts a uniform speed buffer pressing process of 0.3-0.5MPa and a 15-20s pressure stabilization and holding process to buffer and offset the impact force of pressing. Combined with the pre-screening step of solid wood substrate, cracked, deformed and knotted defective workpieces are removed in advance. This not only avoids the chipping of solid wood magnet grooves and damage to the board surface during the pressing process, but also avoids the hidden danger of magnet falling off due to the tearing of the glue by the wood deformation in the later stage, which greatly reduces the scrap loss of solid wood workpieces.

[0039] 5. Shorten the production cycle and reduce site occupancy costs;

[0040] This invention uses a segmented curing process to replace the traditional single, long-term static curing process, significantly shortening the waiting time for adhesive and reducing the storage space required for semi-finished products. At the same time, the layered composite dispensing supports multi-point synchronous dispensing operations, and multiple sets of magnets can simultaneously complete the application of adhesive and pressing assembly, simplifying transfer processes, reducing manual error correction operations, and enabling fully automated parameter programming control. The overall production efficiency is more than 3 times higher than the traditional single-dispensing assembly process, making it suitable for mass industrial production and effectively reducing labor and space production costs.

[0041] 6. Highly versatile and with a wide range of applications;

[0042] The entire process is compatible with various solid wood cover plates of different materials and magnet structures of various sizes. It can be used not only for the assembly of solid wood cover plates for home console game consoles, but also for the magnet bonding processing of solid wood accessories for various game products such as handheld consoles and portable game peripherals. The process has strong versatility and good industrialization and promotion value.

[0043] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0044] Figure 1 This is a flowchart illustrating the integrated assembly process of a solid wood cover plate magnet for a game console according to the present invention. Detailed Implementation

[0045] To make the technical solutions, advantages, and objectives of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the protection scope of this application.

[0046] Example 1

[0047] like Figure 1 As shown, a layered adhesive bonding integrated assembly process for a solid wood cover plate magnet for a game console is described. The overall process includes five core steps: solid wood substrate pretreatment and screening, cover plate fixing and layered composite adhesive bonding, buffer pressing, segmented static curing, and appearance re-inspection. The detailed operation steps are as follows:

[0048] S1. Pre-treatment and screening of solid wood substrates;

[0049] Select ash wood substrate with a moisture content controlled at 10%. Manually sort and remove defective workpieces with cracks, knots, or deformation exceeding 0.2mm. Mill the qualified substrate to form the shape of the game machine cover plate, and machine magnet mounting grooves in the corresponding magnetic areas of the cover plate. Use cross-textured sandpaper to sand the inner wall and bottom of the magnet mounting groove. After sanding, use a high-pressure dust-free air gun to blow away wood chips and dust from the groove, and then wipe with a lint-free cloth dampened with neutral degreaser to remove grease and impurities from the groove. Leave a 0.15mm filling gap on one side of the magnet mounting groove. After cleaning, perform a sealing pretreatment by spraying a thin layer of solid wood water-based sealing primer onto the magnet mounting groove, with a dry film thickness of 10μm. Place it in a 45℃ constant temperature air drying station and let it stand for 10 minutes until surface dry. Then, use 1000-grit ultra-fine sandpaper to lightly polish the raised particles in the groove, blow away dust again, and seal the capillary pores inside the solid wood.

[0050] Before the sealing pretreatment, the complete pretreatment process of the solid wood cover plate is as follows: carved solid wood cover plate → oil soaking → room temperature air drying → sanding → dust-free cleaning → first primer spraying → air drying → fine sanding → cleaning → second primer spraying → air drying → sanding → cleaning → topcoat spraying → natural air drying → comprehensive cleaning and inspection.

[0051] S2. Cover plate fixing and layered composite adhesive application;

[0052] The finished painted and pre-sealed solid wood cover is placed inside the fixture with integrated constant pressure locking components for positioning and locking. The fixture is equipped with a multi-channel synchronous dispensing valve and adopts a multi-point synchronous dispensing operation mode to simultaneously apply layered composite adhesive to all magnet mounting slots. The dispensing path is continuous circular dispensing at the bottom of the slot + micro-filling adhesive on the slot wall. Layered dispensing control ensures that the adhesive layer thickness at the bottom of the slot is stably controlled at 0.08mm. After the dispensing at the bottom of the slot is completed, the magnet is placed into the corresponding mounting slot. Micro-filling adhesive on the slot wall fills the gap between the side of the magnet and the slot body, so that the adhesive fully covers the bottom and sides of the magnet.

