The invention describes a component supply apparatus for providing separated elements (195, 595a, 595b). The component supply apparatus (100, 200, 600, 700) has (a) a vibrating conveyor (122a, 122b, 122c, 622a, 622b), (b) a supply element (120, 320, 420) with a supply area, wherein the vibrating conveyor (122a, 122b, 122c, 622a, 622b) is configured to enable the supply element (120, 320, 420) to vibrate so that the separated elements (195, 595a, 595b) can be conveyed into the supply area from an upper surface of the supply element (120, 320, 420), and a camera (130, 630) which is arranged below the supply element (120, 320, 420), wherein the supply element (120, 320, 420) is optically transparent at least in the region of the supply area is, so that elements (195, 595a, 595b) which have been conveyed in the supply area can pass from the bottom of the supply element (120, 320, 420) and be detectable by the camera (130,630). Additionally, a method for providing the separated element (195, 595a, 595b) and an assembling system (750) are also described. The assembling system has the above component supply apparatus (100, 200, 600, 700).
