[0001] The utility model relates to the technical field of drying, in particular to a lithium battery drying device. Background Art

[0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as positive / negative electrode material and non-aqueous electrolyte solution. With the development of science and technology, the application of lithium batteries is becoming more and more extensive and the use is becoming more and more frequent. In recent years, the development of lithium batteries has also been greatly improved. Its development has brought great convenience to people's lives directly or indirectly. The drying process in the production and manufacturing process of lithium batteries has very strict control over moisture, because lithium-ion batteries are very sensitive to moisture. Excessive moisture content inside the battery will have a great impact on battery performance and safety. Therefore, in the production and manufacturing process of lithium-ion batteries, they usually need to be dried.

[0003] The patent number CN218270005U in the prior art discloses a lithium battery drying device, which aims to solve the technical problem that the drying equipment in the prior art can evenly dry the outside of the lithium battery, but the handle needs to be manually turned to rotate the lithium battery for drying, which is time-consuming and labor-intensive, and only one lithium battery can be placed for drying, which greatly reduces the efficiency of lithium battery drying. The lithium battery drying device comprises a shell, wherein the outer wall at the bottom of the shell is fixedly connected to a motor, one end of the motor output shaft passes through the shell and is fixedly connected to a rotating disk, the outer wall of the rotating disk is fixedly connected to an equidistant and evenly distributed rectangular plate and is on the same horizontal plane as the rotating disk, one end of the rectangular plate is connected to a circular rod with a bearing, one end of the circular rod passes through the rectangular plate and is fixedly connected to a gear, the other end of the circular rod is fixedly connected to a mesh square box, the inner wall at the bottom of the shell is fixedly connected to an annular rack, the gear is meshed with the annular rack, the outer wall of one side of the shell is fixedly connected to a hot air blower, one end of the hot air blower output shaft is fixedly connected to an air supply box, the outer wall of one side of the air supply box is provided with a plurality of evenly distributed blowing holes, the other side of the shell is provided with an air outlet, one side of the shell is provided with an opening, and the opening hinge is connected to a door panel.

[0004] However, the patents in the prior art have the following disadvantages:

[0006] (2) The patent in the prior art does not dry the lithium battery thoroughly enough during use. When drying the lithium battery, the lithium battery is placed inside the mesh square box, which makes it impossible for the part of the lithium battery that is in direct contact with the mesh square box to be effectively dried. Utility Model Content

[0007] The technical problem to be solved by the utility model is to overcome the above technical defects and provide a lithium battery drying device with a thermal cycle function, energy saving and emission reduction, and the ability to improve the air drying integrity performance of the device.

[0008] In order to solve the above problems, the technical solution of the utility model is: a lithium battery drying device, characterized in that it includes a main body, legs, a top cover, a motor, a heat exchanger, a cavity and a rotating shaft;

[0009] The support leg is fixedly connected to the bottom of the main body, the top cover is located at the top of the main body, the motor is fixedly connected to the right outer side wall of the main body, the heat exchanger is fixedly connected to the middle position of the bottom of the main body, the cavity is opened inside the main body, one end of the rotating shaft penetrates the right side wall of the main body and is rotatably connected to the motor on the right outer side wall of the main body, the other end of the rotating shaft is rotatably connected to the left inner side wall of the main body, and the rotating shaft is in a horizontal position.

[0010] Furthermore, a turntable is fixedly connected to the surface of one end of the rotating shaft close to the left inner wall of the main body. Two turntables are provided, and the other one is symmetrically fixedly connected to the surface of one end of the rotating shaft close to the right inner wall of the main body.

[0011] Furthermore, two groups of clamping mechanisms are symmetrically arranged on the surface of the turntable.

[0012] Furthermore, the clamping mechanism includes a sleeve, an inner cavity, a limit groove, a spring, a limit block, an inner rod, a clamping plate, a cushion layer and an opening, the rear end of the sleeve is fixedly connected to the surface of the turntable, the inner cavity is opened inside the sleeve, the limit groove is opened in the upper and lower side walls of the sleeve, the rear end of the spring is fixedly connected to the surface of the turntable at the rear end of the sleeve, and the rear end of the limit block is fixedly connected to the front end of the spring.

[0013] Furthermore, the rear end of the inner rod is fixedly connected to the front end of the limit block, the opening is opened at the front end of the sleeve, the front end of the inner rod extends outward from the opening, the front end of the inner rod is fixedly connected to a clamping plate, and the cushion layer is fixedly connected to the inner arc surface of the clamping plate.

The high-temperature exhaust gas collected in the main body cavity and the fresh air at normal temperature outside are heat-exchanged in the heat exchanger. The temperature of the fresh air is significantly increased after the heat exchange, which can greatly reduce the energy consumption of heating the fresh air to the temperature of the oven;

[0017] (2) The utility model is provided with a clamping plate structure to solve the problem of incomplete drying of lithium batteries. When in use, because a semicircular notch is provided on one side of the clamping plate and the two clamping plates are arranged opposite to each other, and most lithium batteries are rectangular, the semicircular notch can be used to clamp the lithium battery so that the clamping plate only contacts the edge of the lithium battery to clamp it, rather than directly clamping the two sides of the lithium battery, thereby reducing the contact area between the clamping plate and the lithium battery, thereby avoiding the situation where some parts are in contact with the clamping plate, making it difficult for hot air to pass through and effectively dry them, thereby improving the air-drying performance of the device.

DETAILED DESCRIPTION

[0023] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings, wherein the same parts are represented by the same reference numerals.

