Description

Technical Field

[0001] This invention relates to the field of metal sheet transportation technology, and in particular to an unmanned material handling and switching platform for metal sheets. Background Technology

[0002] In a sheet metal rolling production line, the rolled high-temperature sheet metal needs to be transferred to a cooling bed for cooling via a conveying device. Then, a material guiding mechanism switches between different cooling beds to complete the subsequent finishing process. Currently, sheet metal is mostly transported using a combination of roller conveyors, walking beam conveyors, and transverse trolleys. The material guiding and switching between cooling beds mainly relies on lifting skirts, fixed guide plates, and claw mechanisms to complete the path conversion.

[0003] Existing transportation and material guiding methods have several shortcomings: First, the reliability of conveyor connections is poor. Impacts, deviations, and jamming easily occur at the junction of the roller conveyor and the cooling bed, easily causing scratches and warping deformation on the sheet surface, affecting product quality. Second, the flexibility of material guiding switching is low. Traditional guiding mechanisms are mostly fixed or semi-fixed structures, and the switching action between different cooling beds is cumbersome and slow, unable to adapt to the high-speed continuous rolling rhythm. Third, the equipment has weak adaptability. For sheets of different thicknesses and widths, the material guiding height, gap, and angle need to be manually adjusted on-site, resulting in low adjustment accuracy, long adjustment time, and poor production line flexibility. Fourth, the stability and durability of the mechanism are insufficient. The material guiding and transfer components are subjected to high temperature, heavy load, and impact conditions for a long time, making them prone to wear and deformation, leading to asynchronous actions, reduced positioning accuracy, and frequent failures. Fifth, the degree of automation is low, relying heavily on manual intervention and on-site operation, resulting in low production efficiency, high labor intensity, and high maintenance costs, which restricts the operating efficiency and product qualification rate of the entire rolling line.

[0004] The current traditional transportation and material switching modes can no longer meet the needs of efficient, high-precision, and highly automated production of sheet metal, becoming a prominent problem restricting the improvement of quality and efficiency of rolling lines. Summary of the Invention

[0005] The technical problem this invention aims to solve is that the current traditional transportation and material feeding switching modes are no longer able to meet the needs of efficient, high-precision, and highly automated production of metal sheets, thus limiting the improvement of rolling lines in terms of quality and efficiency.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a metal sheet unmanned material guiding and switching platform, including a horizontal main frame, a number of horizontally arranged conveying rollers are provided on the upper end of the horizontal main frame, a lateral separation port is opened on the side wall of the horizontal main frame, an electrically controlled translational material guiding frame is inserted into the lateral separation port, and an electrically controlled lifting separation bracket is movably assembled inside the electrically controlled translational material guiding frame.

[0007] An embedded locking mechanism is installed on the inner wall of the lateral separation port. The electrically controlled translational guide frame has side locking slots on both sides that cooperate with the embedded locking mechanism. The embedded locking mechanism fixes the electrically controlled translational guide frame inside the lateral separation port by inserting a movable locking tongue into the side locking slot.

[0008] The electrically controlled translational guide frame includes a side back plate, side mounting frames fixed to both ends of the side of the side back plate, and an electrically controlled rotary conveyor belt installed at the lower end of the side mounting frames.

[0009] The electrically controlled rotary conveyor track includes a longitudinal lifting strut mounted on the bottom surface of the side assembly frame, a transverse rotating strut hinged to the lower end of the inner side of the side assembly frame, an assembly bushing axially fitted on the bottom extension end of the longitudinal lifting strut, a bottom support frame movably fitted on the assembly bushing, and an electrically controlled track installed inside the bottom support frame.

[0010] The side-mounted assembly frame is internally fitted with a lateral longitudinal beam that works in conjunction with the electrically controlled lifting separation bracket.

[0011] The electrically controlled lifting separation bracket includes a longitudinal lifting guide rail installed inside the lateral longitudinal beam, a longitudinal electrically controlled lead screw movably installed inside the longitudinal lifting guide rail, and a lifting support frame located inside the side assembly frame at both ends of the lateral back plate. The lifting support frame is threadedly fitted with the longitudinal electrically controlled lead screw through internal threaded lifting blocks at both ends.

