Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, specifically providing a baking device. Background Technology

[0002] The lithium battery production process is lengthy and involves numerous pieces of equipment. The quality of lithium battery drying equipment has a significant impact on lithium battery performance and cost, making it one of the key pieces of equipment in lithium battery production. Moisture in lithium batteries can cause irreversible damage to their capacity, cycle life, and safety. Therefore, moisture control during battery manufacturing is an extremely important aspect of lithium battery production.

[0003] Roll-to-roll online baking effectively improves the consistency of the baked electrodes. A common roll-to-roll online baking method uses a hot oil roller as a heat source. To ensure heating efficiency, the electrode and the oil roller are continuously bonded at a large 180° wrap angle. Due to static friction, the large wrap angle makes it difficult to transmit tension, and the high temperature causes the electrode to expand, leading to uncontrolled internal tension and the risk of abnormal belt movement (wrinkling, loosening, tightness, etc.). Furthermore, because the oven is at a high temperature, it is difficult to add other tension control components.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the above-mentioned technical problems, and to address the issue of uncontrolled tension of the electrode sheets in existing ovens, which poses a risk of abnormal belt movement.

[0006] This utility model provides a baking device, including a box body, a conveyor roller, a heating element, and a drive assembly; the box body has an electrode inlet and an electrode outlet on both sides respectively;

[0007] Multiple conveyor rollers are provided, and the multiple conveyor rollers are rotatably arranged inside the box. The conveyor rollers are configured to convey the electrode sheets to be dried.

[0008] The heating element is disposed in the housing and is configured to heat the electrode sheet to be dried;

[0009] The drive assembly is driven to the conveyor roller, and the drive assembly is configured to control the rotational speed of the conveyor roller.

[0010] By employing the above technical solution, the drive assembly can drive the conveyor rollers to different speeds. The speed of the different conveyor rollers gradually increases along the belt direction of the electrode to be dried. Even if the electrode to be dried gradually elongates as the temperature inside the chamber rises, the tension of the electrode to be dried can be effectively maintained, thereby preventing the electrode from falling off the conveyor rollers or wrinkling. This greatly reduces the risk of belt conveyor abnormalities and ensures the stability and continuity of production.

[0011] In a specific embodiment of the baking equipment described above, there are multiple driving components, and each driving component is arranged in a one-to-one correspondence with a conveyor roller.

[0012] By adopting the above technical solution, the rotational speed of a single conveyor roller can be adjusted through a one-to-one correspondence between the drive components and the conveyor rollers.

[0013] In a specific embodiment of the above-described baking equipment, the drive assembly includes a drive motor and a gearbox, the drive motor is connected to the gearbox, and the gearbox is connected to a plurality of the conveyor rollers, or

[0014] The drive assembly includes a drive motor, and the drive motor is configured in a one-to-one correspondence with the conveyor roller.

[0015] By employing the above technical solution, the rotational speed of different conveyor rollers is controlled through a one-to-one correspondence between the drive motor and the conveyor roller, enabling the conveyor rollers to achieve optimal rotational speeds. Connecting the drive motor to the gearbox, and then connecting the gearbox to multiple conveyor rollers, reduces the number of drive motors required, thus saving costs.

[0016] In a specific embodiment of the baking equipment described above, the diameter of all or part of the conveyor rollers gradually increases along the belt direction of the electrode sheet to be dried.

[0017] With the above-mentioned technical solution, the electrode sheets to be dried gradually elongate as the temperature inside the chamber increases. In the direction of electrode sheet transport, the diameter of the conveyor rollers gradually increases. This ingenious design ensures that even after the electrode sheets elongate, they remain wrapped around the conveyor rollers. This effectively maintains the tension of the electrode sheets to be dried, thus preventing them from detaching from the conveyor rollers or wrinkling. It greatly reduces the risk of belt transport abnormalities and ensures the stability and continuity of production.

[0018] In a specific embodiment of the baking equipment described above, the diameter of the adjacent conveyor roller along the conveying direction of the electrode to be dried is increased by any value between 0.03 mm and 0.05 mm.

[0019] In a specific embodiment of the baking equipment described above, the conveyor roller includes an upper conveyor roller and a lower conveyor roller, which are spaced apart. The electrode sheet to be dried alternately travels on the upper conveyor roller and the lower conveyor roller, thereby forming an S-shaped conveyor.

