Description

Technical Field

[0001] The present invention relates to the technical field of insulating glass production testing equipment, and particularly relates to a device for quickly testing the airtightness of insulating glass. Background Art

[0002] Insulating glass is made of two (or three) pieces of glass, using a high-strength and high-airtightness composite adhesive to bond the glass sheets to an aluminum alloy frame containing desiccant, resulting in a high-performance sound-insulating and heat-insulating glass. The multiple properties of insulating glass are superior to those of ordinary double-layer glass, so it has been recognized worldwide. Insulating glass is a glass product that separates two or more pieces of glass with effective supports evenly and bonds them hermetically around the perimeter, creating a dry gas space between the glass layers. Its main materials are glass, warm-edge spacer bars, corner bolts, butyl rubber, polysulfide glue, and desiccant.

[0018] 3. By setting the detection mechanism, the present invention can ensure the pressure balance of the insulating glass, preventing the uneven spraying of foam when leakage occurs due to inconsistent pressures in different regions inside the insulating glass. At some leakage points, the foam may spray out in a large amount and quickly because the pressure is low, but if the pressure in this area is high, the gas may not quickly leak through the seal strip, so the amount of foam sprayed is small or even may not spray out at all, improving the accuracy of the test.

Detailed Description of the Invention

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] A device for quickly testing the airtightness of insulating glass according to a preferred embodiment of the present invention will be elaborated in detail below.

[0023] Embodiment 1, as Figures 1 - 10 shown, includes a test bench 1, and a spraying mechanism 2 and a pressing mechanism 3 are arranged above the test bench 1; The spraying mechanism 2 includes a spraying ring 201 arranged above the test bench 1, the spraying ring 201 can rotate on the surface of the test bench 1, and a foam sprayer 202 is arranged above the spraying ring 201; The pressing mechanism 3 includes a test frame 301 arranged above the test bench 1. Inside the test frame 301, a first connecting piece 302 is provided. A rotating piece 303 is fixedly installed on the surface of the first connecting piece 302. Above the rotating piece 303, a second connecting piece 304 is provided. A first linkage 305 is arranged between the rotating piece 303 and the second connecting piece 304. The two ends of the first linkage 305 are respectively rotatably connected to the rotating piece 303 and the second connecting piece 304. At least four groups of the rotating piece 303 and the second connecting piece 304 are annularly arranged. A second linkage 306 is rotatably installed on the surface of the second connecting piece 304. A detection mechanism 4 is arranged at the bottom of the second linkage 306; The detection mechanism 4 is used to fit with the insulating glass and conduct detection; First, the staff places the insulating glass on the surface of the test bench 1. Subsequently, the test frame 301 is controlled to move downward until it fits with the surface of the insulating glass. The foam sprayer 202 is started to spray foam on the sealing strip on the side of the insulating glass. At the same time, the spraying ring 201 rotates, driving the foam sprayer 202 to rotate around the insulating glass, so that the foam is sprayed onto all parts of the sealing strip of the insulating glass. At this time, the staff controls the second connecting piece 304 inside the test frame 301 to move obliquely downward. When the second connecting piece 304 moves, it drives the rotating piece 303 and the first linkage 305 therebetween to rotate. At the same time, the second connecting piece 304 drives the detection mechanism 4 to expand and move outward through the second linkage 306, presenting a movement state of opening from the middle to the outside, and pressing the insulating glass. If there is a leak in the sealing strip inside the insulating glass, the air inside the insulating glass will leak from the leak point under the action of the pressing mechanism 3 and blow the foam to fly out. At this time, the staff can observe whether there is foam flying, and thus quickly test the sealing performance of the insulating glass; By arranging the foam sprayer 202, the foam liquid can be sprayed at the sealing strip on the side of the insulating glass. By cooperating with the pressing mechanism 3, the leak point of the sealing strip of the insulating glass can be better detected under the action of pressure. When there is a leak, the foam will expand at the leak point and quickly appear, helping the detection personnel quickly find the defect of the sealing strip. At the same time, the way that the pressing mechanism 3 applies pressure by spreading from the middle to the outside can avoid applying excessive local pressure on the edge of the glass or the sealing strip, preventing the glass from cracking or the sealing strip from deforming.

[0024] Embodiment 2, such as Figures 1 - 7As shown in the figure, sliding rods 307 are fixedly installed at the four corners of the top of the test frame 301. A sliding disk 308 is slidably installed on the surface of the sliding rods 307. Sliding grooves 309 are formed on the surface of the test frame 301. There are at least four groups of sliding grooves 309 arranged in a ring and located at the four corners of the test frame 301. A sliding block 310 is slidably installed on the surface of the second linkage 306 facing the sliding groove 309. A connecting seat 311 is slidably installed on the test frame 301 through the sliding groove 309. A linkage rod 312 is arranged between the connecting seat 311 and the sliding block 310. The two ends of the linkage rod 312 are respectively rotatably connected to the connecting seat 311 and the sliding block 310. A limiting rod 313 is fixedly installed on the surface of the connecting seat 311. The limiting rod 313 penetrates and extends into the inside of the sliding disk 308. A return spring 314 is sleeved on the surface of the sliding rod 307; When the sliding disk 308 moves downward, it will push the return spring 314 downward. Under the action of the return spring 314, the return spring 314 pushes the test frame 301 downward, so as to cover the surface of the insulating glass. As the sliding disk 308 continues to move downward, after the test frame 301 contacts the insulating glass and is restricted, the sliding disk 308 will drive the connecting seat 311 to slide in the sliding groove 309 on the surface of the test frame 301 through the limiting rod 313, and at the same time drive the connecting seat 311 to move downward. During the downward movement of the connecting seat 311, the sliding block 310 is pulled to incline outward through the linkage rod 312, and then the second linkage 306 is driven to move outward through the sliding block 310, so as to drive the pressing mechanism 3 to press the surface of the insulating glass; By providing the test frame 301, it can play a certain blocking role when the foam sprayer 202 sprays foam on the sealing strip on the side of the insulating glass, preventing the foam from being sprayed on the surface of the insulating glass during spraying, which may cause inconvenience for the staff to observe and require the staff to wipe it manually.

