[0049] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present application and should not be construed as limiting the present application.

[0050] The present application aims to at least solve the technical problem of too large blade spacing in the related art. For this purpose, the present application provides a tool rest, a pole piece cutting device and a battery cell processing system, which can adjust the distance between two blades to meet the process requirements for cutting the middle tab.

[0051] Next, reference is made to Figures 1-5 Describe the tool rest 1 according to the embodiment of the present application.

[0052] As Figure 1 and Figure 2 shown, the tool rest 1 includes: a blade adjustment assembly 10, a mounting member 40 and a drive mechanism 20.

[0053] The blade adjustment assembly 10 is the core control part of the tool rest 1, responsible for adjusting the position and angle of the blade to ensure that the blade can cut the pole piece accurately and stably. The blade adjustment assembly 10 usually includes components such as the blade-leaning adjustment assembly 110, the blade-penetration adjustment assembly 120, and the angle adjustment assembly 130. By manually or automatically adjusting these components, precise control of the blade can be achieved.

[0054] The output end of the blade adjustment assembly 10 is directly connected to the mounting part 40. As an intermediary, the mounting part 40 can transmit the adjustment action of the adjustment assembly to the blade, playing a bridging role. At the same time, it connects the blade adjustment assembly 10 with the drive mechanism 20 and the blade, ensuring the stability and reliability of the entire tool rest 1 system. The mounting part 40 is usually made of high-strength and high-precision materials, such as aluminum alloy or stainless steel, to withstand the forces and vibrations generated during the cutting process.

[0055] The drive mechanism 20 is the power source of the tool rest 1, responsible for providing the power required for cutting the blade. It can adjust parameters such as rotational speed and torque according to needs to adapt to different cutting requirements. The drive mechanism 20 is installed on the mounting part 40 and is connected to the blade mounting part 40 through a transmission mechanism 220, such as gears, belts, etc., to transmit the power to the blade.

[0056] The first blade mounting part 411 and the second blade mounting part 412 are the direct supporting parts of the blade, respectively provided with a first blade mounting position and a second blade mounting position for installing and fixing the blade. By arranging them side by side, simultaneous or alternating cutting can be achieved, improving the cutting efficiency. Both the first blade mounting part 411 and the second blade mounting part 412 are power-coupled to the drive mechanism 20 and can simultaneously receive the power from the drive mechanism 20 and perform cutting actions synchronously or asynchronously.

[0057] During the pole piece splitting process, first, the blade adjustment assembly 10 adjusts parameters such as the position and angle of the blade, then the drive mechanism 20 is started, and the power is transmitted from the drive mechanism 20 to the blades installed on the first blade mounting part 411 and the second blade mounting part 412. Finally, the blade cuts the pole piece under the drive of the power.

[0058] It can be understood that the tool rest 1 can ensure the accuracy and efficiency of the cutting process through precise adjustment and stable power transmission.

[0059] In the related art, usually two electronic upper cutting tool holders 1 are placed side by side back to back. There are components arranged horizontally between the upper tool holders 1, and the distance between the blades is too large to meet the process requirements for cutting the middle tab. In the present application, two cutting blades can be installed on one tool holder 1 at the same time, achieving the effect of reducing the distance between the two cutting blades to meet the process requirements for cutting the middle tab, making its application range wider, and at the same time making the adjustment of the cutting tool simple and fast, and the movement of the cutting tool stable.

[0060] According to the tool holder 1 provided by the embodiment of the present application, through the cooperation of the blade adjustment assembly 10, the mounting member 40 and the driving mechanism 20, the first blade 421 and the second blade 422 can be installed on the tool holder 1 at the same time, and the distance between the two blades can be adjusted to meet the process requirements for cutting the middle tab. At the same time, the adjustment process of the blade can be simplified through the blade adjustment assembly 10, and the movement of the blade can be made more stable.

