Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to an automatic battery slurry feeding mechanism. Background Technology

[0002] The automatic battery slurry feeding mechanism is a core piece of equipment in battery production. Its function is to accurately and stably deliver electrode slurry (such as positive and negative electrode materials, binders, and dispersants) to the coating process, which directly affects the quality and consistency of battery electrodes.

[0003] In the existing technology, the equipment mixes powder and liquid materials according to a preset ratio using a loss-in-weight weighing scale and a screw pump. A high-solids-content screw mixer conveyor first premixes the dry powder, then gradually injects the liquid material to form a high-viscosity slurry. Finally, a three-paddle mixer in a different location completes the fine dispersion. A diaphragm pump and a screw pump transport the slurry to the coating machine's feed tank. The feed rate is adjusted in real time using a liquid level sensor. However, the mixer design of some mechanisms is unreasonable, which fails to improve the uniformity of the slurry, resulting in stratification and solidification of the slurry in the mixing tank. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an automatic battery slurry feeding mechanism, which aims to improve the problem that the mixer design of some mechanisms in the prior art is unreasonable, which fails to improve the uniformity of the slurry and causes the slurry to separate and solidify in the mixing tank.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic battery slurry feeding mechanism, comprising a support frame, a mixing tank installed on the inner side of the support frame, a support plate fixedly connected to the top of the support frame, a mixing mechanism installed on the front side of the top wall of the support plate, the mixing mechanism being used to mix the battery slurry, and an installation mechanism installed on the outer wall of the support plate, the installation mechanism being used to facilitate the installation and disassembly of components; the mixing mechanism includes a motor, the motor being fixedly connected to the front side of the top wall of the support plate, an internal gear ring being fixedly connected to the top of the mixing tank, and a connecting shaft being fixedly connected to the output end of the motor.

[0006] As a further description of the above technical solution:

[0007] A crank two is fixedly connected to the bottom of the connecting shaft, and a stirring blade two is fixedly connected to the bottom end of the crank two. A transmission assembly is installed on the inner wall of the crank two.

[0008] As a further description of the above technical solution:

[0009] The transmission assembly includes a gear, which is rotatably connected to the inner wall of crank two. The gear meshes with an internal gear ring. Crank one is fixedly connected to the bottom end of the gear, and stirring blade one is fixedly connected to the end of crank one.

[0010] As a further description of the above technical solution:

[0011] The installation mechanism includes a mounting base, which is fixedly connected to the front side of the outer wall of the support plate, and a mounting block is slidably connected to the inner wall of the mounting base.

[0012] As a further description of the above technical solution:

[0013] A liquid level sensor is fixedly connected to the front side of the outer wall of the mounting block, and a housing is fixedly connected to the right side of the outer wall of the mounting base. A drive assembly is installed on the inner wall of the housing.

[0014] As a further description of the above technical solution:

[0015] The drive assembly includes a knob that is rotatably connected to the inner wall of the housing. A protrusion is threaded onto the outer wall of the knob. A slider is slidably connected to the left side of the inner wall of the housing. The protrusion is slidably connected to the inner wall of the slider. A locking block is fixedly connected to the end of the slider. The locking block is slidably connected to the inner wall of the mounting base and to the outer wall of the mounting block.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, after the motor starts, the transmission connecting shaft drives the crank two and the stirring blade two on its bottom wall to rotate synchronously. The rotation of the crank two drives the gear to rotate. The gear rotates along the inner gear ring on the inner wall of the crank two. The rotation of the gear drives the crank one and the stirring blade one to rotate. Through the rotation of the stirring blade two and the rotation of the stirring blade one around it, the battery slurry in the mixing tank is stirred in all directions and at multiple angles, which improves the uniformity of the slurry and prevents the slurry in the mixing tank from stratifying and solidifying.

[0022] 2. In this utility model, when installing the liquid level sensor, the mounting block on the back side of the liquid level sensor is slid upward along the inner wall of the mounting base, and then the knob is rotated. The rotation of the knob drives the protrusion on its outer wall to slide backward inside the housing. The protrusion moves to compress the slider and pushes the slider to move the locking block outward, so that the locking block is inserted into the mounting base. At the same time, the locking block will lock the upper and lower ends of the mounting block to prevent the mounting block from slipping out of the mounting base, forming a stable connection, which facilitates the installation and removal of the liquid level sensor and improves maintenance efficiency.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an automatic battery slurry feeding mechanism, comprising a support frame 1, a mixing tank 5 mounted on the inner side of the support frame 1, a support plate 2 fixedly connected to the top of the support frame 1, a mixing mechanism 3 mounted on the front side of the top wall of the support plate 2, the mixing mechanism 3 being used to mix the battery slurry, and an installation mechanism 4 mounted on the outer wall of the support plate 2 for convenient installation and disassembly of components; the mixing mechanism 3 includes a motor 306, which is a Dongfang Motor PK series, with a compact design, the motor 306 being fixedly connected to the front side of the top wall of the support plate 2, and the top of the mixing tank 5 being fixed... An internal gear ring 301 is connected to the motor 306. The output end of the motor 306 is fixedly connected to a connecting shaft 305. The bottom of the connecting shaft 305 is fixedly connected to a crank 304. The bottom end of the crank 304 is fixedly connected to a stirring blade 303. A transmission assembly 302 is installed on the inner wall of the crank 304. The transmission assembly 302 includes a gear 3021. The gear 3021 is rotatably connected to the inner wall of the crank 304. The gear 3021 meshes with the internal gear ring 301. The bottom end of the gear 3021 is fixedly connected to a crank 3022. The end of the crank 3022 is fixedly connected to a stirring blade 3023.

