Technical Field

The present invention relates to the technical field of glass tempering processing, and in particular to a laminated temperature control method and system for tempered laminated glass.

Background Art

At present, tempered laminated glass, through the combination of tempering and laminating technology, has a new type of glass product with higher safety performance, earthquake resistance and sound insulation performance than traditional ordinary glass. It is widely used in the fields of construction and automobile. However, the product yield of tempered laminated glass is often affected by the laminating temperature. Therefore, it is necessary to further optimize the control accuracy of the laminating temperature of tempered laminated glass during the mass production process.

The existing method for controlling the lamination temperature of tempered laminated glass is usually to set the temperature of a heating furnace, add film between the glass sheets when the heating furnace reaches a preset temperature, heat to a preset heating temperature to melt the film, and then roll or vacuum the glass sheets to make them adhere together to form a laminate, and transport the laminated glass to a lower temperature area for cooling and edge sealing, thereby obtaining tempered laminated glass. However, differences in glass thickness or glass material will result in different adhesion effects between the glass and the film, and differences in cooling speed and cooling temperature of the glass laminate will also result in bubbles or deformation between the glass films, affecting the finished product yield of the tempered laminated glass. Therefore, it is necessary to further optimize the lamination temperature control of the tempered laminated glass.

DETAILED DESCRIPTION

The present application is further described in detail below in conjunction with the accompanying drawings.

In one embodiment, as shown in FIG1 , the present application discloses a method for controlling the lamination temperature of tempered laminated glass, which specifically includes the following steps:

S10: Obtaining the thickness of the single-sided glass and the material of the single-sided glass of the tempered laminated glass, and analyzing the laminate heating time for the tempered laminated glass to reach a semi-plastic state according to the thickness of the single-sided glass and the material of the single-sided glass.

Specifically, before laminating, the glass thickness of two or more tempered glasses to be laminated is scanned to obtain the thickness of the single-sided glass, and the material of each glass is obtained by manually inputting the corresponding glass material keyword, thereby obtaining the single-sided glass material. Different glass materials have different heat absorption properties. The corresponding heating temperature and heating time are set by querying the corresponding glass material to obtain relevant heat absorption performance parameters, and the lamination heating time for the tempered laminated glass to reach a semi-plastic state is calculated by formula (2). Formula (2) is as follows:

Wherein, t_热represents the heating time of the laminate in the semi-plastic state, δ represents the maximum thermal conductivity of the single-sided glass of the tempered laminated glass, H_均represents the comprehensive glass thickness of the tempered laminated glass, ΔC＝T_塑-T_现, wherein ΔC represents the difference between the current glass temperature and the glass temperature reaching the semi-plastic state, T_塑represents the temperature when the laminated surface of the glass reaches the semi-plastic state, T_现represents the actual temperature of the single-sided laminated glass, and V_温度represents the heat absorption rate of the glass.

S20: Obtaining the glass melting state and the corresponding heating temperature of the laminated glass bonding surface, analyzing the correlation between the glass melting state and the lamination heating time and heating temperature, and constructing a glass preheating relationship for the tempered laminated glass to reach the laminated state according to the analysis results.

Specifically, the glass melting state is analyzed by scanning the thermal imaging of the laminated glass bonding surface through thermal sensors according to the glass placement position. When the thermal imaging shows that the glass bonding surface is maintained in a preset heat range and is evenly distributed, the heating temperature, heating time and corresponding glass change state of the laminated glass in the process of reaching the melting state are data-correlated until the glass reaches a molten state, thereby obtaining the glass preheating relationship for the tempered laminated glass to reach the laminated state. The preheating process of heating the glass bonding surface to the molten state is intuitively represented through the glass preheating relationship, and the molten state of the glass on the glass bonding surface is preheated to meet the lamination requirements.

S30: Analyze the optimal laminating temperature of the current laminated glass according to the glass preheating relationship, and adjust the optimal temperature holding time in combination with the fusion state of the laminated glass at the optimal laminating temperature.

Specifically, as shown in FIG. 2 , step S30 specifically includes:

S301: According to the glass preheating relationship and the glass melting state change of the laminated glass bonding surface, the glass laminating temperature corresponding to when the laminated glass bonding surface reaches a preset laminating state is analyzed to obtain the optimal laminating temperature of the current laminated glass.

Specifically, according to the glass preheating relationship and the change of the glass molten state of the laminated glass bonding surface, the glass laminating temperature corresponding to when the laminated glass bonding surface reaches the preset laminating state is analyzed. If the preset laminating state is that the glass on the glass bonding surface is in a semi-plastic state, and the heat of the glass on the entire bonding surface is evenly distributed, then according to the glass preheating relationship, the laminated glass bonding surface is heated, and the glass laminating temperature when the laminated glass bonding surface reaches the preset laminating state is taken as the optimal laminating temperature. According to the glass preheating relationship and the change of the glass molten state, the optimal laminating temperature is maintained within the allowable range of the highest preheating temperature of the glass molten state.

