[0034] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0035] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0036] A glass assembly (i.e., a framed glass structure) consists of glass panels and a mounting frame. In a curved glass assembly, the glass panels can be single-curved or double-curved. The mounting frame is the main structure that fixes and supports the glass panels, ensuring the stability and safety of the glass curtain wall. The commonly used material for mounting frames is aluminum alloy, which has excellent mechanical properties and corrosion resistance. The mounting frame is connected to the main structure through beams and columns, forming a stable support system. Simultaneously, the mounting frame and glass panels are fixed and sealed using structural adhesive or other connection methods.

[0037] Existing methods for bending glass components mainly include hot bending and cold bending. Hot bending involves bending the glass in a molten state using custom molds or rollers, resulting in high energy consumption, high costs, and manufacturing difficulties. Furthermore, hot bending affects the optical imaging quality of the glass. Cold bending, on the other hand, typically involves placing the glass sheet on a mounting frame and bending it at room temperature by applying forced displacement. This method offers greater flexibility and can be completed in a factory or on-site, resulting in high installation efficiency. However, cold bending incurs permanent stresses on the glass's interior and surface, the magnitude and distribution of which significantly impact the glass's strength and safety. Currently, there are no standards or specifications for cold bending of glass, either domestically or internationally.

[0038] This application achieves better bending effect of the glass component by first bending the mounting frame to a preset curved shape, then fitting a portion of it under its own weight, and then further pressing and shaping it. The process is simple, efficient, and low-cost.

[0039] To address the problems of the prior art, this application provides a glass assembly cold bending apparatus. The glass assembly cold bending apparatus provided in this application will be described below.

[0040] Figure 1 This application shows a schematic diagram of the overall structure of a glass assembly cold bending device provided in some embodiments; Figure 2 This paper shows one of the structural schematic diagrams of a cold bending assembly 100 provided in some embodiments of this application; Figure 3 This is shown as a second schematic diagram of the structure of a cold bending assembly 100 provided in some embodiments of this application.

[0041] like Figures 1 to 3As shown in the embodiment of this application, a glass assembly cold bending device is provided. The glass assembly includes a curved mounting frame and a glass plate connected to the mounting frame. It includes a mounting platform 200 and cold bending assemblies 100. Multiple cold bending assemblies 100 are mounted on the mounting platform 200 and enclose a cold bending area 201 for placing the glass assembly. Each cold bending assembly 100 includes a support mechanism 120 and a loading mechanism 110 mounted on the side of the support mechanism 120 facing away from the mounting platform 200. The support mechanism 120 includes a support for the mounting frame. The support 121 and a plurality of positioning members 122 are installed on the side of the support 121 facing away from the mounting platform 200. The plurality of positioning members 122 form a limiting area 123 along the depth direction of the cold bending assembly 100 for limiting the mounting frame. The loading mechanism 110 includes a first working position and a second working position. In the first working position, the loading mechanism 110 and the support 121 are arranged opposite to each other along the height direction of the cold bending assembly 100. In the second working position, the loading mechanism 110 and the support 121 are staggered to avoid the cold bending area 201.

[0042] Specifically, the mounting platform 200 serves as the basic support platform for the entire glass assembly cold bending device, used to install and fix the cold bending assembly 100, ensuring stability and safety during the cold bending process. The mounting platform 200 should have sufficient rigidity and stability to meet the deformation precision control requirements generated during the cold bending process.

[0043] Multiple cold-bending components 100 are mounted on the mounting platform 200, forming a specific cold-bending area 201 for placing glass components to be processed. This facilitates simultaneous multi-station operation and improves production efficiency. The positions of the multiple cold-bending components 100 on the mounting platform 200 depend on the size and shape of the glass component, with the cold-bending components 100 spaced apart along the sides of the glass component. For example, if the overall shape of the glass component is rectangular, the cold-bending components 100 can be spaced apart along two or all four sides of the rectangle, so that at least two long sides of the mounting frame rest on the support mechanism 120 of the cold-bending components 100. Alternatively, if the overall shape of the glass component is triangular, the cold-bending components 100 can be spaced apart along the sides of the triangle, so that each side of the mounting frame rests on the support mechanism 120 of the cold-bending components 100. The multiple cold-bending components 100 are detachably connected to the mounting platform 200, allowing the glass component cold-bending device to cold-bend glass components of different shapes and sizes, thus improving the adaptability of the glass component cold-bending device.

