Description

Technical Field

[0001] This utility model relates to the technical field of sodium-ion battery repair tools, and in particular to a tooling for removing the casing and repairing square sodium-ion batteries. Background Technology

[0002] During the pre-spot welding station, when pressing in the cover plate, the aluminum shell material may not be compatible with the cover plate. This can lead to deformation of the aluminum shell or the cover plate sinking into the aluminum shell, resulting in poor contours. If the gap between the cover plate and the aluminum shell is too small, it is difficult to remove manually during rework. The only options are to tap the cover plate's terminals or radius to remove it using inertia, or pull it out from the injection hole. Excessive force can damage the cover plate's terminals or the battery's internal components. In the square assembly line production process, the aluminum shell material may also be incompatible with the cover plate, causing deformation or sinking into the aluminum shell, resulting in poor contours. Manual rework often requires tapping the cover plate and using inertia to remove it, which can damage the cover plate. The resulting vibrations may also cause wrinkles or tears in the electrode tabs. Therefore, this invention improves upon existing equipment to address these problems. Utility Model Content

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0013] Example: See Figures 1 to 4 This utility model discloses a rework fixture for removing the casing of a square sodium-ion battery. The fixture includes a base 1, which is fixedly mounted on a horizontal working surface. A movable clamping arm 2 is located on the left side of the center of the top surface of the base 1, and a fixed clamping arm 3 is fixedly connected to the right side of the center of the top surface of the base 1. Both the fixed clamping arm 3 and the movable clamping arm 2 have baffle frames 4 at their upper opposite surfaces. The baffle frames 4 hold the casing 5 to be repaired. A clamping assembly is provided between the movable clamping arm 2 and the base 1. A locking assembly is located on the right side of the center of the top surface of the base 1. A sliding assembly is provided between the movable clamping arm 2, the fixed clamping arm 3, and the baffle frames 4. The movable clamping arm 2 and the baffle frame 4 are equipped with a spring-loaded component. The modular design facilitates device maintenance and upgrades, improving practicality. The clamping component includes a base 1. A sliding groove is opened on the left side of the top surface of the base 1. A first adjusting screw 6 is installed in the sliding groove. The left and right ends of the first adjusting screw 6 are rotatably connected to the base 1. A knob 7 is fixedly connected to the left end of the first adjusting screw 6. The outer side of the knob 7 has anti-slip texture. The bottom surface of the movable clamping arm 2 is fitted on the outer side of the first adjusting screw 6. The clamping distance can be adjusted independently to adapt to the separation of battery cases of different widths, improving practicality. In this utility model, to solve the problem of significant damage to the internal structure of the battery in existing separation technologies, the following technical solution is adopted: The positioning assembly includes a second adjusting screw 8, which is vertically fixed to the right side of the center of the top surface of the base 1. A screw-fitting sleeve 9 is fitted on the outer side of the second adjusting screw 8. Suction cups 10 are vertically fixed at equal intervals around the outer perimeter of the screw-fitting sleeve 9. The sliding assembly includes a slider 11, which is fixed to the front and rear sides of the upper end of the opposing surfaces of the movable clamping arm 2 and the fixed clamping arm 3. The other end of the slider 11 is slidably connected to a groove in the baffle frame 4. A damping pad 12 is attached, and a slider 11 abuts against the damping pad 12. The rebound assembly includes a baffle frame 4. A sleeve plate 13 is horizontally fixed to the lower left side of the baffle frame 4. A guide post 14 passes through the middle of the sleeve plate 13. The bottom end of the guide post 14 is fixed to the movable clamping arm 2. A spring 15 is provided between the movable clamping arm 2 and the sleeve plate 13. The spring 15 is sleeved on the guide post 14. Through the cooperation of the sliding assembly, the locking assembly and the rebound assembly, the aluminum shell and the cover plate are separated by inertia after an emergency stop. At the same time, the locking assembly is used to attract the cover plate, thereby reducing vibration and lateral friction on the internal battery, improving practicality.

[0014] Working Principle: When using this invention, firstly, rotate knob 7, which drives the first adjusting screw 6 to rotate in the groove on the left side of the top surface of the base 1, driving the movable clamping arm 2 to move away from the fixed clamping arm 3 along the groove. Then, place the battery to be repaired between the baffle frame 4 on the upper side of the opposite surfaces of the movable clamping arm 2 and the fixed clamping arm 3, so that the repair shell 5 is clamped by the baffle frame 4. Next, rotate knob 7 in the opposite direction, causing the first adjusting screw 6 to rotate in the opposite direction, driving the movable clamping arm 2 closer to the fixed clamping arm 3 until the battery to be repaired is clamped. At this time, the bottom of the battery to be repaired contacts the suction cup 10 fixed to the outside of the screw sleeve 9. At the same time, the socket plate 13 at the lower end of the left side of the baffle frame 4 moves downward along the guide post 14 under the pressure of the movable clamping arm 2, so that the spring 15 between the movable clamping arm 2 and the socket plate 13 is compressed. Afterwards, manually lift the battery to an appropriate height and release it. The battery will then move the baffle frame 4... As the battery moves downwards, the baffle frame 4 slides down along the slider 11 on the movable clamping arm 2 and the fixed clamping arm 3 through its groove. When the battery descends to contact the suction cup 10, the whole unit suddenly stops. Due to inertia, the left side of the battery cell inside the battery cover will continue to move downwards, causing the cover to tilt and detach from the aluminum shell. At the same time, the suction cup 10 connected to the screw sleeve 9 on the second adjusting screw 8 will hold the cover to reduce the rebound force generated by the collision. The compressed spring 15 will generate an upward elastic force, pushing the sleeve plate 13 to move upwards along the guide post 14, thereby driving the baffle frame 4 and the internal aluminum shell to move upwards, further promoting the separation of the cover from the aluminum shell. Under the action of the damping pad 12 in the groove, the separation distance between the cover and the aluminum shell is small, effectively reducing the vibration generated by the impact of the cover and the lateral friction of the internal battery. Finally, a quick, efficient and safe separation operation of the battery to be repaired is achieved.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
