Functional Description of Film Production Process and Cutting Control System

In addition, the laser parameters used for different parts of the polar ear are individually set and adjusted, and all are equipped with laser power and frequency tracking to ensure consistency in the cutting effect of different parts.
At present, our control system supports mainstream fiber laser manufacturers such as IPG SPI、 Ruike, Jept, and others support cutting control for both pulsed fiber lasers and medium to high power continuous fiber lasers. The choice of laser cutting method depends on the customer's process.

Optical system and cutting effect description

There are two aspects to selecting the working distance of the lens: one is to choose based on the actual cutting effect, and the other is to take into account the layout of the mechanical structure. For example, a smaller working distance will compress the upper limit of the mechanical structure, such as affecting the placement of the dust removal system and belt mechanism.

Optical system and cutting effect description

The left image shows the AT9 effect, with neat and uniform cutting end faces without burrs exceeding the coating. The right image shows the negative graphite cutting end face without burrs exceeding the coating

Optical system and cutting effect description

AT9 effect display: The cutting end face is neat and uniform, without burrs beyond the coating, and the straight line area and R-angle heat affected zone are both less than 60um.

Optical system and cutting effect description

Display of Extreme Ear Area Effect: The left image shows the copper foil end face with a width of 10.49um after cutting, which meets the process requirement of less than 40um. The right image shows the heat affected zone with a width of 58.97um, which meets the process requirement of less than 100um.
