Abstract
Description
Technical Field
[0001] This application relates to the field of laser cutting technology, and in particular to a dust removal device and laser cutting equipment. Background Technology
[0002] Laser cutting utilizes a high-power-density laser beam to irradiate the material being cut, rapidly heating it to its vaporization temperature. Simultaneously, a high-speed gas stream, coaxial with the laser beam, blows away the molten material, creating a hole in the workpiece. As the laser beam moves, the holes connect, forming a very narrow kerf, thus completing the cutting process. Laser cutting offers advantages such as high cutting precision, narrow kerf, smooth surface, and a small heat-affected zone.
[0003] Single-platform planar laser cutting equipment, due to the limitations of its original structure, cannot form a closed working space, resulting in poor machine protection and a poor working environment. Specifically: 1. Molten slag and arc light are not shielded during cutting, easily splattering everywhere; 2. The fumes generated during cutting easily escape and cannot be effectively removed by the ventilation system.
[0004] In related technologies, the crossbeam and laser head are placed in a semi-enclosed outer casing, and dust removal is achieved by extracting gas from inside the casing. However, when the bed has an exhaust duct, the dust extraction inside the casing is difficult to coordinate effectively with the exhaust duct of the bed, resulting in poor dust removal efficiency inside the casing.

[0052] Reference Figure 1 and Figure 2 The dust removal device according to a first aspect embodiment of this application includes a crossbeam 100, a laser head 200, an outer cover 300, and a blower 410. The laser head 200 is used to emit laser light and is mounted on the crossbeam 100. The outer cover 300 is mounted on the crossbeam 100 and has a receiving cavity 320, within which both the crossbeam 100 and the laser head 200 are located. The receiving cavity 320 has an opening 321 for laser emission. The blower 410 has a blowing channel 411, one end of which communicates with the receiving cavity 320, and the other end of which communicates with a positive pressure air source.
[0053] The dust removal device according to the embodiments of this application has at least the following beneficial effects: air is blown into the accommodating cavity 320 through the air blowing channel 411, and the dust inside the outer cover 300 can flow out from the opening 321 with the airflow; when the bed 500 has an exhaust channel 510 (see...) Figure 2 The air blowing channel 411 can be combined with the air extraction channel 510 of the bed 500 to form a stable dust removal airflow, and the dust removal effect inside the outer cover 300 is better.
[0054] It should be noted that the dust removal device can form a good cooperation with the exhaust duct 510 of the bed 500, which means that the dust removal device has the potential or ability to form a stable dust removal airflow when it is used in conjunction with the bed 500 which has the exhaust duct 510.
[0055] It should be noted that the laser head 200 generally includes a focusing lens, a protective lens, and a nozzle.
[0056] Specifically, positive pressure air sources can be generated by air compressors or blowers, while negative pressure air sources can be generated by vacuum pumps or negative pressure fans.
[0057] Reference Figure 2 In some embodiments of this application, the dust removal device further includes a bed 500, which is provided with an exhaust duct 510. One end of the exhaust duct 510 is connected to the opening 321, and the other end of the exhaust duct 510 is used to connect to a negative pressure air source. A crossbeam 100 is installed on the bed 500.
[0058] By setting an exhaust duct 510 on the bed 500, the air blowing from the air blowing duct 411 can cooperate with the exhaust duct 510 of the bed 500 to form a stable dust removal airflow, resulting in better dust removal effect inside the outer cover 300.
[0059] Reference Figure 2 and Figure 3 In some embodiments of this application, the dust removal device further includes a telescopic pipe 420, which has a transfer channel 421. One end of the transfer channel 421 is connected to the other end of the air blowing channel 411, and the other end of the transfer channel 421 is used to connect to a positive pressure air source. The crossbeam 100 can be positioned relative to the bed 500 along a first direction (refer to...). Figure 3 (For example, if the first direction is the front-back direction), the telescopic tube 420 can extend or shorten along the first direction.
[0060] By setting the telescopic tube 420, the blower 410 can move along the first direction with the crossbeam 100, and the blower channel 411 can continuously blow air into the accommodating cavity 320, resulting in a better dust removal effect inside the outer cover 300.
[0061] Specifically, the telescopic tube 420 can be a bellows tube or a metal flexible tube.
[0062] Reference Figure 2 In some embodiments of this application, the outer cover 300 includes a connecting seat 310, a body 330, a first telescopic cover 350, and a second telescopic cover 360. The connecting seat 310 is mounted on the crossbeam 100, and the connecting seat 310 is oriented relative to the crossbeam 100 along a second direction (refer to...). Figure 2 (For example, the second direction is the left and right direction) movement. The laser head 200 is mounted on the connector 310.
