Description
Technical Field
[0001] This invention relates to the field of single-sided panel production technology, specifically a high-temperature lamination device for producing double-layer single-sided panels. Background Technology
[0002] Existing high-temperature lamination equipment for single and double-sided boards without adhesive, such as CN207028385U, produces only one set of boards at a time. Lamination, peeling, and winding are performed at separate stations, and there is no online peeling and winding structure. After the boards are laminated and stacked, they need to be transferred to the next process for secondary processing, which is cumbersome. In addition, the following problems exist: First, there is a temperature difference between the middle and the edge of the laminated board, which causes uneven melting of TPI, resulting in glue overflow or poor bonding. Second, it is impossible to adaptively adjust the lamination pressure according to the melting state of TPI, and it relies solely on manual sampling, which results in delayed feedback and high losses. Third, the copper foil is prone to warping and uneven tension before lamination, which leads to wrinkles and defects such as bubbles after lamination. Fourth, it cannot be rolled in layers by machine, which not only results in low production capacity, but also makes it impossible to check for glue defects on the laminated boards in a timely manner, making quality control difficult.
[0003] Traditional equipment can no longer meet the requirements of high-quality, large-scale production. Therefore, it is necessary to develop a new type of high-temperature pressing equipment that integrates temperature uniformity, pressure regulation, flattening and anti-warping, and online peeling and winding. Summary of the Invention
[0004] The technical problem to be solved by the present invention is the issues of uniform melting, melt degree detection, copper foil flattening and finished product layering and winding in the production process of single-layer panels. The invention provides a high-temperature lamination device for producing double-layer single-layer panels.
[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A high-temperature pressing device for producing double-layer single-sided panels includes a feeding unit, a controller on the feeding unit, a pressing unit on one side of the feeding unit, and a receiving and peeling unit on one side of the pressing unit. The feeding unit includes a feeding component and a mounting plate; The pressing unit includes temperature difference elimination components, flattening components, anti-warping components, testing components, and pressing components; The receiving and peeling unit includes a film receiving component, a peeling component, and a receiving component; The temperature difference elimination component, anti-warping component, detection component, and pressing component are all mounted on the mounting plate, as are the film receiving component, peeling component, and material receiving component. In existing single-sided panel production processes, problems such as uneven melting, inability to detect melt density, and copper foil warping and wrinkling exist. This invention eliminates the temperature difference between the center and edge of the heating plate using the temperature difference elimination component. The detection component detects the melt density of the molten TPI and adaptively adjusts the heating temperature of the heating plate based on the test results. Simultaneously, it adjusts the pressing force for subsequent pressing of the molten TPI that has not yet reached its optimal melting state, i.e., adjusting the pressing spacing of the pressing components to avoid overflow and insufficient pressing force. The flattening component flattens the delivered copper foil to prevent wrinkles, and the anti-warping component adaptively presses the edges of copper foils of different sizes to prevent warping and avoid defects such as bubbles during subsequent pressing.
[0006] Furthermore, the temperature difference mitigation component includes a pressing plate, a heat-conducting plate, a heat-conducting block, a heat-conducting bridge, a bent rod, and a heat transfer plate. The pressing plate is connected to the mounting plate via an electric push rod. A heating plate is mounted on the pressing plate, with a heat-conducting plate at its center. A heat-conducting block, made of an alloy material that expands with heat, is mounted on the heat-conducting plate. The heat-conducting block abuts against one end of the heat-conducting bridge. The heat-conducting bridge is rotatably connected to the bent rod, which is fixedly connected to the pressing plate. The heat transfer plate is positioned at the edge of the heating plate, and the other end of the heat-conducting bridge is located above the heat transfer plate. In existing technologies, heating plates often heat up quickly in the center and slowly at the edges, resulting in uneven melting of TPI. This invention utilizes the thermal expansion characteristic of the heat-conducting block. When the temperature at the center of the heating plate is too high, the heat-conducting block expands and pushes up the heat-conducting bridge. The heat-conducting bridge rotates around its fulcrum, transferring excess heat from the center to the heat transfer plate at the edge through the other end of the bridge. This automatically compensates for the heat in the center to the edge, ensuring a uniform temperature across the entire surface of the heating plate.
