Intelligent charging device and charging method for sweeping robot

The invention relates to an intelligent charging device and method for a sweeping robot, and the device comprises a flat and long-strip-shaped housing which is disposed at the lowest end of an indoor wall surface. Four groups of infrared correlation units are transversely arranged on the front side surface of the shell; a long-strip-shaped transverse groove is formed in the front side surface of the shell in the length direction, a plurality of magnetic attraction charging sets are transversely arranged in the transverse groove side by side, and when the magnetic attraction charging sets and charging contacts of the sweeping robot are magnetically attracted, the magnetic attraction charging sets move forwards to be powered by magnetic attraction force and are attached to the charging contacts of the sweeping robot; by applying the method of the invention, a plurality of charging point locations can be provided, accurate alignment calculation does not need to be specially carried out, an anti-false-triggering
