[0033] Example 1 Reference Figures 1 to 7 , which is the first embodiment of the present invention, provides a method for using a laser cutting device for metal processing. Through the method for using the laser cutting device for metal processing, harmful gases can be filtered, and the laser head 105 can be cleaned and protected.

[0034] The exhaust fan 208 inside the gas filter mechanism 200 sucks harmful exhaust gas into the air box 201, so that the activated carbon filter plate 204 inside the air box 201 can filter the harmful exhaust gas; With the exhaust fan 208 started, the protection component 305 and the rotating cleaning component 306 can be driven to clean the laser head 105 before use, and the protection component 305 can be pushed to protect the laser head 105 when it is not in use.

[0035] After the exhaust fan 208 inside the gas filter mechanism 200 is started, harmful exhaust gas can be sucked into the air box 201, so that the harmful exhaust gas can be filtered by the activated carbon filter plate 204 after entering the air box 201, and the filtered gas can be used to clean the surface of the slide rail frame 102 for a second time through the air blowing cleaning component 212, and the laser head 105 can be cooled at the same time; The push protection component 305 inside the protection and cleaning mechanism 300 can move as the exhaust fan 208 is started, so that the push protection component 305 can drive the rotating cleaning component 306 to perform protection and cleaning before and after use, and the rotating cleaning component 306 can be sprayed with anhydrous alcohol through the spraying component 303 to increase the cleaning effect of the rotating cleaning component 306 on the laser head 105.

[0036] Example 2 Reference Figures 1 to 5 , which is the second embodiment of the present invention, provides a gas filtering mechanism 200, through which harmful exhaust gas can be filtered and reused.

[0037] The gas filtering mechanism 200 includes an air box 201, which is fixedly connected to the front of the laser controller 104.

The connecting pipe 206 is fixedly connected to the left side of the bottom of the laser controller 104. 06 The end away from the connecting cover 205 is fixedly connected to the sealed box 207, an exhaust fan 208 is fixedly installed on the left side inside the sealed box 207, a vibration cleaning component 209 is movably connected to the top of the fixed frame 203, a collecting component 210 is provided at the bottom of the left side of the air box 201, exhaust holes 211 are provided on the right sides of the front and back of the sealed box 207, the top and bottom of the right side of the back of the sealed box 207 are fixedly connected to the blowing cleaning component 212, and the right side of the front of the sealed box 207 is fixedly connected to the heat dissipation component 213.

[0038] The vibration cleaning assembly 209 includes a rotating cam 209a, the top of which is fixedly connected to a transmission rod 209b, the top of which passes through the top of the air box 201 and is movably connected to the air box 201, a tooth plate 209c is provided on the top of the laser controller 104, the back of the tooth plate 209c is fixedly connected to the front of the slider 103, the top of the transmission rod 209b is fixedly connected to a transmission gear 209d, the transmission gear 209d is meshed with the tooth plate 209c, the top and bottom of the inner wall of the fixed frame 203 are fixedly connected to a connecting plate 309e, the right side of the connecting plate 309e is fixedly connected to a tension spring 209f, and the right end of the tension spring 209f is fixedly connected to the left side of the activated carbon filter plate 204.

[0039] The collecting assembly 210 includes a taking groove 210a, which is opened at the bottom of the left side of the air box 201. The interior of the taking groove 210a is movably connected to a sealed collecting box 210b. The left side of the bottom of the air box 201 is fixedly connected to an inclined plate 210c, and the inclined plate 210c is movably connected to the sealed collecting box 210b.

[0040] The air blowing cleaning assembly 212 includes a ventilation pipe 212a, which is connected to the exhaust hole 211 on the back of the sealing box 207. Mounting pipes 212b are fixedly installed on both sides of the laser control. The back of the mounting pipe 212b is fixedly connected to a nozzle 212c. There are several nozzles 212c distributed at equal distances. The ventilation pipe 212a is connected to the mounting pipe 212b.

[0041] The heat dissipation assembly 213 includes a fixed tube 213a, which is fixedly installed on the right side of the front of the sealing box 207 and is connected to the exhaust hole 211. An air outlet ring tube 213b is provided at the bottom of the laser controller 104. A connecting rod 213c is fixedly connected to the top of the air outlet ring tube 213b. The top of the connecting rod 213c is fixedly connected to the bottom of the laser controller 104, and the fixed tube 213a is connected to the air outlet ring tube 213b.

