Glass panel bonding structure and extractor hood

Abstract

This utility model provides a glass panel bonding structure and a range hood. The glass panel bonding structure includes a sheet metal bracket, which includes a base body for bonding with the glass panel. The base body has several positioning protrusions spaced apart on the bonding surface of the glass panel, and several exhaust holes spaced apart. When the bonding surface is bonded to the adhesive layer applied to the surface of the glass panel, the positioning protrusions are embedded in the adhesive layer and abut against the glass panel, and the adhesive layer is partially embedded in the exhaust holes. This ensures that the adhesive layer between the bonding surface and the glass panel maintains a uniform thickness through the positioning effect of the positioning protrusions, and effectively exhausts air and increases the bonding and adhesion surface area through the exhaust holes. This improves the bonding strength and quality of the two in high-temperature environments, effectively solving the problem of the glass panel detaching from the sheet metal body of the range hood in high-temperature environments, and improving the product quality, service life, safety, and user experience of the range hood.

Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to a glass panel bonding structure and a range hood using the same. Background Technology

[0002] With the continuous development of kitchen appliance technology, mid-to-high-end range hoods have widely adopted touchscreen designs to enhance user experience and product aesthetics. However, in the working environment of a range hood, the heat generated during cooking is drawn into the air intake along with the heated fumes, causing the surface temperature of the device to rise. This places higher demands on the bonding structure between the touchscreen / glass panel assembly and the main body of the range hood (usually made of sheet metal).

[0003] In the high-temperature operating environment of range hoods, traditional adhesive structures suffer from insufficient heat resistance of adhesive materials, which accelerates aging. In addition, the thickness of the adhesive structure is often uneven in various places, resulting in poor adhesion / bonding between the touch screen / glass panel assembly and the sheet metal body. In some cases, the touch screen / glass panel assembly may even detach from the sheet metal body, affecting the product quality, service life, safety and user experience of the range hood. Utility Model Content

[0004] This utility model proposes a glass panel bonding structure and a range hood using the same structure, in order to solve the technical problem that the existing glass panel bonding structure of the range hood is prone to poor bonding between the glass panel component and the sheet metal body under high temperature environment due to aging of the bonding structure and uneven thickness, or even detachment from the sheet metal body.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides a glass panel bonding structure, including:

[0007] Sheet metal bracket, the sheet metal bracket includes a base body for bonding with a glass panel, the base body for bonding the glass panel has a number of positioning protrusions spaced apart, and the base body also has a number of vent holes spaced apart.

[0008] When the adhesive surface is bonded to the adhesive layer applied to the surface of the glass panel, the positioning protrusion is embedded in the adhesive layer and abuts against the glass panel, and part of the adhesive layer is embedded in the vent hole.

[0009] Preferably, the positioning protrusion is a boss that protrudes from the attachment surface.

[0010] Preferably, the boss is formed by bending the base body from the side of the base body away from the attachment surface to the attachment surface, and a groove is formed on the side of the base body away from the attachment surface that faces the boss.

[0011] Preferably, the boss is frustum-shaped.

[0012] Preferably, the junction between the periphery of the boss and the attachment surface forms a chamfered transition surface.

[0013] Preferably, the exhaust port is a circular through-hole.

[0014] Preferably, the adhesive layer is a silicone adhesive layer.

[0015] Furthermore, the base body is rectangular, and the sheet metal support also includes:

[0016] The bracket has a folded edge that surrounds the other side of the base body, opposite to the surface it is attached to.

[0017] Furthermore, the sheet metal bracket also includes:

[0018] A strip-shaped through groove is located in the middle of the base body;

[0019] A through-slot frame is set around the slot opening of the corresponding strip through-slot on the opposite side of the base body facing away from the attached surface.

