[0036] like Figure 1 、 Figure 4 、 Figure 6 and Figure 7 As shown, the output end of the motor 32 is connected to a connector 321, and an annular plate 3211 is provided below the connector 321. The annular plate 3211 is slidably connected to the annular groove 111, which can limit the rotation direction of the turntable 31. The connector 321 passes through the interior of the through hole 112, and the end of the connector 321 away from the motor 32 is connected to the turntable 31. Two first sliding grooves 311 are symmetrically provided on the upper interior of the turntable 31, and two protrusions 351 are symmetrically provided below the first support plate 35.

[0037] like Figure 1 、 Figure 4 、 Figure 5 and Figure 8 As shown, multiple first springs 34 are connected between the first support plate 35 and the first mounting plate 33, which facilitates the lithium battery to squeeze the first support plate 35 from the side of the first support plate 35 away from the first spring 34, and utilizes the rebound characteristics of the first spring 34 to clamp the lithium battery. A first pin rod 331 is provided in the upper middle part of the first mounting plate 33, and a mounting block 353 is provided in the upper middle part of the side of the first support plate 35 close to the first mounting plate 33. A connecting hole 3531 is opened in the middle of the mounting block 353 to facilitate the placement of the limiting structure 36. A limiting structure 36 is provided above the mounting block 353.

[0038] like Figure 1 、 Figure 4 and Figure 5 As shown, the limiting structure 36 includes a second pin rod 361 and a connecting plate 362.

A plurality of first limiting holes 3621 are equally spaced inside the connecting plate 362. The first pin rod 331 passes through the interior of the first limiting hole 3621. After the lithium battery is assembled, the first limiting hole 3621 connected by the first pin rod 331 can be replaced to further compress the first spring 34 to release the clamping of the lithium battery by the first resist plate 35, thereby facilitating the removal of the lithium battery from the turntable 31.

[0039] like Figure 1 、 Figure 4 and Figure 8As shown, both ends of the first support plate 35 are provided with limiting rods 352, and both ends of the second support plate 39 are provided with second limiting holes 391.

A partition 451 is provided in the middle of the storage box 45 to separate the positive and negative poles of the battery cell, which is convenient for workers to take. Second slide grooves 421 are provided at both ends of the support ring 42, and a card slot 422 is provided at one end of the second slide groove 421. A second protrusion 452351 and a third protrusion 453351 are respectively provided at both ends of the lower side of the storage box 45.

The card block 4531 is engaged with the card slot 422 to facilitate limiting the position of the storage box 45.

[0041] like Figure 1 As shown, the distance between the highest point of the second bracket 41 and the ground is smaller than the height of the support leg 13, and the number of the support ring 42 is one more than the storage box 45. When the storage mechanism is idle, the top storage box 45 can be removed and placed on the empty support ring 42 to lower the overall height of the storage mechanism so that the storage mechanism can be placed under the supporting plate 11, thereby saving the space occupied by the entire assembly device. The interior of the second slide groove 421 is provided with a dustproof strip 43, which can keep the second slide grooves 421 at both ends of the empty support ring tidy when the storage mechanism is idle or in use, thereby reducing the cleaning workload.

According to the ratio of the cells, protective plates and other accessories, a number of protective plates and other accessories that match the cells are placed in the remaining storage boxes 45, and then the transfer mechanism 4 with the lithium battery parts is transferred to one end of the carrier plate 11, the position of the transfer mechanism 4 is adjusted so that it is aligned with the first limit plate 12, and the brake of the universal brake wheel 44 is stepped on to fix it.

[0043] 35. The second battery pack is assembled on the turntable 31 and the second battery pack is assembled on the turntable 31. The battery pack is assembled on the turntable 31 and the second battery pack is assembled on the turntable 31. During the assembly process, the worker can hold the first handle 251 to adjust the pressure plate 25 and the first telescopic rod 24 to above the lithium battery, and then use the controller 5 to control the first telescopic rod 24 to extend, so that the pressure plate 25 squeezes the lithium battery cell and the accessories at both ends downward, so that the cell and the accessories at both ends are firmly connected. Then the first telescopic rod 24 contracts to release the squeezing of the lithium battery cell, and the first handle 251 is held again to move the pressure plate 25 and the first telescopic rod 24 away from above the lithium battery, and then subsequent assembly can be carried out. During the assembly process, the worker can use the controller 5 to start the motor 32, so that the motor 32 drives the turntable 31 and the lithium battery to rotate through the connector 321, so that the annular plate 3211 rotates in the annular groove 111, thereby adjusting the surface of the lithium battery facing the worker, making it convenient for the worker to assemble.

[0044] After the assembly is completed, the second pin rods 361 in the two limiting structures 36 are passed back into the connecting holes 3531, the handle 363 is held, and the first support plate 35 is pulled toward the first mounting plate 33. The spring is further squeezed until the first support plate 35 is separated from the lithium battery. The limiting mechanism is pressed downward so that the first pin rod 331 passes through the first limiting hole 3621 directly above it, and the position of the first support plate 35 is fixed. The second handle 271 is held to move the electric clamping jaw 27 and the second telescopic rod 26 to the top of the lithium battery. The controller 5 is used to control the electric clamping jaw 27 to increase the distance between the two clamping jaws, control the extension of the second telescopic rod 26, and push the clamping jaw downward. When the upper end of the lithium battery is located between the two clamps, close the second telescopic rod 26, control the electric clamp 27 again, narrow the distance between the two clamps to clamp the lithium battery, and then use the controller 5 to control the second telescopic rod 26 to contract and pull the lithium battery upward. After the lithium battery is completely pulled out from between the two second abutment plates 39, stop extending the second telescopic rod 26, hold the second handle 271 again to slide the slider 23 on the slide rail 22 to remove the lithium battery, the electric clamp 27 and the second telescopic rod 26 from the turntable 31, and then control the second telescopic rod 26 to extend and the electric clamp 27 to open, and place the lithium battery on the carrier plate 11 or another empty transfer mechanism 4.

[0045] Then, repeat the above steps to assemble the remaining lithium batteries.

[0046] The controller 5, slide rail 22, slider 23, first telescopic rod 24, second telescopic rod 26, electric clamp 27, motor 32, connector 321, first pin 331, first spring 34, second pin 361, second spring 38, universal brake wheel 44 and other components in a lithium battery assembly device disclosed in the present invention are all universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.
