Embodiment 1

[0045] Embodiment 1 of the present invention, a tension control method and a pole piece laser cutting and rolling machine. The material roll 12 is pulled out, and the pole piece 9 is transported to the laser cutter 41. The laser cutter 41 die-cuts the pole piece 9. After the pole piece 9 is die-cut, it is transported to the pressing roller 62, and the rolling motor 63 The pressure roller 62 is driven to rotate, and the pole piece 9 passes between the two pressure rollers 62. At the same time, the pressure roller 62 rolls the pole piece 9, and the piston rod of the rotating cylinder 54 expands and contracts, and the tension of the pole piece 9 is adjusted. The winding motor works to drive the winding roller 72 to rotate, so that the rolled pole piece 9 is rolled up; the position of the pole piece 9 in the width direction of the pole piece 9 is fed back in real time through the sensor, and the correcting frame 22 is precisely driven to move in a closed loop, thereby adjusting In...

Embodiment 2

[0046] Embodiment 2: The difference from Embodiment 1 is that the position order of each device of the all-in-one machine is different. Specifically, refer to Figure 7 , including an unwinding device 1, a deviation correcting device 2, a swing roller 53 device 5, a rolling device 6, a traction device 3, a laser die cutting device 4, a detection device 8, a winding device 7 and a control system, and a deviation correcting device 2 There are two devices, one of which is set at the feeding place of the all-in-one machine, and the other one is set at the discharge place of the all-in-one machine, and two pendulum rollers 53 devices 5 are provided. Located on opposite sides of the rolling device 6 .

Abstract

The invention discloses a tension control method and a laser cutting and rolling integrated machine for pole pieces. The laser cutting and rolling integrated machine comprises an unwinding device, two deviation rectifying devices, a traction device, a laser die cutting device, a swing roller device, a winding device, a winding device and a control system, wherein one deviation rectifying device is arranged at the feeding position of the integrated machine, and the other deviation rectifying device is arranged at the discharging position of the integrated machine; the traction device is used for clamping pole pieces; the laser die cutting device is used for die cutting of the pole pieces; the swing roller device is used for adjusting the tension of the pole pieces; and the rolling device is used for rolling the pole pieces. The laser cutting and rolling integrated machine has the effect that the tension is stabilized, so as to improve the production stability.

Description

technical field [0001] The invention relates to the technical field of lithium-ion battery pole piece production, in particular to a tension control method and a pole piece laser cutting and rolling machine. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels and new vehicle power devices), and the comprehensive vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure.
