Description

Technical Field

[0001] This application relates to the technical field of glass forming, and in particular to a multilayer insulating glass forming system. Background Technology

[0002] Multi-layer insulated glass, with its excellent heat insulation, sound insulation, and anti-condensation properties, has been widely used in various fields such as building doors and windows, curtain walls, and cold storage. Its forming process involves a series of steps, including glass cleaning, inspection, multi-layer glass pressing, and edge sealing. The degree of automation, inspection accuracy, and process continuity of the forming system directly determine the product quality and production efficiency of insulated glass.

[0003] Before lamination, the glass needs to undergo a visual inspection to ensure its cleanliness. Currently, the visual inspection of glass is still mainly done manually, with operators visually inspecting the glass.

[0004] Multi-layered glass comes in a variety of specifications, with varying heights and widths, naturally leading to different inspection ranges and areas. For some glass sizes, operators can simply scan the entire glass area for inspection. However, for smaller glass sizes with lower heights and edges blending into the production line background, operators need to bend over or squat to inspect the glass. This increases the intensity of the inspection but also increases the risk of missed or incorrect inspections, thus affecting the final glass quality. Summary of the Invention

[0005] To address the aforementioned technical problems, this application provides a multilayer insulating glass forming system.

[0006] The multi-layer insulating glass forming system provided in this application adopts the following technical solution: A multilayer insulating glass forming system includes a conveying device and a cleaning device, a testing device, a pressing device, and an edge sealing device arranged sequentially along the conveying direction of the conveying device. The conveying device includes a plurality of rollers, and the testing device includes a testing back plate with a plurality of testing backlights. Gaps are left between the rollers, and a lifting roller located in the gap is provided below the testing back plate. The lifting roller is vertically slidably connected to the testing back plate.

[0007] By adopting the above technical solution, the glass is transported to the inspection backplate via a conveyor device for visual inspection. The lifting rollers raise the glass upwards, bringing it to the operator's normal height. This allows the operator to inspect the entire glass without bending or squatting, and provides a wider field of view, facilitating more thorough inspection. Furthermore, the bottom of the glass, positioned in the center of the inspection backplate, is illuminated by the inspection backlight, making inspection even brighter and easier.

[0008] Preferably, the detection back plate is provided with a plurality of guide wheels, including a traveling wheel whose transmission direction is consistent with the roller conveying direction, and a detection wheel whose transmission direction is consistent with the sliding direction of the lifting roller.

[0009] By adopting the above technical solution, when the lifting roller moves upward to lift the glass, the back of the glass contacts the detection wheel, which guides the glass lifting process and ensures stability. The traveling wheels guide the horizontal movement of the glass, ensuring stability during glass transportation.

[0010] Preferably, the detection back plate has several switching holes perpendicular to the detection back plate, and the guide wheel is slidably connected in the switching holes. The guide wheel is slidably connected in the switching holes by the switching push rod.

[0011] By adopting the above technical solution, when the glass slides horizontally to the detection device, the traveling wheels retract into the switching hole and extend out of the switching hole to contact the glass, providing support and guidance. When the lifting rollers vertically lift the glass, the detection wheel extends from the switching hole to contact the glass, providing support and guidance, while the traveling wheels retract into the switching hole. The traveling wheels and detection wheels can slide within the switching hole, thus switching between them to meet the support requirements for different directions of glass movement.

[0012] Preferably, the walking wheels and detection wheels are arranged in pairs to form a guide group, that is, a guide group includes a walking wheel and a detection wheel. The walking wheels and detection wheels are arranged at intervals on the detection back plate to form strip-shaped guide belts. The detection back plate has several parallel guide belts along the vertical direction. The guide wheels are aligned vertically to form guide columns.

[0013] By adopting the above technical solution, the walking wheels and the detection wheels are set at intervals, and the walking wheels and the detection wheels are evenly distributed on the detection back plate, so as to be able to adapt to a variety of different specifications of glass.

