The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0040] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0041] In the present application, battery cells may include lithium-ion secondary battery cells, lithium-ion primary battery cells, lithium-sulfur battery cells, sodium-lithium-ion battery cells, sodium-ion battery cells or magnesium-ion battery cells, etc., and the embodiments of the present application do not limit this. Battery cells may be cylindrical, flat, rectangular or other shapes, etc., and the embodiments of the present application do not limit this. Battery cells are generally divided into three types according to the packaging method: cylindrical battery cells, square battery cells and soft-pack battery cells, and the embodiments of the present application do not limit this.

[0042] In the preparation process of the pole piece of the battery cell, the powder and the solvent need to be mixed in the mixer first, and then a uniform slurry is formed after stirring and dispersing in the mixer. The slurry is pumped from the mixer to the transfer tank through the slurry pipeline, and then from the transfer tank to the coating machine head for the coating process. At present, a push ball is generally used to clean the residual slurry in the pipeline to prevent the pipeline from being blocked. However, the slurry is prone to agglomeration in the pipeline, resulting in the phenomenon of the push ball being stuck, which reduces the production efficiency of the battery cell.

[0043] In order to solve the above-mentioned technical problems, an embodiment of the present application provides a slurry pipe ball pushing structure, which includes a shell, a driving member and a rotating member, wherein the driving member is arranged inside the shell; the rotating member includes a rotating shaft and a rotating part, wherein the rotating shaft is located inside the shell, and the rotating part is located outside the shell, one end of the rotating shaft is connected to the driving member, and the other end is connected to the rotating part, the driving member is used to drive the rotating shaft to rotate, and a toothed part is arranged on the side of the rotating part facing away from the shell.

[0044] In the above scheme, the driving member drives the rotating shaft to rotate, which can drive the rotating part to rotate. When the entire ball-pushing structure moves forward, the teeth on the rotating part can break up the agglomerated slurry, so that the slurry pipeline is unblocked, thereby improving the production efficiency of the battery monomer.

[0045] Figure 1 is an exploded schematic diagram of a ball pushing structure of some embodiments of the present application; Figure 2 It is a structural schematic diagram of the ball pushing structure of some embodiments of the present application.

[0046] Please refer to Figure 1 and Figure 2 In the first aspect, the embodiment of the present application provides a slurry pipe ball pushing structure 500, which includes a shell 40, a driving member 50 and a rotating member 60. The driving member 50 is arranged inside the shell 40; the rotating member 60 includes a rotating shaft 61 and a rotating part 62. The rotating shaft 61 is located inside the shell 40, and the rotating part 62 is located outside the shell 40. One end of the rotating shaft 61 is connected to the driving member 50, and the other end is connected to the rotating part 62. The driving member 50 is used to drive the rotating shaft 61 to rotate, and a toothed part 621 is provided on the side of the rotating part 62 away from the shell 40.

[0047] The shape of the shell 40 can be the same as or similar to the shape of the slurry pipe. For example, if the shape of the pipe is cylindrical, the shape of the shell 40 is also cylindrical; or if the cross-sectional shape of the pipe is rectangular, the cross-sectional shape of the shell 40 is also rectangular. The shell 40 can be formed by a plurality of detachable sub-shells, or the shell 40 can be an integrally formed structure.

[0048] The driving member 50 may be a small motor, a cylinder or a hydraulic cylinder, etc. The rotating shaft 61 is connected to the output shaft 52 of the driving member 50, and may be connected by a key connection or a coupling. The rotating shaft 61 and the rotating part 62 may be fixedly connected by welding or bolts.

[0049] The outer contour of the rotating portion 62 may be cylindrical or elliptical, etc. The toothed portion 621 may include a plurality of teeth extending along the radial direction of the rotating portion 62, or the teeth of the toothed portion 621 may be triangular, trapezoidal or sawtooth-shaped, etc.

[0050] When the ball-pushing structure 500 is placed in the slurry pipeline, the rotating shaft 61 is located at the front end of the ball-pushing structure 500. By compressing the air in the pipeline at the rear end of the ball-pushing structure 500, the ball-pushing structure 500 is pushed to move forward.

[0051] In the above scheme, the driving member 50 drives the rotating shaft 61 to rotate, which can drive the rotating part 62 to rotate. When the entire ball-pushing structure 500 moves forward, the toothed portion 621 on the rotating part 62 can break up the agglomerated slurry, so that the slurry pipeline is unblocked, thereby improving the production efficiency of the battery cell.

