Description

Technical Field

[0001] This application relates to the field of machine vision technology, and in particular to a barcode reader camera. Background Technology

[0002] To meet the needs of barcode scanning, barcode cameras generally require the installation of supplementary lighting. However, traditional barcode cameras either highly integrate the supplementary lighting with the internal components, making it impossible to replace, or although the integration is less complete, the power supply lines for the supplementary lighting and other power lines are all routed inside the camera, making them difficult to distinguish. When replacing the supplementary lighting, users must manually organize the power lines, identify the power supply lines for the supplementary lighting, remove the old supplementary lighting and its corresponding power lines, and then install the new supplementary lighting and its power lines inside the barcode camera. This process is prone to errors that can lead to cable breakage, resulting in difficulties for users and a long processing time. Utility Model Content

[0003] The purpose of this application is to provide a barcode reader camera that solves the problem of barcode reader cameras having an inability to replace the supplementary light source or difficulties in replacement. The specific technical solution is as follows:

[0005] In some embodiments, the top cover has a viewing window opening, and the top cover assembly further includes a camera window that covers the viewing window opening and is connected to the top cover, the camera window being located outside the supplementary light source assembly.

[0006] In some embodiments, the top cover assembly further includes a light shield and a lens bracket, the light shield and the lens bracket being located between the camera window and the supplementary light source assembly, with the light shield being positioned close to the camera window, and the supplementary light source assembly pressing the light shield and the lens bracket against the top cover; the lens bracket has a second through hole for the lens to pass through, and a first lens corresponding to the first supplementary light, and the light shield has a third through hole for the lens to pass through and a fourth through hole corresponding to the first lens.

[0007] In some embodiments, the light-shielding member is interference-fitted with the lens holder.

[0008] In some embodiments, the light-shielding element is a flexible element.

[0009] In some embodiments, the lamp panel body includes a surface light source setting area located below the lens, the surface light source setting area is provided with a surface light source, the lens bracket is provided with an opening at a position opposite to the surface light source, and the light shield is located above the surface light source.

[0010] In some embodiments, the surface light source includes a plurality of second fill lights and a diffuser plate covering the second fill lights, wherein the second fill lights are evenly distributed at intervals in the surface light source.

[0011] In some embodiments, the upper cover has a protrusion that extends outward around the window opening to accommodate the camera window. The protrusion has a raised edge on its inner side, and the camera window is bonded to the side of the raised edge away from the lower housing. The light shield, the lens bracket, and the supplementary light source assembly are located on the side of the raised edge closer to the lower housing.

[0012] In some embodiments, the circuit board is provided with a positioning light source, which is located above the lens. The lamp board body, the lens bracket, and the light shield are sequentially provided with a fifth through hole, a second lens, and a sixth through hole corresponding to the positioning light source.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, this application embodiment provides a barcode reader camera, wherein, Figure 1 This is a diagram illustrating the normal placement of the barcode reader camera. Figure 2 This is a schematic diagram of the top cover assembly 10 in normal placement, meaning the top cover 11 is facing upwards. Figure 3This is a schematic diagram of the back structure of the light panel body. The barcode reader camera includes an upper cover assembly 10 and a lower shell assembly 20. The upper cover assembly 10 includes an upper cover 11 and a supplementary light source assembly 13. The supplementary light source assembly 13 is located inside the upper cover 11 and connected to the upper cover 11. Optionally, the supplementary light source assembly 13 and the upper cover 11 can be detachably connected to facilitate maintenance and installation of the upper cover assembly 10. The supplementary light source assembly 13 includes a light panel body 131 and at least one first supplementary light 132 disposed on the side of the light panel body 131 facing the upper cover 11. The light panel body 131 includes a first through hole 1311 through which a lens 221 passes, and a connector 1312 is provided on the side of the light panel body 131 facing away from the upper cover 11. The lower housing assembly 20 includes a lower housing 21 and a lens assembly 22, a power supply module (not shown in the figure), and a circuit board 23 located inside the lower housing 21. The lower housing 21 is detachably connected to the upper cover 11. The lens assembly 22 includes a lens 221. The circuit board 23 is provided with an interface 231 led out from the power supply module. The interface 231 is plugged and plugged into the connector 1312 so that the power supply module can supply power to the supplementary light source assembly 13.

