[0031] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0032] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0033] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0034] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0036] The pin insertion module according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0037] like Figure 1 and Figure 2 As shown, the pin insertion module according to an embodiment of the present utility model includes: a pin suction assembly 10, a base 20, and a limiting member 30.

[0038] Specifically, the suction pin assembly 10 is used to pick up the sealing pin. A floating seat 21 that can elastically float along a first direction is provided on one side of the base 20. The suction pin assembly 10 is disposed on the floating seat 21. The base 20 can move along the first direction so that the suction pin assembly 10 can insert the sealing pin into the electrolyte filling hole of the battery. A limiting member 30 is disposed on the floating seat 21. The limiting member 30 is used to fit against the battery when the sealing pin is inserted into the electrolyte filling hole to a predetermined depth, so as to limit the insertion depth of the sealing pin.

[0039] In other words, such as Figure 1 and Figure 2 As shown, the nail insertion module according to this utility model embodiment is mainly applied to the nail insertion device 100. The nail insertion module mainly includes a nail suction assembly 10 and a base 20. The nail suction assembly 10 includes a nail suction seat 11 and a nail suction nozzle 12. The first end (e.g., the upper end) of the nail suction nozzle 12 is fixedly connected to the nail suction seat 11. The nail suction nozzle 12 is used to connect to a negative pressure generating device. By controlling the operation of the negative pressure generating device, the second end (e.g., the lower end) of the nail suction nozzle 12 can be controllably sucked up the sealing nail.

[0040] Specifically, such as Figure 5As shown, the base 20 is used to connect with the pin drive unit 75 (e.g., a cylinder). The pin drive unit 75 can drive the base 20 to move along a first direction, which is the same as the length direction of the sealing pin on the pin suction assembly 10 (i.e., the depth direction of the injection hole). When the length direction of the sealing pin on the pin suction assembly 10 is vertical, the first direction is the vertical direction. Figure 1 As shown, a floating seat 21 that can elastically float along a first direction is provided on one side of the base 20, and the nail suction assembly 10 is mounted on the floating seat 21. When inserting a nail, the nail insertion drive unit 75 drives the base 20 to move along the first direction, so that the nail suction assembly 10 moves along the first direction, thereby enabling the sealing nail sucked by the nail suction nozzle 12 to be inserted into the electrolyte filling hole of the battery.

[0041] Furthermore, such as Figure 1 and Figure 2 As shown, a limiting member 30 is fixedly connected to one side of the floating seat 21 near the second end of the suction nozzle 12. When the sealing pin is not inserted into the liquid injection hole, the limiting member 30 is spaced apart from the top of the battery; while when the sealing pin is inserted into the liquid injection hole to a predetermined depth, the limiting member 30 is in contact with the top of the battery.

[0042] During the insertion process, the insertion drive unit 75 drives the base 20 to move toward the battery. When the limiting member 30 is in contact with the top of the battery, the depth to which the sealing pin is inserted into the injection hole is the predetermined depth. If the base 20 continues to move toward the battery, the limiting member 30 will restrict the floating seat 21 from continuing to move toward the battery. Since the floating seat 21 can float elastically, the distance between the base 20 and the floating seat 21 will decrease during the movement of the base 20, while the pin suction assembly 10 on the floating seat 21 remains stationary relative to the battery.

[0043] Therefore, once the limiting member 30 is in contact with the top of the battery, it can prevent the suction pin assembly 10 from continuing to move toward the battery, thereby ensuring that the depth of the sealing pin inserted into the injection hole remains at the predetermined depth and will not be inserted further.

[0044] In other words, according to the embodiment of this utility model, during the insertion process, the pin module only needs to be controlled based on the height of the lowest battery to ensure that the limiting member 30 always stays in contact with the top of the battery, thereby effectively avoiding insufficient or excessive insertion depth of the sealing pin, and thus effectively improving the pin yield.

