Description

Technical Field

[0001] This application relates to the field of laser cutting technology, and in particular to a dust removal device and processing 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] In related technologies, dust removal devices include an outer cover that partially surrounds a crossbeam and a cutting head. The outer cover is installed on the crossbeam and moves with it, and the dust inside the outer cover is drawn away in real time. However, due to unreasonable structural design, poor sealing of the air passage is prone to occur, resulting in poor dust removal effect. Utility Model Content

[0050] Reference Figure 1 and Figure 2 The dust removal device according to a first aspect embodiment of this application includes a base 100, a follower 200, and a telescopic tube 300. The follower 200 is connected to the base 100 and is capable of moving relative to the base 100 along a first direction (refer to...). Figure 1 For example, the first direction is the forward and backward direction. The follower 200 is provided with a first channel 210, which is used to communicate with the protective space, and the protective space is used to contain dust.

[0051] The telescopic tube 300 is connected to the base 100, and the telescopic tube 300 can extend or shorten in a first direction. The telescopic tube 300 is provided with a second channel 330, which is connected to the first channel 210. The second channel 330 is also used to connect to a positive pressure air source or a negative pressure air source.

[0052] The dust removal device according to the embodiments of this application has at least the following beneficial effects: during the process of the follower 200 moving relative to the base 100 in the first direction, the telescopic tube 300 will extend or shorten in the first direction, thereby ensuring that the first channel 210 and the second channel 330 are continuously connected, thereby ensuring that the first channel 210 can be connected to the positive pressure air source or the negative pressure air source to complete the dust removal in the protected space; since the second channel 330 is directly formed in the telescopic tube 300, and the second channel 330 is not formed by piecing together multiple parts, the second channel 330 is not easy to leak air, and the sealing effect of the air passage is better, which is conducive to improving the overall dust removal effect.

[0053] In related technologies, the second channel 330 is formed by splicing a bellows cover and a U-shaped groove. Gaps can easily exist between the bellows cover and the U-shaped groove, leading to gas or dust leakage and affecting the dust removal effect. In the embodiment of this application, the second channel 330 is directly formed by a telescopic tube 300, which has better sealing performance and makes it less likely for gas or dust to leak from the air passage.

[0054] It should be noted that, referring to Figure 6 The outer casing 800 has a protective space inside, and the crossbeam 600 and the cutting head are located in the protective space. The protective space is a semi-enclosed space with an opening for laser emission.

[0055] Reference Figure 2 In some embodiments of this application, the first channel 210 is provided with a first opening 211, a second opening 212, and a third opening 213. The third opening 213 is used to communicate with the protective space. The telescopic tube 300 includes a first fitting 310 and a second fitting 320. The first fitting 310 is connected to the base 100 and is provided with a first sub-channel 331. One end of the first sub-channel 331 is connected to the first opening 211.

[0056] The second pipe fitting 320 is connected to the base 100. The second pipe fitting 320 is provided with a second sub-channel 332. One end of the second sub-channel 332 is connected to the second opening 212, and the other end of the second sub-channel 332 is used to connect to a positive pressure air source or a negative pressure air source. The second sub-channel 332 and the first sub-channel 331 together form the second channel 330.

[0057] By dividing the telescopic pipe 300 into a first fitting 310 and a second fitting 320, the amount of expansion and contraction of a single fitting can be reduced, the degree of deformation of the fitting is lower, and the fitting is less prone to damage. This helps to extend the service life of the telescopic pipe 300 and reduce maintenance costs.

[0058] Specifically, the first pipe 310 is supported by the base 100, and the end of the first pipe 310 away from the follower 200 is fixedly connected to the base 100 by fasteners. The second pipe 320 is supported by the base 100, and the end of the second pipe 320 away from the follower 200 is fixedly connected to the base 100 by fasteners.

[0059] In another embodiment, the telescopic tube 300 may also include only the first tube 310, in which case the displacement of the follower 200 is provided by the deformation of the first tube 310.

[0060] In some embodiments of this application, the first fitting 310 includes a first organ pipe, and the second fitting 320 includes a second organ pipe.

