[0043] See also Figures 1 to 12 In this embodiment, a hinged clamping mechanism is provided, comprising a support assembly 1 and a first clamping assembly 2, wherein the first clamping assembly 2 is arranged on the support assembly 1;

[0044] The first clamping component 2 includes a first connecting member 20, a first clamping member 21, a second clamping member 22, a first driving member 23, an elastic member 24 and a transmission member 25. The first clamping component 2 is arranged on the supporting component 1 through the first connecting member 20. The first clamping member 21 and the second clamping member 22 are respectively arranged at the two ends of the first connecting member 20 away from the supporting component 1, and the first clamping member 21 and the second clamping member 22 are slidably connected to the first connecting member 20. The first clamping member 21 and the second clamping member 22 are connected through the elastic member 24. The first driving member 23 is arranged on the first connecting member 20. The first driving member 23 is respectively connected to the first clamping member 21 and the second clamping member 22 through the transmission member 25. The first clamping member 21 and the second clamping member 22 are driven by the first driving member 23 to approach each other to clamp the battery cell assembly.

[0045] In this embodiment, the support assembly 1 is the installation base of the entire hinged clamp, providing a stable installation position for the first clamp assembly 2 and the second clamp assembly 3, and connecting with external components, such as connecting with an external robot, to ensure normal operation in a working environment. The first clamp assembly 2 is used to clamp the battery cell assembly during the stacking process of the battery cell module. Among them, the first connecting member 20 is a connecting member between the first clamp assembly 2 and the support assembly 1, which can install and fix the entire first clamp assembly 2 on the support assembly 1, ensuring that the first clamp assembly 2 is in a suitable position, and it itself is also provided with a slide rail for cooperating with other components such as the first clamp assembly 21. Specifically, as shown in FIG. Figure 2 , Figure 3 As shown, the first connecting member 20 includes mounting plates at both ends, and the mounting plates at both ends are connected by four pillars. The mounting plate at the upper end is used to connect with the support assembly 1, and the mounting plate at the lower end is used to connect with the transmission member 25. The space between the two mounting plates is used to install the first driving member 23, and the mounting plate at the lower end is provided with an avoidance hole for avoiding the transmission member 25. The first clamping member 21 and the second clamping member 22 directly contact the battery core assembly and realize the clamping function, such as Figure 2 , Figure 3 and Fig.12As shown, the clamping surfaces of the first clamping member 21 and the second clamping member 22 are arranged opposite to each other to fit the two sides of the battery cell assembly, thereby realizing the positioning, fixing and transportation operations of the battery cell assembly. The first driving member 23 is the power source of the entire first clamping assembly 2. When the clamping mechanism is working, it receives an external control signal or energy input (such as electrical energy, etc.), and then drives the transmission member 25 to move, and finally drives the first clamping member 21 and the second clamping member 22 to approach each other, prompting the clamping mechanism to complete the clamping action. The elastic member 24 is used for resetting and buffering. On the one hand, when the first clamping member 21 and the second clamping member 22 are driven by the first driving member 23 to approach each other and complete the clamping of the battery cell assembly, if the battery cell assembly needs to be released, the elastic member 24 can rely on its own elastic deformation recovery force to assist the two clamping members to return to the initial relative position, and play a resetting role; on the other hand, during the clamping process, if there are slight differences in the size of the battery cell assembly or a certain external force impact, the elastic member 24 can buffer these changes through its own elastic deformation, avoid rigid contact from causing damage to the battery cell assembly or the clamping member, and ensure that the clamping process is more stable and reliable. The transmission member 25 is used to connect the first driving member 23 with the first clamping member 21 and the second clamping member 22 to transmit the power of the first driving member 23. It can be understood that the first driving member 23 can be a motor or a cylinder. The following sentences involving the driving member can be a motor or a cylinder, and will not be repeated in the following text.

[0046] In the above embodiment, the first driving member 23 drives the first clamping member 21 and the second clamping member 22 to compress the elastic member 24, so that the first clamping member 21 and the second clamping member 22 can be close to each other to clamp the battery cell assembly. When the battery cell assembly needs to be released, the elastic member 24 pops the first clamping member 21 and the second clamping member 22 apart, so that the first clamping member 21 and the second clamping member 22 can be moved away from each other to release the battery cell assembly. By arranging a plurality of first clamping assemblies 2 on the supporting assembly 1, the stacking of battery cell assemblies of a plurality of pre-stacking channels can be completed at the same time, thereby reducing the stacking time of the module stacking process and improving production efficiency.

