The scanning device comprises a shell 10, a light distribution cover 20, a code scanning piece 30 and a light supplementing piece 40; the following are described separately.

Referring to fig. 1 to 3 and 5 to 7, the outer casing 10 includes a bottom case 11 and a cover 12; the cover plate 12 may be made of a transparent glass material or a transparent acrylic material, and may be configured to cover the port of the bottom case 11 by bonding, welding, fastening, locking, and the like, so as to construct a casing space capable of accommodating the light distributing cover 20, the code scanning member 30, and the light compensating member 40 inside the outer casing 10; meanwhile, a scanning window 10a is constructed on the side wall of the outer shell 10 by using the cover plate 12, so that the supplementary light emitted by the light supplement member 40 can irradiate the target area of the medium carrier through the scanning window 10a, and an illumination condition is created for the code scanning member 30 to acquire the image information of the target area.

Referring to fig. 2, 3, 5, 6 and 7, the light distribution cover 20 includes a light transmissive cover 21 and a light shielding cover 22; the light-transmitting cover 21 is arranged facing the scanning window 10a and covers the scanning window 10a, and is mainly used for homogenizing the supplementary light rays emitted by the light-compensating piece 40, so that the supplementary light rays can uniformly penetrate through the scanning window 10a and finally irradiate a target area of a medium carrier to achieve the effect of light homogenization; the light-shielding cover 22 is disposed on a side of the light-transmitting cover 21 away from the scanning window 10a, and covers the light-transmitting cover 21, and is mainly used for directionally condensing the supplementary light emitted by the light-compensating member 40 toward the area of the scanning window 10a, so as to prevent the light from irradiating other positions of the inner space of the outer shell 10.

In one embodiment, referring to fig. 2, 3, 5, 6 and 7, the overall outline of the light-transmissive cover 21 generally presents a structure similar to a cup shape, which has two opposite surfaces, i.e., for convenience of description, an inner side surface (or inner surface of the cup) of the light-transmissive cover 21 is defined as a first surface, and an outer side surface (or outer surface of the cup) of the light-transmissive cover 21 is defined as a second surface; wherein, the first surface is arranged facing the scanning window 10a and presents a concave structure depressed towards the direction of the second surface; a mounting opening 20a penetrating through the first surface and the second surface is arranged at the central position of the light-transmitting cover 21 so as to provide a structural space for assembling the code scanning piece 30 on the light distribution cover 20; meanwhile, the portion of the second surface surrounding the assembling opening 20a (i.e. the portion corresponding to the cup bottom edge) protrudes in the direction away from the scanning window 10a, so as to form a protruding structure 20b on the transparent cover 21, and by virtue of the morphological feature that the protruding structure 20b protrudes from the second surface, the transparent cover 21 is formed into a structural form similar to an optical lens, and when light enters the transparent cover 21 through the protruding structure 20b, the light can be diffused and transmitted in the transparent cover 21 along the protruding structure 20b, so as to be uniformly emitted from the light distribution cover 20.

In one embodiment, referring to fig. 2, 3, 6 and 7, the light-shielding cover 22 is a cup-shaped structure with a fixed shape, which substantially matches the contour of the second surface side of the light-transmitting cover 21 and is disposed on the second surface side of the light-transmitting cover 21 in a cover manner, so that the light-transmitting cover 21 can be accommodated in the light-shielding cover 22; the light shield 22 is fixed to the outer housing 10 near the edge (or the rim of the cup) of the scanning window 10a, for example, fixed to the sidewall of the port of the bottom housing 11 by screw locking, clipping, welding or adhering, and the rim of the cup of the light shield 21 can be fixed to the light shield 22 to form the split light distribution cover 20. In other embodiments, the light shield 22 may be coated or coated on the second surface of the light transmissive cover 21, so as to form the integrated light distribution cover 20 together with the light transmissive cover 21.

Referring to fig. 2, 3, 4, 6 and 7, the code scanning device 30 includes an image recognition device 31 and a radio frequency recognition device 32; the image recognition component 31 is mainly used for acquiring image information containing an identification code, so as to recognize information contained in the identification code through analysis processing of the image information; the rfid 32 is mainly used to identify the rfid and obtain an identification code associated with the rfid, so as to provide support for finally obtaining information contained in the identification code.

