Description

Technical Field

[0001] This invention relates to the field of glass lamination technology, and in particular to laminated glass lamination systems and methods. Background Technology

[0002] Laminated glass manufacturing involves a lamination step, which refers to stacking the inner glass sheet, the diaphragm, and the outer glass sheet together. The lamination surface is the side of the inner glass sheet that is used to bond with the diaphragm, and the same applies to the outer glass sheet. During transport and lamination, contact with the lamination surface should be avoided as much as possible to prevent contamination and optical quality defects in the final laminated glass. Generally, lamination systems use multiple transport lines to separately transport the inner and outer glass sheets, resulting in a complex system structure. Summary of the Invention

[0003] This invention addresses the problem of complex structures in laminated glass systems by proposing a laminated glass lamination system and a laminated glass lamination method to reduce system complexity.

[0004] A laminated glass bonding system, comprising:

[0005] A conveying mechanism is used to sequentially transport the first glass and the second glass to the flipping start station;

[0006] Assembly device;

[0007] The first gripping mechanism is used to sequentially transfer the first glass and the second glass, which are conveyed to the flipping starting station, to the laminating device, and flip the first glass and the second glass during the transfer process so that the laminating surface of the first glass faces upward and the laminating surface of the second glass faces downward.

[0008] The second gripping mechanism is used to transfer the diaphragm to the lamination surface of the first glass, and then place the second glass onto the diaphragm.

[0009] In one embodiment, the conveying mechanism includes a first conveying section and a second conveying section, the second conveying section being located at the flipping start station, the first conveying section being located upstream of the second conveying section, and the second conveying section including a first sub-conveying section and a second sub-conveying section, the first sub-conveying section being located between the first conveying section and the second sub-conveying section;

[0010] The first sub-transfer segment and the second sub-transfer segment can move relative to each other in the transport direction, and can move to a state where they are spaced apart;

[0011] Alternatively, the first sub-transfer segment may be extendable in the transport direction, allowing it to be spaced apart from the second sub-transfer segment;

[0012] Alternatively, the second sub-transfer segment may be extendable in the transport direction, allowing it to be spaced apart from the first sub-transfer segment.

[0013] In one embodiment, the conveying mechanism includes a first conveying section and a second conveying section, the second conveying section being located at the flipping start station, the first conveying section being located upstream of the second conveying section, and the second conveying section including a first sub-conveying section and a second sub-conveying section, the first sub-conveying section being located between the first conveying section and the second sub-conveying section;

[0014] The first sub-transfer section includes a telescopic conveyor belt, which is mounted on a sliding module. The sliding module includes a second slide rail and a second slider that is slidably fitted on the second slide rail. The guiding direction of the second slide rail is parallel to the conveying direction. One end of the telescopic conveyor belt near the first transfer section is fixed relative to the second slide rail, and the other end of the telescopic conveyor belt near the second sub-transfer section is connected to the second slider.

[0015] In one embodiment, a support frame is provided below the second conveying segment, and a notch is provided on the support frame at a position below the second sub-conveyor segment. The notch starts below the junction of the first and second sub-conveyor segments and penetrates the support frame along the conveying direction of the second sub-conveyor segment. The notch penetrates at least one side of the support frame in a direction perpendicular to the conveying direction.

[0016] In one embodiment, the laminating device includes a servo module, and the laminating device is provided with a first placement position, a second placement position and a laminating position, and the servo module is arranged between the first placement position and the laminating position;

[0017] The first gripping mechanism has at least two working modes. In one working mode, the first gripping mechanism can transfer the first glass conveyed to the flipping start station to the servo module located at the first placement position, and flip the first glass during the transfer process. In another working mode, the first gripping mechanism can transfer the second glass conveyed to the flipping start station to the second placement position, and flip the second glass during the transfer process.

[0018] The second gripping mechanism is capable of placing the diaphragm onto the lamination surface of the first glass at the lamination position, and then placing the second glass at the second placement position onto the diaphragm.

[0019] In one embodiment, the laminated glass bonding system further includes a point heating unit for point heating the bonded glass in the bonding device;

[0020] The laminated glass assembly system also includes a three-dimensional contour measuring instrument A, which is used to measure the relative positions of the contours of the first glass, the film and the second glass after the point heating unit is point heated. The three-dimensional contour measuring instrument A is electrically connected to the second gripping mechanism.