[0052] In some embodiments, the housing 40 includes a first sub-shell 41 and a second sub-shell 42, and the first sub-shell 41 and the second sub-shell 42 are arranged along the axial direction of the rotating shaft 61; the hollow shaft 70 is sleeved on the outer periphery of the rotating shaft 61, and the first sub-shell 41 and the second sub-shell 42 are respectively detachably connected to the hollow shaft 70.

[0053] External threads can be provided on the outer periphery of both ends of the hollow shaft 70 along its axial direction, and internal threads can be provided inside the first sub-shell 41 and the second sub-shell 42 respectively, so that a detachable connection is achieved through the external threads of the hollow shaft 70 and the internal threads of the first sub-shell 41 and the second sub-shell 42 respectively.

[0054] Alternatively, the hollow shaft 70 may also be detachably connected to the first sub-shell 41 and the second sub-shell 42 respectively by means of snap-fitting, interference fit, etc.

[0055] The driving member 50 may be disposed in the first sub-shell 41 . One end of the rotating shaft 61 is inserted into the first sub-shell 41 and connected to the driving member 50 ; the other end of the rotating shaft 61 passes through the second sub-shell 42 and is connected to the rotating portion 62 .

[0056] It can be understood that when the driving member 50 drives the rotating shaft 61 to rotate, the hollow shaft 70 will not be affected and the hollow shaft 70 will not rotate.

[0057] In the above solution, the through-hole hollow shaft 70 is detachably connected to the first sub-shell 41 and the second sub-shell 42, which facilitates the disassembly of the outer shell 40. If any parts are damaged and need to be replaced, they can be disassembled and replaced separately, which reduces the cost.

[0058] In some embodiments, the slurry pipeline ball pushing structure 500 further includes a bearing 71 disposed between the rotating shaft 61 and the hollow shaft 70 , and the rotating shaft 61 and the hollow shaft 70 are connected via the bearing 71 .

[0059] One end of the rotating shaft 61 may be connected to the hollow shaft 70 via a bearing 71 , and the other end may be connected to the hollow shaft 70 via another bearing 71 .

[0060] In the above solution, the shaft 61 and the hollow shaft 70 are connected by the bearing 71, which can reduce friction, so that the driving member 50 drives the shaft 61 to rotate more smoothly, reducing energy loss.

[0061] In some embodiments, the slurry pipe ball pushing structure 500 further includes a scraper portion 80 , which is disposed on the outer periphery of the housing 40 .

[0062] The edge of the scraper portion 80 may be in the shape of a sharp blade and may be disposed around the outer circumference of the housing 40 .

[0063] In the above solution, when the ball-pushing structure 500 moves forward, the scraping portion 80 can scrape off the slurry remaining in the pipeline to clean the pipeline, thereby improving the efficiency of the ball-pushing structure 500 in cleaning the slurry pipeline.

[0064] In some embodiments, there are multiple scraping portions 80 , and the multiple scraping portions 80 are arranged at intervals along the axial direction of the rotating shaft 61 .

[0065] Exemplarily, the housing 40 includes a first sub-shell 41, a third sub-shell 43, and a second sub-shell 42 arranged in sequence along the axial direction of the rotating shaft 61, and the first sub-shell 41 and the second sub-shell 42 are respectively detachably connected to the hollow shaft 70. The third sub-shell 43 is located between the first sub-shell 41 and the second sub-shell 42, and the first sub-shell 41 and the third sub-shell 43 clamp one scraper portion 80, and the third sub-shell 43 and the second sub-shell 42 clamp another scraper portion 80.

[0066] In the above solution, by arranging a plurality of spaced scraping portions 80 along the axial direction of the rotating shaft 61 , the efficiency of the ball pushing structure 500 in cleaning the slurry pipeline can be further improved.

[0067] In some embodiments, the scraper portion 80 is detachably connected to the housing 40 .

[0068] The scraper portion 80 can be detachably connected to the housing 40 by means of snap connection, bolts, etc.

[0069] In the above solution, by detachably connecting the scraper portion 80 to the housing 40, the maintenance cost can be reduced.

[0070] Figure 3 It is a schematic diagram of the structure of the driving component of some embodiments of the present application.

[0071] like Figure 3 As shown, in some embodiments, the driving member 50 includes a driving body 51 and an output shaft 52 . The output shaft 52 is disposed on the driving body 51 , and the output shaft 52 is connected to the rotating shaft 61 via a key.