[0045] Therefore, according to the pin insertion module provided in this embodiment, by setting a limiting member 30 and a pin suction assembly 10 on the elastically floating seat 21, the pin insertion module can insert the sealing pin to a predetermined depth when inserting batteries of different heights. This effectively avoids the problem of the sealing pin being inserted too deeply or too insufficiently due to the size error of the battery, significantly improves the yield of pin insertion, and thus improves production efficiency and product quality.

[0046] According to one embodiment of the present invention, the pin module further includes: at least one guide rod 22, the guide rod 22 being fixedly connected to one of the base 20 and the floating seat 21, and the guide rod 22 being movably disposed in the other of the base 20 and the floating seat 21 along a first direction; and an elastic member 23, the elastic member 23 being disposed between the base 20 and the floating seat 21, and the elastic member 23 being sleeved on the guide rod 22.

[0047] Specifically, such as Figure 1 and Figure 2 As shown, the base 20 has a first side and a second side arranged opposite to each other in a first direction. A flange seat 25 for connecting to the output end of the pin drive unit 75 is fixedly connected to the first side of the base 20. The floating seat 21 is located on the second side of the base 20 and spaced apart from it. The base 20 and the floating seat 21 are movably connected together by one or more guide rods 22, allowing the floating seat 21 to move relative to the base 20 along the first direction. In this embodiment, the base 20 and the floating seat 21 are movably connected together by two guide rods 22, thereby ensuring the stability of the structure.

[0048] Specifically, the connection methods between the base 20 and the floating seat 21 include, but are not limited to, the following:

[0049] Case 1: The guide rod 22 extends along the first direction, one end of the guide rod 22 is fixedly connected to the floating seat 21, and the guide rod 22 is movably installed on the base 20 along the first direction;

[0050] Scenario 2: The guide rod 22 extends along the first direction, one end of the guide rod 22 is fixedly connected to the base 20, and the guide rod 22 is movably mounted on the floating seat 21 along the first direction.

[0051] In this embodiment, an elastic element 23 is provided between the base 20 and the floating seat 21. The elastic element 23 can be a spring, with one end of the spring abutting or fixedly connected to the floating seat 21 and the other end of the spring abutting or fixedly connected to the base 20. This allows the floating seat 21 to float elastically in a first direction, resulting in a simple structure. The number of elastic elements 23 can be the same as the number of guide rods 22, and the elastic elements 23 can be sleeved on the corresponding guide rods 22. This allows the guide rods 22 to effectively guide the elastic elements 23 to contract, avoiding possible skewing or instability when the elastic elements 23 are under force, thereby ensuring the reliability of the pin module.

[0052] In some embodiments of this utility model, the first end of the guide rod 22 passes through the other, and the first end of the guide rod 22 is threadedly connected to an adjusting nut 24, which is used to adjust the compression of the elastic element 23.

[0053] Specifically, such as Figure 1 and Figure 2 As shown, the base 20 is provided with a connecting hole that extends through in the first direction. The number and position of the connecting holes correspond to the number of guide rods 22. The first end of the guide rod 22 passes through the connecting hole, and the first end of the guide rod 22 is threadedly connected to an adjusting nut 24. By rotating the adjusting nut 24, the position of the adjusting nut 24 in the first direction can be adjusted, thereby changing the maximum distance between the base 20 and the floating seat 21. This can change the compression amount of the elastic element 23, and the pin insertion force range can be flexibly adjusted by rotating the adjusting nut 24, which can effectively improve the applicability of the pin insertion module.

[0054] In some optional embodiments of this utility model, a linear bearing 26 is fixedly connected to the side of the base 20 away from the floating seat 21 at a position corresponding to the connecting hole. The first end of the guide rod 22 passes through the linear bearing 26 and is threadedly connected to the adjusting nut 24. When the pin module is not inserted, the adjusting nut 24 abuts against the linear bearing 26. It should be noted that when the linear bearing 26 is not provided, the adjusting nut 24 abuts against the base 20 when the pin module is not inserted; this will not be described again in this example.

