[0002] During the battery manufacturing process, it is particularly critical to control the moisture content in the battery. The higher the moisture content, the worse the battery cycle performance and the service life will be greatly shortened. Therefore, in order to reduce the moisture content inside the battery, the battery is usually baked before being filled with liquid. The baking devices in the existing technology all use a whole heating plate directly as a heating mechanism, and then the battery is placed on the heating plate for baking. This type of heating mechanism is only compatible with batteries of a small range of sizes. If the size of the battery changes significantly, the old heating plate needs to be removed and a new heating plate needs to be installed before it can be used, which has poor compatibility with battery product replacement.

[0036] Example 1

[0037] like Figure 1-Figure 5As shown, a heating mechanism 1 is provided in the first embodiment of the present invention, and the heating mechanism 1 includes a heating plate 11 and a plurality of heat-conducting plates 12; the heating plate 11 has a heating plane 111, and the heat-conducting plates 12 are detachably connected to the heating plane 111 of the heating plate 11, and a heat-conducting area 120 for supporting the battery 2 is formed on the surface of the plurality of heat-conducting plates 12 away from the heating plane 111 of the heating plate 11.

[0038] Based on this technical solution, a plurality of heat-conducting plates 12 are installed on the heating plane 111 of the heating plate 11 in a detachable connection manner, and a heat-conducting area 120 for supporting the battery 2 is formed on the surface of the heating plane 111 of the heating plate 11 away from the plurality of heat-conducting plates 12. The area of ​​the heat-conducting area 120 can be changed by increasing or decreasing the number of heat-conducting plates 12 on the heating plate 11 and / or changing the arrangement shape between the plurality of heat-conducting plates 12 to adapt to the heating and baking requirements of batteries 2 of different sizes, thereby improving the compatibility when the battery 2 is replaced.

[0039] Multiple heat conducting plates 12 are arranged side by side along the width of the heat conducting plates 12. By adjusting the number and arrangement of the heat conducting plates 12, the area of ​​the heat conducting region 120 can be flexibly adjusted to accommodate the heating and baking requirements of batteries 2 of different sizes. By detachably connecting the heat conducting plates 12 to the heating plate 11 and adopting a layout in which multiple heat conducting plates 12 are arranged side by side, each heat conducting plate 12 can be independently maintained and upgraded. For example, if a heat conducting plate 12 needs to be replaced or repaired, it can be easily removed from the multiple heat conducting plates 12 and replaced with a new one without affecting the normal operation of the other heat conducting plates 12.

[0040] In the first embodiment, there are ten heat conducting plates 12 , which are arranged to form a rectangular heat conducting area 120 .

[0041] Any two adjacent heat conducting plates 12 are in contact with each other. If the two adjacent heat conducting plates 12 are not in contact with each other, there will be a gap between the two adjacent heat conducting plates 12, which will result in the battery 2 corresponding to the gap not being heated by the heat conducting plate 12, affecting the baking quality of the battery 2. Therefore, by adopting a method of any two adjacent heat conducting plates 12 being in contact with each other, there can be no gap between any two adjacent heating plates 11, so that the heat conducting area 120 can fully contact the battery 2 and heat the battery 2, thereby improving the baking quality of the battery 2.

[0042] The heat conducting plate 12 has a first surface 121 that mates with the heating surface 111. The direct contact between the heating surface 111 and the first surface 121 reduces the intermediary layer required for heat transfer between the heating plate 11 and the heat conducting plate 12 support, enabling faster and more direct heat transfer from the heating surface to the heat conducting plate. This direct thermal contact improves heat transfer efficiency and ensures effective heat utilization during the baking process. By eliminating the intermediary layer in the heat transfer path, heat loss during the transfer process is also reduced. This helps maintain a stable temperature within the baking device and improves baking efficiency. The close contact between the heating plate 11 and the heat conducting plate 12 creates a stable and uniform thermal environment for the battery baking process. This thermal environment ensures uniform heating of the battery during baking, improving the quality of the battery baking. Due to the high heat transfer efficiency and uniform temperature distribution, the baking process can be shortened, which helps improve battery production efficiency and reduce the energy cost of battery baking.

[0043] The heat conducting plate 12 also has a second surface 122 opposite the first surface 121. The second surfaces 122 of the multiple heat conducting plates 12 are interconnected to form a heat conducting region 120. The second surface 122 can be aligned with the bottom surface of the battery 2, ensuring close contact between the two opposing surfaces of the heat conducting plate 12 and the battery 2, thereby improving the heating effect of the heat conducting plate 12 on the battery 2.

