Embodiment Construction

[0022] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation, structure, features and effects of the present invention will be described in detail below in conjunction with the accompanying drawings and examples.

[0023] The marking equipment includes a controlled-movement marking component and a heating component. The marking component is coated with a phase-change material as a marker. After the phase-change material forms a wrong mark, the heating component heats the phase-change material into a gaseous state to remove all The above error flag.

[0024] Such as figure 1 and figure 2 As shown, in order to apply a mark to the object to be marked 500 , it is necessary to set up a working platform for placing the object to be marked 500 and applying a mark to the object to be marked 500 , that is, the marking table 100 . In this embodiment, the marking table 100 incl...

Abstract

The invention discloses marking equipment. The marking equipment comprises a marking assembly and a heating assembly which are controlled to move, wherein the marking assembly is coated with a phase-change material which is used as a marker; and after the phase-change material forms a wrong mark, the heating assembly is used for heating the phase-change material into a gaseous state, so that the wrong mark is removed. The marking equipment disclosed by the invention does not cause marker scrap; and moreover, the mark is easily removed, so that the marking equipment can mark again even the mark is wrong, and therefore, accuracy of the mark is improved, and the yield of the final product is increased.

Description

technical field [0001] The invention relates to a marking device and belongs to the technical field of display product peripheral devices. Background technique [0002] In the manufacturing process of display substrates, it is usually necessary to perform microscope (SEM, scanning electron microscope) measurement for defective analysis and pattern measurement. Due to the high magnification of the microscope, precise positioning is required for defective positions or measurement patterns, namely It involves the problem of target graphic positioning. [0003] At present, laser marking is mainly used for precise positioning of target graphics, that is, high-energy lasers are used to draw marks on products to be inspected (such as display substrates, etc.). The laser marking method to generate marks will cause irreversible damage to the product to be inspected (such as the film layer of the display substrate). Once the mark is wrong, the product needs to be scrapped. Therefore...
