Description

Oven system and oven system current collector penetration control method

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on November 17, 2023, with application number 202311541373.5 and invention name “Oven system and oven system collector passing control method”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of control, and in particular to an oven system and a method for controlling current collector penetration in the oven system. Background Art

[0003] During the coating system production process, after the cathode / anode slurry is applied to the current collector, it enters an oven for drying. Various factors can cause the current collector to break during the drying process, requiring the system to be shut down and manually reattached with tape before continued operation.

[0004] In the prior art, if a break occurs inside the oven, maintenance personnel must manually pull the broken ribbon (the broken current collector) through the entire oven and reconnect it outside. This reconnection process is cumbersome and time-consuming, and poses certain safety risks.

[0005] The above statements are only used to provide background information related to the present application and do not necessarily constitute prior art.

[0006] Application Contents

[0007] A technical problem to be solved by the present application is to provide an oven system and an oven system current collector penetration control method, which can automatically pull the broken current collector through the oven, thereby quickly resuming production and greatly reducing potential injuries to maintenance personnel.

[0008] In the first aspect, the present application provides an oven system, comprising: a box body, a drying chamber is provided in the box body, and the box body has a collector inlet and a collector outlet connected to the drying chamber; a traction device passing through the drying chamber; a fixing component connected to the traction device; and a controller, which is configured to control the coating system to push the first broken segment of the collector to the first side outside the box and pull the second broken segment of the collector to the second side outside the box when the collector is broken, wherein the second side is the side in the opposite direction of the first side, and the first side or the second side is the 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.

[0009] In the technical solution of the embodiment of the present application, a traction device passing through the drying chamber and a fixed component connected to the traction device are provided, and the traction device and the fixed component are controlled to pull the first broken segment fixed to the fixed component through the drying chamber. A traction device is used to pass through the oven, and the fixed component is connected to the traction device. The broken current collector is pulled through the oven by the movement of the fixed component, thereby replacing the process of maintenance personnel opening the oven door and manually pulling it through the oven. In this way, there is no direct contact between personnel and the oven system, which greatly reduces the probability of potential risks such as high temperature injury, NMP (N-Methylpyrrolidone, N-methylpyrrolidone) injury and structural injury. On the other hand, because there is no need for personnel to contact the oven system, the belt can be threaded directly 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, and greatly reducing heat waste and saving energy consumption.

[0010] In some embodiments, the pulling device includes: a pulling component, which passes through the drying chamber, is parallel to the flow direction of the current collector within the drying chamber, and is connected to the fixing component; and a driving component, configured to drive the pulling component and the fixing component to move according to control instructions from a controller, thereby pulling the first broken segment through the drying chamber. The driving component can drive the pulling component and the fixing component to move, automatically pulling the broken current collector through the drying oven, thereby quickly resuming production and significantly reducing potential harm to maintenance personnel.

[0011] In some embodiments, the oven system further comprises: a tag disposed on the traction member at a location where it connects to the fixing member; and a first tag sensor disposed on the second side, configured to detect the tag on the traction member. The controller is further configured to, upon detection of the tag on the traction member by the first tag sensor, remove the first broken segment from the fixing member and perform a current collector connection between the first and second broken segments. The tag sensor senses the position of the fixing member to position the crossbar fixing member, facilitating removal of the broken current collector from the fixing member at the tail end of the machine and current collector connection between the first and second broken segments. Thus, by sensing the tag with the tag sensor, it is possible to accurately determine that the broken belt has moved outside the oven, allowing for current collector connection between the first and second broken segments.

[0012] In some embodiments, the controller is further configured to, after the first and second broken segments are connected to the current collector, control the driving component to drive the traction component to move, pull the fixing component back to its original position on the first side, and stop the movement of the traction component. By automatically moving the fixing component back to its original position, preparations can be made for the next threading (passing the broken current collector through the oven).

[0013] In some embodiments, the oven system further includes a second tag sensor disposed on the first side, wherein the second tag sensor is configured to detect a tag on the traction member. The controller is further configured to, upon detection of the tag on the traction member by the second tag sensor, determine that the fixing member has returned to its initial position on the first side and stop moving the traction member. By sensing the position of the fixing member with the tag sensor, the fixing member can be more accurately positioned automatically, facilitating the fixing of a broken tape to the fixing member during the next threading operation.

[0014] In some embodiments, the label may be a color code; both the first and second label sensors are color code sensors. This embodiment uses the color code sensor to sense the position of the fixing component, enabling automatic positioning of the fixing component and facilitating the fixing of a broken tape to the fixing component. The color code sensor controls the fixing component to remain at the splicing position before entering the oven and at the splicing position after exiting the oven.

[0015] In some embodiments, the controller can be further configured to control the driving component to drive the traction component and the fixing component to move, thereby pulling the first broken segment from the first side to the second side through the drying chamber at a constant speed. By controlling the threading speed to be constant, the threading success rate and efficiency are improved.

[0016] In some embodiments, the fixing member may be a pull rod or a cross bar, and the fixing member is positioned perpendicular to the traction member and parallel to the flow direction of the current collector. By defining the specific composition and orientation of the fixing member, the traction member can drive the cross bar, which in turn drives the belt, automatically allowing the current collector to pass through the oven.

[0017] In some embodiments, the number of the pulling member is at least one, wherein: when there is only one pulling member, the pulling member is connected to the fixing member at a mid-position along the length of the fixing member. By using one pulling member connected to the fixing member at a mid-position along the length of the fixing member, the fixing member and the broken current collector can be pulled by only one pulling member.

[0018] In some embodiments, when there are two traction members, the two traction members are parallel to each other and connected to the fixing member at both sides of the length direction of the fixing member. By using two traction members connected to the fixing member at both sides of the length direction of the fixing member, the fixing member can be pulled together by the two traction members on both sides of the length direction of the fixing member, thereby more stably driving the fixing member and the broken current collector.

[0019] In some embodiments, when there are at least three traction members, the at least three traction members are parallel to each other, two traction members are connected to the fixed member at positions on both sides of the length direction of the fixed member, and the connection positions of the other traction members to the fixed member are evenly arranged between the two sides. By evenly arranging the connection positions of the at least three traction members along the length direction of the fixed member, the fixed member can be pulled by the at least three traction members along the length direction of the fixed member, thereby more stably driving the fixed member and the broken current collector.

