The common scraper rollers on the market are equipped with two scraper parts. In actual use, one scraper part is used to scrape the slurry evenly, and the other scraper part is used as a backup. If the scraper part that is currently scraping the slurry is damaged, the position of the scraper roller can be adjusted to use the backup scraper part to scrape the slurry, thereby ensuring the normal operation of lithium battery production.

[0031] To better understand the technical solutions and beneficial effects of the present application, the present application is further described in detail below with reference to specific embodiments:

[0032] See also Figures 1 to 3, which is a coating device 10 according to an embodiment of the present invention, comprising a machine base 100, a coating assembly 200 and a protective assembly 300, wherein the machine base 100 comprises two fixed plates 110 and two vertical plates 120, the two fixed plates 110 being arranged relatively parallel, each of the fixed plates 110 being used for being fixedly mounted on a workbench (not shown), each of the vertical plates 120 being arranged on the corresponding fixed plate 110, a guide plate 130 being arranged obliquely between the two vertical plates 120, the guide plate 130 and the two vertical plates 120 jointly forming a pouring area 101; the coating assembly 200 comprises a coating Roller 210, scraper roller 220 and conveying roller 230, each of the fixed plates 110 is provided with a first card seat 112 and a second card seat 114, each of the first card seats 112 is arranged adjacent to the corresponding vertical plate 120, the two ends of the coating roller 210 are rotatably connected to the two first card seats 112, and a loading area 102 is formed between the coating roller 210 and the lower end of the guide plate 130, and the loading area 102 is connected to the unloading area 101; the two ends of the scraper roller 220 are detachably connected to the two vertical plates 120, and the scraper roller 220 is located at the coating roller 210. Directly above, the scraper roller 220 is provided with a first scraper portion 222 and a second scraper portion 224, the first scraper portion 222 and the second scraper portion 224 are arranged opposite to each other, and the first scraper portion 222 is arranged adjacent to the coating roller 210; each second card seat 114 is arranged adjacent to the corresponding first card seat 112, and the two ends of the conveying roller 230 are rotatably connected to the two second card seats 114, the conveying roller 230 and the coating roller 210 are rotated away from the direction of the guide plate 130, and the conveying roller 230 is arranged parallel to the coating roller 210, and the conveying roller 2 30 and the coating roller 210 form a pole piece passing area 201; the protective component 300 includes an anti-scraping member 310, two first magnetic strips 320 and two second magnetic strips 330, the two first magnetic strips 320 are both attached to the scraper roller 220, and the two first magnetic strips 320 are respectively located on both sides of the second scraper portion 224, the two second magnetic strips 330 are both arranged in the anti-scraping member 310, the two second magnetic strips 330 are arranged in a one-to-one correspondence with the two first magnetic strips 320, and each second magnetic strip 330 is magnetically adsorbed to the corresponding first magnetic strip 320.

