Description

Technical Field

[0001] This utility model belongs to the technical field of battery production equipment, specifically relating to an oven. Background Technology

[0002] During the use of the folding coating machine, the wet film electrode strips in the lower layer of the oven break off. The powder attached to the wet film electrode strips contaminates the oven body and air nozzles. Whether it is the consistency of the required air speed, the contamination of the equipment by the uncured powder attached to the wet film electrode strips, or the powder scattering and adhering to the equipment and electrode surface after the electrode strips break off, these situations have a significant negative impact on the production process.

[0003] The main approach adopted in the relevant technologies is a passive solution, which involves designing tools to manually clean and wipe the fallen powder and residue. This is not only inefficient but also requires highly skilled personnel and reduces the degree of automation of the equipment. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0019] The terms "first," "second," etc., used in the specification and claims of this utility model are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this utility model can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, the first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0020] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings, through specific examples and application scenarios.

[0021] This application provides an oven, see embodiments thereof. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the drying oven provided in an embodiment of this application; Figure 2The image shows a second support surface formed by a support roller at a first height and a first support surface formed by a support roller at a second height in an oven. Specifically, the oven includes: a chamber 10, an adsorption mechanism 20, a lifting mechanism 30, and multiple support rollers 40; the chamber 10 is provided with an inlet 101 and an outlet 102, which are located at the same end of the chamber 10. The oven has a height direction Z that is perpendicular to the ground, and the inlet 101 and outlet 102 are located at different heights along the height direction Z; a portion of the support rollers 40 are located at a first height H1 position of the chamber 10 to form a first support surface 401, and another portion of the support rollers 40 are located at a second height H2 position of the chamber 10 to form a second support surface 402, wherein the plane of the second support surface 402 is located above the plane of the first support surface 401 along the height direction Z; the adsorption mechanism 20 is located on the side of the first support surface 401 close to the second support surface 402, and the lifting mechanism 30 is located on both sides of the first support surface 401. Both the adsorption mechanism 20 and the lifting mechanism 30 are fixedly connected to the chamber 10.

[0022] The chamber 10 is the main structure of the drying oven, providing a mounting base for internal components such as the support roller 40, adsorption mechanism 20, and lifting mechanism 30. It also forms a relatively enclosed drying space, ensuring the stability of the drying environment. The inlet 101 and outlet 102 of the chamber 10 are channels for the electrode 100 to enter and exit the drying oven. The inlet 101 and outlet 102 are located at the same end of the chamber 10 but at different heights. The outlet 102 corresponds to the first support surface at the first height H1, and the inlet 101 corresponds to the second support surface at the second height H2. This arrangement facilitates the electrode 100 entering and exiting the drying oven from the same side. Specifically, the electrode 100 enters the drying oven through the inlet 101 at the second height H2, is transported by the rolling of the support roller 40, and exits the drying oven through the outlet 102 at the lower first height H1. This design, which allows the electrode 100 to be folded at least once during the baking process, enables the electrode 100 to extend its transmission distance within the oven space, increase drying time, improve baking efficiency, and enhance the drying effect of the electrode 100, while also reducing the energy consumption of the oven during baking, all within a limited space, while also reducing the drying effect of the electrode 100.

[0023] The second support surface 402 is formed by the support rollers 40 at the second height H2 and is the first support surface that the electrode 100 contacts after entering the oven; the first support surface 401 is formed by the support rollers 40 at the first height H1. During the baking and heating process, the first support surface 401 and the second support surface 402 contact the side of the electrode 100 that is not coated with slurry, avoiding direct friction or contamination of the slurry-coated surface by the support components, and effectively protecting the side of the electrode 100 coated with slurry from contamination or damage.

[0024] Because the electrode 100 is folded at least once inside the oven, the portion of the electrode 100 supported by the first support surface 401 may break or crumble during the process from the second support surface 402 to the first support surface 401. If the electrode 100 is not completely dry during the baking process, the powder attached to it when it falls can contaminate the chamber 10 and the heating nozzle. If it falls above the heating nozzle due to gravity, it may clog the nozzle, affecting the consistency of the airflow during subsequent baking. Alternatively, dust particles may be adsorbed by the incompletely dried electrode 100, resulting in foreign particles on or inside the electrode 100 after drying, causing quality defects.

