Description

Technical Field

[0001] This invention relates to the field of liquid crystal panel processing technology, specifically to an edge sealing device for liquid crystal panel processing. Background Technology

[0002] LCD panel edge-sealing equipment is a crucial piece of equipment in the LCD manufacturing process. Its main function is to precisely process and seal the edges of LCD panels. Utilizing high-precision cutting and grinding technology, this equipment ensures smooth and neat substrate edges, effectively preventing micro-cracks or damage caused by edge defects during subsequent assembly. The edge-sealing process typically involves the application of hot-melt edge sealant, which not only helps strengthen the structural strength of the substrate but also significantly improves its durability. Furthermore, the edge-sealing equipment is equipped with an advanced automated control system, enabling highly efficient and repeatable operations, greatly improving production efficiency and product quality. The LCD manufacturing process is extremely complex, and any flaw in the details can lead to quality problems in the final product. Substrate edge processing, as a key step, is undeniably important. Traditional manual processing methods can no longer meet the demands of modern high-efficiency production; therefore, edge-sealing equipment has emerged. This equipment, through precise mechanical control and advanced material application, ensures the flawless edges of every LCD panel.

[0003] However, existing edge-sealing equipment for LCD panel processing still faces several pressing issues in practical applications. First, current equipment typically only seals single LCD panels, resulting in low production efficiency and an inability to meet the rapid processing demands of assembly lines. In large-scale production environments, the limitations of single-panel processing become particularly pronounced. To improve efficiency, manufacturers are forced to increase the number of machines, which not only increases operational complexity but also significantly raises production costs. Second, the adhesive application stage in the edge-sealing process demands extremely high precision. Existing equipment often requires a high-precision adhesive application system to ensure edge-sealing quality when filling the sealing adhesive. While high-precision adhesive application equipment can guarantee the edge-sealing quality of LCD panels, its high cost is a significant burden for small and medium-sized manufacturers. Many SMEs are forced to choose lower-precision equipment due to their inability to afford the high investment costs, thus sacrificing product quality to some extent. Furthermore, the automation level of existing edge-sealing equipment needs improvement. Although some equipment is equipped with automated control systems, the intelligence and stability of these systems still require further enhancement. In actual operation, equipment may malfunction due to environmental factors or operational errors, affecting the continuity and stability of production. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an edge-sealing device for LCD panel processing. This device has the advantages of being able to quickly perform edge-sealing processing on LCD panels while achieving high-precision adhesive application at a low cost. It solves the problems of low edge-sealing efficiency, inability to adapt to assembly line production, and high cost of existing LCD panel edge-sealing equipment.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned goal of rapid edge sealing of LCD panels while simultaneously achieving high-precision adhesive application at a lower cost, this invention provides the following technical solution: An edge sealing device for LCD panel processing, comprising a conveyor table and an LCD panel. The LCD panel is arranged along the conveying direction of the conveyor table. Solid strip-shaped sealing adhesive is symmetrically arranged on both sides of the conveyor table, and both the LCD panel and the sealing adhesive move synchronously with the conveyor table. Several side rollers are also arranged at both ends of the conveyor table, and the side rollers symmetrically press the sealing adhesive into the two sides of the LCD panel. Several pressing rollers are also arranged above the LCD panel, and the two ends of the pressing rollers are mounted on the conveyor table.

[0008] Preferably, the sealing adhesive also has an embedded iron wire inside, and an induction heating module is provided on the conveying platform. The induction heating module is arranged along the conveying direction of the conveying platform, and the sealing adhesive and the LCD panel pass through the induction heating module. The pressing rollers are provided on both sides of the induction heating module. When the sealing adhesive passes through the induction heating module, the induction heating module generates an alternating magnetic field and heats the iron wire, thus heating the sealing adhesive.

[0009] Preferably, one end of the induction heating module is an input end and the other end is an output end. The pressing roller on one side of the output end of the induction heating module is connected to a cooling module, and the cooling module fills the pressing roller with circulating coolant.

