Description

Technical Field

[0001] The invention belongs to the technical field of door leaf processing, and in particular relates to a door leaf and door pattern glass packaging process for preventing fogging. Background Art

[0002] The design of early entrance doors was relatively simple, mainly focusing on functionality, and the appearance was mostly monotonous flat style. Although this type of door has basic anti-theft and protection functions, it lacks aesthetics and decorativeness, and it is difficult to meet people's needs for home personalization and aesthetic improvement. Therefore, the existing entrance doors use a combination of door decorations and glass to change the monotonous appearance of traditional entrance doors. Door decorations can be customized according to different design styles, such as Chinese-style flower, bird, fish and insect patterns, European-style curly grass patterns, geometric patterns, etc., which complement the transparent texture of the glass, making the entrance door a highlight of home decoration and improving the taste and grade of the entire home.

[0003] The door grille and glass structure on the entrance door are usually double-layered glass that holds the door grille structure in the middle, thereby preventing dust accumulation on the door grille with complex surface structure, reducing the difficulty of cleaning, and ensuring the sound insulation and heat insulation performance of the door leaf through the double-layered glass structure.

[0004] However, the existing door pattern and glass packaging process has poor sealing performance. As the temperature changes, external humid air can easily enter the double-layer glass structure, generating water mist on the glass. In severe cases, mold may even occur. Therefore, the present application provides a door leaf, door pattern and glass packaging process that prevents fogging, aiming to prevent external water vapor from entering the double-layer glass to form water mist.

[0052] In order to make the objectives, technical solutions and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in combination with specific embodiments of the present application and with reference to the accompanying drawings.

[0053] The present invention provides a door leaf and door pattern glass packaging process for preventing fogging, and the packaging process is used to package a door leaf and door pattern glass packaging structure for preventing fogging, such as Figure 1-2 As shown, the packaging structure includes:

[0054] Door leaf plate 1, door flower assembly 2 and glass plate 3;

[0055] The door leaf plate 1 is composed of a plurality of spliced ​​plates 102, and the middle part of the door leaf plate 1 is an inlay frame 101;

[0056] The packaging process comprises the following steps:

[0057] S1: welding a plurality of the splicing plates 102 to form the door leaf plate 1, and leaving an inlay frame 101 in the middle of the door leaf plate 1;

[0058] S2: welding and sealing the joint seams of the inner side walls of the inlay frame 101 to form a first welding layer 103;

[0059] S3: coating glass glue on the surface of the first welding layer 103, and forming a first sealing glue layer 104 after a preset time;

[0060] S4: Weld the door flower assembly 2 to the middle of the inlay frame 101;

[0061] S5: coating glass glue on the inner and outer edges of the door flower assembly 2 to form a second sealing glue layer 4. After the second sealing glue layer 4 becomes sticky, two glass plates 3 are respectively adhered to the two sides of the door flower assembly 2.

[0062] S6: After the glass plate 3 is adhered, glass glue is coated on the outer edge of the glass plate 3, and the packaging is completed after the glass glue is cured.

[0063] The double-layer glass structure of aluminum alloy door leaves usually adopts a vacuum process to avoid the generation of water mist in the glass interlayer. However, the entrance door with a door flower structure cannot be carried out using a vacuum process because the door flower assembly 2 is connected to the door leaf plate 1 by welding. Therefore, the packaging process provided in the present application forms a first welding layer 103 by welding and sealing the joints of the inner wall of the inlay frame 101, thereby enhancing the sealing and structural strength of the inlay frame 101. This can prevent external moisture, dust and other impurities from entering the interior of the door leaf through the joints when the temperature changes, causing water mist to be generated in the interlayer of the glass plate 3, while also improving the stability of the entire packaging structure.

[0064] In a specific implementation, the step S1 specifically includes:

[0065] S101: soaking the splicing board 102 in a degreasing agent, rinsing with clean water and drying after a preset time;

[0066] S102: grinding and polishing the welding position of the splicing plate 102;

[0067] S103: Spot-welding and fixing the plurality of splicing plates 102.

[0068] Through pretreatment steps such as degreasing and grinding, the probability of defects in the welding process is reduced, the impact of welding quality problems on the sealing performance of the packaging structure is reduced, and the packaging quality can be effectively improved.

[0069] In a specific embodiment, Figure 4 As shown, the step S2 specifically includes:

[0070] S201: welding and sealing the joints of the inner wall of the inlay frame 101 to form a first welding layer 103. The welding and sealing effectively fills the joints, preventing impurities such as water vapor and dust from entering the glass interlayer through the joint gap of the inlay frame 101, and providing a basic sealing guarantee for preventing the glass from fogging.

[0071] S202: grinding the first welding layer 103 to remove welding slag and burrs so that the surface roughness meets the specified requirements. The presence of welding slag and burrs will not only affect the appearance of the first welding layer, but more importantly, may reduce its sealing and corrosion resistance. The welding slag may form gaps or holes on the surface of the welding layer, which become channels for water vapor and impurities to enter; the burrs may scratch other components during subsequent installation or use, or even damage the sealant layer;

[0072] S203: The inner wall of the mosaic frame 101 is leveled so that the flatness of the inner wall of the mosaic frame 101 is within the specified range. This is very important for the subsequent installation of the door flower assembly 2 and the glass plate 3. The flat inner wall can ensure the fit of the door flower assembly 2 and the glass plate 3 during installation, and avoid problems such as uneven installation gap and uneven force on the glass caused by uneven inner wall. The uniform installation gap helps to ensure the uniform distribution of the glass glue, improve the sealing effect, and also improve the stability and aesthetics of the entire door leaf.

[0073] like Figure 4 As shown, the thickness of the glass glue in step S3 is 2-3 mm, and a notch for welding the door flower assembly 2 is reserved on the first sealing glue layer 104 .

