Description

Technical Field

[0001] This utility model belongs to the field of glass processing and surface treatment technology, specifically a glass production coating and curing device. Background Technology

[0002] In the glass coating production process, the performance of the coating curing equipment directly affects the coating quality and production efficiency. Currently, various coating curing technologies based on high-temperature furnace heating or hot air circulation have emerged on the market, but these technologies still have many shortcomings in practical applications, affecting the uniformity and stability of the coating.

[0003] For example, Chinese invention patent (publication number: CN104676458B, publication date: November 23, 2016) discloses an LED anti-reflective and anti-glare glass lampshade and its manufacturing method. This technology uses a high-temperature furnace to heat the coated glass lampshade as a whole to achieve stable curing of the film. However, this method, relying on overall high-temperature furnace heating, consumes a lot of energy and the temperature distribution is not uniform enough, easily leading to uneven local thermal stress in the film layer, which may cause cracking or peeling. Furthermore, this solution does not address effective control of solvent evaporation during the coating process, which may lead to a decrease in film uniformity and affect optical performance.

[0004] For example, Chinese invention patent (publication number: CN111410434B, publication date: February 28, 2023) discloses a preheating method and equipment for producing coated glass. This technology uses hot air to preheat the glass substrate and the coating solution separately, and then uses hot air again for post-heating treatment after coating to improve the adhesion and light transmittance of the film layer. Although it improves the bonding force between the film layer and the substrate, the open-loop hot air circulation heating method has low heat utilization, and changes in ambient temperature and humidity may interfere with the stability of the curing process. At the same time, this technology lacks effective means to adjust the internal stress of the film layer during the curing process, which may lead to increased brittleness and insufficient weather resistance of the film layer.

[0005] The aforementioned problems indicate that existing coating curing equipment still has certain limitations in terms of energy consumption, temperature control accuracy, film adhesion stability, and weather resistance, making it difficult to meet the demands of modern industry for continuous and intelligent production of high-quality coated glass. Therefore, there is an urgent need to develop a new type of glass production coating curing equipment to solve these problems and improve coating efficiency and finished product quality. Utility Model Content

[0007] To achieve the above objectives, the specific technical solution adopted by this utility model is as follows:

[0008] This invention provides a glass coating and curing apparatus, comprising a heating component, a solvent recovery component, and a stress adjustment component. The heating component is used to uniformly heat the coated glass; the solvent recovery component is located to the side of the heating component and is used to collect the solvent that evaporates during the coating process; the stress adjustment component is located below the heating component and is used to adjust the stress distribution inside the film layer during the coating process.

[0009] The heating assembly includes a heat-conducting plate and multiple heating units embedded within the heat-conducting plate. The heating units are arranged in an array, and each heating unit is connected to an external power source via a wire. The surface of the heat-conducting plate has several micropores with a diameter ranging from 0.1 mm to 0.5 mm, used to uniformly transfer heat to the coating surface. A heat insulation layer made of ceramic fiber material with a thickness of 3 mm to 5 mm is fixed to the bottom of the heat-conducting plate to reduce heat loss downwards.

[0010] Preferably, the solvent recovery assembly includes a collection chamber and an adsorption unit. The collection chamber is located on one side of the heat-conducting plate and is connected to the coating area via a gas guide pipe. The adsorption unit is located inside the collection chamber and consists of multiple layers of activated carbon filters, with each layer of activated carbon filters fixedly connected by slots. An exhaust port is provided at the top of the collection chamber, and a one-way valve is installed inside the exhaust port to prevent backflow of outside air.

[0011] Preferably, the stress adjustment assembly includes an adjustment plate and multiple elastic supports. The adjustment plate is located below the heat-conducting plate and is fixedly connected to the heat-conducting plate by bolts. The elastic supports are evenly distributed on the bottom surface of the adjustment plate. Each elastic support consists of a spring and a support column. The spring is sleeved on the outside of the support column, and its two ends are fixedly connected to the adjustment plate and the base, respectively. The support column is made of stainless steel, with a diameter of 8mm to 12mm and a height of 20mm to 30mm.

[0012] Preferably, the heat-conducting plate is provided with slide rails on both sides, the slide rails having an "I" shaped cross-section for use with the slider. The top of the slider is fixedly connected to the heat-conducting plate by screws, and the bottom is provided with rollers that match the grooves of the slide rails, allowing the heat-conducting plate to move smoothly on the slide rails.

