Description

Technical Field

[0001] This invention relates to the field of tempered glass manufacturing technology, and in particular to a multi-directional bending mechanism for tempered glass bending and its application method. Background Technology

[0002] The glass bending and tempering process is a common process for producing curved glass. Compared with the conventional hot bending process, it allows for rapid cooling and tempering after the glass is formed, which significantly improves the strength of the glass. Typically, to further enhance the strength and safety of the glass, a bottom layer of curved tempered glass and a top layer of curved tempered glass are prepared and then bonded together with an interlayer adhesive film to form curved tempered laminated glass. This process combines the rigidity of tempered glass with the safety of laminated glass, making it widely used in various buildings, transportation vehicles, and special-operation equipment.

[0003] The existing invention patent with authorization announcement number CN101175702B discloses a glass plate bending table and a method for bending a glass plate. It uses a primary starting mechanism to move a mold support linkage device to provide glass plate bending with a constant radius and uses a control linkage detachable connector, which allows a secondary starting mechanism to provide glass plate bending independently of the movement of the linkage device on the other side of the detachable connector.

[0004] The technical solution disclosed above is a very mature glass bending and tempering preparation equipment. It relies on upper and lower molds that can change curvature to bend the glass so as to prepare curved glass with different curvatures, or to make a single curved glass have multiple parts with different curvatures. Currently, this type of glass bending and tempering equipment cannot produce bidirectional curved glass because the upper and lower molds can only bend to the same side. That is, although curved glass can have multiple parts with different curvatures, the concave surfaces of the corresponding curved parts face the same side, which limits its application. In addition, although there is a process that uses a fixed lower mold in conjunction with a moving upper mold for hot bending of glass, it is difficult to achieve rapid cooling and tempering of the glass, resulting in lower glass strength. Moreover, each time curved glass with different curvatures is produced, the corresponding lower and upper molds must be remade, resulting in excessively high application costs. Summary of the Invention

[0005] In view of this, the present invention proposes a multi-directional bending mechanism and its application method for glass bending and tempering preparation that can realize multi-directional bending tempered glass preparation with low application cost, so as to solve the problems that existing glass preparation equipment cannot realize multi-directional bending of glass and the application cost is too high.

[0014] On the other hand, the present invention provides a glass bending method, which utilizes the above-mentioned multi-directional bending mechanism for glass bending and tempering, and includes the following steps: S1. Adjust the height of a single guide roller group through the second drive mechanism to make the guide roller group be on the same plane; S2. The height of all guide roller groups relative to the frame is adjusted synchronously through the second drive mechanism; S3. The heated glass plate is conveyed into the guide roller assembly, with the glass plate located between the upper and lower guide rollers; S4. The second drive mechanism corresponding to the middle section of the glass plate is activated. This second drive mechanism forms a drop with the guide roller group, first bending the middle section of the glass plate. During this process, the first drive mechanism drives the upper guide roller to move to the lower guide roller to clamp the glass plate. Then, the second drive mechanisms on both sides act synchronously to bend the glass plate to the side until it is bent to both ends of the glass plate to form an arc or undulating curved glass. S5.

[0015] Based on the above technical solutions, preferably, during the bending of the glass plate, the distance between the upper and lower guide rollers in the guide roller group is corrected by the first driving mechanism so that the distance between the upper and lower guide rollers in all guide roller groups is the same.

