    摘要： Embodiments include measuring motion characteristics of the workpiece through the placement process. Since the component is placed on the workpiece with some force to ensure proper adhesion to the workpiece, some deflection of the workpiece is expected during the placement cycle. The placement force is adjusted to ensure that the component is safely placed into the solder paste or adhesive. Placement force is adjusted through a number of characteristics including: choice of spring tension in the nozzle; the length of the nozzle and the amount of over-travel into the board; the rigidity of the board and design; and the placement of the board support mechanisms. With proper adjustment of these characteristics and parameters, high quality placements onto the workpiece can be ensured.

    摘要： A digital range sensor comprises a light source, an optical element to focus the light from the source down to a small spot on a target, a second optical element that is mounted obliquely from the source axis, and a prism mounted on a multi-element detector, which in turn is mounted at the focus of the light returning from the target. The purpose of the prism on the detector is to direct the light onto the active surface of the detector at an angle closer to normal incidence than would otherwise be possible. The detector produces digital data which is transferred to a control module for processing and to produce a numerical range measurement.

    摘要： An illumination and imaging system is provided with a co-axial illuminator that does not include a beamsplitter. The co-axial illuminator achieves efficiencies substantially in excess of those achieved with a beamsplitter. In one aspect, an optical stop is used to reflect illumination upon a target. The optical stop includes an aperture allowing light reflected from the target to pass to a detector. The aperture of the stop has an asymmetrical feature that facilitates operation on specular targets.

    摘要： A belt driven reel-to-reel tape cartridge includes two primary tape guides, a guide pin, and two secondary tape guides for guiding the tape to and from respective tape reels. The tape guides and guide pin define a tape guide path between the reels which the extends around the outside of both primary tape guides, both secondary tape guides, and the guide pin.

    摘要： Features of the present invention provide an optical layout that can accommodate the relatively strict enclosure requirements for compact component alignment sensor. Specifically, aspects of the present invention provide a single optical component that reduces the degree of divergence, and preferably substantially collimates light from the plurality of divergent light sources prior to entering the sensing field. In this regard, part count is kept low and the physical size of the optical train itself is relatively small.

    摘要： A pack belt or similar mechanism is provided in a two hub, belt-driven data cartridge to press against the tape pack on the take-up hub side of the cartridge when approximately half of the tape has wound onto that hub. The added load from this pressure reduces the speed of the tape-up hub, which in turn reduces the speed differential between the two hubs. Since the speed differential between the hubs causes a gradient in tape tension (bow-tie) as the tape is moved from BOT to EOT, this reduces or eliminates the bow-tie. Adjustment of the relative tensions between the drive belt and the pack belt allows adjustment of the bow-tie, ranging from the normal bow-tie, to near zero bow-tie, to a negative bow-tie. Coating one side each of the drive belt and the pack belt, then having the coated side of the drive belt contact the uncoated side of the pack belt further reduces bow-tie. Combining the pack belt with self-acting hydrodynamically lubricated guides significantly improves the efficiency of the cartridge/drive system at low tape travel speeds.

    摘要翻译： 在两个轮毂皮带驱动的数据盒中设置包装带或类似的机构，当胶带的大约一半已经卷绕到该轮毂上时，压紧盒的卷取轮毂侧的带包。 来自该压力的附加负载降低了带式集线器的速度，这又降低了两个集线器之间的速度差。 由于当磁带从BOT移动到EOT时，轮毂之间的速度差会导致磁带张力（弓形）的梯度，所以这减少或消除了领结。 调整传动带和包装带之间的相对张力允许调整领带，从正常的领结到接近零的领结，到负的领结。 将驱动带和包装带的每一面涂覆，然后使驱动带的涂覆侧与包装带的未涂覆侧接触进一步减少蝴蝶结。 将包装带与自动加氢动力润滑导向器相结合，可以显着提高墨盒/驱动系统在低磁带行驶速度下的效率。
