Description

Technical Field

[0001] The present application relates to the field of control, and in particular, to an oven system and a method for controlling the penetration of a current collector of an oven system. Background Art

[0002] During the production process of a coating system, after applying cathode / anode slurry on a current collector, the current collector enters an oven for drying. There are various factors during the drying process that can cause the current collector to break. After the break, the machine needs to be stopped, and the current collector has to be manually bonded with tape before it can continue to operate.

[0003] In the related art, when the break occurs inside the oven, maintenance personnel need to manually pull the broken tape (the broken current collector) through the entire oven and splice the tape outside the oven. The tape splicing and resumption process is very cumbersome and time-consuming, and there are certain safety risks.

[0004] The above statements are only used to provide background technical information related to the present application, and do not necessarily constitute prior art. Summary of the Invention

[0005] One technical problem to be solved by the present application is to provide an oven system and a method for controlling the penetration of a current collector of an oven system, which can automatically pull the broken current collector through the oven, enabling rapid resumption of production and greatly reducing the potential harm to maintenance personnel.

[0006] In a first aspect, the present application provides an oven system, including: a box body, a drying chamber is arranged inside the box body, the box body has a current collector inlet and a current collector outlet communicated with the drying chamber; a traction device passing through the drying chamber; a fixing component connected to the traction device; and a controller configured to, in the case of a break in the current collector, control the coating system to push the first broken segment of the current collector to the first side outside the box body and pull the second broken segment of the current collector to the second side outside the box body, where the second side is the side opposite to the first side, and the first side or the second side is the current collector inlet side; control the traction device and the fixing component to pull the first broken segment fixed to the fixing component through the drying chamber.

[0007] In the technical solution of the embodiment of the present application, by providing a traction device passing through the drying chamber and a fixing component connected to the traction device, the traction device and the fixing component are controlled to traction the first broken section fixed to the fixing component through the drying chamber. The traction device passes through the oven, the fixing component is connected to the traction device, and through the movement of the fixing component, the broken current collector is tractioned through the oven, thereby replacing the maintenance personnel to open the oven door and perform the process of manually tractioning through the oven. Thus, the personnel and the oven system do not come into direct contact, thereby greatly reducing the probability of potential risks such as personnel being injured by high temperature, NMP (N-Methylpyrrolidone) injury, and mechanical crushing. On the other hand, since there is no need for personnel to contact the oven system, threading can be directly performed at the working temperature, eliminating the process of waiting for the oven to cool down and the oven to heat up to the working temperature, greatly shortening the downtime, also greatly reducing heat waste, and saving energy consumption.

[0008] In some embodiments, the traction device includes: a traction component, the traction component passes through the drying chamber, the traction component is parallel to the flow direction of the current collector in the drying chamber, and the traction component is connected to the fixing component; a driving component configured to drive the traction component and the fixing component to move according to a control instruction of a controller, and traction the first broken section through the drying chamber. The driving component can drive the traction component and the fixing component to move, can automatically traction the broken current collector through the oven, can achieve rapid resumption of production and greatly reduce the potential harm suffered by maintenance personnel.

[0009] In some embodiments, the oven system further includes: a label disposed at the connection position of the traction component and the fixing component; a first label sensor disposed on the second side, configured to detect the label on the traction component, wherein the controller is further configured to remove the first broken section from the fixing component and perform current collector connection on the first broken section and the second broken section when the first label sensor detects the label on the traction component. By sensing the position of the fixing component through the label sensor, the positioning of the crossbar fixing component is realized, which is convenient to remove the broken current collector from the fixing component on the tail side of the machine and perform current collector connection on the first broken section and the second broken section. Thus, by sensing the label through the label sensor, it can be accurately determined that the broken belt has moved outside the oven, so as to perform current collector connection on the first broken section and the second broken section.

[0010] In some embodiments, the controller is further configured to, after performing current collector connection on the first broken section and the second broken section, drive the traction component to move by controlling the driving component, and pull the fixing component back to the initial position on the first side, and stop the movement of the traction component. By automatically moving the fixing component back to its original position, it can prepare for the next threading (the broken current collector passes through the oven).

[0011] In some embodiments, the oven system further includes: a second label sensor disposed on the first side, wherein the second label sensor is configured to detect the label on the traction member, and the controller is further configured to determine that the fixing member has returned to the initial position on the first side and stop moving the traction member when the second label sensor detects the label on the traction member. By sensing the position of the fixing member through the label sensor, the automatic positioning of the fixing member can be realized more precisely, which is convenient for fixing the broken belt to the fixing member during the next threading.

[0012] In some embodiments, the label may be a color mark; both the first label sensor and the second label sensor are color mark sensors. In this embodiment, the position of the fixing member is sensed through the color mark sensor to realize the automatic positioning of the fixing member, which is convenient for fixing the broken belt to the fixing member. The fixing member is controlled to stay at the belt connecting position before entering the oven and the belt connecting position after exiting the oven through the color mark sensor.

[0013] In some embodiments, the controller may also be configured to drive the traction member and the fixing member to move by controlling the driving member, and traction the first broken section to pass through the drying chamber from the first side to the second side at a uniform speed. By controlling the threading speed to be uniform, the threading success rate and efficiency are improved.

[0014] In some embodiments, the fixing member may be a pull rod or a cross bar, and the setting direction of the fixing member is perpendicular to the traction member and parallel to the flow direction of the current collector. The specific composition and setting direction of the fixing member are defined, and thus the cross bar can be driven by the traction member, and the cross bar drives the broken belt, automatically realizing the current collector passing through the oven.

[0015] In some embodiments, the number of the traction members is at least one, wherein: when the number of the traction members is one, the traction member is connected to the fixing member at the middle position in the length direction of the fixing member. One traction member is connected to the fixing member at the middle position in the length direction of the fixing member. Thus, only one traction member can be used to realize the traction of the fixing member and the broken current collector.

[0016] In some embodiments, when the number of the traction members is two, the two traction members are parallel to each other, and the two traction members are connected to the fixing member at both sides in the length direction of the fixing member. Two traction members are respectively connected to the fixing member at both sides in the length direction of the fixing member. Thus, the fixing member can be jointly tractioned by the two traction members at both sides in the length direction of the fixing member, and the driving of the fixing member and the broken current collector can be realized more stably.

