[0044] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0045] Reference Figure 1-Figure 5 , a battery pre-pressed nail system, comprising: at least two sets of nail feeding mechanisms 1, at least two sets of nail grabbing mechanisms 2, a nail buffering mechanism 3 having more than two nail buffering positions 311, a nail inserting mechanism 4 having more than two nail taking nozzles 41, and a battery transmission mechanism 5;

[0046] Wherein, the nail feeding mechanism 1 is used to feed sealing nails;

[0047] The nail grabbing mechanism 2 is used to grab the sealing nail in the corresponding nail feeding mechanism 1 and place the sealing nail into the nail buffer position 311;

[0048] The nail removal nozzle 41 is used to absorb the sealing nails on at least two of the nail buffer positions 311, and install the sealing nails into the unassembled batteries on the battery transmission mechanism 5 to form assembled batteries;

[0049] The battery transport mechanism 5 is used to transport the unassembled batteries and send out the assembled batteries.

[0050] At least two sets of nail feeding mechanisms 1 can simultaneously deliver sealing nails, and corresponding at least two sets of grabbing mechanisms 2 can simultaneously grab the sealing nails and place the sealing nails in the nail buffer mechanism 3 at the same time, which can reduce the risk of the entire system shutting down due to the failure of a single nail feeding mechanism 1 or grabbing mechanism 2, and improve the reliability and stability of the system;

[0051] The nail insertion mechanism 4 takes the sealing nail on the nail buffer position 311 instead of directly taking nails from the nail feeding mechanism 1. Firstly, when the nail taking mouth 41 of the nail insertion mechanism 4 is stained with battery electrolyte, it can avoid that the nail taking mouth 41 contaminates the nail feeding mechanism 1, thereby reducing the probability of the nail feeding mechanism 1 being contaminated; secondly, during the high-speed operation of the system, the nail feeding mechanism 1 can continuously feed materials without waiting until the nail insertion mechanism 4 completes a round of battery assembly before continuing to feed materials, thereby improving the working efficiency of pre-pressing nails in the system.

[0052] In this embodiment, an unassembled battery refers to a battery whose liquid injection hole is not equipped with a sealing nail. An assembled battery refers to a battery whose liquid injection hole is equipped with a sealing nail. The sealing nail can be a component that can block the liquid injection hole to maintain the airtightness requirement of the liquid injection hole, for example, a rubber nail, a plastic nail, a metal nail, etc.

[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 vibration plate 13 and a counting device 14. The feeding box 1 is inclined 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, and the several sealing nails are arranged on the same plane through vibration and discharged into the flexible vibration plate 13. Several nail grooves 131 are provided at the bottom of the flexible vibration plate 13. The flexible vibration plate 13 vibrates so that one nail groove 131 corresponds to one sealing nail. The counting device 14 is provided on the upper part of the flexible vibration plate 13 to identify the number of effective nails in the flexible vibration plate 13. When the effective nails meet a certain amount, the nail grabbing mechanism 2 operates to grab the sealing nails; if the number of effective nails in the flexible vibration plate 13 is insufficient, the flexible vibration plate 13 and the feeding bin 12 vibrate the incoming 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 metal hydride battery, a nickel cadmium battery, a lead storage battery, etc., but the embodiments of the present application are not limited to this.

[0056] As an example, the battery may include a housing. The housing is used to encapsulate components such as electrode components and electrolytes. The housing may be a steel housing, an aluminum housing, a plastic housing (such as polypropylene), a composite metal housing (such as a copper-aluminum composite housing), or an aluminum-plastic film.

[0057] As an example, the battery can be a high-beat cylindrical battery, a cylindrical battery, a prismatic battery, a soft-pack battery or a battery of other shapes. The prismatic battery includes a square shell battery, a blade-shaped battery, a polygonal prismatic battery, such as a hexagonal prismatic battery, etc. There is no special limitation in the present application.

