Description

Technical Field

[0001] This application relates to the field of powder preparation technology, specifically to a powder preparation apparatus. Background Technology

[0002] In the battery material production process, to improve the temperature and sintering atmosphere uniformity of the materials in the furnace, the materials in the crucible are usually cut into pieces before being fed into the furnace. This increases the contact area between the materials and the atmosphere, thereby ensuring more complete sintering and more uniform contact with the sintering atmosphere. Currently, the conventional method for cutting battery materials (such as cathode materials) in production is to first shake or compact the materials, and then cut them into pieces, assemble them, and feed them into the furnace.

[0003] However, it is difficult to maintain the state of the cut blocks after cutting in this way. During the crucible transportation and assembly process, the blocks are very easy to collapse due to vibration, which has a limited effect on improving the performance of subsequent sintered materials. Utility Model Content

[0006] This application utilizes a compaction device and a cutting device arranged sequentially. By compacting the powder before cutting it into blocks, material flow is reduced, and the surface smoothness of the material is improved. This reduces material volatilization, resulting in a denser and more stable powder structure. This ensures a more uniform contact atmosphere within the kiln, promoting a more complete sintering reaction. Therefore, the pre-compacted powder exhibits better uniformity and consistency during sintering, improving the quality and performance of the final product.

The pressure head is provided with an exhaust port, which is configured to discharge gas during the compaction process.

[0009] In some embodiments of this application, the pressure head includes a first surface opposite to the carrier and a second surface away from the carrier. The pressure head is provided with a groove recessed from the first surface toward the second surface, and an exhaust port is provided on the bottom surface of the groove. The exhaust port and the groove form an exhaust channel for gas to be discharged.

[0010] In some embodiments of this application, multiple grooves are provided, and multiple groove arrays are distributed on the first surface.

[0013] In some embodiments of this application, the powder preparation apparatus further includes a conveying mechanism. The conveying mechanism is mounted on a frame and is used to transport the carrier between a compaction position and a cutting position, wherein the compaction device and the cutting device are located at the compaction position and the cutting position, respectively.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

When a component is considered to be "located" on another component, it can be directly located on the other component or may also have a component that is centrally located.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Please see Figures 1 to 3 This application provides a powder preparation apparatus, including a compaction device 1 and a cutting device 5 arranged sequentially. The compaction device 1 is used to compact the powder. The cutting device 5 is used to cut the compacted powder into pieces.

[0025] This application utilizes a compaction device 1 and a cutting device 5 arranged sequentially to compact the powder before cutting it into blocks. This reduces material flow and improves the surface smoothness of the material. By reducing material volatilization, the compacted powder has a denser and more stable structure, ensuring a more uniform contact atmosphere within the kiln and promoting a more complete sintering reaction. Therefore, the pre-compacted powder exhibits better uniformity and consistency during sintering, improving the quality and performance of the final product.

[0026] Please see Figure 1 In some embodiments of this application, the compaction device 1 includes a frame 10, a carrier 2, and a compaction mechanism 100. The carrier 2 is mounted on the frame 10 and is used to carry the powder. The compaction mechanism 100 is mounted on the frame 10 and located above the carrier 2, and is used to compact the powder on the carrier 2. By compacting the powder before cutting it into blocks, material flow can be reduced and the surface smoothness of the material can be improved. Reducing material volatilization results in a more compact and stable powder structure, ensuring a more uniform contact atmosphere within the kiln and promoting a more complete sintering reaction. Therefore, the pre-compacted powder exhibits better uniformity and consistency during sintering, improving the quality and performance of the final product.

[0027] Please see Figure 1 and Figure 2 In some embodiments of this application, the compaction mechanism 100 includes a drive mechanism 110 and a pressure head 120. The drive mechanism 110 is mounted on the frame 10 and configured to drive the pressure head 120 to move towards the carrier 2 and compact the powder. The pressure head 120 is provided with an exhaust port 130, which is configured to discharge gas generated during the compaction process. The drive mechanism 110 can precisely control the movement direction and pressure of the pressure head 120, ensuring the stability and consistency of the compaction process. Simultaneously, the exhaust port 130 effectively discharges gas generated during the compaction process, reducing uneven compaction caused by gas retention in the powder. This not only improves the working efficiency of the compaction device 1 but also reduces dust spillage caused by excessive pressure during compaction, ensuring the uniformity and stability of the powder, thus laying a good foundation for subsequent cutting and sintering processes. Optionally, the drive mechanism 110 can be a stepper motor.

