Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and in particular to an intelligent layout laser cutting device for sheet metal parts. Background Technology

[0002] Laser cutting equipment is a modern industrial device that uses a high-energy-density laser beam as a "light knife" to melt, vaporize, or oxidize metal sheets, thereby achieving precise cutting. Existing laser cutting equipment has an intelligent layout function. Specifically, the scanner on the laser cutting equipment acquires the specifications of the metal sheet, transmits the acquired specifications to the processor, and the processor performs intelligent layout based on the input cutting specifications, so that the metal sheet can be cut and utilized to the maximum extent, improving utilization rate and reducing waste.

[0003] Currently, the main structure of laser cutting equipment includes a perforated support frame for horizontally supporting metal plates. During laser cutting, large-sized metal plates are placed flat on the support frame. The laser cutter on the equipment cuts the metal plate according to the program. During the laser cutting process, molten slag is generated at the cut. This slag is hot and easily adheres to the top and side walls of the perforated support frame. Accumulated slag forms hard metal slag. When this slag accumulates to a certain amount, it affects the levelness of the supported metal plate and also causes slag spatter. The spattered slag adheres to the metal plate, affecting its appearance quality. To solve this problem, the metal slag on the perforated support frame is usually scraped off manually using specialized tools. This cleaning method is not only ineffective but also time-consuming and labor-intensive.

[0004] Therefore, this invention proposes an intelligent layout and laser cutting device for sheet metal parts. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent layout and laser cutting device for sheet metal parts in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smart laser cutting device for sheet metal parts includes a cutting table. A support frame is fixedly installed on the top of the cutting table. The support frame includes a fixed plate and a row of rectangular plates located below the fixed plate. The rectangular plates and the fixed plate are slidably connected vertically. A row of cross-shaped posts arranged along the length direction is fixedly connected to the top of the rectangular plates. A matrix of cross-shaped through holes is provided on the surface of the fixed plate. The cross-shaped posts and cross-shaped through holes correspond one-to-one and are inserted into each other. A control mechanism for controlling the movement of adjacent rectangular plates in different directions and in the same direction is provided below the fixed plate. The control mechanism includes a tray and a drive assembly. A row of trays is arranged below the rectangular plate. The trays are rotatably connected to the fixed plate. One tray is arranged below two adjacent rectangular plates, and one rectangular plate corresponds to one tray. A coaxial support sleeve is fixedly connected to the top of the tray.

A movable frame is slidably connected above the fixed plate. A lifting frame is arranged inside the movable frame. A grinding roller is arranged at the bottom of the lifting frame.

[0008] As a further description of the above technical solution:

[0009] The fixing plate has a matrix of positioning holes on its surface. Wear-resistant columns are fixedly fitted inside the positioning holes. The cross-shaped through holes are opened on the wear-resistant columns. The upper end face of the wear-resistant columns is flush with the upper end face of the fixing plate.

[0010] As a further description of the above technical solution:

[0011] The lifting frame is gantry-shaped and has a protective cover with an opening facing downwards fixedly connected inside. The grinding roller is located inside the protective cover. A negative pressure pipe is fixedly connected to the top of the protective cover. A ring of bristles is glued to the bottom of the protective cover. Two slag discharge troughs are opened on the surface of the fixed plate, respectively near the two ends.

[0012] As a further description of the above technical solution:

[0013] The movable frame is a gantry-type structure. One side of the fixed plate is fixedly connected to a support shaft via an ear plate, and the other side of the fixed plate is rotatably connected to a transmission screw via an ear plate. The bottom of one upright of the movable frame is fixedly connected to a sliding sleeve sleeved outside the support shaft, and the bottom of the other upright of the movable frame is fixedly connected to a transmission screw sleeve sleeved outside the transmission screw.

[0014] As a further description of the above technical solution:

[0015] The two vertical beams on the lifting frame are connected to the horizontal bars on the movable frame. The vertical beams and the horizontal bars are slidably engaged. The top of the horizontal bars is connected to the horizontal beams on the lifting frame via a hydraulic cylinder.

[0016] As a further description of the above technical solution:

[0017] The grinding roller is fixedly connected to the middle of the roller shaft, and the two ends of the roller shaft are set to two vertical beams that pass through the lifting frame. The roller shaft and the vertical beams are rotatably connected. One side of one of the vertical beams is fixedly connected to a drive motor located outside the protective cover. The output shaft of the drive motor is connected to one end of the roller shaft through a belt drive assembly.

