Specifically, the bottom of both ends of the lower roller mechanism 504 refers to the bottom of both ends in the length direction of the roller.

[0043] Preferably, both ends of the plurality of rollers are respectively connected with a lower elastic member 503. The lower elastic member 503 is preferably an elastic plate. In other embodiments, the lower elastic member 503 can be an elastic rod, or the lower elastic member 503 comprises a plurality of spring wires which are connected with the lower roller mechanism 504 and the lower end arc changing mechanism 502 as a whole.

[0044] Preferably, the ends of all the conveying rollers are respectively connected with the lower elastic member 503 through first bearing seats, the bottom ends of all the first bearing seats are fixedly connected with the lower elastic member 503, and the ends of the conveying rollers are rotatably connected with the first bearing seats; alternatively, the bottom ends of the first bearing seats can be clamped on the lower elastic member, and the first bearing seats and the lower elastic member can slide relative to each other.

[0045] The lower end arc changing mechanism 502 is provided with a plurality of lower connectors in the length direction, the bottoms of the plurality of lower connectors are fixed on the lower end arc changing mechanism 502, at least one of the plurality of lower connectors is fixedly connected with the lower elastic member 503, and the remaining lower connectors are slidably clamped on the length direction edge of the lower elastic member 503. The purpose of the arrangement is to meet the need that the lower elastic member 503 is curved into different radii along with the lower end arc changing mechanism 502 on the basis of fixing the lower elastic member 503, because the other positions of the lower elastic member 503 will slide relative to the lower end arc changing mechanism 502 at this time. The connection structure of the lower elastic member 503 and the conveying roller and the lower elastic member 503 and the lower end arc changing mechanism is stable in connection and convenient in installation. The lower connector and the first bearing seat are parts for corresponding connection, the specific structure can be flexibly designed, the lower connector for fixedly connecting the lower elastic member can be different from the lower connector for slidably clamping the lower elastic member, and better corresponding effect can be achieved. Further preferably, the lower connector fixedly connected with the lower elastic member 503 is one, which is located at the sheet feeding end or the sheet discharging end of the lower end arc changing mechanism 502, so that the sheet feeding position or the sheet discharging position is more conveniently adjusted. Preferably, the lower connector fixedly connected with the lower elastic member 503 is a fixed plate, and the remaining lower connectors can be L-shaped or T-shaped sliders. It should be noted that the lower connector can also be formed by splicing a plurality of sub-pieces.

The lower connecting plate 5021 is a T-shaped plate, a T-shaped plate, a trapezoidal plate or a triangular plate.

[0048] The forming equipment corresponds to the intermediate connecting piece of the lower end portion variable curvature mechanism 502 and the lower roller way mechanism 504 by arranging the lower elastic member 503 in the lower forming mechanism 5, so that the installation of the lower roller way mechanism 504 is not dependent on the lower connecting plate 5021 of the corresponding variable curvature mechanism, specifically, the center distance of the adjacent two conveying roller ways is less than the center distance of the adjacent two lower pin shafts 5022, so that the fine roller way, the small interval roller way installation arrangement can be realized, the interval of the roller ways is reduced, the forming precision of the curved glass after forming is improved, the straight edge of the curved glass is reduced, and the profile precision of the curved glass is improved.

[0049] Further, the diameter of the conveying roller way is 15-30 mm, and the center distance between the adjacent two conveying roller ways is 20-40 mm. The diameter range of the conveying roller way and the center distance range between the adjacent two conveying roller ways are preferred two mutually matched parameter ranges, and in the range, the use of the two ranges can maximize the reduction of the straight edge of the glass, improve the forming quality of the glass, and take into account the rigidity of the roller way and the durability of the equipment. Specifically, the diameter of the conveying roller way is 15 mm, and the center distance between the adjacent two conveying roller ways is 20 mm or 22 mm. Alternatively, the diameter of the conveying roller way is 30 mm, and the center distance between the adjacent two conveying roller ways is 36 mm or 40 mm.

[0050] Embodiment 2

[0051] As shown in Figure 3 , Figure 4 based on embodiment 1, further comprising an upper forming mechanism 4; the upper forming mechanism 4 comprises an upper end portion variable curvature mechanism 401, an upper elastic member 402 and an upper pressure roller mechanism 403; the upper pressure roller mechanism 403 is provided with an upper elastic member 402 at the top of each end, and the upper elastic member 402 is connected with the upper end portion variable curvature mechanism 401 at the top; at least one end of the upper end portion variable curvature mechanism 401 is connected with an upper pulling assembly; the upper pressure roller mechanism 403 comprises a plurality of upper pressure rollers, the upper end portion variable curvature mechanism 401 comprises a plurality of staggered upper connecting plates 4011, two adjacent upper connecting plates 4011 are connected by an upper pin shaft 4012, and the center distance between the adjacent two upper pressure rollers is less than the center distance between the adjacent two upper pin shafts 4012.

