Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lithium ion battery production and processing equipment, in particular to a cleaning device, a dust removal assembly and a pole piece brush dust removal device. BACKGROUND

[0002] In the production process of lithium batteries, the winding process is a key process of battery forming. According to the process requirements of the battery cell, the positive pole piece, the negative pole piece and the separator are wound into a battery cell in turn after the steps of unwinding, deviation correction, tension control and pole piece cutting by the winding machine.

[0003] In the above process, the positive pole piece and the negative pole piece (hereinafter collectively referred to as the pole piece) are important raw materials in the winding process. The pole piece is centered on a metal foil, and the surfaces on both sides are coated with slurry. During the operation of the pole piece, it will be contaminated by particles of the environment or the slurry itself. The particles and dust will be wound into the battery cell, which will easily pierce the separator and cause short circuit and fire of the battery cell, causing immeasurable loss to the industry. Therefore, the pole piece brush dust removal device emerges as the times require and is an indispensable important mechanism of the winding machine.

[0004] The brush is made of nylon material. During the cleaning of the pole piece, some of the dust particles brushed off will remain on the surface of the brush and the brush cavity. If not cleaned in time, the dust particles remaining on the surface of the brush will cross-contaminate the subsequent pole piece. When the traditional brush device needs to be cleaned, personnel need to disassemble and install it, which requires a relatively long time. Moreover, the disassembly process is relatively complicated and requires professional maintenance personnel to disassemble, which is a waste of manpower and resources and affects the production time.

[0048] According to the first aspect of the present application, a cleaning device 1 is provided, which will be described below in combination with Figures 1 to 4 The structure and working principle of the cleaning device 1 will be described in detail.

[0049] According to the cleaning device 1 provided by the embodiments of the present application, the cleaning device 1 is used for cleaning a to-be-cleaned component 60, and the cleaning device 1 comprises a box body 50, a dust collecting member 10, a driving mechanism 20, and a disturbance mechanism 30.

[0050] In the embodiments, the box body 50 is provided with an inner cavity 55 for accommodating the to-be-cleaned component 60, the dust collecting member 10 is arranged on one side of the box body 50 along a first direction 80, and the dust collecting member 10 comprises a dust collecting main body 11, the dust collecting main body 11 has an accommodating portion 12 inside the dust collecting main body 11, and the accommodating portion 12 extends along the first direction 80.

[0051] In the embodiments, the dust collecting main body 11 further has a first opening 13 and an open structure 15, the first opening 13 is in communication with the accommodating portion 12, the first opening 13 is arranged on the side of the dust collecting main body 11 close to the box body 50, the open structure 15 is in communication with the first opening 13 and the accommodating portion 12, and the open structure 15 is located on the side of the dust collecting main body 11 along a second direction 90, the second direction 90 being perpendicular to the first direction 80.

[0052] In the embodiments, the driving mechanism 20 is connected with the dust collecting member 10, the driving mechanism 20 drives the dust collecting member 10 to move along the first direction 80 and into the inner cavity 55, so that the to-be-cleaned component 60 enters the accommodating portion 12. In the embodiments, the disturbance mechanism 30 is arranged in the box body 50, when the dust collecting member 10 enters the inner cavity 55, the disturbance mechanism 30 can move towards the open structure 15 and at least partially pass through the open structure 15 to enter the accommodating portion 12, and the disturbance mechanism 30 is used for providing the to-be-cleaned component 60 with gas disturbance and / or contact disturbance.

[0053] In this way, according to the cleaning device 1 provided by the embodiments of the present application, the disturbance mechanism 30 can be used to apply gas disturbance and / or contact disturbance to the to-be-cleaned component 60, so as to remove the dust particles and other impurities on the to-be-cleaned component 60 from the to-be-cleaned component 60. While the to-be-cleaned component 60 is being cleaned, the dust removed from the to-be-cleaned component 60 can also be collected by the dust collecting member 10.

[0054] Specifically, the driving mechanism 20 is capable of driving the dust collecting member 10 to the outside of the component to be cleaned 60, so that the component to be cleaned 60 enters into the accommodating portion 12 of the dust collecting member 10, thereby collecting the dust particles removed from the component to be cleaned 60. Thus, according to the cleaning device 1 provided by the embodiments of the present application, after the component to be cleaned 60 is cleaned, the dust particles removed are collected by the dust collecting member 10, on the one hand, without the need of replacing the component to be cleaned 60, reducing the time consumed by dismounting and mounting, saving manpower and material resources, shortening the production time, and also being capable of avoiding the re-pollution of the dust particles to the surrounding components and structures.

