Description

Technical Field

[0001] This invention relates to the field of steel rolling equipment technology, and in particular to a steel coil coating system. Background Technology

[0002] Annealing of cold-rolled steel sheets (in coil form) is the most important heat treatment process in the production of cold-rolled strip steel. To prevent oxidation at high temperatures during heat treatment, the ends of the steel coils need to be coated with a magnesium oxide solution before entering the ring furnace, and a fan-shaped protective plate is placed over the top end. Currently, production line workers apply the magnesium oxide coating to both ends of the coils, requiring an overhead crane to lift the coils during the coating process on the bottom end. Because the steel coils arrive at high temperatures (typically ≥45℃) from the production line during the magnesium oxide coating process, workers face a risk of burns. Furthermore, the coating operation generates a large amount of dust, negatively impacting the health of workers in the work area. The current production process involves high risks and heavy workloads due to manual operation. Therefore, there is an urgent need for a steel coil coating system that can automatically complete the coating process, reducing the risks and labor burden of manual operation.

Furthermore, in one or more embodiments, the particular features, structures, or characteristics can be combined in any suitable manner, as will be apparent to those skilled in the art from this disclosure.

[0030] The specific structure of the steel coil coating system 10 in the embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0031] Figure 1 This is a schematic diagram showing the distribution of the steel coil coating system 10 in an embodiment of this application. Figure 1 As shown, the steel coil coating system 10 in this embodiment includes a robot 100 and a coating preparation device 200, a first storage platform 300, a first coating platform 400, a second storage platform 500 and a second coating platform 600 arranged around the robot 100.

[0032] The robot 100 can be an industrial six-axis robot. The robot 100 has a robotic arm 110, with a quick-change head mounted on its end flange. The robotic arm 110 can quickly install and change painting tools and suction cup tools, enabling painting and material handling operations. The robot 100 also has a ground rail 120 along which the robotic arm 110 moves. Its position can be adjusted according to the needs of painting and material handling operations, allowing it to move to the appropriate equipment for painting, material handling, and paint application.

[0033] A bracket 700 is also provided on one side of the end of the ground rail 120 for storing painting tools and suction cup tools. The robotic arm 110 can place the painting tools or suction cup tools installed at its end on the bracket 700, or retrieve the painting tools or suction cup tools from the bracket 700 as needed to complete painting and handling operations.

[0034] The paint preparation device 200 is used to prepare paint, which can be magnesium oxide paint. The robot 100 can control a brushing tool to pick up the paint in the paint preparation device 200. The paint preparation device 200 is a mixer with its opening facing upwards, allowing the robotic arm 110 to control the brushing tool to reach into the mixer and pick up the paint. The mixer also has an inlet pipe and a drain pipe. The inlet pipe supplies water for mixing the paint and for cleaning, while the drain pipe discharges waste liquid. Specifically, the inlet pipe can meter the water added to the mixer to ensure accurate paint mixing. The paint preparation device 200 has an automatic cleaning function; water supplied by the inlet pipe can rinse the inside of the mixer, and the waste liquid generated during cleaning can be discharged through a valve at the bottom into the drain pipe.

[0035] The first storage platform 300 is used to place the protective plate before coating. The protective plate is adapted to the shape of the end face of the steel coil and can be set as a circular ring or a semi-circular ring. The robot 100 is equipped with a suction cup tool to pick up the protective plate from the first storage platform 300 and place the protective plate on the second coating platform 600 for coating. In this way, the first storage platform 300 can supply the protective plate to the second coating platform 600, thereby ensuring the production rhythm and improving production efficiency.

[0036] The second coating platform 600 is located adjacent to the first storage platform 300. After the robot 100 is equipped with coating tools, it can coat the protective plate on the second coating platform 600. The second coating platform 600 can also heat the protective plate, thereby accelerating the drying and solidification of the coating on the protective plate.

