AI Technical Summary
In the prior art, lithium batteries are prone to blockage of the vacuum equipment during transportation because they forget to remove the glue nails, and the air inside the battery cannot be extracted normally, resulting in the battery not meeting the production quality requirements.
A sealing glue nail is designed, including a glue nail body and an air conducting end. The glue nail body is used for insertion and removal and connection to the battery liquid injection port. An air conducting groove is opened on the side of the gas conducting end of the glue nail body to abut against the end side of the battery main body.
Even if the staff forget to remove the sealing spikes, the vacuum equipment can still extract external air through the air guide groove, triggering an alarm and prompting the removal of spikes in time, thereby ensuring that the air inside the battery is normally extracted and improving the battery quality pass rate.

Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of lithium batteries, and in particular to a sealing nail and a lithium battery. Background Art
[0002] Lithium battery is a secondary battery that relies on the movement of lithium ions between the positive and negative electrodes to achieve the purpose of charging and discharging. Lithium batteries are widely used in mobile phones, computers, digital cameras, electric vehicles, backup power supplies and other fields. The battery body of the lithium battery is composed of a cover plate and a shell. The cover plate is provided with an injection hole. The electrolyte is injected into the shell through the injection hole under pressure, and then the battery injection port is blocked with a rubber nail so that the injection hole is sealed by the rubber nail, thereby preventing leakage and air and moisture from entering the battery.
[0003] In the prior art, when the battery is transported in each process, it is necessary to use glue nails to block the battery filling port. The glue nails used are long-headed glue nails to prevent battery leakage and air and moisture from entering the battery. Before entering the formation cabinet, the glue nails need to be pulled out to facilitate the vacuum equipment to extract the air inside the battery. Figure 1 shown.
[0004] However, due to the large number of batteries entering the formation cabinet, the staff may easily forget to remove the plastic nails from the batteries, resulting in the vacuum nozzle of the vacuum equipment being blocked by the long-headed plastic nails during the vacuum operation, forming a sealed environment, so that the vacuum equipment can still perform normal vacuum operation, and the vacuum equipment will not issue an alarm to remind the staff due to the nozzle being blocked by the long-headed plastic nails, which in turn causes the vacuum equipment to be unable to extract the air inside the battery, resulting in the battery not meeting the production quality requirements. Utility Model Content
[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a sealing nail that enables the battery to meet the quality requirements of production.
[0006] The purpose of this disclosure is achieved through the following technical solutions:

[0009] An end of the air guide end portion which is away from the glue nail body is provided with an air guide groove.
[0010] In one embodiment, the air guide groove includes a first groove and a second groove, and the first groove is connected to the second groove.
[0011] In one embodiment, the air guide groove further includes a central connecting groove, and the first groove is connected with the second groove through the central connecting groove.
[0012] In one of the embodiments, the air guide groove is a cross air guide groove structure.
[0013] In one embodiment, the diameter of the air guide end is larger than that of the nail body.
[0014] In one of the embodiments, the sealing glue nail is an integrally formed structure.
[0015] In one of the embodiments, the sealing rubber nail is a flexible rubber piece.
[0016] A lithium battery comprises a battery body and a sealing nail as described in any one of the above embodiments, wherein the battery body is provided with a battery filling port, the nail body is plugged and connected to the battery filling port, and the side of the gas guide end facing away from the nail body abuts against the end side of the battery body.

[0019] Compared with the prior art, the present invention has at least the following advantages:
[0020] The plugging nail includes a nail body and an air guide end. The nail body is used to be plugged and connected to the battery filling port, and the end of the air guide end that is away from the nail body is provided with an air guide groove. When the lithium battery enters the formation cabinet, if the staff forgets to pull out the plugging nail from the lithium battery, the suction nozzle of the vacuum equipment will be blocked by the plugging nail during the vacuum operation. Since the air guide end of the plugging nail is provided with an air guide groove, the vacuum equipment will always extract the air outside the battery, and the vacuum equipment will not be able to extract to the preset vacuum value within the set time, thereby triggering the vacuum equipment alarm prompt, so that the staff can check the cause of the alarm, and then the staff will pull out the plugging nail from the lithium battery in time, so that the vacuum equipment can normally extract the air inside the lithium battery, so that the battery quality pass rate is higher.

