Description

Technical Field

[0001] The utility model relates to the technical field of battery processing, and particularly designs a battery pack disassembly device. Background Art

[0002] For waste battery packs, the outer shell of the battery pack needs to be disassembled by a disassembly mechanism to recover the battery cell module inside. The disassembly mechanism generally includes an output terminal and a force-applying member fixedly connected to the output terminal. There are two output terminals, which can move in opposite directions or towards each other. The force-applying members correspond to the output terminals one by one. The outer shell of the battery pack is made of two shells. When working, the two force-applying members are placed in the joint seam of the outer shell, and the force-applying members can move in opposite directions to push and disassemble the outer shell. However, during the disassembly process, the outer shell will open in an eight-shaped shape, and the outer shell will push the battery cell module inside it toward the disassembly mechanism. In order to ensure the structural strength and reliability of disassembly, the disassembly mechanism is mostly or entirely made of metal material. Therefore, the positive and negative poles of the battery cell module are easy to contact the disassembly mechanism, causing safety hazards such as short circuit, fire and electric shock.

[0003] Therefore, it is necessary to improve the prior art to overcome the above defects in the prior art. Utility Model Content

[0004] The utility model aims to provide a battery pack disassembly device, which can prevent the battery cell modules in the battery pack from contacting the disassembly mechanism during the battery pack disassembly process.

[0005] The purpose of the utility model is achieved through the following technical solutions: a battery pack disassembly device, used to disassemble the outer shell of the battery pack, comprising:

[0006] A carrier, on which the battery pack to be disassembled can be placed;

[0007] A disassembly mechanism, mounted on the carrier and used to disassemble the housing, the disassembly mechanism being arranged opposite to the battery pack;

[0008] An insulating stopper, mounted on the carrier and located between the disassembly mechanism and the battery pack;

[0009] Wherein, during the disassembly process of the shell, the insulating block is suitable for blocking the battery cell module in the shell so that the battery cell module does not contact the disassembly mechanism.

[0010] Furthermore, the insulating block includes a blocking surface facing the battery pack, and a buffer is provided on the blocking surface, and the buffer is suitable for buffering the housing and / or the battery cell module.

[0011] Furthermore, the buffer component is a foam pad adhered to the blocking surface, and the foam pad covers the entire blocking surface.

[0012] Furthermore, the table surface of the carrier is provided with at least one first connecting hole extending through it in the vertical direction, the insulating block is supported on the table surface of the carrier, and the insulating block is provided with a second connecting hole recessed inward from its bottom surface corresponding to the first connecting hole one by one, and a threaded connector is connected between the first connecting hole and the second connecting hole.

[0013] Furthermore, when the shell moves to a to-be-disassembled position opposite to the disassembly mechanism, the shell abuts against the insulating stopper.

[0014] Furthermore, the insulating block comprises:

[0015] A stopper seat, fixedly connected to the carrier;

[0016] A plurality of stopper bodies, one of which can be selectively connected to the stopper seat in a detachable manner, and a stopper surface facing the housing is formed on the stopper body;

[0017] Wherein, in the direction in which the disassembly mechanism and the battery pack are arranged relative to each other, the thicknesses of the plurality of block bodies are different.

[0018] Furthermore, the shell includes a first side surface facing the insulating stopper, the first side surface has a connecting seam, the shell is provided with disassembly parts on both sides of the connecting seam, and the disassembly mechanism can apply a disassembly force to the disassembly parts.

[0019] Furthermore, the disassembly mechanism comprises:

[0020] A driving assembly, comprising two output ends that can move in opposite directions or towards each other along a first horizontal direction;

[0021] There are two force applying members, which are fixedly connected to different output ends respectively;

[0022] Among them, the battery pack and the disassembly mechanism are arranged relative to each other in a second horizontal direction perpendicular to the first horizontal direction. When the battery pack moves to a position to be disassembled relative to the disassembly mechanism, the two force-applying members can move back to back and apply disassembly forces to different disassembly parts respectively.

[0023] Furthermore, the force-applying member is suitable for engaging with the disassembly portion when moving backward, and the housing gradually opens in an eight-shaped shape in response to the backward movement of the force-applying member, and the first side surface can gradually be offset from the insulating stopper in the first horizontal direction.