[0010] Preferably, the refrigeration module is configured in two or more groups, and the two or more groups of refrigeration modules are respectively located at both ends of the conveyor.

[0011] Preferably, a detachable guide strip is provided on the outside of the sealing adhesive, and the guide strip is provided with a protruding structure. The protruding structure is inserted into the interior of the sealing adhesive, and the protruding structure is fixedly connected to the wire.

[0012] Preferably, four or more take-up rollers are also provided on both sides of the conveyor table. Each pair of take-up rollers is symmetrically arranged on both sides of the conveyor table. The take-up roller on the feeding side of the conveyor table has sealing glue and guide strips wound inside, and the take-up roller on the discharging side of the conveyor table has guide strips wound inside. When discharging, the take-up roller on the discharging side of the conveyor table pulls the guide strips out of the sealing glue and rewinds them.

[0013] Preferably, the outer surface of the guide strip is designed with anti-slip texture, and the guide strip is made of heat-resistant material.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides an edge-sealing device for liquid crystal panel processing, which has the following advantages:

[0016] 1. This edge-sealing device for LCD panel processing, through the coordinated use of a conveyor structure, a sealing glue structure, a side roller structure, and a pressing roller structure, avoids the step of applying glue to the LCD panel during edge-sealing processing, which results in low edge-sealing efficiency and high cost due to the high precision requirements of the equipment itself. Instead, this edge-sealing device for LCD panel processing directly extrudes pre-processed sealing glue into the LCD panel, thereby significantly reducing processing difficulty and cost and improving processing efficiency.

[0017] 2. This edge-sealing device for LCD panel processing, through the combined use of a conveyor structure and a sealing adhesive structure, overcomes the limitations of traditional edge-sealing technologies. Traditional equipment can only seal one LCD panel at a time, unable to process multiple panels simultaneously. This device can process multiple LCD panels simultaneously, and after edge-sealing, the sealed LCD panels can be directly transported along the conveyor to the next processing stage or conveyor equipment. This structure enables seamless production line integration. This continuous production process avoids the handling and storage time associated with traditional LCD panel edge-sealing equipment, optimizing handling equipment, reducing costs, and preventing potential damage to LCD panels during handling. Furthermore, the device's structure significantly improves LCD panel production efficiency, allowing it to be integrated into a wider range of automated systems, thus contributing to more advanced automated and integrated production lines.

