  • Method of manufacture of lens and retainer assembly for instrument cluster
    Patent number: 5645666
    Abstract: To manufacture a lens-retainer subassembly for an instrument cluster, a lens is cut from a flat acrylic sheet by a laser operation, and the resulting flat lens is pressed against the curved surface of a retainer by ultrasonic welding apparatus and bonded to the perimeter of the retainer. The retainer surface and a welding horn are shaped to conform to the desired lens shape and to portions of the retainer so that as the horns are moved together the lens will be squeezed between two complementary curved surfaces into the desired shape, and the welding fixes the lens shape.
