Description

Technical Field

[0001] The utility model relates to the technical field of copper foil detection, and particularly relates to a tensile test device for copper foil. Background Art

[0002] As an important basic material, copper foil plays a core role in the manufacturing of printed circuit boards (PCBs), lithium-ion batteries and other electronic devices. The quality of copper foil directly affects the performance and reliability of electronic products. Among them, the tensile characteristics of copper foil are one of the key indicators for evaluating its mechanical properties. Therefore, developing an efficient and accurate copper foil tensile test device is crucial for ensuring product quality.

[0003] However, due to the thin and soft nature of copper foil, traditional tensile test devices usually use hard clamping to fix the copper foil before performing tensile tests. Hard clamping is likely to damage the copper foil during the clamping process, and impurities often fall on the clamping part during the clamping process. When clamping, these fine impurities come into contact with the copper foil, resulting in scratches and other marks on the surface of the copper foil, which are easily damaged during the test process, affecting the test results. Summary of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a tensile test device for copper foil that can prevent copper foil from being damaged.

[0005] The utility model provides the following technical solutions: A tensile test device for copper foil, including a support assembly, two clamping mechanisms respectively arranged on the upper and lower sides of the support assembly for clamping the copper foil, one of the clamping mechanisms is slidably connected to the support assembly, and the other clamping mechanism is fixedly connected to the support assembly. The tensile test device further includes a metering mechanism arranged on the support assembly, two cleaning components and two blowers respectively arranged on the upper and lower sides of the support assembly, and the metering mechanism is connected to the slidable clamping mechanism;

[0006] The clamping mechanism includes two supports respectively arranged on both sides of the support assembly, a first slide rail arranged between the two supports, two sliding frames slidably connected to the first slide rail, clamping blocks arranged on both sliding frames, rubber pads arranged on both clamping blocks, and a driving component for driving the two sliding frames to move synchronously;

[0007] The cleaning component includes two cleaning parts slidably connected to the support assembly, and a connecting rod connecting the two cleaning parts. The cleaning parts slide on the support assembly to clean the corresponding rubber pads.

[0008] Further, the support assembly includes a base, a vertical plate fixedly connected to the base, and a plurality of ribs disposed between the base and the vertical plate. The two clamping mechanisms are disposed on the upper and lower sides of the vertical plate.

[0009] Further, the metering mechanism includes a second slide rail fixedly connected to the vertical plate, a slider slidably connected to the second slide rail, a screw rotatably connected to the second slide rail, a meter fixedly connected to the slider, and a second turning handle fixedly connected to the screw. The screw is threadedly connected to the slider, and the measuring end of the meter is connected to the first slide rail of the slidable clamping mechanism.

[0010] Further, the cleaning member is a brush or a sponge brush.

[0011] Further, the driving assembly includes a rotating shaft rotatably connected between the two supports, two external threads respectively disposed on both sides of the rotating shaft, and two first turning handles respectively fixedly connected to both ends of the rotating shaft. The rotating shaft is threadedly connected to the two sliding frames through the two external threads.

[0012] Further, positioning blocks are fixedly connected to both sides of the rotating shaft, and the two external threads are located between the two positioning blocks.

[0013] Further, the tensile testing device further includes a pushing mechanism for driving the two cleaning components to move synchronously. The pushing mechanism includes an electric slide rail disposed on the vertical plate, a column fixedly connected to the output end of the electric slide rail, and two swing rods rotatably connected between the connecting rods of the two cleaning components and the column.

[0014] The beneficial effects of the utility model are as follows: By operating the two cleaning components to clean the clamping parts of the two clamping mechanisms respectively, when cleaning the clamping parts of the clamping mechanisms, the blower will blow away the impurities cleaned by the cleaning components, preventing the impurities from adhering to the clamping parts of the clamping mechanisms and causing damage to the copper foil during the tensile test. The rubber pad contacts the copper foil to clamp the copper foil. Since it is the rubber pad that contacts the copper foil, it can provide sufficient friction without damaging the copper foil, which not only enhances the friction between the sample copper foil and the rubber pad and prevents slipping, but also effectively protects the ultra-thin copper foil from being damaged during the clamping process. Moreover, the Shore hardness of the rubber pad is selected from rubber materials with a Shore hardness in the range of 40-60 degrees, and the thickness is about 1 mm, which takes into account both durability and flexibility, reduces the risk of deformation after long-term use, and lowers the maintenance cost.

