[0030] As described in the background technology, the current vacuum system of laminated glass mainly uses manual vacuuming, which cannot detect whether the gas in the laminated glass is completely exhausted, so that the vacuum operation has no good data and judgment basis. Based on this, in order to solve the above problem, the embodiment of the present application provides a vacuum system for laminated glass, which can be assembled with a vacuum meter electrical control to cooperate with the judgment of whether the vacuum has been exhausted or leaking. Figure 1 A schematic diagram of a vacuum system for laminated glass provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the vacuum system may include:

[0031] A first gas tank 1 for evacuating a vacuum, wherein the first gas tank 1 is provided with a first vacuum pressure gauge for detecting a vacuum negative pressure value inside the first gas tank 1;

[0032] A second gas tank 2 for providing negative pressure power to the first gas tank 1, wherein the first gas tank 1 and the second gas tank 2 are connected via a gas tank pipeline;

[0033] A vacuum pipe 3 , one end of which is connected to the laminated glass to be vacuumed, and the other end of which is connected to the first gas tank 1 .

[0034] In this embodiment, the first gas tank 1 can be used to perform vacuum operation on laminated glass. The specific structure of the first gas tank 1 is not limited. For example, the first gas tank 1 can be equipped with a first vacuum pressure gauge for detecting the vacuum negative pressure value inside the first gas tank 1, and other devices can also be installed. The specific contents of other devices can be configured according to actual needs.

[0035] Among them, the first vacuum pressure gauge can be used to detect the vacuum negative pressure value inside the first gas tank 1. Furthermore, the value of the detected vacuum negative pressure value can be used to reflect the vacuum degree of the connected laminated glass. For example, when the vacuum negative pressure value inside the first gas tank 1 is a preset negative pressure value or is in a preset negative pressure range, it can be characterized that the vacuum degree of the connected laminated glass meets the process requirements. The specific values ​​of the preset negative pressure value and the preset negative pressure range can be configured by relevant personnel. For example, the preset negative pressure value can be 0.0, which is not limited in this embodiment.

[0036] The second gas tank 2 can be used to provide negative pressure power for the first gas tank 1. For example, the second gas tank 2 can use an internally configured vacuum pump to provide negative pressure power for the first gas tank 1 by pumping, so that when the first gas tank 1 evacuates the gas in the laminated glass according to the negative pressure power, the vacuum negative pressure value inside the first gas tank 1 and inside the laminated glass where the first gas tank is evacuating the vacuum is less than the preset negative pressure value. The specific composition and specific parameters of the second gas tank 2 are not limited. For example, the volume of the first gas tank 1 can be smaller than the volume of the second gas tank 2. In this embodiment, the first gas tank 1 can be a negative pressure gas tank with a volume of 0.3 cubic meters, and the second gas tank 2 can be a negative pressure gas tank with a volume of 0.4 cubic meters.

[0037] The first gas tank 1 and the second gas tank 2 may be connected via a gas tank pipeline, and the gas tank pipeline may be a pipeline connecting gas tanks, such as a gas tank pipeline and a connecting valve, or may be a connecting pipeline in other ways. The material and other information of the gas tank pipeline and the connecting valve are not limited here, as long as the connection between the first gas tank 1 and the second gas tank 2 can be achieved.

[0038] Furthermore, the vacuum system may further include a vacuum pipe 3, one end of which may be connected to the laminated glass to be vacuumed, and the other end of which may be connected to the first gas tank 1. The number of vacuum pipes 3 is not limited, and the specific number of vacuum pipes 3 may be increased or decreased as required. This embodiment does not limit the specific way in which the vacuum pipe 3 is connected to the laminated glass or the first gas tank 1, such as one end of the vacuum pipe 3 may be connected to the laminated glass through a vacuum nozzle, or the vacuum pipe 3 and the laminated glass may be connected through other airtight accessories.

[0039] In addition, the specific connection between the vacuum pipe 3 and the first gas tank 1 can be based on a device configured on the first gas tank 1, or can be made with the help of a vacuum suction nozzle and the like.

