Description

Technical Field

[0001] The invention belongs to the technical field of laser cutting, in particular to a laser cutting device used for furniture processing. Background Art

[0002] Furniture processing refers to the process of making furniture products from raw materials through a series of processes and procedures; this includes the processing of raw materials such as wood and metal, as well as the production and assembly of furniture parts; there are many types of furniture at present, generally including: solid wood furniture, panel furniture, soft furniture, metal furniture, etc.

[0003] In recent years, laser cutting technology has been used more and more widely in furniture manufacturing. Laser cutting technology has the advantages of high precision, high efficiency, and high quality, and can be used for processing various materials, including wood, plastic, metal, etc. In furniture manufacturing, laser cutting technology can be used for cutting, engraving, punching, etc., bringing more possibilities to furniture manufacturing;

[0004] In metal furniture manufacturing, especially when engraving some patterns on metal plates, the traditional engraving method is to engrave patterns on metal plates through slotting machines or cutting machines. Since it is hand-engraved, there will be deviations between the engraved patterns and the actual patterns. Laser cutting technology can engrave patterns on metal plates, wood, plastic and other materials by controlling the laser beam. This technology can produce many exquisite patterns, such as European patterns, animal images, company logos, etc., while ensuring the beauty of the patterns.

[0005] When using a laser cutting machine to engrave a metal sheet, you first need to place the metal sheet on a workbench, and then use the CNC control system to control the cutting head to cut a pattern on the sheet.

[0006] When cutting patterns on thin plates, the plates may warp. When the cutting head cuts the warped plates, the cut patterns will be different from the original patterns, thus affecting the accuracy of the cut patterns. If some plates are bent or warped before cutting, the cut patterns will also be different from the original patterns. Summary of the invention

When the correction mechanism follows the X-axis driving box to move in the X-axis direction, the top plate and the bottom plate can be driven to move along the plate. During the movement, the bottom plate can support the plate. At the same time, the first straightening roller on the top plate can squeeze the plate passing between the top plate and the bottom plate. Therefore, the plate can be straightened first by the squeezing of the first straightening roller. The straightened plate will then pass through the cutting groove and then be cut by the cutting head in the cutting groove, thereby avoiding the position cut by the cutting head from being in a warped state, thereby affecting the accuracy of the cutting pattern.

[0035] 2. In the laser cutting equipment for furniture processing described in the present invention, when the cutting head cuts along the Y-axis direction, the second straightening roller moving with the laser cutter will first squeeze the plate in the cutting groove, so as to press the part of the plate that is warped in the Y-axis direction straight. After the plate is straightened, it is then cut by the cutting head, so as to further avoid the situation where the plate warps, which will affect the accuracy of the cut pattern. By setting the first straightening roller and the second straightening roller, the cutting head can flatten the plate regardless of whether it is cutting along the X-axis or the Y-axis, so as to further improve the cutting accuracy of the plate.

[0036] 3. The laser cutting equipment for furniture processing described in the present invention has a driven belt rotatably connected to the driven rollers rotating on both sides of the leakage groove. When the base plate moves along the plate, the driven belt will rotate due to the obstruction of the plate. In this process, the friction between the plate and the base plate can be reduced, so that the base plate can be moved better along the plate. At the same time, in the process of the driven belt rotating, impurities between the driven belt and the base plate can be taken away, so as to avoid impurities remaining on the upper surface of the base plate, which will prop up the passing plate and cause the plate to appear warped.

[0054] The two mounting plates 2 are respectively mounted on the two X-axis drive boxes 13; the top plates 21 are slidably connected to the opposite sides of the two mounting plates 2; the first cylinders 22 are fixedly connected to the tops of the two mounting plates 2, and the extension shafts of the first cylinders 22 are fixedly connected to the top plates 21;

[0055] A cutting groove 23 is provided in the middle of the top plate 21; when cutting the plate, the cutting head 16 will extend into the cutting groove 23; both sides of the cutting groove 23 are located at the bottom end surface of the top plate 21, and are rotatably installed with uniformly arranged first straightening rollers 24;

[0056] A bottom plate 3 is provided below the top plate 21 and between the two mounting plates 2, and the bottom plate 3 is fixedly connected to the two mounting plates 2; a drain groove 31 is provided in the middle of the bottom plate 3, and the drain groove 31 corresponds to the cutting head 16;

[0057] The laser cutter 15 is provided with Y-axis alignment components on both side end surfaces close to the mounting plate 2, and the Y-axis alignment components are used to calibrate the cut plate;

