Description

Technical Field

[0001] The utility model relates to the technical field of glass product processing, in particular to an anaerobic optical glue curing device. Background Art

[0002] Anaerobic optical adhesive is a special type of adhesive used primarily in applications requiring curing in an oxygen-free environment. By spin-coating or spraying a layer of anaerobic optical adhesive onto the product surface, the high transmittance and low haze of the optical adhesive enhance the product's optical performance while protecting the surface.

[0003] In existing technology, anaerobic optical adhesive can only be applied by pressing two pieces of product together to form a closed space. The product is then irradiated with a UVLED light source. After absorbing the light energy, the photoinitiator undergoes a series of complex reactions, ultimately generating protonic acid, which initiates the entire light-hardening reaction. For anaerobic optical adhesive, the curing conditions make process development more difficult, and it cannot be verified with other relatively advanced processes. In addition, under non-pressing conditions, the glue cannot be cured when exposed to air and requires vacuum treatment. The product with anaerobic optical adhesive on the surface is placed in a vacuum chamber to evacuate the chamber. After ensuring that there is no oxygen in the chamber, UV LED light curing is performed. The vacuum is generated by pumping gas out of the chamber with a vacuum pump, reducing the pressure in the chamber to a very low level.

[0004] Based on this, a new solution is needed. Utility Model Content

[0014] The anaerobic optical glue curing device provided by this utility model has the following beneficial effects: A nitrogen supply pipeline is used to input nitrogen into the interior of the curing chamber through a nitrogen inlet, and the nitrogen is used to inflate the curing chamber. Once the nitrogen enters the curing chamber, it displaces the oxygen inside the chamber and is discharged through the nitrogen inlet, thereby creating an oxygen-free environment within the chamber for curing the glue.

[0015] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only embodiments of the present invention. Those skilled in the art can obtain other drawings based on the provided drawings without inventive work.

[0016] Figure 1 Shown is a structural schematic diagram of an anaerobic optical glue curing device provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0017] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate exemplary embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0019] Figure 1 The figure shows the structure of the anaerobic optical glue curing device provided by one embodiment of the present invention. Figure 1 As shown, the anaerobic optical glue curing device provided by the present invention includes a curing box body 100, a UV curing lamp (not shown in the figure) and a nitrogen supply pipe (not shown in the figure), wherein the curing box body 100 is a rectangular or square box body, consisting of four side panels, a top plate and a bottom plate, the UV curing lamp is arranged inside the curing box body 100 and fixed on the top plate 110 of the curing box body 100, a nitrogen inlet 130 is opened on the first side panel 120 of the curing box body 100, and a nitrogen outlet 150 is opened on the second side panel 140 of the curing box body 100, the first side panel 120 and the second side panel 140 are arranged opposite to each other, and when in use, the nitrogen supply pipe is connected to the nitrogen inlet 130. Therefore, the nitrogen supply pipeline inputs nitrogen into the interior of the curing box body through the nitrogen inlet, and the curing box body is inflated with nitrogen. After the nitrogen enters the interior of the curing box body, it squeezes out the oxygen inside the curing box body and is discharged through the nitrogen inlet, thereby forming an oxygen-free environment inside the curing box body for curing the glue. Compared with the method of using a vacuum cavity to ensure oxygen-free, the cost of using nitrogen curing is lower, and it is more efficient and more compatible. At the same time, using nitrogen injection to cure anaerobic optical glue can increase the number of products cured in a single time and improve efficiency. Figure 1 In the example shown, the first side panel and the second side panel are respectively the left side panel and the right side panel of the curing box body. Those skilled in the art will understand that the first side panel and the second side panel can also be respectively the front side panel and the rear side panel of the curing box body, as long as the two side panels are in relative positions, and the present application is not limited to this.

[0020] Furthermore, in one embodiment of the present invention, the height of the nitrogen inlet 130 on the first side panel 120 is higher than the height of the nitrogen outlet 150 on the second side panel 140. Specifically, the height of the nitrogen inlet 130 relative to the bottom is higher than the height of the nitrogen outlet 150 relative to the bottom. The nitrogen inlet 130 is located at the top of the curing chamber. Taking advantage of nitrogen's lower density, it allows nitrogen to flow from the top to the bottom of the curing chamber. After entering the curing chamber, the nitrogen gradually sinks, displacing oxygen within the chamber downward, which is then discharged from the chamber body through the nitrogen outlet 150. The nitrogen outlet 150 is located at the bottom of the curing chamber. This low-level exhaust arrangement allows for more efficient removal of oxygen from the bottom of the chamber, ensuring a gradual oxygen-free environment within the chamber, meeting the requirements for glue curing. Because air has a higher density than nitrogen, the upper position of the nitrogen inlet allows nitrogen to gradually replace oxygen within the chamber, creating a stable oxygen-free environment. This ensures that the glue cures under oxygen-free conditions, thereby improving the curing effect and quality. At the same time, the top-down flow of nitrogen helps to form a uniform nitrogen atmosphere within the curing chamber. This even gas distribution ensures that every area within the curing chamber is under conditions suitable for glue curing, thereby improving curing uniformity and efficiency. Furthermore, the presence of nitrogen outlet 150 at the bottom effectively prevents oxygen from accumulating at the bottom of the curing chamber. Since oxygen is denser than nitrogen, it will preferentially exit the bottom, ensuring that the atmosphere within the curing chamber is more suitable for glue curing.