[0012] The lifting support frame includes a central crossbeam and inclined connecting sections that bend downwards on both sides of the central crossbeam. An embedded pressure sensing module and a temperature sensing module are fixedly installed on the upper end of the central crossbeam.

[0013] The upper part of the side backplate is equipped with a status warning light and a smart optical lens.

[0014] A lateral control arm that cooperates with a horizontally rotating strut is welded and fixed to the outer wall of the bottom support frame. The horizontally rotating strut is movably connected to the lateral control arm through its extended end.

[0015] The embedded locking mechanism consists of an embedded mounting base fixed on the inner wall of the lateral separation port, a telescopic locking tongue slidably installed inside the telescopic port of the embedded mounting base, a compression spring for controlling the telescopic locking tongue, and an electromagnet for controlling the compression spring.

[0016] The beneficial effects of this invention are: (1) The present invention realizes unmanned material feeding and switching through intelligent optical lens visual recognition, sensor module detection and linkage control of various electronic control mechanisms, which eliminates the need for manual on-site operation, reduces labor intensity and improves the level of automation; (2) The conveying connection is highly stable. The conveying rollers are combined with the electrically controlled rotary conveyor belt and the electrically controlled lifting separation bracket to avoid impact, deviation and jamming of the plate, reduce scratches and warping deformation on the plate surface, and improve product quality. (3) The material switching is flexible and adaptable. The translation of the electrically controlled translational material guide frame, the lifting of the electrically controlled lifting separation bracket, and the angle adjustment of the electrically controlled rotary conveyor belt can be adapted to metal plates of different thicknesses and widths. Moreover, the switching response between different cooling beds is fast and matches the high-speed rolling rhythm. (4) The equipment has good structural stability and durability. The embedded locking mechanism realizes the firm fixation of the electrically controlled translational guide frame. The assembly structure of each transmission component is adapted to high temperature and heavy load conditions, reducing wear and failure and reducing maintenance costs. (5) The equipment operating status can be monitored in real time. The status warning lights and various sensor modules can be used to promptly report the status of the equipment and the sheet metal, which facilitates remote monitoring and troubleshooting of the production line and improves the operating efficiency and product qualification rate of the entire rolling line.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The unmanned material handling and switching platform for metal sheets shown includes a horizontal main frame 1. Several horizontally arranged conveying rollers 2 are provided on the upper end of the horizontal main frame 1. The conveying rollers 2 are connected to an external drive motor to realize the horizontal conveying of metal sheets. A lateral separation port 3 is opened on the side wall of the horizontal main frame 1. An electrically controlled translational material guide frame 4 is inserted into the lateral separation port 3. The electrically controlled translational material guide frame 4 can move horizontally along the lateral separation port 3 to realize docking with different cooling beds. An electrically controlled lifting separation bracket 5 is movably assembled inside the electrically controlled translational material guide frame 4. The electrically controlled lifting separation bracket 5 can realize lifting and adjustment to adapt to the lifting and guiding of sheets of different thicknesses.

[0028] An embedded locking mechanism 6 is installed on the inner wall of the side separation port 3. The electrically controlled translational guide frame 4 has side locking slots 7 on both sides that cooperate with the embedded locking mechanism 6. The embedded locking mechanism 6 consists of an embedded mounting base 61 fixed on the inner wall of the side separation port 3, a telescopic locking tongue 62 slidably installed inside the telescopic port of the embedded mounting base 61, a compression spring 63 for controlling the telescopic locking tongue 62, and an electromagnet 64 for controlling the compression spring 63. When the electrically controlled translational guide frame 4 is translated to the designated position, the electromagnet 64 is de-energized, the compression spring 63 resets and pushes the telescopic locking tongue 62 to extend and insert into the side locking slot 7, firmly fixing the electrically controlled translational guide frame 4 inside the side separation port 3 to prevent displacement during equipment operation. When it is necessary to adjust the position of the electrically controlled translational guide frame 4, the electromagnet 64 is energized to attract the telescopic locking tongue 62 and compress the compression spring 63, causing the telescopic locking tongue 62 to disengage from the side locking slot 7 and release the fixation.

