Description

Technical Field

[0001] This utility model relates to the field of fresh egg detection technology, specifically a fresh egg detection device. Background Technology

[0002] Fresh egg testing devices are specialized equipment that uses the principle of light transmission to observe the internal quality of eggs. Their core function is to quickly screen out substandard eggs (such as those with broken yolks, blood spots, or cracks), ensuring egg quality and food safety. They are widely used in egg farms, egg processing plants, and supermarket quality inspection processes. The core logic of the testing light is to utilize the semi-transparent nature of the eggshell, allowing a specific light source to penetrate the shell and clearly reveal internal defects (such as yolk shape, air cell size, and cracks), replacing the traditional experience-based judgment of "candling" and improving testing accuracy and efficiency.

[0003] Utility model patent CN220068575U discloses a multi-hole egg candling device, comprising: a base, an L-shaped frame mounted on the upper end of the base, and a reinforcing frame for reinforcement at the upper end of the L-shaped frame; the upper end of the L-shaped frame is provided with a placement mechanism for placing eggs to be tested and an egg candling mechanism for candling the placed eggs; the multi-hole egg candling device, through technological innovation, replaces the original single-lamp illumination design with a multi-lamp illumination design. Multiple candling lights arranged at intervals at the lower end of the candling box are movable through a displacement mechanism. This utility model can retract and expand the multiple candling lights arranged at the lower end of the egg box, and when expanded, the distance between two adjacent candling lights can be adjusted to adapt to the distance between adjacent eggs.

[0004] However, in the process of using this utility model, the tray does not have a structure that can illuminate the eggs. It only relies on the lamp to illuminate the surface of the eggs, which cannot illuminate the inside of the eggs. Therefore, it is impossible to judge the quality of the eggs based on the condition inside the eggs, which cannot meet the usage requirements. Therefore, a fresh egg detection device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fresh egg testing device that can illuminate the inside of an egg. This solves the problem that existing egg testing institutions only rely on lamps to illuminate the surface of the egg, which cannot illuminate the inside of the egg, thus making it impossible to judge the quality of the egg based on the internal condition and failing to meet the needs of use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fresh egg detection device, comprising a workbench and a support cover fixedly connected to the top of the workbench, the fresh egg detection device further comprising a support lighting mechanism disposed on the top of the workbench for lighting detection of fresh eggs; The supporting lighting mechanism includes a placement platform set on the top of the workbench. The upper surface of the placement platform has a placement groove adapted to fresh eggs. A light-transmitting plate is fixedly connected to the inner wall of the placement groove. An illumination lamp is fixedly connected to the side of the placement platform near the light-transmitting plate.

[0007] Furthermore, a handle is fixedly connected to the front of the placement platform, a guide rail is fixedly connected to the side of the workbench near the placement platform, and a guide seat adapted to the guide rail is fixedly connected to the bottom of the placement platform.

[0008] Furthermore, there are two guide rails and two guide seats, with the two guide rails symmetrically distributed on the left and right sides of the top of the worktable.

[0009] Furthermore, a mounting sleeve is fixedly connected to the top of the support cover, and a movable rod extending into the interior of the support cover is slidably connected to the top of the mounting sleeve. A fixed baffle is fixedly connected to the outside of the movable rod, and a support spring is fixedly connected between the fixed baffle and the mounting sleeve.

[0010] Furthermore, a label head is fixedly connected to the end of the movable rod near the placement platform, and a handheld head is fixedly connected to the end of the movable rod away from the label head.

[0011] Furthermore, the number of mounting sleeves and the number of placement slots are equal, and the mounting sleeves are located directly above the placement slots.

[0012] Furthermore, the support spring is sleeved on the outside of the movable rod, and a lighting strip is fixedly connected to the inner wall of the support cover.

[0013] Furthermore, the bottom of the workbench is rotatably connected to four casters, which are evenly distributed on the bottom of the workbench.

[0014] Compared with the prior art, the present invention provides a fresh egg detection device, which has the following beneficial effects: 1. This fresh egg testing device, by setting up a placement slot with a light-transmitting plate and integrating the illumination lamp inside the placement platform, forms a professional transmission lighting system. During testing, light is evenly transmitted from below the egg, which can clearly show defects such as the size of the air cell, the outline of the yolk, blood streaks, and cracks inside the egg, greatly improving the accuracy and intuitiveness of the test and effectively avoiding errors from visual observation.

