The inventor has noticed that, when the coating apparatus performs a coating operation on the current collector or other membrane, if foreign matters (such as slurry or dust impurities) adhere to the coating back roller of the coating apparatus, the current collector or other membrane partially abuts against the coating back roller, and partially abuts against the foreign matters, so that the current collector or other membrane is not flat. Later when the mass flow body or other diaphragms are driven to the coating die head by the coating back roll, the mass flow body also can contact with the coating die head unevenly, and then make the coating die head can't carry out even coating to the mass flow body. Even when severe, the current collector or other film sheet may be torn by foreign matter adhering to the coating back roller.

Therefore, in order to remove foreign matters adhered to the coating back roller in time, the coating effect of the coating equipment is improved. Referring to fig. 1 and 2 in combination, the present invention provides a coating apparatus 100, and in an embodiment of the present invention, the coating apparatus 100 includes a frame 1, a coating mechanism 2, and a scraping mechanism 3. The coating mechanism 2 comprises a coating back roller 21 and a coating die head 23, the coating back roller 21 is rotatably arranged on the frame 1, and the coating die head 23 is arranged on the frame 1 and is provided with a discharge end facing the coating back roller 21; the scraping mechanism 3 is provided in the frame 1 and abuts against the side peripheral surface of the application back roller 21.

The frame 1 may serve as a bearing mechanism of the coating apparatus 100, so as to be used for improving installation positions of the coating mechanism 2, the scraping mechanism 3 and the like, thereby facilitating the assembly of the mechanisms of the coating apparatus 100 into a whole by being installed on the frame 1. The shape of the frame 1 may be any shape, i.e., a cube, a rectangular parallelepiped, or other shapes. The specific structure may be formed by enclosing a plurality of plate bodies, or formed by combining a plurality of columns, or formed by combining plate body assembly columns, etc., the specific structure of the frame 1 is not limited in the present application, and it is only required to ensure that the coating mechanism 2, the scraping mechanism 3, or other mechanisms of the coating apparatus 100 can be installed and supported. The coating mechanism 2 may be configured to drive the current collector 200 or other membranes to be conveyed according to a preset conveying direction, that is, to drive the coating back roller 21 to rotate to drive the current collector 200 or other membranes to be conveyed. Meanwhile, in the conveying process, the current collector 200 or other membranes pass through the coating die head 23, the coating die head 23 can store active material slurry or other material slurry, and the slurry is output through the discharge end of the coating die head 23 to be coated on the current collector 200 or other membranes, so that the coating work of the current collector 200 or other membranes is realized. In order to improve the stability of the coating mechanism 2 in conveying the current collector 200 or other films, the coating mechanism 2 may further include an abutting roller 25, the abutting roller 25 may be rotatably disposed on the frame 1, and is spaced from the coating back roller 21 side by side, so that the current collector 200 or other films may be better driven by friction force under the clamping between the coating back roller 21 and the abutting roller 25. The scraping mechanism 3 can be used for abutting against the side peripheral surface of the coating back roller 21, and further, in the rotation process of the coating back roller 21, the coating back roller 21 can rotate, and the foreign matters adhered to the coating back roller 21 can be blocked by the scraping mechanism 3 abutting against the coating back roller 21 to realize the separation from the coating back roller 21, so that the scraping cleaning of the side peripheral surface of the coating back roller 21 is realized. The part of the scraping mechanism 3 for abutting and scraping the coating back roller 21 may be a plate structure (for example, a scraper 32 described below), or may be a block structure (for example, a sponge block), or a cylinder structure (for example, a cleaning roller), and the like.

