Description

Technical Field

[0001] This utility model relates to the field of battery drying oven technology, and in particular to a battery drying oven with optimized internal gradient placement and heating method. Background Technology

[0002] In the battery manufacturing process, drying the battery body is a key step to ensure its electrochemical performance and structural stability. The drying effect directly affects the finished product qualification rate and service life of the battery.

[0003] However, in existing technologies, traditional drying ovens lack a scientific battery placement structure. They often use a single-layer flat or disorderly stacking method to place the batteries, resulting in uneven distribution of hot airflow in the oven cavity. Some batteries cannot fully contact the hot airflow, leading to incomplete drying or low drying efficiency. Furthermore, the hot airflow generated by heating lacks a directional guidance and circulation mechanism, relying only on natural convection or simple fan disturbance. Temperature gradient differences are easily formed in the oven cavity, resulting in inconsistent drying degrees of batteries in different locations, affecting product quality stability. Utility Model Content

[0004] The purpose of this invention is to solve the technical problems of low efficiency and uneven heating of the battery body in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a battery drying oven with optimized internal gradient placement and heating method: including a shell and a cavity, and further including: The battery assembly to be processed is embedded inside the cavity, including multiple placement boxes, and multiple battery bodies are embedded inside the multiple placement boxes; Multiple heating elements are provided and fixed to the inner wall surface of the cavity. The circulation component is fixed to the upper surface of the cavity.

[0006] In a preferred embodiment, the battery assembly to be processed further includes: The display shelf is embedded inside the cavity; Several of the display boxes are located inside the display rack.

[0007] The technical effects of adopting the above-mentioned further solution are: it facilitates the centralized storage and layered arrangement of the placement box, provides stable support for the battery body, and at the same time, the structural design of the placement rack can accurately realize the gradient placement of the battery body, ensuring that each layer of battery body can fully contact the hot airflow.

[0008] In a preferred embodiment, four rollers are fixedly connected to the lower surface of the display rack.

[0009] The technical effect of adopting the above-mentioned further solution is that the four rollers allow the placement frame to move flexibly, making it easy to send the battery components to be processed into or out of the cavity as a whole, reducing the labor intensity of loading and unloading operations and improving work efficiency.

[0010] In a preferred embodiment, two limiting slide rails are provided below the four rollers, and the lower surfaces of the two limiting slide rails are fixed to the inner wall surface of the cavity.

[0011] The technical effect of adopting the above-mentioned further solution is that the limiting slide rail guides the movement of the roller, ensuring that the placement frame smoothly enters and exits the cavity along a fixed trajectory, avoiding deviation during movement, and improving positioning accuracy.

[0012] In a preferred embodiment, one end of each of the two limiting slide rails is fixedly connected to a limiting gate.

[0013] The technical effect of adopting the above-mentioned further solution is that the limit gate accurately restricts the movement endpoint of the placement rack, prevents it from sliding excessively into the cavity, ensures that the placement rack is in the preset working position in the cavity, and guarantees the stability of the drying process.

[0014] In a preferred embodiment, the loop component includes: There are two axial flow fans, which are fixed on the upper surface of the cavity.

[0015] The technical effect of adopting the above-mentioned further solution is that the operation of the axial flow fan accelerates the air flow in the cavity, promotes the circulation of hot air, effectively eliminates local temperature differences, and improves the uniformity of battery drying.

[0016] In a preferred embodiment, the circulation component further includes: The drainage hood is fixed to the outer surface of the cavity, with one end connected to the output end of two axial flow fans and the other end connected to the upper surface of the cavity.

[0017] The technical effect of adopting the above-mentioned further solution is that the duct guides the airflow generated by the axial flow fan in a directional manner, so that the airflow returns to the cavity in a preset path, reducing airflow loss, enhancing heat circulation efficiency, and further optimizing temperature distribution.

[0018] In one preferred embodiment, a protective plate is fixedly connected to the upper surface of one of the heating tubes, and the upper surface of the protective plate has a plurality of through holes at equal intervals.

[0019] The technical effect of adopting the above-mentioned further solution is that the protective plate prevents the battery body or the placement box from directly contacting the heating tube, avoiding damage caused by local overheating. At the same time, the through hole can ensure that the heat is evenly diffused into the cavity, taking into account both protection and heating uniformity.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In use, the battery cells to be processed are first embedded one by one into the placement box. Then, the placement boxes are placed in layers on the placement rack according to requirements. The multi-layer structure of the placement rack achieves gradient placement of the battery cells inside, ensuring that each layer is fully in contact with the hot airflow. The placement rack is pushed so that its bottom rollers slide along the limit rail. After it is in place, the limit gate is closed to complete the positioning in the cavity. Then, the outer shell is closed and the heating tube is turned on to release heat into the cavity, so that the gradient-placed battery cells are dried and the drying efficiency is improved.

[0021] When using this invention, after closing the outer shell, the heating tube is activated, and the heat is evenly diffused into the cavity through the through holes on the protective plate. The protective plate can prevent the battery body or the placement box from directly contacting the heating tube and causing local overheating. At the same time, the axial flow fan is activated, and the airflow is directionally guided back into the cavity through the diversion cover to form an efficient heat circulation, so that the battery body is evenly heated.

[0024] 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.

[0025] Example 1 Please see Figures 1-6 This embodiment provides a battery drying oven with optimized internal gradient placement and heating method, the specific idea of ​​which is as follows: As one specific implementation, it includes a housing 1 and a cavity 2, and further includes: The battery assembly to be processed is embedded inside the cavity 2, including multiple placement boxes 6, and multiple battery bodies 7 are embedded inside the multiple placement boxes 6; Multiple heating tubes 3 are provided and fixed to the inner wall surface of the cavity 2; The circulation component is fixed to the upper surface of cavity 2.

