Abstract:
1. A device for biochip hybridization or washing, comprising: a) a carousel; b) a translational movement controller comprising a base, a sliding rail on the base, a slide block on the sliding rail, a translational movement motor, and a driving assembly that couples the motor to the slide block; and c) a revolving movement controller comprising a base, a revolving movement motor, an eccentric block coupled to the revolving movement motor, a pendulum shaft comprising an upper shaft and a lower shaft connected to each other via a bearing, a rotary disk fixed on the upper shaft and a plurality of springs that connect the rotary disk to the base and pulls the rotary disk from rotating, and a photoelectric sensor, wherein the lower shaft is connected to the eccentric block and the upper shaft is connected to the carousel, wherein the revolving movement controller is placed on the slide block of the translational movement controller, and wherein the photoelectric sensor senses the stop of the revolving movement controller and triggers the start of the translational movement controller, thereby brings the carousel to a horizontal position.
