Technical Field
[0001] This application relates to the field of architectural glass quality testing technology, and in particular to an auxiliary tooling for detecting the dew point of insulated glass. Background Technology
[0002] Insulating glass is a key material for energy conservation in modern buildings. Its sealing performance directly affects the heat insulation, sound insulation and service life. At present, the industry generally uses the dew point test method to evaluate the sealing performance of insulating glass, that is, to test whether water vapor condenses inside the glass spacer by simulating a low temperature environment.
[0003] The traditional testing method is manual dry ice spraying. With the improvement of building energy efficiency standards, the production of insulated glass has surged. The manual dry ice spraying method is inefficient and highly dependent on manual labor, making it difficult to meet the needs of large-scale production. In recent years, automated testing equipment has gradually become more widespread, but it still has insufficient adaptability due to the diverse requirements of glass size.
[0004] Therefore, this application provides an auxiliary tooling for detecting the dew point of insulating glass. Utility Model Content
[0005] To address the shortcomings of existing technologies, this application provides an auxiliary tooling for dew point testing of insulating glass, which overcomes the deficiencies of existing technologies. It aims to solve the problem that the traditional testing method is the manual handheld dry ice spray method. With the improvement of building energy efficiency standards, the production of insulating glass has surged. The manual handheld dry ice spray method is inefficient and highly dependent on manual labor, making it difficult to meet the needs of large-scale production. In recent years, automated testing equipment has gradually become popular, but it still has insufficient adaptability due to the diverse requirements of glass size.
[0006] To achieve the above objectives, this application provides the following technical solution: an auxiliary tooling for detecting the dew point of insulating glass, comprising a base plate, a support frame fixedly installed at the top of the base plate, a cooling spray pipe fixedly installed at the top of the support frame, a displacement mechanism provided at the top of the base plate, two sets of clamping mechanisms provided above the displacement mechanism, each clamping mechanism comprising a lower clamping arm and an upper clamping arm, a spring hinge installed at the connection between the lower and upper clamping arms, a fixed shaft provided in the middle of the spring hinge, adjustment mechanisms connected to both ends of the fixed shaft, both the lower and upper clamping arms being hinged to the fixed shaft, and a rubber layer fixedly installed on the clamping surfaces of both the lower and upper clamping arms.
[0007] By adopting the above technical solution, the insulating glass to be tested is placed above the displacement mechanism. The position of the clamping mechanism is adjusted by the adjustment mechanism. Then, the upper clamping arm is pressed, the lower clamping arm is pressed against the lower edge of the glass, and the upper clamping arm is pressed against the upper edge of the glass. The upper clamping arm is released, and the elasticity of the spring hinge causes the lower and upper clamping arms to automatically clamp the glass. The rubber layer improves the protection effect of the glass during clamping. Then, the cooling spray pipe is connected to the external liquid nitrogen storage tank, and cold air is sprayed through the cooling spray pipe to simulate a low temperature environment. The displacement mechanism moves the glass so that different parts of the glass can be evenly sprayed with mist. Then, the sealing performance of the glass is judged. By adapting the clamping mechanism to the edges of glass with different thicknesses, the outer surface of the glass is automatically sprayed, which improves the detection efficiency.
[0008] As a preferred technical solution of this application, the displacement mechanism includes two sets of electric slides, both sets of electric slides are fixedly installed on the top of the base plate, the sliding end of the electric slides is slidably connected to an electric slider, and the top of the two sets of electric sliders is fixedly installed with a bearing plate.
[0009] By adopting the above technical solution, two sets of electric sliders move linearly along the corresponding electric slides, thereby driving the support plate, two sets of clamping mechanisms and the clamped insulating glass to move. This achieves the purpose of the insulating glass passing under the cooling nozzle at a uniform speed and receiving the cold air sprayed by the cooling nozzle, thus improving the accuracy of subsequent testing.
[0010] As a preferred technical solution of this application, an extension frame is fixedly installed on the top of the support frame, an infrared thermal imager is fixedly installed on the bottom of the extension frame, and a controller is fixedly installed on one side of the support frame, the controller being electrically connected to the infrared thermal imager.
[0011] By adopting the above technical solution, the insulating glass held by the two clamping mechanisms is driven by the displacement mechanism to pass uniformly under the cooling nozzle and receive the cold air sprayed by the cooling nozzle. Then, the insulating glass continues to pass uniformly under the infrared thermal imager. The infrared thermal imager is model FLIRE8Pro, which can penetrate the glass surface to reflect interference and directly display the temperature anomaly area caused by internal water vapor condensation, thus improving the accuracy of glass dew point detection.
