[0002] In the production process of power batteries, cell insertion is a crucial step, which involves installing the battery cells into the battery casing. The orientation of the cells may differ in different stages. For example, in the cell insertion process, the cells are generally inserted into the casing lying flat. After the cells are installed in the battery casing, the casing needs to be rotated at a certain angle, such as 90°, to make the battery casing stand upright before the top cover is sealed and welded to the battery casing.

[0003] Because of the gap between the top cover and the battery casing, the top cover is prone to shifting when the battery casing is flipped or reversed, resulting in low positioning accuracy. Utility Model Content

[0053] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0054] Please see Figure 1 and Figure 2 The battery casing 100 flipping device provided in this application embodiment will now be described. The battery casing 100 flipping device provided in this application embodiment is used to flip the battery casing 100 after the battery cell is inserted into the casing. The battery casing 100 can be a square battery casing 100. The battery casing 100 contains a battery cell (not shown in the figure), and a top cover 200 is connected to one side of the battery cell.

[0055] The battery casing 100 flipping device provided in this application embodiment includes a rotation drive mechanism 20, a clamping mechanism 30, a snap-fit ​​assembly 41, a first drive assembly 42, and a pressing member 43.

[0056] The clamping mechanism 30 is used to clamp the battery casing 100. The rotary drive mechanism 20 drives the clamping mechanism 30 to flip.

[0057] like Figure 1 and Figure 8 As shown, the snap-fit ​​assembly 41 is at least partially located between the battery housing 100 and the top cover 200, and the clamping member 43 is located on the side of the top cover 200 away from the battery housing 100. The first drive assembly 42 drives the clamping member 43 to move toward the top cover 200 so that the top cover 200 is pressed against the snap-fit ​​assembly 41.

[0058] Since a certain distance needs to be maintained between the top cover 200 and the battery casing 100 after the battery cell is installed, a snap-fit ​​assembly 41 is provided to ensure that the top cover 200 abuts against the snap-fit ​​assembly 41, thus keeping the top cover 200 separated from the battery casing 100. Furthermore, by providing a first drive assembly 42 to drive the clamping member 43 to move towards the top cover 200, the top cover 200 can be pressed firmly against the snap-fit ​​assembly 41, preventing the top cover 200 from shifting during rotation and thereby improving positioning accuracy.

[0059] The battery casing flipping device provided in this application embodiment clamps the battery casing 100 with a clamping mechanism 30 and drives the clamping mechanism 30 to flip using a rotation drive mechanism 20, thereby realizing the reversal of the battery casing 100. The snap-fit ​​component 41 is at least partially located between the battery casing 100 and the top cover 200, and the pressing member 43 is located on the side of the top cover 200 away from the battery casing 100. The pressing member 43 is driven by the first drive component 42 to move toward the top cover 200, thereby pressing the top cover 200 onto the snap-fit ​​component 41, preventing the top cover 200 from shifting during rotation, thereby improving positioning accuracy.

[0060] Please see Figure 6 and Figure 7 The snap-fit ​​assembly 41 may include a mounting member 411, a latch 412, and a first elastic member 413. The mounting member 411 is disposed on the clamping mechanism 30. The latch 412 is disposed on the mounting member 411, and one end of the latch 412 extends out of the mounting member 411 to support the top cover 200.

[0061] One end of the first elastic member 413 elastically abuts against the mounting member 411, and the other end elastically abuts against the other end of the latch 412.

[0062] The first elastic element 413 allows the latch 412 to extend and retract elastically. When it is necessary to clamp the battery housing 100, the clamping mechanism 30 clamps the battery housing 100, and under the squeezing action of the top cover 200, the latch 412 overcomes the elastic force of the first elastic element 413 and retracts the mounting member 411, allowing the top cover 200 to pass through. After the top cover 200 passes through, under the action of the first elastic element 413, the latch 412 extends and supports the top cover 200.

[0063] Please see Figure 6 and Figure 7 The mounting component 411 may have a receiving groove 4111. The latch 412 is received in the receiving groove 4111, with one end of the latch 412 extending out of the receiving groove 4111, thereby allowing the latch 412 to...

[0064] Please see Figure 1The clamping mechanism 30 may include a rotating base 10, a second driving component and two clamping components 31. The rotating driving mechanism 20 drives the rotating base 10 to flip. The second driving component is disposed on the rotating base 10. The second driving component is respectively connected to the two clamping components 31 to drive the two clamping components 31 to move in a direction that approaches each other to clamp the battery housing 100.

[0065] The battery housing 100 is clamped by driving the two clamping components 31 closer together via the second drive component. When it is necessary to release the battery housing 100, the second drive component drives the two clamping components 31 away from each other. Specifically, the second drive component can be a cylinder.

[0066] Please see Figure 3 The clamping assembly 31 may include a mounting base 311, a clamping member 312, and an elastic buffer assembly 313. A second drive assembly is drively connected to the mounting base 311. The clamping member 312 is disposed on the mounting base 311. The elastic buffer assembly 313 is disposed on the mounting base 311 and elastically abuts against the clamping member 312, allowing the clamping member 312 to elastically extend and retract relative to the mounting base 311 in a first direction.

[0067] Please refer to Figure 1 The “first direction” can be represented by the Y-axis, the “second direction” can be represented by the Z-axis, and the “direction in which the two clamping components move closer to each other” can be represented by the X-axis.

