Description

Technical Field

[0001] The present invention relates to the technical field of glass production, and particularly to an argon injection assembly, device and method for insulating glass. Background Art

[0002] Insulating glass is made of two pieces of glass, using a highly airtight composite adhesive as the insulating structure adhesive to bond the glass sheets to an aluminum alloy frame containing a desiccant. High-performance insulating glass uses low-emissivity glass and inert gas. Filling argon gas into insulating glass can effectively reduce the heat transfer coefficient U value of the glass system, which is a very economical and effective energy-saving measure and has been widely used in buildings. The methods of filling argon gas are divided into online argon gas filling and offline argon gas filling. Online argon gas filling is completed on the insulating glass production line, that is, before two or more glass sheets are completely bonded through a spacer frame and sealant, the inner cavity is filled with argon gas and then the sheets are combined, which is called online argon gas filling. Offline argon gas filling refers to the process of punching holes in the sealant and spacer frame of the completed insulating glass, connecting a pipeline to fill argon gas, which is called offline argon gas filling.

[0003] Online argon gas filling has a simple process and high automation, which is conducive to improving the continuity of production and processing, but is not conducive to improving production efficiency. The production time of each insulating glass is relatively prolonged on average. At the same time, this method needs to be completed in a closed space, which has certain limitations for special-shaped, extra-large and extra-long glass. Offline argon gas filling divides the production of insulating glass into two parts. Batch offline argon gas filling of semi-finished insulating glass reduces the processing time of the insulating glass production line and can effectively improve the production efficiency of insulating glass. In addition, offline argon gas filling is applicable to any insulating glass and is not affected by the size of the glass.

[0004] The existing argon gas injection technology for insulating glass is primitive. It mainly relies on an electric drill bit to first punch holes in the insulating structure adhesive, then punch holes in the aluminum alloy frame, and then form a channel between the outside and the glass interlayer space for argon gas injection. This method is likely to damage the aluminum alloy frame, resulting in the leakage of molecular sieve in the frame and causing the scrapping of glass products. This makes the production efficiency of insulating glass low, the overall yield low, and the product quality cannot be guaranteed. During the hole punching process, not only the aluminum alloy frame is damaged, but also the outer sealant is damaged. After the argon gas injection is completed, the inner aluminum frame needs to be sealed and the outer sealant needs to be filled, with frequent operations and low efficiency. Summary of the Invention

[0005] The object of the present invention is to provide a hollow glass argon injection assembly for solving the problems in the prior art that when argon is introduced into hollow glass, it is easy to damage the aluminum alloy frame and sealant, resulting in low production efficiency and unstable quality. By using this assembly, when forming an air injection passage, the damage to the sealant is small, and the distance extending into the aluminum alloy frame can be accurately controlled, thereby reducing the damage to the sealant and aluminum alloy frame, reducing the repair of the aluminum alloy frame and sealant after argon injection, improving the production efficiency, and ensuring the stable quality of the product.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] A hollow glass argon injection assembly, the hollow glass includes a glass sheet edge, a sealant layer, a frame outer layer, and a frame inner layer arranged in sequence from outside to inside; the injection assembly includes a first syringe and a second needle rod;

[0008] The first syringe is a tubular body with a first needle tip; a first blocking member is arranged in the middle of the outer side of the first syringe; when the first blocking member contacts the glass sheet edge, the first needle tip penetrates through the sealant layer and the frame outer layer, and there is a gap between the end of the first needle tip and the frame inner layer;

[0009] The second needle rod is a solid rod-shaped body and can penetrate into the first syringe from the rear end of the first syringe; a first fixing member is arranged at the rear end of the first syringe; a second fixing member is arranged at the rear end of the second needle rod;

[0010] After the second needle rod penetrates into the first syringe from the rear end of the first syringe, the second fixing member and the first fixing member cooperate to lock the relative positions of the first syringe and the second needle rod.

