Abstract:

In order to improve the effect of robot in the process of garment customization, unstable adsorption of the robot end-effector during grabbing and transferring fabric was worked on. The key factors of electrostatic plate design, the shape arrangement and structure parameters of the electrode plate were analyzed and optimized. The model of knitted weft knitted fabric was constructed, the four electrode distribution forms were simulated and compared, and the most suitable shape arrangement for garment fabric of the electrode plate: the comb electrode was obtained. The shape arrangement and structural parameters of the electrode plate were then optimized with the objective of maximizing the adsorption capacity per unit area. The simulation results show that the electrode with comb-shaped arrangement and optimized structure parameters can grab garment fabrics well, meeting the requirements for automatic garment production.

Key words: electrostatic adsorption, fabric grasping, electrode optimization, fabric modeling, electrostatic force, intellectualizationof grarment processing
