[0036] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0038] Curved glass curtain walls have rich architectural expression and good environmental integration. In actual projects, hot bending or cold bending is usually used to achieve glass curved surface forming. In the hot bending method, static mold bending and roller bending are the two most commonly used processes. Among them, static mold bending requires heating the glass to a flow state, and then the glass bends under its own weight to fit the mold to achieve a curved surface shape. Therefore, this method requires the production of corresponding molds for glass with different curved surfaces, which has high costs and energy consumption. Roller bending adjusts the tilted roller to form a curved surface for the glass without the need to configure a mold, but the optical quality of the glass is affected by the roller wave distortion between the verticality of the roller and its relative position. The cold bending method forms a curved surface by applying forced displacement to the glass at room temperature. It has low cost and high flexibility. Among them, the forced displacement of the corner cold bending is at the corner of the glass, which can easily realize the curved surface of the glass, especially the reverse hyperbolic forming.

[0039] After cold bending, stress will be generated inside the glass, and it will exist for a long time during the service of the glass curtain wall. How to evaluate the safety of cold-bent glass curtain walls is crucial. Existing glass testing methods include three-point bending test, four-point bending test and elastic modulus test, etc. The corresponding testing equipment includes three-point bending test machine, four-point bending test machine, universal material testing machine, etc. However, the existing bending test equipment does not consider the influence of deadweight on the forming of glass curved surface in the corner bending test of glass plate, and the test results are not comprehensive, which makes the performance test analysis of glass inaccurate.

[0040] In order to solve the problems in the prior art, the embodiment of the present application provides a glass plate cold bending test device. The glass plate cold bending test device provided by the embodiment of the present application is first introduced below.

[0041] Figure 1 A schematic diagram of a structure of a glass plate cold bending test device provided in an embodiment of the present application is shown. Figure 2 A structural schematic diagram of a glass plate cold bending test device provided in an embodiment of the present application is shown.

[0042] like Figure 1 and Figure 2As shown, the embodiment of the present application provides a glass plate cold bending test device, including: a mounting platform 300, a test mechanism 200 and a clamping mechanism 100, the mounting platform 300 includes a plurality of test positions, the plurality of test positions include a loading position 302 and at least two diagonally arranged clamping positions 301; the test mechanism 200 is arranged at the loading position 302, the test mechanism 200 includes a supporting assembly 210 and a loading assembly 220 installed on a side of the supporting assembly 210 facing away from the mounting platform 300, the supporting assembly 210 includes a plurality of test positions along the test mechanism 201, and a plurality of test positions include a plurality of test positions including a loading position 302 and at least two diagonally arranged clamping positions 301; the test mechanism 200 is arranged at the loading position 302, the test mechanism 200 includes a supporting assembly 210 and a loading assembly 220 installed on a side of the supporting assembly 210 facing away from the mounting platform 300, and the supporting assembly 210 includes a plurality of test positions along the test mechanism 201. 0, the supporting member 211 is used to support the plate corner of the glass plate 310 to be tested and detect the plate corner pressure of the glass plate 310 to be tested during the descending process of the supporting member 211, and the loading assembly 220 is arranged opposite to the supporting member 211, and is used to apply pressure to the plate corner of the glass plate 310 to be tested when the supporting member 211 is in a pressure-free state; the clamping mechanism 100 is arranged at the clamping position 301, and is used to clamp the plate corner of the glass plate 310 to be tested and detect the pressure of the plate corner of the corresponding clamped glass plate 310 to be tested.

[0043] The mounting platform 300 includes a plurality of test positions, including a loading position 302 and at least two diagonally arranged clamping positions 301; the test mechanism 200 is arranged at the loading position 302, and is used to support the plate corner of the glass plate 310 to be tested so that it falls slowly when the glass falls by its own weight, and to apply a loading force to the plate corner at a specified time; the clamping mechanism 100 is arranged at the clamping position 301, and is used to clamp the plate corner of the glass plate 310 to be tested, and detect the pressure of the plate corner of the glass plate 310 to be tested. The plurality of test positions are arranged based on the plurality of plate corner positions of the glass plate 310 to be tested. For example, the glass plate 310 to be tested is a rectangular plate structure, and the clamping mechanism 100 is arranged at least at the plate corner positions arranged diagonally to clamp the glass, so that the entire glass plate 310 to be tested is kept at a specific height and horizontal position.

[0044] For example, for a rectangular glass plate 310 to be tested, including two groups of diagonal plate corners, a clamping mechanism 100 may be set at one group of diagonal plate corners, that is, the mounting platform 300 includes two clamping positions 301, and a testing mechanism 200 may be set at the other group of diagonal plate corners, that is, the mounting platform 300 includes two loading positions 302. Alternatively, a clamping mechanism 100 may be set at three plate corners, that is, the mounting platform 300 includes three clamping positions 301, and a testing mechanism 200 may be set at the remaining plate corner, that is, the mounting platform 300 includes one loading position 302. When the mounting platform 300 has multiple loading positions 302, the testing mechanism 200 placed at the loading position 302 operates synchronously. This allows testing of glass plates 310 to be tested in different shapes, and the glass plates 310 to be tested may be tested by cold bending into different curved surface shapes, such as a positive Gaussian surface or a negative Gaussian surface.

