Description

Technical Field

[0001] This invention relates to the field of aluminum laser engraving technology, specifically to a rotary automated laser engraving machine for aluminum processing. Background Technology

[0002] In the aerospace field, aluminum is widely used in key parts such as fuselage structure, engine components and skin due to its high strength, lightweight and corrosion resistance. The processing of aerospace aluminum materials has extremely high requirements for precision, surface quality and material integrity. Therefore, it is necessary to use a high-precision automated laser engraving machine for engraving.

[0003] Existing technology (Chinese patent publication number: CN117697165A, publication date: 2024-03-15) discloses a laser engraving device and method for aluminum-plated decorative frames, belonging to the field of laser engraving technology. The laser engraving device for aluminum-plated decorative frames includes a base with a conveying mechanism for transporting workpieces; a hopper located directly above one end of the conveying mechanism, with a positioning structure and a retaining structure on the hopper, the retaining structure located below the positioning structure; a transmission mechanism located directly above the conveying mechanism, used to drive the conveying mechanism, retaining structure, and positioning structure to move; a worktable located at the discharge end of the conveying mechanism, fixed to the base, with a positioning and clamping structure for positioning and clamping workpieces on the worktable, the transmission mechanism driving the workpiece to slide on the worktable; and a laser engraving machine located on one side of the worktable. Using the aforementioned laser engraving device and method for aluminum-plated decorative frames, the workpieces are automatically loaded, clamped, and unloaded, improving the degree of automation and effectively increasing processing efficiency.

[0004] Existing technology (Chinese Patent No. CN113084359B, Publication Date: July 9, 2021) discloses a laser engraving device and method. The laser engraving device includes a laser engraving machine, a drive unit, a control unit, a rotating shaft, and a horizontal adjustment unit. The rotating shaft is equipped with a clamp for holding the product to be laser engraved. The drive unit drives the rotating shaft to rotate. The horizontal adjustment unit keeps the rotating shaft horizontal. The control unit controls the operation of the drive unit according to the drive pulse signal sent by the laser engraving machine. When the product to be laser engraved is driven to rotate by the drive unit, the laser engraving machine laser engraves a mark on the product. This allows for printing marks on multiple sides of the product at once, and also enables large-area, large-arc printing on the 360-degree circumferential surface and curved surfaces of the product. By automatically rotating the product, the efficiency of printing marks is improved, and the labor intensity of printing marks is reduced.

[0005] Although existing laser engraving machines can rotate and adjust the workpiece, their clamping structure uses a single opposing clamping method, which cannot adaptively adjust the clamping force before rotation. This makes the workpiece prone to positional shift due to gravity during rotation, thus reducing the laser engraving accuracy and presenting certain defects in use. Summary of the Invention

[0006] The purpose of this invention is to provide a rotary automated laser engraving machine for aluminum processing, in order to solve the problem mentioned in the background art that the clamping structure of current laser engraving machines on the market adopts a single opposing clamping, which cannot adaptively adjust the clamping force before rotation, making the workpiece prone to positional displacement due to gravity during rotation.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a rotary automated laser engraving machine for aluminum processing, comprising a frame, a laser engraving mechanism mounted on the upper inner side of the frame, and a fixed frame fixedly mounted on the upper inner side of the frame, and a clamping assembly for clamping aluminum material mounted on the fixed frame, the clamping assembly comprising a hollow adjusting shaft rotatably mounted on the fixed frame, and a rotary motor for driving the adjusting shaft to rotate via a synchronous belt pulley fixedly mounted on the fixed frame, and a clamping frame fixedly mounted at the end of the adjusting shaft near the aluminum material, while lifting and adjusting clamping plates are symmetrically mounted on the clamping frame, an adsorption component for adsorbing the surface of the aluminum material is provided on the clamping plate, and a heat-conducting component for adjusting the heat of the aluminum material is also provided on the clamping plate, and a heat control adjustment component for improving the adsorption effect through heat is connected between the heat-conducting component and the adsorption component.

[0008] Preferably, the clamping frame is arranged in a C-shape, and a clamping motor is fixedly installed on the top of the clamping frame. An adjusting screw is fixedly installed on the output end of the clamping motor. At the same time, the threads at both ends of the adjusting screw are opposite in direction. The adjusting screw is threadedly connected to the clamping plate, and during the rotation of the adjusting screw, it drives the two clamping plates on the same side to move relative to each other to achieve clamping of the aluminum material.

