Abstract

The present disclosure provides a printing system and a method for controlling a printing system. The printing system is used to print on a board, and includes at least one pair of adjustment assemblies. Each of the at least one pair of adjustment assemblies includes a carrying component, an alignment component and a drive component. The carrying component is configured to carry the board. The drive component is configured to be capable of driving the carrying component and the alignment component to move and is configured to adjust a distance between an upper surface of the carrying component and an upper surface of the alignment component to be equal to the thickness of the board. The structure of the printing system of the present disclosure enables a height difference between the upper surface of the alignment component and the upper surface of the carrying component to be adjusted according to the thickness of the board to be processed, such that the height difference between the upper surface of the alignment component and the upper surface of the carrying component is equal to the thickness of the board to be processed, so as to adapt to boards of different thicknesses to be processed.

Dependent claims

A printing system for printing a board, the printing system comprising:

at least one pair of adjustment assemblies, each of which comprises
a carrying component being configured to carry the board, and
an alignment component;
a drive component being configured to be capable of driving the carrying component and the alignment component to move and being configured to adjust a distance between an upper surface of the carrying component and an upper surface of the alignment component to be equal to the thickness of the board;
an actuation device coupled to the drive component, the actuation device being configured to move the drive component;
a control device coupled to the actuation device, the control device being configured to control an operation of the actuation device;
a first sensor coupled to the control device and configured to detect a height difference between the upper surface of the drive component and a lower surface of the carrying component;
and
a second sensor configured to detect whether an upper surface of the alignment component is attached to a lower surface of a wire screen,
wherein the control device further is configured to
obtain a thickness of a board, and
drive the carrying component and the alignment component from information received from the first sensor to adjust a height difference between an upper surface of the carrying component and an upper surface of the alignment component to be equal to the thickness of the board and making the upper surface of the carrying component to be lower than the upper surface of the alignment component.
