Therefore, when the glass substrate is subjected to ink-jet printing, ink drops accurately drop in the pixel pits, and the uniformity of the film-forming thickness of the ink material on the glass substrate is improved.
In one embodiment, as shown in FIG. 3, a method for offset correction of a glass fixture is provided, which is illustrated by way of example in FIG. 1, and includes the steps of:
s310, detecting and acquiring a first position coordinate of a mark arranged on the glass clamp;
before this step, a two-dimensional or three-dimensional coordinate system of a glass jig moving space may be established, for example, as shown in fig. 4, in an inkjet printing apparatus, a three-dimensional coordinate system of three directions of X, Y, and Z may be established, in which a print head cage (inkrack) may carry a print head (Ink stick) to move in the X direction and the Z direction, and a glass substrate fixed on the glass jig may move in the Y direction.
The mark on the glass clamp can be one or more, if the mark is a plurality of marks, each mark is detected respectively, and the position coordinate of each mark is obtained.
For example, if the two ends of the glass clamp are respectively provided with the first identifier and the second identifier, the processor can control the first identifier to move to the position below the camera to obtain the coordinates of the first identifier as (X1, Y1), then control the glass clamp to move for a fixed distance (the distance between the first identifier and the second identifier is a fixed distance), and control the second identifier to move to the position below the camera to obtain the coordinate position of the second identifier (X2, Y2).

According to the technical scheme of the embodiment, the glass clamp is controlled to move back and forth along the moving path of the glass clamp during ink jet printing, so that the movement of the glass clamp during ink jet printing can be simulated to test the offset of the glass clamp, the testing accuracy is improved, the glass clamp is controlled to return to the initial position before the back and forth movement after the movement, and the offset of the position coordinates of the marks before and after the movement is conveniently compared.
And S330, acquiring the mark position offset before and after the glass clamp moves according to the set path according to the first position coordinate and the second position coordinate.
The identification position offset may be obtained by calculating a coordinate difference between the first position coordinate and the second position coordinate, where the coordinate difference may be a position coordinate difference obtained by subtracting the second position coordinate from the first position coordinate, or may be a position coordinate difference obtained by subtracting the first position coordinate from the second position coordinate.

The shift of the mark position of the glass holder before and after the movement can be seen with reference to fig. 5, and the glass holder may shift from the mark position 510a to the mark position 510b and the mark position 520a to the mark position 520b after moving along the set path (the dotted line position shown in fig. 5) to the mark position before the movement (the solid line position shown in fig. 5).
In this step, the processor may obtain an amount of displacement of the mark position before and after the movement of the glass jig according to the set path by comparing a difference between the first position coordinate before the movement of the mark on the glass jig and the second position coordinate after the movement.

s660, if the judged position offset of the first mark or the judged position offset of the second mark exceeds a set offset threshold, resetting the origin of the glass clamp so as to correct the offset of the position of the glass clamp;
and S670, if the judged position offset amount of the first mark and the judged position offset amount of the second mark do not exceed the set offset threshold value, judging that the ink-jet printing can be carried out on the glass substrate.
The offset correction method of the glass clamp avoids the problem that the offset of the movement of the glass clamp cannot be detected in the long-term accumulation process in the ink-jet printing process, so that the equipment is abnormally stopped or ink drops deviate out of the pixel pits in the ink-jet printing process, ensures that the ink material accurately drops in the pixel pits in the ink-jet printing process in the manufacturing of an O L ED device, and improves the film thickness uniformity of the ink material on the whole surface of the glass substrate.
