Description

Technical Field

[0001] The invention relates to the technical field of battery pole lug laser removal dust, in particular to a dust removal device and a pole piece laser vertical cutting system. Background Art

[0002] The laser will generate a large amount of dust when cutting the pole ears. If the dust is not well controlled, it will cause high short-circuit rate and self-discharge of lithium batteries, and greater safety risks in the module. Due to the high cutting temperature of laser cutting, powdered dust will float everywhere and may damage the laser galvanometer.

[0003] When cutting horizontally, the pole piece is placed above the cutting base. On the one hand, dust will fall on the pole piece, and on the other hand, the lower surface of the pole piece will slide and rub against the cutting base, causing the pole piece to be scratched. Therefore, vertical cutting is usually used at present.

[0004] During vertical cutting, on the one hand, the dust will continue to fall due to gravity, be blown around by the air flow, and overflow to the outside of the dust removal tooling to pollute the workshop. On the other hand, the interweaving of suction and blowing will also cause the electrode to shake, resulting in poor electrode cutting effect.

[0005] For example, the comparative document with announcement number CN208929480U discloses a dust removal device for dust removal during the electrode cutting process, which includes: a dust cover having a cutting chamber, a laser inlet and a strip-shaped clearance gap for the electrode to penetrate into the cutting chamber; a wind knife assembly arranged in the dust cover for conveying high-speed airflow to the cutting chamber, which includes a first wind knife and a second wind knife, the first wind knife and the second wind knife are respectively arranged on both sides of the clearance gap, and the first wind knife is close to the laser inlet; a first suction assembly is arranged in the dust cover and is arranged opposite to the wind knife assembly in a horizontal direction, and the first suction assembly is connected to the cutting chamber; the second suction assembly is arranged below the dust cover and is connected to the cutting chamber, which includes a first suction mechanism and a second suction mechanism arranged horizontally at intervals, the gap between the first suction mechanism and the second suction mechanism corresponds to the clearance gap, and the first suction mechanism is close to the laser inlet; the number of suction arrangements of the device is too large and the blowing arrangement is unreasonable, which can easily cause turbulence and cause the electrode to shake, thereby causing the laser to lose focus, which will seriously cause the electrode to be unable to cut. Summary of the invention

[0006] The technical problem to be solved by the present invention is how to prevent the pole piece from shaking during dust removal during vertical cutting to improve the cutting effect.

[0007] The present invention solves the above technical problems through the following technical means:

[0009] Beneficial effect: through the setting of the wind speed of each wind knife component and the position of the second wind knife component; the wind speed of the first wind knife component is greater than the wind speed of the third wind knife component. The first wind knife component is located in the cutting chamber and requires a higher wind speed, that is, a high-speed airflow generates suction on the electrode.

The purpose of this setting is to prevent the airflows generated by the second and third wind knife components from crossing and thus not affecting each other. The generated dust will be guided to the dust collection chamber by the airflow of the third wind knife component, and at the same time form a wind wall to prevent dust from overflowing. The maximum wind speed of the second wind knife component can press down the electrode to prevent it from shaking.

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Embodiment 1

[0050] like Figure 1 As shown, this embodiment provides a pole piece laser vertical cutting system, including a laser 1, a dust removal device 2, a material discharging device 3, and a waste conveying and collecting device 4.

[0051] like Figure 1 , Figure 2 As shown, the dust removal device 2 is located on the left or right side of the laser 1. In this embodiment, the laser 1 is arranged on the right side of the dust removal device 2. A pole piece 6 is passed through the dust removal device 2 along the Y-axis direction. The pole piece 6 is cut by the laser 1 in the dust removal device 2 to form a finished product 61 and waste 62. The finished product 61 is output from the discharging device 3, and the waste 62 is transported and collected from the waste transporting and collecting device 4.

[0052] like Figure 1 , Figure 3 As shown, the dust removal device 2 includes a cutting chamber 21, a dust removal chamber 22, a mounting plate 23, a dust suction chamber 24, and a mounting frame 25; the pole piece 6 is located between the cutting chamber 21 and the dust removal chamber 22, the cutting chamber 21 is located on the side of the pole piece 6 away from the laser 1, the dust removal chamber 22 is located on the side of the pole piece 6 close to the laser 1, the mounting plate 23 is connected to the side where the cutting chamber 21 and the dust removal chamber 22 are connected, and the dust suction chamber 24 is abutted on the mounting plate 23; the waste conveying and collecting device 4 is fixed below the dust removal chamber 22.