[0045] In addition, the constraints of the multiple corner plates of the glass plate 310 to be tested by the multiple clamping mechanisms 100 can be the same or different. For example, the multiple corner plates of the glass plate 310 to be tested by the multiple clamping mechanisms 100 are all subjected to rolling axis constraints, clamping constraints or pin constraints; of course, some clamping mechanisms 100 can also be subjected to roller constraints on some corner plates of the glass plate 310 to be tested, and other clamping mechanisms 100 can be subjected to connector constraints on other corner plates of the glass plate 310 to be tested. Cold bending performance tests of the glass plate 310 to be tested under different constraint conditions can be performed.

[0046] The testing mechanism 200 includes a supporting assembly 210 and a loading assembly 220. The supporting assembly 210 is connected to the mounting platform 300. The loading assembly 220 is placed above the supporting assembly 210. The supporting assembly 210 is used to support the corners of the glass plate 310 to be tested. The loading assembly 220 is used to apply downward pressure to the corners of the glass plate 310 to be tested.

[0047] The supporting assembly 210 includes a supporting member 211 that can be raised and lowered along the height direction of the testing mechanism 200. The supporting member 211 is used to support the plate corners of the glass plate 310 to be tested and detect the plate corner pressure of the glass plate 310 to be tested during the descending process of the supporting member 211. In the initial state, the glass plate 310 to be tested is placed on the testing mechanism 200 and the clamping mechanism 100, the glass plate 310 to be tested and the mounting platform 300 tend to be horizontal, the self-weight of the glass plate 310 to be tested has no bending effect on each plate corner, and the pressure inspection values ​​of each plate corner by the testing mechanism 200 and the clamping mechanism 100 tend to be equal. The supporting plates 2110 of each supporting assembly 210 are controlled to move slowly and evenly toward the mounting platform 300, so that the corresponding plate corners of the glass plate 310 to be tested continuously bend and fall toward the mounting platform 300 under the action of gravity, and the supporting member 211 detects the pressure of the corresponding plate corners in real time until the pressure value detected by the supporting member 211 is zero, that is, the supporting member 211 is in a pressure-free state.

[0048] The loading assembly 220 is arranged opposite to the supporting member 211, and is used to apply pressure to the plate corner of the glass plate 310 to be tested when the supporting member 211 is in a pressure-free state. The loading assembly 220 moves down to contact the plate corner of the glass plate 310 to be tested in a state of self-weight bending, and then presses down in the direction of the mounting platform 300 at a uniform speed to apply a loading force to the plate corner. Based on the test requirements, the loading assembly 220 can be pressed down to a specified displacement, or pressed down to a specified pressure, or pressed down until the plate corner of the glass plate 310 to be tested is damaged. The glass plate cold bending test device of the embodiment of the present application can obtain parameters such as shape change and force change in the process of bending the plate corner of the glass plate 310 due to self-weight in real time, so that the test results are more comprehensive and more accurate. The test process and the obtained parameters are used to analyze the performance of the subsequent glass plate 310, as well as the comprehensive consideration of the subsequent cold bending process of the glass plate 310, which are very important.

[0049] Continue to refer Figure 1 In one embodiment of the present application, in order to achieve flexible installation of the mounting platform 300 and the test mechanism 200 and the clamping mechanism 100, the mounting platform 300 includes a first mounting hole 303 arranged at intervals along rows and columns, the test mechanism 200 and the second mounting hole 304 are arranged, and the clamping mechanism 100 is arranged with a third mounting hole 305. The test mechanism 200, the clamping mechanism 100 and the mounting platform 300 are detachably connected through the first mounting hole 303, the second mounting hole 304 and the third mounting hole 305.

[0050] Taking the test mechanism 200 as an example, the first mounting holes 303 arranged at intervals in rows and columns provide the test mechanism 200 with mounting points adapted to glass plates 310 of different sizes and shapes, thereby improving the flexible installation of the test mechanism 200. A second mounting hole 304 is provided on the side of the test mechanism 200 that contacts the mounting platform 300. The second mounting hole 304 corresponds to the hole diameter and hole spacing of the first mounting hole 303. The test mechanism 200 and the mounting platform 300 are detachably connected by fasteners such as bolts. During the installation process, the fasteners are passed through the first mounting hole 303 and the second mounting hole 304 and tightened to fix the test mechanism 200. When the test mechanism 200 needs to be disassembled or adjusted, it can be easily completed by simply loosening the fasteners.

