Description
Technical Field
[0001] This invention relates to the field of furniture processing technology, specifically to a method for splicing irregularly shaped wood and spliced boards. Background Technology
[0002] Wood is a collective term for plant tissues that develop inward from the vascular cambium, including the xylem and parenchyma rays. Wood plays a significant supporting role in human life and is widely used in production and daily life. Depending on the application, wood is typically processed into various shapes. Specifically, before use, raw wood is generally pre-processed into shapes such as planks, strips, squares, cylinders, and prisms according to the intended use. When producing specific furniture products, the appropriate shape of wood is selected based on the product's requirements. During processing, irregularly shaped scraps are often generated. These scraps are difficult to utilize, and discarding them directly would be wasteful. The traditional method is to crush the scraps, then use adhesives to press them together, and finally attach melamine-impregnated paper to the surface to create engineered wood panels. This method avoids wood waste. However, this method cannot showcase the true texture of the wood. With economic development and improved living standards, consumers are placing higher demands on the appearance of engineered wood panels. Therefore, a method is needed that can utilize irregularly shaped wood while showcasing its natural grain. Summary of the Invention
[0003] To address the aforementioned problems, this invention provides a method for splicing irregularly shaped timber, and a spliced board using the aforementioned method for splicing irregularly shaped timber.
[0004] This invention is implemented using the following scheme: A method for splicing irregularly shaped timber includes the following steps: S1 provides several irregularly shaped timbers; S2, acquire the image of the irregularly shaped wood and calculate the projected area of the irregularly shaped wood to generate the first outline map of the irregularly shaped wood; S3, Determine the dimensions of the boards to be spliced; S4. Use a computer to retrieve the first outline of the irregularly shaped timber, select the irregularly shaped timber according to the board size, and simulate the arrangement of the selected irregularly shaped timber to generate a simulated arrangement diagram. S5. According to the simulated layout diagram, take the corresponding irregular wood and arrange the selected irregular wood in a mold. After the arrangement is completed, inject adhesive and press the arranged irregular wood from the horizontal and vertical directions. S6. After the adhesive has cured, perform post-processing on the assembled panels.
[0005] Furthermore, in step S4, when simulating the arrangement of irregularly shaped timbers, the following steps are included: S41. Set up a layout area according to the board size. Starting from the edge of the board, select irregularly shaped woods from the outside to the inside and arrange them in sequence. The area covered by the irregularly shaped woods is larger than the layout area. For adjacent irregularly shaped woods, prioritize those with similar outer contours. For irregularly shaped woods with significantly different contours, overlap the edges of the two irregularly shaped woods. S42, Based on the board size, generate a first cutting line on the first outline of the irregularly shaped wood located at the edge, and generate a second cutting line in the overlapping area of the corresponding first outline of the irregularly shaped wood. S43, remove overlapping parts and parts exceeding the board size, and number the first outline of each irregularly shaped piece of wood to generate the final simulated layout diagram.
[0006] Furthermore, in step S43, after generating the simulated layout diagram, the corresponding irregularly shaped timber is cut using a cutting device according to the first cutting line and the second cutting line, and then the irregularly shaped timber is stored in an orderly manner according to its number.
[0007] Furthermore, in step S4, when simulating the arrangement of irregularly shaped timbers, the following steps are included: S41, set a layout area according to the board size, retrieve the first outline of the irregular wood, and select the irregular wood from the outside to the inside starting from the edge of the board. The area covered by the irregular wood is larger than the layout area. For adjacent irregular wood layouts, prioritize irregular wood with similar outer outlines. S42, After the irregularly shaped timbers are arranged to fill the arrangement area, draw the outline of each interval between adjacent irregularly shaped timbers in the arrangement area to obtain several second outline drawings corresponding to each interval and number them. S43, Based on the board size, generate a first cutting line on the first outline of the irregularly shaped wood located at the edge; S44, remove overlapping parts and parts exceeding the board size, and number the first outline of each irregularly shaped piece of wood to generate the final simulated layout diagram.