[0014] Preferably, a detection module and a pressure sensor for detecting glass are provided between the guide wheel and the switching hole. The detection module is electrically connected to the detection push rod and the travel push rod. One guide group contains two detection modules and two pressure sensors, and each detection module in each guide group is electrically connected to the two pressure sensors in that group. The detection module includes... When the device is powered off, the detection module is in a powered-off state if neither of the two pressure sensors detects glass. In standby mode, one pressure sensor detects glass, while the other pressure sensor does not detect glass, and the detection module located on the same guide wheel as the pressure sensor is in standby mode. In the supported state, one pressure sensor does not detect glass, while the other pressure sensor detects glass and the detection module located on the same guide wheel as the pressure sensor is in the supported state. When switching states, the detection module is in the off state when both pressure sensors detect glass.

[0015] By adopting the above technical solution, when the glass has not moved to the detection backplate, all detection wheels are retracted into the switching holes, and all traveling wheels extend out of the switching holes, waiting for the glass to arrive. When the glass has completely moved to the detection backplate and stopped moving, the detection module of the traveling wheel supporting the glass is in a supported state, and the detection module of the detection wheel in the same guide group as the traveling wheel is in a standby state. At this time, the controller controls the detection wheel in the standby state to extend out of the switching hole to support the glass, and retracts the traveling wheel in the supported state to a standby state. At this time, the lifting roller lifts the glass vertically. The division of multiple states corresponds to the relationship between the detection module, the guide wheel, and the glass, which facilitates the issuance and execution of subsequent commands and ensures the stability of the glass operation process.

[0016] Preferably, the detection backplate is provided with an initial detection area, the size of which is the same as the area of ​​the insulating glass. The switching push rod located in the same switching hole as the detection module can only be controlled to retract when the detection module in the initial detection area is in a switching state.

[0017] By employing the above technical solution, the glass moves to the detection backplate, forming an initial detection zone. At this point, the traveling wheels within this zone support the glass. To switch between the traveling wheels and the detection wheels, the detection wheels must first extend to support the glass before the traveling wheels can retract. This sequence cannot be reversed; otherwise, the glass may tilt and collide with the detection backplate, shattering. Therefore, only when both the traveling wheels and the detection wheels simultaneously contact and support the glass, ensuring its stability, can either the traveling wheel or the detection wheel retract. This method limits the timing of the guide wheel retraction, thereby ensuring the safety and stability of the glass.

[0018] Preferably, the guide belt includes a detection belt located within the initial detection area and an undetected belt located outside the initial detection area, with all guide wheels on the same detection belt operating synchronously.

[0019] By adopting the above technical solution, the guide belt occupied by the initial detection area becomes the detection belt that supports the glass, while the remaining undetected belts do not contact the glass and do not need to perform any actions, thus reducing energy consumption. All guide wheels on the detection belt move synchronously, that is, after all the detection wheels on the detection belt extend simultaneously, all the traveling wheels retract, so that the glass can be vertically lifted.

[0020] Preferably, the inner wall of the switching hole is provided with a negative pressure suction hole, a switching block is slidably connected in the switching hole, and the guide wheel is installed on the switching block. When the guide wheel is fully extended out of the switching hole, the switching block blocks the negative pressure suction hole. When the guide wheel is retracted into the switching hole, the switching block opens the negative pressure suction hole.

[0021] By adopting the above technical solution, after the guide wheel is retracted into the switching hole, the negative pressure suction hole is opened, and negative pressure suction is generated in the negative pressure suction hole to adsorb the glass, thereby further improving the stability of the glass movement process.

[0022] In summary, this application includes the following beneficial technical effects: With the installation of inspection wheels and lifting rollers, operators can inspect the entire glass without bending over or squatting. Furthermore, the operator's field of vision is wider in a normal state, allowing for a larger observation range. This facilitates more careful inspection of the glass and improves the inspection results. Attached Figure Description

[0025] The present application will be further described in detail below with reference to all the accompanying drawings.

