Description

Technical Field

[0001] This utility model relates to the field of substrate glass production technology, and in particular to a substrate glass support mechanism. Background Technology

[0002] In the LCD glass substrate production process, semi-finished product processing is a crucial step, situated between forming and grinding. The main tasks of this step are to convey, weigh, longitudinally cut, pack, sort, and feed the formed, pulled-down glass sheets to the grinding area. Glass substrates of normal quality are directly fed into the grinding area, while those exceeding the grinding load are collected by a packing robot and allowed to remain in place until the grinding process can handle them. During this process, the glass is gripped by the transport fixture's jaws and transported in a pulling motion. In the packing area, the packing robot uses suction cups to pick up the glass sheets, flips them, and places them on an A-frame.

[0003] Existing technical problems: Current holding mechanisms still have some issues in practical applications. First, they cannot completely eliminate glass plate movement, especially during the process of the glass plate being gripped and pulled down by the transport fixture's jaws. This movement can lead to glass breakage or failure to establish vacuum pressure in the suction cups. Second, when in contact with the glass plate, existing holding mechanisms may cause scratches and glass dust, affecting not only the quality of the glass but also potentially polluting the production environment. Therefore, reducing glass plate movement and scratches is a pressing issue that needs to be addressed in the current technical field. Utility Model Content

[0004] To address the existing problems, this utility model provides a substrate glass holding mechanism, which aims to solve the problem that during the production process of glass substrates, the glass plates in the semi-finished product processing stage may still shake during transportation and packaging, resulting in abnormal situations such as glass plate breakage or failure to establish suction cup vacuum pressure. At the same time, the existing holding mechanism is also insufficient in preventing the glass plate from coming into contact with the equipment and causing scratches and glass dust. The glass plate may still come into contact with the equipment during transportation and packaging, resulting in scratches or glass dust.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A substrate glass support mechanism includes a frame body, a reinforcing top frame, an adjusting bottom frame, an upper connecting profile, a lower connecting profile, profile corner brackets, an L-shaped connecting plate, a cutting board strip mounting block, a cutting board strip, and a display board cylinder. The frame body is formed by fixing and connecting several longitudinally and laterally arranged main profiles. The upper and lower connecting profiles are both longitudinally arranged and shorter than the main profiles. The upper connecting profile is connected to the uppermost laterally arranged main profile of the frame body through profile corner brackets. The lower connecting profile is connected to the adjusting bottom frame through profile corner brackets. The cutting board strip mounting block is fixedly connected to one end of the connecting profile through an L-shaped connecting plate, and a cutting board strip is provided on the cutting board strip mounting block. The display board cylinder is fixedly connected to the frame body and the adjusting bottom frame respectively.

[0007] As a further improvement of this utility model, it also includes a pneumatic sliding table; the pneumatic sliding table includes at least two sliders, at least two guide rails, a supporting cylinder, a connecting base plate, and a connecting frame; the guide rails are arranged side by side on the connecting base plate, the guide rails are slidably connected to the sliders, the sliders are fixedly connected to the connecting frame, and the connecting frame is fixedly connected to the frame body; the supporting cylinder is provided on the connecting base plate; the connecting base plate is set on the substrate glass production line.

[0008] As a further improvement of this utility model, the connection between the support cylinder and the slider adopts a floating joint structure.

[0009] As a further improvement of this utility model, the display panel cylinder is located on the lower side of the frame body.

[0010] As a further improvement of this utility model, a protective cover is provided on the display panel cylinder.

[0011] As a further improvement of this utility model, the display panel cylinder is a dual-shaft cylinder.

[0012] As a further improvement of this utility model, the cutting board strip is made of highly elastic rubber material.

[0013] As a further improvement of this utility model, the main body profile is made of aluminum alloy material.

[0014] As a further improvement of this utility model, the distribution of the connecting profile is dense in the middle and sparse on both sides.

[0015] As a further improvement of this utility model, the distribution of the horizontally arranged main profile is denser at the bottom and sparser at the top.

