[0033] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0034] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0035] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0036] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0037] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0038] The pin insertion module according to the embodiment of the present invention is first described in detail below with reference to the accompanying drawings.

[0039] like Figure 1 and Figure 2 As shown, the nail inserting module according to the embodiment of the present invention includes: a nail suction component 10, a base 20 and a limiting member 30.

[0040] Specifically, the nail suction assembly 10 is used to absorb the sealing nail. A floating seat 21 that can elastically float along a first direction is provided on one side of the base 20. The nail suction assembly 10 is arranged on the floating seat 21. The base 20 can move along the first direction so that the nail suction assembly 10 can insert the sealing nail into the injection hole of the battery. The limiter 30 is arranged on the floating seat 21. The limiter 30 is used to fit with the battery when the sealing nail is inserted into the injection hole to a predetermined depth to limit the insertion depth of the sealing nail.

[0041] In other words, if Figure 1 and Figure 2As shown, the nail insertion module according to the embodiment of the present invention is mainly applied to the nail insertion device 100, and the nail insertion module mainly includes a nail suction assembly 10 and a base 20. Among them, the nail suction assembly 10 includes a nail suction seat 11 and a nail suction nozzle 12, and the first end (for example, the upper end) of the nail suction nozzle 12 is fixedly connected to the nail suction seat 11, and the nail suction nozzle 12 is used to connect with the negative pressure generating device. By controlling the operation of the negative pressure generating device, the second end (for example, the lower end) of the nail suction nozzle 12 can controllably absorb the sealing nail.

[0042] Specifically, Figure 5 As shown, the base 20 is used to connect with the nail driving unit 75 (for example, a cylinder), and the nail driving unit 75 can drive the base 20 to move along a first direction. The first direction is the same as the length direction of the sealing nail on the nail suction assembly 10 (that is, the depth direction of the injection hole). When the length direction of the sealing nail on the nail suction assembly 10 is the vertical direction, the first direction is the vertical direction. Figure 1 As shown, a floating seat 21 that can float elastically in a first direction is provided on one side of the base 20, and the nail suction assembly 10 is installed on the floating seat 21. When inserting a nail, the nail insertion driving unit 75 drives the base 20 to move in the first direction, so that the nail suction assembly 10 moves in the first direction, so that the sealing nail sucked by the nail suction nozzle 12 can be inserted into the liquid injection hole of the battery.

[0043] Furthermore, if Figure 1 and Figure 2 As shown, a side of the floating seat 21 near the second end of the nail suction nozzle 12 is fixedly connected to a limiting member 30. When the sealing nail is not inserted into the injection hole, the limiting member 30 is spaced apart from the top of the battery; and when the sealing nail is inserted into the injection hole to a predetermined depth, the limiting member 30 fits against the top of the battery.

[0044] During the nail insertion process, the nail insertion driving unit 75 drives the base 20 to move toward the battery. When the stopper 30 is in contact with the top of the battery, the depth of the sealing nail inserted into the injection hole is the predetermined depth. If the base 20 continues to move toward the battery, the stopper 30 will limit the floating seat 21 from continuing to move toward the battery. Since the floating seat 21 can float elastically, during the movement of the base 20, the distance between the base 20 and the floating seat 21 will become smaller, while the nail suction assembly 10 on the floating seat 21 remains stationary relative to the battery.

[0045] Therefore, when the stopper 30 is in contact with the top of the battery, the suction nail assembly 10 can be prevented from continuing to move toward the battery, thereby ensuring that the depth of the sealing nail inserted into the injection hole remains at a predetermined depth and will not be further inserted.

[0046] That is to say, during the nail insertion process, the nail insertion module according to the embodiment of the present invention only needs to be controlled based on the height dimension of the lowest battery to ensure that the limiter 30 always fits with the top of the battery, thereby effectively avoiding insufficient or excessive insertion depth of the sealing nail, thereby effectively improving the nail insertion yield.

[0047] Therefore, according to the nail insertion module provided in this embodiment, by arranging the limiter 30 and the nail suction assembly 10 on the elastically floating floating seat 21, the nail insertion module can insert the sealing nail to a predetermined depth when inserting nails into batteries of different heights, effectively avoiding the problem of the sealing nail being inserted too deeply or insufficiently due to the size error of the battery, significantly improving the yield rate of the nail insertion, and thus improving the production efficiency and product quality.

