Technical field
The present invention relates to the devices and methods therefor of a kind of Ultra-Violet Laser, relate in particular to a kind of devices and methods therefor that is used for touch-screen and the inner mark of panel computer glass at the transparent material inner marker.
Background technology
Because the variation that handset touch panel and panel computer industry are processed mode, urgent need will etch location mark mark in clear glass inside, this location mark is as the fiducial mark of follow-up glass tempering, ITO, silver slurry etching and single sided board cutting.The screen displaying industry is very high to this location target required precision, and can in following process, can not be worn or situation such as occurrence positions skew, can improve the product yield so greatly;
The main mode through printing of conventional positioning mark mark pastes the surface of glass with cross mark or other pattern, and this mark mark accounts for dominant position all the time in application market; Along with the change that the touch screen industry is processed mode, glass is in printing, after the groove; Need carry out in flow processs such as tempering; Phenomenons such as wearing and tearing or offset take place in the mark mark that can cause like this being printed on glass surface, and this brings problem can for the follow-up operation of processing, and directly has influence on the finished product rate.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of not easy to wear, skew and the accurate Ultra-Violet Laser of the mark position devices and methods therefor at the transparent material inner marker is provided.
The objective of the invention is to realize like this: a kind of Ultra-Violet Laser is at the device of transparent material inner marker; Said device includes laser instrument; The laser that said laser instrument sends gets into scanning galvanometer behind optical gate and beam expanding lens; Be positioned at the workpiece to be marked on the article carrying platform through the laser directive that penetrates behind the scanning galvanometer, and the vacuum absorption device that workpiece to be marked is installed on the article carrying platform is adsorbed.
A kind of Ultra-Violet Laser of the present invention is at the device of transparent material inner marker, and the light path between said beam expanding lens and the scanning galvanometer is provided with completely reflecting mirror one and completely reflecting mirror two, and the even light path of reflecting surface of completely reflecting mirror one and completely reflecting mirror two is 45 °.
A kind of Ultra-Violet Laser of the present invention is equipped with CD system at the device of transparent material inner marker on the said scanning galvanometer, and the to be marked workpiece of the camera lens of CD system on the article carrying platform.
A kind of Ultra-Violet Laser of the present invention is at the device of transparent material inner marker, and said laser instrument is the high-frequency short-pulse laser.
A kind of Ultra-Violet Laser of the present invention is at the device of transparent material inner marker, and the optical maser wavelength that said laser instrument sends is 266 ~ 355nm, and pulsewidth is 1 ~ 20ns, and frequency is 10 ~ 200KHz.
A kind of Ultra-Violet Laser of the present invention is in the method for transparent material inner marker, and said method includes following steps:
Step 1: workpiece to be marked is placed on the article carrying platform, and the startup vacuum absorption device is treated mark workpieces and is adsorbed fixing;
Step 2: the laser that laser instrument sends carries out the etching marking operation with the inside that focus focuses on workpiece to be marked behind optical gate, beam expanding lens and scanning galvanometer.
Compared with prior art, the invention has the beneficial effects as follows:
Utilize laser to make mark be positioned at glass inside in the method for glass internal ablation mark; The glass surface of having avoided traditional ink printing to bring pollutes; Secondly glass is inner to be formed because mark is marked at; Can be because of not the coming off or offset of wearing and tearing or the mark mark that brings of secondary tempering, this has improved micro-machined precision greatly, thereby promotes the product yield; Have noncontact, nonpollution environment, manageable characteristics owing to laser simultaneously, so the precision of its mark is better, labeling effciency is also higher.
