Description

Technical Field

[0001] This invention relates to the field of plant specimen production technology, and in particular to a specimen grasping and conveying system for plant specimen grasping and identification. Background Technology

[0002] In the field of plant specimen processing, plant specimens on paper carriers need to go through processes such as grasping, conveying, photographing and identifying, and classifying and storing. Most existing manufacturers use automated suction cup components in conjunction with conveying and identification devices to complete the above operations. That is, after stacking a stack of paper specimens, they are picked up one by one by the suction cup components, then transferred to the photographing and identification device, and finally classified and stored.

[0003] However, in practical applications, since the mounting paper is mostly made of thick cardboard, kraft paper and other materials with fibrous texture on the surface, and the plant specimens, adhesive tape and cotton thread pasted on the mounting paper will make the surface uneven, the airtightness between the suction cup and the mounting paper is poor, the suction power of the suction cup is limited, and it is very easy to have problems such as not being able to stick firmly during the suction stage, or only picking up a corner of the mounting paper.

[0004] Meanwhile, after the suction cup picks up the paper, the rigidity of the paper itself can easily cause the edges to curl during movement and rotation. The uneven force caused by the combined effects of the moving acceleration, the centrifugal force of rotation, and the positioning deviation of the suction cup can further damage the airtightness, causing vacuum leakage and resulting in the paper falling off.

[0005] Current solutions only involve optimizing the suction cup material and increasing the contact area, which cannot eliminate the core defect. The paper falling off the table not only affects work efficiency, but may also damage the specimen and cause equipment failure. Summary of the Invention

[0006] This invention provides a specimen grasping and conveying system for plant specimen grasping and identification, in order to solve the problems mentioned in the background art, such as poor airtightness of the suction cup and limited suction force due to the material and surface unevenness of the mounting paper, which makes it easy to fall off when the specimen is not firmly grasped.

[0013] The invention is further configured such that a sliding groove is provided at the bottom of the housing, the bottom of the limiting plate extends into the corresponding sliding groove, and a second driving screw is rotatably connected inside the sliding groove, one end of the second driving screw passing through the limiting plate and threadedly connected to it.

[0014] The present invention is further configured such that the lifting unit includes a support plate slidably connected to the housing, and limiting sliding openings are provided through the two ends of the housing corresponding to the two ends of the support plate. The two ends of the support plate extend to the inner wall of the limiting sliding opening and are slidably connected thereto. One side of the support plate extends between the limiting plate and the turntable. A connecting groove is provided through the outer wall of the support plate corresponding to the position of the movable rod. The movable rod is engaged in the inner wall of the connecting groove and is slidably connected thereto.

[0015] The invention is further configured such that a connecting plate is provided at the bottom of the bearing plate away from the adjusting slide plate, a support plate is hinged to the bottom of the connecting plate, a conveyor belt is provided on the side of the support plate near the adjusting slide plate, the height of the conveyor belt is lower than the suction cup, an auxiliary wheel is rotatably installed on the outer wall of the connecting plate near the conveyor belt, a plurality of mounting seats are provided on the side of the support plate away from the conveyor belt, an elastic element is hinged inside the mounting seat, the top end of the elastic element is hinged to the connecting plate, a fixing rod is provided between the mounting seats, and a top plate is provided near the middle position of the fixing rod.

[0016] The beneficial effects of the specimen grasping and conveying system for plant specimen grasping and identification of the present invention are as follows: 1. Improve specimen gripping stability and solve the problems of falling and shifting. The main frame provides a stable foundation, and the feeding unit stably supplies specimens. The support plate and docking slide precisely adjust the position of the gripping unit, and the docking rod prevents the gripping unit from falling and shaking, ensuring that the suction cup can smoothly adsorb the specimen. The lifting unit and suction cup are linked. The support plate drives the conveyor belt to support the specimen, and the drive screw drives the adjusting slide to pull the specimen to the conveyor belt, forming a double fixation of the suction cup and the conveyor belt. The auxiliary wheel soft brush protects the specimen and increases friction, further improving stability.

[0017] 2. Improve specimen positioning and identification accuracy. The gripping unit and the identification unit work together. The support plate and the docking slide move the specimen precisely above the conveying unit. The suction cup smoothly releases its grip, and the specimen is lifted by the conveyor belt. After the top plate and the docking plate dock, the support plate slowly flips over, and the specimen slides down the inclined plane to the conveying unit, ensuring consistent positioning and providing a precise working position for the identification components, thus improving identification accuracy.

[0018] 3. Enhanced system adaptability and expanded application range. The internal components of the gripping unit are linked, and the drive motor drives the gears and turntable to rotate, causing the movable rod to move and adjust the suction cup spacing; the movable rod simultaneously drives the lifting unit to adjust the tray spacing, and the extended design of the top plate ensures that it can still accurately align with the docking plate after the spacing is adjusted, which can flexibly adapt to specimens of different sizes.

