Description

Technical Field

[0001] This utility model relates to the field of lithium battery production technology, specifically to a drying equipment for lithium battery production and processing. Background Technology

[0002] The main purpose of drying in lithium battery production is to remove moisture and impurities to ensure the battery's performance stability and safety. The presence of moisture and impurities can negatively affect the battery's electrochemical performance, leading to problems such as decreased battery capacity, increased internal resistance, and shortened cycle life. Therefore, drying is necessary for lithium battery cells.

[0003] Currently, existing drying equipment typically uses a multi-layer stacking method to dry battery cells. During use, although the drying chamber is equipped with a temperature control system and a ventilation system, the overlapping of multiple battery cells leads to inconsistent drying effects between the upper and lower layers. The upper layer of cells requires a longer drying time to achieve the same drying effect as the lower layer, resulting in an overall long drying time. Furthermore, over-drying of the lower layer of cells can lead to a decrease in the performance of the lithium battery and even damage. Based on this, a drying equipment for lithium battery production and processing is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for lithium battery production and processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for lithium battery production and processing, comprising a base, a housing mounted on the upper end of the base, a drying chamber disposed inside the housing, a rotating support shaft rotatably connected through the rear end of the drying chamber, a rotating disk mounted at the front end of the rotating support shaft inside the drying chamber, a drive assembly mounted at the rear end of the rotating support shaft, a plurality of placement rods mounted at the front end of the rotating disk, a plurality of placement baskets placed on the surface of the placement rods, connecting rods mounted at both the front and rear ends of the upper end of the placement baskets, a ring mounted at the upper end of the connecting rods, the ring fitting onto the surface of the placement rods, a sealing door mounted at the front end of the housing, and a drying device mounted at one end of the surface of the housing.

[0006] Preferably, the drive assembly includes a drive motor, a drive gear, a mounting bracket, and a meshing gear. The meshing gear is mounted on the rear end of the rotating support shaft, and the mounting bracket is mounted on the rear end of the housing on one side of the meshing gear. The drive motor is mounted on the mounting bracket, and the drive gear is mounted on the output end of the drive motor. The drive gear and the meshing gear mesh with each other.

[0007] Preferably, an insulation layer is installed inside the inner wall of the housing.

[0008] Preferably, the surface of the placement rod is provided with a plurality of circular grooves, and the ring body is located inside the circular grooves.

[0009] Preferably, the sealed door is provided with an observation window.

[0010] Preferably, the placement basket is made of a mesh material.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This drying equipment for lithium battery production and processing uses a drive assembly to drive a rotating disk on a rotating support shaft to rotate. The rotating disk drives a placement basket on a placement rod to rotate. Under the action of gravity, the placement basket is always in a vertically downward state, realizing the moving and drying of lithium battery cells inside the placement basket. This effectively avoids the phenomenon of different drying effects of lithium battery cells caused by obstruction.

[0013] 2. This drying equipment for lithium battery production and processing allows for the placement of lithium battery cells in a pre-prepared basket. After the lithium batteries are dried, the basket is simply removed and replaced with a basket containing the batteries to be dried, effectively improving drying efficiency. At the same time, the circular groove on the placement rod limits the movement of the ring, effectively preventing it from accidentally falling off when rotating around the surface of the placement rod.

