The fourth driving component drives the transfer component to descend to pass through the unloading and transporting assembly, so that it can place the pallet on the unloading and transporting assembly.

[0015] The transportation device provided in this application takes a pallet loaded with workpieces as an example. The frame serves as the structural support frame of the transportation device, providing installation positions and structural stability for the various components of the transportation device. The pallet is placed on the loading and transportation component, which can carry the pallet to dock with the loading and unloading component. After the loading and unloading component picks up the pallet from the loading and transportation component, the transfer component can move along the first direction to below the loading and unloading component, so that the loading and unloading component can place the pallet on the transfer component.

[0016] Then, the transfer component moves along the first direction to leave the material handling station below the loading and unloading component, and can move to the workpiece unloading station to complete the unloading. It can then move to the unloading and unloading component, which can then pick up the empty pallet carried by the transfer component. At the same time, the loading and transport component can continue to carry the next pallet containing the workpiece to dock with the loading and unloading component, which will then pick up the pallet from the loading and transport component.

[0017] Then the material transfer component can move again along the first direction to below the material loading and unloading component, so that the material loading and unloading component can place the currently picked-up pallet on the material transfer component.

[0018] In this process, the pallet containing the workpiece is moved above the unloading and transporting component. After the workpiece is removed, the remaining empty pallet is moved away from the unloading and transporting component. In other words, the flow path of the pallet on the transport device of this application can be understood as being set from top to bottom, which helps to reduce the floor space occupied.

[0019] Furthermore, both the material transfer component and the unloading and transport component are transported along the first direction, which can further optimize the structural footprint. At the same time, the loading station for pallets containing workpieces and the unloading station for empty pallets can be set at the same end of the transport device near the first direction. This facilitates loading pallets containing workpieces and unloading empty pallets on the same side of the transport device, which helps to improve the efficiency of loading and unloading.

[0034] Please see Figure 1 and Figure 7 The transport device 10 provided in this application embodiment will now be described. The transport device 10 provided in this application embodiment includes a frame 11, a loading transport component 12, a loading and unloading component 13, a transferring component 14, an unloading transport component 15, and an unloading and unloading component 16. The loading transport component 12 is transportably mounted on the frame 11 and is used to transport a pallet 30 containing workpieces. The loading and unloading component 13 is mounted on the frame 11 and located above the loading transport component 12. The loading and unloading component 13 and the loading transport component 12 are movably mounted relative to each other in the vertical direction (denoted as Z) so that the loading and unloading component 13 can pick up the pallet 30 carried by the loading transport component 12. The transferring component 14 is mounted above the loading transport component 12 and located below the loading and unloading component 13. The transferring component 14 is movably mounted on the frame 11 in a first direction. One direction is parallel to the horizontal plane, denoted as X; the material transfer component 14 moves along the first direction to below the loading and unloading component 13, receives the tray 30 placed by the loading and unloading component 13, and then moves along the first direction away from the material transfer component 14 to the workpiece unloading position; the unloading transport component 15 is transportably disposed on the frame 11 along the first direction and is located below the loading and transport component 12; the unloading and unloading component 16 is disposed on the frame 11 and is located above the material transfer component 14, and the unloading and unloading component 16 and the loading and unloading component 13 are spaced apart along the first direction; when the material transfer component 14 is located at the workpiece unloading position, the unloading and unloading component 16 can pick up the tray 30 carried by the material transfer component 14, and after the material transfer component 14 moves away from the workpiece unloading position, the unloading and unloading component 16 can place the tray 30 on the unloading transport component 15.

[0035] The transport device 10 provided in this application embodiment takes a pallet 30 containing workpieces as an example. The pallet 30 is always placed horizontally during circulation. The type of workpiece is not limited, as long as it meets the transport requirements of the transport device 10 of this application. During the use of the transport device 10, the pallet 30 is placed on the loading and transporting component 12. The loading and transporting component 12 can carry the pallet 30 to dock with the loading and picking component 13. After the loading and picking component 13 picks up the pallet 30 from the loading and transporting component 12, the transferring component 14 can move along the first direction to below the loading and picking component 13, so that the loading and picking component 13 can place the pallet 30 on the transferring component 14.