[0026] In this embodiment, the supplementary light source assembly 13 includes a lamp board body 131 and a first supplementary light 132 disposed on the lamp board body 131. The lamp board body 131 has a built-in circuit for controlling the first supplementary light 132, and the lamp board body 131 is plugged into and electrically connected to the circuit board 23 inside the lower shell 21. Since the supplementary light source assembly 13 is integrated on the upper cover 11, it is used together with the upper cover 11 as part of the barcode reader camera. When replacing the upper cover 11, the supplementary light source assembly 13 can be replaced together, enabling the barcode reader camera to clearly read and recognize codes in different application scenarios, improving the success rate of code reading and enhancing the user experience. Moreover, the replacement process is simpler than that of traditional barcode readers, saving users time and reducing the risk of misoperation or cable breakage. Because the barcode reader can change the supplementary light source according to the application scenario, the barcode reader has a wider range of applications and better barcode recognition effect. For users with multiple needs, only different top cover components 10 are required, instead of multiple barcode readers. This can also reduce user costs and help increase the market share of barcode readers.

[0027] In this embodiment, the supplementary light source assembly 13 is located inside the upper cover 11, meaning it is built-in and integrated with the upper cover 11 as part of the barcode reader camera. Therefore, this embodiment allows for quick replacement of the built-in supplementary light source. Compared to an external supplementary light source, a built-in supplementary light source allows for a simpler electrical connection structure and a smaller overall size of the barcode reader camera. Furthermore, compared to an external supplementary light source, a built-in supplementary light source reduces the number of sealing points in the barcode reader camera, allowing for a higher level of sealing.

[0028] The top cover 11 can be made of any acceptable material, such as polycarbonate, acrylic, and the like. At least the portion of the top cover 11 opposite the lens 221 is transparent, allowing the lens 221 to take pictures through the top cover 11.

[0029] In some embodiments of this application, the top cover 11 has a viewing window opening 111, and the top cover assembly 10 also includes a camera window 12, which covers the viewing window opening 111 and is connected to the top cover 11. The camera window 12 is located outside the supplementary light source assembly 13.

[0030] In this embodiment, the upper cover 11 has a viewing window opening 111, and the camera window 12 covers the viewing window opening 111. The lens 221 takes pictures through the camera window 12. The upper cover 11 acts as a frame, which makes it convenient to make the upper cover 11 and the camera window 12 from different materials. The camera window 12 is located outside the supplementary light source assembly 13. It can be located entirely inside the upper cover 11, or it can be located on the inner and outer sides of the upper cover 11 respectively. That is, the camera window 12 is located outside the upper cover 11, and the supplementary light source assembly 13 is located inside the upper cover.

[0031] The top cover 11 can be made of any acceptable material, whether transparent or colored. The camera window 12 is made of a transparent material, such as glass, acrylic, or sapphire. The camera window 12 and the top cover 11 can be integrally formed or separately formed. When integrally formed, the top cover 11 and the camera window 12 are preferably made of the same material for ease of molding. Preferably, the top cover 11 is made opaque to prevent internal parts from being seen through the top cover 11, thereby increasing the aesthetics of the barcode reader camera. Taking the top cover 11 and the camera window 12 as examples, the top cover 11 can be made opaque through processes such as frosting, printing, or inlaying. When separately formed, the top cover 11 and the camera window 12 can be made of different materials. The top cover 11 can be made of an opaque material, and the two can be bonded or screwed together.

[0032] Optionally, the first supplementary light 132 can be an LED lamp, fluorescent lamp, high-pressure sodium lamp, incandescent lamp, tungsten halogen lamp, or xenon lamp. Preferably, the first supplementary light 132 is an LED lamp, which has advantages such as high luminous efficiency, low voltage, and long lifespan. The color of the first supplementary light 132 can be white light, blue light, or full-color light. Preferably, the color of the first supplementary light 132 is white light, as white light is universal for acquiring various images and is suitable for the accurate acquisition of various types of images.

[0033] Optionally, such as Figure 1 and Figure 3 As shown, the connector 1312 of the lamp panel body 131 can be a pogogin (spring pin connector), board-to-board connector, socket, or other standard connector.

