AI Technical Summary
Existing barcode reading modules have weak heat dissipation capabilities in small sizes and complex structures, making it difficult to achieve excellent barcode reading capabilities.
The main control board, conversion board, and acquisition board are connected by flexible flat cables. By folding and stacking them, combined with mounting columns of different heights for fastening, the module volume is compressed and heat accumulation is reduced. At the same time, fill light windows are set on both sides of the viewfinder to improve fill light brightness and image quality.
This resulted in a more compact module size, improved heat dissipation, higher and more uniform illumination, and improved image acquisition quality.

Various barcode reading devices of different sizes and functions have emerged in the market. Because the realization of barcode reading module functions involves multiple structural functional modules such as optics, image processing, and signal transmission, its internal structure is complex and the number of various components is huge.
[0003] For barcode reading modules that can be embedded in other large devices, smaller size and superior reading capabilities are undoubtedly the most important highlights. However, the compact structure of small modules results in relatively weak heat dissipation. Utility Model Content

It uses flexible flat cables to connect a main control board, conversion board, and acquisition board with different functions. The main control board, conversion board, and acquisition board are then stacked by folding. Simultaneously, mounting posts of different heights are used to secure the overall structure, compressing the module's volume and making the overall design more compact. Furthermore, since the main control board and acquisition board are not on the same board surface, localized heat accumulation is reduced, and the certain stacking gaps also improve overall heat dissipation.

[0013] 1. This utility model uses flexible flat cables to connect main control boards, conversion boards and acquisition boards with different functions, and then stacks the main control boards, conversion boards and acquisition boards by folding.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a stacked barcode reading module, including a base 1 and a circuit board 2 and a data acquisition board 3 detachably disposed inside the base 1. A viewfinder window 11 is provided in the middle of the front of the base 1. The viewfinder window 11 has an annular stepped concave structure. A supplementary lighting window 12 is provided on both sides of the viewfinder window 11. The design of the double supplementary lighting window 12 makes the supplementary lighting bright and uniform without dead angles. A storage slot 13 is provided on the back of the base 1 for placing the circuit board 2 and the data acquisition board 3. Two partitions 14 are provided in the storage slot 13.

[0024] As a further preferred embodiment, the circuit board 2 includes a main control board 21 and a conversion board 22, with a first flexible flat cable 4 connecting the main control board 21 and the conversion board 22. The main control board 21 includes a control module, a storage module, and a first interface module. The conversion board 22 includes a power module and a second interface module. A second flexible flat cable 5 connects the second interface module of the conversion board 22 and the acquisition board 3. The flexible flat cable connects the rigid boards with different functions, and the overall structure is secured by folding and mounting posts of different heights, which compresses the module volume and makes the overall module design more compact. At the same time, since the main control board 21 and the acquisition board 3 are not on the same board surface, the local heat accumulation is reduced.
[0025] As a further preferred embodiment, the connection between the main control board 21 and the conversion board 22 is reinforced with reinforcing adhesive, and the connection between the conversion board 22 and the acquisition board 3 is also reinforced with reinforcing adhesive to avoid repeated bending during installation or maintenance that could cause the circuit to break.
[0026] As a further preferred embodiment, the acquisition board 3 includes a lens component and a supplementary lighting component, and the lens component and the supplementary lighting component are connected by a flexible plate, that is, the lens component and the supplementary lighting component are connected by a flexible circuit board.
[0027] As a further preferred embodiment, long mounting posts 15 are provided at two opposite corners of the back of the base 1, and short mounting posts 16 are provided at the other two opposite corners of the back of the base 1. The acquisition plate 3 is embedded in the storage slot 13, and the lens component is adapted to the viewfinder window 11.

The main control board 21 is provided with a second positioning hole 211 corresponding to the long mounting post 15 at its opposite corner. The second positioning hole 211 of the main control board 21 is connected to the long mounting post 15 by screws. The design of the long mounting post 15 and the short mounting post 16 facilitates the installation and fixation of the main control board 21 and the conversion plate 22, and also controls the distance between the main control board 21 and the conversion plate 22. The overlapping gaps improve the overall heat dissipation capacity and ensure a certain heat dissipation effect.
[0028] Working principle of this utility model:
[0029] During assembly, the acquisition board 3 is first embedded into the storage slot 13 on the back of the base 1. Then, the conversion board 22 is locked onto the short mounting post 16 of the base 1 with screws. Finally, the main control board 21 is locked onto the long mounting post 15 at the opposite corner of the base 1 with screws. The main control board 21, conversion board 22 and acquisition board 3 with different functions are connected by flexible flat cables. The main control board 21, conversion board 22 and acquisition board 3 are stacked by folding. At the same time, the overall structure is secured with mounting posts of different heights, which compresses the module volume and makes the overall module design more compact. At the same time, since the main control board 21 and acquisition board 3 are not on the same board surface, the local heat accumulation is reduced, and the certain stacking gap also improves the overall heat dissipation capacity.
