無接觸激光測量技術(shù)在橡膠工業(yè)中的應(yīng)用
Tread measurement
The entire contour of a tread can be measured by two traversing laser sensors (above and below the material). The measurements are possible for both car and lorry treads. The measured profile is compared to a master profile stored in the computer and monitored with respect to given tolerances. Logging and graphic display of the tread is possible. Measuring systems for offline and online measurement are available.
胎紋測量
整個胎紋的輪廓可由兩個分別安裝于被測產(chǎn)品的上方和下方的激光傳感器進(jìn)行測量。這種測量對驕車和卡車胎紋均適用。所測量胎紋輪廓與儲存在計(jì)算機(jī)中的標(biāo)準(zhǔn)紋型進(jìn)行比較,按給定公差進(jìn)行監(jiān)控,并以數(shù)據(jù)和圖形的形式進(jìn)行顯示,在線或線下測量系統(tǒng)均可實(shí)現(xiàn)。
Profile measurement
It is possible to measure profile surfaces by combining an OPTIMESS laser sensor with a drive unit, e.g. linear unit or robot. This may be profiles of tire surfaces and technical products of the rubber industry such as the profile of single or multiple V-belts or toothed belts. The possibility of adapting the laser point diameter individually to sensors in OPTIMESS as well as the ability to measure on inclined surfaces up to about 80° open up new possibilities for online quality inspection.
外形測量
將一個OPITMESS激光傳感器與一個驅(qū)動裝置(如線性運(yùn)行裝置或機(jī)器人)聯(lián)接,可以測量外形輪廓表面。外形可以是輪胎表面或者橡膠工業(yè)的技術(shù)產(chǎn)品,比如單層或多層V-形帶、齒形帶等。激光點(diǎn)直徑可根據(jù)OPTIMESS傳感器進(jìn)行單獨(dú)調(diào)整,表面測量傾角甚至可以接近80°,為在線質(zhì)量監(jiān)測開辟新的應(yīng)用。
Thickness measurement
Two sensor layouts are available basically for the thickness measurement. One sensor is used for the reference measurement on a roller. The product runs over a roller which is used as a basis for the zero point. The subsequent measurement on the product is set off against the zero point and output as a thickness. In the thickness measurement with two sensors the product runs between two sensors, one above, one below the material. The difference between the two sensor values gives the thickness. The advantage of this measuring set-up is that the product can move vertically to the direction of travel without causing measuring errors. Air-cooled OPTIMESS sensors are available for measuring warm materials. Traversing thickness measuring systems are available in addition to the stationary thickness measurement with separate measuring tracks.
厚度測量
布置兩個傳感器是進(jìn)行厚度測量的基礎(chǔ)。首先為一個滾筒指定原點(diǎn),產(chǎn)品在滾筒上移動,與轉(zhuǎn)軸接觸的一面被作為零點(diǎn),接下來的測量是相對于零點(diǎn)測出一個厚度值。另一種厚度測量,產(chǎn)品在位于其上方和下方的兩個傳感器之間移動,兩個傳感器測出的距離差得出產(chǎn)品的厚度值,這種測量裝置的優(yōu)點(diǎn)是產(chǎn)品可以在傳送時上下振動時不會發(fā)生測量誤差??諝饫鋮s的OPTIMESS傳感器可以對高溫材料進(jìn)行測量。穿梭厚度測量系統(tǒng)可以實(shí)現(xiàn)不同軌道的固定厚度測量。
Width measurement
Two OPTILINE systems are used respectively for the width measurement. The width is measured by the shadow measurement method which means that the laser generates a parallel band of light which is projected onto a detector. The continuous rubber band shades part of the laser beam from the detector. The position of this shadow is evaluated and output as a width by calculating the difference of both systems. No additional light source Is required for the measurements.
