Abstract
Description
A portable barcode reader light shield Technical Fields
[0001] This utility model relates to the field of cigarette logistics, specifically to a movable barcode reader light shield. Background Technology:
[0002] In my country, cigarettes are subject to strict regulations, and their logistics, transportation, and distribution require rigorous management and record-keeping. When local tobacco bureaus deliver cartons of cigarettes to merchants, they use barcode readers on the conveyor belt to photograph and read the QR codes on the side of the cartons, recording the shipment information. Because the QR codes on different brands of cigarette cartons may be located on the side or at the end, or due to variations in the placement of the cartons during transport, multiple barcode readers need to be installed on both sides of the conveyor belt to prevent unclear images and missed readings.
[0003] During operation, the area around the QR code reader is an open space, which is exposed to sunlight, lamps, and other light sources. The outer surface of the cigarette packs is wrapped in cellophane, which can cause glare and make the QR code unclear, preventing the reader from taking a picture and reading it. If the QR code reading fails, it needs to be read manually. During the manual reading, the entire sorting line needs to be temporarily shut down. After the reading is completed, the sorting line continues to run. The downtime for reading the QR code is 180-240 minutes, which affects sorting efficiency. Invention content and utility model content:
[0004] The purpose of this invention is to provide a portable barcode reader light shield.

[0021] Example
[0022] As shown in Figures 1, 2, and 3, a movable barcode reader light shield includes a platform 2 symmetrically fixed on both sides of a conveyor belt 1. Multiple barcode readers 3 are fixed on the top of the platform 2. In this embodiment, each platform 2 has at least three barcode readers 3. The cameras all point towards the side of the conveyor belt 1. A rectangular cover 4 larger than the platform 2 is provided above the platform 2. The bottom of the rectangular cover 4 covers the platform 2. The rectangular cover 4 can shield the barcode readers 3 and the side of the conveyor belt 1, so that the QR code on the barcode is not affected by the light source, which is conducive to the barcode reader 3 clearly capturing the QR code. Connecting plates 5 are fixed to the bottom of both sides of the platform 2. Connecting rods 6 are fixed to both sides of the rectangular cover 4. The connecting rods 6 are rotatably connected to the connecting plates 5. The rectangular cover 4 can be moved below the platform 2 by rotating the connecting rods 6 downwards, making space for the maintenance of the barcode readers 3.
[0023] Two rectangular covers 4 are each integrally fixed with an n-shaped extension cover 7 on one side of their adjacent sides. The ends of the two extension covers 7 are movably aligned above the conveyor belt 1. The extension covers 7 of the two rectangular covers 4 can also cover the conveyor belt 1, further increasing the covering area and reducing the influence of multi-angle light sources. The extension covers 7 can also move with the rectangular covers 4. The bottom of the two extension covers 7 is higher than the conveyor belt 1, so as not to interfere with the conveying of the carton cigarettes.
[0024] The platform 2 has support plates 8 fixed on both sides to support the bottom of the rectangular cover 4. The bottom size of the rectangular cover 4 is larger than that of the platform 2 so that it can be moved downwards. When placed on top of the platform 2, it can rest on the support plates 8.
[0025] The top of the rectangular cover 4 is provided with an inspection window 9, and the inspection window 9 is covered with a cover 10 that is hinged to the rectangular cover 4. By lifting the cover 10, the barcode reader 3 can be observed or easily inspected in an emergency through the inspection window 9.
[0026] A pair of magnets 11 are fixed to the rectangular cover 4 around the cover 10 and the inspection window 9, the ends of the two extension covers 7, the bottom of the rectangular cover 4 and the top of the support plate 8, respectively. The magnetic poles of the pair of magnets 11 are opposite. The cover 10 can be temporarily locked by magnetic attraction of the pair of magnets 11 when it is fastened to the inspection window 9. When the two extension covers 7 are aligned above the conveyor belt 1, they can also be temporarily locked by magnetic attraction of the magnets 11. The connection between the rectangular cover 4 and the support plate 8 is also temporarily locked by magnetic attraction of the magnets 11. All of these measures can prevent the connection from becoming loose and causing easy shaking.
[0027] The connecting rod 6 is rotatably connected to the connecting plate 5 via a bearing. The bottom of the connecting plate 5 is bolted with a bearing seat 12 for disassembling the bearing. By disassembling the bearing seat 12, the bearing of the connecting rod 6 can be separated from the connecting plate 5, and then the rectangular cover 4 can be disassembled, further freeing up space near the conveyor belt 1, which is convenient for the maintenance of the conveyor belt 1.
[0028] Working principle: When this utility model is in use, each platform 2 has three barcode readers 3, and the cameras are all pointing towards the side of the conveyor belt 1. The bottom of the rectangular cover 4 covers the platform 2 and rests on the support plate 8. The rectangular cover 4 can block the barcode readers 3 and the side of the conveyor belt 1. The two extension covers 7 can block the top of the conveyor belt 1, so that the QR code of the bar box is not affected by the light source, which is conducive to the barcode readers 3 taking clear pictures of the QR code.
[0029] By opening the cover 10, the barcode reader 3 can be observed or easily inspected through the inspection window 9. The rectangular cover 4 can be rotated downwards under the platform 2 via the connecting rod 6, making space easier to inspect the barcode reader 3. By disassembling the bearing seat 12, the connecting rod 6 can be separated from the connecting plate 5, and then the rectangular cover 4 can be disassembled, further freeing up space near the conveyor belt 1, which is convenient for inspecting the conveyor belt 1.
[0030] Advantages: 1. By using the rectangular cover 4 and the extension cover 7 to block the sides of the barcode reader 3 and the conveyor belt 1, the QR code on the barcode is not affected by the light source, reducing reflection, which helps the barcode reader 3 to clearly capture the QR code, reducing the number of reading failures, avoiding manual rereading, and improving sorting efficiency.
[0031] 2. The rectangular cover 4 can be moved to make way for the maintenance of the barcode reader 3, and can also be disassembled for the maintenance of the conveyor belt 1.
[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
