Description

Technical Field

[0001] This invention relates to the field of steel plate leveling technology, specifically to a precision leveling device for high-hardness, high-expansion thin-walled mirror-like steel plates. Background Technology

[0002] Mirror-finish steel sheets are mainly used as isolation plates for circuit boards. The surface of the steel sheet must be very smooth and free of scratches, otherwise the scratches will be transferred onto the circuit board. Secondly, the steel sheet must be very flat. The specific processing steps for mirror-finish steel sheets are as follows: cutting, heat treatment, precision hole machining, and precision grinding. The steel sheet is mainly used as a carrier plate in the production of circuit boards in the circuit board industry.

[0003] The steel plate needs to have a high thermal expansion rate, which means it is greater than or equal to the expansion rate of copper. Only with this expansion rate can it expand simultaneously with the copper foil during the high-pressure bonding process of the circuit board without hindering the expansion of the copper foil. However, steel plates with a high expansion rate are not easy to flatten, especially with a thickness of less than 1.6mm and an area of ​​1.3m*1.6m. Currently, the industry mainly uses rolling to flatten the steel plate, which can usually achieve a warpage of 3mm. The flatness is still relatively low. Under the high temperature and pressure of pressing, the uneven steel plate will cause uneven flow and stretching of the core board, copper foil and PP sheet underneath, accelerating the deformation and wear of the circuit board. In severe cases, it can cause the circuit to deform and damage its normal use. Summary of the Invention

[0004] This invention proposes a high-hardness, high-expansion thin-walled mirror-finish steel plate precision leveling equipment to solve the problem that current leveling methods in the prior art are difficult to guarantee a high degree of flatness for mirror-finish steel plates.

[0005] The technical solution of the present invention is as follows: A high-hardness, high-expansion thin-walled mirror-like steel plate precision leveling device, comprising a frame and leveling rollers, wherein the leveling rollers are arranged in upper and lower groups, and multiple leveling rollers in the same group are connected by transmission. The upper and lower groups of leveling rollers rotate in opposite directions. The leveling roller located at the upper position can be raised and lowered on the frame. The device also includes:

[0006] A hot pressing mechanism, used for heating and flattening steel plates, includes:

[0007] A fixed heating plate is fixedly installed on the frame.

[0008] A movable heating plate, which can be raised and lowered above the fixed heating plate;

[0009] A heater, which is installed inside the fixed heating plate and the movable heating plate;

[0010] A cold pressing mechanism, used for cooling and flattening steel plates, includes:

[0011] A fixed cooling plate is fixedly installed on the frame.

[0012] A movable cooling plate, which can be raised and lowered above the fixed cooling plate;

[0013] A chiller, wherein the outlet of the chiller is connected to the fixed cooling plate, the inlet of the chiller is connected to the movable cooling plate, and the movable cooling plate is connected to the fixed cooling plate;

[0014] A flipping mechanism, disposed between the hot pressing mechanism and the cold pressing mechanism, is used to flip the hot-pressed steel plate. The flipping mechanism includes:

[0015] A rotating ring, which is rotatably mounted on the frame;

[0016] A rotating plate, which is provided with upper and lower sets, and the rotating plate is fixedly connected to the rotating ring;

[0017] A rotating roller is rotatably mounted on the rotating plate, with the top of the rotating roller located below flush with the tops of the fixed heating plate and the fixed cooling plate.

[0018] A transfer mechanism, comprising two sets, is respectively positioned between the hot pressing mechanism and the flipping mechanism, and between the flipping mechanism and the cold pressing mechanism. The transfer mechanism is used to transfer steel plates and includes:

[0019] A movable plate, which is movable and can be raised and lowered on the frame;

[0020] Anti-slip mat, the anti-slip mat is fixedly connected to the movable plate, and the anti-slip mat is in contact with the steel plate;

[0021] The fan is connected to the hot pressing mechanism, and the leveling roller is connected to the hot pressing mechanism. Specifically, the fan is connected to the fixed heating plate, and the leveling roller is connected to the fixed heating plate.

