[0037] In the stage of manufacturing the battery cell, shortening the replacement time of the separator roll has become a key factor in improving the overall production efficiency. However, in current production practices, the operational complexity and inconvenience of operation and maintenance in the manual separator roll replacement method have become the main problems affecting the production efficiency of the battery cell.
[0038] Traditional diaphragm roll changing methods often rely on manual operations during machine stoppage. Especially when changing the upper diaphragm roll, operators need to use a ladder to complete the task, which not only increases labor intensity but also poses obvious safety hazards and greatly limits the improvement of production efficiency.
[0039] To address the above challenges, this application focuses on an automatically roll-changing and tape-connecting device for diaphragms with innovative design, replacing traditional manual operations with automation, aiming to significantly improve the efficiency of diaphragm roll changing during the production of lithium batteries. This device abandons the manual machine stoppage and the operation mode of using a ladder in traditional methods. By introducing an automated tape-connecting system, it realizes the function of seamlessly connecting new and old diaphragm rolls in the production process. This improvement not only greatly reduces the time required for roll changing, thus improving the overall production efficiency, but also significantly reduces the dependence on labor and potential safety risks. In addition, by simplifying the device structure design and enhancing the convenience of operation and maintenance, this application further optimizes the production environment, enabling operators to perform tasks more safely and efficiently, thus effectively solving the problems regarding the structure and maintenance of the diaphragm roll-changing connecting device during the production of battery cells in the lithium battery industry.
[0040] In summary, this application elaborates on the challenges faced by the lithium battery industry in improving production efficiency, shortening the diaphragm roll changing time, and optimizing the structure and maintenance convenience of the diaphragm roll-changing connecting device, aiming to enhance the efficiency and safety of the entire battery cell production process by introducing automated solutions.
[0041] Specifically, please refer to Figures 1 to 9 , an automatically roll-changing and tape-connecting device 10 for diaphragms is provided in an embodiment of the utility model, which includes a mounting plate 100, a first roll 200, a second roll 300, and a roll-changing mechanism 400.
[0042] Among them, the first roll 200 and the second roll 300 are both arranged on the mounting plate 100 and are both used for mounting the diaphragm roll 20; the roll-changing mechanism 400 includes a driving source 410, a first swing roll 420, and a second swing roll 430. The driving source 410 is arranged on the mounting plate 100 and is located between the first roll 200 and the second roll 300. The first swing roll 420 and the second swing roll 430 are both connected to the driving source 410;
[0043] The first swing roll 420 is used to bond the tail of the diaphragm roll 20 on the first roll 200 to the head of the diaphragm roll 20 on the second roll 300, and the second swing roll 430 is used to bond the tail of the diaphragm roll 20 on the second roll 300 to the head of the diaphragm roll 20 on the first roll 200.
[0044] First of all, it should be noted that as Figure 1As shown, both the first material roll 200 and the second material roll 300 are installed with diaphragm rolls 20, and the two diaphragm rolls 20 are used successively. For example, the diaphragm roll 20 arranged on the first material roll roller 200 is discharged first, and after the diaphragm roll 20 on the first material roll roller 200 is used, the diaphragm roll 20 arranged on the second material roll roller 300 is used. At this time, a new diaphragm roll 20 can be installed on the first material roll roller 200, so that the diaphragm roll 20 on the first material roll roller 200 can be used again after the diaphragm roll 20 on the second material roll roller 300 is used, and the cycle is repeated.
[0045] Therefore, in this embodiment, after the membrane roll 20 of the first roll roller 200 is used up, Figure 2 As shown, the membrane roll 20 disposed on the first roll roll 200 can be moved by the first swing roller 420 so that the tail of the membrane roll 20 is connected to the head of the membrane roll 20 disposed on the second roll roll 300; and after the membrane roll 20 on the second roll roll 300 is used up, as shown in FIG. Figure 3 As shown, the diaphragm roll 20 disposed on the second roll roller 300 can be pulled by the second roll roller 300 so that its tail is connected with the tail of the diaphragm roll 20 disposed on the first roll roller 200, thereby realizing the automatic continuous roll change and connection of the diaphragm roll 20, optimizing the cell winding production process and significantly improving the production efficiency. It can be seen that the present application provides a diaphragm automatic roll change and tape splicing device 10 with a simplified structural design, aiming to facilitate the smooth operation management and daily maintenance operations.
[0046] It is worth mentioning that by coating the head portion of the diaphragm roll 20 with an adhesive substance or tape, the tail portion of one diaphragm roll 20 can be bonded to the head portion of another diaphragm roll 20 .
[0047] Furthermore, the driving source 410 includes two first driving members 411 and two reducers 412. The two first driving members 411 are both arranged on the mounting plate 100. The two reducers 412 are respectively connected to the two first driving members 411 in transmission. The first swing roller 420 and the second swing roller 430 are respectively connected to the two reducers 412. The first driving member 411 is used to drive the first swing roller 420 or the second swing roller 430 to perform circular motion.
