The mounting module formed by the three circuit boards and the bracket can be easily assembled into the shell through the mounting port at the top, and the part mounting operation in the narrow space in the shell is omitted, so as to not only improve the assembly efficiency of the code reader, but also be easily disassembled during later maintenance.

[0047] First, refer to Figure 1 and Figure 2 , the figure shows the perspective structure and the exploded structure of the code reader provided by the embodiments of the present application, as shown in the figure, the code reader 100 comprises: a shell 110, a mounting module 120 and a cover plate 130. The top of the shell 110 is provided with a mounting port 111, the mounting module 120 can be placed in the shell 110 through the mounting port 111, and the cover plate 130 can be detachably provided at the mounting port 111. After assembly, the cover plate 130 and the shell 110 jointly protect the internal mounting module 120 and provide a good working environment for the mounting module 120. Specifically, the shell 110 and the cover plate 130 can be made of light plastic material to reduce the production cost of the code reader 100.

[0048] For the specific structure of the installation module 120, please further combine Figure 3 , the figure shows the three-dimensional structure of the installation module 120, which includes a bracket 121, an image acquisition board 122, a light source board 123 and a main board 124, the image acquisition board 122, the light source board 123 and the main board 124 are assembled on the bracket 121, for example, they can be assembled through threaded fasteners, clamping and other ways, the specific assembly method is not limited here.

[0049] As shown in Figure 1 and 2 , the side of the shell 110 adjacent to the top thereof is provided with a light-transmitting window 112, please further combine the cross-sectional structure of the bracket 121, the image acquisition board 122 and the light source board 123 shown in Figure 4 , the bracket 121 is provided with a light channel 1211, the image acquisition board 122 is connected to the side of the bracket 121 away from the light-transmitting window 112, the image acquisition board 122 is provided with a lens assembly 1221, specifically, the lens assembly 1221 can include a lens body 12211 and a lens bracket 12212, the lens bracket 12212 can be directly fixed on the surface of the image acquisition board 122 by adhesive, the lens body 12211 is fixed on the image acquisition board 122 through the lens bracket 12212, of course, the lens body 12211 can be fixed on the image acquisition board 122 by other assembly methods, which are not limited here.

[0050] The lens assembly 1221 is located in the light channel 1211, and the lens assembly 1221 is used to obtain the code reading image through the light channel 1211 and the light-transmitting window 112. The light source board 123 is connected to the side of the bracket 121 facing the light-transmitting window 112, and the light source board 123 is arranged to avoid the light channel 1211, and the light source board 123 is provided with a light supplement lamp 1231, which is used to supplement light for the shooting area of the lens assembly 1221.

[0051] As shown in Figure 4 , in the image acquisition module composed of the bracket 121, the image acquisition board 122 and the light source board 123, on the basis of installing the image acquisition board 122 and the light source board 123 on both sides of the bracket 121, the light channel 1211 is opened on the bracket 121 for the lens assembly 1221 on the image acquisition board 122 to extend into it, so that the lens assembly 1221 can collect images through the light-transmitting window 112 to obtain the code reading image, while minimizing their size in the arrangement direction between the image acquisition board 122 and the light source board 123 (i.e. the horizontal direction in Figure 4 ) to meet the demand of product miniaturization.

[0052] As shown in Figure 3As shown, the motherboard 124 is connected to the bracket 121, specifically through threaded fasteners, snap-fit ​​connections, or other methods of assembly. Figure 5 As shown, the motherboard 124 is electrically connected to the image acquisition board 122 and the light source board 123 respectively. The motherboard 124 is used to control the image acquisition board 122 to acquire images and to control the light source board 123 to flash at the same frequency for supplementary lighting. In addition, the motherboard 124 can also be further connected to the external device 200 through the external expansion cable 210 for signal and image transmission, etc.

[0053] During assembly, the image acquisition board 122, the light source board 123, and the main board 124 are first installed and fixed on the bracket 121 to form the mounting module 120. Then, the mounting module 120 is inserted into the housing 110 through the mounting port 111. Finally, the cover plate 130 is placed on the mounting port 111 to complete the overall assembly of the code reader 100. The entire assembly process is convenient and easy to disassemble and maintain later.

[0054] Furthermore, in the barcode reader 100 provided in this application embodiment, the image acquisition board 122, the light source board 123 and the main board 124, which are uniformly installed on the bracket 121, are electrically connected to form a complete internal circuit structure. The layout of the entire internal circuit structure is concise and compact and easy to disassemble and maintain, thereby reducing the production cost and subsequent maintenance cost of the barcode reader 100 while achieving effective barcode reading.