[0047] See also Figures 1 to 12In one embodiment, the transmission member 25 includes a sliding portion 250 and a hinge portion 251; the sliding portion 250 includes a first slide plate 2501 and a second slide plate 2500, and the first slide plate 2501 and the second slide plate 2500 are both provided with a first slider 2502, and the first connecting member 20 includes a first slide rail 200, and the first slide plate 2501 and the second slide plate 2500 are respectively provided at two ends of the first slide rail 200, and the first slide plate 2501 and the second slide plate 2500 are connected to the first slide rail 200. The connecting member 20 is connected to the first slide rail 200 through the first slider 2502; the hinge part 251 includes a first hinge block 2510, a second hinge block 2511 and a third hinge block 2512; the first hinge block 2510 is hinged to the third hinge block 2512 through the second hinge block 2511, the first hinge block 2510 and the first slide plate 2501 are hinged, and the second hinge block 2511 and the second slide plate 2500 are hinged; the first slide plate 2501 is connected to the first driving member 23.

[0048] In this embodiment, the transmission member 25 plays a key role in power transmission and motion conversion in the entire first clamping assembly 2. It can transmit the power output by the first driving member 23 to the first clamping member 21 and the second clamping member 22 in a hinge motion. Specifically, the sliding part 250 is used for motion bearing and guidance. The first slide plate 2501 and the second slide plate 2500 are key components for receiving the power from the first driving member 23 and cooperating with the hinge part 251. The first slide plate 2502 provided on the first slide plate 2502 is connected to the first slide rail 200 of the first connecting member 20, so that the first slide plate 2501 and the second slide plate 2500 can slide relative to each other along the first slide rail 200, thereby ensuring the accuracy and stability of the motion during the power transmission process, avoiding unnecessary deviation or shaking, and laying a foundation for the subsequent accurate movement of the clamping member. The first slider 2502 can slide smoothly in the first slide rail 200. On the one hand, the first slide plate 2501 and the second slide plate 2500 can change their positions relative to the first connecting member 20, and realize the coordinated movement with the hinge part 251 and other parts; on the other hand, the slide rail plays a guiding and limiting role for the slider, constraining it to move only along the direction of the slide rail, thereby ensuring the certainty of the motion trajectory during the entire transmission process, so that the power transmission can be carried out according to the preset path, and then accurately drive the relevant clamping parts to complete the clamping action. The hinge part 251 is used for motion conversion and transmission, wherein one end of the first hinge block 2510 is hinged to the first slide plate 2501, so that it can receive the power and corresponding motion trend transmitted from the first slide plate 2501 and generated by the first driving member 23, and then transmit this power and motion state through the hinge relationship with the second hinge block 2511, so as to realize the preliminary conversion and transmission of the motion direction and force, and play a connecting role in the entire hinged transmission chain; the second hinge block 2511 is in a key position of the middle connection, on the one hand, it is connected with the first drive member 23, and on the other hand, it is connected with the second drive member 23, and on the other ... The first hinge block 2510 is hinged to receive power and motion from the first hinge block 2510, and on the other hand, it is hinged to the third hinge block 2512 to continue transmitting power and motion to the third hinge block 2512, and it is hinged to the fixed block 2513. The fixed block 2513 can ensure that the first hinge block 2510 rotates only within a limited range, providing certain support and constraints for the movement of the entire hinge part 251, ensuring the smoothness of motion transmission and the stability of the entire hinge structure, so that the motion can be reasonably converted and transmitted between the hinge blocks according to design requirements. The third hinge block 2512 serves as the end link of the hinge part 251 (relative to the above connection sequence). It is hinged to the second hinge block 2511, receives the transmitted power and movement, and finally transmits the power to the clamping parts through its own connection with the first clamping part 21 or the second clamping part 22, driving them to perform a clamping action close to each other, thereby converting the movement of the hinge part 251 into an effective movement of the clamping parts, and completing the clamping function of the battery cell assembly.

