Description
Technical Field
[0001] This utility model relates to the technical field of antistatic board processing equipment, specifically to a leveling device for antistatic boards. Background Technology
[0002] Antistatic sheets are special functional boards used in electronics, medical, and precision manufacturing fields. Their surface resistance is typically in the range of 10^6 to 10^9 Ω, effectively preventing static electricity accumulation and avoiding electrostatic discharge (ESD) damage to sensitive devices. These boards are usually made of polymer composite materials or metal-based copper-clad laminates, which have high rigidity. However, during processing or storage, uneven stress can easily cause warping and deformation, affecting subsequent precision assembly or use. Antistatic sheets require high-precision leveling before leaving the factory.
[0003] Currently, there are two main methods for leveling sheet materials. One is roller leveling, which uses staggered rollers to repeatedly bend and deform the sheet material to eliminate stress and flatness errors. This method is suitable for continuous production of large-area sheets. However, this method can cause bending and deformation of the sheet material at the gaps between the rollers, resulting in unsatisfactory final flatness. The other method is pressure plate leveling, which uses two parallel large pressure plates to apply huge and uniform pressure to flatten the sheet material. This method is particularly suitable for thick plates or scenarios with high flatness requirements. However, this method usually requires manual or robotic arms to place the sheet material, which is inefficient. Furthermore, for materials such as thermosetting laminates and certain composite materials, the leveling effect of mechanical force alone is limited, and the material is prone to springback. Simply heating it may also cause new deformation.
[0004] Therefore, we propose a leveling device for antistatic boards to solve the problems mentioned above. Utility Model Content

[0012] Preferably, an independent pressure plate is fixedly connected to the outside of the adjustment frame. The independent pressure plate has the same shape as the switching groove and slides inside the switching groove.
[0013] Preferably, the heating assembly includes a high-temperature air inlet pipe and an exhaust pipe that communicate with the interior of the lower pressure plate, wherein the high-temperature air inlet pipe is used to input high-temperature gas into the interior of the lower pressure plate.

After pressure leveling, the antistatic sheet is pushed to the output table for output via a conveying and adjusting assembly, eliminating the need for manual intervention and improving processing efficiency. The exhaust pipe extracts the hot air from the adjusting groove for reheating, ensuring hot air circulation and a constant temperature. Attached Figure Description

[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0020] Example 1: Please see Figure 1-4 This utility model provides a technical solution: A leveling device for antistatic boards includes an input platform 1 with a preheating channel 2. A leveling mechanism is provided at the front end of the input platform 1. The antistatic board is conveyed on the input platform 1 and undergoes preliminary heating when passing through the preheating channel 2, which facilitates its reheating in the leveling mechanism and quickly raises it to the hot-pressing temperature, saving leveling time. The leveling mechanism includes an upper pressure plate 4 and a lower pressure plate 5 arranged in parallel. A gantry frame 6 is provided on the outside of the upper pressure plate 4, and a cylinder 7 is installed on the gantry frame 6 to push the upper pressure plate 4 to lift and adjust its position. The antistatic board enters the lower pressure plate 5 after passing through the input platform 1. A position monitoring component is provided on the sides of the upper pressure plate 4 and the lower pressure plate 5 to detect the position of the antistatic board. A conveying adjustment component is provided between the upper pressure plate 4 and the lower pressure plate 5 to adjust the position of the antistatic board between the upper pressure plate 4 and the lower pressure plate 5. After the antistatic board is fully adjusted between the upper pressure plate 4 and the lower pressure plate 5, it is hot-pressed and leveled.
[0021] In the above solution, the antistatic board is automatically transported between the upper pressure plate 4 and the lower pressure plate 5 through the cooperation of the input station 1 and the conveying adjustment component. No manual handling or robotic arm intervention is required, making the operation convenient and more efficient.
[0022] The position monitoring component includes an L-shaped frame 9, one end of which is fixedly connected to the outside of the upper pressure plate 4. A grating sensor 10 is installed on the inside of the L-shaped frame 9. The grating sensor 10 is used to monitor the position of the anti-static plate on the lower pressure plate 5. Two sets of position monitoring components are provided, located at opposite ends of the lower pressure plate 5. When the anti-static plate has completely passed the first set of grating sensors 10 and has not passed the second set of grating sensors 10, the anti-static plate is completely positioned on the lower pressure plate 5, allowing for hot-pressing and leveling.
