Description

Technical Field

[0001] This invention relates to the field of positioning and adjustment devices, and more specifically to a rapid and precise positioning and adjustment device for peeling substrate glass. Background Technology

[0002] Large-size substrate semi-finished glass is a core material in display panel manufacturing. It typically refers to glass substrates used in high-generation lines, with sizes reaching 2.5 meters × 2.2 meters or more, and thicknesses generally controlled at 0.5 millimeters or less. As the "skeleton" of LCD and OLED panels, its cost accounts for 20% of the panel's raw materials, directly determining key performance characteristics such as light transmittance, thickness, weight, and viewing angle.

[0003] Semi-finished substrate glass can be divided into large-size substrate glass and small-size substrate glass according to size. Large-size substrate glass is also known as high-generation substrate glass, and depending on the generation, it can be further divided into 4.5, 6, 8, 8.5, 8.6, 8.7, 10, 10.5, and 11 generations. To improve the compatibility of the production line, high-generation glass processing lines typically handle two or more substrate glass types with similar sizes. Therefore, surface grinding and peeling machines are used in scenarios where it is necessary to peel substrate glass of different sizes.

[0004] Traditional positioning adjustment devices for surface grinding and peeling machines rely on motor lead screws for adjustment. However, these devices become problematic over time. Given the complex operation of surface grinding and peeling machines, which require large amounts of water, and the limitations of the machine's mechanical structure, rust and jamming are extremely difficult to maintain and clean. This rusting can cause the device to jam, resulting in poor operation and adjustment accuracy. Consequently, when the machine peels the surface-ground glass from the tray, there is a risk of glass breakage. Furthermore, existing positioning adjustment devices are overly complex, costly, and difficult to maintain. Summary of the Invention

[0005] The purpose of this invention is to provide a rapid and precise positioning and adjustment device for peeling off substrate glass, thereby solving the following technical problems: How to improve the accuracy of the positioning adjustment device when a glass stripper is stripping substrates of different sizes, and how to improve the ease of use of the positioning adjustment device while reducing the risk of glass substrate breakage.

[0006] The objective of this invention can be achieved through the following technical solutions: A fast and precise positioning and adjustment device for peeling substrate glass includes a top frame, an X-axis moving mechanism mounted on the lower side of the top frame, a Y-axis moving mechanism connected to the moving end of the X-axis moving mechanism, and a suction cup gripping mechanism connected to the moving end of the Y-axis moving mechanism for gripping the substrate glass. The X-axis moving mechanism is used to drive the Y-axis moving mechanism to move in the X-axis direction, and the Y-axis moving mechanism is used to drive the suction cup gripping mechanism to move in the Y-axis direction; the X-axis direction and the Y-axis direction are perpendicular to each other.

[0007] In a further embodiment of the present invention: the X-axis moving mechanism includes multiple sets of X-axis linear drive mechanisms installed on the lower side of the top frame and arranged in a row and column manner, and the moving ends of the multiple sets of X-axis linear drive mechanisms are connected to the same X-axis frame.

[0008] In a further embodiment of the present invention: the Y-axis moving mechanism includes multiple sets of Y-axis linear drive mechanisms installed on the lower side of the X-axis frame and arranged in a row and column manner, and the moving ends of the multiple sets of Y-axis linear drive mechanisms are connected to the same Y-axis frame.

[0009] In a further embodiment of the present invention: the suction cup gripping mechanism is mounted on the lower side of the Y-axis frame.

[0010] In a further embodiment of the present invention: the X-axis linear drive mechanism includes a mounting plate, one side of which is fixedly connected to the lower side of the top frame, and mounting seats are respectively installed at both ends of the other side. A linear bearing guide rod is connected between the two mounting seats, and two linear bearings are installed on the linear bearing guide rod. It also includes a limiting mechanism to limit the movement of the two linear bearings respectively; It also includes a connecting plate, one side of which is fixedly connected to the two linear bearings, and the other side is fixedly connected to the X-axis frame.

[0011] In a further embodiment of the present invention: the limiting mechanism is provided in two sets, which are used to limit the two linear bearings respectively; each set of limiting mechanism includes a fixing ring installed on the guide rod of the linear bearing and a limiting adjusting rod installed on the inner side of the mounting base, wherein the limiting adjusting rod and the fixing ring are respectively located on both sides of the corresponding linear bearing.

