Description

Technical Field

[0001] This invention belongs to the field of laser processing technology for hot-rolled coils, and particularly relates to a laser cutting device for processing hot-rolled coils. Background Technology

[0002] Hot-rolled coil, also known as hot-rolled steel coil, is a steel product made from slabs (mainly continuously cast slabs) as raw materials. The slabs are heated and rolled into strips by roughing and finishing mills, then cooled in laminar flow and coiled. As an indispensable basic material in modern industry, it is widely used in construction, automobiles, shipbuilding, machinery, home appliances, and energy pipelines, among other fields. This product features high strength, good ductility, and formability. Laser cutting is a processing method that uses a high-energy-density laser beam to cut non-metallic materials such as plexiglass, and is mainly used in the electronics and other industrial fields. This technology achieves cutting by heating the material with a CO2 laser (wavelength 10.6μm) or a femtosecond ultrafast laser, and features high precision (cut width 0.10-0.20mm).

[0003] In the processing of hot-rolled coils, laser cutting equipment is frequently used. During the cutting process, the hot-rolled material is cut according to the pre-set travel path of the laser cutting equipment. However, as the cutting path progresses and changes, the hot-rolled coil will shift to a certain position. This shift may be large or small. When the shift is greater than the reserved portion on the edge of the material, the product cut near the edge will be defective. Therefore, manual inspection and correction are required in real time, resulting in a large workload and making processing errors more likely. To avoid the above situation, a laser cutting equipment for hot-rolled coil processing is provided. Summary of the Invention

[0004] This invention provides a laser cutting device for hot-rolled coil processing, aiming to solve the problem that laser cutting equipment is frequently used in hot-rolled coil processing. During the cutting process, the hot-rolled coil material is cut according to the pre-set travel path of the laser cutting equipment. However, as the cutting path progresses and changes, the hot-rolled coil will shift to a certain position. This shift may be large or small. When the shift is larger than the reserved portion on the edge of the material, product defects will occur due to cutting near the edge. Therefore, manual inspection and correction are required in real time, resulting in a large workload and making processing errors more likely.

[0005] The present invention is implemented as follows: a laser cutting device for processing hot-rolled coil includes a frame: a laser cutting machine is fixedly connected to the inner wall of the frame, and a cutting baffle is fixedly connected to the outer wall of the laser cutting machine; a feeding monitoring mechanism is provided on the inner wall of the upper feed port of the frame; a feeding correction mechanism is provided on the inner wall of the upper feed port of the frame; an anti-tilting mechanism is provided on the inner wall of the upper feed port of the frame; and guide rollers are provided on the inner wall of the upper feed port of the frame.

The vertical support and the frame are fixedly connected by bolts. The position between the two feeding monitoring mechanisms can be adjusted according to the width of the hot-rolled coil, and then fixed on the frame by bolts.

[0006] Preferably, the monitoring component includes a vertical connecting shaft, an arc-shaped guide plate is fixedly connected to the outer wall of the vertical connecting shaft, an arc-shaped spring and an arc-shaped sleeve are fixedly connected to the inner side of the arc-shaped guide plate, and a circular pressure block is fixedly connected to one end of the arc-shaped spring and the arc-shaped sleeve. The circular pressure block is used in conjunction with a circular pressure sensor. The vertical connecting shaft is equipped with ball bearings at both its upper and lower ends, and the arc-shaped guide plate is rotatably connected to the ball bearings and the vertical seat through the vertical connecting shaft. During use, once the positions of the two feeding monitoring mechanisms are adjusted, the hot-rolled coil to be cut passes smoothly and precisely through the feeding channel between the two arc-shaped guide plates. When the position of the hot-rolled coil shifts during the conveying process, the hot-rolled coil will shift to one side, and the arc-shaped guide plate on one side will be subjected to force and rotate along the vertical connecting shaft. The circular pressure block on the arc-shaped spring on the back side of the arc-shaped guide plate will increase due to the pressure of the arc-shaped spring, causing the data of the circular pressure sensor to fluctuate.

In use, pull the adjustment shaft upward to lock the gear away from the circular gear groove, rotate the adjustment shaft to drive the adjustment gear to rotate. Because the adjustment gear works in conjunction with the sliding spur gear seat, it drives the sliding spur gear seat and the correction component on the sliding spur gear seat to slide along the inner wall of the frame, and the position of the correction component can be adjusted as needed. Simultaneously, the straightening motor is started and controlled to drive the straightening roller to rotate and adjust its position so that the outer wall of the straightening roller fits against both sides of the hot-rolled coil, serving as a guide and limiter. When the circular pressure sensor detects a fluctuation in the data, it transmits the data to the central control device of the cutting equipment and controls the straightening motor in the straightening assembly on that side to drive the straightening roller to rotate. The straightening roller touches the hot-rolled coil and pushes it in the opposite direction, causing the hot-rolled coil to reset.

