[0044] The concept, specific structure and technical effects of the present application will be described clearly and completely in combination with the embodiments and drawings, so as to fully understand the purpose, features and effects of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments, and other embodiments obtained by those skilled in the art without creative labor based on the embodiments of the present application all belong to the scope of protection of the present application. In addition, all the coupling / connection relations involved in the patent do not mean that the components are directly connected, but that a better coupling structure can be composed by adding or reducing coupling accessories according to the specific implementation situation. The technical features in the present application can be combined interactively without mutual contradiction and conflict.

[0045] REFERENCE Figures 1-5 A battery pre-pressing nail system, comprising: at least two groups of nail feeding mechanisms 1, at least two groups of nail grabbing mechanisms 2, a nail caching mechanism 3 with two or more nail caching positions 311, a nail inserting mechanism 4 with two or more nail taking nozzles 41, and a battery transferring mechanism 5;

[0046] The nail feeding mechanism 1 is used for conveying sealing nails.

[0047] Along the length direction of the nail caching mechanism 3, the nail grabbing mechanism 2 is arranged on both sides of the nail caching mechanism 3, and is used for grabbing the sealing nails in the corresponding nail feeding mechanism 1 and placing the sealing nails into the nail caching positions 311 on both sides of the nail caching mechanism 3.

[0048] The nail-removing nozzle 41 is used to pick up at least two of the sealing nails on the nail buffer positions 311 and install the sealing nails into the unassembled battery on the battery transfer mechanism 5 to form an assembled battery.

[0049] The battery transfer mechanism 5 is used to transfer the unassembled battery and to deliver the assembled battery.

[0050] At least two sets of nail feeding mechanisms 1 can simultaneously deliver sealing nails, and at least two sets of corresponding gripping mechanisms 2 can simultaneously grip the sealing nails and place the sealing nails on the nail buffer positions 311 on both sides of the nail buffer mechanism 3 along the length direction of the nail buffer mechanism 3. This can reduce the risk of the entire system shutting down due to the failure of a single nail feeding mechanism 1 or gripping mechanism 2. Moreover, compared to the nail gripping mechanism 2 being set on one side of the nail buffer mechanism 3, it reduces the interference that occurs when the gripping mechanism 2 grips the sealing nails, thereby improving the reliability and stability of the system.

[0051] The nail insertion mechanism 4 retrieves the sealing nail from the nail buffer position 311 instead of directly from the nail feeding mechanism 1. Firstly, when the nail retrieval nozzle 41 of the nail insertion mechanism 4 is contaminated with battery electrolyte, it can prevent the nail retrieval nozzle 41 from contaminating the nail feeding mechanism 1, reducing the probability of the nail feeding mechanism 1 being contaminated. Secondly, during high-speed operation of this system, the nail feeding mechanism 1 can continuously feed materials without waiting for the nail insertion mechanism 4 to finish assembling a round of batteries before continuing to feed materials, thereby improving the working efficiency of the pre-pressed nails in this system.

[0052] In this embodiment, an unassembled battery refers to a battery whose electrolyte filling hole is not fitted with a sealing pin. An assembled battery refers to a battery whose electrolyte filling hole is fitted with a sealing pin. The sealing pin can be a component capable of sealing the electrolyte filling hole to maintain the required airtightness, such as a rubber pin, plastic pin, or metal pin.

[0053] Reference Figure 5 , Figure 6 As an example, the nail feeding mechanism 1 includes a feeding box 11, a feeding bin 12, a flexible vibrating plate 13, and a counting device 14. The feeding box 1 is tilted at 45 degrees. Under the action of gravity, several sealing nails are poured into the feeding bin 12 along the feeding box 11. The feeding bin 12 vibrates, arranging the sealing nails on the same plane and feeding them into the flexible vibrating plate 13. The bottom of the flexible vibrating plate 13 is provided with several nail slots 131. The vibration of the flexible vibrating plate 13 causes one sealing nail to be installed in each nail slot 131. The counting device 14 is located on the upper part of the flexible vibrating plate 13 to identify the number of effective nails in the flexible vibrating plate 13. When the number of effective nails is sufficient, the nail gripping mechanism 2 operates to grip the sealing nails. If the number of effective nails in the flexible vibrating plate 13 is insufficient, the flexible vibrating plate 13 and the feeding bin 12 vibrate to feed the materials.

