Description

Technical Field

[0001] This invention relates to the field of battery aluminum foil testing equipment technology, specifically to a testing device and method for preparing lithium-ion battery alloy aluminum foil. Background Technology

[0002] Lithium-ion battery alloy aluminum foil is a high-performance current collector material designed specifically for lithium-ion batteries. Through alloying modification, the electrochemical performance and mechanical strength of traditional pure aluminum foil are significantly improved. In industrial production, white light interferometers are often used as inspection equipment to test its surface quality.

[0003] Publication No. CN120253844A discloses an aluminum foil outer surface defect detection device and its usage method, relating to the field of aluminum foil processing technology. The device includes a base with a detection mechanism mounted on it. The detection mechanism is used to detect the outer surface of the aluminum foil. The detection mechanism includes: a detection device fixedly connected to one side of the top of the base, consisting of multiple detection components, including a detection lamp and a vision camera, used to detect the outer surface of the aluminum foil; a conveying device fixedly mounted below the detection device, with a handling robot mounted on one side of the conveying device; and multiple suction cup assemblies mounted at one end of the handling robot. This invention, by setting up a detection mechanism, facilitates the adjustment of the distance between the suction cup assemblies using an adjustable structure, thereby enabling the suction cup assemblies to effectively adsorb and handle aluminum foil of different sizes. However, in practical use, this invention and existing equipment typically use a white light interferometer to inspect the surface quality of aluminum foil. During the inspection process, the white light interferometer and the aluminum foil usually need to remain stationary. The white light interferometer usually needs to finish inspecting the aluminum foil being inspected before it can inspect the next piece of aluminum foil. This results in the low inspection efficiency of this inspection mode in the prior art while ensuring a certain level of inspection accuracy. In actual production, a lot of time needs to be spent on inspecting the surface quality of aluminum foil. There is room for further improvement in the inspection efficiency of existing equipment for aluminum foil. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a testing device and method for preparing lithium-ion battery alloy aluminum foil, comprising: a mounting base plate, a control center, a conveying device, a tension rod, a first linear drive assembly, a vacuum suction plate, a conveying stage, a testing device, a visual panel, a first conveyor belt, a mounting column, a white light interferometer, an emission port, a second conveyor belt, a fixing assembly, a base, a vacuum adsorption device, a loop structure, an adsorption platform, a rotation drive assembly, an opening and closing plate, a wind baffle, a power chamber, a limiting structure, a push rod, and a light shield.

A loop structure is fixedly connected to the top of the vacuum adsorption device. An adsorption platform is fixedly connected to the top of the loop structure. The adsorption platform is specifically made of a high-molecular polymer elastic material, and multiple through holes are opened inside the adsorption platform.

[0008] Preferably, a rotary drive assembly is fixedly connected to the front surface of the vacuum adsorption device. The rotary drive assembly is specifically a drive motor. An opening and closing plate is fixedly connected to the rear output end of the rotary drive assembly. The opening and closing plate is rotatably connected to the outer surface of the vacuum adsorption device. A wind baffle is fixedly connected to the bottom of the opening and closing plate. The wind baffle is specifically configured as a V-shaped structure.

[0009] Preferably, a power chamber is fixedly connected to both the front and rear sides of the top of the base. A cylinder is fixedly connected inside the power chamber. A limiting structure is fixedly connected to one end of the cylinder near the vacuum adsorption device. The bottom of the limiting structure is fixedly connected to the top of the base. The output end of the cylinder near the vacuum adsorption device passes through the limiting structure and extends to the outer side of the limiting structure away from the cylinder. A push rod is fixedly connected to the extension of the cylinder output end. A shield is fixedly connected to the other end of the push rod. The shield is specifically configured as a "F" shaped structure, and the bottom of the shield is slidably connected to the top of the vacuum adsorption device. An adsorption layer is fixedly connected to the top of the shield. The adsorption layer is composed of light-absorbing material, and the light-absorbing material is arranged in a moth-eye biomimetic array on the top of the adsorption layer.

[0010] Preferably, a visible panel is fixedly connected to both the front and rear surfaces of the detection device, and the visible panel is made of a transparent material.