[0021] Furthermore, in one embodiment of the present invention, the first side panel 120 includes a first fixed portion 1201 and an air inlet guide portion 1202, the air inlet guide portion 1202 is rotatably connected to the first fixed portion 1201, and the nitrogen inlet port 130 is provided on the air inlet guide portion 1202. The role of nitrogen is to provide an oxygen-free environment during the curing process to avoid bubbles on the surface of the glue and uneven curing effects. The guide plate can evenly distribute nitrogen from the air inlet 130 into the curing box to ensure that the gas is not concentrated in a certain area, thereby avoiding inconsistent curing effects caused by uneven airflow; in addition, during the entry of the airflow, excessive gas impact may cause the fluidity of the glue to be disturbed, affecting the final curing quality. The guide plate effectively reduces the impact of gas impact on the glue. The air inlet guide plate is rotatably connected to the fixed part, allowing the operator to adjust the angle and position of the guide plate according to actual needs. This flexibility can optimize the direction and method of nitrogen inflow according to different curing tasks or product requirements, thereby improving the adaptability and efficiency of the curing process. At the same time, regular inspection and cleaning of the guide plate can prevent the accumulation of dust and impurities and maintain airflow stability. The rotating design makes the air inlet guide plate easier to maintain and clean.

[0022] Furthermore, in one embodiment of the present invention, the bottom of the curing chamber body 100 is a stretchable structure. The third side panel 160 of the curing chamber body 100 includes a second fixed portion 1601 and a stretchable portion 1602. The stretchable portion 1602 is integrally formed with the bottom panel 170 of the curing chamber body 100 to form the stretchable structure. A silicone ring 180 is attached to the edge of the bottom panel 170, and a handle 190 is provided outside the stretchable portion 1602. The stretchable structure of the bottom makes the loading and unloading process of the product more efficient and convenient. Operators can easily pull the bottom panel to load and unload the product, reducing operation time and labor intensity. The silicone ring attached to the edge of the bottom panel has a certain degree of stickiness, ensuring that the bottom panel is tightly connected to the curing chamber body, preventing air leakage and maintaining the airtightness of the cavity. This seal helps prevent the loss of UV light and improves the curing effect. By ensuring the airtightness of the cavity, the UV LED light source can more effectively illuminate the product surface, ensuring uniformity and effectiveness of the curing, thereby improving overall curing efficiency. The design of the hand-pull part makes the pulling and pulling operation of the bottom plate simpler and smoother, allowing operators to complete the task more easily, reducing operational difficulty and possible misoperation.

[0023] Furthermore, in one embodiment of the present invention, a first tracheal joint installed at the nitrogen inlet 130 and a second tracheal joint installed at the nitrogen outlet 150 are also included. In an embodiment of the present invention, the first tracheal joint installed at the nitrogen inlet 130 and the second tracheal joint installed at the nitrogen outlet 150 play an important role. By adopting the first tracheal joint and the second tracheal joint, the stability and sealing of the gas connection are ensured, the possibility of gas leakage is reduced, the flow stability of nitrogen during the curing process is guaranteed, and the influence of gas leakage on the curing quality is effectively prevented. At the same time, the use of the tracheal joint provides the user with convenient operation, making installation and disassembly very convenient, which reduces installation time and operation complexity and improves production efficiency. In addition, the design of the tracheal joint eliminates the need for welding. The welding process usually requires special equipment and technology, while the welding-free feature of the tracheal joint makes installation easier, which reduces the technical requirements and costs in the production process. The design of the tracheal joint also eliminates the need for pipe flaring. The traditional piping method may require the pipe to be flared to achieve connection, while the use of the tracheal joint allows direct connection, reducing the processing steps and related errors. The reliability of gas connections is crucial to the proper functioning of the system, especially during the curing process, which requires precise control of gas flow. By employing advanced, high-performance gas fittings, the stability of the entire system is significantly improved. Regular inspection and replacement of gas fittings ensures optimal system performance over time. The design of the fittings simplifies installation and removal, making system maintenance and overhaul more convenient.

