Description

Technical Field

[0001] This utility model relates to steel surface treatment equipment, and more particularly to a rust removal device for structural steel. Background Technology

[0002] In the steel production industry, quality control of steel is of paramount importance. For steel that has been stored for an extended period, rust removal is an indispensable process. This is primarily based on several considerations: Firstly, it improves the surface quality of the steel, preventing adverse effects on its appearance caused by prolonged rust buildup, and also preventing rust from impairing the overall performance of the steel; secondly, it effectively prevents further corrosion of the steel, extending its service life; and thirdly, it meets the factory requirements for standard steel products. The industry has strict regulations on the surface condition of steel, and rust removal is a necessary step to ensure that products meet these standards.

[0003] Currently, the most common rust removal methods used in steel mills are mechanical rust removal, chemical rust removal, and laser rust removal. However, each of these existing technologies has significant drawbacks. Mechanical rust removal not only damages the steel surface and reduces its quality, but also requires extremely high labor intensity and has very low efficiency, making it difficult to meet the needs of large-scale production. While chemical rust removal can achieve rust removal to some extent, it faces severe environmental pressures, as the chemical agents used can easily pollute the environment. At the same time, chemical agents pose significant health risks to operators, requiring strict protective measures, which undoubtedly increases production costs and operational complexity. Although laser rust removal has certain advantages, it still relies on manual operation, preventing it from fully realizing its high efficiency and convenience. Summary of the Invention

[0009] Furthermore, the roller frame adopts a circular frame with grooves along its circumference, and the chain is embedded in the grooves.

[0010] Furthermore, when the roller frame rotates relative to the corresponding support base, the outer wall of the roller frame comes into contact with the corresponding support wheel. The support wheel is used to support the roller frame and utilizes rolling friction to reduce wear.

[0011] Furthermore, the roller frame has a square hole, one end of the upper roller and one end of the lower roller extend into the square hole, and the two ends of the lower roller are fixed to the square hole.

Detailed Implementation

[0025] The robotic arm 103, with six degrees of freedom, can move on the ground rail 101, enabling it to remove rust from multiple surfaces of the steel profile 106. A 3D vision system 104 identifies the position and shape of the steel profile 106, guiding the robotic arm and laser 105 to precisely remove rust from the steel surface. The laser 105 is mounted at the end of the robotic arm (103) and moves with it to remove rust from different parts of the steel profile. Specifically, the robotic arm 103 is mounted on the ground rail 101 via a robot base 102 at its bottom. The robot base 102 is slidably connected to the ground rail 101 via a slider, and the ground rail 101 guides the robotic arm 103 along the conveyor line 107. The robotic arm 103 moves from one end to the other via the ground rail 101. The 3D vision system 104 scans the steel profile 106 on the conveyor line 107 to establish the digital model and position information of the steel profile. The robotic arm 103 activates the laser 105 to remove rust from the predetermined surface of the steel profile. At the same time, the robotic arm 103 moves along the ground rail 101 until the rust removal work on one side of the steel profile is completed.

[0026] The steel section turning machine 2 includes at least two support bases 201. Each support base 201 is equipped with a roller frame 206 on its top. Two roller lines are arranged side by side between two adjacent roller frames 206: an upper roller line 209 and a lower roller line 208. When the steel section 106 enters the steel section turning machine 2 from the conveyor line 107, the steel section 106 is sandwiched between the upper roller line 209 and the lower roller line 208. The support base 201 is equipped with a drive motor 203 and a sprocket 204, and the roller frame 206 is equipped with a chain 205. The steel section turning machine 2 rotates the roller frame 206 180 degrees by the drive motor 203 via the sprocket 204 and the chain 205 to achieve the turning of the steel section 106.