[0017] In some embodiments, when the number of the traction components is at least three, the at least three traction components are parallel to each other. The connection positions of two traction components and the fixed component are at both sides in the length direction of the fixed component, and the connection positions of the other traction components and the fixed component are evenly arranged between the both sides positions. By evenly arranging the connection positions of at least three traction components in the length direction of the fixed component, the fixed component can be tractioned jointly by at least three traction components in the length direction of the fixed component, so that the driving of the fixed component and the broken current collector can be realized more stably.

[0018] In some embodiments, the shape of the traction component is a closed shape. Wherein, the traction component includes a part passing through the drying chamber and a part outside the box body, and the part passing through the drying chamber and the part outside the box body form a closed shape; the traction device further includes: guide wheels, wherein each traction component bypasses at least two guide wheels. The closed traction component rotates around at least two guide wheels, so that the movement of the fixed component and the broken current collector can be conveniently tractioned by the traction component.

[0019] In some embodiments, each traction component bypasses four guide wheels to form a rectangle. The upper traction component in the rectangle passes through the drying chamber, the lower traction component in the rectangle is located at the lower side outside the box body, the left traction component in the rectangle is located at the second side outside the box body, and the right traction component in the rectangle is located at the first side outside the box body; the four guide wheels are respectively located at the four vertices of the rectangle. Starting from the guide wheel at the lower side of the second side in the clockwise direction, the four guide wheels are respectively the first guide wheel, the second guide wheel, the third guide wheel and the fourth guide wheel; the first label sensor is arranged on the second guide wheel, and the second label sensor is arranged on the third guide wheel. By defining the positions of the four guide wheels and the label sensors, and adopting the rotation of the closed rectangular traction component, the traction of the fixed component and the broken current collector can be automatically realized, and the broken current collector can be conveniently passed through the oven.

[0020] In some embodiments, the driving component includes: a tension sensor disposed on any one of at least two guide wheels around which each traction component passes, configured to detect the tension applied to the guide wheel; a driving wheel, wherein each driving wheel is respectively disposed outside a traction component and configured to drive the traction component to rotate; and a variable-frequency motor configured to drive the driving wheel to rotate, thereby driving the traction component to rotate. The controller is further configured to compare the measured value of the current tension sensor with the target tension value; in the case where the measured value of the current tension sensor is greater than the target tension value, reduce the input control value of the variable-frequency motor; in the case where the measured value of the current tension sensor is less than the target tension value, increase the input control value of the variable-frequency motor, so that the first broken section passes through the drying chamber uniformly from the first side to the second side. In this embodiment, the driving of the traction component is realized by the control method of the tension sensor, the variable-frequency motor, the driving wheel and PID (Proportional-Integral-Derivative). Specifically, the tension sensor is used to detect the control of the traction force during the traction process, and the current collector is controlled to move uniformly, greatly reducing the risk of breaking the current collector again. At the same time, through the closed-loop control of the tension and the traction speed, the traction speed can be automatically adjusted to improve the threading efficiency.

[0021] In some embodiments, the tension sensor is disposed on the guide wheel closest to the driving wheel among at least two guide wheels around which each traction component passes. By disposing the tension sensor on the guide wheel closest to the driving wheel, the control of the speed can be realized more precisely.

[0022] In some embodiments, the driving component includes: a driving wheel, wherein each driving wheel is respectively disposed outside a traction component and configured to drive the traction component to rotate; and a servo motor configured to drive the driving wheel to rotate, thereby driving the traction component to rotate. The controller is further configured to obtain the current of the servo motor, determine the actual torque value of the servo motor; compare the actual torque value with the required torque; in the case where the actual torque value is greater than the required torque, reduce the current of the servo motor; in the case where the actual torque value is less than the required torque, increase the current of the servo motor, so that the first broken section passes through the drying chamber uniformly from the first side to the second side. The driving of the traction component is realized by the control method of the servo motor, the driving wheel and PID. The driving wheel is driven by the servo motor, and the current collector is pulled through the drying chamber in a uniform speed mode. The pulling force is controlled by the servo torque feedback value. The current collector can be controlled to move uniformly, greatly reducing the risk of breaking the current collector again, automatically adjusting the traction speed, and improving the threading efficiency. At the same time, compared with the control method of the tension sensor, the variable-frequency motor, the driving wheel and PID, the process and cost of setting the tension sensor are saved.

[0023] In some embodiments, the shape of the traction member is a non-closed shape, wherein the traction member includes a portion passing through the drying chamber; the driving member includes: a first hoisting mechanism disposed on the first side; and a second hoisting mechanism disposed on the second side, wherein each traction member is connected to a first hoisting mechanism and a second hoisting mechanism; the controller is further configured to, after fixing the first broken section to the fixing member, control the second hoisting mechanism to take in the traction member, control the first hoisting mechanism to release the traction member, and traction the first broken section through the drying chamber by the traction member and the fixing member. Each traction member is connected to a hoisting mechanism on the inlet side of the current collector and a hoisting mechanism on the outlet side of the current collector. By taking in and releasing the traction member by the hoisting mechanism, a non-closed traction member can be used to realize the traction of the fixing member and the broken current collector, thereby reducing the length of the traction member and the occupation of the space outside the oven, and realizing the automatic migration of the broken current collector through the oven.

[0024] In some embodiments, the traction member is a cable or a steel cable. The cable is driven by the driving member, the cable drives the cross bar, and the cross bar drives the broken belt, and the broken belt is tractioned through the oven to realize rapid resumption of production.

[0025] In a second aspect, the present application provides a method for controlling the passage of a current collector through an oven system, including: in the case of a break in the current collector, the controller controls the coating system to push the first broken section of the current collector to the first side outside the oven body and pull the second broken section of the current collector to the second side outside the oven body, wherein the oven system includes a controller and an oven body, a drying chamber is provided in the oven body, the oven body has a current collector inlet and a current collector outlet communicating with the drying chamber, the second side is the side opposite to the first side, and the first side or the second side is the inlet side of the current collector; and the controller controls the traction device and the fixing member to traction the first broken section fixed to the fixing member through the drying chamber, wherein the oven system further includes a traction device and a fixing member, the traction device is a traction device passing through the drying chamber, and the fixing member is connected to the traction device.

