Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0035] The utility model provides a battery sealing device, referring to Figure 1 The battery sealing device 100 includes a mobile fixture 1, a feeding mechanism 2 and a nail insertion mechanism 3. The mobile fixture 1 is used to clamp or release the battery and to transport the battery to the bottom of the nail insertion mechanism 3. The feeding mechanism 2 is connected to the nail insertion mechanism 3 and is used to transport the sealing nails to the nail insertion mechanism 3. The nail insertion mechanism 3 includes a frame 31 and a nail insertion module 32. The nail insertion module 32 is installed on the frame 31 and is used to insert the sealing nail into the battery injection port to seal the battery.

[0036] Based on the above-mentioned scheme, the mobile fixture 1 clamps and fixes the battery, and transports the battery to the processing station, which is the position corresponding to the nail module 32, so that the nail module 32 can insert the sealing nail into the battery filling port from the top of the battery, and the feeding mechanism 2 can automatically feed the sealing nails quickly and neatly, and continuously feed the nail module 32, so that the entire nail sealing process is uninterrupted, the production rhythm is compact, and the production efficiency of the sealed battery filling port can be greatly improved, and the production quality of the sealed battery can be improved.

[0037] Among them, the sealing nail can be a glue nail or other sealing structure that can seal the battery filling port. In the embodiment of the present application, the sealing nail is a glue nail. This is only an example and does not limit the type of sealing nail.

[0038] Reference Figures 1 to 6 The nail insertion module 32 includes a first driving component 321, a nail pressing member 322 and a material receiving member 323. The first driving component 321 includes a mounting plate 3211 and a first driving member 3212. The mounting plate 3211 is connected to the frame 31. The first driving member 3212 is connected to the mounting plate 3211. The nail pressing member 322 is connected to the first driving member 3212. The first driving member 3212 is used to drive the nail pressing member 322 to move. The material receiving member 323 is connected to the mounting plate 3211. The material receiving member 323 is connected to the pipeline of the feeding mechanism 2 and is used to receive and place the sealing nails delivered by the feeding mechanism 2. The nail pressing member 322 is used to press the sealing nails on the material receiving member 323 into the liquid filling port of the battery.

[0039] The receiving piece 323 is used to stably receive the sealing nails delivered by the feeding mechanism 2 to ensure the normal supply of the sealing nails and avoid failure of the incoming materials or jamming of the sealing nails. According to the height of the battery, the receiving piece 323 can be moved to a height position corresponding to the battery filling port. The first driving piece 3212 drives the pressing nail piece 322 to move and press the sealing nail from the receiving piece 323 to the battery until the sealing nail is inserted into the battery filling port.

[0040] With such arrangement, the first driving member 3212, the nail pressing member 322 and the material receiving member 323 are used to realize automatic nail insertion, and the nail insertion has good stability and is time-saving, thereby greatly improving the production efficiency of sealing the battery filling port.

[0041] Continue to refer to Figures 1 to 6 The material receiving piece 323 is provided with a material receiving channel 3231, a pressing nail channel 3232 and an accommodating chamber 3233. The material receiving channel 3231 and the pressing nail channel 3232 are both connected to the accommodating chamber 3233. The material receiving channel 3231 is connected to the feeding mechanism 2. The pressing nail channel 3232 is for the pressing nail piece 322 to pass through. The accommodating chamber 3233 is for the sealing nail to be placed. The outer wall of the sealing nail is in abutment contact with the cavity wall of the accommodating chamber 3233. The end of the accommodating chamber 3233 away from the pressing nail piece 322 is open to form a discharge port 3234. The discharge port 3234 is correspondingly arranged with the pressing nail channel 3232.

[0042] The material receiving channel 3231 is used to connect with the feeding mechanism 2 to facilitate the transportation of the sealing nail, and the cavity wall of the accommodating cavity 3233 is used to abut against the outside of the sealing nail. As long as the two can abut against each other, the sealing nail can be prevented from directly sliding out of the discharge port 3234. This ensures that the sealing nail can be placed on the material receiving member 323, so that the pressing nail member 322 can push the sealing nail toward the battery along the direction specified by the pressing nail channel 3232 under the action of the first driving member 3212, and insert the sealing nail into the battery filling port.

[0043] Such an arrangement can ensure both the production efficiency and the production quality of the sealed battery, thereby better improving the performance of the battery sealing device 100 .

[0044] The pressure nail component 322 may be a pressure rod or an axle structure, or other structural components that can push the sealing nail to move, as long as the sealing nail can be inserted into the battery filling port, and no limitation is made here.

[0045] The nail inserting module 32 further includes a guide member 324 connected to the mounting plate 3211 . The nail pressing member 322 is provided with a first guide portion 3221 , and the guide member 324 is provided with a second guide portion 3241 . The first guide portion 3221 and the second guide portion 3241 cooperate to guide the movement of the nail pressing member 322 .

[0046] Through the guiding cooperation of the first guide part 3221 and the second guide part 3241, the shaking or jamming of the pressure nail member 322 during movement is effectively avoided, the smoothness of the movement of the pressure nail member 322 is improved, and the pressure nail member 322 is helped to stably insert the sealing nail into the battery filling port, thereby improving the effect of sealing the battery.

[0047] The guide member 324 may be a guide block, which is fixedly mounted on the mounting plate 3211 , the first guide portion 3221 may be a guide column or other shaft structure, and the second guide portion 3241 may be a guide hole or a guide notch.

[0049] The second driving assembly 325 can drive the first driving assembly 321, the pressing nail piece 322 and the material receiving piece 323 to move as a whole, so that the height of the material receiving piece 323 can be adjusted according to the height of the battery or the on-site processing environment to adapt to batteries of different specifications and sizes, thereby improving the applicability of the battery sealing device 100. Moreover, the first driving assembly 321 and the second driving assembly 325 can realize the dual driving function of the battery sealing device 100, thereby improving the processing accuracy of the sealed battery and better improving the production quality of the sealed battery.

[0053] There are multiple groups of nail modules 32, all of which are connected to the frame 31 and arranged side by side. In this way, multiple groups of nail modules 32 can be used to achieve large-scale sealed batteries, further improving the production efficiency of sealed batteries, thereby increasing production capacity.

[0054] Continue to refer to Figures 1 to 6 The battery sealing device 100 further includes a detection module 4, which is connected to the frame 31 and is disposed opposite to the nail module 32. The detection module 4 is used to detect the sealing quality of the battery filling port.

[0055] After the nail module 32 completes sealing the battery, the battery is moved to the bottom of the detection module 4 by the mobile fixture 1, so that the detection module 4 can detect the quality of the battery nails or whether the battery is sealed. This can effectively avoid the situation where the battery has missing nails and causes defective batteries, thereby improving the reliability of battery processing.

[0056] There may be multiple detection modules 4 , and multiple detection modules 4 are correspondingly arranged with multiple nail insertion modules 32 , so that a large number of batteries can be detected, thereby improving the production efficiency of the battery sealing device 100 .

[0057] The detection module 4 may be a photoelectric sensor, such as a laser sensor; or, the detection module 4 may be a contact sensor, such as a mechanical contact sensor.

[0058] It is understandable that the detection module 4 can also be an industrial camera or other electronic components capable of detecting whether the battery is inserted into the sealing nail, which will not be described in detail here.
