FIG. 1 is a schematic structural diagram of a circular vacuum chuck according to an embodiment of the present invention; FIG. 2 is a schematic diagram of the internal structure of a circular vacuum chuck according to an embodiment of the present invention. As shown in the figure, the circular vacuum chuck comprises a chuck body 1, and chuck bottoms 2 are arranged at two ends of the chuck body 1. The sucker bottom 2 is provided with a screw 8, the sucker bottom 2 is provided with a fixing hole matched with the screw 8, and the screw 8 is inserted into the fixing hole. The sucker bottom 2 is fixed on the sucker body 1 through a screw 8. The outer surface of the sucker bottom 2 is provided with a buffer layer 9. The buffer layer 9 is a polyurethane layer, and polyurethane blocks distributed in a circumferential array around the axis of the sucker bottom 2 are arranged on the polyurethane layer. Buffer layer 9 adopts the polyurethane material, can effectively prevent glass product's slip and the vibrations that produce in the course of working from shaking broken glass product.

A sucker ring 3 with sealing function is arranged outside the sucker bottom 2. The sucking disc ring 3 is of a horn-shaped structure, the edge of the sucking disc ring 3 protrudes out of the sucking disc bottom 2 to play a supporting role, and the sucking disc ring 3 forms a negative pressure cavity under the extrusion effect of a glass product, so that the sucking disc is more stable during adsorption. The sucker ring 3 can be a rubber ring, so that the sealing effect is improved, and the adsorption capacity with glass products is improved.

The suction structure is arranged inside the suction cup body 1. The air suction structure comprises a longitudinal communicating pipe 4, a transverse communicating pipe 5 and an air suction pipe 6, wherein an air port of the longitudinal communicating pipe 4 is positioned on the sucking disc bottom 2, the transverse communicating pipe 5 is communicated with the longitudinal communicating pipe 4, and the transverse communicating pipe 5 is connected with an air suction port 7 through the air suction pipe 6. The sucker body 1 is provided with a convex column 10 which seals the sucker ring 3 and the sucker bottom 2, and the sucker ring 3 and the sucker bottom 2 are tightly wrapped together by the convex column 10, so that air leakage is not easy to occur when the sucker is used for adsorption.

The suction port 7 is arranged in the middle of the side wall of the suction cup body 1, two suction ports 7 are arranged on the suction cup body 1, and the two suction ports 7 are respectively communicated with the suction cup bottoms 2 at the two ends of the suction cup body 1 through the transverse communicating pipe 5 and the longitudinal communicating pipe 4. The air port is located in the center of the suction cup bottom 2. When the suction pipe is used for sucking air, the air enters from the air port, flows into the transverse communicating pipe 5 through the longitudinal communicating pipe 4, flows through the suction pipe 6 through the transverse communicating pipe 5 and flows out from the air suction port 7, so that vacuum is formed between the suction disc and a glass product, and the suction disc and the glass product are firmly adsorbed together.

When the glass product sucking device is used, the air suction port 7 is connected with the air nozzle connector to suck air in vacuum, one end of the sucking disc is tightly adsorbed on a glass product through the air suction structure, the other end of the sucking disc is adsorbed on a table top, and then the glass product is processed.

Therefore, the circular vacuum chuck adopting the structure can solve the problems that the existing glass product is easy to break and can not be chamfered on two sides during processing.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: modifications and equivalents may be made to the utility model without departing from the spirit and scope of the utility model.
