Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and in particular to a laser cutting apparatus with dual-layer replacement loading and unloading. Background Technology

[0002] Laser cutting is a technology that uses a high-energy-density laser beam to cut various materials. A high-energy beam generated by a laser is focused onto an extremely small point, forming a high-temperature, high-energy-density spot that instantly melts or vaporizes the material locally. The melted or vaporized material is then blown away by an airflow, thus achieving the cutting process. Laser cutting offers advantages such as high precision, fast processing speed, and minimal heat-affected zone, making it suitable for cutting metals, non-metals, and various composite materials. In the industrial sector, laser cutting is widely used in automotive manufacturing, aerospace, and electronic equipment manufacturing, becoming an important materials processing technology.

[0003] The current laser cutting equipment has the following problems with loading and unloading: The loading and unloading of the cutting blades and the cut materials are not separated. The raw materials are simply loaded and the whole material is unloaded. Manual material separation is still required, resulting in high labor costs and low automation. During the loading and unloading process, both loading and unloading require initial manual assistance to facilitate the material entering the lower end of the laser cutting head. However, the cutting discs for large-scale cutting are very large and heavy, which makes the operation cumbersome and the work efficiency low.

[0004] Therefore, an automated laser cutting device with dual-layer replacement loading and unloading is needed. Summary of the Invention

[0005] In order to solve all or part of the above problems, the present invention aims to provide a laser cutting device with dual-layer replacement loading and unloading, so as to ensure automatic loading of materials throughout the process, and to automatically sort raw materials, cut products and waste materials, thereby improving work efficiency and reducing labor costs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a laser cutting device with double-layer replacement loading and unloading, comprising a laser cutting host and a floating support component installed in the inner cavity of the laser cutting host. A support conveying component is also installed in the inner cavity of the laser cutting host, and the upper end of the support conveying component can penetrate the floating support component. Layering components are installed inside the laser cutting host at both ends of the floating support component, and the upper end of the layering components can also penetrate the floating support component. A horizontal conveyor is provided on one side of the laser cutting host, a loading tilting machine is placed on one side of the horizontal conveyor, and a unloading tilting machine is placed on the other side of the horizontal conveyor. A pushing component is provided on one side of the horizontal conveyor opposite to the laser cutting host. A controller is also installed on the horizontal conveyor. The laser cutting host, the floating support component, the loading tilting machine, the horizontal conveyor, the unloading tilting machine, and the pushing component are all controlled by the controller.

[0007] Furthermore, the floating support component includes a telescopic column and a welding plate installed on the upper end of the telescopic column. The upper end of the welding plate is provided with multiple serrated grooves for supporting the piece to be cut. Transmission plates are provided on the lower sides of both ends of the welding plate, and the transmission plates correspond to the layered components.

[0008] Furthermore, the supporting conveying component includes a transmission component and a servo motor disposed at the lower end of one side of the transmission component. Multiple sets of conveying components are disposed at the upper end of the transmission component. The transmission component and the conveying components are connected by an meshing connection. The servo motor can drive the transmission component to rotate, and the rotation of the transmission component can drive the multiple sets of conveying components to rotate. The driving end of the conveying component can penetrate the welding plate.

[0009] Furthermore, the layered component includes a lower support plate and extension rods installed at both ends of the lower support plate. The upper end of the extension rod is provided with a support roller, and the lower end of the lower support plate is provided with multiple elastic elements. The transmission plate corresponds to the lower support plate.

[0010] Furthermore, the conveying component includes a lower drive gear and a drive gear belt that is sleeved on the outside of the lower drive gear. An upper drive gear is provided at the end of the drive gear belt away from the lower drive gear. A drive roller is provided on the upper drive gear. Fine teeth are provided on the outside of the drive roller. The diameter of the drive roller matches the through groove opened in the welding plate.

[0011] Furthermore, the transmission plate includes a connecting plate and a magnetic plate movably disposed inside the lower end of the connecting plate. An upper magnetic block is installed inside the lower end of the connecting plate located at the upper end of the magnetic plate. The upper magnetic block is magnetically attracted to the magnetic plate. A lower magnetic block is embedded in the upper end of the lower support plate. The magnetic plate is magnetically attracted to the lower magnetic block. The magnetic attraction force of the lower magnetic block is greater than that of the upper magnetic block.

[0012] Furthermore, the pushing component includes a telescopic rod and a push plate installed at the drive end of the telescopic rod. Multiple sensors are embedded in the side of the push plate away from the telescopic rod. The sensors are electrically connected to the controller and are used to identify the piece to be cut, the scrap, and the product.