[0051] The detachable connection enables the test mechanism 200 to be easily installed and disassembled, which is convenient for maintenance and replacement. When the glass plate cold bending test device needs to adapt to glass plates 310 of different shapes and sizes, the test mechanism 200 can be easily adjusted or replaced. If a component on the test mechanism 200 or the mounting platform 300 fails or is damaged, the component can be removed and replaced separately without replacing the entire device, thereby reducing maintenance costs and time and facilitating maintenance. The modular design achieved by the detachable connection makes the glass plate cold bending test device easier to assemble and transport. The individual components can be manufactured and stored independently, and then assembled into a complete device when needed.

[0052] Figure 3 A schematic diagram of the three-dimensional structure of an adapter 320 provided in some embodiments of the present application is shown;

[0053] Figure 4 for Figure 3 A front view of the adapter 320 is shown.

[0054] like Figure 1 , Figure 3 and Figure 4 As shown, the testing mechanism 200 also includes an adapter seat 320, which is connected between the supporting assembly 210 and the mounting platform 300. The adapter seat 320 is relatively provided with an adjustable top support member 321 along the length direction of the supporting assembly 210, and the adjustable top support member 321 abuts against the supporting assembly 210.

[0055] In order to achieve fine-tuning between the test mechanism 200 and the installation platform 300, the test mechanism 200 also includes an adapter seat 320, which includes a first seat plate 141 and a second seat plate 143 that are relatively arranged along the height direction of the test mechanism 200; the first seat plate 141 is provided with a plurality of first adjustment long holes 142 along the length direction of the adapter seat 320, and the adapter seat 320 is detachably connected to the supporting assembly 210 through the first adjustment long holes 142; the second seat plate 143 is provided with a plurality of second adjustment long holes 144 along the width direction of the adapter seat 320, and the adapter seat 320 is detachably connected to the installation platform 300 through the second adjustment long holes 144.

[0056] The adapter seat 320 includes a first seat plate 141 and a second seat plate 143, between which a connecting plate 145 and a reinforcing plate are connected. The first seat plate 141 and the second seat plate 143 are relatively arranged on the upper and lower sides of the connecting plate 145 along the height direction of the testing mechanism 200. The fourth reinforcing plate 147 is connected between the first seat plate 141 and the connecting plate 145, and the fifth reinforcing plate 146 is connected between the second seat plate 143 and the connecting plate 145, thereby increasing the strength of the adapter seat 320.

[0057] A plurality of first adjustment long holes 142 are provided on the first seat plate 141 along its length direction. The first adjustment long holes 142 detachably connect the adapter seat 320 and the supporting assembly 210 through bolts, pins or other fasteners. Since they are first adjustment long holes 142, the relative position between the adapter seat 320 and the supporting assembly 210 can be adjusted within a certain range to adapt to different installation requirements or adjustment accuracy. Among them, the lengths of the plurality of first adjustment long holes 142 can be different, and the first adjustment long holes 142 are not provided in the area where the supporting assembly 210 contacts the first seat plate 141, so as to ensure the strength of the first seat plate 141, and the plurality of first adjustment long holes 142 can be arranged parallel to each other.

[0058] A plurality of second adjustment long holes 144 are provided on the second seat plate 143 along its width direction. The second adjustment long holes 144 enable the adapter seat 320 to be detachably connected to the mounting platform 300, and also support position adjustment within a certain range. This is essential to ensure the stability and accuracy of the adapter seat 320 on the mounting platform 300. Among them, the lengths of the plurality of second adjustment long holes 144 may be different, and the first adjustment long hole 142 is not provided in the area where the connecting plate 145 contacts the second seat plate 143, so as to ensure the strength of the second seat plate 143, and the plurality of second adjustment long holes 144 may be arranged parallel to each other.

[0059] By providing a first adjustment slot 142 and a second adjustment slot 144 that are perpendicular to the adjustment direction, the adapter 320 can be fine-tuned in length and width, thereby achieving connection between the test mechanism 200 and the installation platform 300. The adapter 320 can not only serve as a bridge between the test mechanism 200 and the installation platform 300, but can also be flexibly adjusted according to specific installation environments or requirements. This design greatly increases the scope of application and installation convenience of the test mechanism 200. The detachable connection between the adapter 320 and the test mechanism 200 and the installation platform 300 makes it easier to operate when maintenance or replacement of components is required. This reduces maintenance costs and improves work efficiency.

[0060] The adapter 320 is provided with an adjustable top support member 321 along the length direction of the supporting assembly 210, and the adjustable top support member 321 abuts against the supporting assembly 210. Both adjustable top support members 321 are installed on the side of the first seat plate 141 facing away from the second seat plate 143, and the adjustable top support member 321 includes an adjustable base 3211 and an adjusting screw 3212. The adjustable base 3211 is provided with an internal threaded hole and is threadedly connected with the adjustable screw 3212 to achieve telescopic adjustment along the length direction of the supporting assembly 210. The adjusting screws 3212 of the two adjustable top support members 321 are coaxial to ensure symmetry of the force acting on the supporting assembly 210.

[0061] The clamping mechanism 100 may also include a first adapter seat 320 for connecting to the mounting platform 300 . The structure of the first adapter seat 320 is the same as that of the adapter seat 320 of the testing mechanism 200 , and will not be described in detail herein.

