Patent number: 7428326Abstract: The present invention features a method whereby each vacuum nozzle in a multi-spindle component placement machine is inspected placement cycle. This process also allows for updating calibration of the nozzle position as well as immediate feedback regarding the condition of the vacuum nozzle. A chipped orifice or otherwise damaged nozzle is detected using a vision system and comparing the currently acquired image of each nozzle with the image of an “ideal” nozzle. Likewise, contamination such as adhesive on the nozzle is detected before that contamination can affect placement accuracy. Because of the nozzle inspection during the placement cycle, there is no slowdown of the placement machine cycle rate.Type: GrantFiled: December 2, 2002Date of Patent: September 23, 2008Assignee: Universal Instruments CorporationInventor: Koenraad Gieskes

The encoder system comprises, a read head, a shoe structure adjacent the read head, and an encoder tape. The encoder tape is adapted to be read by the read head. The shoe structure is adapted to locally support the encoder tape and locally dampen a vibration of the encoder tape as the encoder tape is read by the read head.Type: GrantFiled: May 6, 2004Date of Patent: October 16, 2007Assignee: Universal Instruments CorporationInventors: Michael D.

Patent number: 7146717Abstract: The present invention features a method and apparatus wherein a component in a component placement machine is rejected during the placement cycle and subsequently retained in a component rejection station. A component is imaged and the image processed using an automated vision system. The image processing determines whether the component is placeable based upon a comparison of the component image to preprogrammed mechanical parameters for the component. A non-placeable component is rejected into a reject station with means to retain the component. Because a component can not escape the reject station, there is no degradation of the placement machine performance.Type: GrantFiled: April 20, 2004Date of Patent: December 12, 2006Assignee: Universal Instruments CorporationInventor: Jack A. Kinback

Patent number: 7040137Abstract: The present invention features a method whereby the vacuum nozzle of each extendable vacuum spindle in a multi-head component placement machine may be calibrated during component pick/place cycles. Calibration of each vacuum nozzle ensures accurate location of the vacuum nozzle over a component at a component pick station. This is particularly important with extremely small components where a slight misalignment of a vacuum nozzle with a component to be picked could result in a missed pick. Because of the vacuum nozzle inspection and calibration on the fly during the placement cycle, there is no slowdown of the placement machine cycle rate.Type: GrantFiled: July 28, 2003Date of Patent: May 9, 2006Assignee: Universal Instruments CorporationInventor: Koenraad Gieskes

Patent number: 6267020Abstract: A drive mechanism for a variable center distance component insertion machine having a pair of component insertion tooling assemblies mounted adjacent each other so as to be laterally adjustable inwardly and outwardly relative to each other. Each tooling assembly has a gear rack mounted at its top. The racks engage an elongated pinion gear mounted proximate the toolings so as to engage the pair of tooling assembly gear racks. A servo motor rotates the pinion and, thereby, reciprocates the tooling assemblies toward and away from a circuit board. The tooling assemblies are adjusted laterally by a second servo motor coupled to the tooling assemblies by a double screw lead. During the lateral adjustment of the tooling assemblies the pair of rack gears remain in constant mesh with the elongated pinion gear.Type: GrantFiled: July 30, 1998Date of Patent: July 31, 2001Assignee: Universal Instruments CorporationInventors: Robert Macchiarella, Peter J.

Patent number: 6160620Abstract: An optical sensor for use on an electronic component placement machine. A spindle tip on a placement head for the machine holds the electronic component to be placed on a printed circuit board by means of, for example, a vacuum. A spindle driver housing is mounted surrounding the spindle-spindle tip combination such that the spindle tip can move relative to the spindle driver housing vertically, due to bias mounting. A light beam from an optical emitter passes through an opening in the spindle driver housing to a first mirror mounted at 45.degree. on a first inside surface of the spindle driver housing. The light is reflected from the first mirror to a second mirror on a second inside surface of the spindle driver housing. The second mirror is also at 45.degree.. The light beam is then reflected from the second mirror through a second opening on the other side of the spindle driver housing to an optical receiver.Type: GrantFiled: August 27, 1999Date of Patent: December 12, 2000Assignee: Universal Instruments CorporationInventor: John E.

Patent number: 6078114Abstract: A variable reluctance linear motor has a stator and an armature mounted so as to be movable along the length of the stator. Armature bearings are mounted to the armature via mechanical vibration dampers and contact the stator so that vibrations in the stator are transmitted to the bearings and dissipated in said vibration dampers. A sensor is mounted to the armature for obtaining position data for the armature with respect to the stator. A controller then calculates the phase currents for the motor phases based on the position data and a desired force value. The phase currents are calculated to maintain a minimum normal force between the armature and said stator, thereby further reducing vibrations. A conditional filter is applied when armature is within a predetermined distance from a desired location. The conditional filter, after a time delay, clamps the velocity feedback to a predetermined range and simultaneously reduces the velocity loop gain.Type: GrantFiled: April 8, 1998Date of Patent: June 20, 2000Assignee: Universal Instruments CorporationInventors: Steven C. Bessette, Charles A. Coots, James E. York, Andrew Zalesski
