[0002] An energy storage container is a highly integrated energy storage device that contains multiple energy storage battery packs. Usually, multiple slots or brackets for installing energy storage battery packs are set in the container. The battery packs can be put into the box by aligning the battery packs with the slots and pushing them horizontally. In the existing energy storage industry, battery packs are usually transported by forklifts because they are heavy. Through manual alignment and with the help of auxiliary tools, the battery packs are pushed into the battery cluster or the bracket of the container.

Finally, during the manual boxing process, friction occurs between the battery pack and the bracket, and the appearance of the battery pack cannot be guaranteed to be undamaged. There is room for improvement, so a battery pack automatic clustering mechanism is proposed to solve the above problems. Utility Model Content

[0045] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0046] See also Figure 1-7 The utility model discloses a battery pack automatic clustering mechanism, comprising:

[0047] The clamping mechanism 1 is used to clamp the battery module 01 on both sides;

[0048] The pushing mechanism 2 is used for horizontally pushing one end of the battery module 01 clamped in the clamping mechanism into a box or a cluster;

[0049] The stabilizing mechanism 3 is used to keep the posture of the battery module 01 stable during the pushing process of the pushing mechanism 2.

[0050] The battery module box-entry mechanism proposed in the present application is used for the lateral box-entry transfer of power battery modules or other square module structures whose outer packaging is easily damaged.

[0051] The specific implementation method is that the battery module 01 is clamped by the clamping mechanism 1, and then transferred to the side of the surface where the battery module 01 needs to be placed, and then the battery module 01 is pushed horizontally to the placement surface by the pushing mechanism 2. During the pushing process, the stabilizing mechanism 3 presses down the end of the battery module 01 away from the pushing direction to maintain its horizontal state, to prevent its center of gravity from losing support and tilting as a whole, causing premature contact and wear with the placement surface. There is a certain height difference between the battery module 01 and the placement surface to ensure that it does not contact the placement surface during the pushing process.

[0052] In the present application, during the pushing process of the battery module 01, the stabilizing mechanism 3 keeps the posture of the battery module 01 stable by locking the end of the battery module 01 away from the pushing direction, thereby preventing the center of gravity from losing support and the entire module from tilting and wearing out in advance from contacting with the placement surface.

[0053] In one embodiment, the stabilizing mechanism 3 includes a fourth power unit 31, a connecting rod assembly 32 and a locking structure 33; the fourth power unit 31 is used to drive the locking structure 33 to press down one side of the battery module 01 through the connecting rod assembly 32 to prevent the battery module 01 from tilting to the other side, and the connecting rod assembly 32 is hinged to the output end of the fourth power unit 31 and the locking structure 33 respectively. The fourth power unit 31 is used to drive the connecting rod assembly 32 to rotate and drive the locking structure 33 to rotate and press down on the battery module 01.

[0054] Wherein, the connecting rod assembly 32 includes a hinge seat 321;

[0055] The locking structure 33 includes a connecting rod 331 and a pressing rod 332 disposed at the end of the connecting rod 331. A bearing pad 333 is disposed at the end of the pressing rod 332. The connecting rod 331 and the pressing rod 332 are combined into an L shape. The bearing pad 333 is a flexible gasket, which is used to make flexible contact between it and the battery module 01 to avoid damaging the battery module 01 during the pressing process.

[0056] One end of the connecting rod 331 away from the pressing rod 332 is hinged to the hinge seat 321;

[0057] The hinge seat 321 and the connecting rod 331 are both provided with hinge plates 322, wherein the hinge plate 322 on the connecting rod 331 is arranged at the center thereof, and two groups of hinge plates 322 are hinged to each other at one end away from the hinge seat 321 and the connecting rod 331, and the intersection of the two groups of hinge plates 322 is hinged to the output end of the fourth power unit 31.

