[0045] In the description of the utility model, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0046] When laser cutting the pole piece material, a large amount of smoke, exhaust gas and other pollutants are generated on the front and back sides of the pole piece material being cut. The pollutants may fall onto the pole piece material being cut, affecting the quality of the pole piece after cutting, or enter the device for cutting the pole piece, contaminating the precision structure, or spread in the production environment, causing safety hazards. For this reason, it is necessary to promptly and comprehensively deal with the pollutants generated during laser cutting to reduce the above-mentioned impact. At the same time, when the pole piece material is cut by laser to obtain the pole piece and pole piece waste of the required specifications, the pole piece needs to be transported in time to enter the next production process, and the pole piece waste needs to be recycled in time to avoid interfering with the subsequent cutting process.

[0047] Reference Figures 1 to 7The dust removal device 100 of the first embodiment of the utility model includes a carrier 110, a first dust removal mechanism 120 and a second dust removal mechanism 130. The carrier 110 has a first side 111 and a second side 112 that are separated from each other. The carrier 110 includes a first carrier 113 and a second carrier 114. The first carrier 113 is arranged around the outer peripheral side of the second carrier 114 and has a first gap 115 between the second carrier 114 to reduce mutual interference. The first carrier 113 and the second carrier 114 are located on the surface of the first side 111 for carrying the electrode material to be cut. The second carrier 114 includes a bearing portion 1141 for carrying the electrode obtained after cutting. The first gap 115 is used to avoid laser and provide a laser cutting path to improve the laser cutting efficiency and the quality of the electrode after cutting. The first dust removal mechanism 120 is arranged on the second On the peripheral side of the carrier 114, the first dust removal mechanism 120 has a dust removal port 121, and the dust removal port 121 faces above the first side 111 of the carrier 110, and is used to remove dust from the first side 111 of the carrier 110, so that during laser cutting, the surface and the peripheral side of the pole piece material located on the first side 111 can be dusted; the second dust removal mechanism 130 is arranged on the second side 112 of the carrier 110, and the interior of the second dust removal mechanism 130 is provided with a dust removal channel 131, and the dust removal channel 131 is connected to the first gap 115. The dust removal channel 131 is suitable for connecting to a negative pressure air source to remove dust from the second side 112 of the carrier 110, which helps to adsorb the pole piece material at the second carrier 114 position to prevent relative displacement, resulting in cutting path errors, and affecting the quality of the pole piece after cutting. At the same time, pollutants such as smoke and exhaust gas generated when the laser is cut along the first gap 115 are sucked.

[0048] When the dust removal device 100 is in use, the electrode material is transported to the first side 111 of the carrier 110 and is located at the second carrier 114, and the dust removal channel 131 is connected to the negative pressure gas source. The dust removal port 121 of the first dust removal mechanism 120 draws gas toward the top of the first side 111 of the carrier 110, and the second dust removal mechanism 130 on the second side 112 of the carrier 110 draws gas through the first gap 115 connected to the dust removal channel 131. When the laser is emitted from above the carrier 110 and the pole piece material is cut along the path of the first gap 115, the dust removal port 121 of the first dust removal mechanism 120 sucks pollutants on the surface and the outer periphery of the pole piece material located on the first side 111, and the second dust removal mechanism 130 sucks pollutants on the pole piece material relative to the first gap 115, or pollutants on the second side 112 of the carrier 110, so that during cutting, pollutants on the surface of the first side 111, the surface of the second side 112, and the outer periphery of the pole piece material can be absorbed, thereby reducing pollutants during the cutting process, reducing the pollution of pollutants to the pole piece material and the cutting equipment, ensuring cutting accuracy, improving the quality of the pole piece after cutting, and reducing pollution to the surrounding environment. The pollution of the above-mentioned cutting equipment includes smoke pollutants generated by cutting, and the dust removal device 100 can effectively prevent these pollutants from entering the precision structure of the cutting equipment, causing damage to the cutting equipment, and affecting the cutting accuracy.

