Description

Technical Field

[0001] This specification relates to the technical field of conveying mechanisms, specifically to an air blowing mechanism and a conveying mechanism. Background Technology

[0002] Conveying mechanisms for transporting flexible products can include robotic arm conveying mechanisms, conveyor belt conveying mechanisms, and air-floating conveying mechanisms. Robotic arm conveying mechanisms achieve gripping and positioning through servo systems, but the end effector's clamping force control precision is insufficient, easily causing physical damage to flexible products during gripping. During dynamic transfer, due to robotic arm vibration or path deviation, flexible products may be damaged due to non-uniform or excessive deformation. Conveyor belt conveying mechanisms and air-floating conveying mechanisms can have multiple stations, but gaps or height differences may exist between adjacent stations. Flexible products, under the influence of gravity, may sag in an arc across these gaps, and the sagged portion may scrape or collide with the sides of adjacent conveyor mechanisms, leading to breakage and affecting product quality and production efficiency.

Detailed Implementation

[0037] To more clearly illustrate the technical solutions of the embodiments in this specification, the embodiments will be described in detail below with reference to the accompanying drawings. Obviously, the content described below are some examples or embodiments of this specification. For those skilled in the art, without creative effort, the technical solutions or means disclosed in this specification can be applied to other scenarios based on this technical content.

[0038] It should be understood that the terms "system," "device," "equipment," "part" and / or "component," "unit" and / or "module" used in this specification are a method of distinguishing different components, elements, parts, sections, or assemblies at different levels. However, if other words can achieve the same purpose, they may be replaced by other expressions.

[0039] Unless otherwise specified, the technical terms used to describe components, elements, etc. in this specification are not singular but may include plural. Generally speaking, terms such as "comprising" or "including" only indicate that explicitly identified steps, elements, or components are included, and these steps, elements, and components do not constitute an exclusive list, as the described method or apparatus may also include other steps or components.

[0040] In the description of this specification, it should be understood that the directional descriptions, such as up, down, front, back, left, and right, indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. These descriptions are for the convenience of describing this application and for simplification, 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 limitations on this application. In the description of this specification, unless otherwise expressly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly. Those skilled in the art can reasonably determine the specific meaning of the above terms in this specification in conjunction with the specific content of the technical solution.

[0041] As manufacturing technology advances, the thickness of flexible products (such as flexible screens and flexible screen wafers) is decreasing, leading to increasingly stringent requirements for the flatness accuracy of conveying mechanisms used to transport these products. In some related embodiments, conveying mechanisms for transporting flexible products may include robotic arm conveying mechanisms, suction cup conveying mechanisms, conveyor belt conveying mechanisms, and air-floating conveying mechanisms. While robotic arm and suction cup conveying mechanisms can achieve gripping and positioning through servo systems, the end effector's clamping force control accuracy is insufficient, easily causing physical damage to the flexible product during gripping (e.g., surface indentations or microcracks). During dynamic transfer, due to robotic arm vibration or path deviation, the flexible product may be damaged due to non-uniform or excessive deformation. The conveyor lines of conveyor belt conveyor and air flotation conveyor can include conveyor mechanisms with multiple stations. However, it is difficult to achieve seamless connection between the conveyor mechanisms of two adjacent stations. There may be gaps or height differences between the conveyor mechanisms. Flexible products bend under the action of gravity in the gaps between stations and produce arc-shaped droops. The drooping parts may scratch or collide with the sides of the conveyor mechanisms of adjacent stations, resulting in damage and breakage, which affects product quality and production efficiency.

[0042] Figure 1 These are schematic diagrams of the conveying mechanism in some related embodiments. Figure 2 yes Figure 1 A magnified view of a portion of the image. See also... Figure 1 , Figure 2As shown, in some related embodiments, the conveying line of the conveying mechanism (e.g., an air flotation conveying mechanism) may include a first conveying mechanism 100 and a second conveying mechanism 200, with a gap 400 between the first conveying mechanism 100 and the second conveying mechanism 200. In some related embodiments, there may also be a height difference between the upper surfaces of the first conveying mechanism 100 and the upper surfaces of the second conveying mechanism 200. In some usage scenarios, the flexible product 300 moves from the first conveying mechanism 100 to the second conveying mechanism 200, passing through the gap 400 during transport. When the flexible product 300 passes through the gap 400, it may sag in an arc shape as shown in the figure due to the lack of lower support, causing the end of the flexible product 300 to scrape or collide with the side of the second conveying mechanism 200 when it arrives at the second conveying mechanism 200, or the flexible product 300 may curl or fall due to the limiting effect of the side of the second conveying mechanism 200 and the continuous conveying of the first conveying mechanism 100.

