[0002] CTP (Cell to Pack) batteries are a technology that integrates battery cells directly into a battery pack, eliminating the need for traditional module structures. This technology increases battery integration and brings many advantages, but it also faces some challenges. When a battery malfunctions or is damaged, the battery pack needs to be disassembled for recycling. The first step in disassembling the battery pack is to remove all the countersunk bolts connecting the top cover to the casing, separating the top cover from the casing. Generally, an Allen wrench is used to remove the countersunk bolts; however, due to the large number of countersunk bolts connecting the top cover to the casing, using an Allen wrench increases the labor intensity for workers, is time-consuming and laborious, and has low efficiency, making it unsuitable for batch disassembly of CTP batteries. Utility Model Content

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0017] This utility model provides a device for removing countersunk bolts from the top cover of a CTP battery, the structure of which is as follows: Figure 1 - Figure 2 As shown, the device includes a support mechanism 100, a connecting mechanism 200, and a driving mechanism 300. The bottom of the support mechanism 100 is used to abut against the top surface of the upper cover. The connecting mechanism 200 includes a connector 210 and an elastic member 220. The upper end of the connector 210 is slidably connected to the support mechanism 100 and can move up and down relative to the support mechanism 100. The lower end of the connector 210 is used to mate with the internal hexagonal hole of the countersunk bolt. The elastic member 220 connects the support mechanism 100 and the connector 210 to apply a downward force to the connector 210 and make the bottom of the connector 210 lower than the bottom of the support mechanism 100. The driving mechanism 300 is connected to the support mechanism 100 and is used to drive the support mechanism 100 to rotate, so that the countersunk bolt rotates.

[0018] In use, the lower end of the connector 210 is aligned with the internal hexagonal hole of the countersunk bolt. A downward force is then applied to the drive mechanism 300 until the bottom of the support mechanism 100 abuts against the top surface of the cover. During this process, the connector 210 moves upward due to the upward force exerted on it by the countersunk bolt. The elastic element 220 is in an elastic deformation state and accumulates elastic potential energy, thereby exerting a downward force on the connector 210. By manipulating the drive mechanism 300, the drive mechanism 300 drives the support mechanism 100 to rotate. Because the connector 210 is limited by the support mechanism 100, it can only move up and down relative to the support mechanism 100. When the support mechanism 100 rotates, it drives the connector 210 to rotate, thus causing the countersunk bolt to rotate. During the rotation of the countersunk bolt, it gradually moves towards... The countersunk bolt moves upward until it is removed from the top cover. During the upward movement of the countersunk bolt, it pushes the connector 210 upward, and the elastic element 220 gradually deforms. After the countersunk bolt is removed from the top cover, an upward force is applied to the drive mechanism 300, the bottom of the support mechanism 100 separates from the top surface of the top cover, the elastic element 220 releases its elastic potential energy, and pushes the connector 210 downward. As the support mechanism 100 gradually moves upward, the connector 210 gradually resets. When the connector 210 is fully reset, it separates from the inner hexagonal hole of the countersunk bolt, completing the disassembly of the countersunk bolt. This CTP battery top cover countersunk bolt disassembly device can disassemble the countersunk bolt connecting the top cover and the casing without manual force, which can reduce the labor intensity of workers, save time and effort, and has high efficiency. It is suitable for use when disassembling CTP batteries in batches.

[0019] As a preferred embodiment, please refer to Figure 1 and Figure 2 The support mechanism 100 has a cavity with an open bottom, which is used for the countersunk bolt to move up and down. The connector 210 is disposed in the cavity, and the cavity can guide and limit the countersunk bolt during disassembly to prevent the countersunk bolt from becoming skewed during disassembly.

