Pallet for Automated Assembly Line
A very flat, lightweight, strong and rigid pallet for automated assembly line
usage is made by sandwiching an aluminum honeycomb core and an aluminum
tubular frame between two thin aluminum skins.
The Figure shows that a rectangular Pallet Frame is made of extruded
aluminum tubing 1, with rectangular cross-section, welded at the corners 2. The
space enclosed by Frame 1 is filled with aluminum Honeycomb 3 and thin
aluminum Skin 4 is cemented on top and bottom by a thin layer of epoxy. Holes
are drilled to mount Handles 5. Holes are drilled at two diagonally opposite
corners to mount Locator bushings 6. Bushings 6 are conically recessed on the
bottom to permit accurate location of the pallet on the assembly line. A number of
holes 7 are drilled along two edges and across the middle to permit mounting of
parts fixtures such as 8. A replaceable Wear Pad 9 of conductive plastic is added
on the bottom to complete the Pallet assembly.
