Description

Technical Field

[0001] This invention relates to the field of waste material processing, and in particular to a visual recognition and reuse system and method for waste materials of steel plates used in power transmission towers. Background Technology

[0002] Power transmission towers are core infrastructure for power grid construction. Their main structure is primarily made of Q235B and Q355B carbon steel, with a small amount of 304 stainless steel plates, processed through laser cutting, bending, and welding. During the production of power transmission towers, to meet the processing requirements of flanges, connecting plates, reinforcing ribs, hanging plates, crossarms, and other parts of different specifications, whole plates need to be cut into shapes. This inevitably generates a large amount of irregularly shaped and differently sized scrap material. Currently, the power transmission tower industry mainly uses the following methods to handle this scrap material: Directly selling scrap materials, manual layout and reprocessing, and secondary processing by punching machines are some of the methods used by some companies. Some companies have also started to use cameras or mobile phones to take pictures and identify the outline of scrap materials, but there are obvious limitations. Not only is the scanning range limited, but each scrap material needs to be processed individually, and the angle and position of the scrap material need to be adjusted manually. The operation is cumbersome, costly, and inefficient. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a visual recognition and reuse system and method for surplus steel plates used in power transmission towers that is easy to operate, effectively reduces costs, and is more efficient.

[0004] To achieve the above objectives, the present invention provides a method for visual recognition and reuse of scrap steel plates used in power transmission towers, comprising a host, a contour scanner, a laser cutting head, and a processing table. The processing table is used to place scrap steel plates. The contour scanner and the laser cutting head are both connected to the host via signal, and the contour scanner and the laser cutting head are both movably mounted on the processing table.

[0005] The advantages of adopting the above technical solution are: by connecting the contour scanner and laser cutting head to the host signal and setting them to move on the processing table, the contour scanner and laser cutting head can identify and cut the leftover material on the processing table, replacing the inefficient mode of traditional manual measurement, hand-drawing contours and manual layout. It can automatically complete the acquisition and cutting of leftover material contours, making the operation more systematic and convenient, and effectively reducing costs and increasing processing efficiency.

[0006] The present invention can be further configured such that: a guide rail and a movable frame are provided on the processing table, the guide rails are respectively provided on both sides of the processing table in the horizontal direction and extend in the vertical direction, the movable frame extends in the horizontal direction and can slide along the guide rail in the vertical direction, and the laser cutting head and the contour scanner are both provided on the movable frame.

[0007] By further configuring the equipment, longitudinal guide rails are installed on both sides of the processing table, and a transverse movable frame that can slide along the guide rails is configured. The laser cutting head and the contour scanner are placed together on the movable frame, allowing scanning and cutting to share the same motion system. This simplifies the overall structure of the equipment, reduces manufacturing costs, ensures the consistency between the scanning coordinate system and the cutting coordinate system, eliminates errors, and significantly improves the positional accuracy of plate scrap identification and cutting.

[0008] The present invention can be further configured such that the laser cutting head can be slidably arranged along the movable frame, and the contour scanner is arranged on one side of the laser cutting head.

[0009] By further configuring the profile scanner to one side of the horizontally sliding laser cutting head, the scanner can synchronously complete the full-range horizontal and vertical movement with the cutting head. Scanning and cutting share the same motion reference, eliminating the need for a separate scanning drive mechanism, thus simplifying the equipment structure and improving operational stability.

[0010] The present invention can be further configured to include a protective cabin covering the outside of the processing table, wherein multiple cameras are installed in the protective cabin.

[0011] By further configuring the equipment, a fully enclosed protective chamber is installed on the outside of the processing table and equipped with multiple cameras. This effectively isolates the sparks, smoke, slag and noise generated during laser cutting, preventing them from harming the workshop environment and operators. On the other hand, the multiple cameras can monitor the cutting area, allowing operators to effectively grasp the processing status and improve the safety and controllability of the production process.

[0012] The present invention can be further configured to include an operating table located outside the protective cabin, the main unit being disposed at the operating table, and the protective cabin also having a display screen connected to the camera signal near the operating table.

[0013] By further reconfiguring the system, the control panel is placed outside the protective cabin and equipped with a display screen connected to the camera. Operators can monitor and operate the equipment from outside the cabin, completely avoiding the risks of contact with laser radiation, high-temperature molten slag, and moving parts. At the same time, the main unit is integrated into the control panel, which facilitates equipment maintenance and management and ensures production safety.

[0014] The present invention can be further configured such that: the protective chamber includes a feeding belt located below the processing table, the processing table includes a plurality of mesh holes, the mesh holes are connected to the feeding belt, and the feeding belt can send the waste generated after the processing of the board material out of the protective chamber.

[0015] By further configuring the equipment with a mesh on the processing table and a feeding belt underneath, cutting waste can be automatically discharged, eliminating the need for regular manual cleaning of residue. This also avoids the problems of uneven placement of leftover material and reduced cutting accuracy caused by the accumulation of cutting residue on the table. At the same time, the feeding belt directly delivers the waste outside the protective chamber without the need to stop the machine for cleaning, thus improving the effective utilization rate of the equipment.

[0016] To achieve the above objectives, the present invention provides a method for visual identification and reuse of surplus steel plates used in power transmission towers based on the system of claim 1, comprising the following steps: Step 1: Place the cleaned leftover board material on the processing table at intervals; Step 2: The host computer of the operating table starts the self-test program, verifies the communication and operating status of each component in turn, and calibrates the coordinate system of the machining table. Step 3: The movable frame moves at a constant speed along the longitudinal guide rails on both sides of the processing table. The laser cutting head moves synchronously back and forth along the transverse side of the movable frame, driving the contour scanner fixed on one side to perform a grid-like full-coverage scan of the entire processing table. After the scan is completed, the movable frame automatically returns to the origin of the processing table. Step 4: The host computer preprocesses the acquired image data, imports the drawings of the power tower parts to be processed, and then performs layout. Step 5: The host sends a cutting command to the laser cutting head, and the movable frame and the laser cutting head move together according to the generated cutting path; Step 6: After the cutting is completed, the movable frame and the laser cutting head will automatically return to the origin.

[0017] Furthermore, in step five, multiple cameras inside the protective cabin capture images of the cutting area in real time and transmit them to the display screen on the control panel for synchronous display.

[0018] Furthermore, in step five, the mesh of the processing table allows the molten slag and waste generated during cutting to fall onto the feed belt below. The feed belt runs continuously at a low speed, automatically sending the waste out of the protective chamber.

[0019] The advantages of adopting the above technical solution are: through the steps of leftover material placement, system self-inspection and calibration, full-area scanning, intelligent layout, and automatic cutting, the entire process from calculating the leftover material of the board to processing and unloading is realized without human intervention. It is equipped with real-time monitoring of the cutting process by multiple cameras and synchronous automatic slag removal function, eliminating the need for manual measurement of dimensions, drawing of outlines, and manual layout for processing leftover material of the board, improving the utilization rate of materials, significantly reducing costs, and ensuring that scanning and cutting share the same motion system, which ensures the consistency of the scanning coordinate system and the cutting coordinate system, reduces errors, and has a higher accuracy rate than manual operation.