[0025] Please see Figure 1 - Figure 8A specimen grasping and conveying system for plant specimen grasping and identification includes a main frame 1, a feeding unit 11 is arranged inside the main frame 1 near one end, a receiving unit 12 is arranged inside the main frame 1 near the other end, an identification unit 3 is arranged inside the main frame 1 near the receiving unit 12, and a transfer device 2 is arranged inside the main frame 1 above the feeding unit 11. The transfer device 2 includes a mounting rod 21 fixedly connected to the main frame 1. A support plate 22 is slidably connected inside the mounting rod 21. A docking slide plate 23 is slidably connected inside the support plate 22. A gripping unit 24 is provided at the bottom of the docking slide plate 23. A drive screw 221 is rotatably connected inside the support plate 22. One end of the drive screw 221 passes through the docking slide plate 23 and is threadedly connected to it. The gripping unit 24 includes a housing 241 slidably connected to the docking slide plate 23. An adjustable slide plate 242 is slidably installed inside the housing 241. Lifting units 245 are provided on both sides of the adjustable slide plate 242 inside the housing 241. A limit plate 2421 is fixedly installed at the bottom of the adjustable slide plate 242. A positioning port 2424 is opened at the top of the adjustable slide plate 242, above the limit plate 2421. A turntable 243 is rotatably connected inside the positioning port 2424. A drive groove 2431 is opened through the top of the turntable 243. A positioning groove 2422 is opened through the top of the limit plate 2421 at the position corresponding to the drive groove 2431. A movable rod 244 is slidably connected inside the drive groove 2431. The bottom end of the movable rod 244 extends through the positioning groove 2422 to the outer wall of the housing 241. A suction cup 2441 is provided at the bottom end of the movable rod 244.

[0026] By adopting the above technical solutions, the linear layout of the main frame 1 enables the feeding unit 11, receiving unit 12, and identification unit 3 to form a complete workflow. The proximity of the identification unit 3 to the receiving unit 12 reduces unnecessary movement and improves operational continuity. The three-stage motion system of the transfer device 2 is highly efficient and coordinated. The mounting rod 21 provides stable support, and the orthogonal layout of the support plate 22, docking slide plate 23, and drive screw 221 allows the gripping unit 24 to accurately cover the entire working area. The components of the gripping unit 24 are closely linked. The cam mechanism formed by the turntable 243 and the movable rod 244, the constraint of the limit plate 2421, and the driving of the adjusting slide plate 242 ensure coordinated movement between the suction cup 2441 and the lifting unit 245. The drive motor 2426 synchronously controls the suction and lifting adjustment, improving the adaptability to specimens of different sizes.

[0027] The identification unit 3 includes a fixed frame 31 that is fixedly connected to the inner wall of the main frame 1. An identification component 32 is provided on the top of the fixed frame 31. A conveying unit 33 is provided on the inner side of the fixed frame 31 below the identification component 32. A docking plate 34 is symmetrically provided on both sides of the conveying unit 33.

[0028] By adopting the above technical solution, the fixed frame 31 is rigidly connected to the main frame 1 to form a stable support. The integrated identification component 32 and the conveying unit 33 form an integrated module. The vertical layout efficiently utilizes space and ensures smooth connection between the identification and conveying processes. The identification component 32 is precisely vertically aligned with the conveying unit 33 through the fixed frame 31, avoiding identification errors caused by parallax. The docking plate 34 of the conveying unit 33 is linked with the top plate 2458 of the gripping unit 24 to achieve seamless connection between specimen conveying and receiving. Its dynamic docking mechanism can ensure the accuracy of specimen positioning. A docking rod 2411 is provided on the top of the housing 241 at the position corresponding to the docking slide plate 23. The top end of the docking rod 2411 passes through the docking slide plate 23 and the two are slidably connected. A pushing component 231 is provided on the top of the docking slide plate 23, and the output end of the bottom of the pushing component 231 is fixedly connected to the housing 241. The outer wall of the turntable 243 is provided with docking teeth 2433. A gear 2425 is rotatably installed inside the positioning port 2424 near the turntable 243. The gear 2425 is meshed with the docking teeth 2433. A drive motor 2426 is provided on the top of the adjusting slide plate 242 at the position corresponding to the position near the gear 2425. The output end of the drive motor 2426 is fixedly connected to the gear 2425. A connection port 2432 is provided on the top of the turntable 243. A connecting shaft 2423 is provided on the top of the limiting plate 2421 at the position corresponding to the connection port 2432. The top end of the connecting shaft 2423 passes through the connection port 2432 and the two are rotatably connected. The bottom of the housing 241 is provided with a sliding groove 2413, and the bottom of the limiting plate 2421 extends into the corresponding sliding groove 2413. A second drive screw 2414 is rotatably connected inside the sliding groove 2413. One end of the second drive screw 2414 passes through the limiting plate 2421 and is threadedly connected to it.