[0043] Based on this, one or more embodiments of this specification provide an air-blowing mechanism that can be arranged between two conveying mechanisms to prevent the flexible product from sagging due to gravity when passing through the gap between the conveying mechanism stations, thereby improving the manufacturing quality and efficiency of the flexible product. The air-blowing mechanism in one or more embodiments of this specification can also smoothly connect the gap between two adjacent conveying devices of the conveying mechanism.

Figure 4 This is a top view schematic diagram of the air blowing mechanism shown in some embodiments of this specification. Figure 5 This is a schematic diagram of the fluid from a top view of the blowing mechanism shown in some embodiments of this specification. Figure 6 This is a side view schematic diagram of the air blowing mechanism shown according to some embodiments of this specification. See also Figures 3 to 6As shown, in one or more embodiments of this specification, the air blowing mechanism may include: a base 10, a first air nozzle 1 disposed on the base 10, and a second air nozzle 2 disposed on the base 10. In some embodiments, the first air nozzle 1 and the second air nozzle 2 are used to provide a working fluid, such as gas. In some embodiments, the base 10 has a gas outlet 101 for providing working fluid to the outside of the base 10, which may be provided by at least one of the first air nozzle 1 and the second air nozzle 2. In some embodiments, the gas outlet 101 may be arranged between two conveying mechanisms, such as in the gap between the two conveying mechanisms, to provide upward working fluid, thereby providing upward buoyancy to a flexible product passing through the gap and preventing deformation of the flexible product, such as possible arcing or sagging. In some embodiments, the upward buoyancy provided by the gas outlet 101 to the flexible product may also enable the end of the flexible product to be higher than the downstream conveying mechanism during transport from the upstream conveying mechanism to the downstream conveying mechanism, avoiding collision with the downstream conveying mechanism. In some embodiments, the gas outlet 101 may be elongated. In some embodiments, the gas outlet 101 may be a slit. In some embodiments, the gas outlet 101 may fill all or part of the gap between the two conveying mechanisms.

[0045] In some embodiments, the gas outlet 101 has a first reflective wall and a second reflective wall on both sides. In some embodiments, the gas outlet 101 is located between the first reflective wall and the second reflective wall. In some embodiments, the gas outlet 101 is formed between the first reflective wall and the second reflective wall. In some embodiments, the first reflective wall and the second reflective wall may be arranged between two conveying mechanisms. In some embodiments, the first reflective wall may be arranged at one conveying mechanism and the second reflective wall may be arranged at another conveying mechanism. In some embodiments, the first reflective wall and the second reflective wall may be provided by a wall structure on the base 10. In other embodiments, the first reflective wall may be provided by a side wall of one conveying mechanism and the second reflective wall may be provided by a side wall of another conveying mechanism.

[0046] In some embodiments, the base 10 may include: a fixing plate 11, a first side plate 12 disposed on the fixing plate 11, and a second side plate 13 disposed on the fixing plate 11. In some embodiments, the first side plate 12 provides a first reflective wall, and the second side plate 13 provides a second reflective wall.

[0047] In some embodiments, the fixing plate 11 is used to fix it to the conveying mechanism. In some embodiments, the fixing plate 11 can be fixed to an upstream conveying mechanism, a downstream conveying mechanism, or both. In some embodiments, the first side plate 12 and the second side plate 13 can be integrally connected to the fixing plate 11, or fixedly connected to the fixing plate 11 by welding, riveting, bonding, or other methods. In some embodiments, both the first side plate 12 and the second side plate 13 can be perpendicular to the fixing plate 11. In some embodiments, there can be an angle between the first side plate 12 and the fixing plate 11. In some embodiments, there can be an angle between the second side plate 13 and the fixing plate 11. In some embodiments, there can be angles between the first side plate 12 and the fixing plate 11, and between the second side plate 13 and the fixing plate 11. In some embodiments, the distance between the lower parts of the first side plate 12 and the second side plate 13 can be less than the distance between their upper parts. In other embodiments, the distance between the lower parts of the first side plate 12 and the second side plate 13 can be greater than the distance between their upper parts.

