Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Example 1: Self-generating negative electrode sodium-ion battery solid electrolyte coating device, reference Figures 1 to 3 The device includes a support base 1 and a conveying box 3. The support base 1 is in contact with the ground and provides basic support for the device. The conveying box 3 provides a conveying channel for the electrolyte material. A support mechanism 2 is provided on the top of the support base 1 to provide stable support and positioning for the operation of the device. The support mechanism 2 includes two support frames 21, the bottom of which are fixedly connected to the top of the support base 1. The support base 1 provides fixation for the two support frames 21, thereby improving the load-bearing stability of the two support frames 21. A support box 22 is fixedly connected to the top of the two support frames 21, which provides a stable space for coating the battery with solid electrolyte. A support platform 23 is fixedly connected to the rear end of the top of the support base 1. The support platform 23 is mainly used to support the conveying of the battery negative electrode material to be coated. The support base 1 provides support for the support platform 23, thereby improving the load-bearing stability of the support platform 23. The conveyor box 3 has two threaded rods 4 inside. When the two threaded rods 4 rotate, they can push the solid electrolyte forward along the internal channel of the conveyor box 3 through threaded transmission, realizing quantitative delivery of electrolyte and ensuring the continuity and stability of material supply during the coating process. The top of the conveyor box 3 is equipped with an anti-blocking mechanism 5 to prevent blockage of the solid electrolyte during feeding and conveying. The support mechanism 2 has a cleaning mechanism 7 inside, used for cleaning during device operation to prevent residual electrolyte from affecting subsequent coating quality and ensuring the accuracy of the coating operation. The anti-blocking mechanism 5 includes a feed pipe 51, the bottom of which is fixedly connected to the top rear end of the conveyor box 3. The feed pipe 51 provides a guide for the solid electrolyte, and the conveyor box 3 provides support for the feed pipe 51, thereby improving the conveying stability of the feed pipe 51. The top of the conveyor box 3 is fixedly connected with two support plates 52, which provide support and guidance. The conveyor box 3 also provides fixation for two drive components 53 to enhance the stability of the drive components 53. A drive assembly 53 is fixedly connected to the top of the conveyor box 3, providing a fixation for the drive assembly 53 and thus improving its operational stability. The drive assembly 53 includes a motor 531, which is externally fixedly connected to the inside of the conveyor box 3, preventing it from shaking during operation. A drive shaft 532 is fixedly connected to the drive end of the motor 531, providing driving force for the rotation of the drive shaft 532 and ensuring its stable rotation. A turntable 54 is fixedly connected to the top of the drive assembly 53, with the top of the drive shaft 532 fixedly connected to the bottom of the turntable 54. The rotation of the drive shaft 532 drives the turntable 54 to rotate synchronously. Two fixed plates 55 are fixedly connected to the top of the turntable 54, causing the two fixed plates 55 to rotate synchronously and stably. A fixed shaft 56 is fixedly connected to the top of the conveyor box 3. The fixed shaft 56 is used to provide rotational support. The conveyor box 3 provides fixation for the fixed shaft 56, thereby improving the load-bearing capacity of the fixed shaft 56. A rotating plate 57 is rotatably connected to the outside of the fixed shaft 56. The outer surfaces of two fixed plates 55 are in contact with the outer surfaces of the rotating plate 57. When the fixed plates 55 rotate and contact the rotating plate 57, the rotation of the fixed plates 55 drives the rotating plate 57 to rotate around the fixed shaft 56. A connecting plate 58 is fixedly connected to the right end of the rotating plate 57. The rotating plate 57 is welded to the connecting plate 58, and the rotation of the rotating plate 57 drives the connecting plate 58 to rotate synchronously around the fixed shaft 56. A sliding plate 59 is slidably connected inside the two support plates 52. The interior of the two support plates 52 has grooves to guide the sliding of the sliding plate 59 and prevent it from shifting during sliding. The outside of the connecting plate 58 is rotatably connected to the interior of the sliding plate 59. The rotation of the rotating plate 57 causes the connecting plate 58 to rotate synchronously. The interior of the sliding plate 59 has grooves to support the rotation of the