Technical Field

[0001] This utility model relates to the field of robot feeding equipment technology, and in particular to an automatic feeding structure for a sorting robot. Background Technology

[0002] In the fields of modern industrial production and logistics warehousing, sorting robots have become key equipment for improving operational efficiency due to their high efficiency and precision. As the "front-end hub" of material supply, the automatic feeding structure directly affects the operational efficiency of the entire sorting system.

[0003] However, in existing technologies, the automatic feeding structure of sorting robots mostly adopts a combination of fixed mechanical limit and single conveying device. When faced with materials with irregular shapes and large size differences, the traditional fixed limit structure is difficult to achieve accurate positioning, resulting in low robot grasping success rate, frequent grasping deviation and material falling, which seriously affects sorting efficiency and accuracy. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing an automatic feeding structure for a sorting robot.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic feeding structure for a sorting robot, including a support base and a feeding robot arm, a placement platform is fixedly installed on one side of the support base, a roller feeding mechanism is provided at one end of the placement platform, a positioning adjustment mechanism is provided at the upper end of the roller feeding mechanism, and the roller feeding mechanism includes a support frame.

[0006] The positioning and adjustment mechanism includes two sets of long seats and a fixed plate. A servo motor is fixedly installed at the lower end of the fixed plate. Two sets of guide plates are set in the middle of the two sets of long seats. A movable plate is rotatably installed through the upper end of the fixed plate. Two sets of connecting parts are rotatably installed at the upper end of the movable plate. Two sets of sliding seats are slidably installed at the upper end of the fixed plate.

[0010] Preferably, multiple sets of rolling cylinders are rotatably installed in the middle of the support frame, a power component is fixedly installed on one side of the support frame, and a transmission component is installed on the outer wall of the multiple sets of rolling cylinders.

[0011] Preferably, the output end of the power component is fixed to the input end of the transmission component, and one end of the support frame is fixed to one end of the placement platform.

[0012] Preferably, the lower end of the feeding robot arm is fixed to the upper end of the support base.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a positioning adjustment mechanism, with the cooperation of a servo motor, a movable plate, two sets of connecting parts and two sets of sliding seats, the two sets of sliding seats can be driven to move, so that the two sets of sliding seats can move on the fixed plate.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] 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 present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides an automatic feeding structure for a sorting robot, including a support base 1 and a feeding robot arm 11. A placement platform 12 is fixedly installed on one side of the support base 1. A roller feeding mechanism 2 is provided at one end of the placement platform 12. A positioning adjustment mechanism 3 is provided at the upper end of the roller feeding mechanism 2. The roller feeding mechanism 2 includes a support frame 21.

[0024] The positioning adjustment mechanism 3 includes two sets of long seats 31 and a fixed plate 32. A servo motor 34 is fixedly installed at the lower end of the fixed plate 32. Two sets of guide plates 35 are arranged in the middle of the two sets of long seats 31. A movable plate 37 is rotatably installed through the upper end of the fixed plate 32. Two sets of connecting parts 38 are rotatably installed at the upper end of the movable plate 37. Two sets of sliding seats 39 are slidably installed at the upper end of the fixed plate 32. Push rods 310 are slidably installed in the two sliding channels at one end of the two sets of long seats 31. One end of the two sets of sliding seats 39... Two sets of L-shaped push plates 36 are fixedly installed on each of the four sets of push rods 310. Two sets of connecting blocks 33 are fixedly installed on the upper end of the fixed plate 32. One end of each set of push rods 310 is fixed to one end of a set of guide plates 35. The other ends of the four sets of push rods 310 are fixed to one end of the four sets of L-shaped push plates 36 respectively. The lower ends of the two sets of long seats 31 are fixed to the upper end of the support frame 21. The output end of the servo motor 34 is fixed to the lower end of the movable plate 37. The upper ends of the two sets of connecting blocks 33 are fixed to the lower end of the support frame 21.

