Description

Technical Field

[0002] Battery pole piece cutting is one of the important processes in battery production and processing. Usually, the pole piece strip is transferred to the cutting platform of the pole piece cutting equipment, and then the cutting mechanism cuts the pole piece strip to obtain the required pole piece. Waste will be generated during the pole piece cutting process, and dust will be generated at the cutting part of the pole piece. If the dust and waste are not removed in time, the accumulation of dust and waste will affect the cutting accuracy of the pole piece.

[0003] An existing pole piece cutting device is provided with a dust hood, and a cutting platform is arranged in the dust hood. The pole piece cutting operation is carried out in the dust hood, and the dust hood absorbs dust, thereby achieving the purpose of removing dust. However, when cutting the pole piece, dust will be generated above and below the cutting part of the pole piece. The dust hood can only absorb the dust above the pole piece, while the dust below the pole piece is difficult to be absorbed and removed by the dust hood, and the dust below the pole piece will still accumulate. In addition, the dust hood cannot remove large waste materials, and the waste generated by the pole piece cutting will also accumulate, thereby affecting the cutting accuracy of the pole piece.

[0055] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0056] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0057] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0058] In the description of the present invention, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0059] like Figure 1 As shown, this embodiment provides a pole piece cutting platform, which includes a platform body 1, a first negative pressure collection mechanism 2 and a second negative pressure collection mechanism 3. Figure 2 As shown, a cutting position 11 is provided on the platform body 1, and the cutting position 11 is suitable for placing the electrode sheet. The sides of the cutting position 11 along the first direction and the second direction are formed with slits 12, and a waste outlet 13 is provided on the side of the platform body 1 near the cutting position 11 along the second direction. The first negative pressure collection mechanism 2 is provided at the bottom of the platform body 1, and the first negative pressure collection mechanism 2 is connected with the slit 12 and / or the waste outlet 13. The second negative pressure collection mechanism 3 is provided on the upper surface of the platform body 1 and is located on the side of the platform body 1 along the second direction.

[0060] When the electrode material strip is cut corresponding to the slit 12, dust will be generated above and below the electrode cutting part. The dust below the electrode cutting part is collected by the first negative pressure collection mechanism 2 through the slit 12, and the dust above the electrode cutting part is collected by the second negative pressure collection mechanism 3. The waste generated when the electrode is cut is collected by the first negative pressure collection mechanism 2 through the waste outlet 13. Therefore, the electrode cutting platform of this embodiment can remove and collect the dust generated above and below the electrode cutting part at the same time, and can also remove and collect the waste in time, thereby effectively preventing the accumulation of dust and waste at the electrode cutting part, and ensuring the cutting accuracy of the electrode.

[0061] Furthermore, the first negative pressure collection mechanism 2 includes a first dust hood 21, an opening of the first dust hood 21 is provided at the slit 12, a first negative pressure pipeline 22 is provided at the bottom of the first dust hood 21, and the first negative pressure pipeline 22 is suitable for connecting with an external negative pressure mechanism. The external negative pressure mechanism can generate negative pressure in the first dust hood 21, and then the dust generated at the electrode cutting part can be sucked into the first dust hood 21 through the slit 12, so that the dust removal effect is better and the dust is effectively prevented from accumulating at the bottom of the electrode.

[0062] Furthermore, if Figure 1 and Figure 3As shown, the first negative pressure collection mechanism 2 further includes a waste collection cover 23, the opening of which is disposed at the waste outlet 13, and a second negative pressure pipeline 24 is disposed on the waste collection cover 23, and the second negative pressure pipeline 24 is suitable for connecting with an external negative pressure mechanism. The external negative pressure mechanism can generate negative pressure in the waste collection cover 23, and the waste generated by the electrode cutting is sucked into the waste collection cover 23 through the waste outlet 13, so that the waste removal effect is better.

[0063] Furthermore, the first negative pressure collection mechanism 2 of the present embodiment further includes a cake press and a waste discharge pipe (not shown in the figure), one end of the waste discharge pipe is connected to the bottom of the waste collection cover 23, and the other end of the waste discharge pipe is arranged corresponding to the feeding end of the cake press. The second negative pressure pipeline 24 generates negative pressure in the waste collection cover 23 to suck the waste into the waste collection cover 23, and the waste is discharged to the feeding end of the cake press through the waste discharge port 13, the waste collection cover 23 and the waste discharge pipe in turn, and then the cake press compresses the waste so that the waste can be better collected and stored.