[0048] In some embodiments, the first side plate 12 and the second side plate 13 can also be used to fix the first air nozzle 1 and the second air nozzle 2.

[0049] In some embodiments, see Figures 9 to 12 As shown, the first air nozzle 1 is fixedly connected to the first side plate 12. In some embodiments, the air inlet of the first air nozzle 1 is located at the bottom of the fixing plate 11, and the upper part of the first air nozzle 1 (e.g., the air outlet of the first air nozzle 1) passes through the fixing plate 11 and the first side plate 12 and extends into the gap between the first side plate 12 and the second side plate 13. The first side plate 12 can be used to limit the position of the first air nozzle 1, assist in fixing the first air nozzle 1, and prevent the upper part of the first air nozzle 1 from shaking or vibrating.

[0050] In some embodiments, see Figures 9 to 12 As shown, the second air nozzle 2 is fixedly connected to the second side plate 13. In some embodiments, the air inlet of the second air nozzle 2 is located at the bottom of the fixing plate 11, and the upper part of the second air nozzle 2 (e.g., the air outlet of the second air nozzle 2) passes through the fixing plate 11 and the second side plate 13 and extends into the gap between the first side plate 12 and the second side plate 13. The second side plate 13 can be used to limit the position of the second air nozzle 2, assist in fixing the second air nozzle 2, and prevent the upper part of the second air nozzle 2 from shaking or vibrating.

[0051] In one or more embodiments of this specification, see Figures 5 to 7As shown, the first air nozzle 1 faces the second reflective wall, and the second air nozzle 2 faces the first reflective wall, to form a vortex between the first and second reflective walls. In some embodiments, the vortex is a closed or nearly closed circulation structure rotating around a vortex core in a fluid. In some embodiments, the vortex can be a cyclone formed by gas.

[0052] In some embodiments, the first nozzle 1 provides working fluid to the first reflective wall. After colliding with the first reflective wall, the working fluid is reflected upwards, thereby causing the working fluid to tend to move towards the gas outlet 101. In some embodiments, after colliding with the first reflective wall, the working fluid is also split to both sides to form a vortex.

[0053] In some embodiments, the second nozzle 2 supplies working fluid to the second reflector wall. After colliding with the second reflector wall, the working fluid is reflected upwards, thereby giving the working fluid a tendency to move towards the gas outlet 101. In some embodiments, after colliding with the second reflector wall, the working fluid is also split to both sides to form a vortex.

[0054] In some embodiments, the vortex formed by the first air nozzle 1 and the vortex formed by the second air nozzle 2 can be combined. In other embodiments, the first air nozzle 1 and the second air nozzle 2 can each form a separate vortex.

[0055] In some applications, the conveying mechanism has a certain width, so the gap between the upstream and downstream conveying mechanisms is perpendicular to the streamline (e.g., Figure 1 , Figure 2 The nozzles also have a certain width in the front-to-back direction. If multiple nozzles are arranged sequentially in a direction perpendicular to the streamline (e.g., with the nozzle outlets facing upwards), the working fluid provided by the nozzles cannot completely fill the entire area of ​​the gap. Instead, it will create a situation of airflow → gap → airflow → gap in the direction perpendicular to the streamline. This may cause uneven stress on the flexible product, resulting in local deformation of the flexible product. It may also cause one side of the flexible product to lack airflow support, and one end of the product may still collide with the side wall of the downstream conveying mechanism.

[0056] In one or more embodiments of this specification, the first air nozzle 1 and the second air nozzle 2 form a vortex between the first reflective wall and the second reflective wall. Since the vortex rises in a spiral, it can completely fill the entire area of ​​the gap between the two conveying mechanisms, so that the flexible product is subjected to uniform force, avoids local deformation of the flexible product, and at the same time allows the end of the flexible product to be higher than the downstream conveying mechanism, avoiding the collision between the end of the flexible product and the side wall of the downstream conveying mechanism.

