Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, and in particular to a glass tin plating device. Background Technology

[0002] Glass is an amorphous inorganic solid material, typically composed primarily of silicon dioxide (SiO2), with the addition of alkali metal oxides (such as Na2O and K2O), alkaline earth metal oxides (such as CaO and MgO), and other additives (such as alumina and boron oxide). This mixture is formed by melting at high temperatures and then rapidly cooling. Due to the extremely rapid cooling, atoms or molecules cannot arrange themselves regularly, resulting in a disordered amorphous structure. This structure endows glass with unique physical and chemical properties, making it widely used in construction, daily necessities, optics, electronics, medicine, new energy, and art.

[0003] Due to factors such as surface composition, ambient temperature and humidity, and storage time, flat glass surfaces are prone to mold growth. When mold reaches a certain level, the glass must be discarded, resulting in economic losses. To reduce the likelihood of mold growth on glass surfaces, the following methods are commonly used: 1) placing spacer paper between stacked glass pieces for physical mold prevention; 2) applying reagents or powders to the glass surface for chemical mold prevention. However, the above two methods are not very effective at preventing mold growth and cannot improve the adaptability of flat glass products to humid environments. Even after prolonged storage, there remains a high probability of mold growth.

[0004] Therefore, there is an urgent need to develop a glass tin plating device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a glass tin plating device that can form a tin protective layer on the glass surface to effectively isolate moisture and air from direct contact with the glass surface, thereby reducing the possibility of mold growth on the glass surface.

[0024] As a preferred embodiment of the glass tin plating device provided by this utility model, the glass tin plating device further includes a pressure equalization block, which is disposed between the base and the upper cover and located above the transmission component. The pressure equalization block is provided with a plurality of air passage holes arranged in an array.

[0025] As a preferred embodiment of the glass tin plating device provided by this utility model, the base is made of heat-insulating material.

[0026] The beneficial effects of this utility model are as follows:

[0027] The glass tinning apparatus provided by this utility model has a heating component that heats and evaporates the tin plate it carries, creating a tin-rich space between the upper cover and the base.

[0041] Before explaining any embodiment of the present invention in detail, it should be understood that the present invention is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0042] In this invention, the terms "comprising," "including," "having," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0043] In this invention, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following related objects have an "and / or" relationship.

[0044] In this invention, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0045] In this invention, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0046] In this invention, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can be performed by one part, one component, or a combination of multiple parts.

[0047] In this utility model, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this utility model. Furthermore, in the context, it should be understood that when one element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent the direct orientation but can also be understood as the lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0048] Figure 1 A schematic diagram of the glass tin plating apparatus provided in this embodiment is shown. Figure 2 An exploded structural diagram of the glass tin plating apparatus provided in this embodiment is shown. Figure 3 One of the cross-sectional views of the glass tin-plating apparatus provided in this embodiment is shown. Figures 1-3As shown, this embodiment provides a glass tin plating apparatus, which includes a base 10, a supporting heating component 20, a top cover 30, and a transmission component 40. The base 10 has a receiving chamber 101; the top cover 30 is disposed above the base 10; the supporting heating component 20 is located in the receiving chamber 101, and the supporting heating component 20 is used to support a tin plate 200 and can heat the tin plate 200 to make it volatilize and form tin molecules, thereby forming a tin-rich space between the top cover 30 and the base 10; the transmission component 40 is configured to transmit the glass plate 100 to be tin-plated into the tin-rich space, thereby forming a tin protective layer on the surface of the glass plate 100 to be tin-plated.

[0049] The glass tinning apparatus provided in this embodiment heats the tin plate 200 supported by the heating component 20, causing it to evaporate and forming a tin-rich space between the upper cover 30 and the base 10. When the transmission component 40 transmits the glass plate 100 to be tinned into the tin-rich space, a tin protective layer is formed on the surface of the glass plate 100 in the tin-rich environment. This effectively isolates moisture and air from direct contact with the surface of the glass plate 100, thereby reducing the possibility of mold growth on the surface of the glass plate 100. This glass tinning apparatus has a simple structure, is easy to operate, and can form a stable tin protective layer on the surface of the glass plate 100, thereby reducing economic losses caused by mold growth and scrapping of the glass plate 100.

