As shown in fig. 1, a feeding device 100 provided in an embodiment of the present application includes a driving member 110, a clamping assembly 120, and a cutting assembly 130.

The driving member 110 is connected to the clamping assembly 120 and the cutting assembly 130 to drive the clamping assembly 120 and the cutting assembly 130 to move synchronously along the conveying direction of the material web 20.

A severing assembly 130 is downstream of the clamping assembly 120 for severing the web 20 (see fig. 3). The nip assembly 120 includes a first nip roller 122, a second nip roller 123, and a feed drive 124. The first pinch roller 122 and the second pinch roller 123 can be moved toward and away from each other to pinch or release the web 20. The feeding drive 124 can drive at least one of the first pinch roller 122 and the second pinch roller 123 to rotate to convey the pinched web downstream.

The conveying direction of the tape 20 is the X direction in fig. 1. In addition, in the present embodiment, the material tape 20 is a pole piece material tape.

First, the driving member 110 drives the clamp assembly 120 and the cutter assembly 130 to move in the conveying direction of the web 20, and makes the moving speed of the clamp assembly 120 and the cutter assembly 130 the same as the conveying speed of the web 20. Next, the first pinch roller 122 and the second pinch roller 123 are brought close to each other to pinch the web 20, and then the cutting assembly 130 cuts the web 20. After the web 20 is cut, the driving member 110 is stopped, and the feeding driving member 124 drives at least one of the first pinch roller 122 and the second pinch roller 123 to rotate to continue conveying the clamped web 20 downstream until the web 20 is conveyed to a downstream mechanism. The web 20 continues to be transported by downstream mechanisms. The first nip roller 122 and the second nip roller 123 are then moved away from each other to release the web 20. Finally, the driver 110 drives the clamping assembly 120 and the severing assembly 130 back to the original positions.

With the feeding device 100, since the clamping assembly 120 and the cutting assembly 130 are connected with the driving member 110, the driving member 110 can drive the clamping assembly 120 and the cutting assembly 130 to move synchronously until the conveying speed of the material belt 20 is the same. The clamping assembly 120 then clamps the web 20 and the severing assembly 130 then severs the web 20. The feed drive 124 in the gripper assembly 120 then acts to transport the web 20 downstream. In this way, the clamping assembly 120 and the cutting assembly 130 only need one driving member 110 to drive, so that the structure is more compact and the equipment cost is low.

In addition, since one driving member 110 is provided, it is ensured that the speed at which the clamping assembly 120 and the cutting assembly 130 move in the conveying direction of the web 20 is the same. The control mode of one driving member 110 is simpler than the existing two moving members, thereby being more convenient to control.

Alternatively, the drive 110 is a servo motor or an electric cylinder and the feed drive 124 is a motor. Of course, in other embodiments, the drive member 110 and the feed drive member 124 can be other drive configurations.

In some embodiments, the loading apparatus 100 further includes a transfer plate 140. The driving member 110 is in driving connection with the transfer plate 140 to drive the transfer plate 140 to move along the conveying direction of the material belt 20. The clamping assembly 120 and the cutting assembly 130 are both disposed on the transfer plate 140 to move synchronously with the transfer plate 140 along the conveying direction of the material belt 20.

In some embodiments, the clamping assembly 120 further includes a mounting plate 121. The driving member 110 is connected to the mounting plate 121 to drive the mounting plate 121 to move in the conveying direction of the material tape 20. The first pinch roller 122 and the second pinch roller 123 are oppositely disposed to the mounting plate 121.

It will be appreciated that in the embodiment shown in fig. 1, the mounting plate 121 is mounted to the transfer plate 140.

In the embodiment shown in fig. 2, the feeding driving member 124 is disposed on the mounting plate 121 and is in transmission connection with the second nip roller 123 to drive the second nip roller 123 to rotate. Of course, in other embodiments, the feeding driving member 124 may be in transmission connection with the first clamping roller 122, or in transmission connection with the first clamping roller 122 and the second clamping roller 123, which is not limited herein.

In a first embodiment, the clamping assembly 120 includes a moving plate 125. The moving plate 125 is movably disposed on the mounting plate 121. The first pinch roller 122 is rotatably disposed on the moving plate 125 about its own axis to approach or separate from the second pinch roller 123 during movement with the moving plate 125.

Further, the clamping assembly 120 also includes a clamping drive 126. The clamping driving member 126 is disposed on the mounting plate 121 and is in driving connection with the moving plate 125 to drive the moving plate 125 to move.