[0055] According to one embodiment of the present invention, the nail suction assembly 10 is fixedly connected to the floating seat 21.

[0056] In this embodiment, the fixed connection ensures that the pin-suction assembly 10 and the floating seat 21 always maintain a precise relative position, which can guarantee the yield of the pins.

[0057] In some alternative embodiments of this invention, the position of the nail suction assembly 10 relative to the limiting member 30 is adjustable in the first direction.

[0058] In other words, the position of the nail-attracting assembly 10 relative to the limiting member 30 in the first direction is adjustable. For example, the position of the nail-attracting assembly 10 on the floating seat 21 along the first direction is adjustable, or the position of the nail-attracting assembly 10 on the floating seat 21 along the first direction is adjustable, so that the nail insertion module can be switched between the first state and the second state.

[0059] The first state can be the nail-collecting state. In this state, the nail-collecting nozzle 12 of the nail-collecting assembly 10 protrudes from the limiting member 30. When collecting the sealing nail, the limiting member 30 can avoid the sealing nail, which is beneficial for the nail-collecting assembly 10 to collect the sealing nail in areas where the sealing nails are densely arranged.

[0060] The second state can be the insertion state, in which the suction nozzle 12 of the suction assembly 10 is flush with or retracted within the limiting member 30. In this case, the sealing nail can be inserted into the injection hole to a predetermined depth by the limiting member 30 fitting against the top of the battery.

[0061] Furthermore, in this example, by adjusting the relative positions of the pin-attracting assembly 10 and the limiting member 30 in the first direction, the pin-insertion module can be adapted to different types of batteries and sealing pins, which can effectively improve the applicability of the pin-insertion module.

[0062] In some embodiments of this utility model, the nail suction assembly 10 is movable along the first direction, and the nail insertion module further includes: a driving member 40, which is disposed on the floating seat 21 and connected to the nail suction assembly 10. The driving member 40 is used to drive the nail suction assembly 10 to move along the first direction.

[0063] Specifically, such as Figure 1 As shown, the floating seat 21 is fixedly connected to a driving component 40, which can be a cylinder. The output end of the driving component 40 is movable along the first direction. The nail-attracting assembly 10 is connected to the output end of the driving component 40. The output end of the driving component 40 can switch between the nail-attracting position and the nail-insertion position. The driving component 40 can drive the nail-attracting assembly 10 to move along the first direction, thereby enabling the nail-insertion module to switch between a first state (i.e., the output end of the driving component 40 is in the nail-attracting position) and a second state (i.e., the output end of the driving component 40 is in the nail-insertion position). Moreover, by adjusting the position of the nail-attracting assembly 10 in the first direction, the nail-insertion module can be adapted to different types of batteries and sealing nails. The structure is simple and easy to produce and assemble.

[0064] like Figure 1 As shown, in some optional examples of this utility model, a magnetic switch 41 is provided on one side of the driving member 40, and the magnetic switch 41 can detect the nail suction position and the nail insertion position of the driving member 40.

[0065] According to one embodiment of the present invention, the limiting member 30 is configured as a guide sleeve, the limiting member 30 is fixedly connected to the floating seat 21, and the limiting member 30 is sleeved on the nail suction assembly 10.

[0066] In other words, such as Figure 1 As shown, the limiting member 30 is configured as a sleeve structure extending along a first direction, so that it can be used as a guide sleeve. In this embodiment, the limiting member 30 is fixedly connected to the floating seat 21, and the limiting member 30 is sleeved on the nail-attracting assembly 10, so that the limiting member 30 can guide the nail-attracting assembly 10, thereby ensuring the stability of the movement of the nail-attracting assembly 10 and improving the yield of nail insertion.

