Description

Technical Field

[0001] This invention belongs to the field of laser cutting machine technology, and specifically relates to a laser cutting machine for processing moisture-proof doors. Background Technology

[0002] A laser cutting machine uses a laser beam emitted from a laser source, which is focused into a high-power-density laser beam through an optical path system. This laser beam irradiates the surface of the workpiece, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas, coaxial with the beam, blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a kerf is eventually formed in the material, thus achieving the purpose of cutting.

[0003] A search revealed that Chinese Patent Publication No. CN222113874U discloses a laser cutting machine for door panel processing, relating to the field of laser cutting equipment technology. The machine includes a cutting table, a processing groove fixedly mounted on the top of the cutting table, a conveyor belt movably mounted on the inner wall of the processing groove, a fixed frame fixedly mounted on the other end of the top of the cutting table, a control board fixedly mounted on one side of the fixed frame, and a laser cutting machine body movably mounted on the top of the fixed frame. Slide rails are provided on both sides of the inner wall of the fixed frame, and an electric push column is provided at one end of the inner wall of each slide rail. This application solves the problem of increased labor and reduced worker safety caused by the need for manual adjustment of the workpiece position during laser cutting, achieved through the cooperation of the electric push column, adjusting plate, electric telescopic column, and clamping plate. It achieves a clamping and sliding function, facilitating automatic adjustment of the workpiece position, saving workpieces, and increasing the safety performance of the device.

[0004] However, the equipment still has the following defects: Although it can automatically adjust the position of the processed parts, saving processed parts and increasing the safety performance of the device, it cannot properly store the laser-cut metal sheets according to the processing requirements of the metal moisture-proof door. This causes the cut metal sheets to be prone to high temperature, which damages the wood inside the composite moisture-proof door, causing the wood to become scorched and increasing the difficulty of sealing the edge of the moisture-proof door. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a laser cutting machine for processing moisture-proof doors, comprising a cutting table assembly; a cutting machine assembly is mounted on one side of the top of the cutting table assembly, and clamping assemblies are horizontally slidably connected to both side walls of the cutting machine assembly; marking assemblies are provided on the other two side walls of the cutting machine assembly; and the two sets of clamping assemblies and two sets of marking assemblies within the cutting machine assembly are staggered; a composite moisture-proof door is horizontally driven connected to the top of the cutting table assembly; the edges of the side walls of the composite moisture-proof door are tumbled and fitted with the clamping assemblies; the clamping assemblies are used to detect and analyze the metal layer, wood core material, and adhesive layer inside the composite moisture-proof door; the marking assemblies are tumbled and fitted to the top of the composite moisture-proof door, forming a cutting area for the composite moisture-proof door between the two sets of clamping assemblies and the two sets of marking assemblies, thereby increasing the stability of the cutting machine assembly in cutting the composite moisture-proof door.

[0006] Furthermore, the cutting table assembly includes a conveyor plate; the top of the conveyor plate is provided with several sets of adjustment grooves, and the bottom of the inner wall of each of the several sets of adjustment grooves is slidably connected to two sets of cylinders, and the side of each set of cylinders away from the output end is threadedly connected to a lead screw, one end of which is rotatably connected to one side of the inner wall of the adjustment groove.

[0007] Furthermore, the other end of the lead screw is connected to the output end of a servo motor, and the side of the servo motor away from the output end is fixedly connected to the other side of the inner wall of the adjustment groove. Both sides of the conveying plate are fixedly connected to bosses, and the inner walls of both bosses are provided with several sets of mounting holes. Conveying rollers are rotatably connected in the several sets of mounting holes. The output end of the cylinder passes through the gap between every two sets of conveying rollers and extends to the top of the conveying plate.

