Description

Technical Field

[0001] This utility model relates to the field of lithium battery separator technology, and in particular to a bidirectional heat setting device for lithium battery separators. Background Technology

[0002] The separator in a lithium-ion battery is a crucial component. It's a porous thin-film material that acts as a barrier between the positive and negative electrodes, preventing internal short circuits. Simultaneously, it must allow for rapid ion flow, ensuring the fast transport of lithium ions between the positive and negative electrodes during charging and discharging. Therefore, the battery separator holds a very important position in battery manufacturing materials and is often referred to as the "third electrode" of the battery. In current technology, lithium batteries are typically heat-set in a unidirectional manner, which is generally ineffective, and the direct discharge of high-temperature exhaust gases generated during the heat-setting process wastes resources.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a bidirectional heat-setting device for lithium battery separators, comprising: a housing 1, with mounting grooves 2 at both ends of the housing 1, a drive assembly 3 at the top of the inner wall of the mounting groove 2, a drive assembly 4 at the bottom of the inner wall of the mounting groove 2, heating assemblies 5 fixedly installed on both sides of the housing 1, a pipe 6 fixedly installed at the output end of the heating assembly 5, an air pump 7 fixedly installed at the other end of the pipe 6, an output end of the air pump 7 fixedly installed on the surface of the housing 1, a flow divider 8 fixedly installed at the output end of the air pump 7, air outlets 9 evenly installed on the surface of the flow divider 8, and an exhaust port 12 installed on the top of the housing 1.

[0025] Specifically: When the device is first used, the diaphragm is fed into the housing 1 by activating the drive assembly 3 and drive assembly 4 installed on the inner wall of the mounting groove 2 at one end of the housing 1. The heating assembly 5 is connected to a steam source (it should be noted that the steam source of this invention comes from the diaphragm production line (the steam source is usually after the stretching process on the diaphragm production line) to heat the steam through the heating pipe inside the heating assembly 5. The air pump 7 is activated to deliver the hot steam through pipe 6 to the inside of the distribution plate 8. After being divided inside the distribution plate 8, the steam flows through the heating pipe installed on the surface of the distribution plate 8. Multiple air outlets 9 discharge hot steam evenly into the device, where it heats and shapes the diaphragm. The shaped diaphragm is then conveyed out of the device through drive assembly 3 and drive assembly 4 located on the inner wall of the groove 2 at the other end of the housing 1. The hot steam is discharged through the exhaust port 12 installed on the top of the housing 1. Heating assembly 5, pipe 6, and air pump 7 are installed on both sides of the housing 1. Heating assembly 5 contains heating tubes, allowing the device to heat-shape the diaphragm from two directions during use, resulting in better diaphragm shaping and a more complete device.

[0026] In one embodiment, drive assembly 3 includes a motor 301, one side of which is fixedly installed on one end of the inner wall of the mounting groove 2. A rotating rod 302 is fixedly installed on the output end of the motor 301. A drive roller 303 is sleeved on the surface of the rotating rod 302. The other end of the rotating rod 302 is installed on the other end of the inner wall of the mounting groove 2 via a bearing. Drive assembly 4 includes a motor 401, one side of which is fixedly installed on one end of the inner wall of the mounting groove 2. A rotating rod 402 is fixedly installed on the output end of the motor 401. A drive roller 403 is sleeved on the surface of the rotating rod 402. The other end of the rotating rod 402 is installed on the other end of the inner wall of the mounting groove 2 via a bearing.

[0027] Specifically: By starting motor 301 and motor 401, rotating rod 302 and rotating rod 402 rotate in opposite directions, causing drive roller 303 and drive roller 403 to rotate in opposite directions, and the diaphragm is conveyed between drive roller 303 and drive roller 403, making the device more complete.

[0028] In one embodiment, a limiting plate 11 is fixedly installed on the inner wall of one end of the housing 1. There are two limiting plates 11, and the two limiting plates 11 form a V-shape.

[0029] Specifically: By fixing two limiting plates 11 on the inner wall of one end of the housing 1, when the diaphragm is conveyed into the device through the drive roller 303 and the drive roller 403, the diaphragm enters the device through the space between the two limiting plates 11. The diaphragm is restricted by the two limiting plates 11 when entering the device, so that the diaphragm can enter the device better and the device is more perfect.

[0030] In one embodiment, fixing blocks 10 are fixedly installed at the four corners of one side of the diverter plate 8, and the other end of the fixing blocks 10 is installed on the inner wall of the housing 1.

[0031] Specifically: The fixing blocks 10, which are fixedly installed at the four corners of one side of the diverter plate 8, are installed on the inner wall of the housing 1, so that the diverter plate 8 can be stably installed on the inner wall of the housing 1, making the device more complete.

[0032] In one embodiment, a second pipe 13 is installed on the inner wall of the exhaust port 12, and a waste heat furnace 14 is installed at the other end of the second pipe 13. A filter block 15 is installed on the surface of the waste heat furnace 14, and a Y-shaped tube 16 is fixedly installed at the other end of the filter block 15. The other end of the Y-shaped tube 16 is installed on one side of the heating assembly 5.

[0033] Specifically: the used steam is discharged through the exhaust port 12 and enters the interior of the second pipe 13, and then enters the interior of the waste heat furnace 14. Inside the waste heat furnace 14, the waste gas exchanges heat with water, turning the water into steam. The generated steam is filtered through the filter block 15 and then enters the interior of the Y-shaped pipe 16. It is then transported to the heating component 5 through the Y-shaped pipe 16, so that the used hot steam can be recycled, reducing resource waste and making the device more perfect.

[0034] In one embodiment, an observation port 17 is provided at one end of the housing 1, and a transparent plate 18 is installed on the inner wall of the observation port 17.

[0035] Specifically: A transparent plate 18 is installed on the inner wall of the observation port 17 opened at one end of the box body 1, so that the internal situation can be seen through the transparent plate 18 during the thermoforming process of the diaphragm, making the device more perfect.

[0036] Working Principle: When the device is first used, the diaphragm is placed between drive roller 303 and drive roller 403. Starting motors 301 and 401 at one end of housing 1 drives rotating rods 302 and 402 to rotate in opposite directions, causing drive rollers 303 and 403 to convey the diaphragm into housing 1. Heating components 5, installed on both sides of housing 1, are activated, allowing hot steam to enter the corresponding air pump 7 through pipe 6. Air pump 7 then delivers the hot steam to the corresponding distribution plate 8. Inside the distribution plate 8, the steam is divided and discharged through multiple outlets 9 on its surface, ensuring even discharge from both directions. The steam then enters the device to heat and shape the diaphragm. The diaphragm is conveyed out of the device through drive assembly 3 and drive assembly 4 at the other end of the housing 1, so that the diaphragm is thermoformed in two directions during use, resulting in better diaphragm forming and a more complete device. During use, the hot steam is discharged through the exhaust port 12 installed on the top of the housing 1, enters the interior of pipe 13, and then enters the interior of waste heat furnace 14. Inside the waste heat furnace 14, the waste steam exchanges heat with the water inside, turning the water into steam. The generated steam is filtered through filter block 15 and then enters the Y-shaped pipe 16. It is then transported to heating assembly 5 through Y-shaped pipe 16 for heating and use by the device. This allows the hot steam to be recycled, reducing resource waste and making the device more complete.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
