[0001] The invention relates to the technical field of metal ingot cuttings, in particular to a metal ingot cutting production process. Background Art

[0002] The traditional metal ingot processing industry faces problems such as low production efficiency, high labor intensity and many safety hazards, especially in the key links such as metal ingot handling, destacking, chip cutting, screening and packaging, which rely on a lot of manual operations, which not only leads to high production costs, but also affects processing accuracy and product consistency. With the rapid development of automation and intelligent technology, the industry urgently needs to introduce advanced equipment and technology to achieve efficient, safe and refined production processes. Summary of the invention

[0003] In order to solve the above technical problems, the present invention specifically adopts the following technical solutions.

[0004] Design a metal ingot chip production process, including the following steps:

[0005] S1, AGV transportation: First, use the AGV transporter to fork out the metal ingot stack from the material collection point and place it at the designated position of the robot arm;

[0006] S2, robotic arm depalletizing: After the AGV transporter places the material at the robotic arm position, the 3D camera automatically identifies the position height and front and back sides of the metal ingot, sends the coordinates, and guides the robotic arm to grab it. The robotic arm will flip the inverted metal ingot and place it at the specified position of the conveyor to complete the action;

[0007] S3, metal ingot chipping: the metal ingot feeding conveyor conveys the metal ingot to the chip cutter for chip processing. The metal ingot chip cutter automatically works to push the metal ingot to the knife roller for chipping. The chip cutter removes metal from the cross section of the metal ingot to produce the required shape and size. The remaining material head automatically falls into the metal ingot head conveyor 3, and is transported to the designated location by the metal ingot head conveyor 3 for collection;

[0008] S4, collection and screening: The materials are collected by the cyclone separator through the pipeline wind speed, and put into the screening device for classification, and are divided into finished products, upper finished products, and lower finished products; the finished products are sent to the cyclone separator through the pipeline and put into the secondary screening device again, and enter the packaging process; the upper finished products and the lower finished products are collected by the vacuum conveyor or cyclone separator, and enter the packaging process or collected for recycling;

[0009] S5, packaging process: the finished materials enter into bulk bags or balers after screening.

[0010] Preferably, in step S1, the AGV transporter needs to be equipped with a material picking point, a pallet stacker, and a charging station. When the metal ingots are grabbed, the AGV receives a signal, forks out the metal ingot pallet and places it on the pallet stacker. After a certain number of layers are placed, the pallet is moved to a designated position.

[0011] Preferably, in step S2, when the robot arm depalletizes, the robot arm needs to be equipped with a 3D recognition camera and a safety grating, and the safety grating can completely cover the range of the 3D camera and the robot arm.

[0012] Preferably, in step S3, a chip breaker is connected to the outlet of the chip cutter, and the metal chips are processed into long strips and discharged from the outlet of the chip cutter. During chip breaking, the long strips of metal chips are processed into irregular short chips within a certain range.

[0013] Preferably, in step S4, a wet dust collector is provided at the rear end of the cyclone separator, and the wet dust collector provides negative pressure fan suction to reduce contact and collision between materials and equipment, thereby reducing the risk of ignition of flammable dust.

[0014] Preferably, a vibrating screen is provided below the cyclone separator to screen out the finished material.

[0015] The beneficial effects of the present invention are:

[0016] 1. The present invention integrates AGV automatic transport vehicles, robotic arm depalletizing systems and highly automated production lines, significantly reducing dependence on manual labor, reducing labor intensity, and improving production efficiency and safety. It also uses 3D visual recognition and precision robotic arms to work together to achieve precise positioning and processing of metal ingots, reduce human errors, and improve product dimensional accuracy and surface quality.

[0017] 2. The production line configuration can be adjusted according to the different materials and sizes of metal ingots, supporting diversified product processing needs and enhancing the flexibility and market adaptability of the production system. The introduction of safety measures such as safety gratings and obstacle avoidance radars effectively avoids safety accidents during operations. The application of wet dust collectors reduces dust pollution and fire risks, meeting the environmental protection and safety production standards of modern factories.

[0018] 3. The entire production process is centrally controlled by a central computer, which enables real-time monitoring and analysis of data, facilitates production scheduling and efficiency optimization, and promotes the company's transformation to intelligent manufacturing.

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] Example 1

[0025] A metal ingot chip production process includes the following steps: S1, AGV transportation: first, the metal ingot stack is forked out from the material collection point by an AGV transport vehicle and placed at the designated position of the mechanical arm 4; the AGV transport vehicle is equipped with an electromagnetic or optical automatic guidance device, which can travel along a specified guidance path and has safety protection and various transfer functions. The AGV transport vehicle can automatically complete the whole process of picking up and placing goods and horizontal operation under the command of the control system.

[0026] The AGV transporter needs to be equipped with a material collection point, a stacking machine, and a charging station. When the metal ingots are grabbed, the AGV receives a signal, forks out the metal ingot pallet and places it on the stacking machine. After placing it to a certain number of layers, the pallet is moved to the designated location. When the power is insufficient, the AGV will automatically go to the designated location to charge.

[0027] Under computer monitoring, the AGV function moves and stops at the designated location accurately according to the path planning and operation requirements to complete a series of operation functions. The automatic handling and sorting mode, through the combination with WMS and MES, AGV realizes the automatic handling management of warehousing and the flexible dynamic allocation of cargo positions; picking changes from "people to goods" to "goods to people" to improve work efficiency and reduce labor intensity. System trend, in the context of Industry 4.0, by introducing the AGV dynamic system and changing the existing manual handling mode, the automation of handling logistics can be effectively realized.