[0009] Preferably, the adsorption assembly includes an adsorption element that slides through the clamping plate, and the lower end of the adsorption element is sealed and attached to the outside of the aluminum material during the clamping process of the clamping plate, and a first spring is fixedly connected between the adsorption element and the clamping plate.

[0010] Preferably, guide rails are symmetrically fixedly installed on the outer side of the clamping plate, and sliders are slidably installed on the inner side of the guide rails. A guide rod is slidably installed through the end of the adsorption component away from the aluminum material. At the same time, a sealing plug is fixedly installed at the end of the guide rod located inside the adsorption component. The sealing plug is interference-slidably installed inside the adsorption component. A second spring is fixedly connected between the adsorption component and the sealing plug. A pull cable is fixedly connected between the slider and the sealing plug. During the movement of the adsorption component, the pull cable pulls the sealing plug to slide inside the adsorption component.

[0011] Preferably, the vertical portion of the clamping plate is symmetrically provided with inclined through-type guide grooves, and the heat-conducting component includes a heat exchanger slidably mounted on the guide groove. Both the clamping plate and the heat exchanger have hollow inner sides, and the inner cavities of the adjusting shaft, clamping plate, and heat exchanger are all filled with heat exchange oil. The adjusting shaft, clamping plate, and heat exchanger are all made of heat-conducting metal material. A connecting end cap is rotatably mounted on the end of the adjusting shaft, and the connecting end cap is connected to the oil circulation cooling pipeline through a pipe. The adjusting shaft and clamping plate, and the clamping plate and heat exchanger are all connected through pipes to realize the circulation and transportation of oil.

[0012] Preferably, the outer side of the heat exchanger is fitted with a heat-conducting sleeve, and an elastic heat-conducting element of elastic material is connected between the heat exchanger and the heat-conducting sleeve. The heat-conducting sleeve is always in contact with the aluminum surface under the elastic force of the elastic heat-conducting element.

[0013] Preferably, during the rotation of the clamping frame, the heat exchanger slides along the guide groove, and when the heat exchanger is above the aluminum material, it slides to the edge of the aluminum material, and when the heat exchanger is below the aluminum material, it slides to the middle of the aluminum material.

[0014] Preferably, the thermal control adjustment component includes a shape memory metal sheet fixedly inserted into the cavity of the clamping plate, and a heat-conducting sheet is uniformly fixedly installed on the outer side of one end of the shape memory metal sheet located on the inner side of the clamping plate, and the heat-conducting sheet is immersed in the oil in the cavity of the clamping plate.

[0015] Preferably, the upper end of the memory metal sheet is disposed through the inner side of the guide rail, and the end of the memory metal sheet is attached to the slider. The upper part of the memory metal sheet is curved, and the memory metal sheet pushes the slider to slide along the guide rail to pull the cable after being heated and deformed.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the rotary automated laser engraving machine for aluminum processing can achieve stable clamping and angle adjustment of aluminum materials, and can ensure that the aluminum materials are heated evenly during the laser engraving process, avoiding excessive local temperature differences that could lead to internal stress affecting the processing quality of aluminum materials. The specific details are as follows.

[0017] 1. Equipped with an adjusting shaft and clamping plate, the clamping motor drives the adjusting screw to rotate, which allows the clamping plate to clamp and fix both ends of the aluminum material. During the clamping process, the adsorption component will automatically adsorb onto the outside of the aluminum material, thereby effectively improving the clamping stability of the aluminum material. Subsequently, the adjusting shaft can drive the clamping plate to rotate, thereby switching the laser engraving position of the aluminum material.

[0018] 2. Equipped with an adjusting shaft, clamping plate, and heat exchanger, the heat exchanger can be synchronously rotated by the clamping plate as the clamping frame rotates. This allows the heat exchanger to slide along the guide groove under gravity, thereby adjusting its position. At the same time, the heat-conducting sleeve on the outside of the heat exchanger is always in contact with the outside of the aluminum material under the elastic force of the elastic heat-conducting component, thus transferring the heat from the laser engraving area to the edge of the aluminum material. This reduces the temperature difference between different parts of the aluminum material and avoids generating large stresses that could affect the processing quality.

