Description

Technical Field

[0001] This application relates to the field of battery cell production, and more particularly to an electrode buffer device and battery cell production equipment. Background Technology

[0002] In the lithium-ion battery cell winding manufacturing process, the winding equipment needs to wind materials such as electrodes and separators into a precise laminated structure. Due to the difference in linear speed between the electrode welding / cutting process and the winding process, an electrode tension buffer device is needed to store the length of the electrodes processed in the previous process, enabling dynamic connection between different processes. In existing technologies, this device typically uses a cantilevered floating roller assembly structure, absorbing the electrode excess caused by the speed difference through the displacement changes of the floating rollers. However, in high-speed continuous production, the floating roller assembly suffers from insufficient support rigidity due to the excessive length of the cantilever structure, especially when the winding speed is frequently adjusted. The floating rollers are prone to radial bending deformation due to inertia. This deformation disrupts the tension balance of the electrodes during the buffering process, causing localized loosening or over-tightening of the electrodes, leading to lateral wrinkles and reducing the yield and quality of the cells.

[0040] This application provides an electrode buffer device, which includes a mounting plate 100, a fixed roller assembly, a floating roller assembly, and a drive assembly 400.

[0041] In some specific embodiments, the mounting plate 100 has a first end and a second end. A fixed roller assembly is fixedly disposed at the first end of the mounting plate 100. The fixed roller assembly includes a plurality of first guide rollers 110 mounted on the mounting plate 100. The floating roller assembly includes a driven slide plate 200 slidably disposed on the mounting plate 100. A plurality of support frames 300 are fixedly mounted on the driven slide plate 200. A second guide roller 120 is rotatably mounted on each support frame 300. A drive assembly 400 is fixedly mounted on the mounting plate 100. The drive assembly 400 is used to drive the driven slide plate 200 to move in the region between the first end and the second end of the mounting plate 100.

[0042] See Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, in this embodiment, by mounting both ends of the second guide roller 120 on the support frame 300, the cantilever length of the second guide roller 120 is reduced by the support frame 300, that is, both ends of the second guide roller 120 are supported, which enhances the bending resistance of the second guide roller 120. When the second guide roller 120 is driven to rise or fall by the drive assembly 400 along with the driven slide plate 200, since both ends of the second guide roller 120 are mounted on the support frame 300, the second guide roller 120 is not easy to bend. Therefore, when buffering the electrode sheet, there will be no loosening or over-tightening due to bending of the second guide roller 120.

[0043] In one embodiment, the number of first guide rollers 110 and second guide rollers 120 is the same. The first guide rollers 110 and second guide rollers 120 are staggered in the vertical height direction, and the electrode sheets pass through each first guide roller 110 and second guide roller 120 in an "S" shape. The driven slide plate 200 is driven to rise and fall by the drive assembly 400, thereby driving the second guide rollers 120 installed on each support frame 300 to rise and fall, thereby changing the length of the electrode sheet buffer.

[0044] In this embodiment, the driven slide plate 200 slides on the side of the mounting plate 100 via a guide rail slider assembly. Specifically, the moving end of the drive assembly 400 drives the driven slide plate 200 to move up and down, thereby driving the various support frames 300 and the second guide roller 120 to move up and down. Specifically, the first end mentioned above is the end of the mounting plate 100 near the top surface, and the second end is the end of the mounting plate 100 near the bottom surface.

[0045] In this embodiment, in the initial state, the floating roller assembly is located at the middle position between the first end and the second end. When the electrode tab welding or electrode tab cutting speed of the current process is lower than the winding process speed, the floating roller assembly will be driven upward by the drive assembly 400 to provide sufficient electrode sheets for the winding process. Similarly, when the electrode tab welding or electrode tab cutting speed of the current process is faster than the winding process speed, the floating roller assembly will be driven downward by the drive assembly 400 to increase the length of the electrode sheet buffer, thereby reducing the number of electrode sheets provided for the winding process.

[0046] In some specific embodiments, the first guide roller 110 and the second guide roller 120 have the same structure. Here, the first guide roller 110 is used as an example. Specifically, the first guide roller 110 includes a mounting shaft 111, a roller 112 is rotatably mounted on the circumference of the mounting shaft 111, a connecting block 113 is fixedly mounted at the end of the mounting shaft 111, a connecting rod 114 is fixedly mounted on one side of the connecting block 113, a guide plate 115 is fixedly mounted on the connecting rod 114, the guide plate 115 is located in the circumference of the roller 112, and the guide plate 115 forms a preset distance with the circumference of the roller 112; the guide plate 115 gradually extends away from the roller 112 in the radial direction.