[0029] The electrically controlled translational guide frame 4 includes a side back plate 41, side mounting frames 42 fixed at both ends of the side of the side back plate 41, and an electrically controlled rotary conveyor belt 43 installed at the lower end of the side mounting frames 42. The side mounting frames 42 are internally fitted with side longitudinal beams 44 that cooperate with the electrically controlled lifting separation bracket 5. The side back plate 41 is equipped with a status warning light 8 and an intelligent optical lens 9. The intelligent optical lens 9 is used for visual identification of the specifications, position and operating status of the metal sheet. The status warning light 8 uses different colored lights to reflect the operating, fault, standby and other statuses of the equipment, which is convenient for remote monitoring.

[0030] The electrically controlled lifting separation bracket 5 includes a longitudinal lifting guide rail 51 installed inside the lateral longitudinal beam 44, a longitudinal electrically controlled lead screw 52 movably installed inside the longitudinal lifting guide rail 51, and a lifting support frame 53 located inside the side assembly frames 42 at both ends of the side of the lateral back plate 41. The lifting support frame 53 is threadedly fitted to the longitudinal electrically controlled lead screw 52 through internally threaded lifting blocks 54 at both ends. The longitudinal electrically controlled lead screw 52 is connected to a servo motor, which drives the longitudinal electrically controlled lead screw 52 to rotate, thereby causing the internally threaded lifting blocks 54 to move along the longitudinal lifting direction. The guide rail 51 moves up and down, thereby adjusting the height of the lifting support frame 53. The lifting support frame 53 includes a central crossbeam 531 and inclined connecting sections 532 that bend downward on both sides of the central crossbeam 531. An embedded pressure sensing module 55 and a temperature sensing module 56 are fixedly installed on the upper end of the central crossbeam 531. The embedded pressure sensing module 55 detects the pressure between the plate and the lifting support frame 53 to prevent the plate from being deformed by pressure. The temperature sensing module 56 detects the temperature of the high-temperature plate to provide data reference for subsequent processes.

[0031] The electrically controlled rotary conveyor track 43 includes a longitudinal lifting strut 431 mounted on the bottom surface of the side mounting frame 42, a transverse rotating strut 432 hinged to the lower end of the inner side of the side mounting frame 42, a mounting bushing 433 axially fitted on the bottom extension end of the longitudinal lifting strut 431, a bottom support frame 434 movably fitted on the mounting bushing 433, and an electrically controlled track 435 installed inside the bottom support frame 434. A lateral control mechanism that cooperates with the transverse rotating strut 432 is welded and fixed to the outer wall of the bottom support frame 434. The control arm 436 has a horizontal rotating support rod 432 that is movably connected to the lateral control arm 436 through its extended end. The longitudinal lifting support rod 431 is an electro-hydraulic support rod that can extend and retract to adjust the height of the bottom support frame 434. The horizontal rotating support rod 432 is an electric push rod. The extension and retraction of the push rod can push the lateral control arm 436 to rotate the bottom support frame 434 around the assembly bushing 433, thereby adjusting the angle of the electrically controlled track 435 to adapt to the docking angle of different cooling beds. The electrically controlled track 435 enables the turning and conveying of metal plates.

[0032] Working principle and process of the present invention The working principle of this invention is as follows: A horizontal main frame 1 serves as the foundation support. Metal sheets are horizontally conveyed via conveyor rollers 2. A smart optical lens 9 and various sensing modules enable real-time detection of the sheet condition and equipment operating status. The electrically controlled translational guide frame 4 horizontally moves to connect with different cooling beds. An embedded locking mechanism 6 secures its position. The electrically controlled lifting separation bracket 5 adjusts to accommodate sheets of different thicknesses. The electrically controlled rotating conveyor belt 43 adjusts its height and angle to ensure precise connection between the sheet and different cooling beds. All electrical control mechanisms are linked through a central control system, enabling unmanned material switching operations. The smart optical lens 9, equipped with an industrial high-definition visual imaging module, a laser rangefinder, and a smart image recognition algorithm, is integrated into the upper side backplate 41 of the electrically controlled translational guide frame 4. It provides core visual perception data for unmanned operation. The recognition process follows a closed-loop model of real-time imaging, feature extraction, data analysis, and command feedback. The specific intelligent recognition method is as follows: Basic sheet metal specification identification: The intelligent optical lens 9 captures real-time dynamic images of the metal sheet metal on the conveyor roller 2 through a high-definition imaging unit. It uses an image edge detection algorithm to extract the contour features of the sheet metal and quickly analyzes the width, length, and flatness data of the sheet metal. At the same time, in conjunction with the laser ranging module, it emits laser beams to the bottom and surface of the sheet metal and accurately calculates the thickness of the sheet metal by measuring the difference in reflection distance. All specification data are transmitted to the central control system in real time, providing basic parameters for the height adjustment of the electrically controlled lifting separation bracket 5 and the angle adaptation of the electrically controlled rotating conveyor belt 43.

