[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0023] Please refer to Figure 1-4 , the present application discloses a nail - driving device for transporting a sealing nail 1 to the liquid injection port of a battery 2, which includes: a sealing cavity 100 for accommodating the battery 2; a first channel 3 and a second channel 4 are opened on the sealing cavity 100, and both the first channel 3 and the second channel 4 communicate with the outside and the inside of the sealing cavity 100; a positioning mechanism 200 is arranged in the first channel 3; after the battery 2 is placed in the sealing cavity 100, the positioning mechanism 200 can communicate with the liquid injection port of the battery 2; a nail - driving mechanism 300 can communicate with the positioning mechanism 200 and then transport the sealing nail 1 to the liquid injection port of the battery 2; wherein, after the battery 2 is placed in the sealing cavity 100, the sealing cavity 100 can be evacuated through the second channel 4 to extract the gas inside the sealing cavity 100 and the battery 2.

[0024] Specifically, when the sealing cavity 100 is closed, a relatively airtight environment is formed inside it; in the sealing cavity 100, the air pressure inside the cavity and inside the battery 2 always remains the same. In this way, after the battery 2 is filled with liquid and placed in the sealing cavity 100, an external evacuation device (not shown) evacuates the sealing cavity 100 through the second channel 4, which can simultaneously extract the gas inside the sealing cavity 100 and the battery 2. While regulating the pressure inside the battery 2, it can avoid spraying liquid due to the relatively increased external air pressure squeezing the battery 2 shell.

[0025] After evacuating the battery 2, it is necessary to use the sealing nail 1 to block the liquid injection port of the battery 2; at this time, the nail - driving mechanism 300 communicates with the positioning mechanism 200, and transports the sealing nail 1 to the liquid injection port of the battery 2 through the positioning mechanism 200 and the first channel 3 to achieve sealing.

[0026] The sealed battery 2 is taken out of the sealing chamber 100. At this time, the external air pressure is greater than the air pressure inside the battery 2, and the shaping of the battery 2 can still be achieved. At the same time, since the liquid injection port of the battery 2 is blocked by the sealing nail 1, the electrolyte inside the battery 2 cannot overflow.

[0027] It should be added that to evacuate the sealing chamber 100, it is necessary to ensure that the inside of the sealing chamber 100 is relatively closed, so as to ensure the evacuation effect. However, both the first channel 3 and the second channel 4 communicate the outside and the inside of the sealing chamber 100. When the second channel 4 is connected to the pumping device, the first channel 3 also needs to be blocked to prevent gas from flowing through the first channel 3. That is to say, before evacuating the sealing chamber 100, it is necessary to make the nailing mechanism 300 communicate with the positioning mechanism 200 to block the first channel 3.

[0028] To facilitate the placement of the battery 2, the sealing chamber 100 includes: a receiving frame 110 with one end open for the battery 2 to enter and exit; a cover plate 120 for covering the open end of the receiving frame 110; and a cover plate driving assembly 130 capable of driving the cover plate 120 and the receiving frame 110 to move relative to each other, so that the cover plate 120 covers the open end of the receiving frame 110, or so that the cover plate 120 releases the covering of the open end of the receiving frame 110.

[0029] In a specific embodiment, referring to Figure 1 , the upper end of the receiving frame 110 is open, and the battery 2 after liquid injection can be placed into the receiving frame 110 through the opening. Subsequently, the cover plate driving assembly 130 drives the cover plate 120 and the receiving frame 110 to move towards each other, so that the cover plate 120 covers the open end of the receiving frame 110 to achieve sealing.

[0030] Among them, the cover plate driving assembly 130 can be provided with only one set of driving members, connected to the cover plate 120 to drive the cover plate 120 to move vertically, approaching or departing from the open end of the receiving frame 110; or connected to the receiving frame 110 to drive the receiving frame 110 to move vertically, approaching or departing from the cover plate 120. At this time, the battery 2 can be placed into the receiving frame 110 through the gap between the cover plate 120 and the receiving frame 110 after the cover plate 120 departs from the receiving frame 110. At this time, the cover plate driving assembly 130 can adopt driving members such as air cylinders and electric cylinders. Of course, the cover plate driving assembly 130 can also adopt a motor, with a double-threaded screw provided at the output end of the motor, and the cover plate 120 and the receiving frame 110 are respectively arranged on a section of the screw of the double-threaded screw. In this way, when the motor operates, it can drive the cover plate 120 and the receiving frame 110 to move relative to each other along their corresponding screws.

