Description

Technical Field

[0001] This utility model relates to the technical field of battery pack processing and production, and in particular to a device for removing modules from inside a battery pack. Background Technology

[0002] With the rapid development of the new energy industry, the use of battery packs is increasing. Even after their lifespan is exhausted, battery packs still have significant recycling value, thus requiring a method and equipment for quickly disassembling them and removing the internal modules. Currently, to ensure sealing and safety, battery packs on the market have very robust casing structures, with internal modules bonded to the casing using structural adhesive, making disassembly and module removal extremely difficult. Conventional module removal requires first damaging the battery pack casing structure, then using chemical methods to remove the structural adhesive, and finally prying out the module, resulting in considerable damage to both the module and the battery pack casing.

[0003] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a device for removing modules from a battery pack, making it more industrially valuable. Utility Model Content

Lifting frames distributed along the left-right direction are installed on the inner side of the lifting and positioning frames. Lifting cylinders installed on the lifting and positioning frames below the lifting frames drive lifting wedges to move in the left-right direction.

[0010] As a further improvement of this utility model, the frame base mechanism includes two support frames installed side by side on the ground in the front-to-back direction. The bottom of the support frames is equipped with foot plates. At least one first linear guide rail distributed in the left-to-right direction is installed on the support frames.

[0013] As a further improvement of this utility model, both the stripping roller and the winding drive module are mounted on the lifting seat, and the lifting electric cylinder mounted on the top of the stripping frame drives the lifting seat to move vertically along the second linear guide rail.

[0014] As a further improvement of this utility model, the extrusion mechanism includes an extrusion frame mounted on a frame base mechanism, an extrusion base mounted on the extrusion frame, a transfer drive module mounted on one side of the extrusion base that is adapted to a second rack mounted on the extrusion frame and drives the extrusion base to move along the front-back direction on a third linear guide rail, an extrusion electric cylinder mounted on the extrusion base that drives the extrusion tooling plate below to move along the vertical direction on a guide rod; and a synchronous drive mechanism mounted on the right side of the extrusion frame that drives the extrusion frame to move along the left-right direction on the frame base mechanism.

[0035] like Figures 1-5 As shown, a device for removing modules from a battery pack includes a frame base mechanism 2 mounted on the ground. A trolley lifting and positioning mechanism 1 is installed on the ground inside the frame base mechanism 2 for lifting the battery pack from the incoming trolley.

[0041] The purpose of this utility model is to: position the battery pack receiving trolley; wind and peel off the battery pack bottom plate to expose the modules; automatically press out multiple modules from the battery pack onto the receiving trolley; have a visual addressing and positioning function; and can press out modules of various sizes through the tooling plate of the extrusion mechanism.

[0042] Brief description of the working process of this utility model:

[0043] During production, a trolley carrying a battery pack is moved into the equipment manually or by an AGV. The trolley guide structure 109 is used for limiting and guiding the trolley's movement. After the arrival detection sensor 103 detects that the trolley has arrived, the trolley clamping cylinder 110 actuates to clamp the trolley and prevent it from moving. Then, the lifting cylinder 106 extends, and the trolley is lifted and positioned by the lifting and positioning mechanism 1. The operator lifts one corner of the bottom plate of the battery pack and inserts it into the groove of the peeling roller 33 for fixation. The equipment is started, and the motor of the winding drive module 32 rotates, driving the peeling roller 33 to perform winding and peeling. During the peeling process, as the bottom plate winds on the peeling roller 33, the outer diameter of the peeling roller 33 increases. The lifting cylinder 36 actuates to lift the peeling roller to adapt to the change in the outer diameter of the peeling roller 33, ensuring that the product is not squeezed. During the winding of the bottom plate by the peeling roller 33, the peeling mechanism 3 advances on the frame base mechanism 2 due to the winding tension until the bottom plate is completely peeled off. After the stripping is completed, the motor of the synchronous drive mechanism 49 drives the gear-driven pressing mechanism 4 to move on the frame base mechanism 2, and pushes the stripping mechanism 3 to the loading port of the equipment. At this time, the stripping mechanism 3 is located at the head of the equipment, exposing the battery pack module pressing area. The synchronous drive mechanism 49 moves, moves the pressing mechanism 4, and moves the vision system 48 to the Mark points at the three corners of the battery pack to take pictures. The vision software calculates the positional deviation of the battery pack in the equipment and feeds it back to the PLC. The PLC corrects the module pressing position according to the position. The pressing mechanism 4 moves so that the pressing fixture plate 47 is directly above the module. The pressing cylinder 45 descends, and the speed slows down when it approaches the module. The pressing fixture plate 47 slowly contacts the module, and under the action of the pressing cylinder 45, the module is pressed out and separated from the battery pack box. After the module is separated, it falls directly into the receiving trolley. The pressing is completed, and the pressing mechanism 4 returns to its original position. The lifting cylinder 106 retracts, the lifting frame 104 descends, the trolley positioning pin 105 disengages from the trolley, releasing the trolley, which is then manually or by AGV pulled away. The operator uses hooks to secure the end of the base plate wound on the stripping roller 33 to the unwinding column 26. The equipment is then started, the pressing mechanism 4 drives the stripping mechanism 3 to move, and simultaneously the winding drive module 32 motor drives the stripping roller 33 to reverse, flattening the base plate on the stripping roller 33. After flattening, the operator manually removes the base plate, completing the module removal of the battery pack.

[0044] For modules of different sizes, the extrusion tooling plate 47 is replaced for matching. The tooling plate to be changed is placed on the changing table 29, and the extrusion mechanism 4 can be automatically moved to the changing table 29 for easy extrusion of the tooling plate 47.

[0045] The mechanism enables the peeling off of the battery pack base plate, exposing the module. After exposure, a pressing mechanism, combined with visual positioning, automatically presses out the module. The automatic peeling of the battery pack water-cooling plate is achieved through a trolley positioning mechanism, peeling mechanism, and pressing mechanism, and it possesses flexible functionality for different product applications. In actual production, it is efficient, safe, and eliminates the need for cumbersome steps to remove structural adhesive, minimizing battery damage and significantly improving recycling yield.