[0016] The multi-directional bending mechanism and its application method for glass bending and tempering of the present invention have the following advantages over the prior art: (1) By setting up several guide roller groups, after adjusting the drop of the guide roller groups, an arc-shaped channel will be formed between the upper and lower guide rollers. When the glass plate enters, it can form a curved structure with the drop of the guide roller groups, thereby realizing the bending of the glass. At the same time, since each guide roller group is set independently, the drop adjustment is flexible, which is conducive to the preparation of multi-directional curved glass, such as wavy curved glass. This gives it a good range of applications. Since no specific mold needs to be prepared, the application cost will not be too high. (2) By setting the first driving mechanism, the distance between the upper guide roller and the lower guide roller in the same guide roller group can be adjusted, which is beneficial to make the mechanism applicable to the bending preparation of glass of different thicknesses, and to ensure that the upper guide roller and the lower guide roller are in contact with the glass at the same time; by setting the third driving mechanism, all the upper guide rollers can be moved synchronously so that the upper guide rollers are separated from the glass, and a channel for curved glass output is left between the upper guide roller and the lower guide roller, which effectively improves the convenience of application; (3) By setting slide rails, bearing seats and drive motors in the guide roller group, it is convenient to guide the upper guide roller and the lower guide roller when they move, thereby ensuring the stability of movement. In addition, the drive motor in this mechanism is set as a moving structure, which not only does not interfere with the drop adjustment of the guide roller group, but also facilitates the rotation of the lower guide roller, thus making it easier to output curved glass. (4) By setting ribs on the roller body of the lower guide roller, the glass can be better supported, and during rapid cooling, the grooves formed by adjacent ribs are conducive to airflow, so as to ensure that the prepared curved glass is cooled evenly, thereby improving the tempering performance of the glass; at the same time, a variable diameter frame is set in the lower guide roller, which makes the lower guide roller have different diameters, which is conducive to better support of the glass, so as to ensure the quality of the preparation of curved glass. (5) The variable diameter frame is equipped with an eccentric arc plate, a connecting rod, a counterweight bar and a connecting frame. The eccentric arc plate and the connecting frame facilitate the connection and assembly with the roller body and the baffle. By rotating the lower guide roller, the angle can be changed, which can change the diameter of the side of the lower guide roller supporting the glass, which is beneficial to change the support position of the glass and better fit the glass. At the same time, a counterweight bar is provided on the eccentric arc plate, which can apply a force to the eccentric arc plate to resist the baffle, which is beneficial to further ensure the compactness of the connection between the variable diameter frame and the roller body. (6) By setting up a detection component, the laser can output laser light to cooperate with the laser target to receive the light signal, thereby leveling several lower guide rollers, which helps to ensure the preparation accuracy of curved glass.

[0024] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples.

Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0025] like Figures 1-10As shown, the multi-directional bending mechanism for glass bending and tempering preparation of the present invention includes a guide roller group 1, a frame 2, a first drive mechanism 3, a second drive mechanism 4, a third drive mechanism 5, a detection component 6, and a functional component 7.

[0026] like Figures 1-3 As shown, the guide roller group 1 includes an upper guide roller 11 and a lower guide roller 12 arranged opposite to each other, and several guide roller groups 1 are arranged side by side; the upper guide roller 11 and the lower guide roller 12 are both slidably engaged with the frame 2; the first drive mechanism 3 connects the upper guide roller 11 and the lower guide roller 12 in a guide roller group 1, and the first drive mechanism 3 is used to adjust the distance between the upper guide roller 11 and the lower guide roller 12; As described above, in the guide roller group 1, a channel for glass to pass through is formed between the upper guide roller 11 and the lower guide roller 12. Thus, after several guide roller groups 1 are arranged side by side, when the heated glass plate is placed on the lower guide roller 12, and the height difference of several guide roller groups 1 is adjusted, the glass plate located between the upper guide roller 11 and the lower guide roller 12 will bend and deform, thereby forming curved glass. Since the guide roller group 1 is provided with several, it can form an undulating flow channel, thereby enabling the preparation of curved glass with a multi-directional bending structure. Among them, the guide roller group 1 and the frame 2 are configured with a sliding fit mechanism, so as to ensure the stability of the operation when adjusting the drop of adjacent guide roller groups 1; The first drive mechanism 3 is used to adjust the distance between the upper guide roller 11 and the lower guide roller 12 in the same guide roller group 1 to facilitate the entry and exit of glass.

[0027] like Figure 1 and Figure 3 As shown, the second drive mechanism 4 is mounted on the frame 2, and the second drive mechanism 4 is used to adjust the position of a single guide roller group 1; As described above, the second drive mechanism 4 is mounted on the frame 2. By connecting the movable end of the second drive mechanism 4 to the guide roller group 1, the guide roller group 1 can be driven to move up and down, thereby achieving drop adjustment.

[0028] like Figure 3 As shown, the third drive mechanism 5 is used to synchronously adjust the position of the upper guide roller 11 in all guide roller groups 1; As described above, the third drive mechanism 5 is also mounted on the frame 2, and the third drive mechanism 5 is used to drive the upper guide roller 11 to move. In this way, after the curved glass is formed, the position of the upper guide roller 11 can be adjusted separately so that the upper guide roller 11 is away from the lower guide roller 12, thereby avoiding interference and facilitating the output of the prepared curved glass. Specifically, the third drive mechanism 5 can drive the upper guide rollers 11 of all guide roller groups 1 to move synchronously, thereby improving the efficiency of operation.

