Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary equipment for lithium battery production, and particularly relates to a device for cleaning the inner wall of a lithium battery aluminum shell. Background Art

[0002] As an important protection device for lithium batteries, if the inner wall of the aluminum shell of the lithium battery is not cleaned before the battery core is put into the shell, metal burrs or impurities in the aluminum shell will affect the welding of the top cover after the battery core is put into the shell. During pre-welding, these metal burrs will cause black explosion points on the aluminum shell and the aluminum top cover, resulting in the scrapping of the aluminum shell, affecting the production efficiency of lithium batteries, and the scrapping of the aluminum shell also increases the production cost.

[0003] The existing aluminum shell cleaning devices are mainly divided into two types. One is to wash the aluminum shell with high-pressure water, and the second is to clean the aluminum shell with an ultrasonic cleaning device. Although both of these methods can clean the aluminum shell, the aluminum shell cannot be immediately put into production after cleaning and needs to be dried or air-dried before it can be put into use, resulting in a long waiting time and affecting the normal production of lithium batteries. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a device for cleaning the inner wall of a lithium battery aluminum shell, so as to solve the problems in the prior art that metal burrs in the aluminum shell affect the welding of the aluminum shell and the top cover, are prone to black explosion points, resulting in the scrapping of the aluminum shell, the aluminum shell after being cleaned by the cleaning device cannot be immediately put into production, the waiting time is long, the production efficiency of lithium batteries is low, and the scrapped aluminum shell increases the production cost.

[0005] To achieve the above purpose, the technical solution of the utility model is: a device for cleaning the inner wall of a lithium battery aluminum shell, including a platform, a fixed seat is arranged in the middle of the platform, one side of the end of the fixed seat is fixedly connected with a fixed column, a rotating plate is rotatably connected to the fixed column through a bearing, one end of the rotating plate is fixedly connected with a fixing plate, through holes are opened at the four corners of the fixing plate, a vacuum suction pipe is fixedly connected in the through holes, one end of the vacuum suction pipe is fixedly connected with a suction cup, and a cleaning mechanism is arranged on one side of the fixed seat;

[0006] The cleaning mechanism includes a cleaning mold, an air guide pipe, a dust collection cover, a dust collection suction pipe and a dust collection plate. A dust collection plate fixedly connected to the platform is arranged on one side of the fixed seat. At least 8 dust collection through holes are arranged on the dust collection plate. A cleaning mold is fixedly connected to the middle of the dust collection plate. The volume of the cleaning mold is smaller than the volume of the lithium battery aluminum shell. A plurality of air guide through holes are opened on the surface of the cleaning mold. A dust collection cover fixedly connected to the platform is arranged at the bottom of the dust collection plate. A dust collection suction pipe is fixedly connected to the dust collection cover. The air guide pipe penetrates through the dust collection cover and the dust collection plate and is fixedly connected to the bottom of the cleaning mold.

[0008] Preferably, limit plates fixedly connected to the platform are provided around the cleaning mold.

[0009] Preferably, a positioning baffle is provided at one end of the fixing plate.

[0010] The advantages of the present utility model are as follows: By cooperating the fixing plate with the vacuum suction pipe, the aluminum shell can be firmly adsorbed on the surface of the fixing plate. Through the rotation of the rotating plate, the aluminum shell is sleeved on the cleaning mold. Compressed air is introduced into the cleaning mold through the air guide pipe, and a certain pressure is formed inside the cleaning mold. The compressed air is discharged through the air guide through holes to blow the aluminum shell sleeved thereon, blowing out the metal burrs or impurities inside the aluminum shell. The blown-off metal burrs and impurities fall into the dust collection cover through the dust collection through holes on the dust collection plate. The dust collection cover and the dust collection suction pipe cooperate to collect the blown-off metal burrs and impurities and discharge them through the dust collection suction pipe, which can effectively clean the aluminum shell. After the aluminum shell is cleaned, it can be directly put into use, improving the production efficiency of the lithium battery. At the same time, it avoids the situation of easy occurrence of black explosion points during the welding of the aluminum shell and the top cover, reducing the probability of aluminum shell scrapping and the production cost of the lithium battery.

Detailed Embodiment

[0018] The present utility model will be further described below in conjunction with the description of the drawings and the detailed embodiment.