[0008] Furthermore, the cutting machine assembly includes a cutting frame; the top of the cutting frame is provided with an adjustment cavity, and a first horizontal slide is horizontally installed on both sides of the inner wall of the adjustment cavity, and the output ends of the first horizontal slides on both sides are driven to a lifting slide, the output ends of the lifting slides are driven to a second horizontal slide, and the output ends of the second horizontal slides are driven to a laser cutting machine body.

[0009] Furthermore, several sets of first air pumps are embedded in the bottom of the laser cutting machine body, and the output ends of the several sets of first air pumps are all connected to bent air nozzles. The bent air nozzles are used to transfer the gas delivered by the first air pumps to the cutting position of the laser cutting machine body and the composite moisture-proof door. While cooling the laser cutting machine body after use, it can also keep the cutting position of the composite moisture-proof door clean. Marking component mounting holes are opened on the outer wall of the cutting frame near the corners. Two sets of guide grooves are opened on the outer wall of the cutting frame, and the two sets of guide grooves are located at the bottom of the marking component mounting holes.

[0010] Furthermore, the clamping assembly includes a linkage plate; the linkage plate is slidably attached to the inner wall of the guide groove, and a vertical plate is fixedly connected to one end of the linkage plate, and a number of mounting cavities are opened on the outer wall of the vertical plate, and a linkage wheel is rotatably connected in each of the number of mounting cavities.

[0011] Furthermore, the outer wall of the linkage wheel is provided with separation plates near both ends. As the linkage plate moves towards the composite moisture-proof door, the separation plates on both sides can separate the metal layer and the wooden core material at the edge of the side wall of the composite moisture-proof door. After the laser cutting machine body cuts through the metal layer of the composite moisture-proof door, the separation plates can protect the wooden core material and prevent the high-temperature laser from damaging the wooden core material.

[0012] Furthermore, a gas guide box is fixedly connected to the inner wall of the vertical plate and the side near the linkage plate. A positioning tube is embedded in the vertical plate. One end of the positioning tube passes through the linkage plate and extends into the gas guide box. A second air pump for delivering airflow into the gas guide box is installed on the positioning tube.

[0013] Furthermore, the other end of the positioning tube passes through the center of the central axis of the linkage wheel, and is used to position the linkage wheel during rotation. A thickness detector is embedded in the outer wall of the vertical plate on the side close to the direction of movement of the composite moisture-proof door. Several sets of high-definition cameras are embedded in the outer wall of the vertical plate on the side away from the gas guide box, which are used to visually inspect the metal layer, wooden core material and adhesive layer at the edge of the composite moisture-proof door.

[0014] Furthermore, a hinge seat is embedded in the outer wall of the linkage plate on the side away from the vertical plate. The output end of the telescopic rod is rotatably connected to the hinge seat. A linkage rod is fixedly connected to the side of the telescopic rod away from the output end. Both ends of the linkage rod are rotatably connected to two sets of first positioning blocks. The first positioning blocks are fixedly connected to the outer wall of the cutting frame. A stepper motor for driving the linkage rod to rotate is embedded in the outer wall of the first positioning block. The rotation of the output end of the stepper motor drives the linkage plate to move horizontally to different positions in the guide groove. This serves to clamp the edges of the composite moisture-proof door and separate and protect the structural layers, using several sets of linkage wheels and separation plates.

[0015] The beneficial effects of this invention are:

[0016] 1. The composite moisture-proof door is horizontally conveyed through the top of the cutting table assembly. The side edge of the composite moisture-proof door rolls and fits against the clamping assembly. While limiting and guiding, the clamping assembly detects and analyzes the internal metal layer, wood core material, and adhesive layer of the composite moisture-proof door. The marking assembly is attached to the top surface of the composite moisture-proof door to complete the cutting mark positioning. The two sets of clamping assemblies and the two sets of marking assemblies work together to enclose and define a stable cutting area, effectively constraining the displacement and deviation of the board material, thereby improving the overall stability and processing accuracy of the cutting machine assembly for the composite moisture-proof door cutting operation.

