[0002] In the field of modern industrial manufacturing, with the wide expansion of the application of lithium batteries, the demand for clamping mechanisms in the production and testing processes is also increasing day by day. Traditional lithium battery clamping mechanisms are usually designed with clamping jaws of fixed spacing. Due to the fixed spacing of the clamping jaws, when facing the actual production situation, there may be inconsistent spacing in the product loading and unloading production line or the tray. The current battery clamping mechanism cannot meet the production requirements, and the equipment compatibility and adaptability are poor, resulting in limited efficiency in the conveying and positioning of materials. In addition, to meet the actual production requirements, manufacturers may need to purchase multiple sets of clamping mechanisms for different production lines or trays, which not only increases the equipment cost, but also requires a large amount of manpower and material resources when changing product specifications, reducing the production efficiency.

[0028] Refer to Figure 1 , this embodiment discloses a lithium battery clamping device, including a robotic arm device 1, a jaw pitch-changing device 2, and a battery clamping device 3. The robotic arm device 1 is connected to the battery clamping device 3 through the jaw pitch-changing device 2.

[0029] Refer to Figure 2, the buffer assembly 11 includes a robotic arm 111, a mounting plate 112, an elastic member 113, a linear bearing 114, a buffer plate 115, a guide rod 116, and a bearing gasket 117. The robotic arm 111 and the mounting plate 112 are bolt - fixed through an intermediate connecting plate, providing power and direction control for the entire lithium - battery clamping device. The mounting plate 112 is connected to the buffer plate 115 through elastic members 113 along the four corner - end directions. When there is a phenomenon that the robotic arm 111 presses the battery downward, the elastic members 113 can serve as a buffer area to protect the robotic arm 111 from stress damage in a timely manner. In this embodiment, the elastic member 115 is a buffer spring. Four guide rods 116 are bolt - fixed at the four corner - ends of the mounting plate 112, and at the corresponding positions, four linear bearings 114 are bolt - fixed at the four corner - ends of the buffer plate 115 and the guide rods 116 are sleeved therein. The bearing gasket 117 is fixed at the bottom of the linear bearing 114.

[0030] Specifically, four linear bearings 114 are bolt - fixed at the four corner - ends of the buffer plate 115. Due to the gravity of tooling such as the buffer plate 115, the linear bearings 114 are always located at the position of the bottom bearing gasket 117. Through the guiding action of the linear bearings 114 and their cooperation with the guide rods 116, it is ensured that during the process of the robotic arm 111 placing the battery downward, the entire lithium - battery clamping device remains horizontal and its position does not tilt, avoiding production accidents such as battery extrusion.

[0031] The safety alarm assembly 12 includes an optoelectronic component 121 and an induction tooling 122. The optoelectronic component 121 is fixed on the mounting plate 112, and the induction tooling 122 is fixed on the buffer plate 115. Specifically, in this embodiment, the optoelectronic induction end of the optoelectronic component 121 is U - shaped, and the induction tooling 122 is L - shaped. The horizontal section of the induction tooling 122 is fixed on the buffer plate 115, and the vertical section is arranged towards the optoelectronic induction end of the optoelectronic component 121, so that the vertical section of the induction tooling 122 can penetrate the optoelectronic induction end of the optoelectronic component 121.

[0032] Specifically, when the robotic arm 111 normally places the battery, the induction tooling 122 and the optoelectronic component 121 maintain a certain distance and do not trigger a signal. However, when the robotic arm 111 presses the battery downward, the buffer plate 115 receives a vertically upward stress, presses the elastic member 113 upward, and displaces upward along the guide rod 116 through the linear bearing 114, driving the induction tooling 122 to move synchronously until it passes through the optoelectronic induction end of the optoelectronic component 121, thereby triggering a signal and giving an alarm, and urgently braking the robotic arm 111 to avoid causing greater production accidents.