[0029] like Figure 3 and Figure 6 As shown, the first drive mechanism 3 is set corresponding to the guide roller group 1. The first drive mechanism 3 includes an upper pulley 31, a lower pulley 32, a cable 33, and a telescopic component 34. The upper pulley 31 is set at the top of the frame 2, and all the upper pulleys 31 in the first drive mechanism 3 are connected in series by a rotating shaft. The lower pulley 32 is set in the middle of the frame 2, and the lower pulley 32 is lower than the lower guide roller 12. One end of the cable 33 is connected to the upper guide roller 11, and the other end of the cable 33 passes around the upper pulley 31 and the lower pulley 32 and is connected to the lower guide roller 12. The telescopic component 34 is set in the middle section of the cable 33. The third drive mechanism 5 is set on the frame 2, and the movable end of the third drive mechanism 5 is connected to the upper pulley 31. As described above, the first drive mechanism 3 is used to adjust the distance between the upper guide roller 11 and the lower guide roller 12 in a single guide roller group 1. At the same time, the components of the first drive mechanism 3 also cooperate with the second drive mechanism 4 to realize the height adjustment of the guide roller group 1 relative to the frame 2, and cooperate with the third drive mechanism 5 to perform the height adjustment of all upper guide rollers 11. Specifically, in the first drive mechanism 3, the upper guide roller 11 and the lower guide roller 12 are connected by a cable 33. Since the cable 33 is supported by the upper pulley 31 and the lower pulley 32, and the telescopic member 34 is located in the middle of the cable 33, the lower guide roller 12 is fixed by the traction of the second drive mechanism 4. Therefore, when the movable end of the telescopic member 34 extends, the upper guide roller 11 will move closer to the lower guide roller 12, and when the movable end of the telescopic member 34 retracts, the upper guide roller 11 will move away from the lower guide roller 12. In this way, the distance between the upper guide roller 11 and the lower guide roller 12 can be adjusted. When the second drive mechanism 4 is activated, when the second drive mechanism 4 lifts the lower guide roller 12, the upper guide roller 11 will rise synchronously due to the traction of the cable 33. When the movable end of the second drive mechanism 4 is lowered, the upper guide roller 11 will descend synchronously with the lower guide roller 12. When the third drive mechanism 5 is activated, its movable end extends, causing the upper pulley 31 to move upward. Under the traction of the cable 33, the upper guide roller 11 is simultaneously lifted, and vice versa. At the same time, since all the upper pulleys 31 in the first drive mechanisms 3 are connected in series by a rotating shaft, all the upper pulleys 31 will move upward synchronously when the third drive mechanism 5 is activated. This allows the position of all the upper guide rollers 11 to be adjusted synchronously, which helps to move the upper guide rollers 11 away from the lower guide roller 12, thus facilitating the output of the formed laminated glass. Therefore, the number of third drive mechanisms 5 does not need to correspond to the number of guide roller groups 1. Instead, a small number of third drive mechanisms 5 are used as driving components, and all the upper pulleys 31 are moved synchronously by the rotating shafts used for series connection.

[0030] like Figure 6As shown, the guide roller assembly 1 also includes a slide rail 13, a bearing housing 14, and a drive motor 15. The slide rail 13 is mounted on the frame 2. The bearing housing 14 and the drive motor 15 are both slidably engaged with the slide rail 13. The upper guide roller 11 is rotatably connected to the bearing housing 14. The lower guide roller 12 is connected to the output end of the drive motor 15. One end of the cable 33 is connected to the bearing housing 14, and the other end of the cable 33 is connected to the drive motor 15. As described above, the slide rail 13 is mounted on the frame 2 and is used for sliding guidance of the upper guide roller 11 and the lower guide roller 12. The upper guide roller 11 is used to cooperate with the lower guide roller 12 to form curved glass. The upper guide roller 11 is not used for conveying curved glass. Therefore, the upper guide roller 11 can be slidably engaged with the slide rail 13 through the bearing seat 14. Setting the upper guide roller 11 as a rotatable structure is beneficial to adapt to the friction generated when the glass is bent, so that the upper guide roller 11 can rotate adaptively and prevent friction from affecting the forming quality of the glass. In some embodiments, the upper guide roller 11 may not adopt a rotating roller structure, but rather a block-shaped structure, which is selected according to specific manufacturing requirements; The lower guide roller 12 is not only used to cooperate with the upper guide roller 11 to complete the preparation of the curved surface of the glass, but also to be used for the output of the glass. Therefore, the end of the lower guide roller 12 is slidably engaged with the slide rail 13 through the drive motor 15. The drive motor 15 can be installed at only one end of the lower guide roller 12, and the other end can be supported by the bearing seat 14. In this way, after the curved glass is prepared and the upper guide roller 11 moves away from the lower guide roller 12, the lower guide roller 12 can be rotated by the drive motor 15 to output the prepared curved glass. The end of the cable 33 can be connected to the bearing seat 14 and the drive motor 15 to facilitate the movement of the upper guide roller 11 and the lower guide roller 12.

