Description

Technical Field

[0001] This utility model relates to the field of battery cell assembly box technology, specifically a battery cell assembly box fixture. Background Technology

[0002] This cell module assembly box fixture is mainly used in automated production lines for lithium battery modules, especially in the assembly process of square and cylindrical cell modules and battery pack shells. It is suitable for batch packing operations of everything from passenger car power batteries to large battery modules for energy storage power stations.

[0003] Traditional clamps often employ pneumatic rigid clamps, using cylinders as the power source and paired with rigid metal clamping plates (without elastic cushioning). The opening and closing of the clamping plates are controlled by pneumatic valves. Although this solves the fundamental problem of "low efficiency of manual clamps," the rigid structure design has significant limitations when adapting to the high-precision, low-damage, and multi-specification assembly requirements of lithium battery modules. It cannot effectively adapt to battery cell modules with different shapes. This paper proposes a battery cell module assembly box clamp to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a battery cell mold assembly box fixture, which solves the problem of clamping and fixing the battery cell mold assembly box during processing.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a battery cell module assembly box fixture, including a lower frame, an installation box fixedly connected to one side of the upper surface of the lower frame, a fixing plate fixedly connected to the upper surface of the installation box, a clamping device fixedly connected to the upper surface of the fixing plate, positive and negative threaded rods fixedly connected to both sides of the inner wall of the fixing plate, a motor fixedly connected to the middle of the back side of the fixing plate, and a placement groove fixedly connected to the other side of the upper surface of the lower frame; The clamping device includes a clamping shell, on both sides of which are fixedly connected moving blocks adapted to the forward and reverse threaded rods. The bottom of the clamping shell is slidably connected to a limiting slide plate connected to a fixed plate. Several sleeves are fixedly connected to the inner wall of the clamping shell, and connecting rods are sleeved on the inner wall of the sleeves.

[0006] Preferably, a spring connected to a sleeve is fixedly connected to the bottom of the connecting rod, a clamping rod is fixedly connected to the top of the connecting rod, and an elastic connecting rope is fixedly connected to the inner wall of the clamping rod.

[0007] Preferably, the output end of the motor and one side of the positive and negative threaded screws are both connected to transmission gears via belt drive, and a protective shell is fixedly connected to the back of the fixing plate.

[0008] Preferably, an upper frame is fixedly connected to the upper surface of the lower frame, and an electric slide rail is fixedly connected to the top of the inner wall of the upper frame.

[0009] Preferably, a movable frame is fixedly connected to the outer surface of the electric slide rail, and an air pump is fixedly connected to the middle of the upper surface of the movable frame.

[0010] Preferably, electric telescopic rods are fixedly connected to both sides of the lower surface of the movable frame, and an installation frame is fixedly connected to the bottom of the electric telescopic rods.

[0011] Preferably, the output end of the suction pump is fixedly connected to a spring air tube, the bottom of the spring air tube is fixedly connected to a suction tube, and the output end of the suction tube is fixedly connected to several suction cups connected to the mounting frame.

[0012] This utility model provides a battery cell mold assembly box fixture. Compared with the prior art, it has the following advantages: 1. This battery cell module assembly fixture uses a spring and elastic connecting rope in the clamping device to form a flexible buffer structure. When there are slight dimensional tolerances in the battery cell module, the spring can adaptively adjust the clamping force through compression and rebound, avoiding module deformation caused by rigid clamping. The clamping rods are connected in series by the elastic connecting rope to ensure that the clamping rods will not deviate and get stuck, ensuring that the module does not shift during gripping and transfer, and reducing packing failures caused by dimensional deviations.

[0013] 2. This battery cell module assembly fixture uses a motor-driven clamping mechanism, an air pump for vacuum adsorption, an electric slide rail for cross-station transfer, and an electric telescopic rod for lifting. All components are linked by electrical signals, eliminating the need for manual handling of modules or manual position calibration. The multi-suction cup array adsorption evenly distributes the suction force on the module's surface, preventing single-point compression. Furthermore, the suction cups are made of anti-static flexible material to avoid electrostatic damage to the battery cell diaphragm or scratching of the module surface. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1 to 7 This utility model provides a technical solution: a battery cell module assembly box fixture, including a lower frame 1, an installation box 2 fixedly connected to one side of the upper surface of the lower frame 1, a fixing plate 3 fixedly connected to the upper surface of the installation box 2, a clamping device 4 fixedly connected to the upper surface of the fixing plate 3, positive and negative threaded rods 5 fixedly connected to both sides of the inner wall of the fixing plate 3, a motor 6 fixedly connected to the middle of the back of the fixing plate 3, and a placement groove 9 fixedly connected to the other side of the upper surface of the lower frame 1; The clamping device 4 includes a clamping shell 401. Movable blocks 402 adapted to the positive and negative threaded rods 5 are fixedly connected to both sides of the clamping shell 401. A limiting slide plate 403 connected to the fixed plate 3 is slidably connected to the bottom of the clamping shell 401. Several sleeves 404 are fixedly connected to the inner wall of the clamping shell 401. A connecting rod 405 is sleeved on the inner wall of the sleeve 404. A spring 406 connected to the sleeve 404 is fixedly connected to the bottom of the connecting rod 405. A clamping rod 407 is fixedly connected to the top of the connecting rod 405. An elastic connecting rope 408 is fixedly connected to the inner wall of the clamping rod 407. A transmission gear 7 is connected to the output end of the motor 6 and one side of the positive and negative threaded rods 5 through belt drive. A protective shell 8 is fixedly connected to the back of the fixed plate 3.