[0053] like Figure 3 , Figure 4 As shown, the cutting chamber 21 includes a first base 211, a guide plate 212, a roller 213, and a first air knife assembly 214. The side wall of the first base 211 close to the dust removal chamber 22 is a cutting plate.

[0054] like Figure 3 , Figure 4 , Figure 5As shown, the interior of the first substrate 211 is provided with a first channel 2111 and a second channel 2112 from bottom to top, the first channel 2111 is arranged to penetrate, the first channel 2111 has a larger opening near the first wind knife assembly 214, which is used to guide the airflow into the cavity, and the opening away from the first wind knife assembly 214 is smaller, which is used to guide the airflow into the dust suction chamber 24. At the same time, the dust removal wind speed can be increased due to the smaller opening; a step 21111 is provided on the bottom plate of the first channel 2111, and the step 21111 is arranged near the first wind knife assembly 214. Through the cooperation of the first wind knife assembly 214 and the step 21111, a Karman vortex street can be formed to better clean the dust, and the airflow blown out of the first wind knife assembly 214 passes through the step 21111 will generate turbulence, which can prevent dust accumulation and achieve the purpose of cleaning dust; a second channel 2112 is opened above the first channel 2111, and the second channel 2112 is opened on the side close to the dust collection chamber 24; the cutting plate is made of mirror stainless steel, and a first laser through hole 2113 is opened on the cutting plate. The laser can pass through the first laser through hole 2113 to cut the pole piece 6, and the first laser through hole 2113 is connected to the first channel 2111; a long strip of slit 2114 is opened on the cutting plate above the first laser through hole 2113, and the slit 2114 is connected to the second channel 2112. The pole piece 6 is sucked onto the surface of the cutting plate through the negative pressure in the first substrate 211, which can effectively prevent the pole piece 6 from shaking.

[0055] like Figure 3 , Figure 4 , Figure 5 As shown, a first wind knife assembly 214 is fixed on the side of the first base 211 away from the dust collection chamber 24. The first wind knife assembly 214 can guide the airflow into the dust collection chamber 24 by blowing compressed air into the first channel 2111, while preventing the dust generated by cutting from accumulating in the first channel 2111; a throttle valve (not shown) is fixed on the first wind knife assembly 214, and the wind speed of the blowing air can be controlled by the throttle valve.

[0056] like Figure 4 As shown, a guide plate 212 and a roller 213 are fixed on the top wall of the first substrate 211 in sequence. In this embodiment, the angle between the guide plate 212 and the top wall of the first substrate 211 is 60 degrees. The guide plate 212 is made of polished or mirrored stainless steel. The guide plate 212 and the roller 213 are mainly used to guide the pole piece to reduce friction.

[0057] like Figure 3 , Figure 6 As shown, the dust removal chamber 22 includes a second base 221 , a mounting seat 222 , a second air knife assembly 223 , a third air knife assembly 224 , and a limiting plate 225 .

[0058] like Figure 1 , Figure 6 , Figure 7 As shown, the second substrate 221 is hollow, and a second laser through hole 2211 is formed on one side of the second substrate 221 close to the laser 1 ; a third channel 2212 is formed in the second substrate 221 along the Y axis.

[0059] like Figure 3 , Figure 6 As shown, the second wind knife assembly 223 is fixed to the top wall of the second base 221 through the mounting seat 222. The second wind knife assembly 223 can adjust the blowing angle by adjusting the screw 226, so that the airflow can blow to the pole piece, firmly attach the pole piece to the cutting board, and prevent the pole piece from shaking; the third wind knife assembly 224 is fixed on the side of the second base 221 away from the dust collection chamber 24, and can blow the dust from the second base 221 to the dust collection chamber 24 through the third channel 2212; the second wind knife assembly 223 and the third wind knife assembly 224 can control the blowing wind speed through the throttle valve;

