Abstract
Description
Technical Field
[0001] This invention relates to the field of battery technology, and in particular to an electrode roll forming apparatus and an electrode roll forming method. Background Technology
[0002] The production of lithium-ion batteries typically includes processes such as slurry preparation, coating, rolling, slitting, drying, winding, casing, welding, drying, electrolyte injection, sealing, cleaning, inkjet printing, formation, testing, capacity testing, and packaging. Among these processes, the slitting process involves cutting a long roll of copper or aluminum foil into a group of shorter electrode rolls. In the slitting electrode roll group, the electrode rolls at both ends (i.e., end electrode rolls) will have wavy edges, while the electrode rolls in the middle (i.e., middle electrode rolls) will not have wavy edges. Since the production process of lithium-ion batteries has extremely strict requirements, it is necessary to sort out the end electrode rolls.
[0003] In existing technologies, the slit electrode rolls are usually sorted manually to separate the end electrode rolls. This not only requires a large amount of manpower but also has low sorting efficiency. This is especially true for sorting large-sized batteries, whose electrode rolls are large in volume and weight. During the sorting process, a lot of manpower is needed to handle the end and middle electrode rolls.
[0004] Therefore, there is an urgent need to propose a polar roll forming equipment and a polar roll forming method to solve the above-mentioned technical problems. Summary of the Invention
[0005] One object of the present invention is to provide an electrode coil handling device that can reduce the manpower required for handling end and middle electrode coils during the sorting process.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] The equipment for handling and processing rolled materials includes:
[0008] Multiple cache units, each cache unit includes a rack and a cache shaft. One end of the cache shaft is fixed to the rack, and the other end of the cache shaft extends out of the rack. The cache shaft of some cache units is used to thread the end pole rolls, while the cache shaft of the remaining cache units is used to thread the middle pole rolls.
[0009] The moving unit includes a moving trolley and a hanging shaft. One end of the hanging shaft is fixed to the moving trolley, and the other end of the hanging shaft extends out of the moving trolley. The hanging shaft is used to hang the end pole rolls and the middle pole rolls. The moving trolley can drive the end of the hanging shaft extending out of the moving trolley to dock with and separate from the end of the buffer shaft extending out of the frame. The moving trolley is also used to transfer the end pole rolls and the middle pole rolls.
[0010] Optionally, the buffer unit further includes a first pushing mechanism, which is mounted on the frame and is used to push the end or middle pole rolls on the buffer shaft onto the hanger.
[0011] Optionally, the first pushing mechanism includes a first driving member and a first push plate. The fixed end of the first driving member is mounted on the frame, and the driving end of the first driving member is connected to the first push plate. The driving direction of the first driving member is parallel to the axial direction of the buffer shaft.
[0012] Optionally, the moving unit also includes a second pushing mechanism, which is mounted on the moving trolley and is used to push the end pole rolls and middle pole rolls on the hanger onto the buffer shaft.
[0013] Optionally, the second pushing mechanism includes a second driving member and a second push plate. The fixed end of the second driving member is mounted on the mobile trolley, and the driving end of the second driving member is connected to the second push plate. The driving direction of the second driving member is parallel to the axial direction of the hanging shaft.
[0014] Optionally, the buffer shaft includes a first buffer shaft and a second buffer shaft, the first buffer shaft and the second buffer shaft are concentric shafts, and the first buffer shaft is sleeved on the outside of the second buffer shaft. One end of the second buffer shaft extends out of the first buffer shaft and is fixed on the frame, and the other end of the second buffer shaft and the first buffer shaft both extend out of the frame. The end pole roll or the middle pole roll is sleeved on the first buffer shaft.
[0015] Optionally, the first cache axis and the second cache axis are connected by bearings.
[0016] Optionally, the hanger shaft is an air shaft.
[0017] Optionally, the moving unit further includes a first slide rail and a second slide rail, one of which extends along the x-direction and the other along the y-direction. The second slide rail is movably mounted on the first slide rail, and the moving trolley is slidably mounted on the second slide rail. The axis of the buffer shaft is at the same height as the axis of the hanging shaft.
