Display for reading vaccine packaging steel seal code

Abstract

The invention belongs to the technical field of public health, and particularly relates to a display for reading vaccine packaging steel seal codes, which comprises an electric torch, a lens frame is detachably arranged on the front side of the electric torch, a convex lens is detachably arranged in the lens frame, a blue filter is detachably arranged in the lens frame, the blue filter is arranged on one side of the convex lens, and the convex lens is arranged on the other side of the blue filter. The blue filter is arranged in the lens frame; the blue filter provided by the invention can change the color of light rays emitted by the flashlight, so that the light rays become blue light. When the blue light irradiates the product box, if the background color and the blue light form a large contrast ratio, the steel seal information can be more prominent, and the steel seal information can be rapidly positioned and read in a complex light environment, especially under the condition that the background color is dark or disordered.

Description

Technical Field

[0001] The present invention belongs to the technical field of public health, and specifically refers to a display for reading steel stamp codes on vaccine packaging. Background Art

[0002] The steel stamp on the vaccine packaging box is a concave and convex mark formed on the surface of the material by mechanical pressure, which is often used to identify key data such as product production information, batch number, expiration date, anti-counterfeiting mark, etc. The steel stamp plays an important role in product traceability and anti-counterfeiting verification due to its durability and difficulty in tampering. However, in actual applications, reading the steel stamp information often faces challenges.

[0003] Since the stamp itself has no color, the presentation of its information is completely dependent on the lighting and viewing angle. In low light or at a poor lighting angle, the stamped information may become blurred and difficult to read. In addition, factors such as the material, color, and surface treatment of the product box may also affect the readability of the stamped code. For example, dark or highly reflective materials may obscure the stamped information, making it more difficult to read.

[0004] At present, although there are some devices on the market specifically for reading steel stamp information, these devices are often bulky, complicated to operate, and expensive, and are not suitable for all scenarios. Summary of the invention

[0005] In order to solve the above-mentioned problem, the present invention proposes a display for reading the steel stamp code on vaccine packaging.

[0006] The technical solution adopted by the present invention is as follows: The present invention provides a display for reading the steel stamp code on vaccine packaging, including a flashlight, a lens frame is detachably provided on the front side of the flashlight, a convex lens is detachably provided in the lens frame, a blue filter is detachably provided in the lens frame, and the blue filter is arranged on one side of the convex lens.

[0007] Furthermore, the blue filter is arranged in a lens frame.

[0008] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The blue filter can change the color of the light emitted by the flashlight, turning it into blue light. When this blue light is irradiated on the vaccine box, if the background color forms a large contrast with the blue light, the stamped information will appear more prominent, which helps to quickly locate and read the stamped information in complex lighting environments, especially when the background color is dark or cluttered.

[0009] (2) Metal stamps will produce reflections under certain light conditions, making the information difficult to read. Blue filters can help reduce this reflection interference. By reducing reflections, the flashlight can illuminate the stamped information more clearly, improving the accuracy of reading.

[0010] (3) In scenarios such as production lines, warehouses, and cold storage where product information needs to be quickly identified, the application itself can significantly improve identification efficiency.

[0011] (4) Users do not need to use complicated detection equipment or spend a lot of time looking for the best reading angle. All they need to do is turn on the flashlight and shake it slightly. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to more clearly illustrate the technical solution of the present invention, the accompanying drawings required for use in the description will be briefly introduced below. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For ordinary technicians in this field, other accompanying drawings can be obtained based on these accompanying drawings without paying creative work.

[0014] Among them, 1. flashlight, 2. blue filter, 3. lens frame, 4. convex lens. DETAILED DESCRIPTION

[0015] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0016] like Figure 1-Figure 2 As shown, the present invention proposes a display for reading the steel stamp code on the vaccine packaging, including a flashlight 1, a lens frame 3 is detachably provided on the front side of the flashlight 1, a convex lens 4 is detachably provided in the lens frame 3, a blue filter 2 is detachably provided in the lens frame 3, the blue filter 2 is arranged on one side of the convex lens 4, and the blue filter 2 is arranged in the lens frame 3.

[0017] During specific use, turn on the flashlight 1, illuminate the steel stamp on the vaccine box through the blue filter 2 and shake the flashlight 1 slightly. The background color of the product box forms a large contrast with the blue light. Then, installing the blue filter 2 will make the steel stamp more prominent, making it easier to see the production information, expiration date and batch number. The blue filter 2 helps to reduce reflection interference and improve the visibility of the steel stamp. The above is the overall workflow of the present invention. Just repeat this step next time you use it.

[0018] It can be seen from the above embodiments that the beneficial effects of the present invention are: The blue filter can change the color of the light emitted by the flashlight, turning it into blue light. When this blue light is irradiated on the vaccine box, if the background color forms a large contrast with the blue light, the stamped information will appear more prominent, which helps to quickly locate and read the stamped information in complex lighting environments, especially when the background color is darker or more cluttered; metal stamps will produce reflections under specific light, making the information difficult to read. The blue filter helps to reduce this reflection interference. By reducing the reflection, the flashlight can illuminate the stamped information more clearly and improve the accuracy of reading; in scenes such as production lines, warehouses, cold storage, etc. where product information needs to be quickly identified, the application itself can significantly improve the recognition efficiency; users do not need to use complex detection equipment or spend a lot of time looking for the best reading angle, just turn on the flashlight and shake it slightly.

[0019] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