[0021] In one embodiment, the second gripping mechanism includes a first gripping head and a second gripping head. The first gripping head and the second gripping head are respectively used to grip two different parts of the diaphragm. The surface of the first gripping head that contacts the diaphragm is a first positioning surface, and the surface of the second gripping head that contacts the diaphragm is a second positioning surface. The first gripping head and the second gripping head are movably coupled to allow for a first state and a second state between them. In the first state, the angle between the first positioning surface and the second positioning surface is a1, and in the second state, the angle between the first positioning surface and the second positioning surface is a2, and a1 and a2 are not equal. The distance between any point on the first positioning surface and any point on the second positioning surface is equal in both the first state and the second state.

[0022] In one embodiment, the first gripping head and the second gripping head are rotatable relative to each other, and the axis of rotation is parallel to both the first positioning surface and the second positioning surface. The first gripping head and the second gripping head are also movable relative to each other, and the direction of movement intersects the axis of rotation between them.

[0023] In one embodiment, the first gripper head and the second gripper head are rotatably coupled via a first rotating shaft. Both the first positioning surface and the second positioning surface are parallel to the axial direction of the first rotating shaft. The first rotating shaft is slidable relative to the first gripper head and / or the second gripper head, and the sliding direction is perpendicular to the axial direction of the first rotating shaft.

[0024] In one embodiment, the second gripper head is provided with a first slide rail, and a first slider is slidably engaged on the first slide rail. The first slider is rotatably engaged with the first gripper head through the first rotating shaft, and the sliding direction of the first slider on the first slide rail is perpendicular to the axial direction of the first rotating shaft.

[0025] The second gripping head is also provided with a guide member, and the guide member is provided with a guide groove. The first gripping head is also provided with a guide wheel, which is slidably mounted in the guide groove. The guide wheel is not located on the axis of the first rotating shaft. The guiding direction of the guide groove is perpendicular to the axis of the first rotating shaft. The guiding direction of the guide groove intersects with the sliding direction of the first slider on the first slide rail.

[0026] In one embodiment, both the first gripper head and the second gripper head include a support and a plurality of suction cups disposed on the support. The suction surfaces of the plurality of suction cups included in the first gripper head constitute the first positioning surface, and the suction surfaces of the plurality of suction cups included in the second gripper head constitute the second positioning surface. The two supports are movably engaged so that there are a first state and a second state between the first gripper head and the second gripper head.

[0027] A method for laminating laminated glass includes the following steps:

[0028] The first glass and the second glass are sequentially conveyed to the flipping start station along the same conveying direction, with the lamination surface of the first glass facing down and the lamination surface of the second glass facing up during this conveying process;

[0029] The first glass and the second glass at the flipping starting station are transferred to the laminating device in sequence. During the transfer, both the first glass and the second glass are flipped so that the laminating surface of the first glass is facing up and the laminating surface of the second glass is facing down.

[0030] First, the diaphragm is transferred to the first glass on the laminating device, and then the second glass on the laminating device is placed on the diaphragm.

[0031] In one embodiment, the first glass is the outer pane of a curved laminated glass, with the concave surface of the outer pane serving as the lamination surface; the second glass is the inner pane of the curved laminated glass, with the convex surface of the inner pane serving as the lamination surface.

[0032] In one embodiment, transferring the diaphragm onto the first glass of the laminating device specifically includes the following steps:

[0033] Step 1: Use the gripping heads on the second gripping mechanism to grip different parts of the diaphragm. Some of the gripping heads have a first positioning surface for contacting the diaphragm, and some of the gripping heads have a second positioning surface for contacting the diaphragm. At this time, the first positioning surface and the second positioning surface that the gripping head contacts different parts of the diaphragm are on the same horizontal plane.

[0034] Step 2: Control the relative movement between each gripping head to form an angle between the first positioning surface and the second positioning surface, and to bend the diaphragm.

[0035] In one embodiment, the distance between any point on the first positioning surface and any point on the second positioning surface remains equal before and after bending of the diaphragm.

[0036] In one embodiment, in step two, the diaphragm is bent to form a V-shape.