[0009] Preferably, the anti-tilting mechanism includes a hanger fixedly connected to the top of the frame, a pressure contact assembly fixedly connected to the bottom of one end of the hanger, and a retractable rod assembly provided on the inner wall of the pressure contact assembly; The pressure contact assembly includes an upper connecting ring plate fixedly connected to the bottom of one end of the hanger.

[0010] Preferably, the upper feed inlet of the frame is provided with a plurality of built-in rollers that are rolled together, and the built-in rollers are used in conjunction with the pressure ball bearings.

A locking pin is rotatably connected to the inner wall of the sliding platform. The outer wall of the locking pin is tightly fitted and connected to the outer wall of the movable support frame. The locking pin's outer wall is tightly connected to the outer wall of the movable support frame. By rotating the locking pin, the movable support frame can be limited and released, so that the movable support frame can be removed and the hot-rolled coil can be replaced. A receiver / discharger is fixedly connected to the outer wall of the fixed support frame. The output shaft of the receiver / discharger is fixedly connected to a short connecting rod via a coupling. The short connecting rod is fixedly connected to a storage shaft via bolts. A fixing block is fixedly connected to the end of the storage shaft away from the short connecting rod via bolts. An operating hole is provided on one side of the frame. The operation hole facilitates the disassembly and assembly of the fixing block. In use, the hot-rolled coil to be processed can be placed on the storage shaft, and the storage shaft can be fixedly connected to the fixing block and the short connecting rod with bolts. Then, the receiver and discharge machine can be started and controlled. The hot-rolled coil can be transported by rotating the storage shaft, and then processed in conjunction with the laser cutting machine. The two ends of the sliding platform are rotatably connected to sliding short shafts; Among them, such as Figure 1 As shown, guide grooves are provided on both sides of the frame, and the end of the sliding short shaft away from the sliding platform is slidably connected to the inner wall of the guide groove. In use, the hydraulic cylinder is activated and controlled to pull back and forth. When the hot-rolled coil placed on the storage shaft reaches the end of its use, the hydraulic cylinder is activated and controlled to pull back and forth the sliding platform. The sliding short shaft slides along the inner wall of the guide inclined slide groove toward the laser cutting machine processing position, maximizing the delivery of the hot-rolled coil to the laser cutting machine processing position for cutting. The bottom of the sliding platform is provided with multiple auxiliary support components. Each auxiliary support component includes a connecting block provided at the bottom of the sliding platform. The bottom of the connecting block is fixedly connected to a second straight sleeve and a buffer spring.

The miniature telescopic hydraulic cylinder is used to extend and retract to adjust the position of the electric suction cup, and the electric suction cup is activated to pick up the cut product from the upper surface. The system also includes a micro-control motor and grippers. The micro-control motor is used to drive the grippers to rotate, and multiple grippers work together to pick up the cut product from the side. During use, the robotic arm is started and controlled. The position of the gripping disc can be rotated and adjusted. Depending on the shape and size of the product after the hot-rolled coil is cut, either a gripper or an electric suction cup can be used to pick up the material. The cut product is then sent to the feeding conveyor belt for outward transport.

[0013] Preferably, exhaust fans are installed at the four corners of the connection between the laser cutting machine and the frame, and an auxiliary gas delivery tank is fixedly connected to the outer wall of the laser cutting machine; The auxiliary gas delivery tank is used to provide the laser cutting machine with auxiliary gas during operation, ensuring the normal cutting process. The four exhaust fans slowly discharge the gas near the cutting position of the laser cutting machine, guiding the gas discharged from the auxiliary gas delivery tank so that it is evenly distributed on the hot-rolled coil, thereby ensuring a better cutting effect.

[0014] Compared with the prior art, the embodiments of this application have the following main advantages: By setting up and coordinating the frame, laser cutting machine, feeding monitoring mechanism, feeding correction mechanism, anti-warping mechanism, and guide rollers, this structure systematically solves the problem in the background technology of hot-rolled coil shifting due to changes in the cutting path, resulting in defective products on the side, through the closed-loop control logic of "monitoring-feedback-correction-limiting".

