Description

Technical Field

[0001] This invention relates to a contactless material conveying device, specifically a track-type material conveying device designed based on the principle of air buoyancy fluid dynamics. It is particularly suitable for lightweight materials with high surface quality requirements and susceptible to friction damage, such as ceramic objects, semiconductor wafers, microelectronic components, precision plastic parts, and optical lenses. It can be widely used in the material transfer process of automated production lines such as semiconductor manufacturing, 3C electronic assembly, precision instrument production, and medical device processing. Background Technology

[0002] In the automated production processes of precision manufacturing, the stability, non-destructive nature, and efficiency of material handling directly impact product yield and production efficiency. Traditional contact conveying equipment (such as conveyor belts and roller conveyors) suffers from problems like friction scratches and electrostatic dust adsorption due to direct contact between the material and the conveying medium. For precision components such as semiconductor wafers and optical lenses, such damage can lead to product scrap. To address the shortcomings of contact conveying, the industry has gradually adopted air-floating conveying technology, which uses airflow to create an air cushion that suspends the material, achieving contactless conveying. However, existing air-floating conveying devices still face several technical bottlenecks:

[0003] 1. Insufficient airflow guidance accuracy: Most air flotation devices use straight airflow channels, making it difficult for the airflow direction to simultaneously achieve the dual functions of "suspension support" and "directional propulsion", resulting in unstable material floating, conveying deviation, or speed fluctuation;

[0004] 2. Uneven pressure distribution in the air chamber: An excessively large opening ratio in the airflow channel prevents uniform pressurization of the air chamber, resulting in significant differences in the overall channel output flow. Areas with higher flow rates are prone to excessive impact on the channel walls, causing component wear, or blockage due to excessive tilting. Areas with lower flow rates cause component stagnation. To compensate for insufficient forward momentum in these areas, the total input airflow must be increased, indirectly leading to more severe component wear and blockage in areas with higher flow rates.

[0005] 3. High Energy Consumption: To maintain output power throughout the entire flow channel, a large amount of gas is required for auxiliary propulsion, resulting in excessive consumption of pressurized air in conventional air rails. To address the shortcomings of traditional technologies, the industry urgently needs a waterproofing technology that is easy to construct, highly adaptable, durable, and simple to maintain, in order to overcome the application bottlenecks of existing waterproofing methods and meet the waterproofing needs of various scenarios and high requirements.

[0006] For example, Taiwan's patent TWI687543, "Air-floating Conveyor," discloses a device that suspends materials by ejecting airflow through air holes. However, its airflow channel is a circular straight hole, and the airflow direction only has an upward component. An additional pushing module is required to move the material, resulting in a complex structure and the additional module being prone to interference with the material. Therefore, developing an air-floating conveying device with precise airflow guidance, low pressure loss, flexible structure, and easy maintenance has become an urgent need in the precision manufacturing industry. Summary of the Invention

[0007] Therefore, the main objective of this invention is to overcome the shortcomings of existing air-floating conveying technology and provide an air-floating track conveying device, specifically including:

[0008] 1. Achieve integrated control of airflow "suspension support" and "directional propulsion" to ensure stable material floating and precise conveying direction;

[0009] 2. Optimize the structural design of the air chamber and airflow channel to reduce airflow pressure loss and improve energy utilization efficiency; and

[0010] 3. Avoid contact between the material and any mechanical parts, and ensure that the material surface is free of scratches and dust.

[0011] To achieve the above objectives, the present invention mainly provides an air-floating track conveying device for conveying multiple materials by air flotation.

The first guide vane is disposed between the first support structure and the second support structure and is secured to the first support structure and the second support structure by multiple fasteners. The left and right sides of the first guide vane each have multiple first airflow grooves as airflow channels, so that the upper surface of the first guide vane forms an air-floating track. The airflow guided by the first airflow grooves has a first upward component and a first leftward component. The airflow flows through the first air chamber to the multiple first airflow grooves on the left side of the first guide vane to act on the left side of the lower surface of the multiple materials. At the same time, the airflow flows through the second air chamber to the multiple first airflow grooves on the right side of the first guide vane to act on the right side of the lower surface of the multiple materials, so that the multiple materials float upward and move to the left to the discharge port.

[0012] In one embodiment of the present invention, the air-floating track conveying device further includes a first side baffle, a first outer shell, and a second side baffle. The first side baffle is disposed on the upper side of the first support structure. The first outer shell is disposed on the upper side of the first side baffle. The second side baffle is disposed on the upper side of the second support structure.

[0013] In one embodiment of the present invention, the plurality of first airflow grooves are one or a combination of an inverted L-shape, a diagonal line shape, and a zigzag line shape, and are evenly distributed on the left and right sides of the first guide vane.

