Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of glass production, and in particular to an assembly method of functional elements, glass and a vehicle. Background Art
[0002] Currently, tinted glass is created by sandwiching functional components (such as polymer dispersed liquid crystal) between two layers of glass. This tinted glass is often used in vehicle sunroofs, door glass, or other applications where light transmittance needs to be adjusted.
[0003] Currently, in the production process of tinted glass, it is first necessary to cut out a hollow area on the PVB film layer that matches the outer contour of the PDLC element. Then, the PDLC element is embedded in the hollow area. Finally, the PVB film layer and the PDLC element are sandwiched between the glass on both sides for the lamination process. In this process, the hollow area on the PVB film layer is usually cut using a precision cutting machine, a laser cutting machine, or manual cutting. However, all three cutting methods have their own disadvantages:
[0004] 1. Precision cutting machine cutting solution: The PVB film layer is laid flat on the operating table of the precision cutting machine, and the mechanical arm on the precision cutting machine is controlled to move, thereby driving the cutting knife on the mechanical arm to cut the PVB film layer. However, because the PVB film layer is soft and the thickness varies from place to place, when the precision cutting machine program cuts according to the preset PVB film thickness, it is easy to cause some parts of the PVB film layer (i.e., the actual thickness is less than the preset thickness) to overcut and cut into the operating table, which is very likely to scratch the operating table. Dust, debris, dirt, etc. formed by cutting on the operating table will adhere to the PVB film layer, thereby affecting the quality of the finished glass. In addition, the scratched operating table will leave scratches, resulting in an uneven operating table surface. In the subsequent cutting process, the problem of uneven placement of the PVB film layer is further exacerbated, creating a vicious cycle.
[0005] 2. Laser cutting solution: Laser is used to directly cut the PVB film layer. However, during this process, the laser beam will heat the cutting position of the PVB film layer to the ignition temperature and burn, thereby generating heat and a large amount of smoke. Since the lamination process is carried out in a closed lamination room, the laser cutting method is not only easy to damage the PVB film layer, but also poses a safety hazard (possibly causing a fire). The smoke and dust generated are very likely to adhere to the PVB film layer, thereby easily causing pollution to the PVB film layer and the formed glass.
[0006] 3. Manual cutting solution: Manual cutting needs to be completed manually. This method generates less debris and dust pollution during the cutting process than the above two solutions. However, the cutting position and cutting size need to rely entirely on manual positioning and measurement, which cannot guarantee the accuracy requirements, and the cutting efficiency is low, resulting in low production efficiency.
[0007] Regarding the related technologies, there are problems in cutting the PVB film layer during the production of tinted glass, such as overcutting, safety hazards, and low cutting accuracy and efficiency. Currently, no effective solution has been given.
[0008] Therefore, the present invention provides a method for assembling a functional element, glass, and a vehicle to solve at least one of the above-mentioned technical problems. Summary of the Invention

[0031] In a preferred embodiment of the present invention, an infrared distance measuring device is provided on the film cutting device.
[0032] In the step S3, the distance between the cutting blade of the film cutting device and the first film is detected by the infrared distance measuring device to control the cutting depth of the cutting blade.
[0033] The present invention provides a glass comprising:
[0034] Two glass layers;
[0035] The three-layer membrane structure formed by the above-mentioned method of assembling functional elements is sandwiched between the two glass layers.

The second diaphragm protects the operating table. Even if overcutting occurs when cutting the first diaphragm, the overcut position will only cause cutting marks on the second diaphragm without damaging the operating table.

[0071] The present invention still uses the existing membrane cutting equipment 6 to cut the membrane, and places the membrane to be cut horizontally on the operating table 601 of the membrane cutting equipment 6. By controlling the movement of the three-dimensional robotic arm 602 on the membrane cutting equipment 6, the cutting knife 603 at the end of the three-dimensional robotic arm 602 is driven to move and cut the membrane according to a preset path. A hollow portion 101 that can be used to accommodate the functional element 5 is cut at a preset position on the membrane, and the hollow portion 101 can be used to assemble the functional element 5.
[0072] The film cutting device 6 used in the present invention can be but not limited to a precision cutting machine. The precision cutting machine of the present invention is as follows: Figure 11 As shown, it includes a horizontally arranged operating table 601, and a three-dimensional robotic arm 602 includes a first slide rail 604 disposed at the edge of the operating table 601 and extending in the X direction.