[0049] It should be noted that when the first dust removal mechanism 120 and the second dust removal mechanism 130 are started, the dust removal port 121 of the first dust removal mechanism 120 draws gas toward the top of the first side 111 of the carrier 110, which can avoid the adsorption force generated by the negative pressure at the dust removal port 121 during suction affecting the stable placement of the electrode material. At the same time, the second dust removal mechanism 130 is arranged on the second side 112 of the carrier 110, and is provided with a dust removal channel 131 connected to the first gap 115. It can not only draw pollutants generated by laser cutting of the electrode material from the first gap 115, but also adsorb the electrode material to avoid displacement of the electrode material relative to the second carrier 114, resulting in errors in the laser cutting path and affecting the quality of the electrode after cutting. Furthermore, the electrode after cutting can be adsorbed on the carrier 1141, which helps the transfer device to grab the cut electrode relative to the carrier 1141 when the electrode is subsequently transferred, thereby improving the efficiency and accuracy of the transfer.

[0050] In addition, the first carrier 113 is arranged on the outer peripheral side of the second carrier 114 and has a first gap 115 between the first carrier 113 and the second carrier 114, so that the first carrier 113 is separated from the second carrier 114, thereby preventing the first carrier 113 from shaking during the operation of the dust removal device 100 and affecting the stability of the second carrier 114, thereby ensuring the stability of the second carrier 114 when laser cutting the pole piece material and improving the cutting quality.

[0051] As an improvement of the above embodiment, the size of the bearing portion 1141 and the position of the first gap 115 between the corresponding first bearing member 113 and the second bearing member 114 can be adjusted according to actual production requirements to adapt to pole pieces of different specifications, thereby expanding the scope of application of the dust removal device 100.

[0052] Reference Figures 2 to 6 In the dust removal device 100 of the embodiment of the utility model, the second carrier 114 includes at least two carriers 1141, a partition 1142 is provided between adjacent carriers 1141, the partition 1142 is connected to the first carrier 113, a second gap 116 is provided between the carrier 1141 and the partition 1142, the second gap 116 is communicated with the first gap 115, and is used to avoid laser, and the dust removal channel 131 is communicated with the second gap 116. When the dust removal device 100 is used, the pole piece material is transported to the second carrier 114 on the first side 111 of the stage, the partition 1142 divides each bearing part 1141, so as to distinguish adjacent bearing parts 1141 and avoid interference caused by cutting, each bearing part 1141 corresponds to a part of the pole piece material, so as to obtain multiple pole pieces of required specifications after cutting, the laser can be emitted from directly above the stage 110, and cutting is performed around the bearing part 1141 along the first gap 115 and the second gap 116, and the cutting path is accurate, thereby ensuring that the pole piece specifications obtained after cutting are qualified. At the same time, during the cutting process, the dust removal port 121 of the first dust removal mechanism 120 draws gas toward the top of the first side 111 of the carrier 110 to remove pollutants on the surface and peripheral side of the electrode material on the first side 111. The second dust removal mechanism 130 on the second side 112 of the carrier 110 draws pollutants from the electrode material relative to the first gap 115 and the second gap 116, or pollutants on the second side 112 of the carrier 110, to remove pollutants on the cutting path and on the second side 112 of the carrier 110, thereby reducing pollutants around the electrode material, reducing pollution to the electrode material, cutting equipment and the surrounding environment, and further ensuring cutting accuracy and the quality of the electrode after cutting, while reducing safety hazards.

[0053] It should be noted that the number of the bearing parts 1141 can be set according to production requirements. When four bearing parts 1141 are provided, a partition 1142 is provided between adjacent bearing parts 1141, the partition 1142 is connected to the first bearing member 113, and a second gap 116 is provided between the bearing part 1141 and the partition 1142, and the second gap 116 is connected to the first gap 115 for avoiding laser, and the dust removal channel 131 is connected to the second gap 116, so that two laser devices are provided correspondingly, and can correspond to different bearing parts 1141 at the same time, and cut along the first gap 115 and the second gap 116 surrounding the outer periphery of the corresponding bearing part 1141, respectively, so as to realize a one-time cutting process, obtain multiple required pole pieces, and improve production efficiency.

