Description

Technical Field

[0001] This utility model belongs to the field of ultra-thin flexible glass production technology, and more specifically, it relates to an ultra-thin flexible glass bonding device. Background Technology

[0002] As the advantages of ultra-thin flexible glass covers become increasingly apparent in the foldable screen phone industry, customer demand for these products is gradually increasing. Simultaneously, the ultra-thin flexible glass lamination process has matured and is undergoing mass production. However, mass production has brought a series of problems due to the flexibility and thinness of ultra-thin glass, including numerous film-tearing issues during lamination and low visual alignment accuracy, resulting in a reduction in the effective area of ​​the product and a loss in yield. In existing production processes, the film-tearing problem before lamination of ultra-thin glass causes issues such as bubbles and indentations after lamination. Rolling cannot completely remove these issues, making this method inefficient, and the bubbles from lamination can cause defects in subsequent production processes. The disadvantages of existing technologies are: ① Current products are thin (10-70μm), flexible, and fragile. Whether placed manually or by a robotic arm, the product will have wrinkles and unevenness, leading to bubbles and misalignment during lamination; ② Current lamination uses robotic arms for film tearing, but the robotic arm's tearing path is limited, sometimes resulting in the entire product being discarded, leading to inaccurate product placement, which is also a significant factor affecting yield.

[0003] Existing technology includes a patent titled "Glass Bonding Apparatus" with publication number CN103568443B. This patent discloses a glass bonding apparatus comprising a drying device, a support platform, and a pressing carrier. The drying device is used to dry an ultra-thin plain glass and a glass substrate; the support platform can hold the dried ultra-thin plain glass and the glass substrate; and the pressing carrier presses the ultra-thin plain glass onto the glass substrate along a fixed direction. The advantage of this invention is that it provides a glass bonding apparatus that can effectively bond flexible glass to a glass substrate without the need for a solution. This technology does not relate to the technical problems or solutions of this application. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an ultra-thin flexible glass bonding device that, in view of the shortcomings of the prior art, provides a device with a simple structure that can reliably achieve film peeling and bonding after the ultra-thin flexible glass to be bonded is placed on a vacuum platform, and can effectively detect the placement position of the ultra-thin flexible glass on the vacuum platform, adjust the position of inaccurately placed ultra-thin flexible glass, and improve the bonding accuracy and bonding efficiency of ultra-thin flexible glass.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model is an ultra-thin flexible glass bonding device, including a rotating component and a detection component. A vacuum platform is set on the upper part of the rotating component. The vacuum platform includes a weak vacuum hole group and a strong vacuum hole group. The detection component includes a component support and a detection optical fiber, and the detection optical fiber is aligned with the upper surface of the vacuum platform.

[0007] The rotating component includes a motor, which is connected to the device base via a connecting shaft.

[0008] The weak vacuum hole group includes multiple weak vacuum holes, and the strong vacuum hole group includes multiple strong vacuum holes.

[0009] The vacuum platform is equipped with a weak vacuum chamber, which is connected to a group of weak vacuum holes. The weak vacuum chamber is connected to a first vacuum pump through a pipeline.

[0010] The vacuum platform is equipped with a strong vacuum chamber, which is connected to a strong vacuum hole group. The strong vacuum chamber is connected to a second vacuum pump through a pipeline.

[0011] The weak vacuum hole group and the strong vacuum hole group are arranged on the upper surface of the vacuum platform.

[0012] The detection components include a side detection component and a front detection component. The side detection component is located on the side of the vacuum platform, and the front detection component is located at the front of the vacuum platform.

[0013] The side detection component and the front detection component are respectively equipped with component brackets and detection optical fibers.