[0014] In one embodiment of the invention, the width of each of the first airflow grooves is between 0.05 mm and 0.2 mm, and the depth is between 0.01 mm and 0.1 mm.

[0015] In one embodiment of the present invention, the distance between each of the first airflow grooves is between 0.2 mm and 1 mm.

[0016] To achieve the above objectives, the present invention further provides an air-floating track conveying device for conveying multiple materials by air flotation. The air-floating track conveying device includes a base, an air supply device, a first support structure, a second support structure, a first guide vane, a second guide vane, and a partition.

The baffle plate is positioned between the first and second guide vanes. The baffle plate contains a third air chamber and is secured to the first and second support structures by multiple fasteners. The baffle plate has a predetermined width, through which airflow flows into the third air chamber. The airflow passes through the first and third air chambers to the multiple first airflow grooves on the left and right sides of the first guide vane, acting on the left side of the lower surface of the multiple materials. Simultaneously, the airflow passes through the second and third air chambers to the multiple second airflow grooves on the left and right sides of the second guide vane, acting on the right side of the lower surface of the multiple materials, causing the materials to float upwards and move leftwards to the discharge port.

[0017] The plurality of first airflow grooves are one of an inverted L-shape, a diagonal line shape, and a zigzag line shape, or a combination thereof, and are evenly distributed on the left and right sides of the first guide vane.

[0018] The plurality of second airflow grooves are one of the following: inverted L-shape, oblique line shape, and zigzag line shape, or a combination thereof, and are evenly distributed on the left and right sides of the second guide vane.

Figure 2 This is a three-dimensional exploded view of the air-floating track conveying device of the present invention. Figure 3 This is a detailed schematic diagram of the first airflow groove of the first guide vane of the present invention.

Figure 6This is another cross-sectional view of the airflow operation of the air-floating track conveying device of the present invention. As shown in the figure, the present invention provides an air-floating track conveying device 100 for conveying multiple materials TA by air flotation. The air-floating track conveying device 100 includes a base 110, an air supply device 120, a first support structure 130, a first guide vane 140, a second support structure 150, and a second guide vane 160. The upper surface of the base 110 has a main air inlet 112. The air supply device 120 is disposed on the side of the base 110 and is used to provide an airflow to the main air inlet 112. The first support structure 130 is disposed on the upper side of the base 110 and has a first air chamber 132 therein. The bottom opening 132B of the first support structure 130 is connected to the main air inlet 112 to allow airflow to enter the first air chamber 132. The second support structure 150 is disposed on the upper side of the base 110 and has a second air chamber 152 therein. The first guide vane 140 has a first air guide hole 141 and is connected to the second air chamber 152 to allow airflow into the second air chamber 152. The first guide vane 140 is disposed between the first support structure 130 and the second support structure 150, and is locked to the first support structure 130 and the second support structure 150 by a plurality of fasteners. The left and right sides of the first guide vane 140 have a plurality of first airflow grooves 142 as airflow channels, so that the upper surface of the first guide vane 140 forms an air buoyancy track, wherein the airflow guided by the first airflow grooves 142 has a first upward component and a first leftward component. The airflow flows through the first air chamber 132 to the plurality of first airflow grooves 142 on the left side of the first guide vane 140 to act on the left side of the lower surface of the plurality of materials TA, and at the same time the airflow flows through the second air chamber 152 to the plurality of first airflow grooves 142 on the right side of the first guide vane 140 to act on the right side of the lower surface of the plurality of materials TA, so that the plurality of materials TA float upward and move to the left to the discharge port.

[0040] The first embodiment of the air-floating track conveying device 100 of the present invention will be further described below.

[0041] Base 110: As the overall load-bearing foundation of the device, it can be made of high-strength aluminum alloy, which has the characteristics of being lightweight, highly rigid, and corrosion-resistant. The main air inlet 112 is located along the length of the base 110.

[0042] Air supply device 120: Compressed air can be selected and a pressure regulating valve can be equipped to precisely adjust the air pressure according to the weight of the material.

[0043] Electromagnetic switch 10: Connected in series in the pipeline between the air supply device 120 and the main air inlet 112, it can be equipped with a high-pressure resistant, high-response solenoid valve to supply airflow in a pulse control manner. Electromagnetic switch 10 can be equipped with an independent control module, and the pulse period can be adjusted via PLC signals. Because the material TA may be suspended and swayed during its movement in the channel of the preset size, causing movement interference between the side of the material TA and the left and right side walls of the material TA, and the continuous output airflow cannot eliminate this interference, pulsed airflow is used to help the moving material TA present a high-frequency oscillating posture for output to the outlet end.

