Description

Technical Field

[0001] This utility model belongs to the field of carbon-coated copper foil technology, specifically relating to a device for testing the coating strength of carbon-coated copper foil. Background Technology

[0002] Carbon-coated copper foil is widely used in the electronics, communications, and new energy fields. As an important component of batteries, conductive materials, and circuit boards, its coating strength directly affects the reliability and service life of the products. Traditional coating strength testing methods suffer from problems such as low accuracy and complex testing processes. Therefore, it is of great significance to develop a high-precision and high-efficiency carbon-coated copper foil coating strength testing device. This device can accurately measure the adhesion between the coating and the substrate, providing a reliable basis for coating quality control and meeting the needs of industrial production.

[0003] Chinese patent CN220729991U discloses a device for testing the coating strength of carbon-coated copper foil, including a testing platform and a pull-wiping device. A first connecting plate and a second connecting plate, symmetrically distributed on the left and right sides, are fixedly installed on the top of the testing platform. The first and second connecting plates are hinged to one end of a first pressure rod and one end of a second pressure rod, respectively. The first and second pressure rods are used to press the two ends of the carbon-coated copper foil to be tested. A recessed guide rail is provided on the top of the testing platform, located between the first and second pressure rods. The carbon-coated copper foil to be tested is placed in the guide rail. The pull-wiping device is used to roll and wipe the top surface of the carbon-coated copper foil to be tested. This patent can reliably test the coating strength of carbon-coated copper foil, accurately characterize the state of the coating on the carbon-coated copper foil, and effectively eliminate the manual wiping errors present in existing manual wiping methods.

[0004] However, the current device has the following problems: wrinkles appear in the coating during the testing process, which affects the contact area between the coating and the substrate, affects the stability and reliability of the strength test, and affects the evaluation of the coating quality. Therefore, we propose a testing device for the strength of carbon-coated copper foil coating. Utility Model Content

[0005] The purpose of this invention is to provide a device for testing the strength of carbon-coated copper foil, which can solve the problem in related technologies where the coating wrinkles during the testing process, affecting the contact area between the coating and the substrate, thus affecting the stability and reliability of the strength test and the evaluation of the coating quality.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A device for testing the strength of carbon-coated copper foil includes a testing platform. The top of the testing platform is equipped with an anti-wrinkle device to prevent wrinkles in the carbon-coated copper foil during testing. The anti-wrinkle device includes two fixing blocks (I), the bottoms of which are fixedly connected to the top of the testing platform. A drive motor is fixedly connected to the side of one of the fixing blocks. A bidirectional threaded rod is fixedly connected to the output shaft of the drive motor. Two threaded sleeves are threaded onto the threaded surfaces of the bidirectional threaded rod with opposite thread directions. Two fixing blocks (II) are fixedly connected to the top of the testing platform. A sliding rod is fixedly connected between the two fixing blocks (II). Two sliding sleeves are slidably connected to the circumferential surface of the sliding rod. A base plate is fixedly connected to the side of each of the two threaded sleeves, and a pressure plate is slidably connected to the side of each of the two threaded sleeves.

[0008] The top of the testing platform is fixedly connected to a fixed plate, and a handrail is slidably connected to the inner wall of the fixed plate. A sleeve is fixedly connected to the circumferential surface of the handrail, and a vertebral seat is fixedly connected to the circumferential surface of the sleeve. A pulley is rotatably connected to the inner wall of the vertebral seat, and a guide rail is provided on the top of the testing platform.

[0009] Both ends of the bidirectional threaded rod are rotatably connected to the sides of the two fixed blocks. The sides of the two base plates away from the threaded sleeve are fixedly connected to the sides of the two sliding sleeves. The sides of the two pressure plates away from the threaded sleeve are slidably connected to the sides of the two sliding sleeves.

[0010] The top of the two base plates is provided with an anti-detachment device to prevent the coating from peeling off due to inappropriate detection force. The anti-detachment device includes multiple fixed cones, the bottom of which is fixedly connected to the top of the two base plates. The sides of the two threaded sleeves are fixedly connected to connecting plates. The inner walls of the two connecting plates are slidably connected to moving rods. The tops of the two moving rods are fixedly connected to moving blocks.

[0011] The two connecting plates are fixedly connected to the sides of the two sliding sleeves on the side away from the threaded sleeve, and springs are provided between the two connecting plates and the two pressure plates.

[0012] Both pressure plates have holes at their tops to facilitate the passage of the fixing cone, and both connecting plates have holes at their tops to facilitate the passage of the moving rod.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This invention utilizes an anti-wrinkle device to coordinate the drive motor, bidirectional threaded rod, threaded sleeve, sliding sleeve, base plate, and pressure plate. The carbon-coated copper foil is placed between the pressure plate and the base plate. Activating the drive motor causes the output shaft to rotate, which in turn rotates the bidirectional threaded rod. This rotation causes the two threaded sleeves to move in opposite directions, which in turn moves the two base plates in opposite directions. The two base plates then move the two sliding sleeves in opposite directions, and finally, the two threaded sleeves move the two pressure plates in opposite directions. This opposing movement of the base plates and pressure plates stretches the carbon-coated copper foil coating, preventing wrinkles and ensuring its uniformity and integrity, thus improving the accuracy of the test results.

