Description

Technical Field

[0001] This invention relates to the field of intelligent conveyor technology, specifically to an intelligent conveyor for laser cutting. Background Technology

[0002] Laser cutting uses a high-power-density laser beam to irradiate the material being cut, quickly heating it to its vaporization temperature and causing it to evaporate and form a hole. As the beam moves across the material, the holes continuously form a very narrow kerf, completing the cutting of the material. In the laser cutting process, intelligent conveyor lines are usually used to transport the workpiece, thereby achieving continuous cutting operations.

[0003] Prior art 1 (Chinese patent with announcement number CN109665162B and announcement date of 2024-04-09) discloses a laser cutting conveyor line for plastic sealant, comprising: a shaping conveyor mechanism, wherein the output end of the shaping conveyor mechanism is provided with a product arranging device, and the shaping conveyor mechanism is used to convey products with excess plastic sealant to be removed to the product arranging device; a cutting conveyor mechanism, wherein the cutting conveyor mechanism is provided with a plurality of product positioning molds along its conveying direction, and the cutting conveyor mechanism is used to convey the product positioning molds to pass sequentially through a laser cutting mechanism and a dust removal mechanism; a loading robot, wherein the loading robot is used to grab products in the product arranging device and place them onto the product positioning molds; a pallet loading conveyor mechanism, wherein the pallet loading conveyor mechanism is used to convey pallets; and an unloading robot, wherein the unloading robot is used to grab products from the output end of the cutting conveyor mechanism and place them into the pallet.

[0004] There is also prior art 2 (Chinese patent with announcement number CN208450844U and announcement date of 2019-02-01) for a conveyor line for an automated production line for laser cutting metal sheets, which includes a frame, a tray, an upper conveyor line and a lower conveyor line arranged in two layers along the length of the frame, an upper drive motor and a lower drive motor respectively for driving the upper conveyor line and the lower conveyor line to rotate, and a baffle assembly spaced apart on the upper conveyor line to limit the tray of the conveyor line. The trays are placed flat on the upper and lower conveyor lines and move. The baffle assembly includes a drive cylinder vertically fixed on the frame and a baffle fixedly installed on the top of the piston rod of the drive cylinder to control the tray to stop moving forward and shake. It can smoothly and accurately convey the cut small metal sheets on the conveyor line with high efficiency. At the same time, its structure is simple and easy to install and operate.

[0005] However, in actual use, the surface temperature of the workpiece is high after the cutting and welding are completed, which makes it easy for the workpiece to stick to the conveyor structure during the conveying process. This can lead to workpiece jamming and affect the normal progress of subsequent processing operations. At the same time, most existing conveyor lines do not have an automatic anti-sticking and jamming structure, which requires manual assistance and greatly increases the labor intensity of the workers. In order to address the above problems, there is an urgent need to innovate the design based on the existing intelligent conveyor lines for laser cutting.

[0006] Therefore, we propose an intelligent conveyor line for laser cutting to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide an intelligent conveyor line for laser cutting, in order to solve the problem mentioned in the background art that, in actual use, after the workpiece is cut and welded, its surface temperature is high, and it is easy for it to stick to the conveyor structure during the conveying process, which leads to workpiece conveying jamming and affects the normal progress of subsequent processing operations. At the same time, most existing conveyor lines do not have an automatic anti-sticking and jamming structure, which requires manual assistance and greatly increases the labor intensity of workers.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an intelligent conveyor line for laser cutting, comprising a laser cutting table, a first conveying component for conveying the workpiece to be cut is provided on the left side of the laser cutting table, and an auxiliary conveying component for assisting in the conveying of the material is provided directly below the laser cutting table. The auxiliary conveying component has a support frame inside, and a striking mechanism is provided between the support frames. The striking mechanism performs front-to-back and up-and-down striking operations on the support frames by the lateral movement of the sliding block contained therein. The workpiece may jam during conveying or stick to the auxiliary conveying component after welding.

[0009] Preferably, the support frame is fixedly connected inside the auxiliary conveying assembly, and the support frames are evenly distributed to provide auxiliary support for the workpiece and prevent the workpiece from directly contacting the laser cutting table.