[0013] Preferably, a temperature probe is provided at the front end of the heat-conducting plate, and the temperature probe is connected to a temperature controller via a wire. The temperature controller is fixedly installed on the outer casing of the device and is used to monitor and adjust the operating status of the heating unit in real time. The number of temperature probes is four to six, evenly distributed on the front edge of the heat-conducting plate.

[0014] Preferably, the bottom of the collecting chamber is provided with a drain port, which is connected to the storage tank via a pipe. The storage tank is equipped with a liquid level sensor, which is connected to an alarm via a signal line. When the liquid level reaches a preset value, the alarm sounds.

[0015] Preferably, the surface of the regulating plate is provided with multiple vent holes, the diameter of which is 1mm to 2mm, to balance the air pressure on the upper and lower sides of the regulating plate. A sealing strip is provided around the regulating plate, the sealing strip being made of silicone material with a thickness of 2mm to 3mm, to prevent heat loss from the edges.

[0016] Preferably, the outer surface of the spring of the elastic support member is coated with a high-temperature resistant coating with a thickness of 0.1 mm to 0.2 mm to improve the heat resistance of the spring. A ball joint is provided at the top of the support column, and the ball joint is threadedly connected to the bottom surface of the adjusting plate for easy disassembly and replacement.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] By setting up an array of heating units and heat-conducting plates, multiple heating units operate independently and the heat is evenly transferred to the coating surface through the heat-conducting plates, avoiding the problem of uneven heat distribution in traditional high-temperature furnace heating methods. The microporous design further improves the uniformity of heat transfer, while the insulation layer reduces heat loss downwards, thereby reducing overall energy consumption.

[0019] By incorporating a solvent recovery assembly, volatile solvents enter the collection chamber through a gas duct and are adsorbed by a multi-layer activated carbon filter, effectively reducing solvent pollution. The one-way valve design at the exhaust port prevents backflow of outside air, ensuring stable airflow within the collection chamber. The combined use of the drain port and storage tank enables centralized solvent processing, while the integration of a level sensor and alarm enhances operational safety and convenience.

[0020] By incorporating a stress-adjusting component, the elastic support can automatically adjust its support force according to stress changes within the film layer during the coating process, thereby alleviating the problem of internal stress concentration in the film layer. Ventilation holes on the adjustment plate balance the air pressure, while the sealing strip prevents heat loss, further enhancing the stability of the device.

[0021] The heat-conducting plate can move smoothly on the slide rail using the cooperation of the slide rail and slider, facilitating heating of the coating area at different locations. The combination of temperature probe and temperature controller enables precise control of the heating process, ensuring the stability of the coating quality.

[0022] In summary, this invention significantly improves the overall performance of the coating curing device by optimizing key processes such as heating, solvent recovery, and stress adjustment. It solves the problems of high energy consumption, insufficient temperature control accuracy, unstable film adhesion, and poor weather resistance in existing technologies, thus meeting the needs of modern industry for continuous and intelligent production of high-quality coated glass.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1As shown, this utility model provides a glass production coating curing device, which includes a heating component, a solvent recovery component, and a stress adjustment component. The core component of the heating component is a heat-conducting plate 1, with multiple heating units 2 embedded inside the heat-conducting plate 1, arranged in an array. Each heating unit 2 is connected to an external power source via a wire. The surface of the heat-conducting plate 1 has several micropores 3, with a diameter ranging from 0.1 mm to 0.5 mm, for uniform heat transfer. A heat insulation layer 4, made of ceramic fiber material and 3 mm to 5 mm thick, is fixed to the bottom of the heat-conducting plate 1 to reduce heat loss downwards. Slide rails 11 are provided on both sides of the heat-conducting plate 1. The slide rails 11 have an "I"-shaped cross-section. Slider blocks 12 are fixedly connected to the heat-conducting plate 1 by screws. Rollers are provided at the bottom of the sliders 12, and the rollers match the grooves of the slide rails 11, allowing the heat-conducting plate 1 to move smoothly on the slide rails 11.