[0031] Alternatively, the cover plate driving assembly 130 may adopt two sets of driving members. One set of driving members can drive the cover plate 120 (or the accommodation frame 110) to move in the vertical direction, and the other set of driving members can drive the cover plate 120 (or the accommodation frame 110) to move in the horizontal direction. In this way, when it is necessary to open the sealing cavity 100 and insert or remove the battery 2, first, one set of driving members is used to drive the cover plate 120 (or the accommodation frame 110) to move away from each other in the vertical direction, so that the two are separated. Subsequently, the other set of driving members is used to drive the cover plate 120 (or the accommodation frame 110) to move away from each other in the horizontal direction, thereby exposing the open end of the accommodation frame 110, so that there is no projection of the cover plate 120 on the plane where the open end of the accommodation frame 110 is located, facilitating the insertion of the battery 2.

[0032] For example, referring to Figure 1 and Figure 2 , the cover plate driving assembly 130 includes a vertical driving assembly 131 and a horizontal driving assembly 132. The vertical driving assembly 131 includes a driving member (using a cylinder) and a guiding member (using a guide rod) arranged in the vertical direction. The output end of the driving member is connected to the accommodation frame 110, and the guiding member is connected to the accommodation frame 110 and slidably arranged in a linear bearing. When the driving member acts, it drives the accommodation frame 110 to drive the guiding member to move in the linear bearing, thereby enabling the accommodation frame 110 to approach or move away from the cover plate 120 in the vertical direction. The horizontal driving assembly 132 includes a driving member (using a motor, and the output end of the motor has a lead screw arranged in the horizontal direction) and a guiding member arranged in the horizontal direction (the direction perpendicular to the paper plane in the figure). The accommodation frame 110 is arranged at the output end of the vertical driving assembly 131, and the main body of the vertical driving assembly 131 is slidably arranged on the guiding member of the horizontal driving assembly 132. The driving member of the horizontal driving assembly 132 is connected to the vertical driving assembly 131 and can drive the vertical driving assembly 131 to move in the horizontal direction along the guiding member.

[0033] Alternatively, the cover plate 120 can be set to be able to flip relative to the accommodation frame 110. At this time, the cover plate driving assembly 130 can adopt a rotational driving member such as a motor or a rotary cylinder. When it is necessary to open the sealing cavity 100 and insert or remove the battery 2, the cover plate driving assembly 130 drives the cover plate 120 to flip and open the accommodation frame 110.

[0034] Furthermore, in order to seal the accommodation frame 110, a first sealing member 140 is provided on the bottom surface of the cover plate 120 (the side close to the accommodation frame 110) or on the upper surface of the open end of the accommodation frame 110. The first sealing member 140 can be made of a flexible material, such as rubber or polyurethane. When the cover plate 120 covers the open end of the accommodation frame 110, the first sealing member 140 is squeezed and deformed by the cover plate 120 and the accommodation frame 110, thereby blocking the gap between the two and achieving sealing.

[0035] By providing the first seal 140, it is also possible to prevent the cover plate 120 and the accommodation frame 110 from coming into rigid contact and damaging the structure of their contact surfaces. Specifically, as the cover plate 120 and the accommodation frame 110 move towards each other, the cover plate 120 gradually abuts against the first seal 140 and continues to move towards the accommodation frame 110. At this time, the first seal 140 is squeezed and deformed, thereby offsetting the travel of the continuous movement of the cover plate 120 and preventing the cover plate 120 from continuously pressing against the accommodation frame 110.

[0036] In other embodiments, the accommodation frame 110 may also have openings at its side ends (such as Figure 1 the front, rear, left, and right ends in the figure), and the battery 2 can be inserted into the accommodation frame 110 from the side ends. At this time, the arrangement of the cover plate 120 and the cover plate driving assembly 130 is similar to the case where the upper end of the accommodation frame 110 is open, and will not be elaborated here.

[0037] For the first channel 3 and the second channel 4, they can be provided on the same end face of the sealed cavity 100, or on different end faces. It is easy to conceive that when the sealed cavity 100 includes the accommodation frame 110 and the cover plate 120, the first channel 3 and the second channel 4 can be provided on the accommodation frame 110 or on the cover plate 120. The first channel 3 and the second channel 4 penetrate the end face on which they are provided and communicate the inside and outside of the sealed cavity 100.

