A smart laser cutting device for curved panel parts for ships

Abstract

This invention relates to the field of plate cutting technology and discloses an intelligent laser cutting device for curved panels used in ships. To address the problems of large cutting errors and low cutting accuracy in existing methods, this invention uses a stroke setting module to set the movement value of the moving component, allowing the laser device to be moved to a suitable position. A laser parameter setting module then sets the laser power value and the laser cutting amount. A model plate with the same scale as the plate to be cut is created on the control panel using a model building module. The laser power is set according to the plate thickness. A simulation module is then used to perform simulated cutting, and an error detection module detects the error in the cut plate. If the error is within a reasonable range, an operation synchronization module controls the cutting components to perform actual cutting of the plate. If the error is large, the cutting parameters are adjusted, and simulated cutting continues. This effectively reduces the error risk associated with directly cutting the plate and improves cutting quality.

Description

Technical Field

[0001] This invention relates to the field of plate cutting technology, and in particular to an intelligent laser cutting device for curved plate parts used in ships. Background Technology

[0002] Ship curved panel components refer to metal sheet components with non-planar geometric shapes in parts such as ship hulls and superstructures. They are key components that constitute the streamlined structure and load-bearing frame of ships. The processing of ship curved panel components has long relied on traditional processes such as plasma cutting, flame cutting, and mechanical milling. However, these methods have obvious defects in processing complex curved surfaces. Laser cutting, with its high precision, high flexibility, and low damage characteristics, is perfectly suited to the manufacturing needs of ship curved panel components.

[0003] Chinese patent CN119407372B discloses a laser cutting device, including a base plate. A first groove is formed on the top sidewall of the base plate. A first electric slide rail is fixedly connected to the inner wall of the first groove. A first sliding plate is slidably connected to the top sidewall of the first electric slide rail. A first electric telescopic rod is fixedly connected to the top sidewall of the first sliding plate. When laser cutting M-shaped rock slabs with side edges, the position of the laser cutting gun can be adjusted according to the angles of different parts of the M-shaped rock slab, ensuring that the cutting end of the laser cutting gun is always perpendicular to the surface of the M-shaped rock slab. This facilitates laser cutting of the M-shaped rock slab and avoids uneven cut surfaces caused by workers manually holding the rock slab during cutting, which could affect subsequent installation. It also offers high safety and significantly improves the cutting efficiency and reliability of the device when laser cutting rock slabs.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: In the current intelligent laser cutting device, the workpiece to be cut is placed on the worktable, the size is measured and then cutting begins. This results in the cutting parameters not being adjusted in time, leading to large cutting errors and a decrease in cutting accuracy. Summary of the Invention

If the error is large, the cutting parameters are adjusted, and the simulated cutting continues. This effectively reduces the error risk associated with directly cutting the workpiece and improves the cutting quality. Attached Figure Description

[0019] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0020] Reference Figure 1 and Figure 10 As shown, the present invention provides an intelligent laser cutting device for curved panel parts for ships, including a support frame 1, a worktable 2 disposed on the upper end of the support frame 1, a grid frame 3 disposed on the upper surface of the worktable 2, a control console 4 disposed on one side of the worktable 2, a moving part 6 disposed on the outer surface of the worktable 2, and a cutting component 5 disposed on the outer surface of the moving part 6.

[0021] The console 4 contains a central processing unit 10, which includes a stroke setting module 101. The stroke setting module 101 is connected to a laser parameter setting module 102, which in turn is connected to a model building module 103. The model building module 103 is connected to a simulation module 104, which is connected to an error detection module 105. The error detection module 105 is also connected to an operation synchronization module 106. The stroke setting module 101 sets the movement value of the moving part 6, the laser parameter setting module 102 sets the laser power value and the laser cutting amount, and the model building module 103 creates a model on the console 4 that matches the model to be cut. A model plate of the same scale as the cutting plate is used. The laser power is set according to the thickness of the plate. Then, the simulation module 104 is used to simulate the cutting. The error detection module 105 is used to detect the error of the cut plate. If the error is within a reasonable range, the operation synchronization module 106 controls the cutting component 5 to cut the plate. The plate to be cut is placed on the grid frame 3. The grid frame 3 is used as a support platform, which can effectively reduce the damage of the laser to the support platform. The control console 4 is the control center of the entire device. By moving the moving part 6, the cutting component 5 can be moved along the X-axis to adjust the cutting position. An industrial camera is installed on the surface of the cutting component 5 to detect the cutting process and subsequent error detection.

