Description

Technical Field

[0001] This utility model relates to the field of packaging tearing technology. More specifically, this utility model relates to a button lithium battery packaging performance testing system. Background Technology

[0002] While button battery packaging may seem simple, sophisticated packaging involves more than just marketing; it encompasses various elements that inform consumers about the product's contents, brand, and brand name, while also considering structural innovation and visual appeal. Attractive packaging can entice young children to play with or accidentally swallow button lithium batteries. If the packaging is substandard, children can easily tear it open and swallow the battery. If the battery becomes lodged in the esophagus, its voltage exceeding 2V can cause water electrolysis and the formation of hydroxide ions. These hydride ions form a strong alkaline solution, which can lead to chemical burns, soft tissue perforation, and in severe cases, death. Therefore, safe and compliant button lithium battery packaging is of paramount importance.

Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0032] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0033] It should be noted that in the description of this utility model, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] like Figures 1-4 This utility model provides a button lithium battery packaging performance testing system, comprising:

[0035] The first bending test device 1 includes a base 100, and a first clamping member 110 and a second clamping member 120 disposed on the base 100.

[0036] The first clamping member 110 and the second clamping member 120 are disposed opposite to each other. The first clamping member 110 includes a first clamping plate 111 and a first operating handle 112 rotatably connected thereto. The second clamping member 120 includes a second clamping plate 121 and a second operating handle 122 rotatably connected thereto. The first clamping plate 111 and the second clamping plate 121 rotate 0 to 90 degrees respectively under the rotation drive of the first operating handle 112 and the second operating handle 122.

[0037] In the above technical solution, firstly, the base 100 is made of high-strength aluminum alloy, and its bottom is equipped with a rubber anti-slip pad to ensure that the entire device can be stably placed on the workbench during the test and will not easily move due to operation. The upper surface of the base 100 is finely polished to provide a flat reference surface for the subsequent installation of the first clamping component 110 and the second clamping component 120. The first clamping plate 111 is made of stainless steel plate with moderate hardness and fine texture on the surface. The fine texture design can increase the friction between the plate and the button lithium battery package 5, preventing the button lithium battery package 5 from slipping during the torsion test. The first clamping plate 111 is rotatably connected to the first operating handle 112 by a pin. The pin is made of high-precision alloy steel to ensure smooth and stable rotation. The first operating handle 112 is designed with an ergonomic arc shape, which is convenient for the operator to grip and apply force. Its length is moderate, so that the operator can easily apply sufficient torque when rotating. A rubber anti-slip sleeve can also be fitted to the end of the first operating handle 112 to further improve the stability of the grip. Similarly, the second clamping plate 121 of the second clamping member 120 is also made of stainless steel plate of the same specifications as the first clamping plate 111 to ensure the balance of clamping the two sides of the button lithium battery package 5. The connection method between the second operating handle 122 and the second clamping plate 121, as well as its own design features, are consistent with the first operating handle 112 to ensure the symmetry of the entire testing process.

[0038] The first bending test device 1 is used to simulate a human hand test (holding one side of the button lithium battery package with the fingers of one hand and the other side with the other hand, twisting the button lithium battery package diagonally in opposite directions at a twist angle of 45°±5°, twisting three times in both directions). The first clamping plate 111 clamps one side of the button lithium battery package 5, and the second clamping plate 121 clamps the other side of the button lithium battery package 5 to test its torsional performance. When conducting the torsional performance test, the operator first places the button lithium battery package 5 horizontally, aligning one side of the package with the first clamping plate 111 and the other side with the second clamping plate 121, and clamps them tightly. The operator then holds the first operating handle 112 and the second operating handle 122 with both hands, and slowly and evenly rotates the two operating handles in opposite directions according to a predetermined test standard. During the rotation process, the first clamping plate 111 and the second clamping plate 121 rotate synchronously from 0 to 90 degrees with the rotation of the operating handle, thereby applying a torsional force to the button lithium battery package 5, simulating the torsion that it may be subjected to during actual use or transportation, and evaluating whether its torsional performance meets the requirements by observing the deformation, damage and other conditions of the button lithium battery package 5 during the torsion process.

