Description

Technical Field

[0001] This utility model relates to the field of welding machine auxiliary devices with automatic alignment of steel strips, specifically a magnetic conveyor belt alignment device for the inlet and outlet of a welding machine in a strip steel production line. Background Technology

[0002] In order to ensure the welding accuracy of thin steel plates during the welding production process in steel mills, it is usually necessary to center the head and tail of the steel strip to prevent the steel strip from shifting during the welding process. Also, because the thin steel plate is too light, it cannot be fed into the clamp of the welding machine along with the conveyor belt.

[0003] Traditional welding machines often require manual intervention to center the steel strip during the welding process. This is not only inefficient, affecting the overall production efficiency of the unit, but also cannot guarantee the centering accuracy, leading to frequent welding failures and seriously affecting the production of the entire unit. Therefore, a magnetic conveyor belt centering device for the inlet and outlet of the strip steel production line welding machine is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a magnetic conveyor belt alignment device for the inlet and outlet of a strip steel production line welding machine, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetic conveyor belt alignment device for the inlet and outlet of a strip steel production line welding machine, including a worktable.

[0006] The bottom of the workbench is fixedly connected to several support legs, and an L-shaped bracket is fixedly connected to the outside of the support legs. A top plate is fixedly connected to the top of the L-shaped bracket, and a first support plate is welded to the top of the top plate. An industrial camera CCD is bolted to the top of the first support plate.

[0007] Furthermore, a first servo motor is fixedly connected to the left side of the worktable, and a centering screw is fixedly connected to the output end of the first servo motor. A ball nut seat is threadedly connected to the centering screw.

[0008] Furthermore, linear slide rails are fixedly connected to the front and rear top ends of the worktable, a slider is slidably connected to the middle of the linear slide rails, and a second support plate is fixedly connected to the top end of the slider.

[0009] Furthermore, the front and rear ends of the second support plate are bolted to the first connecting plate, and the top end of the first connecting plate is bolted to the centering base, the top end of the centering base being provided with a moving groove.

[0010] Furthermore, a roller is provided in the middle of the moving groove, and a centering platform is fixedly connected to the top of the roller by a retainer.

[0011] Furthermore, an electric push rod is fixedly connected to the middle of the centering base, and a support rod is bolted to one end of the electric push rod.

[0012] Furthermore, a reduction motor is fixedly connected to the left side of the centering platform. The reduction motor is rotatably connected to a magnetic belt via a transmission shaft, and an electromagnet is attracted to the bottom end of the magnetic belt.

[0013] Furthermore, a third support plate is fixedly connected to the upper rear left and right sides of the centering platform, and a cylinder is fixedly connected to the top of the third support plate. The cylinder is fixedly connected to a clamping roller through a piston rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0024] Please see Figure 1-3This utility model provides a technical solution for a magnetic conveyor belt alignment device for the inlet and outlet of a strip steel production line welding machine: The magnetic conveyor belt alignment device for the inlet and outlet of a strip steel production line welding machine includes a workbench 12. Several support legs 13 are fixedly connected to the bottom of the workbench 12. An L-shaped bracket 14 is fixedly connected to the outer side of the support legs 13. A top plate 15 is fixedly connected to the top of the L-shaped bracket 14. A first support plate 16 is welded to the top of the top plate 15. An industrial camera CCD 17 is bolted to the top of the first support plate 16. By setting up the industrial camera CCD 17, the support legs 13, and the L-shaped bracket 14, a stable frame is formed. The installation position of the industrial camera can cover the strip steel conveying area, meeting the alignment monitoring requirements. A first servo motor 10 is fixedly connected to the left side of the workbench 12. By setting up the first servo motor 10, an alignment screw 11, and a ball nut seat 18, the servo motor... The servo motor drives the lead screw and nut pair, which can precisely control the horizontal displacement of the centering platform 5 to meet the fine adjustment requirements of the strip position. By setting the linear slide rail 19, slider 20, and second support plate 21, the second support plate 21 connects the first connecting plate 22, centering base 6, moving groove 23, roller 24 and centering platform 5. The structure of roller 24 reduces the moving resistance of the platform, the moving groove 23 limits the direction of movement and ensures the linear accuracy of the centering process, and the linear slide rail 19 system provides low friction guidance to ensure the smooth movement of the centering platform 5 and reduce mechanical vibration interference. The output end of the first servo motor 10 is fixedly connected to the centering lead screw 11, and the centering lead screw 11 is threadedly connected to the ball nut seat 18. The front and rear top ends of the worktable 12 are fixedly connected to the linear slide rail 19, the middle of the linear slide rail 19 is slidably connected to the slider 20, and the top end of the slider 20 is fixedly connected to the second support plate 21.

[0025] The front and rear ends of the second support plate 21 are bolted to the first connecting plate 22. The top of the first connecting plate 22 is bolted to the centering base 6. The top of the centering base 6 has a moving groove 23. A roller 24 is set in the middle of the moving groove 23. The top of the roller 24 is fixedly connected to the centering platform 5 through a retainer. An electric push rod 9 is fixedly connected to the middle of the centering base 6. By setting the electric push rod 9, the reduction motor 4, the magnetic belt 2, the electromagnet 3, the cylinder 7, and the pinch roller 8, the magnetic belt 2 and the electromagnet 3 cooperate to realize the non-slip conveying of the strip steel, which is suitable for thin gauges. The strip steel is provided with bidirectional clamping force by a cylinder 7 driving a pinch roller 8 to prevent the strip steel from deviating. An electric push rod 9 assists in fine-tuning the platform tilt angle to adapt to different working conditions. One end of the electric push rod 9 is bolted to a support rod 25. A reduction motor 4 is fixedly connected to the left side of the centering platform 5. The reduction motor 4 is rotatably connected to a magnetic belt 2 through a transmission shaft. An electromagnet 3 is attracted to the bottom end of the magnetic belt 2. A third support plate 26 is fixedly connected to both the left and right sides of the upper rear end of the centering platform 5. A cylinder 7 is fixedly connected to the top of the third support plate 26. The cylinder 7 is fixedly connected to the pinch roller 8 through a piston rod.

[0026] In use, when the strip enters the magnetic belt 2, the electromagnet 3 is energized to generate magnetic force, firmly attracting the strip onto the magnetic belt 2. The reduction motor 4 drives the magnetic belt 2 to rotate, feeding the strip into the clamp. After the strip enters the clamp, the reduction motor 4 stops, and the industrial camera CCD17 begins to detect the deviation of the strip. Based on the deviation, the system drives the electric push rod 9 to rotate the centering platform 5, keeping the strip horizontal with the direction of travel. At this time, the cylinder 7 pushes the clamping roller 8 to tightly clamp the strip, preventing it from shifting. The electromagnet 3 is then de-energized, allowing the strip to... No longer adhering to the magnetic belt, the electric push rod 9 will drive the centering platform 5 to rotate back to the initial position. Because the electromagnet 3 is now de-energized and the clamping roller 8 has pressed the strip steel, the strip steel will not move with the rotation of the centering platform 5. After the centering platform 5 returns to its original position, the electromagnet 3 will be energized again to make the strip steel adhere to the magnetic belt 2. The cylinder 7 will drive the clamping roller 8 to release the strip steel. The industrial camera CCD 17 will detect the position of the strip steel again. The system will calculate the difference between the left and right sides and control the servo motor 10 to drive the centering screw 11 to push the centering base 6 to move and complete the final centering step.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
