It should be noted that the relative arrangement of the components and steps set forth in the examples, as well as the numerical expressions and values, are not limitations on the scope of the present application unless otherwise specifically stated.

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

[0035] Techniques, methods, and apparatus known to those of ordinary skill in the relevant art can not be discussed in detail herein, but should be considered as if the techniques, methods, and apparatus were discussed in detail herein, where appropriate.

[0036] In all of the examples shown and discussed herein, any specific values should be interpreted as merely exemplary, and not as a limitation on the scope of the exemplary embodiments.

[0037] It should be noted that like references and characters herein refer to like items throughout the attached drawings and figures, and that discussion of one item in a figure should not be interpreted as a requirement of further discussion of that item in subsequent figures.

[0038] The pin insertion module according to the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0039] As shown in Figure 1 and Figure 2 , the pin insertion module according to the embodiments of the present application includes a pin suction assembly 10, a base 20, and a limiting member 30.

[0040] Specifically, the pin suction assembly 10 is configured to suction a sealing pin, the base 20 is provided with a floating seat 21 that is elastically floatable in a first direction, the pin suction assembly 10 is disposed on the floating seat 21, the base 20 is movable in the first direction so that the pin suction assembly 10 can insert the sealing pin into a liquid injection hole of a battery, and the limiting member 30 is disposed on the floating seat 21 and configured to abut against the battery when the sealing pin is inserted into the liquid injection hole to a predetermined depth, so as to limit the insertion depth of the sealing pin.

[0041] In other words, as shown in Figure 1 and Figure 2As shown, the nail inserting module according to the embodiment of the present application is mainly applied to the nail inserting device 100, and mainly comprises a nail suction assembly 10 and a base 20. The nail suction assembly 10 comprises a nail suction seat 11 and a nail suction nozzle 12, the first end (for example, the upper end) of the nail suction nozzle 12 is fixedly connected with the nail suction seat 11, and the nail suction nozzle 12 is used to be connected with a 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 be controlled to suck the sealing nail.

[0042] Specifically, as shown in Figure 5 The base 20 is used to be connected with a nail inserting driving unit 75 (for example, a pneumatic cylinder), and the nail inserting driving unit 75 can drive the base 20 to move along a first direction, and 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 liquid injection hole). When the length direction of the sealing nail on the nail suction assembly 10 is a vertical direction, the first direction is also the vertical direction. As shown in Figure 1 One side of the base 20 is provided with a floating seat 21 which can elastically float along the first direction, and the nail suction assembly 10 is installed on the floating seat 21. During the nail inserting process, the nail inserting driving 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 liquid injection hole of the battery.

[0043] Further, as shown in Figure 1 and Figure 2 The floating seat 21 is fixedly connected with a limiting piece 30 on the side close to the second end of the nail suction nozzle 12. When the sealing nail is not inserted into the liquid injection hole, the limiting piece 30 is spaced apart from the top of the battery; and when the sealing nail is inserted into the liquid injection hole to a predetermined depth, the limiting piece 30 is in close contact with the top of the battery.

[0044] During the nail inserting process, the nail inserting driving unit 75 drives the base 20 to move towards the battery. When the limiting piece 30 is in close contact with the top of the battery, the depth of the sealing nail inserted into the liquid injection hole is the predetermined depth. If the base 20 continues to move towards the battery, the limiting piece 30 will limit the floating seat 21 to continue to move towards the battery. Since the floating seat 21 can elastically float, the distance between the base 20 and the floating seat 21 becomes smaller during the movement of the base 20, and the nail suction assembly 10 on the floating seat 21 remains stationary relative to the battery.

[0045] Therefore, after the limiting piece 30 is in close contact with the top of the battery, the nail suction assembly 10 can be prevented from continuing to move towards the battery, thereby ensuring that the depth of the sealing nail inserted into the liquid injection hole remains at the predetermined depth and the sealing nail cannot be further inserted.

