The present utility model will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the utility model and structural, methodological, or functional modifications of these embodiments that may be made by one of ordinary skill in the art are included within the scope of the utility model.

The utility model provides a composite dust removing mechanism, a rear dust removing type cutting assembly and winding equipment, which are suitable for an application scene of removing dust on a pole piece before winding the pole piece into a battery core, and can remove foreign matters on the surface of the pole piece in various modes, so that the dust removing effect is optimized, and the product yield is improved.

In this embodiment, referring to fig. 1, the winding apparatus includes a positive unreeling component 1, a middle unreeling component 2, a negative unreeling component 3, a pressing component 4, a post dust removing cutting component 5, and a reeling component 6.

Specifically, the positive plate 701 is discharged from the positive unreeling component 1, the diaphragm 702 is discharged from the middle unreeling component 2, the negative plate 703 is discharged from the negative unreeling component 3, the positive plate 701, the diaphragm 702 and the negative plate 703 are pressed into the sheet-shaped battery cell 7a by the pressing component 4, the sheet-shaped battery cell 7a is subjected to dust removal by the rear dust removal type cutting component 5, and the sheet-shaped battery cell 7a after dust removal is wound into the roll-shaped battery cell 7b by the winding component 6. When the winding size of the rolled battery cell 7b reaches a predetermined size, the post-dust-removing cutting assembly 5 operates to cut off the sheet-like battery cell 7a and remove dust from foreign matter generated at the fracture.

In this embodiment, the rear dust-removing type cutting assembly 5 includes a cutter 501, a linear driving mechanism 502, an extension plate 503, and a composite dust-removing mechanism 504. Wherein, the driving end of the linear driving mechanism 502 is connected with the cutter 501 to drive the cutter 501 to approach or separate from the sheet-shaped battery cell 7a; one end of the extension plate 503 is fixedly connected with the cutter 501, and the other end is connected with the composite dust removing mechanism 504, so that the composite dust removing mechanism 504 is close to or far away from the chip-shaped battery cell 7a along with the cutter 501.

Optionally, the linear driving mechanism 502 is an air cylinder, a hydraulic cylinder, an electric cylinder, or a motor screw module, which is not limited in the present utility model.

Referring to fig. 2, the composite dust removing mechanism 504 includes a base plate 5041 mounted on an extension plate 503, an ultrasonic dust remover 5042 is mounted and fixed on the base plate 5041, and a brush 5043 and/or a magnet 5044 is mounted and fixed on the base plate 5041.

The ultrasonic dust remover 5042 can effectively remove small-size dust particles on the surface of the sheet-shaped battery cell 7a, does not need to use consumables such as pure water or chemical agents, does not need to be in direct contact with the sheet-shaped battery cell 7a, and avoids scratching the sheet-shaped battery cell 7a.

The brush 5043 and/or the magnet 5044 can firstly play a role in secondary or tertiary dust removal, and secondly can also effectively remove large-size dust particles or magnetic metal particles and the like which are difficult to clean by the ultrasonic dust remover 5042.

In this embodiment, the brush 5043 and the magnet 5044 are used simultaneously, that is: the brush 5043, the magnet 5044 and the ultrasonic dust remover 5042 are simultaneously arranged on the base plate 5041, so that dust particles and magnetic metal particles with various sizes are effectively removed.

In some other embodiments, the brush 5043 and the magnet 5044 may alternatively be used, i.e.: only the brush 5043 and the ultrasonic dust remover 5042 are mounted on the base plate 5041, so that various dust particles and foreign matters can be effectively removed, or only the magnet and the ultrasonic dust remover 5042 are mounted on the base plate 5041, so that magnetic metal particles and small-size dust particles can be effectively removed.

