Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying equipment technology, specifically to a correction drying oven and drying oven system. Background Technology
[0002] As demand in the lithium battery industry increases, the demand for corresponding production equipment is also gradually increasing. However, the production speed of production equipment is generally directly proportional to the length of the oven. Therefore, the length of ovens on the market is constantly increasing, reaching 80 meters or even longer. With such a large span, the stability of the substrate is not easy to guarantee. At this time, relevant auxiliary equipment is needed to ensure the stability of the production process. Correction is one of the commonly used methods.
[0003] In existing lithium battery equipment, the alignment device is mostly located at both ends of the oven. Its main purpose is to prevent slight shifts in the substrate during movement and to correct them promptly, ensuring the quality of the coated product. However, when the coating line length reaches tens or even hundreds of meters, the substrate may shift due to factors such as fan vibration, unstable airflow and pressure, and uneven temperature. After moving for tens of meters, the substrate's shift upon exiting the oven can be relatively large due to these unstable factors. In such cases, alignment via the machine head and tail alone is difficult, affecting product quality and production schedule. Furthermore, alignment via the machine head and tail requires a support frame at the oven location, which is unsightly and exposes the coated substrate to air within the oven section, impacting coating quality. Utility Model Content
[0004] In view of this, the present invention provides a correction oven and oven system to solve the problem that it is difficult to correct the substrate at the head and tail of the machine, and that the substrate will come into contact with air, which will affect the coating quality.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] In a first aspect, this utility model provides a web-correcting drying oven, comprising:
[0007] The box body has a substrate inlet at one end and a substrate outlet at the other end, and the box body is set between two adjacent substrate drying ovens;
[0008] A correction mechanism is provided inside the chamber and is used to correct the deviation of the substrate output from the substrate drying oven.
[0009] The beneficial effects of the above-mentioned corrective drying oven are as follows:
[0010] This invention adds a correction oven between two adjacent substrate drying ovens. The correction mechanism, built into the oven's interior, adjusts the substrate's offset position more promptly, avoiding significant deviations that can occur with correction only at the head and tail ends of the machine. This prevents substrate misalignment and wrinkling within the drying oven, improving substrate utilization and ensuring coating quality. Furthermore, this invention performs real-time correction of the middle section of the substrate during transport, reducing downtime for adjustments due to substrate misalignment, improving production line continuity and stability, and thus enhancing overall production efficiency. Integrating the correction mechanism into the oven and placing it between adjacent drying ovens eliminates the need for external supports, resulting in a more compact and aesthetically pleasing structure and saving space.
[0011] Furthermore, the correction oven of this utility model is assembled between two adjacent substrate oven sections, ensuring the overall sealing of the substrate oven. During the correction process, the substrate will not come into contact with air, thus preventing the substrate from contacting the outside air and affecting the coating quality.
[0012] The technical solution is further optimized, and the correction mechanism includes:
[0013] A correction roller assembly is disposed inside the housing and is used to support and convey the substrate.
[0014] A drive assembly is used to drive the alignment roller assembly to rotate in a horizontal plane, thereby correcting the substrate on the alignment roller assembly.
[0015] The beneficial effects of the above technical solution are: the driving component can precisely drive the correction roller component to rotate in the horizontal plane, thereby achieving fine adjustment of the substrate position and ensuring that the substrate always stays on the ideal path throughout the entire transmission process.
[0016] The technical solution is further optimized by including at least one correction roller assembly, with each correction roller rotatably mounted on two correction roller positioning frames, and the substrate supported on the correction roller.
[0017] The beneficial effects of the above technical solution are: the substrate can be directly transferred through the correction roller, the substrate with top surface coated with slurry can be transferred, and thus the substrate with single-sided coating of slurry can be transferred.
[0018] The technical solution is further optimized by making the correction roller a hollow air-floating roller, and the inner cavity of the air-floating roller is connected to the ventilation mechanism.
[0019] The air flotation rollers are provided in three parts, namely a first air flotation roller, a second air flotation roller and a third air flotation roller; the substrate is wrapped around the top of the first air flotation roller, around the bottom of the second air flotation roller, and then wrapped around the top of the third air flotation roller; the first air flotation roller, the second air flotation roller and the third air flotation roller are respectively provided with a plurality of air flow holes at the positions in contact with the substrate, and the air flow holes are connected to the inner cavity of the air flotation roller.
