Description

Technical Field

[0001] This utility model discloses a material supply structure for automated training and teaching, which relates to the field of automated training and teaching equipment technology. Background Technology

[0002] In the field of automated training, material feeding structures, as one of the key teaching devices, are widely used in simulating material conveying, sorting, and assembly processes in industrial production. Existing material feeding structures typically employ simple mechanical transmissions or single pneumatic control methods. While they can achieve basic material supply functions, they still have many shortcomings in practical applications. For example, traditional material feeding structures have low material transfer efficiency, making it difficult to meet the needs of multi-station, high-precision training. Furthermore, their structural design is relatively complex, resulting in high maintenance costs and insufficient flexibility, making them unable to adapt to material supply tasks of different shapes and sizes. In addition, existing material feeding structures are prone to problems such as material jamming and leakage during material transfer, affecting the continuity and stability of training.

[0003] On the other hand, with the rapid development of automation technology, practical training places higher demands on the functionality of material supply structures. Traditional material supply equipment often lacks modular design, making it difficult to achieve multi-station collaborative operation and adapt to different training scenarios. Furthermore, the precise positioning and rapid transfer capabilities of existing technologies still need improvement, especially in applications requiring frequent changes in material supply positions, where the response speed and positioning accuracy of traditional equipment often fall short of ideal results. Therefore, developing a compact, easy-to-operate material supply structure capable of efficient material transfer and multi-station collaboration has become a pressing technical challenge in the field of automated practical training. Utility Model Content

[0004] This utility model aims to solve the above problems through innovative structural design, and provide a high-efficiency material supply structure suitable for automated practical training, so as to meet the needs of modern practical training for equipment flexibility and stability.

[0005] This utility model provides a feeding structure for automated training and teaching, which includes a first automatic turntable, a second automatic turntable, a sliding component, a material container, a material transfer nozzle, a second cylinder, a mechanical limiting component, a base plate, and a support platform. Wherein:

[0006] The first automatic turntable is mounted on a first support platform, on which multiple circumferentially distributed material receiving stations are arranged. The first automatic turntable is driven by a motor to rotate and stops at a predetermined position to complete precise positioning. Further, the first automatic turntable can be an electric or pneumatic turntable.

[0007] The second automatic turntable is also mounted on the first support platform, and a first cylinder is installed on it. The second automatic turntable works in conjunction with the first automatic turntable to cooperate with the first cylinder in completing the material transfer operation. In particular, the rotation of the second automatic turntable is synchronized with that of the first automatic turntable to ensure the continuity of the material transfer process.

[0008] The sliding assembly and the second cylinder constitute a pneumatic transfer feeding mechanism, which is used to transfer materials from the material drop channel (19) to the suction nozzle picking station. Specifically, the sliding assembly consists of a sleeve-type slide rail and a sliding plate that slides within the slide rail. The sliding plate is provided with a material transfer storage hole, which is a stepped through hole that is larger at the top and smaller at the bottom. The upper end is designed with a trumpet-shaped structure to facilitate the smooth falling of materials; the lower end is connected to a material suction pipe for fixing the materials. The sliding plate is driven by the second cylinder to reciprocate along the slide rail, so that the material transfer storage hole can switch between the picking station of the material transfer suction nozzle and the position directly below the material drop channel.

[0009] The material container is installed above the feeding structure, and its bottom is provided with a material discharge channel that extends into the slide rail. The material container is equipped with a feeding mechanism, including a feeding motor and a feeding plate. The feeding plate is directly or indirectly fixed to the motor shaft of the feeding motor and is used to feed material from inside the container to the material discharge channel.

[0010] The material transfer nozzle is mounted on the first cylinder. The up-and-down movement of the first cylinder transfers material from the material transfer storage hole of the pneumatic transfer feeding mechanism to the corresponding material receiving station. Furthermore, the suction force of the material transfer nozzle is provided by a vacuum generator.

[0011] The second cylinder is connected to the slide plate and is used to drive the slide plate to reciprocate along the slide rail to realize the position switching of the material transfer storage hole, and ensure that the slide plate stops at the predetermined position and aligns with the material transfer nozzle or the material discharge channel.

[0012] The mechanical limiting assembly, mounted on the second support platform, includes a base plate, a limiting rod, a spring, and a nut. The base plate has a guide hole parallel to the sliding path of the slide plate. The limiting rod slides within the guide hole, with its front end facing the rear end of the slide plate. The spring's two ends abut against the nut and the base plate, respectively, to limit the slide plate's range of motion and prevent overshoot. Furthermore, the length of the limiting rod and the spring constant can be adjusted according to actual needs to accommodate different specifications of slide plates and rail systems.

