[0002] In order to facilitate the transportation and centralized management of energy storage battery packs, the battery packs are stacked in containers or energy storage cabinets. The battery packs are usually loaded into the container by a loading device. The existing loading device generally first moves the propulsion mechanism carrying the battery pack to the empty space of the container through a transfer mechanism, and then the propulsion mechanism pushes the battery pack in the tooling into the empty space in the container.

[0003] The existing propulsion mechanism includes a carrying mechanism and a pushing assembly. The battery pack is loaded into the carrying mechanism in two ways: an external assembly pushes the battery pack into the carrying mechanism, or the pushing assembly of the propulsion mechanism pulls the battery pack into the carrying mechanism. Since the battery pack is heavy and easily bumped, the above methods can only push or pull the battery pack slowly, resulting in low efficiency in moving the battery pack. Utility Model Content

[0052] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0053] In order to facilitate the transportation and centralized management of energy storage battery packs, the battery packs are stacked in containers or energy storage cabinets. The battery packs are usually loaded into the container by a loading device. The existing loading device generally first moves the propulsion mechanism carrying the battery pack to the empty space of the container through a transfer mechanism, and then the propulsion mechanism pushes the battery pack in the tooling into the empty space in the container.

[0054] The existing propulsion mechanism includes a carrying mechanism and a pushing assembly. The battery pack is loaded into the carrying mechanism in two ways: an external assembly pushes the battery pack into the carrying mechanism, or the pushing assembly of the propulsion mechanism pulls the battery pack into the carrying mechanism. Since the battery pack is heavy and easily bumped, the above methods can only push or pull the battery pack slowly, resulting in low efficiency in moving the battery pack.

[0055] Therefore, this application proposes a battery pack boxing device, please refer to Figure 1 As shown, a battery pack boxing device proposed in an embodiment of the present application includes a conveying mechanism 10, a transfer mechanism 20, a bearing mechanism 30 and a pushing mechanism 40. A loading station is arranged on the conveying path of the conveying mechanism 20. The conveying mechanism 20 is configured to convey the battery pack 50 to the loading station and lift the battery pack 50 at the loading station to a material taking position, so that both sides of the battery pack 50 in the length direction are suspended; the driving end of the transfer mechanism 20 is connected to the bearing mechanism 30, and the bearing mechanism 30 includes two bearing members 31 arranged in parallel and spaced apart. The transfer mechanism 20 is configured to drive the bearing mechanism 30 so that the first end of the bearing mechanism 30 is lifted along the water The transfer mechanism 20 moves in a horizontal direction toward the battery pack 50 at the material picking position, so that the two supporting members 31 are respectively located below the two side edges in the length direction of the suspended battery pack 50; the transfer mechanism 20 is also configured to lift the supporting mechanism 30 and respectively support the two side edges in the length direction of the battery pack 50 through the two supporting members 31, so that the battery pack 50 is separated from the conveying mechanism 10; the transfer mechanism 20 is also configured to drive the supporting mechanism 30 and the battery pack 50 to move to a position facing the outside of the empty space of the box, and the pushing mechanism 40 is arranged on the second end of the supporting mechanism 20, and the pushing mechanism 40 is configured to push the battery pack 50 in the supporting mechanism 30 into the empty space of the box.

[0056] It can be seen that the battery pack boxing device proposed in the present application realizes automatic loading of the battery pack 50 into the container or energy storage cabinet through the cooperation of the conveying mechanism 10, the transfer mechanism 20, the bearing mechanism 30 and the pushing mechanism 40, which has high loading efficiency and saves manpower. At the same time, through the cooperation of the transfer mechanism 20 and the bearing mechanism 30, the battery pack 50 to be put into the box is picked up by the sleeve method, which not only simplifies the overall structure of the battery pack boxing device; and in the process of the bearing mechanism 30 sleeves the battery pack 50 to be put into the box, the bearing mechanism 30 can quickly move to sleeve the battery pack 50, and the battery pack 50 does not need to move, which greatly reduces the probability of collision between the battery pack 50 and the bearing mechanism 30, and also improves the efficiency of picking up the battery pack 50, meeting the fast-beat packing requirements.

