Description

Technical Field

[0001] The present application relates to the technical field of membrane manufacturing, and in particular to a swing roller mechanism and a membrane manufacturing device. Background Art

[0002] In order to reduce production costs and meet increasingly stringent environmental protection requirements, dry film technology is gaining more and more attention. In the dry film manufacturing process, the film tension is relatively low after the powder is rolled into a film. During the unwinding process, the film will be wrinkled or loosely deformed due to the change in elongation. At this time, a film tension adjustment device is required for adjustment.

[0003] In the related art, the swing roller in the diaphragm tension adjustment device moves vertically, and the diaphragm is pulled up and down by the diaphragm to keep the diaphragm in a tensioned state. The up and down movement of the swing roller is completely pulled by the diaphragm. The tensile strength of the diaphragm needs to overcome the weight of the swing roller, which requires high strength of the diaphragm. The large wrap angle between the swing roller and the diaphragm increases the friction, which easily causes the diaphragm to be subjected to greater tension. Therefore, it is easy to cause the diaphragm to break for dry diaphragms. Summary of the invention

[0078] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0079] At present, the lithium battery industry mainly uses the wet slurry mixing method when preparing electrodes. The wet slurry mixing method requires high-temperature drying of solvents, consumes a lot of energy, and pollutes the environment. In order to reduce production costs and adapt to increasingly stringent environmental protection requirements, the dry diaphragm process is becoming more and more important. The dry diaphragm process is a new lithium-ion electrode manufacturing process that does not use solvents in the electrode manufacturing process. In the dry diaphragm manufacturing process, the positive and negative electrode active materials, conductive agents and solid binders are usually directly mixed to form a diaphragm. Since the diaphragm tension is small after the powder is rolled into a film, the diaphragm will be wrinkled or loosely deformed during the unwinding process due to changes in the amount of elongation. At this time, a diaphragm tension adjustment device is required for adjustment.

[0080] In the related art, the swing roller in the diaphragm tension adjustment device moves vertically, and the diaphragm is pulled up and down by the diaphragm to keep the diaphragm in a tensioned state. The up and down movement of the swing roller is completely pulled by the diaphragm. The tensile strength of the diaphragm needs to overcome the weight of the swing roller, which requires high strength of the diaphragm. The large wrap angle between the swing roller and the diaphragm increases the friction, which easily causes the diaphragm to be subjected to greater tension. Therefore, it is easy to cause the diaphragm to break for dry diaphragms.

[0081] In order to solve the above problems, the embodiment of the present application provides a new swing roller mechanism and a film making device having the swing roller mechanism, wherein the swing roller mechanism includes a swing roller assembly, and the swing roller assembly includes a driving member, a linkage assembly, a first roller and a first detection member; the driving member and the first detection member are suitable for being connected to a controller; the driving member and the first detection member are respectively connected to the linkage assembly, and the linkage assembly is also connected to the first roller; the first detection member is used to detect the position of the diaphragm transmitted between the linkage assembly and the first roller and matched with the first roller and the linkage assembly, so that the swing roller assembly can adjust the tension of the diaphragm. The embodiment of the present application can help to adjust the state of the diaphragm during the transmission process, and avoid undesirable conditions such as wrinkles, loose deformation and even breakage of the diaphragm.

[0082] The swing roller mechanism and the film-making equipment having the swing roller mechanism provided in the embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0083] Figure 1 This is a schematic diagram of the structure of the swing roller mechanism and the diaphragm provided in the embodiment of the present application. Figure 2 A schematic structural diagram of a swing roller assembly in a swing roller mechanism provided in an embodiment of the present application. Figure 3 for Figure 2 Front view of . Figure 4 for Figure 2 Top view of the . Figure 5 for Figure 2 Left view of . Figure 6 for Figure 2 Right view of . Figure 7 for Figure 2 Exploded diagram.

[0084] Reference Figure 1 As shown, the present application embodiment provides a swing roller mechanism 100, which may include a swing roller assembly 110. Specifically, see Figures 2 to 7 As shown, the swing roller assembly 110 may include a driving member 111, a linkage assembly 112, a first roller 113 and a first detection member 114, wherein the driving member 111 and the first detection member 114 are suitable for being connected to a controller.

