Description

Technical Field

[0001] This utility model relates to the field of quality inspection equipment, and in particular to an egg quality testing device. Background Technology

[0002] In the quality inspection of eggs during incubation and for sale, light transmission testing is a common method. Traditional light transmission testing involves manually projecting a light source onto the egg for inspection. This method is highly dependent on manual labor and suffers from inconsistent quality inspection standards and the risk of missed detections. Due to the drawbacks of manual inspection, the application of automated quality inspection equipment using cameras for image acquisition is gradually increasing. For example, patent CN112816485A discloses a method and device for inspecting cracked eggs. This device uses a chain to drive a drum-shaped roller to move the egg to a dark box, where it is inspected by a camera after being projected through a light source.

[0003] Currently, this type of quality inspection equipment has the following problems: When the egg is moved above the light source, in order to improve the accuracy of egg detection, the egg is often rotated by a drum-shaped roller. During the rotation, feces, residue and other adhering substances on the surface of the egg are easy to fall off. After the adhering substances fall onto the light source, the brightness of the light source is reduced. Some adhering substances can also cause light spots on the light source, affecting the detection effect. Moreover, after the adhering substances fall onto the light source and are heated by the light source, they are easy to clump and fix on the surface of the light source, which is not easy to clean.

[0012] Furthermore, the light-emitting component is slidably mounted on the frame of the detection device.

[0013] Furthermore, the detection device also includes a cover, which covers the upper side of the portion of the conveyor located above the light-emitting component, and the cover forms the camera mounting portion; the cover extends downward to the side of the light-emitting component at both ends of the main shaft extension direction, and an inspection door is formed at one end of the cover in the main shaft extension direction, and a through hole is opened at the other end corresponding to the fixing groove, and the fan extends out of the outside of the cover through the through hole.

[0024] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0025] Furthermore, it should be understood in the description of this utility model that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0028] In this utility model, such as Figure 1-5 As shown, an egg quality testing device is provided, including a rotatable conveyor 2 and an egg-carrying roller 1 disposed on the conveyor 2. The testing device has a camera mounting part on the upper side of the egg-carrying roller 1. The egg-carrying roller 1 includes a main shaft 102 and egg-carrying columns 101 spaced apart on the main shaft 102. The middle section of the egg-carrying column 101 is narrowed to form an egg-carrying part 5, and the two sides of the middle section form limiting parts 6. The radial dimension of the egg-carrying column 101 at the limiting part 6 is larger than the radial dimension of the egg-carrying part 5. The testing device also includes a light-emitting component. The top surface of the light-emitting component is provided with a light-emitting part 3 and a slag-guiding hole 4 spaced apart. The light-emitting component also includes a negative pressure component connected to the slag-guiding hole 4, and the negative pressure component provides negative air pressure to the slag-guiding hole 4.

[0029] In use, the detection device of this invention provides negative air pressure to the guide hole 4 through the negative pressure component, creating a continuous airflow on the upper side of the light-emitting component that flows towards the guide hole 4. After the egg-carrying roller 1 moves the egg to the upper side of the light-emitting component, when the egg falls downwards and adhering material falls, the falling material can be guided to the guide hole 4 by the airflow, thereby reducing the probability of the material falling onto the light-emitting part 3 and effectively solving the problems existing in the prior art. Moreover, the airflow generated by this invention can simultaneously create a cooling effect on the light-emitting part 3, further improving the working environment of the light-emitting part 3.

[0030] It should be noted that in the illustrated embodiment, the conveyor 2 is illustrated as a chain, which does not limit the present invention. In optional embodiments, other forms of conveyor 2 may be used, such as conveyor 2 made of belt.

[0031] The improvement of this utility model lies in the structure of the light source part in the detection device. The camera and its installation and fixation, the drive of the conveyor 2, and the specific structure of the egg-carrying roller 1 of the quality detection device are not restricted or improved. Those skilled in the art can flexibly choose feasible implementation methods when implementing them.

[0032] In the illustrated embodiment, the light-emitting part 3 and the slag-guiding hole 4 are arranged such that the vertical projection of the egg-carrying part 5 when it moves to the upper side of the light-emitting component falls on the upper side of the light-emitting part 3, and the vertical projection of the limiting part 6 when it moves to the upper side of the light-emitting component at least partially coincides with the slag-guiding hole 4.

[0033] like Figure 5 As shown, this allows the light-emitting part 3 to irradiate the eggs from the lower side of the egg-carrying part 5 for quality inspection. The residue guide hole 4 is located at the edge of the egg-carrying column 101 (at the limiting part 6), which enables the light-emitting part 3 to irradiate the eggs efficiently. The residue guide hole 4 can also be arranged at the edge of the egg-carrying column 101.

[0034] In the illustrated embodiment, more specifically regarding the structure of this utility model, the light-emitting components are provided in multiple intervals along the traveling direction of the conveyor 2, and the light-emitting components are arranged with slag guide holes 4 and light-emitting parts 3 at intervals along the length direction of the main shaft 102.

[0035] like Figures 3 to 5 As shown, this allows the individual light-emitting components to be arranged in a roughly strip-like shape, which facilitates the adjustment of the position of the light-emitting components to adjust the vertical correspondence between the light-emitting part 3 and the slag guide hole 4 and the egg-carrying column 101.

[0036] In the illustrated embodiment, specifically regarding the structure of this utility model, the light-emitting component includes a fixing groove 7, the light-emitting part 3 and the slag-guiding hole 4 are disposed on the top surface of the fixing groove 7, and the negative pressure component includes a fan 8 disposed at one end of the fixing groove 7. As shown in the figure, negative pressure can be provided to the slag-guiding hole through the fan 8. Installing the fan 8 at one end of the fixing groove 7 facilitates the installation and maintenance of the fan 8. Figure 2 and Figure 5 As shown, the fan 8 is mounted on the end of the mounting slot 7 by bolts.