[0020] The beneficial effects of the above technical solution are as follows: after the substrate is wrapped around three air flotation rollers, the substrate can be completely suspended, which can transfer the substrate with double-sided coating slurry, thereby realizing the drying of the substrate with double-sided coating slurry.
[0021] The technical solution is further optimized so that the heights of the first and third air flotation rollers are the same, and the height of the second air flotation roller is lower than that of the first and third air flotation rollers.
[0022] The beneficial effects of the above technical solution are as follows: Since the height of the second air flotation roller is lower than that of the first and third air flotation rollers, the two adjacent air flotation rollers are staggered in the height direction. When the substrate passes around these air flotation rollers, it forms a natural undulation, which effectively avoids the slurry from contacting the adjacent air flotation rollers when the substrate floats up, thereby reducing the risk of slurry adhesion.
[0023] The technical solution is further optimized by making the airflow holes on the first air flotation roller have an opening range of more than 90°, the airflow holes on the second air flotation roller have an opening range of more than 180°, and the airflow holes on the third air flotation roller have an opening range of more than 90°. This allows the gas blown out of the airflow holes on the first air flotation roller to form convection with the gas blown out of the airflow holes on the second air flotation roller, and also allows the gas blown out of the airflow holes on the second air flotation roller to form convection with the gas blown out of the airflow holes on the third air flotation roller. This ensures that the airflow on both sides of the substrate is consistent, guaranteeing that the substrate is always in the middle position between the first and second air flotation rollers, and also in the middle position between the second and third air flotation rollers.
[0024] To further optimize the technical solution, the ventilation mechanism includes a duct and a fan. The duct is installed on the housing and communicates with the inner cavity of the air flotation roller. The fan is installed at the end of the duct.
[0025] And / or, the first air flotation roller, the second air flotation roller and the third air flotation roller are each uniformly arranged with a plurality of airflow holes;
[0026] And / or, the second air flotation roller is height-adjusted via a lifting structure.
[0027] To further optimize the technical solution, the correction mechanism also includes a correction frame, which is divided into an upper frame and a lower frame. The correction roller assembly is mounted on the upper frame, the driving end of the driving assembly is hinged to the upper frame, and the fixed end of the driving assembly is hinged to the lower frame.
[0028] A slide rail is provided at the corner of the upper frame, and a connecting rod is connected to the drive end of the drive assembly. The end of the connecting rod is hinged to the upper frame. Rollers are provided on the lower frame.
[0029] The drive assembly is a reciprocating drive assembly. When the drive assembly drives the connecting rod to reciprocate, the roller moves within the slide rail, thereby causing the upper frame to rotate relative to the lower frame, which in turn drives the correction roller assembly to rotate.
[0030] To further optimize the technical solution, the substrate inlet and / or substrate outlet of the housing are provided with a correction sensor bracket, and a correction sensor is provided on the correction sensor bracket. The correction sensor is used to detect the offset of the substrate and feed the offset back to the control system so that the control system controls the correction mechanism to correct the substrate.
[0031] To further optimize the technical solution, the correction sensor bracket is connected to a correction sensor moving structure, which is used to adjust the position of the correction sensor bracket and the correction sensor.
[0032] The beneficial effects of the above technical solution are as follows: by adjusting the position of the correction sensor through the correction sensor moving structure, the correction sensor is aligned so that the correction sensor can be used for substrates of different sizes and types.
[0033] To further optimize the technical solution, the correction sensor is provided in at least one pair, with the two correction sensors in each pair located on both sides inside the housing.
[0034] The beneficial effects of the above technical solution are as follows: the pair arrangement of the correction sensors can detect the position status of the two sides of the substrate respectively, ensuring that the offset of the substrate in the entire width direction can be accurately captured.
[0035] Secondly, this utility model provides an oven system, comprising:
[0036] A substrate drying oven, wherein the interior of the substrate drying oven is provided with a substrate conveying channel;
[0037] At least one of the aforementioned straightening ovens is disposed between two adjacent substrate ovens along the substrate conveying channel direction.
[0038] The beneficial effects of the above technical solution are: one or more correction ovens can be set between two adjacent substrate ovens, which can not only ensure the sealing during correction, but also enhance the correction effect. Attached Figure Description

[0050] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0051] In existing lithium battery equipment, the alignment device is mostly located at both ends of the oven. Its main purpose is to prevent slight shifts in the substrate during movement and to correct them promptly, ensuring the quality of the coated product. However, when the coating line length reaches tens or even hundreds of meters, the substrate may shift due to factors such as fan vibration, unstable airflow and pressure, and uneven temperature. After moving for tens of meters, the substrate's shift upon exiting the oven can be relatively large due to these unstable factors. In such cases, alignment via the machine head and tail alone is difficult, affecting product quality and production schedule. Furthermore, alignment via the machine head and tail requires a support frame at the oven location, which is unsightly and exposes the coated substrate to air within the oven section, impacting coating quality.