[0020] As a preferred embodiment, please refer to Figure 1 and Figure 2The support mechanism 100 includes a support member 110 and at least two positioning members 120. Each support member 110 is arranged in a ring array below the support member 110 to enclose and form the cavity. The upper end of each positioning member 120 is connected to the bottom of the support member 110. The upper end of the connecting member 210 is slidably connected to the support member 110. The elastic member 220 connects the support member 110 and the connecting member 210. The driving mechanism 300 is connected to the support member 110. The support member 110 provides support and guidance for the up and down movement of the connecting member 210. The positioning member 120 performs a positioning function by aligning the lower end of the connecting member 210 with the internal hexagonal hole of the countersunk bolt, and then applying a downward force to the driving mechanism 300 until the bottom of the positioning member 120 abuts against the top surface of the cover. When the bottom of the positioning member 120 abuts against the top surface of the cover, the positioning member 120 performs its positioning function.

[0021] As a preferred embodiment, please refer to Figure 2 and Figure 3 The support member 110 has a vertically extending channel 111 with an open bottom. The channel 111 is coaxial with the cavity. At least one keyway 1111 extending along its length and closed at the bottom is formed on the inner wall of the channel 111. The connector 210 includes a sliding shaft 211, at least one key block 212, and a connecting shaft 213. The upper end of the sliding shaft 211 is slidably connected to the channel 111. Each key block 212 is fixedly connected to the upper end of the sliding shaft 211, and each key block 212 is also slidably connected to each keyway 1111. The top of the connecting shaft 213 is coaxially and detachably fixedly connected to the bottom of the sliding shaft 211. The lower end of the connecting shaft 213 is used to connect with a countersunk bolt. The internal hexagonal hole is connected, and the elastic element 220 is disposed in the channel 111 and located above the sliding shaft 211. The upper end of the elastic element 220 is connected to the support 110, and the lower end of the elastic element 220 is connected to the sliding shaft 211. Through the mutual cooperation of the key block 212 and the keyway 1111, the connector 210 can be limited, so that the connector 210 can only move up and down relative to the support 110, but cannot rotate relative to the support 110. When the driving mechanism 300 drives the support 110 to rotate, the connector 210 can follow the support 110 to rotate, thereby driving the countersunk bolt to rotate and realizing the disassembly of the countersunk bolt.

[0022] As a preferred embodiment, please refer to Figure 2 and Figure 3The support member 110 includes a support column 112 and a sealing plate 113. The support column 112 and the sealing plate 113 are coaxially arranged from top to bottom and are detachably and fixedly connected to each other. The upper section of the channel 111 is coaxially opened on the support column 112. The keyway 1111 with a bottom opening is opened on the inner wall of the upper section of the channel 111. The lower section of the channel 111 is coaxially opened on the sealing plate 113. The sealing plate 113 is used to block the bottom opening of the keyway 1111. The sealing plate 113 can be removed from the support column 112 to disassemble and assemble the key block 212 and the elastic member 220. The sealing plate 113 can be fixedly connected to the support column 112 to limit the key block 212 and prevent the key block 212 from falling out of the bottom opening of the keyway 1111 during the up and down movement along the keyway 1111.

[0023] In a preferred embodiment, the sealing plate 113 is detachably connected to the support column 112 via screws.

[0024] In a preferred embodiment, the top of the connecting shaft 213 is detachably and coaxially fixedly connected to the bottom of the sliding shaft 211 via screws, which facilitates the replacement of the model of the connecting shaft 213 and makes the connecting shaft 213 compatible with the internal hexagonal hole of the countersunk bolt.

[0025] As a preferred embodiment, please refer to Figure 2 and Figure 3 The positioning element 120 includes two components, and the support mechanism 100 further includes a drive assembly 130. The drive assembly 130 is connected to the support element 110 and is also connected to the two positioning elements 120. It is used to drive the two positioning elements 120 to move closer to each other or further apart in the horizontal plane, so that the two positioning elements 120 can clamp or loosen the countersunk bolt together. When the countersunk bolt is just taken out from the mounting hole of the top cover, by operating the drive assembly 130, the drive assembly 130 drives the two positioning elements 120 to move closer to each other in the horizontal plane, so that the two positioning elements 120 can clamp the countersunk bolt together, which facilitates the transfer of the countersunk bolt to the recycling position.