[0044] The cold bending assembly 100 includes a support mechanism 120 and a loading mechanism 110 installed on the side of the support mechanism 120 facing away from the mounting platform 200. That is, the support mechanism 120 is connected to the mounting platform 200, the loading mechanism 110 is connected to the support mechanism 120, the loading mechanism 110 is positioned above the support mechanism 120, and the glass assembly is placed between the support mechanism 120 and the loading mechanism 110. The loading mechanism 110 is movably connected to the support mechanism 120, including a first working position and a second working position. In the first working position, the loading mechanism 110 and the support mechanism 120 are arranged opposite each other along the height direction of the cold bending assembly 100. That is, the support mechanism 120 supports the glass assembly, and the loading mechanism 110 applies a loading force to the glass assembly from top to bottom, so that the glass plate fits into the mounting frame. In the second working position, the loading mechanism 110 and the support mechanism 120 are staggered to avoid the cold bending area 201. For example, before the glass assembly is placed on the support mechanism 120, the loading mechanism 110 is switched from the first working position to the second working position, so that the glass assembly can be hoisted from top to bottom onto the support mechanism 120. After the glass assembly is cold bent, the loading mechanism 110 is switched from the first working position to the second working position, so that the glass assembly can be hoisted from top to bottom and removed from the glass assembly cold bending device.

[0045] The support mechanism 120 includes a support member 121 supporting the mounting frame and multiple positioning members 122 installed on the side of the support member 121 facing away from the mounting platform 200. The multiple positioning members 122 form a limiting region 123 along the depth direction of the cold-bending assembly 100, used to limit the mounting frame. The support member 121 directly supports the mounting frame, ensuring its stable posture during cold bending. The limiting region 123 formed by the multiple positioning members 122 precisely limits the mounting frame, preventing displacement or deformation during cold bending. Specifically, some of the positioning members 122 are placed outside the mounting frame, contacting the outer edge of the mounting frame, while others are placed inside the mounting frame, contacting the inner edge of the mounting frame. In other words, the limiting region 123 is set along the length direction of a single frame of the mounting frame, thereby limiting the width direction of the single frame of the mounting frame, ensuring the stability and accuracy of the mounting frame during cold bending, and reducing deformation of the single frame of the mounting frame inwards and outwards.

[0046] In the first working position, the loading mechanism 110 and the support member 121 are arranged opposite each other along the height direction of the cold bending assembly 100, that is, the loading mechanism 110 and the support member 121 are at 0 degrees. The loading mechanism 110 presses down on the glass plate placed on the support member 121 and cut into the limiting area 123 to apply a loading force, so that the glass plate is tightly fitted to the frame of the mounting frame. In the second working position, the loading mechanism 110 and the support member 121 are staggered to avoid the cold bending area 201. For example, the loading mechanism 110 and the support member 121 are arranged at 180 degrees or 90 degrees.

[0047] Continue to refer to Figure 1 In one embodiment of this application, in order to achieve flexible installation of the installation platform 200 and the cold bending component 100, the installation platform 200 includes first installation holes 202 arranged at row and column intervals, and the support mechanism 120 is provided with a second installation hole 203 on the side opposite to the loading mechanism 110. The support mechanism 120 and the installation platform 200 are detachably connected through the first installation hole 202 and the second installation hole 203.

