Description

Technical Field

[0001] This utility model relates to the field of workpiece conveying technology, and in particular to a three-dimensional feeding device. Background Technology

[0002] In many fields such as industrial production and logistics, the handling and storage of various workpieces has always been a crucial step. Currently, many workpieces are typically carried on pallets. As a commonly used carrying tool, pallets can centrally organize scattered workpieces, facilitating handling, storage, and transportation, thus improving work efficiency and operational convenience. They are widely used in various production scenarios; for example, in machining workshops, finished parts are placed on pallets; and in warehouse logistics, pallets are frequently used to stack goods to fully utilize space.

[0003] However, existing technologies have significant shortcomings in pallet stacking operations. Currently, most pallets carrying workpieces are manually stacked on workbenches. Because the workbenches are at a certain height, operators need to constantly bend and straighten during the stacking process, performing repetitive movements. Moreover, the workpieces are often quite heavy, and prolonged operation puts a significant strain on the operator's body, leading to discomfort. Operators working in this state for extended periods are prone to occupational diseases affecting the lower back and neck. Furthermore, when handling heavy workpieces, operators are prone to dropping them due to fatigue and distraction, resulting in breakage. This not only damages the workpieces and increases production costs but may also disrupt the entire production process and reduce efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a three-dimensional feeding device to solve the problems in the prior art, such as the impact on the health of operators when manually stacking pallets due to the height of the workbench, and the easy for operators to drop their hands and damage the workpieces.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] In current technology, pallets are mostly stacked manually on workbenches. Because the workbenches are relatively high, operators need to constantly bend and straighten during the stacking process, performing repetitive movements. Moreover, the workpieces are often quite heavy, and prolonged operation like this places a significant strain on the operator's body, leading to discomfort. Operators working in this state for extended periods are prone to occupational diseases affecting the lower back and neck. Furthermore, when handling heavy workpieces, operators are prone to dropping them due to fatigue and distraction, resulting in breakage. This not only damages the workpieces and increases production costs but may also disrupt the entire production process and reduce efficiency.

[0037] To address the aforementioned problems, this embodiment provides a three-dimensional feeding device, see reference. Figures 1-3 The three-dimensional feeding device includes a workbench 10, a first conveying mechanism 20, a second conveying mechanism 30, and a transfer mechanism 40.

[0038] Furthermore, the workbench 10 includes a first station and a second station spaced apart along a first direction. The workbench 10 has clearance holes that correspond to the positions of the first stations. A first conveying mechanism 20 is spaced apart below the workbench 10. The first conveying mechanism 20 includes a first conveying component 21, which can convey the pallet 1 along the first direction. A second conveying mechanism 30 is located below the workbench 10. The second conveying mechanism 30 includes a second conveying component and a support member 32. The second conveying component can vertically convey the support member 32. The support member 32 is located around the periphery of the first conveying component 21 and corresponds to the position of the clearance holes to support the pallet 1 and convey the pallet 1 to the first station. A transfer mechanism 40 includes a transfer member 41, which is movably disposed between the first station and the second station to transfer the pallet 1. The operator places the pallet 1 on the first conveyor 20, which is at a lower height. The pallet 1 is then conveyed by the first conveyor 20 and the second conveyor 30 to the first workstation on the workbench. The pallet 1 is then moved from the first workstation to the second workstation by the transfer mechanism 40, thus realizing the three-dimensional transport of the pallet 1. This reduces the labor intensity of the operator and the chance of accidentally damaging the workpiece.

[0039] It should be noted that both the first and second workstations can selectively set the processing flow. When the first workstation sets the processing flow, the support member 32 remains in the position of the clearance hole to support the pallet 1. After the pallet 1 is moved by the conveying mechanism 40, the support member 32 can return to its original position to move the next pallet 1.

