Description

Technical Field

[0001] This invention relates to the field of electronic fiberglass cloth technology, and in particular to an airflow isolation device for lamp tubes in electronic fiberglass cloth surface treatment machines. Background Technology

[0002] In the CCD vision inspection process of electronic fiberglass cloth surface treatment machines, the inspection lamp (such as LED or fluorescent lamp) is a key component for the inspection of electronic fiberglass cloth. However, existing lamps generally have problems such as attracting insects, especially in nighttime environments, where flying insects (such as moths, mosquitoes, and flies) will gather around the light source, and their corpses, excrement, wing fragments, etc., can easily fall onto the surface of the electronic fiberglass cloth, thus causing cloth surface contamination.

[0003] Currently, in the surface treatment of electronic fiberglass cloth, physical interventions are generally used to reduce flying insects, such as regular spraying and sealing doors and windows. However, the workshop space is large, and the flying insects are small, so these methods cannot effectively reduce the impact of flying insects on the cloth surface. In addition, ordinary protective covers are used to isolate flying insects, but this method reduces the light transmittance of the lamps, thus affecting the detection accuracy of the electronic fiberglass cloth; furthermore, there are problems such as poor heat dissipation and shortened lamp life due to unreasonable protective cover structure.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an airflow isolation device for lamp tubes in electronic fiberglass cloth surface treatment machines, which can effectively isolate insect pests from contaminating the electronic fiberglass cloth.

[0006] This invention provides an airflow isolation device for lamp tubes in an electronic fiberglass cloth surface treatment machine, comprising an air pipe and an air supply device. The air pipe is installed on the frame of the lamp tube in the electronic fiberglass cloth surface treatment machine, and multiple air nozzles are spaced apart on the air pipe. The air supply device is connected to the air pipe through a pipe to supply gas into the air pipe, and the gas is ejected through the air nozzles to form an air curtain for isolating the lamp tube.

[0007] In this invention, the air tube is mainly used to spray gas to form an air curtain to isolate the lamp tube, thereby keeping pollutants such as flying insects away from the lamp tube. The air tube can be installed in a suitable position such as the frame of the lamp tube in the electronic fiberglass cloth surface treatment machine. There are no strict restrictions on the way the air tube is installed, as long as it is convenient to form an air curtain that can effectively isolate pollutants such as flying insects. For example, the air tube can be arranged around the outer periphery of the lamp tube.

[0008] Multiple air nozzles are spaced apart on the trachea, with nozzle orifices ranging from 0.5 to 1 mm and spacing between adjacent nozzles from 5 to 15 cm. Furthermore, the nozzles can be tilted outwards at an angle of 30 to 60 degrees. These nozzles form an outward-radiating air curtain barrier, preventing approaching flying insects from getting closer to the lamp tube, while simultaneously blowing away insect carcasses and other contaminants from the outside of the lamp tube and the surface of the electronic fiberglass cloth.

[0009] The air pipe is connected to the air supply device via a pipeline. The air supply device supplies gas into the air pipe through the pipeline, and the gas is ejected through the nozzle of the air pipe to form an air curtain. The air supply device can be the compressed air system of the surface treatment machine. In addition, valves can be installed on the pipeline to regulate the gas flow rate.

[0010] Furthermore, an insect-repellent coating is provided on the surface of the trachea. The insect-repellent coating is formed by applying the insect-repellent coating to the surface of the trachea and then curing it. The insect-repellent coating is mainly made of the following components in parts by weight: 5-10 parts of insect-repellent slow-release agent, 40-50 parts of water-based acrylic resin, 1-3 parts of silane coupling agent, and 10-20 parts of diol.

[0011] Specifically, the preparation method of the insect repellent sustained-release agent includes: mixing the insect repellent component with a sodium alginate / calcium chloride mixed solution, then adding chitosan solution, ultrasonically treating, centrifuging, and drying.

