Abstract

Abstract The invention proposes a device designed for separating IC lead frames, boards, etc., piece by piece, and loading them continuously, and composed of a work stocker which holds laminated work of strips; a work-pressing mechanism which continuously presses the work within the work stocker; a separating mechanism which strips away the laminated work piece by piece from the lowest part thereof; and a pusher mechanism which pushes outside the stripped work from the work stocker; and wherein the separating mechanism is installed with a detector which finds out double sheets of the strips and stops operation of the pusher; and the separator is installed at its work exit end with a positioning pin of go-in-and-out of a taper shape which positions end points of the work pushed out by the pusher.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 113 words
A frame separator, composed of a work stocker which holds laminated work of strips; a work-pressing mechanism which continuously presses the work within the work stocker; a separating mechanism which strips away the laminated work piece by piece from the lowest part thereof; and a pusher mechanism which pushes outside the stripped work from the work stocker; and wherein the separating mechanism is installed with a detector which finds out double sheets of the strips and stops operation of the pusher; and the separator is installed at its work exit end with a positioning pin of go-in-and-out of a taper shape which positions end points of the work pushed out by the pusher.
Claim 2
Dependent Claim 113 words
A frame separator, composed of a work stocker which holds laminated work of strips; a work-pressing mechanism which continuously presses the work within the work stocker; a separating mechanism which strips away the laminated work piece by piece from the lowest part thereof; and a pusher mechanism which pushes outside the stripped work from the work stocker; and wherein the separating mechanism is installed with a detector which finds out double sheets of the strips and stops operation of the pusher; and the separator is installed at its work exit end with a positioning pin of go-in-and-out of a taper shape which positions end points of the work pushed out by the pusher.
Claim 3
Dependent Claim 22 words
A device as claimed in claim 1, wherein the work-pressing mechanism goes down by its own weight and presses the laminated work.
Claim 4
Dependent Claim 19 words
A device as claimed in claim 1, wherein the amount of pushing the work by the pusher is adjustable.
Claim 5
Dependent Claim 22 words
A device as claimed in claim 1, wherein a detector finds out double sheets of the strips by detecting changes of inductance.
