[0031] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] Example:

[0033] See also Figure 1 and Figure 2 , Figure 1 A schematic structural diagram of a pole piece driving device 10 provided in an embodiment of the present invention applied to a pole piece cutting system 100 at a first viewing angle. Figure 2 The schematic diagram of the structure of the pole piece driving device 10 provided in the embodiment of the present invention applied to the pole piece cutting system 100 from a second viewing angle. Figure 2 The direction indicated by the arrow A is the first direction A.

[0034] The embodiment of the present invention provides a pole piece driving device 10, which is used to transfer the pole piece 900 to the cutting device 20. The pole piece driving device 10 has the characteristics that the driving point can be close to the cutting position, and it is not easy to cause material blocking and bending of the pole piece 900, and the production accuracy can be improved. The pole piece driving device 10 can be applied to the pole piece cutting system 100 or the pole piece 900 production assembly line, etc.

[0035] Among them, taking the pole piece driving device 10 applied to the pole piece cutting system 100 as an example, the pole piece cutting system 100 includes a pole piece driving device 10 to transmit the pole piece 900 through the pole piece driving device 10. Of course, the pole piece cutting system 100 can also include a cutting device 20, which is arranged close to the pole piece driving device 10 and is used to receive the pole piece 900 transmitted by the pole piece driving device 10.

[0036] Since the pole piece cutting system 100 adopts the pole piece driving device 10 provided in the embodiment of the present invention, the pole piece cutting system 100 also has the characteristics that the driving point can be close to the cutting position, and it is not easy to cause blockage and bending of the pole piece 900, which can improve the production accuracy.

[0037] The following will specifically introduce the structural composition, working principle and beneficial effects of the pole piece driving device 10 provided in an embodiment of the present invention.

[0038] See also Figure 3 , Figure 3 A schematic structural diagram of a pole piece driving device 10 provided in an embodiment of the present invention.

[0039] The pole piece driving device 10 includes two groups of symmetrically arranged belt conveying mechanisms 12 for jointly conveying the pole piece 900 to the cutting device 20 .

[0040] The belt conveyor mechanism 12 includes a driving shaft 121, a conveyor belt 122 and two rollers 123, wherein the driving shaft 121 is used to drive the conveyor belt 122 to rotate, the driving shaft 121 and the two rollers 123 are arranged in parallel with each other, or in other words, the driving shaft 121 is parallel to the two rollers 123, the conveyor belt 122 is wound around the driving shaft 121 and the two rollers 123, and one side of the conveyor belt 122 unfolded between the two rollers 123 is a conveying side 1221, which is used to convey the pole piece 900. The outer side surfaces of the two conveying sides 1221 of the two groups of belt conveyor mechanisms 12 are parallel and oppositely arranged on both sides of the conveying path 910, and the two conveying sides 1221 can clamp the pole piece 900 together to convey the pole piece 900 to the cutting device 20 along the conveying path 910.

[0041] In this way, the two groups of belt conveyor mechanisms 12 are symmetrically arranged, and their conveying edges 1221 are relatively arranged and used to jointly convey the pole piece 900. The pole piece 900 is conveyed to the cutting device 20 through the conveying edges 1221 of the two groups of belt conveyor mechanisms 12. Since the diameter of the roller 123 of the belt conveyor mechanism 12 is relatively small, the end of the belt conveyor mechanism 12 can be closer to the cutting mechanism. In addition, since the pole piece 900 is conveyed through two conveying edges 1221 and the end of the conveying edge 1221 can be closer to the cutting device 20, the pole piece 900 between the belt conveyor mechanism 12 and the cutting device 20 is not prone to blockage and bending, thereby improving the production accuracy.

[0042] It should be noted that the existing pole piece 900 uses a driving roller to convey the pole piece 900 before cutting. Due to the large size of the driving roller, the driving point of the driving roller is far away from the cutting position of the cutting device 20, which makes it easy for the pole piece 900 to be blocked and bent between the driving roller and the cutting device 20. In addition, in this embodiment, the driving shaft 121 and the two rollers 123 open the conveyor belt 122 so that the cross section of the conveyor belt 122 is triangular, or in other words, the projection of the conveyor belt 122 on the plane perpendicular to the first direction A is triangular, wherein the first direction A is the axial direction of the driving shaft 121.

