[0020] In this embodiment, the lifting assembly 2 is lowered to the lowest position, and then the power battery pack to be disassembled is sent to the lifting assembly 2 by the upper conveying device, and then the lifting assembly 2 lifts the power battery pack to be disassembled to be flush with the top of the conveying assembly 1, and then the pushing assembly 3 pushes the power battery pack to be disassembled onto the conveying assembly 1; The conveying component 1 transports the power battery pack to be disassembled through the scanning component 4, the disassembly component 5 and the separation component 6 in sequence. The scanning component 4 is used to scan the screw positions of the power battery pack to be disassembled, specifically to obtain a photo of the surface of the battery pack, and analyze the above photo through an external computer through a built-in algorithm to obtain the position of the bolts. The disassembly component 5 is controlled by the external computer to remove the bolts on the battery pack. After the bolts are removed, the battery pack is separated from its upper cover through the separation component 6.

[0021] Furthermore, the lifting assembly 2 includes an unpowered conveying roller 21 and a plurality of electric guide rails 22. The unpowered conveying roller 21 is horizontally arranged at one end of the conveying assembly 1 for loading materials, and the plurality of electric guide rails 22 are vertically arranged around the unpowered conveying roller 21, and the movable seat of each electric guide rail 22 is fixedly connected to the side wall of the unpowered conveying roller 21.

[0022] In this embodiment, the unpowered conveying roller 21 is driven to rise and fall by four rectangular electric guide rails 22. The electric guide rail 22 drives the unpowered conveying roller 21 to descend to the lowest point, and a baffle is provided at the end away from the upper position to prevent the battery pack from slipping out of the unpowered conveying roller 21.

[0023] Furthermore, the pushing assembly 3 includes a first bracket 31, a pushing plate 32 and at least one cylinder 33.

The pushing plate 32 is arranged on the piston rod of the cylinder 33, and its bottom end is flush with the top end of the conveying assembly 1.

[0024] In this embodiment, the first bracket 31 is used to support the cylinder 33. When the lifting assembly 2 drives the battery pack to rise to be flush with the conveying assembly 1, the cylinder 33 drives the push plate 32 to push the battery pack onto the conveying assembly 1. The battery pack is then transported by the conveying assembly 1 and disassembled during the transportation process.

[0026] In this embodiment, multiple cameras 42 are horizontally arranged at the top of the warehouse body 41, and their arrangement direction is perpendicular to the transportation direction of the conveying component 1. When the battery pack passes under the camera 42, multiple photos of the surface of the battery pack are taken by the camera 42. The camera 42 is connected to an external computer electrical signal, and the taken photos are input into the computer for processing. The computer has a built-in algorithm, which processes the photos and marks the position of the bolts on the battery pack and the size of the corresponding bolts.

[0027] Furthermore, the disassembly component 5 includes a second bracket 51 and two robotic arms 52. The second bracket 51 is arranged at the bottom of the transmission component 1 and has a certain distance from the scanning component 4.

[0031] Furthermore, it also includes two translation components 7, which are respectively arranged on both sides of the transmission component 1, and the two ends of the separation component 6 are respectively connected to the two translation components 7.

[0032] In this embodiment, the translation component 7 can drive the separation component 6 to move horizontally.

[0033] Furthermore, the translation assembly 7 includes a slideway 71, a screw rod 72, a slider 73 and a drive motor 74, which is slidably arranged at the bottom of one side of the transmission assembly 1. The screw rod 72 is arranged in the slide groove of the slideway 71, and its two ends are rotatably connected to the inner wall of the slide groove through bearings. The slider 73 is arranged in the slide groove of the slideway 71 and is threadedly connected to the screw rod 72. The drive motor 74 is arranged on the outer wall of the slideway 71, and its output shaft is transmission-connected to the screw rod 72.

[0034] In this embodiment, the driving motor 74 drives the screw rod 72 to rotate, and the rotation of the screw rod 72 drives the slider 73 to translate in the slide groove of the slideway 71, so that the separation component 6 on the slider 73 moves; The driving motors 74 in the two translation assemblies 7 are controlled to rotate by a controller.

[0035] Furthermore, the separation component 6 includes a frame 61, a support plate 62 and at least one electric cylinder 63.

[0036] In this embodiment, when the battery pack with the bolts removed moves to the bottom of the frame 61, the conveying component 1 stops transporting, and the electric cylinder 63 drives the support plate 62 to move downward to the top of the battery pack, and then the upper cover of the battery pack is clamped by two clamping units 64 using existing technology on the support plate 62. After clamping, the electric cylinder 63 drives the support plate 62 to move upward, and then the translation component 7 drives the frame 61 to move a distance toward the unloading end of the conveying component 1, and places the upper cover on the conveying component 1, and then the translation component 7 and the separation component 6 are reset, and finally the conveying component 1 drives the battery pack without the upper cover and the upper cover to move to the lower transfer mechanism, and the battery pack without the upper cover and the upper cover are respectively sent to different areas for subsequent processing through the transfer mechanism.

[0037] Furthermore, the conveying assembly 1 is a roller conveying mechanism.

[0038] In this embodiment, the roller conveying mechanism adopts the equipment of the prior art.

[0039] The present invention is a disassembly device for a power battery pack upper cover, which delivers the power battery pack to be disassembled to a conveying assembly at a certain height through a lifting assembly and a pushing assembly, thereby eliminating the need for manual handling of the battery pack, and the conveying assembly at a certain height facilitates workers to inspect the assembly line during the disassembly process; The bolt positions of the power battery pack to be disassembled are scanned and marked by the scanning component, and after the bolts are removed by the disassembly component, the power battery pack to be disassembled and its upper cover are separated by the separation component.