[0018] As a further description of the above technical solution:

[0019] Two guide sleeves are fixedly connected to the surface of the rectangular plate, respectively near both ends. A guide post is fixedly connected to the lower end face of the fixed plate and sleeved inside the guide sleeve. The guide post and the guide sleeve are slidably connected. The control mechanism includes a support spring, which is sleeved on the guide post and located between the fixed plate and the rectangular plate.

[0020] As a further description of the above technical solution:

[0021] A coaxial limiting sleeve is fixedly connected to the middle of the tray. A positioning shaft passing through the limiting sleeve is fixedly connected to the lower end face of the fixing plate. The positioning shaft and the limiting sleeve are rotatably connected. The drive assembly includes a transmission shaft, a worm sleeve, and a worm wheel. Two hanging plates near both ends are fixedly connected to the lower end face of the fixing plate. The transmission shaft and the two hanging plates are rotatably connected. A worm wheel is fixedly sleeved on the outside of the support sleeve. The worm sleeve is fixedly sleeved on the transmission shaft and meshes with the worm wheel.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] 1. In this invention, a row of rectangular plates is set below the fixed plate, and a row of cross-shaped piles is fixedly connected to the top wall of the rectangular plates. The cross-shaped piles serve to support the metal plates. The fixed plate has cross-shaped through holes that correspond one-to-one with the cross-shaped piles. When the fixed plate moves up and down, it can drive the cross-shaped piles to move up and down in the cross-shaped through holes. When the cross-shaped piles move up and down in the cross-shaped through holes, the cross-shaped through holes will scrape off the metal slag attached to the side wall of the cross-shaped piles. By setting a grinding roller that can move horizontally and vertically, the metal slag on the top wall of the cross-shaped piles can be scraped off when the grinding roller moves. This setting eliminates the need for manual cleaning of the metal slag on the cross-shaped piles, making the slag removal more efficient and more thorough.

[0024] 2. In this invention, a control mechanism is provided, which includes a tray, a spring, a support sleeve, and trapezoidal protrusions. A row of trays is provided below a row of rectangular plates. A support sleeve is fixedly provided at the bottom of the trays. Two non-circumferentially evenly distributed trapezoidal protrusions are provided at the top of the support sleeve. The bottom of the rectangular plates is connected to rollers adapted to the trapezoidal protrusions through a support column. The trays and the fixed plate are rotatably connected. Thus, when the control trays rotate back and forth at a certain angle, the alternating rectangular plates will move up and down. That is to say, after the metal plate is cut, the metal plate will be supported by a part of the cross-shaped piles, and the other part of the cross-shaped piles will move up and down to clean the slag. This arrangement allows the metal slag to be cleaned at high temperature, thereby greatly reducing the difficulty of cleaning the metal slag on the side wall of the cross-shaped piles.

[0025] 3. In this invention, a non-circumferentially uniformly distributed trapezoidal protrusion is fixedly set on the top of the support sleeve. When the tray drives the support sleeve to rotate at a certain angle, the two rollers above the support sleeve will be on the bottom surface between the two trapezoidal protrusions. This allows the top walls of all the cross-shaped piles to drop to the same height. At this time, when the grinding roller moves horizontally, it can not only clean the metal slag attached to the top wall of the cross-shaped piles, but also clean the metal slag on the fixed plate. This has the advantage of more thorough cleaning of the entire support frame. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0034] Example 1:

[0035] Please see Figures 1-5 A smart laser cutting device for sheet metal parts includes a cutting table 1, a support frame 2 fixedly installed on the top of the cutting table 1, the support frame 2 is used to support the sheet metal parts to be cut, a common carriage is installed on the cutting table 1, a laser support frame that can move laterally is installed on the carriage, and a lifting drive rod that can drive the laser to move up and down is installed on the laser support frame. A laser cutter is installed at the bottom of the lifting drive rod. Under the action of the carriage, the laser support frame and the lifting drive rod, the laser cutter can move in all directions, so that the laser cutter can reach any position in the cutting area, which is convenient for cutting the sheet metal parts held on the support frame 2 according to the layout trajectory.

