Battery pack disassembly mechanism

Abstract

The application discloses a battery pack disassembling mechanism. The battery pack disassembling mechanism comprises a base, a bearing assembly and a cutting tool. The bearing assembly comprises a bearing platform suitable for bearing the battery pack. The cutting tool is reciprocatingly vibrated on the base and located at one side of the bearing platform. The cutting tool has a blade surface and a back blade surface arranged oppositely. When the cutting tool moves in a first direction, the blade surface is driven to approach the battery pack on the bearing platform and cut the battery pack. When the cutting tool moves in a second direction, the back blade surface is in contact with the battery pack to drive the cutting tool to move away from the battery pack. The first direction and the second direction are arranged oppositely. The vibrating cutting tool provided by the application can set a lower linear velocity of the cutting tool and more easily control the cutting amount. When the cutting tool is in contact with the battery pack, the contact friction temperature is lower, so it is relatively safer. Moreover, the back blade surface can not directly process the battery pack, and the cutting tool can be better protected.

Description

Technical Field

[0001] This invention relates to the technical field of battery processing mechanisms, and more specifically to a battery pack disassembly mechanism. Background Technology

[0002] A battery pack typically includes battery cells, a battery protection board, battery connectors, and an outer casing. After prolonged use, the battery cells gradually lose their lifespan and can no longer power electrical devices, necessitating replacement or maintenance for recycling and preventing battery contamination. Maintenance or recycling requires disassembling the battery pack, specifically removing the outer casing, to access and recycle the internal components. Currently, most battery packs are manually disassembled using handheld grinders or cutters, resulting in low efficiency. Furthermore, the disc-shaped cutting tool generates high linear speeds during rotation, easily damaging the battery cells. The high temperature of the cutting tool, especially at the cut point on the outer casing, or upon accidental contact with a battery cell, can lead to short circuits, fires, or even explosions, posing a significant operational risk. Additionally, the small cutting opening of the disc-shaped tool generates considerable debris, contaminating other components. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is that the traditional method of disassembling battery packs is inefficient, has poor disassembly effect, and poses operational risks.

[0007] A cutting tool is reciprocatingly mounted on the base and located on one side of the support platform. The cutting tool has a cutting edge and a back edge that are facing away from each other. When the cutting tool moves in a first direction, the cutting edge can be driven to approach the battery pack on the support platform and cut it. When the cutting tool moves in a second direction, the back edge can come into contact with the battery pack to drive the cutting tool to move away from the battery pack.

[0015] A transmission component is connected to the cutting component, and the transmission component is provided with a transmission part that cooperates with the driving part;

[0016] The first driver drives the drive unit to move, and under the cooperation of the drive unit and the transmission unit, the transmission member can be driven to reciprocate along the vertical direction of the base, thereby driving the cutting member to reciprocate along the vertical direction of the base.

[0017] Optionally, the transmission component includes a transmission rod, the transmission part includes a first elongated hole provided on the transmission rod, the first elongated hole extending laterally along the base; the driving part includes a transmission cam provided on the first driver, the transmission cam being sleeved in the first elongated hole;

[0018] The base includes a base plate and a side plate standing on the base plate. The cutting drive structure also includes a guide rod disposed on the side plate. The first driver is disposed on the side plate. The guide rod extends along the vertical direction of the base. One end of the transmission rod is connected to the cutting component, and the other end of the transmission rod is slidably sleeved on the outside of the guide rod.

[0019] Optionally, the cutting element includes:

[0020] A tool holder extends along the vertical direction of the base and is slidably sleeved with the transmission member along the lateral direction of the base; the elastic member connects the tool holder and the transmission member.

[0021] The blade is mounted on the blade holder.

[0022] Optionally, multiple blades are provided, and the multiple blades are arranged at intervals along the vertical direction of the blade holder;

[0023] Each of the blades is positioned with its cutting edge facing downwards;

[0024] In the transverse direction along the base, the back edge of each blade extends downward at an angle; and / or, in the transverse direction along the base, the end of each blade edge away from the blade holder extends downward at an angle.

