Description

Technical Field

[0001] This invention relates to the field of conveyor platform technology, and in particular to a guide conveyor platform capable of detecting settlement. Background Technology

[0002] There are two types of air-bearing platforms: air-bearing linear platforms and air-bearing (rotary) turntables. The core principle of a floating platform is a precision displacement platform composed of air bearings and electronic control components. Based on the air bearing principle, the load-bearing plate floats on air-bearing guide rails or air-bearing bearings, achieving frictionless and vibration-free smooth movement.

[0003] The high straightness and flatness of the air-floating platform depend on the air-floating guide rails, which are made of materials such as aluminum alloy, marble, and silicon carbide ceramics. Current technological improvements have adjusted the high-pressure film pressure distribution, air source pressure, throttling valve, and equalizing groove depth to give the air film a reasonable stiffness range, resulting in excellent support performance and precision. This type of air-floating platform is particularly suitable for supporting display glass substrates, minimizing friction and contact, and effectively preventing scratches on the substrates during transport.

[0004] The current liquid crystal evaporation equipment can only produce substrates with sizes much smaller than those that the conveying equipment can handle. To complete the liquid crystal substrate preparation, it typically needs to be quartered or hexadecimated before proceeding to the next process. Blade wheel cutting is the mainstream method, and its working principle can be simplified to two main actions: blade wheel marking and dicing roller pressing. The cutting blade and dicing roller are usually positioned between two different air-float platforms, and the cutting blade performs the cutting at the interval between these two platforms. This requires large-format glass substrates to travel to a set size and remain between different air-float platforms for the cutting process. This process demands a high degree of levelness from the two air-float platforms, requiring regular maintenance and calibration by equipment personnel to ensure the accuracy of both sides.

[0005] Current air flotation platforms have a complete flat surface, which can stably support the liquid crystal substrate. However, long-term use, cutting, equipment use, and the use of pneumatic devices can all cause the air flotation platform to sink or become unstable.

[0006] Currently, these substrates vary in thickness but are all transported via the same air-float platform. Generally, thinner glass has a larger internal circuit structure, making it prone to jamming during transport between different air-float platforms. Furthermore, after prolonged use in the fabrication process, different air-float platforms experience aerodynamic changes and vibrations, inevitably leading to issues such as loose screws or floor settlement. Because the entire air-float platform is a flat plane, structural shifts and changes cannot be perfectly synchronized, resulting in height differences between different platforms.

[0007] If the front air-bearing platform is higher than the rear air-bearing platform, the glass substrate will experience a shift in its rear center of gravity and a drop during transport. It will also drop again when the glass substrate is completely detached from the front air-bearing platform. This will cause the glass substrate to collide with the rear air-bearing platform, which may result in scratches, but this is not very harmful. If the front air-bearing platform is lower than the rear air-bearing platform, the substrate is more likely to collide or jam during transport, and the risk of downtime increases sharply. This situation is more serious and will have an adverse effect on the cutting and transport of the glass substrate.

[0008] Based on this, the present invention designs a guide conveying platform capable of detecting settlement to solve the above problems. Summary of the Invention

[0009] The purpose of this invention is to provide a guide conveying platform capable of detecting settling. This platform utilizes a transitional sliding plate between two air-float platforms. This sliding plate has a certain angle of attack, allowing the substrate to be guided and buffered upon arrival. A rotating shaft is located beneath the sliding plate, enabling it to rotate along the shaft. If the rotation angle exceeds a set range, an angle sensor will trigger an alarm. This rotational mechanism effectively avoids and mitigates direct impacts by seamlessly connecting the substrate to the rear platform. The rear side of the sliding plate is inserted into the rear platform to match the shape of the air-float platform, ensuring a seamless transfer of the substrate to the rear platform and reducing the risk of jamming or collisions during substrate transfer between different platforms.

[0010] This invention is implemented as follows: a guided conveyor platform capable of detecting settlement, comprising:

[0011] Front-end platform, back-end platform, skateboard platform, rotary axis, and limit block;

[0012] Both the front-end platform and the back-end platform are horizontally deployed stable platforms. The front-end platform is set in front of the back-end platform, and the front-end platform and the back-end platform are not connected.

[0013] The front-end platform is a complete platform composed of multiple block platforms arranged at even intervals along the left and right direction. The multiple block platforms that make up the front-end platform are arranged in parallel to each other. The front-end platform has the same structure as the back-end platform.