[0022] To further improve the leveling effect of the leveling roller on the steel plate, the leveling roller and the movable heating plate are connected, the movable heating plate is connected to a heating pipe, and the heating pipe is connected to multiple nozzles for blowing hot air onto the leveling roller.

[0023] To assist in cooling the steel plate after hot pressing, the fan is connected to a cold air duct, which is connected to multiple nozzles for blowing cold air onto the rotating roller.

[0024] To prevent the steel plate from falling during the flipping process, a limiting component is also included. This limiting component is used to limit the steel plate between the rotating rollers. The limiting component includes:

[0025] The limiting frame is provided in two parts, which are movably mounted on the rotating plate and are located on both sides of the rotating roller.

[0026] To enable the leveling roller located above to be raised and lowered, an adjusting plate is also included. An adjusting screw is rotatably connected to the frame, and an adjusting block is fixedly connected to the adjusting plate. The adjusting block and the adjusting screw are threadedly connected.

[0027] To enable the rotation of the rotating ring, multiple limiting rods are fixedly connected to the frame, and annular limiting grooves matching the limiting rods are opened on the rotating ring. A drive gear is rotatably mounted on the frame, and teeth that mesh with the drive gear are fixedly connected to the outside of the rotating ring.

[0028] To improve the leveling effect on the steel plate, a support plate is installed on the frame, and a pressure roller is movably installed on the adjustment plate. The bottom end of the pressure roller is flush with the bottom end of the rotating roller located above it.

[0029] The working principle and beneficial effects of this invention are as follows:

[0030] 1. In this invention, the height of the adjusting plate is adjusted by adjusting the screw to match the spacing between the upper and lower sets of leveling rollers with the thickness of the steel plate. The steel plate is conveyed by the rotation of the leveling rollers while being rolled and leveled. At the same time, hot air is delivered to the inside of the leveling rollers and heating pipes by the fan to preheat the steel plate and reduce its rigidity, so that the leveling rollers can level the steel plate.

[0031] 2. In this invention, a heater is used to heat a fixed heating plate and a movable heating plate, which in turn heat the steel plate. At the same time, the movable heating plate presses down and works with the fixed heating plate to flatten the steel plate. Heating the steel plate reduces its rigidity and increases its toughness, making it easier to flatten.

[0032] 3. In this invention, a chiller delivers chilled water to the interior of the fixed cooling plate and the movable cooling plate. The fixed cooling plate and the movable cooling plate cool the steel plate to fix it, compensate for the deformation caused by heat, restore the steel plate to normal temperature, and accelerate the solidification of the steel plate. Furthermore, the movable cooling plate descends and works in conjunction with the fixed cooling plate to flatten the steel plate again, further improving the flatness of the steel plate. At the same time, the steel plate cools and solidifies, maintaining its flat state.

[0033] 4. In this invention, the rotating ring drives the rotating roller to flip, which can flip the hot-pressed steel plate 180 degrees. Then, the steel plate moves between the fixed cooling plate and the moving cooling plate under the pushing action of the subsequent steel plate for cold pressing, flattening the steel plate on both sides and improving the flattening effect of the steel plate.

[0034] 5. In this invention, the fan blows air into the interior of the cold air duct to cool the steel plate that has been hot-pressed between the rollers, ensuring the cooling effect on the steel plate in the future. At the same time, the rotating ring drives the rollers to rotate, and the cold air duct blows air to various parts of the steel plate during the flipping process, improving the cooling effect on the steel plate.