[0055] In embodiments, the component to be cleaned 60 can be, for example, a brush, which can be used for cleaning the pole piece 2, for example. Thus, according to the cleaning device 1 provided by the embodiments of the present application, the dirty brush does not need to be dismounted and mounted by personnel, but is directly cleaned in the dust collecting member 10, thus greatly saving the production time.

[0056] In embodiments, as an example, the dust collecting member 10 can be, for example, a cuboid-shaped housing structure, that is, the dust collecting body 11 can be, for example, a cuboid-shaped housing structure. In embodiments, the dust collecting body 11 can have a first opening in the first direction 80, which can be, for example, the length direction of the dust collecting body 11. In addition to the above-mentioned first opening, the dust collecting body 11 can also have a second opening 14 opposite to the second opening 14 in the length direction, which will be described in detail later.

[0057] In embodiments, the component to be cleaned 60 is arranged in the inner cavity 55 of the box body 50. As an example, when the component to be cleaned 60 is a brush, the brush can be rotatably arranged in the box body 50. As shown in FIG. 1, the box body 50 can also be, for example, a cuboid-shaped structure, and the length direction thereof is the same as that of the dust collecting member 10. Figure 3 In embodiments, the brush can be rotatably arranged on at least one side wall of the box body 50 in the length direction, or between two side walls of the box body 50 in the length direction.

[0058] In embodiments, the box body 50 can have one side wall in the length direction, which can be arranged away from the dust collecting member 10, and a motor 70 can be arranged outside the side wall, the shaft of the motor 70 can pass through the side wall to be rotatably connected with the brush, and a bearing can also be arranged between the shaft of the motor 70 and the hole of the side wall for the shaft to pass through, for example. On the opposite side of the side wall, the box body 50 can be completely open, so that the dust collecting member 10 moves along the length direction to enter into the inner cavity 55 of the box body 50.

[0059] In other examples, the box 50 can have two side walls in the length direction, and the two ends of the brush can be rotatably connected to the two side walls respectively through shafts and bearings. As shown in Figure 3 Figure 3 The example shown is just this, in which a through portion 51 is provided on the side wall close to the dust collecting member 10, the through portion 51 is a through hole penetrating the side wall, which is substantially the same in shape as the cross section of the dust collecting member 10, so as to allow the dust collecting member 10 to pass through and enter the inner cavity 55 of the box 50.

[0060] In the embodiments, the meaning of the gas disturbance applied by the disturbance mechanism 30 should be understood as including blowing the brush using a gas flow, and the meaning of the contact disturbance applied by the disturbance mechanism 30 should be understood as applying a contact disturbance to the brush, and the purpose of both disturbance forms is to make the dust particles adhered to the brush fall off from the brush to clean the brush.

[0061] In the embodiments, the dust collecting member 10 can be driven by a linear driving structure connected to the dust collecting member 10, such as a pneumatic cylinder or an electric cylinder, which can be arranged outside the box 50 and spaced apart from the box 50, or as shown in the Figure 1 embodiments of the present application, connected to the box 50, for example, the upper side of the box 50. This will be described in the subsequent description.

[0062] According to the cleaning device 1 provided by the embodiments of the present application, the open structure 15 can include a gas open portion 16 and a contact open portion 17, and when the dust collecting member 10 enters the inner cavity 55, the disturbance mechanism 30 can pass through the gas open portion 16 and the contact open portion 17 to enter the containing portion 12, so as to be able to clean the brush correspondingly.

[0063] According to the cleaning device 1 provided by the embodiments of the present application, on the basis of the above gas open portion and contact open portion 17, the disturbance mechanism 30 includes a gas spraying member 32 and a contact member 33, the gas spraying member 32 is used for spraying gas, and the contact member 33 is configured to be able to have relative motion with the component to be cleaned 60, and when the dust collecting member 10 enters the inner cavity 55, the gas spraying member 32 and the contact member 33 pass through the open structure 15 to enter the containing portion 12. Here, as an example, the gas spraying member 32 can enter the containing portion 12 from the gas open portion, and the contact member 33 can enter the containing portion 12 from the contact open portion 17.

[0064] In the embodiments, the gas open portion 16 and the contact open portion 17 can both penetrate the inner wall of the dust collecting body 11, so as to communicate with the containing portion 12 in the dust collecting body 11, that is, to communicate the containing portion 12 with the environment outside the dust collecting body 11.

[0065] ​According to the cleaning device 1 provided in the embodiments of this application, as described above, the open structure 15 includes the gas opening portion 16 and the contact opening portion 17 as described above. The contact opening portion 17 can extend along the first direction 80 and can communicate with the first opening 13.