[0017] 2. A servo motor drives a lead screw to rotate, adjusting the distance between two sets of cylinders in the adjusting groove to match the width of the composite moisture-proof door to be cut, thus supporting the bottom edge of the composite moisture-proof door. Simultaneously, a stepper motor drives a linkage rod to rotate, which in turn drives a linkage plate to move within a guide groove via a telescopic rod and hinge seat. This causes the linkage wheel on the vertical plate to fit against the side wall of the composite moisture-proof door. A separating plate separates the metal layer from the wood core material of the side wall of the composite moisture-proof door. A high-definition camera and a thickness detector respectively inspect the edge structure and thickness of the composite moisture-proof door, completing the positioning and protection preparation before feeding. The conveying roller on the boss rotates, transporting the composite moisture-proof door to the cutting position.

[0018] 3. Through the coordinated action of the first horizontal slide, the lifting slide, and the second horizontal slide, the laser cutting machine body is driven to move to the set cutting position to cut the composite moisture-proof door. During the cutting process, the first air pump delivers gas through the curved air nozzle, which cools the laser cutting machine body on the one hand and cleans up the debris at the cutting position of the composite moisture-proof door on the other hand, keeping the cutting surface clean. At the same time, the linkage wheel continuously adheres to the side wall of the composite moisture-proof door, the separation plate continuously protects the wooden core material to avoid damage caused by the high temperature laser, the positioning tube positions the rotating linkage wheel, and the second air pump delivers airflow to the gas guide box through the positioning tube to help ensure the stable operation of the linkage wheel.

[0019] 4. The bending rod rotates to drive the pressure roller to press the composite moisture-proof door, positioning it between the conveying roller and the pressure roller. The spacing between the two sets of inkjet printers is adjusted by rotating the threaded rod, and the inkjet printers mark the cutting position of the composite moisture-proof door. After marking, the output end of the cylinder lifts the composite moisture-proof door, automatically separating it from the cut scrap. Then, the conveying roller continues to rotate, driving the scrap to be automatically unloaded, completing one cutting operation. The above steps can be repeated for continuous operation.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] This invention provides a laser cutting machine for processing moisture-proof doors, including a cutting table assembly 1; for example, such as... Figure 1 and Figure 2 As shown.

[0026] A cutting machine assembly 2 is installed on one side of the top of the cutting table assembly 1, and clamping assemblies 3 are horizontally slidably connected to both sides of the cutting machine assembly 2. Marking assemblies 4 are provided on the other two sides of the cutting machine assembly 2, and the two sets of clamping assemblies 3 and the two sets of marking assemblies 4 inside the cutting machine assembly 2 are staggered. A composite moisture-proof door 5 is horizontally driven connected to the top of the cutting table assembly 1. The edges of the two sides of the composite moisture-proof door 5 are rolled and fitted with the clamping assemblies 3. The clamping assemblies 3 are used to detect and analyze the metal layer, wood core material and adhesive layer inside the composite moisture-proof door 5. The marking assemblies 4 are rolled and fitted to the top of the composite moisture-proof door 5, so that the cutting area of ​​the composite moisture-proof door 5 is formed between the two sets of clamping assemblies 3 and the two sets of marking assemblies 4, which increases the stability of the cutting machine assembly 2 in cutting the composite moisture-proof door 5.

[0027] Specifically, the top of the cutting table assembly 1 horizontally conveys the composite moisture-proof door 5. The side edge of the composite moisture-proof door 5 rolls and adheres to the clamping assembly 3. While limiting and guiding, the clamping assembly 3 detects and analyzes the internal metal layer, wood core material and adhesive layer of the composite moisture-proof door 5. The marking assembly 4 adheres to the top surface of the composite moisture-proof door 5 to complete the cutting mark positioning. The two sets of clamping assemblies 3 and the two sets of marking assemblies 4 cooperate to enclose and delineate a stable cutting area, effectively constraining the displacement and deviation of the board, thereby improving the overall stability and processing accuracy of the cutting machine assembly 2 in the cutting operation of the composite moisture-proof door 5.