[0018] Another objective of this invention is to provide a method for sorting end caps that is not only relatively simple, but also improves the efficiency of sorting end caps and reduces the error rate.
[0019] To achieve this objective, the present invention adopts the following technical solution:
[0020] The electrode roll feeding method, employing the aforementioned electrode roll feeding equipment, comprises a group of electrode rolls arranged sequentially and coaxially. The electrode roll feeding method includes:
[0021] Some cache units are used as cache units for the end polar volume, and the remaining cache units are used as cache units for the middle polar volume.
[0022] Hang a pole roll group on the hanging axis and record the number of pole rolls n. Transfer the first pole roll and the nth pole roll to the buffer axis of the end pole roll buffer unit, and transfer the second to (n-1)th pole rolls to the buffer axis of the middle pole roll buffer unit.
[0023] Beneficial effects:
[0024] The electrode roll sorting equipment provided by this invention hangs the electrode roll groups to be sorted on a hanging shaft. A moving trolley transfers the electrode roll groups to be sorted. Driven by the moving trolley, the hanging shaft aligns with a buffer shaft for threading end electrode rolls, transferring the end electrode rolls from the hanging shaft to the buffer shaft. Then, driven by the moving trolley, the hanging shaft separates from the buffer shaft. Similarly, driven by the moving trolley, the hanging shaft aligns with a buffer shaft for threading middle electrode rolls, transferring the middle electrode rolls from the hanging shaft to the buffer shaft. Then, driven by the transfer trolley, the hanging shaft separates from the buffer shaft. This electrode roll sorting equipment significantly reduces the manpower required for handling end and middle electrode rolls during the sorting process, effectively reducing the manpower needed for sorting end electrode rolls and improving sorting efficiency, which is beneficial for improving the production efficiency of lithium-ion batteries.
[0025] The electrode roll sorting method provided by this invention involves hanging an electrode roll group on a hanging shaft and recording the number n of electrode rolls in the group. At this time, the first and nth electrode rolls on the hanging shaft are end electrode rolls. The first and nth electrode rolls are transferred to the buffer shaft of the end electrode roll buffer unit. The second to (n-1)th electrode rolls are middle electrode rolls. The second to (n-1)th electrode rolls are transferred to the buffer shaft of the middle electrode roll buffer unit. This counting and sorting method is simpler, faster and has a lower error rate than the manual visual sorting method in the prior art, which helps to reduce manual input and improve sorting efficiency.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0034] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.
[0035] This embodiment provides an electrode roll sorting device that can reduce the manpower required to handle end and middle electrode rolls during the sorting process.
[0036] Specifically, such as Figure 1 As shown, the electrode winding processing equipment includes multiple buffer units 100 and a moving unit 200. Each buffer unit 100 includes a frame 110 and a buffer shaft 120. One end of the buffer shaft 120 is fixed to the frame 110, and the other end extends out of the frame 110. The buffer shafts 120 of some buffer units 100 are used to thread the end electrode windings 10, while the buffer shafts 120 of the remaining buffer units 100 are used to thread the middle electrode windings 20. The moving unit 200 includes a moving unit... The movable trolley 210 and the hanging shaft 220 are provided. One end of the hanging shaft 220 is fixed on the movable trolley 210, and the other end of the hanging shaft 220 extends out of the movable trolley 210. The hanging shaft 220 is used to hang the end pole roll 10 and the middle pole roll 20. The movable trolley 210 can drive the end of the hanging shaft 220 extending out of the movable trolley 210 to dock with and separate from the end of the buffer shaft 120 extending out of the frame 110. The movable trolley 210 is also used to transfer the end pole roll 10 and the middle pole roll 20.