[0044] First support structure 130: Located on the upper side of base 110. First support structure 130 is made of 304 stainless steel, and its internal first air chamber 132 is a rectangular cavity. The bottom opening 132B of the first support structure 130 is coaxially aligned with the main air inlet 112, and the edge of the bottom opening 132B may have an annular groove for installing an O-ring seal to further enhance the sealing effect. The first air chamber 132 has an elongated opening.

[0045] The second support structure 150 is symmetrically arranged with the first support structure 130 along the center line of the base 110, and its structure and material are completely identical to those of the first support structure 130. Its internal second air chamber 152 has the same volume as the first air chamber 132, and the second air chamber 152 is positioned opposite to the first air chamber 132. The distance between them matches the width of the first guide vane 140, ensuring that the airflow can be completely guided into the first airflow groove 142.

[0046] First guide vane 140: disposed between first support structure 130 and second support structure 150. First air guide hole 141 of first guide vane 140 is a circular hole, opened at a point in the length direction of first guide vane 140, and connected to the air inlet of second air chamber 152.

[0047] First airflow grooves 142 are respectively disposed on the left and right surfaces of the first guide vane 140, serving as the core guiding channels for airflow. The shape of the plurality of first airflow grooves 142 can be one or a combination of an inverted L-shape, a diagonal line shape, or a zigzag line shape. The width of each first airflow groove 142 is 0.05 mm to 0.2 mm (preferably 0.1 mm), the depth is 0.01 mm to 0.1 mm (preferably 0.05 mm), and the spacing between two adjacent first airflow grooves 142 is 0.2 mm to 1 mm (preferably 0.5 mm). Multiple first airflow grooves 142 are evenly distributed on the left and right sides of the first guide vane 140, and the extension direction of the grooves is consistent.

[0048] After the air supply device 120 is activated, the electromagnetic switch 10 supplies airflow in a pulse control mode according to a preset program. The pulsed airflow flows into the first air chamber 132 through the main air inlet 112 and the bottom opening 132B. The volume design of the first air chamber 132 can play a pressure buffering role, keeping the air pressure in the air chamber stable within the set range. Part of the airflow flows into the second air chamber 152 through the first air guide hole 141, ensuring that the air pressure in the second air chamber 152 is consistent with that in the first air chamber 132.

[0049] Subsequently, the airflow in the first air chamber 132 flows evenly into the first airflow groove 142 on the left side of the first guide vane 140, and the airflow in the second air chamber 152 flows into the first airflow groove 142 on the right side of the first guide vane 140. When the airflow flows along the oblique first airflow groove 142, due to the guiding effect of the groove, a "first upward component" and a "first leftward component" are generated simultaneously. The first upward component provides vertical buoyancy, causing the material TA to float upward to a stable height of 0.1-0.5mm, detaching from the surface of the air flotation track GT. The first leftward component provides horizontal thrust, propelling the material TA smoothly forward to the left along the air flotation track GT. Due to the pulse control of the electromagnetic switch 10, the airflow is intermittently ejected, and the thrust acts periodically on the material TA, which not only avoids the material from deviating due to excessive continuous thrust, but also saves 30%-50% of air source consumption; finally, under the combined action of the stable air cushion and the intermittent thrust, the material TA is smoothly conveyed to the discharge port, with no contact, no friction, and no static electricity accumulation during the conveying process.

[0050] [Second Embodiment]

[0051] Please refer to Figures 7 to 9 As shown, Figure 7 This is an exploded perspective view of another embodiment of the air-floating track conveying device of the present invention. Figure 8 This is a partial exploded perspective view of another embodiment of the air-floating track conveying device of the present invention. Figure 9This is a cross-sectional view of another embodiment of the airflow operation of the air-floating track conveying device of the present invention. As shown in the figure, the embodiment of the present invention provides an air-floating track conveying device 100, including a base 110, an air supply device 120, a first support structure 130, a second support structure 150, a first guide vane 140, a second guide vane 160, and a partition 190. The following describes the differences from the first embodiment: the first guide vane 140 has a first air guiding hole 141. The first guide vane 140 is disposed between and adjacent to the first support structure 130 and the second support structure 150. The left and right sides of the first guide vane 140 each have a plurality of first airflow grooves 142 as airflow channels, so that the upper surface of the first guide vane 140 forms an air-floating effect, wherein the airflow guided by the first airflow grooves 142 has a first upward component and a first leftward component. The second guide vane 160 has a second air guide hole 161 and is connected to the second air chamber 152 to allow airflow into the second air chamber 152. The second guide vane 160 is disposed between the first support structure 130 and the second support structure 150 and is adjacent to the second support structure 150. The left and right sides of the second guide vane 160 have a plurality of second airflow grooves 162 as airflow channels to form an air flotation effect on the upper surface of the second guide vane 160. The airflow guided by the second airflow grooves 162 has a second upward component and a second leftward component.

