Abstract
Description
Technical Field
[0001] This utility model relates to the field of production equipment technology, and more specifically, to a shredding vibration device and a lithium battery cathode material production system. Background Technology
[0002] In the production of 5-series products (such as NCM523 or NCM532) in the ternary lithium-ion battery cathode material manufacturing industry, existing recycling lines often transport materials directly to the unloading station after the shredding station. Based on the operating conditions of 5-series products, this equipment can meet the production requirements.
[0003] However, when producing 6-series products (such as NCM622), due to changes in material properties (increased viscosity), after passing through the shredder of 5-series products and undergoing another vibration before entering the unloading station, not all the material in the sagger can be transferred by tilting; the unloading completion rate is only about 50%. In this situation, manual assistance is required to assist with unloading, increasing labor costs.
[0004] Therefore, there is an urgent need to develop equipment that can automatically tilt the 6-series products to reduce the manpower consumption in the production process of the 6-series products.
[0005] Therefore, this application is submitted. Utility Model Content
[0006] The purpose of this utility model is to provide a shredding vibration device and a lithium battery cathode material production system, which can fluff the material and realize the function of automatic tilting of 6-series products.
[0007] The embodiments of this utility model can be implemented as follows:
[0008] In a first aspect, this utility model provides a chopping vibration device, including a material container and a conveyor line for conveying the material container. A first vibration mechanism, a chopping mechanism and a second vibration mechanism are sequentially arranged along the conveying direction of the conveyor line. The material container passes through the first vibration mechanism, the chopping mechanism and the second vibration mechanism in sequence under the conveying of the conveyor line.
[0009] The shredding mechanism includes a mounting plate and a drive motor for driving the mounting plate to move up and down. The mounting plate is provided with a first cutting plate, a second cutting plate and an edge cutting plate. The edge cutting plate is arranged around the first cutting plate and the second cutting plate, and the first cutting plate and the second cutting plate are in an intersecting state.

[0012] In an optional embodiment, at least one of the first vibration mechanism and the second vibration mechanism includes:
[0013] Vibration mounting base, with a material container placed on top of the vibration mounting base;
[0014] The oscillator is mounted below the vibration mounting base;
[0015] The cylinder mounting cover is located below the vibration mount and is connected to the vibration mount via a buffer assembly.
[0016] The cylinder is installed below the cylinder mounting cover and is used to drive the cylinder mounting cover and the vibrating mounting base to rise and fall, thereby driving the material container to rise and fall.

[0036] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0037] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0038] Please refer to Figure 1 and Figure 2 This utility model provides a chopping vibration device, including a material container 001 and a conveyor line 002 for conveying the material container 001. A first vibration mechanism 110, a chopping mechanism 120 and a second vibration mechanism 130 are arranged sequentially along the conveying direction of the conveyor line 002. The material container 001 passes through three stations of the first vibration mechanism 110, the chopping mechanism 120 and the second vibration mechanism 130 in sequence under the conveying of the conveyor line 002, and undergoes three processes of vibration-chopping-vibration.
[0039] Specifically, the material container 001 can be a common crucible used to hold lithium battery cathode materials. The conveying method of the conveyor line 002 is not limited; it can be an existing conveying device such as a ceramic rod conveyor line. Position sensors are installed at each of the three stations: the first vibration mechanism 110, the chopping mechanism 120, and the second vibration mechanism 130. These sensors detect whether the crucible has been transported to the corresponding workstation via photoelectric sensors, and then perform the corresponding workstation operation. For example, when the material container 001 is detected to have been transported to the first vibration mechanism 110, the conveying stops, and the first vibration mechanism 110 vibrates the material inside the material container 001; when the material container 001 is detected to have been transported to a position below the chopping mechanism 120, the conveying stops, and the chopping mechanism 120 performs the chopping; when the material container 001 is detected to have been transported to the second vibration mechanism 130, the conveying stops, and the second vibration mechanism 130 vibrates the material inside the material container 001.
[0040] Figure 2 , Figure 3 and Figure 4 The diagram shows the structure of the first vibration mechanism 110. The specific structure of the second vibration mechanism 130 can be the same as that of the first vibration mechanism 110. The specific structure will not be described again.
[0041] In some embodiments, the first vibration mechanism 110 includes a vibration mounting base 111, an oscillator 112, a cylinder mounting cover 113, and a cylinder 115. The vibration mounting base 111 is used to place a material container 001 on top of it, and is approximately the same shape and size as the material container 001. The oscillator 112 is mounted below the vibration mounting base 111 and vibrates during operation to loosen the material in the material container 001. The cylinder mounting cover 113 is located below the vibration mounting base 111 and is connected to the vibration mounting base 111 through a buffer assembly 114, which provides a buffering effect. The cylinder 115 is mounted below the cylinder mounting cover 113 and is used to drive the cylinder mounting cover 113 and the vibration mounting base 111 to rise and fall, thereby driving the material container 001 to rise and fall.