[0026] In the technical solution of the embodiment of the present application, by providing a traction device passing through the drying chamber and a fixing member connected to the traction device, the traction device and the fixing member are controlled to traction the first broken section fixed to the fixing member through the drying chamber. The traction device passes through the oven, and the fixing member is connected to the traction device. By moving the fixing member, the broken current collector is tractioned through the oven, thus replacing the process of maintenance personnel opening the oven door and manually tractioning through the oven. In this way, the personnel and the oven system will not be in direct contact, thus greatly reducing the probability of potential risks such as personnel being injured by high temperature, NMP injury and mechanical injury. On the other hand, since there is no need for personnel to contact the oven system, the threading can be directly carried out at the working temperature, saving the process of waiting for the oven to cool down and the oven to heat up to the working temperature, greatly shortening the downtime, also greatly reducing the heat waste and saving the energy consumption.

[0027] In some embodiments, the controlling the traction device and the fixing member to traction the first broken section fixed to the fixing member through the drying chamber includes: the controller controls the driving member to drive the traction member and the fixing member to move, and traction the first broken section through the drying chamber, wherein the traction device includes a traction member and a driving member, the traction member passes through the drying chamber, the traction member is parallel to the current collector flow direction in the drying chamber, and the traction member is connected to the fixing member. The driving member can drive the traction member and the fixing member to move, can automatically traction the broken current collector through the oven, can realize rapid resumption of production and greatly reduce the potential injuries suffered by the maintenance personnel.

[0028] In some embodiments, the method for controlling the current collector to pass through the drying oven further includes: the controller detects the label on the traction member through the first label sensor, wherein the label is set at the connection position of each traction member and the fixing member, and the first label sensor is set on the second side; and in the case where the first label sensor detects the label on the traction member, the controller instructs to remove the first broken section from the fixing member and perform current collector connection on the first broken section and the second broken section. Thus, by the label sensor sensing the label, it can accurately determine that the broken belt has moved outside the oven, so as to perform current collector connection on the first broken section and the second broken section.

[0029] In some embodiments, the method for controlling the current collector to pass through the drying oven further includes: after performing current collector connection on the first broken section and the second broken section, the controller controls the driving member to drive the traction member to move, pulls the fixing member back to the initial position on the first side, and stops the movement of the traction member.

[0030] In some embodiments, the initial position of pulling the fixing member back to the first side includes: the controller detecting a tag on the traction member through a second tag sensor, wherein the second tag sensor is disposed on the first side; and in the case where the second tag sensor detects the tag on the traction member, the controller determines that the fixing member has returned to the initial position on the first side and stops moving the traction member. By automatically moving the fixing member back to its original position, it can prepare for the next broken current collector to pass through the oven.

[0031] In some embodiments, the controller controls the traction member and the fixing member to pull the first broken segment fixed to the fixing member through the drying chamber, including: the controller drives the traction member and the fixing member to move by controlling a driving member, and pulls the first broken segment to pass through the drying chamber from the first side to the second side at a constant speed. By controlling the tape threading speed to be constant, the success rate and efficiency of tape threading are improved.

[0032] In some embodiments, the pulling the first broken segment to pass through the drying chamber from the first side to the second side at a constant speed includes: the controller drives a driving wheel to rotate through a variable-frequency motor, and then drives the traction member to rotate, wherein the traction member is a traction member with a closed shape, the traction member includes a part passing through the drying chamber and a part outside the box body, the part passing through the drying chamber and the part outside the box body form a closed shape, and each driving wheel is respectively disposed outside one traction member; the controller detects the tension received by a guide wheel through a tension sensor, wherein each traction member bypasses at least two guide wheels, and the tension sensor is disposed on any one of the at least two guide wheels bypassed by each traction member; the controller compares the measured value of the current tension sensor with the target tension value; and in the case where the measured value of the current tension sensor is greater than the target tension value, the controller reduces the input control value of the variable-frequency motor; in the case where the measured value of the current tension sensor is less than the target tension value, the controller increases the input control value of the variable-frequency motor, so that the first broken segment passes through the drying chamber from the first side to the second side at a constant speed. By using the control method of the tension sensor, the variable-frequency motor, the driving wheel and PID to drive the traction member, specifically, the control of the traction force during the traction process is detected through the tension sensor, and the movement of the current collector is controlled at a constant speed, which greatly reduces the risk of breaking the current collector again. At the same time, through the closed-loop control of the tension and the traction speed, the traction speed can be automatically adjusted to improve the tape threading efficiency.

[0033] In some embodiments, the pulling of the first broken section through the drying chamber from the first side to the second side at a constant speed includes: the controller drives the driving wheel to rotate through the servo motor, and then drives the pulling component to rotate. Among them, the pulling component is a pulling component with a closed shape. The pulling component includes a part passing through the drying chamber and a part outside the box body. The part passing through the drying chamber and the part outside the box body form a closed shape. Each driving wheel is respectively arranged on the outside of a pulling component, and each pulling component bypasses at least two guide wheels; the controller obtains the current current of the servo motor and determines the actual torque value of the servo motor; the controller compares the actual torque value with the required torque; in the case where the actual torque value is greater than the required torque, the controller reduces the current current of the servo motor; and in the case where the actual torque value is less than the required torque, the controller increases the current current of the servo motor, so that the first broken section passes through the drying chamber from the first side to the second side at a constant speed. The driving of the pulling component is realized through the servo motor, the driving wheel and the PID control method. The driving wheel is driven by the servo motor, and the current collector is pulled through the drying chamber in a constant speed mode. The pulling force is controlled by the servo torque feedback value. The movement of the current collector can be controlled at a constant speed, greatly reducing the risk of breaking the current collector again, automatically adjusting the pulling speed, and improving the threading efficiency. At the same time, compared with the control method of the tension sensor, the frequency conversion motor, the driving wheel and the PID, the process and cost of setting the tension sensor are saved.

[0034] In some embodiments, the controller pulls the first broken section through the drying chamber through the pulling component and the fixing component, including: after fixing the first broken section to the fixing component, the controller controls the second hoisting mechanism to retract the pulling component and controls the first hoisting mechanism to release the pulling component, and pulls the first broken section through the drying chamber through the pulling component and the fixing component. Among them, the shape of the pulling component is a non-closed shape. The pulling component includes a part passing through the drying chamber. Each pulling component is connected to a first hoisting mechanism and a second hoisting mechanism. The first hoisting mechanism is arranged on the first side, and the second hoisting mechanism is arranged on the second side. By retracting and releasing the pulling component through the hoisting mechanism, a non-closed pulling component can be used to pull the fixing component and the broken current collector, so that on the basis of reducing the length of the pulling component and the occupation of the space outside the oven, the broken current collector can be automatically migrated through the oven.