[0038] In a specific embodiment, referring to Figure 1 , both the first channel 3 and the second channel 4 are provided on the cover plate 120; the second channel 4 communicates with a pumping device (not shown) inside and outside the sealed cavity 100; a positioning mechanism 200 is provided in the first channel 3. After the battery 2 is inserted into the accommodation frame 110 and the cover plate 120 covers the opening end of the accommodation frame 110, the positioning mechanism 200 communicates with the liquid injection port of the battery 2.

[0039] The position of the first channel 3 on the cover plate 120 is relatively fixed, and after the cover plate 120 covers the opening end of the accommodation frame 110, the position of the positioning mechanism 200 is also fixed. In order to ensure that after each battery 2 is inserted into the accommodation frame 110, its liquid injection port can accurately communicate with the positioning mechanism 200, a limiting assembly 600 is provided in the accommodation frame 110 to limit the position of the battery 2 in the accommodation frame 110. In this way, after a new battery 2 to be sealed is inserted into the accommodation frame 110, the limiting assembly 600 can limit or adjust the battery 2 to a preset position. As long as the configuration of the battery 2 remains certain, it can be ensured that the liquid injection ports of the batteries 2 at the same preset position are also at the same position, and this position is directly opposite to the positioning mechanism 200 and can communicate with the positioning mechanism 200.

[0040] Among them, the limiting component 600 can adopt a limiting block, and the limiting block encloses a semi-closed frame capable of accommodating the battery 2, thereby limiting the battery 2 therein. Alternatively, the limiting component 600 can adopt a suction cup, which can suck the battery 2 and thus limit the position of the battery 2. Or, the limiting component 600 can adopt a fixture. After the battery 2 is placed in the accommodating frame 110, the fixture can clamp the battery 2 and thus limit the position of the battery 2.

[0041] In a specific embodiment, referring to Figure 3 , the limiting component 600 includes a supporting member 610 for supporting the battery 2; a first clamping plate 620 disposed on one side of the supporting member 610; a second clamping plate 630 disposed on the other side of the supporting member 610; and a clamping driving member 640 capable of driving the first clamping plate 620 and the second clamping plate 630 to move relative to each other to clamp the battery 2 on the supporting member 610.

[0042] In this embodiment, the end face of the supporting member 610 for supporting the battery 2 can be recessed to form a groove capable of accommodating the battery 2; thus, when the battery 2 is placed in the sealing cavity 100, the battery 2 is located in the groove, and the supporting member 610 can first limit the general position of the battery 2. It is easy to understand that if the size of the groove exactly corresponds to the configuration of the battery 2, on the one hand, the wall surface of the groove will scratch the battery 2 when the battery 2 enters and exits, and on the other hand, it is not conducive to battery 2 type change and has low applicability; in summary, the groove will be larger than the battery 2 to facilitate the insertion and removal of the battery 2. After the battery 2 is placed in the groove, the clamping driving member 640 drives the first clamping plate 620 and the second clamping plate 630 to move towards each other to clamp the battery 2, thereby accurately limiting the position of the battery 2.

[0043] In a specific embodiment, referring to Figure 4 , the positioning mechanism 200 includes a positioning block 210, and the positioning block 210 has a through third channel 211; the third channel 211 communicates with the outside and the inside of the sealing cavity 100; after the sealing nail 1 enters the positioning block 210, it can flow to the liquid injection port of the battery 2 through the third channel 211.

[0044] For example, for the convenience of the flow of the sealing nail 1, the third channel 211 can be arranged to extend in the vertical direction; after the battery 2 to be sealed enters the sealing cavity 100 and the sealing cavity 100 is closed, the lower port of the third channel 211 communicates with the liquid injection port of the battery 2, and the upper port of the third channel 211 communicates with the nailing mechanism 300; the nailing mechanism 300 inputs the sealing nail 1 into the third channel 211; at this time, the sealing nail 1 falls along the third channel 211 and is finally squeezed into the liquid injection port.