[0053] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0054] like Figures 1 to 10As shown in the figure, this embodiment proposes a high-hardness, high-expansion thin-walled mirror-like steel plate precision leveling device, including a frame 1 and leveling rollers 2. The leveling rollers 2 are arranged in upper and lower groups, and multiple leveling rollers 2 in the same group are connected by transmission. The upper and lower groups of leveling rollers 2 rotate in opposite directions. The leveling roller 2 located above can be raised and lowered on the frame 1. To realize the raising and lowering of the leveling roller 2 located above, an adjusting plate 3 is also included. An adjusting screw 4 is rotatably connected to the frame 1, and an adjusting block 5 is fixedly connected to the adjusting plate 3. The adjusting block 5 and the adjusting screw 4 are threadedly connected. The leveling roller 2 is rotatably connected to the frame 1 or the adjusting plate 3 through a rotating shaft. Two adjacent rotating shafts at the same height are connected by a sprocket and chain transmission. Both the frame 1 and the adjusting plate 3 are equipped with There is a motor 6, and the output end of the motor 6 is fixedly connected to the drive gear 7. One of the multiple rotating shafts has a driven gear ring 8 fixedly mounted on its exterior. The driven gear ring 8 and the drive gear 7 mesh. The two motors 6 rotate in opposite directions. The motors 6 can drive multiple leveling rollers 2 located at the same height to rotate synchronously. The rotation tangent direction of the ends of the upper and lower sets of leveling rollers 2 that are close to each other is towards the hot pressing mechanism. The height of the adjusting plate 3 can be adjusted by rotating the adjusting screw 4, that is, the height of the leveling roller 2 located above can be adjusted so that the distance between the upper and lower sets of leveling rollers 2 is adapted to the thickness of the steel plate. The steel plate is conveyed and leveled by the leveling rollers 2. It also includes a hot pressing mechanism, a cold pressing mechanism, a flipping mechanism, a transfer mechanism, and a fan 13.

[0055] like Figures 1 to 5 As shown, to improve the leveling effect of the steel plate, a support plate 9 is installed on the frame 1, and a pressure roller 10 is movably installed on the adjusting plate 3. The bottom end of the pressure roller 10 is flush with the bottom end of the rotating roller 303 located above. An electric cylinder 11 is installed on the adjusting plate 3, and a drive frame 12 is fixedly connected to the output end of the electric cylinder 11. The pressure roller 10 is rotatably connected to the drive frame 12. A large gap is set in the middle of the multiple leveling rollers 2. The support plate 9 and the pressure roller 10 are located inside the gap. The electric cylinder 11 can drive the pressure roller 10 to move back and forth. The top end of the support plate 9 is flush with the top end of the leveling roller 2 located below. Through the movement of the pressure roller 10 and the cooperation of the support plate 9, the steel plate in the leveling process of the leveling roller 2 is further flattened, providing the steel plate with a variety of different leveling methods and improving the leveling effect of the steel plate.

[0056] like Figures 1 to 6As shown, the hot pressing mechanism is used to heat and flatten the steel plate. The hot pressing mechanism includes a fixed heating plate 101, a movable heating plate 102, and a heater 103. The fixed heating plate 101 is fixedly installed on the frame 1. The movable heating plate 102 is movably positioned above the fixed heating plate 101. A hydraulic cylinder 104 is installed on the frame 1. The movable heating plate 102 is fixedly connected to the output end of the hydraulic cylinder 104. A sliding rod is fixedly connected to the movable heating plate 102, and the sliding rod and the frame 1 are in sliding engagement. The heater 103 is installed on the fixed heating plate 101 and the movable heating plate 102. Inside 2, the heater 103 heats the fixed heating plate 101 and the movable heating plate 102. Under the rotation of the leveling roller 2, the steel plate is pushed to the fixed heating plate 101. The hydraulic cylinder 104 drives the movable heating plate 102 to descend. The surfaces of the movable heating plate 102 and the fixed heating plate 101 are flat. The two work together to flatten the steel plate. At the same time, the movable heating plate 102 and the fixed heating plate 101 heat the steel plate, causing stress relaxation in the steel plate. This reduces the rigidity and strength of the steel plate, making it more flexible and easier to flatten under the pressure of the movable heating plate 102 and the fixed heating plate 101.