[0057] See also Figure 1 and Figure 4As shown, as an embodiment, the supporting mechanism 30 also includes a support plate 32, both ends of the support plate 32 are respectively fixed on the second end of a supporting member 31 in the length direction, and a first limiting member 33 is provided on the support plate 32.

In addition, after the battery pack 50 enters the carrying mechanism 30, it will eventually abut against the two limiting blocks 330, ensuring that the position of the battery pack 50 in the carrying mechanism 30 is uniform each time. Photoelectric sensors can also be provided on both sides of the two limiting blocks 330 to determine that the battery pack 50 has entered the carrying mechanism 30, so as to facilitate the control module to accurately control the operation of each component.

[0060] As an embodiment, the first ends of the two supporting members 31 are respectively provided with a second limiting member 34 and a cylinder 35; the cylinder 35 is configured to drive the second limiting member 34 to rise in the vertical direction to limit the battery pack 50 from detaching from the supporting mechanism 30 from the first end of the supporting member 31; the cylinder 35 is also configured to drive the second limiting member 34 to descend in the vertical direction to avoid the movement path of the battery pack 50 passing through the first end of the supporting member 31.

[0066] See also Figures 2 to 4 As shown, as an embodiment, the pushing mechanism 40 includes a first driving member 41, two sliding seats 42 and two pushing members 43.

[0067] Specifically, a connecting plate 44 is fixedly arranged between the two sliding seats 42 to enable the two sliding seats 42 to move synchronously. The two sliding seats 42 are connected as one by the connecting plate 44, so that the synchronous movement of the two sliding seats 42 is achieved, and the stability of the structure is enhanced.

[0068] Specifically, the first driving member 41 includes a motor 410, a transmission assembly, a rotating shaft 411, two driving sprockets 412, two driven sprockets 413 and two transmission chains 414. The motor 410 is installed on the top frame 36, and the rotating shaft 411 is rotatably installed at the first end of the top frame 36 in the length direction. The motor 410 drives the rotating shaft 411 to rotate through the transmission assembly. The two driving sprockets 412 are respectively installed at both ends of the rotating shaft 411, and the two driven sprockets 413 are rotatably installed at the second end of the top frame 36 in the length direction.

[0069] Specifically, the transmission assembly adopts a transmission pair consisting of a chain and a sprocket.

[0070] It can be seen that by installing a pushing member 43 on each of the two sliding seats 42, the first driving member 41 drives the two sliding seats 42 to move along the length direction of the top frame 36, thereby realizing pushing the battery pack 50 out from the supporting mechanism 30, providing a pushing mechanism 40 with a simple structure, easy implementation, low cost, and smooth pushing.

[0072] By providing two sets of pulling components 45, when the battery pack 50 is pushed out of the supporting mechanism 30, when the battery pack 50 is stuck in the supporting mechanism 30, the two sets of pulling components 45 pull the battery pack 50 back to correct the position of the battery pack 50, and then the pushing mechanism 40 pushes the battery pack 50 out of the supporting mechanism 30 again, thereby improving the efficiency of putting the battery pack 50 into the box.

[0074] Specifically, the second driving member 450 is a cylinder, a positioning groove is provided on the positioning member, and the material pulling member 451 is buckled in the positioning groove.

[0075] Through the cooperation between the second driving member 450 and the material pulling member 451 , it is achieved that the first end of the material pulling member 451 is always buckled on the corresponding positioning member to ensure the stability and reliability of the material pulling.

[0078] By installing the first detection member 430 at the end of the pushing member 43, automatic detection of the thrust applied by the pushing member 43 to the battery pack 50 is achieved. If the thrust is greater than a preset range, it is determined that the battery pack 50 is stuck on the supporting mechanism 30, and the pushing member 43 is controlled to stop pushing the battery pack 50 to avoid damage to the battery pack 50.

[0083] Specifically, the third driving member 110 is a cylinder or other forms of linear lifting modules, and the width of the support member 111 is smaller than the width of the battery pack 50, so that after the support member 111 lifts the battery pack 50, both sides of the battery pack 50 in the length direction are suspended.

