Description

Technical Field

[0001] The present application relates to the field of battery production technology, and in particular to a burr grinding device for slitting battery pole pieces and battery production equipment. Background Art

[0002] At present, the lithium-ion wound cell structure has the advantages of relatively high energy density, good heat dissipation performance, and preparation reliability, and is widely used as a production and preparation method for lithium batteries. The quality of the cell determines the recycling and safety reliability of the lithium battery.

[0003] Currently, during the slitting process of wound-type battery cells, abnormal burrs are generated during the slitting process due to factors such as the service life of the cutter, tool defects, and improper knife adjustment. Since there is a certain amount of protrusion between the cathode and anode plates in the battery cell structure design, if there is a burr on the cathode plate, it is easy to puncture the diaphragm and overlap the anode, thereby causing an internal short circuit in the battery cell. Therefore, during the production of wound-structured battery cells, the slitting edges of the cathode plates need to be deburred. However, the existing battery production equipment has a fast production cycle and the winding battery cell has a high degree of automation. Due to the low efficiency of burr removal, it is difficult to improve battery production efficiency. Utility Model Content

[0039] Generally speaking, the lithium-ion wound cell structure has the advantages of relatively high energy density, good heat dissipation performance, and manufacturing reliability, and is widely used as a production method for lithium batteries. The quality of the cell determines the recycling, safety and reliability of the lithium battery.

[0040] Currently, during the slitting process of wound-type battery cells, burrs are generated during the slitting process due to factors such as the life of the cutter, tool defects, and improper knife adjustment. Since there is a certain amount of protrusion between the cathode and anode electrodes in the battery cell structure design, burrs on the cathode electrode can easily puncture the diaphragm and overlap the anode, causing an internal short circuit in the battery cell. Therefore, during the production of wound-structured batteries, the cathode electrode edges need to be deburred. At the same time, due to the high degree of automation of wound batteries and the fast production cycle of equipment, the existing equipment is inefficient in removing burrs, making it difficult to improve battery production efficiency.

[0041] In response to the technical problems raised above, the embodiments of the present application provide a burr grinding device for battery pole piece slitting and a battery production equipment, which can achieve the efficiency of burr removal without affecting production efficiency; see Figure 1 , Figure 1 A schematic structural diagram of a burr grinding device for slitting a battery electrode provided in an embodiment of the present application; the burr grinding device for slitting a battery electrode comprises a bracket 100, a slitting mechanism 200, a grinding assembly 300, and a dust collection assembly 400;

[0042] Exemplarily, the slitting mechanism 200 is mounted on the bracket 100 , and the slitting mechanism 200 is provided with a slitting tool 210 , which is used to slit the battery electrode sheet 500 to be processed;

[0043] For example, the battery electrode 500 to be processed is transported to the slitting mechanism 200 for slitting, as shown in FIG. Figure 1 The conveying mechanism shown may be an unwinding device;

[0044] Optionally, the slitting mechanism 200 may include one slitting tool 210 or multiple slitting tools 210. The number of slitting tools 210 may be set according to actual needs. It should be noted that in the embodiment of the present application, Figure 1 The number of slitting knives 210 shown is one, which is only used as an example for description and does not limit the number of slitting knives 210 .

[0045] Exemplarily, the grinding assembly 300 includes at least one grinding mechanism 310, which is disposed on the bracket 100 and is disposed on the rear side of the slitting mechanism 200 along the conveying direction of the battery electrode sheet 500 to be processed. The grinding mechanism 310 is matched with the cut edge of the battery electrode sheet 500 to be processed.

[0046] For example, the slitting mechanism 200 and the grinding mechanism 310 are arranged in front and behind along the conveying direction of the battery pole piece 500 to be processed, so that after the slitting mechanism 200 cuts the battery pole piece 500 to be processed, the grinding mechanism 310 can grind the cut edges of the battery pole piece 500 to be processed passing at a high speed by the grinding mechanism 310, so that burrs can be efficiently removed by the grinding mechanism 310.

[0047] Exemplarily, the dust collection assembly 400 includes at least one dust collection mechanism 410, which is disposed on the bracket 100 and is disposed on the rear side of the grinding mechanism 310 along the conveying direction of the battery electrode sheet 500 to be processed. The dust collection mechanism 410 is matched with the surface of the battery electrode sheet 500 to be processed.

