Abstract

An apparatus for assembly of laminated components to a card base includes a main platen secured to a pair of precision linear bearings to support the card base. Rows of vacuum holes in the platen secure the card by suction effect. A removable track location key at one edge of the main platen includes detent positions engaged by a track location lock, so that the main platen may be locked at any of those positions. A transfer platen extending parallel to the main platen is pivotally secured to the machine base. The transfer platen also includes rows of vacuum holes to hold component strips by suction effect. The transfer platen is rotatable from a loading position to the main platen to deliver a component strip to a precise position on a card secured on the main platen. The method of the invention includes placing a card substrate on the main platen and securing it thereto with vacuum suction. The main platen is positioned to receive a first component strip and secured by the track lock, and the first strip is secured by vacuum to the transfer platen in the loading position. The transfer platen is rotated to impinge the first component strip on the card substrate on the main platen. Pressure sensitive adhesive surface coatings on the components join the assembly. The transfer platen is then rotated to return to the loading position, and the main platen is indexed to a second position to receive another component. This process is reiterated to apply all of the card components on the substrate in accurate placement.

An apparatus for precision lamination of components to a card assembly, including;

a main platen for supporting a card substrate;
means for translating said main platen along a first axis;
track location key means for demarcating preselected positions of said main platen along said first axis;
track lock means for releasably retaining said main platen at any of said preselected positions along said first axis;
transfer platen means for supporting a component to be laminated to the card substrate;
means for rotating said transfer platen means about a second axis to place a component supported thereon onto a card substrate supported on said main platen;
first vacuum suction means for removably securing a card substrate to said main platen, said first vacuum suction means includes a plurality of vacuum holes formed in an upper surface of said main platen and connected to at least one vacuum channel disposed within said main platen;
said vacuum holes arrayed in a plurality of rows, said rows extending generally transversely to said first axis;
a plurality of said vacuum channels connected to said rows of vacuum holes to apply negative gauge pressure selectively to said plurality of rows and apply vacuum suction in selected areas of said upper surface of said main platen;
said means for translating said main platen along a first axis including a pair of linear bearings disposed in parallel, spaced apart arrangement to engage said main platen;
said track location key means including a track location key secured to said main platen and extending generally parallel to said first axis;
said track location key including demarcating indicia to identify a plurality of preselected tracks, each track comprising a narrow band extending across said main platen and the card substrate thereon, said narrow bands extending generally transversely to said first axis;
and,
said track location key including a plurality of detent stops formed in one edge portion thereof, each of said detent stops corresponding to a respective one of said plurality of tracks.