[0042] Specifically, when the transmission gear 209d moves on the tooth plate 209c, the rotating cam 209a will be driven to rotate through the transmission rod 209b, and the tension spring 209f on the connecting plate 309e will drive the activated carbon filter plate 204 to fit with the rotating cam 209a through its own tension, so that the rotating cam 209a can drive the activated carbon filter plate 204 to vibrate after rotating, so that the impurities on the activated carbon filter plate 204 can fall downward, and the impurities falling downward will be collected by the sealed collection box 210b inside the taking groove 210a. At the same time, the inclined plate 210c can prevent the impurities falling downward from falling through the suction pipe 202.

[0043] The filtered gas will enter the interior of the ventilation pipe 212a and the fixed pipe 213a through the exhaust hole 211, so that the gas entering the ventilation pipe 212a can be blown to the surface of the slide frame 102 through the nozzle 212c on the mounting pipe 212b, thereby cleaning the surface of the slide frame 102 and ensuring the stability of the laser controller 104 moving on the slide frame 102. The gas entering the fixed pipe 213a will be blown to the laser head 105 through the air outlet ring pipe 213b to dissipate the heat of the laser head 105 and prevent the laser head 105 from being in a high temperature state for a long time.

[0044] Furthermore, before the laser head 105 performs laser cutting, the exhaust fan 208 inside the sealed box 207 is started, so that after the exhaust fan 208 is started, the air inside the sealed box 207 will be blown to one side, so that the inside of the sealed box 207 is in a negative pressure state, and the outside air will enter the air box 201 through the intake pipe 202, so that the outside air passes through the activated carbon filter plate 204 inside the fixed frame 203, so that the activated carbon filter plate 204 can filter the outside air, and the air filtered by the activated carbon filter plate 204 will enter the sealed interior through the connecting cover 205 and the connecting pipe 206, so that the harmful exhaust gas generated by the laser head 105 during laser cutting will be sucked into the air box 201 and filtered by the activated carbon filter plate 204.

[0045] When the laser controller 104 moves on the slide rail frame 102, it will drive the air box 201 to move. As the air box 201 moves, the transmission gear 209d will be driven to rotate and move on the tooth plate 209c through the transmission rod 209b. As the transmission gear 209d rotates, the rotating cam 209a can be driven to rotate through the transmission rod 209b, and the activated carbon filter plate 204 will be subjected to the tension of the tension spring 209f on the connecting plate 309e and fit with the rotating cam 209a, so that the rotating cam 209a can drive the activated carbon filter plate 204 to vibrate after rotation, so that the impurities on the activated carbon filter plate 204 can fall downward after being vibrated, and the fallen impurities will be collected by the sealed collection box 210b inside the taking groove 210a. At the same time, the inclined plate 210c can prevent the impurities from falling downward into the interior of the suction pipe 202. The user can take out the sealed collection box 210b after long-term use to clean the impurities.

[0046] As the exhaust fan 208 is started, the gas will be blown to one side, so that the sealing plate 304 will move to the right as the gas is blown. When the sealing plate 304 moves to the right inside the sealing box 207 and leaks out the exhaust hole 211, the gas will be discharged through the exhaust hole 211, and the sealing plate 304 will maintain the position of the exhaust hole 211 inside the sealing box 207. When the exhaust hole 211 leaks, the gas inside the sealing box 207 will enter the ventilation pipe 212a and the fixed pipe 213a.

[0047] After the gas enters the ventilation pipe 212a, it will be injected into the mounting pipe 212b and ejected through the nozzle 212c on the mounting pipe 212b, so that the gas ejected from the nozzle 212c can clean the surface of the slide rail frame 102. After the gas enters the fixing pipe 213a, it will be injected into the air outlet ring pipe 213b fixed by the connecting rod 213c, so that the gas is ejected through the air outlet ring pipe 213b, so that the ejected gas can dissipate heat for the laser head 105.

[0048] Example 3 Reference Figures 1 to 6 , which is the third embodiment of the present invention, provides a protective cleaning mechanism 300, through which the laser head 105 can be cleaned and protected before and after use.

[0049] The protective cleaning mechanism 300 includes a mounting frame 301, which is fixedly connected to the bottom of the laser controller 104.