[0060] In the related art, during the coating production process, the current collector needs to maintain a certain tension. In this way, there will be abnormal production situations where the current collector breaks. During the drying process of coating production, there are various factors that can cause the current collector to break. When the break occurs inside the oven, the tape connection process is as follows: 1. Close the coating valve and stop coating; 2. Stop the tape running; 3. Turn off the oven heating system; 4. Keep the oven fan on and wait for the temperature inside the oven to drop below 50°C, and the NMP concentration to be at a safe level (NMP is slightly toxic); 5. Enable the tape connection mode of the equipment and drag the front section of the broken tape outside the oven; 6. Open the oven door; 7. Enable the tape connection mode and manually pull the broken tape through the oven; 8. Bond the broken tape with tape outside the oven and resume tape running. The related art requires maintenance personnel to manually pull the broken tape through the entire oven and connect the tape outside the oven. The tape connection and resumption process is very cumbersome and time-consuming, and there are certain safety risks.

[0061] In the embodiments of the present application, by providing a traction device passing through the drying chamber and a fixing component connected to the traction device, controlling the traction device and the fixing component, the first broken section fixed to the fixing component is pulled through the drying chamber. The traction device is used to pass through the oven, the fixing component is connected to the traction device, and through the movement of the fixing component, the broken current collector is pulled through the oven, thus replacing the process in the related art where maintenance personnel open the oven door and manually pull it through the oven.

The specific composition and setting direction of the fixing member 3 are defined, and thus the cross bar can be driven by the traction member 21, and the cross bar drives the broken belt, automatically realizing the current collector passing through the oven.

[0071] As Figures 1 to 6 shown, the controller 4 is configured to, in the case of the fracture of the current collector (as Figure 3 shown), control the coating system to push the first fractured section of the current collector to the first side outside the box body and pull the second fractured section of the current collector to the second side outside the box body (as Figure 4 shown), wherein the second side is the side opposite to the first side, and the first side or the second side is the current collector inlet side; control the traction device 2 and the fixing member 3 to traction the first fractured section fixed to the fixing member 3 through the drying chamber (as Figure 5 and Figure 6 ), wherein the current collector passing direction 16 is the direction of the first fractured section from the first side to the second side.

In this embodiment, a traction device passing through a drying chamber and a fixing component connected to the traction device are provided, and the traction device and the fixing component are controlled to traction a first broken section fixed to the fixing component through the drying chamber. The traction device passes through the oven, the fixing component is connected to the traction device, and through the movement of the fixing component, the broken current collector is tractioned through the oven, thereby replacing the maintenance personnel to open the oven door and perform the process of manually tractioning through the oven. Thus, the personnel and the oven system do not come into direct contact, thereby greatly reducing the probability of potential risks such as personnel being injured by high temperature, NMP, and mechanical crushing. On the other hand, since there is no need for personnel to contact the oven system, threading can be directly performed at the working temperature, eliminating the process of waiting for the oven to cool down and heat up to the working temperature, greatly shortening the downtime, significantly reducing heat waste, and saving energy consumption.

[0076] Figure 8 Schematic diagram of an oven system according to one or more embodiments. Figure 8 is Figure 5 front view of the oven system of the Figure 1 and Figure 8 shown, the traction component 21 passes through the drying chamber, the traction component 21 is parallel to the current collector flow direction 6 in the drying chamber, and the traction component 21 is connected to the fixing component 3.

[0077] As Figure 7 shown, the driving component 22 is configured to drive the traction component 21 and the fixing component 3 to move according to the control instruction of the controller 4, and traction the first broken section through the drying chamber. In this embodiment, the driving component 22 can drive the traction component 21 and the fixing component 3 to move, thereby automatically tractioning the broken current collector through the oven, achieving rapid resumption of production and greatly reducing the potential harm suffered by maintenance personnel.

[0078] In some embodiments, the traction component 21 is a cable or a steel cable. In this embodiment, the cable can be driven by the driving component 22, the cable drives the cross bar, the cross bar drives the broken belt, and the broken belt is tractioned through the oven to achieve rapid resumption of production.

[0079] Figure 9 Schematic diagram of an oven system according to one or more embodiments. As Figure 5 , Figure 9 andFigure 10 As shown, the number of the traction components 21 is at least one, where: as Figure 9 shown, when the number of the traction components 21 is one, the traction component 21 is connected to the fixing component 3 at the middle position in the length direction of the fixing component 3. In this embodiment, one traction component 21 is connected to the fixing component 3 at the middle position in the length direction of the fixing component 3. Thus, only by one traction component 21, the traction of the fixing component 3 and the broken current collector can be realized.

[0080] In some embodiments, as Figure 5 shown, when the number of the traction components 21 is two, the two traction components 21 are parallel to each other, and the two traction components 21 are connected to the fixing component 3 at both sides in the length direction of the fixing component 3. In this embodiment, two traction components 21 are respectively connected to the fixing component 3 at both sides in the length direction of the fixing component 3. Thus, the fixing component 3 can be jointly tractioned by the two traction components 21 at both sides in the length direction of the fixing component 3, and thus the driving of the fixing component 3 and the broken current collector can be realized more stably.

[0081] Figure 10 is a schematic diagram of an oven system according to one or more embodiments. As Figure 10 shown, the number of the traction components 21 is three. When the number of the traction components 21 is at least three, the at least three traction components 21 are parallel to each other, the connection positions of two traction components 21 and the fixing component 3 are at both sides in the length direction of the fixing component 3, and the connection positions of the other traction components 21 and the fixing component 3 are evenly arranged between the both sides positions. In this embodiment, at least three traction components 21 are evenly arranged at the connection positions in the length direction of the fixing component 3. Thus, the fixing component 3 can be jointly tractioned by the at least three traction components 21 in the length direction of the fixing component 3, and thus the driving of the fixing component 3 and the broken current collector can be realized more stably.

[0082] In some embodiments, as Figure 1 、 Figure 5 、 Figures 8 to 10 shown, the oven system may further include a label 7 and a first label sensor 8.

[0083] As Figure 5 、 Figures 8 to 10 shown, the label 7 is arranged at the connection position of the traction component 21 and the fixing component 3.

