Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a dust treatment device for laser cutting equipment. Background Art

[0002] The traditional cutting method is to cut the workpiece through relative movement between cutting tools such as cutting bars and cutting discs and the workpiece. With the development of technology, laser cutting has begun to increase and gradually replaced traditional cutting. Laser cutting uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporated to form holes. As the beam moves across the material, the holes continuously form a very narrow slit, completing the cutting of the material.

[0003] Application number 202221876021.6 is a dust treatment device for laser cutting of printed circuit boards, comprising a device base, the device base being provided with a processing chamber; a processing platform, the processing platform being arranged in the processing chamber; a lens, the lens being mounted above the processing platform; a dust treatment assembly, the dust treatment assembly being mounted between the lens and the processing platform; the dust treatment assembly comprising a dust extraction port body, an adjustment mounting plate mounted on the dust extraction port body, a light-transmitting dust shield cover, and an ion air blade; the adjustment mounting plate being mounted on the device base, an air inlet being provided at the bottom of the dust extraction port body, the interior of the dust extraction port body being a cavity, the air inlet being connected to the fan through the cavity. The laser beam is directed through the light-transmitting dust shield cover toward the circuit board mounted on the processing platform for laser cutting, and the dust is blocked by the light-transmitting baffle in a relatively closed dust blocking chamber to prevent dust from adhering to the product surface.

[0004] This technical solution uses a square frame and a transparent cover to blow and exhaust the laser cutting area to remove dust. Although the transparent cover can pass through the laser beam, the transparent material also has a certain refractive index, which can easily cause the laser beam to deviate or diffuse, thereby increasing the possibility of slag. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a dust treatment device for laser cutting equipment to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dust treatment device for laser cutting equipment, comprising a device body, a gantry slide and a laser head, a bracket connected to the lower portion of the outer surface of the gantry slide, and a sleeve passing through the middle of the top of the bracket, a brush connected to the bottom of the sleeve, a back plate sleeved on the outside of the laser head, and ventilation holes on both sides of the top of the back plate; a dust removal fan is installed on one side of the device body, and the air outlet end of the dust removal fan is connected to a dust delivery trough, and a conveying pipe is connected between the dust removal fan and the sleeve.

[0007] By adopting the above technical solution, the sleeve will block the laser head on all sides, and the brush will block the cutting area on all sides, which will not block the laser beam, prevent the staff from touching the laser beam, and prevent smoke and dust from floating around. When the smoke and dust are removed, the inside of the sleeve is in a negative pressure state. At this time, the outside air enters the sleeve from the four sides of the brush and the top of the ventilation hole. The air entering the sleeve from the brush area can take away the smoke and dust, thereby achieving the effect of removing smoke and dust. The air entering the sleeve from the top of the ventilation hole can take away the heat on the surface of the laser head, thereby dissipating the heat of the laser head. The gantry slide drives the laser head back and forth while driving the bracket back and forth, so that the sleeve moves back and forth with the laser head. When the laser head moves left and right, the laser head transmits power to the sleeve through the anti-plate, so that the sleeve moves with the laser head and slides on the bracket. The setting of the anti-plate avoids collision between the laser head and the sleeve, and ensures that the laser head is always located at the center of the sleeve, avoiding contact between the laser beam and the sleeve or the brush.

[0008] Furthermore, the delivery pipe is a stainless steel hose.

[0009] By adopting the above technical solution, since the delivery pipe is a stainless steel hose, it can adapt to the displacement of the sleeve to avoid the pipe being broken, and can also prevent the delivery pipe from being affected by high-temperature flue gas.

[0010] Furthermore, the sleeve is slidably connected to the bracket, and the abutment plate is slidably connected to the sleeve.

[0011] By adopting the above technical solution, when the laser head moves left and right, the laser head transmits power to the sleeve through the abutment plate, so that the sleeve moves along with the laser head and slides on the bracket. After the electric cylinder is started, the height of the laser head can be adjusted, and at the same time the abutment plate slides in the sleeve.