[0048] According to one embodiment of the present invention, the nail module also includes: at least one guide rod 22, the guide rod 22 is fixedly connected to one of the base 20 and the floating seat 21, and the guide rod 22 is movably disposed on the other of the base 20 and the floating seat 21 along a first direction; an elastic member 23, the elastic member 23 is disposed between the base 20 and the floating seat 21, and the elastic member 23 is sleeved on the guide rod 22.

[0049] Specifically, Figure 1 and Figure 2 As shown, the base 20 has a first side and a second side that are arranged opposite to each other in the first direction, a flange seat 25 for connecting to the output end of the nail driving unit 75 is fixedly connected to the first side of the base 20, and the floating seat 21 is located on the second side of the base 20 and is spaced apart from the base 20. The base 20 and the floating seat 21 are movably connected together through one or more guide rods 22, so that the floating seat 21 can move along the first direction relative to the base 20. In this embodiment, the base 20 and the floating seat 21 are movably connected together through two guide rods 22, so as to ensure the stability of the structure.

[0050] Specifically, the connection methods between the base 20 and the floating seat 21 include but are not limited to the following:

[0051] 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 mounted on the base 20 along the first direction;

[0052] Case 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.

[0053] In this embodiment, an elastic member 23 is provided between the base 20 and the floating seat 21. The elastic member 23 may be a spring, one end of which abuts against or is fixedly connected to the floating seat 21, and the other end of which abuts against or is fixedly connected to the base 20, so that the floating seat 21 can be elastically floated along the first direction, and the structure is simple. The number of the elastic members 23 may be the same as the number of the guide rods 22, and the elastic members 23 may be sleeved on the corresponding guide rods 22, so that the guide rods 22 can effectively guide the elastic members 23 to contract, avoiding the deflection or instability that may occur when the elastic members 23 are subjected to force, thereby ensuring the reliability of the pin insertion module.

[0054] In some embodiments of the present invention, the first end of the guide rod 22 passes through the other, and the first end of the guide rod 22 is threadedly connected with an adjusting nut 24 , and the adjusting nut 24 is used to adjust the compression amount of the elastic member 23 .

[0055] Specifically, Figure 1 and Figure 2 As shown, the base 20 is provided with connecting holes penetrating along the first direction, the connecting holes correspond to the number and position of the guide rod 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 with an adjusting nut 24, and the position of the adjusting nut 24 in the first direction can be adjusted by rotating the adjusting nut 24, so that the maximum spacing between the base 20 and the floating seat 21 changes, thereby changing the compression amount of the elastic member 23, so that the range of the nail insertion force can be flexibly adjusted by rotating the adjusting nut 24, which can effectively improve the applicability of the nail insertion module.

[0056] In some optional examples of the present invention, 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 connection hole, and the first end of the guide rod 22 passes through the linear bearing 26 and is threadedly connected to the adjustment nut 24. When the nail insertion module is not inserted, the adjustment nut 24 abuts against the linear bearing 26. It should be noted that when the linear bearing 26 is not provided, when the nail insertion module is not inserted, the adjustment nut 24 abuts against the base 20, and this example will not be repeated.

[0057] According to one embodiment of the present invention, the nail suction assembly 10 is fixedly connected to the floating seat 21 .

[0058] In this embodiment, the fixed connection method allows the nail suction assembly 10 and the floating seat 21 to always maintain an accurate relative position relationship, thereby ensuring the nail insertion yield.

[0059] In some optional examples of the present invention, in the first direction, the position of the nail suction assembly 10 relative to the limiting member 30 is adjustable.

[0060] That is to say, the position of the nail suction component 10 relative to the limiting member 30 in the first direction is adjustable, for example, the position of the nail suction component 10 on the floating seat 21 along the first direction is adjustable, or the position of the nail suction component 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.

