[0046] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0047] This application provides a handheld conditional scanner, which solves the problem of inconvenient assembly and disassembly of existing integrated scanners, and achieves efficient maintenance.

[0048] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0049] Existing handheld barcode scanners are often designed as a single unit, which makes assembly and disassembly inconvenient, resulting in low efficiency in subsequent barcode scanner maintenance.

[0050] Research has found that, for example Figures 1-9 As shown, by setting the scanner in the form of a front box, handle and rear cover, it is easy to assemble and disassemble the scanner, and thus easy to maintain the scanner.

[0051] Furthermore, a reinforcing block is installed inside the front box, which can increase the depth of the threaded hole, thereby ensuring the aesthetic appearance of the front box and the back cover assembly while enhancing the stability of the installation of the back cover and the front box.

[0052] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0053] Example:

[0054] like Figures 1-2 and Figure 5 As shown, a handheld conditional scanner includes a front end box 1, a handle 2, and a rear cover 21, wherein the handle 2 is mounted to the front end box 1 via the rear cover 21;

[0055] The front-end box 1 is equipped with a scanning head 3, and the front end of the scanning head 3 scans the conditional QR code through the contact interface 4.

[0056] The rear cover 21 is assembled onto the front box 1 via a nesting slot 10;

[0057] The front box 1 is provided with a plurality of reinforcing blocks 101, each of which has a threaded hole, and the plurality of threaded holes are connected to the nesting groove 10. The rear cover 21 has a plurality of mounting holes corresponding to the threaded holes.

[0058] During assembly, the back cover 21 is fitted onto the front box 1 and fixed with bolts passing through the corresponding mounting holes and threaded holes, and the four sides of the back cover 21 are flush with the four sides of the front box 1.

[0059] By setting the scanner in the form of a front box 1, a handle 2 and a rear cover 21, it is easy to assemble and disassemble the scanner, thereby facilitating the maintenance of the scanner.

[0060] Furthermore, a reinforcing block 101 is provided inside the front box 1, which can increase the depth of the threaded hole, thereby ensuring the aesthetic appearance of the front box 1 and the back cover 21 assembly while enhancing the stability of the installation of the back cover 21 and the front box 1.

[0061] like Figure 1 As shown, a rubber sleeve 20 is provided on the handle 2. The rubber sleeve 20 is used to improve the stability between the hand and the handle 2 when the hand is holding the wall scanner, thereby enhancing the stability of the scanning head when scanning conditional QR codes.

[0062] like Figure 3 As shown, at least one speaker 22 is installed on the end of the rear cover 21 near the front box 1. Each speaker 22 is located in the corresponding mounting groove of the rear cover 21 and forms a gap with the rear cover 21.

[0063] The rear cover 21 has multiple through holes 211 distributed at the corresponding positions where the speaker 22 is installed. The multiple through holes 211 are connected to the corresponding gaps for the transmission of sound from the speaker 22.

[0064] By setting a mounting slot on the rear cover 21, the speaker 22 is placed in the corresponding mounting slot, thus realizing the installation of the speaker 22. The sound generated by the speaker 22 is transmitted back in the gap between the speaker 22 and the corresponding mounting slot and is transmitted through the through hole 211, which helps to improve the sound quality of the speaker 22.

[0065] like Figures 4-6 As shown, a limiting groove 40 is provided inside the front end box 1, and the limiting groove 40 is in communication with the abutment interface 4;

[0066] The edge of the abutment 4 is provided with a plurality of spacer grooves 42, and an inclined support plate 41 is formed between two adjacent spacer grooves 42.

[0067] The scanning head 3 is provided with multiple abutment slots 30 that correspond one-to-one with the inclined support plate 41;

[0068] The end of the scanning head 3 near the abutment interface 4 is embedded in the limiting groove 40, and is sealed to the front end of the front end box 1 by the abutment groove 30 and the inclined support plate 41.

