[0025] It should be noted that the soft-pack battery ear tab perforation tool described in the present utility model is used for but not limited to battery pack production, etc. For the convenience of description, in the present utility model, only the case where the soft-pack battery ear tab perforation tool is applied to battery pack production is taken as an example for description, and the principle of the soft-pack battery ear tab perforation tool applied to other types of equipment is substantially the same as that applied to battery pack production, and will not be elaborated here one by one.

[0026] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of the soft-pack battery ear tab perforation tool in an embodiment of the present utility model. The soft-pack battery ear tab perforation tool includes a base 100 and a guiding assembly 200. The base 100 is used to place the soft-pack battery. The guiding assembly 200 includes a plurality of guiding rods 210 and positioning members 220 that correspond to each other one by one. The plurality of guiding rods 210 are arranged side by side on the base 100, and the guiding rods 210 are used to support the ear tab. The positioning members 220 are installed on the guiding rods 210, and it has a first state of fixing the ear tab to the guiding rod 210 and a second state of separating the ear tab from the guiding rod 210.

[0027] In this embodiment, first, the soft-pack battery is placed on the base 100, and each ear tab of the soft-pack battery is placed on the guiding rod 210 one by one. Subsequently, the positioning member 220 is adjusted to the first state, so that the ear tab can be fixed on the guiding rod 210. The guiding rod 210 together with the ear tab is made to pass through the ear-piercing hole of the circuit board. Subsequently, the positioning member 220 is adjusted to the second state, so that the ear tab is separated from the guiding rod 210. At this time, the guiding rod 210 is pulled out from the ear-piercing hole, and the ear tab still passes through the ear-piercing hole. Using the above soft-pack battery ear tab perforation tool, a plurality of soft-textured ear tabs can be quickly inserted into a plurality of ear-piercing holes one by one, thus accelerating the working efficiency of ear tab perforation.

[0028] In some of the embodiments, the positioning member 220 is installed at the end of the guiding rod 210 away from the base 100, and when the positioning member 220 is in the first state, the positioning member 220 fixes the end of the ear tab at the end of the guiding rod 210 away from the base 100.

[0029] In this embodiment, the positioning member 220 is located at the end of the guide rod 210 away from the base 100, so that the end of the tab is fixed to the end of the guide rod 210 away from the base 100, so that the tab can be tensioned to facilitate subsequent tab perforation operations.

[0030] On the basis of the above embodiments, in some of the embodiments, the guide rod 210 includes a base rod 211, a sliding rod 212 and an elastic part 213, the base rod 211 is connected to the base 100, the sliding rod 212 is slidably arranged on the base rod 211, one end of the elastic part 213 is connected to the base rod 211, and the other end thereof is connected to the sliding rod 212, and the elastic part 213 has an elastic force that makes the sliding rod 212 move away from the base 100, and the positioning member 220 is installed on the sliding rod 212.

[0031] In this embodiment, before the positioning member 220 fixes the pole ear, the elastic force of the elastic portion 213 can be overcome to push the slide rod 212 in a direction close to the base 100. At this time, the positioning member 220 is used to fix the end of the pole ear on the end of the guide rod 210 away from the base 100. Then the elastic portion 213 releases the elastic potential energy, thereby pushing the slide rod 212 to slide in a direction away from the base 100, so that the pole ear is fully tensioned.

[0032] In some embodiments, the base rod 211 defines a slide groove 2111 , and the slide rod 212 is slidably embedded in the slide groove 2111 .

[0033] In this embodiment, the base rod 211 slides along the sliding groove 2111 , so that the base rod 211 has a precise sliding track.

[0034] Any specific implementation of the elastic part 213 that can meet the above requirements is feasible. In some embodiments, the elastic part 213 includes a spring 2131, which is built into the slide groove 2111, and the two ends of the spring 2131 are respectively connected to the base rod 211 and the slide rod 212.

[0035] In this embodiment, when the slide bar 212 moves toward the direction close to the base 100 , the spring 2131 is compressed to store elastic potential energy. When the slide bar 212 moves toward the direction close to the base 100 , the spring 2131 releases the elastic potential energy.

[0036] In some embodiments, a guide groove 2121 for receiving the tab is formed on the slide bar 212 .

[0037] In this embodiment, the guide groove 2121 can guide the electrode tab, so that the electrode tab with a soft texture can be placed regularly in the guide groove 2121.

[0038] In some embodiments, the base 100 has a plurality of mounting positions 110 arranged side by side, and the base rod 211 is detachably mounted on any one of the mounting positions 110.

[0039] In this embodiment, the number of the mounting positions 110 is more than the number of the base rods 211. Adjusting the mounting positions 110 of the base rods 211 can adjust the spacing between the respective base rods 211, so that the base rods 211 with different spacings can be adapted to battery packs with different ear spacings.

[0040] As long as the implementation manner of the positioning member 220 that can fix the ear to the end of the sliding rod 212 is feasible. In some of these embodiments, the end of the sliding rod 212 has a magnetic attraction portion 2122, the positioning member 220 includes a magnetic attraction buckle 221, the magnetic attraction buckle 221 has a magnetic force that attracts the magnetic attraction portion 2122, when the positioning member 220 is in the first state, the magnetic attraction buckle 221 and the magnetic attraction portion 2122 clamp the ear, and when the positioning member 220 is in the second state, the magnetic attraction buckle 221 is away from the magnetic attraction portion 2122.

[0041] In this embodiment, when the magnetic attraction buckle 221 and the magnetic attraction portion 2122 approach each other, the magnetic attraction buckle 221 and the magnetic attraction portion 2122 will clamp the ear so as to fix the ear to the end of the sliding rod 212.

[0042] In some of these embodiments, the base 100 is provided with a storage groove 120 for placing a soft-pack battery.

[0043] In this embodiment, the soft-pack battery is placed in the storage groove 120, and the inner wall of the storage groove 120 is attached to the outer wall of the soft-pack battery, so as to limit the soft-pack battery by using the storage groove 120.

[0044] In some of these embodiments, the guide rod 210 is an insulating guide rod 210.

[0045] In this embodiment, since the guide rod 210 is made of an insulating material, it can effectively prevent the soft-pack battery from accidentally breaking the circuit.

[0046] For a better understanding of the present utility model, the following is combined with Figures 1 to 2 to describe the technical solution of the present utility model in detail:

[0047] First, place the soft-pack battery in the storage groove 120. Before placing the tab, the sliding rod 212 can be pushed towards the base 100 against the elastic force of the elastic part 213. Subsequently, place the tab in the guiding groove 2121. At this time, the tab is clamped by the magnetic snap 221 and the magnetic part 2122, so that the tab is fixed at the end of the sliding rod 212. Then the elastic part 213 releases the elastic potential energy, which can push the sliding rod 212 to slide away from the base 100, making the tab fully tensioned. Let the guiding rod 210 and the tab pass through the tab-piercing hole of the circuit board together. Move the magnetic snap 221 away from the magnetic part 2122, so that the tab is separated from the guiding rod 210. At this time, pull out the guiding rod 210 from the tab-piercing hole, and keep the tab still passing through the tab-piercing hole. Using the above-mentioned soft-pack battery tab-piercing tool, multiple soft tabs can be quickly and correspondingly passed through multiple tab-piercing holes one by one, thus improving the working efficiency of tab piercing.
