[0009] By adopting the above technical solution, when the conveyor belt descends, the lowermost conveyor belt is supported by the bottom bracket, which can reduce the bearing capacity of the driving device.

[0010] The utility model is further configured that the top surface of the bottom bracket is rotatably provided with a roller that cooperates with the conveyor belt.

[0011] By adopting the above technical solution, when the conveyor belt is conveying, the roller will cooperate with the conveyor belt to reduce the friction between the conveyor belt and the base.

[0012] The utility model is further configured that the driving device comprises a servo motor and a screw rod which is transmission-connected to the servo motor, and the screw rod passes through the brackets of all conveyor belts and is threadedly connected thereto.

[0013] By adopting the above technical solution, the servo motor and the screw rod can accurately raise and lower the conveyor belt according to the preset conditions.

[0014] The utility model is further configured that the loading platform of the AGV is provided with a clearance groove for placing the lifting frame.

[0018] The utility model is further configured that four positioning pins are provided and are respectively located at four corners.

[0019] By adopting the above technical solution, the four corners have higher stability.

[0020] The utility model is further configured that the top end of the positioning pin is provided with a chamfer.

[0021] By adopting the above technical solution, the chamfer has a guiding function, which makes it convenient for the positioning pin to penetrate into the positioning groove, thereby facilitating positioning.

[0022] The utility model is further configured that the conveyor belts are provided with two groups.

[0023] By adopting the above technical solution, the two sets of conveyor belts can carry more materials on the one hand, and will not take up too much loading time on the other hand.

[0024] In summary, the utility model mainly has the following beneficial effects:

[0025] 1. By setting a lifting frame on the loading platform of the AGV and setting at least two sets of conveyor belts up and down in the lifting frame, when the material is output from the discharge port of the previous process, it will enter the conveyor belt until it touches the touch switch.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0033] The following describes an embodiment of the utility model based on its overall structure.

[0034] A material transfer robot, such as Figure 1 As shown, it includes AGV1, and a lifting frame 2 is installed on the loading platform 101 of AGV1. Figure 1 and Figure 2As shown, in some embodiments, the lifting frame 2 is placed on the loading platform 101. In order to place it more stably, in some embodiments, a clearance groove 9 for the lifting frame 2 to be placed is provided on the loading platform 101 of the AGV 1, and the lifting frame 2 is placed in the clearance groove 9. In a preferred embodiment, a positioning pin 10 is provided in the clearance groove 9, and a positioning groove (not shown in the figure) that cooperates with the positioning pin 10 is provided on the lifting frame 2. The positioning of the clearance groove 9 can be achieved through the cooperation of the positioning pin 10 and the positioning groove. Preferably, four positioning pins 10 are provided and located at four corners respectively, and the top of the positioning pin 10 is preferably chamfered so that the positioning pin 10 can penetrate into the positioning groove.

[0035] like Figure 1 and Figure 2 As shown, at least two groups of conveyor belts 3 are movably arranged in the lifting frame 2, and the conveyor belts 3 are driven to rotate by a servo motor, gears, chains, and rollers (gears, chains, and rollers are not shown) in the prior art. In some embodiments, the conveyor belts 3 are provided in two groups, and the two groups of conveyor belts 3 are distributed up and down, and the two side brackets 301 of the conveyor belts 3 are connected to the lifting frame 2 through the guide rails 201, so that the conveyor belts 3 can only move up and down along the guide rails 201.

[0036] like Figure 1 and Figure 2 As shown, in some embodiments, the conveyor belt 3 is driven to rise and fall by a driving device 4, and the driving device 4 is preferably a combination of a servo motor 401 and a screw rod 402, the screw rod 402 is transmission-connected to the servo motor 401, and the screw rod 402 passes through the brackets 301 of all conveyor belts 3 and is threadedly connected to the brackets 301. After the servo motor 401 is driven, all conveyor belts 3 will be raised and lowered synchronously.

[0037] like Figure 1 and Figure 2 As shown, the end of the conveyor belt 3 is provided with an end plate 5 fixed to the brackets 301 on both sides thereof, and the end plate 5 can prevent the material from falling off from this end. In addition, the end plate 5 is provided with a touch switch 6 facing the conveyor belt 3. When the material touches the touch switch 6, the drive device 4 drives the conveyor belt 3 to rise. When the material is output from the discharge port of the previous process, it will enter the conveyor belt 3 until it touches the touch switch 6. At this time, the drive device 4 drives the conveyor belt 3 to rise one station, and moves the unloaded conveyor belt 3 below to connect with the discharge port. Then the material can be respectively conveyed to the conveyor belt 3 on different layers, so that the AGV1 can load multiple layers of material at one time.

[0038] like Figure 1 and Figure 2 As shown, after AGV1 transports the material to the designated location, it first transports the material on the lower conveyor belt 3, and then the servo motor 401 drives the upper conveyor belt 3 to move downward and delivers the material on the upper conveyor belt 3.

[0039] like Figure 3 and Figure 4 As shown, in order to reduce the load-bearing capacity of the screw rod 402, in some embodiments, the lifting frame 2 is provided with a bottom support 7 at the bottom of the lowest conveyor belt 3. When the conveyor belt 3 descends, the lowest conveyor belt 3 is supported by the bottom support 7. The top surface of the bottom support 7 is rotatably provided with a roller 8 that cooperates with the conveyor belt 3. The roller 8 can cooperate with the rotation of the conveyor belt 3.

[0040] It is worth noting that all electronic components in this solution are electrically connected to the controller, wherein the electronic components include the servo motor 401, the touch switch 6, the AGV1, etc., and the start-up sequence and start-up duration of each electronic component can be controlled by the controller.

[0041] In summary, the utility model mainly has the following beneficial effects: when the material is output from the discharge port of the previous process, it will enter the conveyor belt 3 until it touches the touch switch 6. At this time, the driving device 4 drives the conveyor belt 3 to rise one station, and moves the empty conveyor belt 3 below to connect with the discharge port. Then the material can be transmitted to the conveyor belts 3 on different layers respectively, so that AGV1 can load multiple layers of material at a time.

[0042] When AGV1 delivers the material to the designated location, it first delivers the material on the lower conveyor belt 3, and then the servo motor 401 drives the upper conveyor belt 3 to move downward and delivers the material on the upper conveyor belt 3. The whole process can realize the loading of multiple layers of materials and improve the transfer efficiency of the transfer robot.
