Abstract: A device for curing an obscured photosetting compound in a subassembly part has a base for supporting the assembly and a plate mounted to the base. The plate has a lens that concentrates UV light into a narrow slit in the assembly to quickly cure the compound. In an alternate version, the plate has a parabolic opening with a mirrored surface for gathering the UV light. A third version of the invention uses a rotatable fixture to position the assembly beneath a UV laser light source to cure the compound.

Abstract: An adhesive curing apparatus and method utilizes the end of a tube or optical fiber extending from a UV light source. The tube end is inserted into the mounting hole in the side of a pivot assembly. The tube projects concentrated UV light into the interior of the assembly for curing the adhesive used to bond the bearings to the shaft and the housing. The tip at the end of the tube has beam splitting mirrors or prisms to distribute the UV light more effectively. The interior of the assembly, including the outer surface of the shaft and the inner surface of the housing are smooth, polished metal to further enhance the intensity of the light incident on the adhesive.

Abstract: A hard disk drive actuator pivot cartridge has a sleeve, a coaxial pivot shaft, and a pair of bearings therebetween. The bearings are located near the axial ends of the shaft. The sleeve has a wall thickness that is substantially greater than those of prior art sleeves. The sleeve also has a pair of annular pads that are located axially inward of the bearings. The cartridge mounts inside an actuator comb such that only the pads contact the bore of the comb. The axial location of the pads and the greater wall thickness of the sleeve significantly decrease the bending experienced by the cartridge when it is installed in the comb, and thereby increase the servo stability and performance of the disk drive.

Abstract: Ultraviolet-transparent seals, flange, and sleeve assemblies are used in actuator pivot cartridges for hard disk drives to cure adhesive located inside the pivot housing. The assemblies are formed from silica glass, polymers, or other suitable materials, and focus UV light into hard to reach, high aspect ratio areas between the pivot bearings, sleeve, and shaft. Some of the assemblies use transparent components with convex or fresnel lenses formed into their geometry. With these designs, UV light can enter the pivots axially and/or radially to reach and cure the adhesive regardless of its location.