[0044] The heating mechanism 1 further includes a fastener 13, through which the heat conducting plate 12 is detachably connected to the heating plate 11. When the heat conducting plate 12 or the heating plate 11 needs to be cleaned, repaired, or replaced, the detachable connection of the fastener 13 makes the disassembly between the heat conducting plate 12 and the heating plate 11 quick and easy, and the heat conducting plate 12 can be easily removed from the heating plate 11 without a complicated disassembly process.

[0045] The fastener 13 is a fastening screw. A connecting hole 123 is provided on the heat conducting plate 12 for the fastening screw to pass through, and a threaded hole 112 is provided on the heating plate 11 for cooperating with the fastening screw. The fastening screw provides a stable mechanical connection, ensuring that the heat conducting plate 12 and the heating plate 11 fit tightly together, and avoiding loosening or separation due to temperature changes or mechanical vibrations during the baking process. Screw connections usually have a high load-bearing capacity and can withstand the thermal and mechanical stresses generated during the baking process, ensuring the long-term stable operation of the baking device. Using fastening screws to connect the heat conducting plate 12 and the heating plate 11 makes the installation and disassembly process simple and quick. The screws can be easily tightened or loosened using only the right tools, without the need for complicated operating steps. Quick installation and disassembly can shorten the maintenance time of the baking device and improve production efficiency. It is also convenient for adjusting the position of the heat conducting plate 12 or replacing damaged parts as needed during the baking process.

[0046] The heat conducting plate 12 is provided with multiple connection holes 123. These holes provide multiple connection points between the heat conducting plate 12 and the heating plate, improving the stability of the connection between the two. The secure connection provided by the multiple fastening screws helps reduce the risk of failure due to a poor connection between the heating plate 11 and the heat conducting plate 12; this helps ensure the stability and reliability of the baking device over extended periods of operation.

[0047] In this embodiment, two connection holes 123 are defined on the heat conducting plate 12 , and the two connection holes 123 are respectively located at two ends of the heat conducting plate 12 .

[0048] In some embodiments, the thickness of the heat conducting plate 12 is amm, satisfying the following: 5≤a≤20. Using amm≥5mm provides the heat conducting plate 12 with better structural support to support the battery 2, reducing the risk of deformation and damage to the heat conducting plate 12. Using amm≤20mm provides the heat conducting plate 12 with a shorter heat conduction path, allowing the heat conducting plate 12 to quickly respond to temperature changes on the heating plate, helping to achieve uniform temperature distribution within the heat conducting area 120, ensuring that the battery 2 is evenly heated during the baking process, and thus improving the consistency of the baking effect.

[0049] Preferably, the heat conducting plate 12 is a metal heat conducting plate with good heat conducting effect. In the first embodiment, the heat conducting plate 12 is made of aluminum alloy.

[0050] In some other embodiments, the heat conducting plate 12 may be made of any material capable of achieving heat conduction, such as copper, copper alloy, iron, or iron alloy, and is not limited thereto.

[0051] In this first embodiment, the heating plate 11 has a rectangular structure, and the heat conducting plate 12 has a rectangular structure. The rectangular heat conducting plate 12 allows for flexible adaptation to various baking scenarios by adjusting the number and arrangement of the heat conducting plates 12 to accommodate the baking requirements of batteries 2 of varying sizes and shapes. It also allows for close arrangement of multiple heat conducting plates 12, avoiding gaps between any two adjacent heat conducting plates 12. This ensures that the heat conducting area 120 can fully contact and heat the batteries 2, improving the baking quality of the batteries 2. Compared to other shapes, the rectangular heat conducting plate 11 and heat conducting plate 12 are less likely to deform when heated, thereby maintaining a stable shape and size of the baking area.

[0052] The heating mechanism 1 also includes a base 14, which is connected to the side of the heating plate 11 facing away from the heat conducting plate 12. As a supporting structure for the heating plate, the base 14 can enhance the stability of the entire heating mechanism 1, ensuring that the heating plate can remain stable during the baking process and avoiding displacement or deformation caused by vibration or external forces.

[0053] The heating mechanism 1 further includes a tray 15 , which is used to carry the battery 2 to the heat conducting plate 12 for heating and baking.

[0054] Example 2

[0055] See Figure 6-Figure 7 , which is different from the first embodiment, the number of the heat conducting plates 12 is fourteen.

[0056] See Figure 8 The present invention also provides a battery baking device, which includes the heating mechanism 1 of any one of the above items, and also includes a box body 3 and a vacuum device 4. The box body 3 has a baking cavity 31, and the heating mechanism 1 is arranged in the baking cavity 31. The vacuum device 4 is connected to the box body 3 and is used to extract the gas in the baking cavity 31.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
