Description

Technical Field

[0001] This application relates to the field of laser dust removal equipment technology, and in particular to a dust removal device and a laser device. Background Technology

[0002] In XBC battery technology, laser patterning is a crucial component and also one of the bottleneck technologies. Because XBC batteries have a high laser patterning ratio (more than 50% of the battery area), a large amount of dust is generated during the large-area laser patterning process using laser cutting. If this dust is not removed in time, it may obstruct the subsequent laser from reaching the material surface, resulting in insufficient incident laser energy and process instability. Therefore, a dust removal device is needed for fumigation and dust removal.

[0003] In related technologies, a dust removal hood is installed around the laser processing table of a laser device. An air inlet is set on one side of the dust removal hood, and an air extraction port is set on the opposite side. Air is blown through the air inlet to remove the fumes so that the air extraction port on the other side can remove the fumes. However, when the laser is processing in an area far from the air extraction port, the generated laser fumes cannot be completely removed. This will block the laser from hitting the surface of the workpiece, resulting in insufficient laser energy in some areas of the workpiece, which in turn affects the laser's film-opening effect.

[0034] like Figures 1-2 As shown, in a first aspect, embodiments of this application may provide a dust removal device, which may include:

[0035] The dust removal body 1 is provided with a first dust removal chamber 11, which is located above the workpiece 3 to be processed.

[0036] Dust removal component 2 is movably mounted on dust removal body 1;

[0037] During the process of cutting the workpiece 3 by the laser 4 along a predetermined path, the dust removal component 2 moves synchronously with the laser 4 along the predetermined path to suck up the dust generated during the cutting process.

[0038] In this embodiment, by movably mounting the dust removal component 2 on the dust removal body 1 and moving synchronously with the predetermined path of laser cutting, the dust generated by laser cutting the workpiece 3 can be immediately removed by the dust removal component 2. This allows the dust removal component 2 to effectively remove a large amount of dust generated during the large-area film opening process of laser cutting, reducing the situation where dust blocks the laser cutting surface, thereby improving the processing quality of large-area film opening by laser cutting.

[0039] In an optional embodiment, the dust removal assembly 2 includes a first side plate 21 and a second side plate 22, with a dust removal sub-cavity 23 formed between the first side plate 21 and the second side plate 22; the first side plate 21 has a plurality of air inlets 2121 for air intake on the side facing the second side plate 22, and the second side plate 22 has a plurality of air extraction ports 2221 for air extraction on the side facing the first side plate 21; wherein, the dust removal sub-cavity 23 is located in the first dust removal cavity 11, and the first side plate 21 and the second side plate 22 are synchronously moved and disposed on the dust removal body 1.

[0040] In this embodiment, during the laser cutting process of the workpiece 3, the processing area 31 formed by the laser 4 will continuously move. The first side plate 21 and the second side plate 22 move synchronously on the dust removal body 1, so that the processing area 31 is always kept below the dust removal sub-cavity 23. The first side plate 21 is provided with an air inlet 2121 and the second side plate 22 is provided with an air extraction port 2221. The gas blows the dust generated in the processing area 31 through the air inlet 2121, and then the air extraction port 2221 removes the dust, which effectively improves the dust removal effect.

[0041] In an optional embodiment, a first connecting plate 24 is provided on the first side plate 21, and a second connecting plate 25 is provided on the second side plate 22; the side of the first side plate 21 away from the first connecting plate 24 and the side of the second side plate 22 away from the second connecting plate 25 are inclined to each other; wherein, the first connecting plate 24 and the second connecting plate 25 are synchronously moved and disposed on the dust removal body 1.

[0042] In this embodiment, since the side of the first side plate 21 away from the first connecting plate 24 and the side of the second side plate 22 away from the second connecting plate 25 are inclined to each other, dust can be blown from bottom to top, thereby improving the dust removal effect and further reducing the amount of dust falling on the workpiece 3, thus improving the mold opening effect of the large-area laser 4.