[0026] As a preferred embodiment, please refer to Figure 2 and Figure 3The drive assembly 130 includes a bearing 131, a gear ring 132, two guide rails 133, two racks 134, a connecting rod 135, and a telescopic drive component 136. The inner ring of the bearing 131 is fixedly connected to the bottom of the support component 110. The upper end of the connecting component 210 slides through the central hole of the bearing 131. The gear ring 132 is coaxially fixedly sleeved on the outer ring of the bearing 132. The two guide rails 133 are horizontally and oppositely arranged on both sides of the gear ring 132 and are both fixedly connected to the bottom of the support component 110. The two racks 135 and the connecting rod 136 are connected to the outer ring of the bearing 131. The two guide rails 133 are slidably connected in a one-to-one correspondence and both mesh with the gear ring 132. The two racks 134 are also fixedly connected in a one-to-one correspondence with the two positioning members 120. One end of the connecting rod 135 is fixedly connected to one end of one of the racks 134. The fixed end of the telescopic drive member 136 is fixedly connected to the support member 110, and the telescopic end of the telescopic drive member 136 is fixedly connected to the other end of the rack 134. This is used to drive the connecting rod 135 to move horizontally reciprocatingly. During the rotation of the countersunk bolt, it will gradually move upward until it moves from the top... When the countersunk bolt is removed from the upper cover, the telescopic drive 136 is activated, and its telescopic end shortens, driving the connecting rod 135 to move horizontally. This, in turn, causes the corresponding rack 134 to move horizontally. Since both racks 134 are engaged with the toothed ring 132, when one rack 134 moves, according to the meshing transmission principle, the other rack 134 will move synchronously in the opposite direction. This causes the two positioning members 120 to move closer to each other until the lower ends of the two positioning members 120 clamp the countersunk bolt together. When the countersunk bolt is moved to the retraction position, the telescopic drive 136 is activated, and the telescopic end of the telescopic drive 136 extends, which can drive the connecting rod 135 to move horizontally, thereby driving the corresponding rack 134 to move horizontally. Since both racks 134 are engaged with the toothed ring 132, when one rack 134 moves, according to the meshing transmission principle, the other rack 134 will move synchronously in the opposite direction, thereby driving the two positioning members 120 to move away from each other until the lower ends of the two positioning members 120 loosen the countersunk bolt together.

[0027] As a preferred embodiment, please refer to Figure 2 The elastic element 220 is a spring, which can accumulate elastic potential energy when subjected to pressure, and release elastic potential energy when the pressure is removed.

[0028] As a preferred embodiment, please refer to Figure 2The driving mechanism 300 is a rotary driving member. The output end of the rotary driving member is fixedly connected to the support member 110 and is used to drive the support member 110 to rotate around the central axis of the cavity. When the output end of the rotary driving member rotates, it can drive the support member 110 to rotate, thereby driving the two positioning members 120 to rotate along with it via the driving assembly 130, and also driving the connecting member 210 to rotate synchronously.

[0029] As a preferred embodiment, the CTP battery cover countersunk bolt removal device further includes a moving mechanism connected to the driving mechanism 300, which drives the driving mechanism 300 to move in the X, Y and Z directions so that the connector 210 reaches the target position. This enables the self-disassembly and self-transfer of the countersunk bolt without manual intervention. The moving mechanism is not shown in the figure.

[0030] In a preferred embodiment, the moving mechanism includes an X-axis moving component, a Y-axis moving component, and a Z-axis moving component. The X-axis moving component is connected to the driving mechanism 300 and is used to drive the driving mechanism 300 to move in the X direction. The Y-axis moving component is connected to the X-axis moving component and is used to drive the X-axis moving component to move in the Y direction. The Z-axis moving component is connected to the Y-axis moving component and is used to drive the Y-axis moving component to move in the Z direction. By manipulating the X-axis moving component, the driving mechanism 300 can be moved in the X direction. By manipulating the Y-axis moving component, the X-axis moving component can be moved in the Y direction. By manipulating the Z-axis moving component, the Y-axis moving component can be moved in the Z direction. This allows the connector 210 to reach the target position, realizing the self-disassembly and self-transfer process of the countersunk bolt without manual intervention.