[0013] Furthermore, the laser cutting host includes a transverse moving support platform and a longitudinal moving support platform installed on the upper end of the transverse moving support platform. A laser cutting head is installed on the upper end of the longitudinal moving support platform. Through the cooperation of the transverse moving support platform and the longitudinal moving support platform, the laser cutting head can be driven to cut the sheet to be cut arbitrarily.

[0014] Another method for implementing a laser cutting apparatus is provided, comprising the following steps: S1: The piece to be cut is placed on the feeding tilting machine and transported to the middle of the horizontal conveyor. The sensor identifies the piece to be cut, and the telescopic rod drives the piece to be cut to the upper end of the supporting conveyor component. S2: At this time, the telescopic column is activated to move the welding plate upward until the upper surface of the welding plate is on the same horizontal line as the upper surface of the support roller. At this time, the cutting disc is supported and laser cutting can be performed. S3: After cutting is completed, the telescopic column initially moves down until it is level with the upper surface of the support roller and the transmission plate contacts the lower support plate. During this process, the support roller moves upward relative to the support roller. Since the position of the piece to be cut is set in advance, the support roller will not be cut. At this time, the uncut material is supported by the support roller, and the cut product falls to the upper surface of the conveyor under its own weight. Then, the servo motor is started to drive multiple conveyors to transport the product to the horizontal conveyor. The horizontal conveyor is then started to transport the product from the unloading tilting machine. S4: After the material is unloaded, continue to control the telescopic column to move down. At this time, the transmission plate pushes the lower support plate to move down until the conveying component is level with the support roller. At this time, the remaining material can be conveyed to the horizontal conveyor. Then start the horizontal conveyor to convey the product from the unloading tilting machine.

[0015] Furthermore, in step S3, as the transmission plate moves downward, the magnetic attraction force of the lower magnetic block is greater than that of the upper magnetic block, and the distance between the magnetic plate and the lower magnetic block becomes smaller and smaller. Finally, before the two come into contact, the lower magnetic block quickly attracts the magnetic plate. During the attraction process, the magnetic plate moves downward quickly and impacts the lower magnetic block. At this time, the lower support plate is impacted, and with the cooperation of the elastic element, the lower support plate shakes, which in turn drives the support roller to shake, causing the upper residual material to shake, making the product stuck on the residual material easy to fall off.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The laser cutting device proposed in this invention features a dual-layer, interchangeable loading and unloading system. The blank to be cut is placed on a tilting loading machine and transported to the middle of a horizontal conveyor. At this point, a pushing component senses and pushes the blank to the upper end of a supporting conveyor. Simultaneously, the supporting conveyor transports the blank to a designated position below the laser cutting host. Then, a floating support component moves upward to lift the blank, allowing the laser cutting host to perform the cutting. After cutting, the floating support component initially moves downward. At this time, a layering component prioritizes lifting the remaining material. The product falls onto the upper surface of the supporting conveyor under gravity, forming layers. Then, the supporting conveyor reverses direction to return the product to the upper surface of the supporting conveyor. The material is conveyed to a horizontal conveyor, which then transports the product from the unloading tilting machine. The floating support component is then moved downwards, causing the layering component to move downwards until its upper surface is level with the support conveyor component. The remaining material is then transported back to the horizontal conveyor, which is then activated again to transport the product from the unloading tilting machine. This process is repeated, allowing for automated feeding, sorting, and unloading of large pieces to be cut. The remaining material and the finished product can be separated, improving the overall automation level and work efficiency, while also reducing the hassle of manual feeding and sorting, thus lowering labor costs.

[0019] 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.

[0020] like Figures 1-4As shown, a laser cutting device with double-layer replacement loading and unloading includes a laser cutting host 1 and a floating support component 2 installed in the inner cavity of the laser cutting host 1. A support conveying component 3 is also installed in the inner cavity of the laser cutting host 1. The upper end of the support conveying component 3 can penetrate the floating support component 2. Layering components 4 are installed inside the laser cutting host 1 at both ends of the floating support component 2. The upper end of the layering components 4 can also penetrate the floating support component 2. A horizontal conveyor 7 is provided on one side of the laser cutting host 1. A loading tilting machine 6 is placed on one side of the horizontal conveyor 7. A unloading tilting machine 8 is placed on the other side of the horizontal conveyor 7. A pushing component 9 is provided on one side of the horizontal conveyor 7 opposite to the laser cutting host 1. A controller 10 is also installed on the horizontal conveyor 7. The laser cutting host 1, the floating support component 2, the loading tilting machine 6, the horizontal conveyor 7, the unloading tilting machine 8, and the pushing component 9 are all controlled by the controller 10.

