[0030] The air flotation conveying apparatus 100 of the present invention is used to transport a thin object 200. The air flotation conveying apparatus 100 comprises a processing device 1, multiple air flotation devices 2, a drive device 3, and multiple auxiliary devices 4. The number of air flotation devices 2 and the number of auxiliary devices 4 included in the air flotation conveying apparatus 100 can be increased or decreased based on actual needs. The embodiment shown in the figure is merely an example. The processing device 1 is electrically connected to each of the air flotation devices 2, the drive device 3, and the auxiliary devices 4. The processing device 1 is, for example, a computer or microprocessor.

[0031] The air flotation device 2 can be controlled by the processing device 1 to blow air, causing the thin object 200 to float a predetermined distance above a top surface 211 of the air flotation device 2. In this embodiment, multiple air flotation devices 2 are arranged spaced apart from each other. In different embodiments, multiple air flotation devices 2 can also be arranged adjacent to each other. In different embodiments, the air flotation conveying apparatus 100 can also include only a single air flotation device 2.

[0032] Each flotation device 2 comprises, for example, a main body 21, a plurality of air holes 22, and an air blowing source. The main body 21 has a top surface 211 formed with the plurality of air holes 22. The air blowing source is connected to the main body 21 and is configured to supply air, which is then blown outward through the plurality of air holes 22. The multiple flotation devices 2 are primarily configured to collectively blow air toward one side of a thin object 200, causing the thin object 200 to levitate above the top surface 211 of each flotation device 2.

[0033] The driving device 3 includes a plurality of driving wheels 31, which are used to abut against the thin object 200. The processing device 1 can control any one of the driving wheels 31 to rotate to drive the thin object 200 to move. In other words, the two sides of the thin object 200 to be transported can be disposed on the plurality of driving wheels 31, while the plurality of air flotation devices 2 are correspondingly located below the thin object 200. During the transportation process, the plurality of air flotation devices 2 will simultaneously blow air toward one side of the thin object 200, causing the thin object 200 to suspend above the air flotation devices 2. At the same time, the thin object 200 will also be driven by the plurality of driving wheels 31 to move relative to the plurality of air flotation devices 2.

[0034] The air flotation conveying apparatus 100 of the present invention is suitable for conveying thin objects with a thickness of less than 1 mm, particularly thin objects with a thickness between 0.3 and 0.7 mm. The two sides of such a thin object 200 are disposed on a plurality of drive wheels 31. When the plurality of air flotation devices 2 are not activated, due to the thinness of the thin object 200, portions of the thin object 200 may deform under the action of gravity and contact the top surface 211 of the air flotation devices 2. Therefore, the provision of the plurality of air flotation devices 2 prevents portions of the thin object 200 from contacting the air flotation devices 2 during conveyance by the plurality of drive wheels 31. For example, in the case of a thin object 200 with a thickness between 0.3 and 0.7 mm, the plurality of air flotation devices 2 may, for example, cause the thin object 200 to levitate approximately 2 mm above the top surface 211.

[0035] Each auxiliary device 4 includes a support structure 41, a roller 42, a detection module 43, an auxiliary support structure 44, and an auxiliary roller 45. In different embodiments, each auxiliary device 4 may not include the auxiliary support structure 44 and the auxiliary roller 45.

[0036] The support structure 41 is fixed to one side of the main body 21 of the air flotation device 2. In actual application, the support structure 41 can be detachably mounted on one side of the main body 21 using screws or other components, and the position of the support structure 41 fixed to the main body 21 can be adjusted according to actual needs.

[0037] The roller 42 is rotatably mounted on the support structure 41. The maximum vertical distance between the roller 42 and the top surface 211 is less than a predetermined distance. Therefore, when the thin object 200 is suspended on the air flotation device 2, the thin object 200 does not contact the roller 42. The predetermined distance is the predetermined distance required to keep the thin object 200 suspended above the top surface 211 of the air flotation device 2. For example, in an application scenario where the thickness of the thin object 200 is 0.3 to 0.7 mm, the predetermined distance may be 2 mm.

[0038] The detection module 43 is used to detect whether the roller 42 is rotating and generate a rotation signal 4331 when the roller 42 rotates. The detection module 43 can be implemented in various ways, without limitation, as long as it can detect whether the roller 42 is rotating. For example, the detection module 43 can include a Hall effect sensor, an accelerometer, etc.

