AI Technical Summary
The existing laser marking machine does not lock after adjustment, which causes the threaded rod to rotate during vibration, affecting the printer position, causing focal length errors, and requiring manual judgment of the optimal focal length, increasing the workload.
The laser marking device employs a combination of electric adjustment and locking components, along with guiding and detection components, to achieve both electric and manual adjustment. This ensures accurate focal length positioning and locks the device in the optimal state. Combined with an electromagnet and synchronous belt system, stable positioning is achieved.
Stable positioning of the laser marking device was achieved, focal length error was reduced, the need for manual judgment was reduced, and marking accuracy and efficiency were improved.
