Abstract
A welding joint recognizing sensing device based on a surface auxiliary light source is characterized in that a surface facula laser and a charge coupled device (CCD) video camera are fixedly connected in an aluminum alloy main frame. The optical axis of the surface facula laser and the optical axis of the CCD video camera form an angle of 18 degrees to 25 degrees, and a filtering piece, a partial positive piece and a light reducing piece are sequentially arranged at the front end of the CCD video camera. The welding joint recognizing sensing device has the advantages of being capable of achieving thin plate welding and characteristic recognition of welding joint characteristic information and meeting requirements of an intelligent welding robot for the sensing device due to the fact that an obtained welding joint is clear in image and contains a large amount of welding joint characteristic information quantity. The welding joint recognizing sensing device is especially suitable for high quality full automatic welding and has high practicability.
Description
Technical field
The utility model relates to a kind of weld seam recognition sensing device, relates in particular to a kind of weld seam recognition sensing device based on face property secondary light source.
Background technology
At present, the sensor that is used for position while welding identification has feeler, arc sensor, electromagnetic sensor, ultrasonic sensor and vision sensor.Compare with other sensors, vision sensor has that the information content of providing is abundant, sensitivity and certainty of measurement is high, the anti-electromagnetic field interference performance is strong and with advantages such as workpiece is contactless.Along with the continuous development of material science, alloy material has all had significant raising on intensity and toughness, for plate sheet welding replaces common sheet material welding reliable guarantee is provided.Simultaneously because plate sheet welding in the superiority that reduces on the product weight, makes it have a wide range of applications.
During plate sheet welding, because surface of the work is smooth, can produce reflectively, the weld seam characteristic information is often flooded by arc light, brings difficulty for the picked-up of image feature information; During plate sheet welding, speed of welding is fast, and the span of weld seam is little, narrow.What research both at home and abroad was ripe at present is to adopt the visual sensing mode of linear laser as secondary light source; The distortion of this mode laser rays in the commissure is little; The characteristic information amount of obtaining is few; Can handle to image and bring very big difficulty, the weld joint tracking precision when being difficult to guarantee plate sheet welding influences welding quality.
Summary of the invention
The purpose of the utility model has been to provide a kind of weld seam recognition sensing device based on face property secondary light source, and this sensor can collect that information content is many, the evident characteristic weld image.
The present invention realizes like this; It comprises aluminium alloy main frame, face property light spot laser device, ccd video camera, optical filter, polaroid, light damping plate; It is characterized in that being fixed with in the aluminium alloy main frame face property light spot laser device and ccd video camera; The optical axis of said property light spot laser device and the optical axis 18o ~ 25o of ccd video camera, the front end of said ccd video camera is provided with optical filter, polaroid and light damping plate successively.
The technique effect of the utility model is: can realize that to plate sheet welding, the weld seam characteristic information carries out feature identification, and the weld image that obtains is clear, to comprise weld seam characteristic information amount many, satisfies the demand of intelligent welding robot to sensing device.The high-quality that this sensor is particularly suitable for thin plate automatically welds, and has very high usability.
