Description

Technical Field

[0001] This utility model belongs to the field of suction cup technology, specifically relating to a novel suction cup structure. Background Technology

[0002] In the high-temperature process of solar cell manufacturing, the suction cups are prone to static electricity, causing debris to adhere to the suction cups. These debris require manual cleaning. If not cleaned, it can lead to microcracks or secondary debris, affecting the yield and breakage rate.

[0003] Although suction cup blowing functions are now widely used in high-temperature automated equipment for solar cells, significantly reducing debris on the suction cups, the additional blowing equipment increases the production cost of solar cells. Furthermore, due to the distance between the blowing equipment and the suction cups, some debris still cannot be removed, requiring manual cleaning. Utility Model Content

[0004] The purpose of this invention is to provide a novel suction cup structure to solve the problems mentioned in the background section. The novel suction cup structure provided by this invention has the characteristic of effectively removing debris from the suction cup by using close-range blowing.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a novel suction cup structure, comprising a suction cup body, a first air groove and a second air groove respectively provided on one side of the suction cup body, and a plurality of blowing holes communicating with the second air groove on the same side of the suction cup body, and a plurality of suction holes penetrating to the other side of the suction cup body provided inside the first air groove.

[0006] In order to generate negative pressure at the suction hole to suck up the silicon wafer, the connecting end of the first air groove is further connected to the vacuum generator through the first connecting pipe.

[0007] In order to blow air through the blowhole to remove debris from the adjacent suction cup body, the connecting end of the second air groove is further connected to the air storage tank through the second connecting pipe.

[0008] To increase the contact area with the silicon wafer and ensure the stability of the suction, the suction cup body is further provided with several extensions.

[0009] In this invention, the second air groove extends into the interior of the extension portion.

[0010] Furthermore, in this utility model, a second cover is connected to the second air groove, and a purge hole is provided on the second cover.

[0011] Furthermore, in this invention, a first cap is connected to the first air groove.

[0012] In order to increase the suction area of ​​the silicon wafer, make the silicon wafer more uniformly stressed, and ensure the stability of suction, a suction groove corresponding to the suction hole is provided on the other side of the suction cup body, and the suction groove extends to the extension.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features a blowhole on the suction cup body, located on the side opposite to the suction hole. After one suction action is completed, air can be blown through the blowhole to clean the suction surface of the adjacent suction cup body, removing the debris adsorbed thereon. Compared to the prior art method of removing debris through additional blowing equipment, this invention enables close-range blowing, ensuring not only the removal effect of debris but also reducing the production cost of solar cells.
