Description

Technical Field

[0001] This utility model relates to the field of glass sheet manufacturing technology, and in particular to a UV curing box and a glass sheet production line. Background Technology

[0002] During the bonding process of glass flat sheets, air bubbles can easily get mixed into the adhesive, affecting the bonding quality and the performance of the glass flat sheets. Existing curing equipment often struggles to simultaneously and efficiently complete defoaming and curing operations (generally using UV light sources for curing), resulting in low production efficiency and unstable product quality. Because defoaming and curing are performed in separate steps, the process is inefficient and time-consuming, and the step-by-step transfer process can easily lead to secondary contamination of the product.

[0003] Therefore, there is an urgent need to design a UV curing chamber and a glass sheet production line to solve the above problems. Utility Model Content

[0004] One objective of this invention is to provide a UV curing box that allows for the sequential defoaming and curing of adhesive within a single space, eliminating the need for adhesive transfer, thereby improving production efficiency and preventing secondary contamination of the product.

[0005] Another objective of this invention is to provide a glass sheet production line that integrates defoaming and curing operations into a UV curing chamber, thereby reducing operational complexity, saving on the number of devices required, lowering costs, and improving product quality.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] UV curing chamber, including:

[0008] The box has an internal storage space, and a door is provided on the front side of the box, which can open or close the storage space.

[0009] The vacuum assembly includes a vacuum pump and a gas pipe. The vacuum pump is installed on the outside of the housing, and one end of the gas pipe is connected to the accommodating space, while the other end is connected to the vacuum pump.

[0010] A stage is disposed within the aforementioned accommodating space, and the stage is used to hold the adhesive to be cured;

[0011] UV light source, at least the upper side of the above-mentioned box is provided with a UV light source;

[0012] A pressure relief valve is installed in the aforementioned enclosure and is configured to either close or connect the aforementioned accommodating space to the outside.

[0013] As an alternative, the UV curing chamber also includes heating tubes, with at least a plurality of such heating tubes arranged side by side on one side of the chamber interior.

[0014] As an optional solution, the vacuum assembly also includes a pressure sensor, which is installed in the housing and configured to monitor the air pressure in the accommodating space and communicate with the vacuum pump. The vacuum pump is configured to stop evacuating and maintain the vacuum for a preset time when the air pressure in the accommodating space drops to a first preset value.

[0015] As an optional solution, the vacuum assembly also includes an alarm device, which is installed in the housing and communicates with the pressure sensor. The alarm device is configured to issue an alarm signal when the value of the pressure sensor is lower than a second preset value.

[0016] As an alternative, the UV light source is positioned at the top of the accommodating space, and a reflector is provided on the upper side of the UV light source, the reflector being configured to reflect the upward-shielded light from the UV light source downwards.

[0017] As an alternative, the UV light source is positioned at the top of the aforementioned accommodating space and includes several sub-light sources arranged in a matrix.

[0018] As an alternative, the UV curing chamber also includes a cooling component configured to circulate cold air into the accommodating space after the adhesive has cured.

[0019] As an alternative, the aforementioned cooling component is a vortex tube.

[0020] As an optional solution, the UV curing chamber also includes a control component, which includes a controller and an operation panel connected in communication.

[0021] The glass sheet production line includes the aforementioned UV curing chamber.

[0022] The beneficial effects of this utility model are as follows:

[0023] This utility model provides a UV curing chamber. In use, the chamber door is opened, the adhesive is placed on the platform, the chamber door is closed, the pressure relief valve is closed, and the vacuum pump evacuates the gas in the containment space through the air pipe. When the gas pressure in the containment space reaches a certain low value, the vacuum pump stops working and maintains this state for a certain period of time. During this process, air bubbles are discharged from the adhesive under negative pressure. Then, the UV light source is turned on to cure the adhesive. After the pressure relief valve is released, the chamber door is opened and the cured adhesive is taken out from the platform. In other words, this UV curing chamber integrates defoaming and curing functions. After defoaming, curing proceeds immediately without the need to transfer the adhesive, improving production efficiency and avoiding secondary contamination of the adhesive during the transfer process.