[0024] Furthermore, the insulating block includes a blocking surface facing the first side surface and parallel to the first side surface. When the battery pack is in the position to be disassembled, the projection of the connecting seam in the second horizontal direction coincides with the center line of the blocking surface parallel to the vertical direction.

[0025] Compared with the prior art, the utility model has the following beneficial effects: the utility model provides an insulating block between the disassembly mechanism and the battery pack, so that when the disassembly mechanism disassembles the outer shell of the battery pack, the insulating block can block the battery cell module to prevent the battery cell module from contacting the disassembly mechanism, and because the insulating block is insulating, the battery cell module will not cause safety hazards such as short circuit, fire, and electric shock during the disassembly process.

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0034] The terms "including" and "having" and any variations thereof in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0035] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0036] See also Figures 1 to 4 As shown, a battery pack disassembly device corresponding to a preferred embodiment of the utility model is used to disassemble the outer shell 110 of the battery pack 100. The battery pack disassembly device includes a carrier 200, a disassembly mechanism 300 and an insulating block 400 installed on the carrier 200. The battery pack 100 to be disassembled can be placed on the carrier 200. The disassembly mechanism 300 is arranged opposite to the battery pack 100 and is used to disassemble the outer shell 110. The insulating block 400 is located between the disassembly mechanism 300 and the battery pack 100. During the disassembly process of the outer shell 110, the insulating block 400 is suitable for blocking the battery cell module (not shown) in the outer shell 110 so that the battery cell module does not contact the disassembly mechanism 300.

[0037] The utility model sets an insulating block 400 between the disassembly mechanism 300 and the battery pack 100. When the disassembly mechanism 300 disassembles the outer shell 110 of the battery pack 100, the insulating block 400 can block the battery cell module to prevent the battery cell module from contacting the disassembly mechanism 300. Moreover, since the insulating block 400 is insulating, the battery cell module will not cause safety hazards such as short circuit, fire, and electric shock during the disassembly process.

[0038] Further, the battery pack 100 can move along the first horizontal direction and the second horizontal direction perpendicular to the first horizontal direction, so that the battery pack 100 is in a position to be disassembled aligned with the disassembly mechanism 300. When the battery pack 100 is in the position to be disassembled, the movement direction of the disassembly mechanism 300, the disassembly direction of the battery pack 100 and the first horizontal direction are parallel, and the battery pack 100 and the disassembly mechanism 300 are arranged opposite to each other in the second horizontal direction.

[0039] Furthermore, at least one first connection hole 210 is provided through the table surface of the carrier 200 in the vertical direction, and the insulating block 400 is carried on the table surface of the carrier 200. The insulating block 400 is provided with a second connection hole 410 which corresponds to the first connection hole 210 in a one-to-one manner from its bottom surface. A threaded connector (not shown) is connected between the first connection hole 210 and the second connection hole 410. The threaded connector can specifically be a bolt, a screw, etc., to achieve the fixation of the carrier 200 and the insulating block 400. The first connection hole 210 and the second connection hole 410 can be adaptively set according to the actual length of the insulating block 400, and the utility model does not limit this. By adopting the above structure, it can be achieved that the insulating block 400 is firmly fixed to the carrier 200, and there is no additional connection structure around the insulating block 400, so as to avoid limiting the movement of the battery pack 100.

[0040] Furthermore, the insulating block 400 can be made of high-strength insulating materials such as plastic and ceramic to ensure that the insulating block 400 reliably blocks the battery pack 100. The insulating block 400 includes a blocking surface 420 facing the battery pack 100. When the shell 110 moves to the position to be disassembled relative to the disassembly mechanism 300, the shell 110 abuts against the blocking surface 420, that is, when the operator places the battery pack 100, the battery pack 100 can be accurately positioned in the second horizontal direction, so that the operator can align the shell 110 with the disassembly mechanism 300 to improve the disassembly efficiency.