[0028] The cutting table assembly 1 includes a conveyor plate 11; for example, such as Figure 3 As shown.

[0029] The top of the conveyor plate 11 is provided with several sets of adjustment grooves 12, and the bottom of the inner wall of each of the several sets of adjustment grooves 12 is slidably connected to two sets of cylinders 13. A lead screw 17 is threadedly connected to the side of each cylinder 13 away from the output end. One end of the lead screw 17 is rotatably connected to one side of the inner wall of the adjustment groove 12, and the other end of the lead screw 17 is drively connected to the output end of a servo motor. The side of the servo motor away from the output end is fixedly connected to the other side of the inner wall of the adjustment groove 12. Both sides of the conveyor plate 11 are fixedly connected to bosses 14, and the inner walls of both bosses 14 are provided with several... The dry assembly mounting holes 15 are connected to several sets of conveying rollers 16. The output end of the cylinder 13 passes through the gap between every two sets of conveying rollers 16 and extends to the top of the conveying plate 11. During the rotation of the lead screw 17 driven by the output end of the servo motor, the distance between the two sets of cylinders 13 is adjusted to support the bottom edge of the composite moisture-proof door 5 of different widths after cutting. When the output end of the two sets of cylinders 13 lifts the composite moisture-proof door 5, the composite moisture-proof door 5 is automatically separated from the cut scrap material, which is convenient to drive the scrap material to be automatically unloaded again by the rotation of several sets of conveying rollers 16.

[0030] The cutting machine assembly 2 includes a cutting frame 21; for example, such as Figure 4 and Figure 5 As shown.

[0031] The top of the cutting frame 21 has an adjustment cavity 22. A first horizontal slide 23 is horizontally installed on both sides of the inner wall of the adjustment cavity 22. The output ends of both first horizontal slides 23 are drivenly connected to a lifting slide 24. The output ends of the lifting slides 24 are drivenly connected to a second horizontal slide 25. The output ends of the second horizontal slides 25 are drivenly connected to the laser cutting machine body 26. Several sets of first air pumps 29 are embedded in the bottom of the laser cutting machine body 26, and the output ends of the several sets of first air pumps 29 are all connected to an... Equipped with a curved air nozzle 210, the gas delivered by the first air pump 29 is transmitted to the laser cutting machine body 26 and the cutting position of the composite moisture-proof door 5 through the curved air nozzle 210. While cooling the laser cutting machine body 26 after use, it can also keep the cutting position of the composite moisture-proof door 5 clean. Marking component mounting holes 27 are opened on the outer wall of the cutting frame 21 near the corner. Two sets of guide grooves 28 are opened on the outer wall of the cutting frame 21, and the two sets of guide grooves 28 are located at the bottom of the marking component mounting holes 27.

[0032] The clamping assembly 3 includes a linkage plate 31; for example, such as Figure 6 and Figure 7 As shown.