[0052] In summary, existing ovens with long spans can cause substrates to shift when exiting the oven during production, which can easily lead to wrinkling of the substrate.
[0053] To address this issue, this invention provides a correction oven to solve the problem of substrate shifting during the oven's movement in the production process. It incorporates air flotation correction to adjust the substrate in a timely manner, ensuring the substrate maintains its quality during production and reducing substrate waste.
[0054] The following is combined Figures 1 to 8 The first aspect of this utility model, the correction oven, and the second aspect of this utility model, the drying oven system, are described in detail.
[0055] According to an embodiment of the present invention, in a first aspect, a correction oven is provided, comprising a chamber body 1 and a correction mechanism. One end of the chamber body 1 is a substrate inlet, and the other end of the chamber body 1 is a substrate outlet. The chamber body 1 is disposed between two adjacent substrate drying chambers. The correction mechanism is disposed inside the chamber body 1 and is used to correct the deviation of the substrate 8 output from the substrate drying chamber.
[0056] This embodiment adds a correction oven between two adjacent substrate drying ovens. The correction mechanism, built into the oven's interior, adjusts the substrate 8's offset position more promptly, avoiding significant deviations that might occur with correction only at the head and tail ends of the machine. This prevents substrate misalignment and wrinkling within the drying oven, improving substrate utilization and ensuring coating quality. This embodiment also performs real-time correction of the substrate's mid-section during transport, reducing downtime for adjustments due to substrate misalignment, improving production line continuity and stability, and thus enhancing overall production efficiency. Integrating the correction mechanism into the oven and placing it between adjacent substrate drying ovens eliminates the need for external supports, resulting in a more compact and aesthetically pleasing structure and saving space.
[0057] Furthermore, in this embodiment, the correction oven is assembled between two adjacent substrate oven sections, ensuring the overall sealing of the substrate oven. During the correction process, the substrate 8 will not come into contact with air, thus preventing the substrate 8 from coming into contact with the outside air and affecting the coating quality.
[0058] In some embodiments, the correction mechanism includes a correction roller assembly 2 and a drive assembly 4. The correction roller assembly 2 is disposed inside the housing 1 and is used to support and convey the substrate. The drive assembly 4 is used to drive the correction roller assembly 2 to rotate in a horizontal plane, thereby correcting the substrate on the correction roller assembly 2. In this embodiment, the drive assembly 4 can precisely drive the correction roller assembly 2 to rotate in a horizontal plane, thereby achieving fine-tuning of the substrate position and ensuring that the substrate remains on the ideal path throughout the entire transmission process.
[0059] In some embodiments, the alignment roller assembly 2 includes at least one alignment roller, each of which is rotatably mounted on two alignment roller positioning frames 24, and the substrate is supported on the alignment roller. In this embodiment, the substrate can be directly transported through the alignment roller, which can transport substrates with top-coated slurry, thereby realizing the transport of substrates with single-sided slurry coating.
[0060] In some embodiments, the alignment roller is a hollow air-bearing roller, the inner cavity of which is connected to a ventilation mechanism. The air-bearing roller ejects gas through airflow holes, forming an air cushion between the substrate and the air-bearing roller. This reduces direct contact between the substrate and the air-bearing roller, thereby reducing friction and the risk of scratches and wear on the substrate surface.
[0061] There are three air flotation rollers: a first air flotation roller 21, a second air flotation roller 22, and a third air flotation roller 23. The substrate is wound around the top of the first air flotation roller 21, around the bottom of the second air flotation roller 22, and then around the top of the third air flotation roller 23. Multiple airflow holes 25 are provided at the contact positions of the first air flotation roller 21, the second air flotation roller 22, and the third air flotation roller 23 with the substrate, and the airflow holes 25 communicate with the inner cavity of the air flotation roller.
[0062] In this embodiment, the substrate is wound around three air-floating rollers, which enables the substrate to be completely suspended, allowing the substrate with double-sided coating slurry to be transported, thereby achieving the drying of the substrate with double-sided coating slurry.
