Description

Technical Field

[0001] The utility model relates to the technical field of printed invisible pattern identification, in particular to a device for identifying printed invisible patterns. Background Art

[0002] With the diversification of commodity packaging, invisible patterns printed on bottle caps are widely used as an anti-counterfeiting technology. Existing invisible pattern identification technologies for bottle caps mainly include two methods: physical detection and chemical detection. Physical detection methods such as optical detection and electrical detection are simple to operate, have a short detection time, and can quickly obtain detection results, but the detection effect on invisible patterns is poor and is easily affected by environmental factors. Chemical detection methods such as chromatography and mass spectrometry have high accuracy, but the detection time is long and the detection results cannot be obtained quickly. Buyers need to know the authenticity of the goods immediately when purchasing them. Therefore, the chemical detection method is not suitable for use when selling goods. For merchants selling goods, when buyers have identification requirements, since the chemical detection method requires more time to wait for the test results during the test, merchants mainly use physical detection methods for detection, but at the same time, the intensity of ambient light will also affect the detection efficiency and test results. For example, too strong light may cause exposure and affect the detection, and too weak light will increase the difficulty of identifying the pattern on the bottle cap. Utility Model Content

[0003] In view of the shortcomings of the prior art, the utility model provides a device for identifying printed invisible patterns, aiming to solve the problem that environmental factors may affect the detection results when merchants use physical detection methods to detect bottle caps to determine the authenticity of goods.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: a device for identifying printed invisible patterns, including a detection table, an image acquisition device is fixedly installed on the detection table, a light sensor is fixedly installed on the image acquisition device, and a lighting lamp is also fixedly installed on the image acquisition device, and also includes a controller, and the image acquisition device, the light sensor and the lighting lamp are all electrically connected to the controller.

[0005] The principles of this solution are:

[0006] After placing the object to be tested on the testing table under the image acquisition device, the controller controls the light sensor installed on the image acquisition device to detect the light intensity of the environment, and then transmits the detected result to the controller. The controller controls the gear of the lighting lamp according to the detection result feedback from the light sensor, thereby ensuring that the object to be tested on the testing table is in an environment with good lighting, thereby ensuring the image quality of the object captured by the image acquisition device. After the image acquisition device captures the image of the object, it transmits the image to the controller. The controller determines the authenticity of the current object based on the image transmitted back by the image acquisition device.

[0007] The beneficial effects of this program are:

[0008] 1. By installing the light sensor, when using the device, adjust the gear of the lighting lamp according to the ambient light detected by the light sensor, so as to ensure that the objects to be tested placed on the test table are in a good light environment during testing, thereby reducing the impact of the environment on the test results and improving the efficiency and quality of the test.

[0009] 2. After the first adjustment of the lighting position, there is no need to adjust the light again during subsequent testing, saving testing time.

[0010] Furthermore, a placement slot for placing the object to be tested is provided on the upper surface of the detection table directly below the image acquisition device, and a positioning stake is fixedly installed in the placement slot, and the positioning stake is triangular in the placement slot. The placement slot is provided directly below the image acquisition device, so that the object to be tested can be quickly placed directly below the image acquisition device, and the positioning stake in the placement slot can be set so that when the object to be tested is placed in the placement slot, the positioning stake can position the object to be tested, so that the objects to be tested placed below the image acquisition device are in the same direction, and the controller can quickly obtain the detection result according to the image feedback from the image acquisition device.

[0011] Furthermore, the positioning stake is located at the center of the placement slot. Ensure that the object to be tested is placed at the center of the placement slot. In the image captured by the image acquisition device, the object to be tested is located at the exact center of the image. The lighting lamp is installed on the image acquisition device, so the position with the highest light on the test table is directly below the image acquisition device, that is, at the center of the placement slot. Positioning the object to be tested at the center of the placement slot makes the image captured by the image acquisition device have the highest imaging quality, so as to facilitate fast and accurate image processing.

[0012] Furthermore, an alarm is fixedly mounted on the controller. When the image captured by the image acquisition device indicates that the object to be detected is a counterfeit, the controller controls the alarm to sound an alarm to prompt the staff or the owner of the object to be detected.

[0013] Furthermore, a display screen is fixedly mounted on the controller. When the staff or the owner of the object to be detected performs the detection of the object to be detected, the detection result can be read from the display screen, so that the deaf-mute can also perform the detection by themselves.

[0014] Furthermore, at least one sizing groove extending outward is provided on the outer circumference of the placement groove along the circumference of the placement groove, and a sizing plate is fixedly installed in each sizing groove. The sizing plate is arranged so that the same detection device can detect objects of different diameters, and the objects of different diameters can be fixed and placed by installing different sizing plates.

