[0027] Reference Figure 1 as well as Figure 2 A sodium ion battery electrode coating device includes a docking frame 1, a coating area is provided below the docking frame 1, a storage mechanism 2 and a scraping mechanism 3. During operation, the electrode passes through the coating area, the storage mechanism 2 stores the material and promptly applies the material to the electrode, and the scraping mechanism 3 is used to scrape the material on the electrode to control the coating height.

[0028] Specifically, the docking frame 1 is used to support the storage mechanism 2 and the scraping mechanism 3. The docking frame 1 includes a frame body 11. In order to facilitate connection with external equipment such as a conveyor belt, the frame body 11 has several docking parts 12. The docking parts 12 are located on both sides of the length direction of the frame body 11. Several docking parts 12 are installed with docking bolts 121. The docking frame 1 can be threadedly connected to the conveyor belt through these docking bolts 121, thereby facilitating installation and disassembly.

[0029] Reference Figure 1 、 Figure 2 as well as Figure 3The storage mechanism 2 includes a storage assembly 21 arranged on the docking frame 1. The storage assembly 21 includes a storage barrel 211. The storage barrel 211 is a storage barrel 211 with an ultrasonic function, that is, the storage barrel 211 is provided with an ultrasonic generator (not shown in the figure), which uses ultrasonic waves to disperse and separate the materials in the discharge barrel. The storage barrel 211 has a feed port and a discharge port. The feed port is located above the storage barrel 211, and the storage port is located below the storage barrel 211. The discharge port of the storage barrel 211 is arranged on the docking frame 1 and faces the coating area. The discharge port is provided with a discharge valve 212 for controlling the flow of materials. The discharge valve 212 can specifically be a solenoid valve, or an electric valve; the feed port is provided with an end cover 213 for closing the storage barrel 211.

[0030] Since the material needs to be stored in the storage mechanism 2 for a long time, in order to prevent the material from settling and piling up, the storage mechanism 2 further includes a stirring assembly 22 provided in the storage assembly 21. In this embodiment, the stirring assembly 22 includes a stirring motor 221 provided in the storage barrel 211 and a stirring shaft 222 provided in the stirring motor 221. The stirring motor 221 is provided in the end cover 213. The stirring shaft 222 is located in the storage barrel 211 and extends along the length direction of the storage barrel 211. The stirring shaft 222 is provided with a plurality of stirring blade groups 223. To ensure the stirring effect, the plurality of stirring blade groups 223 are provided along the circumferential direction of the stirring shaft 222. The stirring blade group 223 includes a plurality of stirring blades, and the plurality of stirring blades are evenly provided along the length direction of the stirring shaft 222. By providing the stirring blade group 223, the contact area between the stirring assembly 22 and the material can be effectively increased, thereby improving the stirring effect and stirring efficiency.

[0031] In addition, to prevent the material from adhering to the inner wall of the storage barrel 211, the stirring assembly 22 also includes a plurality of elastic scrapers 224. In this embodiment, there are four elastic scrapers, which are arranged on the stirring shaft 222 and are evenly arranged along the circumferential direction of the stirring shaft 222. The height of the four elastic scrapers 224 corresponds to the height of the stirring blade group 223. The four elastic scrapers 224 are arranged vertically and fit the inner wall of the storage barrel 211. At the same time, the stirring assembly 22 also includes elastic scrapers and spiral blades 225. The spiral blades 225 are arranged in a spiral transition and are arranged on the stirring shaft 222 and are located on the side of the stirring blade group 223 close to the coating area, that is, the spiral blades 225 are arranged below the stirring blade group 223 and close to the discharge port.

[0032] By setting up the stirring assembly 22 in this way, the stirring motor 221 is powered on and started to drive the stirring blade group 223 and the elastic scraper 224 to rotate through the stirring shaft 222, so that the material can be fully stirred and the material can be prevented from sticking to the inner wall of the storage barrel 211. After stirring, the material enters the spiral blade 225. The rotating spiral blade 225 can guide the material, so that the material enters the discharge port faster, thereby improving the discharge efficiency.

The scraper mechanism 3 includes a scraper assembly 31 that is slidably connected to the docking frame 1 and a drive assembly 32 for driving the scraper assembly 31. The scraper assembly 31 is oriented toward the coating area. In this embodiment, the scraper assembly 31 includes a scraper 311. The scraper 311 is oriented toward the coating area. The scraper 311 has limit sliders 312 at both ends of the length direction. The limit sliders 312 are T-shaped sliders. Correspondingly, limit slots 111 for cooperating with the limit sliders 312 are formed at both ends of the docking frame 1. The limit slots 111 are T-shaped slots. The limit slots 111 are vertically arranged and extend along the height direction of the docking frame 1. The limit sliders 312 are slidably connected to the limit slots 111.

[0034] The drive assembly 32 includes a drive cylinder 321 mounted on the docking frame 1, a telescopic rod 322 mounted on the drive cylinder 321, and an output rod 323 mounted on the telescopic rod 322. The drive cylinder 321 is mounted with a plurality of assembly bolts 3211. The docking frame 1 is provided with assembly threaded holes 112 for engaging the assembly bolts 3211. The drive cylinder 321 is threadedly connected to the docking frame 1 via the assembly bolts 3211 to achieve a detachable connection. A fixed block 313 is provided in the middle of the length of the scraper 311. The output rod 323 is connected to the fixed block 313. Specifically, the output rod 323 can be fixedly connected to the fixed block 313. With this arrangement, the drive cylinder 321 can be used to drive the scraper 311 to slide along the limiting slide 111, thereby moving closer to or further away from the coating area. By adjusting the height of the scraper 311 by the drive cylinder 321, the coating height of the material on the electrode can be adjusted. In order to facilitate the operator's observation and comparison, the scraping mechanism 3 also includes a scale 33 arranged on the docking frame 1. The scale 33 is located on one side of the scraper 311. In this embodiment, there are two groups of scales 33 and they are located on both sides of the length of the docking frame 1. The scales 33 face the coating area and are located on both sides of the scraper 311.

[0035] The working principle of the sodium-ion battery electrode coating equipment disclosed in the present application is as follows: the user connects the docking frame 1 to the conveyor belt through the docking bolts 121 on the outside of the docking frame 1, then injects the material into the storage barrel 211 with ultrasonic function, the stirring assembly 22 is in operation, and the stirring motor 221 is powered on to drive the stirring blade group 223 and the elastic scraper 224 to rotate through the stirring shaft 222 to fully stir and scrape the material. The spiral blades 225 on the stirring shaft 222 can guide the material. Under the control of the discharge valve 212, the material is discharged from the discharge port to coat the electrode. The driving cylinder 321 is started to drive the scraper 311 to move up and down along the height direction of the docking frame 1 through the telescopic rod 322 and the output rod 323. The operator adjusts the scraping height of the scraper 311 with the help of the scale 33, thereby realizing the stirring, coating and leveling functions.
