Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic spraying, in particular to an ultrasonic spraying device for lithium battery negative electrode materials. Background Art

[0002] With the rise of electric vehicles, the research and development of lithium battery technology has also received increasing attention. Among them, the research on negative electrode materials is particularly important because it directly affects the performance and life of the battery. At present, the most commonly used negative electrode material on the market is graphite, but with the popularity of electric vehicles, the performance of graphite can no longer meet market demand. Therefore, people began to research and develop new negative electrode materials, among which carbon silicon material is considered to be the most promising one. Carbon silicon material is a natural material composed of carbon and silicon, which is more environmentally friendly than materials such as graphite.

[0003] In the prior art, most of the silicon nitride is coated on the surface of the pole piece by ultrasonic spraying. Compared with the conventional hot solvent or chemical vapor deposition production method, ultrasonic spraying technology has the advantages of high efficiency, low cost, and environmental protection. However, the existing ultrasonic spraying device can only spray a single pole piece, which is inefficient. Utility Model Content

[0004] The utility model aims to provide an ultrasonic spraying device for lithium battery negative electrode material, which has a simple structure and effectively improves the spraying efficiency of the ultrasonic spraying device.

[0005] A lithium battery negative electrode material ultrasonic spraying device comprises a rotating disk, a rotating driving member, and a spraying station, wherein the rotating disk is connected to the rotating driving member, and the rotating driving member can drive the rotating disk to rotate. The rotating disk has a plurality of clamps arranged at equal angles along its circumference, and the spraying station is arranged in the rotation path of the rotating disk, and the clamps comprise a mounting seat and a support plate, wherein the mounting seat is arranged on the rotating disk, and the support plate is movably connected to the mounting seat.

[0006] In the above technical solution, a number of clamps are arranged on the rotating disk, and the clamps include a mounting seat and a support plate, and the electrode sheet is arranged on the support plate. When the clamps are rotated to the spraying station, the spraying station sprays the electrode sheet arranged on the support plate. The rotating disk and the spraying station cooperate with each other. Compared with the prior art, the utility model can continuously spray multiple electrode sheets, thereby improving the spraying efficiency.

[0007] Furthermore, the spraying station includes a driving component, an ultrasonic atomizing nozzle, and a supporting seat, the driving component is arranged on the supporting seat, the ultrasonic atomizing nozzle is arranged on the driving component, and the driving component drives the ultrasonic atomizing nozzle to move horizontally.

[0008] In the above technical solution, when the fixture reaches the spraying station, the ultrasonic atomizing nozzle moves horizontally under the action of the driving component to evenly spray the electrode sheet, thereby improving the spraying effect.

[0009] Furthermore, the spraying station also includes a lifting drive component, which is opposite to the support seat. When the clamp reaches the spraying station, the lifting drive component drives the support plate to move vertically.

[0010] In the above technical solution, in order to better improve the spraying effect, when the fixture reaches the spraying station, the lifting drive member drives the support plate to move upward, so that the electrode sheet is close to the ultrasonic atomizing nozzle, further improving the spraying effect.

[0011] Furthermore, the support plate is a heating element.

[0012] In the above technical solution, placing the support plate on the heating plate can make the coating cover the surface of the electrode sheet more quickly, thereby improving the spraying quality.

[0013] Furthermore, the mounting seat is provided with a positioning groove, and the support plate is arranged in the positioning groove.

[0014] In the above technical solution, the positioning groove is used to place the support plate to prevent the rotating disk from throwing the electrode sheet off the support plate during rotation, thereby causing damage to the electrode sheet.

[0015] Furthermore, the size of the support plate is smaller than the size of the positioning groove.

[0016] In the above technical solution, when the supporting plate is lifted vertically, the size of the supporting plate is smaller than the size of the positioning groove, which can effectively avoid the groove wall of the positioning groove from contacting the electrode sheet, thereby preventing the electrode sheet from being scratched.

[0017] Furthermore, the positioning groove is provided with a through hole, and the support plate cover is arranged on the through hole.

[0018] In the above technical solution, when the fixture rotates to the spraying station, the lifting drive can drive the pallet to rise through the through hole. On the one hand, it makes the electrode sheet close to the ultrasonic atomizing nozzle, so that the ultrasonic atomizing nozzle can better spray the electrode sheet and improve the spraying effect. On the other hand, it enables the staff to better take out or place the electrode sheet on the pallet.

[0019] Furthermore, a plurality of guide posts are provided on one side of the support plate facing the positioning groove, and the positioning groove is provided with guide holes matching the guide posts, and the support plate is vertically lifted and lowered along the guide holes through the guide posts.

[0020] In the above technical solution, the guide column has a guiding function. When the lifting drive member drives the pallet to rise, the guide hole guides the pallet through the guide column to prevent the pallet from deviating during the movement, thereby affecting the spraying effect.

[0021] Furthermore, there are four guide posts, which are respectively arranged at the corners of the support plate.

[0022] In the above technical solution, guide posts are provided at the four corners of the support plate for better guidance, thereby further avoiding deviation of the support plate.

[0023] Compared with the prior art, the beneficial effect of the utility model is that by arranging a rotating disk and a spraying station, the rotating disk and the spraying station cooperate with each other, and a plurality of pole pieces are sprayed continuously, thereby improving work efficiency.

