[0002] Lithium ion battery is widely used in digital products, electric vehicles and energy storage fields due to high energy density, no memory effect and environmental protection advantages. However, the internal stress generated by the expansion of the pole piece during the cycle process, if not effectively released, will lead to the reduction of electrolyte, the increase of polarization, the deterioration of interface, the distortion of battery structure and the accelerated deterioration of performance, and bring safety risk. In order to solve this problem, the embossing roller is generally used to print on the surface of the pole piece, and the existing technology reserves the expansion space in the production line of the pole piece.

[0027] The preferred embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art will understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application. For example, although the following embodiments are introduced in combination with the pole piece, the embossing deviation correction mechanism and the pole piece processing device provided by the present application are also applicable to other products that need to solve the problem of poor embossing effect.

[0028] It should be noted that in the description of the present application, unless otherwise explicitly specified and limited, the terms "provided", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0029] Based on the problem of poor consistency of pole piece embossing pointed out in the background art, the present application provides an embossing deviation correction mechanism and a pole piece processing device, which aims to solve the problem of poor consistency of pole piece embossing by setting the embossing deviation correction mechanism to print and correct the pole piece, and setting the embossing deviation correction mechanism before the winding mechanism.

[0030] As shown in Figure 1 The present application provides a pole piece processing device, which comprises a unwinding mechanism 1, a guide mechanism 2, a die-cutting mechanism 3, an embossing deviation correction mechanism 4 and a winding mechanism 5. The unwinding mechanism 1, the guide mechanism 2, the die-cutting mechanism 3, the embossing deviation correction mechanism 4 and the winding mechanism 5 are sequentially arranged to make the pole piece 100 pass through in turn. The embossing deviation correction mechanism 4 is configured to simultaneously perform embossing and deviation correction on the pole piece 100 entering the embossing deviation correction mechanism 4.

[0031] The unwinding mechanism 1 is responsible for smoothly unwinding the pole piece 100 material to be embossed and feeding it into the subsequent processing flow; the guide mechanism 2 guides the pole piece 100 to advance according to the predetermined path, ensuring that the pole piece 100 does not deviate or twist during the transmission process. The die-cutting mechanism 3 performs necessary cutting or shape processing on the pole piece 100 to meet specific design requirements, the embossing deviation correction mechanism 4 is responsible for simultaneously embossing and deviation correction of the pole piece 100; the winding mechanism 5 is responsible for winding the pole piece 100 after embossing.

[0032] This invention places the embossing correction mechanism 4 with embossing function before the winding mechanism 5. Thus, after the electrode 100 is embossed by the embossing correction mechanism 4, it is directly wound by the winding mechanism 5. The embossing depth is not affected by other mechanisms (guide mechanism 2 and die-cutting mechanism 3), ensuring the consistency and stability of the embossing effect. Furthermore, while the electrode 100 is being embossed, the embossing correction mechanism 4 can also correct the deviation of the electrode 100, thereby avoiding production problems caused by the deviation of the electrode 100.

[0033] Furthermore, in the traditional electrode 100 processing flow, embossing and correction are usually two independent steps, requiring separate mechanisms. This invention integrates these two functions into the embossing and correction mechanism 4, achieving simultaneous operation. This not only reduces the equipment footprint but also lowers production costs and improves the overall efficiency of the production line.

[0034] For example, such as Figure 1 As shown, the guiding mechanism 2 of this utility model includes a serpentine correction mechanism 21 and an insert mechanism 22.

[0035] The serpentine correction mechanism 21 includes a series of rotatable rollers or guide plates arranged at specific angles and in a specific order to form a continuous deflection path. It should be noted that the specific structure of the serpentine correction mechanism 21 is prior art and will not be described in detail here. When the electrode 100 deviates during transport, the serpentine correction mechanism 21 can respond quickly, guiding the electrode 100 back onto the correct path by adjusting the angle and position of the rollers or guide plates. This mechanism not only has high flexibility but also maintains a stable correction effect when the electrode 100 is running at high speed, thus ensuring that the electrode 100 can smoothly enter the embossing correction mechanism 4, further guaranteeing the embossing effect of the electrode 100.

