The invention provides a multifunctional automatic detecting device which comprises a base. A tested module mounting frame and a test component are arranged on the base. A detecting camera is arrangedabove a tested module. A specular reflection device which can move up and down and is used for reflecting the LED state of the side surface of the tested module to the upper detecting camera is arranged between the tested module and the detecting camera. Compared with the prior art, the multifunctional automatic detecting device provided by the invention has the advantages that an LED light stripindicating the working state of the tested module is arranged on the upper side surface of the tested module; the detecting camera which is used for detecting the LED light strip on the side surfaceof the tested module is arranged above the tested module; the specular reflection device is arranged between the tested module and the detecting camera to monitor the LED state of the side surface ofthe tested module.
