A substrate support platform for curved surface printing

Abstract

The invention discloses a substrate supporting platform for curved surface printing, which includes a linear guide rail installed on a substrate, and four sliding seats are sequentially installed on the linear guide rail from left to right; the second and third sliding seats are movably connected by a locking assembly Base plate; the first and second sliding seats and the third and fourth sliding seats are respectively connected by cylinders; the first sliding seat is equipped with a left rotation module, the second sliding seat is equipped with a left support wheel group, and the third sliding seat is equipped with a right support wheel A right rotation module is installed on the group and the fourth sliding seat, and the right rotation shaft is connected with the rotation driving mechanism. The substrate is actively rotated, which can accurately determine the starting position, end position and pick-and-place position of the substrate rotation, which is convenient for multiple printings and ensures high precision; the feeding is convenient and accurate, and the substrate can automatically fall off from the fixture , easy to pick and place; can adapt to the processing of various specifications of substrates.

Description

technical field [0001] The invention relates to a curved screen printing device. Background technique [0002] Curved surface printing refers to the printing of substrates with curved surfaces. In the existing curved surface printing equipment, the substrate is fixed by the movable clamp, so that the substrate moves passively with the movement of the scraper, so as to ensure that the printing speed of the scraper is synchronized with the rotation of the substrate, and the graphics on the screen will be accurate during the printing process. transferred to the substrate surface. [0003] However, in the existing equipment, the substrate is passively rotated, so that the position of the substrate needs to be adjusted each time during multiple printings, which reduces the printing efficiency; the supporting platform of the existing substrate can only be used for a specific size of the substrate , the scope of application is small; it is inconvenient to take and place the exist...