[0054] The counting device 14 is a CCD camera.

[0055] As an example, the battery can be a lithium ion battery, a sodium ion battery, a sodium lithium ion battery, a lithium metal battery, a sodium metal battery, a lithium sulfur battery, a magnesium ion battery, a nickel hydrogen battery, a nickel cadmium battery, a lead-acid battery, etc. The embodiments of the present application are not limited thereto.

[0056] As an example, the battery can include a shell. The shell is used to package components such as the electrode assembly and the electrolyte. The shell can be a steel shell, an aluminum shell, a plastic shell (such as polypropylene), a composite metal shell (such as a copper-aluminum composite shell), or an aluminum-plastic film, etc.

[0057] As an example, the battery can be a high-beat cylindrical battery, a cylindrical battery, a prismatic battery, a soft-pack battery, or other shaped batteries. The prismatic battery includes a square battery, a blade-shaped battery, a multi-prismatic battery, such as a hexagonal prismatic battery, etc. The present application is not particularly limited.

[0058] As an example, the grabbing mechanism 2 can be a four-axis robot, a six-axis robot, etc., which can be used to grab and release the sealing nails at high speed.

[0059] In the prior art, the nailing position is arranged outside the battery conveying mechanism. Therefore, it is necessary to manually / mechanically transport the un-assembled battery from the battery conveying mechanism to the nailing position, and after assembly, the assembled battery is discharged. In this process, the un-assembled battery moves, and if not careful, it is easy to cause the electrolyte to leak from the liquid injection hole. Moreover, the un-assembled battery moves, increasing the probability of the change of the reference of the liquid injection hole. For example, if the battery liquid injection hole cannot be accurately placed on the nailing position, or the un-assembled battery is tilted, it will cause the reference of the liquid injection hole to be uneven, and the pre-nailing mechanism set by the program will not be able to accurately pre-press the nail, on the one hand, reducing the pre-nailing efficiency, on the other hand, increasing the probability of electrolyte pollution and battery scrap.

[0060] Referring to Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 12In order to solve the above technical problems, in an embodiment, the nail striking position 51 is arranged on the battery conveying mechanism 5, the nail taking position 30 is arranged between the battery conveying mechanism 5 and the nail feeding mechanism 1, the nail buffer position 311 is also arranged between the battery conveying mechanism 5 and the nail feeding mechanism 1, and the nail taking position 30 is arranged on the side close to the battery conveying mechanism 5; the nail inserting mechanism 4 comprises a Z-axis lifting group 43 and a first Y-axis horizontal moving group 45; the Z-axis lifting group 43 is used to drive the nail taking nozzle 41 to move up and down to suck the sealing nails on the nail taking position 30 and install the sealing nails on the un-assembled battery; the first Y-axis horizontal moving group 45 is used to drive the nail taking nozzle 41 to reciprocate between the nail striking position 51 and the nail taking position 30.

[0061] In the embodiment, the nail striking position 51 is arranged on the battery conveying mechanism 5, and the battery does not move during the sealing nail assembly process, thereby improving the pre-pressing nail efficiency.

[0062] It can be understood that the number of the nail striking positions 51 and the number of the nail taking positions 30 are equal, and one nail striking position 51 is used to place one or more un-assembled batteries / assembled batteries.

[0063] It can be understood that when the nail buffer mechanism 3 is full of the sealing nails, the nail buffer mechanism 3 drives a plurality of sealing nails to move to the nail taking position 30 to wait for the nail inserting mechanism 4 to take the nails; when the nail taking nozzle 41 is located at the nail taking position 30, the Z-axis lifting group 43 drives the nail taking nozzle 41 to descend to take the nails, and then the Z-axis lifting group 43 drives the nail taking nozzle 41 to reset, at this time, the nail buffer mechanism 3 in the nail taking position 30 is in a state of no nails, and the actions of the resetting of the nail buffer mechanism 3 and the driving of the first Y-axis horizontal moving group 45 to move the nail taking nozzle 41 to the nail striking position 51 can be completed at the same time. Compared with the action of moving the nail taking nozzle 41 to the nail buffer position 311 to wait for taking the nails, the arrangement of the nail taking position 30 can reduce the moving path of the nail taking nozzle 41 and shorten the storage time of the sealing nails in the nail buffer position 311, which is helpful to further improve the working efficiency of the pre-pressing nail.