[0048] The first mounting holes 202, spaced at intervals, provide mounting points for the cold-bending assembly 100 to accommodate glass assemblies of different sizes and shapes, improving the flexibility of installation. A second mounting hole 203 is provided on the side of the support mechanism 120 that contacts the mounting platform 200. The diameter and spacing of the second mounting hole 203 correspond to those of the first mounting holes 202. A detachable connection between the support mechanism 120 and the mounting platform 200 is achieved using bolts or other fasteners. During installation, the fasteners are passed through the first mounting holes 202 and the second mounting holes 203 and tightened to secure the support mechanism 120. When it is necessary to disassemble or adjust the support mechanism 120, simply loosening the fasteners is sufficient.

[0049] The detachable connection allows for easy installation and removal of the support mechanism 120, facilitating maintenance and replacement. When the cold bending unit needs to accommodate glass assemblies of different shapes and sizes, the support mechanism 120 can be easily adjusted or replaced. If a component of the support mechanism 120 or the mounting platform 200 malfunctions or is damaged, that component can be disassembled and replaced individually without replacing the entire unit, thus reducing maintenance costs and time, and simplifying maintenance. The modular design enabled by the detachable connection makes the cold bending unit easier to assemble and transport. Individual components can be manufactured and stored independently, and then assembled into a complete unit when needed.

[0050] Figure 4 This paper shows an overall structural schematic diagram of the adapter 140 provided in some embodiments of this application;

[0051] Figure 5 A front view of an adapter 140 provided in some embodiments of this application is shown.

[0052] Furthermore, such as Figure 4 and Figure 5 As shown in a specific embodiment of this application, in order to achieve fine-tuning between the cold bending assembly 100 and the mounting platform 200, the cold bending assembly 100 further includes an adapter 140. The adapter 140 includes a first base plate 141 and a second base plate 143 arranged opposite to each other along the height direction of the cold bending assembly 100. The first base plate 141 has a plurality of first adjustment elongated holes 142 along the length direction of the adapter 140, and the adapter 140 is detachably connected to the support mechanism 120 through the first adjustment elongated holes 142. The second base plate 143 has a plurality of second adjustment elongated holes 144 along the width direction of the adapter 140, and the adapter 140 is detachably connected to the mounting platform 200 through the second adjustment elongated holes 144.

[0053] The adapter 140 includes a first base plate 141 and a second base plate 143. A connecting plate 145 and a reinforcing plate are connected between the first base plate 141 and the second base plate 143. The first base plate 141 and the second base plate 143 are arranged opposite each other on the upper and lower surfaces of the connecting plate 145 along the height direction of the cold bending assembly 100. A fourth reinforcing plate 147 is connected between the first base plate 141 and the connecting plate 145, and a fifth reinforcing plate 146 is connected between the second base plate 143 and the connecting plate 145, which improves the stability of the adapter 140.

[0054] Multiple first adjustment elongated holes 142 are formed along the length of the first base plate 141. The first adjustment elongated holes 142 detachably connect the adapter 140 to the support mechanism 120 via bolts, pins, or other fasteners. Because they are first adjustment elongated holes 142, the relative position between the adapter 140 and the support mechanism 120 can be adjusted within a certain range to accommodate different installation requirements or adjustment precision. The lengths of the multiple first adjustment elongated holes 142 can be different. No first adjustment elongated holes 142 are formed in the area where the support mechanism 120 contacts the first base plate 141, thus ensuring the strength of the first base plate 141. The multiple first adjustment elongated holes 142 can be arranged parallel to each other.

[0055] Multiple second adjustment elongated holes 144 are formed along the width direction of the second base plate 143. These holes 144 allow for a detachable connection between the adapter 140 and the mounting platform 200, and also support positional adjustment within a certain range. This is crucial for ensuring the stability and accuracy of the adapter 140 on the mounting platform 200. The lengths of the multiple second adjustment elongated holes 144 can be different. No first adjustment elongated holes 142 are formed in the area where the connecting plate 145 contacts the second base plate 143, thus ensuring the strength of the second base plate 143. The multiple second adjustment elongated holes 144 can be arranged parallel to each other.