[0041] Since there are many types of battery packs 100 with different sizes in the actual disassembly process, it is difficult for the insulating block 400 to adapt to different types of battery packs 100 in the second horizontal direction. As a preferred embodiment, the insulating block 400 includes a block seat (not shown) fixedly connected to the carrier 200 and a block body (not shown) detachably connected to the block seat. The blocking surface 420 is formed on the block body. By setting a plurality of block bodies with different thicknesses in the second horizontal direction, when different types of battery packs 100 need to be disassembled, block bodies of corresponding thicknesses can be assembled to the block seat to facilitate the positioning of different types of battery packs 100 in the second horizontal direction. The block seat and the block body can be connected by snap-on connection, threaded connection, etc., which are not limited by the present invention.

[0042] Preferably, a buffer 430 may be provided on the blocking surface 420. When the housing 110 moves toward the insulating stopper 400 along the second horizontal direction, the buffer 430 can buffer the housing 110 and / or the battery cell module therein to protect the components on the circuit board of the battery cell module.

[0043] In one embodiment, the buffer 430 may adopt a mechanical buffer structure, for example, a spring and a buffer plate connected to the spring are provided on the blocking surface 420, and the battery cell module in the housing 110 is blocked by the buffer plate. However, the mechanical buffer structure is complex in structure, cumbersome in installation, and high in cost. Preferably, in the present embodiment, the buffer 430 is specifically a foam pad pasted on the blocking surface 420, and the foam pad preferably covers the entire blocking surface 420. The foam pad in the form of pasting is simple to assemble and low in cost. Preferably, when a plurality of block bodies are provided, the thickness of the plurality of block bodies may also be the same, so as to facilitate manufacturing, and by pasting foam pads of different thicknesses on the plurality of block bodies, the positioning of different types of battery packs 100 can be satisfied.

[0044] Furthermore, the shell 110 includes a first side surface 111 facing the insulating block 400, and the insulating block 400 includes a blocking surface 420 facing the shell 110. The first side surface 111 and the blocking surface 420 are parallel, so that when the shell 110 is aligned with the disassembly mechanism 300, the first side surface 111 can be in contact with the blocking surface 420, thereby improving the alignment accuracy and reducing the probability of damage caused by collision between the shell 110 and the insulating block 400.

[0045] The first side surface 111 has a connecting seam 112 , which is perpendicular to the first horizontal direction. Disassembly portions 113 are disposed on both sides of the connecting seam 112 . The disassembly mechanism 300 can apply a disassembly force to the disassembly portions 113 along the first horizontal direction to achieve disassembly of the housing 110 .

[0046] By providing the disassembly portion 113, the disassembly mechanism 300 does not need to be inserted into the joint seam 112, and the distance between the two disassembly portions 113 is much larger than the gap of the joint seam 112, so the placement position of the battery pack 100 is less demanding, and there is no need to adjust the position of the battery pack 100 many times, and the placement operation of the workers is more convenient, which not only reduces the work intensity of the workers, but also effectively improves the disassembly efficiency of the battery pack 100. In addition, since the disassembly mechanism 300 will not be inserted into the joint seam 112, the disassembly mechanism 300 will not damage the battery cell module during the placement of the battery pack 100, which reduces safety hazards, and the integrity of the disassembled battery cell module is good, thereby improving the recycling rate of the battery cell module.

[0047] Specifically, the housing 110 includes a first shell 114 and a second shell 115 that are spliced ​​together, and the first shell 114 and the second shell 115 are identical or substantially identical. The first shell 114 and the second shell 115 are spliced ​​together to form a first side surface 111 and a connecting seam 112, and the disassembly portion 113 is formed on the first shell 114 and the second shell 115, respectively. The disassembly portion 113 can be formed by being recessed inward from the first side surface 111, or the disassembly portion 113 can be convexly disposed on the first side surface 111, and the utility model is not limited thereto.

[0048] Furthermore, the disassembly mechanism 300 includes a driving assembly 310 and a force applying member 320. The driving assembly 310 includes two output ends that can move in opposite directions or toward each other along the first horizontal direction. There are two force applying members 320, which are fixedly connected to different output ends respectively. When the battery pack 100 moves to a position to be disassembled relative to the disassembly mechanism 300, the two force applying members 320 can move in opposite directions and apply disassembly forces to different disassembly parts 113 respectively. The driving assembly 310 can specifically adopt a double-headed cylinder, a double-slider linear motor or a double-slider linear module, etc. In this embodiment, a double-slider linear module is preferably used, which has a simple structure, high moving position accuracy, and reliable force application.

