[0055] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0056] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The following embodiments and features in the embodiments can be combined with each other unless there is a conflict.

[0057] In the prior art, the nailing operation is performed using a nailing device. The nailing device includes a frame, a positioning mechanism, a nailing mechanism, a negative pressure generating mechanism, and related cooperating mechanisms. The positioning mechanism, nailing mechanism, and negative pressure generating mechanism are all mounted on the frame. The positioning mechanism is used to position and clamp the battery to be nailed, the negative pressure generating mechanism is used to create a negative pressure environment around the battery to degas the battery, and the nailing mechanism is used to insert the sealing nail into the liquid filling port.

[0058] However, existing nailing equipment cannot completely discharge the gas in the battery through a negative pressure environment, which easily causes residual gas to remain in the battery. After the battery is nailed, the battery is prone to expansion due to the internal residual gas, causing the battery thickness to exceed the standard, affecting the battery's cycle life and battery performance.

[0059] Furthermore, existing nailing equipment is usually only used for nailing batteries of a certain specification, has low compatibility with battery specifications, and has poor positioning stability.

[0060] In order to overcome the defects in the prior art, the embodiments of the present application provide a battery nailing auxiliary structure and nailing equipment. The battery nailing auxiliary structure is provided by arranging a positioning mechanism and a venting mechanism on the support frame. The positioning mechanism can clamp the battery to be nailed so that the relative position of the battery is stable, and the positioning mechanism can form a restrained area on the side of the battery. The venting mechanism can abut against the restrained area and heat the restrained area so that the residual air in the battery expands due to the heat and is then discharged, and / or the restrained area can be pressurized to squeeze out the residual air in the battery. In this way, the gas discharge rate in the battery under negative pressure environment can be higher, avoiding the expansion of gas after the battery is nailed, which affects the battery life and battery performance.

[0061] The content of the present invention will be described in detail below with reference to the accompanying drawings so that those skilled in the art can understand the content of the present invention more clearly and in detail.

[0062] Reference Figures 1 to 3 As shown, in some embodiments, the present application provides a battery nail auxiliary structure, including:

[0063] Support frame;

[0064] The positioning mechanism 100 is provided on the support frame. The positioning mechanism 100 is used to position and clamp the battery 400 to be inserted with a nail, and to form a restrained area 410 on the side of the battery 400;

[0065] The exhaust facilitating mechanism 200 is provided on the support frame. The exhaust facilitating mechanism 200 is used to abut against the restrained area 410 and apply pressure and / or heat to the restrained area 410 .

[0066] Figures 1 to 5 In the three-dimensional space, the X, Y, and Z directions are perpendicular to each other.

[0067] It can be understood that the battery nailing auxiliary structure is applied to the nailing device. Specifically, it can be placed in a negative pressure environment formed by the negative pressure generating mechanism of the nailing device to improve the gas discharge rate in the battery 400 under the negative pressure environment.

[0068] During specific implementation, the support frame can be fixedly connected to the frame of the nail plugging device, so that the support frame can provide installation support for the positioning mechanism 100 and the exhaust mechanism 200 to ensure the stability of the installation of the positioning mechanism 100 and the exhaust mechanism 200.

[0069] The positioning mechanism 100 can position and clamp the battery 400 that needs to be nailed, thereby ensuring that the battery 400 can be stably maintained in a fixed position in a negative pressure environment during the nailing process, without positional displacement due to vibration of the mechanism operation or the force of the nailing.

[0070] Furthermore, by clamping the battery 400 with the positioning mechanism 100, a restrained area 410 can be formed on the side of the battery 400 while the battery 400 is fixed. For example, the restrained area 410 can be located on one of the six surfaces of the battery 400 with a relatively large area, thereby increasing the area of the restrained area 410 and facilitating contact and cooperation with the exhaust promotion mechanism 200.

[0071] The exhaust facilitating mechanism 200 is disposed on one side of the positioning mechanism 100 and can contact the restrained area 410 on the side of the battery 400, thereby applying pressure, heating, or both pressure and heating to the restrained area 410. It can be understood that applying pressure to the side of the battery 400 housing can cause the housing to deform under compression, reducing its internal volume and thereby facilitating the exhaust of gases within the housing. Conversely, heating the side of the battery 400 housing can cause the gas within the housing to expand due to the heat, also facilitating the exhaust of gases within the housing.

