Description

Technical Field

[0001] The present invention relates to the field of insulating glass, and particularly to an insulating glass spacer frame group and a production method thereof. Background Art

[0002] Insulating glass is a glass product in which two or more pieces of glass are effectively and evenly supported and separated by a spacer, and are sealed by an adhesive method around the perimeter, so that a dry gas is formed between adjacent glasses. Insulating glass has the advantages of good heat insulation, sound insulation, beauty and practicality, and can reduce the self-weight and energy consumption of buildings. With the increasing global requirements for energy conservation and emission reduction, insulating glass is increasingly widely used in energy-saving buildings. The spacer is the core component of insulating glass. The spacer ensures that a fixed and appropriate distance is maintained between the double-layer or multi-layer glasses of insulating glass, and ensures that the gas in this distance remains dry to achieve the heat preservation effect of insulating glass.

[0003] The spacers of insulating glass are generally packaged in whole boxes in strip shape. The conventional length of the spacer is generally 5m / root. After opening the package, it cannot be directly used on insulating glass and needs to be processed through multiple processes before it can be used. The main processing methods of the current insulating glass spacers are as follows. First, the spacer is cut and bent. Calculate the perimeter of the insulating glass. If the perimeter is less than the length of a single spacer, it needs to be cut. If the perimeter is greater than the length of a single spacer, a section of spacer needs to be connected by a connector to meet the perimeter requirement. Because the perimeter specifications of insulating glass are diverse, it is very difficult to exactly match the cut-off surplus materials. Usually, it is used after being connected by a connector multiple times, which will increase the number of leakage points, and the sealing performance of the assembled insulating glass cannot be guaranteed, or many redundant spacers are discarded in order not to increase the leakage points. This method is mainly completed by manual and auxiliary equipment, and has a great impact on the stability of the insertion; the connectors are mainly divided into plastic connectors and steel connectors in terms of material. Plastic connectors are not resistant to aging and will soften at high temperatures; while steel connectors are difficult to insert at the joints and have high costs. Secondly, after the spacer is made into a square frame, molecular sieve is filled. The filling uses a filling machine to punch holes in the back of the spacer to inject the molecular sieve, and then the filling holes are sealed with glue. After the spacer is coated with glue, it is installed on the insulating glass. The molecular sieve has extremely strong moisture absorption ability. There may be a long time during the process from the spacer injected with the molecular sieve to the actual installation with the glass to form the finished insulating glass product. It is inevitable to come into contact with air and adsorb moisture in the air, resulting in a decrease in the adsorption ability, and in severe cases, the molecular sieve will fail, directly affecting the life of the insulating glass. The insertion of the connector inside the spacer will also affect the fluidity of the molecular sieve inside the spacer, reducing the filling efficiency. Due to the diverse specifications of insulating glass, it is difficult to implement automated processing for the filling process. At present, it still needs to be completed by manual and auxiliary equipment, with unstable quality and high labor intensity. Summary of the Invention

[0026] Check the total perimeter of the spacer frame formed by the fixed length specification of the sealed spacer and the fixed length specification of the space spacer, so that it is greater than or equal to the total perimeter L of the initially set spacer frame minus the free adjustment activity value c of the total length of the spacer frame and less than or equal to the total perimeter L of the initially set spacer frame plus the free adjustment activity value c of the total length of the spacer frame; if the check fails, readjust the dimension of the spacer frame from the edge of the insulating glass to determine the new total perimeter L of the initially set spacer frame or re-determine the fixed length specification of the space spacer.

[0027] Preferably, it further comprises the following steps:

[0028] Screen the space spacers in the cutting leftovers in the inventory according to the fixed length specification of the space spacer, and directly select and use them if there are any that can match; if none of the space spacers in the cutting leftovers in the inventory can match, cut the space spacers in the inventory according to the fixed length specification of the space spacer to obtain space spacers with the fixed length specification.

[0034] The technical solution of the present invention has the following remarkable beneficial effects:

[0035] 1. In this application, by analyzing the specifications of the processed insulating glass, the fixed length specifications of the sealed spacer bars filled with desiccant and the spacer bars without desiccant can be obtained, so as to obtain an optimized matching scheme. After bending the sealed spacer bars and / or spacer bars, a spacer bar group frame is formed by plugging. The whole process is convenient and flexible, which can effectively make full use of the surplus materials of the spacer bar 200, or minimize or eliminate the unusable part after cutting the whole spacer bar, thus saving production costs. At the same time, the plug-in parts used in the traditional process can be omitted, which can also reduce production costs and labor intensity.

[0036] 2. This application has the characteristics of high flexibility and can be applied to the processing of insulating glass with various size specifications. For the sealed spacer bar with self-sealing desiccant, the process of filling desiccant during the formation of insulating glass is omitted, avoiding the pollution of the glass by desiccant dust, reducing the exposure time of the desiccant to the air before the insulating glass is assembled, and effectively improving the processing quality and service life of the insulating glass.

[0037] 3. Both the sealed spacer bar and the spacer bar in this application can be processed by automated production, and the plug-in connection between the two to form a spacer bar group frame can also be directly completed by automated machinery, without the need for manual participation, so that high-intensity and repetitive manual labor can be liberated, and automated production can also greatly improve production efficiency and product quality.

[0054] In order to effectively reduce production costs and improve production efficiency, a hollow glass spacer frame group and its production method are proposed in this application. Among them, Figure 1This is a schematic structural diagram of the insulating glass spacer frame group in the first embodiment of the present invention. Figure 2 This is a schematic structural diagram of the insulating glass spacer frame group in the second embodiment of the present invention. As Figure 1 and Figure 2 shown, the insulating glass spacer frame group may include a sealed spacer 100 and a space spacer 200. The sealed spacer 100 has a hollow accommodation cavity inside, and a desiccant 1003 is filled in the accommodation cavity. The sealed spacer 100 has opposite first and second ends, and the first and second ends of the sealed spacer 100 are in a closed state, and both the first and second ends have insertion structures 1002; the space spacer 200 has opposite third and fourth ends, and both the third and fourth ends of the space spacer 200 are open; the first end is inserted into the third end, and the second end is inserted into the fourth end, and then bent to form a spacer frame group.