[0056] By opening a first adjusting elongated hole 142 and a second adjusting elongated hole 144 perpendicular to the adjustment direction, the adapter 140 is able to make fine adjustments in the length and width directions, thus realizing the connection between the cold bending assembly 100 and the mounting platform 200. The adapter 140 not only acts as a bridge between the cold bending assembly 100 and the mounting platform 200, but also allows for flexible adjustment according to specific installation environments or requirements. This design greatly increases the applicability and installation convenience of the cold bending assembly 100. The detachable connection between the adapter 140 and the cold bending assembly 100 and the mounting platform 200 makes maintenance or component replacement easier. This reduces maintenance costs and improves work efficiency.

[0057] The following describes the support mechanism 120 according to an embodiment of this application. Figure 6 A partial structural schematic diagram of the support mechanism 120 provided in some embodiments of this application is shown.

[0058] like Figure 2 and Figure 6 As shown, in other embodiments of this application, the support mechanism 120 includes a first lifting module 126 arranged along the height direction of the cold bending assembly 100. The first lifting module 126 is connected to the support member 121 and is used to control that the support member 121 of each cold bending assembly 100 is in contact with the mounting frame.

[0059] The first lifting module 126 is connected to the support member 121, driving the support member 121 to move linearly along the height direction of the cold bending assembly 100, thereby adjusting the distance of the support member 121 relative to the mounting platform 200, so that the support member 121 contacts the mounting frame. Since the mounting frame has curvature, the distance between the mounting frame and the mounting platform 200 may vary at different points. To better ensure that the support member 121 fits snugly against the mounting frame, the first lifting module 126 enables the support member 121 to be adjustable along the height direction.

[0060] Specifically, such as Figure 6As shown, the first lifting module 126 includes a second handwheel 1204, a belt drive assembly 1205, a drive gear set 1203, a first lead screw 1202, and a second lead screw nut assembly 1201. The second handwheel 1204 is shaft-driven to the belt drive assembly 1205. The belt drive assembly is driven to the input end of the drive gear set 1203. The output end of the drive gear set 1203 is connected to the first lead screw 1202. The first lead screw 1202 is through-fitted to the second lead screw nut assembly 1201. The second lead screw nut assembly 1201 is fixedly connected to the support member 121. The rotation of the second handwheel 1204 drives the first lead screw 1202 to rotate via the belt drive assembly 1205 and the drive gear set 1203. The rotation of the first lead screw 1202 drives the second lead screw nut assembly 1201 to move up and down along the first lead screw 1202, thereby driving the support member 121 to move up and down along the first lead screw 1202. The first lead screw 1202 is arranged along the height direction of the cold bending assembly 100. The input and output ends of the drive gear set 1203 can be arranged vertically along the axis or at an angle, such as 90 degrees, to facilitate the rotation of the second handwheel 1204. The belt drive assembly 1205 can extend the distance between the second handwheel 1204 and the drive gear set 1203, thereby raising the second handwheel 1204 for easier operation. The second handwheel 1204 and the support 121 are located on opposite radial sides of the first lead screw 1202.

[0061] Of course, in other embodiments of this application, a motor can be used to drive the drive gear set 1203 to rotate, thereby realizing the lifting and lowering movement of the support member 121. In addition, the first lifting module 126 can also be a hydraulic cylinder or a pneumatic cylinder structure.

[0063] like Figure 3 , Figure 6 and Figure 7 As shown, in an optional embodiment of this application, the support mechanism 120 further includes a support mounting frame 127. The support mounting frame 127 has a guide rail 129 along its height direction. The first lifting module 126 is slidably connected to the guide rail 129 and extends through the support mounting frame 127 along its depth direction, connecting to the support member 121. The first lifting module 126 and the support member 121 are positioned on both sides of the support mounting frame 127, which can better balance the weight of the mounting frame on the support member 121, maintain the balance of the cold bending assembly 100, and improve the stability of the cold bending assembly 100.

