In the process of manufacturing transistor, a lot of girls are engaged in its work. Especially in mount operation, almost all the works depend on their highly skilled handlings. It would, therefore, be quite efficient and economical if we could adopt automatic operation instead of their handlings.
To materialize this idea, however, there are much trouble. The structure of diminutive size and delicate articles made it difficult to handle mechanically. Besides we can expect no accurate dimension in the pitch of stem leads, for they are set by sintered glass. Under such difficult condition, we started the job to meet much trouble as was expected. But we are successful in mechanizing the works last year. As a result, we can save the operaters six or eight for two shifts without employing skilled girls to produce the transistor with uniform quality and characteristics.
This report covers the operation and mechanism concerning this machine in each stage of them and its own linear indexing mechanism.