[0033] In this embodiment, the guide plate 130 and the two vertical plates 120 together form a pouring area 101, and a loading area 102 is formed between the lower end of the guide plate 130 and the coating roller 210. The loading area 102 is connected to the pouring area 101. Therefore, the slurry is first poured through the pouring area 101, and then the slurry flows into the loading area 102 through the guide plate 130; at this time, the coating roller 210 rotates away from the guide plate 130, so that the surface of the coating roller 210 is adhered to the slurry, and the scraper roller 220 The first scraper portion 222 is located directly above the coating roller 210 and is adjacent to the coating roller 210. When the portion of the coating roller 210 coated with the slurry rotates to the position of the first scraper portion 222, the first scraper portion 222 scrapes the excess slurry on the surface of the coating roller 210 evenly. Then, the portion of the coating roller 210 coated with the slurry rotates to a position adjacent to the conveying roller 230. The conveying roller 230 is used to convey the electrode, and the rotation direction of the conveying roller 230 is the same as that of the coating roller 210. In addition, the coating roller 2 10 and the conveying roller 230 form a pole piece passing area 201. When the pole piece passes through the pole piece passing area 201, the slurry on the coating roller 210 will be evenly coated on the surface of the pole piece. After the coating is completed, the pole piece part is sent to the next process by the conveying roller 230. Among them, the two ends of the scraper roller 220 are detachably connected to the two vertical plates 120, and the scraper roller 220 is provided with a first scraper part 222 and a second scraper part 224. When the first scraper part 222 is damaged, the scraper roller 220 can be disassembled and adjusted to remove the scraper roller 220. The second scraper portion 224 is used to scrape the slurry at the position of the scraper roller 220. It can be understood that by providing a scratch-resistant member 310 with two second magnetic strips 330 disposed therein, and two first magnetic strips 320 attached to either side of the second scraper portion 224, each second magnetic strip 330 is adsorbed and connected to the corresponding first magnetic strip 320, the scratch-resistant member 310 is tightly adhered to the surface of the scraper roller 220. The scratch-resistant member 310 is also positioned over the second scraper portion 224 to prevent scratches on the operator. In one embodiment, the scratch-resistant member 310 is curved. Since the scraper roller 220 is cylindrical, the scratch-resistant member 310 is configured as a curved structure to better adapt to the surface of the scraper roller 220. In another embodiment, the scratch-resistant member 310 is a flexible deformable member. In this way, by applying pressure to the anti-scraping member 310 , the anti-scraping member 310 is deformed into an arc shape, thereby enabling the anti-scraping member 310 to be adapted and attached to the surface of the scraper roller 220 .

[0034] In the embodiment, when the second doctor blade part 224 is used to scrape the slurry instead of the first doctor blade part 222, the position of the doctor roll 220 needs to be adjusted so that the second doctor blade part 224 is arranged adjacent to the coating roll 210, while the first doctor blade part 222 is idle. At this time, the connection between each second magnetic strip 330 and the corresponding first magnetic strip 320 is disconnected, the anti-scraping piece 310 is removed from the surface of the second doctor blade part 224, the two first magnetic strips 320 are respectively attached to the two sides of the first doctor blade part 222, and finally each second magnetic strip 330 is adsorbed and connected with the corresponding first magnetic strip 320, so that the anti-scraping piece 310 covers the first doctor blade part 222. In this way, the protection assembly 300 can be detachably connected to the doctor roll, so that when the first doctor blade part 222 and the second doctor blade part 224 are used alternately, the protection assembly 300 can be flexibly disassembled and assembled, so that the anti-scraping piece 310 covers the idle one of the first doctor blade part 222 and the second doctor blade part 224, thereby avoiding the problem of the operator being scratched, and realizing the recycling use of the protection assembly 300.

[0035] It can be understood that the material guide plate 130 and the two vertical plates 120 together form the material pouring area 101, the coating roll 210 is arranged adjacent to the material pouring area 101, the conveying roll 230 is arranged adjacent to the coating roll 210, and the doctor roll 220 is arranged directly above the coating roll 210. Therefore, when the slurry is poured into the material pouring area 101, it is inevitable that the slurry will splash, and a part of the splashed slurry will fall on the doctor roll 220, and even a part of the slurry will fall on the pole piece of the conveying roll 230. It should be noted that the pole piece conveyed on the conveying roll 230 has been coated with uniform slurry, and when the splashed slurry falls on the pole piece, it will cause the slurry on the pole piece to be unevenly distributed, thereby affecting the electrochemical performance of the battery.