[0055] As Figure 1 shown, the sealed spacer 100 can be bent multiple times, and the space spacer 200 can also be bent at least once. The bent sealed spacer 100 and the bent space spacer 200 are inserted. That is, the insertion structure 1002 at the first end of the sealed spacer 100 is inserted into the third end of the space spacer 200, and the insertion structure 1002 at the second end of the sealed spacer 100 is inserted into the fourth end of the space spacer 200, thereby bending to form a spacer frame group. Generally speaking, the spacer frame group is rectangular or square. Of course, in other special cases, the spacer frame group can also be any polygon, an irregular figure with an arc, etc., and no restrictions are imposed on it in this application.

[0056] As Figure 2 shown, the sealed spacer 100 can be bent multiple times, and the space spacer 200 can be straight without bending. The bent sealed spacer 100 and the straight space spacer 200 are inserted.

[0057] In a feasible embodiment, Figure 3 This is a schematic structural diagram of the sealed spacer in the first embodiment of the present invention. Figure 4 This is a schematic diagram of the insertion of the sealed spacer in the first embodiment of the present invention and the space spacer. As Figure 3 and Figure 4As shown, the first end and the second end of the sealed spacer 100 are in a closed state. The sealed spacer 100 has a hollow accommodation cavity inside, and a desiccant 1003 is filled in the accommodation cavity. The ends of the first end and the second end of the sealed spacer 100 both have step portions 19 in the circumferential direction. The space spacer 200 has a hollow accommodation cavity inside, and the third end and the fourth end of the space spacer 200 are in an open state, so that the openings at the ends of the space spacer 200 can be inserted into the ends of the sealed spacer 100, and the ends of the space spacer 200 abut against the step portions 19 of the sealed spacer 100.

[0058] As Figure 3 and Figure 4 shown, the sealed spacer 100 can be in a long strip shape or any other shape with a bent structure to adapt to the shape of the insulating glass. The sealed spacer 100 can be in a tubular shape. Therefore, the sealed spacer 100 has a hollow accommodation cavity inside, and a desiccant 1003 is filled in the accommodation cavity. The desiccant 1003 is used to absorb the water vapor in the closed annular region surrounded by the spacer, so as to keep this region dry and thus improve the heat insulation performance.

[0059] In order to seal the desiccant 1003 in the accommodation cavity to prevent its leakage and also avoid its absorption of moisture in the external air through the ends of the sealed spacer 100, as Figure 3 and Figure 4 shown, the two ends of the sealed spacer 100 need to be in a closed state. Generally speaking, the cross-section of the sealed spacer 100 can be generally rectangular. Correspondingly, the cross-section of the space spacer 200 can also be generally rectangular. In this way, at least two corresponding faces of the sealed spacer 100 and the space spacer 200 are in a parallel state, and these two faces can be respectively in close contact with the adjacent glasses, so as to achieve the seal between the spacer and the glass.

[0060] As Figure 3 and Figure 4As shown, both ends of the sealed spacer 100 have stepped portions 19 in the circumferential direction. The stepped portions 19 are located around the ends of the sealed spacer 100, which can reduce the size of the ends of the sealed spacer 100 in the radial direction. The internal space of the spacer 200 has a hollow accommodation cavity, and both ends of the spacer 200 are open. The profile of the spacer 200 is the same as that of the sealed spacer 100, that is: at non-end portions, the cross-section of the sealed spacer 100 in the radial direction is the same as the cross-section of the spacer 200 in the radial direction. Therefore, the spacer 200 can also be in a long strip shape or in any other shape with a curved structure to adapt to the shape of the insulating glass. The spacer 200 is similar to the sealed spacer 100 and can also be tubular. After that, the openings at the ends of the spacer 200 can be inserted into the ends of the sealed spacer 100, and the ends of the spacer 200 abut against the stepped portions 19 of the sealed spacer 100.

[0061] As Figure 3 and Figure 4 shown, further, the distance by which the stepped portion 19 at the end of the sealed spacer 100 is reduced in the radial direction of the sealed spacer 100 is equal to the wall thickness of the spacer 200. In this way, the sealed spacer 100 reduced in the radial direction can clamp the inner wall of the end of the spacer 200, further improving the firmness of the insertion between the two. Secondly, the outer side wall of the sealed spacer 100 and the outer side wall of the spacer 200 can remain flat and in a straight line, greatly improving the aesthetic degree after the sealed spacer 100 and the spacer 200 are inserted.

[0062] Further, as Figure 3 and Figure 4 shown, the sealed spacer 100 has opposite third side wall 13 and fourth side wall 14. At the end of the sealed spacer 100, the third side wall 13 has a first guiding portion 112 inclined towards the center of the sealed spacer 100, and the fourth side wall 14 has a second guiding portion 122 inclined towards the center of the sealed spacer 100. The third side wall 13 and the fourth side wall 14 are the side walls that do not closely adhere to the glass when forming the insulating glass. The presence of the first guiding portion 112 and the second guiding portion 122 can make the end of the sealed spacer 100 easily inserted into the spacer 200. The guiding structure of the above-mentioned sealed spacer 100 can be formed by mechanical extrusion or pressing.

[0063] As Figure 3 and Figure 4As shown, the end of the first guiding portion 112 abuts against the end of the second guiding portion 122 to achieve sealing. Specifically, the end of the first guiding portion 112 away from the step portion 19 gradually abuts against the end of the second guiding portion 122 away from the step portion 19, thereby achieving sealing of the end. The abutting portion extends parallel for a certain length, and the parallel section can be tightly bonded by welding or sealed with a sealing material together, thereby further improving the sealing performance and avoiding local leakage.