[0064] The support mounting frame 127 is provided with a guide rail 129 along the height direction. The guide rail 129 is parallel to the first lead screw 1202. The first lifting module 126 is slidably connected to the guide rail 129, that is, the second lead screw assembly 1201 is slidably connected to the guide rail 129. The second lead screw assembly 1201 includes a lead screw sleeve, an extension plate, and a slider plate. The lead screw sleeve is fitted with the first lead screw 1202. One end of the extension plate is fixedly connected to the lead screw sleeve, and the other end is fixedly connected to the slider plate. The side of the slider plate near the lead screw sleeve is slidably engaged with the guide rail 129, and the side facing away from the lead screw sleeve is fixedly connected to the support member 121. The drive gear set 1203 is fixedly connected to the support mounting frame 127. The support mounting frame 127 provides a stable connection for the first lifting module 126, and the guide rail 129 guides the lifting movement of the first lifting module 126, so that the first lifting module 126 stably lifts and lowers the support member 121.

[0065] Among them, such as Figure 7 As shown, in a specific embodiment of this application, the support mounting frame 127 includes a second top plate 1210, a second bottom plate 1212, and a connecting column 1211. The second top plate 1210 and the second bottom plate 1212 are arranged opposite to each other along the height direction of the connecting column 1211 and are connected to the connecting column 1211. The connecting column 1211 has a through area 1213 along its thickness direction. The guide rail 129 is installed on opposite sides of the through area 1213 along the height direction of the connecting column 1211. The second lifting module 112 passes through the through area 1213 and is connected to the support plate 124. A third reinforcing plate 1214 is provided between the connecting column 1211 and the second bottom plate 1212. The cross-section of the connecting column 1211 can be rectangular, circular, or other shapes. The first lifting module 126 slides through the through area 1213 and is slidably engaged with the guide rail 129, and is connected to the support member 121.

[0066] The guide rail 129 is installed on the side of the connecting column 1211 facing away from the second handwheel 1204. The drive gear set 1203 is fixedly connected to the second base plate 1212. The second base plate 1212 has a second mounting hole 203, which can be used to connect with the mounting platform 200 or the adapter 140. The end of the second lead screw 1202 facing away from the drive gear set 1203 is connected to the second top plate 1210.

[0067] Continue to refer to Figure 2 and Figure 6 In one optional embodiment of this application, the support member 121 includes a tray 124 and an arc-shaped rubber block 125 installed on the side of the tray 124 facing away from the mounting platform 200. The arc-shaped surface of the arc-shaped rubber block 125 faces away from the tray 124. The positioning member 122 is installed on the side of the tray 124 where the arc-shaped rubber block 125 is located. The arc-shaped rubber block 125 is placed within the limiting area 123.

[0068] An arc-shaped adhesive block 125 is installed on the side of the support plate 124 facing away from the mounting platform 200, with the arc-shaped surface of the adhesive block 125 facing away from the support plate 124. The arc-shaped adhesive block 125 can be bonded or bolted to the support plate 124. The arc-shaped surface of the adhesive block 125 contacts the mounting frame, and the curvature direction of the arc-shaped surface is consistent with the bending direction of the mounting frame, so that the mounting frame fits better on the arc-shaped adhesive block 125. For example, the arc-shaped surface of the adhesive block 125 is a raised surface formed along the extension direction of the frame edge of the mounting frame. The support plate 124 is fixedly connected to the second nut assembly 1201 of the first lifting module 126. The arc-shaped adhesive block 125 can be made of rubber, plastic, or polyurethane to avoid damage to the mounting frame during cold bending loading.

[0069] Multiple positioning elements 122 are installed on one side of the support plate 124 where the arc-shaped rubber block 125 is located. Along the depth direction of the cold bending assembly 100, two sets of positioning elements 122 are included, forming a limiting area 123 between the first and second sets. In one embodiment of this application, the positioning element 122 is a cylindrical structure and is adjustablely connected to the support plate 124. For example, along the depth direction of the cold bending assembly 100, the support plate 124 has a third adjusting elongated hole 1206. The first and second sets of positioning elements 122 are installed within the third adjusting elongated hole 1206. Based on the width of the frame of the mounting frame, the distance between the first and second sets of positioning elements 122 is adjusted so that both sets of positioning elements 122 abut against the mounting frame. The height of the positioning element 122 should be less than the thickness of the mounting frame to avoid interference when the glass plate falls and adheres to the surface of the mounting frame.