[0036] Then, the transfer component 14, carrying the pallet 30, moves along the first direction to leave the material handling station below the loading and unloading component 13, and can move to the workpiece unloading station to complete the unloading. Then, it can move to the unloading and unloading component 16, which can pick up the empty pallet 30 carried by the transfer component 14 at this time. At the same time, the loading and transport component 12 can continue to carry the next pallet 30 with the workpiece until it docks with the loading and unloading component 13, and the loading and unloading component 13 continues to pick up the pallet 30 from the loading and transport component 12.

[0037] Then the material transfer component 14 can move again along the first direction to below the material loading and unloading component 13, so that the material loading and unloading component 13 can place the currently picked-up pallet 30 on the material transfer component 14. At the same time, the material unloading component 16 can place the picked-up empty pallet 30 on the material unloading and transport component 15, and the material unloading and transport component 15 can carry the empty pallet 30 and transport it along the first direction to the pallet 30 unloading position.

[0038] The transfer of the pallet 30 containing the workpiece is completed above the unloading and transporting component 15. After the workpiece is removed, the remaining empty pallet 30 is transported away from the unloading and transporting component 15. That is, the transfer path of the pallet 30 on the transport device 10 of this application can be understood as being set from top to bottom, which helps to reduce the floor space.

[0039] Please see Figure 1 Furthermore, both the material transfer component 14 and the unloading and transport component 15 are transported along the first direction, which can further optimize the structural footprint. At the same time, the loading station of the pallet 30 containing the workpiece and the unloading station of the empty pallet 30 can be set at the same end of the transport device 10 near the first direction. This facilitates loading the pallet 30 containing the workpiece and unloading the empty pallet 30 at the same end of the transport device 10, which helps to improve the efficiency of loading and unloading.

[0040] This can be understood as follows: the loading and unloading component 13 serves as the unloading component of the loading and transporting component 12, and also as the unloading component of the transfer component 14. The transfer component 14, as a moving carrier, is used to move the pallet 30 containing the workpiece to the pallet 30 unloading station, and to move the empty pallet 30 to the unloading and unloading component 16 so that the unloading and unloading component 16 can take away the empty pallet 30. Then, the transfer component 14 moves back to the unloading and unloading station of the loading and unloading component 13 to receive the next pallet 30 containing the workpiece. After the transfer component 14 moves away from the unloading and unloading station of the unloading and unloading component 16, the unloading and unloading component 16 can place the empty pallet 30 on the unloading and transporting component 15, and then wait for the next arrival of the transfer component 14 carrying the empty pallet 30, and so on. The workpiece unloading station and the unloading and picking station of the unloading and picking component 16 can be at the same location, and they do not overlap with the picking station of the loading and picking component 13 along the first direction, so that the operation of the loading and picking component 13 and the unloading and picking component 16 can be independent and do not interfere with each other.

[0041] Of course, the dimensional requirements for the transfer component 14 along the first direction are: when the transfer component 14 moves to the pick-up and place station of the loading and unloading component 13, it can not obstruct the unloading and unloading component 16 from placing the empty pallet 30 onto the unloading and transporting component 15; and when the transfer component 14 moves to the pick-up and place station of the unloading and unloading component 16, it can not obstruct the loading and unloading component 13 from taking the pallet 30 containing the workpiece from the loading and transporting component 12.

[0042] It should be noted that the loading and transporting component 12 can be a unidirectional transport configuration or a multidirectional transport configuration. The loading and unloading component 13 and the loading and transporting component 12 are movable relative to each other in the vertical direction. It can be that either the loading and unloading component 13 or the loading and transporting component 12 can be movable relative to the other, or both can be movable. For example, the loading and transporting component 12 can be configured to be movable only in the vertical direction, so that by moving closer to the loading and picking component 13, the loading and picking component 13 can pick up the pallet 30 it carries; the loading and transporting component 12 can also be configured to transport in both the first direction and the vertical direction, so that by moving the pallet 30 in the first direction to a position that is vertically opposite to the picking and placing station of the loading and picking component 13, the pallet 30 is supported in the vertical direction and handed over to the loading and picking component 13; of course, the loading and picking component 13 can also be configured to be movable in the vertical direction, so that it moves downward closer to the loading and transporting component 12 to pick up the pallet 30.