[0020] In some embodiments, the traction member is shaped like a closed shape, wherein the traction member includes a portion that passes through the drying chamber and a portion outside the cabinet, and the portion that passes through the drying chamber and the portion outside the cabinet form a closed shape. The traction device further includes guide wheels, wherein each traction member passes around at least two guide wheels. The closed traction member rotates around the at least two guide wheels, thereby facilitating the movement of the fixing member and the broken current collector by the traction member.

[0021] In some embodiments, each traction member wraps around four guide wheels to form a rectangle. The upper traction member of the rectangle passes through the drying chamber, the lower traction member of the rectangle is located outside the drying chamber, the left traction member of the rectangle is located on the second side outside the drying chamber, and the right traction member of the rectangle is located on the first side outside the drying chamber. The four guide wheels are located at the four vertices of the rectangle. Starting from the guide wheel at the lower side of the second side, the four guide wheels are clockwise, namely the first guide wheel, the second guide wheel, the third guide wheel, and the fourth guide wheel. The first tag sensor is located on the second guide wheel, and the second tag sensor is located on the third guide wheel. By defining the positions of the four guide wheels and the tag sensors, the closed rectangular traction member can be rotated to automatically pull the fixed member and the broken current collector, thereby conveniently passing the broken current collector through the drying oven.

[0022] In some embodiments, the driving component includes: a tension sensor, which is arranged on any one of the at least two guide wheels that each traction component passes around, and is configured to detect the tension exerted on the guide wheel; a driving wheel, wherein each driving wheel is respectively arranged on the outside of a traction component, and is configured to drive the traction component to rotate; a variable frequency motor, which is configured to drive the driving wheel to rotate, and then drive the traction component to rotate, wherein the controller is further configured to compare the current measurement value of the tension sensor with the target tension value; when the current measurement value of the tension sensor is greater than the target tension value, reduce the input control value of the variable frequency motor; when the current measurement value of the tension sensor is less than the target tension value, increase the input control value of the variable frequency motor, so that the first breaking segment passes through the drying chamber at a uniform speed from the first side to the second side. This embodiment drives the traction component through a tension sensor, a variable frequency motor, a drive wheel and a PID (Proportional-Integral-Derivative) control method. Specifically, the tension sensor detects the control of the traction force during the traction process and controls the uniform movement of the current collector, which greatly reduces the risk of the current collector being broken again. At the same time, the traction speed can be automatically adjusted through closed-loop control of the tension and traction speed to improve the threading efficiency.

[0023] In some embodiments, the tension sensor is disposed on the guide wheel closest to the driving wheel among the at least two guide wheels around which each traction member passes. By disposing the tension sensor on the guide wheel closest to the driving wheel, speed control can be achieved more accurately.

[0024] In some embodiments, the drive components include: drive wheels, each of which is disposed on the outside of a traction component and configured to drive the traction component to rotate; and servo motors configured to rotate the drive wheels, thereby driving the traction component. The controller is further configured to obtain a current current of the servo motor, determine an actual torque value of the servo motor, compare the actual torque value with a desired torque, and reduce the current current of the servo motor if the actual torque value exceeds the desired torque; and increase the current current of the servo motor if the actual torque value is less than the desired torque, thereby causing the first broken segment to pass through the drying chamber at a constant speed from the first side to the second side. The traction components are driven by a servo motor, drive wheels, and PID control method. The drive wheels are driven by the servo motors and pull the current collector through the drying chamber at a constant speed. The pulling force is controlled by servo torque feedback. This allows the current collector to move at a constant speed, significantly reducing the risk of further breakage, automatically adjusting the pulling speed, and improving threading efficiency. Furthermore, compared to control methods that require a tension sensor, a variable frequency motor, drive wheels, and PID, this method reduces the process and cost of setting up a tension sensor.

[0025] In some embodiments, the traction component is in a non-closed shape, wherein the traction component includes a portion that passes through the drying chamber; the driving component includes: a first hoisting mechanism provided on the first side; and a second hoisting mechanism provided on the second side, wherein each traction component is connected to a first hoisting mechanism and a second hoisting mechanism; the controller is further configured to control the second hoisting mechanism to retract the traction component and control the first hoisting mechanism to release the traction component after the first broken segment is fixed to the fixed component, thereby pulling the first broken segment through the drying chamber through the traction component and the fixed component. Each traction component 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 retracting and releasing the traction component through the hoisting mechanism, a non-closed traction component can be used to achieve traction of the fixed component and the broken current collector, thereby achieving the automatic migration of the broken current collector through the oven while reducing the length of the traction component and the space occupied outside the oven.

[0026] In some embodiments, the traction component is a cable or a steel cable. The driving component drives the cable, the cable drives the cross bar, the cross bar drives the broken belt, and the broken belt is pulled through the oven to quickly resume production.

[0027] In a second aspect, the present application provides a method for controlling the passage of a current collector in an oven system, comprising: in the event that the current collector is broken, the controller controls the coating system to push the first broken segment of the current collector to the first side outside the box, and pulls the second broken segment of the current collector out to the second side outside the box, wherein the oven system comprises a controller and a box body, a drying chamber is provided in the box body, the box body has a current collector inlet and a current collector outlet connected to the drying chamber, the second side is the side in the opposite direction of the first side, and the first side or the second side is the current collector inlet side; and the controller controls the traction device and the fixing component to pull the first broken segment fixed to the fixing component through the drying chamber, wherein the oven system further comprises a traction device and a fixing component, the traction device is a traction device that passes through the drying chamber, and the fixing component is connected to the traction device.