[0048] Illustratively, the grinding mechanism 310 and the dust collection mechanism 410 are arranged in front and behind along the conveying direction of the battery electrode 500 to be processed, so that after the grinding mechanism 310 grinds the cut edge of the battery electrode 500 to be processed, the dust collection mechanism 410 can perform dust collection and cleaning on the surface of the battery electrode to be processed to prevent foreign matter that may be splashed, ensure that no new foreign matter is introduced on the surface of the battery electrode to be processed, ensure that the surface of the battery electrode to be processed is clean, and the processed battery electrode continues to be pulled by rollers for subsequent operations such as winding.

[0049] In some embodiments, there is a corresponding relationship between the number of slitting tools 210 and the number of grinding mechanisms 310 and the number of dust collection mechanisms 410; for example, the number of slitting tools 210 is N, and the slitting tools 210 can be used to cut the battery poles to be processed into N+1 battery poles, then the number of grinding mechanisms and the number of dust collection mechanisms 410 are both N+1, which are set corresponding to the N+1 battery poles.

[0050] In some embodiments, the burr grinding device for slitting the battery pole piece is directly introduced into the deburring tool after the battery pole piece 500 to be processed is slit by the slitting mechanism 200, that is, the cutting edge of the battery pole piece passing at high speed is polished by setting a polishing mechanism 310, and the polishing mechanism 310 can efficiently remove the cutting edge burrs of the battery pole piece; at the same time, a dust suction mechanism 410 is set after the polishing mechanism 310, and the dust suction mechanism 410 can conveniently absorb foreign matter that falls on the surface of the battery pole piece, thereby ensuring that the surface of the battery pole piece is clean and does not affect the normal winding of the battery pole piece; thus, the burr grinding device for slitting the battery pole piece can improve the technical effect of the efficiency of removing burrs after the battery pole piece is slitting.

[0051] See Figure 2 , Figure 2 A schematic diagram of the grinding mechanism provided in an embodiment of the present application.

The grinding disc 311 abuts against the cut edge of the battery electrode 500 to be processed, and the first negative pressure suction cup 312 is installed on the outer side of the grinding disc 311 .

[0053] For example, the grinding disc 311 of the grinding mechanism 310 is used to grind the cut edges of the battery pole pieces passing at high speed, so that the burrs generated after cutting can be directly removed; at the same time, a first negative pressure suction cup 312 is set on the outside of the grinding disc 311, and foreign matter that may be generated by the grinding of the grinding disc 311 can be sucked away by the first negative pressure suction cup 312, thereby effectively preventing the generation of flying foreign matter and falling into the pole piece, and effectively ensuring the cleanliness of the battery pole piece.

[0054] Exemplarily, the grinding mechanism 310 further includes a first slide rail 313 and a distance sensor. The first slide rail 313 is mounted on the bracket 100 , and the grinding disc 311 is slidably mounted on the first slide rail 313 . The distance sensor is mounted on the first slide rail 313 .

[0055] Exemplarily, the grinding wheel 311 is slidably mounted on the first slide rail 313, and the distance sensor can measure and determine the distance between the cut edge of the battery electrode and the grinding wheel 311, so that the grinding wheel 311 is adjusted to a suitable position under the action of the slide rail to ensure the grinding efficiency of the grinding wheel 311 on the cut edge of the battery electrode.

[0056] Exemplarily, the first negative pressure suction cup 312 is a bell-shaped negative pressure suction cup, which is arranged at a preset outer ring chamfer distance of the grinding disc 311 .

[0057] For example, the trumpet-shaped negative pressure suction cup can more effectively absorb foreign matter that is splashed when the grinding disc 311 is grinding the battery electrode.

[0058] See Figure 3 , Figure 3 A schematic structural diagram of the dust collection mechanism provided in an embodiment of the present application.

[0059] Exemplarily, the dust suction mechanism 410 includes a second negative pressure suction cup 411 and a dust removal brush 412 . The dust removal brush 412 is installed inside the second negative pressure suction cup 411 . The second negative pressure suction cup 411 is arranged on the surface in the forward direction of the battery electrode 500 to be processed.

[0060] For example, a second negative pressure suction cup 411 is installed on the surface of the battery electrode 500 to be processed in the forward direction, and a dust removal brush 412 is provided inside the second negative pressure suction cup 41, which can effectively remove foreign matter that may splash and fall onto the surface of the battery electrode, further ensuring the surface cleanliness of the battery electrode.

[0061] Exemplarily, the dust collection mechanism 410 further includes a second slide rail 413 , which is mounted on the bracket 100 , and the second negative pressure suction cup 411 is slidably mounted on the second slide rail 413 .