[0084] As Figure 1 and Figure 8As shown, the first label sensor 8 is disposed on the second side. The first label sensor 8 is configured to detect the label 7 on the traction member 21. Wherein, the controller 4 is further configured to, when the first label sensor 8 detects the label 7 on the traction member 21, remove the first broken section from the fixing member 3 and perform current collector connection on the first broken section and the second broken section. In this embodiment, the position of the fixing member 3 is sensed by the label sensor to realize the positioning of the crossbar fixing member 3, which facilitates removing the broken current collector from the fixing member 3 on the tail side of the machine and performing current collector connection on the first broken section and the second broken section. Thus, by sensing the label 7 with the label sensor, it can be accurately determined that the broken belt has moved outside the oven, so as to perform current collector connection on the first broken section and the second broken section.

[0085] In some embodiments, the controller 4 can also be configured to, after performing current collector connection on the first broken section and the second broken section, drive the traction member 21 to move by controlling the driving member 22, pull the fixing member 3 back to the initial position on the first side, and stop the movement of the traction member 21. In this embodiment, by automatically moving the fixing member 3 back to its original position, it can prepare for the next threading (the broken current collector passes through the oven).

[0086] In some embodiments, such as Figure 1 , Figure 5 , Figures 8 to 10 As shown, the oven system may further include a second label sensor 9.

[0087] The second label sensor 9 is disposed on the first side of the box body. Wherein, the second label sensor 9 is configured to detect the label 7 on the traction member 21; the controller 4 is further configured to, when the second label sensor 9 detects the label 7 on the traction member 21, determine that the fixing member 3 has returned to the initial position on the first side and stop the movement of the traction member 21. In this embodiment, the position of the fixing member 3 is sensed by the label sensor, which can more accurately realize the automatic positioning of the fixing member 3 and facilitate fixing the broken belt to the fixing member 3 during the next threading.

[0088] In some embodiments, the label 7 may be a color mark; both the first label sensor 8 and the second label sensor 9 are color mark sensors. In this embodiment, the position of the fixing member 3 is sensed by the color mark sensor to realize the automatic positioning of the fixing member 3, which facilitates fixing the broken belt to the fixing member 3. The fixing member 3 is controlled by the color mark sensor to stay at the belt connection position before entering the oven and the belt connection position after exiting the oven.

[0089] In some embodiments, the controller 4 may also be configured to drive the traction member 21 and the fixing member 3 to move by controlling the driving member 22, so as to uniformly draw the first broken segment through the drying chamber from the first side to the second side. In this embodiment, by controlling the tape threading speed to be uniform, the success rate and efficiency of tape threading are improved.

[0090] In some embodiments, such as Figure 1 and Figure 8 shown, the shape of the traction member 21 is a closed shape, wherein the traction member 21 includes a part 211 passing through the drying chamber and an external part 212 outside the box, and the part 211 passing through the drying chamber and the external part 212 outside the box form a closed shape.

[0091] In some embodiments, such as Figure 1 , Figure 7 and Figure 8 shown, the traction device may further include: a guide wheel 23, wherein each traction member 21 bypasses at least two guide wheels 23. The closed traction member 21 rotates around at least two guide wheels 23, whereby the movement of the fixing member 3 and the broken current collector can be conveniently drawn by the traction member 21.

[0092] In some embodiments, Figure 7 the guide wheels in Figure 1 and Figure 8 embodiments may include Figure 1 and Figure 8 the first guide wheel 231, the second guide wheel 232, the third guide wheel 233 and the fourth guide wheel 234 in the embodiment. As Figure 1 and Figure 8 shown, each traction member 21 bypasses four guide wheels 23 to form a rectangle. The traction member 21 on the upper side of the rectangle passes through the drying chamber, the traction member 21 on the lower side of the rectangle is located on the lower side outside the box, the traction member 21 on the left side of the rectangle is located on the second side outside the box, and the traction member 21 on the right side of the rectangle is located on the first side outside the box; the four guide wheels 23 are respectively located at the four vertices of the rectangle. Starting from the guide wheel 23 below the second side in the clockwise direction, the four guide wheels 23 are respectively the first guide wheel 231, the second guide wheel 232, the third guide wheel 233 and the fourth guide wheel 234; the first label sensor 8 is disposed on the second guide wheel 232, and the second label sensor 9 is disposed on the third guide wheel 233. In this embodiment, the positions of the four guide wheels 23 and the label sensors are defined, and the rotation of the closed rectangular traction member 21 can automatically realize the traction of the fixing member 3 and the broken current collector 5, and the broken current collector can be conveniently passed through the oven.

[0093] In some embodiments, the driving member may include a driving wheel and a motor.

[0094] In some embodiments, the driving wheel may be a rubber roller.

[0095] In some embodiments, the traction member can be a cable or a wire rope.

[0096] In some embodiments, the fixing member can be implemented as a cross bar.

[0097] In this embodiment, two parallel traction members pass through the oven mechanism and respectively bypass four guide wheels, forming two parallel closed loops. In this embodiment, a driving wheel (rubber roller) presses on the traction member, the motor drives the rubber roller, and the driving wheel drives the traction member to move forward through friction. A fixing member is arranged between the two traction members. Outside the oven, the broken belt is fixed to the fixing member, and the broken belt is pulled through the oven by the fixing member, and the belt is spliced outside the oven, thereby enabling rapid resumption of production and greatly reducing the potential harm to maintenance personnel.

[0098] Figure 11 FIG. is a schematic diagram of a driving member according to one or more embodiments. As Figure 1 、 Figure 8 and Figure 11 shown, Figure 7 The driving member 22 of the embodiment can include: a tension sensor 221, a driving wheel 222, and a variable-frequency motor 223.

[0099] As Figure 8 shown, the tension sensor 221 is disposed on any one of at least two guide wheels 23 around which each traction member 21 passes, and is configured to detect the tension applied to the guide wheel 23.

[0100] The driving wheel 222, wherein, as Figure 1 and Figure 8 shown, each driving wheel is respectively disposed outside one traction member 21 and is configured to drive the traction member 21 to rotate.

[0101] The variable-frequency motor 223 is configured to drive the driving wheel to rotate, and further drive the traction member 21 to rotate.