[0043] See also Figure 3 and Figure 4 , Figure 4 for Figure 2 Schematic diagram of the enlarged structure at IV in FIG.

[0044] The driving shaft 121 may be provided with a first driving tooth (not shown) and a second driving tooth 1212 coaxially arranged with the driving shaft 121, and the two first driving teeth of the two groups of belt conveyor mechanisms 12 are meshed with each other. In this way, the two conveyor belts 122 can be rotated synchronously by the two first driving teeth, thereby improving the stability of the pole piece driving device 10 in transporting the pole piece 900.

[0045] The inner side of the conveyor belt 122 may also be provided with transmission teeth, which mesh with the corresponding second driving teeth 1212 to drive the conveyor belt 122 to rotate stably, reduce the probability of the conveyor belt 122 slipping, and further improve the stability of the pole piece driving device 10 in conveying the pole piece 900.

[0046] It should be noted that the pole piece driving device 10 may further include a driving member (not shown), which is engaged with any one of the first driving teeth to drive the two driving shafts 121 to rotate.

[0047] Furthermore, the two sides of the conveyor belt 122 unfolded between the driving shaft 121 and the roller 123 can be tensioning edges 1222, and the belt conveyor mechanism 12 can also include two tensioning wheels 125, and the two tensioning wheels 125 are respectively abutted against the two tensioning edges 1222. In this way, the left and right sides of the conveyor belt 122 are tensioned by the tensioning wheels 125 at the same time, so that the head end and the end of the conveying edge 1221 are tensioned, further improving the stability of the conveying pole piece 900 of the belt conveyor mechanism 12.

[0048] Furthermore, the belt conveyor mechanism 12 may also include a supporting portion 126, which is arranged in a strip shape, is located in the conveyor belt 122, and is extended along the extension direction of the conveying edge 1221. The supporting portion 126 is used to support the conveying edge 1221 toward the outer side of the conveying edge 1221. In other words, the supporting portion 126 is extended in the conveyor belt 122 along the conveying direction of the pole piece 900, and is supported against the inner side of the conveying edge 1221, so that when the conveying edge 1221 is conveyed, each position on it is evenly supported against the pole piece 900, so as to stably convey the pole piece 900 and reduce the probability of bending of the pole piece 900 between the two conveying edges 1221.

[0049] Please continue reading Figure 4 The pole piece driving device 10 may further include a plurality of conveying brackets 13, which are respectively arranged on both sides of the conveyor belt 122 in the first direction A, and are all used to hold up the pole piece 900. In this way, when the pole piece 900 is conveyed, the conveyor belt 122 drives the pole piece 900, and the conveying brackets 13 hold up the pole piece 900, so as to jointly maintain the smooth conveying of the pole piece 900, and further improve the stability of the conveying of the pole piece 900.

[0050] See also Figure 4 and Figure 5 , Figure 5 for Figure 2 Enlarged schematic diagram of the structure at V in the middle.

[0051] The pole piece drive device 10 may also include a feeding mechanism 15, which includes a first feeding member 151. The first feeding member 151 may include two feeding blocks 1511. The two feeding blocks 1511 are arranged near the end of the belt conveyor mechanism 12. There is a gap between the two feeding blocks 1511, which is the first feeding gap 1512 for the pole piece 900 to pass through, and the transmission path 910 is arranged through the first feeding gap 1512, that is, the pole piece 900 is transmitted through the first feeding gap 1512. In this way, in the process of conveying the pole piece 900 by the conveyor belt 122, when the pole piece 900 is about to leave the transmission edge 1221, or when the pole piece 900 has just left the transmission edge 1221, the pole piece 900 enters the first feeding gap 1512, so as to limit the position of the pole piece 900 by the two feeding blocks 1511, thereby further reducing the probability of bending or blocking of the pole piece 900.

