Description
Technical Field
[0001] This utility model relates to the field of battery production technology, specifically to an air flotation wrinkle removal and correction device. Background Technology
[0002] In the lithium battery electrode coating process, after the electrode comes out of the oven, a correction device is generally used to correct the electrode's alignment.
[0003] Existing alignment devices generally include a base frame, a power mechanism mounted on top of the base frame, an alignment frame, a first guide roller, a second guide roller, an arc-shaped flattening roller, and traction rollers. The alignment frame is located above and connected to the power mechanism, which drives the alignment frame to move left and right and rotate. The two ends of the first guide roller are respectively mounted on the inner sides of two first guide roller mounting plates. The second guide roller is located behind the first guide roller, and its two ends are respectively mounted on the inner sides of two second guide roller mounting plates. The arc-shaped flattening roller is located between the first and second guide rollers, and its two ends are respectively mounted on the inner sides of two flattening mounting plates. The two first guide roller mounting plates, the two second guide roller mounting plates, and the two flattening mounting plates are respectively mounted on top of the alignment frame. The base frame is connected to two traction plates arranged left and right opposite each other. The two traction plates are located in front of the first guide roller, and the two ends of the traction roller are respectively mounted on the inner sides of the two traction plates. In practical applications, after the electrode comes out of the oven, it first passes over the traction roller, then over the first guide roller, then under the arc-shaped flattening roller, and then over the second guide roller. The traction roller pulls the electrode, the first and second guide rollers support it, and the arc-shaped flattening roller flattens it. When one side of the electrode shifts to the right or left, the power mechanism drives the correction frame to rotate, for example, counterclockwise or clockwise, which in turn drives the first guide roller, the arc-shaped flattening roller, and the second guide roller to rotate synchronously, thus correcting the electrode. The power mechanism also drives the correction frame to move left and right, which in turn drives the first guide roller, the arc-shaped flattening roller, and the second guide roller to move synchronously, thus adjusting the left and right positions of the first guide roller, the arc-shaped flattening roller, and the second guide roller.
[0004] In the above structure, when the electrode passes over the traction roller from above, it is squeezed by the traction roller with a small wrap angle. If the electrode is relatively thin, it is easy for the electrode to form dead wrinkles. When the electrode passes over the arc-shaped flattening roller from below, the arc-shaped flattening roller often cannot contact the blank area of the electrode, resulting in the inability to effectively flatten the blank area of the electrode, causing dead wrinkles to appear on the electrode. At the same time, the above-mentioned correction device has contact rollers, including the traction roller, the first guide roller, the arc-shaped flattening roller, and the second guide roller. The friction with the electrode is large. When the electrode is corrected in cases of edge damage or uneven splicing, the electrode often has uneven tension, which leads to dead wrinkles or broken strips on the electrode, reducing the coating quality of the electrode.

When correcting the electrode sheet in cases of edge damage or uneven splicing, the electrode sheet will not have uneven tension, thereby avoiding dead wrinkles or strip breakage of the electrode sheet and improving the coating quality of the electrode sheet.

[0046] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.
[0047] Please refer to Figures 1 to 3 An embodiment of this utility model provides an air flotation wrinkle removal and correction device, including a base frame 10, a power mechanism 20 disposed at the top of the base frame 10, a correction frame 30, a first guide roller 40, a second guide roller 50, a first flattening air flotation plate 60, a first traction air flotation plate 70, a second traction air flotation plate 80, and a second flattening air flotation plate 90.