[0060] like Figure 6 , Figure 8 As shown, the wind speed of the second wind knife assembly 223 is greater than the wind speed of the first wind knife assembly 214, which can press the pole piece 6 to prevent the pole piece 6 from shaking; the wind speed of the first wind knife assembly 214 is greater than the wind speed of the third wind knife assembly 224. The first wind knife assembly 214 is located in the cutting chamber 21 and requires a higher wind speed. The reason is that there is not only pole piece dust inside the cavity, but also large particles of dust hit by the laser on the inner wall of the cutting chamber 21. The larger wind speed can guide the large particles of dust to the dust suction chamber 24, and at the same time can generate suction to the pole piece 6 to suck the pole piece 6; The airflow of the third wind knife assembly 224 is parallel to the pole piece 6, and the wind speed of the second wind knife assembly 223 is greater than the wind speed of the third wind knife assembly 224. The purpose of this arrangement is to prevent the airflows generated by the second wind knife assembly 223 and the third wind knife assembly 224 from affecting each other. The dust particle size on the side of the pole piece 6 close to the laser 1 is smaller, so there is no need for a very high wind speed. On the contrary, excessive wind speed will generate suction that will suck up the pole piece 6 and cause it to shake. The generated dust will be guided to the dust collection chamber 24 by the airflow of the third wind knife assembly 224, and at the same time form a wind wall to prevent dust from overflowing.

[0061] like Figure 3 , Figure 6 , Figure 7 As shown, a limiting plate 225 is installed near the pole piece 6 on the second substrate 221 . The limiting plate 225 can be moved through the waist-shaped hole to guide the entry of the pole piece and prevent the pole piece 6 from shaking by reducing the distance to the pole piece 6 .

[0062] like Figure 3 , Fig. 9 , Fig.10As shown, in this embodiment, a first sealing gasket 231 is fixed on the mounting plate 23 near the dust chamber 24, and the dust chamber 24 abuts against the first sealing gasket 231; the first sealing gasket 231 is made of rubber and is fixed to the mounting plate 23 by screws through countersunk holes; a rectangular non-through opening is opened on the mounting plate 23 for installing the first sealing gasket 231, and a rectangular channel 232 is opened in the middle of the mounting plate 23, and the size of the rectangular channel 232 is consistent with the channel size of the first sealing gasket 231, which is used to guide dust; through the first sealing gasket 231 and the mounting plate 23 The rectangular channel 232 opened can observe the cutting condition of the pole piece between the cutting chamber 21 and the dust removal chamber 22, and is also convenient for cleaning the dust inside the cutting chamber 21 and the dust removal chamber 22; the mounting plate 23 is fixed on the outer wall of the cutting chamber 21 and the dust removal chamber 22, and two slot-shaped openings 233 are opened at intervals on the upper and lower sides of the mounting plate 23 close to the dust removal chamber 22. Through the setting of the slot-shaped openings 233, the dust removal chamber 22 can be moved along the X-axis, and the distance between the dust removal chamber 22 and the cutting chamber 21 is enlarged, which is convenient for replacing the pole piece 6.

[0063] like Figure 3 , Fig. 9 As shown, the dust chamber 24 is slidably connected via a mounting frame 25. The mounting frame 25 is in an inverted L-shape, but is not limited to an inverted L-shape. The mounting frame 25 is mainly used to install the dust chamber 24. A slider mounting hole 251 is provided on the mounting frame 25. A slider 252 is fixed to the bottom end of the cross plate of the mounting frame 25. The slider 252 is slidably connected to the guide rail 253. The dust chamber 24 can be pulled open as a whole through the cooperation of the slider 252 and the guide rail 253.

[0064] like Figure 3 , Fig. 9 As shown, the dust suction chamber 24 includes a first dust suction pipe 241, a second sealing gasket 242, a mounting block 243, and a dust suction chamber 244; the first dust suction pipe 241 is made of stainless steel and is connected to a dust collector (not shown), which can provide suction to generate negative pressure; the mounting block 243 is an aluminum alloy part, which is mainly used to fix the main components of the dust suction chamber 24 on the mounting frame 25, and a second sealing gasket 242 for sealing is installed between the mounting block 243 and the first dust suction pipe 241. The second sealing gasket 242 is mainly made of rubber. The mounting block 243 is fixed to the dust suction chamber 244 through a countersunk hole with a hexagon socket screw, and the dust suction chamber 244 is mainly used to collect dust; the end face of the dust suction chamber 244 is in contact with the first sealing gasket 231, and the dust suction chamber 24 can be driven away from the first sealing gasket 231 by moving the mounting frame 25.

