[0030] Example 1 Reference Figure 1~Figure 2 , which is the first embodiment of the present invention, provides a logistics robot for warehousing and transportation, comprising: A base 100, a rotating wheel for the robot to travel is rotatably provided at the bottom of the base 100, a protective shell 200 is fixedly provided on the top of the base 100, an inclined slot is provided at the center of the side of the protective shell 200, and an electric conveyor belt 300 for outputting goods is rotatably provided inside the inclined slot, a fixing rod 400 is also fixedly provided on the top of the base 100, a pair of fixing rods 400 are provided and symmetrically arranged on both sides of the base 100, a bearing plate 500 is sleeved and slidably provided on the side of the fixing rod 400, and, The fixing assembly 600 is used for the goods on the carrying plate 500, and includes a clamping member 601 and an ejecting member 602 disposed on the top of each carrying plate 500. A pair of clamping members 601 are disposed on the top of each carrying plate 500, and the clamping members 601 are symmetrically disposed on both sides of the carrying plate 500. The ejecting member 602 is located in the middle part of the carrying plate 500 and between the clamping members 601; The lifting assembly 700 is used to control the lifting of each supporting plate 500 , and includes a driving member 701 disposed on the top of the base 100 and a control member 702 disposed on the side of the driving member 701 .

[0031] In the present invention, multiple carrier plates 500 are provided for placing goods, thereby improving the efficiency of the logistics robot. In actual use, each logistics robot places goods on the carrier plates 500 from bottom to top in sequence according to the height of different carrier plates 500. Different carrier plates 500 can place goods from the same placement port or goods from different placement ports.

[0032] Example 2 Reference Figure 3~Figure 4 , which is the second embodiment of the present invention. The embodiment is different from the first embodiment in that: the clamping member 601 includes a side plate 601a, a movable plate 601b, an extrusion spring 601c, a limit frame 601d, a push rod 601e and a load-bearing wheel 601f. The side plate 601a is fixedly arranged on the top of each load-bearing plate 500, the movable plate 601b is slidably arranged on the top of the load-bearing plate 500, the two ends of the extrusion spring 601c are respectively fixedly arranged on the sides of the side plate 601a and the movable plate 601b, the limit frame 601d penetrates the side plate 601a and is fixedly arranged on the side of the movable plate 601b, the push rod 601e is located at the end of the limit frame 601d, the push rod 601e penetrates the side of the limit frame 601d and is threadedly connected with the limit frame 601d, and a plurality of wheel grooves are arranged in the middle part of the load-bearing plate 500, and a plurality of load-bearing wheels 601f are arranged and are rotatably arranged on the inner sides of the wheel grooves.

[0033] The clamping member 601 is used to clamp the goods to prevent the goods from falling off the carrying plate 500 during transportation. The carrying wheels 601f are evenly laid on the surface of the carrying plate 500 to support the goods and reduce the friction between the goods and the carrying plate 500 to facilitate the delivery of the goods. The parts of the clamping member 601 except the carrying wheels 601f are provided in two groups and symmetrically arranged on both sides of the carrying plate 500.

[0034] The ejector 602 includes a fixed plate 602a, an arc plate 602b, a top plate 602c, an ejector spring 602d, a snap ring 602e, a rotating plate 602f, a return spring 602g and a step frame 602h. The fixed plate 602a is fixedly arranged at the middle part of the side of the carrier plate 500. The arc plate 602b is provided with a pair of and fixedly arranged at both sides of the fixed plate 602a. One end of the ejector rod 601e away from the side plate 601a abuts against the side of the arc plate 602b. The top plate 602c is slidably arranged on the surface of the carrier plate 500. The ejector spring 602d is fixedly arranged on the carrier plate 500. The fixing plate 602a is fixedly arranged on the side opposite to the top plate 602c, the retaining ring 602e is fixedly arranged on the side of the top plate 602c close to the fixing plate 602a, a through hole is opened at the center of the fixing plate 602a, the rotating plate 602f is rotatably arranged on the inner side of the through hole, and a groove bend for engaging with the retaining ring 602e is arranged at one end of the rotating plate 602f close to the retaining ring 602e, the two ends of the return spring 602g are respectively fixedly arranged on the side opposite to the base 100 and the rotating plate 602f, and the step frame 602h is fixedly arranged on the top of the base 100 and is located in the middle position.

[0035] Each supporting plate 500 is installed with a rotating plate 602f, and the side of each rotating plate 602f away from the retaining ring 602e extends beyond the supporting plate 500 by a certain distance. Different rotating plates 602f extend out of the supporting plate 500 by different distances and increase successively with the height of the supporting plate 500. The side of the ladder frame 602h close to the supporting plate 500 is provided with steps of different heights, and each step corresponds to a part of a different rotating plate 602f extending out of the supporting plate 500.