[0054] The number of carriers 1141 and the number of laser devices may also be set according to production requirements or equipment layout requirements, wherein, in one cutting process, one laser device performs cutting around one carrier 1141 to obtain one required pole piece. For example, when the number of carriers 1141 is greater than the number of laser devices, the pole piece material is located on the second carrier 114, and each carrier 1141 corresponds to a different part of the pole piece material, the laser device emits a laser to cut the pole piece material around the carrier 1141 along the first gap 115 and the second gap 116. When the one-time cutting process is completed, the required pole pieces corresponding to the number of laser devices are obtained. Multiple operations are required until the pole piece materials corresponding to each carrier 1141 are cut, and the cut pole pieces and pole piece waste are obtained. In some other embodiments, the number of carriers 1141 is equal to the number of laser devices, and when the one-time cutting process is completed, the required pole pieces corresponding to the number of carriers 1141 are obtained without the need for secondary operations, thereby improving production efficiency.

It should be noted that a number of through holes 117 can be provided according to production needs to achieve the above-mentioned effects.

[0057] In some other embodiments, a through hole 117 is provided on the bearing portion 1141 and the first bearing member 113, and the through hole 117 is connected to the dust removal channel 131 of the second dust removal mechanism 130.

The through hole 117 located on the support part 1141 can absorb the electrode material located on the support part 1141 or the electrode obtained after cutting, so as to avoid the suction force of the first dust removal mechanism 120 during the suction and dust removal causing the electrode material to move relative to the second support part 114, thus affecting the cutting quality. At the same time, it helps when the electrode is subsequently transferred, the transfer device grabs the electrode relative to the support part 1141, thereby improving the efficiency and accuracy of the transfer.

When the dust removal device 100 is in use, the electrode material is transported to the first side 111 of the carrier 110, and the part to be cut is located at the second carrier 114. When the laser is emitted from above the carrier 110 and cuts the electrode material along the path of the first gap 115, the dust removal port 121 at the edge portion 1221 around the outer side of the first gap 115 can quickly and effectively remove the pollutants generated by the cutting. At the same time, the first dust removal cover 122 can ensure that when the pollutants are sucked out, they do not overflow to cause secondary pollution.

[0063] Reference Figures 1 to 4 In the dust removal device 100 of the embodiment of the utility model, the first dust removal cover 122 is provided with a contoured notch 1222. Along the direction perpendicular to the first carrier 113, the contoured notch 1222 corresponds to the pole ear portion 1144. The contoured notch 1222 is formed by being recessed inward from the edge portion 1221. The projection of the side wall of the contoured notch 1222 on the first carrier 113 is located around the outer side of the second portion 1152.

When the electrode material is cut along the first part 1151 and the second part 1152 of the first gap 115, the contoured notch 1222 can avoid the laser path and can comprehensively and quickly remove the dust from the pollutants generated on the cutting path. The dust removal channel 131 can remove the dust from the second side 112 of the carrier 110 and the first gap 115 to ensure that the pollutants will not contaminate the electrode material, the cutting equipment and the surrounding environment, thereby improving the cutting quality and reducing production safety hazards.

The first dust removal chamber 123 is connected to the negative pressure gas source, and its edge portion 1221 and the profiling notch 1222 form a dust removal port 121 to suck gas toward the first side 111 of the carrier 110. When the laser is emitted from above the carrier 110 and cuts the electrode material along the first part 1151 and the second part 1152, the dust removal port 121 can accurately remove dust from the pollutants at the first part 1151 and the second part 1152, and the second dust removal mechanism 130 removes dust from the second side 112, thereby improving the dust removal efficiency, reducing pollutants generated by cutting, and further improving the cutting quality.

When in use, the electrode material is located at the second carrier 114, the dust removal channel 131 is connected to the negative pressure gas source, the first dust removal chamber 123 is connected to the negative pressure gas source, and its edge portion 1221 and the contoured notch 1222 form a dust removal port 121 to draw gas toward the first side 111 of the carrier 110. When the laser is emitted from above the carrier 110 and cuts the electrode material along the first gap 115, the dust removal hoods respectively arranged on the first peripheral side, the second peripheral side, the third peripheral side and the fourth peripheral side of the second carrier 114 can remove dust from four directions on the pollutants generated at the second carrier 114 during the cutting process, thereby improving the dust removal efficiency, reducing the impact of pollutants on the electrode material, cutting equipment and the surrounding environment, and improving the cutting quality and the electrode quality.