[0011] With the combined injection device of this solution, when forming an air injection channel during pipeline injection, only the external sealant layer and the frame outer layer are punctured, and no drilling and degumming are performed. Since the sealant belongs to a rubber-like material, this puncture action will not damage its physical properties. During the inflation process of the inflation pipeline, the first syringe will be squeezed by the sealant layer, making the device more stable during the inflation process. After the subsequent argon injection is completed, the sealant will physically heal, and no outer sealant filling is required or only a small amount of glue is needed for bonding. Compared with the traditional injection device, its production efficiency will be greatly improved. It will not damage the frame inner layer and avoid the leakage of the desiccant inside the frame.

[0012] As a preferred solution of the present invention, the second needle rod has a second needle tip, and the second needle tip can be covered by the first needle tip.

[0013] The second tip matches the first tip and is covered by the first tip. The second needle rod and the first needle tube form a cannula needle, and the solid second tip of the second needle tube coincides with the hollow tip of the first needle tube to form a needle with consistent physical and mechanical properties, which is beneficial to avoid sealant from entering the gap between the first needle tube and the second needle rod.

[0014] As a preferred solution of the present invention, the first fixing member is a cylindrical member, the front end of the cylindrical member is connected to the rear end of the first needle tube, and two opposite L-shaped openings are provided at the rear end of the cylinder; the second fixing member is two limiting rods relatively arranged at the rear end of the second needle rod; the two limiting rods are respectively adapted to the positions of the two L-shaped openings.

[0015] As a preferred solution of the present invention, the first fixing member is a tubular member with an external thread; the second fixing member is combined with the first fixing member through a fixing nut; the second fixing member is fixedly arranged outside the second needle rod; the fixing nut has an internal thread matching the external thread of the first fixing member, and the rear end of the fixing nut has a through hole.

[0016] The assembly of other components with the first needle tube is achieved by means of rotating snap or thread limit.

[0017] As a preferred solution of the present invention, the assembly further includes a third needle tube, the outer diameter of the third needle tube is smaller than the inner diameter of the first needle tube; a third fixing member is provided at the rear end of the third needle tube; after the third fixing member and the first fixing member are assembled, the front end of the third needle tube is located inside the first needle tube. After the first fixing member and the third fixing member are combined, they are used to limit the relative positions of the third needle tube and the first needle tube.

[0018] As a preferred solution of the present invention, a third limiting block is provided outside the third needle tube, and a sealing ring is provided on one side of the third limiting block away from the third fixing member. By providing the sealing ring, when the third needle tube is inflated, gas is prevented from escaping from the gap between the third needle tube and the first needle tube.

[0019] As a preferred solution of the present invention, the front end of the third needle tube is flat.

[0020] As a preferred solution of the present invention, the assembly further includes a fourth needle tube, the outer diameter of the fourth needle tube is smaller than the inner diameter of the first needle tube; after the fourth needle tube and the first needle tube are assembled, the front end of the fourth needle tube extends beyond the first tip of the first needle tube.

[0021] After the fourth needle tube and the first needle tube form a cannula needle, the needle of the fourth needle tube should be slightly longer than that of the first needle tube by several millimeters. This is beneficial for filling glue into the support frame and can prevent glue from entering the gap between the first needle tube and the fourth needle tube, avoiding blockage of the first needle tube and also preventing the glue from bonding the first needle tube and the fourth needle tube.

[0022] As a preferred embodiment of the present invention, the front end of the fourth syringe has a fourth needle tip.

[0023] A hollow glass argon injection device includes the above-mentioned hollow glass argon injection assembly.

[0024] A hollow glass argon injection device includes a perforating device, a gas supply device, and a glue injection device; the perforating device can be combined with the combination of the first syringe and the second needle rod, and the combination is inserted into the sealant layer and the outer layer of the frame, so that the front end of the combination is located within the support frame. The gas supply device includes an argon gas storage tank, a gas supply pipeline, and a control system. The argon gas storage tank is connected to the third syringe through the gas supply pipeline, and the control system is arranged on the gas supply pipeline for controlling the inflation switch and the argon gas flow rate. The glue injection device is connected to the fourth syringe for supplying glue to the fourth syringe.