[0062] Exemplarily, the second negative pressure suction cup 411 is slidably mounted on the second slide rail 413 so as to adjust the vertical or horizontal sliding distance between the second negative pressure suction cup 411 and the surface of the battery electrode.

[0063] Exemplarily, the dust suction mechanism 410 further includes an insert, and the second negative pressure suction cup 411 is slidably mounted on the second slide rail 413 via the insert.

[0064] Exemplarily, the insert is connected to the second slide rail 413 to facilitate position adjustment of the second negative pressure suction cup 411 .

[0065] Exemplarily, the dust removal brush 412 is a snap-on dust removal brush.

[0066] For example, the snap-on dust removal brush can be easily replaced when needed, thereby improving the maintainability of the burr grinding device for slitting the battery pole pieces.

[0067] Exemplarily, the burr grinding device for slitting battery pole pieces further includes a plurality of conveying roller mechanisms 600 , which are arranged between the slitting mechanism 200 and the grinding assembly 300 , or between the grinding assembly 300 and the dust collection assembly 400 .

[0068] Exemplarily, the forward conveyance of the battery pole piece is achieved by the conveying roller mechanism 600 .

[0069] For example, the present invention provides a battery production device, comprising: Figures 1 to 3 The burr grinding device for battery pole cutting shown.

[0070] In some implementation scenarios, the burr grinding device for battery pole piece slitting and the battery production equipment provided in the embodiments of the present application can be directly introduced into the deburring tooling after the single cathode piece slitting process, and the battery pole piece cutting edge passing at high speed is ground by the grinding wheel 311 inside the tooling; at the same time, a hollow inverted trumpet-shaped negative pressure dust removal suction cup (first negative pressure suction cup 312) is provided on the outer circle of the grinding wheel 311, and a dust suction mechanism 410 is installed in the forward direction of the battery pole piece grinding to prevent foreign matter that may be splashed and ensure that no new foreign matter is introduced on the battery pole piece. The processed battery pole piece continues to be wound up and other subsequent operations by roller traction, which does not affect the normal production rhythm. The equipment process is simple and no additional operating procedures are required. The processed battery pole piece can greatly reduce the risk of internal short circuit, thereby ensuring product quality and safety; thus, the burr grinding device for battery pole piece slitting and the battery production equipment provided in the embodiments of the present application can solve the problem of battery cell quality and safety caused by burrs generated by cathode piece slitting.

[0071] For example, the battery pole piece slitting burr grinding device and battery production equipment provided in the embodiment of the present application take into account the preparation process of the wound battery cell, and for the purpose of eliminating the burrs on the cathode pole piece slitting edge, directly introduce the deburring device into the pole piece slitting process; Figures 1 to 3 The burr grinding device for battery electrode slitting provided in the embodiment of the present application is described in detail as follows:

[0072] A trumpet-shaped negative pressure suction cup is provided at a certain chamfer on the outside of the grinding disc. This device is connected to the slide rail. At the same time, the distance sensor can measure and determine the distance between the cutting edge of the pole piece and the grinding disc, and adjust the appropriate position under the action of the slide rail. A negative pressure dust removal brush is installed on the large surface in the forward direction of the pole piece. The internal part is a snap-on dust removal brush, which is mainly used to absorb foreign matter that may splash and fall onto the large surface of the pole piece. It is connected to the slide rail through an insert to adjust the up and down or left and right sliding distance from the large surface of the pole piece.

[0073] The distance between the electrode cutting edge and the grinding disc is mainly determined by the distance sensor. The slide rail is adjusted to drive the suction cup to fine-tune the distance and grind the cutting edge. At the same time, the trumpet-shaped negative pressure suction cup on the outer ring of the grinding disc can absorb foreign matter in time. After grinding, the large surface of the electrode moving forward is equipped with a dust suction device. The dust suction disc is equipped with a strip brush with a buckle for easy replacement, which is convenient for absorbing foreign matter that falls on the large surface without affecting the normal winding of the electrode.

[0074] In the embodiment of the present application, the grinding mechanism is placed directly after the trimming process, and is produced according to the process of the preparation process. There is no need to add additional processes to increase the workload, and it does not affect the production rhythm. In addition, the tooling structure of this patent is simple, the preparation cost and process are low, and it can effectively remove the burrs of the electrode without introducing new foreign matter, thereby improving product quality and reducing safety risks.

[0075] In all embodiments of the present application, "big" and "small" are relative, "more" and "less" are relative, and "up" and "down" are relative. The expressions of such relative terms will not be elaborated in the embodiments of the present application.
