Description

Technical Field

[0001] The utility model relates to the technical field of code reading cameras, and specifically, to a body assembly and a code reading camera including the body assembly. Background Art

[0002] A code reading camera can read the information corresponding to an identification code (for example, it can include barcodes, two-dimensional codes, etc.) on an article by taking pictures of the identification code, so as to quickly identify materials, products or storage containers, and is widely used in various scenarios such as warehousing and transportation, sales, and production workshops.

[0003] A code reading camera generally includes a housing and components such as a photographing module, a lens assembly, and a controller disposed in the housing. Among them, the photographing module is used to take pictures of the identification code on the article through the lens assembly, and the controller (for example, it can be a control circuit board) is used to identify the taken picture to determine the article information corresponding to the identification code. To ensure that the taken picture is clear enough, the lens assembly usually has a lighting function. Specifically, the lens assembly generally includes a lamp group for emitting light and a light homogenizing cover for guiding light and improving the lighting uniformity of the identification code.

[0004] In a code reading camera, the positional accuracy of the lens assembly determines the effect of photographing and code reading. However, existing code reading cameras usually have a relatively complex structure and cumbersome disassembly and assembly steps to meet the requirements of light intensity and waterproof performance. When it is found that the quality inspection standard cannot be met due to problems such as optical path deviation after the product is assembled, it often takes a lot of time to disassemble the overall structure of the product and replace or adjust the position of components such as the light homogenizing cover, seriously affecting the production efficiency of the code reading camera.

[0005] Therefore, how to provide a code reading camera structure with good waterproof performance and convenient maintenance and replacement of structures such as the light homogenizing cover has become an urgent technical problem in this field. Summary of the Utility Model

Detailed implementation manners

[0061] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. Based on the embodiments in the implementation manners, it is intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0062] As used in this specification, the phrase "in one embodiment" or "an example" or "an instance" means that a particular feature, structure, or characteristic described in connection with the embodiment itself can be included in at least one embodiment of the present disclosure. The appearances of the phrase "in one embodiment" in various places in the specification do not necessarily refer to the same embodiment.

[0063] In the existing code reading camera structure, structures such as the light homogenizing cover and other components are usually loaded into the housing through the mounting opening at the top of the housing in sequence with components such as the photographing module, and then the mounting opening is sealed by the cover structure of the housing to achieve the waterproof effect. However, when the product fails the inspection, it is also necessary to first remove the cover structure at the top of the housing, and then remove structures such as the light homogenizing cover from the housing, resulting in a large amount of time spent on disassembling and assembling the code reading camera and maintaining and replacing structures such as the light homogenizing cover after discovering problems with light and photographing during the quality inspection stage, seriously affecting the production efficiency of the code reading camera.

[0064] To solve the above technical problems, as one aspect of the present utility model, a body assembly is provided, and this body assembly is used for a code reading camera, such as Figure 1 、 Figure 5As shown in the figure, the body assembly includes a body housing 100, a light homogenizing cover 210, and at least one cover seal ring 220. The interior of the body housing 100 has a cavity for accommodating the photographing module 620. One side of the body housing 100 has a first mounting hole 110 that communicates the cavity with the outside of the body housing 100. The first end of the light homogenizing cover 210 (i.e., Figure 1 the smaller-sized end on the right side in Figure 1 the figure) is located in the cavity. The second end of the light homogenizing cover 210 (i.e., Figure 1 the larger-sized end on the left side in Figure 1 the figure) corresponds to the position of the first mounting hole 110. The cover seal ring 220 is sleeved on the light homogenizing cover 210, and the cover seal ring 220 seals and connects the light homogenizing cover 210 to the inner wall of the first mounting hole 110.

[0065] In the body assembly provided by the present utility model, the cover seal ring 220 can seal the gap between the light homogenizing cover 210 and the inner wall of the first mounting hole 110, and can also stabilize the position of the light homogenizing cover 210 through the pressure and frictional force between the cover seal ring 220 and the inner wall of the first mounting hole 110. Moreover, the light homogenizing cover 210 can be taken out from the inside of the body housing 100 through the first mounting hole 110. Thus, while ensuring the sealing performance of the body assembly by using the cover seal ring 220, when problems occur with the light homogenizing cover 210 and related light-emitting and light-guiding components and need to be maintained or replaced, the light homogenizing cover 210 can be directly taken out from one side of the first mounting hole 110 for maintenance operations, improving the efficiency of maintaining and replacing the light homogenizing cover 210 and related structures, and thereby ensuring the production efficiency of the code reading camera.

[0066] After testing, the code reading camera adopting the body assembly structure provided by the present utility model can meet the requirements of IP67 and can effectively prevent liquid from entering the inside of the code reading camera.

[0067] It can be understood that the body assembly provided by the present utility model can be used to form a code reading camera product with other components. For example, the body assembly can be connected to a handle structure to form a handheld code reading camera, and the user can hold the handle structure and lift the code reading camera for code reading operations; or it can also be connected to a fixed base structure to form a desktop code reading camera. The desktop code reading camera is placed on the workbench through the fixed base structure, and the user can align an item with an identification code (such as a barcode, a QR code) with the code reading camera for code reading operations.

