Spraying surface defect detector

Abstract

The invention discloses a spraying surface defect detector. The spraying surface defect detector comprises a charging hole, a discharging hole, a feeding mechanism as well as a first CCD (charge coupled device) detecting module and a second CCD detecting module which are arranged between the charging hole and the discharging hole, wherein the first CCD detecting module is arranged close to the charging hole relative to the second CCD detecting module; the first CCD detecting module is used for carrying out CCD coarse detection on surface defects of products, and removing bad products which are detected to have predetermined larger surface defects; and the second CCD detecting module is used for carrying out CCD micro detection on surface defects of the products, and removing the bad products which are detected to have determined smaller surface defects. The spraying surface defect detector disclosed by the invention can be used for efficiently and precisely detecting spraying surface defects of the products.

Description

technical field [0001] The invention relates to a spraying surface defect detection machine. Background technique [0002] At present, most mobile phone cases in the mobile phone industry need to be sprayed on the surface to achieve the desired surface effect. However, there are many uncertain factors in the spraying process that will cause poor surface spraying effects. There is currently no very effective testing equipment for defective products. , are basically visually detected by the operator under the light and a magnifying glass. At the same time, the stability of manual detection is not high, and there are often missed detections, and some subtle spots are difficult to distinguish. If the detection time is long, it will easily lead to operator fatigue. Even cause adverse effects on the operator's vision. Contents of the invention [0003] The main purpose of the present invention is to provide an efficient, accurate and highly automated spraying surface defect det...
