Description

Technical Field

[0001] This utility model relates to the field of fiber laser technology, and in particular to a temperature control device for adhesive in a fiber coating machine. Background Technology

[0002] In the laser manufacturing process, the critical fiber coating step uses low-refractive-index adhesive, which is prone to crystallization at low ambient temperatures. Simultaneously, low temperatures result in poor adhesive flow, making it difficult for air bubbles to escape. This can cause the fiber coating layer to overheat and become shiny, severely impacting the coating effect and yield.

[0003] In related technologies, the glue heating method of optical fiber coating machines usually involves wrapping a resistance heating wire around the glue bottle and heating the glue bottle through the resistance heating wire. This method has problems such as uneven heating, difficulty in controlling the heating temperature, and inconvenience in operation, and has limited effect on optical fiber coating.

[0004] Therefore, it is necessary to design a new adhesive heating device for optical fiber coating machines that can achieve uniform heating of the adhesive, easy control of the heating temperature, and convenient operation of the heating process. Utility Model Content

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.

Therefore, the directional terms used are for the purpose of explaining and understanding this application, and not for limiting this application.

[0028] In the laser manufacturing process, the critical fiber coating step uses low-refractive-index adhesive, which is prone to crystallization at low ambient temperatures. Simultaneously, low temperatures result in poor adhesive flow, making it difficult for air bubbles to escape. This can cause the fiber coating layer to overheat and become shiny, severely impacting the coating effect and yield.

[0029] In related technologies, the glue heating method of optical fiber coating machines usually involves wrapping a resistance heating wire around the glue bottle and heating the glue bottle through the resistance heating wire. This method has problems such as uneven heating, difficulty in controlling the heating temperature, and inconvenience in operation, and has limited effect on optical fiber coating.

[0030] Therefore, it is necessary to design a new adhesive heating device for optical fiber coating machines that can achieve uniform heating of the adhesive, easy control of the heating temperature, and convenient operation of the heating process.

[0031] To solve the above-mentioned technical problems, this utility model provides a fiber optic coating machine adhesive temperature control device 100, which will be described in detail below.

[0032] Please see Figure 1 , Figure 1 This is a schematic diagram of a fiber optic coating machine adhesive temperature control device provided in an embodiment of this utility model, as shown below. Figure 1 As shown, the adhesive temperature control device 100 of the optical fiber coating machine includes: a flexible heating plate 110, a digital display temperature controller 120, and a power supply 130.

[0033] The flexible heating plate 110 is electrically connected to the digital display temperature controller 120. The flexible heating plate 110 is used to wrap the glue bottle 210 of the optical fiber coating machine 200 and heat the glue bottle 210. The power supply 130 is electrically connected to the digital display temperature controller 120. The power supply 130 is used to supply power to the digital display temperature controller 120, and the digital display temperature controller 120 is used to control the heating temperature of the flexible heating plate 110.

[0034] In this embodiment, the digital display temperature controller 120 provided in this embodiment can be pre-set with multiple different temperature control buttons, each button corresponding to a different temperature control parameter, such as buttons corresponding to temperature control parameters such as 5℃, 10℃, 20℃, etc. By selecting the corresponding temperature button on the digital display temperature controller 120, the heating temperature of the flexible heating plate 110 can be controlled to reach the temperature corresponding to the selected temperature button, thereby achieving the purpose of uniformly heating the glue bottle 210 wrapped by the flexible heating plate 110.

[0035] Optionally, the digital display temperature controller 120 provided in this embodiment may also be equipped with a temperature hysteresis button and temperature control upper and lower limit buttons, using a hysteresis method to control the temperature, which has high control accuracy and good stability. Additionally, the digital display temperature controller 120 provided in this embodiment may also be equipped with a heating status indicator light, which can display the working status of the digital display temperature controller 120 in real time.

[0036] Specifically, the temperature buttons provided in this embodiment can be virtual buttons displayed on the screen of the digital display temperature controller 120, or physical buttons on the digital display temperature controller 120. The number of temperature buttons can be set according to actual application needs, and no specific limit is made to the number of temperature buttons here.

[0037] In this embodiment of the utility model, the power supply 130 may include an AC power supply and a DC power supply, as long as it can supply power to the digital display temperature controller 120 so that it can work normally, and no specific limitation is made here.

[0038] Thus, by using this embodiment of the invention, the glue bottle 210 of the optical fiber coating machine 200 is wrapped with a flexible heating plate 110. Compared to heating the glue bottle 210 by wrapping a resistance heating wire around it, this embodiment of the invention can achieve uniform heating of the glue bottle 210 of the optical fiber coating machine 200. Furthermore, the heating operation is easy to control and the heating process is convenient, effectively improving the efficiency of heating the glue in the glue bottle 210 of the optical fiber coating machine 200.

[0039] In some embodiments, to ensure the curling performance of the flexible heating plate 110 provided in this embodiment and to achieve the purpose of wrapping the glue bottle 210 of the optical fiber coating machine 200, the flexible heating plate 110 provided in this embodiment can be a silicone rubber heating plate. Thus, the silicone rubber heating plate can tightly wrap the outer surface of the glue bottle 210, thereby achieving the purpose of uniformly heating the glue bottle 210.

