[0032] Embodiment one

[0033] As Figures 1-3As shown, the embodiment provides a lens suction device, which comprises a tray 1 for placing lenses 44 and a suction plate 2 for sucking the lenses 44, the suction plate 2 comprises an upper plate body 20 and a lower plate body 21 assembled on the bottom surface of the upper plate body 20; a negative pressure cavity 22 is formed between the upper plate body 20 and the lower plate body 21, the top end surface of the upper plate body 20 is provided with a handpiece 23, a gas valve switch 24 and a gas hole 25, one end of the gas valve switch 24 is connected to an external vacuum pump, and the other end is in communication connection with the negative pressure cavity 22 through the gas hole 25; the lower plate body 21 is installed with a plurality of suction nozzles 26 in communication connection with the negative pressure cavity 22.

[0034] The lens suction device provided by the embodiment can cover the suction plate 2 and the tray 1 by operating personnel grabbing the handpiece 23, so that each suction nozzle 26 can abut against the lens 44 in the corresponding accommodation cavity 10, and then the button on the gas valve switch 24 is pressed to form a negative pressure airflow in the negative pressure cavity 22, under the action of the negative pressure airflow, the lens 44 is sucked onto the suction nozzle 26, at this time, the button of the gas valve switch 24 is released, the suction plate 2 carrying the lens 44 is moved above the target work station, and the button of the gas valve switch 24 is pressed again to release the negative pressure cavity 22, so that the lens 44 falls to the target work station under the action of its own gravity. The lens suction device effectively solves the problem that the lens 44 is easily damaged when the lens 44 is gripped by a mechanical hand in the prior art by the way of sucking and carrying the lens 44 by the suction nozzle 26. In addition, the lens suction device can suck a plurality of lenses 44 at one time by the matched structure of the suction device and the tray 1, thereby improving the carrying efficiency of the lens suction device.

[0035] In the embodiment, as shown, Figure 2 The handpiece 23 extends from the center of the upper plate body 20 to the edge direction, an empty hole 231 is formed near the end of the handpiece 23, the gas valve switch 24 is arranged on the lower plate body 21 below the empty hole 231, and the button on the gas valve switch 24 is arranged opposite to the empty hole 231, that is, the empty hole 231 is arranged to facilitate the pressing operation of the button of the gas valve switch 24 by the fingers of the operating personnel. One end of the gas valve switch 24 is connected to the gas hole 25 through a gas guide pipe, and the other end is connected to the external vacuum pump through a gas guide pipe, so that a negative pressure system is formed between the gas valve switch 24 and the negative pressure cavity 22.

[0036] Specifically, as shown, Figure 1As shown, the side edge of the lower disc body 21 is provided with a first limiting part 27, and the first limiting part 27 is provided with a limiting column 271. The outer side edge of the tray 1 is provided with a first limiting groove 11. The number of the first limiting part 27, the limiting column 271 and the first limiting groove 11 can be set according to the shape of the suction tool and the tray 1. In this embodiment, the suction tool and the tray 1 are circular in shape. The tray 1 is provided with a plurality of annular accommodation cavities 10. The bottom of the lower disc body 21 is provided with a plurality of annular suction nozzles 26. The first limiting part 27, the limiting column 271 and the first limiting groove 11 are respectively provided with two. When the suction tool is closed on the tray 1, the limiting column 271 is clamped into the first limiting groove 11.

In this embodiment, the lower disc body 21 surrounding the plurality of suction nozzles 26 is provided with a sealing groove, and a sealing strip is arranged in the sealing groove. The upper disc body 20 and the lower disc body 21 are threadedly locked between them by setting a plurality of screws on the edge. At the same time, the sealing strip deforms and tightly fits between the upper disc body 20 and the lower disc body 21 when the screw is locked, thereby relatively packaging the negative pressure cavity 22.