[0049] In the above embodiment, the entire hinge part 251 forms a chain structure that can flexibly change the direction of movement and adapt to the relative position changes of different components through the hinged connection between the hinge blocks. This structure allows the linear motion from the first driving member 23 (transmitted by the sliding motion of the first slide plate 2501, etc.) to be converted into a relative motion that can drive the first clamping member 21 and the second clamping member 22 to approach each other at a specific angle and in a certain manner, meeting the requirements of the clamping mechanism for movement flexibility and accuracy when clamping the battery cell assembly, ensuring that the entire transmission process can be carried out smoothly under a relatively complex spatial layout, and realizing effective driving of the clamping action.

[0050] See also Figures 1 to 12 In one embodiment, the hinge portion 251 also includes a fixed block 2513, one end of the fixed block 2513 is connected to the first connecting member 20, and the other end is hinged to the second hinge block 2511, and the position where the fixed block 2513 is hinged to the second hinge block 2511 is the middle part of the second hinge block 2511.

[0051] In this embodiment, one end of the fixed block 2513 is fixedly connected to the first connecting member 20 by bolts, and the other end is hinged to the middle part of the second hinge block 2511. This not only ensures that the second hinge block 2511 can be fixed at the position of the fixed block 2513 without causing unreasonable movements such as stringing, excessive swinging, and offset, but also ensures that the second hinge block 2511 can rotate around the middle part to ensure effective transmission of power.

[0052] Please continue reading Figures 1 to 12 In one embodiment, the first clamping member 21 and the second clamping member 22 both include a clamping plate 210 and a clamping block 211 , the clamping surface of the first clamping member 21 and the clamping surface of the second clamping member 22 are arranged opposite to each other, and the clamping block 211 is arranged on the clamping surface of the clamping plate 210 .

[0053] In this embodiment, the clamping plate 210, as the main structural part of the first clamping member 21 and the second clamping member 22, provides a stable support frame for the entire clamping member. It undertakes the important tasks of connecting other auxiliary components and bearing external forces. During the operation of the clamping mechanism, it must be able to withstand the driving force transmitted by the first driving member 23, the reaction force of the battery cell assembly and other forces, to ensure that the overall structure of the clamping member will not be deformed or damaged, and to maintain the stability and reliability of the entire clamping action. The clamping plate 210 is slidably connected to the first connecting member 20, and receives the power from the first driving member 23 through the transmission member 25, thereby driving the entire clamping member to move. It can accurately transmit the motion state generated by this power to the clamping block 211 set on its clamping surface, ensuring that the clamping block 211 can move closer or farther from each other as required along with the clamping plate 210, to achieve the clamping and loosening of the battery cell assembly, and is the key link of the entire power transmission chain in the clamping member part. The clamping block 211 is disposed on the clamping surface of the clamping plate 210 and is the part that directly contacts the battery cell assembly. Its material and surface characteristics can be designed according to the characteristics of the battery cell assembly, and this application does not make specific restrictions. Figure 4 , Figure 5 As shown, the surface of the clamping block 211 is provided with a plurality of grooves, the concave parts within the grooves are used to clamp the insulating spacers, and the protruding parts between the grooves are provided with rough surfaces for clamping the battery cells.

[0054] Furthermore, the clamping block 211 is made of insulating material, which can prevent electrical conduction when in contact with the battery cell.

[0055] Please continue reading Figures 1 to 12 In one embodiment, second driving members 212 are disposed opposite to the clamping ends of the first clamping member 21 and the second clamping member 22 .

[0056] In this embodiment, the second driving member 212 is disposed at the clamping ends of the first clamping member 21 and the second clamping member 22, which can prevent the battery cell from falling during the movement. It can be understood that the driving part of the second driving member 212 can be extended and retracted. When the two second driving members 212 are in the extended state, they can be used to support the battery cell assembly from the bottom of the first clamping member 21 and the second clamping member 22, thereby preventing the battery cell from falling due to the failure to clamp the battery cell assembly.

[0057] Please continue reading Figures 1 to 12In one embodiment, the hinged clamping mechanism also includes a second clamping component 3, and the second clamping component 3 and the first clamping component 2 are arranged correspondingly on the support component 1; the second clamping component 3 includes a second connecting member 30, a third clamping member 31, a fourth clamping member 32, and a third driving member 33; the third driving member 33 is connected to the second connecting member 30, and the third clamping member 31 and the fourth clamping member 32 are both slidably connected to the second connecting member 30, and the third clamping member 31 and the fourth clamping member 32 are both movably connected to the third driving member 33, and the third clamping member 31 and the fourth clamping member 32 can approach or move away from each other under the drive of the third driving member 33.

