[0017] Figure 2 It is a partial top view of the air floating plate in the air floating transmission device of the utility model. DETAILED DESCRIPTION

[0018] In order to provide a further understanding of the purpose, structure, features and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0019] Please refer to Figure 1 and Figure 2 , Figure 1 It is a partial schematic diagram of the air floating transmission device of the utility model; Figure 2 FIG. 1 is a partial top view of the air flotation plate in the air flotation transmission device of the utility model. Figure 1 and Figure 2 As shown, the utility model proposes an air-floating transmission device for non-contact transmission of a plate-like component 10 along a transmission direction F1. The plate-like component 10 is, for example, but not limited to, a glass substrate, a light guide plate, etc. The air-floating transmission device comprises an air-floating plate 20, a driving mechanism (not shown), and an air-floating force monitoring mechanism 30. The air-floating plate 20 is provided with a plurality of holes 21. The air flow blown out by the plurality of holes 21 makes the plate-like component 10 float above the air-floating plate 20, so as to avoid direct contact between the plate-like component 10 and the air-floating plate 20. In actual operation, an air source mechanism (not shown) is also provided below the air-floating plate 20. The air source mechanism provides air flow to the air-floating plate 20. By adjusting the gas flow rate provided by the unit, the suspension height of the plate-like component 10 can be adjusted. The driving mechanism is used to drive the plate-like component 10 to move along the transmission direction F1.

[0020] In this embodiment, the air buoyancy monitoring mechanism 30 is installed on one side of the air floating plate 20. The air buoyancy monitoring mechanism 30 includes a roller assembly 31 and a sensor assembly 32. The roller assembly 31 is arranged along the conveying direction F1 of the plate-like element 10 and the upper end of the roller assembly 31 is higher than the upper surface of the air floating plate 20. The sensor assembly 32 is arranged corresponding to the roller assembly 31 and is used to detect whether the roller assembly 31 rotates. Generally, the distance between the upper end of the roller assembly 31 and the upper surface of the air floating plate 20 is a preset safety height d1. In one embodiment, the preset safety height d1 is 0.5 mm. When the distance between the bottom surface of the plate-like element 10 and the upper surface of the air-floating plate 20 is greater than the preset safety height d1, the plate-like element 10 does not touch the roller assembly 31, and the air-floating transmission device operates normally; when the plate-like element 10 touches the upper end of the roller assembly 31 during the transportation process and the roller assembly 31 rotates due to the friction between the roller assembly 31 and the plate-like element 10, that is, the distance between the bottom surface of the plate-like element 10 and the upper surface of the air-floating plate 20 is equal to the preset safety height, at this time, the sensor assembly 32 corresponding to the roller assembly 31 will detect this rotation and issue a warning reminder so that the operator can deal with the abnormal situation in time and eliminate safety hazards, thereby avoiding scratches caused by the plate-like element 10 touching the air-floating plate 20 during the transportation process.

[0021] In this embodiment, continue to refer to Figure 1 and Figure 2 The air buoyancy monitoring mechanism 30 of the utility model further comprises a mounting plate 33, on which a roller assembly 31 is fixed, and the mounting plate 33 further comprises a strip-shaped mounting groove 331, and the mounting plate 33 is fixed to one side of the air floating plate 20 after a fixing element 332 passes through the strip-shaped mounting groove 331. The fixing element 332 is, for example, a screw assembly, and the mounting plate 33 is fixed by drilling a hole on the side of the air floating plate 20 and using the screw assembly. The provision of the strip-shaped mounting groove 331 makes the distance between the upper end of the roller assembly 31 and the upper surface of the air floating plate 20 adjustable, that is, the preset safety height d1 is adjustable, and the user can adjust the distance between the upper end of the roller assembly 31 and the air floating plate 20 according to actual needs. In addition, the fixing method of the mounting plate 33 and the air floating plate 33 is not limited thereto, for example, the air buoyancy monitoring mechanism 30 can also be fixed to the side of the air floating plate 20 by magnetic attraction through the mounting plate 33.

[0022] In one embodiment, the extension direction of the strip-shaped mounting groove 331 forms an angle with the conveying direction F1, and the angle is, for example, 90°. In actual operation, multiple groups of strip-shaped mounting grooves 331 can be provided as needed so that the mounting plate 33 can have a better and more stable fixed state.

[0023] like Figure 2In the embodiment shown, the air buoyancy monitoring mechanism 30 is located on one side of the air floating plate 20 , but the present invention is not limited thereto. In another embodiment, the air floating transmission device of the present invention includes two sets of air buoyancy monitoring mechanisms 30 , which are respectively installed on two opposite sides of the air floating plate 20 .