[0037] The above solution provides a laminated glass lamination system and method. During use, both the first and second glass panes are placed on a conveying mechanism, which sequentially transports them to the flipping initiation station. Then, a first gripping mechanism sequentially transfers the first and second glass panes from the flipping initiation station to the lamination device for lamination. Because the first gripping mechanism flips and changes the orientation of the first and second glass panes during transfer, the first glass pane is ultimately placed in the lamination device with its lamination surface facing upwards, and the second glass pane facing downwards. A second gripping mechanism then places a diaphragm onto the lamination surface of the first glass pane, and then places the second glass pane onto the diaphragm, completing the lamination process. By using a single conveying mechanism to transport the first and second glass panes, and then combining this with the first gripping mechanism to grip and flip the two types of glass separately, the complexity of the entire system is reduced.

Detailed Implementation

[0058] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0059] like Figure 1 and Figure 2 As shown, this application provides a laminated glass lamination system 10 in some embodiments. The laminated glass lamination system 10 includes a conveying mechanism 11, a lamination device 12, a first gripping mechanism 13, and a second gripping mechanism 14.

[0060] The conveying mechanism 11 is used to sequentially transport the first glass 20 and the second glass 30 to the flipping start station. This can be understood as the first glass 20 and the second glass 30 used to manufacture the laminated glass 50 being sequentially transported to the flipping start station by the same conveying mechanism 11. Specifically, during the manufacturing process, the first glass 20 and the second glass 30 can be placed sequentially on the conveying mechanism 11, and then the conveying mechanism 11 sequentially transports the first glass 20 and the second glass 30 to the flipping start station.

[0061] The first glass 20 and the second glass 30, upon reaching the flipping starting position, are sequentially transferred by the first gripping mechanism 13 to the laminating device 12. During the transfer, the first glass 20 and the second glass 30 are flipped so that the laminating surface of the first glass 20 faces upward and the laminating surface of the second glass 30 faces downward. Additionally, during the transfer, the first gripping mechanism 13 can also rotate about an axis perpendicular to the horizontal plane, rotating the first glass 20 and the second glass 30 180°. Figure 1 As shown, when on the conveying mechanism 11, the exposed edges of both the first glass 20 and the second glass 30 are located to the side; when in the laminating device 12, the exposed edges of both the first glass 20 and the second glass 30 face the forward direction. The rotation axis of the flipping action is set in the horizontal direction, and the rotation axis of the rotating action is arranged in a direction perpendicular to the horizontal plane.

[0062] When the first glass 20 and the second glass 30 are on the conveying mechanism 11, the mating surface of the first glass 20 faces down and the mating surface of the second glass 30 faces up. After being transferred by the first gripping mechanism 13, the orientation of the mating surfaces of the two glass changes.

[0063] In some processing scenarios, the first glass 20 is the outer sheet of the curved laminated glass 50, and the second glass 30 is the inner sheet of the curved laminated glass 50. The concave surface of the curved outer sheet is the lamination surface, and the convex surface of the curved inner sheet is the lamination surface. During the conveying process on the conveying mechanism 11, both the outer and inner sheets have their convex surfaces facing upwards, exhibiting high consistency in posture, which facilitates image positioning. After the first gripping mechanism 13 transfers and flips the sheets, the outer sheet placed in the lamination device 12 has its convex surface facing downwards and its concave surface facing upwards, and the inner sheet placed in the lamination device 12 also has its convex surface facing downwards and its concave surface facing upwards.

[0064] After the first glass 20 and the second glass 30 are sequentially transferred to the laminating device 12 by the first gripping mechanism 13, the second gripping mechanism 14 first transfers the diaphragm 40 to the laminating surface of the first glass 20, and then places the second glass 30 onto the diaphragm 40 to complete the laminating process. The orientation of the second glass 30 does not change during the process of placing the second glass 30 onto the first glass 20 by the second gripping mechanism 14.

[0065] The laminated glass assembly system 10 uses a conveying mechanism 11 to transport the first glass 20 and the second glass 30, and then combines a first gripping mechanism 13 to grip and flip the two types of glass respectively, reducing the complexity of the entire system.

[0066] Furthermore, such as Figure 1 and Figure 2 As shown, a visual positioning unit 15 can also be provided upstream of the first gripping mechanism 13 to acquire the position information of the first glass 20 and the second glass 30. The visual positioning unit 15 is electrically connected to the first gripping mechanism 13, and the first gripping mechanism 13 can accurately grip the first glass 20 and the second glass 30 based on the position information fed back by the visual positioning unit 15.

