SYSTEM AND METHOD OF REPLACING REEL

The present invention relates to a method for changing a reel, the method comprising the step of a tape supply station supplying tape to a coiling station via at least one bridge, wherein supplying the tape to the coiling station comprises the steps of: by pre-determining the orientation of the at least one male key element in the shaft of the coiling station before the at least one matching female key element is snugly fitted to the male key element of the shaft. to provide a predetermined reel position such that the tape from the bridge is aligned with at least one tape insertion slot on the reel.

Recently, one of the major issues faced in the semiconductor field is the failure to insert the carrier tape into the reel. The carrier tape insertion opening in the reel has a small clearance to the carrier tape being inserted. If the position or angle of the carrier tape is slightly off the opening, inserting the carrier tape into the reel will fail. The current driving force on the carrier tape is not sufficient to "self-align" and push the carrier tape into the reel opening.

U.S. Patent No. 8439292 to Ismeca discloses an apparatus for automatic coiling and/or uncoiling on a reel of a flexible tape carrier of electronic components, the apparatus comprising a coil in which the reel may be connected to a rotating actuator. a retractable tape guide comprising a ring position and articulating jaws that can be closed together to form a channel to guide the flexible tape and connect the free end of the flexible tape to the hub of the reel; , the apparatus further includes a stopper member engaging the slot in the reel hub to stop the reel in a position where the slot is aligned with the tape guide. However, this invention does not have a predetermined orientation during reel loading and cannot print a label with output information.

U.S. Patent Publication No. 4747553 to Ogawa discloses a method of coiling a tape-received chip component inside, coiling and cutting the tape on a reel to form a tape leader, wherein the tape leader is the outermost An apparatus for allowing tape to be taped to a peripheral surface of a tape winding is disclosed. Typically, a slot with a constant rectangular cross-section allows the tape to be inserted in any direction and fed through either edge of the lid as long as the mechanical engagement hole of the tape aligns with the advance mechanism of the feeding machine. If there is no required tape orientation within the slot and no specific edge on which the tape must be wound, the component can be misoriented within the slot, the tape can be wound back on the hub, and the transported component can be misplaced on the circuit board. have. The frequency of these errors increases as the speed at which the reel operator must work increases.

If the carrier tape is not positioned on the reel or the feed portion of the tape is not engaged with the advance mechanism so that the part is delivered to the insertion machine in the proper orientation, the customer must return the tape or force them to re-edit or modify themselves. will be. This is a very serious problem and time consuming.

Accordingly, it would be advantageous to mitigate the above disadvantages by having a system and method for replacing reels with traceability, said system and method comprising:

Before the at least one matching female key element of the reel is snugly fitted to the male key element of the shaft, the orientation of the at least one male key element in the shaft of the coiling station is predetermined, thereby By providing a predetermined reel position such that the tape aligns with at least one tape insertion slot on the reel, product defects can be prevented and reduced.
