[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on August 9, 2023, with application number 202322127421.8 and application name “Piercing Mechanism and Packaging Machine”, all contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of battery processing technology, and in particular to a puncture mechanism and a packaging machine. Background Art

[0004] The production process of soft-pack batteries requires several steps, including liquid injection, formation, gas extraction, and packaging. Since soft-pack batteries generate gas during the formation process, the air bag of the soft-pack battery must be punctured after formation is complete to extract the gas before repackaging.

[0005] Existing packaging machines, due to the fixed position of the bayonet, are unable to puncture the air pockets of soft-pack batteries of different sizes. For example, to puncture the air pockets of large soft-pack batteries, the bayonet is positioned high. When processing the air pockets of small soft-pack batteries, the bayonet is positioned higher than the air pocket, making it impossible to puncture the air pocket. Therefore, currently, different packaging machines are required to package soft-pack batteries of different sizes, resulting in high packaging costs.

[0006] Summary of the Invention

[0007] Based on this, it is necessary to provide a puncture mechanism and packaging machine that can be applied to soft-pack batteries of different sizes and has low packaging costs in order to address the problem that existing packaging machines are not suitable for soft-pack batteries of different sizes, resulting in high packaging costs.

[0012] When using this puncture mechanism, when puncturing a larger airbag, the puncture element moves away from the clamping mechanism, and then punctures the airbag. When puncturing a smaller airbag, the puncture element moves closer to the clamping mechanism, moving toward the airbag, and then puncturing the airbag. In this way, the puncture mechanism can be applied to airbags of different sizes for soft-pack batteries, effectively reducing packaging costs.

[0041] As shown in Figure 1, one embodiment of the present application provides a packaging machine comprising a top cover 100, a lower chamber 200, and a middle chamber 300. The lower chamber 300 includes a clamping mechanism, the middle chamber 200 includes a packaging mechanism, and the top cover 100 includes a puncturing mechanism. The clamping mechanism is used to clamp the clamped object, the packaging mechanism is used to package the clamped object, and the puncturing mechanism is used to puncture the clamped object.

[0042] It should be noted that, in this application, the clamped part is an air bag 400 of a soft-pack battery (see FIG5 ). For ease of understanding, the following description will take the air bag 400 as an example.

[0043] Furthermore, the lower cavity 200, the middle cavity 300 and the top cover 100 are arranged in sequence along the vertical direction, and the middle cavity 300 and the top cover 100 can both be moved along the vertical direction, so that the lower cavity 200, the middle cavity 300 and the top cover 100 are separated from each other, making it convenient to maintain the clamping mechanism in the lower cavity 200 and the packaging mechanism in the middle cavity 300.

[0044] 2 to 4 , in some embodiments, the puncturing mechanism includes a carrier module 12 and a puncturing member 13. The puncturing member 13 is disposed on the carrier module 12 and is used to puncture the air bag 400 on the clamping mechanism.

[0045] The piercing member 13 is constructed to be controllably move closer to or farther from the clamping mechanism so as to be suitable for piercing clamps of different sizes.

[0046] It should be noted that, in this embodiment, the piercing member 13 is a bayonet.

[0047] The first direction is the up-down direction in FIG. 1 and FIG. 4 .

[0048] Using the aforementioned puncturing mechanism, when puncturing a larger airbag 400, the puncturing member 13 moves away from the clamping mechanism, and the airbag 400 is then punctured by the puncturing member 13. When puncturing a smaller airbag 400, the puncturing member 13 moves closer to the clamping mechanism, moving toward the airbag 400, and then puncturing the airbag 400. In this way, the puncturing mechanism can be applied to airbags 400 of different sizes for soft-pack batteries, effectively reducing packaging costs.

[0049] In some embodiments, the puncture mechanism further includes a mounting plate 110. The carrier module 12 is disposed on the mounting plate 110 and is configured to be controllably movable relative to the mounting plate 110 to drive the puncture member 13 toward or away from the clamping mechanism during movement.

[0050] Specifically, the carrying module 12 is configured to be controllably movable relative to the mounting plate 110 along a first direction, wherein the first direction is the up-down direction in FIG1 and FIG4 , and is a vertical direction in actual application.