[0063] When the heights of the first air flotation roller 21, the second air flotation roller 22, and the third air flotation roller 23 are all aligned, the spacing between them is small. When the substrate is wound around the first air flotation roller 21, the second air flotation roller 22, and the third air flotation roller 23, the slurry on the substrate tends to stick to the two adjacent air flotation rollers when the substrate floats up, affecting the transmission effect of the substrate.
[0064] To prevent the slurry on the substrate from adhering to the air flotation rollers, in some embodiments, the first air flotation roller 21 and the third air flotation roller 23 are at the same height, while the second air flotation roller 22 is lower than the height of the first air flotation roller 21 and the third air flotation roller 23. In this embodiment, because the second air flotation roller 22 is lower than the first air flotation roller 21 and the third air flotation roller 23, adjacent air flotation rollers are staggered in the height direction. As the substrate passes over these air flotation rollers, it forms a natural undulation, effectively preventing the slurry from contacting adjacent air flotation rollers when the substrate floats, thereby reducing the risk of slurry adhesion.
[0065] The airflow holes on the first air-bearing roller 21 have an opening range greater than 90°, the airflow holes on the second air-bearing roller 22 have an opening range greater than 180°, and the airflow holes on the third air-bearing roller 23 have an opening range greater than 90°. This allows the gas blown out of the airflow holes on the first air-bearing roller 21 to form convection with the gas blown out of the airflow holes on the second air-bearing roller 22, and the gas blown out of the airflow holes on the second air-bearing roller 22 to form convection with the gas blown out of the airflow holes on the third air-bearing roller 23. This ensures that the airflow on both sides of the substrate is consistent, guaranteeing that the substrate is always in the middle position between the first air-bearing roller 21 and the second air-bearing roller 22, and between the second air-bearing roller 22 and the third air-bearing roller 23.
[0066] In some embodiments, the ventilation mechanism includes a duct 11 and a fan. The duct 11 is disposed on the housing 1 and connected to the interfaces on both sides of the air flotation roller, thereby communicating with the inner cavity of the air flotation roller. The housing 1 serves as the overall appearance of the equipment, ensuring a sealed internal space. The air flotation roller is connected to the housing via ducts, etc., providing airflow for stable suspension of the substrate. The fan is disposed at the end of the duct 11. The fan is a high-pressure fan, but other types of fans may also be used. The external fan provides airflow, which is delivered to the inner cavity of the air flotation roller through the duct 11 and then discharged from the airflow holes on the air flotation roller, providing blowing force to blow the substrate away from the surface of the air flotation roller. After the substrate moves a certain distance from the surface of the air flotation roller, it reaches a stable state, thus suspending the substrate.
[0067] In some embodiments, the first air flotation roller 21, the second air flotation roller 22 and the third air flotation roller 23 are each uniformly arranged with a plurality of airflow holes 25, so that the airflow blown out by the first air flotation roller 21, the second air flotation roller 22 and the third air flotation roller 23 is very uniform and stable.
[0068] In some embodiments, the second air flotation roller 22 is height-adjusted by a lifting structure, thereby adjusting the height of the second air flotation roller 22 to a suitable height position. The reasonable height difference ensures that the substrate is always in the optimal position of air cushion support during the transmission process, further reducing the possibility of the slurry coming into contact with the surface of the air flotation roller.
[0069] In some embodiments, the correction mechanism further includes a correction frame 3. More specifically, the correction frame 3 is a steel frame with high support strength. The correction frame 3 is divided into an upper frame 31 and a lower frame 32. The lower frame 32 serves a fixing function. The correction roller assembly 2 is mounted on the upper frame 31. The driving end of the drive assembly 4 is hinged to the upper frame 31, and the fixed end of the drive assembly 4 is hinged to the lower frame 32 via a connecting rod 322. A slide rail 311 is provided at each of the four corners of the upper frame 31. The driving end of the drive assembly 4 is connected to the connecting rod 322, and the end of the connecting rod is hinged to the upper frame 31. Rollers 321 are provided on the lower frame 32, and the four rollers 321 are slidably mounted in the four slide rails 311.
[0070] The movement trajectory of the upper frame 31 is as follows Figure 5 As shown, the drive assembly 4 provides power to push or retract the connecting rod 322, thereby driving the upper frame 31 and the air-bearing roller to move. The rollers connected at the four corners of the upper frame 31 and the lower frame 32 will move along the set trajectory, driving the air-bearing roller to move and realize the substrate correction.