[0051] The push protection assembly 305 includes a fixed rod 305a, a movable plate 305b is fixedly connected to the right side of the fixed rod 305a, a protective plate 305c is fixedly connected to the right side of the movable plate 305b, the protective plate 305c is located at the bottom of the laser head 105, a guide block 305d is fixedly connected to the front side of the top of the protective plate 305c, the guide block 305d is movably connected to the extrusion disk 303e, a spring 305e is fixedly connected to the right side of the sealing plate 304, the right end of the spring 305e is fixedly connected to the right side of the inner wall of the sealing box 207, and the movable plate 305b is movably connected to the mounting bracket 301.

[0052] The rotating cleaning assembly 306 includes a tooth groove 306a, which is opened on the rear side of the inner wall of the mounting frame 301, and a movable groove 306b is opened at the bottom of the movable plate 305b. The bottom of the movable plate 305b is fixedly connected to a support frame 306c, and the rear side of the top of the support frame 306c is movably connected to a rotating gear 306d, and the rotating gear 306d is meshed with the tooth groove 306a. The top of the support frame 306c is movably connected to a driven gear 306e, and the driven gear 306e is meshed with the rotating gear 306d. The top of the driven gear 306e is fixedly connected to a cleaning cloth 306f, and the cleaning cloth 306f is movably connected to the laser head 105.

[0053] Specifically, when the sealing plate 304 moves, it will drive the movable plate 305b to move through the fixed rod 305a, so that the movable plate 305b can drive the protective plate 305c to move inside the mounting frame 301, so that the moved movable plate 305b and the protective plate 305c can be away from the laser head 105, avoiding the movable plate 305b and the protective plate 305c from interfering with the normal use of the laser head 105.

[0054] During the movement of the protective plate 305c, the supporting frame 306c drives the rotating gear 306d to engage with the tooth groove 306a, so that the rotating gear 306d can drive the driven gear 306e to rotate, and after the driven gear 306e rotates, it can drive the cleaning cloth 306f to rotate, so that the rotating cleaning cloth 306f can clean the laser head 105.

[0055] During the movement of the protective plate 305c, the extrusion plate 303e can be squeezed through the guide block 305d, so that the extrusion plate 303e can squeeze the telescopic hose 303d, so that the anhydrous alcohol inside the telescopic hose 303d can be squeezed and sprayed on the cleaning cloth 306f through the spray head 303h, so that the anhydrous alcohol can clean and sterilize the cleaning cloth 306f while increasing the cleaning effect of the cleaning cloth 306f on the laser head 105.

[0056] Furthermore, when the sealing plate 304 moves, the spring 305e is compressed and the moving plate 305b is driven to move inside the mounting frame 301 through the fixing rod 305a, so that the fixing rod 305a drives the moving plate 305b to move inside the mounting frame 301. When the moving plate 305b moves inside the mounting frame 301, it drives the protective plate 305c to move to the right, so that the protective plate 305c originally located at the bottom of the laser head 105 moves to the right, and the protective plate 305c drives the rotating gear 306d to rotate through the supporting frame 306c. When the rotating gear 306d moves inside the mounting frame 301, it meshes with the tooth groove 306a and rotates, so that the rotating gear 306d can drive the driven gear 306e inside the movable groove 306b to rotate, and the driven gear 306e can drive the cleaning cloth 306f to rotate after the rotation. When the moving plate 305b drives the rotating cleaning cloth 306f to move to the bottom of the laser head 105, the rotating cleaning cloth 306f can clean the lens of the laser head 105, thereby cleaning the laser head 105 before use.

[0057] The anhydrous alcohol in the liquid storage tank 302 is injected into the telescopic hose 303d through the connecting pipe 303a and the one-way valve 303b. When the protective plate 305c moves to the right, the guide block 305d is driven to move to the right. As the guide block 305d moves, it contacts the squeezing plate 303e and pushes the squeezing plate 303e upward, so that the squeezing plate 303e can squeeze the telescopic hose 303d, so that the anhydrous alcohol in the telescopic hose 303d is injected into the water pipe 303f and flows through the water pipe 303f. The cleaning cloth 306f is sprayed through the spray head 303h on the connecting frame 303g. At this time, the cleaning cloth 306f enters the spraying range of the spray head 303h and is separated from the laser head 105, so that the anhydrous alcohol is sprayed onto the cleaning cloth 306f to sterilize the cleaning cloth 306f, and as the protective plate 305c moves, the guide block 305d will be separated from the extrusion disk 303e, so that the anhydrous alcohol inside the liquid storage tank 302 will be injected into the telescopic hose 303d again through the connecting pipe 303a and the one-way valve 303b.

