Module Transport System

System 10 transports circuit modules M past the various work stations A-H of a solder machine 20 which includes a total immersion solder station C and a wave solder station E and allows modules M to be processed on an in-line and/or continuous basis.

The modules M are guided and supported by plural, e.g., five, channel- shaped parallel guide tracks T, as shown in the cross-sectional view of Fig. 2, with the module pins P being positioned downwardly between the open spacing between adjacent pairs of supporting tracks T. A pusher finger F is placed in contact with the trailing edge of a module M. When actuated, finger F moves the particular contacted module M and a number of others stacked in front of it along the track T.

The contour of track T is curved at appropriate stations, e.g., the flux station B, where the pins P of modules M are placed in contact with, i.e., dipped into, the particular processing material, e.g., flux, contained in the particular work station tank as the module is advanced by fingers F. The fingers F are pivotally attached to a cam roller 12, which in turn is located in a channel cam track 14 which has a contour compatible to the contour of guide tracks T. Roller 12 is rotatably mounted to an arm 15 which is pivotally connected to a link of drive chain 16. The speed of the chain 16 and the contours of the tracks T, 14 at the various stations determine the time that the modules M are processed through each station. F...
