Description

Technical Field

[0001] This utility model relates to the field of error measurement technology, and in particular to a cathode roller runout error measuring device. Background Technology

[0002] In the electrolytic copper foil production process, the cathode roller, as the core coating roller, directly affects the thickness uniformity of 6-12μm ultrathin copper foil due to its radial runout accuracy. With the surge in demand for ultrathin copper foil from the new energy industry, international advanced standards have tightened the dynamic runout tolerance of the cathode roller to ±1.5μm. Traditional measurement methods are insufficient to meet the real-time detection requirements of modern high-speed production lines.

[0003] The measuring devices commonly used in the industry are mainly based on frame structures. Typical designs include cast iron base platforms, bidirectional screw adjustment mechanisms, and split V-shaped support seats. The working principle is to fix the cathode roller axially by manually tightening the bolts, and to use dial indicators for contact measurement. The equipment is usually equipped with counterweights to suppress vibration. During installation, multiple operators are required to coordinate the adjustment and use feeler gauges to repeatedly calibrate the parallelism between the roller and the measuring reference surface.

[0004] Existing devices suffer from a trade-off between clamping efficiency and accuracy. To achieve measurement accuracy, traditional bolt tightening methods require progressive tightening, which takes too long. More seriously, uneven force on the bolt group can cause elastic deformation of the cathode roller, severely interfering with the acquisition of real runout data. Therefore, a cathode roller runout error measurement device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cathode roller runout error measuring device, which aims to improve the problem that the traditional bolt tightening method requires progressive tightening, the whole process is too time-consuming, and more seriously, uneven force on the bolt group will cause elastic deformation of the cathode roller.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cathode roller runout error measuring device, comprising a connecting plate, a support frame slidably connected to the inner wall of the connecting plate, a measuring instrument fixedly connected to the outer wall of the support frame, a fixing block 1 fixedly connected to the upper surface of the connecting plate, a motor fixedly connected to the inner wall of the fixing block 1, a sleeve fixedly connected to the output end of the motor, a fixing seat 1 rotatably connected to the outer wall of the sleeve, a cathode roller body disposed inside the sleeve, a fixing seat 2 and a fixing seat 3 slidably connected to one end of the cathode roller body, and a sliding component disposed on the inner wall of the fixing seat 2; The sliding assembly includes a limiting block, a connecting block 1, and a spring 1. The outer wall of the limiting block is slidably connected to the inner wall of the fixed seat 2. The inner wall of the connecting block 1 is fixedly connected to the outer wall of the limiting block. One end of the spring 1 is fixedly connected to a lower surface of the connecting block. The outer wall of the limiting block is slidably connected to the inner wall of the fixed seat 3. The inner wall of the fixed seat 3 is provided with a limiting assembly.

[0007] Furthermore, the limiting assembly includes a second connecting block, a first connecting rod, and a third connecting block. The outer wall of the second connecting block is fixedly connected to the inner wall of the third fixing seat. The outer wall of the first connecting rod is fixedly connected to the inner wall of the second connecting block. The inner wall of the third connecting block is rotatably connected to the outer wall of the first connecting rod. A bolt is threadedly connected to the inner wall of the second fixing seat, and a fourth connecting block is fixedly connected to one end of the bolt.

[0008] Furthermore, a sliding block is fixedly connected to the lower surface of the fixed base, and the outer wall of the sliding block is slidably connected to the inner wall of the connecting plate.

[0009] Furthermore, a base is fixedly connected to the lower surface of the connecting plate, and a buffer block is fixedly connected to the outer wall of the base.

[0010] Furthermore, a fixing block two and a connecting seat one are fixedly connected to the lower surface of the base, a rotating block one is rotatably connected to the inner wall of the fixing block two, and a connecting rod two is rotatably connected to the inner wall of the rotating block one.

[0011] Furthermore, a fixing block three is fixedly connected to the outer wall of the connecting rod two, a spring two is fixedly connected to the lower surface of the fixing block three, and a connecting plate two is fixedly connected to one end of the spring two.

[0012] Furthermore, a rotating block two is rotatably connected to the outer wall of the connecting rod two, and a fixed seat four is rotatably connected to the outer wall of the rotating block two.

[0013] Furthermore, a connecting seat 2 is fixedly connected to the upper surface of the connecting plate 2, a spring 3 is fixedly connected to the outer wall of the connecting seat 2, and a fixing block 4 is slidably connected to the outer wall of both the connecting seat 2 and the connecting seat 1.