[0052] Specifically, in this example, the upper elastic member 402 is preferably an elastic plate, which is easy to install and connect. In other embodiments, the upper elastic member 402 can be an elastic rod, or the upper elastic member 402 comprises a plurality of spring steel wires, which are connected to the upper pressure roller mechanism 403 and the upper end portion variable curvature mechanism 401 as a whole. The above structures can all have the same effect.

[0053] Preferably, all the upper pressing roller ends are connected with the upper elastic member 402 through the second bearing seat respectively, the top of all the second bearing seats is fixedly connected with the upper elastic member 402, and the end of the upper pressing roller is rotatably connected with the second bearing seat; alternatively, the top of the second bearing seat can be clamped on the upper elastic member, and the second bearing seat and the upper elastic member can slide relative to each other. Alternatively, the top of part of the second bearing seats in all the second bearing seats is fixedly connected with the upper elastic member, and the top of the first bearing seat is clamped on the lower elastic member.

[0054] Preferably, the upper end arc changing mechanism 401 is provided with a plurality of upper connectors, the bottom of the plurality of upper connectors is fixed on the upper end arc changing mechanism 401, and at least one upper connector in the plurality of upper connectors is fixedly connected with the upper elastic member 402, and the remaining upper connectors are clamped on the edge of the upper elastic member 402 in the length direction and can slide relative to each other. The purpose of the arrangement is to meet the need that the upper elastic member 402 is bent into different radii with the upper end arc changing mechanism 401 on the basis of fixing the upper elastic member 402, because at this time the other positions of the upper elastic member 402 will slide relative to the upper end arc changing mechanism 401. The connection structure of the upper elastic member 402 and the upper pressing roller and the upper elastic member 402 and the upper end arc changing mechanism is stable in connection and convenient in installation. The upper connector and the second bearing seat are parts for corresponding connection, the specific structure can be designed flexibly, the upper connector for fixedly connecting the upper elastic member and the structure of the upper connector for being clamped on the upper elastic member and can slide relative to each other can be different, and the corresponding effect is better. Further preferably, one upper connector located at the sheet feeding end or the sheet discharging end of the upper end arc changing mechanism 401 is fixedly connected with the upper elastic member 402, which is more convenient for adjusting the sheet feeding position or the sheet discharging position. The upper connector is prior art, and will not be described in detail here. Preferably, the upper connector fixedly connected with the upper elastic member 402 is a fixed plate, and the remaining upper connectors can be selected to be L-shaped or T-shaped sliders. It should be noted that the upper connector can also be formed by splicing a plurality of sub-pieces.

[0055] The upper end arc changing mechanism 401 can also include one group of lower connecting plates 5021 or two groups of lower connecting plates 5021, which is selected according to the need for arc forming and the limitation of the overall device structure. The upper end arc changing mechanism 401 and the lower end arc changing mechanism can adopt different structures without any requirement, and generally speaking, the arc forming precision of the lower end arc changing structure has a greater influence on the forming precision of the curved glass, and the forming precision of the lower end arc changing mechanism 502 structure is higher than that of the upper end arc changing mechanism 401 structure.

[0056] Further, the upper forming mechanism 4 is matched with the lower forming mechanism 5. The upper forming mechanism 4 preferably also adopts the upper elastic member 402 to correspond to the intermediate connecting member of the upper end arc changing mechanism 401 and the upper pressure roller mechanism 403, so that the installation of the upper pressure roller mechanism 403 is not dependent on the upper connecting plate 4011 of the corresponding arc changing mechanism, thereby realizing the installation and arrangement of the thin roller bed and small spacing, and further improving the glass forming precision in cooperation with the lower forming mechanism 5.

[0057] In other embodiments, the upper forming mechanism 4 can also not adopt the above structure, but can adopt other deformable structures to realize cooperation with the lower forming mechanism 5.

[0058] Preferably, the diameter of the upper pressure roller is 15mm-30mm, and the center distance between adjacent two upper pressure rollers is 20mm-40mm. The diameter range of the upper pressure roller and the center distance range between adjacent two upper pressure rollers are preferred two mutually matched parameter ranges. In the range, the use in cooperation can minimize the straight edge of the glass and improve the glass forming quality, and the rigidity of the roller bed and the durability of the equipment are also considered. Specifically, the diameter of the upper pressure roller is 15mm, and the center distance between adjacent two upper pressure rollers is 20mm or 22mm. Alternatively, the diameter of the upper pressure roller is 30mm, and the center distance between adjacent two upper pressure rollers is 36mm or 40mm.