[0028] In the technical solution of the embodiment of the present application, a traction device passing through the drying chamber and a fixed component connected to the traction device are provided, and the traction device and the fixed component are controlled to pull the first broken segment fixed to the fixed component through the drying chamber. A traction device is used to pass through the oven, and the fixed component is connected to the traction device. The broken current collector is pulled through the oven by the movement of the fixed component, thereby replacing the process of maintenance personnel opening the oven door and manually pulling it through the oven. In this way, there is no direct contact between personnel and the oven system, which greatly reduces the probability of potential risks such as high temperature injury, NMP injury, and structural injury to personnel. On the other hand, because there is no need for personnel to contact the oven system, the belt can be threaded directly 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, and greatly reducing heat waste and saving energy consumption.

[0029] In some embodiments, controlling the traction device and the fixing component to pull the first broken segment fixed to the fixing component through the drying chamber includes: a controller controlling a driving component to drive the traction component and the fixing component to move, thereby pulling the first broken segment through the drying chamber, wherein the traction device includes a traction component and a driving component, the traction component passing through the drying chamber, the traction component being parallel to the flow direction of the current collector within the drying chamber, and the traction component being connected to the fixing component. The driving component can drive the traction component and the fixing component to move, thereby automatically pulling the broken current collector through the drying oven, thereby quickly resuming production and significantly reducing potential harm to maintenance personnel.

[0030] In some embodiments, the drying oven current collector passage control method further includes: a controller detecting a label on a traction member using a first label sensor, wherein the label is provided at the connection location between each traction member and the fixing member, and the first label sensor is provided on the second side; and when the first label sensor detects the label on the traction member, the controller instructs the first broken segment to be removed from the fixing member and the first broken segment to be connected to the second broken segment. Thus, by sensing the label with the label sensor, it is possible to accurately determine that the broken segment has moved outside the drying oven, so that the first broken segment and the second broken segment can be connected to the current collector.

[0031] In some embodiments, the drying box collector passing control method also includes: after the first broken segment and the second broken segment are connected to the collector, the controller controls the driving component to drive the traction component to move, pulls the fixing component back to the initial position of the first side, and stops the movement of the traction component.

[0032] In some embodiments, pulling the fixing member back to its initial position on the first side includes: the controller detecting a label on the traction member using a second label sensor, wherein the second label sensor is disposed on the first side; and when the second label sensor detects the label on the traction member, the controller determines that the fixing member has returned to its initial position on the first side and stops moving the traction member. Automatically returning the fixing member to its initial position prepares the next broken current collector for passage through the oven.

[0033] In some embodiments, the controller controls the pulling member and the fixing member to pull the first broken segment fixed to the fixing member through the drying chamber, including: the controller controls the driving member to drive the pulling member and the fixing member to move, thereby pulling the first broken segment from the first side to the second side through the drying chamber at a constant speed. By controlling the threading speed to be constant, the threading success rate and efficiency are improved.

[0034] In some embodiments, the pulling of the first broken segment through the drying chamber at a uniform speed from the first side to the second side includes: the controller drives the driving wheel to rotate through the variable frequency motor, and then drives the traction component to rotate, wherein the traction component is a closed-shaped traction component, and the traction component includes a part passing through the drying chamber and a part outside the box, and the part passing through the drying chamber and the part outside the box form a closed shape, and each driving wheel is respectively arranged on the outside of a traction component; the controller detects the tension applied to the guide wheel through a tension sensor, wherein each traction component bypasses at least two guide wheels, and the tension sensor is arranged on any one of the at least two guide wheels bypassed by each traction component; the controller compares the current measurement value of the tension sensor with the target tension value; and when the current measurement value of the tension sensor is greater than the target tension value, the controller reduces the input control value of the variable frequency motor; when the current measurement value of the 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 at a uniform speed from the first side to the second side. The traction components are driven by a tension sensor, a variable frequency motor, a drive wheel and a PID control method. Specifically, the traction force is detected by the tension sensor during the traction process, and the current collector is controlled to move at a uniform speed, which greatly reduces the risk of the current collector being broken again. At the same time, the traction speed can be automatically adjusted through closed-loop control of the tension and traction speed to improve the threading efficiency.

[0035] In some embodiments, pulling the first broken segment through the drying chamber at a constant speed from the first side to the second side includes: a controller driving a drive wheel via a servo motor to rotate, thereby driving a pulling component to rotate, wherein the pulling component is a closed-shaped pulling component, comprising a portion passing through the drying chamber and a portion outside the casing, the portion passing through the drying chamber and the portion outside the casing forming a closed shape, each drive wheel being disposed on the outside of a pulling component, and each pulling component passing around at least two guide wheels; a controller obtaining a current current of the servo motor and determining an actual torque value of the servo motor; the controller comparing the actual torque value with a required torque; if the actual torque value is greater than the required torque, the controller reducing the current current of the servo motor; and if the actual torque value is less than the required torque, the controller increasing the current current of the servo motor, thereby causing the first broken segment to pass through the drying chamber at a constant speed from the first side to the second side. The pulling component is driven by a servo motor, a drive wheel, and a PID control method, wherein the drive wheel is driven by the servo motor, and the current collector is pulled through the drying chamber at a constant speed, with the pulling force controlled by the servo torque feedback value. This allows the current collector to move at a constant speed, significantly reducing the risk of the current collector breaking again, automatically adjusting the pulling speed, and improving threading efficiency. At the same time, compared with the control method of tension sensor, frequency conversion motor, drive wheel and PID, it saves the process and cost of setting up tension sensor.

[0036] In some embodiments, the controller pulls the first broken segment through the drying chamber via the traction member and the fixing member, including: after the first broken segment is fixed to the fixing member, the controller controls the second hoisting mechanism to retract the traction member and controls the first hoisting mechanism to release the traction member, and pulls the first broken segment through the drying chamber via the traction member and the fixing member, wherein the traction member is non-closed in shape, wherein the traction member includes a portion that passes through the drying chamber, each traction member 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 traction member via the hoisting mechanism, the non-closed traction member can be used to achieve traction of the fixing member and the broken current collector, thereby achieving automatic migration of the broken current collector through the oven while reducing the length of the traction member and the space occupied outside the oven.