[0048] In this embodiment, the two first driving members 411 respectively drive the first swing roller 420 and the second swing roller 430 to rotate through the two reducers 412, so as to respectively move the diaphragm roll 20 arranged on the first roll roller 200 or the diaphragm roll 20 arranged on the second roll roller 300, so that the tail material of the diaphragm roll 20 is connected with the head material of another diaphragm roll 20, thereby realizing the automatic continuous roll changing and joining of the diaphragm roll 20.
[0049] It should be noted that the first swing roller 420 is provided with a first swing arm 440, and the first swing arm 440 is connected to the speed reducer 412, so as to drive the first swing arm 440 to move through the speed reducer 412, thereby driving the first swing roller 420 to perform a circular motion; the second swing roller 430 is provided with a second swing arm 450, and its principle is the same as that of the first swing arm 440, which will not be elaborated here.
[0050] Optionally, in other embodiments of the present invention, the first driving member 411 may also be other driving devices, that is, it can also drive the first swing roller 420 and the second swing roller 430 to move in a straight line direction, as long as it can drive the diaphragm coil 20 to realize automatic coil changing, and no specific limitation is made here.
[0051] Furthermore, the diaphragm automatic coil changing and tape connecting device 10 further includes a cutting mechanism 500. The cutting mechanism 500 is arranged on the mounting plate 100 and is used to cut off the tail of the diaphragm coil 20 arranged on the first coil roller 200 or the second coil roller 300.
[0052] In this embodiment, after the tail material of the diaphragm coil 20 is connected to the head material of another diaphragm coil 20, the remaining part of the tail material of the diaphragm coil 20 can be cut off by the cutting mechanism 500.
[0053] It should be noted that in other embodiments of the present invention, the cutting mechanism 500 may not be provided, that is, there is no need to cut off the tail material of the diaphragm coil 20, and the remaining tail material of the diaphragm coil 20 can be directly wound up; therefore, corresponding adjustments can be made according to actual needs, and no specific limitation is made here.
[0054] Furthermore, the cutting mechanism 500 includes a first mounting member 510, a second driving member 520, a cutter mounting plate 530 and a cutter 540. The first mounting member 510 is arranged on the mounting plate 100, the second driving member 520 is arranged on the first mounting member 510, the cutter mounting plate 530 is connected to the output end of the second driving member 520, the cutter 540 is arranged on the cutter mounting plate 530, and the cutter 540 is used to cut off the tail of the diaphragm coil 20 arranged on the first coil roller 200 or the second coil roller 300.
[0055] In this embodiment, the second driving member 520 can be a cylinder. The first mounting member 510 is located between the first coil roller 200 and the second coil roller 300 and at a position below them. Therefore, when it is necessary to cut the diaphragm coil 20, the piston of the second driving member 520 extends vertically upward to drive the cutter 540 to move vertically upward, so as to cut off the tail material of the diaphragm coil 20.
[0056] Furthermore, the diaphragm automatic coil changing and tape connecting device 10 further includes a deviation rectifying mechanism 600. The deviation rectifying mechanism 600 is arranged on the mounting plate 100, and the deviation rectifying mechanism 600 is used to rectify the diaphragm coil 20.
[0057] In this embodiment, a deviation rectifying mechanism 600 is provided to rectify the diaphragm coil 20, thereby correcting the lateral deviation of the diaphragm coil 20 during the conveying process.
[0058] Furthermore, the deviation rectifying mechanism 600 includes a second mounting member 610, a transmission member 620, a third driving member 630, a connecting plate 640, and a deviation rectifying roller 650. The second mounting member 610 is disposed on the mounting plate 100, the third driving member 630 is disposed on the second mounting member 610, the transmission member 620 is connected to the output end of the third driving member 630, the connecting plate 640 is connected to the transmission member 620, the deviation rectifying roller 650 is disposed on the connecting plate 640, and the third driving member 630 is used to drive the transmission member 620 and the connecting plate 640 to move, so as to drive the deviation rectifying roller 650 to approach or move away from the mounting plate 100.
[0059] In this embodiment, the third driving member 630 drives the transmission member 620 to move, and drives the connecting plate 640 to move in a direction away from or close to the mounting plate 100, thereby driving the deviation rectifying roller 650 to move in a direction away from or close to the mounting plate 100, and further driving the diaphragm coil 20 wound around the deviation rectifying roller 650 to move along with the connecting plate 640, so as to correct the position of the diaphragm coil 20.
[0060] Furthermore, the deviation rectifying roller 650 includes a first support shaft 651, a first bearing 652, a first roller shaft 653, and a first end cap 654. The first support shaft 651 is connected to the connecting plate 640, the first roller shaft 653 is rotatably disposed outside the first support shaft 651 through a plurality of first bearings 652, and the first end cap 654 is connected to the end of the first roller shaft 653; a spiral groove structure is provided on the outer wall of the first roller shaft 653.