[0043] In an optional embodiment, the dust removal body 1 is provided with a driving component and a first guide rail 12 and a second guide rail 13 that are parallel to each other; one end of the first connecting plate 24 and the second connecting plate 25 is slidably disposed on the first guide rail 12 via the first slider 14, and the other end is disposed on the second guide rail 13 via the second slider 15; the driving component is used to drive the first connecting plate 24 and the second connecting plate 25 to move synchronously.

[0044] In this embodiment, the driving component can drive the first connecting plate 24 and the second connecting plate 25 to move synchronously on the first guide rail 12 and the second guide rail 13. Therefore, the first guide rail 12 and the second guide rail 13, which are arranged parallel to each other, not only guide the first connecting plate 24 and the second connecting plate 25, but also enable the first connecting plate 24 and the second connecting plate 25 to move synchronously on the dust removal body 1. It should be noted that, in this embodiment, the driving component can be a lead screw motor to drive the synchronous movement of the first connecting plate 24 and the second connecting plate 25, or it can be a linear guide rail to drive the synchronous movement of the first connecting plate 24 and the second connecting plate 25.

[0045] In an optional embodiment, the first side plate 21 includes a first mounting plate 211 and an air intake plate 212. The first mounting plate 211 is provided with a first connecting cavity 2111. A plurality of air inlets 2121 are provided on the air intake plate 212, and the plurality of air inlets 2121 are all connected to the first connecting cavity 2111. An air pump 213 is provided on the first mounting plate 211, and the air pump 213 is connected to the first connecting cavity 2111.

[0046] In this embodiment, several air inlets 2121 are connected to the first connecting cavity 2111. The air pump 213 is connected to the first connecting cavity 2111. The gas generated by the air pump 213 first enters the first connecting cavity 2111 and then is discharged from several air inlets 2121, thereby blowing up a large amount of dust generated by laser processing so that the air extraction port 2221 can extract the dust.

[0047] In an optional embodiment, the second side plate 22 includes a second mounting plate 221 and an exhaust plate 222. The second mounting plate 221 is provided with a second connecting cavity 2211. A plurality of exhaust ports 2221 are provided on the exhaust plate 222, and the plurality of exhaust ports 2221 are all connected to the second connecting cavity 2211. A dust extraction system 223 is provided on the second mounting plate 221, and the dust extraction system 223 is connected to the second connecting cavity 2211.

[0048] In this embodiment, several air extraction ports 2221 are connected to the second connecting cavity 2211. The dust extraction system 223, through its connection with the second connecting cavity 2211, can draw dust into the second connecting cavity 2211 through the air extraction ports 2221, and then the dust in the second connecting cavity 2211 is drawn away by the dust extraction system 223.

[0049] In an optional embodiment, the processing area 31 formed by laser cutting the workpiece 3 is 20-100mm away from the first side plate 21; and / or the processing area 31 formed by laser cutting the workpiece 3 is 20-100mm away from the second side plate 22.

[0050] In this embodiment, the distance between the first side plate 21 and the processing area 31 and / or the distance between the second side plate 22 and the processing area 31 is maintained at 20~100mm, which can effectively ensure the dust removal effect; in this embodiment, the distance between the first side plate 21 and the processing area 31 can be 50mm, and / or the distance between the second side plate 22 and the processing area 31 can be 50mm.

[0051] In an optional embodiment, a plurality of air inlets 2121 are evenly spaced; and / or a plurality of air extraction ports 2221 are evenly spaced. The evenly spaced air inlets 2121 and air extraction ports 2221 can effectively improve the dust removal effect.

[0052] In an optional embodiment, a dust removal cover 5 is also provided on the periphery of the dust removal body 1, and the dust removal cover 5 encloses and forms a second dust removal cavity 51 that communicates with the first dust removal cavity 11; the dust removal cover 5 is also provided with a clearance through hole 52 to facilitate the passage of the laser 4.

[0053] In this embodiment, the dust removal cover 5 can block the dust that has not been removed in the first dust removal chamber 11 and the second dust removal chamber 51 to prevent the dust from overflowing into the external environment and threatening personnel and the environment; while the clearance through hole 52 allows the laser 4 to pass through and process the workpiece 3.