The X, Y, and Z directions can be the X-axis, Y-axis, and Z-axis directions in a three-dimensional coordinate system, respectively.
[0073] The first slide rail 604 , the second slide rail 606 and the third slide rail 607 may be transmission chains extending along the X direction, the Y direction and the Z direction respectively, and the three transmission chains are driven to rotate by three motors respectively.
[0074] Implementation Method 1
[0075] like Figures 1 to 11 As shown, the present invention provides a method for assembling a functional element, which comprises the following steps:
[0076] Step S1: Before cutting the first membrane 1, the first membrane 1 and the second membrane 2 are stacked to form a double-layer membrane structure 3;
[0077] Step S2: placing the double-layer membrane structure 3 on the operating table 601 of the membrane cutting device 6, with the second membrane 2 located between the first membrane 1 and the operating table 601 (i.e., the second membrane 2 is placed under the first membrane 1);
[0078] Step S3: using the film cutting device 6 to cut the first film 1 to form a hollow portion 101;
[0079] Step S4 : disposing the functional element 5 in the hollow portion 101 .
[0080] In the assembly method of the functional element of the present invention, before cutting the first diaphragm 1, the first diaphragm 1 and the second diaphragm 2 are first stacked to form a double-layer membrane structure 3; and when cutting the first diaphragm 1, the stacked first diaphragm 1 and the second diaphragm 2 are placed on the operating table 601 of the diaphragm cutting equipment 6, and the second diaphragm 2 is located between the first diaphragm 1 and the operating table 601, and the second diaphragm 2 is padded under the first diaphragm 1. The second diaphragm 2 acts as a gasket and can protect the operating table 601. Even if overcutting occurs when cutting the first diaphragm 1, the overcut position will only cause cutting marks to appear on the contact surface between the second diaphragm 2 and the first diaphragm 1, and will not cause damage to the operating table 601. Therefore, in the present invention, when assembling the functional element 5, the existing diaphragm cutting equipment 6 is still used to cut the first diaphragm 1, and the operating table 601 will not be scratched, thereby ensuring cutting accuracy and efficiency while having higher safety.
[0081] In the present invention, since damage to the operating table 601 can be avoided when cutting the first diaphragm 1, dust, debris, dirt and other pollutants formed by cutting will not adhere to the diaphragm. In addition, since the first diaphragm 1 and the second diaphragm 2 can be made of the same material, and both can be made of PVB material, the first diaphragm 1 and / or the second diaphragm 2 can be softened by high-temperature heating and pressurization, or the surface of the first diaphragm 1 and / or the surface of the second diaphragm 2 can be made flowable (that is, the surface of the first diaphragm 1 and / or the surface of the second diaphragm 2 has a certain fluidity by high-temperature heating and pressurization). In the later stage of the sheet-joining and pressing process, the material near the location of the cutting mark can be squeezed to the cutting mark, thereby filling the cutting mark on the second diaphragm 2. After pressing, the cutting mark can be kept smooth, and the unevenness on the second diaphragm 2 can be avoided, thereby ensuring that the product has good quality after molding.
[0082] In an optional embodiment of the present invention, in step S1, the first diaphragm 1 and the second diaphragm 2 are welded and fixed. That is, to ensure the stability of the relative position between the first diaphragm 1 and the second diaphragm 2 and to prevent relative movement during the cutting process, which would cause the cut hollow portion 101 to be unable to fit the functional element 5, the first diaphragm 1 and the second diaphragm 2 are welded and fixed before being placed on the operating table 601 of the diaphragm cutting device 6. This ensures that the relative position of the first diaphragm 1 and the second diaphragm 2 does not change during the subsequent cutting process, ensures cutting accuracy, and ensures that the functional element 5 can be precisely embedded in the hollow portion 101 when assembled.
[0083] Further, such as Figures 4 to 9 As shown, multiple weld points 4 are provided between the first diaphragm 1 and the second diaphragm 2. These weld points 4 are spaced and evenly distributed along the outer contour of the first diaphragm 1 and extend through both the first diaphragm 1 and the second diaphragm 2. The spacing between adjacent weld points 4 can be, but is not limited to, 200-300 mm. The number of weld points 4 and the spacing between adjacent weld points 4 are not specifically limited; they are determined to ensure stable welding between the first diaphragm 1 and the second diaphragm 2.
