  • Patent number: 5724712
    Abstract: A method and apparatus for automatically welding and handling welded tailored blank composites. The method comprises the steps of transferring first and second sheet component parts from respective input stacks to an assembly table of a welding machine. The sheet components are disposed in a butt joint or an overlapping lap joint configuration and the blanks are welded together along a weld seam thus defining a welded blank. The welded blank is conveyed in a timed step manner from the welding machine to an output stacking machine via a magnetic stepping conveyor and the blank is transferred from the conveyor to an output stack of completed blanks with a stacking machine. An apparatus is provided to carry out the method.

  • Patent number: 5697752
    Abstract: An apparatus for conveying panels, such as vehicle body side panels to and from work stations located at spaced locations along a conveyor includes a panel support frame mounted on the conveyor for movement along the conveying path with the support frame in an elevated generally horizontal conveying position. The support frame carries a plurality of mechanically actuable releasable clamps adapted to retain a panel engaged against a group of locator pads fixedly mounted on one side of the support frame. A second group of locator pads movably mounted on the frame are normally biased into engagement with the panel at spaced locations around its periphery to hold the panel in a predetermined position laterally of the support frame. The support frame mounts an actuator member coupled to all of the clamps to position all clamps in a panel clamping position when the actuator member is in a first position and to position all clamps in a panel release position when the actuator is in a second position.

  • Patent number: 5689876
    Abstract: An apparatus for assembling a photo film unit has a dark box, which has supply openings into which parts are supplied, and an exit opening from which the body loaded with the photo film is exited. Intermediate cells of the dark box shield ambient light and include interlocked outer shutter plates and inner shutter plates which are disposed in the supply openings and the exit opening. A cassette supplying loader and a robot hand transfer the cassette into the dark box, while a leading tongue of the photo film is protruded from the cassette shell, with a remaining portion of the photo film contained as a roll. A roll forming fork device winds the photo film to a predetermined length from the cassette and forms the photo film into the roll. A photo film mounting mechanism swings the roll and the cassette shell together to change orientation thereof, and loads the roll and the cassette shell into the body.

  • Patent number: 5513427
    Abstract: A system for producing parts/substrate assemblies each of which includes a substrate such as a ceramic substrate and a plurality of parts such as LSIs mounted on the substrate. After the LSIs for one lot of the production have been checked for excess or deficiency, etc. by a collating device, they are formed with solder bumps and then inspected. The LSIs are automatically arranged on empty work pallets as parts kits by a kit setting apparatus, and the work pallets on each of which the corresponding LSIs have been arranged as the parts kit are moved into a stocker. A host computer gives a command for mounting the LSIs on the ceramic substrate on which they can be mounted, on the basis of information indicating the stocked pallet and information indicating the progress of the ceramic substrate. An LSI mounting apparatus reads the serial No. of the introduced ceramic substrate, and requests the stocker to deliver the work pallet on which the associated LSIs have been arranged as the parts kit.
