[0026] In one embodiment of this utility model, such as Figures 1-3 As shown, a lithium battery gripper 24 is provided, including: a mounting base 10 for connecting to an external robotic arm; The symmetrically arranged clamping assembly 20 includes a first clamping member 21 and a second clamping member 22 for clamping lithium batteries; A buffer adjustment mechanism 30 is disposed between the mounting base 10 and the clamping assembly 20, and is used to provide buffering and adjust the clamping distance; The identification system 40 is used to detect the shape and position of the lithium battery and control the action of the clamping assembly 20.

[0027] Specifically, the lithium battery gripper 24 involved in this utility model... The buffer adjustment mechanism 30 provides a flexible buffer effect between the mounting base 10 and the clamping assembly 20, which can effectively absorb the impact force that may be generated during transportation, thereby preventing the lithium battery from suffering surface damage or internal structural damage due to accidental collision. In addition, the gripper 24 is also equipped with an identification system 40, which can detect the shape, size and position information of the battery in real time, and can be linked with the action of the gripping component 20. Combined with the gripping distance adjustment function of the buffer adjustment mechanism 30, the gripper 24 can flexibly and adaptively grip various lithium batteries such as square, cylindrical, soft pack and blade-shaped. Through the synergy of proactive identification and buffer protection, the need for manual intervention is significantly reduced, and stable operation in processes such as handling, sorting, and welding is ensured, thereby greatly improving the safety and efficiency of the production line.

[0028] In another embodiment of this utility model, such as Figures 1-3 As shown, the buffer adjustment mechanism 30 includes: The variable pitch drive device 31 is used to drive the first clamping member 21 and the second clamping member 22 to move relative to each other. A horizontal buffer component 32 is disposed on the moving path of the clamping component 20 and is used for horizontal buffering. A vertical buffer assembly 33 is disposed between the mounting base 10 and the clamping assembly 20 for vertical buffering. Specifically, by splitting the buffer adjustment mechanism 30 into horizontal and vertical buffer assemblies, and combining it with the variable-pitch drive device 31, multi-dimensional buffering protection and precise spacing adjustment for lithium batteries during handling can be achieved. In the horizontal direction, it effectively prevents displacement of the lithium battery due to lateral impact; in the vertical direction, it prevents collision damage caused by height differences. Combined with the variable-pitch function, it significantly improves the compatibility and clamping stability of the grippers 24 for lithium batteries of different sizes.

[0029] In another embodiment of this utility model, such as Figures 1-3 As shown, the variable pitch drive device 31 is a bidirectional cylinder, and its output end is connected to the clamping assembly 20 via a fixing plate. Specifically, using a bidirectional cylinder as the variable pitch drive device 31 has the characteristics of fast response speed and stable driving force. Connecting the clamping assembly 20 via the fixing plate ensures the high efficiency and reliability of power transmission, enabling rapid and precise control of the relative movement of the first clamping member 21 and the second clamping member 22, realizing rapid adjustment of the lithium battery clamping distance, meeting the gripping requirements of lithium batteries of different specifications, and improving the working efficiency of the production line.

[0030] In another embodiment of this utility model, such as Figures 1-3As shown, the horizontal buffer assembly 32 includes a side positioning plate 321, a limiting plate 322, and a buffer. The side positioning plate 321 has a U-shaped groove 323, and both ends of the limiting plate 322 extend into the U-shaped groove 323 and cooperate with the buffer. Specifically, the side positioning plate 321, the limiting plate 322, and the buffer of the horizontal buffer assembly 32 are designed to form a stable horizontal buffer structure. The cooperation between the U-shaped groove 323 and the limiting plate 322 restricts the horizontal movement range of the clamping assembly 20. When a lateral impact occurs, the buffer can quickly absorb the impact force, preventing the lithium battery from violently shaking or colliding in the horizontal direction, effectively protecting the side structure of the lithium battery, and improving the safety during lithium battery handling.

[0031] In another embodiment of this utility model, such as Figures 1-3 As shown, the vertical buffer assembly 33 includes an elastic element, a guide rod 331, and a linear bearing 332. The elastic element is disposed between the mounting base 10 and the clamping assembly 20, and the guide rod 331 passes through the linear bearing 332 to guide the vertical buffering movement. Specifically, the vertical buffer assembly 33 absorbs the vertical impact force through the elastic element, and with the guiding effect of the guide rod 331 and the linear bearing 332, the vertical buffering movement of the clamping assembly 20 is made more stable and precise. When encountering vertical vibration or height changes during handling, the elastic element can effectively buffer the impact, preventing damage to the lithium battery due to vertical impact. At the same time, the guide rod 331 and the linear bearing 332 ensure the stability of the buffering movement and improve the overall working reliability of the gripper 24.

[0032] In another embodiment of this utility model, such as Figures 1-3 As shown, the identification system 40 includes: Visual sensors are used to identify the shape, size, and location of lithium batteries; The controller, electrically connected to the vision sensor and the buffer adjustment mechanism 30, controls the movement of the clamping assembly 20 based on the recognition results. Specifically, the recognition system 40 acquires the shape, size, and position information of the lithium battery in real time through the vision sensor. The controller precisely controls the movements of the buffer adjustment mechanism 30 and the clamping assembly 20 based on this information, enabling the gripper 24 to intelligently grasp the lithium battery. This system can automatically adapt to lithium batteries of different shapes without requiring manual parameter adjustments, greatly reducing human intervention, improving the automation and efficiency of production, and also reducing the risk of lithium battery damage due to human error.