[0072] Therefore, the battery nailing auxiliary structure provided in the embodiment of the present application is provided with a positioning mechanism 100 and a gas exhaust mechanism 200 on the support frame. The positioning mechanism 100 can clamp the battery 400 to be nailed so that the relative position of the battery 400 is stable, and the positioning mechanism 100 can form a restrained area 410 on the side of the battery 400. The gas exhaust mechanism 200 can abut against the restrained area 410 and heat the restrained area 410 so that the residual air in the battery 400 expands due to the heat and is discharged, and / or, the restrained area 410 can be pressurized to squeeze out the residual air in the battery 400. In this way, the gas exhaust rate in the battery 400 can be higher under a negative pressure environment, thereby preventing the gas from expanding after the battery 400 is nailed, which affects the service life and performance of the battery 400.

[0073] In some embodiments, reference Figures 1 to 3 As shown, the exhaust promoting mechanism 200 includes:

[0074] A first mounting base 210, the first mounting base 210 is connected to the support frame;

[0075] The restraining member 220 is movably disposed on the first mounting seat 210 . The restraining member 220 is used to make or break surface contact with the restrained area 410 along its own moving direction.

[0076] One side of the first mounting base 210 along the X direction can be fixedly connected to the support frame by bolts, rivets or welding, and a restraint 220 is provided on the other side of the first mounting base 210 along the X direction. The restraint 220 is arranged opposite to the restrained area 410 of the battery 400. The restraint 220 can move relative to the first mounting base 210 along the Y direction, and then approach the restrained area 410 to make surface contact with the restrained area 410, or move away from the restrained area 410 to break away from surface contact with the restrained area 410.

[0077] The restraining member 220 includes a connecting portion and a contact portion. The connecting portion extends along the Y direction and is connected to the first mounting base 210, thereby being movable relative to the first mounting base 210 along the Y direction. The contact portion is provided at one end of the connecting portion away from the first mounting base 210 along the Y direction and can be configured as at least two plate-like structures spaced apart along the Y direction, or an inflatable airbag structure, to facilitate surface contact between the restraining member 220 and the restrained area 410.

[0078] The restraining member 220 is arranged to be in surface contact with the restrained area 410, thereby increasing the contact area between the restraining member 220 and the restrained area 410. Thus, when the restraining member 220 applies pressure to the restrained area 410, the pressure exerted by the restraining member 220 on the restrained area 410 can be reduced, thereby preventing the restrained area 410 from being punctured by the restraining member 220 and causing damage to the battery 400. Furthermore, when the restraining member 220 heats the restrained area 410, the heat conduction efficiency between the restraining member 220 and the restrained area 410 can be improved, thereby ensuring effective exhaust within the battery 400.

[0079] Among them, reference Figures 1 to 3 As shown, the exhaust promoting mechanism 200 further includes a pressurizing member 230 , which is disposed on the first mounting seat 210 and connected to the restraining member 220 ;

[0080] The pressurizing member 230 is configured to drive the restraining member 220 to move, and after the restraining member 220 comes into surface contact with the restrained area 410 , drive the restraining member 220 to pressurize the restrained area 410 .

[0081] Among them, the restraint 220 is arranged on one side of the first mounting seat 210 along the Y direction facing the battery 400 and the positioning mechanism 100, and the pressure member 230 is arranged on the other side of the first mounting seat 210 along the Y direction and connected to the restraint 220 to make the structure of the exhaust mechanism 200 more compact and stable.

[0082] The pressure member 230 is in transmission connection with the connecting portion of the restraining member 220 , and can drive the connecting portion to move relative to the first mounting seat 210 along the Y direction, and the connecting portion drives the contact portion to move.

[0083] When the pressure-applying member 230 drives the restraining member 220 to move along the Y direction until it contacts the restrained area 410, it can continuously output driving force to the restraining member 220 to apply pressure to the restrained area 410 through the restraining member 220, thereby squeezing the shell of the battery 400, causing the shell of the battery 400 to deform to a certain extent within a safety limit, thereby expelling the internal gas.