[0007] Furthermore, the flattening component includes a flattening roller and spiral ridges. The outer surface of the flattening roller is provided with spiral ridges, and the diameter of the flattening roller decreases from the middle to both sides. In the prior art, copper foil often has curling and tiny wrinkles after being released from the roll. The present invention uses an arc-shaped flattening roller that is thicker in the middle and thinner at both ends, in conjunction with the spiral ridges on the surface, to generate a radial force that spreads outwards as the copper foil passes through, pushing the copper foil flat from the middle to both sides, so that the copper foil enters the pressing zone flat and wrinkle-free.
[0008] Furthermore, there are two sets of spiral protrusions, which are symmetrically installed on the flattening roller.
[0009] Furthermore, the anti-warping component includes a round rod, a fixed plate, an electric telescopic rod, a pressure roller, and a photoresistor. The round rod is rotatably connected to the flattening roller, and the round rod is fixedly connected to the fixed plate. The fixed plate is fixedly connected to the mounting plate. The output end of the electric telescopic rod is rotatably connected to the pressure roller, and the fixed end of the electric telescopic rod is fixedly connected to the fixed plate. An annular groove is formed on the pressure roller, and a photoresistor is installed in the annular groove. A light source is installed on the fixed plate located below the photoresistor. In the prior art, the edge of the copper foil is prone to warping upwards during transportation, causing the warping problem. This invention utilizes the fact that the area of the photoresistor blocked varies with the width of the copper foil, causing a change in resistance value. This automatically controls the extension and retraction of the electric telescopic rod, ensuring that the pressure roller presses precisely on the edge of the copper foil, achieving adaptive edge pressing and anti-warping for copper foil of different specifications.
[0010] Furthermore, the detection components include a detection roller, a spiral spring, a crossbar, a conductive block, an arc-shaped rod, and a fixed cylinder. The detection roller is rotatably connected to the fixed cylinder via a smooth rod. The fixed cylinder is fixedly mounted on a mounting plate. One end of the spiral spring is fixedly connected to the smooth rod, and the other end is fixedly connected to the inner wall of the fixed cylinder. The smooth rod is fixedly connected to the crossbar, and a conductive block is mounted on the crossbar. The conductive block is slidably connected to the arc-shaped rod, and the arc-shaped rod is fixedly connected to the fixed cylinder. In existing technologies, the degree of TPI melting cannot be detected online. This invention utilizes the fact that the different viscosities of TPI after melting result in different resistances on the detection roller. This alters the sliding distance of the conductive block on the arc-shaped rod, thereby converting the degree of melting into an electrical signal, achieving real-time online detection of the TPI melting degree.
[0011] Furthermore, a conductive coil is installed on the arc-shaped rod, with the end of the conductive coil near the pressing plate serving as the current input terminal.
[0012] Furthermore, the pressing component includes a double-headed electrically telescopic rod, a copper foil pressure roller, and a protective film pressure roller. A conductive block is electrically connected to the double-headed electrically telescopic rod. The fixed end of the double-headed electrically telescopic rod is fixedly mounted on a mounting plate. The telescopic ends of the double-headed electrically telescopic rod are connected to the copper foil pressure roller via smooth rods, and the telescopic ends of the double-headed electrically telescopic rod are connected to the protective film pressure roller via smooth rods. The copper foil pressure roller and the smooth rod are rotatably connected, and the protective film pressure roller and the smooth rod are rotatably connected. In the prior art, the pressing force is fixed and constant. If the initial melting is insufficient, the subsequent melting cannot be remedied. This invention directly controls the telescopic length of the double-headed electrically telescopic rod through the position signal of the conductive block, achieving real-time adaptive adjustment of the pressing gap and pressure according to the actual melting state.
[0013] Furthermore, the film receiving component includes a film peeling roller and a film receiving roller. The film peeling roller is connected to the mounting plate via a drive motor, and the film receiving roller is connected to the mounting plate via a drive motor.
[0014] Furthermore, the peeling component includes a tension detector and a peeling module, with the tension detector fixedly mounted on the mounting plate and the peeling module fixedly mounted on the mounting plate.
[0015] Furthermore, the take-up component includes an lead-out wheel and a take-up roller. The lead-out wheel is rotatably mounted on the mounting plate, and the take-up roller is connected to the mounting plate via a drive motor.
[0016] Furthermore, the feeding components include a protective film feeding roller, a copper foil feeding roller, and a TPI feeding roller. The protective film feeding roller is connected to the mounting plate via a drive motor, the copper foil feeding roller is connected to the mounting plate via a drive motor, and the TPI feeding roller is connected to the mounting plate via a drive motor.