[0019] 3. Equipped with a slider and an elastic heat-conducting component, after laser engraving on one side is completed, the temperature of the oil inside the clamp increases, thereby heating the elastic heat-conducting component and causing it to deform. During the deformation process, the elastic heat-conducting component pushes the slider to slide inside the guide rail and away from the adsorption component. This allows the slider to pull the sealing plug through the cable to move further inside the adsorption component, thereby further reducing the air pressure inside the adsorption component. This prevents the aluminum material from shifting due to insufficient lateral force during rotation, thus effectively ensuring the laser engraving accuracy of the aluminum material.

[0031] 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.

[0032] Example 1: Existing laser engraving machines have a simple fixture structure, which cannot ensure the positioning stability of the aluminum material during fixture rotation, thus easily affecting laser engraving accuracy. To solve this technical problem, this example discloses the following technical content. Please refer to [link / reference]. Figures 1-5 and Figures 7-8 As shown; a rotary automated laser engraving machine for aluminum processing includes a frame 1, a laser engraving mechanism 2 installed on the upper inner side of the frame 1, and a fixed frame 3 fixedly installed on the upper inner side of the frame 1, and a clamping assembly for clamping aluminum is installed on the fixed frame 3; the clamping assembly includes a hollow adjusting shaft 5 rotatably mounted on the fixed frame 3, and a rotary motor 4 that drives the adjusting shaft 5 to rotate via a synchronous belt pulley is fixedly mounted on the fixed frame 3, and a clamping frame 7 is fixedly mounted on the end of the adjusting shaft 5 near the aluminum material, while lifting and adjusting clamping plates 10 are symmetrically mounted on the clamping frame 7.

[0033] The clamping frame 7 is arranged in a C-shape, and a clamping motor 8 is fixedly installed on the top of the clamping frame 7. An adjusting screw 9 is fixedly installed on the output end of the clamping motor 8. At the same time, the threads at both ends of the adjusting screw 9 are opposite in direction. The adjusting screw 9 is threadedly connected to the clamping plate 10. During the rotation of the adjusting screw 9, it drives the two clamping plates 10 on the same side to move relative to each other to achieve clamping of the aluminum material.

[0034] like Figures 4-5 As shown, the aluminum material is transported between the clamping plates 10 by the feeding equipment, and the clamping motor 8 is controlled to drive the adjusting screw 9, so that the adjusting screw 9 drives the two clamping plates 10 to move closer to each other, thereby achieving the clamping and fixing of the edge position of the aluminum material.

[0035] The clamping plate 10 is provided with an adsorption assembly for adsorbing aluminum material onto the surface. The adsorption assembly includes an adsorption element 11 that slides through the clamping plate 10. During the clamping process of the clamping plate 10, the lower end of the adsorption element 11 is sealed and attached to the outside of the aluminum material. A first spring 12 is fixedly connected between the adsorption element 11 and the clamping plate 10. A guide rail 13 is symmetrically fixedly installed on the outside of the clamping plate 10. A slider 14 is slidably installed on the inside of the guide rail 13. A guide rod 15 is slidably installed through the end of the adsorption element 11 away from the aluminum material. A sealing plug 16 is fixedly installed at the end of the guide rod 15 located inside the adsorption element 11. The sealing plug 16 is interference-slidably installed inside the adsorption element 11. A second spring 17 is fixedly connected between the adsorption element 11 and the sealing plug 16. A pull cable 18 is fixedly connected between the slider 14 and the sealing plug 16. During the movement of the adsorption element 11, the pull cable 18 pulls the sealing plug 16 to slide inside the adsorption element 11.

[0036] like Figures 7-8 As shown, as the clamping plate 10 moves and approaches the aluminum material, the end of the adsorption member 11 will first contact the surface of the aluminum material, thereby sealing and adhering to the outside of the aluminum material. As the clamping plate 10 continues to move, the adsorption member 11 can be elastically stretched and adjusted on the clamping plate 10. At this time, the slider 14 will pull the sealing plug 16 through the cable 18 to slide in an interference fit on the inside of the adsorption member 11, thereby reducing the air pressure between the adsorption member 11 and the aluminum material, thereby achieving automatic adsorption of the aluminum material and further improving the clamping and positioning effect of the aluminum material. At this time, the slider 14 will be prevented from sliding towards the adsorption member 11 by the blocking of the positioning block inside the guide rail 13.