[0037] The electrode roll sorting equipment hangs the electrode rolls to be sorted on the hanging shaft 220. A moving trolley 210 transfers the electrode rolls to be sorted. Driven by the moving trolley 210, the hanging shaft 220 aligns with the buffer shaft 120 for threading the end electrode rolls 10, transferring the end electrode rolls 10 from the hanging shaft 220 to the buffer shaft 120. Then, driven by the moving trolley 210, the hanging shaft 220 separates from the buffer shaft 120. Similarly, driven by the moving trolley 210, the hanging shaft 220 is then separated from the buffer shaft 120. Shaft 220 is connected to buffer shaft 120 for hanging the middle electrode roll 20, transferring the middle electrode roll 20 on the hanging shaft 220 to the buffer shaft 120. Then, driven by the transfer trolley, the hanging shaft 220 is separated from the buffer shaft 120. This electrode roll sorting equipment greatly reduces the manpower required to handle the end electrode rolls 10 and the middle electrode rolls 20 during the sorting process, effectively reducing the manpower requirement for sorting the end electrode rolls 10 and improving the sorting efficiency, which is conducive to improving the production efficiency of lithium-ion batteries.
[0038] Optionally, such as Figure 1 As shown, the moving unit 200 also includes a first slide rail 241 and a second slide rail 242. The first slide rail 241 is fixed to the ground and extends along the x-direction. The second slide rail 242 extends along the y-direction and is slidably mounted on the first slide rail 241. The moving trolley 210 is slidably mounted on the second slide rail 242. The axis of the buffer shaft 120 is at the same height as the axis of the hanging shaft 220, allowing the moving trolley 210 to move linearly along both the x and y directions. This facilitates precise control of the moving position of the moving trolley 210 and improves the docking accuracy between the moving trolley 210 driving the hanging shaft 220 and the buffer shaft 120. The x and y directions are... Figure 1The x and y directions are shown in the diagram. It is understood that in other embodiments, the second slide rail 242 may extend along the x direction, and the first slide rail 241 may extend along the y direction. Further, in this embodiment, the mobile trolley 210 is a rail-guided vehicle (RGV).
[0039] Optionally, such as Figure 1 As shown, this embodiment includes two second slide rails 242 and two mobile trolleys 210. The two second slide rails 242 and the two mobile trolleys 210 correspond one-to-one, and both second slide rails 242 are slidably mounted on the first slide rail 241. When one of the two mobile trolleys 210 malfunctions or needs maintenance, the other mobile trolley 210 can be started to perform the work, which is beneficial to improving production efficiency. Alternatively, when the production workload is large, both trolleys can be started to perform the work simultaneously to improve work efficiency and reduce the wear probability of each mobile trolley 210 and its corresponding second slide rail 242.
[0040] Optionally, the hanging shaft 220 is an air-expanding shaft. When the middle pole roll 20 and / or the end pole roll 10 are hung on the hanging shaft 220, the outer surface of the hanging shaft 220 bulges up to hold the middle pole roll 20 and / or the end pole roll 10 in place, thereby improving the stability of the middle pole roll 20 and / or the end pole roll 10 on the hanging shaft 220 and preventing problems such as shaking, movement or falling off of the middle pole roll 20 and / or the end pole roll 10 on the hanging shaft 220.
[0041] Optionally, such as Figure 1 and Figure 2 As shown, the buffer shaft 120 includes a first buffer shaft 121 and a second buffer shaft 122. The first buffer shaft 121 and the second buffer shaft 122 are concentric shafts, and the first buffer shaft 121 is sleeved on the outside of the second buffer shaft 122. One end of the second buffer shaft 122 extends out of the first buffer shaft 121 and is fixed on the frame 110. The other end of the second buffer shaft 122 and the first buffer shaft 121 both extend out of the frame 110. The end pole roll 10 or the middle pole roll 20 is sleeved on the first buffer shaft 121 to improve the overall structural strength of the buffer shaft 120 and the stability of its fixation on the frame 110, thereby improving the stability and reliability of the middle pole roll 20 or the end pole roll 10 sleeved on the buffer shaft 120.
[0042] Furthermore, the first buffer shaft 121 and the second buffer shaft 122 are connected by bearings to reduce the friction between the first buffer shaft 121 and the second buffer shaft 122.
[0043] Optionally, such as Figure 1 and Figure 2As shown, the buffer unit 100 also includes a first pushing mechanism, which is mounted on the frame 110. The first pushing mechanism is used to push the end pole roll 10 or the middle pole roll 20 on the buffer shaft 120 onto the hanging shaft 220, eliminating the need for manual pushing of the end pole roll 10 or the middle pole roll 20 on the buffer shaft 120 onto the hanging shaft 220, further reducing manual input and improving work efficiency.