[0043] When the material transfer component 14 moves to the pick-up / placement station of the unloading and picking-up component 16, the arrangement of the unloading and picking-up component 16 and the material transfer component 14 to pick up the empty pallet 30 can be configured in several ways. For example, the unloading and picking-up component 16 can be vertically movable for picking up and placing materials, or the material transfer component 14 can be vertically movable for feeding materials. Alternatively, an intermediate component can be used to transfer the empty pallet 30. For instance, a lifting top component can be installed on the material transfer component 14 to drive the pallet 30 to rise and fall. Any configuration that enables the docking of the empty pallet 30 is acceptable. Furthermore, the placement of the empty pallet 30 between the unloading and picking-up component 16 and the unloading and transport component 15 is similar to the arrangement of the unloading and picking-up component 16 and the material transfer component 14 to pick up the empty pallet 30, and any configuration that satisfies the need for pallet handover is acceptable.

[0044] Please see Figure 1 and Figure 2 Furthermore, the loading and unloading assembly 13 of the above embodiment is exemplified by a vertically movable loading and unloading configuration. Specifically, the loading and unloading assembly 13 includes a first mounting base 131, a first driving member 132, and a first loading and unloading member 133. The first mounting base 131 is disposed on the frame 11, the first driving member 132 is disposed on the first mounting base 131, and the first loading and unloading member 133 is vertically movable and movably disposed on the first mounting base 131. The first loading and unloading member 133 can be used to pick up and place the pallet 30 carried by the loading and transport assembly 12. The first driving member 132 is drivenly connected to the first loading and unloading member 133, and the first driving member 132 can drive the first loading and unloading member 133 to move vertically.

[0045] The first mounting base 131 provides a mounting position and structural stability for the first driving component 132 and the first picking and placing component 133. The first mounting base 131 and the frame 11 can be directly connected or indirectly connected, or they can be set as an integral structure. In this embodiment, the first mounting base 131 is fixedly set on the frame 11 as an example to improve the structural stability of the feeding and picking component 13.

[0046] The first driving member 132 can be any driving structure that can drive the first picking member 133 to move in the vertical direction, such as a cylinder, a motor or a driving module; and the specific picking and placing method of the first picking member 133 can be any setting that meets the needs of the embodiments of this application, such as gripper holding, magnetic attraction or suction cup adsorption.

[0047] In this embodiment, the first driving component 132 is a cylinder and the first picking and placing component 133 is an adsorption part 1332 with an adsorption function as the picking and placing function. The adsorption port of the adsorption part 1332 is made of a flexible material. The adsorption part 1332 is not limited to a suction cup structure. Of course, the adsorption port of the adsorption part 1332 is set vertically downward. In this way, the adsorption port of the adsorption part 1332 has a certain buffer when it contacts the tray 30 downward. At the same time, the cylinder also has a certain buffering effect when it encounters resistance. Therefore, this setting can help protect the tray 30 from force damage.

[0048] The specific working principle is as follows: When the cylinder drives the adsorption part 1332 to descend vertically, it can be used to adsorb the tray 30 carried by the feeding and transporting component 12. Then the cylinder drives the adsorption part 1332 to carry the tray 30 upward. Then the transfer component 14 moves to below the adsorption part 1332. The cylinder drives the adsorption part 1332 to carry the tray 30 downward and place the tray 30 on the transfer component 14. After placement, the cylinder drives the adsorption part 1332 to rise again so that the transfer component 14 can carry the tray 30 away. Then the cylinder drives the adsorption part 1332 to descend again to pick up the tray 30 carried by the feeding and transporting component 12 again. This cycle continues.

[0049] The adsorption part 1332 and the first driving member 132 can be directly driven connected or indirectly connected by an intermediate part. In this embodiment, the first pick-and-place member 133 also includes a first connecting part 1331, and the first connecting part 1331 serves as an intermediate part for driving the adsorption part 1332 and the first driving member 132. The first connecting part 1331 is driven connected to the first driving member 132, and the first connecting part 1331 is arranged to extend along the first direction, for example. The number of adsorption parts 1332 is arranged to be multiple, and the multiple adsorption parts 1332 are spaced apart on the first connecting part 1331 along the first direction. This can help the first driving member 132 to drive multiple adsorption parts 1332 at the same time, and also help to improve the stability of the pick-and-place tray 30 when it is in operation.