[0020] This utility model also provides a range hood, including a main unit and the aforementioned glass panel bonding structure, and a sheet metal bracket for connecting to the main unit.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The glass panel bonding structure provided by this utility model has a base body of a sheet metal bracket with several positioning protrusions and vent holes spaced apart. When the attachment surface of the base body is bonded to the connecting adhesive layer (silicone adhesive layer) applied to the surface of the glass panel, the positioning protrusions are embedded in the connecting adhesive layer and abut against the glass panel, and the connecting adhesive layer is partially embedded in the vent holes. This allows the connecting adhesive layer (silicone adhesive layer) between the attachment surface of the sheet metal bracket and the glass panel to maintain a uniform thickness through the positioning effect of the positioning protrusions. At the same time, since the connecting adhesive layer does not need to be too thick to achieve a uniform thickness, and the vent holes can effectively vent air and increase the bonding and adhesion surface area, thereby improving the bonding strength and quality between the sheet metal bracket and the glass panel in high-temperature environments.

[0023] Meanwhile, the glass panel bonding structure provided by this utility model uses a silicone adhesive layer with good heat resistance and weather resistance, which further ensures that the glass panel remains stably and firmly installed on the sheet metal unit body of the range hood through the sheet metal bracket under long-term high temperature environment. This effectively solves the problem of the glass panel falling off the sheet metal unit body of the range hood under high temperature environment, and improves the product quality, service life, safety and user experience of the range hood.

[0024] In addition, the glass panel bonding structure provided by this utility model also takes into account the stability of the production process, making the bonding process simple and quick to operate, accurate and reliable in positioning, which is conducive to improving the quality stability and large-scale production of range hood products.

[0025] On the other hand, the glass panel bonding structure also improves the overall aesthetics and user experience of the range hood, enhancing its market competitiveness. Attached Figure Description

[0039] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer, the following description is provided in conjunction with the appendix. Figure 1-10 The present invention will be further described in detail with reference to the embodiments.

[0040] Please refer to the following: Figure 1-9 The glass panel bonding structure provided by this utility model includes:

[0041] The sheet metal bracket 1 includes a base body 11 for bonding with a glass panel 2 or a glass panel 2 assembly or a touch screen assembly. The base body 11 has a plurality of positioning protrusions 12 spaced apart on the bonding surface 111 of the glass panel 2. The base body 11 also has a plurality of vent holes 13 spaced apart, which penetrate the bonding surface 111 of the base body 11 and the other side of the base body 11 facing away from (relative to) the bonding surface 111.

[0042] When the adhesive surface 111 is bonded to the adhesive layer 3 applied to the surface of the glass panel 2, the positioning protrusion 12 is embedded in the adhesive layer 3 and abuts against the glass panel 2, and the adhesive layer 3 is partially embedded in the vent hole 13.

[0043] The sheet metal bracket 1 of the glass panel bonding structure provided by this utility model has a base body 11 with a plurality of positioning protrusions 12 and vent holes 13 spaced apart. When the attachment surface 111 of the base body 11 is bonded to the connecting adhesive layer 3 applied to the surface of the glass panel 2, the positioning protrusions 12 are embedded in the connecting adhesive layer 3 and abut against the glass panel 2, and the connecting adhesive layer 3 is partially embedded in the vent holes 13. This ensures that the connecting adhesive layer 3 filling the space between the attachment surface 111 of the sheet metal bracket 1 and the glass panel 2 maintains a uniform thickness through the positioning action of the positioning protrusions 12. To achieve uniform thickness, the adhesive layer 3 does not need to be too thick; a strong bond can be achieved even with a relatively thin adhesive layer 3. Furthermore, by using the air vents 13, the adhesive layer 3 can be effectively vented, and the surface area for bonding and adhesion between the sheet metal bracket 111 and the adhesive layer 3 can be increased. This improves the bonding strength and quality between the sheet metal bracket 1 and the glass panel 2 under high-temperature conditions. In addition, the thickness of the adhesive layer 3 can be kept uniform throughout, minimizing the aging effect of the adhesive material on the adhesive layer 3 under high-temperature conditions and ensuring a strong bond.

[0044] In this embodiment, the adhesive layer 3 is a silicone adhesive layer.

[0045] As a preferred embodiment of this example, the adhesive layer 3 is a two-component silicone adhesive layer with high heat resistance, high adhesive strength and good weather resistance.

[0046] The glass panel bonding structure provided by this utility model uses a silicone adhesive layer 3 with good heat resistance and weather resistance. With the functional cooperation of the positioning protrusion 12 and the exhaust hole 13, it further ensures that the glass panel 2 remains stable and firmly installed on the sheet metal unit body of the range hood through the sheet metal bracket 1 under long-term high temperature environment. This effectively solves the problem of the glass panel 2 falling off the sheet metal unit body of the range hood under high temperature environment, and improves the product quality, service life, safety and user experience of the range hood.