[0064] As a feasible solution, as Figure 3 and Figure 4 shown, before being processed into insulating glass, no through hole 1001 needs to be provided on the side wall of the encapsulated spacer 100 in the insulating glass spacer frame. Compared with the traditional grooved aluminum insulating glass spacer, when processing insulating glass, it is necessary to fill the desiccant 1003 into the grooved aluminum insulating glass spacer at the insulating glass production site. During the filling process of the desiccant 1003, the broken powder of the desiccant 1003 is likely to leak and contaminate the glass, and the desiccant 1003 is exposed to the air for too long before the glass is assembled. The water absorption of the desiccant 1003 will cause a significant reduction in the drying effect. Therefore, in the insulating glass spacer frame of the present application, the encapsulated spacer 100 directly fills the desiccant 1003 in the spacer and seals it. At the same time, no through hole 1001, that is, no adsorption hole, is provided on the side wall of the encapsulated spacer 100, thus avoiding the problem that the desiccant 1003 absorbs moisture in the outside air and the drying effect is reduced when the encapsulated spacer 100 is not installed in the insulating glass. When the encapsulated spacer 100 in the present application is installed in the insulating glass, a through hole 1001 is directly formed on the side wall of the encapsulated spacer 100 by using an opening device. Since the current opening devices are becoming more and more advanced, for example, a laser opening device can be used to directly and efficiently form a through hole 1001 on the side wall of the encapsulated spacer 100 at the installation site of the spacer and the insulating glass. The through hole 1001 is generally formed in the closed area formed by the spacer facing the insulating glass spacer according to specific requirements. The installation efficiency can be greatly improved by the laser opening method; of course, the through hole 1001 can also be formed by stamping or punching.

[0065] The insulating glass spacer assembly frame in the present application comprises a sealing spacer 100 and a spacer 200. The end of the sealing spacer 100 has a step portion 19, so that it can be inserted into the open end of the spacer 200. The end of the spacer 200 abuts against the step portion 19 of the sealing spacer 100, thereby achieving the plugging of the opening at the end of the spacer 200 with the end of the sealing spacer 100. In the above manner, the spacer in the insulating glass can form a closed ring only by the spacer itself without using other parts, thereby ensuring that the gas in the ring remains dry.

[0066] The sealing type spacer 100 in the above-mentioned embodiment does not need to be cut during use, and a single sealing type spacer 100 can be continuously bent into a frame, and then directly plugged into the spacer 200 to form a closed insulating glass spacer assembly frame. The length of the spacer 200 can be cut at will, so the length of the insulating glass spacer assembly frame can meet various needs. The process of this application is simple, eliminates the use of connectors, reduces costs, and improves product quality and production efficiency. The sealing type spacer 100 has the advantages of high reliability, environmental protection, neatness, and convenience for insulating glass processing. The sealing type spacer 100 has no prefabricated through hole 1001 when it is mass-produced in the factory, so that the desiccant 1003 can be avoided from being exposed to the air to absorb water, eliminating the need for additional sealed packaging, and the structure is simpler and more reliable.

[0067] In another possible implementation, Figure 5 This is a schematic diagram of the three-dimensional structure of the sealed spacer in the second embodiment of the present invention. Figure 6 This is a partial exploded view of the sealed spacer bar and the spacer bar in the second implementation mode in the embodiment of the present invention. Figure 7 This is a partial schematic diagram of the end of the sealed spacer bar after being plugged into the spacer bar in the second implementation mode in the embodiment of the present invention. Figure 8 FIG. 1 is a partial internal schematic diagram of the sealing spacer bar after being plugged into the end of the spacer bar in the second implementation mode of the embodiment of the present invention. Figures 5 to 8 As shown, the plug-in structure 1002 at the first end and the second end of the sealing spacer strip 100 may include: a main body with an axis, which has a first side wall 11 and a second side wall 12 opposite to each other, and a third side wall 13 and a fourth side wall 14 opposite to each other, and the first side wall 11, the second side wall 12, the third side wall 13 and the fourth side wall 14 form a accommodating cavity; at at least one end of the main body, the third side wall 13 and the fourth side wall 14 are pressed in a direction perpendicular to the third side wall 13 to form a sheet structure 15, and the sheet structure 15 is located at both ends of the first side wall 11 and the second side wall 12, and is respectively rolled around the axis to form a curved shape.

[0068] likeFigure 5 As shown, the body can be made of metal materials, such as aluminum, copper, etc. with relatively high toughness. The body can at least include opposite first side walls 11 and second side walls 12, and opposite third side walls 13 and fourth side walls 14. The first side walls 11, second side walls 12, third side walls 13 and fourth side walls 14 form a receiving cavity. When the insulating glass spacer is arranged in the insulating glass, the first side walls 11 and second side walls 12 are respectively in close contact with the side surfaces of adjacent glasses in the insulating glass.

[0069] As Figure 5 shown, the first side walls 11 and second side walls 12 can be planar, so that they can better fit with the side surfaces of adjacent glasses in the insulating glass, thus forming a sealed state. The third side walls 13 and fourth side walls 14 can be planar, can also be slightly curved arc surfaces, or can be wavy curved surfaces, etc. As long as the degree of bending of the third side walls 13 and fourth side walls 14 is not large, there is no limitation on them in this application.

[0070] As Figure 5 shown, the upper ends of the first side walls 11 and second side walls 12 are connected to the third side walls 13, and the lower ends of the first side walls 11 and second side walls 12 are connected to the fourth side walls 14, thus forming a receiving cavity.

[0071] As a feasible solution, a first bending portion 17 recessed into the receiving cavity can be provided at the connection between the first side wall 11 and the third side wall 13, that is, a first bending portion 17 recessed into the receiving cavity can be provided at the corner of the body. The existence of the first bending portion 17 can effectively improve the strength of the entire body. The first bending portion 17 can include a first folded edge and a second folded edge. The first folded edge can be parallel to the fourth side wall 14 and is connected to the upper end of the first side wall 11. The second folded edge has a certain angle with the first side wall 11, and the second folded edge is respectively connected to the first folded edge and the third side wall 13.

[0072] As a feasible solution, as Figure 5 shown, a second bending portion 18 recessed into the receiving cavity can be provided at the connection between the second side wall 12 and the third side wall 13, that is, a second bending portion 18 recessed into the receiving cavity can be provided at the corner of the body. The existence of the second bending portion 18 can effectively improve the strength of the entire body. The second bending portion 18 can include a third folded edge and a fourth folded edge. The third folded edge can be parallel to the fourth side wall 14 and is connected to the upper end of the second side wall 12. The fourth folded edge has a certain angle with the second side wall 12, and the fourth folded edge is respectively connected to the third folded edge and the third side wall 13.