[0057] In some embodiments, the pressure on the fluid changes during rotation. For example, when the vortex is at the bottom, it is subjected to greater pressure from the surroundings (greater air pressure formed at the outlet of the first nozzle 1 or the second nozzle 2). As the vortex rises, the external pressure gradually decreases, causing the vortex to gradually increase in size, and the external fluid further converges towards the vortex, thereby further filling the gap between the two conveying mechanisms.

[0058] In some embodiments, eddy currents can be evenly distributed along the edges of the flexible product to prevent the flexible product from bending and deforming downwards.

[0059] In one or more embodiments of this specification, see Figures 4 to 7 As shown, the first air nozzle 1 and the second air nozzle 2 are located on opposite sides of a first plane A, which is situated between a first reflective wall and a second reflective wall. In some embodiments, the first plane A may be parallel to the first and second reflective walls. In some embodiments, the first plane A is located between a first side plate 12 and a second side plate 13. In some embodiments, the first side plate 12 and the second side plate 13 are arranged in parallel, and the first plane A is parallel to both the first side plate 12 and the second side plate 13. In some embodiments, the first side plate 12 and the second side plate 13 are symmetrically arranged with respect to the first plane A.

[0060] In one or more embodiments of this specification, see Figures 2 to 12 As shown, the direction in which the blowing mechanism provides fluid through the air outlet 101 is defined as the first direction Z (e.g., Figure 2 (The vertical direction in the middle), when the air blowing mechanism is installed on the conveying mechanism, the direction perpendicular to the streamline direction is the second direction X (e.g., the vertical direction in the middle). Figure 2 The left and right directions in the middle), the direction parallel to the streamline direction is the third direction Y (e.g. Figure 2 A reference coordinate system is established using the forward and backward directions (in the model). In some embodiments, the first direction Z, the second direction X, and the third direction Y can be perpendicular to each other.

[0061] In some embodiments, the gas outlet 101 is oriented toward a first direction Z, and the gas outlet 101 extends in a second direction X intersecting the first direction Z, with the first plane A parallel to the second direction X.

[0062] In some embodiments, see Figure 6As shown, the air supply direction of the first air nozzle 1 is projected onto the second projection plane YOZ at a first angle α with the first plane A, and the second projection plane YOZ is perpendicular to the second direction X. In some embodiments, the first angle α is configured to allow the fluid supplied by the first air nozzle 1 to be reflected by the first reflective wall, while also giving the reflected fluid an upward tendency (e.g., an upward motion component). In some embodiments, the first angle α can be 40° to 80°. Exemplarily, the first angle α can be 40°, 45°, 50°, 56°, 60°, 66°, 72°, 75°, 78°, or 80°.

[0063] In some embodiments, see Figure 6 As shown, the air supply direction of the second air nozzle 2 has a second included angle β between its projection onto the second projection plane YOZ and the first plane A, and the second projection plane YOZ is perpendicular to the second direction X. In some embodiments, the first included angle α and the second included angle β may be the same or different. In some embodiments, the second included angle β is configured to allow the fluid supplied by the second air nozzle 2 to be reflected by the second reflective wall, while giving the reflected fluid an upward tendency (e.g., an upward motion component). In some embodiments, the second included angle β may be 40° to 80°. Exemplarily, the second included angle β may be 40°, 45°, 50°, 56°, 60°, 66°, 72°, 75°, 78°, or 80°.

[0064] In some embodiments, the first included angle α and the second included angle β may be equal or unequal.

[0065] In one or more embodiments of this specification, see Figure 4 As shown, the projection of the air supply direction of the first air nozzle 1 onto the first projection plane XOY is perpendicular to the first plane A, and the first projection plane XOY is perpendicular to the first direction Z. For example, the projection of the air supply direction of the first air nozzle 1 onto the first projection plane XOY lies on line A1, and line A1 is perpendicular to the first plane A. In this embodiment, because line A1 is perpendicular to the first plane A, the fluid supplied by the first air nozzle 1 can be split to both sides after colliding with the first reflective wall, thereby forming a vortex.