[0052] It should be noted that the feed block 1511 may have a feed slope 1513 that is set at an angle to the conveying path 910, and the feed slopes 1513 of the two feed blocks 1511 together form a V-shaped opening to receive the pole piece 900 conveyed by the belt conveyor mechanism 12 to the first feed interval 1512. In other words, the two feed slopes 1513 are set in a direction opposite to the conveying direction of the pole piece 900 to guide the pole piece 900 into the first feed interval 1512, so that the feed block 1511 limits the position of the pole piece 900.

[0053] Furthermore, the number of the first feeding members 151 can be multiple, and the multiple first feeding members 151 are arranged in intervals along the first direction A, and the roller 123 at the end of the belt conveyor mechanism 12 is located in the interval between two adjacent first feeding members 151. In this way, when the pole piece 900 just leaves the conveying edge 1221, it enters between the two feeding blocks 1511, so as to further reduce the bending probability of the pole piece 900.

[0054] Furthermore, the feeding mechanism 15 may also include a second feeding member 152, which includes two feeding strips 1521, and the two feeding strips 1521 are extended along the conveying path 910, and there is a second feeding gap 1522 between the two feeding strips 1521, and the second feeding gap 1522 is connected to the first feeding gap 1512, and the conveying path 910 passes through the second feeding gap 1522, or in other words, the pole piece 900 is conveyed in sequence between the two conveying edges 1221, the first feeding gap 1512 and the second feeding gap 1522, so as to provide the cutting device 20 with a side surface of the feeding strip 1521 in the first direction A to receive the pole piece 900.

[0055] In this way, the cutting device 20 receives the pole piece 900 on the second feeding member 152 to avoid bending of the pole piece 900 , thereby further improving the manufacturing accuracy.

[0056] It should be noted that, in this embodiment, the number of second feeding members 152 can be multiple, and the multiple second feeding members 152 are arranged at intervals along the first direction A, and the interval between two adjacent second feeding members 152 is used for the cutting device 20 to enter and receive the pole piece 900, thereby further improving the accuracy of the cutting device 20 in receiving and cutting the pole piece 900.

[0057] The working principle of the pole piece driving device 10 provided in the embodiment of the present invention is:

[0058] The driving shaft 121 is used to drive the conveyor belt 122 to rotate. The driving shaft 121 and the two rollers 123 are arranged parallel to each other, or in other words, the driving shaft 121 is parallel to the two rollers 123 respectively. The conveyor belt 122 is wound around the driving shaft 121 and the two rollers 123, and one side of the conveyor belt 122 unfolded between the two rollers 123 is a conveying side 1221 for conveying the pole piece 900. The outer side surfaces of the two conveying sides 1221 of the two groups of belt conveyor mechanisms 12 are parallel and oppositely arranged on both sides of the conveying path 910, and the two conveying sides 1221 can clamp the pole piece 900 together to convey the pole piece 900 to the cutting device 20 along the conveying path 910. In this way, the two groups of belt conveyor mechanisms 12 are symmetrically arranged, and their conveying edges 1221 are relatively arranged and used to jointly convey the pole piece 900. The pole piece 900 is conveyed to the cutting device 20 through the conveying edges 1221 of the two groups of belt conveyor mechanisms 12. Since the diameter of the roller 123 of the belt conveyor mechanism 12 is relatively small, the end of the belt conveyor mechanism 12 can be closer to the cutting mechanism. In addition, since the pole piece 900 is conveyed through two conveying edges 1221 and the end of the conveying edge 1221 can be closer to the cutting device 20, the pole piece 900 between the belt conveyor mechanism 12 and the cutting device 20 is not prone to blockage and bending, thereby improving the production accuracy.

[0059] In summary:

[0060] The embodiment of the present invention provides a pole piece driving device 10, which has the characteristics that the driving point can be close to the cutting position, and is not prone to material blockage and bending of the pole piece 900, thereby improving the production accuracy.