[0014] The detection fiber beam of the side detection component is perpendicular to the side of the vacuum platform, and the detection fiber beam of the front detection component is perpendicular to the front of the vacuum platform.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] The ultra-thin flexible glass bonding device of this invention is structurally designed with a rotating component and a detection component. A vacuum platform is mounted on top of the rotating component, which is connected to the vacuum platform. Rotation of the rotating component allows the vacuum platform to rotate. The detection component is positioned close to the rotating component to detect whether the glass placed on the vacuum platform is accurately positioned. The vacuum platform includes a weak vacuum hole group and a strong vacuum hole group. The weak vacuum hole group provides a weak vacuum for adsorbing the glass, while the strong vacuum hole group provides a strong vacuum for adsorbing the glass. After the robotic arm places the glass on the vacuum platform, the glass placement is first detected. If the detection is successful, the film peeling process proceeds; if it fails, a correction process is performed before the film peeling process. During glass position detection, the detection component is activated. The component bracket of the detection component is used to mount a detection optical fiber, which is aligned with the upper surface of the vacuum platform. The detection optical fiber emits a detection beam, which acts on the side of the glass. If the emitted beam is not obstructed by the side of the glass, it indicates that the glass is correctly positioned and has passed the placement test. If the emitted light beam is obstructed by the side of the glass, it indicates that the glass is misaligned and its condition is unacceptable. At this point, the rotating component is controlled to rotate a certain angle until the emitted light beam is no longer obstructed by the side of the glass, indicating that the correction is complete. During the subsequent glass film removal process, the strong vacuum aperture group first provides a strong vacuum suction force. This strong vacuum enhances the adhesion of the glass product on the vacuum platform, effectively counteracting the force applied by the robotic arm during the film removal process and preventing product displacement, thus ensuring the glass position is not affected. Once the robotic arm senses the completion of the film removal process, the vacuum switches to a weak vacuum aperture group, providing a weak vacuum suction force to meet the robotic arm's subsequent adhesion requirements for the glass.

[0024] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0025] As attached Figure 1 -Appendix Figure 5As shown, this utility model is an ultra-thin flexible glass bonding device, including a rotating component 1 and a detection component 2. A vacuum platform 3 is arranged on the upper part of the rotating component 1. The vacuum platform 3 includes a weak vacuum hole group 4 and a strong vacuum hole group 5. The detection component 2 includes a component support 6 and a detection optical fiber 7, which is aligned with the upper surface of the vacuum platform 3. The above structure addresses the shortcomings of the prior art by proposing an improved technical solution. In the structural configuration, the rotating component 1 and the detection component 2 are fabricated separately. The vacuum platform 3 is arranged on the upper part of the rotating component 1, and the rotating component 1 is connected to the vacuum platform 3. The rotation of the rotating component 1 enables the rotation of the vacuum platform 3. The detection component 2 is positioned close to the rotating component 1 and is used to detect whether the glass placed on the vacuum platform 3 is accurately positioned. The vacuum platform 3 includes a weak vacuum hole group 4 and a strong vacuum hole group 5. The weak vacuum hole group 4 provides a weak vacuum for adsorbing the glass 11, and the strong vacuum hole group 5 provides a strong vacuum for adsorbing the glass 11. After the robotic arm places glass 11 onto the vacuum platform 3, the placement position of glass 11 is first checked. If the check is successful, the film peeling process proceeds; if it fails, a correction process is performed before the film peeling process. During the glass 11 position check, the detection component 2 is activated. The component bracket 6 of the detection component 2 is used to install the detection optical fiber 7. The detection optical fiber 7 is aligned with the upper surface of the vacuum platform 3 and is used to emit a detection beam 12. The beam 12 acts on the side of glass 11. If the emitted beam 12 is not obstructed by the side of glass 11, it indicates that the glass 11 is correctly positioned and placed successfully. If the emitted beam 12 is obstructed by the side of glass 11, it indicates that the glass 11 is not positioned correctly and is not in good condition. At this time, the rotating component 1 is controlled to rotate a certain angle until the emitted beam 12 is not obstructed by the side of glass 11, indicating that the correction is complete. During the subsequent glass peeling process, the strong vacuum orifice group 5 is first controlled to provide a strong vacuum adsorption force. This strong vacuum enhances the adsorption force on the glass 11 product on the vacuum platform 3, effectively counteracting the force applied by the robotic arm during the peeling process and preventing product displacement, thus ensuring the position of the glass 11 is not affected. After the robotic arm senses the completion of the glass peeling process, the vacuum switches to a weak vacuum adsorption force provided by the weak vacuum orifice group 4. This weak vacuum meets the robotic arm's adsorption requirements for subsequent bonding of the glass 11. The ultra-thin flexible glass bonding device described in this invention has a simple structure. After the ultra-thin flexible glass to be bonded is placed on the vacuum platform, it can reliably achieve peeling adsorption and bonding adsorption. Simultaneously, it effectively detects the placement position of the ultra-thin flexible glass on the vacuum platform, adjusting the position of inaccurately placed ultra-thin flexible glass, thereby improving the bonding accuracy and efficiency of the ultra-thin flexible glass.