By setting up and using the frame, laser cutting machine, exhaust fan, and auxiliary gas delivery tank together, this structure significantly improves the quality of the heat-affected zone and the cleanliness of the environment during the laser cutting process through the synergistic effect of the auxiliary gas and exhaust system, ensuring the smoothness of the cut surface and the cutting stability, and indirectly improving the product qualification rate. By setting up and using the frame, laser cutting machine, material handling components, and feeding conveyor belt in combination, this combination enables automated and flexible picking and transfer of cut products, solving the problems of low efficiency, easy damage to finished products, or interference with the laser head caused by manual material handling.

The feeding monitoring mechanism 4 includes an inner seat assembly 401 fixedly connected to the inner wall of the frame 1, and a monitoring component 402 is movably connected to the inner wall of the inner seat assembly 401. Among them, there are two feed monitoring mechanisms 4, and the two feed monitoring mechanisms 4 are symmetrically arranged; The inner seat assembly 401 includes a vertical seat 4011 fixedly connected to the inner wall of the frame 1. A fixing plate 4012 is fixedly connected to the bottom of the vertical seat 4011. A vertical plate is fixedly connected to the outer wall of the fixing plate 4012.

The position between the two feeding monitoring mechanisms 4 can be adjusted according to the width of the hot-rolled coil, and then fixed on the frame 1 by bolts.

[0020] The monitoring component 402 includes a vertical connecting shaft 4023, an arc-shaped guide plate 4021 fixedly connected to the outer wall of the vertical connecting shaft 4023, an arc-shaped spring 4022 and an arc-shaped sleeve 4026 fixedly connected to the inner side of the arc-shaped guide plate 4021, a circular pressure block 4025 fixedly connected to one end of the arc-shaped spring 4022 and the arc-shaped sleeve 4026, and the circular pressure block 4025 and the circular pressure sensor 4013 are used in conjunction.

When the position of the hot-rolled coil deviates during the conveying process, the hot-rolled coil will deviate to one side, and the arc-shaped guide plate 4021 on one side will be subjected to force and rotate along the vertical connecting shaft 4023. The circular pressure block 4025 on the arc-shaped spring 4022 behind the arc-shaped guide plate 4021 will become larger due to the pressure of the arc-shaped spring 4022, and the data of the circular pressure sensor 4013 will fluctuate.

One end of the sliding straight tooth seat 501 is fixedly connected to a correction component 503, and the outer wall of the sliding straight tooth seat 501 is meshed with an adjustment shaft assembly 502. The feeding correction mechanism 5 and the feeding monitoring mechanism 4 are used together.

[0022] The correction assembly 503 includes a correction motor 5031 fixedly connected to the sliding spur gear seat 501. The output shaft of the correction motor 5031 is fixedly connected to a crank rod 5032 via a coupling. One end of the crank rod 5032 is fixedly connected to a correction roller 5033. The control shaft assembly 502 includes a control shaft 5021 that is slidably connected to the inner wall of the frame 1. The lower end of the control shaft 5021 is fixedly connected to a control gear 5022 and a locking gear 5023, respectively. Among them, the regulating gear 5022 is used in conjunction with the sliding spur gear seat 501, and the inner wall of the frame 1 is provided with a circular gear groove that is used in conjunction with the locking gear 5023. In use, pull the control shaft 5021 upward to lock the gear 5023 away from the circular gear groove, rotate the control shaft 5021 to drive the control gear 5022 to rotate. Since the control gear 5022 works in conjunction with the sliding spur gear seat 501, it drives the sliding spur gear seat 501 and the correction component 503 on the sliding spur gear seat 501 to slide along the inner wall of the frame 1, thereby adjusting the position of the correction component 503 as needed. Simultaneously, the straightening motor 5031 is started and controlled to drive the straightening roller 5033 to rotate, adjusting the position of the straightening roller 5033 so that the outer wall of the straightening roller 5033 fits against both sides of the hot-rolled coil, serving as a guide and limiting device. When the circular pressure sensor 4013 senses a fluctuation in the data, the circular pressure sensor 4013 transmits the data to the central control device of the cutting equipment, and controls the straightening motor 5031 in the straightening assembly 503 on that side to drive the straightening roller 5033 to rotate. The straightening roller 5033 touches the hot-rolled coil and pushes it in the opposite direction, so that the hot-rolled coil is reset.

