[0050] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 7 The nailing machine 100 according to the first embodiment of the present invention is described. The nailing machine 100 of the present application is described in detail by taking the installation of the sealing nail 200 as an example.

[0051] like Figure 1-Figure 3 As shown, the nailing machine 100 according to the first embodiment of the present invention includes a main body 1, a nailing rod 2 and a clamping claw assembly 3.

[0052] Specifically, the nail rod 2 is arranged on the main body 1, and the nail rod 2 can rotate relative to the main body 1 around the central axis of the nail rod 2. The width of the nail rod 2 in the first direction is smaller than the width of the nail rod 2 in the second direction. The first direction and the second direction intersect and are both perpendicular to the central axis of the nail rod 2. Figure 1-Figure 3In the example, the nail rod 2 extends in the up-down direction, the upper end of the nail rod 2 is connected to the main body 1, the width of the nail rod 2 in the first direction is the short diameter of the nail rod 2, the width of the nail rod 2 in the second direction is the long diameter of the nail rod 2, and the plane where the first direction and the second direction are located is perpendicular to the central axis of the nail rod 2. Therefore, the nail rod 2 has a simple structure and is easy to produce, thereby improving the production rate of the nail rod 2.

[0053] Combination Figure 4 and Figure 5 As shown, the clamping jaw assembly 3 is arranged on the main body 1, and the clamping jaw assembly 3 includes a first clamping jaw portion 31 and a second clamping jaw portion 32. The nail rod 2 is arranged between the first clamping jaw portion 31 and the second clamping jaw portion 32. The clamping jaw assembly 3 is configured to clamp the nail rod 2 with the first clamping jaw portion 31 and the second clamping jaw portion 32 when the two sides of the nail rod 2 along the first direction cooperate with the clamping jaw assembly 3, and release the nail rod 2 when the two sides of the nail rod 2 along the second direction cooperate with the clamping jaw assembly 3 so that the nail rod 2 can move relative to the first clamping jaw portion 31 and the second clamping jaw portion 32.

[0054] For example, in Figure 4 and Figure 5 In the example, the clamping jaw assembly 3 is arranged at the lower part of the main body 1, and the first clamping jaw part 31 and the second clamping jaw part 32 are respectively located on the opposite sides of the nail rod 2, and the first clamping jaw part 31 and the second clamping jaw part 32 are roughly in the shape of claws after matching. During the process of the nail rod 2 rotating along the central axis of the nail rod 2, when the two sides of the nail rod 2 along the first direction are respectively opposite to the first clamping jaw part 31 and the second clamping jaw part 32, the distance between the first clamping jaw part 31 and the second clamping jaw part 32 is relatively close, so that the nail rod 2 can be clamped (such as Figure 4 When the two sides of the nail rod 2 along the second direction are respectively opposite to the first clamping claw portion 31 and the second clamping claw portion 32, the first clamping claw portion 31 and the second clamping claw portion 32 release the nail rod 2 so that the nail rod 2 can move up and down relative to the first clamping claw portion 31 and the second clamping claw portion 32 (as shown in FIG. Figure 5 shown).

[0055] During the process of the nail machine 100 installing the sealing nail 200 to the injection hole (not shown in the figure), when the nail rod 2 is rotated along the central axis of the nail rod 2 until the short diameter of the nail rod 2 (that is, the two sides of the nail rod 2 along the first direction) is located between the first clamping claw part 31 and the second clamping claw part 32, there is a gap between the lower end surface of the nail rod 2 and the upper side surface of the lower end of the first clamping claw part 31, and there is a gap between the lower end surface of the nail rod 2 and the upper side surface of the lower end of the second clamping claw part 32. The sealing nail 200 can be moved between the lower end of the nail rod 2 and the upper side surface of the lower end of the clamping claw assembly 3 under the action of other components cooperating with the nail machine 100, so as to clamp the sealing nail 200 through the clamping claw assembly 3, and at the same time, the upper surface of the sealing nail 200 is stopped against the lower end surface of the nail rod 2. When the nail rod 2 rotates along the central axis of the nail rod 2 until the long diameter of the nail rod 2 (that is, the two sides of the nail rod 2 along the second direction) is located between the first clamping jaw part 31 and the second clamping jaw part 32, the clamping jaw assemblies 3 move away from each other to release the nail rod 2 and the sealing nail 200, and then the nail rod 2 continues to move downward to push the sealing nail 200 and the injection hole to complete the assembly.

[0056] In this way, by setting the width of the nail rod 2 in the first direction to be smaller than the width of the nail rod 2 in the second direction, the distance between the first clamping claw part 31 and the second clamping claw part 32 can be adjusted by rotating the nail rod 2, so that the nail rod 2 cooperates with the first clamping claw part 31 and the second clamping claw part 32, thereby facilitating the adjustment and control of the clamping claw assembly 3 to clamp or release the nail rod 2, thereby facilitating the movement of the nail rod 2, facilitating the nail rod 2 to push the sealing nail 200 to assemble with the injection hole, and improving the performance of the nail machine 100. In addition, the nail machine 100 has a simple structure and is easy to use, thereby facilitating the rapid assembly of the sealing nail 200.