[0018] By activating the motor 6 on the back of the fixing plate 3, the output end of the motor 6 generates rotational power, providing the power basis for the subsequent movement of the clamping device 4. The power of the motor 6 is transmitted to the positive and negative thread screw 5 through the belt, and the inner thread of the moving block 402 of the clamping device 4 is adapted to the screw. Therefore, when the screw rotates, it will drive the moving blocks 402 on both sides to move synchronously in opposite directions. The limiting slide plate 403 restricts the movement direction of the clamping shell 401, ensuring that the clamping shells 401 on both sides move stably closer or further away from the surface of the fixing plate 3 under the drive of the screw. When the clamping shell 401 approaches the battery cell module, the clamping rod 407 first contacts the module surface. Since the clamping rod 407 is sleeved with the sleeve 404 through the connecting rod 405, and the connecting rod 405 is connected to the sleeve 404, the clamping rod 407 is connected to the battery cell module. The bottom of the connecting rod 405 is connected to the sleeve 404 by a spring 406. Therefore, the impact force at the moment of contact will compress the spring 406, causing the connecting rod 405 to retract into the sleeve 404, thus avoiding the clamping force from acting directly and rigidly on the battery cell. The compression of the spring 406 varies with the clamping force. If there is a slight deviation in the module size, the spring 406 will be further compressed to compensate for the deviation through elasticity, ensuring that the clamping rod 407 is always in contact with the module surface, while avoiding pressure overload. If the module size is slightly thin, the spring 406 will rebound and push the connecting rod 405 to extend, ensuring sufficient clamping force and preventing the module from loosening. The clamping rod 407 is connected in series by an elastic connecting rope 408 to ensure that the clamping rod 407 will not deviate and get stuck or deformed.

[0019] like Figures 1 to 7 As shown, an upper frame 10 is fixedly connected to the upper surface of the lower frame 1. An electric slide rail 11 is fixedly connected to the top of the inner wall of the upper frame 10. A movable frame 12 is fixedly connected to the outer surface of the electric slide rail 11. An air pump 13 is fixedly connected to the middle of the upper surface of the movable frame 12. Electric telescopic rods 14 are fixedly connected to both sides of the lower surface of the movable frame 12. A mounting frame 15 is fixedly connected to the bottom of the electric telescopic rods 14. A spring air pipe 16 is fixedly connected to the output end of the air pump 13. An air suction pipe 17 is fixedly connected to the bottom of the spring air pipe 16. Several suction cups 18 connected to the mounting frame 15 are fixedly connected to the output end of the air suction pipe 17.

[0020] The electric slide rail 11 on the top inner wall of the upper frame 10 is laid along the direction directly above the clamping device 4 and the placement slot 9, providing a fixed path for the subsequent movement of the moving frame 12, ensuring that the module will not deviate from the packing position during handling. The moving frame 12 is fixed to the outer surface of the electric slide rail 11 and can move with the slide rail. Its lower surface is used to install subsequent gripping components such as the electric telescopic rod 14 and suction cup 18, while the suction pump 13 on the upper surface provides vacuum power for the suction cup 18. When the moving frame 12 reaches directly above the module, the electric telescopic rod 14 is energized and extends. 15 is fixed to the bottom of the electric telescopic rod 14, and the suction cup 18 is mounted on the mounting frame 15. Therefore, when the telescopic rod extends, it will drive the suction cup 18 to move downward until it contacts the upper surface of the module. The negative pressure generated by the suction pump 13 is transmitted to the suction pipe 17 through the spring air pipe 16. The spring air pipe 16 can deform freely with the extension and retraction of the electric telescopic rod 14 to avoid the air pipe from breaking due to stretching or compression. When the suction cup 18 contacts the upper surface of the module, the air in the suction cup 18 is drawn away by the negative pressure to form a vacuum chamber. The atmospheric pressure presses the suction cup 18 tightly against the surface of the module to achieve stable gripping of the module.

[0021] During operation or use, the battery cell module assembly box fixture first requires the operator or upstream production line to place the box to be boxed into the placement slot 9 of the lower frame 1. The electric slide rail 11 is powered on and started, driving the moving frame 12 on the outer surface to slide along the slide rail until the suction cup 18 below the moving frame 12 is directly above the battery cell module being clamped. The electric telescopic rod 14 is powered on and extends, driving the mounting frame 15 at the bottom and the suction cup 18 to move downward synchronously. The suction cup 18 makes full contact with the upper surface of the module, achieving stable adsorption of the module and moving the module to the clamping position.

[0022] The motor 6 on the back of the fixed plate 3 is started. The transmission gear 7 at the output end of the motor 6 drives the forward and reverse threaded rods 5 to rotate synchronously via the belt. When the threaded rods rotate, they will drive the moving blocks 402 on both sides to move synchronously in the opposite direction along the limiting slide plate 403. The clamping shells 401 on both sides move closer to the battery cell module in the middle. When the clamping rod 407 inside the clamping shell 401 contacts the surface of the module, the module generates a reaction force on the clamping rod 407, pushing the connecting rod 405 to retract into the sleeve 404, compressing the spring 406 at the bottom. The elastic force of the spring 406 is transmitted to the clamping rod 407 through the connecting rod 405, forming a flexible clamping force. This avoids damage to the battery cell from rigid contact and can adaptively compensate for module size deviations through the compression of the spring 406, ensuring that the module is stably clamped.
