Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery production, and particularly to an electrode roll tab commutation device. Background Art

[0002] The slitting of battery pole rolls is a process in the lithium battery production process of dividing a wide material roll into widths corresponding to the battery size. According to the width of the battery, in the slitting process, the battery will be cut from the large pole roll in the upstream coating process into 2 rolls, 4 rolls, 6 rolls, 8 rolls, 10 rolls or even more. The tab directions of adjacent small pole rolls after slitting are opposite. The two take-up shafts of the slitting equipment will wind up the material rolls with tabs in one direction together respectively. Therefore, the tab directions of the materials taken from different coaxial take-ups are opposite.

[0003] At present, the feeding direction of the material roll of the downstream process equipment is fixed. Therefore, half of the materials discharged from the slitting equipment need to be commuted. The conventional method is that two employees use a cantilever shaft forklift to resist each other, and then manually dial the material to perform a commutation, and then place the commuted material on the cantilever shaft buffer rack, and then send the commuted material to the downstream process. The whole process is complex in operation, time-consuming and laborious, and has a low degree of automation. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an electrode roll tab commutation device to solve the technical problems that the existing electrode roll tab commutation operation is time-consuming and laborious and has a low degree of automation.

[0005] To achieve the above purpose, the present invention is implemented by the following technical solutions: The present invention provides an electrode roll tab commutation device, including: A material tray, having a cantilever shaft for loading electrode rolls; A rotating station, including a feeding-side rotating station and a discharging-side rotating station. Rotating devices are provided on both the feeding-side rotating station and the discharging-side rotating station for rotating the material tray; A material dialing device, arranged on the side of the rotating station and having a fork for dialing the electrode roll on the cantilever shaft of the material tray on the feeding-side rotating station to the cantilever shaft of the material tray on the discharging-side rotating station when the cantilever shafts of the material trays on the feeding-side rotating station and the discharging-side rotating station are collinear.

[0006] In the present invention, by providing a feeding-side rotating station and a discharging-side rotating station, during operation, a fully loaded material tray is placed at the feeding-side rotating station, and an empty material tray is placed at the discharging-side rotating station. The electrode coil on one side of the cantilever shaft of the material tray at the feeding-side rotating station is toggled to one side of the cantilever shaft of the material tray at the discharging-side rotating station by a fork. After the toggling is completed, the material tray is rotated 180° by a rotating device, and then the electrode coil on the other side of the cantilever shaft of the material tray at the feeding-side rotating station is toggled to the other side of the cantilever shaft of the material tray at the discharging-side rotating station by the fork. The present invention automatically reverses the tabs of the electrode coil through the material tray, the rotating station, and the material toggling device, which is time-saving, labor-saving, and has a high degree of automation compared with the traditional reversing method.

[0007] Optionally, the material tray further includes a bottom tray and a support beam vertically arranged on the bottom tray, and the cantilever shaft is horizontally arranged on the support beam.

[0008] In the present invention, the support beam provides a supporting force for the cantilever shaft. At the same time, in order to ensure the stability of the material tray when carrying the electrode coil, the middle part of the cantilever shaft is fixed to the support beam, and the electrode coils can be loaded on both sides of the cantilever shaft of the support beam.

[0009] Optionally, the surface of the cantilever shaft is provided with rollers that roll and are arranged along its axial direction.

[0010] In the present invention, by providing rollers on the cantilever shaft, when the electrode coil is loaded on the cantilever shaft, the inner wall of the electrode coil contacts the rollers, so that the electrode coil can slide on the cantilever shaft with low friction.

[0011] Optionally, the material toggling device further includes a cross beam and leg frames correspondingly arranged on both sides. Both ends of the cross beam are slidably arranged on the leg frames, and a first driving component connected to the cross beam is arranged on the leg frames. The first driving component is used to drive the cross beam to approach or move away from the rotating station; a second driving component connected to the fork is arranged on the cross beam, and the second driving component is used to drive the fork to move back and forth along the side of the rotating station.

[0012] During the material toggling operation of the material toggling device of the present invention, the first driving component drives the cross beam to approach the rotating station, so that the fork reaches the side of the electrode coil. The second driving component drives the fork to move, and the electrode coil is pushed by the fork from the electrode coil on the cantilever shaft of the material tray at the feeding-side rotating station to the electrode coil on the cantilever shaft of the material tray at the discharging-side rotating station. The material toggling operation is stable and labor-saving.

