The provided vacuuming structure solves the problem of electrolyte being extracted during the vacuuming process of the battery in the prior art, achieving the technical effect of "less injection and less extraction" and reducing electrolyte waste; at the same time, it improves the phenomenon of battery appearance defects caused by electrolyte splashing due to the piercing of the gas bag by the piercing needle, and reduces the fatal defect risk of excessively thick sealing thickness caused by the crystallization and falling of splashed electrolyte.

[0003] However, when the above structure is used, the gas extracted from the battery is toxic, and direct discharge can easily cause pollution. Therefore, we propose a new gas extraction system for a battery cell double sealing machine. Utility Model Content

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the description of the textual part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a novel air extraction system for a battery cell second sealing machine, including a mounting plate 1 and a filter mechanism 3. An air extraction pump 2 is fixedly installed on the top of the mounting plate 1, and an air extraction pipe 4 is fixedly connected to the outer surface of the other side of the air extraction pump 2. One end of the air extraction pipe 4 is connected to the input end of the air extraction pump 2. A maintenance opening is provided on the front side of the air extraction pump 2, and a maintenance plate 5 is fixedly installed at the maintenance opening by bolts.

[0025] The filter mechanism 3 is located on one side of the air pump 2. The filter mechanism 3 includes a slide 31, a filter box 32, a slider 33, and a through groove 34. Two sets of slide 31 are provided on one side of the air pump 2. The filter box 32 is provided on one side of the mounting plate 1. Two sets of sliders 33 are fixedly installed on one side of the filter box 32. Both sets of sliders 33 are slidably installed in the corresponding slide 31. Two sets of through grooves 34 are provided on the top of the filter box 32.

[0026] The filtration mechanism 3 also includes a filter purification plate 35, an air outlet 36, and a limiting mechanism 37. The filter box 32 has two sets of filter purification plates 35 inside, and both sets of filter purification plates 35 are in contact with the inner wall of the corresponding through groove 34. At least two sets of air outlets 36 are opened through the other side of the filtration mechanism 3. The top of the filter box 32 is provided with a limiting mechanism 37. One side of the air pump 2 and one side of the filter box 32 are provided with a vent, which is connected to the output end of the air pump 2. At least two sets of mounting holes 6 are opened through the mounting plate 1. A set of handles 7 are fixedly installed on the front and rear outer surfaces of the filter box 32. After the gas in the battery cell is extracted through the filtration mechanism 3, it can be filtered and purified before being discharged, ensuring the environmental friendliness of the system. This solves the problem that the gas extracted from the battery in some existing structures is toxic gas, which is easy to cause pollution when discharged directly, thus improving the practicality of the system.

[0027] The limiting mechanism 37 includes a rotating block 371, a handle 372, a limiting block 373, a fixing block 374, an arc-shaped rod 375, and a spring 376. The rotating block 371 is rotatably mounted on the top of the filter box 32, and the handle 372 is fixedly mounted on the top of the rotating block 371. Two sets of limiting blocks 373 are fixedly mounted on the outer surface of the rotating block 371, and both sets of limiting blocks 373 are in contact with the top of the corresponding filter purification plate 35. The fixing block 374 is fixedly mounted on the top of the filter box 32, and an arc-shaped rod 375 is fixedly mounted on the fixing block 374. One set of limiting blocks 373 is movably sleeved on the arc-shaped rod 375, and a spring 376 is sleeved on the arc-shaped rod 375. The two ends of the spring 376 are fixedly connected to the fixing block 374 and the corresponding limiting block 373, respectively. Through the limiting mechanism 37, the filter purification plate 35 can be removed and replaced periodically to ensure the filtration and purification effect of the system on the gas, thus ensuring the system's performance and facilitating its promotion and use.

[0028] Working principle: When the air pump 2 is started, the gas from the battery cell is drawn into the filter box 32 through the air extraction pipe 4. After being filtered and purified by two sets of filter purification plates 35, the gas is discharged from the air outlet 36. When the filter purification plates 35 are replaced periodically, the handle 372 is turned to drive the rotating block 371 to rotate, which in turn causes the two sets of limit blocks 373 to rotate and no longer block the two sets of filter purification plates 35. One set of handles 372 slides on the arc rod 375 and compresses the spring 376. After the two sets of filter purification plates 35 are removed and replaced, the handle 372 is released. Under the rebound action of the spring 376, the two sets of limit blocks 373 return to their original position and block the two sets of filter purification plates 35. When the system needs to be repaired, the filter box 32 can be directly slid off from the slide groove 31 through the slider 33.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