[0028] Please see Figure 1 and Figure 2 In some embodiments of this application, the pressure head 120 includes a first surface 121 opposite to the carrier 2 and a second surface 122 away from the carrier 2. The pressure head 120 is provided with a groove 140 recessed from the first surface 121 toward the second surface 122. An exhaust port 130 is provided on the bottom surface of the groove 140, and the exhaust port 130 and the groove 140 form an exhaust channel for gas discharge. By providing the groove 140 and the exhaust port 130 on the pressure head 120, the gas discharge path during the compaction process is further optimized. The groove 140 can help the powder to be distributed more evenly during the compaction process, reducing the density difference caused by uneven compaction. At the same time, the combination of the exhaust port 130 and the groove 140 can discharge the gas generated during the compaction process more efficiently, reducing the interference of gas on the compaction of the powder, thereby improving the uniformity and stability of compaction. This design effectively solves the problem of poor gas discharge in traditional compaction methods and significantly improves the compaction effect of powder.

[0029] Please see Figure 2 In some embodiments of this application, multiple grooves 140 are provided, and the multiple grooves 140 are arrayed on the first surface 121. By providing multiple grooves 140, the efficiency of venting can be further improved, and the compaction effect of the powder can be enhanced. The array distribution of multiple grooves 140 allows the powder to be subjected to force more evenly during the compaction process, the venting is more uniform, and the interference of gas on the powder is reduced, thereby improving the integrity and uniformity of the powder.

[0030] Please see Figure 2In some embodiments of this application, the groove 140 is a hexagonal groove 140.

[0031] Please see Figure 2 In some embodiments of this application, a plurality of vent holes 130 are provided on the bottom surface of a groove 140, and the plurality of vent holes 130 are spaced apart within the groove 140. By providing a plurality of vent holes 130, the gas emission efficiency during the compaction process can be improved, ensuring that the gas during the compaction process can be discharged quickly and evenly, thereby reducing the interference of gas on the compaction of powder. The spaced vent holes 130 can make the gas evenly discharged on the entire surface of the press head 120, avoiding the phenomenon of uneven compaction caused by excessive accumulation of gas in a certain area. At the same time, the configuration of a plurality of vent holes 130 can also improve the durability and stability of the compaction device 1, reduce the clogging problem of the vent holes 130 due to long-term use, thereby ensuring the continuity of the compaction process.

[0032] Please see Figure 3 In some embodiments of this application, the powder preparation apparatus further includes a conveying mechanism 3. The conveying mechanism 3 is mounted on the frame 10 and is used to transport the carrier 2 between the compaction position 11 and the cutting position 50, where the compaction device 1 and the cutting device 5 are located at the compaction position 11 and the cutting position 50, respectively. The conveying mechanism 3 enables efficient transport of the carrier 2; preferably, the conveying mechanism 3 can be a conveyor belt.

[0033] Please see Figure 3 In some embodiments of this application, the conveying mechanism 3 is used to sequentially transport the carrier 2 to the compaction position 40, the compaction position 11, and the cutting position 50. The powder preparation device also includes a compaction device 4, which is mounted on the frame 10 and located at the compaction position 40. The compaction device 4 is used to compact the powder conveyed to the compaction position 40. By setting the compaction device 1 between the compaction device 4 and the cutting device 5, the continuity and consistency of the entire process from compaction to compaction and then to cutting is ensured. By setting the compaction device 1 to further compact the shaken or compacted material, material flow is reduced, and the surface smoothness of the material is improved. The effect of powder scattering is reduced, and the compacted powder structure is more compact and stable, ensuring a more uniform contact atmosphere in the kiln and promoting a more complete sintering reaction. The compacted material exhibits better uniformity and consistency during the sintering process, improving the quality and performance of the final product.

[0034] Please see Figure 3In some embodiments of this application, at least two compaction devices 1 are provided along the conveying direction of the conveying mechanism 3. By providing at least two compaction mechanisms 100, the powder to be compacted can be graded according to the pressure. Preferably, primary compaction mainly pre-compacts the material surface to avoid dust and overflow caused by excessive pressure in one compaction. Secondary compaction shapes the material to ensure a weak material flow. More preferably, tertiary compaction can also be provided to correct the material surface and correct any uncompacted areas to ensure that all material is compacted.

[0035] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and substance of the technical solutions of this application.