[0062] The clamping mechanism 100 of the embodiment of the present application is introduced below. Figure 5 A schematic diagram of a three-dimensional structure of a clamping mechanism 100 provided in some embodiments of the present application is shown; Figure 6 A partial structural schematic diagram of a clamping assembly 110 provided in some embodiments of the present application is shown.

[0063] like Figure 5 and Figure 6 As shown, in a specific embodiment of the present application, the clamping mechanism 100 includes a clamping support frame 120 and a clamping assembly 110, the clamping support frame 120 is installed on the mounting platform 300, the clamping assembly 110 is connected to the clamping support frame 120, the clamping assembly 110 includes a first force detection member 112 and an insertion cavity 111 formed on the side of the first force detection member 112 away from the clamping support frame 120, the opening direction of the insertion cavity 111 is parallel to the mounting platform 300, and is used to accommodate the plate corner of the glass plate 310 to be tested.

[0064] The clamping assembly 110 is connected to the clamping support frame 120, and the clamping support frame 120 is used to support the clamping assembly 110, so that the clamping assembly 110 can more stably support the glass plate 310 to be tested. The clamping assembly 110 can be installed on the top of the clamping support frame 120, or the clamping assembly 110 can be placed on one side of the clamping support frame 120 extending in the circumferential direction.

[0065] The clamping assembly 110 includes a first force detection member 112 and an insertion cavity 111, and the insertion cavity 111 is used to accommodate the plate corner of the glass plate 310 to be tested. The plate corner of the glass plate 310 to be tested is inserted into the insertion cavity 111 from the opening of the insertion cavity 111, so as to limit the glass plate 310 to be tested in multiple directions. The openings of the two insertion cavities 111 of the diagonally arranged clamping mechanism 100 are arranged oppositely, and the shape of the insertion cavity 111 is adapted to the plate corner of the glass plate 310 to be tested. The insertion cavity 111 can be formed by cutting out a plate with a certain thickness or by overlapping a plurality of plates. Since the glass plate 310 to be tested is parallel to the area of ​​the installation platform 300, the opening direction of the insertion cavity 111 is parallel to the installation platform 300, so that the glass plate 310 to be tested can be inserted into the insertion cavity 111 without external force.

[0066] A detection connection plate 115 may be provided below the first force detection member 112, the first force detection member 112 is fixedly connected to the detection connection plate 115, and the detection connection plate 115 is connected to the clamping support frame 120. The first force detection member 112 detects the load of the plate corner placed in the plug-in cavity 111. The first force detection member 112 may be a pressure sensor, a tension and compression sensor, etc. A long hole may be provided along the width direction on the detection connection plate 115, and the first force detection member 112 may be adjustably connected to the long hole along the length direction of the detection connection plate 115, so as to achieve fine adjustment of the position between the clamping assembly 110 and the glass plate 310 to be tested.

[0067] Figure 7 A schematic diagram of an exploded view of a clamping assembly 110 provided in some embodiments of the present application is shown.

[0068] like Figure 7 As shown, in a specific embodiment of the present application, the clamping assembly 110 also includes a ball plate group 114 and a clamping plate group 113, the ball plate group 114 includes a first flexible plate 101 having a first groove, a second flexible plate 103 having a second groove, and a ball piece 102 placed in the first groove and the second groove, the first flexible plate 101 is connected to the first force detection piece 112, and the second flexible plate 103 is connected to the clamping plate group 113; the clamping plate group 113 and the second flexible plate 103 are spaced apart and connected along the height direction of the clamping mechanism 100 to form a plug-in cavity 111.

[0069] The first flexible plate 101 has a first groove for accommodating and positioning the ball 102. The first flexible plate 101 allows a certain degree of deformation when subjected to external force to adapt to small displacements or angle changes during the clamping process. The second flexible plate 103 has a second groove, which is opposite to the groove of the first flexible plate 101 and together forms a space for accommodating the ball 102. The second flexible plate 103 also has a certain degree of flexibility to ensure the flexibility and stability of clamping. Among them, the first groove is opened at the center of mass of the first flexible plate 101, and the second groove is opened at the center of mass of the second flexible plate 103. The ball 102 is placed in the first groove and the second groove, serving as a hinge connecting the first flexible plate 101 and the second flexible plate 103. The ball 102 enables the clamping assembly 110 to be fine-tuned in multiple directions to adapt to workpieces of different shapes and sizes, and to achieve roller constraints on the plate corners of the glass plate 310 to be tested.

[0070] The first flexible plate 101 and the first force detection member 112 can be connected by bolts, pins or other fastening structures to ensure that the first force detection member 112 can accurately sense and measure the force generated during the clamping process. The second flexible plate 103 and the clamping plate group 113 can be connected by bolts, pins or other fastening structures, and stability and flexibility are also required to be ensured so that the clamping plate group 113 can be adaptively adjusted according to the shape and size of the workpiece. In order to ensure the accuracy of the first force detection member 112, the center line of the first force detection member 112 is collinear with the center of the ball member 102.

