Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying equipment technology, and in particular to a battery cell aluminum shell drying device. Background Technology
[0002] Battery cell aluminum shells are generally made by stamping and stretching aluminum sheets. During the stamping process, oil needs to be sprayed onto the surface of the aluminum sheet for lubrication to prevent scratches. After stamping, cleaning is required to remove the lubricating oil adhering to the surface of the battery cell aluminum shell. After cleaning, the battery cell aluminum shell needs to be dried. For battery cell aluminum shells that are cylindrical, one end is open, and its inner cavity may contain flowing water (i.e., a large amount of water can collect and flow). Existing battery cell aluminum shell drying devices include tunnel heating furnaces with openings at both ends. A conveyor belt passes through the heating furnace, and the battery cell aluminum shell is placed flat on the conveyor belt and then passes through the heating furnace to be dried. However, because the battery cell aluminum shell is in a flat state, the water inside does not easily flow out, thus requiring a longer drying time. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a battery cell aluminum shell drying device in response to the above-mentioned technical deficiencies.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a battery cell aluminum shell drying device, including a tunnel heating furnace, a conveyor belt passing through the heating furnace, a plurality of protrusions provided on the conveyor belt, the extension direction of the protrusions being perpendicular to the extension direction of the conveyor belt, a toggle assembly rotatably connected inside the heating furnace, the toggle assembly including a lever, both ends of the lever being provided with long cantilever arms, and the end of the long cantilever arm away from the lever being provided with a short cantilever arm for interacting with the protrusions to lift the lever.
[0005] To further optimize this technical solution, a rotating shaft is provided on the outer side of the short cantilever, and a cylinder for rotating connection with the rotating shaft is provided on the inner wall of the heating furnace.
[0006] To further optimize this technical solution, a support rod is also provided on the inner wall of the heating furnace, and the support rod is located below the long cantilever.
[0007] To further optimize this technical solution, the lever is rotatably connected to the long cantilever.
[0008] Compared with the prior art, the present invention has the following advantages: the conveyor belt is provided with multiple protrusions, which can place the end of the aluminum shell of the battery cell away from the opening on the protrusions, so that the water inside can easily flow out from the opening. In addition, a toggle assembly is rotatably connected inside the heating furnace. When the opening of the aluminum shell of the battery cell contacts the lever on the toggle assembly, it will slide relative to the conveyor belt, so that the end with the opening is higher, and the water vapor inside can easily escape.

[0012] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0013] Detailed implementation method: combined with Figure 1-2 As shown, a battery cell aluminum shell drying device includes a tunnel-type heating furnace 1. The heating furnace 1 is equipped with heating elements and temperature measuring elements (not shown in the figure) and is controlled by a controller. The temperature inside the heating furnace 1 is about 90°C. A conveyor belt 2 passes through the heating furnace 1. The conveyor belt 2 is a heat-resistant conveyor belt. The conveyor belt 2 is provided with multiple protrusions 21. The cross-section of the protrusions 21 is rectangular or semi-circular. The extension direction of the protrusions 21 is perpendicular to the extension direction of the conveyor belt 2. A toggle assembly 3 is rotatably connected inside the heating furnace 1. The toggle assembly 3 includes a lever 31. Both ends of the lever 31 are provided with long cantilever arms 32. The end of the long cantilever arm 32 away from the lever 31 is provided with a short cantilever arm 34 for interacting with the protrusions 21 to lift the lever 31.
[0014] Specifically, a rotating shaft 33 is provided on the outer side of the short cantilever 34, and a shaft cylinder 11 for rotatably connecting with the rotating shaft 33 is provided on the inner wall of the heating furnace 1. The height of the shaft cylinder 11 is higher than the top of the protrusion 21. In its natural state, the lower end of the short cantilever 34 is higher than the surface of the conveyor belt 2 and lower than the top of the protrusion 21.
[0015] Preferably, a support rod 12 is also provided on the inner wall of the heating furnace 1, and the support rod 12 is located below the long cantilever 32. In this case, the lever 31 will not contact the conveyor belt 2. Preferably, when the long cantilever 32 rests on the support rod 12, the long cantilever 32 is in a horizontal state and the short cantilever 34 is in a vertical state. At this time, the lever 31 is lower than the top of the opening of the aluminum shell of the battery cell.
[0016] Preferably, the lever 31 is rotatably connected to the long cantilever 32.
[0017] When using, combine Figure 1-2 As shown, the aluminum battery shell is placed at the right end of the conveyor belt 2, with the end of the aluminum battery shell furthest from the opening placed on the protrusion 21 (only one aluminum battery shell is placed on each protrusion 21, or the aluminum battery shells on each protrusion 21 are in a straight line). At this time, the left end of the aluminum battery shell is open. Since the aluminum battery shell is in an inclined state, the water inside (if there is enough to flow) can flow out from the opening, making it easier for the aluminum battery shell to be dried. When the opening of the aluminum battery shell touches the lever 31, it will be difficult to continue moving to the left, so it will slide relative to the conveyor belt 2, making the opening of the aluminum battery shell closer to the protrusion 21, thus placing the opening of the aluminum battery shell at a higher position. The position of the lever 31 makes it easier for moisture to escape from the aluminum shell of the battery cell, making it easier to dry. When the protrusion 21 touches the short cantilever 34, the long cantilever 32 will rotate, so that the height of the lever 31 is higher than the top of the opening of the aluminum shell of the battery cell. At this time, the aluminum shell of the battery cell will move with the conveyor belt 2 and the protrusion 21 will be located below the aluminum shell of the battery cell near the opening. When the protrusion 21 is separated from the short cantilever 34, the lever 31 falls on the upper side of the aluminum shell of the battery cell, so that the obstruction effect on the aluminum shell of the battery cell is small. At this time, the aluminum shell of the battery cell basically does not move relative to the conveyor belt 2. When the lever 31 is rotatably connected to the long cantilever 32, the obstruction effect of the lever 31 on the aluminum shell of the battery cell is even smaller.
[0018] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