[0055] To facilitate accurate and efficient alignment of the lens assembly 1221's shooting area with the barcode to be scanned during use, this application further incorporates corresponding designs for the alignment of the shooting area. Please refer to the details below. Figure 6 The figure shows Figure 4 As shown in the magnified structure at point A, a positioning light 1222 is provided on the side of the image acquisition board 122 facing the bracket 121. A light-transmitting hole 1212 and a lens 1213 are provided on the bracket 121 opposite to the positioning light 1222. The light-transmitting hole 1212 is located between the positioning light 1222 and the lens 1213. The light emitted by the positioning light 1222 is... Figure 6 The dashed line indicates that the light-transmitting hole 1212 is used to supply light emitted by the positioning light 1222 located on the optical axis. Figure 6 A portion of the light rays near the midpoint (as shown by the dashed line) pass through and reach the lens 1213. That is, after the light emitted by the positioning light 1222 is intercepted by the light-transmitting hole 1212, the relatively uniform light rays in the center will pass through the light-transmitting hole 1212 and reach the lens 1213. The remaining light rays are blocked by the bracket 121 to ensure that the final light spot has high brightness and uniform distribution.

[0056] The lens 1213 is used to focus the light rays reaching it and output the focused light rays, so that the output light rays can form a bright spot on the object plane (i.e., the surface of the object on which the barcode is located) captured by the lens assembly 1221, and then the person scanning the code can determine the range corresponding to the captured area of the lens assembly 1221 in the actual scene based on the position of the bright spot and the relative position relationship between the positioning lamp 1222 and the lens assembly 1221 inside, so as to quickly determine the field of view of the code reader 100.

[0057] In order to make the layout between the image acquisition board 122 and the support 121 more compact and the overall size smaller, further, as shown in Figure 6 The two sides of the support 121 are oppositely provided with a lamp bead groove 1214 and a lens groove 1215, the groove bottoms of the lamp bead groove 1214 and the lens groove 1215 are mutually penetrated through the light transmission hole 1212, the positioning lamp 1222 extends into the lamp bead groove 1214, and the lens 1213 is embedded in the lens groove 1215, so that the internal space of the lamp bead groove 1214, the light transmission hole 1212 and the lens groove 1215 forms a path for light output.

[0058] In this embodiment, after the image acquisition board 122 is assembled on the support 121, the positioning lamp 1222 extends into the lamp bead groove 1214 on the support 121, which not only protects the positioning lamp 1222, but also makes the overall layout more compact and has a smaller size in the arrangement direction between the image acquisition board 122 and the light source board 123. Embedding the lens 1213 in the lens groove 1215 also achieves the effect of compact layout and small size, finally making the code reader 100 meet the product miniaturization demand.

[0059] In order to more accurately find the center of the field of view of the code reader 100, as shown in Figure 4 The positioning lamp 1222 can be provided as multiple and distributed on at least two sides of the lens assembly 1221, for example, as shown in Figure 4 The positioning lamp 1222 can be provided as multiple and distributed on at least two sides of the lens assembly 1221, for example, as shown in

[0060] Considering that the image acquisition board 122 is provided with the lens assembly 1221, and in further embodiments, the positioning lamp 1222 can also be installed, the installation position and stability of these elements will directly affect the code reading effect, therefore, in order to balance the convenience and stability of the assembly between the image acquisition board 122 and the support 121, the present application proposes a specific implementation, please refer to Figure 3 andFigure 4 The bracket 121 and the image acquisition board 122 are positioned and engaged by positioning posts 1216 and positioning holes 1223, and are fixedly connected to each other by the first fastener 141. Specifically, it can be... Figure 4 As shown, a positioning post 1216 is provided on the bracket 121, and a positioning hole 1223 is provided on the image acquisition plate 122. Alternatively, the positioning post 1216 can be provided on the image acquisition plate 122, and a positioning hole 1223 can be provided on the bracket 121. Regardless of the method, during assembly, the positioning post 1216 is first inserted into the positioning hole 1223 to ensure that the connection hole on the image acquisition plate 122 and the bracket 121 are aligned. Then, the first fastener 141 is screwed into the connection hole to easily and reliably fix the image acquisition plate 122 and the bracket 121.

[0061] The specific location and quantity of the first fastener 141 can be set as needed, for example, as follows: Figure 4 As shown, the image acquisition board 122 is fixedly connected to the bracket 121 on opposite sides by two first fasteners 141. This reduces the number of first fasteners 141, making operation easier while ensuring the stability of the connection between the image acquisition board 122 and the bracket 121, thus providing a guarantee for subsequent code reading work.

[0062] Since the light source board 123 only serves as supplementary lighting, the stability of its own structure has little impact on the implementation of the code reading function. Therefore, in order to fully ensure the assembly efficiency of the code reader 100, such as Figure 3 and Figure 4 As shown, the light source board 123 can be fixed to the bracket 121 by snap-fit. Specifically, a buckle 1217 can be provided on the bracket 121, and the light source board 123 is snap-fitted and fixed to the bracket 121 by the buckle 1217.

