Description

Technical Field

[0001] This utility model relates to the field of electrode drilling technology, and in particular to an electrode drilling machine. Background Technology

[0002] To increase the contact area between the electrolyte and the coating on the electrode, thereby improving battery performance, perforation is typically used to create micropores in the electrode coating, allowing the electrolyte to enter. Current technology usually employs mechanical methods, such as pressing a needle against the electrode surface, to create these micropores. This method is not only inefficient but also prone to damaging the electrode due to the mechanical force exerted by the needle, hindering production. Therefore, laser perforation has emerged as a solution. Laser perforation effectively improves efficiency while avoiding the mechanical force of traditional needles, reducing the likelihood of electrode damage. However, laser perforation generates dust, which can spread and contaminate the electrode, thus affecting its performance. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Please refer to Figures 1 to 8 An electrode punching machine includes a frame plate 1, on which a feeding roller 11 and a take-up roller 12 are disposed. An electrode strip 3 extends from the feeding roller 11 to the take-up roller 12. Along the extension path of the electrode strip 3, a first tension adjustment module b, a travel correction module c, a laser punching module d, a brush dust removal module e, a first dust removal module f, a detection module g, a second dust removal module h, an iron removal module i, a second tension adjustment module j, and a take-up correction module k are sequentially arranged. The laser punching module d includes a galvanometer mounted on the frame plate 1. The assembly includes a head 21, a dust hood 22, a tension roller assembly 25, and a dust collection component 24. The dust hood 22 has a light-transmitting hole 221 on one side wall near the vibrating head 21. The vibrating head 21 and the dust hood 22 are connected by a bellows cover 23. The light-transmitting hole 221 is located inside the bellows cover 23. The laser beam emitted from the vibrating head 21 enters the dust hood 22 through the light-transmitting hole 221. The electrode strip 3 passes through the dust hood 22 and is tensioned by the tension roller assembly 25. The dust collection component 24 is equipped with a first dust suction port, and the electrode strip 3 is located between the light-transmitting hole 221 and the first dust suction port. Figures 1 to 3 As shown, the electrode strip 3 is unwound from the unwinding roller 11 and, after being processed during the extension process, is wound up from the take-up roller 12. In this embodiment, the first tension adjustment module b and the second tension adjustment module j are used to adjust the tension of the electrode strip 3 in real time to ensure that the tension of the strip is kept within a certain range, which is conducive to smooth belt feeding; the walking correction module c and the take-up correction module k are used to correct the deviation of the electrode strip 3; the laser drilling module d is used to drill holes in the electrode strip 3; the brush dust removal module e, the first dust removal module f, and the second dust removal module h are used to remove dust from the electrode strip 3; the detection module g is used to detect the processing status of the holes on the electrode strip 3, specifically by taking pictures and detecting with a CCD camera; the iron removal module i is used to remove magnetic impurities from the electrode strip 3.

[0019] Specifically, at the laser drilling module d, the tensioning roller group 25 tensions the electrode strip 3 to create conditions for laser processing. It should be noted that the tensioning roller group 25 is located inside the dust removal hood 22, and correspondingly, the area of ​​the electrode strip 3 processed by the laser beam is also located within the dust removal hood 22. Dust and impurities generated during the laser drilling process are confined within the inner cavity of the dust removal hood 22, and are removed by the dust collection component 24, thus avoiding the risk of dust diffusion and contamination of the electrode strip 3.

[0020] In this embodiment, the dust collection assembly 24 includes a first dust collection pipe 241 and a first dust collection head 242. The first dust collection pipe 241 penetrates the side wall of the dust collection hood 22, and the first dust collection head 242 is located in the inner cavity of the dust collection hood 22 and communicates with the first dust collection pipe 241. The outlet end of the first dust collection pipe 241 is connected to a negative pressure source (not shown in the figure) to generate negative pressure at the first dust collection head 242. In this embodiment, the area of ​​the electrode strip 3 processed by the laser beam is located between the light-transmitting hole 221 and the first dust collection head 242. The first dust collection port is located on the first dust collection head 242 and is positioned facing the electrode strip 3.

[0021] Furthermore, such as Figure 4 and Figure 5 As shown, the dust collector 22 is provided with a feed inlet 223 and a discharge outlet 222. The electrode material belt 3 enters the inner cavity of the dust collector 22 from the feed inlet 223 and exits the inner cavity of the dust collector 22 from the discharge outlet 222.

[0022] like Figure 5 As shown, the tensioning roller group 25 includes two first passing rollers 251 arranged near the feed inlet 223 and two second passing rollers 252 arranged near the discharge outlet 222. The two first passing rollers 251 are arranged in parallel, and the two second passing rollers 252 are arranged in parallel. The electrode strip 3 passes through the gap between the two first passing rollers 251 and the gap between the two second passing rollers 252 in sequence. The portion of the electrode strip 3 located between the second passing roller 252 closest to the feed inlet 223 and the first passing roller 251 closest to the discharge outlet 222 constitutes the processing area 31. The processing area 31 is located between the light-transmitting hole 221 and the first dust suction port.

