[0030] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0031] The inventors have discovered through research that during the product production process, loaded product shelves are usually transferred from the head-end placement area to the tail-end placement area, and the empty shelves are transferred to the head-end placement area by another conveyor line. Because the space at the head-end position is limited, it is easy for shelves to pile up in the head-end placement area. Therefore, it is necessary to monitor the number of shelves in the head-end placement area in real time, which increases the labor intensity of the staff.

[0032] Please refer to Figure 1 The material handling system 100 provided in the embodiment of the present utility model can solve the above-mentioned problems, which will be described in detail below.

[0033] refer to Figure 1 The material handling system 100 includes a head-end placement area 110, a tail-end placement area 120, an empty shelf placement area 130 and a transport vehicle 140; wherein the empty shelf placement area 130 is arranged between the head-end placement area 110 and the tail-end placement area 120, the empty shelf placement area 130 is used to place empty shelves, the head-end placement area 110 is used to load products on the empty shelves, the tail-end placement area is used to place shelves loaded with products, and the transport vehicle 140 is used to transfer shelves between the empty shelf placement area 130 and the head-end placement area 110, and between the head-end placement area 110 and the tail-end placement area 120.

[0034] The material handling system 100 can transfer the empty shelves to the head-end placement area 110 when the transport vehicle 140 returns from the tail-end placement area 120 to the head-end placement area 110 after the transport vehicle 140 has transported the shelves loaded with products. This can avoid the phenomenon of the transport vehicle 140 turning over empty, eliminate the need to monitor the head-end placement area 110 in real time, avoid shelf accumulation, and reduce the labor intensity of the staff.

[0035] It should be noted that the empty shelves prevented by the empty shelf placement area 130 mainly come from the subsequent processes, and the operation position of the subsequent processes is close to the tail end placement area 120 relative to the head end placement area 110 .

[0036] In addition, during the transportation process, a QR code may be posted on the shelf, and the transport vehicle 140 scans and reads the QR code to perform targeted transportation operations.

[0037] refer to Figure 1 The material handling system 100 further includes a welding area 150 , which is provided with at least two sets of welding mechanisms 151 , and the welding mechanisms 151 are used to perform welding operations on products on the shelves transferred from the head-end placement area 110 to the tail-end placement area 120 .

[0038] In the above technical solution, by setting up the welding area 150 and arranging the welding mechanism 151, welding operations can be interspersed during the transportation process of the product, which can improve the space utilization rate of the site.

[0039] It is worth noting that there are three groups of welding mechanisms 151 , which are arranged at equal intervals, and transition areas 152 are provided between adjacent groups of welding mechanisms 151 .

[0040] In this embodiment, in order to improve the timing stability during the transfer process and ensure the product accuracy, the product is usually welded three times in order, and a transition area 152 is provided for placing products between adjacent groups of welding processes. Of course, in other embodiments of the utility model, the number of welding mechanisms 151 can be one, two, four, etc., so as to integrate or decentralize the existing welding processes.

[0041] It should be noted that when different welding processes take different amounts of time, the number of welding mechanisms 151 arranged in different groups can be different based on the difference in time. The specific number of welding mechanisms 151 arranged in a group depends on the actual situation.

[0042] refer to Figure 2The welding mechanism 151 includes a positioning bracket 1511 and a welding arm 1512. The positioning bracket 1511 is used to cooperate with the shelf, and the welding arm 1512 is used to weld the products on the shelf, and the positioning bracket 1511 is provided on both sides of the welding arm 1512.

[0043] When the transport vehicle 140 moves to a position corresponding to the positioning bracket 1511, an external force can be used to transfer the shelf loaded with products on the transport vehicle 140 to the positioning bracket 1511, and the positioning bracket 1511 positions the shelf to improve welding stability. The process of the shelf moving from the transport vehicle 140 to the positioning bracket 1511 can be assisted by the force arm on the transport vehicle 140 or by the welding force arm 1512.

[0044] refer to Figure 1 The empty rack placement area 130 is provided with a plurality of empty rack placement stations 131, and the plurality of empty rack placement stations 131 are arranged in sequence from the head end placement area 110 to the tail end placement area 120.

[0045] It should be noted that when placing empty shelves on the empty shelf placement station 131, placing them in sequence from the tail end placement area 120 to the head end placement area 110 can reduce the movement of the empty shelves when they are placed, and will not have a practical impact on the moving range of the transport vehicle 140.

[0046] refer to Figure 1 The material handling system 100 also includes at least two charging stations 160 , and the at least two charging stations 160 are staggered between the empty rack placement stations 131 .

[0047] In the above technical solution, a charging station 160 is provided to charge and supply energy to the transport vehicle 140 to ensure that the transport vehicle 140 can efficiently perform the transport operation.

[0048] It is worth noting that the transport vehicle 140 is usually set with a lower power limit monitoring. When the power is lower than 20%, it needs to be recharged to avoid affecting the transport efficiency when the power is low.

[0049] refer to Figure 1 The material handling system 100 also includes a maintenance area 170, which is arranged on one side of the empty shelf placement area 130 close to the tail end placement area 120. By setting up the maintenance area 170, on the one hand, the transport vehicle 140 can be maintained, and on the other hand, the products returned from the later process can be inspected and checked.

[0050] refer to Figure 1In order to improve the driving stability of the transport vehicle 140, the material handling system 100 may further include a first guide rail 180 and a second guide rail 190 arranged in parallel. During the handling process, the transport vehicle 140 is used to move from the head-end placement area 110 to the tail-end placement area 120 along the first guide rail 180. The transport vehicle 140 is used to move from the tail-end placement area 120 to the head-end placement area 110 along the second guide rail 190, thereby making the transportation of the transport vehicle 140 proceed in an orderly manner and avoiding crowding.

[0051] In addition, a plurality of third guide rails are provided between the first guide rail 180 and the second guide rail 190 and each workstation, so as to ensure that the relative position between the transport vehicle 140 and each workstation is accurate.

[0052] In addition, a spacing detection sensor can be installed on the transport truck 140. When another transport truck 140 or other foreign objects appear in front of the transport truck 140, a signal can be sent to the transport truck 140, causing the transport truck 140 to stop and sound an alarm, thereby immediately eliminating safety hazards and fully ensuring the safety of the transported shelves and products on the shelves.

[0053] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
