The device has the advantages that the error precision of the thickness and the homogeneity of the aluminized film is improved from plus or minus 10 percent to plus or minus 3 percent, thereby satisfying the requirement of the product quality.
Description
Technical field
The utility model relates to a kind of surface measurements bed device, relates in particular to a kind of device of measuring micro-coating thickness change of aluminizing thin film.
Background technology
The physical characteristics of plastic sheeting itself and its transparency have determined its wood property (particularly transparent mylar, English be called for short " PET ") to possess seldom barrier property.
Therefore by plating layer of metal material---aluminium uniformly in polyester film surface, produce after the good structure curing through 24 hours metallic aluminium molecules later on, can make this product possess very strong barrier property, it can intercept sunshine (function that has reflection ray simultaneously) antiultraviolet.Be the introduction of several films below:
A, sun blow-out disc: well-known, the auto industry of our country is flourish now, therefore, used blow-out disc market also is that supply falls short of demand, market demand is very big, and produce in the process of vehicle explosion-proof film, vacuum aluminum-coated is vital technology together wherein, because the main effect of vehicle explosion-proof film has three aspect: A, prevents in the solar ultraviolet irradiation car; B, heat insulating function; C, explosion prevention function.And if the uneven words of aluminium coated can cause following some important quality problems in the vacuum aluminum-coated process of film:
(1) bad as aluminium lamination uniformity coefficient in the process of aluminizing, can cause the function of one side ultraviolet radiation preventing fine, and another side is very poor, the left side is good later on perhaps to stick film with a vehicle window, and the right is bad, and vice versa.
(2) the inhomogeneous meeting of aluminium lamination causes very big aberration, color was dark on one side after a car posted, light on one side, that is that the car owner is definitely unacceptable, because attractive in appearance also is that the car owner pastes one of key factor of solar film, therefore the aluminium lamination uniformity coefficient of solar film is required to need very evenly could satisfy the requirement of final products.
(3) the inhomogeneous non-constant of effect of heat insulation that also can cause of aluminium lamination, on one side heat-proof quality fine, and the another side heat insulating function is very poor.
So, more than three kinds of quality reasons be exactly when producing because of aluminizing, aluminum layer thickness is inhomogeneous to be caused.
B, electronic shield film: electronics industry is as the mainstay industry of 21st century, and its effect is increasing, as " patron saint " of electronic product---and the electronic shield packaging bag then is a requisite product in the electronic product.The electronic shield packaging film mainly designs production according to physical principle faraday electricity cage principle so, and vacuum aluminum-coated exactly be exactly to solve a best process means of this principle, if the PET film is through mainly having formed the effect of the following aspects after vacuum aluminum-coated and aluminum plating process is inhomogeneous also can cause following problem:
(1) the PET film is through after vacuum aluminum-coated, and the surface has just formed metal level, then also just formed conductive network, if but common vacuum aluminum-coated then: (1) has influenced the visuality of packing; (2) shielding properties does not reach and requires 1 minute<46dB electromagnetic wave.Therefore, if vacuum aluminum-coated in uneven thickness, just can't guarantee shielding properties at all.
(2) if vacuum aluminum-coated uniformity coefficient is bad, will cause the aluminium lamination of PET film, Yi Bian very transparent, translucent on one side, according to the principle requirement of faraday electricity cage shielding, the surface of product just has blind spot so, cause hole region, just can't guarantee the shielding properties of product.
Producing the best manufacturer of vacuum aluminum-plating equipment in the world now mainly contains: internationally famous companies such as the precious photoelectricity of German Lay company limited, German Applied Materials Inc, Britain General Corporation (GVE), Italian Galileo company.Usually the thickness and the uniformity coefficient that detect aluminium coated all are the on-line measuring devices of dependence equipment itself---the pick-up unit of eddy current is done online detection, two kinds of detection methods of vertical measurement and cross measure are arranged, be to be reflected on the computing machine and to make calculating, finally draw the data of aluminum layer thickness and uniformity coefficient by data with each check point.Its cardinal principle is the aluminum layer thickness that how much detects by the magnitude of current that detects aluminium lamination, and the general error rate that produces of this detection method is usually more than ± 10%.And when particularly producing sun blow-out disc or electronic shield film because aluminum layer thickness is very thin, the magnitude of current seldom, if the product aluminum layer thickness of producing is less than 200A, its detection error rate is bigger, will reach ± 15%-20% between.
Except said method, now a lot of factories use another method of operating usually, are attached on the equipment view window by the sample with required production exactly, observe producing with technician's eyes.Just think, the speed of production of general import equipment all is more than 600 meters/minute, observes and along with the variation of light, angle, everyone eye difference with people's eyes, so the product of producing all can't be guaranteed aluminum layer thickness and uniformity coefficient no matter be vertically or laterally.Bad during fashion, at all can't be from solving the problem on the product quality in essence.
Summary of the invention
The utility model technical issues that need to address have provided a kind of device of on-line determination micro-coating thickness change of aluminizing thin film, are intended to solve the above problems.