[0053] S3. Buffer compression;

[0054] This fixture integrates a magnetic polarity separation limiting groove and a silicone elastic buffer pressure head. When placing the magnet, the magnetic polarity separation limiting groove automatically distinguishes the positive and negative poles of the magnet, preventing the magnet from being installed incorrectly from the source. After all the glue points and materials are dispensed, the silicone elastic buffer pressure head is driven downward to press the magnet with a uniform pressure of 0.4MPa for 18 seconds. The silicone buffer structure offsets the impact of the pressing, preventing the solid wood groove from chipping and the board surface from being damaged by bumps.

[0055] S4. Segmented static curing;

[0056] After the pressing and holding pressure is completed, the tooling locking components are loosened, the solid wood cover plate semi-finished product is taken out and sent to the segmented curing station. It is first pre-cured at low temperature for 6 minutes, and then left to stand at room temperature for complete curing. The segmented curing mode greatly shortens the waiting time for a single batch and reduces the space occupied by the semi-finished product stacking.

[0057] S5. Visual inspection;

[0058] After curing, manual inspection is carried out with the help of visual inspection equipment to check for defects such as glue overflow, glue shortage, magnet misalignment, and pressure damage on the surface of the solid wood cover. Defective products are rejected, and qualified products are assembled and put into storage.

[0059] The tensile strength of the solid wood cover with magnet bonding processed by the process in this embodiment can reach 8.6kg, the finished product appearance yield rate is 99.3%, and the assembled components can stably pass 5000 cycles of opening and closing vibration durability test; the whole process realizes full-process parameter program control, and the automated batch production efficiency is 3.2 times higher than the traditional single-layer single-point gluing process, which is suitable for the magnet bonding processing of various solid wood cover plates for home game consoles, handheld consoles, and portable game peripherals.

[0060] Example 2

[0061] This embodiment shares the same overall process steps as Embodiment 1, with the difference being adjustments to process parameters: walnut wood is used as the solid wood substrate, with a moisture content controlled at 8%; a 0.1mm pre-filled gap is reserved on one side of the magnet mounting groove; the dry film thickness of the sealing primer is 8μm, with an air-drying temperature of 40℃ and an air-drying time of 8 minutes; the thickness of the adhesive layer at the bottom of the groove is controlled at 0.05mm for layered dispensing; the buffer pressing pressure is 0.3MPa, and the holding time is 15s. The remaining pre-treatment, dispensing path, tooling structure, curing, and testing procedures are the same as in Embodiment 1. Testing showed that the tensile strength of the magnets in this embodiment is ≥8kg, with a yield rate of 99.1%, meeting the requirements for mass production.

[0062] Example 3

[0063] This embodiment shares the same overall process steps as Embodiment 1, with the difference being the adjustment of process parameters: rubberwood is used as the solid wood substrate, with a moisture content controlled at 12%; a 0.2mm pre-filled gap is reserved on one side of the magnet mounting groove; the dry film thickness of the sealing primer is 15μm, the air-drying temperature is 50℃, and the air-drying time is 12min; the thickness of the adhesive layer at the bottom of the groove is controlled at 0.1mm for layered dispensing; the buffer pressing pressure is 0.5MPa, and the pressure holding time is 20s. The remaining process flow remains unchanged. After processing, the product is firmly bonded, with no excess or missing glue, and no pressure damage to the solid wood. The durability and production efficiency indicators are the same as in Embodiment 1.

[0064] Compared with the existing traditional single-layer single-application assembly process, the above three sets of embodiments can accurately control the adhesive layer thickness and eliminate defects such as overflow and insufficient adhesive. The polar magnetic separation limiting groove and silicone buffer pressure head respectively solve the problems of magnet misalignment and solid wood pressure damage. The sealing pretreatment combined with layered composite dispensing greatly improves the bonding strength, and the segmented curing and multi-point synchronous dispensing significantly improve production efficiency, which has outstanding industrial application value.

[0065] It is hereby declared that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
