Description

Technical Field

[0001] The utility model relates to the technical field of laser scanning devices, in particular to a laser scanning device. Background Art

[0002] The laser marking system consists of a laser source, a laser scanning galvanometer, a laser focusing field lens, and a laser controller. The laser source generates a laser beam, which is deflected by the scanning galvanometer at a certain angle (in the X and Y directions). The laser beam is then focused by the focusing field lens, so that the laser is applied to the object within a certain range and according to certain graphic requirements, achieving surface marking, printing, or welding and cutting with a certain depth.

[0003] According to the announcement number "CN205733432U," a new laser scanning device with reflective lens burn-in protection includes a laser reflective lens, a mirror frame located below the laser reflective lens, a temperature detector, a power detector, and a coated reflective surface connected to the laser reflective lens, a power detector located above the temperature detector, and a laser reflective lens located between the power detector and the coated reflective surface. A scanning motor is connected to the mirror frame, and both ends of a connecting cable are connected to the scanning motor and a motor driver board, respectively. The motor driver board is located to the right of the scanning motor, and a laser controller is located to the right of the motor driver board. A laser source is located above the laser controller, and a laser beam is located between the laser source and the coated reflective surface. This utility model actively protects the reflective lens coating from damage due to overheating, thereby extending the service life of the galvanometer mirror.

[0004] However, in actual use, the overall structure lacks protection when the laser scanning device is not in use, and cannot be adjusted according to the required distance. Therefore, improvements have been made based on the above-mentioned problems. Utility Model Content
