Description

Technical Field

[0001] This utility model relates to the field of seed quality testing technology, and more specifically to a seed trait genetic information image acquisition terminal. Background Technology

[0002] The automatic seed analysis instrument is an intelligent device integrating multiple advanced technologies. It can be used for image acquisition and analysis of genetic information of seed appearance traits. The device mainly consists of two parts: a backlight device and a tablet with embedded software. The backlight device uses high-brightness LED lights, and the outer frame is made of acrylic material. The software adopts advanced image processing technology and is an embedded software designed based on distance transformation principles, morphology, concave point segmentation, and other technologies. This device is mainly used in the field of agriculture for crop yield measurement and seed evaluation. Through photos taken by the camera, the software automatically calculates the number of seeds, average area, average perimeter, average length, average width, aspect ratio, and other data. Based on the obtained information, it analyzes the genetic information of seed traits and finally outputs the results in the form of lists and graphs for easy viewing and analysis by users.

[0003] A search revealed that utility model patent CN210180384U discloses an automatic seed testing instrument, including a backlight device body. A transparent disk is embedded in the top surface of the backlight device body, and a limiting plate located inside the transparent disk is placed on the top surface of the backlight device body. The limiting plate has a through-type limiting opening. A backlight switch is embedded in one corner of the top surface of the backlight device body. Symmetrically distributed support strips are installed on the bottom surface of the backlight device body, and a movable mounting plate is installed on the support strips. A detachable shooting mechanism is installed at the end of the mounting plate. An adjustment mechanism is provided at the connection between the mounting plate and the support strips.

[0004] In the image acquisition process of existing technologies and this patented device, seeds must be placed on a backlit plate. However, when seeds are poured into the backlit plate, they are difficult to spread out completely, often resulting in overlap and accumulation. This phenomenon can obscure key traits of some seeds (such as shape, color, and texture), making it impossible for the acquired image to fully represent the characteristics of each seed, thus affecting the accuracy of subsequent analysis. For example, in seed morphology analysis, seed overlap can cause deviations in measurements such as length and width. At the same time, uneven seed distribution can lead to differences in the light transmittance of the backlit plate. Some seeds may have uneven brightness in the acquired image due to insufficient or excessive light, reducing image quality and interfering with image-based trait analysis. Furthermore, due to inaccurate image information, subsequent calculations of morphological parameters such as seed area, perimeter, and shape index will produce large errors, making it difficult to accurately reflect the true traits of the seeds and hindering seed quality assessment and genetic analysis. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a seed trait genetic information image acquisition terminal to solve the problems existing in the background art.

[0006] The utility model provides the following technical solution: a seed trait genetic information image acquisition terminal, including a placement platform, an image acquisition device installed on the placement platform, and a flat plate electrically connected to the image acquisition device. A backlight panel is placed on the surface of the placement platform, and grooves are formed on both sides of the backlight panel. Positioning components are installed at both ends inside the backlight panel, and the input end of the positioning component extends into the groove. A motor is fixedly installed inside the placement platform, and a rotating wheel is rotatably connected inside the placement platform. A pulley is fixedly connected to the output end of the motor and the center of the surface of the rotating wheel. A V-belt is installed on the outer surface of the two pulleys. A toothed ring is fixedly connected to the outer surface of the rotating wheel, and a toothed plate is meshed with the surface of the toothed ring. The top of the toothed plate is fixedly connected to the bottom of the backlight panel.

[0007] Furthermore, the positioning component includes equidistant limiting grooves inside the placement platform. A fixed post is fixedly connected inside the limiting groove. A sliding post is slidably connected to the outer surface of the fixed post. Springs are sleeved on both sides of the sliding post on the outer surface of the fixed post. A magnet is fixedly connected to the top of the sliding post. A magnet is magnetically attracted to the top of the magnet. A connecting block is fixedly connected to the top of the magnet. A Z-shaped plate is fixedly connected to the top of the connecting block. A sliding groove is opened inside the placement platform. Limiting rods are fixedly connected longitudinally at equal intervals inside the sliding groove. The Z-shaped plate is slidably connected longitudinally inside the sliding groove through the limiting rods. A toggle plate is fixedly connected to the end of the Z-shaped plate away from the connecting block.

[0008] Furthermore, the toggle plate is longitudinally slidably connected inside the groove, and the opposing surfaces of the second magnet and the first magnet have opposite magnetic properties. The second magnet is longitudinally slidably connected inside the backlight plate.