[0036] The insert mechanism 22 consists of a series of movable inserts that can be adjusted according to the width and thickness of the electrode 100 to ensure that the electrode 100 maintains the correct position during the embossing process. It should be noted that the specific structure of the insert mechanism 22 is prior art and will not be described in detail here.

[0037] Preferably, such as Figure 2 As shown, the embossing correction mechanism 4 includes a first roller 41, a second roller 42, and a first drive mechanism 43 arranged opposite to each other. The first roller 41 is provided with an embossing mold, so that when the first roller 41 and the second roller 42 rotate synchronously, the electrode 100 can pass between the first roller 41 and the second roller 42 to emboss the electrode 100. The first drive mechanism 43 can drive the first roller 41 and the second roller 42 to move synchronously to correct the deviation of the electrode 100.

[0038] The first roller 41 and the second roller 42 are arranged opposite each other to form an embossing channel. When the electrode 100 passes between the first roller 41 and the second roller 42, it is subjected to the action of the embossing mold, thereby forming the desired embossed pattern on the surface of the electrode 100. The embossing mold is disposed on the first roller 41. Exemplarily, the embossing mold can be a raised pattern or texture, which, when engaged with the second roller 42 (typically a flat or slightly recessed roller), can transfer the pattern or texture onto the electrode 100.

[0039] The first drive mechanism 43 is responsible for pushing the first roller 41 and the second roller 42 to translate. Through precise displacement control, the first drive mechanism 43 can fine-tune the position of the first roller 41 and the second roller 42, thereby correcting the offset of the electrode 100 during the transmission process.

[0040] Therefore, when the electrode 100 passes through the embossing and correction mechanism 4, it passes between the first roller 41 and the second roller 42. Since the first roller 41 is equipped with an embossing mold, the electrode 100 is subjected to pressure, thereby transferring the embossing pattern to its surface. This improves the embossing effect of the electrode 100 and ensures the consistency of the embossing depth. Furthermore, if the electrode 100 deviates during transport, the first drive mechanism 43 responds quickly by pushing the first roller 41 and the second roller 42 to make a slight translational adjustment, thus correcting the deviation and avoiding production problems caused by it. This adjustment is real-time, ensuring that the electrode 100 is transported along the set path.

[0041] Preferably, such as Figure 2 As shown, the embossing correction mechanism 4 also includes a bracket 44. The first roller 41 and the second roller 42 are rotatably connected to the bracket 44. The output end of the first drive mechanism 43 is connected to the bracket 44. The first drive mechanism 43 can drive the bracket 44 to move, thereby driving the first roller 41 and the second roller 42 to move synchronously.

[0042] The support frame 44 serves as the supporting structure for the entire embossing and correction mechanism 4. The support frame 44 securely connects the first roller 41 and the second roller 42, ensuring their stability and synchronization during movement. The first roller 41 and the second roller 42 are rotatably connected to the support frame 44, maintaining a relatively fixed distance to form an embossing channel. The first roller 41 is equipped with an embossing mold for forming the desired embossing pattern on the electrode 100. The second roller 42 cooperates with the first roller 41 to jointly complete the embossing process on the electrode 100.

[0043] For example, the bracket 44 in this invention is made of a robust metal material, such as steel or aluminum alloy, to withstand the forces and pressures generated during the embossing and alignment process.

[0044] The output end of the first driving mechanism 43 is connected with the support 44, and the synchronous movement of the first roller 41 and the second roller 42 is realized by driving the movement of the support 44. This design simplifies the mechanical structure, improves the stability and reliability of the system.

[0045] Preferably, as shown in the drawings, the support 44 comprises two oppositely arranged fixed plates 441, the two ends of the first roller 41 are rotatably connected with the two fixed plates 441 respectively, the two ends of the second roller 42 are rotatably connected with the two fixed plates 441 respectively, and the output end of the first driving mechanism 43 is connected with one of the fixed plates 441. Figure 2

[0046] The support 44 is composed of two oppositely arranged fixed plates 441, and the two fixed plates 441 maintain a certain distance to accommodate the installation of the first roller 41 and the second roller 42. Exemplarily, the fixed plate 441 of the utility model is a relatively thick steel plate or cast iron plate, which can provide better rigidity and stability.