[0061] The first and second organ pipes can well meet the usage requirements and have low operating costs, which helps to reduce the equipment cost of the dust removal device.

[0062] In another embodiment, the first fitting 310 and the second fitting 320 may also be metal hoses.

[0063] Reference Figure 2 In the improved version of the above embodiment, the other end of the first sub-channel 331 is closed.

[0064] By sealing off the other end of the first sub-channel 331 and connecting the other end of the second sub-channel 332 separately to a positive or negative pressure air source, the structure can be simplified and the equipment cost reduced.

[0065] In another embodiment, the other end of the first sub-channel 331 can also be used to connect with a positive pressure air source or a negative pressure air source. In this case, the other end of the first sub-channel 331 and the other end of the second sub-channel 332 can simultaneously intake or exhaust air, resulting in higher dust removal efficiency.

[0066] Reference Figures 3 to 5 In some embodiments of this application, the base 100 is provided with a groove 110, the length direction of the groove 110 is arranged along the first direction, and the telescopic tube 300 is located in the groove 110.

[0067] By setting the groove 110, the telescopic tube 300 can be extended along the first direction. Thus, the telescopic tube 300 will not bend arbitrarily, but will only extend and retract along the first direction. The deformation of the telescopic tube 300 becomes controllable, and the telescopic tube 300 is not easily damaged.

[0068] Reference Figures 3 to 5 In the above embodiments, at least a portion of the follower 200 is located in the groove 110, and the follower 200 is able to slide or roll along the first direction on the inner surface 120 of the groove 110.

[0069] By allowing the follower 200 to slide or roll along the first direction on the inner surface 120 of the groove 110, the movement direction of the follower 200 can be better constrained, so that the follower 200 moves along the first direction.

[0070] Reference Figure 4 and Figure 5 In the improved embodiment described above, the inner surface 120 of the groove 110 includes a bottom surface 121, and the dust removal device also includes a first roller 410. The first roller 410 is rotatably connected to the follower 200, and the first roller 410 can roll along the bottom surface 121.

[0071] By making the first roller 410 roll along the bottom surface 121, the follower 200 and the inner surface 120 can be rolled together in the first direction.

[0072] Specifically, two or more first rollers 410 can be provided, so that the follower 200 can roll stably along the first direction.

[0073] Reference Figure 4 and Figure 5 In the improved embodiment described above, the inner surface 120 of the groove 110 includes a first side 122 and a second side 123. The first side 122 and the second side 123 are opposite to each other and spaced apart. The dust removal device also includes a second roller 420. There are two or more second rollers 420. The second rollers 420 are rotatably connected to the follower 200. At least one second roller 420 can roll along the first side 122, and the remaining second rollers 420 can roll along the second side 123.

[0074] By causing at least one second roller 420 to roll along the first side 122 and the remaining second rollers 420 to roll along the second side 123, the movement direction of the follower 200 can be better constrained, allowing the follower 200 to move along the first direction.

[0075] Reference Figure 5 In some embodiments of this application, the base 100 includes a base plate 130, a first upright plate 140 and a second upright plate 150. The first upright plate 140 and the second upright plate 150 are arranged side by side and spaced apart. Both the first upright plate 140 and the second upright plate 150 are connected to the base plate 130. The first upright plate 140, the second upright plate 150 and the base plate 130 enclose a groove 110.

[0076] The groove 110 is formed by the first upright plate 140, the second upright plate 150 and the base plate 130, which can save materials and reduce the production cost of the base 100.

[0077] Specifically, the first upright plate 140, the second upright plate 150 and the base plate 130 can be integrally formed, or the first upright plate 140 and the second upright plate 150 can be welded and fixed to the base plate 130.

[0078] Reference Figure 6 The processing equipment according to a second aspect embodiment of this application includes a dust removal device, a bed 500, a crossbeam 600, and a processing device 700. The bed 500 is used to carry products, and a base 100 is mounted on the bed 500. The crossbeam 600 is movable relative to the bed 500, and a follower 200 is mounted on the crossbeam 600. The processing device 700 is mounted on the crossbeam 600 and is used to process the products carried by the bed 500.