[0057] like Figure 1 , Figure 2 , Figure 3 and Figure 9 As shown, the cold pressing mechanism is used to cool and flatten the steel plate. The cold pressing mechanism includes a fixed cooling plate 201, a movable cooling plate 202, and a chiller 203. The fixed cooling plate 201 is fixedly installed on the frame 1. The movable cooling plate 202 is vertically adjustable above the fixed cooling plate 201. A hydraulic cylinder 204 is installed on the frame 1. The movable cooling plate 202 is fixedly connected to the output end of the hydraulic cylinder 204. The outlet of the chiller 203 is connected to the fixed cooling plate 201, and the inlet of the chiller 203 is connected to the movable cooling plate 202. The movable cooling plate 202 is connected to the fixed cooling plate 201 via a flexible hose. The chiller 203 produces and delivers cold water. Cold water flows from bottom to top into the movable cooling plate 202 through a telescopic hose and then back to the chiller 203 for recycling. The cold water cools the movable cooling plate 202 and the fixed cooling plate 201. The steel plate enters between the fixed cooling plate 201 and the movable cooling plate 202. The hydraulic cylinder 204 drives the movable cooling plate 202 to descend. The surfaces of the movable cooling plate 202 and the fixed cooling plate 201 are flat. The two work together to flatten the steel plate. At the same time, the movable cooling plate 202 and the fixed cooling plate 201 cool the steel plate, allowing it to return to its normal temperature, improving the rigidity and hardness of the steel plate, reducing its deformation, and flattening it during cooling to maintain its flatness.

[0058] like Figures 1 to 8 As shown, the flipping mechanism is located between the hot pressing mechanism and the cold pressing mechanism, and is used to flip the hot-pressed steel plate. The flipping mechanism includes a rotating ring 301, a rotating plate 302, and a rotating roller 303. The rotating ring 301 is rotatably mounted on the frame 1. To realize the rotation of the rotating ring 301, multiple limiting rods 304 are fixedly connected to the frame 1. The rotating ring 301 has an annular limiting groove that matches the limiting rods 304. A driving rack 305 is movably mounted on the frame 1. Teeth 306 that mesh with the driving rack 305 are fixedly connected to the outside of the rotating ring 301. An electric cylinder 307 is mounted on the frame 1. 5. Fixedly connected to the output end of the electric cylinder 307, the rotating plate 302 is provided with upper and lower sets. The rotating plate 302 is fixedly connected to the rotating ring 301. The rotating roller 303 is rotatably mounted on the rotating plate 302. The top end of the lower rotating roller 303 is flush with the top end of the fixed heating plate 101 and the fixed cooling plate 201. To prevent the steel plate from falling off during the flipping process, a limiting component is also included. The limiting component is used to limit the steel plate between the rotating rollers 303. The limiting component includes a limiting frame 401. Two limiting frames 401 are provided. The limiting frames 401 are movably mounted on the rotating plate 302. Limiting frames 401 are located on both sides of the rotating roller 303. An electric cylinder 402 is mounted on the rotating plate 302. The limiting frames 401 are fixedly connected to the output end of the electric cylinder 402. The limiting frames 401 can move along the gap between the rotating rollers 303. The hot-pressed steel plate is pushed above the rotating roller 303. The electric cylinder 307 drives the drive rack 305 to reciprocate, causing the rotating ring 301 and rotating plate 302 to rotate, thus flipping the steel plate 180 degrees. The steel plate is then pushed to the cold-pressing mechanism, achieving double-sided flattening of the steel plate and further improving its flatness. A limiting rod 304 limits the rotation of the rotating ring 301, ensuring its smooth rotation. The distance between the two sets of rotating rollers 303 is greater than the thickness of the steel plate. The axis of the rotating ring 301 is located at the center between the two sets of rotating rollers 303. Before and after rotation, the top of the lower rotating roller 303 is always flush with the top of the fixed heating plate 101 and the fixed cooling plate 201, thus ensuring the smooth conveying of the steel plate. During the flipping process, the electric cylinder 402 drives the limiting plate to contact the edge of the steel plate, preventing the steel plate from falling through the gap between the rotating plates 302. After the flipping is completed, the electric cylinder 402 drives the limiting plate away from the steel plate to avoid obstructing the conveying of the steel plate. The electric cylinder 307 moves back and forth, causing the rotating ring 301 to rotate 180 degrees back and forth, preventing the wiring of the electric cylinder 402 from getting tangled.