[0047] The two ends of the first roller 41 and the second roller 42 are rotatably connected with the two fixed plates 441 respectively. This connection allows the pole piece 100 to pass smoothly under the roller pressure of the first roller 41 and the second roller 42, realizes printing and transmission, and at the same time maintains the stability of the first roller 41 and the second roller 42 on the support 44. Exemplarily, the rotatable connection can be realized by mechanical elements such as bearings and shaft sleeves, which are not limited in the utility model.

[0048] The output end of the first driving mechanism 43 is connected with one of the fixed plates 441. This connection allows the driving mechanism to drive the entire support 44 (including the first roller 41 and the second roller 42) to move by pushing or pulling the fixed plate 441, which can realize high-precision correction and ensure the position accuracy of the pole piece 100 in subsequent processing.

[0049] Preferably, as shown in the drawings, the support 44 further comprises a protection plate 442 arranged between the two fixed plates 441, and the protection plate 442 is provided with two protection plates 442 arranged oppositely and spaced apart, and the two fixed plates 441 and the two protection plates 442 are connected end to end to form a rectangular structure. Figure 2

[0050] By adding the protection plate 442, the overall structure of the support 44 is more stable. This helps to resist the influence of external pressure or vibration on the support 44, ensuring the stable operation of the first roller 41 and the second roller 42 in the support 44. In addition, the protection plate 442 can also provide an additional protection barrier for the first roller 41 and the second roller 42, preventing external objects or impurities from entering the inside of the embossing correction mechanism 4 and preventing the embossing correction mechanism 4 from interfering with other mechanisms, thereby ensuring the stable operation of the pole piece processing device and prolonging the service life. ​​

[0051] Preferably, as shown, the embossing deviation correction mechanism 4 further comprises a second driving mechanism 45, a slide rail is arranged on the fixed plate 441, the second roller 42 is in sliding connection with the slide rail, and the second driving mechanism 45 can drive the second roller 42 to slide on the slide rail so as to approach or move away from the first roller 41. Figure 2

[0052] The two ends of the second roller 42 in the utility model are not only in rotary connection with the fixed plate 441 but also in sliding connection with the slide rail, which makes the second roller 42 able to slide on the slide rail and thus approach or move away from the first roller 41. The slide rail arranged on the fixed plate 441 can provide accurate guidance and support for the sliding of the second roller 42.

[0053] The second roller 42 can slide on the slide rail and thus approach or move away from the first roller 41 through the driving of the second driving mechanism 45. This position adjustment function makes the embossing deviation correction mechanism 4 able to adapt to the pole piece 100 of different thicknesses so as to avoid causing excessive pressure or damage to the pole piece 100, thereby improving the embossing quality and production efficiency.

[0054] When it is necessary to process the pole piece 100 of different thicknesses, the second driving mechanism 45 is started to drive the second roller 42 to slide on the slide rail and thus adjust the distance between the first roller 41 and the second roller 42. It needs to be noted that this adjustment is real-time and can be accurately controlled according to the thickness of the pole piece 100 to ensure the embossing effect and transmission stability. After the distance is adjusted, the pole piece 100 passes between the first roller 41 and the second roller 42, and the embossing die on the first roller 41 will form the required embossing pattern on the pole piece 100. At this time, since the distance has been adjusted according to the thickness of the pole piece 100, the embossing effect is good and the pole piece 100 will not be damaged.

[0055] Exemplarily, the second driving mechanism 45 can be a motor 461, a pneumatic cylinder or a hydraulic cylinder, etc., and the type of the second driving mechanism 45 is not limited in the utility model.

[0056] Preferably, a pressure sensor (not shown in the figure) is installed on the first roller 41, the pressure sensor is in signal connection with the second driving mechanism 45, the pressure sensor can detect the pressure value of the pole piece 100, and the second driving mechanism 45 can drive the second roller 42 to approach or move away from the first roller 41 to adjust the distance between the second roller 42 and the first roller 41.