[0019] As Figures 1 to 6 shown, a cleaning device for the inner wall of an aluminum shell of a lithium battery includes a platform 1. A fixed seat 2 is provided in the middle of the platform 1. One side of the end of the fixed seat 2 is fixedly connected to a fixed column 3. A rotating plate 5 is rotatably connected to the fixed column 3 through a bearing 4. The end of the rotating plate 5 is fixedly connected to a fixing plate 6. Through holes 7 are opened at the four corners of the fixing plate 6. A vacuum suction pipe 8 is fixedly connected in the through holes 7. The end of the vacuum suction pipe 8 is fixedly connected to a suction cup 9. A cleaning mechanism is provided on one side of the fixed seat 2;

[0020] The cleaning mechanism includes a cleaning mold 10, an air guide pipe 11, a dust collection cover 12, a dust collection suction pipe 13 and a dust collection plate 14. A dust collection plate 14 fixedly connected to the platform 1 is provided on one side of the fixed seat 2. At least 8 dust collection through holes 15 are provided on the dust collection plate 14. A cleaning mold 10 is fixedly connected to the middle of the dust collection plate 14. The volume of the cleaning mold 10 is smaller than the volume of the aluminum shell of the lithium battery. The aluminum shell of the lithium battery can just be sleeved on the cleaning mold 10, and there is a certain gap between the aluminum shell of the lithium battery and the cleaning mold 10, which is convenient for compressed air to blow the inside of the aluminum shell for cleaning. A number of air guide through holes 16 are opened on the surface of the cleaning mold 10. A dust collection cover 12 fixedly connected to the platform 1 is provided at the bottom of the dust collection plate 14. A dust collection suction pipe 13 is fixedly connected to the dust collection cover 12. The air guide pipe 11 penetrates through the dust collection cover 12 and the dust collection plate 14 and is fixedly connected to the bottom of the cleaning mold 10.

[0021] For the convenience of connecting the vacuum suction pipes 8, they are aggregated into one, so that the vacuum suction pipes 8 cooperate with the fixing plate 6 to fix the aluminum shell of the lithium battery. Adjacent two vacuum suction pipes 8 are connected through a tee pipe 17 and are connected to an external vacuum pumping device.

[0022] In order to limit the aluminum shell of the lithium battery sleeved on the cleaning mold 10 and at the same time facilitate the collection of metal burrs and impurities cleaned off, a limiting plate 18 fixedly connected to the platform 1 is provided around the cleaning mold 10.

[0023] In order to facilitate the positioning of the aluminum shell of the lithium battery and at the same time facilitate the fixing of the aluminum shell of the lithium battery, a positioning baffle 19 is provided at one side end of the fixing plate 6.

[0024] The working process of the present utility model is as follows: First, start the external vacuum pumping device, place the aluminum shell of the lithium battery on one side of the positioning baffle 18, and ensure that the opening of the aluminum shell of the lithium battery faces the cleaning die 10 side. The vacuum suction pipe 8 cooperates with the suction cup 9 to adsorb the aluminum shell of the lithium battery on the upper surface of the fixing plate 6. Secondly, start the external compressed air device, continuously introduce compressed air into the cleaning die 10 through the air guide pipe 11, and discharge it through the air guide through hole 16. Under the action of the bearing 4, rotate the rotating plate 5 to sleeved the aluminum shell of the lithium battery on the cleaning die 10. The limiting plates 18 around the dust collecting plate 14 limit the aluminum shell of the lithium battery. Under the blowing and sweeping of the compressed air, the metal burrs and impurities in the aluminum shell of the lithium battery can be quickly blown out, and the inside of the aluminum shell of the lithium battery can be fully cleaned. The blown-off metal burrs and impurities fall on the dust collecting plate 14. Finally, under the combined action of the dust collecting cover 12 and the dust collecting suction pipe 13, the metal burrs and impurities fall into the dust collecting cover 12 through the dust collecting through hole 15 and are discharged through the dust collecting suction pipe 13. Repeating the above process can clean a whole batch of several aluminum shells of lithium batteries. After the aluminum shells are cleaned, they can be directly put into use, improving the production efficiency of lithium batteries, while avoiding the situation of easy occurrence of black explosion points during the welding of the aluminum shell and the top cover, reducing the probability of aluminum shell scrapping, and reducing the production cost of lithium batteries.

[0025] The above are only the preferred examples of the present utility model. The technical solutions of the present utility model are not limited thereto. It should be pointed out that for those of ordinary skill in the art, under the technical inspiration provided by the present utility model, as the common general knowledge in the art, other equivalent deformations and improvements can also be made, which should also be regarded as the protection scope of the present utility model.