[0025] An adsorption mechanism 20 is provided on the side of the first support surface 401 near the second support surface 402. When the electrode 100 is detected to be broken or fallen, it can hold the electrode 100 by means of negative pressure adsorption, etc., to prevent the electrode 100 from falling and contaminating the heating nozzle and the housing 10. Lifting mechanisms 30 are provided on both sides of the first support surface 401. When the electrode 100 falls, the lifting mechanism 30 clamps the electrode 100 from both sides of the electrode 100 to avoid contaminating the heating nozzle and the housing 10.

[0026] In addition, the adsorption mechanism 20 and the lifting mechanism 30 can cooperate with each other to provide a double guarantee in the process of preventing the electrode 100 from falling. When one of them fails or is damaged, the other can still prevent the electrode 100 from falling.

[0027] Therefore, in summary, the oven provided in this application embodiment, through the adsorption mechanism 20 and the lifting mechanism 30 arranged opposite to each other, when the electrode 100 breaks and falls, the adsorption mechanism 20 can adsorb the broken electrode 100, providing a certain adsorption force to keep the electrode 100 suspended, thereby preventing the broken wet film electrode 100 from falling; the lifting mechanism 30 lifts the broken electrode 100 upwards. The mutual cooperation between the adsorption mechanism 20 and the lifting mechanism 30 achieves the prevention of the broken wet film electrode 100 from falling, effectively reducing the contamination of the equipment by the broken electrode 100.

[0028] Optionally, refer to Figure 1 and Figure 3 , Figure 3 This is a schematic diagram of the adsorption structure in the oven provided in an embodiment of this application. The adsorption mechanism 20 includes: a fan 201, a transmission pipeline 202, and an adsorption element 203; the fan 201 is connected to the transmission pipeline 202, the transmission pipeline 202 is fixedly connected to the housing 10, and the adsorption element 203 is connected to the transmission pipeline 202; the adsorption element 203 is disposed on the side of the first support surface 401 near the second support surface 402, and the adsorption element 203 includes an adsorption port 2031 facing the first support surface 401.

[0029] The adsorption element 203 is disposed on the side of the first support surface 401 near the second support surface 402, and the adsorption port 2031 faces the first support surface 401, that is, directly opposite the side of the electrode 100 that is not coated with slurry. When the electrode 100 breaks, the fan 201 provides negative pressure to the adsorption element 203 through the transmission pipeline 202, causing the adsorption port 2031 to generate an adsorption force, which attracts the side of the electrode 100 that is not coated with slurry.

[0030] The negative pressure provided by the fan 201 generates an adsorption force at the moment the electrode 100 breaks, quickly adsorbing the broken electrode 100 near the adsorption element 203, preventing it from falling freely or drifting randomly, and avoiding entanglement or collision with other components. The adsorption force only acts on the side of the electrode 100 that is not coated with slurry, which can prevent the adsorption element from directly contacting the coated surface, thereby preventing the incompletely dried slurry from contaminating the adsorption element 203.

[0031] During normal transport, the adsorption force can be set to a low-intensity state to assist in stabilizing the electrode 100, without interfering with its normal movement. When the electrode 100 breaks, the adsorption force can be enhanced through sensor linkage or manual triggering, quickly switching to a high-intensity state to precisely match the needs of the breakage condition. After the adsorption mechanism 20 adsorbs and fixes the broken electrode 100, it can maintain the electrode 100 in a relatively regular state, making it easy for operators to quickly locate the breakage position and remove the fragment, reducing downtime for maintenance.

[0032] Optionally, refer to Figure 3 The adsorption mechanism 20 also includes a collection box 204, which is connected to the fan 201.

[0033] During the normal transport or breakage of electrode 100, a small amount of dust and debris may fall off the surface of electrode 100, such as substrate debris and edge lint on the uncoated side. After electrode 100 breaks, when the adsorption mechanism 20 adsorbs and transports the broken fragments to the direction of the fan 201 through negative pressure, the collection box 204 can intercept and store smaller fragments. Specifically, the collection box 204 is connected to the air outlet of the fan 201. The fan 201 generates negative pressure at the air inlet and positive pressure at the air outlet. This pressure difference drives air to flow in from the adsorption port 2031 of the adsorption element 203, forming a directional airflow. Under negative pressure, dust, debris, and other impurities are drawn into the adsorption port 2031 and enter the transmission pipeline 202 with the airflow. Since the transmission pipeline 202 is connected to the air inlet of the fan 201, the airflow carries the impurities forward and enters the fan through the pipeline. Because the transmission pipeline 202 is connected to the fan 201, the fan 201 is connected to the collection box 204. The impurities pass through the fan 201 with the airflow and enter the collection box 204 from the air outlet of the fan 201, preventing them from circulating with the airflow or overflowing from the pipeline gaps and polluting the internal environment of the oven. In particular, it can also prevent dust particles from being adsorbed by the incompletely dried electrode 100, which would cause foreign particles to appear on the surface or inside of the electrode 100 after drying, resulting in quality defects of the electrode 100.

