Description

Technical Field

[0001] This utility model relates to the field of machine vision technology, specifically to a barcode reader camera. Background Technology

[0002] In industrial production, barcode readers are frequently used, and they can be applied in scenarios with different humidity and temperature conditions as needed.

[0003] During operation, the camera's window is in direct contact with the external environment (the window temperature is basically the same as the external environment temperature during use). However, the internal temperature of the camera is relatively high during operation, and in some usage scenarios, water vapor may appear inside the window, affecting the camera's performance. Utility Model Content

[0004] This invention aims to address one of the technical problems in related technologies to a certain extent. To this end, this invention provides a barcode reader camera that is easy to install and can prevent fogging inside the viewing window.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a barcode reader camera, comprising a camera housing, a viewing window cover, a lens mount, and multiple electrical modules. The viewing window cover is disposed at the front end of the camera housing, and the lens mount and multiple electrical modules are disposed within the inner cavity of the camera housing. The lens mount is opposite to and spaced apart from the viewing window cover. A lens cavity is formed within the camera housing between the lens mount and the viewing window cover. The barcode reader camera further comprises a sealing assembly disposed within the gap between the viewing window cover and the lens mount. The sealing assembly surrounds the lens cavity and seals the gap between the viewing window cover and the lens mount, thereby sealing and isolating the lens cavity and the camera housing in cavities outside the lens cavity. The electrical components of the electrical modules are disposed in the inner cavity of the camera housing outside the lens cavity.

[0006] In this technical solution, a sealing component is provided in the gap between the window cover and the lens mount, which can form a sealed lens cavity to accommodate the lens assembly. During operation, the sealing component of the lens cavity prevents moisture from entering the camera and avoids fogging inside the window.

[0007] Furthermore, at least one of the electrical modules is disposed within the gap between the lens mount and the window cover plate, and the sealing assembly includes a plurality of sealing isolation rings. Along the spacing direction of the lens mount and the window cover plate, sealing isolation rings are respectively disposed within the gaps between the at least one electrical module and the window cover plate and the lens mount.

[0008] Furthermore, the at least one electrical module includes a mounting plate and electrical components disposed on the mounting plate. The mounting plate is fixed inside the camera housing and faces the viewfinder cover. The mounting plate has a through-hole communicating with the lens cavity. A sealing isolation ring is disposed around the through-hole, and the electrical components are located outside the sealing isolation ring. By isolating the electrical components from the outside through the sealing isolation ring, the heat generated by the electrical components during operation can be prevented from entering the lens cavity. This effectively prevents fogging inside the lens viewfinder, as two necessary conditions that are difficult to form inside the lens cavity are a certain amount of humidity and a certain temperature difference.

[0009] Furthermore, the plurality of electrical modules include a fill light board module, an interface board module, and a sensor module. The interface board module is electrically connected to the fill light board module and the sensor module, respectively. A portion of the fill light board module and the interface board module are disposed on the front side of the lens mount and located in the gap between the lens mount and the viewing window cover. The sensor module is disposed on the rear side of the lens mount. The barcode reader also includes a light-transmitting bracket. Along the spacing direction between the lens mount and the viewing window cover, the viewing window cover, the light-transmitting bracket, the fill light board module, the interface board module, and the lens mount are sequentially and spaced apart. The sealing isolation rings are respectively disposed in the gaps between adjacent components.

[0010] Furthermore, the camera housing includes a front shell and a rear shell, which are detachably snapped together and sealed together. The window cover is disposed at the front end of the front shell, the fill light board module and the light-transmitting bracket are disposed inside the front shell, and the lens mount, the interface board module and the sensor module form independent functional modules and are detachably disposed inside the rear shell.

[0011] Furthermore, the sensor module includes multiple connecting parts, which are used to be fixedly connected to the rear shell via connectors. The multiple connecting parts are separately arranged on opposite sides of the sensor module, and at least one connecting part is fixedly connected to the rear shell via connectors extending from the outside of the rear shell.

[0012] Furthermore, the plurality of connecting parts include connecting holes and connecting posts, which are respectively disposed on opposite sides of the sensor module. The connecting holes are used to connect to the inner wall of the rear shell through connecting parts, and the connecting posts are connected to the rear shell through connecting parts that pass through the outside of the rear shell, forming a seal with the connecting parts corresponding to the connecting posts and the rear shell.