[0061] In this embodiment, the first support shaft 651 is connected to the connecting plate 640, and the first roller shaft 653 realizes rotational movement around the first support shaft 651 through multiple groups of first bearings 652. The first end cap 654 is joined to one end of the first roller shaft 653, thereby ensuring the structural stability and functionality of the deviation rectifying roller 650.
[0062] In addition, in order to increase the friction force and prevent the diaphragm coil 20 from deviating during the transmission process, a spiral groove structure is specially provided on the outer surface of the first roller shaft 653. This design not only enhances the friction between the contact surfaces, but also helps the material to remain stable when passing through the deviation rectifying roller 650, and can also avoid the deviation of the coil position caused by the adsorption effect. Moreover, an air flow channel is designed in the spiral groove, so that when the diaphragm coil 20 passes through the deviation rectifying roller 650, the adsorption effect on the roller surface can be effectively reduced or eliminated, thereby ensuring the smooth movement and precise positioning of the coil, and significantly improving the efficiency and product quality of the production process.
[0063] Furthermore, the number of the deviation rectifying rollers 650 is at least two, and at least one of the deviation rectifying rollers 650 is located between the first swing roller 420 and the second swing roller 430.
[0064] In this embodiment, the number of the deviation rectifying rollers 650 is two. The two deviation rectifying rollers 650 are respectively arranged at two ends of the connecting plate 640 in the vertical direction, and the deviation rectifying roller 650 located below is located between the first swing roller 420 and the second swing roller 430.
[0065] Furthermore, the diaphragm automatic roll changing and tape connecting device 10 further includes a sensing mechanism 700. The sensing mechanism 700 includes a sensor 710 and a third mounting member 720. The third mounting member 720 is arranged on the mounting plate 100, the sensor 710 is arranged on the third mounting member 720, the sensor 710 is also electrically connected to the deviation rectifying mechanism 600, and the sensor 710 is used for detecting the position of the diaphragm coil 20 in real time.
[0066] In this embodiment, the sensor 710 is fixedly mounted on the third mounting member 720. The sensor 710 is also electrically connected to the third driving member 630 of the deviation rectifying mechanism 600, and is used for detecting the position of the diaphragm coil 20 in real time and transmitting the position information of the diaphragm coil 20 to the third driving member 630. When the position information meets the preset condition, the third driving member 630 is started to correct the diaphragm coil 20 through the deviation rectifying system.
[0067] Furthermore, the diaphragm automatic roll changing and tape connecting device 10 further includes a plurality of guide rollers 800. The guide roller 800 includes a second support shaft 810, a second bearing 820, a second roller shaft 830 and a second end cover 840. The second support shaft 810 is arranged on the mounting plate 100, the second roller shaft 830 is rotatably arranged outside the second support shaft 810 through a plurality of second bearings 820, and the second end cover 840 is connected to the end of the second roller shaft 830; a spiral groove structure is arranged on the outer wall of the second roller shaft 830.
[0068] In this embodiment, the guide roller 800 is composed of a second support shaft 810, a second bearing 820, a second roller shaft 830 and a second end cover 840. Among them, the second roller shaft 830 is rotatably mounted on the second support shaft 810 by means of one or more groups of second bearings 820, ensuring that the second roller shaft 830 can perform a circular motion around the second support shaft 810. In order to improve the friction performance and prevent the diaphragm coil 20 from shifting during transmission, a spiral groove structure is arranged on the surface of the second roller shaft 830. This design not only effectively increases the friction force between the contact surfaces, but also avoids the diaphragm being directly adsorbed on the roller surface, thus ensuring the stability of material transmission.
[0069] Therefore, by fixedly installing a plurality of guide rollers 800 on the mounting plate 100, the spiral grooves on the surface of the guide rollers 800 not only serve as support points to ensure the smooth passage of the separator coil 20, but also play a crucial role - when the separator passes through these guide rollers 800, the gas flowing through the spiral grooves can prevent the separator from adhering to the roller surface, thereby maintaining the smoothness and efficiency of the entire transmission process.
[0070] In summary, the present utility model provides a separator automatic roll changing and tape connecting device 10. After the separator coil 20 on the first coil roller 200 is used up, the separator coil 20 disposed on the first coil roller 200 can be toggled by the first swing roller 420 so that its tail material is connected to the head material of the separator coil 20 disposed on the second coil roller 300; and after the separator coil 20 on the second coil roller 300 is used up, the separator coil 20 disposed on the second coil roller 300 can be toggled by the second coil roller 300 so that its tail material is connected to the tail material of the separator coil 20 disposed on the first coil roller 200, thereby realizing the automatic continuous roll changing and joining of the separator coil 20, optimizing the production process flow of the battery core winding, and significantly improving the production efficiency. It can be seen that the separator automatic roll changing and tape connecting device 10 provided in the present application adopts a simplified structural design, aiming to facilitate the operation management and the smooth progress of the daily maintenance work.