[0066] Reference Figure 1 , Figures 3 to 8The dust removal device 100 of the embodiment of the utility model, the first dust removal mechanism 120 includes a first dust removal cover 122 and a wind knife 124, the first dust removal cover 122 and the wind knife 124 are arranged on both sides of the carrier 110 facing each other along a first direction, the first direction is perpendicular to the normal of the surface of the second carrier 114 located on the first side 111, wherein: the first dust removal cover 122 has a first dust removal cavity 123 inside, the first dust removal cover 122 is provided with a dust removal port 121 above the first side 111 of the carrier 110, the dust removal port 121 is connected to the first dust removal cavity 123, and the first dust removal cavity 123 is suitable for connecting to a negative pressure air source to remove dust from the first side 111 of the carrier 110; the wind knife 124 has an air outlet 1241, and the air outlet 1241 is located on the opposite side of the dust removal port 121. When the dust removal device 100 is in use, the electrode material is located at the second carrier 114, the first dust removal mechanism 120 is started, and the first dust removal chamber 123 is suitable for connecting to a negative pressure gas source to draw gas toward the dust removal port 121 above the first side 111 of the carrier 110, and the air outlet 1241 of the wind knife 124 blows air toward the dust removal port 121. When the laser is emitted from above the carrier 110 and the electrode material is cut along the first gap 115, the air outlet 1241 blows air along the first direction to blow the pollutants generated by the second carrier 114 toward the dust removal port 121, and the dust removal port 121 draws the pollutants for dust removal, so that the pollutants generated during cutting are quickly sucked into the first dust removal chamber 123 by the dust removal port 121, thereby reducing cutting pollutants, improving cutting quality and reducing pollution to the surrounding environment.

[0067] It should be noted that the first dust removal cover 122 is provided with a dust removal port 121 above the first side 111 of the carrier 110, and the dust removal port 121 is connected to the first dust removal chamber 123, which can not only ensure the dust removal efficiency of the first side 111 of the carrier 110, but also reduce the suction of the dust removal port 121 on the electrode material, thereby ensuring the cutting quality.

[0068] Reference Figure 1 , Figure 4 and Figure 5 In the dust removal device 100 of the embodiment of the utility model, the size of the dust removal port 121 along the second direction is greater than the size of the second carrier 114, the second direction is perpendicular to the first direction, and the second direction is perpendicular to the normal direction. When the dust removal device 100 is in use, the pole piece material is located at the second carrier 114, and the laser is emitted from above the carrier 110. During the cutting process of the pole piece material along the first gap 115, the dust removal range of the dust removal port 121 along the first direction can cover the second carrier 114, which is conducive to fully absorbing the pollutants generated by the cutting, avoiding the dust removal range being too small, resulting in insufficient dust removal force, and pollutants overflowing, causing pollution to the pole piece material and the surrounding environment.

[0069] Reference Figure 1 , Figures 4 to 8In the dust removal device 100 of the embodiment of the utility model, there is a height difference between the air outlet 1241 and the second carrier 114 along the normal direction of the surface of the second carrier 114 located on the first side 111, and the size of the dust removal port 121 is larger than the size of the air outlet 1241; the air outlet 1241 is toward the top of the first side 111 of the second carrier 114. When the dust removal device 100 is in use, the electrode material is located at the second carrier 114, and the laser is emitted from above the carrier 110. During the cutting process of the electrode material along the first gap 115, the height difference between the air outlet 1241 and the second carrier 114 can prevent the electrode material from moving relative to the second carrier 114 when the air outlet 1241 blows air along the first direction, thereby affecting the subsequent cutting. At the same time, the size of the dust removal port 121 is larger than the size of the air outlet 1241, so that the pollutants blown from the air outlet 1241 to the dust removal port 121 are absorbed by the dust removal port 121 without overflowing, thereby ensuring the dust removal efficiency, and further reducing the pollutants generated by the cutting and improving the cutting quality.

In addition, the adjustment components 140 respectively arranged along the first direction and the second direction can adjust the position of the air outlet 1241 relative to the dust removal port 121, so that the blowing path direction of the air outlet 1241 is consistent with the dust removal direction of the dust removal port 121, thereby ensuring the dust removal efficiency.