[0013] Furthermore, the interface board module includes a first rigid board unit and a second rigid board unit. The first rigid board unit is electrically connected to the fill light board unit. The first rigid board unit is located on the front side of the lens mount, and the second rigid board unit is located on the side of the lens mount and fixedly connected to the lens mount, and is located between the fill light board module and the lens mount. The first rigid board unit and the second rigid board unit are electrically connected through a flexible circuit board, so that the first rigid board unit can be folded relative to the lens mount. The second rigid board unit and the sensor module are electrically connected through a flexible circuit board.

[0014] Furthermore, the barcode reader also includes an external plug, which is detachably disposed on the rear housing. The external plug includes a plug body and a flexible cable. The plug body is fixedly and sealed to the rear housing. The flexible cable is disposed inside the rear housing and electrically connected to the first rigid board unit. The length of the flexible cable is greater than the distance between the connection point of the first rigid board unit and the flexible cable and the plug body in the assembled state.

[0015] Furthermore, the sealing component is made of at least one of silicone and foam.

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0027] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0028] During operation, the electronic components inside the barcode reader camera generate heat. The necessary conditions for water vapor to form are a certain amount of humidity and a certain temperature difference. When the high-temperature humidity inside the camera comes into contact with the viewing window, it can easily cause fogging on the inner wall of the viewing window.

[0029] One embodiment of this utility model discloses a barcode reader camera, see attached document. Figures 1 to 6 The barcode reader camera includes a camera housing 10, a window cover 111, a lens mount 121, and multiple electrical modules. The window cover 111 is located at the front end of the camera housing 10. In actual installation, the window cover 111 is generally connected to the camera housing 10 by dispensing adhesive. The dispensing adhesive connection not only achieves the desired effect but also seals the connection between the window cover 111 and the camera housing 10. It also facilitates the replacement of the window cover 111 as needed.

[0030] The lens mount 121 and multiple electrical modules are disposed within the inner cavity of the camera housing. The lens mount 121 is opposite to and spaced apart from the window cover plate 111. A lens cavity 13 is formed within the camera housing 10, located between the lens mount 121 and the window cover plate 111. The barcode reader camera also includes a sealing assembly 20, which is disposed within the gap between the window cover plate 111 and the lens mount 121. The sealing assembly 20 surrounds the lens cavity 13 and seals the gap between the window cover plate 111 and the lens mount 121, thereby sealing and isolating the lens cavity 13 and the camera housing 10 outside the lens cavity 13. The electrical components of the electrical modules are disposed within the inner cavity of the camera housing 10 outside the lens cavity 13.

[0031] The barcode reader camera also includes a lens assembly. During installation, one end of the lens assembly 122 is sealed and connected to the lens mount 121, and the other end of the lens assembly 122 is disposed inside the lens cavity 13. The barcode reader camera also includes a sealing assembly 20, which is disposed in the gap between the window cover plate 111 and the lens mount 121. The sealing assembly 20 surrounds the lens cavity 13 and seals the gap between the window cover plate 111 and the lens mount 121, so that the lens cavity 13 and the camera housing 10 are sealed and isolated in the cavity outside the lens cavity 13.

[0032] In this embodiment, there is no object obstructing the view between the front end of the lens assembly 122 and the view cover 111.

[0033] In this embodiment, the sealing component 20 is disposed within the gap between the window cover plate 111 and the lens mount 121. The sealing component 20 surrounds the lens cavity 13 and seals the gap between the window cover plate 111 and the lens mount 121. Combined with the sealing connection structure between the lens assembly 122 and the lens mount 121, the lens cavity 13 forms an independent sealed space. During operation, the sealing component 20 of the lens cavity 13 prevents moisture from entering the camera, thus avoiding fogging inside the window.

[0034] This embodiment does not specifically limit the installation method of the sealing component 20. In actual installation, the sealing component 20 is generally set as a ring. The two ends of the sealing component 20 can respectively abut against the front end face of the window cover plate 111 and the lens mount 121. Of course, in some embodiments, there may be other components between the window cover plate 111 and the lens mount 121. In this case, the sealing component 20 may include multiple sealing isolation rings. Each pair of adjacent components is provided with a sealing isolation ring to specifically seal the gap between the components.

[0035] In this embodiment, the material of the sealing component 20 is not specifically limited. In actual installation, the sealing component 20 can be made of different materials depending on the installation location. Specifically, it can be made of silicone or foam, etc.