[0084] In an optional embodiment of the present invention, in step S1, the shapes and sizes of the first diaphragm 1 and the second diaphragm 2 can be preselected to ensure that the outer contour of the first diaphragm 1 coincides with the outer contour of the second diaphragm 2 as much as possible, so that after the first diaphragm 1 and the second diaphragm 2 are welded, they can form a whole. No matter where the first diaphragm 1 is cut, it will not exceed the range of the second diaphragm 2, thereby ensuring that the operating table 601 will not be scratched. Of course, in some embodiments, the outer contour of the first diaphragm 1 can also be preset to be located inside the outer contour of the second diaphragm 2 (that is, the area of the second diaphragm 2 is larger than the area of the first diaphragm 1), so that the vertical projection of the first diaphragm 1 completely falls on the second diaphragm 2. In this case, no matter where the first diaphragm 1 is cut, it can be ensured that it will not exceed the range of the second diaphragm 2, thereby ensuring that the operating table 601 will not be scratched.
[0085] In an optional embodiment of the present invention, in step S1, the thickness of the second film 2 can be preselected to be greater than or equal to the thickness of the first film 1. Before cutting the first film 1, the cutting depth of the cutting blade 603 of the film cutting device 6 needs to be set according to the thickness of the first film 1. To ensure that the cutting position on the first film 1 can be smoothly cut, the cutting depth of the cutting blade 603 should be set to be greater than the maximum thickness of the first film 1. After the thickness of the second film 2 is set to be greater than or equal to the thickness of the first film 1, even if overcutting occurs at the minimum thickness position on the first film 1, it can be ensured that the cutting blade 603 will not penetrate the second film 2 and cause damage to the operating table 601.
[0086] In the present invention, the length and width of the first membrane 1 and the second membrane 2 can range from, but are not limited to, 300×300 mm to 2000×1400 mm. Of course, the first membrane 1 and the second membrane 2 can also be selected to have a length and width that matches the size of the glass layer to be laminated.
[0087] In an optional embodiment of the present invention, a suction cup can be pre-set on the operating table 601 of the membrane cutting equipment 6. In step S2, the bottom surface of the second membrane 2 is adsorbed by the suction cup set on the operating table 601, so that the double-layer membrane structure 3 is firmly adsorbed and fixed on the operating table 601 to ensure that no displacement occurs when the first membrane 1 is cut, thereby ensuring accurate cutting of the first membrane 1.
[0088] In an optional embodiment of the present invention, step S3 includes:
[0089] Step S301: Presetting a cutting position on the first film 1;
[0090] Among them, the preset cutting position is located in the middle area or near the middle area of the first diaphragm 1 as much as possible to ensure that after the functional element 5 is assembled, the functional element 5 can occupy a larger area in the middle or near the middle of the first diaphragm 1, so that the overall dimming function of the product can be realized after the product is formed.
[0091] Step S302: cutting at the cutting position by the film cutting device 6;
[0092] Among them, Figure 11 As shown, the motion trajectory of the three-dimensional robotic arm 602 on the membrane cutting device 6 can be preset. By controlling the three-dimensional robotic arm 602 to move according to the preset motion trajectory, the three-dimensional robotic arm 602 drives the cutting knife 603 at its end to move and cut the first membrane 1 according to a preset path, and cuts at a preset position on the first membrane 1 to form a hollow portion 101 that can be used to accommodate the functional element 5.
[0093] In this embodiment, the shape of the hollow portion 101 can be preset according to the shape of the functional element 5 to be accommodated. The shape of the hollow portion 101 can be, but is not limited to, a rectangle, a circle, a heart shape, or a trapezoid.
[0094] Further, such as Figure 11As shown, an infrared distance measuring device 9 is provided on the film cutting device 6 near the end of the three-dimensional robotic arm 602. In step S3, while controlling the cutting blade 603 of the film cutting device 6 to cut the first film 1, the infrared distance measuring device 9 detects the distance between the cutting blade 603 of the film cutting device 6 and the first film 1 to control the cutting depth of the cutting blade 603 and avoid overcutting as much as possible. If the monitoring detects that the cutting depth of the cutting blade 603 is greater than or equal to the sum of the thicknesses of the first film 1 and the second film 2, which may cause scratches on the operating table 601, the film cutting device 6 is immediately stopped and the cutting depth is readjusted. The infrared distance measuring device 9 can be, but is not limited to, an infrared sensor.
