AGV station arrival positioning device and method thereof

Abstract

The invention discloses an accurately-positioned AGV station arrival positioning device, which is made by adopting the above technical scheme. The device has the advantages that the AGV positioning repeatability precision can be improved within +/-1 mm from normal +/-5 mm finally, and the AGV carrying a manipulator for production operation becomes a reality. Through the technology, the AGV plus vision plus a robot plus a scheduling system plus precise positioning is a robot which can replace a human completely. The AGV has the brain (the scheduling system), the eyes (the vision), the feet (theAGV body) and the hand (the manipulator) and can do fine work, and thus, the AGV can be applicable to various situations, and major problems in practical applications of the robot can be solved.

Description

technical field [0001] The invention relates to the field of automation control, in particular to an AGV arrival positioning device. Background technique [0002] At present, the commonly used AGV arrival methods are: stop when the magnetic strip sensor detects a magnetic change, stop by matching the RFID station number, stop by photoelectric positioning, stop by running distance, stop by running time, etc.; these methods are all adopted Ordinary AGV stopping methods, the stopping accuracy of these stopping methods is generally between ±5mm and ±10mm, but if the AGV needs to coordinate with the equipment on the platform after stopping, such as through the AGV car The mechanical arm performs material assembly, screwing, and pick-and-place materials for precision workpieces. This kind of ordinary stop accuracy cannot be achieved. Therefore, precise stop determines the wide application of AGV+ robots, and determines whether the robot can completely replace humans. key issues. ...