[0013] Optionally, a first conveyor line is provided at both the loading-side rotation station and the unloading-side rotation station for conveying the material trays; a notch is provided on the first conveyor line for the rotating device to pass through and rotate the material trays on the first conveyor line.

[0014] Optionally, a loading-side transfer station is provided on one side of the loading-side rotation station away from the unloading-side rotation station, and an unloading-side transfer station is provided on one side of the unloading-side rotation station away from the loading-side rotation station; second conveyor lines are provided at both the loading-side transfer station and the unloading-side transfer station, and a passage for the AGV cart to pass through is provided in the middle of the second conveyor line. The AGV cart includes a vehicle body and a lifting mechanism provided on the top of the vehicle body, and a tray fixing seat is provided on the top driving end of the lifting mechanism.

[0015] While solving the problem of the pole ear commutation of the electrode roll, the present invention realizes the transfer of the material trays by providing the first conveyor line, the second conveyor line and the AGV cart. The fully loaded material tray is transferred by the AGV cart to the passage of the second conveyor line on the loading side, and then the fully loaded material tray is lowered onto the second conveyor line on the loading side by the lifting mechanism on the AGV cart. After the AGV cart withdraws, the second conveyor line on the loading side conveys the fully loaded material tray to the first conveyor line on the loading side. Similarly, the empty material tray is transferred by the AGV cart to the passage of the second conveyor line on the unloading side, and then the fully loaded material tray is lowered onto the second conveyor line on the unloading side by the lifting mechanism on the AGV cart. After the AGV cart withdraws, the second conveyor line on the unloading side conveys the empty material tray to the first conveyor line on the unloading side. After the fully loaded material tray and the empty material tray are both in place, the dialing operation is performed by the dialing device.

[0016] Optionally, both the first conveyor line and the second conveyor line include a fixed frame and a non-powered roller and a powered roller provided on the fixed frame.

[0017] The present invention provides the conveying power of the first conveyor line and the second conveyor line through the powered rollers, and at the same time ensures the stable conveying through the non-powered rollers. The powered rollers at each station can be independently controlled to achieve flexible conveying operations.

[0018] Optionally, the two first conveyor lines and the two second conveyor lines are of an integrated structure.

[0019] With the first conveyor line and the second conveyor line of the integrated structure in the present invention, the connection between the first conveyor line and the second conveyor line is tight, which can not only ensure the stability of the overall structure of the conveyor line, but also ensure the stability of conveying.

[0020] Optionally, the rotating device includes a lifting component, a rotating motor and a rotating table, a motor fixing seat is provided on the top driving end of the lifting component, the rotating motor is provided on the electrode fixing seat, and the main axis of the rotating motor is connected to the middle of the rotating table upward through a fixing flange.

[0021] The present invention provides a rotating device with a lifting component, which can rotate the material tray on the first conveyor line through the gap on the first conveyor line in the lifting state, thereby integrating the conveying operation and the rotating operation, making the overall structure more compact and highly integrated.

[0022] Optionally, photoelectric sensors are provided on the loading side rotary station, the unloading side rotary station, the loading side transfer station and the unloading side transfer station, and the photoelectric sensors are used to detect the material tray.

[0023] The present invention can detect whether the material tray reaches the loading side rotation station, the unloading side rotation station, the loading side transfer station and the unloading side transfer station by arranging photoelectric sensors. After obtaining the detection signal, automatic control can be performed according to the detection signal to improve the degree of automation.

[0024] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides an electrode roll and pole lug reversing device, which is provided with a feeding side rotating station and a unloading side rotating station. When working, a fully loaded material tray is placed at the feeding side rotating station, and an empty material tray is placed at the unloading side rotating station. The electrode roll on one side of the cantilever shaft of the material tray at the feeding side rotating station is moved to one side of the cantilever shaft of the material tray at the unloading side rotating station by a shift fork; after the shifting is completed, the material tray is rotated 180° by a rotating device, and then the electrode roll on the other side of the cantilever shaft of the material tray at the feeding side rotating station is moved to the other side of the cantilever shaft of the material tray at the unloading side rotating station by a shift fork. The present invention automatically reverses the electrode roll and pole lug by using a material tray, a rotating station, and a material shifting device. Compared with the traditional reversing method, it saves time and labor and has a high degree of automation.