[0063] This forming equipment mounts multiple conveyor rollers from the lower roller conveyor mechanism above the lower end arc-changing mechanism in the lower forming mechanism, without relying on the hinged connection of the lower connecting plate of the corresponding arc-changing mechanism. The lower end arc-changing mechanism only serves as the basic arc-changing mechanism, while the lower roller conveyor mechanism serves to convey and form the glass. By lifting and changing the arc on the outside of the lower end arc-changing mechanism, the inner sides of the multiple conveyor rollers of the lower roller conveyor mechanism above it are driven to change the arc and form a forming surface with a smaller radius. It can also realize the installation and arrangement of fine rollers and small-pitch conveyor rollers. By reducing the roller spacing, the forming accuracy of the curved glass after forming is improved, the straight edges of the curved glass are reduced, and the contour accuracy of the curved glass is improved.

As another embodiment, they can also be disposed on the upper forming mechanism 4.

[0066] The slide plate 501 provides a sliding contact, ensuring that during the process of the lower forming mechanism 5 being lifted and curved and contacting the upper forming mechanism 4, and driving the upper forming mechanism 4 to curve, the position of the lower forming mechanism 5 being lifted and curved and contacting the upper forming mechanism 4 can slide relative to each other, and there will be no problem of the lower forming mechanism 5 and the upper forming mechanism 4 getting stuck or interfering with each other in some parts of the structure.

[0076] Embodiment 7

[0077] A high-precision glass forming method is applied to the high-precision glass forming equipment as described in embodiments 1-6.

[0078] Firstly, the end of the lower end arc changing mechanism is pulled to change the arc of the lower end arc changing mechanism, and the radius of the arc fitted by the plurality of lower pins in the lower end arc changing mechanism is R1; while the outer side of the lower end arc changing mechanism is changing the arc, the plurality of conveying roller beds arranged above the lower end arc changing mechanism are also changing the arc, and the radius of the forming surface fitted by the plurality of conveying roller beds after changing the arc is R2, R2 < R1; the center distance of the adjacent two conveying roller beds is smaller than the center distance of the adjacent two lower pins.

[0079] The glass forming method pulls the end of the lower end arc changing mechanism to make the lower end arc changing mechanism change the arc, and drives the lower roller bed mechanism arranged above the lower end arc changing mechanism to change into a forming surface with a smaller radius while the lower end arc changing mechanism changes the arc. The lower end arc changing mechanism only plays a role in basic arc changing, and the lower roller bed mechanism plays a role in conveying and forming glass. The conveying roller bed does not have to be attached to the hinge connection of the corresponding lower connecting plate of the arc changing mechanism. After changing the arc, the radius of the arc fitted by the plurality of lower pins is greater than the radius of the arc of the forming surface fitted by the plurality of conveying roller beds, and the fine roller bed and small-pitch roller bed installation arrangement can be achieved. By reducing the pitch between the roller beds, the forming precision of the curved glass after forming is improved, the straight edge of the curved glass is reduced, and the profile precision of the curved glass is improved.

[0080] Further, when a lower elastic member is arranged on a high-precision glass forming equipment, the lower elastic member serves as an intermediate connecting member of the lower end arc changing mechanism and the conveying roller bed. Firstly, the lower end arc changing mechanism changes the arc to drive the lower elastic member to change the arc, and simultaneously, the lower elastic member changes the arc to drive the plurality of conveying roller beds to change the arc. The lower end arc changing mechanism changes the arc to drive the lower elastic member to change the arc, and the lower elastic member changes the arc to drive the lower roller bed mechanism to change into a forming surface with a certain radius. The plurality of conveying roller beds of the lower roller bed mechanism have a unified installation basis through the elastic member. The arc precision of the forming surface fitted by the conveying roller beds after changing the arc is higher, and the curved glass forming quality is higher.

[0081] Further, the center of the forming surface fitted by the plurality of conveying roller beds coincides with the center of the arc fitted by the plurality of lower pins.

[0082] It should be noted that the two sides of the turnover frame refer to the left and right sides in the glass conveying direction.

[0083] While the preferred embodiments of the application have been described, those skilled in the art will be able to make additional variations and modifications without departing from the scope of the application. Therefore, the appended claims are intended to cover all such variations and modifications that come within the scope of the application. It is evident that those skilled in the art can make various changes and modifications of the application without departing from the spirit and scope thereof. It is therefore intended to embrace all such changes and modifications in a broad aspect of the application as can be allowed under the fair scope thereof and the scope of the following claims.