[0031] like Figure 1 and Figure 6 As shown, the frame 2 includes a base plate 21 and upright plates 22. Four upright plates 22 are arranged side by side on the base plate 21, with two upright plates 22 at each end of the guide roller group 1. An upper pulley 31 and a lower pulley 32 are clamped and disposed between two adjacent upright plates 22, and the upper pulley 31 is slidably connected to the upright plate 22. A third drive mechanism 5 is clamped and disposed between two adjacent upright plates 22. A second drive mechanism 4 is disposed on the frame 2, and the movable end of the second drive mechanism 4 is rotatably connected to the lower guide roller 12.

[0032] As described above, the frame 2 is configured as two parts: a base plate 21 and a vertical plate 22. The vertical plate 22 has four pieces on the base plate 21 and is distributed at both ends of the guide roller group 1 to support the first drive mechanism 3 and the third drive mechanism 5 on both sides. In the illustrated structure, a single upright plate 22 is set as several blocks arranged side by side. In actual application, the upright plate 22 can be set as a single individual without being divided. For the sake of assembly convenience, a single upright plate 22 can also be divided into several blocks for easy assembly. The wheel frame for fixing the upper pulley 31 and the lower pulley 32 is directly clamped between two adjacent upright plates 22 and fixed with fasteners. The third drive mechanism 5 is also clamped between two adjacent upright plates 22, and the movable end of the third drive mechanism 5 is connected to the wheel frame of the upper pulley 31. Specifically, in order to prevent the upper pulley 31 from twisting relative to the third drive mechanism 5, the upper pulley 31 and the frame 2 are set as a sliding fit structure. Specifically, the wheel frame used to install the upper pulley 31 is slidably connected to the frame 2. This structure can be achieved by opening a sliding groove on the frame 2 and then slidingly assembling the wheel frame. The second drive mechanism 4 is mounted on the base plate 21 and is used to drive the guide roller group 1 to move up and down. Specifically, since the lower guide roller 12 is configured as a rotating structure, the movable end of the second drive mechanism 4 is connected to the lower guide roller 12 in a rotating manner to avoid transmission interference.

[0033] like Figures 9-10 As shown, the lower guide roller 12 includes a roller body 121, ribs 122, baffles 123, and a diameter changer 124. The end of the roller body 121 is connected to the drive motor 15. Several ribs 122 are arranged side by side on the roller body 121, and a groove 101 is formed between adjacent ribs 122. The baffles 123 are fixedly arranged in the grooves 101. The diameter changer 124 is engaged in the grooves 101 and is connected to the baffles 123. The diameter changer 124 is used to change the diameter of the lower guide roller 12. As described above, in the structure of the lower guide roller 12, the roller body 121 is provided with several ribs 122, which can better support the glass. During rapid cooling, the grooves 101 formed by adjacent ribs 122 are conducive to airflow, so as to ensure that the prepared curved glass is cooled evenly, thereby improving the tempering performance of the glass. Specifically, the upper guide roller 11 can also adopt this mechanism with ribs 122; Meanwhile, in this structure, a variable diameter frame 124 is provided in the lower guide roller 12, which allows the lower guide roller 12 to have different diameters. Thus, the lower guide roller 12 can change the position of supporting the glass by rotating, which is beneficial to better support the glass and ensure the quality of the curved glass preparation. Specifically, such as Figure 13As shown, after the drop is changed by several guide roller groups 1, the arc-shaped distance between the two support points of the glass will increase. If the lower guide roller 12 is a regular cylindrical structure, its support point on the glass will not change no matter how it is rotated. After the position of the variable diameter frame 124 is switched by rotation, the support point of the lower guide roller 12 can be changed by the variable diameter frame 124, so that it can be applied to the preparation needs of different curved glass. Furthermore, in order to accommodate the change in support position caused by the variable diameter frame 124 in the lower guide roller 12, the upper guide roller 11 can also be driven by a motor and is also equipped with a variable diameter frame 124.

