Description

Technical Field

[0002] In the manufacturing process of batteries, pole pieces are generally required, but pole pieces are very wide at the beginning. In order to facilitate the use of pole pieces, pole pieces need to be cut so that they can be made into part of the battery. Before or after cutting, the pole pieces need to be cut and formed into pole ears. Laser die-cutting is widely used in the forming of pole ears of battery pole pieces due to its characteristics of small cutting burrs, low maintenance cost and high flexibility. The main solutions for pole ear forming are: 1. First cut the pole piece, and then perform laser die-cutting to form the pole piece pole ear; 2. First perform laser die-cutting on the pole piece to form the pole piece pole ear, and then cut it. Regardless of which method is used, the slitting equipment and laser die-cutting equipment that work independently of each other are used for auxiliary processing combined with manual operation.

Its working principle is as follows: the pole piece is unwound through the turret unwinding assembly 10; after the pole piece passes through the roller and the tape connection platform assembly 20, it passes through the tension detection assembly 30 and the tension swing roller assembly 40 to perform real-time tension detection and tension adjustment on the pole piece on the tape to ensure smooth tape running of the pole piece, and then the pole piece foil area is embossed through the reinforcing rib assembly 50 to enhance the anti-folding ability of the pole ear; then the pole piece is corrected by the pre-die-cutting advancing correction assembly 60, and the pole ear is cut by the laser length measurement assembly 70 and the laser assembly 80; after the pole ear is formed, it passes through the pole ear air knife dust removal assembly 90 to remove dust from the pole ears on both sides; the main drive assembly 100 pulls the pole piece and tension isolates it; the pole ear CCD size detection assembly 110 detects and feedbacks the pole ear size and pole ear defects, and in the case of NG, it is fed back to the bad labeling assembly 170 for labeling processing; the A-side CCD defect detection assembly 120 is used to detect the width and surface defects of the pole piece after die-cutting, and the pole ear before die-cutting The traveling correction component 60 forms a closed-loop control to ensure cutting accuracy; the traveling correction component 130 corrects the centering of the electrode piece before slitting, and the slitting mechanism 140 cuts the electrode piece in the center, and the electrode piece is divided into two parts, namely, the upper and lower belts; the upper and lower belts are sequentially provided with the B-side CCD defect detection component 150, the brush dust removal component 160, the bad labeling component 170, the iron removal component 180, the winding tension detection component 190 and the turret winding component 200 along the belt direction, and the B-side CCD defect detection component 150, the brush dust removal component 160, the bad labeling component 170, the iron removal component 180, the winding tension detection component 190 and the turret winding component 200 are arranged in sequence. The D defect detection component 150 performs width detection and surface defect detection on the pole piece after slitting, and forms a closed-loop control with the advance correction component 130 before slitting to ensure the slitting width accuracy. The brush dust removal component 160 and the iron removal component 180 remove dust and iron from the surface of the pole piece. The winding tension detection component 190 cooperates with the magnetic powder clutch on the winding shaft to control the tension stability of the pole piece during winding, avoid belt breakage and ensure neat winding, and finally winding is carried out through the turret winding component 200.

[0033] Specifically, the turret unwinding assembly 10 includes a first unwinding shaft, a first rotating axis and a second unwinding shaft. The first unwinding shaft and the second unwinding shaft are relatively arranged to rotate through the first rotating axis. A first automatic belt connecting assembly 210 is rotatably arranged on one side of the turret unwinding assembly 10. The first automatic belt connecting assembly 210 includes a first rocker mechanism, a first rotating cylinder arranged at the end of the first rocker mechanism, and a first cutter arranged on the first rotating cylinder. When the first unwinding shaft of the turret unwinding assembly 10 reaches the lower limit and needs to be changed, the equipment starts to slow down, and the second unwinding shaft equipped with double-sided tape rotates 180° counterclockwise around the first rotation axis and exchanges positions with the first unwinding shaft. After the tail material pole piece of the first unwinding shaft is pressed tightly against the second unwinding shaft by the tape pressing roller of the first swing arm mechanism of the first automatic tape splicing assembly, the first cutter cuts off the tail material pole piece through the rotation of the first rotating cylinder, and the second unwinding shaft starts to rotate counterclockwise. When the tape on the second unwinding shaft sticks to the tail material of the first unwinding shaft, the pole piece on the second unwinding shaft is connected to the pole piece of the first unwinding shaft to realize automatic reel change. At the same time, the first swing arm mechanism pops open and resets, and the equipment starts to speed up unwinding.

The second automatic belt connecting assembly 220 includes a second rocker arm mechanism, a second rotating cylinder arranged at the end of the second rocker arm mechanism and a second cutter arranged on the second rotating cylinder. When the first winding shaft of the turret winding assembly 200 reaches the upper limit and needs to be changed, the equipment begins to lower, and the second winding shaft equipped with double-sided tape rotates 180° counterclockwise around the second rotation axis and exchanges position with the first winding shaft. The auxiliary support structure holds the shaft end to ensure the bearing weight of the winding shaft. After the pole piece on the first winding shaft is pressed tightly against the second winding shaft by the tape pressing roller of the second swing arm mechanism of the second automatic tape splicing assembly, the second cutter cuts off the tail pole piece through the rotation of the second rotating cylinder, and the second winding shaft begins to rotate clockwise. When the tape on the second winding shaft sticks to the pole piece of the first winding shaft, the pole piece on the second winding shaft is connected to the pole piece on the first winding shaft to realize automatic winding. At the same time, the second swing arm mechanism pops open and resets, and the equipment starts to speed up the unwinding and resume normal production. The flipped first winding shaft can also unload the pole roll through the pushing mechanism.

[0036] This wide-width automated laser die-cutting machine can automate the entire process without manual intervention, saving time and effort, greatly reducing labor costs, and improving production efficiency, thereby reducing the risk of manual operation errors and labor costs. In addition, both the unwinding and rewinding processes can be changed and spliced ​​without stopping the machine, saving loading and unloading time and improving the overall OEE of the equipment.
