[0022] Example 1:

[0023] like Figure 1 As shown, this embodiment provides a CTP battery pack disassembly puller. The CTP battery pack includes a housing with a pre-separated top cover and battery cells disposed inside the housing and bonded to the housing with adhesive. It includes a base 1 and a platform 2 mounted on the base 1. A lifting assembly 4 is embedded on the upper surface of the platform 2. The lifting assembly 4 includes a telescopic rod that can extend and retract in the vertical direction. Two hook assemblies are installed on the platform 2. The hook assemblies include hook portions 31 that can move up and down. When disassembling the CTP battery pack, the CTP battery pack with the pre-separated top cover is placed on the platform 2. The hook portions 31 of the two hook assemblies are hooked onto the tops of two opposite side plates of the housing. The telescopic rod of the lifting assembly 4 can extend to abut against the bottom of the housing and squeeze the bottom of the housing, so as to separate the battery cells bonded to the housing with adhesive from the housing.

[0024] In this embodiment, the bottom of the base 1 is a circular plate, and mounting holes are evenly arranged around its center line. The circular plate can be connected to the corresponding mounting surface by bolts and nuts. The circular plate has a columnar body, and a platform 2 is mounted on the columnar body.

[0025] like Figure 1As shown, the CTP battery pack includes a shell with a pre-separated top cover, and a battery cell arranged in the shell; the CTP battery pack disassembly puller device is mainly composed of a base 1 and a placement table 2 mounted on the base 1; the upper surface of the placement table 2 is specially embedded with a jacking assembly 4, and the core component of the jacking assembly 4 is a telescopic rod capable of flexible expansion in the vertical direction, which has the action of exerting force during the entire disassembly process; at the same time, two hook assemblies are also mounted on the placement table 2, and each hook assembly includes a hook part 31 capable of moving up and down. When entering the CTP battery pack disassembly process, first, the battery pack with the pre-separated shell top cover is placed on the placement table 2; then, the two hook assemblies are operated so that the hook parts 31 are hooked at the top positions of the two opposite side plates of the shell; at this time, the jacking assembly 4 is started, and the telescopic rod of the jacking assembly 4 starts to elongate in the vertical direction, and as the telescopic rod elongates, its top gradually abuts against the bottom of the shell and continuously exerts a pressing force, under the action of this pressing force, the battery cell originally closely connected with the shell by adhesive begins to gradually separate from the shell. The CTP battery pack disassembly puller device realizes the separation of the battery cell from the shell in a relatively simple and efficient way through the action of mechanical force, greatly improves the disassembly efficiency of the CTP battery pack, and at the same time, to a certain extent, guarantees the integrity of the battery cell and the shell during the disassembly process, and reduces the damage risk that may be caused by improper disassembly.

[0026] As shown in the figure, Figure 1 The hook assembly includes a hook piece 3, the top of the hook piece 3 is a hook part 31, and the hook part 31 is located above the placement table 2; the middle part of the hook piece 3 is a sliding part capable of sliding in the vertical direction, and the sliding part is slidably limited on the placement table 2; the bottom of the hook piece 3 is a threaded part 32 with external threads, and the threaded part 32 is located below the placement table 2, and the threaded part 32 is threadedly connected with a fastener 33; when disassembling the CTP battery pack, the fastener 33 abuts against the lower surface of the placement table 2.

[0027] In this embodiment, the fastener 33 is a nut; the hook piece 3 is designed in multiple types, and the hook parts of different types of hook pieces 3 are different in size and can hook battery packs of different sizes.

[0028] When disassembling the CTP battery pack, rotate the fastener 33 to gradually move it upward and abut against the lower surface of the workbench 2. At this time, the fastener 33 can provide a certain pre-tightening force to ensure that the hook component 3 remains stable during the entire disassembly process and does not loosen or shift due to external forces. The design of this hook assembly has significant advantages in CTP battery pack disassembly. On the one hand, it can effectively reduce the work intensity of the operator, and through the suspension and fixation method, the battery pack is more easily operated and handled during disassembly. On the other hand, in terms of structural design and connection method, the safety and stability of the disassembly process can be ensured, and the safety risk and equipment damage risk caused by component shaking or falling are reduced. At the same time, the adjustability and universality of the hook assembly make it applicable to disassembly work of CTP battery packs of different specifications and models, improving work efficiency and resource utilization.

[0029] The part of the hook component 3 that protrudes above the workbench 2 is provided with a limiting piece 34.

[0030] In this embodiment, when the fastener 33 is loosened, the limiting piece 34 falls on the upper surface of the workbench 2, preventing the hook component 3 from detaching from the workbench 2.

[0031] As shown in Figure 2 , two long holes 21 are provided on the workbench 2, and the sliding parts of the two hook components 3 are respectively arranged in the corresponding long holes 21.

[0032] The jacking assembly 4 is embedded in the center position of the upper surface of the workbench 2, and the two long holes 21 are symmetrically arranged with the center line of the telescopic rod of the jacking assembly 4 as the axis of symmetry.

[0033] The jacking assembly 4 is any one of a hydraulic cylinder, a jack, a pneumatic jacking column, and an electric push rod.

[0034] In this embodiment, a jack is selected.

[0035] The workbench 2 includes a connecting part 22 connected to the base 1, and two mounting parts 23 located on both sides of the connecting part 22, and two hook assemblies are respectively mounted on the corresponding mounting parts 23.

[0036] In this embodiment, the two long holes 21 are respectively provided on the two mounting parts 23.

[0037] The mounting part 23 is in a long strip shape, the upper surface of the connecting part 22 is provided with an embedding groove 24, and the jacking assembly 4 is embedded in the embedding groove 24.

[0038] In this embodiment, when the jacking assembly 4 is fully retracted, the upper end surface of the telescopic rod of the jacking assembly 4 and the upper surface of the workbench 2 are in the same plane.

[0039] Working principle:

[0040] Before the CTP battery pack 5 is disassembled, the top cover of the shell needs to be separated in advance.

[0041] As shown in Figure 3 When disassembling, the following steps are included:

[0042] Step one, place the battery pack with the top cover of the shell separated in advance on the workbench 2;

[0043] Step two, move the two fasteners 33 downward relative to the hook parts 31, and then move the hook parts 3 upward, so that the two hook parts 31 are hooked on the top ends of the two side plates of the shell respectively;

[0044] Step three, rotate the fasteners 33 so that the fasteners 33 abut against the lower surface of the workbench 2;

[0045] Step four, start the jacking assembly 4, so that the telescopic rod of the jacking assembly 4 abuts against the bottom of the shell and extrudes the bottom of the shell by elongation, so as to separate the battery cell bonded with the shell from the shell.

[0046] In this process, the bottom of the shell is deformed, so that the glue layer at the bottom of the battery cell is peeled off, and the whole battery cell is peeled off. The CTP battery pack disassembling puller device of the utility model can avoid directly extruding the battery cell, so that the battery pack can be disassembled at room temperature, and therefore it is safer and more efficient; the battery cell can be prevented from being deformed, and can be reused.

[0047] The above utility model is only several specific embodiments of the utility model, but the utility model embodiments are not limited to this, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the utility model.