[0021] like Figures 1 to 4 As shown, the drying equipment for lithium battery production and processing in this embodiment includes a base 1, a housing 2 mounted on the upper end of the base 1, a drying chamber 3 inside the housing 2, a rotating support shaft rotatably connected to the rear end of the drying chamber 3, a rotating disk 5 mounted at the front end of the rotating support shaft inside the drying chamber 3, a drive assembly mounted at the rear end of the rotating support shaft, several placement rods 7 mounted at the front end of the rotating disk 5, several placement baskets 8 placed on the surface of the placement rods 7, the placement baskets 8 are used to place the battery cells during lithium battery production, connecting rods 9 are mounted at both the front and rear ends of the upper end of the placement baskets 8, and rings 10 are mounted on the upper ends of the connecting rods 9, the rings 10 are sleeved on the surface of the placement rods 7, the drive assembly drives the rotating disk 5 to rotate via the rotating support shaft. The rotating disk 5 drives the placement basket 8 on the surface of the placement rod 7 to rotate. At the same time, under the action of gravity, the placement basket 8 is always in a vertically downward direction, and the battery cells inside the placement basket 8 are moved and dried, effectively avoiding the phenomenon of uneven drying of some battery cells due to obstruction. A sealing door 11 is installed at the front end of the housing 2. The sealing door 11 is set to facilitate the placement basket 8 to be put into the drying chamber 3 and taken out of the drying chamber 3. A drying device 14 is installed at one end of the surface of the housing 2. The drying device 14 is used to discharge dry air into the drying chamber 3 to achieve the drying of lithium battery cells. In the field of drying equipment technology, the working principle of the drying device 14 is a known prior art, so it will not be described in detail.

[0022] Specifically, the drive assembly includes a drive motor 601, a drive gear 602, a mounting bracket 603, and a meshing gear 604. The meshing gear 604 is mounted on the rear end of the rotating support shaft, and the mounting bracket 603 is mounted on the rear end of the housing 2 on one side of the meshing gear 604. The drive motor 601 is mounted on the mounting bracket 603, and the drive gear 602 is mounted on the output end of the drive motor 601. The drive gear 602 and the meshing gear 604 mesh with each other. The drive motor 601 drives the drive gear 602 to rotate, and the drive gear 602 drives the rotating disk 5 to rotate through the meshing gear 604 and the rotating support shaft, thereby driving the rotation of the rotating disk 5 and facilitating the movement and drying of the lithium battery cells inside the basket 8.

[0023] Furthermore, an insulation layer 12 is installed inside the inner wall of the shell 2. The insulation layer 12 is made of polyurethane material. The installation of the insulation layer 12 effectively prevents heat loss inside the drying chamber 3 and reduces the energy consumption of the drying device 14.

[0024] Furthermore, the surface of the placement rod 7 is provided with several circular grooves 13, and the ring 10 is located inside the circular grooves 13. The circular grooves 13 limit the ring 10, effectively preventing the ring 10 from accidentally falling off when it rotates around the surface of the placement rod 7. The inner diameter of the ring 10 is larger than the diameter of the placement rod 7.

[0025] Furthermore, the sealed door 11 is provided with an observation window 4, which facilitates the observation of the drying status inside the drying chamber 3.

[0026] Furthermore, the placement basket 8 is made of a mesh material. The mesh material of the placement basket 8 reduces the contact area between the lithium battery cell and the placement basket 8, making it easier to dry the cell without any dead angles.

[0027] The usage method of this embodiment is as follows: First, open the sealing door 11, and suspend the placement basket 8 containing the lithium battery cells to be dried on the placement rod 7 through the ring 10. The ring 10 is located inside the circular groove 13. Adjust the rotation of the rotating disk 5 so that the placement basket 8 is suspended on the placement rod 7. During the drying process, the drying device 14 generates dry air and discharges the dry air into the drying chamber 3. At the same time, the drive motor 601 in the drive assembly drives the drive gear 602 to rotate. The drive gear 602 drives the rotating disk 5 to rotate through the meshing gear 604 and the rotating support shaft, thereby driving the rotation of the rotating disk 5. When the rotating disk 5 rotates, the placement basket 8 is always in a vertically downward state under the action of gravity. At the same time, the ring 10 rotates around the surface of the placement rod 7. The rotating disk 5 drives the placement basket 8 to move and dry. After the drying is completed, the placement basket 8 is taken out and then placed into the placement basket 8 containing the undried lithium battery cells for a second drying process.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
