The optical system is divided into: Suzhou Fleet laser light guiding system and laser generating system.

The laser light guide system consists of a, b and c three-stage mirrors and an adjustable focusing mirror;

The laser generation system consists of CO2 laser and laser power supply.

The optical path is a light guide system, and the fleet laser adopts a flying optical path. The complete optical path is composed of laser tube, mirror frame (A, B, C), focusing mirror and corresponding adjusting device, which is the core part of laser cutting machine.

The quality of light path adjustment is directly related to the cutting effect, so it should be adjusted patiently and carefully.

3. Adjustment of light path

( 1)

(1) Adjust the first lamp

Stick the transparent adhesive tape on the dimming target hole of the reflector A, manually jog the light, and finely adjust the base of the reflector A and the laser tube bracket so that the light hits the center of the target hole, and be careful not to block the light;

(2) Adjustment of the second lamp

Move the reflector B to the far end position, use a piece of cardboard to emit light from near to far, and guide the light into the cross light target. Because the far beam is in the target, the near end must be in the target, and then adjust the consistency between the near end and the far beam, that is, how the near end deviates, so that the cross is in the same position at the near end and the far beam. Far) means that the light path is parallel to the Y-axis guide rail.

(3) Adjustment of the third light (note: the cross divides the light spot equally)

Move the mirror c to the remote position, put the light guide into the light target, and shoot the target once at the entrance and once at the remote position. Adjust the position of the cross to the same position as the cross at the near point, indicating that the beam is parallel to the X axis. At this time, if the light path is inward or outward, it is necessary to loosen or tighten M 1, M2 and M3 on the frame B until they are split in two.

(4) Adjustment of the fourth lamp

Stick a piece of transparent tape on the light outlet so that the light outlet leaves a circular mark on the tape. Touch the adhesive tape to observe the position of the small hole, and properly adjust M 1, M2 and M3 on the frame C until the light spot is round and positive.

(2) Measurement method of focal length: put an iron sheet under the nozzle, gently push it to shine all the time, lift the lens barrel, and lock the screw when the light hits the iron sheet. At this time, the distance from the surface of the iron sheet to the nozzle is the focal length (about 4 ~ 6mm).