[0031] In a preferred embodiment, the X-direction moving component includes an X-direction crossbar and an X-direction moving member. The X-direction crossbar is horizontally arranged along the X-direction, and the X-direction moving member is slidably connected to the X-direction crossbar and can reciprocate along the X-direction crossbar. The X-direction moving member is also fixedly connected to the driving mechanism 300. When the X-direction moving member is activated, it can reciprocate along the X-direction crossbar and drive the driving mechanism 300 to move in the X-direction.

[0032] In a preferred embodiment, the X-axis moving member is a first linear motor.

[0033] In a preferred embodiment, the Y-direction moving component includes a Y-direction crossbar and a Y-direction moving member. The Y-direction crossbar is horizontally arranged along the Y-direction, and the Y-direction moving member is slidably connected to the Y-direction crossbar and can reciprocate along the Y-direction crossbar. The Y-direction moving member is also fixedly connected to one end of the X-direction crossbar. By manipulating the Y-direction moving member, the Y-direction moving member can reciprocate along the Y-direction crossbar, which can drive the X-direction crossbar to move in the Y-direction, thereby enabling the driving mechanism 300 to move in the Y-direction.

[0034] In a preferred embodiment, the Y-axis moving member is a second linear motor.

[0035] In a preferred embodiment, the Z-axis moving component includes a Z-axis upright and a Z-axis moving member. The Z-axis upright is vertically arranged along the Z-axis. The Z-axis moving member is slidably connected to the Z-axis upright and can reciprocate along the Z-axis upright. The Z-axis moving member is also fixedly connected to one end of the Y-axis crossbar. When the Z-axis moving member is activated, it can reciprocate along the Z-axis upright, driving the Y-axis crossbar to move in the Z-axis direction, thereby enabling the driving mechanism 300 to move in the Z-axis direction.

[0036] In a preferred embodiment, the Z-axis moving component is a third linear motor.

[0037] As a preferred embodiment, the CTP battery cover countersunk bolt removal device further includes a detection mechanism connected to the support mechanism 100 to detect the position of the countersunk bolt, so that the moving mechanism can drive the driving mechanism 300 to move in the X, Y and Z directions, so that the connector 210 reaches the position of the countersunk bolt.

[0038] In a preferred embodiment, the detection mechanism includes a detection head and a controller. The detection head is connected to the support member 110 and is used to detect the position of the countersunk bolt. The controller is electrically connected to the rotation drive member, the telescopic drive member 136, the X-axis moving member, the Y-axis moving member, and the Z-axis moving member.