[0013] The base plate serves as the foundation of the entire feeding structure, fixing the first and second support platforms. The first support platform is used to mount the first and second automatic turntables, while the second support platform is used to mount the slide rail, the second cylinder, and the mechanical limit assembly. The base plate is made of high-strength material and is fixed to the ground or experimental platform with bolts or other fasteners to enhance the stability of the overall structure.

[0014] The technical effects of this utility model are as follows:

[0015] The coordinated operation of the feeding mechanism and sliding components enables continuous and stable material feeding, solving the problem of low feeding efficiency in traditional feeding structures. Furthermore, the combined use of the first and second automatic turntables ensures precise positioning of the material receiving station and the material transfer nozzle, effectively improving feeding accuracy. In addition, the application of mechanical limit components effectively prevents overshooting of the sliding plate, enhancing the safety of equipment operation. The overall structure is compact and reasonable, with optimized component layout, saving space while simplifying the operation process and improving teaching efficiency.

[0016] In summary, this utility model provides a material supply structure for automated training and teaching. By integrating multiple automated components, it achieves efficient, accurate, and safe material supply, transfer, and receiving functions, making it particularly suitable for automated training and teaching scenarios and possessing broad application prospects.

[0026] This utility model provides a material feeding structure for automated practical training, which achieves efficient, accurate, and safe material feeding, transfer, and receiving functions through the coordinated work of multiple automated components. The following description, in conjunction with the appendix... Figures 1 to 5 The specific embodiments of this utility model will be described in detail.

[0027] The base plate 1 is the fundamental component of the entire feeding structure. It is made of high-strength aluminum alloy and its bottom is bolted to the experimental platform to ensure the stability of the overall structure. A first support platform 2 and a second support platform 15 are mounted on the base plate 1. The first support platform 2 supports the first automatic turntable 3 and the second automatic turntable 6, while the second support platform 15 is used to mount the slide rail 10, the second cylinder 11, and the mechanical limit assembly 12. Both the first support platform 2 and the second support platform 15 are connected to the base plate 1 by bolts, and a level is used during assembly to ensure accurate positioning of each component.

[0028] The first automatic turntable 3 is fixed to the top of the first support platform 2. It can be either an electric or pneumatic turntable, and the specific model can be determined according to actual needs. The rotation angle of the first automatic turntable 3 is set and controlled by a Siemens 1200 controller, which can achieve precise angle positioning. Multiple material receiving stations 4 are installed on the top of the first automatic turntable 3. These stations 4 are equidistantly distributed circumferentially on the turntable surface, and each station 4 is designed to be detachable, making it easy to replace different specifications of stations according to different training needs. The rotation of the first automatic turntable 3 is driven by a stepper motor. The output shaft of the motor is connected to the turntable through a reducer, thereby ensuring smooth operation and high positioning accuracy of the turntable. When the first automatic turntable 3 receives a command from the control system, it will rotate at a preset angle and move the designated material receiving station 4 to the material transfer nozzle 16 for subsequent material receiving operations.

[0029] The second automatic turntable 6 is also mounted on top of the first support platform 2. Its structure is similar to that of the first automatic turntable 3, but its function is different. A first cylinder 5 is mounted on the top of the second automatic turntable 6. This cylinder is fixed to the turntable surface by bolts and connected to an external air source via an air pipe. A material transfer nozzle 16 is mounted on the piston rod end of the first cylinder 5. The nozzle 16 adsorbs material using the negative pressure provided by a vacuum generator. The operating status of the vacuum generator is monitored in real time by the control system to ensure that the nozzle 16 maintains sufficient suction force when adsorbing material and quickly releases the negative pressure when releasing material. The rotation of the second automatic turntable 6 is synchronized with that of the first automatic turntable 3. When materials need to be transferred from the material transfer storage hole 14 on the slide plate 9 to the material receiving station 4, the second automatic turntable 6 will drive the first cylinder 5 and the material transfer nozzle 16 to move directly above the transfer storage hole 14. Then, the first cylinder 5 drives the nozzle 16 to move downward to absorb the materials. After the absorption is completed, the first cylinder 5 moves upward again. At the same time, the second automatic turntable 6 transfers the nozzle 16 to directly above the target material receiving station 4. Finally, the first cylinder 5 drives the nozzle 16 to move downward and release the materials, completing the material transfer process.