[0025] Optionally, the tool holder is provided with a through hole that extends laterally through the base, one end of the transmission member is slidably sleeved in the through hole, and the transmission member is provided with two stop portions, which are respectively located at both ends of the through hole, so as to restrict the movement of the tool holder in the lateral direction of the base.

[0026] Optionally, the battery pack disassembly mechanism further includes a cutting limiting mechanism, which is used to adjust the cutting amount of the cutting tool.

[0027] Optionally, the cutting limiting mechanism includes a limiting plate movably disposed on the base. The limiting plate is located on one side of the bearing platform along the longitudinal direction of the base and is spaced apart from the blade of the cutting tool along the longitudinal direction of the base to form a cutting gap. An adjustment part is provided on one side of the limiting plate, and a mating part is provided on the base. The adjustment part and the mating part cooperate to adjust the size of the cutting gap.

[0028] Optionally, the support platform is movably mounted on the base and has at least a travel distance towards and away from the cutting tool;

[0030] The battery pack disassembly mechanism also includes a locking mechanism, which is located on the support platform and is used to lock and fix the battery pack to the support platform.

[0031] The technical solution provided by this invention has the following advantages:

[0032] The battery pack disassembly mechanism provided by this invention includes a base, a support component and a cutting tool disposed on the base. The support component supports the battery pack, placing it at a certain height. The cutting tool cuts the battery pack on the support component to cut open the outer packaging of the battery pack. Furthermore, the cutting tool performs vibratory reciprocating cutting, and its movement is reciprocating. Compared to a rotary cutting tool, the linear speed of the vibratory cutting tool can be set lower, the cutting amount is easier to control, and the lower linear speed results in lower contact friction temperature when the cutting tool contacts the battery pack, thus making it relatively safer. Moreover, the cutting tool cuts through its blade surface, and when the cutting tool moves in the reverse direction, its back edge surface can contact the battery pack, thereby keeping the cutting tool away from the battery pack and preventing damage to the cutting tool caused by direct processing of the battery pack with the back edge surface. This better protects the cutting tool and extends the service life of the battery pack disassembly mechanism. Attached Figure Description

Detailed Implementation

[0044] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0045] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0046] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0047] This invention provides a battery pack disassembly mechanism 100, which is applicable to disassembling the outer packaging of a battery pack 200. The same battery pack 200 may require multiple cuts to ensure that each side of the battery pack 200 can be cut and disassembled by the battery pack disassembly mechanism 100. Preferably, when the battery pack 200 is approximately square, the battery pack disassembly mechanism 100 can cut at each side of the battery pack 200 to ensure that each surface of the battery pack 200 can be better separated, thereby ensuring a better disassembly effect. For ease of explanation, the specific structure of the battery pack disassembly mechanism 100 will be described below using a square battery pack 200 as an example.

[0048] Specifically, please refer to Figures 1 to 3 The battery pack disassembly mechanism 100 includes a base 1, a support assembly 2 and a cutting tool 3 disposed on the base 1. The support assembly 2 includes a support platform 21 adapted to support the battery pack 200. The cutting tool 3 is reciprocatingly disposed on the base 1 and located on one side of the support platform 21. The cutting tool 3 has a cutting edge 3121 and a back cutting edge 3122 arranged opposite to each other. When the cutting tool 3 moves along a first direction, the cutting edge 3121 can be driven to approach the battery pack 200 on the support platform 21 and cut it. When the cutting tool 3 moves along a second direction, the back cutting edge 3122 can come into contact with the battery pack 200 to drive the cutting tool 3 to move away from the battery pack 200. The first direction and the second direction are arranged opposite to each other.

