3c digital electronic laser welding _ fiber transmission laser welding machine, this technology product has been widely used in the welding of internal structural parts of 3C digital electronic products。 The fiber-optic transmission laser welding machine is a laser welding device that couples a high-energy laser beam into an optical fiber, and after long-distance transmission, collimates into parallel light through a collimating mirror, and then focuses on the workpiece to perform welding。 For flexible welding non-contact welding, it is more flexible。 The fiber-optic transmission laser welding machine laser beam can realize time and energy splitting, and can simultaneously process multiple beams, which provides conditions for more precise welding。
The optical fiber transmission laser welding machine has the advantages of good beam quality, fine spot and flexible installation. 3C digital electronic fiber-optic transmission laser welding machine needs to specifically mention that the optical fiber transmission laser welding machine is applied to a key technology in 3C digital electronic products - real-time energy negative feedback technology. The energy negative feedback technology is a method of comparing the laser energy waveform to be outputted with the actual output energy waveform in real time to determine the input energy of the pump lamp, and then controlling the output energy. The energy negative feedback control technology can accurately control the laser output energy within 3%, and solve the following problems that cause the laser output energy to fluctuate widely:
(1) The fluctuation of the mains affects the fluctuation of the laser output energy
(2) The effect of the difference of each discharge of xenon lamp on the laser output energy
(3) The aging of the xenon lamp leads to a decrease in the output energy of the laser
(4) Fluctuations in the output energy of the laser caused by changes in water flow rate and changes in water temperature.
In order to maintain a stable and good processing state and reduce the product defect rate, laser energy and its waveform are required to have good repeatability, and energy negative feedback control technology is an effective means to solve this problem. With the further development of laser technology, 3c digital electronic laser welding equipment will be more and more widely used, laser technology will drive the industry's integrated, high-precision production.