[0010] Preferably, the striking mechanism includes a sliding groove, which is formed inside the two sets of support frames in the middle, and a sliding block is slidably connected inside the sliding groove, and a return spring is fixedly connected between the side of the sliding block and the support frame.

[0011] Preferably, a rubber pad is fixedly connected to the upper surface of the sliding block, and the rubber pad is in contact with the lower surface of the workpiece. The friction between the workpiece and the rubber pad drives the sliding block to move laterally along the slide groove.

[0012] Preferably, a limiting rod is fixedly connected inside the laser cutting stage, and a sliding plate is slidably connected to the outside of the limiting rod. A first spring is fixedly connected between the upper surface of the sliding plate and the upper end of the limiting rod.

[0013] Preferably, the sliding plate is arranged in an "I" shape when viewed from above, and striking blocks are fixedly connected to the upper surfaces of both sides of the sliding plate. The striking blocks are located below the support frame, and the positions of the striking blocks and the support frame are one-to-one. The up and down movement of the sliding plate drives the striking blocks to strike the support frame, causing the support frame to vibrate, thus preventing the workpiece from getting stuck or sticking on the surface of the auxiliary conveying component.

[0014] Preferably, a zigzag plate is fixedly connected to the upper surface of the sliding plate, and an abutment plate is fixedly connected to the lower surface of the sliding block. The lower ends of the abutment plate are arranged in an arc shape on both sides, and the lower surface of the abutment plate abuts against the upper surface of the zigzag plate.

[0015] Preferably, the striking mechanism includes a rotating shaft, which is rotatably connected inside the laser cutting table. The rotating shaft is distributed on the side of the sliding plate, and a striking plate is fixedly connected to the upper side of the rotating shaft. The striking plate is in contact with the side of the support frame when tilted.

[0016] Preferably, a fixed magnetic block is fixedly connected to the lower side of one edge of the zigzag plate, and a driving magnetic plate is fixedly connected to the lower outer side of the rotating shaft. When the zigzag plate moves down to the lowest point, the fixed magnetic block and the driving magnetic plate are positioned correspondingly. A torsion spring is fixedly connected between the lower side of the driving magnetic plate and the laser cutting table, and the torsion spring is wound around the outer side of the rotating shaft.

[0017] Compared with the prior art, the beneficial effects of this invention are: This intelligent conveyor line for laser cutting can utilize the friction between the workpiece and the rubber pad during the conveying process to drive the sliding block to move. Combined with the contact action of the abutment plate and the zigzag plate, it automatically drives the sliding plate downwards, causing the striking block on the sliding plate to strike the support frame up and down. Simultaneously, when the sliding plate reaches its lowest point, the magnetic attraction between the fixed magnetic block and the driving magnetic plate drives the rotating shaft to rotate, causing the striking plate to strike the support frame laterally, resulting in continuous vibration of the support frame. This eliminates the need for additional manual operation and effectively prevents the workpiece from sticking to the auxiliary conveying components after high-temperature processing, preventing workpiece jamming during conveying, ensuring smooth cutting operations, and reducing the labor intensity of workers. Equipped with a support frame, the workpiece is further supported, reducing the contact area between the workpiece and the laser cutting table and lowering the probability of cutting residue sticking. In conjunction with the lateral movement of the sliding block driven by the friction of the workpiece, the striking block strikes the bottom of the support frame and the striking plate strikes the sides of the support frame, causing the support frame to vibrate regularly. This automatically dislodges stuck workpieces during the conveying process and shakes off cutting residue stuck to the support frame, eliminating the need for manual cleaning and ensuring stable and continuous operation of the conveyor line.