[0027] Preferably, the support base 201 is provided with at least two support wheels 202 and sprockets 204, wherein both the support wheels 202 and sprockets 204 are rotatably connected to the support base 201; the roller frame 206 is connected to the corresponding sprocket 204 of the support base 201 via a chain 205; and the sprocket 204 is mounted on the drive shaft of the drive motor 203, which is mounted on the outer wall of the support base 201; the rotation of the drive motor 203 drives the sprocket 204 to rotate, which in turn drives the roller frame 206 to rotate via the chain 205. That is, the drive motor 203 is connected to the sprocket 204 via the drive shaft, and the sprocket 204 is connected to the roller frame 206 via the chain 205, forming a power transmission path.

[0028] Preferably, the roller frame 206 is a circular frame with grooves 207 along its circumference, and the chain 205 is embedded in the grooves 207. The roller frame 206 has a square hole 212. One end of the upper roller 209 and the lower roller 208 extends into the square hole 212, and both ends of the lower roller 208 are fixedly connected to the square hole 212. The top of the upper roller 209 is connected to the inner wall of the square hole via a clamping cylinder 211. The cylinder seat of the clamping cylinder 211 is fixed to the square hole 212, and the extension rod of the clamping cylinder 211 extends downward and connects to the upper roller 209, ensuring that the upper roller can stably clamp the steel section, thereby achieving the fixing and release of the steel section 106. Furthermore, stop posts 210 are provided on both sides of the lower roller 208 to limit the position of the steel section 106. Finally, the steel turning machine 2 drives the upper roller line 209 to press the steel 106 downward through the pressing cylinder 211, and drives the roller frame 206 to rotate 180° to realize the turning of the steel.

[0029] Preferably, when the roller frame 206 rotates relative to the corresponding support base 201, the outer wall of the roller frame 206 contacts the corresponding support wheel 202. The support wheel 202 is used to support the roller frame 206 and uses rolling friction to reduce wear.

[0030] Work process:

[0031] 1. For steel sections that require rust removal, the steel sections are manually hoisted onto the conveyor line using an overhead crane, and the loading is confirmed manually.

[0032] 2. At this point, the robotic arm is activated. The robotic arm, carrying a 3D camera, aligns with the conveyor line. It moves along the ground rail from one end to the other. The 3D vision system scans the steel sections on the conveyor line, establishing a digital model (dimensional outline) and positional information of the steel sections. After scanning and determining the position of the steel sections, the robotic arm starts from the other end of the ground rail and activates the laser to remove rust from a designated surface of the steel section. During the rust removal process, the robotic arm simultaneously moves from one end of the ground rail to the other, completing the rust removal work on one side of the steel section. This process can be repeated to remove rust from other surfaces of the steel sections accessible to the robotic arm.

[0033] 3. After the rust removal work on the other accessible surfaces of the steel profile has been completed, if rust removal is required on other surfaces, the steel profile must be flipped over before rust removal can continue.

[0034] 4. At this point, start the conveyor line to transport the steel profile into the steel profile turning machine. Once the entire steel profile has entered the machine, the clamping cylinder activates, extending its rod to drive the upper roller conveyor downwards until it contacts and presses against the upper surface of the steel profile. Then, start the drive motor, which drives the chain via the sprocket. The chain rotates the roller frame 180°, completing the steel profile turning process.

[0035] 5. After the steel section is flipped, the upper roller line moves to convey the steel section out of the steel section flipping machine and onto the conveyor line. At this time, the robot with 3D vision repeatedly scans the steel section to confirm the model and position, and then removes rust from the unrusted surface.

[0036] This utility model steel rust removal device uses a robotic arm equipped with 3D vision to identify the position, shape and size of the steel section. Then, based on the vision recognition, the laser carried by the robotic arm is guided to clean the rust stains on the surface of the steel section. No human intervention is required in the entire rust removal process. The robotic arm itself has 6 degrees of freedom and can perform rust removal work on multiple sides of the steel section.

[0037] This utility model of steel rust removal device is also equipped with a steel turning machine to realize the automated turning of steel. After manual feeding, the rust removal work on all surfaces of the steel can be completed automatically, which greatly improves work efficiency and reduces manual labor.

[0038] It is understood that the above specific description of this utility model is only used to illustrate this utility model and is not limited to the technical solutions described in the embodiments of this utility model. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
