Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The method for alarming of ink-jet printing can be applied to the application environment shown in fig. 1, wherein the ink-jet control terminal 102 communicates with the ink-jet printing device 104 through a network, wherein the ink-jet control terminal 102 can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers and portable wearable devices, and the ink-jet printing device 104 is used for manufacturing O L ED devices.
For example, a Hole injection layer (Hole Inject L eye, HI L), a Hole transport layer (Hole transport L eye, HT L), a light Emitting layer (emissive Material L eye, EM L), etc. on the O L ED device, the functional Material ink can be injected into the Hole injection layer, the Hole transport layer and the pixel pits of the light Emitting layer by means of inkjet printing.
In order to facilitate understanding of the present application by those skilled in the art, the inkjet printing process of the embodiment of the present application will be described below with reference to fig. 2 and 3.
Fig. 2 is a schematic diagram of an inkjet printhead for making an O L ED device, from which an inkjet printhead 202 prints functional material ink 206 onto a glass substrate 204.
FIG. 3 is a schematic diagram of an inkjet printing scenario, in which a chamber 302 exists in an inkjet printing apparatus, before inkjet printing is performed, a glass substrate 304 is introduced into the chamber 302, so that an inkjet head of the inkjet printing apparatus ejects ink to pixel pits on the glass substrate 304. during a manufacturing process during O L ED, ink may be ejected using different functional material inks to form a multi-layer material film.
Therefore, the quality of the O L ED device is affected by the current manufacturing process of the O L ED device.
In one embodiment, as shown in fig. 4, an inkjet printing warning method is provided, which is described by taking the method as an example applied to the inkjet control terminal 102 in fig. 1, and includes the following steps:
step S402, acquiring a positioning mark of the ink-jet substrate.
The ink jet substrate may be a substrate of an O L ED device, and the ink jet substrate has a plurality of pixel pits, and the pixel pits can be sprayed with ink droplets.
The inkjet substrate may be provided with a positioning mark, and the positioning mark may be disposed at a specific position of the inkjet substrate, for example, pillars having a certain size are disposed at four diagonal positions of the inkjet substrate, respectively, and the group of pillars may constitute the positioning mark. Those skilled in the art can set the specific shape, material, and position of the positioning mark according to actual needs, which is not limited in this embodiment.
In a specific implementation, when the inkjet printing device 104 can detect that the inkjet substrate is transferred into the cavity of the inkjet printing device 104, the positioning identifier of the inkjet substrate in the cavity can be photographed to obtain an identifier image. The inkjet printing apparatus 104 transmits the identification image to the inkjet control terminal 102. The inkjet control terminal 102 may recognize the positioning mark according to the image feature of the mark image. Thereby, the inkjet control terminal 102 acquires the positioning mark of the inkjet substrate.
Step S404, acquiring the actual position corresponding to the positioning identifier.
The actual position may identify a current position for positioning. The coordinate plane can be set for the cavity of the ink-jet printing equipment, and each position in the cavity corresponds to one coordinate point. And the position of the positioning identifier in the cavity is determined, and the corresponding coordinate point is the position of the positioning identifier.
When the position of the inkjet substrate is shifted, the position of the positioning mark is shifted accordingly, so that the actual position of the positioning mark is different from the reference position. For example, the reference position of the positioning mark is (x)0，y0) After the ink-jet substrate is introduced into the cavity of the ink-jet printing equipment, the current actual position of the positioning mark is (x)1，y1)。(x0，y0) And (x)1，y1) With a certain distance between them.
In a specific implementation, the current position of the positioning identifier may be used as the actual position.
Step S406, generating alarm information according to the distance between the actual position and the set reference position; the alarm information is used for prompting that the position of the ink-jet substrate needs to be adjusted.
The reference position may be a position where the positioning mark is located after the inkjet substrate is corrected. In practice, the reference position can be identified by plane coordinates, for example, a reference position is (x, y).
In a specific implementation, the inkjet control terminal 102 may acquire the reference position by correcting the inkjet substrate. For example, an inkjet substrate is placed at a location within the cavity of the inkjet printing device 104, and accordingly, the location indicator of the inkjet substrate is also at a particular location. Then, an ink-jet printing task is executed, and when the ink drops ejected by the ink-jet head all fall into each pixel pit of the ink-jet substrate, the specific position where the positioning mark is currently located is used as a reference position. The inkjet control terminal 102 may store the reference position to recall the reference position for comparison when the actual position is acquired.
Of course, a person skilled in the art may obtain the reference position according to various ways, and the obtaining way of the reference position is not limited in the embodiment of the present invention.
The warning information may be used to prompt the user that the current placement position of the inkjet substrate deviates from the correct placement position, and if the inkjet substrate performs inkjet printing at the current placement position, ink of the inkjet head may fall outside the pixel pits, which affects the film thickness uniformity of the material film, so that the placement position of the inkjet substrate needs to be adjusted.
In a specific implementation, after the actual position of the positioning identifier is obtained, the inkjet control terminal 102 may compare the actual position with the reference position, and if the actual position is not consistent with the reference position, or if a difference between the actual position and the reference position is too large, may generate an alarm message to prompt a user to adjust the position of the inkjet substrate.
According to the warning method, the positioning mark of the ink-jet substrate is obtained through the ink-jet control terminal, and warning information for prompting the adjustment of the position of the ink-jet substrate is generated according to the distance between the actual position of the positioning mark and the reference position, so that the problems that the film thickness uniformity of a material film is influenced due to the position deviation of the ink-jet substrate are solved, and the quality of an O L ED device is improved.