[0047] Furthermore, the glass panel bonding structure provided by this utility model also takes into account the stability of the production process. The structure layout of the glass panel bonding structure is simple and easy to process. While reducing the production cost of the glass panel bonding structure, it makes the bonding process between the sheet metal bracket 1 and the glass panel 2 simple, quick and accurate, and reliable. This is conducive to improving the quality stability of the range hood product, reducing costs and increasing efficiency, and promoting its large-scale production.

[0048] On the other hand, the glass panel bonding structure provided by this utility model has a simple appearance, which also improves the overall aesthetics of the range hood and the user experience, thereby enhancing the market competitiveness of the range hood.

[0049] Please refer to the following: Figure 1-4In this embodiment, the positioning protrusion 12 is a boss that protrudes from the attachment surface 111.

[0050] Please refer to the following: Figure 1-4 8-9, as a preferred embodiment of this embodiment, the boss (positioning protrusion 12) is formed by bending the base body 11 from the other side of the base body 11 away from the attachment surface 111 to the attachment surface 111, and a groove 14 is formed on the other side of the base body 11 away from the attachment surface 111, facing the boss.

[0051] Please refer to the following: Figure 1-4 8-9, as a preferred embodiment of this example, the boss (positioning protrusion 12) is in the shape of a frustum.

[0052] Please refer to the following: Figure 1-4 8-9. As a preferred embodiment of this example, the periphery of the boss (positioning protrusion 12) and the attachment surface 111 form a chamfered transition surface 121.

[0053] Please refer to the following: Figure 1-4 In the preferred embodiment of this example, the exhaust hole 13 is a circular through hole.

[0054] In other embodiments, the exhaust port 13 may also be a rectangular port or a port of other shapes.

[0055] Please refer to the following: Figure 1-9 In this embodiment, the base body 11 is rectangular, and the sheet metal bracket 1 further includes:

[0056] The bracket folded edge 15 is arranged around the periphery of the other side of the base body 11 facing away from the attachment surface 111.

[0057] Please refer to the following: Figure 1-2 In a preferred embodiment of this invention, the end of the bracket folded edge 15 away from the base body 11 is provided with a number of screw mounting holes at intervals for connecting to a fixed object such as the main body of a range hood.

[0058] Please refer to the following: Figure 1-2 In this embodiment, the sheet metal bracket 1 further includes:

[0059] A strip-shaped through groove 16 is located in the middle of the base body 11; a through groove frame 17 is arranged around the groove opening of the strip-shaped through groove 16 on the other side of the base body 11 opposite to the attachment surface 111.

[0060] This utility model also provides a range hood, including a main unit (not shown in the figure), and the aforementioned glass panel bonding structure, with a sheet metal bracket 1 for connecting to the main unit.

[0061] Please refer to the following: Figure 5-8In this embodiment, the glass panel bonding structure further includes:

[0062] Sheet metal edge strip 4, adhesive layer 3 bonded to the surface of glass panel 2, and spaced apart from sheet metal bracket 1.

[0063] In a preferred embodiment of this invention, the sheet metal edge strip 4 is provided with a plurality of vent holes 13 at intervals.

[0064] Please refer to the following: Figure 5-6 In this embodiment, the sheet metal bracket 1 is made of stamped sheet metal parts and / or powder-coated sheet metal parts. Before bonding the base body 11 and the glass panel 2 of the sheet metal bracket 1, plasma cleaning equipment is required to perform plasma dust removal and cleaning pretreatment on the surface (attachment surface 111) of the stamped sheet metal parts and powder-coated sheet metal parts of the base body 11 to remove oil and impurities from the attachment surface 111 of the sheet metal parts. At the same time, the attachment surface 111 of the sheet metal parts is roughened to increase the contact surface area of ​​the adhesive material of the connecting adhesive layer 3.