[0045] It should be added that when the battery 2 to be sealed enters the sealing cavity 100 and the sealing cavity 100 is closed, the air extraction device needs to first evacuate the sealing cavity 100 through the second channel 4. At this time, in addition to evacuating the gas in the sealing cavity 100, the gas in the battery 2 also needs to be evacuated; that is to say, the positioning mechanism 200 cannot completely press against the liquid injection port of the battery 2, and there is a certain gap between the positioning mechanism 200 and the liquid injection port of the battery 2 to facilitate the outflow of the gas in the battery 2; at the same time, the gap between the positioning mechanism 200 and the liquid injection port of the battery 2 cannot be too large to avoid affecting the movement of the sealing nail 1 squeezing into the liquid injection port. Of course, when necessary, a lifting drive assembly can also be provided in the sealing cavity 100, which is connected to the battery 2 and can drive it to approach or move away from the positioning mechanism 200; thus, before vacuum extraction, the liquid injection port of the battery 2 is lower than the positioning mechanism 200, and after the vacuum extraction is completed, the lifting drive assembly can drive the battery 2 to move towards the positioning mechanism 200 until its liquid injection port abuts against the positioning mechanism 200.

[0046] For this reason, in one embodiment, the second channel 4 and the third channel 211 can be independent of each other; after the sealing cavity is closed, the third channel 211 is facing the liquid injection port of the battery 2, and the second channel 4 is arranged elsewhere. In other embodiments, the second channel 4 can also communicate with the third channel 211; after the sealing cavity 100 is closed, the third channel 211 is facing the liquid injection port of the battery 2, and the second channel 4 also communicates with the inside of the sealing cavity 100 and the liquid injection port of the battery 2 via the third channel 211, and air extraction and nail driving can also be achieved.

[0047] In addition, the nail driving device provided in the present application further includes a stop mechanism 500, which can block the third channel 211, thereby preventing the sealing nail 1 from passing through the third channel 211.

[0048] It should be explained that the positioning mechanism 200 includes an output end that can communicate with the liquid injection port of the battery 2 and an input end that can communicate with the nail driving mechanism 300; that is to say, the output end of the third channel 211 communicates with the liquid injection port of the battery 2, and the input end of the third channel 211 will communicate with the nail driving mechanism 300. During vacuum extraction, it is necessary to first block the input end of the third channel 211 to avoid air flow; for this reason, before vacuum extraction, it is necessary to first connect the nail driving mechanism 300 to the third channel 211 to achieve relative sealing of the third channel 211.

[0049] In one embodiment, the nail driving mechanism 300 feeds the sealing nail 1 by blowing air, and uses air pressure to blow the sealing nail 1 into the third channel 211. At this time, it is necessary to first send the sealing nail 1 into the third channel 211 and then perform vacuum extraction to avoid the gas blown in during feeding interfering with the vacuum extraction. Specifically, after the sealing nail 1 is sent into the third channel 211, the nail driving mechanism 300 stops blowing air, and then the air extraction device performs vacuum extraction.

[0050] In summary, before vacuum pumping, the sealing nail 1 has entered the third channel 211. At this time, if the sealing nail 1 directly falls towards the liquid injection port of the battery 2, it may block the liquid injection port to a certain extent, thereby affecting the evacuation of the interior of the battery 2. Therefore, a stop mechanism 500 needs to be provided to first support the sealing nail 1 to prevent it from falling. After the vacuum pumping action is completed, the stop mechanism 500 cancels the support for the sealing nail 1, enabling the sealing nail 1 to move downward and block the liquid injection port.

[0051] It should be added that in order to facilitate the movement of the sealing nail 1 towards the liquid injection port, the diameter of the third channel 211 is slightly larger than the volume of the sealing nail 1. While allowing the sealing nail 1 to pass smoothly, it does not allow the sealing nail 1 to tilt or flip in the third channel 211, so as to ensure that after the sealing nail 1 enters the third channel 211 with its head downwards, it still approaches the liquid injection port of the battery 2 with its head downwards and finally realizes the sealing.

[0052] To facilitate the setting of the stop mechanism 500, the stop mechanism 500 can be provided outside the sealing cavity 100. For example, referring to Figure 1 , when the positioning mechanism 200 is provided on the cover plate 120, the stop mechanism 500 is also provided on the cover plate 120. At this time, the stop assembly 500 includes a stop member 510 and a stop driving member 520. The stop driving member 520 is connected to the stop member 510 and can drive the stop member 510 to extend into or out of the third channel 211.

[0053] Specifically, the stop member 510 can be a long rod. The stop member 510 passes through the positioning block 210 and can extend into the third channel 211. When the sealing nail 1 is loaded, at least a part of the stop member 510 is in the third channel 211 to prevent the sealing nail 1 from passing through. After the vacuum pumping is completed, the stop driving member 520 drives the stop member 510 to leave the third channel 211 to facilitate the passage of the sealing nail 1. Of course, to avoid damaging the vacuum pumping effect, the stop driving member 520 does not drive the stop member 510 to completely leave the positioning block 210. After the stop member 510 leaves the third channel 211, it still stays in the positioning block 210.