[0102] The controller 4 can also be configured to compare the measured value of the current tension sensor with the target tension value; in the case where the measured value of the current tension sensor is greater than the target tension value, reduce the input control value of the variable-frequency motor; in the case where the measured value of the current tension sensor is less than the target tension value, increase the input control value of the variable-frequency motor, so that the first broken section passes through the drying chamber at a uniform speed from the first side to the second side.

[0103] In some embodiments, as Figure 11As shown, the controller 4 may include a comparison module and a PID controller module. Among them, the comparison module may be configured to compare the measured value of the current tension sensor with the target tensile force value; the PID controller module may be configured to reduce the input control value of the variable-frequency motor when the measured value of the current tension sensor is greater than the target tensile force value, and increase the input control value of the variable-frequency motor when the measured value of the current tension sensor is less than the target tensile force value, so that the first broken section passes through the drying chamber uniformly from the first side to the second side.

[0104] In this embodiment, the driving of the traction member 21 is realized by the control method of the tension sensor, the variable-frequency motor, the driving wheel and PID (Proportional-Integral-Derivative). Specifically, the tension sensor is used to detect the control of the traction force during the traction process, and the current collector is controlled to move uniformly, which greatly reduces the risk of breaking the current collector again. At the same time, the traction speed can be automatically adjusted through the closed-loop control of the tension and the traction speed, improving the threading efficiency.

[0105] In some embodiments, as Figure 1 and Figure 8 shown, the tension sensor is arranged on the guide wheel 234 closest to the driving wheel among at least two guide wheels bypassed by each traction member 21. By arranging the tension sensor on the guide wheel closest to the driving wheel, the control of the speed can be realized more precisely.

[0106] Figure 12 Schematic diagram of the driving component according to one or more embodiments. As Figure 1 and Figure 12 shown, the driving component 22 may include a driving wheel 222 and a servo motor 224.

[0107] The driving wheel 22, where each driving wheel is respectively arranged on the outside of a traction member 21 and is configured to drive the traction member 21 to rotate.

[0108] The servo motor 224 is configured to drive the driving wheel to rotate, and then drive the traction member 21 to rotate.

[0109] The controller 4 may also be configured to obtain the current current of the servo motor, determine the actual torque value of the servo motor; compare the actual torque value with the required torque; reduce the current current of the servo motor when the actual torque value is greater than the required torque; increase the current current of the servo motor when the actual torque value is less than the required torque, so that the first broken section passes through the drying chamber uniformly from the first side to the second side.

[0110] In some embodiments, as Figure 12As shown, the controller 4 may include a comparison module and a PID controller module. The comparison module may be configured to obtain the current current of the servo motor, determine the actual torque value of the servo motor, and compare the actual torque value with the required torque. The PID controller module may be configured to reduce the current current of the servo motor when the actual torque value is greater than the required torque, and increase the current current of the servo motor when the actual torque value is less than the required torque, so that the first broken section passes through the drying chamber uniformly from the first side to the second side.

[0111] In this embodiment, the driving of the traction member 21 is realized by the control method of the servo motor, the driving wheel and the PID. The driving wheel is driven by the servo motor, and the current collector is pulled through the drying chamber in a uniform speed mode, and the pulling force is controlled by the servo torque feedback value. This embodiment can control the current collector to move uniformly, greatly reducing the risk of breaking the current collector again, automatically adjusting the pulling speed, and improving the threading efficiency. At the same time, compared with the control method of the tension sensor, the frequency conversion motor, the driving wheel and the PID, the process and cost of setting the tension sensor are saved.

[0112] Figure 13 Schematic diagram of a driving component according to one or more embodiments. As Figure 13 shown, the driving component 22 may include a first hoisting mechanism 225 and a second hoisting mechanism 226.

[0113] In some embodiments, the shape of the traction member 21 is a non-closed shape, wherein the traction member 21 includes a part passing through the drying chamber; the driving component 22 includes: a first hoisting mechanism disposed on the first side; and a second hoisting mechanism disposed on the second side, wherein each traction member 21 is connected to a first hoisting mechanism and a second hoisting mechanism.

[0114] The controller 4 may further be configured to, after fixing the first broken section to the fixing member 3, control the second hoisting mechanism to take in the traction member 21, control the first hoisting mechanism to release the traction member 21, and pull the first broken section through the drying chamber through the traction member 21 and the fixing member 3. Each traction member 21 is connected to a hoisting mechanism on the current collector inlet side and a hoisting mechanism on the current collector outlet side. In this embodiment, by taking in and releasing the traction member 21 by the hoisting mechanism, the non-closed traction member 21 can be used to realize the traction of the fixing member 3 and the broken current collector. Thus, on the basis of reducing the length of the traction member 21 and reducing the occupation of the space outside the oven, the broken current collector can be automatically migrated through the oven.

[0115] In some embodiments, the traction member 21 is a cable or a steel cable. In this embodiment, the cable is driven by the driving component 22, the cable drives the cross bar, the cross bar drives the broken belt, and the broken belt is pulled through the oven to realize rapid resumption of production.

[0116] In this embodiment, the crossbar pulls the current collector, and at the working temperature environment, it passes through the oven to achieve rapid tape splicing.

[0117] In this embodiment, the color sensor is used to control the crossbar to stay at the tape splicing position before entering the oven and the tape splicing position after exiting the oven.

[0118] In this embodiment, the tape threading speed is closed-loop controlled by the tension sensor to improve the success rate and efficiency of tape threading.

[0119] In this embodiment, two groups of cables are used to pass through the oven, and a crossbar is fixed between the cables. By moving the crossbar, the broken tape is pulled through the oven, thus replacing the process of maintenance personnel opening the oven door and manually pulling it through the oven. On the one hand, this embodiment greatly reduces the direct contact between personnel and the oven system, thus greatly reducing the potential risks such as personnel being injured by high temperature, NMP, and mechanical crushing. On the other hand, because there is no need for personnel to contact the oven system, tape threading can be directly carried out at the working temperature, eliminating the process of waiting for the oven to cool down and the oven to heat up to the working temperature, greatly shortening the downtime, also greatly reducing heat waste, and saving energy consumption.

[0120] Figure 14 It is a schematic diagram of a method for controlling the current collector to pass through an oven system according to one or more embodiments. This embodiment is applied to an oven system and can be executed by the oven system or a controller. The method for controlling the current collector to pass through the oven system will be introduced in detail below. Figure 14 The embodiment may include at least one of step 100 and step 200.