[0023] like Figure 5 As shown, a dust removal air knife 26 is installed inside the dust removal hood 22, with its outlet facing the area between the processing area 31 and the light-transmitting hole 221. A second suction port 224 is provided on the side wall of the dust removal hood 22 located downwind of the dust removal air knife 26. Preferably, the dust removal air knife 26 is positioned near the top of the dust removal hood 22, and the second suction port 224 is positioned near the bottom of the dust removal hood 22. Therefore, impurities in the area between the processing area 31 and the light-transmitting hole 221 can move towards the second suction port 224 under the influence of gravity, and can also be further moved towards the second suction port 224 by the action of the dust removal air knife 26, which is beneficial for further removal of impurities in the dust removal chamber. It should be noted that the second suction port 224, like the first suction port, is externally connected to a negative pressure source.

[0024] Preferably, a first filter screen 27 is provided at both the first dust suction port and the second dust suction port 224 to prevent large parts from entering the dust suction port and causing blockage.

[0025] A first suction hood 225 is provided on the outer wall of the dust removal hood 22. The first suction hood 225 is inverted cone shape and is fitted to the outside of the second suction port 224. Specifically, as shown... Figure 4 and Figure 5 As shown, the area of ​​the second suction port 224 is slightly smaller than the bottom area of ​​the dust hood 22. In this embodiment, the small end of the first dust hood 225 is equipped with a second suction pipe 2251, which is connected to a negative pressure source. During use, the airflow flows from the large end to the small end of the first dust hood 225. During this process, the flow channel area gradually decreases, the airflow velocity gradually increases, and the negative pressure atmosphere gradually strengthens, which is more conducive to removing impurities from the dust hood 22.

[0026] like Figure 4 and Figure 5 As shown, an annular air knife 226 is provided at the light-transmitting hole 221, and the annular air knife 226 is coaxial with the light-transmitting hole 221. The annular air knife 226 here can prevent impurities from entering the bellows cover 23 through the light-transmitting hole 221, so as to avoid interfering with the operation of the laser beam on the electrode strip 3.

[0027] like Figure 4 As shown, the laser drilling module d also includes a first mounting base 28 disposed on the frame plate 1. A first adjusting plate 281 is adjustablely disposed on the first mounting base 28 along the width direction of the electrode strip 3. A second adjusting plate 282 is adjustablely disposed on the first adjusting plate 281. The second adjusting plate 282 can move relative to the first adjusting plate 281 to approach or move away from the dust cover 22. The scanning head 21 is mounted on the second adjusting plate 282. Preferably, the first adjusting plate 281 is slidably mounted on the first mounting base 28 via a slide rail slider assembly, and the second adjusting plate 282 is slidably mounted on the first mounting base 28 via the slide rail slider assembly. The first adjusting plate 281 is adjusted by rotating a first lead screw 283 mounted on the first mounting base 28; specifically, the first adjusting plate 281 and the first lead screw 283 are threadedly connected. Correspondingly, the second adjusting plate 282 is adjusted by rotating a second lead screw 284 mounted on the first adjusting plate 281; specifically, the second adjusting plate 282 and the second lead screw 284 are threadedly connected. In this embodiment, the first adjustment plate 281 moves along the width of the electrode strip 3 to adjust the laser beam projection area in the width direction of the electrode strip 3; the second adjustment plate 282 can move closer to or further away from the dust cover 22, that is, the scanning lens 21 can move closer to or further away from the processing area 31 of the electrode strip 3 under the action of the second adjustment plate 282, thereby realizing the focusing of the laser beam.

[0028] like Figure 6 and Figure 7As shown, the brush dust removal module e includes a second mounting base 41 disposed on the frame plate 1. A material passage hole 411 is provided through the second mounting base 41. Two dust removal components 42 are mirror-arranged on the second mounting base 41. The two dust removal components 42 can move closer to or further away from each other, and the gap between the two dust removal components 42 forms a material passage channel. The electrode strip 3 passes sequentially through the material passage hole 411 and the material passage channel. In this embodiment, the two dust removal components 42 are slidably mounted on the upper side of the second mounting base 41 via a slide rail assembly. A cylinder is disposed on each dust removal component 42, and a limit plate is disposed on the second mounting base 41. The cylinder acts on the limit plate to drive the dust removal component 42 to slide relative to the second mounting base 41.