[0047] participate Figure 5 As shown, the mounting shaft 111 is used for fixed installation. Since the first guide roller 110 does not need to move, one end of the mounting shaft 111 in the first guide roller 110 can be fixedly installed on the mounting plate 100. A roller 112 is rotatably mounted on the outer surface of the mounting shaft 111, thereby guiding the electrode sheet through rotation. Furthermore, in order to prevent the electrode sheet from bending or wrinkling during the conveying process, a guide plate 115 is provided circumferentially on the roller 112. Specifically, a connecting block 113 is fixedly installed at the end of the mounting shaft 111, and a connecting rod 114 is provided at the end of the connecting block 113 along the axial direction of the mounting shaft 111. Finally, the guide plate 115 is fixedly installed on the connecting rod 114. At this time, the guide plate 115 is located in the circumferential direction of the roller 112. In order to allow the electrode sheet to pass smoothly, there is a preset distance between the guide plate 115 and the circumferential surface of the roller 112. This distance can be adaptively adjusted according to the thickness of the electrode sheet. The specific distance is not limited here.

[0048] In order to prevent the end of the guide plate 115 from touching the electrode during the electrode conveying process, the end of the guide plate 115 can extend in the radial direction away from the roller 112. Specifically, the extended end of the guide plate 115 is at the inlet position of the preset gap.

[0049] The support frame 300 includes a frame body 310 fixedly connected to the driven slide plate 200. The frame body 310 has a mounting groove 320. The two ends of the second guide roller 120 are respectively connected to the two inner walls of the mounting groove 320. The surface of the frame body 310 facing the first end direction is provided with a second clearance groove 330 that communicates with the mounting groove 320.

[0050] See Figure 3 and Figure 4 As shown, in order to facilitate the installation of the second guide roller 120, an installation groove 320 is provided on the bottom surface of the frame 310. The two sides of the installation groove 320 are used for the fixed installation of the installation shaft 111 of the second guide roller 120. Furthermore, in order to facilitate the electrode sheet to pass through the outer surface of the roller 112 of the second guide roller 120 and be conveyed to the direction of the first guide roller 110, a second clearance groove 330 is provided on the upper surface of the frame 310 for clearance, so as to facilitate the passage of the electrode sheet.

[0051] In some specific embodiments, the drive assembly 400 is disposed on the side of the mounting plate 100 away from the direction of the fixed roller assembly. The mounting plate 100 is provided with a first clearance groove 101. The drive assembly 400 includes a linear drive member. The moving end of the linear drive member is fixedly provided with a transmission block 401. The transmission block 401 passes through the first clearance groove 101 and is fixedly connected to the driven slide plate 200.

[0052] See Figure 8As shown, in order to drive the floating roller assembly to move up and down, a drive assembly 400 is provided on the other side of the mounting plate 100 to drive it to move up and down. Specifically, the linear drive unit drives the driven slide plate 200 to rise and fall through the transmission block 401, thereby driving the support frame 300 and the second guide roller 120 to rise and fall. It can be understood that in order to fix the transmission block 401 to the driven slide plate 200, a first clearance groove 101 is opened on the side of the mounting plate 100 along the direction of the driven slide plate 200 to move up and down. This allows the transmission block 401 to be fixedly connected to the driven slide plate 200 as a transmission unit, transmitting the force from the linear drive unit to the driven slide plate 200.

[0053] In some specific embodiments, the linear drive includes a first mounting bracket 410 fixedly mounted at a first end position and a second mounting bracket 420 mounted at a second end position. A first pulley 441 is rotatably mounted on the first mounting bracket 410, and a second pulley 442 is rotatably mounted on the second mounting bracket 420. The first pulley 441 and the second pulley 442 are driven by a transmission belt 450. A transmission block 401 is fixedly mounted on the transmission belt 450. A rotary drive 430 is fixedly mounted on the first mounting bracket 410, and the rotary drive end of the rotary drive 430 is connected to the first pulley 441.