[0040] Furthermore, the first conveying mechanism 20 also includes a first support base 22 and a second support base 23, which are spaced apart along a second direction. The first conveying assembly 21 includes a conveyor belt 211 and a conveyor shaft 212. The conveyor shaft 212 is rotatably disposed on the side of the first support base 22 and / or the second support base 23 that are close to each other. The conveyor belt 211 is wound around the conveyor shaft 212 and driven by the conveyor shaft 212 to convey the pallet 1. In this embodiment, there are two conveyor belts 211 and four conveyor shafts 212 disposed on the opposite side of the first support base 22 and the second support base 23. In other embodiments, there may be one conveyor belt 211. In other embodiments, a conveyor chain may be used to convey the pallet 1. It should be noted that the conveyor belt 211 is a toothed conveyor belt, and the conveyor shaft 212 is provided with a corresponding toothed structure to prevent the conveyor belt 211 from slipping.

[0041] Specifically, the first conveying assembly 21 further includes a first driving member 213, which is connected to the conveying shaft 212 to drive the conveying shaft 212 to rotate. Specifically, the first driving member 213 is configured as a rotary motor. In this embodiment, the first conveying assembly 21 also includes a coupling 214 to connect two active conveying shafts 212 at corresponding positions, enabling the two active conveying shafts 212 to rotate synchronously.

[0042] Furthermore, the first conveying mechanism 20 also includes multiple first limiting members 24, which are disposed on the top of the first support 22 and the second support 23 to restrict the pallet 1 from detaching from the conveyor belt 211 in the second direction. Specifically, the first limiting member 24 is configured as a limiting plate, which is located on both sides of the two conveyor belts 211 to restrict the position of the pallet 1 in the second direction. In other embodiments, the first limiting member 24 may be configured as multiple limiting rods spaced apart along the first direction.

[0043] Furthermore, the support member 32 is a support plate. When the conveyor belt 211 connects with the support plate to the pallet 1, the bearing surface of the support plate is lower than the bearing surface of the conveyor belt 211. In this embodiment, the support plate is located between the two conveyor belts 211. When the pallet 1 moves to the position of the support plate, the support plate moves upward and carries the pallet 1 away. In other embodiments, the support plate can be located at the output end of the two conveyor belts 211, and the pallet 1 slides naturally onto the support plate under the conveying of the conveyor belts 211.

[0044] Furthermore, the second conveying assembly includes a first slide rail 31, and the support member 32 includes a first slider 321. The first slide rail 31 extends vertically, and the first slider 321 slides in cooperation with the first slide rail 31. Specifically, the second conveying assembly also includes a support column 33 and a second driving member 34. The support column 33 extends vertically, the first slide rail 31 is disposed on the support column 33, and the second driving member 34 is a linear motor to drive the first slider 321 to move.

[0045] Furthermore, the second conveying assembly also includes a reinforcing member 35, which is a triangle formed by splicing rods. The reinforcing member 35 is disposed between the bottom of the support member 32 and the first slider 321 to distribute the force on the support member 32 and increase the strength of the support member 32.

[0046] Furthermore, the conveying mechanism 40 also includes a second slide rail 42 and a transfer assembly 43. The second slide rail 42 is located on the periphery of the worktable 10 and extends along a second direction. The transfer assembly 43 includes a second slider 431, which slides in cooperation with the second slide rail 42. The conveying component 41 is connected to the transfer assembly 43. Specifically, the conveying mechanism 40 also includes a supporting column 44, which extends along a first direction. The second slide rail 42 is located on the supporting column 44. In other embodiments, the conveying component 41 can be moved by a screw and nut or by a sliding roller.

[0047] Specifically, the adapter assembly 43 includes a connecting block 432 and an electric push rod 433. The electric push rod 433 is fixed to the second slider 431 and driven in a vertical direction. The conveying component 41 is fixed to the connecting block 432, and the connecting block 432 is fixed to the driving end of the electric push rod 433, so as to drive the conveying component 41 to move in a vertical direction. In this embodiment, a suction nozzle 411 is provided on the side of the conveying component 41 near the tray 1, and multiple suction nozzles 411 are arranged in an array. By moving the conveying component 41 in a vertical direction, the suction nozzles 411 abut against or disengage from the tray 1. Specifically, the suction nozzles 411 are connected to a vacuum component. It should be noted that the vacuum component is prior art and will not be described in detail here.

[0048] In this embodiment, the conveying component 41 is a conveying plate, and the conveying plate has multiple weight-reducing holes 412. The multiple weight-reducing holes 412 are provided to reduce the weight of the conveying plate, thereby reducing the load on the electric push rod 433 and increasing the service life of the electric push rod 433.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
