Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, specifically to a multi-station integrated laser cutting machine. Background Technology

[0002] A laser cutting machine is an intelligent device that uses a high-energy laser beam as a cutting tool. Through laser irradiation, it can precisely cut and engrave various materials such as metal and acrylic. This technology is known for its high precision, high speed and flexibility, and is widely used in industrial manufacturing and advertising processing. In order to further improve processing efficiency, laser cutting machines have realized multi-station processing.

[0003] Laser cutting machines used for metal cutting typically have multiple serrated grids on top. When laser cutting metal sheets, the sheet is placed on top of the grids for cutting. After the cutting is completed, smaller finished products and scrap fall into the machine through the gaps between the grids, while larger finished products remain on top of the grids. Larger finished products and scrap are usually heavier, and removing them from the middle of the grids by direct handling can be difficult due to their weight and distance. Pulling the finished product directly can cause its bottom to rub against the grid, resulting in scratches and affecting the quality of the finished product. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-station integrated laser cutting machine to solve the problems mentioned in the background art.

A second lifting frame (second type) is disposed above each of the first lifting frames. A plurality of uniformly distributed fixed bases are fixedly installed inside each of the first lifting frames. A mounting frame is disposed above each of the fixed bases. A conveyor wheel is rotatably installed inside each of the mounting frames. A plurality of uniformly distributed H-shaped connecting frames are fixedly installed inside each of the second lifting frames. A plurality of uniformly distributed ejector pins are fixedly installed on the top of each of the second lifting frames and the H-shaped connecting frames. A first lifting mechanism, a second lifting mechanism, and a turning mechanism are disposed inside the frame.

[0006] Preferably, the first lifting mechanism includes a lifting frame and two cylinders. The two cylinders are symmetrically fixedly installed inside the frame. The telescopic shaft ends of the two cylinders are respectively fixedly connected to both ends of the lifting frame. Both ends of the lifting frame are slidably installed on multiple evenly distributed guide rods. The multiple guide rods are all fixedly installed inside the frame. Connecting rods are fixedly installed at both ends of the bottom of the multiple lifting frames. The bottoms of the multiple connecting rods are fixedly connected to the lifting frame. Sub-rods are fixedly installed at both ends of the bottom of the lifting frame.

[0007] Preferably, the second lifting mechanism includes a lifting frame and two cylinders. The two cylinders are fixedly installed at both ends of the top of two auxiliary rods. The two ends of the lifting frame are fixedly installed inside. The telescopic shaft ends of the two cylinders are fixedly connected to the two auxiliary rods. Multiple evenly distributed connecting rods are fixedly installed at both ends of the top of the lifting frame. The tops of the multiple connecting rods are fixedly connected to their respective H-shaped connecting frames. Sliding sleeves are slidably sleeved on the outside of the multiple connecting rods. The ends of the multiple sliding sleeves away from their respective connecting rods are fixedly connected to the corresponding connecting rods.

[0008] Preferably, multiple evenly distributed guide rods are fixedly installed at both ends of the top of the multiple lifting frames, and the multiple guide rods are slidably connected to their respective corresponding lifting frames.

[0009] Preferably, the steering mechanism includes a threaded rod and a transmission assembly. The threaded rod is threadedly connected to one end of the frame. An adjusting plate is rotatably mounted on one end of the threaded rod. Guide rods are slidably sleeved inside both ends of the adjusting plate. Both guide rods are fixedly connected to the inner wall of the frame. Sliding grooves are opened at both ends of the adjusting plate. L-shaped adjusting rods are slidably sleeved inside both sliding grooves. Two annular limiting plates are fixedly mounted on the outside of the two L-shaped adjusting rods near the end of the adjusting plate. The four annular limiting plates are respectively arranged on both sides of the adjusting plate. The transmission assembly is arranged below the multiple lifting frames.

[0010] Preferably, the transmission assembly includes an adjusting frame, with its top two ends slidably connected to their respective supporting frames, one side of which is fixedly connected to two L-shaped adjusting rods. Multiple evenly distributed crossbars are fixedly installed inside the adjusting frame. Multiple evenly distributed rotating shafts are fixedly installed on the top of the adjusting frame and the tops of the multiple crossbars. Sliding sleeves are rotatably installed on the tops of the multiple rotating shafts. L-shaped rotating rods are slidably fitted inside the multiple sliding sleeves.

Multiple conveyor wheels lift large finished products and waste materials, allowing workers to pull them. With the help of multiple conveyor wheels, not only is it labor-saving, but friction is also reduced, making it suitable for metal products with low precision requirements and improving the cutting effect of the laser cutting machine.

[0014] By using the second lifting frame and the ejector pin, the second lifting mechanism raises both the second lifting frame and the ejector pin, making the height of the ejector pin higher than the height of the conveyor wheel. Then, under the action of the first lifting mechanism, it is raised, and the ejector pin is used to lift large finished products and waste materials, so that the bottom of the finished product is separated from multiple rough grids. The workers then use suction cups and other tools to remove the finished product, avoiding damage to the bottom of the finished product caused by sliding friction, which would affect the quality of metal finished products with high precision requirements. This method is suitable for metal finished products with high precision requirements.