[0020] When the above technical solution is adopted, the S-shaped conveyor belt can increase the baking length of the electrode sheet to be dried in the chamber and improve the baking efficiency.

[0021] In a specific embodiment of the baking equipment described above, the upper conveyor roller and the lower conveyor roller are arranged in a manner that allows the electrode sheet to be dried to be conveyed in a vertical direction.

[0022] When the above technical solution is adopted, the electrode sheet to be dried is in close contact with the upper and lower conveyor rollers at a large wrap angle, which facilitates the drying of the electrode sheet.

[0023] In a specific embodiment of the baking equipment described above, the baking equipment further includes a temperature detection module, and the number of the temperature detection modules is multiple, with each of the multiple temperature detection modules used to detect the temperature of each of the conveyor rollers.

[0024] When the above technical solution is adopted, the temperature detection module detects the temperature of different conveyor rollers and adjusts the rotation speed of different conveyor rollers according to the detected temperature, so as to ensure the tension of the electrode sheet to be dried.

[0025] In a specific embodiment of the baking equipment described above, the heating element is disposed inside the conveyor roller and is configured to heat the conveyor roller.

[0026] When the above technical solution is adopted, the heating element is set inside the conveyor roller, which can save space inside the box. After the heating element heats the conveyor roller, the conveyor roller heats the electrode sheet to be dried.

[0027] In a specific embodiment of the baking equipment described above, the baking equipment further includes a steering roller, which is disposed inside the housing and close to the electrode inlet and the electrode outlet, respectively. The steering roller contacts the electrode to be dried and is configured to change the belt direction of the electrode to be dried.

[0028] When the above technical solution is adopted, after the electrode to be dried enters the chamber, it first passes through a guide roller so that the electrode to be dried can pass through the electrode to be dried in a set direction. Before the electrode to be dried exits the chamber, it finally passes through another guide roller so that the electrode to be dried passes through the electrode outlet in a set direction.

[0032] Preferred embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the upper conveyor rollers are described in combination as four in the specification, the number of upper conveyor rollers in this application can obviously be three, five, or six, etc.

[0033] It should be noted that, in the description of this application, unless otherwise explicitly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or other type of connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. Furthermore, in the description of this application, "multiple" refers to at least two. It should be understood that the terms "upper," "lower," "inner," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0034] Roll-to-roll online baking effectively improves the consistency of the baked electrodes. Common roll-to-roll online baking methods utilize hot oil rollers as a heat source, with the electrodes continuously bonded to the rollers at a large 180° wrap angle to ensure heating efficiency. However, due to static friction, this large wrap angle makes it difficult to transmit tension, and the high temperature causes electrode expansion, leading to uncontrolled internal tension and the risk of abnormal belt movement (wrinkling, loosening, tightness, etc.). Furthermore, because the oven is at a high temperature, it is difficult to add other tension control components.

[0035] It is important to understand that in existing technologies, the tension of the electrode sheets entering the drying chamber is typically controlled by the winding and unwinding devices. Without considering the friction between the oil rollers and the electrode sheets, the tension of the electrode sheets remains constant. However, due to the continuous 180° large wrap angle contact between the electrode sheets and the oil rollers, static friction affects the tension of the electrode sheets on different oil rollers. Due to the combined effects of the winding and unwinding devices and static friction, the point of minimum electrode tension generally occurs after the electrode sheets have passed through several oil rollers. At this point, the low electrode tension and the elongation of the electrode sheets during drying make them prone to wrinkling and loosening, posing a risk of belt slippage abnormalities.

[0036] like Figure 1 As shown, to address the problem of uncontrolled tension of the electrode sheets inside the housing 1 of existing baking equipment, which poses a risk of abnormal belt movement, this utility model provides a baking device, including a housing 1, conveyor rollers 2, a heating element (not shown in the figure), and a drive assembly; the housing 1 has electrode sheet inlets 12 and electrode sheet outlets 13 on both sides respectively; multiple conveyor rollers 2 are provided, and the multiple conveyor rollers 2 are rotatably arranged inside the housing 1, and the conveyor rollers 2 are configured to convey the electrode sheets 4 to be dried; the heating element is arranged in the housing 1, and the heating element is configured to heat the electrode sheets 4 to be dried; the drive assembly is drivenly connected to the conveyor rollers 2, and the drive assembly is used to control the rotational speed of the conveyor rollers 2.

