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