[0065] like Figure 3 , Fig. 9 , Fig.10As shown, the channels on the cutting chamber 21 and the dust removal chamber 22 together are smaller than the rectangular channel 232 of the mounting plate 23, and the size of the through opening of the dust suction chamber 244 is consistent with the size of the rectangular channel 232, so that the dust suction chamber 24 can absorb dust in the cutting chamber 21 and the dust removal chamber 22 at the same time.

[0066] like Fig.11 As shown, the waste conveying and collecting device 4 includes a waste conveying mechanism 41 and a waste collecting mechanism 42, and the waste collecting mechanism 42 is located below the waste conveying mechanism 41;

[0067] like Fig.11 , Fig.12 , Fig.13 As shown, the waste conveying mechanism 41 includes a third base 411, a second dust suction pipe 412, a brush 413, and a conveying assembly 414. The third base 411 is hollow, and the top wall of the third base 411 is fixed on the dust removal chamber 22. The second dust suction pipe 412 is fixed through the bottom wall of the third base 411. The side of the third base 411 close to the conveying assembly 414 is open. The brush 413 is detachably connected to the third base 411, and the brush 413 can clean the dust on the conveying assembly 414. A dust guide plate 4111 is fixed below the brush 413 in the third base 411 to guide the dust to slide into the second dust suction pipe 412.

[0068] like Fig.11 , Fig.12 , Fig.13 As shown, the conveying assembly 414 is fixed on the third base 411 through a fixing seat 415, and the conveying assembly 414 includes a pulley 4141, a belt 4142, a stepper motor 4143, and a dust cover 4144; the belt 4142 is arranged near the open end of the third base 411, and a small opening is opened on the belt 4142. The dust suction wind speed provided by the second dust suction pipe 412 forms a slight negative pressure through the small holes of the belt 4142, so that the waste material sticks to the belt 4142; the belt 4142 is tensioned by two pulleys 4141, and the pulley 4141 is fixed on the fixing seat 415, and the fixing seat 415 is fixed on On the outside of the third base 411, one end of the pulley 4141 is connected to the stepper motor 4143 through the synchronous pulley and the synchronous belt. The stepper motor 4143 can drive the belt 4142 to move. The moving belt 4142 drives the brush 413 to rotate and cleans the dust on the belt 4142. The brush 413 can be detachably arranged to play a tensioning role by adjusting the distance between the brush 413 and the belt 4142. In addition, the brush 413 will wear out, so it is easy to replace. A dust cover 4144 is fixed on the outside of the fixed seat 415 to prevent dust from invading the synchronous pulley and the synchronous belt.

[0069] like Fig.11 , Fig.12 , Fig.13 As shown, the waste after the electrode cutting is transported to the waste suction port 421 opened on the waste collection mechanism 42 through the belt 4142, and the waste after the electrode cutting is sucked away through the waste suction port 421. In order to ensure that the waste can be sucked away smoothly, the wind speed of the waste suction port 421 is greater than 25m / s.

[0070] When in use, the laser 1 emits a laser, which passes through the second laser through hole 2211 to cut the electrode 6; at the same time, the three wind knife assemblies and the dust collector are started, the second wind knife assembly 223 blows out an airflow to press the electrode, and the dust suction chamber 24 generates a negative pressure in the second channel 2112 through the dust collector to suck the electrode 6, the first wind knife assembly 214 blows the dust generated in the cutting chamber 21 into the dust suction chamber 24, and the third wind knife assembly 224 blows the dust generated in the dust removal chamber 22 into the dust suction chamber 24; the electrode 6 after being cut, the finished product 61 is output from the discharging device 3, and the waste 62 is sucked by the negative pressure provided by the waste conveying mechanism 41 and sent to the waste collection mechanism 42.