[0039] In another technical solution, the button lithium battery packaging performance testing system further includes:

[0040] The second bending test device 2 includes a base 200 and a ramp 210 fixed at a 150-degree angle to the base 200.

[0041] In the aforementioned technical solution, the base 200 is cast from heavy-duty stainless steel, with a large flat bottom design to ensure a very low center of gravity when the entire device is placed on the experimental table, making it less prone to tipping over. At each of the four corners of the base 200, a rubber shock-absorbing pad is embedded. This further enhances the friction between the device and the tabletop, preventing displacement due to accidental collisions during testing. Furthermore, the shock-absorbing pads absorb some of the vibrations generated during operation, reducing the impact on testing accuracy. The ramp 210, like the base 200, is cast from high-strength stainless steel. This material provides sufficient rigidity to support the button lithium battery package 5 while preventing scratches and damage during testing. The ramp 210 and base 200 are fixedly connected using specially designed high-strength hexagonal screws. The hexagonal screws pass through pre-drilled mounting holes on the bottom of the ramp 210 and are screwed into threaded holes in the base 200, ensuring a tight connection and maintaining a precise 150-degree angle. The surface of the ramp 210 is specially frosted to form a fine and uniform texture. This texture can increase the friction between the coin lithium battery package 5 and the coin lithium battery package 5 to prevent the coin lithium battery package 5 from sliding on the ramp, and will not prevent the coin lithium battery package 5 from bending and deforming according to the test requirements.

[0042] The second bending test device 2 is used to simulate a human hand test (holding the button lithium battery package 5 with the fingers of one hand and the battery with the fingers of the other hand. Bending the button lithium battery package 5 close to the battery until one hand touches the other). When conducting the bending performance test of the button lithium battery package 5, the operator first carefully places the button lithium battery package 5 to be tested on the ramp 210, ensuring that the long axis of the button lithium battery package 5 is basically consistent with the inclination direction of the ramp, and that the connection points between adjacent lithium batteries are precisely aligned with the bending start position of the ramp 210. After placement, the operator uses their fingers to press down, gradually bending the package between adjacent lithium batteries at the ramp 210. During the bending process, the operator must constantly monitor the bending state of the button lithium battery package 5, observing for any abnormalities such as cracked battery casings, exposed internal cells, or broken connection points. These phenomena are used to comprehensively evaluate whether the bending performance of the button lithium battery package 5 meets the requirements.

[0043] In another technical solution, the button lithium battery packaging performance testing system further includes:

[0044] The tear testing device 3 includes a support base 300, a first fixed member 310, a first movable member 320, and a tubular force gauge 330;

[0045] The first fixing member 310 is fixed to one end of the support base 300. A third clamping plate 340 is provided on the first fixing member 310. The lower end of the first movable member 320 is provided with a first clamping groove 350 and the side is provided with a first pull ring 370. The tubular force gauge 330 is supported on the upper part of the support base 300 by a support column along the length direction of the support base 300. One end of the tubular force gauge 330 is connected to the first pull ring 370 through a first hook 360, and the other end is connected to the third operating handle 380.

