Description

Technical Field

[0001] The utility model belongs to the technical field of glue curing equipment, and in particular relates to a deep UV glue curing device. Background Art

[0002] UV glue curing device is a device that uses the radiation energy of ultraviolet (UV) light to cause a chemical reaction in the photosensitizer in the glue during the glue curing process, thereby achieving rapid curing of the glue. This curing method has the advantages of fast curing speed, high production efficiency, and environmental protection and pollution-free, so it has been widely used in industrial production. However, the existing UV glue curing device has some technical limitations, especially when curing deep glue, the effect is not ideal. The prior art mainly uses an ultraviolet curing light source to irradiate the surface of the glue from above the product to start the curing process. However, this simple top-to-bottom irradiation method has obvious limitations for thicker glue layers.

[0003] Since ultraviolet light gradually attenuates during propagation, when the light penetrates a thicker glue layer, its irradiation intensity is greatly reduced. This results in insufficient ultraviolet energy received by the bottom of the glue layer, which cannot effectively initiate the chemical reaction of the photosensitizer and achieve complete curing. Therefore, when using the existing technology to cure deep glue, the bottom of the glue often does not cure completely or even does not cure at all.

[0004] In addition, the existing technology does not effectively control the intensity of the UV curing light source. This means that during the curing process, the intensity of the UV light cannot be accurately adjusted according to factors such as the thickness of the glue layer, the type of glue, and the curing requirements. This may not only lead to energy waste, but also affect the curing effect and even pose a potential threat to product quality.

[0005] Through the above analysis, the problems and defects of the prior art are as follows: when the existing UV glue curing device is used to cure deep glue, the bottom of the glue is often not completely cured or even not cured at all; and the irradiation intensity of the curing light source cannot be effectively controlled, which easily leads to energy waste and may also affect the curing effect.

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0027] like Figure 1 As shown, the deep UV glue curing device provided by the embodiment of the utility model includes a supporting frame 1, a conveying device 2 and a curing furnace.

[0028] The conveying device 2 is installed on the upper end of the support frame 1, and the curing furnace is fixedly connected to the support frame 1. The conveying device 2 passes through the middle position of the curing furnace. The curing furnace includes an upper shell 3 and a lower shell 4. The upper shell 3 is provided with a first ultraviolet curing light source 6 through a fixing seat 5, and the lower shell 4 is provided with a second ultraviolet curing light source 7 through a fixing seat 5. The first ultraviolet curing light source 6 and the second ultraviolet curing light source 7 can allow ultraviolet rays to irradiate the product from above and below at the same time, thereby greatly increasing the irradiation range and penetration depth of ultraviolet rays. For a thicker glue layer, ultraviolet rays from both the upper and lower directions can penetrate the glue more evenly, ensuring that the bottom of the glue layer can also receive sufficient ultraviolet energy, thereby achieving complete curing.

[0029] The first ultraviolet curing light source 6 and the second ultraviolet curing light source 7 are respectively connected to a power regulator 8 through a connecting line, and the power regulator 8 is connected to a control panel 9 through a connecting line, and the control panel 9 is embedded on the outer side of the upper shell 3. The irradiation intensity of the first ultraviolet curing light source 6 and the second ultraviolet curing light source 7 can be accurately adjusted by the power regulator 8 under the control of the control panel 9. In the actual curing process, the irradiation intensity of the ultraviolet light can be flexibly adjusted according to factors such as the thickness of the glue layer, the type of glue, and the curing requirements. This can not only ensure that the glue is fully cured, but also avoid energy waste and improve production efficiency.

[0030] In addition, the control of the power regulator 8 by the control panel 9 can also realize the automatic management of the curing process. The user can automatically adjust the irradiation intensity of the ultraviolet light according to the preset parameters or real-time feedback signals, thereby realizing the precise control of the curing process. This helps to reduce the error of human operation and improve the consistency of product quality.

[0031] like Figure 2 As shown, the first ultraviolet curing light source 6 and the second ultraviolet curing light source 7 in the embodiment of the utility model both include a plurality of ultraviolet lamp tubes 10, a lamp tube holder 11 and a water cooling device 12. A plurality of equally spaced mounting grooves 13 are provided on one side of the lamp tube holder 11. The plurality of ultraviolet lamp tubes 10 are respectively mounted in the corresponding mounting grooves 13. The water cooling device 12 is fixedly connected to the other side of the lamp tube holder 11. By providing a plurality of ultraviolet lamp tubes 10, the irradiation area and intensity of ultraviolet rays can be increased, thereby improving the curing efficiency. The design of the mounting groove 13 on the lamp tube holder 11 makes the installation and replacement of the lamp tube more convenient. At the same time, the introduction of the water cooling device 12 can effectively reduce the heat generated by the lamp tube during operation, thereby ensuring the stability and service life of the lamp tube.