[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention features a heat-conducting plate in the central area of the heating plate, where the temperature is relatively high. Heat is rapidly transferred through the heat-conducting plate to the heat-conducting block in contact with it. After absorbing heat, the heat-conducting block expands in volume, causing the heat-conducting bridge to rotate around the bent rod as a fulcrum. This transfers excess heat from the central area to the heat transfer plate at the edge of the heating plate, thus supplementing the heating of the edge area and eliminating the temperature difference between the center and edge of the heating plate. This avoids the problem of local over-melting or insufficient melting of TPI material during the pressing process.
[0018] 2. In this invention, if the TPI material is over-melted or under-melted, its surface viscosity changes, causing a corresponding change in the frictional force on the detection roller surface. The spiral spring releases or contracts, driving the rotating shaft of the detection roller to rotate, causing the conductive block to slide on the arc-shaped rod. As the conductive block slides, the current supplied by the conductive coil to the double-headed electric telescopic rod changes, adaptively changing the elongation of the double-headed electric telescopic rod, and adjusting the pressing gap between the copper foil pressure roller and the protective film pressure roller. This avoids overflow problems caused by over-melted TPI material due to excessive pressure and quality problems such as poor pressing and delamination caused by insufficient pressure.
[0019] 3. When the copper foil drives the flattening roller to rotate, the spiral ridges generate an axial force on the copper foil, continuously pushing the copper foil from the middle to both sides. Due to the arched structure formed by the decreasing diameter of the flattening roller surface from the middle to both sides, the tension in the middle of the copper foil is greater than that in the edge area, forming a natural lateral tension gradient, which further promotes the automatic flattening of the copper foil during the conveying process, effectively eliminating wrinkle defects. In order to avoid the copper foil from warping, the controller controls the electric telescopic rod to extend downward. The controller locks the extension length of the electric telescopic rod by detecting the light intensity through the photoresistor, so that the pressure roller presses the edge at a fixed length to prevent edge warping.
[0020] 4. This invention separates the two composite single-layer panels by having the sheet material enter the peeling module for layering. The separated single-layer panels are guided into their respective conveying paths by lead-out wheels and are finally independently wound up by multiple sets of winding rollers. This online peeling and layered winding design eliminates the need for subsequent secondary peeling processing. Attached Figure Description

[0023] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0024] like Figure 1 , Figure 2 As shown in Embodiment 1 of the present invention, a technical solution for a high-temperature lamination device for producing double-layer single-sided panels is provided.
[0025] The specific content of Embodiment 1 is as follows: A high-temperature pressing equipment for producing double-layer single-sided panels includes a feeding unit 1, a controller is provided on the feeding unit 1, a pressing unit 2 is provided on one side of the feeding unit 1, and a receiving and peeling unit 3 is provided on one side of the pressing unit 2. The feeding unit 1 includes a feeding component 11 and a mounting plate 12; The pressing unit 2 includes a temperature difference elimination component 21, a flattening component 22, an anti-warping component 23, a detection component 24, and a pressing component 25; The receiving and peeling unit 3 includes a film receiving component 31, a peeling component 32, and a receiving component 33; Temperature difference elimination component 21, anti-warping component 23, detection component 24 and pressing component 25 are all mounted on mounting plate 12, and film receiving component 31, peeling component 32 and material receiving component 33 are all mounted on mounting plate 12.
[0026] After the TPI is fed from the feeding unit 1 to the pressing unit 2 for pressing, the copper foil is fed to the pressing unit 2 and pressed with the TPI. Then the protective film is fed to the panel after the copper foil and TPI are pressed together for pressing again. After successful pressing, the protective film is removed and then the panel is wound up by the take-up peeling unit 3, thus completing the production of a single panel.
[0027] like Figures 3-9 As shown, in Embodiment 2 of the present invention, the pressing unit 2 in Embodiment 1 is optimized. After the temperature difference between the middle and the edge of the heating plate is eliminated by the temperature difference elimination component 21, the detection component 24 detects the melt degree of the molten TPI, thereby adaptively adjusting the heating temperature of the heating plate. At the same time, the pressing force of the subsequent pressing of the molten TPI that has not reached the optimal melting state is adjusted, that is, the pressing spacing of the pressing component 25 is adjusted to avoid the problems of overflow and insufficient pressing force. The flattening component 22 flattens the copper foil that is fed in to avoid wrinkles. In conjunction with the anti-warping component 23, the copper foil of different sizes is adaptively pressed to prevent warping and avoid defects such as bubbles in the subsequent pressing.