[0018] 3. This edge-sealing device for LCD panel processing, through the combined use of an induction heating module, a wire structure, a sealing adhesive structure, a cooling module, and a pressure roller structure, offers advantages over traditional edge-sealing methods. Traditional methods, which often involve more complex edge-sealing processes, directly extrude the sealing adhesive into the LCD panel. The induction heating module then generates an alternating magnetic field, heating the wire within the adhesive and softening it to adhere to the inner surface of the LCD panel. This heating method directly heats the adhesive through the LCD panel, creating a concentrated and uniform heat source that rapidly softens the adhesive. Furthermore, because it eliminates the need to penetrate the substrate, heat loss during induction heating is reduced, resulting in greater energy efficiency. In contrast, traditional heating methods require inserting the heating equipment into the LCD panel. Traditional heating methods can cause physical damage or thermal stress to the LCD panel. Induction heating, however, heats the sealant through the substrate, avoiding direct contact and reducing the risk of substrate damage. The sealant is then cooled and cured by a pressure roller supplied with coolant. The pressure roller quickly removes heat, allowing the softened sealant to solidify rapidly. This significantly shortens the entire processing cycle and improves production efficiency. Simultaneously, the rapid cooling of the coolant enables the sealant to solidify quickly in its softened state, forming a strong adhesive interface. This improves the bonding strength between the sealant and the LCD panel, increasing product reliability and durability. Furthermore, traditional methods may require waiting for natural cooling or using uneven cooling methods, while this structure allows the cooling process to continue on the production line, reducing downtime and improving equipment efficiency.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5An edge-sealing device for LCD panel processing includes a conveyor table 1 and an LCD panel 2. The LCD panel 2 is arranged along the conveyor table 1 in the conveying direction, enabling a continuous and automated production process. This design ensures that the LCD panel 2 can move smoothly and continuously through each processing step, avoiding the inconvenience and inefficiency of manual handling. Through the conveyor table 1, the substrate can automatically pass through all edge-sealing steps, thus achieving a high-efficiency production line, reducing interference from human operation, and lowering the error rate. Solid strips of sealing adhesive 3 are symmetrically arranged on both sides of the conveyor table 1, and both the LCD panel 2 and the sealing adhesive 3 move synchronously with the conveyor table 1. The symmetrical arrangement of the sealing adhesive 3 on both sides of the conveyor table 1 and the synchronous movement of the LCD panel 2 and the sealing adhesive 3 ensure that the sealing adhesive 3 is evenly adhered to the edge of the LCD panel 2. This design reduces alignment and positioning errors, ensuring that the sealing adhesive 3 accurately adheres to the edge of the substrate, improving the edge-sealing quality. This symmetrical design ensures uniform pressure on the sealing adhesive 3 during the sealing process, resulting in a more consistent sealing effect and reducing sealing failures caused by positional misalignment. Several side rollers 4 are also installed at both ends of the conveyor table 1. The purpose of the side rollers 4 is to ensure that the sealing adhesive 3 is evenly pressed into the sides of the LCD panel 2 during its movement. The side rollers 4 provide the necessary pressure to press the sealing adhesive 3 into the substrate edge, ensuring a tight bond between the sealing adhesive 3 and the substrate edge. This prevents the sealing adhesive 3 from shifting during movement, ensuring the accuracy and quality of the sealing. The side rollers 4 symmetrically press the sealing adhesive 3 into the sides of the LCD panel 2. Several pressing rollers 5 are also installed above the LCD panel 2. The combined use of the side rollers 4 and the pressing rollers 5 ensures that the sealing adhesive 3 adheres evenly to the edges and surface of the LCD panel 2. The side rollers 4 press the sealing adhesive 3 into the substrate side, and the pressing rollers 5 further ensure that the sealing adhesive 3 is tightly adhered to the substrate surface. This multi-pressure design ensures a stronger and more uniform bond between the sealing adhesive 3 and the substrate, avoiding air bubbles or poor adhesion during the sealing process and improving the sealing quality. The pressure rollers 5 are mounted on the conveyor table 1 at both ends. Compared to traditional technologies that require applying adhesive to the LCD panel 2 during edge sealing, resulting in lower sealing efficiency and higher costs due to the high precision requirements of the equipment, this edge sealing device for LCD panel 2 directly applies pre-processed sealing adhesive 3 into the LCD panel 2, thus avoiding the adhesive application step and significantly reducing processing difficulty and costs while improving processing efficiency.Compared to traditional edge-sealing equipment, which can only process one LCD panel 2 at a time and cannot process multiple LCD panels 2 simultaneously, this edge-sealing device for LCD panel 2 can process multiple LCD panels 2 simultaneously. After edge-sealing, the edge-sealed LCD panels 2 can be directly transported along the conveyor 1 to the next processing stage or conveyor equipment. This structure enables seamless connection of the production line. This continuous production process avoids the handling and storage time generated during the processing of traditional LCD panel 2 edge-sealing equipment. It not only optimizes the handling equipment and reduces costs, but also avoids damage to the LCD panels 2 that may occur during handling. Furthermore, the structure of this device significantly improves the production efficiency of LCD panels 2, allowing it to be integrated into a wider range of automated systems. This helps to achieve more advanced automated and integrated production lines.