[0084] In a specific implementation, the pressure member 230 can be a drive structure capable of outputting linear motion along the Y direction, such as a linear motion motor or a piston cylinder, etc., which is not limited in this application. Utilizing the pressure member 230 to drive the movement of the restraining member 220 and apply pressure to the restrained area 410 eliminates the need for a movable drive component for the restraining member 220, reduces the number of components, and makes the restraint auxiliary structure simpler and more compact.

[0085] Further, refer to Figures 1 to 3 As shown, the exhaust promoting mechanism 200 further includes a pressure detecting member 240, which is disposed on the restraining member 220 and is in communication with the pressurizing member 230. The pressure detecting member 240 is used to detect the pressure value applied by the pressurizing member 230 on the restrained area 410;

[0086] The pressurizing member 230 is further configured to stop driving when the pressure value is greater than or equal to a preset pressure value.

[0087] By providing the pressure detection member 240 , the driving force output by the pressure member 230 can be controlled within a reasonable range, preventing the pressure member 230 from excessively pressurizing the restrained area 410 through the restraining member 220 , thereby preventing the battery 400 from being ruptured and damaged due to excessive pressure.

[0088] For example, the pressure detection member 240 can be a pressure sensor, which is disposed between two adjacent plate structures on the contact portion of the restraining member 220 and abuts against each of the two plate structures. Based on the interaction force, it converts the pressure between the restraining member 220 and the restrained area 410 into the pressure between the two adjacent plate structures at the contact portion. This allows accurate detection of the pressure applied to the restrained area 410 while preventing the pressure detection member 240 from affecting the stability of the surface contact.

[0089] Among them, the preset pressure value can be determined according to the pressure limit corresponding to the model specification of the nail battery 400 to be inserted. Specifically, the preset pressure value range can be set to be greater than or equal to 0.1MPa and less than or equal to 0.3MPa. This application does not impose any restrictions on this.

[0090] Further, refer to Figures 1 to 3 As shown, the exhaust promoting mechanism 200 further includes a heating element 250 , which is connected to the restraining element 220 to heat the restrained area 410 through the restraining element 220 .

[0091] By arranging the heating element 250 on the restraining element 220 , when the temperature of the heating element 250 rises, the heat can be transferred to the restrained area 410 through the restraining element 220 , so as to achieve the expansion of the gas in the restrained area 410 due to the heat.

[0092] Among them, reference Figures 1 to 3 As shown, the heating element 250 includes a plurality of electric heating tubes 251 sequentially arranged in intervals within the restraining element 220 .

[0093] It can be understood that multiple electric heating tubes 251 are sequentially arranged along the Z direction in the restraining member 220. The structure is relatively simple, which can make the heat distribution of the restraining member 220 more uniform and the heating rate faster.

[0094] And, refer to Figure 2 As shown, the exhaust promoting mechanism 200 further includes a temperature detecting member 260 , which is disposed on the restraining member 220 and is in communication with the heating member 250 . The temperature detecting member 260 is used to detect the temperature value of the restraining member 220 .

[0095] The heating element 250 is configured to stop heating when the temperature value is greater than or equal to a preset temperature value.

[0096] By providing the temperature detection element 260 , the heating temperature of the heating element 250 can be controlled within a reasonable range, preventing the temperature of the heating element 250 from being too high and exceeding the limit of the battery 400 , causing the battery 400 to overheat and run away.

[0097] Exemplarily, the temperature detection element 260 can be a thermocouple, which is connected to at least one heating element 250 and can convert the temperature change of the heating element 250 into an electric potential change. It has the characteristics of fast response speed, wide measurement range, and high measurement accuracy, so as to measure the temperature of the heating element 250 more accurately and timely.

[0098] Among them, the preset temperature value can be determined according to the model and specifications of the battery 400 to be inserted. Specifically, the preset temperature value range can be set to be greater than or equal to 25°C and less than or equal to 150°C. This application does not impose any restrictions on this.

[0099] In some embodiments, reference Figure 2 As shown, the exhaust promoting mechanism 200 further includes a first guide member 270 , which is disposed on the restraining member 220 and is slidably connected to the first mounting seat 210 . The sliding direction of the first guide member 270 is consistent with the moving direction of the restraining member 220 .

[0100] By setting the first guide member 270, the first guide member 270 extends along the Y direction, so that the extension direction of the first guide member 270 is consistent with the movement direction of the restraint member 220, so that when the restraint member 220 moves along the Y direction relative to the first mounting seat 210, the first guide member 270 provides support and guidance, so that the movement of the restraint member 220 is more stable and smooth.