[0039] When the amount of air blown by any of the air flotation devices 2 is insufficient, causing the distance between at least one area of ​​the thin object 200 facing the top surface 211 and the top surface 211 to be less than a predetermined distance, each roller 42 is able to support the thin object 200, and the detection module 43 will correspondingly generate a rotation signal 4331 and transmit the rotation signal 4331 to the processing device 1. After receiving the rotation signal 4331, the processing device 1 will transmit a stop signal 11 to the control drive device 3 to stop the operation of the drive device 3.

[0040] More specifically, when each air flotation device 2 is operating normally, the air blown out by each air hole 22 of each air flotation device 2 will be able to collectively allow the thin object 200 to be well suspended above the top surface 211 of each air flotation device 2, and the distance between the bottom surface 201 of the thin object 200 facing the top surface 211 and each top surface 211 will be maintained within a preset distance ± the error value. Although the distance between the thin object 200 and the top surface 211 may vary, the thin object 200 will not come into contact with the top surface 211.

[0041] Continuing from the above, when the amount of air blown out by any of the air flotation devices 2 is insufficient, the area of ​​the thin object 200 located above the air flotation device 2, or above the air holes 22, will sink toward the top surface 211 of the air flotation device 2 (that is, in the negative Z-axis direction in the figures) due to its own weight. In this case, the bottom surface 201 of the thin object 200 will abut against the plurality of rollers 42, which ensure that the thin object 200 does not contact the top surface 211. When the thin object 200 contacts the rollers 42, since the driving wheel 31 is still rotating, the thin object 200 is still driven by the driving wheel 31 and moves relative to the air flotation device 2. Therefore, the rollers 42 in contact with the thin object 200 are driven by the thin object 200 and rotate.

[0042] When the roller 42 rotates, the corresponding detection module 43 will generate a corresponding rotation signal 4331 , causing the processing device 1 to control the driving device 3 to stop running, so that relevant personnel can intervene in real time to repair the air flotation device 2 .

[0043] It should be emphasized that because the roller 42 is pivotally connected to the support structure 41, even if the air flotation device 2 is running low on air and the drive device 3 has not yet stopped operating, the thin object 200 can still be driven by the drive wheel 31 and moved relative to the air flotation device 2 via the roller 42 without causing damage to the thin object 200. In other words, if the roller 42 were replaced with a fixed component, then even if the air flotation device 2 is running low on air and the drive device 3 has not yet stopped operating, the thin object 200 would still be driven by the drive device 3, and the fixed component could potentially cause damage to the thin object 200.

[0044] In one embodiment, each flotation device 2 may be provided with a detection module at a predetermined interval, and when each detection module 43 transmits a rotation signal 4331 to the processing device 1, the detection module 43 may also transmit an identification data to the processing device 1. The processing device 1 may, for example, indicate the position of the detection module 43 that sends the rotation signal on a management interface displayed on a display, thereby facilitating the relevant personnel to inspect the specific flotation device 2.

[0045] like Figure 5 and Figure 6 As shown, in one specific example, each roller 42 may include at least one through-hole 421 extending through the roller 42. The detection module 43 may include a light emitter 431, a light receiver 432, and a processor 433. The light emitter 431 and the light receiver 432 are disposed on either side of the roller 42. When the through-hole 421 of the roller 42 is located between the light emitter 431 and the light receiver 432, the light receiver 432 receives the light beam emitted by the light emitter 431 and generates a sensing signal 4321.

[0046] When the roller 42 is driven to rotate, the light receiver 432 will intermittently generate a sensing signal 4321, and the processor 433 will intermittently receive the sensing signal 4321. When the processor 433 intermittently receives the sensing signal 4321, the processor 433 will generate a rotation signal 4331 and transmit the rotation signal 4331 to the processing device 1.

[0047] As described above, when the air volume of the air flotation device 2 is insufficient, the thin object 200 will contact the roller 42. Since the thin object 200 is still driven by the driving device 3, the thin object 200 will drive the roller 42 to rotate. When the roller 42 rotates, the light beam emitted by the light emitter 431 will be able to pass through the through hole 421 of the roller 42 and enter the light receiver 432, causing the processor 433 to transmit the rotation signal 4331 to the processing device 1.

[0048] As described above, if roller 42 only has a single perforation 421 and drive device 3 moves thin object 200 very slowly, it is possible that even if air flotation device 2 is already running low on air, processing device 1 may not yet control drive device 3 to stop operating because perforation 421 has not yet moved between light emitter 431 and light receiver 432. Conversely, if roller 42 has multiple perforations 421, even a slight rotation of roller 42 could cause processing device 1 to control drive device 3 to stop operating, resulting in frequent misjudgments.

