Laser marking is a very precise processing technology, usually with an accuracy of around 0.1-0.05mm. However, in high-end fields such as medical devices, integrated circuits, and semiconductors, such accuracy is still insufficient. Some tasks with higher processing requirements may require higher accuracy, such as accuracy below 0.05mm. In order to distinguish, this type of processing is generally referred to as high-precision processing, and the laser marking equipment used for this type of processing is also referred to as precision laser marking in the industry.
After combining precision laser marking with a visual system, it can combine the advantages of flexible and fast visual recognition to complete processing tasks more efficiently. Compared with conventional precision laser marking, the main feature of visual precision laser marking is the use of a control system with visual recognition technology.
Compared to ordinary visual laser marking systems, precision visual laser marking control systems mainly differ in the following aspects: Hardware performance: High precision machining requires higher computing power, especially after adding a visual recognition system. The control system needs to achieve high-precision image recognition and processing instruction output in a very short time, so the specifications of chips and other components in the precision visual laser marking control system will be higher.
Software algorithm: After receiving processing instructions from operators, the control system calculates the motion trajectory of the laser beam through software algorithms. Under the requirements of high-precision processing, the algorithm requirements will naturally be higher, which requires developers to have a better mathematical foundation and more complex calculation formulas.
Image recognition ability: According to different recognition abilities, image recognition technology will also have different levels, and image recognition technology used for precision visual laser marking will obviously have a higher level than ordinary visual recognition technology.
Anti interference ability: In complex workshop environments, the operation of marking machines usually faces complex current and magnetic field environments, and the vibration of various equipment can also have a slight impact on processing. To ensure accuracy, the precision vision laser marking control system will deploy more comprehensive anti-interference measures.
In addition to the control system, in order to achieve high-precision visual laser marking processing, other components such as lasers, cameras, machines, etc. also need to be stable and accurate enough. Compared to ordinary visual laser marking, the debugging and maintenance of such processing equipment will be more complicated, and it will also test the technical strength of the manufacturer.
