[0030] In the process of making batteries in the new energy lithium battery industry, pole piece cutting is a very important process. Currently, laser die cutting is usually used for cutting. However, during the cutting process of existing cutting equipment, a large amount of high-temperature dust particles sputtered by laser cutting will adhere to the edge of the cutting port. After a long period of operation, the accumulated powder condenses into powder columns, which will cause the pole piece to be lifted out of the focal plane; and when the accumulated powder accumulates on the path of the optical cutting, it may even block the laser, affecting the cutting quality. In more serious cases, there will be safety hazards such as uncut tape and fire. In short, a large amount of dust or slag will accumulate near the cutting port, which will have a great impact on the stability, quality and machine production capacity of the pole piece cutting.
[0031] In order to clean the dust, it is usually necessary to shut down the machine and dismantle some mechanisms, but the shutdown operation will have a great impact on production capacity; not only that, the dust treatment at the laser cutting mouth requires trained professionals to perform the operation, manual cleaning will waste a lot of manpower and material resources, and the efficiency is also low. In addition, there are also uncontrollable factors during the operation that may cause damage to the electrode, which not only affects the subsequent cutting quality, but may also cause safety hazards.
[0032] First embodiment
[0033] Based on the above problems, the utility model provides a laser cutting device, which is applied to the lithium-ion battery production equipment industry, and is particularly suitable for laser die-cutting and slitting equipment.
[0034] See also Figure 1 The laser cutting device 10 includes a conveyor 100, a cutting chamber 200, a laser 300, a dust collecting part 400 and a scraper 500.
[0035] The conveyor 100 is used to convey the pole piece 20, the cutting chamber 200 is arranged on the conveying path of the conveyor 100, and the laser 300 is used to emit laser to cut the pole piece 20 located in the cutting chamber 200; the dust collecting piece 400 and the scraper 500 are both arranged in the cutting chamber 200, and the dust collecting piece 400 and the scraper 500 can move relatively, and the scraper 500 is used to scrape foreign matter from the dust collecting piece 400.
[0036] In this embodiment, the conveying path of the conveyor 100 is the movement path of the pole piece on the vertical plane as shown in the figure, so the conveyor 100 can drive the pole piece 20 to move in the vertical direction. During the startup of the conveyor 100, the laser 300 emits a high-power laser to act on the pole piece 20, thereby realizing the cutting process of the pole piece 20.
[0037] By setting up the dust collecting piece 400, the high-temperature dust particles generated in this process are attached to its surface. After accumulating to a certain extent, the scraper 500 scrapes off the dust particles and other foreign matter on the surface of the dust collecting piece 400, thereby realizing the dust cleaning operation; the cutting trajectory of the tab can be made as close to the cutting port as possible, ensuring the cutting stability and cutting quality; in addition, it also reduces the time and participation of manual operation, and improves the automation degree and production capacity of the machine.
[0038] It is understandable that the scraper 500 can be started in a timed manner so as to complete the cleaning operation without interrupting the cutting process, thereby ensuring production efficiency; of course, the scraping time and frequency can also be controlled manually, which is not specifically limited here.
[0039] Furthermore, the number of scrapers 500 can be set to be multiple, and the dust pieces 400 can be scraped simultaneously by multiple scrapers 500, thereby improving the scraping efficiency.
[0040] Furthermore, the laser cutting device 10 also includes a dust suction component 600 , which is disposed in the cutting chamber 200 and is used to absorb foreign matter from the dust receiving component 400 .
[0041] In this embodiment, after the scraper 500 removes dust particles and other foreign matter attached to the dust receiving part 400, the dust suction component 600 is started to clean up the dust particles and other foreign matter through the negative pressure generated by the dust suction component 600, so as to prevent the dust particles and other foreign matter scraped by the scraper 500 from floating to other structures and affecting the cutting operation.
[0042] In detail, the dust collecting assembly 600 is provided with a plurality of negative pressure holes, and foreign matters such as dust particles scraped off from the dust receiving component 400 are adsorbed through the plurality of negative pressure holes.
[0043] It should also be noted that, in addition to being used to absorb dust particles and improve cleaning efficiency, the dust suction component 600 can also be used to absorb the electrode 20, so that the electrode 20 located in the cutting area will be straightened during the transportation of the electrode 20, and the movement stability of the electrode 20 will be maintained, thereby improving the cutting stability and cutting quality of the electrode 20.
[0044] Furthermore, the dust collecting member 400 includes a first dust collecting plate 410 and a first driving member 420. The first driving member 420 is arranged in the cutting chamber 200. The first driving member 420 is connected to the first dust collecting plate 410 and is used to drive the first dust collecting plate 410 to move along the direction of the conveying path of the vertical conveyor 100.
[0045] In this embodiment, the first driving member 420 can be a driving device such as a cylinder or a motor, as long as it can drive the first dust collecting plate 410 to move in a direction perpendicular to the conveying path, and no specific limitation is made here.
[0046] By driving the first dust collecting plate 410 to move in the horizontal direction through the first driving member 420, the distance between the first dust collecting plate 410 and the pole piece 20 can be adjusted to meet different dust removal requirements and improve adaptability; the first dust collecting plate 410 can also be driven to move relative to the scraper 500 to achieve scraping operations.