[0025] The hollow glass argon injection device includes a plurality of hollow glass argon injection assemblies, so as to form a plurality of gas channels for use as a gas supply channel, an air outlet channel, and a detection channel respectively.

[0026] When inflating the same hollow glass, using multiple gas supply channels can improve the inflation efficiency. In addition, the injection device has a plurality of argon injection assemblies, which can simultaneously inflate a plurality of hollow glasses to improve the efficiency.

[0027] A method for injecting argon into hollow glass includes the following steps:

[0028] Use a syringe to penetrate the sealant layer of the hollow glass and the outer layer of the support frame of the frame, one end of the syringe is located within the support frame, and the other end of the syringe is located outside the hollow glass to form a gas channel;

[0029] Use the gas channel to fill the filling space of the hollow glass with argon;

[0030] After the argon filling is completed, use the gas channel to inject glue into the support frame to seal the through holes in the outer layer of the frame.

[0031] Furthermore, using the above-mentioned hollow glass argon injection assembly or the above-mentioned argon injection device to implement the argon injection method includes the following steps:

[0032] Combine the first syringe and the second needle rod; pass the front end of the combination of the first syringe and the second needle rod through the sealant layer and the outer layer of the frame, so that the first needle tip is located between the outer layer of the frame and the inner layer of the frame; remove the second needle rod, and the first syringe remains in the sealant layer to form a gas channel. The gas channel can be used as an air injection channel, an air outlet channel, or a detection channel.

[0033] Preferably, assemble the third syringe with the first syringe fixed in the sealant layer, inject argon into the filling space using the third syringe, and remove the third syringe after the injection is completed;

[0034] Preferably, assemble the fourth syringe with the first syringe fixed in the sealant layer, inject glue using the fourth syringe to seal the openings on the outer layer of the frame; remove the combination of the fourth syringe and the first syringe.

[0035] Preferably, when removing the combination of the fourth syringe and the first syringe, inject glue through the fourth syringe to facilitate the re-bonding of the sealant layer.

[0036] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0037] 1. For the argon intervention component of insulating glass in the present invention, by using the combination of the first syringe and the second needle rod, when forming an air injection channel through pipeline intervention, only the outer sealant layer and the outer layer of the frame are punctured, and no drilling and glue removal are performed. Since the sealant belongs to a rubber-like material, this puncture action will not damage its physical properties. During the inflation process of the gas filling pipeline, the first syringe will be squeezed by the sealant layer, making the device more stable during the inflation process. After the subsequent argon injection is completed, the sealant will physically heal, and no outer sealant filling is required or only a small amount of glue is needed for bonding. Compared with traditional intervention devices, its production efficiency will be greatly improved.

[0038] 2. For the argon intervention component of insulating glass in the present invention, by using the third syringe and the fourth syringe, and setting the third fixing member and the fourth fixing member matching the first syringe, the third syringe can be conveniently combined with the first syringe to achieve the inflation function, and the fourth syringe can be conveniently combined with the first syringe to achieve the function of injecting glue. The front end of the fourth syringe slightly extends beyond the first syringe to inject glue into the support frame, and it can avoid the glue entering the gap between the first syringe and the fourth syringe, preventing blockage of the first syringe and also preventing the glue from bonding the first syringe and the fourth syringe.

Detailed implementation mode

[0061] The present invention will be described in detail below with reference to the accompanying drawings.

