Robot wireless charging alignment method and system

The invention relates to a robot wireless charging alignment method and system. The method comprises the following steps: transmitting an automatic return charging signal to a vehicle control unit when a charging management unit detects that the electric quantity of a power battery is less than a preset value; enabling the vehicle control unit to control the robot to return to a preset wireless charging position; recognizing the outline of a wireless charging base, and moving the wireless charging base to the position above the wireless charging base; receiving an infrared signal sent by an infrared alignment lamp group; judging whether the percentage of the signal area of the received infrared signal sent by the infrared alignment lamp group is greater than a preset proportion or not; if so, controlling the robot to be aligned again; if so, judging that whether the detected charging current of the wireless charging transmitting coil is larger than preset current or not; if so, performing wireless charging; a