[0049] This invention places the battery pack 200 at a certain height on a support platform 21. The cutting tool 3 can cut the battery pack 200 on the support platform 21 to cut open the outer packaging of the battery pack 200. Moreover, the cutting tool 3 moves in a vibrating reciprocating motion. Compared with a rotary cutting tool 3, the linear speed of the vibrating cutting tool 3 can be set to be lower, so the cutting amount is easier to control. In addition, the lower linear speed results in a lower contact friction temperature when the cutting tool 3 comes into contact with the battery pack 200, which is relatively safer. Furthermore, the cutting tool 3 cuts through the blade surface 3121. When the cutting tool 3 moves in the reverse direction, the back blade surface 3122 can come into contact with the battery pack 200, thereby keeping the cutting tool 3 away from the battery pack 200 as a whole. This avoids the back blade surface 3122 directly processing the battery pack 200 and causing damage to the cutting tool 3, which can better protect the cutting tool 3 and extend the service life of the battery pack disassembly mechanism 100.

[0050] The shape of the base 1 is not specifically limited. For example, the base 1 can be a frame made of steel pipes, or it can be a mounting base in a broad sense, such as the ground. Alternatively, the base 1 can be a single plate or multiple plates joined together, or it can be multiple plates or supports arranged independently. Preferably, the base 1 is flat to make other components placed on it more stable. Furthermore, in combination with... Figure 3 As shown, the base 1 can be rectangular, having a long side and a short side. The long side is along the length direction of the base 1, and the short side is along the width direction of the base 1. When the battery pack disassembly mechanism 100 is operating normally, the length direction of the base 1 is set along the left-right direction, and the width direction of the base 1 is set along the front-back direction. Unless otherwise specified, all descriptions of orientation in this invention shall be taken as such.

[0051] It is understood that the cutting direction of the cutting blade 3 is not specifically limited and can be set according to the specific shape of the battery pack 200. For example, the cutting blade 3 can move back and forth along the vertical direction of the base 1 to make cuts; or, the cutting blade 3 can move back and forth along the horizontal direction of the base 1 to make cuts; or, the cutting blade 3 can move back and forth along the front-to-back direction of the base 1 to make cuts; multiple sets of cutting blades 3 can also be provided, and multiple sets of cutting blades 3 can move in the front-to-back direction, the horizontal direction, or the vertical direction respectively. The number and position of the cutting blades 3 can be reasonably set according to the actual size of the battery pack 200, and are not limited in detail here.

[0052] Preferably, combined with Figure 3 and Figure 4As shown, a set of cutting tools 3 is provided, which makes the cutting cost lower and easier to operate. Specifically, the cutting tool 3 includes a cutting element 31, a cutting drive structure 32, and an elastic element 33. The cutting element 31 has a reciprocating stroke along the vertical direction of the base 1, and the outer packaging of the battery pack 200 is cut by the reciprocating vibration of the cutting element 31. The cutting drive structure 32 is connected to the cutting element 31 and is used to drive the cutting element 31 to move reciprocally along the vertical direction of the base 1. The elastic element 33 connects the cutting element 31 and the cutting drive structure 32, so that when the cutting element 31 moves reciprocally, the cutting element 31 has a certain amount of movement in the horizontal direction, so as to avoid the back edge 3122 of the cutting element 31 colliding with the battery pack 200 and causing damage. The cutting element 31 is provided with a guide part. When the cutting drive structure 32 drives the cutting element 31 to move upward along the base 1, the guide part interacts with the battery pack 200 on the support platform 21. The contact action drives the cutting element 31 to move away from the battery pack 200, thus preventing the back edge 3122 from directly processing the battery pack 200 and causing damage, and better protecting the cutting element 31. At this time, the elastic element 33 is in an elastic energy storage state. When the cutting drive structure 32 drives the cutting element 31 to move downward along the base 1, under the action of the elastic restoring force of the elastic element 33, the cutting element 31 can move towards the battery pack 200 and cut the battery pack 200. When the cutting element 31 is cutting the battery pack 200, it can get closer to the battery pack 200 better under the action of the elastic element 33. When the back edge 3122 of the cutting element 31 moves, it can move away from the battery pack 200, thereby better protecting the cutting element 31 and extending the service life of the battery pack disassembly mechanism 100.