[0057] According to the nailing machine 100 of the present invention, through the structural setting of the nailing rod 2, it is convenient to adjust and control the clamping claw assembly 3 to clamp or release the nailing rod 2 by rotating the nailing rod 2, thereby facilitating the movement of the nailing rod 2 and facilitating the nailing rod 2 to push the sealing nail 200 to assemble with the injection hole, thereby improving the performance of the nailing machine 100. In addition, the nailing rod 2 has a simple structure and is easy to produce, thereby improving the production rate of the nailing rod 2. In addition, the nailing machine 100 has a simple structure and is easy to use, thereby facilitating the rapid assembly of the sealing nail 200 and improving the production efficiency of the battery.

[0058] According to some embodiments of the present invention, referring to Figure 4 and Figure 5 In the process of the nail rod 2 rotating from the two sides along the first direction to the two sides along the second direction of the nail rod 2, the first clamping claw portion 31 and the second clamping claw portion 32 move away from each other. Figure 4 and Figure 5In the example, when the nail rod 2 rotates from the two sides along the short diameter of the nail rod 2 to the two sides along the long diameter of the nail rod 2, the nail rod 2 pushes the first clamping claw part 31 and the second clamping claw part 32 away from each other, so that the distance between the first clamping claw part 31 and the second clamping claw part 32 increases. On the contrary, when the nail rod 2 rotates from the two sides along the long diameter of the nail rod 2 to the two sides along the short diameter of the nail rod 2, the first clamping claw part 31 and the second clamping claw part 32 approach each other, so that the distance between the first clamping claw part 31 and the second clamping claw part 32 decreases. Such a configuration facilitates the control of the first clamping claw part 31 and the second clamping claw part 32 to approach or move away from each other through the nail rod 2, thereby facilitating the clamping claw assembly 3 to clamp the nail rod 2 or release the nail rod 2, and further facilitating the nail machine 100 to control the installation of the sealing nail 200, effectively ensuring the normal use of the nail machine 100. Moreover, the difficulty of controlling the first clamping jaw portion 31 and the second clamping jaw portion 32 to move closer to or farther away from each other is reduced, thereby reducing the difficulty of using the clamping jaw assembly 3, simplifying the structure of the nailing machine 100, and further improving the convenience of using the nailing machine 100.

[0059] According to some embodiments of the present invention, the first direction and the second direction are orthogonal to the central axis of the nail rod 2. The first direction is perpendicular to the central axis of the nail rod 2, the second direction is perpendicular to the central axis of the nail rod 2, and the first direction is perpendicular to the second direction. With such a configuration, the cross section of the nail rod 2 can be configured to be a regular ellipse, rhombus, or oblong, etc., thereby further reducing the structural difficulty of the nail rod 2, and further increasing the production rate of the nail rod 2. In addition, when the nail rod 2 rotates 90°, it rotates from both sides of the first direction to both sides of the second direction, thereby facilitating the control of the use operation of the nail rod 2 by the nail machine 100, and thereby facilitating the use of the nail machine 100.

[0060] Optionally, the cross-sectional shape of the nail rod 2 is an ellipse or an oblong. For example, when the cross-sectional shape of the nail rod 2 is an ellipse, while ensuring that the first clamping claw portion 31 and the second clamping claw portion 32 can be moved closer to or farther from each other, the smoothness of the outer peripheral surface of the nail rod 2 is improved, thereby facilitating the smooth rotation of the nail rod 2, improving the smoothness of the rotation of the nail rod 2 along the central axis of the nail rod 2, and thus improving the performance of the nail rod 2. When the cross-sectional shape of the nail rod 2 is an oblong, while ensuring that the first clamping claw portion 31 and the second clamping claw portion 32 can be moved closer to or farther from each other, the structure of the nail rod 2 is simplified, thereby reducing the difficulty of producing the nail rod 2, thereby helping to increase the production rate of the nail rod 2 and also reducing the production cost of the nail rod 2.

[0061] According to some embodiments of the present invention, referring to Figure 4The jaw assembly 3 further includes a jaw body 33, which is arranged on the main body 1. The jaw body 33 is movable relative to the main body 1 along the central axis of the nail rod 2. An installation space 331 is formed on the jaw body 33. The first jaw portion 31 and the second jaw portion 32 are both arranged in the installation space 331. The nail rod 2 passes through the installation space 331. The first jaw portion 31 and the second jaw portion 32 are movable relative to the jaw body 33 in the direction close to the nail rod 2 and away from the nail rod 2.