[0061] In some embodiments, such as Figure 3 and Figure 4 shown, the first blade mounting member 411 includes: a first cutter disk 431 and a first cutter disk fixing cover 441, and the second blade mounting member 412 includes: a second cutter disk 432 and a second cutter disk fixing cover 442.

[0062] Among them, the first cutter disk 431 is power-coupled to the driving mechanism 20 in a certain way, such as a keyway, a spline, etc., so as to receive the power from the driving mechanism 20 to rotate or perform other forms of movement. The first cutter disk 431 has a first blade mounting position for mounting the first blade 421. The first blade mounting position can be a slot, a card slot or other forms of fixing structures to ensure that the first blade 421 can be firmly mounted on the first cutter disk 431. The first cutter disk fixing cover 441 is disposed opposite to the first cutter disk 431 and is used to clamp the first blade 421 together with the first cutter disk 431 to ensure that the first blade 421 will not loosen or fall off during the working process. The fixing cover can usually be connected to the cutter disk by screws, buckles or other fasteners. The first blade mounting position is located between the first cutter disk 431 and the first cutter disk fixing cover 441.

[0063] The second cutter head 432 is power-coupled to the first cutter head 431 by bolts, so as to move synchronously with the first cutter head 431. Similar to the first cutter head 431, the second cutter head 432 has a second blade mounting position for mounting the second blade 422. The second blade mounting position can be a slot, a clamping groove or other forms of fixing structures to ensure that the second blade 422 can be firmly mounted on the second cutter head 432. The second cutter head fixing cover 442 is disposed opposite to the second cutter head 432 and is used to jointly clamp the second blade 422 with the second cutter head 432 to ensure that the second blade 422 will not loosen or fall off during the working process. The fixing cover can usually be connected to the cutter head by screws, buckles or other fasteners. The second blade mounting position is located between the second cutter head 432 and the second cutter head fixing cover 442.

[0064] It can be understood that the second cutter head 432 is connected to the first cutter head 431, multiple blades can be installed on a single device, and the blades installed on the two cutter heads can work synchronously.

[0065] In some embodiments, as Figure 3 shown, the first cutter head fixing cover 441 is detachably connected to the first cutter head 431, and the second cutter head fixing cover 442 is detachably connected to the second cutter head 432.

[0066] The first cutter head fixing cover 441 is detachably connected to the first cutter head 431, and the second cutter head fixing cover 442 is detachably connected to the second cutter head 432. For example, bolts or buckle connections can be used to fasten the fixing cover to the cutter head. When the blade is worn or needs to be replaced, the detachable connection can easily remove the fixing cover to access and replace the blade, thereby reducing the downtime and improving the maintenance efficiency of the equipment. At the same time, different processing tasks may require different types of blades. Through the detachable connection, different types of blades can be quickly replaced as needed to adapt to different materials or processing requirements. And during the processing process, the blade mounting member 40 may accumulate chips, grease or other impurities. The detachable connection can make the cleaning work easier, help maintain the hygiene and performance of the equipment, and prevent impurities from damaging the blade.

[0067] It can be understood that the detachable connection between the cutter head fixing cover and the cutter head facilitates the installation and replacement of the blade, and can improve the overall processing efficiency and equipment life.

[0068] In some embodiments, as Figure 4 shown, the thickness of the second cutter head 432 is set to be adjustable.

[0069] By adjusting the thickness of the second cutter disc 432, the distance between the blades can be precisely controlled, ensuring that the cutting or processing dimensions of the pole piece meet the predetermined requirements. Moreover, since the processing characteristics of different materials are different, the requirements for the blades are also different. The adjustable thickness enables the second cutter disc 432 to be adjusted according to the processing requirements of different sizes, thereby improving the versatility and processing effect of the equipment.

[0070] An appropriate distance between the blades can make the processing process smoother and more efficient. If the blade distance is too small, the blades cannot fully cover the material, which may waste materials and time. If the blade distance is too large, multiple processes may be required to achieve the desired effect. The design with adjustable thickness can adjust the blade distance according to the actual situation, thereby optimizing the processing efficiency.

