Description

Technical Field

[0001] The present invention relates to the technical field of logistics handling, and in particular to a material box handling logistics robot. Background Art

[0002] The existing technology proposes a "target cargo box to person" picking method to solve the waste of resources and energy caused by the traditional "inventory container to person" picking method. The "target cargo box to person" picking method uses a handling robot to move the target cargo box instead of the inventory container to the picking area: after receiving the order instruction, the robot moves to the warehouse channel in front of the target cargo box; the robot rotates and reverses so that the front of the robot faces the target cargo box, and the telescopic mechanism on the robot extends to take the target cargo box out of the warehouse container and place it on the robot's own target cargo box storage rack; after the robot completes the gripping of the target cargo box, it rotates and reverses again so that the robot faces the warehouse channel, so that the robot can carry the target cargo box to the designated location along the storage channel.

[0003] After searching, the Chinese patent publication number CN117401611B discloses a material box picking robot, which relates to the technical field of warehouse management equipment, including a bracket, the lower end of the bracket is fixedly connected to a vehicle body, a moving component is arranged in the vehicle body, a lifting component is fixedly connected to the surface of the vehicle body, a clamping fork is arranged on the lifting component, four material box cache plates are fixedly connected to the inner wall of the bracket, the side walls of the four material box cache plates are commonly fixedly connected to the side plates, the lower ends of the side plates are fixedly connected to the top surface of the vehicle body, fixing clamps are arranged on both sides of the four material box cache plates, the inner walls of the four material box cache plates are slidably connected to baffles, and transportation components are arranged on the four material box cache plates.

[0004] The above technical solution, through the mutual cooperation between structures, has the effect of enabling multi-layer shelf storage, increasing the maximum throughput of storage and improving the protection of goods. However, when in use, there is only one clamping fork. Therefore, when multiple material boxes are transported, the clamping fork needs to be repeatedly moved and clamped, which reduces the work efficiency. Moreover, when the clamping fork is damaged, the entire robot cannot be used any longer, thereby reducing its practicality. In addition, there is sliding friction between the material box and the clamping fork, which easily causes wear on the robot and the material box. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a material box handling logistics robot, which solves the problems raised in the background technology.

[0010] Through the above technical solution, the rotation of the synchronous belt can drive the second rotating shaft to move. Under the action of the connecting plate, connecting shaft, supporting wheel and limiting ring groove, the second rotating shaft can always keep moving without self-rotation, so that the transported material box can remain in a horizontal state.

[0026] Through the above technical solution, the two sides of the material box can be squeezed and supported by the provided squeezing rollers, and the wear on the side edges of the material box when the position of the material box is adjusted can be reduced.

[0027] The present invention provides a material box handling logistics robot. It has the following beneficial effects:

[0028] 1. The material box handling logistics robot is provided with a rotating mechanism and multiple horizontal holding mechanisms. The rotating mechanism can keep each material box being handled in a horizontal state under the cooperation of the horizontal holding mechanism without tilting. When in use, it can not only handle multiple material boxes, but also directly lift and handle the corresponding material boxes without repeated handling operations, thereby improving work efficiency. Moreover, when a single telescopic clamping mechanism is damaged, the others can operate normally without stopping for maintenance, thereby further improving work efficiency, thereby solving the problems that the existing material box handling logistics robot has only one handling mechanism, which requires repeated handling operations and reduces work efficiency, and cannot be used when damaged, thereby reducing practicality.

[0029] 2. The material box handling logistics robot, through the setting of switching mechanism, adjustable support mechanism and telescopic clamping mechanism, can not only clamp and carry material boxes of any size, but also limit and press the material boxes during the handling process, which can prevent the material boxes from shaking and tilting, thereby improving stability.

[0030] 3. The material box handling logistics robot changes the original friction contact with the material box into rolling contact through the setting of rolling contact mechanism, which can reduce the friction between the outer surface of the material box and the inner wall of the robot, reduce wear, and thus improve quality.