[0009] Furthermore, the toothed ring is not completely annular, the toothed plate is fixedly embedded in the inner bottom of the backlight plate, and both the rotating wheel and the toothed ring are rotatably connected inside the placement platform.

[0010] Furthermore, a silicone column is fixedly connected to the top of the second magnet. Under normal conditions, the elasticity of the silicone column causes the second magnet to slide closer to the first magnet.

[0011] Furthermore, under normal conditions, the elasticity of the spring keeps the sliding post located at the center of the limiting groove, and the top of the sliding post extends to the upper surface of the placement platform.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model uses a motor to drive a rotating wheel and a toothed ring to rotate, which in turn drives a backlight plate to slide back and forth, achieving horizontal shaking of the backlight plate. This allows the seeds to be evenly distributed on the backlight plate, effectively avoiding the problem of seed overlap and accumulation. It can ensure that the key characteristics such as the shape, color, and texture of each seed are fully presented, reduce measurement deviations caused by occlusion, and significantly improve the integrity of image acquisition and the accuracy of subsequent analysis.

[0014] 2. This utility model, by setting up a positioning component, achieves rapid positioning and fixation of the backlight panel and the placement platform due to the magnetic attraction of magnet one and magnet two. Under normal conditions, the spring force keeps the sliding column in the center, and the magnet attraction ensures the stability of the backlight panel. When replacing, simply push the lever plate in the groove upward to disengage magnet two from magnet one, and the backlight panel can be easily removed, improving the practicality and work efficiency of the equipment.

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0022] A seed trait genetic information image acquisition terminal includes a placement platform 1, an image acquisition device 2 mounted on the placement platform 1, and a flat plate 3 electrically connected to the image acquisition device 2. A backlight plate 4 is placed on the surface of the placement platform 1. Grooves 41 are provided on both sides of the backlight plate 4. Positioning components 11 are installed at both ends inside the backlight plate 4. The input end of the positioning component 11 extends into the groove 41. A motor 5 is fixedly installed inside the placement platform 1. A rotating wheel 6 is rotatably connected inside the placement platform 1. A pulley 7 is fixedly connected to the output end of the motor 5 and the center of the surface of the rotating wheel 6. A V-belt 8 is installed on the outer surface of the two pulleys 7. A toothed ring 9 is fixedly connected to the outer surface of the rotating wheel 6. A toothed plate 10 is meshed with the surface of the toothed ring 9. The top of the toothed plate 10 is fixedly connected to the bottom of the backlight plate 4.

[0023] The positioning component 11 includes limiting grooves 111 equidistantly opened inside the placement platform 1. A fixing post 112 is fixedly connected inside the limiting groove 111. A sliding post 113 is slidably connected to the outer surface of the fixing post 112. Springs 114 are sleeved on both sides of the outer surface of the fixing post 112 located on the sliding post 113. A magnet 115 is fixedly connected to the top of the sliding post 113. A magnet 2 116 is magnetically attracted to the top of the magnet 115. A connecting block 117 is fixedly connected to the top of the magnet 2 116. A Z-shaped plate 119 is fixedly connected to the top of the connecting block 117. A sliding groove 118 is opened inside the placement platform 1. A limiting rod 1110 is fixedly connected longitudinally at equal intervals inside the sliding groove 118. The Z-shaped plate 119 is slidably connected longitudinally inside the sliding groove 118 through the limiting rod 1110. A toggle plate 1111 is fixedly connected to the end of the Z-shaped plate 119 away from the connecting block 117.

[0024] In this implementation scheme, the motor 5 drives the pulley 7 and the V-belt 8, which in turn drive the rotating wheel 6 and the toothed ring 9 to rotate. When the toothed ring 9 engages with the toothed plate 10, it can push the backlight plate 4 to slide horizontally. When the toothed ring 9 disengages from the toothed plate 10, the backlight plate 4 slides in the opposite direction under the action of inertia and spring 114, ultimately realizing the reciprocating shaking of the backlight plate 4. This process allows the seeds to be evenly dispersed on the backlight plate 4, avoiding overlapping and accumulation, ensuring that the key characteristics such as the shape, color, and texture of each seed are fully presented, reducing measurement deviations caused by occlusion, and significantly improving the integrity of image acquisition and subsequent analysis. To ensure accuracy, under normal conditions, the elasticity of spring 114 keeps sliding column 113 at the center of limiting groove 111. Magnet 115 and magnet 216 magnetically attract each other to stably fix backlight panel 4 on the placement platform 1, preventing backlight panel 4 from shifting during shaking and ensuring image acquisition stability. When backlight panel 4 needs to be replaced, push the push plate 1111 in the groove 41 upwards. Z-shaped plate 119 slides longitudinally in sliding groove 118 through limiting bar 1110, causing magnet 216 to disengage from magnet 115, and backlight panel 4 can be easily removed, improving equipment practicality and work efficiency.

