[0002] As an automatic recognition technology, barcode scanning technology can quickly read the rich information contained in barcodes (including one-dimensional and two-dimensional codes) through optical principles. With the widespread application of barcode scanning technology, the demand for matching portable devices is also growing, such as PDAs equipped with barcode scanning technology.

[0003] PDA is the abbreviation of "Personal Digital Assistant". Due to the needs of 5G technology, the current PDA needs to reserve sufficient functional areas on the motherboard, especially the antenna area. The motherboard also needs to be equipped with power buttons, scanner docks, cameras and other structural parts. Among them, the power button is connected to the motherboard through FPC and spring structure, which takes up more space and easily occupies the reserved antenna area, affecting the antenna layout and clearance.

[0004] Furthermore, most PDAs are equipped with a code scanning stand or a code scanning handle. The buttons on the code scanning stand or the code scanning handle need to be connected to the PDA's main board through a complex adapter structure to enable the code scanning action with the stand or the handle. The complex design structure further causes space congestion and affects the layout and clearance of the antenna.

[0005] Therefore, it is urgent to provide a new solution that meets the connection requirements of the code scanning bracket or the code scanning handle while optimizing the layout and clearance of the top antenna. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0036] The embodiment of the present application discloses a dock sweeping device.

[0037] See also Figure 1 , an embodiment of a dock scanning method provided in the embodiments of the present application includes:

[0038] It includes a code scanning base 1, on which a first PCB board 2 is installed, and an interface for connecting to the mainboard is provided on the first PCB board. The code scanning base 1 is a plastic base, on which a code scanning component (camera, fill light, etc.) is installed. The code scanning base 1 is used as a bearing structure to install and fix the code scanning component and the first PCB board 2, and the first PCB board 2 carries the core control and signal processing functions. The specific connection relationship between the code scanning base 1, the first PCB board 2 and the code scanning component, as well as the communication connection relationship between the first PCB board 2 and the mainboard are all existing designs, so they are not described in detail.

[0039] The improved design of the present application is that it also includes a second PCB board 3.

[0040] Since the top and bottom surfaces of the barcode scanning base 1 are used to install the barcode scanning component and the first PCB board 2 respectively, the second PCB board 3 is installed on the outer side of the barcode scanning base 1, and a pad structure 31 is provided thereon. The number of the second PCB board 3 of the present application is one, and it can be installed on any side of the barcode scanning base 1 as needed.

[0041] The second PCB board 3 provided with the pad structure 31 is also called a PAD board, which is a small printed circuit board (PCB), mainly used for specific electronic function modules or as a supplementary part of a large circuit board (whose core part is the PAD (pad)). The second PCB board 3 is used to carry the pad structure 31, and the pad structure 31 can be regarded as an energy-conducting PAD, a metal structure used for energy conduction.

[0042] In the present application, the pad structure 31 may be provided with at least two (eg Figure 1 As shown, the present application is designed with two pad structures 31), and multiple pad structures 31 are designed to connect to the code scanning bracket or the code scanning handle to achieve input expansion.

[0043] The second PCB board 3 is communicatively connected to the first PCB board 2 via the electrical connection structure 4 .

[0044] The sweeping dock designed in this application has the following beneficial effects:

[0045] 1. The pad structure 31 on the second PCB board 3 can be connected to the main board through the first PCB board 2, and the key input signal is connected to the pad structure 31 through the FPC and the spring structure, so as to realize different key functions such as the power button, the code scanning button, and the PPT button, without occupying the antenna area reserved on the main board, thereby optimizing the layout and clearance of the top antenna.

[0046] 2. A pad structure 31 for connecting other inputs is directly added to the code scanning base 1. The buttons on the code scanning bracket or the code scanning handle can also be connected to the pad structure 31 to meet the connection requirements. Compared with the design of leading out from the main board, less materials are required, and thus less space is occupied, which helps to optimize the layout and clearance of the top antenna.

[0047] The above is an embodiment of a scanning dock provided in the embodiment of the present application. The following is an embodiment of a scanning dock provided in the embodiment of the present application. For details, please refer to Figures 1 to 4 .

[0048] Based on the solution of the above embodiment 1:

[0049] Furthermore, if Figure 1 As shown, for the sake of connection reliability and convenience of production and assembly, the electrical connection structure 4 is an FPC connection structure, and the first PCB board 2 and the second PCB board 3 are made into a soft-hard combination board.