[0058] In this embodiment, the second clamping assembly 3 is used to clamp the end plate of the battery cell assembly. The second clamping assembly 3 is arranged on the support assembly 1 in correspondence with the first clamping assembly 2, which can ensure that the corresponding number of end plates are moved to the battery cell stacking process at the same time, and assembled with the battery cells and insulating partitions to form a battery cell assembly. On the one hand, the second connecting member 30 establishes a connection with the support assembly 1, so that the entire second clamping assembly 3 can be firmly installed on the support assembly 1, ensuring the accuracy and stability of its position; on the other hand, it provides a support for the installation and sliding of the third clamping member 31 and the fourth clamping member 32, carrying these two clamping members so that they can slide on their surface in a predetermined manner to achieve the clamping function. The third clamping member 31 and the fourth clamping member 32 are the parts of the second clamping assembly 3 that directly contact the clamped object and implement the clamping action. Similar to the clamping members in the first clamping assembly 2, the opposing surfaces of the two are used to fit the corresponding parts of the clamped object. By moving closer or farther away from each other under the drive of the third driving member 33, the clamping or loosening operation of the object is realized, thereby ensuring that the object is in a stable fixed state or can be released smoothly under the action of the clamping mechanism, and plays a core execution role in the entire clamping process. The third driving member 33 is the power source for driving the third clamping member 31 and the fourth clamping member 32 to move. It receives external control instructions or energy input (such as electrical energy, etc.), and then converts it into mechanical energy, driving the third clamping member 31 and the fourth clamping member 32 that are movably connected thereto to move closer or farther away from each other.

[0059] In the above embodiment, the third driving member 33 is connected to the second connecting member 30, which ensures that the driving member itself has a stable installation foundation so that the power output function can be better exerted. The third clamping member 31 and the fourth clamping member 32 are both slidably connected to the second connecting member 30. Such a connection method limits their movement paths, so that they can only slide along the direction limited by the second connecting member 30, ensuring the accuracy and stability of the movement. At the same time, they are both movably connected to the third driving member 33. Through this movably connected method, the third driving member 33 can effectively transmit the power generated by itself to the third clamping member 31 and the fourth clamping member 32, so that the two can move closer or farther from each other as required, thereby achieving effective clamping of the clamped object, thereby cooperating with the first clamping assembly 2 to firmly fix the object from multiple directions and ensure the clamping effect of the entire clamping mechanism.

[0060] For details, please refer to Fig. 9 The driving ends of the third driving member 33 are respectively movably connected to the third slider 311 to drive the third slider 311 to move along the third slide rail 310 .

[0061] Please continue reading Figures 1 to 12 In one embodiment, the second connecting member 30 is provided with a second slide rail 35, the supporting assembly 1 is provided with a fourth driving member 11 and a supporting plate 10, the fourth driving member 11 is fixedly connected to the supporting plate 10 through a second slider, the second slider is slidably connected to the second slide rail 35, the fourth driving member 11 is movably connected to the second connecting member 30, and the second connecting member 30 moves relative to the supporting plate 10 under the drive of the fourth driving member 11.

[0062] In this embodiment, the second slide rail 35 is arranged on the second connecting member 30, providing a clear guide path for the subsequent relative movement of the entire second clamping assembly 3. It limits the second connecting member 30 and the third clamping member 31, the fourth clamping member 32 and other components installed thereon to move only along the direction set by the slide rail, avoiding random deviation or swinging during the movement, and ensuring the accuracy and stability of the movement. As a power source for driving the second connecting member 30 to move, the fourth driving member 11 receives the corresponding control signal or energy input (such as electrical energy, etc.), and converts it into mechanical energy, which acts on the second connecting member 30 movably connected thereto, so that it produces relative movement. The support plate 10 is a part of the support assembly 1, which provides a stable support platform for the structure of the entire clamping mechanism. It carries the fourth driving member 11 and the second connecting member 30 connected thereto through the second slider, etc., ensuring that these components have a stable installation foundation during the working process. Even when subjected to various forces (such as the driving force generated by the driving member, the reaction force when the clamping claw clamps the battery cell assembly, etc.), the stability of the entire mechanism structure can still be maintained, so that each component can work together normally, and the reliability and durability of the clamping mechanism as a whole are guaranteed. The second slider plays a key role in connecting the fourth driving member 11 with the second slide rail 35. On the one hand, it is fixedly connected to the fourth driving member 11, so that the power output by the fourth driving member 11 can be transmitted through it; on the other hand, it forms a sliding connection with the second slide rail 35, so that while the power is transmitted, it can drive the second connecting member 30 to slide relatively along the second slide rail 35, realizing the function of converting the power of the fourth driving member 11 into the linear movement of the second connecting member 30, and is an indispensable intermediate link in the entire power transmission and motion realization chain, ensuring the effective conversion and transmission between power and motion.