[0071] Drive assembly 4 is a reciprocating drive assembly. When drive assembly 4 drives connecting rod 322 to reciprocate, roller 321 moves within slide rail 311, thereby causing upper frame 31 to rotate relative to lower frame 32, which in turn drives the correction roller assembly 2 to rotate. Drive assembly 4 is an electric cylinder, specifically a BFW80L-Stroke-8000-V1 series actuator. The electric cylinder includes a servo motor, reducer, ball screw, and piston rod. When the electric cylinder is running, the servo motor starts to rotate after receiving instructions from the control system. The rotational motion of the servo motor is reduced by the reducer, and the reduced rotational motion is converted into linear motion by the lead screw. The lead screw drives the piston rod to move linearly along the guide rail, realizing the push-pull action.
[0072] In some embodiments, a correction sensor bracket 6 is provided at the substrate inlet and / or substrate outlet. The correction sensor bracket 6 is located on the side of the substrate extending from the air flotation roller and is fixedly mounted on the housing to prevent excessive distance from the air flotation roller, facilitating detection. A correction sensor 5 is provided on the correction sensor bracket 6. The correction sensor 5 can be a photoelectric sensor, laser sensor, etc. The correction sensor 5 is used to detect the position of the substrate edge, determine whether the substrate has shifted, and feed back the detected shift information to the control system so that the control system can control the correction mechanism to correct the substrate. When substrate shift is detected, the correction mechanism will correct the substrate, and the correction sensor will again detect whether the corrected substrate has returned to its correct position.
[0073] The web-aligning sensor is compatible with substrates ranging from 400mm to 600mm in width. Therefore, the sensor position needs to be adjusted according to the substrate width. To address this, in some embodiments, the web-aligning sensor support 6 is connected to a web-aligning sensor moving structure 7, which is used to adjust the positions of the web-aligning sensor support 6 and the web-aligning sensor 5. When the substrate specifications change, the position of the web-aligning sensor 5 is adjusted via the web-aligning sensor moving structure 7 to ensure alignment, making the web-aligning sensor 5 suitable for substrates of different sizes and types.
[0074] The moving structure 7 of the correction sensor can be a lead screw drive structure, including a lead screw, a lead screw nut and a power source. The lead screw nut is connected to the correction sensor bracket 6. The power source is a motor. The motor drives the lead screw to rotate. When the lead screw rotates, it drives the lead screw nut to rotate. In turn, the lead screw nut drives the correction sensor bracket 6 to adjust its position, thereby aligning the detection point on the correction sensor 5 with the substrate.
[0075] In some embodiments, at least one pair of correction sensors 5 are provided, with the two correction sensors 5 in each pair located on both sides inside the housing 1. In this embodiment, the correction sensors 5 are arranged in pairs, which can detect the position status of the two sides of the substrate respectively, ensuring that the offset of the substrate in the entire width direction can be accurately captured.
[0076] According to an embodiment of the present invention, in a second aspect, an oven system is provided, including a substrate oven and a correction oven. The substrate oven has a substrate conveying channel inside. At least one correction oven is provided, and the correction oven is disposed between two adjacent substrate oven sections along the direction of the substrate conveying channel.
[0077] In this embodiment, one or more correction ovens can be installed inside two adjacent substrate drying ovens. This ensures both airtightness during correction and enhances the correction effect. The positions of the correction ovens are arranged based on the length of the substrate drying oven. For example, for a substrate drying oven that is hundreds of meters long, two correction ovens can be placed at 1 / 3 and 2 / 3 of the length of the substrate drying oven to perform correction work.
[0078] The specific correction process for the substrate in this utility model is as follows:
[0079] When the equipment is started, the correction sensor bracket 6 and the correction sensor 5 are adjusted to the preset optimal detection position by the correction sensor moving structure 7. This ensures that each pair of correction sensors 5 is located on both sides of the substrate, enabling simultaneous detection of the position status of both sides of the substrate.
[0080] The substrate enters the conveying system from the feed port of the substrate drying oven.
[0081] The correction sensor 5 begins real-time monitoring of the edge positions on both sides of the substrate, acquiring information on the lateral offset of the substrate, and transmitting this information to the control system. The control system then determines whether the substrate has shifted, as well as the direction and magnitude of the shift.
[0082] The control system sends commands to the correction mechanism based on the offset and direction. The control system controls the drive assembly 4 to rotate the upper frame 31, thereby correcting the alignment of the correction roller assembly 2 and the substrate above the upper frame 31.
[0083] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