[0068] As an optional implementation manner of the present utility model, as shown in Figure 1 、 Figure 6 the figure, the light homogenizing cover 210 includes a light guiding conical tube 211 and a light transmitting sheet 212. The size of the light guiding conical tube 211 gradually increases in the direction from the first end of the light homogenizing cover 210 to the second end of the light homogenizing cover 210. The light transmitting sheet 212 seals the opening on the side of the light guiding conical tube 211 facing the first end of the light homogenizing cover 210.

[0069] It can be understood that the light guide cone 211 and the light-transmitting sheet 212 are made of different materials. The light guide cone 211 is made of a semi-translucent material, and light is scattered in the light guide cone 211 to ensure the uniformity of the illumination of the identification code. The light-transmitting sheet 212 needs to be made of a transparent material, and the photographing module 620 takes pictures of external objects through the light-transmitting sheet 212.

[0070] As an alternative embodiment of the present invention, the material of the light-transmitting sheet 212 is glass.

[0071] As an alternative embodiment of the present invention, the light guide cone 211 and the light-transmitting sheet 212 are adhesively connected.

[0072] To further improve the accuracy and stability of the light-emitting angle of the light homogenizing cover 210, as a preferred embodiment of the present invention, as Figure 1 、 Figure 2 shown, a fitting table 213 extending around the outer wall of the light guide cone 211 is formed on the light guide cone 211. The cover body sealing ring 220 is arranged on the fitting table 213. There is a step surface a1 on the connection position between the first mounting hole 110 and the inner cavity facing the outside of the fuselage shell 100. One side of the fitting table 213 is adhesively connected to the step surface a1.

[0073] In the embodiment of the present invention, the cross-sectional dimension of the first mounting hole 110 is larger than the dimension of the inner cavity at the connection position, so as to form an outward step surface a1 at the connection position. The fitting table 213 of the light homogenizing cover 210 is positioned through the step surface a1, so as to ensure the accuracy of the light-emitting angle of the light homogenizing cover 210. Moreover, the side surface of the fitting table 213 is adhesively connected to the step surface a1, so that when the code reading camera shakes or collides during use, the position stability of the light homogenizing cover 210 and related components can be ensured.

[0074] To ensure the sealing effect, as a preferred embodiment of the present invention, as Figure 1 、 Figure 2 shown, a first sealing groove is formed in the fitting table 213, and the cover body sealing ring 220 is arranged in the first sealing groove.

[0075] In the embodiment of the present invention, the outer side of the fitting table 213 (i.e., the side facing away from the axis of the light guide cone 211) has a first sealing groove, and the cover body sealing ring 220 is accommodated in the first sealing groove. Thus, during the process of pressing the light homogenizing cover 210 into the first mounting hole 110, the two side walls of the first sealing groove can limit the lateral deformation amount of the cover body sealing ring 220, ensure the pressure between the cover body sealing ring 220 and the side wall of the first mounting hole 110, and further ensure the sealing effect of the cover body sealing ring 220 on the first mounting hole 110, improving the waterproof performance of the fuselage assembly.

[0076] As an alternative embodiment of the present invention, asFigure 1 , Figure 2 As shown in Figure 2 , there is at least one weight-reducing groove 215 on the outer surface of the mating table 213 to reduce the overall size of the code scanning camera.

[0077] To further ensure the sealing effect, as a preferred embodiment of the present invention, as Figure 1 , Figure 2 shown, there is at least one sealing rib 221 extending along the outer wall of the light homogenizing cover 210 on the surface of the cover body sealing ring 220 facing away from the light homogenizing cover 210.

[0078] In the embodiment of the present invention, there is at least one sealing rib 221 on the outside of the cover body sealing ring 220, so as to further increase the contact pressure between the cover body sealing ring 220 and the inner wall of the first mounting hole 110 by reducing the actual contact area between the cover body sealing ring 220 and the inner wall of the first mounting hole 110, and ensure the sealing effect.

[0079] Preferably, there are multiple sealing ribs 221 on the cover body sealing ring 220, so that even if part of the liquid passes through the first sealing rib 221 under high-intensity impact, the sealing rib 221 can cut it off from the external liquid, thereby further improving the sealing effect by using multiple sealing ribs 221.

[0080] As an alternative embodiment of the present invention, as Figure 1 , Figure 2 shown, there are two sealing ribs 221 on the cover body sealing ring 220.

[0081] As an alternative embodiment of the present invention, as Figure 1 , Figure 6 shown, the shape of the first mounting hole 110 corresponds to the shape of the outer wall of the second end of the light homogenizing cover 210, and there is a preset fitting gap between the outer wall of the second end of the light homogenizing cover 210 and the inner wall of the first mounting hole 110.

[0082] As an alternative embodiment of the present invention, as Figure 1 , Figure 6 shown, the cross-sectional shape of the inner wall of the light homogenizing cover 210 is a rounded rectangle, that is, the light homogenizing cover 210 is an approximate quadrangular pyramid structure, and correspondingly, the shape of the first mounting hole 110 is also approximately a rounded rectangle.

