Description

Technical Field

[0001] The invention relates to the technical field of copper foil production, and in particular to an online monitoring device for the glossiness of copper foil. Background Art

[0002] Copper foil can be divided into electrolytic copper foil and rolled copper foil. Electrolytic raw foil is an important process in the production of electrolytic copper foil. In the electrolytic cell, the electrolyte is reduced and deposited on the surface of the cathode roller by direct current to form copper foil. This process includes continuous rotation of the cathode roller, pickling, washing, drying, peeling and other processes, and finally forms a roll of raw foil. In the production process of electrolytic copper foil, the glossiness of copper foil is not only a reflection of its appearance quality, but also a key indicator of its production process control, quality control and performance evaluation. The glossiness detection can be achieved by manually collecting the glossiness data of the rough surface of the electrolytic copper foil, so as to obtain the glossiness change trend and deviation value. Through the change of glossiness, the process adjustment personnel can complete the adjustment of the current value and the amount of additives added in the production process of the electrolytic copper foil, and realize the adjustment of the production process. The implementation of this method can maximize the consistency of electrolytic copper foil, reduce defects such as foil surface flower and color difference, and avoid degradation or scrapping due to quality problems.

[0003] The current gloss measurement method is manual measurement. Before starting the test, the gloss meter is calibrated to ensure its accuracy and reliability. After the calibration is completed, the process personnel hold the gloss meter and put the instrument measurement port close to the rough surface of the copper foil. The gloss value is displayed at this time. Manual measurement is a single measurement, and the value only shows a single result. Risk points of manual measurement: ① Manual measurement is measured at the cathode roller. When measuring, you need to step up and down the pedal. First, there is a safety risk. Second, foreign matter will be brought into the foil surface to form concave and convex points, causing product degradation. ② During manual measurement, the instrument contacts the foil surface. On the one hand, because the foil itself is extremely thin, improper operation will scratch the foil surface or even puncture the foil surface, causing the product to be scrapped. On the other hand, excessive force will damage the cathode roller. The surface of the cathode roller is made of precious metal materials, and the repair cost after collision is high. Summary of the invention

[0004] The technical solution of the present invention aims at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology. An embodiment of the present invention provides an online monitoring device for the glossiness of copper foil to solve the technical problem that the existing copper foil glossiness is not convenient for real-time monitoring.

[0005] The embodiment of the present invention adopts the following technical solution: it includes two connecting frames, wherein the connecting frames are provided with a transition roller and a winding shaft for the copper foil to pass through, and also includes an online monitoring mechanism, wherein the online monitoring mechanism includes a movable frame, wherein the movable frame is provided with an electric-controlled telescopic frame, wherein the movable frame is connected to one of the connecting frames, wherein one side of the end of the electric-controlled telescopic frame is connected to a gloss detector, and the other side is connected to an electrical property detector, wherein two electromagnetic coils are provided on the side of the transition roller via a mounting frame, and wherein a display is provided on the movable frame.

[0006] Furthermore, the two electromagnetic coils are arranged opposite to each other, and the two electromagnetic coils are respectively located on the inner and outer sides of the copper foil, and the electromagnetic coils are movably connected to the mounting frame.

[0007] Furthermore, there is a gap between the two electromagnetic coils and the copper foil.

[0008] Furthermore, the gloss detector does not contact the copper foil.

[0009] Furthermore, the electrical property detector is electrically connected to the display and the electrically controlled telescopic rod respectively.

[0010] Furthermore, the electrical property detector does not contact the copper foil.