[0046] In the above technical solution, the support base 300 is made of high-quality carbon steel through precision machining. Its shape is rectangular, and rubber anti-slip pads are installed at the four corners of the bottom. These pads not only increase friction with the tabletop, making the device more stable, but also provide cushioning and shock absorption, reducing interference from external vibrations during testing. The first fixing component 310 is forged from stainless steel and machined. It is tightly fixed to one end of the support base 300 with four high-strength internal hexagonal screws, ensuring the reliability and stability of the connection. The third clamping plate 340 is made of alloy steel, with a surface hardened to improve hardness. Its clamping surface is finely ground to form a cross-shaped diamond pattern. This pattern design greatly enhances the clamping friction, effectively preventing the button lithium battery package 5 from slipping off during testing. The main frame of the first movable component 320 is made of aluminum alloy. Utilizing the low density and high strength of aluminum alloy, the overall weight is reduced for ease of operation while meeting the structural strength requirements of the test. The first clamping groove 350 is located at the lower end of the first movable member 320. It is inlaid with a layer of specially made polyurethane elastomer. This material has high elasticity and a high coefficient of friction, which gently wraps around the button lithium battery package 5 to prevent pinching and ensures that the button lithium battery package 5 does not shift under tension. The first pull ring 370 is located on the side of the first movable member 320. The first pull ring 370 is made of thickened stainless steel and polished to ensure smooth connection with the first hook 360 and avoid jamming that could affect the accuracy of force transmission. The tubular force gauge 330 is a high-precision, high-sensitivity electronic tubular force gauge with a measurement range accurately covering the 0–50 N range, meeting the requirements for 25 N tensile force testing with a measurement accuracy of up to 0.1 N. The outer shell of the tubular force gauge 330 is made of insulating and impact-resistant engineering plastic, effectively protecting the internal precision sensing elements. The support column is made of carbon fiber, possessing an extremely high strength-to-weight ratio, firmly supporting the tubular force gauge 330 on the support base 300, ensuring the force gauge remains horizontally stable throughout the test. The first hook 360 at one end of the force gauge is made of stainless steel, while the other end, which connects to the third operating handle 380, is designed in an ergonomic arc shape. The handle surface is covered with a layer of soft silicone, allowing for comfortable and stable gripping and force application by the operator. The connection between the tubular force gauge 330 and the third operating handle 380 can be achieved by pre-molding a threaded connecting sleeve at one end of the tubular force gauge 330's outer shell. The sleeve material is the same as the engineering plastic of the outer shell to ensure consistent thermal expansion coefficients and prevent loosening due to temperature changes. The inner diameter of the connecting sleeve is slightly larger than the outer diameter of the insertion end of the third operating handle 380, with a 0.5–1 mm gap between them to accommodate possible assembly errors. The surface of the insertion end of the third operating handle 380 is machined with a ring-shaped groove, the groove depth is about 2 to 3 mm, and the width is between 3 and 4 mm.During connection, first, a high-strength rubber O-ring is embedded in the annular groove. The O-ring is made of wear-resistant, highly elastic nitrile rubber with a Shore hardness between 60 and 70, ensuring both good sealing and cushioning while providing sufficient friction to prevent the third operating handle 380 from rotating within the sleeve. Next, the insertion end of the third operating handle 380 with the O-ring is slowly inserted into the connecting sleeve of the tubular force gauge 330 housing until the base of the handle is flush with the end face of the sleeve. Then, a specially designed stainless steel set screw with a Phillips head for easy screwdriver operation is screwed into the pre-drilled threaded hole on the side of the connecting sleeve until the screw tip firmly presses against the insertion end of the third operating handle 380, further securing the handle and preventing axial movement. By combining the rubber O-ring sealing and buffering with the set screw fixing, the connection between the housing of the tubular force gauge 330 and the third operating handle 380 is ensured to be stable and reliable, while maintaining a good feel during operation and preventing the accuracy of the tensile test from being affected by loose connection.

[0047] The tear test device 3 is used to simulate a human hand test (attempting to tear the button lithium battery packaging with a force of at least 25 N). When conducting the tear performance test on the button lithium battery packaging 5, the operator first carefully places one side of the button lithium battery packaging 5 into the first clamping groove 350, ensuring a tight fit between the button lithium battery packaging 5 and the polyurethane elastomer. Then, the other side is aligned with the third clamping plate 340 and fixed thereto. Next, the operator holds the third operating handle 380, watching the display screen of the tubular force gauge 330, and slowly and uniformly pulls outward, gradually increasing the pulling force from zero until the force gauge displays a pulling force of 25 N. During this process, the operator must closely monitor the changes in the button lithium battery packaging 5 at the stressed areas, carefully observing for any abnormalities such as tearing, delamination, or exposed battery cells. Based on these phenomena, the tear performance of the button lithium battery packaging 5 is accurately assessed to determine if it is up to standard.

