[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The sliding rod slides inside the linkage slot, thereby driving the sliding member to move horizontally, thereby driving the sponge block to rotate in contact with the top of the mounting plate. At the same time, the cleaning liquid inside the liquid storage tank soaks the sponge block, thereby cleaning the top of the protective mirror. The wiping member then wipes the water stains on the top of the mounting plate. Compared with simple wiping with a cloth or blowing, this structure has a better cleaning effect. It can not only clean the dirt on the top of the protective mirror, but also maintain the top mirror surface of the protective mirror and reduce scratches. 2. The horizontal movement of the sliding member drives the second slide bar to move horizontally, so that the second slide bar slides along the track. When the blade moves to the bottom of the protective mirror, the blade will fit the bottom of the protective mirror to scrape off the welding slag adhered to the bottom of the mirror and collect it into the collection box. In this way, the welding slag adhered to the bottom of the protective mirror during the welding process is scraped off and collected, thereby preventing the welding slag from interfering with the light transmittance of the protective mirror and affecting the laser cutting and welding effect. 3. The motor drives the threaded rod to rotate, so that the movable plate moves up and down along the square vertical groove of the panel. The movable plate drives the limit frame to move up and down as a whole through a fixed connection with the limit frame. At the same time, the opening and closing angle of the baffle is adjusted through the linkage to achieve precise adjustment of the focal length between the protective mirror and the lens, thereby adjusting the light penetration imaging of the lens and the protective mirror to adapt to different positioning requirements. When the movable plate drives the limit frame to move vertically, it will drive the sliding plate to move vertically synchronously. When the limit frame rises to the highest point, the baffle opens and closes at the maximum angle, which makes it easier for the staff to observe the status of the cutting head nozzle. When the limit frame drops to the bottom, the welding slag adhered to the cutting head nozzle during the welding process will be scraped off, so as to avoid the welding slag adhering to the bottom of the carrier nozzle, thereby causing unstable welds or causing uneven cut surfaces during laser cutting, thereby increasing the subsequent processes.

The bottom of the liquid outlet pipe 224 is fixedly connected and communicated with the liquid blocking plate 230. The liquid blocking plate 230 is funnel-shaped, so that when the liquid outlet pipe 224 rotates, the cleaning liquid is evenly sprinkled on the sponge block. 231 surface, a circular hole three is opened on the side wall of the sponge block 231, and the rotating shaft 1 219 is fixedly penetrated by the circular hole three, so that the rotating shaft 1 219 drives the sponge block 231 to rotate, the wiping member 232 is fixedly connected to the side wall of the sliding member 214, and the bottom of the wiping member 232 is fitted with the top of the mounting plate 28. The side wall of the wiping member 232 is fixed to the cleaning cloth by bolts, the fixing plate 233 is fixedly connected to the bottom of the connecting block 216, and the guide plate 234 is fixedly connected to the side wall of the fixing plate 233. There is a gap of 3 to 5 mm between the top of the guide plate 234 and the bottom of the sliding member 214, so as to avoid the interference of the guide plate 234 with the horizontal movement of the sliding member 214.

[0043] When the rotating shaft 219 rotates, it will also drive the sponge block 231 to rotate, thereby driving the sponge block 231 to rotate in contact with the top of the carrying plate 28, so that with the assistance of the cleaning liquid soaked in the sponge block 231, the sponge block 231 cleans the top of the carrying plate 28 and the top of the protective mirror 210, and the wiping member 232 will move synchronously driven by the sliding member 214, so that the wiping member 232 drives the cleaning cloth to wipe the cleaning liquid remaining on the top of the carrying plate 28 and the top of the protective mirror 210, thereby completing the cleaning of the mirror surface on the top of the protective mirror 210.

When the slide bar 236 moves to the bottom of the protective mirror 210, it will move upward so that the blade 243 fits the bottom of the protective mirror 210. The slide bar 236 moves through the inner wall of the track 235. The end of the slide bar 236 is fixedly connected to the outer wall of the slider 1 237.

The two ends of the installation box 240 are fixedly connected to the bottom of the linkage frame 239. The top of the installation box 240 is plugged into the outer wall of the collection box 241 and the inner wall of the installation box 240. Two inclined plates are fixedly connected to the top of the collection box 241. The inclined plates increase the collection area of the fallen welding slag. The connector 242 is fixedly connected to the end of the slide bar 236 away from the slider 237. The blade 243 is fixed through the top of the connector 242 by bolts. The connector 242 has two 30° inclined blades 243 symmetrically arranged at the center, so that when the sliding member 214 moves horizontally in the forward and reverse directions, the welding slag on the bottom surface of the protective mirror 210 can be cleared.

[0045] The horizontal movement of the sliding member 214 will also drive the linkage frame 239 to move horizontally, and the linkage frame 239 will drive the limit member 238 to move synchronously. At this time, the slide bar 236 will slide in the track 235, so that the slide bar 236 drives the slider 1 237 to move vertically. As the track of the track 235 is guided, the slide bar 236 will drive the blade 243 to fit the bottom of the protective mirror 210 when it is about to move to the bottom of the protective mirror 210, thereby scraping off the welding slag adhered to the bottom of the protective mirror 210. After scraping, the welding slag will fall into the collection box 241. When the welding and cutting are completed, you only need to take out the collection box 241 and clean up the welding slag in the collection box 241.

The speed at which the laser is irradiated on the top of the carrying plate 28 and then reflected is used to detect the height of the carrying plate 28 in real time. The laser sensor is interconnected with the control unit signal. A photoelectric sensor (not shown in the figure) is installed on the top of the cutting head 13. The beam range and beam intensity of the protective mirror 210 are measured. The degree of dirt residue on the surface of the protective mirror 210 is detected, and then the feedback is sent to the control unit to further trigger the cleaning / scraping action. The stroke of the limit frame 27 is 50mm. The sponge block 231 is made of PU foam with a pore size of 0.8-1.2mm. The cleaning liquid is a neutral surfactant aqueous solution.