[0037] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. Existing laser engraving machines cannot adjust the overall heating of the aluminum material during operation, making local temperature differences prone to be too large and failing to reduce the impact of heat changes on clamping stability. To further solve this technical problem, this example discloses the following technical content: Figures 5-10As shown; the clamping plate 10 is also equipped with a heat-conducting component for regulating the heat of the aluminum material, and a heat control regulating component that improves the adsorption effect by heat is connected between the heat-conducting component and the adsorption component. The vertical part of the clamping plate 10 is symmetrically provided with inclined through-type guide grooves 21, and the heat-conducting component includes a heat exchanger 22 that is slidably installed on the guide groove 21. The inner sides of both the clamping plate 10 and the heat exchanger 22 are hollow structures, and the inner cavities of the adjusting shaft 5, the clamping plate 10, and the heat exchanger 22 are all filled with heat exchange oil. At the same time, the adjusting shaft 5, the clamping plate 10, and the heat exchanger 22 are all made of heat-conducting metal material, and a connecting end cap 6 is rotatably installed at the end of the adjusting shaft 5. Furthermore, the connecting end cap 6 is connected through pipes and oil circulation cooling pipes, and the adjusting shaft 5 and the clamping plate 10, and the clamping plate 10 and the heat exchanger 22 are all connected through pipes to realize oil circulation transportation. The heat exchanger 22 is fitted with a heat-conducting sleeve 23 on its outer side, and an elastic heat-conducting element 24 of elastic material is connected between the heat exchanger 22 and the heat-conducting sleeve 23. Under the elastic force of the elastic heat-conducting element 24, the heat-conducting sleeve 23 always fits against the surface of the aluminum material. During the rotation of the clamping frame 7, the heat exchanger 22 slides along the guide groove 21. When the heat exchanger 22 is above the aluminum material, it slides to the edge of the aluminum material, and when the heat exchanger 22 is below the aluminum material, it slides to the middle of the aluminum material.

[0038] like Figures 5-7 as well as Figure 10 As shown, when the clamping plate 10 clamps the aluminum material, the heat exchanger 22 and the heat-conducting sleeve 23 located below the aluminum material are close to the laser-engraved position in the middle of the aluminum material, which can conduct the heat generated during the laser engraving process. At the same time, since the space inside the adjusting shaft 5, the clamping plate 10 and the heat exchanger 22 is connected by pipes, the heat can be quickly conducted, thereby effectively reducing the temperature of the laser-engraved position. Meanwhile, the oil that has absorbed heat can heat the edge of the aluminum material through the clamping plate 10 and the heat exchanger 22 located above the aluminum material, thereby reducing the temperature difference between different parts of the aluminum material and reducing the internal stress change of the aluminum material to ensure the processing quality of the aluminum material. When the aluminum material needs to be rotated, the heat exchanger 22 can slide along the guide groove 21 under the action of gravity, thereby adjusting the position of the heat exchanger 22, so that the heat exchanger 22 located above the aluminum material is always located at the edge, while the heat exchanger 22 located below the aluminum material is always close to the middle laser-engraved position, which is conducive to heat conduction and control.

[0039] The thermal control adjustment assembly includes a shape memory metal sheet 19 fixedly inserted into the cavity of the clamping plate 10. A heat-conducting plate 20 is uniformly fixedly installed on the outer side of one end of the shape memory metal sheet 19 located inside the clamping plate 10. The heat-conducting plate 20 is immersed in the oil in the cavity of the clamping plate 10. The upper end of the shape memory metal sheet 19 is disposed through the inner side of the guide rail 13. The end of the shape memory metal sheet 19 is attached to the slider 14. The upper part of the shape memory metal sheet 19 is curved. When the shape memory metal sheet 19 is heated and deformed, it pushes the slider 14 to slide along the guide rail 13 to pull the cable 18.

[0040] like Figures 8-10 As shown, as the laser engraving proceeds, the temperature of the oil inside the clamping plate 10 gradually increases. The oil exchanges heat through the heat-conducting plate 20 and the shape memory metal sheet 19, thereby heating the shape memory metal sheet 19 and causing it to undergo elastic deformation. The deformed shape memory metal sheet 19 pushes the slider 14 to slide along the guide rail 13 away from the adsorption component 11. The slider 14 further pulls the sealing plug 16 in the guide rail 13 via the cable 18, thereby further reducing the air pressure inside the adsorption component 11. This eliminates the influence of temperature changes on the adsorption force during the laser engraving process, ensuring the stability of the aluminum material during subsequent rotation and preventing positional shifts or even slippage that could affect processing accuracy.

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.