In one embodiment, referring to fig. 2, 3, 4, 6 and 7, the image recognition component 31 is disposed through the mounting opening 20a, and includes an image sensor 311, an optical lens 312, an image processor 313 and other components as required; the image sensor 311 is disposed through the assembly opening 20a and configured to acquire image information including an identification code; the image processor 313 is disposed on the light shield 22 and on the backside of the image sensor 311, and is mainly configured to identify the identification code in the image information containing the identification code, and send the identified identification code information to the outside, so as to obtain the identification result finally; the optical lens 312 is disposed on the sensing side of the image sensor 311 and directly faces the central region of the scanning window 10a, so that when the image sensor 311 acquires an image, the recognition distance of the image sensor 311 can be reduced by the optical lens 312, and the image sensor 311 can acquire clearer image information.

In one embodiment, referring to fig. 3, 4 and 8, the rfid component 32 may be an NFC module, wherein the antenna portion of the NFC module is disposed to be attached to the bottom sidewall (i.e., the sidewall opposite to the scanning window 10 a) of the bottom shell 11 and extend to the sidewall adjacent to the bottom sidewall. As is known, the NFC module applies a near field communication technology, and when an NFC-enabled device (such as a mobile phone, an NFC-compatible IC/ID card, an electronic tag, or the like) is close to an area where an antenna portion of the radio frequency identification component 32 is located, the radio frequency identification component 32 may exchange related data with the device, so as to obtain identification code information associated with the radio frequency tag; by selecting the arrangement position of the radio frequency identification piece 32, the induction area of the scanning device to the radio frequency label can be enlarged, and conditions are created for improving the code scanning identification efficiency. It should be noted that: the hatched portion in fig. 8 represents the layout area of the antenna portion of the rfid 32. Of course, in other embodiments, the rfid 32 may be implemented with other types of rfid card reading modules.

Referring to fig. 2, fig. 3, fig. 4, fig. 6 and fig. 7, the light supplement component 40 is mainly used for supplementing light when the code scanning component 30 (specifically, the image recognition component 31) acquires image information, so as to uniformly irradiate a target area of the medium carrier under the cooperation of the light distribution cover 20, so that the image recognition component 31 can quickly and accurately acquire the image information containing the recognition code. The light compensating element 40 is distributed around the image sensor 311 on a side of the light distributing cover 20 away from the scanning window (specifically, on a side of the second surface of the light transmitting cover 21), and a top end surface of the protrusion structure 20b (which is equivalent to a position where the light transmitting cover 21 is farthest from the scanning window) is arranged right opposite to the light emitting surface of the light compensating element 40, so as to cover the light emitting surface of the light compensating element 40, so that the light compensating light emitted by the light compensating element 40 can enter the light transmitting cover 21 through the convex top surface of the protrusion structure 20b to the maximum extent, and then propagates in the light transmitting cover 21. In specific implementation, the light compensating member 40 may select an integral lamp strip or an individual lamp bead according to the number, the structural form, and the like of the protruding structures 20 b.

Firstly, by means of the convex structure 20b on the light distribution cover 20, the supplementary light emitted by the light supplement part 40 can be uniformly emitted and spread in the light distribution cover 20 along the morphological characteristics of the convex structure 20 while being maximally incident into the light distribution cover 20, so that the target area of the medium carrier is uniformly irradiated through the scanning window 10a, the uniformity of light in the target area is ensured, the image recognition part 31 can rapidly and accurately acquire the reflected image, and favorable conditions are created for improving the success rate and efficiency of code scanning recognition.

Secondly, with the help of the light shielding effect of the light shield 22, the light source device not only can perform directional light focusing effect on the light supplementing light towards the light transmitting cover 21 and the area of the scanning window 10, but also can shield other positions of the internal space of the device from being irradiated by the light, thereby effectively improving the light utilization rate.

Thirdly, the scanning device can be configured as a portable scanning device, such as a handheld scanner, by selecting the functional configuration and the structural configuration (such as the structural configuration of the outer shell 10) of the scanning device; it can also be configured as a stationary scanning device, effectively extending the range of applications of the scanning apparatus.

