Abstract

The invention discloses a vacuum transmission device comprising a transmission assembly, a first vacuum chamber, a second vacuum chamber and a vacuum generator. The transmission assembly consists of aconveyor belt and a conveying drive mechanism for driving the rotation of the conveyor belt. The first vacuum chamber is arranged below the conveying section of the conveyor belt and is in contact with the conveying section; and the first vacuum chamber and the second vacuum chamber are connected by a support assembly and are communicated by a connecting pipe. The vacuum generator and the secondvacuum chamber are communicated. Vacuum adsorption hole are formed in the surface, in contact with the first vacuum chamber, of the conveying section along the conveying direction and are communicatedwith the first vacuum chamber. Therefore, the negative pressure is uniform and stable and the battery sheet can be quickly and smoothly transmitted.

Description

technical field [0001] The invention relates to the field of automation equipment for manufacturing PERC high-efficiency batteries, in particular to a vacuum transmission device. Background technique [0002] In 2015, the photovoltaic leader plan was launched. Through this plan, the country guided the orderly upgrading of the photovoltaic industry. The industry responded positively and took advantage of the trend to accelerate the pace of high-efficiency battery technology from research and development to mass production. After the market crashes, the main high-efficiency cell technologies selected by the photovoltaic industry are: polycrystalline black silicon cell technology, N-type monocrystalline bifacial cell technology and P-type monocrystalline PERC cell technology. [0003] Compared with the conventional single crystal cell process, the PERC single crystal cell mainly adds three processes of rear passivation, rear SiNx film deposition and laser drilling. In recent y...
