Description

Technical Field

[0001] The present application relates to the technical field of lithium battery production equipment, and in particular to a battery cell module clamping device. Background Art

[0002] A battery module is composed of multiple stacked cells. To protect the cells, end plates with insulating covers are typically installed at each end of the module's length. After the end plates are installed, the module with the end plates is moved to a steel strapping station, where the strapping secures the stacked cells and end plates together.

[0003] At present, the stacked battery cells and end plates are generally transported to the steel belt bundling station together through a transport mechanism. The transport mechanism drives the two clamping components to move closer or farther away from each other through a cylinder to clamp or release the stacked battery cells. Although this can achieve the transportation of the battery cell module, if the transport mechanism fails during the transportation process and suddenly stops, the battery cell module will impact the clamping component due to inertia. If the inertia of the battery cell module is greater than the thrust of the cylinder, the battery cell module will easily push the clamping component away and fall off, resulting in low safety and reliability. Utility Model Content

[0004] The purpose of this application is to provide a battery cell module clamping device to solve the problem of low safety and reliability of existing battery cell module clamping devices.

The two first clamping parts are used to clamp or release the battery cell module. The driving end of the first driving mechanism is connected to the two first clamping parts or one of the first clamping parts.

[0008] The first driving mechanism is configured to drive the two first clamping parts toward each other to clamp two opposite sides of the battery cell module extending along the second direction, and the first driving mechanism is further configured to drive the two first clamping parts away from each other to release the battery cell module clamped by the two first clamping parts, wherein the second direction is perpendicular to the first direction in a horizontal plane;

[0009] The locking mechanism is configured to lock the two first clamping parts relative to the base after the two first clamping parts clamp the battery core module.

[0010] The battery cell module clamping device proposed in the present application is provided with a locking mechanism. After the two first clamping parts clamp the battery cell module, the two first clamping parts are locked relative to the base through the locking mechanism, thereby ensuring that the battery cell module will not push the two first clamping parts apart due to the inertia of the battery cell module impacting the first clamping mechanism during transportation, thereby greatly improving the stability and safety and reliability of the battery cell module clamping device in clamping the battery cell module.

[0022] By setting up the lifting member and the elastic member, it is achieved that when the first clamping part is locked relative to the base, the lock head and the rack are always in a meshing state under the action of elastic force, thereby preventing the driving end of the cylinder from being impacted or the lock teeth of the lock head from disengaging from the rack when the cylinder is accidentally powered off, further ensuring the reliability of the locking assembly in locking the first clamping part relative to the base.

[0023] Optionally, the first locking portion further includes a limit block and a guide sleeve, wherein:

[0060] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0061] A battery module is composed of multiple stacked cells. To protect the cells, end plates with insulating covers are typically installed at each end of the module's length. After the end plates are installed, the module with the end plates is moved to a steel strapping station, where the strapping secures the stacked cells and end plates together.

[0062] At present, the stacked battery cells and end plates are generally transported to the steel belt bundling station together through a transport mechanism. The transport mechanism drives the two clamping components to move closer or farther away from each other through a cylinder to clamp or release the stacked battery cells. Although this can achieve the transportation of the battery cell module, if the transport mechanism fails during the transportation process and suddenly stops, the battery cell module will impact the clamping component due to inertia. If the inertia of the battery cell module is greater than the thrust of the cylinder, the battery cell module will easily push the clamping component away and fall off, resulting in low safety and reliability.

[0063] Therefore, this application provides a battery module clamping device, please refer to Figures 1 to 3 As shown, the battery module clamping device proposed in the embodiment of the present application includes a base 10, a first driving mechanism 20, a first clamping mechanism 30 and a locking mechanism 40. The first clamping mechanism 30 includes two first clamping parts 31 arranged in parallel. The two first clamping parts 31 can be arranged in a first direction ( Figure 1 The two first clamping parts 31 are arranged under the base 10 to be close to or away from each other in the X direction in the first direction. The two first clamping parts 31 are used to clamp or release the battery module 50. The driving end of the first driving mechanism 20 is connected to the two first clamping parts 31 or one of the first clamping parts 31. The first driving mechanism 20 is configured to drive the two first clamping parts 31 to move closer to each other to clamp the battery module 50 along the second direction ( Figure 1 The first driving mechanism 20 is further configured to drive the two first clamping parts 31 away from each other to release the battery cell module 50 clamped by the two first clamping parts 31, and the second direction is perpendicular to the first direction in the horizontal plane; the locking mechanism 40 is configured to lock the two first clamping parts 31 relative to the base after the two first clamping parts 31 clamp the battery cell module 50.

[0064] Specifically, the two first clamping parts 31 are mounted on the base 10 so as to be reciprocatingly movable along the first direction through the first sliding guide pair 32. The first sliding guide pair 32 includes a first linear guide rail and a first slider. The first linear guide rail is fixedly mounted on the bottom surface of the base 10 and extends along the first direction. The first slider is fixedly mounted on the first clamping part 31 and is sleeved on the first linear guide rail through the first slider.