[0064] Furthermore, if Figure 2 As shown, there are multiple cutting positions 11, and the multiple cutting positions 11 are arranged at intervals along the first direction, and preferably at equal intervals. The cutting position 11 includes a pole ear portion 111, and the gap between adjacent cutting positions 11 forms a slit 12 to facilitate the cutting operation of the pole piece. The pole ear is formed by cutting the empty foil area on the pole piece strip. Therefore, in the process of cutting the pole ear of the pole piece strip, the foil between the pole ear portions 111 of adjacent cutting positions 11 will form waste. Therefore, the waste outlet 13 is arranged between the pole ear portions 111 of adjacent cutting positions 11, so that the waste is discharged and collected by the waste outlet 13. Among them, the first negative pressure collection mechanism 2 is connected to the multiple slits 12 and / or the multiple waste outlets 13 to realize the complete collection of dust and waste. This solution can make the cutting operation more efficient and accurate by setting multiple cutting positions 11 on the platform body 1 to cut the pole piece, while better ensuring the removal effect of dust and waste.

[0065] Preferably, the pole piece strip on one side of the pole lug covers a portion of the waste outlet 13 , so that the generated waste can be more easily collected into the waste collecting cover 23 .

[0066] Furthermore, if Figures 4 to 8 As shown, the second negative pressure collection mechanism 3 includes a second dust hood 31 and a wind knife 32. The second dust hood 31 and the wind knife 32 are respectively arranged on both sides of the platform body 1 along the second direction. The opening of the second dust hood 31 faces the wind knife 32. The wind knife 32 supplies air toward the second dust hood 31 to blow the dust generated above the pole piece cutting part into the second dust hood 31, and then clear and collect the dust generated above the pole piece cutting part, so as to further improve the dust removal effect.

[0067] Furthermore, there are multiple cutting positions 11, which are spaced apart along the first direction. In order to ensure that the effective dust removal range of the second dust hood 31 and the wind knife 32 covers all the cutting positions of the electrode strip, so that the second negative pressure collection mechanism 3 has a better dust removal effect, the opening of the second dust hood 31 is long and extends along the first direction, and there are multiple wind knives 32, which are spaced apart along the first direction.

[0068] For the second dust hood 31 and the wind knife 32, this embodiment also provides another technical solution, that is, the second dust hood 31 is provided with multiple wind knives 32 in the first direction, and the wind knives 32 are slidably arranged in the first direction. The wind knife 32 moves with the change of the cutting part of the pole piece, that is, the wind knife 32 is always aimed at the cutting point on the pole piece, and then the dust is blown into the second dust hood 31, thereby achieving the effect of accurately removing dust, and there is no need to open multiple wind knives 32 at the same time, saving electricity and occupying space.

[0069] Preferably, the second dust hood 31 is connected to an external negative pressure mechanism through a pipe, and the external negative pressure mechanism can generate negative pressure in the second dust hood 31, so that the second dust hood 31 can absorb dust, and then cooperate with the wind knife 32 to blow the dust to the second dust hood 31, thereby further improving the dust removal effect.

[0070] Furthermore, if Fig. 9 As shown, the electrode cutting platform of this embodiment also includes a third negative pressure pipeline 4, a plurality of adsorption holes 112 are provided on the cutting position 11, a negative pressure chamber 14 is provided on the inner side of the cutting position 11, the adsorption holes 112 are connected to the negative pressure chamber 14, one end of the third negative pressure pipeline 4 is connected to the negative pressure chamber 14, and the other end of the third negative pressure pipeline 4 is connected to the external negative pressure mechanism. When performing the electrode cutting operation, the electrode is easily deflected under the action of the cutting force and the influence of the wind knife 32. The external negative pressure mechanism of this embodiment can generate negative pressure in the negative pressure chamber 14, thereby realizing that the plurality of adsorption holes 112 adsorb the electrode to ensure the stability of the electrode, thereby ensuring the cutting accuracy of the electrode.

[0071] Preferably, the distribution density of the adsorption holes 112 at the pole ear portion 111 on the cutting position 11 is greater than the distribution density of the adsorption holes 112 at other positions on the cutting position 11, so that the adsorption force of the adsorption holes 112 at the pole ear portion 111 is greater, thereby ensuring that the pole ear cutting operation of the pole piece is more stable, thereby ensuring the cutting accuracy of the pole ear.

[0072] Preferably, the external negative pressure mechanism is a dust collector, and the existing dust collectors on the market have both adsorption and storage functions. The dust collector can not only suck air to generate negative pressure in the first dust hood 21, the second dust hood 31, the waste hood 23 and the negative pressure chamber 14, but also suck the dust in the first dust hood 21 and the second dust hood 31 into the dust collector for storage.

