Abstract

The invention provides a laser following type position detection system, which comprises a following actuating device, a laser distance measuring sensor, a grating ruler and a grating reading head, and is characterized in that the grating ruler and the following actuating device are arranged in parallel; the laser distance measuring sensor and the grating reading head are arranged on the following actuating device and perform linear reciprocating motion through actuating of the following actuating device; the laser distance measuring sensor and the grating reading head are installed at the same position of the following actuating device, and the laser distance measuring sensor and the grating reading head are oppositely arranged. The grating reading head faces the grating ruler, and the linear displacement of the laser distance measuring sensor is obtained through the grating ruler and the grating reading head. The invention further provides a laser following type position detection method. According to the laser following type position detection system and method provided by the invention, following type detection can be carried out, the structure is simple, the cost is low, the detection precision is high, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of biological cell processing, in particular to a laser following position detection system and method. Background technique [0002] At present, when processing biological cells, cell separation technology is involved, and a separation cup is often required. The biological cell fluid is subjected to gradient separation through the high-speed rotation of the separation cup, thereby separating different types of cells. The separation cup can achieve a good cell separation effect, but it is necessary to use a sensor to measure the volume of the cell fluid in the separation cup, so as to judge whether the cell separation system performs corresponding actions, such as refilling the separation cup with cell fluid; excluding all cells Liquid; start centrifugation and other actions. [0003] In the prior art, measuring the volume of cell fluid in the separation cup by sensors is usually solved in the following way...
