The round bottom plate comprises three round holes of vacuum pump joint (7), vacuum resistance tube joint (11) and vacuum tube joint (12) that are used for connecting vacuum pump, vacuum resistance tube and vacuum tube.    USE - A solar energy battery chip with nano thin film evaporation coat.    ADVANTAGE - The design of spherical evaporation sample frame and multi-dimension sample groove provides the uniformity of the metal film for solar battery sheet at different sizes. The structure provides high production efficiency.    DETAILED DESCRIPTION - A solar energy battery chip with nano thin film evaporation coat comprises spherical evaporation sample frame, cylindrical cavity (1) and size sample grooves (20). The cylindrical cavity is composed of circular top plate (14), cylindrical cavity and round bottom plate (13). The cylindrical cavity side includes air inlet hole (4) and observation window (3). The round bottom plate comprises three round holes of vacuum pump joint (7), vacuum resistance tube joint (11) and vacuum tube joint (12) that are respectively used for connecting vacuum pump, vacuum resistance tube and vacuum tube. The circular bottom plate includes the lower ball shell fixing frame (8), insulating table (9) and evaporation electrode (10). The ball shell fixing frame is provided with four symmetrical columns and a circular ring for fixing the lower ball shell (6). The evaporation electrode is used for hanging evaporating wire to pass through the insulating platform. The cylindrical cavity outside the wire is connected with the lower ball shell. The insulating platform and the evaporation electrode under the bottom of the spherical shell can pass through the lower ball circular hole. The hollow ball shell is divided into an upper ball shell (17) and the lower ball shell. The lower spherical shell is provided with a circular hole. The upper and lower ball shell is welded with the ball shell ring fixing belt (16). The upper and lower ball shell with ring fixed tightly assembled into complete ball shell. The ball shell and the circular top plate are fixedly connected to the lower spherical shell and circular bottom plate. The multi-dimension sample groove is a ball arc surface with square plane bottom surface. The samples groove of the bottom containing groove is used for fixing the solar battery sheet with one side of the clamp slot rotating around the edge and the solar cell plate pick-and-place. The rotary clamp slots that include a hoop are arranged parallel to each other. The sample groove of lower bottom surface includes a cylindrical array.