[0061] In order to make the purpose, technical solutions and technical effects of this application more clear, this application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0062] In the related art, during the coating production process, the current collector needs to maintain a certain tension. This will lead to the production anomaly of the current collector breaking. There are many factors in the drying process of coating production that will cause the current collector to break, and when the break occurs inside the oven, the splicing process is as follows: 1. Close the coating valve and stop coating; 2. Stop the tape; 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° and the NMP concentration to be at a safe level (NMP is slightly toxic); 5. The equipment enables the splicing mode and drags the front section of the broken tape outside the oven; 6. Open the oven door; 7. Enable the splicing mode and manually pull the broken tape through the oven; 8. Use tape to bond the broken tape outside the oven and resume tape running. The related technology requires maintenance personnel to manually pull the broken tape through the entire oven and splice it outside the oven. The splicing and resumption process is very cumbersome and time-consuming, and there are certain safety risks.

[0063] In the embodiments of the present application, a pulling device is provided that passes through the drying chamber, and a fixing member is connected to the pulling device. The pulling device and the fixing member are controlled to pull the first broken segment fixed to the fixing member through the drying chamber. The pulling device is used to pass through the drying oven, and the fixing member is connected to the pulling device. The fixed member is moved to pull the broken current collector through the drying oven, thereby replacing the process of technical maintenance personnel opening the oven door and manually pulling the broken current collector through the drying oven.

[0065] The coating system 10 is used to coat the current collector 5 , that is, to apply the cathode / anode slurry to the current collector. As shown in FIG1 , the coating system 10 may include a backing roller 11 , a coating extrusion head 12 , and a guide roller 13 .

[0066] The oven system 20 is used to dry the current collector 5 entering the oven.

[0067] FIG2 is a schematic diagram of an oven system according to one or more embodiments. As shown in FIG2 , the oven system includes an oven body 1 , a traction device 2 , a fixing component 3 and a controller 4 .

[0068] As shown in FIG1 , a drying chamber is provided in the box body 1 , and a current collecting inlet 14 and a current collecting outlet 15 communicating with the drying chamber are provided on the box body 1 .

[0069] As shown in FIG1 , the traction device 2 passes through the drying chamber.

[0070] As shown in FIG. 1 and FIG. 2 , the fixing component 3 is connected to the traction device 2 .

[0071] Figure 3 is a schematic diagram of a current collector being broken according to one or more embodiments. Figure 4 is a schematic diagram of a broken current collector being pushed to both ends of an oven according to one or more embodiments. Figure 5 is a schematic diagram of a broken current collector being automatically passed through an oven according to one or more embodiments. Figure 6 is a schematic diagram of a broken current collector after automatically passing through an oven according to one or more embodiments. Figures 3 to 6 are top views of the oven system.

[0072] In some embodiments, as shown in FIG5 , the fixing member 3 is a pull rod or a cross bar, and the fixing member 3 is arranged perpendicular to the traction member 21 and parallel to the flow direction 6 of the current collector. The specific composition and arrangement direction of the fixing member 3 are defined, so that the traction member 21 can drive the cross bar, which in turn drives the broken belt, automatically allowing the current collector to pass through the oven.

[0073] As shown in Figures 1 to 6, the controller 4 is configured to control the coating system to push the first broken segment of the current collector to the first side outside the box, and pull the second broken segment of the current collector to the second side outside the box (as shown in Figure 4) when the current collector is broken (as shown in Figure 3), wherein the second side is the side in the opposite direction of the first side, and the first side or the second side is the inlet side of the current collector; control the traction device 2 and the fixing component 3 to pull the first broken segment fixed to the fixing component 3 through the drying chamber (as shown in Figures 5 and 6), wherein the current collector passing direction 16 is the direction of the first broken segment from the first side to the second side.

[0074] In some embodiments, the first side of FIG. 3 to FIG. 6 may be the side of the current collector inlet 14 as shown in FIG. 1 , and the second side may be the side of the current collector outlet 15 as shown in FIG. 1 .

[0075] In other embodiments, the second side of FIG. 3 to FIG. 6 may be the side of the current collector inlet 14 as shown in FIG. 1 , and the first side may be the side of the current collector outlet 15 as shown in FIG. 1 .

[0076] In the technical solution of this embodiment, a method for automatically threading the current collector after it breaks in the oven is provided. This embodiment provides a traction device that passes through the drying chamber, and a fixed component connected to the traction device, to control the traction device and the fixed component, and to pull the first broken segment fixed to the fixed component through the drying chamber. A traction device is used to pass through the oven, and the fixed component is connected to the traction device. The broken current collector is pulled through the oven by the movement of the fixed component, thereby replacing the process of maintenance personnel opening the oven door and manually pulling it through the oven. In this way, there is no direct contact between personnel and the oven system, which greatly reduces the chances of potential risks such as high temperature injury, NMP injury, and structural injury to personnel. On the other hand, because there is no need for personnel to contact the oven system, threading can be performed directly 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, and greatly reducing heat waste and saving energy consumption.

[0077] FIG7 is a schematic diagram of an oven system according to one or more embodiments. Compared with the embodiment of FIG2 , in the embodiment of FIG7 , the traction device may include a traction component 21 and a driving component 22 .

[0078] Figure 8 is a schematic diagram of a drying oven system according to one or more embodiments. Figure 8 is a front view of the drying oven system according to the embodiment of Figure 5 . As shown in Figures 1 and 8 , a traction member 21 passes through the drying chamber. Within the drying chamber, the traction member 21 is parallel to the current collector flow direction 6 and is connected to the fixing member 3 .

[0079] As shown in FIG7 , the driving component 22 is configured to drive the traction component 21 and the fixing component 3 to move according to control instructions from the controller 4, thereby pulling the first broken segment 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 pulling the broken current collector through the drying oven, enabling rapid resumption of production and significantly reducing potential harm to maintenance personnel.

[0080] In some embodiments, the traction member 21 is a cable or a steel cable. In this embodiment, the driving member 22 can drive the cable, the cable drives the cross bar, the cross bar drives the broken belt, and the broken belt is pulled through the oven to quickly resume production.

