Description

Technical Field

[0001] The present application relates to production equipment technology, in particular to a disposable needle patch production equipment and a control method thereof. Background Art

[0002] Generally, nurses need to fix the position of the needle during infusion to avoid damage to the patient. The traditional way is to stick the needle to the skin with adhesive tape, but this method is not easy to stick firmly, and the nurse needs to tear the tape into pieces, which is relatively inconvenient.

[0003] Therefore, someone invented the needle patch, which consists of a protective film, a cushion layer and an anti-sticking layer. When using it, the anti-sticking layer is torn off. The side of the cushion layer that fits the anti-sticking layer is provided with adhesive. The nurse directly sticks the needle patch on the patient's injection site. The cavity formed by the hollow position of the protective film and the cushion layer accommodates and fixes the needle tube. It is relatively convenient and not easy to fall off.

[0004] Due to the low penetration rate of needle patches and relatively backward production equipment, products are generally sorted manually. Summary of the invention

[0047] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described through the implementation method with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0048] In the description of the present invention, "several" means more than one, "many" means more than two, "greater than", "less than", "exceed", etc. are understood to exclude the number itself, and "above", "below", "within", etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0049] In the description of the present invention, unless otherwise clearly defined, words such as "setting" should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meaning of the above words in the present invention in combination with the specific content of the technical solution.

[0050] In the description of the present invention, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0051] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , a disposable needle patch production device, the needle patch comprises a protective film 101, a cushion layer 102 and an anti-sticking layer 103 stacked in sequence, and a nanoneedle cavity is arranged in the middle of the cushion layer. Figure 2 As shown, when the needle patch is attached to the user's hand, the needle tube 105 is fixed by the nano-needle cavity 104 of the needle patch.

[0052] The production equipment includes:

[0053] Production components are used to produce products including the needle patch and outer packaging. In this embodiment, the production components used are prior art, and the purpose is to produce the needle patch and its outer packaging.

[0054] The detection component is provided with a camera and a processor, and the processor detects whether the product is qualified according to the product image taken by the camera. Figure 4 It can be seen that if a needle patch itself has defects, such as the hollow part deviating from the center of the product, the center b of the hollow part will not coincide with the center c of the cushion layer. When the distance between point b and point c exceeds a certain value, it means that the product is unqualified. Similarly, since the outer packaging will be heated and cut when it is sealed, if the needle patch itself is too close to the edge of the packaging, it means that part of the needle patch may be partially damaged during the heating and cutting process, which is also an unqualified product. These features can be measured by image detection. The use of image measurement and sorting components can quickly separate unqualified products.

[0055] The sorting component is used to separate the products determined as unqualified by the detection component from the products determined as qualified by the detection component. In this embodiment, the sorting component can be implemented by a mechanical arm with a suction cup. When a defective product is determined, the defective product is sucked away from the production line and separated.

[0056] The embodiment of the present application sets up a production component for producing needle patch and its outer packaging, and sets up a detection component to perform image detection on the needle patch product, and separates the products judged as unqualified by the detection component through a sorting component, which greatly improves the production efficiency. Furthermore, in some embodiments, the geometric characteristics of the needle patch product are utilized, and the image recognition technology is used to identify and separate the unqualified needle patch products, which has a high accuracy rate and is relatively efficient compared to manual sorting.

[0057] In some embodiments, the cushion layer is a hollow cylinder, the hollow part is a cylinder, and the package is a rectangular package. It is understandable that the cushion layer can be a hollow regular cylinder, and the hollow part is also a regular cylinder, and the cushion layer and its hollow geometric center are the same.

[0058] In some embodiments, the cushion layer is a hollow cylinder, the hollow part is a cylinder, the protective film is a circular film, and the package is a square package. The needle patch used in this embodiment is cylindrical, and cylindrical products are relatively convenient to use, and are relatively easy to produce, and have low production costs.

[0059] In some embodiments, the processor detects whether the product is qualified according to the product image captured by the camera, including:

[0060] Get the image captured by the camera;

[0061] Detect whether a first distance bc between a center b of the hollow part of the cushion layer in the image and a center c of the cushion layer is less than a first threshold value; when the first distance is less than or equal to the first threshold value, determine that the product is qualified; when the first distance is greater than the first threshold value, determine that the product is unqualified.

[0062] like Figure 4 As shown, in this embodiment, if the distance between point b and point c is relatively large, it means that the hollow portion deviates from the center of the needle patch, which will cause some edges of the needle patch to not adhere firmly, and the product is unqualified.

[0063] In some embodiments, the processor detects whether the product is qualified according to the product image captured by the camera, including:

[0064] Get the image captured by the camera;

[0065] The minimum distance between the cushion layer and the edge of the outer packaging in the image is detected, and when the minimum distance is greater than or equal to a second threshold, the product is determined to be qualified; when the minimum distance is less than the second threshold, the product is determined to be unqualified.

[0066] like Figure 4As shown, in this embodiment, if the length of line segment a (the minimum distance from the needle patch to the edge of the outer package) is relatively small, it means that the needle patch is relatively close to the edge of the package. There will be a heated and bonded part on the edge of the package. If the needle patch touches or approaches this part, it may cause damage to the needle patch. Therefore, this is also an unqualified product.

[0067] In some embodiments, the processor detects whether the product is qualified according to the product image captured by the camera, including:

[0068] Get the image captured by the camera;

[0069] Detecting whether a first distance between a center of a hollow portion of the cushion layer in the image and a center of the cushion layer is less than a first threshold;

[0070] Detecting the minimum distance between the cushion layer and the edge of the outer packaging in the image;

[0071] When the minimum distance is greater than or equal to the second threshold and the first distance is less than or equal to the first threshold, the product is determined to be qualified; when the minimum distance is less than the second threshold or the first distance is greater than the first threshold, the product is determined to be unqualified.

[0072] In this embodiment, if Figure 4 As shown, the product is determined to be qualified only when the geometric relationship between the needle patch itself and the needle patch and the package meets the requirements, otherwise, the product is determined to be unqualified. This embodiment can screen out different types of unqualified products, thereby ensuring the quality of the product.

[0073] In some embodiments, the processor detects whether the product is qualified according to the product image captured by the camera, specifically including:

[0074] Segmenting the image to obtain sub-images corresponding to multiple products;

[0075] Check whether each product is qualified according to each sub-graph.

[0076] In this embodiment, batches of products can be inspected on the production line at the same time. During the inspection process, the product images are segmented, wherein the image segmentation method and the image segmentation range can be set by the user. That is, the user can set the number of segments and the size of the segmentation frame. Therefore, even if the user adjusts the parameters of the production line, the segmentation method can be quickly and flexibly configured. In addition, the segmentation method is configured by the user, which is more flexible. Compared with the automatic segmentation of the image recognition method, its operation efficiency is higher, and the operation load of the processor is reduced.

[0084] Detecting whether a first distance between a center of a hollow portion of the cushion layer in the image and a center of the cushion layer is less than a first threshold;

[0085] Detecting the minimum distance between the cushion layer and the edge of the outer packaging in the image;

[0086] When the minimum distance is greater than or equal to the second threshold and the first distance is less than or equal to the first threshold, the product is determined to be qualified; when the minimum distance is less than the second threshold or the first distance is greater than the first threshold, the product is determined to be unqualified.
