[0038] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model will be described in detail below.

[0039] Reference is made below to Figures 1 - 5 describe the plug nail device 100 according to the embodiments of the present utility model.

[0040] Referring to Figures 1 - 5 As shown, the plug nail device 100 according to the first aspect embodiment of the present utility model includes: a first driving mechanism 10 and a plug nail rod 20. The plug nail rod 20 is connected to the first driving mechanism 10 so that it can rotate under the drive of the first driving mechanism 10. One end of the plug nail rod 20 far from the first driving mechanism 10 is a plug nail end 21. An installation groove 22 is provided at the plug nail end 21 for accommodating the head of the injection hole nail 83, so that the injection hole nail 83 can rotate with the plug nail rod 20.

[0041] Specifically, traditional plug nail devices generally perform plugging under normal pressure conditions. During the process of using the normal pressure plugging process, when the plug nail rod sucks the glue nail and aligns it with the injection hole for plugging, due to the lack of electrolyte for lubrication, plugging is difficult, resulting in problems such as low plugging efficiency and insufficient plugging yield.

[0042] Therefore, it is necessary to optimize the plug device 100. The first driving mechanism 10 in the plug device 100 can provide driving force for the rotation of the plug rod 20. For example, the first driving mechanism 10 can include a servo motor. Moreover, an installation groove 22 is formed at the plug end 21 of the plug rod 20. The setting of the installation groove 22 can provide an installation position for the head of the liquid injection hole nail 83. The head of the liquid injection hole nail 83 extends into the installation groove 22, and the liquid injection hole nail 83 is in interference fit with the installation groove 22, which can directly connect the liquid injection hole nail 83 with the installation groove 22, so that the connection between the plug rod 20 and the liquid injection hole nail 83 can be more stable and firm, and the loosening of the liquid injection hole nail 83 when it is inserted into the liquid injection hole can also be avoided.

[0043] When the first driving mechanism 10 works, since the plug rod 20 is connected to the first driving mechanism 10, the first driving mechanism 10 can drive the plug rod 20 to rotate. Further, since the head of the liquid injection hole nail 83 is connected to the plug rod 20, when the plug rod 20 rotates, it can drive the liquid injection hole nail 83 to rotate, which is convenient for the liquid injection hole nail 83 to be inserted into the liquid injection hole and can also improve the plugging yield of the liquid injection hole nail 83.

[0044] Thus, in the plug device 100, the first driving mechanism 10 can drive the plug rod 20 to rotate, and the head of the liquid injection hole nail 83 is connected to the plug rod 20, so that the liquid injection hole nail 83 can rotate synchronously with the plug rod 20. Moreover, the head of the liquid injection hole nail 83 is in interference fit with the installation groove 22 of the plug rod 20, which can make the connection between the plug rod 20 and the liquid injection hole nail 83 more stable and firm, and the loosening of the liquid injection hole nail 83 when it is inserted into the liquid injection hole can also be avoided.

[0045] According to some embodiments of the present invention, as Figure 4 and Figure 5 shown, the installation groove 22 has a notch 221 and a bottom 222, and in the direction extending from the notch 221 to the bottom 222, the cross-sectional area of the installation groove 22 decreases.

[0046] Among them, during the process of the head of the liquid injection hole nail 83 extending into the installation groove 22, since the cross-sectional area of the installation groove 22 decreases in the direction extending from the notch 221 to the bottom 222, when the head of the liquid injection hole nail 83 starts to extend into the installation groove 22, since the notch 221 of the installation groove 22 is larger, it is convenient for the head of the liquid injection hole nail 83 to extend in. As the head of the liquid injection hole nail 83 extends in, the cross-sectional area of the installation groove 22 decreases, which can make the head of the liquid injection hole nail 83 fit more closely with the installation groove 22 gradually, thus improving the connection stability between the head of the liquid injection hole nail 83 and the installation groove 22.

[0047] According to some embodiments of the present invention, as Figure 5As shown, the plug rod 20 is provided with an exhaust passage 30, and the exhaust passage 30 communicates between the installation groove 22 and the external environment.

