Description

Technical Field

[0001] This invention belongs to the field of laser cladding equipment technology, and particularly relates to a blue laser cladding system with a sealed working box. Background Technology

[0002] Laser cladding is an advanced surface treatment technology that uses a high-energy laser beam as a heat source to coat one or more materials onto the surface of a substrate material, thereby improving the material's wear resistance, corrosion resistance, heat resistance, and other properties. This technology is widely used in industry, particularly in aerospace, automotive, mold manufacturing, and energy sectors. Laser cladding originated in the 1980s. With the maturation of laser technology and increased power, lasers began to be used in more complex material processing processes, including surface cladding. During this period, researchers began exploring the use of lasers to clad metal surfaces to improve properties such as wear resistance and corrosion resistance. In the 21st century, laser cladding technology has become a mature industrial technology field, applied to improve and repair the surface properties of high-value components, particularly in aerospace, automotive, and mold manufacturing. In recent years, with the rise of 3D printing technology, the combination of laser cladding technology and additive manufacturing technology has become a new research and application hotspot. When laser cladding highly conductive materials such as copper, silver, and gold, blue laser cladding of copper and silver can form a stable cladding layer due to its high energy absorption efficiency. Metallographic observation after cladding shows that the cladding layer has a dense structure and high bonding strength. This technology is also suitable for high-temperature wear-resistant coating cladding on copper, and the cladding layers are completely metallurgically bonded to each other, without the substrate peeling off from the cladding layer.

[0003] However, existing technologies have some problems: conventional laser cladding typically involves cladding parts exposed to the outside, but some special parts require cladding in a vacuum environment. This necessitates the use of a sealed chamber, where the air is evacuated to create a vacuum environment for cladding. During the cladding process, a protective gas is injected into the sealed chamber. However, existing sealed chambers only have one sealed door. In continuous cladding processes, the repeated opening and closing of the door affects the sealing environment of the chamber. Each time the door is opened and closed, the internal air needs to be evacuated to create a vacuum environment, which severely impacts production efficiency. Furthermore, different protective gases are injected during the cladding process, and gas is lost each time the door is opened. The protective gas needs to be refilled during the cladding process, resulting in cost losses and waste. Therefore, we propose a blue laser cladding system with a sealed working chamber. Summary of the Invention

[0004] To address the problems existing in the prior art, the purpose of this invention is to provide a blue laser cladding system with a sealed working chamber. A transfer chamber is set on one side of the cladding chamber, and a sealing door is installed between the transfer chamber and the cladding chamber. The cladding chamber closes with the sealing door to form a sealed cavity, and a transfer door is set on one side of the transfer chamber, which also closes with the sealing door to form a sealed cavity, thus forming two sets of sealed cavities. Each time a part is picked up or placed, the part is placed in the transfer chamber, and then the air in the transfer chamber is evacuated to form a vacuum chamber. The sealing door is then opened by an opening assembly, and the conveying assembly and electric guide rail work together to place the part in the transfer chamber onto the heating base to await cladding. This solves the problem of the vacuum environment in the cladding chamber being disrupted when the cladding door is opened, causing the protective gas to leak out and requiring the air to be evacuated again to form a vacuum chamber. This ensures that the cladding chamber is always in a vacuum environment, preventing the protective gas from leaking out and reducing unnecessary waste of protective gas.

[0005] Each time a cladding part is picked up or placed, it is placed in the cladding chamber through the transfer chamber to ensure that the cladding chamber is always in a vacuum environment, so that the protective gas in the cladding chamber will not be lost and unnecessary waste of protective gas is reduced.

The transfer chamber is closed with the sealing door to form a sealed chamber, thus forming two sets of sealed chambers. Each time a part is picked up or put down, the part is placed in the transfer chamber, and then the air in the transfer chamber is evacuated to form a vacuum chamber. This facilitates the connection with the vacuum environment in the cladding chamber and prevents damage to the hollow environment of the cladding chamber. At the same time, the small internal volume of the transfer chamber allows for rapid air extraction to form a vacuum environment, further improving the speed of connection with the cladding chamber. At the same time, the sealing door is opened by the door opening assembly, and then the conveying assembly and electric guide rail work together to place the part in the transfer chamber onto the heating base to await the cladding work. This solves the problem of the vacuum environment in the cladding chamber being destroyed when the cladding door is opened, the loss of protective gas, and the need to re-evacuate air to form a vacuum chamber. This ensures that the cladding chamber is always in a vacuum environment, and the protective gas in the cladding chamber is not lost, reducing unnecessary waste of protective gas.

