The following describes the method of adjusting the fault light path of the common laser engraving machine:
A: Adjust the laser current to be less than 5, so that the laser power is not too strong; Two: Place the blackout paper in front of the first place.19 20 25 27 30 38.1 50.8 Si laser reflective mirror and lightly press the test switch by hand (press and immediately release, you can see the stained laser dot on the blackout paper), see if the spot falls off first can be found, this step is complete. If you can't hit19 20 25 27 30 38.1 50.8 Si laser reflective mirror or deflected, you need to adjust the position or height of the laser tube to meet the above criteria. Three: optical path adjustment between the first19 20 25 27 30 38.1 50.8 Si laser reflective mirror, and the second19 20 25 27 30 38.1 50.8 Si laser reflective mirror. Place the laser paper first in front of the second.19 20 25 27 30 38.1 50.8 Si laser reflective mirror, push the guide to position (a) in the figure and click a test switch to see the dot position. Next, pull the rail to position (b) and click the test switch to see if the positions of the two points coincide. If it is in coincidence and spot position19 20 25 27 30 38.1 50.8 Si laser reflective mirror, optical path between19 20 25 27 30 38.1 50.8 Si laser reflective mirror 1 and 2 are right; if it's no coincidence, it needs to be adjusted by adjusting the adjusting screw on its frame.19 20 25 27 30 38.1 50.8 Si laser reflective mirror To adjust the two points together 1. Four: adjusting the optical path in between. 19 20 25 27 30 38.1 50, 8 Si laser reflective mirrors 2 and 3. First, position the laser head in figure (c) and put the dimming wedding in front of the small hole of the laser head / press the test button to look at the light shift, then press the head. Set it to (d) and press it again. Test the switch and see if the two pressures overlap. If the two points are in the small hole of the laser head, the light path is correct. If it is not the same spot, you need to adjust the set screw 2 on the back of the frame to adjust. criteria above. Note: The optical path adjustment principle between 19 20 25 27 30 38.1 50.8 Si laser reflective mirror 1, 2 and 2, 3 is the same. Five: optical path adjustment between19 20 25 27 30 38.1 50.8 Si laser reflective mirror 3 and 4 (one step closer) before19 20 25 27 30 38.1 50.8 Si laser reflective mirror, glossy paper under the laser head place it and click the test switch to see if the dot is in the middle of the blackout paper. . If it is exactly midway, the optical path is positive; if the spot is correct, the laser tube is too low; if the spot remains, the laser tube is too high; In both cases, it is necessary to adjust the height of the laser tube to solve it. If the spot is inside or outside, you need to adjust the optical path by moving the position of the laser head (there are three screws on the laser head, they can be adjusted inside and outside of the laser head). Attach the lens, the adjustment of the light path is complete.
Note: Adjustment requires certain basic knowledge, such as: light reflection principle, etc., the first time debugger needs to follow the instructions and consult technical personnel if necessary. In addition, the laser has a certain degree of burning and is an invisible gun, so be sure to pay attention to safety during blackout.
