[0043] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0044] In the manufacturing process of lithium batteries, drying is an important step to ensure that battery components are dry, prevent chemical short circuits, and improve battery performance. Existing lithium battery drying equipment mostly uses manual operation to load and unload battery components. Due to the high temperature environment involved in the drying process, manual operation is not only limited in efficiency, but also poses a potential safety risk of burns to operators. In addition, the repetitiveness and tediousness of manual operation can easily lead to operational errors, affecting the consistency and reliability of drying quality.

[0045] High temperature environments pose a direct threat to the safety of operators. When manually loading and unloading battery components, improper operation or inadvertent contact with heating elements may cause burns. This risk is particularly prominent on production lines because operators need to work frequently near high-temperature equipment. Therefore, improving the automation level of drying equipment and reducing the need for direct manual contact with high-temperature components are of great significance to reducing work-related accidents and improving production safety.

[0046] Based on the above content, please refer to the attached manual Figure 1 The utility model provides a lithium battery drying device which aims to significantly improve the efficiency and safety of the drying process through automation technology.

[0047] In one embodiment, the reference specification Figure 1The utility model provides a lithium battery drying device, including a drying body 1, a carrying body 2, a driving module, and a control module. The drying body 1 performs efficient drying. The drying body 1 has a accommodating cavity 100, and the accommodating cavity 100 is used to receive the carrying body 2. The carrying body 2 is equipped with a lithium battery and is designed as a ventilated structure so that hot air flows inside it to evenly dry the lithium battery.

[0048] The driving module is integrated on the carrier body 2 and is responsible for realizing the movement of the carrier body 2 inside the drying body 1, the movement of the carrier body 2 into or out of the accommodating cavity 100 of the drying body 1, and the movement of the carrier body 2 on the working ground.

[0049] Furthermore, the driving module is connected to the control module, and the driving mode of the driving module is automatically adjusted according to a preset program or real-time feedback. It can not only control the positioning and movement of the supporting body 2 in the accommodating cavity 100 of the drying body 1, but also realize the natural docking between the supporting body 2 and the accommodating cavity 100, thereby completing the automatic loading and unloading of lithium batteries without human intervention.

[0050] In this embodiment, the control module can be integrated with an intelligent temperature control system to automatically adjust the drying temperature and time according to the type and drying status of the lithium battery; the ventilated structure setting on the supporting body 2 can also be customized according to the size and shape of the lithium battery to meet the drying requirements of different models of lithium batteries.

[0051] In addition, based on the above content, as shown in the figure, the drying body 1 needs to take into account the needs of automated entry and exit, and the opening of the accommodating cavity 100 is set as a lateral opening. At the same time, the size of the lateral opening is larger than the size of the supporting body 2, providing sufficient space to avoid collision or scratches during entry and exit, so that the supporting body 2 can smoothly enter and exit the accommodating cavity 100 without the need for drastic movement or change of direction, greatly improving the efficiency of loading and unloading lithium batteries.

[0052] In addition, since the opening is located on the side, it provides operators with a more intuitive view and a more accessible working area, reducing the risks that may be encountered when loading and unloading lithium batteries. At the same time, the design of the side opening simplifies the mechanical structure, reduces the space occupied by the equipment, and makes the entire drying device more compact and practical.

[0053] The driving module in the above content is arranged at the bottom of the carrier body 2, wherein, Figure 4As shown, the driving module includes at least one motor 31, which converts the rotational motion into linear or curved motion through a connected motion mechanism, which can be a gear, a slide rail, a belt or other transmission mechanism, to achieve smooth displacement of the supporting body 2, ensuring that the supporting body 2 can automatically enter and exit the accommodating cavity 100 of the drying body 1 through the side opening according to a preset program.

[0054] Furthermore, the movement mechanism includes two parallel tracks 32. The two tracks 32 are symmetrically distributed at the bottom of the bearing body 2, increasing the contact area with the bottom wall of the drying body 1, thereby providing greater friction and bearing capacity, ensuring the stability and reliability of the bearing body 2 during movement.

[0055] Moreover, if Figure 1 As shown, the bottom wall of the drying body 1 is provided with a guide member 4, and the guide member 4 and the drying body 1 together form two vacant parts adapted to the crawler 32. When the bearing body 2 enters or leaves the drying body 1, the crawler 32 can be smoothly embedded in the vacant part, providing a stable guide for the crawler 32, and forming a certain limit effect to prevent the bearing body 2 from deflecting or tilting during the movement. On the other hand, the surface of the guide member 4 can be designed as a smooth structure to reduce the friction of the crawler 32 when embedded, ensuring that the bearing body 2 smoothly enters and exits the accommodating cavity 100 along a predetermined trajectory.

[0056] In one embodiment, Figure 1 and Figure 2 As shown, the lithium battery drying device further includes a guide portion 5, one end of which is firmly abutted against the side wall of the drying body 1 to form a fixed and reliable guide reference.