[0036] Among them, the ejection spring 602d has a relatively large force, and the thrust generated by it can overcome the friction generated by the movable plate 601b and the goods. When the goods are clamped, the ejection spring 602d is in a compressed state, and the snap ring 602e is clamped inside the groove of the rotating plate 602f, so the top plate 602c will not be ejected. In addition, after the carrier plate 500 is lowered, the rotating plates 602f of different heights can be in contact with the steps on the side of the ladder frame 602h from bottom to top, and the rotating plate 602f supported by the steps rotates, thereby causing the return spring 602g to contract, and the snap ring 602e to separate from the rotating plate 602f.

[0037] When in use: the loading worker places the goods on different load plates 500. When placing the goods, the load plate 500 is first placed on the load plate 500, and then the top plate 602c is pressed by one side of the goods. The top plate 602c is pressed to compress the ejection spring 602d, and the clamping ring 602e is also clamped in the inner groove of the rotating ring as the top plate 602c moves. On the other side, as the top plate 602c moves, the top plate 602c moves from the protrusion of the arc plate 602b to the concave part, so that the limiting frame 601d and the movable plate 601b are close to the goods under the action of the squeezing spring 601c, and the goods are clamped.

[0038] Among them, the top rod 601e can use the threaded adjustment to the position of the limit frame 601d and the movable plate 601b, so as to adapt to the clamping requirements of goods of different sizes. For example, when the width of the goods is large, the movable plate 601b will clamp the goods too tightly and make it impossible to put them in. At this time, the top rod 601e can be rotated to move the movable plate 601b closer to one side of the side plate 601a to increase the space between the movable plates 601b. Conversely, the movable plate 601b can be moved away from one side of the side plate 601a to reduce the space between the movable plates 601b.

[0039] When delivering goods, the goods on the lowest load-bearing plate 500 are delivered first. At this time, it is only necessary to use the lifting assembly 700 to move the load-bearing plate 500 down to the position of the electric conveyor belt 300, and then the rotating plate 602f touches the step of the ladder frame 602h, and the rotating plate 602f then rotates, and the retaining ring 602e is disengaged from the groove of the rotating plate 602f, and the top plate 602c that has lost its restraint begins to move toward one end of the goods under the elastic force of the ejection spring 602d. In this process, the arc plate 602b slides and pushes the ejector rod 601e open, thereby making the movable plate 601b away from the goods, and the goods that lose the clamping of the movable plate 601b are ejected by the top plate 602c, and then are conveyed to the delivery port by the electric conveyor belt 300.

[0040] The remaining structures are the same as those of Example 1.

[0041] Example 3 Reference Figure 5~Figure 7, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the driving member 701 includes a driving motor 701a, a rotating rod 701b, a support plate 701c, a primary pulley 701d, a secondary pulley 701e and a transmission belt 701f. The driving motor 701a is fixedly arranged on the top of the base 100, the rotating rod 701b is fixedly arranged on the output end of the driving motor 701a through a coupling, the support plate 701c is located on one side of the bearing plate 500 and is fixedly arranged on the top of the base 100, the primary pulley 701d is rotatably arranged on one end of the support plate 701c close to the base 100, the secondary pulley 701e is rotatably arranged on one end of the support plate 701c away from the base 100, and the two ends of the transmission belt 701f are respectively sleeved on the sides of the primary pulley 701d and the secondary pulley 701e.

[0042] The support plate 701c is provided with multiple pieces on one side of the supporting plate 500 which are arranged respectively. The rotating rod 701b passes through the side of the support plate 701c and is coaxially arranged with the main pulley 701d. The heights of different support plates 701c increase successively along the direction from the rotating rod 701b to the driving motor 701a. The transmission belts 701f on the sides of different support plates 701c are fixedly connected to the supporting plates 500 at different heights respectively.

[0043] The control member 702 includes a docking groove 702a, a sliding hole 702b, a sliding wheel 702c, a return spring 2 702d, a block 702e, an extrusion rod 1 702f, a slide rail 702g, an extrusion rod 2 702h and a return spring 3 702i. The docking groove 702a is opened on the side of each pulley away from the support plate 701c, the sliding hole 702b is opened on the side of the rotating rod 701b, the sliding wheel 702c is sleeved and slidably set on the side of the rotating rod 701b, the central part of the sliding wheel 702c is slidably set on the inner side of the sliding hole 702b, the two ends of the return spring 2 702d are respectively fixed on the side of the sliding wheel 702c and the side of the rotating rod 701b, and the block 702e is fixed on the side of the sliding wheel 702c close to the docking groove 702a and matches the shape of the docking groove 702a.

[0044] The first extrusion rod 702f is provided with a plurality of extrusion rods and fixedly arranged on the side of the bearing plate 500 at different heights through an electric push rod. Except for the highest bearing plate 500, the slide rail 702g is fixedly arranged on the side of each bearing plate 500. The second extrusion rod 702h is slidably arranged on the inner side of the slide rail 702g through a bracket. The two ends of the return spring 3 702i are respectively fixedly arranged on the side of the bracket of the second extrusion rod 702h and the side of the slide rail 702g. After receiving the signal, the electric push rod can automatically drive the first extrusion rod 702f to be extended and retracted.

