Description

Technical Field

[0001] This utility model relates to the field of casting technology, specifically to a device for rapidly identifying the number of castings. Background Technology

[0002] Billet marking is a crucial step in the steel production process, primarily used to identify and manage billets, ensuring traceability and quality control throughout the production process. Billet marking is a fundamental measure for achieving efficient, precise, and traceable production in the steel industry, spanning the entire lifecycle from continuous casting to finished product, and is essential for quality control and process optimization.

[0003] The existing billet marking device spans each flow, confirming and marking the billet flow information by moving back and forth. This requires constantly starting and stopping the roller conveyor for each flow to bring the billet to a fixed position before the marking machine moves laterally to the corresponding roller conveyor for marking. This project involves a large initial investment, high construction difficulty and cost, and a huge workload for subsequent equipment maintenance. In the alternative fixed marking machine solution, while the marking device installed on the collection roller conveyor is convenient to use and has low maintenance costs, it cannot effectively identify billet flow information, making product traceability difficult. Utility Model Content

[0004] The purpose of this invention is to overcome the problems of complex operation, low efficiency, and difficulty in tracing products in existing billet marking devices, and to provide a device for quickly marking the billet flow number. This device simplifies roller conveyor operation, improves work efficiency, and realizes the marking of flow number information, making product traceability more convenient and accurate.

[0005] To achieve the above objectives, this utility model provides a device for rapidly identifying the flow sequence of a cast billet. This device includes a billet exit section vision system, a flow sequence binding module, and a fixed marking unit. The billet exit section vision system is installed above the post-cutting conveyor rollers and the steel transfer machine to capture the billet's number and position in real time. The flow sequence binding module is configured to associate the billet's number with the flow sequence information via an image processing server and transmit it to a display screen for real-time display. The fixed marking unit is configured to communicate with the flow sequence binding module and mark the collected billets according to the binding information.

[0006] Preferably, the billet exit vision system includes a dual-spectrum camera, which is connected to the post-cutting conveyor rollers and the gantry above the steel transfer machine via a telescopic and steerable adjustable arm.

[0007] Preferably, the outer cover of the dual-spectrum camera is equipped with a high-temperature resistant protective cover.

[0008] Preferably, at least two dual-spectrum cameras are located at the center point above the side of the post-cutting conveyor roller and the steel transfer machine, respectively, and are both configured to cover and capture all the cast billets on the post-cutting conveyor roller and the steel transfer machine.

[0009] Preferably, the post-cutting conveyor rollers include parallel double-line conveyor rollers, with each conveyor roller and the steel transfer machine configured to be connected in a one-to-one correspondence.

[0010] Preferably, the fixed marking unit is a marking robot, and a collection roller conveyor is connected between the marking robot and the steel transfer machine. The collection roller conveyor is configured to collect the billets loaded and unloaded by the steel transfer machine and transport them to the marking area of ​​the marking robot.

[0011] Preferably, the device for rapidly identifying the flow of a billet further includes an infrared sensor for detecting the position and temperature of the high-temperature billet. The infrared sensor is configured to cooperate with a dual-spectrum camera to trigger information capture when each billet leaves the flow roller.

[0012] Preferably, the dual-spectrum camera has a visible light mode and an infrared mode. The visible light mode is used to capture the position of the billet end face to form a real-time information marker, and the infrared mode is used to identify the billet outline and position information and realize the binding of flow sequence information.

[0013] Through the above technical solution, in the information capture stage, the billet passes through the billet exit roller conveyor, and the camera captures the billet exit position coordinates, and the system automatically binds the flow sequence information. In the data transmission stage, the flow sequence data is sent to the collection area server through the industrial ring network and displayed on a large screen on site. Finally, in the marking execution stage, the billet enters the collection roller conveyor, and the robot marks it according to the bound information. In this way, the departure of the billet from the flow sequence roller conveyor is determined by an infrared sensor as the start of the process. The high-temperature camera identifies each billet and generates a number (including flow sequence information). This information moves with the lateral movement of the billet, and the relevant data is transmitted to the computer. After being processed by image recognition software, the data is displayed in real time, and the data is sent to the marking robot. When the billet enters the collection area after leaving the cooling bed, the robot marks the flow sequence according to the recognition signal. Attached Figure Description

[0017] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0018] In this utility model, unless otherwise stated, directional terms such as "above," "outer," "side," and "center point" contained in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0019] See Figure 1 This utility model provides a device for quickly identifying the flow number of a cast billet. The device includes a billet exit section vision system, a flow number binding module, and a fixed numbering unit. The billet exit section vision system is installed above the post-cutting conveyor roller 1 and the steel transfer machine 2 to capture the number and position of the cast billet 3 in real time. The flow number binding module is configured to associate the number of the cast billet 3 with the flow number information through an image processing server and transmit it to the display screen 4 for real-time display. The fixed numbering unit is configured to communicate with the flow number binding module and spray numbers onto the cast billet 3 after it has been collected and unloaded, according to the binding information.