[0066] As an example, in this embodiment, the contact opening 17 may extend along the length direction and is disposed on one side of the dust collection body 11 in the second direction 90. Here, the second direction 90 may be, for example, the width direction of the dust collection body 11 and the housing 50. Both ends of the contact opening 17 in the length direction may be open, for example, the contact opening 17 may be rectangular in shape, and its two ends in the length direction are respectively connected to the first opening and the second opening 14 as described above.

[0067] In this embodiment, there can be multiple gas openings 16, which can be distributed on both sides of the contact opening 17. As an example, the gas openings can be through holes, which can be divided into two groups, located on both sides of the contact opening 17, for example, on the upper and lower sides of the contact opening 17 respectively. This achieves a relatively uniform distribution of the through holes, thereby ensuring uniform cleaning of the brush. In this embodiment, the number of through holes in the upper and lower groups can be the same, for example, three in each group, and the three through holes in each group can be arranged sequentially at intervals along the length direction.

[0068] In this embodiment, the disturbance mechanism 30 includes a jetting component 32 and a contacting component 33. When the dust collection component 10 enters the inner cavity 55, the jetting component 32 and the contacting component 33 pass through the gas opening portion 16 and the contact opening portion 17 respectively and enter the receiving portion 12.

[0069] like Figure 2 As shown, in this embodiment, the jetting component 32 can be, for example, a gas nozzle, and the contacting component 33 can be, for example, a strip-shaped brush structure. The contacting component 33 can extend along the length direction as described above, and it has a strip-shaped main body structure and a protruding structure protruding outward from the main body structure. The protruding structure is used to insert into the brush. When the brush rotates under the drive of the motor 70, the contacting component 33 can provide a contact-type disturbance to the brush by making direct contact with the brush, thereby removing dust particles and providing a better cleaning effect.

[0070] According to the cleaning device 1 provided in the embodiments of the present application, the disturbing mechanism 30 further comprises a mounting member 31, which can be a mounting plate for example, and the jetting members 32 and the contact members 33 can be mounted on the mounting member 31. In the embodiments, the mounting plate can be located inside the box body 50, and the jetting members 32 can be fixed on the mounting plate, each of the jetting members 32 has a corresponding gas supply pipe and a head portion in communication with the gas supply pipe, the head portion can be arranged on the side of the mounting plate facing the brush, and the gas supply pipe can be arranged on the side of the mounting plate facing away from the brush, and the gas supply pipe further penetrates through the side wall of the box body 50 in the width direction (i.e. the second direction 90) so as to extend to the outside of the box body 50.

[0071] In the embodiments, the gas supply pipe can be in communication with an external gas pipeline, the external gas pipeline can be connected to a gas source such as a gas cylinder, and a valve such as an electromagnetic valve can be arranged on the external gas pipeline, by controlling the opening and closing of the valve, the gas can flow to the head portion of the jetting member 32 and be sprayed towards the brush via the head portion to form gas disturbance to the brush, so as to clean the brush.

[0072] In the embodiments, the cleaning device 1 can further comprise a driving assembly 40, the driving assembly 40 can be connected with the mounting member 31, and the driving assembly 40 drives the mounting member 31 to move towards the open structure 15. In the embodiments, the driving assembly 40 can be a pneumatic cylinder for example, which can be connected to the outside of the box body 50, and the piston rod of the pneumatic cylinder can penetrate through the outside plate of the box body 50 and be connected to the mounting plate, so that the pneumatic cylinder can drive the mounting member 31 to move in the width direction, after the dust collecting member 10 moves to the position in the inner cavity 55 of the box body 50, the pneumatic cylinder drives the jetting members 32 and the contact members 33 to move into the containing portion 12 of the dust collecting member 10 to clean the brush, and after the brush is cleaned, the pneumatic cylinder drives the jetting members 32 and the contact members 33 to exit so as to allow the dust collecting member 10 to leave the inner cavity 55 of the box body 50.

[0073] In this way, the reciprocating driving mode of the pneumatic cylinder is used to make the jetting members 32 and the contact members 33 avoid the dust collecting member 10, and ensure that the dust collecting member 10 can reciprocate.

[0074] According to the cleaning device 1 provided in the embodiments of the present application, the driving mechanism 20 comprises a driving member 21 arranged on the box body 50 and a guide member 22 arranged on the inner side of the box body 50, the guide member 22 can extend along the first direction 80, and the dust collecting member 10 is in sliding connection with the guide member 22 and is configured to be driven by the driving member 21 to move into the inside of the box body 50 along the guide member 22.