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

[0059] In the prior art, nailing positions are all set at positions outside the battery transmission mechanism, so that unassembled batteries need to be moved manually / mechanically from the battery transmission mechanism to the nailing position, and assembled batteries are unloaded after assembly is completed; in this process, unassembled batteries move, and electrolyte leakage from the injection hole is easy to occur if there is a slight carelessness, and the unassembled batteries move, which increases the probability of the reference change of the injection hole. If the battery injection hole cannot be accurately placed on the nailing position, or the unassembled battery is tilted, the reference of the injection hole will be uneven, and the nail insertion mechanism set by the program will not be able to accurately pre-press the nail, which reduces the efficiency of pre-pressing the nail on the one hand, and increases the probability of electrolyte contamination and battery scrapping on the other hand;

[0060] Reference Figure 2 , Figure 3 , Figure 6 , Figure 7 as well as Fig.12 In order to solve the above technical problems, in one embodiment, the battery transmission mechanism 5 has a nailing position 51, a nail removal position 30 is provided between the battery transmission mechanism 5 and the nail feeding mechanism 1, the nail buffer position 311 is also provided between the battery transmission mechanism 5 and the nail feeding mechanism 1, and the nail removal position 30 is provided on a side close to the battery transmission mechanism 5; the nail insertion mechanism 4 includes a Z-axis lifting group 43 and a first Y-axis lateral movement group 45; the Z-axis lifting group 43 is used to drive the nail removal mouth 41 to move up and down to absorb the sealing nail on the nail removal position 30 and install the sealing nail on the unassembled battery; the first Y-axis lateral movement group 45 is used to drive the nail removal mouth 41 to move back and forth between the nailing position 51 and the nail removal position 30.

[0061] In this embodiment, the nailing position 51 is located on the battery transmission 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 nailing positions 51 and nailing positions 30 is multiple and equal, and one nailing position 51 is used to place one or more unassembled batteries / unassembled batteries.

[0063] It can be understood that after the nail buffer mechanism 3 is filled with the sealing nails, the nail buffer mechanism 3 drives multiple sealing nails to move to the nail removal position 30, waiting for the nail insertion mechanism 4 to remove the nails; when the nail removal mouth 41 is located at the nail removal position 30, the Z-axis lifting group 43 drives the nail removal mouth 41 to descend to remove the nails, and the Z-axis lifting group 43 drives the nail removal mouth 41 to reset. At this time, the nail buffer mechanism 3 in the nail removal position 30 is in a state of no nails, and the actions of resetting the nail buffer mechanism 3 and driving the nail removal mouth 41 to move to the nail insertion position 51 by the first Y-axis lateral movement group 45 can be completed at the same time. It can be seen that compared with the movement of the nail removal mouth 41 to the nail buffer position 311 to wait for nail removal, setting the nail removal position 30 can reduce the moving path of the nail removal mouth 41, and shorten the storage time of the sealing nails in the nail buffer position 311, which helps to further improve the working efficiency of pre-pressing nails.

[0064] Specifically, the first Y-axis lateral shifting group 45 can be two groups, which are respectively arranged on the left and right sides of the Z-axis lifting group 43 and the nail removal mouth 41, and the first Y-axis lateral shifting group 45 is slidably connected to the nail removal mouth 41 and the Z-axis lifting group 43; the Z-axis lifting group 43 drives the nail removal mouth 41 to move up and down between the two first Y-axis lateral shifting groups 45, so as to absorb the sealing nail on the nail removal position 30, and install the sealing nail on the unassembled battery;

[0065] More specifically, the nail driving position 51 and the nail removing position 30 are located between the two first Y-axis lateral shifting groups 45;

[0066] As an example, the Z-axis lifting group 43 includes a Z-axis lifting drive 431, the number of which is one, and the output end of the Z-axis lifting drive 431 is connected to multiple nail removal nozzles 41. The output end of the Z-axis lifting drive 431 extends out to drive all the nail removal nozzles 41 to move up and down synchronously.