寬度測量
兩個OPTILINE系統(tǒng)被很好的用于寬度測量。寬度測量采用影子測量法,操作原理是激光將一束平行光束投射到一個接收器上,而連續(xù)運(yùn)動的橡膠帶會遮檔部分光束,評測投影的位置,計(jì)算兩個系統(tǒng)的差異而輸出寬度,測量中不需要附屬光源。
Overlap measurement
It is very important for the manufacturing of tires whether two layers of rubber overlap, touch or form a gap. OPTIMESS sensors are suitable for quick detection of measured value jumps or overlaps due to their high measuring frequency of up to 50 kHz. Edge Jumps can therefore be detected with a high reproducibility in connection with a distance measuring system.
重疊測量
對于輪胎制造業(yè),測量兩層橡膠的重疊、接觸、或者存在間隙,都非常重要。OPTI MESS傳感器可快速檢測以上指標(biāo),測量頻率高達(dá)50KHz。因此,與一個距離測量系統(tǒng)連接,可以快速再現(xiàn)邊跳狀況。
Expansion measurement
The non-contact scanning of the tire surface enables measurement of the expansion of a tire at maximum speeds. This can be done both on the test stand and directly on the vehicle.
膨脹測量
無接觸輪胎表面掃描可測量輪胎在高速下的膨賬量,它既可用于標(biāo)準(zhǔn)測試也可直接用于車輛檢測。
Non-concentricity measurement
It is possible to measure the vibration and wobble up to maximum speeds using the special OPTILINE system. Here too up to 20,000 measurements/s are possible. Special OPTIMESS laser sensors are being used in test machines made by Seichter as an alternative to capacitive measurement for non-concentricity and dents.
偏心率測量
運(yùn)用特殊的OPTILINE系統(tǒng)測量輪胎在最高速度下的擺動性及振動性,可達(dá)到20000次/秒的測量速度。特殊OPTI MESS激光傳感器被用于由SEICHTER公司制造的機(jī)器中,代替電容測試,用于偏心率測量。
Deformation measurement
OPTIMESS sensors allow non-contact measurement of tire deformations under different test conditions such as wheel load, track and king pin angle. These may be measurements on the roller test stand but also measurements on the test vehicle - due to the small size of the sensors. An extreme application here is the deformation measurement inside a lorry tire. A special OPTIMESS sensor is mounted on the rim inside the tire and measures the contact surface of the tire.
變形測試
OPTI MESS傳感器可實(shí)現(xiàn)在不同測試條件下形變測試,比如車輪承載,軌跡和景斌傾角(汽車轉(zhuǎn)向幾何學(xué)角度)等,它既可在滾筒架上測量也可在車輛檢測中使用——由于傳感器體積小,它還可以在卡車輪胎內(nèi)中測量形變。特型OPTIMESS傳感器被裝于輪胎內(nèi)側(cè)輪沿上用于測量輪胎的接觸面。
Test drive/Texture measurement
The laser is a virtually unrivalled measuring instrument for the non-contact measurement of the distance between vehicle and road to characterize the road handling. In the field of tire test drives the laser offers the possibility of scanning the tire surface on a test machine, i.e. the whole tire surface is measured according to specified drive cycles to examine and document saw tooth formation, erosion, etc. in addition to normal wear. The laser offers other application possibilities In the deformation measurement of the tire when the vehicle is in motion and the measurement of road surfaces as an important parameter in the development of tires with respect to aquaplaning and noise behavior.
試駕/材質(zhì)測量
實(shí)際在車輛與道路的間距、道路路況的無接觸測量,激光則獨(dú)占鰲頭。在輪胎測試駕駛中,測試機(jī)用激光掃描輪胎表面:包括在特定行駛周期內(nèi)檢測記錄鋸齒形變,侵蝕等,加上正常的磨損等全部輪胎表面數(shù)據(jù)。激光技術(shù)測量輪胎在車輛運(yùn)動過程中的形變,路況,也為輪胎打滑及噪聲研究提供重要參數(shù)。