[0063] The main body 330 is mounted on the crossbeam 100. The main body 330 is provided with a clearance hole 332, which communicates with the receiving cavity 320 and also communicates with the space outside the outer cover 300. At least a portion of the connecting seat 310 is located in the clearance hole 332, and there is a gap between the connecting seat 310 and the inner surface of the clearance hole 332. Along the second direction, the connecting seat 310 divides the clearance hole 332 into a first region 333 and a second region 334.
[0064] The first telescopic cover 350 is used to enclose the first region 333. One end of the first telescopic cover 350 is connected to the connecting seat 310, and the other end of the first telescopic cover 350 is connected to the main body 330. The second telescopic cover 360 is used to enclose the second region 334. One end of the second telescopic cover 360 is connected to the connecting seat 310, and the other end of the second telescopic cover 360 is connected to the main body 330.
[0065] By providing the clearance hole 332 and the connecting seat 310, the moving laser head 200 can easily maintain electrical and optical connections with the equipment outside the outer casing 300. By providing the first telescopic cover 350 and the second telescopic cover 360, the clearance hole 332 can be closed when the connecting seat 310 moves relative to the crossbeam 100, thereby preventing dust from overflowing from the accommodating cavity 320.
[0066] Reference Figure 3 In the improved embodiment described above, the first telescopic cover 350 includes a first accordion cover, and the second telescopic cover 360 includes a second accordion cover.
[0067] Both the first and second bellows covers can meet the usage requirements well, and the usage cost is low, which helps to reduce the equipment cost of the dust removal device.
[0068] In another embodiment, the first telescopic cover 350 and the second telescopic cover 360 may also be made of metal flexible hoses.
[0069] Reference Figure 1 In some embodiments of this application, the outer cover 300 includes a body 330 and a door panel 370. The body 330 is mounted on the crossbeam 100 and has an inspection hole 391 that communicates with the receiving cavity 320 and also with the space outside the outer cover 300. The door panel 370 is connected to the body 330 and is movable relative to the body 330 to close or open the inspection hole 391.
[0070] By providing inspection hole 391 and door panel 370, the laser head 200 can be inspected when needed, and dust can be prevented from overflowing when the laser head 200 is working, thus making the dust removal device more convenient to use.
[0071] Reference Figure 1In the improved embodiment described above, one end of the door panel 370 is rotatably connected to the body 330 to close or open the inspection hole 391.
[0072] The door panel 370 can be opened by rotating it, making it quite convenient to use.
[0073] Specifically, the upper end of the door panel 370 is rotatably connected to the body 330 via a hinge. When the door panel 370 is opened, it flips upward, thereby making full use of the space above the body 330, and the door panel 370 does not easily obstruct staff when it is open.
[0074] In another embodiment, the door panel 370 may also be slidably connected to the body 330.
[0075] Reference Figure 1 and Figure 3 It should be noted that, Figure 1 The observation hole 371 in the middle is not fitted with filter plate 380. Figure 3 The observation hole 371 in the door panel 370 is equipped with a filter plate 380. In some embodiments of this application, the outer cover 300 further includes a filter plate 380, and the door panel 370 is provided with an observation hole 371. The observation hole 371 communicates with the accommodating cavity 320 and also communicates with the space outside the outer cover 300. The filter plate 380 is installed on the door panel 370 and closes the observation hole 371.
[0076] The filter plate 380 can filter scattered light generated by the laser while allowing workers to process the pipes. The use of the dust collection device is also made easier by incorporating the filter plate 380.
[0077] Reference Figure 1 and Figure 3 In the improved embodiment described above, the door panel 370 is provided with two or more observation holes 371, and the number of filter plates 380 is the same as the number of observation holes 371. The filter plates 380 are used to close the observation holes 371 one by one.
[0078] By setting two or more filter plates 380, the processing situation inside the accommodating cavity 320 can be observed more comprehensively, and the dust removal device is more convenient to use.
[0079] Specifically, the number of observation holes 371 can be two, three, four, or other numbers.
[0080] Reference Figure 1 In some embodiments of this application, the body 330 includes a first end 331, and the door panel 370 includes a second end 372. The first end 331 and the second end 372 together form an opening 321. The outer cover 300 also includes a first curtain 340, which is installed at the first end 331. A second curtain 390 is installed at the second end 372.
[0081] By setting the first curtain 340 and the second curtain 390, the protective range of the outer cover 300 can be expanded. The first curtain 340 and the second curtain 390 can close the gap between the outer cover 300 and the bed 500, and the dust removal device has a better dust prevention effect.
[0082] Reference Figure 3 According to a second aspect of this application, a laser cutting apparatus includes a dust removal device and a laser 600, the laser 600 being used to generate laser light, the laser light being capable of propagating to a laser head 200.
[0083] The laser cutting equipment according to the embodiments of this application has at least the following beneficial effects: by using the above-mentioned dust removal device, it can form a good cooperation with the dust extraction function of the bed 500, which is conducive to improving the dust removal effect inside the outer cover 300, thereby improving the protective capability of the laser cutting equipment.
[0084] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