[0063] In the above embodiment, it can be understood that the first clamping assembly 2 and the second clamping assembly 3 are both arranged on the support assembly 1, and when they are used to clamp the battery cell assembly and the end plate at the same time, interference is likely to occur. When the first clamping assembly 2 clamps the battery cell assembly, it is easy to cause the second clamping assembly 3 to be unable to clamp the end plate. Therefore, the second slide rail 35, the second slider and the fourth drive member 11 are provided in the present application to avoid the above problem. After the first clamping assembly 2 clamps the battery cell assembly, the second clamping assembly 3 can be extended and retracted under the drive of the fourth drive member 11 to extend the clamping stroke, thereby avoiding interference.

[0064] See also Figures 1 to 12 In one embodiment, the second clamping assembly 3 further includes a buffer member 34 , which is disposed on the second connecting member 30 . The buffer members 34 are respectively distributed on both sides of the support plate 10 . The buffer members 34 can contact the support plate 10 when driven by the fourth driving member 11 .

[0065] In this embodiment, the buffer 34 is made of a material with elastic deformation ability, such as rubber, spring, etc., so that it can absorb and buffer energy through its own elastic deformation when subjected to force. It can be understood that when the fourth driving member 11 drives the second connecting member 30 to move relative to the support plate 10, impact force and vibration are easily generated due to the inertia of mechanical movement, the change of driving force or the possible matching gap between components. During this process, when the buffer 34 contacts the support plate 10, it can absorb these impact forces by relying on its own elastic deformation, convert the instantaneous and large impact force into its own elastic potential energy for storage, and gradually release it, thereby effectively reducing the impact of the entire mechanism during the movement process, avoiding damage to various components due to excessive impact force, such as preventing the second connecting member 30, the support plate 10 and other components connected thereto from deformation, wear and even breakage, etc., extending the service life of various components of the clamping mechanism, and ensuring the stability of the mechanism operation. The buffer 34 is distributed on both sides of the support plate 10, and can also play a certain limiting role. When the second connecting member 30 moves to a certain extent under the drive of the fourth driving member 11, the buffer member 34 will first contact the support plate 10 to limit the second connecting member 30 from continuing to move excessively, prevent it from exceeding the normal range of motion and colliding, squeezing and other abnormal situations with other components, avoid causing unnecessary mechanical failures and safety hazards, ensure that the movement of the second connecting member 30 is always within a reasonable and controllable range, and maintain the normal working order of the entire clamping mechanism.

[0066] Please continue to refer to 1 to Fig.12 In one embodiment, stabilizing blocks 312 are disposed on the third clamping member 31 and the fourth clamping member 32 relative to each other.

[0067] It should be noted that the specific shape of the stabilizing block 312 is not specifically required in this embodiment, and it needs to be set according to the structural characteristics of the specific end plate in the actual application process. In this embodiment, when clamping objects such as battery core components, the stabilizing block 312 can increase the contact area and contact points between the third clamping member 31 and the fourth clamping member 32 and the clamped object. Since the thickness of the end plate is much smaller than the length of the end plate, and in the actual process, the thickness of the clamping end plate is often clamped, the contact surface is relatively small, and there is no other contact part in the length direction of the end plate, which is easy to cause the end plate to fall during the transfer process. The object is supported and fixed from multiple positions, thereby enhancing the stability of the clamping and preventing the object from shaking or shifting during the clamping process.

