Storage and transfer robot used for modern logistics industry

Abstract

The invention relates to a storage and transfer robot used for the modern logistics industry. A chassis of a car body of the robot is connected with each device for fixing the robot; an anti-collision protective device comprises an infrared photoelectric sensor, a front cover plate, a rear cover plate and an emergency stop switch; drive wheels of a drive device are arranged at one end of a direct-current motor through a connecting shaft, and are symmetrically arranged at the two sides of the middle of the car body fixedly; driven wheels are symmetrically arranged at the two sides of the front end and the rear end of the car body, and a differential drive mode is adopted for drive control; a navigation and location unit comprises an inertial navigation sensor, a two-dimensional laser bar code scanner, a grey sensor and two-dimensional codes, wherein navigation and location are completed in a mode of adopting inertial navigation, locating with the two-dimensional codes and correcting deviation through the grey sensor; a control unit uses a control system based on a single chip microcomputer, and comprises a micro controller and a control module circuit; and a lifter is beneficial for reducing logistics cost and reducing investment of staff. The storage and transfer robot can be used for transferring goods to a designated area, and can improve sorting efficiency of modern logistics.

Description

technical field [0001] The invention belongs to the field of automatic logistics and transportation, and in particular relates to a storage and handling robot used in the modern logistics industry. Background technique [0002] The warehouse handling robot is a new type of robot (Automated Guided Vehicle) developed on the basis of traditional robots. The robot is powered by a battery and can realize autonomous navigation. It is monitored and commanded by a control center such as a PC. It runs along the calculated optimal path to the target address and completes the commands issued by the control center. Robots can save logistics handling time and reduce personnel costs. [0003] With the continuous development of computer technology and control technology, the application fields of robots are also expanding. Small robots are used in daily office transfers, medicine transfers in hospitals, and supermarket cargo delivery. In recent years, the e-commerce industry and large-sc...

Problems solved by technology

Most of the warehousing and handling robots are guided by electromagnetic guidance, light stripe guidance, tape guidance, and laser reflection positioning guidance. At the beginning, the robot used electromagnetic induction for guidance. The principle is to bury metal wires on the ground and install two metal wires on the handling robot. The induction coil made of wire, when the robot walks on the metal wire, the energized coil will generate electromagnetic induction with the guide wire on the ground, but the metal wire is not easy for the robot to turn, and it is not suitable for narrow storage environments; magnetic induction Guidance is to replace the metal wire in the electromagnetic induction guidance method with magnetic objects such as magnetic strips and magnetic nails. There are sensors on the robot that can perform magnetic induction. Guidance is achieved by receiving magnetic induction signals during walking, but it will destroy the original The working ground environment; optical guidance is to use colored paint or ribbon to lay the track, use the optical sensor to collect the image signal on the ground, and use the image processing technology to judge and identify the track to realize the guidance, although this method does not need to destroy the ground of the working environment, Only the ground surface needs to be pasted, but because the image processing requirements are high, the presence of foreign matter such as dust or liquid will reduce the processing accuracy of the image processing, so the reliability of this method is low

[0006] Existing robots generally use PLC and industrial computer as controllers, which are large in size, high in cost, weak in computing power, and difficult to achieve high-precision positioning

The existing storage and handling robots do not have the function of real-time communication with the control terminal, and cannot transmit their own motion status and information status to the control terminal through the wireless communication module.
