Description

Technical Field

[0001] This application relates to the field of steel coil machine technology, and more particularly to a labeling device for steel coil machines. Background Technology

[0002] Steel coils, also known as rolled steel, are steel products that have been hot-pressed or cold-pressed into coils. To facilitate storage, transportation, and various processing, labels are affixed to the outer surface of the steel coils during production to allow for a more intuitive observation of their specifications and detailed product information.

[0003] Currently, labeling of steel coils is mostly done manually. However, this method has the following drawbacks: on the one hand, it is slow and labor-intensive; on the other hand, when labeling, the entire adhesive surface of the label is usually in contact with the steel coil, which can easily cause air bubbles to form between the label and the surface of the steel coil, resulting in the label bulging and making subsequent identification work impossible.

[0032] Combination Figures 1-3 As shown, a labeling device for a steel coil machine includes a base 10, a robotic arm 11, a mounting platform 12, a telescopic cylinder 13, a vacuum suction cup 14, a mounting frame 15, rollers 17, and two sets of adjustment components 20. The base 10 is slidably mounted on an external frame. One end of the robotic arm 11 is mounted on the base 10, and the other end extends away from the base 10. The mounting platform 12 is horizontally fixed at the end of the robotic arm 11 away from the base 10. The telescopic cylinder 13 is fixedly mounted on the mounting platform 12, and the working end of the telescopic cylinder 13 extends radially along the robotic arm 11. The vacuum suction cup 14... The fixed end of the vacuum suction cup 14 is hinged to the side of the mounting platform 12 near the output end of the telescopic cylinder 13, and its free end is set at an angle to the plane of the mounting platform 12. The side of the vacuum suction cup 14 near the mounting platform 12 is hinged to the output end of the telescopic cylinder 13. The semi-enclosed mounting frame 15 is set at the free end of the vacuum suction cup 14, and the open area of ​​the mounting frame 15 faces the working area of ​​the vacuum suction cup 14. The roller 17 is rotatably set in the enclosed area of ​​the mounting frame 15. Two sets of adjustment components 20 are set on both sides of the roller 17 and are slidably connected to the inner wall of the enclosed area of ​​the mounting frame 15.

[0033] In the above solution, the robotic arm 11 and the sliding base 10 work together to automate the labeling operation, replacing manual operation and improving efficiency. The hinged design of the telescopic cylinder 13 and the vacuum suction cup 14 allows for adjustment of the suction cup angle, ensuring controllable contact angle between the label and the steel coil surface, and preventing air bubbles from remaining due to one-time full contact of the label. The semi-enclosed structure of the mounting frame 15, combined with the rollers 17, forms a guiding and pressing mechanism. After the label is adsorbed, the rolling pressure of the rollers 17 expels air, while the adjusting component 20 can adapt to different steel coil curvatures, ensuring uniform contact between the label and the curved surface. The linkage design of the vacuum suction cup 14 and the telescopic cylinder 13 achieves integrated action of label adsorption, angle adjustment, and pressure application, thereby preventing air bubbles from forming between the label and the steel coil.

[0034] The mounting bracket 15 has a U-shaped or C-shaped groove structure. The length direction of the groove of the mounting bracket 15 is consistent with the width direction of the vacuum suction cup 14. The mounting bracket 15 has a sliding groove 151 recessed on both sides of the groove wall along its length direction. The length direction of the sliding groove 151 is consistent with the height direction of the groove of the mounting bracket 15. The adjusting component 20 is slidably installed in the sliding groove 151 and is fixedly connected to the periphery of the roller 17.

[0035] In the above scheme, by designing the mounting frame 15 as a U-shaped or C-shaped groove structure, its semi-enclosed area forms a stable support space for the roller 17. The structural layout, with the groove length direction aligned with the width direction of the vacuum suction cup 14, ensures that the label is evenly stressed in the lateral width, avoiding air bubbles caused by uneven local pressure. The sliding grooves 151 on both sides of the groove wall extend along the groove height direction, allowing the adjustment component 20 to slide vertically. This allows for real-time adjustment of the roller 17 height according to the curvature of the steel coil surface, ensuring that the roller 17 always presses the label at the optimal angle. The structural design of the adjustment component 20 being fixedly connected to the periphery of the roller 17 ensures that the roller 17 moves synchronously with the mounting frame 15 during sliding, preventing label misalignment caused by roller 17 offset. The sliding fit between the sliding grooves 151 and the adjustment component 20 not only achieves the adjustability of the roller 17 position but also prevents shaking during adjustment through mechanical limiting, ensuring the stability of the label pressing process.