[0067] In some embodiments of this utility model, the pin insertion module further includes a floating connector 50, which includes a first connecting part 51 and a second connecting part 52 that are relatively movable along a second direction. The first connecting part 51 is connected to the driving member 40, and the second connecting part 52 is connected to the pin suction assembly 10.

[0068] In other words, such as Figure 1As shown, the driving member 40 and the nail suction assembly 10 can be connected together via a floating joint 50. Specifically, the floating joint 50 includes a first connecting portion 51 and a second connecting portion 52, wherein the first connecting portion 51 is fixedly connected to the driving member 40, the first connecting portion 51 is movably disposed on the second connecting portion 52 along a second direction, the second direction being perpendicular to the first direction (for example, it can be the radial direction of the limiting member 30), and the second connecting portion 52 is fixedly connected to the nail suction seat 11 of the nail suction assembly 10.

[0069] In this embodiment, the floating joint 50 can compensate to a certain extent for minor displacements caused by installation errors or during operation, ensuring that the nail suction assembly 10 remains stable during operation.

[0070] According to one embodiment of the present invention, the floating seat 21 includes: a first mounting plate 211, a driving member 40 disposed on the side of the first mounting plate 211 near the base 20; a second mounting plate 212, in a first direction, the second mounting plate 212 is located on the side of the first mounting plate 211 away from the base 20, the first mounting plate 211 and the second mounting plate 212 are connected by a connector 213, a limiting member 30 is disposed on the side of the second mounting plate 212 away from the first mounting plate 211, a portion of the nail suction assembly 10 is located between the first mounting plate 211 and the second mounting plate 212, and the nail suction nozzle 12 of the nail suction assembly 10 passes through the second mounting plate 212 and is located on the side of the second mounting plate 212 away from the first mounting plate 211.

[0071] Specifically, such as Figure 1 As shown, the floating seat 21 mainly includes a first mounting plate 211 and a second mounting plate 212. The first mounting plate 211 and the second mounting plate 212 are spaced apart along a first direction. Two connecting members 213 are provided between the first mounting plate 211 and the second mounting plate 212. The connecting members 213 are configured as connecting posts extending along the first direction. The first end of the connecting member 213 is fixedly connected to the first mounting plate 211, and the second end of the connecting member 213 is fixedly connected to the second mounting plate 212. The first mounting plate 211 is located on the side of the second mounting plate 212 near the base 20, and the first mounting plate 211 is fixedly connected to the guide rod 22. The driving member 40 is fixedly connected to the side of the first mounting plate 211 near the base 20, thereby making full use of the space between the first mounting plate 211 and the base 20.

[0072] like Figure 1As shown, the nail suction seat 11 of the nail suction assembly 10 is located between the first mounting plate 211 and the second mounting plate 212, thereby making full use of the space between the first mounting plate 211 and the second mounting plate 212. The first mounting plate 211 has a through hole suitable for the output end of the drive member 40 to pass through, and the output end of the drive member 40 passes through the through hole and is connected to the nail suction assembly 10. The nail suction nozzle 12 of the nail suction assembly 10 passes through the second mounting plate 212 and is located on the side of the second mounting plate 212 opposite to the first mounting plate 211, so that the nail suction nozzle 12 can pick up the sealing nail and insert the sealing nail into the electrolyte filling hole of the battery. The limiting member 30 is fixedly connected to the side of the second mounting plate 212 opposite to the first mounting plate 211, so that the sealing nail can be inserted into the electrolyte filling hole to a predetermined depth by fitting the limiting member 30 against the top of the battery.

[0073] In some embodiments of this utility model, the pin insertion module further includes a stop 60, which is disposed on the pin suction assembly 10. The position of the stop 60 in the first direction is adjustable. The stop 60 is used to cooperate with the first mounting plate 211 to limit the position of the pin suction assembly 10.