[0012] Furthermore, a plurality of ventilation holes are provided, and the plurality of ventilation holes are distributed in a ring array.

[0013] By adopting the above technical solution, external air enters the sleeve from the surrounding of the brush and the top of the ventilation hole. The air entering the sleeve from the top of the ventilation hole can take away the heat from the surface of the laser head, thereby dissipating the heat of the laser head.

[0014] Furthermore, the brush is made of steel wire and has a circular ring shape.

[0015] By adopting the above technical solution, the brush will block the four sides of the cutting area, thereby preventing smoke and dust from floating around. The brush is made of steel wire, which is a heat-resistant and fire-proof material, thereby preventing the heat radiated by the laser beam to the surrounding area from causing the brush to melt or catch fire.

[0016] Furthermore, the sleeve is made of transparent PC material, and the abutment plate is made of Teflon material.

[0017] By adopting the above technical solution, the sleeve is made of transparent PC, which is convenient for staff to watch and prevent them from being exposed to the laser beam. It is also made of heat-resistant and fire-proof material, thereby preventing the heat radiated by the laser beam to the surrounding area from causing the sleeve to melt or catch fire. Since the abutment plate is made of Teflon material, the wear between the abutment plate and the sleeve is reduced.

[0018] Furthermore, the gantry slide is installed on both sides of the top of the device body, and an electric cylinder is installed at the output end of the gantry slide, and the laser head is installed at the output end of the electric cylinder.

[0019] By adopting the above technical solution, the laser head emits a laser beam to cut the plate after it is started, the gantry slide drives the laser head to move forward, backward, left and right after it is started, and the height of the laser head can be adjusted after the electric cylinder is started.

[0020] Furthermore, the laser head is located inside the sleeve.

[0021] By adopting the above technical solution, the laser head is always located at the center of the sleeve, avoiding the laser beam from contacting the sleeve or the brush. The sleeve is convenient for workers to watch and avoids workers from contacting the laser beam.

[0022] Furthermore, threaded rods are passed through both sides of the top of the bracket, and one end of the threaded rod is connected to a handwheel.

[0023] By adopting the above technical solution, the staff reverses the handwheel to reverse the threaded rod. After the threaded rod is reversed, the bracket, sleeve and brush are moved down to adapt to plates of different thicknesses. At this time, the staff pays attention to the position of the brush. A certain gap should be left between the brush and the plate to prevent the brush from scratching the top of the plate.

[0024] Furthermore, the threaded rod is rotatably connected to the gantry slide, and the bracket is threadedly connected to the threaded rod.

[0025] By adopting the above technical solution, the operator rotates the handwheel to rotate the threaded rod and then moves the bracket upward. The upward movement of the bracket drives the sleeve and the brush to move upward. Then the operator places the plate to be cut on the top of the device body.

[0026] In summary, the present invention has the following beneficial effects:

[0027] The utility model is provided with a bracket, a sleeve, a back plate, a ventilation hole and a brush. The sleeve blocks the laser head on all sides, and the brush blocks the cutting area on all sides, which will not block the laser beam, prevent the staff from touching the laser beam, and prevent smoke and dust from floating around. When the smoke and dust are extracted, the inside of the sleeve is in a negative pressure state. At this time, the outside air enters the sleeve from the surrounding of the brush and the top of the ventilation hole. The air entering the sleeve from the brush area can take away the smoke and dust, thereby achieving the effect of removing smoke and dust. The air entering the sleeve from the top of the ventilation hole can take away the surface of the laser head The heat on the surface is dissipated, thereby dissipating the heat of the laser head; the gantry slide drives the laser head to move back and forth while driving the bracket to move back and forth, so that the sleeve moves back and forth with the laser head. When the laser head moves left and right, the laser head transmits power to the sleeve through the abutment plate, so that the sleeve moves with the laser head and slides on the bracket. The setting of the abutment plate avoids collision between the laser head and the sleeve, and ensures that the laser head is always located at the center of the sleeve, avoiding contact between the laser beam and the sleeve or the brush; it does not affect the processing accuracy, and can improve safety and increase heat dissipation efficiency.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] The following describes an embodiment of the present invention based on its overall structure.

