The feeding mechanism 3 is used to output the workpiece unrolled by the material unrolling mechanism 1 to the flattening mechanism 2 and transport the workpiece flattened by the flattening mechanism 2 to the next station.

[0026] Please review Figure 1 As shown in the figure, the material unfolding mechanism 1 includes a supporting drive component 11, a coil clamping component 12, a coil unwinding component 13 and a material unloading base 14.

The coil unwinding component 13 is used to unfold the rolled workpiece clamped by the coil clamping component 12.

[0027] See also Figure 2 and 3 , Figure 2 It is a structural schematic diagram of the material spreading mechanism of the material unloading device of this embodiment; Figure 3 for Figure 2A schematic diagram of the structure in another direction. As shown in the figure, the supporting drive assembly 11 includes a supporting drive group 111 and a supporting transmission group 112. The supporting drive group 111 is used to drive the supporting transmission group 112, and the supporting transmission group 112 is used to drive the coil clamping assembly 12 to move closer to or away from the coil shaft. The supporting drive group 111 is arranged on the unloading base 14. The supporting drive group 111 can adopt a driving motor or a driving cylinder; when the supporting drive group 111 adopts a driving motor, the supporting transmission group 112 adopts a driving screw and a screw nut. The driving screw is connected to the output end of the driving motor, and the coil clamping assembly 12 is slidably connected to the driving screw through the screw nut. When the driving motor is started, the driving screw rotates with the output end of the driving motor, and the coil clamping assembly 12 slides along the driving screw with the screw nut, moving closer to or away from the coil shaft. In this embodiment, the holding drive group 111 uses a driving cylinder, the holding transmission group 112 is connected to the output end of the driving cylinder, and the coil clamping assembly 12 is connected to the holding transmission group 112. When unloading from the coil shaft, the driving cylinder is started, and the holding transmission group 112 drives the coil clamping assembly 12 to approach the coil shaft, and the coil clamping assembly 12 holds the workpiece on the coil shaft, and then the coil unwinding assembly 13 unfolds the workpiece held by the coil clamping assembly 12, so that the workpiece is unloaded from the coil shaft.

[0028] Please review Figure 2 and 3 As shown in the figure, the support transmission group 112 includes a transmission plate 1121 and a connecting member 1122. The transmission plate 1121 is connected to the output end of the support driving group 111, the connecting member 1122 is connected to the transmission plate 1121, and the coil clamping assembly 12 is arranged on the connecting member 1122. When the support driving group 111 is started, the transmission plate 1121 moves with the output end of the clamping driving member, the transmission plate 1121 drives the connecting member 1122 to move, and the coil clamping assembly 12 arranged on the connecting member 1122 moves with the connecting member 1122.

[0029] Please review Figure 2 As shown in the figure, in this embodiment, the clamping transmission group 112 also includes an adjustment group, which includes an adjustment seat 1123 and an adjustment block 1124. The adjustment seat 1123 is connected to the transmission plate 1121, and the adjustment block 1124 is connected to the connecting member 1122. The adjustment block 1124 is adjustably arranged on the adjustment seat 1123. The position of the adjustment block 1124 in the adjustment seat 1123 can be adjusted according to the width of the rolled workpiece, thereby further adjusting the movement stroke of the holding drive assembly 11 to drive the coil clamping assembly 12 to the coil shaft.

[0030] Please review Figure 2 and 3As shown in the figure, the coil material holding assembly 12 includes a first coil material holding group 12a and a second coil material holding group 12b, which are respectively used to hold the coiled workpiece from both sides of the coiled workpiece interface. The first coil material holding group 12a and the second coil material holding group 12b are arranged on both sides of the connecting member 1122, and the first coil material holding group 12a and the second coil material holding group 12b can move toward the coil material axis with the connecting member 1122, and can also move relatively along the connecting member 1122. When unloading from the coil shaft, the holding drive group 111 drives the holding transmission group 112 to approach the coil shaft, and the holding transmission group 112 drives the first coil holding group 12a and the second coil holding group 12b to approach the coil shaft at the same time. The first coil holding group 12a and the second coil holding group 12b respectively hold the rolled workpiece from both sides of the rolled workpiece interface. Afterwards, the coil unfolding component 13 makes the first coil holding group 12a and the second coil holding group 12b move away from each other along the connecting piece 1122 and unfold the held workpiece, so that the workpiece is unloaded from the coil shaft.