[0034] The collection box 204 can be designed as a detachable component. The collection box 204 and the fan 201 can be connected by a snap-fit. The edge of the collection box 204 is provided with elastic snaps, and a corresponding slot is provided at the interface of the fan 201. During assembly, the snaps and slots are engaged to achieve quick fixation. During disassembly, the snaps can be pressed to separate them. Alternatively, the collection box 204 and the fan 201 can be connected by a thread. The opening of the collection box 204 is machined with external threads, and the interface of the fan 201 is provided with internal threads. Tightening or disassembly can be achieved by rotation. During use, the operator does not need to disassemble the fan 201 or the transmission pipeline 202. Maintenance can be completed by periodically cleaning the collection box 204, reducing equipment downtime and maintenance complexity.

[0035] Optionally, refer to Figure 3 The transmission pipeline 202 includes two first sub-pipelines 2021 and a second sub-pipeline 2022, and two adsorption elements 203. The second sub-pipeline 2022 is disposed between the two first sub-pipelines 2021 and connects the two first sub-pipelines 2021. The first sub-pipelines 2021 and the adsorption elements 203 are connected.

[0036] Two adsorption elements 203 are connected to two first sub-pipes 2021 respectively, dividing the adsorption area of ​​the electrode 100 into two adsorption areas. A second sub-pipe 2022 connects the two first sub-pipes 2021, allowing the negative pressure generated by the fan 201 to be evenly distributed to the two first sub-pipes 2021 through the second sub-pipe 2022, resulting in a more uniform adsorption force between the two adsorption elements 203. Compared to a single adsorption element 203, two adsorption elements 203 can cover a larger area in the width direction of the electrode 100, such as the two sides or different positions of the electrode 100, avoiding excessive localized stress or unstable adsorption due to a single adsorption point.

[0037] The second sub-pipeline 2022 connects to the two first sub-pipelines 2021, forming a "parallel" pipeline structure. Even if one of the first sub-pipelines 2021 or the adsorption element 203 experiences a slight blockage, such as the adhesion of electrode 100 debris, the negative pressure can still be transmitted to the other adsorption element 203 through the second sub-pipeline 2022, ensuring that at least one adsorption point works effectively and reducing the risk of adsorption failure due to a single first sub-pipeline 2021 malfunction.

[0038] Optionally, refer to Figure 4 , Figure 4 This is a schematic diagram of a lifting mechanism 30 in an oven according to an embodiment of this application. The lifting mechanism 30 includes: a first driving member 301, a first clamping member 302, and a second clamping member 303; the first clamping member 302 and the second clamping member 303 are arranged opposite each other along the height direction Z, the first clamping member 302 is disposed on the side of the first support surface 401 close to the second support surface 402, and the first clamping member 302 is fixedly connected to the box body 10; the first driving member 301 and the second clamping member 303 are both disposed on the side of the first support surface 401 away from the second support surface 402, the first driving member 301 is fixedly connected to the box body 10, the first driving member 301 is fixedly connected to the second clamping member 303, and the first driving member 301 drives the second clamping member 303 to move along the height direction Z.

[0039] The first clamping member 302 is fixed on the side of the first support surface 401 near the second support surface 402. When the electrode 100 breaks and falls, the first driving member 301 drives the second clamping member 303 to move upward along the height direction Z. It cooperates with the first clamping member 302 to form a clamp from both sides of the electrode 100, clamping the fallen electrode 100 and preventing it from falling to the bottom of the housing 10, getting caught in the gap of the support roller 40, or getting tangled in other parts, thus reducing the risk of equipment jamming.

[0040] If the electrode 100 is only partially drooping and has not completely fallen off, or if it needs to be manually removed after falling off, the lifting mechanism 30 can adjust the position of the electrode 100 by lifting it. At this time, the first driving member 301 drives the second clamping member 303 to move upward, lifting the edge or part of the fallen electrode 100 from below the electrode 100, that is, from the side of the first support surface 401 away from the second support surface 402, so that it is removed from the dangerous position.

[0041] It should be noted that the first driving component 301 can be a cylinder, an electric push rod, or a servo motor combined with a ball screw assembly, etc., and this application embodiment does not make specific limitations. This can satisfy the reciprocating motion requirement along the height direction Z, and can also achieve displacement adjustment of the second clamping component 303 through precise control of the stroke.

