摘要： A method for inspecting composite tape including cover tape bonded to carrier tape comprises capturing a digital image of the composite tape, dividing the seal tracks within the image into a plurality of fragments or segments. The method also provides for analyzing each segment of the seal track for the presence or absence of the seal and for the width of the seal, and assigning a failing grade to the segment if the seal is not continuous within the segment or if the seal has a width less than a minimum width within the segment. The method further provides for notifying a machine operator of a defective seal if the number consecutively-failed segments in the seal track exceeds a defect tolerance. The method also provides for measuring the spacings of the carrier tape edge, cover tape edge, and seal tracks from each other and comparing those spacings to acceptable values.

摘要： A focusable imaging system particularly suitable for use in acquiring digital images for subsequent processing such as in a hand held, omnidirectional symbology or bar code reader by which linear and two dimensional (matrix, maxi-code) bar codes may be imaged over relatively long working distances. The imaging system includes an focusing objective taking lens and a two-dimensional photodetector that operate to form an image of an object such as a bar code in X and Y directions simultaneously and generate an electrical signal representative of the object or code for subsequent downstream processing by which information embedded in the object or bar code may be extracted. Focusing is achieved via a rotating disk that carries a plurality of optical shims or other light controlling surfaces to provide for different focus zones. A through-the-lens (TTL) targeting system is provided to visually assist the user in positioning the reader for a variety of code modalities to assure that a bar code or the like will be captured within the field of view and be sharply imaged on the photodetector when the lens is focused. Two different forms of artificial illumination are provided to accommodate nearby objects or codes that may be either specular or partially diffuse and more distant objects or codes where the reflection characteristics have less impact on image contrast. Elements of the photodetector are used to assess available light levels and activate the artificial illumination system when ambient light levels are low. Ranging through the lens using elements of the photodetector is included to provide information to set the focus of the objective lens in one of many possible focusing zones.

摘要： A scanning system inspects elements, such as ICs, continuously by positioning a second tray containing elements to be inspected adjacent a scan bed in which the elements in a first tray are being scanned. Immediately upon completion of scanning of elements in the first tray, scanning begins on elements in the second tray. During scanning of the second tray, the first tray is off loaded, and a third tray replaces the first tray. The cycle is repealed continuously. Since transport and scanning operations take place simultaneously, transport delay is reduced substantially, as compared to the serial system of the prior art. When the transport, positioning, and off loading operations consume substantially less time than the scanning operation, a fresh tray of elements always awaits scanning upon completion of scanning of elements in a tray. In one embodiment, first and second scan beds are elevated above a conveyor, thereby permitting incoming and outgoing trays to pass on the conveyor below the scan beds without interference with the trays elevated in the scan beds. A replace operation, either on-line or off-line, replaces defective elements detected in the scanned trays with known-good elements, whereby the output of the apparatus is 100 percent known-good elements. An embodiment in which transport and positioning takes longer than the scanning operation, thereby requiring a delay in scanning, is disclosed. This latter embodiment, although it does not provide continuous scanning, nevertheless reduces cycle time by virtue of parallel operation of scanning and transport functions.
摘要翻译：扫描系统通过在第一托盘中的元件被扫描的位置附近放置一个包含待检查元件的第二托盘来连续地检查诸如IC的元件。在完成对第一托盘中的元件的扫描完成后，扫描开始于第二托盘中的元件。在扫描第二个托盘期间，第一个托盘被卸载，第三个托盘取代了第一个托盘。该循环被不断废除。由于传输和扫描操作同时发生，与现有技术的串行系统相比，传输延迟显着降低。当运输，定位和卸载操作比扫描操作消耗的时间大大减少时，在纸盘中的元件的扫描完成时，新的元件盘总是等待扫描。在一个实施例中，第一和第二扫描床在输送机上方升高，从而允许进入和离开的托盘在扫描床下方的传送带上通过，而不会干扰扫描床中升高的托盘。替代操作在线或离线，用已知的元件代替在扫描的托盘中检测到的有缺陷的元件，由此该设备的输出是100％已知的良好元件。公开了一种实施例，其中传输和定位比扫描操作花费更长的时间，从而需要扫描延迟。后一个实施例虽然不提供连续扫描，但是通过扫描和传送功能的并行操作来减少循环时间。

摘要： A three-dimensional optical measurement system, where it is desired to move the light beam or plane to more than one position to increase the amount of data acquired. A rotating disk is provided with segments of lenses, zone plates or other rotationally invariant grating patterns on it. The beam or plane is passed through the segments as the disk rotates and is deflected to predetermined angles. The accurate repeatablility of this arrangement allows the use of calibration data and encoding of the light planes for ambiguity resolution to provide an accurate measurement system. Diverging beam light sources are readily accommodated. Similarly translating frames with segments of translationally invariant lenses or grating patterns may be used. Two-dimensional holographic gratings may be used to generate raster scans.
