Description

Technical Field

[0001] This utility model belongs to the field of marking equipment technology, specifically relating to a horizontal three-degree-of-freedom laser marking station with a long axis end face. Background Technology

[0002] In industrial production, especially in sectors such as automobile manufacturing, machining, and aerospace, the marking of long-shaft components is crucial for quality traceability, production management, and anti-counterfeiting identification. However, existing laser marking equipment faces numerous difficulties when marking the end faces of long shafts, resulting in inaccurate positioning, time-consuming and labor-intensive adjustments, and low marking efficiency, making it difficult to meet the needs of modern industrial automated production.

[0003] Long shaft components are often heavy, long, with small and complex end faces, and their shaft diameters vary, making it difficult for existing equipment to quickly and accurately achieve marking and positioning. In particular, when marking the end face, it is difficult to place and fix the workpiece, which can easily lead to positional deviations.

[0004] Due to the large weight of the long shaft, the traditional manual adjustment method requires a lot of manpower, which is not only complicated to operate, but may also cause the marking position to be misaligned or the workpiece to be damaged due to improper adjustment; in addition, during the adjustment process, the long shaft may undergo slight deformation due to its own weight, which will further affect the marking accuracy.

[0005] Existing laser marking equipment is usually fixed or single-axis adjustable, which is difficult to adapt to the needs of marking long-axis end faces. This results in repeated adjustments and tests for each marking, increasing production time. At the same time, the equipment's lack of adaptability makes the process of changing and debugging workpieces of different specifications time-consuming, reducing overall production efficiency.

[0006] The change in shaft diameter places higher demands on the marking system. Existing equipment usually lacks the ability to be compatible with workpieces of different shaft diameters, which means that marking workpieces of different specifications requires additional fixtures or modifications, increasing the production costs of enterprises and the difficulty of equipment adaptation.

[0007] Therefore, in view of the above-mentioned technical defects such as insufficient anti-counterfeiting, poor environmental adaptability and low operating efficiency, there is an urgent need for a new label paper marking device to solve the above problems and improve the efficiency, reliability and anti-counterfeiting of label marking.
