Example Embodiment

[0039] Example 1

[0040] This embodiment is a process for preparing the shell of a basic outsourcing earphone used in audiovisual equipment. The shell is as figure 2 Shown.

[0041] In this embodiment, a carbon fiber cloth woven with carbon fiber filaments with a diameter of 6.9 μm is selected. First, the carbon fiber cloth is immersed in a modified thermoplastic epoxy resin, and the thickness after the immersion is completed is about 0.65 mm. Then it is coated with PC customized special film, the thickness of the upper and lower layers is about 0.045mm respectively. The above-mentioned impregnation and coating process can use the existing mature process.

[0042] The customized carbon fiber sheet obtained above is formed in the mold:

[0043] ① Preheat the mold for 3 minutes, and then put the processed customized carbon fiber sheet above the lower mold.

[0044] ②Heat the upper and lower molds so that the upper and lower molds reach about 160 degrees Celsius. At the same time, infr...

Example Embodiment

[0048] Example 2

[0049] This embodiment is the manufacturing process of the shell of the earphone with antenna, and the shell part is as Figure 4 Shown.

[0050] In this embodiment, a carbon fiber cloth woven with carbon fiber filaments with a diameter of 7.2 μm is selected, and the carbon fiber cloth is first impregnated in PC resin, and the thickness after the impregnation is completed is about 0.75 mm. Then cover the PMMA customized special film, the thickness of the upper and lower layers is about 0.050mm respectively. The above-mentioned impregnation and coating process can use the existing mature process.

Abstract

The invention discloses a carbon fibre material thermoplastic processing forming process for a head-mounted audio-visual and communication equipment shell. The carbon fibre material thermoplastic processing forming process adopts mould pressing forming and comprises the following steps: (1) preheating a mould, and then placing a customized carbon fibre plate on a lower mould; (2) heating the lowermould and an upper mould, and simultaneously, heating by using an infrared device; (3) pressing the upper mould and the lower mould, and keeping temperature and keeping pressure; and (4) cooling, demoulding, and then gluing, wherein the customized carbon fibre plate is obtained by weaving carbon fibre cloth first by carbon fibre filaments, dipping the carbon fibre cloth in thermo-reversible resin, and coating the upper layer and the lower layer of the outer surface of the carbon fibre cloth with customized special films, wherein the customized special films are resin films. According to the carbon fibre material thermoplastic processing forming process for the head-mounted audio-visual and communication equipment shell, a high-gloss shell is directly formed by using a sheet carbon fibre material in the mode of selecting a resin material and laminating the films by using specific resin films after the carbon fibre cloth is dipped and matching specific process conditions; and the shellis not required to the polished and ground completely after being formed, has a mirror surface effect naturally, and has uniform thickness and extremely good visual sense.

Description

technical field [0001] The invention relates to the field of communication and audio-visual equipment, in particular to a new material production process for head-mounted equipment. Background technique [0002] For head-mounted communication and audio-visual equipment, due to the special needs of wearing on the head, its weight, comfort and appearance are all factors that need to be considered in the selection of materials and processes. [0003] The existing mature technology for forming shells is to use plastic injection molding, but the weight of plastic shells is still relatively large, which will bring a heavy burden during long-term use, and at the same time limit the increase in the functionality of the earphones and limit the possibility of expanding use scenarios sex. In addition, surface treatment such as spraying is required in the later stage of processing, which will cause serious environmental pollution. [0004] Therefore, generally speaking, the existing p...