[0011] Compared with the prior art, the beneficial effects of the present invention are: First, 1. The invention patent realizes real-time monitoring of glossiness by designing an online monitoring device: The advantages are: ① The detection method is non-contact, and the probe is 5-10mm away from the foil surface; (Due to the non-contact method, the copper foil produced is thinner. At this time, the detector does not contact the copper foil, which can effectively avoid being detected and causing the copper foil to tear); ② The detection equipment can be returned when not in use (telescopic structure), which will not affect the roll-down and equipment maintenance; ③ The detection data is presented on the existing rectifier cabinet display, realizing real-time data display and historical data export functions; ④ Fixed position single-point gloss detection, the measurement time interval can be set by yourself (0-9999s); Secondly, when in use, through the online monitoring mechanism, during the detection process, due to the reduction of the electrolyte content or other factors, the copper foil becomes uneven in thickness. When passing through the transition roller, the copper foil will warp, but the warping deformation at this place may be small. When the copper foil surface is detected by the gloss detector, the gloss detector uses the reflection of light to determine whether the surface gloss of the copper foil is qualified. When the warped copper foil passes through the gloss detector, the distance between the warped copper foil and the gloss detector changes, resulting in detection errors when using light reflection for detection. At the same time, when the detection error occurs, it is not known whether it is due to the gloss temperature or the temperature at which the copper foil warps. Through the online detection mechanism, when the warping phenomenon occurs, the position of the gloss detector will change synchronously, so that there can be a gap between the gloss detector and the copper foil to ensure the detection accuracy. At the same time, the electrical monitor and the electromagnetic coil can be used to determine whether the copper foil has warped, which is convenient for making different appearance methods for different production problems to ensure the production of copper foil. In summary, the existing manual inspection method of copper foil by the detector is changed to real-time non-contact. Firstly, it reduces the problem of people having to go up and down frequently. Secondly, the non-contact method can effectively avoid the problem of copper foil tearing due to the contact and squeezing of the detector during the inspection. Secondly, the online monitoring mechanism can determine whether the copper foil is warped or has different glossiness problems, so that different treatment methods can be used for different problems. Secondly, it can also avoid the phenomenon of inaccurate glossiness detection data caused by warping. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] Combine the following Figures 1 to 6As shown, an embodiment of the present invention provides an online monitoring device for the glossiness of copper foil, comprising two connecting frames 1, wherein the connecting frames 1 are provided with a winding shaft 2 and a transition roller 3 for the copper foil to pass through, and further comprising an online monitoring mechanism 4, wherein the online monitoring mechanism 4 comprises a movable frame 41, wherein the movable frame 41 is provided with an electric-controlled telescopic frame 45, wherein the movable frame 41 is connected to one of the connecting frames 1, wherein one side of the end of the electric-controlled telescopic frame 45 is connected to a glossiness detector 42, and the other side is connected to an electrical property detector, two electromagnetic coils 46 are provided on the side of the transition roller 3 through a mounting frame 44, and a display is provided on the movable frame 41.

[0021] During operation, the existing manual inspection method of the copper foil by the detector is changed to a real-time non-contact method. Firstly, the problem of people having to go up and down frequently is reduced. Secondly, the non-contact method can effectively avoid the problem of the copper foil being torn due to the contact and squeezing of the copper foil by the detector during the inspection. Secondly, the online monitoring mechanism 4 can determine whether the copper foil is warped or has different glossiness problems, so that different treatment methods can be used for different problems. Secondly, the phenomenon of inaccurate glossiness detection data caused by warping can be avoided.

[0022] Specifically, the two electromagnetic coils 46 are arranged opposite to each other, and the two electromagnetic coils 46 are respectively located on the inner and outer sides of the copper foil, and the electromagnetic coils 46 are movably connected to the mounting frame 44 .

[0023] During operation, the copper foil may warp, that is, it may warp outward or inward. Therefore, the two electromagnetic coils 46 can detect the copper foils in different warping directions.

[0024] Specifically, there is a gap between the two electromagnetic coils 46 and the copper foil.

[0025] During operation, if the electromagnetic coil 46 does not contact the copper foil, the copper foil will not bend outwards, and the copper foil will not enter the electromagnetic coil 46 to cut the magnetic flux lines.

[0026] Specifically, the gloss detector 42 does not contact the copper foil.