[0028] The AGV truck has dual obstacle avoidance radars embedded on both sides of the frame, an optional rear-facing radar to provide 360° protection, and an optional Mid360 installed on the gantry end to identify pallets in three dimensions for more accurate picking.

[0029] S2, robot arm depalletizing: After the AGV transporter places the material at the robot arm point, the 3D camera automatically identifies the position height and front and back of the metal ingot, sends the coordinates, and guides the robot arm 4 to grab it. The robot arm 4 will flip the reversed metal ingot and place the metal ingot at the specified position of the conveyor to complete the action. Among them, two sets of chip cutting machines 5 use a set of robot arm depalletizing devices. After the metal ingot stack is grabbed, the 3D vision recognizes that the material is grabbed, sends a signal, and the AGV automatically changes the material; when the robot arm depalletizes, the robot arm 4 needs to be equipped with a 3D recognition camera and a safety grating, and the safety grating can completely cover the range of the 3D camera and the robot arm 4, and personnel are prohibited from entering. When a person enters the grating, the equipment automatically stops to protect the safety of the personnel. The robot arm can perform repetitive actions and can efficiently complete a large number of repetitive tasks. The robot arm can effectively improve production efficiency and can replace manpower to complete a large number of repetitive tasks. The robot arm can operate under harsh environmental conditions and can replace manual labor to operate in harsh AGV environments. It greatly improves the accuracy of positioning and operation, reduces errors and improves product quality. Secondly, the visual positioning guidance system is highly flexible and can adapt to different working environments and task requirements.

[0030] S3, metal ingot chipping: the metal ingot feeding conveyor 17 conveys the metal ingot to the chip cutter 5 for chip processing. The metal ingot chip cutter 5 automatically works to push the metal ingot to the cutter roller for chipping. The chip cutter removes metal from the cross section of the metal ingot to produce the required shape and size. The remaining material head automatically falls into the metal ingot head conveyor 33 and is transported by the metal ingot head conveyor 3 to a designated location for collection (such as a waste recycling area);

[0031] Conveyors can continuously transfer goods within a section, with very low cost, relatively accurate time and stable cargo flow. Therefore, they are widely used in modern logistics systems. The entire handling system is controlled by a central computer, forming a complete set of complex cargo transportation and handling systems. The in and out storage, loading and unloading, classification, sorting, identification, and measurement of a large number of goods or materials are all completed by the conveyor system. In modern cargo handling systems, conveyors play an important role.

[0032] If chip breaking is required, a chip breaker 6 is connected to the outlet of the chip cutter 5, and the metal chips are processed into long strips and discharged from the outlet of the chip cutter 5. During chip breaking, the long strips of metal chips are processed into irregular short chips within a certain range.

[0033] S4, collection and screening: The materials are collected by the cyclone separator 12 through the pipeline wind speed, and are put into the screening device 16 for classification and treatment, and are divided into finished products, finished products on the bottom, and finished products off; a vibrating screen is set below the cyclone separator 12 to screen out the finished materials, and the finished products are sent to the cyclone separator 12 through the pipeline and then put into the secondary screening device 16 again to enter the packaging process; the screening device is a multi-layer linear vibrating screen that uses an upper vibration motor to vibrate, and the finished products on the top and the finished products on the bottom are collected by the vacuum conveyor 13 and enter the packaging process or collected for recycling; a wet dust collector 15 is set at the rear end of the cyclone separator 12, and the wet dust collector 15 provides negative pressure fan pumping to reduce the contact and collision between the materials and the equipment, and reduce the risk of ignition of combustible dust. Positive pressure fans can be used for processing non-flammable metals.

[0034] S5, packaging process: the finished materials enter into bulk bags or balers after screening.

[0035] AGV transport stage of the present invention: the AGV transporter automatically transports the metal ingot stack to the designated position of the robotic arm according to the preset path, and ensures driving safety and accuracy through electromagnetic or optical guidance technology. It automatically charges when the power is insufficient to ensure uninterrupted operation. The 3D camera identifies the position and posture of the metal ingot, guides the robotic arm to accurately grab and flip the metal ingot, and places it on the conveyor. The safety grating ensures the safety of personnel during the operation and prevents accidental injuries. The robotic arm destacking stage: the 3D camera identifies the position and posture of the metal ingot, guides the robotic arm to accurately grab and flip the metal ingot, and places it on the conveyor. The safety grating ensures the safety of personnel during the operation and prevents accidental injuries. Metal ingot chip cutting stage: the metal ingot is transported to the chip cutter via the conveyor, and the chip is cut by the knife roller to produce metal chips of the required size, and the remaining material is automatically collected. If necessary, the chip breaker is connected for further processing. Collection and screening stage: the metal chips after chipping are transported to the cyclone separator and vibrating screen for classification through the pipeline wind power to distinguish the finished product grade, and the wet dust collector is used to treat the environment to improve the safety of the operation. Packaging stage: The finished products after screening are sent to the baler or ton bag for packaging, completing the automated production process, which provides convenience for subsequent storage, transportation or reprocessing. The production line process realizes the automation of the entire chain from raw material handling to finished product packaging, which not only greatly improves production efficiency and quality control capabilities, but also provides an example of the transformation to intelligence for the metal processing industry.

[0036] The present invention adopts AGV transportation, robot arm destacking, conveyor transportation, chip cutter, chip breaker, collection and screening, packaging and other processes, which can reduce the number of personnel and labor intensity during chip production, and greatly improve the production safety index of metal ingot processing. Metal ingots of different components and specifications can be processed into particles, chips or sheets with different lengths, widths and thicknesses. This equipment can realize the full process automation of metal ingot chip production.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
