Provided is a signal receiving device of an infrared touch frame. A sampling assembly samples current signals output by a receiving tube, an analog switch receives switch sequence signals through a control end, the analog switch is switched on after a transmitting tube of the infrared touch frame emits light through control of the switch sequence signals, and the analog switch is switched off when the transmitting tube does not emit light. When switched on, the analog switch sends the signals sampled by the sampling assembly to a blocking capacitor, and the blocking capacitor couples and filters the signals received when the analog switch is switched on and then obtains and outputs the coupling signals for analog-digital conversion processing. Due to the facts that the analog switch is in a switched-off state when the transmitting tube does not emit light and charges stored by the blocking capacitor will not be released by the sampling assembly, when analog-digital conversion processing is carried out on the coupling signals output by the blocking capacitor, the transmitting tube does not emit light continuously, the working duty ratio of the transmitting tube is reduced, and the power consumption of the infrared touch frame is lowered.