[0067] As an example, the Z-axis lifting group 43 includes multiple Z-axis lifting drive components 431, and the output ends of the Z-axis lifting drive components 431 are connected one-to-one with the nail removal mouths 41. In this way, each nail removal mouth 41 is in a state of being individually controlled by the Z-axis lifting drive component 431, which is convenient for selecting the number of nail removal mouths 41 to be driven according to production scale requirements. At this time, the first Y-axis lateral movement group 45 drives all Z-axis lifting groups 43 to move synchronously.

[0068] More specifically, the first Y-axis lateral shifting group 45 and the Z-axis lifting group 43 are common transmission structures in the art, such as belt transmission, screw transmission, slider and rail matching transmission, cylinder transmission, etc.

[0069] Specifically, a nail removal mouth cleaning mechanism 6 is provided between the nail driving position 51 and the nail removal position 30 , and the nail removal mouth cleaning mechanism 6 is arranged below the first Y-axis lateral shift group 45 , and the nail removal mouth cleaning mechanism 6 is provided with at least cleaning positions 61 corresponding to the number of the nail removal mouths 41 .

[0070] During the operation of the system, the nail taking mouth 41 is easily stained with electrolyte, and the electrolyte causes crystallization at the nail suction port, resulting in blockage of the nail suction port; therefore, a nail taking mouth cleaning mechanism 6 is provided to clean the stained electrolyte in time;

[0071] The nail removal nozzle cleaning mechanism 6 is arranged between the nail driving position 51 and the nail removal position 3, that is, on the moving path of the nail insertion mechanism 4. The nozzle cleaning route and the route from nail driving to nail removal are overlapped, which saves the additional drive structure setting, makes the structure of the system more compact, and further reduces the manufacturing cost.

[0072] The number of cleaning positions 61 corresponds to the number of nail removal nozzles 41, that is, when the nail insertion mechanism 4 moves above the cleaning position 61, it only needs the Z-axis lifting group 43 to drive the nail removal nozzle 41 to move up and down, and the nail removal nozzle 41 can be quickly inserted into the cleaning position 61, which is convenient for the operation of the nail removal nozzle cleaning mechanism 6; this makes the structure of the system more compact, and is particularly suitable for high-speed pre-pressing nail operations.

[0073] It can be understood that the nail removal mouth cleaning mechanism 6 is arranged below the nail insertion mechanism 4.

[0074] In the prior art, the contact surface between the nail grabbing nozzle 21 and the sealing nail has a concave step structure, the purpose of which is to wrap the tail of the sealing nail in the concave step structure. The concave step structure needs to be concentric with the sealing nail so that the nail grabbing nozzle 21 can accurately grab the sealing nail; however, when taking nails in actual working conditions, it is impossible to completely ensure that the sealing nail and the nail grabbing nozzle 21 are completely concentric, so it is difficult to ensure that the sealing nail is completely sucked into the concave step structure, especially when multiple nail grabbing nozzles 21 are driven by a Z-axis lifting drive 431, if one of the sealing nails is staggered from the concave step structure, the sealing nail resists the output end extension of the Z-axis lifting drive 431, so that all the nail grabbing nozzles 21 cannot grab the sealing nail. During the high-speed operation, the unassembled batteries corresponding to this nail removal process remain in an unassembled state and flow out of the system, and the unassembled batteries need to be manually screened out later, which affects the battery production operation;

[0075] Reference Figure 3In order to solve the above problem, in one embodiment, the nail grabbing mechanism 2 includes a plurality of nail grabbing nozzles 21, and the surface of the nail grabbing nozzle 21 in contact with the sealing nail is a plane, and the suction port of the nail grabbing nozzle 21 is smaller than the cross section of the sealing nail. The surface of the nail grabbing nozzle 21 in contact with the nail is a plane, and the nail grabbing nozzle 21 can be compatible with the sealing nail that is not concentric with it when taking the nail, and the injection hole is concave toward the battery, and the sealing nail has a tail embedded in the injection hole. During the nail pressing process, as long as the tail of the sealing nail is partially embedded in the concave part of the battery, the injection hole can also be smoothly sealed, and the nail grabbing nozzle 21, the injection hole, and the nail have good compatibility.

