Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable sorting technology, specifically to an image acquisition component for visual fruit and vegetable sorting. Background Technology

[0002] With consumers demanding increasingly stringent quality standards for fruits and vegetables, and the trend towards large-scale and intelligent development in the fruit and vegetable industry, higher standards are being set for the sorting of fruits and vegetables on conveyor belts. To comprehensively and accurately collect information on fruits and vegetables of different shapes and locations, the collection components must possess flexible and precise angle adjustment capabilities. Furthermore, vibration is a significant factor during the transport of fruits and vegetables via conveyor belts. The operation of the conveyor belt, the running of mechanical components, and the work of surrounding equipment all generate varying degrees of vibration. These vibrations can severely impact the stability of the collection components and the collection effect.

[0003] While existing acquisition components have implemented some vibration-resistant measures, such as the installation of damping rubber, their effectiveness remains limited in real-world applications. More critically, when the acquisition component is angled, the damping rubber often becomes incompatible with the adjusted component due to a mismatch in its thickness and other dimensional parameters. This significantly reduces the damping efficiency of the damping rubber in the adjusted state. In severe cases, the damping rubber may even resonate with external vibrations, leading to a substantial increase in the vibration amplitude of the acquisition component. This undoubtedly has a serious negative impact on the acquisition component's ability to obtain high-quality images, greatly interfering with its normal image acquisition operation. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the shock-absorbing components in the existing technical solutions cannot adaptively adjust with the angle adjustment of the acquisition components, and to provide an image acquisition component for visual fruit and vegetable sorting.

[0005] To address the shortcomings of the aforementioned technical problems, the present invention adopts the following technical solution: an image acquisition component for visual fruit and vegetable sorting, which has a support member for positioning and is equipped with a control component and a shock-absorbing component that cooperate with each other to adjust the camera angle while maintaining a shock-absorbing state.

[0006] The load-bearing component includes two support plates connected by support columns and sliding rails;

[0007] The shock absorption assembly includes an air spring mounted on a sliding rail, and the movable end of the air spring is provided with a connecting shaft;

[0008] The control component includes a support plate for connecting the camera. The support plate is hinged to the connecting shaft via a connecting plate to maintain the vibration damping state of the support plate. The end of the support plate away from the connecting plate is rotatably connected to the support column and is provided with a residual worm wheel. The residual worm wheel meshes with a worm gear provided on the sliding rail to adjust and lock the angle of the support plate.

[0009] As a further optimization of the image acquisition component for visual fruit and vegetable sorting of this utility model: a connecting sleeve is slidably provided in the sliding rail, one side of the connecting sleeve is rotatably connected to the worm gear, an air spring is fixedly provided on the side of the connecting sleeve away from the worm gear, and a positioning stud is threadedly connected to the connecting sleeve and located inside the hollow worm gear. The positioning stud can press against the sliding rail and limit the position of the connecting sleeve under the support of the connecting sleeve.

[0010] As a further optimization of the image acquisition component for visual fruit and vegetable sorting of this utility model: the cross-section of the sliding groove on the sliding rail is dovetail-shaped, and the connecting sleeve is a connecting frame that can slide and cooperate with the outer periphery of the sliding rail and the sliding groove.

[0011] As a further optimization of the image acquisition component for visual fruit and vegetable sorting of this utility model: the air spring includes a piston rod whose end is connected to a connecting shaft. The piston rod slides and compresses air in an air cylinder provided on a connecting sleeve, and the air cylinder is provided with tiny exhaust holes on the outer peripheral surface near the connecting sleeve.

[0012] As a further optimization of the image acquisition component for visual fruit and vegetable sorting of this utility model: two support columns are provided, which are arranged in parallel and in a triangular shape with the sliding rail.

[0013] As a further optimization of the image acquisition component for visual fruit and vegetable sorting of this utility model: both of the support columns are rotatably connected to a bearing plate.

[0014] As a further optimization of the image acquisition component for visual fruit and vegetable sorting of this utility model: the carrier plate is provided with a snap-fit ​​sleeve that snaps into the camera.

