Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0047] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense.

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0048] Refer to the following Figures 1 to 9 The present invention describes a processing robot according to some embodiments of the present application.

[0049] See also Figures 1 to 9 As shown, an embodiment of the first aspect of the present application provides a processing robot for cylinder processing, which includes a crawling component, a processing component, a transmission component and a detection component, wherein the crawling component is provided with an adsorption portion, which can apply an adsorption force to the cylinder so that the crawling component can crawl on the surface of the hull cylinder. The processing component is provided on the crawling component for processing the workpiece to be processed.

[0061] Optionally, both the first rolling portion 11 and the second rolling portion 12 may be tracks, so as to increase the contact area between the first rolling portion 11 and the second rolling portion 12 and the cylinder, thereby improving the stability of the processing robot.

[0062] Preferably, if Figure 2As shown, the above-mentioned crawler belt is formed by a plurality of chain blocks connected end to end in sequence, and each chain block can be provided with the above-mentioned second adsorption member 22 to ensure that each chain block can fit the cylinder.

[0063] Optionally, the first adsorption member 21 and the second adsorption member 22 may both be permanent magnets. However, the present invention is not limited thereto, and the first adsorption member 21 and the second adsorption member 22 may also be electromagnets or other devices having an adsorption function.

[0064] Correspondingly, the above-mentioned cylinder can be a magnetic metal cylinder, for example, an iron cylinder, a nickel cylinder, a cobalt cylinder, etc.

[0067] Preferably, if Figure 1 As shown, the above-mentioned detection component may include a position sensing part 31, and the position sensing part 31 may be provided at both ends of the chassis 10 in the moving direction of the crawling component, so as to ensure that the detection component can obtain the road condition information at the front end of the moving direction during the bidirectional movement (i.e. forward and backward) of the processing robot along the second direction F2, and then confirm the position information of the processing robot.

[0068] Optionally, the position sensor 31 may be a laser tracking sensor to collect information about the margin line, weld seam, and marking line. However, the position sensor is not limited thereto and may also be a CCD camera or other visual sensor as long as it enables the detection component to obtain road condition information at the front end of the moving direction.