[0024] Furthermore, in one embodiment of the present invention, the curing chamber body 100 is made of acrylic. The acrylic sheet has a light transmittance exceeding 92%, meaning the UV LED light source can efficiently penetrate the sheet and illuminate the product surface, ensuring uniform illumination during the curing process. This high light transmittance contributes to a more uniform curing effect, thereby improving product quality and consistency. Furthermore, acrylic exhibits excellent weather resistance, effectively resisting the effects of long-term UV exposure. This is particularly important for UV curing devices, as the curing process generates a certain amount of UV radiation. Acrylic maintains its performance and appearance, thereby extending the lifespan of the curing chamber. Furthermore, the acrylic sheet's high surface hardness makes it less susceptible to scratches and wear, ensuring the curing chamber maintains its excellent appearance and functionality over extended use. Although the temperatures generated during UV LED curing are relatively low, the acrylic material's excellent high-temperature performance effectively handles these temperature fluctuations, ensuring the acrylic material maintains stability during the curing process and preventing deformation or damage caused by temperature changes. Acrylic is easy to cut and process, making the manufacture and customization of curing boxes more convenient. Curing boxes can be customized in various shapes and sizes to meet various curing needs. Acrylic's smooth surface resists dust accumulation, making cleaning and maintenance relatively simple, helping to maintain the curing box in good condition and maintain operating efficiency. Compared to other materials like glass, acrylic is lighter, reducing the overall weight of the curing box. This not only facilitates transportation and installation, but also reduces the burden on the equipment, further improving ease of operation.

[0025] The anaerobic optical glue curing device provided by the present invention adopts an external nitrogen pipeline connected to a closed curing chamber; the main connection method between the external nitrogen pipeline and the left side of the closed curing chamber is through a trachea quick connector, and a buffer baffle is installed at the nitrogen inlet of the curing chamber; the external air outlet pipeline is connected to the right side of the closed curing chamber; a UV curing lamp is installed at the top of the closed curing chamber; the bottom of the closed curing chamber is a stretchable structure, which is convenient for loading and unloading products. When in use, the air inlet on the left side of the curing box body is connected to the external nitrogen pipeline using a trachea connector. After the product is sprayed / spin-coated, the operator pulls out the pull-out plate, puts in the finished glue-dispensed product, closes the pull-out plate, and ensures that the entire chamber is in a closed state; then, the nitrogen inlet is opened, nitrogen is injected, and the UV LED light source is turned on at the same time. After a specific time according to the glue curing parameters and the UV LED light energy, the UV LED light source and the air inlet nitrogen pipeline are turned off; finally, the operator pulls out the pull-out plate, takes out the finished glue-dispensed and cured product, and repeats this process.

[0026] The anaerobic optical glue curing device provided by the utility model has the following advantages:

[0027] 1. Based on the relationship between the density of oxygen and nitrogen, the nitrogen inlet is placed at the top of the curing box body, and the air at the nitrogen outlet is placed at the bottom of the curing box body. The density of air is greater than that of nitrogen. After the nitrogen enters the curing box body, it will squeeze out the oxygen inside the curing box body and be discharged through the nitrogen outlet, thus forming an oxygen-free environment inside the curing box body for glue curing.

[0028] 2. By adding an air inlet guide plate at the nitrogen inlet to guide the nitrogen at the inlet, it can be ensured that the gas can be pressed down steadily, and the fluidity of the glue on the product surface will not be affected due to excessive gas. The guide plate can effectively and steadily reduce the nitrogen at the inlet.

[0029] 3. The product loading and unloading adopts the method of pulling out the bottom plate, which is convenient for loading and unloading. A silicone ring is attached to the edge of the bottom plate. The silicone ring has a certain viscosity and connects the bottom plate to the curing box body so that it can be effectively connected during curing, ensuring the airtightness of the cavity and improving the curing efficiency of the UV LED light source.

[0030] 4. The air inlet and outlet use air pipe joints with a series of advantages such as advanced structure, good performance, easy use, no need for welding, no need to expand the pipe, etc., which can effectively ensure air tightness.

[0031] 5. The entire device is made of acrylic material. Acrylic material has crystal-like transparency and a light transmittance of over 92%. It has high transparency. The UV LED light source can efficiently penetrate the acrylic board to illuminate the product surface, thereby curing the glue. The acrylic board has excellent weather resistance, high surface hardness and surface gloss, as well as good high-temperature performance. The UV LED lamp generates a small amount of temperature during curing, and the acrylic material can increase the service life of the device.