[0034] like Figure 10 As shown, the variable diameter frame 124 includes an eccentric arc plate 1241, a connecting rod 1242, a counterweight bar 1243, and a connecting frame 1244. Several eccentric arc plates 1241 are arranged side-by-side, each snapped into a slot 101, and connected to a baffle 123 via fasteners. The connecting rod 1242 connects several eccentric arc plates 1241 in series. The counterweight bar 1243 is disposed on several eccentric arc plates 1241, and is located at the end of the eccentric arc plate 1241 furthest from the baffle 123. One end of the connecting frame 1244 is connected to the connecting rod 1242, and the other end is connected to the roller body 121. As described above, the variable diameter frame 124 is provided with several eccentric arc plates 1241. The eccentric arc plates 1241 are engaged in the slots 101 formed by two adjacent ribs 122 and are fastened to the baffle 123 by fasteners. Thus, when the lower guide roller 12 is rotated, due to the setting of the eccentric arc plates 1241, the lower guide roller 12 can change the distance between itself and the upper guide roller 11. At the same time, the support point of the lower guide roller 12 on the glass will change, which is suitable for the preparation of glass with different curvatures. Among them, several eccentric arc plates 1241 are connected in series by connecting rods 1242, which makes it convenient to insert and fix them to the roller body 121, and also facilitates the installation of the connecting frame 1244, thereby further ensuring the stability of the variable diameter frame 124 installation. Furthermore, counterweights 1243 are provided on several eccentric arc plates 1241. Since the variable diameter frame 124 is connected to the roller body 121 through the connecting frame 1244, the weight will exert a force on the eccentric arc plate 1241 to resist the baffle 123, which helps to further ensure the compactness of the connection between the variable diameter frame 124 and the roller body 121. Specifically, the arc surface of the eccentric arc plate 1241 is tangent to the arc surface of the rib plate 122 to ensure a smooth transition; Specifically, due to the setting of the eccentric arc plate 1241, when the lower guide roller 12 rotates to output the curved glass, the curved glass may experience bumping. At this time, it is necessary to control the output speed of the curved glass. Furthermore, the height of all guide roller groups 1 can be adjusted so that the top surface of all lower guide rollers 12 in all guide roller groups 1 forms a continuous slope, so that the glass can slide out automatically.

[0035] like Figures 3-5 As shown, one detection component 6 is provided in each guide roller group 1. The detection component 6 includes a fixed frame 61, a laser 62 and a laser target 63. The fixed frame 61 is mounted on the drive motor 15; the laser 62 is mounted on the fixed frame 61 and is located at the end of the frame 2; the laser target 63 is mounted on the fixed frame 61 of the other detection components 6. The fixed frame 61 is provided with a through hole 601, the laser target 63 is located in the through hole 601, and the through hole 601 is reserved with a laser channel. As described above, the detection component 6 is used to correct the parallelism of several lower guide rollers 12 to ensure the quality of curved glass preparation. Specifically, among the several guide roller groups 1, only the drive motor 15 of the guide roller group 1 at the end of the frame 2 is equipped with a fixed frame 61 with a laser 62, while the drive motor 15 of the other guide roller groups 1 is equipped with a fixed frame 61 with a laser target 63. In this way, during the calibration, the calibration is performed at the far end, the middle guide roller groups 1 are all lowered, and the laser 62 emits a detection laser towards the laser target 63 equipped on the farthest guide roller group 1. After the beam is detected, the guide roller group 1 that is close to a certain position is raised. The above steps are repeated until all calibrations are completed. Furthermore, a detection component 6 is also provided on the bearing seat 14 of the upper guide roller 11 to correct the parallelism of all upper guide rollers 11 after the lower guide roller 12 is corrected. At the same time, the height of the upper guide roller 11 during detection is adjusted synchronously by the first drive mechanism 3 until the light beam can be detected. This helps to eliminate errors caused by loosening or tensioning of the cable, so as to further ensure the glass preparation accuracy. Specifically, the through hole 601 is provided with a laser channel, that is, the laser target 63 does not completely cut off the through hole 601, but leaves a part to form a laser channel for the detection laser to pass through. In this way, the guide roller group 1 does not need to be lowered by a large distance, but only fine-tuned to allow the laser to pass through, and then each one can be detected.

