Description

Technical Field

[0001] This invention relates to the field of panel processing technology, specifically a method and apparatus for processing furniture panels. Background Technology

[0002] In the furniture manufacturing industry, the precise and efficient cutting of boards (such as wood-based panels, engineered wood panels, and composite panels) is one of the core processing links. With the popularization of laser processing technology, laser cutting machines have been widely used in the cutting and hollowing processes of furniture boards due to their significant advantages such as high cutting precision, smooth cuts, no need for molds, and flexible processing of complex irregular contours.

[0003] Laser cutting requires sufficient unobstructed space below the material being cut (i.e., along the path of the laser beam after penetrating the material) to allow for the smooth discharge of auxiliary gas and cutting debris and fumes, and to prevent the laser beam from damaging the cutting table supporting the material. To meet the requirements of suspended cutting, existing technologies generally use dedicated cutting tables with discontinuous support structures, such as blade-type tables, honeycomb-type tables, or bed-of-needles tables. These tables support the material through a series of discrete support points or support bars, creating the necessary process gap between the bottom surface of the material and the table base. Although this design can meet the basic space requirements of laser cutting in most cases, the support structure (such as the walls of a honeycomb cell, the tips of a bed of needles, or the top of a blade) must be in direct contact with the bottom surface of the material to provide stable support. When the preset cutting trajectory happens to pass through these contact points, the high-energy laser beam will continue to act on the support structure below after completely cutting through the material, inevitably causing localized ablation damage to the support structure, thus seriously affecting the service life of the support structure.

[0004] Therefore, the present invention proposes a method and apparatus for processing furniture boards to solve the above problems. Summary of the Invention

[0005] The purpose of the embodiments of the present invention is to provide a method and apparatus for processing furniture boards in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A furniture board processing device includes a cutting table, a placement area on the cutting table for placing boards, and a cutting component for cutting the boards. The placement area is arranged with support blocks for supporting the boards. Each support block can be raised and lowered independently. The support block perpendicular to the cutting path is in a lower predetermined position and maintains a predetermined distance from the lower side of the board. The other support blocks are in an upper predetermined position and maintain contact with the lower side of the board.

[0007] In one alternative embodiment: the processing device further includes a plate fixing assembly for fixing the plate, the plate fixing assembly including a frame arranged to surround the placement area, an abutment member disposed inside the frame for abutting against the plate, and a plurality of first telescopic members for driving the abutment member to perform an abutment / relaxation action.

[0008] In one alternative: the cutting table is provided with a cavity perpendicular to the placement area, the cavity is provided with a mesh-like load-bearing plate, the support block array is arranged above the load-bearing plate, and the load-bearing plate is provided with a second telescopic member that is paired with the support block to drive the support block to rise and fall.

[0009] In one alternative: the cavity is equipped with a pull-out collection drawer for collecting cutting debris located below the load-bearing plate.

[0010] In one alternative: the cavity sidewall is provided with a number of exhaust ports for discharging cutting fumes.

[0011] In one alternative: the support blocks are arranged in a gap array, the processing device further includes mounting parts corresponding to the support blocks one by one, the support blocks are hinged to the corresponding mounting parts, and a torsion spring is provided at the hinge point between the support block and the mounting part, the movable end of the second telescopic member is fixedly connected to the corresponding mounting part, and the load-bearing plate is also provided with a top rod corresponding to the support blocks one by one. When the support block is in the lower set position, it is in an inclined state under the pushing action of the corresponding top rod.

[0012] In one alternative: the upper end of the push rod is rotatably embedded with ball bearings.

[0013] A method for processing furniture boards, using any of the furniture board processing devices described in the above technical solutions, includes the following steps: S1: Place the board in the placement area and support it with the array of support blocks; S2: Fix the plate and lower the support block that is perpendicular to the cutting path to the lower set position, maintaining a set distance between it and the lower side of the plate to allow for a safe cutting space. The other support blocks do not move and remain in the upper set position, maintaining contact with the lower side of the plate. S3: The cutting component cuts the board material according to a predetermined cutting path.

[0014] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows: First, the board is placed in the placement area and supported by the array of support blocks. Then, the board is fixed and the support blocks perpendicular to the cutting path are lowered to a lower set position, maintaining a set distance from the bottom of the board to allow for safe cutting space. The remaining support blocks remain in the upper set position, in contact with the board. Then, the cutting component cuts the board according to the predetermined cutting path. The cutting process does not cause any damage to the support blocks, greatly improving the service life of the board support structure.

Detailed Implementation

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Please see Figure 1 and Figure 2 A furniture board processing device includes a cutting table 1, a placement area 6 on the cutting table 1 for placing boards, and a cutting component 2 for cutting the boards. The placement area 6 is arranged with support blocks 7 for supporting the boards. Each support block 7 can be raised and lowered independently. The support block 7 perpendicular to the cutting path is in a lower set position and maintains a set distance from the lower side of the board. The other support blocks 7 are in an upper set position and maintain contact with the lower side of the board.