[0025] Example three, as Figures 1 - 10 As shown in the figure, the detection mechanism 4 includes detection blocks 401 arranged at the bottom of the second linkage 306. There are at least four groups of detection blocks 401 arranged in a ring. An electric telescopic rod 402 is fixedly installed at the top of the detection block 401. The second linkage 306 is rotatably connected to the electric telescopic rod 402. A pressure detector 403 is fixedly installed at the bottom of the detection block 401. The pressure detector 403 is electrically connected to the electric telescopic rod 402; When the detection mechanism 4 moves under the pressing mechanism 3, the detection block 401 first contacts the surface of the insulating glass. At this time, the pressure detector 403 at the bottom of the detection block 401 detects the pressure inside the insulating glass. If the pressure in some areas of the insulating glass is unbalanced, when the regional pressure is too small, the pressure detector 403 controls the electric telescopic rod 402 to extend, increasing the pressure on this area during pressing. If the regional pressure is too large, the pressure detector 403 controls the electric telescopic rod 402 to retract, reducing the pressure on this area during pressing, so as to ensure the pressure balance of the whole insulating glass during pressing; By setting the detection mechanism 4, the pressure balance of the insulating glass can be ensured, preventing the uneven spraying of foam when the pressure in different areas inside the insulating glass is inconsistent and leakage occurs. At some leakage points, due to the lower pressure, the amount of foam sprayed is large and rapid, but if the pressure in this area is higher, the gas may not leak quickly through the sealing strip, so the amount of foam sprayed is less, and even the situation where no foam is sprayed at all may occur, improving the accuracy of the test.

[0026] Example 4, as Figures 1 - 8 shown, a spraying box 203 is fixedly installed at the top of the spraying ring 201. A fixing rod 204 is fixedly installed on the inner wall of the spraying box 203. The foam sprayer 202 is slidably connected to the fixing rod 204. A connecting spring 205 is sleeved on the surface of the fixing rod 204. One end of the connecting spring 205 is fixedly connected to the foam sprayer 202. A placing plate 5 is fixedly installed at the top of the test bench 1. The placing plate 5 is located inside the spraying ring 201. An internal gear 6 is rotatably installed on the inner top of the test bench 1. The internal gear 6 penetrates and extends above the test bench 1 and is fixedly connected to the spraying ring 201. A connecting gear 7 is rotatably installed on the inner top of the test bench 1. The connecting gear 7 is meshed with the internal gear 6. A connecting frame 8 is fixedly installed on the inner top of the test bench 1. A driving motor 9 is fixedly installed on the surface of the connecting frame 8. The output end of the driving motor 9 is fixedly connected to the connecting gear 7; When the output end of the driving motor 9 drives the connecting gear 7 to rotate, the connecting gear 7 meshes with the internal gear 6 and drives the spraying ring 201 to rotate synchronously through the internal gear 6. At this time, the foam sprayer 202 will be driven to rotate around the insulating glass in a circular motion, evenly spraying the sealing strip on its side. At the same time, according to the fitting of the placing plate 5 and the test frame 301 to the surface of the insulating glass, it can prevent the foam from being sprayed on the glass surface. At the same time, when the spraying ring 201 rotates to the corner of the insulating glass, due to the limitation of the test frame 301 and the placing plate 5, the foam sprayer 202 can be pushed to slide on the surface of the fixing rod 204 and squeeze the connecting spring 205, causing the connecting spring 205 to contract due to elastic potential energy and then reset when the limitation is removed.

[0027] Example 5, as Figures 1 - 10As shown in the figure, a rubber soft pad 10 is fixedly installed at the bottom of the detection block 401, a support frame 11 is fixedly installed at the top of the test bench 1, a sliding frame 12 is arranged inside the support frame 11, two groups of sliding frames 12 are symmetrically arranged and are located on one side of the sliding disk 308. The sliding frame 12 is fixedly connected to the sliding disk 308, and the sliding frame 12 is slidably connected to the inner wall of the support frame 11. A driving cylinder 13 is fixedly installed on one side of the support frame 11. One side of the sliding frame 12 penetrates and extends to the outside of the support frame 11 and is fixedly connected to the output end of the driving cylinder 13; The driving cylinder 13 provided can drive the sliding disk 308 to move downward through the sliding frame 12, and then drive the pressing mechanism 3 to move, so as to press the insulating glass.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.
