[0028] The frame 1 is provided with a support 3; the support 3 is movably equipped with a clamping mechanism; the clamping mechanism includes a lifting plate 4 and a mounting plate 5; the lifting plate 4 is horizontally slidably provided with a first clamping rod 61 and a second clamping rod 62; the first clamping rod 61 and the second clamping rod 62 are movably mounted on the mounting plate 5; the mounting plate 5 is horizontally slidably provided with a first injection rod 71 and a second injection rod 72; the first clamping rod 61 and the second clamping rod 62 are respectively used to drive the first injection rod 71 and the second injection rod 72 to move; the first injection rod 71 and the second injection rod 72 are used to abut against the top surface of the battery casing 91; a flexible tube 73 is provided between the first injection rod 71 and the injection cavity 11 and between the second injection rod 72 and the injection cavity 11.
[0029] Specifically, in this embodiment, the graphene battery cell housing buffer device, during use, first places the battery casing 91 in the positioning groove 21 and on top of the piston plate 12, while simultaneously clamping the battery cell 92 between the first clamping rod 61 and the second clamping rod 62. Then, the lifting plate 4 is driven to descend, causing the mounting plate 5, the first liquid injection rod 71, and the second liquid injection rod 72 to move downwards. When the first liquid injection rod 71 and the second liquid injection rod 72 abut against the top surface of the battery casing 91, the liquid outlet of the first liquid injection rod 71... The outlets of the second injection rod 72 and the second injection rod 72 are both facing the inside of the battery casing 91. The lifting plate 4 continues to descend, thereby causing the lifting plate 4, the mounting plate 5, the battery cell 92, the battery casing 91 and the piston plate 12 to move downward synchronously. During the downward movement of the piston plate 12, the electrolyte in the injection chamber 11 can enter the inside of the battery casing 91 through the hose 73, the first injection rod 71 and the second injection rod 72. In this process, the insertion action is buffered and decelerated, and the electrolyte injection step is completed simultaneously, improving the assembly efficiency and coordination.
[0030] This embodiment describes a graphene battery cell housing buffer device. The lifting plate 4 is provided with a first horizontal limiting groove 41 and a second horizontal limiting groove 42 along the horizontal direction. The mounting plate 5 is provided with a receiving cavity 53. The receiving cavity 53 is provided with a first inclined limiting groove 51 and a second inclined limiting groove 52. The inclined direction of the first inclined limiting groove 51 is opposite to the inclined direction of the second inclined limiting groove 52. The top of the first clamping rod 61 is movably disposed in the first horizontal limiting groove 41. The bottom of the first clamping rod 61 is movably disposed in the first inclined limiting groove 51. The top of the second clamping rod 62 is movably disposed in the second horizontal limiting groove 42. The bottom of the second clamping rod 62 is movably disposed in the second inclined limiting groove 52. The graphene battery cell housing buffer device described in this embodiment includes a first clamping rod 61 with a first clamping groove 81 in the horizontal direction; a first clamping claw 82 slidably disposed in the first clamping groove 81; a first clamping spring 83 disposed between the first clamping claw 82 and the first clamping groove 81; a second clamping rod 62 with a second clamping groove 84 in the horizontal direction; a second clamping claw 85 slidably disposed in the second clamping groove 84; and a second clamping spring 86 disposed between the second clamping claw 85 and the second clamping groove 84. This embodiment describes a graphene battery cell housing buffer device. One side of the mounting plate 5 has a first liquid injection groove 74 communicating with a receiving cavity 53 along a horizontal direction; a first liquid injection rod 71 is slidably disposed between the first liquid injection groove 74 and the receiving cavity 53; a first liquid injection spring 75 is disposed between the first liquid injection groove 74 and the first liquid injection rod 71; the other side of the mounting plate 5 has a second liquid injection groove 76 communicating with the receiving cavity 53 along a horizontal direction; a second liquid injection rod 72 is slidably disposed between the second liquid injection groove 76 and the receiving cavity 53; a second liquid injection spring 77 is disposed between the second liquid injection groove 76 and the second liquid injection rod 72; the bottom of the first clamping rod 61 is used to abut against the first liquid injection rod 71; the bottom of the second clamping rod 62 is used to abut against the second liquid injection rod 72. In this embodiment, a graphene battery cell insertion buffer device is provided. The top of the support 3 is equipped with a cylinder 31; the output end of the cylinder 31 is equipped with a compression plate 32; the compression plate 32 is located at the bottom of the lifting plate 4; a second tension spring 33 is provided between the compression plate 32 and the lifting plate 4. In this embodiment, the support 3 is provided with a guide protrusion 34 along the lifting direction; both the lifting plate 4 and the mounting plate 5 are provided with dovetail grooves 43 that cooperate with the guide protrusion 34. In this embodiment, the positioning seat 2 is provided with a support rod 22 for abutting against the bottom surface of the mounting plate 5; the support rod 22 is located at the bottom of the guide protrusion 34; a return spring 13 is provided between the bottom of the piston plate 12 and the injection chamber 11.