In another embodiment, the step S406 includes:
calculating the distance between the reference position and the actual position to obtain the substrate offset; comparing the substrate offset with a preset offset threshold; and when the substrate offset is larger than the offset threshold, generating the alarm information.
In a specific implementation, the distance between the reference position and the actual position may be calculated, and the calculated distance may be used as the substrate offset. The substrate offset is compared to a preset offset threshold, and if the substrate offset is less than the offset threshold, an inkjet printing job can be executed. And if the substrate offset is greater than the offset threshold, generating alarm information.
In another embodiment, before the step S402, the method further includes:
receiving substrate incoming information of the ink-jet printing equipment; the substrate incoming information is generated when the inkjet substrate is detected to be incoming to the inkjet printing apparatus; displaying a position detection interface; the position detection interface is used for providing an instruction inlet; receiving a detection instruction submitted by a user through the instruction inlet; the detection instruction is used to trigger the execution of the step S402.
In a specific implementation, the inkjet printing apparatus 104 may be provided with a substrate sensing device, and the substrate sensing device may sense that the inkjet substrate is transmitted into the cavity of the inkjet printing apparatus 104, generate substrate transmission information accordingly, and transmit the substrate transmission information to the inkjet control terminal 102. After receiving the substrate incoming information, the inkjet control terminal 102 may display a position detection interface on the display screen, where the position detection interface may be provided with an instruction entry, and a user may submit a detection instruction through the instruction entry, so as to trigger the inkjet control terminal to execute processing for acquiring a positioning identifier of the inkjet substrate. For example, the position detection interface has a detection start button that the user can click to submit a detection command to the inkjet control terminal 102.
Fig. 5 is a schematic diagram of a position detection interface according to an embodiment of the invention. As can be seen, after receiving the substrate incoming message, the display screen of the inkjet control terminal may present a position detection interface 502. The position detection interface 502 has a detection start button 504, and when the user clicks the detection start button 504, the user can submit a detection instruction to trigger the inkjet control terminal to acquire the positioning identifier of the inkjet substrate.
In another embodiment, the step S402 includes:
sending a shooting instruction to the inkjet printing device; the ink-jet printing equipment is also used for shooting the positioning mark of the ink-jet substrate when receiving the shooting instruction, obtaining a mark image and feeding back the mark image; identifying the location marker in the marker image.
In particular implementations, the inkjet control terminal 102 may send a shooting instruction to the inkjet printing device 104. The cavity of the inkjet printing device 104 is internally provided with a camera device, the camera device can move to a certain camera shooting position, and in the camera shooting position, a certain area of the inkjet substrate is shot, and the area can contain a positioning mark of the inkjet substrate, and the area is shot, so that a mark image containing the positioning mark can be obtained. The inkjet printing apparatus 104 transmits the identification image to the inkjet control terminal 102 by its built-in transmission means. The inkjet control terminal 102 performs image recognition on the identification image, and identifies the positioning identification therein, so as to determine the current position of the positioning identification in the cavity as the actual position of the positioning identification.
In another embodiment, the location detection interface is further configured to display the warning information.
In a specific implementation, when the warning information is generated, the inkjet control terminal 102 may display the warning information on the position detection interface to prompt the user to adjust the placement position of the inkjet substrate.

Through the camera device of the ink-jet printing equipment, images can be collected aiming at a certain area of the ink-jet substrate so as to obtain an identification image containing the positioning identification.
To set the reference position, the inkjet substrate 601 may be placed at a position within the chamber of the inkjet printing apparatus and an inkjet printing job is performed. When the ink of the ink-jet head falls into the pixel pit 602, it indicates that the current position of the ink-jet substrate 601 in the cavity is accurate. The positions where the alignment marks 603a, 603b, and 603c of the inkjet substrate 601 are located are reference positions. The positioning markers 603a, 603b, and 603c are photographed by a camera, and a marker image is obtained. And the ink-jet control terminal determines the coordinate value of the current position of the positioning identifier according to the identifier image. For example, coordinate values (x) of the position 604a，ya) As a reference position of the positioning mark 603 a.

Before an inkjet printing task is executed, the inkjet substrate 601 is introduced into the cavity of the inkjet printing apparatus, and the position of the inkjet substrate 601 at this time is shifted, and the positioning marks 603a, 603b, and 603c are also shifted accordingly.
According to the embodiment of the present invention, the actual positions of the positioning marks 603a, 603b and 603c are obtained, and the coordinate values are used as the coordinate values of the current position of the positioning mark, so as to obtain the coordinate values (x ″) of the actual positionsa，y`a)、(x`b，y`b) And (x ″)c，y`c). Thereby, the actual positions of the three positioning marks are obtained.
Calculating the distance between the reference position and the actual position to obtain three basesPlate offset Da＝(xa-x`a，ya-y`a)，Db＝(xb-x`b，yb-y`b) And Dc＝(xc-x`c，yc-y`c). If the offset of any substrate is larger than the preset offset threshold D0It can be judged that the ink jet substrate is deviated and alarm information needs to be generated. For example, the distance between the actual position of the positioning mark 603a and the reference position 604 can be calculated, and when the distance is larger than the preset offset threshold D0And generating alarm information.
