[0023] The detailed working process of this embodiment is as follows: the function of hinged movable doors 3 at both ends of the channel 101 is to reduce the heat loss in the box body 2.

[0024] Under the setting of the conveying part, the placement part for placing lithium batteries can be driven into the box body 2 along the slide 102, and baked and dehumidified by the heating device in the box body 2. After baking for a specified time, it is driven out of the box body 2. When the placement part leaves the box body 2, another placement part enters the box body 2 and is baked. While the placement part in the box body 2 is baking, the placement part outside the box body 2 is in a cooling state. After waiting for cooling, the placement part can be removed from the conveying part. The above steps can be repeated to realize the assembly line dehumidification process of the lithium battery. When baking in the box body 2, the driving part drives the placement part to rotate at a uniform speed in the box body 2, so that each lithium battery is heated evenly, thereby improving the dehumidification quality.

[0025] like Figure 1 As shown, the transmission member includes two sets of sprockets 201 and a steel cable 1 connected to the two sprockets 201 , and the steel cable 1 is located above the slide 102 .

[0026] The detailed working process of this embodiment is as follows: two sets of sprockets 201 are arranged on the upper side of the box body 2, one of the sprockets 201 is connected to an external power, and rotates to drive the steel cable 1 to move, thereby driving the placement piece to pass through the box body 2.

[0029] like Figure 2 and Figure 4 As shown, the driving member includes a mounting frame 5 arranged at the output end of the cylinder 501, two driving wheels 502 rotatably arranged on the mounting frame 5, and a driving source 504 arranged on the mounting frame 5 and transmission-connected to any one of the driving wheels 502. Both driving wheels 502 are provided with pulleys 503, and the two pulleys 503 are transmission-connected through a transmission belt 505. The two driving wheels 502 are in contact with the driven wheel 403 under the setting of the cylinder 501.

[0030] The detailed working process of this embodiment is as follows: the cylinder 501 is used to control the driving member to approach or move away from the driven wheel 403, the driving source 504 is used to drive the corresponding driving wheel 502 to rotate, and the other driving wheel 502 is driven to rotate synchronously through the transmission belt 505. When it is necessary to drive the placement plate 4 to rotate, the cylinder 501 is first controlled to drive the two driving wheels 502 to abut against the driven wheel 403, and then the driving source 504 is energized to rotate it. The driving source 504 drives the two driving wheels 502 to rotate, and the two driving wheels 502 drive the driven wheel 403 to rotate, thereby driving the placement plate 4 to rotate.

[0031] The driving source 504 in this embodiment is a motor. In other embodiments, a suitable power source can be selected according to actual conditions.

[0032] like Figure 3 As shown, the heating device includes heating rods 104 arranged on both side walls inside the box 2.

[0033] The detailed working process of this embodiment is as follows: the function of the heating rod 104 is to heat the inside of the box 2 .

[0034] like Figure 2 As shown, a torsion spring 301 is provided at the hinge of each movable door 3 .

[0035] The detailed working process of this embodiment is as follows: the function of the torsion spring 301 is to enable each movable door 3 to automatically return to the initial position, thereby reducing the heat loss in the box body 2.

[0036] like Figure 3 As shown, a limiting strip 302 is provided on one side of each movable door 3 .

[0037] The detailed working process of this embodiment is as follows: the function of the limiting strip 302 is to limit the movable door 3 to prevent the movable door 3 from swinging too much and for too long due to the rebound force of the torsion spring 301 .

[0041] The detailed working process of this embodiment is as follows: the heat insulating material can reduce the loss of heat in the box body 2 and prevent the outer shell of the box body 2 from heating up and affecting the surrounding environment.

[0042] The implementation principle of the embodiment of the present application is as follows: first, multiple groups of placement trays 4 are evenly hung on the steel cable 1 through the hanging seat 402, and the lithium batteries that need to be dehumidified are placed in the placement trays 4. Then, the driving sprocket 201 rotates intermittently to drive the steel cable 1 to move, thereby driving the placement trays 4 to enter the box body 2. When the placement trays 4 contact the movable door 3 and push it open, the torsion spring 301 accumulates force. When the placement trays 4 pass the movable door 3, the movable door 3 returns to its initial position and remains under the torsion of the torsion spring 301. When the placement trays 4 move into the box body 2 and then pause, the control cylinder 501 drives the two active wheels 502 and the driven wheels 4 03 is in contact, and then the driving source 504 is energized to rotate it. The driving source 504 drives the two active wheels 502 to rotate. The two active wheels 502 drive the driven wheels 403 to rotate, thereby driving the placement tray 4 to rotate, thereby performing a dehumidification process on the lithium battery. After dehumidification is completed, the placement tray 4 leaves the box body 2 while another placement tray 4 enters the box body 2 and is baked. While the placement tray 4 in the box body 2 is baking, the placement tray 4 outside the box body 2 is in a cooling state. After waiting for cooling, the placement piece can be removed from the conveyor. The above steps can be repeated to realize the assembly line type dehumidification process for the lithium battery.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
