Currently the most commonly used one-dimensional code, book bag food packaging, medicine boxes can see, we have no such a concept is a single light iron laser spot welding, regardless of the back cover books, food boxes, or how the drug box pattern color bright, and one-dimensional bar code is black, the bottom are generally white or pale-based, is not it? Or you can now get your side of the one-dimensional look at the code. Here, I tell you, the color is very important, that bar code scanning equipment required for color, while natural junior high school physics book book, elementary school said, and black and white is the color of the biggest. As long as there is color, barcode scanners to read out the exact contents of one-dimensional code out. In the previous section, we discuss the one-dimensional code, and the two-dimensional code is the same, the two-dimensional code scanning equipment also to produce color, correct and complete in order to read its contents. This is why the background is white two-dimensional code, its design is black causes. Now we return to the problem of laser marking machine play barcode scanners can identify the one-dimensional bar code and two-dimensional barcodes, as long as we can make out of the bar code laser coders play a larger and background color can be, for example, white or light-colored or dark gray material in play barcode, or vice versa, in a black or dark-colored, low color, white or light-colored pattern play to be able to play a valid barcode. Company products include: fiber laser marking machines, semiconductor side pump laser marking machine, CO2 laser marking machine, end-pumped laser marking machine, laser inkjet printer and other industrial laser equipment. Krypton lamp laser marking machine to a certain time after the end of life, you need to replace the krypton lamp - lasers, this paper introduce straightforward replacement laser marking machine krypton lamp approach. Replacement laser marking machine krypton lamp should pay special attention: To remember krypton lamp replacement time. General description of laser krypton lamp life of krypton lamp factory for 300 hours, but due to the conditions of use of different users, these times can not serve as the sole basis for the replacement krypton lamp. With the increasing use of time, krypton lamp luminous efficiency decreases, the laser output also will be weakened, many users in order to obtain sufficient laser output power of the laser to increase the current, the krypton lamp luminous enhancement, which makes krypton lamp aging accelerate a vicious circle, sometimes leads to fry light phenomenon. To prevent this from happening, we recommend the user to press the following method to decide whether it should be replaced krypton lamps. When put on a new krypton lamp, laser power meter to record the value of the normal marking time as a standard current value. When krypton lamp aging, increasing the laser power supply current output, but the meter value should not exceed 1.25 times the standard current value. For example: when a new krypton lamp current is 20A marking electrolytic iron laser spot welding, after a period of time, if the current value of the transfer large to 22.5A still can not properly marking, replace the krypton lamp. The first step is to shut down the chiller, laser power, open the upper three cavity cover, remove to replace the lamp or crystal, the replacement into the laser spot welder welding machine, mounted on the chamber cover. Open water-cooled machine laser spot welding, laser power, laser power supply current is transferred (15 ~ 20) A so. Place a small wood or black paper between the diaphragm and the first beam expander, you should see the spot formed by laser ablation. If not, minor adjustments to the former three knobs diaphragm frame, until the spot appears. After three knobs laser commissioning out before adjustment should be repeated so that the diaphragm frame strongest spot, such as a laser is too strong, high brightness can not be observed, can reduce the supply current. Turn off the laser power.
