AGV design concept

Date: 2019-03-06 11:32    Clicks:     Autor: IKVROBOT    

It provides a broad space for the research and application of AGV. AGV is gradually used in various industries such as automobile, tobacco, logistics, etc. Especially in the automated logistics warehouse, AGV plays an increasingly important role.

In modern logistics equipment, logistics handling AGV has become an indispensable and important tool, which has the advantages of being intelligent and flexible, which can greatly improve work efficiency. Specifically, the logistics handling AGV mainly has the following characteristics: First, the logistics handling AGV can specify the type of work, can ensure the reliability of repeated work, and greatly improve the efficiency of work. Second, the logistics handling AGV is convenient to guide and can better promote the adjustment of functions, which is conducive to the re-arrangement of the overall workshop environment. Third, the logistics handling AGV can automatically transport the goods to a designated location, greatly saving manpower and material resources. Fourth, the logistics handling AGV can better match the automatic conveying line in the automatic warehouse system to realize the automatic loading and unloading of goods. Fifth, the power supply for the logistics handling AGV is a DC battery, which has low noise pollution and can effectively improve the working environment.

Sensor Technology

To monitor and feedback the current position, speed and driving attitude of the AGV car, the AGV car can work normally and stably, and the detailed status information of the AGV car is fed back to the controller, and the upper position is completed according to the specific situation. Machine operating instructions. The necessary condition for ensuring the normal operation and safe operation of the AGV car is to implement effective internal and external environmental conditions. The emergence and development of intelligent sensors further enhances the intelligence of the AGV. At present, intelligent sensors are mainly divided into two types, internal and external. The internal intelligent sensors are mainly used to control and monitor the AGV itself. The external sensors are mainly used to sense various external environmental information and are installed on the AGV trolley.

Intelligent control technology

ntelligent control mainly refers to an automatic control technology that autonomously drives intelligent machines to achieve control objectives. With the development and penetration of computer information technology and other technologies, control technology has been deeply researched and developed, and control systems have developed into intelligent systems. An inevitable trend. The emergence of intelligent control technology is mainly to solve the control problems that are difficult to solve by traditional methods. Today, it mainly uses knowledge-based intelligent control, fuzzy control, artificial intelligence control, neural network control and other relatively mature control methods. Network control and fuzzy control are applied to the field of robot control.

DC power technology

The AGV must have sufficient power to work properly. At present, the main power supply modes of the AGV are divided into wireless and wired. The wired power supply mode restricts the autonomy and the range of the AGV. Therefore, the wireless power supply mode is adopted, mainly including Carrying the two supply solutions of the engine and the DC battery on the vehicle body, however, these two methods have certain defects, which restrict the operation time of the AGV in the work and affect the durability and reliability of the system. Therefore, the reliability and efficiency of the AGV energy supply should be improved to ensure the smooth and efficient operation of the AGV trolley. DC power supply technology is the bottleneck of AGV car development. The time required for AGV to work generally lasts for about eight hours. For a long time, it is necessary to find a battery with large capacity to meet long-term discharge. The ideal battery should have a very high battery. The energy density needs to be characterized by high temperature resistance, low cost, and rapid discharge and charging.

AGV performance parameters

The AGV is mainly composed of a vehicle body, an on-board controller, a battery, a communication device, etc. The mechanical system is the basis of the entire AGV, and all other devices are loaded. The rationality of mechanical system design determines the performance of AGV.

Design and implementation of AGV mechanical system

The structure of the car body. The structure of the AGV trolley mainly includes three aspects: steering form, drive form and number of axles. The single-drive form structure is mostly used for the three-wheeled vehicle body structure. This type of vehicle structure can realize the left and right turning, forward and backward of the trolley. The structure has low requirements on the ground and good grip, and is mostly used for small AGV. The differential drive body consists of a four-wheel model and a three-wheeled model that enables the car to turn left and right, forward and reverse, and spin in place. The car is turned compared to the single-drive version. The effect is better. The four-wheel model has higher requirements on the flatness of the ground, and the adaptability of the Xiang is relatively poor, which is not suitable for outdoor work. The double-drive form is more common in four-wheel models. Its main advantage is that it can better control the body changes during the movement. It can be used in special working environments. The main disadvantage is that the car has poor adaptability and relatively high cost. . The multi-wheel drive type is mostly used in the eight-wheel model. The structure of the vehicle is complex, costly and difficult to control, and is often used in the heavy-duty industry.

Drive motor selection

AGVs need to be flexible, free and adaptable. Therefore, battery power is generally used, and DC motors are often used. DC motors are generally classified into DC printed motors, small inertia DC motors, wide speed DC motors, and cup rotor DC motors.

The AGV trolley is an embodiment of automation and automation of logistics warehouses, making automation of the entire automated warehouse. At present, AGV technology is mainly based on indoor applications, and will gradually develop into outdoor or semi-outdoor according to the development needs of the market and industry in the future. In today's society where new technologies and new equipment are increasingly updated, AGV will have a broader development space and platform. Welcome to consult AGV industrial robots.
