A high degree of automation has become one of the important indicators for measuring the advancement of the battery manufacturing industry. In the manufacturing process of pouch batteries, robotic arms are typically needed to precisely grip and transfer the batteries; therefore, a pouch battery gripper mechanism is required to handle these batteries.

[0003] The prior art, disclosed in CN221792746U, discloses a gripper mechanism for a soft-pack battery, which "includes a mounting frame, a first gripper mechanism, and a second gripper mechanism; the mounting frame includes a top plate and a robot connecting seat; the first gripper mechanism includes a first mounting plate, four first upright plates, and a first gripper group, the first upright plates are slidably connected to the top plate along the Z-axis direction, the first gripper group includes a plurality of first pneumatic grippers, and photoelectric switches are installed on the first pneumatic grippers; the second gripper mechanism includes a second mounting plate, four second upright plates, and two second gripper groups symmetrically arranged on both sides of the first gripper group, the second upright plates are slidably connected to the first mounting plate along the Z-axis direction, the second gripper groups include a plurality of second pneumatic grippers, and longitudinal drive cylinders that are drivenly connected to the second mounting plates are provided on both sides of the top of the top plate, and a through groove is provided in the middle of the second mounting plate"; The aforementioned gripper mechanism can grip soft-pack batteries, but the main body of a soft-pack battery usually has an air bag formed by aluminum-plastic film encapsulation on one side. This air bag is mainly used for battery electrolyte injection and venting. Its material is relatively soft and easily deformed, and it is very sensitive to external forces. During the descent or gripping process, the front end or side of the robot arm is very likely to collide or scratch with the air bag on the side of the battery, causing the air bag to deform, break or even become contaminated, which seriously affects the appearance integrity and encapsulation quality of the battery, and may even cause safety problems such as electrolyte leakage. At the same time, the limiting effect is poor when gripping soft-pack batteries, which can also easily cause damage to the battery or air bag. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a soft-pack battery gripper mechanism, which more accurately solves the problem that existing gripper mechanisms are prone to colliding with soft-pack batteries and have poor limiting effect during descent or gripping.

[0016] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0017] Please refer to Figures 1-5 This utility model proposes a soft-pack battery gripper mechanism, including a flange plate 1, which is connected to a robotic arm. A fixing plate 2 is bolted to the bottom of the flange plate 1. A gripping assembly is provided below the fixing plate 2 for gripping the soft-pack battery. The surface of the fixing plate 2 has multiple sets of first mounting holes 3 for fixing the fixing plate 2 to a mounting plate 5 or other structures. All sets of first mounting holes 3 are elliptical in shape. A barcode scanner 4 is installed on the side wall of the fixing plate 2 for scanning and identifying the tray containing the soft-pack battery.

[0018] The clamping assembly includes two sets of mounting plates 5, which are symmetrically mounted on the bottom of the fixed plate 2 by bolts. Each mounting plate 5 has a second mounting hole 6 for mounting and fixing. A first cylinder 7 is bolted to the bottom of each mounting plate 5 to move the cylinder opening structure 9. A magnetic switch 8 is mounted on the side wall of the first cylinder 7 to control the opening degree of the cylinder opening structure 9, thereby controlling the clamping force. The output end of the first cylinder 7 is mounted with the cylinder opening structure 9 to fold the battery gripper 10. The bottom of the cylinder opening structure 9 is bolted with a battery gripper 10 to clamp the battery body. The end side wall of the battery gripper 10 is bolted... Equipped with a protective horizontal bar 11, which is made of non-metallic material, the protective horizontal bar 11 can increase the contact area with the battery body, increase the clamping force, and ensure the stable clamping of the battery gripper 10. The cylinder opening structure 9 is rotatably connected to the housing of the first cylinder 7. In the initial state, the battery gripper 10 is horizontally open to avoid touching the battery body, reducing the safety risk during the battery clamping process and improving operational safety and production efficiency. After the air bag gripper 15 clamps the air bag and rises to a certain height, the first cylinder 7 is activated. The first cylinder 7 moves, causing the cylinder opening structure 9 to change from a horizontal state to a vertical state. The change of the cylinder opening structure 9 causes the battery gripper 10 to fold, which can clamp the battery body and thus safely and stably clamp the battery.

[0019] The clamping assembly also includes a mounting bracket 12, which is bolted to the bottom of the mounting plate 5. A second cylinder 13 is bolted to the bottom of the mounting bracket 12 to move the sliding block 14. A magnetic switch 8 is also installed inside the second cylinder 13, with each magnetic switch corresponding to a clamping claw. Two sets of sliding blocks 14 are symmetrically mounted on the bottom of the second cylinder 13. Air bag clamping claws 15 are bolted to the bottom of each sliding block 14 to clamp the battery air bag. The second cylinder 13 is a split rodless cylinder. Anti-slip grooves are formed on the surface of the air bag clamping claws 15. A photoelectric switch 16 is installed on the side wall of the air bag clamping claws 15 to sense whether the air bag clamping claws 15 have clamped the air bag. Both ends of the mounting bracket 12 are bolted with buffer blocks 17 for fixing the buffer 18. The buffer block 17 is threaded with the buffer 18 to buffer the movement of the sliding block 14 and the air bag gripper 15. In the initial state, the air bag gripper 15 and the buffer 18 are in contact. When gripping the battery, the robot arm drives the battery gripper 10 and the air bag gripper 15 to move downward. After moving to the appropriate position, the second cylinder 13 is activated. The second cylinder 13 causes the two sets of sliding blocks 14 to move closer to each other. The movement of the sliding blocks 14 drives the air bag gripper 15 to move, which can grip the battery air bag. With the cooperation of the photoelectric switch 16, the situation of empty gripping is avoided.

[0020] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
