Device and method for alignment of parts for laser welding

A device for alignment of parts for welding, the device comprising:

• a bottom welding fixture and a top welding fixture, the top welding fixture moveable from an engaged position having the top welding fixture engage the bottom welding fixture, to a disengaged position having the top welding fixture spaced from the bottom welding fixture;
• the bottom welding fixture having:
• a profile providing an outline of a position of the parts to be welded;
• a plurality of fixed locating pins positioned along a peripheral edge of the profile limiting movement of the part to be welded in a first axis and a second axis, the first axis being perpendicular to the second axis;
• and
• at least a pair of alignment block assemblies positioned along the peripheral edge of the profile to actuate movement of the part to be welded in the first axis and the second axis;
• each of the alignment block assemblies having an alignment block moveable from a first position having the alignment block spaced from the peripheral edge of the profile to a second position having the alignment block proximate to the profile;
• and
• an actuator coupled to the top welding fixture or the bottom welding fixture to actuate movement of the alignment block from the first position to the second position upon engagement of the top welding fixture to the bottom welding fixture.