[0030] Please see Figure 1 , Figure 4 , Figure 5 , Figure 8The sealing adhesive 3 also incorporates an embedded iron wire 6. The alternating magnetic field generated by the induction heating module 7 induces eddy currents within the iron wire 6, causing it to heat up rapidly. This non-contact heating method avoids direct heating of the LCD panel 2, reducing the risk of substrate damage. The rapid heating of the iron wire 6 under the influence of eddy currents transfers heat to the sealing adhesive 3, causing it to soften quickly and achieving efficient edge sealing. Simultaneously, the heat generated by the iron wire 6 under the influence of eddy currents is evenly distributed within the sealing adhesive 3, ensuring uniform softening and close adhesion to the inner surface of the LCD panel 2, improving edge sealing quality and bonding strength. Induction heating concentrates heat around the iron wire 6, effectively controlling the heating area and temperature, avoiding overheating or uneven heating, and improving processing quality. Furthermore, induction heating is more energy-efficient than traditional heating methods because heat is generated directly within the sealing adhesive 3, reducing conduction losses and improving energy utilization efficiency. An induction heating module 7 is installed on the conveyor table 1. Induction heating heats the iron wire 6 through an alternating magnetic field, without direct contact with the LCD panel 2, thus avoiding physical damage to the substrate surface. Non-contact heating reduces the concentration of thermal stress on the substrate, mitigating thermal deformation and stress concentration that may be caused by uneven heating of the substrate. Simultaneously, the induction heating module 7 can rapidly generate high temperatures, quickly heating the iron wire 6 embedded in the sealant 3, thereby rapidly softening the sealant 3 and improving sealing efficiency. Rapid heating significantly shortens the heating time, thus reducing the processing time for each LCD panel 2 and improving the overall efficiency of the production line. Furthermore, induction heating can create a uniform thermal field within the sealant 3, causing it to soften uniformly and ensuring that it adheres evenly to the inner surface of the LCD panel 2, improving the bonding effect. The induction heating module 7 is positioned along the conveying direction of the conveyor table 1, and the sealant 3 and LCD panel 2 are connected by the induction heating module 7 along the conveying direction, ensuring continuous heating of the sealant 3 and LCD panel 2 during movement, making the sealing process seamless and reducing downtime. Continuous processing design improves the automation level of the production line, reduces manual intervention, and increases production efficiency and consistency. Simultaneously, the frame adhesive and LCD panel 2 move synchronously on the conveyor belt, ensuring that the heating and edge-sealing processes are synchronized. This guarantees that the frame adhesive 3 softens and adheres to the LCD panel 2 at the optimal time, ensuring edge-sealing quality. An induction heating module 7 is installed along the conveying direction to ensure that the frame adhesive 3 remains continuously heated throughout the entire processing flow, reducing potential downtime and waiting time, and improving the overall efficiency of the production line. Pressure rollers 5 are installed on both sides of the induction heating module 7. These rollers apply pressure after the frame adhesive 3 softens, ensuring that the frame adhesive 3 adheres tightly to the inner surface of the LCD panel 2, improving the edge-sealing adhesion and preventing the frame adhesive 3 from falling off or poorly adhering. The uniform pressure applied by the pressure rollers 5 maintains the shape of the LCD panel 2 and the frame adhesive 3, preventing deformation or detachment during cooling and curing, and ensuring consistent product form.Simultaneously, pressure rollers 5 are installed on both sides to ensure that the sealing adhesive 3 receives uniform pressure, improving the sealing quality and avoiding poor adhesion or air bubbles caused by uneven force, thus ensuring the stability of the sealing. When the sealing adhesive 3 passes through the induction heating module 7, the module generates an alternating magnetic field, causing the wire 6 to heat the adhesive 3. One end of the induction heating module 7 is the input end, and the other end is the output end. A cooling module 8 is connected to the pressure roller 5 on the output end side of the module 7. The cooling module 8 fills the pressure roller 5 with circulating coolant. The input and output ends clearly define the start and end of the heating process, helping to precisely control the heating time and temperature, improving the controllability and precision of the processing. The cooling module 8 on the output end side of the induction heating module 7 can quickly cool the softened sealing adhesive 3, allowing it to solidify and set rapidly, shortening the processing cycle and ensuring the sealing quality. Filling the pressure roller 5 with circulating coolant ensures the continuity and stability of the cooling process, avoiding the impact of temperature fluctuations on the sealing quality, improving processing consistency and production efficiency. The cooling modules 8 are configured in two or more sets, each positioned at one end of the conveyor table 1. The segmented cooling by multiple cooling modules 8 ensures that the sealing adhesive 3 cools and cures evenly throughout the cooling process, preventing localized overheating or underheating that could affect the sealing quality. Multiple cooling modules 8 can operate simultaneously, accelerating cooling, reducing downtime, improving overall production efficiency, and ensuring the efficient operation of the production line. Furthermore, the separate placement of the cooling modules at both ends of the conveyor table 1 ensures that the sealing adhesive 3 at different locations on the conveyor table 1 cools evenly, preventing poor adhesion or edge deformation caused by uneven cooling, and improving product consistency and quality.