[0031] Specifically, in the graphene battery cell housing buffer device described in this embodiment, when it is first used, under the action of the first tension spring 64, the top of the first clamping rod 61 is located inside the first horizontal limiting groove 41, the bottom of the first clamping rod 61 is located at the top of the first inclined limiting groove 51, the top of the second clamping rod 62 is located inside the second horizontal limiting groove 42, and the bottom of the second clamping rod is located at the top of the second inclined limiting groove 52, so that the first clamping rod 61 and the second clamping rod 62 are close to each other. At this time, the distance between the first clamping claw 82 and the second clamping claw 85 is relatively close, and under the action of the first liquid injection spring 75 and the second liquid injection spring 77, the first liquid injection rod 71 and the second liquid injection rod 72 are close to each other.
[0032] First, place the battery casing 91 in the positioning groove 21 and on top of the piston plate 12. At the same time, open the first clamp 82 and the second clamp 85 to clamp the battery cell 92 between the first clamp 82 and the second clamp 85. Then, start the cylinder 31. The compression plate 32 drives the lifting plate 4 to move downward through the second tension spring 33. Under the action of the first tension spring 64, the mounting plate 5 moves downward with the lifting plate 4. The first injection rod 71 and the second injection rod 72 move downward with it. When the first injection rod 71 and the second injection rod 72 abut against the top surface of the battery casing 91, the liquid outlet of the first injection rod 71 and the liquid outlet of the second injection rod 72 both face the inside of the battery casing 91.
[0033] Then, the compression plate 32 continues to drive the lifting plate 4 to descend, thereby causing the lifting plate 4, mounting plate 5, battery cell 92, battery casing 91, and piston plate 12 to move downwards synchronously. During the downward movement of the piston plate 12, the electrolyte in the injection chamber 11 can enter the battery casing 91 through the hose 73, the first injection rod 71, and the second injection rod 72. Until the bottom surface of the mounting plate 5 abuts against the support rod 22, the mounting plate 5 can no longer move downwards. At this time, the compression plate 32 continues to drive the lifting plate 4 to descend, causing the lifting plate 4 to move downwards relative to the mounting plate 5. Under the action of the first horizontal limiting groove 41, the second horizontal limiting groove 42, the first inclined limiting groove 51, and the second inclined limiting groove 52, the first clamping rod 61 and the second clamping rod 62 overcome the action of the first tension spring 64 and move away from each other. The first clamping rod 82 and the second clamping rod 85 release the battery cell 92. When the first clamping rod 61 moves to the bottom of the first inclined limiting groove 51 and the second clamping rod 62 moves to the bottom of the second inclined limiting groove 52, the first clamping rod 61 pushes the first injection rod 71 to move, and the second clamping rod 62 pushes the second injection rod 72 to move, so that the first injection rod 71 and the second injection rod 72 move away from each other. At this time, the first injection rod 71 and the second injection rod 72 no longer abut against the top surface of the battery casing 91. Under the action of the return spring 13, the battery casing 91 moves upward. At this time, the compression plate 32 continues to drive the compression plate 32 to move downward. The compression plate 32 overcomes the action of the second tension spring 33 and directly drives the battery cell 92 to move downward, so that the battery cell 92 and the battery casing 91 are assembled.
[0034] This embodiment describes a graphene battery cell housing buffer device. The first clamping rod 61 is provided with a guide rod 63; the mounting plate 5 has a guide groove 54 along the lifting direction; the guide rod 63 is movably disposed in the guide groove 54; the second clamping rod 62 is slidably disposed on the guide rod 63; a first tension spring 64 is provided between the first clamping rod 61 and the second clamping rod 62; the first tension spring 64 is sleeved on the outside of the guide rod 63. This arrangement allows the first clamping rod 61 and the second clamping rod 62 to move stably.
[0035] The graphene battery cell insertion buffer device described in this embodiment includes a first one-way valve 14 between the electrolyte injection chamber 11 and the flexible tube 73. This design prevents the electrolyte in the flexible tube 73 from flowing back into the electrolyte injection chamber 11.
[0036] This embodiment describes a graphene battery cell casing buffer device. The frame 1 includes a storage chamber 15 communicating with the injection chamber 11. A second one-way valve 16 is provided between the injection chamber 11 and the storage chamber 15. The frame 1 also includes a replenishment port 17 communicating with the storage chamber 15. With these features, after injection is complete, the piston plate 12 resets, allowing the electrolyte in the storage chamber 15 to flow into the injection chamber 11.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
