Description

Technical Field

[0001] This utility model relates to the field of laser processing equipment technology, and in particular to a fully automatic high-precision laser processing equipment. Background Technology

[0002] Laser processing technology, as an advanced manufacturing technology, plays an increasingly important role in modern industrial production. With its advantages such as high energy density and non-contact processing, it is widely used in various fields including cutting, welding, drilling, and surface treatment. As industrial production demands increasing precision and efficiency, and with the development of automation technology, some automated laser processing equipment has emerged on the market. However, these devices still have many limitations in practical applications.

[0003] In existing technologies, automatic feeders (also known as "feeders") are commonly used to automatically supply materials. A picking device then removes the material and places it at a designated location for laser processing. However, the positional accuracy of the material supplied by the feeder is often not high; for example, it may exhibit a certain tilt angle. This leads to insufficient material precision during subsequent picking and placing, thus affecting processing accuracy. Furthermore, existing laser processing heads and picking mechanisms are driven independently by their respective drive systems. Because these are two independent drive systems, achieving precise synchronization is difficult. Additionally, processing and picking require waiting for each system to complete its respective action, impacting production efficiency. Asynchronous actions can also lead to positional deviations, reducing laser processing accuracy. This is especially problematic for high-precision production processes, potentially failing to meet quality standards and increasing equipment and maintenance costs. Therefore, it is necessary to improve existing technologies to overcome their shortcomings. Utility Model Content