[0034] An optical functional layer can be set on the inner surface of the camera window 12 to achieve different optical effects. For example, the camera window 12 can be designed with an optical functional layer with polarization effect or an optical functional layer with anti-reflection effect, depending on the application scenario. The camera window 12 can contain any one of the above optical functional layers or a combination of both. The polarization effect functional layer can be designed with different polarization angles as needed, ranging from 0° to 180°, such as 45°, 90°, 120°, etc. Therefore, when replacing the top cover assembly 10, both the camera window 12 and the supplementary light source are replaced simultaneously, allowing for better adaptation to different application scenarios.

[0035] According to some embodiments of this application, such as Figure 2 As shown, the upper cover assembly 10 also includes a light-shielding member 15 and a lens bracket 14. The light-shielding member 15 and the lens bracket 14 are located between the camera window 12 and the supplementary light source assembly 13, with the light-shielding member 15 positioned close to the camera window 12. The supplementary light source assembly 13 presses the light-shielding member 15 and the lens bracket 14 firmly onto the upper cover 11. The lens bracket 14 has a second through hole 141 for the lens 221 to pass through, and a first lens 142 corresponding to the first supplementary light 132. The light-shielding member 15 has a third through hole 151 for the lens 221 to pass through, and a fourth through hole 152 corresponding to the first lens 142.

[0036] In this embodiment, the first lens 142 on the lens bracket 14 is positioned corresponding to the first supplementary light 132. It collimates the light emitted by the first supplementary light 132, converting the divergent beam into a parallel beam, thus concentrating the supplementary light source around the lens 221. The light-shielding member 15 is located above the lens bracket 14, and a fourth through-hole 152 is provided at the position corresponding to the first lens 142. This allows the supplementary light to be emitted through the fourth through-hole 152, while light illuminating other positions on the light-shielding member 15 is absorbed by it. This ensures the emission angle of the supplementary light and reduces the risk of light reflecting back after hitting the light-shielding member 15, thereby reducing the risk of interference with the lens 221's shooting. The light-shielding member 15 and the lens bracket 14 are pressed together on the upper cover 11 by the supplementary light assembly, simplifying the installation relationship between the light-shielding member 15 and the lens bracket 14.

[0037] Optionally, such as Figure 2As shown, the upper cover 11 has four cylindrical mounting portions 113, located near the four apex corners of the upper cover 11 and inside the protruding edge 1121 described below. Each cylindrical mounting portion 113 has a threaded hole, and the lens bracket 14 has a first mounting hole 148 at the corresponding position of the cylindrical mounting portion 113. Specifically, the first mounting hole 148 is an open mounting hole, meaning it is open on the side away from the interior of the lamp panel body 131. The lamp panel body 131 has second mounting holes 1313 at the corresponding positions of the cylindrical mounting portions 113. Two of the second mounting holes 1313 are closed mounting holes, and the other two are open mounting holes. This facilitates the insertion of the cylindrical mounting part 113 into the first mounting hole 148 and the second mounting hole 1313. After the cylindrical mounting part 113 is inserted, the lens bracket 14 and the lamp plate body 131 can be finely adjusted, which facilitates the fastener to engage with the threaded holes of the first mounting hole 148 and the second mounting hole 1313, thereby pressing the lens bracket 14 and the light shield 15 onto the upper cover 11 through the lamp plate body 131.

[0038] In some embodiments of this application, such as Figure 2 As shown, the light-shielding member 15 and the lens bracket 14 are interference-fitted. This interference fit simplifies the connection structure between the light-shielding member 15 and the lens bracket 14, and also simplifies the installation process. For example, the lens bracket 14 is provided with a first positioning post 143, and the light-shielding member 15 is provided with a first positioning hole 153 at the corresponding position. Through the interference fit between the first positioning hole 153 and the first positioning post 143, the installation of the light-shielding member 15 and the lens bracket 14 can be completed quickly.

[0039] like Figure 2 As shown, four first positioning holes 153 and four first positioning posts 143 are provided. Two of the first positioning posts 143 are located below the first through hole 1311 and on either side of the seventh through hole 146 (described below). The other two first positioning posts 143 are located above the first through hole 1311 and below the second lens 145 (described below). The first positioning holes 153 and the first positioning posts 143 are arranged opposite to each other. Therefore, two of the first positioning holes 153 are located below the third through hole 151 and on either side of the eighth through hole 155 (described below). The remaining two first positioning holes 153 are located above the third through hole 151 and below the sixth through hole 154 (described below).