[0016] This utility model has the following beneficial effects: The main frame is formed by the fixed connection of longitudinal and transverse main profiles, providing a stable framework for the entire support mechanism. The display plate cylinders connect the main frame and the adjusting base frame, allowing for fine-tuning of the frame's position and angle to accommodate glass substrates of different sizes, reducing the possibility of contact between the glass and equipment during transport and packaging. The connecting profiles, arranged longitudinally and shorter than the main profiles, connect to the uppermost transverse main profile or the adjusting base frame via angle brackets. This connection method ensures a strong connection, reducing scratches and glass dust, while also facilitating installation and disassembly. The anvil strip mounting block connects to the lower end of the connecting profile via an L-shaped connecting plate, providing a stable support position for the glass substrate.

[0017] Preferably, the pneumatic slide design allows the frame body to move forward and backward in conjunction with the suction cups on the production line; powered by a cylinder, the frame body moves smoothly through the sliding connection between the guide rail and the slider, allowing for flexible adjustment of the substrate glass's support position, thus improving production efficiency and automation; the connecting base plate is set on the substrate glass production line, providing a stable installation foundation for the entire pneumatic slide, enabling easy integration into existing production lines and reducing the difficulty and cost of modifying the production line.

[0018] Preferably, a floating joint structure is adopted between the cylinder and the slider, which can effectively compensate for the coaxiality error during the installation of the cylinder and the slider. In the actual installation process, it is difficult to guarantee the absolute coaxiality of the cylinder and the slider. The floating joint can allow a certain angular deviation, avoid stress concentration caused by installation errors, and reduce the wear and damage of components. This structure can reduce the vibration and noise of the mechanism during operation, make the movement of the frame body more stable, thereby improving the accuracy and stability of the substrate glass and ensuring product quality.

[0019] Preferably, the display plate cylinder located on the lower side of the frame body can provide auxiliary support and unfolding for the substrate glass. During the placement of the substrate glass, the display plate cylinder can provide additional support force to prevent the substrate glass from deforming or shifting due to its own weight or external forces, ensuring that the substrate glass remains flat and stable. By adjusting the stroke and pressure of the display plate cylinder, it can accommodate substrate glass of different sizes and thicknesses, improving the versatility and flexibility of the mechanism.

[0020] Preferably, the protective cover on the display plate cylinder can effectively prevent dust, impurities, liquids, etc. from the production environment from entering the cylinder. These contaminants may cause wear and corrosion of the internal parts of the cylinder, affecting the normal operation of the cylinder. The protective cover can extend the service life of the display plate cylinder, reduce maintenance costs and downtime. The protective cover can also prevent operators from accidentally coming into contact with the moving parts of the display plate cylinder during production, avoiding safety accidents and ensuring the personal safety of operators.

[0021] Preferably, the dual-axis cylinder has higher stability and load-bearing capacity. Compared with the single-axis cylinder, it can better withstand the weight of the substrate glass and the external force, ensuring the reliability of the display plate cylinder when supporting the substrate glass and reducing cylinder deformation and damage. The symmetrical structure of the dual-axis cylinder can make the cylinder run more smoothly, reducing shaking and vibration, thereby improving the positioning accuracy and stability of the substrate glass and helping to ensure product quality.

[0022] Preferably, the cutting board strip is made of highly elastic rubber material, which has good elasticity and cushioning properties. When the substrate glass rests on the cutting board strip, the highly elastic rubber material can absorb the impact force between the substrate glass and the cutting board strip, preventing the substrate glass from being damaged by collision and playing a role in protecting the substrate glass; the surface of the rubber material has a certain friction, which can prevent the substrate glass from sliding during the resting process, ensuring the stable resting of the substrate glass and improving the reliability of the production process.

[0023] Preferably, the main body profile is made of aluminum alloy. Aluminum alloy is lightweight, which significantly reduces the weight of the main frame compared to other metal materials, facilitating the installation, movement, and transportation of the mechanism. Aluminum alloy has high strength, which meets the requirements of the main frame to support the base glass, ensuring the stability and reliability of the mechanism. Aluminum alloy has good corrosion resistance, which allows it to be used for a long time in the production environment without easily rusting or corroding, extending the service life of the mechanism and reducing maintenance costs.