[0014] This utility model has the following beneficial effects: 1. In this utility model, a preliminary limiting component is formed. By pressing the connecting block one, the limiting block is driven to slide up and down within the fixed seat two and fixed seat three. The fixed seat three slides through the sliding block, driving the limiting block to slide into the fixed seat two. At this time, the connecting block one is released, and the compressed spring one causes the connecting block one and the limiting block to automatically bounce upward, causing the limiting block to slide upward in the sliding groove within the fixed seat two, forming a secondary limiting. This enables rapid installation of the cathode roller body, improving efficiency. At the same time, the double limiting ensures that the clamping force is evenly distributed on the cathode roller body, avoiding deformation due to single-point force and ensuring fixed stability.

[0015] 2. In this utility model, there is a buffer block on the base to absorb vibrations from below. The connecting seat 1 slides down inside the fixed block 4 and cooperates with the connecting seat 2 to compress the spring 3 for buffering. The fixed blocks 2 on both sides cause the rotating block 1 to drive the connecting rod 2 and the rotating block 2 to slide, so that the fixed block 3 compresses the spring 2 to achieve a buffering effect again. This provides a stable and reliable physical environment for high-precision detection and effectively avoids the problem of detection data distortion caused by vibration. Attached Figure Description

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.

[0019] Reference Figures 1-5 An embodiment of this utility model provides a cathode roller runout error measuring device, including a connecting plate 1. The connecting plate 1 provides a sliding track for the sliding block 11 to guide the movement of the fixed seat 3 10, and at the same time provides a lateral sliding path for the support frame 8 to facilitate multi-point detection by the measuring instrument 7. The support frame 8 is slidably connected to the inner wall of the connecting plate 1, and the measuring instrument 7 is fixedly connected to the outer wall of the support frame 8. The measuring instrument 7 monitors the running error of the cathode roller body 6 in real time during rotation, providing data support for accuracy evaluation. A fixed block 2 is fixedly connected to the upper surface of the connecting plate 1, and a motor 3 is fixedly connected to the inner wall of the fixed block 2. A sleeve 5 is fixedly connected to the output end of the motor 3. The sleeve 5 cooperates with one end of the cathode roller body 6 to achieve quick insertion and positioning, and at the same time serves as an intermediate carrier for power transmission of the motor 3. A fixed seat 4 is rotatably connected to the outer wall of the sleeve 5. The cathode roller body 6 is arranged inside the sleeve 5. A fixed seat 2 9 and a fixed seat 3 10 are slidably connected to one end of the cathode roller body 6. A sliding component is arranged on the inner wall of the fixed seat 2 9. The sliding assembly includes a limiting block 15, a connecting block 13, and a spring 14. The outer wall of the limiting block 15 is slidably connected to the inner wall of the fixed seat 2 9, and the inner wall of the connecting block 13 is fixedly connected to the outer wall of the limiting block 15. Driven by the connecting block 13, the limiting block 15 slides within the fixed seat 2 9 and the fixed seat 3 10, achieving secondary locking of the cathode roller body 6 by embedding in the sliding groove of the fixed seat 2 9. One end of the spring 14 is fixedly connected to the lower surface of the connecting block 13. When the spring 14 is compressed, it stores elastic potential energy. After releasing the connecting block 13, it releases energy, pushing the connecting block 13 and the limiting block 15 upward to complete the secondary limiting. 5. The outer wall is slidably connected to the inner wall of the fixed seat 3 10. The inner wall of the fixed seat 3 10 is provided with a limiting component, which includes a connecting block 2 16, a connecting rod 1 17 and a connecting block 3 18. The outer wall of the connecting block 2 16 is fixedly connected to the inner wall of the fixed seat 3 10. The outer wall of the connecting rod 1 17 is fixedly connected to the inner wall of the connecting block 2 16. The inner wall of the connecting block 3 18 is rotatably connected to the outer wall of the connecting rod 1 17. Under the action of the bolt 19, the connecting block 3 18 is restricted from rotating around the connecting rod 1 17 as the axis, thus completing the initial limiting of the cathode roller body 6. The inner wall of the fixed seat 2 9 is threaded with a bolt 19. One end of the bolt 19 is fixedly connected to a connecting block 4 20.