[0070] The loading mechanism 110 of this application embodiment will be described below.

[0071] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the loading mechanism 110 includes a loading mounting frame 111 and a second lifting module 112 with a pressure head 113. The loading mounting frame 111 is connected to the side of the support mechanism 120 facing away from the mounting platform 200. The end of the second lifting module 112 opposite to the pressure head 113 is connected to the loading mounting frame 111. The pressure head 113 extends along the height direction of the cold bending assembly 100 toward the limiting area 123.

[0072] The loading mounting bracket 111 is connected to the side of the support mechanism 120 facing away from the mounting platform 200. Placing the loading mechanism 110 above the support mechanism 120 facilitates the second lifting module 112 to apply downward pressure to the glass assembly, making the glass plate fit with the mounting frame, and realizing the cold bending deformation of the glass assembly according to the curvature of the mounting frame.

[0073] The second lifting module 112 has two opposite ends along its length, one end connected to the pressure head 113 and the other end connected to the loading mounting frame 111. The pressure head 113 is used to directly contact the glass plate. The pressure head 113 can be made of rubber, plastic, or polyoxymethylene to avoid damage to the glass plate during cold bending loading. Driven by the second lifting module 112, the pressure head 113 moves up and down along the height direction of the cold bending assembly 100. The pressure head 113 corresponds to the arc-shaped adhesive block 125 of the support 121, thereby better adhering to the mounting frame within the limiting area 123 and the glass plate on the upper surface of the mounting frame.

[0074] Figure 8 This paper shows a schematic diagram of the overall structure of the loading mounting bracket 111 provided in some embodiments of this application; Figure 9 A front view of the loading mounting bracket 111 provided in some embodiments of this application is shown.

[0075] like Figure 2 , Figure 3 and Figure 8 As shown, in some other embodiments of this application, the loading mounting frame 111 includes a support arm 115 and a cantilever 114. The support arm 115 is connected to the support mounting frame 127, and the cantilever 114 is connected to the side of the support arm 115 facing away from the support mounting frame 127 and extends along the depth direction. The support arm 115 and the support mounting frame 127 are movable. In the first working position, one end of the cantilever 114 is connected to the support arm 115, and the other end extends in the direction away from the support arm 115, so that the pressure head 113 of the second lifting module 112 installed on the cantilever 114 and the support member 121 are arranged vertically opposite each other during the cold bending process. The arrangement of the cantilever 114 facilitates the extension of the second lifting module 112 to cooperate with the support member 121 to apply pressure to the glass plate.

[0076] Among them, such as Figure 8 and Figure 9As shown, the loading mounting frame 111 includes a first top plate 1101, a first bottom plate 1103, a first connecting plate 1102, a first reinforcing plate 1104, a second reinforcing plate 1105, and a sealing plate 1109. The first top plate 1101 and the first bottom plate 1103 are placed at both ends of the first connecting plate 1102 along the length direction of the first connecting plate 1102. One end of the first top plate 1101 and the first bottom plate 1103 are connected to the first connecting plate 1102, and the other ends extend in opposite directions. A first reinforcing plate 1104 is connected between a first connecting plate 1102 and a first base plate 1103. A first lifting module 126 is installed on a first top plate 1101. The first top plate 1101 has a lifting hole 1107 for the first lifting module 126 to pass through. A second reinforcing plate 1105 is connected between the first connecting plate 1102 and the first top plate 1101. A sealing plate 1109 is connected to the first top plate 1101 and the second reinforcing plate 1105, and is positioned opposite to the first connecting plate 1102. Multiple first reinforcing plates 1104 are spaced apart along the length of the first base plate 1103, and multiple second reinforcing plates 1105 are spaced apart along the length of the first top plate 1101. The arrangement of the first reinforcing plates 1104 and second reinforcing plates 1105 increases the bending stiffness of the first top plate 1101 and the lateral bending stiffness of the first connecting plate 1102. The arrangement of the sealing plate 1109 further improves the bending stiffness of the first top plate 1101. Figure 7 and 8 As shown, in some embodiments of this application, the loading mounting bracket 111 and the support mounting bracket 127 are connected by a rotating shaft mechanism 130 and a locking mechanism 131 to achieve switching of the loading mechanism 110 between a first working position and a second working position. In the first working position, the locking mechanism 131 is locked to the loading mounting bracket 111 and the support mounting bracket 127, and the pressure head 113 and the support member 121 are arranged opposite each other in the height direction. In the second working position, the locking mechanism 131 is unlocked from the loading mounting bracket 111 and the support mounting bracket 127, and the loading mounting bracket 111 and the support mounting bracket 127 are rotated and misaligned around the rotating shaft mechanism 130.