[0073] As Figure 5As shown, the structure at the non-end part of the entire body can be the same as the cross-section of the current conventional spacer. Therefore, the filled spacer 100 in this application can be directly processed from the current conventional spacer.

[0074] As Figure 5 shown, at at least one end of the body, the third side wall 13 and the fourth side wall 14 are pressed in a direction perpendicular to the third side wall 13 to form a sheet-like structure 15. In the above structure, the third side wall 13 and the fourth side wall 14 can be pressed to form the sheet-like structure 15 by mechanical extrusion. For example, the third side wall 13 can be inclined and extruded towards the fourth side wall 14, and the fourth side wall 14 basically does not move. Eventually, the third side wall 13 and the fourth side wall 14 are fitted together to form the sheet-like structure 15; the third side wall 13 can also be inclined and extruded towards the fourth side wall 14, and the fourth side wall 14 is also inclined and extruded towards the third side wall 13, so that the position where the third side wall 13 is fitted to the fourth side wall 14 to form the sheet-like structure 15 is lower than the height of the third side wall 13 at the non-end part and higher than the height of the fourth side wall 14 at the non-end part, so as to ensure the flatness of the side walls when inserting other spacers without further adjusting the position of the sheet-like structure 15 in the height direction in the later stage. As a feasible option, the position where the third side wall 13 is fitted to the fourth side wall 14 to form the sheet-like structure 15 is much lower than the height of the third side wall 13 at the non-end part and slightly higher than the height of the fourth side wall 14 at the non-end part, which is convenient for later winding of the sheet-like structure 15. After being wound into a curved shape, it can be inserted into other spacers.

[0075] During the process of forming the sheet-like structure 15 above, the first side wall 11 is bent outwards with its longitudinal midline as the symmetry center, so that the inner wall of the part of the first side wall 11 below the midline is in close contact with the inner wall of the part of the first side wall 11 above the midline; the second side wall 12 is bent outwards with its longitudinal midline as the symmetry center, so that the inner wall of the part of the second side wall 12 below the midline is in close contact with the inner wall of the part of the second side wall 12 above the midline. Through the above, the first side wall 11 and the second side wall 12 can also be pressed into the sheet-like structure 15 together. At the same time, the thickness of the sheet-like structure 15 will not be increased, which is beneficial for the two ends of the sheet-like structure 15 to be wound into a curved shape around the axis later. Of course, since the first side wall 11 and the second side wall 12 are bent correspondingly, the width of the sheet-like structure 15 will also be further increased. However, winding the two ends of the sheet-like structure 15 in the directions of the first side wall 11 and the second side wall 12 into a curved shape around the axis can reduce the width of the sheet-like structure 15, so that the sheet-like structure 15 can be inserted into other spacers.

[0076] As feasible, the sheet-like structure 15 can be in a sealed state at one end of the body with the sheet-like structure 15. In a specific embodiment, the end face of the sheet-like structure 15 can be sealed by welding, that is, the end faces of the third side wall 13 and the fourth side wall 14 are welded, the end face of the bent first side wall 11 is welded, and the end face of the bent second side wall 12 is welded, finally achieving complete sealing at the end face of the sheet-like structure 15. It can also be understood that the flattened portion of the sheet-like structure 15 can be sealed by welding, that is, after bending, the first side wall 11, the second side wall 12, the third side wall 13, and the fourth side wall 14 are flattened into a sheet-like structure 15 with the inner walls closely attached, and complete sealing of the sheet-like structure 15 is achieved by welding the flattened portion. In another specific embodiment, an adhesive is provided on the inner side wall of the sheet-like structure 15 to seal one end of the body with the sheet-like structure 15. When the first side wall 11, the second side wall 12, the third side wall 13, and the fourth side wall 14 are pressed into the sheet-like structure 15, the adhesive can bond the inner side walls of the third side wall 13 and the fourth side wall 14, the inner side wall of the bent first side wall 11, and the inner side wall of the bent second side wall 12, finally achieving complete sealing at the end face of the sheet-like structure 15. Through the above method, the sealing of the end of the insulating glass spacer can be achieved. If a desiccant 1003 is filled in the accommodation cavity inside the insulating glass spacer, the sealing degree of the desiccant 1003 can be ensured, and it can be prevented from being affected by moisture or scattered when not in use.

[0077] As Figure 5 shown, both ends of the sheet-like structure 15 in the directions of the first side wall 11 and the second side wall 12 are wound around the axis into a curved shape, so that the end of the insulating glass spacer can be inserted into other spacers. As feasible, the degree to which both ends of the sheet-like structure 15 in the directions of the first side wall 11 and the second side wall 12 are wound around the axis into a curved shape needs to meet the following conditions: If the third side wall 13 and the fourth side wall 14 are in a parallel state at a non-end portion, then the maximum distance of the contour of the sheet-like structure 15 in a curved shape at the end in the direction perpendicular to the third side wall 13 is less than the distance between the inner side walls of the third side wall 13 and the fourth side wall 14 of the body at the non-end portion; If the first side wall 11 and the second side wall 12 are in a parallel state at a non-end portion, then the maximum distance of the contour of the sheet-like structure 15 in a curved shape at the end in the direction perpendicular to the first side wall 11 is less than the distance between the inner side walls of the first side wall 11 and the second side wall 12 of the body at the non-end portion.

[0078] As Figure 5As shown and as feasible, the body has a tapered section 16 near the sheet-like structure 15. The tapered section 16 is located between the sheet-like structure 15 and the body with normal thickness that is not pressed. At the tapered section 16, the third side wall 13 gradually inclines towards the fourth side wall 14 until the third side wall 13 abuts against the fourth side wall 14. The abutting portion of the third side wall 13 and the fourth side wall 14 is in a straight line perpendicular to the third side wall 13. Through the tapered section 16, the body with normal thickness that is not pressed is thus transitioned to the sheet-like structure 15.