[0084] It can be seen that by arranging the third driving member 110 and the supporting member 111 at the loading station, and through the cooperation of the third driving member 110 and the supporting member 111, the battery pack 50 to be put into the box at the loading station can be automatically lifted to the material taking position, so that the two opposite sides of the battery pack 50 are suspended in the air, which is convenient for the supporting mechanism 30 to take the battery pack 50 at the material taking position, thereby improving the efficiency of putting the battery pack 50 into the box.

The first conveyor portion 140 and the second conveyor portion 141 are respectively configured to convey and support two sides of the battery pack 50 in the length direction.

[0087] When the second conveyor line 14 receives the battery pack 50 after reversing conveyed by the reversing assembly 13, the third driving member 110 drives the supporting member 111 to descend to a low position (lower than the conveying surface of the first conveying part 140 and the second conveying part 141) to avoid the second conveyor line 14 receiving the battery pack 50;

[0088] After the second conveyor line 14 conveys the received battery pack 50 to the loading station, the third driving member 110 drives the support member 111 to rise to a high position (higher than the conveying surface of the first conveying part 140 and the second conveying part 141), and lifts the battery pack 50 at the loading station to the material picking position through the support member 111.

[0089] Specifically, the first conveying unit 140 and the second conveying unit 141 are any one of belt-type, chain-plate-type or roller-type conveying mechanisms.

[0090] Specifically, the reversing assembly 13 rotates the received battery pack 50 by 90° and then conveys it to the second conveying line 14 .

[0091] Through the cooperation of the first conveyor line 12, the reversing assembly 13 and the second conveyor line 14, the processed battery pack 50 is automatically reversed and then conveyed to the loading station, providing a conveying mechanism 10 that can meet the application scenario of battery pack reversal.

[0092] See also Figure 1 As shown, the specific packing process of the battery pack boxing device proposed in the embodiment of the present application is as follows:

[0093] The conveying mechanism 10 conveys the battery pack 50 to be boxed to the loading station;

[0094] The third driving member 110 drives the supporting member 111 to rise, and lifts the battery pack 50 at the loading station to the material taking position, so that both sides of the battery pack 50 in the length direction are suspended in the air;

[0095] The transfer mechanism 20 drives the carrying mechanism 30 to move, so that the first end of the carrying mechanism 30 moves horizontally toward the battery pack 50 at the material taking position, so that the two carrying members 31 are respectively located below the two side edges of the suspended length direction of the battery pack 50;

[0096] The transfer mechanism 20 lifts the carrying mechanism 30 and carries the two sides of the battery pack 50 in the length direction through the two carrying members 31, so that the battery pack 50 is separated from the conveying mechanism 10, and the battery pack 50 is restricted in the carrying mechanism 30 through the first limiting member 33 and the second limiting member 34;

[0097] The transfer mechanism 20 then drives the carrying mechanism 30 and the battery pack 50 to move to a position facing the outside of the empty space of the box;

[0098] The battery pack 50 in the supporting mechanism 30 is pushed into the empty space of the box by the pushing mechanism 40 .

[0099] The battery pack boxing device proposed in the embodiment of the present application has the following advantages:

[0100] 1) The battery packs to be boxed are picked up by a sleeve method, which not only simplifies the overall structure of the battery pack boxing device; the carrying mechanism can quickly move to take out the battery pack without moving the battery pack, which greatly reduces the probability of collision between the battery pack and the carrying mechanism, improves the efficiency of picking up the battery pack, and meets the fast-beat boxing requirements;

[0101] 2) The cooperation between the first limiting member and the second limiting member can limit the battery pack in the carrying mechanism, thereby preventing the battery pack from slipping out of the carrying mechanism during the transfer process, thereby improving the safety of the box-entering device;

[0102] 3) The pulling assembly can pull the battery pack back toward the carrying mechanism to correct the position of the battery pack, and can automatically handle the battery pack stuck in the carrying mechanism, thereby improving the packing efficiency of the battery pack;

[0103] 4) The push mechanism has a pressure detection function to avoid damage to the battery pack.

[0104] The above embodiments are only to illustrate the basic principles and characteristics of the present application. The present application is not limited by the above examples. Without departing from the spirit and scope of the present application, the present application may be subject to various changes and modifications, which are within the scope of the present application to be protected. The scope of protection claimed in the present application is defined by the attached claims and their equivalents.