[0066] In some embodiments, the projection of the air supply direction of the second air nozzle 2 onto the first projection plane XOY is perpendicular to the first plane A, and the first projection plane XOY is perpendicular to the first direction Z. For example, the projection of the air supply direction of the second air nozzle 2 onto the first projection plane XOY lies on a straight line A2, which is perpendicular to the first plane A. In this embodiment, because the straight line A2 is perpendicular to the first plane A, the fluid supplied by the second air nozzle 2 can be split to both sides after colliding with the second reflective wall, thereby forming a vortex.

[0067] In this embodiment, the fluid supplied by the first nozzle 1 forms two streams on both sides after colliding with the first reflective wall, and the fluid supplied by the second nozzle 2 forms two streams on both sides after colliding with the second reflective wall. One of the streams formed by the first nozzle 1 can merge with one of the streams formed by the second nozzle 2 to form a vortex.

[0068] In one or more embodiments of this specification, see Figure 13 As shown, the projection of the air supply direction of the first air nozzle 1 onto the first projection plane XOY is inclined relative to the first plane A, and the first projection plane XOY is perpendicular to the first direction Z. For example, the projection of the air supply direction of the first air nozzle 1 onto the first projection plane XOY lies on the straight line B1, and the straight line B1 is inclined relative to the first plane A.

[0069] In some embodiments, the projection of the air supply direction of the second air nozzle 2 onto the first projection plane XOY is inclined relative to the first plane A, and the first projection plane XOY is perpendicular to the first direction Z. For example, the projection of the air supply direction of the second air nozzle 2 onto the second projection plane XOY lies on a straight line B2, and the straight line B2 is inclined relative to the first plane A.

[0070] In this embodiment, the fluid supplied by the first air nozzle 1 changes direction after colliding with the first reflective wall, and the fluid supplied by the second air nozzle 2 changes direction after colliding with the second reflective wall. The fluids supplied by the first air nozzle 1 and the second air nozzle 2 form a vortex after changing direction.

[0071] In this embodiment, the first reflective wall and the second reflective wall can be provided by the first side plate 12 and the second side plate 13, respectively. In this embodiment, the first reflective wall and the second reflective wall can also be provided by other structures besides the first side plate 12 and the second side plate 13. In this embodiment, the first reflective wall and the second reflective wall can be provided by a partition 14 disposed between the first side plate 12 and the second side plate.

[0072] In one or more embodiments of this specification, see Figures 13 to 15 As shown, the base 10 may further include: a partition 14, with one or more partitions 14 disposed between the first side plate 12 and the second side plate 13, the partitions 14 dividing the space between the first side plate 12 and the second side plate 13 to form a plurality of vortex spaces. In some embodiments, each vortex space is provided with a first air nozzle 1 and a second air nozzle 2, and one or more vortices are formed inside each vortex space.

[0073] In some embodiments, each vortex space is provided with a pair of first air nozzles 1 and second air nozzles 2. In other embodiments, each vortex space is provided with two or more pairs of first air nozzles 1 and second air nozzles 2.

[0074] In some embodiments, the partition 14 may provide a first reflective wall and a second reflective wall. In some embodiments, in each vortex space, the first air nozzle 1 may be directed toward one side of the partition, and the second air nozzle 2 may be directed toward the other side of the partition.

[0075] In some embodiments, by adjusting the angle between the projection of the air supply direction of the first air nozzle 1 onto the first projection plane XOY and the first plane A (i.e., the angle between the straight line B1 and the first plane A), the first air nozzle 1 can be directed toward the first reflective wall provided by the first side plate 12, or the first air nozzle 1 can be directed toward the first reflective wall provided by the partition 14.

[0076] In some embodiments, by adjusting the angle of the projection of the air supply direction of the second air nozzle 2 onto the first projection plane XOY relative to the first plane A (i.e., the angle between the straight line B2 and the first plane A), the second air nozzle 2 can be directed toward the second reflective wall provided by the second side plate 13, or the second air nozzle 2 can be directed toward the second reflective wall provided by the partition plate 14.

[0077] In one or more embodiments of this specification, a first air nozzle 1 may be disposed at a partition 14 and facing a first side plate 12. In some embodiments, a second air nozzle 2 may be disposed at another partition 14 and facing a second side plate 13. This creates a vortex in the vortex space formed by the two partitions 14, the first side plate 12, and the second side plate 13.