[0035] Example 1:

[0036] A dust treatment device for laser cutting equipment, such as Figures 1-4As shown, it includes a device body 1, a gantry slide 2 and a laser head 3. A bracket 8 is connected to the lower side of the outer surface of the gantry slide 2. A sleeve 9 runs through the middle of the top of the bracket 8. The sleeve 9 is made of transparent PC material. The sleeve 9 is transparent PC, which is convenient for staff to watch and prevent staff from being exposed to the laser beam; the sleeve 9 is slidably connected to the bracket 8, and a brush 12 is connected to the bottom of the sleeve 9. The brush 12 is made of steel wire and is in a circular shape. The sleeve 9 blocks the laser head 3 on all sides, and the brush 12 blocks the cutting area on all sides, thereby preventing smoke and dust from floating around. Since the brush 12 is made of steel wire and the sleeve 9 is made of PC material, both are heat-resistant and fire-proof materials, thereby preventing the heat radiated to the surrounding by the laser beam from causing the brush 12 and the sleeve 9 to melt or catch fire; the laser head 3 is externally sleeved with a butt plate 10, and the laser The head 3 transmits power to the sleeve 9 through the anti-plate 10, so that the sleeve 9 moves along with the laser head 3 and the sleeve 9 slides on the bracket 8. The setting of the anti-plate 10 avoids collision between the laser head 3 and the sleeve 9, and ensures that the laser head 3 is always located at the center of the sleeve 9, avoiding contact between the laser beam and the sleeve 9 or the brush 12; the anti-plate 10 is made of Teflon material, and the anti-plate 10 is slidably connected to the sleeve 9. The anti-plate 10 slides in the sleeve 9. Since the anti-plate 10 is made of Teflon material, the wear between the anti-plate 10 and the sleeve 9 is reduced; ventilation holes 11 are provided on both sides of the top of the anti-plate 10, and a plurality of ventilation holes 11 are provided, and the plurality of ventilation holes 11 are distributed in a circular array. The air entering the sleeve 9 from the top of the ventilation hole 11 can take away the heat from the surface of the laser head 3, thereby dissipating the heat of the laser head 3;

[0037] A dust removal fan 5 is installed on one side of the device body 1. A conveying pipe 7 is connected between the dust removal fan 5 and the sleeve 9. The conveying pipe 7 is a stainless steel hose. After the dust removal fan 5 is started, the smoke in the sleeve 9 is sucked out through the conveying pipe 7. Since the conveying pipe 7 is a stainless steel hose, it can adapt to the displacement of the sleeve 9 to avoid the pipeline being broken, and can also avoid the high-temperature flue gas causing the conveying pipe 7 to be affected; the air outlet of the dust removal fan 5 is connected to the ash delivery trough 6, and the smoke is sent into the processing equipment through the ash delivery trough 6 to process the dust and flue gas and then discharge them to avoid polluting the environment.

[0038] See Figure 1 and Figure 2 In the above embodiment, the gantry slide 2 is installed on both sides of the top of the device body 1. After the gantry slide 2 is started, it drives the laser head 3 to move forward, backward, left and right; the output end of the gantry slide 2 is installed with an electric cylinder 4, which can adjust the height of the laser head 3 after the electric cylinder 4 is started; the laser head 3 is installed at the output end of the electric cylinder 4, and the laser head 3 is located inside the sleeve 9. After the laser head 3 is started, it emits a laser beam to cut the plate.

[0039] Example 2:

[0040] On the basis of the above embodiment 1, in order to facilitate adaptation to plates of different thicknesses, the following settings are now adopted.