[0025] Specifically, the toggle plate 1111 is longitudinally slidably connected inside the groove 41, and the opposing surfaces of magnet 116 and magnet 115 have opposite magnetic properties. Magnet 116 is longitudinally slidably connected inside the backlight plate 4.

[0026] In this embodiment, the toggle plate 1111 is longitudinally slidably connected in the groove 41. The attraction or separation of magnet 116 and magnet 115 can be controlled by manual operation. The structure is simple and the operation is intuitive. The design of opposite magnetic properties ensures stable magnetic attraction and avoids accidental detachment of the backlight plate 4. At the same time, separation only requires overcoming the magnetic force and does not require complicated operation.

[0027] Specifically, the toothed ring 9 is not completely circular, the toothed plate 10 is fixedly embedded in the bottom of the backlight plate 4, and the rotating wheel 6 and the toothed ring 9 are rotatably connected inside the placement platform 1.

[0028] In this embodiment, the incompletely annular design of the toothed ring 9 allows it to periodically engage and disengage with the toothed plate 10 during rotation, thereby driving the backlight plate 4 to perform reciprocating linear motion. This intermittent shaking is more conducive to the uniform dispersion of seeds on the backlight plate 4, avoiding continuous unidirectional sliding that causes seeds to accumulate at the edges.

[0029] Specifically, a silicone column is fixedly connected to the top of magnet 2 116. Under normal conditions, the elasticity of the silicone column causes magnet 2 116 to slide towards magnet 1 115.

[0030] In this embodiment, the elasticity of the silicone pillar can push the second magnet 116 to automatically approach the first magnet 115 when the backlight panel 4 is installed, reducing manual alignment steps and improving installation efficiency. At the same time, the elastic buffer can prevent structural wear caused by rigid contact during magnetic attraction.

[0031] Specifically, under normal conditions, the elasticity of the spring 114 keeps the sliding post 113 located at the center of the limiting groove 111, and the top of the sliding post 113 extends to the upper surface of the placement platform 1.

[0032] In this embodiment, the elasticity of the spring 114 keeps the sliding column 113 in the center of the limiting groove 111, ensuring the precise magnetic attraction position of magnet 115 and magnet 116. During the shaking of the backlight panel 4, the spring 114 can absorb some of the vibration energy, reduce the impact on the internal structure of the placement platform 1, and extend the service life of the equipment.

[0033] The working principle and usage process of this utility model are as follows: In use, seeds are poured onto the backlight plate 4. Then, the motor 5 is started, and the motor 5 drives the rotating wheel 6 to rotate via the pulley 7 and V-belt 8. The rotating wheel 6 drives the toothed ring 9 to rotate. Through the meshing of the toothed ring 9 with the toothed plate 10, the backlight plate 4 can slide. When the toothed ring 9 is not meshed with the toothed plate 10, the elasticity of the spring 114 can drive the backlight plate 4 to slide in the opposite direction. This process repeats itself. The rotation of the toothed ring 9 is a horizontal reciprocating shaking process of the backlight plate 4, which can evenly disperse the seeds on the backlight plate 4. After dispersion, the detection results are directly input into the tablet 3 for display via the image acquisition device 2. When the backlight needs to be replaced... When the seeds on plate 4 are being removed, insert your hand into the groove 41 and apply an upward force to the actuating plate 1111. The actuating plate 1111 drives the connecting block 117 and the second magnet 116 to slide upward through the Z-shaped plate 119, causing the second magnet 116 to separate from the first magnet 115. After reducing the magnetism of the first magnet 115 and the second magnet 116, the backlight plate 4 can be easily removed. Then, pour out the seeds from the backlight plate 4, place the backlight plate 4 on the placement platform 1, and insert the sliding post 113 into the backlight plate 4. This will cause the first magnet 115 and the second magnet 116 to attract each other, thus completing the assembly between the sliding post 113 and the backlight plate 4. Then, pour new seeds onto the backlight plate 4 for testing.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