[0053] More preferably, the cutting element 31 is configured to cut when moving downwards and to reset when moving upwards. The elastic element 33 can be configured as a telescopic spring.

[0054] The cutting drive structure 32 is used to drive the cutting piece 31 to move along the vertical direction of the frame, so as to achieve continuous cutting by the cutting piece 31. In one embodiment, the cutting drive structure 32 can be configured as a drive cylinder, which directly drives the cutting piece 31 to reciprocate along the vertical direction of the frame, thereby cutting the outer packaging of the battery pack 200.

[0055] Preferably, combined with Figure 4 and Figure 5As shown, the cutting drive structure 32 includes a first driver 321 and a transmission component. The first driver 321 is provided with a driving part; the transmission component is connected to the cutting component 31, and a transmission part that cooperates with the driving part is provided on the transmission component; the first driver 321 drives the driving part to move, and under the cooperation of the driving part and the transmission part, the transmission component can be driven to move back and forth in the vertical direction of the base 1, thereby driving the cutting component 31 to move back and forth in the vertical direction of the base 1 to cut the battery pack 200. Moreover, through the transmission of the transmission component, the vibration frequency and vibration amplitude of the cutting component 31 can be better controlled, and the cutting adjustment of the battery pack disassembly mechanism 100 is more flexible and can better adapt to the disassembly requirements of different battery packs 200.

[0056] Furthermore, combined Figure 6 and Figure 7 As shown, the transmission component includes a transmission rod 322, which is elongated and has a first end and a second end along its length. The length of the transmission rod 322 extends along the left-right direction of the base 1. The transmission part includes a first elongated hole 3221 on the transmission rod 322, which extends laterally along the base 1. The driving part includes a transmission cam 3211 on the first driver 321, which is fitted inside the first elongated hole 3221. The base 1 includes a base plate 11 and a side plate 12 standing on the base plate 11. The cutting drive structure 32 also includes a guide rod 323 on the side plate 12. The first driver 321 is on the side plate 12, and the guide rod 323 extends vertically along the base 1. The first end of the transmission rod 322 is connected to the cutting component 31, and the second end of the transmission rod 322 is slidably fitted on the outside of the guide rod 323. The first driver 321 drives the transmission cam 3211 to rotate. The transmission cam 3211 can abut against the first elongated hole 3221, so that the transmission rod 322 can move up and down along the guide rod 323, driving the cutting piece 31 to move along the up and down direction of the base 1, so that the cutting piece 31 can reciprocate to cut.

[0057] The cutting drive structure 32 also includes a guide seat, which is mounted on the side plate 12. A guide rod 323 is fixed to the guide seat and extends vertically. A transmission rod 322 is slidably sleeved on the outside of the guide rod 323 and can move vertically along the guide rod 323. Preferably, two guide rods 323 are provided, arranged parallel to each other in the left-right direction. Two guide seats are also provided, each located at one end of the two guide rods 323 in the vertical direction. The transmission rod 322 slidably sleeved on the two guide rods 323 makes the transmission rod 322 more stable and less prone to wobbling when moving vertically.

[0058] Furthermore, the tool holder 311 is provided with a through hole 3111 extending laterally along the base 1. The first end of the transmission member is slidably sleeved within the through hole 3111, and the transmission member is provided with two stop portions 3112, which are located at both ends of the through hole 3111, to limit the movement of the tool holder 311 in the lateral direction along the base 1. This prevents the tool holder 311 from moving too far away from the battery pack 200, which would make it difficult to cut effectively after recovery. It also prevents the tool holder 311 from getting too close to the battery pack 200, thus affecting the cutting depth. The stop portion 3112 may include a protrusion on the transmission rod 322. The two protrusions are used to abut against both ends of the through hole 3111 when the tool holder 311 moves laterally to its limit position, thereby controlling the movement stroke of the tool holder 311. The protrusion may be integrally formed with the transmission rod 322, or at least one of the protrusions may be detachably connected to the transmission rod 322 to facilitate the assembly and connection of the transmission rod 322 and the tool holder 311.