When the coating device 100 of the present application is used, the coating back roll 21 can drive the current collector 200 to be conveyed along a preset direction. And when the current collector 200 is transported between the coating back roll 21 and the coating die head 23, the discharge end of the coating die head 23 faces the coating back roll 21, so that the current collector 200 can be coated with active material substances through the coating die head 23, and the current collector 200 is subjected to primary processing to form an electrode plate. Further, the coating apparatus 100 of the present application further includes a scraping mechanism 3, and the scraping mechanism 3 may abut against a side circumferential surface of the coating back roller 21. In this way, during the rotation of the application back roller 21, the wiping mechanism 3 performs wiping cleaning of the side circumferential surface of the application back roller 21. In other words, coating apparatus 100 in this application can carry out timely cleaing away to the foreign matter that adheres on coating back-up roll 21 through the setting of scraping mechanism 3 to make current collector 200 can keep smooth transport, and then can evenly butt with this coating die head 23 when current collector 200 is driven to pass through coating die head 23 by coating back-up roll 21, thereby realize that coating die head 23 carries out even coating to current collector 200. At the same time, such an arrangement also avoids the possibility of the current collector 200 being pierced by foreign matter adhering to the coating back roller 21. Therefore, the coating apparatus 100 in the present application improves the coating effect of the coating apparatus 100 due to the provision of the wiping mechanism 3. Further, the scraping mechanism 3 of the coating apparatus 100 in the present application is continuously abutted against the coating back roller 21, so that scraping cleaning of the side peripheral surface of the coating back roller 21 can be achieved as soon as the coating back roller 21 is turned on. Therefore, the coating apparatus 100 of the present application performs the scraping cleaning work of the coating back roller 21 by the scraping mechanism 3 in real time during the work of the coating back roller 21. This makes it unnecessary for the coating apparatus 100 to perform the coating work on the current collector 200 and the cleaning work on the coating back roller 21 separately, thereby contributing to an improvement in the working efficiency of the coating apparatus 100.

Referring to fig. 2, in an embodiment of the present invention, the scraping mechanism 3 includes a mounting seat 31 and a scraper 32, the mounting seat 31 is disposed on the frame 1; one side of the doctor blade 32 is connected to the mounting base 31, and the other opposite side is in contact with the side peripheral surface of the application back roller 21.

The mounting seat 31 may be used to provide a mounting position for the scraper 32 to mount and fix the scraper 32. Meanwhile, a connecting position can be provided through the mounting seat 31 to fix the mounting seat 31 to the rack 1, thereby realizing the mounting and fixing of the scraping mechanism 3 on the rack 1. The mounting seat 31 may have any shape such as a rectangular parallelepiped structure or a cube, and may be used to mount the scraper 32 and connect to the frame 1. The doctor blade 32 can be used to stably abut against the side peripheral surface of the coating back roll 21 so as to better apply a scraping force to the foreign matter adhering to the coating back roll 21.

In this embodiment, a connection structure may be conveniently provided by the mounting seat 31 to mount the scraping mechanism 3 on the frame 1. The provision of the blade 32, as described above, can exert a better scraping force, thereby contributing to an improvement in the scraping cleaning effect of the application backing roller 21. Moreover, since the volume of the scraper 32 is relatively small, the overall volume of the scraping mechanism 3 is not excessive, thereby facilitating the installation of the scraping mechanism 3 in a limited installation space. Of course, the present invention is not limited to this, and in another embodiment, the scraping mechanism 3 may be composed of a cleaning roller, and then the cleaning roller may be brought into contact with the side circumferential surface of the application back roller 21.

Further, referring to fig. 2 to fig. 4, the mounting base 31 includes a first clamping plate 311 and a second clamping plate 315, the second clamping plate 315 is connected to the first clamping plate 311 and cooperates with the first clamping plate 311 to clamp the fixed scraper 32, and at least one of the second clamping plate 315 and the first clamping plate 311 is further connected to the frame 1.

The first clamping plate 311 and the second clamping plate 315 may be used for a mating connection to clamp and fix a side of the doctor blade 32 away from the coating back roll 21, thereby achieving clamping and installation of the doctor blade 32 on the mounting seat 31. The first clamping plate 311 and the second clamping plate 315 may be rectangular parallelepiped, square, or other shapes. In addition, in order to fix the mounting seat 31 to the frame 1, only the first clamping plate 311 may be connected to the frame 1, only the second clamping plate 315 may be connected to the frame 1, or both the first clamping plate 311 and the second clamping plate 315 may have a connection relationship with the frame 1.

In this embodiment, the scraper 32 is clamped and fixed by the first clamping plate 311 and the second clamping plate 315, so that the scraper 32 does not need to be provided with a connecting structure, and the first clamping plate 311 and the second clamping plate 315 can be directly connected. At this time, the structure of the blade 32 itself may not be affected by the connecting structure, thereby advantageously ensuring the strength of the blade 32 itself for the subsequent blade 32 to perform stable scraping cleaning of the foreign matter adhered to the application back roller 21.

