Description

Technical Field

[0001] The present invention relates to the technical field of drug sub-packaging verification, and in particular to an intelligent verification system for sub-packaging drugs. Background Art

[0002] The drug subpackaging verification system is designed to cooperate with the subsequent inspection work of the automatic drug packaging machine. The existing subpackaging machines on the market do not have the ability to detect the number and model specifications of the drugs in the drug package. After the drug packaging is completed, the device is added to assist in identifying the accuracy of the drugs in the drug package. The camera station takes pictures to extract the outline of the items, and reads the drug information by identifying the QR code on the outer packaging of the drug bag. The collected outline is compared with the preset drug size of the system to ensure the accuracy of the verification work, because the drugs are not overlapped and the identification is correct.

[0003] The invention with publication number CN114279967A discloses a subpackaged drug verification device and method, wherein an image verification system is arranged on the conveying path of the conveying material system, and is used to obtain an image of the medicine bag, and based on a visual algorithm, verify whether the medicine in the medicine bag is consistent with the prescription according to the image; a human-computer interaction system is respectively connected to the conveying material system and the image verification system by signal, and is used to receive the drug information input by the user, and receive the device control operation input by the user to control the working state of the subpackaged drug verification device.

[0004] The invention of publication number CN117114038A discloses an automatic checking method and system for a medicine packaging machine, which is used to process and detect the packaged medicine bags on the conveying device of the packaging machine system. The packaged medicine bags are the final products after the packaging of the packaging machine system, that is, they are tested at the last link of the circulation of the medicine in the packaging machine instead of the middle link. The method of the present invention can avoid the possibility that the medicine packaging is inaccurate but cannot be checked due to problems in other drug circulation links.

[0005] However, the above-mentioned verification system for subpackaged drugs still has the following problems during actual use: although the identification system assists in reading the type and information of subpackaged drugs, due to differences in specifications and packaging sizes, the drugs in the subpackages are piled up on each other, which causes the identification code on the outside of the subpackage bag to be tilted or misplaced, making it difficult to quickly and efficiently adapt and read it through the verification system. At the same time, during the movement of the subpackage bag, the drugs inside the bag are constantly stacked and offset. Even if human intervention is timely, it will cause the identification code to be misplaced and difficult to identify, affecting the overall verification efficiency.

[0006] Therefore, we proposed an intelligent verification system for subpackaged drugs to solve the above problems. Summary of the invention

[0007] The purpose of the present invention is to provide an intelligent verification system for subpackaged medicines, in order to solve the problem that the existing identification system assists in reading the type and information of subpackaged medicines, but due to differences in specifications and packaging sizes, the medicines in the subpackages are piled up on each other, which causes the identification codes on the outside of the subpackage bags to be tilted or misplaced, making it difficult to quickly and efficiently adapt and read them through the verification system. At the same time, during the movement of the subpackage bags, the medicines inside them are constantly stacked and offset, and even timely human intervention will cause the identification codes to be misplaced and difficult to identify, affecting the overall verification efficiency.

[0011] Preferably, the width of the main conveyor belt is smaller than that of the auxiliary conveyor belt, and in the initial state, the main conveyor belt and the auxiliary conveyor belt do not fit each other, and the tightness of the fitting connection is assisted by a belt tensioning wheel on the inner wall of the main conveyor belt.

[0015] Preferably, a lifting stepper motor and a translation stepper motor are fixedly arranged on the front side of the auxiliary conveyor frame, and the output ends of the lifting stepper motor and the translation stepper motor are fixedly connected to the outer wall of the linkage horizontal plate, so that the lifting stepper motor and the translation stepper motor can drive the linkage horizontal plate and the linkage bracket, the scraper bag pressure plate, and the silicone scraper bag to move in the up and down directions and left and right directions, thereby achieving the effect of scraping and leveling the packaged medicine bags.

At the same time, the positioning pressure plate is used to ensure that the packaged medicine bags inside the camera module are positioned, so as to extract the outline of the product, and read the drug information by identifying the QR code on the outer packaging of the medicine bag.

[0017] Preferably, the transverse center axis of the auxiliary conveyor frame is parallel to the transverse center axis of the main conveyor frame, and the main conveyor belt inside the main conveyor frame and the auxiliary conveyor belt inside the auxiliary conveyor frame are in contact with each other, so as to convey the packaged medicine bags on the top surface of the auxiliary conveyor belt, so that the packaged medicine bags can be limited and leveled and subsequently scanned and identified.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the intelligent checking system for subpackaged medicines drives the subpackaged medicines to be conveyed by fitting and separating the main conveying belt and the auxiliary conveying belt, and at the same time, after the medicine bag pressing plate limits the subpackaged medicines, the silicone bag scraping sheet flattens the subpackaged medicines, and the positioning pressing plate inside the camera module positions them again, so that the camera module reads the identification code of the subpackaged medicines after the pressing and positioning, extracts the outline of the medicines, and reads the medicine information by identifying the QR code on the outer packaging of the medicine bag, so as to ensure the accuracy of the checking work. The specific contents are as follows: 1. The main conveyor belt engaged with the driving wheel is kept moving through the main pulley, and the lifting cam inside the lifting bracket rotates to move it to the top of the cam slot plates on the left and right sides of the main conveyor frame, so as to fit the auxiliary conveyor frame and the main conveyor frame 1 together. At the same time, the moving main conveyor belt drives the auxiliary conveyor belt fitted on the bottom to move synchronously, and the auxiliary conveyor belt is ensured to be stable through the driven wheels and auxiliary pulleys at the left and right ends.

[0019] The belt tensioner is closely connected to the main conveyor belt, and the belt tensioner ensures the tightness of the fit between the main conveyor belt and the auxiliary conveyor belt, so that the auxiliary conveyor belt can move with the main conveyor belt, and then the auxiliary conveyor belt drives the sub-packaged drugs on the top surface to move and transport.

[0020] 2. By separating the main conveyor frame from the auxiliary conveyor frame, the sub-packaged medicines are in a stationary state, and the flip motor drives the flip cam at the end of the output shaft to rotate, so that the driving shaft drives the medicine bag pressing plates installed at equal distances to rotate downward, so that the front end of the medicine bag pressing plates can resist and press against the packaging bags of the sub-packaged medicines to prevent displacement during the subsequent leveling process.

[0021] The lifting stepper motor drives the linkage horizontal plate to move downward, so that the scraper plate pressure plate and the silicone scraper plate installed by the linkage bracket can be lowered to the required flat height, and then the translation stepper motor drives the silicone scraper plate to move back and forth to the front and rear sides. At the same time, the silicone scraper plate scrapes the sub-packaged medicines that are attached to each other at the bottom, so that the identification code of the sub-packaged medicines is in a horizontal state for subsequent identification.

[0022] 3. The subpackaged medicines are transported again through the auxiliary conveyor belt. During this process, the driving shaft rotates again, thereby driving the positioning plate on the right end to press on the top surface of the subpackaged medicines, so that the camera module reads the identification code of the subpackaged medicines after pressing and positioning, extracts the outline of the medicines, and reads the medicine information by identifying the QR code on the outer packaging of the medicine bag. The collected outline is compared with the preset medicine size of the system to ensure the accuracy of the verification work. BRIEF DESCRIPTION OF THE DRAWINGS
