Description

Technical Field

[0001] The utility model relates to the technical field of cover plate production, in particular to a detection structure capable of predicting light leakage from a pinhole in an ink zone. Background Art

[0002] The cover plate needs screen printing ink during the production process. The screen printing sequence of traditional screen printing ink for cover plates is: cleaning before screen printing - screen printing SY1 (surface drying) - screen printing reverse cover (curing) - screen printing logo / printing oil (surface drying) - screen printing cover (full line curing), etc. In the process of screen printing ink, it is easy to have many small round holes like pinholes around the ink area of ​​the product, and many tiny holes in the non-printing area (pinholes are the "honeycomb eyes" of the ink). Once the above "sand eyes" appear, it is difficult to remedy. The only way is to remove the ink from the product, polish it, re-repair it, and then screen print the ink.

[0003] In the prior art, the main factors affecting the occurrence of "sand holes" in the screen during the screen printing of cover ink are the aging and attenuation of the exposure lamp energy. Insufficient exposure affects the curing of the photosensitive paste, which is washed away during development and causes sand holes. In the screen printing process, one of the steps is the surface drying / curing process of the ink. The energy of the exposure lamp + curing time is required to thermally cure and stabilize the ink state. When sand holes are found during the production process, the energy of the exposure machine needs to be tested manually in a timely manner. Manual testing of the energy of the exposure machine is troublesome and cannot be performed in real time to find problems in a timely manner. Utility Model Content