[0058] When the laser head 105 completes laser cutting and the exhaust fan 208 is closed, the compressed spring 305e will drive the sealing plate 304 to move to the left for reset through its own elastic force, so that the sealing plate 304 will drive the movable plate 305b and the protective plate 305c to move to the left for reset through the fixed rod 305a. In the process of the protective plate 305c moving to the left for reset, the guide block 305d will contact the extrusion disk 303e again and squeeze the telescopic hose 303d through the extrusion disk 303e, so that after the telescopic hose 303d is squeezed, the anhydrous alcohol inside will be injected into the water pipe 303f and sprayed onto the cleaning cloth 306f through the spray head 303h on the connecting frame 303g, and the movable protective plate 305c will drive the rotating gear 306d to move through the supporting frame 306c. When the rotating gear When the wheel 306d moves inside the mounting frame 301, it meshes with the tooth groove 306a and rotates, so that the rotating gear 306d can drive the driven gear 306e inside the movable groove 306b to rotate, and the driven gear 306e can drive the cleaning cloth 306f to rotate after rotating, so that when the movable plate 305b drives the rotating cleaning cloth 306f to move to the bottom of the laser head 105, the rotating cleaning cloth 306f can clean the lens of the laser head 105, and the cleaning cloth 306f sprayed with anhydrous alcohol can increase the cleaning effect of the laser head 105, thereby completing the cleaning of the laser head 105 after use, and after the movable plate 305b and the protective plate 305c are completely reset, the protective plate 305c is located at the bottom of the laser head 105, so that the protective plate 305c can protect the laser head 105 when it is not in use.

[0059] The remaining structure is the same as that of Example 2.

[0060] Example 4 Reference Figures 1 to 7 , which is the fourth embodiment of the present invention, is different from the third embodiment in that: a laser cutting device for hardware processing.

[0061] Before the laser head 105 performs laser cutting, the exhaust fan 208 inside the sealed box 207 is started. After the exhaust fan 208 is started, the air inside the sealed box 207 will be blown to one side, so that the inside of the sealed box 207 is in a negative pressure state, and the outside air will enter the air box 201 through the suction pipe 202, so that the outside air passes through the activated carbon filter plate 204 inside the fixed frame 203, so that the activated carbon filter plate 204 can filter the outside air, and the air filtered by the activated carbon filter plate 204 will enter the sealed interior through the connecting cover 205 and the connecting pipe 206, so that the harmful exhaust gas generated by the laser head 105 during laser cutting will be sucked into the air box 201 and filtered by the activated carbon filter plate 204.

[0062] When the laser controller 104 moves on the slide rail frame 102, it will drive the air box 201 to move. As the air box 201 moves, the transmission gear 209d will be driven to rotate and move on the tooth plate 209c through the transmission rod 209b. As the transmission gear 209d rotates, the rotating cam 209a can be driven to rotate through the transmission rod 209b, and the activated carbon filter plate 204 will be subjected to the tension of the tension spring 209f on the connecting plate 309e and fit with the rotating cam 209a, so that the rotating cam 209a can drive the activated carbon filter plate 204 to vibrate after rotation, so that the impurities on the activated carbon filter plate 204 can fall downward after being vibrated, and the fallen impurities will be collected by the sealed collection box 210b inside the taking groove 210a. At the same time, the inclined plate 210c can prevent the impurities from falling downward into the interior of the suction pipe 202. The user can take out the sealed collection box 210b after long-term use to clean the impurities.

[0063] As the exhaust fan 208 is started, the gas will be blown to one side, so that the sealing plate 304 will move to the right as the gas is blown. When the sealing plate 304 moves to the right inside the sealing box 207 and leaks out the exhaust hole 211, the gas will be discharged through the exhaust hole 211, and the sealing plate 304 will maintain the position of the exhaust hole 211 inside the sealing box 207. When the exhaust hole 211 leaks, the gas inside the sealing box 207 will enter the ventilation pipe 212a and the fixed pipe 213a.