[0058] The two sides of the crossbeam 12 are both provided with fixing mechanisms on the bed 1, and the fixing mechanisms are used to fix the plate;

[0059] In this embodiment, both of the fixing mechanisms include a fixing plate 4;

[0060] The two fixing plates 4 are located at both sides of the cross beam 12, and the height of the fixing plates 4 is flush with the height of the bottom plate 3; the two sides of the two fixing plates 4 are fixedly connected with the second cylinder 41;

[0061] The two second cylinders 41 are both fixedly connected to the elongated shafts at the top thereof with moving blocks 42; the two opposite moving blocks 42 are rotatably connected with evenly arranged rollers 43, and the outer ring surfaces of the plurality of rollers 43 are jointly rotated with a rotating belt 44; the rollers 43 are driven by a first servo motor 45;

[0062] Below the two moving blocks 42, a slider 46 is fixedly connected to the bottom end surface of the fixed plate 4 through a connecting plate; a slide groove is provided on one side of the bed 1 close to the slider 46, and the slider 46 slides in the slide groove;

[0063] The slider 46 is threadedly engaged with a screw rod 47 through a thread groove, and the screw rod 47 is installed on the bed 1 and driven by a second servo motor 48;

[0064] Specifically, when cutting a pattern on a plate, firstly, the first cylinder 22 is controlled to extend. When the first cylinder 22 extends, the top plate 21 is driven to move upward, thereby increasing the distance between the top plate 21 and the bottom plate 3. Then, the plate is passed between the top plate 21 and the bottom plate 3, and the plate is first placed on the bottom plate 3. Then, the second servo motor 48 is controlled to rotate. The second servo motor 48 drives the screw rod 47 to rotate. Since the slider 46 is threadedly engaged with the screw rod 47 through the thread groove, the slider 46 is driven to move toward the plate position. At the same time, the slider 46 drives the fixing mechanisms on both sides to move toward the plate position. When the two fixing mechanisms move to the positions on both sides of the plate, the second cylinders 41 on the two fixing mechanisms are controlled to extend. The extended second cylinder 41 drives the moving block 42 to move upward. The moving block 42 that moves upward drives the roller 43 and the transfer belt 44 between the two moving blocks 42 to move upward, thereby increasing the distance between the transfer belt 44 and the fixed plate 4. Then, the two sides of the plate are respectively inserted between the transfer belt 44 and the fixed plate 4. Then, the second servo motor 48 is controlled to rotate. The second servo motor 48 drives the screw rod 47 to rotate. Since the slider 46 is threadedly engaged with the screw rod 47 through the thread groove, the slider 46 is driven to move toward the plate position. At the same time, the slider 46 drives the fixing mechanisms on both sides to move toward the plate position. When the two fixing mechanisms move to the positions on both sides of the plate, the second cylinders 41 on the two fixing mechanisms are controlled to extend. The extended second cylinder 41 drives the moving block 42 to move upward. The moving block 42 that moves upward drives the roller 43 and the transfer belt 44 between the two moving blocks 42 to move upward, thereby increasing the distance between the transfer belt 4 The second cylinder 41 contracts, thereby driving the roller 43 and the transfer belt 44 to move downward until the plate is clamped between the fixed plate 4 and the transfer belt 44. When both sides of the plate are clamped in the fixing mechanism, the first servo motors 45 in the two fixing mechanisms are controlled to rotate, and the first servo motor 45 in the fixing mechanism on the left side of the beam 12 drives the roller 43 and the transfer belt 44 to rotate clockwise, and the first servo motor 45 in the fixing mechanism on the right side of the beam 12 drives the roller 43 and the transfer belt 44 to rotate counterclockwise. The rotating roller 43 and the rotating belt 44 in the fixing mechanism rotate in opposite directions. During the rotation of the two rotating belts 44, the plate is driven to move to both sides at the same time, so that the plate can be pulled and straightened; then the first servo motor 45 is controlled to stop rotating, and the first cylinder 22 is controlled to contract at the same time. The first cylinder 22 drives the top plate 21 and the first straightening roller 24 to move downward, and the plate is located between the bottom plate 3 and the first straightening roller 24. At this time, the plate is clamped in the two fixing mechanisms, and then the plate can be cut into a pattern;