[0048] The power mechanism 20 is used to drive the alignment frame 30 to move left and right and rotate. This invention does not make any improvements to the power mechanism 20, the base frame 10, or the alignment frame 30. The power mechanism 20 mainly includes a lead screw module 21 and a cylinder (not shown in the figure). Figure 4 and Figure 5As shown, the alignment frame 30 has two mounting positions 32, which are located near both ends of the alignment frame 30. Each mounting position 32 contains two first support plates 33, both located near one side of the alignment frame 30. The lead screw module 21 corresponds to one of the first support plates 33. The lead screw module 21 includes a housing 211, a lead screw, a nut seat 213, and a handwheel (not shown in the figure). The top of the base frame 10 has a second support plate 212. The bottom end of the housing 211 is rotatably mounted on the top of the second support plate 212. The top of the housing 211 is open, and the inner walls at both ends of the housing 211 have two mounting holes. The two ends of the lead screw are rotatably mounted in the two mounting holes, with one end of the lead screw extending from the corresponding mounting hole and connected to the handwheel. A cylinder is located between the bottom end of the alignment frame 30 and the top end of the base frame 10, and is positioned on the top of the base frame 10. The cylinder is tilted backward, and the cylinder output... The cylinder is rotatably connected to one side of the outer casing 211. The nut seat 213 is threadedly engaged with the lead screw. The nut seat 213 and one of the first support plates 33 are connected by a first connecting shaft 214. The extension or retraction of the cylinder output end can drive the outer casing 211 to rotate relative to the second support plate 212, thereby driving the straightening frame 30 to rotate. The attached drawings of this embodiment show the state after the outer casing 211 has rotated to a predetermined angle. By turning the handwheel, the lead screw can be driven to rotate, which in turn can drive the nut seat 213 to move left and right, and then drive the straightening frame 30 to move left and right through the first connecting shaft 214. The bottom end of the straightening frame 30 is provided with a support block 31, which is close to the other side of the straightening frame 30. The bottom end of the support block 31 contacts the top end of the base frame 10 to provide support for the straightening frame 30. Another first support plate 33 has a second connecting shaft 35 at its bottom end. The second connecting shaft 35 is located at the top of the support frame 34. The bottom end of the support frame 34 is in contact with the support base plate 341 located at the top of the base frame 10. The support frame 34 corresponds to the lead screw module 21. The support frame 34 and the second connecting shaft 35 can provide support for the correction frame 30.
[0049] The first guide roller 40 is used to support the electrode sheet. The two ends of the first guide roller 40 are respectively set inside the two first guide roller mounting plates 41. The two first guide roller mounting plates 41 are arranged opposite each other and are respectively set at the top of the correction frame 30. The rotation of the correction frame 30 can drive the first guide roller 40 to rotate synchronously, and the left and right movement of the correction frame 30 can drive the first guide roller 40 to move synchronously.
[0050] In this embodiment, two linear slides 42 are respectively provided on the inner sides of the two first roller mounting plates 41. The two ends of the first roller 40 are respectively mounted on the two linear slides 42 via a first roller bearing seat. The two linear slides 42 are used to drive the first roller 40 to move up and down, thereby adjusting the height of the first roller 40. The linear slides 42 are preferably existing manual slides. By rotating the handwheel of the manual slide, the screw of the manual slide can be rotated, which in turn drives the nut of the manual slide to move up and down, thereby driving the first roller 40 to move up and down. It is understood that the linear slides can also be existing electric slides.
[0051] In this embodiment, the first guide roller 40 is preferably a threaded engraving roller. When the electrode passes over the first guide roller 40 from above, the threaded groove on the outer circumferential surface of the first guide roller 40 can generate friction with the electrode. This frictional force will cause the electrode to be expanded along the inclined direction of the thread, thereby achieving the effect of flattening the electrode. Therefore, in addition to supporting the electrode, the first guide roller 40 can also flatten the electrode to avoid the electrode from having dead wrinkles.
[0052] Combination Figure 6 and Figure 7 As shown, the second guide roller 50 is used to support the electrode sheet. The second guide roller 50 is located behind the first guide roller 40, and its two ends are respectively mounted on the inner side of two second guide roller mounting plates 51 through a second guide roller bearing seat. The two second guide roller mounting plates 51 are arranged facing each other from left to right and are respectively mounted on the top of the correction frame 30. The rotation of the correction frame 30 can drive the second guide roller 50 to rotate synchronously, and the left and right movement of the correction frame 30 can drive the second guide roller 50 to move synchronously.
[0053] In this embodiment, a plurality of exhaust grooves 501 are arranged circumferentially at intervals on the outer peripheral surface of the second roller 50. The length direction of the exhaust grooves 501 is the same as the axial direction of the second roller 50, and the number of exhaust grooves 501 can be set according to the actual situation. When the electrode passes over the second roller 50, airflow is generated between the electrode and the second roller 50 due to the relatively fast belt speed. The exhaust grooves 501 can realize the function of exhausting air, thereby avoiding the formation of dead wrinkles on the electrode.
[0054] Combination Figures 8 to 12 As shown, the first flattening air-bearing plate 60 is used to flatten the electrode sheet. The first flattening air-bearing plate 60 is located between the first guide roller 40 and the second guide roller 50. The two ends of the first flattening air-bearing plate 60 are respectively disposed on the inner sides of two flattening mounting plates 61. The two flattening mounting plates 61 are arranged facing each other from left to right and are respectively disposed on the top of the straightening frame 30. The rotation of the straightening frame 30 can drive the first flattening air-bearing plate 60 to rotate synchronously, and the left and right movement of the straightening frame 30 can drive the first flattening air-bearing plate 60 to move synchronously.
[0055] In this embodiment, two first flattening linear slides 611 are respectively provided on the inner sides of the two flattening mounting plates 61. The two ends of the first flattening air-float plate 60 are respectively mounted on the two first flattening linear slides 611 via a first flattening bracket (not shown in the figure). The two first flattening linear slides 611 are used to drive the first flattening air-float plate 60 to move up and down, thereby adjusting the height of the first flattening air-float plate 60. The first flattening linear slide 611 is preferably a conventional manual slide. By rotating the handwheel of the manual slide, the screw of the manual slide can be rotated, which in turn drives the nut of the manual slide to move up and down, thereby driving the first flattening air-float plate 60 to move up and down. It is understood that the first flattening linear slide 611 can also be a conventional electric slide.
[0056] The first flattened air flotation plate 60 includes a base 62, an arc-shaped mounting component 63, and an arc-shaped air outlet 64. One end of the base 62 has an air pipe 621 communicating with the interior of the base 62, and the other end has a mounting plate 622. The air pipe 621 is used to connect to an air supply device. The base 62 of the first flattened air flotation plate 60, its mounting plate 622, and air pipe 621 are respectively mounted on two first flattening linear slides 611 via a first flattening bracket. The top end of the base 62 of the first flattened air flotation plate 60 faces downwards, and the bottom end faces upwards. The top end of the base 62 has an arc-shaped surface. The mounting component 63 is adapted to the arc-shaped surface, tightly covering and fixing itself to the arc-shaped surface. The air outlet 64 is adapted to the mounting component 63, tightly covering and fixing itself to the outer circumferential surface of the mounting component 63. The arc-shaped surface has a first air outlet 623 that communicates with the interior of the base 60. The mounting component 63 has a second air outlet 631 that communicates with the first air outlet 623. The second air outlet 631 corresponds to the first air outlet 623. The air outlet component 64 is evenly provided with a plurality of air outlet holes (not shown in the figure), which correspond to the second air outlet 631 and communicate with it. The number of air outlet holes 631 can be set according to the actual situation. In practical applications, the electrode sheet passes under the air outlet 64 of the first flattening air float plate 60. High-speed compressed air is introduced into the base 62 of the first flattening air float plate 60 through the air pipe 621 of the air supply equipment. Subsequently, the compressed air is blown downward through the first air outlet 623, the second air outlet 631, and several air outlets of the first flattening air float plate 60, thereby suspending the electrode sheet and forming a wind pressure zone in the area above the electrode sheet. The pressure in this wind pressure zone is greater than the pressure on both sides of the electrode sheet (i.e., both sides in the width direction of the electrode sheet). The pressure in this wind pressure zone can eliminate wrinkles and shrinkage on the electrode sheet, thus achieving the flattening of the electrode sheet. Since the several air outlets of the first flattening air float plate 60 are evenly distributed on the air outlet 64, the pressure in this wind pressure zone is also evenly distributed. In this way, both the coated area and the blank area of the electrode sheet can be effectively flattened, thereby avoiding the occurrence of dead wrinkles on the electrode sheet.
