Detailed description of the invention
1 to 4 pair of the specific embodiment of the present invention is described further by reference to the accompanying drawings:
In FIG, the entirety that device is responsible for by single-chip microcomputer controls, and comprises signal in gathering line array image sensor, judges glue heap surplus, and charactron communication etc.Light source control interface driver laser diode is launched, and feeds back according to light intensity, thus ensures the stability of light source.Laser diode launches laser, after collector lens focuses on, vertical irradiation is to the surface of tested Jiao Dui, and form very little hot spot, hot spot is imaged onto on line scan image sensor through optical lens, when glue stack height is different, the position dropped on after hot spot imaging on line scan image sensor is also different.Line scan image sensor converts the optical signal received to the signal of telecommunication and send to single-chip microcomputer after amplifying, single-chip microcomputer is processed by image processing techniques the view data after amplifying and calculates hot spot and is positioned at position on line scan image sensor, the storage of Jiao Dui is judged according to this result of calculation, when glue volume of cargo in storage is lower than setting benchmark, single-chip microcomputer outwards sends alarm signal.Display tube communication interface is for connecting charactron and film key, and charactron is for showing reference position and the physical location of Jiao Dui, and film key is for arranging the reference position of Jiao Dui.
As shown in Figure 2, laser diode 7, collector lens 11, optical lens 2 and line scan image sensor 3 press certain angle installation.The laser direction that laser diode 7 is launched is perpendicular to the optical axis of collector lens 11, and in angle of 45 degrees, line scan image sensor 3 is vertical with laser direction for optical lens 2 and laser direction.Laser impinges perpendicularly on the surface of tested Jiao Dui after collector lens 11 focuses on, and form very little hot spot, hot spot is imaged onto on line scan image sensor 3 through optical lens 2.When glue heap is sufficient, hot spot is positioned at A point on Jiao Dui, and now, hot spot images in B point on the image sensor; When glue stack height reduces, hot spot is positioned at the A' point on Jiao Dui, and now, hot spot images in B' point on the image sensor.Visible, the picture point of hot spot on line scan image sensor can change according to the change of Jiao Dui position.We can arrange the reference position of a Jiao Dui, line scan image sensor has a corresponding reference position picture point, when on Programmable detection to line scan image sensor, the position of picture point exceedes reference position picture point, just can judge that plastic emitting heap is lower than reference position, program will send the not enough alarm signal of glue heap.In addition, the detection sensitivity of Jiao Dui can be changed by the adjustment focal length of optical lens and the pixel value of line scan image sensor.
In figure 3, the lower rubber roller 13 of rolling up and connecting machine contacts glue 14, and lower rubber roller is stained with glue and contacts with upper glue roller 12, and upper glue roller 12 forms Jiao Dui.Line scan image sensor converts the optical signal received to the signal of telecommunication and sends to single-chip microcomputer to carry out image procossing after amplifying.First the view data delivered in single-chip microcomputer is carried out denoising by the image processing program in the present invention, and the background in removal of images and noise, on the impact detected, give prominence to the useful information in image.Next step, analyze the peak value of recognition image, determine the center pixel position of image, find this pixel to be arranged in the position of line scan image sensor, compare the position relationship of this pixel and reference position picture point, and then judge the surplus of Jiao Dui.When detecting that glue volume of cargo in storage is not enough, single-chip microcomputer sends alarm signal.
In the diagram, be first welded on control panel 4 by charactron 5, control panel 4 is fixed on drain pan 1 by screw 9.Then, line scan image sensor 3, film key 6 and laser diode 7 and collector lens are connected with control panel 4 by connector, and are separately fixed in the special slot of drain pan 1.Again optical lens 2 is installed on drain pan 1 support.Then, windowpane 8 is fixed on drain pan 1 side panel.Finally, case top lid 10 and drain pan 1 are fixed together.Drain pan side panel is also provided with film key 6, handled easily human users.
Testing result of the present invention is only relevant with the facula position be irradiated on Jiao Dui, has nothing to do, accurately can detect the glue volume of cargo in storage of rolling up and connecting machine upper glue roller with surrounding environment light and hot spot brightness.
Certainly; more than illustrate and be only preferred embodiment of the present invention; the present invention is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the guidance of this description; made all equivalently to substitute, obvious variant, within the essential scope all dropping on this description, protection of the present invention ought to be subject to.
