    摘要： A device and method for positioning a resin-sealed lead frame that includes semiconductor devices and resin for sealing the semiconductor devices on the lead frame. A break unit is provided for moving the resin-sealed lead frame to a break table. The break unit includes a vacuum suction portion to hold the resin-sealed lead frame during movement and to release it when the resin-sealed lead frame is brought into a receiving opening associated with the break table. The receiving opening is defined by a plurality of guides with the outer tip portions of the guides providing the receiving opening as a space larger than that occupied by the outer configuration of the resin-sealed lead frame. The guides have a slope to position the resin-sealed lead frame onto the break table after it is released in the receiving opening. The break unit further includes push down pins for pushing down and breaking off unwanted extra portions of resin from beneath the resin-sealed lead frame. The break table is further provided with notches which have shapes corresponding to the shapes of unwanted extra portions of resin of the resin-sealed lead frame.

    摘要翻译： 一种用于定位树脂密封引线框架的装置和方法，该引线框架包括半导体器件和用于将引线框上的半导体器件密封的树脂。 提供了用于将树脂密封的引线框架移动到断裂台的断路单元。 断路单元包括真空抽吸部分，以在移动期间保持树脂密封的引线框架并且当树脂密封的引线框架进入与断裂台相关联的接收开口时将其释放。 接收开口由多个引导件限定，引导件的外部末端部将接收开口设置为比树脂密封引线框架的外部构造所占据的空间大的空间。 引导件具有斜面，用于将树脂密封的引线框架在接收开口中释放后将其定位在断裂台上。 断路单元还包括用于从树脂密封引线框架下方推下并分解树脂的不需要的额外部分的推下销。 断裂台还设置有具有与树脂密封引线框架的树脂的不需要的额外部分的形状对应的形状的凹口。

    摘要： A clamping apparatus includes upper and lower platens; one or more tiebars connecting the platens; and an intermediate platen between the upper and lower platens for movement relative to and along the tiebars. Upper and lower mold halves are provided on the upper and intermediate platens, respectively. A linkage connects the lower and intermediate platens. The linkage includes upper and lower links connected with each other for rotation on an intermediate shaft. The upper and lower links are pivotably supported on first and second shafts fixed to the intermediate and lower platens, repectively. The intermediate shaft is operatively connected with a drive mechanism so that the drive mechanism transmits a driving force to the linkage, and the lower platen is moved relative to the intermediate platen. A set of a radical needle bearing and a thrust bearing is used for at least one of the intermediate, first, and second shafts.