DETAILED DESCRIPTION

[0029] The following will further describe the ultrasonic spraying device for lithium battery negative electrode material of the utility model in detail with reference to specific embodiments and drawings. The drawings show preferred embodiments of the utility model. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0030] Please refer to Figure 1In a preferred embodiment, the ultrasonic spraying device for lithium battery negative electrode material of the utility model includes a rotating disk 1, a rotating driving member 2, and a spraying station 3. The rotating disk 1 is connected to the rotating driving member 2, and the rotating driving member 2 can drive the rotating disk 1 to rotate. The rotating disk 1 has a plurality of clamps 4 arranged at equal angles along its circumference. The spraying station 3 is arranged on the rotating path of the rotating disk 1. The clamp 4 includes a mounting seat 401 and a support plate 402. The mounting seat 401 is arranged on the rotating disk 1, and the support plate 402 is movably connected to the mounting seat 401.

[0031] It can be seen from the above technical solution that by arranging a number of clamps 4 on the rotating disk 1, the clamps 4 include a mounting seat 401 and a support plate 402, and the electrode sheet is arranged on the support plate 402. When the clamps 4 are rotated to the spraying station 3, the spraying station 3 sprays the electrode sheet arranged on the support plate 402, and the rotating disk 1 and the spraying station 3 cooperate with each other. Compared with the prior art, the utility model can continuously spray multiple electrode sheets, thereby improving the spraying efficiency.

[0032] Specifically, the utility model is provided with four clamps 4, each of which includes a mounting seat 401 and a support plate 402, and each support plate 402 can be placed with one electrode sheet. As another embodiment, the number of the clamps 4 can be 6, 8, 10, etc.

[0033] Please refer to Figure 1 The spraying station 3 includes a driving assembly 301, an ultrasonic atomizing nozzle 302, and a support seat 303. The driving assembly 301 is arranged on the support seat 303, and the ultrasonic atomizing nozzle 302 is arranged on the driving assembly 301. The driving assembly 301 drives the ultrasonic atomizing nozzle 302 to move horizontally. When the fixture 4 arrives at the spraying station 3, the ultrasonic atomizing nozzle 302 moves horizontally under the action of the driving assembly 301, and the electrode sheet is sprayed evenly to improve the spraying effect. Exemplarily, in the utility model, the driving assembly 301 includes a guide rail and a slider, the ultrasonic atomizing assembly is connected to the slider, and the slider is slidably connected to the guide rail. When the fixture 4 arrives at the spraying station 3, the ultrasonic atomizing nozzle 302 moves horizontally in the direction of the electrode sheet driven by the slider, thereby spraying the electrode sheet.

[0034] Furthermore, in order to better improve the spraying effect, the spraying station 3 also includes a lifting drive 304, which is opposite to the support seat 303. When the fixture 4 reaches the spraying station 3, the lifting drive 304 drives the support plate 402 to move vertically. The lifting drive 304 drives the support plate 402 to move upward, so that the electrode sheet is close to the ultrasonic atomizing nozzle 302, reducing the vertical distance between the electrode sheet and the ultrasonic atomizing nozzle 302, and further improving the spraying effect.

[0035] It should be noted that the support plate 402 is a heating element. Placing the support plate 402 on the heating plate can make the coating cover the surface of the electrode sheet more quickly, thereby improving the spraying quality. In specific implementation, the temperature of the heating plate can be controlled by the control unit. As a preferred embodiment, when spraying the electrode sheet, the temperature of the heating plate is set to 100°C.

[0036] Please refer to Figure 3 The mounting seat 401 is provided with a positioning groove 4011, and the support plate 402 is arranged in the positioning groove 4011. The positioning groove 4011 is used to place the support plate 402 to prevent the rotating disk 1 from throwing the electrode sheet off the support plate 402 during the rotation process, thereby causing damage to the electrode sheet. Specifically, the lifting drive member 304 drives the support plate 402 to move upward and extend out of the positioning groove 4011, so that the staff can place the electrode sheet to be sprayed on the support plate 402, and then press the support plate 402 downward to extend the support plate 402 into the positioning groove 4011.

[0037] It should be noted that the size of the support plate 402 is smaller than the size of the positioning groove 4011. Since the support plate 402 is used to place the electrode sheet, and the support plate 402 is arranged in the positioning groove 4011, when the support plate 402 is vertically raised or lowered, the size of the support plate 402 is smaller than the size of the positioning groove 4011, which can well avoid the groove wall of the positioning groove 4011 from contacting the electrode sheet, thereby preventing the electrode sheet from being scratched.

[0038] In addition, the positioning groove 4011 is provided with a through hole 4011a, and the support plate 402 is covered on the through hole 4011a. When the fixture 4 rotates to the spraying station 3, the lifting drive member 304 can drive the support plate 402 to rise through the through hole 4011a, which, on the one hand, makes the electrode sheet close to the ultrasonic atomizing nozzle 302, so that the ultrasonic atomizing nozzle 302 can better spray the electrode sheet and improve the spraying effect, and on the other hand, it makes it easier for the staff to take out or place the electrode sheet on the support plate.

[0039] Further, a side of the support plate 402 facing the positioning groove 4011 is provided with a plurality of guide posts 4021, and the positioning groove 4011 is provided with a guide hole 4011b matching the guide post 4021, and the support plate 402 is vertically lifted and lowered along the guide hole 4011b through the guide post 4021. The guide post 4021 has a guiding function, and when the lifting drive member 304 drives the support plate 402 to rise, the guide hole 4011b guides the support plate 402 through the guide post 4021, so as to avoid the deviation of the support plate 402 during the movement, thereby affecting the spraying effect. Exemplarily, there are four guide posts 4021, and the guide posts 4021 are respectively arranged at the corners of the support plate 402. The four corners of the support plate 402 are provided with guide posts 4021, which can better guide and further avoid the deviation of the support plate 402.

[0040] In summary, the utility model provides an ultrasonic spraying device for lithium battery negative electrode materials, which can realize continuous spraying of multiple electrode sheets and improve the spraying efficiency.