[0037] In the illustrated embodiment, more specifically, the fixing groove 7 has a partition plate 9 formed at one end near the fan 8, and the fixing groove 7 forms an air guide cavity 10 on the side of the partition plate 9 facing the fan 8; the light-emitting component also includes a plurality of connecting pipes 11, one end of the connecting pipe 11 passes through the partition plate 9 and connects to the air guide cavity 10, and the other end is connected to the slag guide hole 4.

[0038] like Figure 5 As shown, the fixed groove 7 forms an air guide cavity 10 on the left side of the partition plate 9. The fan 8 is installed on the left side wall of the air guide cavity 10, so that negative air pressure can be provided to the slag guide hole 4 through each connecting pipe 11. The negative pressure generated by the fan 8 is distributed by the position of each connecting pipe 11 in the air guide cavity 10, so that the negative air pressure of each connecting pipe 11 is relatively balanced, and the negative air pressure distribution of each slag guide pipe is more uniform.

[0039] In the embodiment shown in the figure, the connecting pipe 11 is preferably a corrugated pipe or a rubber pipe with a certain rigidity to prevent the connecting pipe 11 from being compressed and deformed by negative pressure.

[0040] In an optional embodiment, the slag guide hole 4 can be directly connected to the fixed groove 7, with the bottom of the slag guide hole 4 directly connected to the fixed groove 7.

[0041] In the illustrated embodiment, to further specify the structure of this utility model, the light-emitting component includes a slag-guiding funnel 12, which forms the slag-guiding hole 4, and the slag-guiding funnel 12 is detachably installed in the fixing groove 7; the light-emitting part 3 is detachably installed in the fixing groove 7.

[0042] As shown in the figure, by detachably installing the light-emitting part 3 in the fixed groove 7, the light-emitting part 3 can be easily replaced. By detachably setting the slag-guiding funnel 12 in the fixed groove 7, in the embodiment where the connecting pipe 11 is connected to the slag-guiding hole 4, the connecting pipe 11 can be connected to the slag-guiding funnel 12 first, and then the light-emitting part 3 and the slag-guiding funnel 12 can be installed in the fixed groove 7, which facilitates assembly.

[0043] In the illustrated embodiment, for the structure of this utility model, more specifically, the fixing groove 7 is open at the top of the area where the light-emitting part 3 and the slag-guiding funnel 12 are installed to form an installation hole, and the fixing groove 7 is folded inward at the edge of the installation hole to form a flange 13; the slag-guiding funnel 12 and the light-emitting part 3 are respectively engaged with the flange 13.

[0044] like Figure 4 As shown, the upper end of the side edge of the light-emitting part 3 is provided with an upper boss, which overlaps with the flange 13. The portion of the light-emitting part 3 below the upper boss is interference-fitted between the two flanges 13. The clamping structure between the slag-guiding funnel 12 and the flange 13 is the same as the arrangement of the upper boss of the light-emitting part 3. With this arrangement, not only can the assembly and disassembly of the light-emitting part 3 and the slag-guiding funnel 12 be convenient, but the positions of the light-emitting part 3 and the slag-guiding funnel 12 can also be adjusted along the length of the fixing groove 7.

[0045] Regarding the installation method of the light-emitting part 3 and the slag-guiding funnel 12 in the fixing groove 7, in alternative implementations, other methods can also be used, such as fixing the light-emitting part 3 and the slag-guiding funnel 12 to the fixing groove 7 by bolt fixing.

[0046] The method of setting the slag guide hole 4 is not limited to the slag guide funnel 12 shown in the figure. In alternative embodiments, other methods can also be used, such as directly opening a hole in the top of the fixed groove 7 to form the slag guide hole 4.

[0047] In the illustrated embodiment, specifically regarding the mechanism of this invention, the light-emitting component is slidably mounted on the frame of the detection device. For example... Figure 4 As shown, the frame of the detection device is provided with partition ribs, and the fixing groove 7 of the light-emitting component can slide with the partition ribs, so as to facilitate the positioning of the light-emitting component in the traveling direction of the conveyor 2. The positional correspondence between the light-emitting part 3 and the slag guide hole 4 and the egg-carrying column 101 can also be adjusted by moving the light-emitting component.

[0048] In the illustrated embodiment, for the structure of this utility model, more specifically, the detection device further includes a cover 14, which covers the upper side of the upper part of the conveyor 2 located on the light-emitting component, and the cover 14 forms the camera mounting part; the cover 14 extends downward to the side of the light-emitting component at both ends of the extension direction of the main shaft 102, and an inspection door 15 is formed at one end of the extension direction of the main shaft 102, and a through hole 16 is opened at the other end corresponding to the position of the fixing groove 7, and the fan 8 extends out of the outside of the cover 14 through the through hole 16.

[0049] As shown in the figure, the housing 14 can form a light-shielding structure. By providing the inspection door 15, it is convenient to inspect the camera and light-emitting components at the camera mounting position. Furthermore, by extending the fan 8 out of the through hole 16 outside the housing 14, it is convenient to discharge the adhering substances sucked out by the negative pressure of the fan 8. The fan 8 can also be used to extract air from the housing 14 to promote airflow inside and outside the housing 14, thereby further reducing the temperature inside the housing 14 and improving the working environment of the camera and light-emitting components 3.

[0050] In the illustrated embodiment, specifically regarding the structure of this utility model, the fixing groove 7 is provided with a limiting block 17, which abuts against the inner surface of the cover 14 at the through hole 16. This prevents the fixing groove 7 from dislodging outward from the through hole 16.

[0051] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on its differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0052] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