[0067] In some embodiments, this application also provides a second gripping mechanism 14 for gripping the membrane 40. For example... Figures 3 to 8As shown, the second gripping mechanism 14 includes a first gripping head 141 and a second gripping head 142, which are used to grip two different parts of the diaphragm 40. The surface of the first gripping head 141 that contacts the diaphragm 40 is the first positioning surface 1411. The surface of the second gripping head 142 that contacts the diaphragm 40 is the second positioning surface 1421. The first gripping head 141 and the second gripping head 142 are movably coupled, resulting in a first state and a second state between them. In the first state, the angle between the first positioning surface 1411 and the second positioning surface 1421 is α1, and in the second state, the angle between the first positioning surface 1411 and the second positioning surface 1421 is α2, and α1 and α2 are not equal. In other words, the angle between the first positioning surface 1411 and the second positioning surface 1421 is unequal in the two different states. The first positioning surface 1411 is parallel to the portion of the diaphragm 40 gripped by the first gripping head 141, and the second positioning surface 1421 is parallel to the portion of the diaphragm 40 gripped by the second gripping head 142. Therefore, the included angle between the two portions of the diaphragm 40 is different in the first and second states.

[0068] Specifically in some embodiments, such as Figure 5 and Figure 6 As shown, in the first state, the included angle α1 between the first positioning surface 1411 and the second positioning surface 1421 is 180°, in other words, in the first state, all parts of the diaphragm 40 are located on a single plane. Figure 7 and Figure 8 As shown, in the second state, the included angle α2 between the first positioning surface 1411 and the second positioning surface 1421 is less than 180°. Compared with the shape of the diaphragm 40 in the first state, the two parts of the diaphragm 40 are bent in the second state.

[0069] The first glass 20 is the outer pane of the curved laminated glass 50. When this outer pane is in the laminating device 12, its concave surface faces upward. The second gripping mechanism 14 is used to place the diaphragm 40 on the concave surface of this outer pane. After the second gripping mechanism 14 is adjusted to the second state, it presses the bent portion in the middle of the diaphragm 40 to the middle position of the concave surface of the outer pane. Then, the first gripping head 141 and the second gripping head 142 release the outer edge of the diaphragm 40, so that the diaphragm 40 is precisely attached to the concave surface of the first glass 20.

[0070] Furthermore, the distance between any point on the first positioning surface 1411 and any point on the second positioning surface 1421 is equal in both the first and second states. This can be understood as the distance between any point on the first positioning surface 1411 and any point on the second positioning surface 1421 remaining unchanged regardless of whether the first gripping head 141 and the second gripping head 142 are in the first or second state. Therefore, the diaphragm 40, gripped at different locations by the first gripping head 141 and the second gripping head 142 respectively, will not be stretched or deformed when bent.

[0071] In summary, the second gripping mechanism 14 is first in the first state, gripping and fixing the diaphragm 40 with the first positioning surface 1411 and the second positioning surface 1421 on the same plane, and then switches to the second state to bend the diaphragm 40, and then places the bent diaphragm 40 on the first glass 20.

[0072] After the second gripping mechanism 14 places the diaphragm 40 onto the first glass 20, it can grip the second glass 30 in the first state or in the second state.

[0073] Specifically, the first gripper head 141 and the second gripper head 142 can achieve the above-mentioned cooperative relationship through a linkage mechanism, so that the first gripper head 141 and the second gripper head 142 can exist in the above-mentioned first state and second state.

[0074] In some embodiments, the aforementioned active mating relationship combines rotation and translation. For example, as... Figures 5 to 8 As shown, the first gripping head 141 and the second gripping head 142 can rotate relative to each other, and the axis of rotation is parallel to both the first positioning surface 1411 and the second positioning surface 1421. The first gripping head 141 and the second gripping head 142 can move relative to each other, and the direction of movement intersects the axis of rotation between them.

[0075] The first gripping head 141 rotates relative to the second gripping head 142 about the aforementioned axis, thereby changing the angle between the first positioning surface 1411 and the second positioning surface 1421. While rotating, the first gripping head 141 and the second gripping head 142 also move relative to each other, and the direction of movement intersects with the aforementioned axis. As a result, the distance between any point on the first positioning surface 1411 and any point on the second positioning surface 1421 remains unchanged during this process, and the diaphragm 40 is not stretched or deformed.