[0036] In this technical solution, the support frame 2 includes a fixed plate 21 and a row of rectangular plates 22 located below the fixed plate 21. The rectangular plates 22 and the fixed plate 21 are slidably connected vertically. In specific implementation, two guide sleeves 222 are fixedly connected to the surface of the rectangular plates 22, respectively close to both ends. The lower end face of the fixed plate 21 is fixedly connected to a guide post 211 sleeved in the guide sleeve 222. The guide post 211 and the guide sleeve 222 are slidably connected. A row of cross-shaped posts 221 arranged along the length direction is fixedly connected to the top of the rectangular plate 22. The structure of the cross-shaped post 221 is that four ribs are welded around the outer periphery of a cylinder. The thickness of the ribs is 1-1.2mm, and the diameter of the cylinder is 2-2.5mm. The surface of the fixed plate 21 is provided with cross-shaped through holes 3 arranged in a matrix. The cross-shaped posts 221 and the cross-shaped through holes 3 correspond one-to-one and are interlocked. That is to say, the cross-shaped posts 221 can pass through the cross-shaped through holes 3. When the top of the cross-shaped posts 221 is above the fixed plate 21, the matrix arrangement of the cross-shaped posts 221 can effectively support the sheet metal. There is a micro gap between the cross-shaped posts 221 and the cross-shaped through holes 3. When the rectangular plate 22 moves up and down, it can drive the cross-shaped posts 221 to move up and down. When the cross-shaped posts 221 enter and exit the cross-shaped through holes 3, they can scrape off the metal slag attached to their upper sidewalls.

[0037] In specific implementation, the fixing plate 21 has a matrix of positioning holes 213 on its surface. Wear-resistant columns 5 are fixedly fitted inside the positioning holes 213, and cross-shaped through holes 3 are formed on the wear-resistant columns 5. The wear-resistant columns 5 can improve the reliability of scraping off the metal slag attached to the cross-shaped pile 221. The upper end face of the wear-resistant column 5 is flush with the upper end face of the fixing plate 21.

[0038] Below the fixed plate 21 is a control mechanism 4 for controlling the movement of adjacent rectangular plates 22 in different directions and in the same direction. The control mechanism 4 includes a support spring 41, which is sleeved on the guide post 211 and located between the fixed plate 21 and the rectangular plates 22. The function of the support spring 41 is to provide elastic thrust for the rectangular plates 22 to move downward. The aforementioned different directions refer to the situation where one rectangular plate 22 rises while the other rectangular plate 22 falls. The aforementioned same-direction movement refers to the situation where all rectangular plates 22 can rise and fall simultaneously. When adjacent rectangular plates 22 do not rise and fall simultaneously, the metal slag attached to the side wall of the cross-shaped post 221 can be peeled off using the cross through hole 3. In other words, during the laser cutting process, the adjacent rectangular plates 22 can be controlled to not rise and fall simultaneously. Since the metal slag on the cross-shaped post 221 is in an uncured state, it can be easily peeled off.

[0039] Specifically, the control mechanism 4 includes a tray 42 and a drive group 43. A row of trays 42 is arranged below a row of rectangular plates 22. The trays 42 and the fixed plate 21 are rotatably connected. Specifically, a coaxial limiting sleeve 422 is fixedly connected to the middle of the tray 42. A positioning shaft 212 passing through the limiting sleeve 422 is fixedly connected to the lower end face of the fixed plate 21. The positioning shaft 212 and the limiting sleeve 422 are rotatably connected. A tray 42 is positioned below two adjacent rectangular plates 22, with one rectangular plate 22 corresponding to one tray 42. A coaxial support sleeve 421 is fixedly connected to the top of the tray 42. Two non-circumferentially evenly distributed trapezoidal protrusions 4211 are fixedly connected to the top wall of the support sleeve 421. The bottom of the rectangular plate 22 is connected to rollers 2231 adapted to the trapezoidal protrusions 4211 via a support column 223. In actual use, when the tray 42 rotates, the rollers 2231 will roll on the top wall of the trapezoidal protrusions 4211 and also roll into the plane between the two trapezoidal protrusions 4211 on the support sleeve 421. The two non-circumferentially evenly distributed trapezoidal protrusions 4211 are located on two rays with an included angle of 120 degrees emanating from the center of the support sleeve 421 in the radial direction. When the two rollers 2231 above the tray 42 are respectively located on the planes on both sides of the trapezoidal convex 4211, all the cross-shaped posts 221 will be at the same height and the top wall of the cross-shaped posts 221 will be flush with the upper surface of the fixing plate 21. When one roller 2231 above the tray 42 is located on the top wall of the trapezoidal convex 4211 and the other roller 2231 is located on the bottom surface of one side of the trapezoidal convex 4211, the cross-shaped posts 221 on one of the two adjacent rectangular plates 22 are in the position of supporting sheet metal parts, and the top wall of the cross-shaped posts 221 on the other rectangular plate 22 is flush with the upper surface of the fixing plate 21.