[0079] As Figure 5 shown and as feasible, at the tapered section 16, a first groove 111 is recessed from the first side wall 11 into the accommodation cavity of the body. The first groove 111 extends along the axial direction and extends to the abutting portion of the third side wall 13 and the fourth side wall 14. Similarly, at the tapered section 16, a second groove 121 is recessed from the second side wall 12 into the accommodation cavity of the body. The second groove 121 extends along the axial direction and extends to the abutting portion of the third side wall 13 and the fourth side wall 14. Since the third side wall 13 gradually inclines towards the fourth side wall 14 until the third side wall 13 abuts against the fourth side wall 14, therefore, the thicknesses of the first side wall 11 and the second side wall 12 in the vertical direction also need to gradually decrease accordingly. When there are the first groove 111 and the second groove 121, the portions of the first side wall 11 and the second side wall 12 with reduced thickness can be accommodated by the first groove 111 and the second groove 121 that are recessed into the accommodation cavity. In this way, at the tapered section 16, the first side wall 11 and the second side wall 12 will not be overly extended and protruded outward due to the extrusion of the third side wall 13 gradually inclining towards the fourth side wall 14, thus avoiding an increase in the size of the body in the direction perpendicular to the first side wall 11 and making it impossible to be inserted into other spacer bars.

[0080] Furthermore, as Figure 1 shown, the distance between the two opposite side walls of the first groove 111 gradually decreases in the direction close to the abutting portion of the third side wall 13 and the fourth side wall 14 until they fit together. The distance between the two opposite side walls of the second groove 121 gradually decreases in the direction close to the abutting portion of the third side wall 13 and the fourth side wall 14 until they fit together. By the above method, it is ensured that throughout the tapered section 16, the first side wall 11 and the second side wall 12 in the area up to the sheet-like structure 15 will not be overly extended and protruded outward due to the extrusion of the third side wall 13 gradually inclining towards the fourth side wall 14. At the sheet-like structure 15, it is bent by winding around the axis at both ends in the direction of the first side wall 11 and the second side wall 12 respectively to reduce the size in the direction perpendicular to the first side wall 11.

[0081] Due to the presence of the tapered section 16, after the insulating glass spacer is inserted into other spacers, the outer sidewall of the tapered section 16 can be engaged with the inner wall side of the end of the other spacer, so that the two can be connected together and are not easily separated.

[0082] As Figures 6 to 8 shown, the end of the sheet-like structure 15 of the encapsulated spacer 100 can be inserted into the end of the spacer 200. Further, the cross-section of the spacer 200 in the radial direction can be the same as the cross-section structure of the encapsulated spacer 100 at the non-end part in the radial direction. In this way, when the end of the sheet-like structure 15 of the encapsulated spacer 100 is inserted into the end of the spacer 200, each sidewall of the encapsulated spacer 100 and each corresponding sidewall of the spacer 200 can be located on the same plane. It can not only ensure that the entire spacer frame can be fitted with the glass after being installed in the insulating glass, ensuring the sealing performance, but also improve the aesthetics of the spacer frame. In the production process of the encapsulated spacer 100 in this application, the desiccant 1003 can be filled first and then the sheet-like structure 15 can be formed at the end, and no holes are made in the sidewall of the body 1 during the production process. When the entire spacer frame is installed in the insulating glass, holes are made in the sidewall of the body, so as to avoid the desiccant 1003 in the insulating glass spacer being exposed to the air for a long time, resulting in a decrease in the adsorption capacity.

[0083] In the above embodiment, the encapsulated spacer 100 can be directly formed by flattening the end of a traditional spacer with a generally rectangular cross-section and then winding it. The whole processing process is convenient and fast, and high-efficiency batch production can be carried out. After the above-mentioned encapsulated spacer 100 is processed, the contour of the bent end of the body of the encapsulated spacer 100 can be made smaller than the contour size of the adjacent traditional spacer, so that the end of the encapsulated spacer 100 can be directly inserted into the adjacent traditional spacer 200, thereby realizing the mutual plug-in of the spacers. During the process of the whole spacer being plugged in, no other plug-in parts for connecting the spacers need to be introduced, effectively reducing the types of spare parts required for installing the insulating glass.

[0084] In the above embodiment, the encapsulated spacer 100 can be formed by the following processing method: As Figure 5As shown, the first side wall 11 of the body is pressed towards the accommodation cavity of the body to form a concave first groove 111, and the second side wall 12 of the body is pressed towards the accommodation cavity of the body to form a concave second groove 121. The first groove 111 and the second groove 121 are located at the tapered section 16, that is, the first groove 111 and the second groove 121 are at a certain distance from the end face of the body, and the length of this distance is the length of the sheet-like structure 15. By pre-processing the first groove 111 and the second groove 121, it can be avoided that the first side wall 11 and the second side wall 12 bulge outwards excessively due to the extrusion of the third side wall 13 gradually tilting towards the fourth side wall 14 in the later stage. As Figure 5 shown, the third side wall 13 of the body is pressed down towards the fourth side wall 14, so that the third side wall 13 gradually tilts towards the fourth side wall 14 until the third side wall 13 abuts against the fourth side wall 14, thereby forming a tapered section 16. In the above steps, the fourth side wall 14 can also be pressed down towards the third side wall 13, so that the fourth side wall 14 also gradually tilts towards the third side wall 13. The degree of the fourth side wall 14 tilting towards the third side wall 13 is much smaller than the degree of the third side wall 13 gradually tilting towards the fourth side wall 14, so that the position where the third side wall 13 abuts against the fourth side wall 14 is lower than the height of the third side wall 13 at the non-end part and slightly higher than the height of the fourth side wall 14 at the non-end part, thereby ensuring that there is enough space for winding the sheet-like structure 15 later, and it can be inserted into other spacer bars after being wound into a curved shape. As Figure 5 shown, the third side wall 13 and the fourth side wall 14 at the end of the body are flattened in a direction perpendicular to the third side wall 13 to form a sheet-like structure 15 in a planar shape. In the above steps, the third side wall 13 and the fourth side wall 14 in the area near the end of the tapered section 16 are flattened in a direction perpendicular to the third side wall 13 to form a sheet-like structure 15 in a planar shape. Before the flattening process, the first side wall 11 in the above area can be bent outwards along its midline first, so that the inner wall of the part of the first side wall 11 below the midline is close to the inner wall of the part of the first side wall 11 above the midline during the flattening process. Before the flattening process, the second side wall 12 can be bent outwards along its midline first, so that the inner wall of the part of the second side wall 12 below the midline is close to the inner wall of the part of the second side wall 12 above the midline during the flattening process. In the above steps, if the sheet-like structure 15 needs to be sealed, before flattening to form the sheet-like structure 15, a small amount of adhesive can be filled inside the end of the body first, and after the end of the body is flattened, the adhesive diffuses to seal the inside of the sheet-like structure 15. Or after the sheet-like structure 15 is formed, the end face of the sheet-like structure 15 (i.e., the flattened part) is sealed by welding. As Figure 5As shown, both ends of the sheet-like structure 15 in the directions of the first side wall 11 and the second side wall 12 are wound into a curved shape around the axis. In this step, the two ends of the sheet-like structure 15 in the directions of the first side wall 11 and the second side wall 12 can be clamped respectively by a mechanical automation device and then wound around the axis of the body, so that the two ends of the sheet-like structure 15 become curved. In this way, the maximum distance of the contour of the curved sheet-like structure 15 in the direction perpendicular to the first side wall 11 is less than the distance between the inner side walls of the first side wall 11 and the second side wall 12 of the body at non-end portions, and the maximum distance of the contour of the curved sheet-like structure 15 in the direction perpendicular to the third side wall 13 is less than the distance between the inner side walls of the third side wall 13 and the fourth side wall 14 of the body at non-end portions. Finally, the end of the sealed spacer 100 can be inserted into other spacers.