[0039] To better understand this utility model, the following is combined with... Figure 1 - Figure 3 The working principle of the technical solution of this utility model will be described in detail below: In use, the lower end of the connecting shaft 213 is aligned with the internal hexagonal hole of the countersunk bolt. The Z-axis moving component is activated, moving downwards along the Z-axis upright, driving the Y-axis crossbar to move downwards in the Z-axis direction. This, in turn, causes the rotational driving component to move downwards in the Z-axis direction until the bottom of the positioning component 120 abuts against the top surface of the upper cover. During this process, the connecting shaft 213 moves upwards due to the upward force exerted on it by the countersunk bolt. The elastic component 220 is in an elastic deformation state and accumulates elastic potential energy, thereby exerting a downward force on the connecting shaft 213. The rotational driving component is activated, and its output end rotates, driving the support component 110. Due to the key... The cooperation between block 212 and the keyway 1111 restricts the sliding shaft 211, which in turn restricts the connecting shaft 213. The connecting shaft 213 can only move up and down relative to the support member 110. When the support member 110 rotates, it drives the connecting shaft 213 to rotate, thereby causing the countersunk bolt to rotate. During the rotation of the countersunk bolt, it gradually moves upward until it moves out of the upper cover. During the upward movement of the countersunk bolt, it pushes the connecting shaft 213 upward, and the deformation of the elastic member 220 gradually increases. When the countersunk bolt moves out of the upper cover, the Z-axis moving member is activated. The Z-axis moving member can move upward along the Z-axis upright, which can drive the Y-axis crossbar to move upward in the Z-axis direction, thereby... The rotating drive component can move inward and upward in the Z direction, the bottom of the positioning component 120 separates from the top surface of the cover, the elastic component 220 releases elastic potential energy, pushing the connecting shaft 213 downward. As the support component 110 gradually moves upward, the connecting shaft 213 gradually returns to its original position. When the connecting shaft 213 is fully returned to its original position, it separates from the internal hexagonal hole of the countersunk bolt, completing the disassembly of the countersunk bolt. When the countersunk bolt is just removed from the mounting hole of the cover, the telescopic drive component 136 is activated, and the telescopic end of the telescopic drive component 136 shortens, which can drive the connecting rod 135 to move horizontally, driving the corresponding rack 134 to move horizontally. Since both racks 134 are engaged with the gear ring 132, when one of them... When rack 134 moves, according to the meshing transmission principle, the other rack 134 will move synchronously in the opposite direction, thereby driving the two positioning members 120 to move closer to each other until the lower ends of the two positioning members 120 clamp the countersunk bolt together. After the countersunk bolt is moved to the retracted position, the telescopic drive 136 is activated, and the telescopic end of the telescopic drive 136 extends, which can drive the connecting rod 135 to move horizontally, driving the corresponding rack 134 to move horizontally. Since both racks 134 are engaged with the gear ring 132, when one rack 134 moves, according to the meshing transmission principle, the other rack 134 will move synchronously in the opposite direction, thereby driving the two positioning members 120 to move away from each other.The countersunk bolts are loosened until the lower ends of the two positioning parts 120 are simultaneously disengaged, allowing them to cooperate with the moving mechanism to move the countersunk bolts to the recycling position. This CTP battery cover countersunk bolt disassembly device removes the countersunk bolts connecting the cover and the casing without manual force, reducing labor intensity, saving time and effort, and offering high efficiency. It is suitable for batch disassembly of CTP batteries.

[0040] The CTP battery cover countersunk bolt removal device provided by this utility model has the following beneficial effects: (1) When the countersunk bolt is just removed from the mounting hole of the top cover, the telescopic drive 136 is activated, and the telescopic end of the telescopic drive 136 is shortened, which can drive the connecting rod 135 to move horizontally, thereby driving the corresponding rack 134 to move horizontally. Since both racks 134 are engaged with the toothed ring 132, when one rack 134 moves, according to the meshing transmission principle, the other rack 134 will move synchronously in the opposite direction, thereby driving the two positioning members 120 to move closer to each other until the lower ends of the two positioning members 120 clamp the countersunk bolt together; when the countersunk bolt is transferred to the recycling area After positioning, the telescopic drive 136 is activated, and the telescopic end of the telescopic drive 136 extends, which can drive the connecting rod 135 to move horizontally, thereby driving the corresponding rack 134 to move horizontally. Since both racks 134 are engaged with the toothed ring 132, when one rack 134 moves, according to the meshing transmission principle, the other rack 134 will move synchronously in the opposite direction, thereby driving the two positioning members 120 to move away from each other until the lower ends of the two positioning members 120 loosen the countersunk bolt together, so that it can cooperate with the moving mechanism to move the countersunk bolt to the recycling position. (2) The moving mechanism drives the driving mechanism 300 to move in the X, Y and Z directions so that the connecting piece 210 reaches the target position, which can realize the self-disassembly and self-transfer of the countersunk bolt without manual intervention; (3) The countersunk bolt removal device for the CTP battery cover can be used to remove the countersunk bolts connecting the cover and the box without manual force, which can reduce the labor intensity of workers, save time and effort, and has high efficiency. It is suitable for use when disassembling CTP batteries in batches.