[0037] In this way, the drive assembly can drive the conveyor rollers 2 to different speeds. The speed of the conveyor rollers 2 gradually increases along the belt direction of the electrode sheet 4 to be dried. Even if the electrode sheet 4 to be dried gradually elongates as the temperature inside the chamber 1 rises, the tension of the electrode sheet 4 to be dried can be effectively maintained, thereby preventing the electrode sheet 4 to be dried from falling off the conveyor rollers 2 or from wrinkling. This greatly reduces the risk of belt conveyor abnormalities and ensures the stability and continuity of production.

[0038] See further Figure 1 In a preferred embodiment of the baking equipment of this utility model, the baking equipment includes a box body, a conveying roller, a heating element, a driving assembly and a steering roller. On both sides of the box body 1, there are electrode inlets 12 and electrode outlets 13 at the same height. The electrode 4 to be dried enters the box body 1 from the electrode inlet 12 and exits the box body 1 through the electrode outlet 13.

[0039] Air ducts 14 are provided on both the upper and lower sides of the housing 1. An upper air vent 111 is provided on the upper air duct 14 of the housing 1, and a lower air vent 112 is provided on the lower air duct 14 of the housing 1. The air vents 111 and 112 allow air to circulate inside the housing 1, facilitating the discharge of moisture from the housing 1.

[0040] It should be noted that the installation of air duct 14 is not mandatory. Those skilled in the art can choose whether to install air duct 14 and the specific structure of air duct 14 based on the specific application scenario. For example, air duct 14 can be installed only on the upper side of housing 1, or only on the lower side of housing 1. Alternatively, air duct 14 can be installed outside housing 1, with the outlets of upper air inlet 111 and lower air inlet 112 communicating with the internal cavity of housing 1.

[0041] It should also be noted that the installation of the upper air vent 111 and the lower air vent 112 is not mandatory, and those skilled in the art can set them according to specific application scenarios. For example, only the upper air vent 111 or only the lower air vent 112 may be installed. Alternatively, the air duct 14 may be located outside the housing 1, and both the upper air vent 111 and the lower air vent 112 may be located inside the housing 1 and connected to the air duct 14.

[0042] Continue to refer to Figure 1 The conveyor rollers 2 include four upper conveyor rollers 21 and four lower conveyor rollers 22 spaced vertically. The four upper conveyor rollers 21 are located at the same height near the top inside the housing 1, and the two lower conveyor rollers 22 are located at the same height near the bottom inside the housing 1. The electrode sheets 4 to be dried alternately travel on the upper conveyor rollers 21 and lower conveyor rollers 22, forming an S-shaped travel pattern. The electrode sheets 4 to be dried are arranged vertically between the upper conveyor rollers 21 and lower conveyor rollers 22. The S-shaped travel pattern increases the baking length of the electrode sheets 4 to be dried within the housing 1, improving baking efficiency. The electrode sheets 3 to be dried are fitted with the upper conveyor rollers 21 and lower conveyor rollers 22 at large wrap angles, facilitating the drying of the electrode sheets 3. The diameter of all conveyor rollers 2 gradually increases by 0.04 mm along the travel direction of the electrode sheets 4 to be dried.

[0043] Specifically, by Figure 1 Viewed from left to right, the diameter of the first upper conveyor roller 21 is 0.04 mm larger than that of the first lower conveyor roller 22; the diameter of the second lower conveyor roller 22 is 0.04 mm larger than that of the first upper conveyor roller 21; the diameter of the second upper conveyor roller 21 is 0.04 mm larger than that of the second lower conveyor roller 22; the diameter of the third lower conveyor roller 22 is 0.04 mm larger than that of the second upper conveyor roller 21; the diameter of the third upper conveyor roller 21 is 0.04 mm larger than that of the third lower conveyor roller 22; the diameter of the fourth lower conveyor roller 22 is 0.04 mm larger than that of the third upper conveyor roller 21; and the diameter of the fourth upper conveyor roller 21 is 0.04 mm larger than that of the fourth lower conveyor roller 22.

[0044] It should be noted that the arrangement of the conveyor rollers 2 is not mandatory. Those skilled in the art can choose the number and specific structure of the conveyor rollers 2 based on the specific application scenario. For example, the number of upper conveyor rollers 21 can be three, five, or six, etc. Similarly, the number of lower conveyor rollers 22 can be three, five, or six, etc. Furthermore, multiple upper conveyor rollers 21 can be located at different heights near the upper side inside the housing 1. Again, multiple lower conveyor rollers 22 can be located at different heights near the lower side inside the housing 1. Finally, the electrode sheet 4 to be dried may pass through two upper conveyor rollers 21 and then one or two lower conveyor rollers 22.