[0032] Specifically, after the motor 306 starts, it transmits power to the connecting shaft 305. The connecting shaft 305 drives the crank 304 connected to it and the stirring blade 303 mounted on its bottom wall to rotate synchronously. During the rotation of the crank 304, it further drives the gear 3021 connected to it to start rotating. The gear 3021 rotates along the internal gear ring 301. The rotation of the gear 3021 drives the crank 3022 and the stirring blade 3023 connected to it to rotate. While the stirring blade 303 rotates on its own axis, the stirring blade 3023 rotates around the central axis of the mixing tank 5. The two work together to achieve the stirring of the contents of the mixing tank 5. The comprehensive and multi-angle stirring effect of the battery slurry is crucial. Specifically, the main materials for the positive electrode should be nickel hydroxide and manganese dioxide, which play a key role in battery performance. The main materials for the negative electrode should be hydrogen storage alloy, zinc oxide, and iron oxide. These materials can effectively improve the battery's energy storage capacity and stability. Water is used as the dispersant. The addition of water can not only effectively disperse the various components in the slurry, but also ensure that the battery slurry in the stirring tank 5 reaches an ideal uniform state through this stirring method. It can prevent stratification and slurry solidification during the stirring process, and ensure that the slurry always maintains good fluidity and uniformity.

[0033] Reference Figure 1 , Figure 2 and Figure 5The mounting mechanism 4 includes a mounting base 405, which is fixedly connected to the front side of the outer wall of the support plate 2. A mounting block 404 is slidably connected to the inner wall of the mounting base 405. A liquid level sensor 403, which is a Siemens SITRANSLR250, is fixedly connected to the front side of the outer wall of the mounting block 404. A housing 401 is fixedly connected to the right side of the outer wall of the mounting base 405. A drive assembly 402 is installed on the inner wall of the housing 401. Includes a knob 4022, which is rotatably connected to the inner wall of the housing 401. A protrusion 4021 is threadedly connected to the outer wall of the knob 4022. A slider 4023 is slidably connected to the left side of the inner wall of the housing 401. The protrusion 4021 is slidably connected to the inner wall of the slider 4023. A locking block 4024 is fixedly connected to the end of the slider 4023. The locking block 4024 is slidably connected to the inner wall of the mounting base 405 and the outer wall of the mounting block 404.

[0034] Specifically, the function of the liquid level sensor 403 is to accurately collect the real-time liquid level of the battery slurry in the tank and transmit the liquid level signal to the controller 8. When installing the liquid level sensor 403, slide the mounting block 404 on the back of the liquid level sensor 403 upward along the inner wall of the mounting base 405, and then rotate the knob 4022. The rotation of the knob 4022 drives the protrusion 4021 on its outer wall to slide backward inside the outer shell 401. The protrusion 4021 moves to compress the slider 4023 and pushes the slider 4023 to drive the locking block 4024 to move outward, so that the locking block 4024 is inserted into the mounting base 405. At the same time, the locking block 4024 will lock the upper and lower ends of the mounting block 404 to prevent the mounting block 404 from slipping out of the mounting base 405, forming a stable connection, which facilitates the installation and removal of the liquid level sensor 403 and improves maintenance efficiency.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A controller 8 is installed on the outer wall of the support frame 1. The controller 8 is a PLC programmable logic controller 8, Siemens S7-1200 series. The controller 8 is fixedly connected to the left side of the outer wall of the support frame 1. The bottom wall of the mixing tank 5 is connected to the conveying pipe 6. A valve 7 is installed on the outer wall of the conveying pipe 6.

[0036] Specifically, the controller 8 receives feedback signals from the liquid level sensor 403 in real time (such as whether the slurry level is below the lower limit or whether the viscosity exceeds the process range), and outputs control signals to adjust the operation of each component according to the preset program or operator instructions. The conveying pipe 6 needs to stably transport the uniformly stirred battery slurry to the next process, and the valve 7 is used to control the flow rate of the conveying pipe 6.

[0037] Working principle: After the motor 306 starts, it drives the connecting shaft 305. The connecting shaft 305 drives the crank 2 304 and the stirring blade 2 303 on its bottom wall to rotate synchronously. The rotation of the crank 2 304 drives the gear 3021 to rotate. The gear 3021 rotates along the inner gear ring 301 on the inner wall of the crank 2 304. The rotation of the gear 3021 drives the crank 1 3022 and the stirring blade 1 3023 to rotate. Through the rotation of the stirring blade 2 303 and the rotation of the stirring blade 1 3023 around it, the battery slurry in the mixing tank 5 is stirred in all directions and at multiple angles, which improves the uniformity of the slurry and prevents the slurry in the mixing tank 5 from stratifying and solidifying.

[0038] When installing the liquid level sensor 403, slide the mounting block 404 on the rear side of the liquid level sensor 403 upward along the inner wall of the mounting base 405, and then rotate the knob 4022. The rotation of the knob 4022 drives the protrusion 4021 on its outer wall to slide backward inside the housing 401. The protrusion 4021 moves to compress the slider 4023 and pushes the slider 4023 to drive the locking block 4024 to move outward, so that the locking block 4024 is inserted into the mounting base 405. At the same time, the locking block 4024 will lock the upper and lower ends of the mounting block 404 to prevent the mounting block 404 from slipping out of the mounting base 405, forming a stable connection, which facilitates the installation and removal of the liquid level sensor 403 and improves maintenance efficiency.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