[0065] More specifically, when cutting a pattern on a plate, the CNC system controls the X-axis drive box 13 and the Y-axis drive box 14 to move according to the shape of the pattern to be cut, thereby driving the cutting head 16 to move according to the shape of the pattern. During the movement of the cutting head 16, the laser cutter 15 is controlled to move downward, and the downwardly moving laser cutter 15 drives the cutting head 16 to move downward into the cutting groove 23, and makes the cutting head 16 contact with the plate in the cutting groove 23 and cut. Since the mounting plate 2 is fixed on the X-axis drive box 13, when the X-axis drive box 13 moves, it drives the top plate 21 and the bottom plate 3 to move along the plate, and at the same time, the cutting groove 23 always moves with the cutting head 16, so the cutting head 16 is During mobile cutting, the top plate 21 and the bottom plate 3 following the cutting head 16 will move along the plate; when the top plate 21 and the bottom plate 3 move along the plate, the surface of the bottom plate 3 will contact the plate and move along the plate, thereby supporting the plate, and at the same time, the first straightening roller 24 on the top plate 21 can squeeze the plate passing between the top plate 21 and the bottom plate 3. Since the bottom of the plate is supported by the bottom plate 3, the plate can be straightened first by squeezing by the first straightening roller 24, and the straightened plate will then pass through the cutting groove 23, and then be cut by the cutting head 16 in the cutting groove 23, thereby preventing the position cut by the cutting head 16 from being in a warped state, thereby affecting the accuracy of the cutting pattern;

[0066] Furthermore, when the Y-axis driving box 14 moves, it will drive the cutting head 16 to move in the cutting groove 23, so that the plate in the cutting groove 23 can be cut. Since the first straightening rollers 24 on both sides press the plate, it can prevent the plate from warping when the cutting head 16 cuts along the Y-axis, thereby affecting the accuracy of the cutting pattern. Since the bottom plate 3 is provided with a leakage groove 31, and the leakage groove 31 corresponds to the cutting head 16, the laser beam emitted by the cutting head 16 will be staggered with the bottom plate 3, thereby preventing the laser beam from acting on the bottom plate 3 and causing damage to the bottom plate 3. When the plate cutting is completed, the cutting head 16 is controlled to restore the initial state, and the X-axis driving box 13 and the Y-axis driving box 14 are controlled to stop moving, and then the first cylinder 22 and the second cylinder 41 are controlled to extend, so that the top plate 21 and the bottom plate 3 are separated, and the fixed plate 4 is separated from the rotating belt 44, and then the plate can be taken out.

[0067] Furthermore, by controlling the top plate 21 and the bottom plate 3 to approach each other, and using the first straightening roller 24 on the top plate 21 to squeeze the plate onto the bottom plate 3, when the correction mechanism follows the X-axis drive box 13 to move in the X-axis direction, the top plate 21 and the bottom plate 3 can be driven to move along the plate. During the movement, the bottom plate 3 can support the plate, and at the same time, the first straightening roller 24 on the top plate 21 can squeeze the plate passing between the top plate 21 and the bottom plate 3. Therefore, through the squeezing of the first straightening roller 24, the plate can be straightened first, and the straightened plate will then pass through the cutting groove 23, and then be cut by the cutting head 16 in the cutting groove 23, so as to avoid the position cut by the cutting head 16 being in a warped state, thereby affecting the accuracy of the cutting pattern; at the same time, when the laser cutting machine does not need to use the correction mechanism and the fixing mechanism, the correction mechanism and the fixing mechanism can be removed. Since the laser cutting machine is originally provided with a serrated plate 11, it can be used as a traditional laser cutting machine.

[0068] Embodiment 2: Both of the two Y-axis alignment assemblies include a fixed cylinder 5; the two fixed cylinders 5 are fixedly mounted on both sides of the laser cutter 15;

[0069] Slide rods 51 are slidably connected in the two fixed cylinders 5, and the two slide rods 51 extend into the cutting groove 23; a rotating plate 52 is fixedly connected to one side of the two slide rods 51 extending into the cutting groove 23; the two side end surfaces of the two rotating plates 52 close to the first straightening roller 24 are both rotatably connected to the second straightening roller 53;

[0070] The second straightening roller 53 is fixedly connected to a rotating rod 55 on one side close to the first straightening roller 24; the second straightening roller 53 is provided with a slideway 54 on one side close to the first straightening roller 24 on the top plate 21, and the rotating rod 55 rotates in the slideway 54;

[0071] In this embodiment, the second straightening roller 53 has a rounded corner on one side close to the first straightening roller 24;

