Abstract
The invention relates to a measuring and welding device of an OLED (Organic Light Emitting Diode) mask plate, comprising a measuring unit used for measuring the shape and appearance of an object to be measured, and a fixing unit used for fixing an object to be fixed on other objects, wherein the measuring unit comprises a metal mask plate surface shape measuring subunit and a metal mask plate precision measuring subunit; the metal mask plate surface shape measuring subunit is a height sensor, a dial indicator or a three-coordinate measuring head; the metal mask plate precision measuring subunit comprises a CCD (Charge Coupled Device) camera and an optical lens; the fixing unit is a laser welder; the measuring unit and the fixing unit are both controlled by a control system; and the measuring and welding device is fixed on a movement mechanism which is capable of making the measuring and welding device move in six dimensional orientations relative to the measured and welded mask plate. According to the measuring and welding device, mask plate quality detection at the later period of OLED mask plate production and mask plate fixation are integrated into a whole mechanism, machine station space occupation is reduced, operating complexity is lowered, labor cost is saved, and the production period of OLED mask plates is shortened.
Description
Technical field
The present invention relates to a kind of mechanical device, be specifically related to a kind of measurement welder for the OLED mask plate.
Background technology
Characteristics such as self-luminous, the ultralight of OLED is thin, response speed is fast, wide visual angle, low-power consumption make the mobile phone that carries the OLED screen make us pursuing.At present, OLED has tentatively established the status as third generation display leading nucleus, and along with the maturation of technology and the breakthrough of large scale batch production technique, the OLED product will be to more large scale extension.
The vacuum mask evaporation is the main method of preparation OLED luminescent layer, and the used material of OLED mask is the extremely low invar of thermal coefficient of expansion (Invar) alloy, and the thickness of mask has only 40 μ m usually, has millions of small rectangular pixels.Because it is use the color OLED of three-color light-emitting material in manufacture process, to need successively to use several masks, thereby very high to the required precision of mask.Therefore, each link in the making of OLED mask plate is very crucial, wherein the mask plate of making is carried out the detection of positional precision, openings of sizes and mask plate is fixed on the later stage work of making as the OLED mask plate on the screen frame, it is the decisive link of the quality quality of final OLED mask plate.
Because of the development of OLED industry still in the elementary step, in each link of its production chain, there is the improved place of various urgent need, traditional measuring method is to adopt three-dimensional measuring instrument to measure, and adopts the mode of the bonding mode of glue or directly clamping that the OLED mask plate is fixed on the screen frame then.The Quality Detection of OLED mask plate and fixing operation step are numerous and diverse, have a strong impact on production efficiency.
Summary of the invention
The purpose of this invention is to provide a kind of measurement welder, Quality Detection and the fixing operation step that can solve OLED mask plate in the prior art are numerous and diverse, have a strong impact on the problem of production efficiency, the present invention mainly is with Quality Detection and the polynary integration of the fixing realization of mask plate.
At above problem, the present invention proposes following scheme:
A kind of measurement welder is characterized in that, comprising: measuring unit, and described measuring unit is used for measuring the pattern of object under test; Fixed cell, the object that described fixed cell is used for will needing to fix is fixed to other object.
Further, described measuring unit comprises metal mask plate surface shape measurement subelement and metal mask plate precision measure subelement.
Further, described metal mask plate surface shape measurement subelement is survey tool; Described metal mask plate precision measure subelement comprises CCD camera and optical lens.
Further, described metal mask plate surface shape measurement subelement is height sensor, amesdial or three-dimensional coordinates measurement head.
Further, described fixed cell is laser-welding machine.
Further, welder also comprises control system, and described control system connects described measuring unit and described fixed cell by holding wire, all controlled system control of described measuring unit and described fixed cell.
Further, welder also comprises motion, and described measurement welder is fixed on the described motion, and described motion can move described measurement welder relative to the mask plate of measured welding at six dimensional orientations.
Further, described motion is under the control of control system.
The template quality that the present invention makes the later stage with the OLED mask plate detects and template fixedly is incorporated into integral mechanism, saved the occupy-place of board space, and has reduced the loaded down with trivial details property of operating, artificial cost and the production cycle of OLED mask plate.