[0062] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0063] Embodiment 1

[0064] A hollow glass argon injection assembly is used for hollow glass. The structure of the hollow glass is as Figure 1 shown. The first glass sheet 101 and the second glass sheet 102 clamp the aluminum alloy support frame 200 and are bonded on the outside of the support frame 200 through the sealant layer 300. The aluminum alloy support frame 200 is filled with a molecular sieve 201 for drying. Figure 2 It is a partial structure. From the outside to the inside of the hollow glass, that is, from Figure 2 the right side to the left side in

[0065] Figure 3 Figure 7 and Figure 7 shown, the components are, in sequence, the edge of the first glass sheet 101, the sealant layer 300, the outer layer 202 of the frame, the molecular sieve 201, the inner layer 203 of the frame, and the filling space 400. Figure 11As shown, when the first blocking member 13 contacts the edge of the glass sheet, the first needle tip 11 penetrates through the sealant layer 300 and the outer layer 202 of the frame. However, there is a gap between the end of the first needle tip 11 and the inner layer 203 of the frame, and the entire support frame 200 will not be penetrated. The above is only a schematic diagram of the relative position of the first syringe 1 and the insulating glass during use. Before inserting the first syringe 1 into the sealant, the second needle rod 2 should be inserted into the first syringe 1 first to prevent the sealant from entering the first syringe 1 and damaging the sealant layer 300. After the subsequent filling of argon is completed, it is beneficial for the re-bonding and sealing of the sealant layer 300.

[0066] Back to Figure 3 Or Figure 7 , a first fixing member 12 is provided at the rear end of the first syringe 1 (i.e., the end away from the first needle tip 11); the first fixing member 12 is used for fixedly connecting with the second needle rod 2. As Figure 4 And Figure 8 shown, the second needle rod 2 is a solid rod-shaped body, with a second needle tip 21 at the front end. The second needle tip 21 is slightly smaller than the first needle tip 11. The second needle tip 21 can be covered by the first needle tip 11. A second fixing member 22 is provided at the rear end of the second needle rod 2. After the second needle rod 2 is inserted into the first syringe 1 from the rear end of the first syringe 1, the second fixing member 22 and the first fixing member 12 cooperate to lock the relative positions of the first syringe 1 and the second needle rod 2.

[0067] More specifically, in this embodiment, the first fixing member 12 is a cylindrical member. The front end of the cylindrical member is connected to the rear end of the first syringe 1, and two opposite L-shaped openings are provided at the rear end of the cylinder; the second fixing member 22 is two limiting rods oppositely arranged at the rear end of the second needle rod 2; the two limiting rods are respectively adapted to the positions of the two L-shaped openings. After the limiting rods are inserted from the top of the L-shaped openings, they are fixed by rotation with the bottom ends of the L-shaped openings. To realize the fixation of the second needle rod 2 and the first syringe 1.

[0068] During use, first, the second needle rod 2 and the first syringe 1 are assembled. As Figure 12 shown, the outer diameter of the second needle rod 2 is slightly smaller than the inner diameter of the first syringe 1. After the first syringe 1 and the second needle rod 2 are assembled, there is basically no gap. A realized puncture needle is formed, which is beneficial to prevent the sealant from entering the gap between the first syringe 1 and the second needle rod 2. The second needle tip 21 is located inside the first needle tip 11. After the front end of the assembly of the first syringe 1 and the second needle rod 2 is located inside the support frame 200, the second needle rod 2 is separated from the first syringe 1 and taken out from the rear end of the first syringe 1 to obtain the structure as Figure 11 , and the first syringe 1 serves as an air injection channel.

[0069] Then, the third syringe 3 is assembled into the first syringe 1. The rear end of the third syringe 3 is connected to an argon gas cylinder through a supply pipe. A valve is provided on the supply pipe. As Figure 5 AndFigure 9 As shown, the third syringe 3 is a tubular body with flat ends at both ends; a third fixing member 32 is provided on the outside; the structure of the third fixing member 32 is the same as that of the second fixing member 22 and is also matched with the first fixing member 12. After the third fixing member 32 and the first fixing member 12 are assembled, they are used to limit the relative positions of the third syringe 3 and the first syringe 1. A third limiting block 31 is provided on the outside of the third syringe 3, and a sealing ring 33 is provided on the side of the third limiting block 31 away from the third fixing member 32. After the third fixing member 32 and the first fixing member 12 are assembled, as Figure 13 shown, the bottom of the third limiting block 31 and the first fixing member 12 squeeze the sealing ring 33 to achieve the sealing of the rear ends of the first syringe 1 and the third syringe 3.