[0031] Please review Figure 2 As shown in the figure, the first coil holding group 12a includes a clamping slide 121 and a clamp group 122. The clamping slide 121 is arranged on the connecting member 1122, and the clamp group 122 is arranged on the clamping slide 121. When the holding drive group 111 drives the holding transmission group 112 to approach the coil shaft, the clamping slide 121 approaches the coil shaft along with the connecting member 1122, and the clamp group 122 approaches the coil shaft along with the clamping slide 121 and clamps the rolled workpiece on the coil shaft.

[0032] Please review Figure 2 As shown in the figure, the clamp group 122 includes a fixed clamp 1221, a movable clamp driving member 1222 and a movable clamp 1223. The fixed clamp 1221 and the movable clamp driving member 1222 are arranged on the clamping slide 121, and the movable clamp 1223 is connected to the driving end of the movable clamp driving member 1222. In this embodiment, the movable clamp driving member 1222 adopts a driving cylinder. When clamping the workpiece on the coil shaft, the fixed clamp 1221 extends into the inside of the coiled workpiece, and then the movable clamp driving member 1222 drives the movable clamp 1223 to approach the fixed clamp 1221, and the fixed clamp 1221 and the movable clamp 1223 clamp the coiled workpiece from the inside and outside of the coiled workpiece respectively.

[0033] The structure and function of the second coil holding group 12b are the same as those of the first coil holding group 12a, and will not be described again here.

[0034] Please review Figure 2As shown in the figure, when the holding drive assembly 11 drives the coil clamping assembly 12 to approach the coil shaft, in order to ensure the linearity and stability of the movement of the coil clamping assembly 12, an adjustment slide rail 141 is provided on the unloading bottom plate 14, and the clamping slide 121 of the first coil holding group 12a and the second coil holding group 12b is slidably connected to the adjustment slide rail 141. When the holding drive assembly 11 drives the coil clamping assembly 12 to approach the coil shaft, the clamping slide 121 slides along the adjustment slide rail 141.

[0035] Please review Figure 2 and 3 As shown in the figure, in order to make the rolled workpiece on the coil shaft to be evenly unfolded, in this embodiment, the number of the holding drive assembly 11 and the coil clamping assembly 12 is two, and the two holding drive assemblies 11 and the coil clamping assembly 12 are symmetrically arranged at both ends of the unloading base 14, and each holding drive assembly 11 drives a coil clamping assembly 12. The first coil holding group 12a of one coil clamping assembly 12 is arranged opposite to the first coil holding group 12a of another coil clamping assembly 12, and the second coil holding group 12b of one coil clamping assembly 12 is arranged opposite to the second coil holding group 12b of another coil clamping assembly 12. When unloading, the two holding drive components 11 drive the two coil material clamping components 12 to approach the coil material shaft at the same time, and the two first coil material holding groups 12a hold the coiled workpiece from both ends of one side of the coiled workpiece interface, and the two second coil material holding groups 12b hold the coiled workpiece from both ends of the other side of the coiled workpiece interface, and then the coil material unwinding component 13 is started to unwind the coiled workpiece. Both sides of the unwinding workpiece are clamped by the first coil material holding group 12a and the second coil material holding group 12b of the coil material clamping component 12 at the same time, and both sides of the workpiece are subjected to force at the same time, so that the unwinding is more uniform.