S302: When the optimum lamination temperature is reached, a preset film is added between the laminating surfaces of the laminated glass to perform lamination work, and it is determined whether the laminating surfaces of the adjacent laminated glass and the laminating film are fully integrated.

Specifically, at the optimal laminating temperature, a pre-cut film is added between adjacent laminated glass bonding surfaces, and the film is heated while maintaining the optimal laminating temperature until the film melts, and the laminated glass bonding surfaces are bonded together to perform the laminating work. During the laminating work, whether the adjacent laminated glass bonding surfaces and the laminating are fully fused is determined based on whether there are bubbles or gaps between the film and the laminated glass bonding surfaces.

S303: If yes, the current optimal lamination temperature is maintained, and the tempered laminated glass in a fully fused state is subjected to a rolling process.

If yes, it means that there are no bubbles or gaps between the adjacent laminated glass bonding surfaces and the interlayer, and a fully fused state is achieved. In this case, the current optimal laminated temperature is maintained, and the transmission roller is controlled to perform rolling processing on the tempered laminated glass in a fully fused state at the current optimal laminated temperature. For example, the transmission roller is controlled to perform rolling extrusion on the opposite side of the laminated glass bonding surface, so that the excess interlayer in the laminated glass bonding surface is squeezed out from the edge of the glass.

S304: If not, adjust the current laminating temperature, and simultaneously perform roller pressing on the tempered laminated glass, and perform single-point heating on the tempered laminated glass that is not fully fused according to the rolling result.

Specifically, if no, it means that there are bubbles or gaps between the adjacent laminated glass bonding surfaces and the interlayer, and the state of full fusion has not been achieved. In this case, the current interlayer temperature is increased to further increase the preheating and melting of the glass and the interlayer, and the transmission roller is synchronously controlled to perform rolling processing on the tempered laminated glass. During the rolling process, the position of the glass bonding surface where the bubbles or gaps are located after each rolling is detected, and the corresponding tempered laminated glass that is not fully fused is subjected to single-point heating processing until the bubbles disappear during multiple rolling processes to achieve full fusion between the laminated glass bonding surface and the interlayer.

It should be noted that the purpose of eliminating bubbles or gaps can also be achieved by single-point glue injection at the position that is not fully fused and targeted glue filling at the gap position.

S40: calculating the glass tensile stress under the optimal temperature holding time, adjusting the rolling parameters of the tempered laminated glass according to the glass tensile stress, and obtaining the lamination control data of the tempered laminated glass.

Specifically, as shown in FIG3 , step S40 specifically includes:

S401: Obtaining the surface area of the single-sided glass, and performing finite element division processing on the bonded tempered laminated glass according to the surface area and thickness of the single-sided glass to obtain a plurality of finite element laminated glasses with uniform tensile stress distribution.

Specifically, the surface area of the single-sided glass is obtained by scanning, or all the tempered glasses involved in the glass lamination work are pre-cut to produce single-sided glass of preset specifications and sizes, so as to obtain the surface area of the single-sided glass. When the glass thickness is evenly distributed, the tempered glass is evenly divided into finite elements according to the surface area of the single-sided glass, and the tempered laminated glass after bonding is divided into multiple finite elements. When the glass thickness is unevenly distributed, the tempered laminated glass after bonding is divided into finite elements according to the difference in glass thickness and the surface area of the single-sided glass, such as being divided into multiple finite element laminated glasses with equal thickness or equal area.

S402: Obtain the finite element glass strength of each finite element laminated glass at the current glass thickness, and calculate the glass tensile stress at the optimal temperature holding time based on the finite element glass strength.

Specifically, the glass tensile stress is calculated by formula (1), which is as follows:

Among them, _σsingle represents the tensile stress of single-sided glass, m represents the number of finite element laminated glasses, ρ represents the bending coefficient of the mth finite element laminated glass, _σk represents the finite element glass strength at the current glass thickness, which is determined by the current glass material and glass thickness, h represents the thickness of the mth finite element laminated glass, γ represents the linear expansion coefficient of the mth finite element laminated glass at the optimal laminating temperature, and Δτ represents the glass stress change value corresponding to the change of adjacent heating temperature.

S403: adjusting the rolling rate and rolling pressure of the tempered laminated glass according to the tensile stress of the glass, and obtaining the laminating control data of the tempered laminated glass according to the adjustment result.

Specifically, according to the glass tensile stress, the rolling rate and rolling pressure of the tempered laminated glass are adjusted. For example, the greater the glass tensile stress of the finite element laminated glass, the lower the rolling rate and the greater the rolling pressure; the smaller the glass tensile stress of the finite element laminated glass, the higher the rolling rate and the smaller the rolling pressure, thereby obtaining the laminating control data of the tempered laminated glass according to the adjustment result.

It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