[0026] It should be noted that the cutting component 2 includes a laser cutting head, a cutting energy and medium transmission system (such as a laser, plasma power supply, etc.), a motion and positioning system (driving the laser cutting head to move and position), a control system, and an auxiliary and safety system, etc., which are existing technologies and will not be elaborated here. In addition, the process of obtaining the cutting path of the laser cutting head through the background control system of the processing device and controlling the corresponding support block 7 to move down according to the obtained path data is also an existing mature technology (the operator or automatic system (such as a CCD vision alignment system) identifies the physical reference edge of the plate and sets the coordinate value corresponding to the reference edge as the origin of the workpiece coordinate system of the CNC system of the device through the edge finding operation), and there are no technical obstacles, so it will not be elaborated here.

[0027] First, the board is placed in the placement area 6 (achieved by means of a loading trolley, etc.). The board is supported by the array of support blocks 7. Then, the board is fixed and the support blocks 7, which are perpendicular to the cutting path, are lowered to a lower set position, maintaining a set distance from the bottom of the board to allow for a safe cutting space. The other support blocks 7 remain in the upper set position, in contact with the board. Then, the cutting component 2 cuts the board according to the predetermined cutting path. The cutting process does not cause any damage to the support blocks 7, greatly improving the service life of the board support structure.

[0028] Please see Figures 1-3In one embodiment of the present invention, the processing device further includes a plate fixing assembly 3 for fixing the plate. The plate fixing assembly 3 includes a frame 301 surrounding the placement area 6, an abutment member 302 disposed inside the frame 301 for abutting against the plate, and a plurality of first telescopic members 303 for driving the abutment member 302 to perform abutment / release action. The first telescopic member 303 is an electric telescopic rod, telescopic cylinder, etc. in the prior art. The plate is placed in the placement area 6, that is, inside the frame 301. The abutment member 302 is driven by the plurality of first telescopic members 303 to move towards the plate until a set abutment state is reached (equipped with a corresponding sensing module for real-time monitoring of the magnitude of the abutment force (not shown in the figure), the measured value is compared with a preset threshold, and the background control system determines and outputs a tight / untight signal, which is the prior art and will not be described in detail here), thus fixing the plate.

[0029] Please see Figure 1 , Figure 4 and Figure 5 In one embodiment of the present invention, the cutting table 1 is provided with a cavity 4 perpendicular to the placement area 6. The cavity 4 is provided with a mesh-like load-bearing plate 8 (to ensure that cutting slag can pass through). The support blocks 7 are arranged in an array above the load-bearing plate 8. The load-bearing plate 8 is provided with a second telescopic member 9 that is paired with the support block 7 to drive the support block 7 to rise and fall. The second telescopic member 9 is an electric telescopic rod, telescopic cylinder, etc. in the prior art. By extending and retracting the second telescopic member 9, the corresponding support block 7 is raised and lowered to realize the switching of the upper / lower set position.

[0030] Furthermore, in this embodiment, a collection tray 5 for collecting cutting slag is provided in the cavity 4 below the load-bearing plate 8. The cutting slag falls into the collection tray 5 and is collected. When it is necessary to clean the slag collected in the collection tray 5, the collection tray 5 is pulled out of the cavity 4 and poured out.

[0031] Furthermore, in this embodiment, the sidewall of the cavity 4 is provided with a number of exhaust ports for discharging cutting fumes. The fumes generated from cutting the plate will enter the cavity 4 and be discharged through the exhaust ports.

[0032] Based on the previous embodiment, please refer to Figures 4-6 In one embodiment of the present invention, the support blocks 7 are arranged in a gap array, and the processing device further includes mounting members 10 corresponding to the support blocks 7 one by one. The support blocks 7 are hinged to the corresponding mounting members 10, and a torsion spring 11 is provided at the hinge point between the support blocks 7 and the mounting members 10. The movable end of the second telescopic member 9 is fixedly connected to the corresponding mounting member 10. The load-bearing plate 8 is also provided with a top rod 12 corresponding to the support blocks 7 one by one. When the support blocks 7 are in the lower set position, they are in an inclined state under the pushing action of the corresponding top rod 12.

[0033] In this embodiment, the purpose of the gap array arrangement of the support blocks 7 is to provide sufficient space for the support blocks 7 to deflect; the support blocks 7 are in a lower set position, and are in an inclined state under the pushing action of the corresponding push rod 12 (e.g., Figure 6 As shown in the figure, this prevents cutting debris from falling onto the support block 7 and achieves the self-cleaning effect of the support block 7. When the support block 7 is switched to the upper set position, it returns to the horizontal state under the action of the torsion spring 11.

[0034] Furthermore, in this embodiment, a ball bearing 13 is rolledly embedded at the upper end of the top rod 12. By setting the ball bearing 13, the sliding friction between the support block 7 and the top rod 12 is changed to rolling friction, thereby improving the smoothness of tilting the support block 7.

[0035] The present invention also provides a method for processing furniture boards, using any of the furniture board processing devices described in the above technical solutions, comprising the following steps: S1: Place the board in the placement area 6 and support it with the array of support blocks 7; S2: Fix the plate and lower the support block 7, which is perpendicular to the cutting path, to the lower set position, maintaining a set distance between it and the lower side of the plate to allow for a safe cutting space. The other support blocks 7 remain in the upper set position and are in contact with the lower side of the plate. S3: The cutting component 2 cuts the board according to the predetermined cutting path.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
