[0001] The present application relates to the technical field of production equipment, and in particular to a coating roller cleaning device, a battery coating device and a battery production line. Background Art

[0002] A coating device and a coating roller cleaning device are required in the production process of batteries, etc. The coating roller cleaning device uses a scraper to clean the excess slurry on the coating roller. In the related technology, the scraper will change its angle with the coating roller during the feeding process, thereby affecting the uniformity of cleaning. Utility Model Content

[0003] In order to solve the above technical problems, the purpose of this application is to provide a coating roller cleaning device, battery coating equipment and battery production line.

[0004] The first aspect of the present application provides a coating roller cleaning device, comprising a carrier, a first scraper and a first driving member, wherein the carrier can move to a working position relative to the coating roller, and the first scraper is used to clean the slurry on the circumferential surface of the coating roller; the first driving member is connected to the carrier, and the first driving member includes a first output part for linear motion, and the first output part is connected to the first scraper. When the carrier is in the working position, the first output part drives the first scraper to move along a linear path toward or away from the coating roller, so that a preset gap is maintained between the first scraper and the circumferential surface; the first driving member is an elastic member, and the elastic member can at least provide a preset elastic force along the linear path to drive the first scraper to maintain a preset gap; or, the first driving member is a telescopic cylinder, and the telescopic cylinder is configured with a preset pressure to drive the first scraper to maintain a preset gap.

[0005] In the technical solution provided in the embodiment of the present application, the carrier provides an installation base for the first drive member and the first scraper, the first scraper can be used to clean the slurry on the circumferential surface of the coating roller, so that the slurry is evenly attached to the circumferential surface of the coating roller, and the first drive member is used to drive the first scraper to move to maintain a preset gap between the first scraper and the circumferential surface of the coating roller. On this basis, the first drive member includes a first output portion, the first output portion moves linearly, and the first scraper is connected to the first output portion, so that the first drive member drives the first scraper to move along a linear path, and then toward or away from the coating roller. Since the first scraper moves linearly, the relative angle with the coating roller remains unchanged during the feeding process, reducing the uneven wear of the scraper, so that the first scraper and the circumferential surface of the coating roller can maintain a uniform interval to improve the uniformity of the slurry on the circumferential surface of the coating roller. In addition, since the first scraper moves linearly, the space occupied during the movement is small, which is also convenient for its layout in a small space and is conducive to the miniaturization of the coating roller cleaning device. Compared with the solution in the related art that the scraper is fed by rotating, the coating roller cleaning device of the embodiment of the present application drives the first scraper to feed linearly through the first driving member, which can improve the uniformity of scraper wear, thereby maintaining the uniformity of the first scraper cleaning the coating roller, and is conducive to space saving and miniaturization of the equipment. In addition, the use of an elastic member as the first driving member is simple in structure and easy to assemble; the use of a telescopic cylinder as the first driving member can provide a stable pressing force to keep the first scraper working smoothly.

[0006] In some embodiments of the present application, the coating roller cleaning device includes a connecting assembly, the connecting assembly includes a first slider, the first slider is slidably connected to the supporting frame along the movement direction of the first output part, and the first scraper is connected to the first slider.

[0007] Here, a first slider is provided to slidably connect the first scraper to the supporting frame. On the one hand, it can be used to correct the feeding direction of the first scraper and improve the movement stability of the first scraper. On the other hand, the supporting frame can provide support for the first scraper to keep the first scraper stable during the scraping process.

[0008] In some embodiments of the present application, the coating roller cleaning device further includes an adapter, which is disposed between the first scraper and the first output portion, and is movably disposed along a direction perpendicular to the straight line path.

[0009] Here, by arranging an adapter between the first scraper and the first output portion, the adapter can be movable to compensate for the assembly error between the two, thereby facilitating the assembly of the first scraper and the first output portion.

[0010] In some embodiments of the present application, the coating roller cleaning device also includes a second driving member and at least two second scrapers; the at least two second scrapers are respectively arranged on both sides of the first scraper along a preset direction, and the second scraper is used to clean the slurry on the radial surface of the coating roller; the second driving member is slidably connected to the supporting frame along a preset direction, and the second driving member includes at least two second output parts that move along the preset direction, and the at least two second output parts are connected to at least two second scrapers in a one-to-one correspondence to drive the second scrapers on both sides of the first scraper to move closer to or away from each other; wherein the preset direction is perpendicular to the straight path.