[0048] In another technical solution, the button lithium battery packaging performance testing system further includes:

[0049] The push-test device 4 includes a support platform 400, a second fixed component 410, a second movable component 420, and a weight 430.

[0050] The second fixing member 410 is fixed to the support platform 400 in an inverted L-shape. A fourth clamping plate 440 is fixed to the second fixing member 420. The second movable member 420 has a second clamping groove 450 on one side and a second pull ring 460 at its lower end. The weight 430 has a second hook 470, which can be hung on the second pull ring 460. One side of the button lithium battery package 5 is in the second clamping groove 450, and the other side is clamped to the fourth clamping plate 440. The pushing performance of the button lithium battery package 5 is tested by pulling it downward with the weight 430.

[0051] In the aforementioned technical solution, the support platform 400 is made of high-strength aerospace-grade aluminum alloy, precision-milled and anodized to ensure excellent structural strength and corrosion resistance, adapting to various testing environments. Adjustable rubber feet are installed at the four corners of the support platform 400's bottom. Rotating these feet allows for precise adjustment of the platform's level to meet high-precision testing requirements. Simultaneously, the rubber material of the feet effectively absorbs vibrations during testing, preventing external interference from affecting the test results. The second fixing component 410 is made of forged alloy steel, featuring a stable inverted L-shaped structure. It is tightly fixed to the support platform 400 using high-strength internal hexagonal bolts. The bolt tightening torque is rigorously calibrated to ensure the connection is rock-solid and will not experience any displacement or deformation under the powerful force of the pressing test. The fourth clamping plate 440 is made of hardened alloy steel, and its surface has undergone fine electrical discharge machining to form a dense and appropriately deep mesh pattern, which greatly enhances the friction with the button lithium battery package 5, ensuring that one side of the button lithium battery package 5 can be firmly clamped during the test and will not loosen. The main frame of the second movable component 420 is made of alloy steel, and the second clamping groove 450 is located on one side. The inside is lined with a layer of special fluororubber soft pad. Fluororubber has excellent high temperature resistance and chemical corrosion resistance, and can protect the button lithium battery package 5 from being pinched even under some special environmental tests. The micro-protrusion design on the soft pad further enhances the clamping stability and prevents the button lithium battery package 5 from slipping during the pushing process. The second pull ring 460 is located at the lower end. It is made of high-strength stainless steel and polished to a mirror-like surface, ensuring that the second hook 470 of the weight 430 can be smoothly hooked in. After hooking in, the second pull ring 460 can rotate flexibly to ensure that the pushing force is applied vertically downward and avoids unnecessary lateral force interference with the test. Weight 430 is made of high-precision CNC machined stainless steel, with quality errors controlled within a very small range. Its surface is mirror-polished and rust-proofed, making it both aesthetically pleasing and durable. The second hook 470 is integrally molded with weight 430. The second hook 470 undergoes enhanced heat treatment, giving it greater load-bearing capacity. The opening size of the second hook 470 is just right, slightly larger than the outer diameter of the second pull ring 460, facilitating quick and easy hooking and unhooking, while also ensuring extremely high stability after installation.