connecting plate 58. A limiting plate 510 is fixedly connected to the left end of the sliding plate 59. The outer surfaces of the two fixed plates 55 are in contact with the outer surfaces of the limiting plate 510. The turntable 54 drives the two fixed plates 55 to rotate, thereby impacting the limiting plate 510 and generating displacement. The movement of the limiting plate 510 causes the sliding plate 59 to slide inside the two support plates 52. A limiting shaft 511 is fixedly connected to the front end of the sliding plate 59. The outer surface of the limiting shaft 511 is slidably connected to the inside of the connecting plate 58. The rotation of the connecting plate 58 drives the limiting shaft 511 to move, thereby guiding and restricting the relative movement between the sliding plate 59 and the connecting plate 58, ensuring that the sliding plate 59 can slide smoothly. Specifically, the drive shaft 532 is driven to rotate by the starter motor 531, which in turn drives the turntable 54 to rotate, thereby causing the two fixed plates 55 to rotate. The rotation of the fixed plates 55 and their contact with the rotating plate 57 and the limiting plate 510 cause the limiting plate 510 to drive the sliding plate 59 to rotate inside the two support plates 52. At the same time, through contact with the rotating plate 57, the rotating plate 57 drives the connecting plate 58 to rotate in the opposite direction through the fixed shaft 56. In turn, the connecting plate 58 drives the limiting shaft 511 to make the sliding plate 59 slide in the opposite direction inside the two support plates 52. Through reciprocating motion, the sliding plate 59 continuously impacts the feed pipe 51, causing the feed pipe 51 to vibrate, thereby preventing material accumulation and blockage.

[0013] Reference Figure 1 , Figure 2 and Figure 4The support mechanism 2 has a support block 6 fixedly connected to its left end. The support mechanism 2 provides fixation for the support block 6, enhancing its load-bearing stability. The cleaning mechanism 7 includes a second motor 71, which is externally fixedly connected to the inside of the support block 6. The support block 6 provides support for the second motor 71, preventing it from shaking during operation and thus improving its stability. A rotating shaft 72 is fixedly connected to the drive end of the second motor 71, and a drive wheel 73 is fixedly connected to the outside of the rotating shaft 72. Starting the second motor 71 provides driving force for the rotation of the rotating shaft 72, which in turn drives the drive wheel 73 for synchronous support. Two rotating rods 74 are rotatably connected inside the support mechanism 2. The support mechanism 2 provides support for the rotation of the rotating rods 74, preventing them from deviating during rotation and improving their rotational stability. One of the rotating rods 74 is externally fixedly connected to a driven wheel 75. A belt 76 is fitted around both the driving wheel 73 and the driven wheel 75. Rotation of the driving wheel 73 drives the belt 76, which in turn drives the driven wheel 75, thus rotating one of the rotating rods 74. Both rotating rods 74 are internally slidably connected to sliding shafts 77, providing support for the sliding shafts 77 and preventing them from deviating during sliding, thereby improving the sliding stability of the sliding shafts 77. A cleaning roller 78 is externally slidably connected to the sliding shaft 77. The cleaning roller 78 performs cleaning; rotation of the sliding shaft 77 drives the cleaning roller 78, improving its cleaning efficiency. A spring 79 is fitted around the sliding shaft 77, providing support for the spring 79, ensuring even force distribution and extending its service life. The distal ends of the two springs 79 are fixedly connected to the left and right ends of the support mechanism 2, respectively. The support mechanism 2 provides support for the springs 79, thereby improving their load-bearing capacity and providing support for their reset. A fixing ring 710 is fixedly connected to the outside of the sliding shaft 77. The proximal ends of the two springs 79 are fixedly connected to the distal ends of the two fixing rings 710. By pulling the sliding shaft 77, the fixing rings 710 move and compress the springs 79, causing the springs 79 to deform under force. The springs 79 then release their elastic force, allowing the sliding shaft 77 to reset. Two connecting rods 711 are rotatably connected to the adjacent ends of the two sliding shafts 77. Limiting rods 712 are fixedly connected inside each of the connecting rods 711. The cooperation of the two connecting rods 711 and the multiple limiting rods 712 restricts and links the relative sliding of the two sliding shafts 77, thereby causing the two cleaning rollers 78 to rotate synchronously with the rotation of the