[0101] A sliding bearing 271 is provided on the first mounting seat 210 , and the guide member is slidably inserted into the sliding bearing 271 , so that the sliding is smoother.

[0102] And, refer to Figures 1 to 3 As shown, in a specific implementation, the restraining member 220 has a restraining plane 221 , and the area of the restraining plane 221 is smaller than or equal to the area of the restrained region 410 .

[0103] The area of the restraining plane 221 is set to be smaller than the area of the restrained area 410 to ensure that the restraining member 220 can be in stable surface contact with the restrained area 410 without interfering with the positioning mechanism 100.

[0104] Exemplarily, the contact portion of the restraint 220 can be a rigid structure having a plate, and its restraint plane 221 can be a corresponding plane of the plate structure facing the restrained area 410. The contact portion can also be an airbag structure. After the airbag structure is inflated, a flat part is formed on one side facing the restrained area 410. This application does not impose any restrictions on this.

[0105] In some embodiments, reference Figure 1 、 Figure 3 and Figure 4 As shown, the positioning mechanism 100 includes:

[0106] A second mounting base 110, the second mounting base 110 is connected to the support frame;

[0107] A first positioning assembly 120 is disposed on the second mounting base 110 and is used to position and support the battery 400 so that a side surface of the battery 400 faces the exhaust facilitating mechanism 200;

[0108] The second positioning component 130 is arranged on the second mounting seat 110, and the second positioning component 130 is located on one side of the first positioning component 120. The second positioning component 130 is used to abut against the side of the battery 400 to clamp the battery 400 in the first positioning component 120, and form a restrained area 410 on the other side of the battery 400 away from the first positioning component 120.

[0109] The second mounting seat 110 is disposed on the support frame and is located on the same side of the support frame as the first mounting seat 210 , so as to facilitate the cooperation between the positioning mechanism 100 and the exhaust promoting mechanism 200 .

[0110] The first positioning assembly 120 and the second positioning assembly 130 are both arranged on the second mounting base 110. The first positioning assembly 120 can support the side of the battery 400 along the Y direction away from the exhaust mechanism 200 and the bottom of the battery 400 along the Z direction, while the second positioning assembly 130 abuts against the side of the battery 400 along the Y direction toward the exhaust mechanism 200 to clamp the battery 400 between the first positioning assembly 120 and the second positioning assembly 130 to ensure the stability of the positioning and clamping of the battery 400.

[0111] During specific use, the first positioning component 120 and the second positioning component 130 can be flexibly adjusted according to the size specifications of the battery 400 to make the first positioning component 120 and the second positioning component 130 adapt to the size of the battery 400, thereby improving the compatibility of the positioning mechanism 100 and being suitable for batteries 400 of different sizes.

[0112] Among them, reference Figure 1 、 Figure 3 and Figure 4 As shown, the first positioning assembly 120 includes:

[0113] A first support plate 121 , which is disposed perpendicularly to the second mounting base 110 and faces the exhaust facilitating mechanism 200 . The first support plate 121 is configured to abut against a side of the battery 400 facing away from the exhaust facilitating mechanism 200 ;

[0114] The first adjusting member 122 is disposed on the first supporting plate 121 and moves vertically relative to the first supporting plate 121 to support the bottom of the battery 400 and make the top of the battery 400 correspond to the top of the first supporting plate 121 .

[0115] The second mounting base 110 is disposed along the YZ plane, and the first support plate 121 is disposed along the XZ plane, so that the first support plate 121 and the second mounting base 110 are perpendicular to each other and perpendicular to the moving direction of the exhaust promotion mechanism 200 .

[0116] At least two rows of adjustment holes are spaced apart along the Z direction on the first support plate 121. The first adjustment member 122 is a block-shaped structure that can be connected to different adjustment holes in the Z direction via bolts, allowing the height of the first adjustment member 122 to be adjusted along the Z direction. Specifically, the height of the first adjustment member 122 can be set based on the size of the battery 400 along the Z direction. When the bottom of the battery 400 abuts the first adjustment member 122, the top of the battery 400 should not be lower than the top of the first support plate 121 to prevent the first support plate 121 from interfering with subsequent nailing operations.