[0051] In some embodiments, the puncture mechanism further includes a mounting seat 14. The mounting seat 14 is configured to be controllably moved close to or away from the clamping mechanism, and the carrying module 12 is disposed on the mounting seat 14.

[0052] Furthermore, the puncturing mechanism includes multiple sets of carrier modules 12 and multiple puncturing elements 13. The multiple sets of carrier modules 12 are all arranged on the mounting base 14, and each carrier module 12 is provided with a puncturing element 13 to puncture multiple air bags 400 at the same time.

[0053] Specifically, in the embodiment shown in FIG. 2 , the carrying modules 12 include four groups, and the four groups of carrying modules 12 are arranged at intervals along a second direction different from the first direction.

[0054] Specifically, the first direction is perpendicular to the second direction, and the second direction is the left-right direction in FIG. 2 and FIG. 3 , and the second direction is the horizontal direction in actual application.

[0055] In some embodiments, the puncturing mechanism further includes an adjustment structure disposed on the mounting plate 110 and connected to the carrier module 12. The adjustment structure is used to drive the carrier module 12 to move so as to move the puncturing member 13 toward or away from the clamping mechanism.

[0056] Furthermore, the adjustment structure is connected to the mounting base 14 to drive the mounting base 14 to move along the first direction, thereby driving the multiple groups of carrying modules 12 to move along the first direction.

[0057] Optionally, the adjusting structure is a cylinder or other driving structure capable of driving the mounting base 14 to move.

[0058] In some embodiments, the piercing member 13 is configured to be controllably extended or retracted from the carrier module 12. When the piercing member 13 is extended from the carrier module 12, it can pierce the air bag 400 on the clamping mechanism. It can also be seen that when the piercing member 13 is retracted into the carrier module 12, it will not pierce the air bag 400 on the clamping mechanism.

[0059] When the airbag 400 needs to be punctured, the puncturing element 13 is extended from the carrier module 12, and when the airbag 400 does not need to be punctured, the puncturing element 13 is retracted into the carrier module 12. In this way, the puncturing element 13 can be prevented from puncturing the airbag 400 when it is not necessary, thereby reducing unnecessary losses.

[0060] In some embodiments, the puncturing mechanism further includes a push structure. The push structure is disposed on the carrier module 12 and connected to the puncturing member 13. The push structure is used to drive the puncturing member 13 to move so that the puncturing member 13 extends out of or retracts into the carrier module 12.

[0061] Specifically, the pushing structure is used to drive the piercing member 13 to move along the second direction, so that the piercing member 13 extends out of or retracts into the carrying module 12 .

[0062] Optionally, the pushing mechanism is a cylinder or other driving structure capable of driving the piercing member 13 to move.

[0063] In some embodiments, the carrier module 12 is provided with a receiving cavity 121 capable of receiving the piercing member 13. The piercing member 13 is configured to be controllably extended from or retracted into the receiving cavity 121.

[0064] It can be seen that when the airbag 400 needs to be punctured, the pushing structure drives the puncturing member 13 to extend from the accommodating cavity 121 ; when the airbag 400 does not need to be punctured, the pushing structure drives the puncturing member 13 to retract into the accommodating cavity 121 .

[0065] In some embodiments, the carrier module 12 includes a first carrier 122 and a second carrier 123 spaced apart from each other. The first carrier 122 and the second carrier 123 are configured to controllably move closer to or farther from each other, and the piercing element 13 is disposed on the first carrier 122. As the first carrier 122 and the second carrier 123 move closer to each other, the first carrier 122 and the second carrier 123 can clamp the airbag 400, and the piercing element 13 on the first carrier 122 can pierce the airbag 400.

[0066] It is understood that the accommodating cavity 121 is defined within the first carrier 122, specifically, the accommodating cavity 121 being defined on a surface of the first carrier 122 that faces the second carrier 123. The piercing member 13 extending out of the accommodating cavity 121 means that the tip of the piercing member 13, which is used to pierce the airbag 400, moves toward the second carrier 123 and is able to extend between the first carrier 122 and the second carrier 123.

