[0031] The battery includes a battery cell and an electrode tab. The battery cell has a positive electrode and a negative electrode. The electrode tab is a metal conductor that leads out the positive and negative electrodes from the battery cell. Generally speaking, it is the contact point when the battery is charged and discharged. To realize the preparation of the electrode tab, usually in the electrode tab forming and processing process, the metal strip is processed into an electrode tab structure that meets the requirements. The laser cutting device is beneficial to improving the cutting efficiency and quality of the battery electrode tab, so the laser cutting device used for electrode 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 passed. 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, a lot of charged dust is generated, and these charged dusts are easily attached to the strip, affecting 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 prevent the charged dust from being adsorbed on the strip 28 and ensure the processing quality of the strip 28.

[0034] Referring to Figures 1 to 9 , in an embodiment of the present utility model, the laser cutting device 10 includes a frame 1, a guiding component 2, a laser 3, and a first ion generator 4. The guiding component 2 is connected to the frame 1. The guiding component 2 is provided with a guiding channel 25 through which the strip 28 is passed. One side wall of the guiding channel 25 is provided with a light inlet hole 233. The laser 3 is connected to the frame 1. The laser 3 is used to emit laser light towards the light inlet hole 233 to cut the strip 28. The first ion generator 4 is arranged on one side of the guiding component 2 and is used to blow out ion wind to electrically neutralize the charged dust generated by cutting the strip 28.

[0035] Among them, the laser cutting device 10 further includes a coil component and a blanking roller 27. The coil component is used to unwind and transport the strip 28, so that the strip 28 penetrates into the guiding component 2 from the inlet, and after the strip 28 is cut by the laser at the light inlet hole 233 of the guiding component 2, it is further discharged from the outlet of the guiding component 2 and the blanking is completed through the blanking roller 27.

[0036] The first ion generator 4 can be selected as an ion wind bar. The ion wind bar is used to generate ions by ionization, and with the cooperation of the blowing device, an ion wind can be generated to neutralize the charged dust through the ion wind.

[0037] The laser cutting device 10 further includes a first linear module 91, a second linear module 93 and an adjusting component 95. The first linear module 91 and the second linear module 93 are used to realize the translation of the laser 3 in the first direction and the second direction. By rotating the adjusting component 95, the translation of the laser 3 in the second direction can be realized, so as to adjust the focal position of the laser 3.

[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 inlet hole 233 to cut and process the strip 28 in the guiding channel 25. 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 neutralize the charged dust to remove the charge of the charged dust, so as to avoid the charged dust being adsorbed on the strip 28, which is beneficial to ensuring the processing quality of the strip 28.

[0039] Refer to Figure 3 , in an embodiment of the present utility model, the laser cutting device 10 further includes a first connecting piece 5. One end of the first connecting piece 5 is connected to the guiding component 2, and the first ion generator 4 is slidably connected to the first connecting piece 5 in the vertical direction.

[0040] In this embodiment, the position of the first ion generator 4 can be adjusted in the vertical direction, so as to adjust the blowing position of the first ion generator 4 in the vertical direction, to ensure that the ion wind generated by the first ion generator 4 can blow to the surrounding of the charged dust in time, which is beneficial to further neutralize the charged dust and improve the dust removal rate.

[0041] Refer to Figure 3 , in an embodiment of the present utility model, a first sliding groove 41 is formed on one side of the first ion generator 4. The first sliding groove 41 extends in the vertical direction, and a first sliding part protrudes from one side of the first connecting piece 5. The first sliding part penetrates through the first sliding groove 41.

[0042] In this embodiment, by means of the cooperation between the first chute 41 and the first sliding part, it is convenient to adjust the position of the first ion generator 4 in the vertical direction, which is conducive to quickly adjusting the blowing position of the first ion generator 4 in the vertical direction.

[0043] Optionally, the second connecting plate 53 is provided with a first positioning hole 511, and a fastener is connected through the first positioning hole 511. The side of the fastener facing the first chute 41 serves as the first sliding part.

[0044] Refer to Figure 3 , in an embodiment of the present invention, the first connecting member 5 includes a first connecting plate 51 and a second connecting plate 53. One end of the first connecting plate 51 is slidably connected to the guiding component 2 in the horizontal direction, and the other end is connected to the second connecting plate 53. The first ion generator 4 is slidably connected to the second connecting plate 53 in the vertical direction.

[0045] In this embodiment, the position of the first ion generator 4 can be adjusted in the horizontal direction, so as to adjust the blowing position of the first ion generator 4 in the horizontal direction, ensuring that the ion wind generated by the first ion generator 4 can blow to the surroundings of the charged dust in time, which is conducive to further achieving the electrical neutralization of the charged dust, thereby improving the dust removal rate.

[0046] Refer to Figure 3 , in an embodiment of the present invention, one end of the first connecting plate 51 close to the guiding component 2 is provided with a second chute 531. The second chute 531 extends in the horizontal direction. A second sliding part protrudes from one side of the guiding component 2, and the second sliding part penetrates through the second chute 531.

