VISION DEVICE CAPABLE OF FOCUS FINE CONTROL

摘要

PURPOSE: A vision device capable of focus fine control is provided to adjust the position of a mirror inside a block and the position of a camera without re-implementing the block. CONSTITUTION: A vision device capable of focus fine control includes a charge coupled device camera(C), a first reflection mirror(A), a laser optical source device(40), and a second reflection mirror(B). The charge coupled device camera(C) senses the laser light incident on a body and outputs an image signal. The first reflection mirror(A) is implemented on a front portion of the charge coupled device camera. The laser optical source device(40) illuminates the laser light for measuring a gap of a welding plate. The second reflection mirror(B) is implemented on the front portion of the laser optical source so as to change the path of the laser light. The angle of the reflection mirror(A) of the charge coupled device camera is selected from a group of materials whose angles are controllable, and the positions of which are also controllable.
