Embodiment Construction

[0011] In the accompanying drawings, an apparatus for high-speed drilling of printed circuit boards or the like according to the invention is generally indicated by reference numeral 1 . The device comprises first and second drilling units 2a,b mounted on the same support 3 and arranged symmetrically opposite each other. Both drilling units are actuated by the same actuator member 4 which is arranged centrally between the two drilling units on the support 3 . The actuator member 4 comprises a linear actuator 6 with double-sided protruding rods, each rod segment 5a, b acting in the manner described below, and two independently actuated ball screws 6a,b on the corresponding unit 2a,b.

[0012] The two drilling units 2a, b are identical, therefore only one of them will be described in detail, and unless otherwise specified, the same description and reference numerals apply to both drilling units.

[0013] Each unit 2a,b comprises a corresponding drill bit 8a,b. Each drill bit ...

Abstract

A device for drilling printed circuit boards comprises a first drill head (8a) guided along a drilling axis (Z) towards and away from a corresponding first drilling plane ((XY)a) substantially perpendicular to the drilling axis, the drilling plane ((XY)a) being displaceable with respect to the drilling axis (Z) during a positioning movement of the board to be drilled (Pa), the head (8a) being displaceable along the axis (Z) towards the plane ((XY)a) during a cutting movement and during an opposite return movement from this plane ((XY)a); the device comprises a second drill head (8b) rigid with the first head (8a) during the movement along the axis (Z) and a second drilling plane ((XY)b) parallel to the first plane and facing the second drill head (8b) in an arrangement such that a return movement of the first head (8a) corresponds to a cutting movement of the second head (8b) and vice versa.

Description

technical field [0001] The invention relates to a drilling device for printed circuit boards. Background technique [0002] In the manufacture of printed circuit boards, a large number of holes must be provided for each board in at least some areas where circuit components are soldered. These holes are obtained by a drill adapted to drive a special drill tip at high speed. When the positioning movement of the plate to be drilled is manipulated in a drilling plane perpendicular to the drilling axis (axis Z), the drill head is generally displaced along this drilling axis. [0003] Each drill bit thus performs a cutting movement towards the drilling plane and through the thickness of the board to be drilled, and a return movement during which the drill head moves away from the drilling plane so that the board to be drilled can be repositioned . [0004] Logically, the return movement itself is unproductive, and even if the return movement could be performed at a relatively h...
