Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0033] Please refer to Figures 1-6 the figure, the handle conductive glue cutting method, the cutting method comprises the following steps:

[0034] Step S1: the handle and the conductive glue attached to the surface are wound in the cutting and winding equipment, and preliminary cutting is performed;

[0035] Step S2: an isolation film is attached to the handle and the conductive glue after cutting, for protecting the conductive glue attached to the handle;

[0036] Step S3: the avoidance film is cut and attached to the surface of the handle and the conductive glue with the isolation film attached;

When cutting the avoidance film, the avoidance film is an integral one, which facilitates the subsequent overall pulling of the waste. When pulling the waste, the isolation film can fix the position of the handle and the conductive glue main body without displacement and interference, thereby achieving precise control of waste removal.