[0036] In this embodiment, the sealing component 20 can also isolate the electrical components in the electrical module inside the camera housing 10 from the lens cavity 13. During operation, the electronic components, being the working parts, generate heat. By physically isolating the electronic components from the lens cavity 13, the heat generated by the electrical components can be prevented from entering the lens cavity 13. It can be seen that the sealing component 20 in this embodiment can, on the one hand, prevent moisture inside the camera housing 10 from entering the lens cavity 13, and on the other hand, isolate the heat generated by the electronic components from entering the lens cavity 13. This effectively prevents fogging inside the lens window, as the two necessary conditions that are difficult to form inside the lens cavity 13—a certain level of humidity and a certain temperature difference—are thus present.

[0037] As one embodiment of this utility model, see the appendix. Figure 1 The barcode reader camera also includes multiple electrical modules, at least one of which is disposed in the gap between the lens mount 121 and the window cover plate 111. The sealing assembly 20 includes multiple sealing isolation rings, and the sealing isolation rings are respectively disposed in the gap between the at least one electrical module and the window cover plate 111 and the lens mount 121 along the spacing direction of the lens mount 121 and the window cover plate 111.

[0038] In this embodiment, an electrical module is provided between the lens mount 121 and the window cover plate 111. When the sealing assembly 20 is installed, in order to ensure the sealing effect of the lens cavity 13, sealing isolation rings are respectively provided in the gap between the electrical module and the window cover plate 111.

[0039] As one embodiment of the present invention, the at least one electrical module includes a mounting plate and electrical components disposed on the mounting plate. The mounting plate is fixed inside the camera housing 10 and is opposite to the window cover plate 111. The mounting plate is provided with a through opening that communicates with the lens cavity 13. The sealing isolation ring is disposed around the through opening, and the electrical components are located outside the sealing isolation ring.

[0040] The electrical module in this embodiment includes a mounting plate and electronic components. The electronic components are integrated on the mounting plate, which serves as the mounting base. It is typically fixed inside the camera housing 10 using connectors 31 (screws and bolts, etc.). In this embodiment, the mounting plate provides the mounting base for the sealing isolation ring. The electrical components are located on the outside of the sealing isolation ring, while the lens cavity 13 is located on the inside. The electrical components and the lens cavity 13 are isolated from each other by the sealing isolation ring. Different electrical modules in this embodiment have different electrical components. For example, the fill light board module 112 includes a mounting plate and a fill light assembly (electrical components); the interface board module 123 includes a mounting plate and a aiming light assembly (electrical components), etc.

[0041] As one embodiment of this utility model, see the appendix. Figures 1 to 3 The plurality of electrical modules include a fill light board module 112, an interface board module 123, and a sensor module 124. The interface board module 123 is electrically connected to the fill light board module 112 and the sensor module 124 respectively. A portion of the fill light board module 112 and the interface board module 123 are disposed on the front side of the lens mount 121 and located in the gap between the lens mount 121 and the window cover plate 111. The sensor module is disposed on the rear side of the lens mount 121. The barcode reader also includes a light-transmitting bracket 113. Along the spacing direction between the lens mount 121 and the window cover plate 111, the window cover plate 111, the light-transmitting bracket 113, the fill light board module 112, the interface board module 123, and the lens mount 121 are arranged sequentially with gaps. The sealing isolation rings are respectively disposed in the gaps between adjacent components.

[0042] In this embodiment, the fill light board module 112, part of the interface board module 123, and the light-transmitting bracket 113 are all arranged in the gap between the lens mount 121 and the window cover plate 111. That is, multiple components are arranged in the gap between the lens mount 121 and the window cover plate 111. In order to ensure the sealing effect of the lens cavity 13, a sealing isolation ring is also provided in the gap between each component.

[0043] As one embodiment of this utility model, see the appendix. Figure 1 The camera housing 10 includes a front housing 11 and a rear housing 12, which are detachably fastened and sealed together. Figure 1 As shown, a second sealing ring 33 is provided at the connection between the front shell 11 and the rear shell 12. The window cover plate 111 is provided at the front end of the front shell 11. The fill light plate module 112 and the light-transmitting bracket 113 are provided inside the front shell 11. The lens mount 121, the interface board module 123 and the sensor module 124 form independent functional modules and are detachably provided inside the rear shell 12.

[0044] In this embodiment, the camera housing 10 is divided into two parts, namely the front housing 11 and the rear housing 12. In the specific design, in order to facilitate modular assembly, the various components of the barcode reader camera can be separately arranged in the front housing 11 and the rear housing 12.

