Title:
METHOD AND DEVICE FOR ADJUSTING MUTUAL POSITION OF COMPONENTS ADJACENT TO EACH OTHER
Document Type and Number:
Japanese Patent JP3251542
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a technique for measuring and setting relative component orientation and isolation distance by projecting a coherent light beam on one end of a gap formed between opposite surfaces of adjacent components.
SOLUTION: The coherent light beam 25 is projected on one end of the gap 60 formed between the opposite surfaces 52, 57 of the adjacent components 50, 55. This light beam is projected so that corresponding light pattern is projected from the other end of the gap 60. Thus, the constitution of the light in the obtained pattern shows the relative orientation of respective opposite surfaces 52, 57 and the distance between them. Its projection pattern is used as a feedback signal for adjusting for alone deciding the relative positions between the adjacent components 50, 55, or attaining both or one side of required relative orientation and isolation distance between these components 50, 55.