[0067] Furthermore, the first supporting member 122 and the second supporting member 123 are spaced apart along the second direction, and the first supporting member 122 is movably disposed on the mounting base 14 along the second direction, while the second supporting member 123 is fixed to the mounting base 14. The first supporting member 122 can move closer to or farther from the second supporting member 123 during the reciprocating movement along the second direction.

[0068] Of course, in other embodiments, the second carrier 123 may move along the second direction while the first carrier 122 is fixed, or both the first carrier 122 and the second carrier 123 may move along the second direction. This is not limited here.

[0069] In some embodiments, the first carrier 122 and the second carrier 123 each include a mounting beam 124 and a supporting portion 125. The mounting beam 124 is connected to the mounting seat 14, the supporting portion 125 is fixedly connected to the mounting beam 124, and the piercing member 13 is disposed on the supporting portion 125.

[0070] In some embodiments, the carrier module 12 further includes a pressure rod 126 and an elastic member 127. The pressure rod 126 is movably connected to the first carrier 122. When the first carrier 122 and the second carrier 123 approach each other, the pressure rod 126 can press against the second carrier 123. That is, the pressure rod 126 is located on the side of the first carrier 122 facing the second carrier 123. The elastic member 127 is connected between the first carrier 122 and the pressure rod 126 to provide a force for the pressure rod 126 to press against the second carrier 123.

[0071] It is understood that the compression rod 126 can press against the second carrier 123. Therefore, when the air bag 400 is located between the first carrier 122 and the second carrier 123, the compression rod 126 can press the air bag 400 against the second carrier 123. At the same time, the elastic member 127 provides the compression force of the compression rod 126, thereby preventing the compression rod 126 from crushing the air bag 400.

[0072] In addition, the piercing member 13 can extend out of the pressure rod 126 under the driving of the pushing structure to pierce the air bag 400 pressed by the pressure rod 126.

[0073] Furthermore, the compression rod 126 is connected to the bearing portion 125 of the first bearing member 122 , and the elastic member 127 is connected between the bearing portion 125 of the first bearing member 122 and the compression rod 126 .

[0074] Optionally, the elastic member 127 is a spring.

[0075] In some embodiments, the puncture mechanism further includes a first adsorption member 15 and a second adsorption member 16. The first adsorption member 15 and the second adsorption member 16 are spaced apart from each other on the carrier module 12 and are configured to respectively adsorb two sides of the air bag 400. The first adsorption member 15 and the second adsorption member 16 can be controlled to move closer to or farther from each other, thereby adsorbing two sides of the air bag 400 as they approach, and then moving away from each other to open the air bag 400.

[0076] Compared with the prior art in which the first adsorption member 15 and the second adsorption member 16 are arranged in the packaging mechanism, the use of this puncture mechanism can make the position where the air bag 400 is adsorbed by the first adsorption member 15 and the second adsorption member 16 away from the sealing position, thereby making the seal tighter.

[0077] Furthermore, the first adsorption member 15 and the second adsorption member 16 are respectively disposed on the first supporting member 122 and the second supporting member 123 , so as to move closer to or farther away from each other as the first supporting member 122 and the second supporting member 123 move closer to or farther away from each other.

[0078] Of course, in other embodiments, the first adsorption member 15 and the second adsorption member 16 may also be driven by independent driving structures to move closer to or farther away from each other.

[0079] Furthermore, both the first adsorption member 15 and the second adsorption member 16 are disposed on the support portion 125, with the adsorption end of the first adsorption member 15 passing through the pressure rod 126 and located on the side of the pressure rod 126 facing the second support portion 123, while the adsorption end of the second adsorption member 16 passes through the support portion 125 of the second support portion 123 and located on the side of the second support portion 122. Thus, when the pressure rod 126 presses the air bag 400 against the support portion 125 of the second support portion 123, the first adsorption member 15 and the second adsorption member 16 can respectively adsorb both sides of the air bag 400. Then, the first support portion 122 and the second support portion 123 move away from each other, and the first adsorption member 15 and the second adsorption member 16 move accordingly, opening the air bag 400 to facilitate degassing.

