In order to achieve water absorption without affecting the drying efficiency, a water absorption mechanism 8 is provided on the surface of the door panel 3. The water absorption mechanism 8 includes a box body 801, a bottom plate 802, and a silica gel desiccant 803. The box body 801 is fixed to the surface of the door panel 3, and the bottom plate 802 is slidably connected to the door panel 3. The inner wall of the box 801 has silica gel desiccant 803 placed on the top surface of the base plate 802. The surface of the base plate 802 is provided with a reset component 9, which is connected to the box 801. The surface of the door panel 3 is provided with a locking component 10. The surface of the slide plate 4 is provided with placement grooves, which are evenly distributed on the surface of the slide plate 4. In order to make the door panel 3 pull the slide plate 4 to move when opening and closing, thereby reducing the material picking time, a tension component 6 is provided. The tension component 6 includes a first connecting rod 601 and a second connecting rod 602. The first connecting rod 601 is hinged to the surface of the upper limit rod 5 of the slide plate 4, and the second connecting rod 602 is hinged to the surface of the upper limit rod 5 of the door panel 3. The first connecting rod 601 and the second connecting rod 602 are hinged to each other.

[0029] To dry the lithium battery after the separator coating is completed, and to facilitate temperature control, a drying structure 7 is provided. The drying structure 7 includes a heating element 701 and a temperature controller 702. The heating element 701 is fixed to the surface of the drying chamber 1, and the temperature controller 702 is electrically connected to the surface of the heating element 701 via a relay. The temperature controller 702 is fixed to the outer wall of the drying chamber 1 with screws. To facilitate the lifting and removal of the silica gel desiccant 803 from the housing 801 for replacement, a reset component 9 is provided. The reset component 9 includes a lever 901 and a spring 902. The grab bar 901 is fixed to the bottom of the base plate 802, and the end of the grab bar 901 extends through the interior of the box body 801. The spring 902 is nested and fixed to the surface of the grab bar 901, and the end of the spring 902 is fixed to the outer wall of the box body 801. In order to improve the stability of the door panel 3 when it is closed, a locking component 10 is provided. The locking component 10 includes a rotating shaft 1001 and a fixing handle 1002.

[0030] The thermostat 702 is model XTMD-100, and this model comes with a built-in thermocouple.

[0031] Working principle or structural principle: When drying lithium batteries with coated separators is required, the operator can rotate the fixing handle 1002 to disengage it from the clamping plate 2, and then rotate the door panel 3. During the rotation of the door panel 3, the sliding plate 4 is dragged outward through the first connecting rod 601 and the second connecting rod 602, making it easier for the operator to place the lithium battery inside the placement slot. After that, the above operation is reversed to complete the loading. Next, the operator can use the temperature controller 702 to control the temperature of the heating tube 701 to complete the drying operation. During the drying process, the silica gel desiccant 803 will absorb the moisture inside the drying chamber 1, thereby improving the drying effect. After drying is completed, the door panel 3 is opened again to remove the lithium battery.

[0032] If the silica gel desiccant 803 needs to be replaced, the staff can open the door panel 3 and lift the bottom plate 802 using the grab bar 901 to make it easier for the staff to grasp the silica gel desiccant 803. After the replacement is completed, release the grab bar 901, and the spring 902 will drive it and the bottom plate 802 to move down and reset. This completes the entire replacement process.

[0033] In summary, this device has the advantages of easy replacement of water-absorbing parts and high drying efficiency.