[0033] The linkage plate 31 is slidably attached to the inner wall of the guide groove 28, and a vertical plate 32 is fixedly connected to one end of the linkage plate 31. The outer wall of the vertical plate 32 is provided with several sets of mounting cavities 33, and a linkage wheel 34 is rotatably connected in each set of mounting cavities 33. Separation plates 35 are provided on the outer wall of the linkage wheel 34 near both ends. When the linkage plate 31 approaches the composite moisture-proof door 5, the separation plates 35 on both sides can separate the metal layer and the wood core material at the edge of the side wall of the composite moisture-proof door 5. After the laser cutting machine body 26 cuts through the metal layer of the composite moisture-proof door 5, the separation plates 35 can protect the wood core material and prevent the high temperature laser from damaging the wood core material. A gas guide box 36 is fixedly connected to the inner wall of the vertical plate 32 and the side near the linkage plate 31. A positioning tube 37 is embedded in the vertical plate 32. One end of the positioning tube 37 passes through the linkage plate 31 and extends into the gas guide box 36. A second air pump 38 for delivering airflow into the gas guide box 36 is installed on the positioning tube 37. The other end of the positioning tube 37 passes through the center of the central axis of the linkage wheel 34 and is used to position the linkage wheel 34 during rotation. A thickness detector 39 is embedded in the outer wall of the vertical plate 32 and the side near the moving direction of the composite moisture-proof door 5. Several sets of high-definition cameras 310 are embedded in the outer wall of the vertical plate 32 and the side away from the gas guide box 36 for visual inspection of the metal layer, wood core material and adhesive layer at the edge of the composite moisture-proof door 5. A hinge seat 311 is embedded in the outer wall of the linkage plate 31 on the side away from the vertical plate 32. The output end of the telescopic rod 312 is rotatably connected to the hinge seat 311. A linkage rod 313 is fixedly connected to the side of the telescopic rod 312 away from the output end. Both ends of the linkage rod 313 are rotatably connected to two sets of first positioning blocks 314. The first positioning blocks 314 are fixedly connected to the outer wall of the cutting frame 21. A stepper motor for driving the linkage rod 313 to rotate is embedded in the outer wall of the first positioning blocks 314. The rotation of the output end of the stepper motor drives the linkage plate 31 to move horizontally to different positions in the guide groove 28. This serves to clamp the edge of the composite moisture-proof door 5 and separate and protect the structural layer using several sets of linkage wheels 34 and separation plates 35.

[0034] The marking component 4 includes a bent pipe rod 41; for example, such as Figure 8 As shown.

[0035] Both ends of the bent tube rod 41 are rotatably connected to the marking component mounting holes 27. A pressure roller 42 is rotatably connected to the center of the central axis of the bent tube rod 41. Two sets of inkjet printers 43 are slidably connected to the outer wall of the bent tube rod 41. A second positioning block 44 is fixedly connected to one side of the outer wall of each inkjet printer 43. A threaded rod 45 is horizontally threaded onto the second positioning block 44. A third positioning block 46 is rotatably connected to both ends of the threaded rod 45. The third positioning block 46 is embedded in the bent tube rod 41. The rotation of the bent tube rod 41 drives the pressure roller 42 to press the composite moisture-proof door 5 at different angles, so that the composite moisture-proof door 5 is positioned between the conveying roller 16 and the pressure roller 42. The rotation of the threaded rod 45 can also be used to adjust the spacing between the two inkjet printers 43, so as to adjust the position marking to be cut according to the cutting requirements.

[0036] Specifically, the servo motor drives the lead screw 17 to rotate, adjusting the distance between the two sets of cylinders 13 in the adjusting groove 12 to match the width of the composite moisture-proof door 5 to be cut, thus supporting the bottom edge of the composite moisture-proof door 5. At the same time, the stepper motor drives the linkage rod 313 to rotate, and through the telescopic rod 312 and the hinge seat 311, the linkage plate 31 moves in the guide slide 28, so that the linkage wheel 34 on the vertical plate 32 fits against the side wall of the composite moisture-proof door 5. The separating plate 35 separates the metal layer of the side wall of the composite moisture-proof door 5 from the wood core material. The high-definition camera 310 and the thickness detector 39 respectively detect the edge structure and thickness of the composite moisture-proof door 5, completing the positioning and protection preparation before feeding. The conveying roller 16 on the boss 14 rotates, conveying the composite moisture-proof door 5 to the cutting position.