[0024] Preferably, the connecting profiles are distributed with a denser distribution in the middle and a sparser distribution at the edges. This layout is optimized based on the stress characteristics and center of gravity distribution of the substrate glass. During the support process, the middle part of the substrate glass experiences relatively greater stress, and the dense connecting profiles can provide stronger support, ensuring the strength and stability of the structure. The forces on the edges are smaller, and appropriately reducing the number of connecting profiles can save materials and reduce costs. A reasonable distribution of connecting profiles can make the stress distribution of the frame body more uniform, reduce local stress concentration, and improve the overall performance and reliability of the structure.

[0025] Optionally, the main profiles are arranged horizontally with a denser distribution at the bottom and a sparser distribution at the top, which conforms to the stress situation of the substrate glass when it is supported. The lower part of the substrate glass is subjected to greater stress, and the dense main profiles can enhance the load-bearing capacity of the lower structure and ensure the stability of the main frame. The upper part is subjected to relatively less stress, and reducing the number of main profiles can reduce the weight of the upper part, lower the center of gravity of the entire mechanism, and further improve the stability and safety of the mechanism. Under the premise of ensuring structural strength and stability, reasonably reducing the number of upper main profiles can save material costs and improve the economy of the mechanism.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0029] Unless otherwise defined below, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] Example 1 like Figure 1 As shown, the frame includes a main body, a reinforced top frame 15, an adjustable bottom frame 16, an upper connecting profile 17, a lower connecting profile 4, a first profile corner bracket 12, a second profile corner bracket 13, an L-shaped connecting plate 3, a cutting board strip mounting block 2, a cutting board strip 1, a first display board cylinder 5, and a second display board cylinder 6; the main body of the frame is formed by several longitudinally arranged main profiles 8 and transversely arranged main profiles 7 fixedly connected together.

[0031] Both the upper connecting profile 17 and the lower connecting profile 4 are arranged longitudinally and are shorter than the main profile. The lower side of the upper connecting profile 17 is connected to the uppermost horizontally arranged main profile 7 of the frame body through profile corner brackets. The upper side of the upper connecting profile 17 is connected to the horizontally arranged reinforcing top frame 15 through corner brackets. The position of the reinforcing top frame 15 is slightly higher than the uppermost horizontally arranged main profile 7 of the frame body.

[0032] The lower connecting profile 4 is connected to the adjusting base frame 16 via profile corner brackets. Specifically, the lower connecting profile 4 is connected to the adjusting base frame 16 from top to bottom via the second profile corner bracket 13 and the first profile corner bracket 12.

[0033] The load end and piston rod end of the display panel cylinder are fixedly connected to the frame body and the adjusting base frame 16, respectively, to adjust the horizontal distance between the frame body and the adjusting base frame 16.

[0034] The first display panel cylinder 5 and the second display panel cylinder 6 are fixedly connected to the frame body and the adjusting bottom frame 16 respectively, and the first display panel cylinder 5 and the second display panel cylinder 6 are symmetrically distributed on both sides of the frame body.

[0035] The cutting board strip mounting block 2 is fixedly connected to one end of the connecting profile through an L-shaped connecting plate 3, and the cutting board strip 1 is provided on the cutting board strip mounting block 2.

[0036] like Figure 2 As shown, this embodiment also includes a pneumatic sliding table; the pneumatic sliding table includes at least two sliders 11, at least two guide rails 10, a supporting cylinder 14, a connecting base plate 9, and a connecting frame 18; as shown Figure 2As shown in the front view (a) and left view (b), guide rails 10 are arranged side by side on the connecting base plate 9. The guide rails 10 are slidably connected to the slider 11. The slider 11 is fixedly connected to the connecting box frame 18. The connecting box frame 18 is fixedly connected to the frame body. A support cylinder 14 is provided on the connecting base plate 9. The connecting base plate 9 is set on the substrate glass production line.