[0085] The driving member 111 and the first detecting member 114 are respectively connected to the linkage assembly 112 , and the linkage assembly 112 is also connected to the first passing roller 113 .

[0086] In some embodiments, the driving member 111 is connected to one end of the linkage assembly 112, and the other end of the linkage assembly 112 is connected to the first detection member 114. Specifically, the driving member 111 may be drivingly connected to one end of the linkage assembly 112, the other end of the linkage assembly 112 may be fixedly connected to the first detection member 114, and the first roller 113 may be rotationally connected to the linkage assembly 112.

[0087] Alternatively, in some other embodiments, the driving member 111 and the first detecting member 114 may be connected to the same end of the linkage assembly 112 .

[0088] In the embodiment of the present application, the first detection member 114 is used to detect the position of the diaphragm 200 transmitted between the linkage assembly 112 and the first roller 113 and coordinated with the first roller 113 and the linkage assembly 112, so that the swing roller assembly 110 can adjust the tension of the diaphragm 200.

[0089] See also Figure 2 As shown, in an embodiment of the present application, the first detection member 114 may include a positioning member 1141 and a first sensor 1142, wherein the first sensor 1142 is connected to the controller, one end of the linkage assembly 112 is connected to the positioning member 1141, and when the driving member 111 drives the linkage assembly 112 to rotate, the first sensor 1142 is used to detect the position change of the positioning member 1141.

[0090] Continue to refer to Figure 2 As shown, in an embodiment of the present application, the linkage assembly 112 may include a connecting shaft 1121 and a swing roller 1122, wherein the driving member 111 is connected to one end of the connecting shaft 1121, the other end of the connecting shaft 1121 is connected to the positioning member 1141, the first roller 113 is sleeved on the connecting shaft 1121 and connected to the connecting shaft 1121, and both ends of the swing roller 1122 are connected to the connecting shaft 1121.

[0091] In some embodiments, the swing roller 1122 may be connected to the connecting shaft 1121 via a first fixing member 130 .

[0092] like Figures 3 to 6 As shown, the swing roller assembly 110 may further include a first support 117 and a first fixing plate 118. The first support 117 supports the entire swing roller assembly 110, and the first fixing plate 118 is fixed to one end of the first support 117. Figure 7 As shown, a first mounting seat 1143 is also provided on the first support 117 , and the first mounting seat 1143 is used to mount the first detection member 114 .

[0093] Continue to see Figure 7 As shown, the swing roller assembly 110 may further include a second mounting seat 119 , which is fixed to the first fixing plate 118 , and is used to mount the driving member 111 .

[0094] Figure 8 A schematic diagram of the structure of a tension assembly in a swing roller mechanism provided in an embodiment of the present application. Fig. 9 for Figure 8 Exploded diagram.

[0095] In the embodiment of the present application, the swing roller mechanism 100 may further include a tension component 120. Figure 8 and Fig. 9 As shown, the tension assembly 120 may include a second roller 121 and a second detection member 122, wherein the second detection member 122 is connected to the second roller 121. The second detection member 122 is connected to the controller. The second detection member 122 is used to detect the tension of the film 200 transmitted by the second roller 121 and matched with the second roller 121.

[0096] Continue to refer to Figure 8 and Fig. 9 As shown, the tension assembly 120 may further include a second support 123 and a second fixing plate 124. The second support 123 supports the entire tension assembly 120, and the second fixing plate 124 is fixed to one end of the second support 123. Figure 8 As shown, the second roller 121 is fixed to the second fixing plate 124 .

[0097] It can be understood that, in some embodiments, the second detection member 122 can be a second sensor. The second detection member 122 detects that the tension of the diaphragm 200 exceeds the preset range, and transmits a signal to the controller. The controller controls the driving member 111 to drive the linkage assembly 112 to swing, so as to control the tension of the diaphragm 200 to reach a suitable range. When the first sensor 1142 detects that the distance between the positioning member 1141 and the first sensor 1142 exceeds the preset value, it proves that the adjustment range of the swing roller assembly 110 has been exceeded. At this time, the signal of the first sensor 1142 is sent to the controller, and the controller controls the film forming mechanism 310 to accelerate or decelerate, so as to dynamically adjust the tension of the diaphragm 200 to be within a suitable range to prevent the diaphragm 200 from wrinkling and breaking.

