[0056] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0057] The present application provides a feeding device and a material box robot. Figures 1 to 12 A schematic diagram of the structure of a feeding device provided in an embodiment of the present application.

[0058] See also Figures 1 to 3 The feeding device 100 includes a bracket 1, a driving mechanism 2 and a guide structure 3.

[0059] The bracket 1 serves as the basic structure of the entire device, providing support and stability, ensuring that all components can be properly installed and maintaining structural integrity. It is usually made of high-strength materials, such as steel or alloy, to withstand the load and stress of the device during operation.

[0060] The driving mechanism 2 includes a driving wheel 21, a driven wheel 22 and a transmission member 23 (see the attached Figure 7), the driving wheel 21 and the driven wheel 22 are installed on the bracket 1 at intervals, and the transmission member 23 is sleeved on the periphery of the driving wheel 21 and the driven wheel 22, so that the driving wheel 21 can drive the transmission member 23 to rotate, and an installation space is formed on the inner peripheral side of the transmission member 23, wherein the driving wheel 21 is driven by a driving device, and the driven wheel 22 is used in conjunction with the driving wheel 21 to jointly support and guide the transmission member 23. The transmission member 23 can be a chain, a belt or a wire rope, etc., which is surrounded between the outer peripheral edges of the driving wheel 21 and the driven wheel 22 that are away from each other. When the driving wheel 21 rotates, it will rotate accordingly, thereby realizing a lifting action. An installation space is formed on the inner peripheral side of the transmission member 23 for accommodating the guide structure 3 or other necessary structural members (such as the driving wheel 21 and the driven wheel 22).

[0061] The guide structure 3 is installed on the bracket 1. The guide structure 3 is used to be slidably connected with the bearing structure 5. The guide structure 3 can be a guide rail or a guide column, which is used to guide the bearing structure 5 to move along a predetermined path (for example, it can be a vertical direction) to ensure the smoothness and accuracy of the movement. The guide structure 3 is at least partially located in the installation space to make the structure compact and save space. The main function of the bearing structure 5 is to carry and fix the material to be transported. The bearing structure 5 can be a platform, a hopper or other forms of loading containers.

[0062] In the technical solution of the present application, the main purpose of the guide structure 3 is to ensure that the bearing structure 5 maintains linear motion along a preset path (for example, it can be a vertical direction) to prevent it from deviating from the track. The guide structure 3 can enable the bearing structure 5 to accurately reach the set point, so that the material can accurately reach a certain position and accurately control the movement position of the material. The guide structure 3 limits the degree of freedom of the bearing structure 5, reduces lateral swing and vibration, and improves the stability and safety of the entire system. The guide structure 3 is built into the installation space of the transmission member 23, which can significantly reduce the lateral size of the entire device, making the equipment more compact and saving space. Moreover, the guide structure 3 is located inside the transmission member 23, which also has a certain effect of reducing external interference and reducing the risk of accidental damage. That is, this solution provides guidance for the movement of the bearing structure 5 through the sliding connection between the guide structure 3 and the bearing structure 5, thereby improving the accuracy and stability of the operation. On this basis, by arranging at least part of the guide structure 3 in the installation space, the structure is made more compact and has the advantage of small space.

[0063] In the related art, the columns in the bracket 1 are usually made of large-scale one-piece open mold profiles, such as aluminum profiles, which are relatively expensive.