[0036] Please review Figure 2 and 3As shown in the figure, the coil unwinding assembly 13 includes an unwinding actuator 131 and an unwinding transmission member 132. The unwinding actuator 131 is used to drive the unwinding transmission member 132. The unwinding transmission member 132 is used to drive the first coil holding group 12a and the second coil holding group 12b to slide along the connecting member 1122 and move away from each other to unwind the coiled workpiece. When the holding drive assembly 11 drives the coil clamping assembly 12 to approach the coil shaft and clamp the workpiece, the unwinding actuator 131 drives the unwinding transmission member 132 to move, and the unwinding transmission member 132 drives the first coil holding group 12a and the second coil holding group 12b to move away from each other to unwind the coiled workpiece. The unfolding actuator 131 can be driven by a cylinder or a motor; when a cylinder is used, a bidirectional cylinder can be used to simultaneously connect the first coil holding group 12a and the second coil holding group 12b. At this time, the unfolding transmission member 132 can be a common linkage member, or two cylinders can be used to drive the first coil holding group 12a and the second coil holding group 12b respectively. In this embodiment, the unfolding actuator 131 is driven by a motor, and the unfolding actuator 131 includes an unfolding drive motor 1311 and an unfolding drive gear 1312. The unfolding transmission member 132 uses a transmission rack, and the number of transmission racks is two; the unfolding drive motor 1311 is arranged on the unloading bottom plate 14, and the unfolding drive gear 1312 is connected to the output end of the unfolding drive motor 1311 and meshes with the unfolding transmission member 132, and each adjustment slide rail 141 is arranged on an unfolding transmission member 132. When the unfolding drive motor 1311 is started, the unfolding drive gear 1312 rotates with the output end of the unfolding drive motor 1311, and the unfolding drive gear 1312 rotates along the two transmission racks, and the adjustment slide rails 141 connected to the two transmission racks move away from each other, thereby driving the first coil holding group 12a and the second coil holding group 12b to move away from each other to unfold the rolled workpiece on the coil shaft. After the workpiece is unfolded, the coil unfolding assembly 13 drives the first coil holding group 12a and the second coil holding group 12b to reset.

[0037] Please review Figure 2 As shown in the figure, in this embodiment, an unfolding slide rail 142 is provided on the material unloading bottom plate 14, and an adjusting slider 1411 is provided at the bottom of the adjusting slide rail 141, and the adjusting slider 1411 is slidably connected to the unfolding slide rail 142. When the coil unfolding assembly 13 drives the first coil holding group 12a and the second coil holding group 12b to move away from each other, the adjusting slider 1411 moves along the unfolding slide rail 142, which can ensure the stability and linearity of the movement of the first coil holding group 12a and the second coil holding group 12b when unfolding the workpiece.

[0038] Since the workpiece is wound on the coil shaft, when the first coil holding group 12a and the second coil holding group 12b release the workpiece, the workpiece will curl due to internal stress, which is not conducive to production. In order to keep the workpiece flat after unloading, the flattening and unrolling mechanism 1 of the unloading device of the present application unfolds the workpiece, and the unfolded workpiece is transported to the flattening mechanism 2 for flattening.

[0039] See also Figure 4 and 5 , Figure 4 It is a structural schematic diagram of the flattening mechanism of the blanking device of the present invention; Figure 5 for Figure 4 Structural diagram of another direction. As shown in the figure, the flattening mechanism 2 includes a flattening moving component 21 and a flattening component 22. The flattening moving component 21 is used to drive the flattening component 22 to approach the workpiece, and the flattening component 22 is used to flatten the workpiece unfolded by the material spreading mechanism 1. When the material spreading mechanism 1 unloads the workpiece from the coil shaft, the flattening moving component 21 drives the flattening component 22 to approach the workpiece and flatten the workpiece.

[0040] Please review Figure 5 As shown in the figure, the flattening moving assembly 21 includes a flattening frame 211, a flattening moving driving member 212 and a flattening moving transmission member 213. The flattening moving driving member 212 is arranged on the flattening frame 211, the flattening moving transmission member 213 is connected to the output end of the flattening moving driving member 212, and the flattening assembly 22 is connected to the flattening moving transmission member 213. When the flattening moving driving member 212 is started, the flattening moving transmission member 213 moves with the flattening moving driving member 212 and drives the flattening assembly 22 to approach or move away from the unfolded workpiece. The flattening moving driving member 212 can adopt a driving cylinder or a driving motor. When the driving cylinder is adopted, the flattening moving transmission member 213 is connected to the output end of the driving cylinder, and the flattening moving transmission member 213 is driven to move by the extension and contraction of the cylinder column, thereby driving the flattening assembly 22 to approach or move away from the unfolded workpiece. In this embodiment, the flattening moving driving member 212 adopts a driving motor, and the flattening moving transmission member 213 adopts a transmission screw, which is connected to the output end of the driving motor, and the flattening assembly 22 is slidably connected to the transmission screw through a screw nut. When the driving motor is started, the transmission screw rotates with the output end of the driving motor and drives the flattening assembly 22 to slide along the transmission screw.