[0024] A tensile test device for copper foil, as Figure 1As shown in the figure, it includes a support component, and two clamping mechanisms 4 for clamping the copper foil are respectively arranged on the upper and lower sides of the support component. One of the clamping mechanisms 4 is slidably connected to the support component, and the other clamping mechanism 4 is fixedly connected to the support component. The tensile test device further includes a metering mechanism 7 arranged on the support component, two cleaning components 5 and two blowers 6 respectively arranged on the upper and lower sides of the support component. The metering mechanism 7 is connected to the slidable clamping mechanism 4;

[0025] It can be understood that when a tensile test needs to be performed on the copper foil, first, the operator starts the two blowers 6, and then operates the two cleaning components 5 to clean the clamping parts of the two clamping mechanisms 4 respectively. When cleaning the clamping parts of the clamping mechanism 4, the blower 6 will blow away the impurities cleaned by the cleaning component 5 to prevent the clamping parts of the clamping mechanism 4 from adhering to impurities and causing damage to the copper foil during the tensile test. Then, the operator operates the two clamping mechanisms 4 to clamp the upper and lower sides of the copper foil. After clamping the copper foil, the operator operates the metering mechanism 7. The metering mechanism 7 pulls the slidable clamping mechanism 4, and the slidable clamping mechanism 4 pulls the copper foil. The tensile measurement number will be displayed on the metering mechanism 7. Thus, the operator can judge whether the copper foil meets the requirements by observing the tensile measurement number displayed on the metering mechanism 7.

[0026] As Figure 3 shown in the figure, the clamping mechanism 4 includes two supports 41 respectively arranged on both sides of the support component, a first slide rail 42 arranged between the two supports 41, two sliding frames 43 slidably connected to the first slide rail 42, clamping blocks 44 arranged on both of the two sliding frames 43, rubber pads 45 arranged on both of the two clamping blocks 44, and a driving component for driving the two sliding frames 43 to move synchronously;

[0027] It can be understood that the operator operates the driving component, the driving component drives the sliding frames 43 to move towards each other, the sliding frames 43 moving towards each other drive the clamping blocks 44 to move towards each other, and the clamping blocks 44 moving towards each other drive the rubber pads 45 to move towards each other. Finally, the rubber pads 45 contact the copper foil and clamp the copper foil. Since it is the rubber pads 45 that contact the copper foil, sufficient friction can be provided without damaging the copper foil. This not only enhances the friction between the sample copper foil and the rubber pads 45 and prevents slipping, but also effectively protects the ultra-thin copper foil from being damaged during the clamping process. Moreover, the rubber pads 45 are made of rubber materials with a Shore hardness in the range of 40 - 60 degrees and a thickness of about 1 mm, which takes into account both durability and flexibility, reduces the risk of deformation after long-term use, and lowers the maintenance cost.

[0028] As Figure 5As shown, the cleaning assembly 5 includes two cleaning members 52 slidably connected to the support assembly, and a connecting rod 51 connected between the two cleaning members 52. The cleaning member 52 slides on the support assembly to clean the corresponding rubber pad 45, and the cleaning member 52 is a brush or a sponge brush.

[0029] It can be understood that the operator can push the connecting rod 51, and the connecting rod 51 drives the two cleaning members 52 to clean the rubber pad 45.

[0030] The support assembly includes a base 1, a vertical plate 2 fixedly connected to the base 1, and a plurality of ribs 3 arranged between the base 1 and the vertical plate 2. Two clamping mechanisms 4 are arranged on the upper and lower sides of the vertical plate 2.

[0031] Among them, the base 1 is in contact with the ground, the ribs 3 are used to support the vertical plate 2, and the vertical plate 2 is used to install the clamping mechanism 4, the metering mechanism 7, two cleaning assemblies 5 and two blowers 6.

