Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment is only not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the amendment of the various equivalent form of values of the present invention.
Refer to shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, tablet medicament of the present invention lacks grain checking system, and wherein, powder is packaged into bottle and comprises motor and rotating disk 1, and 1, one through hole of output shaft connection rotating disk of motor can only hold a powder to be passed through.The below of rotating disk 1 is provided with funnel 4, and the through hole of rotating disk 1 connects the entrance of funnel 4, the outlet of funnel 4 be arranged on medicine bottle 5 directly over.There are how many through holes just can hold how many powders and pass through, thereby can control the quantity of powder in medicine bottle.Around the center of circle of rotating disk, on rotating disk, be provided with multiple via regions, each via regions has the through hole of fixed qty.In the turntable rotation formula powder charge process of pharmaceutical factory, powder is taken away by the through hole on rotating disk, arrives specific breach and drains in medicine bottle, thereby complete installing additional of one bottle of medicine.Therefore to detect this bottle of medicine and whether lack grain, must, before powder arrives and leaks under specific breach, complete the detection of taking pictures.
Synchronous coding device is to micro controller system according to real-time angle signal is provided, and micro controller system is according to this synchronizing signal, and control light source, camera exposure are taken pictures, and complete powder image acquisition.After image taking completes, detect software present image is carried out to analyzing and processing, and send in time result to micro controller system by RS232, micro controller system, according to current result, is controlled tonic device and is lacked grain tonic.
The present invention adopts " camera+PC image processing software " detecting pattern (PC-BASE), has filled up this detection field blank.
Checking system comprises industrial computer, micro controller system, detecting device 2 and tonic device 3, and detecting device 2 comprises camera and synchronous coding device, and synchronous coding device is arranged on motor, and synchronous coding device connects camera.Camera be arranged on rotating disk 1 directly over, camera connects industrial computer, industrial computer connects tonic device 2.
Refer to shown in Fig. 3 and Fig. 4, tonic device 3 involving vibrations devices 32 and helix oscillating plate 31, helix oscillating plate 31 connects oscillatory system 32, and oscillatory system 32 connects industrial computer.The exit of helix oscillating plate 31 is provided with medicine discharging opening 33, and medicine discharging opening 33 is arranged on the entrance of funnel 4.Preferably, oscillatory system 32 is electromagnetic vibration generator system.Wherein, also comprise annunciator, industrial computer connects annunciator.Also comprise LED light source, synchronous coding device connects LED light source.Also comprise micro controller system, synchronous coding device connects camera by micro controller system, and industrial computer connects annunciator by micro controller system, and synchronous coding device connects LED light source by micro controller system.
The invention also discloses the image-recognizing method that a kind of tablet medicament lacks grain checking system, adopt tablet medicament as above to lack grain checking system, comprise the following steps:
(1), first shape, size and the position of qualified tablet image are stored;
(2), Real-time Collection tablet image in production process,
(3) the tablet image, step (2) being obtained converts gray level image to;
(4), step (2) is obtained to greyscale image transitions and become bianry image;
