Abstract

The present disclosure relates to a marking method and device, and a repair system for a display panel in the field of display panel detection. The marking device includes: magnifying component and a marking component. The magnifying component is configured to magnify a target position point on a target object, and the marking component is configured to mark the target position point on the target object in accordance with the magnified target position point. The present disclosure may solve the problem that the operation process of marking the defective position point is complicated and simplify the operation process of marking the defective position point. The present disclosure may mark the defects of the display panel.

First claim

What is claimed is:

1. A marking device, comprising a magnifying component, a marking component, an adjusting component and an auxiliary adjusting component, wherein
the magnifying component is configured to magnify a target position point on a target object;
the marking component is configured to mark the target position point on the target object in accordance with the magnified target position point,
the adjusting component is connected to the marking component and configured to adjust a marking angle of the marking component to align the marking component with the target position point, and
the auxiliary adjusting component is disposed in the marking component and configured to assist the adjusting component in adjusting the marking angle of the marking component, wherein
the marking component comprises: an inkjet configured to jet ink to the target position point so as to mark the target position point,
the inkjet comprises an ink cartridge and a nozzle communicated with the ink cartridge, the auxiliary adjusting component comprises an infrared laser aligner, the infrared laser aligner is disposed in the nozzle and infrared rays emitted by the infrared laser aligner are collinear with an axis of the nozzle; and
the adjusting component is configured to adjust an ink jetting angle of the nozzle in accordance with the infrared rays emitted by the infrared laser aligner.

2. The device according to claim 1 , wherein the inkjet further comprises a recycling case communicated with the nozzle and configured to recycle residual ink in the nozzle.

3. The device according to claim 2 , wherein the adjusting component comprises an adjusting knob, an adjusting part and m adjusting gears meshed in sequence, and m is an integer greater than or equal to 1,
the adjusting knob is provided with a rotary gear, wherein the rotary gear is meshed with a first adjusting gear of the m adjusting gears, a shaft of a second adjusting gear of the m adjusting gears is fixedly connected to the adjusting part, the nozzle is fixedly disposed on the adjusting part, and the first adjusting gear and the second adjusting gear are adjusting gears disposed at both ends among the m adjusting gears meshed in sequence.

4. The device according to claim 3 , wherein the nozzle is a piezoelectric stack nozzle.

5. The device according to claim 4 , further comprising a power supply component connected to the piezoelectric stack nozzle and configured to supply power to the piezoelectric stack nozzle.

6. The device according to claim 5 , further comprising a control component electrically connected to the nozzle and the infrared laser aligner respectively and configured to control the infrared laser aligner to emit infrared rays and control the nozzle to jet ink.

7. The device according to claim 6 , wherein the control component comprises a nozzle switch electrically connected to the nozzle and an aligner switch electrically connected to the infrared laser aligner.

8. The device according to claim 7 , further comprising a jet head support of a hollow structure and provided with a knob opening and a nozzle opening, wherein the ink cartridge, the nozzle, the recycling case, the infrared laser aligner, the adjusting knob, the adjusting part, the m adjusting gears and the power supply component are all disposed in the jet head support, the adjusting knob partially extends out of the knob opening, and the ink jetted by the nozzle is enabled to be jetted out of the jet head support through the nozzle opening.

9. The device according to claim 8 , further comprising a magnifier body of a hollow structure and fixedly connected to the jet head support,
wherein the magnifying component comprises a magnifying lens disposed in the magnifier body.

10. The device according to claim 3 , wherein m is equal to 3.

11. The device according to claim 1 , wherein the nozzle is provided with a penetration hole, and the infrared laser aligner is enabled to pass the nozzle through the penetration hole.

12. The device according to claim 11 , wherein a value range of an aperture of the penetration hole is 20 micrometers to 30 micrometers.

13. A marking method of a marking device according to claim 1 , wherein the method comprises:
magnifying a target position point on a target object by the magnifying component; and
marking the target position point on the target object by the marking component in accordance with the magnified target position point.

14. The method according to claim 13 , before marking the target position point on the target object by the marking component in accordance with the magnified target position point, further comprising: adjusting a marking angle of the marking component by an adjusting component to align the marking component with the target position point.

15. The method according to claim 14 , wherein adjusting the marking angle of the marking component by an adjusting component comprises:
assisting the adjusting component in adjusting the marking angle of the marking component by an auxiliary adjusting component.

16. A repair system of a display panel, comprising a marking device according to claim 1 .