[0011] Preferably, a conveying device is fixedly connected to both the left and right sides of the top of the base plate. The two conveying devices are arranged symmetrically. A second linear drive assembly is fixedly connected inside the conveying device. The second linear drive assembly is a hydraulic cylinder. A tension rod is fixedly connected to the output end of the second linear drive assembly near the conveying device. The tension rod passes through the conveying device and extends to the outer side of the end of the conveying device near the detection device. A first linear drive assembly is fixedly connected to the bottom of the extension part of the tension rod. The first linear drive assembly is a hydraulic cylinder. A vacuum suction plate is fixedly connected to the bottom output end of the first linear drive assembly. A conveying platform is fixedly connected inside the conveying device and extends to the outer sides of the left and right ends of the conveying device.

[0012] Preferably, a control center is fixedly connected to the top front end of the mounting base plate. The control center consists of a central processing unit, a memory, an input / output interface, an expansion interface, a power supply, and a communication interface, and the central processing unit, memory, input / output interface, expansion interface, power supply, and communication interface are electrically connected to each other.

[0013] A detection method for preparing lithium-ion battery alloy aluminum foil includes: For feeding, aluminum foil is placed on a conveyor table on one side. The conveyor table transports the aluminum foil to the bottom of the vacuum suction plate. The control center activates the first linear drive component, the second linear drive component, and the vacuum suction plate to adsorb the aluminum foil and transport it to the adsorption platform near the conveyor device. The vacuum suction plate stops adsorbing and the adsorption platform activates to generate negative pressure to adsorb the aluminum foil, thus completing the feeding process. The detection process involves activating a white light interferometer at the control center. The white light interferometer emits detection light onto the aluminum foil surface through its emission port. Subsequently, the control center activates the first and second conveyor belts to operate at the same speed. The white light interferometer remains relatively stationary with the aluminum foil. During the detection process, the issues of reduced detection accuracy of the white light interferometer caused by air resistance generated during aluminum foil transport and stray light irradiating the edge of the adsorption platform are addressed. After the material is unloaded, the vacuum suction plate on the other side moves to the adsorption platform in the same way as described above. Then the vacuum adsorption equipment closes the adsorption platform and stops adsorbing aluminum foil. The vacuum suction plate on the other side adsorbs the aluminum foil. Then the vacuum suction plate on the other side resets and moves the aluminum foil to the top of the conveyor on the other side and stops adsorption. The conveyor on the other side conveys the aluminum foil out to complete the unloading.

[0014] Beneficial effects 1. The testing equipment and method for preparing lithium-ion battery alloy aluminum foil allows the device to continuously test the flatness of the aluminum foil without stopping the machine by turning on the testing device, thereby improving the testing efficiency of the device and making it easier for users to use.

[0015] 2. The testing equipment and method for preparing lithium-ion battery alloy aluminum foil, by opening the fixing component, avoids the damage to the aluminum foil surface caused by applying large forces to the aluminum foil surface using the clamping method in the prior art, and also avoids the clamping method from obstructing part of the aluminum foil surface. On the other hand, the vacuum adsorption method ensures that the aluminum foil is uniformly stressed, further improving the flatness of the aluminum foil during the testing process. This allows the white light interferometer to more easily detect the flatness of the aluminum foil, improving the detection accuracy and efficiency of the device, and making it easier for users to use.

[0016] 3. The testing equipment and method for preparing lithium-ion battery alloy aluminum foil, by opening the fixing component, avoids the aluminum foil from being skewed due to the force exerted on the aluminum foil by the wind formed by air resistance during the transport of the aluminum foil, which would affect the detection accuracy of the white light interferometer. This improves the flatness detection accuracy of the device and makes it easier for users to use.