[0041] Please review Figure 4 and 5As shown in the figure, the flattening assembly 22 includes a flattening connecting plate 221, a flattening driving member 222, an upper pressing plate 223 and a lower pressing plate 224. The flattening connecting plate 221 is connected to the flattening moving transmission member 213 through a screw nut. The flattening driving member 222 is arranged on the flattening connecting plate 221. The upper pressing plate 223 and the lower pressing plate 224 are connected to the output end of the flattening driving member 222. Before the flattening moving assembly 21 drives the flattening assembly 22 to approach the unfolded workpiece, the flattening driving member 222 drives the upper pressing plate 223 and the lower pressing plate 224 to separate from each other. After the flattening moving assembly 21 drives the flattening assembly 22 to approach the unfolded workpiece, the upper pressing plate 223 and the lower pressing plate 224 are respectively located above and below the unfolded workpiece. Then, the flattening driving member 222 drives the upper pressing plate 223 and the lower pressing plate 224 to approach each other and flatten the workpiece located between the upper pressing plate 223 and the lower pressing plate 224. The flattening drive member 222 can be a drive motor or a drive cylinder. When a drive motor is used, the drive motor is connected to a drive screw, and the threads on both sides of the drive screw are opposite. The upper pressure plate 223 and the lower pressure plate 224 are slidably connected to the two ends of the drive screw through the screw nut. When the drive motor is started, the upper pressure plate 223 and the lower pressure plate 224 move closer to or away from each other along the drive screw. In this embodiment, the flattening drive member 222 uses a bidirectional drive cylinder, and the upper pressure plate 223 and the lower pressure plate 224 are respectively connected to the two execution ends of the bidirectional drive cylinder, and the bidirectional drive cylinder drives the upper pressure plate 223 and the lower pressure plate 224 to move closer to or away from each other.

[0042] Please review Figure 4 and 5 As shown in the figure, in order to make the flattening component 22 move smoothly, a flattening movable slide rail 2111 is provided on the flattening frame 211, and a flattening movable slider 2211 is provided on the flattening connecting plate 221. The flattening movable slider 2211 is slidably connected to the flattening movable slide rail 2111. When the flattening movable component 21 drives the flattening component 22 to approach the unfolded workpiece, the flattening movable slider 2211 moves along the flattening movable slide rail 2111, which can ensure the linearity and smoothness of the movement.

[0043] Please review Figure 4 and 5As shown in the figure, in this embodiment, the upper pressing plate 223 includes a pressing plate connecting plate 2231 and a plurality of pressing plates 2232, the pressing plate connecting plate 2231 is connected to the driving end of the flattening driving member 222, and the plurality of pressing plates 2232 are evenly distributed on the pressing plate connecting plate 2231 along the width direction of the pressing plate connecting plate 2231, and a spacing is provided between adjacent pressing plates 2232. The lower pressing plate 224 includes a connecting portion 2241 and a plurality of suction plates 2242, one end of the plurality of suction plates 2242 is connected to the connecting portion 2241 and evenly distributed on the connecting portion 2241 along the length direction of the connecting portion 2241, and the spacing between adjacent suction plates 2242 is the same. When the upper pressing plate 223 and the lower pressing plate 224 flatten the unfolded workpiece, the plurality of pressing plates 2232 act on the workpiece along the width direction of the unfolded workpiece, and the plurality of suction plates 2242 act on the workpiece from the length direction of the unfolded workpiece, so that the workpiece is unfolded evenly.

[0044] Please review Figure 4 As shown in the figure, when the flattening assembly 22 flattens the unfolded workpiece, in order to prevent the flattening assembly 22 from crushing the workpiece, the flattening assembly 22 of this embodiment also includes a buffer 225, and the buffer 225 is arranged on the upper pressing plate 223; when the upper pressing plate 223 and the lower pressing plate 224 flatten the workpiece, the buffer 225 can buffer the pressure of the pressing plate assembly on the workpiece, so that the upper pressing plate 223 is in flexible contact with the workpiece, thereby protecting the workpiece.