[0076] In one embodiment, the nail removing nozzle 41 has the same structure as the nail grabbing and sucking nozzle 21 .

[0077] Reference Figure 4 , Figure 8 In one embodiment, the nail grabbing mechanism 2 includes a plurality of nail grabbing nozzles 21, and the number of the nail buffer positions 311 is at least twice that of the nail grabbing nozzles 21; the nail buffer mechanism 3 can cache more sealing nails to provide sufficient sealing nail supply for the subsequent nail insertion mechanism 4 to maintain production continuity.

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

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

[0080] More specifically, the multiple nail grabbing suction nozzles 21 are arranged in a straight line on the nail grabbing mechanism 2, and the nail grabbing mechanism 2 drives the multiple nail grabbing suction nozzles 21 to move synchronously. The nail buffer position 311, the nail driving position 51, and the nail removal position 30 are also arranged in a straight line. The straight line arrangement can make the system structure more compact and reduce the footprint of the equipment.

[0081] In one embodiment, the transmission direction of the battery transmission mechanism 5 is perpendicular to the moving direction of the nail grabbing mechanism 2. This can reduce the mutual interference between the battery transmission route and the nail grabbing route, and improve the stability and reliability of the system.

[0082] In one embodiment, the transmission path of the battery transmission mechanism 5 is a straight line, and the arrangement directions of the nail buffer positions 311 and the nail removal nozzles 41 are parallel to the transmission direction of the battery transmission mechanism 5, thereby further improving the compactness of the system structure.

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

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

[0085] The battery placement group 52 and the blank area 53 are arranged alternately. When nailing, the battery placement group 52 is located on the nailing position 51, and the battery transmission mechanism 5 stops waiting for the nail insertion mechanism 4 to nail. After the nailing is completed, the nailing mechanism 4 moves to the nail removal position 30 for drive, and the battery transmission mechanism 5 is started at the same time. The blank area 53 is located on the nailing position 51, which can just fill the time occupied by the nail insertion mechanism 4 reciprocating between the nailing position 51 and the nail removal position 30. When the nail insertion mechanism 4 moves to the nailing position 51 for the next round, the battery placement group 52 can also be located on the nailing position 51, which can ensure that the nail insertion mechanism 4 operates uninterruptedly, further improving the nailing efficiency of the device.

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

[0087] Reference Fig.10 , Fig.11 Specifically, the nail cache mechanism 3 includes a second Y-axis lateral shift group 33, a third Y-axis lateral shift group 34, a first cache group 31 provided with a plurality of the nail cache positions 311, and a second cache group 32 provided with a plurality of the nail cache positions 311;

[0088] The second Y-axis lateral shifting group 33 is used to drive the first buffer group 31 to reciprocate between the nail taking position 30 and the nail feeding mechanism 1;

[0089] The third Y-axis lateral shifting group 34 is used to drive the second buffer group 32 to reciprocate between the nail taking position 30 and the nail feeding mechanism 1;

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

[0091] The first cache group 31 and the second cache group 32 are set to increase the number of cache nails of the nail cache mechanism 3. When the first cache group 31 is full of sealing nails, the second Y-axis lateral movement group 33 drives the first cache group 31 to move to the nail removal position 30 for the nail insertion mechanism 4 to take the sealing nails; at the same time, the nail grabbing mechanism 2 places the captured sealing nails on the second cache group 32. When the second cache group 32 is full of sealing nails, the first cache group 31 is pushed out of the nail removal position 30 and the second cache group 32 is moved to the nail removal position 30 for the nail insertion mechanism 4 to take the sealing nails; this can ensure that the nail grabbing mechanism 2 and the nail feeding mechanism 1 can work continuously, further improving the pre-pressing nail efficiency of the system.

