Description

Technical Field

[0001] The present invention relates to a floating breakwater, and particularly to a classification marking device and a marking method for welding defects of marine T-sections. Background Art

[0002] Marine T-sections are widely used in ship structures. Due to the relatively complex welding process, welding defects such as incomplete welding, porosity, undercut, and weld bead often occur at the welding joints of T-sections. Investigations have found that currently, most shipbuilding enterprises detect and mark welding defects of T-sections based on manual visual inspection and manual scribing, in order to facilitate subsequent defect repair. There are significant defects such as large recognition errors, low efficiency, and high labor requirements. With the development of modern intelligent technologies, new technologies such as image recognition have been applied to welding defect detection, greatly improving the accuracy and efficiency of defect detection. However, there is currently a lack of technical means and devices for reliably marking welding defects. In order to achieve the automation and intelligence of welding defect detection and marking of T-sections and contribute to the digital development trend of shipbuilding, there is an urgent need for a classification marking device for welding defects of marine T-sections.

The chalk is installed on the chalk clamping device; the chalk clamping device is nested in the chalk guiding device and connected together by an elastic element to ensure that there is no mutual extrusion between the marking device and the T-shaped section.

[0012] The elastic element is a spring. The chalk is pressed against the surface of the T-shaped section through the elastic element, and reliable marking can also be achieved when encountering surface depressions or protrusions.

[0013] 10. A classification marking method for welding defects of marine T-shaped sections, comprising the following steps:

[0014] S1: Through visual recognition technology, the welding area of the marine T-shaped section is detected to identify the position and type of welding defects. Different marking notations are assigned to different types of defects.

[0015] S2: The motion controller generates control instructions according to the identified position and type of welding defects.

[0016] S3: According to the control instructions, the lifting device drives the marking device to move downward, so that the end of the chalk in the marking device presses on the surface of the T-shaped section. As the welding equipment moves, a line is drawn on the surface of the T-shaped section.

[0017] S4: While the chalk follows the movement of the welding equipment, the translation device can drive the marking device to move left and right, so as to draw different marking notations corresponding to the allocated welding defects on the surface of the T-shaped section, so as to realize the classification marking of welding defects for subsequent defect repair.