[0061] The first state may be a nail sucking state, in which the nail sucking nozzle 12 of the nail sucking assembly 10 protrudes from the limiting member 30. When sucking sealing nails, the limiting member 30 may avoid the sealing nails, which is beneficial for the nail sucking assembly 10 to suck sealing nails in areas where the sealing nails are densely arranged.

[0062] The second state may be a nail insertion state, in which the nail suction nozzle 12 of the nail suction assembly 10 is flush with the stopper 30 or retracted in the stopper 30. In this case, the sealing nail can be inserted into the injection hole to a predetermined depth by the stopper 30 being fitted with the top of the battery.

[0063] In addition, in this example, by adjusting the relative position of the nail suction assembly 10 and the limiting member 30 in the first direction, the nail insertion module can be adapted to batteries and sealing nails of different models, which can effectively improve the applicability of the nail insertion module.

[0064] In some embodiments of the present invention, 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, connected to the nail suction assembly 10, and used to drive the nail suction assembly 10 to move along the first direction.

[0065] Specifically, Figure 1 As shown, the floating seat 21 is fixedly connected with a driving member 40, and the driving member 40 can be a cylinder. The output end of the driving member 40 is movable along the first direction, and the nail suction component 10 is connected to the output end of the driving member 40. The output end of the driving member 40 is switchable between the nail suction position and the nail insertion position. The driving member 40 can drive the nail suction component 10 to move along the first direction, so that the nail insertion module can be switched between the first state (that is, the output end of the driving member 40 is in the nail suction position) and the second state (that is, the output end of the driving member 40 is in the nail insertion position). Moreover, by adjusting the position of the nail suction component 10 in the first direction, the nail insertion module can be suitable for different models of batteries and sealing nails, and the structure is simple and convenient for production and assembly.

[0066] like Figure 1 As shown, in some optional examples of the present invention, a magnetic switch 41 is provided on one side of the driving member 40, and the nail suction position and the nail insertion position of the driving member 40 can be detected by the magnetic switch 41.

[0067] 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 .

[0068] That is to say, Figure 1 As shown, the stopper 30 is configured as a sleeve structure extending along the first direction, so that it can be used as a guide sleeve. In this embodiment, the stopper 30 is fixedly connected to the floating seat 21, and the stopper 30 is sleeved on the nail suction assembly 10, so that the stopper 30 can guide the nail suction assembly 10, thereby ensuring the stability of the activity of the nail suction assembly 10, and further improving the nail insertion yield.

[0069] In some embodiments of the present invention, the nail insertion module also includes: a floating joint 50, the floating joint 50 includes a first connecting part 51 and a second connecting part 52 that can move relatively along the second direction, the first connecting part 51 is connected to the driving member 40, and the second connecting part 52 is connected to the nail suction assembly 10.

[0070] In other words, if Figure 1 As shown, the driving member 40 and the nail suction assembly 10 can be connected together through a floating joint 50. Specifically, the floating joint 50 includes a first connection portion 51 and a second connection portion 52, wherein the first connection portion 51 is fixedly connected to the driving member 40, the first connection portion 51 is movably disposed on the second connection portion 52 along a second direction, the second direction is perpendicular to the first direction (for example, it can be the radial direction of the limiter 30), and the second connection portion 52 is fixedly connected to the nail suction seat 11 of the nail suction assembly 10.

[0071] In this embodiment, the floating joint 50 can compensate for minor displacements due to installation errors or during operation to a certain extent, thereby ensuring that the nail suction assembly 10 remains stable during operation.

[0072] According to one embodiment of the present invention, the floating seat 21 includes: a first mounting plate 211, a driving member 40 is arranged on a side of the first mounting plate 211 close to the base 20; a second mounting plate 212, in the 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 connecting member 213, the limiting member 30 is arranged on the side of the second mounting plate 212 away from the first mounting plate 211, part 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.

[0073] Specifically, Figure 1As shown, the floating seat 21 mainly includes a first mounting plate 211 and a second mounting plate 212, wherein the first mounting plate 211 and the second mounting plate 212 are spaced apart along a first direction, two connecting members 213 are arranged between the first mounting plate 211 and the second mounting plate 212, and the connecting members 213 are configured as connecting columns extending along the first direction, and 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 a side of the second mounting plate 212 close to 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 a side of the first mounting plate 211 close to the base 20, so that the space between the first mounting plate 211 and the base 20 can be fully utilized.