[0045] Please review Figure 4 As shown in the figure, in this embodiment, one end of the buffer 225 is connected to the pressing plate connecting plate 2231, and the other end of the buffer 225 is connected to the pressing plate 2232. When the pressing plate 2232 and the suction plate 2242 interact with each other, the buffer 225 can buffer the pressure of the pressing plate 2232 and the suction plate 2242 on the workpiece. The buffer 225 of this embodiment can be a spring, or a workpiece with elastic materials such as a rubber column.

[0046] Please review Figure 5 As shown in the figure, when the flattening assembly 22 flattens the unfolded workpiece, in order to prevent the workpiece from shifting, a first suction nozzle 2243 is provided on the lower pressing plate 224, and the first suction nozzle 2243 is provided on the suction plate 2242. The first suction nozzle 2243 is connected to the air pump when in use. After the unfolded workpiece is located between the upper pressing plate 223 and the lower pressing plate 224, the external air pump draws air through the first suction nozzle 2243, so that the workpiece is sucked by the first suction nozzle 2243.

[0047] When the upper pressing plate 223 and the lower pressing plate 224 press the workpiece flat, if the upper pressing plate 223 and the lower pressing plate 224 press the workpiece into place at once, the curled part of the workpiece may not have time to unfold. In order to make the curled part of the workpiece unfold completely when the flattening assembly 22 presses the workpiece flat, please review Figure 4As shown in the figure, the flattening mechanism 2 also includes a pre-pressing component 23, which is used to enable the flattening component 22 to pre-press the workpiece before flattening it.

[0048] Please review Figure 4 As shown in the figure, in this embodiment, the pre-pressing assembly 23 includes a pre-pressing driving member 231 and a pre-pressing limiting member 232. The pre-pressing driving member 231 is arranged on the flattening connecting plate 221, and the pre-pressing limiting member 232 is arranged on the connecting portion 2241. The execution end of the pre-pressing driving member 231 is aligned with the pre-pressing limiting member 232. When the flattening driving member 222 drives the upper pressing plate 223 and the lower pressing plate 224 to approach each other, the connecting portion 2241 moves upward and drives the pre-pressing limiting member 232 to move toward the pre-pressing driving member 231. When the pre-pressing limiting member 232 contacts the pre-pressing driving member 231, the upper pressing plate 223 and the lower pressing plate 224 complete the pre-pressing of the unfolded workpiece; then the execution end of the pre-pressing driving member 231 is recovered, and when the flattening driving member 222 drives the upper pressing plate 223 and the lower pressing plate 224 to approach each other again, the unfolded workpiece is flattened. In this embodiment, the pre-pressing driving member 231 adopts a driving cylinder. Before pre-pressing the workpiece, the cylinder column of the driving cylinder extends out, and after pre-pressing the workpiece, the cylinder column of the driving cylinder retracts, so that the flattening driving member 222 drives the upper pressure plate 223 and the lower pressure plate 224 to approach each other again to flatten the unfolded workpiece.

[0049] After the flattening mechanism 2 flattens the unfolded workpiece, the flattened workpiece can be put into production. If the flattening moving component 21 of the flattening mechanism 2 directly drives the flattening component 22 to move and output the workpiece, when the material spreading mechanism 1 unfolds the workpiece, the flattening mechanism 2 will not have enough time to flatten the workpiece, which will affect the working efficiency of the unloading device.

[0050] In order to output the flattened workpiece without affecting the unloading efficiency of the unloading device, the feeding mechanism 3 of the unloading device of this embodiment is used to convey the workpiece unfolded by the spreading mechanism 1 to the flattening mechanism 2. After the spreading mechanism 1 unfolds the workpiece and unloads it from the unloading shaft, the feeding mechanism 3 conveys the spreading mechanism 1 to the flattening mechanism 2. While the flattening mechanism 2 flattens the workpiece, the spreading mechanism 1 releases the workpiece, allowing the workpiece to enter the flattening mechanism 2, and then the spreading mechanism 1 resets. After the flattening mechanism 2 flattens the workpiece, the workpiece is output.

[0051] Please review Figure 1 As shown in the figure, the feeding mechanism 3 includes a feeding conveying assembly 31, which is used to convey the material spreading mechanism 1 to the flattening mechanism 2. After the material spreading mechanism 1 unfolds the workpiece on the coiling shaft and unloads the workpiece from the coiling shaft, the conveying assembly 31 conveys the material spreading mechanism 1 to the flattening mechanism.