[0015] As a further optimization of the image acquisition component for visual fruit and vegetable sorting of this utility model: the inner wall of the snap-fit ​​sleeve is provided with an elastic rubber layer.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention connects a support plate in the control assembly to a connecting plate in the shock-absorbing assembly. The connecting plate is connected to an air spring via a shaft, allowing the air spring to effectively absorb and protect the support plate from vibration. When the support plate is protected by the air spring, the snap-fit ​​sleeve fixed to the support plate and the camera inside the snap-fit ​​sleeve are also protected, effectively preventing damage caused by vibration. Simultaneously, the support plate and support column are connected by a rotating mechanism, ensuring flexible rotation adjustment. The rotation adjustment function of the support plate, in conjunction with the worm gear on the connecting sleeve and the residual worm wheel on the support plate, achieves precise adjustment and locking. This makes adjusting the camera position more convenient and efficient for operators. Furthermore, as the camera adjustment is completed, the shock-absorbing assembly also undergoes a corresponding dimensional change, ensuring effective shock absorption for the adjusted camera.

[0021] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0022] like Figure 1 and Figure 2As shown, in the image acquisition component for visual fruit and vegetable sorting, the carrier component 1 is undoubtedly the core component of the entire system. It is not only a crucial hub connecting the transmission equipment, but also a solid foundation for the smooth positioning and image acquisition of the subsequent camera 3. The carrier component 1 cleverly incorporates a control component 2 connected to the camera 3; this component's design is ingenious. With its precise mechanical structure and reasonable layout, the control component 2 can accurately position the camera 3 to the optimal position on the transmission equipment, thus providing strong support for high-quality image acquisition. In practical applications, the position of the camera 3 plays a decisive role in the effect and accuracy of image acquisition, and the presence of the control component 2 ensures that the camera 3 is always in the ideal working position, greatly improving the quality and efficiency of image acquisition.

[0023] Of particular note is that the control component 2 is also connected to the shock-absorbing component 5 mounted on the support component 1. This shock-absorbing component 5 is designed to fully consider various vibration conditions that the equipment may encounter during operation. It can flexibly change position as the control component 2 is adjusted, and maintains excellent shock absorption throughout the positional changes, without being negatively affected. This means that no matter how the control component 2 adjusts the position of the camera 3, the shock-absorbing component 5 can continuously and stably provide reliable shock absorption protection for the camera 3, ensuring stable operation of the camera 3 under various complex working conditions and effectively avoiding problems such as decreased image acquisition quality due to vibration. Furthermore, the structural design of the support component 1 is equally ingenious. It includes two support plates 101 for secure mounting on the transmission equipment, which are tightly connected by two parallel support columns 102 and a sliding rail 103. From a spatial layout perspective, the two support columns 102 and the sliding rail 103 are arranged in a triangular pattern. This unique structural design not only significantly enhances the structural stability of the load-bearing component 1, enabling it to withstand greater external forces and vibrations, but also provides reasonable and sufficient space for the subsequent installation of the control component 2 and the shock absorption component 5, ensuring that the components can work together without interfering with each other.

