Abstract

This article describes a process and mechanics for automatically loading a cartridge top and spring sub-assembly into a daisy wheel and cartridge bottom sub-assembly. (Image Omitted) Fig. 1 is an exploded view in perspective showing the cartridge bottom and daisy wheel sub-assembly. Figs. 2 and 3 are front and side views, respectively, of the mechanism for performing the loading process. The cartridge top is automatically fed from a vibratory feeder (Image Omitted) bowl (not shown) and positioned in a spring-loaded fixture directly above the leaf spring that is held in position by a gripper. Referring to Figs. 2 and 3, a pick-up head consisting of two electromagnets and a vacuum cup pushes down on the cartridge top until contact is made with the leaf spring. The electromagnets are energized, and the vacuum is turned on.

Load Cartridge Top and Spring Sub-Assembly Onto Daisy Wheel and Cartridge Bottom Sub-Assembly

This article describes a process and mechanics for automatically loading a cartridge top and spring sub-assembly into a daisy wheel and cartridge bottom sub-assembly.

bowl (not shown) and positioned in a spring-loaded fixture directly above the leaf spring that is held in position by a gripper. Referring to Figs. 2 and 3, a pick-up head consisting of two electromagnets and a vacuum cup pushes down on the cartridge top until contact is made with the leaf spring. The electromagnets are energized, and the vacuum is turned on. The gripper jaws open, and the pick-up head raises, holding the cartridge top and spring sub-assembly. The transfer mechanism indexes to position the cartridge top and spring sub-assembly directly over the cartridge bottom and daisy wheel sub-assembly which is clamped

in position on an indexing pallet. The pick-up head lowers and places the top sub-assembly onto the bottom sub-assembly, making one complete daisy wheel cartridge assembly (Fig. 4).