[0033] In another embodiment of this utility model, such as Figures 1-3 As shown, the first clamping assembly 20 and the second clamping assembly 20 have the same structure and both include: Clamping cylinder 23 is fixed to the output end of buffer adjustment mechanism 30; The gripper 24 is connected to the output end of the clamping cylinder 23 and is used to clamp the lithium battery. A buffer pad 25 is disposed on the clamping surface of the gripper 24. Specifically, the clamping assembly 20 uses a clamping cylinder 23 to drive the gripper 24, which can provide a stable and adjustable clamping force to accommodate lithium batteries of different weights and sizes. The buffer pad 25 forms a buffer layer between the gripper 24 and the lithium battery, avoiding direct rigid contact between the gripper 24 and the lithium battery surface, effectively preventing the lithium battery from being pinched or scratched during clamping, further enhancing the protection of the lithium battery and improving the product qualification rate.

[0034] In another embodiment of this utility model, such as Figures 1-3 As shown, the gripper 24 is Z-shaped and stepped, with a detachable gripper pad at its end. The gripper pad is made of an elastic material. Specifically, the Z-shaped stepped gripper design allows for better conformation to the surface contours of lithium batteries of different shapes, increasing clamping stability and reliability. The detachable elastic gripper pad facilitates replacement according to different specifications and surface characteristics of the lithium battery, improving the versatility of the gripper 24. Furthermore, the elastic material further buffers the clamping force, preventing damage to the lithium battery surface and extending the service life of the gripper 24.

[0035] In another embodiment of this utility model, such as Figures 1-3 As shown, the system also includes an anti-detachment structure, which comprises an elastic latch 50 disposed on the gripper 24. The elastic latch 50 engages with the surface of the lithium battery when it is gripped. Specifically, the elastic latch 50 of the anti-detachment structure is designed to engage with the surface of the lithium battery after the gripper 24 has gripped it, providing additional security for the lithium battery. Even when encountering vibrations or tilting during handling, the elastic latch 50 effectively prevents the lithium battery from falling off the gripper 24, greatly improving the safety during lithium battery handling and avoiding equipment damage or production accidents caused by the lithium battery falling off.

[0036] In another embodiment of this utility model, such as Figures 1-3 As shown, it also includes a collision detection alarm device, which comprises: The optoelectronic components are fixed on the mounting base 10; The sensing fixture, fixed to the clamping assembly 20, works in conjunction with the photoelectric component to detect collisions and trigger an alarm. Specifically, the collision detection alarm device, through the cooperation of the photoelectric component and the sensing fixture, can monitor in real time whether the gripper 24 collides during operation. Once a collision is detected, an alarm is immediately triggered, reminding the operator to handle the situation promptly, avoiding damage to the lithium battery or equipment malfunction due to the collision. It also helps to quickly locate and troubleshoot problems, improving the safety and fault handling efficiency of the production line.

[0037] In another embodiment of this utility model, such as Figures 1-3 As shown, the mounting base 10 is equipped with an angle adjustment joint for adjusting the overall angle of the clamping assembly 20. Specifically, the angle adjustment joint allows the clamping assembly 20 to adjust its overall angle according to actual working needs, increasing the flexibility of the gripper 24 in spatial operation. Whether in complex production line layouts or in processes requiring the handling and installation of lithium batteries at specific angles, it can easily adapt, expanding the application scenarios of the gripper 24 and improving the equipment's versatility and production efficiency.

[0038] In another embodiment of this utility model, such as Figures 1-3 As shown, the gripping surface of the jaws 24 is provided with anti-slip textures and a cavity for accommodating the lithium battery, with a rubber pad placed inside the cavity. Specifically, the anti-slip textures on the gripping surface of the jaws 24 increase the friction with the surface of the lithium battery, preventing the lithium battery from slipping during gripping; the cavity for accommodating the lithium battery, together with the rubber pad, can better secure the lithium battery, making the contact between the jaws 24 and the lithium battery tighter and more stable. At the same time, the rubber pad acts as a buffer and protector, preventing damage to the surface of the lithium battery due to excessive gripping force, thus ensuring the stability and safety of the lithium battery during transportation.

[0039] In another embodiment of this utility model, such as Figures 1-3 As shown, the elastic element of the vertical buffer assembly 33 is a buffer spring, which is disposed in the groove between the mounting plate and the buffer plate. Specifically, using a buffer spring as the elastic element of the vertical buffer assembly 33 results in a simple structure and low cost, while also providing good elasticity and buffering performance. Distributing the buffer spring in the groove between the mounting plate and the buffer plate effectively fixes the spring's position, ensuring its stability during compression and rebound, thereby reliably absorbing vertical impact forces and providing stable vertical buffer protection for the lithium battery, thus improving the overall performance and reliability of the gripper 24.