[0044] Furthermore, such as Figure 1 and Figure 2 As shown, the first pushing mechanism includes a first driving member 131 and a first push plate 132. The fixed end of the first driving member 131 is mounted on the frame 110, and the driving end of the first driving member 131 is connected to the first push plate 132. The driving direction of the first driving member 131 is parallel to the axial direction of the buffer shaft 120. Under the drive of the first driving member 131, the first push plate 132 moves towards the hanging shaft 220 and away from the hanging shaft 220, so as to push the end pole roll 10 or the middle pole roll 20 on the buffer shaft 120 onto the hanging shaft 220. Preferably, the first driving member 131 is an electric push rod, and the extension range of the electric push rod can be adjusted, thereby adjusting the pushing distance of the first push plate 132. Of course, in other embodiments, the first driving member 131 can also be other driving devices such as a reciprocating cylinder.
[0045] Optionally, such as Figures 1 to 3 As shown, the moving unit 200 also includes a second pushing mechanism, which is mounted on the moving trolley 210. The second pushing mechanism is used to push the end pole roll 10 and the middle pole roll 20 on the hanging shaft 220 onto the buffer shaft 120, eliminating the need for manual pushing of the end pole roll 10 and the middle pole roll 20 on the hanging shaft 220 onto the buffer shaft 120, further reducing manual input and improving work efficiency.
[0046] Furthermore, such as Figures 1 to 3 As shown, the second pushing mechanism includes a second driving member 231 and a second push plate 232. The fixed end of the second driving member 231 is mounted on the moving trolley 210, and the driving end of the second driving member 231 is connected to the second push plate 232. The driving direction of the second driving member 231 is parallel to the axial direction of the hanging shaft 220. Under the drive of the second driving member 231, the second push plate 232 moves towards the buffer shaft 120 and away from the buffer shaft 120, thereby pushing the end pole roll 10 and the middle pole roll 20 on the hanging shaft 220 onto the buffer shaft 120. Preferably, the second driving member 231 is an electric push rod, and the extension range of the electric push rod can be adjusted, thereby adjusting the pushing distance of the second push plate 232. Of course, in other embodiments, the second driving member 231 can also be other driving devices such as a reciprocating cylinder.
[0047] This embodiment also provides a method for handling electrode rolls, such as the electrode roll handling method of the electrode roll handling equipment described above. The electrode roll group includes a plurality of electrode rolls arranged sequentially and coaxially. The electrode roll handling method includes:
[0048] Part of the cache unit 100 is used as the cache unit 100 of the end pole roll 10, and the remaining cache unit 100 is used as the cache unit 100 of the middle pole roll 20; a pole roll group is attached to the hanging shaft 220 and the number of pole rolls n is recorded; the first pole roll and the nth pole roll are transferred to the cache shaft 120 of the end pole roll 10 cache unit 100, and the second to (n-1)th pole rolls are transferred to the cache shaft 120 of the middle pole roll 20 cache unit 100.
[0049] The electrode roll sorting method involves hanging an electrode roll group on the hanging shaft 220 and recording the number n of electrode rolls in the group. At this time, the first and nth electrode rolls on the hanging shaft 220 are end electrode rolls 10. The first and nth electrode rolls are transferred to the buffer shaft 120 of the buffer unit 100 of the end electrode rolls 10. The second to (n-1)th electrode rolls are middle electrode rolls 20. The second to (n-1)th electrode rolls are transferred to the buffer shaft 120 of the buffer unit 100 of the middle electrode rolls 20. This counting and sorting method is simpler, faster and has a lower error rate than the manual visual sorting method in the prior art, which helps to reduce manual input and improve sorting efficiency.
[0050] The working principle and method of the electrode roll handling equipment provided in this embodiment are briefly explained below:
[0051] like Figures 1 to 3 As shown, taking a maximum of 6 polar rolls as the mounting surface on the polar roll cache axis 120 and the number of polar rolls n in a polar roll group as an example, two of the multiple cache units 100 are used as end polar roll 10 cache units 100. The two end polar roll 10 cache units 100 are used to mount the two end polar rolls 10 in the polar roll group respectively. The remaining cache units 100 are used as middle polar roll 20 cache units 100, which are used to mount the middle polar roll 20 in the polar roll group.
