Description

Technical Field

[0001] This utility model relates to the field of insulated glass inflation technology, and in particular to an insulated glass inflation control device. Background Technology

[0002] Insulating glass typically requires inflation to achieve certain properties. Common automatic pre-compression and inflation equipment uses an inflation content detector to monitor the inflation content at the air outlet of the insulating glass unit, thus controlling the inflation process. However, since the inflation process essentially involves the replacement of existing air with new gas, the movement of the new gas and the existing air inside the glass is irregular, and the concentration at the outlet is unstable. Furthermore, different insulating glass units have different production configurations, which can lead to frequent errors in the inflation content detector. Ultimately, the inflation content inside the insulating glass unit may be insufficient, affecting the inflation stability and consequently the quality of the insulating glass unit. Utility Model Content

The thickness detection module is used to measure the thickness of the insulating glass placed inside the inflation chamber. The detection signal output terminal of the thickness detection module is electrically connected to the signal receiving terminal of the timing control unit.

[0007] Furthermore, the thickness detection module includes two pressure plates that slide closer or further apart relative to each other. The two pressure plates are respectively bonded to the two sides of the insulating glass. A distance sensing unit is provided between the two pressure plates, and the distance sensing signal output terminal of the distance sensing unit is electrically connected to the signal receiving terminal of the timing control unit.

[0008] Furthermore, several of the pressure plates are arranged to form a pressure plate group, and a glass clamping space is formed between each pair of pressure plates. A pressure application device is provided at one end of the pressure plate group.

[0010] Furthermore, the timing control unit includes a parameter input module and a calculation module, and the editing module and the thickness detection module are connected to the calculation module via the parameter input module for data transmission.

[0011] Beneficial effects: The insulating glass inflation control device of this utility model calculates the corresponding inflation time by actively inputting the glass configuration and real-time thickness detection, and then controls the inflation time by a set timing control program to ensure that the inflation volume meets the standard after inflation, improve the inflation stability, and guarantee the quality of the insulating glass. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of a hollow glass inflation control device according to the present invention. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] As attached Figure 1 The aforementioned insulating glass inflation control device includes an inflation chamber 1, an inflation module 2, an editing module 3, and a timing control unit 4. The signal output terminal of the editing module 3 is electrically connected to the signal receiving terminal of the timing control unit 4. The inflation module 2 is equipped with a switching valve 7, and the control signal output terminal of the timing control unit 4 is electrically connected to the control signal receiving terminal of the switching valve 7. The inflation chamber is used to limit the size of the insulating glass unit and can be equipped with a limiting structure for positioning, installation, and fixation. The editing module inputs corresponding parameters according to the configuration of the insulating glass unit, and the timing control unit calculates the inflation time. Based on this time, the opening and closing interval of the switching valve 7 is controlled to strictly control the inflation time, ensuring sufficient inflation and avoiding unstable inflation volume.

[0015] The parameters input into the editing module 3 include the glass's planar dimensions, stiffness and strength requirements, and thermal insulation requirements. The editing module 3 uses a touchscreen, while the timing control unit 4 is implemented by adding a PLC to an existing automatic pre-compression and inflation device, importing a self-written time setting control program, inputting the glass configuration via the touchscreen, having the PLC calculate the inflation duration, and executing the set control program to complete the timing control of the inflation duration.

[0016] A thickness detection module 5 is installed inside the inflation chamber 1. The thickness detection module 5 is used to measure the thickness of the insulating glass 6 placed inside the inflation chamber 1. The detection signal output terminal of the thickness detection module 5 is electrically connected to the signal receiving terminal of the timing control unit 4. By measuring the actual thickness of the glass inside the inflation chamber through the thickness detection module 5, it is easier to calculate the actual inflation volume of the insulating glass. Then, based on the air flow rate of the corresponding switch valve 7, the actual inflation time can be calculated, thereby improving the accuracy and stability of the inflation volume.

[0017] Preferably, the thickness detection module 5 includes two pressure plates 51 that slide relatively close to or far apart. The two pressure plates 51 are respectively attached to the two single sheets on both sides of the insulating glass 6. A distance measuring sensing unit 52 is disposed between the two pressure plates 51. The distance measuring signal output terminal of the distance measuring sensing unit 52 is electrically connected to the signal receiving terminal of the timing control unit 4. During inflation, the insulating glass is simply inserted between the two pressure plates, and moderate pressure is applied to reduce the distance between the two pressure plates to a constant value. At this time, the distance between the two plates measured by the distance measuring sensing unit is the thickness of the insulating glass. The thickness of the middle partition frame is calculated based on the thickness of the single sheets on both sides, and the volume of the inflation cavity is calculated based on the glass plane dimensions and the partition frame thickness, thereby obtaining the maximum inflation volume.

[0018] In this embodiment, several pressure plates 51 are arranged to form a pressure plate group, with a glass clamping space formed between each pair of pressure plates 51. A pressure applying device 53 is provided at one end of the pressure plate group. By setting this pressure plate group within a single inflation chamber 1, multiple insulated glass units of the same plane size but different thicknesses can be inflated simultaneously within the single inflation chamber. The actual thickness of each insulated glass unit can be measured separately. The pressure applying device 53 is used to drive multiple pressure plates to clamp synchronously, simultaneously detecting the glass thickness and fixing the glass, ensuring the stability of the glass during the inflation process.

[0019] The inflation module 2 is equipped with an inflation tube 21 for each glass clamping space, and each inflation tube 21 is equipped with a switch valve 7. Each switch valve 7 is electrically connected to a timing control unit 4, and multiple timing control units 4 are electrically connected to the editing module 3. Each of the multiple glass panes clamped by the pressure plate assembly is individually inflated through a separate inflation tube, with the inflation amount and duration controlled by its own switch valve. The editing module can edit the basic parameters for each of the multiple timing control units.

[0020] The timing control unit 4 includes a parameter input module 41 and a calculation module 42. The editing module 3 and the thickness detection module 5 are connected to the calculation module 42 via the parameter input module 41 for data transmission. The editing module 3 retrieves the corresponding inflation percentage from the database based on input parameters such as stiffness, strength, and thermal insulation. It then transmits this inflation percentage and the glass plane dimensions to the corresponding parameter input module 41. Simultaneously, the parameter input module 41 receives the actual thickness value from the thickness detection module 5. The calculation module first calculates the inflation volume, then calculates the actual inflation volume using the inflation volume and inflation percentage, and finally calculates the inflation time using the valve flow rate and the actual inflation volume. After inflation begins, the calculated inflation time is used to start the timer. Once the timer finishes, the valve is closed to complete the inflation process, strictly controlling the glass inflation volume to ensure the quality of the insulated glass.

[0021] The above are merely preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