[0050] It should be explained that in practical use, the glass tin plating device can be set at the end of the glass production line or at the beginning of the glass cutting production line. This allows the existing production line to be equipped with the glass tin plating device without making significant investment in innovation, thereby effectively reducing the probability of mold growth on finished glass, reducing the scrap rate after mold growth, reducing economic losses, and improving product quality.

[0051] Optionally, the top of the upper cover 30 is provided with an air extraction port 301, which is used to connect to an air extraction assembly (not shown in the figure). By providing an air extraction port 301 on the upper cover 30 that can be connected to the air extraction assembly, a negative pressure can be formed between the base 10 and the upper cover 30 when the air extraction assembly is working. This causes the tin molecules formed after the tin plate 200 is heated and evaporated to flow towards the air extraction port 301, so that most of the tin molecules can pass through the lower surface of the glass plate 100 to be tinned and adhere to it, forming a tin protective layer.

[0052] Understandably, due to the flow of tin molecules, most tin molecules will adhere to the lower surface of the glass plate 100 to be tinned, while it is difficult to form a tin protective layer on the upper surface. Therefore, in actual operation, after the first side of the glass plate 100 is coated with a tin protective layer, the operator can flip the glass plate 100 and place it back on the transfer assembly 40 to form a tin protective layer on the second side. Furthermore, if a glass plate produced by the float glass process has a tin-plated side, the untin-plated side of the float glass plate can be placed face down on the transfer assembly 40 to form a tin protective layer on the untin-plated side.

[0053] Figure 4 A second cross-sectional view of the glass tin-plating apparatus provided in this embodiment is shown. Figure 4 and combined Figure 2 , Figure 3 As shown, in this embodiment, the supporting heating assembly 20 includes a supporting block 21 and a heating element 22. The supporting block 21 is disposed in the receiving chamber 101 and is used to support the solder plate 200. The heating element 22 is disposed in the receiving chamber 101 and is located below the supporting block 21. The heating element 22 heats the solder plate 200 through the supporting block 21. In this example, the heating element 22 can be directly an electric heater, which has a fast heating speed, high control precision, and no pollution.

[0054] Of course, in other embodiments, the supporting heating assembly 20 includes a supporting block 21 and a heating wire (not shown in the figure). The supporting block 21 is disposed in the accommodating chamber 101 and is used to support the solder plate 200. The heating wire is embedded in the supporting block 21 so as to heat the solder plate 200 through the supporting block 21. This arrangement can also achieve the above-mentioned effect.

[0055] like Figure 2 As shown, the support block 21 is provided with a support groove 211 for supporting the tin plate 200. By providing the support groove 211, the tin plate 200 can be positioned and stably supported, preventing it from shifting relative to the support block 21 during operation and affecting the tin plating effect of the glass plate 100 to be tinned. In this embodiment, the support block 21 can directly adopt the tin bath from the float glass production process to simplify the processing technology and reduce processing costs.

[0056] Figure 5 A structural schematic diagram of the base 10 provided in this embodiment is shown. Figure 5 and combined Figure 4As shown, the receiving chamber 101 is a stepped groove, with the smaller groove facing downwards. The heating element 22 is located in the smaller groove of the receiving chamber 101, and the support block 21 is located in the larger groove of the receiving chamber 101 and rests on the stepped surface of the receiving chamber 101. This arrangement allows for precise positioning of the support block 21 and the heating element 22 on the base 10. It also prevents the support block 21 from directly pressing on the heating element 22, thus avoiding excessive pressure and damage to the heating element 22. Furthermore, it creates a gap between the support block 21 and the heating element 22 to facilitate heat dissipation.

[0057] Optionally, a wire hole 102 is provided on the side wall of the base 10, through which the electrical connection wire of the heating element 22 passes and is electrically connected to an external power source.