[0012] In this invention, the insect-repellent components include eugenol and allyl hexoxyacetate, with a mass ratio of eugenol to allyl hexoxyacetate of (2-4):1. Studies have shown that eugenol and allyl hexoxyacetate can form a good synergistic insect-repellent effect, effectively causing flying insects in the CCD vision detection environment of the electronic fiberglass cloth surface treatment machine to stay away from the lamp tube.

[0013] The preparation method of sodium alginate / calcium chloride mixed solution includes: adding calcium chloride solution dropwise to sodium alginate solution under stirring conditions, followed by ultrasonic treatment; wherein, the concentration of sodium alginate solution is 0.5-1 mg / mL, the pH value of sodium alginate solution is 4-5, the concentration of calcium chloride solution is 0.3-0.6 mg / mL, the dropping rate is 1-2 mL / min, the stirring speed is 400-600 r / min, and the ultrasonic treatment time is 5-10 min.

[0014] The preparation method of chitosan solution includes: adding chitosan to glacial acetic acid solution, stirring and adjusting the pH value; wherein the mass content of glacial acetic acid solution is 1-2%, the concentration of chitosan solution is 0.4-0.8 mg / mL, and the pH value of chitosan solution is 5-6.

[0015] When preparing the insect repellent slow-release agent, the chitosan solution can be added at a rate of 1-2 mL / min; the mass ratio between the insect repellent component, sodium alginate, calcium chloride, and chitosan can be 1:(3-5):(0.8-1.2):(0.5-1.5); the ultrasonic treatment time is 5-10 min; and the particle size of the insect repellent slow-release agent is 200-400 nm.

[0016] The above-mentioned insect repellent slow-release agent uses chitosan and sodium alginate as carrier materials to encapsulate the insect repellent components, which can be slowly released to exert a continuous insect repellent function, thus helping to reduce the application frequency of the insect repellent coating.

[0017] In this invention, the silane coupling agent can be KH-560, which can improve the adhesion of the insect repellent coating to the tracheal surface.

[0018] In this invention, the diol can be dipropylene glycol or tripropylene glycol, which can not only serve as a solvent for other components, but also help to improve the sustained effect of the insecticidal components.

[0019] The insect repellent coating is formed by applying the above-mentioned insect repellent coating to the surface of the trachea and then curing it. The coating thickness can be 40-60 µm, the curing temperature can be 70-90 ℃, and the curing time can be 10-15 min.

[0020] The airflow isolation device of this invention forms a dynamic air curtain barrier that radiates outward through the air tube. This not only prevents flying insects in the environment from getting closer to the lamp tube, but also blows away contaminants on the outside of the lamp tube and the surface of the electronic fiberglass cloth. This method physically isolates the lamp tube from the light source while ensuring that the detection optical path of the electronic fiberglass cloth is not affected, thus effectively avoiding contamination of the electronic fiberglass cloth surface. In addition, by setting an insect-repellent coating on the surface of the air tube, flying insects are further prevented from approaching the lamp tube and the electronic fiberglass cloth, achieving a good and continuous insect-repellent effect and greatly ensuring the product quality of the electronic fiberglass cloth.

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.

[0027] Example 1 Combination Figure 1 As shown, this embodiment provides an airflow isolation device for lamp tubes in an electronic fiberglass cloth surface treatment machine, including an air pipe 1 and an air supply device 2. The air pipe 1 is installed on the frame of the lamp tube 5 in the electronic fiberglass cloth surface treatment machine. Multiple air nozzles 3 are spaced apart on the air pipe 1. The air supply device 2 is connected to the air pipe 1 through a pipe 4 to supply gas to the air pipe 1. The gas is ejected through the air nozzles 3 to form an air curtain for isolating the lamp tube 5.

[0028] The air duct 1 is mainly used to spray gas to form an air curtain to isolate the lamp tube 5, thereby keeping pollutants such as flying insects away from the lamp tube 5. The air duct 1 can be installed in a suitable position such as the frame of the lamp tube 5 of the electronic fiberglass cloth surface treatment machine. There are no strict restrictions on the setting of the air duct 1, as long as it is convenient to form an air curtain that can effectively isolate pollutants such as flying insects. For example, the air duct 1 can be arranged around the outer periphery of the lamp tube 5.

