Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and in particular to a structure for loading and unloading battery packs into and out of a prefabricated energy storage compartment. Background Technology

[0002] During the production of prefabricated battery storage compartments or storage cabinets, battery packs need to be packed into containers. Forklifts are often used for transportation and lifting into the containers. When packing, the two sides of the battery pack need to be aligned with the slots in the container before sliding it in. Due to uneven ground, the battery pack often tilts to one side. Moreover, because the battery packs are quite heavy, it is not convenient to push them into the container manually. Therefore, some handling equipment is needed for assembly. During the commissioning process in the factory, battery pack failures are often encountered, requiring repair or replacement. At this time, because there is no space between the battery packs to accommodate the insertion arm, it is impossible to remove the battery pack. Utility Model Content

[0050] The working principle of this utility model is as follows: The operator sets the target storage layer height through the power control box 1, the lifting motor 38 starts, and the drive gear 39 drives the driven gear 37 to rotate; the lifting screw 35 rotates with the driven gear, and drives the lifting seat 31 to rise / fall vertically along the lifting guide rail 21 through the screw slider 36.

[0052] The sensor detects that the battery pack has reached the edge of the rolling tray. The push screw 62 rotates under the support of the push fixing plate 61, driving the push slide 63 to move along the contact groove 65. The contact block 64 contacts the side of the battery pack, pushing it from the rolling tray 4 into the storage guide rail 101 by thrust.

[0053] The target battery pack is selected via the power control box 1. The pushing mechanism 6 rotates the pushing screw 62 in the opposite direction, pulling the battery pack out of the storage guide rail 101. The traction mechanism 5 simultaneously releases the traction rope 53, assisting the battery pack to return to the center of the rolling tray 4. The vertical lifting mechanism 3 adjusts the height of the rolling tray to the unloading position, and the traveling chassis 11 moves the mechanism to the designated unloading area via the traveling wheels 12 and omnidirectional wheels 14.