[0072] The driving body 51 is the core part of the entire driving part 50, which is mainly composed of a stator and a rotor. The stator is the stationary part of the driving part 50, and usually includes a stator core, a stator winding and a frame. The stator core is made of stacked silicon steel sheets, and its function is to provide a magnetic field path. The stator winding is wound by insulated wires. When three-phase alternating current is passed (if it is a three-phase motor), a rotating magnetic field will be generated inside the stator core. The rotor is the rotating part of the driving part 50, and has different structures depending on the type of driving part 50. For example, in an induction motor, the rotor is mainly composed of a rotor core, a rotor winding and a rotating shaft 61. The rotor core is also made of stacked silicon steel sheets. The rotor winding generates an induced electromotive force and an induced current under the action of the rotating magnetic field, and then is subjected to force in the magnetic field to cause the rotor to rotate.

[0073] The output shaft 52 is a part of the driving body 51, which extends from the driving body 51 and is a component for outputting mechanical energy of the motor. One end of the output shaft 52 is fixedly connected to the rotor inside the driving body 51 to ensure that the rotational motion of the rotor can be transmitted.

[0074] Key connection is a mechanical connection method, in which a key is used to transmit torque between the output shaft 52 and the rotating shaft 61. Keyways 611 are machined at the connection parts of the output shaft 52 and the rotating shaft 61. The key can be a small rectangular or semicircular part, which is installed in the keyway 611 of the output shaft 52, and partly exposed outside the keyway 611. When the rotating shaft 61 is assembled with the output shaft 52, the keyway 611 of the rotating shaft 61 is aligned with the key on the output shaft 52, so that the key is embedded in the keyway 611 of the rotating shaft 61.

[0075] In the above solution, the torque can be effectively transmitted through the key connection, meeting the requirement of high torque transmission, so that the ball pushing structure 500 can operate more stably.

[0076] Figure 3 is a schematic diagram of the structure of a driving member in some embodiments of the present application; Figure 4 It is a schematic diagram of the structure of the rotating parts of some embodiments of the present application.

[0077] Please refer to Figure 3 and Figure 4 In some embodiments, a groove 521 is formed on one side of the output shaft 52 facing the driving body 51, and the groove 521 includes a bottom wall 522 and a side wall 523 arranged around the bottom wall 522, and a guide key 524 is arranged on the side wall 523; a keyway 611 is arranged on the outer periphery of the rotating shaft 61, and the end of the rotating shaft 61 is inserted into the groove 521, and the guide key 524 is located in the keyway 611.

[0078] The bottom wall 522 of the groove 521 on the output shaft 52 is a planar structure, which together with the side wall 523 encloses a space for accommodating the end of the rotating shaft 61. The groove 521 as a whole provides a positioning and accommodating space for the end of the rotating shaft 61, so that the rotating shaft 61 can have a relatively accurate and stable initial installation position when connected to the output shaft 52.

[0079] The guide key 524 can be a long block structure, and its cross-sectional shape can be rectangular or trapezoidal, and is installed on the side wall 523 of the groove 521. The length of the guide key 524 can be adapted to the height of the side wall 523, so that after installation, it has enough length to cooperate with the key groove 611 on the rotating shaft 61. When installing the rotating shaft 61 and the output shaft 52, the guide key 524 plays a guiding role. Because it protrudes from the side wall 523 of the groove 521 and is located at a specific position, when the end of the rotating shaft 61 is close to the groove 521 of the output shaft 52, the guide key 524 can first contact with the key groove 611 on the periphery of the rotating shaft 61, so that the rotating shaft 61 can only be inserted into the groove 521 along the direction defined by the guide key 524. During the movement of the ball-pushing structure 500, the guide key 524 is located in the key groove 611 of the rotating shaft 61 and fits tightly with the side of the key groove 611. When the motor output shaft 52 rotates and transmits torque, the guide key 524 not only transmits torque like an ordinary key, but also limits the rotating shaft 61 from the side to prevent the rotating shaft 61 from relative displacement or loosening in the circumferential direction and axial direction.

[0080] In the above scheme, the groove 521 cooperates with the guide key 524 to provide directional guidance for the installation of the rotating shaft 61 and the output shaft 52, thereby improving the installation efficiency and increasing the stability of the connection between the output shaft 52 and the rotating shaft 61.

[0081] Figure 5 It is a structural schematic diagram of the ball pushing structure of other embodiments of the present application.