[0064] In some embodiments, see Figures 9 to 11The bracket 1 includes a column assembly 11, and the column assembly 11 includes a first sheet metal part 111 and a second sheet metal part 112. The second sheet metal part 112 is connected to the first sheet metal part 111 to define a mounting cavity 115 between the second sheet metal part 112 and the first sheet metal part 111; wherein the guide structure 3 is mounted on a side of the second sheet metal part 112 away from the mounting cavity 115, and the transmission member 23 is disposed in the mounting cavity 115 (see Figure 7 and Figure 8 ). In these embodiments, the first sheet metal part 111 and the second sheet metal part 112 can be manufactured by stamping, bending and other processes. Compared with large-scale integrated mold parts, the production cost of sheet metal parts is lower, and the mold cost is relatively less. The combined installation method reduces the difficulty of production and manufacturing. Through the combination of the first sheet metal part 111 and the second sheet metal part 112, not only a stable support structure is formed, but also the guide structure 3 is installed on the outer side of the second sheet metal part 112. The guide structure 3 is easy to install. The first sheet metal part 111 and the second sheet metal part 112 form an installation cavity 115 inside for the transmission part 23 to pass through. The structure is compact and space-saving. In addition, the manufacturing process of sheet metal parts has greater freedom in size, shape and structure, and can be customized according to specific application requirements, such as adding reinforcing ribs, reserving mounting holes, etc., without the need to remake the mold. Specifically, the column assembly 11 also includes a third sheet metal part 113 and a fourth sheet metal part 114. The third sheet metal part 113 is connected to one end of the first sheet metal part 111 and the second sheet metal part 112 to serve as the top mounting structure of the column assembly 11. The third sheet metal part 113 is provided with a through hole 1131, and the through hole 1131 is for the transmission part 23 to pass through. The fourth sheet metal part 114 is connected to the first sheet metal part 111 and the third sheet metal part 113 to play a reinforcing role.

[0065] It can be understood that the bearing structure 5 has extreme positions in the direction of movement (for example, the bearing structure 5 moves in the vertical direction and has a lowest position and a highest position). Figure 1 , Figure 2 and Figure 6 The feeding device 100 further includes a buffer 6, which is arranged at one end of the bearing structure 5 in the direction of movement, and provides buffering for the bearing structure 5 to move to the extreme position in the direction of movement. In these embodiments, the buffer 6 provides buffering force for the bearing structure 5 to move to the extreme position in the direction of movement, prevents hard collision, reduces the impact of movement on the structure, protects the structure, especially the impact on the transmission member 23, reduces its wear and tear, reduces the overall shaking caused by the impact, improves stability, and reduces noise.

[0066] The present application does not limit the type of the buffer 6, which may be a hydraulic buffer 6, a pneumatic buffer 6, a spring buffer 6, etc. Specifically, in some embodiments, the buffer 6 is an oil pressure buffer 6, which is beneficial to control costs.

[0067] For some examples, see Figure 2 and Figure 6 , the bearing structure 5 moves in the vertical direction, and the feeding device 100 also includes an upper limit structure 12 and a lower limit structure 13, wherein the upper limit structure is arranged at the upper end of the guide structure 3, and the lower limit structure 13 is arranged at the lower end of the guide structure 3, wherein the sliding structure 4 is arranged between the upper limit structure 12 and the lower limit structure 13, so that even if the bearing structure 5 continues to rise out of control during the lifting process, the sliding structure 4 will contact the upper limit structure 12 to prevent the sliding structure 4 from further moving upward, and even if the control system fails completely, it can prevent the bearing structure 5 from excessively rising and avoid a hard collision with the upper structure, thereby protecting the equipment structure, and the lower limit structure 13 also plays a role of physical limiting, preventing the bearing structure 5 from continuing to move downward out of control during the descent process, and avoiding the bearing structure 5 from hitting the structure below due to loss of control, thereby reducing the risk of equipment damage and ensuring the safety of the operator. Specifically, these limit structures are usually made of high-strength materials, such as steel or hardened alloys, to ensure sufficient hardness and durability.

[0068] For some examples, see Figure 1 , Figure 2 and Figure 6 The feeding device 100 further includes a lubricant adding device 7, which is disposed above the transmission member 23 in the vertical direction so that the transmission member 23 receives the lubricant dripping from the lubricant adding device 7. In these embodiments, the lubricant can reduce the friction between the transmission member 23 (chain, belt or wire rope) and its contact parts, thereby reducing wear and extending the service life of the transmission member 23. It can also reduce the friction resistance between moving parts, making the movement of the transmission member 23 smoother and improving efficiency. The lubricant adding device 7 is disposed above the transmission member 23 so that the transmission member 23 receives the lubricant dripping from the lubricant adding device 7, which can facilitate the addition of lubricant, is conducive to automating the lubricant adding device 7, reducing the frequency and workload of manual lubrication, simplifying the maintenance process, and reducing maintenance costs.

[0069] In the related art, in order to make the feeding device 100 have a buffering function, a cache structure is set up, and the cache structure includes multiple cache trays 9. Usually, cache shelves and supporting columns are additionally provided to support the cache trays 9. Therefore, the structure is complex and occupies space.

[0070] In some embodiments, see Figure 1 and Figure 2The feeding device 100 further includes a cache structure and a fork (not shown in the figure). The cache structure includes a plurality of cache trays 9. The plurality of cache trays 9 are mounted on the bracket 1 and are arranged in sequence in the direction of movement of the bearing structure 5. The fork is mounted on the bearing structure 5, and the fork is used to transfer the material on the bearing structure 5 to the cache tray 9. In these embodiments, the cache tray 9 is directly mounted on the bracket 1 of the feeding device 100 instead of using a separate cache shelf, which eliminates the space requirement of the independent cache shelf and its supporting columns, making the entire device more compact, improving space utilization, and having a simpler structure and lower cost. The fork is mounted on the bearing structure 5 and can move vertically with the bearing structure 5, and the fork can transfer the material on the bearing structure 5 to the cache tray 9, thereby realizing the transfer of materials between the bearing structure 5 and the cache tray 9.

[0071] In some embodiments, Figure 1 and Figure 2 As shown, the load-bearing structure 5 can move to dock with different buffer trays 9, so that the fork can push the materials in the load-bearing structure 5 to the buffer tray 9 docked with the load-bearing structure 5. In these embodiments, when the load-bearing structure 5 moves to dock with a certain buffer tray 9, the fork can push the materials on the load-bearing structure 5 to the buffer tray 9, thereby improving the speed and accuracy of material handling.

[0072] In some embodiments, see Figure 1 and Figure 5 The feeding device 100 also includes a wire trough 14 and a drag chain 15. In this way, when an object or device that needs to be electrically driven is installed on the bearing structure 5, the wire harness for transmitting signals and power can extend from the bottom to the top of the drag chain 15 through the wire trough 14, and then from the top through the inside of the drag chain 15 to the bottom of the drag chain 15, so that the wire harness reaches the bearing structure 5. The top of the drag chain 15 is connected to the bearing structure 5. When the bearing structure 5 rises ( Figure 1 In the embodiment, the bearing structure 5 is in the lowest position, Figure 5 In the embodiment, the supporting structure 5 is at the highest position), the drag chain 15 will be driven so that the top of the drag chain 15 remains in a fixed relative position with the supporting structure 5, so that the wiring harness can move with the supporting structure 5 within a fixed range.

[0073] It is understandable that when the buffer tray 9 is in a dynamic state (such as acceleration or deceleration), the material on the buffer tray 9 may slide or fall due to inertia. Figure 2The buffer tray 9 has a first end 91 close to the bearing structure 5 and a second end 92 away from the bearing structure 5. The first end 91 of the buffer tray 9 is used to dock with the bearing structure 5. The buffer tray 9 has an upward bearing surface, and the bearing surface is tilted downward in the direction from the first end 91 of the buffer tray 9 to the second end 92 of the buffer tray 9. In these embodiments, by reasonably designing the tilt angle of the bearing surface, a greater friction force is provided when the buffer tray 9 is in a dynamic state (such as acceleration, deceleration or turning), thereby enhancing the stability of the material, preventing it from accidentally sliding out or falling, and improving safety.