[0054] Please continue reading. Figure 8 As shown, when the rotary drive component 430 is fixedly installed on the first mounting bracket 410, in order to drive the driven slide plate 200 to rise and fall, the rotary drive component 430 transmits power to the first pulley 441, thereby driving the first pulley 441 to rotate. Since the first pulley 441 and the second pulley 442 are connected by a transmission belt 450, the transmission belt 450 rotates at the same time as the first pulley 441 rotates. With the transmission block 401 fixedly installed on the transmission belt 450, the transmission belt 450 transmits power to the driven slide plate 200 through the transmission block 401, thereby driving the driven slide plate 200 to rise and fall.

[0055] In another embodiment, a rotary drive 430 is fixedly mounted on the second mounting bracket 420, and the drive end of the rotary drive 430 is connected to the second pulley 442.

[0056] It is understood that the rotary drive component 430 is fixedly installed on the second mounting bracket 420. The rotary drive component 430 transmits power to the second pulley 442. The rotary drive component 430 drives the second pulley 442 to rotate, which in turn drives the transmission belt 450 to rotate. Therefore, the transmission belt 450 transmits power to the driven slide plate 200 through the transmission block 401, thereby driving the driven slide plate 200 to move up and down.

[0057] In some specific embodiments, a limiting component 600 is provided on one side of the second mounting bracket 420. The limiting component 600 includes a fixing member 610 fixedly mounted on the mounting plate 100. A first screwing member 620 and at least one second screwing member 630 are screwed onto the fixing member 610. The second screwing member 630 screws through the fixing member 610 and abuts against the second mounting bracket 420. The second mounting bracket 420 has a screwing hole 640 at the position of the first screwing member 620. The first screwing member 620 passes through the fixing member 610 and is connected to the screwing hole 640.

[0058] See Figure 9 and Figure 10 As shown, in order to prevent the transmission belt 450 from loosening after long-term use, it is necessary to limit it with the limiting component 600 to prevent the second mounting bracket 420 and the second pulley 442 from moving. Specifically, the second mounting bracket 420 has an elongated hole on its frame and is then bolted to the mounting plate 100. When the second mounting bracket 420 needs to be limited, the first screwing member 620 can be screwed on. Under the threaded transmission between the first screwing member 620 and the screwing hole 640, the second mounting bracket 420 gradually moves away from the first mounting bracket 410. After the transmission belt 450 is tensioned, it can be bolted through the elongated hole and mounted on the mounting plate 100. Then, the second screwing member 630 is screwed on to make it abut against the second mounting bracket 420 to prevent the second mounting bracket 420 from moving toward the first mounting bracket 410. In this embodiment, there are two second screwing members 630 located on both sides of the first screwing member 620.

[0059] In some specific embodiments, the mounting plate 100 is provided with a stop assembly 500, which includes a first mounting block 510 fixedly mounted on the driven slide plate 200, a stop pin 520 mounted on the first mounting block 510, and a second mounting block 530 fixedly mounted on the mounting plate 100, the second mounting block 530 having a stop groove 540 adapted to the stop pin 520.

[0060] See Figure 6 and Figure 7 As shown, since the distance between the first end and the second end of the mounting plate 100 is relatively large, when the electrode sheet passes through the first guide roller 110 and the second guide roller 120 for the first time, in order to improve working efficiency, the driven slide plate 200 is lifted to the position of the second mounting block 530, and then the stop pin 520 extends into the stop groove 540 to limit the driven slide plate 200 in the height direction. At this time, the distance between the first guide roller 110 and the second guide roller 120 becomes smaller, thereby reducing the length of electrode sheet insertion and improving efficiency.

[0061] For example, the stop pin 520 can be a bolt, which is tightened so that its end extends into the stop groove 540 to achieve the limit.

[0062] In some specific embodiments, a first limiting block 130 is fixedly installed at the first end of the mounting plate 100, and a second limiting block 140 is fixedly installed at the second end of the mounting plate 100.

[0063] Please continue reading. Figure 6 and Figure 7 As shown, by setting a first limiting block 130 at the top of the mounting plate 100 and a second limiting block 140 at the bottom of the mounting plate 100, the lifting and lowering of the driven slide plate 200 is limited, preventing the driven slide plate 200 from rising too high and colliding with the first guide roller 110, and preventing it from falling off the mounting plate 100 due to falling too low.
