Development of Shaking Table for Rapid Detection System of Microorganisms

Shaking table is an important component in rapid detection system of microorganisms. Based on the discussion regarding the advantage and shortage of the shaking table, this paper proposed a simple, reliable, and low-cost automatic shaking table. Three mechanisms were discussed with the achievement of reciprocating motion: slide-crank mechanism, follower-cam mechanism, and incomplete gear mechanism. The three mechanisms were compared in mechanical motion pair, motion form, component design, and manufacturing process. The slide-crank mechanism was finally determined. To overcome the strong oscillation of the liquid in the test tube along a single direction, this paper improved the slider-crank mechanism, and whose trajectory was modified into an irregular circle.