[0042] Optionally, refer to Figure 5 , Figure 5 This is a schematic diagram of a pressing mechanism in an oven according to an embodiment of this application. The oven further includes a pressing mechanism 50; the pressing mechanism 50 is disposed at one end of a plurality of support rollers 40 away from the feed inlet 101; the pressing mechanism 50 includes a second driving member 501, a support member 502, a first connecting member 503, and a pressing roller 504; the support member 502 is fixedly connected to the chamber 10, the second driving member 501 is fixedly connected to the support member 502, the first connecting member 503 is rotatably connected to the pressing roller 504, and the first connecting member 503 is slidably connected to the second driving member 501.

[0043] When the electrode 100 breaks, the electrode 100 on the second support surface 402 may continue to be transmitted due to inertia due to loss of tension, resulting in the broken end becoming loose, wrinkled, or rolled into the equipment. The second drive member 501, as a power source, can quickly drive the first connector 503 to move the lower pressure roller 504 in a direction close to the support roller 40, so that the lower pressure roller 504 quickly contacts the electrode 100 on the second support surface 402 and applies pressure. The contact area between the lower pressure roller 504 and the electrode 100 is large and is a rolling contact, which can form uniform pressure on the surface of the electrode 100, avoiding excessive local force that could damage the electrode 100. At the same time, it reliably prevents the electrode 100 on the second support surface 402 from continuing to be transmitted through friction, achieving an immediate pause.

[0044] The support 502 is fixedly connected to the housing 10, providing rigid support for the entire pressing mechanism 50, ensuring no shaking or deviation during pressing, and avoiding the bias of the electrode 100 due to the displacement of the mechanism itself.

[0045] During normal transmission of the electrode 100, the second driving component 501 can drive the lower pressure roller 504 to be in a raised state, that is, the lower pressure roller 504 maintains a gap or slight contact with the electrode 100. The sliding structure of the first connecting component 503 allows the lower pressure roller 504 to adaptively adjust with the slight fluctuations of the electrode 100, without affecting the normal operating speed and transmission flatness of the electrode 100, avoiding a decrease in production efficiency due to excessive intervention of the protection mechanism. When a fault occurs in the transmission of the electrode 100, it can quickly press down to stop the transmission, thus improving the operational safety and reliability of the oven.

[0046] Optionally, refer to Figure 6 The oven also includes a reversing roller 60 and a third drive unit 70; the reversing roller 60 is located on the side of the plurality of support rollers 40 away from the discharge port 102, and the reversing roller 60 is located on the side of the pressing mechanism 50 close to the support rollers 40. The reversing roller 60 is rotatably connected to the box body 10; the third drive unit 70 and the reversing roller 60 are fixedly connected.

[0047] The reversing roller 60 is installed on the side of the support roller 40 away from the discharge port 102 and on the side of the pressing mechanism 50 close to the support roller 40, serving to deflect the electrode 100 during transport. The reversing roller 60 guides the electrode 100 to form a zigzag transport path within the housing 10. For example, after entering from the feed port 101, the electrode 100 is deflected by the reversing roller 60 via the first support surface 401, then via the second support surface 402, and finally output from the discharge port 102. This extends the transport distance of the electrode 100 within the limited space of the housing 10, increasing drying time and thus improving drying uniformity and thoroughness. During the reversing process, the reversing roller 60 rolls against the side of the electrode 100 that is not coated with slurry. The reversing roller 60 is rotatably connected to the housing 10 to ensure the stability of its rotation axis and prevent the electrode 100 from shifting in the transmission direction due to shaking. At the same time, its position is on the side of the pressing mechanism 50 close to the support roller 40, which can form a continuous transmission support point with the support roller 40 and the pressing roller 504, reducing the suspended section of the electrode 100 during the transmission process and further ensuring the smoothness of the transmission.

[0048] The third drive component 70 is fixedly connected to the reversing roller 60, providing rotational power to the reversing roller 60. By adjusting the output speed of the third drive component 70, the linear speed of the reversing roller 60 is kept consistent with the transmission speed of the support roller 40 and the electrode 100, avoiding the electrode 100 from loosening or being overstretched due to speed differences, and ensuring the tension stability of the electrode 100 during transmission.

[0049] Optionally, refer to Figure 6 The oven also includes a tension detection mechanism 80, which is fixedly connected to the reversing roller 60.