[0062] For example, in Figure 4 In the example, the clamp body 33 is arranged at the lower part of the main body 1, and the installation space 331 is formed in the clamp body 33. The cross section of the installation space 331 is roughly in an inverted "U" shape. The nail rod 2 passes through the upper side surface of the clamp body 33 and the inner wall of the installation space 331 in the up-down direction. The first clamp part 31 and the second clamp part 32 can move in the installation space 331 in the direction of approaching and moving away from the nail rod 2. In this way, the clamp body 33 can protect the first clamp part 31 and the second clamp part 32, thereby preventing the first clamp part 31 and the second clamp part 32 from being damaged, thereby extending the service life of the first clamp part 31 and the second clamp part 32. In addition, the clamp body 33 helps the nail rod 2 to be used in conjunction with the first clamp part 31 and the second clamp part 32, thereby helping the nail machine 100 to be used normally. In addition, the clamp body 33 is movable in the up and down direction relative to the main body 1 , that is, the clamp body 33 can move up and down synchronously with the nail rod 2 to drive the sealing nail 200 to move, thereby facilitating the installation of the sealing nail 200 .

[0063] According to some embodiments of the present invention, from the reference Figure 4 The clamping jaw assembly 3 further includes at least one first elastic member 34 and at least one second elastic member 35. Specifically, the first elastic member 34 is disposed between the inner wall of the installation space 331 and the first clamping jaw portion 31, and the first elastic member 34 often pushes the first clamping jaw portion 31 to stop against the nail rod 2. The second elastic member 35 is disposed between the inner wall of the installation space 331 and the second clamping jaw portion 32, and the second elastic member 35 often pushes the second clamping jaw portion 32 to stop against the nail rod 2.

[0064] For example, in Figure 4In the example, two first elastic members 34 are provided, and the two first elastic members 34 are spaced apart in the up-down direction. The left end of the first elastic member 34 abuts against the left side wall of the installation space 331, and the right end of the first elastic member 34 abuts against the left side surface of the first clamping claw portion 31. Two second elastic members 35 are provided, and the two second elastic members 35 are spaced apart in the up-down direction. The right end of the second elastic member 35 abuts against the right side wall of the installation space 331, and the left end of the second elastic member 35 abuts against the right side surface of the second clamping claw portion 32. In the process of the nail rod 2 rotating from the two sides of the short diameter to the two sides of the long diameter of the nail rod 2, the nail rod 2 pushes the first clamping claw portion 31 and the second clamping claw portion 32 away from each other, and in this process, the first elastic member 34 and the second elastic member 35 are gradually compressed. When the nail rod 2 rotates from the two sides of the long diameter to the two sides of the short diameter of the nail rod 2, the first elastic member 34 and the second elastic member 35 gradually rebound, and the first elastic member 34 can push the first clamping claw part 31 to gradually move in the direction close to the nail rod 2, and the second elastic member 35 can push the second clamping claw part 32 to gradually move in the direction close to the nail rod 2. With such a configuration, the use and operation of the nailing machine 100 is simple, and it is convenient to push the first clamping claw part 31 to move in the direction close to the nail rod 2 through the first elastic member 34, and it is also convenient to push the second clamping claw part 32 to move in the direction close to the nail rod 2 through the second elastic member 35, so that the first clamping claw part 31 and the second clamping claw part 32 clamp the nail rod 2, thereby helping to improve the operating speed of the nailing machine 100 and helping to improve the working efficiency of the nailing machine 100. In addition, the first elastic member 34 and the second elastic member 35 are simple in structure, thereby simplifying the structure of the nailing machine 100 and reducing the production cost and use cost of the nailing machine 100. For example, the first elastic member 34 and the second elastic member 35 can both be springs.

[0065] According to some embodiments of the present invention, referring to Figure 4 At least one first installation groove 3311 is formed on the inner wall surface of the installation space 331, and a first matching groove 311 is formed on the side surface of the first clamping claw portion 31 facing the first elastic member 34. Both ends of the first elastic member 34 are respectively matched in the first installation groove 3311 and the first matching groove 311. Figure 4In the example, the first installation groove 3311 is formed on the left side wall of the installation space 331, the first matching groove 311 is formed on the left side wall of the first clamping claw portion 31, and two first installation grooves 3311 and first matching grooves 311 are provided at intervals in the up-down direction. The left end of the first elastic member 34 is inserted into the first installation groove 3311, and the left end of the first elastic member 34 abuts against the bottom wall of the first installation groove 3311. The outer peripheral surface of the left part of the first elastic member 34 abuts against the side wall of the first installation groove 3311. The right end of the first elastic member 34 is inserted into the first matching groove 311, and the right end of the first elastic member 34 abuts against the bottom wall of the first matching groove 311. In this way, the first installation groove 3311 and the first matching groove 311 can be used to accommodate the first elastic member 34, so that the first elastic member 34 is installed on the clamping claw body 33. Moreover, the side wall of the first mounting groove 3311 can limit the left part of the first elastic member 34, so that the first elastic member 34 is not easy to deflect during the process of being compressed or restoring the deformation, thereby improving the use stability of the first elastic member 34. In addition, the first mounting groove 3311 and the first matching groove 311 both have a positioning function for the first elastic member 34, so as to facilitate the rapid assembly of the first elastic member 34 with the first mounting groove 3311 and the first matching groove 311, and also improve the matching stability of the first elastic member 34 with the clamp body 33 and the first clamp portion 31.

