摘要： A stencil printer for printing viscous material on a substrate includes a frame, a stencil coupled to the frame, and a print head, coupled for the frame, to deposit and print viscous material over the stencil. The stencil printer further includes a substrate support to support a substrate in a print position and a substrate clamping assembly to clamp the substrate in the print position. In a certain embodiment, the substrate clamping assembly includes a pair of rail members coupled to the frame. The rail members are adapted to engage opposite edges of the substrate. The substrate clamping assembly further includes a pair of foils, one for each rail member, with each foil being releasably secured to the rail member in a position so that the foil overlies the substrate. The substrate clamping assembly also includes a pair of clamping members, one for each rail member and foil, to releasably secure the foil in place on the rail member.
摘要翻译：用于在基材上印刷粘性材料的模版印刷机包括框架，联接到框架的模板和联接到框架上的印刷头，以沉积和印刷在模板上的粘性材料。模板印刷机还包括用于支撑处于打印位置的基板的基板支撑件和用于将基板夹持在打印位置的基板夹紧组件。在某个实施例中，基板夹持组件包括耦合到框架的一对导轨构件。轨道构件适于接合基板的相对边缘。衬底夹持组件还包括一对箔，每个箔用于每个轨道构件，每个箔可释放地固定到轨道构件，使得箔覆盖衬底。衬底夹持组件还包括一对夹紧构件，每个夹紧构件一个用于每个轨道构件和箔，以将箔可释放地固定在轨道构件上的适当位置。

摘要： A printed circuit board holding mechanism includes a vertically movable pin support table having at least one tooling pin mounted thereon. A pair of elongated conveyor rails are separated and oriented parallel with respect to each other. The conveyor rails each support a number of pulleys, which pulleys have a drive belt mounted thereon. A segment of each conveyor rail includes a clamping rail that is spring biased downwardly. Clamping rails mounted on opposing rails are oriented to face each other so that foils associated with each clamping rail can engage opposite top edges of a printed circuit board when the movable pin support table is actuated upwardly. The movable pin support table is actuated upwardly so that the tooling pin mounted thereon contacts a bottom surface of the printed circuit board to move the printed circuit board up and off of the drive belts and into engagement with the foils associated with the clamping rails. On or more slotted support strips mounted on the rails are contacted by the pin support table and move with the table to contact the bottom surface of the printed circuit board to provide edge support for the board. In this orientation, the printed circuit board is no longer supported by the resilient drive belts, rather, the printed circuit board is securely held between the clamping rails and the tooling pin.
摘要翻译：印刷电路板保持机构包括可垂直移动的销支撑台，其上安装有至少一个工具销。一对细长输送轨道相互平行地分开并定向。输送轨道各自支撑多个皮带轮，该皮带轮上安装有传动皮带。每个输送轨道的一段包括向下弹簧偏压的夹轨。安装在相对的轨道上的夹持轨道被定向为彼此面对，使得当可移动的销支撑台被向上致动时，与每个夹持轨道相关联的箔可以接合印刷电路板的相对的顶部边缘。向上致动可动销支撑台，使得安装在其上的工具销接触印刷电路板的底表面，从而使印刷电路板向上移动并从驱动带脱离并与与夹紧轨道关联的箔接合。安装在导轨上的一个或多个开槽支撑条与销支撑台接触，并随着工作台移动而与印刷电路板的底表面接触，以为板提供边缘支撑。在此方向上，印刷电路板不再由弹性驱动带支撑，而是印刷电路板牢固地保持在夹持导轨和工具销之间。