[0012] As a preferred embodiment of this application, the adjustment mechanism includes a support, which is fixedly installed on the top of the bearing plate. A motor base is fixedly installed on the top of the support, and a reciprocating motor is fixedly installed on the top of the motor base. Both output ends of the reciprocating motor are rotatably connected to the support with screws. A movable block is threadedly connected to the outer surface of the screw. An electric push rod is fixedly installed on one side of the movable block. A connecting frame is fixedly installed on the telescopic end of the electric push rod, and both ends of the fixed shaft are fixedly installed to the connecting frame.
[0013] By adopting the above technical solution, when clamping glass of different sizes, the reciprocating motor drives two sets of screws to rotate, causing the two sets of movable blocks to move closer or further apart under the action of the screws. The position of the connecting frame and the fixed shaft can be further adjusted by extending and retracting the electric push rod, thereby adjusting the position of the two sets of clamping mechanisms. This is beneficial for adapting to insulated glass of different sizes and improves the applicability during use.
[0014] As a preferred technical solution of this application, a number of spring support plates are installed at the top of the bearing plate on one side of the support, and a telescopic guide rod is provided inside the spring support plate.
[0015] By adopting the above technical solution, the bottom surface of the glass is supported by several sets of spring support plates, and the glass is supported by two sets of clamping mechanisms, which further improves the stability of fixing the glass.
[0016] As a preferred embodiment of this application, pressure sensors are fixedly installed on the clamping surfaces of both the lower and upper clamping arms. The pressure sensors are located inside the rubber layer and are electrically connected to the controller.
[0017] By adopting the above technical solution, the pressure sensor detects the force of the lower and upper clamping arms when clamping the glass and feeds the pressure signal back to the controller, which avoids excessive clamping force that damages the glass or insufficient clamping force that causes the glass to loosen, thus improving the safety and stability of the detection process.
[0018] As a preferred technical solution of this application, the bottom of the support is provided with a guide groove, and the bottom end of the movable block is fixedly installed with a guide block, which is slidably connected in the guide groove.
[0019] By adopting the above technical solution, the movable block moves and drives the guide block to slide in the guide groove, thus guiding the movable block during displacement and improving the stability when adjusting the distance between the two sets of clamping mechanisms.
[0020] As a preferred technical solution of this application, several sets of anti-slip toothed strips are fixedly connected to the opposite surfaces of the two sets of rubber layers.
[0021] By adopting the above technical solution, the friction between the rubber layer and the insulating glass is further increased by several sets of anti-slip toothed strips, which further improves the stability when clamping the insulating glass.
[0022] The beneficial effects of this application are: 1. Place the insulating glass to be tested above the displacement mechanism. Adjust the position of the clamping mechanism using the adjustment mechanism. Then press the upper clamping arm, align the lower clamping arm with the lower edge of the glass, and the upper clamping arm with the upper edge of the glass. Release the upper clamping arm, and the elasticity of the spring hinge will cause the lower and upper clamping arms to automatically clamp the glass. The rubber layer enhances the protection effect during glass clamping. Then, connect the cooling spray pipe to the external liquid nitrogen storage tank and spray cold air through the cooling spray pipe to simulate a low-temperature environment. The displacement mechanism moves the glass, ensuring that different parts of the glass are evenly sprayed with mist. Then, the sealing performance of the glass is judged. By adapting the clamping mechanism to the edges of glass with different thicknesses, and automatically spraying the outer surface of the glass, the testing efficiency is improved.