[0073] In this embodiment, during the cutting process of the pole piece and the preparation stage before and after the cutting process, the negative pressure mechanism is always kept in an open state to achieve a better dust removal effect.

[0074] Preferably, the first dust hood 21, the second dust hood 31, the waste collection hood 23 and the negative pressure chamber 14 are all connected to the same negative pressure mechanism to facilitate the control of the negative pressure mechanism. There is no need to set up multiple negative pressure mechanisms to reduce the start and stop operations of the negative pressure mechanism and improve production efficiency.

[0075] Furthermore, the electrode piece needs to be removed after cutting is completed, in order to reduce the adsorption force of the adsorption hole 112 on the electrode piece, so as to facilitate the picking up of the electrode piece. A positive pressure port 15 is provided in the negative pressure chamber 14 of this embodiment, and the positive pressure port 15 is suitable for introducing positive pressure into the negative pressure chamber 14, thereby reducing the force of the negative pressure in the negative pressure chamber 14, thereby reducing the adsorption force of the adsorption hole 112 on the electrode piece. When the positive pressure port 15 does not introduce positive pressure into the negative pressure chamber 14, the force recovery of the negative pressure in the negative pressure chamber 14 increases, thereby completing the adsorption of the electrode piece by the adsorption hole 112 during the next round of electrode piece cutting operation.

[0076] Specifically, the positive pressure port 15 is a positive pressure fan, the output end of the positive pressure fan is installed and connected to the negative pressure chamber 14, the positive pressure fan can send air into the negative pressure chamber 14 to reduce the force of the negative pressure in the negative pressure chamber 14, and the positive pressure fan can also stop sending air into the negative pressure chamber 14 to restore the force of the negative pressure in the negative pressure chamber 14. Those skilled in the art can set the positive pressure fan so that the positive pressure fan can automatically start or stop sending air, thereby improving production efficiency.

The platform body 1 is arranged on the fixing platform 5, and the cutting structure 6 is located above the fixing platform 5. The cutting structure 6 is used to cut the pole piece strip.

[0079] Further, the platform body 1 is slidably disposed on the fixed platform 5 and is suitable for carrying the pole piece strip. The pole piece strip and the platform body 1 slide synchronously relative to the fixed platform 5. The platform body 1 has a first position and a second position on the fixed platform 5. When the platform body 1 is in the first position, please refer to Fig.10 and Fig.11 , when the platform body 1 is in the second position, please refer to Fig.12 and Fig.13, the cutting structure 6 is fixedly arranged above the fixing platform 5. In the process of the platform body 1 moving from the first position to the second position, the platform body 1 drives the pole piece strip to pass through the cutting structure 6, and the cutting structure 6 cuts the pole piece strip into a plurality of pole pieces. This solution does not require the cutting structure 6 to move for cutting, which can make the overall production efficiency faster.

[0080] Furthermore, the cutting structure 6 of the first embodiment has another implementation mode, that is, the cutting structure 6 is movably arranged above the fixing platform 5 along the extension direction of the fixing platform 5. After the platform body 1 moves from the first position to the second position, the cutting structure 6 moves above the pole piece strip and cuts the pole piece strip into a plurality of pole pieces.

[0081] Furthermore, the cutting structure 6 includes a laser, which moves above the pole piece strip and emits laser to cut the pole piece strip. The laser cutting method can make the cutting accuracy and cutting efficiency higher.

[0083] The structures of the pole piece cutting equipment of the second embodiment are basically the same as those of the first embodiment, except that the platform body 1 of the second embodiment is fixedly arranged on the fixing platform 5 .

[0084] Specifically, if Fig.14 As shown, the platform body 1 is fixedly arranged on the fixed platform 5 and is suitable for carrying the pole piece strip, and the cutting structure 6 is movably arranged above the fixed platform 5 along the extension direction of the fixed platform 5, and the cutting structure 6 moves above the pole piece strip and cuts the pole piece strip into a plurality of pole pieces. The platform body 1 is large in volume and requires more moving space, so that the space occupied by the pole piece cutting device is large, while the platform body 1 of this solution does not move, and the relatively small cutting structure 6 moves and cuts, thereby greatly saving the space occupied by the pole piece making device.

[0085] Specifically, Fig.15 As shown, the cutting structure 6 has a first position on the fixing table 5; Fig.16 As shown, the cutting structure 6 has a second position on the fixing table 5, and the cutting structure 6 moves between the first position and the second position to cut the pole piece strip.

[0086] It should be noted that Fig.14 Two cutting structures 6 are shown, which schematically illustrate two extreme positions of a cutting structure 6 during the cutting process. Fig.14 The content shown should not be understood as two cutting structures 6 being provided on the fixing table 5 .