[0092] More specifically, the second Y-axis lateral shift group 33 and the third Y-axis lateral shift group 34 are common transmission structures in the art, such as belt transmission, screw transmission, slider and rail transmission, cylinder transmission, etc.

[0093] Reference Figure 2 In one embodiment, the nail insertion mechanism 4 further includes limiters 42 disposed on both sides of the nail removal mouth 41, and the horizontal position of the nail removal mouth 41 is higher than the limiters 42. The pre-stressed nail nailing mechanism 9 controls the insertion depth of each battery pre-stressed nail to be consistent through the fixed position difference between the limiters 42 and the nail removal mouth 41; the limiters 42 are disposed on both sides of the nail removal mouth 41, which helps to stabilize the relative position of the nail removal mouth 41 and the unassembled battery, and ensure that the nail removal mouth 41 accurately installs the nail into the injection hole.

[0094] Specifically, the end of the limiting member 42 that abuts against the battery contacts the battery surface, which can reduce the possibility of damaging the battery during the pre-pressing process and is less likely to cause scratches or deformation on the battery surface.

[0095] More specifically, the end of the limiting member 42 that abuts against the battery is rounded to further reduce the probability of scratching the battery surface.

[0096] It can be understood that the nail grabbing suction nozzle 21 and the nail removing nozzle 41 are each connected to a vacuum pump (not shown in the figure), and the vacuum pump provides power for the nail grabbing suction nozzle 21 and the nail removing nozzle 41 to ensure that the nail grabbing suction nozzle 21 and the nail removing nozzle 41 can absorb the sealing nail; more specifically, the vacuum pump is connected to a vacuum breaker (not shown in the figure), and the vacuum breaker breaks the negative pressure state of the nail grabbing suction nozzle 21 and the nail removing nozzle 41, and the nail grabbing suction nozzle 21 and the nail removing nozzle 41 release the grip of the sealing nail; the sealing nail is removed by the negative pressure of the vacuum pump, and the vacuum breaker breaks the vacuum by positive pressure, which greatly improves the efficiency of removing and inserting nails;

[0097] As an example, the vacuum breaking component is a solenoid valve.

[0098] More specifically, the nail insertion mechanism 4 also includes a fixed panel 46, the Z-axis lifting group 43 is arranged on the fixed panel 46, the Z-axis lifting group 43 includes a first slide rail 461 arranged on the fixed panel 46 and a first slider 462 sliding on the first slide rail 461, the first slider 462 is fixedly connected with a first fixed block 471, the first fixed block 471 is threadedly connected with a screw 472, the first fixed block 471 is fixed with a second slide rail, the second slide rail is slidably provided with a second slider 482, the nail removal mouth 41 and the limiter 42 are both fixed on the second slider 482, and one end of the screw 472 is fixedly connected with the second slider 482;

[0099] By rotating the screw 472, the position of the second slider 482 on the first fixed block 471 can be adjusted, and the screw 472 is threadedly locked with the first fixed block 471 to fix the position of the second slider 482 on the first fixed block 471; the thread can meet the need for fine adjustment and adjust the position of the second slider 482 on the first fixed block 471 to adapt to different models of batteries and sealing nails.

[0100] More specifically, a driving cylinder 49 is also connected to the first slider 462, and the driving cylinder 49 drives the first slider 462 to move on the first slide rail 461; and the driving cylinder 49 also has a buffering function. In the prior art, the buffer between the nail mouth and the battery is a spring, the purpose of which is to avoid collision between the nail mouth and the battery. As time goes by, dust will fall off the spring due to friction, and the elastic force will change or fail, thereby affecting the buffering effect; in this embodiment, a driving cylinder 49 is used instead of a spring to ensure that when the limit member 42 contacts the battery, the force will not cause battery loss due to excessive impact force, and the limit member 42 has a certain floating amount.

[0101] More specifically, the driving cylinder 49 is connected to a pressure regulating valve (not shown in the figure), which adjusts the output pressure of the driving cylinder 49 to further ensure that when the limit member 42 contacts the battery, the force will not cause battery loss due to excessive impact force.
