Technical Field

[0001] The utility model relates to an energy storage battery box assembly air tightness detection device. Background Art

[0002] The energy storage battery box assembly airtightness detection device is mainly used to detect the leakage value of the energy storage battery box. When assembling the energy storage battery box, the internal airtightness of the battery must be ensured to prevent external impurities and external air from mixing with the internal gas of the battery, so as to ensure the life of the battery and improve the safety of the battery.

[0003] However, the existing energy storage battery case assembly airtightness detection device often needs to be cumbersomely adjusted for battery cases of different models and sizes, which not only increases the complexity of the equipment, but also greatly reduces the detection efficiency. At the same time, due to the diversity of battery case products, there is a phenomenon of "single model for single use" and poor compatibility, especially when the battery case has a variety of shapes and sizes. The cycle time of adding a set of airtightness detection devices is long and the cost investment is large. In view of this, the utility model proposes an energy storage battery case assembly airtightness detection device to solve the above problems. Utility Model Content

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Embodiment:

[0027] As Figure 1-5 shown, this embodiment proposes an airtightness detection device for an energy storage battery box body assembly, which is used to detect the battery box body 60, including a fixing plate 10, and a sealing strip 50 is further arranged on the fixing plate 10;

[0028] The sealing strip 50 is in a "return" shape, the battery box body 60 is provided with a flange connection surface 61, the sealing strip 50 is adapted to the flange connection surface 61, and a plurality of groups of filling blocks 20 are further arranged on the fixing plate 10. The sealing strip 50 is sleeved outside the plurality of groups of filling blocks 20. The plurality of groups of filling blocks 20 are combined to form the cavity shape of the battery box body 60. A plurality of groups of positioning components 30 are further arranged on the fixing plate 10. The positioning components 30 are in contact with the battery box body 60, so that the battery box body 60 is closely attached to the sealing strip 50. Two air inlet pipes 40 are arranged on the fixing plate 10, and the air inlet pipes 40 guide gas into the cavity of the battery box body 60.

[0029] In this case, a valve for opening and closing is arranged on the air inlet pipe 40.

[0030] In this embodiment, when the battery box 60 is tested for sealing, a filling block 20 that is compatible with the cavity of the battery box 60 is installed on the surface of the fixing plate 10 to reduce the inflation time. At the same time, the flange connection surface 61 of the battery box 60 is aligned with the sealing strip 50, and the battery box 60 is placed on the sealing strip 50. It is detected whether the flange connection surface 61 is completely placed on the sealing strip 50. Then, an air pressure detector is connected to one group of air intake pipes 40, and another group of air intake pipes 40 is connected to the air outlet pipe of the air supply equipment (such as an air compressor). At the same time, multiple groups of positioning components 30 are operated to position the battery box 60 on the sealing strip 50 to complete the sealing process. Then, the air supply equipment is operated and the air intake pipe 40 connected to the air pressure detector is closed. Valve, introduce gas into the inner cavity of the battery box 60 through the air intake pipe 40, and close the valve on the air intake pipe 40 connected to the air supply device. After a period of time, open the valve on the air intake pipe 40 connected to the air pressure detector, and use the air pressure detector to detect the gas pressure inside the battery box 60. When the leakage value is less than or equal to the set value, it means it is qualified, and when the leakage value is greater than the set value, it means it is unqualified. The set value is set according to the actual situation. If it is unqualified, apply water on the surface to find bubbles and perform maintenance. After the detection is completed, the positioning component 30 releases the restriction on the battery box 60, and the battery box 60 is lifted from the fixed plate 10 by equipment such as a gantry crane, and the above process is repeated to detect the next group of battery boxes 60;

[0031] Of course, when performing sealing tests on different battery boxes 60, the positions of the multiple positioning components 30 are adjusted, and the sealing strips 50 adapted to the battery boxes 60 are installed;

[0032] The filling block 20 is designed to accurately adapt to the internal cavity shape of the battery case 60. Such adaptation not only helps the battery case 60 to maintain good contact with the sealing strip 50 on the fixed plate 10 during the detection process, but also can quickly and accurately position the battery case 60 and align it with the sealing strip 50, reducing the time for device setup and adjustment, thereby improving the overall efficiency of the detection. At the same time, the presence of the filling block 20 can reduce the cavity volume inside the battery case 60, thereby reducing the required inflation time. This design effectively shortens the entire airtightness detection cycle and improves the efficiency of the detection process. Moreover, by replacing filling blocks 20 and sealing strips 50 of different shapes or sizes, the device can adapt to battery cases 60 of different models and sizes. This flexibility means that the device is not limited to a specific model of battery case 60, but can be widely used in airtightness detection of various battery cases 60, thereby enhancing the versatility and application range of the equipment.

[0043] The pressing plate 35 is disposed on a mounting rod 36 .

[0044] In this embodiment, the corner cylinder 32 can be centrally controlled by a PLC control system. When the battery box 60 is pressed down to position, the corner cylinder 32 operates to drive the extension block 33, the mounting rod 36 and the pressure plate 35 to rotate and descend, so that the pressure plate 35 is placed on the surface of the battery box 60, and the battery box 60 is pressed tightly, so that the battery box 60 is pressed against the sealing strip 50 to keep the cavity of the battery box 60 in a sealed state for sealing detection.