[0032] As Figure 4 shown, the metering mechanism 7 includes a second slide rail 71 fixedly connected to the vertical plate 2, a slider 73 slidably connected to the second slide rail 71, a screw rod 72 rotatably connected to the second slide rail 71, a meter 74 fixedly connected to the slider 73, and a second turning handle 75 fixedly connected to the screw rod 72. The screw rod 72 is threadedly connected to the slider 73, and the measuring end of the meter 74 is connected to the first slide rail 42 of the slidable clamping mechanism 4.

[0033] It can be understood that the operator can rotate the second turning handle 75. The second turning handle 75 drives the screw rod 72 to rotate. The screw rod 72 drives the slider 73 to move upward. The slider 73 drives the meter 74 to move upward. The measuring end of the meter 74 pulls the slidable clamping mechanism 4 to move upward to perform a tensile test on the copper foil. The tensile value can be known from the meter 74, and thus the tensile resistance value of the copper foil can be judged.

[0034] The driving assembly includes a rotating shaft 46 rotatably connected between two supports 41, two external threads 47 respectively arranged on both sides of the rotating shaft 46, and two first turning handles 49 respectively fixedly connected to both ends of the rotating shaft 46. The rotating shaft 46 is threadedly connected to two sliding frames 43 through the two external threads 47.

[0035] It can be understood that the operator can rotate the first turning handle 49 on the left or the first turning handle 49 on the right according to his habit. By rotating the first turning handle 49, the rotating shaft 46 is driven to rotate. The rotation of the rotating shaft 46 drives the rotation of the two external threads 47. The two external threads 47 drive the two sliding frames 43 to move towards each other, so that the rubber pads 45 clamp the copper foil. When the copper foil needs to be loosened, only the first turning handle 49 needs to be rotated in reverse. The first turning handle 49 drives the rotation of the two external threads 47. The rotation of the two external threads 47 drives the two sliding frames 43 to move in the opposite direction, thereby loosening the copper foil.

[0036] Both sides of the rotating shaft 46 are fixedly connected with the positioning blocks 48, and the two external threads 47 are located between the two positioning blocks 48.

[0037] It can be understood that when the two sliding frames 43 move in the opposite direction and contact the adjacent positioning blocks 48, the two sliding frames 43 will not be able to continue moving in the opposite direction. At this time, when the cleaning member 52 moves, it can just wipe off all the impurities on the rubber pad 45. Thus, the positioning blocks 48 play a positioning role.

[0038] As Figure 5 shown, the tensile test device further includes a pushing mechanism 8 for driving the two cleaning components 5 to move synchronously. The pushing mechanism 8 includes an electric slide rail 81 provided on the vertical plate 2, a column 82 fixedly connected to the output end of the electric slide rail 81, and two swing rods 83 rotatably connected between the connecting rods 51 of the two cleaning components 5 and the column 82.

[0039] It can be understood that when the two sliding frames 43 contact the adjacent positioning blocks 48, the operator can start the electric slide rail 81. The electric slide rail 81 drives the column 82 to move towards the vertical plate 2. The column 82 pushes the two swing rods 83 to swing. The swinging of the two swing rods 83 drives the two cleaning components 5 to move in the opposite direction. Thus, the cleaning members 52 of the two cleaning components 5 will clean the corresponding rubber pads 45.

[0040] In summary, by operating the two cleaning components 5 to clean the clamping parts of the two clamping mechanisms 4 respectively, when cleaning the clamping parts of the clamping mechanism 4, the blower 6 will blow away the impurities cleaned by the cleaning component 5, preventing impurities from adhering to the clamping parts of the clamping mechanism 4 and causing damage to the copper foil during the tensile test. The rubber pad 45 contacts the copper foil to clamp the copper foil. Since it is the rubber pad 45 that contacts the copper foil, sufficient friction can be provided without damaging the copper foil, which not only enhances the friction between the sample copper foil and the rubber pad 45 and prevents slipping, but also effectively protects the ultra-thin copper foil from being damaged during the clamping process. Moreover, the Shore hardness of the rubber pad 45 is selected from rubber materials with a Shore hardness in the range of 40-60 degrees, and the thickness is about 1 mm, taking into account both durability and flexibility, reducing the risk of deformation after long-term use and lowering the maintenance cost.