[0012] In a further embodiment of the present invention, the extension length of the limiting adjustment rod inside the mounting base is adjustable.

[0013] In a further embodiment of the present invention: the limiting adjustment rod is a bolt threaded onto the mounting base.

[0014] In a further embodiment of the present invention, the Y-axis linear drive mechanism has the same structure as the X-axis linear drive mechanism.

[0015] In a further embodiment of the present invention: the positioning adjustment device is used for position adjustment of the peeling machine when peeling off the 8.5 generation substrate glass and the 8.6 generation substrate glass.

[0016] The beneficial effects of this invention are: (1) The positioning adjustment device of the present invention drives the X-axis frame to move in the X direction through the X-axis linear drive mechanism, and then drives the Y-axis linear drive mechanism to move at a fixed distance in the X-axis direction. Similarly, the Y-axis linear drive mechanism in the Y-axis moving mechanism can drive the suction cup mechanism to move at a fixed distance in the Y-axis direction, thereby realizing the separate / common movement of the suction cup mechanism in the X-axis direction and the Y-axis direction, thereby realizing the position adjustment of the suction cup mechanism and making it suitable for substrate glass of different sizes.

[0017] (2) The X-axis linear drive mechanism and the Y-axis linear drive mechanism in the positioning adjustment device of the present invention achieve linear movement through the cooperation between the linear bearing and the linear bearing guide rod. The linear bearing guide rod and the linear bearing are in smooth contact. Compared with the screw cooperation method in the prior art, the smooth contact cooperation is more stable and less prone to jamming due to rust. Therefore, it is beneficial to the safe transport of the glass substrate.

[0018] (3) The positioning adjustment device of the present invention has a stable structure, and can achieve rapid positioning and precise adjustment in the X-axis and Y-axis directions, and is easy to maintain; it can prevent the adjustment device mechanism from rusting and aging in complex scenarios with a large amount of water, resulting in poor adjustment accuracy of the mechanism and thus causing glass breakage during the peeling process, thereby reducing the risk of glass breakage when the glass peeling machine peels off the glass.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0024] In the description of this invention, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0025] Please see Figure 1 This embodiment discloses a rapid and precise positioning and adjustment device for peeling substrate glass, which is installed on the peeling machine of a glass processing production line. This device enables rapid positioning and precise adjustment of the peeling machine's adjustment device for substrate glass of different sizes, facilitating the peeling machine's removal of the surface-ground glass from the tray and its transport to the peeling machine's discharge line. The precision of the rapid positioning and adjustment device varies depending on the size of the substrate glass being peeled. Taking 8.5-generation and 8.6-generation substrate glass as examples: 8.5-generation substrate glass is 2200mm (±0.1mm) x 2500mm (±0.1mm), and 8.6-generation substrate glass is 2250mm (±0.1mm) x 2600mm (±0.1mm).

[0026] Please see Figure 2-3The rapid and precise positioning and adjustment device for peeling substrate glass in this embodiment includes a top frame 1, an X-axis moving mechanism mounted on the lower side of the top frame 1, a Y-axis moving mechanism connected to the moving end of the X-axis moving mechanism, and a suction cup gripping mechanism 6 connected to the moving end of the Y-axis moving mechanism for gripping the substrate glass; wherein, the X-axis moving mechanism is used to drive the Y-axis moving mechanism to move in the X-axis direction, the Y-axis moving mechanism is used to drive the suction cup gripping mechanism 6 to move in the Y-axis direction, and the X-axis direction and the Y-axis direction are perpendicular to each other.

[0027] Specifically, please refer to Figure 4 The X-axis moving mechanism includes multiple sets of X-axis linear drive mechanisms 2 installed on the lower side of the top frame 1 and arranged in a row and column manner. The moving ends of the multiple sets of X-axis linear drive mechanisms 2 are connected to the same X-axis frame 3. The Y-axis moving mechanism includes multiple sets of Y-axis linear drive mechanisms 4 installed on the lower side of the X-axis frame 3 and arranged in a row and column manner. The moving ends of the multiple sets of Y-axis linear drive mechanisms are connected to the same Y-axis frame 5. The suction cup gripping mechanism 6 is installed on the lower side of the Y-axis frame 5.