[0014] The rotating shaft is a straight circular shaft, which is horizontally and stably mounted between the front platform and the rear platform in the left-right direction. An angle sensor is also installed between the rotating shaft and the sliding platform.

[0015] The skateboard platform is a flat plate structure with a flat top. The skateboard platform is rotatably mounted on a rotating shaft, which is located at the bottom of the skateboard platform.

[0016] The limiting block is a stable, block-shaped structure, and it is positioned at the gap between the front-end platform and the back-end platform.

[0017] The front end of the skateboard platform can be detachably mounted on the top of the limiting block, and when the skateboard platform is stationary, its front side is tilted downwards.

[0018] The rear end of the skateboard platform is rotatably and flush with the gap between the block platforms of the rear end platform;

[0019] The skateboard platform does not come into contact with either the front-end or back-end platform.

[0020] Furthermore, the height of the front end of the skateboard platform when it is mounted on top of the limiting block is lower than the height of the front end platform, and the height difference is 4-10mm.

[0021] Furthermore, the front side of the skateboard platform is a flat edge, and the rear side of the skateboard platform extends backward with multiple protrusions. The protrusions on the rear side of the skateboard platform are clamped in the gaps of the rear platform without contacting each other. The skateboard platform and the protrusions on the rear side form an E-shaped integral structure, and the protrusions and notches of the skateboard platform face the direction of the rear platform.

[0022] When the skateboard platform is in a horizontal position, the top of the skateboard platform and the top of the rear platform are on the same plane.

[0023] Furthermore, multiple weight-reducing holes are provided on the rear side of the skateboard platform, and the front side of the skateboard platform is heavier than the rear side;

[0024] The top edges of the front and rear sides of the skateboard platform are rounded.

[0025] Furthermore, both the front-end platform and the back-end platform are air flotation platforms.

[0026] The beneficial effects of the present invention are: 1. The present invention makes two air flotation platforms into multiple platforms spaced apart and arranged into an intermittent air flotation platform. This structure can be connected with the sliding platform, so that the rear side of the sliding platform can be inserted into the rear platform, thereby providing seamless support for the glass substrate, making the glass substrate more stable to be transported, and effectively avoiding impact and falling on the steps.

[0027] 2. The limit block on the top of the skateboard platform is set up to form a forward-leaning angle of attack, which can play a role in buffering the glass substrate. After being impacted by the glass substrate, it will not directly react to the force, but will buffer the impact force through the rotation of the skateboard platform itself, thus avoiding direct impact.

[0028] 3. This device can smoothly and seamlessly connect the glass substrate to the rear platform by rotating the sliding platform, without any step-down or drop. Instead, the height change is formed by the rotation of the sliding platform, so that the glass substrate can smoothly transition from the front platform to the rear platform, making the glass substrate transportation and cutting process smoother and more stable.

[0029] 4. Angle sensors are also installed on the rotating shaft and sliding platform of this device to monitor the rotation angle of the sliding platform in real time. When the height difference between the front and rear platforms increases and the rotation angle exceeds the set range, the angle sensor will provide information and the entire device will issue an alarm to notify personnel to carry out timely maintenance and adjustment.

[0039] Please see Figures 1 to 6 As shown, the present invention provides a technical solution: a guide conveyor platform capable of detecting settlement, comprising:

[0040] Front-end platform 1, back-end platform 11, skateboard platform 2, rotating axis 3, and limiting block 4;

[0041] Both the front-end platform 1 and the back-end platform 11 are horizontally mounted stable platforms. The front-end platform 1 is located in front of the back-end platform 11, and the front-end platform 1 and the back-end platform 11 are not connected.

[0042] The front-end platform 1 is a complete platform composed of multiple block platforms arranged at even intervals along the left and right direction. The multiple block platforms that make up the front-end platform 1 are arranged in parallel to each other. The front-end platform 1 and the back-end platform 11 have the same structure.

[0043] The rotating shaft 3 is a straight circular shaft. The rotating shaft 3 is horizontally and stably mounted between the front platform 1 and the rear platform 11 in the left and right direction. An angle sensor 31 is also provided between the rotating shaft 3 and the skateboard platform 2.

[0044] The skateboard platform 2 is a flat plate structure with a flat top. The skateboard platform 2 is rotatably mounted on a rotating shaft 3, which is located at the bottom of the skateboard platform 2.