[0071] The clamping plate group 113 and the second flexible plate 103 are spaced apart and connected along the height direction of the clamping mechanism 100 to form a plug-in cavity 111, wherein the clamping plates of the clamping plate group 113 are arranged in parallel with the second flexible plate 103, and the clamping plate group 113 and the second flexible plate 103 can be connected by bolts, or bonded by other connecting blocks, etc. For example, the second flexible plate 103 and the clamping plate group 113 are spaced apart and connected by bolts at the four corners of the plate body. Among them, the long side of the clamping plate of the clamping plate group 113 is the opening of the plug-in cavity 111. For example, the clamping plate group 113 includes a clamping plate and a flexible pad connected to one side of the clamping plate close to the second flexible plate 103, and the material of the flexible pad can be rubber or polyurethane PU elastomer to prevent the clamping plate group 113 from directly contacting the glass plate 310 to be tested and scratching the glass plate 310 to be tested.

[0072] Further, in an optional embodiment of the present application, the clamping plate group 113 is detachably connected to the second flexible plate 103. This facilitates the hoisting and transportation of the glass plate 310 to be tested. When the glass plate 310 to be tested is placed on the clamping mechanism 100, the clamping plate group 113 is removed to make the glass plate 310 to be tested contact with the second flexible plate 103. After the glass plate 310 to be tested is placed, the clamping plate group 113 is connected to the second flexible plate 103 to achieve clamping and restraining of the glass plate 310 to be tested. When the glass plate 310 to be tested is transported, the clamping plate group 113 is removed in the same manner.

[0073] In addition, after the clamping plate group 113 of the clamping mechanism 100 is separated from the second flexible plate 103, the clamping mechanism 100 can be used as a supporting component 210, thereby increasing the application scope of the clamping mechanism 100, reducing the preparation and design costs, and achieving dual uses of one machine.

[0074] Figure 8 A schematic structural diagram of the first lifting module 130 provided in some embodiments of the present application is shown.

[0075] like Figure 5 and Figure 8As shown, in other optional embodiments of the present application, the clamping mechanism 100 also includes a first lifting module 130 , which passes through the clamping support frame 120 and is connected to the clamping assembly 110 , and is used to enable the clamping assembly 110 to perform lifting and lowering movements along the clamping support frame 120 .

[0076] The first lifting module 130 is connected to the clamping assembly 110, and drives the clamping assembly 110 to perform linear motion along the height direction of the clamping mechanism 100, thereby adjusting the distance of the clamping assembly 110 relative to the mounting platform 300, so that the clamping assembly 110 is in contact with the glass plate 310. The first lifting module 130 is used to realize the adjustability of the clamping assembly 110 along the height direction, and to meet the bending displacement requirements of different glass plates 310.

[0077] Specifically, Figure 8 As shown, the first lifting module 130 includes a hand wheel 131, a belt transmission assembly 132, a driving gear set 133, a first screw 134 and a second nut assembly 135. The hand wheel 131 is connected to the belt transmission assembly 132 by shaft transmission. The belt rotation assembly is connected to the input end of the driving gear set 133 by transmission. The output end of the driving gear set 133 is connected to the first screw 134. The first screw 134 is connected to the second nut assembly 135 by through-fitting. The second nut assembly 135 is fixedly connected to the clamping assembly 110. The hand wheel 131 rotates through the belt transmission assembly 132 and the driving gear set 133 to drive the first screw 134 to rotate. The first screw 134 rotates to drive the second nut assembly 135 to move up and down along the first screw 134, thereby driving the clamping assembly 110 to move up and down along the first screw 134. The first screw 134 is arranged along the height direction of the clamping mechanism 100. The input end and the output end of the driving gear set 133 may also be arranged up and down along the axis, or may be arranged at an angle, for example, the input end and the output end of the driving gear set 133 may be arranged at 90 degrees, so as to facilitate the rotation of the hand wheel 131. The belt transmission assembly 132 may extend the distance between the hand wheel 131 and the driving gear set 133, thereby raising the hand wheel 131 for easy operation, and the hand wheel 131 and the clamping assembly 110 are placed on opposite sides of the first screw 134 in the radial direction.

[0078] Of course, in other embodiments of the present application, the motor 2220 may be used to drive the driving gear set 133 to rotate, so as to achieve the lifting movement of the clamping assembly 110. In addition, the first lifting module 130 may also be a hydraulic cylinder or a cylinder structure.

[0079] Continue to refer Figure 5 and Figure 8In an optional embodiment of the present application, the support mounting frame is provided with a guide rail 1217 along the height direction, and the first lifting module 130 is slidably connected to the guide rail 1217, and penetrates the support mounting frame along the depth direction and is connected to the clamping assembly 110. The first lifting module 130 and the clamping assembly 110 are placed on both sides of the support mounting frame, which can better balance the weight of the glass plate 310 on the clamping assembly 110, maintain the balance of the clamping mechanism 100, and improve the stability of the clamping mechanism 100.

