The light-emitting lens at the front of the optical head assembly is just a lens, which is completely useless for our conversion. The real light-emitting element-the laser diode is located inside the optical head assembly. Because the screws used to fix the laser diodes are too small, it is difficult to tighten them one by one. In any case, the optical drive is destined to be scrapped. Just use a screwdriver to boldly pry it open. First pry open the glued lens part, you can see the protective cover of the laser diode inside the optical head assembly, then pry open the metal plate that fixes the protective cover to easily take it out. Finally, weld the two solder joints on the tail of the unwelded laser diode protective cover, and then take out the laser engraver diode for use.
The first step is of course to remove the optical drive. Turn the optical drive upside down, use a Phillips screwdriver to loosen the four corner fixing screws, after removing the bottom cover, you will see two integrated circuit boards, one large and one small. Then pry open the buckles on both sides of the large circuit board, and unplug the various cables on the front and back sides of the circuit board to lift it up. The so-called bald head is located under the lower circuit board and between two metal sliding rods. At both ends of the slide bar, you can find the fixed screws. You only need to loosen the screw at the bottom of the left slider. The slide bar and the bald head are removed from the optical drive together.

Finally, weld the two solder joints on the tail of the unwelded blue laser pointer diode protective cover, and then take out the laser diode for use.
Now take out the laser module you bought, separate its head and rear part, remove the lens and spring of the laser module head, replace the original diode with the laser diode just removed, pay attention to the two poles of the positive and negative laser diodes respectively The positive pole and negative pole of the socket correspond. After fixing the diode, put the lens back in place and bounce back to the head of the laser module.