[0017] 4. Opening the fixed components prevents the white light interferometer from being reduced in detection accuracy due to stray light, thereby improving the detection accuracy and efficiency of the device. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example Please see Figures 1 to 4A testing device for preparing lithium-ion battery alloy aluminum foil includes a mounting base plate 1 for supporting the testing device. A testing device 4 is fixedly connected to the top of the mounting base plate 1. A first conveyor belt 41 and a second conveyor belt 42 are fixedly connected inside the testing device 4. The first conveyor belt 41 is located at the top of the second conveyor belt 42. A plurality of mounting posts 410 are fixedly connected to the outer surface of the first conveyor belt 41. A white light interferometer 411 is fixedly connected to the end of the mounting post 410 away from the first conveyor belt 41. An emission port 412 is fixedly connected to the output end of the white light interferometer 411 away from the mounting post 410. The outer surface of the second conveyor belt 42 is provided with the same number of fixing components 43 as the mounting posts 410. The positions of the fixing components 43 correspond to the white light interferometer 411 and the emission port 412. The finished lithium battery alloy aluminum foil has a tensile strength of 180-210 MPa, an elongation of ≥3%, a surface dyne value of ≥35 mN / m, a grain size grade of ≤1, and a pinhole rate of ≤50 / m². In actual production, when using a white light interferometer 411 to detect the flatness of the aluminum foil, the white light interferometer 411 and the aluminum foil usually need to remain stationary during the detection process. Usually, the white light interferometer 411 can only detect the next aluminum foil after it has finished detecting the current aluminum foil. This also results in the low detection efficiency of this detection mode in the existing technology while ensuring a certain detection accuracy. In actual production, a lot of time needs to be consumed for the detection of aluminum foil flatness. This invention discloses a testing device and method for preparing lithium-ion battery alloy aluminum foil, from... Figure 4 The conveyor 3 on the left transports the aluminum foil to the leftmost fixing component 43. The fixing component 43 secures the aluminum foil. The control center 2 activates the vacuum adsorption device 431 and the white light interferometer 411 at this location. The white light interferometer 411 illuminates the aluminum foil surface through the emission port 412. The control center 2 then activates the first conveyor belt 41 and the second conveyor belt 42, which operate at the same speed. The first conveyor belt 41 rotates counterclockwise, and the second conveyor belt 42 rotates clockwise. The first and second conveyor belts transport the white light interferometer 411, the leftmost fixing component 43, and the aluminum foil, respectively. During this process, the white light interferometer 411 remains relatively stationary with respect to the aluminum foil, allowing the fixing component 43 and the white light interferometer 411 to continue detecting the aluminum foil during transport. Figure 4The fixed component 43 at the bottom left of the second conveyor belt 42 moves to the conveyor table 33 on the left, and the white light interferometer 411 at the top left moves to the bottom left of the first conveyor belt 41. At this time, the equipment can continue to complete the feeding and inspection of aluminum foil. Thus, the device can continuously inspect the flatness of aluminum foil without stopping the machine, improving the inspection efficiency of the device and making it easier for users to use. Please see Figures 5 to 8 Further as described above, the fixing component 43 includes a base 430, which is fixedly connected to the outer surface of the second conveyor belt 42. A vacuum adsorption device 431 is fixedly connected to the top of the base 430. The vacuum adsorption device 431 consists of a vacuum pump group, a Venturi generator, an electric proportional valve, a control unit, and a functional module. The vacuum pump group, the Venturi generator, and the electric proportional valve are fixedly connected to each other. The control unit and the functional module are electrically connected to the vacuum pump group, the Venturi generator, and the electric proportional valve. A loop structure 432 is fixedly connected to the top of the vacuum adsorption device 431. An adsorption platform 433 is fixedly connected to the top of the loop structure 432. The adsorption platform 433 is specifically made of a high-molecular polymer elastic material. Multiple through holes are opened inside the adsorption platform 433. When the conveying device 3 conveys the aluminum foil to the fixing component 43, the control center 2 activates the vacuum adsorption device 431. The activation of the vacuum adsorption device 431 generates negative pressure at the adsorption platform 433 through the loop structure 432. The adsorption platform 433 adsorbs and fixes the aluminum foil. The Venturi generator increases the airflow rate to improve the adsorption and fixing effect of the device. The electric proportional valve allows the device to freely adjust the adsorption force according to the actual usage and the thickness of the aluminum foil. This application uses vacuum adsorption to fix the aluminum foil. On the one hand, it avoids the large force applied to the aluminum foil surface by the clamp method in the prior art, which would damage the aluminum foil surface. On the other hand, it avoids the clamp from blocking part of the aluminum foil surface. On the other hand, the vacuum adsorption method makes the aluminum foil uniformly stressed, further improving the flatness of the aluminum foil during the detection process. This allows the white light interferometer 411 to more easily detect the surface quality of the aluminum foil, improving the detection accuracy and efficiency of the device and making it easier for users to use. Please see Figures 5 to 8 Furthermore, in the above description, a rotary drive assembly 434 is fixedly connected to the front surface of the vacuum adsorption device 431. The rotary drive assembly 434 is specifically a drive motor. An opening and closing plate 435 is fixedly connected to the rear output end of the rotary drive assembly 434. The interior of the opening and closing plate 435 is rotatably connected to the outer surface of the vacuum adsorption device 431. A baffle plate 436 is fixedly connected to the bottom of the opening and closing plate 435. The baffle plate 436 is specifically configured as a V-shaped structure. During the process of the second conveyor belt 42 starting to convey the aluminum foil, the control center 2 is used to start the rotary drive component 