Description

Technical Field

[0001] This utility model relates to the field of rust removal and painting technology for round pipes, and in particular to an automatic laser rust removal and painting device for the surface of round pipes. Background Technology

[0002] Rust removal is a prerequisite for painting. Rust on the surface of the round pipe is removed by mechanical or chemical methods, and then painting is carried out. The paint layer can act as a protective barrier for the round pipe, isolating it from contact with oxygen, water vapor, and corrosive media in the air, thereby effectively slowing down the rate of rusting and extending the service life of the round pipe.

[0003] Existing rust removal equipment is mostly single-function rust removal devices, such as common shot blasting machines and laser rust removal machines. After completing the rust removal process on round pipes, these devices need to transfer the pipes to the painting area for subsequent painting operations. However, this separate operation mode has many drawbacks. On the one hand, during the waiting and transfer process between rust removal and painting, the metal substrate on the surface of the round pipe is in a relatively exposed state. If the ambient humidity is high, corrosive gases are present, or there is sufficient contact with oxygen in the air, oxidation reactions can easily occur, leading to secondary rusting. This not only reduces the corrosion resistance of the round pipe but may also affect the quality of subsequent painting, such as reducing paint film adhesion and causing peeling or flaking. This increases the frequency of repairs and rework, wasting a lot of manpower, material resources, and time. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] Please refer to Figure 1 The present invention provides an automatic laser rust removal and painting treatment device for the surface of a round tube, including a first support roller assembly 5, a laser rust removal device 6, a crane mechanism 4, a painting mechanism 8 and a transfer assembly 7, as well as an AGV transport vehicle 14 and a temporary storage rack 13. The first support roller assembly 5, the laser rust removal device 6, the crane mechanism 4, the painting mechanism 8 and the transfer assembly 7 are all controlled by an electrical control cabinet 2 located in the treatment room 1.

[0036] Processing room 1 is the installation and working space for the entire device. Its internal layout is reasonable, providing a good environment for the installation of various components and the processing of round pipes.

[0037] Example 1: The first support roller assembly 5 is installed in the processing chamber 1 to support and rotate the round pipe to be derusted.

[0038] The laser rust removal device 6 is movably mounted on one side of the first support roller assembly 5 via a track. It includes components such as a laser generator, an optical path system, and a focusing lens group. The track traveled by the laser rust removal device 6 is aligned with the length direction of the first support roller assembly 5, so that the laser rust removal device 6 can travel back and forth along the length direction of the circular tube to perform laser rust removal.

[0039] In addition, the laser generator produces a high-energy laser, which is transmitted through the optical path system and focused by the focusing lens group to accurately irradiate the rusted areas on the surface of the round tube. The high energy of the laser instantly vaporizes the rust, achieving an efficient and non-contact rust removal operation.

[0040] Moreover, the laser rust removal device 6 can move along the track to adapt to round pipes of different lengths, ensuring the comprehensiveness and uniformity of the rust removal process.

[0041] Please see Figure 2 In this embodiment, the overhead crane mechanism 4 is movably mounted above the first support roller assembly 5 via the overhead rail 3. It is mainly used to transfer the rust-removed round pipe to the painting station. The overhead rail 3 is supported by a steel structure on the inner side of the processing room 1. Its span covers the first support roller assembly 5 and the laser rust removal device 6, so that the overhead crane mechanism 4 can pick up the round pipe for automated transfer.

[0042] In this embodiment, the overhead crane mechanism 4 includes a three-axis displacement mechanism and a pipe bracket 47.

[0043] Please see Figure 3-4 The three-axis displacement mechanism includes a moving platform 42, a transverse movement mechanism, and an adjustment mechanism. The bottom of the moving platform 42 is equipped with a moving seat 41, which is slidably connected to the ceiling track 3.

[0044] The transverse movement mechanism is an important component of the overhead crane mechanism 4. It includes a transverse movement motor 48 and two transmission rods 49. The transverse movement mechanism is connected to the moving platform 42. The two transmission rods 49 are simultaneously connected to the output end of the transverse movement motor 48 via couplings. A rack 31 is provided on the overhead rail 3, and transmission wheels 491 are provided at the ends of the transmission rods 49, which mesh with the rack 31. When the transverse movement motor 48 is started, it drives the two transmission rods 49 to rotate, which in turn drives the transmission wheels 491 at both ends to roll on the rack 31, enabling the moving platform 42 to move stably and quickly along the overhead rail 3, realizing the transfer of the circular tube between different work positions.

