[0054] Please refer to the instruction manual Figure 1-Figure 7 The present invention provides a lithium battery recycling energy storage device, which mainly includes an energy storage platform 1, a top platform 2, a placement slot 3, a negative electrode contact plate 4, a positive electrode contact assembly 5, a clamping assembly 6, a clamping drive mechanism 7, a telescopic cylinder 9, a guide column 21 and a support 8. The specific structure and implementation method are as follows:

[0055] Overall structure of the device:

[0056] A top platform 2 is provided directly above the energy storage platform 1 , and the four corner ends between the energy storage platform 1 and the top platform 2 are connected by support pillars 8 to ensure the stability of the entire device.

[0057] The energy storage table 1 is provided with a placement slot 3 on the table top for placing a plurality of cylindrical lithium batteries to be stored.

[0058] Long strips of negative electrode contact plates 4 are provided on the left and right sides of the center of the bottom of the placement groove 3 for contacting the negative electrode of the lithium battery.

[0059] Positive contact assembly:

[0060] A telescopic cylinder 9 is installed at the center of the top platform 2, and the telescopic end of the telescopic cylinder 9 is connected to the positive contact component 5.

[0061] The positive contact assembly 5 specifically includes a crossbeam 51, an elastic connector 52 and a negative contact plate 53. The crossbeam 51 is connected to the telescopic end of the telescopic cylinder 9, and the negative contact plate 53 is distributed directly below the crossbeam 51.

[0062] The elastic connector 52 is connected between the crossbeam 51 and the negative contact plate 53. Specifically, it includes an elastic connector block 521 connected at the center between the crossbeam 51 and the negative contact plate 53, and tensioning springs 522 connected at the left and right ends of the crossbeam 51 and the negative contact plate 53. The elastic connector 52 allows the negative contact plate 53 to better contact the positive electrode of the lithium battery.

[0063] Clamping assembly:

[0064] The inner sides of the front and rear walls of the placement groove 3 are both provided with clamping components 6 for clamping a plurality of cylindrical lithium batteries to be stored.

[0065] The clamping assembly 6 specifically includes a side clamping plate 61 distributed horizontally and along the length direction of the placement slot 3, a plurality of clamping fins 62 evenly distributed from top to bottom on the clamping surface of the side clamping plate 61, and a plurality of arc-shaped clamping notches 63 evenly distributed from left to right on the inner side edge of each clamping fin 62.

[0066] The multiple clamping fins 62 in the clamping assembly 6 on one side and the multiple clamping fins 62 in the clamping assembly 6 on the other side are staggered up and down, and can be staggered when clamping smaller lithium batteries to avoid affecting the clamping effect due to mutual contact, and the inner arc surface of the arc-shaped clamping notch 63 is covered with a flexible material to avoid damage to the lithium battery and better clamp the lithium battery.

[0067] Clamping drive mechanism:

[0068] A clamping drive mechanism 7 for synchronously driving the clamping assemblies 6 on both sides is installed inside the center of the bottom of the placement groove 3.

[0069] The clamping drive mechanism 7 specifically comprises a dual-axis drive motor 71 located at the center of the bottom of the placement slot 3, a drive screw 72 connected to the front and rear output ends of the dual-axis drive motor 71, and a screw sleeve 73 threadedly mounted on the front and rear drive screws 72. The top walls of the front and rear screw sleeves 73 are connected to the center of the clamping assemblies 6 on either side. The dual-axis drive motor 71 drives the drive screw 72 to rotate, causing the screw sleeve 73 to move the clamping assemblies 6 toward or away from each other, thereby clamping or releasing the lithium battery.

[0070] Guide column:

[0071] Guide posts 21 are installed on the left and right ends of the top of the positive contact assembly 5. The guide posts 21 on both sides are slidably connected to the inside of the top platform 2 to ensure the stability and accuracy of the positive contact assembly 5 during the expansion and contraction process.

[0072] How it works

[0073] First, place several cylindrical lithium batteries to be stored in the placement slot 3 in sequence. Then, activate the dual-axis drive motor 71, causing the clamping assembly 6 to clamp the lithium batteries. Next, activate the telescopic cylinder 9, causing the negative contact plate 53 of the positive contact assembly 5 to contact the positive electrode of the lithium battery, while simultaneously bringing the negative electrode of the lithium battery into contact with the negative contact plate 4, thereby storing energy in the lithium battery. Once energy storage is complete, the telescopic cylinder 9 drives the positive contact assembly 5 to reset, and the dual-axis drive motor 71 drives the clamping assembly 6 to release the lithium battery, allowing the stored lithium battery to be removed.