[0072] Specifically, since the rotating rod 55 fixedly connected to the second straightening roller 53 rotates in the slideway 54, when the laser cutter 15 drives the cutting head 16 to move down into the cutting groove 23, it will drive the fixed cylinder 5 to move down. At this time, the sliding rod 51 will gradually slide into the fixed cylinder 5. When the Y-axis driving box 14 moves, it will drive the laser cutter 15 to move. The laser cutter 15 will drive the cutting head 16 to move along the Y-axis direction in the cutting groove 23. At the same time, the laser cutter 15 will drive the fixed cylinder 5 to move. The fixed cylinder 5 will drive the second straightening roller 53 through the sliding rod 51 and the rotating plate 52 to move in the cutting groove 23 along the Y-axis direction. At the same time, the rotating rod 55 fixedly connected to the second straightening roller 53 The rod 55 will slide in the slide 54. When the cutting head 16 cuts along the Y-axis direction, the second straightening roller 53 that moves with the laser cutter 15 will first squeeze the plate in the cutting groove 23, so that the part of the plate that is raised in the Y-axis direction can be pressed straight. After the plate is pressed straight, it is then cut by the cutting head 16, so as to further avoid the plate from being raised, which will affect the accuracy of the cut pattern. By setting the first straightening roller 24 and the second straightening roller 53, the cutting head 16 can flatten the plate regardless of whether it is cutting along the X-axis or the Y-axis, so as to further improve the cutting accuracy of the plate.

[0073] More specifically, when the laser cutter 15 moves along the X-axis, it will drive the second straightening roller 53 to move along the X-axis. Since the side of the second straightening roller 53 close to the first straightening roller 24 is rounded, when the second straightening roller 53 moves along the X-axis, the end of the second straightening roller 53 can be prevented from scratching the plate.

[0074] Embodiment 3: Both sides of the drain groove 31 are located in the bottom plate 3 and are rotatably connected to two driven rollers 32;

[0075] An arc groove 33 is provided in the bottom plate 3 below the two driven rollers 32; a driven belt 34 is rotatably connected to the two rotating rollers 43 located on both sides of the drain groove 31;

[0076] In this embodiment, a notch 35 is provided on the bottom plate 3 below the two arc-shaped grooves 33;

[0077] A triangular block 36 is fixedly connected in the notch 35 and is in contact with the driven belt 34. The triangular block 36 is made of rubber material.

[0078] Specifically, since the driven rollers 32 rotating on both sides of the drain groove 31 are rotatably connected with the driven belts 34, when the bottom plate 3 moves along the plate, the driven belts 34 will rotate under the obstruction of the plate, and in this process, the friction between the plate and the bottom plate 3 can be reduced, so that the bottom plate 3 can be moved along the plate better. At the same time, during the rotation of the driven belts 34, impurities between the driven belts 34 and the bottom plate 3 can be taken away, so as to avoid impurities remaining on the upper surface of the bottom plate 3, which will prop up the passing plate, so that the plate appears to be warped;

[0079] Since the triangular block 36 is fixedly connected in the notch 35 , when the driven belt 34 rotates, the triangular block 36 will scrape the driven belt 34 , thereby scraping off impurities adhering to the driven belt 34 and preventing the impurities from following the driven belt 34 and rotating again to above the bottom plate 3 .

[0080] Embodiment 4: The top plate 21 and the bottom plate 3 are fixedly connected to the end surfaces on both sides close to the fixed plate 4 with corresponding L-shaped plates 37;

[0081] The L-shaped plates 37 are all fixedly connected with a wiping layer 38;

[0082] In this embodiment, on the opposite side of the two notches 35, a uniformly arranged sawtooth block 39 is fixedly connected to the bottom surface of the bottom plate 3, and the sawtooth block 39 is meshed with the tooth grooves on the sawtooth plate 11;

[0083] Specifically, since the bottom plate 3 and the end surfaces on both sides of the bottom plate 3 are fixedly connected with the L-shaped plate 37 on which the wiping layer 38 is installed, when the top plate 21 and the bottom plate 3 move along the plate, the wiping layer 38 can first wipe the top and bottom of the plate, thereby preventing impurities from remaining on the plate, thereby affecting the process of cutting and straightening the plate;

[0084] Since a sawtooth block 39 meshing with the sawtooth plate 11 is fixedly connected to the bottom of the base plate 3, when the base plate 3 moves, the sawtooth block 39 can be driven to move, and the moving sawtooth block 39 will gradually mesh with the sawtooth plate 11 below. During the meshing process, impurities attached to the sawtooth plate 11 can be pushed to move, so that these impurities can be removed from the sawtooth plate 11, so there is no need to manually clean the sawtooth plate 11.