[0011] Here, the second driving member can respectively drive at least two second scrapers to move relative to each other in a preset direction, and the second driving member is slidably connected to the supporting member. When one of the second scrapers contacts the coating roller and the other does not, due to the unbalanced force on the second driving member in the preset direction, the force will drive the second driving member to slide relative to the supporting member until both second scrapers effectively contact the coating roller, that is, the two second scrapers are aligned relative to the coating roller.

[0012] In some embodiments of the present application, the coating roller cleaning device further includes an adjusting structure, which is disposed between the second scraper and the supporting frame, and is used to adjust the distance between the second scraper and the first scraper.

[0013] Here, the distance between the second scraper and the first scraper can be changed by adjusting the structure. When disassembly and assembly are required, the distance can be increased to facilitate disassembly and assembly; when the coating roller needs to be cleaned, the distance can be reduced to maintain close contact between the first scraper and the second scraper. The surface of the coating roller can be fully cleaned, cleaning dead corners can be eliminated, and the cleaning effect can be improved.

[0014] In some embodiments of the present application, the coating roller cleaning device also includes a retaining member, which is provided with a slot, and the slot is adapted to be snap-fitted with the corresponding scraper, and the scraper is connected to the corresponding driving member through the retaining member; wherein the scraper includes at least a first scraper, and the driving member includes at least a first driving member.

[0015] Here, by providing a retainer, a slot is provided on the retainer, and the scraper is clamped in the slot, which is convenient for disassembly and assembly. In addition, since the slot can limit the scraper in multiple directions, the two can also maintain a large contact area, thereby improving the connection stability of the scraper.

[0016] In some embodiments of the present application, a guide portion is further provided on a side of the retaining member away from the corresponding driving member, and the guide portion is used to guide the slurry to flow away from the corresponding driving member.

[0017] Here, since a guide portion is provided on the side of the retaining member away from the driving member, the slurry is guided to flow away from the driving member, reducing the possibility of the slurry flowing toward the driving member, thereby weakening the adverse effect of the slurry on the driving member, which is beneficial to improving the service life of the driving member.

[0018] In some embodiments of the present application, the coating roller cleaning device also includes a protective member, which is arranged between the corresponding scraper and the driving member and is relatively fixed to the corresponding driving member; wherein the scraper includes at least a first scraper, and the driving member includes at least a first driving member.

[0019] Here, by providing a protective member disposed between the scraper and the driving member, the splashing slurry can be prevented from contacting the driving member, thereby weakening the adverse effect of the slurry on the driving member, which is beneficial to improving the service life of the driving member.

[0020] In some embodiments of the present application, the coating roller cleaning device further comprises a base, the support frame comprises a rotating portion, the rotating portion is rotatably connected to the base, and the support frame can be moved to a working position and an assembly position away from the coating roller through the rotating portion.

[0047] Below, this application is described in detail.

[0048] The coating device is required in the production process of batteries, etc. The coating roller of the coating device rotates with the slurry attached to the surface to achieve the coating of the slurry on the battery components, etc. In order to maintain the uniformity of the coating slurry, a coating roller cleaning device is usually configured. The coating roller cleaning device cleans the excess slurry on the coating roller with a scraper to make the slurry evenly attached to the surface of the coating roller.

[0049] Since the relative movement between the scraper and the coating roller will cause the scraper to wear, the scraper needs to be fed toward the coating roller to maintain the distance between the scraper and the coating roller. A feeding mechanism is provided to drive the scraper to rotate so that the scraper can be close to the coating roller, but this also changes the relative angle between the scraper and the coating roller, resulting in uneven wear of the scraper, which in turn affects the uniformity of cleaning.

