Pseudo-coaxial visual laser repairing equipment

Abstract

The invention discloses pseudo-coaxial visual laser repairing equipment. The pseudo-coaxial visual laser repairing equipment comprises a jig moving platform and a laser visual part, wherein the jig moving platform is used for adjusting the position of a jig, and the laser visual part is used for capturing and repairing a product on the jig; the laser visual part comprises a laser head and a CCD camera, and a laser emitted by the laser head is reflected by a 45-degree reflector and then is coaxial with a visual light path of the CCD camera. The pseudo-coaxial visual laser repairing equipment is characterized in that the CCD camera is a color CCD camera, a lens of the CCD camera is a telecentric lens, and annular light sources are arranged on the upper side and the lower side of the 45-degree reflector correspondingly. When the product is repaired, the LAB color space of an image is analyzed in combination with independently researched and developed visual software, the background gray level of the product is automatically extracted, and the area, with the gray level higher than the background gray level, near split and the gray level increasing degree are recognized; then different laser powers are specifically adopted for fixed-point repair; the pseudo-coaxial visual laser repairing equipment has the advantages of high detection precision, high repair efficiency and good repair effect.

Description

technical field [0001] The invention relates to the technical field of laser processing equipment, in particular to a pseudo-coaxial vision laser repair equipment. Background technique [0002] Due to the many advantages of aluminum alloy materials such as high strength, light weight, strong texture, and low price, in 3C electronic products, more and more products will choose aluminum alloy materials as the frame and shell of the product. However, the use of aluminum alloy materials also has some disadvantages, especially in mobile phones, tablet computers and other products that have special requirements for signal reception, it is necessary to eliminate the electrostatic shielding generated by the entire metal frame. Here will involve an injection molding process - hot injection molding (Insertmolding). [0003] Thermal injection molding is a kind of insert molding, which is a molding method that inserts metal, plastic semi-finished products or other materials into a pre-...

AI Technical Summary

Problems solved by technology

Although this invention has the characteristics of high efficiency and no pollution to the environment; however, this invention only uses a camera to capture the white spots that appear on the surface of aluminum parts after oxidation, and then performs laser repair; and for the contact between injection molded parts and aluminum, The specifications of heterochromia are various and the degree of heterochromia is very complicated. It is difficult to achieve the purpose of repairing with the existing laser treatment method.