[0066] According to other embodiments of the present invention, Figure 4 At least one second installation groove 3312 is formed on the inner wall surface of the installation space 331, and a second matching groove 321 is formed on the side surface of the second clamping claw portion 32 facing the second elastic member 35. The two ends of the second elastic member 35 are respectively matched in the second installation groove 3312 and the second matching groove 321. Figure 4In the example, the second mounting groove 3312 is formed on the right side wall of the mounting space 331, the second matching groove 321 is formed on the right side wall of the second clamping claw portion 32, two second mounting grooves 3312 and second matching grooves 321 are arranged at intervals in the up-down direction, the right end of the second elastic member 35 is inserted into the second mounting groove 3312, the right end of the second elastic member 35 abuts against the bottom wall of the second mounting groove 3312, the outer peripheral surface of the right part of the second elastic member 35 abuts against the side wall of the second mounting groove 3312, the left end of the second elastic member 35 is inserted into the second matching groove 321, and the left end of the second elastic member 35 abuts against the bottom wall of the second matching groove 321. With such a configuration, the second mounting groove 3312 and the second matching groove 321 can be used to accommodate the second elastic member 35, so that the second elastic member 35 is installed on the clamping claw body 33. Moreover, the side wall of the second mounting groove 3312 can limit the right part of the second elastic member 35, so that the second elastic member 35 is not easy to swing during the process of being compressed or restoring the deformation, thereby improving the use stability of the second elastic member 35. In addition, the second mounting groove 3312 and the second matching groove 321 both have a positioning function for the second elastic member 35, so as to facilitate the rapid assembly of the second elastic member 35 with the second mounting groove 3312 and the second matching groove 321, and also improve the matching stability of the second elastic member 35 with the clamp body 33 and the second clamp part 32.

[0067] According to some further embodiments of the present invention, Figure 4 At least one first installation groove 3311 is formed on the inner wall surface of the installation space 331, and a first matching groove 311 is formed on the side surface of the first clamping claw portion 31 facing the first elastic member 34, and the two ends of the first elastic member 34 are respectively matched in the first installation groove 3311 and the first matching groove 311. At the same time, at least one second installation groove 3312 is formed on the inner wall surface of the installation space 331, and a second matching groove 321 is formed on the side surface of the second clamping claw portion 32 facing the second elastic member 35, and the two ends of the second elastic member 35 are respectively matched in the second installation groove 3312 and the second matching groove 321.

[0068] In this way, the side wall of the first mounting groove 3311 can limit the left part of the first elastic member 34, and the side wall of the second mounting groove 3312 can limit the right part of the second elastic member 35, so that the first elastic member 34 is not easy to deflect during the process of being compressed or restoring the deformation, and the second elastic member 35 is not easy to deflect during the process of being compressed or restoring the deformation, thereby improving the use stability of the first elastic member 34 and the second elastic member 35. In addition, the first installation groove 3311 and the first matching groove 311 both have the function of installing and positioning the first elastic member 34, so as to facilitate the rapid assembly of the first elastic member 34 with the first installation groove 3311 and the first matching groove 311, and also improve the stable coordination of the first elastic member 34 with the clamp body 33 and the first clamp part 31. The second installation groove 3312 and the second matching groove 321 both have the function of installing and positioning the second elastic member 35, so as to facilitate the rapid assembly of the second elastic member 35 with the second installation groove 3312 and the second matching groove 321, and also improve the stable coordination of the second elastic member 35 with the clamp body 33 and the second clamp part 32, thereby improving the assembly speed of the nailing machine 100 and also improving the stability of the use of the nailing machine 100. This helps the nailing machine 100 to be used normally for a long time.

[0069] According to some embodiments of the present invention, referring to Figure 4 At least one first rolling member 36 is provided between the nail rod 2 and the first clamping portion 31. When the nail rod 2 rotates, the nail rod 2 drives the first clamping portion 31 to move in a direction close to the nail rod 2 and away from the nail rod 2 through the first rolling member 36; and / or, at least one second rolling member 37 is provided between the nail rod 2 and the second clamping portion 32. When the nail rod 2 rotates, the nail rod 2 drives the second clamping portion 32 to move in a direction close to the nail rod 2 and away from the nail rod 2 through the second rolling member 37.

