Description

Technical Field

[0001] This invention relates to the field of ultra-thin electronic glass manufacturing technology, specifically to an ultra-thin electronic glass forming equipment and its operating method. Background Technology

[0002] Ultra-thin electronic glass is widely used in electronic products such as mobile phones and tablets, and is usually produced using the overflow pull-down method.

[0003] In actual use, the flow rate and final thickness of the glass melt after it flows out of the solution tank in mainstream forming equipment mainly rely on the initial settings and the operator's experience, and cannot be quickly and accurately adjusted during the production process.

[0004] Changing the thickness of the glass strip often requires stopping the machine for adjustments, which is not only inefficient but also wastes materials. This results in poor thickness consistency in the product, making it difficult to meet the stringent requirements for glass uniformity in high-end electronic products.

[0005] To form a glass ribbon, many devices merge two streams of molten glass at a sharp edge. This merging method has a significant problem: if the two streams have even slight differences in flow rate or temperature, they cannot fully fuse, resulting in a clear line, or "stitch," within the glass ribbon. This line is an internal defect that weakens the glass's strength and affects its optical properties, leading to a lower yield.

[0006] Therefore, we propose a molding equipment and operation method for ultra-thin electronic glass to solve the problems mentioned above. Summary of the Invention

[0007] This invention provides forming equipment and operating method for ultra-thin electronic glass, which can solve the problem in the prior art that after the glass melt flows out of the solution tank, its flow rate and the final forming thickness mainly rely on the initial settings and the operator's experience, and cannot be quickly and accurately adjusted during the production process.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A molding equipment for ultra-thin electronic glass includes a glass solution tank, a manifold is provided below the glass solution tank, the upper end of the manifold is connected to the bottom of the glass solution tank, a geometrically symmetrical guide cavity is provided inside the manifold, and a flow divider is longitudinally slidably connected inside the guide cavity. The flow divider cooperates with the guide cavity to symmetrically divide the glass liquid entering the guide cavity. The bottom center of the manifold is provided with an integrally formed fusion cavity with an opening facing downwards, and the upper end of the glass solution tank is equipped with a first fine-tuning component for longitudinal adjustment of the splitter; the manifold includes two symmetrical guide plates, and the end of the guide plate near the glass solution tank is flexibly connected to it.

[0010] Preferably, multiple sets of heating elements and temperature sensors are pre-embedded inside the tapered section, throat, and expansion section of the flow guide plate near the fusion cavity, and an integrated controller is installed on the combiner, with the heating elements and temperature sensors electrically connected to the integrated controller.

[0011] Preferably, the heating element includes a heating channel formed by a high-temperature resistant metal-ceramic tube, and a resistance wire for heating runs through the inside of the heating channel.

[0012] Preferably, the guide plate is a tough steel plate, the upper end of the guide plate is integrally formed with the bottom of the glass solution tank, the thickness of the guide plate at the connection with the glass solution tank is less than the thickness of the guide plate, and the glass solution tank is provided with sealing plates on both sides perpendicular to the direction of the guide plate, and the sealing plates on both sides abut against the two ends of the guide plate respectively.

[0013] Preferably, the end of the expanding section is provided with a smooth micro-dam structure, which is used to ensure that the mixed molten glass overflows evenly.

[0014] Preferably, a laser glass thickness gauge and a glass traction mechanism for glass conveying are installed below the guide plate in the gradually expanding section. The glass traction mechanism includes multiple sets of traction rollers. The two traction rollers in each set are arranged in pairs and rotatably connected to the inner sides of two closed plates. A rotary drive assembly corresponding to the multiple sets of traction rollers is installed on the outer side of the closed plates. The rotary drive assembly drives the two traction rollers in the same set to rotate inward simultaneously for traction of the glass.

[0015] Preferably, the first fine-tuning component includes a guide post, a cover plate fixedly connected inside the glass solution tank, the guide post sliding through the cover plate, a support plate fixedly connected to the top of the glass solution tank, the guide post being square and having a micron-level threaded rod installed inside, a bearing installed on the outer side of the upper end of the micron-level threaded rod, the bearing being rotatably connected to the inside of the support plate, a turntable fixedly connected to the end of the micron-level threaded rod away from the guide post, the turntable driving the micron-level threaded rod to rotate, and the rotation of the micron-level threaded rod driving the guide post to slide longitudinally along the inside of the cover plate.

