Description

Technical Field

[0001] This utility model belongs to the field of battery production equipment technology, specifically an electrode laser cutting device. Background Technology

[0002] In the battery cell manufacturing process, laser in-line cutting is generally used on the production line to cut electrodes into structures such as tabs. In the production line of stacked batteries, whether the tabs are cut from the electrode strip first and then the electrode strip is cut to obtain the electrode sheet, or the electrode strip is cut into electrode sheets first and then the tabs are cut from the electrode sheets, the tabs protrude from the electrode sheet. Under the action of gravity and cutting stress, the tabs will deform relative to the electrode sheet, causing the tabs and the electrode sheet to be non-coplanar. During the continuous conveying process of the production line, the tabs may interfere with the conveying mechanism of the production line, which will not only reduce the electrode sheet conveying speed, but may even cause the tabs to break and be scrapped.

Detailed Implementation

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0038] like Figure 1-2 As shown, the electrode laser cutting apparatus of this embodiment includes a driving device 10, a laser cutting device, and a smoothing component 25. Specifically, the driving device 10 is used to drive the electrode to move along the electrode driving channel; the laser cutting device is used to perform laser cutting on the electrode; and the smoothing component 25 is used to smooth the electrode tabs obtained by laser cutting. In this embodiment, the laser cutting apparatus includes laser cutting units 20 respectively disposed on both sides of the electrode driving channel. The laser cutting unit 20 includes a laser optical path assembly 21 for performing laser cutting on the electrode and an optical path adjustment assembly 22 for adjusting the position of the laser optical path assembly 21 in the horizontal and vertical directions perpendicular to the electrode driving channel.

[0039] In this embodiment, the production method involves first cutting the electrode strip into electrode sheets, and then laser-cutting the tabs on the electrodes. Of course, in other embodiments, the production method can also be adopted by first laser-cutting the tabs on the electrode strip, and then cutting the electrode strip into electrode sheets. The principle is the same, and will not be described in detail here.

[0040] Specifically, since this embodiment first cuts the electrode strip into electrode sheets and then performs laser cutting on the electrode tabs, in order to achieve continuous and stable conveying of the electrode sheets and meet the requirements of laser cutting, the driving device 10 of this embodiment adopts a flat-pressure type electrode laser cutting device.

[0041] The flat-pressure electrode laser cutting device of this embodiment includes a flat-pressure electrode driving device 10 and a laser cutting device. The flat-pressure electrode driving device 10 is used to drive the electrode to move along a set direction; the laser cutting device is used to cut the electrode.

[0042] Specifically, the flat-pressure electrode driving device 10 of this embodiment includes two flat-pressure electrode driving units arranged opposite to each other; of the two flat-pressure electrode driving units, the one located above is the upper flat-pressure electrode driving unit 11, and the one located below is the lower flat-pressure electrode driving unit 12. An electrode driving channel for driving electrode movement is formed between the upper flat-pressure electrode driving unit 11 and the lower flat-pressure electrode driving unit 12.

[0043] like Figure 3-5 As shown, the flat-pressure electrode driving unit of this embodiment includes a mounting frame 13. Guide rails 14 are respectively provided on both sides of the mounting frame 13, forming a circumferential ring. Specifically, the guide rails 14 include arc-shaped track segments 141 located at the front and rear ends of the mounting frame 13, respectively. The ends of the two arc-shaped track segments 141 are connected by two non-intersecting straight track segments 142. Specifically, the electrode driving channel is located between two adjacent straight tracks 142 belonging to the upper flat-pressure electrode driving unit 11 and the lower flat-pressure electrode driving unit 12, respectively.

[0044] In this embodiment, the guide rail is provided with a pressure plate unit 15 that slides with it and presses the electrode sheet or electrode strip in a flat pressing manner. In this embodiment, there are at least two sets of pressure plate units 15. The mounting frame 13 is provided with a pressure plate driving unit 16 corresponding to each set of pressure plate units 15. The pressure plate driving unit 16 is used to drive the corresponding set of pressure plate units to move along the guide rail.