[0071] The adjustability of the thickness of the second cutter disc 432 can be achieved in various ways. For example, the second cutter disc 432 with different thicknesses can be directly replaced, or adjustable gaskets can be placed between the second cutter disc 432 and the second cutter disc fixing cover 442. By increasing or decreasing the number of gaskets or adjusting the thickness of the gaskets, the overall thickness of the second cutter disc 432 can be changed. Alternatively, a threaded adjustment mechanism can be provided on the second cutter disc 432 or the second cutter disc fixing cover 442. By rotating the threaded part, the position of the second cutter disc 432 relative to the second cutter disc fixing cover 442 can be changed, thereby adjusting the thickness of the second cutter disc 432.

[0072] It can be understood that setting the thickness of the second cutter disc 432 to be adjustable can bring higher flexibility and adaptability to the processing process. At the same time, by precisely controlling the blade distance, the processing efficiency can be optimized, which helps to improve the overall processing quality and equipment performance.

[0073] In some embodiments, the distance between the blade mounting positions of the first blade mounting member 411 and the second blade mounting member 412 is L, satisfying: 20mm ≤ L ≤ 25mm.

[0074] When L is 20mm, the distance between the blade mounting positions of the first blade mounting member 411 and the second blade mounting member 412 is relatively small. The first blade 421 and the second blade 422 can work together more closely, reducing the processing gap and improving the processing accuracy. However, the too-close distance may also increase the interference risk between the first blade 421 and the second blade 422.

[0075] When L is 22.5mm, the distance between the blade mounting positions of the first blade mounting member 411 and the second blade mounting member 412 is appropriate. The first blade 421 and the second blade 422 have neither interference risk nor can reduce the processing gap and improve the processing accuracy.

[0076] When L is 25 mm, the distance between the blade mounting positions of the first blade mounting member 411 and the second blade mounting member 412 is relatively large, and the blade can completely cover the material. There is no risk of interference between the first blade 421 and the second blade 422. However, there may be residual materials in the cutting area that are not fully cut, resulting in an increase in the surface roughness of the processed material and affecting the machining accuracy.

[0077] By adjusting the distance between the two blade mounting positions, it is possible to adapt to different sizes of processed materials and different processing requirements. When processing wider materials, the distance L can be increased to ensure that the blade can completely cover the material. When processing narrower or more delicate materials, the distance L can be reduced to improve the accuracy.

[0078] Different blade types and sizes are also applicable to different distances L. The setting of the distance L can also affect the configuration method of the blades. For example, in some applications, the two blades can be configured to rotate relative to each other to reduce vibration and improve the machining quality. In this case, the distance L will affect the interaction between the blades and the cutting effect.

[0079] It can be understood that setting the distance L between the blade mounting position of the first blade mounting member 411 and the blade mounting position of the second blade mounting member 412 in the range of 20 mm ≤ L ≤ 25 mm can meet the machining accuracy and flexibility, while ensuring the stability and reliability of the equipment.

[0080] In some embodiments, as Figure 1 and Figure 2 shown, the drive mechanism 20 includes: a power source 210, a transmission mechanism 220, and a rotating shaft 230.

[0081] The input end of the transmission mechanism 220 is power-coupled to the output end of the power source 210, the rotating shaft 230 is power-coupled to the output end of the transmission mechanism 220, and both the first blade mounting member 411 and the second blade mounting member 412 are connected to the rotating shaft 230.

[0082] The drive mechanism 20 is composed of three main parts: a power source 210, a transmission mechanism 220, and a rotating shaft 230. By working together, they provide power and drive the first blade mounting member 411 and the second blade mounting member 412 to work.