[0050] In view of the problems existing in the above-mentioned related technologies, the present application proposes a coating roller cleaning device, referring to Figure 1 , Figure 2 and Figure 3 The coating roller cleaning device includes a carrier 100, a first scraper 210 and a first driving member 310. The carrier 100 can move to a working position relative to the coating roller 910. The first scraper 210 is used to clean the slurry on the circumferential surface 911 of the coating roller 910; the first driving member 310 is connected to the carrier 100, and the first driving member 310 includes a first output part 311 for linear motion. The first output part 311 is connected to the first scraper 210. When the carrier 100 is in the working position, the first output part 311 drives the first scraper 210 to move toward or away from the coating roller 910 along a linear path X, so that the first scraper 210 and the circumferential surface 911 maintain a preset gap.

[0051] In the embodiment of the present application, the support frame 100 may be a block structure, a shell structure, a frame structure, etc. The support frame 100 may be integrally formed, or the support frame 100 may include a plurality of frames, which are connected in a detachable or non-detachable manner. Figure 1 In one example, the carrier 100 is a frame structure, and one end of the carrier 100 close to the coating roller 910 has a limiting hole, and the first scraper 210 is inserted into the limiting hole. The inner wall of the limiting hole provides support for the first scraper 210 to reduce the possibility of the first scraper 210 being skewed.

[0052] In an embodiment of the present application, the carrier 100 can move to a working position relative to the coating roller 910, where the working position is when the carrier 100 is close to the coating roller 910 so that the first scraper 210 can clean the slurry on the circumferential surface 911. The movement of the carrier 100 can be linear motion, rotational motion, etc., and the embodiment of the present application does not limit this.

[0053] In the embodiment of the present application, the preset gap is associated with the required slurry thickness on the coating roller 910, that is, during the rotation of the coating roller 910, the slurry passing through the preset gap is retained to continue to adhere to the surface of the coating roller 910, while the slurry with a thickness greater than the preset gap is blocked by the first scraper 210 to be cleaned away by the first scraper 210 relative to the coating roller 910, so that the slurry on the coating roller 910 can be maintained at a desired thickness. It is understandable that in some embodiments, a thicker slurry is required, and a larger preset gap is set, and in other embodiments, a thinner slurry is required, and a smaller preset gap is set.

[0054] In the embodiment of the present application, the support frame 100 provides support for the first driving member 310, and the first driving member 310 can be connected to the support frame 100 by means of clamping, bonding, welding, fastener connection, etc. Figure 1 and Figure 4 In one example, the first driving member 310 is provided with a first mounting plate 312, and the first mounting plate 312 is fixedly connected to the supporting frame 100 by fasteners such as screws.

[0055] In the embodiment of the present application, the first driving member 310 includes a first output part 311 that moves in a linear motion, that is, the first output part 311 moves in a linear motion relative to the carrier frame 100. It can be understood that when the first scraper 210 is connected to the first output part 311, the first scraper 210 also moves along the linear path X with the first output part 311.

[0056] In the embodiment of the present application, the straight path X can be arranged along the radial direction of the coating roller 910, or the straight path X can be arranged along the tangent or secant of the coating roller 910. It can be understood that since the relative angle between the straight path X and the coating roller 910 is fixed, that is, the first scraper 210 does not change the angle relative to the coating roller 910 during the movement of the first output portion 311.

[0057] In the technical solution provided in the embodiment of the present application, the supporting frame 100 provides an installation basis for the first driving member 310 and the first scraper 210. The first scraper 210 can be used to clean the slurry on the circumferential surface 911 of the coating roller 910, so that the slurry is evenly adhered to the circumferential surface 911 of the coating roller 910. The first driving member 310 is used to drive the first scraper 210 to move so as to maintain a preset gap between the first scraper 210 and the circumferential surface 911 of the coating roller 910.

[0058] On this basis, the first driving member 310 includes a first output portion 311, the first output portion 311 moves linearly, and the first scraper 210 is connected to the first output portion 311, so that the first driving member 310 drives the first scraper 210 to move along the linear path X, and then toward or away from the coating roller 910. Since the first scraper 210 moves linearly, the relative angle with the coating roller 910 remains unchanged during the feeding process, reducing the uneven wear of the scraper 200, so that the first scraper 210 and the circumferential surface 911 of the coating roller 910 can maintain a uniform interval, so as to improve the slurry uniformity of the circumferential surface 911 of the coating roller 910. In addition, since the first scraper 210 moves linearly, the space occupied during the movement is small, which is also convenient for its layout in a small space and is conducive to the miniaturization of the coating roller cleaning device.

