When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0031] The battery includes a battery cell and tabs. The battery cell has a positive electrode and a negative electrode. The tabs are metal conductors that lead out the positive and negative electrodes from the battery cell. Generally speaking, they are the contact points when the battery is charged and discharged. To fabricate the tabs, usually in the tab forming process, a metal strip is processed into a tab structure that meets the requirements. The laser cutting device is beneficial to improving the cutting efficiency and quality of the battery tabs, so the laser cutting device for tab cutting has been widely used.

[0032] In the related art, the laser cutting device includes a laser and a guiding component. The guiding component is provided with a guiding channel through which the strip is threaded. One side of the guiding channel is open with a light inlet hole. The laser cuts the strip through the light inlet hole, and the cut strip is further conveyed to the next station through the guiding channel. However, after the laser cuts the strip, there will be many metal residues on the surface of the strip, which affects the processing quality of the strip.

[0033] To solve the above problems, a laser cutting device 10 proposed by the present utility model aims to remove the metal residues remaining on the surface of the strip 28 and ensure the processing quality of the strip 28.

[0034] Refer to Figures 1 to 9, in an embodiment of the present utility model, the laser cutting device 10 includes a frame 1, a guiding assembly 2, a laser 3, and an adsorption assembly 8. The guiding assembly 2 is connected to the frame 1. The guiding assembly 2 is provided with a guiding channel 25 therethrough for the material tape 28 to pass through. One side wall of the guiding channel 25 is provided with a light incident hole 233. The laser 3 is connected to the frame 1 and is used to emit laser light towards the light incident hole 233 to cut the material tape 28. The adsorption assembly 8 includes an adsorbent 83, a conveyor belt 85, a driving wheel 813, and a driving member 811. The adsorbent 83 is connected to the frame 1. The outer surface of the adsorbent 83 facing the material tape 28 is recessed with a negative pressure groove 831. The conveyor belt 85 is sleeved on the outer surface of the adsorbent 83 and is provided with adsorption holes 851 communicating with the negative pressure groove 831. The driving wheel 813 is rotatably connected to the adsorbent 83. The driving member 811 is connected to the adsorbent 83 and is used to drive the driving wheel 813 to rotate. The conveyor belt 85 is driven by the driving wheel 813 to circulate around the outer surface of the adsorbent 83. The conveyor belt 85 performs negative pressure adsorption on the material tape 28 passing out of the guiding channel 25 through the adsorption holes 851.

[0035] Among them, the laser cutting device 10 further includes a first linear module 91, a second linear module 93, and an adjusting assembly 95. The first linear module 91 and the second linear module 93 are used to realize the translation of the laser 3 along the first direction and the second direction. By rotating the adjusting assembly 95, the translation of the laser 3 along the second direction can be realized, so as to adjust the focal position of the laser 3.

[0036] The laser cutting device 10 further includes a material roll assembly and a discharging roller 27. The material roll assembly is used for feeding and transporting the material tape 28, so that the material tape 28 passes through the inlet of the guiding assembly 2. After the material tape 28 is cut by laser at the light incident hole 233 of the guiding assembly 2, it is further discharged from the outlet of the guiding assembly 2 and is discharged through the discharging roller 27.

[0037] Actually, the conveyor belt 85 is integrally sleeved on the outer surface of the adsorbent 83 along the transmission direction. However, it should be noted that the conveyor belt 85 in the drawings is not fully drawn, and only the part of the conveyor belt 85 in contact with the outer surface of the driving wheel 813 is drawn. Correspondingly, the surface of the driving wheel 813 is designed with an appropriate friction coefficient, so as to serve as the contact layer for power transmission with the conveyor belt 85 to ensure that the conveyor belt 85 can be effectively grasped and driven to move. Driven by the driving wheel 813, the conveyor belt 85 can circulate around the outer surface of the adsorbent 83 in the clockwise or counterclockwise direction.