[0068] When the clamping member 312 collides with the battery casing 100, the clamping member 312 can overcome the elastic force of the elastic buffer component 313 and retract along the first direction, thereby avoiding a hard collision between the clamping member 312 and the battery casing 100 and preventing damage to the clamping member 312 and the battery casing 100.

[0069] Please see Figures 3 to 5The mounting base 311 may have a mounting groove 3111. The elastic buffer assembly 313 may include a second elastic element 3131, a guide element 3132, and a connecting element 3133. The guide element 3132 is disposed within the mounting groove 3111, and the second elastic element 3131 is sleeved outside the guide element 3132. One end of the second elastic element 3131 abuts against the groove wall of the mounting groove 3111. One end of the connecting element 3133 extends into the mounting groove 3111 and abuts against the other end of the second elastic element 3131. The other end of the connecting element 3133 is connected to the clamping element 312. The guide element 3132 serves to guide the movement and prevent the second elastic element 3131 from shifting. One end of the connector 3133 abuts against the other end of the second elastic member 3131, and the other end of the connector 3133 is connected to the clamping member 312. When the clamping member 312 collides with the battery casing 100, the clamping member 312 overcomes the elastic force of the second elastic member 3131 and retracts in a third direction, thereby avoiding a hard collision between the clamping member 312 and the battery casing 100 and preventing damage to the clamping member 312 and the battery casing 100.

[0070] Please see Figure 5 The clamping assembly 31 may further include a first guide rail 314 and a first slider 315 slidably mounted on the first guide rail 314. The first guide rail 314 is disposed on the mounting base 311, and the first slider 315 is connected to the clamping member 312. Through the cooperation of the first guide rail 314 and the first slider 315, a limiting and guiding function can be achieved to prevent the clamping member 312 from deviating in the direction of movement, thereby further improving the accuracy of movement.

[0071] Please see Figure 4 The mounting base 311 may be equipped with a sensor 3112, and the clamping member 312 is equipped with a sensor 3121. When the clamping member 312 moves to a preset position along the first direction, the sensor 3121 can trigger the sensor 3112 to generate a sensing signal. Through the cooperation of the sensor 3112 and the sensor 3121, the clamping member 312 can be triggered to generate a sensing signal when it moves to the preset position along the first direction, thereby timely controlling the clamping member 312 to stop operating and avoiding hard collision between the clamping member 312 and the battery casing 100.

[0072] Please see Figure 4 and Figure 5The clamping member 312 may include a clamping block 3122, a first limiting block 3123, and a second limiting block 3124. The clamping block 3122 is disposed on the mounting base 311. The first limiting block 3123 and the second limiting block 3124 are spaced apart on the clamping block 3122 along a first direction, forming a limiting guide groove 3125. One side of the battery housing 100 is accommodated in the limiting guide groove 3125 of one of the clamping components 31, and the other side of the battery housing 100 is accommodated in the limiting guide groove 3125 of the other clamping component 31. The limiting guide groove 3125 provides a limiting and guiding function for the battery housing 100, preventing the battery housing 100 from shifting.

[0073] Please see Figure 1 The clamping mechanism 30 may further include a second guide rail 32 and a second slider 33 slidably mounted on the second guide rail 32. The second guide rail 32 is disposed on the rotary seat 10, and the second slider 33 is connected to the clamping assembly 31. Through the cooperation of the second guide rail 32 and the second slider 33, a limiting and guiding function can be achieved to prevent the clamping assembly 31 from shifting during clamping, thereby further improving the positioning accuracy.

[0074] Please see Figure 9 The battery casing 100 flipping device may further include a mounting frame 50, a movable frame 60, a third drive assembly 70, a lifting frame 80, and a fourth drive assembly 90. The movable frame 60 is movably mounted on the mounting frame 50 along a first direction. The third drive assembly 70 is drively connected to the movable frame 60 to drive the movable frame 60 to move along the first direction. The lifting frame 80 is movably mounted on the movable frame 60 along a second direction. The fourth drive assembly 90 is drively connected to the lifting frame 80 to drive the lifting frame 80 to move along the second direction. A rotary drive mechanism 20 is mounted on the lifting frame 80.

[0075] By cooperating with the movable frame 60 and the third drive component 70, as well as the lifting frame 80 and the fourth drive component 90, the battery casing 100 can be moved simultaneously. Compared with the existing technology that requires additional handling robots, the embodiment of this application has both handling functions, the structure is simpler and more compact, and it can avoid the problems of low positioning accuracy and low efficiency caused by multiple handling.

[0076] The second direction is set at an angle to the first direction. For example, it can be 90°, or it can be set to other angles as needed.

[0077] The operation of the battery casing 100 flipping device according to one embodiment of this application is as follows:

[0078] First, the third drive assembly 70 drives the movable frame 60 to move along the first direction, causing the clamping mechanism 30 to move above the battery housing 100;

[0079] Next, the fourth drive assembly 90 drives the lifting frame 80 to descend to the designated position along the second direction;

[0080] Then, the clamping mechanism 30 clamps the battery housing 100 and drives the pressing member 43 to move toward the top cover 200 by setting the first driving component 42, thereby pressing the top cover 200 onto the snap-fit ​​component 41.

[0081] Then, the rotary drive mechanism 20 drives the clamping mechanism 30 to flip, thereby realizing the reversing operation of the battery casing 100;

[0082] Finally, the fourth drive assembly 90 drives the lifting frame 80 to rise, and the third drive assembly 70 drives the movable frame 60 to move along the first direction, thereby moving the battery casing 100 to the next work station along the first direction.

[0083] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