[0023] The anti-tilting mechanism 6 includes a hanger 601 fixedly connected to the top of the frame 1. A pressure contact assembly 603 is fixedly connected to the bottom of one end of the hanger 601. A retractable rod assembly 602 is provided on the inner wall of the pressure contact assembly 603. The pressure contact assembly 603 includes an upper connecting ring plate 6035 fixedly connected to the bottom of one end of the hanger 601. A plurality of first straight sleeves 6034 are fixedly connected to the bottom of the upper connecting ring plate 6035. A pressure contact spring 6033 is fixedly connected to the bottom of the upper connecting ring plate 6035. A lower pressure seat 6031 is fixedly connected to one end of the first straight sleeves 6034 and the pressure contact spring 6033.

In use, by rotating and controlling the retracting rod 6021, the height of the lower pressure seat 6031 can be adjusted up and down as needed, thereby adjusting the pressing and limiting guiding function of the pressure contact ball 6032 at the bottom of the lower pressure seat 6031 on the hot-rolled coil according to the thickness of the hot-rolled coil.

[0024] Multiple built-in rollers 11 are rolledly connected to the inner wall of the upper feed port of the frame 1, and the built-in rollers 11 are used in conjunction with the pressure contact ball 6032.

[0025] It should be noted that in the current processing of hot-rolled coils, laser cutting equipment is frequently used for cutting. During the cutting process, the hot-rolled coil material is cut according to the pre-set travel path of the laser cutting equipment. However, as the cutting path progresses and changes, the hot-rolled coil will shift to a certain position. This shift may be large or small. When the shift is greater than the reserved portion on the edge of the material, the product will be defective due to cutting near the edge. Therefore, manual inspection and correction are required in real time, which results in a large workload and is prone to processing errors.

[0026] Specifically, in this embodiment, the solution mainly uses the frame 1, laser cutting machine 3, cutting baffle 2, feeding monitoring mechanism 4, feeding correction mechanism 5, anti-warping mechanism 6, guide roller 10, raw material placement rack mechanism 7, material picking component 8, feeding conveyor belt 9, built-in roller 11, exhaust fan 12, auxiliary gas conveying tank 13, and operation hole 14 for setup and coordination. In use, firstly, according to the cutting needs, the cutting stroke of the laser cutting machine 3 is set, and the hot-rolled coil to be cut is placed and installed on the storage shaft 707. The receiver and discharge motor 706 is started and controlled. The hot-rolled coil can be driven to rotate through the storage shaft 707 to transport the hot-rolled coil, and then cooperate with the laser cutting machine 3 for processing. The position between the two feeding monitoring mechanisms 4 can be adjusted according to the required width of the hot-rolled coil, and then fixed on the frame 1 with bolts. After the positions of the two feeding monitoring mechanisms 4 are adjusted, the hot-rolled coil to be cut passes smoothly and precisely through the feeding channel between the two arc-shaped guide plates 4021. When the position of the hot-rolled coil deviates during the conveying process, the hot-rolled coil will shift to one side, and the arc-shaped guide plate 4021 on one side will be subjected to force and rotate along the vertical connecting shaft 4023. The rear side of the arc-shaped guide plate 4021 The circular pressure block 4025 on the arc spring 4022 becomes more pressured by the arc spring 4022, causing the data of the circular pressure sensor 4013 to fluctuate. When the circular pressure sensor 4013 senses the data fluctuation, it transmits the data to the central control device of the cutting equipment and controls the straightening motor 5031 in the straightening assembly 503 on the side to drive the straightening roller 5033 to rotate. The straightening roller 5033 touches the hot-rolled coil and pushes it in the opposite direction, so that the hot-rolled coil is reset. By rotating and controlling the retracting rod 6021, the height of the lower pressure seat 6031 can be adjusted up and down as needed, thereby adjusting the pressing and limiting guiding function of the pressure contact ball 6032 at the bottom of the lower pressure seat 6031 on the hot-rolled coil according to the thickness of the hot-rolled coil. The laser cutting machine 3 is started and controlled for cutting. The robotic arm 802 is started and controlled to rotate and adjust the position of the gripping plate 804. Depending on the shape and size of the product after the hot-rolled coil is cut, the gripper 805 or electric suction cup 806 is selected to pick up the material and send the gripped and cut product to the feeding conveyor belt 9 for outward transport.