[0081] Figure 9 is a schematic diagram of an oven system according to one or more embodiments. As shown in Figures 5, 9, and 10, there is at least one pulling member 21. As shown in Figure 9, when there is only one pulling member 21, it is connected to the fixing member 3 at a midpoint along the length of the fixing member 3. In this embodiment, a single pulling member 21 is connected to the fixing member 3 at a midpoint along the length of the fixing member 3. This allows the fixing member 3 and the broken current collector to be pulled together using only one pulling member 21.

[0082] In some embodiments, as shown in FIG5 , when there are two traction members 21, the two traction members 21 are parallel to each other and are connected to the fixing member 3 at both sides of the length direction of the fixing member 3. In this embodiment, two traction members 21 are connected to the fixing member 3 at both sides of the length direction of the fixing member 3, respectively. Thus, the fixing member 3 can be pulled together by the two traction members 21 at both sides of the length direction of the fixing member 3, thereby achieving more stable driving of the fixing member 3 and the broken current collector.

[0083] FIG10 is a schematic diagram of an oven system according to one or more embodiments. As shown in FIG10 , the number of traction members 21 is three. When the number of traction members 21 is at least three, the at least three traction members 21 are parallel to each other, and the connection positions of two traction members 21 with the fixed member 3 are on both sides of the length direction of the fixed member 3, and the connection positions of the other traction members 21 with the fixed member 3 are evenly arranged between the two sides. In this embodiment, at least three traction members 21 are evenly arranged at the connection positions in the length direction of the fixed member 3, so that the fixed member 3 can be pulled together by the at least three traction members 21 in the length direction of the fixed member 3, thereby achieving a more stable driving of the fixed member 3 and the broken current collector.

[0084] In some embodiments, as shown in FIG. 1 , FIG. 5 , and FIG. 8 to FIG. 10 , the oven system may further include a label 7 and a first label sensor 8 .

[0085] As shown in FIG. 5 and FIG. 8 to FIG. 10 , the label 7 is provided on the traction member 21 at a position connected to the fixing member 3 .

[0086] As shown in Figures 1 and 8, a first tag sensor 8 is disposed on the second side. The first tag sensor 8 is configured to detect the tag 7 on the traction member 21. The controller 4 is further configured to remove the first broken segment from the fixing member 3 and perform a current collector connection between the first and second broken segments when the first tag sensor 8 detects the tag 7 on the traction member 21. In this embodiment, the tag sensor senses the position of the fixing member 3 to position the crossbar fixing member 3, facilitating the removal of the broken current collector from the fixing member 3 at the tail end of the machine and the current collector connection between the first and second broken segments. Thus, by sensing the tag 7 via the tag sensor, it is possible to accurately determine that the broken belt has moved outside the oven, allowing the current collector connection between the first and second broken segments to be performed.

[0087] In some embodiments, the controller 4 may be further configured to, after the first and second broken segments are connected to the current collector, control the driving component 22 to drive the traction component 21 to move, pull the fixing component 3 back to its initial position on the first side, and stop the movement of the traction component 21. This embodiment automatically moves the fixing component 3 back to its original position to prepare for the next threading (when the broken current collector passes through the oven).

[0088] In some embodiments, as shown in FIG. 1 , FIG. 5 , and FIG. 8 to FIG. 10 , the oven system may further include a second tag sensor 9 .

[0089] A second tag sensor 9 is disposed on the first side of the box, wherein the second tag sensor 9 is configured to detect the tag 7 on the traction member 21. The controller 4 is further configured to determine that the fixing member 3 has returned to its initial position on the first side and to stop moving the traction member 21 if the second tag sensor 9 detects the tag 7 on the traction member 21. This embodiment uses the tag sensor to sense the position of the fixing member 3, enabling more accurate automatic positioning of the fixing member 3, making it easier to secure a broken tape to the fixing member 3 during the next threading.

[0090] 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 color mark sensor senses the position of the fixing component 3, enabling automatic positioning of the fixing component 3 and facilitating the fixing of a broken tape to the fixing component 3. The color mark sensor controls the fixing component 3 to remain at the splicing position before entering the oven and at the splicing position after exiting the oven.

[0091] In some embodiments, the controller 4 may be further configured to control the driving component 22 to drive the pulling component 21 and the fixing component 3 to move, thereby pulling the first broken segment from the first side to the second side through the drying chamber at a constant speed. This embodiment improves the success rate and efficiency of the threading by controlling the threading speed to be constant.

[0092] In some embodiments, as shown in Figures 1 and 8, the traction component 21 has a closed shape, wherein the traction component 21 includes a portion 211 passing through the drying chamber and a portion 212 outside the box, and the portion 211 passing through the drying chamber and the portion 212 outside the box constitute a closed shape.

[0093] In some embodiments, as shown in Figures 1, 7, and 8, the traction device may further include guide wheels 23, wherein each traction member 21 passes around at least two guide wheels 23. The closed traction member 21 rotates around the at least two guide wheels 23, thereby facilitating the traction member 21 to pull the fixing member 3 and the broken current collector.

[0094] In some embodiments, the guide wheels in FIG7 may include the first guide wheel 231, the second guide wheel 232, the third guide wheel 233, and the fourth guide wheel 234 in the embodiments of FIG1 and FIG8. As shown in FIG1 and FIG8, each traction component 21 passes through four guide wheels 23 to form a rectangle. The traction component 21 on the upper side of the rectangle passes through the drying chamber, the traction component 21 on the lower side of the rectangle is located on the lower side outside the drying chamber, the traction component 21 on the left side of the rectangle is located on the second side outside the drying chamber, and the traction component 21 on the right side of the rectangle is located on the first side outside the drying chamber. The four guide wheels 23 are respectively located at the four vertices of the rectangle. Starting from the guide wheel 23 on the lower side of the second side, 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 in a clockwise direction. The first tag sensor 8 is provided on the second guide wheel 232, and the second tag sensor 9 is provided on the third guide wheel 233. This embodiment defines the positions of four guide wheels 23 and label sensors, and uses the rotation of the closed rectangular traction component 21 to automatically achieve traction of the fixing component 3 and the broken current collector 5, and can easily pass the broken current collector through the oven.

[0095] In some embodiments, the drive component may include a drive wheel and a motor.

[0096] In some embodiments, the driving wheel may be a rubber roller.

