[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] This embodiment discloses a lithium battery drying device, such as... Figures 1 to 4 As shown, this utility model has high drying efficiency and is convenient for drying a large number of lithium batteries. It includes a drying box 1, in which a rotating rod 2 is provided; several placement boxes 3 are provided on the rotating rod 2; ventilation nets 4 are provided on both sides and the bottom of the placement boxes 3; a mating groove 5 is provided on the placement box 3; a vertical rod 6 is provided at the bottom of the placement box 3; the placement boxes 3 are connected to each other by the vertical rod 6 and the mating groove 5; a hot air blower 7 and a fan motor 8 are provided on the outside of the drying box 1; an air outlet pipe 9 and a fan blade 10 are provided inside the drying box 1; the fan blade 10 is located between the air outlet pipes 9.

[0021] By adopting the above technical solution: during drying, the lithium battery is placed in the placement box 3, the hot air blower 7 is turned on, and the hot air enters the box through the air outlet pipe 9. Ventilation nets 4 are provided on both sides and the bottom of the placement box 3 to facilitate the entry of hot air into the placement box 3 and thus dry the lithium battery; after the rotating rod 2 rotates, it drives the placement box 3 to rotate, thereby driving the lithium battery to rotate. Since the lithium battery is rotating during drying, the drying efficiency is high; the vertical rod 6 on the upper placement box 3 cooperates with the matching groove 5 in the lower placement box 3 to make the placement boxes 3 stable; when drying a large number of lithium batteries, a corresponding number of placement boxes 3 can be placed on the rotating rod 2 to facilitate the drying of a large number of lithium batteries; the fan blade 10 on one side is located between the air outlet pipes 9 on the same side, so that the hot air is blown out of the air outlet pipes 9 faster and the convection of the hot air in the drying box 1 is enhanced.

[0022] like Figure 1 , Figure 6 As shown, the rotating rod 2 is connected to the rotating motor 11; the rotating rod 2 has a rod groove 12; the placement box 3 has a protrusion 13; the protrusion 13 cooperates with the rod groove 12; the rotating rod 2 is also provided with an inclined rod 14; the inclined rod 14 is located at the bottom of the lowest placement box 3.

[0023] By adopting the above technical solution: after the protrusion 13 cooperates with the rod groove 12, the placement box 3 and the rotating rod 2 are stably connected; the inclined rod 14 supports the lowermost placement box 3, so that the lowermost placement box 3 is stably set on the rotating rod 2; after the vertical rod 6 on the upper placement box 3 cooperates with the mating groove 5 in the lower placement box 3, the placement boxes 3 are stably set together; after the rotating motor 11 is started, it drives the rotating rod 2 to rotate, thereby driving the placement box 3 to rotate.

[0024] like Figure 3 , Figure 4 , Figure 5As shown, the placement box 3 is provided with box panels 15; a limiting plate 16 is provided between the box panels 15; a plate groove 17 is provided on the limiting plate 16; a slider 18 is provided on the plate groove 17; the slider 18 is connected to a partition plate 19; the partition plate 19 moves on the limiting plate 16 through the slider 18; a plate hole 20 is provided on the partition plate 19.

[0025] By adopting the above technical solution: during drying, the limiting plate 16 is placed between the box plates 15, and the partition plate 19 can move on the limiting plate 16 by the slider 18 according to the size of the lithium battery, thereby limiting the lithium battery during drying and preventing the lithium battery from moving at will. There is a certain friction between the plate groove 17 and the slider 18, thereby preventing the slider 18 from moving at will on the plate groove 17. When the limiting plate 16 and the partition plate 19 are located between the box plates 15, the thickness of the limiting plate 16 plus the height of the partition plate 19 is less than the height of the placement box 3, thereby preventing the limiting plate 16 from detaching from the placement box 3 when the placement box 3 rotates. When the partition plate 19 limits the lithium battery, hot air can pass through the plate hole 20 to dry the lithium battery.

[0026] like Figure 1 As shown, the drying oven 1 has a door 21; the door 21 has a notch 22; a transparent plate 23 is provided at the notch 22; and a thermometer 24 is provided inside the drying oven 1.

[0027] By adopting the above technical solution: the door 21 seals the drying chamber 1 to prevent heat from dissipating too quickly during drying; the notch 22 and the transparent plate 23 make it easy for people to see the temperature on the thermometer 24 so as to adjust the air volume of the hot air blower 7 during drying; the door 21 is connected to the drying chamber 1 by a hinge, the hinge is located inside the drying chamber 1 and the hinge is a hinge spring hinge.

[0028] like Figure 1 , Figure 2 As shown, a ventilation pipe 25 is provided above the drying box 1; a pipe block 26 is provided inside the ventilation pipe 25; a sealing plate 27 is provided on the ventilation pipe 25; the sealing plate 27 passes through one side of the ventilation pipe 25 and one end is located on the pipe block 26.

[0029] By adopting the above technical solution: the ventilation pipe 25 facilitates the discharge of moisture in the drying chamber 1. During drying, the interior of the drying chamber 1 can be observed through the transparent plate 23 and the notch 22. If there is moisture in the drying chamber 1, the sealing plate 27 can be removed from the pipe block 27 and the ventilation pipe 25. After the moisture is discharged, the sealing plate 27 is inserted through one end of the ventilation pipe 25 and placed on the pipe block 26.

[0030] In summary, this utility model has the following beneficial effects: a hot air blower 7 and an air outlet pipe 9 are respectively installed inside the drying chamber 1 to blow hot air into the drying chamber 1 to dry the lithium battery. The fan motor 8 drives the fan blades 10 to rotate, which can enhance the convection of hot air, so that the hot air is blown out of the air outlet pipe 9 more quickly and enhance the convection of hot air in the drying chamber 1. The rotating motor 11 drives the rotating rod 2 to prevent the chamber from rotating. Ventilation nets 4 are provided on both sides and the bottom of the placement box 3 to facilitate the hot air to blow over all sides of the lithium battery, thereby improving the drying efficiency.

[0031] When drying a large number of lithium batteries, a corresponding number of placement boxes 3 can be placed on the rotating rod 2 to facilitate the drying of a large number of lithium batteries.