[0050] Furthermore, the PCB board is usually installed on a specific position of the base in the form of attachment (such as solder bonding, screw fastening, etc.). Regardless of the installation form, if it is directly installed, there are problems of poor installation accuracy and low installation efficiency. To solve this problem, the present application provides a first positioning structure (not shown in the figure) on the code scanning base 1, and a second positioning structure (not shown in the figure) is provided on the second PCB board 3 to cooperate with the first positioning structure.

[0051] The design of the positioning structure greatly improves production efficiency and assembly accuracy. In a large-scale production environment, the operator (automatic manipulator) can quickly and accurately install the second PCB board 3 to a specific position of the code scanning base 1 based on the precise matching relationship between the first positioning structure and the second positioning structure, without the need for complex adjustment and calibration processes, effectively reducing the time and labor costs required for assembly.

[0052] When the scanning dock is affected by external factors such as vibration, impact or temperature change during daily use, the first positioning structure and the second positioning structure are closely combined, and also act as a solid anchor point to firmly reinforce the position of the second PCB board 3, further preventing it from displacement, loosening or friction and collision with other components, thereby ensuring the normal use of the second PCB board 3.

[0053] The design of the positioning structure can not only accurately position the second PCB board 3 to a specific installation position, but also enhance the installation stability of the second PCB board 3 .

[0054] Further, the first positioning structure is a protruding structure, and the second positioning structure is a slot structure for the protruding structure to be inserted into; or, the first positioning structure is a slot structure, and the second positioning structure is a protruding structure inserted into the slot structure.

[0055] The matching mode of the protrusion and the slot is like a mortise and tenon structure, providing an extremely stable connection effect. When the protrusion structure is accurately inserted into the slot structure, a tight mechanical interlock is formed between the two, effectively limiting the six degrees of freedom of the second PCB board 3 on the code scanning base 1, so that it can remain in place when subjected to external forces in various directions.

[0056] In the manufacturing process, this protrusion-slot positioning structure can greatly simplify the assembly process and improve production efficiency and assembly accuracy.

[0057] Furthermore, at least two protrusion structures are provided and are distributed at intervals; at least two slot structures are provided and correspond one to one with the protrusion structures.

[0058] The multiple protrusion structures distributed at intervals and the corresponding slot structures work together to form a stable multi-point support. Compared with a single positioning point, this multi-point layout can more evenly disperse the external force borne by the second PCB board 3, effectively preventing the deformation, warping or displacement of the PCB board caused by excessive local force.

[0059] Take the case where the first positioning structure is a protruding structure and the second positioning structure is a slot structure for the protruding structure to be inserted into as an example:

[0060] The slot structure can be arranged on the side of the second PCB board 3. By designing the slot structure as the side, the protruding structure can be better exposed to the field of vision during installation, so as to better perform alignment.

[0061] Of course, the slot structure can also be arranged at the bottom of the second PCB board 3 ; wherein the slot structure is a groove or a through slot running through the top of the second PCB board 3 .

[0062] The non-through design can avoid occupying the top space of the second PCB board 3, but the alignment is relatively inconvenient. The through design will occupy the top space of the second PCB board 3, but the alignment is relatively convenient.

[0063] In the present application, the slot structure is preferably arranged on the side of the second PCB board 3 .

[0064] Furthermore, if Figure 2 As shown, in order to better support the second PCB board 3, the position on the outer surface of the code scanning base 1 for installing the second PCB board 3 is at least partially a planar structure 11, so that some positions can support the installation of the second PCB board 3.

[0065] Furthermore, if Figure 2 As shown, the position on the outer side of the code scanning base 1 for mounting the second PCB board 3 is directly set as a plane structure 11.

[0066] like Figure 4 As shown, in the past, a recess 13 was designed at the position on the barcode scanning base 1 for installing the second PCB board 3, and the purpose of designing the recess 13 was to overcome the problem of poor production. When the area is used now, the recess 13 in the area needs to be filled to form the required planar structure 11.

[0067] However, when other components are arranged on the inner side of the scanning base 1 at the position corresponding to the second PCB board 3, the inner side of the scanning base 1 needs to be provided with the following components at the position corresponding to the second PCB board 3: Figure 3 The groove structure 12 (reduced glue treatment) shown is intended to make the side thickness of the scanning base 1 relatively consistent, so as to prevent the scanning base 1 from being deformed locally during injection molding.

[0068] The present application also discloses a terminal device, including a terminal body and a scanning terminal, wherein the scanning terminal is installed on the terminal body.

[0069] The terminal body can be a PDA terminal body, or other terminal device body that needs to use a scanning terminal, and there is no specific limitation.

[0070] The above is a detailed introduction to a terminal scanner and terminal device provided by the present application. For a person skilled in the art, according to the idea of ​​the embodiments of the present application, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