[0008] Furthermore, after obtaining the second outline in steps S43 and S42, wood is taken and processed on a processing device according to the second outline to produce several fillers corresponding to several second outlines. In step S5, after the irregular wood is arranged, the fillers are placed into the corresponding intervals one by one according to the number of the simulated arrangement diagram. After the fillers are placed, adhesive is injected.
[0009] Furthermore, step S5 includes the following steps: S51 provides a mold and calls up the simulated layout diagram; S52, a reinforcing layer is laid at the bottom of the mold, and an adhesive is applied to the reinforcing layer; S53. According to the simulated layout diagram, take the corresponding irregularly shaped wood and place the irregularly shaped wood one by one on the reinforcing layer to form the prototype of the board. S54 After the irregularly shaped timbers are placed, inject adhesive into the board prototype so that the adhesive fills the gaps between adjacent irregularly shaped timbers; S55 presses together the arranged irregularly shaped timbers in both horizontal and vertical directions to press the board prototype to the set board size.

[0018] The image includes: First outline Figure 1 1. First cutting line 2. Second cutting line 3. Second contour diagram 4. Detailed Implementation
[0019] To facilitate understanding of the present invention by those skilled in the art, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. Example
[0020] Reference Figures 1 to 2 The present invention provides a method for splicing irregularly shaped timber, comprising the following steps: S1 provides a number of irregularly shaped timbers, including timber processing scraps, offcuts and natural irregularly shaped timbers; S2 uses high-precision vision equipment (such as industrial cameras and 3D scanners) to acquire pre-processed images of irregularly shaped wood. Image processing algorithms (such as edge detection and contour extraction algorithms) are then used to analyze the images, calculate the projected area of the irregularly shaped wood, and simultaneously generate a first contour that accurately reflects the shape characteristics of the wood. Figure 1 The accuracy error of the contour drawing is controlled within ±0.1mm; S3, Determine the size of the boards to be spliced (it can be a general specification or a special specification). S4, Use computer-aided design software to retrieve the first outline of the irregularly shaped timber. Figure 1 Select irregularly shaped timbers according to the board size, and simulate the arrangement of the selected irregularly shaped timbers to generate a simulated arrangement diagram; S5. According to the simulated layout diagram, take the corresponding irregular wood and arrange the selected irregular wood in a mold. After the arrangement is completed, inject adhesive and press the arranged irregular wood from the horizontal and vertical directions. S6. After the adhesive has cured, perform post-processing on the assembled panels.
[0021] For ease of understanding and clarity of lines, the accompanying drawings of this embodiment only use the outline of a simple-shaped piece of irregularly shaped wood. In actual implementation, the shape of the irregularly shaped wood is not limited to the shape shown in the drawings. The dotted lines in the drawings represent the outline of the board (i.e., the arrangement area), which is also the first cutting line 2, while the dashed lines represent the second cutting line 3.
[0022] In step S4, the simulated arrangement of irregularly shaped timber includes the following steps: S41, in the computer-aided design software, a layout area is set according to the board size. Starting from the edge of the board, irregularly shaped timbers are selected and arranged sequentially from the outside to the inside (i.e., arranged sequentially from the edge to the center). The area covered by the irregularly shaped timbers is larger than the layout area. In this embodiment, the total area covered by the irregularly shaped timbers is controlled to be 10-20% larger than the layout area (15% in this embodiment), leaving room for cutting. Adjacent irregularly shaped timbers are preferentially selected based on their similar outer contours and matching curvatures. For irregularly shaped timbers with significantly different contours, the edges of the two irregularly shaped timbers are overlapped to compensate for the contour differences and reduce or eliminate gaps. Figure 1 As shown, during the arrangement process, the first rotating contour can be started first. Figure 1 Lay them out at regular intervals, then slowly move them closer to the center of the area. S42, based on the board size, the first outline of the irregularly shaped wood located at the edge. Figure 1 A first cutting line 2 is generated, which coincides with the edge contour of the board. It is used to remove the part that exceeds the size of the board and is applied to the first contour of the corresponding irregularly shaped wood. Figure 1 A second cutting line 3 is generated in the overlapping area. The second cutting line 3 can be set along the symmetrical center line or the optimal fitting line of the overlapping area to ensure that the adjacent wood can fit tightly after cutting. Depending on the specific situation, a cutting line can also be generated only in one of the two adjacent irregular woods (i.e., only the overlapping part of one of the irregular woods is removed). S43, remove the portions exceeding the board size and overlapping parts from the irregularly shaped timber outline drawing, and perform a first outline analysis on each irregularly shaped timber. Figure 1 Number the pieces (linking the numbers to information such as the placement of irregularly shaped timbers and cutting lines) to generate the final simulated layout diagram.