When the slice-shaped battery cell 7a is not needed to be cut, the slice-shaped battery cell 7a passes through the composite dust removing mechanism 504, and the hairbrush 5043 is not directly contacted with the slice-shaped battery cell 7a so as to prevent the slice-shaped battery cell 7a from being scratched, and at the moment, the ultrasonic dust remover 5042 and the magnet 5044 are mainly used for removing foreign matters; when the sheet-shaped battery cell 7a needs to be cut, the linear driving mechanism 502 drives the cutter 501 to cut the sheet-shaped battery cell 7a, the compound dust removing mechanism 504 is driven by the extension plate 503 to downwards approach the sheet-shaped battery cell 7a along with the cutter 501, and dust and the like generated during cutting can be cleaned by the brush 5043, the magnet 5044 and the ultrasonic dust remover 5042 simultaneously, so that the sheet-shaped battery cell 7a after being removed with dust by the compound dust removing mechanism 504 is not easy to cause bad due to foreign matters when being wound in the winding assembly 6.

Therefore, the compound dust removing mechanism provided by the embodiment can remove the foreign matters on the surface of the pole piece in various modes, so that the dust removing effect is optimized, and the product yield is improved.

Alternatively, the composite dust removing mechanism 504 is provided with a fastening hole 5041a fastened to the extension plate 503, and the composite dust removing mechanism 504 can be fastened to the extension plate 503 by passing a fastening member such as a fastening bolt through the extension plate 503 and the fastening hole 5041 a.

Optionally, the composite dust removing mechanism 504 is provided with a first absorbing member 8, and the extension plate 503 is provided with a second absorbing member 9; the first absorbent member 8 and the second absorbent member 9 are magnetically connected. For example, the first absorbing member 8 may be a magnet and the second absorbing member 9 may be a iron block, or the first absorbing member 8 may be a iron block and the second absorbing member 9 may be a magnet.

Before the fastener is tightened, the first absorbing member 8 and the second absorbing member 9 may be magnetically connected to complete the relative positioning of the extension plate 503 and the base plate 5041, and then the fastener is tightened to improve the installation efficiency. Of course, if the magnetic action between the first absorbing member 8 and the second absorbing member 9 is sufficient to meet the design requirement, the fastening member may be omitted, and the connection between the extension plate 503 and the composite dust removing mechanism 504 is realized only by the magnetic action between the first absorbing member 8 and the second absorbing member 9, so as to facilitate the assembly, disassembly and maintenance of the composite dust removing mechanism 504.

In this embodiment, the composite dust removing mechanism 504 further includes a gas blowing hole 5045 for removing dust by blowing. Further, the air blowing hole 5045 penetrates through the base plate 5041 and the ultrasonic dust collector 5042, so that the structural design can reduce the extra space occupied by the air blowing hole, thereby being beneficial to reducing the volume of equipment and improving the compactness of the structure. In some other embodiments, the air outlet may extend through only the substrate 5041 and be located between the magnet 5044 and the brush 5043 or between the brush 5043 and the ultrasonic dust collector 5042, which is not limited in the present utility model.

In this embodiment, the brush 5043 is a roller brush, and the brush 5043 is rotatably connected with the substrate 5041, so as to reduce friction resistance between the brush 5043 and the sheet-shaped battery cell 7a, and further reduce damage to the sheet-shaped battery cell 7a.

Further, the number of the brushes 5043 is two, the number of the magnets 5044 is two, and the number of the ultrasonic dust collectors 5042 is one; the ultrasonic dust collector 5042 is located between the two brushes 5043, and the two brushes 5043 are located between the two magnets 5044. Symmetrical structural layout is favorable for improving the uniformity during dust removal operation, and then the dust removal effect is improved.

The compound dust removal mechanism 504, back dust removal formula cutting assembly 5 and winding equipment that this embodiment provided possess following beneficial effect:

(1) the sheet-shaped battery cell 7a is subjected to dust removal operation in at least two dust removal modes including ultrasonic dust removal, so that the problem that the existing dust removal device is poor in dust removal effect due to the fact that the dust removal means are too single is effectively solved;

(2) the composite dust removing mechanism 504 is close to or far away from the sheet-shaped battery cell 7a along with the cutter 501, so that the surface of the sheet-shaped battery cell 7a is less scratched and damaged as much as possible while the maximum dust removing effect is ensured;

(3) the composite dust removing mechanism 504 is arranged at the rear of the cutter 501, so that foreign matters generated when the cutter 501 cuts are conveniently cleaned.