[0046] That is, according to the nail inserting module provided by the embodiment of the present application, only the minimum height of the battery is used as a reference to control the nail inserting process, so that the limiting piece 30 is always in contact with the top of the battery, thereby effectively avoiding the problem of insufficient or excessive insertion of the sealing nail, and effectively improving the yield of the nail insertion.

[0047] Therefore, according to the nail inserting module provided by the embodiment, the limiting piece 30 and the nail suction assembly 10 are arranged on the elastically floating floating seat 21, so that the nail inserting module can insert the sealing nail to a predetermined depth when the nail is inserted into batteries of different heights, effectively avoiding the problem of excessive or insufficient insertion of the sealing nail due to the size error of the battery, significantly improving the yield of the nail insertion, and further improving the production efficiency and product quality.

[0048] According to an embodiment of the present application, the nail inserting module further comprises at least one guide rod 22, the guide rod 22 being fixedly connected to one of the base 20 and the floating seat 21, the guide rod 22 being movably arranged in the other one of the base 20 and the floating seat 21 along the first direction; and an elastic piece 23, the elastic piece 23 being arranged between the base 20 and the floating seat 21, the elastic piece 23 being sleeved on the guide rod 22.

[0049] Specifically, as shown in Figure 1 and Figure 2 , the base 20 has a first side and a second side arranged opposite to each other in the first direction, the first side of the base 20 is fixedly connected with a flange seat 25 for connecting with the output end of the nail inserting driving unit 75, the floating seat 21 is located on the second side of the base 20 and is spaced apart from the base 20, and 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 is movable relative to the base 20 along the first direction. In the 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 mode of the base 20 and the floating seat 21 includes but is not limited to the following cases:

[0051] Case one, the guide rod 22 extends along the first direction, one end of the guide rod 22 is fixedly connected with the floating seat 21, and the guide rod 22 is movably mounted on the base 20 along the first direction;

[0052] Case two, the guide rod 22 extends along the first direction, one end of the guide rod 22 is fixedly connected with the base 20, and the guide rod 22 is movably mounted on the floating seat 21 along the first direction.

[0053] In this embodiment, the elastic member 23 is arranged between the base 20 and the floating seat 21, which can be a spring, one end of the spring is in abutment or fixed connection with the floating seat 21, and the other end of the spring is in abutment or fixed connection with the base 20, so that the floating seat 21 can be elastically floated in the first direction, and the structure is simple. The number of the elastic member 23 can be the same as that of the guide rod 22, and the elastic member 23 can be sleeved on the corresponding guide rod 22, so that the guide rod 22 can effectively guide the contraction of the elastic member 23, and the deflection or instability phenomenon of the elastic member 23 under stress can be avoided, thereby the reliability of the nail inserting module can be ensured.

[0054] In some embodiments of the present application, the first end of the guide rod 22 penetrates 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, as shown in Figure 1 and Figure 2 , the base 20 is provided with a connecting hole penetrating in the first direction, the connecting hole corresponds to the number and position of the guide rod 22, the first end of the guide rod 22 penetrates the connecting hole, and the first end of the guide rod 22 is threadedly connected with the 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 distance between the base 20 and the floating seat 21 changes, and thus the compression amount of the elastic member 23 can be changed, so that the nail inserting force range can be flexibly adjusted by rotating the adjusting nut 24, and the applicability of the nail inserting module can be effectively improved.

[0056] In some optional examples of the present application, the side of the base 20 away from the floating seat 21 is fixedly connected with a linear bearing 26 at a position corresponding to the connecting hole, the first end of the guide rod 22 penetrates the linear bearing 26 and is threadedly connected with the adjusting nut 24, and the adjusting nut 24 is in abutment with the linear bearing 26 in the case that the nail inserting module is not inserted with nails. It should be noted that when the linear bearing 26 is not arranged, the adjusting nut 24 is in abutment with the base 20 in the case that the nail inserting module is not inserted with nails, and the present example will not be described in detail.

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

[0058] In this embodiment, the fixed connection mode makes the nail suction assembly 10 and the floating seat 21 always maintain an accurate relative position relationship, and the yield of the nail insertion can be ensured.

