  • Patent number: 6877541
    Abstract: Disclosed herein is a tape feeder for chip mounters. The tape feeder is constructed so that front and rear locators are restrained by a restraint slot of a cam slider moving horizontally, and bearings of the front and rear locators alternatively execute vertical and horizontal movements while sliding along the restraint slot by a reciprocating motion of a cam slider, thus repeatedly moving a carrier tape backward while locking the carrier tape and moving the carrier tape forward while releasing the carrier tape, therefore allowing the carrier tape to be fed precisely. The tape feeder allows the carrier tape to be fed precisely, and prevents chips from being turned over and removed from the carrier tape when a vinyl cover is discharged, thus minimizing a malfunction of the chip mounter during an operation of the chips and thereby maximizing operational reliability. Further, the tape feeder allows the number of elements to be reduced, in addition to achieving a slim construction.