[0023] In step S43, after generating the simulated layout diagram, the corresponding irregularly shaped wood is cut using a cutting device according to the first cutting line 2 and the second cutting line 3, and then the irregularly shaped wood is stored in an orderly manner according to its number.
[0024] Step S5 includes the following steps: S51 provides a mold and calls up a simulated layout diagram. The inner wall of the mold is coated with an anti-slip and anti-stick coating to facilitate subsequent demolding of the board. The mold has two fixed side walls and two movable side walls. The four inner walls surround a layout space (the space is rectangular) corresponding to the size of the board. In the initial state, the two movable side walls are slightly away from the layout space, so they do not need to be tightly fitted when initially arranging irregularly shaped wood. S52, a reinforcing layer is laid at the bottom of the mold, and an adhesive is applied to the reinforcing layer. The reinforcing layer can be made of materials such as fiberglass cloth or non-woven fabric, which can improve the overall strength and deformation resistance of the spliced panels. S53. According to the simulated layout diagram and timber number, take the corresponding irregular timber one by one and place the irregular timber on the reinforcing layer to form the board prototype. S54. After the irregularly shaped timbers are placed, an adhesive injection device is used to inject adhesive into the board prototype, so that the adhesive fills the gap between adjacent irregularly shaped timbers. After the adhesive injection is completed, let it stand for a certain period of time to allow the adhesive to penetrate evenly. S55 presses the arranged irregularly shaped wood pieces together in both horizontal and vertical directions, pressing the board shape to the set board size, expelling air from the gaps, and ensuring that the adhesive is in full contact with the wood and bonded firmly.
[0025] In step S4, when simulating the arrangement of the selected irregularly shaped wood, the placement direction of the irregularly shaped wood is set according to the texture of the irregularly shaped wood. The texture directions of adjacent irregularly shaped wood are the same or different. For example, the textures of adjacent irregularly shaped wood can be interspersed to create a visual experience of changing gloss.
[0026] In addition, in practical implementation, mortise and tenon structures can be machined on the side walls of adjacent irregularly shaped timbers to reduce the use of adhesives.
[0027] In step S1, after providing several irregularly shaped pieces of wood, the wood undergoes pretreatment, which includes: S11. Screening of irregularly shaped timber to remove those that do not meet the requirements for splicing and processing. Specifically, the irregularly shaped timber is initially screened based on appearance, material and size to remove those that are infested with insects, rotten, have cracks exceeding the allowable range, or have uneven material, thus ensuring the basic quality of the timber. S12 uses grinding, cutting and other methods to remove defects such as knots, burrs and local damage on the surface of irregularly shaped wood, and cuts the irregularly shaped wood to a preset thickness (the thickness is adapted to the thickness of the boards to be spliced). S13, the irregularly shaped wood is soaked in water at a temperature of 70-90℃ (e.g., 80℃; the specific temperature can be adjusted according to the type of wood; the temperature range in this embodiment is just an example). The soaking time is 2-3 hours (e.g., 2.5 hours) to remove resin and impurities from the wood, soften the wood fibers, and improve the flexibility of the wood and the adhesion of subsequent adhesives. After soaking, the wood is dried in a gradient drying process. First, it is dried at 60-70℃ to a moisture content of 15-25%, and then dried at 45-55℃ to a moisture content of 8-13% to avoid cracking and deformation of the wood due to rapid drying. S14 involves a secondary screening of irregularly shaped timber to remove timber that has cracked, warped, or has an unacceptable moisture content during the soaking and drying process. S15, moisture conditioning treatment for irregularly shaped wood; S16 is used to treat irregularly shaped wood for insect prevention. The environmentally friendly insect repellent is evenly sprayed or coated onto the irregularly shaped wood by spraying, brushing or vacuum impregnation. After treatment, the wood is allowed to air dry naturally to prevent subsequent insect infestation.