[0040] In some embodiments, the vacuum system may further include:

[0041] At least one one-way valve is connected to the first gas tank 1 , and each one-way valve is connected to the laminated glass through a corresponding vacuum pipe 3 .

[0042] Among them, the one-way valve can be used to control the vacuum operation of the first gas tank 1 on the laminated glass, such as the first gas tank 1 can be opened or closed to vacuum the air in the laminated glass, and the number of the one-way valves can correspond to the vacuum pipe 3, such as each one-way valve can be connected to the laminated glass through the corresponding vacuum pipe 3.

[0043] In some embodiments, the second gas tank 2 may be equipped with a second vacuum pressure gauge for detecting the vacuum negative pressure value inside the second gas tank 2, that is, the second vacuum pressure gauge may detect the vacuum negative pressure value inside the second gas tank 2. In specific applications, the second vacuum pressure gauge may reflect the vacuum degree of the laminated glass together with the first vacuum pressure gauge. For example, when the vacuum negative pressure value detected by the first vacuum pressure gauge is 0.0 and the vacuum negative pressure value detected by the second vacuum pressure gauge is greater than 0.0, it can be considered that the current laminated glass is in a vacuum state, otherwise it can be determined that the current laminated glass has not yet been evacuated to a vacuum state.

[0044] In some embodiments, the manner in which the first vacuum pressure gauge and the second vacuum pressure gauge display the detected vacuum negative pressure value is not limited, and can be determined according to the types of the first vacuum pressure gauge and the second vacuum pressure gauge. For example, the types of the first vacuum pressure gauge and the second vacuum pressure gauge can be the same, such as both are digital vacuum gauges or mechanical vacuum gauges. The types of the first vacuum pressure gauge and the second vacuum pressure gauge can also be different, such as any one of a digital vacuum gauge and a mechanical vacuum gauge. Optionally, the type of the first vacuum pressure gauge can be a digital vacuum gauge, and the type of the second vacuum pressure gauge can be a mechanical vacuum gauge.

[0045] In some embodiments, the second gas tank 2 is at least equipped with a control box, a vacuum pump and an air filter.

[0046] The control electric box is used to give a system prompt when the first vacuum pressure gauge detects that the vacuum negative pressure value inside the first gas tank 1 is a preset negative pressure value;

[0047] The air filter is used to filter the gas in the second gas tank 2;

[0048] The vacuum pump is used to provide negative pressure power for the first gas tank 1 and the second gas tank 2.

[0049] In a specific implementation, the second gas tank 2 may be configured with at least a control electrical box, a vacuum pump and an air filter, wherein information may be exchanged between the control electrical box and the first vacuum pressure gauge. For example, when the first vacuum pressure gauge detects that the vacuum negative pressure value inside the first gas tank 1 is a preset negative pressure value, the first vacuum pressure gauge may send a signal to the control electrical box, and then the control electrical box may issue a system prompt after receiving the signal. For example, the system prompt may be an alarm prompt or a display screen prompt, etc., to prompt relevant personnel that the laminated glass is currently in a vacuum state and that the vacuum pumping operation may be stopped, etc.

[0050] The air filter can be used to filter the compressed gas in the second gas tank 2. For example, the air filter can be a compressed air oil-water separator, which can be used to separate impurities such as condensed water and oil in the compressed air to preliminarily purify the compressed air. The vacuum pump can be understood as a device that can continuously inhale and discharge gas to achieve the purpose of exhausting gas, and can be used to provide negative pressure power for the first gas tank 1 and the second gas tank 2.

[0051] In some embodiments, a safety valve may be installed on one side of the second gas tank 2. The safety valve is mainly used to automatically open when the gas pressure inside the second gas tank 2 exceeds a set value to release excess gas to reduce the gas pressure inside the tank and prevent the gas tank from rupturing due to further increase in the gas pressure inside the tank.

[0052] In some embodiments, the bottom of the first gas tank 1 and / or the second gas tank 2 is at least provided with a drainage valve and a reinforcement device.