[0080] It is certain that when there are multiple groups of carrier modules 12, the number of first adsorption members 15 and second adsorption members 16 is also multiple, and each carrier module 12 is provided with a first adsorption member 15 and a second adsorption member 16. In addition, to ensure the adsorption effect, at least two first adsorption members 15 and second adsorption members 16 can be provided on the first carrier 122 and second carrier 123 of each group of carrier modules 12, respectively.

[0081] In conjunction with the above embodiment, it should be noted that after the clamping mechanism clamps the airbag 400 , the position of the mounting seat 14 is adjusted according to the height of the airbag 400 until the piercing member 13 moves to a position capable of piercing the airbag 400 .

[0082] Next, the first carrier 122 and the second carrier 123 move closer to each other until the pressure rod 126 presses the air bag 400 against the second carrier 123. Then, the pushing mechanism drives the piercing member 13 to extend and pierce the air bag 400. At the same time, the first adsorption member 15 and the second adsorption member 16 respectively adsorb both sides of the air bag 400.

[0083] Next, the first carrier 122 and the second carrier 123 move away from each other, and the first adsorption member 15 and the second adsorption member 16 move away from each other and open the air bag 400, thereby facilitating the extraction of gas in the air bag 400.

[0084] In some embodiments, the lower chamber 200 further includes a bottom frame 210, and the middle chamber 300 further includes an intermediate frame 310. The bottom frame 210, the intermediate frame 310, and the mounting plate 110 are sequentially connected to enclose a packaging machine having a vacuum chamber. Components such as the mounting base 14 and the carrier module 12 are located within the vacuum chamber.

[0085] 5 and 6 , in some embodiments, the clamping mechanism includes a plurality of clamps 20 and a plurality of first driving modules 30. The plurality of first driving modules 30 are connected to the outside of the bottom frame 210. The driving end of each first driving module 30 extends into the vacuum chamber and is in driving connection with a corresponding clamp 20 to drive the clamp 20 to clamp or release the air bag 400.

[0086] It can be confirmed that the piercing member 13 is used to pierce the air bag 400 clamped by the clamp 20. The carrying module 12 can drive the piercing member 13 to approach or move away from the clamp 20.

[0087] Referring to Figure 11 , in some embodiments, the encapsulation mechanism includes a plurality of encapsulation modules 40 and a plurality of second drive modules 50. The plurality of second drive modules 50 are connected to the outside of the middle frame, and the driving end of each second drive module 50 extends into the vacuum chamber and is in transmission connection with a corresponding encapsulation module 40, thereby driving the encapsulation module 40 to encapsulate the corresponding air bag 400 on the fixture 20.

[0088] Using the above-mentioned packaging machine, each clamp 20 clamps an air bag 400, and then the air bag 40 is packaged through the corresponding packaging module 40. The actions of the clamp 20 and the packaging module 40 are driven by the first driving module 30 and the second driving module 50 respectively. The first driving module 30 and the second driving module 50 will not occupy the space in the vacuum chamber, so that more clamps 20 and packaging modules 40 can be placed in the vacuum chamber, thereby realizing the packaging of more air bags 400 at the same time, thereby improving processing efficiency.

[0089] 1 , the plurality of carrier modules 12 are located above the plurality of packaging modules 40 , which are located above the plurality of fixtures 20 , and the plurality of carrier modules 12 , the plurality of packaging modules 40 and the plurality of fixtures 20 correspond one to one in the vertical direction.

[0090] Furthermore, the plurality of fixtures 20 are arranged at intervals along the second direction, and the corresponding plurality of packaging modules 40 are arranged at intervals along the second direction.

[0091] The second direction is the left-right direction in FIG. 5 and FIG. 6 .

[0092] Optionally, the number of the fixture 20, the packaging module 40, the first driving module 30, and the second driving module 50 are all four. Two of the first driving modules 30 are connected to one side of the bottom frame 210 along the second direction, and the other two of the first driving modules 30 are connected to the other side of the bottom module. Two of the second driving modules 50 are connected to one side of the middle frame 310 along the second direction, and the other two of the second driving modules 50 are connected to the other side of the middle frame 310.