[0054] Furthermore, the nail driving device further includes a detection member 5. The detection end of the detection member 5 faces the third channel 211 and can detect the sealing nail 1 in the third channel 211.

[0055] In a specific embodiment, the detection member 5 can be a photoelectric sensor. Its detection end passes through the positioning block 210 and is above the stop member 510, that is, at the position where the sealing nail 1 will stay when the stop member 510 blocks the sealing nail 1. When there is a sealing nail 1, the sealing nail 1 will block the signal of the detection member 5. The detection member 5 transmits the signal to the control system, and the control system thereby knows that the sealing nail 1 in the third channel 211 is blocked by the stop assembly 500. Subsequently, the control system can control the evacuation device to evacuate the sealing cavity 100.

[0056] By providing the detection member 5, it can be ensured that the air in the sealing cavity 100 is evacuated only after the sealing nail 1 is fed into the nailing device, thereby avoiding the interference of the feeding of the sealing nail 1 with the vacuum pumping effect and ensuring the accurate use of the equipment.

[0057] In other embodiments, the detection member 5 can also be provided at the input end or the output end of the third channel 211, as long as it can detect whether there is a sealing nail 1 in the third channel 211.

[0058] To enable the sealing nail 1 to block the liquid injection port of the battery 2, it is difficult to achieve only by the self-weight of the sealing nail 1 and the impact force when it falls into the liquid injection port. Therefore, after the sealing nail 1 is input into the positioning mechanism 200, other mechanisms need to be provided to extend into the positioning mechanism 200 and forcefully press the sealing nail 1 into the liquid injection port. For this purpose, the nailing mechanism 300 includes: a nail feeding assembly 310 capable of feeding the sealing nail 1 to the positioning mechanism 200; a nail pressing assembly 320 capable of extending into the positioning mechanism 200 and pressing the sealing nail 1 towards the liquid injection port of the battery 2.

[0059] In one embodiment, the nail feeding assembly 310 and the nail pressing assembly 320 can be provided as one body (not shown). Specifically, the nail feeding assembly 310 includes a nail feeding block, and a through fourth channel is provided in the nail feeding block; the nail pressing assembly 320 includes a nail pressing block, and a through fifth channel is provided in the nail pressing block; at this time, the nail feeding block and the nail pressing block are connected together, and the fourth channel and the fifth channel are communicated. To achieve nail pressing, the nail pressing assembly 320 further includes a nail pressing member and a nail pressing driving member, the nail pressing driving member is connected to the nail pressing member and can drive the nail pressing member to move along the fifth channel; the nail pressing member is a long rod and can extend into the third channel 211 along the fifth channel to push the sealing nail 1; thus, the fifth channel is parallel to the third channel 211 and extends linearly. When the nailing mechanism 300 is communicated with the positioning mechanism 200, the fifth channel is communicated with the third channel 211. Therefore, the fourth channel can only be inclined and arranged on one side of the fifth channel and communicated with the fifth channel.

[0060] In this embodiment, one end of the fourth channel is communicated with an external sealing nail feeding mechanism (not shown), and the other end is communicated with the fifth channel; one end of the fifth channel is communicated with the third channel 211, and the nail pressing member extends from the other end of the fifth channel. During feeding, the sealing nail feeding mechanism inputs the sealing nail 1 into the fourth channel, the sealing nail 1 flows from the fourth channel into the fifth channel, then into the third channel 211, and finally is blocked in the third channel 211 by the stop mechanism 500; after the vacuum pumping is completed, the stop mechanism 500 releases the block on the third channel 211, and the sealing nail 1 flows along the third channel 211 towards the liquid injection port of the battery 2; the nail pressing driving member drives the nail pressing member to enter the third channel 211 along the fifth channel to press against the sealing nail 1, and finally presses the sealing nail 1 into the liquid injection port to achieve sealing.

[0061] In another embodiment, the nail feeding assembly 310 and the nail pressing assembly 320 are independently provided. Figure 1 and Figure 2 The nail feeding assembly 310 includes a nail feeding block 311, and a fourth channel 312 is provided in the nail feeding block 311, and the fourth channel 312 is connected to the sealing nail feeding mechanism; when the nail feeding block 311 is connected to the positioning mechanism 200, the fourth channel 312 is connected to the third channel 211, and the sealing nail feeding mechanism can transport the sealing nail 1 to the liquid filling port of the battery 2 through the fourth channel 312 and the third channel 211.