[0025] The specific settings and functions of this embodiment are described below. The two sets of long seats 31 serve as the basic support structure and are fixedly installed on the support frame 21 to provide a stable support platform for subsequent sliding and positioning operations. Each set of long seats 31 has a sliding channel at one end for sliding insertion of the push rod 310. Its internal structure design ensures the smoothness and stability of the sliding of the push rod 310.

[0026] As a key connecting component, the fixed plate 32 is firmly connected to the support frame 21 through two sets of connecting blocks 33. Specifically, the two sets of connecting blocks 33 are fixed at specific positions on the fixed plate 32, and their upper ends are tightly fixed to the lower end of the support frame 21. This connection method not only enhances the stability of the fixed plate 32, but also ensures the reliable connection between the entire positioning adjustment mechanism 3 and other parts of the roller feeding mechanism 2. The servo motor 34 is fixedly installed at the lower end of the fixed plate 32 and serves as the power source for the entire positioning adjustment process. The servo motor 34 has the characteristics of high precision and high response speed, and can provide stable and accurate power output for positioning adjustment.

[0027] The movable plate 37 is rotatably mounted on the fixed plate 32. Its rotation center is precisely designed and machined to ensure the flexibility and accuracy of rotation. The output end of the servo motor 34 is fixedly connected to the lower end of the movable plate 37. When the servo motor 34 is running, it can accurately transmit the rotational power to the movable plate 37, driving the movable plate 37 to rotate precisely on the upper end of the fixed plate 32.

[0028] Both sets of connecting parts 38 are rotatably mounted on the upper end of the movable plate 37. The rotatable connection method adopts a high-precision bearing or hinge structure to ensure flexible rotation and good stability during movement. The two sets of sliding seats 39 are slidably mounted on the upper end of the fixed plate 32. A high-precision slide rail and slider cooperation structure is provided between them and the fixed plate 32 to ensure the smoothness and accuracy of the sliding seats 39 sliding on the fixed plate 32. The other ends of the two sets of connecting parts 38 are rotatably mounted on the upper ends of the two sets of sliding seats 39 respectively. In this way, during the rotation of the movable plate 37, the motion is converted into linear sliding of the two sets of sliding seats 39 on the fixed plate 32 through the two sets of connecting parts 38.

[0029] L-shaped push plates 36 are fixedly installed at one end of each of the two sets of sliding seats 39. The special shape design of the L-shaped push plates 36 enables them to provide stable and reliable thrust when pushing the push rods 310. One end of each of the four sets of push rods 310 is slidably inserted into the interior of the two sets of long seats 31, and the other end is fixedly connected to one end of each of the two sets of L-shaped push plates 36. When the two sets of L-shaped push plates 36 move under the drive of the sliding seats 39, they can synchronously drive the four sets of push rods 310 to slide inside the two sets of long seats 31. Each pair of push rods 310 is fixedly connected to one end of a set of guide plates 35. Through the synchronous sliding of the four sets of push rods 310, the synchronous movement of the two sets of guide plates 35 can be realized, thereby precisely adjusting the distance between the two sets of guide plates 35.

[0030] In practical applications, when dealing with materials of different specifications, the servo motor 34 is controlled to operate. The servo motor 34 precisely controls the rotation angle and speed according to a preset program. The movable plate 37 rotates under the drive of the servo motor 34. Through two sets of connecting parts 38, it drives two sets of sliding seats 39 to slide on the fixed plate 32, thereby causing two sets of L-shaped push plates 36 to push four sets of push rods 310 to move. The four sets of push rods 310 drive two sets of guide plates 35 to move, ultimately achieving precise adjustment of the distance between the two sets of guide plates 35 to adapt to the size of the material and achieve precise positioning of the material. This design not only meets the positioning needs of diverse materials, but also greatly improves the accuracy and stability of positioning through the precise cooperation and transmission between various components, providing a reliable guarantee for the efficient and precise grasping of the sorting robot.