[0076] The relative rotation and relative movement between the first gripping head 141 and the second gripping head 142 can be achieved through a linkage mechanism between them, and no specific restrictions are imposed here.

[0077] Specifically in some embodiments, such as Figures 5 to 8As shown, the first gripping head 141 and the second gripping head 142 are rotatably engaged by a first rotating shaft 143, and both the first positioning surface 1411 and the second positioning surface 1421 are parallel to the axial direction of the first rotating shaft 143. The first rotating shaft 143 is slidable relative to the first gripping head 141 and / or the second gripping head 142, and the sliding direction is perpendicular to the axial direction of the first rotating shaft 143.

[0078] While the first gripping head 141 and the second gripping head 142 rotate about the axis of the first rotating shaft 143, the first rotating shaft 143 moves relative to the first gripping head 141 and / or the second gripping head 142, so that the diaphragm 40 is not stretched or deformed while bending the diaphragm 40.

[0079] For example, the first rotating shaft 143 is fixedly connected to the first gripping head 141, and the second gripping head 142 is provided with a strip-shaped slot for the first rotating shaft 143 to be inserted. The first rotating shaft 143 can rotate in the strip-shaped slot and can move along the length direction of the strip-shaped slot. The length direction of the strip-shaped slot is perpendicular to the axial direction of the first rotating shaft 143.

[0080] Alternatively, in one embodiment, such as Figures 5 to 8 As shown, the second gripper head 142 is provided with a first slide rail 146, and a first slider 147 is slidably fitted on the first slide rail 146. The sliding direction of the first slider 147 on the first slide rail 146 is perpendicular to the axis of the first rotating shaft 143. The first slider 147 is rotatably fitted with the first gripper head 141 through the first rotating shaft 143.

[0081] While the first gripping head 141 and the first slider 147 rotate relative to each other, the first slider 147 can slide on the first slide rail 146. Ultimately, this allows the first gripping head 141 and the second gripping head 142 to rotate and move relative to each other.

[0082] Furthermore, such as Figures 5 to 8 As shown, the second gripping head 142 is also provided with a guide member 148, and the guide member 148 is provided with a guide groove 1481. The first gripping head 141 is also provided with a guide wheel 149, which is slidably mounted in the guide groove 1481. The guide wheel 149 is not located on the axis of the first rotating shaft 143, and the guide wheel 149 is spaced apart from the first rotating shaft 143. The guiding direction of the guide groove 1481 is perpendicular to the axial direction of the first rotating shaft 143, and the guiding direction of the guide groove 1481 intersects with the sliding direction of the first slider 147 on the first slide rail 146.

[0083] Under the guidance of the guide groove 1481, when the first gripper head 141 rotates relative to the second gripper head 142, the guide wheel 149 on the first gripper head 141 can only slide in the guide groove 1481, so that the first gripper head 141 can only slide relative to the second gripper head 142 at the same time.

[0084] like Figure 3 and Figure 4 As shown, in some embodiments, both the first gripping head 141 and the second gripping head 142 include a support 144 and a plurality of suction cups 145 disposed on the support. The suction surfaces of the plurality of suction cups 145 included in the first gripping head 141 constitute a first positioning surface 1411. The suction surfaces of the plurality of suction cups 145 included in the second gripping head 142 constitute a second positioning surface 1421. The two supports 144 are movably engaged, allowing the first gripping head 141 and the second gripping head 142 to exist in a first state and a second state.

[0085] The first gripping head 141 includes a plurality of suction cups 145 which are adsorbed and fixed to a part of the diaphragm 40, and the second gripping head 142 includes a plurality of suction cups 145 which are adsorbed and fixed to another part of the diaphragm 40. When the two supports 144 move relative to each other, the corresponding suction cups 145 move relative to each other.

[0086] In one embodiment, the two supports 144 are rotatably engaged by the aforementioned first rotating shaft 143, which is slidable relative to at least one support 144, and the sliding direction is perpendicular to the axis of the first rotating shaft 143.

[0087] More specifically, the support 144 of the second gripping head 142 is provided with the aforementioned first slide rail 146, and the first slide rail 146 is rotatably engaged with the support 144 of the second gripping head 142 via a first rotating shaft 143. The support 144 of the second gripping head 142 is provided with the aforementioned guide member 148, and the support 144 of the first gripping head 141 is provided with the aforementioned guide wheel 149.