[0050] Please see Figure 1 and Figure 2 Furthermore, a second direction is defined, which is parallel to the horizontal plane and forms an angle with the first direction, denoted as Y. Each adsorption part 1332 is independently adjustable along the first direction, the second direction, and the vertical direction, as exemplified by this embodiment where the second direction is perpendicular to the first direction. This means that the adsorption part 1332 can be adjusted in all three dimensions, which helps to coordinate multiple adsorption parts 1332 to the required positions, thereby improving the adsorption effect.

[0051] It should be noted that the number of loading and unloading components 13 in this application embodiment is not limited and depends on the specific needs. In this application embodiment, the loading and unloading components 13 are symmetrically arranged on the frame 11 about the loading and transport components 12, so as to provide symmetrical force for the pallet 30 to be picked up and placed.

[0052] Please see Figures 1 to 3 Similarly, regarding the structural configuration of the unloading and picking component 16 in the embodiments of this application, taking the structural configuration of the loading and picking component 13 in the above embodiments as an example, it will not be described again here.

[0053] Furthermore, the feeding and transporting assembly 12 in the above embodiment is exemplified by being vertically movable. This means that the adsorption part 1332 can move closer to or further away from the feeding and transporting assembly 12 in the vertical direction. This helps reduce the travel distance of the adsorption part 1332 driven by the first driving member 132, thereby improving the picking and placing efficiency of the adsorption part 1332. The feeding and transporting assembly 12 can carry one tray 30 or multiple trays 30, and is generally used to carry multi-layer trays 30. Therefore, the vertically movable configuration of the feeding and transporting assembly 12 can improve the feeding speed.

[0054] Please see Figure 4 and Figure 5 Furthermore, the transport device 10 in the above embodiment may also include a first drive assembly 17, which is drivably mounted on the frame 11 in a vertical direction; the loading and transport assembly 12 includes a second mounting base 121, a second drive member (not shown in the figure), and a first transport member 123. The second mounting base 121 is drivably connected to the first drive assembly 17, and the first drive assembly 17 can drive the second mounting base 121 to move up and down. The second drive member (not shown in the figure) is mounted on the second mounting base 121, and the first transport member 123 is drivably mounted on the second mounting base 121 in a first direction. The second drive member (not shown in the figure) is drivably connected to the first transport member 123, and the second drive member (not shown in the figure) can drive the first transport member 123 to transport the pallet 30 in the first direction.

[0055] It can be understood that the first drive component 17 provides a driving force for the lifting and lowering of the loading and transporting component 12. In this embodiment, the first drive component 17 is a drive module, which can provide a strong driving force. The second mounting base 121 in the loading and transporting component 12 provides a mounting base for the second drive component (not shown in the figure) and the first transport component 123, as well as a structural stabilizing function. The second mounting base 121 can be disposed on the drive end of the first drive component 17, or it can be driven connected to the drive end of the first drive component 17 and movably connected to the frame 11 in the vertical direction, so as to improve the structural stability of the second mounting base 121 during movement.

[0056] The first transport component 123 can be configured to transport the pallet 30, such as a transport belt or roller. In this embodiment, the first transport component 123 is a transport belt, and the second drive component (not shown in the figure) is a drive motor. The drive motor drives the transport belt to run in the first direction, thereby transporting the pallet 30 it carries. This helps the loading and transporting assembly 12 to receive the pallet 30 containing the workpiece and transport the pallet 30 to the required position. It is especially suitable for situations where the loading and transporting assembly 12 has difficulty accurately receiving the pallet 30 in one go.

[0057] Please see Figure 4 and Figure 6 Furthermore, the second mounting base 121 is provided with a stop 124 on the side near the unloading and picking component 16 along the first direction. The stop 124 is used to stop the pallet 30 transported by the first transport component 123. In this embodiment of the application, the stop 124 is set so that when the stop 124 abuts against the pallet 30 along the first direction, the pallet 30 is transported to the target position. After the pallet 30 at the target position is driven to rise by the first drive component 17, it can be directly picked up by the adsorption part 1332.

