Problems solved by technology

[0003] However, the existing underwater welding robots cannot automatically find the weld on the workpiece to be welded, and people need to perform remote control on the water surface. Specifically, the underwater welding robot sends the underwater image wirelessly to the water computer system for display to the operator. The operator controls the welding parts of the underwater robot to the welding position according to the displayed results to complete the welding operation
This underwater welding method needs to constantly interact with water equipment and personnel, which wastes manpower and material resources, and the level of automation is not high

Embodiment Construction

[0014] The embodiments of the image recognition-based underwater welding robot of the present invention will be described in detail below with reference to the accompanying drawings.

[0015] With the start of a large number of bridge infrastructure projects and the development of the offshore oil and gas industry, there are more and more cases of underwater operations. Due to the particularity of the underwater environment, operators can no longer perform welding operations as normal as on land. , and can only use welding tools to replace their own underwater welding. Among them, the most commonly used equipment is underwater welding robots.

[0016] The underwater welding robot in the prior art has a welding torch drive mechanism and a workpiece image acquisition mechanism, which can send the real-time working conditions of the welding workpiece to the control equipment on the water surface for the operator's reference, and the operator can also drive the welding torch in rea...

Abstract

The invention relates to an underwater welding method. The underwater welding method includes the following steps: (1) providing an underwater welding robot based on image identification, wherein the underwater welding robot comprises a welding gun driving device, a high-definition image sensor, an image processor and a master controller; the high-definition image sensor is used for collecting welding images of welding workpieces; the image processor is connected with the high-definition image sensor and executes image identification processing on the welding images so as to detect welding line positions in the welding images; the master controller is connected with the welding gun driving device and the image processor, and the welding gun driving device is controlled based on the welding line positions to drive an underwater welding gun to reach the welding line positions; (2) the underwater welding robot is used for welding.

Description

technical field [0001] The invention relates to the field of underwater robots, in particular to an underwater welding method. Background technique [0002] Robot, the English name is Robot, is the abbreviation of automatic control machine. In contemporary industry, a robot refers to a man-made mechanical device that can perform tasks automatically, and is used to replace or assist human work, especially in some places that are dangerous and harmful to the human body or the human body cannot stay for a long time, such as EOD robots, underwater robots, etc. Underwater welding is an important application of underwater robots. Using underwater robots to perform underwater welding solves the problem that people cannot stay underwater for a long time to perform welding. [0003] However, the existing underwater welding robot cannot automatically find the welding seam on the workpiece to be welded, and people need to perform remote control on the water surface. Specifically, the...