[0029] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0030] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0031] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0032] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0033] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0034] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0035] like Figures 1 to 9As shown in the figure, an embodiment of the present invention provides a blue laser cladding system with a sealed working box, comprising: an equipment box 1, a cladding chamber 2 disposed on one side of the equipment box 1, a cladding door 3 disposed on one side of the cladding chamber 2, a transfer chamber 6 disposed at one end of the equipment box 1, the transfer chamber 6 communicating with the cladding chamber 2, a sealing door 7 disposed between the transfer chamber 6 and the cladding chamber 2, the cladding chamber 2 being closed through the cladding door 3 and the sealing door 7 to form a sealed chamber, and a transfer door 10 disposed at one end of the transfer chamber 6. Typically, only one cladding door 3 is used to form the sealed chamber. Opening the cladding door 3 multiple times during the cladding process will disrupt the vacuum of the sealed chamber and cause the loss of protective gas, thus increasing the cost of cladding the parts. Therefore, a transfer chamber 6 is set on one side of the cladding chamber 2 and the cladding chamber 2 is separated from the transfer chamber 6 by a sealing door 7. Each time a part is picked up or put down, the cladding part is picked up or put down through the transfer chamber 6 to ensure that the cladding chamber 2 is always in a vacuum environment, so that the protective gas in the cladding chamber 2 will not be lost, reducing the use of protective gas and thus reducing the gas supply cost during the cladding process. When a vacuum environment is not required for cladding, the cladding door 3 can be opened and the part can be placed directly in the cladding chamber 2 for cladding. At the same time, the transfer chamber 6 has a small internal volume and can quickly extract air to form a vacuum environment, further improving the docking speed with the cladding chamber 2. The cladding door 3 can be opened to facilitate maintenance inside the cladding chamber 2.

[0036] The cladding chamber 2 is equipped with a first robotic arm 4 and a heating base 11. The bottom of the heating base 11 is equipped with a heat insulation plate, which is used to isolate the heat of the heating base 11 from the heat transfer to the bottom wall of the cladding chamber 2, preventing damage to the bottom wall of the cladding chamber 2. The heating base 11 adopts a YCKTR type cast aluminum heating plate. The cast aluminum heating plate is a heater with uniform heat distribution and thermal conductivity metal alloy, which ensures uniform temperature of the hot surface, eliminates hot and cold spots of the equipment, and has the advantages of long service life, good heat preservation performance, strong mechanical properties and resistance to magnetic fields. By adding a heat preservation device to the outer heat dissipation surface and sintering infrared rays on the inner heat dissipation surface, it can save 35% of electricity. The heating base 11 is used to heat the cladding parts, so that the parts can be fully fused with the cladding coating during the cladding process. The hardness, strength and stability of the material of the parts after heat treatment and cladding can be improved, thereby improving the cladding quality of the product.

[0037] The first robotic arm 4 is equipped with a laser cladding gun 5 at one end. The first robotic arm 4 is a five-axis robotic arm, capable of highly precise positioning and movement. Its control system can finely control parameters such as the position, speed, and acceleration of each joint, thereby achieving high-precision operation. It can operate at different angles and directions, and its workspace is larger than other robotic arms, adapting to more application scenarios. It can also be autonomously controlled through programming or connected to external devices for control. This allows the robotic arm to have richer functions and greater flexibility, adapting to different application needs and facilitating multi-angle cladding of parts by the laser cladding gun 5.

[0038] The laser source of the laser cladding gun 5 is a blue laser source. Compared with infrared laser sources, blue laser cladding additive manufacturing has a higher speed. Specifically, it adopts a Laserline-LDM-1500-100blue laser emitter. As we all know, copper has a very low absorption rate of infrared lasers, but a very high absorption rate of blue light. Almost every reflective metal has a much higher absorption rate of blue light than infrared light. The spot energy distribution of blue laser also makes the melting of the melt stable, improves the quality of the finished product, and enables the coating of the cladding part to form a good metallurgical bond with the substrate. Moreover, there is no spatter during the cladding welding process, which is incomparable to traditional red lasers.