[0058] Please see Figure 1 , Figure 2 and Figure 7 Furthermore, the transport device 10 of the above embodiment may also include a tray-splitting assembly 19, which includes a third drive member 191 and a tray-splitting member 192. The third drive member 191 is disposed on the frame 11, and the tray-splitting member 192 is drivenly connected to the third drive member 191. The third drive member 191 can drive the tray-splitting member 192 to move along the second direction. The loading and transport assembly 12 can carry multiple layers of pallets 30 loaded with workpieces stacked in the vertical direction. The edge of the pallet 30 is provided with a pressing table 31 that can be pressed and engaged with the tray-splitting member 192 in the vertical direction. The third drive member 191 drives the tray-splitting member 192 to approach the loading and transport assembly 12 in the second direction so as to press the pressing table 31 of the second layer pallet 30 from top to bottom in the vertical direction.

[0059] When the loading and transport assembly 12 carries the multi-layer pallets 30, as the third drive member 191 drives the tray-separating member 192 to approach the loading and transport assembly 12 along the second direction, the tray-separating member 192 gradually moves above the pressure table 31 of the second layer pallet 30. Specifically, the pressing end of the tray-separating member 192 moves between the pressure tables 31 of the first and second layer pallets 30, and then, when the loading and transport assembly 12 rises to cooperate with the transfer assembly 14, the tray-separating member 192 can press against the pressure table 31 of the second layer pallet 30 to prevent adhesion between the multi-layer pallets 30 and affect stability. Alternatively, the loading and transport assembly 12 can rise to a position where the upper surface of the pressure table 31 of the second layer pallet 30 is flush with the lower end of the pressing end of the tray-separating member 192, and then the third drive member 191 can be controlled to drive the tray-separating member 192 to move to the pressure table 31 of the second layer pallet 30 to achieve the pressing action.

[0060] Please see Figure 2 The disc assembly 192 may include a second connecting part 1921 and a pressing part 1922. The second connecting part 1921 is driven to be connected to a third driving member 191. The third driving member 191 can drive the second connecting part 1921 to move along a second direction. The pressing part 1922 can be adjusted and disposed on the second connecting part 1921 along both a first direction and a vertical direction.

[0061] In this embodiment, the tray divider 192 uses a second connecting part 1921 as an intermediate part for driving the connection between the third driving member 191 and the pressing part 1922. The second connecting part 1921 is configured to extend along the first direction, for example. The pressing part 1922 is used to press the pressure table 31 that acts on the tray 30. This configuration can effectively reduce the difficulty of directly connecting the third driving member 191 and the pressing part 1922 and accurately driving them to press the tray 30. Moreover, the pressing part 1922 is connected to the second connecting part 1921 in an adjustable manner along both the vertical and the first direction. With the third driving member 191 driving along the second direction, the pressing part 1922 can accurately press in a more precise and adjustable state.

[0062] Please see Figure 1 Furthermore, the transport device 10 of the above embodiment may also include a transmission component 18, which is transportably disposed on the frame 11 along the first direction and located on the side of the loading transport component 12 away from the unloading and picking component 16 along the first direction. The transmission component 18 can transport the pallet 30 to the first transport component 123 along the first direction.

[0063] The transmission component 18 can be understood as providing the pallet 30 containing the workpiece to the loading and transporting component 12. The configuration of the transmission structure of the transmission component 18 along the first direction can refer to the configuration of the transmission structure of the loading and transporting component 12 along the first direction in the above embodiments. For example, a drive component can be used to drive the conveyor belt to transport the pallet 30 along the first direction, which will not be elaborated here. By setting the transmission component 18 in this application embodiment, the loading of the pallet 30 containing the workpiece can be buffered and sudden failures can be dealt with. For example, when a short-term speed fluctuation or failure occurs in a certain link of the pallet 30 flow, such as the sudden increase in the discharge speed of the upstream equipment or the temporary limitation of the feeding speed of the downstream equipment, the transmission component 18 can temporarily store a certain amount of the pallet 30 containing the workpiece, avoiding the accumulation or blockage of the pallet 30 containing the workpiece at a certain node, thereby ensuring the continuous and stable operation of the entire system and effectively preventing system stagnation caused by local problems.