[0083] To further improve the stability of the position of the light homogenizing cover 210, as a preferred embodiment of the present invention, as Figure 5 shown, the first end of the light homogenizing cover 210 has a plurality of inner mounting portions 214 extending in a direction away from the second end of the light homogenizing cover 210, and the inner mounting portions 214 are detachably and fixedly connected to the body housing 100.

[0084] In an embodiment of the present utility model, the first end of the light homogenizing cover 210 has an inner mounting portion 214 extending into the interior of the fuselage housing 100, and the inner mounting portion 214 can be detachably and fixedly connected to the fuselage housing 100, thereby further improving the position stability of the light homogenizing cover 210 during use, and further ensuring the stability of the overall structure of the fuselage assembly.

[0085] As an alternative embodiment of the present utility model, as Figure 5 shown, the inner mounting portion 214 has a cover body mounting through hole, and the inner mounting portion 214 is fixedly connected to the fuselage housing 100 by a fastener 340 (such as a screw) passing through the cover body mounting through hole.

[0086] It can be understood that when it is necessary to remove the light homogenizing cover 210, first remove the fastener 340 for fixing the light homogenizing cover 210 (specifically, insert a tool through the assembly opening 160 to remove the fastener 340), and then pull out the light homogenizing cover 210 from the first mounting hole 110. When reinstalling the light homogenizing cover 210 or replacing the light homogenizing cover 210 after maintenance, first snap the light homogenizing cover 210 into the fuselage housing 100 through the first mounting hole 110, and then reinstall the fastener 340 for fixing the light homogenizing cover 210.

[0087] As a preferred embodiment of the present utility model, as Figure 1 shown, the fuselage housing 100 includes an inner housing 101 and an outer housing 102. The outer housing 102 is disposed on the outside of the inner housing 101, and the outer housing 102 has an indication avoidance opening 120. The inner housing 101 is exposed at the indication avoidance opening 120 to form an indication portion, and an indicator light (not shown in the figure) is disposed in the inner cavity. The indicator light is used to irradiate the indication portion from the inside to make the indication portion emit light.

[0088] It can be understood that the material of the inner housing 101 is different from that of the outer housing 102. The inner housing 101 has a certain light transmissivity, and the inner housing 101 is exposed at the indication avoidance opening 120 of the outer housing 102. Thus, the light emitted by the indicator light can be observed through the material of the inner housing 101 at the indication avoidance opening 120, realizing the internal placement of the indication light source. While realizing information prompting through the indicator light (for example, emitting a red light prompt when the recognition fails and emitting a green light when the recognition is successful), the integrity of the fuselage housing 100 is ensured, and the waterproof effect of the fuselage assembly is further improved.

[0089] Preferably, the elasticity of the inner housing 101 is better than that of the outer housing 102. Thus, when there is a bump or shake, the inner housing 101 can buffer the displacement of the internal components of the fuselage assembly, further ensuring the stability of the fuselage assembly.

[0090] As an alternative embodiment of the present utility model, the inner housing 101 is made of thermoplastic polyurethane elastomer rubber (TPU).

[0091] Optionally, the inner housing 101 and the outer housing 102 are integrally formed by an injection molding process.

[0092] To further improve the waterproof performance of the fuselage housing 100, as a preferred embodiment of the present utility model, as Figure 1 、 Figure 3 shown, the fuselage assembly further includes a pendant 310 and an indicator circuit board 320. The fuselage housing 100 has an indicator mounting hole 130 penetrating along the thickness direction of the fuselage housing 100. The indicator circuit board 320 is disposed in the inner cavity, and the pendant 310 is disposed outside the housing. The pendant 310 and the indicator circuit board 320 are connected to each other by a fastener 340 passing through the indicator mounting hole 130. The indicator circuit board 320 is connected to the indicator light and is used to drive the indicator light to emit light. As Figure 7 shown, the pendant 310 has a rope-passing structure 312 for fixing a knot.

[0093] In the embodiment of the present utility model, the pendant 310 for lifting the fuselage assembly by threading and the indicator circuit board 320 for supplying power to the indicator light and controlling the indicator light to emit light are respectively disposed on the inner and outer sides of the housing. The two are connected to each other by a fastener 340 passing through the indicator mounting hole 130, so that the same fastener 340 is used to connect the two components inside and outside, and the fastener 340 can be installed from the inside of the fuselage assembly, without exposing the fastener 340 outside the pendant 310, reducing the possible water-permeable gaps outside the fuselage assembly, and further improving the waterproof performance of the fuselage housing 100 while simplifying the structure of the fuselage assembly.

[0094] As an alternative embodiment of the present utility model, as Figure 1 、 Figure 3 shown, the fuselage assembly further includes an elastic gasket 330, and the elastic gasket 330 is disposed between the indicator circuit board 320 and the inner wall of the fuselage housing 100.

[0095] As an alternative embodiment of the present utility model, the elastic gasket 330 is made of silica gel.
