At present, online defective hole pick-up unit adopts photoelectricity transformation principle mostly, at sheet material upper surface installation and measuring light source, the sheet material lower surface is installed the photelectric receiver that is made of photomultiplier etc., to be converted into electric signal by the light signal that the defective hole transmission is come, by signal acquisition and processing apparatus these signals are gathered and handled again, thus the position of definite sheet material defective hole.
Interference for fear of surround lighting, the limit portion defective hole pick-up unit of some manufacturers' productions has all adopted the fixed frequency modulated light plate of limit portion both at home and abroad, the frequency modulated light plate is fixed on the erecting frame before production, sheet material allows to occur the sideslip of certain distance in process of production, bigger detection blind area has been caused in the position that the erecting frame of this moment and frequency modulated light plate can not be adjusted the frequency modulated light plate according to the distance of sheet material sideslip.
Summary of the invention
The object of the present invention is to provide a kind of sheet material limit portion defective hole pick-up unit,, sheet material limit portion defective hole can be detected the blind area and effectively be controlled in the millimeter level scope, provide quality assurance for producing high-quality sheet material by using this defective hole pick-up unit.
The present invention is achieved in that a kind of sheet material limit portion defective hole pick-up unit, comprise light source, light receiving unit, the frequency modulated light plate, " C " type frame, signal picker and computing machine, described light source and light receiving unit are installed in two ends of " C " type frame respectively, the frequency modulated light plate has two and is installed on " C " type frame, the frequency modulated light plate is between light source and light receiving unit, two blocks of frequency modulated light plates are close to the workplace of light source and light receiving unit respectively, the signal output part of described light receiving unit links to each other with the signal input part of signal picker, the signal picker output terminal links to each other with input end and computer, the signal output part of computing machine links to each other with the signal input part of basic servo motion unit, the output terminal of servo motion unit, basis links to each other with " C " type frame by leading screw, and leading screw promotes " C " type frame and laterally moves.
On described " C " type frame transversal driving mechanism is housed also, described frequency modulated light plate links to each other with transversal driving mechanism.
Described transversal driving mechanism comprises limit portion detecting sensor, motor drive controller and stepper motor, limit portion detecting sensor, motor drive controller, stepper motor and the frequency modulated light plate is in sequential series is connected.
The present invention has realized twice track and localization to sheet material limit portion by using basic servo motion unit and transversal driving mechanism.A track and localization: the logistics computing machine is sent to computing machine with next coiled strip width information, if bigger variation takes place in the last volume strip width, the strip width information that computing machine sends according to the logistics computing machine, sending controling instruction is to basic servo motion unit, servo motion unit, basis drives " C " type frame by leading screw, and " C " type frame moves to band limit portion with light source, light receiving unit and frequency modulated light plate.The secondary track and localization: limit portion detecting sensor passes to motor drive controller with detected sheet material limit portion information, motor drive controller judges whether the frequency modulated light plate is in the position of detection blind area less than 1mm, if the detected blind area of frequency modulated light plate is greater than 1mm, then drive motor drives the motion of frequency modulated light plate, rests in the position of blind area less than 1mm until the frequency modulated light plate.And be implemented under the very little detection blind area, shelves block and are radiated at band limit portion light in addition.Can accurately detect the defective hole that exists on the sheet material detecting under the situation of blind area less than 1mm by twice track and localization the present invention, effectively guarantee board quality.
Description of drawings
Fig. 1 is the structural representation of sheet material of the present invention limit portion defective hole pick-up unit.
Among the figure: 1 light source, 2 light receiving units, 3 frequency modulated light plates, 4 " C " type frame, 5 basic servo motion unit, 6 signal pickers, 7 computing machines.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, a kind of sheet material limit portion defective hole pick-up unit, comprise light source 1, light receiving unit 2, frequency modulated light plate 3, " C " type frame 4, signal picker 6 and computing machine 7, described light source 1 and light receiving unit 2 are installed in two ends of " C " type frame 4 respectively, frequency modulated light plate 3 has two and is installed on " C " type frame 4, frequency modulated light plate 3 is between light source 1 and light receiving unit 2, two blocks of frequency modulated light plates 3 are close to the workplace of light source 1 and light receiving unit 2 respectively, the signal output part of described light receiving unit 2 links to each other with the signal input part of signal picker 6, signal picker 6 output terminals link to each other with the input end of computing machine 7, the signal output part of computing machine 7 links to each other with the signal input part of basic servo motion unit 5, the output terminal of servo motion unit, basis 5 links to each other with " C " type frame 4 by leading screw, and leading screw promotes " C " type frame 4 and laterally moves.On described " C " type frame 4 transversal driving mechanism is housed also, described frequency modulated light plate 3 links to each other with transversal driving mechanism.Described transversal driving mechanism comprises limit portion detecting sensor, motor drive controller and stepper motor, limit portion detecting sensor, motor drive controller, stepper motor and 3 in sequential series connections of frequency modulated light plate.