[0068] Please continue reading Figures 1 to 12 In one embodiment, the support assembly 1 further includes a connector 12 , and the connector 12 is disposed on the support plate 10 .

[0069] In this embodiment, the connector 12 is used to connect to the robot arm. The shape and size of the connector 12 are based on the structural design of the robot arm, and the design purpose is to adapt to the corresponding connection part on the robot arm, so as to achieve a reliable and stable mechanical connection. Specifically, flange connection, snap connection or pin connection can be used to ensure that the clamping mechanism can be firmly installed at the end effector position of the robot arm, avoid the clamping mechanism from loosening or falling off during various rapid and complex movements of the robot arm, and ensure the integrity and synchronization of the two during the movement.

[0070] The process of clamping the battery cell assembly by the hinged clamping mechanism provided by the present invention is:

[0071] The mechanical arm drives the chain clamping mechanism to grab the battery cell assembly, and the state of the battery cell assembly is that the battery cell and the insulating partition are alternately abutted, and the end plate is not in contact with the battery cell and the insulating partition; when clamping the battery cell and the insulating partition, the first driving member 23 drives the first slide plate 2501 to move in the direction of the second slide plate 2500 under the action of the first slide rail 200 and the first slider 2502; at the same time, the first slide plate 2501 transmits the driving force to the second slide plate 2500 along the path of the first hinge block 2510, the second hinge block 2511 and the third hinge block 2512, and the second slide plate 2500 moves in the direction of the first slide plate 2501 under the action of the second slider and the first slide rail 200, and the elastic member 24 is compressed in the process of the two moving toward each other to clamp the battery cell and the insulating partition; the second driving member 212 drives the second slider to move along the second slide rail 3 5 Slide until the third clamping member 31 and the fourth clamping member 32 contact the end plate, and the stabilizing block 312 passes through the end plate; the third driving member 33 drives the third slider 311 to slide along the third slide rail 310 to clamp the end plate, and after the clamping is stable; the second driving member 212 drives the second slider to slide and reset along the second slide rail 35; the mechanical arm drives the chain clamping mechanism to move the battery cell assembly to the preset position, the first driving member 23 contracts, and under the reset action of the elastic member 24, the first slide plate 2501 and the second slide plate 2500 move in the direction to release the battery cell and the insulating partition; at the same time, the second driving member 212 drives the second slider to slide along the second slide rail 35 to the end plate placement position, and the third driving member 33 drives the third slider 311 to slide along the third slide rail 310 to release the end plate, and finally the components in the chain clamping mechanism are reset, and the mechanical arm is reset.

[0072] In summary, a hinged clamping mechanism of an embodiment of the present application includes a support component 1 and a first clamping component 2, wherein the first clamping component 2 is arranged on the support component 1; the first clamping component 2 includes a first connecting member 20, a first clamping member 21, a second clamping member 22, a first driving member 23, an elastic member 24 and a transmission member 25, the first clamping component 2 is arranged on the support component 1 through the first connecting member 20, the first clamping member 21 and the second clamping member 22 are respectively arranged at the two ends of the first connecting member 20 away from the support component 1, and the first clamping member 21 and the second clamping member 22 are slidably connected to the first connecting member 20, the first clamping member 21 and the second clamping member 22 are connected through the elastic member 24, the first driving member 23 is arranged on the first connecting member 20, and the first driving member 23 is respectively connected to the first clamping member 21 and the second clamping member 22 through the transmission member 25, and the first clamping member 21 and the second clamping member 22 are driven by the first driving member 23 to approach each other to clamp the battery cell assembly. In the pre-stacking of the battery cell assemblies, the technical solution drives the first clamping member 21 and the second clamping member 22 to compress the elastic member 24 through the first driving member 23, so that the first clamping member 21 and the second clamping member 22 can be close to each other to clamp the battery cell assembly. When the battery cell assembly needs to be released, the first clamping member 21 and the second clamping member 22 are bounced apart by the elastic member 24, so that the first clamping member 21 and the second clamping member 22 can be moved away from each other to release the battery cell assembly. By arranging a plurality of first clamping assemblies 2 on the supporting assembly 1, the stacking of battery cell assemblies of a plurality of pre-stacking channels can be completed at the same time, thereby reducing the stacking time of the module stacking process and improving production efficiency.
