Embodiment Construction

[0039] The specific implementation of the marking machine and its alignment method provided by the embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] The embodiment of the present invention provides a marking machine, such as figure 2 shown, including: carrier ( figure 2 not shown), a plurality of image acquirers C (such as CCD Camera, figure 2 represented by the projection of the image acquirer on the stage), the judgment module ( figure 2 not shown) and alarm module ( figure 2 not shown); where,

[0041] The stage is used to place the display substrate P to be marked;

[0042]Each image acquirer C is used to acquire images of the edges of the display substrate P and convert them into corresponding data information, and transmit the data information to the judgment module; wherein each image acquirer C is located directly above the stage, and The orthographic projection on the table is distri...

Abstract

The invention discloses a marking machine and an aligning method thereof. The marking machine comprises a carrying table, a plurality of image collectors, a judging module and an alarming module, wherein the periphery of a display substrate located on the carrying table correspond to the multiple image collectors used for collecting images; the numbers of the image collectors corresponding to the two opposite sides of the display substrate are equal, the image collectors corresponding to the two opposite sides of the display substrate correspond in a one-to-one mode, and thus a double-sided alignment system can be formed; image data collected by the image collectors on the two sides are measured together, the alignment values of the two sides are obtained correspondingly, and then whether alignment is abnormal or not is judged according to the fed back comparison of the double-sided alignment values and standard data. Compared with single-sided alignment judgment in the prior art, alignment abnormality can be judged more accurately through the double-sided alignment judgment, so that alignment alarms are controlled more effectively, and the equipment activation is improved; and the frequency of false alignment alarms caused by factors such as poor processes and deviated lenses of the image collectors can be greatly lowered, and the equipment activation is improved effectively.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a marking machine and an alignment method thereof. Background technique [0002] The marking machine is a kind of equipment used in the gluing photolithography process in the field of display panel manufacturing. Its main function is to complete the marking of the identification code ID of the glass substrate Glass and the identification code ID of the display substrate Panel. When the marking machine performs coding, it needs to align the substrate to ensure that there is no offset in the position of the substrate, so as to ensure that the position of the coding ID on the substrate meets the product design requirements. [0003] At present, the alignment principle of the existing marking machine is: figure 1 As shown, three image acquisition devices C (such as CCD Camera) corresponding to the edge of the substrate P take pictures of the two reference edges of the substrate and...