[0062] In a specific embodiment, referring to Figure 2 , the fourth channel 312 is also extended in the vertical direction, so that when the nail feeding assembly 310 is connected with the positioning mechanism 200, the fourth channel 312 is connected with the third channel 211 to form a vertical circulation channel; at this time, the diameters of the fourth channel 312 and the third channel 211 are set to be slightly larger than the volume of the sealing nail 1, so that the fourth channel 312 and the third channel 211 allow the sealing nail 1 to pass smoothly while not allowing the sealing nail 1 to tilt or flip in the channel, thereby ensuring that the sealing nail 1 is in a stable state during the transportation process; the sealing nail 1 can smoothly pass through the fourth channel 312 and the third channel 211 and flow to the injection port of the battery 2, avoiding accidents such as nail jamming when the channel turns.

[0063] Correspondingly, the nail pressing assembly 320 includes: a nail pressing member 321 , which can extend into the positioning mechanism 200 ; and a nail pressing driving member 322 , which is connected to the nail pressing member 321 and can drive the nail pressing member 321 to move closer to or away from the positioning mechanism 200 .

[0064] The pressure nail member 321 can be a long rod that can be inserted into the third channel 211, and can move toward the battery 2 along the third channel 211 under the drive of the pressure nail driving member 322, thereby pushing the sealing nail 1 in the third channel 211 to move toward the liquid injection port, and finally pushing the sealing nail 1 to block the liquid injection port and achieve sealing. The pressure nail driving member 322 can be a driving member such as a cylinder or an electric cylinder.

[0065] It is easy to understand that in order to ensure that the pressure nail member 321 accurately extends into the third channel 211, it is necessary to ensure that when the pressure nail assembly 320 is connected to the positioning mechanism 200, the pressure nail member 321 is directly opposite to the input end of the third channel 211. In order to improve the accuracy of the position of the pressure nail member 321, the pressure nail assembly 320 also includes a pressure nail block 323, and the pressure nail block 323 has a fifth channel 324 that passes through; the pressure nail member 321 is always partially in the fifth channel 324; when the pressure nail block 323 is connected to the positioning mechanism 200, the fifth channel 324 is connected to the third channel 211, and the pressure nail member 321 can extend into the third channel 211 through the fifth channel 324.

[0066] In a specific embodiment, referring toFigure 2 The fifth channel 324 also extends vertically. In this way, when the nail pressing assembly 320 is connected to the positioning mechanism 200, the fifth channel 324 communicates with the third channel 211 to form a vertically extending flow channel. The nail pressing member 321 is always located in the fifth channel 324, and the fifth channel 324 restricts the position and movement direction of the nail pressing member 321. On the one hand, as long as the nail pressing assembly 320 is connected to the positioning mechanism 200, it can be ensured that the nail pressing member 321 is facing the third channel 211. On the other hand, when the nail pressing driving member 322 drives the nail pressing member 321 to move, the movement direction of the nail pressing member 321 is restricted by the fifth channel 324, and the fifth channel 324 guides the nail pressing member 321 to move only along the extension direction of its channel, so that the nail pressing member 321 can accurately enter the third channel 211.

[0067] At this time, the diameters of the fifth channel 324 and the third channel 211 are set to be slightly larger than the volume of the part of the nail pressing member 321 extending into the third channel 211. In this way, while allowing the nail pressing member 321 to move, the fifth channel 324 and the third channel 211 can also restrict the movement direction of the nail pressing member 321, thereby ensuring the stable state of the nail pressing member 321 during movement.

[0068] When the nail feeding assembly 310 and the nail pressing assembly 320 are independently arranged, to feed the nail, the nail pressing assembly 320 needs to be away from the positioning mechanism 200, and the nail feeding assembly 310 is connected to the positioning mechanism 200. After the sealing nail 1 is in place, the nail feeding assembly 310 needs to be away from the positioning mechanism 200 to facilitate the connection between the nail pressing assembly 320 and the positioning mechanism 200. For this reason, the nail driving device provided in the present application further includes a translation assembly 600, which connects the nail feeding assembly 310 and the nail pressing assembly 320 and can drive the nail feeding assembly 310 and the nail pressing assembly 320 to move, so that when one of the nail feeding assembly 310 and the nail pressing assembly 320 is connected to the positioning mechanism 200, the other is away from the positioning mechanism 200.