[0031] Please see Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8The sealing adhesive 3 is also equipped with a detachable guide strip 9 on its outer side. This detachable guide strip 9 ensures accurate positioning and guidance of the sealing adhesive 3 during processing. Pressing the guide strip 9 with the side roller 4 makes it easier to press the sealing adhesive 3 into the LCD panel 2. Furthermore, the guide strip 9 provides stable support and guidance, preventing the sealing adhesive 3 from shifting or bending during conveying and pressing, thus ensuring the consistency and precision of the sealing quality. The detachable design also facilitates equipment maintenance and cleaning, improving ease of use. The guide strip 9 has a raised structure 10 that inserts into the sealing adhesive 3 and is fixedly connected to the wire 6. This ensures that the wire 6 remains in a fixed position during heating and cooling. This design prevents the wire 6 from moving when the sealing adhesive 3 softens or hardens, thus ensuring uniform heating and stable adhesion of the sealing adhesive 3. Meanwhile, the raised structure 10 can pull out the wire 6 together when the guide strip 9 is disassembled, simplifying subsequent processing steps and improving production efficiency. The outer surface of the guide strip 9 is designed with anti-slip texture, which can reduce the friction between the guide strip 9 and the side roller 4, reduce slippage, and improve operating efficiency and safety. At the same time, the guide strip 9 is made of heat-resistant material, which can maintain structural stability in high-temperature environments and will not deform or be damaged due to temperature rise, thereby ensuring the normal operation of the equipment and the sealing quality. The heat-resistant material is generally a flexible high-temperature material, such as silicone rubber, fluororubber FKM, or polytetrafluoroethylene PTFE. Four or more take-up rollers 11 are also set on both sides of the conveyor table 1. Setting multiple take-up rollers 11 can ensure the synchronous movement and stable winding of the sealing glue 3 and the guide strip 9 during the processing. The take-up rollers 11 are symmetrically arranged in pairs on both sides of the conveyor table 1. The take-up roller 11 on the feed side of the conveyor table 1 contains the sealing adhesive 3 and the guide strip 9, while the take-up roller 11 on the discharge side of the conveyor belt contains the guide strip 9. The symmetrical arrangement of the take-up rollers 11 ensures that the force on both sides of the conveyor belt is uniform, avoiding excessive force on one side that could cause the conveyor belt or LCD panel 2 to shift position. This prevents the conveyor belt from running off-center or the LCD panel 2 from becoming unstable due to uneven force on one side. At the same time, the symmetrical design increases the overall stability of the equipment, ensuring that the conveyor belt and LCD panel 2 maintain smooth operation during the edge sealing process, reducing processing errors caused by vibration or shaking. The sealing adhesive 3 and LCD panel 2 must move synchronously during the conveying process. The symmetrical arrangement of the take-up rollers 11 ensures that the sealing adhesive 3 and LCD panel 2 move synchronously, avoiding positional shift of the sealing adhesive 3 due to inconsistent conveying speeds, which would affect the edge sealing accuracy. The symmetrical arrangement helps to keep the relative position of the sealing adhesive 3 and the LCD panel 2 consistent during the sealing process, ensuring that the sealing adhesive 3 can be accurately attached to the edge of the LCD panel 2, improving processing accuracy and product quality; when unloading, the winding roller 11 on the unloading side of the conveyor 1 pulls the guide strip 9 out of the sealing adhesive 3 and rewinds it.This design automatically peels the guide strip 9 from the sealing adhesive 3 after edge sealing, reducing the need for manual intervention, improving the automation level of the production line, and thus increasing production efficiency and consistency. Automatic peeling and rewinding of the guide strip 9 makes the production process more continuous and smooth, reducing downtime caused by manual operation and improving production efficiency. While the guide strip 9 mainly serves a positioning and support function within the sealing adhesive 3, if it is not peeled off in time after edge sealing, it may affect the adhesion between the sealing adhesive 3 and the LCD panel 2. Timely peeling of the guide strip 9 ensures the adhesion strength and effect between the sealing adhesive 3 and the LCD panel 2.