[0021] Specifically, the blank 5 to be cut is placed on the feeding tilting machine 6 and conveyed to the middle of the horizontal conveyor 7. At this time, the pushing component 9 senses and pushes the blank 5 to the upper end of the supporting conveying component 3. The supporting conveying component 3 simultaneously conveys the blank 5 to the designated position below the laser cutting host 1. Then, the floating support component 2 moves upward to lift the blank 5, and the laser cutting host 1 performs cutting. After cutting, the floating support component 2 moves downward initially. At this time, the layering component 4 prioritizes lifting the remaining material 51. The product 52 falls onto the upper surface of the supporting conveying component 3 under the action of gravity, forming layers. Then, the supporting conveying component 3 reverses and conveys the product 52 to the horizontal conveyor. 7. Then, the horizontal conveyor 7 is started again to transport the product 52 from the unloading tilting machine 8. Then, the floating support component 2 is controlled to move down again, which will drive the layering component 4 to move down until the upper surface of the layering component 4 is on the same horizontal line as the upper surface of the support conveying component 3. Then, the remaining material 51 is transported to the horizontal conveyor 7, and the horizontal conveyor 7 is started again to transport the product 52 from the unloading tilting machine 8. This process is repeated to automatically load, divide, and unload large pieces of material to be cut 5. The remaining material 51 and the product 52 can be separated, which not only improves the automation level of the entire equipment and increases work efficiency, but also reduces the trouble of manual loading and dividing, thus reducing labor costs.

[0022] like Figure 3 As shown, the laser cutting host 1 includes a transverse moving support platform 11 and a longitudinal moving support platform 12 installed on the upper end of the transverse moving support platform 11. A laser cutting head 13 is installed on the upper end of the longitudinal moving support platform 12. Through the cooperation of the transverse moving support platform 11 and the longitudinal moving support platform 12, the laser cutting head 13 can be driven to cut the sheet 5 arbitrarily, ensuring the flexibility of cutting.

[0023] like Figure 1As shown, the pushing component 9 includes a telescopic rod 91 and a push plate 92 installed on the drive end of the telescopic rod 91. Multiple sensors 93 are embedded in the side of the push plate 92 away from the telescopic rod 91. The sensors 93 are electrically connected to the controller 10 and are used to identify the piece to be cut 5, the scrap 51, and the product 52. When the piece to be cut 5, the scrap 51, and the product 52 arrive at the horizontal conveyor 7 in sequence, the telescopic rod 91 is activated to push the push plate 92 to push the piece to be cut 5 onto the supporting conveying component 3. When the product 52 or the scrap 51 is identified, it is conveyed and discharged by the horizontal conveyor 7. The degree of intelligent automation is high, and the work efficiency is improved.

[0024] like Figures 4-7 and Figure 9 As shown, the floating support component 2 includes a telescopic column 21 and a welding plate 22 installed on the upper end of the telescopic column 21. The upper end of the welding plate 22 is provided with multiple serrated grooves for supporting the piece to be cut 5. The lower sides of both ends of the welding plate 22 are provided with transmission plates 23, which correspond to the layered component 4. The supporting conveying component 3 includes a transmission component 31 and a servo motor 32 located at the lower end of one side of the transmission component 31. The transmission component 31 is composed of a protective plate, a guide column and a long gear belt. Multiple sets of conveying components 33 are provided at the upper end of the transmission component 31. The transmission component 31 and the conveying components 33 are connected by meshing. The servo motor 32 can drive the transmission component 31 to rotate. The rotation of the transmission component 31 can drive the multiple sets of conveying components 33 to rotate. The driving end of the conveying component 33 can penetrate the welding plate 22. The layered component 4 includes a lower support plate 41 and extension rods 42 installed at both ends of the lower support plate 41. The upper end of the extension rods 42 is provided with support rollers 43, and the lower end of the lower support plate 41 is provided with multiple elastic elements 44. The transmission plate 23 corresponds to the lower support plate 41.

[0025] Specifically, when the cutting disc 5 is initially conveyed onto the supporting conveying component 3, the upper surface of the welding plate 22 is lower than the upper surface of the conveying component 33, while the upper surface of the supporting roller 43 is on the same horizontal line as the upper surface of the conveying component 33. At this time, the telescopic column 21 is activated to drive the welding plate 22 to move upward until the upper surface of the welding plate 22 is on the same horizontal line as the upper surface of the supporting roller 43. At this time, the cutting disc 5 is supported and laser cutting can be performed. After cutting is completed, the telescopic column 21 initially moves downward until it is level with the upper surface of the supporting roller 43 and the transmission plate 23 contacts the lower support plate 41. During the process, the supporting roller 43 moves upward relative to the cutting disc 5. Since the position of the supporting roller 43 corresponding to the cutting disc 5 is set in advance, The cutting process is complete. At this point, the uncut scrap 51 is supported by the support roller 43, while the cut product 52 falls onto the upper surface of the conveyor 33 under its own weight. Then, the servo motor 32 is started, which drives multiple conveyors 33 to transport and unload the product 52. After unloading, the telescopic column 21 is controlled to move downward. At this time, the transmission plate 23 pushes the lower support plate 41 downward until the conveyor 33 is level with the support roller 43. At this time, the scrap 51 can be transported, thus completing the unloading of the scrap 51. The floating support component 2, the support conveyor component 3, and the layering component 4 return to their initial state, which is convenient for the next operation. The structure is simple and the operation is convenient. It realizes automated feeding, sorting, and unloading, thereby improving work efficiency.