[0023] Both ends of the upper pressure plate 4 and the lower pressure plate 5 are provided with switching grooves 12, which are rectangular. Adjustment grooves 13 are provided inside both the upper pressure plate 4 and the lower pressure plate 5, and the conveying adjustment assembly is installed inside the adjustment groove 13. The conveying adjustment assembly includes a friction roller 14 and a U-shaped roller frame 15. The friction roller 14 is rotatably connected inside the U-shaped roller frame 15. An electric telescopic rod 16 is fixedly installed inside the adjustment groove 13. The telescopic end of the electric telescopic rod 16 is fixedly connected to the U-shaped roller frame 15, and the U-shaped roller frame 15 is slidably connected inside the adjustment groove 13.
[0024] In the above scheme, switching slots 12 are provided at both ends of the upper pressure plate 4 and the lower pressure plate 5 to facilitate the friction roller 14 to enter the surface of the upper pressure plate 4 and the lower pressure plate 5. A servo motor for driving the friction roller 14 to rotate is installed on the U-shaped roller frame 15. The U-shaped roller frame 15 and the friction roller 14 are pushed to extend and retract by the electric telescopic rod 16. By controlling the friction roller 14 on the upper pressure plate 4 and the lower pressure plate 5 to simultaneously adhere to the surface of the antistatic board, the rotation of the friction roller 14 drives the antistatic board to move and adjust its position. The position of the antistatic board is monitored by two sets of grating sensors 10. When the antistatic board enters the appropriate position, the friction roller 14 retracts into the adjustment slot 13, and the cylinder 7 pushes the upper pressure plate 4 and the lower pressure plate 5 closer together to flatten the antistatic board.
[0025] A pressure sensor 17 is installed between the electric telescopic rod 16 and the U-shaped roller frame 15. The pressure sensor 17 can detect the pressure between the friction roller 14 and the antistatic plate, thereby adjusting the friction force of the friction roller 14 to move the antistatic plate, and at the same time avoiding excessive pressure from the friction roller 14 on the antistatic plate, which could cause damage.
[0026] The length of the friction roller 14 is less than the length of the switching groove 12, and the diameter of the friction roller 14 is less than the width of the switching groove 12, which is beneficial for the friction roller 14 to contact the antistatic plate through the switching groove 12.
[0027] An adjusting frame 18 is rotatably connected to the outside of the U-shaped roller frame 15. The adjusting frame 18 is U-shaped, and its two ends are rotatably connected to the outside of the U-shaped roller frame 15. A stepper motor 19 is installed on one side of the U-shaped roller frame 15, and the rotating shaft of the stepper motor 19 is fixedly connected to one end of the adjusting frame 18. An independent pressure plate 20 is fixedly connected to the outside of the adjusting frame 18. The independent pressure plate 20 has the same shape as the switching groove 12, and the independent pressure plate 20 slides in cooperation with the switching groove 12.
[0028] In the above scheme, the stepper motor 19 drives the adjustment frame 18 to rotate, and the independent pressure plate 20 rotates with the adjustment frame 18 to adjust the angle. When hot pressing is performed, the independent pressure plate 20 is rotated to be flush with the switching groove 12. The electric telescopic rod 16 pushes the independent pressure plate 20 into the switching groove 12, so that the switching groove 12 on the upper pressure plate 4 and the lower pressure plate 5 is closed, further ensuring the flattening effect of the upper pressure plate 4 and the lower pressure plate 5 on the antistatic board, so that the antistatic board has a high flatness.