[0045] Specifically, the viewing window cover 111 and the supplementary light panel module 112 can be housed within the front housing 11. In actual use, the viewing window cover 111 can be a fully transparent cover, a semi-polarized cover, or a fully polarized cover; it can be replaced as an accessory as needed. The supplementary light panel in the supplementary light panel module 112 can emit red, blue, white, infrared, or ultraviolet light; it can also be replaced as an accessory as needed. Therefore, by housing both the replaceable viewing window cover 111 and the supplementary light panel module 112 within the front housing 11, forming a modular unit, users can easily replace them in a modular manner, making replacement simple and offering greater choice.

[0046] The following is a detailed description of the assembly process of each component within the front shell 11 assembly:

[0047] First, the window cover 111 and the front shell 11 are assembled together using an adhesive dispensing process; then, the light-shielding silicone 21 (sealing isolation ring) is clamped onto the lens bracket using an interference fit (the light-shielding silicone 21 serves both a light-shielding and sealing effect); then, both are placed into the cavity of the front shell 11 and secured by screw posts; next, the first isolation foam 22 (sealing isolation ring) is pasted onto the central circular hole in the lens bracket; finally, the supplementary light panel assembly is assembled using the positioning posts on the lens bracket and fixed to the screw posts of the front shell 11 using screws, etc., pressing the lens bracket and the light-shielding silicone 21 in the middle for fixation; as follows: Figure 1 , 2 As shown.

[0048] In this embodiment, the lens mount 121, interface board module 123, and sensor module 124 form independent functional modules and are detachably installed inside the rear shell 12. When assembling the various components inside the rear shell 12, the lens mount 121, lens assembly 122, sensor module 124, indicator light board 128 (located on the side of the lens mount 121), interface board module 123, and main board module 125 (located on the bottom side of the lens mount 121) are first assembled into a module (defined as the core module) outside the rear shell 12, and then placed into the rear shell 12 as a whole. Assembly outside the rear shell 12 provides more operating space and makes operation simple and convenient. In actual setup, the main board module 125, sensor module 124, and indicator light board 128 are electrically connected. In order to ensure the overall appearance of the camera, button stickers and button blocks can also be set at the positions corresponding to the indicator light board 128 on the outer wall of the rear shell 12.

[0049] After the core module is assembled, the core module is placed inside the back shell 12 and the module is fixedly connected to the back shell 12. Specifically, the sensor module 124 includes multiple connecting parts, which are used to be fixedly connected to the back shell 12 through connecting members 31. The multiple connecting parts are separately arranged on opposite sides of the sensor module 124, and at least one connecting part is fixedly connected to the back shell 12 through a connecting member 31 that passes through the outside of the back shell 12.

[0050] In this embodiment, the core module and the back cover 12 can be fixedly connected by a connector 31 that passes through the outside of the back cover 12. Compared with the structure that is connected inside the back cover 12, the connection structure of the barcode reader in this embodiment does not need to reserve operating space and installation space for the core module in the cavity of the back cover 12, which can greatly reduce the volume of the back cover 12 and thus make the barcode reader more compact.

[0051] Furthermore, the structure of connecting by externally threaded connector 31 can reduce the work required to operate inside the rear shell 12 cavity during production, making operation and production more convenient and helping to improve production efficiency.

[0052] In this embodiment, the core module is connected to the rear shell 12 via the sensor module 124. In actual settings, in some application scenarios, the connection part can also be set on the motherboard module 125, the lens mount 121, or other components.

[0053] In one embodiment of this utility model, the plurality of connecting parts include connecting holes and connecting posts 1241. The connecting holes and connecting posts 1241 are respectively disposed on opposite sides of the sensor module 124. The connecting holes are used to connect to the inner wall of the rear shell 12 through connecting members 31. The connecting posts 1241 are connected to the rear shell 12 through connecting members 31 that pass through the outside of the rear shell 12. The connecting members 31 corresponding to the connecting posts 1241 and the rear shell 12 form a seal.

[0054] In this embodiment, the connection structure between the core module and the rear shell 12 is partly connected inside the rear shell 12 and partly connected outside the rear shell 12. Since the connector 31 is inserted from outside the rear shell 12 to connect with the core module, a connecting post 1241 needs to be set at the connection point, such as a connecting post 1241 on the mounting plate of the sensor module 124 (which will increase the structural complexity of the electrical module). Through the cooperation of internal and external connections, the structure of the electrical module and the volume of the rear shell 12 can be balanced, and the overall structure is more compact.

[0055] When the connection is made through the externally inserted connector 31, in order to ensure the overall sealing effect of the camera housing 10, a first sealing ring 32 can be set between the connector 31 and the rear housing 12 to ensure the sealing effect of the connection and mating parts. In addition, in order to ensure the overall appearance of the code reader camera, a decorative piece 34 can be covered on the outside of the external connector 31.