In particular, in fig. 2, the clamping driving member 126 is configured to drive the moving plate 125 to move in a direction perpendicular to the material belt 20, i.e., in the Y direction in the drawing.

In the second embodiment, the clamping assembly 120 includes two clamping drives 126 and two moving plates 125. The two clamping driving members 126 and the two moving plates 125 are disposed on the mounting plate 121, and the two moving plates 125 are disposed opposite to each other. The two clamping driving members 126 are respectively connected with the two moving plates 125 in a transmission manner so as to respectively drive the two moving plates 125 to move. The first and second pinch rollers 122 and 123 are rotatably provided to the two moving plates 125 about their own axes, respectively, to approach or separate from each other in the process of moving with the moving plates 125. In this way, when the material belt 20 passes through the intermediate position between the first clamping roller 122 and the second clamping roller 123, the first clamping roller 122 and the second clamping roller 123 are both movable, so that the first clamping roller 122 and the second clamping roller 123 can be ensured to clamp the material belt 20 at the intermediate position, and the material belt 20 can be prevented from shaking during the process of clamping the material belt 20 by the first clamping roller 122 and the second clamping roller 132.

As can be seen from the above embodiments, the feeding driving member 124 is not operated after the clamping driving member 126 drives the first clamping roller 122 and the second clamping roller 123 to approach each other and clamp the material belt 20. The cutting assembly 130 cuts the material belt, and the feeding driving member 124 drives the first clamping roller 122 and/or the second clamping roller 123 to rotate, so that friction force is generated between the first clamping roller 122 and/or the second clamping roller 123 and the material belt 20 during rotation, and the material belt 20 is conveyed downstream under the action of the friction force. Finally, after the web 20 is conveyed to the downstream mechanism, the nip drive 126 drives the first nip roller 122 and the second nip roller 123 away from each other to release the web 20.

In addition, in the first embodiment, the grip driving member 126 drives the first grip roller 122 to move so as to achieve the first grip roller 122 and the second grip roller 123 to be moved toward or away from each other; in the second embodiment, both the first pinch roller 122 and the second pinch roller 123 are movable to achieve the first pinch roller 122 and the second pinch roller 123 to be close to or apart from each other. Of course, in the third embodiment, the second clamping roller 123 may be rotatably disposed on the moving plate 125 around its own axis, and the clamping driving member 126 drives the second clamping roller 123 to move, so as to achieve that the first clamping roller 122 and the second clamping roller 123 approach or separate from each other.

Alternatively, the clamping driver 126 is a pneumatic cylinder. Of course, in other embodiments, the clamping driver 126 may be other driving structures, and is not limited herein.

It will be appreciated that when the feed drive 124 is in driving connection with the second nip roller 123, in the first embodiment the feed drive 124 is disposed on the mounting plate 121 and in the second and third embodiments the feed drive 124 is disposed on the moving plate 125. For ease of understanding, the following description is made with respect to the first embodiment.

In some embodiments, the surface of the second nip roller 123 is provided with a layer of glue. The glue coating layer can be in contact with the material belt 20 so as to increase the friction force between the second clamping roller 123 and the material belt 20 and avoid slipping between the second clamping roller 123 and the material belt 20 in the process of rotating to transfer the material belt 20.

Alternatively, the material of the glue layer is polyurethane, or other material that increases friction without damaging the tape 20.

Furthermore, it is understood that the surface of the first nip roller 122 may also be provided with a glue coating.

In some embodiments, one of the first nip roller 122 and the second nip roller 123 has a length that is not less than the width of the web 20, and the other has a length that is less than the width of the web 20. In this way, after clamping the material strip 20, the other of the first clamp roller 122 and the second clamp roller 123 does not press against the wavy edge of the material strip 20, avoiding creasing the material strip 20.

In particular, in the embodiment shown in fig. 2, the second nip roller 123 has a shorter length than the first nip roller 122, and the first nip roller 122 is located on the lower side of the web 20, and the second nip roller 123 is located on the upper side of the web 20.

In some embodiments, the clamping assembly 120 further includes a connecting shaft 127. The connecting shaft 127 and the first nip roller 122 are disposed opposite to each other on the mounting plate 121, and the connecting shaft 127 is rotatable about its own axis. The second pinch roller 123 is mounted to the connection shaft 127, and the second pinch roller 123 can rotate unidirectionally about the connection shaft 127. The feeding driving member 124 is in driving connection with the connecting shaft 127, and is capable of driving the connecting shaft 127 to rotate and driving the second clamping roller 123 to rotate so as to convey the feeding belt 20 along the conveying direction.

