Description
Technical Field
[0001] This utility model belongs to the field of coating machine technology, and in particular relates to a precision coating machine for sulfide solid-state batteries. Background Technology
[0002] As a novel battery technology, sulfide solid-state batteries possess significant advantages such as high energy density, good safety, and long cycle life, and are considered one of the most promising next-generation battery technologies. They are expected to be widely used in electric vehicles, energy storage systems, and other fields, thereby driving the research and development and demand for their production equipment. In the battery manufacturing process, electrode coating is a key step that directly affects the battery's performance and quality. For sulfide solid-state batteries, the characteristics of their electrode materials and the quality of coating play a decisive role in the battery's electrochemical performance, charge and discharge efficiency, and cycle life.
[0003] However, during the use of existing precision coating machines for sulfide solid-state batteries, the carrier is prone to instability such as shaking and displacement, which causes changes in the distance and angle between the coating head and the carrier, resulting in uneven coating thickness of the slurry and thus reducing the overall performance and quality of the battery. Utility Model Content
[0004] The purpose of this invention is to provide a precision coating machine for sulfide solid-state batteries. By setting up a clamping mechanism, it solves the problem that in existing precision coating machines for sulfide solid-state batteries, the carrier is prone to shaking and displacement during use, which causes changes in the distance and angle between the coating head and the carrier, resulting in uneven coating thickness and thus reducing the overall performance and quality of the battery.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a precision coating machine for sulfide solid-state batteries, including a worktable, on which two clamping mechanisms and a coating mechanism are provided;
[0007] The worktable is equipped with a clamping mechanism and a coating mechanism. The clamping mechanism includes two slide rods fixedly connected to the top of the worktable. A clamping plate is slidably connected to the outer wall of the two slide rods. A support plate is fixedly connected to the top of the two slide rods. A gasket is fixedly connected to the bottom of the clamping plate. A spring is sleeved on the outer wall of each of the two slide rods. The bottom of each spring is fixedly connected to the clamping plate. The top of each spring is fixedly connected to the support plate. A pull rod is fixedly connected to the top of the clamping plate. The top of the pull rod slides through the support plate and extends to the outside.
[0008] Furthermore, the coating mechanism includes a moving component and a coating component. The moving component includes a connecting plate fixedly connected between two support plates. An electric telescopic rod is fixedly connected to the top of the connecting plate, and the bottom of the electric telescopic rod slides through the connecting plate.
[0009] Furthermore, an H-shaped support frame is fixedly connected to the output shaft of the connecting plate, and two L-shaped support plates are fixedly connected to the bottom of the H-shaped support frame.
[0010] Furthermore, threaded rods are rotatably connected to the front and rear inner walls of the L-shaped support plate located on the left side, the front side of the threaded rods rotatably extending to the L-shaped support plate located on the left side, and a movable plate is threadedly connected to the outer wall of the threaded rods.
[0011] Furthermore, two limiting plates are fixedly connected to the sides of the two support plates that are close to each other, and several limiting rods are fixedly connected to the top of the H-shaped support frame, with the tops of the several limiting rods sliding through the several limiting plates respectively.
[0012] Furthermore, the coating assembly includes a slide rod fixedly connected to the inner walls of the front and rear sides of the right-side L-shaped support plate. The slide rod slides through the moving plate. A motor is fixedly connected to the front side of the left-side L-shaped support plate, and the output shaft of the motor is fixedly connected to the slide rod via a coupling.
[0013] Furthermore, a sprayer is fixedly connected to the rear side of the movable plate, the sprayer being filled with battery slurry, and a scraper is fixedly connected to the front side of the movable plate.
[0014] This utility model has the following beneficial effects:
[0015] 1. By setting up a clamping mechanism, when coating is required, the pull rod can be pulled to move the pull rod upward, thereby moving the clamping plate and the gasket upward. At this time, the spring will also be compressed as the clamping plate moves upward. When the spring is compressed, it will undergo elastic deformation and generate elastic force. After being pulled to the appropriate position, the carrier to be coated is placed on the worktable, and then the pull rod is released. At this time, the clamping plate will move downward under the action of the spring force, and the carrier to be coated is fixed on the worktable by the gasket. This can effectively prevent the carrier from shaking, shifting or loosening during the coating process, ensuring the accuracy and quality of coating. Moreover, the spring can automatically adjust the elastic force and the position of the clamping plate according to the actual situation, ensuring a good fixing effect for various carriers.
[0016] 2. By setting up a coating mechanism, after the carrier is fixed, the motor can be started. The motor drives the threaded rod to rotate. When the threaded rod rotates, the moving plate will also move backward under the action of the sliding rod, thereby moving the moving plate backward. When it moves to the required coating position, the electric telescopic rod can be activated according to the required coating thickness. The electric telescopic rod drives the sprayer and scraper downward through the H-shaped support frame until the scraper moves to the corresponding position. Then the sprayer is turned on, and the sprayer sprays the battery paste onto the carrier. The paste is then scraped flat by the scraper, which can avoid paste accumulation or uneven coating, improve the paste utilization rate, reduce material waste, lower production costs, reduce porosity and defects in the coating, improve the adhesion between the coating and the carrier, and thus improve the overall quality and performance of the battery.

A pull rod 206 is fixedly connected to the top of the clamping plate 202. The top of the pull rod 206 slides through the support plate 203 and extends to the outside. By setting the clamping mechanism 2, it is possible to effectively prevent the carrier from shaking, shifting or loosening during the coating process, thus ensuring the accuracy and quality of the coating. Moreover, the springs 205 can automatically adjust the elastic force and the position of the clamping plate according to the actual situation, ensuring that a good fixing effect can be achieved for various carriers.
[0028] The coating mechanism 3 includes a moving component 31 and a coating component 32. The moving component 31 includes a connecting plate 311 fixedly connected between two support plates 203.

After the carrier is fixed in place... The motor 322 can be started, which drives the threaded rod 315 to rotate. When the threaded rod 315 rotates, the moving plate 316 will also move backward under the action of the slide rod 321, thereby driving the moving plate 316 to move backward. When it moves to the position to be coated, the electric telescopic rod 312 can be started according to the required coating thickness. The electric telescopic rod 312 drives the sprayer 323 and the scraper 324 to move downward through the H-shaped support frame 313 until the scraper 324 moves to the corresponding position. Then the sprayer 323 is turned on, and the sprayer 323 sprays the battery paste onto the carrier. The paste will be scraped flat by the scraper 324.