[0037] In this embodiment, the connection between the cylinder 14 and the slider 11 adopts a floating joint structure. The floating joint of the cylinder is a connection device used to compensate for installation errors and absorb vibrations. Its typical structure consists of a ball joint and an axial sliding unit. The ball joint part (ball head and ball socket fit) allows the joint to deflect within ±5° to accommodate the angular deviation between the cylinder and the load; the axial sliding part (such as a splined shaft or linear bearing) provides 1-3mm radial displacement compensation to ensure that the piston rod is not affected by lateral forces. The two ends of the joint are connected by threads or flanges and are fixed to the piston rod end of the cylinder and the load end, respectively. The load end is fixedly connected to the slider 11, and the slider 11 is linked with the connecting frame 18 to drive the frame body to move forward and backward in conjunction with the suction cup adsorption operation on the production line.

[0038] The display panel cylinder is a dual-shaft cylinder.

[0039] The cutting board strip 1 is made of highly elastic rubber material.

[0040] The main profile is made of aluminum alloy.

[0041] The connecting profiles are distributed with a denser center and sparser edges. This layout is optimized based on the stress characteristics and center of gravity distribution of the substrate glass. During the support process, the central part of the substrate glass experiences relatively greater stress, and the denser connecting profiles provide stronger support, ensuring the strength and stability of the structure. The forces on the sides are smaller, and appropriately reducing the number of connecting profiles can save materials and lower costs. A reasonable distribution of connecting profiles can make the stress distribution of the frame structure more uniform, reduce local stress concentration, and improve the overall performance and reliability of the structure.

[0042] The distribution of the horizontally arranged main profiles 7 is denser at the bottom and sparser at the top. This distribution conforms to the stress distribution of the substrate glass when it is supported. The lower part of the substrate glass experiences greater stress, and the denser main profiles can enhance the load-bearing capacity of the lower structure and ensure the stability of the main frame. The upper part experiences relatively less stress, and reducing the number of main profiles can reduce the weight of the upper part, lower the center of gravity of the entire mechanism, and further improve the stability and safety of the mechanism. Under the premise of ensuring structural strength and stability, reasonably reducing the number of upper main profiles can save material costs and improve the economy of the mechanism.

[0043] Example 2 The difference between this embodiment and Embodiment 1 is that: 1) The display panel cylinder is located on the lower side of the frame body.

[0044] 2) A protective cover is installed on the cylinder of the display panel.

[0045] The display panel cylinder is located on the lower side of the main frame, such as Figure 2 As shown, the spreader cylinder can provide auxiliary support and unfolding for the substrate glass. During the substrate glass placement process, the spreader cylinder can provide additional support force to prevent the substrate glass from deforming or shifting due to its own weight or external forces, ensuring that the substrate glass remains flat and stable. By adjusting the stroke and pressure of the spreader cylinder, it can accommodate substrate glass of different sizes and thicknesses, improving the versatility and flexibility of the mechanism.

[0046] Protective covers are installed on the cylinders of the display panels, such as Figure 2 As shown, this protective cover effectively prevents dust, impurities, and liquids from the production environment from entering the cylinder. This is especially important when the display plate cylinder is located below the main frame, as glass dust can fall in from above. These contaminants can cause wear and corrosion of internal cylinder parts, affecting normal operation. The protective cover extends the service life of the display plate cylinder, reducing maintenance costs and downtime. Furthermore, the cover prevents operators from accidentally contacting the moving parts of the display plate cylinder during production, avoiding accidents and ensuring operator safety.

[0047] Advantages of this utility model: 1. Set up a support area. Install a support mechanism on the face of the glass plate adsorption. The support area can reduce the shaking of the glass plate and prevent the glass plate from contacting the equipment, thus avoiding scratches and glass dust.

[0048] 2. Optimize the support mechanism: By optimizing the existing support mechanism, it can better prevent the glass plate from coming into contact with the equipment, thus avoiding scratches and glass dust, and reducing the shaking and scratches of the glass plate during transportation and packaging.

[0049] 3. A shock-absorbing anvil strip 1 is added at the contact point between the glass plate and the equipment to reduce the possibility of scratches and glass dust caused by contact between the glass plate and the equipment. The above embodiments are merely one of the implementation methods to achieve the technical solution of this utility model.