[0027] In this embodiment, the circular pressure sensor 4013 and the arc-shaped guide plate 4021 in the feeding monitoring mechanism 4 sense the offset trend of the coil plate in real time. Once the data fluctuates, the central control system immediately instructs the correction motor 5031 and correction roller 5033 in the feeding correction mechanism 5 on the same side to actively push the coil plate back to its original position, realizing automatic and rapid correction of the offset. At the same time, the anti-warping mechanism 6 applies stable vertical pressure to the coil plate through the cooperation of the pressure contact ball 6032 and the built-in roller 11, effectively preventing the material from warping under high-speed conveying or cutting stress. The guide roller 10 provides basic horizontal guidance. In summary, this combination not only ensures that the coil plate is always accurately fed along the preset cutting path, but also improves the stability of the processing process through multi-dimensional limiting, thereby ensuring the edge integrity and dimensional accuracy of the cut product and greatly improving the level of automation.

[0028] In a further preferred embodiment of the present invention, the raw material placement rack mechanism 7 includes a retractable hydraulic cylinder 701 embedded and fixedly connected to the inner wall of the frame 1. The telescopic end of the retractable hydraulic cylinder 701 is hinged to a sliding platform 702. A fixed support frame 704 is fixedly connected to the top of the sliding platform 702. A movable support frame 705 is slidably connected to the inner wall of the sliding platform 702. The fixed support frame 704 and the movable support frame 705 are used in cooperation. A locking pin 710 is rotatably connected to the inner wall of the sliding platform 702. The outer wall of the locking pin 710 is tightly fitted and connected to the outer wall of the movable support frame 705. The locking pin 710 is tightly connected to the outer wall of the movable support frame 705. By rotating the locking pin 710, the movable support frame 705 can be limited and released, so that the movable support frame 705 can be taken out and the hot-rolled coil can be replaced. A receiver / discharger 706 is fixedly connected to the outer wall of the fixed support frame 704. The output shaft of the receiver / discharger 706 is fixedly connected to a short connecting rod via a coupling. The short connecting rod is fixedly connected to a storage shaft 707 via bolts. A fixing block 708 is fixedly connected to the end of the storage shaft 707 away from the short connecting rod via bolts. An operation hole 14 is provided on one side of the frame 1. The operation hole 14 facilitates the disassembly and assembly of the fixing block 708. In use, the hot-rolled coil to be processed can be placed on the storage shaft 707, and the storage shaft 707 can be fixedly connected to the fixing block 708 and the short connecting rod by bolts. Then, the receiver and discharge motor 706 can be started and controlled. The hot-rolled coil can be transported by rotating the storage shaft 707, and then processed in conjunction with the laser cutting machine 3. The two ends of the sliding platform 702 are rotatably connected to sliding short shafts 709; Among them, such as Figure 1 As shown, guide inclined slide grooves are provided on both sides of the frame 1, and the end of the sliding short shaft 709 away from the sliding platform 702 is slidably connected to the inner wall of the guide inclined slide groove. In use, the hydraulic cylinder 701 is started and controlled. When the hot-rolled coil placed on the storage shaft 707 reaches the end of use, the hydraulic cylinder 701 is started and controlled to pull the sliding table 702. The sliding short shaft 709 slides along the inner wall of the guide inclined slide groove toward the processing position of the laser cutting machine 3, maximizing the delivery of the hot-rolled coil to the processing position of the laser cutting machine 3 for cutting. The bottom of the sliding platform 702 is provided with a plurality of auxiliary support components 703. The auxiliary support components 703 include a connecting block 7031 provided at the bottom of the sliding platform 702. The bottom of the connecting block 7031 is fixedly connected to a second straight sleeve 7032 and a buffer spring 7033. The bottom of the second straight sleeve 7032 and the buffer spring 7033 is fixedly connected to a roller 7034. The auxiliary support component 703 provides auxiliary support for the sliding platform 702.

[0029] In this embodiment, the hydraulic cylinder 701 in the raw material placement rack mechanism 7 drives the sliding platform 702 to slide along the guide inclined slide groove. When the coil on the storage shaft 707 reaches its end, this action can deliver the remaining material to the processing station of the laser cutting machine 3 as much as possible, significantly reducing material waste at the tail end. Simultaneously, the coordinated design of the movable support frame 705, locking pin 710, and operating hole 14 enables rapid replacement and fixation of the coil. The unwinding motor 706 directly drives the storage shaft 707 to actively unwind, ensuring synchronization between the feeding speed and the laser cutting machine 3. The auxiliary support assembly 703 provides stable support for the entire sliding platform. Therefore, this combination effectively extends the continuous processing time for a single feeding, improves material utilization, simplifies the operation process, and collaboratively constructs a highly efficient, low-loss automated processing line with the laser cutting machine 3.