[0040] The silicone rubber provided in this embodiment refers to a rubber whose main chain is composed of alternating silicon and oxygen atoms, with two organic groups typically attached to each silicon atom. Commonly used silicone rubbers are mainly composed of siloxane linkages containing methyl groups and a small amount of vinyl groups. The introduction of phenyl groups can improve the high and low temperature resistance of silicone rubber, while the introduction of trifluoropropyl and cyano groups can improve its temperature and oil resistance. Specifically, silicone rubber exhibits excellent low-temperature resistance, generally remaining functional at -55°C, and reaching -73°C after the introduction of phenyl groups. Simultaneously, silicone rubber also demonstrates outstanding heat resistance, capable of long-term operation at 180°C, and maintaining elasticity for weeks or longer at temperatures slightly above 200°C, while also withstanding instantaneous temperatures above 300°C. Furthermore, silicone rubber has excellent air permeability, boasting the highest oxygen permeability among synthetic polymers. Thus, the use of a heating plate made of silicone rubber can effectively ensure the high and low temperature resistance of the flexible heating plate 110 provided in this embodiment, and can also maintain its elasticity after repeated use, avoiding frequent replacement of the flexible heating plate 110 and effectively reducing the replacement cost of the optical fiber coating machine adhesive temperature control device 100 provided in this embodiment.

[0041] As an optional embodiment, to improve the safety of the adhesive temperature control device 100 for the optical fiber coating machine provided in this embodiment, the surface of the silicone rubber heating plate provided in this embodiment can be made of an insulating layer material. The insulating layer material effectively prevents electric shock and leakage during use, thus effectively ensuring the safety of the adhesive temperature control device 100 for the optical fiber coating machine provided in this embodiment.

[0042] Specifically, the insulating layer material provided in this embodiment may include glass fiber. Glass fiber is an inorganic non-metallic material mainly made from six minerals—pyrophyllite, quartz sand, limestone, dolomite, borocalcite, and boromagnesia—through high-temperature melting, drawing, winding, and weaving processes. This ensures the insulation, heat resistance, and corrosion resistance of the insulating layer. Furthermore, glass fiber has high mechanical strength and can be reused repeatedly, further reducing the replacement cost of the adhesive temperature control device 100 for the optical fiber coating machine provided in this embodiment.

[0043] In this embodiment of the invention, to achieve uniform heating of the glue bottle 210, the silicone rubber heating plate provided in this embodiment can be uniformly arranged with nickel-chromium alloy resistance wires inside, and the digital display temperature controller 120 is electrically connected to the nickel-chromium alloy resistance wires. Thus, by uniformly arranging the nickel-chromium alloy resistance wires inside the silicone rubber heating plate provided in this embodiment, the digital display temperature controller 120 can control the nickel-chromium alloy resistance wires to heat the silicone rubber heating plate uniformly, thereby achieving the purpose of uniformly heating the glue bottle 210 through the silicone rubber heating plate.

[0044] In this embodiment of the utility model, in order to achieve precise temperature control of the silicone rubber heating plate, the silicone rubber heating plate provided in this embodiment may also be equipped with an NTC thermistor (not shown in the figure). The digital display temperature controller 120 is electrically connected to the nickel-chromium alloy resistance wire through the NTC thermistor, and controls the heating temperature of the nickel-chromium alloy resistance wire through the NTC thermistor.

[0045] Among them, the NTC thermistor (Negative Temperature Coefficient) is a thermistor manufactured using ceramic technology with manganese, cobalt, nickel, and copper oxides as the main materials. These metal oxide materials all possess semiconductor properties. Furthermore, the most important aspect of the NTC thermistor is its lifespan. It can withstand various high-precision, high-sensitivity, high-reliability, ultra-high temperature, and high-pressure tests while maintaining stable operation for a long time. Thus, the NTC thermistor provided in this embodiment not only enables precise temperature control of the silicone rubber heating plate but also eliminates concerns about its lifespan, further reducing the replacement cost of the adhesive temperature control device 100 for the optical fiber coating machine provided in this embodiment.

[0046] As an optional embodiment, the silicone rubber heating plate provided in this embodiment can be set as a naturally rolled heating plate, such as a heating plate with elastic properties. In this way, when wrapping different glue bottles 210, it is only necessary to break open the naturally rolled heating plate, place the glue bottle 210 within the curling range of the naturally rolled heating plate, and then release the naturally rolled heating plate. The naturally rolled heating plate can automatically wrap the glue bottle 210 according to its own elastic properties, effectively improving the efficiency of wrapping the glue bottle 210.

[0047] Furthermore, to effectively ensure the silicone rubber heating plate provided in this embodiment effectively wraps around the glue bottle 210, the silicone rubber heating plate provided in this embodiment may also be provided with a fixing structure (not shown in the figure). The fixing structure is used to tightly wrap the silicone rubber heating plate around the outer surface of the glue bottle 210. Optionally, the fixing structure provided in this embodiment can be Velcro. In this way, through the fixing structure, the silicone rubber heating plate can be fixed when it tightly wraps around the outer surface of the glue bottle 210, thereby effectively ensuring the wrapping effect of the silicone rubber heating plate provided in this embodiment on the glue bottle 210, and thus effectively ensuring uniform heating of the glue bottle 210.

[0048] In summary, this utility model embodiment provides a glue temperature control device for an optical fiber coating machine, including a flexible heating plate, a digital display temperature controller, and a power supply. The flexible heating plate is electrically connected to the digital display temperature controller. The flexible heating plate is used to wrap the glue bottle of the optical fiber coating machine and heat the glue bottle. The power supply is electrically connected to the digital display temperature controller. The power supply is used to supply power to the digital display temperature controller, and the digital display temperature controller is used to control the heating temperature of the flexible heating plate.

[0049] By employing the embodiments of this utility model, the following beneficial effects can be achieved:
