Description

Technical Field

[0001] The utility model relates to the technical field of transportation equipment, in particular to a basket material trolley connected with an AGV. Background Art

[0002] In the field of piston casting production, after the as-cast piston is manufactured by a die casting machine, in order to ensure that the product quality meets the requirements of subsequent processing and application, it is necessary to detect internal defects through an X-ray equipment, which is a key link to guarantee the reliability of the performance of finished pistons. However, in actual production scenarios, there is often a large spatial distance between the working area of the die casting machine and the installation area of the X-ray testing equipment, which makes the transfer of as-cast pistons an important link in the production process. In the traditional mode, the transfer process mostly relies on manual handling: workers need to carry baskets of as-cast pistons from the die casting machine to a transfer tool (such as an ordinary trolley), and then push them to the X-ray equipment area for testing. This method not only consumes a lot of labor costs, but also has low manual handling efficiency, which is difficult to match the production rhythm of the die casting machine and the operation efficiency of X-ray testing, and easily causes problems such as material accumulation or material waiting in the testing link, which affects the smoothness of the overall production process. In order to improve the automation level of material transportation and reduce labor input, some production scenarios have begun to introduce AGVs (Automated Guided Vehicles) for the transfer of as-cast pistons. AGVs can automatically transfer material baskets filled with as-cast pistons from the die casting machine area to the transfer station close to the X-ray equipment according to preset paths. However, in the prior art, after the AGV completes material transfer, there is a lack of an efficient connection mechanism with the trolley: the material basket unloaded by the AGV usually needs to be temporarily stored on the ground or a fixed platform of the transfer station, and workers still need to manually move the material basket onto the trolley before pushing it to the X-ray equipment for testing. This process does not completely eliminate the manual handling link. In addition, due to the lack of an effective buffer structure, when the X-ray equipment is busy, the materials transferred by the AGV to the station cannot enter the testing link in time, which may cause the AGV to affect its material transfer efficiency to other areas due to waiting for unloading, thereby restricting the flow rhythm of the entire production line.

[0003] It can be seen that the prior art still needs to be improved and enhanced. Summary of the Utility Model

[0004] In view of the above deficiencies in the prior art, the object of the present utility model is to provide a basket material trolley connected with an AGV, aiming to realize rapid receiving and buffering of materials transferred by the AGV, reduce manual intervention, improve the material transfer efficiency from the die casting machine to the X-ray testing equipment, and ensure the continuity and stability of the production process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A basket material trolley that connects to an AGV includes two parking rails forming a transfer station, a trolley pushed between the two parking rails, basket materials that can be moved by the trolley or an AGV, a first sensing device for detecting whether the trolley is present at the transfer station, and a second sensing device for detecting whether the basket materials are present at the transfer station. The trolley includes a C-shaped frame consisting of a rear frame and two side frames, and casters located at the bottom of the C-shaped frame. A handle is provided at the back of the rear frame of the C-shaped frame, and a loading and unloading entrance / exit is formed at the front for the AGV to enter and exit. The tops of the two side frames of the C-shaped frame jointly support the basket materials and are provided with positioning components for positioning the basket materials.

[0006] As a further improvement to the above technical solution, both side frames of the C-shaped frame include a horizontally extending top square tube, vertical square tubes set at the bottom of both ends of the top square tube, and a reinforcing square tube set between the two vertical square tubes. An angle iron is provided on the inner side of the top square tube, and one plane of the angle iron is at the same height as the top surface of the top square tube.

[0007] As a further improvement to the above technical solution, the positioning component includes a front triangular block and a rear triangular block disposed on the top square tube and the angle iron, and a basket loading position is formed between the front triangular block and the rear triangular block. The end faces of the front triangular block and the rear triangular block facing each other form a first inclined surface that guides the basket material to slide toward the basket loading position.

[0008] As a further improvement to the above technical solution, the positioning component also includes a correction plate disposed on the outer side of the top square tube. The correction plate includes an inclined plate body and a vertical plate body bent at the bottom of the inclined plate body. The vertical plate body is fixedly connected to the outer side of the top square tube. A second inclined surface is formed on the inclined plate body to guide the basket material to slide towards the basket material loading position.

[0009] As a further improvement to the above technical solution, the correction plate also includes a narrowed plate body disposed at the front end of the inclined plate body.

[0010] As a further improvement to the above technical solution, a first reinforcing rib is provided at the inner corner of the splice between the inclined plate and the vertical plate.

[0011] As a further improvement to the above technical solution, the parking rail includes a ground frame, a straight channel steel set on the ground frame, a limiting channel steel set at the front end of the straight channel steel, and a narrowed channel steel set at the rear end of the straight channel steel. The straight channel steel is reinforcedly connected to the top surface of the ground frame by a second reinforcing rib.

[0012] As a further improvement to the above technical solution, the first sensing device is a limit switch installed on the straight channel steel, and the second sensing device includes a suspension beam and a photoelectric proximity sensor installed downward on the suspension beam. The first sensing device and the second sensing device are connected by a conduit, and the second reinforcing rib is provided with a C-shaped clamp for holding the conduit.

[0013] As a further improvement to the above technical solution, the basket includes a material-carrying basket and the material placed in the material-carrying basket. The material-carrying basket includes a rectangular base plate, a fence set on the edge of the base plate, and a handle set on the top of the fence.

[0014] Beneficial effects: Compared to existing technologies, the AGV-connected basket material trolley provided by this utility model reduces the manual transfer of basket materials from the AGV to the trolley in the traditional mode. Only a small amount of manpower is needed to push the trolley to the X-ray equipment at the end, significantly reducing labor costs compared to the previous method of entirely manual handling. The efficient connection between the AGV and the trolley allows for rapid transfer of basket materials, avoiding material accumulation caused by slow manual handling. This improves the material transfer efficiency from the die-casting machine to the X-ray inspection equipment, ensuring smooth production flow and a more compact production cycle. Furthermore, the detection by the first and second sensors ensures that the trolley and basket materials meet the transfer conditions, providing reliable assurance for the connection between the AGV and the trolley, reducing errors caused by improper connection, and improving the stability of the overall production process.

Detailed Implementation

[0021] This utility model provides a basket material trolley that connects to an AGV. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes the utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0022] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0023] Please see Figures 1 to 5This utility model provides a basket material handcart that connects with an AGV, including two parking rails 1 forming a transfer station, a handcart 2 pushed between the two parking rails 1, basket materials that can be transported by the handcart 2 or the AGV trolley 9, a first sensing device 4 for detecting whether the handcart 2 exists at the transfer station, and a second sensing device 5 for detecting whether the basket materials exist at the transfer station. The handcart 2 includes a chamfered frame 21 composed of a rear frame 211 and two side frames 212, and casters 22 set at the bottom of the chamfered frame 21. A handle 23 is provided on the back of the rear frame 211 of the chamfered frame 21, and a loading and unloading entrance 17 for the AGV trolley 9 to enter and exit is formed in front of it. The tops of the two side frames 212 of the chamfered frame 21 jointly support the basket materials and are provided with positioning components 7 for positioning the basket materials.

[0024] In the piston casting production process, when the AGV trolley, fully loaded with baskets of material, travels along a preset path to the transfer station, the first sensing device 4 first detects whether a handcart 2 is present at the transfer station. If the handcart 2 is detected as in place, the second sensing device 5 detects whether there are already baskets of material at the transfer station. If there is no space, the AGV trolley moves to the loading / unloading entrance / exit 17 in front of the handcart 2, and the AGV trolley 9 can transport the baskets it carries to the C-shaped frame 21 of the handcart 2. Since the C-shaped frame 21 consists of a rear frame 211 and two side frames 212, the top is used to support the baskets and is equipped with a positioning component 7. After the baskets reach the designated position, the positioning component 7 will position the baskets to ensure their stability during transportation. When there is an available inspection station for the X-ray equipment, the operator can push the handcart 2, whose casters 22 are located at the bottom of the C-shaped frame 21, using the handle 23 to transport the baskets to the X-ray equipment for inspection. Throughout the process, the various devices cooperated with each other to realize the material flow from the AGV cart 9 to the manual pushing to the testing equipment.

[0025] Compared with existing technologies, the AGV-connected basket material trolley 2 provided by this utility model reduces the step of manually transferring basket materials from the AGV to the trolley 2 in the traditional mode. Only a small amount of manpower is needed when pushing the trolley 2 to the X-ray equipment at the end. Compared with the previous manual handling throughout the entire process, it greatly reduces labor costs. The AGV trolley 9 and the trolley 2 achieve efficient connection, and the basket materials can be quickly transferred from the AGV to the trolley 2, avoiding material accumulation caused by slow manual handling, improving the material transfer efficiency from the die-casting machine to the X-ray inspection equipment, ensuring the smoothness of the production process, and making the production cycle more compact. In addition, through the detection of the first sensing device 4 and the second sensing device 5, it is ensured that the state of the trolley 2 and the basket materials meets the transfer conditions, providing a reliable guarantee for the connection between the AGV and the trolley 2, reducing errors caused by improper connection, and improving the stability of the overall production process.

[0026] Specifically, each of the two side frames 212 of the C-shaped frame 21 includes a horizontally extending top square tube 2311, vertical square tubes 2312 located at the bottom of both ends of the top square tube 2311, and a reinforcing square tube 2313 located between the two vertical square tubes 2312. The top square tube 2311, the vertical square tubes 2312, and the reinforcing square tube 2313 form a three-dimensional frame structure. The horizontally extending top square tube 2311 provides a horizontal support foundation for the whole, while the vertical square tubes 2312 at both ends transmit the force downward. The reinforcing square tube 2313 between the two vertical square tubes 2312 further enhances the deformation resistance of the side frame 212, enabling it to stably support the basket filled with piston casting raw materials, preventing the frame from bending or being damaged due to the large weight of the materials, and extending the service life of the equipment.

[0027] Furthermore, the inner side of the top square tube 2311 is provided with an angle iron 2314, and one plane of the angle iron 2314 is at the same height as the top surface of the top square tube 2311. The two form a continuous and flat support surface, which significantly increases the support area compared to a single top square tube 2311. This design makes the basket material more evenly stressed when placed, avoiding deformation or damage to the basket material due to excessive local stress. At the same time, it can more stably support basket materials of different specifications, improving the adaptability to various types of basket materials.

[0028] Specifically, the positioning component 7 includes a front triangular block 71 and a rear triangular block 72 set on the top square tube 2311 and the angle iron 2314. The front triangular block 71 and the rear triangular block 72 form a basket loading position 73. The structure of the triangular block is directional. When the AGV trolley 9 sends the basket into the loading position, the edge of the basket will automatically adjust its position along the inclined surface of the triangular block and finally stably lock into the front triangular block 71 and the rear triangular block 72, ensuring that the position of the basket on the frame is fixed and avoiding the basket from sliding back and forth due to the movement of the handcart 2 or the ground being bumpy. This fundamentally solves the problem of easy displacement of baskets in traditional handcarts 2.

[0029] To improve loading convenience, the facing end faces of the front triangular block 71 and the rear triangular block 72 form a first inclined surface 74 to guide the basket material to slide towards the basket material loading position 73. This provides a clearer and smoother guiding path for the basket material to enter the loading position. When the AGV trolley 9 pushes the basket material, even if there is a certain deviation between the initial position of the basket material and the loading position, after the edge of the basket material contacts the first inclined surface 74, it will automatically slide towards the center of the loading position under the guidance of the first inclined surface 74, completing the positioning without precise alignment. This significantly reduces the positional accuracy requirements when the AGV docks with the handcart 2, reduces loading failures or jams caused by alignment errors, and improves the fault tolerance of the entire loading and unloading process.

[0030] Furthermore, the positioning component 7 also includes a correction plate 75 disposed on the outer side of the top square tube 2311. The correction plate 75 includes an inclined plate body 751 and a vertical plate body 752 bent at the bottom of the inclined plate body 751. The vertical plate body 752 is fixedly connected to the outer side of the top square tube 2311. A second inclined surface 754 is formed on the inclined plate body 751 to guide the basket material to slide towards the basket material loading position 73. When the basket material deviates laterally during AGV pushing or manual placement, the side of the basket material will move towards the lateral center of the basket material loading position 73 under the guidance of the second inclined surface 754. This design works in conjunction with the front and rear triangular blocks 71 and 72 to provide front and rear positioning. The first inclined surface 74 addresses alignment deviations in the front-rear direction of the basket material, while the second inclined surface 754 specifically eliminates lateral deviations. Through their combined action, even if the initial placement of the basket material has multi-angle deviations, automatic correction can be achieved through the guidance of the inclined surfaces in two directions, eliminating the need for repeated manual adjustments. This solves the problem of inaccurate positioning caused by misaligned basket material, ensuring that the basket material is in the preset optimal bearing position. Furthermore, the correction plate 75 also includes a narrowing plate 753 located at the front end of the inclined plate body 751. Even if the lateral deviation of the basket material is large, the narrowing plate 753 can quickly reduce the deviation range through its gradually narrowing structure. This ensures that when the basket material contacts the second inclined surface 754, its lateral position is closer to the ideal state, reducing the guiding burden on the second inclined surface 754, lowering the requirements for AGV navigation accuracy and human operator proficiency, and making the docking process easier and more efficient.

[0031] From the perspective of structural strength improvement, the inner corner of the joint between the inclined plate 751 and the vertical plate 752 is the area where the stress on the straightening plate 75 is most concentrated. Therefore, a first reinforcing rib 755 is provided at the inner corner of the joint between the inclined plate 751 and the vertical plate 752. When the basket material comes into contact with the second inclined surface 754 and is subjected to lateral guiding force, this inner corner will bear the lateral torque from the inclined plate 751 and the supporting reaction force from the vertical plate 752. Long-term stress can easily lead to weld cracking or plate deformation. The first reinforcing rib 755 fills the inner corner space with a triangular stabilizing structure, dispersing the local stress to a larger contact area, significantly improving the flexural strength and torsional stiffness of the joint.

[0032] In this embodiment, the parking rail 1 includes a base frame 11, a straight channel steel 12 mounted on the base frame 11, a limiting channel steel 13 positioned at the front end of the straight channel steel 12, and a narrowing channel steel 14 positioned at the rear end of the straight channel steel 12. The straight channel steel 12 is reinforcedly connected to the top surface of the base frame 11 by a second reinforcing rib 15. The straight channel steel 12 provides a linear guiding reference for the handcart 2, ensuring its smooth movement along a preset path. The limiting channel steel 13 at the front end serves as a terminal positioning element. When the handcart 2 travels along the straight channel steel 12 to the front end, the limiting channel steel 13 precisely limits its forward distance, avoiding overshoot due to inertia or control errors, and ensuring that the handcart 2 stops at the preset endpoint position. The gradually narrowing structure of the narrowing channel steel 14 at the rear end can correct the path of the handcart 2 entering from the rear. Even if there is a slight deviation in the initial travel direction of the equipment, it can gradually return to the track route of the straight channel steel 12 under the guidance of the narrowing channel steel 14, significantly improving the parking positioning accuracy.

[0033] In this embodiment, the first sensing device 4 is a limit switch mounted on the straight channel steel 12. It is precisely triggered when the trolley 2 aligns with the limiting channel steel 13, sending a feedback signal to the control system. The second sensing device 5 includes a suspension beam and a photoelectric proximity sensor mounted downwards on the suspension beam. The photoelectric proximity sensor can accurately sense the presence of the basket material. When the trolley 2 stops, the sensor can quickly provide feedback on the presence or absence of the basket material, providing crucial data support for subsequent automated processes (such as scheduling handling equipment and recording material information). The first sensing device 4 and the second sensing device 5 are connected by a cable tray 8. The second reinforcing rib 15 is provided with a C-shaped clamp 16 for holding the cable tray 8. The cable tray 8 effectively protects and stores the cables of the first sensing device 4 and the second sensing device 5. The cables are encased in the cable tray 8, which isolates them from external dust, moisture, and mechanical friction, reducing the risk of short circuits, open circuits, and other faults caused by cable damage, and extending the service life of the sensing devices. Meanwhile, the C-shaped clamp on the second reinforcing rib 15 can firmly clamp the cable conduit 8, preventing the cable conduit 8 from loosening or falling off due to vibration and collision when the handcart 2 passes by. This avoids interference to the working environment caused by scattered cables, reduces the risk of cables being crushed or pulled, and ensures the stability of the circuit connection.

[0034] The basket includes a material carrier basket 3 and the material placed inside it. The material carrier basket 3 includes a rectangular base plate 31, a fence 32 set on the edge of the base plate 31, and a handle 33 set on the top of the fence 32. The standardized dimensions of the rectangular base plate 31 can be precisely connected to equipment such as handcarts 2, conveyor belts, and AGV carts 9 on the production line. The openwork or low design of the fence 32 (adjusted according to the height of the raw material) will not obstruct X-ray inspection.

[0035] When operators move the material using handle 33, they can apply force evenly, avoiding tilting of the basket due to unstable grip, and preventing personal injury or material loss caused by the slipping of raw materials.