[0040] like Figure 2 As shown, the lens bracket 14 and the lamp panel body 131 are first positioned and fitted together. The side of the lens bracket 14 facing the lamp panel body 131 is provided with a second positioning post (not shown in the figure). There can be two second positioning posts. The lamp panel body 131 is provided with a second positioning hole 1314 corresponding to the position of the second positioning post. The second positioning post and the second positioning hole 1314 cooperate to complete the pre-positioning installation of the lens bracket 14 and the lamp panel body 131.

[0041] In some embodiments of this application, the light-shielding member 15 is a flexible member. For example, the light-shielding member 15 can be a silicone member or the like, which facilitates inserting the light-shielding member 15 into the lens holder 14 and achieving an interference fit.

[0042] In some embodiments of this application, such as Figure 2 As shown, multiple first supplementary lights 132 are provided and evenly distributed around the lens 221. This makes the light brightness around the lens 221 more uniform, which is beneficial to improving the imaging effect of the barcode reader camera.

[0043] Optionally, the first supplementary light 132 can be four, six, or so. For example... Figure 2 As shown, when there are four first fill lights 132, they are located on the upper and lower sides of the lens 221 respectively, and the lines connecting them form a square.

[0044] In some embodiments of this application, such as Figure 2 As shown, the lamp panel body 131 includes a surface light source setting area 133 located below the lens 221. The surface light source setting area 133 is provided with a surface light source. The lens bracket 14 is provided with an opening 144 at a position opposite to the surface light source. The light shield 15 is located above the surface light source.

[0045] In this embodiment, a surface light source is positioned below the lens 221, specifically below the first through-hole 1311 of the light panel body 131, which further enhances the supplementary lighting effect of the barcode reader camera. Since the lens bracket 14 corresponds to the surface light source with an opening 144, and the light-shielding member 15 is located above the surface light source, the light emitted from the surface light source passes through the opening 144 and the camera window 12 to illuminate outwards, bypassing the converging effect of the lens. This results in a wider illumination angle for the surface light source, which is beneficial for providing wide-angle supplementary lighting to the product being photographed. Furthermore, since the light-shielding member 15 is located above the surface light source setting area 133, it eliminates the need for an opening 144 at the corresponding surface light source position, simplifying its structure. Moreover, the light-shielding member 15's location above the surface light source ensures that the light emitted from the surface light source is blocked by its lower edge, preventing it from entering the vicinity of the lens 221 and thus avoiding interference from the surface light source during image capture by the lens 221.

[0046] Optionally, the surface light source includes multiple second supplementary lights 1331 and a diffuser plate (not shown in the figure) covering the second supplementary lights 1331. The second supplementary lights 1331 are evenly distributed at intervals within the surface light source. The second supplementary lights 1331 can be LED lamps, fluorescent lamps, high-pressure sodium lamps, incandescent lamps, tungsten halogen lamps, or xenon lamps. Preferably, the second supplementary lights 1331 are LED lamps, which have advantages such as high luminous efficiency, low voltage, and long lifespan. The color of the second supplementary lights 1331 can be white light, blue light, or full-color light. The type of the second supplementary lights 1331 and the first supplementary light 132 can be the same or different.

[0047] The diffuser plate can homogenize the light emitted by the second fill light 1331, making the light brightness more uniform at different positions after passing through the diffuser plate. Therefore, it can present the characteristics of a surface light source and provide wide-angle fill light for the product to be photographed. Specifically, the diffuser plate can be located within the opening 144 of the lens bracket 14.

[0048] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the upper cover 11 has a protruding part 112 that is provided around the viewing window opening 111 and protrudes outward for accommodating the camera viewing window 12. The inner side of the protruding part 112 is provided with a protruding edge 1121. The camera viewing window 12 is bonded to the side of the protruding edge 1121 away from the lower shell 21. The light shield 15, the lens bracket 14 and the supplementary light source assembly 13 are located on the side of the protruding edge 1121 close to the lower shell 21.

