[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0028] Example 1: The specific structure of this utility model is as follows:
[0029] Please refer to the appendix. Figure 1-3 The present invention relates to a curved glass clamping mechanism, comprising a base plate 1, a movable part, a contoured vacuum adsorption plate 2, and a tensioning mechanism with shrinking and stretching functions.
[0030] The movable part is arranged along the first direction of the base plate 1 and can move along the first direction. The movable part has a first locking area that can lock one end of the curved glass. Guide rails 3 are provided on both sides of the base plate 1 in the first direction. The movable part is a connecting block 5, which is slidably connected to the two guide rails 3 by a slider. The connecting block 5 has a groove in the middle area of one end facing the contour vacuum adsorption plate 2.
[0031] The first locking area includes a contoured locking block 7 disposed at the slot. The outer end of the contoured locking block 7 has a crescent-shaped arc surface with a downward chamfer, and the surface formed after chamfering forms an acute angle with the upper surface of the contoured locking block 7. The upper surface of the contoured locking block 7 is flush with the upper surface of the connecting block 5, and its crescent-shaped arc surface protrudes outward from the slot on both sides.
[0032] The contouring block 7 is a detachable structure with an adjustable position. The contouring block 7 stabilizes the position of the curved surface CG throughout the bonding process, improving bonding quality.
[0033] The contour-following vacuum adsorption plate 2 is detachably mounted on the surface of the base plate 1. It has a second locking area capable of holding the other end of the curved glass. The first and second locking areas face each other. The contour-following vacuum adsorption plate 2 has a negative pressure chamber, and the second locking area has a negative pressure hole communicating with the negative pressure chamber. The second locking area is a circular groove 21 with a notch, which faces the first locking area. The sidewall of the circular groove 21 forms an acute angle with its bottom surface. Multiple negative pressure holes are provided, arranged on the bottom surface of the circular groove 21. An air connector 8 is connected to the side of the contour-following vacuum adsorption plate 2, communicating with the negative pressure chamber. An air inlet is provided on the other side of the contour-following vacuum adsorption plate 2, communicating with the negative pressure chamber. Figure 1 The right side of the contour vacuum adsorption plate 2. The air connector 8 connects to an external air path to provide a vacuum for the contour vacuum adsorption plate 2.
[0034] The contouring block 7 and the contouring vacuum adsorption plate 2 can be replaced according to the size and radius of the curved glass to adapt to the outer contour of the curved glass, thus having a wider range of applications.
[0035] The tensioning mechanism has both contraction and extension functions. One end of the tensioning mechanism is connected to a movable part, and the other end is fixed to the base plate 1 by a first fixing member 6. The contraction direction of the tensioning mechanism satisfies the movement from the first locking area to the second locking area. The connecting block 5 has second fixing members connected to both sides of its end facing the contoured vacuum adsorption plate 2. There are two first fixing members 6, located on both sides of the contoured vacuum adsorption plate 2 and extending along the two guide rails 3. The first fixing members 6 and the second fixing members have the same structure and both have side-entry hook holes. The tensioning mechanism has two sets, each set equipped with a spring 4. The spring 4, along with the first fixing member 6 and the second fixing member on the same side, form a tensioning mechanism. In one set of tensioning mechanisms, one end of the spring 4 hooks into the side-entry hook hole of the first fixing member 6, and the other end hooks into the side-entry hook hole of the second fixing member. The spring 4 pulls the contoured locking block 7 along the guide rail 3 with its own elastic force to perform a tensioning action.
[0036] When the curved surface CG is placed into the circular groove 21, the contraction of the two springs 4 will lock the crescent-shaped arc surface of the contour block 7 in place of the curved surface CG, preventing the curved surface CG from shifting.
[0037] In summary, this invention, based on the principle of the curved surface CG being firmly held by the contour-following vacuum adsorption plate, incorporates a clamping mechanism that further ensures the positional accuracy of the curved surface CG. The curved glass clamping mechanism of this invention optimizes the curved surface bonding structure, reduces the space occupied, and is applicable to more flexible products, effectively solving the problems of easy misalignment and low bonding accuracy in curved surface bonding. Furthermore, the contour-following block 7 and the contour-following vacuum adsorption plate 2 of this invention can be replaced according to the size and radius of curvature of the curved glass, thus broadening its applicability.
[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
