Example Embodiment

[0034] Example 1: Preparation of flat metal antenna made of copper

Example Embodiment

[0035] The material of the plastic shell is PC. A copper planar antenna pattern with a thickness of 30 μm is prepared on the plastic shell. The implementation plan is as follows:

[0036] S1. Put the shell to be processed into the jig, and put the jig into the forming cylinder. Adjust the laser power output of the fiber laser to 10W, set the scanning path of the laser on the computer, and output the laser to the surface of the shell through the laser coaxial powder feeding nozzle through the optical path system. The laser engraving and removing the thickness of the plastic shell 30μm plastic to form the antenna pattern;

[0037] S2. The three-dimensional CAD model of the antenna is sliced ​​and separated, converted into two-dimensional plane data, and the data is transmitted to the laser beam displacement control system to generate the scanning trajectory of the laser beam;

[0038] S3. Adjust the output power of the fiber laser to 40W, and pass argon protection into the forming c...

Example Embodiment

[0039] Embodiment 2: Preparation of a three-dimensional metal antenna made of silver

[0040] The material of the plastic shell is PC / ABS. A three-dimensional antenna pattern made of silver is prepared on two mutually perpendicular surfaces of the plastic shell, and the thickness of the antenna on the two surfaces is 24 μm. The implementation plan is as follows:

[0041] S1. Put the shell to be processed into a jig that can rotate 90o, and put the jig into a forming cylinder. Adjust the laser power output of the fiber laser to 10W, set the scanning path of the laser on the computer, and output the laser to the shell surface through the optical path system through the coaxial nozzle. First, laser engrave and remove the plastic shell. The thickness is 24μm. The plastic that forms part of the antenna pattern; then rotate the jig 90o, and use laser laser engraving to remove the plastic with a thickness of 24μm on the other surface to form the pattern of the remaining part of the ante...

Abstract

The invention discloses a method for forming an antenna or a circuit on a plastic cement casing. The method comprises the following steps that in a material accumulation step, the scanning is carried out on the plastic cement casing according to preset patterns in a mode that laser at the first power and metal powder are axially output in a coupled way, the laser is emitted while the coaxial powder conveying is carried out, the coaxially conveyed metal powder is melted by the laser, in addition, the melted metal powder is solidified and deposited on the plastic cement casing, and after the accumulation layer by layer, the antenna or the circuit with the patterns is formed. The method has the advantages that the complicated three-dimensional antenna and circuit structures can be simply, conveniently and fast manufactured on a plastic casing.

Description

technical field [0001] The invention relates to the manufacture of antennas for electronic products, in particular to a method for forming antennas or circuits on plastic casings. Background technique [0002] As smartphones become thinner and lighter, traditional mobile phone antenna manufacturing methods have been difficult to meet the design requirements of compact, three-dimensional curved antennas and other antennas. For example, two-color injection molding, this technology needs to manufacture the injection mold of the antenna, the modification process of the mold is complex and costly, and it is difficult to manufacture a complex three-dimensional antenna structure. In this context, some new mobile phone antenna manufacturing technologies have emerged, such as LDS technology and printed antennas. Among them, LDS technology has been widely concerned because of its many advantages. One of the advantages of LDS technology is to use laser to directly engrave the pattern...