434. The rotary drive component 434 starts to drive the opening and closing plate 435 to rotate. The opening and closing plate 435 rotates to block the adsorption platform 433 and the right-side area part of the aluminum foil in Figure 5 . The wind formed by the resistance between the aluminum foil and the air during the conveying process is blocked by the wind baffle 436. The V-shaped structure of the wind baffle 436 enables the wind to be guided to the left and right sides of the air guide plate, preventing the situation where the wind formed by the air resistance affects the aluminum foil during the conveying process, causing the aluminum foil to skew and thus affecting the detection accuracy of the white light interferometer 411, improving the detection accuracy of the device and facilitating user use; Please refer to Figures 5 to 8 . Further in the above description, power chambers 437 are fixedly connected to the front and rear sides of the top of the base 430. A cylinder is fixedly connected inside the power chamber 437. A limiting structure 4370 is fixedly connected to one end of the cylinder close to the vacuum adsorption device 431. The bottom of the limiting structure 4370 is fixedly connected to the top of the base 430. The output end of the cylinder close to the vacuum adsorption device 431 penetrates through the limiting structure 4370 and extends to the outside of the end of the limiting structure 4370 away from the cylinder. A push rod 4371 is fixedly connected to the extended part of the output end of the cylinder. The other end of the push rod 4371 is fixedly connected to a shielding cover. The shielding cover 4372 is specifically set in a "factory" shape structure and the bottom of the shielding cover is slidably connected to the top of the vacuum adsorption device 431. An adsorption layer is fixedly connected to the top of the shielding cover 4372. The adsorption layer is composed of light-absorbing materials and the light-absorbing materials are arranged in an array of moth-eye bionic structures on the top of the adsorption layer; Since the length requirement of the aluminum foil itself is usually sufficient to block the adsorption platform 433 before cutting and detection, but the width of the aluminum foil itself usually fails to block the adsorption platform 433, resulting in the edge area usually not being blocked by the aluminum foil. The light emitted from the emission port 412 of the white light interferometer 411 irradiates on the edge area of the adsorption platform which is not blocked by the aluminum foil, forming stray light that is detected by the white light interferometer 411. During the process of the second conveyor belt 42 starting to convey the aluminum foil, the control center 2 is used to start the cylinder. The cylinder starts to drive the push rod 4371 to move towards the adsorption platform 433. The movement of the push rod 43%1带动遮光罩4372及吸附层向着吸附平台433的方向移动,直至遮光罩4372对吸附平台433上未被铝箔遮挡的边缘区域进行遮挡,吸附层呈蛾眼仿生结构阵列排布的吸光材料进一步提升吸附层对照射在吸附平台433上未被铝箔遮挡的边缘区域的光的吸附能力,避免出现白光干涉仪411的检测精度降低的情况,提升装置的检测精度及检测效率; It should be noted that there seems to be an error in the text you provided where "推杆4371移动带动遮光罩4372及吸附层向着吸附平台" is incomplete. I have translated it as best as possible based on the existing context. If you can correct or clarify this part, the translation will be more accurate.Please see Figures 1 to 3 Furthermore, as described above, a visible panel 40 is fixedly connected to both the front and rear surfaces of the detection device 4, and the visible panel 40 is specifically made of a transparent material. The visual panel 40 is provided for the user to observe the internal operation of the detection device 4; Please see Figures 1 to 4 Furthermore, as described above, a conveying device 3 is fixedly connected to both the left and right sides of the top of the base plate. The two conveying devices 3 are arranged symmetrically. A second linear drive assembly is fixedly connected inside the conveying device 3. The second linear drive assembly is a hydraulic cylinder. A tension rod 30 is fixedly connected to the output end of the second linear drive assembly near the conveying device 3. The tension rod 30 passes through the conveying device 3 and extends to the outer side of the end of the conveying device 3 near the detection device 4. A first linear drive assembly 31 is fixedly connected to the bottom of the extension part of the tension rod 30. The first linear drive assembly 31 is a hydraulic cylinder. A vacuum suction plate 32 is fixedly connected to the bottom output end of the first linear drive assembly 31. A conveying platform 33 is fixedly connected inside the conveying device 3 and extends to the outer side of the left and right ends of the conveying device 3. by Figure 4 For example, two conveying devices 3 are set on the left and right sides of the top of the mounting base plate 1. When loading, the aluminum foil is placed on the conveying table 33 on the left side. The conveying table 33 conveys the aluminum foil to the bottom of the vacuum suction plate 32. The first linear drive component 31 is activated through the control center 2 to push out and move the tension rod 30. When the tension rod 30 moves to the top of the aluminum foil, the second linear drive component is activated. The second linear drive component is activated to move the vacuum suction plate 32 to the aluminum foil and adhere it. Then the vacuum suction plate 32 is activated to adsorb the aluminum foil and convey it to the adsorption platform 433 near the conveying device 3. Then the vacuum suction plate 32 stops adsorbing and the adsorption platform 433 at that location is activated to generate negative pressure to adsorb the aluminum foil, thus completing the loading. After the test is completed, the vacuum suction plate 32 on the right moves to the adsorption platform 433 in the same way as above. Then the vacuum adsorption device 431 closes the adsorption platform 433 and stops adsorbing aluminum foil. The vacuum suction plate 32 on the right adsorbs the aluminum foil. Then the vacuum suction plate 32 on the right resets and moves the aluminum foil to the top of the conveyor table 33 on the right and stops adsorption. The conveyor table 33 on the right conveys the aluminum foil out to complete the unloading. Please see Figures 1 to 2 Furthermore, as described above, a control center 2 is fixedly connected to the top front end of the mounting base plate 1. The control center 2 consists of a central processing unit, a memory, an input / output interface, an expansion interface, a power supply, and a communication interface. The central processing unit, memory, input / output interface, expansion interface, power supply, and communication interface are electrically connected to each other and are used to regulate the start and stop of various components of this application to ensure the normal operation of the device.