[0037] After the composite moisture-proof door 5 is positioned, the first horizontal slide 23, the lifting slide 24, and the second horizontal slide 25 work together to drive the laser cutting machine body 26 to move to the set cutting position to cut the composite moisture-proof door 5. During the cutting process, the first air pump 29 delivers gas through the curved air nozzle 210 to cool the laser cutting machine body 26 and clean the debris at the cutting position of the composite moisture-proof door 5, keeping the cutting surface clean. At the same time, the linkage wheel 34 continuously adheres to the side wall of the composite moisture-proof door 5, the separation plate 35 continuously protects the wooden core material to avoid damage caused by the high temperature laser, the positioning tube 37 positions the rotating linkage wheel 34, and the second air pump 38 delivers airflow to the gas guide box 36 through the positioning tube 37 to help ensure the stable operation of the linkage wheel 34.

[0038] After cutting, the bending rod 41 rotates to drive the pressure roller 42 to press the composite moisture-proof door 5, positioning the composite moisture-proof door 5 between the conveying roller 16 and the pressure roller 42. The spacing between the two sets of inkjet printers 43 is adjusted by rotating the threaded rod 45, and the inkjet printers 43 mark the cutting position of the composite moisture-proof door 5. After marking, the output end of the cylinder 13 lifts the composite moisture-proof door 5, so that the composite moisture-proof door 5 is automatically separated from the cut scrap. Then the conveying roller 16 continues to rotate, driving the scrap to be automatically unloaded, completing one cutting operation. The above steps can be repeated for continuous operation.

[0039] The working principle of a laser cutting machine for processing moisture-proof doors, as proposed in this embodiment of the invention, is as follows: Step 1: Positioning Adjustment and Feeding Support. First, the servo motor drives the lead screw 17 to rotate, adjusting the distance between the two sets of cylinders 13 in the adjustment groove 12 to match the width of the composite moisture-proof door 5 to be cut, thus supporting the bottom edge of the composite moisture-proof door 5. At the same time, the stepper motor drives the linkage rod 313 to rotate, which drives the linkage plate 31 to move in the guide slide 28 through the telescopic rod 312 and the hinge seat 311, so that the linkage wheel 34 on the vertical plate 32 fits against the side wall of the composite moisture-proof door 5. The separating plate 35 separates the metal layer of the side wall of the composite moisture-proof door 5 from the wood core material. The high-definition camera 310 and the thickness detector 39 respectively detect the edge structure and thickness of the composite moisture-proof door 5, completing the positioning and protection preparation before feeding. The conveying roller 16 on the boss 14 rotates, conveying the composite moisture-proof door 5 to the cutting position.

[0040] Step 2: Cutting and Cleaning / Cooling. After the composite moisture-proof door 5 is positioned, the first horizontal slide 23, the lifting slide 24, and the second horizontal slide 25 work together to drive the laser cutting machine body 26 to move to the set cutting position to cut the composite moisture-proof door 5. During the cutting process, the first air pump 29 delivers gas through the curved air nozzle 210 to cool the laser cutting machine body 26 and clean the debris at the cutting position of the composite moisture-proof door 5, keeping the cutting surface clean. At the same time, the linkage wheel 34 continuously contacts the side wall of the composite moisture-proof door 5, the separation plate 35 continuously protects the wooden core material to avoid damage caused by the high-temperature laser, the positioning tube 37 positions the rotating linkage wheel 34, and the second air pump 38 delivers airflow to the gas guide box 36 through the positioning tube 37 to help ensure the stable operation of the linkage wheel 34.

[0041] Step 3: Marking and material unloading separation. After cutting, the bending rod 41 rotates to drive the pressure roller 42 to press the composite moisture-proof door 5, positioning the composite moisture-proof door 5 between the conveying roller 16 and the pressure roller 42. The spacing between the two sets of inkjet printers 43 is adjusted by rotating the threaded rod 45, and the inkjet printers 43 mark the cutting position of the composite moisture-proof door 5. After marking, the output end of the cylinder 13 lifts the composite moisture-proof door 5, automatically separating the composite moisture-proof door 5 from the cut scrap. Then the conveying roller 16 continues to rotate, driving the scrap to be automatically unloaded, completing one cutting operation. The above steps can be repeated for continuous operation.
