Description
Technical Field
[0001] The utility model belongs to the technical field of printed graphics, and in particular relates to an automatic visual detection device for printed graphics. Background Art
[0002] In the fields of 3C, food, medicine, etc., the printed materials supporting the products need to be strictly inspected for defects. Usually, the printed materials need to be inspected for the first time and randomly to avoid serious consequences of use caused by printing errors or omissions. In addition to the important information such as text and punctuation, there are also many patterns (such as chemical molecular formulas, corporate trademarks, background patterns) that need to be strictly inspected. Take the medical instructions as an example. There are a lot of dense texts accompanied by detailed instructions in different languages, and some pattern information is embedded in the printed area of the color background. It is difficult to check one by one by human eyes whether there are printing defects.
[0003] In the existing automatic visual inspection device for printed images, on the one hand, it is impossible to accurately place the printed images, so that the quality of the printed images and patterns cannot be accurately inspected. On the other hand, in the usual automatic visual inspection device for printed images, the distance is fixed relative to the printed images. When facing relatively thick images, it is impossible to detect them. It is also necessary to adjust the distance between the detector and the images in order to detect the images. This method wastes a lot of time for printed image inspection.
[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0026] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.
[0028] See also Figure 1-Figure 6 As shown, the utility model is an automatic visual inspection device for printed images and texts, comprising a workbench 1, a positioning assembly 2 is fixedly installed on the top of the workbench 1, a driving assembly 3 is fixedly installed on the bottom of the positioning assembly 2, a lifting assembly 4 is fixedly installed on the top of the workbench 1, a detector 5 is fixedly installed at one end of the middle part of the lifting assembly 4 close to the positioning assembly 2, and the detector 5 is located directly above the positioning assembly 2.
[0029] During operation, the printed image is first placed on the workbench 1, that is, on the central axis of the positioning component 2 fixedly installed on the workbench 1. Then, if the printed image needs to be positioned, the positioning component 2 is driven to move, that is, the four corners of the positioning component 2 are moved closer to each other, and the edge of the image on the central axis is synchronously positioned to prevent the image from being improperly placed during detection, which may cause inaccurate image detection data of the detector. After the image is positioned, the lifting component 4 needs to be driven to rotate, and then the lifting component 4 will drive the detector 5 fixedly installed in the middle to move toward the direction of the image until the detector 5 detects the entire image. The lifting component 4 drives the detector 5 to move, so that there is a certain moving space between the detector 5 and the printed image, so that the detector 5 can detect relatively thick images.
[0030] Thus, by placing the printed image on the central axis of the positioning component 2 and then driving the four corners of the positioning component 2 to move closer to each other, and synchronously positioning the edge of the image on the central axis, it is prevented that the detector will not detect the image data accurately due to improper placement of the image during detection, which greatly reduces the time for printed image detection and increases the practicality of the detection device for printed image detection.
[0031] In one embodiment, for the above-mentioned workbench 1 , the workbench 1 comprises a shell 101 , two cabinet doors 102 are rotatably mounted on one end of the shell 101 , and support legs 103 are fixedly mounted on the four corners of the bottom of the shell 101 .
[0032] When it is necessary to inspect the inside of the detection device, the operator can open the two cabinet doors 102 by hand, and then observe the situation inside the detection device, which is also convenient for inspecting the inside of the detection device. The support legs 103 support the device.
[0033] In one embodiment, for the above-mentioned positioning component 2, the positioning component 2 includes four positioning claws 201, and the outer shell 101 is provided with a sliding groove 104 that slides with the four positioning claws 201. The bottom of the four positioning claws 201 is rotatably installed with a rotating rod 202, and the ends of the four rotating rods 202 that are close to each other are rotatably installed on a rotating block 203, and the top of the rotating block 203 is rotatably installed on the outer shell 101.
[0034] The driving assembly 3 includes two support rods 301 , and the two support rods 301 are respectively fixedly mounted on two symmetrical positioning claws 201 , and a telescopic rod 302 is fixedly mounted on one end of the two support rods 301 close to each other.
[0035] When it is necessary to position the printed image, first drive the output end of the telescopic rod 302 to drive the support rods 301 at both ends to move. Since the support rods 301 are fixedly mounted on the positioning claws 201, the positioning claws 201 will then drive the rotating rods 202 on each of them to rotate, and the rotating rods 202 will drive the rotating blocks 203 to rotate, and the rotating blocks 203 will drive the four rotating rods 202 to rotate, and then the rotating rods 202 will respectively drive their respective positioning claws 201 to move closer to each other, and then the four positioning claws 201 will move simultaneously to synchronously position the printed image, so as to prevent the problem of inaccurate image detection data caused by the detector due to improper placement during detection, greatly reducing the time for printed image detection and increasing the practicality of the detection device for printed image detection.
[0036] In one embodiment, for the above-mentioned lifting component 4, the lifting component 4 includes a support frame 401, the support frame 401 is fixedly installed on the top of the shell 101, a rotating shaft 402 is rotatably installed inside the support frame 401, and one end of the rotating shaft 402 is rotatably installed on a servo motor 403.
[0037] A first synchronous wheel 404 is fixedly mounted on the other end of the rotating shaft 402 . A synchronous belt 405 is rotatably mounted on the circumferential surface of the first synchronous wheel 404 . A second synchronous wheel 406 is rotatably mounted on the other end of the synchronous belt 405 .
[0038] The second synchronous wheel 406 is rotatably mounted on the support frame 401 , a lifting plate 407 is fixedly mounted on the middle of the synchronous belt 405 , the lifting plate 407 is slidably mounted on the support frame 401 , and the detector 5 is fixedly mounted on the lifting plate 407 .
[0039] When printing relatively thick images and texts, the output end of the servo motor 403 will first be driven to drive the fixed rotating shaft 402 to rotate, and then the rotating shaft 402 will drive the fixed first synchronous wheel 404 to rotate. At the same time, the first synchronous wheel 404 will drive the rotatably installed synchronous belt 405 to rotate, and then the synchronous belt 405 will rotate under the support of the second synchronous wheel 406, and the second synchronous wheel 406 will drive the lifting plate 407 fixedly installed in the middle to move. Since the lifting plate 407 and the detector 5 are fixedly installed, the lifting plate 407 will then drive the fixedly installed detector 5 to move, and then the detector 5 will detect the printed images and texts. Through the movement of the detector 5, there can be a certain moving space between the detector 5 and the printed images and texts, so that the detector 5 can detect relatively thick printed images and texts.