[0018] The sliding block is moved by the friction between the workpiece and the rubber pad during the conveying process. The knocking mechanism can be operated without the need for an additional power component, which is more energy-saving and environmentally friendly and reduces the overall energy consumption of the device. During the movement of the sliding block, the contact plate will squeeze and push the curved plate to move down, and then drive the knocking block to move down synchronously through the sliding plate. After the sliding block moves to the end of the stroke and the workpiece stops moving, the return spring will drive the sliding block to return to its original position. The first spring will also drive the sliding plate and the knocking block to return to their original position. The knocking block will hit the support frame upward, causing the support frame to vibrate as a whole, thereby loosening the stuck workpiece and shaking off the stuck workpiece. When the zigzag plate moves down to its lowest point, the fixed magnetic block will be opposite the driving magnetic plate. The repulsive force between the same magnetic poles will drive the rotating shaft and the striking plate to rotate, causing the striking plate to quickly strike the side of the support frame. After the fixed magnetic block moves up and resets with the zigzag plate, the torsion spring will drive the rotating shaft and the striking plate to reset, realizing the front and rear sides of the support frame being struck. Combined with the vibration generated by the up and down striking of the striking block, it can effectively prevent the workpiece from getting stuck during the conveying process. It can also shake off and clean the waste material that is stuck to the auxiliary conveying components after processing, ensuring the stability of the device's conveying. No manual cleaning is required, reducing the intensity of manual labor. Attached Figure Description

[0021] 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.

[0022] Example 1: As Figure 1 - Figure 3 The present invention provides the following technical solution: an intelligent conveyor line for laser cutting, wherein a first conveying component 2 for conveying the workpiece to be cut is provided on the left side of the laser cutting table 1, and an auxiliary conveying component 3 for assisting in the conveying of the material is provided directly below the laser cutting table 1, and a support frame 4 is fixedly connected inside the auxiliary conveying component 3, and the support frames 4 are evenly distributed to assist in the support of the workpiece, thereby preventing the workpiece from directly contacting the laser cutting table 1.

[0023] The workpiece to be cut is transported to the auxiliary conveying component 3 on the laser cutting table 1 by the first conveying component 2. The upper surface of the auxiliary conveying component 3 is provided with a support frame 4, which supports the workpiece in the air, reducing the contact area between the workpiece and the inner wall of the laser cutting table 1, and reducing the probability of residue sticking to the inside of the device after cutting.

[0024] Example 2: To prevent workpieces from jamming during transport, a striking mechanism is provided. This mechanism strikes the support frame 4 from multiple directions, causing the support frame 4 to vibrate synchronously with the workpiece, thus loosening jammed workpieces and shaking off sticky residue. Figure 4 - Figure 7The present invention provides the following technical solution: an intelligent conveyor line for laser cutting, wherein an auxiliary conveyor assembly 3 is provided with a support frame 4 inside, and a striking mechanism is provided between the support frames 4. The striking mechanism performs front-to-back and up-and-down striking operations on the support frame 4 by the lateral movement of the sliding block 6 included therein. This addresses situations where the workpiece gets stuck during conveying or sticks to the auxiliary conveyor assembly 3 after welding. The striking mechanism includes a slide groove 7, which is opened inside the two sets of support frames 4 in the middle. A sliding block 6 is slidably connected inside the slide groove 7, and a return spring 8 is fixedly connected between the side of the sliding block 6 and the support frame 4. A rubber pad 5 is fixedly connected to the upper surface of the sliding block 6, and the rubber pad 5 contacts the lower surface of the workpiece. The friction between the workpiece and the rubber pad 5 drives the sliding block 6 to move laterally along the slide groove 7. The laser cutting table 1 is located inside... A limiting rod 13 is fixedly connected, and a sliding plate 12 is slidably connected to the outside of the limiting rod 13. A first spring 14 is fixedly connected between the upper surface of the sliding plate 12 and the upper end of the limiting rod 13. The sliding plate 12 is arranged in an "I" shape when viewed from above. A striking block 15 is fixedly connected to the upper surfaces of both sides of the sliding plate 12. The striking block 15 is located below the support frame 4, and the striking block 15 corresponds to the position of the support frame 4. The up and down movement of the sliding plate 12 drives the striking block 15 to strike the support frame 4, causing the support frame 4 to vibrate, thus preventing the workpiece from getting stuck or sticking on the surface of the auxiliary conveying component 3. A zigzag plate 10 is fixedly connected to the upper surface of the sliding plate 12, and an abutment plate 11 is fixedly connected to the lower surface of the sliding block 6. The lower ends of the abutment plate 11 are arranged in an arc shape, and the lower surface of the abutment plate 11 abuts against the upper surface of the zigzag plate 10.

