Abstract

The utility model provides a dust removal device and a cutting and stacking all-in-one machine. The dust removal device comprises a conveying mechanism, a first blowing dust removal mechanism and a first hollow isolation mechanism, and the conveying mechanism is used for conveying materials; the first blowing dust removal mechanism is provided with a first dust removal surface located on one side of a material conveying path. The first hollowed-out isolation mechanism is located on the side, close to the materials, of the first dust removal surface so that the first hollowed-out isolation mechanism can be located between the first dust removal surface and the materials. Due to the fact that the first hollowed-out isolation mechanism is located between the first dust removal surface and the materials, even if the materials deform due to the influence of airflow, the first dust removal surface can be prevented from making direct contact with the materials, and therefore the material damage problem that the materials are collided and / or scratched by the first blowing dust removal mechanism can be avoided.

[0002] There are two main methods for dust removal on the surface of strip-shaped or independent sheet materials such as lithium battery pole pieces: contact dust removal (such as using a brush to remove dust) and non-contact dust removal (such as using an air knife to blow away dust). It is generally believed that non-contact dust removal can better protect materials and avoid material damage than contact dust removal, but in actual applications, it is found that during dust removal by blowing, the material will be deformed by the airflow, and then the material will be damaged by the dust removal mechanism, such as being hit and / or scratched. Utility Model Content

[0026] like Figure 1-Figure 3 As shown, a dust removal device 10 provided in one embodiment of the utility model comprises a conveying mechanism 300 , a first purge dust removal mechanism 400 and a first hollow isolation mechanism 500 .

[0027] The conveying mechanism 300 is used to convey the material 20. The first blowing and dust removal mechanism 400 has a first dust removal surface 410 located on one side of the conveying path of the material 20, that is, the first blowing and dust removal mechanism 400 has a first dust removal surface 410 located next to the conveying path of the material 20. The first hollow isolation mechanism 500 is located on the side of the first dust removal surface 410 close to the material 20, so that the first hollow isolation mechanism 500 can be located between the first dust removal surface 410 and the material 20.

[0028] In the above dust removal device 10, when the conveying mechanism 300 conveys the material 20 to the first dust removal surface 410 facing the first purge dust removal mechanism 400, the dust removal airflow blown out of the first dust removal surface 410 passes through the first hollow isolation mechanism 500 and acts on the material 20, thereby achieving purge dust removal of the material 20. At the same time, since the first hollow isolation mechanism 500 is located between the first dust removal surface 410 and the material 20, even if the material 20 is deformed by the airflow, the first dust removal surface 410 can be prevented from directly contacting the material 20, thereby preventing the material 20 from being damaged by the first purge dust removal mechanism 400 and / or scratched.

[0029] In this embodiment, the first dust removal surface 410 has both a blowing port and a suction port. The blowing port is used to blow out dust removal airflow to the material 20. The suction port is used to suck away the dust on the material 20. The blowing port and the suction port work together to achieve the blowing and dust removal of the material 20. In this way, not only a better dust removal effect is achieved, but also dust can be prevented from being scattered to various places of the dust removal device 10. It can be understood that in other embodiments, the first dust removal surface 410 can also have only a blowing port, and the dust on the material 20 is removed by the impact force of the airflow.

[0030] It should be noted that when a dust removal device having both a blowing port and a suction port on its dust removal surface is working, the material may be folded by the blowing port on the dust removal surface, causing the material to wrinkle and deform; the material may also be adsorbed by the suction port on the dust removal surface, causing the material to stagnate (cannot continue to be transported along the conveying path), causing the material to wrinkle and deform, which may lead to material damage problems such as the material being hit and / or scratched by the dust removal mechanism.

[0031] In the present embodiment, the first dust removal surface 410 has a first air suction port, an air blowing port, and a second air suction port. The first air suction port, the air blowing port, and the second air suction port are arranged in sequence on the conveying path of the material 20. In this way, the dust on the material 20 with less adhesion to the material 20 (that is, the dust with greater looseness) can be first sucked away by the first air suction port, and the dust on the material 20 with greater adhesion to the material 20 (that is, the dust with less looseness) can first be shaken by the air blowing port to become dust with less adhesion to the material 20 (that is, the dust with greater looseness) and then be sucked away by the second air suction port. Therefore, the above-mentioned dust removal device 10 has a better dust removal effect. It can be understood that in other embodiments, the first dust removal surface 410 may also have only one of the first air suction port and the second air suction port and the air blowing port.

