| 161 | Automated flash removing apparatus | US884761 | 1997-06-30 | US6086295A | 2000-07-11 | Norm Novak; Eric Bailey |
| This invention is of an automated flash removal apparatus which features counter-rotating trimming wheels which are positioned against the molded flexible urethane part or the molded flexible polyvinyl chloride part. The force of the trimming wheels against the part undergoing the flash removal process is adjustable and is controlled by opposing tension springs. The trimming wheels may by set at any angle to the part so as to enhance the flash removal characteristics. The trimming wheels are guided along the sides of the part by interchangeable guide bars which may be profiled to accommodate parts which present surfaces that are not substantially straight. The trimming wheels utilize a textured pattern which operate to abrade the flash from the part, thereafter polishing the part on the return pass. | ||||||

| An apparatus for loading, chamfering and unloading a ceramic or ceramic/polymer substrate for electronic components. An automatic part loader moves substrates in a row as a unit, using a frangible pin to push the parts. The part loader separates the first of the substrates from the rest, and a load pedestal pushes the first substrate up into a loading/unloading nest. The load pedestal is mounted on rods so that the substrate may move laterally to center itself in the nest. The nest then rotates to load the substrate onto a movable process pedestal. The chamfering apparatus includes a pair of spaced, rotatable cutting spindles for chamfering edges and corners on the substrate. The cutting spindles include: i) separate top and bottom edge cutters for simultaneously chamfering top and bottom of edges of a substrate secured on the carrier as the substrate passes between the spindles and ii) corner cutters for simultaneously chamfering corners of a substrate secured on the carrier as the substrate contacts the spindles. The pedestal rotates the substrate about an axis normal to the plane of the substrate and moves the substrate in a direction normal to the plane of the substrate to present unchamfered edges and corners to the cutting spindles. A disc brake on the process pedestal may be actuated to prevent rotation of the substrate during chamfering. An enclosure surrounds the substrate, chamfering cutters and process pedestal during chamfering and utilizes the air flow supplied by the rotating cutters to propel chips into a particle collector. | ||||||
| 163 | Automatic printed circuit board two-bevel forming machine | US39697 | 1998-03-16 | US5971680A | 1999-10-26 | Hsien-Li Kuo |
| Disclosed is an automatic printed circuit board two-bevel forming machine which includes a conveyer, a first cutter assembly which is disposed above the conveyer, and a second cutter assembly which is disposed below the conveyer. The first cutter assembly includes a first rough and a first fine bevel cutter. The second cutter assembly includes a second rough and second fine bevel cutter. The rough and fine bevel cutters of the first and second cutter assemblies incline at a suitable angle toward the upper and lower edges of the PCBs being conveyed. The rough and fine cutters stretch or shrink to a suitable position controlled by a pneumatic driving device. When the PCBs pass through the first and second cutter assemblies sequentially by means of the conveyer, the rough and fine bevel cutters of the first cutter assembly cut and grind the upper edge to form an upper fine bevel, and the rough and fine bevel cutters of the second cutter assembly cut and grind the lower edge to form a lower fine bevel. A very fine two-bevel edge is obtained without any manual operations, and the manufacture cost is thus reduced. | ||||||
