Visual welding robot with dynamic light supplementing effect and dynamic adjusting method

Abstract

The invention discloses a visual welding robot with a dynamic light supplementing effect and a dynamic adjusting method and belongs to the technical field of welding robots. The irradiation angle of a light supplementing lamp of an existing traditional welding robot is consistent, if the direction of a welding head is changed, manual adjustment is needed, operation is tedious; and during use, a supporting platform is large in size, as a result, the storage and the carrying of the robot are inconvenient. The invention just aims to solve the above problems. According to the visual welding robot with the dynamic light supplementing effect and the dynamic adjusting method, a base and a supporting frame are arranged; one side of a welding arm is provided with a light compensating mechanism, and the front end of the light compensating mechanism is provided with a dynamic adjustment mechanism; and multiple sets of light supplementing lamp beads are focused at one position, a shifting rod is manually shifted, an inner gear ring can rotate automatically, the position of the end, close to the inner gear ring, of a linkage rod is not changed, the linkage rod is pulled by a bending rod, the linkage rod and the inner gear ring are in a perpendicular state, a concave lens is located at the right front end of the light supplementing lamp beads, light beams irradiated by the light supplementing lamp beads penetrate through the concave lens, in other words, focus points of the multiple sets of light supplementing lamp beads are changed, and the distance of the focus points is conveniently changed.

Description

technical field [0001] The invention relates to the technical field of welding robots, in particular to a visual welding robot with a dynamic supplementary light effect and a dynamic adjustment method. Background technique [0002] Welding robots are industrial robots engaged in welding (including cutting and spraying). According to the definition of the International Organization for Standardization that an industrial robot belongs to a standard welding robot, an industrial robot is a multipurpose, reprogrammable, automatic control manipulator with three or more programmable axes, used in the field of industrial automation. In order to adapt to different purposes, the mechanical interface of the last axis of the robot is usually a connecting flange, which can be connected to different tools or end effectors. The welding robot is equipped with a welding tongs or a welding (cutting) torch on the flange of the final axis of the industrial robot, so that it can perform welding...

Problems solved by technology

[0003] Application number CN202110822057.X is a fully automatic visual spot welding robot, including a multi-degree-of-freedom robot welding arm and a multi-degree-of-freedom material platform corresponding to the robot welding arm. The robot welding arm includes a rotating base 1, and the rotating base One is connected with a rotatable robot arm through a driving motor, the robot arm is connected with a rotatable robot forearm through a drive motor two, and the robot forearm is connected with a rotatable wrist arm through a drive motor three, An automatic welding gun is installed on the wrist arm, and the welding wire of the automatic welding gun is connected with the wire feeding device arranged on the arm of the robot. The automatic welding gun is provided with a CCD camera device corresponding to the gun head of the automatic welding gun, and an automatic The gun head of the welding torch and the cage fume cover corresponding to the CCD camera device, the cage fume cover communicates with the flue gas discharge treatment box arranged on the robot arm through a flexible connecting pipe, and the buzzer alarm is arranged on the robot arm , the material platform includes a rotating base 2, and the rotating base 2 is connected with a rotatable support arm through a drive motor 4, and the support arm is connected with a rotatable support platform through a drive motor 5, and the support platform is provided with Adjustable material pressure plate, the first rotating base, the second rotating base, the first driving motor, the second driving motor, the third driving motor, the fourth driving motor, the fifth driving motor, the wire feeding device, the automatic welding torch, the CCD camera device, and the buzzer alarm The device, cage and smoke cover are electrically connected to the external controller. Although this patent can supplement the light on the welding head, the angle of light irradiation is the same. If the direction of the welding head changes, manual adjustment is required, and the operation is more cumbersome. And when in use, the size of the supporting platform is relatively large, which is not convenient for storage and handling, and the use effect is not ideal