[0070] For example, in Figure 4In the example, two first rolling members 36 and two second rolling members 37 are arranged at intervals in the vertical direction, the first rolling member 36 is opposite to the first elastic member 34 in the left-right direction, and the second rolling member 37 is opposite to the second elastic member 35 in the left-right direction. The first rolling member 36 and the second rolling member 37 are arranged in the following situations: First, at least one first rolling member 36 that can roll is arranged only between the nail rod 2 and the first clamping claw part 31, and when the nail rod 2 rotates, the nail rod 2 drives the first clamping claw part 31 to move in the direction close to the nail rod 2 and away from the nail rod 2 through the first rolling member 36. Second, at least one second rolling member 37 that can roll is arranged only between the nail rod 2 and the second clamping claw part 32, and when the nail rod 2 rotates, the nail rod 2 drives the second clamping claw part 32 to move in the direction close to the nail rod 2 and away from the nail rod 2 through the second rolling member 37. Third, at least one first rolling member 36 is provided between the nail rod 2 and the first clamping claw portion 31. When the nail rod 2 rotates, the nail rod 2 drives the first clamping claw portion 31 to move in the direction close to the nail rod 2 and away from the nail rod 2 through the first rolling member 36. At the same time, at least one second rolling member 37 is provided between the nail rod 2 and the second clamping claw portion 32. When the nail rod 2 rotates, the nail rod 2 drives the second clamping claw portion 32 to move in the direction close to the nail rod 2 and away from the nail rod 2 through the second rolling member 37.

[0071] With such arrangement, during the rotation of the nail rod 2, the first rolling member 36 and the second rolling member 37 also roll together, thereby reducing the friction between the first clamping claw portion 31 and the second clamping claw portion 32 and the nail rod 2 by providing the first rolling member 36 and the second rolling member 37, which is beneficial to the rotation of the nail rod 2, further improving the smoothness of the rotation of the nail rod 2, and thus helping to increase the rotation rate of the nail rod 2, so as to facilitate the first clamping claw portion 31 and the second clamping claw portion 32 to move quickly in the direction close to the nail rod 2 and away from the nail rod 2, thereby improving the working efficiency of the nail machine 100. Moreover, it is also beneficial to the normal use of the clamping claw assembly 3, thereby facilitating the long-term and stable use of the nail machine 100.

[0072] According to some embodiments of the present invention, referring to Figure 4 A first groove 312 is formed on the surface of the first clamping claw portion 31 facing the first rolling element 36. A portion of the first rolling element 36 fits in the first groove 312, and a side of the first rolling element 36 away from the first clamping claw portion 31 abuts against the nail rod 2. Figure 4In the example, the first groove 312 is formed on the right side of the first clamping claw portion 31, and the cross section of the first groove 312 is roughly arc-shaped. A portion of the first rolling member 36 close to the first clamping claw portion 31 is fitted in the first groove 312, and the outer peripheral surface of the first rolling member 36 is matched with the side wall of the first groove 312. The first rolling member 36 can roll in the first groove 312, and two first grooves 312 are provided at intervals along the vertical direction. In this way, the first groove 312 can accommodate a portion of the first rolling member 36, so that during the rolling process of the first rolling member 36, the first rolling member 36 is not easy to roll out of the first groove 312, thereby improving the use stability of the first rolling member 36. Moreover, through the cooperation of the first clamping claw portion 31 and the nail rod 2, the first rolling member 36 can be clamped between the first clamping claw portion 31 and the nail rod 2, which improves the cooperation stability of the first rolling member 36 and the first groove 312, and further improves the use stability of the first rolling member 36. In addition, the first groove 312 has a positioning function for the first rolling member 36 , which is beneficial for the quick assembly of the first rolling member 36 and the first clamping claw portion 31 .

[0073] According to some further embodiments of the present invention, Figure 4 A second groove 322 is formed on the surface of the second clamping claw portion 32 facing the second rolling element 37. A portion of the second rolling element 37 fits in the second groove 322. The side of the second rolling element 37 away from the second clamping claw portion 32 abuts against the nail rod 2. Figure 4 In the example, the second groove 322 is formed on the left side of the second clamping claw portion 32, and the cross section of the second groove 322 is roughly arc-shaped. A part of the second rolling member 37 close to the second clamping claw portion 32 is matched in the second groove 322, and the outer peripheral surface of the second rolling member 37 is matched with the side wall of the second groove 322. The second rolling member 37 can roll in the first groove 312, and two second grooves 322 are provided at intervals along the vertical direction. In this way, the second groove 322 can accommodate a part of the second rolling member 37, so that during the rolling process of the second rolling member 37, the second rolling member 37 is not easy to roll out of the second groove 322, thereby improving the use stability of the second rolling member 37. Moreover, through the cooperation between the second clamping claw portion 32 and the nail rod 2, the second rolling member 37 can be clamped between the second clamping claw portion 32 and the nail rod 2, which improves the cooperation stability between the second rolling member 37 and the second groove 322, and further improves the use stability of the second rolling member 37. In addition, the second groove 322 has a positioning function for the second rolling element 37 , which is beneficial for the rapid assembly of the second rolling element 37 and the second clamping claw portion 32 .