[0098] In the embodiment of the present application, the position signal of the swing roller assembly 110 is fed back to the controller of the swing roller mechanism 100, and the controller controls the rotation speed of the roller in the film forming mechanism 310 and the roller in the pressure roller mechanism 320 to achieve a speed closed loop of the roller and the swing roller assembly 110. In addition, the tension of the diaphragm 200 measured by the second detection member 122 is fed back to the controller, and the controller controls the torque of the driving member 111 to achieve a torque closed loop of the tension assembly 120 and the driving member 111.

[0099] In this way, the double closed-loop method is used to actively adjust the tension of the diaphragm 200, so as to better adjust the state of the diaphragm 200 during the transmission process, avoid the diaphragm 200 from wrinkling or loose deformation due to changes in the extension amount during the transmission process, and avoid the diaphragm 200 from breaking due to changes in the transmission speed within the tension range. At the same time, it is beneficial for the cutter to be able to cut the edges of the diaphragm 200 evenly during the cutting process, thereby improving the performance of the diaphragm 200.

[0100] In the embodiments of the present application, Figures 10 to 12 As shown, the rotation center of the positioning member 1141 (ie, the rotation center A of the positioning member) and the rotation center of the connecting shaft 1121 (ie, the rotation center B of the connecting shaft) can be staggered.

[0101] In some embodiments, the shape of the positioning member 1141 may be a special-shaped member. For example, the shape of the positioning member 1141 may be as follows: Fig.11 or Fig.12 In the fan-shaped structure shown, the positioning member 1141 mainly functions to change the distance between the positioning member 1141 and the first sensor 1142 .

[0102] It should be noted that special-shaped parts refer to parts that are significantly different from traditional standard parts in terms of shape, size, structure, etc.

[0103] In the examples of this application, see Fig.11 or Fig.12 As shown, the positioning member 1141 may include a connected rotating portion 1141a, a connecting plate 1144 and an arc-shaped plate 1141d, wherein one end of the connecting plate 1144 is connected to the rotating portion 1141a, and the other end of the connecting plate 1144 is connected to the arc-shaped plate 1141d.

[0104] In a possible implementation, the connecting plate 1144 may include a first connecting plate 1141b and a second connecting plate 1141c, wherein one end of the first connecting plate 1141b is connected to the rotating portion 1141a, and the other end of the first connecting plate 1141b is connected to the arc plate 1141d. One end of the second connecting plate 1141c is connected to the rotating portion 1141a, and the other end of the second connecting plate 1141c is connected to the arc plate 1141d.

[0105] In the embodiment of the present application, a second through hole 1141f is defined on the rotating portion 1141a, and the connecting shaft 1121 may pass through the second through hole 1141f.

[0106] In addition, in some embodiments, a hollow portion 1141 e may be provided on the positioning member 1141 .

[0107] In the embodiment of the present application, the arc plate 1141d can cooperate with the first sensor 1142. Specifically, the swing amplitude of the positioning member 1141 and the outer contour shape of the arc plate 1141d facing the first sensor 1142 can match the measurement range of the first sensor 1142.

[0108] Taking the fan-shaped shape of the positioning member 1141 as an example, it can be understood that the swing amplitude of the fan-shaped positioning member 1141 and the arc surface design of the arc plate 1141d match the tension of the diaphragm 200 or the measurement range of the first sensor 1142.

[0109] Here, the closed-loop process and principle between the swing roller and the roller are introduced. After the diaphragm 200 changes, the swing roller swings and drives the positioning member 1141 to rotate. Then the first sensor 1142 receives the signal and feeds it back to the controller. If the change of the diaphragm 200 is less than the swing roller stroke range, the change of the diaphragm 200 is absorbed by the swing roller; if the change of the diaphragm 200 is greater than the swing roller stroke range, the controller controls the driving member 111 to increase or decrease speed.