[0042] Specifically, cylinder 115 can be a general three-axis cylinder, oscillator 112 can be a common turbine oscillator, and cylinder mounting cover 113, model GT-06, can also be called a lifting cylinder bellows cover, which protects the spring and fixing parts and prevents contamination by metal foreign objects; cylinder mounting cover 113 is also used for supporting devices above cylinder 115.
[0043] In some embodiments, the buffer assembly 114 includes a top fixing member 1141, an elastic member 1142, and a bottom fixing member 1143. The elastic member 1142 is located between the top fixing member 1141 and the bottom fixing member 1143. The top fixing member 1141 is connected to the lower part of the vibration mounting base 111, and the bottom fixing member 1143 is connected to the upper part of the cylinder mounting cover 113. The elastic member 1142 can be a rectangular spring, installed in the top fixing member 1141 and the bottom fixing member 1143. The elastic member 1142 is driven in conjunction with the oscillator 112, using the elastic force of the spring to transmit vibration energy, causing the material to vibrate regularly.
[0044] Specifically, when the material container 001 (such as a sagger) is detected to be in position, the drive motor stops working, the cylinder 115 rises and lifts, and the cylinder 115 is also equipped with a lifting position detection structure. When the lifting position is detected, the vibrator 112 starts to vibrate, and the elastic element 1142 cooperates with the vibrator 112 to drive it. The elastic force of the spring is used to transmit vibration energy, so that the material produces regular vibration. The vibration time can be set. When the vibration time set by the program is reached, the vibrator 112 stops working, the cylinder 115 descends, and the sagger is removed.
[0045] Furthermore, multiple buffer components 114 are spaced apart, for example, four, installed at the four corners to provide a more stable support. Shock-absorbing rubber 118 can also be installed below the cylinder mounting cover 113 to absorb vibrations, buffer them, and suppress noise through elastic deformation.
[0046] In some embodiments, the edge of the vibration mounting base 111 is provided with a blocking block 1111 to limit the material container 001 and restrict the amplitude of the sagger within a certain range. In a preferred embodiment, the material container 001 has a quadrilateral cross-sectional shape, and blocking blocks 1111 are provided at the four corners of the top of the vibration mounting base 111 to limit the four corners of the material container 001 and achieve a better limiting effect.
[0047] In some embodiments, the first vibration mechanism 110 further includes a cylinder mounting bracket 116 and a supporting horizontal tube frame 117. The cylinder 115 is mounted on the cylinder mounting bracket 116, and the cylinder mounting bracket 116 is mounted on the supporting horizontal tube frame 117. The supporting horizontal tube frame 117 can be installed on the ground, and the cylinder mounting bracket 116 is fixed above the supporting horizontal tube frame 117, providing stable support for the upper structure.
[0048] Other structures in the first vibration mechanism 110, such as bolts and washers, can be referred to in the attached drawings to ensure that each part can be stably fixed and installed. The specific structure will not be described in detail.
[0049] like Figure 5 and Figure 6 As shown, the shredding mechanism 120 includes a mounting plate 121 and a drive motor (not shown) for driving the mounting plate 121 to move up and down. The mounting plate 121 is equipped with a first cutting plate 122, a second cutting plate 123, and an edge cutting plate 124. The edge cutting plate 124 surrounds the first cutting plate 122 and the second cutting plate 123, meaning the first cutting plate 122 and the second cutting plate 123 are located in the middle of the area enclosed by the edge cutting plate 124. The first cutting plate 122 and the second cutting plate 123 are intersecting, dividing the area into four regions, resulting in four large pieces after shredding.
[0050] In some embodiments, the first cutting plate 122 and the second cutting plate 123 are in a cross-shaped state, which facilitates manufacturing and can divide the inner cavity surrounded by the edge cutting plate 124 into four chambers.
[0051] Furthermore, the edge cutting plate 124 includes four separate corner cutting plates 125. Each corner cutting plate 125, together with the first cutting plate 122 and the second cutting plate 123, forms an independent and non-closed chamber. The edges of the corner cutting plates 125 are spaced apart from the first cutting plate 122 and the second cutting plate 123, with a certain gap, so as to discharge excess gas in the material by utilizing the gap between the cutters.
[0052] This utility model embodiment also provides a lithium battery cathode material production system, including the above-mentioned shredding and vibration device, and may also include sintering furnace, reaction vessel and other structures to form a complete lithium battery cathode material production system.
[0053] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
