[0030] Example 1:
[0031] Such as figure 1 , figure 2 with image 3 As shown, the present invention discloses a near-field electrospinning effect on-line detection and regulation method based on machine vision. The needle tip voltage, wire traction speed, feed speed, etc. are all caused by the needle tip voltage, wire traction speed, and feed speed in the process of forming silk by printing. It is a one-way open-loop control. The silk diameter and the traction form of the silk are easily disturbed during the printing process, resulting in uneven silk diameter, silk bifurcation, and broken silk. However, it is sprayed in the traditional near-field electrospinning process. Detection and control mainly rely on manual observation cameras, so there are problems that the judgment is too subjective and the adjustment is difficult. Therefore, the present invention can provide a machine vision-based near-field electrospinning effect on-line detection and control method to solve the pro...