[0110] Specifically, the positioning member 1141 and the swing roller simultaneously make circular motion with the connecting shaft 1121 as the center. The change in the tension of the diaphragm 200 on the swing roller causes the swing roller to make circular motion with the connecting shaft 1121 as the center. The swing roller drives the positioning member 1141 to rotate. The positioning member 1141 and the connecting shaft 1121 are eccentric structures. The second sensor detects the change in the distance between the positioning member 1141 and the second sensor to feedback the change in the position of the swing roller, so that the system can identify the position state of the diaphragm 200. When the position state of the diaphragm 200 exceeds the upper and lower limits set by the controller, the controller will control the front and rear rollers to accelerate or decelerate.

[0111] Here, the closed-loop process and principle between the swing roller and the second sensor are introduced. First, the torque reference value of the driving member 111 is set, and the second sensor detects the tension of the diaphragm 200 and feeds it back to the controller. The controller changes the output torque of the driving member 111 based on the actual tension, and then the driving member 111 adjusts the torque reference value in turn.

[0112] It should be noted here that Fig.13 As shown, the arm of the swing roller assembly is L. In the embodiment of the present application, the torque required by the diaphragm 200 is equal to the torque of the driving member 111 multiplied by the arm of the swing roller assembly L, and then multiplied by a percentage.

[0113] like Fig.14 As shown, the diaphragm 200 passes through the bottom of the second roller 121, and an upward pulling force is generated between the roller and the diaphragm 200. The second sensor can measure the magnitude and change of the tension of the diaphragm 200. Before the diaphragm 200 is transmitted, a swing force value suitable for the diaphragm 200 is set and entered into the program. When the tension detected by the second sensor is less than the set value, the controller controls the driving member 111 to increase the torque output (increase with a certain proportion of the swing force); when the second sensor detects that the tension is greater than the set value, the controller controls the driving member 111 to reduce the output torque (reduce with a certain proportion of the swing force), so that the swing force of the swing roller is stabilized near the set value.

[0114] In the embodiment of the present application, the swing roller assembly 110 may further include a weight member 115 and a second fixing member 116 , the weight member 115 is connected to one end of the second fixing member 116 , and the other end of the second fixing member 116 is connected to the connecting shaft 1121 .

[0115] The connecting shaft 1121 is also provided with a first through hole 1121a, through which the first fixing member 130 and the second fixing member 116 are connected. And / or, the first fixing member 130 and the second fixing member 116 are an integrally connected structure passing through the first through hole 1121a.

[0116] In some embodiments, there may be two second fixing members 116, and two weight members 115. The two weight members 115 are respectively connected to one end of the two second fixing members 116, and the other ends of the two second fixing members 116 are connected to the connecting shaft 1121. Similarly, the connecting shaft 1121 may be provided with two through holes 1121a.

[0117] The total weight of the two weights 115 can be the same as the weight of the swing roller 1122. The weight of the weight is the same as the weight of the swing roller 1122, and the weight can play a balancing role, so that the swing roller 1122 rotates one circle and can remain stable in space.

[0118] In the embodiment of the present application, the number of the second detecting members 122 may be two, and the two second detecting members 122 may be connected to two ends of the second roller 121 respectively.

[0119] like Fig.15 and Fig.16 As shown, in the embodiment of the present application, when the diaphragm 200 is matched with the second roller 121, a matching portion 1131 may be formed on the second roller 121, and the center angle of the matching portion 1131 on the second roller 121 (i.e., the center angle O of the matching portion) may be 10°-90°. Compared with the 180° wrap angle formed between the diaphragm 200 and the swing roller assembly 110 in the related art, the embodiment of the present application reduces the wrap angle between the diaphragm 200 and the swing roller assembly 110, thereby reducing the friction.