[0047] Of course, in other embodiments, other driving members may also drive the scraper 500 to move relative to the first dust receiving plate 410 to achieve a scraping operation, which is not specifically limited here.
[0048] In detail, the first dust receiving plate 410 is disposed perpendicular to the conveying path of the conveyor 100 .
[0049] It can be understood that the vertically arranged first dust collecting plate 410 can make the dust particles generated during the cutting process more easily adhere to its surface.
[0050] Furthermore, the scraper 500 is made of metal material, and the dust collecting member 400 is made of non-metal material;
[0051] Alternatively, the scraper 500 is made of non-metallic material, and the dust collecting member 400 is made of metallic material.
[0052] In this embodiment, the scraper 500 and the first dust receiving plate 410 and the second dust receiving plate 430 can be made of non-metallic materials or metallic materials, but the scraper 500 and the first dust receiving plate 410 and the second dust receiving plate 430 are usually made of different types of materials, so as to avoid metal friction between the scraper 500 and the first dust receiving plate 410 or the second dust receiving plate 430, thereby avoiding reducing their service life.
[0053] Furthermore, the conveyor 100 includes a first roller 110 and a second roller 120 , which are used together to convey the pole piece 20 , and the dust collecting member 400 and the scraper 500 are located between the first roller 110 and the second roller 120 .
[0054] In this embodiment, the electrode piece 20 can be transported together by the first roller 110 and the second roller 120 . It can be understood that the path for transporting the electrode piece 20 between the first roller 110 and the second roller 120 is the transport path of the electrode piece 20 .
[0055] Furthermore, the laser cutting device 10 also includes a conveying component 800 , which is located on the conveying path of the conveyor 100 and is used to convey the pole piece 20 together with the conveyor 100 .
[0056] In this embodiment, the conveying assembly 800 is generally also composed of at least one roller, and the rotation speed of the roller of the conveying assembly 800 can be set to be greater than the rotation speed of the first roller 110 or the second roller 120, so that the electrode sheet 20 is straightened during the conveying process, thereby ensuring the stability of the cutting of the electrode sheet 20.
[0057] Second embodiment
[0058] See also Figure 2 The present utility model further provides a laser cutting device 10, which is different from the first embodiment in that the laser cutting device 10 further includes a second dust collecting plate 430 and a second driving member 440, and the second driving member 440 is used to drive the second dust collecting plate 430 to move in a direction parallel to the conveying path of the conveyor 100. For the sake of brief description, for matters not mentioned in this embodiment, please refer to the corresponding content in the first embodiment.
[0059] First of all, it should be noted that Figure 2 The viewing angle shown is the viewing angle of the laser 300. Figure 1 The structural schematic diagram of the laser cutting device 10 is regarded as a front view, then Figure 2 It can be regarded as a right side view of the laser cutting device 10 .
[0060] Furthermore, a second driving member 440 is disposed in the cutting chamber 200 , and the second driving member 440 is connected to the second dust collecting plate 430 , and is used to drive the second dust collecting plate 430 to move in a direction parallel to the conveying path of the conveyor 100 .
[0061] In this embodiment, the second driving member 440 can be a driving device such as a cylinder, a motor, etc., as long as it can drive the second dust collecting plate 430 to move in a direction parallel to the conveying path, and no specific limitation is made here.
[0062] It can be understood that the direction parallel to the conveying path of the conveyor 100 generally refers to movement in the horizontal direction along the plane where the pole piece 20 is located.
[0063] The second dust collecting plate 430 is driven by the second driving member 440 to move in a horizontal direction parallel to the plane where the pole piece 20 is located, so that the relative position of the second dust collecting plate 430 and other structural members can be adjusted, for example, the relative position of the second dust collecting plate 430 and the scraper 500, the conveying assembly 800, etc. can be adjusted.
[0064] Therefore, the position of the second dust collecting plate 430 can be adjusted according to different cutting conditions. For example, the second dust collecting plate 430 can be adjusted to cover the conveyor belt, thereby preventing the high-temperature dust generated at the cutting port from splashing onto the conveyor belt and seriously affecting the service life of the belt.
[0065] In detail, the second dust receiving plate 430 is disposed perpendicular to the conveying path of the conveyor 100 .
[0066] It can be understood that the vertically arranged second dust collecting plate 430 can make it easier for dust particles generated during the cutting process to adhere to its surface.
[0067] It should be noted that the first dust receiving plate 410 and the second dust receiving plate 430 can be provided at the same time, or only one of them can be provided, and can be adjusted according to actual needs, and no specific limitation is made here.
[0068] In summary, the utility model provides a laser cutting device 10, which arranges a dust collecting part 400 so that the high-temperature dust particles generated in the process adhere to its surface, and after accumulating to a certain extent, the scraper 500 scrapes off the dust particles and other foreign matter on the surface of the dust collecting part 400, thereby realizing the dust cleaning operation; the cutting trajectory of the tab can be made as close to the cutting port as possible, thereby ensuring the cutting stability and cutting quality; in addition, it also reduces the time and participation of manual operation, thereby improving the automation degree and production capacity of the machine.