Further, the clamping assembly 120 also includes a one-way bearing. The second pinch roller 123 is mounted to the connecting shaft 127 through a one-way bearing. In this way, the second clamping roller 123 can rotate unidirectionally around the connecting shaft 127, so that the feeding driving member 124 can convey the material belt 20 downstream in the process of driving the second clamping roller 123 to rotate, and the material belt 20 is prevented from being conveyed upstream. Meanwhile, when the connecting shaft 127 does not rotate, the second clamping roller 123 can rotate, so that when the conveying speed of the clamped material belt 20 is higher than that of the clamping assembly 120, the clamping assembly 120 can be prevented from obstructing the movement of the material belt 20, and damage to the material belt 20 can be avoided.

In other embodiments, the first pinch roller 122 may be mounted to the connecting shaft 127 by a one-way bearing.

It should be noted that, the gripper assembly 120 conveys the material strip 20 to the downstream deviation correcting assembly 200 (refer to fig. 7), and the deviation correcting assembly 200 continues to convey the material strip 20 after obtaining the material strip 20, where the gripper assembly 120 does not move along the conveying direction of the material strip 20, so that the conveying speed of the material strip 20 gripped by the gripper assembly 120 is greater than the moving speed of the gripper assembly 120.

Of course, in other embodiments, it is also possible that the second pinch roller 123 in the pinch assembly 120 continues to rotate after the downstream mechanism captures the material web 20, and then the first pinch roller 122 is driven away from the second pinch roller 123 by the pinch drive 126.

In order to facilitate understanding of the technical solution of the present application, the working process of the feeding device 100 in the above embodiment is described herein with reference to fig. 3 to 8:

first, as shown in fig. 3 and 4, the driving member 110 drives the transfer plate 140 to move toward the downstream rectifying assembly 200 in the conveying direction (left direction in fig. 3 to 8) of the material web 20, so that the gripping assembly 120 and the cutting assembly 130 move toward the rectifying assembly 200 in synchronization. As shown in fig. 5, after the speed of the transfer plate 140 is the same as the conveying speed of the material belt 20, the gripper driving member 126 in the gripper assembly 120 operates to drive the first gripper roller 122 to approach the second gripper roller 123 so as to grip the material belt 20. Then, as shown in fig. 6, the cutting unit 130 operates to cut the material tape 20.

Next, as shown in fig. 7, the driving member 110 stops, and then the feeding driving member 124 drives the second clamping roller 123 to rotate, so that the material belt 20 is driven to continue to be conveyed towards the deviation rectifying assembly 200 in the process of rotating the second clamping roller 123 until the beginning end of the material belt 20 enters the deviation rectifying assembly 200. The feed drive 124 is then deactivated and the nip drive 126 drives the first nip roller 122 apart from the second nip roller 123. Next, as shown in fig. 8, the driving member 110 drives the transfer plate 140 back to the initial position, and at the same time, the deviation correcting assembly 200 continues to transfer the belt 20 downstream.

In this embodiment, the downstream of the cutting assembly 130 is the deviation rectifying assembly 200. In other embodiments, other mechanisms may be downstream of the severing assembly 130, without limitation.

In addition, the cutting assembly 130 is of a conventional structure, and the cutter in the cutting assembly 130 is reset after cutting the web 20 to avoid affecting the transfer of the web 20. The cutting assembly 130 is not described in detail herein.

Referring to fig. 9, the present application further provides a winding apparatus 10, where the winding apparatus 10 includes the feeding device 100 in the foregoing embodiment, so as to provide the pole piece through the feeding device 100.

With the winding apparatus 10, only one driving member 110 is required for driving the clamping assembly 120 and the cutting assembly 130 in the feeding device 100, so that the structure is more compact and the apparatus cost is low. Meanwhile, since one driving member 110 is provided, it is ensured that the speed at which the clamping assembly 120 and the cutting assembly 130 move in the conveying direction of the material web 20 is the same. Compared with the prior two moving parts, the control mode of one driving piece 110 is simpler, thereby being more convenient to control and having higher efficiency.