[0064] Specifically, the first Y-axis horizontal moving group 45 can be two groups, which are arranged on the left and right sides of the Z-axis lifting group 43 and the nail taking nozzle 41, and the first Y-axis horizontal moving group 45 is slidably connected with the nail taking nozzle 41 and the Z-axis lifting group 43; the Z-axis lifting group 43 drives the nail taking nozzle 41 to move up and down between the two first Y-axis horizontal moving groups 45, thereby sucking the sealing nails on the nail taking position 30 and installing the sealing nails on the un-assembled battery.

[0065] More specifically, the nail striking position 51 and the nail taking position 30 are located between the two first Y-axis horizontal moving groups 45.

[0066] As an example, the Z-axis lifting group 43 includes a Z-axis lifting drive 431, the number of Z-axis lifting drives 431 is one, and the output end of the Z-axis lifting drive 431 is connected to a plurality of nail taking nozzles 41, and the output end of the Z-axis lifting drive 431 is extended to drive all the nail taking nozzles 41 to move up and down synchronously.

[0067] As an example, the Z-axis lifting group 43 includes a plurality of Z-axis lifting drives 431, the output end of the Z-axis lifting drive 431 is connected to the nail taking nozzle 41 one by one, in this way, each nail taking nozzle 41 is in a state of being controlled by the Z-axis lifting drive 431 alone, facilitating the selection of the number of nail taking nozzles 41 to be driven according to the production scale, at this time, the first Y-axis transverse moving group 45 drives all the Z-axis lifting groups 43 to move synchronously.

[0068] More specifically, the first Y-axis transverse moving group 45 and the Z-axis lifting group 43 are common transmission structures in the art, such as belt transmission, screw transmission, slider and slide rail cooperation transmission, and cylinder transmission.

[0069] Specifically, the nail taking nozzle cleaning mechanism 6 is arranged between the nail driving position 51 and the nail taking position 30, the nail taking nozzle cleaning mechanism 6 is arranged below the first Y-axis transverse moving group 45, and the nail taking nozzle cleaning mechanism 6 is provided with at least a cleaning position 61 corresponding to the number of nail taking nozzles 41.

[0070] In the operation process of the system, the nail taking nozzle 41 is easy to be stained with electrolyte, and the electrolyte causes crystallization at the suction nozzle, resulting in blockage of the suction nozzle; therefore, the nail taking nozzle cleaning mechanism 6 is arranged to clean the electrolyte stained thereon in time;

[0071] The nail taking nozzle cleaning mechanism 6 is arranged between the nail driving position 51 and the nail taking position 30, that is, on the moving path of the nail inserting mechanism 4, the suction nozzle cleaning path and the path from nail driving to nail taking are coincident, saving the setting of additional driving structure, the structure of the system is more compact, and the manufacturing cost is further reduced;

[0072] The number of cleaning positions 61 corresponds to the number of nail taking nozzles 41, that is, when the nail inserting mechanism 4 moves above the cleaning position 61, only the Z-axis lifting group 43 is needed to drive the nail taking nozzle 41 to move up and down, the nail taking nozzle 41 can be quickly inserted into the cleaning position 61, facilitating the operation of the nail taking nozzle cleaning mechanism 6; the compactness of the structure of the system is stronger, and it is especially suitable for high-speed pre-pressing nail operation.

[0073] It can be understood that the nail taking nozzle cleaning mechanism 6 is arranged below the nail inserting mechanism 4.

[0074] In the prior art, the contact surface of the nail grabbing suction nozzle 21 and the sealing nail has an inner recessed step structure, the purpose of which is to wrap the tail of the sealing nail inside the inner recessed step structure. The recessed step structure needs to be concentric with the sealing nail, so that the nail grabbing suction nozzle 21 can accurately grab the sealing nail. However, in actual working conditions, it is impossible to completely ensure that the sealing nail is concentric with the nail grabbing suction nozzle 21, so it is difficult to ensure that the sealing nail is completely sucked into the inner recessed step structure, especially when multiple nail grabbing suction nozzles 21 are driven by a Z-axis lifting drive 431. If one of the sealing nails is misaligned with the inner recessed step structure, the sealing nail abuts against the output end of the Z-axis lifting drive 431, so that all the nail grabbing suction nozzles 21 cannot grab the sealing nail. In the process of high-speed operation, the battery that is not assembled corresponding to this taking nail process still remains in the unassembled state and flows out of the system, which needs to be screened out by manual post-processing, affecting the production operation of the battery.

