Description

Technical Field

[0001] The present invention relates to the technical field of glass bending, and in particular to a glass bending device. Background Art

[0002] Traditional glass bending equipment generally adopts a rigid mold pressing process. This technical solution has many inherent defects, which seriously restricts the development of the glass processing industry. First, in terms of bending accuracy, due to the lack of dynamic adaptation ability between the rigid mold and the glass, local stress concentration is easily generated during the pressure application process, resulting in microcracks, scratches and even cracks on the glass surface, seriously affecting the product yield. Secondly, in terms of process adaptability, the finished product often has quality problems such as inconsistent bending angles and unnatural surface transitions. In the prior art, when the bending angle of the glass changes, the mold needs to be replaced, and the rigid mold pressing method cannot adapt to the glass deformation in real time, resulting in low finished product yield and limited production efficiency. In the softened state, the glass will sag due to its own weight or be subjected to external forces, which will produce unexpected deformation, and the rigid mold cannot adjust the force direction and contact surface shape in real time, which ultimately leads to defects such as bending angle deviation and surface distortion. Summary of the invention

[0003] The present invention proposes a glass bending device, which solves the problems of micro cracks, scratches and so on caused by stress concentration of traditional rigid molds by setting a deformation bending mechanism with flexible shape change.

The first drive mechanism and the second drive mechanism respectively control the deformation bending mechanism and the supporting and conveying assembly to achieve the coordination of the bending of the glass and the conveying connection when the glass arrives at the bending station. When the glass is bent, the supporting and conveying assembly actively detaches from the glass through the second drive mechanism to avoid interfering with the bending process of the glass, and the shape change section of the deformation bending mechanism moves along the bending direction of the glass to ensure a natural transition of the glass bending.

[0029] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. In order to make the above - mentioned objects, features, and advantages of the present application more obvious and understandable, many specific details are set forth in the following description for a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0030] Refer to Figures 1 - 14 , a glass bending device, including a frame 1 provided with a glass conveying section, and a deformation bending mechanism 3, a supporting and conveying assembly 4, a first driving mechanism 5, and a second driving mechanism 7 arranged on the frame 1; The deformation and bending mechanism 3 has a flexible shape change, and the deformation and bending mechanism 3 cooperates with the glass 6 to bend by changing its own shape; The first driving mechanism 5 is in transmission connection with the deformation and bending mechanism 3, and the second driving mechanism 7 is in transmission connection with the supporting and conveying assembly 4; The supporting and conveying assembly 4 is used to form a conveying connection with the output end of the glass conveying section to support the glass 6 outside the output end of the glass conveying section, and the second driving mechanism 7 drives the supporting and conveying assembly 4 to move away from the direction of the glass 6 when the glass 6 is bent, and the first driving mechanism 5 drives the shape-changing section of the deformation and bending mechanism 3 to move along the bending direction of the glass 6 and act on the glass 6 to achieve bending of the glass 6; After the glass 6 is bent, the first driving mechanism 5 drives the shape-changing section of the deformation and bending mechanism 3 to perform a reset operation.

[0031] By setting a deformation bending mechanism 3 with flexible morphological changes, the problems of micro cracks, scratches and so on caused by stress concentration of traditional rigid molds are solved. The deformation bending mechanism 3 can dynamically adapt to the bending deformation process of the glass 6, significantly improving the bending accuracy and yield. The first drive mechanism 5 and the second drive mechanism 7 respectively control the deformation bending mechanism 3 and the supporting conveying assembly 4 to achieve the coordination of the bending of the glass 6 and the conveying connection when the glass 6 arrives at the bending station. When the glass 6 is bent, the supporting conveying assembly 4 actively detaches from the glass 6 through the second drive mechanism 7 to avoid interfering with the bending process of the glass 6, and the morphological change section of the deformation bending mechanism 3 moves along the bending direction of the glass 6 to ensure that the bending transition of the glass 6 is natural. The reset operation function of the deformation bending mechanism 3 after the glass 6 is bent further improves the continuous operation efficiency of the equipment, and the overall technical solution has both high adaptability and automation level.

[0032] The glass bending equipment also includes a second bending mechanism 8 arranged on the frame 1. When the glass 6 is bent, the first driving mechanism 5 drives the shape-changing section of the deformation bending mechanism 3 to move toward the direction close to the second bending mechanism 8. When the glass 6 is bent, the glass 6 is limited between the deformation bending mechanism 3 and the second bending mechanism 8. The deformation bending mechanism 3 and the second bending mechanism 8 cooperate with the glass 6 as a whole to bend and form an L shape or an inverted L shape.

[0033] By adding the second bending mechanism 8 and forming an L-shaped or inverted L-shaped matching structure with the deformation bending mechanism 3, the two-way limiting and coordinated bending of the glass 6 are achieved. The first driving mechanism 5 drives the shape-changing section of the deformation bending mechanism 3 to approach the second bending mechanism 8, so that the glass 6 is evenly stressed between the two, effectively eliminating angle deviation and curved surface distortion. This structure is particularly suitable for arc transition bending of glass.

[0034] The deformation and bending mechanism 3 includes a flexible deformation section 10. The flexible deformation section 10 includes a number of connecting members 9 that are sequentially movably connected. Each connecting member 9 forms a chain-like structure of the flexible deformation section 10 through hinge or flexible connection. One end of the flexible deformation section 10 is in transmission connection with the first driving mechanism 5, and the first driving mechanism 5 drives the flexible deformation section 10 to run along the direction of bending the glass 6 when the glass 6 is bent.

[0035] The flexible deformation section 10 adopts a chain-like structure with hinge or flexible connection. Through the coordinated deformation of multiple connecting members 9, precise control of the bending curvature of the glass 6 is achieved. When the first driving mechanism 5 drives the flexible deformation section 10 to run, each connecting member 9 can adapt to the local deformation of the glass 6 to avoid stress concentration.

[0036] Above or below the deformation and bending mechanism 3, there is a second bending mechanism 8. The second bending mechanism 8 includes a bending die 2 corresponding to the flexible deformation section 10. The bending die 2 is provided with a die arc surface 11 for cooperating with the bending of the glass 6.

[0037] By arranging the bending die 2 of the second bending mechanism 8 corresponding to the flexible deformation section 10 up and down, the die arc surface 11 provides a reference forming surface for the glass 6, while the flexible deformation section 10 dynamically fills the bending gap to ensure uniform stress. This structure combines the positioning advantages of a rigid die and the deformation ability of a flexible mechanism.

[0038] The deformation and bending mechanism 3 further includes a first bending cooperation section 12 connected to the flexible deformation section 10. The second bending mechanism 8 includes a second bending cooperation section 13 and a third bending cooperation section 14 respectively located at both ends of the bending die 2. The bending die 2 is located between the second bending cooperation section 13 and the third bending cooperation section 14; The first bending cooperation section 12 and the second bending cooperation section 13 are arranged horizontally and transversely, and the first bending cooperation section 12 and the second bending cooperation section 13 are arranged vertically corresponding to each other; the third bending cooperation section 14 is arranged vertically and cooperates with the flexible deformation section 10 to bend the glass 6 together.

[0039] The sectional design of the first bending cooperation section 12, the second bending cooperation section 13 and the third bending cooperation section 14 optimizes the conveying and bending process of the glass 6. The horizontally and transversely arranged cooperation sections ensure the precise positioning of the glass 6 to the bending station, while the vertically arranged third bending cooperation section 14 and the flexible deformation section 10 jointly complete the bending action. The vertically corresponding layout reduces the displacement deviation of the glass 6 and has a compact structure, saving the equipment occupation space.
