[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example 1, by Figure 1 The present invention relates to a high-power laser cutting copper tube anti-perforation and slag removal device, including a mounting plate 1, a cutting mechanism 2 at the bottom of the mounting plate 1, and a fixing mechanism 3 on the cutting mechanism 2.

[0025] Specifically, by Figure 2-4The cutting mechanism 2 includes a U-shaped rod 201 fixed to the bottom of the mounting plate 1. A lifting plate 2011 is movably sleeved on the outer side of the U-shaped rod 201. A cylinder 2012 is fixedly installed between the lifting plate 2011 and the mounting plate 1. A U-shaped plate 2013 is fixedly connected to the bottom of the lifting plate 2011. A laser cutting head 203 is fixedly installed on the bottom of the U-shaped plate 2013. Two sliders 2016, both located above the lifting plate 2011, are symmetrically movably sleeved on the outer side of the U-shaped rod 201. The bottoms of the two sliders 2016 are... A connecting post 206 is fixedly connected. A baffle 1 205 and a baffle 2 2019 are fixedly connected to the bottom ends of the two connecting posts 206, respectively. Both connecting posts 206 pass through and are movably connected to the lifting plate 2011. Springs 2017 are fixedly connected between the two sliders 2016 and the lifting plate 2011. The two springs 2017 are respectively sleeved on the outer sides of the two connecting posts 206. A suction frame 204 and a nozzle 202 are fixedly connected to the sides of the baffles 1 205 and baffle 2 2019 that are close to each other, respectively. The mounting plate 1 has multiple slots 2020. A vacuum pump 2014 is fixedly connected to the bottom of the mounting plate 1. A vacuum pipe 2015 is fixedly connected to the vacuum pump 2014. The end of the vacuum pipe 2015 away from the vacuum pump 2014 is connected to an external nitrogen storage tank. A flexible hose 2018 is fixedly connected between the vacuum pump 2014 and the nozzle 202. A vacuum cleaner 2010 and an exhaust pipe 208 are fixedly connected to the bottom of the mounting plate 1. A connecting pipe 209 is fixedly connected between the vacuum cleaner 2010 and the exhaust pipe 208. A flexible hose 207 is fixedly connected between the exhaust pipe 2010 and the suction frame 204. A filter frame 2021 is provided inside the exhaust pipe 208. A side plate 2024 is provided on the outside of the exhaust pipe 208. An installation groove 2022 is provided on the exhaust pipe 208. A sealing plate 2023 is fixedly connected between the side plate 2024 and the filter frame 2021. The sealing plate 2023 is inserted into the installation groove 2022. A rubber ring 2025 is fixedly connected to the outside of the side plate 2024. The rubber ring 2025 is fitted on the outside of the sealing plate 2023 and fits against the exhaust pipe 208.

[0026] In operation, cylinder 2012 is first activated, causing the lifting plate 2011 to slide downwards along the U-shaped rod 201. This, in turn, causes the laser cutting head 203 to move downwards via the U-shaped plate 2013. Simultaneously, baffles 1 205 and 2 2019 descend. Since baffles 1 205 and 2 2019 are supported by two springs 2017, and both springs are elastic, they maintain elastic contact with the copper tube, preventing overfeeding of the U-shaped plate 2013 and thus preventing laser energy concentration that could cause puncture. When the laser cutting head 203 cuts the copper tube, the vacuum pump 2014 is activated simultaneously to draw nitrogen gas through the vacuum pipe 2015. The nitrogen gas then enters the nozzle 202 through the second hose 2018 and is sprayed out from each strip groove 2020, allowing the nitrogen gas to blow directly onto the cutting point, blowing away the molten slag and cooling the cut, thus inhibiting perforation caused by excessive ablation. Then, the vacuum cleaner 2010 is activated to extract the copper slag through the first hose 207 and the suction frame 204. The copper slag then enters the exhaust pipe 208 through the connecting pipe 209, and finally, the copper slag falls into the filter frame 2021 for collection.

[0027] Specifically, by Figure 5 The fixing mechanism 3 includes a positioning block 301 fixed to the bottom of the side plate 2024, a positioning rod 302 fixedly connected to the outside of the exhaust pipe 208, the positioning block 301 sleeved on the outside of the positioning rod 302, a fixing block 305 fixedly connected to the exhaust pipe 208, a guide rod 304 fixedly connected between the fixing block 305 and the exhaust pipe 208, a threaded sleeve 303 movably sleeved on the outside of the guide rod 304, a limiting cylinder 309 fixedly connected to the side of the threaded sleeve 303 near the positioning block 301, the limiting cylinder 309 sleeved on the outside of the positioning rod 302 and abutting against the positioning block 301, a screw 308 rotatably connected to the outside of the exhaust pipe 208, the threaded sleeve 303 threadedly sleeved on the outside of the screw 308, a drive shaft 307 fixedly connected to one end of the screw 308, and a handwheel 306 fixedly connected to the end of the drive shaft 307 away from the screw 308 passing through the fixing block 305.

[0028] In use, first place the filter frame 2021 inside the exhaust pipe 208 so that the positioning block 301 is fitted on the outside of the positioning rod 302. Then rotate the handwheel 306, which drives the screw 308 to rotate through the drive shaft 307 and drives the screw sleeve 303 to slide along the guide rod 304. At the same time, the limiting cylinder 309 moves horizontally and fits on the outside of the positioning rod 302 until the limiting cylinder 309 abuts against the positioning block 301 to limit the positioning block 301. Finally, the filter frame 2021 is fixed.