[0028] It should be noted that the specific number of X-axis linear drive mechanism 2 and Y-axis linear drive mechanism 4 is not limited and can be determined according to actual needs. It is only necessary to meet the requirement of uniform distribution in rows and columns to ensure the overall force balance of the device. For example, in this embodiment, a total of 6 sets of X-axis linear drive mechanism 2 are arranged in 2 rows and 3 columns, and a total of 8 sets of Y-axis linear drive mechanism 4 are arranged in 4 rows and 2 columns.

[0029] The positioning adjustment device has a simple structure and is easy to maintain.

[0030] The X-axis linear drive mechanism 2 and the Y-axis linear drive mechanism 4 have the same specific structure. The only difference is the driving direction. That is, the X-axis linear drive mechanism 2 is used for driving in the x-direction, and the Y-axis linear drive mechanism 4 is used for driving in the Y-axis direction.

[0031] Please see Figure 5 Taking the X-axis linear drive mechanism 2 as an example, the X-axis linear drive mechanism 2 includes a mounting plate 201. One side of the mounting plate 201 is fixedly connected to the lower side of the top frame 1, and the two ends of the other side are respectively mounted with mounting seats 202. A linear bearing guide rod 203 is connected between the two mounting seats 202, and two linear bearings 204 are mounted on the linear bearing guide rod 203. It also includes two sets of limiting mechanisms, which are used to limit the two linear bearings 204 respectively. It also includes a connecting plate 207. One side of the connecting plate 207 is fixedly connected to the two linear bearings 204, and the other side is fixedly connected to the X-axis frame 3.

[0032] Linear movement can be achieved through the cooperation between linear bearing 204 and linear bearing guide rod 203. The linear bearing guide rod 203 and linear bearing 204 have a smooth contact cooperation. Compared with the screw cooperation method in the prior art, the smooth contact cooperation is more stable and less prone to jamming due to rust. Therefore, it is beneficial to the safe transport of glass substrate.

[0033] It should be noted that the structure of the limiting mechanism is not specifically limited, as long as it meets the requirement of positioning the linear bearing 204. For example, in this embodiment, there are two sets of limiting mechanisms. Each set of limiting mechanisms includes a fixing ring 205 installed on the linear bearing guide rod 203 and a limiting adjustment rod 206 installed inside the mounting base 202. The limiting adjustment rod 206 and the fixing ring are located on both sides of the corresponding linear bearing 204, thereby limiting the two linear bearings 204 respectively.

[0034] The extension length of the limit adjustment rod 206 inside the mounting base 202 is adjustable with an accuracy within ±0.1mm. Specifically, in this embodiment, the limit adjustment rod 206 is a bolt threaded onto the mounting base 202, thereby controlling the limit distance.

[0035] In detail, when adjusting the displacement in the X-axis direction using the X-axis linear drive mechanism 2, it is only necessary to loosen the retaining ring 205, allowing the linear bearing 204 to move linearly on the linear bearing guide rod 203. When the two linear bearings 204 move to the limit adjustment rod 206 respectively, they stop moving. Then, the retaining ring 205 is moved to the side of the corresponding linear bearing 204 and locked, thereby fixing the linear bearing 204 between the retaining ring 205 and the limit adjustment rod 206, realizing the fixed distance movement of the linear bearing 204, thereby sequentially driving the connecting plate 207 and the X-axis frame 3 to adjust their positions in the X-axis direction.

[0036] Working principle of the invention: When using the positioning adjustment device of this embodiment, the X-axis linear drive mechanism 2 drives the X-axis frame 3 to move in the X direction, thereby driving the Y-axis linear drive mechanism 4 to move at a fixed distance in the X-axis direction. Similarly, the Y-axis linear drive mechanism 4 in the Y-axis moving mechanism can drive the suction cup mechanism to move at a fixed distance in the Y-axis direction, thereby realizing the separate / joint movement of the suction cup mechanism in the X-axis direction and the Y-axis direction, thereby realizing the position adjustment of the suction cup mechanism and making it suitable for substrate glass of different sizes.

[0037] In the description of this invention, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or specific orientational structure and operation. Therefore, they should not be construed as limitations on the invention. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "multiple" means two or more.

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
