Description

Technical Field

[0001] This utility model belongs to the field of solid-state battery processing technology, and in particular relates to a coating device for lithium-tin-phosphorus-sulfur solid-state batteries. Background Technology

[0002] With the booming development of the new energy industry, higher requirements are being placed on battery performance. Lithium-tin-phosphorus-sulfur solid-state batteries have become a research hotspot and development direction due to their advantages such as high energy density and good safety. In the production process, the coating process has a key impact on battery performance. Precise coating can stabilize the electrode-electrolyte interface, promote ion transport and suppress side reactions. However, existing coating technologies have problems such as poor precision, poor material adaptability and low production efficiency, which make it difficult to meet the needs of large-scale and high-quality production of lithium-tin-phosphorus-sulfur solid-state batteries. Developing new and efficient coating devices is of great significance to promoting the industrialization of lithium-tin-phosphorus-sulfur solid-state batteries.

[0003] However, the existing coating devices for lithium-tin-phosphorus-sulfur solid-state batteries are not easy to coat the electrolyte material evenly during use, resulting in inconsistent contact area and contact effect between the electrode and the electrolyte. This leads to substandard battery quality, a decrease in product qualification rate, and increased production costs and resource waste. Utility Model Content

[0004] The purpose of this invention is to provide a coating device for lithium-tin-phosphorus-sulfur solid-state batteries. By setting up a uniform distribution mechanism, it solves the problem that existing coating devices for lithium-tin-phosphorus-sulfur solid-state batteries are not easy to uniformly coat electrolyte materials during use, resulting in inconsistent contact area and contact effect between the electrode and the electrolyte, which leads to substandard battery quality, reduced product qualification rate, increased production costs and waste of resources.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a coating device for lithium-tin-phosphorus-sulfur solid batteries, which includes two supports, and the supports are provided with a uniform distribution mechanism and a stirring mechanism.

[0007] A second support is fixedly connected to the top of the two first supports. A conveying assembly is provided between the two first supports. A housing is fixedly connected between the two first supports. A diversion pipe is provided at the top of the housing. Two limiting blocks are fixedly connected to the top of the inner wall of the housing. A rotating shaft is rotatably connected to the inner wall of the housing. Three third blocks are fixedly connected to the outer wall of the rotating shaft. The outer walls of the three third blocks are in contact with the inner walls of the two limiting blocks. The stirring mechanism includes a material bucket fixedly connected to the inner wall of the second support. The bottom of the material bucket is connected to the diversion pipe.

[0008] Furthermore, a second rotating shaft is rotatably connected to the inner wall of the outer shell, a coating block is fixedly connected to the outer wall of the second rotating shaft, and a coating plate is fixedly connected to the inner wall of the outer shell.

[0009] Furthermore, a motor bracket is fixedly connected to the top of the front bracket, and a motor is fixedly connected to the inner wall of the motor bracket. The output shaft of the motor is fixedly connected to the rotating shaft via a coupling.

[0010] Furthermore, two pulleys are provided on the front side of the outer casing. The inner wall of the pulley on the right side is fixedly connected to a rotating shaft one, and the inner wall of the pulley on the left side is fixedly connected to a rotating shaft two. A belt is fitted on the two pulleys.

[0011] Furthermore, a lid is fixedly connected to the inner wall of the material bucket, a door is hinged to the left side of the lid, a second motor is fixedly connected to the top of the lid, a third rotating shaft is rotatably connected to the inner wall of the lid, and the output shaft of the second motor is fixedly connected to the third rotating shaft via a coupling.

[0012] Furthermore, a number of stirring paddles are fixedly connected to the outer wall of the rotating shaft three, a connecting block one is fixedly connected to the outer wall of the rotating shaft three, and a number of scrapers are fixedly connected to the outer wall of the connecting block one. The side of each of the scrapers away from the rotating shaft three is in contact with the material bucket.

[0013] Furthermore, a filter plate is slidably connected to the inner wall of the material barrel, and several spring telescopic rods are fixedly connected to the bottom of the filter plate. The bottom of each spring telescopic rod is fixedly connected to the material barrel, and several protrusions are fixedly connected to the top of the filter plate.

[0014] Furthermore, a connecting block two is fixedly connected to the outer wall of the rotating shaft three, a connecting shaft is fixedly connected to the inner wall of the connecting block two, a cross block is fixedly connected to the outer wall of the connecting shaft, the cross block is adapted to several protrusions, and the outer wall of the cross block is in contact with the inner wall of the material barrel.

[0015] This utility model has the following beneficial effects:

[0016] 1. By setting up a distribution mechanism, when the electrolyte falls into the distribution pipe, it will continue to fall into the space formed between the two limit blocks and the three blocks. At this time, motor one can be started to rotate its output shaft, which will drive shaft one to rotate. When shaft one rotates, it will drive the three blocks to rotate, thus bringing these electrolytes into the outer shell and then onto the battery container on the conveying assembly. When shaft one rotates, it will drive the coating block to rotate through shaft two under the action of the pulley and belt, thereby dispersing the electrolyte that has fallen onto the battery container and making it more evenly distributed. Then the conveying assembly continues to run. When the coated battery container passes through the bottom of the coating plate, the electrolyte layer will be leveled by the action of the coating plate, so that the electrolyte can be evenly discharged when coating, so that the amount of electrolyte material coated in the same time interval is the same, and the electrolyte material can be evenly coated, thus ensuring that the product quality will not decrease due to uneven coating.