[0025] While solving the problem of the electrode coil tab commutation, the present invention realizes the transfer of the material tray by setting up the first conveyor line, the second conveyor line and the AGV cart. The fully loaded material tray is transferred by the AGV cart to the channel of the second conveyor line on the loading side, and then the fully loaded material tray is lowered onto the second conveyor line on the loading side through the lifting mechanism on the AGV cart. After the AGV cart withdraws, the second conveyor line on the loading side conveys the fully loaded material tray to the first conveyor line on the loading side. Similarly, the empty material tray is transferred by the AGV cart to the channel of the second conveyor line on the unloading side, and then the fully loaded material tray is lowered onto the second conveyor line on the unloading side through the lifting mechanism on the AGV cart. After the AGV cart withdraws, the second conveyor line on the unloading side conveys the empty material tray to the first conveyor line on the unloading side. After both the fully loaded material tray and the empty material tray are in place, the dialing operation is performed by the dialing device to complete the transfer and commutation of the electrode coil.

[0030] Embodiment 1:

[0031] like Figure 1 As shown, an embodiment of the present invention provides an electrode roll and tab reversing device, comprising a material tray 1, a rotating station and a material shifting device 4; the material tray 1 is provided with a cantilever shaft 11, and the cantilever shaft 11 is used to load the electrode roll 7; the rotating station comprises a loading side rotating station 21 and a unloading side rotating station 22, and the loading side rotating station 21 and the unloading side rotating station 22 are both provided with a rotating device 3, and the rotating device 3 is used to rotate the material tray 1; the material shifting device 4 is arranged on the side of the rotating station, and is provided with a shift fork 41, and the shift fork 41 is used to shift the electrode roll 7 on the cantilever shaft 11 of the material tray 1 on the loading side rotating station 21 to the cantilever shaft 11 of the material tray 1 on the unloading side rotating station 22 when the cantilever shafts 11 of the material tray 1 on the loading side rotating station 21 and the unloading side rotating station 22 are in a colinear state.

[0032] In the present invention, by providing a feeding-side rotating station 21 and a discharging-side rotating station 22, during operation, a fully loaded material tray 1 is placed at the feeding-side rotating station 21, and an empty material tray 1 is placed at the discharging-side rotating station 22. The electrode coil 7 on one side of the cantilever shaft 11 of the material tray 1 at the feeding-side rotating station 21 is toggled to one side of the cantilever shaft 11 of the material tray 1 at the discharging-side rotating station 22 by a fork 41. After the toggling is completed, the material tray 1 is rotated 180° by a rotating device 3, and then the electrode coil 7 on the other side of the cantilever shaft 11 of the material tray 1 at the feeding-side rotating station 21 is toggled to the other side of the cantilever shaft 11 of the material tray 1 at the discharging-side rotating station 22 by the fork 41. The present invention automatically reverses the tabs of the electrode coil 7 through the material tray 1, the rotating station, and the material feeding device 4. Compared with the traditional reversing method, it saves time and effort and has a high degree of automation.

[0033] As Figure 2 shown, specifically in this embodiment, the material tray 1 further includes a bottom tray 12 and a support beam 13 vertically provided on the bottom tray 12. The cantilever shaft 11 is horizontally provided on the support beam 13.

[0034] The present invention provides a supporting force for the cantilever shaft 11 through the support beam 13. At the same time, in order to ensure the stability of the material tray 1 when carrying the electrode coil 7, the middle part of the cantilever shaft 11 is fixed to the support beam 13, and the electrode coils 7 can be loaded on both sides of the support beam 13 on the cantilever shaft 11. Multiple electrode coils 7 can be loaded on both sides of the cantilever shaft 11. In order to ensure stability, the number of electrode coils 7 on both sides should be the same.

[0035] The surface of the cantilever shaft 11 is also provided with rollers 14 that roll and arrange along its axial direction.

[0036] In the present invention, by providing the rollers 14 on the cantilever shaft 11, when the electrode coil 7 is loaded on the cantilever shaft 11, the inner wall of the electrode coil 7 contacts the rollers 14, so that the electrode coil 7 can slide on the cantilever shaft 11 with low friction. The low-friction sliding can, on the one hand, reduce the wear between the electrode coil 7 and the cantilever shaft 11, and on the other hand, ensure the smoothness of the toggling operation. Due to the action of gravity, the inner wall of the electrode coil 7 contacts the top of the outer wall of the cantilever shaft 11. Therefore, the rollers 14 can be only provided on the top of the outer wall of the cantilever shaft 11, thereby reducing the manufacturing cost.