[0080] The support mounting frame is provided with a guide rail 1217 along the height direction. The guide rail 1217 is arranged parallel to the first lead screw 134. The first lifting module 130 is slidably connected to the guide rail 1217, that is, the second nut assembly 135 is slidably connected to the guide rail 1217. The second nut assembly 135 includes a nut sleeve, an extension plate and a slider plate. The nut sleeve is sleeved and matched with the first lead screw 134. One end of the extension plate is fixedly connected to the nut sleeve, and the other end is fixedly connected to the slider plate. The side of the slider plate close to the nut sleeve is slidably matched with the guide rail 1217, and the side facing away from the nut sleeve is fixedly connected to the clamping assembly 110. The driving gear set 133 is fixedly connected to the support mounting frame. The support mounting frame plays a role in firmly connecting the first lifting module 130. The guide rail 1217 plays a guiding role in the lifting movement of the first lifting module 130, so that the first lifting module 130 can stably lift and lower the clamping assembly 110.

[0081] Fig. 9 A schematic structural diagram of a clamping support frame 120 provided in some embodiments of the present application is shown.

[0082] like Fig. 9 As shown, in a specific embodiment of the present application, the support mounting frame 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 is provided with a through area 1213 along the thickness direction. The guide rail 1217 is installed on the opposite sides of the through area 1213 along the height direction of the connecting column 1211. The second lifting module 222 penetrates the through area 1213 and is connected to the support plate 2110. A third reinforcing plate 1214 is arranged 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 130 penetrates the through area 1213 and slides with the guide rail 1217, and is connected to the clamping assembly 110.

[0083] The guide rail 1217 is installed on the side of the connecting column 1211 facing away from the handwheel 131. The driving gear group 133 is fixedly connected to the second base plate 1212. A second mounting hole 304 is opened on the second base plate 1212, which can be used to connect with the mounting platform 300 or the adapter 320. The end of the second lead screw facing away from the driving gear group 133 is connected to the second top plate 1210.

[0084] The following is an introduction to the test mechanism 200 of the embodiment of the present application. Fig.10 A schematic structural diagram of a testing mechanism 200 provided in some embodiments of the present application is shown.

[0085] like Fig.10 As shown, in other optional embodiments of the present application, the loading component 220 includes a loading mounting frame 221, a second lifting module 222, and a glue pressing head 223 installed at the end of the second lifting module 222. The second lifting module 222 is arranged along the length direction of the loading component 220, and one end is installed on the side of the loading mounting frame 221 facing away from the supporting component 210, and the glue pressing head 223 at the other end extends toward the supporting member 211.

[0086] The loading mounting frame 221 is connected to the side of the supporting assembly 210 facing away from the mounting platform 300, and the loading mechanism is placed above the supporting assembly 210, which is conducive to the second lifting module 222 applying downward pressure to the plate corner of the glass plate 310. The second lifting module 222 has two opposite ends along the length direction, one end is connected to the glue pressing head 223, and the other end is connected to the loading mounting frame 221. The glue pressing head 223 is used to directly contact the glass plate 310. The glue pressing head 223 can be made of rubber or plastic material or polyoxymethylene to avoid damage to the glass plate 310 during the loading process. When the supporting member 211 is in a pressure-free state, the second lifting module 222 drives the glue pressing head 223 to descend, and further applies a loading force to the plate corner that has been bent under its own weight along the height direction of the cold bending assembly to test the plate corner bending performance of the glass plate 310.

[0087] When the glue pressing head 223 is continuously pressed down, the supporting plate 2110 avoids the pressure. For example, after the supporting plate 2110 is in a pressure-free state, the supporting member 211 can quickly drop to the bottom of the testing mechanism 200 to avoid the loading of the glue pressing head 223 .

[0088] Fig.11 A schematic diagram of the structure of a loading and mounting frame 221 provided in some embodiments of the present application is shown; Fig.12 for Fig.11 A front view of the loading mount 221 is shown.

[0089] like Fig.11 and 12As shown, in some other embodiments of the present application, the loading mounting frame 221 includes a supporting arm frame and a cantilever frame, the supporting arm frame is connected to the supporting mounting frame, and the cantilever frame is connected to the side of the supporting arm frame facing away from the supporting mounting frame, and is extended in the depth direction. One end of the cantilever frame is connected to the supporting arm frame, and the other end is extended in the direction facing away from the supporting arm frame, so that the glue pressing head 223 of the second lifting module 222 installed on the cantilever frame is arranged opposite to the plate corner of the glass plate 310. The setting of the cantilever frame is conducive to the second lifting module 222 to extend out to cooperate with the supporting member 211 to pressurize the glass plate 310.

