In order to improve work efficiency and cutting accuracy. With the birth of optical fiber laser cutting machine. However, high efficiency and high precision are far from manual operation. How to adjust the optical path of the optical fiber laser cutting machine during use? The following is an introduction to the principle of optical path adjustment of optical fiber laser cutting machine:
By adjusting the angle of the three mirrors, the optical path is finally parallel, the laser head hits the same point at any position, and finally focuses on the center of the focusing lens. Adjustment method of optical path of optical fiber laser cutting machine: (adjust the current to 4-5mA)
1. Check whether the laser will impact the reflector. (To block the first reflector with a plastic sheet, press the TEST key to check the position of the laser point.) If the laser cannot reach the lens, adjust the lens position.
2. Check whether the laser will hit the second and third mirrors. If not, please adjust the M1, M2 and M3 screws behind the reflector at the previous level.
3. Stick at least two layers of double-sided tape (as shown in Fig. 6-3) at the light inlet of the laser lens tube, move the laser head to the upper right corner of the workbench, press and hold the TEST key on the control panel, and then hit the laser point.
4. Move the laser head to the upper left corner and hit another laser point. Observe whether it is in the same position as the spot in the upper right corner. If the position is different, please adjust the M1, M2 and M3 screws of the second reflector. Make the point you hit the same as the point in the upper right corner.
5. Move the laser head to the lower left corner, check whether the observation point is the same as the upper right corner, and then adjust the second reflector.
6. Repeat the adjustment described in d and e. After all, three laser spots hit at the same location.
7. Check whether the focus is in the center: place a mirror vertically under the focusing mirror, place the transparent plastic sheet near the square of the lens barrel (i.e. hold it), press the TEST key to hit the laser, and see whether the laser hits the center of the focusing lens. Be careful of laser burns when holding the plastic sheet. Do not place your hands on the vertical plane of the lens.
Note: When adjusting the optical path, each time the adjustment range is very small, adjust the M1, M2 and M3 screws of the mirror frame angle, and observe the changes of the optical path.