[0024] This utility model also provides a glass sheet production line, including the aforementioned UV curing chamber. By adopting the aforementioned UV curing chamber, the glass sheet production line performs defoaming and curing operations through a single UV curing chamber, reducing operational complexity, saving on the number of devices, lowering costs, and improving product quality.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0037] This embodiment provides a UV curing chamber. Using this chamber, the defoaming and curing operations of the adhesive can be performed sequentially within a single space, eliminating the need for adhesive transfer, thus improving production efficiency and preventing secondary contamination of the product. Figures 1-3 As shown, the UV curing chamber includes a chamber body 10, a vacuum assembly 20, a stage 30, a UV light source 40, and a pressure relief valve 50. The chamber body 10 forms an internal accommodating space 11. The chamber body 10 is generally rectangular, and a door 12 is provided on the front side of the chamber body 10. The door 12 can open or close the accommodating space 11. The vacuum assembly 20 includes a vacuum pump 21 and an air pipe 22. The vacuum pump 21 is installed on the outside of the chamber body 10, and one end of the air pipe 22 is connected to the accommodating space 11, and the other end is connected to the vacuum pump 21. The stage 30 is disposed in the accommodating space 11 and is used to hold the adhesive to be cured. The UV light source 40 is provided at least on the upper side of the interior of the chamber body 10. The pressure relief valve 50 is installed in the chamber body 10 and is configured to close or allow the accommodating space 11 to communicate with the outside.

[0038] In use, the UV curing chamber is operated by opening the chamber door 12, placing the adhesive on the stage 30, closing the chamber door 12, closing the pressure relief valve 50, and using the vacuum pump 21 to evacuate the gas in the accommodating space 11 through the air pipe 22. When the air pressure in the accommodating space 11 reaches a certain low value, the vacuum pump 21 stops working and maintains this state for a certain period of time. During this process, air bubbles are discharged from the adhesive under negative pressure. Then, the UV light source 40 is turned on to cure the adhesive. After the pressure relief valve 50 is released, the chamber door 12 is opened and the cured adhesive is taken out from the stage 30. In other words, this UV curing chamber integrates defoaming and curing functions. After defoaming, curing proceeds immediately without the need to transfer the adhesive, improving production efficiency and avoiding secondary contamination of the adhesive during the transfer process.

[0039] Optionally, such as Figure 3 As shown, the UV curing chamber also includes heating tubes 60, with multiple heating tubes 60 arranged side-by-side on at least one side of the chamber body 10. With this configuration, the heating tubes 60 can simultaneously heat the adhesive during the defoaming process, increasing the fluidity of the adhesive and reducing the resistance to the removal of air bubbles, thus facilitating rapid defoaming.

[0040] Optionally, such as Figure 3 As shown, at least one side wall of the box 10 is formed by an inner layer 13 and an outer layer 14 spaced apart. A number of heating tubes 60 are disposed between the inner layer 13 and the outer layer 14. The sandwich structure can play a role in heat preservation. At the same time, it can prevent the local temperature of the heating tubes 60 from being too high, so that the heating effect is more uniform after passing through the inner layer 13.

[0041] In this embodiment, the left and rear sides of the housing 10 are sandwiched. In other embodiments, the sandwiched sides can be flexibly adjusted according to the installation of the housing 10 and the various parts.

[0042] Optionally, such as Figure 1 As shown, the vacuum assembly 20 also includes a pressure sensor 23. The pressure sensor 23 is installed in the housing 10 and configured to monitor the air pressure inside the containment space 11 and communicate with the vacuum pump 21. The vacuum pump 21 is configured to stop vacuuming when the air pressure inside the containment space 11 drops to a first preset value and maintain this position for a preset time. Through the above configuration, the pressure sensor 23 functions as a pressure gauge in actual use. On the one hand, the operator can clearly know the pressure value inside the containment space 11 from the outside; on the other hand, the vacuum pump 21 can stop vacuuming in a timely manner, saving energy and preventing excessive pressure inside the containment space 11 from causing excessive pressure on the outside of the housing 10, which could damage the housing 10.

