An inkjet print head splicing correction system and correction method thereof

Abstract

The present application discloses an inkjet printhead splicing correction system and a correction method thereof, including a motion control device for controlling the inkjet printhead to be detected to drop ink droplets on a substrate; an observation device for acquiring an image of the ink droplets on the substrate ; a processor connected to the observation device and the motion control device; and an adjustment device connected to the motion control device and the inkjet print head; the processor receives the image acquired by the observation device and analyzes it image information, and transmit the analyzed image information to the motion control device, and the motion control device pushes the adjustment device to correct the splicing position of the inkjet print head. Solve the problem of inaccurate alignment of the nozzle device due to offset caused by the splicing of the inkjet print head due to processing or installation; at the same time, it avoids the movement error caused by the movement of the observation device and the problem of low correction accuracy caused by the lack of ink in some nozzle holes .

Description

technical field [0001] The present application relates to the technical field of printing, and in particular, to an inkjet print head splicing correction system and a correction method thereof. Background technique [0002] Inkjet printing has the advantages of simple and efficient processing and high material utilization, so it has been widely used in the manufacturing process of electronic devices. The way of head splicing into an array of inkjet print heads increases the printing width, thereby improving work efficiency. In order to achieve accurate printing of spliced ​​inkjet printing electronic devices, it is usually necessary to ensure that the angle formed by the dot matrix of ink droplets printed from the nozzle holes to the substrate is consistent. The beginning and end orifices of the ink print head should be at the same angle in the splicing direction with the end and the beginning end of the adjacent ink jet print head. [0003] However, due to processing erro...

Problems solved by technology

[0003] However, due to the processing errors, installation errors and size differences of the inkjet printheads in the parts, the misalignment of multiple inkjet printheads often occurs when splicing

In order to solve the above problems, the existing correction method is to record the position coordinates of each nozzle hole by moving the microscopic observation device, and then perform ink drop calibration; but the calibration data obtained in this way does not include the movement error of the display device, and also It does not take into account the situation that some nozzles do not eject ink, resulting in no improvement in the printing effect after correction; therefore, an inkjet printhead splicing correction method and a correction system are needed to correct the misaligned inkjet printhead module. To ensure the printing effect