[0090] Among them, the loading mounting frame 221 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 extension direction of the other end is opposite. The first reinforcing plate 1104 is connected between the first connecting plate 1102 and the first bottom plate 1103 to form a support arm frame, the first lifting module 130 is installed on the first top plate 1101, the first top plate 1101 is provided with a lifting hole 1107 for the first lifting module 130 to penetrate and connect, the second reinforcing plate 1105 is connected between the first connecting plate 1102 and the first top plate 1101 to form a rotating arm frame, the sealing plate 1109 is connected to the first top plate 1101 and the second reinforcing plate 1105, and is arranged opposite to the first connecting plate 1102. Among them, a plurality of first reinforcing plates 1104 are arranged at intervals along the length direction of the first bottom plate 1103, and a plurality of second reinforcing plates 1105 are arranged at intervals along the length direction of the first top plate 1101. The provision of the first reinforcing plate 1104 and the second reinforcing plate 1105 increases the bending stiffness of the first top plate 1101 and the lateral bending stiffness of the first connecting plate 1102 , and the provision of the sealing plate 1109 improves the bending stiffness of the first top plate 1101 .

[0091] Fig.13 A schematic structural diagram of a second lifting module 222 provided in some embodiments of the present application is shown.

[0092] like Fig.13 As shown, in another optional embodiment of the present application, the loading assembly 220 also includes a floating joint 226 and a second pressure detection component 227, and the second pressure detection component 227, the floating joint 226 and the glue pressing head 223 are coaxially connected in sequence to the end of the second lifting module 222.

[0093] Specifically, the second lifting module 222 includes a driving member and a lifting rod. The second pressure detection member 227 and the floating joint 226 are arranged along the axial direction of the lifting rod. The lifting rod is connected to the loading mounting frame 221 through the driving member. The second pressure detection member 227 and the floating joint 226 are sequentially arranged between the lifting rod and the glue pressing head 223. The floating joint 226 can rotate with the surface of the glass plate to achieve physical alignment and meet the large deformation requirements of the cold bending test glass.

[0094] The driving member serves as a power source to drive the lifting rod to perform lifting motion. The driving member can be a combination of a motor 2220, a hydraulic cylinder or a pneumatic cylinder, etc. and a first screw nut assembly 2221, depending on the overall design and requirements of the device. The motor 2220 drive usually has higher precision and controllability, while the hydraulic or pneumatic cylinder may provide greater output force. The first screw nut assembly 2221 includes a vertically arranged input end and an output end, the input end is connected to the motor 2220, and the output end is connected to the lifting rod, and the lifting rod can be a second screw.

[0095] The lifting rod transmits the linear motion of the driving member to the glue head 223, thereby applying cold bending pressure to the glass plate 310. The lifting rod should have sufficient rigidity and stability to ensure that no bending or deviation occurs when pressure is applied. The second pressure detection member 227 is installed between the lifting rod and the glue head 223, and is used to monitor and feedback the pressure value applied to the glass plate 310 in real time. This is crucial for controlling the pressure during the cold bending process, ensuring processing accuracy and achieving test results. The second pressure detection member 227 should have high sensitivity and high accuracy to accurately measure and record pressure data. The floating joint 226 is arranged between the lifting rod and the glue head 223, and is located below the second pressure detection member 227. The floating joint 226 allows the glue head 223 to have a certain adaptive adjustment ability when applying pressure to adapt to the curvature change of the surface of the glass plate 310. This adaptive adjustment helps to ensure the uniformity of pressure distribution and improve the effect of applying cold bending pressure. Among them, multiple floating joints 226 can be arranged in parallel, thereby meeting the surface changes of the curved glass plate 310 with large curvature.

[0096] Continue to refer Fig.10 In some embodiments of the present application, the support assembly 210 further includes a support mounting frame 212, the support member 211 is mounted on the support mounting frame 212, and the loading mounting frame 221 is detachably mounted on the side of the support mounting frame 212 facing away from the mounting platform 300. For example, the support assembly 210 may use the clamping mechanism 100, in other words, the support mounting frame 212 and the clamping support frame 120 may have the same structure. The clamping mechanism 100 may be used alone, and may be used in combination with the loading mechanism.

[0097] For example, the loading mounting frame 221 is connected to the supporting mounting frame 212 through the rotating shaft mechanism 224 and the locking mechanism 225 to realize the switching of the loading mechanism between the first working position and the second working position; in the state of the first working position, the locking mechanism 225 is locked to the loading mounting frame 221 and the supporting mounting frame 212, and the glue pressing head 223 and the supporting member 211 are arranged relative to each other in the height direction; in the state of the second working position, the locking mechanism 225 is unlocked to the loading mounting frame 221 and the supporting mounting frame 212, and the loading mounting frame 221 and the supporting mounting frame 212 are arranged to rotate and stagger around the rotating shaft mechanism 224. The adapter 320 is connected between the supporting mounting frame 212 and the mounting platform 300, and the adjustable top support member 321 is in contact with the supporting mounting frame 212.