[0059] For cut part 31, combined Figure 5 and Figure 6 As shown, the cutting component 31 includes a cutter holder 311 and a blade 312. The cutter holder 311 is elongated and extends along the vertical direction of the base 1. The cutter holder 311 is slidably sleeved with the transmission component along the transverse direction of the base 1. An elastic element 33 connects the cutter holder 311 and the transmission component; that is, the two ends of a telescopic spring are arranged in the left-right direction, allowing the cutter holder 311 to have a left-right travel relative to the transmission component, thus preventing the back cutting surface 3122 from machining the battery pack 200 and better protecting the blade 312. The blade 312 is mounted on the cutter holder 311, and at least a portion of the blade 312 protrudes from the cutter holder 311. The blade 312 cuts the battery pack 200 through the portion protruding from the cutter holder 311, preventing collision between the cutter holder 311 and the battery pack 200 and ensuring a better cutting effect.

[0060] Preferably, multiple blades 312 are provided, and the multiple blades 312 are arranged at intervals along the vertical direction of the blade holder 311. The cutting edge 3121 of each blade 312 is set downward. When the blade holder 311 moves downward, it can drive multiple blades 312 to move downward simultaneously to cut the battery pack 200 through the cutting edge 3121. Thus, the cut battery pack 200 outer packaging is in sheet form, which is less likely to form powder that pollutes the usage environment, and it is easier to recycle the cut waste.

[0061] More preferably, such as Figure 8As shown, in the transverse direction along the base 1, the back edge surface 3122 of each blade 312 extends downward at an incline to form the aforementioned guide portion. That is, the back edge surface 3122 is inclined along the vertical direction of the base 1. When the back edge surface 3122 moves upward, the inclined surface of the back edge surface 3122 interacts with the battery pack 200, thereby applying an outward force to the back edge surface 3122 through the battery pack 200, driving the back edge surface 3122 to move away from the battery pack 200, so that the entire cutting piece 31 moves away from the battery pack 200, thereby avoiding the back edge surface 3122 from processing the battery pack 200. When the blade holder 311 moves downward, under the action of the elastic restoring force of the elastic member 33, the cutting piece 31 can be driven to move closer to the battery pack 200, so that the blade surface 3121 can better contact the battery pack 200 for cutting.

[0062] Moreover, combined Figure 8 As shown, in the transverse direction along the base 1, each cutting edge 3121 extends downward at the end away from the blade holder 311, so that the cutting end of the cutting edge 3121 protrudes more from the blade 312 body, thereby increasing the cutting efficiency.

[0063] In one embodiment, the battery pack disassembly mechanism 100 further includes a cutting limiting mechanism 4, which is used to adjust the cutting amount of the cutting tool 3, that is, the cutting width of the cutting tool 3 on the battery pack 200, to avoid the cutting amount being too small and failing to cut open the outer packaging, and also to avoid the cutting amount being too large and cutting into the battery cells inside the battery pack 200.

[0064] Preferably, combined with Figure 2 and Figure 3 As shown, the cutting limiting mechanism 4 includes a limiting plate 41 movably mounted on the base 1. The limiting plate 41 is located on one side of the bearing platform 21 along the longitudinal direction of the base 1 and is spaced apart from the blade 312 of the cutting tool 3 along the longitudinal direction of the base 1 to form a cutting gap x. An adjustment part is provided on one side of the limiting plate 41, and a mating part is provided on the base 1. The adjustment part and the mating part cooperate to adjust the size of the cutting gap x. The limiting plate 41 is generally flat and is arranged parallel to and spaced apart from the side plate 12. The mating part is provided on the side plate 12. The cutting gap can be adjusted by adjusting the distance between the limiting plate 41 and the side plate 12.