[0059] Compared with the solution in the related art in which the scraper 200 realizes feeding by rotation, the coating roller cleaning device of the embodiment of the present application drives the first scraper 210 to feed linearly by the first driving member 310, which can improve the wear uniformity of the scraper 200, thereby maintaining the uniformity of the first scraper 210 cleaning the coating roller 910, and is conducive to space saving and miniaturization of the equipment.

[0060] In order to facilitate the feeding of the first scraper 210, in some possible embodiments of the present application, the first driving member 310 is an elastic member, which can at least provide a preset elastic force along the straight path X to drive the first scraper 210 to maintain a preset gap. The preset elastic force can be configured according to actual needs. The preset elastic force can drive the first scraper 210 to move toward the coating roller 910 when the first scraper 210 is worn, until the force exerted by the coating roller 910 on the first scraper 210 is balanced with the preset elastic force, so that the first scraper 210 and the coating roller 910 maintain a preset gap. The elastic member can be a spring, a reed, an elastic rubber pad, etc.

[0061] In some other possible embodiments of the present application, the first driving member 310 is a telescopic cylinder, and the telescopic cylinder is configured with a preset pressure to drive the first scraper 210 to maintain a preset gap. The preset pressure can be configured according to actual needs. The preset pressure can drive the first scraper 210 to move toward the coating roller 910 when the first scraper 210 is worn, until the force exerted by the coating roller 910 on the first scraper 210 is balanced with the preset pressure, so that the first scraper 210 and the coating roller 910 maintain a preset gap. Among them, the telescopic cylinder can be a pneumatic cylinder, a hydraulic cylinder, an electric telescopic rod, etc.

[0062] For example, the first driving member 310 is a cylinder, and the first output part 311 is a piston rod of the cylinder. The cylinder can maintain a stable preset pressure. After the first scraper 210 is worn, the contact pressure between the first scraper 210 and the coating roller 910 decreases. Under the action of the preset pressure, the first scraper 210 moves toward the coating roller 910, thereby realizing automatic feeding, maintaining a preset gap between the first scraper 210 and the coating roller 910, and maintaining the preset gap between the first scraper 210 and the coating roller 910 in a dynamic equilibrium state.

[0063] In the technical solution provided in the embodiment of the present application, an elastic member is used as the first driving member 310, which has a simple structure and is easy to assemble; a telescopic cylinder is used as the first driving member 310, which can provide a stable clamping force to keep the first scraper 210 working smoothly.

[0064] It should be noted that the first scraper 210 of the embodiment of the present application can be movably connected to the supporting frame 100 so that the supporting frame 100 provides support for the first scraper 210; the first scraper 210 can also be only connected to the first driving member 310, so that the first driving member 310 provides support for the first scraper 210.

[0065] In order to maintain the stability of the first scraper 210, refer to Figure 1 and Figure 5In some possible embodiments of the present application, the coating roller cleaning device includes a connecting assembly 400, the connecting assembly 400 includes a first slider 420, the first slider 420 is slidably connected to the carrier 100 along the movement direction of the first output portion 311, and the first scraper 210 is connected to the first slider 420.

[0066] In the embodiment of the present application, the first slider 420 is slidably connected to the carrier 100 , and a guide portion such as a slide rail or a slide groove may be provided on the side of the carrier 100 facing the first scraper 210 , and the extension direction of the guide portion is parallel to the movement direction of the first output portion 311 .

[0067] In the embodiment of the present application, the first scraper 210 slides relative to the guide portion through a slider or the like, and the cross-sectional profile of the guide portion perpendicular to its extension direction can be square, triangular, trapezoidal, T-shaped, etc. It can be understood that the guide portion not only has a guiding function, but also has a limiting function of limiting the movement of the first scraper 210 along the extension direction of the perpendicular guide portion. In addition, the first scraper 210 can also be directly slidably connected to the guide, which is not limited in the embodiment of the present application.