[0028] The specific content of Embodiment 2 is as follows: The temperature difference elimination component 21 includes a pressing plate 211, a heat-conducting plate 212, a heat-conducting block 213, a heat-conducting bridge 214, a bent rod 215, and a heat transfer plate 216. The pressing plate 211 is connected to the mounting plate 12 via an electric push rod. A heating plate is provided on the pressing plate 211, and a heat-conducting plate 212 is provided at the center of the heating plate. A heat-conducting block 213 is provided on the heat-conducting plate 212. The heat-conducting block 213 is made of an alloy material that expands under heat (e.g., a high-expansion alloy based on iron and nickel). One end of the heat-conducting block 213 abuts against the heat-conducting bridge 214. The heat-conducting bridge 214 is rotatably connected to the bent rod 215. The bent rod 215 is fixedly connected to the pressing plate 211. The heat transfer plate 216 is located at the edge of the heating plate, and the other end of the heat-conducting bridge 214 is located above the heat transfer plate 216.
[0029] When the TPI material is conveyed to the pressing plate 211 station, the controller drives the electric push rod to move the upper and lower pressing plates 211 closer together, so that the heating plate applies pressure to the TPI material and performs high-temperature pressing. During the pressing process, since the temperature of the central area of the heating plate is usually higher than that of the edge area, it is easy to cause uneven heating of the TPI material. To solve this temperature difference problem, a heat-conducting plate 212 is set in the central area of the heating plate. The temperature of this area is relatively high. Heat is quickly transferred to the heat-conducting block 213 in contact with it through the heat-conducting plate 212. After absorbing heat, the heat-conducting block 213 expands in volume, which pushes the heat-conducting bridge 214 to rotate around the bent rod 215 as the fulcrum. The excess heat in the central area is transferred to the heat transfer plate 216 in the edge area of the heating plate through the heat-conducting bridge 214, thereby supplementing the heating of the edge area of the heating plate, thus eliminating the temperature difference between the center and the edge of the heating plate, and avoiding the problem of local over-melting or insufficient melting of the TPI material during the pressing process.
[0030] The flattening component 22 includes a flattening roller 221 and a spiral protrusion 222. The outer surface of the flattening roller 221 is provided with a spiral protrusion 222, and the diameter of the flattening roller 221 decreases from the middle to both sides.
[0031] There are two sets of spiral protrusions 222, which are symmetrically installed on the flattening roller 221.
[0032] The anti-tilting component 23 includes a round rod 231, a fixing plate 232, an electric telescopic rod 233, a pressure roller 234, and a photoresistor 235. The round rod 231 is rotatably connected to the flattening roller 221, and the round rod 231 is fixedly connected to the fixing plate 232. The fixing plate 232 is fixedly connected to the mounting plate 12. The output end of the electric telescopic rod 233 is rotatably connected to the pressure roller 234, and the fixed end of the electric telescopic rod 233 is fixedly connected to the fixing plate 232. An annular groove is provided on the pressure roller 234, and a photoresistor 235 is provided on the annular groove of the pressure roller 234. A light source is provided on the fixing plate 232 located below the photoresistor 235.
[0033] During the conveying process, copper foil is prone to wrinkles due to uneven tension distribution, which seriously affects the subsequent pressing quality. Therefore, when the copper foil drives the flattening roller 221 to rotate, the spiral ridge 222 generates an axial force on the copper foil, continuously pushing the copper foil from the middle to both sides. The arched structure formed by the decreasing diameter of the flattening roller 221 from the middle to both sides makes the tension in the middle of the copper foil greater than that in the edge area, forming a natural lateral tension gradient, which further promotes the automatic flattening of the copper foil during the conveying process and effectively eliminates wrinkle defects. In order to avoid the copper foil warping, the controller controls the electric telescopic rod 233 to extend downwards, and at the same time starts the light source to continuously irradiate. The intensity of the photoresistor 235 in the annular groove of the pressure roller 234 changes due to the light source irradiation. After the controller detects the resistance change, it immediately locks the extension length of the electric telescopic rod 233, so that the pressure roller 234 is kept in this position to perform fixed-length edge pressing on the edge of the copper foil and prevent the edge of the copper foil from warping.