[0038] In the technical solution of the present utility model, the strip 28 passes through the guiding channel 25, and the laser emitted by the laser 3 passes through the light incident hole 233 to cut and process the strip 28 in the guiding channel 25. During the cutting process, there will be a lot of metal waste residues on the surface of the strip 28. At this time, the conveyor belt 85 can use the adsorption holes 851 communicated with the negative pressure groove 831 to perform negative pressure adsorption on the metal waste residues on the surface of the strip 28. Driven by the rotation of the driving wheel 813, the conveyor belt 85 circulates along the outer surface of the adsorbing member 83, so as to timely transfer and carry the adsorbed metal waste residues in a direction away from the negative pressure groove 831, so that the metal waste residues can fall naturally under the action of gravity later. Therefore, more metal waste residues remaining on the surface of the strip 28 are removed, and the efficiency of removing metal waste residues is relatively high, which is beneficial to ensuring the processing quality of the strip 28.

[0039] Referring to Figure 4 and Figure 5 In an embodiment of the present utility model, the adsorbing member 83 includes a first section 833 and a second section 834. The first section 833 is connected to the frame 1, the driving wheel 813 is rotatably connected to the first section 833, and the second section 834 is connected to the first section 833 along an angular direction in the vertical direction.

[0040] In this embodiment, since the second section 834 is connected to the first section 833 along an angular direction in the vertical direction, an inclined slope can be provided, which is beneficial to increasing the conveying stroke of the conveyor belt 85 and ensuring the smooth falling of the metal waste residues, thereby ensuring the normal operation of the adsorption assembly 8.

[0041] Referring to Figure 4 and Figure 5 In an embodiment of the present utility model, the adsorbing member 83 further includes a third section 835, and the third section 835 is connected to the side of the second section 834 away from the first section 833 along the vertical direction.

[0042] In this embodiment, since the third section 835 is connected to the second section 834 along the vertical direction, the rapid falling of the metal waste residues can be realized through the third section 835, and then through the inclined transportation of the second section 834, it is beneficial to reduce the falling time of the waste residues on the surface of the conveyor belt 85, thereby improving the production efficiency.

[0043] Referring to Figure 4 and Figure 5 In an embodiment of the present utility model, the conveyor belt 85 includes a plurality of sub-conveyor belts. The plurality of sub-conveyor belts are respectively sleeved on the outer surface of the adsorbing member 83 and are spaced apart in a direction perpendicular to the moving direction. A gap between two adjacent sub-conveyor belts encloses one of the adsorption holes 851.

[0044] Among them, the sub-conveyor belt can be a round belt or a flat belt.

[0045] In this embodiment, an adsorption hole 851 is formed by enclosing the gap between two adjacent sub-conveyor belts. Compared with a single conveyor belt having multiple adsorption holes, this solution is beneficial to increasing the total area of the multiple adsorption holes 851, improving the total adsorption capacity of the conveyor belt 85, so as to realize the timely transmission of metal waste residues, thereby ensuring the processing quality of the strip 28.

[0046] Optionally, the conveyor belt 85 is provided with a plurality of adsorption holes 851, and the plurality of adsorption holes 851 are arranged at intervals in an array, and the adsorption of metal waste residues is realized through the plurality of adsorption holes 851 arranged in an array.

[0047] Refer to Figure 4 and Figure 5 In an embodiment of the present utility model, the adsorption assembly 8 further includes a negative pressure pipe 86. One end of the negative pressure pipe 86 is communicated with the negative pressure groove 831, and the other end is communicated with an air pump. The number of the negative pressure pipes 86 is provided with a plurality, and the plurality of negative pressure pipes 86 are arranged at intervals along the moving direction of the conveyor belt 85.

[0048] In this embodiment, by providing a plurality of negative pressure pipes 86, the negative pressure in the negative pressure groove 831 is ensured, and then it is beneficial to ensure the sufficient adsorption of the conveyor belt 85 to the metal waste residues, so as to further ensure the processing quality of the strip 28.

[0049] Refer to Figure 4 and Figure 5 In an embodiment of the present utility model, the adsorption assembly 8 further includes a driven wheel 815. The driven wheel 815 and the driving wheel 813 are arranged at intervals along the translation direction of the conveyor belt 85 and are rotatably connected to the adsorbent 83. The driven wheel 815 rotates under the drive of the conveyor belt 85.

