Abstract

An advanced parallel seam-sealing system which includes a control console, computer deck, electronic keyboard and welding robot for automatically sealing electronic and other component packages. The welding robot is designed to have seven (7) degrees of motion. Parallel arms having roller electrodes move independent of each other in horizontal and rotational directions to continuously operate on a package or matrix of packages which are supported on a rotary table that has vertical, longitudinal and rotary motion. Six of the motions are driven through computer programmed commands and the vertical rotary table motion is electromechanically controlled and represents the seventh degree of motion. The multiple degrees of freedom allow the system to be used for sealing of multiple arrays of packages by this parallel seam-sealing technique, in a reliable, precise and fast operation.

Dependent claims

An advanced parallel seam-sealing system for sealing a matrix of packages in a single operation comprising:

A control console having a CRT display for viewing of a menu-driven program, menu select keys for selecting said menu-driven program and controlling electro-mechanical systems of said advanced parallel seam-sealing system, AC and DC power parallel seam-sealing system;
A computer deck for inserting therein and running of a disk storing a computer program with package data which controls said electro-mechanical system of said advanced parallel seam-sealing system, said package data consisting of package dimensions, welding parameters and array configurations which may be viewed on said CRT display;
An electronic keyboard connected to said computer deck for keying in said computer programs, said package data, and input data which controls said electro-mechanical systems;
A welding robot having seven (7) degrees of motion consisting of a right arm latitudinal motion independent of a left arm latitudinal motion, right arm rotary motion independent of left arm rotary motion, circumferential rotary table motion, vertical rotary table motion and longitudinal rotary table motion, all of which are controlled by said computer programs, except for said vertical rotary table motion;
A structural means of supporting and protecting said welding robot;
A control means for operation of said electromechanical systems of said welding robot.
