[0002] Shallow puncture tooling is mainly used to simulate puncture of batteries to test their safety performance. With the rapid development and widespread application of battery technology, the standards and requirements for battery safety testing are constantly improving, which also poses more stringent challenges to shallow puncture tooling. Most of the shallow puncture tooling on the market currently uses a double-rod limiter resistance balance solution to fix the battery, ensure the stability of the battery position after puncture, and avoid displacement of the battery when the needle is removed. However, the double-rod limiter method has poor adaptability to battery size. When applied to small batteries, due to limited adjustment space, the battery is prone to fall off or dislocation during the needle collection stage, which can cause battery damage. At the same time, the double-rod limiter method cannot fully consider the expansion effect caused by the generation of internal gas in the battery during the puncture process, which will increase the complexity and uncertainty of the test.

[0025] The utility model provides a shallow piercing tool according to the first embodiment. Figure 1 to Figure 2 As shown, Figure 1 This is a schematic diagram of the structure of a shallow piercing tool provided by an embodiment of the utility model. Figure 2 It is a structural schematic diagram of a battery 7 in a shallow puncture tool provided by an embodiment of the utility model. A shallow puncture tool provided by an embodiment of the utility model comprises a front limit plate 1, a clamping plate 2, a clamping component and a puncture head 4. The front limit plate 1 has a plurality of avoidance holes, the clamping plate 2 has a limit groove 21, the clamping component is connected to the front limit plate 1 and the clamping plate 2 respectively, and a clamping space 31 for placing the battery 7 is provided between the front limit plate 1 and the clamping plate 2. The puncture head 4 penetrates the limit groove 21 and then punctures the battery 7, and the avoidance hole is opposite to the limit groove 21, so that the puncture head 4 punctures the avoidance hole.

[0026] There is a space for placing the battery 7 inside the clamping space 31 between the front limit plate 1 and the clamping plate 2. There are multiple avoidance holes on the front limit plate 1, and the avoidance holes are opposite to the limit groove 21. After the acupuncture head 4 penetrates the limit groove 21 and pierces the inside of the battery 7, it will be inserted into the avoidance hole to prevent the front limit plate 1 from blocking the acupuncture head 4. The front limit plate 1 and the clamping plate 2 can be connected to each other by the clamping component, and the clamping force of the clamping component can be adjusted as needed to meet the clamping requirements of batteries 7 of different sizes.

[0027] In this embodiment, by connecting the clamping parts to the front limit plate 1 and the clamping plate 2 respectively, a clamping space 31 for placing the battery 7 is provided between the front limit plate 1 and the clamping plate 2, a plurality of avoidance holes are provided on the front limit plate 1, and a limit groove 21 is provided on the clamping plate 2. After the acupuncture head 4 penetrates the limit groove 21, it can penetrate the battery 7, and the avoidance hole is opposite to the limit groove 21, so that the acupuncture head 4 penetrates the avoidance hole. In this way, the spacing between the front limit plate 1 and the clamping plate 2 can be adjusted by the clamping parts to adapt to batteries 7 of different sizes. When the battery 7 is placed in the clamping space 31, the clamping parts can apply appropriate pressure to fix the battery 7 firmly in the tooling. At the same time, after the acupuncture head 4 penetrates the limit groove 21 and penetrates the inside of the battery 7, the avoidance hole and the limit groove 21 are opposite to each other, so that the acupuncture head 4 can smoothly penetrate the front limit plate 1 without hindrance, and then the battery 7 can be stably fixed, adapting to batteries 7 of different sizes, which is conducive to improving applicability and flexibility. Thereby achieving a technical effect of improving applicability and flexibility.

[0028] As an embodiment, the shallow piercing tool further includes a rear limit plate 5 and a plurality of avoidance limit blocks 6, and the avoidance limit blocks 6 are respectively connected to the rear limit plate 5 and the front limit plate 1. The rear limit plate 5 is arranged opposite to the front limit plate 1, and the rear limit plate 5 can be fixedly mounted on the equipment, and support is provided by the rear limit plate 5.

[0029] In some embodiments, the avoidance hole is a through hole structure formed on the front limit plate 1, and the diameter of the through hole is larger than the diameter of the acupuncture head 4, that is, the avoidance hole is circular, and the acupuncture head 4 is also circular, and the diameter of the acupuncture head 4 is smaller than the diameter of the avoidance hole, so that the acupuncture head 4 can smoothly pass through the avoidance hole without generating additional resistance after penetrating the limit groove 21 and piercing the battery 7. At the same time, since the diameter of the avoidance hole is large, it can ensure that the acupuncture head 4 penetrates smoothly.

[0030] In some embodiments, the limiting groove 21 includes a first through groove 211 and a second through groove 212, and the first through groove 211 and the second through groove 212 are cross-distributed, so that when the acupuncture head 4 pierces the battery 7, it can enter the battery 7 through different through groove paths, thereby increasing the flexibility of the tooling.

[0031] In some embodiments, the first through slot 211 is located on the battery 7 in the direction of the clamping plate 2 approaching the battery 7 and the second through slot 212 is located on the battery 7 in the direction of the clamping plate 2 approaching the battery 7 and the battery 7. This ensures that the acupuncture head 4 can accurately pass through the through slot and enter the battery 7 when piercing the battery 7, while avoiding the situation that the battery 7 is damaged or the tooling fails due to the improper position of the through slot.