[0016] Preferably, the second fine-tuning component includes a micron-level electric actuator. One end of the micron-level electric actuator rotates with the bottom of the glass solution tank, and the other end is rotatably connected to the outer side of the guide plate near the throat. The micron-level electric actuator is tilted and pushes the guide plate to rotate around the connection between the guide plate and the glass solution tank, so that the two guide plates move closer or further apart, thereby adjusting the thickness of the glass forming.

[0017] An operating method for the ultra-thin electronic glass forming equipment of claim 1 includes the following steps: S1. The molten glass flows into the manifold from the bottom of the glass solution tank, and is then split symmetrically by the flow divider and the guide cavity. S2. Two streams of molten glass flow downward into the fusion chamber from the splitting gap. After acceleration in the converging section, extrusion and shearing at the throat, fusion in the expanding section, and leveling by the micro-dam, a uniform glass band is formed. S3. Adjust the longitudinal position of the distributor by adjusting the first fine-tuning component and control the opening of the distributor gap to adjust the flow rate of the molten glass. S4.

Start the glass traction mechanism. Multiple sets of traction rollers rotate synchronously to pull the glass strip downward at a uniform speed, ultimately forming ultra-thin electronic glass of the predetermined thickness.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are: The present invention first provides a stable glass liquid through a glass solution tank, and the distributor in the manifold is responsible for distributing the glass liquid. The first fine-tuning component can precisely adjust the opening size of the distributor gap, thereby directly affecting the flow rate and final thickness of the glass liquid.

[0019] The guide plate is a key component of the manifold. The second fine-tuning component can drive the guide plate to produce a small elastic deformation, thereby precisely controlling the gap between the two glass liquid streams and ensuring the uniformity of the glass liquid flow.

[0020] The fusion chamber employs a Venturi-like tubular structure, comprising a converging section, a throat, and a dilating section. The molten glass accelerates in the converging section, undergoes intense shearing in the throat, and decelerates and mixes thoroughly in the dilating section. This process effectively eliminates internal sutures.

[0021] The fusion chamber is equipped with a smooth micro-weir at the end, where the mixed glass liquid overflows evenly, further ensuring the smoothness of the liquid surface.

[0022] The guide plate has embedded heating elements and temperature sensors that can monitor and regulate the temperature of the molten glass. This ensures the molten glass maintains optimal viscosity and avoids problems caused by temperature fluctuations.

[0023] The upper part of the guide plate adopts a flexible connection, and the micron-level electric push rod can drive it to make online fine adjustments, thereby achieving precise control of the forming thickness.

[0024] Below the gradually expanding section, a laser glass thickness gauge is installed. It monitors the thickness of the initially formed glass strip in real time and feeds the data back to the control system, forming a closed-loop adjustment system.

[0025] The glass traction mechanism is equipped with multiple sets of traction rollers, which provide stable and uniform traction force to ensure that the glass strip is pulled down smoothly.

[0026] Ultimately, through the coordinated operation of flow control, temperature regulation, and online monitoring, the device produces ultra-thin electronic glass with uniform thickness and no defects, effectively solving the problems of inconsistent thickness and seam lines in traditional technologies, and significantly improving product yield and production efficiency.

[0029] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0030] Example 1: Please see Figure 1-5 The present invention provides a technical solution: A molding equipment for ultra-thin electronic glass includes a glass solution tank 1, a manifold is provided below the glass solution tank 1, the upper end of the manifold is connected to the bottom of the glass solution tank 1, a geometrically symmetrical guide cavity 3 is provided inside the manifold, and a flow divider 4 is longitudinally slidably connected inside the guide cavity 3. The flow divider 4 cooperates with the guide cavity 3 to symmetrically divide the glass liquid entering the guide cavity 3. The bottom center of the forming equipment manifold is provided with an integrally formed fusion chamber 5 with an opening facing downwards, which is used to squeeze, shear and fully mix the glass liquid flowing down from the two side split gaps in the forming equipment fusion chamber 5 before merging to form a glass ribbon that is pulled down. In order to adjust the flow rate and the thickness of the formed glass, a first fine-tuning component for longitudinal adjustment of the distributor 4 is installed at the upper end of the glass solution tank 1; the distributor includes two symmetrical guide plates 7, one end of which is connected to the glass solution tank 1 in a flexible manner. A second fine-tuning component for adjusting the gap between the two guide plates 7 is provided below the glass solution tank 1.