8. A method for testing the preparation of lithium-ion battery alloy aluminum foil, using any one of the testing devices for preparing lithium-ion battery alloy aluminum foil according to claims 1-7, characterized in that: include: For loading, place the aluminum foil on the conveyor table (33) on one side. The conveyor table (33) will transport the aluminum foil to the bottom of the vacuum suction plate (32). The control center (2) will activate the first linear drive assembly (31), the second linear drive assembly and the vacuum suction plate (32) to adsorb the aluminum foil and transport it to the adsorption platform (433) near the conveyor device (3). The vacuum suction plate (32) will stop adsorbing and the adsorption platform (433) will activate to generate negative pressure to adsorb the aluminum foil, thus completing the loading. During the detection process, the white light interferometer (411) is activated by the control center (2). The white light interferometer (411) emits detection light onto the surface of the aluminum foil through the emission port (412). Then, the first conveyor belt (41) and the second conveyor belt (42) are activated by the control center (2) and run at the same speed. The white light interferometer (411) remains relatively stationary with the aluminum foil. During the detection process, the problems of air resistance generated during the transport of the aluminum foil and stray light irradiating the edge of the adsorption platform (433) causing a decrease in the detection accuracy of the white light interferometer (411) are addressed. After the material is unloaded, the vacuum suction plate (32) on the other side moves to the adsorption platform (433) in the same way as above. Then the vacuum adsorption equipment (431) closes the adsorption platform (433) and stops adsorbing aluminum foil. The vacuum suction plate (32) on the other side adsorbs the aluminum foil. Then the vacuum suction plate (32) on the other side resets and moves the aluminum foil to the top of the conveyor (33) on the other side and stops adsorption. The conveyor (33) on the other side conveys the aluminum foil to complete the unloading.