In some embodiments, the winding apparatus 10 further comprises a first unwind device 310, a second unwind device 320, a first unwind mechanism 410, and a second unwind mechanism 420. The first unreeling device 310 and the second unreeling device 320 are used for outputting the first membrane 30 and the second membrane 40, respectively. The first unreeling mechanism 410 and the second unreeling mechanism 420 are used for outputting the cathode pole piece 50 and the anode pole piece 60, respectively.

Further, the winding apparatus 10 includes a film combining device 500, a winding device 600, and two feeding devices 100. The film combining device 500 is disposed downstream of the first unreeling device 310, the second unreeling device 320, the first unreeling mechanism 410 and the second unreeling mechanism 420, and is used for combining the first separator 30, the cathode pole piece 50, the second separator 40 and the anode pole piece 60 to form the combined material belt 70.

One of the feeding devices 100 is disposed between the first unreeling mechanism 410 and the laminating device 500, and is used for cutting off the cathode sheet 50 passing through and conveying the beginning end of the cathode sheet 50 downstream. The other feeding device 100 is disposed between the second unreeling mechanism 420 and the film doubling device 500, and is used for cutting off the anode pole piece 60 passing through and conveying the beginning end of the anode pole piece 60 downstream.

The winding device 600 is disposed downstream of the laminating device 500, and is used for winding the composite material tape 70 to form a battery cell.

In some embodiments, the winding apparatus 600 includes a turret 610 and at least two winding pins 620 mounted on the turret 610. Each winding needle 620 can be extended or retracted relative to the turret 610. Turret 610 is rotatably arranged to carry each winding needle 620 sequentially through a first station and a second station.

The first station is located downstream of the film doubling device 500, so that the combined material strip 70 formed after the film doubling device 500 is gathered reaches the winding needle 620 of the first station and is wound on the winding needle 620 to form a battery cell.

Further, the winding apparatus 10 further includes a guide roller 700 and a cutter device 800. The guide roller 700 is disposed between the first station and the second station for the combined tape 70 between the first station and the second station to be wound. Cutter device 800 is disposed between the first station and the second station for cutting the web 70.

When the winding needle 620 at the first station rotates to the second station along with the turret 610, the other winding needle 620 rotates to the first station, and the combined material belt 70 between the first station and the second station winds around the guide roller 700, so that the slit of the winding needle 620 at the first station is aligned with the combined material belt 70, and the combined material belt 70 can smoothly enter the slit of the winding needle 620 when the winding needle 620 at the first station extends, thereby facilitating the subsequent winding.

In some embodiments, the winding apparatus 10 further includes a deviation rectifying assembly 200. The deviation rectifying assembly 200 is disposed on the feeding device 100 and the film combining device 500, and the deviation rectifying assembly 200 can rectify the material belt 20.

It is determined that the material tape 20 in the present embodiment may be either one of the cathode sheet 50 and the anode sheet 60.

Specifically, the deviation correcting assembly 200 includes two deviation correcting rollers. The material strip 20 transferred from the gripper assembly 120 to the deviation rectifying assembly 200 can be gripped between two deviation rectifying rollers and can be transferred downstream by the driving of the deviation rectifying rollers.

In some embodiments, the deflection roller has a non-return function to limit the conveyance of the web 20 gripped thereby toward the feeding device 100.

It should be noted that, assuming that the material tape 20 is transferred from the feeding device 100 to the laminating device 500, the deviation correcting roller rotates in the forward direction. The deviation correcting roller has a non-return function, that is, a rotation stopping structure for limiting the deviation correcting roller to rotate in the opposite direction is arranged in the deviation correcting assembly 200, for example, the deviation correcting roller is supported by a one-way bearing, so that the material belt 20 clamped by the deviation correcting roller is limited to be conveyed towards the feeding device 100 by limiting the reverse rotation of the deviation correcting roller.

In addition, in other embodiments, the deviation of the material belt 20 may be directly corrected by the clamping assembly 120 in the feeding device 100, without the deviation correcting assembly 200 being disposed downstream of the feeding device 100.

Specifically, a correction driving member is provided in the feeding device 100. The deviation rectifying driving member is disposed on the transfer plate 140, and is in transmission connection with the clamping assembly 120 and the cutting assembly 130, so as to drive the clamping assembly 120 and the cutting assembly 130 to move along the width direction of the material belt 20. Therefore, after the clamping assembly 120 clamps the material belt 20, the deviation rectifying driving member drives the clamping assembly 120 and the cutting assembly 130 to synchronously move, so as to rectify the material belt 20.