[0074] In some embodiments, Figure 2 As shown, the second end 92 of the buffer tray 9 extends upwardly with a first rib 93. In these embodiments, the first rib 93 can effectively prevent the material from sliding off the second end 92 of the buffer tray 9, especially when the buffer tray 9 is designed to be inclined, the rib can ensure that the material will not accidentally fall due to gravity, thereby increasing the safety of material storage, and the rib can also serve as a reference for material positioning, helping the material to accurately dock at a predetermined position.

[0075] In some embodiments, Figure 2 As shown, the first side rib 93 has two ends in the horizontal direction, and at least one end of the first side rib 93 extends a second side rib 94 toward the first end 91 of the buffer tray 9. In these embodiments, the first side rib 93 not only forms a boundary at the second end 92 of the buffer tray 9, but also further extends at one or both ends thereof, and adds an additional side rib, i.e., the second side rib 94, toward the first end 91 of the buffer tray 9. The addition of the second side rib 94 can further limit the movement of the material on the buffer tray 9, especially when the buffer tray 9 is in a dynamic state (such as accelerating, decelerating or turning), it can reduce the risk of the material sliding due to inertia.

[0076] In some embodiments, Fig.12 As shown, at least one mounting plate 95 is provided on the side of the cache tray 9 facing away from the bearing surface, and a mounting hole 951 is provided on the mounting plate 95, and the mounting hole 951 is used to pass fasteners so that the cache tray 9 is fixedly mounted on the bracket 1. In these embodiments, a mounting hole 951 is provided on the mounting plate 95, and the mounting hole 951 is used to pass fasteners (such as screws, bolts, etc.), and the fasteners pass through the mounting hole 951 and fix the cache tray 9 on the bracket 1, which can ensure the stability and reliability of the cache tray 9 under various working conditions. This design allows the cache tray 9 to be easily installed on the bracket 1, and through the fixation of the fasteners, it is ensured that the cache tray 9 will not loosen or fall off during use, thereby enhancing the structural stability of the entire feeding device 100. At the same time, this installation method is also convenient for maintaining and replacing the cache tray 9, and improves the maintainability and flexibility of the equipment.

[0077] In some embodiments, such as Figure 1 and Figure 2 As shown, the bracket 1 includes two column assemblies 11 and a crossbeam 16. The two column assemblies 11 are arranged at intervals, the crossbeam 16 connects the two column assemblies 11, and the cache tray 9 is connected to the crossbeam 16. In these embodiments, the two column assemblies 11 are arranged at intervals, and the crossbeam 16 connects the two column assemblies 11 to form a stable support structure. By fixing the cache tray 9 on the crossbeam 16 and using the two column assemblies 11 as support, the entire system becomes very stable and can effectively support weight and resist vibration during work. Specifically, the crossbeam 16 is provided with fastening holes, and the fasteners are provided with mounting holes 951 and fastening holes to fix the cache tray 9 and the bracket 1. The crossbeam 16 is provided with fastening holes, and the positions and sizes of these holes are designed to match the mounting holes 951. By passing the fasteners (such as screws or bolts) through the mounting holes 951 on the mounting plate 95 of the cache tray 9 and the fastening holes on the crossbeam 16, the cache tray 9 and the crossbeam 16 are connected, which is easy to assemble and disassemble, and convenient for maintenance and transportation.

[0078] In some embodiments, such as Fig.12 As shown, at least one reinforcing plate 96 is provided on the side of the cache tray 9 facing away from the bearing surface, and one end of the reinforcing plate 96 is connected to one side of the mounting plate 95 in the thickness direction. In these embodiments, by adding the reinforcing plate 96 on one side of the mounting plate 95, one end of the reinforcing plate 96 is connected to one side of the mounting plate 95 in the thickness direction, which means that the reinforcing plate 96 is connected to the mounting plate 95 to form a spatial structure, which improves the overall rigidity and strength of the cache tray 9, can better disperse the load, reduce the deformation of the cache tray 9 when it bears weight or is impacted, and ensure that the cache tray 9 can maintain good performance under various working conditions.

