A system and associated method of marking a molded vehicle tire with laser engraved information to provide both human visible and machine readable data concerning the tire. Information contained in a barcode on the tire is read at a first station and supplied to a control unit. The physical location of human visible information previously molded into the tire is read from the tire at a second station and supplied to the control unit which uses this information to position a laser located at a third station for engaging additional human visible information pertaining to the manufacture of the tire adjacent the existing visible information to satisfy the Department of Transportation (DOT) tire marking requirements. The additional information also can be laser engraved into the tire in a machine readable encoded format, such as 2D symbols, for subsequent control and verification throughout the life of the tire.

In a multi-beam exposure scanning method, when an irradiation region, which is a region on an object to be irradiated with a single beam, is exposed, the light quantity of the beam is controlled based on an exposed state of another irradiation region around the irradiation region to be exposed. When the other irradiation region near a periphery of the irradiation region to be exposed has not been exposed, the irradiation region is irradiated with a beam having a first light quantity. When the other irradiation region has been exposed, the irradiation region is irradiated with a beam having a second light quantity smaller than the first light quantity. Accordingly, influence of heat due to an adjacent beam can be effectively reduced.

The invention discloses an ultrafast laser metal fine carving method, comprising the following steps: step 1, placing the product to be carved at the processing position of the fine carving device; step 2, after the product to be carved reaches the processing position of the fine carving device, The product to be engraved is triggered by the sensor to press down, and the positioning of the jig mechanism ensures that the surface to be engraved is relatively horizontal to the laser engraving device of the vibrating mirror, so as to realize ultra-fast fine engraving processing; step 3, the laser beam emitted by the laser enters the vibrating mirror through the laser optical path mechanism Laser engraving device; Step 4, the vibrating mirror laser engraving device controls the laser beam to act on the surface of the product to be engraved for fine carving processing; Step 5, the dust removal mechanism blows away the smoke generated on the product surface and performs exhaustion treatment; Step 6, Fine carving After the processing is completed, the product is recycled; the consistency of automation and the efficiency of processing are guaranteed, and at the same time, it can meet the process requirements required by Jingdiao, which is helpful for fast, accurate and fine carving products, and improves the efficiency and yield of production and processing.

The invention relates to a method of freely carving patterns on a pair of glasses. The method of freely carving patterns on the pair of glasses comprises the steps that step 1, a camera with the automatic focal distance adjustment function is used for taking a photo of a lens to be carved, and an electronic photo is obtained; step 2, the electronic photo is uploaded to a computer, and image processing software is used for conducting image matting on the image on the lens to be carved; step 3, the image obtained from the image matting in step 2 is input to a numerical control laser carving machine; step 4, the numerical control laser carving machine is used for carving on each portion of the pair of glasses to obtain a rough pattern; step 5, a car paint pen is used for painting on the rough pattern obtained in step 4 until the rough pattern is painted evenly and completely covered; and step 6, alcohol is used for erasing paint outside the boundary of the rough pattern to obtain a refined pattern before the painted paint is completely dry. According to the method of freely carving patterns on the pair of glasses, control precision is high, and complicated patterns can be obtained.
