  • Patent number: 6580971
    Abstract: A multipoint inspection system for evaluating manufactured assemblies includes a robotic arm and a robot controller for controlling the robotic arm. A camera is mounted to an end of the robotic arm and includes a camera controller for capturing images. The robot controller is in communication with the camera controller and the robot controller causes the robotic arm to position the camera at a first inspection point. The camera controller then causes the camera to capture a first inspection point image of a manufactured assembly at the first inspection point. The robotic controller then causes the robotic arm to position the camera at a next inspection point where the camera controller then causes the camera to capture a next inspection point image of the manufactured assembly at the next inspection point.

  • Patent number: 6578259
    Abstract: An automated filter changing system comprises a rotatable filter dispensing assembly and a filter clamping assembly. The filter dispensing device receives filter storage magazines in which a plurality of filters are initially stored in the form of connected stacks. The filter dispensing assembly includes a filter separating device having a stationary portion. The filter separating device separates one or more stacks of filters into discrete filter units, such that individual filters are transported sequentially from the filter dispensing device. The filter clamping assembly operates in conjunction with the filter dispensing device to receive one or more individual filter units dispensed therefrom, and provides one or more coupling sites which can fluidly communicate with one or more fluid lines. The filter clamping device couples unused filters to fittings associated with the fluid lines by applying an evenly distributed force to the filters.

    Abstract: There is provided a production line having a plurality of mounting apparatus of electronic components in which the overall production efficiency is sustained by an alternation scheme when a mounting apparatus has a long cycle time due to a high malfunction rate. At a predetermined timing, the rate of unsuccessful pick-up procedure for an electronic component is compared to a predetermined value. If the rate is higher than the value, CPU finds out if the mounting apparatus 2, or 3 is available as an alternate. When the alternate is the apparatus 2, CPU 10 changes the command parameter of the particular mounting procedure, stored in RAM 12, from “M” to “S”, and stops mounting the same component. In the mean time, the mounting apparatus 2 accepts the alternate request from the apparatus 1, changes the command parameter as required, and mounts the same component on a print circuit board.

  • Patent number: 6334248
    Abstract: A technique and machine for transferring discrete areas of material, such as hot stamping foil, from a carrier onto positions spaced apart along a substrate, such as paper. The carrier is dispensed at a rate that is much less than the speed of movement of the substrate. During transfer, a segment of the carrier is moved at the same speed as the substrate while, in between such material transfers, the speed of the carrier is sharply reduced and even reversed in direction in order to maintain the average speed of this carrier segment equal to the reduced speed at which the carrier is being dispensed. This is accomplished by a shuttle mechanism that is moved by its own motor, under control of a microprocessor-based motor control system, in synchronism with the speed of the substrate and transfer operations. This significantly improves the utilization of the material on the carrier, with an improved flexibility to adapt to various substrate speeds and ease of implementation in machinery.

  • Patent number: 5910894
    Abstract: A method and apparatus for assembly particularly addressed to the assembly of automobiles and aircraft done with reconfigurable modular and "intelligent" tooling fixtures (also called jigs, or holding fixtures). Much of the capability of the system is brought by the optical or other non-contact sensing devices incorporated with the tools to provide information on part location, tooling detail location, and automation (such as robots), used to load, weld, rivet, or otherwise perform work with parts in the tool. A preferred version of the invention uses 3-dimensional stereo and/or other simpler electro-optical ranging and feature location sensors operating in real time to perform numerous measurements of location of critical features of assembly tools and the parts placed within them, to even include detection of abnormal features such as missing holes or welds.

  • Patent number: 5864944
    Abstract: An apparatus and method for improving the productivity and accuracy of mounting electronic components on a substrate. The mounting apparatus includes a line-sensor for image recognition, a carriage head 20 having plural nozzles 21a, 21b and 21c aligned along a predetermined axis. The carriage head 20 is transferred along the direction of the aligned nozzles and above the line-sensor 33 of a recognition member 30. The line-sensor 33 takes images in sequence of the electronic components (chip) vacuum chucked by each nozzle 21a, 21b and 21c in order to recognize positions of the chips 12. Then, based on the recognition results, position deviations of the chips 12 with regard to X, Y and .theta. directions are compensated, and the chips 12 are mounted onto specified coordinate spots of substrate 3. The recognition member 30 includes an adjusting means of rotation angle for crossing the longitudinal direction of line-sensor 33 with the transferring direction of nozzles 21a, 21b and 21c at right angles.

  • Patent number: 5806174
    Abstract: In an apparatus for mounting electronic components of the invention, a moving part is attached to a frame of the apparatus and moved freely in front and rear directions by a moving device. Also, first and second movable members are attached to the moving part and freely and independently moved in right and left directions by first and second moving members. First and second fitting heads are attached to the first and second movable members, and independently and freely moved between a supply section and a mounting section in the frame. When the electronic components are held at the first and second fitting heads, the first fitting head moves the electronic components from the supply section to mount onto a substrate in one mounting section, and the second head moves the electronic components from the supply section to mount on a substrate of a different mounting section in the apparatus.

  • Patent number: 5768760
    Abstract: A pipelined system for removing the contents of sealed coin-collection boxes, wherein each box requires a set of different operations to be performed in seriatim to remove the box contents. The operations include removing a seal, opening a box lid, removing the box contents, resetting the lid and resealing the box. The pipelined system comprises a rotary surface for supporting a plurality of the boxes at spaced locations. Stationary surfaces mount a plurality of box-processing units, including pneumatic actuators and processing tools, at spaced stations to form a pipeline. The processing units each perform a different one of the processing operations during each processing cycle. A motor assembly pivots the rotary surface for stepwise positioning the boxes at different ones of the stations. A control system, including computer and pneumatic systems, causes the box-processing units to perform the different processing operations simultaneously on all boxes in the pipeline.

  • Patent number: 5628112
    Abstract: A peer-to-peer control system for a circuit board production line includes multiple processing stations, each of which has an adjustable width conveyor. Control means are provided at each station for controlling the width of the conveyor, receiving board width data signals from an adjacent upstream processing station, and passing the board width data signal, in turn, to an adjacent downstream processing station. A data signal communication network directly connects the controller of each of the processing stations, such as a programmable logic controller, to the controllers of adjacent upstream and downstream stations. Data signals corresponding to the width of circuit boards to be processed by the circuit board production line progress downstream through the line in tandem with circuit boards of that width.