[0085] Through the above processing process, a conventional spacer without the sheet-like structure 15 and the tapered section 16 can be processed into the sealed spacer 100. The whole process only needs to adopt the mechanical extrusion method without other processing methods. The processing process is simple, environmentally friendly and clean. It can completely complete the sealed spacer 100 through automated processing, greatly improving the processing efficiency and reducing the production cost. In addition, the sealed spacer 100 can be directly connected with the space spacer 200, that is, the spacer without the sheet-like structure 15 and the tapered section 16, by means of plugging, so as to form a spacer frame group in the insulating glass. The spacer frame group can directly form a closed ring to keep the gas in the insulating glass dry. The whole spacer frame group avoids the use of plugging parts and uses spacers, thus reducing the labor cost and the damage of auxiliary materials and greatly saving the cost.

[0086] Figure 9 It is a step flow chart of the production method of the insulating glass spacer frame group in the embodiment of the present invention. As Figure 9 shown, the production method of the insulating glass spacer frame group in the present application may include the following steps:

[0087] Before the processing and manufacturing process of the insulating glass, it is necessary to analyze in combination with the specifications of the insulating glass and the edge dimensions of the spacer frame group from the insulating glass before the processing and manufacturing process, so as to obtain the reasonable dimensions of the sealed spacer and the space spacer in the spacer frame group, and then make reasonable optimizations as much as possible in the selection or cutting of the space spacer 200 and the selection of the sealed spacer 100 in the inventory, so that the unusable part after the final cutting of the whole space spacer 200 can be minimized or no waste materials are generated, saving the production cost to a certain extent, improving the production efficiency and reducing the labor intensity. The above-mentioned spacer frame group can be adopted in the production method of the insulating glass spacer frame group.

[0088] S101: Calculate the total perimeter L of the initially set spacer frame based on the specifications of the insulating glass to be processed and the size of the spacer frame group from the edge of the insulating glass.

[0089] Before the process of manufacturing the insulating glass, calculate the total perimeter L of the initially set spacer frame based on the specifications of the insulating glass to be processed and the size of the spacer frame group from the edge of the insulating glass. The total perimeter L of the initially set spacer frame is the circumferential length formed by offsetting the edge of the insulating glass towards the center by the size of the spacer frame group from the edge of the insulating glass. At different positions on the edge of the insulating glass, the size of the spacer frame group from the edge of the insulating glass can be different, which can be determined according to actual requirements.

[0090] Taking the most common rectangular insulating glass as an example currently, Figure 10 This is a schematic diagram of the relationship between the total perimeter L of the spacer frame and the glass in the embodiment of the present invention. As Figure 10 shown, the total perimeter L of the initially set spacer frame L = [2(B1 - h1 - h2) + 2(B2 - h3 - h4)] × M, where M represents the correction factor, and usually the value of M ranges from 0.8 to 1.2.

[0091] After calculating the total perimeter L of the initially set spacer frame, determine whether the spacer frame with the total perimeter L of the initially set spacer frame can be processed according to the processing capacity of the automatic bending machine for bending the filled spacer and the space spacer. The total perimeter of the spacer frame that the automatic bending machine can process is the total perimeter S1 of the spacer frame of the smallest glass and the total perimeter S2 of the spacer frame of the largest glass. If the total perimeter L of the initially set spacer frame is less than or equal to the total perimeter S2 of the spacer frame of the largest glass and greater than or equal to the total perimeter S1 of the spacer frame of the smallest glass, then the total perimeter L of the initially set spacer frame meets the requirements. If not, it is necessary to adjust the size of the spacer frame group from the edge of the insulating glass within the feasible range. If it still does not meet the requirements after adjustment, it means that the specifications of the insulating glass are too large or too small, and the automatic bending machine cannot process it.

[0092] S102: Obtain the feasible length range of the filled spacer 100 based on the total perimeter L of the initially set spacer frame and the minimum frame - occupancy ratio a of the filled spacer 100.

[0093] In the above steps, a feasible length range of the sealed spacer 100 is obtained based on the initially set total perimeter L of the spacer frame and the minimum frame occupancy ratio a of the sealed spacer 100. The feasible length range of the sealed spacer 100 can specifically be greater than or equal to the initially set total perimeter L of the spacer frame multiplied by the minimum frame occupancy ratio a of the sealed spacer 100. As feasible, the minimum frame occupancy ratio a of the sealed spacer 100 is selected to be above 70%, so as to effectively ensure the dryness of the closed area formed by the spacer group frame in the insulating glass.

