Biological chip sample application device and usage thereof

Abstract

The invention discloses a biological chip sample application device comprising a linear guide rail composed of a longitudinally extending rail and a slide block clamped and sleeved on the rail; an electromagnet is installed on one end of the rail, and a slide block limiting component is arranged on the other end of the rail; and a magnetic suction piece is fixed on one end of the slide block, and a sample application needle assembly is fixed on the other end of the slide block. The sample application device provided by the invention has excellent beneficial effects of simple structure, stable performance, low cost, environmental protection, capability of guaranteeing fast and stable sample application speed on the condition of guaranteeing the sample application uniformity and low demand on a motor, so that the sample application device has very extensive application prospect.

Description

technical field [0001] The invention relates to a biochip spotting device and its application, belonging to the field of biotechnology. Background technique [0002] The drive of the biochip spotting device in the prior art generally adopts stepping motor or servo motor, and the stepping motor has the defects of poor driving ability, easy to lose steps (the machine is easy to be damaged), and slow speed, while the cost of the servo motor is high, Its specific structure and circuit structure are relatively complicated, and the control method requires high requirements, which is not conducive to the operation of non-professionals and the popularization of instruments. [0003] However, with the development of biochip technology, the demand for biochips has increased, and the requirements for biochip spotters have also been further improved, developing in the direction of higher precision, faster speed, higher efficiency, and wider applicability. Existing biochip spotters have...

Problems solved by technology

[0002] The biochip spotting device in the prior art is generally driven by a stepping motor or a servo motor. The stepping motor has the disadvantages of poor driving ability, easy loss of steps (the machine is easily damaged), and slow speed, while the cost of the servo motor is high. Its specific structure and circuit structure are relatively complicated, and the control method requires high requirements, which is not conducive to the operation of non-professionals and the popularization of instruments.

[0003] However, with the development of biochip technology, the demand for biochips has increased, and the requirements for biochip spotters have also been further improved, developing in the direction of higher precision, faster speed, higher efficiency, and wider applicability. Existing biochip spotters can no longer meet the needs of this rapid and large-scale production