[0088] Furthermore, in some embodiments of this application, a conveying mechanism 11 is provided, which can be the conveying mechanism 11 in the aforementioned laminated glass bonding system 10. For example... Figure 1 , Figure 2 , Figure 9 and Figure 10 As shown, the conveying mechanism 11 includes a first conveying section 111 and a second conveying section 112. The second conveying section 112 is located at the film turning starting station, and the first conveying section 111 is located upstream of the second conveying section 112. The second conveying section 112 includes a first sub-conveyor section 1121 and a second sub-conveyor section 1122. The first sub-conveyor section 1121 is located between the first conveying section 111 and the second sub-conveyor section 1122.

[0089] like Figure 9 and Figure 10 As shown, the first sub-transfer segment 1121 and the second sub-transfer segment 1122 can move relative to each other in the transport direction and can move to a state where they are spaced apart.

[0090] Alternatively, the first sub-transfer segment 1121 may be retractable in the transport direction, allowing it to be spaced apart from the second sub-transfer segment 1122.

[0091] Alternatively, the second sub-transfer segment 1122 may be retractable in the transport direction, allowing it to be spaced apart from the first sub-transfer segment 1121.

[0092] As mentioned earlier, the first glass 20 can be the outer pane of the curved laminated glass 50, and the second glass 30 can be the inner pane of the curved laminated glass 50. During transport on the conveying mechanism 11, both the first glass 20 and the second glass 30 have their convex surfaces facing upwards. At the flipping start position, the first gripping mechanism 13 needs to grip the first glass 20 and the second glass 30 sequentially. At the flipping start position, the mating surface of the first glass 20 is the concave surface facing downwards. The first gripping mechanism 13 can directly act on the convex surface of the first glass 20 from above, thereby transferring the first glass 20 to the mating device 12. When placed in the mating device 12, the concave surface of the first glass 20 faces upwards. During this process, the first gripping mechanism 13 does not need to touch the mating surface of the first glass 20.

[0093] However, at the starting position of the flipping process, the lamination surface of the second glass 30 is the convex surface facing upwards. During the transfer process, it is necessary to avoid touching the lamination surface as much as possible. Therefore, the first sub-transfer section 1121 and the second sub-transfer section 1122 need to switch to a state of separation between them to provide space for the first gripping mechanism 13. The first gripping mechanism 13 passes through the gap space 1126 between the two sub-transfer sections from bottom to top and acts on the concave surface of the second glass 30, thereby transferring the second glass 30 into the lamination device 12. When placed in the lamination device 12, the concave surface of the second glass 30 is facing upwards.

[0094] This can be understood as follows: when the first gripping mechanism 13 transfers the first glass 20, the two sub-transfer sections are in direct contact; when the first gripping mechanism 13 transfers the second glass 30, the two sub-transfer sections are in a spaced-out state.

[0095] like Figure 14 As shown, the first gripping mechanism 13 includes a robotic arm, the hand of which is provided with a suction cup 145 for adsorbing and fixing the first glass 20 and the second glass 30.

[0096] like Figure 9 and Figure 10As shown, a support frame 113 is provided below the second conveying section 112. A notch 1131 is provided on this support frame 113 at a location below the second sub-conveyor section 1122. The notch 1131 originates below the junction of the first sub-conveyor section 1121 and the second sub-conveyor section 1122, and extends through the support frame 113 along the conveying direction of the second sub-conveyor section 1122. The notch 1131 also extends through at least one side of the support frame 113 in a direction perpendicular to the conveying direction.

[0097] The hand of the first gripping mechanism 13 moves from outside the support frame 113 along the notch 1131 to below the space between the two sub-transfer sections 1126 and grips the second glass 30 on the second conveyor belt 112. Then it can pass directly through the space between the two sub-transfer sections and move above the second conveyor belt 112.

[0098] When the first glass 20 and the second glass 30 move and are conveyed on the second conveying section 112, the two sub-conveying sections are in direct contact to ensure smoother conveying. After the second glass 30 is in place, the two sub-conveying sections switch to an intermittent state.