[0029] The working principle of the antistatic board leveling equipment in Example 1 is as follows: The antistatic board is first conveyed to the preheating channel 2 through the input table 1 for preliminary heating, and then enters the surface of the lower pressure plate 5 of the leveling mechanism; at this time, the grating sensors 10 on the two sets of L-shaped frames 9 monitor the position of the board in real time, and the electric telescopic rod 16 in the adjustment groove 13 pushes the U-shaped roller frame 15 to extend, so that the friction roller 14 contacts the board through the switching groove 12. The servo motor drives the friction roller 14 to rotate and drive the board to be finely adjusted to the precise position; the antistatic board is adjusted to be completely on the lower pressure plate 5, and the pressure sensor 17 monitors the pressure of the friction roller 14 in real time to ensure that the board is not damaged during the adjustment process; after the positioning is completed, the friction roller 14 retracts into the adjustment groove 13, and at the same time the stepper motor 19 drives the adjustment frame 18 to rotate, so that the independent pressure plate 20 is aligned with the switching groove 12 and pushed by the electric telescopic rod 16 to close the groove; finally, the cylinder 7 on the gantry 6 drives the upper pressure plate 4 to press down, and together with the lower pressure plate 5, the board is hot-pressed and leveled. This solution, through the synergistic effect of preheating channel 2, automatic conveying and positioning system and closed pressure plate structure, not only solves the efficiency problem of manual intervention required by traditional pressure plate method, but also avoids the insufficient flatness caused by roller method. At the same time, the independent pressure plate 20 design ensures the uniformity of pressure distribution during hot pressing, and achieves efficient and high-precision leveling of antistatic board.
[0030] Example 2: Please see Figure 1-4 Furthermore, in conjunction with Embodiment 1, heating components are provided on the surfaces of both the upper pressure plate 4 and the lower pressure plate 5. An output platform 24 is provided at the end of the lower pressure plate 5 away from the input platform 1. A support base 25 is fixedly connected to the bottom of the lower pressure plate 5, and a support column for lifting and adjusting is provided at the bottom of the support base 25.
[0031] The heating assembly includes a high-temperature air inlet pipe 22 and an exhaust pipe 23 that communicate with the interior of the lower pressure plate 5. The high-temperature air inlet pipe 22 is used to input high-temperature gas into the interior of the lower pressure plate 5. One side of the adjustment groove 13 of the upper pressure plate 4 is close to the surface of the upper pressure plate 4 where it is pressurized. The adjustment groove 13 of the lower pressure plate 5 is arranged in the same manner. The high-temperature air inlet pipe 22 and the exhaust pipe 23 of the heating assembly are simultaneously connected to the interior of both adjustment grooves 13. The high-temperature air inlet pipe 22 delivers high-temperature gas to the adjustment grooves 13 of both the upper pressure plate 4 and the lower pressure plate 5, so that the two pressure plates heat up quickly and evenly, and heat the clamped antistatic board on both sides. The exhaust pipe 23 extracts the hot gas in the adjustment groove 13 for recycling, maintaining a constant hot-pressing temperature, and ensuring that the board completes the stress relief and leveling process at the optimal temperature.
[0032] In the above scheme, during hot pressing, high-temperature gas is simultaneously supplied to the adjustment grooves 13 of the upper pressure plate 4 and the lower pressure plate 5 through the high-temperature air inlet pipe 22, so that the gas can be heated rapidly to heat the antistatic board. Then, pressure is applied and leveled to eliminate the internal stress of the board. After the pressure is applied and leveled, the antistatic board is pushed to the output table 24 for output through the conveying adjustment component. No manual intervention is required, which improves the processing efficiency. The exhaust pipe 23 extracts the hot gas inside the adjustment groove 13 and reheats it to ensure the circulation of hot gas and the constant temperature.
[0033] Furthermore, it also includes a central controller; the grating sensor 10, the electric telescopic rod 16, the pressure sensor 17, and the stepper motor 19 are all electrically connected to the central controller; the grating sensor 10 is used to send the detected antistatic board position offset signal to the central controller.
[0034] After leveling is completed, the central controller starts the conveying adjustment component, the electric telescopic rod 16 pushes the U-shaped roller frame 15 to extend, the friction roller 14 contacts the plate and pushes it to the output table 24 through the servo motor drive; the pressure sensor 17 monitors the pushing pressure in real time to ensure that the conveying process is stable and reliable, and realizes a fully automatic process from leveling to output.
[0035] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