[0032] In this embodiment, the first purge dust removal mechanism 400 is an ultrasonic dust removal head. In this way, by using ultrasonic dust removal, the dust removal device 10 can have a better dust removal effect. It can be understood that in other embodiments, the first purge dust removal mechanism 400 can also be a device that can spray high-pressure airflow. Specifically, in this embodiment, the first dust removal surface 410 can be a contoured arc surface or a plane.

[0033] In the present embodiment, the conveying mechanism 300 includes a conveying belt 310 for conveying the material 20. The first hollow isolation mechanism 500 is a part of the conveying belt 310. In this way, not only can the structure of the dust removal device 10 be simplified, but also the first hollow isolation mechanism 500 and the material 20 have the same forward direction and speed, which can prevent the material 20 from moving and contacting the first hollow isolation mechanism 500 and causing damage. It can be understood that in other embodiments, the first hollow isolation mechanism 500 can also be independent of the conveying belt 310. For example, the first hollow isolation mechanism 500 is located on the side of the conveying belt 310 away from the material 20, and the first dust removal surface 410 is located on the side of the first hollow isolation mechanism 500 away from the material 20.

[0034] In the present embodiment, the conveying mechanism 300 further includes a plurality of conveying rollers 320. The conveying conveyor belt 310 is in a closed loop structure. A plurality of conveying rollers 320 are distributed inside and outside the closed loop structure to support the conveying conveyor belt 310. The first blowing and dust removal mechanism 400 is located in the closed loop structure and between two adjacent conveying rollers 320 (at this time, there is no conveying roller 320 between the first blowing and dust removal mechanism 400 and the first hollow isolation mechanism 500). In this way, the conveying roller 320 can be prevented from blocking the first dust removal surface 410, which is not only conducive to the dust removal airflow acting on the material 20, but also convenient for adjusting the distance between the first dust removal surface 410 and the first hollow isolation mechanism 500. It can be understood that in other embodiments, there may also be a conveying roller 320 between the first blowing and dust removal mechanism 400 and the first hollow isolation mechanism 500.

[0035] Specifically, in the present embodiment, the conveying conveyor belt 310 is a belt. The plurality of conveying rollers 320 include four inner conveying rollers located inside the conveying conveyor belt 310 and two outer conveying rollers located outside the conveying conveyor belt 310. The four inner conveying rollers include two main driving rollers 322a, one belt passing roller 322b and one belt driving roller 322c. The two main driving rollers 322a are arranged at intervals on the conveying path of the material 20, one belt passing roller 322b and one belt driving roller 322c are arranged at intervals in a direction parallel to the conveying path of the material 20, and the two main driving rollers 322a are closer to the material 20 than one belt passing roller 322b and one belt driving roller 322c. On the conveying path of the material 20, the belt passing roller 322b is arranged opposite to the main driving roller 322a located upstream, and the belt driving roller 322c is located downstream of the main driving roller 322a located downstream. The two outer conveying rollers include a belt tensioning roller 324a located between the belt passing roller 322b and the belt driving roller 322c and a belt passing roller 324b located between the belt driving roller 322c and the main driving roller 322a. The first purging and dust removal mechanism 400 is located between the two main driving rollers 322a.

[0036] In the present embodiment, the first hollow isolation mechanism 500 is a grid mechanism, that is, the conveyor belt 310 is a grid belt. In this way, it is easier to manufacture the first hollow isolation mechanism 500. It can be understood that in other embodiments, the hollow pattern on the first hollow isolation mechanism 500 is not limited to a grid shape, but can be any shape. In the present embodiment, the material of the first hollow isolation mechanism 500 can be Teflon, polyurethane (PU), polyvinyl chloride (PVC), polyethylene (PE), rubber, etc.

