Description

Technical Field

[0001] This utility model mainly relates to the field of foil making machine technology, specifically a closed-loop control mechanism based on foil making machine. Background Technology

[0002] In the electrolytic copper foil production process, the foil-making machine is a core piece of equipment, and its operational stability and control precision directly affect the production quality and efficiency of copper foil. With the increasing demands from the electronics and information industry for copper foil surface quality, thickness uniformity, and other indicators, the technological upgrading of foil-making machines is urgently needed.

[0003] Traditional foil-making machines have their drive end located at the center of the roller system. This structure causes tiny fluctuations at the center to be amplified at the edge of the roller system with linear velocity, resulting in significant fluctuations in the foil output speed at the edge. This leads to quality defects such as uneven copper foil thickness and surface wrinkles. In addition, the mechanical fluctuations generated by the cycloidal pinwheel reducer commonly used in foil-making machines during operation further exacerbate the instability of the roller system. These problems not only limit the production efficiency of foil-making machines but also increase production costs. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. It mainly provides a closed-loop control mechanism based on a foil-making machine to solve the technical problems mentioned in the background, such as the traditional foil-making machine having its drive end located at the center of the roller system, causing the center fluctuation to be amplified at the edge, resulting in edge foil output speed fluctuations and copper foil quality defects; in addition, the mechanical fluctuations generated by the cycloidal pinwheel reducer exacerbate the instability of the roller system, restricting production efficiency and increasing costs.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A closed-loop control mechanism based on a foil-making machine includes a titanium roller shaft and a support. A large gear is installed at one end of the titanium roller shaft. A T-shaped plate is installed at the front end of the support via a fixing plate. An mounting plate is provided on the outer wall of the T-shaped plate. A closed-loop servo device is provided at the front end of the mounting plate, and a small gear is installed at the input end of the closed-loop servo device. The large gear and the small gear are meshed together.

[0007] More preferably, the outer wall of the titanium roller is fitted with a copper ring, and the rear end of the bracket is provided with a protective cover, which protects the copper ring.

[0008] More preferably, the front end of the bracket is fitted with a housing, the top and bottom of the outer wall of the housing are provided with pipes, a temperature sensor is installed inside the housing, and a cover plate is fitted at the front end of the housing.

[0009] More preferably, the outer wall of the cover plate has a circular hole with an inner diameter larger than the outer diameter of the pinion, and a rubber hose is fitted around the circular hole, one end of which is connected to the mounting plate.

[0010] More preferably, the T-shaped plate has multiple round holes, and the mounting plate has corresponding elliptical holes that match the round holes, and the bolts pass through the round holes of the T-shaped plate and the elliptical holes of the mounting plate to achieve connection.

[0011] More preferably, the pinion and the gear mesh and drive each other, with their tooth profiles matching to ensure no meshing clearance.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This closed-loop control mechanism, through a large gear, a small gear, and a closed-loop servo device, forms a linkage system with the large and small gears during the operation of the mechanism. At the same time, the housing and protective cover constitute a protective structure, which can not only effectively isolate external impurities, but also create a constant temperature operating environment for the gear transmission system through integrated temperature sensors and cooling devices, ensuring that the large and small gears are always under stable operating conditions.

[0014] The closed-loop servo device has high-precision data acquisition capabilities, which can acquire the linear velocity parameters of the pinion in real time and stably, and convert them into the linear velocity data of the titanium roller shaft through an algorithm. This device, together with the servo amplifier, forms a closed-loop adjustment system, which can quickly identify speed deviations and implement compensation, thereby effectively suppressing the high-frequency jitter phenomenon generated at the edge of the titanium roller shaft and improving the stability of system operation.

[0021] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0023] Please refer to the appendix carefully. Figure 1-3 A closed-loop control mechanism based on a foil-making machine includes a titanium roller shaft 1 and a support 2. A large gear 4 is installed at one end of the titanium roller shaft 1 by screws. A T-shaped plate 8 is fixedly installed at the front end of the support 2 by a fixing plate 5. An mounting plate 9 is installed on the outer wall of the T-shaped plate 8 by screws. A closed-loop servo device 10 is installed through the front end of the mounting plate 9, and a small gear 11 is installed at the input end of the closed-loop servo device 10. The large gear 4 and the small gear 11 are meshed.

[0024] In this embodiment, as Figure 1 and Figure 2 As shown, the outer wall of the titanium roller shaft 1 is fitted with two sets of copper rings 3. Each set of copper rings 3 is composed of two semi-circular copper blocks connected by bolts. A protective cover 7 (which can be U-shaped and made of transparent acrylic material) is fixedly installed at the rear end of the bracket 2. The protective cover 7 can form a protective barrier for the copper rings 3, which can prevent the copper rings 3 from being damaged by accidental collisions during the high-speed rotation of the titanium roller shaft 1. At the same time, it can prevent personnel from accidentally touching the rotating parts and improve the safety of equipment operation.