[0026] Example

[0027] This application discloses a multilayer insulating glass forming system, referring to... Figure 1 The system includes a conveying device 1 and a cleaning device 2, an inspection device 3, a pressing device 4, and an edge-sealing device 5, which are sequentially connected along the conveying direction of the conveying device 1. These devices work together to complete the integrated forming process of cleaning, inspection, pressing, and edge sealing of multi-layer insulating glass. The conveying device 1 includes several parallel, spaced, rotatably connected rollers 6. The transmission direction of the rollers 6 is consistent with the glass conveying direction, used to smoothly convey the glass to be processed, achieving continuous glass transfer between the devices.

[0028] Reference Figure 1 The inspection device 3 includes a vertically arranged inspection backplate 7, which is a flat plate structure. Several inspection backlights 8 are evenly distributed on the side facing the glass. The inspection backlights 8 are high-brightness LEDs, used to provide sufficient and uniform light for glass inspection, facilitating the operator's observation of surface defects.

[0029] Reference Figure 1 A gap 9 is left between the rollers 6, and the gap 9 is evenly distributed along the glass conveying direction. Several lifting rollers 10 are provided below the detection back plate 7, and the lifting rollers 10 are located within the gaps 9. The lifting rollers 10 are vertically slidably connected to the detection back plate 7. The lifting rollers 10 adopt an electric lifting structure and can slide up and down in the vertical direction to realize the lifting and lowering of the glass.

[0030] Reference Figure 1 The glass to be processed is conveyed to the cleaning device 2 via rollers 6 of the conveying device 1. After cleaning the dust and stains on the glass surface, it is conveyed to the inspection device 3 for visual inspection. When the glass is conveyed to the front of the inspection backplate 7, the lifting roller 10 is raised and extends from the gap 9 between the rollers 6, lifting the glass upwards to a normal operating height for the operator. The operator can then conduct a comprehensive inspection of the glass without bending over or squatting. Furthermore, the operator has a wider field of vision and a broader observation range in a normal standing posture, facilitating a more detailed inspection of minor defects and cracks on the glass surface. Simultaneously, the bottom of the glass is raised to the middle position of the inspection backplate 7, ensuring sufficient illumination from the inspection backlight 8, further enhancing the convenience and accuracy of the inspection. After inspection, the lifting roller 10 falls back down, the glass is placed back on the rollers 6, and continues to be conveyed to the subsequent pressing device 4 and sealing device 5 to complete the subsequent forming process.

[0031] Reference Figure 1 and Figure 2The inspection backplate 7 has several guide wheels 11 on the side facing the glass. These guide wheels 11 are of two types: traveling wheels 12 and inspection wheels 13. The traveling wheels 12 have the same transmission direction as the rollers 6, guiding the horizontal transport of the glass. The inspection wheels 13 have the same transmission direction as the lifting rollers 10, guiding the vertical lifting of the glass. When the lifting rollers 10 move upwards to lift the glass, the back of the glass contacts the inspection wheels 13. The inspection wheels 13 guide the lifting process, preventing tilting or deviation and ensuring stability. When the glass is transported horizontally, the traveling wheels 12 contact the back of the glass, guiding its horizontal movement and preventing deviation during transport. This ensures stability during transport and lays the foundation for precise subsequent inspection, pressing, and sealing processes.

[0032] Reference Figures 1 to 3 The detection back plate 7 has several switching holes 14 perpendicular to it, which are evenly distributed on the detection back plate 7. A switching block 19, controlled by a switching push rod 15, is slidably connected inside the switching hole 14. A guide wheel 11 is mounted on the switching block 19, and the switching block 19 can slide along the switching hole 14 together with the guide wheel 11.

[0033] Reference Figures 1 to 3 The inner wall of the switching hole 14 is provided with several negative pressure suction holes 20. These holes 20 are connected to external negative pressure equipment and can generate negative pressure suction. When the guide wheel 11 is fully extended out of the switching hole 14, the switching block 19 blocks the negative pressure suction holes 20, and the holes 20 do not work. When the guide wheel 11 retracts into the switching hole 14, the switching block 19 opens the negative pressure suction holes 20, and the holes 20 generate negative pressure suction. After the guide wheel 11 retracts into the switching hole 14, the negative pressure suction holes 20 open, adsorbing the back of the glass through negative pressure suction, preventing the glass from shifting or shaking during horizontal transport or vertical lifting. It also helps to fix the glass, providing a stable support foundation for detection, switching, and other operations.