[0120] It should be noted that the wrap angle refers to the central angle of the contact arc between the diaphragm 200 and the roller, and the size of the wrap angle reflects the length of the contact arc between the diaphragm 200 and the roller surface. The smaller the wrap angle, the shorter the contact arc, the smaller the total friction generated between the contact surfaces, and the smaller the transmission tension of the diaphragm 200. The dry diaphragm 200 is a self-supporting film with low tension. Therefore, during the transmission process, the wrap angle between the diaphragm 200 and the roller should be minimized to reduce the tension on the diaphragm 200 and prevent the diaphragm 200 from tearing or breaking.

[0121] Illustratively, in an embodiment of the present application, the central angle of the mating portion 1131 on the second roller 121 can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90° or a range consisting of any two of them. The embodiment of the present application is not limited to this, nor is it limited to the above examples.

[0122] It should be noted here that the numerical values ​​and numerical ranges involved in this application are approximate values. Due to the influence of the manufacturing process, there may be a certain range of errors, which can be considered negligible by those skilled in the art.

[0123] In the embodiment of the present application, the swing roller 1122 may be a hollow roller. By designing the swing roller 1122 as a hollow roller, the mass of the swing roller 1122 can be reduced, thereby reducing the mass of the swing roller mechanism 100 and reducing the inertia of the swing roller when swinging.

[0124] In the embodiment of the present application, the swing roller 1122 may be made of a light material having a low density.

[0125] Similarly, the first roller 113 can be made of a light material, and the second roller 121 can also be made of a light material. Similarly, the first roller 113 can be a hollow roller, and the second roller 121 can also be a hollow roller. By designing the first roller 113 and the second roller 121 as hollow rollers, the mass of the first roller 113 and the second roller 121 can be reduced, and the mass of the swing roller mechanism 100 can be reduced, and the inertia generated by the swing roller mechanism 100 when the swing roller swings can be reduced.

[0126] In the embodiment of the present application, the lightweight material may be one or more of carbon fiber material, aluminum material or polystyrene.

[0127] In the embodiment of the present application, the length of the swing roller 1122 may be 40 mm-2000 mm. For example, the length of the swing roller may be 40 mm, 80 mm, 400 mm, 800 mm, 1200 mm, 1600 mm, 2000 mm, or a range consisting of any two of them, which is not limited in the embodiment of the present application and is not limited to the above examples.

[0128] Similarly, the length of the first roller 113 can be 40 mm-2000 mm. For example, the length of the first roller 113 can be 40 mm, 80 mm, 400 mm, 800 mm, 1200 mm, 1600 mm, 2000 mm or a range consisting of any two of them, which is not limited to the embodiments of the present application and the above examples.

[0129] The length of the second roller 121 may also be 40 mm-2000 mm. For example, the length of the second roller 121 may be 40 mm, 80 mm, 400 mm, 800 mm, 1200 mm, 1600 mm, 2000 mm, or a range consisting of any two of them, which is not limited in the embodiments of the present application and is not limited to the above examples.

[0130] In the embodiment of the present application, the cross-sectional radius of the swing roller 1122 may be 2 mm-60 mm. For example, the cross-sectional radius of the swing roller may be 2 mm, 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, or a range consisting of any two of them, and the embodiment of the present application is not limited to this, nor is it limited to the above examples.

[0131] Similarly, the cross-sectional radius of the first roller 113 may be 2 mm-60 mm. For example, the cross-sectional radius of the first roller 113 may be 2 mm, 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, or a range consisting of any two of them, which is not limited in the embodiments of the present application and is not limited to the above examples.

[0132] The cross-sectional radius of the second roller 121 may also be 2 mm-60 mm. For example, the cross-sectional radius of the second roller 121 may be 2 mm, 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, or a range consisting of any two of them, which is not limited in the present embodiment and is not limited to the above examples.

[0133] In addition, it should be noted that, see Figure 7 As shown, the two ends of the swing roller 1122 may be provided with a first bearing 1122a, and the two ends of the first roller 113 may be provided with a second bearing 113a, see Fig. 9 As shown, third bearings 121 a may be provided at both ends of the second roller 121 .