[0075] With reference to Figure 3 In order to solve the above problems, in an embodiment, the nail grabbing mechanism 2 comprises a plurality of nail grabbing suction nozzles 21, the contact surface of the nail grabbing suction nozzle 21 and the sealing nail is a plane, and the suction port of the nail grabbing suction nozzle 21 is smaller than the cross section of the sealing nail. The contact surface of the nail grabbing suction nozzle 21 and the nail is a plane, and the nail grabbing suction nozzle 21 can be compatible with the sealing nail that is not concentric with it when taking the nail. The liquid injection hole is recessed into the battery, the sealing nail has a tail that is embedded into the liquid injection hole, and during the pressing process, as long as the tail of the sealing nail is partially embedded into the recessed part of the battery, the liquid injection hole can be successfully sealed. The compatibility of the nail grabbing suction nozzle 21, the liquid injection hole and the nail is good.

[0076] In an embodiment, the structure of the nail taking nozzle 41 is the same as that of the nail grabbing suction nozzle 21.

[0077] With reference to Figure 4 、 Figure 8 In an embodiment, the nail grabbing mechanism 2 comprises a plurality of nail grabbing suction nozzles 21, and the number of the nail buffer positions 311 is at least twice the number of the nail grabbing suction nozzles 21. The nail buffer mechanism 3 can buffer more sealing nails to provide sufficient sealing nails for the subsequent nail inserting mechanism 4, thereby maintaining the continuity of production.

[0078] It can be understood that the nail grabbing mechanism 2 described above refers to only one group, and does not represent all nail grabbing mechanisms 2 in the system.

[0079] In an embodiment, the number of the staple buffer positions 311 is equal to the number of the staple driving positions 51, the staple taking positions 30 and the staple taking nozzles 41; as an example, the number of the staple taking nozzles 21 is 1, 2, 3, 4, 5, 6, 7; the number of the staple buffer positions 311 is 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14; the number of the staple driving positions 51 is 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14; the number of the staple taking nozzles 41 is 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14.

[0080] More specifically, the plurality of the staple taking nozzles 21 are arranged in a straight line on the staple taking mechanism 2, the staple taking mechanism 2 drives the plurality of the staple taking nozzles 21 to move synchronously, and the staple buffer positions 311, the staple driving positions 51 and the staple taking positions 30 are also arranged in a straight line.

[0081] In an embodiment, the transmission direction of the battery transmission mechanism 5 is perpendicular to the moving direction of the staple taking mechanism 2. The mutual interference between the battery transmission route and the staple taking route can be reduced, and the stability and reliability of the system can be improved.

[0082] In an embodiment, the transmission path of the battery transmission mechanism 5 is a straight line, and the arrangement direction of the staple buffer positions 311 and the staple taking nozzles 41 is parallel to the transmission direction of the battery transmission mechanism 5. The compactness of the structure of the system is further improved.

[0083] It can be understood that the transmission path of the battery transmission mechanism 5 is a straight line, which only represents that the transmission path in the system is a straight line, i.e. the transmission path of the battery transmission mechanism 5 outside the system can be designed to be curved according to the site needs.

[0084] Reference Figure 8 In an embodiment, the battery transmission mechanism 5 comprises a transmission line 54, a battery placing group 52 and a blank area 53 arranged on the transmission line 54; the battery placing group 52 and the blank area 53 are arranged alternately, the battery placing group 52 has a plurality of battery placing positions 521, and the battery placing positions 521 are used to place the un-assembled batteries or the assembled batteries.

[0085] The battery placement group 52 is arranged alternately with the blank area 53. When nailing, the battery placement group 52 is located on the nailing position 51, the battery conveying mechanism 5 is stopped to wait for the nailing mechanism 4 to nail, after the nailing is completed, the nailing mechanism 4 moves to the nail taking position 30 to drive, at the same time, the battery conveying mechanism 5 is started, the blank area 53 is located on the nailing position 51, which can fill the time occupied by the nailing mechanism 4 reciprocating between the nailing position 51 and the nail taking position 30, when the nailing mechanism 4 moves to the nailing position 51 for the next round, the battery placement group 52 can be located on the nailing position 51 at the same time, which can ensure that the nailing mechanism 4 does not stop working, and further improves the nailing efficiency of the device.

