20100209227 | Device for Producing an Image by Means of a Sensor, as Well as a Component Placement Unit Comprising Such Device - A device suitable for producing an image of an object disposed in an object space by means of a sensor comprises at least the sensor, a first lens assembly disposed in front of the sensor, a stop plate comprising a light passage disposed in front of the first lens assembly, a second lens assembly disposed in front of the stop plate and the object space disposed in front of the second lens assembly. The device further comprises a light source, as well as a diffuser which is disposed on a side of the object space that is averted from the light source. | 08-19-2010 |
20120328405 | APPARATUS FOR RECEIVING AND POSITIONING VENEERS FED BY CONVEYOR MEANS IN A DESIRED POSITION - The invention relates to an apparatus for receiving and positioning veneers fed by conveyor means. The apparatus comprises means for gripping the veneers and means for detecting the location and/or position of the veneers on a conveyor belt. There is at least one gripping means on both sides of the feeding direction center line of the veneer. The gripping means are arranged to reciprocate essentially in the feeding direction of the veneers and to grip the veneer on its leading edge side and to position the veneer on the basis of the information provided by the detection means to the desired location in the feeding direction of the veneers. | 12-27-2012 |
20130004283 | Control method and apparatus for positioning a stage - Four laser positioning units are used to position and control an X-Y stage which is movable in X and Y directions. For each laser positioning unit, a mirror constantly reflects laser beam to an optical position sensor, where the mirror is integrally mounted on a rotation unit which is integrally mounted on the one side of platform of X-Y stage, where the laser diode is mounted on another rotation unit which is stationary, the optical position sensor is also stationary. Each rotation unit includes a fine rotation stage and a coarse rotation stage, the fine rotation stage has very high resolution but short rotation range, and the coarse rotation stage has a large rotation range but low resolution. When moving the X-Y stage, four fine stages constantly rotate mirror or/and laser to reflect the laser beam onto the optical position sensor, the amount of rotations and geometry of position of laser and mirror gives precisely the position of moving stage. After fine rotation stages nearly reach their rotation limit, the fine stages return to its starting position gradually when the coarse rotation stage moves to keep the laser constantly reflected onto the optical position sensor. The fine stages and coarse stages in different laser positioning units work alternatively to position the stage. In z-positioning unit, a fine rotation stage is used to rotate precisely a spring cantilever so that a stylus tip on an open end of spring cantilever can touch a surface downwardly with preset cantilever deformation which is measured by the capacitance between a capacitive sensor under a piezoelectric stacks and a capacitive film sensor on the top of spring cantilever. | 01-03-2013 |
20130071219 | DOOR DETECTION SYSTEM - A door detection system includes a robot arm unit and a movable unit. The robot arm unit includes at least one bearing platform and at least one level sensing structure disposed on the at least one bearing platform. The level sensing structure includes a plurality of contact sensors, and the wafer carrier device is disposed on the at least one level sensing structure. The movable unit includes at least one movable structure disposed on the robot arm unit. The wafer carrier device has a wafer pick-and-place opening corresponding to the door, and one end of the at least one movable structure can selectively contact the door of the wafer carrier device or been inserted into the wafer carrier device from the wafer pick-and-place opening. | 03-21-2013 |
20130142609 | Device for Producing an Image by Means of a Sensor, as Well as a Component Placement Unit Comprising Such Device - A device suitable for producing an image of an object disposed in an object space by means of a sensor comprises at least the sensor, a first lens assembly disposed in front of the sensor, a stop plate comprising a light passage disposed in front of the first lens assembly, a second lens assembly disposed in front of the stop plate and the object space disposed in front of the second lens assembly. The device further comprises a light source, as well as a diffuser which is disposed on a side of the object space that is averted from the light source. | 06-06-2013 |
20140064902 | Mobile Tip Waste Rack - A method of wasting tips in an automated processing module is disclosed, which includes at least three positions for holding sample racks. One of the positions is a tip waste rack position holding a tip waste rack, which includes tip receiving openings. Furthermore, it includes a SWAP rack holding mechanism for temporarily holding a sample rack. The method includes transferring the tip waste rack from the tip waste rack position to an adjacent sample rack position. Once the tip waste rack is placed in the adjacent sample rack position, the error pipette tip is discarded into one of the tip receiving openings of the tip waste rack. Following this, the tip waste rack is transferred back to the tip waste rack position. The sample rack temporarily placed in the SWAP rack holding mechanism is transferred from the SWAP rack holding mechanism to the adjacent sample rack position. | 03-06-2014 |