[0074] like Figure 1 As 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, so that the space between the first mounting plate 211 and the second mounting plate 212 can be fully utilized. The first mounting plate 211 is provided with a through hole suitable for the output end of the driving member 40 to pass through, and the output end of the driving member 40 passes through the through hole to be connected with 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 away from the first mounting plate 211, so that the nail suction nozzle 12 can suck the sealing nail and can insert the sealing nail into the injection hole of the battery. The limiting member 30 is fixedly connected to the side of the second mounting plate 212 away from the first mounting plate 211, so that the sealing nail can be inserted into the injection hole to a predetermined depth by fitting the limiting member 30 with the top of the battery.

[0075] In some embodiments of the present invention, the nail insertion module further includes: a stopper 60, which is disposed on the nail suction assembly 10, and the position of the stopper 60 in the first direction is adjustable. The stopper 60 is used to cooperate with the first mounting plate 211 to limit the position of the nail suction assembly 10.

[0076] That is to say, Figure 1 As shown, the nail suction seat 11 of the nail suction assembly 10 is provided with a stopper 60 on one side close to the first mounting plate 211. The number of the stopper 60 can be one or two, etc., and the stopper 60 cooperates with the first mounting plate 211 to limit the upward movement distance of the nail suction assembly 10 in the first direction. When the stopper 60 is in abutment with the first mounting plate 211, the nail suction assembly 10 is limited to a predetermined position, which can prevent the nail suction assembly 10 from moving upward excessively. When inserting the nail, by driving the nail suction assembly 10 to make the stopper 60 abut against the first mounting plate 211, it can be ensured that the nail insertion module inserts the sealing nail to a predetermined depth, which can effectively avoid the problem of the sealing nail being inserted too deep or insufficiently.

[0077] Furthermore, the position of the stopper 60 in the first direction is adjustable, so that the stopper 60 can be adjusted to a corresponding position according to the models of the battery and the sealing nail, which can effectively improve the reliability and applicability of the nail module.

[0078] It should be noted that when adjusting the position of the stopper 60, the position of the stopper 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 in contact with the sealing nail) and the head of the limiter 30 (i.e., the end face in contact with the battery) is equal to the height difference between the top of the sealing nail and the top of the battery, which will not be repeated in this embodiment.

[0079] According to one embodiment of the present invention, the stopper 60 is configured as a screw, and the screw is threadedly connected to the nail suction assembly 10 .

[0080] In this embodiment, the stopper 60 is a screw, and the position of the stopper 60 in the first direction can be adjusted by rotating the stopper 60 . The structure is simple and the operation is convenient.

[0081] In summary, according to the nail insertion module provided in this embodiment, by arranging the limiter 30 and the nail suction assembly 10 on the elastically floating floating seat 21, the nail insertion module can insert the sealing nail to a predetermined depth when inserting nails into batteries of different heights, effectively avoiding the problem of the sealing nail being inserted too deeply or insufficiently due to the size error of the battery, significantly improving the yield of the nail insertion, and thus improving the production efficiency and product quality.

[0082] like Figures 3 to 5 As shown, an embodiment of the present invention further provides a nail insertion device 100, including the nail insertion module described in any of the above embodiments. Since the nail insertion module according to the embodiment of the present invention has the above technical effects, the nail insertion device 100 according to the embodiment of the present invention also has the corresponding technical effects, which will not be described in detail in this embodiment.

[0083] 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 (for example, a four-axis robot device), a flexible vibration disk 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 provided with a nail insertion drive unit 75, and the output end of the nail insertion drive unit 75 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 nail insertion module to move in the first direction, so that the nail suction assembly 10 can suck and insert nails.

[0084] like Figures 3 to 5As shown, the nail sucking nozzle 12 of the nail sucking assembly 10 is connected to the negative pressure generating device through the air joint 13 and the air valve assembly, and a pressure gauge is connected to the air joint 13. The air valve assembly includes a vacuum valve. After the vacuum valve is opened, the nail sucking nozzle 12 starts to suck nails. By reading the value of the pressure gauge, it can be determined whether the nail sucking nozzle 12 successfully sucks the sealing nails.