[0077] For example, the rotating shaft mechanism 130 includes a rotating shaft and a bushing. The bushing is fitted inside the rotating shaft to allow the bushing to rotate around the rotating shaft and avoid obstruction. The rotating shaft is installed on the side of the second top plate 1210 of the support mounting bracket 127 facing away from the connecting column 1211, and the rotating shaft is installed at the center of mass of the second top plate 1210. The bushing is installed on the side of the first bottom plate 1103 of the loading mounting bracket 111 facing away from the support mechanism 120, and the bushing is installed at the center of mass of the first bottom plate 1103. The locking mechanism 131 includes a bolt fastening structure. The second top plate 1210 has a second fastening hole 1216 for connecting to the locking mechanism 131; the first bottom plate 1103 has a first fastening hole 1108 for connecting to the locking mechanism 131; the lifting hole 1107 and the bushing are located on both sides of the thickness direction of the first connecting plate 1102. The bolt fastening structure passes through the first fastening hole 1108 and the second fastening hole 1216 to lock the loading mechanism 110 and the support mechanism 120. Loosening the bolt fastening structure unlocks the mechanism. Of course, the locking mechanism 131 can also be a pin, a snap-fit ​​structure, etc.

[0078] Figure 10 A schematic diagram of the structure of the second lifting module 112 provided in some embodiments of this application is shown.

[0079] like Figure 2 , Figure 3 and Figure 10 As shown, the second lifting module 112 also includes a drive unit 128, a lifting rod 101, and a force sensor 103 and a ball joint 102 arranged along the axial direction of the lifting rod 101. The lifting rod 101 is connected to the loading mounting frame 111 through the drive unit 128. The force sensor 103 and the ball joint 102 are arranged sequentially between the lifting rod 101 and the pressure head 113.

[0080] The drive unit 128 serves as a power source, driving the lifting rod 101 to move up and down. The drive unit 128 can be a motor, hydraulic cylinder, or pneumatic cylinder, depending on the overall design and requirements of the equipment. Motor drives typically offer higher precision and controllability, while hydraulic or pneumatic cylinders may provide greater output force. The lifting rod 101 transmits the linear motion of the drive unit 128 to the pressure head 113, thereby applying cold bending pressure to the glass assembly. The lifting rod 101 should have sufficient rigidity and stability to ensure that it does not bend or deviate when pressure is applied. A force sensor 103 is installed between the lifting rod 101 and the pressure head 113 to monitor and provide feedback on the pressure value applied to the glass assembly in real time. This is crucial for controlling the pressure during the cold bending process, ensuring processing accuracy, and preventing overpressure damage to the glass assembly. The force sensor 103 should have high sensitivity and high accuracy to accurately measure and record pressure data. A ball joint 102 is positioned between the lifting rod 101 and the pressure head 113, below the force sensor 103. The ball joint 102 allows the pressure head 113 to have a certain degree of self-adjustment capability when pressure is applied, in order to adapt to minor unevenness or curvature changes on the surface of the glass assembly. This self-adjustment helps to ensure uniform pressure distribution and improve the cold bending effect. Multiple ball joints 102 can be arranged in parallel, thereby accommodating surface variations of large-curvature curved glass panels.