[0070] As Figure 13 shown, the outer diameter of the third syringe 3 is smaller than the inner diameter of the first syringe 1, and the front end of the third syringe 3 is located inside the first syringe 1 and will not extend into the support frame 200. After the first syringe 1 and the third syringe 3 are assembled, argon is supplied through the rear end of the third syringe 3 to fill the filling space 400 with argon. Argon enters from the rear end of the third syringe 3, reaches the support frame 200, and then enters the filling space 400 through the drying holes 204 in the inner layer 203 of the frame. It should be noted that before filling, an air outlet channel should be provided on the side of the insulating glass opposite to the gas injection channel. The setting method of the air outlet channel is the same as that of the gas injection channel.

[0071] After injecting argon into the filling space 400 and the filling pressure is qualified, close the argon valve and separate the third syringe 3 from the first syringe 1.

[0072] Finally, use the fourth syringe 4 to inject glue to seal the openings of the outer layer 202 of the frame and the sealing glue layer 300. The structure of the fourth syringe 4 is as Figure 6 and Figure 10 shown, which is a tubular body with a fourth needle tip 41; a fourth fixing member 42 is provided at the rear end; the structure of the fourth fixing member 42 is the same as that of the second fixing member 22 and can cooperate with the first fixing member 12 to realize the relative fixation of the fourth syringe 4 and the second syringe. After assembling the fourth syringe 4 from the rear end of the first syringe 1 to the first syringe 1, as Figure 14 shown. The outer diameter of the fourth syringe 4 is slightly smaller than the inner diameter of the first syringe 1. The fourth needle tip 41 of the fourth syringe 4 slightly exceeds the first needle tip 11 of the first syringe 1. Connect the rear end of the fourth syringe 4 to the glue supply pipeline, inject a small amount of glue into the support frame 200, and then pull out the whole of the first syringe 1 and the second syringe. During the pulling process, continuously or intermittently inject a small amount of glue, and the sealing of the frame opening and the sealing of the sealing glue layer 300 can be achieved.

[0073] When using the combined intervention device tool of this solution, when forming an air injection channel through pipeline intervention, only the outer sealing glue layer 300 and the outer layer 202 of the frame are punctured, and no drilling and glue removal are performed. Since the sealing glue belongs to rubber materials, this puncture action will not damage its physical properties. During the inflation process of the air filling pipeline, the first syringe 1 will be extruded by the sealing glue layer 300, making the device more stable during the inflation process. After the subsequent argon injection is completed, the sealing glue will heal physically, and no outer sealing glue filling is required or only a small amount of glue is needed for bonding. Compared with traditional intervention devices, its production efficiency will be greatly improved.

[0074] The first syringe, the second needle rod, the third syringe and the fourth syringe are made of stainless steel, and the specific specifications are as follows:

[0075] The first syringe: outer diameter 2 - 10 mm, inner diameter 1.8 - 9.8 mm, length 5.5 - 50.5 mm; the length of the first needle tip is about 1 - 10 mm;

[0076] The second needle rod: outer diameter 2.3 - 9.7 mm, length 5 - 50 mm; the length of the second needle tip is about 1 - 10 mm;

[0077] The third syringe: outer diameter 2.3 - 9.7 mm, inner diameter 2.1 - 9.5 mm, length 5 - 50 mm;

[0078] The fourth syringe: outer diameter 2.3 - 9.7 mm, inner diameter 2.1 - 9.5 mm, length 5 - 50 mm; the length of the fourth needle tip is about 1 - 10 mm;

[0079] The usage method of the above hollow glass argon intervention component is summarized as follows.