[0045] The adjustment mechanism includes a horizontal frame 43, an adjustment motor assembly 45, and a lifting arm 46. The adjustment motor assembly 45 is mounted on the horizontal frame 43 and includes a horizontal adjustment motor 451 and a lifting adjustment motor 452. A moving platform 42 is equipped with a moving platform guide rail 421. The output end of the horizontal adjustment motor 451 is driven to the moving platform guide rail 421 via a transmission component, driving the horizontal frame 43 to move horizontally relative to the moving platform 42. The lifting arm 46 is vertically slidably connected to the horizontal frame 43. A lifting arm guide rail 461 is located on the front of the lifting arm 46. The lifting adjustment motor 452 is driven to the lifting arm guide rail 461 via a lifting gear 4521, driving the lifting arm 46 to move vertically up and down relative to the moving platform 42. Through precise control of the adjustment mechanism, the lifting arm 46 can be flexibly adjusted to accommodate round tubes of different heights and specifications, ensuring stable gripping and transfer of the round tubes.

[0046] In an optional embodiment, the transmission component is selected as a gear, whose shaft is connected to the output end of the horizontal adjustment motor 451, is driven to rotate by the horizontal adjustment motor 451, and can mesh with the moving table guide rail 421 so that the horizontal frame 43 can move horizontally along the length direction of the moving table 42.

[0047] In an optional embodiment, a translational slide rail 44 is provided between the horizontal frame 43 and the moving platform 42. The horizontal frame 43 is connected to the slider of the translational slide rail 44, and the moving platform 42 is connected to the track of the translational slide rail 44. This design enables the horizontal frame 43 to move horizontally smoothly and accurately under the drive of the horizontal adjustment motor 451, improving the operational stability and positioning accuracy of the overhead crane mechanism 4.

[0048] To facilitate the picking up of round tubes, the tube holder 47 has a recessed groove on its upper part for inserting the round tube. The design of the tube holder 47 can closely fit the outer circumference of the round tube, providing stable support and reliable fixation when picking up and transferring the round tube, preventing the round tube from sliding or shaking during movement, and ensuring the safety and stability of the operation.

[0049] Please see Figure 6 In this embodiment, the painting mechanism 8 is located on one side of the crane mechanism 4, and includes a spray gun 82 and a movable frame 81. The spray gun 82 is connected to the movable frame 81, and the movable frame 81 is movably installed in the processing room 1.

[0050] In an optional embodiment, the processing room 1 is provided with a paint spraying track 11, on which a paint spraying guide rail 111 is provided, and a movable frame 81 is slidably connected to the paint spraying track 11. The movable frame 81 is provided with a paint spraying motor 83, which is connected to the paint spraying guide rail 111 through a transmission component, and is used to drive the movable frame 81 to move on the paint spraying track 11.

[0051] Driven by the paint spraying motor 83, the moving frame 81 drives the spray gun 82 to move along the paint spraying guide rail 111, thereby achieving uniform paint spraying on the surface of the round tube from all directions.

[0052] It should be noted that a paint supply mechanism 9 is provided on one side of the painting mechanism 8. The paint supply mechanism 9 includes a roller frame 91 and a paint bucket 92. The roller frame 91 is connected to the movable frame 81. The paint bucket 92 is placed on the roller frame 91, and the paint bucket 92 is connected to the spray gun 82 through a pump for supplying paint.

[0053] The paint supply mechanism 9 can move together with the moving frame 81 to ensure that the spray gun 82 always has a sufficient supply of paint during the painting process. At the same time, the design of the roller frame 91 facilitates the installation, replacement and maintenance of the paint bucket 92.

[0054] To improve the accuracy of the movement of the paint supply mechanism 9, a roller guide rail 12 is also provided in the processing room 1, and the roller frame 91 is rotatably connected to the roller guide rail 12.

[0055] Example 2: Please refer to Figure 5 The transfer component 7 is movably disposed between the overhead crane mechanism 4 and the painting mechanism 8 via the ground rail 10. When it moves to the painting mechanism 8, it can serve as a painting station. It includes a moving mechanism and a second support roller assembly. The second support roller assembly and the first support roller assembly 5 have the same structure, both including at least two support members 74, at least two rollers 75 and a drive member 76.