[0032] The solvent recovery assembly is located on one side of the heating assembly and includes a collection chamber 5 and an adsorption unit. The collection chamber 5 is connected to the coating area via a gas guide pipe. The adsorption unit consists of multiple layers of activated carbon filters 6, with each layer fixedly connected by slots. An exhaust port 7 is located at the top of the collection chamber 5, and a one-way valve 8 is installed inside the exhaust port 7 to prevent backflow of outside air. A drain port 15 is located at the bottom of the collection chamber 5, and the drain port 15 is connected to a storage tank 16 via a pipe. A liquid level sensor is installed inside the storage tank 16, and the liquid level sensor is connected to an alarm via a signal line. When the liquid level reaches a preset value, the alarm sounds. Figure 3 As shown, the structural design of the collection chamber 5 can effectively separate volatile solvents and process them centrally.

[0033] The stress adjustment assembly is located below the heating assembly and includes an adjustment plate 9 and multiple elastic support members 10. The adjustment plate 9 is fixedly connected to the heat-conducting plate 1 by bolts. The elastic support members 10 are evenly distributed on the bottom surface of the adjustment plate 9. Each elastic support member 10 consists of a spring 19 and a support column 20. The spring 19 is sleeved on the outside of the support column 20, and its two ends are fixedly connected to the adjustment plate 9 and the base, respectively. The support column 20 is made of stainless steel, with a diameter of 8mm to 12mm and a height of 20mm to 30mm. The surface of the adjustment plate 9 has multiple vent holes 17, with a diameter of 1mm to 2mm, used to balance the air pressure on the upper and lower sides of the adjustment plate 9. A sealing strip 18, made of silicone material and 2mm to 3mm thick, is provided around the adjustment plate 9 to prevent heat loss from the edges. Figure 4 As shown, the design of the elastic support 10 can automatically adjust the support force according to the stress changes inside the membrane layer.

[0034] A temperature probe 13 is provided at the front end of the heat-conducting plate 1. The temperature probe 13 is connected to a temperature controller 14 via a wire. The temperature controller 14 is fixedly mounted on the outer casing of the device and is used to monitor and adjust the working status of the heating unit 2 in real time. There are four to six temperature probes 13, evenly distributed along the front edge of the heat-conducting plate 1. Figure 3 As shown, the cooperative structure of the slide rail 11 and the slider 12 enables the heat-conducting plate 1 to move smoothly on the slide rail 11, which facilitates heating of the coating area at different positions.

[0035] In practical use, the coated glass is first placed above the heat-conducting plate 1, and the heating unit 2 is activated for heating. Heat is evenly transferred to the coated surface through the micropores 3 on the heat-conducting plate 1. During the heating process, the temperature probe 13 monitors the temperature in real time and transmits the data to the temperature controller 14. The temperature controller 14 adjusts the working state of the heating unit 2 according to the set value to achieve precise temperature control. At the same time, the solvent volatilized during the coating process enters the collection chamber 5 through the gas guide pipe and is adsorbed by the multi-layer activated carbon filter 6. The treated gas is discharged through the exhaust port 7, while the condensed liquid flows into the storage tank 16 through the drain port 15. When the liquid level in the storage tank 16 reaches the preset value, the liquid level sensor triggers the alarm to sound, reminding the operator to clean the storage tank 16 in time.

[0036] During the coating curing process, stress concentration may occur within the film layer. This is where the stress adjustment component comes into play. The adjustment plate 9 is connected to the base via an elastic support 10. The spring 19 in the elastic support 10 automatically adjusts the support force according to changes in the internal stress of the film layer, thereby alleviating the stress concentration problem. Simultaneously, the vent holes 17 on the adjustment plate 9 balance the air pressure on both sides, while the sealing strip 18 effectively prevents heat loss from the edges, ensuring the stability of the entire device. Through the cooperation of the slide rail 11 and the slider 12, the heat-conducting plate 1 can move smoothly on the slide rail 11, facilitating heating of the coating area at different locations and further improving the flexibility and adaptability of the device.

[0037] This invention relates to a glass coating and curing device. By optimizing the design of the heating, solvent recovery, and stress adjustment components, it achieves uniform heat transfer, effective solvent recovery, and reasonable adjustment of the internal stress of the coating layer. The connections between the components are close and their cooperation is smooth, meeting the demands of modern industry for continuous and intelligent production of high-quality coated glass.