[0032] In some embodiments, the limiting groove 21 is a cross-shaped structure, that is, the first through groove 211 and the second through groove 212 are perpendicular to each other, so that the acupuncture head 4 can enter the battery 7 through the through grooves in four directions when piercing the battery 7, further increasing the flexibility of the tooling. At the same time, it will make the acupuncture head 4 pass through the through groove more smoothly, which is conducive to reducing resistance.

[0033] In some embodiments, the front limit plate 1 is provided with a first threaded hole 12, the clamping plate 2 is provided with a second threaded hole 213, the clamping member is threadedly connected to the first threaded hole 12 and the second threaded hole 213 respectively, and the length of the clamping member is greater than the distance between the front limit plate 1 and the clamping plate 2. By providing the first threaded hole 12 on the front limit plate 1 and the second threaded hole 213 on the clamping plate 2. The clamping members are threadedly connected to these threaded holes respectively, and the distance between the front limit plate 1 and the clamping plate 2 is adjusted by rotating the clamping member to accommodate batteries 7 of different sizes. Since the length of the clamping member is greater than the distance between the front limit plate 1 and the clamping plate 2, when the clamping member is rotated, it can be ensured that the distance between the front limit plate 1 and the clamping plate 2 is accurately adjusted, and sufficient pressure can be applied to firmly fix the battery 7. When the battery 7 is placed in the clamping space 31 surrounded by the front limit plate 1 and the clamping plate 2, by rotating the clamping member, appropriate pressure can be applied to firmly fix the battery 7 in the tooling.

[0034] In some embodiments, the clamping component includes a first clamping screw 32 and a second clamping screw 33, and the first clamping screw 32 and the second clamping screw 33 can both refer to threaded rods, the first clamping screw 32 is connected to the front limit plate 1 and the clamping plate 2, respectively, the second clamping screw 33 is connected to the front limit plate 1 and the clamping plate 2, respectively, the limiting groove 21 is located between the first clamping screw 32 and the second clamping screw 33, and the front limit plate 1, the clamping plate 2, the first clamping screw 32 and the second clamping screw 33 enclose the clamping space 31. The clamping component includes a first clamping screw 32 and a second clamping screw 33, and is connected to the front limit plate 1 and the clamping plate 2, respectively. The limiting groove 21 is located between the first clamping screw 32 and the second clamping screw 33, and the front limit plate 1, the clamping plate 2, the first clamping screw 32 and the second clamping screw 33 together enclose the clamping space 31. The number of the first clamping screw 32 and the second clamping screw 33 can both be three, and the three first clamping screws 32 are evenly spaced, and the three second clamping screws 33 are also evenly spaced, and the first clamping screw 32 and the second clamping screw 33 can be adjusted separately to ensure that the battery 7 is evenly fixed in the tooling. In addition, the double clamping of the first clamping screw 32 and the second clamping screw 33 not only provides a balanced clamping force for the battery 7, but also ensures the stability of the acupuncture process. Even when the battery 7 expands due to acupuncture, the optimal clamping state can be maintained by properly adjusting the screws, effectively preventing the battery 7 from shifting or being damaged during the test.

[0035] In some embodiments, the front limit plate 1 includes a first limit surface 13 and a second limit surface 14, and the avoidance hole passes through the first limit surface 13 and the second limit surface 14; the clamping plate 2 includes a first clamping surface 214 and a second clamping surface 215, and the limit groove 21 passes through the first clamping surface 214 and the second clamping surface 215. The first limit surface 13 and the first clamping surface 214 are parallel to each other, and the clamping parts are perpendicular to the first clamping surface 214 and the second clamping surface 215, respectively, so that the spacing between the front limit plate 1 and the clamping plate 2 can be accurately adjusted by the clamping parts, and the uniform distribution of the clamping action is also ensured to avoid local stress concentration, so that the battery 7 is subjected to uniform and appropriate pressure during the puncture test. At the same time, since the avoidance hole and the limit groove 21 pass through the two surfaces of the front limit plate 1 and the clamping plate 2 respectively, it can be ensured that the puncture head 4 can smoothly penetrate the front limit plate 1 without obstruction when piercing the battery 7, which is conducive to improving the stability and safety of the tooling, and also makes the tooling easier to manufacture and install.

[0036] In order to explain in detail a shallow puncture device provided by the present invention, the above-mentioned embodiment 1 explains in detail a shallow puncture tool. Based on the same inventive concept, the present application also provides a shallow puncture device, see embodiment 2 for details.

[0037] The second embodiment of the present utility model provides a shallow puncture device, and the shallow puncture device is provided with the shallow puncture tooling.

After the acupuncture head 4 penetrates the limit groove 21, the battery 7 can be penetrated, and the avoidance hole is opposite to the limit groove 21, so that the acupuncture head 4 penetrates the avoidance hole. In this way, the spacing between the front limit plate 1 and the clamping plate 2 can be adjusted by the clamping parts to adapt to batteries 7 of different sizes. When the battery 7 is placed in the clamping space 31, the clamping parts can apply appropriate pressure to fix the battery 7 firmly in the tooling. At the same time, after the acupuncture head 4 penetrates the limit groove 21 and penetrates the inside of the battery 7, the avoidance hole and the limit groove 21 are opposite to each other, so that the acupuncture head 4 can smoothly penetrate the front limit plate 1 without being hindered, and then the battery 7 can be stably fixed, adapting to batteries 7 of different sizes, which is conducive to improving applicability and flexibility.
