Description

Technical Field

[0001] This utility model relates to the technical field of solid-state battery production equipment, specifically a winding rack for solid-state battery production. Background Technology

[0002] In solid-state battery production, the winding frame is a core piece of equipment used to wind the positive and negative electrodes, electrolyte membrane, and other components of the battery into a cell according to specific process requirements.

[0003] For example, an existing Chinese patent (CN221747293U) discloses a winding frame for solid-state battery production, including a base plate, a support column fixedly connected to the upper surface of the base plate, a top plate fixedly connected to the upper surface of the support column, a motor fixedly connected to the upper surface of the top plate, a rotating rod connected to the output shaft of the motor, and a turntable fixedly connected to the outer surface of the rotating rod. This invention, by starting the motor, causes the output shaft of the motor to drive the rotating rod to rotate, thereby driving the turntable to rotate. Due to the meshing of the toothed column, the connecting strip moves on the upper surface of the turntable, thereby causing the fixing plate and connecting plate to slide inside the fixing column. This allows adjustment of the distance between the three sets of fixing columns, enabling the electrolyte membrane to be secured between the three sets of fixing columns according to its size, facilitating the winding of the electrolyte membrane.

[0004] The aforementioned winding equipment uses a turntable to drive three sets of fixed posts to rotate and achieve the winding of the diaphragm. However, the winding path of this type of equipment is strictly dependent on the circumferential motion trajectory of the fixed posts, making it only suitable for producing cylindrical or elliptical cells. It is difficult to use the aforementioned existing equipment for prismatic solid-state batteries. Utility Model Content

[0021] 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.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a winding frame for solid-state battery production, comprising: an equipment cabinet 1, an electric turntable 3, and a winding shaft 5. The electric turntable 3 is mounted on the top of the equipment cabinet 1, ensuring structural stability and facilitating power supply and signal transmission through the equipment cabinet 1 to achieve precise rotational drive of the winding shaft 5. A T-slot 4 is provided on the top of the electric turntable 3. The design of the T-slot 4 and T-bolts 10 allows the installation position of the winding shaft 5 to be adjusted laterally along the slot, adapting to the winding requirements of solid-state batteries of different sizes, while ensuring stability after locking. T-bolts 10 are provided on both sides inside the T-slot 4. A vertical plate 11 is provided on one side of the top outer wall of the T-bolt 10, and a horizontal plate 12 is provided at the top of the vertical plate 11. The vertical plate 11 and the horizontal plate 12 form a support frame for the winding shaft 5. The frame can be moved laterally by adjusting the T-bolts 10, thereby adjusting the spacing of the winding shaft 5 to meet the geometric requirements of winding square batteries. The top of the horizontal plate 12 is provided with a threaded sleeve 13, and the top of the threaded sleeve 13 is provided with a winding shaft 5. The engagement of the threaded sleeve 13 with the external thread at the bottom of the winding shaft 5 enables quick disassembly and assembly of the winding shaft 5 and fine height adjustment, which is convenient for adapting to films of different thicknesses or adjusting the starting position of winding.

[0023] There are two T-bolts 10. A lower positioning plate 6 is fixed to the lower half of the outer wall of the winding shaft 5, and an upper positioning plate 7 is provided on the upper half of the outer wall of the winding shaft 5. The double T-bolts 10 are designed for winding square batteries. The lower positioning plate 6 is fixed to the lower half of the winding shaft 5, providing a bottom reference surface for the diaphragm and ensuring precise alignment of the winding start position. The upper positioning plate 7 can slide along the axial direction of the winding shaft 5, and its position can be adjusted to adapt to diaphragms of different heights. Together with the lower positioning plate 6, it restricts the axial movement of the diaphragm during the winding process.

[0024] There are two guide rollers 2 on one side of the top of the equipment cabinet 1, with a gap between them. The gap design of the double guide rollers 2 guides the film and ensures that the film enters the winding shaft 5 in a stable posture, avoiding deviation or wrinkles and improving the winding quality.

[0025] The bottom end of the winding shaft 5 is provided with an external thread that mates with the threaded sleeve 13. A locking nut 14 is provided on the outside of the external thread of the winding shaft 5, and the bottom surface of the locking nut 14 can abut against the top surface of the threaded sleeve 13. The engagement of the external thread and the locking nut 14 achieves axial locking of the winding shaft 5, preventing axial displacement caused by vibration or tension during the winding process and ensuring the geometric accuracy of the winding.

[0026] A fixing sleeve 8 is fixed to the center of the top of the upper positioning plate 7. A locking screw 9 is provided on one side of the fixing sleeve 8, and one end of the locking screw 9 abuts against the outer wall of the winding shaft 5. The combination of the fixing sleeve 8 and the locking screw 9 realizes the axial fixation of the upper positioning plate 7. The position of the upper positioning plate 7 can be finely adjusted by rotating the locking screw 9 to adapt to the winding requirements of films of different thicknesses.

[0027] The electric turntable 3 is driven by a servo motor. The servo motor drives the electric turntable 3 to achieve precise control of the rotation speed, direction, and start / stop of the winding shaft 5, meeting the tension requirements of different process stages such as acceleration, constant speed, and deceleration.

[0028] A scale line is provided on one side of the outer wall of the winding shaft 5. The scale line provides a visual reference for adjusting the upper positioning plate 7, making it easy for operators to quickly and accurately position the film winding height, reducing debugging time and improving production efficiency.

[0029] When using the winding frame in solid-state battery production, one end of the solid-state battery film is fixed to one of the winding shafts 5 between two guide rollers 2. After fixing, the bottom of the film is in contact with the lower positioning plate 6. The position of the upper positioning plate 7 is adjusted so that the bottom surface of the upper positioning plate 7 is in contact with the top of the film. Then, according to the size of the battery, the distance between the two winding shafts 5 is adjusted and locked with T-bolts 10. Then, the electric turntable 3 is started to drive the two winding shafts 5 to rotate, and the film is wound on the outside of the two winding shafts 5 to realize the film winding of the solid-state battery.

[0030] The design with two winding shafts 5 enables the winding operation of square batteries, while installing only one winding shaft also enables the winding operation of round batteries, greatly improving the applicability of the winding rack and making it suitable for winding operations of solid-state batteries of different shapes.

[0031] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