[0026] As one specific implementation method, the battery assembly to be processed also includes: The display shelf 5 is embedded inside the cavity 2; Among them, multiple placement boxes 6 are located inside the placement rack 5.

[0027] In this embodiment, the specific type of the battery assembly to be processed can be various, and this application does not limit it. In an optional embodiment, as an example of a battery assembly to be processed, the battery assembly includes: a placement rack 5, a placement box 6, and a battery body 7, the specific quantity of each component as follows: Figure 5 and Figure 6 As shown, the settings are as follows: In this embodiment, a display rack 5 is provided, which is embedded inside the cavity 2 and has multiple shelves for placing the display box 6.

[0028] To support the battery body 7 and prevent it from shifting during the drying process, a flexible buffer layer can also be provided on the inner wall of the placement box 6 to prevent damage caused by hard contact between the battery body 7 and the box.

[0029] In one specific implementation, four rollers 10 are fixedly connected to the lower surface of the display rack 5, and two limiting slide rails 12 are provided below the four rollers 10. The lower surface of the two limiting slide rails 12 is fixed to the inner wall surface of the cavity 2, and a limit gate 11 is fixedly connected to one end of each of the two limiting slide rails 12.

[0030] In this embodiment, during use, the battery bodies 7 to be processed are first embedded one by one into the placement box 6. Then, the placement box 6 containing the battery bodies 7 is placed layer by layer on the shelf of the placement rack 5 as required. The multi-layer structure of the placement rack 5 realizes the internal gradient placement of the battery bodies 7, ensuring that each layer of battery bodies 7 can fully contact the hot airflow. Next, the placement rack 5 is pushed so that the four rollers 10 at its bottom slide along the two limit slide rails 12. After reaching the designated position, the limit gate 11 is closed to complete the positioning of the placement rack 5 inside the cavity 2. Then, the outer shell 1 is closed, and multiple heating tubes 3 are started. The heating tubes 3 release heat into the internal space of the cavity 2. The circulation component drives the airflow inside the cavity 2, and finally the gradient-placed battery bodies 7 complete the drying operation in a stable and uniform temperature environment. The heating is divided into two stages. In the first heating stage, that is, the temperature rise stage, the heating tubes 3 located at the bottom, sides and rear of the furnace will start working. Once the temperature of the battery body 7 inside the furnace reaches the specified temperature, the heating phase ends and the heat preservation phase begins. During the heat preservation phase, the top heating tube 3 generates heat, while the bottom heating tube 3 provides auxiliary heating, and the other heating tubes 3 stop operating.

[0031] Example 2 like Figure 1 , Figure 2 and Figure 4 As shown, based on Embodiment 1, this embodiment also provides a circulation component, which is fixed on the upper surface of the cavity 2. Two axial flow fans 4 are provided and fixed on the upper surface of the cavity 2. The flow hood 9 is fixed on the outer surface of the cavity 2, with one end connected to the output end of the two axial flow fans 4 and the other end connected to the upper surface of the cavity 2.

[0032] As one specific implementation, the circulation component includes: an axial flow fan 4, which is fixed to the upper surface of the cavity 2 by multiple bolts to drive the airflow inside the cavity 2; The airflow generated by the axial flow fan 4 is directed back into the cavity 2. The inner wall of the airflow guide shroud 9 is designed with an arc shape to reduce airflow resistance and improve the efficiency of hot airflow circulation.

[0033] In one specific implementation, a protective plate 8 is fixedly connected to the upper surface of one of the heating tubes 3, and multiple through holes are equidistantly opened on the upper surface of the protective plate 8.

[0034] In this embodiment, during use, the heat released by the heating tube 3 is evenly diffused into the cavity 2 through multiple through holes on the protective plate 8. The protective plate 8 can prevent the battery body 7 or the placement box 6 from directly contacting the heating tube 3 and causing local overheating. At the same time, two axial flow fans 4 are started. The airflow generated by the operation of the axial flow fans 4 is guided by the flow guide hood 9 and flows back into the cavity 2, forming an efficient heat circulation, so that the temperature of each area in the cavity 2 is uniform, and finally the battery body 7 is stably dried. Since the axial flow fans 4 assist in blowing and heating throughout the heating stage, the heating in the heat preservation stage can maintain the temperature inside the furnace and can also increase the temperature to a certain extent, which can fully meet the heating requirements.

[0035] In addition, a battery pack may be provided in this application to provide power to the internal components of the heating tube 3 and the axial flow fan 4. The circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.

[0036] Working principle: The battery body 7 is the element to be dried. It is first placed in the placement box 6, which is used to support and limit the battery body 7. Then, it is placed in layers on the placement rack 5 with multi-layer plates to achieve gradient placement. The bottom of the placement rack 5 is fixed with rollers 10, which can slide along the limiting slide rail 12 on the inner wall of the cavity 2. The limiting slide rail 12 plays a guiding role, and the limiting gate 11 at one end is used to abut against the rollers 10 to complete the precise positioning of the placement rack 5. After the outer shell 1 is closed, a closed space is formed. After the multiple heating tubes 3 are activated, heat is released.

[0037] The protective plate 8 above the heating tube 3 has multiple through holes, which not only allows the heat to be evenly distributed, but also prevents the battery body 7 or the placement box 6 from directly contacting the heating tube 3 and causing local overheating. At the same time, the two axial flow fans 4 on the upper surface of the cavity 2 generate airflow, which is guided back into the cavity 2 by the flow guide 9 fixed on the outer surface of the cavity 2.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.

In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