[0052] The push-pressure testing device 4 is used to simulate a human hand test (pushing the button lithium battery out of the packaging with fingers) or a pull with a mass of at least 5 kg for 30 seconds. When conducting the push-pressure performance test on the button lithium battery packaging 5, the operator first carefully places one side of the button lithium battery packaging 5 into the second clamping groove 450, ensuring a tight fit between the battery packaging and the fluororubber pad. Then, the other side is aligned with the fourth clamping plate 440 and fixed thereto. Next, according to the test plan, a weight 430 of appropriate mass is precisely selected, and the second hook 470 of the weight 430 is securely attached to the second pull ring 460. The weight is then slowly released, allowing it to smoothly pull the second movable component 420 downwards under gravity, thereby applying precise downward pushing pressure to the button lithium battery packaging 5. During this process, the operator pays close attention to the changes in the state of the battery pack under pressure, including whether the outer shell is dented or wrinkled, and whether the internal cells are deformed or displaced by pressure, so as to comprehensively judge whether the pushing performance of the button lithium battery pack 5 meets the standard.

[0053] In another technical solution, the base 100 is provided with a first sliding groove 101 and a second sliding groove 102 corresponding to the positions of the first clamping member 110 and the second clamping member 120, respectively. The first clamping member 110 can slide in the first sliding groove 101 along the length direction of the base 100, and the second clamping member 120 can slide in the second sliding groove 102 along the length direction of the base 100 to adjust the position between the first clamping member 110 and the second clamping member 120 according to the button lithium battery package 5.

[0054] In the above technical solution, a first sliding groove 101 and a second sliding groove 102 are machined on the base 100 at positions corresponding to the first clamping member 110 and the second clamping member 120 using a precision milling process. The cross-sectional shape of the first sliding groove 101 and the second sliding groove 102 is designed as a "T" shape. This shape ensures stable sliding of the clamping member within the groove and effectively prevents it from dislodging. The inner wall of the sliding groove is finely polished and coated with a layer of molybdenum disulfide grease, which greatly reduces the friction during sliding of the clamping member, allowing for smooth movement. At the bottom of the first clamping member 110, corresponding to the position of the first sliding groove 101, a specially designed "T"-shaped slider is installed. The slider is welded to the main body of the first clamping member 110 to ensure connection strength. The slider is made of wear-resistant nylon material, ensuring a certain degree of hardness while avoiding scratches caused by direct friction with the metal surface of the sliding groove. The operator can manually push the first clamping member 110 according to the size of the button lithium battery package 5, so that it can slide smoothly along the length of the base 100 along the first slide groove 101 and easily adjust its position. Similarly, the "T"-shaped slider at the bottom of the second clamping member 120 is adapted to the second slide groove 102, and its material and connection method are the same as those of the first clamping member 110.

[0055] When preparing for the test of the button lithium battery package 5, the operator first observes the size of the button lithium battery package 5, and then slides the first clamping member 110 and the second clamping member 120 respectively, so that the distance between them is just enough to accommodate the battery package, and ensures that the first clamping plate 111 and the second clamping plate 121 can accurately clamp the two sides of the battery package. The subsequent torsion test operation procedure is the same as before, that is, by rotating the first operating handle 112 and the second operating handle 122, the clamping plate is driven to rotate 0 to 90 degrees to perform a torsion performance test on the button lithium battery package 5. During this process, since the position of the clamping member can be flexibly adjusted, it can adapt to battery packages of different specifications, which greatly improves the versatility of the testing device.

[0056] In another technical solution, the weight is no less than 5 kg. A weight of sufficient weight can more accurately simulate harsh usage scenarios and effectively test the pressure resistance of the battery packaging.

[0057] In another technical solution, when the first clamping member 110 and the second clamping member 120 slide to predetermined positions on the first slide groove 101 and the second slide groove 102 respectively, the first clamping member 110 and the second clamping member 120 are fixed to the base 100 by hexagonal screws. The hexagonal screws provide a strong and secure connection, acting like a safety lock for the entire testing system. This ensures that the first clamping member 110 and the second clamping member 120 will not loosen or shift in the slightest when in the predetermined positions, greatly improving the accuracy and reliability of the test and providing a solid guarantee for the quality control of the button lithium battery packaging 5.

[0058] Although the technical solution of this utility model has been disclosed above, it is not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