[0057] Specifically, the upper surface of the guide portion 5 is designed to be an inclined slope 50, one end of which is connected to the interior of the accommodating chamber 100, providing an entry path for the supporting body 2; the other end is connected to the working ground, ensuring that the supporting body 2 can safely reach the working ground after exiting the accommodating chamber 100. In other words, the supporting body 2 can smoothly enter or exit the accommodating chamber 100 along the slope under the combined action of gravity and the power of the driving module.

[0058] It can be understood that the design of the guide portion 5 optimizes the in and out process of the load-bearing body 2, and improves the operating efficiency and reliability of the entire drying device by reducing the friction and resistance during the movement. The angle and length of the inclined slope 50 can be adjusted according to specific circumstances to adapt to the size and weight of the load-bearing body 2, while ensuring stability under different operating conditions.

[0059] In addition, the guide portion 5 may be made of different materials and surface treatment processes, such as wear-resistant coating or anti-slip material, to resist wear and tear caused by frequent use and ensure good performance in various working environments.

[0060] In one embodiment, based on the above embodiments, Figure 3 As shown, the carrier body 2 includes a bottom support portion 21 and a battery bracket 22 . The bottom support portion 21 serves as the basis of the carrier body 2 and provides a stable supporting platform. The battery bracket 22 is disposed on the upper surface of the bottom support portion 21 .

[0061] Specifically, the interior of the battery bracket 22 adopts a hollow design to form a space specifically for accommodating lithium batteries, and ensures that hot air can flow freely inside the battery bracket 22 during the drying process, achieving uniform heating of the lithium batteries, thereby improving drying efficiency and quality.

[0062] In this embodiment, the combination of the bottom bracket 21 and the battery bracket 22 needs to ensure the stability of the battery bracket 22 and facilitate installation and removal. The battery bracket 22 can be fixed or detachable to meet different production requirements and maintenance convenience. In the fixed design, the battery bracket 22 is tightly combined with the bottom bracket 21 by welding, bolting or other fixing methods; in the detachable design, the battery bracket 22 can be easily installed or removed through a quick release mechanism, which is convenient for replacement or cleaning.

[0063] Furthermore, the bottom bracket 21 can integrate the supporting function of the bearing body 2 and the installation requirements of the drive module. Specifically, the bottom bracket 21 is provided with an installation space with an opening facing downward, which is used to accommodate the drive module, ensuring stable installation and convenient maintenance of the drive module.

[0064] Among them, the bottom of the bottom support part 21 is higher than the bottom of the moving mechanism. Since the bottom of the bottom support part 21 does not directly contact the ground, the possibility of wear caused by friction between the bottom support part 21 and the ground during the operation of the equipment is eliminated, thereby extending the service life of the bottom support part 21.

[0065] In addition, an inspection port is provided on the side surface of the bottom bracket 21. The inspection port is connected to the installation space inside the bottom bracket 21, providing a channel for operators to maintain the drive module, making the inspection, maintenance or replacement of the drive module easier and faster.

[0066] Moreover, if Figure 1 As shown, the inspection port is provided with a movable inspection door 211. The inspection door 211 can conveniently open or close the inspection port, ensuring that the inspection port can remain closed when maintenance is not required, preventing dust, moisture or other impurities from entering the installation space, and protecting the drive module from environmental factors.

[0067] At the same time, a simple and reliable locking mechanism can be set on the inspection door 211 to ensure that it can be stably fixed in the open position when opened, and can tightly seal the inspection port when closed, thereby improving the convenience of using the inspection port and enhancing the sealing and protection performance of the entire bottom bracket 21. On the other hand, the size and position of the inspection port can be adjusted according to the size of the bottom bracket 21 and the installation position of the drive module, ensuring that the inspection port provides sufficient operating space for the drive module, while also ensuring the overall structural strength and stability of the bottom bracket 21.

[0068] Based on the above, a positioning member 212 is provided on the upper surface of the bottom support portion 21 , and the bottom of the battery bracket 22 is engaged with the positioning member 212 to prevent deviation or misalignment during the drying process.

[0069] It is understandable that the design of the positioning member 212 needs to correspond to the size and shape of the battery bracket 22, as well as the dynamic conditions that may be encountered during the drying process. The battery bracket 22 and the positioning member 212 can be mechanically engaged, snapped or locked to achieve a stable positioning of the battery bracket 22, ensuring the horizontal and vertical stability of the battery bracket 22 on the bottom bracket 21, simplifying the installation process, and improving the reliability of the overall structure.

[0070] In addition, additional auxiliary positioning features, such as protrusions, grooves or positioning pins, can be designed on the positioning member 212. These features cooperate with the corresponding structures on the battery bracket 22 to provide double protection and ensure that the battery bracket 22 can maintain the correct position under any circumstances.