[0074] According to some further embodiments of the present invention, Figure 4A first groove 312 is formed on the surface of the first jaw portion 31 facing the first rolling element 36, a part of the first rolling element 36 fits in the first groove 312, and a side of the first rolling element 36 away from the first jaw portion 31 abuts against the nail rod 2. At the same time, a second groove 322 is formed on the surface of the second jaw portion 32 facing the second rolling element 37, a part of the second rolling element 37 fits in the second groove 322, and a side of the second rolling element 37 away from the second jaw portion 32 abuts against the nail rod 2.

[0075] Thus, the first groove 312 can accommodate a part of the first rolling member 36, and the second groove 322 can accommodate a part of the second rolling member 37, so that during the rolling process of the first rolling member 36 and the second rolling member 37, the first rolling member 36 is not easy to roll out of the first groove 312, and the second rolling member 37 is not easy to roll out of the second groove 322, thereby improving the use stability of the first rolling member 36 and the second rolling member 37, and improving the use stability of the clamping jaw assembly 3. Moreover, through the cooperation between the first clamping jaw portion 31 and the nail rod 2, and the cooperation between the second clamping jaw portion 32 and the nail rod 2, the cooperation stability between the first rolling member 36 and the first groove 312 is improved, and the cooperation stability between the second rolling member 37 and the second groove 322 is improved, thereby further improving the use stability of the first rolling member 36 and the second rolling member 37. In addition, the first groove 312 has a positioning function for the first rolling member 36, and the second groove 322 has a positioning function for the second rolling member 37, so as to facilitate the rapid assembly of the first rolling member 36 and the first clamping portion 31, and also facilitate the rapid assembly of the second rolling member 37 and the second clamping portion 32, thereby improving the assembly efficiency of the clamping assembly 3.

[0076] According to some embodiments of the present invention, the first rolling member 36 is a ball; and / or, the second rolling member 37 is a ball. For example, the first rolling member 36 and the second rolling member 37 are configured as the following situations: First, the first rolling member 36 is a ball. Second, the second rolling member 37 is a ball. Third, the first rolling member 36 and the second rolling member 37 are both configured as balls. With such a configuration, the cross section of the ball is circular, thereby reducing the contact area between the first rolling member 36 and the plug rod 2, reducing the contact area between the second rolling member 37 and the plug rod 2, and further reducing the friction between the first rolling member 36 and the plug rod 2, reducing the friction between the second rolling member 37 and the plug rod 2, which is conducive to further improving the smoothness of the rotation of the plug rod 2.

[0077] Optionally, refer to Figure 6 and Figure 7The nailing machine 100 further includes a first motor 4, a screw rod 5, a vertical plate 6, a second motor 7 and a mounting plate 8. The first motor 4, the screw rod 5, the vertical plate 6 and the mounting plate 8 are all arranged on the main body 1, the first motor 4 is connected to the upper end of the screw rod 5, the screw rod 5 is threadedly connected to the vertical plate 6, the vertical plate 6 is connected to the mounting plate 8, the second motor 7 is arranged on the mounting plate 8, and the upper end of the nailing rod 2 is connected to the second motor 7. During the operation of the nailing machine 100, the first motor 4 can drive the vertical plate 6 to reciprocate in the up and down directions through the screw rod 5, and then the vertical plate 6 drives the second motor 7 and the nailing rod 2 to move up and down through the mounting plate 8. The second motor 7 can drive the nailing rod 2 to rotate along the central axis of the nailing rod 2. With such a configuration, the nailing machine 100 has a simple structure and is easy to operate, thereby improving the performance of the nailing machine 100. In addition, the nailing machine 100 can simultaneously realize the movement of the nailing rod 2 in the up and down directions and the rotation of the nailing rod 2 along the central axis of the nailing rod 2, thereby facilitating the installation of the sealing nail 200 by the nailing machine 100 and helping to improve the installation efficiency of the nailing machine 100.

[0078] Optionally, refer to Figure 6 and Figure 7 The main body 1 is connected with a guide member 11, and the clamping jaw assembly 3 can move in the up and down direction relative to the guide member 11. The main body 1 is connected with a limit member 12, and the limit member 12 and the clamping jaw assembly 3 can be detachably matched. A third elastic member (not shown) is provided between the clamping jaw assembly 3 and the mounting plate 8, and the third elastic member is sleeved on the outer peripheral surface of the nail rod 2. For example, in Figure 6 and Figure 7 In the example, the side of the clamp body 33 close to the main body 1 is slidably matched with the side of the guide member 11 away from the main body 1, and the lower side surface of the clamp body 33 is detachably matched with the upper end surface of the limit member 12.