[0098] The support arm is displaceably connected to the support mounting frame 212. In the first working position, for example, the rotating shaft mechanism 224 includes a rotating shaft and a sleeve. The sleeve is sleeved in the rotating shaft to achieve the rotation avoidance of the sleeve around the rotating shaft. The rotating shaft is installed on the side of the second top plate 1210 of the support mounting frame 212 facing away from the connecting column 1211, the rotating shaft is installed at the mass center of the second top plate 1210, the sleeve is installed on the side of the first bottom plate 1103 of the loading mounting frame 221 facing away from the supporting assembly 210, and the sleeve is installed at the mass center of the first bottom plate 1103. The locking mechanism 225 includes a bolt fastening structure. The second top plate 1210 is provided with a second fastening hole 1216 for connecting with the locking mechanism 225; the first bottom plate 1103 is provided with a first fastening hole 1108 for connecting with the locking mechanism 225; the lifting hole 1107 and the sleeve are placed on both sides of the first connecting plate 1102 in the thickness direction. The bolt fastening structure penetrates the first fastening hole 1108 and the second fastening hole 1216 to lock the loading mechanism and the supporting assembly 210, and the bolt fastening structure is loosened to achieve unlocking. Of course, the locking mechanism 225 can also be a pin shaft, a clamping structure, etc.

[0099] Further, continue to refer to Fig.10 In an embodiment of the present application, the supporting assembly 210 also includes a third lifting module 213 arranged along the height direction of the supporting mounting frame 212, the supporting member 211 includes a support plate 2110 and a third force detection member 2111, the third lifting module 213 passes through the supporting mounting frame 212 and is connected to the support plate 2110, and is used to make the support plate 2110 perform lifting and lowering movements along the supporting mounting frame 212, and the third force detection member 2111 is installed on the side of the support plate 2110 facing away from the mounting platform 300.

[0100] Among them, the structure of the third lifting module 213 is the same as that of the first lifting module 130, which will not be repeated here. The upper surface of the support plate 2110 is connected to the third force detection member 2111 for detecting the pressure change of the plate corner of the glass plate 310 to be tested under the influence of gravity during the continuous bending process. When the pressure value of the third force detection member 2111 is equal to zero, the loading assembly 220 continues to press down on the plate corner of the bent glass plate 310 to be tested. For example, a pad can be set on the upper surface of the third force detection member 2111 to better support the glass plate 310 to be tested. In addition, the structure of the supporting member 211 can also be the same as that of the clamping assembly 110, and the upper surface of the clamping plate group 113 in the clamping assembly 110 is in contact with the plate corner of the glass plate 310 to be tested.

[0101] Based on the embodiments of this application Figures 1 to 13 A glass plate cold bending test device is provided, and a glass plate 310 test method is provided, including the following steps S1 to S8.

[0102] S1: Place the mounting platform 300 on the ground and use the spiral legs to adjust the mounting platform 300 to a horizontal level, and determine the loading position 302 and the clamping position 301 based on the size of the glass plate 310, the number of plate corners, the test requirements and the preset glass curved surface shape.

[0103] S2: Place the test mechanism 200 and the clamping mechanism 100 at the loading position 302 and the clamping position 301. Take a rectangular glass plate 310 with three clamping positions 301 as an example, the test mechanism 200 and the clamping mechanism 100 are located at the four corners of the glass. The clamping mechanism 100 is located at the corners of three glass plates 310, and the test mechanism 200 is located at the corner of one glass plate 310.

[0104] S3: Adjust the second flexible plate 103 of the clamping plate set 113 of the clamping mechanism 100 and the supporting member 211 of the testing mechanism 200 to the same height.

[0105] S4: Install instruments such as jacks for leveling the glass plate 310, and install measuring instruments such as displacement meters and strain gauges.

[0106] S5: After the glass plate 310 is leveled, the leveling instrument is removed to obtain the actual initial shape of the glass plate 310 under the action of gravity.

[0107] S6: The third lifting module 213 is used to slowly and uniformly lower the height of the support plate 2110. At this time, the height of the plate corner of the glass plate 310 also decreases due to gravity, and the glass is cold-bent. The actual value of the reaction force of each plate corner point of the glass plate 310 increases with the cold-bending displacement; when there are multiple supporting members 211, the multiple supporting members 211 are synchronously lowered.

[0108] S7: When the reaction force value of the supporting member 211 is reduced to 0, the corresponding supporting member 211 is further lowered or removed through the third lifting module 213, so that the lowered height of the supporting member 211 is greater than the cold bending displacement estimated by the test, thereby achieving the avoidance of the supporting member 211.

[0109] S8: The second lifting module 222 controls the caulking head 223 to descend in the first stage until it contacts the surface of the glass plate 310. Then, the second stage of caulking is performed, and the caulking head 223 is lowered at a constant speed until the cold bending displacement reaches the design value or meets the test requirements; when there are multiple loading mechanisms, the loading speeds of the multiple caulking heads 223 should be kept consistent and the loading should be carried out synchronously to complete the test.

[0110] Among them, the number of clamping mechanisms 100 affects the initial shape of the glass plate 310 under the action of gravity, and the number of clamping mechanisms 100 needs to be determined according to the requirements of the positive and negative Gaussian curvature of the glass plate 310. The movement rate of the supporting member 211 or the glue pressing head 223 should be kept within the static loading range.