[0047] In this embodiment, by means of the cooperation between the second chute 531 and the second sliding part, 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.

[0048] Optionally, the first connecting plate 51 is provided with a second positioning hole 235, and a fastener is connected through the second positioning hole 235. The side of the inserted fastener facing the second chute 531 serves as the second sliding part.

[0049] Refer to Figure 2 and Figure 3 , in an embodiment of the present invention, there are two first ion generators 4. 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.

[0050] In this embodiment, the ion rod extends upward in the vertical direction, which can achieve the electrical neutralization of the floating dust at high places. If 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.

[0051] Referring to Figure 8 , 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.

[0052] Among them, the second ion generator 35 can be selected as an ion air knife.

[0053] In this embodiment, the laser 3 emits light through the field lens 33 to achieve laser cutting of the strip 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, thus 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.

[0054] Referring 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 component 6. The waste collection component 6 includes a bin body 61 and a first negative pressure component 63. The bin body 61 is arranged vertically below the guiding component 2. The bin body 61 is provided with a collection hole 611. One side of the collection hole 611 facing away from the guiding component 2 is communicated with the first negative pressure component 63, and the first negative pressure component 63 is used for negative pressure adsorption of the collection hole 611.

[0055] Among them, the first negative pressure component 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 will be generated. After these charged dust are electrically neutralized by the first ion generator 4, they will 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 component 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 promptly 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 component 2, so that the falling charged dust can directly fall into the collection hole 611 of the bin body 61, avoiding the adjustment of the position of the bin body 61 and reducing the processing steps.

[0058] Referring to Figure 1 , in an embodiment of the present invention, the laser cutting device 10 further includes a second negative pressure component 73, and the second negative pressure component 73 is communicated with the light inlet hole 233 for performing negative pressure adsorption on the light inlet hole 233.

[0059] Wherein, the second negative pressure component 73 includes a second negative pressure pipe and an air pump. One end of the second negative pressure pipe is communicated with the light inlet hole 233, and the other end is communicated with the air pump.

[0060] In this embodiment, when the laser cuts the tape 28 through the light inlet hole 233, due to the rapid photothermal effect, a lot of dust will also be generated in the light inlet hole 233. The second negative pressure component 73 performs negative pressure suction on the dust in the light inlet hole 233, which is beneficial to ensuring the normal cutting of the tape 28 by the laser, thereby further improving the processing quality of the tape 28.

[0061] Referring to Figure 3 、 Figure 6 and Figure 7 , in an embodiment of the present invention, the guiding component 2 includes a first guiding member 21 and a second guiding member 23. The first guiding member 21 is connected to the frame 1, and the second guiding member 23 is movably arranged on the frame 1 along a direction close to or away from the first guiding member 21 to enclose the guiding channel 25 with the first guiding member 21.

[0062] Wherein, the guiding component 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 tape 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 tape 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 inlet hole 233. After the laser passes through the light inlet 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 away 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 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 an adsorption assembly 8. 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. A negative pressure groove 831 is recessed on the outer surface of the adsorbent 83 facing the strip 28. 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. Driven by the driving wheel 813, the conveyor belt 85 moves in a cycle around the outer surface of the adsorbent 83. The conveyor belt 85 performs negative pressure adsorption on the strip 28 passing out of the guiding channel 25 through the adsorption holes 851.

[0067] In fact, 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 a 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 move in a cycle around the outer surface of the adsorbent 83 in the clockwise or counterclockwise direction.

[0068] In this embodiment, 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, and driven by the rotation of the driving wheel 813, the conveyor belt 85 moves cyclically 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 subsequently. 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.

[0069] Refer 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.

[0070] 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.

[0071] Refer 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.

[0072] Among them, the second section 834 and the third section 833 can be integrally formed.

[0073] 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.

[0074] Refer 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 85, and the plurality of sub-conveyor belts 85 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 suction hole 851 is formed by enclosing the gap between two adjacent sub-conveyor belts 85.

[0075] Among them, the conveyor belt 85 can be a circular belt or a flat belt.

[0076] In this embodiment, a suction hole 851 is formed by enclosing the gap between two adjacent sub-conveyor belts 85. Compared with a single conveyor belt having a plurality of suction holes, this solution is beneficial to increasing the total area of the plurality of suction holes 851, improving the total suction amount of the conveyor belt 85, so as to realize the timely transmission of metal waste residue, thereby ensuring the processing quality of the strip 28.

[0077] Optionally, the conveyor belt 85 is provided with a plurality of suction holes 851, and the plurality of suction holes 851 are arranged at intervals in an array, and the metal waste residue is adsorbed through the plurality of suction holes 851 arranged in an array.

[0078] 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 spaced apart along the moving direction of the conveyor belt 85.

[0079] 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 residue, so as to further ensure the processing quality of the strip 28.

[0080] 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 spaced apart along the translation direction of the conveyor belt 85 and are rotatably connected to the adsorbing member 83. The driven wheel 815 rotates under the drive of the conveyor belt 85.

[0081] 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 residue, thereby being beneficial to further ensuring the processing quality of the strip 28.
