    • There is disclosed an apparatus for adjusting the origins of module heads of a surface mounting apparatus for a dual gantry, the adjusting apparatus, and method therefor. The invention includes the X-Y gantry consisting of first and second X-axis linear motors and first and second Y-axis linear motors, and having X-Y plane on which first and second reference points and a mark indicating the origin (MIO) are set, first and second module heads installed at the first a nd second X-axis linear motors, first and second vision units installed in vicinity of the first and second module heads, respectively, and for sensing the first and second reference points and the MIO and generating and outputting coordinates of the sensed first and second reference points and the MIO, and a controller for driving the first and second X-axis linear motors and the first and second Y-axis linear motors to move the first and second vision units to the first and second reference points and the MIO, receiving the coordinates output from the first and second vision units to compute offset values relating to the first and second module heads, and, if there are the offset values, setting the origins of the first and second module heads by correcting the offset values. Thus, the repeated precision of the adjustment of the origins can be improved, also, the apparatus for adjusting the origins of the first and second module heads are easily incorporated into the surface mounting apparatus for the dual gantry.
    • 公开了一种用于调整双台架的表面安装装置的模块头的起点的装置,调节装置及其方法。 本发明包括由第一和第二X轴线性电动机和第一和第二Y轴线性电动机组成的XY台架,并且具有第一和第二参考点和指示原点(MIO)的标记的XY平面,第一 以及安装在第一和第二X轴线性电动机上的第二模块头,分别安装在第一和第二模块头附近的第一和第二视觉单元,并且用于感测第一和第二参考点和MIO, 输出感测到的第一和第二参考点和MIO的坐标,以及用于驱动第一和第二X轴线性电动机以及第一和第二Y轴线性电动机的控制器,以将第一和第二视觉单元移动到第一和第二 第二参考点和MIO,接收从第一和第二视觉单元输出的坐标以计算与第一和第二模块头相关的偏移值,并且如果存在偏移值,则s 通过校正偏移值来修改第一和第二模块头的起点。 因此,可以提高原点调整的重复精度,而且用于调节第一和第二模块头的来源的装置也容易地并入用于双机架的表面安装装置中。
