Claim of US Patent No. 10,694,648

1. A system for placement of a pin, which comprises a pin head and a pin body, into at least one hole fabricated on an article, the system comprising:a moveable base on which the article having a surface carrying the at least one hole is located;
a press head for holding the pin and inserting the held pin into the at least one hole on the article;
a first vision system installed to capture a first image illustrating planar arrangement of a designated hole on the article;
a second vision system installed with an optical assembly to capture a second image and a third image capable of illustrating a center axis of the held pin in relation to a center axis of the press head respectively from two vantage points which are substantially perpendicular to one another at a vertical plane;
a computing unit being configured to
assign a relative coordinate consisting of a X-value and a Y-value being correspondingly indicative to an actual location of the at least one hole at a X-axis and a Y-axis on the surface,
compute relative deviations presented between the held pin and the designated hole at the X-axis and the Y-axis, the relative deviation at the X-axis being computed by way of calculating an offset of the at least one hole and an offset of the pin at the X-axis, the relative deviation at the Y-axis being computed by way of calculating an offset of the at least one hole and an offset of the pin at the Y-axis, and
move the base to adjust the article in a manner correcting or compensating the computed deviation prior to inserting the held pin into the at least one hole.
