High-speed spectroscopic laser welding machines are gradually replacing traditional manufacturing and are widely used in precision welding, 3C electronics, automobiles, new energy, home appliance hardware and other fields.
As we know, a general laser welding machine has three kinds of spectroscopic methods: time spectrum, energy spectrum, high-speed spectrum.
Time spectrum is the laser energy output respectively to two or more welding heads according to the time sequence. Energy spectrum is the laser energy output divided into two or more welding heads. Expect the above two, high-speed spectrum is also a kind of spectroscopic method. Different from the traditional light gate, the high-speed spectrum can switch the light path quickly at an average frequency of 80Hz, meanwhile, the efficiency is greatly improved. The speed advantage is obvious while welding in a multi-station. This kind of method is not only the equipment cost could be greatly saved, but also the occupied equipment space reduced effectively, and the corresponding maintenance cost is also lower.
The fiber high-speed spectral laser welding machine can be divided into time spectral and power spectral:
Time spectral means that the light is emitted in different periods of time, and the time period is very short, which is invisible to people's eyes, so it gives us the feeling that the light is emitted at the same time, and it is guaranteed that the maximum power can be used every time the light is emitted. (For example, 1000W is divided into 2 optical fiber outputs, and the light is emitted at different times to ensure that there is 1000W power for each light output). In this way, operators can be divided into 2 to 4 stations for alternate welding to save refueling time.
Power spectral is usually used for high power, such as 400W, 500W, or 600W, the power is evenly distributed to each fiber line, and the light is welded at the same time (such as 600W is divided into 2 fiber output, then each line has 300W power available).
The advantages are as below:
It can realize light splitting in time and energy, can process multiple beams at the same time, and realize more precise welding.
The cooling medium is purified so that the life of the device is prolonged and the daily maintenance is more convenient.
There is no pollution in processing, small heat-affected zone, and small deformation.
The welding seam is fine, the depth is large, the taper is small, the precision is high, and the appearance is smooth, flat, and beautiful.
After welding, the product will not be deformed or yellowed, the welding seam will be smooth, and the size of the welding spot will be uniform.
It is controlled by a PC and assisted by special software. The operation is simple and easy to learn; any graphic characters can be welded.
No consumables, small size; flexible processing, low operating cost.
Optical fiber output, which can be freely matched with manipulators or assembly lines.
The high-speed spectroscopic laser welding machine can realize multi-beam simultaneous processing and multi-station processing, which provides conditions for welding that meets customer needs better.