[0026] like Figure 10 As shown, the conveyor 33 includes a lower drive gear 331 and a drive gear belt 332 that is sleeved on the outside of the lower drive gear 331. An upper drive gear 333 is provided at the end of the drive gear belt 332 away from the lower drive gear 331. A drive roller 34 is provided on the upper drive gear 333. Fine teeth are provided on the outer side of the drive roller 34. The diameter of the drive roller 34 matches the through groove 221 opened in the welding plate 22. During the process of the welding plate 22 moving up and down, the drive roller 34 is always driven to rotate by the lower drive gear 331. The residue that splashes onto the through groove 221 during the cutting process is cut and cleaned by the rotating fine teeth, ensuring that the welding plate 22 is clean. The welding plate 22 is cleaned by the loading and unloading operation in a clever way. The cleaning method is simple and practical. It also solves the problem of troublesome surface cleaning of the welding plate 22 after long-term use and improves the flexibility of the entire equipment.

[0027] The supporting conveying component 3 also includes a triangular support plate 35 and a fixing column 36 for connecting the opposing triangular support plates 35. The upper end of the triangular support plate 35 is provided with a plurality of support blocks 37. The upper end of the support block 37 is connected to the end of the transmission roller 34 to support the transmission roller 34 and ensure that the transmission roller 34 can rotate.

[0028] like Figure 8As shown, the transmission plate 23 includes a connecting plate 231 and a magnetic plate 232 movably disposed inside the lower end of the connecting plate 231. An upper magnetic block 233 is installed inside the lower end of the connecting plate 231 located above the magnetic plate 232. The upper magnetic block 233 is magnetically attracted to the magnetic plate 232. A lower magnetic block 411 is embedded in the upper end of the lower support plate 41. The magnetic plate 232 is magnetically attracted to the lower magnetic block 411. The magnetic attraction force of the lower magnetic block 411 is greater than that of the upper magnetic block 233. During the downward movement of the transmission plate 23, because the magnetic attraction force of the lower magnetic block 231 is greater than that of the upper magnetic block 232, the magnetic attraction force of the lower magnetic block 232 is greater than that of the upper magnetic block 233. With magnetic attraction force 33, the distance between the magnetic plate 232 and the lower magnetic block 411 becomes smaller and smaller. Finally, before they come into contact, the lower magnetic block 411 quickly attracts the magnetic plate 232. During the attraction process, the magnetic plate 232 moves down quickly and impacts the lower magnetic block 411. At this time, the lower support plate 41 is impacted. With the cooperation of the elastic element 44, the lower support plate 41 shakes, which in turn drives the support roller 43 to shake, causing the upper residual material 51 to shake. This makes it easier for the product 52 stuck on the residual material 51 to fall off, ensuring the accuracy of the unloading, improving the smoothness and accuracy of the entire laser cutting unloading process, and improving work efficiency.

The multiple conveyor components (33) are driven to transport the product (52) to the horizontal conveyor (7), and then the horizontal conveyor (7) is started to transport the product (52) from the unloading tilting machine (8); S4: After the unloading is completed, the telescopic column (21) is controlled to move down. At this time, the transmission plate (23) pushes the lower support plate (41) to move down until the conveyor component (33) is level with the support roller (43). At this time, the remaining material (51) is transported to the horizontal conveyor (7), and then the horizontal conveyor (7) is started to transport the product (52) from the unloading tilting machine (8).

7. A method for implementing the laser cutting apparatus as described in claim 6, characterized in that, In step S3, as the transmission plate (23) moves downward, the magnetic attraction force of the lower magnetic block (411) is greater than that of the upper magnetic block (233), and the distance between the magnetic plate (232) and the lower magnetic block (411) becomes smaller and smaller. Finally, before the two come into contact, the lower magnetic block (411) quickly attracts the magnetic plate (232). During the attraction process, the magnetic plate (232) moves downward quickly and impacts the lower magnetic block (411). At this time, the lower support plate (41) is impacted. With the cooperation of the elastic element (44), the lower support plate (41) shakes and drives the support roller (43) to shake, causing the upper residual material (51) to shake, making the product (52) stuck on the residual material (51) easy to fall off.
