Abstract

A cleaning apparatus for circuit boards, a first conveyor (3 in fig 3, is hidden behind 2 in fig 1) delivering the boards to one of at least two cleaning shells 200 held on a motor driven axel mounted to support 50 such that the shells rotate to deliver a cleaned board to second conveyor 1 having weep holes. The shells thus utilise gravity to allow both sides of the board to be brushed by the mechanism in the shells. Between the loading and unloading position of the axel, there is a brush cleaning position. A mechanism inside the shell (figures 5 to 9) moves with the aid of a gear (701 fig 5) mating with fixed internal gear (601 fig 8) to both turn tubes carrying brushes for cleaning the board surface and to move a stop rod down into the shell to lower the board into the shell and past the brushes. The stop rod is fixed to a chain (207 fig 5) running between spaced turntables (205, 206 fig 5) connected to the gear 701. The brushes can be cleaned by cleaning water from discharge tube 53 when the shells are temporarily aligned (not shown) with a second motor driven shaft (100 fig 8) fixed to the support. The shaft drives threaded rods( figs 7, 9) that are located inside the brush tubes and mate with threads inside the tubes to preferably drive the brushes to rotate out of the cleaning space in the shell to a temporary cleaning position. The present invention is able to automatically clean two sides of the circuit board as well as brushes, thereby avoiding a failed cleaning of the circuit board due to dirty brushes.
