PI film explanation:

PI film is also called polyimide film. Its main component is polyimide, which is one of the films with high temperature resistance and good stability. PI film is a film widely used in the field of electronic products. The color is usually brown and black. The types of hot melt films bonded by PI film are PA and PES hot melt films.

Advantages of laser cutting PI film, cutting of various film materials in PCB/FPC and other industries:

(1) Imported laser, non-contact cutting, high cutting quality, small heat-affected zone, which can be ignored.

(2) Free switching between dual-axis and single-axis, convenient for cutting of various materials;

(3) Synchronous processing at both ends to improve cutting efficiency;

(4) Fully automatic visual system, automatic positioning, more accurate cutting;

(5) Fully automatic feeding and receiving device, saving manpower, convenient and fast.

The fully automatic laser film cutting machine is a high-tech product that integrates visual positioning, laser cutting, and automatic feeding. It is also an intelligent robot.

Diaphragm: It is an important component of a micro-microphone (microphone). It is widely used in various microphones, mobile phones, walkmans, micro speakers, etc. China's diaphragm production accounts for 90% of the world. 4 billion pieces are needed every year.

Diaphragm is also an important part of electronic cigarettes. China is also a major producer of electronic cigarettes, accounting for 95% of the world's production, most of which are exported. The output in 2015 was 860 million pieces, and it should be more than 1 billion pieces in 2016. Electronic cigarettes need diaphragms, and 1 billion pieces are needed every year.

The diaphragm is a tiny component with a copper ring of about 3 mm in diameter attached to a film with a thickness of 0.02 mm. There are up to more than 1,000 diaphragms on a film, which need to be cut one by one. The cutting requirements are extremely high. The diaphragm after cutting cannot have burrs, large and small edges, and the allowable error is 0.02 mm. In the past, it relied on manual cutting. A female worker works 12 hours a day, cutting about 20,000 pieces, and the work intensity is high. He often cannot recruit workers, and even goes to the prison to find female prisoners to cut. In addition, the cutting blade wears out a lot, and 7-8 knives need to be replaced every day.

The fully automatic laser film cutting machine realizes fully automatic cutting, with a cutting speed of about 30,000 pieces per hour. The workload of one machine is equivalent to the workload of 13-14 workers. Because it is laser cutting, there is no problem of tool wear and replacement. Working process of laser cutting machine:

Put the entire diaphragm on the workbench, trigger the start signal, and the workbench moves under the industrial camera lens;

The camera collects images and provides diaphragm position data based on the image computer;

The workbench receives position movement information, and the laser cutting machine receives diaphragm position data. According to the position data, the diaphragms are cut one by one, and during this period, the movement is coordinated. After taking the first equal division, the workbench is moved to the laser cutting station, and after taking the second equal division, the laser starts to cut the first equal division. Wait a minute, repeat. Within a few seconds after taking the last equal division, the laser cuts the last equal division.

Laser cutting machine technology is advanced: visual positioning is high-precision. Visual positioning is not high-tech, but visual positioning accurate to 0.02 mm is high-tech, including visual technology, high-precision mechanical structure, high-precision laser cutting technology, computer algorithms and motion control technology.
