[0016] Working principle: When in use, the scalpel needs to be placed on the placement table 10. The telescopic column 12 and the lifting rod 13 in contact with the scalpel are forced to descend. The number, position and descending height of the lifting rod 13 are confirmed by the height sensing device 15, so as to judge the specific position of the scalpel on the placement table 10 and the size of the scalpel. The position of the scalpel is adjusted according to these data to align it with the center position of the processing groove. The push rod motor 5 is used to control the lifting frame 6 to move up and down to adjust the height. The first moving component 7 is used to control the moving frame 8 to move and change the position. After the adjustment is completed, the second moving component 9 is opened to control the placement table 10 moves with the scalpel so that its end enters the rotating cover 21 of the welding assembly 3. At the same time, the support table 17 uses the second spring 16 to support the placement table 10 to prevent it from deformation. When the end of the scalpel enters the rotating cover 21, it will first be detected by the infrared detection device 40. After the cutter head completely enters the rotating cover 21, the range detected by the infrared detection device 40 at the connection between the cutter head and the handle will increase, thereby confirming the required welding position. Then, the rotating motor 32 is turned on to control the rotation of the laser emitter 31, adjust the angle, and adjust the focal length by moving the scalpel to start welding. During welding, the suction and pressure device 37 extracts the gas in the central chamber 34 and the dispersion chamber 36, creating a vacuum and generating suction to suck out the welding smoke generated by welding in the rotating cover 21. At the same time, the driving motor 26 controls the rotation of the rotating cover 21 and the rotating frame 23 through the first gear 27, the second gear 28 and the third gear 29, so that the internal laser emitter 31 rotates with the welding part as the center of the circle to perform all-round welding. When the waste discharge trough 33 rotates to connect with the contact frame 38, the welding slag falls into the collection box 39 due to gravity for storage and is awaiting subsequent cleaning.