[0031] In the above scheme, firstly, the glass liquid flows from the bottom of the glass solution tank 1 into the lower concentrator. The concentrator is equipped with a geometrically symmetrical guide cavity 3, which contains a longitudinally sliding diverter 4. The diverter 4 and the guide cavity 3 work together to divide the inflowing glass liquid into two symmetrical liquid streams. Two streams of molten glass flow downwards from the split gaps on both sides of the manifold, eventually entering the fusion chamber 5 located at the center of the bottom of the manifold. This fusion chamber 5 can be configured as a shallow U-shape or V-shape, allowing the two streams of molten glass to squeeze, shear, and mix thoroughly within the chamber, effectively eliminating seams that may form due to differences in flow rate or temperature, thereby improving the uniformity of the glass ribbon.

[0032] The mixed molten glass converges from the lower end of the fusion chamber 5 and is pulled downwards to form a continuous, uniform, ultra-thin electronic glass ribbon. To adjust the flow rate of the molten glass and the final thickness of the glass ribbon, the longitudinal position of the distributor 4 can be controlled by the first fine-tuning component, thereby changing the opening size of the distributor slit. At the same time, the gap between the two guide plates 7 in the distributor is adjusted by the second fine-tuning component to further refine the forming process. This device effectively controls the flow rate and forming thickness of the molten glass by controlling the position of the distributor 4 and the gap of the guide plate 7. It also eliminates the seam lines that may be formed due to differences in flow rate or temperature through the fusion chamber 5, thereby improving the uniformity of the glass ribbon.

[0033] The guide plate 7 of the forming equipment is a tough steel plate. The upper end of the guide plate 7 is integrally formed with the bottom of the glass solution tank 1. The thickness of the connection between the guide plate 7 and the glass solution tank 1 is less than the thickness of the guide plate 7. The glass solution tank 1 is provided with sealing plates 19 on both sides perpendicular to the direction of the guide plate 7. The sealing plates 19 on both sides abut against the two ends of the guide plate 7 respectively.

[0034] In the above scheme, the guide plate 7 is made of a tough steel plate, with its upper end integrally formed with the bottom of the glass solution tank 1. A flexible hinge structure is formed at the connection point by reducing the thickness. This design allows the guide plate 7 to undergo slight elastic deformation at its connection point with the solution tank when subjected to the force of the second fine-tuning component, thereby precisely changing the gap between the bottoms of the two guide plates 7. The sealing plates 19 on both sides of the device abut against the ends of the guide plates 7 to form a sealed flow channel, while providing necessary structural support and sealing for the manifold, ensuring stable flow of the molten glass within the confined flow channel.

[0035] The end of the gradually expanding section 11 of the forming equipment is provided with a smooth micro-dam structure 12, which is used to make the mixed glass liquid overflow evenly.

[0036] In the above scheme, a smooth micro-dam structure 12 is designed at the end of the gradually expanding section 11 below the fusion chamber 5. When the glass liquid after being fully mixed in the fusion chamber 5 flows to this point, it will be blocked by the micro-dam and instead overflow evenly over the dam body. This process can effectively smooth out any thickness or flow rate unevenness that may remain in the glass liquid during the flow process, making the liquid surface more flat and uniform before entering the drawing and forming stage, which is conducive to forming an ultra-thin glass strip with a consistent thickness.

[0037] The forming equipment guide plate 7 is located below the gradually expanding section 11 and is equipped with a laser glass thickness gauge 20 and a glass traction mechanism for glass conveying. The glass traction mechanism of the forming equipment includes multiple sets of traction rollers 22. The two traction rollers 22 in each set are arranged in pairs and rotatably connected to the inside of two closed plates 19. A rotary drive assembly corresponding to the multiple sets of traction rollers 22 is installed on the outside of the closed plates 19. The rotary drive assembly drives the two traction rollers 22 in the same set to rotate inward simultaneously for traction of the glass.