[0052] A pole roll assembly is attached to the hanging shaft 220. The moving trolley 210 moves the hanging shaft 220 along the x-direction. When the moving trolley 210 moves to the vicinity of an end pole roll 10 buffer unit 100, the barcode scanner mounted on the moving trolley 210 begins to scan the QR code fixed on the end pole roll 10 buffer unit 100 to determine the position coordinates of the buffer shaft 120 of the end pole roll 10 buffer unit 100. The moving trolley 210 adjusts its position in the x and y directions according to the position coordinates so that the hanging shaft 220 aligns with the buffer shaft 120.
[0053] After the hanger 220 is connected to the buffer shaft 120, the second drive unit 231 drives the second push plate 232 to push the pole roll group on the hanger 220 toward the buffer shaft 120 until the first pole roll is pushed onto the buffer shaft 120.
[0054] The mobile trolley 210 drives the hanging shaft 220 to separate from the cache shaft 120 and moves to the vicinity of a central tape 20 cache unit 100. The barcode scanner mounted on the mobile trolley 210 begins to scan the QR code fixed on the central tape 20 cache unit 100 to determine the position coordinates of the cache shaft 120 of the central tape 20 cache unit 100. The mobile trolley 210 adjusts its position in the x and y directions according to the position coordinates so that the hanging shaft 220 aligns with the cache shaft 120.
[0055] After the hanging shaft 220 is connected to the cache shaft 120, the second driving component 231 drives the second push plate 232 to push the pole roll group on the hanging shaft 220 toward the cache shaft 120 until the second to fifth pole rolls are all pushed onto the cache shaft 120.
[0056] The mobile trolley 210 drives the hanging shaft 220 to separate from the cache shaft 120 and moves to the vicinity of another end plate 10 cache unit 100. The barcode scanner mounted on the mobile trolley 210 begins to scan the QR code fixed on the end plate 10 cache unit 100 to determine the position coordinates of the cache shaft 120 of the end plate 10 cache unit 100. The mobile trolley 210 adjusts its position in the x and y directions according to the position coordinates so that the hanging shaft 220 aligns with the cache shaft 120.
[0057] After the hanging shaft 220 is connected to the buffer shaft 120, the second driving component 231 drives the second push plate 232 to push the remaining pole roll (i.e., the sixth pole roll) on the hanging shaft 220 onto the buffer shaft 120, and the moving trolley 210 drives the hanging shaft 220 to separate from the buffer shaft 120.
[0058] When the number of pole rolls on a certain buffer shaft 120 reaches 6, the moving trolley 210 drives the hanging shaft 220 to dock with the buffer shaft 120. The first driving component 131 drives the first push plate 132 to push the pole rolls on the buffer shaft 120 onto the hanging shaft 220 (at this time, the hanging shaft 220 is equipped with either end pole rolls 10 or middle pole rolls 20). Then, the moving trolley 210 drives the hanging shaft 220 to separate from the buffer shaft 120 and moves to the vicinity of the Automated Guided Vehicle (AGV). The second driving component 231 drives the second push plate 232 to push the pole rolls on the hanging shaft 220 onto the AGV. At this time, the pole rolls transferred from the hanging shaft 220 to the AGV are either end pole rolls 10 or middle pole rolls 20. The AGV is used to transfer the pole rolls to the next process.
[0059] It should be noted that the above-mentioned methods for determining the position coordinates of the buffer axis 120 by scanning the QR code with a barcode scanner, and the method for the moving trolley 210 to move according to the position coordinates so that the hanging axis 220 is connected to the buffer axis 120, are both relatively mature existing technologies in the field, and will not be described in detail here.
[0060] It is understood that in other implementations, the maximum number of polar rolls that can be mounted on the polar roll cache axis 120 may be, for example, 5 or 7, or other numbers, and the number of polar rolls n in a polar roll group may be 5 or 7, or other numbers.
[0061] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
