Example Embodiment

[0030] Reference Figure 1a with 1b , The suction cup includes a suction cup body 1. The suction cup body 1 has a cavity 12 with a circular cross section. The cavity 12 has a closed end surface and an open end surface. The open end surface forms an end surface for adsorbing objects, so The cavity 12 is provided with a tangential nozzle 11 on the wall surface, and further includes an annular partition 3 and a spacer block 2. The spacer blocks 2 are arranged at intervals on the bottom surface of the suction cup body 1, and the annular spacer The upper surface of 3 is fixedly connected to the outer edge of the bottom surface of the suction cup body 1 through a spacer block 2; the spacer block 2 covers a part of the area of ​​the annular partition 3, and the distance between the spacer block and the spacer block forms the suction cup body 1 A fixed flow channel between the outer edge of the bottom surface and the annular partition 3, the fixed flow channel communicates the internal ...

Abstract

A sucking disc comprises a sucking disc body (1), an annular separation plate (3), and cushion blocks (2). The sucking disc body (1) is internally provided with a chamber body (12) of which a transverse cross section is circular. A tangential nozzle (11) is disposed on a wall surface of the chamber body (12). An upper surface of the annular separation plate (3) is fixedly connected to the edge of a bottom surface of the sucking disc body (1) by mans of the cushion blocks (2). The cushion blocks (2) are disposed on the edge of the bottom surface of the sucking disc body (1) in a spaced manner. The number of the cushion blocks (2) is four, and the four cushion blocks (2) cover part of the area of the annular separation plate (3). Space between the cushion blocks (2) forms a fixed flow channel between the edge of the bottom surface of the sucking disc body (1) and the annular separation plate (3), and the fixed flow channel is in communication with the chamber body (12) and the peripheral environment. The sucking disc can suck a soft object with a rough surface, and consumes a little gas.

Description

technical field [0001] The invention relates to a suction cup. Background technique [0002] Mechanical clamping tools usually have two or more splints that can be opened and closed, and the clamping operation is realized by tightening the splints with force. However, mechanical gripping tools cannot grip soft sheet-shaped workpieces (such as slices of bread, sliced ​​tomatoes, etc.), and because of the wear and tear between mechanical parts, the daily maintenance workload is large. [0003] Rubber vacuum suction cups have the advantages of simple structure and easy maintenance, and are commonly used grabbing tools in food production lines. It is the most common way to use a vacuum pump or a vacuum generator to suck the inside of the suction cup into negative pressure. However, because there is a huge pressure difference between the negative pressure inside the vacuum chuck and the external atmospheric pressure, once there is a gap (even a small gap) at the edge of the suc...