[0058] When the above structure is in use, the fourth power unit 31 is running, and its output end pushes the intersection of the two sets of hinge pieces 322 and drives the two sets of hinge pieces 322 to rotate. When the hinge piece 322 on the connecting rod 331 rotates, it can drive the connecting rod 331 to rotate and press down with the connection point between it and the hinge seat 321 as the center, so as to lock the battery module 01;

[0059] When the fourth power unit 31 is running and drives its output end to contract, the output end pulls the intersection of the two sets of hinge plates 322 and also drives the two sets of hinge plates 322 to rotate. When the hinge plate 322 on the connecting rod 331 rotates, it can drive the connecting rod 331 to rotate and flip upward with the connection between it and the hinge seat 321 as the center, thereby unlocking the battery module 01. In the above process, the fourth power unit 31 is tilted as a whole and is in a contracted state, wherein the fourth power unit 31 is movably arranged on the pushing mechanism 2.

[0060] like Figure 1 , Figure 4 and Figure 5 As shown in , the pushing direction of the pushing mechanism 3 is perpendicular to the clamping direction of the clamping mechanism 1, and the pushing mechanism 3 acts on one end of the battery module;

[0061] The pushing mechanism 3 includes a push plate assembly 21 for contacting the battery module and a second power unit 22 for driving the push plate assembly to operate. The number of the stabilizing mechanism 3 is two groups;

[0062] A hinged frame for accommodating the stabilizing mechanism 3 is provided on the side of the push plate assembly 21 away from the battery module 01. The stabilizing mechanism 3 is symmetrically distributed on the push plate assembly 21. The fourth power unit 31 and the connecting rod assembly 32 are both arranged in the hinged frame. It should be added that the number of stabilizing mechanisms 3 can be appropriately increased according to the weight of the transfer target object to avoid the inability to prevent tilting due to excessive weight.

[0063] In another embodiment, if Fig. 9 As shown, the stabilizing mechanism 3 includes a fourth power unit 31 and a set of anti-rocking plates 35, and the output end of the fourth power unit 31 is provided with a transmission shaft 34 connected to the anti-rocking plates 35;

[0064] The anti-rocking plate 35 is provided with a missing portion 351 adapted to one end of the battery module 01, and the missing portion 351 is L-shaped, wherein the length of the anti-rocking plate 35 is consistent with the progressive length of the transmission shaft 34. In this embodiment, the fourth power unit 31 is arranged on the push plate assembly 21, and the push plate assembly 21 is provided with an extension groove corresponding to the anti-rocking plate 35. When the anti-rocking plate 35 is retracted, it can be completely stored on one side of the push plate assembly 21. When in use, the anti-rocking plate 35 can be extended to the outside of the push plate assembly 21 through the extension groove and act on the battery module 01;

[0065] The fourth power unit 31 pushes the anti-rock plate 35 to move laterally. The missing portion 351 on the anti-rock plate 35 is adapted to the battery module 01, so that when the anti-rock plate 35 is engaged with the battery module 01 under the push of the driving mechanism, the end of the battery module 01 is fixed to avoid tipping over due to loss of support of the center of gravity during the transfer process.

[0066] In another embodiment, if Fig.10 As shown, the stabilizing mechanism 3 includes a fourth power unit 31 disposed on one side of the push plate assembly 21, and a movable pressure plate 37 movably disposed on the other side of the push plate assembly 21;

[0067] An adjusting screw rod 36 which is transmission-connected to the fourth power unit 31 is disposed in the push plate assembly 21 , wherein one end of the movable pressure plate 37 extends into the push plate assembly 21 and is transmission-connected to the adjusting screw rod 36 .

[0068] When the above structure is in use, the fourth power unit 31 drives the adjusting screw 36 to rotate, and the adjusting screw 36 drives the movable pressure plate 37 to rise and fall, so as to fit with the battery module 01 and press down the battery module 01, thereby fixing the end of the battery module 01 and avoiding tipping over due to loss of support of the center of gravity during the transfer process.

[0069] It should be added that a flexible layer for contacting the battery module 01 is provided on the top of the movable pressure plate 37 , and the flexible layer is a rubber layer for reducing damage to the battery module 01 caused by the movable pressure plate 37 .

[0070] It should be further explained that the structure of the stabilizing mechanism 3 in the present application can be replaced by a structure that can achieve the same effect that can be easily thought of by technicians in the field, and is not limited to the two implementation schemes proposed in the present application.

