Currently, the most common applications are: AGV handling robot or AGV car. Its main function is focused on automatic logistics transportation. AGV handling robot automatically transports items to designated locations through special landmark navigation. The most common guidance The methods are magnetic stripe guidance and laser guidance; currently the most advanced and most scalable is the ultra-high frequency RFID guidance developed by Mikrimei Technology. The magnetic stripe guidance method is commonly used and the lowest cost method, but the site setting has certain limitations and has a certain impact on the site decoration style; laser guidance is the most expensive and has relatively high site requirements, so it is generally not used; RFID guidance cost Moderate, its advantages are high guidance accuracy, more convenient site setting to meet the most complex site layout, and no impact on the overall decoration environment of the place. Secondly, RFID's high security and stability are also not available in magnetic stripe navigation and laser navigation methods. Guidance method: Electromagnetic induction: This is our most common magnetic stripe navigation. By sticking magnetic tape on the ground, when the AGV automatic transport vehicle passes by, an electromagnetic sensor installed at the bottom of the vehicle will sense the magnetic stripe landmarks on the ground and realize automatic driving. For transporting goods, site definition depends on the different permutations and combinations of magnetic stripe polarities.

Laser induction type: The laser scanner identifies several fixed marks set within its activity range to determine its coordinate position, thereby guiding the AGV to operate.

RFID induction type: The coordinate position is automatically detected through RFID tags and reading equipment to realize automatic operation of the AGV car. Site definition is arbitrarily defined through chip tags, and even the most complex site settings can be easily completed.

Advantages: With the gradual development of factory automation, computer integrated manufacturing system technology, and the widespread application of flexible manufacturing systems and automated three-dimensional warehouses, AGV serves as a link and adjustment for discrete logistics management systems to make their operations continuous. The necessary automated handling and loading methods have developed rapidly in terms of application scope and technical level. The following is an introduction to the advantages of AGV: 1. High degree of automation - controlled by computers, electronic control equipment, magnetic induction SENSOR, laser reflection panels, etc. When auxiliary materials are needed in a certain link in the workshop, the staff inputs relevant information into the computer terminal, and the computer terminal transmits the information to the central control room. Professional technicians issue instructions to the computer. With the cooperation of electronic control equipment, this The instruction is finally accepted and executed by the AGV - delivering the excipients to the corresponding location. 2. Charging automation - when the power of the AGV car is about to run out, it will send a request instruction to the system to request charging (generally the technician will set a value in advance), and will automatically go to the charging place to "queue" after the system allows it. "Charge. In addition, the battery life of the AGV car is very long (more than 2 years) and can work for about 4 hours every 15 minutes of charging. 3. Beautiful—increase the viewing angle, thus improving the image of the company. 4. Safety - the driving path of a human-driven vehicle cannot be determined with certainty.

The guidance path of the AGV is very clear, thus greatly improving safety; 5. Cost control - the capital investment in the AGV system is short-term, while employee wages are long-term and will continue to increase with inflation. increase; 6. Easy maintenance - infrared sensors and mechanical anti-collision can ensure that the AGV avoids collisions and reduces the failure rate; 7. Predictability - the AGV will automatically stop when encountering obstacles on the driving path, while human driving Vehicles may have biased judgments due to human thinking factors; 8. Reduce product damage-can reduce cargo damage caused by manual irregular operations; 9. Improve logistics management-due to the inherent intelligent control of the AGV system, It can make the goods more orderly and the workshop tidier; 10. Smaller site requirements - AGV requires much narrower lane width than traditional forklifts. At the same time, free-running AGVs can also accurately load and unload goods from conveyor belts and other mobile equipment; 11. Flexibility - the AGV system allows for maximum changes in path planning; 12. Scheduling capabilities - due to the AGV system's Reliability makes the AGV system have very optimized scheduling capabilities; 13. Process flow - the AGV system should and must be part of the process flow, it is the link that connects many processes together; 14. Long-distance transportation ——The AGV system can effectively carry out point-to-point transportation, especially suitable for long-distance transportation (more than 60 meters); 15. Special working environment—the dedicated system can work in environments that are inconvenient for personnel to enter. Scope of application: Manufacturing industry: AGV handling robots on the market are mainly used in material handling in the manufacturing industry. AGV is used in the manufacturing industry to complete material handling tasks efficiently, accurately and flexibly. And multiple AGVs can form a flexible logistics handling system. The handling route can be adjusted in time with the adjustment of the production process, allowing a production line to produce more than a dozen products, which greatly improves the flexibility of production and the competitiveness of the enterprise. As a basic transportation tool, AGV has been applied in many industries such as mechanical processing, home appliance production, microelectronics manufacturing, and cigarettes. The production and processing field has become the most widely used field of AGV. Special industries: In the military, other detection and disassembly equipment are integrated based on the autonomous driving of AGV, which can be used for battlefield demining and position reconnaissance. The British military is developing MINDER Ree, a reconnaissance vehicle with mine detection, destruction and route verification capabilities. A capable autonomous reconnaissance vehicle. In steel plants, AGVs are used to transport furnace materials, reducing the labor intensity of workers. In nuclear power plants and places that use nuclear radiation for preservation and storage, AGVs are used to transport items to avoid dangerous radiation. In film and film warehouses, AGVs can accurately and reliably transport materials and semi-finished products in dark environments. The AGV handling robot developed by Mikelimei has been put into actual use in weapon maintenance and mining. Catering service industry: In the future, AGV vehicles are also expected to show their talents in the service industry. Basic tasks such as serving dishes and tea in restaurants can be performed by AGV handling robots. Food and pharmaceutical industry: In pharmaceutical, food, chemical and other industries that have special requirements for handling operations such as cleanliness, safety, and no emission of pollution, the application of AGV has also received attention. Many domestic cigarette companies, such as Qingdao Yizhong Group, Yuxi Hongta Group, Honghe Cigarette Factory, and Huaiyin Cigarette Factory, use laser-guided AGVs to complete the handling of palletized goods. Safety considerations for AGV Safety issues must be considered before the AGV system is installed. There are two goals. One is to prevent collisions between vehicles or between vehicles and people. The second is that when the anti-collision system fails, the main safety equipment must immediately stop the vehicle and wait for manual intervention to resume. Security systems must be in place early in the system installation. Security equipment can be divided into fixed equipment and mobile equipment. Fixed equipment usually constitutes what are called system-level components. Includes blocking systems, and equipment layout. Mobile equipment, including vehicles, must follow a series of rules, such as load capacity, center of gravity, vehicle speed, etc. Before using the AGV system, users must be trained on the use of the safety system. There are many types of traffic control and anti-collision systems. The simplest is to install anti-collision buffer strips in front of the vehicle and keep the vehicle speed below a certain value. Once it hits the vehicle, the vehicle will stop until the resistance disappears. The other is area blocking, which separates different areas on the guide rail. Vehicles can only enter this area when there is no vehicle in the next area. The vehicle sensor is detected by a ground induction coil under the guide rail.

This method usually uses a programmable controller to implement relevant logic control. More advanced is computer zone blocking, which is similar to zone blocking but more complex. Computers monitor the positions of all vehicles and monitor the gaps between them. The layout of the workshop should consider the width of the vehicle channel, the distance from the pedestrian channel, the distance to the equipment in the workshop, etc. Vehicle detection should include speed detection, load detection, and injury prevention. Relevant optical sensing and ultrasonic sensors can be used to detect the distance between vehicles. As people's requirements for production efficiency increase, the demand for AGVs is also increasing, and AGV technology will be more and more widely used.