[0069] By setting the abutment groove 30, the limiting groove 40, the inclined support plate 41 and the interval groove 42, the front end of the scanning head 3 and the abutment interface 4 of the front end box 1 are sealed, which can effectively improve the sealing degree of the scanning end of the scanning head 3 and the front end box 1 as a whole, which helps the stability of the scanning head 3 inside the front end box 1, and thus effectively prevents the problem of poor contact caused by the loosening of the scanning head 3.

[0070] like Figures 3-4 as well as Figure 7 As shown, the front-end box 1 is also equipped with a communication structure, a power supply structure, and control lines;

[0071] The communication structure is used to upload the data bound to the barcode scanned by the scanner head 3 to the database;

[0072] The power supply structure provides power to the entire scanner.

[0073] Offline scanning operation of the barcode scanner is achieved through communication and power supply structures;

[0074] Specifically, the communication structure includes a board 31 and a circuit board 32;

[0075] The power supply structure includes at least one battery 11;

[0076] The multiple batteries 11 are all electrically connected to the circuit board 32 and provide power to the circuit board 32, the speaker 22, the scanning head 3 and the LCD screen mounted on the rear cover 21;

[0077] The board 31 is electrically connected to the circuit board 32.

[0078] It should be noted that board 31 can be a Raspberry Pi, battery 11 can be a pouch battery, and handle 2 is equipped with multiple operation switches. These switches are used to power on / off, clear memory, and trigger functions. The operation switches control the scanning operation of the barcode scanner, and with software support, conditional scanning is achieved. The scanning head 3 performs offline scanning via communication and power supply structures. The principle of circuit board 32 is as follows... Figure 9 As shown, this is the existing technology of barcode scanners, which will not be elaborated upon here.

[0079] like Figures 3-4 as well as Figure 7 As shown, the board 31 is fixedly connected to the scanning head 3 via a fixing plate 311;

[0080] The board 31 is plugged into the circuit board 32;

[0081] The fixing plate 311 supports the board 31 and the circuit board 32 on the board 31, improving the compactness of the internal layout of the front box 1, and at the same time, improving the stability of the installation of the board 31 and the circuit board 32.

[0082] like Figure 4 As shown, the circuit board 32 is located at the end of the board 31 away from the scanning head 3, and is fixed to the front box 1 by the support rod 321.

[0083] Specifically, the support rod 321 is fixed to the front box 1 by bolts, and the circuit board 32 is attached to the support rod 321 by an arc groove, so that the support rod 321 supports the circuit board 32.

[0084] By setting up a support rod 321 to support the circuit board 32, the overall stability of the circuit board 32 can be improved, thereby improving the stability of signal transmission of the circuit board 32.

[0085] It should be noted that the scanning head 3 is used to scan conditional QR codes, complete the binding of the QR code of the cigarette pack with the QR code of the cigarette carton, and upload the bound data to the database;

[0086] The scanning area 5 on the scanning head 3 is a strip-shaped area, and the area of ​​the strip-shaped area is larger than the area of ​​the scanning target area.

[0087] During assembly, the end of the scanning head 3 with the abutment groove 30 is first embedded in the abutment interface 4, and the abutment groove 30 is aligned with the inclined support plate 41 on the abutment interface 4 to complete the sealed installation of the scanning head 3 and the front end box 1. At the same time, the battery 11 is installed inside the front end box 1 to provide power.

[0088] Next, the board 31 is installed on the scanning head 3 via the fixing plate 311, and the installation of the board 31 is completed by using bolts to pass through the board 31, the fixing plate 311 and the scanning head 3.

[0089] After the board 31 is installed, the support rod 321 is fixed to the side wall of the front box 1, and the circuit board 32 near the end of the board 31 is connected to the board 31 by plugging. At this time, the circuit board 32 is attached to the support rod 321, and the support rod 321 is used for further support.

[0090] Then, the speaker 22 and the LCD screen are installed in the corresponding positions on the back cover 21, and the wiring is laid out. The back cover 21 is then fitted onto the front box 1, and bolts are passed through the corresponding mounting holes and threaded holes to complete the overall assembly.