[0045] The limiting block 4 is a stable block structure, and the limiting block 4 is set at the interval between the front end platform 1 and the rear end platform 11.

[0046] The front end of the skateboard platform 2 can be detachably placed on the top of the limiting block 4, and the front side of the skateboard platform 2 is tilted downward when it is stationary.

[0047] The rear end of the skateboard platform 2 is rotatably and flush with the gap between the block platform of the rear end platform 11;

[0048] The sliding platform 2 does not contact the front platform 1 or the rear platform 11. By adding a transitional sliding platform 2 between the two air-bearing platforms, the glass substrate can be guided and buffered when transported to the sliding platform 2. A rotating shaft 3 is set under the sliding platform 2, allowing the sliding platform 2 to rotate in the front-back direction along the rotating shaft 3. If the rotation angle exceeds the set range, the angle sensor 31 will issue an alarm. Moreover, the rotation method can connect the substrate in a rotating manner, effectively avoiding and mitigating direct impact. The rear side of the sliding platform 2 is inserted into the rear platform 11 to match the shape of the rear platform 11, so that the substrate can be seamlessly transported on the rear platform 11, reducing the risk of jamming and collision when the substrate is transported between different platforms.

[0049] Among them, the height of the front end of the skateboard platform 2 when it is mounted on the top of the limiting block 4 is lower than the height of the front end platform 1, and the height difference is 4-10mm. This makes it easier for the skateboard platform 2 to generate a downward angle of attack at the front end, so that it can more smoothly receive the glass substrate being transported.

[0050] The front side of the skateboard platform 2 is a flat edge, and the rear side of the skateboard platform 2 extends backward with multiple protrusions. The protrusions on the rear side of the skateboard platform 2 are clamped in the gaps of the rear platform 11 without contacting each other. The skateboard platform 2 and the protrusions on the rear side form an E-shaped integral structure, and the protrusions and notches of the skateboard platform 2 face the rear platform 11.

[0051] When the skateboard platform 2 is in a horizontal state, the top of the skateboard platform 2 and the top of the rear platform 11 are on the same plane, which can make the skateboard platform 2 and the rear platform 11 tightly connected as a whole. When the glass substrate is transported, the front and rear connections can be stable, so that there is no disconnection between the skateboard platform 2 and the rear platform 11.

[0052] Multiple weight-reducing holes 21 are also provided on the rear side of the skateboard platform 2, and the front side of the skateboard platform 2 is heavier than the rear side;

[0053] The top edges of the front and rear sides of the skateboard platform 2 are rounded, making the structure of the skateboard platform 2 heavier at the front and lighter at the rear. This allows the skateboard platform 2 to tilt forward normally when no force is applied, and this structure enables the skateboard platform 2 to automatically return to its original position under the action of gravity.

[0054] Both the front-end platform 1 and the back-end platform 11 are air-floating platforms. Multiple air holes are evenly opened on the top of both the front-end platform 1 and the back-end platform 11. This is a conventional structure of air-floating platforms. The holes are opened to support the glass substrate. The glass substrate can also be supported by other platforms. However, air-floating platforms are currently the best support platform for display glass substrates, so they are selected, but not as a limitation.

[0055] In a specific embodiment of the present invention:

[0056] This invention provides a guide conveying platform capable of detecting settlement. The technical problem encountered by this invention is: 1. Current air-floating platforms consist of two complete planes, providing more stable support and buoyancy, and using other power sources to transport glass substrates. This is a conventional structure. However, the base surface and other structures of this type of air-floating platform can cause settlement or shaking, leading to a height difference between the front and rear ends. This causes abnormalities during glass substrate transport; a higher front and lower rear result in the glass substrate falling, while a lower front and higher rear result in the glass substrate being impacted. 1. The platform stops, preventing normal transport; 2. Because the floating platform continuously carries the glass substrate by pressurized airflow, and the glass substrate is also cut on this platform, the airflow and cutting will also vibrate. Over time, bolts or other components of the structure may loosen, which will cause the air-floating platform to deviate in height or tilt, affecting transport; 3. Abnormalities at the front and rear ends of the floating platform are generally difficult to detect until a fault or damage occurs. This makes platform inspection difficult and requires frequent and long-term inspections of the floating platform for cutting and transporting glass substrates.

