Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipe cutting auxiliary equipment, in particular to a protective weld identification device for laser pipe cutting equipment. Background Art
[0002] Steel pipes are usually divided into seamed steel pipes and seamless steel pipes. In actual production applications, seamed steel pipes are widely used due to their low production cost. The weld seam of the seamed steel pipe has different mechanical properties from the normal pipe wall area due to welding, and the thickness of the pipe wall will also increase. Under the same laser cutting parameters, the weld seam may not be completely cut, affecting the quality of the processed product. In order to eliminate the problem of the weld seam affecting the cutting quality and ensure the quality of the processed product, the weld seam of the steel pipe is effectively identified by adding image recognition technology. Then, during the processing, when the weld seam is cut, the cutting parameters are changed to ensure the cutting quality.
[0003] Existing weld recognition devices have defects: the weld recognition device is relatively independent of the laser head, and the distance of the weld recognition device relative to the weld to be photographed cannot be changed; during the processing and cutting process, the laser head will generate a large amount of smoke and sparks at the cutting position, causing local temperature increases, damaging the camera and reducing its service life; during the shooting process, the weld recognition area lacks light guidance, and the recognized image is blurry. Utility Model Content
[0004] In order to improve the defects of the weld identification device in the above-mentioned background technology, the utility model provides a protective weld identification device for laser tube cutting equipment.
[0005] The utility model provides a protective weld identification device for laser pipe cutting equipment, which adopts the following technical solutions:
[0006] A protective weld identification device for laser tube cutting equipment is installed on one side of the laser head mounting plate, and includes a pneumatic slide, a camera and a lighting lamp. The bottom of the camera is installed on the camera mounting plate, and the camera mounting plate is fixedly mounted on the pneumatic slide. A protective component is provided on the outside of the camera; an adjustment component for adjusting the angle and position of the lighting lamp is provided on the back of the lighting lamp, and the end of the adjustment component is fixed on one side of the camera mounting plate; the camera and lighting lamp are both aimed at the cutting area.
[0007] Preferably, the bottom of the pneumatic slide is mounted on a pneumatic slide mounting plate, the pneumatic slide mounting plate is fixedly mounted on one side of the laser head mounting plate, and the pneumatic slide includes a slide rail and a slider slidably mounted on the slide rail.
[0008] Preferably, the protective assembly includes a shield and a cover plate, the shield is arranged on the outside of the camera body, and the cover plate is arranged at the image recognition end of the camera. The back of the cover plate is hinged to one end of the cylinder, and the other end of the cylinder is hinged to the connecting bracket fixed on the outside of the shield.
[0009] Preferably, the adjustment assembly includes an x-link, a y-link and a rotating block for adjusting the angle of the lighting lamp. The rotating block is hinged on the back of the lighting lamp. One end of the x-link passes through the fixed mounting hole on the upper part of the rotating block. The x-link and the y-link are staggered and passed through the mounting hole inside the connecting block and are fixed by bolts. The end of the y-link is fixed on one side of the camera mounting plate.
[0010] In summary, the present invention has the following beneficial technical effects:
[0011] 1. The pneumatic slide moves with the movement of the laser head. When weld identification is required, the camera and lighting are moved down by the pneumatic slide. The image recognition end of the camera is closer to the weld to be photographed, making the identification clearer.
[0012] 2. During the cutting process, the laser head will generate a lot of smoke and sparks at the cutting position, and the local temperature will rise. By setting up protective components to protect the camera, the service life of the camera can be effectively extended and the production cost can be reduced.
[0013] 3. The lighting lamp illuminates the area where image recognition is required to assist the camera in image recognition. The angle and position of the lighting lamp can be adjusted by adjusting the components to meet the image recognition work at different angles and positions. BRIEF DESCRIPTION OF THE DRAWINGS
