US Patent:

45064423, Mar 26, 1985

Filed:

Sep 29, 1982

Appl. No.:

6/428042

Inventors:

Donald R. Alzmann - East Islip NY
Michael Angelo - East Islip NY
Paul R. Waldner - Wantagh NY

Assignee:

Lenkeit Industries, Inc. - Farmingdale NY

International Classification:

H05K 336
B65G 5702

US Classification:

29830

Abstract:

Apparatus for stacking a plurality of laminate layers in registered superposed relation to enable the layers to be joined to form a composite board comprising a table having a surface on which a plurality of laminate layers can be successively stacked in aligned superposed relation on pins slidably received in respective apertures in the table. The pins rest on support members which are carried on a lower support table mounted beneath the surface of the table on which the laminate layers are stacked. The lower support table is raised relative to the stack of laminate layers after successive laminate layers have been placed on the pins so that a given projection of the pins from the laminate layers will be obtained.

Appl. No.:

6/668137

International Classification:

H04N 718

US Classification:

358101

Abstract:

Method and apparatus for effecting operations, such as punching holes in sheets of material at precise locations thereon. Each sheet has a reference marking thereon and is placed on a receiver one by one and is held in fixed position on the receiver. A T. V. camera views each sheet to detect the reference marking thereon and a visual display of the marking is produced on a T. V. monitor. Also produced on the monitor is a cross-hair grating with a coincident shaded box. The cross-hair grating is first aligned with a marking reference on a master sheet to establish a fixed relation between the cross-hair and the marking reference on the master sheet and thereby between the cross-hair and the operating system, for example, the punches for punching holes in the sheets. The master sheet is removed and the sheets to be punched are placed one by one on the receiver which is moved to align the reference marking on each sheet, as viewed on the monitor with the cross-hair grating thereon.

Multiline Technology, Inc. - Farmingdale NY

International Classification:

H04N 718

US Classification:

358101

Abstract:

The method includes locating a target on a printed circuit board laminate having a circuit pattern etched thereon and utilizing the target to locate the laminate in a punching device. Preferably two such targets are employed and the laminate is adjusted in the X and Y directions as well as rotationally to bring the target into prescribed relationship with reference markings whereby to locate the holes precisely in the laminate whereby to facilitate stacking of the same. In related apparatus two television cameras are employed to operate with two targets to feed data into a microprocessor which generates signals to cause an alignment of the laminate to be punched. With respect to punching mechanisms special techniques are employed to locate the centers of the targets so that these centers can be aligned with cross hairs to take into account the deviations possible in the configurations of the targets.
