Abstract

The invention relates to a drilling machine for printed board, which can prevent a drill from getting damaged caused by an ascent/descent of a lifting body. The drilling machine for a printed board includes a movable support, the lifting body provided to be vertically movable via a vertical guide rail of the movable support by driving force of a driving motor including a driving screw lever and a table provided below the lifting body and moving back and forth. A thread in one direction is formed on an upper part of the driving screw lever, a thread in the other direction is formed on a lower part of the lever, and a weight member capable of at least attenuating vibration caused on the thread in one direction by the ascent/descent of the lifting body is screwed together. In addition, a full length of the driving screw lever is located approximately immediately above a spindle mounted on the lifting body.

Description

technical field [0001] The present invention relates to a drilling machine for printed circuit boards. Background technique [0002] The drilling machine for printed circuit boards is constituted, for example, by a combination of the X-axis movement, Y-X-axis movement, and Z-axis movement shown in FIG. Axis motion is partially repeated). [0003] Generally, the movement of the X-axis or the Y-axis means the positioning of the plane, and the movement of the Z-axis means the vertical movement. In addition, -Z movement means the movement (descending) for cutting, and +Z movement means the movement (rising) which pulls the drill which has finished cutting from the printed circuit board. Among these actions, the +Z action can be said to be an action that is actually meaningless. This is because the +Z movement is not used for cutting, but simply returns the drill to its original position. Therefore, in order to provide a device with higher productivity, there is a problem of ...
