Description
Technical field
The present invention relates to a kind of equipment location and installation measuring system, relate in particular to a kind of awning film production line die head location and installation measuring system based on machine vision.
Background technology
Along with the influence of global greenhouse effect, global extreme weather is more and more frequent, and is great to the growth effect of crops, and the appearance of awning film, changed the dependence situation of crops greatly, made crops can be subjected to climatic influences less as far as possible, guaranteed the stability of output for outside weather.The important assurance that present awning film has become crop growth, increases production and increased income.Awning film is for improving China's level of agricultural production, and it is significant to improve the people's livelihood.The thickness evenness of awning film is an important indicator weighing the awning film quality, also directly determine the transmittance of light etc. is directly influenced the index of plant growth the service life that thickness had both directly influenced film, keep cold season temperature of shed also to have a direct impact.Thereby must guarantee the thickness evenness of awning film.In awning film is produced, influence that in numerous factors of thickness evenness individual key factor to be arranged be exactly the installation orientation problem of film head.The film head is installed the thickness homogeneity that the deviation of locating will directly influence product.
Different based on the actual application requirements, the film thickness of producing is also different, domestic hot house film is according to southern and northern weather difference, general production finger gauge lattice distribution is at 0.06mm-0.12mm, this is the overall manufacturing specification limit, product for certain concrete specification, film such as 0.08mm thickness, error range requires in 0.01mm, such required precision, the installation of mould location be unusual key just, and deviation is arranged slightly, will cause very large influence, the plastic foil production mould is made up of inner mold and outer mold.Inner membrance is a solid cylinder, and outer mold is a cylinder, and the size of interior outer mold is also different according to the production capacity difference, has two meters to diameter from tens centimeters of diameters more, and interior outer mold connects by bolted.And the gap between the inner mold according to the production capacity different distributions in the scope from about 1mm-3mm, for the film thickness that guarantees to produce even, must guarantee the concentric of outer mold and inner mold strictness, otherwise will cause the uneven film thickness produced, if the installation decentraction, Yi Bian must cause too thickly, and another side is too thin, even waste product appears because some zone is too thin, cause heavy economic losses.
At present, the installation location of film head is still in the manual detection mode, concrete grammar is for earlier being placed in outer mold with instruments such as cranes inner mold earlier, according to bolt hole elder generation coarse positioning, adopt the feeler gauge clearance gauge to fill in a mouthful die clearance again, the workman measures its gap width, according to the situation in gap, adjust repeatedly, concentric up to interior outer mold, such installation method installation accuracy mainly relies on workman's installation experience, depend on for the measurement in gap and workman's reading to have error in reading, same gap numerical value, the data that different people reads just may be different, must cause position error big like this, often will regulate repeatedly repeatedly according to the deviation situation of actual film goods when producing and just can reach production requirement, waste time and energy, waste is serious, causes the increase of production cost.
In the prior art, CN101958154A discloses a kind of platform automatic horizontal control system based on machine vision, its by to camera collection to image analyze, judge, platform is carried out automatic leveling; But its frame for movement more complicated is easy to operate and fault rate is high, and it does not have human-computer interaction device yet simultaneously, can't be according to the expectation numerical value and the contrast number of on-the-spot actual needs Adjustment System.
