[0003] The existing winding and splicing device of the slitting equipment generally includes two side plates arranged opposite to each other in front and back, a first winding shaft, a second winding shaft, a first winding drive assembly for driving the first winding shaft to rotate, a second winding drive assembly for driving the second winding shaft to rotate, a first fixed roller, a second fixed roller, a third fixed roller, a fourth fixed roller and a belt pressing assembly. The first winding shaft and the second winding shaft are respectively rotatably arranged on the inner side of one of the side plates and the two are arranged opposite to each other in the upper and lower directions. The first fixed roller, the second fixed roller, the third fixed roller and the fourth fixed roller are respectively arranged between the two side plates. The third fixed roller is located on the left side between the first winding shaft and the second winding shaft, the second fixed roller is located on the left side of the third fixed roller, the first fixed roller is located above the second fixed roller, and the fourth fixed roller is located below the third fixed roller.

[0004] During actual winding, for example, the first reel and the second reel are first installed on the first winding shaft and the second winding shaft respectively, and the leading end of the electrode piece cut by the slitting mechanism of the slitting equipment passes through the right side of the first fixed roller, the left side of the second fixed roller, and the bottom of the third fixed roller in sequence, and then adheres to the adhesive on the first reel, and the first winding shaft is driven to rotate by the first winding drive assembly, thereby driving the first reel to rotate, so that the electrode piece can be wound on the first reel. When the roll diameter of the electrode on the first reel reaches the preset value, the winding and splicing device is manually controlled to stop, and the pressing device is started to press the electrode onto the first fixed roller to prevent the cutter of the pressing device from deviating when cutting the electrode. The electrode is then cut by the cutter of the pressing device, and the cut end of the electrode is manually passed through the right side of the third fixed roller and the left side of the fourth fixed roller and bonded to the adhesive on the second reel of the second winding shaft, so that the splicing is achieved. Then the winding and splicing device is started, and the second winding shaft is driven to rotate by the second winding drive assembly, thereby driving the second reel to rotate, so that the electrode can be wound on the second reel. This device needs to be spliced ​​manually, and the machine needs to be stopped during the splicing process, which increases production time, reduces production efficiency, and increases production costs.

[0064] The working principle of the utility model is as follows: firstly, the first reel 20 and the second reel 30 are respectively installed on the first winding shaft and the second winding shaft, and the leading end of the slit pole piece passes through the bottom of the roller body of the fourth roller 94, the bottom of the roller body of the second roller 92, and the bottom of the pressure roller body 732 of the upper cutter swing arm mechanism 70 in sequence, and then adheres to the adhesive on the first reel 20, and the first winding shaft is driven to rotate by the first winding drive assembly, thereby driving the first reel 20 to rotate, so that the pole piece can be wound on the first reel 20, as shown in FIG. Fig.12 When the roll diameter of the pole piece roll on the first roll 20 reaches the preset value, the two mounting plates 41 are first driven downward to the tape connection position by the lifting drive assembly, as shown in FIG. Fig.13As shown, at this time, the pole piece can be supported by the roller body of the third roller 93 and the roller body of the first roller 91, and then the second winding shaft is driven to rotate by the second winding drive assembly, thereby driving the second reel 30 to rotate, so that the maximum linear velocity of the outer diameter of the second reel 30 is the same as the tape running speed of the pole piece, and then the two support plates 72 of the upper cutter swing arm mechanism 70 are driven to move right by the first horizontal driving mechanism 50, thereby driving the rotation driving assembly, the pressure roller 73, and the cutter swing arm assembly of the upper cutter swing arm mechanism 70 to move right, so that the pole piece can be pressed onto the second reel 30 by the pressure roller body 732 of the upper cutter swing arm mechanism 70, as shown in FIG. Fig.14 As shown, the pole piece is bonded to the adhesive on the second reel 30, and then the two swing arms 741 are driven to rotate in a clockwise direction by the rotating drive assembly of the upper cutter swing arm mechanism 70, thereby driving the cutter 744 of the upper cutter swing arm mechanism 70 to rotate in a clockwise direction to cut the pole piece, and at the same time, the first winding drive assembly stops driving the first winding shaft to rotate, thus completing the tape splicing. After completion, the two swing arms 741 are driven to rotate counterclockwise to the initial position by the rotation drive assembly of the upper cutter swing arm mechanism 70, thereby driving the cutter 744 of the upper cutter swing arm mechanism 70 to rotate counterclockwise to the initial position, and then the two support plates 72 of the upper cutter swing arm mechanism 70 are driven to move left to the initial position by the first horizontal drive mechanism 50, thereby driving the rotation drive assembly, the pressure roller 73 and the cutter swing arm assembly of the upper cutter swing arm mechanism 70 to move left to the initial position, and then the two mounting plates 41 are driven to move upward to the initial position by the lifting drive assembly, thereby driving the first horizontal drive mechanism 50, the second horizontal drive mechanism 60, the upper cutter swing arm mechanism 70 and the lower cutter swing arm mechanism 80 to move upward to the initial position.

When the winding diameter of the pole piece material roll on the second reel 30 reaches the preset value, the two mounting plates 41 are first driven upward to the tape connection position by the lifting drive assembly. At this time, the pole piece can be supported by the roller body of the first roller 91.

Then the two support plates 72 of the lower cutter swing arm mechanism 80 are driven to move to the right by the second horizontal drive mechanism 60, thereby driving the lower cutter swing arm mechanism 80 to rotate. The rotating drive assembly, pressure roller 73 and cutter swing arm assembly of the arm mechanism 80 move to the right, so that the pole piece can be pressed onto the first reel 20 through the pressure roller body 732 of the lower cutter swing arm mechanism 80, so that the pole piece is bonded to the adhesive on the first reel 20, and then the two swing arms 741 are driven to rotate in the counterclockwise direction through the rotating drive assembly of the lower cutter swing arm mechanism 80, so that the cutter 744 of the lower cutter swing arm mechanism 80 can be driven to rotate in the counterclockwise direction to cut the pole piece, and at the same time, the second winding drive assembly stops driving the second winding shaft to rotate, thus completing the tape splicing. After completion, the two swing arms 741 are driven to rotate in the clockwise direction to the initial position through the rotation drive assembly of the lower cutter swing arm mechanism 80, thereby driving the cutter 744 of the lower cutter swing arm mechanism 80 to rotate in the clockwise direction to the initial position, and then the two support plates 72 of the lower cutter swing arm mechanism 80 are driven to move to the left to the initial position through the second horizontal drive mechanism 60, thereby driving the rotation drive assembly, the pressure roller 73 and the cutter swing arm assembly of the lower cutter swing arm mechanism 80 to move to the left to the initial position, and then the two mounting plates 41 are driven to move downward to the initial position through the lifting drive assembly, thereby driving the first horizontal drive mechanism 50, the second horizontal drive mechanism 60, the upper cutter swing arm mechanism 70 and the lower cutter swing arm mechanism 80 to move downward to the initial position. At this time, the pole piece passes from the bottom of the roller body of the fourth roller 94, the bottom of the roller body of the second roller 92, and the bottom of the pressure roller body 732 of the upper cutter swing arm mechanism 70 and is wound on the first reel 20. Then the second reel 30 and the pole piece material roll on the second reel 30 are taken off from the second winding shaft, and a new second reel 30 is installed on the second winding shaft again to wait for the next tape splicing.