[0065] In addition, it is necessary to draw a glue positioning frame line 21 on the glue application area (glue application surface) of the glass panel 2 to ensure accurate dust removal and glue application in the subsequent process. Before bonding the sheet metal bracket 1, the area of ​​the glass panel 2 where the sheet metal bracket 1 will be bonded (the area of ​​the glue positioning frame line 21) should be pre-treated with plasma cleaning equipment to remove dust and further enhance the bonding strength between the glass panel 2, the adhesive material of the connecting adhesive layer 3 and the sheet metal bracket 1.

[0066] In a preferred embodiment of this invention, the plasma cleaning device is an ion dust removal gun.

[0067] In this embodiment, a mechanical positioning and pressing device (not shown in the figure) is used to achieve precise pressing and positioning between the sheet metal bracket 1 and the connecting adhesive layer 3 applied to the surface of the glass panel 2. The pre-treated sheet metal bracket 1 and the glass panel 2 with the connecting adhesive layer 3 formed after applying adhesive are pressed together quickly, ensuring that the thickness of the connecting adhesive layer 3 in the glass panel assembly formed by the pressed sheet metal bracket 1 and the glass panel 2 is uniform, improving the pressing quality stability of the glass panel bonding structure, and increasing the production efficiency of the range hood.

[0068] In a preferred embodiment of this invention, the mechanical positioning and pressing device is a pressing fixture.

[0069] As a preferred embodiment of this invention, the pressing fixture consists of an upper mold driven by a press and a lower mold that cooperates with the upper mold.

[0070] In this embodiment, the connecting adhesive layer 3 is a two-component silicone adhesive layer. The glass panel assembly formed by the pressed sheet metal bracket 1 and the glass panel 2 can be cured at room temperature without the need for ultraviolet irradiation and high-temperature baking, which effectively reduces the production cost of the range hood.

[0071] In this embodiment, the curing process of the glass panel assembly formed by the sheet metal bracket 1 and the glass panel 2 after pressing is as follows:

[0072] (1) Glue application requirements: Use a glue gun to apply silicone glue evenly into the glue guide groove of the sheet metal bracket 1 or along the glue application positioning frame line 21 of the glass panel 2, so that the glue outlet diameter is uniform and the glue outlet moving speed is kept consistent with the glue application speed during the glue application process to avoid glue overflow.

[0073] (2) Precautions: After changing the adhesive, pull the trigger to discharge the adhesive first. Install the nozzle only after the A and B components are discharged simultaneously. When the nozzle is dispensing adhesive for the first time, in order to ensure that the two adhesives are mixed evenly, discharge a length of adhesive ≥600mm (do not use). It can only be used when the discharged adhesive is completely black. Starting from the start of dispensing, after the adhesive is applied to the sheet metal bracket 1 and glass panel 2, it must be placed on the fixture for pressing within 5 minutes. If the time limit is exceeded, be sure to clean the adhesive on the glass panel 2 and inspect it before dispensing again. If the pressing fixture malfunctions, the dispensing station must stop dispensing adhesive immediately, and the adhesive on the sheet metal bracket 1 and glass panel 2 that have been dispensed must be removed. Dispensing should be done continuously. If the glue gun stops dispensing adhesive for more than 120 seconds, discharge 400-600mm of adhesive to prevent solidification.

[0074] (3) Self-inspection: Check whether the silicone sealant layer is evenly applied and whether the dispensing diameter is qualified. Check whether the sealant is absolutely black and whether the diameter of the sealant strip meets the requirements. When using 1 / 3 or 2 / 3 tubes of sealant, check whether there are any abnormalities such as internal leakage or damage in the tube. Perform a butterfly test on each tube of sealant to check the mixing uniformity: Apply about 10g of sealant to white paper, then fold and flatten the white paper and pull it apart. If the color is uneven or there are white streaks, it is unqualified and the tube needs to be replaced. Keep a sample of each tube of sealant and mark the time for testing the curing status of the sealant.

[0075] (4) Mutual inspection: Whether the adhesive sheet metal bracket 1 and glass panel 2 have undergone full dyne value inspection;

[0076] (5) Quality inspection: After bonding is completed, strict quality inspection is carried out, including bonding strength test, heat resistance test and environmental performance test, to ensure that the glass panel component products meet all standards.

[0077] (6) Production process optimization: The bonding process is incorporated into the overall production process of the range hood. By optimizing the production line layout and process flow, production efficiency and the consistency of glass panel components are improved, and continuous improvement is achieved.

