Embodiment Construction

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the understanding of the present disclosure will be better and more comprehensive.

[0026] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. ...

Abstract

The invention relates to a laser carving method. The method comprises the following steps that S100, base materials are provided and machined to form an intermediate product; S200, a laser carving face and a machining face are determined, the machining face is opposite to the laser carving face, a laser carving area located on the laser carving face is determined, a machining area located on the machining face is determined, and the machining area corresponds to the laser carving area; S300, machining is carried out on the machining face so that the machining area can be concaved to a certaindepth; and S400, laser carving is carried out on the laser carving area on the laser carving face. After a middle frame is subjected to laser carving, the follow-up working procedure of assembling a display screen is not affected; when laser carving is carried out on the middle frame with a plastic injection molding function, the problem that the waterproof performance of the middle frame is lowered since the aluminum-plastic joint is cracked during planar shaping is avoided, the yield is improved, the production cost is greatly reduced, and an obvious significance is achieved in practical production. In addition, the shaping working procedure is not needed, and the time cost and the machining cost are saved.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to a laser engraving method. Background technique [0002] With the trend of ultra-thin and large-screen smart phones, in order to strengthen the overall strength of the mobile phone and improve the user's tactile experience, smart phones have adopted a large-scale metal middle frame as the body. [0003] At present, the metal middle frame generally includes the following processing steps. The blank is processed by a CNC machining milling machine, the CNC processed parts are put into a plastic mold for plastic injection molding, and then the conductive position of the inner cavity of the middle frame of the mobile phone is laser engraved. After laser engraving, the middle frame of the mobile phone will be arched and deformed to the other side of the radium engraved surface. When the arched deformation reaches a certain level, it will affect the subsequent process of assembl...
