Description

Technical Field

[0001] This utility model relates to the technical field of light sources for machine vision inspection, and more particularly to a waterproof light source structure. Background Technology

[0002] In the field of machine vision inspection, some current light source structures need to be positioned below the object being inspected. Taking an egg as an example, when visually inspecting an egg, the light source structure is positioned below the egg and illuminates it upwards, while the camera is positioned above the egg and captures images downwards. In this case, the light source structure acts as a backlight for the egg, with the light emitted passing through the egg before entering the camera. This setup can be used to inspect the internal condition of the egg and determine if it is damaged. However, with this setup, during the conveyor belt process, egg liquid may drip onto the light source structure, or cleaning liquid may splash onto the surface of the light source structure during the cleaning process. Therefore, for applications where the light source structure is located below the object being inspected, a waterproof design is required for the light source structure. Utility Model Content

[0003] This invention provides a waterproof light source structure, which mainly solves the technical problem of how to achieve waterproofing when the light source structure is used as a backlight.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A waterproof light source structure is disclosed for use in visual inspection and for placement below an object being inspected. The light source structure includes a base, a light-emitting component, and a waterproof cover. The light-emitting component is fixed to the base. The waterproof cover covers the periphery of the light-emitting component to enclose it and is sealed to the base. A light-transmitting portion is provided at the top of the waterproof cover away from the base. The light-transmitting portion is located on the light-emitting path of the light-emitting component, and a chamfered structure is provided around the periphery of the light-transmitting portion.

[0006] In one of the technical solutions, the inner wall of the waterproof cover and the outer wall of the base together hold a sealing ring.

[0007] In one of the technical solutions, the outer wall of the base is provided with an annular sealing groove, and the sealing ring is installed in the sealing groove.

[0008] In one of the technical solutions, the base has a threaded hole on the side of the sealing groove facing away from the light-emitting component, and the outer wall of the waterproof cover has a mounting hole at the position corresponding to the threaded hole.

[0009] In one of the technical solutions, the waterproof cover is entirely transparent.

[0010] In one of the technical solutions, the light-emitting component includes a light-emitting shell, a lamp board, a first lens, a second lens, and a diffuser plate;

[0011] The light-emitting shell is fixedly connected to the base and together with the base forms a mounting cavity. The lamp plate, the first lens, and the second lens are all located in the mounting cavity. The lamp plate is fixed to the top of the base. The first lens and the second lens are arranged sequentially along the light-emitting path of the lamp plate. The light-emitting shell has a light-emitting port near the second lens. The diffuser plate is located at the light-emitting port. The light-transmitting part is located on the side of the diffuser plate facing away from the second lens.

[0012] In one of the technical solutions, the light-emitting component further includes an elastic element. The light-emitting shell is provided with a limiting part around the light-emitting port. The diffuser plate is located between the limiting part and the second lens. The elastic element is clamped by the bottom of the first lens and the top of the base. The first lens is pushed upward by the elastic force of the elastic element and abuts against the bottom of the second lens.

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] Please refer to the following: Figure 1 , Figure 2 and Figure 4This utility model embodiment provides a waterproof light source structure for use in the field of visual inspection. The light source structure is positioned below the object being inspected. This light source structure mainly includes a base 1, a light-emitting component 2, and a waterproof cover 3. The light-emitting component 2 is fixed to the base 1, and the waterproof cover 3 covers the periphery of the light-emitting component 2 from top to bottom. The waterproof cover 3 and the base 1 are sealed together. A light-transmitting portion 31 is provided at the top of the waterproof cover 3 away from the base 1. Preferably, the waterproof cover 3 is designed as a completely transparent structure, thus providing the aforementioned light-transmitting portion 31 at its top. In other embodiments, the light-transmitting portion 31 can also be a separate transparent sheet. In fact, this light-transmitting portion 31 is located on the upward light-emitting path of the light-emitting component 2, allowing the light emitted by the light-emitting component 2 to pass through the light-transmitting portion 31 and illuminate the object being inspected. Furthermore, the top of the waterproof cover 3 is provided with a chamfered structure 32 surrounding the outer ring of the light-transmitting portion 31. Figure 5 As shown, when using the light source structure of this solution, the light source structure needs to be placed below the object being detected 10, and a camera 20 can be arranged above the object being detected 10, so that the light source structure of this solution serves as the backlight of the object being detected 10.