[0083] The power source 210 is responsible for generating mechanical energy or power to drive the subsequent components to move. Common power sources 210 include electric motors, engines, etc. The transmission mechanism 220 is responsible for transmitting the power generated by the power source 210 to the rotating shaft 230, and also plays roles such as decelerating, accelerating, changing the direction or form of motion, etc. The input end of the transmission mechanism 220 is power-coupled to the output end of the power source 210 to ensure that the power can be smoothly transmitted into the transmission mechanism 220. The output end of the transmission mechanism 220 is power-coupled to the rotating shaft 230, and transmits the processed power to the rotating shaft 230, thereby driving the blade mounting member 40 to work.

[0084] The rotating shaft 230 is the connection bridge between the driving mechanism 20 and the blade mounting member 40. It can receive the power from the transmission mechanism 220 and transmit it to the first blade mounting member 411 and the second blade mounting member 412, enabling them to rotate or perform other forms of motion at a predetermined speed and direction. The rotating shaft 230 is power-coupled to the output end of the transmission mechanism 220. At the same time, the first blade mounting member 411 and the second blade mounting member 412 are also connected to the rotating shaft 230 through splines so as to be able to move together with the rotating shaft 230.

[0085] When the power source 210 is started, the generated power can be transmitted to the transmission mechanism 220 through the output end. The transmission mechanism 220 processes the power and transmits the processed power to the rotating shaft 230 through the output end. After receiving the power, the rotating shaft 230 drives the connected first blade mounting member 411 and second blade mounting member 412 to move, thereby realizing cutting, grinding or other processing tasks.

[0086] It can be understood that by adjusting the parameters and configurations of the power source 210, the transmission mechanism 220 and the rotating shaft 230, the performance of the system and the processing effect can be optimized.

[0087] In some embodiments, as Figures 1-3 shown, the output end of the transmission mechanism 220 includes: a gland 240, and the rotating shaft 230 is power-coupled to the gland 240.

[0088] The gland 240, as a component of the output end of the transmission mechanism 220, is closely connected to the rotating shaft 230, which can ensure that the power can be smoothly transmitted from the transmission mechanism 220 to the rotating shaft 230. At the same time, the gland 240 can also play a role in fixing and supporting the rotating shaft 230. Through appropriate fastening and positioning designs, the gland 240 can ensure that the rotating shaft 230 remains stable during rotation and does not shift or shake.

[0089] The gland 240 can also have a sealing function to prevent the lubricating oil or other liquids inside the transmission mechanism 220 from leaking into the external environment. At the same time, the gland 240 can also provide a certain degree of protection to protect the rotating shaft 230 and the transmission mechanism 220 from impurities or contaminants in the external environment.

[0090] The dynamic coupling connection between the rotating shaft 230 and the gland 240 is usually achieved through a certain form of fasteners, such as bolts, pins, etc., or key connections, such as flat keys, splines, etc., to ensure that the rotating shaft 230 and the gland 240 maintain synchronous movement during rotation, thereby achieving effective power transmission.

[0091] When the transmission mechanism 220 receives the drive from the power source 210, it can transmit and process the power through the internal mechanism, and transmit the processed power to the rotating shaft 230 through the gland 240. After receiving the power, the rotating shaft 230 can drive the first blade mounting member 411 and the second blade mounting member 412 connected thereto to perform rotational movement, thereby achieving cutting, grinding or other processing tasks.

[0092] It can be understood that the output end of the transmission mechanism 220 includes the gland 240, which can provide a more stable and reliable power transmission method for the drive mechanism 20 and ensure the stable operation of the rotating shaft 230 and the blade mounting member 40.

[0093] In some embodiments, as Figure 1 and Figure 2 shown, the transmission mechanism 220 and the power source 210 are respectively installed on both sides of the mounting member 40.

[0094] The connection between the transmission mechanism 220 and the power source 210 through a belt is reliable and stable enough to withstand various forces and torques during operation. Distributing the transmission mechanism 220 and the power source 210 on both sides of the mounting member 40 can make more effective use of space, reduce the floor area or volume of the entire device, and the power source 210 generates heat during operation, and at the same time, components such as gears and bearings in the transmission mechanism 220 also generate heat due to friction. Separating the power source 210 and the transmission mechanism 220 for installation helps to improve the heat dissipation conditions, reduce the device temperature, and improve the operation efficiency and stability.