[0079] Therefore, during the downward movement of the mounting plate 8, the third elastic member pushes the clamping jaw assembly 3 to move downward together until the lower side of the clamping jaw body 33 abuts against the upper side of the limiter 12 to limit the clamping jaw assembly 3 from continuing to move downward. When the first clamping jaw portion 31 and the second clamping jaw portion 32 release the nail rod 2, the nail rod 2 can push the sealing nail 200 to continue to move downward until the sealing nail 200 is assembled, thereby facilitating the installation of the sealing nail 200 by the nailing machine 100 and improving the performance of the nailing machine 100. Moreover, the difficulty of operating the nailing machine 100 is also reduced. In addition, the guide member 11 has a guiding effect on the movement of the clamping jaw assembly 3, thereby improving the accuracy of the up and down movement of the clamping jaw assembly 3.

[0080] The working process of the nailing machine 100 of the present application is roughly as follows:

[0081] When the sealing nail 200 is clamped between the jaw assembly 3 and the lower end of the nail rod 2, the first motor 4 drives the screw rod 5 to move to drive the vertical plate 6 to move downward, and the vertical plate 6 drives the mounting plate 8 to move downward together, thereby driving the second motor 7 and the nail rod 2 to descend as a whole. During this process, the third elastic member pushes the jaw assembly 3 to move downward together.

[0082] When a part of the sealing nail 200 is inserted into the injection hole, the first motor 4 stops working, and the second motor 7 drives the nail rod 2 to rotate 90° along the central axis of the nail rod 2. The long diameter of the nail rod 2 is located between the first clamping jaw part 31 and the second clamping jaw part 32. The first clamping jaw part 31 and the second clamping jaw part 32 release the nail rod 2 to release the sealing nail 200.

[0083] The first motor 4 continues to work, driving the nail rod 2 to move downward. At this time, the limit piece 12 limits the downward movement of the clamping jaw assembly 3. The nail rod 2 presses the sealing nail 200 downward so that the sealing nail 200 is installed in the injection hole, and the entire nail insertion process is completed.

[0084] According to the sealing nail 200 of the second embodiment of the present invention, Figure 7 and Figure 8 The sealing nail 200 is used to detachably cooperate with the clamping jaw assembly 3 of the nailing machine 100 according to the first embodiment of the present invention.

[0085] According to the sealing nail 200 of the present invention, by adopting the above-mentioned nailing machine 100, the sealing nail 200 and the injection hole can be quickly assembled, thereby improving the assembly efficiency of the sealing nail 200 and the battery.

[0086] According to some embodiments of the present invention, referring to Fig. 9 The sealing pin 200 includes a first sealing section 201 and a second sealing section 202 .

[0087] Specifically, the second sealing section 202 is connected to one side of the first sealing section 201 in the thickness direction, and a step portion 203 is provided between the second sealing section 202 and the first sealing section 201. When both sides of the nail rod 2 of the nailing machine 100 along the first direction cooperate with the clamping jaw assembly 3, the first clamping jaw portion 31 and the second clamping jaw portion 32 of the clamping jaw assembly 3 clamp the sealing nail 200 through the step portion 203, and when both sides of the nail rod 2 along the second direction cooperate with the clamping jaw assembly 3, the first clamping jaw portion 31 and the second clamping jaw portion 32 are separated from the sealing nail 200.

[0088] For example, in Fig. 9In the example, the lower side of the first sealing section 201 is connected to the upper side of the second sealing section 202, the first sealing nail 200 is located between the plug nail rod 2 and the first clamping claw portion 31 and the second clamping claw portion 32, and the upper side of the first sealing nail 200 is abutted against the lower end surface of the plug nail rod 2. In this way, the clamping claw assembly 3 cooperates with the first sealing section 201 through the step portion 203, so that the clamping claw assembly 3 is convenient for clamping and releasing the sealing nail 200, thereby improving the installation efficiency of the sealing nail 200. In addition, it is also conducive to the rapid assembly of the sealing nail 200. In addition, the sealing nail 200 has a simple structure, which improves the production efficiency of the sealing nail 200.

[0089] According to some embodiments of the present invention, referring to Fig. 9 The second sealing section 202 includes a connecting section 2021 and a guiding section 2022. One end of the connecting section 2021 is connected to the first sealing section 201. The guiding section 2022 is connected to the other end of the connecting section 2021. The cross-sectional area of ​​the end of the guiding section 2022 away from the connecting section 2021 is smaller than the cross-sectional area of ​​the end of the guiding section 2022 connected to the connecting section 2021. For example, Fig. 9 In the example, the upper end of the connecting section 2021 is connected to the lower side of the first sealing section 201, and the upper end of the guide section 2022 is connected to the lower end of the connecting section 2021. With such a configuration, the cross section of the guide section 2022 is smaller, so that it is convenient to insert the guide section 2022 into the injection hole and preliminarily position the injection hole, so as to facilitate the insertion of the second sealing section 202 into the injection hole, thereby facilitating the assembly efficiency of the sealing nail 200 and the injection hole of the battery, and also improving the yield of the sealing nail 200. In addition, the sealing nail 200 has a simple structure, which improves the production rate of the sealing nail 200, reduces the production cost of the sealing nail 200, and avoids the sealing nail 200 from getting stuck during the feeding process, thereby improving the feeding speed.