[0028] In step S12, the irregular wood is cut to a preset thickness using a cutting device. After cutting, the outer wall of the irregular wood is cut along the outer contour of the irregular wood so that the outer wall of the irregular wood is perpendicular to the upper and lower bottom surfaces, ensuring that the wood thickness is uniform and the end face is flat, which facilitates subsequent splicing and pressing.
[0029] In step S6, after the adhesive has fully cured, the assembled boards are removed from the mold for post-processing. First, demolding and cleaning are performed, scraping off excess adhesive from the surface and edges to avoid damaging the wood. Then, graded sanding is carried out. After sanding, compressed air is used to blow away dust from the board surface, followed by wiping with anhydrous ethanol to remove residual impurities and grease, improving the adhesion of subsequent coatings. Next, coating is applied. Depending on the application, water-based varnish, wood wax oil, or polyurethane paint can be selected. A dust-free spray gun is used, applying 2-3 thin coats, each 8-12 μm thick, with a 6-8 hour interval between coats to ensure a uniform, drip-free, and bubble-free coating. If wood wax oil is used, it can be applied evenly with a cotton cloth. After application, let it stand for 2-3 hours, then lightly sand with fine sandpaper to remove surface roughness before applying a second coat. After coating, the boards are placed in a constant temperature and humidity environment for natural curing for 24-48 hours to allow the coating to completely dry and set. Finally, a comprehensive inspection of the finished products is carried out. The inspection items include dimensions (whether the dimensions are within the acceptable error range) and surface coating quality inspection (uneven coating, cracks, splicing gaps, etc.). Products that pass the inspection are stored in the warehouse in categories and separated by padding to avoid compression and deformation. Products that fail the inspection are reworked according to the type of defect. Example
[0030] like Figure 3 As shown, in this embodiment, step S4, when simulating the arrangement of irregularly shaped timbers, includes the following steps: S41, In the computer-aided design software, a layout area is set according to the size of the board. Starting from the edge of the board, irregularly shaped wood is selected and arranged from the outside to the inside (i.e., irregularly shaped wood is arranged in sequence from the edge to the center). The area covered by the irregularly shaped wood is larger than the layout area. In this embodiment, the total area covered by the irregularly shaped wood is controlled to be 10-20% larger than the area of the layout area (15% in this embodiment). Allowance is reserved for cutting. Adjacent irregularly shaped woods are preferentially selected with similar outer contours and matching curvatures. S42, after the irregularly shaped timbers fill the entire arrangement area, draw the outline of each gap between adjacent irregularly shaped timbers within the arrangement area, obtaining several second outline diagrams 4 corresponding to each gap, and number them to ensure the correspondence between subsequent filler parts and gaps, avoiding confusion. Figure 3 The shaded area in the figure is the second outline diagram 4; S43, based on the board size, the first outline of the irregularly shaped wood located at the edge. Figure 1 A first cutting line 2 is generated, which coincides with the edge contour of the board material and is used to remove the part that exceeds the size of the board material. S44, remove overlapping portions and portions exceeding the board dimensions, and perform a first contouring of each irregularly shaped piece of wood. Figure 1 Number them to generate the final simulated layout diagram.
[0031] After obtaining the second outline diagram 4 in steps S43 and S42, wood is taken and several filler parts corresponding to several second outline diagrams 4 are processed on the processing equipment according to the second outline diagram 4. After processing, the filler parts are marked according to the corresponding second outline diagram 4 number and stored in an orderly manner.
[0032] In step S5, after the irregularly shaped wood is arranged, the fillers are placed into the corresponding gaps one by one according to the numbers on the simulated layout diagram. After the fillers are placed, adhesive is injected. Apart from this, all other steps in this embodiment are the same as in embodiment 1. Example