[0091] In practical applications, in cigarette packaging, every 20 cigarettes are packaged into a basic packaging unit called a "box," which is the unit for retail cigarettes; every 10 small boxes are packaged into a long strip-shaped packaging box, called a "carton," which is the unit for both retail and wholesale cigarettes.

[0092] To strengthen the planning and market management of cigarette production, each cigarette factory prints a unique QR code issued by the State Tobacco Monopoly Administration on the boxes, cartons, and cases of cigarettes during production, and completes a one-to-many binding between the QR code of the case and the QR code of the carton. For example, a 1-to-50 binding is completed between the QR code of the case and the QR code of the carton.

[0093] In existing technologies, the "surface scanning" method requires successfully scanning 50 QR codes in a single pass. This places high demands on the number of scanning heads, resolution, and debugging accuracy. However, for cigarette cartons with highly reflective transparent paper packaging and soldering marks, the failure rate for successfully scanning 50 QR codes in one pass is relatively high. If even one code fails to scan, the position of the cartons must be adjusted, and the scanning must be repeated. The equipment has poor fault tolerance, is bulky, and inconvenient to move. It requires manual handling of the cigarette cartons to be placed in the equipment for scanning and binding, resulting in a large amount of production handling work and low overall work efficiency.

[0094] Therefore, this application provides a handheld, lightweight, portable, continuous, multi-layer scanning "line scan" solution to pursue high overall work efficiency;

[0095] "Line scanning" achieves this by using a scanning head that only parses the QR code within the image area. Therefore, with the same parsing capability, a smaller image area increases the probability of correctly parsing the QR code within that area. In "area scanning" mode, the image area captured is the entire area containing the QR code on a cigarette pack. The parsing capability per unit area is smaller, resulting in a lower probability of successful parsing. Conversely, by setting the image area to a "strip" shape, the image area is significantly reduced, resulting in a high parsing capability per unit area and a significantly higher probability of successful scanning.

[0096] It should be noted that the improvements of this utility model are in the installation of the handle 2 and the front-end box 1 on the barcode scanner, the installation of the scanning head 3 and the front-end box 1, the installation of the circuit board 32 and the front-end box 1, and, in order to improve the probability of successful scanning and analysis, setting the scanning area 5 on the scanning head 3 as a strip-shaped area, and the area of ​​the strip-shaped area is larger than the area of ​​the target area in a single scan, ensuring full coverage of the physical target area in the horizontal direction, as detailed below. Figure 8 As shown;

[0097] This application achieves miniaturization, lightweighting, and handheld operation of the equipment, avoiding handling during the production process. The QR code binding of cigarette cartons and cases can be completed right next to the production line.

[0098] In summary, compared with existing technologies, it has the following beneficial effects:

[0099] 1. By setting the scanner as a unit consisting of a front box 1, a handle 2, and a rear cover 21, the scanner can be easily assembled and disassembled, thus facilitating the maintenance of the scanner.

[0100] Furthermore, a reinforcing block 101 is provided inside the front box 1, which can increase the depth of the threaded hole, thereby ensuring the aesthetic appearance of the front box 1 and the back cover 21 assembly while enhancing the stability of the installation of the back cover 21 and the front box 1.

[0101] 2. By setting the abutment groove 30, the limiting groove 40, the inclined support plate 41 and the interval groove 42, the front end of the scanning head 3 and the abutment interface 4 of the front end box 1 are sealed, which can effectively improve the sealing degree of the scanning end of the scanning head 3 and the front end box 1 as a whole, which helps the stability of the scanning head 3 inside the front end box 1, and thus effectively prevents the problem of poor contact caused by the loosening of the scanning head 3.

[0102] 3. By setting up the support rod 321, the circuit board 32 can be supported by the support rod 321, which can improve the overall stability of the circuit board 32 and thus improve the stability of signal transmission of the circuit board 32.
