Definitions

• the present disclosure relates generally to tape and reel machines configured for loading and/or unloading reels that carry a flexible tape having sealed pockets or wells in which components such as semiconductor devices reside. More particularly, aspects of the present disclosure are directed to a tape reel turret apparatus configured for carrying a plurality of tape reels, and selectively rotating a given tape reel to a feeding position such that the tape reel can be loaded or unloaded by a tape and reel machine, while one or more other tape reels carried by the tape reel turret apparatus can be attached to or detached from from the tape reel turret apparatus.
• Tape and reel machines transfer components such as semiconductor devices (e.g., semiconductor die or packaged integrated circuit chips) onto a flexible linear tape, and concurrently feed the flexible linear tape to a tape reel while the reel is spun. As a result, the flexible linear tape is progressively circumferentially wound around the tape reel. This provides an efficient manner of storing the flexible linear tape and the components carried thereby. Once a tape reel that is receiving the flexible linear tape is fully loaded with a given length of the flexible linear tape, this full reel must be replaced with an empty reel such that additional components can continue to be transferred to the flexible linear tape, and the flexible linear tape can continue to be fed to, wound around, and stored on a tape reel. That is, the full reel must be changed or swapped out for an empty reel.

• first, second, and third tape reels l lOa-c are each initially empty, a first arm 128a carrying the first tape reel 110a can be transitioned to the feeding position, after which the first tape reel 110a can be immediately receive and be loaded with the flexible linear tape 12.
• the first arm 128a can be automatically rotated away from the feeding position simultaneous with rotation of a second arm 128b canying the second tape reel 110b toward and to the feeding position.
• the second tape reel 1 10b can immediately be filled or loaded with the flexible linear tape 12, thereby eliminating any tape and reel machine interruption or downtime associated with changing or swapping out the full first tape reel 110a for an empty reel 110a.
• the second arm 128b can be automatically rotated away from the feeding position simultaneous with rotation of a third arm 128c carrying the third tape reel 110c toward and to the feeding position.
• the third tape reel 110c can immediately be filled or loaded with the flexible linear tape 12, once again eliminating any interruption or downtime associated with reel changing.
• the fully loaded first and second tape reels 1 10a,b can be (a) removed from the multi-arm module 120, and (b) replaced with empty tape reels 1 10a,b while the third tape reel 1 10c is being filled or loaded, thereby maximizing the throughput of the tape and reel machine 10.
• Analogous considerations apply when the flexible linear tape 12 is unloaded from multiple tape reels l lOa-c.
• aspects of particular embodiments of the present disclosure address at least one aspect, problem, limitation, and/or disadvantage associated with exiting manners of loading and unloading tape reels in association with tape and reel machine operation. While features, aspects, and/or advantages associated with certain embodiments have been described in the disclosure, other embodiments may also exhibit such features, aspects, and/or advantages, and not all embodiments need necessarily exhibit such features, aspects, and/or advantages to fall within the scope of the disclosure. It will be appreciated by a person of ordinary skill in the art that several of the above-disclosed systems, components, processes, or alternatives thereof, may be desirably combined into other different systems, components, processes, and/or applications. In addition, various modifications, alterations, and/or improvements may be made to various embodiments that are disclosed by a person of ordinary skill in the art within the scope and spirit of the present disclosure.