[0017] 2. By setting up a stirring mechanism, the battery container is moved from right to left into the device. Then, the cover is opened, and the battery electrolyte is poured into the material tank. At this time, motor two can be started, causing its output shaft to rotate, which in turn drives shaft three to rotate. The rotation of shaft three will drive the stirring paddle to stir the electrolyte in the material tank, preventing it from clumping. At the same time, the rotation of shaft three will drive the scraper to rotate around shaft three through connecting block one, thereby scraping the inner wall of the material tank. The rotation of shaft three will also drive the cross block to rotate through connecting block two and connecting shaft. The filter plate will slide downward under the action of the cross block and the protrusion. At this time, the filter plate will apply pressure to the spring telescopic rod, causing it to undergo elastic deformation and generate elastic force. This elastic force will cause the filter plate to return to its original position, thereby achieving vibration. Under the action of this vibration, the electrolyte in the material tank falls into the diversion pipe, which can stir the raw materials in the material tank, preventing them from accumulating and clumping, and clogging the device. At the same time, the raw materials are screened before discharge, and unqualified raw materials are removed. Qualified raw materials are transported and coated, thereby further ensuring the quality of the product.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] Please see Figure 1-6As shown, this utility model is a coating device for a lithium-tin-phosphorus-sulfur solid-state battery, including two supports 1.

A belt 212 is fitted on the two pulleys 211. By setting the equalizing mechanism 2, the electrolyte can be evenly discharged during coating, so that the amount of electrolyte material coated within the same time interval is the same. At the same time, the electrolyte material can be evenly coated, thereby ensuring that the product quality will not decrease due to uneven coating.

[0030] The stirring mechanism 3 includes a material bucket 301 fixedly connected to the inner wall of the support frame 2 101. The bottom of the material bucket 301 is connected to the diversion pipe 202. A bucket cover 302 is fixedly connected to the inner wall of the material bucket 301. A cover door 303 is hinged to the left side of the bucket cover 302. A motor 2 304 is fixedly connected to the top of the bucket cover 302. A rotating shaft 305 is rotatably connected to the inner wall of the bucket cover 302. The output shaft of the motor 2 304 is fixedly connected to the rotating shaft 305 via a coupling. Several stirring paddles 306 are fixedly connected to the outer wall of the rotating shaft 305. A connecting block 1 307 is fixedly connected to the outer wall of the rotating shaft 305. Several scrapers 308 are fixedly connected to the outer wall of the connecting block 1 307. The side of each scraper 308 away from the rotating shaft 305 is in contact with the material bucket 301. A filter plate 309 is slidably connected to the inner wall of the material bucket 301. The bottom of the filter plate 309 is fixedly connected to several spring telescopic rods 310, and the bottom of each spring telescopic rod 310 is fixedly connected to the material barrel 301. The top of the filter plate 309 is fixedly connected to several protrusions 311. The outer wall of the rotating shaft 305 is fixedly connected to the connecting block 2 312, and the inner wall of the connecting block 2 312 is fixedly connected to the connecting shaft 313.

The outer wall of the cross block 314 is in contact with the inner wall of the material barrel 301. By setting the stirring mechanism 3, the raw materials in the material barrel can be stirred to prevent them from accumulating and clumping, thus preventing blockage of the device. At the same time, the raw materials are screened before discharge to remove unqualified raw materials and transport qualified raw materials for coating, thereby further ensuring the quality of the product.

[0031] A specific application of this embodiment is as follows: During use, the battery container (which is aluminum foil) is placed above the conveying assembly 102. The conveying assembly 102 is then activated, causing the battery container to move from right to left into the device. The cover door 303 is then opened, and the battery electrolyte (a lithium-tin-phosphorus-sulfur solid electrolyte in white powder form) is poured into the container 301. At this point, motor 2 304 can be activated, causing its output shaft to rotate, which in turn drives shaft 305 to rotate. The rotation of shaft 305 will... The rotating impeller 306 stirs the electrolyte in the material tank 301 to prevent it from clumping. Simultaneously, the rotation of the rotating shaft 305 drives the scraper 308 to rotate around the shaft 305 via the connecting block 307, thus scraping the inner wall of the material tank 301. Furthermore, the rotation of the rotating shaft 305 also drives the cross block 314 to rotate via the connecting block 312 and the connecting shaft 313. The filter plate 309 slides downwards under the action of the cross block 314 and the protrusion 311. At this time, the filter plate 309 will interact with the spring telescopic rod 31. Applying pressure causes elastic deformation and generates elastic force, which resets the filter plate 309, thus causing vibration. Under this vibration, the electrolyte in the feed hopper 301 falls into the diversion pipe 202. When the electrolyte falls into the diversion pipe 202, it continues to fall into the space formed between the two limiting blocks 203 and the three-part block 205. At this time, the motor 210 can be started, causing its output shaft to rotate, which in turn drives the rotating shaft 204 to rotate. When the rotating shaft 204 rotates, it drives the three-part block 205 to rotate. This brings the electrolytes into the housing 201 and onto the battery container on the conveying assembly 102. When the first rotating shaft 204 rotates, it drives the coating block 207 to rotate through the second rotating shaft 206 under the action of the pulley 211 and the belt 212, thereby dispersing the electrolytes that have fallen onto the battery container and making them more evenly distributed. Then the conveying assembly 102 continues to run. When the coated battery container passes through the bottom of the coating plate 208, the electrolyte layer is smoothed by the action of the coating plate 208.