[0056] As one embodiment of this utility model, see the appendix. Figure 4 , 5 6. The interface board module 123 includes a first rigid board unit 1231 and a second rigid board unit 1232. The first rigid board unit 1231 is electrically connected to the fill light board unit. The first rigid board unit 1231 is located on the front side of the lens mount 121. The second rigid board unit 1232 is located on the side of the lens mount 121 and is fixedly connected to the lens mount 121. It is located between the fill light board module 112 and the lens mount 121. The first rigid board unit 1231 and the second rigid board unit 1232 are electrically connected through a flexible circuit board 126 so that the first rigid board unit 1231 can be folded relative to the lens mount 121. The second rigid board unit 1232 and the sensor module 124 are electrically connected through the flexible circuit board 126.

[0057] In this embodiment, the interface board module 123 is divided into two parts, wherein the first rigid board unit 1231 and the second rigid board unit 1232 are electrically connected through a flexible circuit board 126. See attached diagram. Figure 4 , 5 The first rigid board unit 1231 is disposed on the front side of the lens mount 121, and a third isolation foam 24 (sealing isolation ring) is disposed between it and the front end face of the lens mount 121. The second rigid board unit 1232 is disposed on the side of the lens mount 121 and is electrically connected to the sensor module 124 located on the rear side of the lens mount 121 through a flexible circuit board 126. In this way, after the sensor module 124 and the interface board module 123 are connected, the design of the flexible circuit board 126 allows the connected structure to be quickly fixed in the corresponding position. Moreover, after one component is fixed, the other components can also be rotated to the installation position under the action of the flexible circuit board 126, making the installation position easier to adjust and improving the convenience of installation.

[0058] Moreover, as mentioned above, the flexible connection allows different components to be placed in different locations. As mentioned above, multiple connected components are respectively placed on the front, rear and periphery of the lens mount 121, so that multiple components can be fixed on the lens mount 121 as a base, which is convenient for installation and helps to reduce the overall size.

[0059] As one embodiment of this utility model, the barcode reader camera further includes an external plug 127, which is detachably disposed on the rear shell 12. The external plug 127 includes a plug body 1271 and a flexible cable 1272. The plug body 1271 is fixedly and sealed to the rear shell 12. The flexible cable 1272 is disposed inside the rear shell 12 and electrically connected to the first rigid board unit 1231. The length of the flexible cable 1272 is greater than the distance between the connection part of the first rigid board unit 1231 and the flexible cable 1272 and the plug body 1271 in the assembled state.

[0060] See appendix Figure 4 In this embodiment, the external plug 127 is located near the rear end of the rear shell 12. The external plug 127 needs to be electrically connected to the interface board module 123 (first rigid board unit 1231), which is located on the front side of the lens mount 121. There is a certain distance between the external plug 127 and the first rigid board unit 1231. Furthermore, the connection between the external plug 127 and the interface board module 123 is generally made after the core module is installed in the rear shell 12. At this time, the lens mount 121 and other components obstruct the connection, making it inconvenient. Moreover, if the state of the first rigid board unit 1231 is not adjustable, and the front face of the first rigid board unit 1231 faces the lens mount 121, there is no operating space within the rear shell 12 to allow the external plug and interface board module 123 to dock. Through the design of the flexible circuit board 126, during installation, as shown in the attached... Figure 6 As shown, in this embodiment, the first rigid plate unit 1231 can be folded at a certain angle relative to the lens mount 121, creating a larger space between the part that mates with the external plug 127 and the lens mount 121. Within this space, the first rigid plate unit 1231 and the flexible cable 1272 can be plugged in and connected. After the connection is completed, bending the flexible cable 1272 will bring the first rigid plate unit 1231 into a normal assembly state. Similarly, during disassembly, the first rigid plate unit 1231 can be folded down and the connection between the two can be disconnected, which can greatly improve the assembly and disassembly efficiency.

[0061] After the components inside the front shell 11 and the rear shell 12 are assembled, the front shell 11 module and the rear shell 12 module are connected as a whole, and a second isolation foam 23 is set between the fill light board module 112 and the interface board module 123. After assembly, referring to the attached figure, multiple sealing components are sequentially set between the front end face of the window cover 111 and the lens mount 121, namely light-shielding silicone 21, first isolation foam 22, second isolation foam 23 and third isolation foam 24. By sealing the gaps between the components, the airtightness of the lens cavity 13 can be better guaranteed, and fogging inside the window cover 111 can be prevented.

[0062] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
