ABSTRACT:
The present system provides structure to automatically load vertically positioned printed wire boards (hereinafter PWBs), into a processing "line." The present system employs a movable loader device. The movable loader device has multiple levels of PWB rack-cassettes. The rack-cassettes are loaded, into the movable loader device, with PWBs, prior to the movable loader device being engaged with the remainder of the system. Thereafter the movable loader device is rolled on wheels, to be in contact with a locking device, whereat it is secured, so that the PWBs can be precisely aligned with the index-loader-cassette of the processing "line." The PWBs are automatically moved from the index-loader-cassette into and through the transport path. The system further has, in the embodiment described, a masking tape applicator arrangement which can either automatically apply masking tape in uncut form to the PWBs or alternatively can cut patterns from masking tape so that when the masking tape is subsequently applied to the PWBs, certain areas of the PWBs, which are not covered by the masking tape or which are defined by the cut-out patterns, are exposed for future plating. The movable loader device includes a pneumatic lifting system.