[0015] By using a steering mechanism to rotate the threaded rod, the transmission components can be activated to simultaneously adjust the orientation of multiple conveyor wheels. This allows for adjustment of the orientation when pulling large finished products and waste materials, meeting the different needs of staff. Attached Figure Description

[0018] 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.

[0019] This invention provides a technical solution: such as Figure 1 - Figure 11The multi-station integrated laser cutting machine shown includes a frame 1 and multiple evenly distributed laser cutting devices 2 disposed on the top of the frame 1. Multiple evenly distributed grids 3 are fixedly installed on the top of the frame 1. Multiple evenly distributed lifting frames 4 are disposed inside the frame 1. Each of the lifting frames 4 has a second lifting frame 8 above it. Multiple evenly distributed fixed bases 5 are fixedly installed inside each of the lifting frames 4. Mounting frames 6 are mounted above each of the fixed bases 5. Conveyor wheels 7 are rotatably installed inside each of the mounting frames 6. Multiple evenly distributed H-shaped connecting frames 9 are fixedly installed inside each of the second lifting frames 8. Multiple evenly distributed ejector pins 10 are fixedly installed on the top of each of the second lifting frames 8 and the H-shaped connecting frames 9. The frame 1 contains a first lifting mechanism, a second lifting mechanism, and a steering mechanism. A collection groove 32 is provided inside the frame 1, with its bottom inclined. A sealing door 33 is rotatably installed on one side of the bottom of the frame 1. Specifically, the first lifting mechanism moves the lifting frame 11, lifting frame 2 15, multiple lifting frames 1 4, and multiple lifting frames 2 8 upwards. Multiple conveyor wheels 7 lift large finished products and scrap materials in the metal sheet. At this time, when the workers pull the large finished products and scrap materials, it is not only less labor-intensive but also has less friction, which is suitable for metal finished products with low precision requirements. When the precision requirements of the metal finished products are high, the second lifting mechanism first pushes the multiple lifting frames 2 8 and the multiple ejector pins 10 on their tops to a height higher than the multiple conveyor wheels 7. Then, the first lifting mechanism raises the whole structure. At this time, the multiple ejector pins 10 lift the large finished products and scrap materials. With the help of suction cups and other tools, the finished products are removed, avoiding damage to the bottom of the finished products caused by sliding friction and ensuring the quality of metal finished products with high precision requirements.

[0020] The first lifting mechanism includes a lifting frame 11 and two cylinders 12. The two cylinders 12 are symmetrically fixed inside the frame 1. The telescopic shaft ends of the two cylinders 12 are fixedly connected to both ends of the lifting frame 11. The two ends of the lifting frame 11 are slidably mounted on multiple evenly distributed guide rods 13. The multiple guide rods 13 are all fixedly mounted inside the frame 1. The bottom ends of multiple lifting frames 4 are all fixedly mounted with connecting rods 14. The bottom of the multiple connecting rods 14 are all fixedly connected to the lifting frame 11. The bottom ends of the lifting frame 11 are all fixedly mounted with auxiliary rods 34. The second lifting mechanism includes a second lifting frame 15 and two cylinders 16. The two cylinders 16 are fixedly installed at both ends of the top of two auxiliary rods 34. Auxiliary rods 35 are fixedly installed at both ends inside the second lifting frame 15. The telescopic shaft ends of the two cylinders 16 are fixedly connected to the two auxiliary rods 35. Multiple evenly distributed connecting rods 17 are fixedly installed at both ends of the top of the second lifting frame 15. The tops of the multiple connecting rods 17 are fixedly connected to their respective H-shaped connecting frames 9. Sliding sleeves 18 are slidably fitted onto the outside of each connecting rod 17. The ends of the multiple sliding sleeves 18 away from their respective connecting rods 17 are fixedly connected to their respective connecting rods 14. Multiple evenly distributed guide rods 19 are fixedly installed at both ends of the top of multiple lifting frames 8. The multiple guide rods 19 are slidably connected to their respective lifting frames 8. Specifically, the first lifting mechanism enables the lifting frame 11, lifting frame 2 15, multiple lifting frames 1 4, and multiple lifting frames 2 8 to move upward synchronously and stably. The second lifting mechanism enables the multiple lifting frames 2 8 to move upward stably, thereby making the height of the pin 10 in the multiple lifting frames 2 8 higher than the height of the multiple conveying wheels 7.

