Bellows primarily include metal bellows, bellows expansion joints, bellows heat exchange tubes, diaphragm capsules, and metal hoses. Cutting these various types of bellows generates debris. To ensure the quality of the finished product and prevent interference from flying debris during processing, timely cleaning of these contaminants, primarily in the form of flying chips (laser cutting produces slag), is essential.

[0030] refer to Figure 4 As shown, a method for removing cutting contaminants during pipe cutting is implemented by the cutting control module 500 and the decontamination adsorption control module 600, and includes: Obtain the cutting position of the bellows and control the movement of the horizontal cantilever so that the adsorption port of the decontamination adsorption tube moves to the cutting position. In this step, the cutting position of the bellows is obtained as an action reference, and the adsorption port of the decontamination adsorption tube is moved to the cutting position to facilitate the synchronization of subsequent cutting and adsorption actions. The second servo motor is driven to rotate at a speed that is the same as the speed of the laser cutter. In this step, the rotation of the second servo motor is controlled to synchronize the rotation of the bellows and the rotation of the suction port, thereby allowing the suction port to be accurately aligned with the cutting position in real time to ensure that the slag and flying chips generated by the cutting fall into the suction port. The negative pressure machine is driven to generate adsorption. In this step, the pneumatic negative pressure machine generates adsorption, thereby sucking away the slag and flying chips generated in real time during cutting.