[0078] In this embodiment, the upper part of the first air nozzle 1 (e.g., the air outlet of the first air nozzle 1) passes through the fixing plate 11 and a partition 14 and extends into the vortex space. In this embodiment, the partition 14 can be used to limit the position of the first air nozzle 1, assist in fixing the first air nozzle 1, and prevent the upper part of the first air nozzle 1 from shaking or vibrating.

[0079] In this embodiment, the upper part of the second nozzle 2 (e.g., the air outlet of the second nozzle 2) passes through the fixing plate 11 and another partition 14 and extends into the vortex space. In this embodiment, the partition 14 can be used to limit the position of the second nozzle 2, assist in fixing the second nozzle 2, and prevent the upper part of the second nozzle 2 from shaking or vibrating.

[0080] In one or more embodiments of this specification, the number of first air nozzles 1 can be multiple. In some embodiments, the multiple first air nozzles 1 are arranged along the second direction X. In some embodiments, the number of second air nozzles 2 can be multiple. In some embodiments, the multiple second air nozzles 2 are arranged along the second direction X. In some embodiments, the first air nozzles 1 and second air nozzles 2 are arranged alternately. In some embodiments, the spacing between two adjacent first air nozzles 1 and second air nozzles 2 in the second direction X can be 4-7 mm. For example, the spacing between two adjacent first air nozzles 1 and second air nozzles 2 in the second direction X can be 4 mm, 4.5 mm, 5 mm, 5.2 mm, 5.5 mm, 5.6 mm, 5.8 mm, 6 mm, 6.6 mm, or 7 mm.

[0081] In some embodiments, the first nozzle 1 and the second nozzle 2 can simultaneously provide working fluid. In some embodiments, the first nozzle 1 and the second nozzle 2 can simultaneously provide working fluid at a constant pressure. In some embodiments, the working fluid at a constant pressure provided by the first nozzle 1 and the second nozzle 2 forms staggered, upward-rotating vortices under the influence of a first included angle α, a second included angle β, and the alternating spacing between the first nozzle 1 and the second nozzle 2. In some embodiments, multiple staggered, upward-rotating vortices cause the edges of the flexible product to float.

[0082] In one or more embodiments of this specification, see Figures 3 to 15 Combination Figure 16 As shown, the blowing mechanism may further include a pressure regulating valve 3, which includes a positive pressure inlet 31 and a positive pressure outlet 32. In some embodiments, the positive pressure inlet 31 is connected to an air source. In some embodiments, the positive pressure outlet 32 ​​is directly or indirectly connected to the first nozzle 1 and / or the second nozzle 2. In some embodiments, the pressure regulating valve 3 is used to control the blowing force of the first nozzle 1 and / or the second nozzle 2. In some embodiments, the pressure regulating valve 3 can also be used to control the moving speed and position of the flexible product during transportation. In some embodiments, the pressure regulating valve 3 is used to adjust the amount of positive pressure fluid provided by the first nozzle 1 and the second nozzle 2.

[0083] In some embodiments, the air blowing mechanism may include a pressure regulating valve 3 connected to a first air nozzle 1 and a second air nozzle 2. In some embodiments, the air blowing mechanism may include two pressure regulating valves 3, one connected to a plurality of first air nozzles 1 and the other connected to a plurality of second air nozzles 2. In some embodiments, the air blowing mechanism may include a plurality of pressure regulating valves 3, with one pressure regulating valve 3 corresponding to each first air nozzle 1. In some embodiments, the air blowing mechanism may include a plurality of pressure regulating valves 3, with one pressure regulating valve 3 corresponding to each second air nozzle 2.

[0084] In some embodiments, the positive pressure outlet 32 ​​of the pressure regulating valve 3 is directly connected to the first air nozzle 1 and / or the second air nozzle 2. In some embodiments, the positive pressure outlet 32 ​​of the pressure regulating valve 3 is connected to the first air nozzle 1 and / or the second air nozzle 2 via a multi-way air blowing device 4.

[0085] In some embodiments, the gas source provides positive pressure gas of 0.3 to 0.9 MPa (e.g., 0.4 MPa, 0.5 MPa, 0.6 MPa, 0.65 MPa, 0.7 MPa, etc.). The positive pressure gas enters the positive pressure inlet 31 of the pressure regulating valve 3 for pressure regulation, and then enters the multi-way blowing device 4 through the positive pressure outlet 32 ​​of the pressure regulating valve 3. The multi-way blowing device 4 enters the first air nozzle 1 and the second air nozzle 2 through pipelines respectively, precisely forming a constant positive pressure gas vortex.