[0020] In this embodiment, the preferred billet segment vision system includes a dual-spectrum camera 5, which is connected to the gantry above the post-cutting conveyor roller 1 and the steel transfer machine 2 via a telescopic and steerable adjusting arm. Furthermore, the dual-spectrum camera 5 is equipped with a visible light mode and an infrared mode. The visible light mode can capture the position of the end face of the billet 3 to form a real-time information marker, while the infrared mode can identify the outline and position information of the billet 3 and achieve flow sequence information binding. Simultaneously, mounting the dual-spectrum camera 5 to the gantry via the adjusting arm not only facilitates adjusting the specific orientation of the dual-spectrum camera 5 according to the requirement of full coverage of the camera area, but also provides a more stable gantry structure compared to direct mounting on mobile equipment, reducing image blurring caused by mechanical vibration.

[0021] The surface temperature of the cut steel billet is typically as high as 800-1200℃, and even if the camera is mounted on a gantry, it will still be subjected to strong heat radiation. To solve the above technical problems, it is preferable to install a high-temperature resistant protective cover on the outside of the dual-spectrum camera 5. This high-temperature resistant protective cover adopts a ceramic fiber or water-cooled sandwich structure, so that the temperature inside the cover can be maintained within the operating range of the camera, ensuring the normal function of the dual-spectrum camera 5.

[0022] In actual use, a single camera may obstruct the view of the billet due to the roller conveyor support or the steel transfer machine column. A dual-center-point layout ensures full-surface scanning. Therefore, it is preferable that at least two dual-spectrum cameras 5 are located at the center points above the sides of the post-cutting conveyor roller 1 and the steel transfer machine 2, respectively, and both are configured to cover and capture all billets 3 on the post-cutting conveyor roller 1 and the steel transfer machine 2. With this configuration, even if one camera is briefly obstructed by steam / dust, data from the other camera can maintain system operation.

[0023] In this embodiment, preferably, the post-cutting conveyor roller conveyor 1 includes parallel double-line conveyor roller conveyors, with each conveyor roller conveyor and the steel transfer machine 2 connected in a one-to-one correspondence. The double-line conveyor roller conveyor can further improve work efficiency and also allows for one-to-one backup operation as needed. Furthermore, the one-to-one correspondence between each conveyor roller conveyor and the steel transfer machine 2, with an independent steel transfer machine at the end of each roller conveyor, avoids the mechanical complexity and failure risks caused by a single steel transfer machine operating across lines.

[0024] In this embodiment, preferably, the fixed marking unit is a marking robot 6, and a collection roller 7 is connected between the marking robot 6 and the steel transfer machine 2. The collection roller 7 is configured to collect the billet 3 loaded and unloaded by the steel transfer machine 2 and transport it to the marking area of ​​the marking robot 6.

[0025] Furthermore, the preferred device for rapidly identifying the flow order of cast billets also includes an infrared sensor for detecting the position and temperature of the high-temperature cast billet 3. The infrared sensor is configured to cooperate with a dual-spectrum camera 5 to trigger information capture when each cast billet 3 leaves the flow order roller. Thus, the infrared sensor determines that the cast billet has left the flow order roller as the trigger, the high-temperature camera identifies each cast billet, and generates a number (containing flow order information). This information moves with the lateral movement of the cast billet, and the relevant data is transmitted to a computer. After processing by image recognition software, the data is displayed in real time, and simultaneously sent to a marking robot. When the cast billet enters the collection area after leaving the cooling bed, the robot marks the flow order based on the identification signal.

[0026] In one specific implementation, during the information capture stage, the billet passes through the exit roller conveyor, and a camera captures the billet's exit position coordinates. The system automatically binds the flow sequence information (e.g., "Bill L1-001 → Flow Sequence 1, First Batch"). During the data transmission stage, the flow sequence data is sent to the collection area server via the industrial ring network and displayed on a large screen on-site. Finally, during the marking execution stage, the billet enters the collection roller conveyor, and the robot marks "L1-001" according to the binding information. This avoids the need for automatic start-stop of each transport roller conveyor and converts a mobile robot into a fixed robot, improving the robot's working efficiency.

[0027] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including combinations of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