[0071] like Figure 2 As shown, the clamping mechanism 1 includes a base frame 11, two sets of clamp assemblies 12 arranged opposite to each other, and a first power unit 13 for driving the clamp assemblies 12 to operate;

[0072] The two sets of clamp components 12 are arranged in an L shape opposite to each other, and are used to support the bottom of the battery module 01 and clamp the two sides of the battery module 01;

[0073] Rollers 121 are disposed on the side walls and the bottom of the clamp assembly 12 .

[0074] In the above structure, the base frame 11 is used to connect with a transfer robot or a robot arm in the prior art, and the robot drives the clamp assembly 12 to transfer between the grasping and warehousing process steps;

[0075] The two sets of clamp assemblies 12 are arranged in an L-shape relative to each other to ensure that the bottom of the battery module 01 can also be supported when clamping the two sides thereof;

[0076] The roller 121 is disposed on the clamp assembly 12 to reduce the friction force between the battery module 01 and the clamp assembly 12 during the pushing process of the battery module 01, so as to make the pushing process smoother and more stable.

[0077] like Figure 1 and Figure 4As shown, the pushing direction of the pushing mechanism 2 is perpendicular to the clamping direction of the clamping mechanism 1, and the pushing mechanism 2 acts on one end of the battery module 01;

[0078] The pushing mechanism 2 includes a push plate assembly 21 for contacting the battery module 01 and a second power unit 22 for driving the push plate assembly 21 to operate, wherein a contact layer may be added to the push plate assembly 21 as needed, and the contact layer is made of a flexible material such as silicone rubber, etc., to avoid the push plate assembly 21 from making hard contact with the battery module 01 during the pushing process, thereby causing damage to its surface.

[0079] like Figure 1 and Figure 5 As shown, it also includes a clamping mechanism 4 disposed in the base frame 11, and the clamping mechanism 4 is disposed between the two clamp assemblies 12 and vertically perpendicular to the battery module 01;

[0080] The pressing mechanism 4 includes a third power unit 41 and a pressing plate 42 arranged at the output end of the third power unit 41 . The pressing plate 42 is used to press down the battery module 01 to prevent it from sliding on the roller 121 .

[0081] The clamping mechanism 4 is used to press down the battery module 01 after the battery module 01 is clamped, so as to prevent the battery module 01 from sliding and deviating on the roller 121 in the clamp assembly 12 during the transfer process. When the battery module 01 is transferred to the container or near the battery cluster, the clamping mechanism 4 stops pressing down the battery module 01 to facilitate the subsequent operation of the pushing mechanism 2.

[0082] It should be noted that, during the process of preventing the tilting, the force borne by the stabilizing mechanism 3 gradually increases with the advancement of the battery module 01. To avoid damage to the battery module 01 during this process, when the pushing mechanism 2 is about to completely push the battery module 01 into the container, the stabilizing mechanism 3 is unlocked. At this time, the clamping mechanism 4 is pressed down to make the battery module 01 contact with the placement surface inside the container. The pushing mechanism 2 completes the final pushing process. On the premise of ensuring that the battery module 01 is not damaged during transfer, the friction path between the battery module 01 and the placement surface is minimized, thereby reducing the risk of damage to the surface of the battery module 01.

[0083] It is easy to think that Figure 1 As shown, the present application also includes a visual system 5, which includes a material taking visual positioning camera 51 and a box entry visual positioning camera 52 installed on the base frame 11;

[0084] The material picking visual positioning camera 51 is used to position the process of the clamping mechanism 1 clamping the battery module 01;

[0085] The box entry visual positioning camera 52 is used to position the battery module 01 when it is pushed into the box horizontally by the pushing mechanism 2.

[0086] In the present application, the first power unit 13 , the second power unit 22 , the third power unit 41 and the fourth power unit 31 are all servo motors or other driving devices that can accurately control the stroke and force.

[0087] This application also includes related structures such as a control system and a power supply system. Since these contents are commonly used technical means in this field, they are not explained and described in detail.
