Anti-splashing device and method used for welding sensor

Abstract

The invention discloses an anti-splashing device and method used for a welding sensor. The anti-splashing device comprises a base, and a lens light outlet hole and a laser device light outlet hole are formed in the base. A lens blocking piece and a laser device blocking piece are arranged at the positions, on the inner sides of the lens light outlet hole and the laser device light outlet hole, of the base, and a rocking handle and a swing rod are arranged between the lens blocking piece and the laser device blocking piece. The swing rod is engaged with a steering engine output shaft gear, drives the rocking handle to rotate and converts motion into reciprocating linear motion of the lens blocking piece and the laser device blocking piece in the base, and therefore opening and closing of the lens light outlet hole and the laser device light outlet hole are achieved. The device has the advantages of being compact in structure, small in occupied space and capable of achieving self-cleaning. In the using process of a laser welding seam sensor, the influence of splashed welding slag particles on the welding sensor can be effectively blocked. The structure can be applied to a line structured light laser sensor, a surface structured light laser sensor, a binocular sensor and other occasions needing lens protection.

Description

technical field [0001] The invention belongs to the technical field of laser seam sensors for robots, and in particular relates to an anti-splash device and method for laser seam sensors for robot welding torches. Background technique [0002] In the field of welding robots, the laser seam sensor, as an important part, has the function of seam identification and detection, obtains the position information of the seam, and transmits it to the robot to guide the robot to perform accurate welding. However, a large amount of welding slag splash and dust will be generated during the welding process. Long-term welding will cause a large amount of welding slag particles to adhere to the surface of the unprotected front light window protection lens of the sensor and it is difficult to clean up, which will affect the accuracy of weld detection and require frequent manual replacement. The light window protects the lens to ensure the normal operation of the sensor, which is time-consum...

However, a large amount of welding slag splash and dust will be generated during the welding process. Long-term welding will cause a large amount of welding slag particles to adhere to the surface of the unprotected front light window protection lens of the sensor and it is difficult to clean up, which will affect the accuracy of weld detection and require frequent manual replacement. The light window protects the lens to ensure the normal operation of the sensor, which is labor-intensive and expensive

[0003] CN 109702395 A discloses an anti-splash component form of a pneumatic component that executes flipping of the baffle. This structural form requires a large space for flipping the baffle, and when the laser sensor is close to the welding torch, collisions between the baffle and the welding torch are prone to occur, and the baffle Hidden danger of collision with welding workpiece

After long-term welding use, a large number of welding slag particles will stick to the baffle, which needs to be cleaned manually