[0094] S103: Determine the fixed length specification of the sealed spacer 100 according to the feasible length range of the sealed spacer 100 and the situation of the sealed spacer 100 in the inventory.

[0095] After obtaining the feasible length range of the sealed spacer 100, specifically select the sealed spacer 100 that meets the feasible length range of the sealed spacer 100 according to the remaining storage situation of the sealed spacer 100 with different lengths in the factory inventory, so as to determine the fixed length specification of the sealed spacer 100 when processing the insulating glass of this order. Of course, if multiple insulating glasses of the same specification need to be processed, the quantity of the determined fixed length specification of the sealed spacer 100 can meet the usage of all insulating glasses of the same specification.

[0096] S104: Obtain the feasible length range of the spacer 200 according to the initially set total perimeter L of the spacer frame, the insertion size of the insertion interface between the sealed spacer 100 and the spacer 200, and the fixed length specification e of the sealed spacer 100.

[0097] In the above steps, according to the initially set total perimeter L of the spacer frame, the insertion size d of the insertion interface between the sealed spacer 100 and the spacer 200, and the fixed length specification of the sealed spacer 100, the feasible length range of the spacer 200 is calculated through the following formula:

[0098] The feasible length range of the spacer 200 ≤ L - e + 2d.

[0099] Among them, the insertion size d of the insertion interface between the sealed spacer 100 and the spacer 200 specifically refers to the overlapping length of the sealed spacer 100 and the spacer 200 at the insertion part.

[0100] S105: Determine the fixed length specification of the spacer 200 according to the feasible length range of the spacer 200 and the situation of the spacer 200 in the inventory.

[0101] After obtaining the feasible length range of the spacer bar 200, specifically select the spacer bar 200 that meets the feasible length range of the spacer bar 200 according to the remaining storage conditions of spacer bars of different lengths in the factory's inventory, so as to determine the fixed length specification of the spacer bar 200 when processing the insulating glass in this order. Generally speaking, the inventory is divided into two categories. One is the inventory of cut-off leftovers, that is, the materials remaining after the spacer bar is cut; the other is the inventory of new materials, that is, the materials of the spacer bar that have not been cut and have a longer length. First, the spacer bars in the cut-off leftovers in the inventory can be preferentially screened according to the fixed length specification of the spacer bar. If there is a match, directly select the spacer bar in the cut-off leftovers in the inventory as the fixed length specification of the spacer bar 200. If none of the spacer bars in the cut-off leftovers in the inventory can match, since the spacer bar 200 can be directly cut and used in cooperation with the filled spacer bar without other processing, therefore, a suitable length can be selected from the spacer bars 200 of different lengths in the inventory, so that one or more fixed length specifications of the spacer bar 200 can be directly cut out subsequently, and the length of the unusable spacer bar remaining after cutting a whole spacer bar is minimized, or there can be basically no remainder. The spacer bars 200 of different lengths can be new materials or cut-off leftovers with a longer length.

[0102] For example, the feasible length range of the spacer bar 200 is less than or equal to 20 cm. In the factory's inventory, the remaining storage conditions of spacer bars of different lengths are 90 cm, 100 cm, 110 cm, etc. If multiple pieces of insulating glass of the same specification need to be processed, the fixed length specification of the spacer bar 200 can be determined to be 20 cm at this time. Select a whole spacer bar with a length of 100 cm in the factory's inventory. Then, one spacer bar in the inventory can be cut into 5 sections later, each section being 20 cm. In this way, the length of the unusable spacer bar remaining after cutting is 0. Or the fixed length specification of the spacer bar 200 can be determined to be 18 cm. Select a whole spacer bar with a length of 90 cm in the factory's inventory. Then, one spacer bar in the inventory can be cut into 5 sections later, each section being 18 cm. In this way, the length of the unusable spacer bar remaining after cutting is 0. Of course, if the fixed length specification of the determined spacer bar 200 cannot be evenly divided after being matched with the length of the longer whole spacer bar in the factory's inventory, then a combination method with a smaller remainder can be selected as much as possible, so that the length of the unusable spacer bar remaining after cutting the whole spacer bar can be minimized. Of course, a new spacer bar can also be selected and cut again according to the fixed length specification. In the processing factory, the specifications of insulating glass are diverse. A new spacer bar can be cut into spacer bars of different lengths to fit insulating glass under different specifications. In this way, the remaining length after cutting the spacer bar can be made as short as possible. Usually, it can basically make the spacer bar have no leftover materials after cutting, which is beneficial to improving the utilization rate of the whole new spacer bar. Since the length of the spacer bar 200 is a value range and can be used within the value range, it has strong adaptability and a large tolerance. Therefore, most of the cutting leftovers can be fully utilized.

[0103] Certainly, the quantity of the fixed length specifications of the determined spacer bar 200 can meet the usage amount of the entire order.

[0104] S106: Check the total perimeter of the spacer bar frame formed by the fixed length specifications of the sealed spacer bar and the spacer bar 200.

[0105] In the above steps, make the total perimeter of the spacer bar frame formed by the fixed length specifications of the sealed spacer bar and the spacer bar 200 greater than or equal to the initial set total perimeter L of the spacer bar frame minus the free adjustment activity value c of the total length of the spacer bar frame, and less than or equal to the initial set total perimeter L of the spacer bar frame plus the free adjustment activity value c of the total length of the spacer bar frame. The free adjustment activity value c generally ranges from 0 to 30 mm.

[0106] If the verification fails, the total perimeter L of the initially set spacer frame is re-determined, and then the fixed length specification e of the sealed spacer 100 and the fixed length specification of the air spacer 200 are recalculated and selected according to the above-mentioned multiple steps. When re-determining the total perimeter L of the initially set spacer frame, the edge dimension between the spacer group frame and the insulating glass can be adjusted within a feasible range, so that the total perimeter L of the initially set spacer frame can be fine-tuned to a certain extent.