When the lithium battery enters the formation cabinet, if the staff forgets to pull out the plugging nail from the lithium battery, the suction nozzle of the vacuum equipment will be blocked by the plugging nail during the vacuum operation. Since the air guide end of the plugging nail is provided with an air guide groove, the vacuum equipment will always extract the air outside the battery, and the vacuum equipment will not be able to extract to the preset vacuum value within the set time, thereby triggering the vacuum equipment alarm prompt, so that the staff can check the cause of the alarm, and then the staff will pull out the plugging nail from the lithium battery in time, so that the vacuum equipment can normally extract the air inside the lithium battery, so that the battery quality pass rate is higher.
[0032] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:
[0033] like Figures 2 to 3 As shown, a plugging nail 10 of an embodiment includes a nail body 100 and a gas guide end 200. The nail body 100 is used for plugging and unplugging and connecting to the battery liquid injection port 311. The gas guide end 200 is connected to one end side of the nail body 100. The side of the gas guide end 200 away from the nail body 100 is used to abut against the end side of the battery body 300. The end of the gas guide end 200 away from the nail body 100 is provided with a gas guide groove 210. In this embodiment, the nail body 100 is used for plugging and unplugging and connecting to the battery liquid injection port 311, so that the plugging nail 10 can seal the battery liquid injection port 311.
[0034] The above-mentioned plugging nail 10 includes a nail body 100 and an air guide end 200. The nail body 100 is used for plugging and unplugging and connecting to the battery liquid filling port 311. The end of the air guide end 200 that is away from the nail body 100 is provided with an air guide groove 210. When the lithium battery 20 enters the formation cabinet, if the staff forgets to pull out the plugging nail 10 from the lithium battery 20, the suction nozzle of the vacuum pumping device is blocked by the plugging nail 10 during the vacuum pumping operation. Since the air guide end 200 of the plugging nail 10 is provided with an air guide groove 210, the vacuum pumping device always extracts the air outside the battery, and then the vacuum pumping device cannot extract to the preset vacuum value within the set time, thereby triggering the vacuum pumping device alarm prompt, so that the staff can check the alarm cause, and then the staff can pull out the plugging nail 10 from the lithium battery 20 in time, so that the vacuum pumping device can normally extract the air inside the lithium battery 20, so that the battery quality pass rate is higher.
[0035] like Figure 2 As shown, in one embodiment, the air guide groove 210 includes a first groove 211 and a second groove 212, and the first groove 211 is connected to the second groove 212.

In this embodiment, the air guide groove 210 further includes a central connecting groove 213, and the first groove 211 is connected to the second groove 212 through the central connecting groove 213, so that the air guide effect of the air guide groove 210 is better.
[0037] like Figure 1 to Figure 2 As shown, in one embodiment, the air guide groove 210 is a cross air guide groove structure. In this embodiment, the air guide groove 210 is a cross air guide groove structure, so that the air guide groove 210 has a better air guide effect.
[0038] like Figure 2 As shown, in one embodiment, the diameter of the gas guide end 200 is larger than the glue nail body 100. In this embodiment, the diameter of the gas guide end 200 is larger than the glue nail body 100, so that the gas guide end 200 will not enter the battery filling port 311.
[0039] like Figure 2As shown, in one embodiment, the plugging glue nail 10 is an integrally formed structure. In this embodiment, the integrally formed structure makes the plugging glue nail 10 more compact and more stable. It can be understood that in other embodiments, the plugging glue nail 10 is not limited to an integrally formed structure. For example, the glue nail body 100 and the air guide end 200 are formed separately and fixed together by gluing.
[0040] like Figure 2 As shown, in one embodiment, the sealing rubber nail 10 is a flexible rubber piece, so that the sealing rubber nail 10 has good flexibility, so that the rubber nail body 100 can be better plugged and unplugged to be connected to the battery filling port 311.