[0097] In some embodiments, the pulling member may be a cable or a steel cable.

[0098] In some embodiments, the fixing member may be implemented as a crossbar.

[0099] This embodiment uses two parallel traction members that pass through the oven mechanism and bypass four guide wheels, forming two parallel closed loops. A drive wheel (rubber roller) presses against the traction members, which are driven by a motor. The drive wheel propels the traction members forward through friction, and a fixed member is positioned between the two traction members. Outside the oven, the broken belt is secured to the fixed member, which then pulls the broken belt through the oven and reconnects it outside. This allows for rapid resumption of production and significantly reduces potential injuries to maintenance personnel.

[0100] FIG11 is a schematic diagram of a driving component according to one or more embodiments. As shown in FIG1 , FIG8 and FIG11 , the driving component 22 of the embodiment of FIG7 may include: a tension sensor 221 , a driving wheel 222 and a variable frequency motor 223 .

[0101] As shown in FIG. 8 , the tension sensor 221 is provided on any one of the 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 .

[0102] The driving wheels 222 , as shown in FIG1 and FIG8 , are each disposed on the outside of a traction component 21 and are configured to drive the traction component 21 to rotate.

[0103] The variable frequency motor 223 is configured to drive the driving wheel to rotate, thereby driving the traction component 21 to rotate.

[0104] The controller 4 can also be configured to compare the current measurement value of the tension sensor with the target tension value; when the current measurement value of the tension sensor is greater than the target tension value, reduce the input control value of the variable frequency motor; when the current measurement value of the tension sensor is less than the target tension value, increase the input control value of the variable frequency motor, so that the first breaking segment passes through the drying chamber at a uniform speed from the first side to the second side.

[0105] In some embodiments, as shown in Figure 11, the controller 4 may include a comparison module and a PID controller module, wherein the comparison module may be configured to compare the measurement value of the current tension sensor with the target tension value; the PID controller module may be configured to reduce the input control value of the variable frequency motor when the measurement value of the current tension sensor is greater than the target tension value, and increase the input control value of the variable frequency motor when the measurement value of the current tension sensor is less than the target tension value, so that the first breaking segment passes through the drying chamber at a uniform speed from the first side to the second side.

[0106] This embodiment drives the traction component 21 through a tension sensor, a variable frequency motor, a drive wheel and a PID (Proportional-Integral-Derivative) control method. Specifically, the tension sensor detects the control of the traction force during the traction process, controls the uniform movement of the current collector, and greatly reduces the risk of breaking the current collector again. At the same time, it can also automatically adjust the traction speed through closed-loop control of tension and traction speed to improve the threading efficiency.

[0107] In some embodiments, as shown in Figures 1 and 8, a tension sensor is provided on the guide wheel 234 closest to the driving wheel among the at least two guide wheels around which each traction member 21 passes. By providing the tension sensor on the guide wheel closest to the driving wheel, speed control can be achieved more accurately.

[0108] FIG12 is a schematic diagram of a driving component according to one or more embodiments. As shown in FIG1 and FIG12 , the driving component 22 may include a driving wheel 222 and a servo motor 224 .

[0109] The driving wheels 222 , wherein each driving wheel is respectively disposed on the outside of a traction component 21 , are configured to drive the traction component 21 to rotate.

[0110] The servo motor 224 is configured to drive the driving wheel to rotate, thereby driving the traction component 21 to rotate.

[0111] The controller 4 can also be configured to obtain the current current of the servo motor and determine the actual torque value of the servo motor; compare the actual torque value with the required torque; when the actual torque value is greater than the required torque, reduce the current current of the servo motor; when the actual torque value is less than the required torque, increase the current current of the servo motor, so that the first breaking segment passes through the drying chamber at a uniform speed from the first side to the second side.

[0112] In some embodiments, as shown in Figure 12, the controller 4 may include a comparison module and a PID controller module, wherein 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 fracture segment passes through the drying chamber at a uniform speed from the first side to the second side.

[0113] This embodiment drives the traction component 21 through a servo motor, drive wheel, and PID control method. The drive wheel is driven by a servo motor and pulls the current collector through the drying chamber at a constant speed. The pulling force is controlled by servo torque feedback. This embodiment can control the current collector's uniform movement, significantly reducing the risk of further breakage, automatically adjusting the traction speed, and improving threading efficiency. Furthermore, compared to control methods that require a tension sensor, variable frequency motor, drive wheel, and PID, this method reduces the process and cost of setting up a tension sensor.

[0114] FIG13 is a schematic diagram of a driving component according to one or more embodiments. As shown in FIG13 , the driving component 22 may include a first hoisting mechanism 225 and a second hoisting mechanism 226 .

[0115] In some embodiments, the traction component 21 is in a non-closed shape, wherein the traction component 21 includes a portion passing through the drying chamber; the driving component 22 includes: a first hoisting mechanism arranged on the first side; and a second hoisting mechanism arranged on the second side, wherein each traction component 21 is connected to a first hoisting mechanism and a second hoisting mechanism.

[0116] The controller 4 can also be configured to control the second hoisting mechanism to retract the traction component 21 and control the first hoisting mechanism to release the traction component 21 after the first broken segment is fixed to the fixed component 3, so as to pull the first broken segment through the drying chamber through the traction component 21 and the fixed component 3. Each traction component 21 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. In this embodiment, by retracting and releasing the traction component 21 through the hoisting mechanism, a non-closed traction component 21 can be used to achieve traction of the fixed component 3 and the broken current collector, thereby reducing the length of the traction component 21 and reducing the space occupied outside the oven, thereby achieving the automatic migration of the broken current collector through the oven.

[0117] In some embodiments, the traction member 21 is a cable or a steel cable. In this embodiment, the driving member 22 drives the cable, the cable drives the crossbar, the crossbar drives the broken belt, and the broken belt is pulled through the oven to quickly resume production.

[0118] In this embodiment, the crossbar pulls the current collector through the oven under the working temperature environment to achieve rapid tape connection.

[0119] In this embodiment, the color mark sensor is used to control the crossbar to stay at the splicing position before the tape enters the oven and the splicing position when the tape exits the oven.