[0038] In the above scheme, a laser glass thickness gauge 20 is installed below the expanding section 11 to monitor the thickness of the initially formed glass strip in real time. Simultaneously, the glass traction mechanism uses multiple pairs of traction rollers 22 to clamp the glass strip inside the sealing plate 19. The rotation drive assembly drives the two traction rollers 22 in the same group to rotate synchronously inward, applying a stable and uniform pulling force to continuously pull the glass strip downward. This process, combined with data feedback from the laser glass thickness gauge 20, allows for precise control of the final thickness and forming quality of the glass strip by adjusting the traction speed of the glass traction mechanism and the flow rate of the molten glass. The spacing between the two traction rollers 22 in the same group can be adjusted according to the actual glass thickness produced.

[0039] Example 2: Please see Figure 2-4Furthermore, in conjunction with Example 1, it is obtained that, The first fine-tuning component of the molding equipment includes a guide post 24, a cover plate 25 fixedly connected inside the glass solution tank 1, the guide post 24 sliding through the cover plate 25, a support plate 26 fixedly connected to the top of the glass solution tank 1, the guide post 24 is square and has a micron-level threaded rod 27 installed inside, a bearing is installed on the upper external part of the micron-level threaded rod 27, the bearing is rotatably connected to the inside of the support plate 26, a turntable 29 is fixedly connected to the end of the micron-level threaded rod 27 away from the guide post 24, the turntable 29 drives the micron-level threaded rod 27 to rotate, and the rotation of the micron-level threaded rod 27 drives the guide post 24 to slide longitudinally along the inside of the cover plate 25.

[0040] In the above scheme, the first fine-tuning component is used to precisely control the longitudinal position of the distributor 4. When the operator rotates the turntable 29, it drives the micron-level threaded rod 27 to rotate synchronously. Since the micron-level threaded rod 27 is mounted in the support plate 26 through bearings, its rotational motion is converted into precise linear displacement. The square guide post 24, which meshes with the micron-level threaded rod 27 and is restricted from rotation, then produces precise longitudinal lifting and lowering under the guidance of the cover plate 25. The lower end of the guide post 24 is connected to the distributor 4, thereby directly transmitting the micron-level displacement to the distributor 4. The distributor 4 is rhomboid, and its lower end cooperates with the V-shaped structure inside the guide cavity 3. By changing the height of the distributor 4 in the guide cavity 3, the opening size of the distribution slit is adjusted, thereby achieving precise control of the glass melt flow rate.

[0041] The second fine-tuning component of the forming equipment includes a micron-level electric push rod 30. One end of the micron-level electric push rod 30 rotates with the bottom of the glass solution tank 1, and the other end is rotatably connected to the outer side of the guide plate 7 near the throat 10. The micron-level electric push rod 30 is tilted and pushes the guide plate 7 to rotate around the connection between the guide plate 7 and the glass solution tank 1, so that the two guide plates 7 move closer or further apart, which is used to adjust the thickness of the glass forming.

[0042] In the above scheme, the second fine-tuning component is used to control the glass forming thickness by adjusting the gap of the guide plate 7; when the micron-level electric push rod 30 is started and performs the extension or retraction action, a push or pull force is applied to the guide plate 7. Since the upper end of the guide plate 7 is flexibly connected to the bottom of the solution tank, forming a movable fulcrum, the applied push or pull force will drive the entire guide plate 7 to rotate slightly inward or outward around this upper fulcrum. Driven by this, the two guide vanes 7 move closer or further apart synchronously, thereby precisely changing the gap width between their bottoms. This gap directly determines the thickness of the final formed glass strip, enabling precise online adjustment of the glass thickness. This width is the distance between the micro-dams on both sides of the end of the expanding section 11, and the distance between the micro-dams is less than the width of the throat 10 of the guide cavity 3.