[0029] By adopting the above technical solution, the docking rod 2411 and the pushing component 231 work together to form a linear motion mechanism, enabling precise lifting and lowering of the gripping unit 24, ensuring that the suction cup 2441 is perpendicularly aligned with the specimen surface without any swaying deviation. The related components of the turntable 243 are highly interconnected. The gear 2425, docking gear 2433, connecting shaft 2423, drive groove 2431, and movable rod 244 work together to synchronously control the spacing adjustment of multiple suction cups 2441 via a single drive motor 2426, achieving high adjustment precision. The limiting plate 2421 plays a dual guiding role, working in conjunction with the turntable 243 and adjusting slide plate 242 to both constrain the rotation trajectory of the turntable 243 and ensure the stable translation of the adjusting slide plate 242. The second drive screw 2414 works in conjunction with the limiting plate 2421 and the slide groove 2413 to achieve precise horizontal fine-tuning of the adjusting slide plate 242, compensating for specimen position deviations. The two systems work synchronously, adapting to specimens of different sizes while maintaining a symmetrical distribution of gripping force. The standard interface reserved in the fixed frame 31 supports the quick replacement of the identification component 32, adapting to multi-level detection needs.

[0030] The lifting unit 245 includes a support plate 2451 slidably connected to the housing 241. Limiting slots 2412 are provided through the two ends of the housing 241 at the positions corresponding to the two ends of the support plate 2451. The two ends of the support plate 2451 extend to the inner wall of the limiting slots 2412 and are slidably connected thereto. One side of the support plate 2451 extends between the limiting plate 2421 and the turntable 243. A connecting groove 2452 is provided through the outer wall of the support plate 2451 at the position corresponding to the movable rod 244. The movable rod 244 is engaged in the inner wall of the connecting groove 2452 and is slidably connected thereto. A connecting plate 2453 is provided at the bottom of the support plate 2451 away from the adjusting slide plate 242. A support plate 2454 is hinged to the bottom of the connecting plate 2453. A conveyor belt 2455 is provided on the side of the support plate 2454 near the adjusting slide plate 242. The height of the conveyor belt 2455 is lower than that of the suction cup 2441. An auxiliary wheel 24531 is rotatably installed on the outer wall of the connecting plate 2453 near the conveyor belt 2455. Several mounting seats 2456 are provided on the side of the support plate 2454 away from the conveyor belt 2455. An elastic element 2459 is hinged inside the mounting seat 2456. The top of the elastic element 2459 is hinged to the connecting plate 2453. A fixing rod 2457 is provided between the mounting seats 2456. A top plate 2458 is provided near the middle of the fixing rod 2457.

[0031] By adopting the above technical solution, the supporting plate 2451 works in coordination with the shell 241 and the movable rod 244. Through the limiting slide 2412 and the connecting groove 2452, the horizontal distance between the support plate 2451 and the suction cup 2441 is adjusted in coordination, and the vertical power is transmitted to drive the movement of the support plate 2454. The support plate 2454 works in coordination with the connecting plate 2453, the elastic element 2459, the conveyor belt 2455, the auxiliary wheel 24531, and the fixing rod 2457 to achieve both flipping and automatic reset, as well as providing stable dynamic support and rigid reinforcement. The top plate 2458 works in coordination with the docking plate 34 to guide the support plate 2454 to unfold at a uniform speed, ensuring accurate positioning of the specimen during sliding. The elastic element 2459 works in coordination with the mounting base 2456 and the connecting plate 2453 to achieve a dynamic balance of lifting, shock absorption, and rapid reset, improving the stability of the movement.

[0032] Working principle and usage process of this invention: When using this system, the plant specimens are first fed into the main frame 1 through the feeding unit 11. After the feeding preparation is completed, the horizontal position of the gripping unit 24 is precisely adjusted by the coordinated action of the support plate 22 and the docking slide plate 23, which drives the gripping unit 24 to move towards the feeding unit 11 until the suction cup 2441 at the bottom of the gripping unit 24 is aligned with the designated position of the specimens stacked on the feeding unit 11, effectively ensuring the accuracy of gripping and positioning and avoiding subsequent gripping deviation.

[0033] Subsequently, the pushing component 231 on the top of the docking slide 23 is activated, pushing the gripping unit 24 to fall smoothly and gradually approach the specimen surface. During this process, the docking rod 2411 can effectively limit the falling trajectory of the gripping unit 24, avoid the gripping unit 24 from shaking when falling, further improve the gripping stability, and prevent the suction cup 2441 from failing to accurately align with the specimen due to shaking.