[0033] Refer to Figure 3 and Figure 4, the gripper pitch-changing device 2 includes a pitch-changing cylinder 21, side positioning plates 22, a limit plate 23, and a buffer 24. The fixed end of the pitch-changing cylinder 21 is connected to a buffer plate 115. In this embodiment, the pitch-changing cylinder 21 is a two-way cylinder. The two output ends of the pitch-changing cylinder 21 are respectively connected to the limit plate 23. The bottom of the limit plate 23 is connected to the battery clamping device 3, and the limit plate 23 is driven by the pitch-changing cylinder 21 to displace in the horizontal direction; on both sides of the pitch-changing cylinder 21, there are side positioning plates 22. Each side positioning plate 23 is provided with symmetric U-shaped grooves. On the side positioning plate 23 between the two U-shaped grooves, there are bolt holes for installing the buffer 24. In this embodiment, both ends of the limit plate 23 have protruding parts and extend into the U-shaped grooves on the side positioning plate 23. Specifically, the allowable displacement distance of the limit plate 23 is the difference between the horizontal distance of the U-shaped groove and the horizontal distance of the buffer 24 outside the bolt hole. By adjusting the bolts on the buffer 24, the displacement stroke of the two limit plates 23 in the horizontal direction can be controlled, realizing the adjustable and controllable displacement of the limit plate 23 in the horizontal direction.

[0034] Refer to Figure 5 , the battery clamping device 3 includes a connecting plate 31, a clamping cylinder 32, and grippers 33. The clamping cylinder 32 is connected to the limit plate 23 through the connecting plate 31. In this embodiment, the clamping cylinder 32 is a two-way cylinder. The two output ends of the clamping cylinder 32 are respectively connected with grippers 33. Specifically, the two clamping cylinders 32 maintain a certain distance, and the distance between the clamping cylinders 32 is adjusted by the gripper pitch-changing device 2. At the ends of the clamping cylinder 32, two grippers 33 are respectively fixed by bolts and displace synchronously with the clamping cylinder 32 to realize the clamping action of the battery.

[0035] Furthermore, the grippers 33 are in a Z-shaped stepped shape. At the head end of each gripper 33, there are threaded holes for fixing to the clamping cylinder 32. At the end, there are also threaded holes for fixing gripper pads (not shown in the figure) adapted to the battery size, which is convenient for disassembly and installation and can flexibly adapt to different battery sizes; the gripper pads are made of ethylene propylene diene monomer (EPDM) to increase the grasping friction and ensure the battery clamping effect.

[0036] Compared with the traditional battery clamping device, the lithium battery clamping device in this embodiment has the following effects:

[0037] 1. Improve the compatibility and flexibility of the equipment

[0038] Traditional lithium battery clamping mechanisms are usually designed with jaws of a fixed spacing, which cannot solve the problem of the changing spacing of actual lithium battery production lines or trays. The lithium battery clamping device in this embodiment introduces a jaw variable-spacing device 2. Through the combination of a variable-spacing cylinder 21, a buffer 24, and a limit plate 23, rapid and precise adjustment of the jaw spacing is achieved. Operators can flexibly adjust the jaw spacing according to actual needs to ensure that the center distance between adjacent batteries matches that of the production line, improving the compatibility and flexibility of the equipment, reducing equipment adjustment time and costs, and enhancing production efficiency and quality.

[0039] 2. Enhance safety performance

[0040] In the traditional lithium battery clamping mechanism, there are potential safety hazards such as battery extrusion during improper operation or adjustment processes, which not only affect product quality but may also lead to production safety accidents. The lithium battery clamping device in this embodiment introduces a robotic arm device to detect and respond to abnormal situations in a timely manner. Through the mutual cooperation of an optoelectronic component 121 and an induction tooling 122, once battery extrusion or abnormal installation is detected, an alarm is immediately issued and a braking mechanism is triggered, effectively preventing battery damage or safety accidents caused by squeezing the battery and ensuring the safety of the production process.

[0041] 3. Improve product quality

[0042] Through the design of jaw pads, the jaws can be adapted to different-sized batteries, increasing the grasping friction and enhancing the adaptability of the equipment. At the same time, ethylene propylene diene monomer (EPDM) is selected as the material, which has good elasticity and wear resistance. While ensuring the battery clamping effect, it avoids damaging the battery surface and ensures product quality.

[0043] In summary, the lithium battery clamping device in this embodiment not only improves the compatibility and flexibility of the equipment, enhances production efficiency, and enhances safety performance, but also effectively solves the problems of poor compatibility, resource waste, and safety hazards in traditional technical solutions to meet the requirements of more efficient, safer, and more comprehensive equipment.