[0069] Among them, the translation assembly 600 can be provided with only one set of driving members, which are simultaneously connected to the nail feeding assembly 310 and the nail pressing assembly 320. At this time, the nail feeding assembly 310 and the nail pressing assembly 320 are arranged side by side at the output end of the translation assembly 600. When feeding the nail, the translation assembly 600 drives the nail feeding assembly 310 to be connected to the positioning mechanism 200. When pressing the nail, the translation assembly 600 acts in the reverse direction, driving the nail feeding assembly 310 away from the positioning mechanism 200 and the nail pressing assembly 320 to be connected to the positioning mechanism 200.

[0070] Alternatively, the translation assembly 600 can be provided with two sets of driving members, which are respectively connected to the nail feeding assembly 310 and the nail pressing assembly 320, so as to drive the connected components to approach or away from the positioning mechanism 200 as needed.

[0071] The translation component 600 can adopt driving components such as air cylinders, electric cylinders, and linear modules.

[0072] Further, when the translation component 600 drives the nail feeding component 310 and the nail pressing component 320 to translate, if the nail feeding component 310 and the nail pressing component 320 can directly abut against the connection positioning mechanism 200, the contact surface between the nail feeding component 310 (or the nail pressing component 320) and the positioning mechanism 200 will be worn, affecting their structures. Therefore, the nail driving device provided in this application further includes a lifting component 700, which is connected to the nail feeding component 310 and / or the nail pressing component 320 and can drive the nail feeding component 310 or the nail pressing component 320 to approach and abut against the positioning mechanism 200.

[0073] Among them, the lifting component 700 can be provided with only one set of driving components, which are simultaneously connected to the nail feeding component 310 and the nail pressing component 320. In the initial state, the nail feeding component 310 and the nail pressing component 320 are suspended above the positioning mechanism 200; when feeding nails, the translation component 600 first drives the nail feeding component 310 to face the positioning mechanism 200, and then the lifting component 700 drives them to descend, so that the nail feeding component 310 is docked with the positioning component 200 to achieve connection; since the positioning mechanism 200 has a part protruding from the sealing cavity 100, when the nail feeding component 310 is docked with the positioning component 200, the nail pressing component 320 is suspended above the sealing cavity 100; when pressing nails, the translation component 600 drives the nail pressing component 320 to face the positioning mechanism 200, and then the lifting component 700 drives them to descend, so that the nail pressing component 320 is docked with the positioning component 200 to achieve connection.

[0074] Alternatively, the lifting component 700 can also be provided with two sets of driving components, which are respectively connected to the nail feeding component 310 and the nail pressing component 320, so as to drive the connected components to abut against or move away from the positioning mechanism 200 as needed.

[0075] The lifting component 700 can adopt driving components such as air cylinders, electric cylinders, and linear modules.

[0076] The following briefly describes the movement process of the nail driving device in an embodiment:

[0079] The positioning mechanism 200 is opposite to the liquid injection port of the battery 2;

[0080] The translation component 600 drives the nail feeding component 310 to face the positioning mechanism 200;

[0082] The sealing nail feeding mechanism conveys the sealing nails 1 to the nail feeding assembly 310;

[0083] The sealing nails 1 flow into the third channel 211 through the fourth channel 312, are blocked by the stop mechanism 500, and are suspended above the liquid injection port of the battery 2;

[0084] The lifting assembly 700 drives the nail feeding assembly 310 to rise, the translation assembly 600 drives the nail feeding assembly 310 away from the positioning assembly 200, and further drives the nail pressing assembly 320 to face the positioning mechanism 200;

[0085] The lifting assembly 700 drives the nail pressing assembly 320 to descend, so that the nail pressing assembly 320 docks with the positioning assembly 200 to achieve communication;

[0086] The air extraction device evacuates the sealing cavity 100 and the inside of the battery 2 through the second channel 4;

[0087] The stop mechanism 500 releases the block on the third channel 211, and the sealing nails 1 fall freely;

[0088] The nail pressing driving member 322 drives the nail pressing member 321 to extend into the third channel 211 through the fifth channel 324, presses against the sealing nails 1, and presses the sealing nails 1 into the liquid injection port of the battery 2 to achieve sealing. Thus, the nail driving for one battery 2 is completed.
