Description

Technical Field

[0001] This utility model relates to the field of foil coating machines, and in particular to a thickness detection structure for carbon-coated foil coating machines. Background Technology

[0002] A common carbon foil coating machine is a high-precision device specifically designed to uniformly coat the surface of metal foil with a carbon coating. Through processes such as slurry preparation, coating, drying, and rolling, it prepares current collector materials for lithium battery anodes or cathodes. Its core technology employs slit extrusion or transfer roller coating, combined with precision tension control, a high-temperature oven, and an online monitoring system to ensure uniform coating thickness, a defect-free surface, and high conductivity and adhesion. It is a key piece of equipment for improving battery energy density and cycle performance, and is widely used in new energy power batteries, energy storage batteries, and other fields.

[0003] In the coating process of carbon foil, traditional thickness detection methods usually rely on a single sensor for static measurement. However, this method has obvious limitations. The measurement accuracy of a single sensor is limited, making it difficult to fully reflect the uniformity of the coating layer and the actual thickness distribution. Static detection is inefficient and cannot meet the needs of real-time monitoring and full-area inspection on high-speed production lines. It can easily lead to blind spots in quality control and affect product consistency and yield.

[0004] Therefore, in the above-mentioned coating process of carbon foil, the traditional thickness detection method usually relies on a single sensor for static measurement. However, this method has obvious limitations. It is difficult to fully reflect the uniformity of the coating layer and the actual thickness distribution. It cannot meet the needs of real-time monitoring and full-width detection on high-speed production lines. It is easy to cause blind spots in quality control and affect the consistency and yield of products. Therefore, a thickness detection structure for carbon foil coating machine can be designed.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-3 This utility model provides an embodiment: the thickness detection structure of a carbon foil coating machine includes a coating frame 1; it also includes a rotating arm 7. A fixed frame 3 is fixedly connected to the upper end of the coating frame 1, a motor 4 is fixedly connected to the top of the fixed frame 3, and a rotating rod 5 is rotatably connected to the bottom of the fixed frame 3. The output end of the motor 4 is fixedly connected to the rotating rod 5, and the motor 4 is used to drive the rotating rod 5 to rotate. A connecting rod 6 is rotatably connected to the bottom of the rotating rod 5, and a rotating arm 7 is rotatably connected to the upper end of the connecting rod 6. A six-pole joint is fixedly connected to the bottom of the rotating arm 7. A probe 9 is fixedly connected to the bottom of the mounting bracket 3, and the rotating block 8 is rotatably connected to the rotating arm 7. The rotating rod 5 in the middle is driven to rotate by the motor 4. The rotating rod 5 drives the connecting rod 6 to rotate. The connecting rod 6 then pushes the rotating arm 7 to swing back and forth. At the same time, the rotating arm 7 can cover the entire width of the foil. The six probes 9 are installed in a ring on the rotating arm 7 to detect the carbon layer after coating. This dynamic scanning can see in real time whether the coating thickness of the entire foil is uniform, avoid blind spots in quality control, and improve product consistency and yield.

[0024] Please see Figures 2-5In this embodiment, a foil body 2 is provided at the upper end of the coating frame 1. A second motor 10 is fixedly connected to the right end of the coating frame 1. A foil roll 20 is rotatably connected to the inner side of the coating frame 1. The output end of the second motor 10 is fixedly connected to the foil roll 20. The second motor 10 drives the foil roll 20 to rotate and release the foil body 2. The second motor 10 is used to drive the foil roll 20 to rotate. A third motor 16 is fixedly connected to the right end of the coating frame 1. A second foil roll 17 is rotatably connected to the inner side of the coating frame 1. The third motor 16 drives the foil roll 17 to rotate and rewind the foil body 2 after carbon coating. The output end of the third motor 16 is fixedly connected to the foil roll 17. The third motor 16 is used to drive the foil roll 17 to rotate. A long rod 11 is fixedly connected inside the coating frame 1. The foil body 2 passes through the underside of the long rod 11. The long rod 11 keeps the foil body 2 flat during carbon coating.

[0025] Please see Figures 1-5 In this embodiment, a coating box 12 is fixedly connected inside the coating frame 1. A coating tank 13 is provided at the bottom of the coating box 12. The coating enters the coating box 12 through an external pipe and is evenly coated onto the foil body 2 by the coating box 12 through the coating tank 13. Four fixing rods 14 are fixedly connected inside the coating frame 1. A dryer 15 is fixedly connected to the top of the coating frame 1. The foil body 2 slides over the fixing rods 14 to keep the foil body 2 flat. The dryer 15 quickly dries the coating on the foil body 2. A fixing plate 18 is fixedly connected to the inner side of the coating frame 1. Two fans 19 are fixedly connected inside the fixing plate 18. After the foil body 2 is dried, it passes through the fans 19. The fans 19 blow air to cool the foil body 2 and the coating, which facilitates subsequent winding.

[0026] During operation, motor 210 drives foil roll 120 to rotate and release foil body 2. Motor 316 drives foil roll 217 to rotate and rewind the carbon-coated foil body 2. The foil body 2 passes under the long rod 11, which keeps the foil body 2 flat during carbon coating. The coating material enters the coating box 12 through the external pipe and is evenly applied to the foil body 2 through the coating tank 13. Then, the foil body 2 slides over the fixing rod 14 to keep it flat. At the same time, motor 14 is started to drive the rotating rod 5 to rotate, and the rotating rod 5 drives the connecting rod 6 to rotate on the rotating rod 5. Simultaneously, the connecting rod 6 drives the rotating arm 7 to swing laterally back and forth, allowing the rotating arm 7 to cover the entire width of the foil. Six sets of probes 9 arranged in a ring on the rotating arm 7 detect the carbon-coated foil body 2. Through dynamic scanning path planning, full-width detection without blind spots is achieved. Then, the dryer 15 quickly dries the coating on the foil body 2. After drying, the foil body 2 passes through the fan 19, which blows air to cool the foil body 2 and the coating, facilitating subsequent winding. The second motor 10 is connected to the internal drum of the first foil roll 20, and the third motor 16 is connected to the internal drum of the second foil roll 17.

[0027] Through the above steps, motor 4 drives rotating rod 5 to rotate, rotating rod 5 drives connecting rod 6 to rotate on rotating rod 5, and connecting rod 6 drives rotating arm 7 to swing laterally back and forth, so that rotating arm 7 can cover the entire width of foil. Six sets of probes 9 arranged in a ring on rotating arm 7 detect the carbon-coated foil body 2. Through dynamic scanning path planning, full-width detection without blind spots is achieved, which solves the problem that in the coating process of carbon-coated foil, traditional thickness detection methods usually rely on a single sensor for static measurement, which is difficult to fully reflect the uniformity of the coating layer and the actual thickness distribution. At the same time, it cannot meet the requirements of real-time monitoring and full-width detection, which can easily lead to blind spots in quality control and affect the consistency and yield of products.
