Description
Technical Field
[0001] The present application relates to the technical field of battery processing, and particularly to a roll cleaning device and a roll cleaning system thereof. Background Art
[0002] In the manufacturing process of the anode graphite electrode of a lithium-ion battery, roll pressing is a key process step. However, during the roll pressing process, the graphite material is prone to adhering to the roll surface, forming a phenomenon of graphite sticking to the roll.

Summary of the Utility Model
[0004] Based on this, it is necessary to provide a roll cleaning device and a roll cleaning system thereof that can effectively remove the graphite residue on the roll surface without introducing any solvent, ensure the roll surface is clean, and prevent graphite from sticking to the roll.

In the following description, numerous specific details are set forth to facilitate a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0032] In addition, the terms "first" and "second" are used only for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features.

[0034] Unless otherwise defined, all technical and scientific terms used in the specification of the present application have the same meaning as commonly understood by those skilled in the technical field to which the present application pertains. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used in the specification of the present application includes any and all combinations of one or more of the related listed items.
[0035] As Figures 1 to 3As shown in the figure, the present application provides a roll cleaning device 100, which is applied in the manufacturing process of the anode graphite electrode of a lithium-ion battery. Its function is to remove the graphite adhered to the surface of the roll (not shown in the figure) to avoid the phenomenon of graphite sticking to the roll surface.
[0036] Specifically, the roll cleaning device 100 includes a bracket 10 and a cleaning brush 20. The bracket 10 plays a supporting role. The cleaning brush 20 includes a fixing block 21 and a brush head layer 22. One side surface of the fixing block 21 is installed on the bracket 10, and the other side surface is arranged to face the roll. The brush head layer 22 is installed on the surface of the fixing block 21 facing the roll, and the brush head layer 22 is configured as a nano-foam layer. In this way, by utilizing the high density and antistatic characteristics of the nano-foam layer itself, it is ensured that the cleaning brush 20 can work stably for a long time, effectively remove the graphite residue on the roll surface and avoid secondary pollution caused by static electricity. At the same time, by rubbing the roll in the physical form of the nano-foam layer, the introduction of chemical solvents is avoided and the cost is reduced.
[0037] Please continue to refer to Figure 1 , the bracket 10 is in a long strip shape, and the number of cleaning brushes 20 is set to be multiple, and the multiple cleaning brushes 20 are arranged at intervals along the length direction of the bracket 10. In this way, it is possible to clean multiple positions on the roll surface simultaneously and improve the cleaning efficiency.
[0038] In an embodiment, as shown in Figure 1 and Figure 3 , the fixing block 21 is rotatably installed on the bracket 10 so that the fixing block 21 can rotate relative to the bracket 10 and adjust the angle. In this way, by setting the fixing block 21 to be able to rotate relative to the bracket 10 and adjust the angle, the movement of the fixing block 21 can drive the brush head layer 22 to change positions, so as to adapt to cleaning at different angles and positions, and further enable the cleaning brush 20 to meet the requirements of different roll pressing processes and ensure the stability of the roll rubbing effect.
[0039] Furthermore, the brush head layer 22 (i.e., the nano-foam layer) is installed on the side surface of the fixing block 21 by an adhesive bonding method. When the brush head layer 22 is cleaning, it needs to contact the roll surface. Even though the brush head layer 22 itself is made of wear-resistant materials, there will still be wear and it belongs to a consumable part. Therefore, it still needs to be replaced regularly to ensure the cleaning effect. By installing the brush head layer 22 by an adhesive bonding method, it can be quickly disassembled and installed, with a simple structure and higher replacement efficiency.
[0040] Of course, the connection method between the brush head layer 22 and the fixing block 21 is not limited to this. It can also be a magnetic attraction connection, a snap connection, etc., which will not be elaborated here again.
[0041] Preferably, the brush head layer 22 is configured as a three-dimensional network structure. With such a setting, when cleaning the graphite powder on the surface of the rolling mill roller, the three-dimensional network structure can automatically adsorb the graphite residue, reduce the dust falling and polluting the pole piece, and reduce the difficulty of dust collection. At the same time, the stability of the three-dimensional network structure effectively improves the overall structural strength of the brush head layer 22 and increases its wear resistance.
[0042] As Figures 1 to 3 shown, the roller cleaning device 100 further includes a driver 30 and a pressure detector 40. The driver 30 is connected to the bracket 10 and is used to drive the bracket 10 away from or close to the roller. The pressure detector 40 is installed on the bracket 10 and is signal-connected to the driver 30. The pressure detector 40 is used to detect the pressure exerted by the cleaning brush 20 on the roller and feedback it to the driver 30. With such a setting, the relative position adjustment between the cleaning brush 20 and the roller can be automatically realized through the cooperation of the pressure sensor and the driver 30, and the precise control of the pressure can be achieved, thereby improving the roller cleaning effect.
