PROBLEM TO BE SOLVED: To provide a mechanism for preventing pipe clogging in a chip removal mechanism, more actually, for removing chips easily clogged in a connection part of a dust collection manifold and respective dust collection pipes, for the purpose of the present invention.SOLUTION: For attaining the purpose of the present invention, a printed circuit board processing machine for processing a plurality of printed circuit boards by using a tool 2 such as a plurality of drills has a dust collection pipe 16 connected to respective pressure feet 3 for removing chips generated by the plurality of tools 2 and accumulates the chips in a dust-collector by connecting the dust collection pipe 16 to a dust collection manifold 11, and a mechanism 5 for jetting pressurized gas is preferably provided on the dust collection pipe side of a part for connecting the dust collection pipe 16 and the dust collection manifold 11. Thus, the connection part of the dust collection manifold 16 and the respective dust collection pipes 11, where chips are easily clogged, can be always put in a clean state, so that clogging is not caused. |