[0024] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0026] like Figures 1 to 4 As shown, a lithium battery drying device is characterized in that it includes a main body 1, a leg 2, a top cover 3, a motor 4, a heat exchanger 5, a cavity 6 and a rotating shaft 7; the leg 2 is fixedly connected to the bottom of the main body 1, the top cover 3 is located at the top of the main body 1, the motor 4 is fixedly connected to the right outer side wall of the main body 1, the heat exchanger 5 is fixedly connected to the middle position of the bottom of the main body 1, the cavity 6 is opened inside the main body 1, one end of the rotating shaft 7 penetrates the right side wall of the main body 1, and is rotatably connected to the motor 4 on the right outer side wall of the main body 1, and the other end of the rotating shaft 7 is rotatably connected to the left inner side wall of the main body 1, and the rotating shaft 7 is in a horizontal position.

[0027] like Figure 2 As shown, a turntable 8 is fixedly connected to the surface of one end of the rotating shaft 7 close to the left inner wall of the main body 1. Two turntables 8 are provided, and the other one is symmetrically fixedly connected to the surface of one end of the rotating shaft 7 close to the right inner wall of the main body 1. When in use, the motor 4 drives the two turntables 8 to rotate synchronously through the rotating shaft 7. During the rotation process, on the one hand, it can promote the flow of hot air in the cavity 6 so that the hot air can fill the entire cavity 6. On the other hand, it drives the lithium battery to rotate, so that the lithium battery can fully contact with the hot air in the cavity 6 to achieve the best drying effect.

[0028] like Figure 3 As shown, two groups of clamping mechanisms 9 are symmetrically arranged on the surface of the turntable 8. When in use, the two groups of clamping mechanisms 9 are symmetrically arranged to clamp the lithium battery firmly, so that the lithium battery will not become loose during the rotation of the turntable 8.

[0029] like Figure 4As shown, the clamping mechanism 9 includes a sleeve 901, an inner cavity 902, a limiting groove 903, a spring 904, a limiting block 905, an inner rod 906, a clamping plate 907, a cushion layer 908 and an opening 909. The rear end of the sleeve 901 is fixedly connected to the surface of the turntable 8, the inner cavity 902 is opened inside the sleeve 901, the limiting groove 903 is opened in the upper and lower side walls of the sleeve 901, the rear end of the spring 904 is fixedly connected to the surface of the turntable 8 at the rear end of the sleeve 901, and the rear end of the limiting block 905 is fixedly connected to the front end of the spring 904. When in use, the spring 904 can be extended and retracted to drive the inner rod 906 to slide back and forth along the limiting groove 903 through the limiting block 905, so that the inner rod 906 extends outward at different lengths, thereby achieving a clamping effect for lithium batteries of different sizes.

[0030] like Figure 4 As shown, the rear end of the inner rod 906 is fixedly connected to the front end of the limit block 905, the opening 909 is opened at the front end of the sleeve 901, and the front end of the inner rod 906 extends outward from the opening 909. The front end of the inner rod 906 is fixedly connected with a clamping plate 907, and the cushion layer 908 is fixedly connected to the inner arc surface of the clamping plate 907. When in use, because one side of the clamping plate 907 is set as a semicircular notch, and most lithium batteries are rectangular, the semicircular notch is used to clamp the lithium battery so that the clamping plate 907 can only contact the edge of the lithium battery. The clamping plate 907 contacts and clamps the lithium battery instead of directly clamping the two sides of the lithium battery, thereby reducing the contact area between the clamping plate 907 and the lithium battery, thereby avoiding the situation where some positions are in contact with the clamping plate 907, resulting in difficulty for hot air flow to pass through and effectively dry the lithium battery, thereby improving the air-drying integrity performance of the device. At the same time, the cushion layer 107 on the inner arc surface of the clamping plate 907 is made of sponge material. The high wear resistance and high softness of the sponge material can be used to avoid the situation where the clamping force of the clamping plate 907 is too large to damage the lithium battery, thereby improving the practicability of the device.

[0031] like Figures 1 to 4 As shown, the heat exchanger 5 includes an air inlet 501, an exhaust gas delivery pipe 502 and a hot air delivery pipe 503. The air inlet 501 is opened on the side of the heat exchanger 5, one end of the exhaust gas delivery pipe 502 is connected to the side of the heat exchanger 5, and the other end is connected to the cavity 6 of the main body 1 on the same side. One end of the hot air delivery pipe 503 is connected to the other side of the heat exchanger 5, and the other end is connected to the cavity 6 of the main body 1 on the same side. When in use, high-temperature exhaust gas will be generated during drying. The high-temperature exhaust gas collected from the cavity 6 of the main body 1 through the exhaust gas delivery pipe 502 and the external normal temperature fresh air entering through the air inlet 501 exchange heat in the heat exchanger 5. The temperature of the fresh air will be significantly increased after the heat exchange, and will be input into the cavity 6 of the main body 1 through the hot air delivery pipe 503. In this way, the energy consumption of heating the fresh air to the temperature required for drying can be greatly reduced.

[0032] In specific use, the top cover 3 is opened, the motor 4 is started to drive the rotating shaft 7 to rotate, and then the lithium batteries to be dried are clamped and fixed in turn through the clamping mechanism 9 on the turntable 8. After fixing, the top cover is covered, the heat exchanger 5 is started, and the motor 4 drives the two turntables 8 to rotate synchronously through the rotating shaft 7, thereby driving the lithium battery to rotate in the cavity 6 through the clamping mechanism 9. During the rotation process, on the one hand, it can promote the flow of hot air in the cavity 6 so that the hot air can fill the entire cavity 6, and on the other hand, it drives the lithium battery to rotate, so that the lithium battery can fully contact with the hot air in the cavity 6 to achieve the best drying effect. After the drying is completed, the top cover 3 is removed, and after the temperature in the cavity 6 drops, the dried lithium batteries are removed from the clamping mechanism 9 in turn.

[0033] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