[0134] The first bearing 1122a, the second bearing 113a and the third bearing 121a can be low-damping bearings to reduce friction. For example, in some embodiments, the first bearing 1122a, the second bearing 113a and the third bearing 121a can be low-damping ceramic bearings. The density of the rolling ball of the ceramic bearing is lower than that of steel, and the weight is lighter than that of steel, so the friction of the rotation to the outer ring can be reduced. In addition, the ceramic bearing has zero corrosion, which can reduce the increase of damping during rotation caused by corrosion.

[0135] In the embodiment of the present application, the driving member 111 may be a motor, specifically, the driving member 111 may be a servo motor, for example. The servo motor includes three working modes: position mode, speed mode, and torque mode, and the choice of mode depends on the actual application scenario.

[0136] Taking the servo motor in position mode as an example, the servo motor may include a position sensor (such as an encoder), a controller, a driver, and a motor. The position sensor is used to detect the actual position of the motor shaft and convert the position signal into an electrical signal and send it to the controller. During operation, the controller sends a position command to the servo motor, and the servo motor controls the motor to reach the specified position through the internal position control system. When the motor approaches the target position, it slows down and eventually stops at the target position. The control algorithm of the servo motor in position mode usually adopts the PID (proportional-integral-differential) control algorithm. The controller calculates the position deviation based on the position command and the actual position, and then generates a control signal to control the operation of the motor through the driver to eliminate the position deviation.

[0137] Taking the servo motor in speed mode as an example, the servo motor can include a speed sensor, a controller, a driver and a motor. The speed sensor is used to detect the actual speed of the motor shaft and convert the speed signal into an electrical signal and send it to the controller. When working, the controller sends a speed command, and the servo motor controller adjusts the motor control signal according to the feedback signal to control the motor to output the specified speed. The control algorithm of the servo motor in speed mode also uses the PID control algorithm. The controller calculates the speed deviation based on the speed command and the actual speed, and then generates a control signal to control the operation of the motor through the driver to eliminate the speed deviation.

[0138] Taking the servo motor in torque mode as an example, the servo motor may include a torque sensor (or indirectly measure torque through current detection), a controller, a driver, and a motor. The torque sensor or current detection device detects the actual torque of the motor shaft and converts the torque signal into an electrical signal and sends it to the controller. When working, the controller sends a torque command, and the servo motor controller adjusts the motor control signal through the internal torque control system to control the motor to output the specified torque. The control algorithm of the servo motor in torque mode can adopt a PID control algorithm or a fuzzy control algorithm. The PID algorithm achieves precise control of the motor torque by adjusting the proportional coefficient, integral coefficient, and differential coefficient. The fuzzy control algorithm uses fuzzy logic to process the torque deviation to achieve more flexible and adaptable torque control.

[0139] In practical applications, servo motors can switch between these three modes according to the specific needs and performance requirements of the equipment to achieve different control methods and effects. At the same time, by optimizing the control algorithm and closed-loop control system, the control accuracy and stability of the servo motor can be further improved.

[0140] The motor in the swing roller mechanism adopts a servo motor to accurately control the position, speed and torque of the swing roller. The servo motor itself has the function of sending pulses. When the servo motor receives a pulse, it will rotate by an angle of a pulse to achieve displacement. Therefore, each time the servo motor rotates by an angle, it will send a corresponding number of pulses, which will form an echo with the pulse received by the servo motor, or a closed loop. In this way, the system will know how many pulses have been sent to the servo motor and how many pulses have been received back at the same time, so that the rotation of the motor can be accurately controlled, thereby achieving precise positioning, which can reach 0.0001mm. The present invention uses a servo motor for closed-loop control: in closed loop 1, the speed of the roller is controlled by the servo motor to control the rolling speed of the diaphragm 200 to remain in a stable state. That is, the speed mode of the roller servo realizes the speed closed loop. In closed loop 2, the torque of the swing roller is controlled by the servo motor to control the tension of the diaphragm 200 in a stable state, ensuring that the torque tension is within the bearing range of the diaphragm 200 to ensure that the diaphragm 200 is not torn, that is, the swing roller realizes the tension closed loop in the torque mode of the servo motor.
