Description

Technical Field

[0001] This utility model relates to the field of steel coil transportation technology, and in particular to a magnetic suction manipulator for strip transfer. Background Technology

[0002] Cold-rolled steel strip is made from hot-rolled coils as raw materials and rolled at room temperature below the recrystallization temperature. It includes plates and coils, and many steel mills in China can produce it. Steel strips delivered in sheets are called steel plates, also known as box plates or flat plates, while steel strips delivered in coils are called steel strips, also known as coil plates. Cold-rolled ultra-thin steel strips use the same raw materials, but the process is more complex.

[0003] In steel mills, the most common product is steel plate. Due to the different shapes of finished products, steel strips need to be cut into steel plates of various sizes. Since cold-rolled ultra-thin steel strips are relatively thin, the traditional method of transportation is to stack the strips and bundle them together for transport to other processes or loading. Because there are not many tools for moving the strips, stacking not only damages the strips but also results in uneven stacking. Therefore, when transporting the strips after bundling, it is easy to cause scratches on the surface of the strips or abnormal deformation. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a magnetic suction robot for strip transfer, which can effectively adsorb the surface of the strip during the transfer process, thereby avoiding damage to the strip when stacking it, and ensuring that the strip is stacked neatly and will not be damaged by compression after bundling.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A magnetic suction robot for conveying strips, including

[0007] Industrial six-axis robot;

[0008] The magnetic suction mechanism includes a connecting frame, an extension frame, and electromagnetic chucks. The connecting frame has connecting holes that are connected to the shaft of a rotary motor at the end of the industrial six-axis robot. The extension frame is composed of longitudinal and transverse bars arranged in a crisscross pattern. The middle part of the extension frame is fixedly connected to the end face of the connecting frame away from the end face of the industrial six-axis robot. Several electromagnetic chucks are installed on the longitudinal and transverse bars, with the electromagnetic chucks facing away from the connecting frame.

[0009] Optionally, the extension frame includes three vertical bars and three horizontal bars, which are arranged in an alternating pattern to form a grid.

[0010] Optionally, each joint of the crossbar and the vertical bar has a mounting hole, and an electromagnetic chuck is fixedly installed in each mounting hole.

[0011] Optionally, the connecting frame includes a rectangular connecting plate and four strength support rods. The four strength support rods are respectively connected to the four corners of the rectangular connecting plate, and the four strength support rods are respectively fixedly installed on the longitudinal and transverse rods in the middle of the extension frame.

[0012] Optionally, both the vertical and horizontal bars are hollow, and the connecting wires of the electromagnetic chuck are threaded inside the vertical and horizontal bars.

[0013] Optionally, the magnetic suction mechanism may also include a silicone sleeve, which is fixedly installed at the end of the electromagnetic chuck.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The application of this magnetic suction robot for strip and sheet transport enables safer and more efficient transport of cold-rolled steel sheets and ultra-thin steel strips. It utilizes a six-axis industrial robot to control the magnetic suction mechanism for precise operation. The connecting frame within the magnetic suction mechanism is tightly connected to the robot, ensuring accurate motion. The crisscrossing longitudinal bars on the extension frame and the electromagnetic chucks on the transverse bars can evenly attract strips and sheets of various sizes, making the delivery of cut steel sheets or the movement and stacking of cold-rolled ultra-thin steel strips precise and controllable. This avoids surface damage or deformation caused by uneven stacking and improper bundling in traditional transport methods, preventing scratches on the strip and sheet surface. This not only improves the protection of strip and sheet products during production but also significantly enhances production efficiency and product quality. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] Example 1

[0023] Combination Figures 1-3 As shown in the illustration, an embodiment of this utility model discloses a magnetic suction manipulator for strip and plate transport, comprising an industrial six-axis robot 1 and a magnetic suction mechanism 2. The magnetic suction mechanism 2 in this embodiment includes a connecting frame 3, an extension frame 4, and electromagnetic chucks 5. The connecting frame 3 has connecting holes that are connected to the shaft of a rotary motor at the end of the industrial six-axis robot 1. The extension frame 4 is composed of longitudinal bars 6 and transverse bars 7 arranged in a crisscross pattern, with the middle portion of the extension frame 4 fixedly connected to the end face of the connecting frame 3 facing away from the industrial six-axis robot 1. Several electromagnetic chucks 5 are installed on both the longitudinal bars 6 and transverse bars 7, with the electromagnetic chucks 5 facing away from the connecting frame 3. The application of this magnetic suction manipulator for strip and plate transport enables safer and more efficient transport of cold-rolled steel plates and ultra-thin steel strips. It uses an industrial six-axis robot 1 to control the magnetic suction mechanism 2 for precise operation. The connecting frame 3 in the magnetic suction mechanism 2 is tightly connected to the robot to ensure the accuracy of the movement. The electromagnetic chucks 5 on the crisscrossing vertical bars 6 and horizontal bars 7 on the extension frame 4 can evenly adsorb strips of various sizes, making the delivery of cut steel plates or the movement and stacking of cold-rolled ultra-thin steel strips precise and controllable. This avoids the surface damage or deformation caused by uneven stacking and improper bundling of strips in traditional transfer methods. The surface of the strips will not be scratched. This not only improves the protection of strip products during the production process, but also significantly improves production efficiency and product quality.

[0024] Furthermore, the extension frame 4 in this embodiment includes three vertical bars 6 and three horizontal bars 7. The three vertical bars 6 and three horizontal bars 7 are staggered and spliced ​​in a grid pattern, which enhances the stability and load-bearing capacity of the extension frame 4. Each horizontal bar 7 and vertical bar 6 has a mounting hole, and an electromagnetic chuck 5 is fixedly installed in each mounting hole. The combination of multiple electromagnetic chucks 5 can accommodate plates and strips of different sizes.

[0025] Furthermore, the connecting frame 3 in this embodiment includes a rectangular connecting plate 8 and four strength support rods 9. The four strength support rods 9 are respectively connected to the four corners of the rectangular connecting plate 8, and the four strength support rods 9 are respectively fixedly installed on the longitudinal rod 6 and the transverse rod 7 in the middle of the extension frame 4, which can improve the strength of the middle part of the longitudinal rod 6 and the transverse rod 7; and the four strength support rods 9 make the rectangular connecting plate 8 and the extension frame 4 form redundant space, which can provide installation space for the electromagnetic chuck 5.

[0026] Furthermore, in this embodiment, both the vertical rod 6 and the horizontal rod 7 are hollow, and the connecting wire of the electromagnetic chuck 5 is threaded inside the vertical rod 6 and the horizontal rod 7, which avoids the wiring of the electromagnetic chuck 5 affecting the rotation of the entire magnetic attraction mechanism 2 and extends its service life.

[0027] Furthermore, the magnetic suction mechanism 2 in this embodiment also includes a silicone sleeve 10, which is fixedly installed at the end of the electromagnetic chuck 5. This can prevent the electromagnetic chuck 5 from directly contacting the strip and prevent the electromagnetic chuck 5 from scratching the surface of the strip, thereby further improving the safety of strip transport.