[0026] The rotating component 1 includes a motor, which is connected to the device base 8 via a connecting shaft. In this structure, the motor is fixed below the rotating component, and the vacuum platform is fixed above the rotating component. By controlling the rotation of the motor, the motor drives the rotating component to rotate, which in turn drives the vacuum platform to rotate synchronously.

[0027] The weak vacuum hole group 4 includes multiple weak vacuum holes, and the strong vacuum hole group 5 includes multiple strong vacuum holes. In this structure, the force of the weak vacuum is less than that of the strong vacuum. The strong vacuum provides greater adsorption force when peeling the film, while the weak vacuum provides less adsorption force when bonding.

[0028] The vacuum platform 3 has a weak vacuum chamber inside, which is connected to a weak vacuum port group 4. The weak vacuum chamber is connected to a first vacuum pump via a pipeline. The vacuum platform 3 also has a strong vacuum chamber inside, which is connected to a strong vacuum port group 5. The strong vacuum chamber is connected to a second vacuum pump via a pipeline. In this structure, each vacuum pump provides a corresponding vacuum force to meet the usage requirements.

[0029] The weak vacuum pore group 4 and the strong vacuum pore group 5 are disposed on the upper surface of the vacuum platform 3. With the above structure, the glass 11 can be reliably adsorbed when placed on the upper surface of the vacuum platform 3.

[0030] The detection component 2 includes a side detection component 9 and a front detection component 10. The side detection component 9 is disposed on the side of the vacuum platform 3, and the front detection component 10 is disposed at the front of the vacuum platform 3. Because the glass has a square structure, two detection components 2 are required: the side detection component 9 emits a light beam from the side, and the front detection component 10 emits a light beam from the front, thus enabling more accurate detection of the glass position from two directions.

[0031] The side detection component 9 and the front detection component 10 are respectively equipped with a component support 6 and a detection optical fiber 7. In the above structure, the component support is fixedly connected, and the detection optical fiber is fixed on the component support. The beam 12 of the detection optical fiber 7 of the side detection component 9 is perpendicular to the side of the vacuum platform 3 and is emitted horizontally. The beam 12 of the detection optical fiber 7 of the front detection component 10 is perpendicular to the front of the vacuum platform 3 and is emitted horizontally, reliably meeting the usage requirements.

[0032] The ultra-thin flexible glass bonding device of this utility model is structurally designed with a rotating component 1 and a detection component 2. A vacuum platform 3 is mounted on the upper part of the rotating component 1, and the rotating component 1 is connected to the vacuum platform 3. The rotation of the rotating component 1 enables the rotation of the vacuum platform 3. The detection component 2 is positioned close to the rotating component 1 and is used to detect whether the glass 11 placed on the vacuum platform 3 is accurately positioned. The vacuum platform 3 includes a weak vacuum hole group 4 and a strong vacuum hole group 5. The weak vacuum hole group 4 provides a weak vacuum adsorption force for adsorbing the glass 11, and the strong vacuum hole group 5 provides a strong vacuum adsorption force for adsorbing the glass 11. After the robotic arm places the glass 11 onto the vacuum platform 3, the placement position of the glass 11 is first detected. If the detection is qualified, the film peeling process is performed; if the detection is unqualified, a correction process is performed before the film peeling process. During the glass 11 position detection, detection component 2 is activated. The component bracket 6 of detection component 2 is used to mount the detection fiber optic cable 7. The detection fiber optic cable 7 is aligned with the upper surface of the vacuum platform 3 and emits a detection beam 12. The beam 12 acts on the side of glass 11. If the emitted beam 12 is not obstructed by the side of glass 11, it indicates that glass 11 is correctly positioned and placed correctly. If the emitted beam 12 is obstructed by the side of glass 11, it indicates that glass 11 is not positioned correctly and is not in a qualified state. At this time, the rotating component 1 is controlled to rotate a certain angle until the emitted beam 12 is not obstructed by the side of glass 11, indicating that the correction is complete. Then, during the glass film removal process, the strong vacuum hole group 5 is first controlled to provide a strong vacuum adsorption force. The strong vacuum strengthens the adsorption force on the glass 11 product on the vacuum platform 3 to effectively cope with the force applied by the robotic arm during the subsequent film removal process, preventing the product from shifting during the film removal process and ensuring that the position of glass 11 is not affected. After the robotic arm senses the completion of the glass peeling process, the vacuum is transformed into a weak vacuum adsorption force provided by the weak vacuum hole group 4. The weak vacuum meets the adsorption requirements of the robotic arm for subsequent bonding of the glass 11.