[0052] Please review Figure 1As shown in the figure, in order to further improve the material discharging efficiency of the material discharging device, the feeding mechanism 3 of this embodiment also includes a material picking assembly 32, and the material picking assembly 32 is used to take out the workpiece flattened by the flattening mechanism 2. The material picking assembly 32 is slidably connected to the feeding conveying assembly 31. When the feeding conveying assembly 31 conveys the material spreading mechanism 1 to the flattening mechanism 2, the material picking assembly 32 is conveyed from the flattening mechanism 2 to the next station by the feeding conveying assembly 31. The feeding conveying assembly 31 can alternately convey the material spreading mechanism 1 and the material picking assembly 32 to the flattening mechanism 2. When the feeding conveying assembly 31 conveys the material spreading mechanism 1 to the flattening mechanism 2, the flattening mechanism 2 takes the unfolded workpiece from the material spreading mechanism 1 and flattens it. When the feeding conveying assembly 31 conveys the material picking assembly 32 to the flattening mechanism 2, the flattening mechanism 2 conveys the flattened workpiece to the material picking assembly 32. In this embodiment, a fixed seat 33 is provided between the material spreading mechanism 1 and the material picking assembly 32, and the fixed seat 33 is connected to the feeding conveying assembly 31.

[0053] The feeding and conveying component 31 can adopt a divider driven by a motor, and the fixed seat 33 is a turntable connected to the output end of the divider. When the feeding and conveying component 31 causes the material spreading mechanism 1 to leave the flattening mechanism 2, the material picking component 32 is transported to the flattening mechanism 2. When the material picking component 32 carries the flattened workpiece and is output from the flattening mechanism 2 by the divider, the material spreading mechanism 1 is transported to the flattening mechanism 2; the material spreading mechanism 1, the flattening mechanism 2 and the material picking component 32 can perform different actions synchronously, which can improve the unloading efficiency of the unloading device.

[0054] Please review Figure 1 As shown in the figure, in this embodiment, the feeding and conveying assembly 31 adopts a robot, the flattening mechanism 2 is arranged in the moving direction of the fixed seat 33, the material spreading mechanism 1 and the material picking assembly 32 are arranged at both ends of the fixed seat 33, when the feeding and conveying assembly 31 moves the material spreading mechanism 1 to the flattening mechanism 2, the material picking assembly 32 is lowered by one station, and the flattened workpiece is transported to the assembly station, when the material spreading mechanism 1 is reset, the material picking assembly 32 is transported to the flattening mechanism 2, and the cycle is repeated in sequence.

[0055] Please review Figure 1 As shown in the figure, in this embodiment, the material taking component 32 includes a bearing connection member 321 and a plurality of bearing plates 322. The bearing connection member 321 is connected to the fixing seat 33. One end of the plurality of bearing plates 322 is connected to the bearing connection member 321 and is evenly distributed on the bearing connection member 321. The direction of the bearing connection plate 321 is consistent with the direction of the suction plate 2242, and they are staggered. When the material taking component 32 moves to the flattening mechanism 2, the plurality of bearing plates 322 just enter the gap between the plurality of suction plates 2242, so that the flattened workpiece is carried by the bearing plate 322, and then the flattening moving component 21 drives the flattening component 22 to retreat, leaving the flattened workpiece on the bearing plate 322.

[0056] Please review Figure 1 As shown in the figure, in this embodiment, a second suction nozzle 3221 is provided on the carrying plate 322. When the feeding conveying assembly 31 drives the material picking assembly 32 to leave the flattening mechanism 2, the external air pump draws air through the second suction nozzle 3221 to absorb the flattened workpiece to prevent the flattened workpiece from falling during the conveying process.

[0057] In this embodiment, the material spreading mechanism 1, the flattening mechanism 2 and the feeding mechanism 3 are electrically connected to the control system of the material unloading device, and the control system of the material unloading device controls the movement of the material spreading mechanism 1, the flattening mechanism 2 and the feeding mechanism 3 to achieve the effect of automatic control of the material unloading device.

