Description

Vacuum chuck

Technical Field

The utility model particularly relates to a centre gripping field of breakable thin slice part specifically is to relate to a vacuum chuck.

Background

The surface of a common vacuum chuck is generally provided with a plurality of communicated grooves, and one side of the vacuum chuck is provided with an air exhaust hole communicated with the grooves and connected with a vacuum pump. When the vacuum chuck is used, the non-metal workpiece is placed on the vacuum chuck, the groove on the vacuum chuck forms a sealed cavity, and the vacuum pump is used for vacuumizing the cavity, so that the non-metal workpiece is firmly adsorbed on the surface of the vacuum chuck.

However, when a glass sheet product with a smooth surface is sucked for placing, the air pressure in the sucking disc is gradually recovered, when the balance is reached, and the sucking disc moves upwards, certain glass sheets are still attached to the sucking disc due to the fact that the surface of the glass sheet is very smooth, so that when the sucking disc continues to lift, the glass sheets drop due to self gravity, the glass is broken, and the glass processing efficiency is not high.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above problem, provide a vacuum chuck, when making this sucking disc place the work piece, can make stable, the safe placing in of work piece wait to put the point, can not cause the phenomenon appearance that glass damaged.

In order to achieve the above object, the utility model adopts the technical scheme that the vacuum chuck is provided with:

the sucker seat is downwards provided with an opening along the length direction, a movably connected piston push plate is arranged in the opening in a sealing mode, and a through hole is formed in the piston push plate in a penetrating mode along the length direction;

the guide post is provided with a first air duct which is in conduction connection with a first air pipe joint, the first air duct extends into the upper end of the sucker seat, enters the through hole of the piston push plate, is hermetically arranged on the piston push plate and is arranged in a sliding manner with the piston push plate; and

the sucker body is arranged on the sucker seat and forms a suction cavity with the sucker seat;

and a second air duct capable of driving the piston push plate to move downwards along the length direction is arranged between the piston push plate and the sucker seat, the air duct is connected with a second air pipe joint, and a reset spring capable of enabling the piston push plate to return to the initial position is arranged.

Further, wherein,

an annular groove is arranged at the sealing connection part of the piston push plate and the opening of the sucker seat, so that the sealing ring is arranged on the annular groove and is sealed with the sucker seat.

Further, wherein,

the piston push plate extends along the length direction to form a connecting part, the connecting part is provided with external threads, and the piston push plate is connected with push blocks of different types through the external threads.

Further, wherein,

the outer wall of the guide pillar is sleeved with a fixing ring, and the fixing ring is provided with a connecting port for connecting the second air duct and the second air duct connector.

Further, wherein,

the sucker body is provided with a fixed part in threaded connection with the sucker seat and an adsorption part for sucking a workpiece.

Compared with the prior art, the utility model, beneficial effect does: after the fragile workpiece is placed and before the sucker is lifted, the fragile workpiece is separated from the sucker body through the piston push plate, so that the fragile workpiece is prevented from being still attached to the sucker when lifted, and the fragile workpiece is prevented from being damaged; other advantages of the present invention will be further explained in the detailed description of the invention.

Detailed Description

In order to make the technical solution of the present invention better understood, the present invention is described in detail below with reference to the accompanying drawings, and the description of the present invention is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention.

Referring to fig. 1 and 2, the present embodiment provides a vacuum chuck, which includes: the sucking disc seat 10, the guide post 50 and the sucking disc body 20 are different from the sucking disc of the prior art in that the sucking disc seat 10 is provided with an opening 101 downwards along the length direction, a movably connected piston push plate 11 is arranged in the opening 101 in a sealing manner, the piston push plate 11 is provided with a through hole 111 through along the length direction, so that the first air duct 40 communicated with the first air pipe joint 41 extends into the through hole 111 of the piston push plate 11 from the upper end of the sucking disc seat 10, can extend out of the through hole 111 or be arranged in the through hole 111, is arranged in a sealing manner with the piston push plate 11, and enables the piston push plate 11 to slide on the first air duct 40.