[0035] Specifically, this solution uses a waterproof cover 3 to cover the light-emitting component 2, preventing liquid from dripping down onto it. Furthermore, the waterproof cover 3 is sealed to the base 1, preventing liquid from seeping into the light-emitting component 2 through the gap between the waterproof cover 3 and the base 1, thus ensuring the light source structure has excellent waterproof performance. Moreover, to avoid affecting the upward light emission of the light-emitting component 2, this solution sets the top of the waterproof cover 3 as a light-transmitting part 31. In addition, this solution also provides a chamfered structure 32 around the top of the waterproof cover 3, allowing liquid falling from above to slide down along the chamfered structure 32 without accumulating on the top of the waterproof cover 3, thereby ensuring the light source structure can reliably illuminate the object 10 being detected above.

[0036] Please refer to the following: Figure 2 and Figure 4The inner wall of the waterproof cover 3 and the outer wall of the base 1 together hold the sealing ring 4, thereby achieving a sealed connection between the waterproof cover 3 and the base 1. Furthermore, since the sealing ring 4 is hidden inside the waterproof cover 3, it helps improve the appearance of the light source structure. Preferably, an annular sealing groove 11 is provided on the outer wall of the base 1, and the sealing ring 4 is installed in this sealing groove 11 to prevent the sealing ring 4 from shifting during the top-down assembly of the waterproof cover 3, ensuring that the sealing ring 4 is sealed in the designated position. More preferably, the base 1 has multiple threaded holes 12 on the side of the sealing groove 11 facing away from the light-emitting component 2. The multiple threaded holes 12 are arranged circumferentially. The outer wall of the waterproof cover 3 has mounting holes 33 at the corresponding positions of each threaded hole 12. By passing screws through the mounting holes 33 and screwing them into the threaded holes 12, the waterproof cover 3 and the base 1 can be firmly fixed together.

[0037] Please refer to the following: Figures 2 to 4 The light-emitting component 2 specifically includes a light-emitting shell 21, a lamp panel 22, a first lens 23, a second lens 24, and a diffuser plate 25. The light-emitting shell 21 is fitted onto the top of the base 1 and laterally locked to the outer wall of the base 1. The light-emitting shell 21 and the base 1 together form a mounting cavity 26, within which the lamp panel 22, the first lens 23, and the second lens 24 are housed. The lamp panel 22 is fixed to the top of the base 1. The first lens 23 and the second lens 24 are sequentially arranged from bottom to top along the light-emitting path of the lamp panel 22. The light-emitting shell 21 has a light-emitting port 211 corresponding to the position of the second lens 24. The diffuser plate 25 is located at the light-emitting port 211. The aforementioned light-transmitting portion 31 can be understood as being located on the side of the diffuser plate 25 facing away from the second lens 24. When the lamp panel 22 emits light, the light emitted by the lamp panel 22 passes sequentially through the first lens 23 and the second lens 24, then focuses, and finally diffuses evenly upwards through the diffuser plate 25.

[0038] Please refer to them again. Figures 2 to 4The light-emitting component 2 also includes an elastic element 27, which is preferably annular. Furthermore, the light-emitting shell 21 has a limiting portion 212 around the light-emitting port 211, which is preferably annular. The aforementioned diffuser plate 25 is preferably disposed between this limiting portion 212 and the second lens 24. During installation, the diffuser plate 25, the second lens 24, the first lens 23, and the elastic element 27 are sequentially placed into the light-emitting shell 21. Then, the light-emitting shell 21 and the base 1 are interlocked until the elastic element 27 is clamped by the bottom of the first lens 23 and the top of the base 1, so that the elastic element 27 is compressed in the longitudinal direction. At this time, the first lens 23 is pushed upward by the elastic force of the elastic element 27 and abuts against the bottom of the second lens 24. Simultaneously, the second lens 24 is indirectly pushed upward by the elastic force of the elastic element 27, causing the diffuser plate 25 to abut against the bottom surface of the limiting portion 212. It can be seen that by setting the elastic element 27, it is easy to quickly fix the diffuser plate 25, the first lens 23 and the second lens 24, which has the advantage of being easy to assemble and disassemble.

[0039] Please refer to them again. Figures 2 to 4 The base 1 has a recessed mounting groove 13 at its top, and an annular protrusion 14 is formed around the periphery of the mounting groove 13. The lamp plate 22 is fixed to the bottom of the mounting groove 13. The mounting groove 13 can also be used to accommodate part of the first lens 23, thereby helping to reduce the height of the light source structure. The aforementioned elastic member 27 is compressed by the annular protrusion 14 and the first lens 23. In addition, the light source structure of this embodiment also includes a power cord 5. The bottom of the base 1 has an upward-through-the-mount channel 15 that extends into the mounting groove 13. The power cord 5 passes through this channel 15 and is electrically connected to the lamp plate 22. When the power cord 5 is connected to an external power source, it can provide the required power to the lamp plate 22.

[0040] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
