Description

TECHNICAL FIELD

[0002] Thin plate flexible laser cutting technology is an advanced processing method, which uses high-energy laser beam to accurately cut materials, and is widely used in metal processing, automobile manufacturing and aerospace and other fields.

[0003] In the thin plate flexible laser cutting workbench disclosed in Chinese patent publication No. CN222059179U, the thin plate flexible laser cutting workbench can realize the rapid feeding and discharging of the plate by setting multiple linear motors and conveying mechanisms. At the same time, after the feeding of the plate is completed, it can realize accurate positioning, thereby effectively improving the cutting accuracy and cutting efficiency of the plate. However, according to the laser cutting device provided by the related field and the existing technology, the adjustment of the distance between the existing laser head and the plate relies on manual operation based on experience. It is not possible to accurately adjust the distance between the laser head and the plate according to the thickness of the plate. If the distance is too large, the diameter of the laser beam focus will increase after focusing, and the energy density will decrease, which will cause the material to be unable to be quickly melted or vaporized. If the distance is too small, the laser beam will not be fully focused before it contacts the plate, and the energy distribution of the light spot will be uneven, with too high central energy and insufficient edge energy. At the same time, the staff cannot intuitively understand the cutting trajectory in advance. For complex cutting patterns or multiple plate splicing and cutting, it is difficult to find possible problems in the cutting path in advance, such as trajectory overlap and unreasonable spacing, which increases the risk of cutting errors.

[0026] The working process is as follows:

[0027] S1, as Figures 3 to 5As shown, when the plate material is in contact with the brush 63, the brush 63 will promote the upward sliding of the measuring rod 61 through the sleeve 62, and at this time, the thickness of the plate material can be quickly obtained by observing the positional relationship between the scale line 611 on the measuring rod 61 and the fixed seat 71;

[0030] S4, as Figure 3 , Figure 4 , Figure 6 and Figure 7 shown, after drawing lines, the measuring rod 61 can be rotated by unscrewing the positioning screw 72, so that the brush 63 deviates from the laser head of the laser 2, and then the measuring rod 61 is pushed upward, so that the brush 63 is no longer in contact with the plate material. After adjustment, the measuring rod 61 can be positioned by screwing the positioning screw 72;