[0045] It should also be noted that it is preferred that the diameter of all conveyor rollers 2 gradually increases along the belt travel direction of the electrode sheet 4 to be dried. Those skilled in the art may choose to have the diameter of some conveyor rollers 2 gradually increase along the belt travel direction of the electrode sheet 4, depending on the specific circumstances. For example, the diameter of the upper conveyor roller 21 gradually increases along the belt travel direction of the electrode sheet 4, while the diameter of the lower conveyor roller 22 remains the same. Alternatively, the diameter of the lower conveyor roller 22 gradually increases along the belt travel direction of the electrode sheet 4, while the diameter of the upper conveyor roller 21 remains the same. Furthermore, the conveyor rollers 2 located upstream of the electrode sheet 4 in the belt travel direction have the same diameter, while the diameter of the downstream conveyor rollers gradually increases.

[0046] The diameter of the conveyor roller 2 gradually increases by 0.04 mm along the belt direction of the electrode 4 to be dried, which is an example. The value of the gradual increase of the diameter of the conveyor roller 2 along the belt direction of the electrode 4 to be dried is determined according to the amount of growth of the electrode 4 to be dried during the drying process. Specifically, it can be 0.03 mm or 0.05 mm.

[0047] A heating element is disposed inside the conveyor roller 2 and is configured to heat the conveyor roller 2. The heating element is disposed inside the conveyor roller 2 and can heat the conveyor roller 2, which heats the electrode sheet 4 to be dried to the drying temperature for moisture removal.

[0048] It should be noted that the installation of a heating element is not mandatory, and those skilled in the art can choose the specific structure of the heating element based on the specific application scenario. For example, the heating element may consist of a heating element and a fan, with the fan transferring the heat from the heating element to the electrode sheet 4 to be dried. Alternatively, the heating element may include a heater and a heating medium, with a heating cavity inside the conveyor roller 2 for the flow of the heating medium. The heater is located outside the housing 1, and after heating the heating medium, it is conveyed into the heating cavity to heat the conveyor roller 2.

[0049] The number of drive components is the same as the number of conveyor rollers 2, with eight drive components corresponding one-to-one with each conveyor roller 2. Specifically, the drive components include adjustable speed drive motors, each corresponding to a conveyor roller 2. The drive motors can be stepper motors or servo motors, etc. This method of corresponding drive motors to each conveyor roller 2 controls the rotational speed of different conveyor rollers 2, ensuring that the conveyor rollers 2 reach their optimal speed and facilitating speed adjustment. The rotational speed of the conveyor rollers 2 gradually increases along the conveying direction of the electrode sheet 4 to be dried. Even as the electrode sheet 4 gradually elongates due to the rising temperature inside the chamber 1, the tension of the electrode sheet 4 can be effectively maintained, thus preventing the electrode sheet 4 from falling off the conveyor rollers 2 or wrinkling.

[0050] Specifically, by Figure 1 Viewed from left to right, the linear velocity of the first lower conveyor roller 22 is V1, and the linear velocity of the first upper conveyor roller 21 is V2; the linear velocity of the second lower conveyor roller 22 is V3; the linear velocity of the second upper conveyor roller 21 is V4; the linear velocity of the third lower conveyor roller 22 is V5; the linear velocity of the third upper conveyor roller 21 is V6; the linear velocity of the fourth lower conveyor roller 22 is V7; and the linear velocity of the fourth upper conveyor roller 21 is V8, where V1 < V2 < V3 < V4 < V5 < V6 < V7 < V8. The difference in linear velocity between two adjacent conveyor rollers 2 in the belt conveying direction of the electrode sheet 4 to be dried is less than the elastic deformation of the electrode sheet 4 to be dried.

[0051] The baking equipment also includes temperature detection modules, which are located inside the housing 1. These modules are used to detect the temperature of the conveyor rollers 2. Preferably, there are eight temperature detection modules, each corresponding to one of the conveyor rollers 2, and each module detects the temperature of its respective roller. Specifically, when a temperature increase is detected in the conveyor roller 2, the rotational speed of the roller is adjusted to maintain the tension on the electrode sheet 4 to be dried within a reasonable range. The temperature detection modules are preferably temperature sensors.