[0065] When the battery pack 200 is placed on the support platform 21, one side of the battery pack 200 can be pressed against the limiting plate 41. When the cutting tool 3 is cutting, the cutting amount is the distance between the blade 312 and the side of the battery pack 200 that is pressed against the limiting plate 41. By adjusting the position of the limiting plate 41, the distance between the blade 312 and the side of the battery pack 200 can be adjusted, thereby adjusting the cutting amount of the battery pack 200.

[0066] Preferably, such as Figure 3 As shown, the adjustment part includes an adjustment arm 42 protruding from the limiting plate 41 and a second elongated hole 421 on the adjustment arm 42. The adjustment arm 42 extends toward the side plate 12 and at least partially overlaps the side plate 12. The second elongated hole 421 extends along the direction of the adjustment arm 42. The mating part includes a mounting hole on the side plate 12. The battery pack disassembly mechanism 100 also includes a connector. The connector passes through the second elongated hole 421 and the mounting hole to connect and fix the limiting plate 41 and the side plate 12. The connector is connected to different positions of the second elongated hole 421, thereby adjusting the distance between the limiting plate 41 and the side plate 12 to adjust the cutting amount of the cutting tool 3 on the battery pack 200. The connector can be a connecting screw or a connecting bolt.

[0067] Furthermore, in one embodiment, the support platform 21 can be movably mounted on the base 1 and has at least a travel distance to and from the cutting tool 3; the battery pack disassembly mechanism 100 also includes a platform drive structure 22, which is mounted on the base 1 and connected to the support platform 21, for driving the support platform 21 to move closer to or further away from the support platform 21. By driving the support platform 21 to move through the platform drive structure 22, the battery pack 200 placed on the support platform 21 can actively move closer to the cutting tool 3, making cutting easier and more efficient.

[0068] Preferably, when the cutting tool 3 is located on the left side of the support platform 21, the support platform 21 has at least a travel in the left-right direction along the base 1, and the platform drive structure 22 is used to drive the support platform 21 to move in the left-right direction along the base 1 to get closer to or away from the cutting tool 3.

[0069] Among them, combined Figure 1 and Figure 3 As shown, the platform drive structure 22 includes a second driver 221, which is connected to the carrier platform 21. A slide rail 111 is provided on one of the base 1 and the carrier platform 21, and a slider that slides in cooperation with the slide rail 111 is provided on the other. Under the guidance of the slide rail 111 and the slider, the carrier platform 21 is more stable when moving in the left and right direction along the base 1, thereby making the battery pack 200 more stable and the cutting effect better.

[0070] In addition, the battery pack disassembly mechanism 100 also includes a locking mechanism 5, which is located on the support platform 21 and is used to lock and fix the battery pack 200 on the support platform 21 to prevent the battery pack 200 from sliding during cutting, thereby making the cutting accuracy of the battery pack 200 higher.

[0071] Specifically, in combination Figure 2 and Figure 3As shown, the locking mechanism 5 includes a support plate 51, a first adjusting rod 52, a locking plate 53, and a second adjusting rod 54. The support plate 51 protrudes from the bearing platform 21 and can be integrally formed with the bearing platform 21, standing sideways on the side opposite to the limiting plate 41, or standing sideways on the side of the bearing platform 21 along the left-right direction. One end of the first adjusting rod 52 is connected to and cooperates with the first connecting part and can move relative to the first connecting part; the locking plate 53 is provided at the other end of the first adjusting rod 52 and has a second connecting part; the second adjusting rod 54 is connected to and cooperates with the second connecting part and can move relative to the locking plate 53 along the up-down direction of the base 1.
