Abstract
The present invention relates to a kind of measurement welder for OLED mask plate, including the pattern measuring object under test measuring unit, fixing object will be needed to be fixed to fixed cell on other object；Measuring unit includes metal mask plate surface shape measurement subelement and metal mask plate measure of precision subelement；Metal mask plate surface shape measurement subelement is height sensor, amesdial or three-coordinate measuring probe, and metal mask plate measure of precision subelement includes CCD camera and optical lens；Fixed cell is laser-welding machine；Measuring unit controls with the most controlled system of described fixed cell；Measuring welder to be fixed on described motion, described motion makes described measurement welder the mask plate of the most measured welding to move on six dimensional orientations.Template quality detection and the template in OLED mask plate making later stage are fixed and are incorporated into integral mechanism by the present invention, have saved the occupy-place of board space, and have decreased the triviality of operation, artificial cost and the production cycle of OLED mask plate.
Description
Technical field
The present invention relates to a kind of machinery, be specifically related to a kind of measurement welder for OLED mask plate.
Background technology
The characteristics such as the self-luminous of OLED, ultra-thin, fast response time, wide viewing angle, low-power consumption make the mobile phone of lift-launch OLED screen make us pursuing.At present, OLED the most tentatively establishes the status as third generation display leading nucleus, and along with maturation and the breakthrough of large scale batch production technique of technology, OLED product will extend to more large scale.
Vacuum mask evaporation is the main method preparing OLED luminescent layer, and the material used by OLED mask plate is invar (Invar) alloy that thermal coefficient of expansion is extremely low, and the thickness of usual mask plate only has 40 μm, with millions of small rectangular pixels.Use several mask plates owing to using the color OLED of three-color light-emitting material to need in the fabrication process successively, thus the required precision to mask plate is the highest.Therefore, each link in the making of OLED mask plate is the most crucial, wherein the mask plate made is carried out positional precision, the detection of openings of sizes and mask plate is fixed on screen frame as OLED mask plate make later stage work, its be final OLED mask plate quality quality decisive link.
Because the development of OLED industry remained unchanged in the elementary step, various place that need to improve is there is in it produces each link of chain, traditional measuring method is to use three-dimensional measuring instrument to measure, and OLED mask plate is fixed on screen frame by mode or the mode of directly clamping that then employing glue is bonding.Quality Detection and the fixing operating procedure of OLED mask plate are numerous and diverse, have a strong impact on production efficiency.
Summary of the invention
It is an object of the invention to provide a kind of measurement welder, Quality Detection and the fixing operating procedure that can solve OLED mask plate in prior art are numerous and diverse, the problem having a strong impact on production efficiency, the present invention mainly realizes Unification of diverse by fixing to Quality Detection and mask plate.
For problem above, the present invention proposes below scheme:
A kind of measurement welder, it is characterised in that including: measuring unit, described measuring unit is for measuring the pattern of object under test；Fixed cell, described fixed cell is for needing fixing object to be fixed to other object.
Further, described measuring unit includes metal mask plate surface shape measurement subelement and metal mask plate measure of precision subelement.
Further, described metal mask plate surface shape measurement subelement is survey tool；Described metal mask plate measure of precision subelement includes CCD camera and optical lens.
Further, described metal mask plate surface shape measurement subelement is height sensor, amesdial or three-coordinate measuring probe.
Further, described fixed cell is laser-welding machine.
Further, welder also includes control system, and described control system connects described measuring unit and described fixed cell by holding wire, and described measuring unit controls with the most controlled system of described fixed cell.
Further, welder also includes that motion, described measurement welder are fixed on described motion, and described motion makes described measurement welder the mask plate of the most measured welding to move on six dimensional orientations.
Further, described motion is under control of the control system.
Template quality detection and the template in OLED mask plate making later stage are fixed and are incorporated into integral mechanism by the present invention, have saved the occupy-place of board space, and have decreased the triviality of operation, artificial cost and the production cycle of OLED mask plate.

Comparison Fig. 2 is explained as follows further, and described measuring unit includes: metal mask plate surface shape measurement subelement 21, and described metal mask plate surface shape measurement subelement 21 is contactless height sensor, it is also possible to be the survey tool such as amesdial of contact；Metal mask plate measure of precision subelement, described metal mask plate measure of precision subelement 22 includes CCD camera 221 and optical lens 222.Described fixed cell 23 is laser-welding machine, and metal mold mask plate can be welded on screen frame be fixed by it.Described measurement welder is integrally attached on motion 24, as in figure 2 it is shown, described welding measurement apparatus can be moved with in the vertical direction guide rail along motion 24, motion 24 can slide on crossbeam I,
As it is shown in figure 1, described crossbeam I can move along shown moving direction on bracing frame II.The above measuring unit 21,22, fixed cell 23 and motion 24 are by control system control, under control of the control system, described measurement welder can the mask plate of the most measured welding move on six dimensional orientations, control system not shown in the present embodiment.
Above example is intended to indicate that the present invention, rather than limits the scope of the invention, other cellular construction of equivalent action can replace relating to cellular construction in embodiment and be within the scope of the present invention.
