Key screen printing detection equipment

Abstract

The invention discloses key silk-screen detection equipment. The key silk-screen detection equipment comprises a conveying device, a detection device and a cleaning device, the conveying device comprises a driving element and a conveying part, the conveying part is connected with the driving element, and the driving element can drive the conveying part to move so as to drive the keys located on the conveying part. The detection device comprises a detection unit, and the detection unit is located above the conveying piece and used for detecting and positioning the key of the conveying piece. The cleaning device is located on the upstream of the detection device in the moving direction of the conveying piece and comprises a cleaning head, and the cleaning head is used for cleaning dust on the keys. According to the key silk-screen detection equipment, the dust on the silk-screen surface is removed by the head washing before key detection, so that the influence of the dust on the silk-screen detection is prevented, and the silk-screen detection precision is improved. Therefore, the yield is improved, and resource waste caused by false detection of excellent products can be avoided.

Description

technical field [0001] The invention relates to the technical field of screen printing detection, in particular to a key screen printing detection device Background technique [0002] In order to facilitate the use of the remote control, the buttons of the remote control are usually silk-screened with corresponding function characters on the front. However, due to the defects of characters in the process of silk screen printing, such as: lack of printing, reprinting, miscellaneous spots, and pinholes, etc., it needs to be recognized by instruments with visual inspection function. In the related art, since the keys may produce impurities and other ash adhered to the surface of the screen printing during the manufacturing process, resulting in false inspection, good products are classified as defective products, resulting in waste of resources, or defective products are classified as good products. products, resulting in a low yield rate. SUMMARY OF THE INVENTION [0003] ...

AI Technical Summary

Problems solved by technology

However, since the characters will have defects during the silk screen printing process, such as: lack of printing, reprinting, miscellaneous points, and pinholes, etc., it is necessary to use a visual inspection instrument to identify

In related technologies, during the manufacturing process of buttons, impurities such as dust may adhere to the surface of the silk screen, resulting in false inspections, so that good products are classified as defective products, resulting in waste of resources, or defective products are classified as good products. products, resulting in low yield
