Embodiment Construction

[0014] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0015] like Figure 1~4 As shown, a vacuum adsorption table for solar cells includes a cover plate 1 and a base 2, the cover plate 1 is covered on the base 2, and there are at least two layers of vacuum pipeline cavities 2-1 on the base 2 from the inside to the outside. There are a plurality of vacuum adsorption holes 1-1 on the cover plate 1 corresponding to the vacuum pipeline cavity 2-1 of the base 2, arranged along the corresponding vacuum pipeline cavity 2-1, and vacuum adsorption Hole 1-1 communicates with corresponding vacuum pipeline cavity 2-1, and base 2 is also provided with a plurality of exhaust holes 2-2 for connecting vacuum equipment, and exhaust hole 2-2 and vacuum pipeline cavity Body 2-1 is in one-to-one correspondence and co...

Abstract

The invention discloses a solar cell vacuum adsorption table, which comprises a cover plate and a base, wherein the cover plate is covered on the base, and at least two layers of vacuum pipeline cavities are formed in the base from inside to outside; a plurality of vacuum adsorption holes are respectively formed in the cover plate corresponding to the vacuum pipeline cavities of the base and are communicated with the corresponding vacuum pipeline cavities, and a plurality of vent holes for connecting vacuumizing equipment are also formed in the base, corresponds to the vacuum pipeline cavities one by one and are communicated with the vacuum pipeline cavities. Through at least two layers of adsorption, a cell silicon chip is more firmly attached to the adsorption table, so that the phenomenon that the cell silicon chip is thrown away in the production process is avoided.

Description

technical field [0001] The invention relates to a vacuum adsorption table for solar cells, which belongs to the technical field of solar assembly equipment and is mainly used for screen printing table tops. Background technique [0002] At present, the adsorption device on the original screen printing table adopts a single vacuum pipeline method. If there is no silicon wafer or missing corners in the vacuum pipeline, the silicon wafer on the table will not be vacuum adsorbed, causing the silicon wafer to be sucked by the screen printing machine. When the turntable is thrown out, if the silicon wafer has a large displacement on the printing table, there will be a certain probability that several vacuum holes on the table will be exposed, which will cause the entire vacuum chamber to break the vacuum, so that the silicon wafer will not be on the table. Being attracted, it will leave the printing table. Contents of the invention [0003] The technical problem to be solved by...