[0056] The moving mechanism includes a moving carriage 71 and a transfer motor 73. The moving carriage 71 is the basic load-bearing structure of the transfer assembly 7. Multiple wheels 72 are mounted on the bottom of the moving carriage 71, and these wheels are rolled along the ground rail 10 to allow the transfer assembly 7 to move smoothly on the ground rail 10. The output of the transfer motor 73 is connected to the ground rail 10 via a transmission component, and is used to control the movement of the transfer assembly 7 between the overhead crane mechanism 4 and the painting mechanism 8. The transfer motor 73 can precisely control the position of the moving carriage 71, ensuring the smooth transfer and accurate docking of the round tube between each workstation.

[0057] In an optional embodiment, the transmission component is a gear, which is connected to the output shaft of the transfer motor 73 and meshes with the ground rail 10 to drive the transfer assembly 7.

[0058] In this embodiment, the support member 74 is movably arranged along the surface of the moving vehicle 71, and each roller 75 is rotatably arranged at the end of the support member 74. A gap is formed between two adjacent rollers 75 for placing the round tube. The driving member 76 is axially connected to a roller 75. The driving member 76 drives the roller 75 to rotate. The roller 75 drives the round tube to rotate through friction, so that the round tube can be evenly coated with paint during the painting process, thereby improving the painting quality.

[0059] The support member 74 is also equipped with a transmission member 77, which is connected to the drive member 76 and a roller 75 to transmit the traction force of the drive member 76 to drive the roller 75 to rotate. The design of the transmission member 77 enables the power of the drive member 76 to be effectively transmitted to the roller 75, ensuring the stable rotation of the roller 75, thereby achieving smooth rotation and painting of the round tube.

[0060] The AGV transporter 14 is an automated guided vehicle used to transport the cylindrical tubes to be processed from the outside to the first support roller assembly 5. The AGV transporter 14 has a high degree of automation and flexibility, and can automatically travel according to a preset path and task, realizing efficient and accurate transportation of cylindrical tubes, reducing the labor intensity and time cost of manual handling.

[0061] Temporary storage rack 13 is placed in a suitable location in processing room 1 to temporarily store round pipes that have undergone rust removal and painting. The temporary storage rack 13 has a reasonable structural design, which can stably support the round pipes, while facilitating the loading, unloading, and subsequent transportation of the round pipes.

[0062] In actual operation, the round tube to be processed is first transported to the first support roller assembly 5 by the AGV transport vehicle 14. After the round tube is placed on the rolling support roller of the first support roller assembly 5, the laser rust removal device 6 moves along the track to the side of the round tube and starts. The high-energy laser generated by the laser removes rust by scanning the surface of the round tube point by point or line by line. During the laser rust removal process, the round tube can slowly roll on the rolling support roller to ensure that the surface rust is completely removed.

[0063] After rust removal is completed, the horizontal movement motor 48 of the overhead crane mechanism 4 is started, driving the transmission rod 49 to move the overhead crane mechanism 4 along the overhead rail 3 to above the first support roller assembly 5. The horizontal adjustment motor 451 and the lifting adjustment motor 452 of the adjustment mechanism respectively drive the horizontal frame 43 and the lifting arm 46 to adjust to the appropriate position, so that the pipe support 47 at the bottom of the lifting arm 46 is accurately aligned and lifted to pick up the round pipe. After the pipe is picked up, the overhead crane mechanism 4 moves along the overhead rail 3 to transfer the round pipe to the moving cart 71 of the transfer assembly 7.

[0064] Driven by the transfer motor 73, the mobile cart 71 moves to the painting station. The round tube is placed between the rollers 75 of the transfer assembly 7. The drive component 76 drives the rollers 75 to rotate. The rollers 75 rotate the round tube through friction. At the same time, the painting mobile motor 83 of the painting mechanism 8 starts, driving the mobile frame 81 to move along the painting mobile track 11. During the movement, the spray gun 82 sprays paint evenly on the surface of the rotating round tube. The paint supply mechanism 9 continuously supplies paint to the spray gun 82 to ensure the continuity and quality of the painting operation.

[0065] After the painting is completed, the transfer component 7 transfers the round tube to the temporary storage rack 13 for temporary storage, awaiting subsequent packaging and transportation. The entire process is highly automated, with each component working together to achieve efficient and precise rust removal and painting of the round tube surface, greatly improving production efficiency and product quality, reducing labor costs and labor intensity, and yielding significant economic and social benefits.

It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.