[0015] 2. This fresh egg testing device, through its unique movable rod and support spring design, allows the marking head to be raised naturally under the elastic force of the support spring, without interfering with the placement and transportation of eggs. When it is necessary to mark defective products, the operator only needs to press down on the hand-held head to make the marking head accurately contact the problematic egg and mark it. This solves the problem of existing egg testing institutions that only rely on lamps to illuminate the surface of the egg, which cannot illuminate the inside of the egg and therefore cannot judge the quality of the egg based on the internal condition, thus failing to meet the usage requirements.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 3 A fresh egg detection device in this embodiment includes a workbench 1 and a support cover 2 fixedly connected to the top of the workbench 1, as well as a support lighting mechanism for illuminating and detecting fresh eggs, which is set on the top of the workbench 1. The support lighting mechanism includes a placement platform 3 set on the top of the workbench 1. A placement groove 4 adapted to the fresh eggs is opened on the upper surface of the placement platform 3. A light-transmitting plate 5 is fixedly connected to the inner wall of the placement groove 4. An illumination lamp 6 is fixedly connected to the side of the placement platform 3 near the light-transmitting plate 5.

[0020] Specifically, a handle 7 is fixedly connected to the front of the placement platform 3, a guide rail 8 is fixedly connected to the side of the workbench 1 near the placement platform 3, and a guide seat that matches the guide rail 8 is fixedly connected to the bottom of the placement platform 3. There are two guide rails 8 and two guide seats, and the two guide rails 8 are symmetrically distributed on the left and right sides of the top of the workbench 1.

[0021] It should be noted that the support cover 2 is preferably made of an opaque material, such as black ABS plastic or metal plate. Its function is to isolate external ambient light interference during the test and form a dark room environment, thereby improving the contrast and clarity of the test. The illumination lamp 6 is preferably an LED cold light source. The light emitted by it is evenly scattered upward through the light-transmitting plate 5 to illuminate the egg placed on it. The cold light source can avoid heat accumulation that affects the quality of the egg.

[0022] It should be noted that the sliding cooperation between the guide rail 8 and the guide seat allows the placement platform 3 to be easily pulled out and pushed in like a drawer. Combined with the handle 7 on the front, operators can quickly place and replace eggs, which significantly improves the continuity and efficiency of the inspection operation. It is particularly suitable for assembly line operation scenarios in farms or egg processing plants.

[0023] Please see Figure 1 and Figure 4 In this embodiment, a mounting sleeve 9 is fixedly connected to the top of the support cover 2, and a movable rod 10 extending into the inside of the support cover 2 is slidably connected to the top of the mounting sleeve 9. A fixed baffle 11 is fixedly connected to the outside of the movable rod 10, and a support spring 12 is fixedly connected between the fixed baffle 11 and the mounting sleeve 9. A label head 13 is fixedly connected to the end of the movable rod 10 near the placement platform 3, and a handheld head 14 is fixedly connected to the end of the movable rod 10 away from the label head 13.

[0024] Specifically, the number of mounting sleeves 9 and the number of placement slots 4 are equal. The mounting sleeves 9 are located directly above the placement slots 4. The support spring 12 is sleeved on the outside of the movable rod 10. A lighting strip is fixedly connected to the inner wall of the support cover 2.

[0025] It should be noted that, under natural conditions, the elastic force of the support spring 12 acts on the fixed baffle 11, keeping the entire movable rod 10 at its upper limit position. The lower end of the indicator head 13 is far away from the egg surface and will not interfere with the placement and observation of the egg. The indicator head 13 can be made of absorbent materials such as sponge or soft felt, and can be pre-soaked in harmless food-grade pigments.

[0026] It should be noted that this one-to-one layout allows the operator to directly press the corresponding handheld head 14 above the egg when they observe a defect in a certain position through the support cover 2, achieving precise marking and avoiding confusion.

[0027] Please see Figure 1 In this embodiment, four movable wheels 15 are rotatably connected to the bottom of the workbench 1. The four movable wheels 15 are evenly distributed on the bottom of the workbench 1, and a brake pad is hinged to one side of each movable wheel 15.

[0028] Specifically, the caster wheel 15 is preferably a swivel wheel with a locking function, making it very easy and convenient to move the equipment between workshops, warehouses or different production lines.

[0029] The working principle of the above embodiments is as follows: Pull the placement platform 3 fully out along the guide rail 8 using handle 7, and place the fresh eggs to be tested one by one into the placement slot 4. After completion, push the placement platform 3 back into the workbench 1, so that the eggs are in the dark chamber environment formed by the support cover 2. Turn on the illumination lamp 6 and the lighting strip inside the support cover 2. The light shines evenly from below the egg through the light-transmitting plate 5, and the size of the air cell inside the egg, the shape of the yolk, and whether there are blood streaks, mold spots or foreign objects are clearly visible. When a defect is observed in an egg, the operator directly presses down on the hand-held head 14 of the corresponding marking mechanism directly above the egg. The movable rod 10 moves downward against the elastic force of the support spring 12, causing the marking head 13 at the end to contact the eggshell surface and leave a color mark.

[0030] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