[0048] Among them, after the head of the liquid injection hole nail 83 is inserted into the installation groove 22, since a gap is formed between the head of the liquid injection hole nail 83 and the bottom 222 of the installation groove 22, during the process of inserting the head of the liquid injection hole nail 83 into the installation groove 22, the air in the installation groove 22 will be compressed, and it is easy to generate local high pressure at the gap. When the head of the liquid injection hole nail 83 is pulled out of the installation groove 22, it is easy to generate negative pressure at the gap, so that it is difficult to pull out the head of the liquid injection hole nail 83 from the installation groove 22. Since the exhaust passage 30 communicates between the installation groove 22 and the external environment, the installation groove 22 can be communicated with the external air, thereby preventing local high pressure or negative pressure from being generated when the head of the liquid injection hole nail 83 enters or exits the installation groove 22.

[0049] According to a specific embodiment of the present invention, as Figure 4 and Figure 5 shown, the exhaust passage 30 includes: an axial section 31 and a radial section 32. The installation groove 22 has a bottom 222. The axial section 31 communicates with the bottom 222, the radial section 32 communicates with the axial section 31, and the radial section 32 extends to the outer peripheral surface of the plug rod 20.

[0050] Specifically, the exhaust passage 30 is mainly composed of an axial section 31 and a radial section 32. The axial section 31 communicates with the bottom 222. The axial section 31 extends along the length direction of the plug rod 20, which can play a role in guiding air and can also prevent the accumulation of gas in the installation groove 22. Further, the radial section 32 communicates with the axial section 31, which can discharge the gas in the axial section 31 through the radial section 32, and can also facilitate the external air to flow into the axial section 31 through the radial section 32. In this way, high pressure or negative pressure can be avoided at the connection position between the head of the liquid injection hole nail 83 and the installation groove 22.

[0051] According to some embodiments of the present invention, the plug device 100 further includes: a frame 40, a mounting seat 41 and a guide sleeve assembly 50. The first driving mechanism 10 is arranged on the frame 40, the mounting seat 41 is arranged on the frame 40, the guide sleeve assembly 50 is arranged on the mounting seat 41, and the plug rod 20 with the liquid injection hole nail 83 selectively passes through the guide sleeve assembly 50.

[0052] Among them, the mounting seat 41 is arranged on the frame 40. The frame 40 can drive the mounting seat 41 to move in the horizontal, longitudinal and vertical directions. The horizontal direction is the left - right direction, the longitudinal direction is the front - back direction, and the vertical direction is the up - down direction. The guide sleeve assembly 50 is arranged on the mounting seat 41, so as to facilitate the movement of the guide sleeve assembly 50 along with the specific position of the liquid injection hole on the battery.

[0053] In addition, the plug pin rod 20 with the liquid injection hole pin 83 selectively penetrates the guide sleeve assembly 50. That is to say, when it is necessary to plug the liquid injection hole pin 83 into the liquid injection hole on the battery, the plug pin rod 20 will automatically penetrate the guide sleeve assembly 50 to reach the position of the liquid injection hole. When it is not necessary to plug the liquid injection hole pin 83 into the liquid injection hole on the battery, the plug pin rod 20 will automatically return to the initial position. In this way, the efficiency of the plugging device 100 for plugging the liquid injection hole pin 83 into the liquid injection hole can be improved.

[0054] According to some embodiments of the present invention, such as Figure 3 As shown, the guide sleeve assembly 50 includes: a first sliding mechanism 51 and a second sliding mechanism 52. The first sliding mechanism 51 and the second sliding mechanism 52 are slidably disposed on the mounting base 41. A first half guide sleeve 53 and a second half guide sleeve 54. The first half guide sleeve 53 is disposed on the first sliding mechanism 51, and the second half guide sleeve 54 is disposed on the second sliding mechanism 52. The first half guide sleeve 53 and the second half guide sleeve 54 are disposed opposite to each other, and the first half guide sleeve 53 and the second half guide sleeve 54 form a guiding channel 60. When the plug pin rod 20 with the liquid injection hole pin 83 penetrates the guiding channel 60, the first half guide sleeve 53 and the second half guide sleeve 54 move away from each other when being pressured by the liquid injection hole pin 83.

