Abstract:
1. A method for attaching a synthetic filter material to a filter tower frame in an ink jet printer cartridge, comprising: providing laser beam source and a filter clamping fixture for laser beam transmission welding of the filter material to the filter tower frame, the clamping fixture including a base, slide rods attached on first ends thereof to the base, an optics support plate attached to second ends of the slide rods, a movable platform for holding an ink cartridge slidably disposed on the slide rods between the base and the optics support plate, a platform moving device for translating the platform to and from a laser welding position, and a laser beam transparent plate suspended by support legs from the optics support plate to a position between the movable platform and the optics support plate, placing an ink cartridge onto the movable platform, the ink cartridge having the filter tower frame therein; positioning the synthetic filter material onto the filter tower frame in the ink cartridge; moving the movable platform toward the laser beam transparent plate so that the synthetic filter material is disposed between the transparent plate and the filter tower frame and is in intimate contact with a perimeter of the filter tower frame; and laser welding the synthetic filter material to the filter tower frame by heating the perimeter of the filter tower frame with a laser beam from the laser beam source having sufficient power to melt a portion of the filter tower frame for melt flow of the portion of the frame through pores in the synthetic filter material.
