It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0031] like Figures 1 to 3 As shown, the technical solution of the embodiment of the present application is applied, a negative pressure component 10 and a bearing component 20, the negative pressure component 10 includes a first negative pressure structure 11 and a second negative pressure structure 12, the first negative pressure structure 11 is connected to the second negative pressure structure 12, the two together constitute an outlet air flow channel, the bearing component 20 includes a shell 21 and a bearing structure 22, the negative pressure component 10 is connected to the shell 21, the bearing structure 22 is movably connected to the shell 21, and the outlet air flow channel is arranged toward the bearing structure 22.

[0032] By applying the technical solution of the embodiment of the present application, the bearing assembly is moved so that the negative pressure assembly is located directly above the glass to be transported, and the air outlet channel ejects air in the horizontal direction, so that the pressure above the glass is reduced, and the glass rises in height under the action of the air pressure. Since the negative pressure assembly continues to discharge air, there is no contact between the glass and the negative pressure assembly. After the bearing structure is moved to directly below the glass, the negative pressure assembly stops discharging air, and the glass falls onto the bearing structure. The bearing structure is used to transport the glass to the next station. The technical solution of this embodiment effectively solves the problem of poor surface quality of the glass due to partial contact between the gripping device and the glass surface during the transportation of flat glass between adjacent stations in the prior art.

[0033] like Figure 1As shown, in the technical solution of this embodiment, the first negative pressure structure 11 has a groove 111, the second negative pressure structure 12 is arranged in the groove 111 and connected to the first negative pressure structure 11, and the outer wall of the second negative pressure structure 12 and the inner wall of the groove 111 together form an outlet air channel. This structure makes the outlet air channel annular, and the air is discharged evenly in all directions, ensuring that the glass is evenly stressed during the glass grabbing process and is not prone to sliding and falling off.

[0034] like Figure 1 As shown, in the technical solution of this embodiment, the groove 111 includes a connecting section 1111 and a guide section 1112. The connecting section 1111 is connected to the guide section 1112, and the diameter of the guide section 1112 decreases continuously in the direction from close to far away from the bearing structure 22. The second negative pressure structure 12 is connected to the connecting section 1111 by bolts. The second negative pressure structure 12 is partially located in the connecting section 1111. The guide section 1112 has an inclined surface with an inclination angle of 10° to 40°, so that the air is ejected in the horizontal direction. The high-speed flowing air reduces the air pressure above the glass, and the glass rises under the action of the air pressure. When the inclination angle is greater than 40°, the air outlet direction is toward the vertical direction, and the glass surface will receive the downward force of the air flow; when the inclination angle is less than 10°, the air outlet is more dispersed, the air pressure is lower, and the flow rate decreases. Due to the Bernoulli principle, the negative pressure generated is small, and it is not easy to adsorb the glass. As shown Figure 1 As shown, in the technical solution of this embodiment, the first negative pressure structure 11 has an inlet flow channel 112, the first end of the inlet flow channel 112 is connected to the air supply pipeline, and the second end of the inlet flow channel 112 is connected to the groove 111. The air supply pipeline provides clean compressed gas, which enters from the first end of the inlet flow channel 112 and flows into the groove 111 from the second end of the inlet flow channel 112. The groove 111 and the second negative pressure structure 12 have a predetermined spacing, and the compressed gas is distributed in an annular manner between the two and ejected at high speed in the horizontal direction under the action of the guide section 1112. Due to the Bernoulli principle, the compressed gas ejected at high speed reduces the air pressure above the glass, and the glass rises and separates from the lower station. In this embodiment, the inlet flow channel 112 has two air inlets, which are respectively arranged on the side and upper surface of the first negative pressure structure 11. The staff can select them according to needs to facilitate the connection of the air supply pipeline. When multiple negative pressure components 10 are used, the air inlet used by each negative pressure component 10 is appropriately selected to avoid interference from multiple air supply pipelines.