[0029] like Figure 7 and Figure 8 As shown, the dust removal assembly 42 includes a support plate 421 disposed on the second mounting base 41. A dust collection box 422 is mounted on the support plate 421. A rotating shaft 424 is rotatably mounted on the dust collection box 422. A brush roller 423 is detachably disposed on the rotating shaft 424. The brush roller 423 is located inside the dust collection box 422. A dust removal port 4221 is opened on the side wall of the dust collection box 422 near the material passage. The brush roller 423 can pass through the dust removal port 4221 and abut against the material passage. The electrode strip 3; a motor for driving the rotating shaft 424 is mounted on the support plate 421. A quick-release end cover 4222 is detachably mounted on the side wall of the dust collection box 422 at the end away from the motor along the axial direction of the rotating shaft 424. The rotating shaft 424 is rotatably connected to the quick-release end cover 4222. A second dust suction hood 425 is mounted on the support plate 421. The inner cavity of the dust collection box 422 is connected to the second dust suction hood 425, which is connected to a negative pressure source. In use, the brush rollers 423 of the two mirror-mounted dust collection components 42 rotate, thereby simultaneously performing dust removal operations on both sides of the electrode strip 3 passing through the material passage. The second dust suction hood 425 generates negative pressure in the dust collection box 422 under the action of the negative pressure source, thereby effectively removing impurities from the dust collection box 422. When it is necessary to replace the brush roller 423, the brush roller 423 can be axially pulled out from the rotation shaft 424 after removing the quick-release end cover 4222.

[0030] In this embodiment, a first through hole 4211 is provided through the support plate 421. The first through hole 4211 communicates with the inner cavity of the dust collection box 422. The second dust collection hood 425 is installed on the side of the support plate 421 away from the dust collection box 422 and communicates with the first through hole 4211.

[0031] Furthermore, such as Figure 8As shown, a limiting pin 4241 is provided at one end of the rotating shaft 424 near the motor. The limiting pin 4241 extends radially along the rotating shaft 424. One end of the brush roller 423 is provided with a limiting groove 4231 that matches the limiting pin 4241, allowing the limiting pin 4241 to be inserted into its corresponding limiting groove 4231. In use, the brush roller 423 is fitted over the rotating shaft 424 and pushed axially along the rotating shaft 424 toward the limiting pin 4241 so that the limiting pin 4241 is inserted into the limiting groove 4231. This arrangement enables synchronous rotation of the rotating shaft 424 and the brush roller 423.

[0032] Furthermore, in order to maintain the stability of the brush roller 423, a set screw 4232 is installed on the brush roller 423, and a limiting hole 4242 adapted to the set screw 4232 is provided on the rotating shaft 424, so that the set screw 4232 can be inserted into the corresponding limiting hole 4242.

[0033] In this embodiment, the dust collection box 422 includes a dust collection body and an upper cover, which is adjustablely mounted on the dust collection body via a hinge. During use, the upper cover is fixed to the dust collection body with screws. When the brush roller 423 needs to be replaced, the upper cover is opened to facilitate the removal of the set screws 4232.

[0034] In this embodiment, a second filter screen 43 is provided at the first through hole 4211. The function of the second filter screen 43 is the same as that of the first filter screen 27, to prevent large impurities from entering the air duct.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, there are at least two laser drilling modules d, and the processing areas of the at least two laser drilling modules d in the width direction of the electrode strip 3 do not overlap or partially overlap. In this embodiment, there are two laser drilling modules d, and preferably the processing areas of the two laser drilling modules d do not overlap in the width direction of the electrode strip 3, so that processing can be carried out in different areas in the width direction of the electrode strip 3, which can adapt to the processing of wide electrode strips 3 and improve processing efficiency.

[0036] The electrode punching machine also includes a buffer mechanism a, which is located between two adjacent laser punching modules d in the extension direction of the electrode strip 3. In use, when the electrode strip 3 is a continuously coated product, it extends directly upwards into the second laser punching module d after passing through the first laser punching module d for processing. When the electrode strip 3 is an intermittently coated product, it needs to be adjusted by the buffer mechanism a before entering the second laser punching module d for processing. That is, after processing in the first laser punching module d, the electrode strip 3 moves to the right into the buffer mechanism a, passes through the buffer mechanism a, and then enters the second laser punching module d for laser punching (the path of the intermittently coated product in the buffer mechanism a is as follows). Figure 3 (As shown by the red lines). The buffer mechanism a is existing technology in the unwinding and rewinding mechanism of the electrode strip 3, and will not be described in detail here.

[0037] In this embodiment, the first dust removal module f is an ultrasonic dust removal module, and the second dust removal module h is an air knife dust removal module, to further remove dust from both sides of the electrode strip 3 and ensure the quality of the electrode strip 3. The ultrasonic dust removal module, air knife dust removal module, first tension adjustment module b, second tension adjustment module j, traveling correction module c, iron removal module i, and winding correction module k are all existing technologies and will not be described in detail here.

[0038] In summary, the electrode punching machine provided in this embodiment can efficiently punch holes in the electrode strip 3, while effectively suppressing and removing dust and impurities generated during the punching process, which helps to ensure the quality of the electrode strip 3.

[0039] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
