Description

Technical Field

[0001] The utility model belongs to the technical field of laboratory instruments, and in particular relates to a portable ultraviolet light box used for anti-counterfeiting ink experiments. Background Art

[0002] Fluorescent ink is one of the most widely used chemical anti-counterfeiting inks in modern anti-counterfeiting packaging and printing. It is suitable for the printing of anti-counterfeiting packaging for official documents, securities, certificates, and brand-name products such as high-end tobacco, alcohol, food, medicine, and cosmetics. In the field of anti-counterfeiting technology, ultraviolet light can illuminate the surface of an object, causing specific markings or materials on the object to exhibit a unique fluorescent effect under the illumination of the ultraviolet light, thereby enabling rapid identification and recognition of the object. Because of this characteristic of UV light, UV lamps are often used in laboratories to emit ultraviolet light to stimulate the fluorescence of inks and analyze their properties.

[0003] Although patent CN201820907840.X provides a three-purpose UV analyzer light box composed of a UV lamp placed in a dark box, there is no camera in the UV lamp box that provides ultraviolet light, and it is impossible to flexibly adjust the shooting angle in real time to record the experimental process, which will cause incomplete analysis of the experimental results. When this light box is used to observe the fluorescence reaction of the sample in the laboratory, it may not provide sufficient illumination intensity due to the dispersion of the light source, resulting in an unclear fluorescence effect. For example, when analyzing certain chemical substances, high illumination intensity is required to stimulate obvious fluorescence, and this light box may not meet this requirement. In addition, this light box does not provide a standardized sample placement area. When non-fluorescent paper is used to detect the anti-counterfeiting properties of fluorescent ink, the individual differences of the experimenters lead to inconsistent paper arrangement during the experiment, making the experimental phenomenon appear messy, causing a lot of inconvenience to the experimenters in analyzing the experimental results.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Figure 1-3 As shown, a portable UV light box for anti-counterfeiting ink experiments includes a light box housing 1, two sample table drawers 6, two UV lamps 8, a camera 11 and a controller;

[0029] A handle 5 is provided in the middle of the top surface of the light box shell 1, which makes the ultraviolet light box easier to move. An observation window 4 is provided on the upper part of the side wall. Glass is installed in the observation window. The status of the sample in the ultraviolet light box can be checked through the observation window without taking out the sample. A sliding shielding door is provided in the observation window 4, which can effectively block ultraviolet light and is easy to open and close quickly. The shielding door can ensure that when the observation window is not in use, the ultraviolet light will not affect the surrounding environment or personnel. A black coating is evenly coated on the inner wall of the light box shell 1, and two drawer jacks are provided side by side at the lower part of the front side wall. The two sample table drawers 6 are inserted into the two drawer jacks, and the taking out and putting in between the two drawers do not interfere with each other. The two ultraviolet lamps 8 are respectively Two ultraviolet lamp support rods 7 are arranged on the front side of the top of the light box housing 1 just above the two sample table drawers 6. The wavelengths of the two ultraviolet lamps 8 are 254nm and 365nm respectively. The two ultraviolet lamps 8 are provided with reflectors 9, which are used to converge the ultraviolet light to enhance the ultraviolet lighting effect of the sample. At the same time, it will adjust the light during the camera shooting process to facilitate obtaining better shooting effects. A guide rail 10 is horizontally provided between the two side walls of the light box housing 1. The camera 11 is slidably set on the guide rail 10, and the camera 11 is located behind the ultraviolet lamp 8 to prevent the reflector 9 from blocking the shooting range of the camera 11. A camera switch 2 and an ultraviolet lamp switch 3 are provided on the upper part of the outer wall of the light box housing 1;

[0030] The controller is arranged on the outer wall of the light box shell 1, and is electrically connected to the camera 11 and the camera sliding device. The ultraviolet lamp 8 is electrically connected to the ultraviolet lamp switch 3, and the camera 11 is electrically connected to the camera switch 2. The ultraviolet lamp 8 and the camera 11 are externally connected to the power supply.

[0031] The top surface of the sample table drawer 6 is coated with matte paint to avoid interference with the test results. A number of non-fluorescent paper slots 6.1 are evenly arranged in the middle to place non-fluorescent paper samples of fixed size. The sizes are the same, which avoids the uneven paper arrangement due to individual differences in the experiment. At the same time, the pull-out design also makes it convenient for the experimenter to place the sample. A handle 6.2 is provided on the front wall, and the front side of the interior is a first storage box 6.3. A number of non-fluorescent paper storage boxes 6.4 are evenly and vertically arranged on the upper part of the rear side, and a second storage box 6.5 is provided on the lower part of the rear side. The second storage box 6.5 is provided with a clamp of adjustable size, which is mainly used to place and fix beakers or cuvettes to avoid spilling samples in the cuvettes or beakers, thereby affecting the shooting effect and polluting the internal environment of the box.

[0032] The top surface of the sample stage drawer 6 may also be coated with black latex paint.

[0033] The use process of this utility model:

[0034] When the present invention is used, the non-fluorescent paper samples to be tested dipped in fluorescent ink are divided into two groups, the sample stage drawer 6 is pulled out by the handle 6.2, one group of non-fluorescent paper samples is inserted into the non-fluorescent paper card slot 6.1 on the top surface of one sample stage drawer 6, and then the sample stage drawer 6 is pushed in, and the camera 11 and the ultraviolet lamp 8 with a wavelength of 254nm are turned on by the camera switch 2 and the ultraviolet lamp switch 3. During the process of the ultraviolet lamp 8 irradiating the non-fluorescent paper samples to be tested, the experimenter adjusts the camera 11 to move left and right along the guide rail 10 in real time through the controller, thereby comprehensively recording the changes of the samples during the experiment. At the same time, the experimenter can also observe the changes of the samples in real time through the observation window 4. A group of samples contains several samples, which can prevent the occurrence of accidental phenomena during the experiment, and the average value of the experiment is obtained through multiple samples.

[0035] After one set of sample tests is completed, pull out the two sample table drawers 6 and take out the tested non-fluorescent paper samples. Then insert another set of non-fluorescent paper samples to be tested into the non-fluorescent paper card slot 6.1 on the other sample table drawer 6. Turn off the 254nm ultraviolet lamp 8 through the ultraviolet lamp switch 3 and turn on the 365nm ultraviolet lamp 8. Repeat the above steps to test the changes in the results of the non-fluorescent paper samples under the irradiation of the ultraviolet lamp 8 of different wavelengths, and record the experimental changes.

[0036] Unused non-fluorescent paper samples are stored in the non-fluorescent paper storage box 6.4, and fixed beakers or cuvettes are stored in the second storage box 6.5 through a size-adjustable clamp. The first storage box 6.3 is used to store other related instruments, utensils, etc.
