Description

A cutting device Technical Field

[0001] This utility model belongs to the technical field of lithium battery cathode material production equipment, specifically relating to a cutting device. Background Technology

[0002] During the sintering process of cathode materials such as NCM, the dense internal structure of the material in the sagger leads to uneven heat and atmosphere transfer, easily resulting in localized over-sintering or under-sintering, which affects the material's crystal structure, processing performance, and electrochemical performance. Traditional dicing processes simply cut the powder material to be sintered in the sagger into blocks using molds, without optimizing the internal structure. This results in uneven heat distribution during sintering, requiring extended sintering time and producing products with poor consistency.

[0003] The existing cathode material molding dies are insufficient to solve the problem of a single heat conduction path within the powder material. Summary of the Invention

[0004] The purpose of this invention is to propose a cutting device to solve the problem of the single heat conduction path inside powder materials, which is difficult to solve in the prior art.

[0005] Therefore, this utility model provides a cutting device, including: a base plate; a plurality of cutting blades distributed on the surface of the base plate and arranged in a staggered manner in a preset shape; and a plurality of pins distributed among the plurality of cutting blades.

[0006] Preferably, the cutter divides the base plate into multiple matrix-distributed cutter blocks, and each cutter block is provided with a number of pins.

[0007] Preferably, each of the cutting blocks is provided with 5 pins, one of which is located at the center of the cutting block, and the remaining pins are distributed at the four corners of the cutting block.

[0008] Preferably, the pin is the same length as the cutter.

[0009] Preferably, the needle includes a needle body and a needle tip, with the needle tip located at the bottom of the needle body.

[0010] Preferably, the needle body is cylindrical.

[0011] Preferably, the diameter of the needle body is in the range of 0.5cm-1cm.

[0012] Preferably, the needle tip is a cone.

[0013] Preferably, the material of the insert is plastic.

[0014] Preferably, the surface of the pin is coated with a silicon carbide coating.

[0015] Beneficial effects:

[0016] This invention provides a cutting device that uses a cutting blade and a pin to press down simultaneously, cutting the powder material in the sagger into corresponding blocks. The pin forms a through channel between the blocks, allowing hot air to flow rapidly through the channel during sintering and quickly penetrate into the material, reducing the temperature difference of the material at different locations in the sagger and improving the uniformity of heat distribution during sintering.

Detailed Implementation

[0022] The following detailed description of preferred embodiments of the present invention, along with the included examples, will make the content of the present invention more readily understood. Unless otherwise specified, 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. In case of any conflict, the definitions in this specification shall prevail.

[0023] Example 1:

[0024] A cutting device as shown in Figures 1-2 is provided, including a base plate 101; a plurality of cutters 102 distributed on the surface of the base plate 101 and arranged in a staggered manner in a preset shape; and a plurality of pins 103 distributed among the plurality of cutters 102.

[0025] The cutter 102 divides the base plate 101 into multiple matrix-distributed cutter blocks 104, each cutter block 104 containing several pins 103. The number of cutter blocks 104 is n×n, where n is 2, 3, 4, 5, 6, 7... In this embodiment, the cutter 102 divides the base plate 101 into 6×6 cutter blocks 104, each cutter block 104 being the same size. Each cutter block 104 contains 5 pins 103, with one pin 103 located at the center of the cutter block 104 and the remaining pins 103 distributed at the four corners of the cutter block 104.

[0026] The insertion pin 103 is the same length as the cutter 102. While the cutter 102 cuts the powder material into corresponding blocks, the insertion pin 103 forms a through channel in the powder material, which facilitates the hot airflow to quickly penetrate into the material during subsequent sintering, reducing the temperature difference of the material at different locations.

[0027] The needle 103 includes a needle body and a needle tip, with the needle tip located at the bottom of the needle body. The needle body is cylindrical, with a diameter ranging from 0.5 cm to 1 cm. The needle tip is conical. The needle tip allows for easier insertion into powder materials.

[0028] The pin 103 is made of plastic. The surface of the pin 103 is coated with a silicon carbide coating.

[0029] The working principle is shown in Figure 3. The cutting device 100 is used in a slicing device, which includes a pneumatic device 200, a nylon pressure plate 300, a photoelectric sensor 400, and a sagger fixing push plate 500. The nylon pressure plate 300 is fixed to the bottom of the pneumatic device 200, and the cutting device 100 is fixed to the bottom of the nylon pressure plate 300. The pneumatic device 200 drives the nylon pressure plate 300 and the cutting device 100 to move up and down. The sagger fixing push plate 500 is located below the nylon pressure plate 300 and is used to fix the sagger. The photoelectric sensor 400 is used to detect the position of the cutting device 100.

[0030] The sagger containing the powder material is fixed using a sagger fixing pusher 500. A pneumatic device 200 drives a cutting device 100 downwards. The cutter 102 cuts the powder material in the sagger into several matrix-distributed blocks. Insert pins 103 are inserted into the powder material to form through channels. During subsequent sintering of the blocks, hot air can flow rapidly through these channels, quickly penetrating into the material and reducing temperature differences between different locations within the sagger, thus improving the uniformity of heat distribution during sintering.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