[0081] In an optional embodiment of this application, the drive component 128 is mounted on the cantilever 114 and includes a first handwheel 106, a drive shaft assembly 105, and a first lead screw assembly 104 arranged sequentially along the length of the cantilever 114. The first handwheel 106 is connected to the input end of the first lead screw assembly 104 via the drive shaft assembly 105. The lifting rod 101 passes through the cantilever 114 at one end facing away from the support arm 115 and is connected to the output end of the first lead screw assembly 104. The lifting rod 101 is a lead screw and cooperates with the first lead screw assembly 104. The first lead screw assembly 104 includes a vertically oriented input end and an output end. The input end of the first lead screw assembly 104 is connected to the drive shaft assembly 105. The first handwheel 106 drives the drive assembly to move the first lead screw assembly 104. The output end of the first lead screw assembly 104 is connected to the lifting rod 101. The lifting rod 101 passes through the first lead screw assembly 104, realizing lifting and lowering relative to the first lead screw assembly 104. The lifting rod 101 passes through the lifting hole 1107 of the loading mounting bracket 111.

[0082] The drive shaft assembly 105 may include a drive shaft, a bearing housing, and a universal joint coupling. The first handwheel 106 is connected to the universal joint coupling via the drive shaft, thereby connecting to the first threaded nut assembly 104. The bearing housing mounts the drive shaft onto the first top plate 1101. The drive shaft assembly 105 extends the first handwheel 106 beyond the first top plate 1101, facilitating its rotation and balancing the weight of the lifting rod 101. The universal joint coupling eliminates the effects of machining errors causing non-coaxiality of components; multiple universal joint couplings can be connected in series.

[0083] The following is based on the above Figures 1 to 10 The glass assembly cold bending apparatus shown in this application embodiment provides a glass assembly cold bending method, including the following steps S1 to S12.

[0084] S1: Determine the number and location of loading points along the edge of the glass assembly based on the cold bending requirements, size, and shape of the glass assembly, thereby determining the number and placement of the cold bending assembly 100.

[0085] S2: Place multiple cold-bending components 100 on a horizontal steel mounting platform 200.

[0086] S3: The assembled, bent and twisted installation frame is placed on the arc-shaped rubber block 125 of the support member 121 of the support mechanism 120. According to the tilt angle of the installation frame in the actual project or the test requirements, the first lifting module 126 drives the pallet 124 to move along the guide rail 129 to adjust the height so that the arc-shaped rubber block 125 contacts the installation frame to achieve the support function.

[0087] S4: The center of the pressure head 113 of the cold bending assembly 100 is aligned with the loading point position through the second adjustment elongated hole 144 of the adapter 140.

[0088] S5: Secure the second base plate 143 of the adapter 140 to the mounting platform 200 using bolts or a screw clamp.

[0089] S6: Install positioning component 122 and connect it to the support plate 124 with bolts to prevent the mounting frame from rotating out of the plane and to achieve a fixing effect.

[0090] S7: Attach or place double-sided tape or adhesive strips on the upper surface of the mounting frame.

[0091] S8: Adjust the loading mechanism 110 to the second working position, hoist the horizontal glass plate above the installation frame, place multiple jacks and other support devices under the glass plate, and adjust the glass plate to a horizontal state using a leveling instrument, and install test instruments such as displacement gauges and strain gauges.

[0092] S9: After removing the jacks and other supporting devices, the glass panel deforms under its own weight along with the installation frame.

[0093] S10: Switch the loading mechanism 110 from the second working position to the first working position, and control the first lifting module 126 to lower the pressure head 113 until it contacts the glass plate and generates a downward displacement to achieve cold bending loading, so that the glass plate and the mounting frame fit tightly together. The loading mechanism 110 can be applied only to areas where the glass plate and the mounting frame have poor contact.

[0094] S11: Cold bending loading is completed after the glass plate is bonded to the mounting frame with double-sided adhesive or strips.

[0095] S12: Switch the loading device from the first working position to the second working position to avoid collision, and then lift out or replace the glass component.

Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