[0020] Reference Figures 1-6A sliding block 11 is fixedly connected to the lower surface of the fixed seat 3 10. The sliding block 11 moves along the sliding groove in the connecting plate 1, pushing the fixed seat 3 10 closer to the fixed seat 2 9, thereby clamping the cathode roller body 6. The outer wall of the sliding block 11 is slidably connected to the inner wall of the connecting plate 1. A base 12 is fixedly connected to the lower surface of the connecting plate 1. A buffer block 33 is fixedly connected to the outer wall of the base 12. The buffer block 33 is installed on the base 12 to absorb vibrations from below, reduce the impact of vibrations on measurement accuracy, and provide basic vibration damping for the device. A fixed block 21 and the connecting seat 1 28 are fixedly connected to the lower surface of the base 12. A rotating block 22 is rotatably connected to the inner wall of the fixed block 21. Under the constraint of the fixed block 21, the rotating block 22 drives the connecting rod 23 and the rotating block 26 to slide, compressing the spring 25 to achieve buffering. A connecting rod 23 is rotatably connected. A fixing block 34 is fixedly connected to the outer wall of the connecting rod 23. A spring 25 is fixedly connected to the lower surface of the fixing block 34. When the spring 25 is compressed, it absorbs vibration energy and buffers external impact through elastic deformation to ensure measurement stability. A connecting plate 22 is fixedly connected to one end of the spring 25. A rotating block 26 is rotatably connected to the outer wall of the connecting rod 23. A fixing seat 4 27 is rotatably connected to the outer wall of the rotating block 26. The lower surface of the fixing seat 4 27 is fixedly connected to the upper surface of the connecting plate 22. A connecting seat 21 is fixedly connected to the upper surface of the connecting plate 22. The connecting seat 21 cooperates with the connecting seat 1 28 to compress the spring 30 and work together to complete the horizontal vibration buffering. A spring 30 is fixedly connected to the outer wall of the connecting seat 21. A fixing block 4 29 is slidably connected to the outer walls of both the connecting seat 21 and the connecting seat 1 28.

[0021] Working principle: When the cathode roller is tested using an error measuring device, one end of the cathode roller body 6 is first inserted into the sleeve 5 of the fixed seat 4 to achieve initial positioning. Then, the sliding block 11 at the other end slides along the sliding groove of the connecting plate 1, pushing the fixed seat 3 10 toward the fixed seat 2 9 until the other end of the cathode roller body 6 is firmly clamped. Next, the connecting block 4 20 is rotated, causing the bolt 19 to rotate within the fixed seat 2 9, thus restricting the rotation of the connecting block 3 18 around the connecting rod 17, completing the initial positioning. To further fix the cathode roller, the connecting block 13 is pressed, causing the limiting block 15 to slide vertically within the fixed seat 2 9 and the fixed seat 3 10. As the fixed seat 3 10 moves closer to the fixed seat 2 9 under the action of the sliding block 11, the limiting block 15 is embedded into the fixed seat 2 9. At this point, the connecting block 13 is released, and the compressed spring 14 releases its elastic potential energy, pushing the connecting block 13 and the limiting block 15 upwards synchronously. This causes the limiting block 15 to engage in the sliding groove of the fixing seat 9, forming a double limiting mechanism. This achieves rapid and stable installation of the cathode roller, significantly improving assembly efficiency. After fixing, the motor 3 on the fixing block 2 starts, driving the sleeve 5 to rotate, which in turn drives the cathode roller body 6 to rotate. Simultaneously, the measuring instrument 7 mounted on the support frame 8 begins to work, monitoring the operating error of the cathode roller in real time. Notably, the support frame 8 can slide along the connecting plate 1, facilitating multi-point measurement at different locations to ensure accurate inspection. To ensure the comprehensiveness of the measurement results and reduce the impact of vibration on measurement accuracy, the device adopts a multi-buffered design. The buffer block 33 on the base 12 can absorb vibrations from below. When the connecting seat 1 28 slides down inside the fixed block 4 29, it cooperates with the connecting seat 2 31 to compress the spring 3 30, which plays a secondary buffering role. The fixed blocks 2 21 on both sides drive the connecting rod 2 23 and the rotating block 2 26 to slide through the rotating block 1 22, so that the fixed block 3 24 compresses the spring 2 25, further weakening vibration interference. The fixed seat 4 27 and the connecting plate 2 32 work together to ensure that the spring 2 25 is always in an effective buffering state, providing a stable environment for high-precision measurement.
