Oscillating movement control device and control method

Abstract

The invention discloses an oscillating movement control device for an automatic blood culture instrument. The oscillating movement control device comprises a base, a fixed rack, motors and swing frames, wherein the motors are arranged on the base; the fixed rack is fixedly arranged on the base; the swing frames are hinged with the fixed rack. By adopting the oscillating movement control device, the motors are fixedly connected with speed reducers through screws; the speed reducers are connected with the swing frames through first connecting rods; a plurality of detection holes are distributed on the swing frames; a corresponding detection device is fixedly arranged on the back side of each detection hole, so that the quantity of the swing racks can be increased according to the required quantity of the detection holes, and the quantity of the motors also can be increased according to the limitation of motor load. Similar combinations of a plurality of groups of motors, a plurality of groups of speed reducers, plurality of groups of swing frames and the like are arranged inside the overall oscillating movement control device, so as to form a reciprocating oscillating movement control process. The oscillating movement control device and control method thereof disclosed by the invention are convenient to expand, the oscillating movement control device is simple in structure, and the detection time of the automatic blood culture instrument can be shortened.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a swing motion control device for an automatic blood culture instrument and a control method thereof. Background technique [0002] At present, automatic blood culture instruments have gradually replaced manual culture. Automatic blood culture is divided into two parts: constant temperature incubation and detection. The realization of the functions of these two parts is inseparable from motion control. [0003] An existing motion control method applied to a blood culture instrument is rotary, such as the Chinese invention patent with the publication number CN103045471A, the rotary motion control device for a full-automatic blood bacteria culture instrument includes a turntable, a stepping motor, Signal control processing unit, positioning block, initial position sensor, the turntable is distributed with multiple specimen positions for placing blood culture bottles, the po...