[0023] 2. By having two sets of electric sliders move linearly along the corresponding electric slides, the carrier plate, two sets of clamping mechanisms, and the clamped insulating glass move, so that the insulating glass passes under the cooling nozzle at a constant speed and receives the cold air sprayed by the cooling nozzle, thus improving the accuracy of subsequent testing.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0027] Reference Figure 1-4 An auxiliary fixture for detecting dew point of insulating glass includes a base plate 1, a support frame 2 fixedly mounted on the top of the base plate 1, a cooling nozzle 3 fixedly mounted on the top of the support frame 2, a displacement mechanism 4 set on the top of the base plate 1, and two sets of clamping mechanisms 5 set above the displacement mechanism 4. The clamping mechanism 5 includes a lower clamping arm 501 and an upper clamping arm 502. A spring hinge 503 is installed at the connection between the lower clamping arm 501 and the upper clamping arm 502. A fixed shaft 7 is set in the middle of the spring hinge 503. Adjustment mechanisms 6 are connected to both ends of the fixed shaft 7. The lower clamping arm 501 and the upper clamping arm 502 are both hinged to the fixed shaft 7. A rubber layer 504 is fixedly installed on the clamping surface of the lower clamping arm 501 and the upper clamping arm 502. An extension frame 11 is fixedly mounted on the top of the support frame 2. An infrared thermal imager 12 is fixedly mounted on the bottom of the extension frame 11. A controller 13 is fixedly mounted on one side of the support frame 2. The controller 13 is electrically connected to the infrared thermal imager 12.
[0028] The insulating glass to be tested is placed above the displacement mechanism 4. The position of the clamping mechanism 5 is adjusted by the adjustment mechanism 6. Then, the upper clamping arm 502 is pressed, the lower clamping arm 501 is pressed against the lower edge of the glass, and the upper clamping arm 502 is pressed against the upper edge of the glass. The upper clamping arm 502 is released, and the elasticity of the spring hinge 503 causes the lower clamping arm 501 and the upper clamping arm 502 to automatically clamp the glass. The rubber layer 504 improves the protection effect of the glass during clamping. Then, the cooling nozzle 3 is connected to the external liquid nitrogen storage tank, and cold air is sprayed through the cooling nozzle 3 to simulate a low temperature environment. The displacement mechanism 4 drives the glass to move, so that different parts of the glass are evenly cooled. The glass is evenly sprayed with mist, and then the sealing performance of the glass is judged. The clamping mechanism 5 adapts to the edges of glass with different thicknesses, and at the same time automatically sprays the outer surface of the glass, which improves the detection efficiency. The displacement mechanism 4 drives the insulating glass clamped by the two sets of clamping mechanisms 5 to pass under the cooling nozzle 3 at a uniform speed and receive the cold air sprayed by the cooling nozzle 3. Then, the insulating glass continues to pass under the infrared thermal imager 12 at a uniform speed. The infrared thermal imager 12 is model FLIRE8Pro, which can penetrate the glass surface to reflect interference and directly display the temperature abnormal area caused by internal water vapor condensation, which improves the accuracy of glass dew point detection.
[0029] Reference Figure 1-3The displacement mechanism 4 includes two sets of electric slides 401, both sets of electric slides 401 are fixedly installed on the top of the base plate 1, the sliding end of the electric slides 401 is slidably connected to an electric slider 402, and the top of the two sets of electric sliders 402 is fixedly installed on a bearing plate 403; the adjustment mechanism 6 includes a support 601, the support 601 is fixedly installed on the top of the bearing plate 403, the top of the support 601 is fixedly installed with a motor base 602, the top of the motor base 602 is fixedly installed with a reciprocating motor 603, the two output ends of the reciprocating motor 603 are rotatably connected to the support 601 with screws 604, the outer surface of the screws 604 is threadedly connected with a movable block 605, one side of the movable block 605 is fixedly installed with an electric push rod 606, the telescopic end of the electric push rod 606 is fixedly installed with a connecting frame 607, and both ends of the fixed shaft 7 are fixedly installed with the connecting frame 607; Two sets of electric sliders 402 move linearly along the corresponding electric slides 401, thereby driving the support plate 403, the two sets of clamping mechanisms 5, and the clamped insulating glass to move. This achieves the purpose of the insulating glass passing under the cooling nozzle 3 at a uniform speed and receiving the cold air sprayed by the cooling nozzle 3, improving the accuracy of subsequent testing. When clamping glass of different sizes, the reciprocating motor 603 drives the two sets of screws 604 to rotate, causing the two sets of movable blocks 605 to move closer or further apart under the action of the threads. The position of the connecting frame 607 and the fixed shaft 7 can be further adjusted by extending and retracting the electric push rod 606, thereby adjusting the position of the two sets of clamping mechanisms 5. This is beneficial for adapting to insulating glass of different sizes and improves the applicability during use.
