Description

Technical Field

[0001] The invention relates to the technical field of drug detection, and in particular to a finished product detection device for a pesticide granule coating production line. Background Art

[0002] Tablet coating is a common method of tablet processing, which can prevent moisture, light, isolate air, increase drug stability, cover up bad smells, reduce irritation, control drug release sites, and control drug diffusion and release speed. However, due to production process problems, the coating may be damaged, cracked, uneven, etc., thus affecting the use effect of the tablets.

[0003] In order to accurately identify tablets with defective coatings, China with application number CN202022926777.4 discloses a tablet coating detection device, including: a transparent carrier for carrying tablets to be detected; one or more ultraviolet cameras for photographing the area where the transparent carrier is located; an image processing unit, which is connected to the ultraviolet camera in communication to receive the ultraviolet image collected by the ultraviolet camera, identifies defective coated tablets according to the ultraviolet image, and determines the coordinates of the defective coated tablets; a picking unit, which is connected to the image processing unit in communication to pick up defective coated tablets according to the coordinates of the defective coated tablets. Through the above technical solution, the effect of batch detection of tablet coating quality through ultraviolet images can be achieved.

[0061] Wherein, the mobile unit includes a first driving wheel 71 and a second driving wheel 72 arranged on the positioning seat 61, a driving belt 73 is arranged on the first driving wheel 71 and the second driving wheel 72, and a first driving motor 74 connected to the first driving wheel 71 is fixedly arranged on the positioning seat 61, and the driving belt 73 is moved under the drive of the first driving motor 74; a travel seat 75 is slidably arranged on the positioning seat 61, and the travel seat 75 is driven by the driving belt 73 to slide.

[0065] It should be noted that the UV camera is a device that collects ultraviolet light to form an image, including a lens, an ultraviolet filter film and an image sensor. The UV camera can obtain a monochrome image corresponding to the object, such as a grayscale image, according to the intensity of the ultraviolet light emitted or reflected by the object, in which the grayscale value of each pixel corresponds to the intensity of the ultraviolet light emitted or reflected at the corresponding position of the object. Since the coating component has a strong absorption effect on ultraviolet light, if the tablet coating has defective parts such as damage or unevenness, the difference between the ultraviolet absorption of the defective part and the reflection of ultraviolet light by the coating part of the good part will be relatively large. When the ultraviolet image of the tablet is taken by the UV camera, the defective part of the coating will form a large contrast with the good part, so the cracks, damage, unevenness and other problems of the coating can be more easily detected through the UV image. If the coating thickness is insufficient, it will also cause the overall ultraviolet absorption of the tablet to be reduced, resulting in the reflected ultraviolet light intensity being higher than that of the good tablet. Therefore, when a UV image of a tablet is captured by a UV camera, tablets with insufficient coating thickness or tablets with excessive coating thickness will also show a different color depth from that of good tablets.

[0066] At the same time, an image processing unit connected to the ultraviolet camera is also configured. After obtaining the ultraviolet image taken by the ultraviolet camera, the image processing unit extracts the tablet image in the image and analyzes the tablet image. For example, if there is an area with a large contrast with the surrounding area in the tablet image, the tablet is determined to be a defective coated tablet, or if there is a certain number of pixels in the tablet image whose color values ​​(such as grayscale values) are higher or lower than the preset good coating color values ​​(such as grayscale values), the tablet is determined to be a defective coated tablet. After determining the defective coated tablet, the coordinates of the defective coated tablet are further determined.

[0067] The application of ultraviolet cameras and image processing units belongs to the prior art.

[0068] In addition, the working principle of this embodiment is:

[0069] In the present invention, a front-end feeding component is provided to feed the granular tablets to be tested. The fed granular tablets to be tested can be arranged one by one in a horizontal placement after passing through the front-end feeding component. The granular tablets to be tested in the horizontal placement are continuously transported, and then transformed into a longitudinal placement after passing through the guide component. The rear-end feeding component is connected to the outlet of the guide component to receive the granular tablets to be tested in the longitudinal placement. Finally, the granular tablets to be tested in the longitudinal placement are clamped in batches by a clamping component and moved to the clamping component on the placement table 12.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