[0039] An opening assembly 8 is provided on one side of the sealing door 7. The opening assembly 8 is located inside the cladding chamber 2. An electric guide rail 17 is provided inside the cladding chamber 2. The electric guide rail 17 is positioned opposite to the first robotic arm 4 and is located on one side of the cladding door 3. A conveying assembly 9 is provided on the moving end of the electric guide rail 17. Since the cladding chamber 2 and the transfer chamber 6 are in a sealed state, it is not easy to transfer the cladding parts between the cladding chamber 2 and the transfer chamber 6. Therefore, the opening assembly 8 is provided to open and close the sealing door 7. At the same time, the electric guide rail 17 and the conveying assembly 9 cooperate with each other to transfer the cladding parts between the cladding chamber 2 and the transfer chamber 6. The operator only needs to place or remove the cladding parts in the transfer chamber 6. In addition, the sealing door 7 adopts an upward opening method, which occupies less space than an outward opening door, reducing the area occupied in the cladding chamber 2.

[0040] The equipment box 1 has a vacuum space 13 and an air filling room 14 on both sides at one end. The vacuum space 13 is equipped with a vacuum pump 15. The suction port of the vacuum pump 15 is connected to the cladding chamber 2 and the transfer chamber 6 respectively. Both the cladding chamber 2 and the transfer chamber 6 are equipped with vacuum pressure sensors. The vacuum sensors are SSM-P202S type vacuum sensors, which are used to detect the vacuum pressure in the cladding chamber 2 and the transfer chamber 6 to facilitate the judgment of whether the internal vacuum environment meets the vacuum requirements. By opening the transfer door 10, the cladding parts in the transfer chamber 6 are placed, and then the transfer door 10 is closed. At this time, the vacuum pump 15 sucks away the air in the transfer chamber 6 to form a vacuum environment. At the same time, the door opening assembly 8 opens the sealing door 7. The electric guide rail 17 and the conveying assembly 9 work together to take the parts in the transfer chamber 6 and place them in the cladding chamber 2. At the same time, the door opening assembly 8 closes the sealing door 7.

[0041] The filling chamber 14 is equipped with multiple gas cylinders 16, each with an electric valve 12 at its gas inlet. The electric valve 12 is a D71X-10DN50 electric butterfly valve, featuring a tightening seal as it closes, ensuring reliable sealing. The sealing material is nitrile oil-resistant rubber, offering a long service life. The butterfly plate has a frame structure, providing high strength, a large flow area, low flow resistance, and bidirectional sealing. Installation is unaffected by the direction of medium flow or spatial location, allowing for installation in any orientation. The electric valve 12 controls the opening and closing of the gas inlets of the gas cylinders 16, facilitating the filling of the cladding chamber 2 with the required protective gas. The multiple electric valves 12... A gas supply pipe 21 is connected to reduce the number of pipe connections. Multiple cylinders are connected by the gas supply pipe 21, which is connected to a gas supply main pipe 22. The gas in the gas supply pipe 21 is transported to the cladding chamber 2 by the gas supply main pipe 22. When multiple sets of gas protection are required, multiple electric valves 12 can be controlled to open and output the gas in the gas supply pipe 21, which is then input into the cladding chamber 2 by the gas supply main pipe 22. The gas supply main pipe 22 is connected to the cladding chamber 2. Multiple gas tanks 16 store different types of gases, such as helium, argon, and nitrogen, for protection. This facilitates the protection of the parts during the cladding process and can obtain a higher purity and more uniform cladding layer.

[0042] The conveying assembly 9 includes a second robotic arm 901, which is mounted on the movable end of the electric guide rail 17. One end of the second robotic arm 901 is equipped with a gripper 902. The second robotic arm 901 is an eight-axis robotic arm, which can rotate and adjust at multiple angles. This facilitates the second robotic arm 901 and the gripper 902 to cooperate in picking up the cladding parts and placing them in the transfer chamber 6.

