A conveying assembly 3 includes a first driving assembly 31 and multiple rollers 32. The rollers 32 are installed at the roller holes 112, and the upper edge of the rollers 32 is higher than the upper surface of the support plate 11. A limiting assembly 4 includes a second driving assembly 41 and at least one pair of guide rods 42 installed on the left and right sides of the support plate 11. Specific descriptions of each component are as follows:

[0037] In this embodiment, the air-float positioning device further includes a mounting base plate 8, on which the air-float assembly 1, the conveying assembly 3, and the limiting assembly 4 are respectively mounted. A first groove is provided at the bottom of the support plate 11, communicating with multiple air holes 111. A cover 12 is fitted into the first groove, and the cover 12 and the support plate 11 enclose a first gas channel 21. The depth of the first groove is equal to the height of the cover 12. A gas supply fixing component 13 covers the assembly connecting the support plate 11 and the cover 12, and the gas supply fixing component 13 and the assembly enclose a second gas channel 22. The support plate 11, the cover 12, and the gas supply fixing component 13 are detachably connected, for example, by bolts. The gas generated by the gas generator is used to suspend the workpiece above the air-float positioning device. In some other embodiments, the gas generated by the gas generator is an electrostatic eliminator gas, achieving the effect of eliminating static electricity from the workpiece.

[0038] The technical effects that this air-float positioning device can achieve are as follows:

[0039] The workpiece is driven into the air-floating positioning device by the roller 32. The gas generated by the gas generator is evenly distributed at each air hole 111 through the first gas channel 21 and the second gas channel 22 to achieve the stability of the workpiece's suspension height. The position of the workpiece is corrected by the limiting component 4 to complete the positioning of the workpiece so that the robotic arm can pick up the positioned workpiece on the air-floating positioning device.

[0040] See also Figures 1-13 In this embodiment, the first gas channel 21 is distributed longitudinally along the tray 11, and the second gas channel 22 is distributed laterally along the tray 11.

[0041] In this embodiment, the roller 32 drives the workpiece into the air-float positioning device in a longitudinal direction, and the first gas channel 21 and the second gas channel 22 are intersected in a longitudinal and transverse manner to achieve a more uniform air pressure distribution in the air-float positioning device.

[0042] Furthermore, the conveying assembly 3 also includes a drive shaft 33 and a plurality of rollers 32 shafts 34. The rollers 32 are disposed on the rollers 32 shafts 34, and the plurality of rollers 32 shafts 34 are arranged at equal intervals below the air flotation assembly 1. The drive shaft 33 is connected to the rollers 32 shafts 34 and the first drive assembly 31 respectively.

[0043] Specifically, multiple rollers 32 are equally spaced on a roller shaft 34. A drive shaft 33 is installed on the same side of all roller shafts 34. A first magnetic wheel 331 is provided on the drive shaft 33. A second magnetic wheel 341 corresponding to the first magnetic wheel 331 is provided at the end of the roller shaft 34. The first drive assembly 31 drives the drive shaft 33 to rotate. During the rotation of the drive shaft 33, the first magnetic wheel 331 drives the second magnetic wheel 341 to rotate, thereby driving the roller shaft 34 to rotate.

[0044] Furthermore, it also includes a lifting device 5, which is connected to the air flotation assembly 1.

[0045] Specifically, the lifting device 5 is used to drive the air flotation component 1 to move up and down. In this embodiment, when the support plate 11 is at the lower end of the vertical movement stroke of the lifting device 5, the upper edge of the roller 32 is higher than the upper surface of the support plate 11. When the support plate 11 is at the upper end of the vertical movement stroke of the lifting device 5, the upper edge of the roller 32 is lower than the upper surface of the support plate 11, or the upper edge of the roller 32 is level with the upper surface of the support plate 11.

[0046] Furthermore, the tray 11 is provided with a plurality of notches 113, and the guide rods 42 are distributed at the notches 113.

[0047] Specifically, notches 113 are distributed from the edge of the support plate 11 towards the central axis, and the second drive assembly 41 is used to drive the guide rod 42 to move within the range of notches 113. By installing notches 113 from the edge of the support plate 11 inward, the range of movement of the guide rod 42 is increased, which can accommodate workpieces of various sizes and achieves the effect of high adaptability of the air-floating positioning device.

[0048] Furthermore, the limiting component 4 also includes a conveyor belt 43, a track 44, and a connector 45. The conveyor belt 43 is connected to the second drive component 41 and the connector 45 respectively. The guide rod 42 is connected to the track 44 and the connector 45 respectively. The track 44 is installed below the air flotation component 1.

[0049] Specifically, the first drive assembly 31 and the second drive assembly 41 are respectively fixed to the bottom of the mounting base 8, and multiple tracks 44 are installed on the top of the mounting base 8. The mounting base 8 has an elongated opening through which a connector 45 passes. The bottom end of the connector 45 is connected to the conveyor belt 43, and the top end of the connector 45 is connected to a fixing member. A guide rod 42 on the same side is connected to a fixing member. The bottom of the fixing member has multiple sliders and corresponding tracks 44. The sliders are sliding components on the tracks 44. The conveyor belt 43 is fitted onto the second drive assembly 41, and the second drive assembly 41 drives the drive belt, connector 45, fixing member, sliders, and guide rod 42 to move.

[0050] Furthermore, it also includes a side guard assembly 6, which is distributed around the perimeter of the tray 11.

[0051] Furthermore, the edge-blocking assembly 6 is provided with a guide portion 62.

[0052] Specifically, the air flotation positioning device is equipped with side guard assemblies 6 on both the left and right sides. The height of the side guard assembly 6 is greater than the thickness of the workpiece. In this embodiment, the top of the side guard assembly 6 is flush with the top of the guide rod 42. The baffle assembly is equipped with a guide part 62 on the feeding side of the air flotation positioning device. The main body 61 of the baffle assembly has a flat structure. On the side of the baffle assembly close to the air flotation assembly 1, the surface of the guide part 62 forms an angle greater than 180° with the surface of the main body 61, and a rounded corner transition is used at the connection between the guide part 62 and the main body 61.

[0053] Furthermore, a buffer is provided at the end of the guide rod 42.

[0054] Specifically, the buffer is made of elastic material and is used to absorb kinetic energy, suppress vibration, and protect the surface when the guide rod 42 contacts the workpiece, so as to avoid scratches on the workpiece caused by rigid collision.

[0055] Furthermore, multiple sensing modules 7 are provided below the air flotation component 1.

[0056] Specifically, the sensing module 7 includes a photoelectric sensor, which is installed below the air flotation assembly 1 and located on the feeding side of the air flotation positioning device, for monitoring the feeding of the workpiece.