[0055] Among them, the first sliding mechanism 51 and the second sliding mechanism 52 are slidably disposed on the mounting base 41. Since the first half guide sleeve 53 is connected to the first sliding mechanism 51, the first half guide sleeve 53 slides with the first sliding mechanism 51. Similarly, the second half guide sleeve 54 is connected to the second sliding mechanism 52, so the second half guide sleeve 54 slides with the second sliding mechanism 52.

[0056] When it is necessary to plug the liquid injection hole pin 83 into the liquid injection hole on the battery, the plug pin rod 20 applies a certain pressure to the first half guide sleeve 53 and the second half guide sleeve 54, so that the first half guide sleeve 53 and the second half guide sleeve 54 move away from each other, which is convenient for the plug pin rod 20 to penetrate the guiding channel 60. In this way, it is convenient to adjust the opening and closing of the first half guide sleeve 53 and the second half guide sleeve 54, and thus it is convenient for the plug pin rod 20 to penetrate and retract.

[0057] According to the specific embodiments of the present invention, such as Figure 3As shown in the figure, the first sliding mechanism 51 includes: a first slider 511 and a first elastic member 512. The first slider 511 is slidably disposed on the mounting base 41, and the first elastic member 512 is abutted between the first slider 511 and the mounting base 41, so as to provide an elastic force for the first slider 511 to move towards the second sliding mechanism 52. The second sliding mechanism 52 includes: a second slider 521 and a second elastic member 522. The second slider 521 is slidably disposed on the mounting base 41, and the second elastic member 522 is abutted between the second slider 521 and the mounting base 41, so as to provide an elastic force for the second slider 521 to move towards the second sliding mechanism 52.

[0058] Specifically, both the first elastic member 512 and the second elastic member 522 can be set as springs. When the liquid injection hole on the battery is plugged with the liquid injection hole nail 83, the plugging nail rod 20 applies pressure to the first semiconductor sleeve 53 and the second semiconductor sleeve 54, which can cause the first slider 511 to compress the first elastic member 512, causing the first elastic member 512 to undergo elastic deformation to generate an elastic force. When the pressure of the plugging nail rod 20 on the first semiconductor sleeve 53 is withdrawn, the first elastic member 512 restores the elastic force and moves the first slider 511 towards the second sliding mechanism 52.

[0059] At the same time, the plugging nail rod 20 can cause the second slider 521 to compress the second elastic member 522, causing the second elastic member 522 to undergo elastic deformation to generate an elastic force. When the pressure of the plugging nail rod 20 on the second semiconductor sleeve 54 is withdrawn, the second elastic member 522 restores the elastic force and moves the second slider 521 towards the second sliding mechanism 52, thereby realizing the automatic closing of the first semiconductor sleeve 53 and the second semiconductor sleeve 54.

[0060] According to some embodiments of the present invention, as Figure 3 shown, the mounting base 41 includes: a connecting base 411 and a guiding base 412. The connecting base 411 is connected between the frame 40 and the guiding base 412. The guiding base 412 is provided with a sliding groove, and the first slider 511 and the second slider 521 are slidably disposed in the sliding groove. Both the connecting base 411 and the guiding base 412 are provided with through holes 413 for the plugging nail rod 20 to pass through.

[0061] Among them, the connecting base 411 is connected between the frame 40 and the guiding base 412, and the frame 40 can provide an installation position for the connecting base 411. The first slider 511 slides in the sliding groove, and the second slider 521 slides in the sliding groove. Thus, the first slider 511 and the second slider 521 slide relative to each other. Since the first semiconductor sleeve 53 is connected to the first slider 511 and the second semiconductor sleeve 54 is connected to the second slider 521, therefore, the first semiconductor sleeve 53 and the second semiconductor sleeve 54 can be simultaneously opened and closed.

