Laser Machine World for Laser Technology and Laser Products

  Production not only pursues efficiency but also pays attention to quality. The openness and strong practical application capabilities of MRJ-laser laser equipment enable it, when paired with a high-precision galvanometer, to achieve a high efficiency of coding tens of thousands of products per hour. However, efficient coding alone is far from enough. , In sync with production efficiency, detection, and rejection efficiency must also be improved.   In the application of laser inkjet printing, how do we achieve high efficiency, high quality, and low rework to "have the best of both worlds"? This is inseparable from the laser inkjet coding-detection system designed by MRJ-laser  for users.   The codes assigned to products in various industries are not just simple production dates but also include one-dimensional codes, two-dimensional codes, encryption masks, etc. They can be divided into internal codes and external codes according to different application functions. ...

  1.0 Material Description:   The aluminum battery case and battery cover commonly use material 1060 industrial aluminum, its main components are as follows:   The cover has raised edges, and a stepped structure, and is snapped into the aluminum case, with the edges resting on the top of the case wall to prevent laser light leakage from damaging the core.   Welding equipment:   Laser parameters: continuous laser 2kw fiber laser, fiber core diameter 100um, focused spot diameter 200um, system magnification 2 times. 2.0 Ordinary welding Ordinary welding process parameters:   1. Laser power 1200W, speed 80mm\s, +2mm   2. Welding effect: the weld seam weld channel is neat and smooth, there is a regular fish scale pattern at the weld foot, and there is no extra high bulge on the side of the weld seam.   The molten pool is deep V-shaped with a girdle, with a depth of 1.7-1.8mm and a width of 1.4-1.5mm, which is a typical deep-melting laser weld.  ...

Substrate is the underlying material of semiconductor chips, which mainly plays the role of physical support, thermal conductivity and electrical conductivity. Silicon carbide has higher electrical conductivity and stronger thermal stability than traditional silicon materials, is one of the ideal materials for making high-temperature, high-frequency, high-power, high-voltage devices, which are widely used in solar energy, automotive components , charging piles, power supplies and other areas of life and production. Silicon carbide substrate manufacturing needs to go through raw material synthesis, crystal growth, crystal cutting, wafer milling and processing, as well as cleaning, polishing, testing and many other links. Cutting link is one of the key links, due to the great hardness of silicon carbide, Mohs hardness of 9.5, and high brittleness, making the processing link cutting difficult, high breakage rate, some data show that the yield of silicon carbide processing link is about 70...

  Laser cleaning can clean the surface of cultural relics made of different materials such as stone (marble, jade), metal (bronze, iron, etc.), oil painting, ceramics, parchment, paper, ivory, silk textiles, wood, etc., and ensure that there is no residue and no harm. In addition to metal descaling, it is also used for paper de-inking, ceramics removing stone deposit film, and stone artifacts removing grease and deposit film.   The traditional method of protecting artwork is to use mechanical and chemical methods, but with this method, it is difficult to control the process; the mechanical method may remove the artwork's own material, while the chemical agents may penetrate into the artwork and destroy the artwork's pigmentation. Both methods may cause irreparable damage to the artwork.   In the world's cultural heritage sites, laser cleaning technology has been applied to the Xia, Shang, and Zhou bronzes, statues of the ancient Greek era, BC ancient parchment scrolls, m...
