I independently conduct the Opto-mechatronic (mechanical, electrical, and optical) integration task of this dual-laser automated laser-foil-printing system from system design, building, alignment, and testing to automate these steps (supply foil, transport the clamping plate, proceed IR laser spot welding, proceed pattern welding, proceed UV laser contour cutting, separate foil from fabricated layer, and polish to flatten part surface). The Opto-mechatronic System Integration includes integrating IPG IR & Coherent UV lasers, X-Y-Z stages, Galvo-Scanner, Dual Motors using LinuxCNC (G-code based) as the master software (control I/O signals, motion stages movement, and Laser On/Off) and LaserDESK as the Slave software (control the Galvo-Scanner).

The control logic layout is shown in Fig. 1. In Fig. 1, the electronics box was build This automated LFP system is shown in Fig. 2.

Mechanical Design/Assembly:

In this automation system, I independently conduct design, order, assemble mechanical components to demonstrate my CAD model ability as shown in Fig. 1.

Electronics Aspect:

In this automation system, I independently conduct design, order, assemble all components to in the electronics box including 24V power supply, X-Y-Z Motor Driver, Foil-Supply Driver, Mesa Control Card Boards (7i76, 6i25, and 7i83), Emergency Button, Power On/Off Button to demonstrate my electronics integration ability as shown in Fig. 2.

Optical Aspect:

In this automation system, I independently conduct the alignment of the UV laser beam and the dual-laser beams to make sure the coordinate system (X-Y axises) of dual laser beams are aligned accurately as shown in Fig. 3.