[0050] In this embodiment, the driven wheel 815 is used to change the direction of the conveyor belt 85 or provide necessary tension to ensure the stable transportation of the conveyor belt 85 to the metal waste residues, thereby being beneficial to further ensuring the processing quality of the strip 28.

[0051] Refer to Figure 4 and Figure 5 In an embodiment of the present utility model, the adsorption assembly 8 further includes two second connectors 816 and a tensioning wheel 817. The two second connectors 816 are connected to opposite sides of the adsorbent 83 and are movably arranged along a direction perpendicular to the moving direction of the conveyor belt 85. Opposite sides of the tensioning wheel 817 are rotatably connected to the two second connectors 816. The tensioning wheel 817 abuts against the conveyor belt 85 and rotates under the drive of the conveyor belt 85.

[0052] Among them, in an embodiment where the second connecting member 816 is movably arranged, a third sliding groove 8161 is formed on one side of the second connecting member 816. The third sliding groove 8161 extends in a direction perpendicular to the moving direction of the conveyor belt 85. A third positioning hole 836 is formed on one side of the adsorbing member 83. The third positioning hole 836 is connected with a fastening member, and the fastening member passes through the third sliding groove 8161, thereby realizing the movable arrangement of the second connecting member 816.

[0053] In this embodiment, the tensioning wheel 817 is used to adjust the tension of the conveyor belt 85, ensuring that the conveyor belt 85 maintains an appropriate pressure between the driving wheel 813 and the driven wheel 815 to prevent the strip 28 from slipping, thereby further ensuring the stable transportation of the metal waste residue by the conveyor belt 85.

[0054] Refer to Figure 1 、 Figure 2 and Figure 9 In an embodiment of the present utility model, the laser cutting device 10 further includes a waste collection assembly 6. The waste collection assembly 6 includes a bin body 61 and a first negative pressure assembly 63. The bin body 61 is arranged vertically below the guiding assembly 2. The bin body 61 is provided with a collection hole 611. One side of the collection hole 611 facing away from the guiding assembly 2 is communicated with the first negative pressure assembly 63, and the first negative pressure assembly 63 is used for negative pressure adsorption of the collection hole 611.

[0055] Among them, the first negative pressure assembly 63 includes a first negative pressure pipe and an air pump. One end of the first negative pressure pipe is communicated with the collection hole 611, and the other end is communicated with the air pump.

[0056] In this embodiment, after the laser 3 cuts the strip 28, a lot of charged dust is generated. After these charged dusts are neutralized electrically by the first ion generator 4, they fall down due to the action of gravity. The collection hole 611 of the bin body 61 can be used to cache the falling charged dust, and finally the first negative pressure assembly 63 completes the final adsorption and collection of the dust in the collection hole 611 to ensure that the dust in the collection hole 611 is timely evacuated, which is beneficial to the continuous operation of the laser cutting device 10.

[0057] It should be noted that the size of the collection hole 611 of the bin body 61 is large enough and can be set to twice the length and width of the guiding assembly 2, so that the falling charged dust can directly fall into the collection hole 611 of the bin body 61, avoiding adjusting the position of the bin body 61 and reducing the processing steps.

[0058] Refer to Figure 1 and Figure 2, in an embodiment of the present utility model, the laser cutting device 10 further includes a second negative pressure assembly 73, and the second negative pressure assembly 73 is communicated with the light incident hole 233 for performing negative pressure adsorption on the light incident hole 233.

[0059] Among them, the second negative pressure assembly 73 includes a second negative pressure pipe and an air pump. One end of the second negative pressure pipe is communicated with the light incident hole 233, and the other end is communicated with the air pump.

[0060] In this embodiment, when the laser cuts the strip 28 through the light incident hole 233, due to the sharp photothermal effect, a lot of dust will also be generated in the light incident hole 233. By sucking the dust in the light incident hole 233 through the second negative pressure assembly 73, it is beneficial to ensure the normal cutting of the strip 28 by the laser, thereby further improving the processing quality of the strip 28.

[0061] Refer to Figure 3 、 Figure 6 and Figure 7 , in an embodiment of the present utility model, the guiding assembly 2 includes a first guiding member 21 and a second guiding member 23.