[0086] In some embodiments, the pressure or flow rate of the positive pressure gas provided by the plurality of first gas nozzles 1 may be the same. In some embodiments, the pressure or flow rate of the positive pressure gas provided by the plurality of first gas nozzles 1 may be different. In some embodiments, the pressure or flow rate of the positive pressure gas provided by the plurality of second gas nozzles 1 may be the same. In some embodiments, the pressure or flow rate of the positive pressure gas provided by the plurality of second gas nozzles 2 may be different. In some embodiments, the pressure or flow rate of the positive pressure gas provided by the first gas nozzle 1 and the pressure or flow rate of the positive pressure gas provided by the second gas nozzle 2 may be the same or different.

[0087] In some embodiments, a throttling valve 5 is further provided between the positive pressure outlet 32 ​​of the pressure regulating valve 3 and the first nozzle 1 and / or the second nozzle 2. The pressure or flow rate of the positive pressure gas supplied by each first nozzle 1 can be independently adjusted via the throttling valve 5. Similarly, the pressure or flow rate of the positive pressure gas supplied by each second nozzle 2 can be independently adjusted via the throttling valve 5.

[0088] One or more embodiments of this specification provide a conveying mechanism, see [link to relevant documentation]. Figures 17 to 20 As shown, the conveying mechanism includes the aforementioned air-blowing mechanism. In some embodiments, the conveying mechanism may include a first conveying device 81 and a second conveying device 91, with the air-blowing mechanism disposed between the first conveying device 81 and the second conveying device 91. In some embodiments, the first conveying device 81 and the second conveying device 91 are used to prevent flexible products, such as liquid crystal panels. In some embodiments, the first conveying device 81 and the second conveying device 91 may further be used to convey flexible products. In some embodiments, the air-blowing mechanism may be located below or at the lower part of the gap between the first conveying device 81 and the second conveying device 91, for blowing air onto the lower surface of the flexible product.

[0089] In some embodiments, both the first conveying device 81 and the second conveying device 91 are air-floating platforms. In some embodiments, the air-floating platforms of the first conveying device 81 and the second conveying device 91, in conjunction with an air-floating mechanism, can achieve contactless conveying.

[0090] In some embodiments, the first conveying device 81 may include a first support 82 and a first platform 83 disposed on the first support 82. In some embodiments, the fixing plate 11 of the base 10 may be fixedly connected to the first support 82 of the first conveying device 81, for example, by fixing frame bolts. In some embodiments, the fixing plate 11 of the base 10 may also be fixedly connected to the first platform 83 of the first conveying device 81.

[0091] In some embodiments, the second conveying device 91 may include a second support 92 and a second platform 93 disposed on the second support 92. In some embodiments, the fixing plate 11 of the base 10 may be fixedly connected to the second support 92 of the second conveying device 91, for example, by fixing frame bolts. In some embodiments, the fixing plate 11 of the base 10 may also be fixedly connected to the second platform 93 of the second conveying device 91.

[0092] In some embodiments, the first nozzle 1 and the second nozzle 2 are connected to positive pressure regulating gas through the pressure regulating valve 3, and a certain amount of positive pressure gas is ejected. The two streams of positive pressure gas provided by the first nozzle 1 and the second nozzle 2 form staggered peaks in a limited space (e.g., the space between the first side plate 12 and the second side plate 13, or the space enclosed by the first side plate 12, the second side plate 13 and the partition 14), causing the positive pressure gas to form vortices. The vortices can only rise along the first direction Z in the relatively enclosed space on the side, thereby forming multiple positive pressure gas vortices that cause the edge of the part of the flexible product located in the gap between the first conveying device 81 and the second conveying device 91 to float.

[0093] In some embodiments, the pressure regulating valve may be arranged on the first bracket 82 or the second bracket 92.

[0094] In some embodiments, the working fluid provided by the first air nozzle 1 and the second air nozzle 2 via the pressure regulating valve 3 (and the throttle valve 5) enables the flexible product to be suspended about 200 μm above the first conveying device 81 and the second conveying device 91, for example, 200 μm ± 30 μm.