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

[0060] That is, the position of the suction pin assembly 10 relative to the limiting member 30 in the first direction is adjustable, for example, the position of the suction pin assembly 10 on the floating seat 21 in the first direction is adjustable, or the position of the suction pin assembly 10 on the floating seat 21 in the first direction is adjustable, so that the plug-in module can be switched between the first state and the second state.

[0061] The first state can be a suction pin state, in which the suction pin nozzle 12 of the suction pin assembly 10 protrudes from the limiting member 30, and the limiting member 30 can avoid the sealing pin when sucking the sealing pin, which is beneficial for the suction pin assembly 10 to suck the sealing pin in the area where the sealing pins are arranged densely.

[0062] The second state can be a plug-in state, in which the suction pin nozzle 12 of the suction pin assembly 10 is flush with the limiting member 30 or retracted into the limiting member 30. In this case, the sealing pin can be inserted into the liquid injection hole to a predetermined depth by the limiting member 30 adhering to the top of the battery.

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

[0064] In some embodiments of the present application, the suction pin assembly 10 is movable in the first direction, and the plug-in module further comprises a driving member 40, which is provided on the floating seat 21, and the driving member 40 is connected with the suction pin assembly 10, and the driving member 40 is used to drive the suction pin assembly 10 to move in the first direction.

[0065] Specifically, as shown in Figure 1 the floating seat 21 is fixedly connected with the driving member 40, which can be a pneumatic cylinder, the output end of the driving member 40 is movable in the first direction, the suction pin assembly 10 is connected with the output end of the driving member 40, the output end of the driving member 40 is switchable between the suction pin position and the plug-in position, and the driving member 40 can drive the suction pin assembly 10 to move in the first direction, so that the plug-in module can be switched between the first state (i.e., the output end of the driving member 40 is in the suction pin position) and the second state (i.e., the output end of the driving member 40 is in the plug-in position), and by adjusting the position of the suction pin assembly 10 in the first direction, the plug-in module can be adapted to different models of batteries and sealing pins, which is simple in structure and convenient for production and assembly.

[0066] As shown in Figure 1 in some optional examples of the present application, one side of the driving member 40 is provided with a magnetic switch 41, by which the suction pin position and the plug-in position of the driving member 40 can be detected.

[0067] According to an embodiment of the present application, the limiting member 30 is configured as a guide sleeve, the limiting member 30 is fixedly connected with the floating seat 21, and the limiting member 30 is sleeved on the suction pin assembly 10.

[0068] That is, as shown in Figure 1 , the limiting member 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 limiting member 30 is fixedly connected with the floating seat 21, and the limiting member 30 is sleeved on the suction pin assembly 10, so that the limiting member 30 can guide the suction pin assembly 10, thereby ensuring the stability of the movement of the suction pin assembly 10, and further improving the yield of the pin insertion.

[0069] In some embodiments of the present application, the pin insertion module further comprises a floating joint 50, the floating joint 50 comprising a first connecting part 51 and a second connecting part 52 relatively movable along a second direction, the first connecting part 51 being connected with the driving member 40, and the second connecting part 52 being connected with the suction pin assembly 10.

[0070] In other words, as shown in Figure 1 , the driving member 40 and the suction pin assembly 10 can be connected together through the floating joint 50. Specifically, the floating joint 50 comprises the first connecting part 51 and the second connecting part 52, wherein the first connecting part 51 is fixedly connected with the driving member 40, the first connecting part 51 is movably arranged in the second connecting part 52 along the second direction, the second direction is perpendicular to the first direction (for example, it can be the radial direction of the limiting member 30), and the second connecting part 52 is fixedly connected with the suction pin seat 11 of the suction pin assembly 10.

[0071] In this embodiment, the floating joint 50 can compensate for the installation error or slight displacement during operation to some extent, so as to ensure the stability of the suction pin assembly 10 during operation.