[0024] In one embodiment, the sensor component 32 is a displacement sensor. Thus, when the plate element 10 touches the upper end of the roller component 31 and causes the roller component 31 to rotate by friction, the sensor component 32 can detect the displacement of the roller component 31 and issue a warning.

[0025] In one embodiment, the sensor component 32 may be provided with an indicator light (such as an LED light), and the warning reminder issued by the sensor component 32 is a flashing red light signal.

[0026] In one embodiment, the buoyancy monitoring mechanism 30 further includes a display component (not shown), which is connected to the sensor component 32. When the plate-like element 10 touches the roller component 31 during transportation and drives the roller component 31 to rotate, the sensor component 32 sends a warning signal to the display component, and the display component displays a first warning content. For example, the display component displays the words "the buoyancy monitoring mechanism detects an abnormality" on its screen to promptly remind the operator of abnormal conditions in the air-floating transmission device.

[0027] In actual operation, the air-floating transmission device of the utility model also includes a control mechanism (not shown), which is electrically connected to the driving mechanism and the air-floating force monitoring mechanism 30, respectively. Specifically, the control mechanism is electrically connected to the sensor component 32 of the air-floating force monitoring mechanism 30. During the transportation process of the plate-like element 10, if the air-floating driving force is continuously insufficient or unstable, causing the triggering sensor component 32 to issue a safety warning reminder for more than a preset time, the sensor group 32 will send a corresponding braking signal to the control mechanism, and the control mechanism will control the driving mechanism to stop running, so as to avoid the air-floating transmission device from continuing to operate abnormally when the operator fails to receive the warning reminder in time or fails to deal with the abnormal situation in time, causing safety hazards. In addition, the control mechanism can also be connected to the mobile display terminal for communication, and the control mechanism will send the warning signal to the mobile display terminal in real time for display, so as to promptly remind the operator of the abnormal situation of the air-floating transmission device.

[0028] In another embodiment, the air flotation transmission device further includes a control mechanism and an air source mechanism. The control mechanism is connected to the air source mechanism and the sensor component 32 respectively. When the sensor component 32 sends a warning signal exceeding a preset time, the sensor component 32 sends an enhancement signal to the control mechanism. The control mechanism controls the air source mechanism to enhance the airflow output per unit time, that is, to increase the driving force of the air flotation, thereby realizing automatic control, effectively improving work efficiency, and avoiding damage to the plate-like element 10 by timely eliminating abnormal conditions, thereby improving product quality.

[0029] In one embodiment, the preset time is set in a range of 6-10 seconds, but is not limited thereto. In actual operation, the preset time can be set according to the actual operation requirements of the air flotation transfer device.

[0030] Continue to refer Figure 1 In this embodiment, the roller assembly 31 includes a first roller 311 and a second roller 312, and the first roller 311 and the second roller 312 are arranged at intervals along the conveying direction F1 of the plate-like element 10, and the upper end of the first roller 311 and the upper end of the second roller 312 are located at the same height, and the sensor assembly 32 is arranged corresponding to the first roller 311. In actual operation, when conveying a large-area plate-like element 10, the number of air-floating plates 20 included in the air-floating transmission device is usually not less than two, because there is a gap between adjacent air-floating plates 20, and there is no upward high-pressure airflow at the gap, which makes it easier for the large-area plate-like element to be subjected to uneven force when passing through the gap. Therefore, in the air-floating transmission device of the utility model, the air-floating force monitoring mechanism 30 is arranged adjacent to the gap between adjacent air-floating plates 20. In one embodiment, the second roller 312 is located at the gap between adjacent air-floating plates 20, thereby improving the accuracy of the air-floating force monitoring mechanism 30 when monitoring the plate-like element 10. In this embodiment, the number, spacing, and placement of the air floating plates 20 can be adjusted according to the specific size of the plate-like elements 10 to be carried.

[0031] In actual operation, when the air buoyancy monitoring mechanism 30 is performing abnormal monitoring, in order to prevent the plate-like element 10 from touching the roller assembly 31 and causing damage, the material of the roller assembly 31 is preferably an elastic, wear-resistant or flexible material, such as resin, spandex, rubber, etc.

[0032] The air flotation monitoring mechanism and air flotation transmission device of the utility model can monitor in real time whether the distance between the plate-like element and the air flotation plate exceeds a preset safety height by arranging the air flotation monitoring mechanism on one side of the air flotation plate. When the plate-like element touches the upper end of the roller assembly included in the air flotation monitoring mechanism during the transportation process, causing the roller assembly to rotate, the sensor assembly included in the air flotation monitoring mechanism will detect the rotation and issue a warning reminder, so that the operator can deal with the abnormal situation in time and eliminate safety hazards, thereby avoiding scratches caused by the contact between the plate-like element and the air flotation plate during the transportation process.

[0033] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