DETAILED DESCRIPTION

[0019] The following is further described in detail through specific implementation methods:

[0020] like Figure 1-3As shown, the structure of a device for identifying printed invisible patterns is as follows: it includes a detection table 101 that can be placed on the ground or on a table, the lower end of the vertical rod in the "┐"-shaped support rod is fixedly installed on the detection table 101 vertically by welding or bolting, and the open end of the horizontal rod is welded to an image acquisition device 102, and the image acquisition device 102 is used to acquire images of the object to be tested placed on the detection table 101. It can be imagined that the acquisition component of the image acquisition device 102 is located above the detection table 101, and the installation between the detection table 101 and the acquisition component of the image acquisition device 102 can be achieved through the support rod. An illuminating lamp 103 is fixedly installed on the image acquisition device 102 by inlaying or bolting, and a light sensor 104 is fixedly installed on the image acquisition device 102 by bolting or welding; it also includes a controller 105, and the controller 105 in this application is a controller 105 with embedded software , and the related functions implemented by the software in the controller 105 are all ways of implementing the functions in the prior art. The controller 105 can be fixedly mounted on the detection platform 101, or installed at other positions outside the detection platform 101. The input end of the image acquisition device 102 is connected to the output end of the controller 105, and the output end of the image acquisition device 102 is connected to the input end of the controller 105, so as to control the working state of the image acquisition device 102 and the data feedback of the image acquisition device 102 through the controller 105. The output end of the controller 105 is connected to the input end of the illuminating lamp 103, so as to control the working state of the illuminating lamp 103 through the controller 105. The output end of the controller 105 is connected to the input end of the light sensor 104, and the input end of the controller 105 is connected to the output end of the light sensor 104, so as to control the working state of the light sensor 104 and the data feedback of the light sensor 104 through the controller 105.

[0021] A placement slot 201 for placing the object to be tested is provided on the inspection table 101 directly below the image acquisition device 102, and a positioning pile 202 is fixedly installed in the placement slot 201 by means of one-piece molding or welding fixation. The positioning pile 202 is triangular in the placement slot 201. It is easy to imagine that the purpose of providing the positioning pile 202 in the placement slot 201 is to achieve the positioning of the object to be tested. It is necessary to have a groove corresponding to the positioning pile 202 on the object to be tested to achieve the positioning of the object to be tested. Therefore, when the object to be tested is produced, a corresponding groove is provided on the object to be tested; and the positioning pile 202 in the placement slot 201 is located at the center of the placement slot 201. When the positioning pile 202 achieves the positioning of the object to be tested, the object to be tested is positioned at the center of the placement slot 201, so that when the image acquisition device 102 captures an image of the object to be tested, the object to be tested is located at the center of the captured image.

[0022] An alarm 106 is fixedly mounted on the controller 105 by bolting or welding, and a display screen 107 is fixedly mounted by embedding or bolting. The input end of the alarm 106 is connected to the output end of the controller 105 so that the working state of the alarm 106 can be controlled by the controller 105. The input end of the display screen 107 is connected to the output end of the controller 105 so that the display screen 107 can display the image of the object to be tested and the detection result through the controller 105.

[0023] A sizing groove 203 extending outward from the placement groove 201 is opened on the outer periphery of the placement groove 201 along the circumference of the placement groove 201. A plurality of sizing grooves 203 are opened. A sizing plate 204 is fixedly installed in the sizing groove 203 by means of snap-fitting and the like. The installation of the sizing plate 204 forms placement grooves 201 of different sizes to realize the detection of objects to be tested of different sizes.

[0024] The light sensor 104 in the present application may be a visible light sensor, a sunlight sensor, or the like.

[0025] The specific implementation process is as follows:

[0026] For a more intuitive purpose, the present application takes the bottle cap as an example to illustrate the distance of the implementation process.

[0027] When the seller or buyer needs to determine whether the product packaged in the bottle cap is authentic, the corresponding bottle cap is placed in the placement slot 201 on the detection table 101, and the groove opened on the bottle cap is aligned with the positioning pile 202 in the placement slot 201. Then, the controller 105 controls the light sensor 104 to detect the light intensity of the environment. The light sensor 104 feeds back the detected data to the controller 105. The controller 105 controls the state of the lighting lamp 103 according to the data detected by the light sensor 104, so that the bottle cap on the detection table 101 is in a better lighting environment. Then, the controller 105 controls the image acquisition device 102 to acquire the image of the bottle cap. The image acquisition device 102 transmits the acquired image to the controller 105. The controller 105 controls the working state of the alarm 106 according to the image of the bottle cap. At the same time, the controller 105 transmits the image of the bottle cap acquired by the image acquisition device 102 to the display screen 107 for display, thereby realizing the detection of the bottle cap. In the present application, the authenticity of the bottle cap is determined based on the image presented by the reflection of light from the texture on the bottle cap captured by the image acquisition device 102, and the quality of the detection environment is guaranteed by setting the light sensor 104 to detect the ambient light intensity, thereby ensuring the quality of the detection result and the detection efficiency.

[0028] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