[0058] Optionally, a detection hole 103 is also provided on the side wall of the base 10. The detection end of the temperature detection element can extend into the accommodating chamber 101 through the detection hole 103 to detect the temperature inside in real time, thereby ensuring that the temperature inside the accommodating chamber 101 is within a preset temperature range, so that the tin plate 200 can volatilize, and preventing the temperature from becoming too high and exceeding the softening point temperature of the glass plate 100 to be tinned, which would affect the performance of the glass plate 100 to be tinned. It is understood that the maximum heating temperature of the heating element 22 should be lower than the softening point temperature of the glass plate 100 to be tinned, and the minimum heating temperature of the heating element 22 should be higher than the boiling point of the tin plate 200, so as to ensure that the tin plate 200 can volatilize.

[0059] Optionally, the base 10 is made of heat-insulating material to keep the high-temperature environment in the accommodating chamber 101 warm and prevent excessive heat loss that could lead to energy waste. In this embodiment, the base 10 can be made of heat-insulating bricks, which are readily available and can reduce processing costs.

[0060] In other embodiments, an insulation layer may be provided on the cavity wall of the accommodating chamber 101; or an insulation layer may be provided on the outer periphery of the base 10. This design can also achieve the above-mentioned effect.

[0061] like Figures 2-4 As shown, the glass tinning apparatus also includes a pressure equalizing block 50, which is disposed between the base 10 and the upper cover 30, and above the transmission assembly 40. The pressure equalizing block 50 has vent holes 501. The pressure equalizing block 50 provides uniform pressure to the glass plate 100 to be tinned on the transmission assembly 40, preventing positional displacement of the glass plate 100 under negative pressure. Optionally, multiple vent holes 501 are arranged in an array on the pressure equalizing block 50. This arrangement creates a uniform airflow between the base 10 and the upper cover 30, ensuring a uniform tin protective layer is formed on the glass plate 100.

[0062] Continue as Figure 2 As shown, the transmission assembly 40 includes a transmission frame 41, transmission shafts 42, and a drive unit (not shown in the figure). The transmission frame 41 is disposed on both sides of the base 10; multiple transmission shafts 42 are arranged at intervals along the length of the transmission frame 41, and both ends of each transmission shaft 42 are rotatably mounted on the transmission frame 41; the drive unit is configured to drive all the transmission shafts 42 to rotate. In other words, the transmission assembly 40 is a transmission roller device in the prior art, with a simple structure and stable transmission.

[0063] In some embodiments, the distance between two adjacent drive shafts 42 located directly above the heating assembly 20 is D1, and the distance between two adjacent drive shafts 42 at other locations is D2, wherein D1 is greater than D2. This arrangement reduces the obstruction of the drive shafts 42 to the tin-coated glass plate 100, maximizing the area exposed to the tin-rich space.

[0064] In some other embodiments, the transmission assembly 40 further includes anti-wear sleeves. Each transmission shaft 42 is fitted with an anti-wear sleeve, and two anti-wear sleeves are provided on the transmission shaft 42 located directly above the carrying heating assembly 20. The two anti-wear sleeves are respectively fitted onto the two ends of the corresponding transmission shaft 42. With this arrangement, the two anti-wear sleeves on the transmission shaft 42 located directly above the carrying heating assembly 20 can support the glass plate 100 to be tinned located above it. That is, when the glass plate 100 to be tinned is transmitted to the transmission shaft 42 located directly above the carrying heating assembly 20, most of the lower surface of the glass plate 100 to be tinned is spaced apart from the transmission shaft 42, thereby further increasing the area of ​​the lower surface of the glass plate 100 to be tinned exposed in the tin-rich space and improving the tinning effect.

[0065] It should be noted that, in actual operation, when the glass plate 100 to be tinned is conveyed to the drive shaft 42 located directly above the heating assembly 20, the drive unit can be controlled to stop working to extend the residence time of the glass plate 100 in the tin-rich space and improve the tinning effect. Of course, in other embodiments, when the glass plate 100 to be tinned is conveyed to the drive shaft 42 located directly above the heating assembly 20, the drive unit can be controlled to alternately rotate forward and reverse, achieving the same effect.

[0066] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments do not limit this utility model in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
