Description

Technical Field

[0001] This utility model relates to the field of copper foil performance testing equipment, specifically a strength testing device for copper foil production. Background Technology

[0002] Electrolytic copper foil, as a key material in copper-clad laminates, printed circuit boards, and lithium-ion battery negative electrode current collectors, has applications covering multiple high-tech fields such as electronic information and new energy. With the development of high-tech product components towards miniaturization, high power, multifunctionality, and high stability, the requirements for the mechanical properties of electrolytic copper foil are increasingly stringent. Heat treatment is a common method to improve the mechanical properties of copper materials; for example, annealing of bulk copper reduces the grain size, thereby improving its mechanical properties. Yang Shengfu et al. studied the changes in the mechanical properties of 9μm electrolytic copper foil during annealing at 160–240℃, finding that within 2 hours, the strength of the copper foil decreased after annealing, but its toughness increased.

[0003] However, the inherently low strength of electrolytic copper foil necessitates the exploration of effective heat treatment methods to enhance its mechanical properties. In this process, developing accurate and reliable methods and equipment for testing copper foil strength becomes crucial. Current testing equipment primarily focuses on improving the stability and accuracy of the testing process. For example, Chinese Patent Publication No. CN218212301U, published on January 3, 2023, discloses a tensile strength testing device for copper foil production. This invention utilizes a handle to rotate a rotating rod, which in turn rotates two incomplete columns. These incomplete columns then drive two adjusting rods to move relative to each other, which in turn drive two adjusting blocks to move relative to each other. The adjusting blocks, through a support rod, drive two clamping plates to move relative to each other, thus achieving the function of clamping, fixing, and unlocking the bottom ends of workpieces of different thicknesses. For example, Chinese Patent Publication No. CN215115658U discloses a device for testing the tensile strength elongation of electrolytic copper foil. This utility model improves the stability of the device by setting a retractable support plate, and does not increase the space occupied by the device when not in use, thereby reducing the probability of the device shaking or tipping over during use. The fixed structure facilitates the fixation of the support plate in the retracted state.

[0004] In the aforementioned utility model, the copper foil must first undergo a baking heat treatment process before strength testing. However, the copper foil is relatively thin and requires multiple manual handling before and after heat treatment, which easily causes wrinkles or damage. Furthermore, during clamping, the copper foil is prone to breakage or detachment from the clamping assembly, severely impacting testing efficiency and the reliability of results. Therefore, we propose a strength testing device for copper foil production to address the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a strength testing device for copper foil production, in order to solve the problems mentioned in the background art. In the current invention, it is inconvenient to control the temperature of the copper foil during use, so it is impossible to test the tensile strength of the copper foil at different temperatures, and the results are relatively simple. In addition, when clamping the copper foil, it is easy to break the copper foil, which will cause the copper foil to fall out of the clamping component, resulting in inaccurate test results.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a strength testing device for copper foil production, comprising: a testing box and a door rotatably connected to the testing box;

[0007] Also includes:

[0009] A clamping plate is provided on the upper left side of the movable plate, and a pointed cone is provided on the lower left side of the movable plate. The clamping plate and the pointed cone are also provided on the right side of the fixed plate.

