Memory Plane Terminal Welder

This device automatically aligns and welds together the terminals of stacked memory planes.

Several terminal welding heads simultaneously align and weld pairs of terminals together. Each welding head has aligner 12. This is moved inwardly towards frames 14 and 16 of the memory planes and is positioned alongside a pair of terminals 18 and 20. Then, aligner 12 is moved towards the two terminals so as to exert pressure against the sides of both the terminals. These are forced out of their normal positions into a position where they are held aligned one under the other by the force aligner 12 exerts on them.

In this aligned position, both terminals 18 and 20 are located between spaced-apart welding electrodes 22 and 24. These are normally kept spaced apart by flexible tube 26. This is filled with air to force the welding tips of electrodes 22 and 24 away from each other around pivot point 28. Once terminals 18 and 20 are aligned between electrodes 22 and 24, tube 26 is evacuated. Tubes 30 and 32 are filled with air to force the tips of electrodes 22 and 24 together and into contact with terminals 18 and 20. Then a welding pulse is applied to electrodes 22 and 24 to complete the weld.

After the completion of the welding pulse, electrodes 22 and 24 are separated by evacuating tubes 30 and 32 and filling tube 26. Also, aligner 12 is moved away from frames 14 and 16 so that it is no longer along side terminals 18 and 20. This allows the weldi...
