Description

Multi-stage adsorption vacuum chuck

The technical field of the present invention relates to a suction cup structure, more specifically, a suction cup structure provided with a multi-stage suction portion on the circumference of the suction cup.

The vacuum sucker used in daily life, the way to remove the air in the sucker can be achieved by pressing the sucker to make it flat or manually operating the suction device on the sucker. This type of sucker must rely on a large flat deformation to make it almost full area contact. The suction surface is adhered to the suction surface by the material's anti-slip property and viscosity. Therefore, this type of suction cup can only be adsorbed on the flat, smooth glass surface, mirror surface, ceramic tile and other suction surfaces. It cannot be used for slightly rough surfaces. use. In addition, the adhesion of this type of suction cup to the suction surface gradually decreases from the center to the circumference. In other words, the adhesion of the circumference of the suction cup is the weakest. The pressure of the external air can easily break through the circumference and release the vacuum suction of the suction cup. Fall off. In addition, the area of this type of suction cup is small, so the suction area is small, and the suction force is weak. Because of the influence of factors such as changes in ambient temperature and humidity and the elastic recovery force of the suction cup, the load capacity of the suction cup is weak and easy. Fall off.

The purpose of this creation is to provide a vacuum chuck structure that enhances the adsorption force, the load-bearing capacity, can not fall off for a long time, and can even be used on an adsorption surface whose surface is not completely smooth and flat.

This invention creates a multi-stage suction vacuum sucker, including: a disc core and a part from the disc core The disk slope extending obliquely outwards on the circumference; the circular bottom of the disk slope is provided with a ring-shaped multi-stage adsorption section, the multi-stage adsorption section includes a plurality of concentrically surrounded adsorption stages, and several of the adsorption stages have height differences The height of the adsorption step closest to the center of the disk is the highest, and the height of the remaining adsorption steps sequentially decreases in the circumferential direction of the inclined portion of the disk.

Preferably, several of the adsorption steps have a width difference, the width of the adsorption step closest to the center of the disc is the smallest, and the widths of the remaining adsorption steps increase in order.

Preferably, the multi-stage adsorption portion is located at a position from the outer edge of the disc inclined portion to one-fifth of the outer portion.

The multi-stage suction section increases the adhesion of the vacuum suction cup's peripheral parts, and the external air pressure cannot easily break through the multi-stage suction parts of the circumferential parts, ensuring that the suction cup does not leak air.

The multi-stage adsorption section guarantees the degree of fit between the suction cup and the object. Each stage of the adsorption stage can form a closed sealed space. When the stage is attached to the object, if one stage of the adsorption stage fails due to protrusions or depressions, The adsorption stages of other stages can also play a sealing role, thus improving the adsorption ability of the sucker to objects with rough surfaces or defects such as micro-protrusions and pits.

In summary, the multi-stage adsorption section strengthens the fit between the suction cup and the adsorption surface, improves the adsorption force, the load-bearing capacity, can not fall off for a long time, and can be used on the adsorption surface whose surface is not completely smooth and flat.

In order to facilitate the explanation of the central idea expressed by the author in the above-mentioned new content column, specific embodiments are used to express it. Various objects in the embodiments are depicted in proportions, sizes, deformations, or displacements suitable for illustration, rather than in proportion to actual elements, which will be described together.

The first figure describes the composition of the vacuum suction device 10 and the vacuum suction cup 20 of the present invention. As is known, manually operating the vacuum suction device 10 can exhaust the air in the vacuum suction cup 20 and make the inside of the vacuum suction cup 20 vacuum. State while attracting a solid surface. The vacuum chuck 20 is made of a material with elastic deformation and recovery ability, and the material includes but is not limited to rubber, silicone rubber, and polyurethane.

In the first to fourth figures, the vacuum chuck 20 has a disc-shaped structure, and includes a disc core portion 21 and a disc inclined portion 22 extending obliquely outward from the circumference of the disc core portion 21. The vacuum chuck 20 is provided with an annular tooth-shaped multi-stage adsorption portion 30 on a circumferential bottom surface of the disc inclined portion 22, and the multi-stage adsorption portion 30 is located at a position one-fifth of the outer edge of the disc inclined portion 22. The multi-stage adsorption section 30 includes three adsorption stages 31, 32, and 33 concentrically surrounding, which are defined herein as a first adsorption stage 31, a second adsorption stage 32, and a third adsorption stage 33. The three adsorption stages have height differences. The third adsorption stage 33 closest to the disk core portion 21 is higher than the second adsorption stage 32, and the second adsorption stage 32 is higher than the first adsorption stage 33 closest to the circumference. Three adsorption stages have width The width of the first adsorption stage 31 is larger than that of the second adsorption stage 32, and the width of the second adsorption stage 32 is larger than the third adsorption stage 33.

As shown in the fifth to eight figures, the vacuum suction device 10 can be manually operated to exhaust the air in the vacuum chuck 20 to make the inside of the vacuum chuck 20 into a vacuum state. The vacuum chuck 20 is deformed slightly flat and the multi-stage adsorption part 30 adsorbs a Solid surface. The multi-adsorption adsorption part 30 is a stage adsorption. A first adsorption stage 31 is first adsorbed on a solid surface, and then a second adsorption stage 32 and a third adsorption stage 33 are sequentially followed.

Each stage of adsorption stages 31, 32, 33 can form a closed vacuum-tight space, and each stage of adsorption stages 31, 32, 33 adheres closely to the solid surface to maintain long-term adhesion and increase the circumference of the vacuum suction cup 20 The adhesion force of the vacuum chuck 20 ensures that no air leakage occurs in the vacuum chuck 20, which improves the problem of the weakest suction force on the circumference of the traditional vacuum chuck. Since the vacuum chuck 20 is not completely attached to the solid surface, but is attached to the solid surface by the multi-stage adsorption part 30, so in addition to the smooth and flat surface, if the solid surface is a slightly uneven surface that is not completely smooth, Also applicable. In addition, if one of the adsorption stages fails, the adsorption stages of the other stages can still function as a seal.

The way to release the vacuum suction state of the vacuum chuck 20 of this creation is to manually pull the convex portion 23 on the vacuum chuck 20 and apply a biasing force to pull upward on the vacuum chuck 20 to release the multi-stage adsorption by external force. The vacuum chuck 20 can be removed by attaching the portion 30 to the solid surface.
