Description

Technical Field

[0001] The present application relates to the technical field of production equipment for energy storage devices, and particularly relates to a hanging battery pack propulsion device and a battery pack box loading equipment. Background Art

[0002] For the purpose of systematic management of battery packs, generally, battery packs are centrally stored in containers. To improve the box loading efficiency, usually, after a bearing component of a propulsion mechanism bears a battery pack, the battery pack is pushed into the container by a pusher component of the propulsion mechanism.

[0003] The existing propulsion mechanisms generally move the propulsion mechanism to the empty space of the container in the vertical and horizontal directions through a sliding module and a lifting mechanism. Due to the large weight of the battery pack, in order to reduce the component wear of the propulsion mechanism, the existing sliding module is arranged below the propulsion mechanism and bears the propulsion mechanism and the battery pack. However, this results in relevant components still existing below the propulsion mechanism. Therefore, the lowest position that the propulsion mechanism can descend to is higher than the lowest row of empty spaces in the container, and manual loading of battery packs is required for the lowest row of empty spaces in the container, which has the problem of cumbersome operation. Summary of the Utility Model

[0058] To make the above objects, features, and advantages of the present application more apparent and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0059] For the purpose of systematic management of battery packs, generally, battery packs are centrally stored in a container. To improve the packing efficiency, usually, after the battery packs are carried by the carrying component of the pushing mechanism, the battery packs are pushed into the container by the pushing component of the pushing mechanism.

[0060] The existing pushing mechanism generally moves the pushing mechanism to the empty space of the container in the vertical and horizontal directions through a sliding module and a lifting mechanism. Since the battery packs are heavy, in order to reduce the wear of the components of the pushing mechanism, the existing sliding module is arranged below the pushing mechanism and carries the pushing mechanism and the battery packs. However, this results in relevant components below the pushing mechanism. Therefore, the lowest position that the pushing mechanism can descend to is higher than the lowest row of empty spaces in the container, and manual loading of battery packs is required for the lowest row of empty spaces in the container, which has the problem of cumbersome operation.

[0061] Therefore, the present application proposes a hanging type battery pack pushing device. Please refer to Figure 1 As shown, a hanging type battery pack pushing device proposed in an embodiment of the present application includes a base 10, a first driving component 20, two sets of carrying components 30 arranged in parallel, a second driving component 40, and a pushing component 50. The upper surface of the base 10 is configured to install and fix the driving end of a transfer mechanism (not shown in the figure). The hanging type battery pack pushing device moves to a predetermined position under the drive of the transfer mechanism; the two sets of carrying components 30 are arranged on the base 10 so as to be close to or away from each other along a first direction ( Figure 1 the X direction in Figure 1 ), and the carrying ends of the two sets of carrying components 30 for carrying the battery packs are located below the base 10. The driving end of the first driving component 20 is connected to the two sets of carrying components 30 or one of the two sets of carrying components 30; the first driving component 20 is configured to drive the carrying ends of the two sets of carrying components 30 to separate along the first direction, so that the battery packs can enter the carrying surfaces of the carrying ends of the two sets of carrying components 30 along a second direction ( Figure 1 the Y direction in

[0062] ), and the second direction is perpendicular to the first direction; the first driving component 20 is further configured to drive the two sets of carrying components 30 to approach along the first direction, so as to support and clamp the two opposite sides of the lower surface of the battery pack extending along the second direction through the carrying ends of the two sets of carrying components 30; the pushing component 50 is slidably installed on the lower surface of the base 10 along the second direction. The driving end of the second driving component 40 is connected to the pushing component 50, and the second driving component 40 is configured to drive the pushing component 50 to reciprocate along the second direction, so as to push the battery packs supported and clamped by the carrying ends of the two sets of carrying components 30 into the empty spaces of the container.

[0062] Specifically, the transfer mechanism can be a robot or a multi-axis linear module.

[0063] In the suspension type battery pack propulsion device proposed in this application, by arranging the bearing ends of two sets of bearing components 30 below the base 10 and connecting the upper surface of the base 10 to the driving end of the transfer mechanism, the suspension type assembly of the bearing components 30 is realized, increasing the maximum descending stroke of the bearing components 30. When packing the battery pack into the container, the bearing components 30 can descend to the lowest row of empty spaces in the container, realizing automatic packing of the lowest row of empty spaces in the container and improving the packing efficiency of the battery pack. At the same time, the distance between the two sets of bearing components 30 is adjustable, and it can also adapt to various battery packs of different sizes, with good compatibility.

[0064] Please refer to Figures 1 to 3 As shown in the figure, as an implementation manner, the bearing component 30 includes a moving member 31, a suspension member 32, and a bearing member 33. The moving member 31 is installed on the upper surface of the base 10 so as to be reciprocally movable in the first direction. The driving end of the first driving component 20 is connected to the moving members 31 of two sets of bearing components 30 or the moving member 31 of any one set of bearing components 30. The first end of the suspension member 32 is fixedly installed on the moving member 31, the second end of the suspension member 32 extends downward toward the base 10, and the bearing member 33 is installed at the second end of the suspension member 32 and extends in the second direction.

