    摘要: An improved lightweight z-axis (vertical) drilling apparatus for a commercial PCB drilling systems that uses a pair of unitary z-axis movement guides that integrate the vertical, guided movement of the linear actuator, spindle and pressure foot of a PCB drilling apparatus. The linear actuator is positioned directly above and coupled to the spindle, and the unitary z-axis movement guides situated such that the such that the center of mass of all of the drilling assembly's moving components is collinear with the axis of rotation of the motor and spindle. The combination of these improvements allows for faster drilling times, shorter drilling cycles, less drill bit wander, slower drill bit dulling and less drill bit breakage.

    摘要: A system and method for optimizing drill coordinates in a multi-layer printed circuit board, to correct for interlayer shift during lamination. A set of test patterns, in the form of a cross formed by two orthogonal conductor lines, are defined at each corner of each layer in the same nominal location. Under ideal conditions, the test patterns of the layers in each corner are lined up one above the other, without any offset. A counter sinking tool is used to cut a conical bore in the location of the test patterns, so that every test pattern cross is interrupted in four places, generating a four segment pattern in each layer. A high resolution camera is placed above the countersunk bore to form a single image of the exposed segment edges of all the test patterns exposed by the bore. The image is analyzed to determine the amount of shift of each layer. If all patterns are perfectly concentric, all crosses are perfectly aligned. By measuring the shift of each pattern from the nominal position, the amount of shift in each layer is determined. The process is repeated for the test patterns at each corner of the board, and the resultant layer shift data is processed to optimize the drilling pattern for the board.

    摘要: A pinless router comprising a router coupled to a movable support arranged and configured such that it has at least one separable portion which may be decoupled from the remainder of the support, a means for vertically moving the router and the support, a helical brush having a large central opening concentric with the router tool and which engages with a work piece when the pinless router is in operation, a means for moving the router together with the support in a horizontal plane, a means for decoupling the separable portion from the remainder of the support and a continuous vacuum applied to the central opening in the brush.In operation, the pinless router is moved downwardly until the brush engages with the surface of the work piece. The routing operation is then substantially performed until just before the routing is completed. The pinless router is then stopped and moved downwardly until the separable portion engages with the work piece. The separable portion is then decoupled from the remainder of the support and the routing operation is completed. The separable portion is then recoupled to the support and the pinless router is moved upwardly and returned to the starting point.

    摘要: A collet formed as a unitary metal or steel cylinder machined so as to allow three identical weights, joined by three identical flexures to reside, equally spaced about the axis of rotation of the collet. The weight's outer surface is defined by a single length radius having a pair of centers including the collet's axis of rotation. As the spindle revolves, kinetic energy built up in the weights forces the leading edge of the weights outward from the axis of rotation until some portion of the outer face of the weights frictionally engage the inner surface of the spindle shaft. The trailing edge of the mass of the weights deflects inward thus gripping the machine bit tighter.

    摘要: A high speed drilling system is disclosed for high speed drilling of very small holes in workpieces such as printed circuit boards. The X-Y positioning system includes air bearings to provide lift between the stationary guide beams, the crossbeam and the top table, and further includes a vacuum preloading apparatus for providing a preloading force between the table and the guide beam. The preload force dampens Z axis oscillations which can result in drill bit breakage. The top table is a lightweight honeycomb structure, whose effective rigidity is virtually that of the guide beam due to the vacuum preloading. The system includes pairs of spindles, one a conventional spindle for drilling holes larger than about 0.125 inches, and the other a high speed spindle for drilling holes in the range of about 0.003 to 0.125 inches. The high speed spindle includes a stationary spindle body carrying the stator of the rotary drive motor. Only the spindle rotor is translated along the Z axis to perform the drilling movements. The rotor is supported within the spindle body by rotary and linear air bearings, and is axially driven by a linear motor. A toolchanger loaded by clips carrying the drilling bits is mounted on the top work table, and minimizes the time required to change drilling tools. The clips minimize the manual handling of the fragile drill bits. A vacuum hold-down appratus is employed to secure the workpieces to a drilling station.

    摘要: A positioning system for a gantry adapted to move in the horizontal, X-Y plane that utilizes up to 80% less energy to operate than commercial machines, while at the same time decreasing the position settling times by 50%, and achieving this with an “in position window” of 2-3 microns, (a settling window) beating the current industry in position window of 7-12 microns. It accomplishes this through a novel synergistic overall design that utilizes a much lighter and much stiffer moving mass resulting in the moving components having an increased natural frequency. With this system on any style of PCB drilling machine, the drill bit life is extended in two ways: they do not dull as fast and they do not break as often. This is because the small in position window ensures that as the drill bits plunge into the substrate to be drilled (a PCB board) the drill unit sees very little motion in the horizontal plane thus keeping the bits from wandering upon hole initiation and from experiencing excessive horizontal plane sheer forces (side loads) when starting their plunge into the substrate.