[0107] Alternatively, if the verification fails, only the fixed length specification of the air spacer can be re-determined. Since the air spacer that can be directly matched in the cutting leftovers in the inventory and does not require cutting may have been preferentially selected as the fixed length specification before, at this time, a new fixed length specification that needs to cut the air spacer in the leftovers or new materials can be determined, so that the subsequent verification can be passed.

[0108] S107: Screen the air spacers in the cutting leftovers in the inventory according to the fixed length specification of the air spacer 200. If there is a match, directly select and use it; if none of the air spacers 200 in the cutting leftovers in the inventory can match, cut the air spacers in the inventory according to the fixed length specification of the air spacer to obtain the air spacer 200 with the fixed length specification.

[0109] After passing the verification, screen the air spacers in the cutting leftovers in the inventory according to the fixed length specification of the air spacer 200. If there is a match, directly select and use it, that is, if the length dimension can directly meet the value range of the fixed length specification, directly select and use it. If none of the air spacers 200 in the cutting leftovers in the inventory can match, cut the air spacers in the inventory according to the fixed length specification of the air spacer to obtain the air spacer 200 with the fixed length specification. The length of the final waste after cutting the whole air spacer 200 can be minimized, or there can be basically no remainder. The above-mentioned cut air spacers can be new air spacers or air spacer leftovers with a longer length.

[0110] S108: Bend the air spacer 200 with the fixed length specification and the sealed spacer 100 with the fixed length specification, and then form a spacer group frame by means of plug-in connection.

[0111] In the above steps, such as Figure 1 and Figure 2As shown, the fixed-length sealed spacer 100 can be bent multiple times by an automated bending machine, and the fixed-length spacer 200 directly selected or cut can be bent once or not by an automated bending machine, and then formed into a spacer assembly frame by plugging. For example, the sealed spacer 100 has a first end and a second end opposite to each other, and both the first end and the second end have a plug-in structure 1002, and the spacer 200 has a third end and a fourth end opposite to each other, and the first end is inserted into the third end, and the second end is inserted into the fourth end, thereby forming a spacer assembly frame. The sealed spacer 100 is a spacer that has been pre-filled with a desiccant 1003.

[0112] In the above steps, as feasible, after the fixed length spacer 200 and the fixed length sealing spacer 100 are bent, the length X of the end of the fixed length sealing spacer 100 from the nearest bending point is greater than or equal to the preset distance S, and the length Y of the end of the spacer 200 from the nearest bending point is greater than or equal to the preset distance S. The above method can ensure the firmness and stability of the plug-in joint of the spacer 200 and the sealing spacer 100, and avoid the bending joint affecting the firmness and stability of the plug-in joint due to the close distance between the plug-in joint and the bending joint. The preset distance S generally needs to be greater than or equal to 20 mm.

[0113] S109: forming a through hole 1001 by laser drilling, punching or piercing on one side of the dry gas space formed by the sealing spacer 100 or at any position of the circumference of the plug-in structure.

[0114] After the sealed spacer 100 forms a spacer assembly frame, when it is to be installed between two sheets of glass, Figure 1 and Figure 2 As shown, a through hole 1001 is formed on one side of the sealed spacer 100 that is wound around to form a dry gas space or at any position of the plug-in structure in the circumference. Since there is always a certain gap between the plug-in structure and the spacer 200, the through hole 1001 on the plug-in structure can be connected to the dry gas space through the gap. The above method can ensure that the sealed spacer 100 installed in the two sheets of glass can play a role in dehumidification and drying. Before the sealed spacer 100 forms a spacer assembly frame and is installed in the two sheets of glass, the side wall of the sealed spacer 100 is always sealed and there is no through hole 1001. This ensures that the desiccant 1003 filled in advance inside the sealed spacer 100 will not fail, and the desiccant 1003 will not be filled into the sealed spacer 100 when the sealed spacer 100 is installed in the two sheets of glass, which will cause the desiccant 1003 to contaminate the glass during the filling process.

[0115] In the above implementation process, through-hole 1001 can be efficiently processed by laser drilling, stamping or punching. Preferably, through-hole 1001 is formed by laser drilling, which can greatly improve the processing efficiency and ensure the quality of through-hole 1001.

[0116] As an alternative, on one side of the space spacer 200 that winds around to form the dry gas space, through-hole 1001 can be processed or not.

[0117] S110: After the through-hole 1001 is to be formed, assemble the spacer frame with at least two pieces of glass to form a insulating glass.

[0118] In the above steps, the spacer frame can be clamped between two pieces of glass, or multiple spacer frames can be respectively clamped between multiple pieces of glass to form a insulating glass. The end faces of the spacer frame in contact with the glass can be pasted with an adhesive to ensure the sealing effect.

[0119] This application can analyze the specifications of the processed insulating glass to obtain the fixed length specifications of the sealed spacer 100 filled with desiccant 1003 and the fixed length specifications of the space spacer 200 without filling desiccant 1003, so as to obtain an optimized matching scheme. After bending the sealed spacer 100 and / or the space spacer 200, form a spacer frame by plugging. The whole process is convenient and flexible, can effectively make full use of the surplus materials of the space spacer 200, or cut the whole space spacer 200 so that the unusable part is minimized or no waste is generated, thereby saving production costs. At the same time, the connectors used in the traditional process can also be omitted, which can also reduce production costs and labor intensity.

[0120] This application has the characteristics of high flexibility and can be applied to the processing of insulating glass with various size specifications; for the sealed spacer 100 with its own desiccant 1003 for sealing, the process of filling desiccant 1003 in the process of forming insulating glass is omitted, avoiding the pollution of the glass by the desiccant 1003 dust, reducing the exposure time of the desiccant 1003 to the air before the insulating glass is assembled, and effectively improving the processing quality and service life of the insulating glass.

[0121] In addition, both the sealed spacer 100 and the space spacer 200 in this application can be processed by automated production, and the plug-in connection between the two to form a spacer frame can also be directly completed by automated machinery, without the need for manual participation, because it can free the high-intensity and repetitive manual labor, and automated production can also greatly improve production efficiency and product quality.