[0099] Specifically, such as Figure 9 and Figure 10 As shown, in one embodiment, the first sub-transmission section 1121 includes a telescopic conveyor belt 1123, which is disposed on a sliding module. The sliding module includes a second slide rail and a second slider that slides on the second slide rail. The guiding direction of the second slide rail is parallel to the conveying direction. One end of the telescopic conveyor belt 1123 near the first transmission section 111 is fixed relative to the second slide rail, and one end of the telescopic conveyor belt 1123 near the second sub-transmission section 1122 is connected to the second slider.

[0100] The telescopic conveyor belt 1123 can be adjusted by sliding the second slider on the second slide rail, thereby enabling the telescopic conveyor belt 1123 to move to a state that is spaced apart from the second sub-conveyor section 1122.

[0101] Specifically, a telescopic drive component such as a cylinder can be installed between the second slider and the second slide rail to drive the second slider to move on the second slide rail.

[0102] In this application, the telescopic conveyor belt 1123 refers to a conveyor belt whose length can be varied in the conveying direction. This includes conveyor belts made of elastic materials, utilizing the elasticity of the material to stretch and extend to meet the aforementioned requirements; and conveyor belts whose length in the conveying direction can be adjusted by winding them onto a reel. For example, one end of the conveyor belt near the second sub-conveying segment 1122 is wound onto a reel. The axis of this reel is perpendicular to the conveying direction of the conveyor belt. This reel is mounted on a second slider, and the reel can rotate relative to the second slider to accommodate the movement of the second slider. When the second slider moves towards the second sub-conveying segment 1122, this reel rotates in a first direction to release the wound conveyor belt. When the second slider moves towards the first conveying segment 111, this reel rotates in the opposite direction to the first direction to wind the conveyor belt onto the reel.

[0103] like Figure 9 and Figure 10 As shown, the second sub-transmission section 1122 also includes a first conveyor belt 1124. The first conveyor belt 1124 is arranged along the conveying direction of the conveying mechanism 11. The telescopic conveyor belt 1123 changes its length in the conveying direction, so that it can switch between a state of contact with the first conveyor belt 1124 and a state of being spaced apart from the first conveyor belt 1124.

[0104] In such Figure 9 and Figure 10 In the embodiment shown, the second sub-transfer segment 1122 includes two side-by-side first conveyor belts 1124, and the first sub-transfer segment 1121 includes two side-by-side telescopic conveyor belts 1123.

[0105] Furthermore, in some embodiments, a ramp 1125 is provided at one end of the first sub-transfer segment 1121 near the first transfer segment 111, and the edge of the ramp 1125 that aligns with the first transfer segment 111 has a lower horizontal height, so as to facilitate the transition of the glass on the first transfer segment 111 to the first sub-transfer segment 1121.

[0106] like Figures 11 to 13 As shown, in some embodiments, the laminating device 12 includes a servo module 121. The laminating device 12 is provided with a first placement position 122, a second placement position 123 and a laminating position 124. The servo module 121 is arranged between the first placement position 122 and the laminating position 124 for conveying the glass located at the first placement position 122 to the laminating position 124.

[0107] The first gripping mechanism 13 has at least two operating modes. In one operating mode, the first gripping mechanism 13 can transfer the first glass 20, which is conveyed to the flipping start station, to the servo module 121 located at the first placement station 122, and flip the first glass 20 during the transfer process. The first glass 20, which has been transferred to the first placement station 122, is then conveyed by the servo module 121 to the lamination station 124. In another operating mode, the first gripping mechanism 13 can transfer the second glass 30, which is conveyed to the flipping start station, to the second placement station 123, and flip the second glass 30 during the transfer process.

[0108] The second gripping mechanism 14 can place the diaphragm 40 onto the bonding surface of the first glass 20 located at the bonding position 124, and then place the second glass 30 at the second placement position 123 onto the diaphragm 40, so that the first glass 20, the diaphragm 40 and the second glass 30 are bonded together.

[0109] Furthermore, in some other embodiments, such as Figure 1 and Figure 2 As shown, the laminated glass bonding system 10 also includes a point heating unit, which is used to heat the laminated glass in the bonding device 12.

