Su vis dažniau pagreitintas procesas automobilis intelektas ir Internetizacija, the prietaisų skydelis, automobilis planšetinis kompiuteris, ir kiti transporto priemonėje ekranai komponuoti dideli ekranai, keli ekranai, 3D curved ekranai, ir kita transporto priemonėje ekranai servizai as įėjimai į the automobile, kuris buvo integruotas su funkcijomis of car networking, assisted driving, audio-visual and audio-visual, etc. , and the completion of sensing, decision-making, application, action, and execution through voice, touch, gestures, images and other means, bring a wonderful human-machine interaction experience, and nuolat adding to the intelligent driving It bring a wonderful human-computer interaction experience, and continuously empowers and adds points to the intelligent driving, hip and playful attributes.
In the realization of these functions, the importance of in-vehicle display is self-obvious; and in the outermost layer of the in-vehicle display, it is necessary to fit a layer of glass cover plate, which most serves to protect the display, with the functions of anti-impact, secret-crack-resistant, oil-resistant, tape-resistant, enhanc enhanced light transmittance. The rapid development of the car display market has also given kilimas į automobilis stiklas dangtis rinka.
As automobiliai tampa daugiau ir daugiau išmanus ir moka daugiau dėmesio į the driving experience, not only the number of in-vehicle displays increase, but also size and shape of the display is more and diversified; which has more demand for glass cover cutting applications, but also put forward higher requirements for cutting speed and quality. Automobilis stiklas dangtis is a sluoksnis iš itin plonas stiklas, neprivaloma medžiagos are paprastai sustiprintas natrio kalkės stiklas ir borosilikatas stiklas, the storis can be as low as tens of microns; and realizuoti the precision cutting of įvairios shapes of such a thin and hard material is neabejotinai labai sudėtinga.
Tradicinis Pjovimas Metodai
Tradicinis mechaninis pjovimas metodai daugiausia naudojimas peilis pjovimas, CNC cutting, etc. These are contact cutting, and their main drawback is that the mechanical stress applied can easily cause chipping, or may cause the glass to expand from small cracks to large cracks along the low-strength areas because of the stress. In addition, the cutting accuracy and overall cutting efficiency of mechanical cutting are relatively low.
Su the booming automotive intelligence industry, it is clear that more efficient and smarter production techniques are need for on-board glass cover. New cutting technology, to be able to achieve both fast enough cutting speed, but also to achieve high enough cutting accuracy, but also to ensure good enough cutting edge quality, often requiring chipping between tens and hundreds of microns; laser cutting solutions came into being.
Pikosekundas lazeris pjovimas programa
Palyginti su tradicinis kontaktas mechaninis pjovimas, lazeris pjovimas is a nekontaktinis procesas, kuris gali išspręsti the traditional pjovimas procesas dėl į mechaninis stresas sukeltas pagal a įvairovė problemos.
Šis lazeris pjovimas sprendimas a pikosekundė itin greitas lazeris + Bessel pjovimas galvutė, ir the light source is a 50}W infrared picosecond laser with a pulse width of about 10ps. The ultra-high peak power of the picosecond pulse can realize high-efficiency cutting and cold processing, and the glass cover plate with a storio of 0.3mm, can be cut and shaped at one time with high precision and good kokybė (žr. Paveikslas 1).
The main advantage of using picosecond ultra-short pulse width lasers is that the energy can be inject into the processed area of the glass surface in a very short period of time, and the energy transfer is completed (most of the energy is transferred to the electrons, and a small portion of the energy is transferred to the crystal lattice) before the thermal effect happens, result in the glass going directly from kieta būsena to the gas state, and the removal of the glass by evaporation. Todėl, this "cold process" has minimal effect on the cutting surface of hard and trapus stiklas.
When laser cutting, the laser beam is focused to form a very small spot, and the focused spot diameter is in the micron range, resulting in in labai power density at the focal point. When cutting arcs or right angles and other shaped cuts, the minimum cutting line width that can be realized is {{{0}}}.1 mm, the chipping is less than 0.1 mm% 2c ir the overall pjovimas edge tekstūra is good.
In papildymas, šis pjovimas sprendimas is įrengtas su an automatiniu išlyginimu kamera ir vizija objektyvas, su a pozicionavimu tikslumu of ±{{{0}}.002mm, kuris gali tiksliai identifikuoti įvairūs taikiniai taškai ir automatiškai kompensuoti už juos, ir gali pasiekti a pjovimas tikslumas iš ±0.02mm.
Kai pjovimas, the vision system can quick capture and identify the edges and characteristic points of the glass, taigi realizavimas fast identification, tikslus pozicionavimas, ir tikslus pjovimas, užtikrinimas the consistency of product cutting, which not only improves the production efficiency but also reduces the influence of human factors on the cutting accuracy.
Šis pikosekundės lazeris pjovimas sprendimas is tinkamas greitas, didelio tikslumo neardomasis atviras-pjovimas išskirtų įvairių išlenktų formų, dešiniųjų kampų, ir kitų formų reikalingų for in-vehicle displays (žr. Fig. 2), which can solve the industry's small batch, multi-species, multi-batch, different shapes of in-vehicle glass cutting problems.
In the field of glass processing, the golden combination of picosecond laser + Bessel cutting head is gaining popularity. From high-end panel glass, and photovoltaic glass to Low-E architectural glass, and even the manufacture of precision optical components, this glass-cutting solution has shown great potential and value. In the future, with the further development and optimization of the technology, picosecond laser + Bessel cutting technology is expected to be applied in more fields, and realize more opportunities in industrial manufacturing and scientific research and other fields!
