When the first cylinder drives the suction nozzle to move downward, the suction nozzle can retract into the support block and release the packaging card so that the packaging card falls onto the support block. After the packaging card falls onto the support block, the second cylinder can drive the sliding seat to move forward. At this time, the push plate can push the packaging card on the support block to move forward so that the front end of the packaging card is inserted into the gap between the heat shrink film and the battery pack. After the front end of the packaging card is inserted into the gap between the heat shrink film and the battery pack, the second cylinder can drive the sliding seat to move backward, so that the sliding seat drives the push plate to move backward and reset.

[0022] The supporting structure includes two screw groups 58 which are symmetrically arranged front to back. The two screw groups 58 are respectively threadedly connected to the front and rear side walls of the lower end of the packaging card storage rack 52. The inner ends of the two screw groups 58 extend into the packaging card storage rack 52 and are respectively used to support the front and rear ends of the packaging card located in the packaging card storage rack 52.

When the front end of the packaging card is inserted into the gap between the heat shrink film and the battery pack 4, the third cylinder 502 is used to drive the movable block 501 to move downward and reset so that the rear end of the packaging card is separated from the upper end surface of the movable block 501 and then suspended in the air. By adopting this structure, the packaging card feeding mechanism can In the process of inserting the packaging card from back to front into the gap between the heat shrink film and the battery pack, the upper end surface of the movable block can guide the packaging card so that the front end of the packaging card is inserted into the gap between the heat shrink film and the battery pack. When the front end of the packaging card is inserted into the gap between the heat shrink film and the battery pack, the third cylinder can drive the movable block to move downward and reset so that the rear end of the packaging card is separated from the upper end surface of the movable block and is suspended in the air. At this time, after the blocking mechanism releases the obstruction to the battery pack, during the process that the first conveyor belt assembly continues to drive the battery pack forward, since the rear end of the packaging card inserted between the heat shrink film and the battery pack does not contact the first conveyor belt assembly, the packaging card inserted between the heat shrink film and the battery pack can be prevented from being skewed during the process that the first conveyor belt assembly transports the battery pack with the packaging card inserted.

[0025] The material blocking mechanism includes a material blocking frame 61, a fourth cylinder 62, a material blocking block 63 and a fifth cylinder 64.

After the battery pack is put into the oven, the material blocking mechanism can release the blocking of the battery pack. At this time, the battery pack covered with heat shrink film and inserted with packaging card can be conveyed to the hot air gun. The hot air gun can preheat the heat shrink film pre-covered on the outside of the battery pack so that the heat shrink film shrinks and then tightly wraps the battery pack and the packaging card. Finally, the first conveyor belt assembly can transfer the battery pack heated by the hot air gun to the second conveyor belt assembly. When the second conveyor belt assembly conveys the battery pack to the location of the oven, the oven can further heat the heat shrink film covered on the outside of the battery pack so that the heat shrink film shrinks and then further tightly wraps the battery pack and the packaging card.