[0045] like Figure 6As shown, in this embodiment, the pressure plate unit 15 includes a base assembly and a pressure plate assembly. The base assembly includes base side plates 151 located on both sides of the mounting frame 13 and slidably engaged with the corresponding guide rails 14, and a base bottom plate 152 connected to the two base side plates 151. The pressure plate assembly includes a mounting plate 153 and a pressure plate 154. Both the mounting plate 153 and the pressure plate 154 are parallel to the axis of the arc track segment 141, and the pressure plate 153 is fixedly mounted on the mounting plate 153. A linear guide rod 155 perpendicular to the base bottom plate 152 is provided on the base bottom plate 152. The mounting plate 153 is slidably engaged with the linear guide rod 155, and a compression spring 156 is installed between the mounting plate 153 and the base bottom plate 152.

[0046] In a preferred embodiment of this example, rollers 157 are mounted on the base side plate 151, located above and below the corresponding guide rails. The rollers 157 roll in contact with the corresponding guide rails 14, reducing the resistance to the movement of the pressure plate unit 15 along the guide rails 14. In this embodiment, four rollers 157 are mounted on the base side plate 151, with two rollers 157 located above the guide rails 14 and the other two rollers 157 located below the guide rails 14, which helps to maintain the stability of the pressure plate unit 15 during its movement along the guide rails 14.

[0047] like Figure 5 As shown, in this embodiment, the pressure plate drive unit 16 includes a servo motor 161 and two synchronous pulleys 162 coaxially arranged with the two arc track segments 141 respectively. A synchronous belt 163 is sleeved between the two synchronous pulleys 162, and the synchronous belt 163 is connected to a corresponding set of pressure plate units 15. The servo motor 161 is mounted on the mounting bracket 13, and the servo motor 161 is drivenly connected to one of the synchronous pulleys 162. The corresponding set of pressure plate units 15 is fixedly connected to the corresponding synchronous belt 163.

[0048] Specifically, in this embodiment, the pressure plate unit 15 is configured as two sets, and the pressure plate drive unit 16 is configured as two, that is, there are two servo motors 161. The two servo motors 161 are coaxially arranged with one of the arc track segments 141 and are respectively located on both sides of the mounting bracket 13. Of course, in some other embodiments, the two servo motors 161 can also be coaxially arranged with the two arc track segments 141 respectively, which will not be described in detail here.

[0049] The flat-pressure electrode driving unit of this embodiment also includes a constraint track 17 for adjusting the distance between the pressure plate 154 and the base plate 152. The constraint track 17 includes an arc-shaped constraint track 171 corresponding to the arc track segment 141. The two ends of the arc-shaped constraint track 171 are provided with guide segments 172. The guide segment located on the entrance side of the arc-shaped constraint track 171 is used to guide the pressure plate unit 15 into the track and gradually reduce the distance between the pressure plate 154 and the base plate 152. The guide segment located on the exit side of the arc-shaped constraint track 171 is used to guide the pressure plate unit 15 out of the track and gradually increase the distance between the pressure plate 154 and the base plate 152. A constraint wheel seat 158 ​​is installed on the base plate 152, and a constraint wheel 159 that cooperates with the constraint track 17 is installed on the constraint wheel seat 158. Specifically, at the entrance side of the electrode driving channel, corresponding to the exit sides of the two constraint tracks 17 respectively set in the upper flat-pressure electrode driving unit 11 and the lower flat-pressure electrode driving unit 12, under the guidance of the corresponding guide section 172, the distance between the pressure plate 154 and the base plate 152 gradually increases, thereby allowing the pressure plate 154 to extend in a direction perpendicular or approximately perpendicular to it, so that the pressure plate 154 gradually fits against the electrode or electrode strip, and finally presses the electrode or electrode strip tightly. Correspondingly, at the exit side of the electrode driving channel, corresponding to the entrance sides of the two constraint tracks 17 respectively set in the upper flat-pressure electrode driving unit 11 and the lower flat-pressure electrode driving unit 12, under the guidance of the corresponding guide section 172, the distance between the pressure plate 154 and the base plate 152 gradually decreases, thereby allowing the pressure plate 154 to retract in a direction perpendicular or approximately perpendicular to it, so that the pressure plate 154 gradually separates from the electrode or electrode strip, and finally achieves the technical purpose of releasing the electrode or electrode strip.