[0033] Sheet position and motion status recognition: The camera dynamically tracks the movement trajectory of the sheet on the conveying roller 2 using the frame difference method, and identifies the real-time conveying position, moving speed, and whether there are any deviation or offset problems. If the sheet position is detected to be offset, a deviation signal is immediately sent to the central control system. The system can then finely adjust the rotation speed of the conveying roller 2 or the initial position of the electrically controlled translational guide frame 4 in real time to ensure that the sheet is accurately aligned with the electrically controlled lifting separation bracket 5 and avoid jamming and impact problems.

[0034] Surface and temperature-assisted identification of sheet material: The intelligent optical lens 9 can work with the temperature sensing module 56 on the lifting support frame 53 to assist in detecting the temperature distribution on the surface of the sheet material through infrared visual imaging function, and identify whether there are local high temperature areas on the sheet material; at the same time, it can perform preliminary visual inspection of the surface of the sheet material to identify whether there are obvious rolling scratches, warping and other defects, providing preliminary data for quality screening of subsequent processes.

[0035] Equipment linkage and adaptation recognition: The lens can visually calibrate the position and angle of the docking port of the target cooling bed, and transmit the spatial coordinate data of the docking end of the cooling bed to the central control system. The system combines the plate specification data to automatically calculate the lifting height, turning angle and translation distance of the electrically controlled rotary conveyor belt 43 and the electrically controlled translational guide frame 4, so as to achieve precise linkage and adaptation between the equipment, the cooling bed and the plate.

[0036] Abnormal status identification and feedback: During the entire material feeding and switching process, the camera continuously identifies whether the board is stuck or tilted, and whether the electrical control mechanism has any abnormal status such as action deviation or structural interference. Once an abnormality is detected, an alarm signal is immediately sent to the central control system, and the red alarm of status warning light 8 is triggered at the same time. The system automatically stops the equipment to prevent the fault from escalating.

[0037] The recognition data from the intelligent optical lens 9 is linked in real time with the detection data from the embedded pressure sensing module 55 and temperature sensing module 56 to achieve dual perception of visual recognition and sensor detection, ensuring the accuracy of the recognition results and providing reliable data support for unmanned material feeding switching.

[0038] Four electrically controlled rotary conveyor tracks 43 are symmetrically arranged at the lower end of the electrically controlled translational guide frame 4 of this device, corresponding to the four corners of the electrically controlled translational guide frame 4. The overall lifting and lowering adjustment of the electrically controlled rotary conveyor tracks 43 is achieved by the synchronous lifting and lowering of the diagonally longitudinal lifting support rods 431. Then, the steering adjustment of a single track is achieved by the independent extension and retraction of the transverse rotating support rods 432. Finally, through the coordinated lifting and lowering and steering linkage of the four tracks, the translation and steering movements of the entire electrically controlled translational guide frame 4 are completed. During the adjustment process, the tracks always maintain a reasonable gap with the ground to avoid friction with the ground, which greatly reduces the power consumption and resistance of the equipment. The specific control method is as follows: Four electrically controlled rotary conveyor tracks 43 are arranged in a rectangular array at the four corners of the lower end of the electrically controlled translational guide frame 4. With the center of the frame as the symmetrical point, they are divided into two groups of diagonal tracks. The longitudinal lifting support rods 431 of each group of diagonal tracks are used as synchronous control units, and the transverse rotating support rods 432 are used as independent control units. The raising and lowering of the tracks are controlled by the synchronous extension and retraction of the longitudinal lifting support rods 431, so as to adjust the gap between the frame and the ground. The turning angle of the corresponding track is controlled by the extension and retraction of a single transverse rotating support rod 432. By coordinating the turning angles of the four tracks and adjusting the speed difference, the translation and turning of the entire electrically controlled translational guide frame 4 are realized. The tracks only contact the ground during the entire process, without friction or interference.