[0059] like Figures 1 to 10As shown, the transfer mechanism is provided in two sets, which are respectively located between the hot pressing mechanism and the flipping mechanism, and between the flipping mechanism and the cold pressing mechanism. The transfer mechanism is used to transfer the steel plate. The transfer mechanism includes a moving plate 501 and an anti-slip pad 502. The moving plate 501 is movable and liftable on the frame 1. The anti-slip pad 502 is fixedly connected to the moving plate 501 and contacts the steel plate. An electric cylinder four 503 is installed on the frame 1. An electric cylinder five 504 is installed at the output end of the electric cylinder four 503. An electric cylinder six 505 is installed at the output end of the electric cylinder five 504. The moving plate 501... 01 is fixedly installed at the output end of electric cylinder six 505. Electric cylinder four 503 extends and retracts along the direction of steel plate movement, electric cylinder five extends and retracts vertically, and electric cylinder six 505 extends and retracts along the direction perpendicular to the steel plate movement. Electric cylinder six 505 can drive the moving plate 501 to move between the hot pressing mechanism or the rotating rollers 303. Electric cylinder five 504 drives the moving plate 501 to descend and press it on top of the steel plate. The extension and retraction of electric cylinder four 503 can drive the moving plate 501 to move in the direction of steel plate movement, pushing the steel plate to the subsequent process. Under the action of the moving plate 501, a single steel plate moves between the rotating rollers 303 or is removed from between the rotating rollers 303, avoiding the steel plate in hot or cold pressing from obstructing the rotation of the rotating ring 301.

[0060] like Figures 1 to 6 As shown, the fan 13 is connected to the hot pressing mechanism, and the leveling roller 2 is connected to the hot pressing mechanism. Specifically, the fan 13 is connected to the fixed heating plate 101, and the leveling roller 2 is connected to the fixed heating plate 101. The leveling roller 2 and the rotating shaft are both hollow structures and connected. Adjacent rotating shafts are rotatably connected through a connecting pipe. The upper rotating shaft near the moving heating plate 102 is rotatably connected to the moving heating plate 102 through a flexible hose, and the lower rotating shaft near the fixed heating plate 101 is rotatably connected to the fixed heating plate 101. The upper and lower rotating shafts away from the fixed heating plate 101 are rotatably connected through a telescopic flexible hose. The leveling roller 2 and The movable heating plate 102 is connected to a heating pipe 14, which is connected to multiple nozzles for blowing hot air onto the leveling roller 2. The fan 13 blows air onto the fixed heating plate 101, transporting the hot air inside the fixed heating plate 101 to the interior of the lower leveling roller 2. The hot air enters the interior of the upper leveling roller 2 through a telescopic hose and then enters the movable heating plate 102. The hot air inside the movable heating plate 102 is blown onto the leveling roller 2 through the heating pipe 14. The leveling roller 2 has a certain temperature, which preheats the steel plate during the leveling process, reducing the strength and rigidity of the steel plate, thereby facilitating the leveling of the steel plate.