[0034] The detection component 24 includes a detection roller 241, a spiral spring 242, a crossbar 243, a conductive block 244, an arc-shaped rod 245, and a fixed cylinder 246. The detection roller 241 is rotatably connected to the fixed cylinder 246 via a smooth rod. The fixed cylinder 246 is fixedly mounted on the mounting plate 12. One end of the spiral spring 242 is fixedly connected to the smooth rod, and the other end of the spiral spring 242 is fixedly connected to the inner wall of the fixed cylinder 246. The smooth rod is fixedly connected to the crossbar 243. A conductive block 244 is provided on the crossbar 243. The conductive block 244 is slidably connected to the arc-shaped rod 245, and the arc-shaped rod 245 is fixedly connected to the fixed cylinder 246.
[0035] A conductive coil is provided on the arc-shaped rod 245, and the end of the conductive coil near the pressing plate 211 is the current input terminal.
[0036] The pressing component 25 includes a double-headed electric telescopic rod 251, a copper foil pressure roller 252, and a protective film pressure roller 253. The conductive block 244 is electrically connected to the double-headed electric telescopic rod 251. The fixed end of the double-headed electric telescopic rod 251 is fixedly installed on the mounting plate 12. The telescopic ends of the double-headed electric telescopic rod 251 are connected to the copper foil pressure roller 252 through a smooth rod. The telescopic ends of the double-headed electric telescopic rod 251 are connected to the protective film pressure roller 253 through a smooth rod. The copper foil pressure roller 252 is rotatably connected to the smooth rod, and the protective film pressure roller 253 is rotatably connected to the smooth rod.
[0037] If the TPI material is over-melted, its surface viscosity decreases, resulting in a corresponding decrease in the frictional force on the roller surface when the material passes through the detection roller 241. At this time, the spiral spring 242 releases its elastic force, causing the rotating shaft of the detection roller 241 to rotate clockwise. Through the transmission action of the smooth rod, the crossbar 243 and the conductive block 244 rotate clockwise synchronously, causing the conductive block 244 to slide on the arc rod 245. As the conductive block 244 slides, the effective length of the conductive coil connected to the circuit on the arc rod 245 decreases, the overall circuit resistance decreases, and the current sent by the controller to the double-headed electric telescopic rod 251 increases accordingly. The increased current causes the double-headed electric telescopic rod 251 to elongate, which increases the pressing gap between the copper foil pressure roller 252 and the protective film pressure roller 253, thereby reducing the pressing pressure and avoiding the overflow problem of over-melted TPI material due to excessive pressure.
[0038] Conversely, if the TPI material is not fully melted, its surface hardness is high, and the frictional force on the roller surface increases accordingly when it passes through the detection roller 241. At this time, the detection roller 241 overcomes the elastic force of the spiral spring 242 and rotates counterclockwise, causing the crossbar 243 and the conductive block 244 to rotate counterclockwise synchronously. The effective length of the conductive coil connected to the circuit increases, the overall resistance of the circuit increases, and the current sent by the controller to the double-headed electric telescopic rod 251 decreases accordingly. The decrease in current shortens the elongation of the double-headed electric telescopic rod 251, which reduces the pressing gap between the pressure rollers, thereby increasing the pressing pressure and avoiding quality problems such as poor pressing and delamination caused by insufficient pressure.
[0039] At the same time, the controller also adjusts the heating power of the heating plate in real time according to the changes in the output current of the conductive coil. When the output current of the conductive coil increases, it indicates that the TPI has a tendency to over-melt, and the controller reduces the power supply current of the heating plate accordingly. When the output current of the conductive coil decreases, it indicates that the TPI has a tendency to under-melt, and the controller increases the power supply current of the heating plate accordingly to ensure that the TPI melts to the optimal melting temperature range.
[0040] like Figure 2 , 10 As shown, in Embodiment 3 of the present invention, the material taking-up peeling unit 3 and the feeding unit 1 in Embodiment 1 are optimized. A TPI feeding roller 113 is added to the feeding unit 1 for pressing the double-layer single-sided panels. A peeling module 322 (wherein, the peeling module 322 can be the peeling corner roller peeling device in the prior art, which is not an improvement of the present invention and will not be described in detail here) and a guide wheel 331 are added to the material taking-up peeling unit 3. After the double-layer pressed glue-free single-sided panels are peeled off by the peeling module 322, the two glue-free single-sided panels are separated and wound up by different paths under the guidance of the guide wheel 331. The appearance quality of the adhesive surface can be inspected during peeling and winding, thereby improving production efficiency.
