Abstract

The invention relates to a cylindrical antenna spiral laser line device and a method thereof. The cylindrical antenna spiral laser line device comprises a raw material clamping and fixing jig and a laser bottom plate mechanism with a servo motor. The laser bottom plate mechanism with the servo motor is composed of a base, a large rotating shaft, a large bottom plate, a jig fixing base, a swing arm servo motor and a rotating servo motor. The raw material clamping and fixing jig is composed of a fixed raw material profiling jig block, a profiling jig block body and a profiling jig connecting and fixing block. By means of the design, integrated forming of the spiral antenna design is achieved, tedious steps of other design are omitted, waste caused in other design is saved, the overall time of the technological process is saved, stability of the whole process forming is greatly improved, and product efficiency and quality are greatly improved.

Description

[technical field] [0001] The invention relates to the technical field of cylindrical antenna spiral laser texture technology, in particular to a cylindrical antenna spiral laser texture device and a method thereof. [Background technique] [0002] In the production line production process, the general LDS (Laser-Direct-Structuring through laser direct structuring to achieve selective metallization on the molded carrier) process is limited to segmented on a plane or a similar plane. Various small areas of laser engraving, various straight line stripes, circular stripes, squares, parallelograms and other images can only form fixed graphic laser stripes on a certain plane or similar plane. It is very difficult for some products to form an overall perfect and uniform laser pattern on the cylindrical convex surface. [0003] First of all, the focal length and depth of laser are limited. In actual operation, only a small area of ​​the convex part of the cylindrical surface can be ...

Problems solved by technology

[0004] Secondly, under normal conditions, if we need to form spiral laser stripes, we must engrave the cylindrical spiral stripes in segments. After engraving the raised part into small segments, rotate the cylinder at a small angle, and then carve the small part, so as to gradually Complete the engraving of the entire spiral stripe. This method causes the spiral stripe to be spliced ​​with multiple small segments of laser stripes. The overall coherence is very low. Problems such as stitching misalignment

[0005] Finally, due to the inconsistency and inhomogeneity of the overall stripes and the inconsistency of the laser effect in the spliced ​​spiral laser stripes, the inhomogeneity and splicing dislocation of the overall plating surface will also appear after chemical plating, resulting in The spiral plating stripes do not meet the requirements of the actual antenna RF (radio frequency) test, and cannot really become the finished antenna we actually need

[0006] To sum up, the current laser engraving method basically cannot complete the realization of the spiral laser stripes of the cylindrical antenna. Even if it can be made, it does not meet the actual requirements of the product. The uneven stripes, spliced ​​and misplaced stripes, etc. do not conform to the appearance and actual function.