[0034] When the glass slides horizontally to the detection device 3, the traveling wheel 12 extends from the switching hole 14 and contacts the back of the glass, providing support and horizontal guidance. When the lifting roller 10 vertically lifts the glass, the detection wheel 13 extends from the switching hole 14 and contacts the back of the glass, providing support and vertical guidance. Simultaneously, the traveling wheel 12 retracts into the switching hole 14 to avoid interfering with the glass lifting action. By switching between the traveling wheel 12 and the detection wheel 13, the support and guidance requirements for both horizontal glass conveying and vertical lifting can be fully met, improving the equipment's adaptability.

[0035] Reference Figures 1 to 3The traveling wheel 12 and the detection wheel 13 are arranged in pairs to form a guide group 16, that is, a guide group 16 includes one traveling wheel 12 and one detection wheel 13. The traveling wheel 12 and the detection wheel 13 are arranged at intervals on the detection back plate 7 to form strip-shaped guide belts 17, which extend horizontally. Several parallel guide belts 17 are provided on the detection back plate 7 in the vertical direction, and all the guide wheels 11 are aligned vertically to form guide columns 18.

[0036] Reference Figures 1 to 3 The traveling wheels 12 and the detection wheels 13 are evenly distributed, and the guide belts 17 and the guide columns 18 are interlaced, so that the guide wheels 11 are evenly distributed on the detection back plate 7. This can adapt to a variety of different specifications and sizes of glass, improve the versatility of the system, eliminate the need to adjust the guide structure for different specifications of glass, and reduce the difficulty of operation.

[0037] Reference Figures 1 to 3 A detection module and a pressure sensor are provided between the guide wheel 11 and the switching hole 14. The detection module is used to detect the position of the glass, and the pressure sensor is used to detect the contact pressure between the guide wheel 11 and the glass. The detection module is electrically connected to the switching push rod 15 and can control the extension and retraction of the switching push rod 15, thereby controlling the extension and retraction of the guide wheel 11.

[0038] Reference Figures 1 to 3 Each guide group 16 contains two detection modules and two pressure sensors. Each detection module within each guide group 16 is electrically connected to the two pressure sensors within that group, and can receive detection signals from the two pressure sensors, adjusting its operating state based on signal feedback. The detection module has four operating states, as follows: 1. Power-off state: When neither pressure sensor detects glass, the detection module is in the power-off state. At this time, the guide wheel 11 remains in its initial state and does not perform any action. The initial state of the traveling wheel 12 is that it extends out of the switching hole 14, and the initial state of the detection wheel 13 is that it retracts into the switching hole 14.

[0039] 2. Standby state: When one pressure sensor detects glass and the other pressure sensor does not detect glass, the detection module located on the same guide wheel 11 as the pressure sensor that detected glass is in standby state, ready to respond to the switching command at any time.

[0040] 3. Support state: When one pressure sensor does not detect glass, but the other pressure sensor detects glass, and the detection module is located on the same guide wheel 11 as the pressure sensor that detected glass, the guide wheel 11 remains extended to support the glass.

[0041] 4. Switching state: When both pressure sensors detect glass, the detection module is in the switching state, and the switching action of guide wheel 11 can be executed at this time.