[0117] In some embodiments, reference Figure 1 、 Figure 3 and Figure 4 As shown, the second positioning assembly 130 includes:

[0118] A second support plate 131 , the second support plate 131 is disposed parallel to the second mounting base 110 ;

[0119] Two second adjusting members 132 , wherein one second adjusting member 132 is disposed on the second mounting base 110 or the second support plate 131 to clamp the upper portion of the side surface of the battery 400 , and the other second adjusting member 132 is disposed on the second support plate 131 and moves vertically relative to the second support plate 131 to clamp the lower portion of the side surface of the battery 400 ;

[0120] The area of the side surface of the battery 400 between the two second adjustment members 132 forms a restrained area 410 .

[0121] The second support plate 131 is disposed along the YZ plane, which is consistent with the arrangement direction of the second mounting base 110 , so that the second support plate 131 can be parallel to the second mounting base 110 .

[0122] Two second support plates 131 can be arranged at intervals along the Y direction, and at least two rows of adjustment holes are arranged at intervals along the Z direction on the two second support plates 131. The difference is that the intervals of the adjustment holes on the two support plates along the Z direction are different, so that the height of the second adjustment member 132 can be set more flexibly and accurately according to the height of the battery 400.

[0123] The two second adjustment members 132 correspond to the upper and lower portions of the side surface of the battery 400 along the Y direction, respectively, thereby ensuring a more stable and reliable clamping effect on the battery 400. Furthermore, the area between the two second adjustment members 132 on the side surface of the battery 400 forms a restrained area 410, so that the restraining member 220 can make surface contact with the restrained area 410.

[0124] Specifically, the second adjustment member 132 includes a rail seat 1321, a clamping slider 1322, and an adjustment rod 1323. The rail seat 1321 is detachably mounted on the second support plate 131 or the second mounting base 110 via bolts. The clamping slider 1322 is slidably mounted on the rail of the rail seat 1321 along the Y direction. The adjustment rod 1323 is rotatably mounted on the rail seat 1321 and is slidably connected to the clamping slider 1322 along the Y direction. Thus, when the adjustment rod 1323 rotates, the clamping slider 1322 is driven to move relative to the rail seat 1321 along the Y direction, thereby causing the clamping slider 1322 to abut or disengage with the battery 400. This facilitates adjustment of the relative position of the clamping slider 1322 according to the size of the battery 400 along the Y direction.

[0125] Furthermore, in some embodiments, reference Figure 3 and Figure 4As shown, the positioning mechanism 100 further includes a third positioning assembly 140 , which is disposed on the second mounting seat 110 . The third positioning assembly 140 has a receiving hole 141 for clamping the sealing nail, and the receiving hole 141 is opposite to the liquid filling port 420 of the battery 400 .

[0126] It is understood that a third positioning assembly 140 is provided on the second mounting base 110. The third positioning assembly 140 is provided with a receiving hole 141 adapted for the sealing pin, and the receiving hole 141 is opposite the liquid injection port 420 of the battery 400. Therefore, when inserting the pin, the sealing pin can be placed in the receiving hole 141 of the third positioning assembly 140 so that the sealing pin is opposite the liquid injection port 420. When inserting the pin later, there is no need to reposition the sealing pin; the sealing pin can simply be driven into the liquid injection port 420, making the inserting operation more efficient and accurate.

[0127] In addition, an embodiment of the present application further provides a battery nailing device, comprising a device body and a battery nailing auxiliary structure according to any of the above embodiments arranged on the device body.

[0128] The battery plugging auxiliary structure has been described in detail in the above embodiments and will not be repeated here.

[0129] Further, refer to Figures 1 to 5 As shown, the device body includes a nailing mechanism 300 , which is connected to a battery nailing auxiliary structure. The nailing mechanism 300 is used to drive a sealing nail to be inserted into the liquid filling port 420 of the battery 400 .

[0130] As can be understood, by providing a nailing mechanism 300 to drive the sealing nail into the liquid injection port 420, the nailing operation can be highly automated, making nailing more convenient and quick. Furthermore, connecting the nailing mechanism 300 to the battery nailing auxiliary structure facilitates placement of the nailing mechanism 300 and the battery nailing auxiliary structure within the negative pressure environment of the nailing device, resulting in a more compact structure.

