Abstract: Embodiments of the present disclosure provide a feeder system. The feeder system includes a rotary device configured to grip a container containing a material; and a controller electrically connected to the rotary device and configured to send a first rotation instruction to the rotary device so that the rotary device rotates the container. The rotary device is configured to rotate by a predetermined angle in response to the first rotation instruction sent by the controller, so that the material in the container is poured.

Abstract: The present disclosure discloses a screen printing system and a cleaning method thereof. The screen printing system has a scraper cleaning region and a working region, and the screen printing system includes a scraper and a scraper cleaning unit. The scraper operates within the working region, and the scraper cleaning unit is configured to clean the scraper. The scraper and the scraper cleaning unit are configured as follows: the scraper stays in the working region, and the scraper cleaning unit moves to a position where the scraper stays to clean the scraper; or the scraper cleaning unit is positioned in the scraper cleaning region, and the scraper moves to the scraper cleaning region, so that the scraper cleaning unit cleans the scraper.