[0071] In this embodiment, the positioning piece 212 provided on the bottom support portion 21 adopts a simple and effective annular structure, which matches the bottom of the battery bracket 22 to ensure that the bottom of the battery bracket 22 can be accurately embedded in the predetermined position of the bottom support portion 21. Moreover, its continuous annular design also helps to evenly distribute the force on the battery bracket 22 and reduce local stress concentration, thereby improving the durability and reliability of the entire structure.

[0072] In another embodiment, the number of the battery brackets 22 in the above embodiment is at least two, and each battery bracket 22 is designed to be a hollow structure to provide an independent lithium battery placement space. These battery brackets 22 are stacked in the vertical direction, so that more lithium batteries can be dried simultaneously per unit time, significantly improving the drying efficiency and production capacity.

[0073] Furthermore, a limiting structure is provided between adjacent battery brackets 22. Figure 3The upper battery bracket 22 has a limiting end 221 at the bottom, and the lower battery bracket 22 has a limiting hole 220 at the top, or vice versa (not shown in the figure), the upper battery bracket 22 has a limiting hole 220 at the bottom, and the lower battery bracket 22 has a corresponding limiting end 221 at the top, so that multiple battery brackets 22 form a firm integrated structure when stacked.

[0074] Specifically, when the battery brackets 22 are stacked, the limiting holes 220 and the limiting ends 221 are precisely engaged, providing a mechanical locking effect, effectively preventing relative movement or misalignment between the layers of battery brackets 22 during the drying process. This engaging structure not only ensures the vertical stability of the battery brackets 22, but also can absorb and alleviate deformation caused by thermal expansion or other external forces to a certain extent.

[0075] In one embodiment, different from the above embodiment, as Figure 1 and Figure 3 As shown, the side wall of the battery bracket 22 is provided with a bracket door plate 222 and at least one mesh panel 223, and these two components are respectively arranged on different side walls of the battery bracket 22 to achieve specific functions.

[0076] The mesh panels 223 are provided to achieve effective air flow between the accommodating chamber 100 and the inside of the battery tray 22. Through these mesh panels 223, hot air can flow evenly during the drying process, ensuring that the lithium batteries are fully and uniformly dried inside the battery tray 22. At the same time, the mesh panels 223 optimize the air flow path, thereby shortening the drying cycle and improving energy efficiency.

[0077] The bracket door panel 222 can be opened and closed relative to the battery bracket 22. The operator can easily load and unload the battery by opening the bracket door panel 222. In the closed state, the bracket door panel 222 not only protects the lithium battery from the external environment, but also prevents the lithium battery from falling off during the drying process or the moving process, thereby ensuring the safety of the operation and the integrity of the lithium battery.

[0078] Furthermore, if Figure 5 As shown, at least one hot air box 6 is provided on the drying body 1, and is connected to the accommodating cavity 100 through an internal channel or pipeline. The hot air box 6 is used to input hot air into the accommodating cavity 100, providing uniform and continuous heat energy for the lithium battery, and realizing efficient drying operation.

[0079] Specifically, the hot air box 6 is generally equipped with a heating element inside, such as an electric heater or a heat exchanger, and these elements can heat the incoming air to a predetermined temperature quickly. In addition, the hot air box 6 can also include a fan or other air circulation equipment to assist the delivery of the hot air.

[0080] When there are multiple hot air boxes 6 (not shown in the drawings), each hot air box 6 is connected to the accommodating chamber 100, and can independently input hot air to different areas of the accommodating chamber 100, so that the entire drying process can achieve regional hot air supply according to the placement and drying requirements of the lithium batteries. For example, if the lithium batteries are unevenly distributed in the accommodating chamber 100, or some areas require more heat energy to achieve a drying effect, multiple hot air boxes 6 can provide hot air in a targeted manner to ensure the uniformity and consistency of the entire drying process.

[0081] In addition, each hot air box 6 can independently perform temperature adjustment and troubleshooting, simplifying maintenance work. At the same time, the layout of the hot air boxes 6 can be optimized according to the specific structure of the drying body 1 to achieve the best hot air flow path and drying effect.

[0082] In one embodiment, Figure 2 As shown, a cover 11 is provided on the drying body 1, and the cover 11 can be closed or opened relative to the opening of the accommodating cavity 100. When the cover 11 is in the open state, a travel passage is provided so that the carrying body 2 can smoothly enter or exit the accommodating cavity 100. The opening and closing mechanism of the cover 11 can be automated to improve the automation degree of the drying device.

[0083] In addition, the drying body 1 is also provided with an exhaust box 7. The exhaust box 7 is installed on the side wall or top wall of the drying body 1, and the exhaust box 7 is connected to the accommodating cavity 100, and is responsible for discharging moisture or other gases in the accommodating cavity 100 during the drying process to maintain suitable conditions of the drying environment.

[0084] Furthermore, the exhaust box 7 may be equipped with a filter element to remove particulate matter or harmful components in the exhaust gas to reduce the impact on the environment. The exhaust box 7 may also be connected to an external ventilation system or air treatment equipment to achieve centralized processing of the exhaust gas.

[0085] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