[0036] like Figure 7 and Figure 8 As shown, functional component 7 includes air duct 71, pulley 72, synchronous belt 73, and drive component 74. The air duct 71 is arranged parallel to the lower guide roller 12, and the gap between two adjacent lower guide rollers 12 is corresponding to the air duct 71. The end of the air duct 71 is slidably engaged with the frame 2. The air duct 71 is connected to an air supply assembly. The pulley 72 is arranged on the air duct 71. The synchronous belt 73 connects the pulleys 72 on two adjacent air ducts 71. The drive component 74 is arranged on the frame 2, and the movable end of the drive component 74 is rotatably connected to the air duct 71. As described above, the functional component 7 is set as an air-cooling assembly, wherein the air duct 71 corresponds to the gap between two adjacent lower guide rollers 12. Thus, after the curved glass is formed, air can be supplied through the air duct 71 to rapidly cool and temper the glass. The system includes several ducts 71, with an air outlet on the side of the duct 71 corresponding to the glass. To address the issue of glass breakage, pulleys 72 and synchronous belts 73 are provided to connect the ducts 71. By connecting the pulleys 72 at the ends to a motor, all ducts 71 can be rotated. In the event of glass breakage, the air outlets of the ducts 71 can be adjusted to face downwards to prevent glass shards from entering the ducts 71. Among them, the drive component 74 is used to drive the air duct 71 to move up and down, so as to adapt to the large height changes of the guide roller group 1; Specifically, other components required for tempering curved glass can also be added to the installation location of functional component 7.

[0037] Specifically, the first drive mechanism 3, the second drive mechanism 4, the third drive mechanism 5, and the drive component 74 can be linear drive components such as electric push rods, cylinders, and hydraulic cylinders.

[0038] The glass bending method of the present invention, using the above-described multi-directional bending mechanism for glass bending and tempering, includes the following steps: S1. Adjust the height of a single guide roller group 1 by the second drive mechanism 4 so that the guide roller group 1 is on the same plane; S2. The height of all guide roller groups 1 relative to the frame 2 is adjusted synchronously through the second drive mechanism 4. S3. The heated glass plate is conveyed into the guide roller assembly 1, with the glass plate positioned between the upper guide roller 11 and the lower guide roller 12; at this point, see [reference needed]. Figure 11 The state shown; S4. The second drive mechanism 4 corresponding to the middle section of the glass plate is activated. This part of the second drive mechanism 4 forms a drop corresponding to the guide roller group 1, first bending the middle section of the glass plate. During this process, the first drive mechanism 3 drives the upper guide roller 11 to move to the lower guide roller 12 to clamp the glass plate. Then, the second drive mechanisms 4 on both sides act synchronously to bend the glass plate laterally until it is bent to both ends of the glass plate to form an arc-shaped or undulating curved glass surface. At this time, see Figure 12 and Figure 13 The state shown; S5. Rapid cooling and tempering of curved glass using a cooling assembly; S6. Simultaneously raise all upper guide rollers 11 using the third drive mechanism 5 until the distance between the upper guide rollers 11 and the lower guide rollers 12 is greater than the distance between the highest and lowest points of the curved glass; at this point, refer to... Figure 14 The state shown; S7. Through the second drive mechanism 4, synchronously adjust the height of all guide roller groups 1 relative to the frame 2 until all lower guide rollers 12 are level; at this time, see Figure 15 The state shown; S8. The third drive mechanism 5 is used to synchronously lift all the upper guide rollers 11 again until all the upper guide rollers 11 no longer interfere with the transfer of the curved glass.

[0039] Specifically, to ensure the accuracy of the preparation, the distance between the upper guide roller 11 and the lower guide roller 12 in the guide roller group 1 is corrected by the first drive mechanism 3 between the bending of the glass plate, so that the distance between the upper guide roller 11 and the lower guide roller 12 in all guide roller groups 1 is the same. This is specifically done by the detection component 6.

[0040] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