[0074] Since the thickness of the door leaf splicing plate 102 is generally thin, there may be local burn-through during the welding process, and there may be a small amount of gaps. Therefore, by covering with glass glue, impurities such as external water vapor and dust are prevented from entering the interlayer of the glass plate 3, thereby better preventing the glass from fogging;

[0075] The reserved gap provides space for the welding operation of the door flower assembly 2, avoiding interference of the glass glue on the welding process. In addition, if there is no reserved gap, the glass glue may melt and decompose due to high temperature during welding, producing harmful gases, affecting the welding quality, and may even damage the applied glass glue layer and destroy the sealing effect.

[0076] like Figure 5 As shown, the step S4 specifically includes:

[0077] S401: welding the four corners of the door flower assembly 2 to the four corners of the inlay frame 101 to form a second welding layer 203;

[0078] S402: The four sides of the door flower assembly 2 are welded to the inlay frame 101 to form a second welding layer 203. The second welding layers 203 on the four sides of the door flower assembly 2 are arranged at equal intervals.

[0079] The four corners of the door flower assembly 2 are welded to the four corners of the inlay frame 101 to form a second welding layer 203. The four corners are the key parts of the structure that are subjected to stress. Through welding, the door flower assembly 2 and the inlay frame 101 can be tightly combined at these important nodes; the welding layers equidistantly arranged on the four sides of the door flower assembly 2 can evenly disperse the stress to avoid stress concentration in certain parts and cause structural damage. When the door leaf is subjected to external force, each welding point bears the load together, thereby improving the bearing capacity and anti-deformation ability of the door leaf and extending the service life of the door leaf; at the same time, the second welding layers 203 equidistantly arranged on the four sides of the door flower assembly can reduce the length of the overall welding, thereby avoiding the possibility of the splicing plate 102 being burned through.

[0080] like Figure 3 As shown, the door flower assembly 2 includes: an outer frame 201 and a decorative component 202. The decorative component 202 is arranged inside the outer frame 201 and is fixedly connected to the outer frame 201. The thickness of the outer frame 201 is greater than that of the decorative component 202. The decorative component 202 does not protrude from the front and rear side surfaces of the outer frame 201. The above arrangement facilitates the packaging of the glass plate 3 and avoids interference between the decorative component 202 and the glass plate 3.

[0081] In a specific implementation, the step S5 specifically includes:

[0082] S501: Control the relative humidity of the packaging environment to 40%-50%, and polish and clean the surfaces of the door flower assembly 2, the mosaic frame 101, and the second welding layer 203; by controlling the relative humidity of the packaging environment, the curing and sealing effect of the glass glue can be improved. If the humidity is too high, the glass glue may absorb too much water during the curing process, resulting in incomplete curing and reduced bonding strength. It may also cause bubbles and whitening, affecting the sealing performance. If the humidity is too low, the glass glue may dry too quickly, resulting in a hard shell on the surface, but the inside is not completely cured, which will also reduce the sealing effect. Appropriate humidity helps the glass glue to cure normally and ensure the stability of its sealing performance.

[0083] By controlling the humidity of the packaging environment, the air humidity inside the glass interlayer can be controlled to avoid the air humidity reserved inside the glass interlayer during the packaging process being too high, which may cause water mist inside the glass interlayer.

[0084] S502: seal one side edge of the door flower assembly 2, and then place the other side upward and horizontally; by sealing in a horizontal state, the uniformity of the sealing layer can be guaranteed, thereby ensuring the sealing effect and avoiding local weakness of the sealing layer.

[0085] S503: Apply glass glue to the edge of the door flower assembly 2 facing upward to form a second sealing layer 4. After the second sealing layer 4 becomes sticky, adhere the glass plate 3 to the second sealing layer 4 and clamp it with a clamp. In a specific embodiment, the clamp is evenly distributed on the edge of the glass plate 3 to provide a uniform and stable clamping force, thereby ensuring the sealing effect of the glass plate 3 and the door flower assembly 2, ensuring that the glass glue fully exerts its bonding effect during the curing process, and forming a firm connection between the two.

[0086] S504: Turn the sealed side of the door flower assembly 2 upward and place it horizontally, remove the sealing layer and repeat step S503.

[0087] In a specific embodiment, Figure 6 As shown, the step S6 specifically includes:

[0088] S601: After the glass plates 3 are adhered, the glass plates 3 on one side are placed horizontally, and the clamps on this side are removed, and then glass glue is applied to the outer edge of the glass plates 3 to form a third sealing glue layer 5;

[0089] S602: After the third sealing glue layer 5 on one side solidifies for a preset time, the glass plate 3 on the other side is turned upward and placed horizontally, the clamp on this side is removed, and then glass glue is applied to the outer edge of the glass plate 3 to form the third sealing glue layer 5; the glass plate 3 on one side is placed horizontally and the clamp is removed before the glue application operation, which can provide a stable operating platform for applying the third sealing glue layer 5 on the basis of ensuring that the glass plate 3 and the door flower assembly 2 are firmly bonded. At this time, removing the clamp will not affect the existing bonding effect, and it is convenient to fully and evenly apply glue to the outer edge of the glass plate;

[0090] S603: After the third sealing glue layer 5 on this side solidifies for a preset time, the packaging is completed.

[0091] After the glass plate 3 is adhered, glass glue is coated on its outer edge to form a third sealing layer 5, which further enhances the overall sealing effect of the glass interlayer. The previous sealing operation may have slight gaps or weak points. The third sealing layer can fill these potential loopholes to prevent external impurities such as moisture, dust, etc. from entering the interior of the door leaf, better protect the door flower assembly and the glass plate, and effectively avoid the occurrence of glass fogging.

[0092] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