[0042] When the glass has not moved to the detection backplate 7, all detection modules are in the off state. All detection wheels 13 retract into the switching holes 14, and all traveling wheels 12 extend out of the switching holes 14, waiting for the glass to arrive. When the glass has completely moved to the detection backplate 7 and stopped moving, all detection modules corresponding to the traveling wheels 12 that are in contact with the glass are in a supported state, and the detection modules corresponding to the detection wheels 13 that are in the same guide group 16 as these traveling wheels 12 are in a standby state. At this time, the controller controls the detection wheels 13 in the standby state to extend out of the switching holes 14, contact the glass, and support the glass. After the detection wheels 13 are stably supported, the controller controls the traveling wheels 12 in the supported state to retract into the switching holes 14, and their corresponding detection modules switch to the standby state. Then the lifting roller 10 lifts upward to vertically lift the glass, and the detection wheels 13 guide the lifting action. Through the division of multiple states, the positional relationship between the detection modules, guide wheels 11, and glass is accurately matched, which facilitates the issuance and execution of subsequent commands and ensures the stability of the glass operation process.

[0043] Reference Figures 1 to 3 The detection backplate 7 has an initial detection area, the size of which is the same as the area of ​​the insulating glass to be processed, used to confirm whether the glass has completely entered the detection area. The switching push rod 15 located in the same switching hole 14 as the detection module can only be controlled to retract when the detection module in the initial detection area is in the switching state.

[0044] The timing of the retraction of the guide wheel 11 is strictly limited to prevent glass tilting and damage. When the glass moves to the detection backplate 7 and completely covers the initial detection area, both the traveling wheel 12 and the detection wheel 13 in the initial detection area are in contact with the glass, and the corresponding detection module is in a switching state. Only at this time can the switching push rod 15 be controlled to retract, realizing the switching between the traveling wheel 12 and the detection wheel 13. This design ensures the sequential nature of the switching action—the detection wheel 13 must be extended to support the glass before the traveling wheel 12 can be retracted. This avoids the glass losing support and tilting due to a reversed sequence, which could cause it to collide with and shatter against the detection backplate 7, thus ensuring the safety of the glass and the stability of the detection process.

[0045] Reference Figures 1 to 3The guide belt 18 includes a detection belt and an undetected belt 21, where the detection belt is located within the initial detection zone and the undetected belt 21 is located outside the initial detection zone. All guide wheels 11 on the same detection belt move synchronously. After the glass fully enters the initial detection zone, only the detection belt within the initial detection zone participates in support and guidance; the remaining undetected belts 21 do not contact the glass and do not need to perform any actions, effectively reducing equipment energy consumption. Simultaneously, all guide wheels 11 on the same detection belt extend or retract synchronously; that is, after all the detection wheels 13 on the detection belt extend and stably support the glass, all the traveling wheels 12 retract. The detection wheels located above the initial detection zone provide support for subsequent glass lifting, preventing uneven local force that could cause tilting and facilitating stable vertical lifting of the glass.

[0046] The implementation principle of a multi-layer insulating glass forming system according to an embodiment of this application is as follows: The glass to be processed is conveyed to the cleaning device 2 via rollers 6 of the conveying device 1. After surface cleaning, it continues to be conveyed to the detection device 3. When the glass is conveyed horizontally, in the initial state, the traveling wheel 12 extends and the detection wheel 13 retracts. The traveling wheel 12 guides the glass horizontally, and the glass gradually enters the initial detection area. When the glass completely covers the initial detection area, both the traveling wheel 12 and the detection wheel 13 in the initial detection area are in contact with the glass. The detection module is in a switching state. The controller controls the detection wheel 13 to extend synchronously and the traveling wheel 12 to retract synchronously. The switching block 19 opens the negative pressure suction hole 20, and the negative pressure suction adsorbs the glass. Subsequently, the lifting roller 10 lifts the glass from the gap 9, raising the glass to the operator's normal operating height. The detection wheel 13 guides the glass lifting, and the detection backlight 8 illuminates the glass, allowing the operator to perform a comprehensive inspection of the glass surface. After the inspection is completed, the lifting roller 10 falls back, the glass is placed back on the roller 6, the inspection roller 13 retracts, the traveling roller 12 extends, and the glass continues to be conveyed to the pressing device 4 to complete the multi-layer glass pressing, and then the edge sealing device 5 completes the edge sealing, finally forming a multi-layer insulated glass product.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