[0063] For the assembly between cover plate 130 and housing 110, please refer again. Figure 2 As shown in the figure, one edge of the cover plate 130 can be engaged with the housing 110 for limiting, and the other edge of the cover plate 130 can be fixedly connected to the housing 110 by a second fastener 142. Specifically, a locking block 131 can be provided on one edge of the cover plate 130, and a slot is provided on the edge of the mounting opening 111 on the housing 110 corresponding to the locking block 131. Figure 2 (Not shown due to obstruction from view) During assembly, first insert the clip 131 into the slot, then fasten the cover plate 130 onto the housing 110 to initially fix the cover plate 130 and the housing 110. Next, insert the second fastener 142 into the connecting hole on the cover plate 130 and the housing 110 and tighten it to assemble the cover plate 130 and the housing 110. The whole assembly process is simple and easy to operate.

[0064] In order to ensure the stability of the assembly of the cover plate 130 and the shell 110, in the specific embodiment shown in the drawings, the side edges of the cover plate 130 are clamped by the blocks 131 near the two ends, and the second fasteners 142 are connected at the two ends of the cover plate 130 opposite the other side edges, thereby fixing the cover plate 130 and the shell 110 at the four corners to ensure the reliability of the connection between the two. Figure 2 In the specific embodiment shown in the drawings, the side edges of the cover plate 130 are clamped by the blocks 131 near the two ends, and the second fasteners 142 are connected at the two ends of the cover plate 130 opposite the other side edges, thereby fixing the cover plate 130 and the shell 110 at the four corners to ensure the reliability of the connection between the two.

[0065] Of course, in other embodiments, the cover plate 130 and the shell 110 can also be fixed by snap-fit to make the disassembly and assembly of the two more convenient and fast.

[0066] Considering that after the cover plate 130 and the shell 110 are assembled and fixed by the second fasteners 142, the second fasteners 142 will inevitably be exposed on the surface of the cover plate 130, thereby affecting the neatness and aesthetics of the appearance of the code reader 100, in combination with Figure 1 and Figure 2 , the outer side of the cover plate 130 can be further provided with a decorative plate 150, which covers the second fasteners 142 to make the product appearance neat and beautiful. The decorative plate 150 can be made of an economical and practical decorative Mylar (i.e., PET polyester film) to reduce the cost of the product while ensuring durability.

[0067] Further, in order to improve the waterproof and dustproof performance of the product, as shown in Figure 2 , the edge of the mounting port 111 can also be provided with a sealing ring 113, which is pressed tightly after the cover plate 130 is covered on the mounting port 111, so that the assembly gap between the cover plate 130 and the shell 110 is sealed, thereby achieving the waterproof and dustproof effect.

[0068] The code reader usually has keys configured to control it. For the code reader 100 provided by the embodiments of the present application, considering that the internal circuit is mainly composed of the installation module 120 as a whole, and the installation module 120 will be uniformly installed in the shell 110 after being completely assembled, if the keys are provided on the shell 110, it is difficult to determine whether the keys on the shell 110 and the contacts on the installation module 120 are aligned after the installation module 120 is installed, which can easily cause the keys to fail to function normally, affecting the product qualification rate.

[0069] To this end, the present application provides a solution, which is described in detail in Figure 2The main board 124 can be arranged in parallel with the plane where the mounting port 111 is located, and the main board 124 is provided with switch contacts 1241, and the cover plate 130 is provided with a button 132 at a position opposite to the switch contacts 1241, the button 132 is pressed to trigger the switch contacts 1241 to control the image acquisition board 122 and the light source board 123 to work, and the specific number and position of the button 132 and the switch contacts 1241 can be set according to actual functional requirements. In the specific embodiment shown in the figure, the button 132 is provided with one, which mainly plays a tuning function, that is, after the button 132 is pressed, the code reader 100 automatically tunes and triggers the photographing to read the code.

[0070] In the embodiment, the button 132 is first arranged on the cover plate 130, and then the main board 124 is arranged in parallel with the plane where the mounting port 111 is located, so that the button 132 on the cover plate 130 can trigger the switch contacts 1241 on the main board 124 when pressed, thereby ensuring the function implementation after the button 132 is arranged on the cover plate 130. By arranging the button 132 on the cover plate 130, the alignment of the switch contacts 1241 and the button 132 does not need to be considered during the operation of installing the mounting module 120 into the shell 110, and the two need to be aligned only when the cover plate 130 is assembled, and during the process of the cover plate 130 being buckled on the mounting port 111, the alignment of the two can be observed more easily, and the position of the mounting module 120 is adjusted according to the alignment accuracy to ensure that the alignment requirement is met after assembly.

[0071] In addition, as shown in Figure 2 and Figure 3 , the main board 124 can also be provided with an indicator light 1242, and the cover plate 130 is provided with a light-transmitting portion 133 at a position opposite to the indicator light 1242, the light-transmitting portion 133 is used for the light emitted by the indicator light 1242 to pass through, thereby realizing the feedback of the corresponding function.

[0072] The number and position of the indicator light 1242 can also be set according to actual requirements, in the specific embodiment shown in the figure, the indicator light 1242 is provided with three, which are respectively used to display the feedback of the power supply state, the system state and the network connection state.