[0049] In this embodiment, after the camera window 12 is bonded to the side of the protruding edge 1121 away from the lower shell 21, the periphery of the camera window 12 abuts against the inner side of the protrusion 112, so that the periphery of the camera window 12 is not exposed, and the protrusion 112 can play a role in protecting the camera window 12. The protruding distance of the protruding edge 1121 does not exceed the boundary of the window opening 111, so it will not affect the window range. The setting of the protruding edge 1121 makes it possible for the camera window 12 to be fixed by bonding with the protruding edge 1121, which is simple and easy to operate; on the other hand, when the supplementary light source assembly 13 presses the lens bracket 14 and the light shield 15, the protruding edge 1121 and the supplementary light source assembly 13 can easily form a clamping force, and the protruding edge 1121 can increase the contact surface with the light shield 15 and the lens bracket 14, reduce the pressure on the upper cover 11 and the light shield 15 and the lens bracket 14, and reduce the risk of stress concentration between them.

[0050] In some embodiments of this application, such as Figure 1 and Figure 2As shown, the circuit board 23 is provided with a positioning light source 232, which is located above the lens 221. The lamp board body 131, the lens bracket 14 and the light shield 15 are sequentially provided with a fifth through hole 1315, a second lens 145 and a sixth through hole 154 corresponding to the positioning light source 232.

[0051] By placing the alignment light source 232 on the circuit board 23, which is located below the supplementary light source assembly 13, the distance between the alignment light source 232 and the camera window 12 is lengthened, resulting in a more suitable size pattern presented by the alignment light source 232, making it easier to distinguish. The alignment light source 232 not only provides supplementary lighting but also enables the barcode reader to aim. When the barcode reader is reading a code, the alignment light source 232 can pre-determine the placement position of the product to be read, making subsequent code readings more likely to succeed on the first attempt. The second lens 145 can be a collimating lens, used to convert the light emitted from the alignment light source 232 into a parallel beam, ensuring that the pattern projected by the alignment light source 232 onto the target position does not diverge, thus making the placement of the product to be read more precise.

[0052] Optionally, such as Figure 1 As shown, the alignment light source 232 can be located above the lens 221, so the position of the fifth through hole 1315 on the lamp board body 131 is above the first through hole 1311, and the fifth through hole 1315 is located between and slightly above the two first supplementary lights 132 located above the lens 221.

[0053] In some embodiments of this application, a distance sensor 134 is provided on the lamp panel body 131, and the distance sensor 134 is disposed opposite to the fifth through hole 1315. The lens bracket 14 and the light shield 15 are respectively provided with a seventh through hole 146 and an eighth through hole 155 corresponding to the distance sensor 134.

[0054] The distance sensor 134 is placed on the light panel body 131, which, compared to placing it on the circuit board 23, allows it to be closer to the product to be read or photographed, resulting in more accurate distance measurement. By detecting the distance between the barcode reader camera and the product to be read or photographed through the distance sensor 134, the barcode reader camera can automatically focus, improving its working efficiency.

[0055] The distance sensor 134 is located below the lens 221 and can be positioned opposite to the sixth through hole 154 corresponding to the alignment light source 232 on the lamp panel body 131. The distance sensor 134 can be a single point or an array.

[0056] In some embodiments of this application, such as Figure 2As shown, the lamp panel body 131 is also provided with at least one indicator light 135, and the lens bracket 14 and the light shield 15 are respectively provided with a third lens 147 and a ninth through hole 156 corresponding to the indicator light 135.

[0057] By setting indicator lights 135, the working status of the barcode reader camera can be observed more intuitively. For example, we can use indicator lights 135 to know whether the barcode reading was successful. There can be two indicator lights 135, located on the left and right sides of the first through hole 1311, respectively. One indicator light 135 emits green light to indicate successful barcode reading, and the other indicator light 135 emits red light to indicate barcode reading failure.

[0058] The third lens 147 can be a collimating lens, which can convert the light emitted by the indicator light 135 into collimated light.

[0059] It should be noted that the first lens 142, the second lens 145, and the third lens 147 can also be selected as lenses with specific angles as needed, so that the angle of the light beam can be locked, for example, it can be 8°, 15°, 25°, 45°, 60°, 90°, 120°, etc. The first lens 142, the second lens 145, and the third lens 147 can also be selected as lenses with specific directions as needed, so that they scatter according to a predetermined angle and shape.

[0060] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of protection of this application.