[0050] The tension detection mechanism 80 is fixed to the reversing roller 60 and can sense the change in tension exerted by the electrode 100 on the reversing roller 60, outputting tension data in real time. When the tension exceeds the preset threshold, a sudden increase indicates that the electrode 100 is about to break, while a continuous decrease indicates that it may loosen. The control system can trigger an early warning to remind the operator to intervene in time and prevent the fault from escalating.

[0051] When a sudden drop in tension to zero or below the breakage threshold is detected, a protection mechanism can be immediately triggered. This includes instructing the pressing mechanism 50 to press down on the upper electrode 100, the adsorption mechanism 20 to strengthen adsorption, and the third driving component 70 to stop driving. This is faster and more accurate than manual observation or other indirect detection methods. The addition of the tension detection mechanism 80 not only enhances the precise control over the transmission process of the electrode 100 but also improves the equipment's fault warning and response capabilities.

[0052] Optionally, refer to Figure 6 The tension detection mechanism 80 includes: a detector 801, a fixing member 802, and a second connecting member 803; the detector 801 is fixedly connected to the fixing member 802, the fixing member 802 is fixedly connected to the housing 10, the second connecting member 803 is movably connected to the detector 801, and the second connecting member 803 is fixedly connected to the reversing roller 60.

[0053] The tension of the electrode 100 during transmission is transmitted to the second connector 803 via the reversing roller 60. The second connector 803 is movably connected to the detector 801. This design allows tension changes to be efficiently converted into physical signals that the detector 801 can recognize. For example, when the tension of the electrode 100 increases, the reversing roller 60 experiences a greater pulling force, which pushes or pulls the detector 801 via the second connector 803, enabling the detector 801 to accurately sense the magnitude of the force change. The movable connection avoids signal attenuation caused by rigid transmission, ensuring that even minute tension fluctuations can be captured, thus improving detection sensitivity.

[0054] The rigid connection between the fixing member 802 and the housing 10 provides stable support for the entire detection mechanism, preventing damage to internal components of the detector 801 due to shaking under force. The movable connection of the second connecting member 803 can buffer instantaneous tension impacts, such as the sudden change in tension when the electrode 100 suddenly breaks, reducing the direct impact of the impact force on the detector 801, protecting the core sensing components, and extending their service life.

[0055] Optionally, the oven also includes a controller; the controller is electrically connected to the tension detection mechanism 80, the adsorption mechanism 20, and the lifting mechanism 30; the controller is used to receive signals from the tension detection mechanism 80 and send signals to the adsorption mechanism 20 and the lifting mechanism 30. When the tension detection mechanism 80 detects that the electrode 100 is broken, the controller sends a signal to make the adsorption mechanism 20 and the lifting mechanism 30 move.

[0056] When the detector 801 in the tension detection mechanism 80 detects a sudden drop or disappearance of tension, the detector 801 sends a signal to the controller that the electrode 100 is broken. The controller then sends signals to the adsorption mechanism 20 and the lifting mechanism 30. The adsorption mechanism 20 quickly increases the negative pressure and adsorbs the uncoated surface of the broken electrode 100 through the adsorption member 203 to prevent it from falling or drifting. The first drive member 301 of the lifting mechanism 30 drives the second clamping member 303 to move upward, which cooperates with the first clamping member 302 to clamp the electrode 100 and further fix the broken electrode 100.

[0057] Furthermore, the controller sends signals to the adsorption mechanism 20 and the lifting mechanism 30, and the coordinated movement of the adsorption mechanism 20 and the lifting mechanism 30 to prevent the broken electrode from falling can also be combined with other mechanisms of the oven to form a full-process protection. For example, when the detector 801 in the tension detection mechanism 80 detects a sudden drop or disappearance of tension, the controller sends signals to the pressing mechanism 50, the third drive member 70, etc. After receiving the signal, the pressing mechanism 50 drives the second drive member 501 to drive the first connecting member 503 to move the pressing roller 504 in the direction close to the support roller 40, so that the pressing roller 504 quickly contacts the electrode 100 on the second support surface 402 and applies pressure to prevent the electrode 100 on the second support surface 402 from continuing to be transmitted; after receiving the signal, the third drive member 70 stops outputting power, the reversing roller 60 stops rotating, and the electrode 100 on the second support surface 402 stops being transmitted.

[0058] This method of inter-component coordination improves response speed, action consistency, and processing reliability. The controller sends signals to multiple components, and the movement of these components ensures that if some components malfunction, other normally functioning components can also prevent the broken wet film electrode 100 from falling off, effectively reducing the contamination of the equipment by the broken electrode 100.