[0029] Multiple nozzles 3 are spaced apart on the trachea 1. The nozzle diameter of the nozzle 3 can be 0.5-1 mm, and the spacing between adjacent nozzles 3 can be 5-15 cm. Furthermore, the nozzles 3 can be tilted outwards at an angle of 30-60 degrees. In this embodiment, the nozzle diameter is 0.5 mm, the spacing between adjacent nozzles 3 is 5 cm, and the tilt angle is 45 degrees. The nozzles 3 form an outward-radiating air curtain barrier, preventing approaching flying insects from getting closer to the lamp tube 5, while simultaneously blowing away insect carcasses and other contaminants from the outside of the lamp tube 5 and the surface of the electronic fiberglass cloth 6.

[0030] Air pipe 1 is connected to air supply device 2 via pipe 4. Air supply device 2 supplies gas to air pipe 1 through pipe 4. The gas is ejected through nozzle 3 to form an air curtain. Air supply device 2 can be a compressed air system of a surface treatment machine. In addition, a valve can be installed on pipe 4 to adjust the gas flow rate.

[0031] The airflow isolation device in this embodiment forms a dynamic air curtain barrier that radiates outward through the air pipe 1. This not only prevents flying insects in the environment from getting closer to the lamp tube 5, but also blows away contaminants on the outside of the lamp tube 5 and the surface of the electronic fiberglass cloth 6. This method prevents flying insects from getting close to the light source through physical isolation, while ensuring that the detection optical path of the electronic fiberglass cloth is not affected, thus effectively avoiding contamination of the electronic fiberglass cloth surface.

[0032] Example 2 This embodiment is an improvement on Embodiment 1. The improvement involves preparing an insect-repellent coating on the trachea surface of Embodiment 1, as detailed below: 1. Preparation of insect repellent coating Sodium alginate was dissolved in deionized water to prepare a 1 mg / mL sodium alginate solution, and then the pH was adjusted to 5.

[0033] At a stirring speed of 500 r / min, 0.5 mg / mL of calcium chloride solution was added dropwise to the above sodium alginate solution at a dropping rate of 1 mL / min, followed by ultrasonic treatment for 10 min to obtain a sodium alginate / calcium chloride mixed solution.

[0034] Chitosan was added to a 1% (w / w) glacial acetic acid solution, stirred, and then the pH was adjusted to 5 to obtain a chitosan solution with a concentration of 0.5 mg / mL.

[0035] Eugenol and allyl hexoxyacetate were mixed at a mass ratio of 3:1 to form the anthelmintic component. The anthelmintic component was added to the sodium alginate / calcium chloride mixed solution. The mass ratio of the anthelmintic component, sodium alginate, calcium chloride, and chitosan was controlled to be 1:4:1:1. After stirring and mixing, the chitosan solution was added. After ultrasonic treatment for 10 min, the mixture was centrifuged and dried to obtain the anthelmintic sustained-release agent.

[0036] The insect repellent coating is prepared by mixing 8 parts of the above-mentioned insect repellent slow-release agent, 45 parts of water-based acrylic resin, 2 parts of silane coupling agent KH-560 and 15 parts of dipropylene glycol.

[0037] 2. Preparation of insect-repellent coating The above-mentioned insect repellent coating was applied to the trachea surface of Example 1 with a coating thickness of 50 µm, and then cured at 80 °C for 10 min to form an insect repellent coating on the trachea surface.

[0038] Compare with Example 1 The airflow isolation device of Example 1 was used as a control.

[0039] Compare with Example 2 Except for the fact that the anthelmintic component is eugenol, the rest is the same as in Example 2.

[0040] Compare with Example 3 Except for the use of allyl hexoxyacetate as the anthelmintic component, the rest is the same as in Example 2.

[0041] Compare with Example 4 Except for replacing dipropylene glycol in Example 2 with ethanol, the rest is the same as in Example 2.