[0022] Reference Figure 2 As shown, the moving component 6 includes a moving crossbeam 61 mounted on the upper end of the worktable 2, a motor A62 mounted on one side of the moving crossbeam 61, and a displacement rack 63 and a guide rod 64 mounted on one side of the worktable 2. The output end of the motor A62 is equipped with a displacement gear that meshes with the displacement rack 63. The lower end of the moving crossbeam 61 is equipped with a guide block that is slidably connected to the guide rod 64. The upper end of the moving crossbeam 61 is equipped with a moving longitudinal beam 65. The cutting assembly 5 is connected to the moving longitudinal beam 65. When the motor A62 is started, the output end of the motor A62 drives the displacement gear to rotate. Since the displacement gear meshes with the displacement rack 63, the displacement rack 63 moves along the displacement rack 63, thereby driving the moving crossbeam 61 and the moving longitudinal beam 65 to move as a whole. The other end of the moving crossbeam 61 is slidably connected to the other side of the worktable 2 to ensure the overall stability of the moving crossbeam 61 when it moves.

[0023] Reference Figures 3-5As shown, the cutting assembly 5 includes a motor B51 and a motor C53 mounted on the upper end of the moving longitudinal beam 65. A mounting platform 52 is mounted on the lower end of motor B51, and a gear set 511 is mounted on the output end of motor B51. A displacement rod 521 and an extended rack 522 are also mounted on the upper end of the moving longitudinal beam 65. The gear set 511 meshes with the extended rack 522. The mounting platform 52 is slidably connected to the displacement rod 521. A side plate is mounted on one side of the mounting platform 52. Motor C53 is mounted on the upper end of the side plate. A lead screw 54 is mounted on the output end of motor C53. One end of the lead screw 54 is movably connected to the side plate. A pressure block 55 is threaded onto the outer surface of the lead screw 54. A connecting plate 56 is provided on the surface, and a laser device 57 is provided on the outer surface of the connecting plate 56. A positioning rod is also provided on one side of the side plate, and a positioning block is slidably provided on the positioning rod. The positioning block is connected to the connecting plate 56. When the motor C53 is started, its output end drives the lead screw 54 to rotate, which in turn drives the pressure block 55 to move up and down along the lead screw 54, thereby adjusting the Z-axis position of the laser device 57. When the motor B51 is started, its output end drives the gear set 511 to rotate, which in turn causes the gear set 511 to move along the extended rack 522, which in turn causes the mounting platform 52 and the side plate as a whole to move along the extended rack 522, thereby adjusting the Y-axis position of the laser device 57.

[0024] Reference Figure 6 As shown, a cleaning component 8 is provided at the upper end of the moving crossbeam 61. The cleaning component 8 includes a top plate 83 on the upper surface of the moving crossbeam 61 and a cleaning box 81 at the lower end of the top plate 83. An electric push rod A82 is embedded inside the top plate 83. One end of the electric push rod A82 is connected to the cleaning box 81. A return spring and a sponge roller 86 are provided inside the cleaning box 81. One end of the return spring is connected to the inner wall of the cleaning box 81, and the other end of the return spring is connected to the sponge roller 86. During operation, after the plate to be cut is placed on the grid frame 3, the cleaning box 81 is moved by the moving component 6. By controlling the extension and retraction of the electric push rod A82, the surface of the sponge roller 86 contacts the surface of the plate to be cut. As the moving component 6 moves, the sponge roller 86 cleans the surface of the plate to be cut. The cleaning box 81 is tilted and the angle between it and the vertical line of the worktable 2 is 30 degrees.

[0025] Reference Figure 3As shown, sliding grooves 21 are provided on both sides of the workbench 2. An electric push rod B22 and a first clamping block 23 are provided inside the sliding groove 21. One end of the electric push rod B22 is connected to the sliding groove 21, and the other end of the electric push rod B22 is connected to the first clamping block 23. A placement component 7 is provided between the two sets of first clamping blocks 23. During the operation, since the plate to be cut is curved, it cannot be placed stably on the grid frame 3 normally. The placement component 7 can stably place the curved plate to be cut on the grid frame 3. At the same time, the electric push rod B22 can push the first clamping block 23 to move along the sliding groove 21, and then the first clamping block 23 can drive the placement component 7 to move on the upper surface of the grid frame 3.

[0026] Reference Figure 8 and Figure 9As shown, the placement assembly 7 includes a placement box 71 placed on the upper surface of the grid frame 3, a top box 72 disposed at the upper end of the placement box 71, and a curved inclined plate 79 disposed on one side of the placement box 71. A surface groove 791 is formed on the upper surface of the curved inclined plate 79, and a second clamping block 75 is slidably disposed within the surface groove 791. A through groove 792 is formed on one side of the curved inclined plate 79, communicating with the surface groove 791. An extension groove 793 is also formed on one side of the curved inclined plate 79, and an extension block 794 is slidably disposed within the extension groove 793. A lowering plate 796 is placed inside the through groove 792, and the upper surface of the lowering plate 796... Connected to the second clamping block 75, an extended threaded rod 795 is provided through the outer surface of the lowering plate 796 and the extension block 794. A connecting pipe 76 is provided at the upper end of the second clamping block 75. An air blowing pipe 77 is provided at one end of the connecting pipe 76, and a common pipe 74 is provided at the other end of the connecting pipe 76. A branch pipe 73 is provided on one side of the common pipe 74. One end of the branch pipe 73 passes through the outer wall of the top box 72 and is connected to an air pump placed in the top box 72. A rubber arc block 751 and a positioning plate 78 are provided on the inner wall of the second clamping block 75. The air outlet direction of the air blowing pipe 77 is in contact with the surface of the curved inclined plate 79. The rubber arc block 751 and the positioning plate 78. With the curved panel piece to be cut placed on the grid frame 3, the curved surface of the panel piece is placed to fit against the curved surface of the curved inclined plate 79. At this time, the extended threaded rod 795 is screwed on so that one end of the extended threaded rod 795 is not threadedly connected to the extension block 794. Then, the lower plate 796 is moved so that the lower plate 796, along with the second clamping block 75, moves along the surface groove 791 until the second clamping block 75 clamps one end of the curved panel piece and locks one end of the curved panel piece onto the positioning plate 78, preventing one end of the curved panel piece from sliding upwards. At the same time, the rubber arc block 751 prevents the curved panel piece from sliding down. After installation, the panel piece is moved... The extension block 794 is moved along the extension groove 793 until the extension block 794 and the extended threaded rod 795 are in the same vertical plane. Then, the extended threaded rod 795 is screwed to connect one end of the extended threaded rod 795 to the extension block 794, thereby ensuring the stability of the lower plate 796 and the second clamping block 75. At this time, the air pump in the top box 72 is turned on, and the airflow generated enters the common pipe 74, the connecting pipe 76 and the air blowing pipe 77 from the branch pipe 73. Finally, it is sprayed out from the air outlet of the air blowing pipe 77 to the surface of the curved panel, which performs pre-cutting treatment on the surface of the curved panel and improves the subsequent cutting quality.

[0027] Reference Figure 6As shown, the cleaning assembly 8 also includes a collection box 84 disposed at one end of the cleaning box 81. A vacuum cleaner 85 is disposed at the upper end of the collection box 84, and one end of the vacuum cleaner 85 is connected to the collection box 84. The angle between the collection box 84 and the cleaning box 81 is 60 degrees. After the plate to be cut is clamped by the second clamping block 75, as the electric push rod B22 is continuously pushed, the debris on the surface of the plate to be cut will be swept away by the sponge roller 86. Since the sponge roller 86 is inclined relative to the curved plate to be cut, during the process of sweeping the debris on the surface of the curved plate, the debris will move obliquely downward along the sponge roller 86 until it is absorbed into the collection box 84 by the vacuum cleaner 85, thereby improving the cleaning efficiency of the curved plate.

[0028] Reference Figure 7 and Figure 8 As shown, the upper surface of the workbench 2 has an internal groove, and an auxiliary support component 9 is installed inside the internal groove. The auxiliary support component 9 includes an inner support plate 91 installed on the inner wall of the internal groove, and an auxiliary support plate 92 rotatably installed on one side of the inner support plate 91. The upper surface of the auxiliary support plate 92 has a through groove 94, and a center block 95 is installed inside the through groove 94. Electric telescopic support rods 96 are installed on both sides of the center block 95. An outer clamping block 97 is installed at one end of the electric telescopic support rod 96, and the lower end of the outer clamping block 97 is slidably connected to the through groove 94. An electric telescopic rod 921 is rotatably installed on one side of the inner support plate 91, and one end of the electric telescopic rod 921 is connected to the auxiliary support plate 91. 2. Bottom rotation connection: After the curved panel piece to be cut is fixed by the placement component 7, the other end of the curved panel piece is pushed to the built-in groove by the electric push rod B22. Then, the electric telescopic rod 921 is used to make one end of the auxiliary support plate 92 tilt upwards, and the curved panel piece continues to move so that the curved surface of one end of the curved panel piece fits against the auxiliary support plate 92. At the same time, the electric telescopic support rod 96 is activated so that the two sets of outer clamping blocks 97 move closer to each other, thereby achieving positioning and clamping of the curved panel piece. Combined with the fixing of the curved panel piece by the placement component 7, the positioning and clamping of both ends of the entire curved panel piece is achieved, indirectly improving the cutting quality of the curved panel piece.

[0029] The inner wall of the workbench 2 is provided with a sponge board 93, which is located below the auxiliary support plate 92 and is opposite to the auxiliary support plate 92. One end of the sponge board 93 is located directly below the center of the auxiliary support plate 92. After the cutting is completed, the electric telescopic rod 921 retracts, causing the auxiliary support plate 92 to flip together with the cut curved panel piece, so that one end of the curved panel piece faces the inner groove. Since the inner groove is connected to the inside of the workbench 2, the cutting debris remaining on the surface of the curved panel piece is poured into the workbench 2. Since the sponge board 93 is a soft material, it will not obstruct the flipping of the auxiliary support plate 92.

[0030] A support spring 931 is installed inside the sponge plate 93. One end of the support spring 931 is connected to the inner wall of the worktable 2. A rubber protrusion 98 is provided on one side of the outer clamping block 97. During the clamping process of the curved panel piece, the rubber protrusion 98 can increase the clamping friction and prevent slippage. At the same time, after the auxiliary support plate 92 flips over with the cut curved panel piece, the electric telescopic rod 921 continues to extend, so that the auxiliary support plate 92 returns to its original position. During the return process, the curved panel piece on the upper surface of the auxiliary support plate 92 will contact the sponge plate 93, so that the sponge plate 93 can be used to clean the cutting debris remaining on the surface of the curved panel piece and clean the debris into the worktable 2. At the same time, after cleaning, due to the setting of the support spring 931, the sponge plate 93 can be slightly shaken up and down, thereby shaking the debris on the surface of the sponge plate 93 into the worktable 2, completing dual collection. It can not only process the cut panel piece, but also process the sponge plate 93, increasing the usage frequency of the sponge plate 93.

[0031] Working principle: During the operation, the curved panel to be cut is placed on the grid frame 3, and the curved surface of the curved panel is placed to fit the curved surface of the curved inclined plate 79. At this time, the extended threaded rod 795 is screwed so that one end of the extended threaded rod 795 is not threaded to the extension block 794. Then, the lower plate 796 is moved so that the lower plate 796, along with the second clamping block 75, moves along the surface groove 791 until the second clamping block 75 clamps one end of the curved panel and locks one end of the curved panel onto the positioning plate 78 to prevent one end of the curved panel from sliding upward. At the same time, the rubber arc block 751 can prevent the curved panel from sliding down. After installation, the air pump in the top box 72 is turned on. The airflow generated enters the common pipe 74, connecting pipe 76 and air blowing pipe 77 from the branch pipe 73, and finally sprays out from the air outlet of the air blowing pipe 77 to the surface of the curved panel, which performs pre-cutting treatment on the surface of the curved panel and improves the subsequent cutting quality. Secondly, the other end of the curved panel is pushed to the built-in groove by the electric push rod B22. Then, the auxiliary support plate 92 is tilted upward by the electric telescopic rod 921. The curved panel continues to move so that the curved surface of one end of the curved panel fits against the auxiliary support plate 92. At the same time, the electric telescopic support rod 96 is activated so that the two sets of outer clamping blocks 97 move closer to each other, thereby achieving the positioning and clamping of the curved panel. Combined with the fixing of the placement component 7, the positioning and clamping of both ends of the entire curved panel is achieved. Finally, start motor C53, whose output drives lead screw 54 to rotate, which in turn drives pressure block 55 to move up and down along lead screw 54, thereby adjusting the Z-axis position of laser device 57. Start motor B51, whose output drives gear set 511 to rotate, which in turn causes gear set 511 to move along extended rack 522, which in turn causes mounting platform 52 and side plate to move along extended rack 522, thereby adjusting the Y-axis position of laser device 57.