[0030] Reference Figure 2-4 Several sets of spring support plates 9 are installed on the top of the bearing plate 403 on one side of the support 601. The spring support plates 9 are equipped with telescopic guide rods. A guide groove 14 is opened at the bottom of the support 601. A guide block 15 is fixedly installed at the bottom of the movable block 605. The guide block 15 is slidably connected in the guide groove 14. The bottom surface of the glass is supported by several sets of spring support plates 9. When the glass is clamped by two sets of clamping mechanisms 5, the stability of the glass is further improved. When the movable block 605 moves, it drives the guide block 15 to slide in the guide groove 14. The movement of the movable block 605 is guided, which improves the stability when adjusting the distance between the two sets of clamping mechanisms 5.
[0031] Reference Figure 1-3Pressure sensors 10 are fixedly installed on the clamping surfaces of both the lower clamping arm 501 and the upper clamping arm 502. The pressure sensors 10 are located inside the rubber layer 504 and are electrically connected to the controller 13. Several sets of anti-slip racks 8 are fixedly connected to the opposite surfaces of the two sets of rubber layers 504. The pressure sensors 10 detect the force of the lower clamping arm 501 and the upper clamping arm 502 when clamping the glass and feed the pressure signal back to the controller 13 to avoid excessive clamping force that damages the glass or insufficient clamping force that causes the glass to loosen, thereby improving the safety and stability of the detection process. The several sets of anti-slip racks 8 further increase the friction between the rubber layer 504 and the insulating glass, further improving the stability when clamping the insulating glass.
[0032] Working principle: The insulating glass to be tested is placed above the displacement mechanism 4. The position of the clamping mechanism 5 is adjusted by the adjustment mechanism 6. Then, the upper clamping arm 502 is pressed, the lower clamping arm 501 is pressed against the lower edge of the glass, and the upper clamping arm 502 is pressed against the upper edge of the glass. The upper clamping arm 502 is released, and the elasticity of the spring hinge 503 causes the lower clamping arm 501 and the upper clamping arm 502 to automatically clamp the glass. The rubber layer 504 improves the protection effect during glass clamping. Then, the cooling nozzle 3 is connected to the external liquid nitrogen storage tank, and cold gas is sprayed through the cooling nozzle 3 to simulate a low-temperature environment. The displacement mechanism 4 drives the glass to move, so that different parts of the glass can be sprayed with mist evenly. Then the sealing performance of the glass is judged. The clamping mechanism 5 adapts to the edges of glass with different thicknesses and automatically sprays the outer surface of the glass, which improves the detection efficiency. The two sets of electric sliders 402 move linearly along the corresponding electric slides 401, thereby driving the support plate 403 and the two sets of clamping mechanisms 5 and the clamped insulating glass to move. This achieves the purpose of the insulating glass passing under the cooling nozzle 3 at a uniform speed and receiving the cold air sprayed by the cooling nozzle 3, which improves the accuracy of subsequent detection. The insulating glass unit, held by the displacement mechanism 4 and the two clamping mechanisms 5, passes uniformly under the cooling nozzle 3 and receives the cold air sprayed by the cooling nozzle 3. Then, it continues to pass uniformly under the infrared thermal imager 12. The infrared thermal imager 12 is a FLIRE8Pro model, which can penetrate the glass surface to reflect interference and directly display the temperature anomaly area caused by internal water vapor condensation, thus improving the accuracy of glass dew point detection. When clamping glass of different sizes, the reciprocating motor 603 drives the two sets of screws 604 to rotate, so that the two sets of movable blocks 605 move closer or further apart under the action of the screws. The position of the connecting frame 607 and the fixed shaft 7 can be further adjusted by the extension and retraction of the electric push rod 606, thereby adjusting the position of the two sets of clamping mechanisms 5. This is beneficial for adapting to insulating glass of different sizes and improving the applicability during use. Meanwhile, several sets of spring support plates 9 support the bottom surface of the glass, and two sets of clamping mechanisms 5 support the glass during clamping, further improving the stability of fixing the glass; the pressure sensor 10 detects the force of the lower clamping arm 501 and the upper clamping arm 502 when clamping the glass, and feeds the pressure signal back to the controller 13, so as to avoid the glass being damaged by excessive clamping force or the glass being loosened by insufficient clamping force, thus improving the safety and stability of the detection process; In addition, when the movable block 605 is displaced, it drives the guide block 15 to slide in the guide groove 14, which guides the movable block 605 during displacement and improves the stability when adjusting the distance between the two sets of clamping mechanisms 5; the friction between the rubber layer 504 and the insulating glass is further increased by several sets of anti-slip racks 8, which further improves the stability when clamping the insulating glass.