[0095] In some embodiments, the conveying mechanism may include a control mechanism for identifying the position of the lower surface of the flexible product and dynamically adjusting the pressure regulating valve 3 (and the throttle valve 5) so that the working fluid provided by the first air nozzle 1 and the second air nozzle 2 can suspend the flexible product above the first conveying device 81 and the second conveying device 91 by about 200 μm, for example, 200 μm ± 30 μm.

[0096] In some embodiments, the conveying mechanism may include a control mechanism that dynamically adjusts the pressure regulating valve 3 (and the throttle valve 5) according to preset product information, so that the working fluid provided by the first air nozzle 1 and the second air nozzle 2 can suspend the flexible product above the first conveying device 81 and the second conveying device 91 by approximately 200 μm, for example, 200 μm ± 30 μm. In some embodiments, dynamically adjusting the pressure regulating valve 3 (and the throttle valve 5) according to preset product information may include adjusting the pressure regulating valve 3 (and the throttle valve 5) according to the preset gravity requirements of different positions of the product, so that the buoyancy provided by the working fluid provided by the first air nozzle 1 and the second air nozzle 2 to the product can match the gravity of the product at different positions.

[0097] In some embodiments, after the flexible product is smoothly conveyed by the first air nozzle 1 and the second air nozzle 2, it is suspended and transferred to the downstream conveying mechanism (e.g., the second conveying device 91).

[0098] In some embodiments, the first side plate 12 of the base 10 is lower than the upper surface of the first conveying device 81, and the second side plate 13 of the base 10 is lower than the upper surface of the second conveying device 91.

[0099] In some embodiments, the upper surface heights of the first platform 83 of the first conveying device 81 and the second platform 93 of the second conveying device 91 need to maintain a large area of ​​uniformity. For example, the flatness of the first platform 83 of the first conveying device 81 and the second platform 93 of the second conveying device 91 needs to reach ±3 μm / m to effectively suspend the product flat. See also [link to embodiments]. Figure 21 , Figure 22 As shown, adjustment mechanisms 7 are provided between the first support 82 and the first platform 83 of the first conveying device 81, and between the second support 92 and the second platform 93 of the second conveying device 91. The adjustment mechanisms 7 are used to adjust the flatness of the first platform 83 and the second platform 93.

[0100] In some embodiments, the adjusting mechanism 7 may include a plurality of adjusting screws evenly distributed on the first conveying device 81 and the second conveying device 91. In some embodiments, rotating the adjusting screws can adjust the height of a certain position of the first platform 83 relative to the first support 82. In some embodiments, rotating the adjusting screws can adjust the height of a certain position of the second platform 93 relative to the second support 92.

[0101] In some embodiments, the adjusting screw is rotatably connected to the first bracket 82, with its upper end abutting against the first platform 83. In some embodiments, the adjusting screw is rotatably connected to the second bracket 92, with its upper end abutting against the second platform 93.

[0102] In some embodiments, the pitch of the external thread of the adjusting screw can be 0.5 mm, meaning the height adjustable by rotating 360 degrees can be 500 μm. Therefore, by utilizing the contact between the plane of the adjusting screw and the planes of the first platform 83 and the second platform 93, the local position of the first platform 83 and the second platform 93 can be raised or lowered to adjust the height, thereby achieving a flatness of ±3 μm / m. In some embodiments, the adjustment method of the adjusting screw may include: turning it clockwise to locally raise the first platform 83 or the second platform 93, and turning it counterclockwise to locally lower the first platform 83 or the second platform 93.

[0103] In some embodiments, after adjusting all positions of the first platform 83 and the second platform 93 to achieve a flatness of ±3μm / m, the adjusting screws are tightened to ensure that the adjusted flatness of ±3μm / m does not change.

[0104] The basic concepts have been described above. It is obvious that the detailed disclosure above is merely illustrative and does not constitute a limitation of this specification. Although not explicitly stated herein, various modifications, improvements, and corrections may be made to this specification by those skilled in the art. Such modifications, improvements, and corrections are taught in this specification and therefore remain within the spirit and scope of the exemplary embodiments described herein.