[0036] In order to avoid the problem that the slurry splashes on the pole piece of the conveying roll 230, in one of the embodiments, please refer to Figure 4 and Figure 5The anti-scraping member 310 includes a shielding portion 312 and a covering portion 314 that are connected to each other. Two second magnetic strips 330 are provided in the covering portion 314. The shielding portion 312 is provided on the side of the covering portion 314 away from the scraper roller 220. The top of the shielding portion 312 is flush with the top of each vertical plate 120. In this embodiment, since the anti-scraping member 310 includes a shielding portion 312 and a covering portion 314, two second magnetic strips 330 are provided in the covering portion 314, and each second magnetic strip 330 is adsorbed and connected to the corresponding first magnetic strip 320, so that the covering portion 314 is tightly attached to the surface of the scraper roller 220, and the covering portion 314 is firmly used to cover the second scraper portion 224; at this time, the shielding portion 312 is located on the side of the covering portion 314 away from the scraper roller 220, and the top of the shielding portion 312 is flush with the top of each vertical plate 120. Therefore, when pouring the slurry through the pouring area 101, even if the slurry splashes out, due to the shielding effect of the shielding portion 312, the splashed slurry will fall on the shielding portion 312, thereby avoiding the slurry splashing on the pole piece of the conveying roller 230, causing the problem of poor electrical performance of the battery. Furthermore, the shielding portion 314 itself is used to shield the second scraper portion 224 to prevent scratches on the operator. The shielding portion 312 is located above the shielding portion 314, resulting in a thicker anti-scratch member 310 formed by the shielding portion 312 and the shielding portion 314. This improves the anti-scratch member 310's ability to shield the second scraper portion 224 and enhances the anti-scratch member 310's performance against scratches on the operator. Furthermore, the shielding portion 312 and the shielding portion 314 are integrally formed. In this way, the overall structural strength of the anti-scratch member 310 is improved, and the separation between the shielding portion 312 and the covering portion 314 when the anti-scratch member 310 is used is avoided; it can be understood that the shielding portion 312 is arranged on the scraper roller 220 through the connection with the covering portion 314. When the shielding portion 312 is separated from the covering portion 314, the shielding portion 312 will fall from the covering portion 314, affecting the coating process of the electrode, and in the absence of the shielding portion 312, there is still the problem of slurry splashing onto the electrode, resulting in poor electrochemical performance of the battery.

[0037] Although the shielding portion 312 effectively prevents slurry from splashing onto the pole piece, it also makes the overall thickness of the anti-scratch member 310 thicker, thereby increasing the weight of the anti-scratch member 310. Furthermore, the anti-scratch member 310 is disposed on the scraper roller 220. The heavy anti-scratch member 310 may cause each second magnetic strip 330 to become loosely attached to the corresponding first magnetic strip 320, creating the risk of the anti-scratch member 310 falling off the scraper roller 220. To address this issue, both the shielding portion 312 and the cover portion 314 are made of pearl cotton. In this way, the anti-scraping member 310 composed of the shielding portion 312 and the covering portion 314 is lighter, avoiding the problem of loose adsorption between each second magnetic strip 330 and the corresponding first magnetic strip 320, thereby preventing the anti-scraping member 310 from falling from the scraper roller 220; it can also be understood that since the anti-scraping member 310 is covered on the second scraper portion 224, and the overall weight of the anti-scraping member 310 is lighter, it is negligible relative to the weight of the scraper roller 220 itself, thereby avoiding the problem of the anti-scraping member 310 crushing the second scraper portion 224; and the pearl cotton has good flexible deformation ability, which is convenient for bending it into an arc shape, so that it can better adapt to the surface of the scraper roller 220.

[0038] In order to save production resources and prevent the slurry from splashing onto the electrode, please refer to Figure 4 and Figure 5, the shielding part 312 is a right triangular prism, and the two sides of the shielding part 312 are respectively formed with a first shielding surface 3121 and a second shielding surface 3122. In the embodiment, the cover part 314 is connected to the surface of the material scraping roller 220 by adsorption. Since the anti-scratching piece 310 is a right triangular prism, that is, the longitudinal section of the shielding part 312 is an equilateral triangle, the pressure applied by the two sides of the shielding part 312 to the cover part 314 is equal, which can better avoid the problem of unstable adsorption between the cover part 314 and the material scraping roller 220 due to uneven pressure on the two ends of the cover part 314. It can be understood that the bottom end of the shielding part 312 is connected to the top end of the cover part 314. In the case that the area of the bottom end of the shielding part 312 does not change, setting the shielding part 312 as a right triangular prism to some extent reduces the raw materials used to produce the shielding part 312, and realizes the shielding of the splashed pulp while avoiding the waste of production resources. It should be noted that since the shielding part 312 is formed with the first shielding surface 3121 and the second shielding surface 3122, in actual use, the first shielding surface 3121 is first arranged adjacent to the material pouring area 101. When the pulp splashes onto the first shielding surface 3121 and gradually condenses enough pulp on the first shielding surface 3121, the adsorption connection between the cover part 314 and the material scraping roller 220 is disconnected, the shielding part 312 is reversed, so that the second shielding surface 3122 is arranged adjacent to the material pouring area 101, and the second shielding surface 3122 is used to shield the splashed pulp. In this way, the utilization of the shielding part 312 is maximized, and the production resources are saved. It can also be understood that the shielding part 312 is a right triangular prism, and the cover part 314 and the shielding part 312 are an integral structure. Because the anti-scratching piece 310 composed of the cover part 314 and the shielding part 312 can be set as a right triangular prism, the shape of the anti-scratching piece 310 is more regular, which is easy to mass produce and improves the production efficiency of the anti-scratching piece 310.