[0024] A support plate 202, a crucial component of the control assembly 2, is rotatably mounted on the support column 102. The support plate 202 plays an indispensable role in the entire control assembly 2, its function being of paramount importance. A snap-fit ​​sleeve 201, which engages with the camera sleeve, is fixedly installed on the support plate 202. This snap-fit ​​method not only simplifies and speeds up the installation and removal of the camera 3, saving significant time and labor costs, but also provides reliable stability during camera 3 operation, effectively preventing image acquisition from being affected by shaking or displacement. Furthermore, the inner wall of the snap-fit ​​sleeve 201 has an elastic rubber layer, which further maintains the connection stability between the camera 3 and the snap-fit ​​sleeve 201, while also providing further shock absorption and protection for the camera 3. Meanwhile, a residual worm gear 203 is provided at the end of the bearing plate 202 facing the sliding rail 103. The residual worm gear 203 meshes with the worm 204 rotatably mounted on the connecting sleeve 6. The connecting sleeve 6 is slidably mounted on the sliding rail 103. Specifically, the cross-section of the groove on the sliding rail 103 is dovetail-shaped. The connecting sleeve 6 is a connecting frame that can slide and cooperate with the groove and the outer periphery of the sliding rail 103. That is, the connecting block is provided with a dovetail block at the groove. In addition, a positioning stud 4 is threadedly connected to the center of the connecting sleeve 6. That is, a screw hole is opened at the dovetail block for threaded connection with the positioning stud 4. When the positioning stud 4 is screwed into the connecting sleeve 6, it can press against the inner wall of the sliding rail 103 under the support of the connecting sleeve 6, thereby achieving precise positioning of the connecting sleeve 6. This provides great convenience for the staff to adjust the position of the camera 3 in the length direction of the sliding rail 103, and further assists the staff in performing detailed adjustment operations to meet different image acquisition needs. The worm gear 204 here is also uniquely designed, with its helix angle being smaller than the contact friction angle between the worm gear 204 and the residual worm wheel 203. This ingenious design detail allows staff to easily adjust the angle of the support plate 202 according to actual needs, and after adjusting to the appropriate angle, it can achieve precise positioning, ensuring that the position of the camera 3 will not change due to slight external interference, thereby guaranteeing the stability and accuracy of image acquisition.

[0025] An air spring 503 is installed on the side of the connecting sleeve 6 facing away from the worm gear 204. That is, an air spring 503 is provided on the side of the connecting frame facing away from the worm gear 204. As a key component of the shock absorption assembly 5, the air spring 503 operates based on the compressibility of air. A connecting shaft 502 is provided at the end of the air spring 503 facing away from the sliding rail 103. The connecting shaft 502 and the end of the bearing plate 202 facing away from the residual worm gear 203 are hinged together by a connecting plate 501. This connection method has many significant advantages. On the one hand, when the bearing plate 202 is adjusted at an angle, the synergistic effect of the air spring 503 and the connecting plate 501 ensures a smooth and slow adjustment process. This is because the air spring 503 generates a certain damping force during compression and extension, effectively slowing down the adjustment speed of the bearing plate 202, greatly reducing the risk of damage to the camera 3 inside the locking sleeve 201 due to excessive adjustment speed, and providing safer and more reliable protection for the camera 3. On the other hand, after the angle of the bearing plate 202 is adjusted, the air compression characteristics of the air spring 503, in conjunction with the connecting plate 501, can continuously exert a good shock absorption effect, ensuring that the shock absorption effect of the camera 3 is not affected after adjustment. Even if the equipment encounters severe vibration or impact during operation, the air spring 503 can efficiently absorb and buffer vibration energy through its own compression and extension, providing stable and reliable protection for the camera 3. At the same time, the arrangement of the connecting plate 501 and the air spring 503 can also ensure that the worm gear 204 and the residual worm wheel 203 maintain good meshing when adjusting the displacement on the sliding rail 103, ensuring the normal operation of the control component 2 and the effective realization of the adjustment function. Specifically, the air spring 503 includes a piston rod 5031 connected at one end to a connecting shaft 502. The piston rod 5031 is sealed and movably connected to an air cylinder 5032 mounted on a connecting sleeve 6. The air cylinder 5032 has a small exhaust hole 5033 on its outer periphery facing the connecting sleeve 6, communicating with the outside. This allows the piston rod 5031 to slide within the air cylinder 5032, generating a large damping force and effectively maintaining good shock absorption, providing all-around protection for the camera 3. Furthermore, two support plates 202 can be provided and rotatably connected to two support columns 102, facilitating the installation of the two cameras 3 into the two snap-fit ​​sleeves 201. This also allows the two support plates 202, together with the four connecting plates 501 and the connecting shaft 502, to form a stable, quadrilateral-like structure, further enhancing the shock absorption function for the two cameras 3.