[0030] The sliding assembly consists of a slide rail 10 and a slide plate 9. The slide rail 10 adopts a sleeve structure, and the slide plate 9 cooperates with the slide rail 10 through a slider. That is, the interior of the slide rail 10 has a through-hole structure that matches the shape of the slide plate 9, allowing the slide plate 9 to reciprocate in a linear direction within the slide rail 10. A material transfer and storage hole 14 is machined on the slide plate 9. This hole is a stepped through-hole, wider at the top and narrower at the bottom. The upper end is designed with a trumpet-shaped structure to facilitate the smooth falling of materials, and the lower end connects to the material suction pipe 13 for securing the materials. The movement of the slide plate 9 is driven by a second cylinder 11, which is bolted to the second support platform 15. The piston rod end of the second cylinder 11 is connected to the slide plate 9. When the second cylinder 11 receives a command from the control system, it pushes the slide plate 9 to move along the slide rail 10, causing the material transfer and storage hole 14 to switch between the material pick-up position of the material transfer nozzle 16 and the position directly below the material drop channel 19 (i.e., the receiving position of the material transfer and storage hole 14). The sliding fit between the skateboard 9 and the slide rail 10 uses a material with a low coefficient of friction, and the motion resistance is further reduced through lubrication treatment, thereby improving the motion accuracy and response speed of the skateboard 9.

[0031] The material container 8 is installed above the feeding structure, and its bottom is provided with a discharge channel 19, which extends into the slide rail 10 and is aligned with the material transfer and storage hole 14. The material container 8 is equipped with a feeding mechanism, including a feeding motor 7 and a feeding plate 18. The feeding motor 7 is fixed to the top cover plate of the material container 8 by bolts, and its motor shaft passes through the cover plate and is connected to the feeding plate 18 via a coupling. The feeding plate 18 is located at the bottom of the material container 8 and can effectively feed material from inside the container to the discharge channel 19. When the material in the material container 8 is fed to the discharge channel 19 by the feeding plate 18, the material slides down the channel into the material transfer and storage hole 14 on the slide plate 9, completing the initial transfer of the material.

[0032] The mechanical limiting assembly 12 is mounted on the second support platform 15 and includes a base plate 122, a limiting rod 123, a spring 121, and a nut 124. The base plate 122 is fixed to the side of the second support platform 15 by bolts and has a guide hole machined on it parallel to the sliding path of the slide plate 9. The limiting rod 123 passes through and slides within the guide hole, with its front end facing the rear end of the slide plate 9. The spring 121 is sleeved on the limiting rod 123, with its two ends abutting against the nut 124 and the base plate 122, respectively. When the slide plate 9 moves along the slide rail 10, if it exceeds a predetermined range, the limiting rod 123 will apply a reverse force to the slide plate 9 under the action of the spring 121, thereby limiting the range of motion of the slide plate 9 and preventing overshoot. The length of the limiting rod 123 and the elastic coefficient of the spring 121 can be adjusted according to actual needs to adapt to different specifications of the slide plate 9 and slide rail 10 system.

[0033] In actual operation, the feeding structure of this utility model first uses a feeding motor 7 to drive a feeding plate 18 to push material 17 from the material container 8 to the dropping channel 19. The material 17 slides down the channel into the material transfer storage hole 14 on the sliding plate 9. Then, a second cylinder 11 drives the sliding plate 9 to move along the slide rail 10, moving the material transfer storage hole 14 to the material transfer suction nozzle 16's picking position. At this time, a first cylinder 5 drives the material transfer suction nozzle 16 downwards to absorb the material. After absorption, the first cylinder 5 moves upwards, while a second automatic turntable 6 moves the material transfer suction nozzle 16 directly above the target material receiving station 4. Finally, the first cylinder 5 drives the material transfer suction nozzle 16 downwards to release the material, completing the material transfer process. Throughout the feeding process, the Siemens 1200 controller precisely controls the actions of each component, ensuring the efficiency and reliability of the feeding process.

[0034] In summary, this utility model achieves continuous and stable material feeding, precise positioning and transfer, and efficient receiving functions through the coordinated operation of components such as the feeding mechanism, sliding assembly, automatic turntable, and material transfer nozzle. It is particularly suitable for automated training and teaching scenarios.
