    • The invention provides for a placement head for a die placing assembly of an assembler for assembling dice on a carrier. The assembler has an enclosure with a support assembly for operatively supporting a wafer with dies thereon, a die picking assembly for picking dice from said wafer, a die placement assembly for placing the dies onto the carrier, a die conveyance mechanism operatively conveying the dies from the die picking and placement assemblies, and a control system controlling the assembler. The placement head includes a first translation stage mounted on the die placement assembly, said first stage operatively displaceable along a first axis relative to the die placement assembly. The placement head also includes a second translation stage mounted on the first stage, the second stage displaceable perpendicular to the first stage. The placement head further includes a third translation stage mounted on the second stage, the third stage displaceable orthogonally to the first and second stages, as well as a die placer head mounted to the third stage, the placer head shaped and dimensioned to operatively receive a die from the dice conveyance mechanism and to place the dice onto the carrier.
    • 本发明提供一种用于组装骰子的模具放置组件的放置头,用于将骰子装配在载体上。 汇编器具有外壳,其具有用于在其上操作地支撑晶片的支撑组件,用于从所述晶片拾取骰子的模具拾取组件,用于将模具放置在载体上的管芯放置组件,将模具从 模具拾取和放置组件,以及控制组装器的控制系统。 放置头包括安装在管芯放置组件上的第一平移台,所述第一台可相对于管芯放置组件沿第一轴线可操作地移位。 放置头还包括安装在第一平台上的第二平移台,第二平台可垂直于第一平台移动。 放置头还包括安装在第二台上的第三平移台,与第一和第二平台正交可移位的第三台,以及安装到第三阶段的模具沉头,其形状和尺寸设计成可操作地接收 从骰子传送机构死亡并将骰子放置在载体上。