[0095] Step S303: Figure 6 and Figure 7 As shown, after the first diaphragm 1 is cut, the cut portion of the first diaphragm 1 can be removed by connecting a mechanical clamp or manually to form a hollow portion 101 on the first diaphragm 1; wherein the hollow portion 101 has the same outer contour as the functional element 5.
[0096] In an optional embodiment of the present invention, Figure 2 and Figure 10 As shown, after step S4, the following steps are further included:
[0097] Step S5: Before the lamination process, a third membrane sheet 7 is laminated on the first membrane sheet 1 to form a three-layer membrane structure 8;
[0098] Step S6: glass layers are respectively arranged on both sides of the three-layer membrane structure 8 , and the two glass layers are laminated by heating and pressurizing to sandwich the three-layer membrane structure 8 between the two glass layers.
[0099] In the present invention, the first diaphragm 1, the second diaphragm 2 and / or the third diaphragm 7 can be made of, but not limited to, PVB (polyvinyl butyral) material or EVA (ethylene-vinyl acetate copolymer) material.
[0100] In some embodiments of the present invention, during the welding process of the first diaphragm 1 and the second diaphragm 2, the welding point 4 should be set as close as possible to the edge position of the first diaphragm 1 and the second diaphragm 2, or the position of the welding point 4 should be set according to the black edge printing position on the glass layer (the original printing area on the glass), so that after the lamination process in step S6, the black edge printing position on the glass layer can cover each welding point 4, thereby avoiding the possibility that the electric soldering iron may leave darker welding point marks on the first diaphragm 1 and / or the second diaphragm 2 during the welding process, thereby avoiding the dark welding point marks affecting the appearance of the molded product.
[0101] In an optional embodiment of the present invention, Figure 10 As shown, in step S5, the first diaphragm 1 and the third diaphragm 7 are welded and fixed. That is, in order to ensure that the first diaphragm 1, the second diaphragm 2 and the third diaphragm 7 are sandwiched as a whole between the two glass layers during the lamination process, and to ensure the stability of the product after lamination, the third diaphragm 7 is stacked on the first diaphragm 1 before lamination, and the first diaphragm 1 and the third diaphragm 7 are welded and fixed to ensure the stability after the functional element 5 is assembled.
[0102] Furthermore, multiple welding points 4 are provided between the first diaphragm 1 and the third diaphragm 7, and the number and position of the multiple welding points 4 between the first diaphragm 1 and the third diaphragm 7 are the same as the multiple welding points 4 between the first diaphragm 1 and the second diaphragm 2, so as to ensure that the first diaphragm 1, the second diaphragm 2 and the third diaphragm 7 can form a whole.
[0103] Furthermore, the shape and size of the third diaphragm 7 can be pre-selected to ensure that the outer contour of the third diaphragm 7 coincides with the outer contour of the first diaphragm 1 as much as possible, so that after the first diaphragm 1 and the third diaphragm 7 are welded, the first diaphragm 1, the second diaphragm 2 and the third diaphragm 7 can form a whole for subsequent lamination processing.
[0104] In the present invention, the length and width of the third diaphragm 7 may range from, but are not limited to, 300×300 mm to 2000×1400 mm. Of course, the length and width of the third diaphragm 7 may also be selected based on the actual length and width of the first diaphragm 1 so that the third diaphragm 7 can be compatible with the first diaphragm 1.
[0105] In an optional embodiment of the present invention, in step S6, since high-temperature heating and pressurization are required during the glass lamination process, the high-temperature heating and pressurization environment during the lamination process can soften the first film 1 and / or the second film 2, or make the surface of the first film 1 and / or the surface of the second film 2 flowable (that is, the surface of the first film 1 and / or the surface of the second film 2 has a certain fluidity through high-temperature heating and pressurization). In combination with the extrusion of the first film 1, the second film 2 and the third film 7 during the lamination process, the material near the location of the cutting mark (the material may be part of the material on the surface of the second film 2, or may be part of the material on the surface of the first film 1) can be squeezed to the cutting mark on the second film 2, thereby filling the cutting mark on the second film 2. After pressing, the cutting mark can be kept smooth, and unevenness can be avoided on the second film 2, thereby ensuring that the glass after lamination has good quality.
