Technical Field

[0001] The utility model relates to the technical field of battery processing, in particular to a cylindrical battery core flattening device. Background Art

[0002] The battery cell is the most important component of the battery. The battery cell can only be assembled into a battery after it has been processed through mechanical / ultrasonic flattening, encapsulation, shelling, collector plate welding and other processes. Therefore, the performance of the battery cell has a direct impact on the performance of the battery. The battery cell preparation process before battery assembly is very important. At present, a mechanical flattening head is mainly used to flatten the horizontally distributed battery cells. The various moving parts of the flattening machine will produce friction during operation, which will reduce the service life of the flattening head. At the same time, the friction and vibration between the parts and the noise generated have a lot of impact on the working environment. In addition, considering that during the mechanical flattening process, crushed dust and other debris will appear on the end face of the battery cell, in order to prevent these dusts from entering the positive or negative terminal of the battery cell, a dust suction structure is usually configured on the mechanical flattening head to vacuum the debris generated during the mechanical flattening process.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 6 The utility model provides a technical solution: a cylindrical battery core flattening device, including a driving seat 1 and a flattening mechanism, a side of the driving seat 1 is provided with a fixedly connected rotating disk 2; the flattening mechanism, the flattening mechanism includes a flattening head 4 and a bearing seat 3, the flattening head 4 is rotatably connected to the bearing seat 3, the bearing seat 3 is fixedly connected to the rotating disk 2, the flattening head 4 cooperates with the filling component, when the flattening head 4 rotates, the filling component can be lubricated.

[0023] More specifically, the supporting seat 3 includes a rotating hole 13 which is arranged through the side, and the kneading head 4 can rotate in the rotating hole 13. A liquid storage sleeve 8 is fixedly connected to the side of the supporting seat 3. A leakage groove 15 is arranged on the upper end of the liquid storage sleeve 8. There is a gap between the leakage groove 15 and the kneading head 4. When the kneading head 4 rotates, a negative pressure space is formed between the leakage groove 15 and the kneading head 4. In the negative pressure space, air will flow from the high-pressure area to the low-pressure area, forming a negative pressure difference, and the lubricating oil will be driven to the surface of the kneading head 4 to form an oil film. When the kneading head 4 rotates faster, more lubricating oil will be brought up, so that it can be automatically adjusted according to the work efficiency.

[0024] Furthermore, the residue suction port 14 uses suction to suck away the residue adhered to the lubricating oil generated when the flattening head 4 starts working, so that the flattening head 4 can work to reduce the influence of the residue on the work. The liquid storage sleeve 8 includes a residue suction port 14 at the upper end, and a suction pipe 16 connected to the residue suction port 14 is provided at the bottom of the residue suction port 14. The bottom of the suction pipe 16 is connected to the exhaust pipe 9. When the flattening head 4 starts to work and rotate, the residue suction port 14 will suck away the stains attached to the surface of the flattening head 4, so that the surface of the flattening head 4 is clean, thereby enhancing the effect of the flattening work.

[0025] Furthermore, the liquid storage sleeve 8 also includes a connecting column 11 arranged on the side, and the connecting column 11 and the side of the bearing seat 3 are provided with holes that match the connecting column 11, so that the two can be fixedly connected.

[0026] Specifically, the dust suction port 5 is the total dust suction hole, which is set to a larger diameter. It adopts a horizontal kneading and precise dust suction structure with the kneading part of the equipment. The kneading position is coaxial with the dust suction port and the distance is close. Dust is sucked while kneading, which ensures the dust suction effect of kneading. The rotating disk 2 includes a threaded hole 12 and a dust suction port 5 arranged on the side. The threaded hole 12 is fixedly connected to the bottom of the bearing seat 3 with bolts. A dust suction fan 6 is arranged inside the dust suction port 5. When the rotating disk 2 rotates and the kneading head 4 works, the dust suction port 5 can suck away fine dust, which can reduce the scattering of harmful substances.

[0027] Specifically, the bearing seat 3 also includes a bearing seat 7 arranged on the side, the bearing seat 7 is rotatably connected to the flattening head 4, and the bearing inside the bearing seat 3 is used for the self-rotation formed by the friction force generated by the flattening head 4 during flattening, thereby reducing the friction between the flattening head and the foil.

[0028] Furthermore, a liquid outlet hole is provided on the inner wall of the leakage groove 15. When the flattening head 4 rotates, the lubricating oil enters the inner wall of the leakage groove 15 through the liquid outlet hole and adheres to the outer surface of the flattening head 4. The lubricating oil on the inner wall of the leakage groove 15 flows out through the liquid outlet hole. When a negative pressure space state is generated, the liquid outlet hole will continuously replenish the leakage groove.

[0029] Furthermore, the liquid storage sleeve 8 also includes a wind block plate 17 arranged at the upper end, and the wind block plate 17 is located between the slag suction port 14 and the negative pressure space. The wind block plate 17 is designed to prevent the oil film on the surface of the kneading head 4 from being sucked while the slag suction port 14 is sucking slag, thereby achieving the effect of reducing the waste of lubricating oil.

[0030] A method for flattening a cylindrical battery core comprises the following steps:

[0031] S1: When the smoothing mechanism is working, the driving seat 1 drives the rotating disk 2 to rotate, so that the smoothing head 4 rotates;

[0032] S2: When the kneading head 4 rotates, a negative pressure space is formed between the kneading head 4 and the leakage groove 15, and the lubricating oil is driven to the surface of the kneading head 4 to form an oil film;

[0033] S3: When an oil film is formed on the surface of the flattening head 4, the slag suction port 14 is opened to suck the residue on the surface of the flattening head 4. While sucking the residue, the wind blocking plate 17 prevents the slag suction port 14 from sucking the oil film.

[0034] The utility model utilizes the above structure to add an oil film to the surface of the flattening head 4 when it is working to reduce friction and noise, and at the same time, the residue is sucked through the residue suction port 14 to increase the service life of the machine.

[0035] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.