[0037] Specifically in this embodiment, the material feeding device 4 further includes a cross beam 43 and leg frames 42 correspondingly provided on both sides. Both ends of the cross beam 43 are slidably provided on the leg frames 42. The leg frames 42 are provided with a first driving component 44 connected to the cross beam 43. The first driving component 44 is used to drive the cross beam 43 to approach or move away from the rotating station. The cross beam 43 is provided with a second driving component 45 connected to the fork 41. The second driving component 45 is used to drive the fork 41 to move back and forth along the side of the rotating station.

[0038] There are many choices for the first driving component 44 and the second driving component 45, such as cylinders, hydraulic cylinders, electric push rods, linear motors, etc. Those skilled in the art can select appropriate driving components according to needs. The driving components need to cooperate with the sliding components to achieve displacement operations. The sliding components include slide rails and sliders, and the sliders are driven by the driving components to move along the slide rails.

[0039] Such as Figure 3 As shown, when the blanking device 4 of the present invention performs blanking operations, the first driving component 44 drives the cross beam 43 close to the rotating station, so that the fork 41 reaches the side of the electrode coil 7. The second driving component 45 drives the fork 41 to move. The electrode coil 7 is pushed by the fork 41 from the electrode coil 7 on the cantilever shaft 11 of the material tray 1 at the loading side rotating station 21 to the cantilever shaft 11 of the material tray 1 at the unloading side rotating station 22. The blanking operation is stable and labor-saving.

[0040] Specifically, in this embodiment, a first conveyor line 51 is provided at both the loading side rotating station 21 and the unloading side rotating station 22. The first conveyor line 51 is used to convey the material tray 1; a notch is provided on the first conveyor line 51 for the rotating device 3 to pass through to rotate the material tray 1 on the first conveyor line 51. A loading side transfer station 23 is provided on the side of the loading side rotating station 21 away from the unloading side rotating station 22, and an unloading side transfer station 24 is provided on the side of the unloading side rotating station 22 away from the loading side rotating station 21; a second conveyor line 52 is provided at both the loading side transfer station 23 and the unloading side transfer station 24. A passage for the AGV cart 6 to pass through is provided in the middle of the second conveyor line 52. Such as Figure 4 As shown, the AGV cart 6 includes a vehicle body 62 and a lifting mechanism 61 provided on the top of the vehicle body 62. A tray fixing seat is provided on the top driving end of the lifting mechanism 61.

[0041] While solving the problem of the pole ear commutation of the electrode coil 7, the present invention realizes the transfer of the material tray 1 by setting the first conveyor line 51, the second conveyor line 52 and the AGV cart 6. The fully loaded material tray 1 is transferred by the AGV cart 6 to the channel of the second conveyor line 52 on the loading side, and then the fully loaded material tray 1 is lowered onto the second conveyor line 52 on the loading side by the lifting mechanism 61 on the AGV cart 6. After the AGV cart 6 withdraws, the second conveyor line 52 on the loading side conveys the fully loaded material tray 1 to the first conveyor line 51 on the loading side. Similarly, the empty material tray 1 is transferred by the AGV cart 6 to the channel of the second conveyor line 52 on the unloading side, and then the fully loaded material tray 1 is lowered onto the second conveyor line 52 on the unloading side by the lifting mechanism 61 on the AGV cart 6. After the AGV cart 6 withdraws, the second conveyor line 52 on the unloading side conveys the empty material tray 1 to the first conveyor line 51 on the unloading side. After the fully loaded material tray 1 and the empty material tray 1 are in place, the dialing operation is performed by the dialing device 4.

[0042] Specifically, in this embodiment, both the first conveyor line 51 and the second conveyor line 52 include a fixed frame and the unpowered rollers and powered rollers arranged on the fixed frame. The two first conveyor lines 51 and the two second conveyor lines 52 are of an integrated structure.