[0120] This embodiment uses a tension sensor to close the loop to control the threading speed, thereby improving the threading success rate and efficiency.

[0121] This embodiment uses two sets of cables threaded through the oven, with a crossbar fixed between them. The crossbar's movement allows the broken ribbon to be pulled through the oven, eliminating the need for maintenance personnel to open the oven door and manually pull the ribbon through the oven. This embodiment significantly reduces direct contact between personnel and the oven system, thereby significantly reducing potential risks of injury from high temperatures, NMP, and mechanical damage. Furthermore, because personnel do not need to contact the oven system, the ribbon can be threaded directly at operating temperature, eliminating the need to wait for the oven to cool down and reach operating temperature. This significantly reduces downtime, heat waste, and energy consumption.

[0122] Figure 14 is a schematic diagram of a method for controlling current collector penetration in 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 current collector penetration in an oven system is described in detail below. The embodiment in Figure 14 may include at least one of steps 100 and 200.

[0123] Step 100, in the case that the current collector is broken, the controller controls the coating system to push the first broken segment of the current collector to the first side outside the box, and pull the second broken segment of the current collector to the second side outside the box, wherein the oven system includes a controller and a box body, a drying chamber is provided in the box body, and the box body has a current collector inlet and a current collector outlet connected to the drying chamber, the second side is the side in the opposite direction of the first side, and the first side or the second side is the current collector inlet side.

[0124] In some embodiments, step 100 may include step 110 and step 120 .

[0125] Step 110, when the belt breaks in the oven, the tension sensor at the coating equipment exiting the oven detects that the tension is 0, and the touch screen pops up an alarm indicating that the belt is broken in the oven (as shown in Figure 3). Based on user input or system braking, it is determined whether to start the automatic belt splicing mode.

[0126] Step 120, confirm to start the automatic tape splicing mode, operate the coating system to rotate forward, and pull the front part of the broken tape (the first broken section) out of the oven; operate the coating system to rotate reversely, and push the rear part of the broken tape (the second broken section) out of the oven, as shown in Figure 4.

[0127] In step 200, the controller controls the traction device and the fixing component 3 to pull the first broken segment fixed to the fixing component 3 through the drying chamber, wherein the drying 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.

[0128] In some embodiments, step 200 may include: a controller controlling a driving component 22 to drive a traction component 21 and a fixing component 3 to move, thereby pulling the first broken segment through the drying chamber, wherein the traction device includes a traction component 21 and a driving component 22, the traction component 21 passing through the drying chamber, the traction component 21 being parallel to the flow direction 6 of the current collector within the drying chamber, and the traction component 21 being connected to the fixing component 3. The driving component 22 can drive the traction component 21 and the fixing component 3 to move, thereby automatically pulling the broken current collector through the oven, thereby quickly resuming production and significantly reducing potential harm to maintenance personnel.

[0129] In the technical solution of this embodiment, a traction device passing through the drying chamber and a fixed component 3 connected to the traction device are provided, and the traction device and the fixed component 3 are controlled to pull the first broken segment fixed to the fixed component 3 through the drying chamber. The traction device is used to pass through the oven, and the fixed component 3 is connected to the traction device. Through the movement of the fixed component 3, the broken current collector is pulled through the oven, thereby replacing the process of maintenance personnel opening the oven door and manually pulling it through the oven. In this way, there is no direct contact between personnel and the oven system, which greatly reduces the probability of potential risks such as high temperature injury, NMP injury and structural injury to personnel. On the other hand, because there is no need for personnel to contact the oven system, the belt can be threaded directly 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, and greatly reducing heat waste and saving energy consumption.

[0130] In some embodiments, step 200 may include: the controller controls the driving component 22 to drive the pulling component 21 and the fixing component 3 to move, thereby pulling the first broken segment from the first side to the second side through the drying chamber at a constant speed. This embodiment improves the success rate and efficiency of the threading by controlling the threading speed to be constant.

[0131] In some embodiments, as shown in FIG. 11 , step 200 may include at least one of steps 210 to 240 .

[0132] In step 210, the controller drives the driving wheel to rotate through the variable frequency motor, thereby driving the traction component 21 to rotate, wherein 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. The part passing through the drying chamber and the part outside the box form a closed shape, and each driving wheel is respectively arranged on the outside of a traction component 21.

[0133] In step 220 , the controller detects the tension applied to the guide wheel 23 through a tension sensor, wherein each traction component 21 passes around at least two guide wheels 23 , and the tension sensor is provided on any one of the at least two guide wheels 23 passed around by each traction component 21 .

[0134] In step 230 , the controller compares the current measurement value of the tension sensor with the target tension value.

[0135] In some embodiments, step 230 may include: obtaining an initial threading speed input by a user; and calculating a target tension value according to the initial threading speed.

[0136] In some embodiments, the actual value of the threading 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 speed. Therefore, this embodiment converts the threading speed into a frequency output.

[0137] For example: to convert the linear speed into frequency output, the conversion process may include: according to the inverter and motor parameters, the inverter output value of 10000 corresponds to the maximum motor speed of 1460r / min; set the PLC control division to 1000, that is, 1000 corresponds to the inverter output value 1, so the PLC output 10000*1000 corresponds to the motor 1460r / min; the motor drives the rubber roller (driving wheel) to rotate through the gear set, and 1460r / min is converted to the rubber roller linear speed as: 1460*2*r*Π / K, K is the gear set reduction ratio; In summary, the PLC output frequency When the rate value is 10000*1000, the corresponding roller linear speed is: 1460*2*r*Π / K; according to the geometric relationship between the PLC output frequency value and the linear speed, VFD_SV / 10000*1000=HMI_SV / (1460*2*r*Π / K); it can be known that the corresponding PLC frequency output at any speed is: VFD_SV=10000*1000*HMI_SV*K / (1460*2*r*Π); the frequency is fine-tuned through the system PID function block (as shown in Figure 11) to obtain the final output frequency: VFD_OUT.

[0138] Step 240, when the current measurement value of the tension sensor is greater than the target tension value, the controller reduces the input control value of the variable frequency motor; when the current measurement value of the 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 breaking segment passes through the drying chamber at a uniform speed from the first side to the second side.