[0021] The steering mechanism includes a threaded rod 20 and a transmission assembly. The threaded rod 20 is threadedly connected to one end of the frame 1. An adjusting plate 21 is rotatably mounted on one end of the threaded rod 20. Guide rods 22 are slidably sleeved inside both ends of the adjusting plate 21. Both guide rods 22 are fixedly connected to the inner wall of the frame 1. Slide grooves 23 are opened at both ends of the adjusting plate 21. L-shaped adjusting rods 24 are slidably sleeved inside both slide grooves 23. Two annular limiting plates 25 are fixedly installed on the outside of the two L-shaped adjusting rods 24 near the end of the adjusting plate 21. The four annular limiting plates 25 are respectively set on both sides of the adjusting plate 21. The transmission assembly is set below the multiple lifting frames 4. The transmission assembly includes an adjusting frame 26. The top two ends of the adjusting frame 26 are slidably connected to their respective supporting frames 4. One side of the adjusting frame 26 is fixedly connected to two L-shaped adjusting rods 24. Multiple evenly distributed crossbars 27 are fixedly installed inside the adjusting frame 26. Multiple evenly distributed rotating shafts 28 are fixedly installed on the top of the adjusting frame 26 and the tops of the multiple crossbars 27. Sliding sleeves 29 are rotatably installed on the tops of the multiple rotating shafts 28. L-shaped rotating rods 30 are slidably fitted inside the multiple sliding sleeves 29. The tops of the multiple L-shaped rotating rods 30 are rotatably connected to their respective fixed bases 5, and the tops of the multiple L-shaped rotating rods 30 are fixedly connected to their respective mounting brackets 6. Two sliding sleeves 31 are slidably fitted at both ends of the adjusting frame 26. The tops of the four sliding sleeves 31 are fixedly fitted onto the outside of their respective supporting frames 4. Specifically, the pallet moves the adjusting plate 21 by rotating the threaded rod 20, and the two L-shaped adjusting rods 24 act on the adjusting frame 26. As the adjusting frame 26 and its internal multiple crossbars 27 move, multiple rotating shafts 28 move synchronously, multiple L-shaped rotating rods 30 rotate, and multiple conveying wheels 7 rotate, thereby adjusting the orientation when pulling large finished products and waste materials.

[0022] Working principle: In use, multiple metal plates to be processed are first placed on top of multiple grids 3. Multiple laser cutting devices 2 are used to laser cut the multiple metal plates respectively, achieving the effect of multi-station cutting. After cutting, small finished products and waste materials in the metal plates fall into the collection tank 32 through the gaps between multiple grids 3. Large finished products and waste materials remain on top of multiple grids 3. By opening the sealing door 33, the small finished products and waste materials inside the collection tank 32 can be taken out. Subsequently, two cylinders 12 are activated, driving the lifting frame 11 to move upward. The lifting frame 11 moves steadily upward along multiple guide rods 13. As the lifting frame 11 rises, the second lifting frame 15, multiple support frames 14, and multiple support frames 28 all move upward. Multiple conveyor wheels 7 and multiple ejector pins 10 also move upward. At this time, the height of the multiple ejector pins 10 is lower than the height of the multiple conveyor wheels 7, so the bottom of the multiple conveyor wheels 7 contacts the large finished products and waste materials in the metal sheet. As the lifting frame 11 rises, it lifts the large finished products and waste materials in the metal sheet. At this time, the workers can pull the large finished products and waste materials. Under the action of the multiple conveyor wheels 7, not only is it labor-saving, but the friction is also small, which is suitable for metal finished products with low precision requirements, thus improving the cutting effect of the laser cutting machine on metal. By rotating the threaded rod 20, the adjusting plate 21 moves under the action of the two guide rods 22. At the same time, under the action of the four annular limiting plates 25, the two L-shaped adjusting rods 24 move synchronously with the adjusting plate 21. The two L-shaped adjusting rods 24 push the adjusting frame 26 and multiple crossbars 27 to move synchronously. The adjusting frame 26 moves stably under the action of multiple sliding sleeves 31. As the adjusting frame 26 and multiple crossbars 27 move, multiple rotating shafts 28 move synchronously. Multiple sliding sleeves 29 slide outside their respective L-shaped rotating rods 30. The multiple L-shaped rotating rods 30 rotate around their respective fixed bases 5 under force. Multiple mounting frames 6 and multiple conveying wheels 7 rotate. At this time, the orientation when pulling large finished products and waste materials can be adjusted to meet the different usage needs of the staff. During the upward movement of multiple lifting frames 4, the adjusting frame 26 moves synchronously with it. The adjusting frame 26 drives the two L-shaped adjusting rods 24 to slide inside the two slide grooves 23 respectively. When the precision requirements of the finished metal product are high, the two cylinders 16 are activated first, which push the lifting frame 15 upward. At this time, the multiple supporting frames 8 move upward through their respective connecting rods 17. The multiple connecting rods 17 move upward along their respective sliding sleeves 18. As the multiple supporting frames 8 move upward, the multiple ejector pins 10 also move upward. At this time, the height of the multiple ejector pins 10 is higher than the height of the multiple conveying wheels 7. Then, the first lifting mechanism lifts the lifting frame 11 to the top. At this time, the multiple ejector pins 10 lift the large finished product and waste material, so that the bottom of the finished product is separated from the multiple rough grids 3. The workers then use suction cups and other tools to remove the finished product, avoiding damage to the bottom of the finished product caused by sliding friction, and ensuring the quality of the finished metal product with high precision requirements.