[0064] After the gas enters the ventilation pipe 212a, it will be injected into the mounting pipe 212b and ejected through the nozzle 212c on the mounting pipe 212b, so that the gas ejected from the nozzle 212c can clean the surface of the slide rail frame 102. After the gas enters the fixing pipe 213a, it will be injected into the air outlet ring pipe 213b fixed by the connecting rod 213c, so that the gas is ejected through the air outlet ring pipe 213b, so that the ejected gas can dissipate heat for the laser head 105.

[0065] When the sealing plate 304 moves, the spring 305e is compressed and the moving plate 305b is driven to move inside the mounting frame 301 through the fixing rod 305a, so that the fixing rod 305a drives the moving plate 305b to move inside the mounting frame 301. When the moving plate 305b moves inside the mounting frame 301, it drives the protective plate 305c to move to the right, so that the protective plate 305c originally located at the bottom of the laser head 105 moves to the right, and the protective plate 305c drives the rotating gear 306d to move through the supporting frame 306c. When the rotating gear 306d moves inside the mounting frame 301, it will mesh with the tooth groove 306a and rotate, so that the rotating gear 306d can drive the driven gear 306e inside the movable groove 306b to rotate, and the driven gear 306e can drive the cleaning cloth 306f to rotate after rotating, so that when the movable plate 305b drives the rotating cleaning cloth 306f to move to the bottom of the laser head 105, the rotating cleaning cloth 306f can clean the lens of the laser head 105, thereby cleaning the laser head 105 before use.

[0066] The anhydrous alcohol in the liquid storage tank 302 is injected into the telescopic hose 303d through the connecting pipe 303a and the one-way valve 303b. When the protective plate 305c moves to the right, the guide block 305d is driven to move to the right. As the guide block 305d moves, it contacts the squeezing plate 303e and pushes the squeezing plate 303e upward, so that the squeezing plate 303e can squeeze the telescopic hose 303d, so that the anhydrous alcohol in the telescopic hose 303d is injected into the water pipe 303f and flows through the water pipe 303f. The cleaning cloth 306f is sprayed through the spray head 303h on the connecting frame 303g. At this time, the cleaning cloth 306f enters the spraying range of the spray head 303h and is separated from the laser head 105, so that the anhydrous alcohol is sprayed onto the cleaning cloth 306f to sterilize the cleaning cloth 306f, and as the protective plate 305c moves, the guide block 305d will be separated from the extrusion disk 303e, so that the anhydrous alcohol inside the liquid storage tank 302 will be injected into the telescopic hose 303d again through the connecting pipe 303a and the one-way valve 303b.

[0067] When the laser head 105 completes laser cutting and the exhaust fan 208 is closed, the compressed spring 305e will drive the sealing plate 304 to move to the left for reset through its own elastic force, so that the sealing plate 304 will drive the movable plate 305b and the protective plate 305c to move to the left for reset through the fixed rod 305a. In the process of the protective plate 305c moving to the left for reset, the guide block 305d will contact the extrusion disk 303e again and squeeze the telescopic hose 303d through the extrusion disk 303e, so that after the telescopic hose 303d is squeezed, the anhydrous alcohol inside will be injected into the water pipe 303f and sprayed onto the cleaning cloth 306f through the spray head 303h on the connecting frame 303g, and the movable protective plate 305c will drive the rotating gear 306d to move through the supporting frame 306c. When the rotating gear When the wheel 306d moves inside the mounting frame 301, it meshes with the tooth groove 306a and rotates, so that the rotating gear 306d can drive the driven gear 306e inside the movable groove 306b to rotate, and the driven gear 306e can drive the cleaning cloth 306f to rotate after rotating, so that when the movable plate 305b drives the rotating cleaning cloth 306f to move to the bottom of the laser head 105, the rotating cleaning cloth 306f can clean the lens of the laser head 105, and the cleaning cloth 306f sprayed with anhydrous alcohol can increase the cleaning effect of the laser head 105, thereby completing the cleaning of the laser head 105 after use, and after the movable plate 305b and the protective plate 305c are completely reset, the protective plate 305c is located at the bottom of the laser head 105, so that the protective plate 305c can protect the laser head 105 when it is not in use.

[0068] In summary, the harmful exhaust gas generated during laser cutting is filtered by the activated carbon filter plate 204 inside the fixed frame 203, and the laser head 105 can be cooled by the filtered gas. The slide rail frame 102 is cleaned at the same time, and the laser head 105 is cleaned before and after use by the cleaning cloth 306f on the movable plate 305b. At the same time, the protective plate 305c can protect the laser head 105 when it is not in use.
