[0024] The method of the utility model is further described in detail below with reference to the accompanying drawings.
[0025] Reference Figure 1 Figure 2 shows a multi-axis coaxial laser marking device, comprising a housing 5, a laser 10 being fixedly mounted on one end of the housing 5, a coaxial lens holder 6 being fixedly mounted on the outer surface of the housing 5, a mounting bracket being provided on the upper end of the coaxial lens holder 6, and a camera 7 being fixedly mounted on the outer surface of the mounting bracket, the shooting direction of the camera 7 being vertically oriented, a reflective one-way mirror 11 being mounted on the inner side of the coaxial lens holder 6, the reflective one-way mirror 11 being located on one side of the laser 10 and tilted at a forty-five degree angle, and the shooting angle of the camera 7 being coaxial with the laser beam of the laser 10. During laser marking, the laser generated by the laser 10 is reflected by the tilted reflective single-sided mirror 11 and then directed vertically downward. At this time, the laser can perform effective marking operations. Since a camera 7 is installed at the upper end of the coaxial lens bracket 6, the shooting angle of the camera 7 is vertically downward, and the shooting angle is coaxially distributed with the marking laser. This can capture the marking image in real time during the marking process and perform mark detection operations. The efficiency and accuracy of marking are effectively improved. At the same time, the camera 7 can be used to detect the position of the object to be marked, which can ensure that the marking positions of multiple objects are consistent.
[0026] Reference Figure 1 2, a first light source 8 is fixedly mounted on the lower end of the coaxial lens bracket 6. The first light source 8 is in a circular shape. A plurality of second light sources 9 are fixedly mounted on the lower end of the coaxial lens bracket 6. The plurality of second light sources 9 are arranged in a circular array outside the first light source 8. The first light source 8 can be used to provide light for visual detection, and the second light source 9 can be used for positioning lighting operations.
[0027] Referring to Figure 1, a first linear module 2 is provided on the outside of the box body 5, and a second linear module 3 is fixedly installed on the movable end of the first linear module 2. The first linear module 2 and the second linear module 3 are vertically distributed, and a connecting plate 4 is fixedly installed on the movable end of the second linear module 3. The box body 5 is fixedly installed at one end of the connecting plate 4, and a supporting base 1 is provided at the lower end of the first linear module 2. Through the arrangement of the first linear module 2 and the second linear module 3, the laser mechanism can perform biaxial position movement, can flexibly adapt to different laser marking operations, and the entire marking operation has a high degree of automation and strong overall practicality.
[0028] Working principle: When in use, first install the device at the specified position, and then place the object to be marked at the marking position. At this time, the second light source 9 performs positioning lighting, and the camera 7 performs the marking position shooting operation. Then use the first linear module 2 and the second linear module 3 to adjust the position of the marking mechanism so that the marking mechanism is at the specified position, and then start the laser 10. The laser generated by the laser 10 is reflected by the inclined reflective single-sided mirror 11 and then points vertically downward. At this time, the laser can perform effective marking operations. According to the marking pattern, the first linear module 2 and the second linear module 3 perform biaxial position adjustment on the laser marking mechanism. Since the shooting angle of the camera 7 is vertically downward, the shooting angle is coaxially distributed with the marking laser. This can capture the marking picture in real time during the marking process and perform the marking detection operation, which effectively improves the efficiency and accuracy of marking.
[0029] The real-time examples of this specific real-time method are all preferred real-time examples of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