[0049] Therefore, after repeated testing and implementation, the inventors of the present invention discovered that when the drive wheel 31 drives the thin object 200 at a speed between 35 and 45 meters per minute, setting the number of perforations 421 on the roller 42 to 1 or 2 not only allows the processing device 1 to relatively quickly stop the drive device 3 but also significantly reduces the probability of misjudgment. Conversely, when the drive wheel 31 drives the thin object 200 at a speed between 25 and 30 meters per minute, the roller 42 preferably has 3 to 6 perforations 421; and when the drive wheel 31 drives the thin object 200 at a speed between 5 and 20 meters per minute, the roller 42 preferably has 7 to 10 perforations 421.

[0050] Each auxiliary support structure 44 is fixed to the flotation device 2, and each auxiliary roller 45 is rotatably connected to an auxiliary support structure 44. The maximum vertical distance between the auxiliary roller 45 and the top surface 211 is less than a predetermined distance. When the air volume of the flotation device 2 is insufficient, causing the distance between at least one area of ​​the thin object 200 and the top surface 211 to be less than the predetermined distance, the rollers 42 and the auxiliary rollers 45 can jointly support the thin object 200. The auxiliary rollers 45 are only used to assist in supporting the thin object 200 when the air volume of the flotation device 2 is insufficient. The auxiliary support structures 44 are not equipped with the aforementioned detection module 43. In other words, in practice, relevant personnel can install multiple auxiliary rollers 45 and auxiliary support structures 44 based on the size of the thin object 200 to ensure that the thin object 200 does not contact the top surface 211 of the flotation device 2 when the air volume of any flotation device 2 is insufficient.

[0051] It is worth noting that in the prior art, the flotation platform only includes a single platform, which is connected to a single air supply source. Therefore, if the air supply source malfunctions, thin objects will easily come into direct contact with the platform, thereby damaging the thin objects. In contrast, the air flotation conveying equipment 100 of the present invention includes multiple flotation devices 2, each of which can be connected to an independent air supply source. Therefore, in practice, the problem of all flotation devices 2 failing simultaneously is less likely to occur. Moreover, the design of multiple flotation devices 2 allows relevant personnel to install the auxiliary device 4 on a specific flotation device 2 as needed, so that the roller 42 can be located below the middle area of ​​the thin object 200.

[0052] It is worth mentioning that the auxiliary device 4 included in the air flotation conveying equipment 100 of the present invention can also be manufactured or sold separately, and the auxiliary device 4 is not limited to being manufactured or sold together with other components of the air flotation conveying equipment 100 .

[0053] See also Figure 7 , which is a block diagram of another embodiment of the air flotation conveying device of the present invention. The main difference between the air flotation conveying device 100 of this embodiment and the previous embodiment is that the detection module 43A of the air flotation conveying device 100 includes a processor 43A1 and a detector 43A2. Detector 43A2 is used to detect the vertical distance between the thin object 200 suspended on the air flotation device 2 and the air flotation device 2, and generates a detection signal 43A3 accordingly.

[0054] When the air volume of the flotation device 2 is insufficient, causing the distance between at least one area of ​​the thin object 200 and a top surface 211 of the flotation device 2 to be less than a predetermined distance, the rollers 42 are able to support the thin object 200. The processor 43A1, based on the detection signal 43A3, determines that the vertical distance between the thin object 200 and the flotation device 2 is less than the predetermined distance. The processor 43A1 then transmits a stop signal 11 to the processing device 1, causing the processing device 1 to control the drive device 3 to stop operating. In other words, the rollers 42 of this embodiment are only used to support the thin object 200 and do not interact with the detection module 43A. More specifically, the function of the rollers 42 of this embodiment is identical to that of the auxiliary rollers 45 of the aforementioned embodiment.

[0055] In summary, the flotation conveying equipment of the present invention can ensure that thin objects will not contact the top surface of the flotation device through the design of the auxiliary device when the flotation device is short of air, thereby ensuring that the thin objects are not easily damaged. In addition, the detection module will also transmit a signal to the processing device, causing the processing device to stop the operation of the driving device, thereby greatly ensuring that the thin objects are not damaged.

[0056] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made using the contents of the present invention specification and drawings are included in the protection scope of the present invention.