[0027] When working, a non-contact detection method is adopted to avoid contact between the detector and the copper foil, which causes squeezing force on the copper foil and causes the copper foil to tear.

[0028] Specifically, the electrical property detector is electrically connected to the display and the electrically controlled telescopic rod respectively.

[0029] Specifically, the electrical property detector does not contact the copper foil.

[0030] When working, the electrical property detector adopts a Hall effect sensor or a contact electrical property detector. Under the action of the electromagnetic coil 46, a magnetic field will exist inside the electromagnetic coil 46. When the warped copper foil passes through the magnetic field, a voltage difference will appear on both sides of the conductor in the direction perpendicular to the current and the direction of the magnetic field current. The Hall effect sensor is used to detect the voltage difference. If a voltage difference appears, it indicates that the copper foil is warped.

[0031] If a contact detector is used, when the copper foil passes through the magnetic field coil, the copper foil will cut the coil, causing the copper foil to be charged. At this time, the contact detector can determine whether the copper foil is charged because it is in contact with the copper foil, and then determine whether the copper foil is warped based on whether the copper foil is charged.

[0032] Working principle: When in use, first set the distance between the gloss tester 42 and the copper foil according to the needs, and then set the detection gap of the gloss tester 42. At this time, the copper foil led out by the cathode roller is led out through the winding shaft 2 and the transition roller 3 in the connecting frame 1. During the leading-out process, it will first pass through the electromagnetic coil 46. When passing through the electromagnetic coil 46, the inner diameter of the electromagnetic coil 46 is charged. When the copper foil does not warp, the copper foil will be transported normally, and then the glossiness of the copper foil surface will be detected by the gloss tester 42 (gloss tester 4 The principle of 2 is based on optical measurement technology. It mainly determines the glossiness of the material by measuring the reflection of light on the surface of the sample). The detected results are then reflected on the rectifier cabinet display to realize real-time data display and historical data export functions. Due to the reduction of the electrolyte content of the copper foil or other factors that cause the copper foil to be uneven in thickness, the copper foil will warp when passing through the transition roller 3. However, the warping deformation at this location may be small, and the warped copper foil will bulge, causing part of the copper foil to enter the magnetic induction coil and cut the magnetic flux lines (when warping, Since the inner surface of the copper foil is in contact with the transition roller 3, under the action of the transition roller 3, it is difficult for the copper foil to bend sideways toward the transition roller 3, so the warping direction of the copper foil is relatively single, that is, it is warped outward). After cutting the magnetic flux lines, the copper foil will be charged. At this time, the electrical property monitor 43 can be used to detect whether the copper foil is charged. If the copper foil is charged, a signal will be generated first, causing the electric control telescopic rod to move to avoid contact between the copper foil and the gloss detector 42, thereby ensuring that a gap is always maintained between the copper foil and the gloss detector 42. Secondly, the electrical property monitor 43 will also generate a signal. Send a signal to the display. If the glossiness detector 42 changes due to the warping phenomenon, it means that the data is affected by other factors. If the data reflected by the glossiness detector 42 always changes, it can be concluded that there is a problem with the glossiness of the copper foil (the process adjustment personnel need to adjust the current value and the amount of additives added in the electrolytic copper foil production process according to the changes). If the electrical property detector always sends a signal, it means that there is a problem with the copper foil produced during this period, and it is necessary to pay attention to the electrolyte content or other factors that may affect the warping phenomenon (such as fluctuations in the electrolytic roller current). In summary, the existing manual inspection method of copper foil by the detector is changed to real-time non-contact. Firstly, it reduces the problem of people having to go up and down frequently. Secondly, the non-contact method can effectively avoid the problem of copper foil being torn due to the contact and squeezing of the detector during the inspection. Secondly, the online monitoring mechanism 4 can determine whether the copper foil is warped or has different glossiness problems, so that different treatment methods can be used for different problems. Secondly, it can also avoid the phenomenon of inaccurate glossiness detection data caused by warping.
