[0028] To further understand the content of the present utility model, the present utility model will be described in detail in combination with the accompanying drawings and embodiments. What is described here is only the preferred embodiment of the present utility model. Those skilled in the art can think of other ways to implement the present utility model based on the preferred embodiment, and such other ways also fall within the scope of the present utility model.

[0029] Embodiment 1

[0030] Referring to Figures 1 - 5 , this embodiment provides a material transfer trolley, which includes a vehicle frame 1. A plurality of storage spaces are surrounded on the vehicle frame 1. An access opening is provided on one side of each storage space. The access openings of the plurality of storage spaces face different sides. Material taking robots or material taking personnel can be arranged on different sides of the vehicle frame 1 to realize taking and transferring materials simultaneously on different sides of the vehicle frame 1. Compared with the existing storage trolley with material taking in a single position direction, it has higher material transfer efficiency and is beneficial to improving the production efficiency of actual products such as lithium batteries.

[0031] It should be noted that there are two layers of storage layers in this embodiment, and more layers can also be designed according to actual needs, such as three layers, four layers, etc. The multi-layer storage layers are arranged longitudinally along the vehicle frame 1, which can make full use of the longitudinal space of the vehicle frame 1, increase the storage space of the vehicle frame 1, and can temporarily store more lithium battery NG materials. Each storage layer includes a storage space. The access openings of the storage spaces on adjacent two storage layers are arranged opposite to each other and both face the outside of the vehicle frame 1. The access opening is arranged on the opposite side of the storage space, which can enable the material taking device or the material taking personnel to have sufficient material taking space and can well avoid interference caused by material taking actions in different directions. As Figure 3 shown, the vehicle frame 1 includes four vertical pipes such as the first vertical pipe 11, the second vertical pipe 12, the third vertical pipe 13 and the fourth vertical pipe 14, and also includes a plurality of horizontal pipes such as the first short horizontal pipe 16, the third short horizontal pipe 17, the first long horizontal pipe 20 and the second long horizontal pipe 26. The plurality of horizontal pipes are divided into two layers. The horizontal pipes of each layer are connected and fixed to the vertical pipes through connecting buckles 15 to form a storage space. For example, the first short horizontal pipe 16, the second short horizontal pipe 18, the first long horizontal pipe 20 and the second long horizontal pipe 26 form a quadrilateral structure through the connecting buckle 15, and the third short horizontal pipe 17 is used to block materials to form an access opening on one side of the first short horizontal pipe 16 to ensure the stability of the vehicle frame 1.

[0032] Furthermore, the bottom of the storage space is inclined and gradually rises from the inner side to the side of the access opening. The access opening is on the side with a relatively higher position in the storage space, which is more in line with the ergonomic design and convenient for taking materials. When the relative position of the access opening side is relatively high, the relative position of the other side of the storage space is relatively low. Under the action of gravity, the materials will move to the side with a lower height of the storage space. Therefore, there are materials on both opposite sides of the vehicle frame 1, which can keep the vehicle frame 1 in good balance and avoid the problem of excessive concentration of materials on one side of the vehicle frame 1, taking into account the convenience of taking materials and the stability of the vehicle frame 1. A blocking member is provided on the side of the storage layer relative to the access opening. The blocking member is used to block the falling of materials, so that the materials are fixed on this side and no longer slide, maintaining stability during transportation. It should be noted that in this embodiment, the blocking member is the third short horizontal pipe 17. The two ends of the third short horizontal pipe 17 are also connected to the vertical pipe through the connecting buckle 15. The position of the third short horizontal pipe 17 is above the second short horizontal pipe 18, and the third short horizontal pipe 17 can also strengthen the structural strength of the vehicle frame 1; of course, a horizontal pipe on the same side as the third short horizontal pipe 17 can also be added to block the materials.

