Laser marking tool for positioning optical device

Technical Field

The utility model relates to a laser engraving technical field, in particular to can effectively fix a position laser marking technical level vertical position of a plurality of optical devices fast to make its whole level put frock.

Background

Laser marking technology is one of the largest application areas of laser processing. The laser marking is non-contact processing, can mark on any special-shaped surface, does not deform and generate internal stress on a workpiece, and is suitable for marking materials such as metal, plastic, glass, ceramics, wood, leather and the like. Laser marking is a marking method in which a workpiece is irradiated locally with high-energy-density laser to vaporize a surface layer material or to undergo a chemical reaction of color change, thereby leaving a permanent mark. The laser marking can print various characters, symbols, patterns and the like, and the size of the characters can be from millimeter to micron, which has special significance for the anti-counterfeiting of products. The laser generator generates high-energy continuous laser beam, the focused laser beam acts on the printing material to melt or even gasify the surface material instantaneously, and the required graphic mark is formed by controlling the path of the laser beam on the surface of the material. The laser marking machine adopts a scanning method to mark, namely laser beams are incident on the two reflectors, a computer is used for controlling a scanning motor to drive the reflectors to rotate along X, Y axes respectively, and the laser beams fall on a marked workpiece after being focused, so that laser mark traces are formed. The focused superfine laser beam is like a cutter, the surface material of the object can be removed point by point, and the advanced point is that the marking process is non-contact processing and does not generate mechanical extrusion or mechanical stress. Optical devices (optical devices) are divided into active devices and passive devices, the optical active devices are optoelectronic devices which need external energy to drive and work in an optical communication system and can convert electrical signals into optical signals or convert optical signals into electrical signals, and the optoelectronic devices are hearts of an optical transmission system. The optical passive device is an optoelectronic device which does not need an external energy source to drive operation. In the production process of the optical device, in order to record information (batch number, production date, responsible person, and the like) of each product, conveniently identify the product, control the product quality, prevent counterfeiting and establish a brand, a two-dimensional code or a character is usually engraved on the packaging structure and the shell of the optical device by laser, so that the product has traceability. The type, the style of optical device are various in the optical module field, and special face processing is more complicated, and the surface sculpture of marking the cylindrical body needs its axle center to be on a parallel with the bottom surface, requires that the axle center is on a parallel with planar X or Y axle direction simultaneously, keeps forward and places, just can ensure that the two-dimensional code can successfully be scanned out, guarantees that the rectangle two-dimensional code can not be pasted, can not warp. In order to ensure that the optical device can be effectively positioned, the placing position of the workpiece is generally required to be measured and adjusted, the accuracy of adjusting data by manual measurement has a great uncertainty factor, the control precision is low, the reliability is poor, and the labor intensity of an operator is greatly increased. Because the whole similar cylinder of optical device leads to the fact the removal easily putting the process, causes the positioning inefficacy problem, influences the finished product qualification rate, reduces production efficiency, leads to the cost-push. In order to ensure that the position of an optical device is within a range meeting requirements, the printed two-dimensional code is square and upright and can be identified, a positioning tool is usually placed by adopting laser marking of the optical device, but when the marking is carried out, if micro vibration or rotation in the circumferential direction is generated, the vibration and the rotation affect the positioning stability, so that the marking position of the optical device is deviated, and the precision of the laser marking is affected. If the optical device is not stably placed and the position is not fixed, the operation is complicated, and the laser engraved two-dimensional code is prone to being skewed and blurred, or even is not printed and other bad results are easily caused. Poor marking flexibility, low energy utilization rate, and the like, and can not be adapted to various optical devices. Therefore, the production efficiency of the optical device is seriously influenced, the qualification rate of finished products is reduced, and the production cost is increased.