[0121] Step 100, in the case of a break in the current collector, the controller controls the coating system to push the first broken segment of the current collector to the first side outside the box body and pull the second broken segment of the current collector to the second side outside the box body, where the oven system includes a controller and a box body, a drying chamber is provided inside the box body, the box body has a current collector inlet and a current collector outlet communicating with the drying chamber, the second side is the side opposite to the first side, and the first side or the second side is the current collector inlet side.

[0122] In some embodiments, step 100 may include step 110 and step 120.

[0123] Step 110, when a tape break occurs inside the oven, the tension sensor at the position where the coating equipment exits the oven detects that the tension is 0. At this time, an alarm indicating a tape break inside the oven pops up on the touch screen (as Figure 3 shown), and it is judged whether to start the automatic tape splicing mode according to user input or system braking.

[0124] Step 120: Confirm the activation of the automatic tape splicing mode. Operate the coating system to rotate forward to pull out the front part of the broken tape (the first broken section) from the oven; operate the coating system to rotate backward to push out the rear part of the broken tape (the second broken section) from the oven, as Figure 4 shown.

[0125] Step 200: The controller controls the traction device and the fixing component 3 to traction the first broken section fixed to the fixing component 3 through the drying chamber. The oven system further includes a traction device and a fixing component 3. The traction device is a traction device passing through the drying chamber, and the fixing component 3 is connected to the traction device.

[0126] In some embodiments, step 200 may include: The controller controls the driving component 22 to drive the traction component 21 and the fixing component 3 to move, and traction the first broken section through the drying chamber. The traction device includes a traction component 21 and a driving component 22. The traction component 21 passes through the drying chamber. The traction component 21 is parallel to the current direction 6 of the current collector in the drying chamber. The traction component 21 is connected to the fixing component 3. The driving component 22 can drive the traction component 21 and the fixing component 3 to move, and can automatically traction the broken current collector through the oven, which can achieve rapid resumption of production and greatly reduce the potential harm to maintenance personnel.

[0127] In the technical solution of this embodiment, by setting a traction device passing through the drying chamber and a fixing component 3 connected to the traction device, the controller controls the traction device and the fixing component 3 to traction the first broken section fixed to the fixing component 3 through the drying chamber. The traction device passes through the oven, and the fixing component 3 is connected to the traction device. Through the movement of the fixing component 3, the broken current collector is traction through the oven, thus replacing the process of maintenance personnel opening the oven door and manually traction through the oven. Therefore, the personnel and the oven system will not be in direct contact, thus greatly reducing the probability of potential risks such as high-temperature injury, NMP injury, and mechanical injury to personnel. On the other hand, because there is no need for personnel to contact the oven system, the tape splicing can be directly carried out at the working temperature, saving the process of waiting for the oven to cool down and the oven to heat up to the working temperature, greatly shortening the downtime, and also greatly reducing the heat waste and saving energy consumption.

[0128] In some embodiments, step 200 may include: The controller drives the traction component 21 and the fixing component 3 to move by controlling the driving component 22, and traction the first broken section to pass through the drying chamber uniformly from the first side to the second side. By controlling the tape splicing speed to be uniform in this embodiment, the success rate and efficiency of the tape splicing are improved.

[0129] In some embodiments, as Figure 11 shown, step 200 may include at least one of steps 210 to 240.

[0130] Step 210, the controller drives the drive wheel to rotate through the variable-frequency motor, and then drives the traction member 21 to rotate. Among them, the traction member 21 is a traction member 21 with a closed shape. The traction member 21 includes a part passing through the drying chamber and a part outside the box body. The part passing through the drying chamber and the part outside the box body form a closed shape. Each drive wheel is respectively arranged outside a traction member 21.

[0131] Step 220, the controller detects the tension received by the guide wheel 23 through the tension sensor. Among them, each traction member 21 bypasses at least two guide wheels 23, and the tension sensor is arranged on any one of the at least two guide wheels 23 bypassed by each traction member 21.

[0132] Step 230, the controller compares the measured value of the current tension sensor with the target tension value.

[0133] In some embodiments, step 230 may include: obtaining the initial threading speed input by the user; calculating the target tension value according to the initial threading speed.

[0134] In some embodiments, the actual value of the threading line speed is proportional to the output frequency value of the controller, and the measured value of the tension sensor is proportional to the actual value of the threading line speed. Thus, in this embodiment, the threading line speed is converted into frequency output.

[0135] For example: converting the line speed into frequency output, the conversion process may include: according to the frequency converter and motor parameters, when the output value of the frequency converter is 10000, the corresponding maximum speed of the motor is 1460 r / min; setting the control graduation of the PLC to 1000, that is, 1000 corresponds to the output value 1 of the frequency converter, so the PLC outputs 10000 * 1000 corresponding to the motor speed of 1460 r / min; the motor drives the rubber roller (drive wheel) to rotate through the gear set, and 1460 r / min is converted into the line speed of the rubber roller as: 1460 * 2 * r * Π / K, where K is the reduction ratio of the gear set; in summary, it can be obtained that the line speed of the rubber roller corresponding to the PLC output frequency value of 10000 * 1000 is: 1460 * 2 * r * Π / K; according to the proportional relationship between the PLC output frequency value and the line speed, VFD_SV / 10000 * 1000 = HMI_SV / (1460 * 2 * r * Π / K); it can be known that the PLC frequency output corresponding to any speed is: VFD_SV = 10000 * 1000 * HMI_SV * K / (1460 * 2 * r * Π); through the system PID function block (such as Figure 11 shown) to fine-tune the frequency, and the final output frequency: VFD_OUT is obtained.

[0136] Step 240: When the measured value of the current tension sensor is greater than the target tensile value, the controller reduces the input control value of the variable-frequency motor; when the measured value of the current tension sensor is less than the target tensile value, the controller increases the input control value of the variable-frequency motor, so that the first broken section passes through the drying chamber uniformly from the first side to the second side.

[0137] In this embodiment, the driving of the traction component 21 is realized through the control method of the tension sensor, the variable-frequency motor, the driving wheel and the PID. Specifically, the tension sensor is used to detect the control of the traction force during the traction process, and the current collector is controlled to move uniformly, which greatly reduces the risk of breaking the current collector again. At the same time, through the closed-loop control of the tension and the traction speed, the traction speed can be automatically adjusted to improve the threading efficiency.