[0068] In the technical solution provided in the embodiment of the present application, a first slider 420 is provided to slidably connect the first scraper 210 to the carrier frame 100. On the one hand, it can be used to correct the feeding direction of the first scraper 210 and improve the movement stability of the first scraper 210. On the other hand, the carrier frame 100 can provide support for the first scraper 210 to keep the first scraper 210 stable during the scraping process.

[0069] In order to facilitate the assembly of the first scraper 210 and the first output portion 311, refer to Figure 1 and Figure 5 In some possible embodiments of the present application, the coating roller cleaning device further includes an adapter 410, which is disposed between the first scraper 210 and the first output portion 311, and the adapter 410 is movably disposed along the vertical straight path X direction.

[0070] In the embodiment of the present application, the adapter 410 is movably arranged, which means that the first scraper 210 and the first output part 311 at both ends of the adapter 410 can move relative to each other along the vertical straight line path X direction, and the adapter 410 may include a deformable connecting end, and during the connection process between the first output part 311 / first scraper 210 and the connecting end, the connecting end is deformed to compensate for the assembly tolerance;

[0071] Alternatively, the adapter 410 includes two relatively movable connecting parts, the two connecting parts are respectively connected to the first scraper 210 and the first output part 311, and the two connecting parts move relative to each other during the connection process to compensate for the assembly tolerance. In one example, the adapter 410 can be a floating coupling.

[0072] In the technical solution provided in the embodiment of the present application, by setting an adapter 410 between the first scraper 210 and the first output part 311, the adapter 410 can be movable to compensate for the assembly error between the two, thereby facilitating the assembly of the first scraper 210 and the first output part 311.

[0073] In order to facilitate the alignment of the second scraper 220 relative to the coating roller 910, refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In some possible embodiments of the present application, the coating roller cleaning device also includes a second driving member 320 and at least two second scrapers 220; the at least two second scrapers 220 are respectively arranged on both sides of the first scraper 210 along a preset direction Y, and the second scraper 220 is used to clean the slurry on the radial surface 912 of the coating roller 910; the second driving member 320 is slidably connected to the carrier 100 along the preset direction Y, and the second driving member 320 includes at least two second output parts 321 that move along the preset direction Y, and the at least two second output parts 321 are connected to at least two second scrapers 220 in a one-to-one correspondence to drive the second scrapers 220 on both sides of the first scraper 210 to move closer to or away from each other; wherein the preset direction Y is perpendicular to the straight path X.

[0074] In an embodiment of the present application, the second driving member 320 may also be a cylinder, a hydraulic cylinder, or an electric telescopic rod. For example, the second driving member 320 is a finger cylinder, which includes two second output parts 321, and the two second output parts 321 are respectively connected to two second scrapers 220, and the two second output parts 321 can be relatively close to or far away from each other.

There may be multiple slide rails or slide grooves, and they are arranged in parallel. In one example, a slide groove is provided on the carrier 100, the second driving member 320 is provided with a second mounting plate 322, the second mounting plate 322 is connected to a second slider 430, and the second slider 430 is slidably connected to the corresponding slide groove along the preset direction Y.

Figure 6 and Figure 7 When one of the second scrapers 220 contacts the coating roller 910 and the other does not, the coating roller 910 will apply a reaction force to the second scraper 220 in contact, so that the force on the second driving member 320 in the preset direction Y is unbalanced. The reaction force will drive the second driving member 320 to slide relative to the supporting member, that is, the second driving member 320 drives the second scraper 220 that is not in contact with the coating roller 910 to move toward the coating roller 910 until both second scrapers 220 effectively contact the coating roller 910, that is, the two second scrapers 220 are aligned relative to the coating roller 910.

[0081] On this basis, when it is necessary to adjust the distance between the second scraper 220 and the first scraper 210, the locking bolt 520 is loosened relative to the supporting frame 100 so that the second scraper 220 can move along the length direction of the strip hole 511. Conversely, the locking bolt 520 is locked relative to the supporting frame 100 to relatively position the second scraper 220 and the first scraper 210.