[0074] In other words, such as Figure 1 As shown, the nail-collecting assembly 10 has a stop 60 on the side near the first mounting plate 211 of the nail-collecting seat 11. The number of stop 60s can be one or two. By cooperating with the first mounting plate 211, the upward movement distance of the nail-collecting assembly 10 in the first direction can be limited. When the stop 60 abuts against the first mounting plate 211, the nail-collecting assembly 10 is confined to a predetermined position, preventing excessive upward movement. During nail insertion, by driving the nail-collecting assembly 10 to abut against the first mounting plate 211, it is ensured that the nail insertion module inserts the sealing nail to a predetermined depth, effectively preventing the sealing nail from being inserted too deeply or too insufficiently.

[0075] Furthermore, the position of the stop 60 in the first direction is adjustable, so that the stop 60 can be adjusted to the corresponding position according to the model of the battery and the sealing nail, which can effectively improve the reliability and applicability of the nail module.

[0076] It should be noted that when adjusting the position of the stop 60, the position of the stop 60 can be adjusted according to the predetermined height of the top of the sealing nail and the top of the battery after the nail is inserted, so that the distance between the head of the nail suction nozzle 12 (i.e., the end face that contacts the sealing nail) and the head of the limiting member 30 (i.e., the end face that contacts the battery) is equal to the height difference between the top of the sealing nail and the top of the battery. This embodiment will not be described in detail.

[0077] According to one embodiment of the present invention, the stop 60 is configured as a screw, which is threadedly connected to the pin-attracting assembly 10.

[0078] In this embodiment, the stop 60 is a screw. The position of the stop 60 in the first direction can be adjusted by rotating the stop 60. The structure is simple and easy to operate.

[0079] In summary, the pin insertion module provided in this embodiment, by setting a limiting member 30 and a pin suction assembly 10 on the elastically floating seat 21, enables the pin insertion module to insert the sealing pin to a predetermined depth when inserting batteries of different heights. This effectively avoids the problem of the sealing pin being inserted too deeply or too insufficiently due to the size error of the battery, significantly improves the yield of pin insertion, and thus improves production efficiency and product quality.

[0080] like Figures 3 to 5 As shown, an embodiment of the present invention also provides a pin insertion device 100, including the pin insertion module described in any of the above embodiments. Since the pin insertion module according to the embodiments of the present invention has the above-mentioned technical effects, the pin insertion device 100 according to the embodiments of the present invention also has corresponding technical effects, which will not be repeated in this embodiment.

[0081] like Figures 3 to 5 As shown, according to one embodiment of the present invention, the nail insertion device 100 further includes a multi-axis robot device 70 (e.g., a four-axis robot device), a flexible vibratory feeder device 71, an ion wind device 72, a first CCD device 73, and a second CCD device 74. The multi-axis robot device 70 is equipped with a nail insertion drive unit 75, the output end of which is fixedly connected to the base 20. The multi-axis robot device 70 can drive the nail insertion module to move between the nail insertion station and the loading station, and the nail insertion drive unit 75 can control the movement of the nail insertion module in a first direction, enabling the nail suction assembly 10 to suction and insert nails.

[0082] like Figures 3 to 5 As shown, the nail suction nozzle 12 of the nail suction assembly 10 is connected to the negative pressure generating device via an air connector 13 and an air valve assembly. A pressure gauge is connected to the air connector 13. The air valve assembly includes a vacuum valve. After the vacuum valve is opened, the nail suction nozzle 12 begins to suction the nail. By reading the pressure gauge value, it can be determined whether the nail suction nozzle 12 has successfully suctioned the sealing nail.

[0083] like Figures 3 to 5As shown, the flexible vibratory feeder 71 is installed at the feeding station. The flexible vibratory feeder 71 is used to hold the sealing nails. Specifically, the disc of the flexible vibratory feeder 71 has holes suitable for accommodating the sealing nails. The flexible vibratory feeder 71 vibrates the sealing nails into the holes, allowing the lower end of the sealing nail to be inserted into the hole. The ion air device 72 faces the disc of the flexible vibratory feeder 71. The ion air device 72 blows an ionized airflow into the flexible vibratory feeder 71, which neutralizes static electricity and reduces electrostatic adsorption, thereby ensuring that the sealing nails remain clean during the feeding process and avoiding dust adhesion or material sticking caused by static electricity. Furthermore, blowing the sealing nails facilitates their transfer into the holes of the disc of the flexible vibratory feeder 71.