[0039] In order to realize the recycling use of the anti-scratching piece 310, when enough pulp accumulates on the shielding part 312, the anti-scratching piece 310 needs to be removed and cleaned. However, since the cover part 314 is provided with two second magnetic strips 330, during the cleaning process of the anti-scratching piece 310, the second magnetic strips 330 are easily damaged, thereby affecting the adsorption connection between the anti-scratching piece 310 and the material scraping roller 220. Based on this, further, please refer to Figure 5The cover setting portion 314 is formed with two limiting installation grooves 314a, each of which is used for accommodating one second magnetic strip 330, and each of which is a through groove. In this embodiment, by setting two limiting installation grooves 314a for accommodating two second magnetic strips 330 respectively, each second magnetic strip 330 can be reliably arranged in the cover setting portion 314, so that the anti-scratching piece 310 and the scraping roller 220 can be reliably adsorbed and connected. Since each limiting installation groove 314a is a through groove, the second magnetic strip 330 can be easily taken out or placed in the limiting installation groove 314a. Therefore, when the anti-scratching piece 310 is cleaned and maintained, the second magnetic strip 330 is taken out to avoid damage to the second magnetic strip 330. After the anti-scratching piece 310 is cleaned, the second magnetic strip 330 is arranged in the corresponding limiting installation groove 314a, so that the anti-scratching piece 310 can be recycled, saving production resources.

[0040] In one embodiment, please refer to Figure 1The scraper roller 220 includes a roller body 220a and a roller shaft 220b. The machine base 100 also includes two mounting blocks 140. Each mounting block 140 is formed with a welding hole 1401. The shaft of the roller shaft 220b is connected to the roller body 220a, and the two ends of the roller shaft 220b are respectively welded to the inner walls of the two welding holes 1401; the two mounting blocks 140 are correspondingly arranged with the two vertical plates 120. Each mounting block 140 is also formed with a through mounting hole 1402. Each vertical plate 120 is formed with a screw hole (not shown in the figure). The screw hole of each vertical plate 120 is connected to the corresponding mounting hole 1402 of the mounting block 140. The machine base also includes two fasteners (not shown in the figure). Each fastener is passed through one of the mounting holes 1402 and is screwed to the inner wall of the corresponding screw hole. Roller body 220a In this embodiment, the roller body 220a has an axial thread of the roller shaft 220b connected to the roller body 220a, and the scraper roller 220 is fixed to the two mounting blocks 140 by welding the two ends of the roller shaft 220b to the inner walls of the two welding holes 1401 respectively; and since each mounting block 140 is formed with a through mounting hole 1402, each vertical plate 120 is formed with a screw hole, and the screw hole of each vertical plate 120 is connected to the corresponding mounting hole 1402 of the mounting block 140, each fastener is passed through a mounting hole 1402 and screwed to the inner wall of the corresponding screw hole, so that each mounting block 140 is fixedly installed on the corresponding vertical plate 120, thereby completing the installation of the scraper roller 220. It can be understood that when the first scraper portion 222 is damaged, the scraper roller 220 is disassembled by disconnecting the connection between each mounting block 140 and the corresponding vertical plate 120, and then the position of the scraper roller 220 is adjusted so that the second scraper portion 224 is set adjacent to the coating roller 210, and then each mounting block 140 is fixedly installed on the corresponding vertical plate 120; in this way, the scraper roller 220 can be conveniently disassembled or installed, the first scraper portion 222 and the second scraper portion 224 can be flexibly replaced, and the slurry stains on the scraper roller 220 can be cleaned in time.