[0093] 5 , 6 , and 8 , in some embodiments, each clamp 20 includes a first clamping assembly 21 and a second clamping assembly 22. The first clamping assembly 21 and the second clamping assembly 22 are sequentially arranged in the vacuum chamber along the second direction and can move closer to or farther from each other to clamp the air bag 400 during the process of moving closer to each other. The first driving module 30 is in transmission connection with the first clamping assembly 21 and / or the second clamping assembly 22 to drive the first clamping assembly 21 and the second clamping assembly 22 to move closer to or farther from each other.

[0094] It can be understood that in this embodiment, the first clamping component 21 and the second clamping component 22 are close to or far away from each other, and both the first clamping component 21 and the second clamping component 22 can move back and forth along the second direction, or one of the first clamping component 21 and the second clamping component 22 can move back and forth along the second direction.

[0095] Of course, preferably, the first clamping assembly 21 and the second clamping assembly 22 are both reciprocatable along the second direction. The subsequent embodiments are described based on this preferred embodiment, but it does not affect the application of the structure in the subsequent embodiments to the embodiment in which one of the first clamping assembly 21 and the second clamping assembly 22 is reciprocatable along the second direction.

[0096] Optionally, the first clamping assembly 21 and the second clamping assembly 22 are both disposed on the bottom frame 210 so as to be reciprocally movable along the second direction.

[0097] 6 to 8 , in some embodiments, each clamp 20 further includes a guide rod 23. The guide rod 23 is longitudinally arranged in the vacuum chamber along the second direction, and the first clamping assembly 21 and the second clamping assembly 22 are slidably connected to the guide rod 23 so that the guide rod 23 guides the movement of the first clamping assembly 21 and the second clamping assembly 22.

[0098] Furthermore, each clamp 20 includes a plurality of guide rods 23. The plurality of guide rods 23 are divided into two groups, with the two groups of guide rods 23 arranged at intervals along a third direction perpendicular to the second direction. The first clamping assembly 21 and the second clamping assembly 22 are arranged longitudinally along the third direction, and the first clamping assembly 21 and the second clamping assembly 22 are slidably connected to the two groups of guide rods 23 at their respective ends along the third direction.

[0099] The third direction is the direction perpendicular to the paper in FIG5 , and is the up-down direction in FIG6 .

[0100] Optionally, each group of guide rods 23 includes two guide rods.

[0101] In some embodiments, each clamp 20 further includes a limiting member 24 , which is disposed on the guide rod 23 and is used to limit the movement of the first clamping assembly 21 and the second clamping assembly 22 .

[0102] Optionally, both ends of each guide rod 23 are connected to the limiting members 24 , and the first clamping assembly 21 and the second clamping assembly 22 may abut against the limiting members 24 during movement, thereby limiting the movement of the first clamping assembly 21 and the second clamping assembly 22 .

[0103] In some embodiments, each clamp 20 also includes a linkage 25, which is connected between the first clamping component 21 and the second clamping component 22, so that the first clamping component 21 and the second clamping component 22 can move closer to or away from each other synchronously, ensuring the accuracy of the first clamping component 21 and the second clamping component 22 in clamping the air bag 400.

[0104] It can be understood that by realizing the linkage of the first clamping assembly 21 and the second clamping assembly 22 through the linkage member 25, the number of limit members 24 used can be reduced, that is, setting a limit member 24 at one end of the guide rod 23 can also achieve simultaneous restriction of the movement of the first clamping assembly 21 and the second clamping assembly 22.

[0105] Optionally, the linkage member 25 is a scissors-type fork.

[0106] Please refer to Figures 8 to 9. In some embodiments, the first clamping assembly 21 includes a first support plate 211 and a first pressure plate 212. The first support plate 211 is arranged in the vacuum chamber so as to be reciprocatingly movable along the second direction. The first pressure plate 212 is connected to the side of the first support plate 211 close to the second clamping assembly 22, and is used to clamp the air bag 400 with the second clamping assembly 22.

[0107] Furthermore, the first clamping assembly 21 also includes a first fixing block 213. The first support plate 211 is arranged longitudinally along the third direction. The first fixing block 213 is connected to the other side of the first support plate 211 away from the second clamping assembly 22, and the first fixing block 213 is located in the middle of the first support plate 211 along the third direction. The driving end of the first driving module 30 is in driving connection with the first fixing block 213. In this way, the driving force of the driving end is applied to the middle of the first support plate 211, preventing the first support plate 211 from deflecting during movement.