[0052] It should be noted that the setting of a temperature detection module is not mandatory. Those skilled in the art can choose whether to set a temperature detection module and the specific structure of the temperature detection module based on the specific application scenario. Of course, it is also possible not to set a temperature detection module.

[0053] It should be noted that the configuration of the drive components described above is not fixed, and those skilled in the art can choose the specific structure of the drive components based on the specific application scenario. For example, the drive components may also include drive motors and gearboxes. Specifically, the drive components consist of four drive motors connected to gearboxes, and one gearbox connected to two adjacent conveyor rollers 2 in the belt conveying direction of the electrode sheet 4 to be dried. This allows one drive motor to drive two conveyor rollers 2 to rotate, and when the speed of the drive motor changes, the speed of the two driven conveyor rollers 2 also changes. The two conveyor rollers 2 driven by the same drive motor can operate at the same speed or with a fixed speed difference.

[0054] It should also be noted that the setting of the drive motor is not necessary. Those skilled in the art can also use other methods to drive the conveyor roller 2 to rotate, such as a pneumatic motor.

[0055] Two guide rollers 3 are disposed inside the housing 1. The two guide rollers 3 are located near the electrode inlet 12 and the electrode outlet 13, respectively. The guide rollers 3 are in contact with the electrode 4 to be dried and are configured to change the conveyor direction of the electrode 4 to be dried. Thus, after the electrode 4 to be dried enters the housing 1, it first passes through the guide rollers 3, allowing the electrode 4 to pass through in a set direction. Before the electrode 4 to be dried exits the housing 1, it finally passes through the other guide roller 3, allowing the electrode 4 to pass through the electrode outlet 13 in a set direction.

[0056] It should be noted that the setting of the guide roller 3 is not mandatory. Technicians in the field can choose whether to set the guide roller 3 based on the specific application scenario. Of course, the guide roller 3 can also be omitted, and when the electrode enters the housing 1, it directly contacts the conveyor roller 2.

[0057] In use, a winding device and an unwinding device are respectively installed outside the electrode inlet 12 and electrode outlet 13 of the housing 1. The electrode 4 to be dried is placed on the unwinding device. After the electrode 4 on the unwinding device is dried by the baking equipment, the winding device winds up the dried electrode. The winding device can also drag the dried electrode to maintain the tension of the electrode itself. The winding device, the unwinding device, and static friction work together, and the diameter of the conveyor roller 2 gradually increases along the belt direction, so that the tension of the electrode 4 to be dried at different positions in the housing 1 gradually increases with the belt direction, avoiding wrinkling and loosening caused by electrode heating and elongation, and reducing the risk of belt abnormalities.

[0058] It should be noted that the specific structures of the unwinding and rewinding devices are existing technologies and will not be described in detail here. The installation of unwinding and rewinding devices is not mandatory; those skilled in the art can choose whether to install them and their specific structures based on the specific application scenario. For example, an unwinding device may be omitted, and the electrode can be directly fed into the baking equipment after production. Similarly, a rewinding device may be omitted, and the electrode can be directly fed into the next process after drying.

[0059] The following describes possible usage methods of the baking equipment during use. Those skilled in the art will understand that the methods described below are merely illustrative and not intended to limit the scope of protection of this application.

[0060] The electrode sheet 4 to be dried is unwound from the unwinding device and enters the housing 1 through the electrode inlet 12. After passing through the guide roller 3, it successively passes over the conveyor roller 2, passes through another guide roller 3, and exits the housing 1 from the electrode outlet 13, where it is wound onto the winding device. During the drying process of the electrode sheet 4, the rotational speed of the subsequent conveyor roller 2 is greater than that of the preceding conveyor roller 2 along the belt travel direction of the electrode sheet 4. After the electrode sheet 4 enters the housing 1, it expands due to heat, and the diameter of the conveyor roller 2 gradually increases along the belt travel direction of the electrode sheet 4. Therefore, even if the electrode sheet 4 expands, it can still contact the conveyor roller 2 and maintain tension. Simultaneously, even if the amount of expansion of the electrode sheet 4 changes, the tension changes caused by the expansion can be balanced in a timely manner by adjusting the speed of the drive motor. This prevents uncontrolled tension of the electrode sheet within the housing 1 and reduces the risk of abnormal belt travel.

[0061] Those skilled in the art will understand that although some embodiments described herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this application and form different embodiments. For example, any of the claimed embodiments in the claims of this application can be used in any combination.

[0062] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