[0072] According to an embodiment of the present application, the floating seat 21 comprises a first mounting plate 211, the driving member 40 is arranged on one 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 through 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 suction pin assembly 10 is located between the first mounting plate 211 and the second mounting plate 212, the suction pin nozzle 12 of the suction pin 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, as shown in Figure 1As shown, the floating seat 21 mainly comprises a first mounting plate 211 and a second mounting plate 212, wherein the first mounting plate 211 is spaced apart from the second mounting plate 212 along the first direction, and two connecting pieces 213 are arranged between the first mounting plate 211 and the second mounting plate 212, the connecting pieces 213 are configured as connecting columns extending along the first direction, the first ends of the connecting pieces 213 are fixedly connected with the first mounting plate 211, and the second ends of the connecting pieces 213 are fixedly connected with the second mounting plate 212. The first mounting plate 211 is located on the side of the second mounting plate 212 close to the base 20, and the first mounting plate 211 is fixedly connected with the guide rod 22. The driving member 40 is fixedly connected on the 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] As shown in the drawings, Figure 1 The suction needle seat 11 of the suction needle 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 and is connected with the suction needle assembly 10. The suction needle nozzle 12 of the suction needle 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 suction needle nozzle 12 can suck the sealing needle and insert the sealing needle into the liquid injection hole of the battery. The limiting member 30 is fixedly connected on the side of the second mounting plate 212 away from the first mounting plate 211, so that the sealing needle can be inserted into the liquid injection hole to a predetermined depth by abutting the top of the battery through the limiting member 30.

[0075] In some embodiments of the present application, the needle insertion module further comprises a stopper 60 arranged on the suction needle assembly 10, the position of the stopper 60 in the first direction is adjustable, and the stopper 60 is used in cooperation with the first mounting plate 211 to limit the position of the suction needle assembly 10.

[0079] According to an embodiment of the present application, the stopper 60 is configured as a screw, and the screw is threadedly connected with 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, which is simple in structure and easy to operate.

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.

[0085] like ​ As 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.

[0086] 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.

[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 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, it controls the output end of the nail insertion drive unit 75 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.

[0088] Embodiments of the present invention also provide a pinning method, wherein the pinning device 100 of any of the above embodiments is used to pin the battery, and the pinning method includes: S100 to S400.

[0089] S100: Transport the battery to the insertion station;

[0090] Specifically, when the battery is inserted, the battery can be conveyed to a predetermined insertion station by the conveying device.

[0091] S200, sucking the sealing nail by the nail sucking assembly 10;

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

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

[0094] Specifically, after the nail sucking is completed, the multi-axis robot device 70 can drive the nail insertion module to move to the top of the liquid injection hole (i.e., the 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 as a reference, so that the limiting piece 30 is attached to the battery, and the sealing nail is inserted into the liquid injection hole of the battery to a predetermined depth by the movement of the base 20.

[0096] That is, 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, which is used as a reference to drive the base 20 to move along the first direction, so that the limiting piece 30 can not only be attached to the top of the highest battery, but also be attached to the top of the lowest battery. During the nail insertion process, if the battery is higher than the lowest battery, the limiting piece 30 abuts against the top of the battery, and the nail sucking assembly 10 moves upward relative to the output end of the nail insertion driving unit 75. If the nail insertion is performed on the lowest battery, the limiting piece 30 is just attached to the top of the battery or abuts against the top of the battery when the sealing nail is inserted to the predetermined depth.

[0097] Therefore, according to the nail insertion method provided in the embodiment, when the batteries with different heights are inserted, the sealing nail can be inserted to the predetermined depth, effectively avoiding the problems of over-insertion or insufficient insertion of the sealing nail caused by the size error of the battery, significantly improving the yield of the nail insertion, and further improving the production efficiency and product quality.

[0098] It should be noted that the size error existing in the battery manufacturing process causes the battery height to fluctuate within a certain range. The lowest battery refers to the battery with the smallest height in the batch, and the highest battery refers to the battery with the largest height.

[0099] In the above embodiments, the differences between the various embodiments are mainly described, and the optimization features different between the various embodiments can be combined to form a more optimal embodiment as long as they are not contradictory. Considering the brevity of the writing, the details are not repeated here.