[0032] Preferably, the water cooling device 12 in the embodiment of the utility model comprises a water cooling box 14 and a coil 15, the inner side of the water cooling box 14 is filled with a heat conducting medium 18, the coil 15 is installed in the inner side of the water cooling box 14, and the two ends of the water cooling box 14 are respectively embedded with a water inlet 16 and a water outlet 17 connected to the coil 15, and the water inlet 16 and the water outlet 17 are connected to the external circulating cooling pipeline. The heat conducting medium 18 and the coil 15 structure in the water cooling box 14 can efficiently conduct and dissipate heat, take away the heat through the circulating cooling pipeline, and ensure that the lamp tube runs at the optimal temperature.

[0033] Preferably, the upper shell 3 and the lower shell 4 in the embodiment of the utility model are both equipped with a reflective panel 19 on the inner side, and the reflective panel 19 surrounds the outer side of the first ultraviolet curing light source 6 and the second ultraviolet curing light source 7. The reflective panel 19 can reflect the ultraviolet rays that are not absorbed by the glue, so that they are irradiated onto the glue layer again, thereby improving the utilization rate of the ultraviolet rays and the curing effect. This design is particularly suitable for thicker glue layers, and can ensure that the bottom of the glue layer can also receive sufficient ultraviolet energy.

[0034] like Figure 3 As shown, the conveying device 2 in the embodiment of the utility model includes a driving motor 20, a support shaft 21 and a conveying belt 22. The driving motor 20 is fixed at one end of the supporting frame 1. A supporting shaft 21 is rotatably installed at both ends of the supporting frame 1. Two conveying belts 22 are installed between the two supporting shafts 21. The two ends of the two supporting shafts 21 are respectively meshed with the inner side of the conveying belt 22 through gears. The automatic conveying of the product is realized by the combination of the driving motor 20, the supporting shaft 21 and the conveying belt 22. The driving motor 20 drives the supporting shaft 21 and the conveying belt 22 to rotate through gear transmission, thereby driving the product to smoothly pass through the curing furnace, improving production efficiency, reducing labor costs, and realizing a continuous and automated production process.

[0035] Preferably, a driving gear is installed at the output end of the driving motor 20 in the embodiment of the utility model, and a driven gear is connected to the outer end of the support shaft 21 installed at the same end of the support frame 1 as the driving motor 20, and the driving gear is meshed with the driven gear. This gear transmission method has the advantages of high transmission efficiency, stable transmission ratio, compact structure, etc., which can ensure the stable operation and precise control of the conveying device 2.

[0036] The working principle of the utility model is as follows: when the utility model is used, the operator places the product to be cured on the conveying device 2, so that the two ends of the product are placed on two conveyor belts 22 respectively, to ensure that the product can pass through the curing furnace smoothly. According to factors such as the thickness of the glue layer of the product, the type of glue and the curing requirements, the appropriate ultraviolet irradiation intensity is set through the control panel 9. The device is started, and the driving motor 20 starts to work, and the support shaft 21 and the conveyor belt 22 are driven to rotate through the gear transmission, thereby driving the product into the curing furnace. At the same time, the first ultraviolet curing light source 6 and the second ultraviolet curing light source 7 begin to emit ultraviolet rays to irradiate the glue layer of the product. The ultraviolet rays penetrate the glue layer and trigger the chemical reaction of the photosensitizer, thereby achieving the curing of the glue. Due to the use of multiple ultraviolet lamps 10 and water cooling devices 12, the ultraviolet irradiation intensity is accurately controlled, and the working temperature of the lamp tubes remains stable, ensuring the consistency and efficiency of the curing effect. The reflective panel 19 can reflect the ultraviolet rays that are not absorbed by the glue, so that it is irradiated on the glue layer again, thereby improving the utilization rate of the ultraviolet rays and the curing effect. When the product completely passes through the curing furnace, the curing process ends, and the curing effect of the product is checked. If necessary, the irradiation intensity can be adjusted through the control panel 9 for re-curing. The utility model adopts a double-layer light source design, a power regulator and a control panel 9, effectively solves the problem that deep glue cannot be completely cured in the prior art, improves the penetration ability of ultraviolet rays and the irradiation uniformity, and realizes precise control of the irradiation intensity, thereby improving the curing effect of deep glue, improving product quality, and promoting the further development of UV glue curing technology.