[0039] The lifting control is achieved by synchronously driving the diagonally arranged longitudinal lifting struts 431. The longitudinal lifting struts 431 are electro-hydraulic struts, which are linked with the hydraulic drive unit of the central control system. The specific control method is as follows: When the electrically controlled translational guide frame 4 needs to be pushed out from the side separation port 3 and moved, the central control system issues a lifting command. The four longitudinally placed lifting struts 431 on the two diagonal lines extend synchronously, pushing the bottom support frame 434 to move downward, driving the electrically controlled track 435 to descend synchronously until the electrically controlled track 435 contacts the ground, and lifting the entire electrically controlled translational guide frame 4, so that the bottom of the frame forms a reasonable gap with the ground, avoiding friction caused by the frame contacting the ground.

[0040] When the electrically controlled translational guide frame 4 is translated to the designated position and fixed by the embedded locking mechanism 6, the central control system issues a reset command. The four longitudinally placed lifting struts 431 on the two diagonals retract synchronously, pulling the bottom support frame 434 upward, which in turn drives the electrically controlled track 435 to rise synchronously until the bottom of the frame is in contact with the ground and a gap is formed between the track and the ground to ensure the stability of the frame.

[0041] If it is necessary to adapt to the docking ends of the cooling bed at different heights, the overall tilting and lifting of the electrically controlled track 435 can be achieved by the differentiated synchronous extension and retraction of two sets of diagonally longitudinally placed lifting struts 431, which can adapt to the height difference of the cooling bed and keep the track free from ground friction throughout the process.

[0042] Translation control is achieved through the synchronous steering and synchronous speed of four electrically controlled rotary conveyor tracks 43, combined with the lifting support of diagonally longitudinally placed lifting struts 431, ensuring the smoothness of the translation process. Specific control method: Linear translation: Based on the position of the target cooling bed, the central control system sends synchronous extension and retraction commands to the four transverse rotating support rods 432, causing the four electrically controlled rotary conveyor tracks 43 to turn at an angle consistent with the translation direction; then, the diagonal longitudinal lifting support rods 431 extend synchronously, raising the frame and bringing the tracks into contact with the ground; finally, the central control system controls the four electrically controlled tracks 435 to run synchronously at the same speed. Through the synchronous movement of the tracks, the entire electrically controlled translational guide frame 4 is driven to move linearly in the specified direction until it reaches the target position.

[0043] Fine-tuning translation: If a small adjustment to the position of the frame is required, it can be achieved by a slight difference in the rotational speed of the diagonal track on one side, or by adjusting the steering angle of the corresponding track by a small extension and retraction of a single transverse rotating strut 432, so as to achieve a small-distance translation and fine-tuning of the frame to meet the requirements of precise docking with the cooling bed.

[0044] Steering control is achieved through differentiated steering and speed coordination of four electrically controlled rotary conveyor tracks 43. Utilizing the lifting support of diagonally longitudinally mounted lifting struts 431, ground friction is eliminated during frame steering. Specific control method: In-situ turning: Suitable for scenarios where the frame needs to be turned at a small angle to adjust the docking angle. The central control system first controls the diagonal longitudinal lifting support rod 431 to extend, raising the frame so that the tracks contact the ground; then it sends reverse turning commands to the two diagonal tracks, such as the left front track and the right rear track turning 90°, and the right front track and the left rear track turning -90°; finally, it controls the four electrically controlled tracks 435 to run synchronously at the same speed. Through the reverse movement of the diagonal tracks, the entire electrically controlled translational guide frame 4 is driven to turn in place around the central axis until it is adjusted to the target angle. Throughout the process, the tracks only rotate and move, without any ground sliding friction.

