In a cassette tape feeder (5) for positioning SMD electronic elements or components placed on a carrier tape (50) with holes (51) and covered with a cover tape (55) and comprising a body (10), a drive (40) for feeding the carrier tape using a toothed wheel (45) engaging with the holes (51) of the carrier tape (50) and seated on the body (10), a drive (60) for removing the cover tape using a reel (66) for collecting the cover tape, a carrier tape and cover tape reel (80) rotationally seated on the body (10) and a carrier tape and cover tape guide located above the toothed wheel (45) of the drive (40) for displacement of the carrier tape engaging with the holes of the carrier tape, the carrier tape and cover tape guide (30, 130) is one among a set of carrier tape and cover tape guides (30, 130) selected to dimensions of the cover tape and the carrier tape, on which the SMD electronic components (1) are placed and fed, while each of the carrier tape guides (30, 130) has the same installation component (31, 131) with dimensions adapted to the dimensions of a socket (15) on the body (10) and is replaceably mounted to the body (10) of the cassette tape feeder (5) and comprises a strip (39, 139) guiding the carrier tape (50) with longitudinal side protrusions, which are located parallel to each other and spaced from each other no less than a carrier tape (50) and cover tape (55) width, while, within an area of one strip (39, 139) end, there is the pivotally attached flap (35, 135) of the carrier tape (50) guide, pressed to the strip (39, 139) of the carrier tape (50) guide by means of a spring (16). |