[0078] In this embodiment, the bonding, pressing, and placement requirements between the sheet metal bracket 1 and the glass panel 2 are as follows:

[0079] (1) Material requirements: Use pressing tool to press the sheet metal bracket 1 of the range hood and the glass panel 2. When taking out the pressed glass panel assembly, you can only touch the position outside the glue positioning frame line 21 of the glass panel 2, and you must not touch the position inside the glue positioning frame line 21 to avoid contaminating the bonding contact surface.

[0080] (2) Self-inspection: Check whether the sheet metal bracket 1 and the glued positioning frame line 21 are misaligned and whether they are pressed in place. Check whether the glass panel 2 is damaged or has excess glue. Use a feeler gauge to check all gaps. Use tooling to check the position and dimensions after glue application. After assembling the sheet metal bracket 1 and applying glue, conduct a first inspection of 5 consecutive production units and assemble the corresponding glass panel components to ensure there is no misalignment before mass production.

[0081] In this embodiment, before the sheet metal bracket 1 and the glass panel 2 are bonded and pressed together, the pressing fixture needs to be tested with pressure-sensitive paper and a paper removal test:

[0082] Cut the pressure-sensitive paper into small rectangles of appropriate size. Place it above the sheet metal bracket 1 and glass panel 2 before pressing them together. If the pressure-sensitive paper is discontinuous, does not change color, or only slightly red, it is considered unqualified. If it changes color continuously to a deep red, it is considered qualified. Place the paper strips steadily on top of the product to be pressed. Place the paper strips at both ends and in the middle of the product to be pressed. After the upper mold presses down, pull the paper strips outward along the direction of the paper strips during the pressure holding process. If the paper strips cannot be pulled out or break, it is considered that the press, upper mold, and lower mold are all qualified.

[0083] In this embodiment, the tooling requirements for the glass panel assembly formed by the sheet metal bracket 1 and the glass panel 2 after curing are as follows:

[0084] Place the finished glass panel components that have been left to stand still onto the tooling cart, separating each layer with pearl cotton. The tooling cart must be covered with cling film to prevent dust and have material labels affixed. Self-inspection: Check if the pearl cotton is properly protecting the components and if the material labels are complete. Mutual inspection: Check if the components have been left to stand for 2 hours and if the appearance is good.

[0085] In this embodiment, the placement requirements for the finished glass panel assembly formed by the sheet metal bracket 1 and the glass panel 2 are as follows:

[0086] After standing for 2 hours, the material can be loaded onto the vehicle. Each layer should be separated by pearl cotton and protected from dust with cling film. Affix material labels including model, name, code, and date. If the ambient temperature is below 15℃, the material must be placed in the glue-applying room for 12 hours after loading (temperature: 15-35℃, relative humidity: 45-75%) before being moved to other areas. Glass panels requiring testing must be placed in the glue-applying room for 24 hours for a tensile test, with a required tensile strength ≥500N. Only after passing the test can the material be used online.

[0087] Please see Figure 10 In this embodiment, the production process of the glass panel assembly of the range hood using the glass panel bonding structure provided in this embodiment includes (wherein the parts refer to sheet metal bracket 1 and glass panel 2):

[0088] The process involves several steps: cleaning the parts to be glued; plasma cleaning the glued areas; full inspection of the dyne values ​​at the glued areas; applying adhesive to the glued areas; positioning and pressing the tooling; placing the pressed components in a static position; full inspection of the bracket positions; full inspection of the bracket gaps; retaining samples of every 50 pieces for tensile testing; loading the tooling cart and placing it in a static position for at least 24 hours; and finally putting it into use. These steps ensure that the bonding quality of the range hood's glass panel components is under control.

[0089] In summary, the glass panel bonding structure provided by this utility model effectively realizes the closed-loop production process of the sheet metal bracket 1 and the glass panel 2 assembly: pretreatment of the sheet metal bracket 1 and the glass panel 2, glue application and pressing, static placement and curing, and closed-loop management of inspection at each stage, effectively ensuring the stable quality and efficient production of the glass panel 2 assembly of the range hood.

[0090] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Those skilled in the art should understand that any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