[0043] Optionally, such as Figure 1As shown, the vacuum assembly 20 also includes an alarm element 24, which is installed in the housing 10 and communicates with the pressure sensor 23. The alarm element 24 is configured to issue an alarm signal when the value of the pressure sensor 23 is lower than a second preset value. Thus, if the vacuum pump 21 malfunctions and the air pressure in the accommodating space 11 does not drop to the first preset value, it will stop working. When the air pressure continues to drop, the alarm element 24 will sound an alarm to prevent the air pressure from becoming too low.

[0044] Optionally, the alarm element 24 may be a light alarm and / or an audible alarm, which is not limited here.

[0045] Optionally, such as Figure 2 ( Figure 2 As shown in the figure (with the right and front side walls of the housing 10 concealed), the UV light source 40 is positioned at the top of the accommodating space 11. A reflector (not shown) is provided above the UV light source 40, configured to reflect the upward-emitting light from the UV light source 40 downwards. This allows more of the UV light source 40 to irradiate the adhesive on the stage 30, accelerating the curing process.

[0046] Optionally, such as Figure 2 As shown, the UV light source 40 is positioned at the top of the accommodating space 11 and includes several sub-light sources 41 arranged in a matrix. It can be understood that this arrangement ensures that the UV light source 40 provides vertical illumination rather than point illumination, resulting in more uniform curing of the adhesive on the plane.

[0047] Optionally, such as Figure 1 As shown, the UV curing chamber also includes a cooling element 70, which is configured to circulate cold air into the accommodating space 11 after the adhesive has cured. The cooling element 70 can rapidly inject cold air into the cavity, thereby accelerating the cooling of the chamber 10 and allowing for rapid curing of the next round of products within the chamber 10. This also speeds up the defoaming rate within the chamber 10 and improves the efficiency of target material processing and production.

[0048] Optionally, the cooling element 70 is a vortex tube. Vortex tube refrigeration requires no electricity or refrigerant, has low cost, simple structure, and is easy to maintain.

[0049] Optionally, the UV curing chamber also includes a control component 80, which includes a controller and an operation panel 81 connected via communication. The operation panel 81 is used to input operating parameters, and the controller is connected via communication with the vacuum pump 21 and the UV light source 40. Thus, before defoaming and curing, the operator can input the required parameters on the operation panel 81 to achieve automated defoaming and curing operations.

[0050] The operation process of this UV curing chamber is described below:

[0051] 1. Open the box door 12, place the adhesive on the platform 30, close the box door 12, and ensure that the pressure relief valve 50 is closed;

[0052] 2. Input various parameters on the operation panel 81 (e.g., first preset value, preset time, second preset value, UV light source 40 on time, etc.);

[0053] 3. Close the chamber door 12, the vacuum pump 21 starts working, the pressure in the accommodating space 11 drops to the first preset value, the vacuum pump 21 stops working, and the pressure is maintained for a preset time (at this time, the defoaming work ends);

[0054] 4. UV light source 40 is turned on, and after a period of time, UV light source 40 is turned off;

[0055] 5. The pressure relief valve 50 is opened, and the vortex tube circulates cold air into the accommodating space 11;

[0056] 6. Open the box door 12 and take out the cured adhesive.

[0057] This embodiment also provides a glass sheet production line, including the aforementioned UV curing chamber. By adopting the aforementioned UV curing chamber, the glass sheet production line performs defoaming and curing operations through a single UV curing chamber, reducing operational complexity, saving on the number of devices, lowering costs, and improving product quality.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