[0057] The pressure sensor is installed on the first roller 41 and is used to detect the pressure value of the pole piece 100 in the embossing process in real time. Exemplarily, the pressure sensor can be strain gauge type, capacitance type or piezoresistance type, etc., and the specific type of the pressure sensor depends on the required measurement range, accuracy and response time, etc., and the specific type of the pressure sensor is not limited in the utility model. ​

[0058] The pressure sensor is connected with the second driving mechanism 45, so that the control system processes and analyzes the received pressure data to determine whether the distance between the second roller 42 and the first roller 41 needs to be adjusted. According to the data of the pressure sensor, the second driving mechanism 45 can dynamically adjust the position of the second roller 42 on the slide rail, so as to change the distance between the second roller 42 and the first roller 41. In this way, it can ensure that the pole piece 100 maintains a stable pressure and tension state during the embossing process, thereby improving the embossing precision and product quality. Moreover, by adjusting the position of the second roller 42, it can process pole pieces 100 of different thicknesses and materials, and can also adapt to the change of the pressure of the pole piece 100 during the embossing process, thereby ensuring the consistency and stability of the embossing effect.

[0059] Preferably, as shown in Figure 2 The embossing correction mechanism 4 further comprises a third driving mechanism 46, the rotary output end of the third driving mechanism 46 is connected with the first roller 41, and the third driving mechanism 46 can drive the first roller 41 to rotate to convey the pole piece 100 and emboss the pole piece 100.

[0060] The third driving mechanism 46 is the power source of the first roller 41, and the rotary output end thereof is connected with the first roller 41 to drive the first roller 41 to rotate.

[0061] Exemplarily, as shown in Figure 2 The third driving mechanism 46 of the utility model comprises a motor 461, a shaft coupling 462 and a transmission shaft 463, the input end of the shaft coupling 462 is connected with the rotary output shaft of the motor 461, the output end of the shaft coupling 462 is connected with the transmission shaft 463, after the motor 461 is started, the output shaft thereof drives the input shaft of the shaft coupling 462 to rotate, the shaft coupling 462 reduces the rotating speed of the motor 461 through the transmission elements such as gears or worm gears inside, and increases the output torque at the same time. The output shaft of the shaft coupling 462 transmits the increased torque to the transmission shaft 463, and the transmission shaft 463 further transmits the torque to the first roller 41. In this way, the first roller 41 can rotate at the required rotating speed and torque.

[0062] Therefore, the third driving mechanism 46 of the utility model not only can provide unidirectional driving force, but also has the ability to apply positive and negative torque. When the motor 461 rotates in the normal direction, the torque generated thereby is used to drive the normal operation of the first roller 41, so as to ensure that the pole piece 100 can smoothly pass through the first roller 41 and obtain the required embossing effect.

[0063] Further, during the winding process of the winding mechanism 5, if the speed of the winding mechanism 5 is lower than the speed of the unwinding mechanism 1, it will cause the pole piece 100 to accumulate excessive tension between the two. In order to avoid the damage of the pole piece 100 caused by excessive tension or production problems, a reverse torque is provided by the third driving mechanism 46, which will slow down or temporarily stop the unwinding speed of the unwinding mechanism 1, while increasing the winding speed of the winding mechanism 5, so as to adjust and stabilize the tension. In this way, the tension of the pole piece 100 can be ensured to remain at a stable and true level, preventing the pole piece 100 from being damaged due to excessive tension, thereby improving production efficiency and product quality.

[0064] Preferably, the embossing deviation correction mechanism 4 further comprises a tension detection mechanism (not shown in the figure), which is arranged before the embossing deviation correction mechanism 4, and is signal connected with the third driving mechanism 46. The tension detection mechanism can detect the tension data of the pole piece 100 during transmission, and the third driving mechanism 46 can adjust its rotation speed according to the tension data.

[0065] The tension detection mechanism and the third driving mechanism 46 are signal connected. Thus, the tension detection mechanism can transmit the detected tension data to the third driving mechanism 46 in real time, and the third driving mechanism 46 can quickly respond according to the data. When the tension detection mechanism detects that the tension of the pole piece 100 exceeds the preset range, it will send a signal to the third driving mechanism 46. The third driving mechanism 46 will then adjust its rotation speed according to the received tension data, so as to slow down or speed up the transmission speed of the pole piece 100, thereby realizing dynamic adjustment of the tension.