[0061] To assist in cooling the steel plate after hot pressing, the fan 13 is connected to a cold air duct 15, which is connected to multiple nozzles for blowing cold air onto the rotating roller 303. While blowing air onto the fixed heating plate 101, the fan 13 also blows air into the interior of the cold air duct 15. The cold air duct 15 cools the steel plate between the rotating roller 303, reducing the thermal deformation of the rotating roller 303. At the same time, it provides initial cooling for the hot-pressed steel plate, facilitating its gradual return to normal temperature under the cooling effect of the cold pressing mechanism. This prevents the steel plate from remaining in a state of thermal deformation after leveling, thus maintaining the flatness of the steel plate. Furthermore, during the rotation of the rotating ring 301, the cold air duct 15 can provide more comprehensive air cooling for the steel plate, improving the cooling effect.

[0062] Compared to the 3mm warpage achieved by the commonly used rolling method in the industry, this embodiment reduces the warpage of the steel plate to 0.5mm through the rolling of the leveling roller 2 and the pressure roller 10, the heating and flattening of the steel plate by the hot pressing mechanism, and the cooling and flattening of the turned steel plate by the cold pressing mechanism. This greatly improves the flatness of the mirror steel plate and ensures the production quality of the circuit board.

[0063] The working principle or usage process of this high-hardness, high-expansion thin-walled mirror-like steel plate precision leveling equipment is as follows:

[0064] Adjust the height of the adjusting plate 3 according to the thickness of the steel plate. Rotate the adjusting screw 4 to adjust the height of the adjusting plate 3 so that the distance between the upper and lower sets of leveling rollers 2 is adapted to the thickness of the steel plate. Place the steel plate between the two sets of leveling rollers 2. The motor 6 drives the leveling rollers 2 to rotate. The leveling rollers 2 convey and level the steel plate. The electric cylinder 11 drives the pressure roller 10 to move back and forth. The pressure roller 10 and the support plate 9 cooperate to flatten the steel plate.

[0065] The steel plate is conveyed to the top of the fixed heating plate 101. The heater 103 heats the moving heating plate 102 and the fixed heating plate 101. The hydraulic cylinder 104 drives the moving heating plate 102 to descend. The moving heating plate 102 and the fixed heating plate 101 cooperate to flatten the steel plate.

[0066] Electric cylinder six 505 moves the moving plate 501 below the moving heating plate 102. Electric cylinder five 504 presses the anti-slip pad 502 against the steel plate surface. Electric cylinder four 503 moves the moving plate 501 towards the rotating roller 303, moving the steel plate a certain distance towards the roller 303. Then, electric cylinder five 504 raises the moving plate 501, and electric cylinder four 503 returns to its original position. Electric cylinder five 504 continues to lower the protective pad to press it against the steel plate. Electric cylinder four 503 continues to move the steel plate a certain distance towards the rotating roller 303. The above operation is repeated until the steel plate is completely between the rotating rollers 303. Electric cylinder two 402 moves the limiting frame 401 to contact the edge of the steel plate. The electric cylinder 505 limits the movement of the steel plate 501, which moves the moving plate 501 out from between the rollers 303 to avoid obstructing the rotation of the rotating ring 301. The electric cylinder 307 drives the drive rack 305 to move, thereby rotating the rotating ring 301 and causing the steel plate to rotate 180 degrees. The steel plate is then transported to the fixed cooling plate 201. The chiller 203 cools the fixed cooling plate 201 and the moving cooling plate 202. The hydraulic cylinder 204 drives the moving cooling plate 202 to descend. The moving cooling plate 202 and the fixed cooling plate 201 work together to flatten the steel plate. Subsequent steel plate movement pushes the flattened steel plate above the fixed cooling plate 201 down for collection.

[0067] During the leveling process, the blower 13 blows air into the fixed heating plate 101 and the interior of the cold air pipe 15. The gas in the fixed heating plate 101 enters the interior of the leveling roller 2 and then enters the interior of the moving heating plate 102. The hot air in the moving heating plate 102 is blown onto the leveling roller 2 through the heating pipe 14, which improves the leveling effect of the leveling roller 2 on the steel plate. The cold air pipe 15 cools the steel plate during the turning process.

[0068] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
