Abstract
A printed circuit board conveyor apparatus has a conveyor for moving a planar circuit board components mounted on frames, in a vertical plane, seriatim, along a first path through a spray treatment area. The components are then raised and returned toward a starting point along a second path with additional processing occurring during the return trip. The use of an overhead return along with positive positioning of the components provides substantial efficiency and allows precision and accuracy in treatment of printed circuit board components while minimizing floor space requirements.
Claims8
A printed circuit board conveyor apparatus comprising a spray treatment line for moving a substantially planar circuit board component having first and second sides along a first path from a starting point to a distant point,
- said apparatus comprising a frame means for mounting said circuit board component for movement away from said starting point along said first path to said distant point,
- said frame means extending so as to support each said component in a substantially vertical plane with a component being mounted on each frame means and each frame means comprising a blade means for engaging a guide rail in sliding contact therewith to maintain movement of said frame in a plane,
- liquid spray means positioned on either side of said path for uniformly spraying said circuit board sides with liquid to carry out a printed circuit processing step,
- conveyor guide means for contacting said frame means in supporting relationship therewith to maintain a predetermined position of the frame and fixed position of said circuit board mounted thereon to aid in uniform application of liquids by said liquid spray means, and
- a conveyor drive means mounting said frame means for moving said circuit board in said first path.
In an apparatus for conveying a plurality of printed circuit boards along a first path at a first level, the improvement comprising,
- a frame carrying a printed circuit board,
- said frame defining an outer support perimeter,
- a top hanger section and a lower blade section with said board being substantially arranged in a plane,
- said frame carrying means for supporting a planar printed circuit board component in releasable engagement therewith while being mounted to prevent movement of said board from a predetermined plane while exposed to a plurality of processing conditions.
A frame for use in conveying a plurality of printed circuit boards vertically arranged along a path,
- said frame defining an outer support perimeter,
- a top hanger section and a lower blade section with said board being substantially arranged in a plane,
- said frame carrying means for supporting a planar printed circuit board component in releasable engagement therewith while said board is mounted to prevent movement of the board from a predetermined plane while exposed to a plurality of processing conditions,
- said lower blade section being adapted to move along a straight line path in sliding engagement with a guide rail.