[0086] It can be understood that, along the battery conveying direction, the battery placement group 52 in which the unassembled batteries are placed is located upstream of the nailing position 51, and the battery placement group 52 in which the assembled batteries are placed is located downstream of the nailing position 51.

[0087] Referring to Figure 10 , Figure 11 Specifically, the nail buffer mechanism 3 comprises a second Y-axis transverse movement group 33, a third Y-axis transverse movement group 34, a first buffer group 31 provided with a plurality of nail buffer positions 311, and a second buffer group 32 provided with a plurality of nail buffer positions 311.

[0088] The second Y-axis transverse movement group 33 is used to drive the first buffer group 31 to reciprocate between the nail taking position 30 and the nail conveying mechanism 1.

[0089] The third Y-axis transverse movement group 34 is used to drive the second buffer group 32 to reciprocate between the nail taking position 30 and the nail conveying mechanism 1.

[0090] The first buffer group 31 is located above the second buffer group 32.

[0091] The first buffer group 31 and the second buffer group 32 are arranged, which improves the number of nails buffered by the nail buffer mechanism 3, when the first buffer group 31 is full of sealed nails, the first buffer group 31 is driven by the second Y-axis transverse movement group 33 to move to the nail taking position 30 for the nailing mechanism 4 to take the sealed nails, at the same time, the sealed nails grabbed by the nail grabbing mechanism 2 are placed on the second buffer group 32, when the second buffer group 32 is full of sealed nails, the first buffer group 31 is pushed out of the nail taking position 30, and the second buffer group 32 moves to the nail taking position 30 for the nailing mechanism 4 to take the sealed nails, which can ensure that the nail grabbing mechanism 2 and the nail conveying mechanism 1 work continuously, and further improves the pre-nailing efficiency of the system.

[0092] More specifically, the second Y-axis transverse movement group 33 and the third Y-axis transverse movement group 34 are common transmission structures in the field, such as belt transmission, screw transmission, slider and slide rail cooperation transmission, and cylinder transmission.

[0093] Referring to Figure 2In an embodiment, the nail inserting mechanism 4 further comprises a limiting member 42 arranged on both sides of the nail taking nozzle 41, and the horizontal position of the nail taking nozzle 41 is higher than that of the limiting member 42. The nail inserting depth of each battery pre-pressing nail is consistent by the fixed position difference between the limiting member 42 and the nail taking nozzle 41. The limiting member 42 is arranged on both sides of the nail taking nozzle 41, which helps to stabilize the relative position between the nail taking nozzle 41 and the un-assembled battery, and ensures that the nail taking nozzle 41 accurately installs the nail into the liquid injection hole.

[0094] Specifically, the end of the limiting member 42 abutting against the battery is in contact with the surface of the battery, which can reduce the probability of damaging the battery during the pre-pressing nail process, and is not easy to cause scratches or deformation on the surface of the battery.

[0095] More specifically, the end of the limiting member 42 abutting against the battery is arranged with a rounded corner, which further reduces the probability of scratching the surface of the battery.

[0096] It can be understood that the nail grabbing suction nozzle 21 and the nail taking nozzle 41 are respectively connected with a vacuum pump (not shown in the figure), which provides power for the nail grabbing suction nozzle 21 and the nail taking nozzle 41 to ensure that the nail grabbing suction nozzle 21 and the nail taking nozzle 41 can suck the sealing nail; more specifically, the vacuum pump is connected with a vacuum breaking member (not shown in the figure), which breaks the negative pressure state of the nail grabbing suction nozzle 21 and the nail taking nozzle 41, and the nail grabbing suction nozzle 21 and the nail taking nozzle 41 release the grabbing of the sealing nail; the vacuum pump sucks the sealing nail by negative pressure, and the vacuum breaking member breaks the vacuum by positive pressure, which greatly improves the efficiency of nail taking and inserting;

[0097] As an example, the vacuum breaking member is an electromagnetic valve.