[0049] Preferably, the disassembly portion 113 has a second side surface 1131 perpendicular to the first horizontal direction and facing the force-applying member 320. The second side surface 1131 is preferably recessed inwardly with a snap-in hole 1132. The force-applying member 320 is at least partially snap-fitted with the snap-in hole 1132, thereby improving the tightness of the connection between the force-applying member 320 and the disassembly portion 113 during the disassembly process and ensuring reliable disassembly of the housing 110.

[0050] Since the first shell 114 and the second shell 115 of the shell 110 gradually open in an eight-shaped shape in response to the disassembly of the disassembly mechanism 300, the shell 110 and the disassembly mechanism 300 tend to move away from each other in the second horizontal direction, and when the shell 110 is blocked by the insulating stopper 400, the disassembly portion 113 engaged with the force-applying member 320 will be deformed, and the deformation increases with the increase of the opening angle of the shell 110, resulting in the disassembly portion 113 being broken during the disassembly process, and the shell 110 cannot be disassembled into place.

[0051] As a preferred embodiment, the length of the insulating stop block 400 in the first horizontal direction is sufficient to ensure that when the outer shell 110 is gradually opened, the first side surface 111 can be gradually offset from the insulating stop block 400 in the first horizontal direction, that is, during the opening process of the first shell 114 and the second shell 115, the side of the first shell 114 and the second shell 115 on which the connecting seam 112 is formed can be moved to the outside of the side of the insulating stop block 400 in the first horizontal direction to offset the insulating stop block 400 from the outer shell 110. During disassembly, the outer shell 110 can be moved toward the disassembly mechanism 300 along the second horizontal direction under the traction of the force-applying member 320 to reduce deformation and ensure that the disassembly mechanism 300 can reliably disassemble the outer shell 110 into place.

[0052] Preferably, when the battery pack 100 is in the position to be disassembled, the projection of the connecting seam 112 in the second horizontal direction coincides with the center line of the blocking surface 420 parallel to the vertical direction, so that the battery pack 100 in the position to be disassembled can be reliably abutted against the insulating block 400, and during the disassembly of the battery pack 100, the first shell 114 and the second shell 115 can be staggered with the insulating block 400 at the same time, thereby improving the synchronization of disassembly of the first shell 114 and the second shell 115, and ensuring that the first shell 114 and the second shell 115 are smoothly and reliably opened in an eight-shaped shape.

[0053] Reference Figure 5 and Figure 6As shown, the specific working process of the battery pack disassembly device of the utility model is as follows: initially, the two force-applying members 320 of the driving assembly 310 move toward each other to the first working state, and the operator places the battery pack 100 to be disassembled on the carrier 200, with the first side 111 facing the disassembly mechanism 300; the operator adjusts the position along the first horizontal direction so that the projections of the two force-applying members 320 in the second horizontal direction are both located between the two disassembly parts 113, and then pushes the battery pack 100 along the second horizontal direction so that the shell 110 of the battery pack 100 is against the insulating stopper 400, and the projections of the disassembly part 113 and the force-applying members 320 in the first horizontal direction at least partially overlap, and at this time the battery pack 100 is adjusted to the position to be disassembled relative to the disassembly mechanism 300; the driving assembly 310 is started, and the driving assembly 310 drives the two force-applying members 320 to move back to the second working state. During this process, the force-applying members 320 0 is engaged with the disassembly portion 113, and pushes the disassembly portion 113, so that the first shell 114 and the second shell 115 are gradually opened in an eight-shaped shape. During the opening process of the shell 110, the shell 110 will push the battery module inside it toward the disassembly mechanism 300, and the battery module is blocked by the insulating block 400 to avoid contacting the disassembly mechanism 300. As the opening angle of the shell 110 increases, the shell 110 and the insulating block 400 are staggered to prevent the shell 110 from being blocked by the insulating block 400, ensuring that the force-applying member 320 can reliably disassemble the shell 110; when the force-applying member 320 moves to the second working state, the opening angle of the shell 110 reaches the maximum, and the shell 110 is disassembled. At this time, the driving assembly 310 drives the force-applying member 320 to continue to move back to the first working state and stop, so that the force-applying member 320 is away from the shell 110, and the operator can safely remove the disassembled battery pack 100.

[0054] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
