Title: Cleaning device for plastic lens
Inventor: YAMADA HIROSHI
IPC: B24B13/005
Filed: 1989-12-28
Abstract: PURPOSE:To enable the use of a cleaning device commonly for various types of lenses having different curved surfaces, and the removal of a foreign deposit from the surface without any damage thereto by constituting a cleaning tray with an elastic body and a porous soft material fixed to the tip thereof, and a pad secured to the porous soft material. CONSTITUTION:Upon starting the supply of a cleaning liquid, a shaft 11 is rotated at the predetermined speed with a motor 13, and the linear movement of an operation lever 5 is converted to the oscillation movement of an oscillation arm 3 via a motor 6 for oscillation, thereby oscillating the shaft 11 monolithically with the arm 3. Concurrently, a shaft 41 is rotated at the same speed as the shaft 11, and the surface 27a of a plastic lens 27 is cleaned with the pad 26 of a cleaning tray 23. In this case, even if the radius of curvature of the cleaned surface 27a is larger than the radius of curvature of the pad 26, the whole of time surface 27a can be uniformly cleaned with the pad 26 for the reason that the oscillation radius of the shaft 11 is larger than the radius of curvature of the lens 27, and this lens 27 itself is rotated, while a porous soft material 25 is compressed during a cleaning process. It follows, therefore, that the whole surface of the lens 27 even if special type can be well and properly cleaned, and a foreign material can be removed, regardless of the radius of curvature of the lens 27.
