[0023] The concept, specific structure and technical effects of the present application will be described clearly and completely in combination with the embodiments and the 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 connection / connection relationships involved in the patent do not mean that the components are directly connected, but that a better connection structure can be composed by adding or reducing connection auxiliary parts according to the specific implementation situation.

[0024] REFERENCE Figures 1-3 A nail suction nozzle device, comprising: a negative pressure generating mechanism, a nail suction nozzle 2 connected with the negative pressure generating mechanism; the negative pressure generating mechanism provides power for the nail suction nozzle to quickly and stably suck the sealing nail; the contact surface of the nail suction nozzle 2 with the sealing nail is a plane, and the nail suction nozzle can be compatible with sealing nails of different centers when taking nails, thereby improving the efficiency of taking nails.

[0025] As an example, the negative pressure generating mechanism is a vacuum pump;

[0026] 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 suction nozzle 2, and the nail suction nozzle 2 releases the grip on the sealing nail; the nail is sucked by the vacuum pump under negative pressure, and the vacuum breaking member breaks the vacuum under positive pressure, greatly improving the efficiency of taking and inserting the sealing nail;

[0027] As an example, the vacuum breaking member is a solenoid valve.

[0028] In an embodiment, it further comprises an auxiliary member 3 arranged on both sides of the nail suction nozzle 2, which is used to stabilize the nail suction nozzle 2 on the surface of the battery.

[0029] Taking the pre-pressing nail process as an example, the two auxiliary members 3 are arranged on the surface of the battery, and as long as the positions of the nail suction nozzle 2 and the auxiliary member 3 relative to the battery are set, the sealing nail can be quickly pre-pressed into the liquid injection hole of the battery; the auxiliary member 3 is arranged on both sides of the nail suction nozzle 2, which helps to stabilize the relative position of the nail suction nozzle 2 and the battery, and ensures that the reference between the nail suction nozzle 2 and the nail does not deviate during the nail taking process, and the relative position between the battery and the nail suction nozzle 2 is stable.

[0030] Further, the device further comprises a lifting mechanism 4, which is used to drive the nail taking nozzle 2 to lift. In an automatic or semi-automatic assembly line, the lifting mechanism 4 can match the nail taking nozzle device with the workstations at different heights on the assembly line, thereby improving the degree of automation and production efficiency.

[0031] Specifically, the lifting mechanism 4 comprises a first lifting assembly 41 and a fine adjustment assembly 42, the first lifting assembly 41 is used to drive the nail taking nozzle 2 and the auxiliary member 3 to lift synchronously, and the fine adjustment assembly 42 is used to adjust the height difference between the nail taking nozzle 2 and the auxiliary member 3.

[0032] In the pre-pressing step, the liquid injection hole level of the battery is generally lower than the upper surface of the battery, and the liquid injection hole level and the upper surface of the battery have slight differences between different batteries. By adjusting the height difference between the nail taking nozzle 2 and the auxiliary member 3 to the appropriate position through the fine adjustment assembly 42, batch pre-pressing operation can be performed on the same specification of batteries, and the probability of the nail taking nozzle 2 being contaminated by electrolyte in repeated operation can be reduced, and the occurrence of blockage can be reduced.

[0033] More specifically, the device further comprises a fixed panel 5, the first lifting assembly 41 comprises a lifting driving member 411, the fixed end of the lifting driving member 411 is arranged on the fixed panel 5, the output end of the lifting driving member 411 is connected with a sliding block 61 which slides on the fixed panel 5, and a first fixed block 71 perpendicular to the driving direction of the lifting mechanism 4 is fixedly connected on the sliding block 61.

[0034] The fine adjustment assembly 42 comprises a bolt 421 which is rotationally connected with the first fixed block 71, and a second sliding block 422 which is threadedly connected with the bolt 421; the second sliding block 422 is slidingly arranged on the sliding block 61, and the nail taking nozzle 2 is fixedly connected on the second sliding block 422; the bolt 421 is rotated to drive the second sliding block 422 to slide on the sliding block 61, so as to adjust the height of the nail taking nozzle 2 to adapt to different models of batteries and sealing nails.

[0035] The bolt 421 is threadedly connected with the second sliding block 422, and the thread connection can meet the need of fine adjustment of the height of the nail taking nozzle 2, and the bolt 421 has self-locking function along the axial direction, so as to avoid the change of the height difference between the nail taking nozzle 2 and the auxiliary member 3 in the process of repeated nail pressing.

[0036] More specifically, the end of the bolt 421 away from the nail taking nozzle 2 is connected with a rotating knob 425, and the rotating knob 425 is provided with anti-slip patterns, and the rotating knob 425 is arranged to facilitate the rotation of the bolt 421.

[0037] More specifically, the lifting drive 411 is a cylinder. The cylinder drives the sliding block 61 to slide on the fixed panel 5, and has a buffering function when the nail taking nozzle 2 and the auxiliary piece 3 are lowered to be attached to the battery. In the prior art, the buffer between the nail taking nozzle and the battery is a spring, which aims to avoid the impact between the nail taking nozzle and the battery. However, with the passage of time, the spring will have dust friction falling off, and the spring force will change or fail, thereby affecting the buffering effect. In the present embodiment, the cylinder is used instead of the spring, which ensures that the force between the auxiliary piece 3 and the battery will not cause damage to the battery due to excessive impact force, so that the nail taking nozzle 2 and the auxiliary piece 3 have a certain amount of floating.

[0038] More specifically, the cylinder is connected with a pressure regulating valve (not shown in the figure), which adjusts the output pressure of the cylinder, further ensuring that the force between the nail taking nozzle 2 and the auxiliary piece 3 and the battery will not cause damage to the battery due to excessive impact force.

[0039] More specifically, the sliding block 61 is fixedly connected with a second fixed block 72 below the first fixed block 71, and the auxiliary piece 3 is connected to the two sides of the second fixed block 72, respectively. A clearance groove 721 is provided on the second fixed block 72 between the two auxiliary pieces 3, and the nail taking nozzle 2 is arranged in the clearance groove 721.

[0040] More specifically, the fine adjustment assembly 42 further comprises a sliding groove 423 provided on the second sliding block 422, and a sliding limiting piece 424 is fixed in the sliding groove 423. The sliding limiting piece 424 is used to limit the maximum distance and the minimum distance of the fine adjustment of the nail taking nozzle 2. The bolt 421 is rotated to drive the sliding groove 423 to slide relative to the sliding limiting piece 424.

[0041] It can be understood that when the sliding limiting piece 424 abuts against the top of the sliding groove 423, the height difference between the nail taking nozzle 2 and the auxiliary piece 3 is the largest. When the sliding limiting piece 424 abuts against the bottom of the sliding groove 423, the height difference between the nail taking nozzle 2 and the auxiliary piece 3 is the smallest.

[0042] As an example, the sliding limiting piece 424 can be a screw, and the diameter of the screw nut is equal to the width of the sliding groove 423, so as to avoid the sliding groove 423 from falling off.

[0043] Further, the contact surface between the auxiliary piece 3 and the battery is a plane, which can reduce the probability of damage to the battery by the auxiliary piece 3 during the pre-pressing process, and is not easy to cause scratches or deformation on the surface of the battery.

[0044] Specifically, the contact surface between the auxiliary piece 3 and the battery is connected with the side wall of the auxiliary piece 3 in a rounded corner manner, further reducing the probability of scratching the surface of the battery.

[0045] The above is a specific description of the preferred embodiment of the present application, but the present application is not limited to the described embodiment, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application, and these equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