In one embodiment, referring to fig. 5, the protrusion structure 20b includes a plurality of protrusions, such as three, four or more protrusions, spaced around the assembling opening 20 a; the contour of the convex part is approximately hump-shaped, the peripheral surface of the convex part smoothly transits to the second surface of the light-transmitting cover 21 and the edge of the assembly opening 20a, and each convex part is opposite to a light compensating part 40; the diffuse transmission structure 20c is arranged on the convex top surface of the convex part (namely, the convex top surface of the convex structure 20 b), the diffuse transmission structure 20c can be a structural surface processed by special processes such as surface grinding, sanding, atomization and the like, for example, the structural surface can comprise a plurality of quadrangular pyramid-shaped salient points, and the salient points are arranged in an array form, so that a diffuse reflection structure 20e is formed; the diffuse reflection structure 20e may also be a transmission material layer with a rough surface. The light-emitting surface of the light supplement component 40 is covered by the diffuse reflection structure 20e, so that light supplement light can enter the light distribution cover 20 and uniformly disperse and propagate in the light distribution cover 20, and the dazzling degree of light irradiating a target area of the medium carrier is finally relieved, so that the illumination of the target area is more uniform and softer.

In one embodiment, referring to fig. 2, 3, 5, 6 and 7, the edge of the light-transmissive cover 21 (i.e., the rim of the cup opening of the light-transmissive cover 21) is provided with two, three or more first fixing structures 23 in a substantially barb shape; correspondingly, the edge of the light shield 22 (i.e. the rim of the cup mouth of the light shield 22) is provided with a second fixing structure 24 with a generally bayonet shape, which is aligned with the first fixing structure 23 one by one; when the light-transmitting cover 21 and the light-shielding cover 22 are assembled, the first fixing structure 23 can be clamped or hooked on the corresponding second fixing structure 24 in an aligned manner, so that the light-transmitting cover 21 and the light-shielding cover 22 are fixedly connected; after the cover plate 12 of the outer casing 10 is covered on the bottom casing 11, the first fixing structures 23 are distributed around the contour of the scanning window 10 a; because the connecting position of the light-transmitting cover 21 and the light-shielding cover 22 is hidden at the periphery of the scanning window 10a, the interference to the illumination effect of the scanning window 10a and the target area of the medium carrier can be reduced; for example, occurrence of a dark shadow or the like on the sensing surface side of the image recognizing member 31 can be prevented.

In other embodiments, the first fixing structure 23 and the second fixing structure 24 may be configured in other manners to fix the light-transmissive cover 21 and the light-shielding cover 22 by bonding, snapping, welding, locking, etc. based on the selected arrangement of the cover plate 11 and the scanning window 10 a.

The control module 50 is packaged in the bottom shell 11 through the cover plate 12, and mainly plays a role in coordination control of related functional components; for example, the luminous intensity of the light compensating member 40 is automatically adjusted according to the type of the medium carrier and the illumination condition of the environment where the medium carrier is located; for another example, the code scanning element 30 is controlled to execute its functional actions according to the input control command; meanwhile, the control module 50 also functions to receive the image information and/or the identification code acquired by the code scanning component 30, and finally acquire the identification result by identifying the information contained in the identification code. In specific implementation, the control module 50 may mainly include a circuit board 51 and related functional components integrated on the circuit board 51.

The communication module 60 includes at least one of an LPWAN module, a 2G communication module, a 3G communication module, a 4G communication module, a 5G communication module, a Wifi communication module, a bluetooth communication module, and a ZigBee (ZigBee protocol) module; in specific implementation, in order to ensure continuity and stability of data communication between the scanning device and the outside, the communication module 60 may be formed by combining the aforementioned multiple communication modules, so as to prevent a failure of one or more communication modules, and still ensure smooth data communication, and remove the limitation of the application environment on the communication of the scanning device. And the antenna part of each communication module can be selectively disposed in the outer case 10 or on the outer case 10 according to the respective characteristics.

The interaction module 70 mainly performs a human-computer interaction function, such as inputting a preset instruction (including but not limited to confirmation of a control command, setting and switching of functions, etc. for the scanning device); and also for example, the identification result output by the control module 50 or the image information acquired by the image identification component 31.