[0045] Curve steering: Suitable for scenarios where the frame needs to turn at a large angle and move in a specified direction. The central control system sends differentiated extension and retraction commands to the four transverse rotating struts 432 according to the steering arc, so that the four electrically controlled tracks 435 turn at different angles (the inner track turns at a smaller angle, and the outer track turns at a larger angle); at the same time, it controls the inner track and the outer track to form a reasonable speed difference (the inner track rotates slower, and the outer track rotates faster); through the dual coordination of angle and speed, the entire frame is driven to turn and move along the specified curved trajectory, realizing the synchronous completion of large-angle steering and translation, and the tracks are always in rolling contact with the ground, with no frictional resistance.

[0046] By synchronously raising and lowering the diagonally longitudinally placed lifting struts 431, the lifting consistency of the four electrically controlled rotary conveyor tracks 43 is ensured, preventing the frame from tilting. At the same time, the independent extension and retraction of the transversely placed rotating struts 432 enables the track to turn. Combined with the adjustment of the track speed difference, the translation and turning of the frame can be achieved. During the entire adjustment process, the electrically controlled rotary conveyor tracks 43 only make contact with the ground by rolling, without sliding friction or interference between the structure and the ground. This significantly reduces the power consumption and mechanical resistance of the equipment, reduces track wear, and improves the durability and operational stability of the equipment.

[0047] The specific working process is as follows: First, when the equipment is in standby mode, the electrically controlled translational guide frame 4 retracts into the side separation port 3, the electrically controlled lifting separation support 5 is in a low position, and the electrically controlled rotary conveyor belt 43 is in a horizontal standby state. The status warning light 8 is green to indicate standby. Second, after rolling, the metal sheet is conveyed to the conveyor roller 2 of the horizontal main frame 1. The conveyor roller 2 drives the sheet to move horizontally, and the intelligent optical lens 9 identifies the width, thickness, and position of the sheet in real time and transmits the data to the central control system. Third, the central control system issues a control signal based on the sheet specifications and the target cooling bed position. The command-controlled electrically controlled translational guide frame 4 moves horizontally along the lateral separation port 3 to the designated docking position. Then, the electromagnet 64 of the embedded locking mechanism 6 is de-energized, and the compression spring 63 pushes the telescopic locking tongue 62 into the side locking groove 7, completing the fixation of the electrically controlled translational guide frame 4. In the fourth step, the central control system drives the longitudinally placed electrically controlled lead screw 52 to rotate according to the plate thickness, causing the lifting support frame 53 to rise along the longitudinally placed lifting guide rail 51 until the central crossbeam 531 contacts the bottom of the plate. The embedded pressure sensor module 55 detects the pressure value and feeds it back to the control system to ensure appropriate pressure and prevent plate deformation. In the fifth step, the central control system controls the extension and retraction of the longitudinal lifting strut 431 and the push action of the transverse rotating strut 432 according to the docking angle of the target cooling bed. The longitudinal lifting strut 431 drives the bottom support frame 434 to adjust its height, and the transverse rotating strut 432 pushes the lateral control arm 436 to rotate the bottom support frame 434, so that the electrically controlled track 435 is adjusted to the specified angle and precisely connected with the conveying end of the target cooling bed. In the sixth step, the electrically controlled lifting separation bracket 5 continues to rise, lifting the plate off the conveying roller 2, and then the electrically controlled... The track 435 starts, driving the plate to be conveyed to the target cooling bed along the adjusted angle, completing the material guide switching; in the seventh step, after the plate is conveyed, the electrically controlled lifting separation bracket 5 descends and resets, and the electrically controlled rotary conveyor track 43 returns to the horizontal state. If it is necessary to switch to another cooling bed, the embedded locking mechanism 6 is energized to release the fixation, and the electrically controlled translational guide frame 4 is translated to the new docking position, repeating the above steps; if the equipment malfunctions, the intelligent optical lens 9 or the sensor module detects the abnormality and feeds it back to the control system, the status warning light 8 lights up red, and the equipment stops running, which is convenient for staff to remotely troubleshoot the fault.
