[0015] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention will now be further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the relevant components of the present invention.

[0016] According to the technical solution of the present invention, without changing the essential spirit of the present invention, those skilled in the art may propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are merely illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0017] The technical solution of the present utility model is further described in detail below with reference to the accompanying drawings and embodiments.

[0018] Example 1, as Figure 1 As shown, a compatible image-type code scanning device includes an upper cover 1 and a lower cover 12. The upper cover 1 is fixed to the lower cover 12 by snapping. A first circuit board 11 is installed at the bottom of the inner cavity of the lower cover 12, and a second circuit board 13 is installed in the middle of the inner cavity of the lower cover 12. The two circuit boards are used to realize different illumination methods, such as atomized code scanning, polarized code scanning, and direct code scanning, so that they are suitable for different working scenarios.

[0019] A lens module 5 is mounted in the center of the upper portion of the lower cover 12's interior through a lens hood 6. Scanning and illuminating the barcode primarily relies on this lens module 5. A polarizing plate 4 is mounted on top of the lens module 5, through which the light emitted by the lens module 5 is emitted, allowing for use in polarized scenarios. LED light panels 7 are mounted on either side of the upper portion of the lower cover 12's interior. These panels are connected to atomizing plates 3 through the lens hood 6 to atomize the illuminated light.

[0020] The first circuit board 11 is connected to the LED light board 7 through a circuit, and the second circuit board 13 is connected to the lens module 5 through a circuit. According to different application scenarios, the first circuit board 11 controls the LED light board 7 to scan the code through the atomizer plate 3, and the second circuit board 13 controls the lens module 5 to scan the code through the polarizer.

[0021] In addition, a mounting frame is provided on the top of the upper cover 1, and a front window glass 2 is installed inside the mounting frame. The front window glass 2 is transparent, which is convenient for polarized light and atomized optical fiber to pass through, and is also used to protect the internal structure.

[0022] A cable 10 is mounted on one side of the bottom of the lower cover 12. A step is provided at the connector of the cable 10, and a cable seal 9 is mounted on the step to secure the connector. Since the cable 10 is often pulled during use, installing the cable seal 9 also helps to alleviate some of the pulling and friction at the connector.

[0023] In Example 2, based on Example 1, the first circuit board 11 is secured to the bottom of the lower cover 12 via brackets at the bottom of the cavity. The second circuit board 13 is secured to the middle of the cavity of the lower cover 12 via brackets protruding from the outer periphery of the bottom of the cavity. The second circuit board 13 is located on top of the first circuit board 11. Therefore, both circuit boards are supported by brackets pre-set on the cavity of the lower cover 12. Both circuit boards are conventional components. However, in the prior art, the first circuit board 11 is used for atomized code scanning, while the second circuit board 13 is used for polarized code scanning.

[0024] The brackets at the bottom of the inner cavity of the lower cover 12 are designed and retained during injection molding. Draft angles are set at the corners of the brackets to facilitate ejection. With existing scanning equipment that separately implements polarization and atomization, the first circuit board 11 uses a PCBA board, and the second circuit board 13 uses a CMOS board. In this solution, the two illumination methods are integrated.

[0025] The lens module 5 is fixed to the upper part of the second circuit board 13 by screws, and the polarizing plate 4 is fixed directly above the lens module 5 in a wrapped shape by a support frame, making the entire structure more compact and reasonably utilizing the inner cavity space of the lower cover 12.

[0026] Example 3, based on Example 1, has grooves formed around the top mounting surface of the lower cover 12, into which the sealing ring 8 is mounted. The bottom mounting surface of the upper cover 1 is provided with ridges matching the grooves. Once the ridges are locked into the grooves, screws can be installed to further secure the two.

[0027] As a preferred solution, the inner step of the groove is lower than the outer step of the groove, and the step has a supporting function. Specifically, the inner side of the LED light board 7 is installed on one side of the lens module 5, and the outer side of the LED light board 7 is installed on the inner step of the groove, providing support for the LED light boards 7 on both sides and facilitating installation.

[0028] Example 4, based on the scheme of Examples 1-3, can be implemented by the following operations:

[0029] Put the cable sealing gasket 9 on the step of the cable 10, and pass the cable 10 through the corresponding position of the lower cover 12 and fix the cable 10 with screws; fix the first circuit board 11 to the corresponding position inside the lower cover 10 with screws; fix the lens module 5 to the corresponding position of the second circuit board 13; install the second circuit board 13 on the top of the first circuit board 11 and fix it to the corresponding position inside the lower cover 10 with screws; fix the lens hood 6 to the corresponding position of the LED light board 7 with screws; clamp the sealing ring 8 in the corresponding slot of the lower cover 10; install the LED light board 7 on the second circuit board 13 and fix it on the lower cover 10 with screws; install the polarizing plate 4 and the atomizing plate 3 at the corresponding positions of the lens hood; fix the front window glass 2 inside the upper cover 1; fix the upper cover 1 to the corresponding position of the lower cover 12 with screws.

[0030] In summary, the present invention, through its internal structural design, secures the polarizing plate 4 and atomizing plate 3 to the lens shield 6. Using circuit boards with two conventional illumination modes, the LED light board 7 controls the illumination of different areas to adapt to the application environment, enabling barcode scanning and reading in various scenarios. By integrating the components required for atomization and polarization within the device, the device facilitates installation and operation, thus reducing production costs.

[0031] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