[0052] Furthermore, the partition 190 has a partition through hole 191 and is connected to the first air guide through hole 141 and the second air guide through hole 161 on the left and right sides respectively. The partition 190 is disposed between the first guide plate 140 and the second guide plate 160. The partition 190 has a third air chamber 192 and is secured to the first support structure 130 and the second support structure 150 by a plurality of fasteners. The partition 190 has a preset width AW, wherein the airflow flows into the third air chamber 192 through the partition through hole 191. The airflow flows through the first air chamber 132 and the third air chamber 192 to the multiple first airflow grooves 142 on the left and right sides of the first guide vane 140 to act on the left side of the lower surface of the multiple materials TA. At the same time, the airflow flows through the second air chamber 152 and the third air chamber 192 to the multiple second airflow grooves 162 on the left and right sides of the second guide vane 160 to act on the right side of the lower surface of the multiple materials TA, so that the multiple materials TA float upward and move to the left to the discharge port.

[0053] Partition 190: As an intermediate support and airflow transfer unit, partition 190 has a partition through hole 191 at its center, which is coaxially arranged with the first air guide through hole 141 and the second air guide through hole 161 to facilitate airflow.

[0054] The third air chamber 192 is formed inside the partition 190 and is a rectangular cavity. It faces the first airflow groove 142 of the first guide vane 140 and the second airflow groove 162 of the second guide vane 160 respectively, ensuring that the airflow can be evenly supplied to the grooves of the guide vanes on both sides.

[0055] The airflow output from the air supply device 120 is controlled by the electromagnetic switch 10 to generate pulses, flowing into the first air chamber 132 through the main air inlet 112 and the bottom opening 132B. The airflow in the first air chamber 132 is divided into two paths: one path flows into the first airflow groove 142 on the left side of the first guide vane 140, and the other path flows through the first air guide through-hole 141 into the partition through-hole of the partition 190, and then into the third air chamber 192. Part of the airflow in the third air chamber 192 is replenished to the first airflow groove 142 on the right side of the first guide vane 140 via the left side, and the other part flows into the second air chamber 152 through the second air guide through-hole 161. Similarly, the airflow in the second air chamber 152 is divided into two paths: one path flows into the second airflow groove 162 on the right side of the second guide vane 160, and the other path replenishes the second airflow groove 162 on the left side of the second guide vane 160 via the right side of the third air chamber 192. The airflow guided by the first airflow groove 142 has a first upward component and a first leftward component, while the airflow guided by the second airflow groove 162 has a second upward component and a second leftward component. The upward components of both components work together on the lower surface of the material TA to ensure a stable floating height (0.1-0.5mm). The superposition of the leftward components provides a more uniform and sustained thrust, suitable for conveying materials over long distances or with large weights (achieved by adding baffles and guide vane modules). The third air chamber 192 of the baffle 190 can provide airflow transfer and pressure compensation, avoiding insufficient buoyancy caused by air pressure attenuation during long-distance conveying, and ensuring that the floating height and forward speed of the material are uniform throughout the entire conveying section.

[0056] In summary, the air-floating track conveying device disclosed in this invention can bring the following benefits:

[0057] 1. Non-contact conveying, completely protecting materials: The air cushion achieves complete non-contact between the material and the air-floating track, with no friction or squeezing during the conveying process, reducing the surface scratch rate of materials from 15%-20% in traditional conveying to 0%; at the same time, the oil-free air supply and anti-static design greatly improve the conveying yield of precision materials.

[0058] 2. Pulse airflow control, balancing energy saving and precision: The electromagnetic switch's pulse cycle design, such as "6ms on, 6ms off", ensures high air source utilization and the pulse thrust can prevent excessive material drift.

[0059] 3. Optimized airflow channels for excellent conveying stability: The shape of the airflow channels has been systematically tested and optimized to achieve the best balance between the upward and forward components of the airflow, eliminating problems such as jamming, offset, or overturning, and ensuring high conveying speed stability.

[0060] 4. Modular structure with strong flexibility and adaptability: The first and second support structures, guide vanes, baffles, and other components are all modularly designed, allowing for the addition or reduction of baffles and guide vanes according to the conveying distance; and all components are connected by standardized screws; and

[0061] 5. Adjustable conveying speed, suitable for various materials: By adjusting the output pressure of the air supply device or the pulse period of the electromagnetic switch, the conveying speed can be continuously adjusted between 1-10cm / s, which can be adapted to various materials and has a wide range of applications.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the invention. Therefore, all equivalent variations or modifications made in accordance with the features and spirit of the present invention should be included within the protection scope of the present invention.