[0062] In addition, both the connecting seat 411 and the guiding seat 412 are provided with through holes 413 for the plug pin rod 20 to pass through, which facilitates the plug pin rod 20 to pass through the connecting seat 411 and the guiding seat 412 in sequence to reach the liquid injection hole of the battery for plugging the liquid injection hole nail 83.

[0063] According to some embodiments of the present invention, the plugging device 100 further includes: a second driving mechanism 70 and an adapter bracket 71. The adapter bracket 71 is connected to the second driving mechanism 70. The adapter bracket 71 moves under the drive of the first driving mechanism 10, and the first driving mechanism 10 is installed on the adapter bracket 71.

[0064] Among them, the first driving mechanism 10 is installed on the adapter bracket 71, and the first driving mechanism 10 and the adapter bracket 71 form an integral body. Since the adapter bracket 71 is connected to the second driving mechanism 70, the adapter bracket 71 performs a lifting motion under the drive of the second driving mechanism 70. For example, the second driving mechanism 70 may include a servo motor, and the plug pin rod 20 is connected to the first driving mechanism 10 and can rotate. Since the first driving mechanism 10 is installed on the adapter bracket 71, the lifting motion and the rotational motion of the plug pin rod 20 can be realized.

[0065] According to some embodiments of the present invention, the plugging device 100 further includes: a position detector 80. The position detector 80 is used to detect the position information of the battery and the position information of the liquid injection hole of the battery. The position detector 80 is electrically connected to the first driving mechanism 10 and the second driving mechanism 70 respectively.

[0066] Among them, the setting of the position detector 80 can facilitate the measurement of the height of the liquid injection hole of the battery, and can also identify whether there is a liquid injection hole nail in the liquid injection hole of the battery, thereby improving the accuracy of the plugging device 100 for plugging the liquid injection hole nail 83 into the liquid injection hole.

[0067] In addition, the position detector 80 is electrically connected to the first driving mechanism 10 and the second driving mechanism 70 respectively, and can detect the angle of rotation of the first driving mechanism 10 driving the plug pin rod 20, and can also detect the height of the second driving mechanism 70 driving the plug pin rod 20 to lift.

[0068] According to some embodiments of the present invention, the position detector 80 includes: a laser sensor 81 and a CCD camera 82. The laser sensor 81 is used to detect the position information of the battery, the height information of the liquid injection hole of the battery, and whether there is a liquid injection hole nail 83. The CCD camera 82 is used to photograph the position of the liquid injection hole of the battery.

[0069] Specifically, the rack 40 moves to the position where the multi-point laser sensor 81 detects the battery, measures the distance to the height of the battery filling hole and identifies whether there is a filling hole nail 83 in the filling hole. At the same time, the external filling hole mechanism places the filling hole nail 83 into the guide sleeve assembly 50, compensates and moves to the position of the battery filling hole according to the distance measurement value of the multi-point laser sensor 81, takes a photo through the CCD camera 82, and the program finds the center of the filling hole to calculate the position compensation value of the filling hole nail 83.

[0070] Move to the position of the filling hole nail 83 according to the compensation value (Z direction) of the multi-point laser sensor 81 and the compensation values (X direction, Y direction) of the photo taken by the CCD camera 82. The second driving mechanism 70 drives the plug nail rod 20 to descend. At the same time, the first driving mechanism 10 drives the plug nail rod 20 to rotate. The plug nail rod 20 continues to move downward with the filling hole. The first slider 511 presses the first elastic member 512. At the same time, the second slider 521 presses the second elastic member 522. The first semi-guide sleeve 53 and the second semi-guide sleeve 54 open to the left and right respectively. The plug nail rod 20 smoothly passes through the guiding channel 60 with the filling nail. The filling nail contacts the filling hole for plugging. After the filling nail plugs the hole, it stops rotating and rises to the initial position to complete the plugging.