[0043] Here, the pressure detector 40 can be a pressure calibrator, a pressure measurer, a pressure tester, a pressure sensor, etc. In the embodiment of the present application, the pressure detector 40 is set as a pressure sensor to monitor the pressure between the two.
[0044] Furthermore, as Figure 1 shown, the roller cleaning device 100 further includes a moving mechanism 50. The moving mechanism 50 is connected to the driver 30, and the bracket 10 is connected to the moving mechanism 50, so that the bracket 10 can move away from or close to the roller under the drive of the driver 30 driving the moving mechanism 50.
[0045] Specifically, as Figures 1 to 3 shown, the moving mechanism 50 includes a first moving unit 51 and a second moving unit 52. The driver 30 includes a first driving element 31 and a second driving element 32. The first moving unit 51 is connected to the first driving element 31 and can move along the first direction X under the drive of the first driving element 31. The second moving unit 52 is installed on the first moving unit 51 and is connected to the second driving element 32 to move relative to the first moving unit 51 in the second direction Y under the drive of the second driving element 32. Wherein, the second direction Y is set at an angle to the first direction X, and the bracket 10 is installed on the second moving unit 52. Thus, the relative position adjustment between the cleaning brush 20 and the roller is realized by using the first moving unit 51 and the second moving unit 52.
[0046] Further, the first moving unit 51 includes a first moving seat 511 and a first guide rod 512. The first guide rod 512 is installed on the first moving seat 511 and extends along the first direction X. The first driving element 31 is installed on the first moving seat 511 and connected to the first guide rod 512. The second moving unit 52 is installed on the first guide rod 512. The first driving element 31 drives the first guide rod 512 to move, so that the second moving unit 52 slides on the first guide rod 512 as a whole.
[0047] Here, the first driving element 31 can be set as components such as a motor or a cylinder.
[0048] Exemplarily, the first driving element 31 can be set as a motor, and the first guide rod 512 can be configured as a screw rod. The second moving unit 52 is threadedly sleeved on the first guide rod 512. In this way, the motor moves and drives the first guide rod 512 to rotate. Thus, under the action of the screw pair, the second moving unit 52 moves on the first guide rod 512 as a whole.
[0049] Further, as Figure 2 shown, the first moving unit 51 further includes a first slider 513. The first slider 513 is threadedly sleeved on the first guide rod 512, and the second moving unit 52 is installed on the first slider 513. The motor drives the first guide rod 512 to rotate, and then makes the first slider 513 slide on the first guide rod 512, thereby driving the second moving unit 52 to move, that is, realizing the movement of the cleaning brush 20 in the first direction.
[0050] As Figures 1 to 3 shown, the second moving unit 52 includes a second moving seat 521 and a second guide rod 522. The second moving seat 521 is installed on the first guide rod 512, and the second guide rod 522 is installed on the second moving seat 521 and extends along the second direction Y. The second driving element 32 is installed on the second moving seat 521 and connected to the second guide rod 522. The bracket 10 is installed on the second guide rod 522. In this way, the second driving element 32 can be used to drive the second guide rod 522, so as to drive the bracket 10 to move in the second direction Y. At the same time, combined with the movement in the first direction X, the movement of the cleaning brush 20 in the first direction X and the second direction Y can be realized.
[0051] Here, the second driving element 32 can be set as components such as a motor or a cylinder.
[0052] Exemplarily, the second driving element 32 can be set as a motor, and the second guide rod 522 can be configured as a screw rod. The bracket 10 is threadedly sleeved on the first guide rod 512. In this way, the motor moves and drives the second guide rod 522 to rotate. Thus, under the action of the screw pair, the bracket 10 moves on the second guide rod 522 as a whole.
[0053] Further, as Figure 2As shown, the second moving unit 52 further includes a second slider 523. The second slider 523 is threadedly sleeved on the second guide rod 522, and the bracket 10 is mounted on the second slider 523. The motor drives the second guide rod 522 to rotate, thereby causing the second slider 523 to slide on the second guide rod 522, thus driving the bracket 10 to move, that is, realizing the movement of the cleaning brush 20 in the second direction Y.
[0054] The present application also provides a roll cleaning system. The roll cleaning system includes a dust collecting bin (not shown in the figure) and the roll cleaning device 100 in any of the above embodiments. Among them, along the vertical direction (i.e., the second direction Y), the dust collecting bin is relatively located below the cleaning brush 20. In this way, the dust collecting bin is used to collect the graphite powder to prevent the graphite powder from falling on the electrode sheet and causing pollution to the electrode sheet.
[0055] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0056] The above-described embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