[0095] It can be understood that the layout of installing the transmission mechanism 220 and the power source 210 on both sides of the mounting member 40 can effectively utilize space and improve the heat dissipation conditions, thereby improving the operation efficiency and stability of the device.

[0096] The embodiment of the present application also provides a pole piece splitting device.

[0097] The pole piece splitting device includes: a tool rest 1, a first blade 421 and a second blade 422.

[0098] The first blade 421 is installed at the blade installation position of the first blade mounting member 411, and the second blade 422 is installed at the blade installation position of the second blade mounting member 412. The tool rest 1, the first blade 421, and the second blade 422 together constitute a pole piece cutting device to achieve precise cutting of the pole piece.

[0099] The tool rest 1 is the support and fixing foundation of the pole piece cutting device, used to install and position the first blade mounting member 411 and the second blade mounting member 412. The tool rest 1 has sufficient rigidity and stability to ensure that it will not deform or displace during the cutting process. The tool rest 1 may include multiple mounting holes, positioning slots, or jigs, etc., so as to accurately install and fix the blade mounting member 40. At the same time, the tool rest 1 may also have an adjustment mechanism for adjusting the relative position or angle between the blade mounting members 40 to meet the cutting requirements of pole pieces of different specifications and shapes.

[0100] The first blade mounting member 411 is an intermediate member connecting the tool rest 1 and the first blade 421, having a first blade installation position for fixing and positioning the first blade 421. It may be provided with notches or holes matching the shape and size of the blade to ensure that the blade can be firmly installed and maintained in the correct position. The first blade 421 is a key tool in the pole piece cutting process, and its shape, size, and material are selected according to the characteristics of the pole piece and the cutting requirements. The blade usually has a sharp cutting edge, which can easily penetrate the pole piece material and achieve precise cutting.

[0101] Similar to the first blade mounting member 411, the second blade mounting member 412 is also used to connect the tool rest 1 and the second blade 422, having a second blade installation position to ensure that the second blade 422 can be firmly installed and maintained in the correct position. The second blade 422 and the first blade 421 cooperate together to complete the cutting task of the pole piece.

[0102] During the pole piece cutting process, the power source 210 drives the rotating shaft 230 to rotate through the transmission mechanism 220, and then drives the first blade mounting member 411, the second blade mounting member 412, and the first and second blades mounted thereon to perform rotational or linear motion. According to the preset cutting path and speed, the first and second blades perform precise cutting on the pole piece.

[0103] It can be understood that the pole piece cutting device can achieve precise cutting of the pole piece through the coordinated work of the tool rest 1, the first blade mounting member 411, the first blade 421, the second blade mounting member 412, and the second blade 422.

[0104] The embodiment of the present application also provides a battery cell processing system.

[0105] The battery cell processing system includes: a pole piece cutting device.

[0106] The battery cell processing system integrates multiple process steps and equipment. It is a complex production system used to convert raw materials into the final battery cell products. The battery cell processing system covers multiple links from raw material preparation, electrode sheet manufacturing, battery cell assembly to performance testing. Among them, the electrode sheet cutting equipment is an important link in the electrode sheet manufacturing process, which is directly related to the performance and quality of the battery cell.

[0107] The electrode sheet cutting equipment is responsible for precisely cutting the continuous electrode sheet material according to the preset size and shape to ensure that each electrode sheet meets the requirements of battery cell assembly, which can improve the consistency and performance of the battery cell. Through the automated and precise cutting process, the electrode sheet cutting equipment can significantly improve production efficiency, reduce manual intervention and errors, and lower production costs.

[0108] The raw material processing equipment is used to mix, coat and other processes on the raw materials to make the preliminary electrode sheet material.