[0058] The following takes unloading of battery cells from a winding shaft as an example to specifically describe the working principle of the unloading device of this embodiment:

[0059] After the coil shaft with the battery cell wound around it is transported to the unwinding mechanism 1 and aligned with the coil clamping assembly 12, the coil unwinding assembly 13 is started, the unwinding actuator 131 is started, and the unwinding transmission member 132 is driven to move, and the adjusting slider 1411 at the bottom of the adjusting slide rail 141 moves along the unwinding slide rail 142, so that the first coil holding group 12a and the second coil holding group 12b arranged on the adjusting slide rail 141 are close to each other, so that the distance between the first coil holding group 12a and the second coil holding group 12b is not greater than the diameter of the rolled battery cell; then the two holding drive assemblies 11 drive the two coil clamping assemblies 12 to approach the coil shaft at the same time, and when the fixed clamp 1221 extends into the rolled battery cell, the holding drive assembly 11 stops moving, and the movable clamp driving member 1222 drives the movable clamp 1223 to approach the fixed clamp 1221 and clamp the battery cell. At this time, the two first coil holding groups 12a hold the rolled battery cells from both ends of one side of the rolled battery cell interface, and the two second coil holding groups 12b hold the rolled battery cells from both ends of the other side of the rolled battery cell interface. Then the coil unwinding assembly 13 is started, and when the unwinding drive motor 1311 is started, the unwinding drive gear 1312 rotates with the output end of the unwinding drive motor 1311, and the unwinding drive gear 1312 rotates along the two transmission racks, and the adjustment slide rails 141 connected to the two transmission racks move away from each other, and the adjustment slider 1411 moves along the unwinding slide rail 142, thereby driving the first coil holding group 12a and the second coil holding group 12b to move away from each other to unwind the rolled battery cells on the coil shaft.

[0060] Afterwards, the feeding mechanism 3 is started, and when the feeding conveying assembly 31 conveys the material spreading mechanism 1 to the flattening mechanism 2, the flattening moving assembly 21 drives the flattening assembly 22 to approach the unfolded battery cell. At this time, the upper pressing plate 223 and the lower pressing plate 224 are separated from each other. When the flattening moving assembly 21 drives the flattening assembly 22 to approach the unfolded battery cell, the upper pressing plate 223 and the lower pressing plate 224 are respectively located above and below the unfolded battery cell. Then, the flattening driving member 222 drives the upper pressing plate 223 and the lower pressing plate 224 approach each other, the connecting part 2241 moves upward, and drives the pre-pressing limiter 232 to move toward the pre-pressing driving member 231. When the pre-pressing limiter 232 contacts the pre-pressing driving member 231, the upper pressing plate 223 and the lower pressing plate 224 complete the pre-pressing of the unfolded battery cell, and the coil clamping assembly 12 releases the battery cell. Then, the external air pump draws air through the first suction nozzle 2243, so that the battery cell is adsorbed on the suction plate 2242 by the first suction nozzle 2243. After that, the execution end of the pre-pressing driving member 231 is recovered, and when the flattening driving member 222 drives the upper pressing plate 223 and the lower pressing plate 224 to approach each other again, the unfolded battery cell is flattened.

[0061] After the flattening component 22 flattens the battery cell, the flattening moving component 21 drives the flattening component 22 to move back with the flattened battery cell, and the feeding and conveying component 31 drives the material spreading mechanism 1 to reset, and at the same time conveys the material taking component 32 to the flattening mechanism 2.

[0062] When the material spreading mechanism 1 is reset, the material picking assembly 32 is aligned with the flattening mechanism 2, and the flattening moving assembly 21 drives the flattening assembly 22 to bring the flattened battery cells closer to the material picking assembly 32, and the plurality of carrier plates 322 just enter the gaps between the plurality of suction plates 2242, so that the flattened battery cells are carried by the carrier plates 322, and the first suction nozzle 2243 stops sucking the battery cells, while the second suction nozzle 3221 starts sucking the battery cells. Then the flattening moving assembly 21 drives the flattening assembly 22 to retreat, leaving the flattened battery cells on the carrier plates 322.

[0063] Afterwards, the feeding and conveying assembly 31 conveys the material spreading mechanism 1 to the flattening mechanism 2, and at the same time, the material taking assembly 32 takes the battery cell away from the flattening mechanism 2 and conveys the battery cell to the next station. The cycle continues.
