Among them, when packing the lithium battery pack PACK, the raw materials of the components of each structure of the lithium battery pack are assembled and installed.

[0003] The traditional lithium battery pack is composed of a battery pack, an outer shell, an upper pressure plate, a tray, a metal bracket, an end plate and bolts. After the outer shell is installed on the outside of the battery pack, the upper pressure plate is finally connected to the outer shell to complete the packaging of the battery pack and obtain a lithium battery pack. The existing upper pressure plate installation is usually performed by a worker positioning the upper pressure plate on the mounting surface of the outer shell, and then using screw fasteners to fix and lock the upper pressure plate to the outer shell. However, the upper pressure plates are usually stacked and stored before being put into installation and use, so that the raised structures on the surface of the upper pressure plates are prone to mutual friction and scraping contact during the stacking process, resulting in scratches on the surface of the upper pressure plate, which affects the continued installation and use of the upper pressure plate and causes the loss of the raw materials of the upper pressure plate.

[0030] In the specific implementation process of the present invention, first, a group of lithium battery packs 2 and a structure installed with a tray tooling 5 are placed between the flipping components on the feeding channel 4 to perform the flipping operation.

Then, the controller controls the flip cylinder 10 to flip 90° and make the fixed plate 17 and the negative pressure suction cup 18 in a vertical state and parallel to the upper pressing plate 3. Then, the controller controls the pneumatic clamp to move to the side of the upper pressing plate 3 until the negative pressure suction cup 18 fits with the upper pressing plate 3. Then, the controller controls the vacuum pump to press the vacuum pipe 19 is used to evacuate air so that the negative pressure suction cup 18 is tightly adsorbed on the upper pressure plate 3, and then the controller controls the sliding adjustment of the gantry linear module and drives the pneumatic clamp and the upper pressure plate 3 to move to the lithium battery pack 2 under the gantry linear module, and then controls the flip cylinder 10 to flip 90° in the opposite direction again, so that the fixed plate 17, the negative pressure suction cup 18 and the upper pressure plate 3 are in a horizontal state, and the controller controls the gantry linear module to drive the upper pressure plate 3 to move downward and place it on the top of the lithium battery pack, and the controller cancels the vacuum pump control to eliminate the suction between the negative pressure suction cup 18 and the upper pressure plate 3, and then the fixed plate 17 and the negative pressure suction cup 18 are slidably adjusted away from the upper pressure plate 3 through the gantry linear module to complete the loading operation.

[0032] Finally, the tray tooling 5 and the lithium battery pack 2 are moved along the slide groove 32 of the feeding channel 4 to the bottom of the screw locking mechanism, and the screw installation and locking operation of the upper pressure plate 3 and the lithium battery pack 2 are carried out. First, the first driving member 42 and the second driving member 43 of the controller drive the sliding adjustment of the first slide 34 and the second slide 35, thereby driving the locking driver 37 and the universal connecting tube 38 to move toward the lithium battery pack 2 below it until the universal connecting tube 38 contacts the upper pressure plate 3, so that the screw in the universal connecting tube 38 falls on the upper pressure plate 3, and then the controller controls the locking driver 37 to drive the universal connecting tube 38 to rotate, driving the screw to cooperate with the upper pressure plate 3 and the top thread of the lithium battery pack 2 to be installed, and the screw is locked between the upper pressure plate 3 and the lithium battery pack 2, thereby completing the screw installation and locking operation.

[0033] During this process, each time the pallet tool 5 slides forward to a station, a new set of pallet tool 5 and the lithium battery pack 2 to be processed are placed between the turning components on the workbench 1.

[0034] Compared with the prior art, the utility model is provided with a material rack. By arranging a material rack 6 and clamping rails 7 on both sides thereof, the two ends and the bottom of the upper pressing plate 3 are respectively accommodated and fixed, thereby realizing the vertical placement and storage of the upper pressing plate 3. By arranging the side limit grooves 8 and the bottom limit grooves 9, it is convenient to limit the upper pressing plate 3, so that the upper pressing plate 3 is placed more stably, and the upper pressing plate 3 is avoided from tipping over and scraping each other. By arranging the gantry linear module and the pneumatic clamp, it is convenient to clamp and transport the upper pressing plate 3, making loading more convenient. By arranging the flipping cylinder 10, the vertically placed upper pressing plate 3 is flipped and adjusted to a horizontal installation state. The installation is convenient, the loss of the material of the upper pressing plate 3 is avoided, the production and processing efficiency of the lithium battery pack 2 is improved, and the problem that the upper pressing plates of the traditional lithium battery pack are stacked and placed before being installed with the lithium battery pack is solved, which is easy to cause scratches between the upper pressing plates and the loss of the raw materials of the upper pressing plates.