[0139] This embodiment drives the traction component 21 through a tension sensor, a variable frequency motor, a drive wheel and a PID control method. 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 at a uniform speed, which greatly reduces the risk of the current collector being broken again. At the same time, the traction speed can be automatically adjusted through closed-loop control of the tension and traction speed to improve the threading efficiency.

[0140] In some embodiments, as shown in FIG. 12 , step 200 may include at least one of steps 250 to 280 .

[0141] In step 250, the controller drives the driving wheel to rotate through the servo motor, thereby driving the traction component 21 to rotate, wherein 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. The part passing through the drying chamber and the part outside the box form a closed shape, and each driving wheel is respectively arranged on the outside of a traction component 21, and each traction component 21 passes around at least two guide wheels 23.

[0142] In step 260 , the controller obtains the current of the servo motor and determines the actual torque value of the servo motor.

[0143] In step 270 , the controller compares the actual torque value with the desired torque.

[0144] Step 280, when the actual torque value is greater than the required torque, the controller reduces the current current of the servo motor; and 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 segment passes through the drying chamber at a uniform speed from the first side to the second side.

[0145] In some embodiments, as shown in Figure 1 , the traction component can be a cable, the fixing component 3 can be a crossbar, the label 7 can be a color code, and the color code is affixed to the cable where it connects to the crossbar. The second label sensor 9 and the first label sensor 8 can be color code sensors. In this embodiment, the servo motor drives the cable at a constant speed, driving the pull rod through the oven. The servo motor operates in torque mode. When the torque reaches a set protection value, the servo stops operating, and manual troubleshooting is performed to determine whether to continue threading or rethread the belt.

[0146] In some embodiments, steps 250 to 280 may include: setting an initial speed and a protective torque; starting threading (current collector threading); judging whether the shaft state is normal; when the shaft state is normal, starting the unwinding shaft; starting the threading servo motor after a predetermined time interval; judging whether the servo torque is greater than the protective torque; when the servo torque is greater than the protective torque, judging that threading has failed; whether the first label sensor senses a label; when the first label sensor senses a label, judging that threading is successful; when the first label sensor cannot sense a label, judging that threading has failed; when threading is successful or fails, stopping the unwinding shaft and the threading servo motor, and threading ends.

[0147] This embodiment drives the traction component 21 through a servo motor, drive wheel, and PID control method. The drive wheel is driven by a servo motor and pulls the current collector through the drying chamber at a constant speed. The pulling force is controlled by servo torque feedback. This embodiment can control the current collector's uniform movement, significantly reducing the risk of further breakage, automatically adjusting the traction speed, and improving threading efficiency. Furthermore, compared to control methods that require a tension sensor, variable frequency motor, drive wheel, and PID, this method reduces the process and cost of setting up a tension sensor.

[0148] In some embodiments, step 200 may include: as shown in FIG11 , after the first broken segment is fixed to the fixing member 3, the controller controls the second hoisting mechanism to retract the traction member 21 and controls the first hoisting mechanism to release the traction member 21, and the first broken segment is pulled through the drying chamber by the traction member 21 and the fixing member 3, wherein the traction member 21 is in a non-closed shape, wherein the traction member 21 includes a portion that passes through the drying chamber, and each traction member 21 is connected to a first hoisting mechanism and a second hoisting mechanism, the first hoisting mechanism being arranged on the first side, and the second hoisting mechanism being 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 achieve traction of the fixing member 3 and the broken current collector, thereby achieving the automatic migration of the broken current collector through the oven while reducing the length of the traction member 21 and the space occupied outside the oven.

[0149] Figure 15 is a schematic diagram of a method for controlling current collector flow in 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 embodiment of Figure 15 may include at least one of steps 100 and 200, and at least one of steps 300 through 500.

[0150] In step 300 , the controller detects the label 7 on the traction component 21 through the first label sensor 8 , wherein the label 7 is provided at the connection position between each traction component 21 and the fixing component 3 , and the first label sensor 8 is provided on the second side.

[0151] In step 400, when first tag sensor 8 detects tag 7 on traction member 21, the controller instructs the first broken segment to be removed from fixing member 3 and the first and second broken segments to be connected by the current collector. By sensing tag 7 with the tag sensor, it is possible to accurately determine that the broken tape has moved outside the oven, allowing the first and second broken segments to be connected by the current collector.

[0152] Step 500 , after the first broken segment and the second broken segment are connected by current collector, the controller controls the driving component 22 to drive the traction component 21 to move, pulls the fixing component 3 back to the initial position of the first side, and stops the movement of the traction component 21 .

[0153] In some embodiments, in step 500, the step of returning the fixing member 3 to its initial position on the first side may include: the controller detecting the label 7 on the traction member 21 via the second label sensor 9, wherein the second label sensor 9 is disposed on the first side; and when the second label sensor 9 detects the label 7 on the traction member 21, the controller determines that the fixing member 3 has returned to its initial position on the first side and stops moving the traction member 21. This embodiment automatically moves the fixing member 3 back to its original position to prepare for the next time a broken current collector passes through the oven.

[0154] In some embodiments, as shown in Figures 1 and 8, the traction component can be a cable, the fixing component 3 can be a crossbar, the label 7 can be a color code, and the color code is affixed to the cable at the location where it connects to the crossbar. The second label sensor 9 and the first label sensor 8 can be color code sensors. The first side can be the machine head (collector inlet), and the second side can be the machine tail (collector outlet). Steps 200 to 500 may include: at the machine head, securing the rear section of the broken tape to the crossbar, and then starting the drive wheel to rotate forward. The crossbar drives the collector through the oven. During the movement of the crossbar, the tension value fed back by the tension sensor automatically adjusts the travel speed. When the color code sensor at the tail of the machine senses the color code, the drive wheel stops rotating forward; at the tail of the machine, the broken tape is removed from the crossbar and bonded to the front end of the broken tape. The drive wheel is then reversed, and the crossbar returns to its initial position at the machine head. When the color code sensor at the machine head senses the color code, the drive wheel stops rotating, and automatic tape threading is completed.