[0050] Furthermore, in the lower flat-pressure electrode drive unit 12, a straight constraint track 173 is provided between the guide sections 172 of the two arc-shaped constraint tracks 171, located on the lower side of the electrode drive channel. The straight constraint track 173 is used to fix the relative arrangement between the pressure plate 154 and the base plate 152. Specifically, the pressure plate units 15 located on the upper and lower sides of the electrode drive channel are both subjected to pressure, and the compression spring 156 shortens under pressure. However, due to factors such as vibration during the conveying process of the electrode or electrode strip, the pressure is not stable enough, causing the compression spring 156 to vibrate, which in turn leads to instability of the electrode or electrode strip during the conveying process. By providing a straight constraint track 173 on the lower side of the electrode drive channel to fix the relative arrangement between the pressure plate 154 and the base plate 152, the vibration of the electrode or electrode strip during the conveying process can be effectively reduced or even eliminated, improving the conveying stability.

[0051] The flat-pressure electrode laser cutting device of this embodiment also includes a spacing adjustment component for adjusting the spacing between the upper flat-pressure electrode driving unit 11 and the lower flat-pressure electrode driving unit 12 to adjust the flat pressure on the electrode or electrode strip. Figure 2 As shown, the spacing adjustment component in this embodiment is only used to adjust the position of the upper flat-pressure electrode driving unit 11. Of course, in some other embodiments, the spacing adjustment component may also be used only to adjust the position of the lower flat-pressure electrode driving unit 12; in other embodiments, the spacing adjustment component may also adjust the positions of the upper flat-pressure electrode driving unit 11 and the lower flat-pressure electrode driving unit 12 at the same time.

[0052] Specifically, such as Figure 2 As shown, the spacing adjustment assembly in this embodiment includes a servo motor 181 and a vertical track assembly and a vertical drive assembly arranged at intervals. Specifically, the vertical track assembly includes a fixed vertical adjustment track 182 and a vertical adjustment slider 183 that slides with the vertical adjustment track. The mounting bracket 13 is fixedly connected to the vertical adjustment slider 183. The vertical drive assembly includes a vertical adjustment screw 184. The servo motor 181 is drivenly connected to one of the vertical adjustment screws 184, and the vertical adjustment screws 184 are drivenly connected to each other through a synchronous belt mechanism 185.

[0053] In this embodiment, the laser cutting device includes laser cutting units 20 respectively disposed on both sides of the electrode driving channel. The laser cutting unit 20 includes a laser optical path assembly 21 for performing laser cutting on the electrode and an optical path adjustment assembly 22 for adjusting the position of the laser optical path assembly 21 in the horizontal and vertical directions perpendicular to the electrode driving channel.

[0054] In a preferred embodiment of this example, the laser cutting unit further includes a dust extraction component, which is used to extract dust and other contaminants generated during laser cutting using negative pressure. Specifically, as shown... Figure 7 As shown, the vacuuming assembly includes a vacuum hood 23 corresponding to the laser optical path assembly and a vacuuming pipe 24 connected to the vacuum hood 23. Specifically, as... Figure 8 As shown, the dust collection hood 23 includes a hood 231 with an opening facing the front side of the electrode driving channel. The front side of the hood 231 is provided with a clearance notch 232 to allow the edge of the electrode to be located inside the hood. The top surface of the hood 231 is provided with a through hole 233 for the laser excited by the laser optical path assembly 21 to irradiate the edge of the electrode to perform laser cutting on the electrode.

[0055] The laser cutting apparatus in this embodiment also includes a smoothing component 25, which is used to smooth the tabs obtained by laser cutting. Specifically, as shown... Figure 9-11As shown, the smoothing assembly 25 includes a smoothing mounting plate 251, on which smoothing support plates 252 and smoothing pressure plates 253 are provided, which are parallel to each other. A smoothing channel 254 is formed between the smoothing support plates 252 and the smoothing pressure plates 253 for smoothing the tabs cut by the laser cutting device on the side of the electrode sheet.