[0033] Whether it is manual or machine equipment to take materials, reducing the resistance when taking materials is beneficial to improving the efficiency of taking materials. A corresponding resistance reduction mechanism can be set on the storage layer, such as Figure 2 and Figure 4 As shown, in this embodiment, the storage layer includes several storage beams 2. The two ends of the storage beams 2 are connected to the vehicle frame 1. Three storage beams 2 are arranged in parallel and at intervals to form a storage plane. The number of storage beams 2 can be increased or decreased according to the actual situation. The storage beam 2 is provided with rolling members, and the rolling members are used to assist the materials to slide on the storage layer. Specifically, the storage beam 2 includes a beam body 23. A groove is provided on the storage surface of the beam body 23 along the length direction of the beam body 23, and several rolling members are arranged in the groove. The rolling member includes a roller 22 and a fixing pin 24. The fixing pin 24 penetrates the beam body 23, and the roller 22 is rotatably arranged around the fixing pin 24. In addition, the structures of the storage beam 2 and the rolling members can also adopt other styles. For example, multiple grooves are provided on the storage surface of the beam body 23 along the length direction of the beam body 23, and rolling members are arranged in each groove. The rolling member is a ball, and the rolling surface of the ball extends beyond the groove.

[0034] Such as Figure 1 and Figure 2As shown in the figure, a number of material boxes 3 can also be arranged on the storage layer. The bottom of the material box 3 is in contact with the rolling parts, and the material box 3 can slide on the rolling parts. When there is a material box 3 on the storage beam 2, the material box 3 will slide to the lower end of the storage layer on the plane formed by the tops of multiple rollers 22 due to its own gravity. When the material box 3 slides to the lower end of the storage beam 2, it will be blocked by the third short cross-tube 17 above the second short cross-tube 18, so that the material box 3 is stabilized at this position and no longer slides, ensuring the stability of the material box 3 during transportation. When it is necessary to take materials, the material box 3 is directly pulled out from the higher end of the storage layer. Under the rotation of the rollers 22, the extraction is labor-saving and fast, improving the production efficiency.

[0035] The storage beam 2 is connected to the vehicle frame 1 through a connecting part. The connecting part is mainly a buckle, which is arranged at both ends in the length direction of the beam body 23. In this embodiment, specifically, referring to Figure 5 Figure, first buckles 21 and second buckles 25 are arranged at both ends in the length direction of the beam body 23, and both the first buckles 21 and the second buckles 25 are connected to the vehicle frame 1. Among them, the structures of the first buckles 21 and the second buckles 25 are the same. Taking the first buckle 21 as an example, one end of the first buckle 21 is a connecting groove 211, and the other end is a rectangular hook 212. The connecting groove 211 is fixedly connected to the beam body 23 through a bolt, and the rectangular hook 212 is hooked on the cross-tube. In addition, there is a protrusion 213 inside the rectangular hook 212. When the rectangular hook 212 is hooked on the cross-tube, the protrusion 213 will be stuck under the cross-tube and clamped with the cross-tube to prevent the rectangular hook 212 from slipping out of the cross-tube.

[0036] The movement of the transfer trolley is inseparable from the moving parts. In this embodiment, as Figures 1 - 3 shown, a number of casters 19 are arranged at the bottom of the vehicle frame 1. The casters 19 are provided with wheel brakes 191 for braking the casters 19. Specifically, the bottoms of the first vertical pipe 11, the second vertical pipe 12, the third vertical pipe 13 and the fourth vertical pipe 14 are all connected with casters 19. The casters 19 are universal wheels, which are convenient for pushing the trolley to turn. The wheel brakes 191 are arranged on the casters 19. After the trolley is transported to the designated position, the operator steps on the wheel brakes 191 manually to fix the position of the trolley, which is convenient and practical.

[0037] Embodiment 2

[0038] On the basis of the first embodiment, the difference from the first embodiment is that a storage layer is arranged on the vehicle frame 1. Each storage layer includes two storage spaces, and the access openings of the storage spaces are arranged oppositely and both face the outside of the vehicle frame 1. That is, the access openings of each storage space are arranged on the left and right sides or the front and back sides of the vehicle frame 1.