[0040] The drive unit 43 is located below a row of rectangular plates 22 and is used to control all the trays 42 to rotate synchronously in the same direction. By controlling the rotation angle of the trays 42, the switching between the movement of adjacent rectangular plates 22 in different directions and in the same direction can be realized.

[0041] Specifically, the drive assembly 43 includes a drive shaft 431, a worm sleeve 432, and a worm wheel 433. Two hanging plates 214 near both ends are fixedly connected to the lower end face of the fixed plate 21. The drive shaft 431 and the two hanging plates 214 are rotatably connected. The worm wheel 433 is fixedly sleeved on the outside of the support sleeve 421. The worm sleeve 432 is fixedly sleeved on the drive shaft 431 and meshes with the worm wheel 433. One worm sleeve 432 corresponds to one worm wheel 433. When the drive shaft 431 rotates, it can drive all the worm wheels 433 to rotate synchronously and in the same direction through the worm sleeve 432 on it, thereby driving all the trays 42 to rotate synchronously and in the same direction. In use, a servo motor is fixedly installed on one side of one of the hanging plates 214. The output shaft of the servo motor is fixedly connected to one end of the drive shaft 431.

[0042] A movable frame 6 is slidably connected above the fixed plate 21. A lifting frame 7 is installed inside the movable frame 6. The movable frame 6 can drive the lifting frame 7 to move horizontally. In specific implementation, the movable frame 6 is a gantry structure. One side of the fixed plate 21 is fixedly connected to a support shaft 216 through an ear plate 1. The other side of the fixed plate 21 is rotatably connected to a transmission screw 101 through an ear plate 2. The bottom of one upright 61 on the movable frame 6 is fixedly connected to a sliding sleeve 611 sleeved outside the support shaft 216. The bottom of the other upright 61 on the movable frame 6 is fixedly connected to a transmission sleeve 612 sleeved outside the transmission screw 101. When the transmission screw 101 rotates, it can drive the entire movable frame 6 to move through the transmission sleeve 612. In use, a servo motor 2 is fixedly installed on one side of one of the ear plates 2. The output shaft of the servo motor 2 is fixedly connected to one end of the transmission screw 101. The servo motor 2 provides driving force to the rotation of the transmission screw 101. A grinding roller 8 is installed at the bottom of the lifting frame 7. The lifting frame 7 can control the height of the grinding roller 8. Specifically, the two vertical beams 71 on the lifting frame 7 are set to pass through the horizontal bar 62 on the moving frame 6. The vertical beams 71 and the horizontal bar 62 are slidably engaged. The top of the horizontal bar 62 is connected to the horizontal beam 72 on the lifting frame 7 through the hydraulic cylinder 102. The hydraulic cylinder 102 adopts a structure with servo control function. When the hydraulic cylinder 102 is activated, it can drive the lifting frame 7 to move up and down through the horizontal beam 72. When all the cross-shaped piles 221 are lowered to the lowest point and at the same height, the grinding roller 8 can grind away the metal slag on the top of all the cross-shaped piles 221 by translating and rotating at the same time.

[0043] Furthermore, the upper end face of the wear-resistant column 5 is flush with the upper end face of the fixing plate 21, controlling the top wall of the cross-shaped pile 221 (before the metal slag adheres) to be flush with the upper end face of the wear-resistant column 5. When the grinding roller 8 descends to the grinding station and then moves horizontally, the rotation of the grinding roller 8 can not only clean the metal slag at the top of the cross-shaped pile 221, but also grind away the metal debris accumulated on the upper end face of the fixing plate 21. This setting can effectively prevent slag from being trapped in the cross through hole 3.

[0044] In this embodiment, the lifting frame 7 is a door-shaped structure with a downward-facing protective cover 105 fixedly connected inside. The grinding roller 8 is located inside the protective cover 105. The function of the protective cover 105 is to prevent dust pollution during grinding. A negative pressure pipe 1051 is fixedly connected to the top of the protective cover 105. During use, the negative pressure pipe 1051 is connected to an external negative pressure exhaust pipe through a flexible hose. The purpose is to collect the impurities generated during grinding and transmit them to the dust removal and filtration system.

