Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to an intelligent vision laser cutter that is resistant to strong light. Background Technology

[0002] Laser cutting involves focusing a laser beam emitted from a laser source into a high-power-density beam via an optical path system. This beam irradiates the workpiece surface, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and workpiece moves, a kerf is formed, achieving the cutting purpose. During cutting, a high-resolution camera captures the kerf morphology, burrs, and slag residue, and AI algorithms instantly identify quality anomalies (such as notches or overheating), achieving a defect detection rate of over 99%. Visual algorithms automatically compensate for surface fluctuations (such as sheet deformation or unevenness) to ensure the laser focus remains at the optimal cutting depth. However, current cameras mostly provide direct observation, and prolonged exposure to strong light can cause physical damage to the camera's photosensitive components, leading to permanent black spots, color differences, or streaks in the images. Furthermore, close-range direct observation by the camera causes vaporized material from laser cutting to adhere to the camera's objective lens, resulting in difficult and costly cleaning and maintenance. Therefore, improvements are needed. Utility Model Content

[0003] Therefore, it is necessary to provide an intelligent vision laser cutter that is resistant to strong light in order to address the above problems.

[0004] A smart vision laser cutter with strong light protection includes a laser cutting body, camera components and a mirror assembly. The two camera components and the mirror assembly are mirror-symmetrically installed on both sides of the laser cutting body. The mirror assembly is located below the camera components. A reflector is installed in the mirror assembly. The mirror angle of the reflector is adjustable. The camera optical path of the camera component is directly opposite the mirror surface of the reflector.

[0005] Preferably, the mirror assembly further includes a mounting bracket and a rotating shaft. The mounting bracket is U-shaped, with its open end connected to the side wall of the laser cutting body. The rotating shaft is movably mounted in the mounting bracket via a bearing and is connected to a reflector to drive the reflector to rotate and adjust the reflection angle.

[0006] Preferably, the lens assembly further includes a micro motor, which is mounted on a mounting bracket and its output end is connected to a rotating shaft to drive the rotating shaft to rotate.

[0007] Preferably, a dielectric film is disposed on the mirror surface of the reflector.

[0008] The advantages of this invention are: by using a rotatable reflector to match and align the laser cutting body's working position, the camera is prevented from shooting directly at the camera, thus avoiding strong light being reflected into the camera and preventing overload damage to the photosensitive components inside the camera.

[0011] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0012] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0014] like Figures 1-2As shown, an intelligent vision laser cutter with strong light protection includes a laser cutting body 1, camera components 2, and a mirror group 3. The two camera components 2 and the mirror group 3 are mirror-symmetrically mounted on both sides of the laser cutting body 1. The mirror group 3 is located below the camera components 2, and a reflector 31 is installed inside the mirror group 3. The mirror angle of the reflector 31 is adjustable. The optical path of the camera 21 of the camera component 2 is directly opposite the mirror surface of the reflector 31. Specifically, the laser cutting body 1 serves as the main body, emitting a high-power laser at its output end for laser cutting of the workpiece. Two camera components 2 and a mirror group 3 are installed on both sides of the laser cutting body 1. The camera 21 in the camera component 2 is tilted downwards. The mirror group 3 is installed at the output end of the laser cutting body 1, located below the camera 21, to reflect the cutting operation of the laser cutting body 1 into the camera 21 for recording, acquiring the cutting point process status, and adjusting parameters such as the output power of the laser cutting body 1 in real time. The two camera components 2, together with the lens group 3, can capture images of the laser-cut area from multiple angles. For specific optical path details, please refer to [reference needed]. Figure 2 The dotted lines indicate different areas of the work zone, facilitating the control panel's adjustment of parameters such as the power path of the laser cutting body 1. The reflection from the central mirror 31 prevents the camera 21 from directly entering the laser cutting body 1 at close range, avoiding lens contamination, reducing cleaning frequency, and effectively extending the camera's lifespan. Furthermore, the mirror 31, being rotatable, allows for manual or automatic rotation during high-power laser cutting to prevent strong light from reflecting back into the camera 21 along the original optical path. This prevents overload and damage to the camera's internal photosensitive components.

[0015] like Figures 1-2 As shown, the mirror assembly 3 also includes a mounting bracket 32 ​​and a rotating shaft 33. The mounting bracket 32 ​​is U-shaped, with its open end connected to the side wall of the laser cutting body 1. The rotating shaft 33 is movably mounted inside the mounting bracket 32 ​​via bearings and is connected to the reflector 31, used to rotate the reflector 31 to adjust the reflection angle. Specifically, the mounting bracket 32 ​​is fixed to both sides of the laser cutting body 1 by welding. The rotating shaft 33 rotates within the hollow area of ​​the mounting bracket 32, thereby adjusting the mirror surface direction of the reflector 31. This prevents strong light from being reflected back into the camera 21 along the original light path when the laser cutting body 1 is operating at high power, thus avoiding damage to the photosensitive components inside the camera 21.

[0016] like Figures 1-2As shown, the mirror assembly 3 also includes a micro motor 34, which is mounted on the mounting bracket 32. Its output end is connected to the rotating shaft 33 to drive the rotating shaft 33 to rotate. Specifically, when the micro motor 34 drives the rotating shaft 33 to rotate, it can drive the reflector 31 to rotate, thereby adjusting the angle of the reflector 31. This facilitates cleaning of the reflector 31's surface and prevents the strong light generated during high-power laser cutting of the body 1 from being directly reflected into the camera 21, effectively ensuring the lifespan of the photosensitive components inside the camera 21.

[0017] Specifically, a dielectric film is provided on the surface of the reflector 31, which is suitable for lasers of a specific wavelength and improves reflectivity.

[0018] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