[0057] The technical problem solved by the present invention is that by setting up a simple sliding plate platform 2 to connect the floating platforms at the front and rear ends, it plays a buffering and transition role, avoiding the glass substrate being dropped or impacted, and can also continuously monitor the height difference between the front platform 1 and the rear platform 11.

[0058] The technical effects achieved are as follows: 1. By manufacturing two air-floating platforms into multiple platforms spaced apart and arranging them into an intermittent front-end platform 1 and rear-end platform 11, this structure can be used to cooperate and connect with the sliding platform 2, so that the rear side of the sliding platform 2 can be inserted and connected into the rear-end platform 11, thereby providing seamless support for the glass substrate, enabling the glass substrate to be transported more stably and effectively avoiding impacts and falls on steps.

[0059] 2. The sliding platform 2 is mounted on top of the limiting block 4, forming a forward-leaning angle of attack, which can buffer the glass substrate. After being impacted by the glass substrate, it will not directly react to the force, but will buffer the impact force through the rotation of the sliding platform 2 itself, thus avoiding direct impact.

[0060] 3. This device, through the rotation of the sliding platform 2, can smoothly and seamlessly connect the glass substrate on the front platform 1 to the rear platform 11 by rotating it on the rotating shaft 3, without any step-down state. Instead, the height change is formed by the rotation of the sliding platform 2, so that the glass substrate is smoothly transitioned from the front platform 1 to the rear platform 11, making the glass substrate conveying and cutting process smoother and more stable.

[0061] 4. Angle sensors 31 are also installed on the rotating shaft 3 and the sliding platform 2 of this device, which can monitor the rotation angle of the sliding platform 2 in real time. When the height difference between the front and rear platforms increases and the rotation angle exceeds the set range, the angle sensor 31 will provide information and the entire device will issue an alarm to notify personnel to carry out timely maintenance and adjustment.

[0062] The technical solution in this invention is to solve the above problems, and the overall idea is as follows:

[0063] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0064] In manufacturing this invention, a front-end platform 1, a rear-end platform 11, a sliding plate platform 2, a rotating shaft 3, and a limiting block 4 are used.

[0065] Both front-end platform 1 and back-end platform 11 are horizontally deployed stable platforms. Front-end platform 1 is set in front of back-end platform 11, and there is no connection between front-end platform 1 and back-end platform 11.

[0066] The front-end platform 1 is a complete platform composed of multiple block platforms arranged evenly spaced in a left-right direction. These block platforms are parallel to each other, and the front-end platform 1 has the same structure as the rear-end platform 11. Both the front-end platform 1 and the rear-end platform 11 are air-floating platforms, and multiple air holes are evenly distributed on their tops. This structure is conventional; however, the front-end platform 1 and the rear-end platform 11 of this device are separate block platforms. This arrangement allows them to avoid contact with the sliding platform 2 structure, reduces the risk of contact, and facilitates the installation of other devices, thus making the structure of the front-end platform 1 and the rear-end platform 11 intermittent.

[0067] The rotating shaft 3 is a straight circular shaft. The rotating shaft 3 is horizontally and stably mounted between the front platform 1 and the rear platform 11 in the left and right direction. An angle sensor 31 is also set between the rotating shaft 3 and the sliding plate platform 2. The axis of the rotating shaft 3 is perpendicular to the forward direction of the substrate. The sliding plate platform 2 rotates along the rotating shaft 3 to ensure that the guidance and rotation direction are in the same direction as the forward direction of the glass substrate, so that the flow is smoother.

[0068] The skateboard platform 2 is a flat plate structure with a flat top. The skateboard platform 2 is rotatably mounted on the rotating shaft 3, which is located at the bottom of the skateboard platform 2.

[0069] The limiting block 4 is a stable block structure, and the limiting block 4 is set at the interval between the front platform 1 and the rear platform 11. The limiting block 4 can be a complete support frame or two separate support frames, as long as it can provide convenient support without affecting other components.

[0070] The front end of the skateboard platform 2 can be detachably mounted on top of the limiting block 4. When the skateboard platform 2 is stationary, its front side is tilted downwards. The height of the front end of the skateboard platform 2 mounted on top of the limiting block 4 is lower than the height of the front platform 1, with a height difference of 4-10mm. This height difference is sufficient to prevent the glass substrate from being impacted by a drop. When the skateboard platform 2 is mounted on top of the limiting block 4, its height is lower than the height of the front platform 1, and a height difference h is formed between the front edge of the skateboard platform 2 and the front platform 1. The height difference h is between 4-10mm, with an optimal value of 7mm.

