Vacuum transmission processing equipment and method

Abstract

The invention discloses vacuum transmission processing equipment and a vacuum transmission processing method. The equipment comprises a vacuum processing cavity, a workpiece inlet and outlet cavity and a plurality of transmission platforms, wherein the vacuum processing cavity comprises a processing region, a first waiting region and a second waiting region; the workpiece inlet and outlet cavity can be switched between an atmospheric state and a vacuum state; the transmission platforms are used for bearing workpieces to enable the workpieces to enter the workpiece inlet and outlet cavity from the atmospheric state, and enable the workpieces to enter the processing region from the workpiece inlet and outlet cavity through the first waiting region or the second waiting region so as to complete workpiece processing in the processing region, and enable the workpieces to move back to the workpiece inlet and outlet cavity from the processing region through the first waiting region or the second waiting region and then enable the workpieces to move back to the atmospheric environment from the workpiece inlet and outlet cavity; and each transmission platform is used for sequentially and continuously completing workpiece processing in the processing region. According to the invention, the effect of enabling the workpieces to continuously enter and exit the vacuum environment, and continuous processing on the workpieces are implemented only by designing one workpiece inlet and outlet cavity. Therefore, 100 percent of utilization on a processing medium is implemented, and processing efficiency is further greatly improved.

Description

technical field [0001] The invention relates to vacuum process technology, in particular to a vacuum transmission process equipment and a vacuum transmission process method realized by using the vacuum transmission process equipment. Background technique [0002] New energy is one of the five most decisive technological fields in the world's economic development in the 21st century, and solar energy is a clean, efficient and inexhaustible new energy. In the new century, governments of all countries regard the utilization of solar energy resources as an important content of the national sustainable development strategy. Photovoltaic power generation has many advantages such as safety, reliability, no noise, no pollution, less constraints, low failure rate, and easy maintenance. In recent years, with the rapid development of the international photovoltaic power generation industry, the supply of solar wafers is in short supply, so improving the production capacity of solar waf...