[0138] In some embodiments, as Figure 12 shown, step 200 may include at least one of steps 250 to 280.

[0139] Step 250: The controller drives the driving wheel to rotate through the servo motor, and then drives the traction component 21 to rotate. Among them, the traction component 21 is a closed-shaped traction component 21, and the traction component 21 includes a part passing through the drying chamber and a part outside the box body. The part passing through the drying chamber and the part outside the box body form a closed shape. Each driving wheel is respectively arranged outside a traction component 21, and each traction component 21 bypasses at least two guide wheels 23.

[0140] Step 260: The controller obtains the current current of the servo motor and determines the actual torque value of the servo motor.

[0141] Step 270: The controller compares the actual torque value with the required torque.

[0142] Step 280: When the actual torque value is greater than the required torque, the controller reduces the current current of the servo motor; when the actual torque value is less than the required torque, the controller increases the current current of the servo motor, so that the first broken section passes through the drying chamber uniformly from the first side to the second side.

[0143] In some embodiments, as Figure 1 shown, the traction component can be a cable, the fixing component 3 can be a cross bar, the label 7 can be a color mark, the color mark is pasted at the position where the cable is connected to the cross bar, and the second label sensor 9 and the first label sensor 8 can be color mark sensors. In this embodiment, the servo motor drives the cable at a constant speed to drive the pull rod through the oven. The servo motor operates in torque mode. When the torque reaches the set protection value, the servo stops running, and the operator checks for abnormalities to determine whether to continue threading or re-thread.

[0144] In some embodiments, steps 250 to 280 may include: setting an initial speed and a protection torque; starting tape threading (the current collector passes through); determining whether the shaft state is normal; when the shaft state is normal, starting the pay-off reel; after a predetermined time interval elapses, starting the tape threading servo motor; determining whether the servo torque is greater than the protection torque; when the servo torque is greater than the protection torque, determining that the tape threading fails; whether the first label sensor senses a label; when the first label sensor senses a label, determining that the tape threading is successful; when the first label sensor fails to sense a label, determining that the tape threading fails; in the case of successful or failed tape threading, stopping the pay-off reel and the tape threading servo motor, and ending the tape threading.

[0145] In this embodiment, the driving of the traction member 21 is achieved through the control method of the servo motor, the driving wheel, and PID. The driving wheel is driven by the servo motor, and the current collector is pulled through the drying chamber in a uniform speed mode, and the pulling force is controlled by the servo torque feedback value. This embodiment can control the current collector to move at a uniform speed, greatly reducing the risk of breaking the current collector again, automatically adjusting the traction speed, and improving the tape threading efficiency. At the same time, compared with the control method of the tension sensor, the frequency conversion motor, the driving wheel, and PID, the process and cost of setting the tension sensor are saved.

[0146] In some embodiments, step 200 may include: as Figure 11 shown, after fixing the first broken section to the fixing member 3, the controller controls the second hoisting mechanism to retract the traction member 21, controls the first hoisting mechanism to release the traction member 21, and pulls the first broken section through the drying chamber through the traction member 21 and the fixing member 3, wherein the shape of the traction member 21 is a non-closed shape, wherein the traction member 21 includes a part passing through the drying chamber, each traction member 21 is connected to a first hoisting mechanism and a second hoisting mechanism, the first hoisting mechanism is arranged on the first side, and the second hoisting mechanism is arranged on the second side. In this embodiment, by retracting and releasing the traction member 21 through the hoisting mechanism, the non-closed traction member 21 can be used to realize the traction of the fixing member 3 and the broken current collector, so that on the basis of reducing the length of the traction member 21 and reducing the occupation of the space outside the oven, the broken current collector can be automatically migrated through the oven.

[0147] Figure 15 It is a schematic diagram of a method for controlling the passing of the current collector of an oven system according to one or more embodiments. This embodiment is applied to an oven system and can be executed by the oven system or the controller. Figure 15 In addition to including at least one of steps 100 and 200, the embodiment may further include at least one of steps 300 to 500.

[0148] Step 300, the controller detects the tag 7 on the traction member 21 through the first tag sensor 8. Herein, the tag 7 is arranged at the connection position of each traction member 21 with the fixed member 3, and the first tag sensor 8 is arranged on the second side.

[0149] Step 400, when the first tag sensor 8 detects the tag 7 on the traction member 21, the controller instructs to remove the first broken section from the fixed member 3 and perform current collector connection on the first broken section and the second broken section. Thus, by the tag sensor sensing the tag 7, it can be accurately determined that the broken belt has moved outside the oven, so as to perform current collector connection on the first broken section and the second broken section.

[0150] Step 500, after performing current collector connection on the first broken section and the second broken section, the controller drives the traction member 21 to move by controlling the driving member 22, pulls the fixed member 3 back to the initial position on the first side, and stops the movement of the traction member 21.

[0151] In some embodiments, in step 500, the step of pulling the fixed member 3 back to the initial position on the first side may include: the controller detects the tag 7 on the traction member 21 through the second tag sensor 9, wherein the second tag sensor 9 is arranged on the first side; and when the second tag sensor 9 detects the tag 7 on the traction member 21, the controller determines that the fixed member 3 has returned to the initial position on the first side and stops the movement of the traction member 21. In this embodiment, by automatically moving the fixed member 3 back to its original position, it can prepare for the current collector of the next break to pass through the oven.

[0152] In some embodiments, as Figure 1 and Figure 8 shown, the traction member may be a cable, the fixed member 3 may be a cross bar, the tag 7 may be a color mark, the color mark is pasted at the position where the cable is connected to the cross bar, the second tag sensor 9 and the first tag sensor 8 may be color mark sensors, the first side may be the machine head (current collector inlet), and the second side may be the machine tail (current collector outlet). Steps 200 to 500 may include: at the machine head, fix the rear section of the broken belt on the cross bar, and then start the driving wheel to rotate forward. The cross bar drives the current collector to pass through the oven. During the movement of the cross bar, the traveling speed is automatically adjusted according to the tension value fed back by the tension sensor. When the color mark sensor at the machine tail senses the color mark, the driving wheel stops rotating forward; at the machine tail, remove the broken belt from the cross bar and bond it with the front end of the broken belt. Then operate the driving wheel to rotate backward, and the cross bar returns to the initial position of the machine head. When the color mark sensor at the machine head position senses the color mark, the driving wheel stops rotating backward, and the automatic tape threading ends.