[0057] In this embodiment, the inner circumferential surface of the air outlet 64 is provided with a plurality of support plates 641. The plurality of support plates 641 are spaced apart along the length direction of the air outlet 64. The support plates 641 partially pass through the second air outlet 631 and the first air outlet 623 and extend into the base 62. The support plates 641 have a first vent 6411 located in the middle and a plurality of second vents 6412 located around the first vent 6411. The number of support plates 641 and second vents 6412 can be set according to the actual situation. The provided support plates 641 can enhance the strength of the air outlet 64 to avoid deformation of the air outlet 64. The provided first vents 6411 and second vents 6412 facilitate the flow of compressed air inside the base 62.
[0058] In this embodiment, the two sides of the mounting member 63 are bent towards the bottom of the base 62 to form two mounting bends 632. The two mounting bends 632 are fixed to the two sides of the base 62, and the two mounting bends 632 can further fix the mounting member 63 and the base 62 together. The two sides of the vent member 64 are bent towards the bottom of the base 62 to form two vent bends 642. The two vent bends 642 are fixed to the side of the two mounting bends 632 away from the base 62, and the two vent bends 642 can further fix the vent member 64 and the mounting member 63 together.
[0059] Combination Figure 13 and Figure 14 As shown, the base frame 10 is connected to two traction plates 11 arranged opposite each other from left to right, and the two traction plates 11 are located in front of the first roller 40. In this embodiment, the two traction plates 11 are respectively disposed at one end of two V-shaped connectors 12, the two connectors 12 are arranged opposite each other from left to right, and the other ends of the two connectors 12 are respectively connected to the top end of the base 10. The traction plates 11 and the corresponding connectors 12 are preferably integrally formed for ease of manufacturing.
[0060] Both the first traction air flotation plate 70 and the second traction air flotation plate 80 are used to suspend and traction the electrode sheets. The two ends of the first traction air flotation plate 70 are respectively mounted on the inner sides of the two traction plates 11 via a first traction bracket (not shown in the figure). The two ends of the second traction air flotation plate 80 are respectively mounted on the inner sides of the two traction plates 11 via a second traction bracket 81. The first traction air flotation plate 70 is located in front of the first guide roller 40, and the second traction air flotation plate 80 corresponds to and is located in front of the first traction air flotation plate 70.
[0061] The structures of the first traction air flotation plate 70 and the second traction air flotation plate 80 are the same as those of the first flattened air flotation plate 60, including a base 62, an arc-shaped mounting piece 63, and an arc-shaped air outlet piece 64. The base 62 of the first traction air flotation plate 70 has its mounting piece 622 and air pipe 621 respectively set on the inner side of the two traction plates 11 through a first traction bracket. The base 62 of the second traction air flotation plate 80 has its mounting piece 622 and air pipe 621 respectively set on the inner side of the two traction plates 11 through a second traction bracket 81. The top ends of the bases 62 of the first traction air flotation plate 70 and the second traction air flotation plate 80 face upwards and the bottom ends face downwards, meaning that the air outlets 64 of both the first traction air flotation plate 70 and the second traction air flotation plate 80 are located above their bases 62. In practical applications, when the electrode passes over the air outlet 64 of the first traction air flotation plate 70, high-speed compressed air can be introduced into its base 62 through the air pipe 621 of the first traction air flotation plate 70 via the air supply equipment. Subsequently, the compressed air flows upwards through the first air outlet 623, the second air outlet 631, and several air outlet holes of the first traction air flotation plate 70. The air is blown out, thus achieving suspension and traction of the electrode sheet. This avoids contact with the electrode sheet, preventing the formation of dead wrinkles. When the electrode sheet passes over the air outlet 64 of the second traction air float plate 80, high-speed compressed air can be introduced into its base 62 through the air pipe 621 of the second traction air float plate 80 via the air supply equipment. Subsequently, the compressed air is blown upward through the first air outlet 623, the second air outlet 631, and several air outlet holes of the second traction air float plate 80, thereby achieving suspension and traction of the electrode sheet. This avoids contact with the electrode sheet, preventing the formation of dead wrinkles.