[0025] In this embodiment, as Figure 1 and Figure 2 As shown, a housing 6 is installed at the front end of the bracket 2. Pipe interfaces are evenly distributed on the top and bottom of its outer wall. A temperature sensor is embedded inside. The housing 6 is rotatably connected to the titanium roller shaft 1 through a sealed bearing. A cover plate 12 is installed at the front end of the housing 6. The pipes at the top and bottom can be used as air inlet pipes or exhaust pipes, respectively. The air inlet pipes and exhaust pipes can be connected to an air cooling device. Through real-time monitoring by the temperature sensor and the linkage with the cooling device, the internal temperature of the housing 6 can be regulated to ensure that a relatively constant operating environment is maintained inside, so that the small gear 11 and the large gear 4 inside the housing 6 can operate stably.

[0026] In this embodiment, as Figure 1 and Figure 2 As shown, a circular hole is opened on the surface of the cover plate 12, the inner diameter of which is larger than the outer diameter of the pinion 11, providing adjustment space for the position adjustment and angle calibration of the pinion 11. A rubber hose 13 (made of oil-resistant fluororubber material) is tightly fitted around the circular hole. The two ends of the rubber hose 13 are fastened to the mounting plate 9 and the cover plate 12 by stainless steel clamps to form a sealed structure, which can prevent dust, debris and other impurities from entering the interior of the housing 6.

[0027] In this embodiment, as Figure 1 and Figure 2 As shown, multiple round holes are opened on the surface of the T-shaped plate 8. Correspondingly, two oval holes with matching shapes are opened on the mounting plate 9. The bolts are passed through the round holes of the T-shaped plate 8 and the oval holes of the mounting plate 9 in sequence to achieve a stable connection between the two. This hole combination design provides flexible space for fine adjustment during the installation process. The position of the components can be calibrated according to the actual working conditions, improving the adaptability of equipment assembly.

[0028] In this embodiment, as Figure 3 As shown, the pinion 11 and the gear 4 use involute tooth profile meshing transmission, and the tooth profile curvature of the two are precisely matched to eliminate meshing gaps during transmission, ensuring the smoothness and accuracy of power transmission.

[0029] The specific operating procedure of this utility is as follows: The titanium roller shaft 1 is securely installed on the machine body. When the drive device (such as a servo motor) on the machine body is started, the titanium roller shaft 1 is driven to rotate. The copper ring 3 and the large gear 4, which are fixed on the titanium roller shaft 1 by interference fit, rotate synchronously.

[0030] The large gear 4 and the small gear 11 form a gear transmission. When the large gear 4 rotates, it drives the small gear 11 to rotate through the meshing force between the teeth. In this transmission process, the closed-loop servo device 10 plays a key role. The device is coaxially connected to the small gear 11 through a high-precision encoder and collects the linear velocity data of the small gear 11 in real time at a sampling frequency of thousands of times per second. Since there is a precise transmission ratio relationship between the small gear 11 and the titanium roller shaft 1, the linear velocity data of the small gear 11 can be converted into the actual linear velocity of the titanium roller shaft 1 through calculation, thereby providing a more accurate feedback on the operating status of the titanium roller shaft 1.

[0031] Meanwhile, the temperature sensor inside the housing 6 uses thermocouple or thermistor technology to sense the temperature changes inside the housing 6 in real time and transmits the data to the central control system of the equipment with a millisecond response speed. When the internal temperature exceeds the preset threshold, the central control system immediately triggers the air cooling device to start. This device forms an air circulation system with the help of an axial flow fan. First, hot air is drawn from inside the housing 6. After heat exchange treatment by the cooling module, the cooled air is reintroduced into the housing 6. Through continuous air convection, the housing 6 is efficiently cooled, and the internal temperature is brought back to a safe range. This avoids problems such as decreased lubricating oil viscosity and thermal expansion and deformation of parts caused by high temperature, and ensures that the transmission system operates stably in a suitable temperature environment.

[0032] The real-time linear velocity data acquired by the closed-loop servo device 10 is immediately fed back to the servo amplifier. The servo amplifier has a built-in digital signal processing chip that performs Fast Fourier Transform (FFT) analysis on the received data to accurately identify the fluctuation characteristics of the linear velocity of the titanium roller shaft 1 in the time and frequency domains, especially the high-frequency jitter signal at the edge. Based on these analysis results, the servo amplifier adjusts the output waveform of the drive device in real time through pulse width modulation (PWM) technology to dynamically compensate for speed deviation. For example, when speed fluctuations are detected at the edge of the titanium roller shaft 1, the servo amplifier increases the output torque of the drive device to offset the effects of external load changes or mechanical wear, so that the linear velocity of the titanium roller shaft 1 is always kept within the set stable value range, thereby effectively reducing fluctuations at the edge and ultimately eliminating jitter.

[0033] By combining mechanical transmission and electronic control, a closed-loop feedback regulation mechanism is constructed to ensure that the titanium roller 1 maintains stable operation during high-speed operation.

[0034] It should be noted that the linkage structure of the air cooling device, axial fan and temperature sensor involved in this utility model is a mature existing technology. The specific linkage method, control system and structural details will not be described in detail. The closed-loop servo device 10, servo amplifier and body drive device referenced in this embodiment are implemented using mature industry standard technologies in their mechanical structure and control system. The specific technical details of their internal circuit design, signal processing algorithm, power drive unit and other aspects are mature technologies in related fields and are not the innovative protection content of this solution. Therefore, they will not be described in detail.

[0035] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
