The invention provides a receiving mechanism in detecting and screening equipment of belt electronic components, which detects an electronic component, coils the detected electronic component and realizes detection while coiling. The receiving mechanism comprises a coiling sleeve and a receiving power mechanism, wherein the coiling sleeve is used for winding electronic component belts passing through a scrap-blanking mechanism; and the receiving power mechanism is connected with the coiling sleeve to drive the coiling sleeve to unidirectionally and intermittently rotate. The receiving mechanism coils and forms belt electronic components which are fully qualified products. The electronic component belts in front of the receiving mechanism are intermittently fed so as to be consistent with the receiving mechanism, and the coiling sleeve unidirectionally and intermittently rotates to realize detection while coiling and improve the working efficiency.