[0045] The extension length of the electric push rod between the extrusion rod 1 702f and different supporting plates 500 increases arithmetic progression as the height of the supporting plate 500 increases, the connecting bracket between the extrusion rod 2 702h and different slide rails 702g increases arithmetic progression as the height of the supporting plate 500 increases, and the extrusion rod 1 702f and the extrusion rod 2 702h between adjacent supporting plates 500 are respectively located on different sides of the sliding wheel 702c in the axial direction of the rotating shaft.

[0046] The first return spring 2 702d from the rotating rod 701b to the driving motor 701a always pushes the block 702e to the inside of the docking groove 702a through the sliding wheel 702c, and the blocks 702e of the remaining sliding wheels 702c are always not engaged with the docking groove 702a under the pulling of the return spring 2 702d.

[0047] Among them, the first return spring 2 702d from the rotating rod 701b to the driving motor 701a is used to control the lifting of the lowest load-bearing plate 500. Since the return spring 2 702d always pushes the block 702e to the inside of the docking groove 702a through the sliding wheel 702c, the driving motor 701a can always control the lifting of the lowest load-bearing plate 500 under normal conditions. In addition, the elastic force of the return spring 3 702i is greater than that of the return spring 2 702d.

[0048] When in use: the lifting assembly 700 is mainly used to control the orderly lifting of the carrier plate 500, wherein the driving member 701 mainly provides the driving force for the lifting of the carrier plate 500 through the driving motor 701a, and the control member 702 can control the lifting order of the carrier plate 500.

[0049] After the logistics robot moves to the fixed delivery port, if it is necessary to deliver the goods on the lowest load-bearing plate 500, the robot controls the driving motor 701a to rotate. Since the block 702e is engaged with the docking groove 702a, the rotating rod 701b rotates to drive the sliding wheel 702c, and the sliding wheel 702c drives the main pulley 701d to rotate, and then drives the secondary pulley 701e to rotate, and finally drives the transmission belt 701f. After the transmission belt 701f rotates, it moves the load-bearing plate 500 downward. When the rotating plate 602f of the lowest load-bearing plate 500 touches the ladder frame 602h, the goods are ejected by the top plate 602c, and the delivery of the lowest goods is completed.

[0050] When the lowest load-bearing plate 500 is lowered, the second squeezing rod 702h on its side also starts squeezing the side of the second sliding wheel 702c, and the second sliding wheel 702c is used to control the second-to-last load-bearing plate 500. After the squeezing rod 702h and the sliding wheel 702c are squeezed, the sliding wheel 702c is squeezed by the squeezing rod 702h and slides, and then squeezes the block 702e to the inner side of the docking groove 702a, thereby achieving the clamping connection between the rotating rod 701b and the main pulley 701d, so that the rotating rod 701b can control the lifting of the second-to-last load-bearing plate 500. At the same time, due to the lowering of the lowest load-bearing plate 500, the squeezing rod 1 702f squeezes the side of the first sliding wheel 702c, so that the sliding wheel 702c drives the block 702e to disengage from the docking groove 702a, and the rotating rod 701b can no longer control the lifting of the lowest load-bearing plate 500.

[0051] After the goods on the penultimate layer of the load board 500 are placed, the squeezing rod 1 702f on the side squeezes the sliding wheel 702c directly below, so that the block 702e is separated from the docking groove 702a, and the squeezing rod 2 702h on the side squeezes the sliding wheel 702c directly below to clamp the corresponding block 702e with the docking groove 702a. Although the sliding wheel 702c at this time is squeezed by the squeezing rod 2 702h, the squeezing rod 1 702f can overcome the elastic force of the return spring 3 702i. Finally, the rotating rod 701b no longer controls the lifting and lowering of the penultimate layer of the load board 500, but switches to controlling the third layer of the load board 500. By progressive conversion in this way, the control member 702 can control the lifting and lowering sequence of the multi-layer load boards 500.

[0052] The engagement of the clamping block 702e with the docking groove 702a requires that the sliding block is squeezed by the squeezing rod 702h. When the sliding block rotates with the rotating rod 701b, the clamping block 702e is squeezed into the docking groove 702a by the squeezing force.

[0053] When the height of each carrier plate 500 needs to be restored, the robot only needs to control the electric push rods on the side of the carrier plates 500 at different heights to retract a certain distance, so that the sliding wheel 702c can be freed from the squeezing of the squeezing rod 1 702f, and then the control of the rotating rod 701b on the main pulley 701d is restored. Since the sliding wheel 702c corresponding to the highest carrier plate 500 is only squeezed by the squeezing rod 1 702f on its side, it is restored to its height first, and the final restoration order is from high to low.

[0054] Through the lifting assembly 700, each carrying plate 500 can lift the goods separately. This setting is to ensure the safety and accuracy of the goods when they are dropped. As long as the distance to the drop-off port is close enough, the goods can be dropped more accurately and the safety of the goods themselves can be guaranteed.

[0055] The remaining structure is the same as that of Example 2.
