Abstract

An automatic charging system of a robot cleaner includes: a rotating plate (306) installed at a robot cleaner; an infrared ray receiving unit (304,305) mounted at the rotating plate (306) and receiving an infrared signal generated from a power supply unit (400) while being rotated; a microcomputer (303) for moving the robot cleaner to the power supply unit (400) on the basis of the received infrared signal; and an ultrasonic generator (308) for generating a stop signal when the robot cleaner nears to the power supply unit (400). A robot cleaner can be accurately and quickly moved to a power supply unit for a rapid charging operation, and a cost for implementing the robot cleaner can be reduced.

Description

technical field [0001] The present invention relates to a cleaning robot, in particular to an automatic charging system and method for a cleaning robot. Background technique [0002] figure 1 It is a schematic block diagram showing the structure of the charging system of the cleaning robot according to the prior art. [0003] Such as figure 1 As shown, the charging system of the cleaning robot (not shown) includes a cleaning robot power receiving unit 100 and a cleaning robot power supply unit 200 for charging the battery 101 . [0004] The power supply unit 200 includes an infrared sensor 201 for communicating with the cleaning robot, and a charging part 202 for charging the battery 101 of the cleaning robot. The infrared sensor 201 is installed at the charging part 202, and generates an infrared signal in a predetermined direction. [0005] The power receiving unit 100 of the cleaning robot includes: a battery 101; a remaining battery capacity detector 102 for detectin...
