Abstract: A vacuum suction pen which can always be held squarely above a work being done notwithstanding the orientation of a component to be fitted to the work includes a penholder, a pen head, a connecting mechanism, and a suction cup. The suction cup is at an end of the pen head away from the penholder and made of rubber for soft handling. The connecting mechanism is coupled to the penholder and the pen head, and comprises a connecting member, the connecting member comprises a first connecting portion and a second connecting portion, the first connecting portion is disposed in the penholder, the second connecting portion is coupled to the pen head, and the pen head can be rotationally disposed on the penholder. A method for using the vacuum suction pen is also provided.

Abstract: A non-contact measuring device for measuring dimensions of an object using processed light beams from a laser includes a laser source, an attenuator, a lens group, a stage, a charge-coupled device (CCD), and a processor. The stage supports and rotates a measurable object and the light beams passing through or reflected by the object are collected by pixels of the CCD, enabling calculations of the dimensions of the object by the processor.
