Printing press and scraper adjustment method

Abstract

The invention relates to a printing press and a scraper adjustment method, and belongs to the field of electronic manufacturing. The printing press comprises an abutment, a gantry, a scraper, a detecting assembly and a lifting assembly, wherein the gantry is positioned above the abutment; the lifting assembly is arranged on the gantry; the scraper is arranged on the lifting assembly; the abutmentis configured to bear a to-be-printed substrate which is covered with a printing mask; the gantry is configured to drive the scraper to apply printing pressure to the printing mask; the detecting assembly is configured to detect the height of a sealant for printing at different position points of the to-be-printed substrate, so that the measured height of the sealant for printing at the differentposition points of the to-be-printed substrate can be acquired; and the lifting assembly is configured to adjust the distance between different position points of the scraper and the abutment according to the measured height of the sealant for printing at the different position points of the to-be-printed substrate, so that the press-down pressure on the different position points of the scraper can be adjusted. Through the scraper adjustment method provided by the invention, the scraper adjustment time can be shortened and the adjustment efficiency can be improved. The scraper adjustment method is applicable to 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 ...