[0045] The protective cover 105 has a ring of bristles 9 bonded to its bottom. The fixed plate 21 has two slag-collecting grooves 215 located near both ends. When the grinding roller 8 is in the grinding position, the bristles 9 abut against the upper surface of the fixed plate 21. As the protective cover 105 moves, the bristles 9 sweep away some non-adherent impurities on the fixed plate 21, and these swept impurities fall through the slag-collecting grooves 215. It should be noted that the bristles 9 also prevent dust from spilling out of the protective cover 105.

[0046] In this embodiment, a roller shaft 81 is fixedly connected to the middle of the grinding roller 8. The two ends of the roller shaft 81 are provided with two vertical beams 71 that pass through the lifting frame 7. The roller shaft 81 and the vertical beams 71 are rotatably connected. A drive motor 103 located outside the protective cover 105 is fixedly connected to one side of one of the vertical beams 71. The drive motor 103 is also a model with servo control function. The output shaft of the drive motor 103 is connected to one end of the roller shaft 81 through the belt drive group 104. The drive motor 103 provides driving force to the rotation of the roller shaft 81. After the drive motor 103 is started, it can drive the grinding roller 8 to rotate.

[0047] Working principle: Before use, control all rectangular plates 22 to their highest position. At this time, all cross-shaped posts 221 are in the state of penetrating the cross-shaped through holes 3, and the top wall of the cross-shaped posts 221 is higher than the top wall of the fixed plate 21. During use, place the entire metal plate magnetic chuck above the fixed plate 21. At this time, the top of all cross-shaped posts 221 is in contact with the bottom wall of the metal plate, and the metal plate is horizontally supported. Start the intelligent layout program in the processor corresponding to the laser cutter. The laser cutter begins to move in all directions according to the program settings to laser cut the metal plate. After the metal plate is cut, some of the metal slag produced by cutting will adhere to the side and top walls of the cross-shaped posts 221, and other metal slag will adhere to the upper surface of the fixed plate 21. After the metal plate is cut and before it is removed, the drive shaft 431 is rotated by a servo motor. The drive shaft 431 drives the tray 42 to rotate and move by an angle through the meshing of the worm sleeve 432 and the worm wheel 433. As a result, the support sleeve 421 will rotate by a certain angle. At this time, one roller 2231 above the support sleeve 421 is still on the top wall of the trapezoidal protrusion 4211, and the other roller 2231 will roll down from the corresponding trapezoidal protrusion 4211. The rectangular plate 22 corresponding to the roller 2231 that is falling will fall under the push of the support spring 41. At this time, the cross-shaped post 221 on the falling rectangular plate 22 will move along the cross through hole 3. The wear-resistant column 5 will scrape off the metal slag that is attached to the side wall of the cross-shaped post 221 and is in a high-temperature state. Then, the control... The drive shaft 431 is reversed by a certain angle, causing the descending roller 2231 to reset. The corresponding rectangular plate 22 drives the cross-shaped post 221 on it to reset. At the same time, the adjacent roller 2231 will descend, and the rectangular plate 22 corresponding to the descending roller 2231 will drive the corresponding cross-shaped post 221 to descend. The metal slag on the side wall of the cross-shaped post 221 is scraped off by the wear-resistant column 5, thereby cleaning the metal slag on the side wall of all the cross-shaped posts 221. Then, the cut metal plate is removed using a magnetic chuck. The drive shaft 431 is then rotated to another angle. At this time, the two rollers 2231 above the support sleeve 421 will be located on the bottom surface between the two trapezoidal protrusions 4211, and the rectangular plate 22 corresponding to the two rollers 2231 will descend to... At the same height, the top walls of all the cross-shaped piles 221 descend to the same height. Then, the lifting frame 7 is lowered by the hydraulic cylinder 102 through the crossbeam 72. The lower wall of the grinding roller 8 is in near contact with the top wall of the fixed plate 21. Then, the drive motor 103 is started. Under the transmission of the belt drive group 104, the grinding roller 8 rotates at high speed. Then, the transmission screw 101 is controlled to rotate. Under the transmission of the transmission sleeve 612, the moving frame 6 drives the rotating grinding roller 8 to move along the upper end surface of the fixed plate 21. When the grinding roller 8 passes over the metal slag attached to the upper end surface of the fixed plate 21, the metal slag is ground off. When the grinding roller 8 passes over the metal slag attached to the top of the cross-shaped pile 221, the metal slag is ground off. The metal shavings ground off are drawn away by the negative pressure pipe 1051.This allows for the removal of metal slag from the upper surface of the fixing plate 21 and the top wall of the cross-shaped pile 221, thereby completing the comprehensive cleaning of metal slag on the support frame 2.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