[0065] Specifically, a connecting portion 11 is provided at the center of the upper surface of the base 10, and the base 10 is installed on the driving end of the transfer mechanism through the connecting portion 11.

[0066] Specifically, the first driving component 20 includes two first cylinders 200. Each first cylinder 200 corresponds to one set of bearing components 30. The fixed end of the first cylinder 200 is installed on the base 10, and the driving end of the first cylinder 200 is connected to the moving member 31 of the corresponding bearing component 30.

[0067] Specifically, the moving member 31 is slidably installed on the base 10 through a plurality of sets of sliding guide pairs 34 to ensure the stability and reliability of the movement of the moving member 31 in the first direction. Each set of sliding guide pairs 34 includes a linear guide rail and a slider. The linear guide rail is fixedly installed on the moving member 31 and extends in the first direction, and the slider is fixed on the base 10 and can be slidably sleeved on the linear guide rail.

[0068] Specifically, the suspension member 32 includes a plurality of suspension rib plates 320 arranged at intervals in the second direction. The first end of each suspension rib plate 320 is fixedly installed on the moving member 31, and the bearing member 33 is fixedly installed at the second ends of all the suspension rib plates 320. On the premise of ensuring the overall strength of the suspension member 32, a weight reduction design is carried out on the suspension member 32, reducing the weight of the suspension member 32.

[0069] Through the cooperation of the moving member 31, the suspension member 32 and the bearing member 33, a bearing assembly 30 with a simple structure, low cost and good stability and reliability is provided.

[0070] As an implementation manner, the bearing member 33 includes a bearing frame 330 and a plurality of groups of load-bearing wheels 331. The plurality of groups of load-bearing wheels 331 are configured to rotate self-axis along an axis in the same direction as the first direction. The bearing frame 330 is installed inside the second end of the suspension member 32. Each load-bearing wheel 331 in each group of load-bearing wheels 331 is installed at intervals in the second direction on the bearing 330 frame. The plurality of groups of load-bearing wheels 331 are configured to bear one side of the lower surface of the battery pack extending in the second direction.

[0071] It can be seen that by installing a plurality of groups of load-bearing wheels 331 for bearing one side of the lower surface of the battery pack on the bearing frame 330, the friction between the bearing member 33 and the battery pack is greatly reduced, which is convenient for pushing the battery pack out of the bearing assembly 30, and at the same time, the wear of the bearing member 33 on the battery pack is also reduced.

[0072] As an implementation manner, the bearing member 33 further includes a first clamping member 332. The first clamping member 332 is installed on the bearing frame 330 and is located on the side of the plurality of groups of load-bearing wheels 331 close to the suspension member 32.

[0073] Specifically, the first clamping member 332 is at least one clamping plate vertically installed on the bearing frame 330.

[0074] By providing the first clamping member 332 on the bearing frame 330 and clamping the two outer side walls of the battery pack by the first clamping members 332 of two sets of bearing assemblies 30, the limit of the battery pack is realized, preventing the battery pack from shifting during the process of being pushed out of the bearing assembly 30.

The rotating shaft 43 is rotatably installed at one end of the base 10 away from the container. The motor 41 drives the rotating shaft 43 to rotate through the transmission assembly 42. The two driving sprockets 44 are installed at both ends of the rotating shaft 43 in the first direction. The two driven sprockets 45 are rotatably installed at one end of the base 10 close to the container. The two driven sprockets 45 correspond to the two driving sprockets 44 one by one. Each transmission chain 46 is sleeved on a driving sprocket 44 and a driven sprocket 45 on the same side. Both ends of the sliding seat 51 in the second direction are respectively connected to the two transmission chains 46.

[0080] Specifically, the transmission assembly 42 adopts a transmission pair composed of a chain and a sprocket.

[0081] By installing two first push rods 52 at intervals on the sliding seat 51, the second driving assembly 40 drives the sliding seat 51 to move in the second direction. The two first push rods 52 push the battery packs supported and clamped by the bearing ends of the two sets of bearing assemblies 30 into the vacant positions of the container, realizing the pushing out of the battery packs from the two sets of bearing assemblies 30. A pushing component 50 with a simple structure, easy to implement, low cost, and stable pushing is provided. At the same time, the third driving member 53 drives the two first push rods 52 to approach or move away from each other in the first direction, thereby adjusting the distance between the two first push rods 52 to adapt to battery packs of various different sizes, with good compatibility.

[0082] As an implementation manner, the pushing component 50 further includes two second push rods 54 extending in the second direction. The two second push rods 54 are installed on the sliding seat 51 at intervals in the first direction. The two second push rods 54 are located between the two first push rods 52, and the two second push rods 54 are configured to cooperate with the two first push rods 52 to jointly push the battery packs supported and clamped by the bearing ends of the two sets of bearing assemblies 30 into the vacant positions of the container.
