Abstract
The invention discloses a method for detecting the perforation precision of a steel mesh, and the method specifically comprises the steps: enabling the Gerber data of a corresponding substrate to be imported into a steel mesh management system, wherein the steel mesh management system draws forms template information at the same scale as a real substrate according to the Gerber data; placing the steel mesh on a steel mesh placing platform, and enabling the steel mesh management system to drive a servo motor driver in a mechanical motion module through a motion control card when a high-definition industrial camera carries out the photographing; enabling the servo motor driver to drive the high-definition industrial camera on a sliding rail to obtain the image information of different positions of the substrate; S4, enabling the steel mesh management system to extract the perforation and shape information of the steel mesh from the image information, and detecting whether the perforation and shape accord with the standard or not. The method can detect the perforation size and shape of the steel mesh more precisely, and greatly improves the printing quality of solder paste.
Description
Technical field
The invention belongs to SMT industry printing technologies, more particularly to a kind of detection method of steel mesh perforate accuracy.
Background technology
Surface mounting technology SMT mainly includes：Paste solder printing, accurate paster, reflow soldering.Wherein solder(ing) paste printing quality
Maximum is affected on the quality of SMT products, statistics shows, due to caused by solder(ing) paste printing quality when current SMT is most of bad
, and steel mesh is essential in typography, its quality directly affects the quality of printing work, the thickness of steel mesh and perforate
Size determines the number to be printed of soldering paste, and tin cream amount can excessively cause bridging, and tin cream amount crosses that I haven't seen you for ages and produce that tin cream is not enough or rosin joint.Steel
Whether the hole shape and perforated wall of net are smooth also to affect quality of mold release.
The content of the invention
In view of the foregoing defects the prior art has, this application provides a kind of detection method of steel mesh perforate accuracy,
Solve the problems, such as the steel mesh perforate accuracy in typography in SMT industries.