[0110] Specifically, such as Figure 15 and Figure 16 As shown, the point heating unit includes a point heating robot 16, the hand of which is equipped with a point heating element 161 and a stacking difference measuring instrument 162. The point heating element 161 is used to point heat the laminated glass in the laminating device 12. In one embodiment, the point heating element 161 includes an electric heating rod for point heating the glass. The stacking difference measuring instrument 162 is used to measure the stacking difference accuracy of the laminated glass 50 after point heating. Specifically, the stacking difference measuring instrument 162 can be a three-dimensional profile measuring instrument B.

[0111] The laminated glass bonding system 10 also includes a three-dimensional profile measuring instrument A, which is used to measure the relative positions of the profiles of the first glass 20, the film 40 and the second glass 30 after the point heating unit is heated. The three-dimensional profile measuring instrument A is electrically connected to the second gripping mechanism 14.

[0112] When the detection result of the three-dimensional profile measuring instrument B shows that there is an overlap difference in the laminated glass 50, the three-dimensional profile measuring instrument A can detect the relative position of the contours of the first glass 20, the diaphragm 40 and the second glass 30, and transmit the error values ​​of the three to the second gripping mechanism 14 or the control unit. The second gripping mechanism 14 automatically compensates and adjusts according to the aforementioned error values ​​of the three to eliminate the lamination error.

[0113] Furthermore, in yet another embodiment, a method for laminating laminated glass is provided, comprising the following steps:

[0114] The first glass and the second glass are sequentially conveyed to the flipping start station along the same conveying direction, with the lamination surface of the first glass facing down and the lamination surface of the second glass facing up during this conveying process;

[0115] The first glass and the second glass at the flipping starting station are transferred to the laminating device in sequence. During the transfer, both the first glass and the second glass are flipped so that the laminating surface of the first glass is facing up and the laminating surface of the second glass is facing down.

[0116] First, the diaphragm is transferred to the first glass on the laminating device, and then the second glass on the laminating device is placed on the diaphragm.

[0117] The first and second glass panes are sequentially conveyed along the same conveying direction to the flipping starting station and then transferred to the laminating device. During the transfer, both the first and second glass panes flip to change the orientation of their laminating surfaces. Then, a diaphragm is placed on the first glass pane, and the second glass pane is placed on the diaphragm, completing the laminating process. This eliminates the need to assign separate conveying directions for the first and second glass panes, simplifying the laminating process.

[0118] Specifically, the laminated glass assembly method can be implemented using the laminated glass assembly system described in any of the above embodiments.

[0119] In one embodiment, the laminated glass bonding method includes the following steps:

[0120] The outer and inner glass sheets are sequentially conveyed to the flipping start station along the same conveying direction, with the concave side of the outer glass sheet facing down and the convex side of the inner glass sheet facing up during this conveying process.

[0121] The outer and inner glass sheets at the flipping start station are transferred sequentially to the laminating device. During the transfer, both the outer and inner glass sheets are flipped so that the concave side of the outer glass sheet placed on the laminating device faces upward and the convex side of the inner glass sheet faces downward.

[0122] First, transfer the diaphragm to the outer glass of the laminating device, and then place the inner glass of the laminating device onto the diaphragm.

[0123] During the conveying process along the same conveying direction, both the outer and inner glass sheets have their convex surfaces facing upwards, and their postures are relatively consistent.

[0124] Furthermore, in some embodiments, transferring the diaphragm onto the first glass of the laminating device specifically includes the following steps:

[0125] Step 1: Use the gripping heads on the second gripping mechanism to grip different parts of the diaphragm. Some of the gripping heads have a first positioning surface for contacting the diaphragm, and some of the gripping heads have a second positioning surface for contacting the diaphragm. At this time, the first positioning surface and the second positioning surface that the gripping head contacts different parts of the diaphragm are on the same horizontal plane.

[0126] Step 2: Control the relative movement between each gripping head to form an angle between the first positioning surface and the second positioning surface, and to bend the diaphragm.

[0127] The second gripping mechanism first places the middle part of the bent diaphragm on the first glass, and then releases the diaphragm and gradually attaches the outer periphery of the diaphragm to the first glass.

[0128] Furthermore, in some embodiments, the distance between any point on the first positioning surface and any point on the second positioning surface remains equal before and after bending. This prevents the diaphragm from being stretched during bending, further avoiding diaphragm contraction and deformation after the gripping mechanism releases the diaphragm.

[0129] Specifically, in one embodiment, in step two, the diaphragm is bent to form a V-shape.