[0062] Among them, the guiding assembly 2 further includes a telescopic member 26. The telescopic member 26 is connected to the frame 1, and the second guiding member 23 is connected to the telescopic end of the telescopic member 26, so as to realize the movable arrangement along a direction close to or away from the first guiding member 21.

[0063] A first guide roller 211 is provided on the side of the first guiding member 21 facing the second guiding member 23, and a second guide roller 231 is provided on the side of the second guiding member 23 facing the first guiding member 21. The transmission of the strip 28 by the first guide roller 211 and the second guide roller 231 can play a role in clamping, supporting and guiding, ensuring the stable transmission of the strip 28 and the quality of laser cutting.

[0064] The first guiding member 21 is provided with a light outlet hole 213 communicated with the light incident hole 233. After the laser passes through the light incident hole 233, it further hits the light blocking member 215. The light blocking member 215 is provided with a heat dissipation fin structure for absorbing the laser, so as to ensure production safety.

[0065] In this embodiment, when the second guiding member 23 is in a position far from the first guiding member 21, it is convenient to thread the strip 28 between the first guiding member 21 and the second guiding member 23. After the strip 28 is threaded, the second guiding member 23 moves towards the first guiding member 21 and finally encloses with the first guiding member 21 to form a guiding channel 25 that provides guiding support for the strip 28, so as to ensure the cutting process of the strip 28 by the laser 3. Therefore, by movably arranging the second guiding member 23 along the direction close to or away from the first guiding member 21, it is convenient to place the strip 28, which is beneficial to improving production efficiency.

[0066] Referring to Figures 1 to 9 , in an embodiment of the present utility model, the laser cutting device 10 further includes a first ion generator 4, and the first ion generator 4 is arranged on one side of the guiding assembly 2 for blowing out ion wind to electrically neutralize the charged dust generated by the cutting of the strip 28.

During the cutting process, charged dust will be generated around the strip 28. At this time, the ion wind emitted by the first ion generator 4 can electrically neutralize these charged dust, remove the charge of the charged dust, and thus avoid the charged dust from adsorbing on the strip 28, which is beneficial to ensuring the processing quality of the strip 28.

[0077] In this embodiment, through the cooperation between the second sliding groove 531 and the second sliding portion, it is convenient to adjust the position of the first ion generator 4 in the horizontal direction, which is conducive to quickly adjusting the blowing position of the first ion generator 4 in the horizontal direction.

[0078] Optionally, a second positioning hole 235 is formed on the first connecting plate 51. A fastening member is inserted through the second positioning hole 235, and one side of the inserted fastening member facing the second sliding groove 531 serves as the second sliding portion.

[0079] Refer to Figure 3, in an embodiment of the present utility model, there are two first ion generators 4, and the two first ion generators 4 are arranged on opposite sides of the tape 28. The ion rod of one first ion generator 4 extends upward in the vertical direction, and the ion rod of the other first ion generator 4 extends downward in the vertical direction.

[0080] In this embodiment, when the ion rod extends upward in the vertical direction, it can achieve the electrical neutralization of the floating dust at high places. When the ion rod extends downward in the vertical direction, it can achieve the electrical neutralization of the suspended dust at low places. Through the setting of one high and one low, it is beneficial to ensure the electrical neutralization of the charged dust in each area, so as to further improve the dust removal rate.

[0081] Refer to Figure 3 , in an embodiment of the present utility model, the laser 3 includes a light-emitting housing 31, a field lens 33, and a second ion generator 35. The light-emitting housing 31 is connected to the frame 1, the field lens 33 is connected to the light-emitting side of the light-emitting housing 31, and the second ion generator 35 is arranged on the periphery of the field lens 33 to blow ion wind to the light-emitting side of the field lens 33.

[0082] Among them, the second ion generator 35 can be selected as an ion air knife.

[0083] In this embodiment, the laser 3 emits light through the field lens 33 to achieve laser cutting of the tape 28. By blowing ion wind to the periphery of the field lens 33 through the second ion generator 35, the charged dust around the field lens 33 can be electrically neutralized, thereby preventing the charged dust from adhering to the surface of the field lens 33, which is beneficial to protecting the field lens 33 and ensuring the processing quality of the laser 3.