[0035] like Figure 1As shown, in the technical solution of this embodiment, the second negative pressure structure 12 has an annular groove 121, the annular groove 121 is connected to the inlet flow channel 112, and the outlet flow channel is connected to the annular groove 121. The gas ejected from the second end of the inlet flow channel 112 enters the annular groove 121, and the gas is evenly distributed along the annular groove 121. The side of the annular groove 121 close to the guide section 1112 is a guide surface, and the guide surface has a predetermined angle with the horizontal direction. The setting of the guide surface facilitates the air flow to the guide section 1112. The bottom side of the second negative pressure structure 12 is arranged in the vertical direction, and when the compressed gas is ejected, it will not interfere with the compressed gas, causing turbulence to affect the gas flow rate.

[0036] like Figure 1 As shown, in the technical solution of this embodiment, the housing 21 has a slide groove 211, and the bearing structure 22 is partially arranged in the slide groove 211, and the bearing structure 22 is movably connected to the slide groove 211. The slide groove 211 guides the movement of the bearing structure 22 and prevents the bearing structure 22 from moving in the vertical direction.

[0037] like Figure 2 and Figure 3 As shown, in the technical solution of this embodiment, the bearing structure 22 includes a bearing portion 221 and a guide portion 222, the guide portion 222 is connected to the bearing portion 221, and the height of the guide portion 222 decreases in the direction from approaching to away from the bearing portion 221. The setting of the guide portion 222 facilitates the staff to insert the bearing portion 221 into the slide groove 211, reduces the difficulty and time of operation, and improves work efficiency.

[0038] like Figures 1 to 3 As shown, in the technical solution of this embodiment, the distance between the bearing part 221 and the negative pressure assembly 10 is 4 to 7 times the thickness of the glass. When the glass is far away from the negative pressure assembly 10, the gas ejected by the negative pressure assembly 10 will not affect the air pressure above the glass, which is not conducive to grabbing the glass. After the negative pressure assembly 10 grabs the glass, after the bearing structure 22 is moved to the bottom of the glass, the negative pressure assembly 10 stops exhausting gas, and the glass falls onto the bearing structure 22. When the negative pressure assembly 10 is far away from the bearing structure 22, the glass falls a long distance, and the surface of the glass is easily damaged or broken. Therefore, the distance between the bearing part 221 and the negative pressure assembly 10 needs to be reasonably selected.

[0039] like Figure 2 and Figure 3 As shown, in the technical solution of this embodiment, the bearing assembly 20 further includes a first operating portion 23, which is connected to the housing 21 and is arranged away from the bearing structure 22. The first operating portion 23 is arranged on the housing 21, so that the staff can move the entire bearing assembly 20 and the negative pressure assembly 10 to the glass to be grasped.

[0040] like Figure 2 and Figure 3 As shown, in the technical solution of this embodiment, the bearing assembly 20 further includes a second operating portion 24, which is connected to the bearing portion 221 and is arranged away from the guide portion 222. The arrangement of the second operating portion 24 facilitates the staff to control the movement of the bearing structure 22 to carry and transfer the glass.

[0041] From the above, it can be known that the non-contact glass grabbing device (glass grabbing device) of the present invention solves the problem of not touching the glass in a strict sense, thereby grabbing the glass away from the tray and avoiding artificial contamination of the workpiece, especially after the glass has been processed and cannot be touched. In order to achieve the above purpose, the present application adopts the following technical solutions: handle (first operating part 23), shell 21, slide shovel (bearing structure 22) and vacuum suction cup (negative pressure component 10). Method of use: manually hold the device and place it on the glass, the vacuum suction cup covers a part of the glass, then press the switch button of the device, the vacuum suction cup will automatically open and start to suck the glass upwards, when the glass leaves the surface of the tray, the slide shovel starts to move forward until it slides under the glass. After the vacuum suction cup sucks the glass off the tray, it automatically closes and the glass is transferred to the slide shovel. At this time, the worker can hold the handle and leave and put it to the next process position. When the device is used for auxiliary transfer as designed, it will achieve the characteristics of increased speed, accuracy, convenience and no pollution.