[0082] like Figure 5As shown, in some embodiments, the slurry pipeline ball pushing structure 500 also includes a power module 91 and a circuit board 92 built into the housing 40 , and the power module 91 and the circuit board 92 are respectively connected to the driving member 50 .

[0083] The power module 91 may adopt a battery pack structure composed of multiple rechargeable batteries.

[0084] In order to convert the control signal from the microcontroller into a suitable electrical signal that can drive the driver 50 to work, a power drive circuit is provided on the circuit board 92. It plays the role of power amplification. According to the type of the driver 50 (such as a DC motor, an AC motor, etc.) and the power requirement, the weak electric signal output by the microcontroller is amplified into a strong electric signal sufficient to drive the driver 50 to operate normally, so that the driver 50 can obtain sufficient electric energy to generate the required torque and speed, thereby effectively driving the rotating part 62 to work.

[0085] In the above scheme, the power module 91 can provide an independent power source for the ball pushing structure 500, and the circuit board 92 can effectively control the working state of the driving member 50, further improving the efficiency of the ball pushing structure 500 in cleaning the slurry pipeline.

[0086] In some embodiments, the side of the rotating portion 62 facing away from the housing 40 is a cone.

[0087] The rotating part 62 is designed as a cone on the side away from the housing 40, and its shape gradually decreases from the connection part with the rotating shaft 61, similar to a part of a cone. The cone has a tip and a side surface that gradually expands toward the rear.

[0088] When the rotating part 62 rotates, the tip of the cone first contacts the agglomerated slurry. Due to its sharp shape, the force generated during the rotation process can be concentrated on a smaller area, just like a sharp nail is easier to drive into an object. The tip of the cone can generate a greater pressure at the moment of contact with the agglomerated slurry, making it easier to destroy and crush the agglomerate locally. This effect of concentrated stress is particularly effective for agglomerated slurries with a harder texture and a larger volume, and can quickly form a rupture point on the surface of the agglomerate.

[0089] In the above solution, by setting the front end of the rotating part 62 as a cone, the rotating part 62 can more easily break up the agglomerated slurry, thereby further improving the production efficiency of the battery monomer.

[0090] In some embodiments, a corrosion-resistant layer 622 is disposed on the surface of the toothed portion 621 .

[0091] The material of the corrosion-resistant layer 622 may include corrosion-resistant paint, ceramic coating, metal alloy plating, etc. For example, epoxy resin-based anti-corrosion paint has the characteristics of strong adhesion and good chemical corrosion resistance, and can form a continuous and dense protective film on the surface of the tooth-shaped portion 621; ceramic coatings such as alumina ceramic coatings have high hardness and strong chemical inertness, and have excellent performance in resisting corrosive components such as acids and alkalis; metal alloy plating, such as chrome plating, nickel plating, etc., can not only improve the corrosion resistance of the tooth-shaped portion 621, but also increase the hardness and wear resistance of the surface to a certain extent.

[0092] In the above solution, the corrosion-resistant layer 622 can play a barrier role, preventing the corrosive components in the slurry from directly contacting the base material of the tooth-shaped portion 621 to a certain extent, thereby protecting the tooth-shaped portion 621 from corrosion.

[0093] In a second aspect, an embodiment of the present application further provides a battery production system, comprising a slurry pipeline ball pushing structure 500 of any of the above-mentioned embodiments.

[0094] According to some embodiments of the present application, the present application provides a slurry pipeline ball-pushing structure 500, which includes a housing 40, a driving member 50 and a rotating member 60, wherein the driving member 50 is arranged inside the housing 40; the rotating member 60 includes a rotating shaft 61 and a rotating portion 62, wherein the rotating shaft 61 is located inside the housing 40, and the rotating portion 62 is located outside the housing 40, wherein one end of the rotating shaft 61 is connected to the driving member 50, and the other end is connected to the rotating portion 62, wherein the driving member 50 is used to drive the rotating shaft 61 to rotate, and a toothed portion 621 is arranged on the side of the rotating portion 62 away from the housing 40. The housing 40 includes a first sub-shell 41 and a second sub-shell 42, wherein the first sub-shell 41 and the second sub-shell 42 are arranged along the axial direction of the rotating shaft 61; and a hollow shaft 70 is sleeved on the outer periphery of the rotating shaft 61, wherein the first sub-shell 41 and the second sub-shell 42 are detachably connected to the hollow shaft 70 respectively.
