Description

Suction cup structure

This creation is about a suction cup structure, especially a suction cup structure suitable for adsorbing flat glass absorbing materials.

Please refer to FIG. 4 to FIG. 6, which are a first perspective perspective view, a second perspective perspective view and a side view of a conventional sucker structure, respectively. The figure shows a conventional suction cup structure 91, which is an integrated gel suction cup, which is provided with a first through hole 911 and a second through hole 912, the first through hole 911 is directly in contact with the sorbent, can be used for Move or transport the sorbent. The second through hole 912 is connected to a vacuum source, and a negative pressure is formed inside the suction cup structure 91 by a vacuum device. At this time, the external atmospheric pressure will press against the attracted object, and an attractive force is formed between the suction cup structure 91 and the attracted object. , So that the attracted matter is stably adsorbed and attached to the suction cup structure 91.

However, with the advancement of materials science and process technology, many sorbents are getting thinner and thinner, and the requirements on the surface of the sorbents are becoming more and more fine. Therefore, if the above-mentioned traditional integrated silicone or rubber suction cup is used for the adsorption operation, In addition to the opportunity to cause the phenomenon of depression of the suction cup surface, it is easier to produce obvious suction marks between the suction objects and even cause the suction objects to break.

Because of this, the creative person is based on the spirit of active creation, and urgently thinks of a sucker structure that can solve the above problems. After several research experiments, the creation is completed.

The main purpose of this creation is to provide a suction cup structure. The arrangement of the suction unit made of ceramic material helps to reduce the incidence of scratches on the surface of the adsorbate, while avoiding obvious marks and When the adsorption force is too large, it will cause the absorbing matter to break.

In order to achieve the above purpose, the suction cup structure of this creation includes a suction cup body and a suction unit. The suction cup body is provided with a first through hole and a second through hole, and has an accommodating space. The suction unit is arranged on the suction cup body and filled. Fill the first through hole. It is characterized in that the adsorption unit is a ceramic element with numerous capillary holes.

Through the above design, the creation can form a negative pressure state in the accommodating space through the second through hole, and then adsorb the adsorbate to the adsorption unit using atmospheric pressure, and the adsorption unit is made of ceramic elements It has the characteristics of hardness and easy processing, and it is not easy to cause depressions or marks on the adsorbed part of the adsorbate, so it can be easily adsorbed and unloaded, which is convenient for the user to move the adsorbate and make the adsorbate The appearance of the objects remains the same, effectively increasing the overall production capacity and improving the yield.

The second through hole can be connected to a vacuum source. In this way, the creation can directly use the vacuum source formed by a vacuum device to absorb the gas in the accommodating space to form a negative pressure state, thereby generating an adsorption force.

The pore size of the capillary holes may be 2 to 3 microns. In this way, the above-mentioned aperture size can evenly distribute the strong negative pressure suction force of the vacuum source on the suction unit, so that the adsorbate can be adsorbed smoothly without causing the problem of local suction force being too strong.

The thickness of the above absorbing unit can be 0.3~0.5 cm. In this way, the above-mentioned thickness dimension can provide sufficient structural strength, so that the suction unit will not be deformed or broken due to the strong negative pressure suction of the vacuum source, and the excessively thick thickness dimension will also reduce the adsorption force. The creation department is preferably based on the above thickness.

The first through hole may be a circular through hole; the absorbing unit may be a circular absorbing unit. In this way, the first through hole can be assembled to match the appearance of the suction unit, and the round suction unit is not prone to stress concentration points, so the edge damage of the suction unit can be effectively avoided and the service life can be extended.

The above summary and the following detailed description are of exemplary nature in order to further illustrate the scope of patent applications for this creation. The other purposes and advantages of this creation will be explained in the subsequent description and illustration.

Please refer to FIGS. 1 to 3, which are respectively an exploded view at a first perspective, an exploded view at a second perspective, and a cross-sectional view of a suction cup structure of a preferred embodiment. The figure shows a chuck structure 1, which is used to adsorb glass, panels, wafers and other structures in this embodiment, including a chuck body 2 and a suction unit 3.

The suction cup body 2 is the outer shell of the creative suction cup structure 1 and is generally made of plastic material. The first through hole 21 and the second through hole 22 are opened, and a receiving space 23 is provided. In this embodiment, the first The through hole 21 is a circular through hole for assembling the suction unit 3; and the second through hole 22 is used for connecting a vacuum source, which is formed by a vacuum device and is used for sucking The gas in the space 23 is put into a negative pressure state. At this time, the external atmospheric pressure will press against the absorbing substance, and an adsorption force is formed between the absorbing unit 3 and the absorbing substance, so that the absorbing substance is stably adsorbed and attached. Close to the suction unit 3.

Among them, the main technical feature of this creation is that the suction unit 3 is a ceramic element with numerous capillary holes 31. The suction unit 3 is set on the suction cup body 2 and completely fills the first through hole 21, so that Gas can only pass through the capillary holes 31.

In this embodiment, the pore diameter of the capillary hole 31 is between 2 and 3 microns, so that the strong negative pressure suction force of the vacuum source is evenly distributed on the adsorption unit 3, so that the adsorbate can be smoothly adsorbed, and There is no problem of excessive local suction. The thickness of the suction unit 3 is between 0.3 and 0.5 cm, so as to provide sufficient structural strength so that the suction unit 3 will not be deformed or broken due to the strong negative pressure suction of the vacuum source. The thickness will also reduce the adsorption force, so this creation is preferably based on the above-mentioned aperture and thickness, but not limited to this, other size designs can also be used.

Among them, the suction unit 3 made of ceramic material has a hard texture and is easy to process, which helps to reduce the incidence of scratches on the surface of the adsorbate, and can avoid obvious marks on the adsorbate and cause suction when the suction force is too large Occurrence of broken objects.

Furthermore, in this embodiment, the first through hole 21 is a circular through hole, and the suction unit 3 is also a circular suction unit that can match the first through hole 21. In this way, the suction unit 3 can completely close the first through hole 21, and the round suction unit 3 is not prone to stress concentration points, so the edge damage of the suction unit 3 can be effectively avoided, and the service life can be extended.

The above-mentioned embodiments are only examples for the convenience of description, and the scope of the rights claimed in this creation should be subject to the scope of the patent application, and not limited to the above-mentioned embodiments.