[0079] In some embodiments, Figure 3As shown, the sliding structure 4 includes a main body 41 and a connecting part 42. The main body 41 is slidably mounted on the guide structure 3. The connecting part 42 is connected to the main body 41. The two free ends of the transmission member 23 are respectively connected to the two ends of the connecting part 42 along the vertical direction. In these embodiments, the transmission member 23 serves as the main transmission element, and its two ends are respectively connected to the two ends of the sliding structure 4 to form a closed loop. When the power source of the driving mechanism 2 is started, the driving wheel 21 is driven to rotate, driving the transmission member 23 to rotate accordingly. Since both ends of the transmission member 23 are connected to the sliding structure 4, when the transmission member 23 rotates, it will drive the sliding structure 4 to move as a whole. This closed-loop driving mechanism 2 can effectively prevent the sliding structure 4 from being deflected during the movement because the two ends are subjected to uniform force, and has better balance, thereby ensuring the smoothness and safety of material transportation. Even if the friction or resistance on one side changes, the overall stability can be maintained through compensation on the other side. It can self-regulate to a certain extent and has enhanced stability. That is, the two ends of the transmission member 23 are respectively connected to the two ends of the sliding structure 4 to form a closed-loop structure, which can provide a more stable lifting force and ensure the balance of the sliding structure 4 during the movement, thereby avoiding the tilt or shaking that may be caused by unilateral drive.

[0080] In some embodiments, Figure 3 As shown, the main body 41 and the connecting part 42 are separately arranged and detachably connected. The separate design of the sliding structure 4 makes maintenance and replacement easier. The connecting part 42 can be removed without disassembling the entire system (such as Figure 4 As shown), in order to adjust or replace related components (such as the tensioning guide rod 25 and the tensioning elastic member 26, etc.).

[0081] In some embodiments, Figure 4 As shown, the connecting portion 42 is provided with at least one guide hole, the driving mechanism 2 further includes a tensioning guide rod 25 and a tensioning elastic member 26, at least one end of the transmission member 23 is connected with the tensioning guide rod 25, the tensioning guide rod 25 is movably arranged in the guide hole, the tensioning elastic member 26 is arranged between the sliding structure 4 and the tensioning guide rod 25, and the tensioning elastic member 26 is used to drive the tensioning guide rod 25 to apply tensioning force to the transmission member 23. In these embodiments, the tensioning guide rod 25 is driven by the tensioning elastic member 26 to apply tensioning force to the transmission member 23, so as to keep the transmission member 23 in a tensioned state, the tensioning guide rod 25 is movably arranged in the guide hole, and through the guidance of the guide hole, the tensioning guide rod 25 can apply tensioning force more accurately, ensure that the transmission member 23 maintains a good tensioning state, reduce vibration and noise during operation, and improve the operation stability of the equipment and the accuracy of material handling. Specifically, the tensioning elastic member 26 can be a spring or other elastic member.

[0082] In some embodiments, Figure 4As shown, a bushing 10 is provided in the guide hole, and the tensioning guide rod 25 is passed through the bushing 10. It can be understood that the bushing 10 can significantly reduce the direct contact between the tensioning guide rod 25 and the sliding structure 4, reduce the wear rate, and the existence of the bushing 10 makes the tensioning guide rod 25 smoother when sliding. The coordinated use of the guide hole and the bushing 10 ensures the straightness of the tensioning guide rod 25 during movement, avoids deflection and shaking, helps to maintain the uniform tension of the transmission member 23, and improves the stability and accuracy of the equipment operation. Specifically, the bushing 10 is usually made of wear-resistant material, and grease can also be added to the bushing 10 to achieve a better lubrication effect.

[0083] In some embodiments, the transmission member 23 includes a transmission belt or a transmission chain. Whether it is a transmission belt or a transmission chain, the length can be adjusted as needed to adapt to different mechanical layouts. Both designs are relatively simple, easy to manufacture and install, and help reduce costs.