[0080] 1. Combine the first syringe with the second needle rod; pass the front end of the combination of the first syringe and the second needle rod through the sealing glue layer and the outer layer of the frame, so that the first needle tip is located between the outer layer and the inner layer of the frame; remove the second needle rod to form an air injection channel;

[0081] 2. Assemble the third syringe with the first syringe fixed in the sealing glue layer, inject argon into the filling space by using the third syringe, and after the injection is completed, remove the third syringe;

[0082] 3. Assemble the fourth syringe with the first syringe fixed in the sealing glue layer, inject glue by using the fourth syringe to seal the opening of the outer layer of the frame; remove the combination of the fourth syringe and the first syringe.

[0083] Preferably, when removing the combination of the fourth syringe and the first syringe, inject glue through the fourth syringe. This is beneficial to the re - bonding of the sealing glue layer.

[0084] Example 2

[0085] The difference between this embodiment and Embodiment 1 is that, as Figure 15 shown, the first fixing member 12 is a tubular member with external threads; the second fixing member 22 is combined with the first fixing member 12 through a fixing nut 5; in the third syringe 3, the third limiting block 31 is directly used as the third fixing member 32, and the third fixing member 32 (the third limiting block 31) is combined with the first fixing member 12 through a fixing nut 5; the fourth fixing member 42 is combined with the first fixing member 12 through a fixing nut 5; the settings of the second fixing member 22, the third limiting block 31 (the third fixing member), and the fourth fixing member 42 are as Figure 16 , Figure 17 and Figure 18 shown. The cross-sectional structure of the fixing nut 5 is as Figure 19 shown. The fixing nut 5 has internal threads that match the external threads of the first fixing member 12. The rear end of the fixing nut 5 has a through hole, which is larger than the outer diameter of the second needle rod 2, larger than the outer diameter of the third syringe 3, and approximately the outer diameter of the fourth syringe 4. And it can block the second fixing member 22, the third limiting block 31, and the fourth fixing member 42.

[0086] Taking the cooperation between the second needle rod 2 and the first syringe 1 as an example, when the second needle rod 2 is combined with the first syringe 1, as Figure 20 shown. The end portions of the fixing nut 5 and the first fixing member 12 clamp the second limiting block to achieve the locking of the first syringe 1 and the second needle rod 2. The rear end of the second needle rod 2 passes through the through hole of the fixing nut 5.

[0087] Another difference from Embodiment 1 is that the front end of the second needle rod 2 is flat, and after being assembled with the first syringe 1, the front end of the second needle rod 2 is located inside the first syringe 1. The third syringe 3 can be used as the second needle rod 2 after blocking the pipeline through hole with glue. The fourth needle tip 41 of the fourth syringe 4 can be located inside the first syringe 1.

The gas supply device includes an argon gas storage tank, a gas supply pipeline, and a control system. The argon gas storage tank is connected to the third syringe through the gas supply pipeline, and the control system is arranged on the gas supply pipeline for controlling the inflation switch and the argon gas flow rate. The glue injection device is connected to the fourth syringe for supplying glue to the fourth syringe.

[0090] The hollow glass argon injection device includes a plurality of hollow glass argon injection components. To form a plurality of gas channels, which are respectively used as a gas supply channel, an air outlet channel, and a detection channel.

[0091] When inflating the same insulating glass, the use of multiple gas supply channels can improve the inflation efficiency. In addition, the intervention device has multiple argon intervention components, which can achieve simultaneous inflation of multiple insulating glasses to improve efficiency.

[0094] Use the gas channel to fill the filling space of the insulating glass with argon;

[0095] After the argon filling is completed, use the gas channel to inject glue into the support frame to seal the through holes in the outer layer of the frame.