[0064] For example, in the face of emergencies such as sudden equipment failure and repair or temporary power outages, the pallet 30 containing the workpieces stored in the transmission component 18 can buy the system some recovery time, reduce losses caused by production interruptions, and improve the fault tolerance of the entire transportation system to abnormal situations.

[0065] For operations requiring precise timing, the transfer component 18 can reduce waiting time between devices. For example, in the process of automatically placing a pallet 30 containing workpieces into the transfer component 18, if downstream material stacking prevents the receiving of empty pallets 30 (i.e., the empty pallets 30 cannot be removed from the material conveying component 15 in time), the automatic loading device for the pallet 30 containing workpieces can place it into the transfer component 18 and continue performing other tasks instead of waiting in place. This fully utilizes the working time of the automatic loading device and improves operational efficiency.

[0066] Please see Figure 4 and Figure 6 Furthermore, the transport device 10 in the above embodiment may also include a transfer component 20. The transfer component 20 is elliptical and detachable on the frame 11 and located below the unloading and picking component 16. The transfer component 20, the unloading and picking component 16, and the unloading transport component 15 can respectively transfer pallets 30. When the transfer component 20 rises, it can receive the pallet 30 from the unloading and picking component 16. When the transfer component 20 falls, it can place the pallet 30 into the unloading transport component 15.

[0067] In this embodiment of the application, the unloading and picking component 16 places the empty pallet 30 onto the unloading and transporting component 15, specifically through the transfer component 20. Specifically, after the workpiece on the pallet 30 is unloaded, the unloading and picking component 16 picks up the empty pallet 30. After the transfer component 14 moves away from the picking and placing station of the unloading and picking component 16, the transfer component 20 is controlled to rise to the picking and placing station of the unloading and picking component 16, so that the unloading and picking component 16 places the empty pallet 30 onto the transfer component 20. Then the transfer component 20 descends and transfers the empty pallet 30 to the unloading and transporting component 15.

[0068] Specifically, the transfer component 20 may include a fourth drive component 201 and a transfer component 202. The fourth drive component 201 is disposed on the frame 11, and the transfer component 202 is drivenly connected to the fourth drive component 201. The transfer component 202 and the unloading and transporting component 15 can be inserted opposite each other in the vertical direction. The fourth drive component 201 can drive the transfer component 202 to move up and down in the vertical direction. The fourth drive component 201 drives the transfer component 202 to rise, so that it can receive the pallet 30 from the unloading and picking component 16. The fourth drive component 201 drives the transfer component 202 to fall down to pass through the unloading and transporting component 15, so that the pallet 30 can be placed in the unloading and transporting component 15.

[0069] The fourth driving component 201 is a driving module, but it can also be other driving components that meet the requirements, such as a drive motor. The transfer component 202 is a horizontal load-bearing structure. The transfer component 202 is set at the driving end of the fourth driving component 201, or the transfer component 202 is driven to connect with the fourth driving component 201 and is movably connected to the frame 11 in the vertical direction to improve the structural stability during the lifting and moving process. The fourth driving component 201 drives the transfer component 202 to rise to receive the pallet 30 from the unloading and picking component 16; while the fourth driving component 201 drives the transfer component 202 to fall to place the pallet 30 onto the unloading and transport component 15.

[0070] In this embodiment, the transfer component 202 and the unloading transport assembly 15 can be arranged opposite each other or avoid each other in the vertical direction. Thus, during the descent of the transfer component 202 driven by the fourth drive component 201, the transfer component 202 passes through the unloading transport assembly 15 in the vertical direction, or is passed through by the unloading transport assembly 15, thereby transferring the empty pallet 30 carried by the transfer component 202 onto the unloading transport assembly 15. Specifically, in this embodiment, the unloading transport assembly 15 is configured with a double-track conveyor belt along the first direction, and the transfer component 202 can be arranged vertically between the double-track conveyor belts.

[0071] Please see Figure 1It should be noted that the transport device 10 in the above embodiment may also include a camera recognition component 21, which is disposed above the frame 11 and is used to detect and recognize the position and status of the pallet 30 to help the pallet 30 be accurately positioned.

[0072] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