[0085] like Figures 3 to 5 As shown, the flexible vibration disk device 71 is arranged at the loading station, and the flexible vibration disk device 71 is used to hold the sealing nail. Specifically, the disk body of the flexible vibration disk device 71 is provided with a hole body suitable for accommodating the sealing nail. The sealing nail can be vibrated into the hole body through the flexible vibration disk device 71, so that the lower end of the sealing nail is inserted into the hole body. The ion wind device 72 faces the disk body of the flexible vibration disk device 71. The ion wind device 72 can blow ion airflow to the flexible vibration disk device 71, which can neutralize static electricity and reduce static electricity adsorption, thereby ensuring that the sealing nail remains clean during the feeding process, avoiding dust adhesion or material adhesion caused by static electricity, and by blowing the sealing nail, it is helpful to move the sealing nail into the hole body of the disk body of the flexible vibration disk device 71.

[0086] The first CCD device 73 may be located above the flexible vibration disk device 71, and the position information of the sealing nail on the flexible vibration disk device 71 may be obtained through the first CCD device 73, and the obtained position information may be transmitted to the multi-axis robot device 70. The second CCD device 74 may be located above the nail insertion station, and the position information of the battery injection hole may be obtained through the second CCD device 74, and the obtained position information may be transmitted to the multi-axis robot device 70.

[0087] When the nail insertion device 100 according to the embodiment of 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 the 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 to just above the injection hole according to the position information of the injection hole provided by the second CCD device 74, and then control the output end of the nail insertion drive unit 75 to drop to the position corresponding to the lowest battery. If the battery is higher than the lowest battery, the limit 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.

[0088] An embodiment of the present invention further provides a nail insertion method, which uses the nail insertion device 100 of any of the above embodiments to insert a nail into a battery. The nail insertion method includes: S100 to S400.

[0089] S100, transporting the battery to the nail insertion station;

[0090] Specifically, when the battery is inserted into the nail, the battery can be transported to a predetermined nail insertion station by using a transport device.

[0091] S200, using the nail suction assembly 10 to suck the sealing nail;

[0092] In detail, the multi-axis robot device 70 can drive the nail insertion module to move to the corresponding position on the loading station to absorb the sealing nail according to the position information of the sealing nail provided by the first CCD device 73.

[0093] S300, moving the nail insertion module to the nail insertion station;

[0094] Specifically, after the nail suction is completed, the multi-axis robot device 70 can drive the nail insertion module to move to the top of the liquid injection hole (ie, the nail insertion station) according to the position information of the liquid injection hole provided by the second CCD device 74 .

[0095] S400, driving the base 20 to move along the first direction based on the height of the lowest battery, so that the limiting member 30 fits with the battery, and inserting the sealing nail into the battery's injection hole to a predetermined depth through the movement of the base 20.

[0096] That is to say, in the nail insertion device 100, the output of the nail insertion driving unit 75 is set based on the height of the lowest battery, and this is used as a reference to drive the base 20 to move along the first direction, so that the limiter 30 can not only fit with the top of the highest battery, but also fit with the top of the lowest battery. During the nail insertion process, if the battery is higher than the lowest battery, the limiter 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 driving unit 75. If the lowest battery is nailed, when the sealing nail is inserted into a predetermined depth, the limiter 30 just fits against the top of the battery, or the limiter 30 abuts against the top of the battery.

[0097] Therefore, according to the nail insertion method provided in this embodiment, when nailing batteries of different heights, the sealing nail can be inserted to a predetermined depth, effectively avoiding the problem of the sealing nail being inserted too deeply or insufficiently due to the size error of the battery, significantly improving the yield of the nail insertion, and thus improving the production efficiency and product quality.

[0098] It should be noted that the dimensional errors in the battery manufacturing process cause the battery height to fluctuate within a certain range. The lowest battery refers to the battery with the smallest height in the batch of batteries, while the highest battery refers to the battery with the largest height.

[0099] The above embodiments focus on 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. Considering the simplicity of the text, they will not be repeated here.

It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