Further, referring to fig. 4, the second clamping plate 315 and the first clamping plate 311 are connected by a screw 33.

The screw 33 is a screw or a combination of a stud and a nut, that is, the first clamping plate 311 and the second clamping plate 315 can be locked by passing through the screw; or, a stud is arranged on one of the first clamping plate 311 and the second clamping plate 315, and then a nut is sleeved after the stud passes through one of the first clamping plate 311 and the second clamping plate 315 for locking.

In the present embodiment, the second clamping plate 315 and the first clamping plate 311 are connected by the screw 33, so that both the first clamping plate 311 and the second clamping plate 315 can be detached. This allows the scraper 32 mounted between the first clamping plate 311 and the second clamping plate 315 to be removed and replaced to avoid partial failure or damage to the scraping mechanism 3 which would require costly replacement of the entire scraper. Moreover, the screw 33 connection also has the advantage of simplicity and stability, so that the process of attaching and detaching the scraper 32 can be simplified while ensuring the stability of fixing the scraper 32. Of course, it should be noted that the present disclosure is not limited thereto, and in other embodiments, the first clamping plate 311 and the second clamping plate 315 may also be fixed by a snap connection or a magnetic attraction. In addition, in order to improve sufficient abutment of the doctor blade 32 against the application back roller 21 in the axial direction thereof, the doctor blade 32 may be provided extending along the rotational axis of the application back roller 21. At this time, in order to ensure the stability of fixing the doctor blade 32, the first holding plate 311 and the second holding plate 315 may be extended along the rotation axis of the coating back roll 21.

Further, referring to fig. 4, the scraping mechanism 3 further includes a stop plate 34, the stop plate 34 is connected to the first clamping plate 311 or the second clamping plate 315 in the mounting seat 31, and is at least partially located on a side of the mounting seat 31 away from the scraper 32; the stopper plate 34 and the first clamping plate 311 or the second clamping plate 315 enclose a collecting space 341, and the collecting space 341 is used for accommodating foreign matters scraped by the scraper 32 on the coating back roller 21.

The stopper plate 34 may be used to block foreign substances caught by the blade 32 from the coating back roller 21 to prevent the foreign substances from falling into the coating apparatus 100 or on the floor to be inconvenient to clean. The stop plate 34 may be located entirely on a side of the mounting seat 31 away from the side where the scraper 32 is mounted, and in this case, the stop plate 34 may be formed as a plate body. Of course, the stop plate 34 may be partially located on the side of the mounting seat 31 away from the side where the scraper 32 is mounted, and another portion may be located at the opposite ends of the mounting seat 31 in the axial direction of the coating back roller 21, in which case the stop plate 34 may be formed by enclosing three plate bodies. Therefore, the present application does not limit the specific form of the collecting space 341 defined by the stopper plate 34 and the first clamping plate 311 or the second clamping plate 315, and the foreign matter caught by the scraper 32 from the coating back roller 21 may be collected. When the first clamping plate 311 is located below and the second clamping plate 315 is located above, the stopper plate 34 may be disposed on the second clamping plate 315. That is, the stopper plate 34 in the present application may be provided on the upper one of both the first and

second chucking plates

311 and 315. In order to improve the smoothness of the foreign matter scraped off by the scraper 32 entering the collecting space 341, the first clamping plate 311 or the second clamping plate 315 in the mounting seat 31 is provided with a guide surface 317 on a side close to the scraper 32, and the guide surface 317 is used for guiding the foreign matter scraped off by the scraper 32 on the coating back roller 21 into the collecting space 341. At this time, the guide surface 317 is provided so that there is no excessive height difference between the scraper 32 and the first clamping plate 311 or the second clamping plate 315, thereby facilitating the foreign materials scraped off by the scraper 32 to enter the collection space 341. The guide surface 317 may be an inclined surface to make it more regular and easier to machine. Of course, the present application is not limited thereto, and in other embodiments, the guide surface 317 may also be a curved surface.