[0025] The workpiece is placed above the support frame 4 of the auxiliary conveying assembly 3. The lower surface of the workpiece contacts the rubber pad 5 on the upper surface of the sliding block 6. As the workpiece moves along the conveying direction, the friction between the workpiece and the rubber pad 5 will cause the sliding block 6 to move laterally along the slide groove 7, while simultaneously compressing the return spring 8 on the side of the slide groove 7. During the movement of the sliding block 6, the contact plate 11 fixedly connected below it will move synchronously. When the contact plate 11 moves to the protruding part of the curved plate 10, the lower end of the contact plate 11 will press against the upper surface of the curved plate 10, pushing the curved plate 10 to drive the sliding plate 12 to slide downward along the limit rod 13, while simultaneously stretching the first spring above the sliding plate 12. When the contact plate 11 moves to the recessed part of the curved plate 10, the first spring 14 will pull the sliding plate 12 and the striking block 15 upward, so that the striking block 15 will strike the bottom of the support frame 4 simultaneously, causing the support frame 4 to vibrate up and down, so that the workpiece will be slightly misaligned and loosened with the support frame 4 during transportation, avoiding the workpiece from getting stuck or sticking during transportation. When the workpiece leaves the current position after cutting, the reset spring 8 will push the sliding block 6 to reset. During this process, the sliding block 6 will move in the opposite direction, and the contact plate 11 will squeeze the curved plate 10 again, causing the striking block 15 to strike the support frame 4 multiple times again, further improving the effect of vibration cleaning.

[0026] Example 3: Based on Example 2, by lowering the flexural plate 10, the striking plate 19 strikes the side of the support frame 4, causing the support frame 4 to vibrate in the front-to-back direction, forming multi-directional vibration, further improving the loosening effect on stuck workpieces and the cleaning effect on sticky residue, such as... Figure 7 - Figure 9 The present invention provides the following technical solution: an intelligent conveyor line for laser cutting, the striking mechanism including a rotating shaft 16, the rotating shaft 16 being rotatably connected inside the laser cutting table 1, and the rotating shaft 16 being distributed on the side of the sliding plate 12, and a striking plate 19 being fixedly connected to the upper side of the rotating shaft 16, while the striking plate 19 is in contact with the side of the support frame 4 in an inclined state, a fixed magnetic block 9 being fixedly connected to the lower side of one side of the curved plate 10, a driving magnetic plate 18 being fixedly connected to the lower outer side of the rotating shaft 16, and when the curved plate 10 moves down to the lowest point, the fixed magnetic block 9 and the driving magnetic plate 18 are positioned correspondingly, a torsion spring 17 being fixedly connected between the lower side of the driving magnetic plate 18 and the laser cutting table 1, and the torsion spring 17 being wound around the outer side of the rotating shaft 16.

[0027] When the zigzag plate 10 moves the fixed magnetic block 9 to its lowest point, the fixed magnetic block 9 will move to the corresponding position of the driving magnetic plate 18. The fixed magnetic block 9 and the driving magnetic plate 18 have the same magnetic poles on their adjacent sides. The same magnetic poles repel each other, and the repulsive force will push the driving magnetic plate 18 to drive the rotating shaft 16 to rotate. At the same time, the torsion spring 17 is twisted. When the rotating shaft 16 rotates, it will drive the upper striking plate 19 to swing rapidly. The striking plate 19 will directly strike the side of the support frame 4, causing the support frame 4 to vibrate in the front and back directions. When the zigzag plate 10 moves the fixed magnetic block 9 to its lowest point, the fixed magnetic block 9 will move to the corresponding position of the driving magnetic plate 18. After the fixed magnetic block 9 moves upward and resets, it moves away from the driving magnetic plate 18, and the repulsive force disappears. The torsion spring 17 will drive the rotating shaft 16 and the striking plate 19 to rotate in the opposite direction and reset. During the reset process, the striking plate 19 will touch the side of the support frame 4 again to achieve a secondary strike. Together with the striking block 15, it strikes the bottom of the support frame 4 from top to bottom, forming a multi-directional composite vibration, which effectively avoids workpiece jamming and shakes off the residue stuck on the support frame 4. There is no need for manual shutdown for cleaning, ensuring the continuous and stable operation of the conveyor line.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