[0043] The gripper 902 includes two sets of first gripping arms 9021, one end of which engages with a second gripping arm 9022. Both sets of first gripping arms 9021 and the two sets of second gripping arms 9022 have arc-shaped grooves on their opposing surfaces. These grooves cooperate to form a ring shape, facilitating the gripping of objects of various shapes. Multiple anti-slip strips are provided within the arc-shaped grooves to reduce friction between the gripper 902 and the cladding part, further strengthening the gripping strength and preventing the part from slipping. Multiple clamping blocks, similar in shape to the first gripping arms 9021, are provided between the two sets of first gripping arms 9021. These blocks increase the gripping area of ​​the clamped part, thereby increasing the gripping area and enhancing the gripping stability. The two sets of second gripping arms... A worm gear 9023 is fixedly installed between two sets of first clamping arms 9021 or two sets of second clamping arms 9022. The worm gear 9023 is meshed with a second worm wheel 9024. A third motor 9025 is fixedly installed at one end of the second worm wheel 9024. The third motor 9025 drives the second worm wheel 9024 to drive the worm gear 9023 to rotate, so that one end of the first clamping arm 9021 and the second clamping arm 9022 meshes and rotates, while the other end is close to or far away, thereby realizing the opening or closing of the gripper 902. The surfaces of the two sets of first clamping arms 9021 and the two sets of second clamping arms 9022 are covered with U-shaped blocks 9026. A tray 9027 for placing the third motor 9025 is provided inside the U-shaped blocks 9026.

[0044] The door opening assembly 8 includes four sets of support rods 801, which are rotatably located at the four corners of the sealing door 7. One end of each support rod 801 is rotatably connected to a movable block 802. A first threaded post 803 is threaded between two sets of movable blocks 802. The threads of the two sets of movable blocks 802 are in opposite directions. Both ends of the first threaded post 803 are rotatably connected to a first fixing plate 18. A movable plate 804 is fixedly installed at one end of each of the four sets of first fixing plates 18. The first fixing plate 18 fixes the first threaded post 803 to one side of the movable plate 804. At the same time, the first fixing plate 18 restricts the movement range of the movable block 802. By rotating the first threaded post 803, the two sets of movable blocks 802 move closer or further away from each other following the rotation direction of the first threaded post 803, thereby adjusting the angle of the support rod 801. This allows the support rod 801 to push the sealing door 7 out or retract it. When pushed out, one side of the sealing door 7 is tightly fitted into the sealing groove in the transfer chamber 6 to enhance the sealing between the transfer chamber 6 and the cladding chamber 2.

[0045] Two sets of first fixed plates 18 are rotatably connected to one end of a first drive roller 805. One end of the first drive roller 805 passes through the first fixed plate 18 and is rotatably connected to the first threaded column 803. The surfaces of the two sets of first drive rollers 805 are meshed with a toothed belt 806. One end of the movable plate 804 is fixedly mounted with a first motor 808. One end of the output shaft of the first motor 808 is fixedly mounted with a second drive roller 807. The second drive roller 807 is meshed with the toothed belt 806. The two sets of first threaded columns 803 are driven by the two sets of first drive rollers 805 and the toothed belt 806, causing the first threaded columns 803 to rotate, thereby adjusting the sealing performance between the sealing gate 7 and the transfer chamber 6 and the cladding chamber 2. The toothed belt 806 is driven by the second drive roller 807, which rotates on the output shaft of the first motor 808.

[0046] Movable blocks 809 are provided on both sides of one end of the movable plate 804. The movable blocks 809 are threadedly connected to second threaded posts 810. The laying direction of the second threaded posts 810 determines the moving direction of the sealing door 7. The two ends of the second threaded posts 810 are rotatably connected to second fixed plates 19. The second fixed plates 19 fix the second threaded posts 810 to one side inside the cladding chamber 2, and at the same time restrict the movement range of the movable blocks 809. One end of each of the two sets of second fixed plates 19 is rotatably connected to a first bevel gear 811. The first bevel gear 811 meshes with a second bevel gear 811. A rotating rod 813 is fixedly installed between two sets of second bevel gears 812. The rotation of the rotating rod 813 causes the second bevel gears 812 at both ends to drive the two sets of first bevel gears 811 to rotate, causing the second threaded column 810 to rotate. This causes the movable block 809 to move up or down on the surface of the second threaded column 810, thereby opening or closing the connection between the sealing door 7 and the cladding chamber 2. Two sets of third fixing plates 20 are rotatably connected to the surface of the rotating rod 813. One end of each set of third fixing plates 20 is fixedly installed on the inner wall of the cladding chamber 2.

[0047] The rotating rod 813 has a worm gear 814 on its surface, which meshes with a first worm wheel 815. A second motor 816 is fixedly installed at one end of the first worm wheel 815, and the second motor 816 is fixedly installed at one end of the inner wall of the cladding chamber 2. The output end of the second motor 816 drives the first worm wheel 815 to rotate. The worm gear 814 on the surface of the rotating rod 813 rotates under the drive of the first worm wheel 815, thereby providing rotational power to the second threaded column 810.

[0048] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