[0034] After the gripping unit 24 falls to the designated position, the suction cup 2441 adheres to the specimen surface and generates suction force through negative pressure. At the same time, the support plate 2454 of the lifting unit 245 drives the conveyor belt 2455 to move synchronously to a position close to the edge of the specimen, achieving initial positioning and support of the specimen. When the suction cup 2441 successfully adsorbs the specimen, the drive screw 2414 starts and rotates, driving the adjusting slide plate 242 to move horizontally. By moving the adjusting slide plate 242, the specimen is pulled, and one end of the specimen is smoothly pulled onto the conveyor belt 2455. At this time, the conveyor belt 2455 starts to operate, working in conjunction with the suction cup 2441 to pull the specimen until the adjusting slide plate 242 moves between the connecting plates 2453, so that both sides of the specimen are smoothly attached to the conveyor belt 2455, while the middle of the specimen is continuously adsorbed and fixed by the suction cup 2441, achieving double fixation of the specimen and effectively preventing the specimen from falling during the pulling process.

[0035] During the specimen pulling process, the auxiliary wheel 24531 plays an auxiliary conveying role. The surface of the auxiliary wheel 24531 is equipped with a soft brush, which can not only avoid scratching and damaging the plant specimen, but also increase the friction between the specimen and the conveyor belt 2455 by slightly pressing the surface of the specimen with the soft brush, so that the specimen is conveyed more smoothly and avoids the situation of conveying jams or specimen deviation.

[0036] After the specimen is secured, the gripping unit 24 and the secured specimen are moved toward the identification unit 3 by the coordinated action of the support plate 22 and the docking slide plate 23 until the specimen is precisely positioned above the conveying unit 33. Then, the push assembly 231 is activated again, controlling the gripping unit 24 to slowly fall. During the fall, the suction cup 2441 stops generating negative pressure, releasing the suction on the specimen. At this time, the entire specimen is smoothly supported by the conveyor belt 2455, preventing the specimen from falling due to the sudden loss of suction.

[0037] As the gripping unit 24 continues to fall, the top plate 2458 in the lifting unit 245 precisely aligns with the docking plates 34 on both sides of the conveying unit 33. As the gripping unit 24 continues to fall, the docking plates 34 exert an upward pushing force on the top plate 2458, causing the support plate 2454 to slowly flip downwards with its hinge point with the connecting plate 2453 as the center. During the flipping process, the support plate 2454 gradually unfolds smoothly, and the specimen slowly slides down the inclined surface formed by the unfolded support plate 2454 onto the conveying unit 33. This slow falling method can effectively ensure the consistency of the specimen's position when it falls onto the conveying unit 33, providing convenience for the subsequent identification operation of the identification unit 3 and improving the identification accuracy.

[0038] After the specimen is successfully placed on the conveying unit 33, the gripping unit 24 rises and resets. At the same time, the elastic element 2459 in the lifting unit 245 generates an elastic thrust, pushing the tray 2454 to flip upward and reset. The other components inside the gripping unit 24 also reset synchronously, preparing for the next specimen gripping operation.

[0039] The conveying unit 33 is started, which moves the specimen directly below the identification component 32. When the specimen arrives at the identification station, the identification component 32 takes a picture of the specimen for identification. After the identification is completed, the conveying unit 33 continues to operate and conveys the identified specimen to the receiving unit 12, completing the entire process of grabbing, conveying, identifying and storing a single specimen. The above steps are repeated to realize the continuous processing of stacked specimens.

[0040] When processing specimens of different sizes, the gripping unit 24 can be flexibly adjusted to suit the gripping needs of specimens of different sizes. During adjustment, the drive motor 2426 is started first. The output end of the drive motor 2426 drives the gear 2425 to rotate. During the rotation of the gear 2425, the mating teeth 2433 that mesh with it drive the turntable 243 to rotate counterclockwise. When the turntable 243 rotates counterclockwise, the drive groove 2431 on its surface generates a squeezing force on the movable rod 244, causing the movable rod 244 to move smoothly along the positioning groove 2422 on the limiting plate 2421. This, in turn, causes the suction cups 2441 at the bottom of the movable rod 244 to gather or disperse, adjusting the distance between the suction cups 2441 to adapt to the adsorption needs of specimens of different widths.

[0041] During the movement of the movable rod 244, the entire lifting unit 245 moves synchronously through its locking groove 2452, thereby adjusting the distance between the two side support plates 2454. This ensures that the adjustment of the support plates 2454 and the suction cup 2441 is synchronized, guaranteeing that the support plates 2454 can accurately lift specimens of different sizes. At the same time, the top plate 2458 is designed with a relatively long structure, so that even after the spacing of the support plates 2454 is adjusted, it can still accurately dock with the docking plate 34 when falling, ensuring the smoothness of the flipping and unfolding action and further improving the versatility and adaptability of the system.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