[0032] Working Principle: During operation, the equipment is set up on the production line for processing LCD panels 2, with an unsealed LCD panel 2 placed at one end of the feed conveyor 1. During processing, the LCD panel 2 moves along the conveyor 1, while the take-up rollers 11 at both ends of the conveyor 1 drive the sealing adhesive 3 to move synchronously along the conveyor 1 with the LCD panel 2. As the sealing adhesive 3 moves along the conveyor 1, it is squeezed by the side rollers 4, causing it to be pressed into the LCD panel 2. Subsequently, both ends of the LCD panel 2 are pressed by the pressure rollers 5, which press the LCD panel 2 firmly onto the conveyor 1, ensuring that the upper and lower surfaces of the sealing adhesive 3 inside the LCD panel 2 are tightly attached to the inner surface of the LCD panel 2.

[0033] When the LCD panel 2, with the sealing adhesive 3 sandwiched between it, passes through the induction heating module 7, the alternating magnetic field generated by the induction heating module 7 induces a current within the passing wire 6. This induced current forms a loop current called eddy current within the wire 6. These eddy currents are mainly concentrated on and near the surface of the wire 6, a phenomenon known as the skin effect. As the frequency increases, the skin effect becomes more pronounced, and the current mainly flows on the surface of the wire 6. Because the wire 6 has its own resistance, the eddy currents overcome this resistance when passing through it, thus converting into heat energy. According to Joule's law, this causes the wire 6 to heat up rapidly. The heat generated in this process is proportional to the resistance of the wire 6, the intensity of the eddy currents, and the frequency of the current. Due to the high frequency of high-frequency alternating current, the generated eddy currents and heat are very concentrated and rapid, thus heating the wire 6 to a very high temperature in a very short time. The heat generated by the wire 6 quickly softens the sealant 3, allowing its upper and lower surfaces to adhere completely to the inner surface of the LCD panel 2. This heating method directly heats the sealant 3 inside the LCD panel 2, creating a concentrated and uniform heat source within the sealant 3, causing it to soften rapidly. Furthermore, since it eliminates the need to insert the heating equipment into the substrate, heat loss during induction heating is reduced, resulting in greater energy efficiency. In contrast, traditional heating methods require inserting the heating equipment into the LCD panel 2, potentially causing physical damage or thermal stress. Induction heating, by heating the sealant 3 through the substrate, avoids direct contact and reduces the risk of substrate damage. The risk is mitigated by the fact that the LCD panel 2 with softened sealant 3 then passes through a pressure roller 5 circulated with coolant. This pressure roller 5 quickly solidifies the softened sealant 3, ensuring it adheres firmly to the inner surface of the LCD panel 2. The rapid cooling of the coolant allows the sealant 3 to solidify quickly in its softened state, forming a strong adhesive interface. This improves the bonding strength between the sealant 3 and the LCD panel 2, increasing product reliability and durability. Furthermore, traditional methods may require waiting for natural cooling or using uneven cooling methods, while this structure allows the cooling process to continue continuously on the production line, reducing downtime and improving equipment efficiency. When the sealed LCD panel 2 moves to the take-up roller 11 on the output side of the conveyor 1, the take-up roller 11, connected to the guide strip 9, pulls out the guide strip 9 attached to the sealant 3. Simultaneously, the protruding structure 10 pulls out the wire 6 embedded in the sealant 3.