[0090] According to some embodiments of the present invention, referring to Fig. 9 , the cross-sectional area of ​​the connecting section 2021 remains unchanged. Fig. 9 In the example of , the connecting section 2021 is roughly cylindrical. Such a configuration facilitates the sealing cooperation between the outer peripheral surface of the connecting section 2021 and the side wall of the injection hole, thereby improving the sealing performance of the sealing nail 200 and the injection hole, and preventing the liquid from flowing out of the injection hole. In addition, the structure of the connecting section 2021 is simple, which helps to increase the production rate of the second sealing section 202. In addition, the friction between the sealing nail 200 and the injection hole is small, so that the plugging operation is simple.

[0091] According to some embodiments of the present invention, referring to Fig. 9, the first sealing section 201 is a sheet structure. With such a configuration, the first sealing section 201 has a simple structure and is easy to produce, thereby helping to increase the production rate of the first sealing section 201. In addition, the material usage of the first sealing section 201 is also reduced, thereby reducing the production cost of the first sealing section 201, and further reducing the production cost of the sealing nail 200.

[0092] According to some optional embodiments of the present invention, referring to Fig.10 The first sealing section 201 is provided with a connecting protrusion 204, which is connected to one side of the first sealing section 201 in the thickness direction. The second sealing section 202 is formed with a receiving cavity 2023, which penetrates the side surface of the second sealing section 202 facing the first sealing section 201, and the connecting protrusion 204 is located in the receiving cavity 2023. For example, in Fig.10 In the example, the upper end surface of the connecting protrusion 204 is connected to the upper side surface of the first sealing section 201, and the second sealing section 202 is arranged around the outer peripheral surface of the connecting protrusion 204, and the outer peripheral surface of the connecting protrusion 204 contacts the inner wall of the accommodating cavity 2023. With such a configuration, the connecting protrusion 204 has a simple structure, low production and processing difficulty, and is easy to use. In addition, the second sealing section 202 can be connected to the first sealing section 201 and the connecting protrusion 204 as a whole, which facilitates the use of the sealing nail 200, simplifies the use steps, and improves the use performance. Moreover, the connection between the second sealing section 202 and the connecting protrusion 204 is strengthened, and the connection is firm, thereby strengthening the connection between the second sealing section 202 and the connecting protrusion 204 and improving the integrity of the sealing nail 200.

[0093] Optionally, refer to Fig.10 The connecting protrusion 204 includes a first connecting protrusion section 2041 and a second connecting protrusion section 2042. The upper end of the first connecting protrusion section 2041 is connected to the lower side of the first sealing section 201, and the upper end of the second connecting protrusion section 2042 is connected to the lower end of the first connecting protrusion section 2041. The outer peripheral surface of the second connecting protrusion section 2042 protrudes from the outer peripheral surface of the first connecting protrusion section 2041. The cross-sectional area of ​​the second connecting section 2021 gradually decreases as the second connecting protrusion section 2042 moves away from the first connecting protrusion section 2041. For example, in Fig.10In the example, the cross section of the first connecting protrusion section 2041 is roughly rectangular, and the cross section of the second connecting protrusion section 2042 is roughly an inverted isosceles trapezoid. In this way, the outer peripheral surface of the second connecting protrusion section 2042 is in close contact with the side wall of the accommodating cavity 2023, so that after the connecting protrusion 204 and the second sealing section 202 are assembled, the second connecting protrusion section 2042 has a radially outward supporting force on the second sealing section 202, so that the second sealing section 202 is not easy to fall off from the connecting protrusion 204, thereby improving the connection stability between the connecting protrusion 204 and the second sealing section 202, and improving the long-term use stability of the sealing nail 200.

[0094] Optionally, the first sealing section 201 and the connecting protrusion 204 are both plastic parts, and the second sealing section 202 is a rubber part. Plastic parts are easy to mold and have low cost, thereby increasing the production rate of the first sealing section 201 and the connecting protrusion 204, and also reducing the production cost of the first sealing section 201 and the connecting protrusion 204. The rubber part has good elasticity, and the rubber part has properties such as oil resistance and wear resistance, which improves the sealing performance of the connection between the sealing nail 200 and the injection hole, thereby extending the service life of the second sealing section 202. For example, the diameter of the first sealing section 201 can be 6 mm, and the diameter of the second sealing section 202 can be 4 mm. Of course, it can also be designed according to the actual use of the injection hole.

[0095] Optionally, the second sealing section 202, the first sealing section 201 and the connecting protrusion 204 may be an integrally formed part, thereby facilitating the transportation and use of the sealing nail 200 and improving the use performance of the sealing nail 200.
