Description

Technical Field

[0001] The utility model relates to a universal vacuum suction cup, in particular to a universal vacuum suction cup with a small volume and convenient adjustment of the adsorption area. Background Art

[0002] In the industrial production line, sheet materials such as labels are mostly picked up by vacuum adsorption using a suction cup with an array of suction holes. Due to the wide variety of label shapes and specifications, small vacuum suction cups are required on some precision equipment. However, the small vacuum suction cups currently available on the market can only be picked up by directly replacing the vacuum suction cup with the adsorption shape corresponding to the label shape. Therefore, each time the label specification is changed, the corresponding vacuum suction cup needs to be manually replaced, which brings inconvenience. Utility Model Content

[0003] The utility model aims to provide a universal vacuum suction cup, which can simply and conveniently adjust the size of the adsorption area of ​​the vacuum suction cup, and has a simple structure and a small size.

[0004] The technical solution of the present utility model is based on a vacuum seat, a vacuum joint, and an air hole regulator, and is characterized in that the bottom of the vacuum seat is alternately arrayed with threaded holes and suction holes to form a vacuum adsorption area, an adjacent threaded hole and a suction hole form a group of adsorption units, and each group of adsorption units is respectively provided with an air hole regulator in the cavity of the vacuum seat, and the air hole regulator is composed of a sealing ring, a connecting piece, and a hexagonal screw. The sealing ring is fixedly mounted on the left side of the bottom of the connecting piece, and the hexagonal screw can be rotatably mounted on the right side of the bottom of the connecting piece. A notch is provided in the middle of the left end of the connecting piece, and a protrusion is provided in the middle of the right end of the connecting piece. The air hole regulator is sequentially arrayed on the threaded hole at the bottom of the vacuum seat through the hexagonal screw, and the sealing ring of the air hole regulator is vertically opposite to the corresponding suction hole up and down, and the protrusions of the two adjacent connecting pieces are snapped into the notch.

[0005] The forward and reverse rotation of the hexagonal screw of the air hole regulator of the utility model can drive the sealing ring to move up and down through the connecting piece, thereby opening or closing the corresponding suction hole, thereby adjusting the size of the vacuum adsorption area. The distance that the hexagonal screw drives the connecting piece to move up and down is not greater than the thickness of the connecting piece.

[0006] The working principle of the utility model is to use a hexagonal screwdriver to insert one by one into the threaded hole at the bottom of the vacuum seat and turn the hexagonal screw forward and backward to drive the connecting piece and the sealing ring to move up and down, so that the sealing ring can open or close the corresponding suction hole, thereby achieving convenient and quick adjustment of the size of the suction area of ​​the vacuum suction cup.

[0007] The utility model discloses the advantage is simple structure, low in manufacturing cost, small, stable and reliable work, it can adjust the adsorption area size of vacuum chuck according to various label specification size flexibly. BRIEF DESCRIPTION OF DRAWINGS

[0014] According to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the utility model is based on the vacuum seat 1, the vacuum joint 2, and the pore regulator 5. The characteristic is that the bottom of the vacuum seat 1 is alternately arrayed with threaded holes 3 and suction holes 4 to form a vacuum adsorption area. The threaded holes 3 and suction holes 4 are through holes. The suction hole 4 is connected to the vacuum joint 2 through the inner cavity of the vacuum base 1. An adjacent threaded hole and a suction hole constitute a group of adsorption units. Each group of adsorption units is respectively provided with an pore regulator 5 in the cavity of the vacuum seat 1. The pore regulator 5 is composed of a sealing ring 5.2, a connecting piece 5.1, and a hexagonal screw 5.3. The hexagonal screw 5.3 is a hexagonal screw with an external thread. The sealing ring 5.2 is fixedly mounted on the left side of the bottom of the connecting piece 5.1, and the hexagonal screw 5.3 is rotatably mounted on the right side of the bottom of the connecting piece 5.1. A notch is provided in the middle of the left end of the connecting piece 5.1, and a protrusion is provided in the middle of the right end of the connecting piece 5.1. The pore adjusters 5 are sequentially mounted in an array on the threaded holes at the bottom of the vacuum seat via the hexagonal screws 5.3. The sealing rings of the pore adjusters 5 are vertically opposite to the corresponding suction holes at the top and bottom, and the protrusions of the two adjacent connecting pieces are snapped into the notches. In this way, the pore adjusters 5 are sequentially arrayed and installed in series from left to right as a group, and then the pore adjusters 5 are arranged in series in a longitudinal manner to cover the adsorption area. The forward and reverse rotation of the hexagonal screw of the pore adjuster 5 can drive the sealing ring 5.2 up and down through the connecting piece 5.1 to open or close the corresponding suction hole, thereby adjusting the size of the vacuum adsorption area. The distance that the hexagonal screw 5.3 drives the connecting piece 5.1 up and down is no greater than the thickness of the connecting piece 5.1.
