Touch control writing brush head with conductive function and manufacture method thereof

Abstract

The invention discloses a touch control writing brush head with the conductive function and a manufacture method thereof. The method comprises the following steps: 1, conductive fiber bristles are obtained: after plastic raw materials are mixed into conductive carbon powder, the conductive fiber bristles are processed and obtained; 2, the conductive fiber bristle are integrated into a beam: the electro-conductive fiber bristles are integrated into the beam through mould rubber or a bundle of wires; 3, the finished product is obtained through assembly: one ends of the conductive fiber bristles integrated into the beam are fixed at one end of a metal sleeve pipe, and a bolt is fixed at the other end of the metal sleeve pipe, so that the writing brush head is obtained. According to the touch and control writing brush head with the conductive function provided by the invention, the conductive fiber bristle beam sleeved with the metal sleeve pipe is utilized to replace a human body finger and can perform touch and control operation to a capacitance touch screen, and the conductive fiber bristle beam has the soft texture, so that the smooth touch and control operation is realized and the screen cannot be scuffed, and the handwriting effect of a writing brush can be achieved during writing.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a touch brush tip with a conductive function and a manufacturing method thereof. Background technique [0002] With the gradual popularization of smart touch terminals, capacitive touch screens are also integrated into our lives. The capacitive touch screen is a four-layer composite glass screen. The inner surface and interlayer of the glass screen are coated with a layer of ITO (coated conductive glass), and the outermost layer is a thin layer of silica glass protective layer. The ITO coating is used as the working On the surface, four electrodes are drawn from the four corners, and the inner layer of ITO is a shielding layer to ensure a good working environment. When the finger touches the metal layer, due to the electric field of the human body, the user and the surface of the touch screen form a coupling capacitance, for high-frequency current, the capacitance is a direc...