[0037] In this embodiment, the dust removal device 10 further includes a second blowing and dust removal mechanism 600, which has a second dust removal surface 610 located on the other side of the conveying path of the material 20, that is, the second blowing and dust removal mechanism 600 has a second dust removal surface 610 located next to the conveying path of the material 20. The first dust removal surface 410 and the second dust removal surface 610 are arranged opposite to each other and form a dust removal gap for the material 20 to pass through between the first dust removal surface 410 and the second dust removal surface 610. The first dust removal surface 410 and the second dust removal surface 610 can remove dust from the two surfaces of the material 20 respectively to achieve double-sided dust removal, thereby avoiding the material 20 from having to pass through at least two dust removal stations to achieve double-sided dust removal, thereby avoiding secondary contamination of the material 20. It can be understood that in other embodiments, the second blowing and dust removal mechanism 600 can be omitted, and in this case, the first dust removal surface 410 can be used to remove dust from one side of the material 20 first, and then the first dust removal surface 410 can be used to remove dust from the other side of the material 20.

[0038] In this embodiment, the structure of the second blowing and dust removal mechanism 600 is the same as that of the first blowing and dust removal mechanism 400, and will not be repeated here.

[0039] In this embodiment, the dust removal device 10 further includes a second hollow isolation mechanism 700. The second hollow isolation mechanism 700 is located on the side of the second dust removal surface 610 close to the material 20, so that the second hollow isolation mechanism 700 can be located between the second dust removal surface 610 and the material 20. In the above dust removal device 10, when the conveying mechanism 300 conveys the material 20 to the second dust removal surface 610 facing the second purge dust removal mechanism 600, the dust removal airflow blown out of the second dust removal surface 610 passes through the second hollow isolation mechanism 700 and acts on the material 20, thereby achieving purge dust removal of the material 20. At the same time, since the second hollow isolation mechanism 700 is located between the second dust removal surface 610 and the material 20, even if the material 20 is deformed by the airflow, the second dust removal surface 610 can be prevented from directly contacting the material 20, thereby avoiding the problem of damage to the material 20 such as the material 20 being hit and / or scratched by the second purge dust removal mechanism 700.

[0040] In this embodiment, the first dust removal surface 410 and the second dust removal surface 610 are arranged opposite to each other. In this way, the dust removal device 10 can have a smaller size on the conveying path of the material 20. It can be understood that in other embodiments, the first dust removal surface 410 can also be upstream of the conveying path of the material 20 relative to the second dust removal surface 610, or vice versa, the first dust removal surface 410 can also be downstream of the conveying path of the material 20 relative to the second dust removal surface 610.

[0041] In this embodiment, the distance between the first dust removal surface 410 and the second dust removal surface 610 can be adjusted to adjust the size of the dust removal gap. In this way, the dust removal device 10 can be adapted to materials 20 of different sizes and dust materials 20 of different sizes can be removed. It is understood that in other embodiments, the distance between the first dust removal surface 410 and the second dust removal surface 610 can also be fixed.

[0042] In this embodiment, the dust removal device 10 further includes a limiting mechanism 800 arranged opposite to the conveying mechanism 300. The limiting mechanism 800 is used to limit the side of the material 20 away from the first hollow isolation mechanism 500 to prevent the material 20 from moving toward the side away from the first hollow isolation mechanism 500. In this way, the limiting mechanism 800 and the conveying mechanism 300 can be used together to ensure that the material 20 is transported smoothly, so that it is very convenient to simultaneously transport the material 20 by the conveying mechanism 300 and to blow and dust the material 20 by the first purge and dust removal mechanism 400. It can be understood that in other embodiments, a negative pressure mechanism can be provided on the conveying mechanism 300, and the negative pressure can be used to stably adsorb the material 20 on the conveying mechanism 300, so that the material 20 can be transported smoothly. At this time, the first hollow isolation mechanism 500 can be located on the side of the conveying belt 310 away from the material 20, and the first dust removal surface 410 is located on the side of the first hollow isolation mechanism 500 away from the material 20.

[0043] In this embodiment, the limiting mechanism 800 can elastically (floatingly) abut against the material 20. Thus, the limiting mechanism 800 can press the material 20, so that the material 20 is smoothly conveyed without crushing the material 20. It can be understood that in other embodiments, the limiting mechanism 800 can also be spaced from the material 20.

[0044] In this embodiment, the limiting mechanism 800 includes a limiting conveyor belt 810 for contacting the side of the material 20 away from the first hollow isolation mechanism 500. The second hollow isolation mechanism 700 is a part of the limiting conveyor belt 810. In this way, not only can the structure of the dust removal device 10 be simplified, but also the material 20 can be more smoothly transported. It can be understood that in other embodiments, the second hollow isolation mechanism 700 can also be independent of the limiting mechanism 800. For example, the limiting mechanism 800 includes two limiting blocks for contacting the material 20, and the second hollow isolation mechanism 700 and the second purge dust removal mechanism 600 are arranged between the two limiting blocks.