[0043] Example 3: Please see Figure 3 Furthermore, in conjunction with Embodiment 1, it is further found that the fusion cavity 5 of the molding equipment is a Venturi-like tubular structure, and its flow channel is smoothly connected by a tapering section 9, a throat 10 and a widening section 11; the throat 10 of the molding equipment is the narrowest part of the fusion cavity 5; a smooth micro-dam structure 12 is provided at the end of the widening section 11 of the molding equipment to make the mixed glass liquid overflow evenly.

[0044] In the above scheme, the fusion chamber 5 is designed as a Venturi-like tubular structure. Its flow channel is smoothly connected by a converging section 9, a throat 10, and a expanding section 11. The molten glass first enters the converging section 9, where the flow velocity gradually increases. Then it passes through the narrowest throat 10, where the flow velocity reaches its maximum. The two streams of molten glass are subjected to strong compression and shearing at this point, achieving initial mixing. Finally, it enters the expanding section 11, where the flow velocity decreases and the pressure rises, making the mixing process more thorough and stable. The smooth micro-weir structure 12 set at the end of the expanding section 11 provides final obstruction and leveling for the outflowing molten glass, allowing it to flow downwards in a uniform overflow manner, forming a glass ribbon of uniform thickness.

[0045] Multiple sets of heating elements and temperature sensors are pre-embedded inside the tapered section 9, throat 10 and expanding section 11 of the molding equipment guide plate 7 near the fusion cavity 5. An integrated controller is installed on the combiner, and the heating elements and temperature sensors are electrically connected to the integrated controller.

[0046] Inside the tapered section 9, throat 10, and expanding section 11 of the guide plate 7 near the fusion chamber 5, multiple sets of heating elements and temperature sensors are pre-embedded. The sensors monitor the temperature of the molten glass in each key area in real time and transmit the data to the integrated controller. The controller precisely controls the power output of each heating element according to the set process requirements and real-time temperature data, thereby adjusting the temperature of the molten glass in the flow channel locally or as a whole, ensuring that its viscosity is within the optimal forming range, and guaranteeing the mixing effect and the stability of the forming.

[0047] In the above scheme, when the current passes through the resistance wire 18, Joule heat is generated. The metal ceramic tube has good heat resistance and insulation, which can efficiently and evenly conduct heat to the flow channel wall it wraps, thereby heating the glass liquid flowing through the area and preventing it from increasing in viscosity or solidifying due to temperature drop, ensuring that the glass liquid maintains good fluidity and plasticity throughout the entire forming process.

[0048] The working principle of the ultra-thin electronic glass forming equipment is as follows: The molten glass first flows from the bottom of the glass solution tank 1 into the manifold below it. The geometrically symmetrical guide cavity 3 and the rhomboid distributor 4 inside the manifold evenly divide the molten glass into two streams. The two streams flow downward through the split gaps on both sides and enter the fusion cavity 5 integrally formed at the bottom of the manifold. The fusion cavity 5 adopts a Venturi-like tubular structure, including a tapered section 9, a throat 10 and a diffusing section 11. This allows the molten glass to undergo acceleration, strong extrusion shearing and deceleration backflow during the flow, achieving full mixing and effectively eliminating the seam lines caused by uneven flow rate or temperature. The mixed molten glass overflows evenly on the smooth micro-weir at the end of the diffusing section 11, further leveling the liquid surface. To precisely control the flow rate and final thickness, the first fine-tuning component drives a micron-level threaded rod 27 by rotating a turntable 29, which in turn raises and lowers the distributor 4 to adjust the opening of the distribution slit. The second fine-tuning component drives a micron-level electric push rod 30 to slightly move the guide plate 7 around its upper flexible connection point, changing the bottom gap between the two guide plates 7 and the spacing of the micro-dams, thereby controlling the forming thickness. The heating element and temperature sensor embedded in the flow channel are controlled by an integrated controller to maintain the optimal viscosity of the molten glass. Finally, the glass strip is pulled down at a uniform speed by multiple pairs of traction rollers 22 of the lower traction mechanism, while a laser thickness gauge monitors the thickness in real time, forming a feedback closed loop to ensure the production of ultra-thin electronic glass with uniform thickness and no defects.

[0049] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