[0062] The second flattening air flotation plate 90 is used to flatten the electrode sheet. The second flattening air flotation plate 90 is located in front of the first traction air flotation plate 70 and behind the second traction air flotation plate 80. The second flattening air flotation plate 90 corresponds to the first flattening air flotation plate 60 and is partially located above the first traction air flotation plate 70 and the second traction air flotation plate 80. The two ends of the second flattening air flotation plate 90 are respectively set on the inner side of the two traction plates 11 through a second flattening bracket 91.
[0063] In this embodiment, two second flattening linear slides 111 are respectively provided on the inner sides of the two traction plates 11. The two ends of the second flattening air-float plate 90 are respectively mounted on the two second flattening linear slides 111 via a second flattening bracket 91. The two second flattening linear slides 111 are used to drive the second flattening air-float plate 90 to move up and down, thereby adjusting the height of the second flattening air-float plate 90. The second flattening linear slide 111 is preferably a conventional manual slide. By rotating the handwheel of the manual slide, the screw of the manual slide can be rotated, which in turn drives the nut of the manual slide to move up and down, thereby driving the second flattening air-float plate 90 to move up and down. It is understood that the second flattening linear slide 111 can also be a conventional electric slide.
[0064] The structure of the second flattened air-supported plate 90 is the same as that of the first flattened air-supported plate 60, including a base 62, an arc-shaped mounting component 63, and an arc-shaped air outlet 64. The top end of the base 62 of the second flattened air-supported plate 90 faces downwards and the bottom end faces upwards, meaning that the air outlet 64 of the second flattened air-supported plate 90 is located below its base 62. In practical applications, the electrode plates pass under the air outlet 64 of the second flattened air-supported plate 90, and high-speed compressed air can be introduced into its base 62 through the air supply equipment via the air pipe 621 of the second flattened air-supported plate 90. Subsequently, the compressed air passes through the first air outlet 623 of the second flattened air-supported plate 90. The second air outlet 631 and several air holes blow downwards, which suspends the electrode and creates a wind pressure zone in the area above the electrode. The pressure in this wind pressure zone is greater than the pressure on both sides of the electrode (i.e., both sides in the width direction of the electrode). The pressure in this wind pressure zone can eliminate wrinkles and shrinkage on the electrode, thus flattening the electrode. Since the several air holes of the second flattening air float plate 90 are evenly distributed on the air outlet 64, the wind pressure in this wind pressure zone is evenly distributed. In this way, both the coated area and the blank area of the electrode can be effectively flattened, thus avoiding the occurrence of dead wrinkles on the electrode.
[0065] Further, please refer to Figures 1 to 3 This utility model also includes a third guide roller 100, which is used to support the electrode sheet. The third guide roller 100 is located behind the base frame 10. The two ends of the third guide roller 100 are respectively mounted on the inner side of two third guide roller mounting plates 1001 through a third guide roller bearing seat. The two third guide roller mounting plates 1001 are arranged facing each other from left to right and are respectively mounted on one side of the base frame 10. The third guide roller 100 is a common guide roller.
[0066] Further, please refer to Figures 1 to 3 , Figure 13 and Figure 14 A first air knife 110 is provided above the first traction air flotation plate 70. The two ends of the first air knife 110 are respectively connected to the two traction plates 11 through a first air knife bracket 1101. Since the temperature of the electrode is relatively high after it comes out of the oven, the first air knife 110 can blow air onto the electrode to cool it.
[0067] Further, please refer to Figures 1 to 3 , Figure 6 and Figure 7A second air knife 120 is provided above the second roller 50. Two connecting plates 52 are respectively provided on the outer sides of the two second roller mounting plates 51. The connecting plates 52 are inclined upwards. The two ends of the second air knife 120 are respectively connected to the two connecting plates 52 through a second air knife bracket 1201. The second air knife 120 can blow air onto the electrode to further cool the electrode. The second air knife 120 can rotate and move synchronously with the second roller 50.