sliding shafts 77. A coating roller 8 is rotatably connected inside the support mechanism 2. The coating roller 8 is used to uniformly coat the conveyed solid electrolyte onto the surface of the battery negative electrode material. A conveyor belt 9 is provided inside the support mechanism 2. The conveyor belt 9 is used to transport the battery negative electrode material to be coated to below the coating roller 8 for coating, and simultaneously transport the coated material to the next process step. Specifically, the battery negative electrode material to be coated is conveyed to the area below the coating roller 8 via conveyor belt 9. Motor 71 drives the rotating shaft 72 to rotate, which in turn rotates the coating roller 8, uniformly coating the surface of the battery negative electrode material with the solid electrolyte. Simultaneously, the rotation of the rotating shaft 72 drives the drive wheel 73, which in turn drives the belt 76, which in turn drives the driven wheel 75. The driven wheel 75 then drives the rotating rod 74 to rotate. Limiting by the connecting rod 711 and the limiting rod 712, the rotating rod 74 drives the cleaning roller 78 to rotate, thereby... The conveyor belt 9 is used for cleaning to prevent solid electrolyte residue. When the cleaning roller 78 needs to be replaced, the sliding shaft 77 is pulled, causing the two limiting rods 712 to rotate and slide away from the interior of the cleaning roller 78. At this time, the sliding shaft 77 causes the fixing ring 710 to compress the spring 79 and deform. When the cleaning roller 78 is placed, the spring 79 releases the elastic force to drive the sliding shaft 77 to embed into the interior of the cleaning roller 78. At the same time, the two limiting rods 712 continuously unfold, and the spring 79 keeps the limiting rods 712 tightly attached to the interior of the cleaning roller 78, thereby completing the rapid replacement of the cleaning roller 78 and improving the cleaning efficiency of the cleaning roller 78.

[0014] The implementation principle of this embodiment is as follows: Material enters the feed pipe 51. At this time, the starter motor 531 drives the drive shaft 532 to rotate. The rotation of the drive shaft 532 drives the turntable 54 to rotate, which in turn drives the fixed plate 55 to rotate. The fixed plate 55 contacts the limiting plate 510, causing the limiting plate 510 to drive the sliding plate 59 to slide inside the support plate 52. Simultaneously, the fixed plate 55 contacts the rotating plate 57, causing the rotating plate 57 to rotate around the fixed shaft 56, thereby driving the connecting plate 58 to rotate. The connecting plate 58 is connected to the limiting shaft 51. 1. The sliding plate 59 is driven to rotate in the opposite direction, thereby forming repeated movement of the sliding plate 59 against the feed pipe 51. This causes the sliding plate 59 to continuously hit the feed pipe 51, causing the feed pipe 51 to vibrate, thus preventing material accumulation and blockage. The solid electrolyte is then transported through two threaded rods 4. When the solid electrolyte is transported to the coating roller 8, the conveyor belt 9 transports the battery negative electrode material to be coated to the bottom of the coating roller 8. The starting motor 71 drives the rotating shaft 72 to rotate, thereby driving the coating roller 8 to rotate, so that the coating roller 8 can evenly coat the transported solid electrolyte onto the surface of the battery negative electrode material. Simultaneously, the rotation of the rotating shaft 72 drives the drive wheel 73 to rotate, which in turn drives the belt 76 to rotate. The rotation of the belt 76 drives the driven wheel 75 to rotate, which in turn drives the rotating rod 74 to rotate, which in turn drives the sliding shaft 77 to rotate, thereby driving the cleaning roller 78 to rotate. This is used to clean the residue on the surface of the conveyor belt 9. When the cleaning roller 78 needs to be disassembled, the sliding shaft 77 is manually pulled to slide away from the interior of the cleaning roller 78, and then the cleaning roller 78 is replaced. At this time, the sliding shaft 77 drives the fixing ring 710 to slide inside the rotating rod 74 and compresses the spring 79, causing the spring 79 to deform under force. When installing the cleaning roller 78, the spring 79 releases its elasticity, allowing the sliding shaft 77 to embed into the interior of the cleaning roller 78, thereby driving the two limit rods 712 to press tightly against the interior of the cleaning roller 78, thus completing the fixation and restriction of the cleaning roller 78. By quickly replacing the cleaning roller 78, the cleaning efficiency of the cleaning roller 78 is improved, the residue on the surface of the conveyor belt 9 is reduced, and the production efficiency is improved.