[0015] This invention utilizes an anti-detachment device to coordinate the connecting plate, moving rod, moving block, spring, and fixed cone. The two base plates move in opposite directions, causing the two fixed cones to move in opposite directions as well. A hole is drilled in the carbon-coated copper foil, which is then fixed to the circumference of the fixed cone. Pulling the moving block upwards causes the moving rod to move upwards, which in turn causes the pressure plate to move upwards. The pressure plate moves upwards, compressing the spring. Releasing the moving block, the pressure plate returns to its original position and moves downwards under the spring's elastic force. This downward movement of the pressure plate presses down on the carbon-coated copper foil. The fixed cone prevents the coating from detaching from the carbon-coated copper foil due to excessive force applied during strength testing, thus ensuring the accuracy of the test.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-5 As shown, a device for testing the strength of carbon-coated copper foil includes a testing platform 1, which is horizontally arranged. The top of the testing platform 1 is equipped with an anti-wrinkle device 8 to prevent wrinkles in the carbon-coated copper foil during testing. The anti-wrinkle device 8 includes two fixing blocks 81, the bottoms of which are fixedly connected to the top of the testing platform 1. A drive motor 82 is fixedly connected to the side of one of the fixing blocks 81. A bidirectional threaded rod 83 is fixedly connected to the output shaft of the drive motor 82. Two threaded sleeves 84 are threaded onto the threaded surfaces of the bidirectional threaded rod 83 with opposite thread directions. The threaded sleeves 84 contact the testing platform 1 to prevent rotation. Two fixing blocks 85 are fixedly connected to the top of the testing platform 1, and a sliding rod 86 is fixedly connected between the two fixing blocks 85. The circumferential surface of rod 86 is slidably connected to two sliding sleeves 87. The sides of the two threaded sleeves 84 are fixedly connected to base plates 88. The sides of the two threaded sleeves 84 are slidably connected to pressure plates 89. The top of the detection platform 1 is fixedly connected to a fixed plate 2. The inner wall of the fixed plate 2 is slidably connected to a handrail 3. The circumferential surface of the handrail 3 is fixedly connected to a sleeve 4. The circumferential surface of the sleeve 4 is fixedly connected to a cone seat 5. The inner wall of the cone seat 5 is rotatably connected to a pulley 6 for rolling wiping. The top of the detection platform 1 is provided with a guide rail 7. The two ends of the bidirectional threaded rod 83 are rotatably connected to the sides of two fixed blocks 81. The sides of the two base plates 88 away from the threaded sleeves 84 are fixedly connected to the sides of the two sliding sleeves 87. The sides of the two pressure plates 89 away from the threaded sleeves 84 are slidably connected to the sides of the two sliding sleeves 87.

[0025] According to the above structure, the carbon-coated copper foil coating is placed between the pressure plate 89 and the base plate 88. The drive motor 82 is started, and the rotation of the output shaft of the drive motor 82 drives the bidirectional threaded rod 83 to rotate. The rotation of the bidirectional threaded rod 83 drives the two threaded sleeves 84 to move in opposite directions. The two threaded sleeves 84 move in opposite directions, which in turn drives the two base plates 88 to move in opposite directions. The two base plates 88 move in opposite directions, which in turn drives the two sliding sleeves 87 to move in opposite directions. The two threaded sleeves 84 move in opposite directions, which in turn drives the two pressure plates 89 to move in opposite directions. The two base plates 88 and the two pressure plates 89 move in opposite directions to stretch the carbon-coated copper foil coating, avoid wrinkles in the carbon-coated copper foil coating, ensure the uniformity and integrity of the coating, and improve the accuracy of the test results.

[0026] like Figures 1-5 As shown, the tops of the two base plates 88 are provided with anti-detachment devices 9 to prevent the coating from falling off due to inappropriate detection force. The anti-detachment device 9 includes multiple fixed cones 95, the bottoms of which are fixedly connected to the tops of the two base plates 88. The fixed cones 95 are cone-shaped to facilitate the fixing of the carbon copper foil coating. The sides of the two threaded sleeves 84 are fixedly connected with connecting plates 91. The inner walls of the two connecting plates 91 are slidably connected with moving rods 92. The tops of the two moving rods 92 are fixedly connected with moving blocks 93. The side of the two connecting plates 91 away from the threaded sleeves 84 is fixedly connected to the side of the two sliding sleeves 87. Springs 94 are provided between the two connecting plates 91 and the two pressure plates 89. The springs 94 provide pressure. The tops of the two pressure plates 89 are provided with holes for the fixed cones 95 to pass through. The tops of the two connecting plates 91 are provided with holes for the moving rods 92 to pass through.

[0027] According to the above structure, the two base plates 88 move in opposite directions, causing the two fixed cones 95 to move in opposite directions. The carbon-coated copper foil coating is drilled and fixed on the circumferential surface of the fixed cones 95. The moving block 93 is pulled upward, and the upward movement of the moving block 93 causes the moving rod 92 to move upward. The upward movement of the moving rod 92 causes the pressure plate 89 to move upward. The upward movement of the pressure plate 89 compresses the spring 94, releasing the moving block 93. Under the elastic force of the spring 94, the pressure plate 89 returns to its original position and moves downward. The downward movement of the pressure plate 89 presses down on the carbon-coated copper foil coating. The fixed cones 95 prevent the coating from peeling off due to excessive force applied during the strength test, which would affect the accuracy of the test.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