[0068] A dust collection box 130 is provided behind the second roller 50. Both ends of the dust collection box 130 are connected to two connecting plates 52 via a dust collection bracket 1301. One side of the dust collection box 130 faces the second roller 50 and is provided with several air inlets 1302. The number of air inlets 1302 can be set according to the actual situation. The air inlets 1302 are connected to the interior of the dust collection box 130. The other side of the dust collection box 130 is inclined upward and is provided with an air outlet 1303. The air outlet 1303 is connected to the interior of the dust collection box 130. The number of air outlets 1303 can be set according to the actual situation. The air outlet 1303 is used to connect to the exhaust equipment. The exhaust equipment can exhaust the interior of the dust collection box 130 through the air outlet 1303. Dust on the electrode sheet can enter the interior of the dust collection box 1303 through the air inlets 1302 under the exhaust action of the exhaust equipment, thereby realizing the dust removal of the electrode sheet and ensuring the coating quality of the electrode sheet. The dust collector box 1303 can rotate and move synchronously with the second roller 50.
[0069] With the above structure, in practical application, after the electrode comes out of the oven, it first passes over the air outlet 64 of the second traction air flotation plate 80, then passes under the air outlet 64 of the second flattening air flotation plate 90, then passes over the air outlet 64 of the first traction air flotation plate 70, then passes over the first passing roller 40, then passes under the air outlet 64 of the first flattening air flotation plate 60, then passes over the second passing roller 50, and then passes under the third passing roller 100. At this time, the first air knife 110 and the second air knife 120 are both located above the electrode, and the dust collector box 130 is located behind the electrode. The second traction air flotation plate 80 and the first traction air flotation plate 70 can suspend and traction the electrode, the second flattening air flotation plate 90 and the first flattening air flotation plate 60 can flatten the electrode, and the first passing roller 40, the second passing roller 50, and the third passing roller 100 can achieve… The electrode sheet is supported, and air is blown onto it through the first air knife 110 and the second air knife 120 to cool it. Dust is removed from the electrode sheet through the dust collection box 130. When one side of the electrode sheet shifts to the right or left, the power mechanism 20 drives the correction frame 30 to rotate, for example, counterclockwise or clockwise. This causes the first guide roller 40, the first flattening air flotation plate 60, the second guide roller 50, the second air knife 120, and the dust collection box 130 to rotate synchronously, thus correcting the electrode sheet. The power mechanism 20 drives the correction frame 30 to move left and right, which in turn causes the first guide roller 40, the first flattening air flotation plate 60, the second guide roller 50, the second air knife 120, and the dust collection box 130 to move left and right, thereby adjusting their left and right positions.
[0070] This invention replaces the existing traction roller and arc-shaped flattening roller with a first traction air-float plate 70 and a first flattening air-float plate 60, respectively. The first traction air-float plate 70 can suspend and traction the electrode sheet, thus avoiding contact with the electrode sheet. When the electrode sheet is relatively thin, it will not form dead wrinkles. The first flattening air-float plate 60 can achieve non-contact flattening of the electrode sheet. Since the compressed air blown out by the first flattening air-float plate 60 is evenly distributed, both the coating area and the blank area of the electrode sheet can be effectively flattened. Compared with the arc-shaped flattening roller, the flattening effect is better and dead wrinkles of the electrode sheet can be avoided. At the same time, compared with the existing correction device, the number of rollers in contact with the electrode sheet can be reduced, thereby reducing the friction between the rollers and the electrode sheet. When correcting the electrode sheet in cases of edge damage or uneven splicing, the electrode sheet will not have uneven tension, thus avoiding dead wrinkles or strip breakage, and improving the coating quality of the electrode sheet. The second flattening air flotation plate 90 can be used to flatten the electrode sheet first, thus avoiding the formation of dead wrinkles when the electrode sheet passes over the first roller. The first traction air flotation plate 80 can suspend and traction the electrode sheet, making it easier to flatten the electrode sheet through the second flattening air flotation plate 90. Furthermore, by suspending and traction the electrode sheet, contact with the electrode sheet can be avoided, and dead wrinkles will not form on the electrode sheet when it is relatively thin.