[0041] The specific content of Embodiment 3 is as follows: The film receiving component 31 includes a film peeling roller 311 and a film receiving roller 312. The film peeling roller 311 is connected to the mounting plate 12 through a drive motor, and the film receiving roller 312 is connected to the mounting plate 12 through a drive motor.
[0042] The peeling component 32 includes a tension detector 321 and a peeling module 322. The tension detector 321 is fixedly mounted on the mounting plate 12, and the peeling module 322 is fixedly mounted on the mounting plate 12.
[0043] The take-up component 33 includes an lead-out wheel 331 and a take-up roller 332. The lead-out wheel 331 is rotatably mounted on the mounting plate 12, and the take-up roller 332 is connected to the mounting plate 12 via a drive motor.
[0044] The feeding component 11 includes a protective film feeding roller 111, a copper foil feeding roller 112, and a TPI feeding roller 113. The protective film feeding roller 111 is connected to the mounting plate 12 via a drive motor, the copper foil feeding roller 112 is connected to the mounting plate 12 via a drive motor, and the TPI feeding roller 113 is connected to the mounting plate 12 via a drive motor.
[0045] By adding additional TPI feeding rollers 113, double-layer single-sided panels can be pressed and formed in one step, significantly improving production efficiency. After pressing, the double-layer single-sided panels are first peeled off completely and wound up by the synergistic action of peeling rollers 311 and take-up rollers 312. After the protective film is removed, the panels pass through a tension detector 321, which detects tension changes in real time during the conveying process and dynamically adjusts the control to ensure smooth conveying. The panels then enter the peeling module 322 for layering, separating the two laminated single-sided panels. The separated panels are guided into their respective conveying paths by lead-out rollers 331 and finally wound up independently by multiple sets of take-up rollers 332. This online peeling and layered winding design not only eliminates the need for subsequent secondary peeling processes but also allows for real-time inspection of adhesive surface quality defects during the peeling process, effectively improving quality control.
[0046] Working principle of the invention: A heat-conducting plate 212 is provided in the central area of the heating plate. The temperature in this area is relatively high. Heat is quickly transferred to the heat-conducting block 213 in contact with it through the heat-conducting plate 212. After absorbing heat, the heat-conducting block 213 expands in volume, which pushes the heat-conducting bridge 214 to rotate around the bent rod 215 as the fulcrum. The excess heat in the central area is transferred to the heat transfer plate 216 in the edge area of the heating plate through the heat-conducting bridge 214, thereby supplementing the heating of the edge area of the heating plate. This eliminates the temperature difference between the center and the edge of the heating plate and avoids the problem of local over-melting or insufficient melting of TPI material during the pressing process.
[0047] If the TPI material is over-melted or under-melted, its surface viscosity changes, causing a corresponding change in the frictional force on the surface of the detection roller 241. The spiral spring 242 releases or contracts, causing the shaft of the detection roller 241 to rotate. This causes the conductive block 244 to slide on the arc-shaped rod 245. As the conductive block 244 slides, the current supplied by the conductive coil to the double-headed electric telescopic rod 251 changes, adaptively changing the elongation of the double-headed electric telescopic rod 251. This adjusts the pressing gap between the copper foil pressure roller 252 and the protective film pressure roller 253, preventing overflow caused by excessively molten TPI material due to excessive pressure and quality problems such as poor pressing and delamination caused by insufficient pressure.
[0048] When the copper foil drives the flattening roller 221 to rotate, the spiral ridge 222 generates an axial force on the copper foil, continuously pushing the copper foil from the middle to both sides. Due to the arched structure formed by the decreasing diameter of the flattening roller 221 from the middle to both sides, the tension in the middle of the copper foil is greater than that in the edge area, forming a natural lateral tension gradient, which further promotes the copper foil to automatically flatten during the conveying process, effectively eliminating wrinkle defects. In order to avoid the copper foil from warping, the controller controls the electric telescopic rod 233 to extend downward. The controller locks the extension length of the electric telescopic rod 233 by detecting the light intensity through the photoresistor 235, so that the pressure roller 234 presses the edge at a fixed length to prevent edge warping.
