The birth of fiber laser cutting machines is mainly to improve work efficiency improve cutting accuracy. But high efficiency high precision are far being achieved by human operation. How to adjust the optical path of the fiber laser cutting machine during the application process? Here is an introduction to the principle of optical path adjustment of fiber laser cutting machine:
After adjusting the angles of the three mirrors, the light paths are finally parallel, the laser head is hit at the same point at any position, finally focused on the center of the focusing lens. The method for fiber laser welding machine manufacturers to adjust the optical path of fiber laser cutting machine: (adjust the current to 4-5mA)
1. The manufacturer of the laser welding machine checks whether the laser can hit the reflector. (The method uses a plastic sheet to cover the first mirror, press the TEST button to see the laser dot position) If the laser cannot hit the lens, adjust the lens position.
2. Check whether the laser can hit the second third mirrors. If , adjust the M1, M2, M3 screws behind the upper mirror.
3. Paste at least two layers of double-sided tape at the light entrance of the laser lens barrel (as shown in Figure 6-3 of the laser lens barrel), move the laser head to the upper right corner of the table press the TEST button on the control panel to hit a laser point.
4. Move the laser head to the upper left corner hit another laser spot to see if it can be in the same position as the spot hit on the upper right corner. If , adjust the M1, M2, M3 screws of the second mirror. Make it the same position as the dot on the upper right corner.
5. Move the laser head to the lower left corner to see if the dot is at the same position as the upper right corner, adjust the second reflector.
6. Repeat the adjustment as described in d e above, the three laser dots hit the same position.
7. Check whether the focus is in the center: Put a mirror below the focusing lens, place a transparent plastic sheet close to the lens barrel under the lens barrel (ie, hold it in hand) press the TEST button to hit the laser. The fiber laser welding machine equipment looks at the laser. Whether the point can hit the center of the focusing lens. Hand-held plastic sheet should be burned by laser. Do put your hands within the vertical plane of the lens.
Note: When adjusting the light path, adjust the M1, M2, M3 screws of the frame angle each time, observe the changes in the light path.