[0053] It can be considered that, since the compressed air has a high temperature, it will gradually cool down when entering the first gas tank 1 and / or the second gas tank 2, causing the moisture in the air to condense out, so the configured drain valve can be used to discharge the condensed moisture to ensure the safety of the gas tank and extend the service life of the gas tank. The reinforcement device can be used to reinforce the first gas tank 1 and / or the second gas tank 2, such as the reinforcement device can be a gas tank base, etc., which can be used to support the weight of the gas tank and ensure the stability of the gas tank.

[0054] Figure 2A schematic diagram of the structure of another vacuum system for laminated glass provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the vacuum system may include a negative pressure gas tank 5 (i.e., a first gas tank) with a volume of 0.3 cubic meters, a negative pressure gas tank 6 (i.e., a second gas tank) with a volume of 0.4 cubic meters, and a vacuum pipe 8 (only one vacuum pipe is shown in the figure), one end of the vacuum pipe 8 is connected to the laminated glass 4 to be vacuumed through a vacuum nozzle 7, and the other end of the vacuum pipe 8 is connected to the one-way valve 9 of the negative pressure gas tank 5. Furthermore, the vacuum system provided in this embodiment includes nine one-way valves 9 connected to the negative pressure gas tank 5, and each one-way valve 9 can be connected to the laminated glass 4 through the corresponding vacuum pipe (only one vacuum pipe is shown in the figure).

[0055] Among them, the negative pressure gas tank 5 can be equipped with a vacuum pressure gauge 10 (i.e., a first vacuum pressure gauge) for detecting the vacuum negative pressure value inside the negative pressure gas tank 5, and the type of the vacuum pressure gauge 10 can be a digital vacuum gauge; the negative pressure gas tank 6 can be used to provide negative pressure power for the negative pressure gas tank 5, and the negative pressure gas tank 6 is equipped with a vacuum pressure gauge 11 (i.e., a second vacuum pressure gauge) for detecting the vacuum negative pressure value inside the negative pressure gas tank 6, and the type of the vacuum pressure gauge 11 can be a mechanical vacuum gauge.

[0056] The negative pressure gas tank 6 is equipped with a control box 14, an air filter 15 and a vacuum pump 16. The control box 14 can be used to prompt the system when the vacuum pressure gauge 10 detects that the vacuum negative pressure value inside the negative pressure gas tank 5 is 0.0 (i.e., the preset negative pressure value); the air filter 15 can be used to filter the gas in the negative pressure gas tank 6; the vacuum pump 16 can be used to provide negative pressure power for the negative pressure gas tank 5 and the negative pressure gas tank 6. At the same time, a safety valve 17 is also installed on the right side of the negative pressure gas tank 6.

[0057] The negative pressure gas tank 5 and the negative pressure gas tank 6 are connected through the gas tank pipeline 12 and the connecting valve 13, and the bottom of the negative pressure gas tank 5 and the negative pressure gas tank 6 can be equipped with a drainage valve 18 and an equipment installation reinforcement iron block 19 (i.e., a reinforcement device) ( Figure 2 Only the drainage valve and equipment installation reinforcement iron block are shown in the negative pressure gas tank 6).

[0058] Figure 3 A schematic diagram of a process of vacuuming laminated glass provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the laminated double-layer glass can be first sealed with plastic transparent tape by heating, and then the vacuum device and vacuum pipeline device can be installed for reinforcement. After the installation is completed, the vacuum operation can be started. At the same time, the configured vacuum pressure gauge can output the vacuum negative pressure value of the current negative pressure gas tank. When the vacuum negative pressure value outputs 0.0, it can be determined that the laminated double-layer glass is in a vacuum state, the vacuum operation is ended and the subsequent production process continues.

[0059] In summary, the vacuum pumping system for laminated glass provided in this embodiment has at least the following beneficial technical effects: the first gas tank is equipped with a first vacuum pressure gauge for detecting the vacuum negative pressure value inside the first gas tank, which can provide better data and judgment basis for the vacuum pumping operation, so as to accurately judge whether the vacuum state of the laminated glass is qualified or not, improve the production qualification rate of laminated glass, and then ensure the stability of product quality.
