Abstract

The invention relates to a printing machine and a scraper adjustment method, and belongs to the field of electronic manufacturing. The printing machine includes a base, a gantry, a scraper, a detection component, and a lifting component. The substrate to be printed of the stencil; the gantry is configured to drive the scraper to apply printing pressure to the printing mask; the detection component is configured to detect the height of the sealant printed at different positions on the substrate to be printed, and obtain the height of the sealant at different positions on the substrate to be printed The measured height of the dot-printed sealant; the lifting assembly is configured to adjust the distance between the different position points of the scraper and the abutment according to the measured height of the dot-printed sealant on the substrate to be printed, so as to adjust the height of the scraper The down pressure of different position points is adjusted. The invention shortens the adjustment time of the scraper and improves the adjustment efficiency. The invention is used for scraper adjustment.

Description

technical field [0001] The invention relates to the field of electronic manufacturing, in particular to a method for adjusting a printing machine and a scraper. Background technique [0002] In the manufacturing process of display screens such as organic light-emitting diode (Organic Light-Emitting Diode, OLED) display screens, glass substrates need to be packaged with glass glue. During packaging, a printing machine is usually used to print glass glue on the peripheral area of ​​the glass substrate through a screen printing process. [0003] A traditional printing machine usually includes: a gantry, a scraper and a base, the gantry is arranged above the base, and the scraper is arranged on the gantry and between the base and the gantry. When printing glass glue, the gantry drives the scraper to move linearly on the screen printing mask in a direction perpendicular to the length direction of the scraper, so that the glass glue on the screen printing mask passes through the ...
