In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0029] The utility model is further described below in conjunction with embodiments. Example

[0030] Please refer to the attached Figure 1-4 This scheme proposes a cylindrical liquid filling tray reflux line drying bin conveying device, a nitrogen replacement box 2 and a drying bin 3 are arranged on the surface of the frame 1, the drying bin 3 is located on one side of the nitrogen replacement box 2, and a transition bin door 4 is also installed on the surface of the frame 1, the transition bin door 4 is located between the nitrogen replacement box 2 and the drying bin 3, and the transition bin door 4 is used to seal the connection between the nitrogen replacement box 2 and the drying bin 3.

[0031] A liquid injection door 5 is installed on the surface of the nitrogen replacement box 2 facing the battery production line. The liquid injection door 5 is used to control the sealing switch in the battery production line.

[0032] In this solution, after the liquid filling tray flows back out from the battery production line, it first enters the nitrogen replacement box 2 through the liquid filling door 5, and then passes through the transition chamber door 4 and enters the drying chamber 3. The other end of the drying chamber 3 is connected to the cleaning device, so that the liquid filling tray can enter the cleaning device for cleaning after completing drying in the drying chamber 3.

[0033] A nitrogen replacement mechanism 6 is installed on the upper end surface of the nitrogen replacement box 2 . The nitrogen replacement mechanism 6 includes an air inlet pipe for filling nitrogen into the nitrogen replacement box 2 and a pressure relief pipe for extracting air from the nitrogen replacement box 2 .

[0034] Nitrogen can be injected into the nitrogen replacement box 2 through the nitrogen replacement mechanism 6, and the air in the nitrogen replacement box 2 can be replaced by nitrogen. When the liquid injection tray is ready to enter the nitrogen replacement box 2, the nitrogen replacement box 2 is first sealed and controlled through the transition chamber door 4 and the liquid injection door 5, and then the air in the nitrogen replacement box 2 is replaced by the nitrogen replacement mechanism 6. After the air replacement is completed in the nitrogen replacement box 2, the liquid injection door 5 is opened. At this time, the gas in the nitrogen replacement box 2 is nitrogen. When the liquid injection tray in the battery production line enters the nitrogen replacement box 2, the flow of air into the battery production line can be reduced, thereby preventing moisture in the air from entering the battery production line, resulting in excessive moisture in the battery production line, and resulting in reduced production quality. After the liquid injection tray enters the nitrogen replacement box 2, the liquid injection door 5 is closed, and the transition chamber door 4 is opened, so that the transportation device in the nitrogen replacement box 2 can move the liquid injection tray to the inside of the drying chamber 3, which is convenient for the drying chamber 3 to dry the liquid injection tray.

[0035] Specifically, a conveying channel 7 is provided inside the drying bin 3, and a conveying mechanism 8 is installed inside the conveying channel 7. The conveying channel 7 faces the transition bin door 4 and both sides of the cleaning device respectively. The cleaning device is used to clean impurities and electrolyte attached to the tray. It is a well-known technology and will not be described in detail here. It is not shown in the drawings.

[0036] After the liquid filling tray in the nitrogen replacement box 2 passes through the transition chamber door 4 and enters the conveying channel 7, the liquid filling tray can be supported by the conveying mechanism 8, and the liquid filling tray is conveyed in the conveying channel 7 from the nitrogen replacement box 2 to the side of the cleaning device. During the movement, it is connected through the interior of the drying chamber 3 and the drying pipe on the drying device to realize the drying operation of the liquid filling tray inside the drying chamber 3.

[0037] More specifically, the conveying mechanism 8 includes two sets of fixed frames 801 installed inside the drying chamber 3, and conveyor belts 802 are installed on the two sets of fixed frames 801. The two sets of conveyor belts 802 are parallel to the conveying channel 7. The conveying mechanism 8 also includes a driving motor A803 installed in the drying chamber 3, and the driving motor A803 is used to drive the two sets of conveyor belts 802 to operate. After the liquid injection tray enters the conveying channel 7, the liquid injection tray will move to the surface of the two sets of conveyor belts 802, and the liquid injection tray will be supported by the two sets of conveyor belts 802, and the conveyor belts 802 are driven to rotate by the driving motor A803 to realize the movement of the liquid injection tray.