[0108] In some embodiments, the first clamping assembly 21 also includes a first clamping plate 214, which is connected to the first support plate 211, and the height of the first clamping plate 214 is higher than the first pressure plate 212. The first pressure plate 212 cooperates with the second clamping assembly 22 to clamp and fix the air bag 400, and the first clamping plate 214 is used to support the top of the air bag 400.

[0109] In some embodiments, the second clamping assembly 22 includes a second support plate 221 and a second pressure plate 222. The second support plate 221 is arranged in the vacuum chamber so as to be reciprocatingly movable along the second direction. The second pressure plate 222 is connected to the side of the second support plate 221 close to the second clamping assembly 22, and is used to clamp the air bag 400 with the second clamping assembly 22.

[0110] Furthermore, the second clamping assembly 22 also includes a second fixed block 223, the second support plate 221 is arranged longitudinally along the third direction, the second fixed block 223 is connected to the other side of the second support plate 221 away from the second clamping assembly 22, and the second fixed block 223 is located in the middle position of the second support plate 221 along the third direction, and the driving end of the first driving module 30 is transmission connected to the second fixed block 223.

[0111] In some embodiments, the second clamping assembly 22 also includes a second clamping plate 224, which is connected to the second support plate 221, and the height of the second clamping plate 224 is higher than the second pressure plate 222. The second pressure plate 222 cooperates with the first pressure plate 212 to clamp and fix the air bag 400, and the first clamping plate 214 and the second clamping plate 224 are used to support the top of the air bag 400.

[0112] Please refer to Figures 6, 7 and 10. In some embodiments, each first driving module 30 includes a mounting frame 31, a first clamping driving component 32 and a second clamping driving component 33. The mounting frame 31 is connected to the outside of the bottom frame 210. The first clamping driving component 32 and the second clamping driving component 33 are both arranged on the mounting frame 31, and the driving end of the first clamping driving component 32 extends into the vacuum chamber and is transmission-connected to the first clamping component 21. The driving end of the second clamping driving component 33 extends into the vacuum chamber and is transmission-connected to the second clamping component 22, so as to respectively drive the first clamping component 21 and the second clamping component 22 to move back and forth along the second direction, thereby realizing that the first clamping component 21 and the second clamping component 22 are close to or away from each other.

[0113] Optionally, the mounting bracket 31 is connected to the bottom frame 210 .

[0114] In some embodiments, the first clamping drive assembly 32 includes a first clamping drive member 321, a first transmission rod 322 and a first connecting block 323. The first clamping drive member 321 is arranged on the mounting frame 31 and is transmission-connected to the first transmission rod 322 to drive the first transmission rod 322 to move back and forth along the second direction. The first transmission rod 322 is arranged longitudinally along the second direction, and one end extends into the vacuum chamber. The first connecting block 323 is connected between the end of the first transmission rod 322 extending into the vacuum chamber and the first clamping assembly 21.

[0115] Furthermore, the first connecting block 323 is connected to the bottom frame 210 so as to be reciprocatingly movable along the second direction, and the first connecting block 323 is connected to the first fixed block 213 to transmit the driving force to the middle position of the first support plate 211 through the first connecting block 323 and the first fixed block 213.

[0116] Optionally, the first clamping drive assembly 32 further includes a first connecting shaft 324 . The first connecting block 323 is located below the first fixing block 213 . The first connecting shaft 324 is connected between the first connecting block 323 and the first fixing block 213 .

[0117] In some embodiments, the second clamping drive assembly 33 includes a second clamping drive member 331, a second transmission rod 332 and a second connecting block 333. The second clamping drive member 331 is arranged on the mounting frame 31 and is transmission-connected to the second transmission rod 332 to drive the second transmission rod 332 to move back and forth along the second direction. The second transmission rod 332 is arranged longitudinally along the second direction, and one end extends into the vacuum chamber. The second connecting block 333 is connected between the end of the second transmission rod 332 extending into the vacuum chamber and the second clamping assembly 22.

