Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The embodiment discloses a vacuum chuck, as shown in fig. 1-4, including a chuck cavity 1, a chuck side wall 15 and a chuck skirt 2, a plurality of strengthening ribs 3 are provided in the chuck cavity 1, the strengthening ribs 3 are circumferentially distributed in the chuck cavity 1, and the strength of the chuck cavity 1 at the vent hole 13 and the mounting hole 14 can be strengthened through the strengthening ribs 3, so that the chuck is more firm and reliable after being mounted on equipment.
3-4, a pressing ring piece 6 and a support column 4 are arranged on the suction cup skirt edge 2, a pressing rod 5 is hinged to the support column 4, one end of the pressing rod 5 is hinged to the pressing ring piece 6, an arc-shaped tooth piece A501 is arranged at the other end of the pressing rod 5, a fixing column 8 is fixedly arranged on the suction cup side wall 15, a linkage rod 7 is hinged to the fixing column 8, an arc-shaped tooth piece B701 is arranged at one end of the linkage rod 7, a notch 702 is formed in the other end of the linkage rod, a telescopic rod 9 is movably connected in the notch 702, the telescopic rod 9 penetrates through the suction cup side wall 15 and extends into the suction cup cavity 1, an inner blocking piece 10 and an outer blocking piece 11 are respectively arranged on two sides, located on the suction cup side wall 15, of the telescopic rod 9, and a tension spring 12 is abutted between the inner blocking piece 10 and the suction cup side wall 15.
The specific motion of the above structure is described in detail as follows: after air suction is started, negative pressure is generated in the suction disc cavity 1, a small amount of external air enters the suction disc cavity 1 from the hole in the telescopic rod 9, and due to the fact that the air suction amount is large, the external air pushes the outer blocking piece 11 to be attached to the side wall 15 of the suction disc, the hole is blocked through the outer blocking piece 11 and the rubber sealing ring on the outer blocking piece, and the suction disc cavity 1 is sealed; the movement of the outer separation blade 11 can drive the telescopic rod 9 to move synchronously, and because the telescopic rod 9 has one end movably connected with the notch 702, the movement of the telescopic rod 9 can drive the linkage rod 7 to deflect, and the end part of the telescopic rod 9 can also slide in the notch 702 to a certain extent, wherein the deflection of the linkage rod 7 is an arc-shaped movement track taking a hinge point of the fixed column 8 as a center, and the movement of the telescopic rod 9 and the deflection of the linkage rod 7 can be adapted to each other by the aid of the notch 702. When the gangbar 7 deflects, the arc-shaped tooth piece B701 can also deflect synchronously, so that the arc-shaped tooth piece A501 meshed with the gangbar is driven to rotate, the pressing rod 5 can be driven to deflect by taking the hinge point of the supporting column 4 as the center, one end of the pressing rod 5 hinged on the pressing ring piece 6 is pressed against the sucker skirt 2, the situation of edge warping is prevented, the pressing ring piece 6 can slightly stretch out a part of the outer side of the sucker skirt 2, the sucker skirt 2 is made of soft rubber material, in the process of extruding the sucker skirt, the rubber material can possibly deform to protrude towards the edge, and the pressing ring piece 6 slightly stretches out of the outer side to press the deformed protruding part. After deflation, the negative pressure in the suction cup cavity 1 disappears, the telescopic rod 9 is reset under the action of the inner blocking piece 10 and the tension spring 12 on the telescopic rod, and the pressing ring piece 6 does not press the suction cup skirt 2 any more.
Furthermore, four supporting columns 4, four fixing columns 8, four pressing rods 5, four pressing ring pieces 6, four linkage rods 7 and four telescopic rods 9 are arranged respectively, and the four pressing ring pieces 6 are mutually spliced to form an annular shape and are abutted to the surface of the suction cup skirt 2.
Furthermore, the sucker cavity 1 is provided with a vent hole 13 and a mounting hole 14, and the vent hole 13 and the mounting hole are connected with an external air suction assembly.
The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