[0031] Example 2: Figure 1 , Figure 2 and Figure 4 As shown, a placement platform 12 is fixedly installed on one side of the support base 1, multiple sets of rolling cylinders 22 are rotatably installed in the middle of the support frame 21, a power component 23 is fixedly installed on one side of the support frame 21, a transmission component 24 is installed on the outer wall of the multiple sets of rolling cylinders 22, the output end of the power component 23 is fixed to the input end of the transmission component 24, one end of the support frame 21 is fixed to one end of the placement platform 12, and the lower end of the loading robot arm 11 is fixed to the upper end of the support base 1.

[0032] The overall effect of this embodiment is that the support frame 21 serves as the basic frame of the entire material conveying structure. The support frame 21 is made of high-strength metal material, and its structural design takes into account both stability and spatial adaptability. In the middle position of the support frame 21, there are multiple sets of mounting holes for installing the rolling cylinders 22 at equal intervals. These mounting holes are precisely machined to ensure that the rolling cylinders 22 remain parallel and evenly spaced after installation, thus ensuring the smooth conveying of materials.

[0033] The rolling drums 22 are the direct carriers for material conveying. Their number is set according to actual conveying needs, and they are all made of high-strength and wear-resistant materials. Each set of rolling drums 22 is installed in the mounting holes of the support frame 21 through bearings. This installation method allows the rolling drums 22 to rotate flexibly inside the support frame 21, while effectively reducing frictional resistance during rotation. The outer wall of the rolling drums 22 is specially treated and has a certain roughness to enhance the friction between it and the material and prevent the material from slipping during conveying.

[0034] The transmission assembly 24 consists of multiple sets of synchronous pulleys and synchronous belts, which are installed on the outer wall of the rolling drum 22. Specifically, a synchronous pulley is fixedly installed at one end of each rolling drum 22, and multiple sets of synchronous pulleys are connected in sequence by the synchronous belt to form a complete transmission system. This transmission method has the advantages of high transmission efficiency, accurate transmission ratio, and smooth operation, and can ensure that multiple sets of rolling drums 22 remain synchronized during rotation. The power assembly 23 uses a high-precision, high-torque motor, which is installed on one side of the support frame 21. The output shaft of the motor is fixedly connected to one of the synchronous pulleys in the transmission assembly 24. As the power source of the entire conveying system, the power assembly 23 is equipped with a dedicated motor driver, which can accurately adjust the speed and direction of the motor according to the instructions of the control system to meet the conveying needs of different materials. It can slowly convey materials to the placement table 12, which can further improve the positioning accuracy and ensure that the loading robot arm 11 can accurately grab materials and improve sorting efficiency.

[0035] The placement platform 12 is designed to catch materials so that the subsequent feeding robot arm 11 can accurately pick up the materials. The feeding robot arm 11 is designed to pick up the materials on the placement platform 12, making it convenient to feed the materials.

[0036] The usage and working principle of this device are as follows: First, the automatic feeding structure is installed at one end of a suitable conveyor belt, and the material can fall stably onto the rolling drum 22 inside the support frame 21. Then, the positioning adjustment mechanism 3 is adjusted according to the shape of the material. By controlling the operation of the servo motor 34, the servo motor 34 precisely controls the rotation angle and speed according to a preset program. The movable plate 37 rotates under the drive of the servo motor 34, and through the two sets of connecting parts 38, it drives the two sets of sliding seats 39 to slide on the fixed plate 32, thereby causing the two sets of L-shaped push plates 36 to push. The four sets of push rods 310 move, driving the two sets of guide plates 35 to move, ultimately achieving precise adjustment of the distance between the two sets of guide plates 35. Finally, by running the power component 23, the power component 23 drives multiple sets of rolling drums 22 to rotate together through the transmission component 24. All sets of rolling drums 22 rotate inside the support frame 21, thereby driving the material to move and slowly conveying the material to the placement table 12. Then, the loading robot arm 11 is controlled to run, and the loading robot arm 11 will grab the material on the placement table 12 and take it away, improving sorting efficiency.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. 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 the technical solution of this utility model shall still fall within the protection scope of this utility model.