[0041] See Figure 1 and Figure 4 In the above embodiment, threaded rods 14 are passed through both sides of the top of the bracket 8, one end of the threaded rod 14 is connected to a handwheel 13, the threaded rod 14 is rotatably connected to the gantry slide 2, and the bracket 8 is threadedly connected to the threaded rod 14. The staff places the plate to be cut on the top of the device body 1, and then the staff reverses the handwheel 13 to reverse the threaded rod 14. After the threaded rod 14 is reversed, the bracket 8, sleeve 9 and brush 12 are moved downward to adapt to plates of different thicknesses.

[0042] The implementation principle of the present utility model is as follows: first, the staff rotates the hand wheel 13 to rotate the threaded rod 14 and then moves the bracket 8 upward, and the upward movement of the bracket 8 drives the sleeve 9 and the brush 12 to move upward. Then, the staff places the plate to be cut on the top of the device body 1, and then the staff reverses the hand wheel 13 to reverse the threaded rod 14. After the threaded rod 14 is reversed, the bracket 8, sleeve 9 and brush 12 move downward to adapt to plates of different thicknesses. At this time, the staff pays attention to the position of the brush 12. A certain gap should be left between the brush 12 and the plate to prevent the brush 12 from scratching the top of the plate;

[0043] After the preparation work is completed, the staff turns on the gantry slide 2, laser head 3, electric cylinder 4 and dust removal fan 5. After the laser head 3 is started, it emits a laser beam to cut the plate. The sleeve 9 blocks the laser head 3 on all sides, and the brush 12 blocks the cutting area on all sides to prevent smoke and dust from drifting freely. Since the brush 12 is made of steel wire and the sleeve 9 is made of PC, both are heat-resistant and fire-proof materials, the heat radiated by the laser beam to the surrounding area may not cause the brush 12 and sleeve 9 to melt or catch fire. The sleeve 9 is made of transparent PC, which is convenient for staff to see and prevents staff from being exposed to the laser beam.

[0044] After the gantry slide 2 is started, it drives the laser head 3 to move forward, backward, left and right. The gantry slide 2 drives the laser head 3 to move forward and backward while driving the bracket 8 to move forward and backward, so that the sleeve 9 moves forward and backward with the laser head 3. When the laser head 3 moves left and right, the laser head 3 transmits power to the sleeve 9 through the stop plate 10, so that the sleeve 9 moves together with the laser head 3 and slides on the bracket 8. The setting of the stop plate 10 avoids collision between the laser head 3 and the sleeve 9, and ensures that the laser head 3 is always located at the center of the sleeve 9, avoiding contact between the laser beam and the sleeve 9 or the brush 12. After the electric cylinder 4 is started, the height of the laser head 3 can be adjusted, and the stop plate 10 slides in the sleeve 9. Since the stop plate 10 is made of Teflon material, the wear between the stop plate 10 and the sleeve 9 is reduced;

[0045] After the dust removal fan 5 is started, the smoke and dust in the sleeve 9 are drawn out through the conveying pipe 7. When the smoke and dust are drawn out, the inside of the sleeve 9 is in a negative pressure state. At this time, the outside air enters the sleeve 9 from the four sides of the brush 12 and the top of the ventilation hole 11. The air entering the sleeve 9 from the brush 12 area can take away the smoke and dust, thereby achieving the effect of removing smoke and dust. The air entering the sleeve 9 from the top of the ventilation hole 11 can take away the heat on the surface of the laser head 3, thereby dissipating the heat of the laser head 3. Moreover, since the conveying pipe 7 is a stainless steel hose, it can adapt to the displacement of the sleeve 9 to avoid the pipeline being broken, and can also avoid the high-temperature flue gas causing the conveying pipe 7 to be affected. Afterwards, the smoke and dust are sent to the processing equipment through the ash air trough 6 to treat the dust and flue gas and then be discharged to avoid polluting the environment.