[0084] The first CCD device 73 can be located above the flexible vibratory feeder device 71. The first CCD device 73 can acquire the position information of the sealing pins on the flexible vibratory feeder device 71 and transmit the acquired position information to the multi-axis robot device 70. The second CCD device 74 can be located above the pin insertion station. The second CCD device 74 can acquire the position information of the battery's electrolyte filling hole and transmit the acquired position information to the multi-axis robot device 70.

[0085] When the nail insertion device 100 according to the present invention is in use, the multi-axis robot device 70 can drive the nail insertion module to move to the corresponding position to perform nail suction operation according to the position information of the sealing nail provided by the first CCD device 73. After the nail suction is completed, the multi-axis robot device 70 can drive the nail insertion module to move directly above the injection hole according to the position information of the injection hole provided by the second CCD device 74. Then, the output end of the nail insertion drive unit 75 is controlled to descend to the position corresponding to the lowest battery. If the battery is higher than the lowest battery, the limiting member 30 abuts against the top of the battery, and the nail suction assembly 10 moves upward relative to the output end of the nail insertion drive unit 75, thereby avoiding insufficient or excessive insertion depth of the sealing nail.

[0086] The embodiments of this utility model also provide a pinning method, in which the pinning device 100 of any of the above embodiments is used to pin the battery, and the pinning method includes: S100 to S400.

[0087] S100: Transport the battery to the insertion station;

[0088] Specifically, during battery insertion, a conveying device can be used to transport the battery to the designated insertion station.

[0089] S200, Use the nail suction assembly 10 to pick up the sealing nail;

[0090] In detail, the multi-axis robot device 70 can drive the pin insertion module to move to the corresponding position on the loading station to pick up the sealing pin based on the position information of the sealing pin provided by the first CCD device 73.

[0091] S300, Move the pin insertion module to the pin insertion station;

[0092] Specifically, after the nail suction is completed, the multi-axis robot device 70 can drive the nail insertion module to move directly above the injection hole (i.e., the nail insertion station) according to the position information of the injection hole provided by the second CCD device 74.

[0093] S400, the base 20 is driven to move in the first direction based on the height of the lowest battery so that the limiting member 30 fits against the battery. Through the movement of the base 20, the sealing pin is inserted into the battery's injection hole to a predetermined depth.

[0094] In other words, in the pin insertion device 100, the output of the pin insertion drive unit 75 is set based on the height of the lowest battery, and uses this as a reference to drive the base 20 to move in the first direction, so that the limiting member 30 can not only fit with the top of the highest battery, but also fit with the top of the lowest battery. During the pin insertion process, if the battery is higher than the lowest battery, the limiting member 30 abuts against the top of the battery, and the pin suction assembly 10 moves upward relative to the output end of the pin insertion drive unit 75. If the lowest battery is being pinned, when the sealing pin is inserted to a predetermined depth, the limiting member 30 fits exactly with the top of the battery, or the limiting member 30 abuts against the top of the battery.

[0095] Therefore, according to the pin insertion method provided in this embodiment, when inserting batteries of different heights, the sealing pin can be inserted to a predetermined depth, effectively avoiding the problem of the sealing pin being inserted too deeply or too insufficiently due to the size error of the battery, significantly improving the yield of pin insertion, and thus improving production efficiency and product quality.

[0096] It should be noted that dimensional errors during battery manufacturing cause battery height to fluctuate within a certain range. The lowest battery refers to the smallest battery in that batch, while the highest battery refers to the largest battery.

[0097] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.