[0043] The present invention provides the conveying power of the first conveyor line 51 and the second conveyor line 52 through the powered rollers, and at the same time ensures the smooth conveying through the unpowered rollers. The powered rollers at each working station can be independently controlled to realize flexible conveying operations. Through the integrated structure of the first conveyor line 51 and the second conveyor line 52, the connection between the first conveyor line 51 and the second conveyor line 52 is tight, which can not only ensure the stability of the overall structure of the conveyor line, but also ensure the stability of conveying.

[0044] Specifically, in this embodiment, the rotating device 3 includes a lifting component, a rotating motor and a rotating table. An electric motor fixing seat is arranged on the top driving end of the lifting component, the rotating motor is arranged on the electrode fixing seat, and the main shaft of the rotating motor passes upward through the fixing flange and is connected to the middle part of the rotating table.

[0045] By setting the rotating device 3 with a lifting component, the present invention can rotate the material tray 1 on the first conveyor line 51 in the lifting state through the notch on the first conveyor line 51, so as to integrate the conveying operation and the rotating operation, making the overall structure more compact and with high integration.

[0046] Specifically, in this embodiment, photoelectric sensors are arranged at the loading side rotating station 21, the unloading side rotating station 22, the loading side transfer station 23 and the unloading side transfer station 24, and the photoelectric sensors are used to detect the material tray 1.

[0047] By providing a photoelectric sensor, the present invention can detect whether the material tray 1 reaches the feeding-side rotation station 21, the discharging-side rotation station 22, the feeding-side transfer station 23, and the discharging-side transfer station 24. After obtaining the detection signal, it can perform automatic control according to the detection signal, thereby improving the degree of automation.

[0048] In summary, the working process of an electrode roll 7 ear commutation device provided by the present invention is as follows: (1) After the slitting equipment discharges the slit material roll onto the material tray 1 through the discharging mechanism, the fixed slitting equipment shaft will produce a pole roll with the wrong ear direction. The AGV cart 6 moves to the designated position, picks up the material tray 1 full of electrode rolls 7 with different ear directions, transports it to the front side of the feeding-side transfer station 23, lifts the material tray 1 through the lifting mechanism 61 and enters the feeding-side transfer station 23. After putting down the material tray 1, it exits and returns to the discharging area of the slitting equipment to wait for the next task.

[0049] (2) The second conveyor line 52 on the feeding-side transfer station 23 starts to rotate. The full material tray 1 moves along with the rollers to the feeding-side rotation station 21. After the photoelectric sensor detects the material tray 1, the rollers stop rotating. The full material tray 1 stops at the designated position of the feeding-side rotation station 21, and the cantilever shaft 11 is aligned with the cantilever shaft 11 of the empty material tray 1 at the discharging-side rotation station 22.

[0050] (3) After receiving the signal, the first driving component 44 of the material shifting equipment 4 drives the cross beam 43 to move towards the rotation station until the material fork 41 reaches the edge of the reel of the electrode roll 7, and then the first driving component 44 stops driving; the second driving component 45 drives the material fork 41 to shift the electrode roll 7, so that the electrode roll 7 on a single cantilever shaft 11 slides onto the cantilever shaft 11 of the empty material tray 1 at the discharging-side rotation station 22, realizing the ear commutation of the electrode roll 7 on this cantilever shaft 11; after completion, the first driving component 44, the second driving component 45, and the material fork 41 return to their original positions.

[0051] (4) The rotating equipment 3 at the feeding-side rotation station 21 lifts the material tray 1 with the electrode roll 7 with half of the ear directions different to the safe position and then rotates it by 180 degrees, so that the cantilever shaft 11 with the electrode roll 7 on the other side of the material tray 1 faces the cantilever shaft 11 of the material tray 1 at the discharging-side rotation station 22. After rotation, the rotating equipment 3 descends; similarly, the material tray 1 at the discharging-side rotation station 22 is rotated by 180 degrees, and then the material shifting process in step (3) is repeated; all the electrode rolls 7 on the material tray 1 at the feeding-side rotation station 21 are transferred to the material tray 1 at the discharging-side rotation station 22, completing the commutation action.

[0052] (5) The rollers of the second conveyor line 52 on the blanking side rotation station 22 rotate, driving the material tray 1 to the blanking side transfer station 24. The AGV cart 6 receives the signal, picks up the material tray 1 that has completed the tab commutation at the blanking side transfer station 24, and transports it to the downstream process.

[0053] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