[0038] The conveying mechanism 8 also includes two sets of slide rails 804 installed on the frame 1. The two sets of slide rails 804 are arranged in parallel, and the slide rails 804 and the conveying channel 7 are arranged vertically. Two sets of slide platforms 805 are respectively arranged on each set of slide rails 804, and the fixed frame 801 is installed above the two sets of slide platforms 805 on the same side of the two sets of slide rails 804. The surfaces of the two sets of slide platforms 805 installed on one set of fixed frames 801 are both provided with racks 806, and the two sets of racks 806 installed on the two sets of slide platforms 805 are symmetrically arranged. At the same time, a driving motor B807 is installed inside the drying chamber 3, and a control gear 808 is arranged on the output shaft of the driving motor B807. The control gear 808 is located between the two sets of racks 806, and the control gear 808 is meshed and connected with the two sets of racks 806 at the same time.

[0039] When the conveying mechanism 8 is conveying the liquid injection tray, the driving motor B807 is turned on to drive the control gear 808 to engage the two sets of racks 806 to slide, and the sliding directions of the two sets of racks 806 are opposite.

[0040] By controlling the relative sliding of the fixed frame 801, the spacing between the two sets of conveyor belts 802 can be adjusted, so that the conveying mechanism 8 can convey liquid injection trays of different sizes.

[0041] Each set of fixing frames 801 is provided with mounting seats 809 at both ends. A sleeve shaft 810 and a cannula shaft 811 are respectively inserted and installed in the two sets of mounting seats 809 on the same side of the two sets of fixing frames 801. The cannula shaft 811 is inserted and installed in the sleeve shaft 810, and the cannula shaft 811 and the sleeve shaft 810 are slidably connected. The surfaces of the cannula shaft 811 and the sleeve shaft 810 are provided with driving wheels 812, and the conveyor belt 802 is installed on the two sets of driving wheels 812 on the same side.

[0042] The output shaft of the driving motor A803 and the surface of one group of pulleys 813 are both provided with pulleys 813, and the two groups of pulleys 813 are connected by a connecting belt 814. When the driving motor A803 is turned on, the cannula shaft 811 is driven to rotate by the pulley 813 and the connecting belt 814.

[0043] The cannula shaft 811 is connected to the concentrically distributed sleeve shaft 810 for rotation, so that the two sets of driving wheels 812 on the same side of the two sets of fixing frames 801 can rotate synchronously.

[0044] The conveyor belt 802 is driven to rotate by the driving wheel 812, so that the conveying mechanism 8 can drive the liquid injection tray. When the spacing between the two sets of conveyor belts 802 is adjusted, the insertion shaft 811 and the sleeve shaft 810 slide relative to each other, and the rotation drive of the driving wheel 812 can be effectively guaranteed while adjusting the spacing between the two sets of driving wheels 812.

[0045] The two sets of fixed frames 801 are respectively provided with a plurality of guide wheels 815 which are linearly distributed at equal distances. When the liquid injection tray is transported on the surfaces of the two sets of conveyor belts 802, the liquid injection tray is limited by the guide wheels 815 on both sides to prevent the liquid injection tray from sliding off the conveyor belts 802. The conveyor belts 802 are hingedly mounted on the fixed frames 801.

[0046] The sliding friction between the liquid injection tray and the conveyor belt 802 is converted into rolling friction, which improves the smoothness of the liquid injection tray conveyed by the conveying mechanism 8. The spacing between the two sets of guide wheels 815 is adjusted along with the spacing between the two sets of fixing frames 801, so that the guide wheels 815 on both sides can always limit the liquid injection tray.

[0047] A support plate 816 is also installed on the surface of the fixed frame 801 and is located below the upper end surface of the conveyor belt 802, so that when the liquid injection tray is supported by the conveyor belt 802, the support plate 816 can provide stable support for the liquid injection tray and ensure the structural stability of the conveying mechanism 8.

[0048] The surface of the frame 1 is provided with an electric control box 9, which is located below the drying chamber 3. The surface of the frame 1 is also provided with a man-machine operation terminal 10. Through the electric control box 9 and the man-machine operation terminal 10, the automatic control of the device can be realized, including the electric control opening of the transition chamber door 4 and the injection door 5, and the operation control of the conveying mechanism 8.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents.