[0066] For example, the embossing deviation correction mechanism 4 in the utility model further comprises a controller, and the tension detection mechanism and the third driving mechanism 46 are signal connected with the controller. During the transmission of the pole piece 100, the tension detection mechanism continuously monitors the tension data and sends the real-time tension data to the controller. The controller, as the "brain" of the whole system, receives the tension data from the tension detection mechanism and analyzes and processes these data according to the preset algorithm or logic. If the current tension data exceeds the normal range or reaches a certain threshold value, the controller will trigger the corresponding adjustment mechanism. According to the analysis result of the tension data, the controller will send specific rotation speed adjustment instructions to the third driving mechanism 46, and the third driving mechanism 46 will immediately adjust its rotation speed to respond to the change of the tension, so as to maintain the stable transmission and tension balance of the pole piece 100. For example, when the tension data indicates that the tension of the pole piece 100 is too large, the third driving mechanism 46 will reduce the rotation speed to reduce the conveying speed of the pole piece 100, thereby reducing the tension; on the contrary, when the tension data indicates that the tension of the pole piece 100 is too small, the third driving mechanism 46 will increase the rotation speed to increase the conveying speed of the pole piece 100, thereby increasing the tension.

[0067] By monitoring and adjusting the tension of the pole piece 100 in real time, the embossing deviation correction mechanism 4 can ensure that the pole piece 100 maintains a stable tension state during the embossing process, thereby ensuring that the winding tension is consistent with the set tension.

[0068] Preferably, the tension detection mechanism includes a tension over roller (not shown in the figure) and a tension sensor (not shown in the figure) installed on the tension over roller, the pole piece 100 is wound on the tension over roller, and the tension sensor is signal connected with the third driving mechanism 46, which can adjust its rotation speed according to the feedback signal of the tension sensor to slow down or speed up the transmission speed of the pole piece 100.

[0069] The tension over roller is a key component in the transmission path of the pole piece 100. The pole piece 100 is wound on the tension over roller and is transmitted with the rotation of the over roller. When the pole piece 100 passes through, the tension over roller can sense and respond to the tension change of the pole piece 100, so as to accurately reflect the tension state of the pole piece 100. The tension sensor is installed on the tension over roller for real-time monitoring of the tension change of the pole piece 100 during transmission. The sensor indirectly measures the tension by sensing the degree of compression or deformation of the pole piece 100 on the over roller. These measurement data are then converted into electrical signals and transmitted to the control system.

[0070] Illustratively, the tension sensor can be a strain gauge, a pressure sensor or a magnetostrictive sensor, etc., which can monitor the force of the pole piece 100 on the tension over roller in real time and convert it into an electrical signal.

[0071] Illustratively, the tension sensor and the third driving mechanism 46 are both signal connected with the controller. During the transmission of the pole piece 100, the tension sensor continuously monitors the tension generated by the pole piece on the tension over roller and converts the real-time tension data into electrical signals, which are transmitted to the controller through signal lines. After receiving the electrical signals transmitted by the tension sensor, the controller processes them, and then compares the processed tension data with the preset tension range or threshold value. If the current tension data exceeds the normal range or reaches a certain threshold value, the controller will trigger the rotation speed adjustment mechanism.

[0072] According to the analysis result of the tension data, the controller will send specific rotation speed adjustment instructions to the third driving mechanism 46. After receiving the instructions from the controller, the third driving mechanism 46 will immediately adjust its rotation speed. For example, if the tension is too large, the third driving mechanism 46 will reduce the rotation speed to slow down the transmission speed of the pole piece, thereby reducing the tension; if the tension is too small, the third driving mechanism 46 will increase the rotation speed to speed up the transmission speed of the pole piece, thereby increasing the tension.

[0073] By the combination of tension over rollers and tension sensors, the tension of the pole piece 100 during transmission can be accurately measured and controlled. This precise control helps to avoid the problem of the pole piece 100 being damaged due to excessive tension, or being loose due to insufficient tension. In addition, the tension detection mechanism can respond to the tension change of the pole piece 100 in real time, and adjust the rotation speed of the third driving mechanism 46 accordingly. So that the embossing correction mechanism 4 can operate more stably, and reduce the production problems caused by tension fluctuations.

[0074] So far, the technical scheme of the utility model has been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the utility model is obviously not limited to these specific embodiments. Without deviating from the principles of the utility model, those skilled in the art can make equivalent changes or replacements to related technical features, and the technical schemes after these changes or replacements will fall within the protection scope of the utility model.