[0038] To enable those skilled in the art to fully understand and implement this utility model, the following detailed explanation of the operating principle and implementation steps of this utility model is provided in conjunction with specific application scenarios.

[0039] In actual production environments, glass coating curing equipment is installed at the rear end of the coating production line to heat and cure the glass substrate after the coating process. The entire process consists of the following key steps:

[0040] First, the coated glass substrate is placed above the heat-conducting plate 1, ensuring close contact between the glass surface and the heat-conducting plate 1. Then, the heating unit 2 is activated, and current is transmitted to it through wires, generating heat. The heat is conducted through the interior of the heat-conducting plate 1 and evenly distributed across its surface, subsequently transferred to the glass coating surface via micropores 3. The design of the micropores 3 allows for a uniform heat flow field on the coating surface, preventing localized overheating or insufficient temperature. Simultaneously, the temperature probe 13 monitors the temperature of the front edge of the heat-conducting plate 1 in real time and transmits the data to the temperature controller 14. The temperature controller 14 adjusts the operating state of the heating unit 2 according to a preset target temperature range, achieving precise temperature control. This design ensures that the temperature of the coating surface remains within a suitable curing range, effectively improving the adhesion and uniformity of the film layer.

[0041] Secondly, during the heating process, the volatile solvents in the coating solution evaporate due to the increased temperature. These volatile gases are introduced into the collection chamber 5 through the gas guide pipe. The multi-layer activated carbon filter 6 inside the collection chamber 5 adsorbs solvent molecules in the gas flow step by step, ensuring that the discharged gas meets environmental standards. A one-way valve 8 inside the exhaust port 7 prevents backflow of outside air, maintaining the stability of the airflow inside the collection chamber 5. Simultaneously, some solvent condenses into liquid within the collection chamber 5 and flows into the storage tank 16 through the drain port 15. When the liquid level in the storage tank 16 reaches a preset value, the level sensor triggers an alarm to sound, reminding operators to clean the storage tank 16 promptly. This design not only achieves effective recovery of volatile solvents but also reduces environmental pollution and improves production safety and sustainability.

[0042] Next, during the coating curing process, stress concentration may occur inside the film layer due to temperature changes and differences in material properties. At this point, the stress adjustment component comes into play. The adjustment plate 9 is connected to the base via an elastic support 10, and the spring 19 in the elastic support 10 can automatically adjust the support force according to changes in the internal stress of the film layer. When the internal stress of the film layer increases, the spring 19 is compressed and contracts, providing additional support; when the stress decreases, the spring 19 returns to its original shape, releasing excess pressure. This dynamic adjustment mechanism effectively alleviates the stress concentration problem inside the film layer, avoiding the risk of film cracking or detachment. Furthermore, the vents 17 on the adjustment plate 9 balance the air pressure on both sides, and the sealing strip 18 further prevents heat loss from the edges, ensuring the overall stability and energy-saving effect of the device.

[0043] Subsequently, to accommodate the heating requirements of different coating areas, the operator can move the heat-conducting plate 1 via the mating structure of the slide rail 11 and the slider 12. The roller at the bottom of the slider 12 matches the groove of the slide rail 11, allowing the heat-conducting plate 1 to slide smoothly on the slide rail 11. In this way, the position of the heat-conducting plate 1 can be flexibly adjusted to provide targeted heating to different areas of the glass substrate. This design significantly improves the adaptability of the device, making it particularly suitable for coating and curing processes on large-area or complex-shaped glass substrates.

[0044] Finally, the synergistic effect between the components throughout the curing process ensures the efficient operation of the device. For example, the heat insulation layer 4 effectively reduces heat loss downwards, thus lowering energy consumption; the combination of the temperature probe 13 and the temperature controller 14 enables real-time monitoring and precise control of the heating process; and the high-temperature resistant coating and spherical joint design of the elastic support 10 further enhance the reliability and ease of maintenance of the device.

[0045] In summary, through the specific implementation of the above steps, this invention achieves uniform heat transfer, effective solvent recovery, and reasonable adjustment of internal stress within the film layer. Close collaboration among the components ensures the high efficiency and stability of the coating curing process, meeting the demands of modern industry for continuous and intelligent production of high-quality coated glass.