[0037] The second storage platform 500 is used to place the coated protective plates. The second storage platform 500 and the second coating platform 600 are positioned correspondingly on opposite sides of the ground rail 120. The robot 100, equipped with suction cups, adsorbs the coated protective plates from the second coating platform 600 and places them onto the second storage platform 500. The second storage platform 500 is located adjacent to the first coating platform 400, facilitating the robot 100's use of suction cups to adsorb the protective plates from the second storage platform 500 and place them onto the upper surface of the steel coils on the first coating platform 400. Thus, the second storage platform 500 can store the coated protective plates from the second coating platform 600 and provide them to the first coating platform 400, protecting the upper surface of the steel coils. This ensures production rhythm and improves production efficiency.

[0038] The first coating platform 400 includes a saddle and a lifting device. The steel coil is placed on the saddle, with its axis vertically aligned. The lifting device can be an electromagnetic crane formed by an overhead crane and an electromagnetic chuck, or other suitable lifting equipment; there are no limitations on this. The lifting device is used to lift the steel coil so that the robot 100 can control the coating tool to coat the lower surface of the steel coil.

[0039] like Figure 1 The first coating platform 400 shown also includes a first detection device 800, which is used to detect the position, outer diameter, and height information of the steel coil on the saddle. The lifting device can adjust the position of the steel coil according to the position information so that the robot 100 can coat the steel coil. In addition, the robot 100 can also adjust the coating trajectory according to the position, outer diameter, and height information of the steel coil to improve the coating effect.

[0040] Furthermore, the steel coil coating system 10 in this application also includes a second detection device 900. The second detection device 900 can be a vision inspection device, positioned facing the first coating platform 400 and the second coating platform 600, for detecting the coating effect. Specifically, the second detection device 900 can be positioned at positions corresponding to the first coating platform 400 and the second coating platform 600, or it can be as follows: Figure 1 The coating is mounted on the robotic arm 110 of the robot 100, as shown, but this is not a limitation. The second detection device 900 can detect the coating effect so that the robot 100 can coat the protective plate and steel coil according to the detection results, thereby improving the coating effect and avoiding problems such as uneven coating and missed areas.

[0041] In summary, when using the steel coil coating system 10 in this embodiment to coat steel coils, a certain amount of water required for solution preparation is first injected into the coating preparation device 200. Then, the weighed and quantitatively measured magnesium oxide is poured into the preparation device. The mixture of magnesium oxide and water is stirred by the coating preparation device 200 to complete the preparation of the magnesium oxide coating. After the mixing is completed, the coating preparation device 200 is kept in a stirring state to prevent the magnesium oxide coating from settling.

[0042] The lifting device hoists the steel coil onto the saddle of the first coating platform 400. The first detection device 800 checks whether the position of the steel coil meets the coating requirements and uses indicator lights to alert the crane operator and other control personnel to confirm the correct position. Once the coating requirements are met, the operation stops. The first detection device 800 detects the outer diameter, height, and position information of the steel coil, accurately locating the end face of the steel coil to be coated, and calculates and adjusts the coating trajectory of the robot 100 based on the detected position. The robot 100 automatically picks up the coating tool, dips it in magnesium oxide coating, and moves it to the upper and lower end faces of the steel coil. It coats the end faces of the steel coil according to the process requirements, and the second detection device 900 judges the coating effect to avoid problems such as uneven coating or missed areas. After coating is completed, the robot 100 returns to its original position, indicating this via indicator lights, and transmits a signal to the crane. The crane then unlocks and lifts the steel coil away from the coating station.

[0043] Robot 100 uses a quick-change head to pick up a suction cup tool, moves to the first storage platform 300, and picks up the protective plate, placing it on the second coating platform 600. Robot 100 then changes to a coating tool, moves to the paint preparation device 200 to pick up paint, and applies it to the protective plate on the second coating platform 600. The second detection device 900 assesses the coating effect to prevent uneven coating or missed areas. After coating, the second coating platform 600 activates its heating function to dry the protective plate. Robot 100 then uses a suction cup tool to pick up the dried protective plate and place it on the second storage platform 500. Robot 100 repeats the above actions until all protective plates are coated, then lowers the coating tool and suction cup tool and returns to its original position.

[0044] Note that the above are merely preferred embodiments and the technical principles employed in this application. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