[0131] When implementing it, refer to Figure 1 、 Figure 4 and Figure 5 The nailing mechanism 300 includes:

[0132] A third mounting base 310, the third mounting base 310 is connected to the support frame;

[0133] An operating member 320, the operating member 320 is used to abut against the sealing pin;

[0134] A first driving member 330, the first driving member 330 is connected to the operating member 320 to drive the operating member 320 to rotate around its own axis;

[0135] The second driving member 340 is arranged on the third mounting seat 310 and is connected to the first driving member 330. The second driving member 340 drives the first driving member 330 and the operating member 320 to approach the liquid injection port 420 along the axis of the operating member 320, so as to insert the sealing pin into the liquid injection port 420 through the operating member 320.

[0136] The third mounting bracket 310 is connected to the support frame to ensure stable installation. A second driver 340 is fixedly mounted on the third mounting bracket 310. This driver 340 is used to generate linear motion in the Z direction and can be a piston cylinder or linear motion motor. The output end of the second driver 340 is connected to the first driver 330, so that when the second driver 340 is in operation, it can drive the first driver 330 to move in the Z direction.

[0137] The first driving member 330 is used to output rotational motion, and specifically can be a rotational motion motor. An operating member 320 is provided along the Z direction at the output end of the first driving member 330 . When the first driving member 330 is running, the operating member 320 can be driven to rotate around the Z direction.

[0138] The operating member 320 can be specifically a push rod that pushes the sealing pin into the liquid injection port 420. When inserting the pin, the operating member 320 can move in the Z direction driven by the second driving member 340 and rotate around the Z direction driven by the first driving member 330, that is, the operating member 320 can be rotated. Compared to simply linearly advancing or rotating the operating member 320, providing the operating member 320 with rotational feeding and driving the sealing pin into position ensures a tighter and more reliable seal between the sealing pin and the liquid injection port 420.

[0139] In some embodiments, reference Figure 5 As shown, the nail inserting mechanism 300 also includes a second guide member 350, which is arranged on the third mounting seat 310, and the first driving member 330 is slidingly connected to the second guide member 350, and the sliding direction of the first driving member 330 is consistent with the axial direction of the operating member 320.

[0140] Among them, the output end of the second driving member 340 is provided with a connecting plate 360, the first driving member 330 is provided on the connecting plate 360, and a second guide member 350 is provided on the third mounting seat 310 along the Z direction. The second guide member 350 can be a slide rail, and the connecting member is provided with a slide groove that is adapted to be slidably connected to the slide rail, so that when the first driving member 330 moves along the Z direction, the second guide member 350 can provide stable guidance.

[0141] The nailing process of the nailing device is as follows: the operator places the battery 400 on the first positioning component 120 of the positioning mechanism 100 and is clamped by the second positioning component 130, and places the sealing nail on the third positioning component 140 of the positioning mechanism 100; then, the start button of the nailing device is pressed, and the nailing device forms a negative pressure environment around the battery 400 through the configured negative pressure generating mechanism; further, the exhaust mechanism 200 is promoted to move to the restrained area 410 of the battery 400 to pressurize and heat the battery 400; thereafter, the nailing mechanism 300 drives the sealing nail to be inserted into the liquid filling port 420 to complete the nailing operation; finally, the operator removes the battery 400 after nailing, and repeats the above steps.

[0142] In a further embodiment, a loading mechanism and a unloading mechanism may also be provided to replace the operator in loading and unloading, thereby further improving the working efficiency of the nailing equipment.

[0143] In summary, the nailing device provided in the embodiment of the present application is provided with a battery 400 nailing auxiliary mechanism, and the battery nailing auxiliary structure is provided by providing a positioning mechanism 100 and a degassing mechanism 200 on a support frame. The positioning mechanism 100 can clamp the battery 400 to be nailed so that the relative position of the battery 400 is stable, and the positioning mechanism 100 can form a restrained area 410 on the side of the battery 400. The degassing mechanism 200 can abut against the restrained area 410 and heat the restrained area 410 so that the residual air in the battery 400 expands due to the heat and is discharged, and / or can pressurize the restrained area 410 to squeeze out the residual air in the battery 400. In this way, the gas discharge rate in the battery 400 can be higher in a negative pressure environment, thereby preventing the gas from expanding after the battery 400 is nailed, which affects the service life and performance of the battery 400.