[0045] In the present embodiment, the limiting mechanism 800 further includes a plurality of limiting rollers 820. The limiting conveyor belt 810 is a closed loop structure. A plurality of limiting rollers 820 are distributed inside and outside the closed loop structure to support the limiting conveyor belt 810. The second blowing and dust removal mechanism 600 is located inside the limiting conveyor belt 810 and between two adjacent limiting rollers 820. In this way, the limiting roller 820 can be prevented from blocking the second dust removal surface 610, which is not only beneficial for the dust removal airflow to act on the material 20, but also convenient for adjusting the distance between the second dust removal surface 610 and the second hollow isolation mechanism 700. It can be understood that in other embodiments, a limiting roller 820 may also be provided between the second blowing and dust removal mechanism 600 and the second hollow isolation mechanism 700.

[0046] Specifically, in the present embodiment, the limiting conveyor belt 810 is a belt. The plurality of limiting rollers 820 include four inner limiting rollers located inside the limiting conveyor belt 810 and two outer limiting rollers located outside the limiting conveyor belt 810. The four inner limiting rollers include two follower pressure rollers 822a, one belt passing roller 822b and one belt driving roller 822c. The two follower pressure rollers 822a are arranged at intervals on the conveying path of the material 20, one belt passing roller 822b and one belt driving roller 822c are arranged at intervals in a direction parallel to the conveying path of the material 20, and the two follower pressure rollers 822a are closer to the material 20 than one belt passing roller 822b and one belt driving roller 822c. On the conveying path of the material 20, the belt passing roller 822b is arranged opposite to the follower pressure roller 822a located upstream, and the belt driving roller 822c is located downstream of the follower pressure roller 822a located downstream. The two outer limiting rollers include a belt tensioning roller 824a located between the belt passing roller 822b and the belt driving roller 822c and a belt passing roller 824b located between the belt driving roller 822c and the follower pressure roller 822a. The second blowing and dust removal mechanism 600 is located between the two follower pressure rollers 822a.

[0047] In this embodiment, the structure of the second hollow isolation mechanism 700 is the same as that of the first hollow isolation mechanism 500, and a repeated description thereof will not be given here.

[0048] In this embodiment, the dust removal device 10 further includes a reference plate 900 . The conveying mechanism 300 , the first blowing and dust removal mechanism 400 , the first hollow isolation mechanism 500 , the second blowing and dust removal mechanism 600 , the second hollow isolation mechanism 700 and the limiting mechanism 800 are all arranged on the reference plate 900 .

[0049] Specifically, in this embodiment, the two follower pressure rollers 822a are both wrapped with an elastic outer layer. In this way, the limiting conveyor belt 810 and the elastic outer layer can constitute an elastic pressure member, so that the limiting mechanism 800 can elastically abut against the material 20. Among them, the elastic outer layer can be a rubber layer. It can be understood that in other embodiments, the two follower pressure rollers 822a can also be connected to the reference plate 900 through elastic members respectively. In this way, the elastic member, the follower pressure roller 822a and the limiting conveyor belt 810 can constitute an elastic pressure member, so that the limiting mechanism 800 can elastically abut against the material 20.

[0050] Specifically, in the present embodiment, at least one of the belt roller 322b, the belt roller 324b, the belt roller 822b, and the belt roller 824b is rotatably connected to the reference plate 900. In this way, the dust removal device 10 can have a smaller volume. Because, compared with the arrangement in which all the rollers are fixed, the arrangement in which at least one roller can rotate is more conducive to belt transmission, thereby reducing the number of driving rollers that need to be driven by the driving mechanism, and further the dust removal device 10 can have a smaller volume.

[0051] The utility model also provides a cutting and laminating machine. The cutting and laminating machine includes the above-mentioned dust removal device 10. That is, in this embodiment, the material 20 is a lithium battery pole piece in a strip shape or an independent sheet shape. It can be understood that in other embodiments, the above-mentioned dust removal device 10 can also be applied to other equipment. In this case, the material 20 can be various types of materials 20 in a strip shape or an independent sheet shape, for example, the material 20 can be an optical sheet.

[0052] The above description is only an optional embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
