An automated optical inspection (AOI) tool may be configured to receive tape from a loaded reel (e.g., a source reel, or a tape and reel device, among other examples). The loaded reel may deliver components (e.g., integrated circuits (ICs)) for inspection via the AOI tool. The loaded reel may be configured with tape loaded onto (e.g., wound around) the loaded reel, such that when the tape is unloaded (e.g., unwound), the tape delivers components along a linear path for inspection via the AOI tool. After inspection via the AOI tool, an inspected portion of the tape may be stored by winding the inspected portion of the tape around another reel farther along the linear path.
Aspects of the present disclosure are best understood from the following detailed description when read with the accompanying figures. It is noted that, in accordance with the standard practice in the industry, various features are not drawn to scale. In fact, the dimensions of the various features may be arbitrarily increased or reduced for clarity of discussion.
The following disclosure provides many different embodiments, or examples, for implementing different features of the provided subject matter. Specific examples of components and arrangements are described below to simplify the present disclosure. These are, of course, merely examples and are not intended to be limiting. For example, the formation of a first feature over or on a second feature in the description that follows may include embodiments in which the first and second features are formed in direct contact, and may also include embodiments in which additional features may be formed between the first and second features, such that the first and second features may not be in direct contact. In addition, the present disclosure may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.
Further, spatially relative terms, such as “inner,” “outer,” “inward,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. The spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. The apparatus may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein may likewise be interpreted accordingly.
To operate a system that includes a loaded reel, an AOI tool, and an empty reel to receive tape when unloaded from the loaded reel, an operator may manually install the loaded reel at an in-port side of the AOI tool and may install the empty reel at an out-port side of the AOI tool. The operator may manually pull tape out of the loaded reel and through the AOI tool. The operator may feed the tape into the empty reel and attach the tape to the empty reel. The operator may then operate the AOI tool to inspect IC chips and/or dies on the tape until the tape is unloaded from the loaded reel and wound around the empty reel. After operating the AOI tool, the operator may manually unwind the tape from the empty reel (now loaded with the tape) until the tape is wrapped around the loaded reel again. However, manual installation and/or operation may cause the tape to be uncentered on the empty reel, cause jamming, increase operation delays, and/or the like.
Some implementations described herein provide techniques and apparatuses of an inspection system that uses a reeling device to automatically receive material (e.g., tape) that is unwound from a loaded reel. The reeling device may include a reel coupled to a motor (e.g., a motor that includes the reel, a motor and a reel that is removable, and/or the like), one or more guiding blocks, one or more tracks (e.g., slides) through which the one or more guiding blocks may travel generally towards or away from the reel, a force application device (e.g., a spring) to cause the one or more guiding blocks to travel though the one or more tracks or to resist travel through the one or more tracks, and/or the like.
In some implementations, the one or more guiding blocks may be configured with an opening at a receiving end and may have inner surfaces (e.g., proximate to the reel) configured to guide a received material (e.g., tape) on a path around a surface of the reel. In some implementations, the inner surfaces of the one or more guiding blocks may be arc-shaped to generally follow the surface of the reel.
The inner surfaces of the one or more guiding blocks may be spaced with different distances from a surface of the reel (e.g., when the reel is unloaded). In some implementations, the one or more guiding blocks may be arranged such that a first guiding block, that is first along a path around the surface of the reel, has an inner surface at a first distance from the reel. A second guiding block that is second along the path around the surface of the reel may have an inner surface at a second distance, with the second distance being less than the first distance. In some implementations, one or more guiding blocks along the path around the surface of the reel have inner surfaces that are progressively closer to the reel. In this way, respective inner surfaces of the one or more guiding blocks may collectively form a generally spiral-shaped path around the reel.
Based on using the reeling device as described herein, the reel may receive the material from a source reel without an operator manually feeding the material into the reel and/or attaching the material to the reel before operating the AOI tool. Additionally, or alternatively, the reeling device may improve centering of the material on the reel, reduce jamming, reduce operation delays, and/or the like, any or all of which improve operation of the inspection system.
The tape and reel feeder device 102 may be configured to store, wind, and/or unwind material (e.g., tape with IC devices and/or dies) from one or more loaded reels. In some implementations, the tape and reel feeder device 102 may be configured to automatically feed material from one or more loaded reels stored thereon. For example, the tape and reel feeder device 102 may be configured to unload a first tape from a first loaded reel, receive (e.g., reload) the first tape back onto the first loaded reel (e.g., after optical inspection), then repeat the process with a second tape loaded on a second loaded reel. In some implementations, the tape and reel feeder device 102 may be loaded with a plurality of loaded reels and may be configured to automatically unload and load tapes thereon in series. The tape and reel feeder device 102 will be described in further detail in connection with
The AOI tool 104 may be a tool that uses a camera or other optical device to inspect components. For example, the AOI tool 104 may be configured to inspect IC devices and/or dies on material as the material is delivered through an inspection area. The AOI tool 104 may inspect for defects in the IC devices and/or dies, such as misplacement of sub-components, soldering defects, and/or the like.
The reeling device 106 may be configured to receive material (e.g., tape) from the tape and reel feeder device 102 onto a rotation component or onto a reel coupled to the rotation component. For example, the reeling device 106 may be configured to receive material from the tape and reel feeder device 102 after inspection by the AOI tool 104.
In some implementations, the reeling device 106 may be configured to receive the material, load the material onto a reel, and then unload the material back to a source reel (e.g., a previously loaded reel). In some implementations, the reeling device 106 may be configured to receive the material to load onto a removable reel (e.g., for tape and reel packing). The reeling device 106 may be configured to receive a first material (e.g., a first tape) from a first loaded reel from the tape and reel feeder, load the first material onto a reel, unload the first material from the reel onto the first loaded reel, receive a second material from a second loaded reel from the tape and reel feeder device, load the second material onto the reel, unload the second material from the reel onto the second loaded reel, and so on. In some implementations, the reeling device 106 may be configured to automatically receive and unload material associated with multiple loaded reels in series. The reeling device 106 will be described in further detail in connection with Figs.
The controller 108 may include one or more interfaces for providing power and/or control signals to the tape and reel feeder device 102, the AOI tool 104, and/or the reeling device 106, among other devices. In some implementations, the controller 108 may be configured to receive input from an operator, the tape and reel feeder device 102, the AOI tool 104, and/or the reeling device 106, among other examples. For example, the controller 108 may receive an input (e.g., from an operator, and/or the tape and reel feeder device 102, among other examples) that indicates that a loaded reel of the tape and reel feeder device 102 is ready to be unloaded and may provide power and/or a control signal to the reeling device 106 to operate a motor in a loading operation mode.

In some implementations, each of the guiding blocks 204 along the path around the surface of the rotation component and/or reel 202 (e.g., oriented with the opening 208 as the beginning of the path) may be progressively closer to the surface of the rotation component and/or reel 202. In this way, the guiding blocks 204, and the inner surfaces 206 of the guiding blocks 204, may form (e.g., collectively) a generally spiral-shaped path around the rotation component and/or reel 202.