[0019] 3. It is equipped with a movable plate, a clamping plate and a cone. When the copper foil is clamped, the cone can prevent the copper foil from sliding, while the clamping plate can prevent the copper foil clamped by the cone from being torn, thus enhancing the accuracy of detection.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0029] This embodiment is a strength testing device for copper foil production.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a support platform 2 is fixedly installed on the lower side of the inside of the testing box 1. A fixing plate 3 is fixedly installed on the upper left side of the support platform 2. A slot 4 is opened inside the support platform 2. A first connecting block 5 is slidably connected inside the slot 4. A movable plate 6 is fixedly connected to the upper side of the first connecting block 5. A first threaded rod 7 is rotatably connected to the right side of the movable plate 6. The first threaded rod 7 is threadedly connected to the support platform 2 through a vertical plate. A clamping plate 8 is set on the upper left side of the movable plate 6. A pointed cone 9 is set on the lower left side of the movable plate 6. The clamping plate 8 and the pointed cone 9 are also set on the right side of the fixing plate 3.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, a limiting groove 12 is provided at the rear of the inner side of the detection box 1. The limiting groove 12 is connected to the second connecting block 11 in a slot. The second connecting block 11 and the limiting groove 12 are symmetrical about the vertical central axis of the lifting platform 10. The rear side of the lifting platform 10 is fixedly connected to the second connecting block 11. A tension gauge 13 is provided on the upper side of the lifting platform 10. A second threaded rod 14 is rotatably connected to the upper side of the tension gauge 13. A fan 16 is provided inside the detection box 1. The fan 16 is located inside the mounting frame 15. Heating wires 17 are provided inside the mounting frame 15. The heating wires 17 are arranged in an array. The fan 16 and the heating wires 17 are symmetrical about the vertical central axis of the detection box 1. In addition, a door 18 is rotatably connected to the front side of the detection box 1, and an observation window is opened inside the door 18.

[0032] It should be noted that the lower side of the lifting platform 10 is also provided with a fixed plate 3, a movable plate 6, and a first threaded rod 7. The fixed plate 3 on the upper side of the support platform 2 and the fixed plate 3 on the lower side of the lifting platform 10 are on the same vertical line. When the copper foil is clamped, the second threaded rod 14 is rotated. The second threaded rod 14 will move the tension gauge 13 upward. The upward-moving tension gauge 13 will move the lifting platform 10 upward together. Since the rear side of the lifting platform 10 is provided with a second connecting block 11, the second connecting block 11 and the limiting groove 12 will play a limiting role in the lifting platform 10 during the upward movement of the lifting platform 10, preventing the lifting platform 10 from deviating or shaking, thereby ensuring that the copper foil can be pulled vertically upward, thus ensuring that the test results are more accurate. Specific Implementation Example 2

[0033] This embodiment is designed to address the problem that copper foil may detach from the clamping assembly during clamping.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first place the lower side of the copper foil on the upper side of the support platform 2. Then rotate the first threaded rod 7 on the upper side of the support platform 2. Since the position of the fixed plate 3 is fixed, rotating the first threaded rod 7 will allow the fixed plate 3 and the moving plate 6 to clamp the lower side of the copper foil. Then place the upper side of the copper foil between the fixed plate 3 and the moving plate 6 on the lower side of the lifting platform 10. Rotate the first threaded rod 7 on the lower side of the lifting platform 10 to allow the fixed plate 3 and the moving plate 6 on the lower side of the lifting platform 10 to clamp the copper foil. On the upper side, in addition, clamping plates 8 and cones 9 are provided on the inner sides of the fixed plate 3 and the movable plate 6. The clamping plates 8 and cones 9 can ensure that the copper foil is clamped without breaking the connection between the fixed plate 3 and the movable plate 6, thereby enhancing the accuracy of the test. When the copper foil is clamped, the second threaded rod 14 is rotated to move the tension gauge 13 and the lifting platform 10 upward. When the copper foil is torn, the tension gauge 13 will record the maximum tension, thereby obtaining the maximum strength of the copper foil. Specific Implementation Example 3

[0035] This embodiment is designed to address the problem of not being able to test the strength of copper foil at different temperatures.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the test chamber 1 and the chamber door 18 allow the copper foil to be placed in a sealed space. After the copper foil is clamped, the fan 16 and the heating wire 17 are turned on. The heating wire 17 will dissipate heat, and the fan 16 will blow the heat dissipated by the heating wire 17 to the surface of the copper foil. The thermometer inside the test chamber 1 can measure the temperature inside the test chamber 1. When the temperature inside the test chamber 1 reaches the set temperature, the fan 16 and the heating wire 17 are turned off, and the second threaded rod 14 is rotated until the copper foil breaks. In addition, the heating wire 17 can continuously heat the inside of the test chamber 1 to increase the temperature, thereby detecting the tensile strength of the copper foil at different temperatures.