[0056] Specifically, the smoothing assembly 25 also includes a waste receiving assembly for recycling waste generated from laser cutting of the electrode sheet. The waste receiving assembly includes a waste hopper 255 located below the incoming material side of the smoothing channel 254. A first air inlet 256 is provided on the smoothing pressure plate 253 directly above the waste hopper 255, and the portion of the smoothing support plate 252 on the waste hopper 255 is shortened to avoid obstructing the first air inlet 256. In this embodiment, an air blowing pipe 257 is installed on the smoothing mounting plate 251 to blow the cut waste into the waste hopper 255 through the first air inlet 256. Thus, when the electrode sheet reaches the smoothing channel 254, under the action of the high-pressure airflow blowing downwards from the first air inlet 256, the waste generated from laser cutting at the edge of the electrode sheet is blown down into the waste hopper 255, and the waste hopper 255 is connected to a negative pressure pipe 258 to suck away the waste.

[0057] In a preferred embodiment of this example, a smoothing drive belt assembly is mounted on the smoothing mounting plate 251 to improve the smoothing effect on the electrode tabs. Specifically, the smoothing drive belt assembly includes pulleys 259 located at both ends of the smoothing mounting plate 251 and a drive belt 260 sleeved on the pulleys 259. The drive belt 260 passes through the smoothing channel 254 and is located on the upper side of the electrode plate. A smoothing motor 276, which is pulsatorically connected to one of the pulleys 259, is mounted on the smoothing mounting plate 251. The smoothing drive belt assembly in this embodiment is provided with a tensioning component 261 to ensure that the drive belt 260 has sufficient tension to smooth the electrode tabs. In a preferred embodiment of this example, to prevent the drive belt 260 from obstructing the first air inlet 256, a perforation 262 is provided on the drive belt 260 corresponding to the first air inlet 256.

[0058] In this embodiment, the smoothing plate 252 has a guide slope 263 at one end on the material receiving side of the smoothing channel 254 to guide the electrode sheet into the smoothing channel 254. Further, the smoothing assembly also includes a guide control component for controlling the electrode tip to enter the smoothing channel 254 through the guide slope 263. In this embodiment, the guide control component includes a second air inlet 264 disposed on the waste receiving hopper 255 and an air pipe 265 corresponding to the second air inlet 264. The second air inlet 264 is disposed on the side of the waste receiving hopper 255 facing the material receiving side of the smoothing channel 254. In this embodiment, the air outlet 2651 of the air pipe 265 is disposed on its side wall. One end of the air pipe 265 is connected to an air blowing shaft 266, and the other end is connected to a high-pressure air pipe 267. The air pipe 265 has an air blowing chamber inside, and both the high-pressure air pipe 267 and the air outlet are connected to the air blowing chamber. The guidance control assembly also includes a blowing direction control mechanism for driving the blowing shaft 266 to rotate to adjust the blowing direction of the blowing pipe 265. Specifically, the blowing direction control mechanism includes a direction control motor 268, the output shaft of which is connected to the blowing shaft 266 via a synchronous belt mechanism 269. In this embodiment, the blowing direction control mechanism also includes a sensor 270 for detecting the rotation direction of the blowing shaft 266.

[0059] The laser cutting apparatus of this embodiment also includes a backplate assembly, which is positioned directly below the laser optical path assembly 21, with the electrode located between the laser optical path assembly 21 and the backplate assembly. The backplate assembly includes a fixedly mounted backplate base 271, on which a backplate slide rail 272 perpendicular to the electrode driving channel and a backplate slider slidably engaged with the backplate slide rail are provided. A backplate box 273 is mounted on the backplate slider, and negative pressure holes 274 are arrayed on the top surface of the backplate box 273. The backplate box 273 is connected to a negative pressure tube 275. Thus, through the negative pressure holes 274 arrayed on the top surface of the backplate box 273, a negative pressure adsorption effect can be generated on the edge portion of the electrode during laser cutting, thereby improving the positional stability of the electrode edge portion during laser cutting.
