In view of the fact that the current research on chip stripping is mostly focused on the structural design,arrangement of needle and stripping process parameters,while the influence of needle cover and the process parameters associated with needle cover in the process of chip stripping is ignored,a blue tape fixed area adjustable needle cover device was designed,the fixed area of blue tape was adjusted through the structural transformation of the internal gas path of the needle cover.Then orthogonal experimental method was used to analyze the influence of the fixed area of the blue tape and the vacuum adsorption at the bottom of the blue tape on the chip stripping.It is concluded that the influence of the fixed area of the blue tape on the chip peeling is ten times that of the vacuum adsorption at the bottom of the blue tape.The necessity of designing the device is verified.Then the feasibility of the adjustable blue tape fixed area needle cover device is analyzed and verified by using the fluid module in ANSYS software.
