Description

Tablet perforation detection system and control method thereof Technical Field The invention relates to the technical field of tablet perforation detection, in particular to a tablet perforation detection system and a control method thereof. Background In order to ensure that the tablet can be completely released after entering a human body so as to be absorbed by the human body, in the prior art, the tablet is coated with a semipermeable membrane (such as nifedipine tablet and the like) which cannot be penetrated by drug molecules, and then the semipermeable membrane and the tablet are penetrated by an opening device (such as a laser perforating device) to form micropores inside the tablet, so that after the tablet enters the human body, moisture inside the human body can permeate the semipermeable membrane, osmotic pressure difference can be generated inside and outside the tablet, and drug components are released from the micropores through pressure difference control, so that the full and stable absorption effect of the human body on the drug is ensured. However, due to the fact that the functions and parameters of the tablets to be perforated are different, the required perforation parameters are required to be set to be corresponding to different adaptation values, based on the fact that the perforation inside the tablets is required to be detected in real time after perforation inside the tablets is completed, so that hidden dangers such as cracks and cracking of the tablets cannot be caused in the perforation process while successful perforation is achieved, the storage time of the tablets and the effectiveness of the tablets are guaranteed, and meanwhile the full and stable absorption effect of a human body on the medicines can be effectively improved. In the prior art, aiming at the detection process of different tablet tapping parameters, a tablet is often sent to a detection position through a conveying device, an optical signal sent by a light source emission unit passes through an internal tapping of the tablet and is captured by an image acquisition unit, whether tapping parameters are qualified or not is determined according to the comparison of captured actual image parameters and standard tapping parameters, and the following defects and defects exist while the automatic pipeline operation of detection is ensured: 1) Because the unqualified types of the perforation parameter detection inside the tablet are more, when the perforation shape parameter detection is unqualified, the detection can be directly determined according to the optical signal image obtained by the image acquisition unit, for example, when the perforation is unsuccessful, the image acquisition unit cannot obtain the optical signal image, and when the perforation is incomplete, the image acquisition unit cannot obtain the complete optical signal image, so that the detection can be directly determined through image detection judgment without complex image processing technologies (such as denoising, contrast enhancement, edge sharpening processing and the like) and parameter calculation comparison processes, and the detection mode in the prior art needs to carry out the image processing and parameter calculation comparison on the image corresponding to the perforation parameter of each tablet and then judge, thereby increasing the image processing amount and the parameter calculation amount and reducing the detection efficiency; 2) Because of the multiple unqualified types of the inspection of the perforation parameters in the tablet, the unqualified reasons of the inspection of the perforation parameters in the tablet are various, and the incorrect setting of the perforation process parameters of the tablet (such as the fact that the laser emission power is too small to penetrate the tablet, the deviation of the laser emission position and the emission angle, the deviation of the transmission position and the like) is possible, and the problems in the inspection process are also possible, such as the fact that the selected perforation model is not matched with the perforation process of the tablet, or the transmission error of the transmission module or the position deviation caused by the start-stop process is caused, or the fact that the optical signal sent by the light source emission unit is not matched with the perforation requirement is also possible, so that the correction priority and the amplitude of the unqualified conditions of the inspection of the perforation parameters are different from each other, and the prior art cannot provide the corresponding effective correction amplitude and the corresponding priority of the unqualified conditions of the inspection of different perforation parameters. Based on this, a new solution is needed to solve the above-mentioned drawbacks and deficiencies of the prior art.