[0106] In the above embodiment, in step S6, the temperature for laminating the two glass layers is 110°C-150°C; and / or the pressure for laminating the two glass layers is 0.9 MPa-1.2 MPa. The above laminating effect can be achieved by the above temperature and pressure environment.
[0107] The functional element 5 used in the present invention can be a PDLC dimming film or an EC dimming film (wherein, the PDLC dimming film or the EC dimming film are a type of liquid crystal electrically controlled dimming film). Of course, the functional element 5 can also be a functional element such as a sound element.
[0108] The features and advantages of the functional element assembly method of the present invention are:
[0109] 1. The assembly method of this functional component can not only ensure cutting accuracy, but also effectively avoid problems such as debris pollution, dust pollution, and fire hazards that are easily caused by traditional processes, ensuring that the formed glass has good quality.
[0110] Second, the assembly method of the functional element can improve the yield rate of glass assembly, avoid the cumbersome steps and extra workload caused by cleaning debris, greatly save work time, and avoid waste of manpower and material resources.
[0111] 3. The assembly method of the functional element can effectively avoid cutting errors caused by changes in the thickness of the first diaphragm 1 by providing an infrared sensor, thereby achieving high-quality and high-precision cutting.
[0112] Implementation Method 2
[0113] The present invention provides a glass comprising two glass layers and a three-layer membrane structure 8. The three-layer membrane structure 8 is formed by the above-mentioned assembly method of functional elements. The three-layer membrane structure 8 is sandwiched between the two glass layers, and the two glass layers are combined by high-temperature heating and pressurization.
[0114] In an optional embodiment of the present invention, Figure 10 As shown, the three-layer membrane structure includes a second diaphragm 2, a first diaphragm 1 and a third diaphragm 7 stacked in one direction. The middle part or near the middle part of the first diaphragm 1 has a hollow portion 101, and the shape of the hollow portion 101 is adapted to the shape of the functional element 5. The functional element 5 is embedded in the hollow portion 101. The first diaphragm 1 is sandwiched between the second diaphragm 2 and the third diaphragm 7. The first diaphragm 1 and the second diaphragm 2 and / or the first diaphragm 1 and the third diaphragm 7 can be fixed by welding, so that the first diaphragm 1, the second diaphragm 2 and the third diaphragm 7 form an integral structure, thereby ensuring the stability of the three-layer membrane structure after forming.
[0115] Furthermore, multiple welding points 4 are set between the first diaphragm 1 and the second diaphragm 2. The multiple welding points 4 are spaced and evenly distributed along the outer contour of the first diaphragm 1. The multiple welding points 4 pass through the first diaphragm 1 and the second diaphragm 2 respectively to achieve a stable connection between the first diaphragm 1 and the second diaphragm 2.
[0116] Furthermore, the first diaphragm 1 and the third diaphragm 7 can be connected in the same manner as the first diaphragm 1 and the second diaphragm 2. That is, multiple welds 4 are provided between the first diaphragm 1 and the third diaphragm 7. These welds 4 are spaced and evenly distributed along the outer contour of the first diaphragm 1, and the welds 4 extend through the first diaphragm 1 and the third diaphragm 7, respectively, to achieve a stable connection between the first diaphragm 1 and the third diaphragm 7. In the stacking direction, the welds 4 between the first diaphragm 1 and the second diaphragm 2 are positioned opposite to the welds 4 between the first diaphragm 1 and the third diaphragm 7, thereby minimizing the number of welds 4 exposed on the diaphragms. This improves the appearance of the three-layer membrane structure after formation, enhancing the display effect and user experience.
[0117] In the above embodiment, the distance between two adjacent welding points 4 may be, but is not limited to, 200-300 mm.
[0118] In an optional embodiment of the present invention, the solder joint 4 is located near the edge of the first diaphragm 1 and has a printing position (the original printing area on the glass) near the edge of the glass layer. After the glass layer and the three-layer membrane structure 8 are combined, the printing position covers the solder joint 4 on the three-layer membrane structure 8, thereby achieving the purpose of shielding the solder joint 4, avoiding the possibility that the electric soldering iron may leave darker solder joint marks exposed on the first diaphragm 1, the second diaphragm 2 and / or the third diaphragm 7 during the soldering process, thereby avoiding the dark solder joint marks affecting the appearance of the molded product.