[0041] Further, see Figure 1 and Figure 2 The roller body 220a and the roller shaft 220b are integrally formed, thereby improving the structural strength of the scraper roller 220.

[0042] In one embodiment, see Figure 1 and Figure 2The length of the first scraper portion 222 is equal to the length of the second scraper portion 224, and the length of the second scraper portion 224 is equal to the length of the roller body 220a. In this embodiment, the second scraper portion 224 is a backup option for the first scraper portion 222. The length of the second scraper portion 224 is set to be equal to the length of the first scraper portion 222, so that the two scraping effects are equal. The length of the second scraper portion 224 is equal to the length of the roller body 220a, that is, the length of the first scraper portion 222 is also equal to the length of the roller body 220a, thereby ensuring that the first scraper portion 222 and the second scraper portion 224 have sufficient length for scraping the slurry.

[0043] Furthermore, the length of the anti-scraping member 310 is greater than or equal to the length of the second scraper portion 224. In this way, the anti-scraping member 310 can be well covered on the surface of the second scraper portion 224, thereby preventing the operator from being scratched by the second scraper portion 224.

[0044] In one embodiment, see Figure 3 The two second magnetic strips 330 are respectively disposed adjacent to the ends of the anti-scraping member 310. Thus, when each second magnetic strip 330 is adsorbed and connected to the corresponding first magnetic strip 320, the entire anti-scraping member 310 is tightly adhered to the surface of the scraper roller 220, allowing the anti-scraping member 310 to more securely cover the second scraper portion 224, thereby more reliably protecting the operator's safety.

[0045] In one embodiment, see Figure 1 and Figure 2 The coating device 10 further includes a drive assembly 400, which includes two drive motors 410. The output end of each drive motor 410 is connected to one end of the conveying roller 230. Each second holder 114 is provided with a rotation hole 1141. The two ends of the conveying roller 230 are respectively rotatably connected to the inner walls of the two rotation holes 1141. In this embodiment, by providing two drive motors 410, the two ends of the conveying roller 230 are respectively rotatably connected to the inner walls of the two rotation holes 1141, and the rotation of the conveying roller 230 transports the electrode coated with slurry.

[0046] In one embodiment, the rotation speed of the conveying roller is the same as the rotation speed of the coating roller, so that the electrode can be coated with slurry synchronously when it moves through the conveying roller.

[0047] In one embodiment, see Figure 1The coating assembly 200 further includes a feed driven roller 240, which is located on the side of the conveying roller 230 away from the coating roller 210. The feed driven roller 240 is used to convey the electrode sheet into the oven. Each of the fixed plates 110 is further provided with a connecting plate 118. The two ends of the feed driven roller 240 are respectively rotatably connected to the two connecting plates 118, and the feed driven roller 240 and the conveying roller 230 rotate in the same direction. In this embodiment, by providing the feed driven roller 240, the electrode sheet after being coated is conveyed by the conveying roller 230 and then passes through the feed driven roller 240, and then the feed driven roller 240 conveys the electrode sheet into the oven for the next process.

[0048] The present invention further provides a coating device, comprising a pouring device and the coating device as described in any of the above embodiments, wherein the discharge end of the pouring device is located directly above the pouring area.

[0049] Compared with the prior art, the present invention includes but is not limited to the following advantages:

[0050] 1. By setting up an anti-scratch member with two second magnetic strips inside, and attaching two first magnetic strips to both sides of the second scraper part, and then adsorbing and connecting each second magnetic strip to the corresponding first magnetic strip, the anti-scratch member is tightly attached to the surface of the scraper roller, and the anti-scratch member cover is set on the second scraper part to avoid scratching the operator;

[0051] 2. Since the protective component can be detachably connected to the scraper rod, when the first scraper part and the second scraper part are replaced, the protective component can be flexibly disassembled and assembled so that the anti-scratching part can cover the idle one of the first scraper part and the second scraper part, thereby avoiding the problem of the operator being scratched and realizing the recycling of the protective component.

[0052] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