[0036] The adjusting assembly 20 includes a connecting rod 21, a slider 22, and an elastic element 23. The connecting rod 21 is fixedly installed in the corresponding groove 151, and the length direction of the connecting rod 21 is consistent with the length direction of the groove 151. The slider 22 is slidably disposed on the periphery of the connecting rod 21, and the periphery of the slider 22 is fixedly connected to the rotating shaft of the roller 17. The elastic element 23 is sleeved on the periphery of the connecting rod 21 and is located between the slider 22 and the bottom of the groove 151.

[0037] In the above scheme, the connecting rod 21 is fixed in the slide groove 151, providing a stable sliding path for the slider 22 along the direction of the slide groove 151, ensuring that the trajectory of the roller 17 is controllable when moving on the surface of the steel coil; the slider 22 is fixedly connected to the rotating shaft of the roller 17, so that the roller 17 can adjust its position synchronously with the sliding of the slider 22 to adapt to the unevenness of the steel coil surface; the elastic element 23 generates elastic force through compression deformation, pushing the slider 22 to move towards the bottom of the slide groove 151, thereby providing the roller 17 with a continuous and flexible clamping force, which not only avoids label deformation due to excessive pressure, but also eliminates the adhesion gap caused by insufficient pressure, thereby ensuring that the label is always in close contact with the surface of the steel coil during the rolling process, reducing air bubbles and bulging defects.

[0038] A baffle 16 is provided on the side of the vacuum suction cup 14 near the mounting bracket 15. The end of the baffle 16 away from the vacuum suction cup 14 extends from front to back and from top to bottom, and the bottom end of the baffle 16 is lower than the lowest point of the roller 17.

[0039] In the above scheme, the downward extension direction of the baffle 16 spatially matches the movement trajectory of the roller 17. The design of its bottom end being lower than the lowest point of the roller 17 allows the baffle 16 to contact the surface of the steel coil before the roller 17, pre-pressing the label before the roller 17 performs the pressing action. This structure not only avoids the local lifting of the label caused by the unevenness of the steel coil surface, but also forms a staged pressing process through the synergistic action of the baffle 16 and the roller 17. The pre-pressing of the baffle 16 can eliminate the initial gap between the label and the steel coil, and the subsequent pressing of the roller 17 achieves the final tight fit, thereby effectively solving the problem of label displacement or wrinkling caused by uneven force during dynamic labeling.

[0040] The baffle 16 has an overall arc-shaped structure, and the curved contour of the baffle 16 is consistent with the circumferential curvature of the roller 17.

[0041] In the above solution, by designing the baffle 16 as an arc-shaped structure with the same curvature as the circumferential surface of the roller 17, the baffle 16 can form a continuous contact surface with the roller 17. When the roller 17 applies pressure to the label, the curved contour of the baffle 16 can evenly distribute the contact pressure, avoiding label edge lifting or air bubbles in the middle area due to local stress concentration. At the same time, the matching design of the curved surfaces of the baffle 16 and the roller 17 ensures that the label remains flat during the rolling process, reducing label deformation caused by mechanical interference, thereby improving label flatness.

[0042] The peripheral surface of the vacuum suction cup 14 is coated with a nano anti-stick coating, and the working end face of the vacuum suction cup 14 is provided with a plurality of air holes 141, the cross-sectional profile of the plurality of air holes 141 being a tapered structure that is narrow at the inner end and wide at the outer end.

[0043] In the above solution, the adhesion between the vacuum suction cup 14 and the label is reduced by the nano anti-stick coating, ensuring that the label is completely removed from the suction cup surface when released, avoiding label tearing or residue caused by adhesion; the conical air hole 141 structure, with its cross-sectional design that is narrow at the inner end and wide at the outer end, allows the airflow to form a uniform adsorption force field that diffuses from the inside to the outside during the adsorption process, thereby reducing the local pressure concentration at the edge of the air hole 141 and preventing air bubbles from being generated due to uneven force when the label is bonded to the steel roll.

[0044] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, please refer to each other. Each embodiment focuses on describing the differences from other embodiments.

[0045] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