[0030] In a further preferred embodiment of the present invention, exhaust fans 12 are respectively provided at the four corners of the connection between the laser cutting machine 3 and the frame 1, and an auxiliary gas delivery tank 13 is fixedly connected to the outer wall of the laser cutting machine 3. The auxiliary gas delivery tank 13 is set up and used in conjunction with the laser cutting machine 3 to provide corresponding auxiliary gas delivery during operation, ensuring the normal cutting process. The four exhaust fans 12 are set up to slowly discharge the gas near the cutting position of the laser cutting machine 3, and guide the gas discharged from the auxiliary gas delivery tank 13, so that the gas discharged from the auxiliary gas delivery tank 13 is evenly spread on the hot-rolled coil, thereby ensuring a better cutting effect of the hot-rolled coil.

[0031] In this embodiment, the auxiliary gas delivery tank 13 provides the laser cutting machine 3 with necessary combustion or protective gases, such as oxygen and nitrogen, which are crucial for blowing away molten slag, cooling the cutting edges, and preventing oxidation. However, uneven gas flow can lead to fluctuations in cutting quality. In this invention, four exhaust fans 12 are arranged at the four corners where the laser cutting machine 3 connects to the frame 1. The negative pressure they generate not only quickly removes the smoke and splatter generated during cutting, protecting the optical lenses and the operating environment, but more importantly, it also "guides" the gas ejected from the auxiliary gas delivery tank 13, allowing the auxiliary gas to spread more evenly and smoothly over the cutting path of the hot-rolled coil. This synergistic effect optimizes the dynamic gas environment in the cutting zone, resulting in narrower, more vertical, and smoother cuts, reducing the heat-affected zone, and avoiding laser energy attenuation due to poor smoke exhaust. Ultimately, this ensures that the laser cutting machine 3 can continuously and with high quality complete the processing task.

[0032] In a further preferred embodiment of the present invention, the material handling component 8 includes an upper support base 801 fixedly connected to the top of the frame 1. A robotic arm 802 is fixedly connected to the upper end of the upper support base 801. A spherical connector 803 is connected to the output end of the robotic arm 802. A gripping disk 804 is hinged to the bottom of the robotic arm 802 through the spherical connector 803. A plurality of micro-controlled motors are embedded in the inner wall of the gripping disk 804. A micro-rotating shaft is fixedly connected to the output shaft of the micro-controlled motor through a coupling. A gripper 805 is fixedly connected to one end of the micro-rotating shaft. The gripper 805 is rotatably connected to the gripping disk 804 through the micro-rotating shaft. A micro telescopic hydraulic cylinder is fixedly connected to the center of the inner wall of the gripping disk 804. An electric suction cup 806 is fixedly connected to the telescopic end of the micro telescopic hydraulic cylinder. The micro telescopic hydraulic cylinder and the electric suction cup 806 are used together to start and control the extension and retraction of the electric suction cup 806 to adjust its position, and to start the electric suction cup 806 to pick up the upper surface of the cut product. The micro-control motor and the gripper 805 are used together to start and control the micro-control motor to drive the gripper 805 to rotate. Multiple grippers 805 work together to pick up the cut product from the side. In use, the robotic arm 802 is started and controlled, the position of the gripping disc 804 can be rotated and adjusted, and the gripper 805 or electric suction cup 806 can be selected to pick up the material according to the shape and size of the product after the hot-rolled coil is cut, and the cut product after gripping is sent to the feeding conveyor belt 9 for outward conveying.

[0033] In this embodiment, the core of the material handling component 8 lies in its multi-mode gripping capability. The robotic arm 802 provides a wide range of spatial positioning, allowing the gripping disc 804 to be precisely moved above the cut product. The gripping disc 804 integrates two gripping mechanisms: multiple grippers 805 driven by micro-controlled motors are used to grip regularly shaped products with a certain thickness from the side; the electric suction cup 806 at the center is used to pick up products with flat surfaces, easily scratched surfaces, or thin sheets. A micro telescopic hydraulic cylinder can adjust the extension height of the electric suction cup 806 to adapt to the thickness of different products. This composite design of "gripping + suction" allows the equipment to flexibly select the most suitable gripping method according to the actual shape, size, and material characteristics of the cut product, avoiding product drop or surface damage caused by a single gripping method. The gripped product is placed smoothly on the feeding conveyor belt 9, which automatically transports it to the next process or finished product area. The entire process requires no manual intervention and is precisely synchronized with the cutting cycle of the laser cutting machine 3, effectively eliminating material handling bottlenecks and achieving full automation from raw material input to finished product output.