[0065] The cell module clamping device proposed in the present application is provided with a locking mechanism 40. After the two first clamping parts 31 clamp the cell module 50, the two first clamping parts 31 are locked relative to the base 10 through the locking mechanism 40, thereby ensuring that the cell module 50 will not push the two first clamping parts 31 away due to the inertia of the cell module 50 impacting the first clamping mechanism 30 during transportation, thereby greatly improving the stability and safety and reliability of the cell module clamping device in clamping the cell module 50.

[0066] As an embodiment, the locking mechanism 40 includes two sets of locking assemblies 41, each set of locking assemblies 41 corresponds to a first clamping portion 31, and the locking assembly 41 includes a second driving member 410, a first locking portion and a second locking portion. The driving end of the second driving member 410 is connected to the first locking portion, one of the first locking portion and the second locking portion is arranged on the base 10, and the other is arranged on the first clamping portion 31; the second driving member 410 is configured to drive the first locking portion to abut against the second locking portion so that the first clamping portion 31 is locked relative to the base 10; the second driving member 410 is also configured to drive the first locking portion to disengage from the second locking portion to release the lock on the first clamping portion 31.

[0067] It can be seen that by setting two sets of locking assemblies 41, each set of locking assemblies 41 corresponds to a first clamping part 31, the two first clamping parts 31 are respectively locked relative to the base 10, thereby improving the stability and reliability of the locking mechanism 40 in locking the two first clamping parts 31 relative to the base 10; through the cooperation of the second driving member 410, the first locking part and the second locking part, the locking and unlocking of the first clamping part 31 relative to the base 10 are realized, providing a locking assembly 41 with a simple structure and easy implementation.

[0068] See also Figure 1 、 Figure 3 and Figure 4As shown, as an embodiment, the first locking portion includes a lock head 411, and the end of the lock head 411 pointing to the second locking portion has a lock tooth 412, the second locking portion includes a rack 413 extending along the first direction, the fixed end of the second driving member 410 is installed on the base 10, and the rack 413 is fixedly installed on the corresponding first clamping portion 31, the second driving member 410 is configured to drive the lock tooth 412 of the lock head 411 to abut against and engage the rack 413, and the second driving member 410 is also configured to drive the lock The head 411 is away from the rack 413 so that the lock teeth 412 of the lock head 411 are disengaged from the rack 413; alternatively, the fixed end of the second driving member 410 is installed on the corresponding first clamping portion 31, and the rack 413 is fixedly installed on the base 10. The second driving member 410 is configured to drive the lock teeth 412 of the lock head 411 to abut against and engage with the rack 413. The second driving member 410 is also configured to drive the lock head 411 away from the rack 413 so that the lock teeth 412 of the lock head 411 are disengaged from the rack 413.

[0069] As can be seen, the cooperation between the lock teeth 412 and the rack 413 of the lock head 411 achieves reliable locking of the first locking portion and the second locking portion, thereby ensuring reliable locking of the first clamping portion 31 and the base 10. At the same time, two different arrangements of the second drive member 410, the lock head 411, and the rack 413 are provided, which has good applicability. The lock teeth 412 can engage with the teeth at any position of the rack 413, making the battery module clamping device of the present application adaptable to battery modules of various widths and sizes, and can ensure that the locking assembly 41 cooperates with and locks the first clamping mechanism 30.

[0070] As an embodiment, the second driving member 410 is a cylinder, and the first locking part also includes a lifting member 414 and an elastic member 415.

[0073] As an embodiment, the first locking portion also includes a limit block 416 and a guide sleeve 417. The driving end of the second driving member 410 is connected to the limit block 416. The limit block 416 has a receiving space 418 extending along the driving direction of the second driving member 410.

[0074] It can be seen that by providing the limit block 416 and the guide sleeve 417, after the second driving member 410 drives the limit block 416 to descend, since there is a receiving space 418 in the limit block 416, the lifting member 414 will extend downward under the elastic force of the elastic member 415, thereby pressing the lock head 411 against the rack 413; it can also improve the fault tolerance of the locking action. If the lock head 411 is not just stuck on the rack 413, the protrusion 419 of the lifting member 414 can swing in the limit block 416, and then automatically adjust the position of the lock head 411 according to the reaction force of the rack 413, so that the lock head 411 can engage with the rack 413.

The second driving member 410 is configured to drive the positioning pin to be inserted into the corresponding positioning hole so that the two first clamping portions 31 are locked relative to the base 10.

[0077] It can be seen that through the cooperation of the positioning pins and the positioning holes, the two first clamping parts 31 are locked relative to the base 10, which has a simple structure and low cost; at the same time, two different arrangements of the second driving parts 410, positioning pins and positioning holes are provided, which has good applicability; a number of positioning holes are set to enable the locking assembly 41 to be compatible with battery cell modules of different sizes.