[0071] Multiple weight-reducing holes 21 are also provided on the rear side of the skateboard platform 2. The front side of the skateboard platform 2 is heavier than the rear side. The top edges of the front and rear sides of the skateboard platform 2 are rounded.

[0072] Multiple weight-reducing holes 21 are also provided on the rear side of the skateboard platform 2. The front side of the skateboard platform 2 is heavier than the rear side, which makes the center of the skateboard platform 2 on the front side. When there is no heavy pressure, the skateboard platform 2 will automatically rotate forward, keeping the front side of the skateboard platform 2 pressed down and abutting against the limit block 4.

[0073] The top edges of the front and rear sides of the sliding platform 2 are rounded, creating a stable and smooth connection angle when the sliding platform 2 supports the glass substrate, thus avoiding impact. The rounded corners also ensure smoother guidance.

[0074] The rear end of the skateboard platform 2 is rotatably and flush with the gap between the block platform of the rear end platform 11; the front side of the skateboard platform 2 has a flat edge, and the rear side of the skateboard platform 2 extends backward with multiple protrusions. The protrusions on the rear side of the skateboard platform 2 are clamped in the gap between the rear end platform 11 without contacting each other. The skateboard platform 2 and the protrusions on the rear side form an E-shaped overall structure, and the protrusions and notches of the skateboard platform 2 face the rear end platform 11.

[0075] When the skateboard platform 2 is in a horizontal state, the top of the skateboard platform 2 and the top of the rear platform 11 are on the same plane.

[0076] The skateboard platform 2 does not interact with the front-end platform 1 or the back-end platform 11.

[0077] In use, the glass substrate is first placed on top of the front platform 1, and then pushed horizontally to the rear end by other driving devices, such as... Figure 2 As shown, the height of the skateboard platform 2 is lower than the height of the front platform 1, and the height difference is 0.7mm.

[0078] The glass substrate moves backward slowly, gradually colliding with the sliding platform 2. Upon contact, the platform receives a backward force. Since the platform cannot move horizontally, it can only rotate along the axis 3, thus catching and cushioning the glass substrate. The front end of the platform 2 is tilted downward at an angle, causing the glass substrate to slide backward along the facing surface of the platform 2, as shown in the diagram. Figure 3 As shown, the scale substrate continues to slide backward, and the sliding platform 2, subjected to the downward pressure and impact force of the glass substrate, begins to rotate along the rotation axis 3, forming a shape as shown. Figure 4 As shown, the glass substrate is smoothly transported and slid from the front platform 1 to the rear platform 11. The process is smooth, the structure is convenient and stable, and the glass substrate is connected by the sliding plate platform 2. The structure is simple and compact and does not occupy the space of other components.

[0079] After the conveying is completed, the glass substrate is pressed down by the downward-pressing splitting roller, and then the glass substrate is cut by the cutting wheel. The cutting line is between the limiting block 4 and the front platform 1.

[0080] Once the cutting is complete, the front and rear ends of the glass substrate are disconnected. The rear end continues to move backward, while the front end, which is disconnected, continues to be conveyed to the rear end.

[0081] Once the sliding platform 2 is no longer under the pressure of the glass substrate, because multiple weight-reducing holes 21 are opened at the rear end of the sliding platform 2, the sliding platform 2 will automatically rotate forward and tilt under the action of gravity. The front side of the sliding platform 2 will press against the top of the limiting block 4, rotate back to the initial state of being free from external force, and wait for the next buffering and connection of the glass substrate.

[0082] Meanwhile, an angle sensor 31 is also installed between the rotating shaft 3 and the sliding platform 2. The angle sensor 31 has a conventional structure with two parts, one on the rotating part and one on the fixed part, to detect changes in the rotation angle. This is a common technique for detecting changes in rotation angle and will not be elaborated further. It can monitor the rotation angle of the sliding platform in real time. When the front platform 1 and the rear platform 11 are horizontal, a safe reference value range for the rotation of the sliding platform 2 on the angle sensor 31 is set in advance. When the height difference between the front and rear platforms increases and the rotation angle exceeds the set range, the machine will issue an alarm to notify the engineer to maintain the equipment status in time.

[0083] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