[0118] Similarly, it can be known that the second connecting block 333 is connected to the bottom frame 210 so as to be reciprocatable along the second direction, and the second connecting block 333 is connected to the second fixing block 223 via a second connecting shaft.

[0119] It is understood that the first clamping assembly 21 and the second clamping assembly 22 are arranged sequentially along the second direction, so the first transmission rod 322 and the second transmission rod 332 have different lengths. Specifically, the first transmission rod 322 is shorter than the second transmission rod 332. At the same time, to ensure transmission stability, the number of the longer second transmission rods 332 is two.

[0120] In addition, regarding the first driving module 30 driving the middle clamp 20, as shown in FIG6 , the first transmission rod 322 and the second transmission rod 332 in the two first driving modules 30 driving the two middle clamps 20 are both longer, and pass under the two side clamps 20, and then are respectively connected to the first connecting block 323 and the second connecting block 333.

[0121] It should be noted that, in order to ensure the sealing of the vacuum chamber, when the first transmission rod 322 and the second transmission rod 332 pass through the bottom frame 210 , a sealing structure is provided between the first transmission rod 322 and the second transmission rod 332 and the bottom frame 210 .

[0122] In some embodiments, the second clamping drive assembly 33 also includes a drive block 334 and a limit block 335. The drive block 334 is connected between the second clamping drive member 331 and the second transmission rod 332. The limit block 335 is connected to the mounting frame 31 and is used to limit the moving range of the drive block 334, thereby limiting the moving range of the second clamping assembly 22 to avoid crushing the airbag 400.

[0123] It is clear that due to the linkage of the linkage member 25, the limit block 335 limits the movement range of the second clamping assembly 22, which can also indirectly limit the movement range of the first clamping assembly 21. Of course, in other embodiments, additional limit structures can be provided to limit the movement range of the first transmission rod 322, thereby limiting the movement range of the first clamping assembly 21, further preventing the first and second pressure plates 212, 222 from crushing the airbag 400.

[0124] Furthermore, the second clamping drive assembly 33 further includes a buffer 336 , which is connected to the limiting block 335 . The buffer 336 is used to abut against the driving block 334 , so that the limiting effect of the limiting block 335 on the driving block 334 is buffered.

[0125] Please refer to Figures 11 and 12. In some embodiments, each packaging module 40 includes a first head 41 and a second head 42. The first head 41 and the second head 42 are arranged in sequence in the vacuum chamber along the second direction, and the first head 41 can move back and forth along the second direction. The second driving module 50 is transmission-connected to the first head 41 to drive the first head 41 to approach or move away from the second head 42, and the air bag 400 can be packaged in the process of the first head 41 approaching the second head 42.

[0126] It can be understood that the first head 41 and the second head 42 have the same structure, but the difference is that the first head 41 is connected to the middle frame 310 so as to be reciprocatingly movable along the second direction, while the second head 42 is fixed to the middle frame 310.

[0127] In addition, it should be noted that explosion-proof measures are taken for the heating wires or heating rods in the first and second end caps 41 and 42. For example, the end caps are made of explosion-proof materials with good thermal conductivity.

[0128] In some embodiments, the second driving module 50 includes a packaging driving member 51 and a connecting rod 52. The packaging driving member 51 is connected to the outside of the middle frame 310 and is transmission-connected to the connecting rod 52 to drive the connecting rod 52 to move back and forth along the second direction. The connecting rod 52 extends along the second direction, and one end of the connecting rod 52 extends into the vacuum chamber and is transmission-connected to the first head 41.

[0129] It is understandable that a sealing structure is also provided between the connecting rod 52 and the middle frame 310 .

[0130] Optionally, each package driving member 51 includes two package driving members 51 and two connecting rods 52 to improve driving stability.

[0131] It should be noted that, as shown in Figure 11, since the four packaging modules 40 are arranged in a spaced arrangement along the second direction, the second driving module 50 that drives the two middle packaging modules 40 has a longer connecting rod 52. At the same time, to facilitate installation, connecting plates 53 can be added to the two packaging modules 40 to allow the two longer connecting rods 52 to be arranged in a spaced arrangement along the third direction. These connecting rods 52 can then be connected to the corresponding first end caps 41 via connecting bases 54.
